MERGER PROPOSAL—YOUR VOTE IS VERY IMPORTANT

Dear Fellow Stockholder:

The board of directors of Metabasis Therapeutics, Inc. has unanimously approved a merger agreement that provides for the merger of Moonstone Acquisition, Inc., a wholly owned subsidiary of Ligand Pharmaceuticals Incorporated, with and into Metabasis. As a result of the merger, Metabasis will become a wholly owned subsidiary of Ligand.

As is more fully described in the accompanying proxy statement/prospectus, in connection with the merger, each share of Metabasis common stock will be converted into the right to receive a pro rata portion of a total cash payment equal to $3,207,500 (cash consideration) less Metabasis’ estimated net liabilities (as defined in the merger agreement) at closing and also less $150,000 to be deposited in the Stockholders’ Representative’s fund. Metabasis currently estimates the total closing payment to be approximately $1.8 million in cash. In addition, each Metabasis stockholder will receive, for each share of Metabasis stock held, (i) one Roche CVR, (ii) one TR Beta CVR, (iii) one Glucagon CVR and (iv) one General CVR (each as defined in “Certain Terms of the Merger Agreement—CVR Agreements” below).

We describe in detail the terms of the merger, including the contingent value rights, in the accompanying proxy statement/prospectus under the caption “Certain Terms of the Merger Agreement” beginning on page 76, which we urge you to read carefully. The common stock of Metabasis is quoted on the Nasdaq Capital Market under the symbol “MBRX”.

The merger cannot be completed unless Metabasis stockholders adopt the merger agreement and approve the merger contemplated by the merger agreement at the special meeting of Metabasis stockholders to be held on [                    ], 2010. We describe in detail the special meeting of Metabasis stockholders in the accompanying proxy statement/prospectus under the caption “The Special Meeting of Metabasis Stockholders” beginning on page 41, which we urge you to read carefully. More information about Ligand, Metabasis and the merger is contained in the accompanying proxy statement/prospectus.

Your vote is very important. Whether or not you plan to attend the special meeting of Metabasis stockholders, please take the time to vote your shares. You may vote your shares by completing, signing, dating and returning the enclosed proxy card as promptly as possible in the enclosed postage-prepaid envelope.

QUESTIONS AND ANSWERS ABOUT THE MERGER

 

Q: Why am I receiving this proxy statement/prospectus?

 

A: Ligand Pharmaceuticals Incorporated, or Ligand, has agreed to acquire Metabasis Therapeutics, Inc., or Metabasis, under the terms of an Agreement and Plan of Merger, dated October 26, 2009 (and as amended), or the merger agreement, that is described in this proxy statement/prospectus. Please see the sections entitled “The Merger” and “Certain Terms of the Merger Agreement” beginning on pages 45 and 76, respectively, of this proxy statement/prospectus. A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A.

In order to complete the transactions contemplated by the merger agreement, including Ligand’s acquisition of Metabasis, Metabasis stockholders must adopt the merger agreement by the affirmative vote of the holders of a majority of the shares of Metabasis common stock outstanding on the record date for the special meeting and all other conditions to the merger must be satisfied or waived. You are receiving this proxy statement/prospectus because you have been identified as a Metabasis stockholder as of [                    ], 2009, the record date for the special meeting, and thus you are entitled to vote at the special meeting. This document serves as a proxy statement/prospectus of Metabasis, used to solicit proxies for the special meeting, and as a prospectus of Ligand, used to offer CVRs to stockholders of Metabasis pursuant to the terms of the merger agreement. This document contains important information about the merger and the special meeting, and you should read it carefully.

 

Q: When and where is the special meeting of Metabasis stockholders?

 

A. The special meeting of Metabasis stockholders will be held on [                    ], 2010, starting at [                    ], local time, at the offices of Cooley Godward Kronish LLP, located at 4401 Eastgate Mall, San Diego, California 92121.

 

Q. On what matters am I being asked to vote on?

 

A. Metabasis stockholders are being asked to consider and vote on the following items:

 

   

the adoption of the merger agreement and approval of the merger;

 

   

a proposal to adjourn the special meeting to a later date, if necessary, to solicit additional proxies in the event there are insufficient votes at the time of the special meeting to adopt the merger agreement and approve the merger; and

 

   

to transact such other business as may properly come before the special meeting and any adjournments or postponements thereof.

 

Q: What is the merger?

 

A: Under the terms of the merger agreement, Moonstone Acquisition, Inc., a wholly-owned subsidiary of Ligand, or Merger Sub, will merge with and into Metabasis, with Metabasis continuing as the surviving entity. The merger of Merger Sub with and into Metabasis is referred to herein as the merger. Upon completion of the merger, each outstanding share of Metabasis common stock will be converted into the right to receive a combination of cash and contingent value rights, or CVRs. For a more complete description of the merger, please see the section entitled “The Merger” beginning on page 45 of this proxy statement/prospectus.

 

Q: As a Metabasis stockholder, what will I receive in the merger?

 

A:

If the merger agreement is adopted by Metabasis’ stockholders and the other conditions to the merger are satisfied or waived, then upon completion of the merger, each share of Metabasis common stock will be

Table of Contents
 

converted into the right to receive a pro rata portion of a total cash payment equal to $3,207,500 (cash consideration) less Metabasis’ estimated net liabilities (as defined in the merger agreement) at closing and also less $150,000 to be deposited in the Stockholders’ Representative’s fund. Metabasis currently estimates the total closing payment to be approximately $1.8 million in cash. In addition, each Metabasis stockholder will receive, for each share of Metabasis stock held, (i) one Roche CVR, (ii) one TR Beta CVR, (iii) one Glucagon CVR and (iv) one General CVR (each as defined in “Certain Terms of the Merger Agreement—CVR Agreements” below).

Please see the sections entitled “The Merger—General” and “Certain Terms of the Merger Agreement—CVR Agreements” beginning on pages 45 and 93, respectively, of this proxy statement/prospectus for a description of the merger consideration.

 

Q: Who will be appointed Stockholders’ Representative for the merger?

 

A: David F. Hale, currently Executive Chairman and Acting Principal Executive Officer of Metabasis, will be appointed as Stockholders’ Representative upon adoption of the merger agreement.

 

Q: What is required to consummate the merger?

 

A: To consummate the merger, Metabasis stockholders must adopt the merger agreement, which requires the affirmative vote of the holders of a majority of the voting power of the shares of Metabasis common stock outstanding on the record date for the special meeting. In addition to obtaining Metabasis stockholder approval, each of the other closing conditions set forth in the merger agreement must be satisfied or waived. For a more complete description of the closing conditions under the merger agreement, please see the section entitled “Certain Terms of the Merger Agreement—Conditions to the Merger” beginning on page 88 of this proxy statement/prospectus.

 

Q: How does Metabasis’ board of directors recommend that I vote?

 

A: After careful consideration, Metabasis’ board of directors approved the merger agreement and the merger and unanimously declared that the merger agreement and the merger, upon the terms and subject to the conditions set forth in the merger agreement, are advisable and in the best interests of Metabasis and its stockholders. Accordingly, Metabasis’ board of directors unanimously recommends that you vote FOR the proposal to adopt the merger agreement and approve the merger, and FOR the proposal to adjourn the special meeting to a later date or dates, if necessary, to solicit additional proxies in the event there are insufficient votes at the time of the special meeting to adopt the merger agreement and approve the merger. To review the background of the merger and Metabasis’ board of directors’ reasons for recommending the merger in greater detail, see the sections entitled “The Merger—Background of the Merger” and “The Merger—Metabasis’ Reasons for the Merger; Recommendation of Metabasis’ Board of Directors” beginning on pages 47 and 53, respectively, of this proxy statement/prospectus.

 

Q: What risks should I consider in deciding whether to vote in favor of the merger?

 

A: You should carefully review the section of this proxy statement/prospectus entitled “Risk Factors” beginning on page 22 of this proxy statement/prospectus, which sets forth certain risks and uncertainties related to the merger, risks and uncertainties to which the combined company’s business will be subject and risks and uncertainties to which Ligand, as an independent company, is subject.

 

Q: When do the parties expect to complete the merger?

 

A: The parties are working towards completing the merger as quickly as possible. The merger is expected to close during the first calendar quarter of 2010. However, because completion of the merger is subject to various conditions, Ligand and Metabasis cannot predict the exact timing of the merger or whether the merger will occur at all.

Table of Contents
Q: Am I entitled to appraisal rights?

 

A: Under Delaware law, holders of Metabasis common stock are entitled to appraisal rights in connection with the merger pursuant to Section 262(d) of the Delaware General Corporation Law. Failure to take any of the steps required under Section 262(d) of the Delaware General Corporation Law on a timely basis may result in a loss of those appraisal rights. The provisions of the Delaware General Corporation Law that grant appraisal rights and govern such procedures are attached as Annex F to this proxy statement/prospectus. For a more complete description of your appraisal rights, see the section entitled “The Merger—Appraisal Rights of Dissenting Metabasis Stockholders” on page 72 of this proxy statement/prospectus.

 

Q: What will happen to any options or warrants to acquire Metabasis common stock in the merger?

 

A: Metabasis’ board of directors, by operation of existing agreements or by resolution, will take all requisite actions such that immediately before the effective time of the merger each holder of outstanding Metabasis options shall be entitled to exercise in full all Metabasis options held by such holder by paying the exercise price therefor in exchange for shares of Metabasis common stock in accordance with the applicable Metabasis equity plan or arrangement. All outstanding Metabasis options not exercised, shall be terminated and canceled at the time of the merger without any payment or liability on the part of Metabasis. No replacement options will be issued.

Metabasis has agreed to use reasonable best efforts to enter into agreements with the holders of outstanding Metabasis warrants to terminate and cancel all such warrants, effective immediately before the effective time of the merger, without any payment or liability on the part of Metabasis. If any Metabasis warrant remains outstanding after the effective time of the merger and the holder thereof exercises such Metabasis warrant before its expiration or termination date, then Ligand shall issue and pay in respect of such exercised Metabasis warrant, in exchange for the payment of the applicable exercise price, on a per-exercised-share basis, equivalent consideration as is paid in respect of each issued and outstanding share of Metabasis common stock as of immediately before the merger.

See the section entitled “Certain Terms of the Merger Agreement—Metabasis Stock Options and Warrants” beginning on page 78 of this proxy statement/prospectus.

 

Q: Will my rights as a Metabasis stockholder change as a result of the merger?

 

A: Yes. You will no longer be a Metabasis stockholder, and you will become a holder of Ligand CVRs as a result of the merger and will have rights after the completion of the merger that are governed by California law and the CVR agreements.

 

Q: Will I be able to trade the CVRs that I receive in connection with the merger?

 

A: The CVRs issued to Metabasis stockholders in connection with the merger will not be listed on any securities exchange but will be generally tradable, subject to certain procedures as set forth in more detail in this proxy statement/prospectus and the CVR agreements.

 

Q: What are the United States federal income tax consequences of the merger?

 

A: The receipt of the merger consideration by a U.S. holder in exchange for Metabasis shares will be a taxable transaction for United States federal income tax purposes. The amount of gain or loss a U.S. holder recognizes, and the timing of such gain or loss, depends in part on the United States federal income tax treatment of the CVRs, with respect to which there is substantial uncertainty. A Metabasis stockholder’s gain or loss will also be determined by the stockholder’s tax basis in his shares of Metabasis common stock. For a more complete description of the tax consequences of the merger, see the section entitled “The Merger—Material United States Federal Income Tax Consequences of the Merger” beginning on page 69 of this proxy statement/prospectus.

Table of Contents

Tax matters are very complicated, and the tax consequences of the merger to a particular stockholder will depend in part on such stockholder’s circumstances. Accordingly, you are urged to consult your own tax advisor for a full understanding of the tax consequences of the merger to you, including the applicability and effect of federal, state, local and foreign income and other tax laws.

 

Q: What should I do now?

 

A: You should carefully read this proxy statement/prospectus, including its annexes and the documents incorporated by reference, and consider how the merger will affect you. Ligand and Metabasis urge you to then respond by voting your shares through one of the following means:

 

   

by mail, by completing, signing, dating and mailing each proxy card (if you are a registered stockholder, meaning that you hold your stock in your name) or voting instruction card (if your shares are held in “street name,” meaning that your shares are held in the name of a broker, bank or other nominee) and returning it in the envelope provided;

 

   

via the Internet, at the address provided on each proxy card or voting instruction card (if your bank, broker or nominee makes Internet voting available);

 

   

via telephone, using the toll-free number listed on each proxy card or voting instruction card (if your bank, broker or nominee makes telephone voting available); or

 

   

in person, by attending the special meeting and submitting your vote in person (special requirements apply if your shares are held in “street name” and you wish to vote in person).

 

Q: What happens if I do not return a proxy card or otherwise vote?

 

A: The failure to return your proxy card, vote using the telephone or via the Internet or vote in person at the special meeting will have the same effect as voting AGAINST adoption of the merger agreement and approval of the merger, and will have no effect on the proposal for possible adjournment of the special meeting.

 

Q: What happens if I return a signed and dated proxy card but do not indicate how to vote my proxy?

 

A: If you do not include instructions on how to vote your properly signed and dated proxy, your shares will be voted FOR adoption of the merger agreement and approval of the merger, and FOR approval of possible adjournment, if any, of the special meeting.

 

Q: May I vote in person at the special meeting?

 

A: If your shares of Metabasis common stock are registered directly in your name with Metabasis’ transfer agent, you are considered, with respect to those shares, the stockholder of record, and the proxy materials and proxy card are being sent directly to you by Metabasis. If you are a Metabasis stockholder of record, you may attend the special meeting and vote your shares in person, rather than signing and returning your proxy card or otherwise voting by Internet or telephone.

If your shares of Metabasis common stock are held in a brokerage account or by another nominee, you are considered the beneficial owner of shares held in “street name,” and the proxy materials are being forwarded to you together with a voting instruction card. As the beneficial owner, you are also invited to attend the special meeting. Since a beneficial owner is not the stockholder of record, you may not vote these shares in person at the special meeting unless you obtain a “legal proxy” from the broker, trustee or nominee that holds your shares, giving you the right to vote the shares at the special meeting.

Table of Contents
Q: May I change my vote after I have mailed my signed and dated proxy card or otherwise voted?

 

A: Yes. If you have submitted a proxy, you may change your vote at any time before your proxy is voted at the Metabasis special meeting of stockholders. You can do this one of four ways. First, you can send a written, dated notice to the Corporate Secretary of Metabasis stating that you would like to revoke your proxy. Second, you can complete, sign, date and submit (in time to reach Metabasis before the beginning of the special meeting) a new later-dated proxy card. Third, you can submit another proxy via the Internet or telephone. Fourth, if you are a stockholder of record or you obtain a “legal proxy” from your broker, trustee or nominee, you can attend the special meeting and vote in person. Your attendance at the special meeting alone will not revoke your proxy.

If you have instructed a broker to vote your shares, you must follow the directions received from your broker to change those instructions.

 

Q: If my shares are held in “street name” by my broker, will my broker automatically vote my shares for me?

 

A: No. Your broker will not be able to vote your shares without instructions from you. Therefore, you should provide your broker with instructions on how to vote your shares, following the procedure provided by your broker. The failure to provide such voting instructions to your broker will have the same effect as voting AGAINST adoption of the merger agreement and approval of the merger, and will have no effect on the proposal for possible adjournment of the special meeting.

 

Q: Should I send in my Metabasis stock certificates now?

 

A: No. If you are a Metabasis stockholder, after the merger is completed a letter of transmittal will be sent to you informing you where to deliver your Metabasis stock certificates in order to receive the merger consideration. You should not send in your Metabasis common stock certificates before receiving the letter of transmittal.

 

Q: Who is soliciting this proxy?

 

A: Metabasis is conducting this proxy solicitation and will bear the cost of soliciting proxies. In addition, Metabasis may reimburse brokers, banks and other custodians, nominees and fiduciaries representing beneficial owners of shares for their expenses in forwarding soliciting materials to such beneficial owners. Metabasis’ directors, officers and employees may also solicit proxies by personal interview, mail, e-mail, telephone, facsimile or other means of communication. These persons will not be paid additional remuneration for their efforts.

 

Q: Who can help answer my additional questions?

 

A: Metabasis stockholders who would like additional copies, without charge, of this proxy statement/prospectus or have additional questions about the merger, including the procedures for voting their shares of Metabasis common stock, should contact:

Metabasis Therapeutics, Inc.

Purpose of the Meeting. At the special meeting, the Metabasis stockholders will be asked to consider and vote upon the following matters:

 

  1. A proposal to adopt the Agreement and Plan of Merger, dated as of October 26, 2009 (and as amended), by and among Ligand Pharmaceuticals Incorporated, Moonstone Acquisition, Inc., a wholly owned subsidiary of Ligand, a Metabasis’ stockholders’ representative, and Metabasis, and approve the merger contemplated by the merger agreement. A copy of the merger agreement is attached as Annex A to this proxy statement/prospectus accompanying this notice and the forms of CVR agreements related thereto are attached as Annex B, Annex C, Annex D and Annex E to this proxy statement/prospectus accompanying this notice;

 

  2. A proposal to adjourn the special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the special meeting to adopt the merger agreement and approve the merger; and

 

  3. To transact such other business as may properly come before the special meeting and any adjournments or postponements thereof.

Quorum Required. Metabasis’ bylaws provide that the holders of a majority of the shares of Metabasis common stock issued and outstanding and entitled to vote at the special meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business at the special meeting. Abstentions and broker non-votes will be counted as present for the purpose of determining the presence of a quorum.

Voting Rights. Metabasis common stock is the only type of security entitled to vote at the special meeting. On [                    ], 2009, the record date for determination of stockholders entitled to vote at the special meeting, there were [            ] shares of Metabasis common stock outstanding. Each Metabasis stockholder of record on [                    ], 2009 is entitled to one vote for each share of Metabasis common stock held by such stockholder on that date. All votes will be tabulated by the inspector of election appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes.

Proxies. Whether or not you are able to attend Metabasis’ special meeting of stockholders, you are urged to complete and return the enclosed proxy, which is solicited by Metabasis’ board of directors and which will be voted as you direct on your proxy card when properly completed. In the event no directions are specified, such proxies will be voted FOR the adoption of the merger agreement and approval of the merger, FOR the proposal to adjourn the special meeting to permit further solicitation of proxies if there are not sufficient votes to adopt the merger agreement and approve the merger, and in the discretion of the proxy holders as to any other matters that may properly come before the special meeting. All shares represented by a valid proxy received before the special meeting will be voted.

Revocation of Proxies. You may also revoke or change your proxy at any time before the special meeting. To do this, send a written notice of revocation or another signed proxy with a later date to the Secretary at Metabasis’ principal executive offices in time to arrive before the beginning of the special meeting. If you are a stockholder of record or you obtain a “legal proxy” from your broker, trustee or nominee, you may also revoke your proxy by attending the special meeting and voting in person.

Metabasis Votes Required. The affirmative vote of the holders of record of a majority of the outstanding shares of Metabasis common stock is required to adopt the merger agreement and approve the merger, and the affirmative vote of the holders of record of a majority of the shares of Metabasis common stock present and entitled to vote at the special meeting is required to adopt the proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies. If a broker or other nominee holding shares of Metabasis common stock or a holder of Metabasis common stock fails to vote on the adoption of the merger agreement and the approval of the merger or responds to that proposal with an “abstain” vote, it will have the same effect as a vote against that proposal. If a broker or other nominee holding shares of Metabasis common stock or a holder of Metabasis common stock responds to the proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies with an “abstain” vote, it will have the same effect as a vote against that proposal. If a broker or other nominee holding Metabasis common stock or a holder of Metabasis common stock fails to vote on the proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies, it will have no effect on the outcome of the vote for that proposal.

As of [                    ], 2009, (i) the directors and executive officers of Metabasis beneficially owned [            ] shares of Metabasis common stock entitled to vote, representing approximately [    ]% of the outstanding shares of Metabasis common stock entitled to vote at the special meeting and (ii) Ligand and its affiliates beneficially owned [            ] shares of Metabasis common stock entitled to vote, representing approximately 28.9% of the outstanding shares of Metabasis common stock entitled to vote at the special meeting. However, due to the voting agreements described below, approximately [    ]% of the outstanding shares of Metabasis common stock are included in both groups; and so, the aggregate total beneficially owned is [    ]%.

MPM Asset Management Investors 2000 B LLC, MPM BioVentures II, L.P., MPM BioVentures II-QP, L.P., MPM BioVentures GMBH&Co Parallel- Beteiligungs KG, InterWest Partners VII, L.P., InterWest Investors VII, L.P. and all the directors and officers of Metabasis as of October 26, 2009, who as of that date collectively owned approximately 28.9% of the outstanding shares of Metabasis common stock, have entered into voting agreements with Ligand pursuant to which such stockholders have agreed, among other things, to vote the shares of common stock of Metabasis owned by them in favor of adopting the merger agreement and approving the merger. For a description of the voting agreements, see “Certain Terms of the Merger Agreement—Voting Agreements” beginning on page 101 of this proxy statement/prospectus.

Solicitation of Proxies. Metabasis will bear the cost of this solicitation, including the printing and mailing of this proxy statement/prospectus, the proxy and any additional soliciting material furnished to the Metabasis stockholders. Copies of solicitation material will be furnished to brokerage houses, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward this solicitation material to such beneficial owners. In addition, Metabasis may reimburse such persons for their costs of forwarding the solicitation material to such beneficial owners. The original solicitation of proxies by mail may be supplemented by solicitation by telephone, email, facsimile or other means by directors, officers, employees or agents of Metabasis. No additional compensation will be paid to these individuals for any such services.

Risk Factors

Recommendation to Metabasis’ Stockholders

Metabasis’ board of directors has unanimously adopted the merger agreement and approved the merger. The board of directors of Metabasis recommends that Metabasis stockholders vote FOR the adoption of the merger agreement and approval of the merger, and FOR the approval of the proposal to adjourn the special meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of the adoption of the merger agreement and approval of the merger, at the time of the special meeting.

Merger Structure; Merger Consideration

In the merger, Merger Sub will merge with and into Metabasis, with Metabasis continuing as the surviving entity. Upon completion of the merger, if the merger agreement is adopted by Metabasis’ stockholders and the other conditions to the merger are satisfied or waived, each share of Metabasis common stock will be converted into the right to receive a pro rata portion of a total cash payment equal to $3,207,500 less Metabasis’ estimated net liabilities (as defined in the merger agreement) at closing and also less $150,000 to be deposited in the Stockholders’ Representative’s fund. Metabasis currently estimates the total closing payment to be approximately $1.8 million in cash. In addition, each Metabasis stockholder will receive, for each share of Metabasis stock held, (i) one Roche CVR, (ii) one TR Beta CVR, (iii) one Glucagon CVR and (iv) one General CVR (each as defined in “Certain Terms of the Merger Agreement—CVR Agreements” below).

The CVR agreements set forth the rights that former Metabasis stockholders will have with respect to each CVR to be held by them after the closing of the merger. Each Metabasis stockholder will receive one CVR under each of the four CVR agreements for each share of Metabasis stock held. The CVRs will not be listed on any securities exchange but will be generally tradable, subject to certain procedures.

Treatment of Stock Options and Warrants

Metabasis’ board of directors will take, except to the extent that by virtue of existing agreements no action is required, all requisite actions such that each holder of outstanding Metabasis options shall be entitled to exercise in full all Metabasis options held by such holder immediately before the effective time of the merger, and such that all outstanding Metabasis options not exercised before the effective time of the merger shall be terminated and canceled without any payment by Metabasis.

Metabasis has agreed to use reasonable best efforts to enter into agreements with the holders of outstanding Metabasis warrants to terminate and cancel all such warrants, effective immediately before the effective time of the merger, without any payment or liability on the part of Metabasis. If any Metabasis warrant remains outstanding after the effective time of the merger and the holder thereof exercises such Metabasis warrant before its expiration or termination date, then Ligand shall issue and pay in respect of each such exercised Metabasis warrant, on a per-exercised-share basis, equivalent consideration as is paid in respect of each issued and outstanding share of Metabasis common stock as of immediately before the merger.

See the section entitled “Certain Terms of the Merger Agreement—Metabasis Stock Options and Warrants” beginning on page 78 of this proxy statement/prospectus.

Metabasis’ Reasons for the Merger

After careful consideration, Metabasis’ board of directors adopted the merger agreement and approved the merger and unanimously declared that the merger agreement and the merger, upon the terms and subject to the conditions set forth in the merger agreement, are advisable and in the best interests of Metabasis and its stockholders. Metabasis’ board of directors consulted with Metabasis’ senior management, as well as Metabasis’ financial advisor and legal counsel, in reaching its decision to approve the merger.

Please see the section entitled “The Merger—Metabasis’ Reasons for the Merger; Recommendation of Metabasis Board of Directors” beginning on page 53 of this proxy statement/prospectus for a full discussion of the factors that Metabasis’ board of directors considered in reaching its decision to approve the merger.

Opinion of Metabasis’ Financial Advisor

On October 26, 2009, Merriman Curhan Ford & Co., or Merriman, rendered its opinion to Metabasis’ board of directors that, as of October 26, 2009, and based upon and subject to the factors and assumptions set forth therein, the merger consideration to be received by the holders of Metabasis common stock pursuant to the merger agreement is fair from a financial point of view to such holders.

The full text of the written opinion of Merriman, dated October 26, 2009, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex G to this proxy statement/prospectus and is incorporated by reference herein. Merriman provided its opinion for the information and assistance of Metabasis’ board of directors in connection with its consideration of the merger in the form of the merger agreement, dated as of October 26, 2009. Merriman did not provide information or assistance to Metabasis’ board of directors in connection with its consideration of the amendment to the merger agreement, dated as of November 25, 2009. The Merriman opinion is not a recommendation as to how any holder of Metabasis common stock should vote with respect to the merger or any other matter.

Ligand’s Reasons for the Merger

Ligand believes that the merger will enable Ligand to enhance its portfolio of partnerships, pipeline assets and drug discovery resources, and build long-term stockholder value. Please see the section entitled “The Merger—Ligand’s Reasons for the Merger” beginning on page 65 of this proxy statement/prospectus for a full discussion of the factors that Ligand’s board of directors considered in reaching its decision to approve the merger.

However, there can be no assurance that the benefits of the potential growth, synergies or opportunities considered by Ligand’s board of directors will be achieved through completion of the merger. Achieving Ligand’s objectives is subject to particular risks which are discussed in the section entitled “Risk Factors” beginning on page 22 of this proxy statement/prospectus.

Interests of Metabasis’ Officers and Directors in the Merger

In considering the recommendation of Metabasis’ board of directors that you vote to adopt the merger agreement, you should be aware that some of Metabasis’ executive officers and directors may have economic interests in the merger that are different from, or in addition to, those of Metabasis’ stockholders generally. See “The Merger—Interests of Metabasis’ Executive Officers and Directors in the Merger” beginning on page 66 of this proxy statement/prospectus.

Metabasis’ board of directors was aware of and considered these interests, among other matters, in approving the merger agreement and the merger, and in making its recommendation that Metabasis’ stockholders vote to adopt the merger agreement and approve the merger.

Stockholders’ Representative

David F. Hale, currently Executive Chairman and Acting Principal Executive Officer of Metabasis, will be appointed as Stockholders’ Representative upon adoption of the merger agreement. As Stockholders’ Representative, Mr. Hale will (a) negotiate and enforce (or settle) matters arising under the merger agreement, (b) accept delivery of notices, (c) monitor fulfillment of Ligand’s guaranteed funding obligations, (d) confirm satisfaction of Ligand’s obligations under the CVR agreements, (e) negotiate and enforce (or settle) matters with respect to the amounts to be paid to the holders of CVRs and (f) enter into binding amendments or waivers of the former stockholders’ and the CVR holders’ rights under the merger agreement and the CVR agreements. As compensation for his services as Stockholders’ Representative, Mr. Hale will be paid $45,000 in annual compensation for the duration of his services. In addition, the Stockholders’ Representative shall not be

responsible for any loss suffered by, or liability of any kind to, the stockholders or holders of CVRs arising out of any act done or omitted by the Stockholders’ Representative in connection with the acceptance or administration of the Stockholders’ Representative’s duties, unless such act or omission involves gross negligence or willful misconduct. See “Certain Terms of the Merger Agreement—Stockholders’ Representative” beginning on page 84 of this proxy statement/prospectus.

Conditions to the Merger

The obligations of Ligand, Merger Sub and Metabasis to consummate and effect the merger are subject to the satisfaction, at or before the effective time of the merger, of a number of conditions, including, among others, the following:

 

   

the merger agreement shall have been approved by Metabasis’ stockholders;

 

   

there shall be no order or injunction in effect, nor any law, statute or regulation enacted or adopted, preventing completion of the merger; and

 

   

the registration statement on Form S-4 (of which this proxy statement/prospectus forms a part) shall have been declared effective by the SEC.

In addition to the conditions above, the merger agreement provides that the obligations of Ligand and Merger Sub to consummate and effect the merger are subject to the satisfaction, at or before the effective time of the merger, of the following conditions, among others:

 

   

the representations and warranties of Metabasis in the merger agreement must be accurate, except for such inaccuracies that would not reasonably be expected to have a material adverse effect (subject to defined exceptions);

 

   

Metabasis shall have performed or complied in all material respects with all covenants required to be performed by it;

 

   

since the date of the merger agreement, there shall not have occurred and be continuing any event or development which, individually or in the aggregate (and subject to defined exceptions), has had or would reasonably be expected to have a material adverse effect on Metabasis;

 

   

Metabasis shall have obtained third-party consents and/or approvals (subject to defined exceptions); and

 

   

no more than 1,750,000 shares of Metabasis common stock shall be eligible to assert dissenters’ rights.

Termination of the Merger Agreement

Each of Ligand and Metabasis may terminate the merger agreement by mutual consent or if:

 

   

the Metabasis stockholders do not approve the merger agreement;

 

   

the merger has not been consummated by February 15, 2010, unless the terminating party’s failure to comply with the merger agreement is the cause of the failure of the merger to occur on or before this date; or

 

   

a final, permanent legal prohibition prevents the consummation of the merger, unless the terminating party has failed to use its reasonable best efforts to prevent or resolve such legal prohibition or such legal prohibition is attributable to the failure of such party to comply with the merger agreement.

Ligand may terminate the merger agreement if:

 

   

a change in recommendation of the Metabasis board of directors has occurred (as described under “Certain Terms of the Merger Agreement—Termination of the Merger Agreement” beginning on page 91 of this proxy statement/prospectus);

 

   

Metabasis breaches its representations and warranties set forth in the merger agreement, unless such breaches would not reasonably be expected to have a material adverse effect or impair Metabasis’ ability to perform its obligations under the merger agreement or impair the ability of Ligand to enjoy the intended benefits of the merger, subject to Metabasis’ ability to timely cure such breaches as provided in the merger agreement; or

 

   

Metabasis breaches or fails to perform in any material respect its obligations pursuant to the merger agreement, subject to Metabasis’ ability to timely cure such breaches as provided in the merger agreement.

Metabasis may terminate the merger agreement if:

 

   

Ligand or Merger Sub breach their representations and warranties set forth in the merger agreement, unless such breaches would not reasonably be expected to have a material adverse effect or impair Ligand’s ability to perform its obligations under the merger agreement, subject to their ability to timely cure such breaches as provided in the merger agreement;

 

   

Ligand or Merger Sub breach or fail to perform in any material respect their obligations pursuant to the merger agreement, subject to their ability to timely cure such breaches as provided in the merger agreement; or

 

   

if the Metabasis board of directors authorizes Metabasis, subject to complying with the terms of the merger agreement, to accept a superior proposal (as described under “Certain Terms of the Merger Agreement—Termination of the Merger Agreement” beginning on page 91 of this proxy statement/prospectus).

Limitation on Metabasis’ Ability to Consider Other Acquisition Proposals

Metabasis has agreed that it shall not, and shall not authorize or permit Metabasis’ and Metabasis’ subsidiaries’, or any of their respective directors, officers, employees, investment bankers, attorneys and other agents or representatives to, directly or indirectly, subject to specified exceptions:

 

   

solicit, initiate, knowingly encourage or knowingly induce the making, submission or announcement of an acquisition proposal (as defined in the section entitled “Certain Terms of the Merger Agreement—Limitation on Metabasis’ Ability to Consider Other Acquisition Proposals” beginning on page 85 of this proxy statement/prospectus);

 

 

14


Table of Contents
   

furnish any non-public information relating to Metabasis in response to or in connection with an acquisition proposal;

 

   

participate or engage in discussions or negotiations with respect to an acquisition proposal;

 

   

approve, endorse or recommend to the stockholders of Metabasis any acquisition proposal; or

 

   

withdraw or modify the recommendation of the board of directors of Metabasis that Metabasis stockholders vote to adopt the merger agreement.

See “Certain Terms of the Merger Agreement—Limitation on Metabasis’ Ability to Consider Other Acquisition Proposals” beginning on page 85 of this proxy statement/prospectus.

Termination Fee

Metabasis has agreed to pay a $400,000 termination fee to Ligand if:

 

   

the Metabasis board of directors authorizes Metabasis to accept (or to enter into a written agreement for a transaction constituting) a superior proposal or changes its recommendation with respect to the merger; or

 

   

if Ligand terminates the merger agreement as a result of (i) Metabasis’ representations and warranties not being true and correct, except where the failure of any such representation or warranty to be true and correct would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on Metabasis or impair in any material respect the ability of Metabasis to perform its obligations under the merger agreement or the ability of Ligand to enjoy in all material respects the intended benefit of the merger and the transactions contemplated thereby; or (ii) Metabasis’ material breach or failure to perform or comply with any obligation, agreement or covenant required by the merger agreement.

Metabasis has also agreed to pay a $250,000 termination fee to Ligand if:

 

   

(i) Ligand or Metabasis terminates the merger agreement as a result of failure to obtain the required vote at the special Metabasis stockholders meeting or at any adjournment thereof, or (ii) Ligand or Metabasis terminates the merger agreement as a result of the merger not being consummated by the February 15, 2010 outside date;

 

   

neither Ligand nor Merger Sub shall have materially breached any of its representations, warranties or covenants contained in the merger agreement; and

 

   

at or before the time of any such termination of the merger agreement an acquisition proposal shall have been made (and such acquisition proposal shall not have been withdrawn before the time of the termination of the merger agreement) and within 12 months after the date of termination of the merger agreement, Metabasis or any Metabasis subsidiary consummates an acquisition transaction or enters into an agreement to consummate an acquisition transaction that is subsequently consummated.

Fees and Expenses

The merger agreement provides that, regardless of whether the merger is consummated, each party will pay its own expenses incident to preparing for, entering into and carrying out the merger agreement and the transactions contemplated by the merger agreement. Metabasis’ expenses of this kind would reduce Metabasis’ net cash and thus would reduce the merger consideration payable in the merger to Metabasis stockholders.

Tax Matters

The receipt of the merger consideration by a United States holder in exchange for Metabasis common stock should be a taxable transaction for United States federal income tax purposes. The amount of gain or loss a United States holder recognizes, and the timing and potentially the character of a portion of such gain or loss, depends on the United States federal income tax treatment of the CVRs, with respect to which there is substantial uncertainty. A Metabasis stockholder’s gain or loss will also be determined by the stockholder’s tax basis in his shares of Metabasis common stock. For a more complete description of the tax consequences of the merger, see the section entitled “The Merger—Material United States Federal Income Tax Consequences of the Merger” beginning on page 69 of this proxy statement/prospectus.

Tax matters are very complicated, and the tax consequences of the merger to a particular stockholder will depend in part on such stockholder’s circumstances. Accordingly, you are urged to consult your own tax advisor for a full understanding of the tax consequences of the merger to you, including the applicability and effect of federal, state, local and foreign income and other tax laws.

Anticipated Accounting Treatment

Ligand will account for the merger under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations, as amended. See “The Merger—Anticipated Accounting Treatment” beginning on page 72 of this proxy statement/prospectus.

Regulatory Filings and Approvals

Neither Ligand nor Metabasis is aware of any material governmental or regulatory requirements that must be complied with regarding the merger, other than the effectiveness of the registration statement of which this proxy statement/prospectus is a part and compliance with applicable provisions of Delaware law.

Appraisal Rights

Holders of Metabasis common stock are entitled to appraisal rights under Delaware law. See the section entitled “The Merger—Appraisal Rights of Dissenting Metabasis Stockholders” beginning on page 72 of this proxy statement/prospectus.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The selected unaudited pro forma condensed combined financial information presented below is based on, and should be read together with, the historical information that Ligand and Metabasis have presented in their respective filings with the SEC and the pro forma information that appears elsewhere in this proxy statement/prospectus. See the sections entitled “Unaudited Pro Forma Condensed Combined Financial Information” and “Where You Can Find More Information” beginning on pages 105 and 114, respectively, of this proxy statement/prospectus.

The selected unaudited pro forma condensed combined balance sheet as of September 30, 2009 gives effect to the proposed merger as if it had occurred on September 30, 2009, and combines the historical balance sheets of Ligand and Metabasis as of September 30, 2009. The selected unaudited pro forma condensed combined statements of operations for the year ended December 31, 2008 and for the nine months ended September 30, 2009 are presented as if the proposed merger had occurred on January 1, 2008, and combines the historical results of Ligand and Metabasis for the year ended December 31, 2008 and for the nine months ended September 30, 2009, respectively.

The pro forma adjustments related to the merger are based on a preliminary purchase price allocation whereby the estimated cost to acquire Metabasis was allocated to the assets acquired and the liabilities assumed based upon their estimated fair values. A final purchase price allocation will be performed using fair value as of the date of completion of the merger. Differences between the preliminary and final purchase price allocations could have a material impact on the accompanying unaudited pro forma condensed combined financial statement information and Ligand’s future results of operations and financial position. The selected unaudited pro forma condensed combined financial statements do not reflect the realization of potential cost savings or synergistic advantages, or any related restructuring or integration costs. Certain cost savings or synergistic advantages may result from the merger, however, there can be no assurance that these cost savings or synergistic advantages will be achieved.

The selected unaudited pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of the combined financial positions or results of operations in future periods or the results that actually would have been realized if the proposed merger had been completed as of the dates indicated.

RISK FACTORS

If the merger is completed, Ligand and Metabasis will operate as a combined company in a market environment that is difficult to predict and that involves significant risks, many of which will be beyond the combined company’s control. In addition to information regarding Ligand and Metabasis contained in, or incorporated by reference into, this proxy statement/prospectus, you should carefully consider the risks described below before voting your shares. Additional risks and uncertainties not presently known to Ligand and Metabasis or that they do not currently believe are important to an investor, if they materialize, also may adversely affect the merger, Ligand, Metabasis and the combined company. A discussion of additional risks and uncertainties regarding Ligand and Metabasis can be found in the information that is incorporated by reference in this proxy statement/prospectus and referred to in the section entitled “Where You Can Find More Information” beginning on page 114 of this proxy statement/prospectus. If any of the events, contingencies, circumstances or conditions described in the following risks actually occur, Ligand’s and Metabasis’ respective businesses, financial condition or their results of operations (both separately and as combined) could be seriously harmed. If that happens, the trading price of Ligand common stock or Metabasis common stock could decline and you may lose part or all of your investment.

Risks Related to the Merger and the Combination of the Companies

Unless certain events occur, no payments will be made under the CVRs.

As described in more detail in the section entitled “Certain Terms of the Merger Agreement—CVR Agreements” beginning on page 93 of this proxy statement/prospectus, the CVR agreements set forth the rights of the Metabasis stockholders to receive payments under the CVRs. The nature of rights under the CVR agreements and the CVRs is contractual, and the CVR holders have no rights except for those expressly set forth in the CVR agreements.

The events that result in contingent payments may not occur due to numerous factors. Among other things:

 

   

Ligand shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, over any continued operation of, development of or investment in the applicable drug development programs. Therefore Ligand might not continue operation of, develop or invest in an applicable drug development program in such a way as to facilitate creating or optimizing sale or licensing transactions which could result in CVR payments.

 

   

Ligand shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, over when (if ever) and whether to pursue, or enter into, a licensing agreement and/or sale agreement and/or similar agreement with respect to the applicable drug development programs, technology or intellectual property, and upon what terms and conditions. Therefore Ligand might not enter into or optimize sale or licensing or similar transactions which could result in CVR payments.

 

   

In no event shall declining to effect a licensing agreement and/or sale agreement and/or similar agreement on terms and conditions that create a commercially unreasonable risk of liability on the part of Ligand or the surviving corporation be deemed not to satisfy the “in good faith and with commercial reasonableness” standard.

 

   

In no event shall declining to effect a sale or transfer of the Roche Agreement rights (including royalty rights, milestone payment rights or rights to all or any portion of a drug candidate or technology licensed pursuant to the Roche Agreement) or any other decision to retain existing rights under the Roche Agreement be deemed not to satisfy the “in good faith and with commercial reasonableness” standard under the Roche CVR agreement.

 

   

No payments will be made in connection with a CVR payment trigger event if the trigger event occurs after the outside date as defined in the CVR agreement. Accordingly, the CVRs may ultimately have no value, even if a licensing agreement and/or sale agreement and/or similar agreement occurs.

 

22


Table of Contents
   

If Ligand develops and commercializes a drug candidate on its own, there will be no licensing agreement and/or sale agreement and/or similar agreement, and therefore there will be no CVR payment, even if the drug is successful.

 

   

For all the reasons that drug development programs might not succeed, Ligand might not be able to bring an applicable drug development program to the point where it can be made the subject of a licensing agreement and/or sale agreement and/or similar agreement, and in such event there will be no CVR payment.

CVR holders must rely on the Stockholders’ Representative to assert CVR holders’ rights, and the Stockholders’ Representative can enter into amendments of the CVR agreements which would adversely affect a CVR holder.

CVR holders will be required to rely, for the monitoring and enforcement and/or settlement of their rights under the CVR agreements and the CVRs, on an appointed Stockholders’ Representative. The initial appointed Stockholders’ Representative is David F. Hale, who currently is serving as Executive Chairman and Acting Principal Executive Officer of Metabasis.

To the extent permitted by applicable law, in no event shall any holders of CVRs (as opposed to the Stockholders’ Representative) or any former stockholders of Metabasis (as opposed to the Stockholders’ Representative) have, after the effective time of the merger, any power or right to commence or join in any claim (presented formally to a judicial or quasi-judicial governmental entity), lawsuit, court action, suit, arbitration or other judicial or administrative proceeding based on or arising out of any CVR agreement or the merger agreement.

Ligand may, with the written consent of the Stockholders’ Representative and the holders of at least 20% of the applicable series of CVRs, enter into one or more amendments to any CVR agreement for the purpose of adding, eliminating or changing any provision of the applicable CVR agreement, even if the addition, elimination or change is in any way adverse to the rights of CVR holders. Any such amendment shall be binding on all CVR holders.

The Stockholders’ Representative may be hindered by financial constraints.

To perform his functions with optimal effectiveness, the Stockholders’ Representative might find it necessary to engage outside professionals or incur other expenses. Although the merger agreement and CVR agreements provide a fund for his expenses and compensation, the fund is limited in amount and he has no obligation to spend his personal resources if the fund is exhausted. The fund will receive $150,000 upon the closing of the merger and will thereafter be augmented (to the extent such augmentation would not increase the fund to over $300,000) by 1% of any amounts that are otherwise payable to CVR holders under any of the CVR agreements or that are subtracted from such amounts to make or reimburse payments related to certain contingent liabilities.

The fund must also bear the expense of the Stockholders’ Representative’s compensation for serving as such, which is $45,000 per year.

Amounts payable under the CVRs can be reduced by up to $2.65 million to pay or reimburse payment of certain contingent liabilities.

Metabasis has contingent liabilities of up to $1.5 million to its landlord ARE-SD Region No. 24, LLC. In July 2009, Metabasis entered into an agreement to terminate as of January 2, 2010 its lease for its corporate headquarters facility, and to sell its laboratory and office equipment, in exchange for consideration including contingent cash payments to be made based upon gross revenues or proceeds actually received by Metabasis pursuant to licenses, collaboration arrangements or sales of Metabasis’ existing pipeline of therapeutic programs

 

23


Table of Contents

by September 30, 2010. ARE-SD would be entitled to receive contingent liability payments equal to 35% of such gross revenues or proceeds actually received by Metabasis, up to a total cash payment of $1.5 million to ARE-SD.

Metabasis also has contingent liabilities of up to an aggregate of approximately $1.15 million for contingent cash severance payments to the employees who were terminated in Metabasis’ May 2009 reduction in force. These contingent severance payments are triggered if Metabasis receives at least $10 million in the aggregate from the sale or license of its intellectual property assets, including the receipt of milestone payments from Roche, before May 26, 2010. If Metabasis receives $10 million, before May 26, 2010 from the sale or license of its intellectual property assets then Metabasis has the obligation to pay an amount equal to 46 days’ salary at the respective employee’s salary rate at the time of termination. If the sale or license of intellectual property results in proceeds of $20 million before May 26, 2010, Metabasis has the obligation to make additional cash payments equal to a certain additional number of days’ salary (depending on the employee) at the employee’s respective salary rate at the time of termination.

In general, events which would give rise to payments of the contingent liabilities described in the two preceding paragraphs, or the contingent liability payments, would also give rise to payments under one of the CVRs. Each CVR agreement provides that any contingent liability payments are to be satisfied first from amounts otherwise payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such payment event, but in some instances the full amount payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such payment event will be less than the contingent liability payments owing in respect of such payment event.

In the event of such a shortfall, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such payment event will be paid by Ligand directly to the beneficiaries of the contingent liability payments rather than to or for the benefit of the holders of the CVRs under the applicable CVR agreement, and the remainder of the contingent liability payments owing in respect of such payment event, or the excess, shall be paid by Ligand directly to the beneficiaries of the contingent liability payments. Then, then upon the next payment event under any of the CVR agreements (even if not the same CVR agreement in connection with which the excess was paid), Ligand shall withhold from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such (new) payment event, and shall keep for Ligand’s own account to reimburse Ligand for having paid the excess, an amount equal to 100% of the excess (or, if less, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such (new) payment event). If Ligand is not thereby reimbursed for the entire excess, the shortfall shall be rolled forward to be satisfied in the same manner by withholding from any amount otherwise payable for the benefit of the holders of CVRs in respect of the next-to-occur payment event under any of the CVR agreements (even if not the same CVR agreement in connection with which the excess was paid or in connection with which the excess was partially satisfied).

As noted, it is possible that an excess that arises because of a CVR payment triggering event that triggers payments under only one type of CVRs may be satisfied from a next-to-occur payment(s) arising under another type or types of CVRs. In such a case, the CVRs which satisfy the excess will have no recourse against the CVRs which created the excess, even if other payment events and payments later occur under the CVRs which created the excess.

It is also true that because reductions to satisfy up to the entire amount of all contingent liability payments ever payable may be made entirely or disproportionately from early-occurring payment events arising under one or more particular CVR agreements, holders of that type of CVRs would be disadvantaged in comparison to the holders of other types of CVRs if the other types of CVRs have later-occurring payment events. Payments under such other types of CVRs would not have to be reduced to satisfy contingent liability payments, if all contingent liability payments ever payable have already been satisfied.

Uncertainty regarding the merger and the effects of the merger could cause each company’s licensors, collaborators, suppliers or other strategic partners to delay or defer decisions, which could increase costs of the ongoing business for Ligand and/or Metabasis.

Ligand’s and Metabasis’ strategy for developing and commercializing many of their potential products includes entering into agreements with licensors, collaborators, suppliers and other strategic partners. These partners, in response to the announcement of the merger, may delay or defer decisions regarding their business relationships with each company, which could increase costs for the business of the subject company and delay, interrupt or terminate the collaborate research, development and commercialization of certain potential products, regardless of whether the merger is ultimately completed. Under specified circumstances, these partners may also terminate their agreements with each company. Any such delay, interruption or termination of the combined company’s relationship with any of these partners could materially harm the combined company’s business and financial condition, and frustrate any commercialization efforts for its product candidates.

The merger is subject to closing conditions that could result in the completion of the merger being delayed or not consummated, which could negatively impact Ligand’s and/or Metabasis’ stock price and future business and operations.

Completion of the merger is conditioned upon Ligand and Metabasis satisfying closing conditions, including adoption of the merger agreement by Metabasis’ stockholders, all as set forth in the merger agreement. See the section entitled “Certain Terms of the Merger Agreement—Conditions to the Merger” beginning on page 88 for a discussion of the conditions to the completion of the merger. The required conditions to closing may not be satisfied in a timely manner, if at all, or, if permissible, waived, and the merger may not be consummated. Failure to consummate the merger could negatively impact Ligand’s and/or Metabasis’ stock price, future business and operations, and financial condition. Any delay in the consummation of the merger or any uncertainty about the consummation of the merger may adversely affect the future business, growth, revenue and results of operations of either or both of the companies.

If the merger is not completed for any reason, the ongoing business of Ligand and Metabasis may be adversely affected and will be subject to a number of risks, including:

 

   

Metabasis may be required, under some circumstances, to pay Ligand a termination fee of up to $400,000. See “Certain Terms of the Merger Agreement—Termination Fee” beginning on page 92 of this proxy statement/prospectus;

 

   

the diversion of management’s attention, the reduction in capital spending and acquisitions, the suspension of planned hiring and other affirmative and negative covenants in the merger agreement restricting each company’s business;

 

   

failure to pursue other beneficial opportunities as a result of the focus of management of each of the companies on the merger, without realizing any of the anticipated benefits of the merger;

 

   

the market price of Ligand common stock or Metabasis common stock may decline to the extent that the current market price reflects a market assumption that the merger will be completed;

 

   

Ligand and Metabasis may experience negative reactions to the termination of the merger from licensors, collaborators, suppliers, or other strategic partners; and

 

   

Ligand’s and Metabasis’ costs incurred related to the merger, such as legal and accounting fees, must be paid even if the merger is not completed.

If the merger agreement is terminated and Metabasis’ board of directors seeks another merger or business combination, Metabasis stockholders cannot be certain that Metabasis will be able to find a party willing to pay a price equivalent to or more attractive than the price Ligand has agreed to pay in the merger.

 

25


Table of Contents

Metabasis’ executive officers and directors have interests different from your interests that may influence them to support or approve the merger.

In considering the recommendation of the Metabasis board of directors to adopt the merger agreement, Metabasis stockholders should recognize that Metabasis’ executive officers and directors have interests that differ from those of Metabasis’ and Ligand’s stockholders because of employment arrangements, severance arrangements, change of control agreements, indemnification and liability insurance and other reasons. These reasons are described in the section entitled “The Merger Agreement—Interests of Metabasis’ Executive Officers and Directors in the Merger.”

The merger agreement limits Metabasis’ ability to pursue alternatives to the merger.

Metabasis has agreed that it shall not, and shall not authorize or permit Metabasis’ and Metabasis’ subsidiaries’, or any of their respective directors, officers, employees, investment bankers, attorneys and other agents or representatives to, directly or indirectly, not to:

 

   

solicit, initiate, knowingly encourage or knowingly induce the making, submission or announcement of an acquisition proposal;

 

   

furnish any non-public information relating to Metabasis in response to or in connection with an acquisition proposal;

 

   

participate or engage in discussions or negotiations with respect to an acquisition proposal; or

 

   

approve, endorse or recommend to the stockholders of Metabasis any acquisition proposal.

Under the terms of the merger agreement, Metabasis has agreed to immediately cease and cause to be terminated any active discussions with any party (other than Ligand) that relate to any acquisition proposal.

Under certain circumstances, the merger agreement also provides that Metabasis will be required to pay a termination fee of up to $400,000 to Ligand upon termination of the merger agreement. These provisions might discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of Metabasis from considering or proposing an acquisition even if it were prepared to pay consideration with a higher value than that proposed in the merger, or might result in a potential competing acquirer proposing to pay consideration with a lower value to acquire Metabasis than it might otherwise have proposed to pay.

The United States federal income tax treatment of the receipt of CVRs in the merger is unclear.

There is substantial uncertainty as to the tax treatment of the receipt of CVRs in the merger. The receipt of the CVRs as part of the merger consideration may be treated as a “closed transaction” or an “open transaction” for United States federal income tax purposes, which affects the amount of gain, if any, or loss that may be recognized at the time of consummation of the merger. Ligand’s current intention is to take steps consistent with “closed transaction” tax treatment. See “The Merger—Material United States Federal Income Tax Consequences of the Merger” beginning on page 69 of this proxy statement/prospectus for a more detailed discussion of the United States federal income tax treatment of the receipt of CVRs in the merger.

Risks Related to Ligand

While Metabasis stockholders are not receiving Ligand common stock or other Ligand equity securities in the merger, the amount ultimately received by the Metabasis stockholders from the CVRs could be diminished in the event of difficulties in the business, financial condition or results of operations of Ligand. If any of the events, contingencies, circumstances or conditions described in the following risks actually occur, Ligand’s business, financial condition or results of operations could be seriously harmed.

Table of Contents

Ligand is substantially dependent on AVINZA and PROMACTA royalties for its revenues.

King Pharmaceuticals, Inc., or King, is obligated to pay Ligand royalties based on its sales of AVINZA and GlaxoSmithKline, or GSK, is obligated to pay Ligand royalties on its sales of PROMACTA. These royalties represent and will for some time represent substantially all of Ligand’s ongoing revenue. Although Ligand may also receive royalties and milestones from its partners in various past and future collaborations, the amount of revenue from such royalties and milestones is unknown and highly uncertain. As a result, any setback that may occur with respect to AVINZA or PROMACTA could significantly impair Ligand’s operating results and/or reduce the market price of Ligand’s stock. Setbacks could include problems with shipping, distribution, manufacturing, product safety, marketing, government licenses and approvals, intellectual property rights, competition with existing or new products and physician or patient acceptance of the products, as well as higher than expected total rebates, returns or discounts.

King and GSK’s sales efforts for AVINZA and PROMACTA, respectively, could be affected by a number of factors and decisions regarding their organizations, operations, and activities as well as events both related and unrelated to AVINZA or PROMACTA, including sales force reorganizations and lower than expected sales calls and prescription volumes. AVINZA and PROMACTA could also face stiffer competition from existing or future products. The negative impact on the sales of AVINZA or PROMACTA will negatively affect Ligand’s royalties, revenues and earnings.

Sales of AVINZA and PROMACTA may also be negatively impacted by higher than expected discounts (especially pharmacy benefit management/group purchasing organization rebates and Medicaid rebates, which can be substantial), returns and chargebacks and/or slower than expected market penetration. Other setbacks that AVINZA could face in the sustained-release opioid market include abuse issues and the inability to obtain sufficient quotas of morphine from the Drug Enforcement Agency to support production requirements.

AVINZA or PROMACTA could also face regulatory action and product safety issues. For example, the FDA previously requested expanded warnings on the AVINZA label to alert doctors and patients to the dangers of using AVINZA with alcohol. Changes were subsequently made to the label. The FDA also requested clinical studies to investigate the risks associated with taking AVINZA with alcohol. Any additional warnings, studies and any further regulatory action could have significant adverse effects on AVINZA sales.

On September 10, 2007, King reported that Actavis Elizabeth L.L.C., or Actavis, an affiliate of Actavis Group, hf., a manufacturer of generic pharmaceutical products headquartered in Iceland, had filed with the FDA an Abbreviated New Drug Application, or ANDA, with a Paragraph IV Certification pertaining to AVINZA, the rights to which were acquired by King from Ligand in February 2007. According to the report, Actavis’ Paragraph IV Certification sets forth allegations that U.S. Patent No. 6,066,339, or the 339 patent, which pertains to AVINZA, and which is listed in the FDA’s Approved Drug Products With Therapeutic Equivalence Evaluations, will not be infringed by Actavis’ manufacture, use, or sale of the product for which the ANDA was submitted. The expiration date for this patent is November 2017. King, King Pharmaceuticals Research and Development, Inc., Elan Corporation, plc and Elan Pharma International Ltd. jointly filed suit in federal district court in New Jersey on October 18, 2007 against Actavis, Inc. and Actavis Elizabeth L.L.C. for patent infringement under the 339 patent. The lawsuit seeks a judgment that would, among other things, prevent Actavis from commercializing its proposed morphine product until after expiration of the 339 patent.

On July 21, 2009, King, King Pharmaceuticals Research and Development, Inc., Elan Corporation, plc and Elan Pharma International Ltd. jointly filed suit in federal district court in New Jersey against Sandoz Inc., or Sandoz, for patent infringement under the 339 patent. According to the complaint, Sandoz filed an ANDA for morphine sulfate extended release capsules and, in connection with the ANDA filing, Sandoz provided written certification to the FDA alleging that the claims of the 339 patent are invalid, unenforceable and/or will not be infringed by the manufacture, use or sale of Sandoz’s proposed morphine product. Similar to the lawsuit against Actavis, this lawsuit seeks a judgment that would, among other things, prevent Sandoz from commercializing its proposed morphine product until after expiration of the 339 patent.

Table of Contents

AVINZA was licensed from Elan Corporation, or Elan, which is its sole manufacturer. Any problems with Elan’s manufacturing operations or capacity could reduce sales of AVINZA, as could any licensing or other contract disputes with Elan, raw materials suppliers, or others.

Further, pursuant to the agreement with King, beginning in 2009 Ligand is no longer entitled to receive AVINZA royalties on a quarterly basis, but will collect royalties on an annual basis, which may adversely impact Ligand’s cash flows.

Ligand’s product candidates face significant regulatory hurdles which could delay or prevent sales.

Before Ligand obtains the approvals necessary to sell any of its potential products, it must show through preclinical studies and human testing that the product is safe and effective. Ligand and its partners have a number of products moving toward or currently awaiting regulatory action, including bazedoxifene, lasofoxifene, PS433540 and PS031291. Failure to show any product’s safety and effectiveness could delay or prevent regulatory approval of a product and could adversely affect Ligand’s business. The clinical trials process is complex and uncertain. For example, the results of preclinical studies and initial clinical trials may not necessarily predict the results from later large-scale clinical trials. In addition, clinical trials may not demonstrate a product’s safety and effectiveness to the satisfaction of the regulatory authorities. Recently, a number of companies have suffered significant setbacks in advanced clinical trials or in seeking regulatory approvals, despite promising results in earlier trials. The FDA may also require additional clinical trials after regulatory approvals are received. Such additional trials may be expensive and time-consuming, and failure to successfully conduct those trials could jeopardize continued commercialization of a product.

The rate at which Ligand and its collaborative partners complete clinical trials depends on many factors, including, but not limited to, its ability to obtain adequate supplies of the products to be tested and patient enrollment. Patient enrollment is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites and the eligibility criteria for the trial. Delays in patient enrollment for Ligand’s trials may result in increased costs and longer development times. For example, the trial entitled “Eltrombopag To Reduce The Need For Platelet Transfusion In Subjects With Chronic Liver Disease And Thrombocytopenia Undergoing Elective Invasive Procedures (ELEVATE)” was suspended in October 2009 in accordance with an Independent Data Monitoring Committee Recommendation. In addition, Ligand’s collaborative partners have rights to control product development and clinical programs for products developed under the collaborations. As a result, these collaborative partners may conduct these programs more slowly or in a different manner than expected. Moreover, even if clinical trials are completed, Ligand or its collaborative partners still may not apply for FDA approval in a timely manner or the FDA still may not grant approval.

Ligand relies heavily on collaborative relationships, and any disputes or litigation with its collaborative partners or termination or breach of any of the related agreements could reduce the financial resources available to it, including milestone payments and future royalty revenues.

Ligand’s strategy for developing and commercializing many of its potential products, including products aimed at larger markets, includes entering into collaborations with corporate partners and others. These collaborations have provided Ligand with funding and research and development resources for potential products for the treatment of a variety of diseases. These agreements also give Ligand’s collaborative partners significant discretion when deciding whether or not to pursue any development program. Ligand’s existing collaborations may not continue or be successful, and Ligand may be unable to enter into future collaborative arrangements to develop and commercialize its product candidates.

In addition, Ligand’s collaborators may develop drugs, either alone or with others that compete with the types of drugs they are developing with Ligand. This would result in increased competition for Ligand’s programs. If products are approved for marketing under Ligand’s collaborative programs, revenues it receives will depend on the manufacturing, marketing and sales efforts of its collaborative partners, who generally retain commercialization rights under the collaborative agreements. Generally, Ligand’s current collaborative partners

 

28


Table of Contents

also have the right to terminate their collaborations under specified circumstances. If any of Ligand’s collaborative partners breach or terminate their agreements with Ligand or otherwise fail to conduct their collaborative activities successfully, Ligand’s product development under these agreements will be delayed or terminated. Disputes or litigation may also arise with Ligand’s collaborators, including disputes or litigation over ownership rights to intellectual property, know-how or technologies developed with its collaborators. Such disputes or litigation could adversely affect Ligand’s rights to one or more of its product candidates, including its PS433540, PS031291 and LGD-4033 and small-molecule EPO mimetic compounds. Any such dispute or litigation could delay, interrupt or terminate the collaborative research, development and commercialization of certain potential products, create uncertainty as to ownership rights of intellectual property, or could result in litigation or arbitration. The occurrence of any of these problems could be time-consuming and expensive and could adversely affect Ligand’s business.

If Ligand consumes cash more quickly than expected, and if it is unable to raise additional capital, it may be forced to curtail operations.

Ligand’s operations have consumed substantial amounts of cash since inception. Clinical and preclinical development of drug candidates is a long, expensive and uncertain process. Also, Ligand may acquire companies, businesses or products and the consummation of such acquisitions may consume additional cash. For example, as part of the consideration for Ligand’s recent acquisition of Pharmacopeia, Inc., or Pharmacopeia, Ligand distributed approximately $9.3 million in cash to Pharmacopeia stockholders. Security holders of Pharmacopeia also received contingent value rights under which Ligand could be required to make an aggregate cash payment of $15.0 million to such security holders under certain circumstances. Ligand may also under certain circumstances be required to make cash payments to former stockholders of Neurogen Corporation pursuant to contingent value rights, if Ligand’s pending acquisition of Neurogen Corporation is completed.

Ligand believes that its capital resources, including its currently available cash, cash equivalents, and short-term investments as well as its current and future royalty revenues, will be adequate to fund its operations at their current levels at least for the next twelve months. However, changes may occur that would cause Ligand to consume available capital resources before that time. Examples of relevant potential changes that could impact Ligand’s capital resources include:

 

   

the costs associated with Ligand’s drug research and development activities, and additional costs Ligand may incur if its development programs are delayed or are more expensive to implement than Ligand currently anticipates;

 

   

changes in existing collaborative relationships, including the funding Ligand receives in connection with those relationships;

 

   

the progress of Ligand’s milestone and royalty producing activities;

 

   

acquisitions of other businesses or technologies;

 

   

the termination of Ligand’s lease agreements;

 

   

the purchase of additional capital equipment;

 

   

cash payments or refunds Ligand may be required to make pursuant to certain agreements with third parties;

 

   

competing technological and market developments; and

 

   

the cost of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights, and the outcome of related litigation.

Additional capital may not be available on favorable terms, or at all. If additional capital is not available, Ligand may be required to curtail operations significantly or to obtain funds by entering into arrangements with partners or other third parties that may require Ligand to relinquish rights to certain of its technologies, products or potential markets that it would not otherwise relinquish.

If, as the result of a merger, or otherwise, Ligand’s collaborative partners were to change their strategy or the focus of their development and commercialization efforts with respect to Ligand’s alliance products, the success of Ligand’s alliance products could be adversely affected.

Ligand’s collaborative partners may change the focus of their development and commercialization efforts as the result of a merger. Pharmaceutical and biotechnology companies have historically re-evaluated their priorities from time to time, including following mergers and consolidations which are common in these industries, and two of Ligand’s collaborative partners have recently entered into merger agreements. In October 2009, Wyeth, a collaborative partner of Ligand, and Pfizer Inc. announced that Pfizer Inc. had completed its acquisition of Wyeth in a cash and stock transaction. Furthermore, in March 2009, Schering-Plough Corporation, another of Ligand’s collaborative partners, and Merck & Co., Inc., or Merck, announced that their boards of directors unanimously approved a definitive merger agreement pursuant to which Merck and Schering-Plough will combine, under the name Merck, in a stock and cash transaction. As a result of the consummation of these mergers Ligand’s collaborative partners may develop and commercialize, either alone or with others, products and services that are similar to or competitive with Ligand’s alliance products. Furthermore, the ability of Ligand’s alliance products to reach their potential could be limited if its collaborative partners reduce or fail to increase spending related to such products as a result of these mergers.

If Ligand’s collaborative partners terminate their collaborations with Ligand or do not commit sufficient resources to the development, manufacture, marketing or distribution of Ligand’s alliance products, Ligand could be required to devote additional resources to its alliance products, seek new collaborative partners or abandon such alliance products, all of which could have an adverse effect on Ligand’s business.

Third party intellectual property may prevent Ligand or its partners from developing Ligand’s potential products and Ligand may owe a portion of any payments it receives from its collaborative partners to one or more third parties.

Ligand’s success will depend on its ability and the ability of its collaborative partners to avoid infringing the proprietary rights of others, both in the United States and in foreign countries. In addition, disputes with licensors under Ligand’s license agreements may arise which could result in additional financial liability or loss of important technology and potential products and related revenue, if any. Further, the manufacture, use or sale of Ligand’s potential products or its collaborative partners’ products or potential products may infringe the patent rights of others. This could impact AVINZA, PROMACTA, bazedoxifene, lasofoxifene, LGD-4665, PS433540, PS031291 and any other products or potential products.

Several drug companies and research and academic institutions have developed technologies, filed patent applications or received patents for technologies that may be related to Ligand’s business. Others have filed patent applications and received patents that conflict with patents or patent applications Ligand has licensed for Ligand’s use, either by claiming the same methods or compounds or by claiming methods or compounds that could dominate those licensed to Ligand. In addition, Ligand may not be aware of all patents or patent applications that may impact its ability to make, use or sell any of its potential products. For example, US patent applications may be kept confidential while pending in the United States Patent and Trademark Office and patent applications filed in foreign countries are often first published six months or more after filing.

On March 4, 2008, The Rockefeller University, or Rockefeller, filed suit in the United States District Court for the Southern District of New York, against Ligand alleging, among other things, a breach by Ligand of its September 30, 1992 license agreement with Rockefeller, as well as other causes of action for unjust enrichment, quantum meruit, specific performance to perform an audit and declaratory relief. In February 2009 Ligand reached a settlement with Rockefeller whereby the parties resolved all disputes that have arisen between them, including Rockefeller’s primary claim relating to the development of PROMACTA as well as Ligand’s counterclaims.

Other possible disagreements or litigation with Ligand’s collaborative partners could delay Ligand’s ability and the ability of its collaborative partners to achieve milestones or Ligand’s receipt of other payments. In addition, other possible disagreements or litigation could delay, interrupt or terminate the research, development and commercialization of certain potential products being developed by either Ligand’s collaborative partners or by Ligand. The occurrence of any of the foregoing problems could be time-consuming and expensive and could adversely affect Ligand’s business.

Third parties have not directly threatened an action or claim against Ligand, although it does periodically receive other communications or has other conversations with the owners of other patents or other intellectual property. If others obtain patents with conflicting claims, Ligand may be required to obtain licenses to those patents or to develop or obtain alternative technology. Ligand may not be able to obtain any such licenses on acceptable terms, or at all. Any failure to obtain such licenses could delay or prevent Ligand from pursuing the development or commercialization of its potential products.

In general, litigation claims can be expensive and time consuming to bring or defend against and could result in settlements or damages that could significantly impact Ligand’s results of operations and financial condition. Ligand cannot predict or determine the outcome of these matters or reasonably estimate the amount or range of amounts of any fines or penalties that might result from a settlement or an adverse outcome. However, a settlement or an adverse outcome could have a material adverse effect on Ligand’s financial position, liquidity and results of operations.

Ligand may not be able to hire and/or retain key employees.

If Ligand is unable to hire and/or retain key employees, it may not have sufficient resources to successfully manage its assets or its business, and it may not be able to perform its obligations under various contracts and commitments. Furthermore, there can be no assurance that Ligand will be able to retain all of Pharmacopeia’s key management and scientific personnel. If Ligand fails to retain such key employees, it may not realize the anticipated benefits of the Pharmacopeia merger. Either of these could have substantial negative impacts on Ligand’s business and its stock price.

Ligand’s stock price has been volatile and could experience a sudden decline in value.

Ligand’s common stock has experienced significant price and volume fluctuations and may continue to experience volatility in the future. As a result, stockholders may not be able to sell their shares quickly or at the latest market price if trading in Ligand’s stock is not active or the volume is low. Many factors may have a significant impact on the market price of Ligand’s common stock, including, but not limited to, the following factors: results of or delays in Ligand’s preclinical studies and clinical trials; the success of Ligand’s collaboration agreements; publicity regarding actual or potential medical results relating to products under development by Ligand or others; announcements of technological innovations or new commercial products by Ligand or others; developments in patent or other proprietary rights by Ligand or others; comments or opinions by securities analysts or major stockholders; future sales of Ligand’s common stock by existing stockholders; regulatory developments or changes in regulatory guidance; litigation or threats of litigation; economic and other external factors or other disaster or crises; the departure of any of Ligand’s officers, directors or key employees; period-to-period fluctuations in financial results; and limited daily trading volume.

The Financial Industry Regulatory Authority, or FINRA (formerly the National Association of Securities Dealers, Inc.), NASDAQ and the SEC have adopted certain new rules. If Ligand were unable to continue to comply with the new rules, it could be delisted from trading on Nasdaq, and thereafter trading in its common stock, if any, would be conducted through the over-the-counter market or on the Electronic Bulletin Board of FINRA. As a consequence of such delisting, an investor would likely find it more difficult to dispose of, or to obtain quotations as to the price of, Ligand’s common stock. Delisting of Ligand’s common stock could also result in lower prices per share of its common stock than would otherwise prevail.

Ligand may not be successful in entering into additional out-license agreements on favorable terms, which may adversely affect Ligand’s liquidity or require it to alter development plans on its products.

Ligand has entered into several out-licensing agreements for the development and commercialization of its products. Although Ligand expends considerable resources on internal research and development for its proprietary programs, it may not be successful in entering into additional out-licensing agreements under favorable terms due to several factors including:

 

   

the difficulty in creating valuable product candidates that target large market opportunities;

 

   

research and spending priorities of potential licensing partners;

 

   

willingness of and the resources available to pharmaceutical and biotechnology companies to in-license product candidates for their clinical pipelines; or

 

   

differences of opinion with potential partners on the valuation of products Ligand is seeking to out-license.

The inability to enter into out-licensing agreements under favorable terms and to earn milestone payments, license fees and/or upfront fees may adversely affect Ligand’s liquidity and may force Ligand to curtail or delay development of some or all of its proprietary programs, which in turn may harm its business and the value of its stock.

Ligand’s product development involves a number of uncertainties, and Ligand may never generate sufficient collaborative payments and royalties from the development of products to become profitable.

Ligand was founded in 1987. Ligand has incurred significant losses since its inception. As of September 30, 2009, Ligand’s accumulated deficit was $684.6 million.

Most of Ligand’s products in development will require extensive additional development, including preclinical testing and human studies, as well as regulatory approvals, before they can be marketed. Ligand cannot predict if or when any of the products it is developing or those being developed with its partners will be approved for marketing. There are many reasons why Ligand or its collaborative partners may fail in their efforts to develop their potential products, including the possibility that: preclinical testing or human studies may show that their potential products are ineffective or cause harmful side effects; the products may fail to receive necessary regulatory approvals from the FDA or foreign authorities in a timely manner, or at all; the products, if approved, may not be produced in commercial quantities or at reasonable costs; the products, if approved, may not achieve commercial acceptance; regulatory or governmental authorities may apply restrictions to the products, which could adversely affect their commercial success; or the proprietary rights of other parties may prevent Ligand or its partners from marketing the products.

Any product development failures for these or other reasons, whether with Ligand’s products or its partners’ products, may reduce Ligand’s expected revenues, profits, and stock price.

Any future material weaknesses or deficiencies in Ligand’s internal control over financial reporting could harm stockholder and business confidence on its financial reporting, its ability to obtain financing and other aspects of its business.

While no material weaknesses were identified as of September 30, 2009, Ligand cannot assure you that material weaknesses will not be identified in future periods. The existence of one or more material weakness or significant deficiency could result in errors in Ligand’s consolidated financial statements. Substantial costs and resources may be required to rectify any internal control deficiencies. If Ligand fails to achieve and maintain the adequacy of its internal controls in accordance with applicable standards, it may be unable to conclude on an ongoing basis that it has effective internal controls over financial reporting. If Ligand cannot produce reliable financial reports, its business and financial condition could be harmed, investors could lose confidence in its

 

32


Table of Contents

reported financial information, or the market price of its stock could decline significantly. In addition, Ligand’s ability to obtain additional financing to operate and expand its business, or obtain additional financing on favorable terms, could be materially and adversely affected, which, in turn, could materially and adversely affect its business, its financial condition and the market value of its securities. Moreover, Ligand’s reputation with customers, lenders, investors, securities analysts and others may be adversely affected.

Challenges to or failure to secure patents and other proprietary rights may significantly hurt Ligand’s business.

Ligand’s success will depend on its ability and the ability of its licensors to obtain and maintain patents and proprietary rights for its potential products both in the United States and in foreign countries. Patents may not be issued from any of these applications currently on file, or, if issued, may not provide sufficient protection. Ligand’s patent position, like that of many biotechnology and pharmaceutical companies, is uncertain and involves complex legal and technical questions for which important legal principles are unresolved. Ligand may not develop or obtain rights to products or processes that are patentable. Even if Ligand does obtain patents, such patents may not adequately protect the technology Ligand owns or has licensed. In addition, others may challenge, seek to invalidate, infringe or circumvent any patents Ligand owns or licenses and rights Ligand receives under those patents may not provide competitive advantages to Ligand.

Any conflicts resulting from the patent rights of others could significantly reduce the coverage of Ligand’s patents and limit its ability to obtain meaningful patent protection. Ligand has had and will continue to have discussions with its current and potential collaborative partners regarding the scope and validity of its patents and other proprietary rights. If a collaborative partner or other party successfully establishes that Ligand’s patent rights are invalid, Ligand may not be able to continue its existing collaborations beyond their expiration. Any determination that Ligand’s patent rights are invalid also could encourage its collaborative partners to seek early termination of their agreements. Such invalidation could adversely affect Ligand’s ability to enter into new collaborations.

Ligand may also need to initiate litigation, which could be time-consuming and expensive, to enforce its proprietary rights or to determine the scope and validity of others’ rights. If litigation occurs, a court may find Ligand’s patents or those of its licensors invalid or may find that Ligand has infringed on a competitor’s rights. In addition, if any of Ligand’s competitors has filed patent applications in the United States which claim technology Ligand also has invented, the United States Patent and Trademark Office may require Ligand to participate in expensive interference proceedings to determine who has the right to a patent for the technology.

Ligand also relies on unpatented trade secrets and know-how to protect and maintain its competitive position. Ligand requires its employees, consultants, collaborative partners and others to sign confidentiality agreements when they begin their relationship with Ligand. These agreements may be breached, and Ligand may not have adequate remedies for any breach. In addition, Ligand’s competitors may independently discover its trade secrets.

Ligand will have continuing obligations to indemnify the buyers of its commercial product lines, and may be subject to other liabilities related to the sale of Ligand’s commercial product lines.

Ligand has agreed to indemnify Eisai, the purchaser of its Oncology product line, for damages suffered by Eisai arising from any breach of Ligand’s representations, warranties, covenants or obligations in the asset purchase agreement. Ligand’s obligation to indemnify Eisai extends beyond the closing of the sale of its Oncology product line in October 2006 up to, in some cases, 36 months and, in other cases, until the expiration of the applicable statute of limitations. In a few instances, Ligand’s obligation to indemnify Eisai survives in perpetuity.

Under the asset purchase agreements, Ligand’s exposure for any indemnification claim brought by Eisai is limited to $30.0 million. However, in certain matters, Ligand’s indemnification obligation is not subject to the

 

33


Table of Contents

foregoing limits on liability. For example, Ligand is obligated to indemnify King, without limitation, for all liabilities arising under certain agreements with Catalent Pharma Solutions related to the manufacture of AVINZA. Similarly, Ligand is obligated to indemnify Eisai, without limitation, for all liabilities related to certain claims regarding promotional materials for the ONTAK and Targretin drug products. Ligand cannot predict the liabilities that may arise as a result of these matters. Any claims related to Ligand’s indemnification obligations to Eisai could materially and adversely affect Ligand’s financial condition.

As previously disclosed, in connection with the AVINZA sale transaction, King assumed Ligand’s obligation to make payments to Organon based on net sales of AVINZA (the fair value of which was $57.3 million as of September 30, 2009). As Organon did not consent to the legal assignment of the co-promote termination obligation from Ligand to King, Ligand remains liable to Organon in the event King defaults on this obligation. Any requirement to pay a material amount to Organon, could adversely affect Ligand’s business and the price of its securities.

The sale of Ligand’s commercial product lines does not relieve it of exposure to product liability risks on products it sold before divesting these product lines. For example, such products may need to be recalled to address regulatory issues. A successful product liability claim or series of claims brought against Ligand could result in payment of significant amounts of money and divert management’s attention from running Ligand’s business.

Ligand believes that it carries reasonably adequate insurance for product liability claims. However, Ligand may not be able to maintain its insurance on commercially reasonable terms, or its insurance may not provide adequate protection in the case of a product liability claim. To the extent that product liability insurance, if available, does not cover potential claims, Ligand will be required to self-insure the risks associated with such claims.

If Ligand’s partners do not reach the market with Ligand’s alliance products before Ligand’s competitors offer products for the same or similar uses, or if Ligand’s partners are not effective in marketing Ligand’s alliance products, Ligand’s revenues from product sales, if any, will be reduced.

Ligand faces intense competition in its development activities. Ligand’s competitors might succeed in obtaining regulatory approval for competitive products more rapidly than Ligand’s partners can for Ligand’s products. In addition, competitors might develop technologies and products that are less expensive and perceived to be safer or more effective than those being developed by Ligand or its partners, which could impair Ligand’s product development and render its technology obsolete.

Ligand uses hazardous materials, which may expose it to significant liability.

In connection with Ligand’s research and development activities, Ligand handles hazardous materials, chemicals and various radioactive compounds. To properly dispose of these hazardous materials in compliance with environmental regulations, Ligand is required to contract with third parties. Ligand believes that it carries reasonably adequate insurance for toxic tort claims. However, Ligand cannot eliminate the risk or predict the exposure of accidental contamination or injury from the handling and disposing of hazardous materials, whether by Ligand or its third-party contractors. Any accident in the handling and disposing of hazardous materials may expose Ligand to significant liability.

Ligand’s shareholder rights plan and charter documents may hinder or prevent change of control transactions.

Ligand’s shareholder rights plan and provisions contained in its certificate of incorporation and bylaws may discourage transactions involving an actual or potential change in Ligand’s ownership. In addition, Ligand’s board of directors may issue shares of preferred stock without any further action by the stockholders. Such

 

34


Table of Contents

restrictions and issuances may have the effect of delaying or preventing a change in Ligand’s ownership. If changes in Ligand’s ownership are discouraged, delayed or prevented, it would be more difficult for Ligand’s current board of directors to be removed and replaced, even if Ligand’s stockholders believe that such actions are in the best interests of Ligand and its stockholders.

Ligand may lose some or all of the value of some of its short term investments.

Ligand engages one or more third parties to manage some of its cash consistent with an investment policy that allows a range of investments and maturities. The investments are intended to maintain safety of principal while providing liquidity adequate to meet projected cash requirements. Risks of principal loss are to be minimized through diversified short and medium term investments of high quality, but the investments are not in every case guaranteed or fully insured. As a result of recent changes in the credit market, one of Ligand’s short term investments in commercial paper is in default. Ligand intends to pursue collection efforts, but it might not recoup some or all of its investment in the commercial paper. In addition, from time to time Ligand may suffer other losses on its short term investment portfolio.

Ligand may require additional money to run its business and may be required to raise this money on terms which are not favorable to it or which reduce its stock price.

Ligand may need to complete additional equity or debt financings to fund its operations. Ligand’s inability to obtain additional financing could adversely affect its business. Financings may not be available at all or on terms favorable to Ligand. In addition, these financings, if completed, may not meet Ligand’s capital needs and could result in substantial dilution to its stockholders.

If adequate funds are not available, Ligand may be required to delay, reduce the scope of or eliminate one or more of its research or drug development programs. Ligand may also be required to liquidate its business or file for bankruptcy protection. Alternatively, Ligand may be forced to attempt to continue development by entering into arrangements with collaborative partners or others that require it to relinquish some or all of its rights to technologies or drug candidates that it would not otherwise relinquish.

Ligand’s drug development programs will require substantial additional future funding which could hurt its operational and financial condition.

Ligand’s drug development programs require substantial additional capital to successfully complete them, arising from costs to: conduct research, preclinical testing and human studies; establish pilot scale and commercial scale manufacturing processes and facilities; and establish and develop quality control, regulatory, marketing, sales and administrative capabilities to support these programs.

Ligand’s future operating and capital needs will depend on many factors, including: the pace of scientific progress in Ligand’s research and development programs and the magnitude of these programs; the scope and results of preclinical testing and human studies; the time and costs involved in obtaining regulatory approvals; the time and costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims; competing technological and market developments; Ligand’s ability to establish additional collaborations; changes in Ligand’s existing collaborations; the cost of manufacturing scale-up; and the effectiveness of Ligand’s commercialization activities.

Ligand expects its research and development expenditures over the next three years to continue to be significant. However, Ligand bases its outlook regarding the need for funds on many uncertain variables. Such uncertainties include regulatory approvals, the timing of events outside Ligand’s direct control such as product launches by partners and the success of such product launches, negotiations with potential strategic partners,

 

35


Table of Contents

possible sale of assets or other transactions and other factors. Any of these uncertain events can significantly change Ligand’s cash requirements.

While Ligand expects to fund its research and development activities primarily from cash generated from AVINZA and PROMACTA royalties and royalties and milestones from Ligand’s partners in various past and future collaborations to the extent possible, if Ligand is unable to do so, it may need to complete additional equity or debt financings or seek other external means of financing. These financings could depress Ligand’s stock price. If additional funds are required to support Ligand’s operations and it is unable to obtain them on terms favorable to Ligand, Ligand may be required to cease or reduce further development or commercialization of its products, to sell some or all of its technology or assets or to merge with another entity.

Significant returns of products Ligand sold before selling its commercial businesses could harm its operating results.

Under Ligand’s agreements to sell its commercial businesses, Ligand remains financially responsible for returns of its products sold before those businesses were transferred to their respective buyers. Consequently, if returns of those products are higher than expected, Ligand could incur substantial expenses for processing and issuing refunds for those returns which, in turn, could negatively impact Ligand’s financial results. The amount of returns could be affected by a number of factors including, but not limited to, ongoing product demand, product rotation at distributors and wholesalers, and product stability issues.

Ligand’s results of operations and liquidity needs could be materially negatively affected by market fluctuations and economic downturn.

Ligand’s results of operations could be materially negatively affected by economic conditions generally, both in the U.S. and elsewhere around the world. Continuing concerns over inflation, energy costs, geopolitical issues, the availability and cost of credit, the U.S. mortgage market and a declining residential real estate market in the U.S. have contributed to increased volatility and diminished expectations for the economy and the markets going forward. These factors, combined with volatile oil prices, declining business and consumer confidence and increased unemployment, have precipitated an economic recession and fears of a possible depression. Domestic and international equity markets continue to experience heightened volatility and turmoil. These events and the continuing market upheavals may have an adverse effect on Ligand. In the event of a continuing market downturn, Ligand’s results of operations could be adversely affected by those factors in many ways, including making it more difficult for Ligand to raise funds if necessary, and Ligand’s stock price may further decline.

Ligand’s investment securities consist primarily of money market funds, corporate debt obligations and U.S. government agency securities. Ligand does not have any auction rate securities. Recently, there has been concern in the credit markets regarding the value of a variety of mortgage-backed securities and the resultant effects on various securities markets. Ligand cannot provide assurance that its investments are not subject to adverse changes in market value. If Ligand’s investments experience adverse changes in market value, Ligand may have less capital to fund its operations.

Ligand may be unable to successfully integrate the business of Pharmacopeia and realize the anticipated benefits of the merger.

In December 2008, Ligand completed its merger with Pharmacopeia. The success of the merger will depend, in part, on Ligand’s ability to realize the anticipated synergies, growth opportunities and cost savings from integrating Pharmacopeia’s business with Ligand’s business. Ligand’s success in realizing these benefits and the timing of this realization depend upon the successful integration of the operations of Pharmacopeia. The integration of two independent companies is a complex, costly and time-consuming process. It is possible that the integration process could result in the loss of key employees, diversion of each company’s management’s attention, the disruption or interruption of, or the loss of momentum in, each company’s ongoing business or

 

36


Table of Contents

inconsistencies in standards, controls, procedures and policies, any of which could adversely affect either company’s ability to maintain relationships with licensors, collaborators, partners, suppliers and employees or Ligand’s ability to achieve the anticipated benefits of the merger, or could reduce Ligand’s earnings or otherwise adversely affect the business and financial results of the combined company and, as a result, adversely affect the market price of Ligand’s common stock.

Ligand expects to incur significant costs and commit significant management time integrating Pharmacopeia’s business operations, technology, development programs, products and personnel with those of Ligand. If Ligand does not successfully integrate the business of Pharmacopeia, the expenditure of these costs will reduce Ligand’s cash position.

Impairment charges pertaining to goodwill, identifiable intangible assets or other long-lived assets from the merger with Pharmacopeia could have an adverse impact on Ligand’s results of operations and the market value of Ligand’s common stock.

The total purchase price pertaining to Ligand’s merger with Pharmacopeia has been allocated to Pharmacopeia’s net tangible assets, identifiable intangible assets, in process research and development and goodwill. To the extent the value of goodwill or identifiable intangible assets or other long-lived assets become impaired, Ligand will be required to incur material charges relating to the impairment. Any impairment charges could have a material adverse impact on Ligand’s results of operations and the market value of its common stock. A similar risk would pertain to any other acquisition Ligand makes.

Ligand may undertake strategic acquisitions in the future (including an acquisition of Neurogen Corporation) and any difficulties from integrating such acquisitions could adversely affect Ligand’s stock price, operating results and results of operations.

Ligand may acquire companies, businesses and products that complement or augment Ligand’s existing business. Ligand may not be able to integrate any acquired business successfully or operate any acquired business profitably. Integrating any newly acquired business could be expensive and time-consuming. Integration efforts often take a significant amount of time, place a significant strain on managerial, operational and financial resources and could prove to be more difficult or expensive than Ligand predicts. The diversion of Ligand’s management’s attention and any delay or difficulties encountered in connection with any future acquisitions Ligand may consummate could result in the disruption of Ligand’s on-going business or inconsistencies in standards and controls that could negatively affect Ligand’s ability to maintain third-party relationships. Moreover, Ligand may need to raise additional funds through public or private debt or equity financing, or issue additional shares, to acquire any businesses or products, which may result in dilution for stockholders or the incurrence of indebtedness.

As part of Ligand’s efforts to acquire companies, business or product candidates or to enter into other significant transactions, Ligand conducts business, legal and financial due diligence with the goal of identifying and evaluating material risks involved in the transaction. Despite Ligand’s efforts, it ultimately may be unsuccessful in ascertaining or evaluating all such risks and, as a result, might not realize the intended advantages of the transaction. If Ligand fails to realize the expected benefits from acquisitions it may consummate in the future, whether as a result of unidentified risks, integration difficulties, regulatory setbacks and other events, Ligand’s business, results of operations and financial condition could be adversely affected. If Ligand acquires product candidates, it will also need to make certain assumptions about, among other things, development costs, the likelihood of receiving regulatory approval and the market for such product candidates. Ligand’s assumptions may prove to be incorrect, which could cause it to fail to realize the anticipated benefits of these transactions.

In addition, Ligand will likely experience significant charges to earnings in connection with its efforts, if any, to consummate acquisitions. These charges may include fees and expenses for investment bankers, attorneys, accountants and other advisors in connection with Ligand’s efforts. In addition, if Ligand’s efforts are

 

37


Table of Contents

successful, it may incur, as part of a transaction, substantial charges for closure costs associated with elimination of duplicate operations and facilities and acquired in-process research and development charges. In either case, the incurrence of these charges could adversely affect Ligand’s results of operations for particular quarterly or annual periods.

The above risks may all apply with regard to Ligand’s planned acquisition of Neurogen Corporation, which is scheduled to be completed (subject to the satisfaction or waiver of closing conditions) in December 2009.

The drug research and development industry is highly competitive and subject to technological change, and Ligand may not have the resources necessary to compete successfully.

Many of Ligand’s competitors have access to greater financial, technical, research, marketing, sales, reputation, distribution, service and other resources than Ligand does. Moreover, the pharmaceutical and biotechnology industries are characterized by continuous technological innovation. Ligand anticipates that it will face increased competition in the future as new companies enter the market and its competitors make advanced technologies available. Technological advances or entirely different approaches that Ligand or one or more of its competitors develop may render Ligand’s products, services and expertise obsolete or uneconomical. Additionally, the existing approaches of Ligand’s competitors or new approaches or technologies that its competitors develop may be more effective than those Ligand develops. Ligand may not be able to compete successfully with existing or future competitors.

Ligand has excess space available for sublease at its facilities and it may not be able to find qualified sublease tenants.

Ligand has, as a result of its acquisition of Pharmacopeia, long-term, non-cancellable real estate arrangements for space which is considered to be in excess of Ligand’s current requirements. Ligand currently is actively looking for additional sublease tenants to sublease up to approximately 80,000 square feet of vacant space or space that could be made available through changes in the current layout of Ligand’s operations. Ligand will continue to be responsible for all carrying costs of these facilities until such time as it can sublease these facilities or terminate the applicable leases based on the contractual terms of the lease agreements. However, the commercial real estate market conditions in the United States have resulted in a surplus of business facilities making it difficult to sublease properties. If Ligand is unable to find additional sublease tenants it may not meet its expected estimated levels of sublease income or it may be required to terminate these leases at a substantial cost, and, accordingly, its results of operations could be materially and adversely affected.

Metabasis is furnishing this proxy statement/prospectus to Metabasis stockholders in connection with the solicitation of proxies by the Metabasis board of directors for use at the special meeting of stockholders, including any adjournment or postponement of the special meeting.

Date, Time and Place

Metabasis will hold its special meeting on [                    ], 2010 at [            ] a.m., local time, at the offices of Cooley Godward Kronish LLP, located at 4401 Eastgate Mall, San Diego, California 92121.

Purpose of the Meeting

At the special meeting, the Metabasis stockholders will be asked to consider and vote upon the following matters:

 

   

A proposal to adopt the Agreement and Plan of Merger, dated as of October 26, 2009 (and as amended), by and among Ligand Pharmaceuticals Incorporated, Moonstone Acquisition, Inc., a wholly owned subsidiary of Ligand, Metabasis’ stockholders’ representative and Metabasis, and approve the merger contemplated by the merger agreement. A copy of the merger agreement is attached as Annex A to this proxy statement/prospectus accompanying this notice;

 

   

A proposal to adjourn the special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the special meeting to adopt the merger agreement and approve the merger; and

 

   

To transact such other business as may properly come before the special meeting and any adjournments or postponements thereof.

Quorum Required

Metabasis’ bylaws provide that the holders of a majority of the shares of Metabasis common stock issued and outstanding and entitled to vote at the special meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business at the special meeting. Abstentions and broker non-votes will be counted as present for the purpose of determining the presence of a quorum. In the event that a quorum is not present at the special meeting, the special meeting may be adjourned or postponed to solicit additional proxies.

Voting Rights

Metabasis common stock is the only type of security entitled to vote at the special meeting. On [                    ], 2009, the record date for determination of stockholders entitled to vote at the special meeting, there were [            ] shares of Metabasis common stock outstanding. Each Metabasis stockholder of record on [                    ], 2009 is entitled to one vote for each share of Metabasis common stock held by such stockholder on that date. All votes will be tabulated by the inspector of election appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes.

Proxies

Whether or not you are able to attend Metabasis’ special meeting of stockholders, you are urged to complete and return the enclosed proxy, which is solicited by Metabasis’ board of directors and which will be voted as you direct on your proxy card when properly completed. In the event no directions are specified, executed proxies will be voted FOR the adoption of the merger agreement and approval of the merger, FOR the proposal to

adjourn the special meeting to permit further solicitation of proxies if there are not sufficient votes to adopt the merger agreement and approve the merger, and, in the discretion of the proxy holders, as to any other matters that may properly come before the special meeting. All shares represented by a valid proxy received before the special meeting will be voted.

Revocation of Proxies

You may also revoke or change your proxy at any time before the special meeting. To do this, send a written notice of revocation or another signed proxy with a later date to the Secretary at Metabasis’ principal executive offices in time to be received before the beginning of the special meeting. You may also revoke your proxy by attending the special meeting and voting in person.

Metabasis Votes Required

The affirmative vote of the holders of record of a majority of the outstanding shares of Metabasis common stock is required to adopt the merger agreement and approve the merger, and the affirmative vote of the holders of record of a majority of the shares of Metabasis common stock present and entitled to vote at the special meeting is required to adopt the proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies. If a broker or other nominee holding shares of Metabasis common stock or a holder of Metabasis common stock fails to vote on the adoption of the merger agreement and the approval of the merger or responds to that proposal with an “abstain” vote, it will have the same effect as a vote against that proposal. If a broker or other nominee holding shares of Metabasis common stock or a holder of Metabasis common stock responds to the proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies with an “abstain” vote, it will have the same effect as a vote against that proposal. If a broker or other nominee holding Metabasis common stock or a holder of Metabasis common stock fails to vote on the proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies, it will have no effect on the outcome of the vote for that proposal.

As of [                    ], 2009, (i) the directors and executive officers of Metabasis beneficially owned [            ] shares of Metabasis common stock entitled to vote, representing approximately [    ]% of the outstanding shares of Metabasis common stock entitled to vote at the special meeting and (ii) Ligand and its affiliates beneficially owned [            ] shares of Metabasis common stock entitled to vote, representing approximately 28.9% of the outstanding shares of Metabasis common stock entitled to vote at the special meeting. However, due to the voting agreements described below, approximately [    ]% of the outstanding shares of Metabasis common stock are included in both groups; and so, the aggregate total beneficially owned is approximately [    ]%.

MPM Asset Management Investors 2000 B LLC, MPM BioVentures II, L.P., MPM BioVentures II-QP, L.P., MPM BioVentures GMBH&Co Parallel- Beteiligungs KG, InterWest Partners VII, L.P., InterWest Investors VII, L.P. and all the directors and officers of Metabasis as of October 26, 2009, who as of that date collectively owned approximately 28.9% of the outstanding shares of Metabasis common stock, have entered into voting agreements with Ligand pursuant to which such stockholders have agreed, among other things, to vote the shares of common stock of Metabasis owned by them in favor of adopting the merger agreement and approving the merger. For a description of the voting agreements, see “Certain Terms of the Merger Agreement—Voting Agreements” beginning on page  101 of this proxy statement/prospectus.

Recommendation of Metabasis’ Board of Directors

The board of directors of Metabasis has determined and believes that the merger agreement and the merger are advisable for, and in the best interests of, Metabasis and its stockholders and has approved such items. The board of directors of Metabasis unanimously recommends that Metabasis stockholders vote FOR adoption of the merger agreement and approval of the merger.

The board of directors of Metabasis unanimously recommends that Metabasis stockholders vote FOR approval of the possible adjournment or postponement of the special meeting of Metabasis stockholders.

Voting in Person

If you plan to attend Metabasis’ special meeting and wish to vote in person, you will be given a ballot at the special meeting.

You should submit your completed proxy even if you plan to attend the special meeting. If you are the stockholder of record of your shares of Metabasis common stock, you can change your vote at the special meeting. If you hold shares in street name, you may not vote in person at the special meeting unless you obtain a signed proxy from the record holder giving you the right to vote the shares in person at the meeting.

Your vote is important. Accordingly, please sign and return the enclosed proxy card whether or not you plan to attend the special meeting in person.

Adjournments and Postponements

Although it is not currently expected, the special meeting may be adjourned or postponed to a later date or time, if necessary or appropriate, to solicit additional proxies in the event there are insufficient votes at the time of the special meeting to adopt the merger agreement. Metabasis’ bylaws provide that notice need not be given of the adjourned meeting if the time and place of the adjourned meeting are announced at the meeting at which the adjournment is taken. At the adjourned meeting, Metabasis may transact any business that might have been transacted at the original meeting. If the adjournment is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Any signed proxies received by Metabasis in which no voting instructions are provided on such matter will be voted FOR an adjournment of the special meeting to a later date or time, if necessary or appropriate, to solicit additional proxies in the event there are insufficient votes at the time of the special meeting to adopt the merger agreement, and the transactions contemplated by the merger agreement, including the merger. Whether or not a quorum exists, holders of a majority of the shares of Metabasis’ common stock present in person or represented by proxy at the special meeting may adjourn the special meeting. Because a majority of the votes represented at the meeting, whether or not a quorum exists, is required to approve the proposal to adjourn the meeting, abstentions will have the same effect on such proposal as a vote AGAINST the proposal. Broker non-votes and any shares that are not voted will have no effect on the proposal to adjourn the special meeting. Metabasis stockholders who have already sent in their proxies may revoke them at any time before their use at the special meeting as adjourned or postponed.

Stock Certificates

You should not send in any stock certificates with your proxy card. If you are a Metabasis stockholder, after the merger is completed, a letter of transmittal will be sent to you informing you where to deliver your Metabasis stock certificates in order to receive the merger consideration. You should not send in your Metabasis common stock certificates before receiving this letter of transmittal.

Solicitation of Proxies

Metabasis will bear the cost of this solicitation, including the printing and mailing of this proxy statement/prospectus, the proxy and any additional soliciting material furnished to the Metabasis stockholders. Copies of solicitation material will be furnished to brokerage houses, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward this solicitation material to such beneficial

THE MERGER

General

The discussion of the merger in this proxy statement/prospectus and the description of the merger are only summaries of the material features of the proposed merger. Metabasis stockholders can obtain a more complete understanding of the merger by reading the merger agreement and the forms of CVR agreements, copies of which are attached to this proxy statement/prospectus as Annex A, Annex B, Annex C, Annex D and Annex E. Metabasis stockholders are encouraged to read the merger agreement and the other annexes to this proxy statement/prospectus in their entirety.

General Description of the Merger

In the merger, Merger Sub will merge with and into Metabasis, with Metabasis continuing as the surviving entity.

Upon completion of the merger, each share of Metabasis common stock will be converted into the right to receive a pro rata portion of a total cash payment equal to $3,207,500 (cash consideration) less Metabasis’ estimated net liabilities (as defined in the merger agreement) at closing and also less $150,000 to be deposited in the Stockholders’ Representative’s fund. Metabasis currently estimates the total closing payment to be approximately $1.8 million in cash.

At the closing of the merger, Ligand, Metabasis and a rights agent will also enter into up to four contingent value rights agreements, or CVR agreements, the forms of which are attached to this proxy statement/prospectus as Annex B, Annex C, Annex D and Annex E. The CVR agreements set forth the rights that former Metabasis stockholders will have with respect to each CVR to be held by them after the closing of the merger. Each Metabasis stockholder will receive one CVR (in book-entry form) under each of the four CVR agreements for each share of Metabasis stock held. The CVRs will not be listed on any securities exchange but will be generally tradable, subject to certain procedures as set forth in more detail in this proxy statement/prospectus.

Treatment of Stock Options and Warrants

Metabasis’ board of directors will take, except to the extent that by virtue of existing agreements no action is required, all requisite actions such that each holder of outstanding Metabasis options shall be entitled to exercise in full all Metabasis options held by such holder immediately before the effective time of the merger, and such that all outstanding Metabasis options not exercised before the effective time of the merger shall be terminated and canceled without any payment by Metabasis. No replacement options will be issued.

Metabasis has agreed to use reasonable best efforts to enter into agreements with the holders of outstanding Metabasis warrants to terminate and cancel all such warrants, effective immediately before the effective time of the merger, without any payment or liability on the part of Metabasis. If any Metabasis warrant remains outstanding after the effective time of the merger and the holder thereof exercises such Metabasis warrant before its expiration or termination date, then Ligand shall issue and pay in respect of each such exercised Metabasis warrant, on a per-exercised-share basis, equivalent consideration as is paid in respect of each issued and outstanding share of Metabasis common stock as of immediately before the merger.

See the section entitled “Certain Terms of the Merger Agreement—Metabasis Stock Options and Warrants” beginning on page  78 of this proxy statement/prospectus.

Background of the Merger

Beginning in mid-2007, Metabasis suffered a series of clinical and operational setbacks that led to a significant decline in its market capitalization. In July 2007, Metabasis announced that it had been informed by its strategic collaborator, Daiichi Sankyo, that results from a three-month Phase 2b clinical trial of Metabasis’ product candidate CS-917 for type 2 diabetes failed to meet the efficacy endpoint established for the trial. At the same time, Metabasis announced that it had been advised by Schering-Plough Corporation of its intention to terminate agreements it entered into with Metabasis and Valeant Pharmaceuticals International in December 2006 for the development and commercialization of Metabasis’ product candidate pradefovir, due in part to 24-month carcinogenicity studies in mice and rats that found an increased incidence of tumors at higher doses. In October 2007, the research term of Metabasis’ collaboration agreement with Idenix Pharmaceuticals Inc. to apply Metabasis’ HepDirect technology to certain Idenix lead compounds with the goal of improving the safety and efficacy of those compounds for treating hepatitis C ended upon the first anniversary of the agreement, and the agreement subsequently terminated in accordance with its terms, with no product candidate designated.

As a result of these events, Metabasis’ management and board of directors reviewed its strategic plan to determine how best to proceed with key programs which they believed would drive significant value for Metabasis, while also taking steps to slow growth and reduce expenses. In light of its limited financial resources,

Table of Contents

Metabasis planned to focus its internal resources and efforts on its core metabolic disease programs, MB07803 and MB07811, and to establish one or more strategic collaborations to accelerate progress and share risk while conserving capital. A critical component in Metabasis’ revised strategy was the partnering of its advanced research program intended to create a glucagon receptor antagonist drug for the treatment of type 2 diabetes. During 2008, Metabasis contacted over 20 different pharmaceutical companies and presented confidential material for this program to approximately nine pharmaceutical companies identified as potential collaborators, of which five engaged in due diligence efforts regarding the Glucagon Program. Two pharmaceutical companies, referred to as “Company A” and “Company B,” expressed significant interest in the Glucagon Program following their initial due diligence, and negotiated term sheets with Metabasis during the third quarter of 2008 relating to a potential collaboration for the program. However, following additional due diligence, during the fourth quarter of 2008 both Company A and Company B elected not to proceed further with the collaboration discussions given the early stage of the Glucagon Program and the perceived amount of time necessary to advance any resulting compounds into clinical development.

Although Metabasis was able to enter into a two-year research collaboration agreement with Hoffmann-La Roche Inc., Roche Palo Alto LLC and F. Hoffmann-La Roche Ltd., or Roche, in August 2008, the goal of which was to apply Metabasis’ HepDirect technology to Roche’s proprietary lead nucleosides in order to develop new treatments for hepatitis C, its inability to complete a collaboration on the Glucagon Program or to derive sufficient funding from its other business development efforts during 2008 led Metabasis’ management and board of directors to conclude that a major strategic realignment was necessary. Accordingly, in November 2008, Metabasis announced a restructuring of its operations that resulted in a reduction of 35 employees, or approximately 30% of its then total workforce, and the closing of a satellite facility in Ann Arbor, Michigan. In January 2009, Metabasis announced a second restructuring of its operations that resulted in a reduction of an additional 38 employees, or approximately 43% of its then total workforce. Also, in December 2008, Metabasis announced that Paul Laikind, Ph.D., had resigned as its President and Chief Executive Officer to pursue other opportunities, and that Mark D. Erion, Ph.D., Metabasis’ Chief Scientific Officer and Executive Vice President of Research and Development, had been named President, Chief Executive Officer and Chief Scientific Officer.

Following this strategic realignment, in January 2009, Metabasis further revised its operating plan to narrow its research and development focus and increase its efforts to monetize certain of its assets and/or form strategic collaborations to fund its continuing operations. Metabasis planned to utilize a significant portion of its existing resources on a planned Phase 2 clinical trial for MB07811 and to continue to support its collaboration with Roche as well as its ongoing collaboration with Merck & Co., Inc., or Merck, to research, develop and commercialize novel small molecule therapeutics with the potential to treat type 2 diabetes, and potentially other metabolic diseases, by activating an enzyme in the liver called AMP-activated Protein Kinase. Metabasis also committed resources toward the advancement of certain advanced research programs, including the Glucagon Program, which it believed would improve its ability to secure additional financial resources under a collaboration.

At the same time, Metabasis initiated efforts to consider a potential equity financing, and a special committee of the Metabasis board of directors, consisting of Daniel D. Burgess, M.B.A., David F. Hale and William R. Rohn, was appointed to evaluate and review various financing transactions on behalf of the Metabasis board and approve whether to proceed with a transaction and if so, on what terms and conditions. Also, in March 2009, Metabasis announced the hiring of Tran B. Nguyen, M.B.A., an individual with extensive investment banking experience, as Vice President and Chief Financial Officer, and engaged a nationally-recognized investment banking firm to act as exclusive placement agent to Metabasis in connection with a potential financing transaction.

On February 25, 2009, Dr. Erion met with John Higgins, Ligand’s President and Chief Executive Officer, and engaged in a high-level discussion of Metabasis and Ligand and whether there might be a potential strategic fit between the two companies. In the week following the meeting, Metabasis and Ligand executed a mutual non-disclosure agreement. On March 9, 2009, a follow-up meeting attended by Dr. Erion, Mr. Nguyen, David Hale (Metabasis’ Chairman) and Mr. Higgins was held at Metabasis’ offices to further discuss the possibility of a

Table of Contents

transaction involving Metabasis and Ligand. On April 1, 2009, Mr. Nguyen and Mr. Higgins had a brief telephone call to discuss Metabasis’ financial statements. However, in late April 2009, Metabasis communicated to Ligand that it wished to suspend these discussions regarding a potential transaction in order to allow Metabasis’ management team to focus on its near term business development efforts and on the financing process then underway.

From March through May 2009, Metabasis’ exclusive placement agent contacted approximately 80 institutional investors that it believed might be interested in investing in an equity financing of Metabasis. Approximately 20 of the investors contacted by the placement agent held in-person or telephonic follow-up meetings with Metabasis management and representatives of the placement agent. During the same time frame, the special committee of Metabasis’ board of directors, together with management and Metabasis’ outside legal counsel, Cooley Godward Kronish LLP, or Cooley, also considered the terms of an alternate private placement transaction proposed by certain major existing investors of Metabasis, and engaged in discussions with such investors regarding the alternate transaction. One institutional investor contacted by the placement agent engaged in extensive due diligence with respect to Metabasis and provided initial positive feedback regarding its interest in leading an equity financing of Metabasis. However, in late May 2009, that institutional investor notified Metabasis that it did not wish to proceed with the financing. It was also determined that there was insufficient interest from the other investors contacted by the exclusive placement agent in participating in an equity financing of Metabasis, and that the major existing investors in Metabasis were no longer willing to provide additional equity funding.

Due to its difficulty in raising sufficient capital from a financing or other sources, and in order to provide the Metabasis board of directors additional time to evaluate strategic alternatives, on May 27, 2009, Metabasis discontinued all research and development activities and announced a third corporate restructuring that resulted in a reduction of an additional 45 employees, or approximately 85% of its then total workforce. At the same time, Metabasis was notified by Oxford Finance Corporation, or Oxford, that the material adverse change and insolvency events of default under the terms of Oxford’s loan and security agreement with Metabasis had occurred, which required full payment by Metabasis of all amounts due to Oxford. Metabasis paid Oxford $6.8 million against the outstanding principal and interest due, and agreed to new terms for the remittance of the remaining loan balance of $200,000. Also in late May, Metabasis received a letter from the NASDAQ Stock Market informing Metabasis of its non-compliance with the requirement that it maintain a minimum of $2.5 million in stockholders’ equity in order to maintain its listing on the NASDAQ Capital Market.

Due to these events, Metabasis commenced a series of focused efforts intended to address its near term cash needs and maximize its potential strategic alternatives. On June 5, 2009, Metabasis announced that it had entered into a letter agreement with Roche, which provided for the early payment by Roche of a $2.0 million milestone payment in exchange for certain know-how. On June 10, 2009, Metabasis announced that it had amended its AMP-activated Protein Kinase collaboration agreement with Merck to provide for a one-time, nonrefundable payment by Merck of $6.0 million to Metabasis to satisfy all potential future milestone and royalty payments payable by Merck under the collaboration agreement. In July 2009, Metabasis terminated its lease for its corporate headquarters facility, and obtained a continued occupancy right through January 2, 2010; the consideration Metabasis gave in the transaction included a contingent payment right of up to $1.5 million. Also in July 2009, Metabasis entered into an agreement to sell its laboratory and office equipment.

Having addressed these near-term issues, Metabasis sought to obtain additional resources through the licensing or selling of its product pipeline and potentially through other strategic alternatives, recognizing that in the event it was unsuccessful in the near term in its efforts to secure additional resources, it would be required to cease operations entirely due to the inadequacy of Metabasis’ cash resources. From June through August 2009, Metabasis continued to engage in significant partnering efforts focused primarily on the Glucagon Program, including extensive discussions with Company B and another pharmaceutical company, referred to herein as “Company C.”

On June 13, 2009, Dr. Erion contacted Mr. Higgins to determine whether he had an interest in continuing the parties’ previous conversations regarding a potential transaction involving Ligand and Metabasis, but this did not lead to substantial further discussions at the time. On August 17, 2009, Dr. Erion re-contacted Mr. Higgins, at which time Ligand expressed an interest in further reviewing the opportunity.

On August 24, 2009, Ligand announced it had entered into a definitive merger agreement under which Ligand would acquire Neurogen Corporation.

On August 25, 2009, a meeting was held at Metabasis involving members of both companies’ management teams during which Ligand engaged in a due diligence review of several of Metabasis’ drug development programs.

On August 26, 2009, Dr. Erion notified Metabasis of his intent to, effective October 31, 2009, resign as President, Chief Executive Officer and Chief Scientific Officer and as a member of the Metabasis board of directors, to join Merck as its vice president and worldwide basic franchise head of Diabetes and Obesity. In connection with Dr. Erion’s prospective resignation, on August 27, 2009, Metabasis’ board of directors appointed David F. Hale as Executive Chairman effective September 1, 2009. Metabasis announced Dr. Erion’s prospective resignation and Mr. Hale’s appointment on September 1, 2009.

On August 27, 2009, Metabasis retained Merriman Curhan Ford & Co., or Merriman, to explore and evaluate strategic alternatives, and subsequently announced its engagement of Merriman via a press release issued on September 3, 2009. Pursuant to its engagement, in early September 2009, Merriman began contacting companies that it believed might be interested in a potential acquisition of Metabasis.

On September 1, 2009, Mr. Higgins and Dr. Erion had a telephone conversation regarding the general structure and terms of a potential transaction involving Ligand and Metabasis.

On September 2, 2009, Mr. Higgins sent Dr. Erion an initial letter of intent outlining the terms for a potential acquisition of Metabasis by Ligand. Over the next several days, Dr. Erion and Mr. Higgins discussed the terms of the letter of intent by e-mail and by phone. On September 11, 2009, the Metabasis board of directors held a meeting at which Dr. Erion and Mr. Nguyen discussed the Ligand letter of intent and reported on the status of Merriman’s evaluation of strategic alternatives and on partnering discussions for the Glucagon Program. Following the Metabasis board meeting, Dr. Erion provided additional feedback to Mr. Higgins, and on September 17, 2009, Mr. Higgins sent Dr. Erion a revised letter of intent outlining the terms for a potential acquisition of Metabasis by Ligand.

On September 15, 2009, Metabasis announced that it expected to regain compliance with the minimum $2.5 million stockholders’ equity requirement for continued listing on the NASDAQ Capital Market as of September 18, 2009. However, Metabasis also announced that it had received a letter from the NASDAQ Stock Market informing Metabasis of its non-compliance with a separate continued listing requirement relating to the maintenance of a minimum closing bid price of $1.00 per share or more, and indicating that Metabasis had until March 15, 2010, to regain compliance.

On September 21, 2009, the Metabasis board of directors held a meeting at which the Metabasis board reviewed and discussed the revised letter of intent received from Mr. Higgins on September 17, 2009; Mr. Nguyen updated the Metabasis board regarding Merriman’s evaluation of strategic alternatives; and Dr. Erion reported on the status of discussions with Company C regarding the partnering of the Glucagon Program and advised the Metabasis board that Company B had decided to pass on the opportunity. A representative of Cooley who was present at the meeting advised the Metabasis board on its fiduciary duties with respect to the consideration of such transactions.

On September 22, 2009, the Ligand board of directors reviewed in detail the possible merger with Metabasis, including background information on Metabasis, deal structure, technology owned or controlled by Metabasis, and major programs and agreements of Metabasis.

On September 22, 2009, Dr. Erion e-mailed Mr. Higgins a counterproposal regarding certain terms of the revised letter of intent received from Mr. Higgins on September 17, 2009. Over the next two days, Dr. Erion and Mr. Higgins discussed the counterproposal by e-mail and by phone. On September 25, 2009, the Metabasis board of directors held a meeting at which Mr. Nguyen and representatives of Merriman and Cooley were present. Dr. Erion and Mr. Nguyen summarized the then-current terms of the proposed transaction with Ligand; the Merriman representatives reviewed their ongoing process of evaluating strategic alternatives for the company and shared their perspective on the terms of the proposed transaction with Ligand; and the Metabasis board determined to proceed with negotiations with Ligand while simultaneously moving forward with the Merriman process. On September 29, 2009, Mr. Higgins sent to Dr. Erion a term sheet which took into account the substantive discussions of the parties through that date, and the parties transitioned from a letter of intent/term sheet preparation process to a definitive transaction agreements preparation process.

Beginning on September 25, 2009, Ligand commenced significant further due diligence efforts with respect to Metabasis. On September 30, 2009, a meeting was held at Metabasis involving members of both companies’ management teams during which Ligand engaged in a detailed due diligence review of Metabasis’ drug development programs and business development efforts. John Kozarich, Ligand’s Chairman, participated in this meeting. On October 2, 2009, a follow-up due diligence meeting was held involving various Ligand scientists and the Metabasis management team, in which additional details were presented on Metabasis’ programs. In addition, representatives of Ligand and its outside counsel, Stradling Yocca Carlson & Rauth, or Stradling, reviewed various due diligence materials either at Metabasis or via an on-line data room throughout October.

On October 1, 2009, Charles Berkman, Ligand’s Vice President, General Counsel and Secretary, sent Dr. Erion a draft confidentiality and exclusivity agreement. Dr. Erion responded later that day with comments to the agreement, the most significant of which was to delete the proposed 30-day exclusivity clause of the agreement, as Merriman remained engaged in its process of evaluating strategic alternatives for Metabasis, and Metabasis continued to pursue discussions regarding the Glucagon Program with Company C.

On the evening of October 2, 2009, initial drafts of the definitive agreements for the transaction were distributed by Stradling to Cooley. On the morning of October 5, 2009, Cooley and Stradling held a call in which Cooley orally provided initial comments on the draft definitive transaction agreements. On the evening of October 6, 2009 Cooley sent written comments on the draft definitive transaction agreements to Stradling. At various times during the week of October 5, 2009, representatives of Cooley, Stradling, Ligand and Metabasis engaged in negotiations regarding the terms of the draft confidentiality and exclusivity agreement. Also, on October 5, 2009, Stradling shared with Cooley a draft voting agreement that Ligand expected to be signed by all of the directors and executive officers and by certain major stockholders of Metabasis.

On October 9, 2009, the Metabasis board of directors held a meeting at which Mr. Nguyen and representatives of Merriman and Cooley were present. Dr. Erion reviewed the status of discussions with Company C regarding the partnering of the Glucagon Program. The Merriman representatives reported on the outcome of their process of exploring and evaluating strategic alternatives for Metabasis. They indicated that they had contacted 47 companies that Merriman believed might be interested in a potential acquisition of Metabasis; that 22 of the targets had passed on the opportunity, 10 of them had not responded at all, and 13 of them had not responded after receiving initial non-confidential information; and that the remaining two targets (one of which had provided a highly conditional and non-specific indication of interest and was not viewed by Merriman or the Metabasis board of directors as a viable acquirer, and the other of which had not provided an indication of interest) had expressed an inability to meet the timeline established by Metabasis for a response. It was also noted that the Merriman process had been commenced following Metabasis’ public announcement of its engagement of Merriman, and that any interested companies not on Merriman’s target list had had an opportunity

to contact Merriman and/or Metabasis. Dr. Erion, Mr. Nguyen and the Cooley representatives discussed the status of Ligand’s due diligence efforts and the status of the definitive transaction agreement negotiations and the remaining major open issues. The Cooley representatives also discussed the implications of the foregoing matters with respect to the fiduciary duties of the Metabasis board. The Metabasis board then authorized continued negotiations with Ligand and the execution of a confidentiality and exclusivity agreement with an exclusivity clause extending to October 31, 2009, subject to Metabasis’ management obtaining concessions from Ligand on certain terms being negotiated in the draft definitive transaction agreements.

On October 9, 2009, Company C advised Metabasis that it had decided not to proceed with further discussions regarding the partnering of the Glucagon Program.

On October 10 and 11, 2009, Dr. Erion provided Mr. Higgins with feedback from the Metabasis board meeting held on October 9, 2009, and they discussed via e-mail and phone the concessions requested by the Metabasis board as a condition to granting the requested temporary exclusivity. Mr. Higgins also met in person with Mr. Hale on October 12, 2009, to discuss such matters. Shortly following this meeting, Metabasis executed a confidentiality and exclusivity agreement with Ligand containing an exclusivity clause extending to October 31, 2009.

From October 12 to 24, 2009, representatives of Cooley, Stradling, Metabasis and Ligand engaged in negotiations regarding the final terms of the definitive transaction agreements, including successive exchanges of draft agreements. The Metabasis board of directors held two meetings during this time, on October 14 and 22, 2009, at which Mr. Nguyen and representatives of Cooley and Merriman participated and updated the Metabasis board on the status of the draft definitive transaction agreement negotiations and the remaining major open issues, and the Cooley representatives advised the Metabasis board with respect to their fiduciary duties with respect to the consideration of the Ligand transaction. On October 14, 2009, the Ligand board of directors met, at which meeting a representative of Stradling participated and (together with Mr. Higgins and management) updated the Ligand board on the status of the draft definitive transaction agreement negotiations and the settled and remaining open major issues, the rationale for doing the deal and the deal economics, Metabasis’ primary partnered and internal programs, and key risks and transaction considerations for the board. The Ligand board of directors approved the merger agreement and the merger via a unanimous written consent action dated as of October 22, 2009.

Drafts of the definitive transaction agreements were finalized by Cooley and Stradling on October 24, 2009.

On October 26, 2009, the Metabasis board of directors held a meeting at which Mr. Nguyen and representatives of Cooley and Merriman participated. The Cooley representatives referred the Metabasis board to the draft definitive transaction agreements that had been distributed in advance of the meeting, and reviewed a summary of such agreements that had been sent to the Metabasis board together with such materials. The Merriman representatives made a presentation to the Metabasis board, provided Merriman’s analysis as to the fairness of the merger consideration to be received by the holders of Metabasis common stock pursuant to the merger agreement, and expressed Merriman’s oral opinion (subsequently confirmed by its written opinion dated October 26, 2009) that, as of October 26, 2009, and based upon and subject to the factors and assumptions set forth in Merriman’s written opinion, the merger consideration to be received by the holders of Metabasis common stock pursuant to the merger agreement is fair from a financial point of view to such holders. The Metabasis board then unanimously adopted a set of resolutions relating to the transaction with Ligand including resolutions declaring that the merger agreement and the merger, upon the terms and subject to the conditions set forth in the merger agreement, are advisable and in the best interests of Metabasis and its stockholders, approving the merger agreement and the merger, and recommending that Metabasis stockholders adopt the merger agreement and approve the merger at a special meeting of Metabasis stockholders.

On the evening of October 26, 2009, the definitive merger agreement was executed by Metabasis, Ligand, Moonstone Acquisition, Inc. and David F. Hale, as Stockholders’ Representative, and voting agreements were executed by all of the directors and executive officers and by certain major stockholders of Metabasis.

On November 25, 2009, the Metabasis board of directors held a meeting at which Mr. Nguyen and representatives of Cooley participated. The Cooley representatives referred the Metabasis board to the draft amendment to the merger agreement that had been distributed in advance of the meeting. The Metabasis board then approved the amendment to the merger agreement and recommended that Metabasis stockholders adopt the merger agreement, as amended.

Metabasis’ Reasons for the Merger; Recommendation of Metabasis Board of Directors

At a meeting of the Metabasis board of directors on October 26, 2009, the members of the Metabasis board of directors unanimously declared that the merger agreement and the merger, upon the terms and subject to the conditions set forth in the merger agreement, are advisable and in the best interests of Metabasis and its stockholders. The Metabasis board of directors has approved the merger agreement and the merger, and recommends that Metabasis stockholders adopt the merger agreement and approve the merger at the special meeting of Metabasis stockholders.

In reaching its determinations to approve the merger agreement and recommend that Metabasis stockholders adopt the merger agreement and approve the merger, the Metabasis board of directors considered numerous factors discussed with Metabasis’ outside legal and financial advisors and senior management, including the following factors and benefits of the merger, each of which the Metabasis board of directors believed supported its determinations:

 

   

Metabasis’ Business, Financial Condition, Strategy and Prospects. The Metabasis board of directors’ familiarity with the business, operations, properties and assets, financial condition, business strategy and prospects of Metabasis, as well as the risks involved in achieving those prospects (including the risk factors set forth in Metabasis’ Annual Report on Form 10-K for the year ended December 31, 2008 and the risk factors subsequently set forth in Metabasis’ Quarterly Report on Form 10-Q for the quarter ended September 30, 2009), as well as the nature of the industry in which Metabasis competes, industry trends and economic and market conditions, both on a historical and a prospective basis;

 

   

Difficulty in Obtaining Additional Resources. The substantial risk that Metabasis would be unable to obtain additional resources necessary to continue operating on a stand-alone basis on acceptable terms, if at all (taking into account, among other things, the significant number of investors contacted during the equity financing process led by Metabasis’ exclusive placement agent from March through May 2009 and the lack of sufficient interest from those investors and the major existing investors in providing additional funding to Metabasis, as well as the recent challenges experienced by Metabasis in completing a business development transaction with respect to its Glucagon Program or other drug development assets), and the possibility that Metabasis would be required to cease operations entirely if additional resources could not be secured in the near term;

 

   

Solicitation of Other Parties. The results of the evaluation of strategic alternatives conducted by Merriman in September and October 2009, and specifically, the fact that notwithstanding Metabasis’ public announcement of its engagement of Merriman and Merriman’s significant efforts during the evaluation process, only 1 of the 47 companies contacted by Merriman provided any kind of formal indication of interest (and that the indication of interest provided was highly conditional and non-specific, and submitted by a company that was not viewed as a viable acquirer and which ultimately indicated that it was unable to meet the necessary timeline given the advanced stage of discussions with Ligand);

 

   

Identity of Acquirer. The publicly available information and information provided by Ligand concerning its businesses, financial condition, operating results and prospects, and the Metabasis board of directors’ belief that Ligand’s research and business development capabilities, which the Metabasis board of directors judged to be strong, coupled with Ligand’s financial position, which the Metabasis board of directors judged to be solid, and its commitment to additional research and development funding as part of the merger, gives Metabasis’ portfolio of programs the potential to deliver significant future value to Metabasis’ stockholders via the CVRs (which Metabasis is unable to independently realize due to its limited financial and operational resources);

Table of Contents
   

Financial Advisor’s Analysis and Fairness Opinion. The financial analysis prepared by Merriman and presented in its opinion to the Metabasis board of directors on October 26, 2009, that subject to the various qualifications and assumptions set forth in its opinion, the merger consideration is fair to Metabasis stockholders from a financial point of view (for a further discussion of the Merriman opinion, see “The Merger—Opinion of Metabasis’ Financial Advisor” beginning on page 55 of this proxy statement/prospectus);

 

   

Negotiations with Ligand. The course of extensive arm’s-length negotiations and discussions with Ligand, and improvements to the terms of the draft definitive transaction agreements in connection with and as a result of those negotiations and discussions, and the Metabasis board of directors’ belief based on those negotiations and discussions that the terms set forth in the final definitive transaction agreements were the most favorable terms to Metabasis and its stockholders to which Ligand was willing to agree;

 

   

CVR Consideration. The fact that the CVRs are generally tradable and represent further potential upside beyond the upfront merger consideration;

 

   

Stockholders’ Representative. The fact that the merger agreement provides for a stockholders’ representative to, among other things, monitor fulfillment of Ligand’s guaranteed funding obligations under the merger agreement, confirm satisfaction of Ligand’s obligations under the CVR agreements, and negotiate and enforce (or settle) matters with respect to the amounts to be paid to the holders of CVRs;

 

   

Ability to Respond to Unsolicited Proposal. The ability of the Metabasis board of directors, under certain circumstances specified in the merger agreement, to consider and respond to an unsolicited bona fide acquisition proposal from a third party before obtaining the approval of Metabasis stockholders of the merger, and the ability of the Metabasis board of directors to terminate the merger agreement to accept a superior proposal (as such term is defined in the merger agreement) upon the payment to Ligand of a termination fee of $400,000;

 

   

Ability to Withdraw or Change Recommendation. The ability of the Metabasis board of directors, under the merger agreement, to withdraw or modify, in a manner adverse to Ligand, its recommendation in favor of the adoption of the merger agreement and approval of the merger, after providing Ligand five days written notice of its intention to do so, if the Metabasis board of directors concludes in good faith, after the receipt of advice of outside legal counsel that a failure to take such actions would be inconsistent with its fiduciary duties under applicable law, subject to payment of a $400,000 termination fee to Ligand if, as a result, Ligand terminates the merger agreement within the time specified in the merger agreement;

 

   

Absence of Financing Condition or Ligand Stockholder Vote. The fact that completion of the merger and the other transactions contemplated by the merger agreement is not conditioned on Ligand’s ability to obtain financing or an affirmative vote of its stockholders;

 

   

Other Terms of the Definitive Transaction Agreements. The parties’ respective representations, warranties and other covenants under the definitive transaction agreements, and the belief that the terms of such agreements, taken as a whole, are reasonable under the circumstances.

 

   

Voting Agreements. The voting agreements entered into by various Metabasis stockholders who collectively owned approximately 28.9% of the outstanding shares of Metabasis common stock as of October 26, 2009, which demonstrated their support for the transaction.

The Metabasis board of directors also identified and considered a number of uncertainties, risks and other potentially negative factors, including the following:

 

   

Effect of Failure to Complete Transactions. The amount of time required to complete the merger, the conditions to the closing of the merger (some of which are outside Metabasis’ control) and the risks

 

54


Table of Contents
 

and costs to Metabasis if the transactions contemplated by the merger agreement do not close, including the effect on business relationships and the incurrence of significant transaction-related expenses, and the fact that if such transactions are not consummated and Metabasis is unable to secure additional resources, including through another strategic transaction, it will be required to cease operations entirely;

 

   

CVR Risks. The risk that the CVRs may yield little or no value for Metabasis stockholders or that transactions which would trigger payments pursuant to the CVRs do not occur before the applicable outside dates, thereby causing Metabasis stockholders not to receive value that could otherwise be obtained from the CVRs (and the fact that the holders of the CVRs will generally have no control over the specific research, development, sale and partnering activities undertaken by Ligand, which will themselves be subject to significant product and business development risks), and the risk that a liquid market will never develop for the CVRs, or that holders of the CVRs will not be able to trade such CVRs on acceptable terms if desired;

 

   

Interim Restrictions on Business. The potential impact of the restrictions under the merger agreement on Metabasis’ ability to take certain actions during the period before the effective time of the merger (which could delay or prevent Metabasis, other than with the consent of Ligand, from undertaking business opportunities that may arise pending completion of the merger);

 

   

Impact on Alternative Transactions. Certain provisions of the merger agreement may have the effect of discouraging proposals for alternative acquisition transactions involving Metabasis, including: (i) the restriction on Metabasis’ ability to solicit proposals for alternative transactions and (ii) the requirement that Metabasis pay a termination fee of up to $400,000 to Ligand in certain circumstances following the termination of the merger agreement;

 

   

Interests of Executive Officers and Directors. The risks arising from the fact that Metabasis’ executive officers and directors have interests in the merger as individuals that are in addition to, or that are different from, the interests of Metabasis’ stockholders (for a further discussion of these interests, see “The Merger—Interests of Metabasis’ Executive Officers and Directors in the Merger” beginning on page 66 of this proxy statement/prospectus); and

 

   

Other Risks. Other risks commonly associated with transactions such as the merger, including risks associated with the business of Ligand, Metabasis and the combined company, including those described in the section of this proxy statement/prospectus entitled “Risk Factors” beginning on page 22 of this proxy statement/prospectus.

The foregoing discussion of the factors considered by the Metabasis board of directors is not intended to be exhaustive, but rather includes the material factors considered by the Metabasis board of directors in its consideration of the merger agreement and the merger. After considering these factors, the Metabasis board of directors concluded that the positive factors relating to the merger agreement and the merger outweighed the potential negative factors. In view of the wide variety of factors considered by the Metabasis board of directors, and the complexity of these matters, the Metabasis board of directors did not find it practicable to, and did not, quantify or otherwise assign relative weights to the foregoing factors. In addition, individual members of the Metabasis board of directors may have assigned different weights to various factors. The Metabasis board of directors approved and recommends the merger agreement and the merger based upon the totality of the information presented to and considered by it.

Opinion of Metabasis’ Financial Advisor

On October 26, 2009, Merriman Curhan Ford & Co., or Merriman, rendered its opinion to Metabasis’ board of directors that, as of October 26, 2009, and based upon and subject to the factors and assumptions set forth therein, the merger consideration to be received by the holders of Metabasis common stock pursuant to the merger agreement is fair from a financial point of view to such holders.

Table of Contents

The full text of the written opinion of Merriman, dated October 26, 2009, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex G to this proxy statement/prospectus and is incorporated by reference herein. Merriman provided its opinion for the information and assistance of Metabasis’ board of directors in connection with its consideration of the merger in the form of the merger agreement, dated as of October 26, 2009. Merriman did not provide information or assistance to Metabasis’ board of directors in connection with its consideration of the amendment to the merger agreement, dated as of November 25, 2009. The Merriman opinion is not a recommendation as to how any holder of Metabasis common stock should vote with respect to the merger or any other matter.

In arriving at its opinion, Merriman reviewed and considered such financial and other matters as it deemed relevant, including, among other things:

 

   

a draft of the merger agreement dated as of October 24, 2009 and drafts, dated as of October 24, 2009, of the CVR agreements;

 

   

certain financial information regarding Metabasis’ historical and projected financial performance provided by Metabasis’ management;

 

   

certain publicly available information concerning Metabasis;

 

   

interviews it conducted with members of current and former senior management concerning Metabasis’ business and prospects;

 

   

certain publicly available information regarding companies and transactions comparable to the transaction contemplated by the merger agreement; and

 

   

such other information, financial studies, analyses and investigations deemed relevant for purposes of the opinion.

In conducting its review and arriving at its opinion, Merriman, with Metabasis’ consent, assumed and relied, without independent investigation, upon the accuracy and completeness of all financial and other information provided by Metabasis or which was publicly available or was otherwise reviewed by Merriman. Merriman did not undertake any responsibility for the accuracy, completeness or reasonableness of, or independent verification of, such information. Merriman relied upon, without independent verification, the assessment of Metabasis’ management as to the existing products of Metabasis and the viability of, and risks associated with, the future products of Metabasis. In addition, Merriman did not conduct, or assume any obligation to conduct, any physical inspection of the properties or facilities of Metabasis. Merriman further relied upon Metabasis’ representation that all information provided to it by Metabasis was accurate and complete in all material respects. Merriman assumed that the financial information provided was prepared in good faith on a reasonable basis in accordance with industry practice, and that Metabasis’ management was not aware of any information or facts that would make any information provided to Merriman incomplete or misleading. Merriman expressed no opinion as to Metabasis’ financial forecasts or the assumptions on which they were based. Merriman expressly disclaimed any undertaking or obligation to advise any person of any change in any fact or matter affecting its opinion of which Merriman becomes aware after the date of its opinion.

Merriman did not make or obtain any independent evaluations, valuations or appraisals of the assets or liabilities of Metabasis, nor was Merriman furnished with those materials. Additionally, Merriman did not evaluate the solvency or fair value of Metabasis under any state or federal laws relating to bankruptcy, insolvency or similar matters. Merriman did not undertake an independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which Metabasis (or any of its affiliates) is or may be subject. Merriman, with Metabasis’ consent, expresses no opinion with respect to such legal matters. Merriman’s opinion addressed only the fairness, from a financial point of view, to the holders of Metabasis’ common stock of the consideration to be received by such holders pursuant to the merger. Merriman expressed no view as to any other aspect or implication of the merger agreement or any other agreement, arrangement or understanding entered into in connection with the transactions contemplated by the merger agreement or otherwise. Merriman’s opinion was necessarily based upon economic and market

conditions and other circumstances as they existed and could be evaluated by Merriman on the date of its opinion. It should be understood that although subsequent developments may affect its opinion, Merriman does not have any obligation to update, revise or reaffirm its opinion and Merriman expressly disclaims any responsibility to undertake any of the foregoing.

In rendering its opinion, Merriman assumed, in all respects material to its analysis, that the representations and warranties of each party contained in the merger agreement and the CVR agreements are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the merger agreement and the CVR agreements and that all conditions to the consummation of the transactions contemplated by the merger agreement will be satisfied without waiver thereof. Merriman assumed that the final form of the merger agreement and that the CVR agreements would be substantially similar to the drafts received by Merriman on October 24, 2009. Merriman assumed that all governmental, regulatory and other consents and approvals contemplated by the merger agreement and the CVR agreements would be obtained and that, in the course of obtaining any of those consents, no restrictions will be imposed or waivers made that would have an adverse effect on those contemplated benefits of the transactions contemplated by the merger agreement.

Merriman’s opinion does not constitute a recommendation to any stockholder as to how the stockholders should vote with respect to the proposed transactions or to take any other action in connection with the proposed transactions or otherwise. Merriman’s opinion does not imply any conclusion as to the likely value, price or trading range for the CVRs following consummation of the transactions contemplated by the merger agreement or otherwise, which may vary depending on numerous factors that generally influence the price of securities. Merriman’s opinion is limited to the fairness, from a financial point of view, of the consideration to be received by the holders of Metabasis common stock pursuant to the merger. Merriman expresses no opinion as to the underlying business reasons that may support the decision of the Metabasis board of directors to approve, or Metabasis’ decision to consummate, the transactions contemplated by the merger agreement or the relative merits of such transactions as compared to other business strategies or transactions that might be available to Metabasis. Merriman’s opinion does not address the fairness of the amount or the nature of any compensation to any of Metabasis’ officers, directors or employees, or any class of such persons, relative to the consideration to be provided to the consideration to be provided to the stockholders of Metabasis.

Table of Contents

The following is a summary of the principal financial analyses performed by Merriman to arrive at its opinion. Some of the summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data set forth in the tables without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses. Merriman performed certain procedures, including each of the financial analyses described below, and reviewed with the management of Metabasis the assumptions on which such analyses were based and other factors, including the historical and projected financial results of Metabasis.

Metabasis Valuation Analyses. Merriman analyzed the valuation of Metabasis using three different methodologies: stand-alone operations analysis; liquidation analysis; and the analysis of the transaction proposed herein, or the Ligand transaction analysis. The results of these analyses are described below.

Overview

In order to evaluate the expected value of the various CVR agreements included in the merger consideration and to compare those expected values to the expected value Metabasis could expect from either stand-alone operations or a liquidation, Merriman applied probability adjustments to management’s estimates of the ultimate payments that could be expected under Metabasis’ various drug development programs based on the development stage of the respective program. Based on publicly available industry standards, Merriman used the following probability adjustments:

 

Stage of Development

   Probability of
Success
 

Pre-clinical

   3-5

Phase 1

   10-20

Phase 2

   25-35

Phase 3

   65-75

Registration

   90-95

Stand-Alone Operations

Merriman performed a stand-alone operations analysis on Metabasis assuming Metabasis attempted to follow a “go it alone” strategy and seek to raise additional capital to fund its operations. In large part because Metabasis was unable to raise additional funds through the financing process undertaken by Metabasis’ exclusive placement agent from March through May 2009, Merriman reached the conclusion that a “go it alone” strategy was not a viable option due to a lack of sufficient funding from operations and a lack of available financing. Due to Metabasis’ negative cash flow and the failure of Metabasis to raise capital, Merriman did not perform a standard discounted cash flow analysis on Metabasis. The foregoing analysis was based on the following key assumptions:

 

   

Management’s estimate that Metabasis will have net liabilities of approximately $1.3 million (or $0.04 per share) as of December 31, 2009;

 

   

That estimate did not include the potential cost of liquidation, which management estimated would be an additional $800,000;

 

   

Metabasis’ prior unsuccessful attempts to obtain additional financing; and

 

   

Metabasis’ lack of sufficient funds for continued operation of the business.

Liquidation

Based on information provided to it by Metabasis management, Merriman determined the estimated amount of cash available to stockholders in an orderly liquidation of Metabasis and estimated the value of a potential HepDirect partnership and successful achievement of milestones associated with the existing Roche partnership in a liquidation of Metabasis. Merriman believed that, in a liquidation, if Metabasis was unable to successfully partner HepDirect and if the Roche milestones were not achieved, the most likely scenario was that stockholders would receive nothing for their shares. Merriman concluded that liquidation would have a maximum expected value of approximately $50.8 million, or $1.44 per share assuming a HepDirect partnership and receipt of milestones associated with the Roche partnership, and a minimum expected value of $(2.1 million), or $(0.06) per share.

The expected value of Metabasis assuming no partnerships was calculated as follows:

* Wind down costs estimated at $800,000 for illustrative purposes.

Assuming that a trustee was retained to collect payments associated with the successful achievement of milestones under the Roche agreement in a liquidation, and assuming a partnership for HepDirect, the combined partnerships would provide a maximum expected net present value of approximately $50.8 million (assuming a 6% discount rate), after excluding the following items:

 

   

$1.3 million in estimated net liabilities of Metabasis;

 

   

An estimated $1.5 million to be paid under Metabasis’ lease termination agreement;

 

   

$800,000 in estimated costs associated with the dissolution of Metabasis; and

 

   

An estimate that 2% of all milestone payments would be used to cover costs associated with a trustee.

Merriman advised the Metabasis board of directors, however, that the expected maximum value of $50.8 million was dependent on the clinical success of the Roche program and the successful partnership of HepDirect.

Ligand Transaction

Merriman concluded that the merger provided an expected maximum value of approximately $70.2 million, or $1.99 per share, assuming successful achievement of all CVR milestones, and a minimum expected value of

$1.8 million, or $0.05 per share. As a result, both the minimum and maximum expected values of the merger exceeded the minimum and maximum expected values of a liquidation of Metabasis. In addition, the merger provided stockholders with upfront proceeds estimated to be $1.8 million, or $0.05 per share.

Merriman reviewed the various CVR agreements to be entered into in connection with the merger by applying the probability of success estimates shown above to the values Metabasis management expected to be received by stockholders under the CVR agreements, discounted back to present value. Under this methodology, Merriman concluded that the expected maximum value of the CVR agreements would be approximately $68.4 million, or $1.94 per share, and that the expected minimum value would be $0. The following table summarizes the results of this analysis with the following assumptions (in thousands):

Estimated Value of CVR Constituents

   Glucagon    TR Beta    HepDirect    MB07133    DGAT-1

Per Share Value

   $ 0.97    $ 0.24    $ 0.54    $ 0.02    $ 0.03    $ 0.13

 

   

Based on management estimates as adjusted to incorporate the probability of success and discount rates as applied by Merriman;

 

   

Each estimate presents a best case scenario for each CVR;

 

   

Based on a diluted per share value using 35,332,118 shares as of October 23, 2009; and

 

   

Based on a deduction of $1.5 million ($975,000 risk adjusted) related to the lease termination agreement from an assumed first milestone payment related to MB11362.

The expected maximum value of the merger of approximately $70.2 million includes the expected maximum value of the CVR agreements of approximately $68.4 million and the upfront proceeds to stockholders provided by the merger of approximately $1.8 million.

Analysis of Precedent CVR Transactions. Merriman reviewed recent CVR transactions which are commonly used structures which bridge valuation gaps between a company’s current value and its expected future value. Few of the precedent transactions, however, have included a CVR which is registered and tradable, as are the CVRs to be issued in the merger. The following tables present comparable CVR transactions (dollar amounts in millions):

Merriman’s analyses of the Comparable Companies indicated that the merger provides Metabasis stockholders with the ability to realize value in a range comparable to developmental stage metabolic focused companies that are not operating in a distressed situation.

General. The foregoing summary does not purport to be a complete description of all the analyses performed by Merriman. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial analysis and the application of these methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to partial analysis or summary description. Merriman did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, notwithstanding the separate factors summarized above, Merriman believes, and has advised the Metabasis board of directors, that its analyses must be considered as a whole and that selecting portions of its analyses and the factors considered by it, without considering all analyses and factors, could create an incomplete view of the process underlying its opinion. In performing its analyses, Merriman made numerous assumptions with respect to industry performance, business and economic conditions and other matters, many of which are beyond the control of Metabasis and Ligand. These analyses performed by Merriman are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by such analyses. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses or securities may actually be sold. Accordingly, such analyses and estimates are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors. None of Metabasis, Ligand, Merriman or any other person assumes responsibility if future results are materially different from those projected. The analyses supplied by Merriman and its opinion were among several factors taken into consideration by the Metabasis board of directors in making its decision to enter into the merger agreement and should not be considered as determinative of such decision.

Merriman was selected by the Metabasis board of directors to render an opinion to the Metabasis board of directors because Merriman is a nationally recognized investment banking firm and is regularly engaged as a financial advisor in connection with mergers and acquisitions, underwritings and secondary distributions of securities and private placements. In the ordinary course of business, Merriman and its affiliates actively trade the securities of Metabasis and may actively trade the securities of Ligand for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. Merriman and its affiliates in the ordinary course of business may in the future provide commercial and investment banking services to Metabasis and Ligand and may in the future receive fees for the rendering of such services.

 

64


Table of Contents

Merriman acted as financial advisor to Metabasis in connection with the transaction and has received a fee of $150,000 from Metabasis, none of which was contingent upon the consummation of the merger, and is entitled to receive an additional financial advisory fee of $100,000, which is contingent upon the consummation of the merger. Metabasis has also agreed to indemnify Merriman against certain liabilities and to reimburse it for certain expenses in connection with its services. In the future, Merriman may also provide other financial advisory and investment banking services to Ligand and its affiliates for which Merriman would expect to receive compensation. In addition, in the ordinary course of its business, Merriman and its affiliates may actively trade securities of Ligand and Metabasis for its own account or the account of its customers and, accordingly, may at any time hold a long or short position in such securities.

Ligand’s Reasons for the Merger

In reaching its determination to approve the merger agreement and the merger, the Ligand board of directors considered numerous factors discussed with Ligand’s outside legal advisors and senior management, including the following positive factors and benefits of the merger, uncertainties, risks and other potentially negative factors:

 

   

The status of, potential of, and risks inherent in Metabasis’ drug development programs and certain other Metabasis assets;

 

   

The amount and form of consideration being offered to Metabasis’ stockholders;

 

   

The back-end-loaded nature of the merger structure, wherein Ligand will make a relatively small cash consideration payment at the time of the merger but share with the former Metabasis stockholders any ultimate sale, license, milestone and royalty payments with respect to Metabasis’ current drug development programs and certain other Metabasis assets;

 

   

The obligation, created by the merger agreement, for Ligand to spend at least $8,000,000 in the research and development of Metabasis’ current drug development programs (or else pay out the shortfall under the General CVR agreement);

 

   

The actual and potential liabilities and payment obligations that Metabasis, as a Ligand subsidiary, will be responsible for after the merger;

 

   

The absence of any financial recourse against Metabasis or its stockholders in the event Metabasis’ liabilities are greater than is believed at Closing;

 

   

The representations, warranties and covenants of the parties, and the conditions to the closing of the merger;

 

   

The right of Metabasis’ board of directors, in the event it were to receive any unsolicited superior third party acquisition proposal or proposals before the stockholder meeting to approve the merger, to consider and enter into negotiations regarding any such proposals; and

 

   

The termination and termination fee provisions of the merger agreement, which (among other things) entitle Metabasis’ board of directors to withdraw its recommendation of the merger and terminate the merger agreement in order to enter into an agreement for a superior proposal (as defined in the merger agreement) with a third party, subject to the payment by Metabasis of a “break-up” fee.

The foregoing discussion of the factors considered by the Ligand board of directors is not intended to be exhaustive. After considering these factors, the Ligand board of directors concluded that the positive factors relating to the merger agreement and the merger outweighed the potential negative factors. In view of the wide variety of factors considered by the Ligand board of directors, and the complexity of these matters, the Ligand board of directors did not find it practicable to, and did not, quantify or otherwise assign relative weights to the foregoing factors. In addition, individual members of the Ligand board of directors may have assigned different weights to various factors. The Ligand board of directors approved the merger agreement and the merger based upon the totality of the information presented to and considered by it.

Interests of Metabasis’ Executive Officers and Directors in the Merger

In considering the recommendation of Metabasis’ board of directors that you vote to adopt the merger agreement and approve the merger, you should be aware that some of Metabasis’ executive officers and directors may have economic interests in the merger that are different from, or in addition to, those of Metabasis’ stockholders generally. Metabasis’ board of directors was aware of and considered these interests, among other matters, in reaching its determination that the merger agreement and the transactions contemplated thereby, including the merger, are advisable for, and in the best interests of, Metabasis and its stockholders, in approving the merger agreement and the transactions contemplated thereby, including the merger, and in making its recommendation that Metabasis’ stockholders vote in favor of the adoption of the merger agreement. These interests include the following:

 

   

upon the occurrence of certain types of termination of employment before the effective time of the merger, certain current and recently-departed executive officers are entitled to receive severance benefits, including certain lump sum payments, continuation of medical coverage, and immediate vesting of stock options as more fully described below;

 

   

the surviving entity will maintain and honor all indemnification arrangements in place for all past and present directors and officers of Metabasis for acts or omissions occurring at or before the effective time of the merger;

 

   

the surviving entity will maintain and honor all indemnification provisions and exculpation provisions in favor of each present or former director and officer of Metabasis that is set forth in the certificate of incorporation or bylaws of Metabasis and the equivalent organizational documents of any Metabasis subsidiary in effect as of the date of the merger agreement;

 

   

the organizational documents of the surviving entity will contain provisions with respect to exculpation and indemnification that are at least as favorable to the past and present indemnified directors and officers of Metabasis as those contained in Metabasis’ certificate of incorporation and bylaws in effect as of the date of the merger agreement;

 

   

David F. Hale, Executive Chairman and Acting Principal Executive Officer of Metabasis, will be appointed Stockholders’ Representative of Metabasis and will receive compensation in connection therewith;

 

   

Ligand agreed to use commercially reasonable efforts to negotiate and agree to terms with as many as possible of Edgardo Baracchini, David Bullough, Glenn Dourado and Barry Gumbiner, to assist, in the role of consultants, and with such consulting to begin as of the effective time of the merger, in Ligand’s efforts toward selling or licensing the ‘7133 Program by the sixth-month anniversary of the effective time of the merger; provided, that Ligand shall not be required to provide more than $40,000 in the aggregate for the compensation of such consultants. Mr. Baracchini was Senior Vice President of Business Development of Metabasis until October 23, 2009, and Mr. Gumbiner was Vice President of Clinical Development and Chief Medical Officer of Metabasis until October 14, 2009;

 

   

Ligand agreed to assume Metabasis’ obligations under its agreement with Mark Erion, previously President, Chief Executive Officer and Chief Scientific Officer of Metabasis, to provide Mr. Erion with a $50,000 cash payment in the event that Ligand completes a transaction, including a licensing or sale transaction, with respect to the Glucagon Program; also, the merger agreement contemplates that Ligand must initiate research, development or commercialization efforts on the Glucagon Program and provide funding for such efforts;

 

   

Ligand will indemnify and hold harmless the present and former directors and officers of Metabasis against all liabilities arising out of the actions or omissions of such person’s service, including the advancement of certain expenses, for a period of six years following the effective time of the merger; and

 

66


Table of Contents
   

Metabasis intends to purchase a directors’ and officers’ insurance tail policy before the merger and the surviving entity will maintain such policy, which will cover those persons who are covered by Metabasis’ directors’ and officers’ insurance policy for events occurring before the effective time of the merger on terms no less favorable than those applicable to the current directors and officers of Metabasis for six years, subject to certain limitations.

Metabasis’ directors and officers have entered into voting agreement with Ligand which require them to vote in favor of the merger agreement and the merger. Please see “Certain Terms of the Merger Agreement-Voting Agreements” beginning on page 101 of this proxy statement/prospectus.

Certain Severance Benefits. Metabasis’ general policy has been for its executive officers to maintain severance agreements. All of the agreements provide for a varying combination of cash, continued insurance benefits, outplacement services and acceleration of vesting on outstanding stock option awards. The agreements Metabasis maintains with certain of its executive officers provide for the following compensation in the event of termination for reasons other than cause: (i) cash severance equal to 12 months salary plus a cash payment equal to the average of the prior three years’ bonus payments, (ii) accelerated vesting of 12 additional months of all unvested stock options and shares of restricted stock, (iii) continued group disability insurance, group life insurance and group health benefits for a period of up to 12 months with the option to convert the group disability and group life insurance policies into individual polices, and (iv) outplacement services for up to six months.

In addition, total severance compensation due to the officer may be adjusted downward to ensure the best after-tax benefit to the officer if any portion of the benefits paid would be nondeductible under section 280G of the Internal Revenue Code. In the event of a termination for reasons other than cause or as a result of a restructuring or reduction in force, or resignation for good reason, within 12 months following a change in control, the officers will be entitled to an acceleration of vesting of all unvested stock options and shares of restricted stock.

Good reason is generally defined within these agreements as the occurrence of any of the following events: demotion or significant reduction in responsibilities; reduction in total compensation outside of a company-wide compensation reduction; or relocation of principal place of work by a distance of 50 miles or more. Cause is generally defined within these agreements as the occurrence of any of the following events: significant or continuing failure to perform employment duties; gross misconduct or fraud; or conviction of, or plea of “guilty” or “no contest” to, a non-vehicular felony.

Edgardo Baracchini, previously Senior Vice President of Business Development of Metabasis, and Barry Gumbiner, previously Vice President of Clinical Development and Chief Medical Officer of Metabasis, were each recently terminated and received severance packages as described above.

Tran B. Nguyen is the only executive officer currently at Metabasis entitled to severance benefits upon termination; and he is likely to be terminated in connection with the merger as well, and as a result would be entitled to severance benefits similar to those set forth above with the addition of relocation benefits and a related tax grossup. As part of the merger agreement, Ligand has specifically agreed to assume all such severance benefits. The cost of such severance benefits shall be treated as a reduction of Metabasis’ net cash for purposes of calculating the cash consideration payable in the merger.

In addition to the severance benefits described above, Ligand has specifically agreed to assume Metabasis’ obligations under its agreement with Dr. Mark Erion, previously President, Chief Executive Officer and Chief Scientific Officer of Metabasis, to provide Dr. Erion with a $50,000 cash payment in the event that Ligand completes a transaction, including a licensing or sale transaction, with respect to the Glucagon Program.

Stockholders’ Representative. The Stockholders’ Representative fund will be funded, to cover the expenses and compensation of the Stockholders’ Representative, out of money otherwise payable to the Metabasis

stockholders in an initial amount of $150,000 and the fund will be augmented (to the extent such augmentation would not increase the fund to over $300,000) by 1% of any amounts that are otherwise payable to CVR holders under any of the CVR agreements or that are subtracted from such amounts to make or reimburse payments related to certain contingent liabilities. The Stockholders’ Representative will be paid $45,000 in annual compensation for providing services as such. In addition, the Stockholders’ Representative shall not be responsible for any loss suffered by, or liability of any kind to, the stockholders or holders of CVRs arising out of any act done or omitted by the Stockholders’ Representative in connection with the acceptance or administration of the Stockholders’ Representative’s duties, unless such act or omission involves gross negligence or willful misconduct.

Insurance and Indemnification of Metabasis Officers and Directors. For a period of six years following the effective time of the merger, Ligand will cause the surviving entity and its subsidiaries to fulfill and honor the obligations of Metabasis and its subsidiaries pursuant to each indemnification agreement, in effect on the date of the merger agreement, between Metabasis or any of its subsidiaries and each present or former director and officer of Metabasis and any indemnification provision and any exculpation provision in favor of each present or former director and officer of Metabasis that is set forth in the certificate of incorporation or bylaws of Metabasis and the equivalent organizational documents of any Metabasis subsidiary in effect as of the date of the merger agreement. The certificate of incorporation and bylaws of the surviving entity shall contain the provisions with respect to indemnification and exculpation from liability set forth in Metabasis’ certificate of incorporation and bylaws on the date of the merger agreement, and, from and after the effective time of the merger, such provisions shall not be amended, repealed or otherwise modified in any manner that could adversely affect the rights thereunder of any individual who is or was an officer or director of Metabasis at any time on or before the effective time of the merger.

Ligand will indemnify and hold harmless the present and former directors and officers of Metabasis against all liabilities arising out of the actions or omissions of such person’s service, including the advancement of certain expenses, for a period of six years following the effective time of the merger or for claims for which a written notice asserting such claim for indemnification before the sixth anniversary of the merger until such time as such claim is fully and finally resolved.

In addition, for a period of six years following the effective time of the merger, the surviving entity will maintain in effect the current level and similar scope of directors’ and officers’ liability insurance coverage, provided that the surviving entity shall not be obligated to expend in any one year an amount in excess of $60,000. If Metabasis purchases a customary “tail” prepaid policy on Metabasis’ D&O insurance policy, the entire cost shall be treated as a reduction of Metabasis’ net cash for purposes of calculating the cash consideration payable in the merger. If Metabasis does not purchase a customary “tail” prepaid policy on Metabasis’ D&O insurance policy, Metabasis’ net cash at closing shall be deemed reduced by $360,000, and Ligand will cause the surviving corporation to purchase such “tail” policy immediately following the merger. Ligand will cause the surviving corporation to maintain such “tail” policy in full force and effect and honor its obligations thereunder. Metabasis intends to purchase such directors’ and officers’ insurance tail policy before the merger and the surviving entity will maintain such policy, which will cover those persons who are covered by Metabasis’ directors’ and officers’ insurance policy for events occurring before the effective time of the merger on terms no less favorable than those applicable to the current directors and officers of Metabasis for six years, subject to certain limitations.

Metabasis Directors and Officers After Completion of the Merger. Upon completion of the merger, the directors and officers of Metabasis will have resigned, and Ligand will appoint Ligand personnel as the directors and officers of the surviving corporation.

Regulatory Filings and Approvals Required to Complete the Merger

Neither Ligand nor Metabasis is aware of any material governmental or regulatory requirements that must be complied with regarding the merger, other than the effectiveness of the registration statement of which this proxy statement/prospectus is a part and compliance with applicable provisions of Delaware law.

Delisting and Deregistration of Metabasis Common Stock

If the merger is completed, Metabasis common stock will be delisted from The NASDAQ Stock Market and deregistered under the Exchange Act, and will cease to be tradable. In addition, Metabasis will cease to be a reporting company under the Exchange Act.

Material United States Federal Income Tax Consequences of the Merger

The following is a summary of the material United States federal income tax considerations of the merger applicable to Metabasis stockholders. This summary is based upon existing United States federal income tax law, which is subject to change or differing interpretations (possibly with retroactive effect). Neither Metabasis nor Ligand has sought, nor will they seek, a ruling from the Internal Revenue Service, or IRS, regarding the federal income tax consequences of the merger. As such, there can be no assurance that the IRS will not take a contrary position regarding the tax consequences of the merger described in this discussion or that any such contrary position would not be sustained. This summary does not address all aspects of United States federal income taxation which may be relevant to particular Metabasis stockholders in light of their individual investment circumstances, such as stockholders subject to special tax rules (e.g., financial institutions, insurance companies, broker-dealers, and tax-exempt organizations) or to stockholders who acquired Metabasis common stock in connection with stock option, stock purchase or restricted stock plans or in other compensatory transactions, or as part of a straddle, hedge, conversion, constructive sale, or other integrated security transaction for United States federal income tax purposes, all of whom may be subject to tax rules that differ significantly from those discussed below.

This summary does not discuss any United States federal income tax considerations to Metabasis stockholders who are not “United States holders” (as defined below). If you are not a United States holder you should consult with your own tax advisor as to the United States federal, state and local tax laws and foreign tax laws with respect to the merger. In addition, this summary does not discuss any United States federal income tax considerations to Metabasis stockholders who exercise appraisal or dissenter’s rights under Delaware law. This summary is limited to Metabasis stockholders that hold their Metabasis common stock as a “capital asset” (generally, property held for investment) under the Internal Revenue Code (the “Code”). You are urged to consult your own tax advisors regarding the United States federal income tax considerations of the merger, as well as the effects of state, local, and foreign tax laws.

For purposes of this summary, a “United States holder” is a Metabasis stockholder that is, for United States federal income tax purposes, (i) an individual who is a citizen or resident of the United States; (ii) a corporation or other entity taxable as a corporation that is created in, or organized under the laws of, the United States or any state or political subdivision thereof or any other entity treated as a “domestic” corporation under the Code; (iii) an estate, the income of which is includible in gross income for United States federal income tax purposes regardless of its source; or (iv) a trust (A) the administration of which is subject to the primary supervision of a United States court and which has one or more United States persons who have the authority to control all substantial decisions of the trust or (B) that has otherwise elected to be treated as a United States person under the Code.

If a partnership holds Metabasis common stock, the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding Metabasis common stock, you should consult your tax advisor regarding the tax considerations of the merger.

This discussion is for general information only and should not be construed as tax advice. It is a summary and does not purport to be a comprehensive analysis or description of all potential United States federal income tax consequences of the merger. Metabasis and Ligand urge you to consult your tax advisor with respect to the particular United States federal, state, local or foreign tax consequences of the merger to you.

General

The receipt of the merger consideration by a United States holder in exchange for Metabasis shares will be a taxable transaction for United States federal income tax purposes. The amount of gain or loss a United States holder recognizes, and the timing and potentially the character of a portion of such gain or loss, depends in part on the United States federal income tax treatment of the CVRs, with respect to which there is substantial uncertainty.

Because of the CVRs, the receipt of the merger consideration may be treated as either a “closed transaction” or an “open transaction” for United States federal income tax purposes. There is no authority directly on point addressing whether a sale of property for, in whole or in part, contingent value rights with characteristics similar to the CVRs should be taxed as “open transactions” or “closed transactions” and such question is inherently factual in nature. Accordingly, holders are urged to consult their tax advisors regarding this issue. The installment method of reporting any gain attributable to the receipt of a CVR will not be available because Metabasis common stock is traded on an established securities market. The CVRs may be treated as debt instruments for United States federal income tax purposes. However as such treatment is unlikely, the discussion below does not address the tax consequences of such a characterization.

Ligand is currently of the view that applicable tax principles weigh more heavily in favor of “closed transaction” treatment, and accordingly currently intends to conduct its own actions consistently with “closed transaction” treatment, including cooperating with the exchange agent to send Form 1099-B’s to persons receiving CVRs in the merger. Ligand’s views and actions (and the fair market value figure ascribed by Ligand to the CVRs as of the time of the merger) are not dispositive of the tax treatment question and/or such fair market value and are not binding on the IRS as to the holder’s appropriate tax treatment and/or such fair market value.

The following sections discuss the possible tax treatment if the receipt of the merger consideration is treated as an open transaction or a closed transaction. Metabasis and Ligand urge you to consult your tax advisor with respect to the proper characterization of the receipt of the CVRs.

Treatment of Consideration Received Upon Consummation of the Merger

Treatment as Open Transaction. The receipt of the CVRs would generally be treated as an “open transaction” if the value of the CVRs cannot be “reasonably ascertained.” If the receipt of the merger consideration is treated as an “open transaction” for United States federal income tax purposes, a United States holder will generally recognize capital gain for United States federal income tax purposes upon consummation of the merger if and to the extent the amount of cash received exceeds such United States holder’s adjusted tax basis in the Metabasis common stock surrendered pursuant to the merger.

Subject to the Section 483 Rules discussed below, if the transaction is “open” for United States federal income tax purposes, the CVRs would not be taken into account in determining the holder’s taxable gain upon receipt of the merger consideration and a United States holder would take no tax basis in the CVRs, but would recognize capital gain as payments with respect to the CVRs are made or deemed made in accordance with the United States holder’s regular method of accounting, but only to the extent the sum of such payments (and all previous payments under the CVRs), together with the amount received upon consummation of the merger discussed above, exceeds such United States holder’s adjusted tax basis in the Metabasis common stock surrendered pursuant the merger.

Subject to the Section 483 Rules discussed below, if the transaction is “open” for Unites States federal income tax purposes, a United States holder who does not receive cumulative payments pursuant to the merger with a fair market value at least equal to such United States holder’s adjusted tax basis in the Metabasis common stock surrendered pursuant the merger, will recognize a capital loss in the year that the United States holder’s right to receive further payments under the CVRs terminates.

 

70


Table of Contents

Gain or loss recognized in the transaction must be determined separately for each identifiable block of Metabasis common stock surrendered in the merger (i.e., shares of Metabasis common stock acquired at the same cost in a single transaction). Any such gain or loss will be long-term if the Metabasis common stock is held for more than one year before such disposition. With respect to gain in taxable years commencing before January 1, 2011, the maximum long-term capital gain tax rate for an individual United States holder is 15%. For gain in taxable years after December 31, 2010, under current law the long-term capital gain rate for an individual United States holder is 20%. The deductibility of both long-term and short-term capital loss is subject to certain limitations.

Treatment as Closed Transaction. If the value of the CVRs can be “reasonably ascertained” the transaction should generally be treated as “closed” for United States federal income tax purposes, in which event a United States holder should generally recognize capital gain or loss for United States federal income tax purposes upon consummation of the merger equal to the difference between (x) the sum of (i) the fair market value of the CVRs received, and (ii) the amount of cash received, and (y) such United States holder’s adjusted tax basis in the Metabasis common stock surrendered pursuant the merger.

Basis and Holding Period. If the transaction is “closed” for United States federal income tax purposes, a United States holder’s initial tax basis in the CVRs will equal the fair market value of the CVRs on the date of the consummation of the merger. The holding period of the CVRs will begin on the day following the date of the consummation of the merger.

Future Payments on the CVRs

Treatment as Open Transaction. If the transaction is treated as an “open transaction,” a payment pursuant to a CVR to a United States holder of a CVR should be treated as a payment under a contract for the sale or exchange of Metabasis common stock to which Section 483 of the Code applies (the “Section 483 Rules”). Under the Section 483 Rules, a portion of the payments made pursuant to a CVR will be treated as interest, which will be ordinary income to the United States holder of a CVR. The interest amount will equal the excess of the amount received over its present value at the consummation of the merger, calculated using the applicable federal rate as the discount rate. The United States holder of a CVR must include in its taxable income interest pursuant to the Section 483 Rules using such United States holder’s regular method of accounting. The portion of the payment pursuant to a CVR that is not treated as interest under the Section 483 Rules will generally be treated as a payment with respect to the sale of Metabasis common stock, as discussed above.

Treatment as Closed Transaction. If the transaction is treated as a “closed transaction,” there is no direct authority with respect to the tax treatment of holding and receiving payments with respect to property similar to the CVRs. It is possible that payments received with respect to a CVR, up to the amount of the holder’s adjusted tax basis in the CVR, may be treated as a non-taxable return of a United States holder’s adjusted tax basis in the CVR, with any amount received in excess of basis treated as gain from the disposition of the CVR. Additionally, a portion of any payment received with respect to a CVR may constitute imputed interest or as ordinary income under the Section 483 Rules. If not treated as described above, payments with respect to a CVR may be treated as either (i) payments with respect to a sale of a capital asset, (ii) ordinary income or (iii) dividends.

Due to the legal and factual uncertainty regarding the valuation and tax treatment of the CVRs, you are urged to consult your tax advisors concerning the recognition of gain, if any, resulting from the receipt of the CVRs in the merger and the receipt of payments, if any, under the CVRs after the merger.

Information Reporting and Backup Withholding

Under United States federal income tax laws, the exchange agent appointed by Ligand will generally be required to report to a United States holder and to the IRS any payments made to a United States holder in exchange for Metabasis common stock in the merger, and may be required to “backup withhold” 28% of any such payment. In addition, payments pursuant to the CVRs may be subject to back-up withholding and

 

71


Table of Contents

information reporting. To avoid such backup withholding, a United States holder should provide the exchange agent or other applicable person a properly completed Form W-9 (or appropriate substitute form), signed under penalties of perjury, including such holder’s current Taxpayer Identification Number, or “TIN,” and other certifications. If the United States holder does not provide the exchange agent with a TIN and other required certifications, the exchange agent will backup withhold 28% of payments made to the holder (unless the holder is an exempt recipient as described in the next sentence and demonstrates this fact).

Certain United States holders (including, among others, corporations) are exempt from these backup withholding and reporting requirements. Exempt holders who are not subject to backup withholding should indicate their exempt status on a Form W-9 by entering their correct TIN, marking the appropriate box and signing and dating the W-9 in the space provided.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a United States holder’s United States federal income tax liability provided the required information is timely furnished to the IRS.

Anticipated Accounting Treatment

In accordance with generally accepted accounting principles in the United States, Ligand will account for the merger under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations, as amended. Under the acquisition method of accounting, the total estimated purchase price, calculated as described in Note 2 to the unaudited pro forma condensed combined financial statements included in this proxy statement/prospectus, is allocated to the net tangible and intangible assets of Metabasis based on their estimated fair values. Management has made a preliminary allocation of the estimated purchase price to the tangible and intangible assets acquired and liabilities assumed based on various preliminary estimates. A final determination of these estimated fair values, which cannot be made before the completion of the merger, will be based on the actual net tangible and intangible assets of Metabasis that exist as of the date of completion of the merger, and upon the final purchase price.

Appraisal Rights of Dissenting Metabasis Stockholders

In connection with the merger, record holders of Metabasis common stock who comply with the procedures summarized below will be entitled to appraisal rights if the merger is consummated. The following discussion is not a complete discussion of the law pertaining to appraisal rights under Section 262 of the Delaware General Corporate Law, or Section 262, and is qualified in its entirety by the full text of Section 262 which is attached to this proxy statement/prospectus as Annex F. The following summary does not constitute any legal or other advice, nor does it constitute a recommendation that Metabasis stockholders exercise their right to seek appraisal under Section 262. All references in Section 262 and in this summary to a “stockholder” are to the record holder of the shares of Metabasis common stock as to which appraisal rights are asserted. A person having a beneficial interest in shares of Metabasis common stock held of record in the name of another person, such as a broker, fiduciary, depositary or other nominee, must act promptly to cause the record holder to follow the steps summarized below properly and in a timely manner to perfect appraisal rights, or else those rights will be lost.

Under Section 262, holders of shares of Metabasis common stock who do not vote in favor of adoption of the merger agreement and the transactions contemplated thereby, including the merger, and who otherwise follow the procedures set forth in Section 262 will be entitled to have their shares appraised by the Delaware Court of Chancery and to receive payment of the “fair value” of the shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, as determined by the court. Metabasis stockholders should be aware that investment banking opinions as to the fairness from a financial point of view of the merger consideration are not opinions as to fair value under Section 262.

Table of Contents

Under Section 262, where a merger is to be submitted for approval at a meeting of stockholders, as in the case of the adoption of the merger agreement and approval of the merger, by Metabasis stockholders, the corporation, not less than 20 days before the meeting, must notify each of its stockholders entitled to appraisal rights that appraisal rights are available and include in the notice a copy of Section 262. This proxy statement/prospectus shall constitute the notice, and the full text of Section 262 is attached to this proxy statement/prospectus as Annex F. Any holder of Metabasis common stock who wishes to exercise appraisal rights or who wishes to preserve such holder’s right to do so, should review the following discussion and Annex F carefully because failure to timely and properly comply with the procedures specified will result in the loss of appraisal rights. Due to the complexity of the procedures for exercising the right to seek appraisal, Metabasis stockholders who are considering exercising such rights are urged to seek the advice of legal counsel.

Metabasis stockholders of record who desire to exercise their appraisal rights must satisfy all of the following conditions. They must:

 

   

hold of record shares of Metabasis common stock on the date the written demand for appraisal is made and continue to hold the shares of record through the effective time of the merger;

 

   

deliver to the Corporate Secretary of Metabasis, before the vote on the adoption of the merger agreement, a written demand for the appraisal of the stockholder’s shares; and

 

   

not vote such stockholder’s shares of common stock in favor of, or consent in writing to, the adoption of the merger agreement and the transactions contemplated thereby, including the merger.

Neither voting against the adoption of the merger agreement and approval of the merger (either in person or by proxy), nor abstaining from voting or failing to vote on the proposal to adopt the merger agreement and approve the merger, will in and of itself constitute a written demand for appraisal satisfying the requirements of Section 262. The written demand for appraisal must be in addition to and separate from any proxy or vote. The demand must reasonably inform Metabasis of the identity of the holder as well as the intention of the holder to demand an appraisal of the “fair value” of the shares held by the holder. A stockholder’s failure to make the written demand before the taking of the vote on the adoption of the merger agreement and approval of the merger at the Metabasis special meeting will constitute a waiver of appraisal rights.

Only a holder of record of shares of Metabasis common stock on the record date for the Metabasis special meeting is entitled to assert appraisal rights for the shares registered in that holder’s name. A demand for appraisal in respect of shares of Metabasis common stock should be executed by or on behalf of the holder of record, fully and correctly, as the holder’s name appears on the holder’s stock certificates, should specify the holder’s mailing address and the number of shares registered in the holder’s name, and must state that the person intends to demand appraisal of the holder’s shares pursuant to the merger agreement. If the shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of the demand should be made in that capacity. If the shares are owned of record by more than one person, as in a joint tenancy and tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including an agent for two or more joint owners, may execute a demand for appraisal on behalf of a holder of record. However, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, the agent is acting as agent for the record owner or owners. A record holder such as a broker who holds shares as nominee for several beneficial owners may exercise appraisal rights with respect to the shares held for one or more beneficial owners while not exercising the rights with respect to the shares held for other beneficial owners. In such case, however, the written demand should set forth the number of shares as to which appraisal is sought. If no number of shares is expressly mentioned, the demand will be presumed to cover all shares of Metabasis common stock held in the name of the record owner. Stockholders who hold their shares in brokerage accounts or other nominee forms and who wish to exercise appraisal rights are urged to consult with their brokers to determine the appropriate procedures for the making of a demand for appraisal by such a nominee.

Table of Contents

A Metabasis stockholder of record who elects to demand appraisal of his or her shares must mail or deliver his or her written demand to: Metabasis Therapeutics, Inc., 11119 North Torrey Pines Road, La Jolla, California 92037 Attention: Corporate Secretary. The written demand for appraisal should specify the stockholder’s name and mailing address, the number of shares owned, and that the stockholder is thereby demanding appraisal of his or her shares, and such written demand must be received by Metabasis before the special meeting.

In addition, a Metabasis stockholder who desires to exercise appraisal rights must not vote such stockholder’s shares of common stock in favor of adoption of the merger agreement and approval of the merger. A vote in favor of adoption of the merger agreement and approval of the merger, by proxy, via the Internet, or in person, will constitute a waiver of your appraisal rights and will nullify any previously filed written demands for appraisal. Because a proxy that is signed and does not contain voting instructions will, unless revoked, be voted in favor of adoption of the merger agreement and approval of the merger, a stockholder who votes by proxy and who wishes to exercise appraisal rights must vote against the merger agreement and approval of the merger, or abstain from voting on the merger agreement and approval of the merger.

Within 10 days after the effective time of the merger, Metabasis, which is referred to in the post-merger context as the surviving corporation, must notify each holder of Metabasis common stock who has complied with Section 262 and who has not voted in favor of the adoption of the merger agreement and approval of the merger, that the merger has become effective and shall include in such notice a copy of Section 262. Within 120 days after the effective time of the merger, the surviving corporation or any stockholder who has timely and properly demanded appraisal of his or her shares and who has complied with the required conditions of Section 262 and is otherwise entitled to appraisal rights may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares of all Metabasis stockholders who have properly demanded appraisal. The surviving corporation is under no obligation to and has no present intention to file a petition. Accordingly, it is the obligation of the eligible holders of Metabasis common stock to initiate all necessary action to perfect their appraisal rights in respect of shares of Metabasis common stock within the time prescribed in Section 262. Notwithstanding the foregoing, any Metabasis stockholder that has not commenced an appraisal proceeding or joined any such proceeding within 60 days following the merger shall have the right to withdraw such stockholder’s demand for appraisal and to accept the merger consideration. After this period, a stockholder may withdraw his, her or its demand for appraisal and receive payment for his, her or its shares as provided in the merger agreement only with the consent of the surviving corporation.

Within 120 days after the effective time of the merger, any holder of Metabasis common stock who has complied with the requirements for exercise of appraisal rights will be entitled, upon written request, to receive from the surviving corporation a statement setting forth the aggregate number of shares of Metabasis common stock not voted in favor of the adoption of the merger agreement and the transactions contemplated thereby, including the merger, and the aggregate number of shares that have made demands for appraisal. The statement must be mailed within 10 days after a written request has been received by the surviving corporation or within 10 days after the expiration of the period for delivery of demands for appraisal, whichever is later.

If a petition for an appraisal is timely filed by a holder of shares of Metabasis common stock and a copy is served upon the surviving corporation, the surviving corporation will then be obligated within 20 days to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreements as to the value of their shares have not been reached. After notice to the stockholders as required by the Court, the Delaware Court of Chancery is empowered to conduct a hearing on the petition to determine those stockholders who have complied with Section 262 and who have become entitled to appraisal rights thereunder. The Delaware Court of Chancery may require the stockholders who demanded payment for their shares to submit their stock certificates to the Register in Chancery for notation on the certificates of the pending appraisal proceeding. If any stockholder fails to comply with the direction, the Delaware Court of Chancery may dismiss the proceedings as to that stockholder.

 

74


Table of Contents

After determining the holders of Metabasis common stock entitled to appraisal, the Delaware Court of Chancery will determine the fair value of shares of the Metabasis common stock exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, to be paid upon the amount determined to be the fair value.

In determining fair value, and, if applicable, a fair rate of interest, the Delaware Court of Chancery is to take into account all relevant factors.

Metabasis stockholders considering seeking appraisal should bear in mind that the fair value of their shares of common stock as determined under Section 262 could be more than, the same as, or less than the merger consideration they are entitled to receive pursuant to the merger agreement if they do not seek appraisal of their shares, and that opinions of investment banking firms as to the fairness from a financial point of view of the merger consideration payable in a merger are not opinions as to fair value under Section 262.

The cost of the appraisal proceeding (which does not include attorneys’ fees or the fees or expenses of experts) may be determined by the Delaware Court of Chancery and levied upon the parties as the Delaware Court of Chancery deems equitable in the circumstances. Upon application of a stockholder seeking appraisal rights, the Delaware Court of Chancery may order that all or a portion of the expenses incurred by such stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts, be charged pro rata against the value of all shares entitled to appraisal. In the absence of such a determination of assessment, each party bears its own expenses.

Except as explained in the last sentence of this paragraph, at any time within 60 days after the effective time of the merger, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party will have the right to withdraw his or her demand for appraisal and to accept the merger consideration to which such stockholder is entitled pursuant to the merger. After this period, such holder may withdraw his or her demand for appraisal only with the consent of the surviving corporation. If no petition for appraisal is filed with the Delaware Court of Chancery within 120 days after the effective time of the merger, Metabasis stockholders’ rights to appraisal will cease and all Metabasis stockholders will be entitled only to receive the merger consideration as provided for in the merger agreement.

Failure to comply with all of the procedures set forth in Section 262 will result in the loss of a stockholder’s statutory appraisal rights. In view of the complexity of Section 262, stockholders who wish to dissent from the merger and pursue appraisal rights should consult their legal advisors before attempting to exercise such rights.

CERTAIN TERMS OF THE MERGER AGREEMENT

The following description of the merger agreement describes certain material terms of the merger agreement, the CVR agreements, and other transaction documents. The full text of the merger agreement and the forms of CVR agreements are attached as Annex A, Annex B, Annex C, Annex D and Annex E to this proxy statement/prospectus and are incorporated herein by reference. Metabasis stockholders are encouraged to read the entire merger agreement, CVR agreements and the other annexes to this proxy statement/prospectus.

The merger agreement, the CVR agreements and the other annexes attached to this proxy statement/prospectus were included to provide investors and security holders with information regarding their respective terms. These agreements are not intended to provide any other factual information about Ligand or Metabasis. The merger agreement and the forms of CVR agreements attached as annexes to this proxy statement/prospectus contain representations and warranties that the parties thereto made to, and solely for the benefit of, each other, and such representations and warranties may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. The assertions embodied in Metabasis’ representations and warranties in the merger agreement are qualified by information in a confidential disclosure letter that Metabasis delivered to Ligand in connection with the execution of the merger agreement. Accordingly, investors and security holders should not rely on the representations and warranties as characterizations of the actual state of facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the merger agreement which subsequent information may or may not be fully reflected in Ligand’s or Metabasis’ public disclosures.

The Merger

At the effective time of the merger, Ligand’s wholly-owned subsidiary, Moonstone Acquisition, Inc., or Merger Sub, will be merged with and into Metabasis, with Metabasis continuing as the surviving corporation. Upon completion of the merger, the directors and officers of Metabasis will have resigned, and Ligand will appoint Ligand personnel as the directors and officers of the surviving corporation.

Effective Time of the Merger

The merger agreement provides that the merger will become effective when a certificate of merger executed by Metabasis and Merger Sub is filed with the Secretary of State of the State of Delaware.

Manner and Basis of Converting Shares

The merger agreement provides that, at the effective time of the merger, each share of Metabasis common stock then outstanding (other than shares held by Ligand, Merger Sub or Metabasis or shares for which appraisal rights have been properly demanded) will automatically be converted into the right to receive:

 

   

a proportionate share of a closing cash payment equal to $3,207,500 less $150,000, which is to be contributed to an account to cover the costs, expenses and compensation of the Stockholders’ Representative, and either (i) plus the positive net cash (as defined in the merger agreement) of Metabasis at the closing of the merger or (ii) less the negative net cash (as defined in the merger agreement) of Metabasis at the closing of the merger;

any such cash received being referred to in this proxy statement/prospectus as the cash consideration; and

 

   

one Roche contingent value right, one TR Beta contingent value right, one Glucagon contingent value right, and one General contingent value right, each of which entitles the holder to a proportionate share of various contingent payments, payable upon certain events, which are referred to in this proxy statement/prospectus as the CVRs. See “—CVR Agreements” for a description of the conditions to be satisfied for the contingent payments. Each CVR will be issued in book-entry form only.

Table of Contents

The merger agreement defines Metabasis’ “net cash” as an amount calculated on the assumption that the merger has occurred and equal to (i) the sum of (a) all cash (including any payments received by Metabasis from the exercise of Metabasis stock options or warrants, cash equivalents, marketable securities and accounts receivable (net of accounts receivable reserves established as required by GAAP) held by Metabasis its subsidiaries (but excluding the Roche Program consideration and ‘7133 Program consideration, if any, received by Metabasis before the merger) and (b) all fees and expenses actually incurred by Metabasis in connection with any ‘7133 Program transaction that is consummated before the merger; minus (ii) the sum of (A) $360,000 if Metabasis has not before the merger purchased a “tail” prepaid policy on the director and officer insurance policy as contemplated by the merger agreement, (B) any amount payable by Metabasis for the out-of-pocket transaction fees and expenses of Metabasis to its legal and financial advisors and accountants in connection with the merger agreement and the merger-related transactions, (C) any amount payable by Metabasis for expenses incurred in connection with the preparation, filing, printing and mailing of this proxy statement/prospectus and the solicitation of proxies for use at the special meeting, (D) except as otherwise covered in item (E) below, all severance payments, stay bonuses and performance bonuses payable to all employees, consultants and directors of Metabasis and its subsidiaries assuming that the service relationship of all such employees, consultants and directors with Metabasis and its subsidiaries is terminated as of the closing date, even if such service relationship in fact does continue after the closing date, (E) all severance payments, stay bonuses and performance bonuses remaining payable at the closing date to all employees, consultants and directors of Metabasis and its subsidiaries whose service relationship with Metabasis and its subsidiaries is terminated on or before the effective time of the merger, (F) the salary, employer-tax and benefits cost of the continuation of employment of any Metabasis employees, as a result of the advance-notice requirements of their respective employment agreements, beyond the effective time of the merger until their actual termination date, if before the effective time of the merger Ligand requests Metabasis to terminate such employees, and (G) to the extent not included in any item, all accounts payable all accounts payable, notes payable, lease payables and other capital-item liabilities and other liabilities (other than (x) non-cash items, (y) any contingent payments payable in respect of post-merger transactions by Metabasis to Metabasis’ landlord ARE-SD Region No. 24, LLC or its affiliates or (z) any contingent severance payments payable in respect of post-merger transactions to the employees that were terminated in Metabasis’ May 2009 reduction in force) of Metabasis and its subsidiaries; provided that all such amounts shall be determined in a manner consistent with the manner in which such items were determined by Metabasis in the most recent balance sheet included in Metabasis’ financial statements. Metabasis intends to purchase a directors’ and officers’ insurance tail policy before the merger and the surviving entity will maintain such policy, which will cover those persons who are covered by Metabasis’ directors’ and officers’ insurance policy for events occurring before the effective time of the merger on terms no less favorable than those applicable to the current directors and officers of Metabasis for six years, subject to certain limitations.

Metabasis currently estimates the cash consideration payable to Metabasis stockholders at the closing to be approximately $1.8 million.

The cash consideration and the contingent value rights are collectively referred to in this proxy statement/prospectus as the merger consideration.

Under the terms of the merger agreement, promptly following the effective time of the merger, an exchange agent appointed by Ligand will mail to each record holder of Metabasis common stock a letter of transmittal and instructions for use, which record holders will use to exchange Metabasis common stock certificates for the merger consideration. Metabasis common stock certificates should not be surrendered for exchange by Metabasis stockholders before the effective time of the merger.

After the effective time of the merger, transfers of Metabasis common stock will not be registered on the stock transfer books of Metabasis, and each certificate that previously evidenced Metabasis common stock will be deemed to evidence the right to receive the merger consideration.

Stockholders’ Representative

David F. Hale will, after the effective time of the merger, act as the Stockholders’ Representative for purposes of the merger agreement and CVR agreements. The responsibilities of the Stockholders’ Representative shall be to take such actions as may be necessary or appropriate to accomplish the intent and implement the provisions of the merger agreement and the CVR agreements, and to facilitate the consummation of the transactions contemplated thereby, including to (a) negotiate and enforce (or settle) matters arising under the merger agreement, (b) accept delivery of notices, (c) monitor fulfillment of Ligand’s guaranteed funding obligations, (d) confirm satisfaction of Ligand’s obligations under the CVR agreements, (e) negotiate and enforce (or settle) matters with respect to the amounts to be paid to the holders of CVRs and (f) enter into binding amendments or waivers of the former stockholders’ and the CVR holders’ rights under the merger agreement and the CVR agreements; provided, that before the delivery of any funding objection notice or notice of objection (as defined in the CVR agreements) or the filing of any other litigation or arbitration action or dispute process of any kind, the Stockholders’ Representative shall first obtain the assent of at least 20% of the then outstanding General CVR holders, in the case of a funding objection notice, or at least 20% of the CVRs then outstanding under the applicable CVR agreement under which such notice of objection is to be delivered, in the case of a notice of objection.

The Stockholders’ Representative fund will be funded, to cover the expenses and compensation of the Stockholders’ Representative, out of money otherwise payable to the Metabasis stockholders in an initial amount of $150,000 and the fund will be augmented (to the extent such augmentation would not increase the fund to over $300,000) by 1% of any amounts that are otherwise payable to CVR holders under any of the CVR agreements or that are subtracted from such amounts to make or reimburse payments related to certain contingent liabilities. The Stockholders’ Representative will be paid $45,000 in annual compensation for serving as such. Following the last possible payment event under the General CVR agreement, any amounts remaining in the Stockholders’ Representative fund will be distributed to the holders of the CVRs upon the request of the holders of 20% of the General CVRs. In addition, the Stockholders’ Representative shall not be responsible for any loss suffered by, or liability of any kind to, the stockholders or holders of CVRs arising out of any act done or omitted by the Stockholders’ Representative in connection with the acceptance or administration of the Stockholders’ Representative’s duties, unless such act or omission involves gross negligence or willful misconduct.

To the extent permitted by applicable law, in no event shall any holders of CVRs (as opposed to the Stockholders’ Representative) or any former stockholders of Metabasis (as opposed to the Stockholders’ Representative) have, after the effective time of the merger, any power or right to commence or join in any claim (presented formally to a judicial or quasi-judicial governmental entity), lawsuit, court action, suit, arbitration or other judicial or administrative proceeding based on or arising out of any CVR agreement or the merger agreement.

In the event that the Stockholders’ Representative dies, becomes unable to perform his responsibilities or resigns from such position, the holders of at least 34% of the then outstanding General CVRs shall be authorized to and shall select another representative reasonably acceptable to Ligand to fill such vacancy and such substituted representative shall be deemed to be the Stockholders’ Representative for all purposes of the merger agreement and the CVR Agreements.

In the event that within 30 days after the Stockholders’ Representative dies, becomes unable to perform his responsibilities or resigns from such position, no successor Stockholders’ Representative reasonably acceptable to Ligand has been so selected, the rights agent shall forthwith notify the person or entity holding the largest quantity of the outstanding General CVRs (and who is not a competitor of Ligand) that such person or entity is the successor Stockholders’ Representative. If such person or entity notifies the rights agent, Ligand and the surviving corporation in writing that such person or entity declines to serve, the rights agent shall forthwith notify the person or entity holding the next-largest quantity of the outstanding General CVRs (and who is not a competitor of Ligand) that such next-largest-quantity person or entity is the successor Stockholders’ Representative. (And so on, to the extent as may be necessary.)

For a period of six years following the effective time of the merger, Ligand will cause the surviving entity and its subsidiaries to fulfill and honor the obligations of Metabasis and its subsidiaries pursuant to each indemnification agreement in effect on the date of the merger agreement between Metabasis or any of its subsidiaries and each present or former director and officer of Metabasis and any indemnification provision and any exculpation provision in favor of each present or former director and officer of Metabasis that is set forth in the certificate of incorporation or bylaws of Metabasis and the equivalent organizational documents of any Metabasis subsidiary in effect as of the date of the merger agreement. The certificate of incorporation and bylaws of the surviving entity shall contain the provisions with respect to indemnification and exculpation from liability set forth in Metabasis’ certificate of incorporation and bylaws on the date of the merger agreement, and, from and after the effective time of the merger, such provisions shall not be amended, repealed or otherwise modified in any manner that could adversely affect the rights thereunder of any individual who is or was an officer or director of Metabasis at any time on or before the effective time of the merger.

Ligand will indemnify and hold harmless the present and former directors and officers of Metabasis against all liabilities arising out of the actions or omissions of such person’s service, including the advancement of certain expenses, for a period of six years following the effective time of the merger or for claims for which a written notice asserting such claim for indemnification before the sixth anniversary of the merger until such time as such claim is fully and finally resolved.

In addition, for a period of six years following the effective time of the merger, Ligand will cause the surviving entity to maintain in effect the current level and similar scope of directors’ and officers’ liability insurance coverage, provided that the surviving entity shall not be obligated to expend in any one year an amount in excess of $60,000. In addition, before the merger, Metabasis may purchase a customary “tail” prepaid policy on Metabasis’ D&O insurance policy for a total premium not to exceed $360,000, or, in the alternative, Ligand will purchase such “tail” policy immediately following the merger (at Metabasis’ expense). Ligand will cause the surviving corporation to maintain such “tail” policy in full force and effect and honor its obligations thereunder. Metabasis intends to purchase a directors’ and officers’ insurance tail policy before the merger and the surviving entity will maintain such policy, which will cover those persons who are covered by Metabasis’ directors’ and officers’ insurance policy for events occurring before the effective time of the merger on terms no less favorable than those applicable to the current directors and officers of Metabasis for six years, subject to certain limitations.

Limitation on Metabasis’ Ability to Consider Other Acquisition Proposals

Metabasis has agreed that it shall not, and shall not authorize or permit Metabasis’ and Metabasis’ subsidiaries’, or any of their respective directors, officers, employees, investment bankers, attorneys and other agents or representatives to, directly or indirectly, not to:

 

   

solicit, initiate, knowingly encourage or knowingly induce the making, submission or announcement of an acquisition proposal;

 

   

furnish any non-public information relating to Metabasis in response to or in connection with an acquisition proposal;

 

   

participate or engage in discussions or negotiations with respect to an acquisition proposal; or

 

   

approve, endorse or recommend to the stockholders of Metabasis any acquisition proposal.

The foregoing restrictions do not prohibit Metabasis from engaging or participating in discussions or negotiations with any person that has made an acquisition proposal that the Metabasis board of directors determines in good faith constitutes or is reasonably likely to lead to a superior proposal, and in connection therewith furnishing to such party any non-public information relating to Metabasis and its subsidiaries pursuant to a confidentiality agreement, provided that the Metabasis board of directors shall first have determined in good faith that the failure to take such action is inconsistent with its fiduciary obligations to the stockholders of

Under the terms of the merger agreement, Metabasis has agreed to immediately cease and cause to be terminated any active discussions with any party (other than Ligand) that relate to any acquisition proposal.

Also, under the terms of the merger agreement, unless the Metabasis board of directors shall first have determined in good faith that the failure to take the following actions is inconsistent with its fiduciary obligations to the stockholders of Metabasis, Metabasis shall not release or permit the release of any party from, or waive or permit the waiver of any provision of, any confidentiality, standstill or similar agreement to which Metabasis is a party or under which Metabasis has any rights.

For purposes of the merger agreement, the term “acquisition transaction” means any transaction or series of related transactions (other than the transactions contemplated by the merger agreement) involving or resulting in: (i) any acquisition or purchase by any person or “group” (as defined in or under Section 13(d) of the Exchange Act), directly or indirectly, of more than 20% of the total outstanding voting securities of Metabasis, or any tender offer or exchange offer that, if consummated, would result in the person or “group” (as defined in or under Section 13(d) of the Exchange Act) making such offer beneficially owning more than 20% of the total outstanding voting securities of Metabasis; (ii) any merger, consolidation, share exchange, business combination, acquisition of securities, recapitalization, tender offer, exchange offer or other similar transaction involving Metabasis pursuant to which the stockholders of Metabasis immediately before the consummation of such transaction would hold less than 80% of the equity interests in the surviving or resulting entity of such transaction immediately after consummation thereof; or (iii) any sale (other than the sale of laboratory equipment), lease, exchange, transfer, license, acquisition or disposition of assets (other than the ‘7133 Program) constituting more than 10% of the assets of Metabasis (measured by either book or fair market value thereof) or the net revenues or net income of Metabasis and its subsidiaries taken as a whole.

For purposes of the merger agreement, the term “superior proposal” means any unsolicited, bona fide written offer made by a third party unaffiliated with Metabasis to directly or indirectly acquire (by way of merger, tender or exchange offer or otherwise) greater than 95% of Metabasis’ assets or greater than 95% of the outstanding Metabasis common stock (other than Metabasis common stock already held by such third party) that the Metabasis board of directors shall have determined in good faith (after consultation with Metabasis’ outside legal counsel and financial advisor, and after taking into account, among other things, the financial, legal and regulatory aspects of such offer (including any financing required and the availability thereof), as well as any revisions to the terms of the merger agreement proposed by Ligand, is more favorable from a financial point of

Obligations of the Metabasis Board of Directors with Respect to its Recommendation and Holding a Meeting of Stockholders

Metabasis agreed to duly set a record date for, call and establish a date for, and give notice of, a special meeting (with the record date and meeting date each set for a date as soon as reasonably practicable and in consultation with Ligand), and convene and hold the special meeting as soon as reasonably practicable after the date on which the registration statement becomes effective. This is the same special meeting to which this proxy statement/prospectus relates.

Under the terms of the merger agreement, Metabasis has also agreed that its board of directors will recommend that Metabasis stockholders vote to adopt the merger agreement. However, at any time before the approval of the Metabasis stockholders to adopt the merger agreement, Metabasis’ board of directors is entitled to withdraw or modify its recommendation that Metabasis stockholders vote to adopt the merger agreement if certain requirements, including either of the following, are satisfied:

 

   

(i) An acquisition proposal that constitutes a superior proposal has been made and not withdrawn, (ii) Metabasis’ board of directors determines in good faith that the failure to effect a change in recommendation in light of such superior proposal is inconsistent with its fiduciary obligations to the Metabasis stockholders under applicable law, (iii) Metabasis shall have given Ligand at least five days’ prior written notice advising Ligand that Metabasis’ board of directors has received a superior proposal, specifying the material terms and conditions of such superior proposal, including a copy of such superior proposal and identifying the party making such superior proposal and stating that it intends to modify or withdraw its recommendation that Metabasis stockholders adopt the merger agreement, (iv) during the five day period following Ligand’s receipt of a notice of recommendation change, Metabasis shall have given Ligand the opportunity to meet with Metabasis, and at Ligand’s request, shall have negotiated in good faith regarding the terms of possible revisions to the terms of the merger agreement and (v) Ligand shall not, within five days following Ligand’s receipt of a notice of recommendation change, have made an offer that the Metabasis board of directors determines in good faith (after consultation with its outside legal counsel and financial advisor) to be at least as favorable to the stockholders of Metabasis as such superior proposal; or

 

   

other than in connection with a superior proposal, (i) the Metabasis board of directors determines in good faith that the failure to effect a change in recommendation is inconsistent with its fiduciary obligations to the stockholders of Metabasis under applicable law, (ii) at least five days before such change in recommendation, Metabasis shall have provided to Ligand a notice of its intention to make such change in recommendation, specifying in reasonable detail the circumstances for such proposed change in recommendation, and (iii) during the five day period following Ligand’s receipt of a notice of recommendation change, Metabasis shall have given Ligand the opportunity to meet with Metabasis, and at Ligand’s request, shall have negotiated in good faith regarding the terms of possible revisions to the terms of the merger agreement.

Under the terms of the merger agreement, Metabasis’ obligation to call, give notice of, convene and hold the special meeting of Metabasis stockholders will not be limited or otherwise affected by the commencement, disclosure, announcement or submission to Metabasis of an acquisition proposal or by any withdrawal or modification of the recommendation by Metabasis’ board of directors that Metabasis stockholders vote to adopt the merger agreement. Metabasis is also not permitted to submit to the vote of its stockholders any acquisition proposal unless the merger agreement has been terminated by Metabasis in accordance with its terms. See “—Termination of the Merger Agreement.”

The merger agreement provides that, if Ligand terminates the merger agreement because Metabasis’ board of directors withdraws or modifies its recommendation that Metabasis stockholders vote to adopt the merger agreement, Metabasis will be required to pay Ligand the termination fee.

In addition, the merger agreement provides that Metabasis may terminate the merger agreement:

 

   

if the Metabasis board of directors authorizes Metabasis, subject to complying with the terms of the merger agreement, to accept (or to enter into a written agreement for a transaction constituting) a superior proposal; provided that immediately before (or contemporaneous with) such termination of the merger agreement, Metabasis shall pay to Ligand the termination fee payable pursuant to the merger agreement; or

 

   

if: (i) the representations and warranties of Ligand or Merger Sub set forth in the merger agreement shall not be true and correct on and as of the date of such determination as if made on such date (other than those representations and warranties that address matters only as of a particular date, which shall be true and correct as of such date), except where the failure of any such representation or warranty to be true and correct (without giving effect to any material adverse effect on Ligand or other materiality qualifications set forth therein) would not, individually or in the aggregate, reasonably be expected to have a material adverse effect or impair in any material respect the ability of Ligand or Merger Sub to perform their obligations under the merger agreement; or (ii) Ligand or Merger Sub shall have, in any material respect, breached or failed to perform or comply with any obligation, agreement or covenant required by the merger agreement to be performed or complied with by them it; and such breach or failure is not cured, or is incapable of being cured, on or before the outside date.

if Ligand terminates the merger agreement as a result of (i) Metabasis’ representations and warranties not being true and correct, except where the failure of any such representation or warranty to be true and correct would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on Metabasis or impair in any material respect the ability of Metabasis to perform its obligations under the merger agreement or the ability of Ligand to enjoy in all material respects the intended benefit of the merger and the transactions contemplated thereby; or (ii) Metabasis’ material breach or failure to perform or comply with any obligation, agreement or covenant required by the merger agreement.

Fees and Expenses

The merger agreement provides that, whether or not the merger is consummated, each party shall pay its own expenses incident to preparing for, entering into and carrying out the merger agreement and the transactions contemplated thereby. Nothing contained in the merger agreement shall be deemed to limit the right or ability of any party to the merger agreement to pay such expenses, as and when due and payable.

Amendment

The merger agreement may be amended by the parties thereto at any time before the effective time of merger provided that after the adoption of the merger agreement by Metabasis’ stockholders, no amendment shall be made which by law or in accordance with the rules of any relevant stock exchange requires further approval by the stockholders of Metabasis, without such further stockholder approval.

CVR Agreements

In connection with the closing of the merger, Ligand, Metabasis and a rights agent to be determined will enter into separate contingent value rights agreements relating to (i) Metabasis’ 2008 collaboration and license agreement with Roche for a partnered drug development program in hepatitis C, substantially in the form of the contingent value rights agreement included in this proxy statement/prospectus as Annex B (the “Roche CVR agreement”), (ii) Metabasis’ program for the development of a thyroid receptor beta agonist for the treatment of hyperlipidemia, or TR Beta Program, substantially in the form of the contingent value rights agreement included in this proxy statement/prospectus as Annex C (the “TR Beta CVR agreement”), (iii) Metabasis’ program intended to create a glucagon receptor antagonist drug for the treatment of diabetes, or Glucagon Program, substantially in the form of the contingent value rights agreement included in this proxy statement/prospectus as Annex D (the “Glucagon CVR agreement”), and (iv) funding shortfall payment rights pursuant to the merger agreement, Metabasis’ common stock and commercial interests related to privately-held PeriCor Technologies, Inc., and Metabasis’ other existing development programs and technologies, including Metabasis’ program for the development of diacylglycerol acyltransferase-inhibitors for the treatment of obesity and other metabolic diseases, or DGAT-1 Program, Metabasis’ program for the development of fructose-1,6-bisphosphatase inhibitors for the treatment of diabetes, or FBPase Inhibitor Program, Metabasis’ program for the development of glucose kinase activators for the treatment of type 2 diabetes and other metabolic diseases, or GK Program, Metabasis’ program for the development of pradefovir for the treatment of patients with hepatitis B, or Pradefovir Program, Metabasis’ program intended to create a liver-specific drug targeting technology for chemically modifying the molecule to render it inactive until the modification is cleaved off by a liver-specific enzyme, or HepDirect Program, and Metabasis’ program intended to create a HepDirect prodrug of AraCMP for the treatment of hepatocellular carcinoma, or the ‘7133 Program, substantially in the form of the contingent value rights agreement included in this proxy statement/prospectus as Annex E (the “General CVR agreement”). Annex B, Annex C, Annex D and Annex E are each incorporated by reference into this proxy statement/prospectus. The following summary describes the material provisions of the contingent value rights agreements. This summary may not contain all of the information about the contingent value rights agreements that is important to you. You are encouraged to read the forms of contingent value rights agreements carefully in their entirety because when entered into among Ligand, Metabasis, the Stockholders’ Representative and the rights agent, these documents will be the legal documents governing the contingent value rights to be issued to former

Metabasis securityholders in connection with the merger. Although the definitive version of the contingent value rights agreements negotiated and entered into with the chosen rights agent is not expected to differ from the form of contingent value rights agreements included with this proxy statement/prospectus in any respect that would be material to holders of contingent value rights, there can be no assurance that any changes will not, in fact, be material to holders.

At the closing of the merger, Ligand, Metabasis, the Stockholders’ Representative and a rights agent will enter into the contingent value rights, or CVR, agreements, the forms of which are attached as Annex B, Annex C, Annex D and Annex E to this proxy statement/prospectus. The CVR agreements set forth the rights that former Metabasis securityholders will have with respect to each CVR to be held by them after the closing of the merger.

Table of Contents

Specifically, with regard to the shortfalls from guaranteed funding obligations, Ligand agreed to, before the first anniversary of the merger, spend at least $350,000 on at least one of the drug research and/or development programs conducted before the merger by Metabasis, including the DGAT-1 Program, FBPase Inhibitor Program, GK Program HepDirect Program and Pradefovir Program (but not including the TR Beta Program, the Glucagon Program and the ‘7133 Program); provided, however, that if Ligand does not so spend at least $350,000, the difference between $350,000 and the amount spent as of such anniversary date on the one of those programs with the greatest spending will be distributed pursuant to the General CVR agreement, subject to the certain adjustments mentioned above, unless the Stockholders’ Representative, with the written consent of the holders of at least 20% of the General CVRs, consents to negate such requirement. Ligand also agreed to spend, before the 30th-month anniversary of the merger, an aggregate of at least $7,000,000 (inclusive of the previously-mentioned $350,000) on the Metabasis drug development programs (not limited to the five Programs specified in the previous sentence); provided, however, that if Ligand does not spend an aggregate of $7,000,000, the difference between $7,000,000 and the amount spent as of such 30th-month anniversary date will be distributed pursuant to the General CVR agreement, subject to the certain adjustments mentioned above, unless (i) the Stockholders’ Representative, with the written consent of the holders of at least 20% of the General CVRs, consents to negate such requirement, (ii) Ligand provides the Stockholders’ Representative with reasonable evidence that Ligand has entered into a partnering agreement with a third party to commercialize one of the Metabasis drug development programs and such agreement has a value of at least $100,000,000 in upfront and milestone proceeds or (iii) Ligand provides the Stockholders’ Representative with reasonable evidence that Ligand has ceased funding the TR Beta Program and the Glucagon Program. Finally, Ligand also agreed to spend, before the 42nd-month anniversary of the merger, an aggregate of at least $8,000,000 (inclusive of the previously-mentioned $350,000 and $7,000,000) on the Metabasis drug development programs (not limited to the four Programs specified in the next previous sentence), with the difference between $8,000,000 and the amount spent as of such anniversary date to be distributed pursuant to the General CVR agreement, subject to the certain adjustments mentioned above, unless the Stockholders’ Representative, with the written consent of the holders of at least 20% of the General CVRs, consents to extend such 42-month period an extra six months.

For the above purposes, the following shall be deemed to have been spent by Ligand: (i) 100% of reasonable out-of-pocket expenses paid to third parties by Ligand or the surviving corporation for goods or services actually provided after the effective time of the merger, or which is an account payable of Ligand or the surviving corporation for goods or services actually provided after the effective time of the merger, in each case which relates directly to the research and development of such drug development programs (including, without limitation, equipment, supplies, outsource firms, patent attorneys, filing fees, etc.); (ii) $350,000 per one year full time equivalent effort (1,875 hours per year of scientific work) of one scientist with either a B.Sc., M.S. or Ph.D. or equivalent degree, or FTE (plus a proportional amount per fractional FTE) working on or directly related to and in support of such programs; and (iii) any previous shortfall amount paid under the General CVR agreement. The $350,000 per FTE figure was specifically negotiated, and is intended to cover allocations of overhead and benefits.

The holders of General CVRs can, as to certain actions, exercise rights which control all four types of CVRs, without any corresponding right in the holders of the other three types of CVRs. Before the delivery of any funding objection notice or notice of objection (as defined in the CVR agreements), other than a notice of objection directly pertaining to the Roche CVR agreement, the TR Beta CVR agreement or the Glucagon CVR agreement, or the filing of any other litigation or arbitration action or dispute process of any kind, the Stockholders’ Representative must first obtain the assent of holders of at least 20% of the then outstanding General CVRs. Also, if the Stockholders’ Representative dies, becomes unable to perform his responsibilities or resigns from such position, it is the holders of at least 34% of the then outstanding General CVRs who can select another representative reasonably acceptable to Ligand to fill such vacancy and such substituted representative shall be deemed to be the

Table of Contents

Stockholders’ Representative for all purposes of the merger agreement and the CVR agreements. And, it is the holders of 20% of the General CVRs who can request the early distribution, to all holders of CVRs pro rata, of any amounts remaining in the Stockholders’ Representative fund.

CVR Transfers

The CVRs may be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, but only in accordance with the provisions of the CVR agreements regarding procedures for transfer and in compliance with applicable United States federal and state securities laws. Ligand is not obligated to, and is not currently expected to, list the CVRs for trading on any securities exchange or quotation system.

Reduction of CVR Payments to Satisfy or Reimburse Contingent Liability Payments to Third Parties

Metabasis has contingent liabilities of up to $1.5 million to its landlord ARE-SD Region No. 24, LLC. In July 2009, Metabasis terminated its lease for its corporate headquarters facility, and obtained a continued occupancy right through January 2, 2010; the consideration Metabasis gave in the transaction included contingent cash payments to be made based upon gross revenues or proceeds actually received by Metabasis pursuant to licenses, collaboration arrangements or sales of Metabasis’ existing pipeline of therapeutic programs by September 30, 2010. ARE-SD would be entitled to receive contingent liability payments equal to 35% of such gross revenues or proceeds actually received by Metabasis, up to a total cash payment of $1.5 million to ARE-SD.

Metabasis also has contingent liabilities of up to an aggregate of approximately $1.15 million for contingent cash severance payments to the employees who were terminated in Metabasis’ May 2009 reduction in force. These contingent severance payments are triggered if Metabasis receives at least $10 million in the aggregate from the sale or license of its intellectual property assets, including the receipt of milestone payments from Roche, before May 26, 2010. If Metabasis receives $10 million before May 26, 2010 from the sale or license of its intellectual property assets then Metabasis has the obligation to pay an amount equal to 46 days’ salary at the respective employee’s salary rate at the time of termination. If the sale or license of intellectual property results in proceeds of $20 million before May 26, 2010, Metabasis has the obligation to make additional cash payments equal to a certain additional number of days’ salary (depending on the employee) at the employee’s respective salary rate at the time of termination.

In general, events which would give rise to payments of the contingent liabilities described in the two preceding paragraphs, or the contingent liability payments, would also give rise to payments under one of the CVRs. Each CVR agreement provides that any contingent liability payments are to be satisfied first from amounts otherwise payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such payment event, but in some instances the full amount payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such payment event will be less than the contingent liability payments owing in respect of such payment event.

In the event of such a shortfall, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such payment event will be paid by Ligand directly to the beneficiaries of the contingent liability payments rather than to or for the benefit of the holders of the CVRs under the applicable CVR agreement, and the remainder of the contingent liability payments owing in respect of such payment event, or the excess, shall be paid by Ligand directly to the beneficiaries of the contingent liability payments. Then, then upon the next payment event under any of the CVR agreements (even if not the same CVR agreement in connection with which the excess was paid), Ligand shall withhold from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR agreement in respect of such (new) payment event, and shall keep for Ligand’s own account to reimburse Ligand for having paid the excess, an amount equal to 100% of the excess (or, if less, 100% of the amount otherwise payable for the benefit of the

 

97


Table of Contents

holders of the CVRs under the applicable CVR agreement in respect of such (new) payment event). If Ligand is not thereby reimbursed for the entire excess, the shortfall shall be rolled forward to be satisfied in the same manner by withholding from any amount otherwise payable for the benefit of the holders of CVRs in respect of the next-to-occur payment event under any of the CVR agreements (even if not the same CVR agreement in connection with which the excess was paid or in connection with which the excess was partially satisfied).

As noted, it is possible that an excess that arises because of a CVR payment triggering event that triggers payments under only one type of CVRs may be satisfied from a next-to-occur payment(s) arising under another type or types of CVRs. In such a case, the CVRs which satisfy the excess will have no recourse against the CVRs which created the excess, even if other payment events and payments later occur under the CVRs which created the excess.

It is also true that because reductions to satisfy up to the entire amount of all contingent liability payments ever payable may be made entirely or disproportionately from early-occurring payment events arising under one or more particular CVR agreements, holders of that type of CVRs would be disadvantaged in comparison to the holders of other types of CVRs if the other types of CVRs have later-occurring payment events. Payments under such other types of CVRs would not have to be reduced to satisfy contingent liability payments, if all contingent liability payments ever payable have already been satisfied.

Ligand’s Sole Discretion and Decision Making Authority

The CVR agreements provide:

 

   

in the case of the Roche CVR agreement, that Ligand shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, with respect to the Roche Agreement;

 

   

in the case of the TR Beta CVR agreement, that Ligand shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, over any continued operation of, development of or investment in the TR Beta Program and over when (if ever) and whether to pursue, or enter into, a licensing agreement and/or sale agreement and/or similar transfer agreement and/or agreement for the grant of an option to enter into any such transaction with respect to a drug candidate or technology or intellectual property from the TR Beta Program, and upon what terms and conditions;

 

   

in the case of the Glucagon CVR agreement, that Ligand shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, over any continued operation of, development of or investment in the Glucagon Program and over when (if ever) and whether to pursue, or enter into, a licensing agreement and/or sale agreement and/or similar transfer agreement and/or agreement for the grant of an option to enter into any such transaction with respect to a drug candidate or technology or intellectual property from the Glucagon Program, and upon what terms and conditions; and

 

   

in the case of the General CVR agreement, that Ligand shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, over any continued operation of, development of or investment in any or all of the drug research and/or development programs conducted by Metabasis before the merger (including without limitation the DGAT-1 Program, FBPase Inhibitor Program, GK Program, HepDirect Program and Pradefovir Program) other than those programs explicitly covered by the other CVR agreements, and over when (if ever) and whether to pursue, or enter into, a licensing agreement and/or sale agreement and/or similar transfer agreement and/or agreement for the grant of an option to enter into any such transaction with respect to a drug candidate or technology or intellectual property from any or all of such programs, the ‘7133 program or the QM/MM program, and upon what terms and conditions.

 

98


Table of Contents

Each CVR agreement specifies that, without limitation, in no event shall declining to effect a licensing agreement and/or sale agreement and/or similar transfer agreement and/or agreement for the grant of an option to enter into any such transaction on terms and conditions that create a commercially unreasonable risk of liability on the part of Ligand or the surviving corporation be deemed not to satisfy the “in good faith and with commercial reasonableness” standard. Moreover, in no event shall declining to effect a sale or transfer of the Roche Agreement rights (including royalty rights, milestone payment rights or rights to all or any portion of a drug candidate or technology licensed pursuant to the Roche Agreement) or any other decision to retain existing rights under the Roche Agreement be deemed not to satisfy the “in good faith and with commercial reasonableness” standard under the Roche CVR agreement.

Achievement and Non-Achievement Certificates

The CVR agreements provide for Ligand to deliver achievement or non-achievement certificates (reflecting, respectively, satisfaction or non-satisfaction of the conditions to payment described above), as applicable, to the rights agent and Stockholders’ Representative. Upon receipt of a non-achievement certificate, the Stockholders’ Representative may, but only within 45 days of receipt of the non-achievement certificate and only if he has first obtained the assent of the holders of 20% of the outstanding CVRs under the applicable CVR agreement, deliver a notice specifying that the Stockholders’ Representative objects to the non-achievement certificate. Such notice shall include a statement of the reason upon which the Stockholders’ Representative has determined that the condition to payment was satisfied within the required time period.

If Ligand does not agree with any or all of the objections to the non-achievement certificate as stated in such notice, Ligand and the Stockholders’ Representative shall negotiate in good faith for a period of 30 days to resolve the dispute. After expiration of the 30-day period, any remaining objections will be settled by binding arbitration pursuant to the terms of the General CVR agreement.

If Ligand delivers to the rights agent an achievement certificate (or if the CVR payment amount is otherwise determined to be payable pursuant to the arbitration provisions in the CVR agreement), Ligand shall establish a CVR payment date that is the January 1 st or July 1st which next follows the date of the achievement certificate (or the date of final determination pursuant to the arbitration provisions in the applicable CVR agreement). At least five business days before such CVR payment date, Ligand shall cause the CVR payment amount to be delivered to the rights agent, who will in turn, on such CVR payment date, distribute the CVR payment amount on a pro rata basis to the applicable CVR holders.

Rights of CVR Holders

The rights of a CVR holder are limited to those expressed in the applicable CVR agreement. The CVRs will not entitle the holders thereof, by virtue of their ownership of CVRs, to any of the rights of a Ligand stockholder. The CVR agreements will be governed by California law.

Stockholders’ Representative as Sole Actor

To the extent permitted by applicable law, in no event shall any holders of CVRs (as opposed to the Stockholders’ Representative) or any former stockholders of Metabasis (as opposed to the Stockholders’ Representative) have, after the effective time of the merger, any power or right to commence or join in any claim (presented formally to a judicial or quasi-judicial governmental entity), lawsuit, court action, suit, arbitration or other judicial or administrative proceeding based on or arising out of any CVR agreement or the merger agreement.

Amendment of CVR Agreements

Ligand may, with the written consent of the Stockholders’ Representative and the holders of at least 20% of the applicable series of CVRs, enter into one or more amendments to any CVR agreement for the purpose of

 

99


Table of Contents

adding, eliminating or changing any provision of the applicable CVR agreement, even if the addition, elimination or change is in any way adverse to the rights of CVR holders and/or to the interests of the Stockholders’ Representative. Any such amendment shall be fully valid even if such amendment is signed only by Ligand and the rights agent.

Ligand, at any time and from time to time, may without the consent of the Stockholders’ Representative, the CVR holders or the rights agent, enter into one or more amendments to the CVR agreements, for any of the following purposes:

 

   

to evidence the succession of another person to Ligand and the assumption by any successor of the covenants of Ligand in the applicable CVR agreement; or

 

   

to evidence the termination of the applicable CVR registrar and the succession of another person as a successor CVR registrar and the assumption by any successor of the obligations of the CVR registrar.

Ligand and the rights agent, at any time and from time to time, may without the consent of the Stockholders’ Representative or the CVR holders, enter into one or more amendments to the CVR agreements, for any of the following purposes:

 

   

to evidence the succession of another person as a successor rights agent and the assumption by any successor of the covenants and obligations of the rights agent;

 

   

to add to the covenants of Ligand any further covenants, restrictions, conditions or provisions as Ligand and the board of directors considered to be for the protection of CVR holders; provided that in each case, the provisions do not adversely affect the rights of CVR holders;

 

   

to cure any ambiguity, to correct or supplement any provision in the applicable CVR agreement that may be defective or inconsistent with any other provision, or to make any other provisions with respect to matters or questions arising under the applicable CVR agreement; provided that in each case, the provisions do not adversely affect the rights of CVR holders; or

 

   

to add, eliminate or change any provision in the applicable CVR agreement unless such addition, elimination or change is adverse to the rights of CVR holders and/or the interests of the Stockholders’ Representative.

Consolidation, Merger, Sale or Conveyance of Ligand

Under the terms of the CVR agreements, Ligand may not consolidate with or merge into any other person or convey, transfer or lease its properties and assets substantially as an entirety to any person, unless (i) such person expressly assumes payment of amounts on all the CVRs and the performance of every duty and covenant of the CVR agreements on the part of Ligand to be performed or observed and (ii) Ligand has delivered to the rights agent a certificate of one of its officers, stating that such consolidation, merger, conveyance, transfer or lease complies with the CVR agreements and that all conditions provided for relating to such transaction have been complied with. The CVR agreements expressly provide that such a consolidation, merger, or conveyance/transfer/sale substantially as an entirety shall not be deemed a sale transaction for any Program for the purpose of triggering or sizing a payment under any of the CVR agreements.

Termination of CVR Agreements

Each of the TR Beta CVR, Glucagon CVR and General CVR agreements generally terminate upon the first day after the later to occur of the tenth anniversary of the CVR agreement or the date that the payment of the last possible CVR payment under such CVR could occur (arising from events that occur before the tenth anniversary of the CVR agreement), and on which no further dispute is possible. The Roche CVR terminates upon the first day after the date that the payment of the last possible CVR payment under the Roche CVR could occur, and on which no further dispute is possible.

Voting Agreements

As an inducement to Ligand and as a condition to Ligand’s entering into the merger agreement, each of MPM Asset Management Investors 2000 B LLC, MPM BioVentures II, L.P., MPM BioVentures II-QP, L.P., MPM BioVentures GMBH&Co Parallel- Beteiligungs KG, InterWest Partners VII, L.P., InterWest Investors VII, L.P. and all the directors and officers of Metabasis as of October 26, 2009, or collectively the stockholder parties, entered into voting agreements with Ligand, whereby the stockholder parties agreed to vote all of the shares of Metabasis common stock beneficially owned by them in favor of adoption of the merger agreement and approval of the merger and against any acquisition proposal or superior proposal. The stockholder parties also granted Ligand an irrevocable proxy to vote such shares in accordance with the preceding sentence. The voting agreements limit the ability of the stockholder parties to sell or otherwise transfer the shares of Metabasis common stock beneficially owned by them. As of October 26, 2009, the stockholder parties owned an aggregate of approximately 28.9% of the outstanding shares of Metabasis common stock. The voting agreements will terminate upon (i) mutual agreement, (ii) the effective time of the merger, (iii) the termination of the merger agreement in accordance with its terms or (iv) any amendment, modification or change (or waiver, which waiver is made at the request of, or with the consent of, Ligand) to the terms of the merger agreement or one or more of the CVR agreements that is not consented to by a stockholder party and is or results in (x) any change (adverse-to-the-stockholder-party) to the economic terms of the CVRs and the forms of CVR agreements, or (y) any change to the merger agreement provisions governing the economic terms of any potential cash payment that may be paid to Metabasis’ stockholders, or (z) any change in the form of consideration payable pursuant to the merger agreement or the CVR agreements.

Table of Contents

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS OF METABASIS

The following table provides information regarding the beneficial ownership of Metabasis’ common stock as of October 23, 2009 by: (i) each of Metabasis’ directors, (ii) each of Metabasis’ 2008 named executive officers, (iii) all of Metabasis’ current directors and executive officers as a group, and (iv) each person, or group of affiliated persons, known by Metabasis to beneficially own more than 5% of Metabasis’ common stock. The table is based upon information supplied by Metabasis’ officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed with the SEC. Unless otherwise indicated in the footnotes to the table and subject to community property laws where applicable, Metabasis believes that each of the stockholders named in the table has sole voting and investment power with respect to the shares indicated as beneficially owned.

Applicable percentages are based on 35,157,359 shares outstanding on October 23, 2009, adjusted as required by rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options or warrants that are exercisable on or within 60 days after October 23, 2009. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Notwithstanding the foregoing, the information provided as to Wellington Management Company, LLP in the table and footnote 7 thereto has been updated to reflect information contained in the Schedule 13G filed by Wellington Management Company, LLP with the SEC on November 10, 2009.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined balance sheet is based on historical unaudited balance sheets of Ligand and Metabasis and has been prepared to reflect the merger as if it had been completed on the balance sheet date of September 30, 2009. The following unaudited pro forma condensed combined statements of operations give effect to the merger as if it had taken place on January 1, 2008, the beginning of the earliest period presented, in accordance with SEC guidance.

The merger will be accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations, as amended. Under the purchase method of accounting, the total estimated purchase price, calculated as described in Note 2 to these unaudited pro forma condensed combined financial statements, is allocated to the net tangible and intangible assets of Metabasis based on their estimated fair values. Management has made a preliminary allocation of the estimated purchase price to the tangible and intangible assets acquired and liabilities assumed based on various preliminary estimates. A final determination of these estimated fair values, which cannot be made prior to the completion of the merger, will be based on the actual net tangible and intangible assets of Metabasis that exist as of the date of completion of the merger, and upon the final purchase price. Differences between the preliminary and final purchase price allocations could have a material impact on the unaudited pro forma condensed combined financial information and Ligand’s future results of operations and financial position.

The unaudited pro forma condensed combined financial information is based on the estimates and assumptions which are preliminary and have been made solely for purposes of developing such pro forma information. They do not include liabilities that may result from integration activities which are not presently estimable. The management of Ligand and Metabasis are in the process of making these assessments, and estimates of these costs are not currently known. The unaudited pro forma condensed combined financial statements are not necessarily an indication of the results that would have been achieved had the merger been completed as of the dates indicated or that may be achieved in the future.

Under the terms of the Merger Agreement, each share of Metabasis common stock will be converted into the right to receive a pro rata portion of a total cash payment equal to $3,207,500 less Metabasis’ estimated net liabilities (as defined in the merger agreement) at closing and also less $150,000 to be deposited in the Stockholders’ Representative’s fund. In addition, each Metabasis stockholder will receive, for each share of Metabasis stock held, (i) one Roche CVR, (ii) one TR Beta CVR, (iii) one Glucagon CVR and (iv) one General CVR. At the closing of the merger, Ligand, Metabasis, the Stockholders’ Representative and a rights agent will also enter into four contingent value rights agreements, or CVR agreements, in the forms attached to this proxy statement/prospectus as Annex B, Annex C, Annex D and Annex E. The CVR agreements set forth the rights that former Metabasis stockholders will have with respect to each CVR to be held by them after the closing of the merger. Each Metabasis stockholder will receive one CVR under each of the four CVR agreements for each share of Metabasis stock held. The CVRs will not be listed on any securities exchange but will be generally tradable, subject to certain procedures.

This unaudited pro forma condensed combined financial information should be read in conjunction with the historical consolidated financial statements and notes thereto of Ligand and Metabasis and other financial information pertaining to Ligand and Metabasis, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” incorporated by reference or included herein.

On October 26, 2009, Ligand and Merger Sub entered into a merger agreement with Metabasis, which was amended on November 25, 2009. Upon completion of the merger, if the merger agreement is adopted by Metabasis’ stockholders and the other conditions to the merger are satisfied or waived, each share of Metabasis common stock will be converted into the right to receive a pro rata portion of a total cash payment equal to $3,207,500 less Metabasis’ estimated net liabilities (as defined in the merger agreement) at closing and also less $150,000 to be deposited in the Stockholders’ Representative’s fund. In addition, each Metabasis stockholder will receive, for each share of Metabasis stock held, (i) one Roche CVR, (ii) one TR Beta CVR, (iii) one Glucagon CVR and (iv) one General CVR.

At the closing of the merger, Ligand, Metabasis, the Stockholders’ Representative and a rights agent will also enter into four contingent value rights agreements, or CVR agreements, in the forms attached to this proxy statement/prospectus as Annex B, Annex C, Annex D and Annex E. The CVR agreements set forth the rights that former Metabasis stockholders will have with respect to each CVR to be held by them after the closing of the merger. Each Metabasis stockholder will receive one CVR under each of the four CVR agreements for each share of Metabasis stock held. The CVRs will not be listed on any securities exchange but will be generally tradable, subject to certain procedures.

Subject to certain adjustments (including the required payments of certain contingent liabilities and contributions to the Stockholders’ Representative fund), holders of the Roche CVRs will receive (if and when payable on the January 1st or July 1st following the triggering payment event), the following payouts: (i) 65% of any milestone payments received by Ligand or Metabasis after October 1, 2009 under a collaboration and license agreement with Hoffmann-La Roche Inc. and its affiliates (the “Roche Agreement”); (ii) 68% of any royalty payments received by Ligand or Metabasis after October 1, 2009 under the Roche Agreement; (iii) 65% of any aggregate proceeds (less reasonable out of pocket transactional expenses and costs incurred by Ligand or Metabasis after October 1, 2009) received by Ligand or Metabasis after October 1, 2009 in connection with a sale or transfer of the Roche Agreement rights (including royalty rights, milestone payment rights or rights to all or any portion of a drug candidate or technology licensed pursuant to the Roche Agreement); and (iv) a proportionate share of any amounts finally distributed to the holders of CVRs from the Stockholders’ Representative fund.

TR Beta CVR. Subject to certain adjustments (including the required payments of certain contingent liabilities and contributions to the Stockholders’ Representative fund), holders of the TR Beta CVRs will receive (if and when payable on the January 1st or July 1st following the triggering payment event), the following payouts: (i) (a) 50% of any aggregate proceeds (less reasonable out of pocket transactional expenses and costs incurred by Ligand) received by Ligand in connection with transactions, including licensing or sale transactions, with respect to the TR Beta Program (as defined in the TR Beta CVR agreement) before the sixth anniversary of the merger, (b) 40% of any aggregate proceeds (less reasonable out of pocket transactional expenses and costs incurred by Ligand) received by Ligand in connection with transactions, including licensing or sale transactions, with respect to the TR Beta Program after the sixth anniversary of the merger and before the seventh anniversary of the merger, (c) 30% of any aggregate proceeds (less reasonable out of pocket transactional expenses and costs incurred by Ligand) received by Ligand in connection with transactions, including licensing or sale transactions, with respect to the TR Beta Program after the seventh anniversary of the merger and before the eighth anniversary of the merger, or (d) 20% of any aggregate proceeds (less reasonable out of pocket transactional expenses and costs incurred by Ligand) received by Ligand in connection with transactions, including licensing or sale transactions, with respect to the TR Beta Program after the eighth anniversary of the merger and before the tenth anniversary of the merger; and (ii) a proportionate share of any amounts finally distributed to the holders of CVRs from the Stockholders’ Representative fund.

of any rights to receive such milestone payments or royalty payments or all or any portion of a drug candidate or technology from the drug development program licensed pursuant to certain PeriCor Agreements; (v) 100% of the cash received by Ligand upon a cash exercise of any of the Metabasis warrants outstanding as of the date of the merger; (vi) 50% of the aggregate proceeds (less reasonable out of pocket transactional expenses and costs incurred by Ligand) received by Ligand in connection with any sale of Metabasis’ QM/MM Technology (as defined in the General CVR agreement); and (vii) a proportionate share of any amounts finally distributed to the holders of CVRs from the Stockholders’ Representative fund.

(2) Purchase Price

Total estimated purchase price is summarized as follows (in thousands):

 

Estimated cash payment to Metabasis stockholders

   $ 1,818

Estimated fair value of Contingent Value Rights

     14,573
      

Total preliminary estimated purchase price

   $ 16,391
      

For purposes of the preliminary purchase price allocation, the estimated fair value of the Roche, TR Beta, Glucagon and General Contingent Value Rights is based upon the total estimated fair value of Metabasis of approximately $30 million, which is consistent with Metabasis’ market value as of October 26, 2009 (the last full trading day before the public announcement of the merger agreement). For purposes of estimating the preliminary purchase price, Ligand’s management assumed that an aggregate of 50% of the total identifiable intangible assets’ estimated fair value would be paid out to Metabasis stockholders under the provisions of the Contingent Value Rights agreements. As of November 23, 2009, the market value of the Metabasis common stock had decreased significantly to approximately $13 million. The decrease could indicate a significantly lower value of the identifiable intangible assets and a corresponding reduction in purchase price. For example, based on assumptions used by Ligand’s management, the preliminary estimated purchase price on November 23, 2009 would have been $7.1 million, resulting in estimated fair value of the identifiable intangible assets of $9.5 million, Contingent Value Rights of $5.3 million and gain on acquisition of $5.3 million.

For purposes of this pro forma analysis, the above estimated purchase price has been allocated based on a preliminary estimate of the fair value of assets acquired and liabilities assumed:

 

     (in thousands)

Assets Acquired:

  

Cash & cash equivalents

   $ 2,215

Assets held for sale

     867

Other assets

     1,002

Goodwill and other identifiable intangible assets

     28,120
      

Total Assets

     32,204

Liabilities Assumed:

     1,205

Payable to Metabasis stockholders

     14,573

     35
      

Total Liabilities

(3) Pro Forma Adjustments

Adjustments included in the column under the heading “Pro Forma Adjustments” are related to the following (in thousands, except share information):

 

  (a) Cash and cash equivalents adjustments consist of the following:

 

Estimated cash payment to Metabasis stockholders

   $ (1,818

Estimated Ligand transaction fees

     (400

Estimated Metabasis transaction fees

     (1,200
        

Total

   $ (3,418
        

 

  (b) To record the estimated fair value of goodwill and other identifiable intangible assets, which is primarily related to Metabasis’ internal and partnered early stage product candidates. For purposes of the preliminary purchase price allocation, goodwill and other identifiable intangible assets are combined for this presentation which includes the estimated fair value of the related liability for the CVR agreements and resulting gain on acquisition. No amortizable intangible assets have been identified in the preliminary analysis. For purposes of estimating the preliminary purchase price, Ligand’s management assumed that an aggregate of 50% of the total identifiable intangible assets’ estimated fair value would be paid out to Metabasis stockholders under the provisions of the Contingent Value Rights agreements based on various percentage payouts included in the individual Contingent Value Rights agreements. An increase in the estimated aggregate percentage paid to Metabasis stockholders would result in an increase to the estimated liability for the CVR agreements and a decrease to the gain on acquisition. A decrease in the estimated aggregate percentage paid to Metabasis stockholders would result in a decrease to the estimated liability for the CVR agreements and an increase to the gain on acquisition. The final valuation will be performed as of the date of completion of the merger. Differences between the preliminary and final valuation could have a material impact on the accompanying unaudited pro forma condensed combined financial statement information and Ligand’s future results of operations and financial position.

 

  (c) To record the following adjustments to common stock:

 

Elimination of Metabasis common stock

   $ (35
        

 

  (d) To record the following adjustments to additional paid-in capital:

 

Elimination of Metabasis paid-in capital

   $ (197,654
        

 

  (e) To record the following adjustments to accumulated deficit:

 

Elimination of Metabasis accumulated deficit

   $ 194,845   

Adjustment for transaction related fees

     (1,600

Gain on acquisition (see note g)

     14,573   
        

Total

   $ 207,818   
        

 

  (f) To eliminate interest income foregone on net cash and cash equivalents used to pay transaction related costs.

approximately $13 million. The decrease could indicate a significantly lower value of the identifiable intangible assets and a corresponding reduction in the purchase price.

 

  (h) For purposes of these unaudited pro forma condensed combined financial statements, the unaudited pro forma combined basis and diluted net income per share amounts are based on the historical weighted average number of shares of Ligand common stock outstanding:

For the nine months ended September 30, 2009:

Section 2.10        Dissenting Shares

Notwithstanding anything in this Agreement to the contrary, any Company Share issued and outstanding immediately before the Effective Time held by a holder who is entitled to demand and properly demands appraisal of such Company Shares (the “Dissenting Shares”), pursuant to, and who complies in all respects with, Section 262 of the DGCL (the “Appraisal Rights”), shall not be converted into the right to receive the Merger Consideration, but instead shall be converted into the right to receive such consideration as may be due such holder pursuant to Section 262 of the DGCL unless such holder fails to perfect, withdraws or otherwise loses such holder’s right to such payment or appraisal. From and after the Effective Time, a holder of Dissenting Shares shall not have and shall not be entitled to exercise any of the voting rights or other rights of a stockholder of the Company or the Surviving Corporation. If, after the Effective Time, such holder fails to perfect, withdraws or otherwise loses any such Appraisal Rights, each such share of such holder shall no longer be considered a Dissenting Share and shall be deemed to have converted as of the Effective Time into the right to receive the Merger Consideration in accordance with Section 2.06(iii). The Company shall give prompt notice to Parent of any demands received by the Company for appraisal of Company Shares, withdrawals of such demands and any other instruments served pursuant to the DGCL received by the Company, and Parent shall have the right to control all negotiations and proceedings with respect to such demands. Before the Effective Time, the Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to, or settle or offer to settle, any such demands or agree to do or commit to do any of the foregoing.

(ii) Any such termination of employment shall be treated as a “termination without cause” or “benefits eligible termination” (or equivalent term) by the Company entitling such employees to full severance payments and benefits under the employment agreements listed on Section 5.09 of the Company Disclosure Letter, determined on the basis that such termination has occurred in connection with a change in control, as applicable to individual employees. Section 5.09 of the Company Disclosure Letter sets forth the amounts of the cash severance payments applicable as of the Effective Time to each employee covered by an employment agreement with the Company. Before the Effective Time, the Company Board may in its sole discretion deliver letters to individual employees setting forth their severance payments and benefits upon termination of employment, on a basis consistent with this Section 5.09. Notwithstanding anything contained herein to the contrary, in no event shall any officer’s voluntary resignation (as contemplated by this Agreement) affect such Person’s eligibility to receive the severance payments set forth on Section 5.09 of the Company Disclosure Letter or otherwise alter the classification of the termination of employment as contemplated under this Section 5.09.

(iii) From and after the Effective Time, Parent shall, or shall cause a Parent Subsidiary, the Surviving Corporation or a Subsidiary of the Surviving Corporation, to honor the terms of the employment agreements listed on Section 5.09 of the Company Disclosure Letter, including, without limitation, the payment of continuing severance payments for the period set forth in such employment agreements. The severance amounts payable under such employment agreements to any Company employee who continues in the employ of the Surviving Corporation shall be paid to such employee by the Surviving Corporation or Parent on the first Business Day after such employee’s employment with the Surviving Corporation/Parent terminates or as otherwise required or provided for by the Contracts governing the severance payments.

(b) 401(k) Plan.

(i) If so requested by Parent in writing, the Company shall before the Effective Time amend the Company’s 401(k) plan to require, in the event of plan termination, in-kind distribution of any CVRs in a participant’s account, and take all customary ancillary actions in connection with such amendment.

(ii) If so requested by Parent in writing, and whether or not such amendment shall have been requested, the Company shall as of immediately before the Effective Time terminate the Company’s 401(k) plan and take all customary ancillary actions in connection with such termination.

(c) Health Care. From and after the Effective Time, Parent shall, or shall cause a Parent Subsidiary, the Surviving Corporation or a Subsidiary of the Surviving Corporation, to (i) at a minimum, honor in accordance with their terms the obligations of the Company to provide continued medical and dental coverage to employees and their eligible family members under the terms of the employment agreements listed on Section 5.09 of the Company Disclosure Letter, with the understanding that the Company’s health plans will be terminated and coverage will instead be provided through Parent’s health plans, and (ii) as and to the extent required by applicable Legal Requirements, continue to provide “COBRA” continuation coverage to former employees of the Company, with the understanding that the Company’s health plans will be terminated and coverage will instead be provided through Parent’s health plans.

(d) This Section 5.9 shall survive the Effective Time and the consummation of the Merger. This Section 5.9 is intended to benefit, and may be enforced by, the employees or former employees entitled to the rights set forth hereunder and their respective heirs, representatives, successors and assigns, and shall be binding on all successors and assigns of Parent and the Surviving Corporation.

A-36


Table of Contents

provision in favor of an Indemnified Party that is set forth in the certificate of incorporation or bylaws of the Company and the equivalent organizational documents of any Company Subsidiary in effect as of the date of this Agreement and (iii) any other rights to indemnification now existing in favor of any Indemnified Party under any statute or any express written Contract. The certificate of incorporation and bylaws of the Surviving Corporation shall contain the provisions with respect to indemnification and exculpation from liability set forth in the Company’s certificate of incorporation and bylaws on the date of this Agreement, and, from and after the Effective Time, such provisions shall not be amended, repealed or otherwise modified in any manner that could adversely affect the rights thereunder of any Indemnified Party.

(b) Without limiting the provisions of Section 5.10(a), during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, Parent shall indemnify and hold harmless each Indemnified Leader against and from any costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any Legal Proceeding, arbitration, investigation or inquiry, whether civil, criminal, administrative or investigative, to the extent such Legal Proceeding, arbitration, investigation or inquiry arises directly or indirectly out of or pertains directly or indirectly to: (i) any action or omission or alleged action or omission in such Indemnified Leader’s capacity as a director, officer, employee or agent of the Company or any Company Subsidiary or other Affiliates (regardless of whether such action or omission, or alleged action or omission, occurred before, at or after the Effective Time); or (ii) any of the transactions contemplated by this Agreement; provided, however, that if, at any time before the sixth anniversary of the Effective Time, any Indemnified Leader delivers to the Company, the Surviving Corporation or Parent, as applicable, a written notice asserting a claim for indemnification under this Section 5.10(b), then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In the event of any such Legal Proceeding, arbitration, investigation or inquiry: (A) any counsel retained by the Indemnified Leaders with respect to the defense thereof for any period after the Effective Time must be reasonably satisfactory to Parent; and (B) Parent will pay the reasonable fees and expenses of such counsel, promptly after statements therefor are received; provided that the individual to whom expenses are advanced provides an undertaking to repay such advances to the extent required by applicable Legal Requirements. The Indemnified Leaders as a group may retain only one law firm (in addition to local counsel) to represent them with respect to any single action unless counsel for any Indemnified Leader determines in good faith that, under applicable standards of professional conduct, a conflict exists or is reasonably likely to arise on any material issue between the positions of any two or more Indemnified Leaders. Notwithstanding anything to the contrary contained in this Section 5.10(b) or elsewhere in this Agreement, Parent agrees that it will not settle or compromise or consent to the entry of any judgment or otherwise seek termination with respect to any Legal Proceeding, arbitration, investigation or inquiry for which indemnification may be sought under this Agreement unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnified Leaders from all liability arising out of such Legal Proceeding, arbitration, investigation or inquiry.

(c) Through the sixth anniversary of the Effective Time, Parent will cause the Surviving Corporation to maintain in effect, for the benefit of the Company’s directors and officers that are insured under the Company’s current directors’ and officers’ liability insurance policy in effect as of the date of this Agreement (the “D&O Insurance Policy”), the current level and similar scope of directors’ and officers’ liability insurance coverage as set forth in the D&O Insurance Policy with a carrier selected by Parent; provided, however, that in no event shall the Surviving Corporation be required pursuant to this Section 5.10(c) to expend in any one year an amount in excess of $60,000, it being understood that if the annual premiums payable for such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a policy with what Parent determines in good faith to be the most favorable coverage available for a cost equal to such amount. At any time before the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company may purchase a customary “tail” prepaid policy on the D&O Insurance Policy covering a period of six years from the Effective Time for a total premium of no more than $360,000. In the event that the Company shall purchase such a customary “tail” prepaid policy before the Effective Time, Parent will cause the Surviving Corporation to maintain such “tail” policy in full force and effect and continue to honor its respective obligations thereunder, in

lieu of all other obligations of Parent under the first sentence of this Section 5.10(c), for so long as such “tail” policy shall be maintained in full force and effect.

(d) Parent and the Surviving Corporation jointly and severally agree to pay all expenses, including attorneys’ fees, that may be incurred by the Indemnified Parties in successfully enforcing their indemnity rights and other rights provided in this Section 5.10.

(e) This Section 5.10 shall survive the Effective Time and the consummation of the Merger. This Section 5.10 is intended to benefit, and may be enforced by, the Indemnified Parties and their respective heirs, representatives, successors and assigns, and shall be binding on all successors and assigns of Parent and the Surviving Corporation.

Section 5.11        Section 16 Matters.

Before the Effective Time, Parent and the Company shall take all such steps as may be required to cause any dispositions of Company Shares (including derivative securities with respect to Company Shares) resulting from the Merger by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act, including, without limitation, actions in accordance with that certain No-Action Letter dated January 12, 1999 issued by the SEC regarding such matters.

Section 5.12        Plan of Reorganization.

The parties agree that the Merger shall not be, and they shall not report the Merger as, a tax-free reorganization within the meaning of Section 368 of the Code.

Section 5.13        Consultants.

(a) From and after the date hereof, Parent shall use commercially reasonable efforts to negotiate and agree to terms with as many of the individuals listed on Exhibit E attached hereto as possible (referred to herein as the “Consulting Committee”), to assist, in the role of consultants, and with such consulting to begin as of the Effective Time, in Parent’s efforts toward selling or licensing the ‘7133 Program by the sixth-month anniversary of the Effective Time; provided, that Parent shall not be required to provide more than $40,000 in the aggregate for the compensation of the Consulting Committee.

(b) It is understood that, from and after the Effective Time, Parent’s Board of Directors and management shall have the ultimate authority to lead, direct and approve the sale/license process described in paragraph (a) of this Section 5.13 and to determine (subject to the obligation to act in good faith and with commercial reasonableness) whether or not to seek, solicit, negotiate or accept any proposed offer to sell or license the ‘7133 Program or any other Program by any deadline (or ever or at all), and that Parent shall have no liability for decisions, actions and inactions in this regard that are taken in good faith and with commercial reasonableness; provided, that notwithstanding the foregoing, until the sixth-month anniversary of the Effective Time, Parent shall use commercially reasonable efforts to cause its management to implement any particular proposed sale or license of the ‘7133 Program recommended by the Consulting Committee on terms and conditions that do not create a commercially unreasonable risk of liability to Parent.

Section 5.14        Efforts to Satisfy Closing Conditions.

Each of Parent, Merger Sub and the Company shall use its reasonable best efforts to cause the conditions to the other party’s obligations to effect the Merger and the other Transactions to be satisfied. Each party hereto, at the reasonable request of the other, shall execute and deliver such other instruments and do and perform such other acts and things as may be reasonably necessary and consistent with this Agreement to effect the consummation of the Merger and other Transactions contemplated by this Agreement.

(e) All Funding by Parent shall be done in good faith and with commercial reasonableness; provided, that upon Parent incurring an aggregate of $8,000,000 in Funding, no additional Funding shall be subject to such standard.

Section 7.03        Termination Fee.

(a) If: (i) this Agreement is validly terminated by either Parent or the Company pursuant to Section 7.01(b) or Section 7.01(c); (ii) neither Parent not Merger Sub shall have materially breached any of its representations, warranties or covenants contained in this Agreement; and (iii) at or before the time of any such termination of this Agreement an Acquisition Proposal shall have been made (and such Acquisition Proposal shall not have been withdrawn before the time of the termination of this Agreement) and within 12 months after the date of termination of this Agreement, the Company or any Company Subsidiary consummates an Acquisition Transaction (replacing for purposes of this Section 7.03(a), “20%” in the definition thereof with “50%”) or enters into a Contract to consummate an Acquisition Transaction that is subsequently consummated, then, within two Business Days after such Acquisition Transaction is consummated the Company shall pay the Termination Fee to Parent.

(b) If this Agreement is validly terminated by Parent pursuant to Section 7.01(e) or Section 7.01(g), then, within two Business Days after such termination, the Company shall pay the Termination Fee to Parent.

(c) If this Agreement is validly terminated by the Company pursuant to Section 7.01(f), before (or contemporaneously with) and as a condition to the effectiveness of such termination, the Company shall pay the Termination Fee to Parent.

(d) Each of the parties hereto acknowledges that the agreements contained in this Section 7.03 are an integral part of the transactions contemplated by this Agreement and that the Termination Fee is not a penalty, but rather is liquidated damages in a reasonable amount that will compensate Parent and Merger Sub, as the case may be, in the circumstances in which such Termination Fee is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions, which amount would otherwise be impossible to calculate with precision.

(e) In circumstances under which the Termination Fee is payable and has been paid, Parent and Merger Sub agree that (i) to the extent they have incurred losses or damages in connection with this Agreement other than as a result of fraud or intentional misconduct, their sole and exclusive remedy against the Company and any of its directors, officers, Affiliates or Representatives for any breach, loss or damage shall be to receive payment of the Termination Fee to the extent provided in Section 7.03 and (ii) upon payment in full of such amounts, (x) neither Parent nor Merger Sub shall have any other rights or claims or seek damages against the Company or any of its directors, officers, Affiliates or Representatives under this Agreement or otherwise, whether at law or equity, in contract, in tort or otherwise, and (y) neither the Company nor any of its directors, officers, Affiliates or Representatives shall have any further liability or obligations relating to or arising out of this Agreement or the Transactions.

All transfer, documentary, sales, use, stamp, registration and other substantially similar Taxes and fees (including any penalties and interest) incurred in connection with this Agreement (collectively, “Transfer Taxes”) shall be paid by Parent and Merger Sub when due, and Parent and Merger Sub will, at their own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes.

Section 8.08        Assignability; No Third Party Rights.

Before the Effective Time, neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of a Legal Requirement or otherwise, by any of the parties without the prior written consent of the other parties and any purported assignment without such consent shall be void. This Agreement shall be binding upon, and shall be enforceable by and inure to the benefit of, the parties hereto and their respective permitted successors and assigns. Notwithstanding anything contained herein to the contrary, Parent shall not consolidate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, unless the Person formed by such consolidation or into which Purchaser is merged or the Person that acquires by conveyance or transfer, or that leases, the properties and assets of Purchaser substantially as an entirety shall expressly assume (or assumes by operation of law) (a) payment (if and to the extent required) of all amounts that may become payable under the CVR Agreements and (b) the performance of every duty and covenant of the CVR Agreements on the part of Parent to be performed or observed; provided, further, Parent shall remain jointly and severally liable for the foregoing obligations after the date of such transfer, lease or similar transaction. Except (i) for the rights of stockholders and holders of other securities to receive payment in accordance with Article II after the Effective Time, (ii) as set forth in Section 5.09 and Section 5.10 and (iii) for the right of the Company (but not of the Surviving Corporation), on behalf of its stockholders, to pursue damages in the event of Parent’s or Merger Sub’s breach of this Agreement, nothing in this Agreement, express or implied, is intended to or shall confer upon any Person, other than the parties hereto, any right, benefit or remedy of any nature. In circumstances in which the stockholders of the Company do not have the right to seek remedies at law or equity, the obligations of Parent and Merger Sub under this Agreement are material to the Company’s execution of this Agreement and any failure by Parent or Merger Sub to comply with the terms of this Agreement shall enable the Company (but not the Surviving Corporation) to seek all remedies available at law or equity to it and on behalf of the stockholders.

In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to negotiate in good faith to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

Section 8.13        Remedies.

The Rights Agent is hereby initially appointed Roche CVR registrar and transfer agent (“Roche CVR Registrar”) for the purpose of registering Roche CVRs and transfers of Roche CVRs as herein provided. Upon any change in the identity of the Rights Agent, the successor Rights Agent shall automatically also become the successor Roche CVR Registrar.

(c) Every request made to transfer a Roche CVR must be in writing and accompanied by a written instrument or instruments of transfer and any other documentation requested by Buyer or Roche CVR Registrar, in a form reasonably satisfactory to Buyer and the Roche CVR Registrar, properly completed and duly executed by the registered Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, such signature to be guaranteed by a participant in a recognized Signature Guarantee Medallion Program. Upon receipt of such written request and materials, and all other reasonably necessary information, the Roche CVR Registrar shall register the transfer of the Roche CVRs in the Roche CVR Register. All duly transferred Roche CVRs registered in the Roche CVR Register shall be the valid obligations of Buyer, evidencing the same right and shall entitle the transferee to the same benefits and rights under this Agreement, as those previously held by the transferor. No transfer of a Roche CVR shall be valid until registered in the Roche CVR Register, and any transfer not duly registered in the Roche CVR Register will not be honored by Buyer or the Rights Agent until it is so registered, and then it will be honored only prospectively. Any transfer or assignment of the Roche CVRs shall be without charge (other than the cost of any tax or charge that may be payable in respect of such transfer or assignment, which shall be the responsibility of the transferor) to the Holder. The Rights Agent shall have no duty or obligation under any Section of this Agreement that requires the payment of taxes or charges unless and until it is satisfied that such taxes and/or charges have been or will be paid.

(d) A Holder may make a written request to the Roche CVR Registrar to change such Holder’s address of record in the Roche CVR Register.

Until such Achievement Certificate is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that a Roche CVR Payment Event has not occurred. No transaction described in Section 6.1(a) hereof shall give the Holders the right to receive a Roche CVR Payment Amount. Such cash amount deposited with the Rights Agent shall, pending its disbursement to such holders, be invested by the Rights Agent in (i) direct obligations of the United States of America, (ii) obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, or (iii) money market funds investing solely in a combination of the foregoing. Any interest and other income resulting from such investments shall be applied first to the satisfaction of the Rights Agent Fees and Expenses, and any remainder (the “Remainder”) shall be paid to the Holders as set forth in Section 2.4(e) below. The Rights Agent must receive federal or other immediately available funds before 1:00 p.m., Eastern Time, on the funding date in order for such funds to be so invested on such date.

Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that the Roche CVR Payment Date has not occurred. The Rights Agent shall have no duty or obligation to establish any payment amount or payment date with respect to the Roche CVR Payment Date. Upon receipt of such written notice and all other necessary information, the Rights Agent will, on such Roche CVR Payment Date, distribute the Roche CVR Payment Amount and the Remainder to the Holders (each Holder being entitled to receive its pro rata share of the Roche CVR Payment Amount and the Remainder based on the number of Roche CVRs held (as of the third Business Day before the Roche CVR Payment Date) by such Holder as reflected on the Roche CVR Register) by check mailed to the address of each such respective Holder as then reflected in the Roche CVR Register.

To the extent that amounts are so withheld or paid over to or deposited with the relevant governmental entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made.

(a) It is understood that upon the occurrence of certain payment events under this Agreement and the other CVR Agreements, the Landlord may be entitled to payments pursuant to the terms of Section 10 of the Landlord Agreement and the employees that were terminated in Target’s May 2009 reduction in force may be entitled to contingent severance payments pursuant to their respective severance arrangements (together, and including any payments to resolve claims arising in connection therewith, the “Contingent Payments”).

(b) In general, such Contingent Payments are to be satisfied first from amounts otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event, but in some instances the full amount payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event will be less than the Contingent Payments owing in respect of such payment event.

(d) If an Excess is paid by Buyer pursuant to Section 2.7(c) of this Agreement or of any of the other CVR Agreements, then upon the next payment event under this Agreement or under any of the other CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid), Buyer shall withhold from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event, and shall keep for Buyer’s own account to reimburse Buyer for having paid the Excess, an amount equal to 100% of the Excess (or, if less, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event). If Buyer is not thereby reimbursed for the entire Excess, the shortfall shall be rolled forward to be satisfied in the same manner by withholding from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of the next-to-occur payment event under any one of the CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid or in connection with which the Excess was partially satisfied).

Each party to the arbitration (which, for the avoidance of doubt, shall not include the Rights Agent) shall be responsible for its own attorney fees, expenses and costs of investigation.

Table of Contents

Section 2.3        No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The TR Beta CVRs shall be issued in book-entry form only and shall not be evidenced by a certificate or other instrument.

(b) The Rights Agent shall keep a register (the “TR Beta CVR Register”) for the registration of TR Beta CVRs. The Rights Agent is hereby initially appointed TR Beta CVR registrar and transfer agent (“TR Beta CVR Registrar”) for the purpose of registering TR Beta CVRs and transfers of TR Beta CVRs as herein provided. Upon any change in the identity of the Rights Agent, the successor Rights Agent shall automatically also become the successor TR Beta CVR Registrar.

(c) Every request made to transfer a TR Beta CVR must be in writing and accompanied by a written instrument or instruments of transfer and any other documentation requested by Buyer or TR Beta CVR Registrar, in a form reasonably satisfactory to Buyer and the TR Beta CVR Registrar, properly completed and duly executed by the registered Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, such signature to be guaranteed by a participant in a recognized Signature Guarantee Medallion Program. Upon receipt of such written request and materials, and all other reasonably necessary information, the TR Beta CVR Registrar shall register the transfer of the TR Beta CVRs in the TR Beta CVR Register. All duly transferred TR Beta CVRs registered in the TR Beta CVR Register shall be the valid obligations of Buyer, evidencing the same right and shall entitle the transferee to the same benefits and rights under this Agreement, as those previously held by the transferor. No transfer of a TR Beta CVR shall be valid until registered in the TR Beta CVR Register, and any transfer not duly registered in the TR Beta CVR Register will not be honored by Buyer or the Rights Agent until it is so registered, and then it will be honored only prospectively. Any transfer or assignment of the TR Beta CVRs shall be without charge (other than the cost of any tax or charge that may be payable in respect of such transfer or assignment, which shall be the responsibility of the transferor) to the Holder. The Rights Agent shall have no duty or obligation under any Section of this Agreement that requires the payment of taxes or charges unless and until it is satisfied that such taxes and/or charges have been or will be paid.

(d) A Holder may make a written request to the TR Beta CVR Registrar to change such Holder’s address of record in the TR Beta CVR Register. The written request must be duly executed by the Holder and conform to such other reasonable requirements as the Rights Agent may from time to time establish. Upon receipt of such proper written request, the TR Beta CVR Registrar shall promptly record the change of address in the TR Beta CVR Register.

(e) Upon reasonable written request of the Stockholders’ Representative, the Rights Agent shall (at the Stockholders’ Representative’s expense) promptly provide a copy of the TR Beta CVR Register to the Stockholders’ Representative.

Section 2.4        Payment Procedures.

(a) Promptly following the occurrence of a TR Beta CVR Payment Event, but in no event later than five Business Days after the occurrence of a TR Beta CVR Payment Event, Buyer shall deliver to the Rights Agent and the Stockholders’ Representative a certificate (the “Achievement Certificate”), certifying that the Holders are entitled to receive a TR Beta CVR Payment Amount (and setting forth the calculation of such TR Beta CVR Payment Amount), and shall also deliver to the Rights Agent the indicated TR Beta CVR Payment Amount in cash. Until such Achievement Certificate is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that a TR Beta CVR Payment Event has not occurred. No transaction described in Section 6.1(a) hereof shall give the Holders the right to receive a TR Beta CVR Payment Amount. Such cash amount deposited with the Rights Agent shall, pending its disbursement to such holders, be invested by the Rights Agent in (i) direct obligations of the United States of America, (ii) obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, or (iii) money market funds investing solely in a combination of the foregoing. Any interest and other income

resulting from such investments shall be applied first to the satisfaction of the Rights Agent Fees and Expenses, and any remainder (the “Remainder”) shall be paid to the Holders as set forth in Section 2.4(e) below. The Rights Agent must receive federal or other immediately available funds before 1:00 p.m., Eastern Time, on the funding date in order for such funds to be so invested on such date. Funds received after such time on the funding date will not be so invested until the following Business Day. Except as expressly provided above, the Rights Agent will not be obligated to calculate or pay interest to any Holder or any other party.

(b) If no TR Beta CVR Payment Event has occurred on or before the Outside Date, then, within five Business Days after the Outside Date, Buyer shall deliver to the Rights Agent and the Stockholders’ Representative a certificate, stating that the TR Beta CVR Payment Event did not occur. Such certificate is herein referred to as the “Non-Achievement Certificate.” Until such Non-Achievement Certificate is received by the Rights Agent, the Rights Agent shall have no duties or obligations with respect to the Outside Date, and the Rights Agent shall have no duties or obligations to monitor or determine the Outside Date.

(c) Subject to Section 5.16(a) of the Merger Agreement, within 45 calendar days after delivery by Buyer of a Non-Achievement Certificate or Achievement Certificate (the “Objection Period”), the Stockholders’ Representative may deliver a written notice to Buyer (with a copy to the Rights Agent) specifying that the Stockholders’ Representative objects to (i) the determination of Buyer that no TR Beta CVR Payment Event occurred on or before the Outside Date or (ii) the calculation of the TR Beta CVR Payment Amount, as applicable (a “Notice of Objection”), and stating the reason upon which the Stockholders’ Representative has determined that (A) the TR Beta CVR Payment Event has occurred on or before the Outside Date or (B) the calculation of the TR Beta CVR Payment Amount is in error, as applicable. Any dispute arising from a Notice of Objection shall be resolved in accordance with the procedure set forth in Section 7.12, which decision shall be binding on the parties hereto and every Holder.

(d) If a Notice of Objection with respect to a Non-Achievement Certificate has not been delivered to Buyer within the Objection Period, then the Holders shall have no right to receive the TR Beta CVR Payment Amount, and Buyer and the Rights Agent shall have no further obligations with respect to the TR Beta CVR Payment Amount. If a Notice of Objection with respect to an Achievement Certificate has not been delivered to Buyer within the Objection Period, then the Holders shall have no right to assert that the calculation of the TR Beta CVR Payment Amount is in error.

(e) If Buyer delivers an Achievement Certificate to the Rights Agent and the Stockholders’ Representative or if the TR Beta CVR Payment Amount is determined to be payable pursuant to Section 2.4(c) above, Buyer shall establish a TR Beta CVR Payment Date on the January 1 or July 1 which next follows the date of the Achievement Certificate or the date of final determination pursuant to Section 2.4(c) above, as applicable, and deliver written notice to the Rights Agent of such determination at least five (5) Business Days before such date. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that the TR Beta CVR Payment Date has not occurred. The Rights Agent shall have no duty or obligation to establish any payment amount or payment date with respect to the TR Beta CVR Payment Date. Upon receipt of such written notice and all other necessary information, the Rights Agent will, on such TR Beta CVR Payment Date, distribute the TR Beta CVR Payment Amount and the Remainder to the Holders (each Holder being entitled to receive its pro rata share of the TR Beta CVR Payment Amount and the Remainder based on the number of TR Beta CVRs held (as of the third Business Day before the TR Beta CVR Payment Date) by such Holder as reflected on the TR Beta CVR Register) by check mailed to the address of each such respective Holder as then reflected in the TR Beta CVR Register.

(f) Buyer shall be entitled to deduct and withhold, or cause to be deducted or withheld, from each TR Beta CVR Payment Amount otherwise payable pursuant to this Agreement, such amounts as Buyer or the applicable subsidiary of Buyer is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code, or any provision of state, local or foreign tax law. To the extent that amounts are so

withheld or paid over to or deposited with the relevant governmental entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made.

(g) On such date following the Outside Date as the holders of at least 20% of the outstanding General CVRs shall request via two Business Day prior written notice to the Stockholders’ Representative, the Stockholders’ Representative shall deliver to the Rights Agent in cash any amount remaining available in the Stockholders’ Representative Fund together with written instructions regarding the distribution of such amount (including the names and addresses of the applicable Holders and the breakdown of amounts to be distributed), and the Rights Agent will, within five Business Days of receipt of such instructions and amount (such date the “Fund Distribution Date”), distribute such amount in accordance with such instructions to the Holders of the General CVRs, the TR Beta CVRs, the Glucagon CVRs and the Roche CVRs (each Holder being entitled to receive its pro rata share of such amount based on the number of General CVRs, TR Beta CVRs, Glucagon CVRs and Roche CVRs held (as of the Fund Distribution Date) by such Holder as reflected in the General CVR Register, the TR Beta CVR Register, the Glucagon CVR Register and the Roche CVR Register (as defined herein and in the General CVR Agreement, the Glucagon CVR Agreement and the Roche CVR Agreement) by check mailed to the address of each such respective Holder as reflected in the General CVR Register, the TR Beta CVR Register, the Glucagon CVR Register and the Roche CVR Register as of the Close of Business on the last Business Day before the Fund Distribution Date. Until such written instructions are received by the Rights Agent, the Rights Agent shall not be obligated to take any action with respect to this paragraph. After the Fund Distribution Date, the Stockholders’ Representative shall be relieved of any and all duties and obligations under the Merger Agreement or any of the CVR Agreements.

(h) Subject to prior execution and delivery by the Stockholders’ Representative to Buyer and Target of a reasonable and customary confidentiality/nonuse agreement, Buyer shall promptly furnish to the Stockholders’ Representative all information and documentation in connection with this Agreement and the TR Beta CVRs that the Stockholders’ Representative may reasonably request in connection with the determination of whether a TR Beta CVR Payment Event has occurred or whether the calculation of a TR Beta CVR Payment Amount is in error, as applicable. Subject to prior execution and delivery by the applicable Holders to Buyer and Target of a reasonable and customary confidentiality/nonuse agreement, the Stockholders’ Representative may forward any information and documentation it receives to the Holders who request such information, but the Stockholders’ Representative covenants and agrees that in no event shall the Stockholders’ Representative provide any such information or documentation to any Holder who (i) is a Competitor of Buyer or (ii) holds fewer than 1% of the total number of TR Beta CVRs.

Section 2.5        No Voting, Dividends or Interest; No Equity or Ownership Interest in Buyer.

(a) The TR Beta CVRs shall not have any voting or dividend rights, and interest shall not accrue on any amounts payable on the TR Beta CVRs to any Holder.

(b) The TR Beta CVRs shall not represent any equity or ownership interest in Buyer (or in any constituent company to the Merger) or in any drug development program or Intellectual Property or other asset. The rights of the holders of TR Beta CVRs are limited to those expressly set forth in this Agreement, and such holders’ sole right to receive property hereunder is the right to receive cash from Buyer through the Rights Agent in accordance with the terms hereof.

Section 2.6        Sole Discretion and Decision Making Authority; No Fiduciary Duty.

Notwithstanding anything contained herein to the contrary, Buyer shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, (i) over any continued operation of, development of or investment in the TR Beta Program, (ii) over when (if ever) and whether to pursue, or enter into, a licensing agreement and/or sale agreement and/or similar transfer agreement

and/or agreement for the grant of an option to enter into any such transaction with respect to a drug candidate or technology or Intellectual Property from the TR Beta Program, and upon what terms and conditions, and (iii) over resolution of any third party claims relating to Contingent Payments.

Section 2.7        Satisfaction of Contingent Payments. Notwithstanding anything herein to the contrary:

(a) It is understood that upon the occurrence of certain payment events under this Agreement and the other CVR Agreements, the Landlord may be entitled to payments pursuant to the terms of Section 10 of the Landlord Agreement and the employees that were terminated in Target’s May 2009 reduction in force may be entitled to contingent severance payments pursuant to their respective severance arrangements (together, and including any payments to resolve claims arising in connection therewith, the “Contingent Payments”).

(b) In general, such Contingent Payments are to be satisfied first from amounts otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event, but in some instances the full amount payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event will be less than the Contingent Payments owing in respect of such payment event.

(c) In each case described in Section 2.7(b) above, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event will be paid by Buyer directly to the beneficiaries of the Contingent Payments rather than to or for the benefit of the holders of the CVRs under the applicable CVR Agreement, and the remainder of the Contingent Payments owing in respect of such payment event (the “Excess”) shall be paid by Buyer directly to the beneficiaries of the Contingent Payments.

(d) If an Excess is paid by Buyer pursuant to Section 2.7(c) of this Agreement or of any of the other CVR Agreements, then upon the next payment event under this Agreement or under any of the other CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid), Buyer shall withhold from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event, and shall keep for Buyer’s own account to reimburse Buyer for having paid the Excess, an amount equal to 100% of the Excess (or, if less, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event). If Buyer is not thereby reimbursed for the entire Excess, the shortfall shall be rolled forward to be satisfied in the same manner by withholding from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of the next-to-occur payment event under any one of the CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid or in connection with which the Excess was partially satisfied).

As it relates to the Rights Agent, this Agreement represents the entire understanding of the parties hereto with reference to the TR Beta CVRs and this Agreement supersedes any and all other oral or written agreements made with respect to the TR Beta CVRs.

Table of Contents

(b) The Rights Agent shall keep a register (the “Glucagon CVR Register”) for the registration of Glucagon CVRs. The Rights Agent is hereby initially appointed Glucagon CVR registrar and transfer agent (“Glucagon CVR Registrar”) for the purpose of registering Glucagon CVRs and transfers of Glucagon CVRs as herein provided. Upon any change in the identity of the Rights Agent, the successor Rights Agent shall automatically also become the successor Glucagon CVR Registrar.

(c) Every request made to transfer a Glucagon CVR must be in writing and accompanied by a written instrument or instruments of transfer and any other documentation requested by Buyer or Glucagon CVR Registrar, in a form reasonably satisfactory to Buyer and the Glucagon CVR Registrar, properly completed and duly executed by the registered Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, such signature to be guaranteed by a participant in a recognized Signature Guarantee Medallion Program. Upon receipt of such written request and materials, and all other reasonably necessary information, the Glucagon CVR Registrar shall register the transfer of the Glucagon CVRs in the Glucagon CVR Register. All duly transferred Glucagon CVRs registered in the Glucagon CVR Register shall be the valid obligations of Buyer, evidencing the same right and shall entitle the transferee to the same benefits and rights under this Agreement, as those previously held by the transferor.

Section 2.4        Payment Procedures.

(a) Promptly following the occurrence of a Glucagon CVR Payment Event, but in no event later than five Business Days after the occurrence of a Glucagon CVR Payment Event, Buyer shall deliver to the Rights Agent and the Stockholders’ Representative a certificate (the “Achievement Certificate”), certifying that the Holders are entitled to receive a Glucagon CVR Payment Amount (and setting forth the calculation of such Glucagon CVR Payment Amount), and shall also deliver to the Rights Agent the indicated Glucagon CVR Payment Amount in cash. Until such Achievement Certificate is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that a Glucagon CVR Payment Event has not occurred. No transaction described in Section 6.1(a) hereof shall give the Holders the right to receive a Glucagon CVR Payment Amount. Such cash amount deposited with the Rights Agent shall, pending its disbursement to such holders, be invested by the Rights Agent in (i) direct obligations of the United States of America, (ii) obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, or (iii) money market funds investing solely in a combination of the foregoing. Any interest and other income resulting from such investments shall be applied first to the satisfaction of the Rights Agent Fees and Expenses, and any remainder (the “Remainder”) shall be paid to the Holders as set forth in Section 2.4(e) below. The Rights Agent must receive federal or other immediately available funds before 1:00 p.m., Eastern Time, on the funding date in order for such funds to be so invested on such date. Funds received after such time on the funding

date will not be so invested until the following Business Day. Except as expressly provided above, the Rights Agent will not be obligated to calculate or pay interest to any Holder or any other party.

(b) If no Glucagon CVR Payment Event has occurred on or before the Outside Date, then, within five Business Days after the Outside Date, Buyer shall deliver to the Rights Agent and the Stockholders’ Representative a certificate, stating that the Glucagon CVR Payment Event did not occur. Such certificate is herein referred to as the “Non-Achievement Certificate.” Until such Non-Achievement Certificate is received by the Rights Agent, the Rights Agent shall have no duties or obligations with respect to the Outside Date, and the Rights Agent shall have no duties or obligations to monitor or determine the Outside Date.

(c) Subject to Section 5.16(a) of the Merger Agreement, within 45 calendar days after delivery by Buyer of a Non-Achievement Certificate or Achievement Certificate (the “Objection Period”), the Stockholders’ Representative may deliver a written notice to Buyer (with a copy to the Rights Agent) specifying that the Stockholders’ Representative objects to (i) the determination of Buyer that no Glucagon CVR Payment Event occurred on or before the Outside Date or (ii) the calculation of the Glucagon CVR Payment Amount, as applicable (a “Notice of Objection”), and stating the reason upon which the Stockholders’ Representative has determined that (A) the Glucagon CVR Payment Event has occurred on or before the Outside Date or (B) the calculation of the Glucagon CVR Payment Amount is in error, as applicable. Any dispute arising from a Notice of Objection shall be resolved in accordance with the procedure set forth in Section 7.12, which decision shall be binding on the parties hereto and every Holder.

(d) If a Notice of Objection with respect to a Non-Achievement Certificate has not been delivered to Buyer within the Objection Period, then the Holders shall have no right to receive the Glucagon CVR Payment Amount, and Buyer and the Rights Agent shall have no further obligations with respect to the Glucagon CVR Payment Amount. If a Notice of Objection with respect to an Achievement Certificate has not been delivered to Buyer within the Objection Period, then the Holders shall have no right to assert that the calculation of the Glucagon CVR Payment Amount is in error.

(e) If Buyer delivers an Achievement Certificate to the Rights Agent and the Stockholders’ Representative or if the Glucagon CVR Payment Amount is determined to be payable pursuant to Section 2.4(c) above, Buyer shall establish a Glucagon CVR Payment Date on the January 1 or July 1 which next follows the date of the Achievement Certificate or the date of final determination pursuant to Section 2.4(c) above, as applicable, and deliver written notice to the Rights Agent of such determination at least five (5) Business Days before such date. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively for all purposes that the Glucagon CVR Payment Date has not occurred. The Rights Agent shall have no duty or obligation to establish any payment amount or payment date with respect to the Glucagon CVR Payment Date. Upon receipt of such written notice and all other necessary information, the Rights Agent will, on such Glucagon CVR Payment Date, distribute the Glucagon CVR Payment Amount and the Remainder to the Holders (each Holder being entitled to receive its pro rata share of the Glucagon CVR Payment Amount and the Remainder based on the number of Glucagon CVRs held (as of the third Business Day before the Glucagon CVR Payment Date) by such Holder as reflected on the Glucagon CVR Register) by check mailed to the address of each such respective Holder as then reflected in the Glucagon CVR Register.

(f) Buyer shall be entitled to deduct and withhold, or cause to be deducted or withheld, from each Glucagon CVR Payment Amount otherwise payable pursuant to this Agreement, such amounts as Buyer or the applicable subsidiary of Buyer is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld or paid over to or deposited with the relevant governmental entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made.

Until such written instructions are received by the Rights Agent, the Rights Agent shall not be obligated to take any action with respect to this paragraph. After the Fund Distribution Date, the Stockholders’ Representative shall be relieved of any and all duties and obligations under the Merger Agreement or any of the CVR Agreements.

(h) Subject to prior execution and delivery by the Stockholders’ Representative to Buyer and Target of a reasonable and customary confidentiality/nonuse agreement, Buyer shall promptly furnish to the Stockholders’ Representative all information and documentation in connection with this Agreement and the Glucagon CVRs that the Stockholders’ Representative may reasonably request in connection with the determination of whether a Glucagon CVR Payment Event has occurred or whether the calculation of a Glucagon CVR Payment Amount is in error, as applicable. Subject to prior execution and delivery by the applicable Holders to Buyer and Target of a reasonable and customary confidentiality/nonuse agreement, the Stockholders’ Representative may forward any information and documentation it receives to the Holders who request such information, but the Stockholders’ Representative covenants and agrees that in no event shall the Stockholders’ Representative provide any such information or documentation to any Holder who (i) is a Competitor of Buyer or (ii) holds fewer than 1% of the total number of Glucagon CVRs.

Section 2.6        Sole Discretion and Decision Making Authority; No Fiduciary Duty.

Notwithstanding anything contained herein to the contrary, Buyer shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, (i) over any continued operation of, development of or investment in the Glucagon Program, (ii) over when (if ever) and whether to pursue, or enter into, a licensing agreement and/or sale agreement and/or similar transfer agreement and/or agreement for the grant of an option to enter into any such transaction with respect to a drug candidate or technology or Intellectual Property from the Glucagon Program, and upon what terms and conditions, and (iii) over resolution of any third party claims relating to Contingent Payments.

(a) It is understood that upon the occurrence of certain payment events under this Agreement and the other CVR Agreements, the Landlord may be entitled to payments pursuant to the terms of Section 10 of the Landlord Agreement and the employees that were terminated in Target’s May 2009 reduction in force may be entitled to contingent severance payments pursuant to their respective severance arrangements (together, and including any payments to resolve claims arising in connection therewith, the “Contingent Payments”).

(b) In general, such Contingent Payments are to be satisfied first from amounts otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event, but in some instances the full amount payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event will be less than the Contingent Payments owing in respect of such payment event.

(c) In each case described in Section 2.7(b) above, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event will be paid by Buyer directly to the beneficiaries of the Contingent Payments rather than to or for the benefit of the holders of the CVRs under the applicable CVR Agreement, and the remainder of the Contingent Payments owing in respect of such payment event (the “Excess”) shall be paid by Buyer directly to the beneficiaries of the Contingent Payments.

(d) If an Excess is paid by Buyer pursuant to Section 2.7(c) of this Agreement or of any of the other CVR Agreements, then upon the next payment event under this Agreement or under any of the other CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid), Buyer shall withhold from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event, and shall keep for Buyer’s own account to reimburse Buyer for having paid the Excess, an amount equal to 100% of the Excess (or, if less, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event). If Buyer is not thereby reimbursed for the entire Excess, the shortfall shall be rolled forward to be satisfied in the same manner by withholding from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of the next-to-occur payment event under any one of the CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid or in connection with which the Excess was partially satisfied).

To the extent that amounts are so withheld or paid over to or deposited with the relevant governmental entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made.

(g) On such date following the Outside Date as the holders of at least 20% of the outstanding General CVRs shall request via two Business Day prior written notice to the Stockholders’ Representative, the Stockholders’ Representative shall deliver to the Rights Agent in cash any amount remaining available in the Stockholders’ Representative Fund together with written instructions regarding the distribution of such amount (including the names and addresses of the applicable Holders and the breakdown of amounts to be distributed), and the Rights Agent will, within five Business Days of receipt of such instructions and amount (such date the “Fund Distribution Date”), distribute such amount in accordance with such instructions to the Holders of the General CVRs, the Glucagon CVRs, the TR Beta CVRs and the Roche CVRs (each Holder being entitled to receive its pro rata share of such amount based on the number of General CVRs, Glucagon CVRs, TR Beta CVRs and Roche CVRs held (as of the Fund Distribution Date) by such Holder as reflected in the General CVR Register, the Glucagon CVR Register, the TR Beta CVR Register and the Roche CVR Register (as defined herein and in the Glucagon CVR Agreement, the TR Beta CVR Agreement and the Roche CVR Agreement) by check mailed to the address of each such respective Holder as reflected in the General CVR Register, the Glucagon CVR Register, the TR Beta CVR Register and the Roche CVR Register as of the Close of Business on the last Business Day before the Fund Distribution Date. Until such written instructions are received by the Rights Agent, the Rights Agent shall not be obligated to take any action with respect to this paragraph. After the Fund Distribution Date, the Stockholders’ Representative shall be relieved of any and all duties and obligations under the Merger Agreement or any of the CVR Agreements.

(h) Subject to prior execution and delivery by the Stockholders’ Representative to Buyer and Target of a reasonable and customary confidentiality/nonuse agreement, Buyer shall promptly furnish to the Stockholders’ Representative all information and documentation in connection with this Agreement and the General CVRs that the Stockholders’ Representative may reasonably request in connection with the determination of whether a General CVR Payment Event has occurred or whether the calculation of a General CVR Payment Amount is in error, as applicable. Subject to prior execution and delivery by the applicable Holders to Buyer and Target of a

reasonable and customary confidentiality/nonuse agreement, the Stockholders’ Representative may forward any information and documentation it receives to the Holders who request such information, but the Stockholders’ Representative covenants and agrees that in no event shall the Stockholders’ Representative provide any such information or documentation to any Holder who (i) is a Competitor of Buyer or (ii) holds fewer than 1% of the total number of General CVRs.

Section 2.5        No Voting, Dividends or Interest; No Equity or Ownership Interest in Buyer.

(a) The General CVRs shall not have any voting or dividend rights, and interest shall not accrue on any amounts payable on the General CVRs to any Holder.

(b) The CVRs shall not represent any equity or ownership interest in Buyer (or in any constituent company to the Merger) or in any drug development program or Intellectual Property or other asset. The rights of the holders of General CVRs are limited to those expressly set forth in this Agreement, and such holders’ sole right to receive property hereunder is the right to receive cash from Buyer through the Rights Agent in accordance with the terms hereof.

Section 2.6        Sole Discretion and Decision Making Authority; No Fiduciary Duty.

Notwithstanding anything contained herein to the contrary, Buyer shall have sole discretion and decision making authority, which shall be exercised in good faith and with commercial reasonableness, (a) over any continued operation of, development of or investment in any or all of the General Programs, (b) over when (if ever) and whether to pursue, or enter into, a licensing agreement and/or sale agreement and/or similar transfer agreement and/or agreement for the grant of an option to enter into any such transaction with respect to a drug candidate or technology or Intellectual Property from any or all of the General Programs, the ‘7133 Program or the QM/MM Technology, and upon what terms and conditions, and (c) over resolution of any third party claims relating to Contingent Payments. Without limitation, in no event shall declining to effect a General Licensing Option Event, a General Licensing Event, a General Sale Option Event, a General Sale Event, a ‘7133 Event, a PeriCor Event or a QM/MM Event on terms and conditions that create a commercially unreasonable risk of liability on the part of Buyer be deemed not to satisfy the “in good faith and with commercial reasonableness” standard.

Section 2.7        Satisfaction of Contingent Payments. Notwithstanding anything herein to the contrary:

(a) It is understood that upon the occurrence of certain payment events under this Agreement and the other CVR Agreements, the Landlord may be entitled to payments pursuant to the terms of Section 10 of the Landlord Agreement and the employees that were terminated in Target’s May 2009 reduction in force may be entitled to contingent severance payments pursuant to their respective severance arrangements (together, and including any payments to resolve claims arising in connection therewith, the “Contingent Payments”).

(b) In general, such Contingent Payments are to be satisfied first from amounts otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event, but in some instances the full amount payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event will be less than the Contingent Payments owing in respect of such payment event.

(c) In each case described in Section 2.7(b) above, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such payment event will be paid by Buyer directly to the beneficiaries of the Contingent Payments rather than to or for the benefit of the holders of the CVRs under the applicable CVR Agreement, and the remainder of the Contingent Payments owing in respect of such payment event (the “Excess”) shall be paid by Buyer directly to the beneficiaries of the Contingent Payments.

Table of Contents

(d) If an Excess is paid by Buyer pursuant to Section 2.7(c) of this Agreement or of any of the other CVR Agreements, then upon the next payment event under this Agreement or under any of the other CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid), Buyer shall withhold from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event, and shall keep for Buyer’s own account to reimburse Buyer for having paid the Excess, an amount equal to 100% of the Excess (or, if less, 100% of the amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of such (new) payment event). If Buyer is not thereby reimbursed for the entire Excess, the shortfall shall be rolled forward to be satisfied in the same manner by withholding from any amount otherwise payable for the benefit of the holders of the CVRs under the applicable CVR Agreement in respect of the next-to-occur payment event under any one of the CVR Agreements (even if not the same CVR Agreement in connection with which the Excess was paid or in connection with which the Excess was partially satisfied).

(b) After expiration of the 30-day period contemplated by Section 7.12(a), such controversy or claim, including any claims for breach of this Agreement, shall be settled by arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules, and judgment on the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. Buyer and/or (subject to Section 5.16(a) of the Merger Agreement) the Stockholders’ Representative may initiate an arbitration for any matter relating to this Agreement.

The number of arbitrators shall be three. Within 15 days after the commencement of arbitration, each party shall select one person to act as arbitrator, and the two selected shall select a third arbitrator within 15 days of their appointment.

Annex F

Section 262 of the General Corporation Law of the State of Delaware

§ 262. Appraisal rights.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

Table of Contents

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is

required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

October 26, 2009

Board of Directors

Metabasis Therapeutics, Inc.

11119 North Torrey Pines Road

La Jolla, California 92037

Ladies and Gentlemen:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of the common stock of Metabasis Therapeutics, Inc. (the “Company”) of the Consideration (as defined below) to be received by such stockholders pursuant to the terms of the proposed Agreement and Plan of Merger (the “Merger Agreement”) to be entered into by and among Ligand Pharmaceuticals Incorporated (“Ligand”), Moonstone Acquisition, Inc., a wholly owned subsidiary of Ligand (“Merger Sub”), the Company and David F. Hale as Stockholders’ Representative.

As more specifically set forth in the Merger Agreement, and subject to the terms, conditions and adjustments set forth therein, the Merger Agreement provides for the acquisition of the Company by Ligand through the merger of Merger Sub with and into the Company with the Company as the surviving entity thereof (the “Merger”). By virtue of the Merger, each share of common stock issued and outstanding as of the effective time of the Merger (other than shares held by Ligand, the Company or any of their wholly owned subsidiaries and any Dissenting Shares (as defined in the Merger Agreement) will be converted into the right to receive (i) approximately $0.05 per share in cash (subject to adjustment) and (ii) certain contingent value rights (the “CVRs”) (collectively, the “Consideration”).

In connection with our review of the proposed Merger, and in arriving at our opinion, we have: (i) reviewed a draft of the Merger Agreement dated October 24 2009, as well as a draft, dated October 24, 2009, of the form of agreement pursuant to which the CVRs will be issued (collectively, the “Draft Transaction Documents”); (ii) reviewed certain financial information regarding the Company’s historical and projected financial performance provided to us by management, (iii) reviewed certain publicly available information concerning the Company; (iv) conducted interviews with members of current and former senior management concerning the matters described in clauses (ii) and (iii) above; (v) reviewed certain publicly available information regarding companies and transactions we deemed to be comparable, and (vi) reviewed such other financial studies and analyses and conducted such other investigations as we deemed necessary or appropriate for the purpose of rendering our opinion.

We have relied upon and assumed, without assuming liability or responsibility for independent verification, the accuracy and completeness of all information that was publicly available or was furnished, or otherwise made available, to us or discussed with or reviewed by or for us. We have further assumed that the financial information provided has been prepared on a reasonable basis in accordance with industry practice, and that management of the Company is not aware of any information or facts that would make any information provided to us incomplete or misleading. Without limiting the generality of the foregoing, for the purpose of this opinion, we have assumed that with respect to financial forecasts, estimates and other forward-looking information reviewed by us, that such information has been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments of the management of the Company as to the expected future results of operations and financial condition of the Company. We express no opinion as to any such financial forecasts, estimates or forward-looking information or the assumptions on which they were based.

In connection with our opinion, we have assumed and relied upon, without independent verification, the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by us. Our opinion does not address any legal, regulatory, tax or accounting issues.

In arriving at our opinion, we have assumed that the executed documents for the Merger (the “Transaction Documents”) will be in all material respects identical to the Draft Transaction Documents reviewed by us. We have relied upon and assumed, without independent verification, that (i) the representations and warranties of all parties set forth in the Transaction Documents and all related documents and instruments that are referred to therein are true and correct, (ii) each party to the Transaction Documents will fully and timely perform all of the covenants and agreements required to be performed by such party, (iii) the Merger will be consummated pursuant to the terms of the Transaction Documents without amendments thereto and (iv) all conditions to the consummation of the Merger will be satisfied without waiver by any party of any conditions or obligations thereunder. Additionally, we have assumed that all the necessary regulatory approvals and consents required for the Merger, including the approval of the stockholders of the Company, will be obtained in a manner that will not adversely affect the Company or the contemplated benefits of the Merger.

In arriving at our opinion, we have not performed any appraisals or valuations of any specific assets or liabilities (fixed, contingent or other) of the Company, and have not been furnished or provided with any such appraisals or valuations, nor have we evaluated the solvency of the Company under any state or federal law relating to bankruptcy, insolvency or similar matters. The analyses performed by us in connection with this opinion were going concern analyses. We express no opinion regarding the liquidation value of the Company or any other entity or the ability of the Company to operate as a going concern, whether or not the Merger is consummated. Without limiting the generality of the foregoing, we have undertaken no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which the Company or any of its affiliates is a party or may be subject, and at the direction of the Company and with its consent, our opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters.

This opinion is necessarily based upon the information available to us and facts and circumstances as they exist and are subject to evaluation on the date hereof; events occurring after the date hereof could materially affect the assumptions used in preparing this opinion. We are not expressing any opinion herein as to the price at which shares of Common Stock may trade following announcement of the Merger or at any future time or as to the price at which the CVRs may trade at any time after their issuance. We have not undertaken to reaffirm or revise this opinion or otherwise comment upon any events occurring after the date hereof and do not have any obligation to update, revise or reaffirm this opinion.

We have been engaged by the Company to act as its financial advisor and we will receive a fee from the Company for providing such services, including the provision of this opinion. Our fee is not contingent upon the consummation of the Merger. The Company has also agreed to indemnify us against certain liabilities and reimburse us for certain expenses in connection with our services. In the future, we may also provide other financial advisory and investment banking services to the Company and its affiliates, including Ligand, for which we would expect to receive compensation. In addition, in the ordinary course of our business, we and our affiliates may actively trade securities of the Company and/or Ligand for our own account or the account of our customers and, accordingly, may at any time hold a long or short position in such securities.

Consistent with applicable legal and regulatory requirements, Merriman Curhan Ford & Co. has adopted policies and procedures to establish and maintain the independence of our research departments and personnel. As a result, our research analysts may hold views, make statements or investment recommendations and/or publish research reports with respect to the Company, Ligand and/or the Merger that differ from the views of our investment banking personnel.

This opinion has been prepared solely for the information of the Board of Directors of the Company for its use in connection with its consideration of the Merger and is not intended to be and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote on any matter relating to the Merger or any other matter. Except with respect to the inclusion of this opinion in the Company’s proxy statement relating to the Merger in accordance with our engagement letter with the Company, this opinion shall not be disclosed, referred to, published or otherwise used (in whole or in part), nor shall any public references to us be made, without our prior written approval. This opinion has been approved for issuance by the Merriman Curhan Ford & Co. Fairness Opinion Committee.

This opinion addresses only the fairness, from a financial point of view, to the common stockholders of the Company of the proposed Consideration to be received by such stockholders in the Merger and does not address the relative merits of the Merger or any alternatives to the Merger, the Company’s underlying decision to proceed with or effect the Merger, or any other aspect of the Merger. This opinion does not address the fairness of the Merger to the holders of any other class of securities, creditors or other constituencies of the Company. This opinion is not a valuation of the Company or its assets or any class of securities of the Company. We have not evaluated the solvency or fair value of the Company. We are not experts in, nor do we express an opinion on, legal, tax, accounting or regulatory issues. We do not express an opinion about the fairness of the amount or nature of any compensation payable or to be paid to any of the officers, directors or employees, of the Company, whether or not relative to the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration to be received by the common stockholders of the Company in the Merger is fair, from a financial point of view, to such stockholders.

Sincerely,

/s/ Merriman Curhan Ford & Co.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

 

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

As permitted by Section 102 of the Delaware General Corporation Law, Ligand has adopted provisions in its certificate of incorporation and Bylaws that limit or eliminate the personal liability of its directors for a breach of their fiduciary duty of care as a director. The duty of care generally requires that, when acting on behalf of the corporation, directors exercise an informed business judgment based on all material information reasonably available to them. Consequently, a director will not be personally liable to Ligand or its stockholders for monetary damages or breach of fiduciary duty as a director, except for liability for: any breach of the director’s duty of loyalty to Ligand or its stockholders; any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law; any act related to unlawful stock repurchases, redemptions or other distributions or payment of dividends; or any transaction from which the director derived an improper personal benefit.

These limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission. As permitted by Section 145 of the Delaware General Corporation Law, the certificates of incorporation and Bylaws to be in effect upon the closing of this offering provide that: Ligand may indemnify its directors, officers, employees and agents to the fullest extent permitted by the Delaware General Corporation Law, subject to limited exceptions; Ligand may advance expenses to its directors and officers in connection with a legal proceeding to the fullest extent permitted by the Delaware General Corporation Law, subject to limited exceptions; and the rights provided in the certificates of incorporation and Bylaws are not exclusive.

In addition, Ligand has entered into separate indemnification agreements with its directors and officers which may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements may require Ligand, among other things, to indemnify its officers and directors against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements also may require Ligand to advance any expenses incurred by the directors or officers as a result of any proceeding against them as to which they could be indemnified. In addition, Ligand has purchased a policy of directors’ and officers’ liability insurance that insures its directors and officers against the cost of defense, settlement or payment of a judgment in some circumstances. These indemnification provisions and the indemnification agreements may be sufficiently broad to permit indemnification of Ligand’s officers and directors for liabilities, including reimbursement of expenses incurred, arising under the Securities Act.

In addition, for a period of six years following the effective time of the merger, Ligand will cause the surviving entity and its subsidiaries to fulfill and honor the obligations of Metabasis and its subsidiaries pursuant to each indemnification agreement in effect on the date of the merger agreement between Metabasis or any of its subsidiaries and each present or former director and officer of Metabasis and any indemnification provision and any exculpation provision in favor of each present or former director and officer of Metabasis that is set forth in the certificate of incorporation or bylaws of Metabasis and the equivalent organizational documents of any Metabasis subsidiary in effect as of the date of the merger agreement. The certificate of incorporation and bylaws of the surviving entity shall contain the provisions with respect to indemnification and exculpation from liability set forth in Metabasis’ certificate of incorporation and bylaws on the date of the merger agreement, and, from and after the effective time of the merger, such provisions shall not be amended, repealed or otherwise modified in any manner that could adversely affect the rights thereunder of any individual who is or was an officer or director of Metabasis at any time on or before the effective time of the merger.

Ligand will indemnify and hold harmless the present and former directors and officers of Metabasis against all liabilities arising out of the actions or omissions of such person’s service, including the advancement of certain expenses, for a period of six years following the effective time of the merger or for claims for which a written notice asserting such claim for indemnification before the sixth anniversary of the effective time until such time as such claim is fully and finally resolved.

 

II-1


Table of Contents

In addition, for a period of six years following the effective time of the merger, Ligand will cause the surviving entity to maintain in effect the current level and similar scope of directors’ and officers’ liability insurance coverage, provided that the surviving entity shall not be obligated to expend in any one year an amount in excess of $60,000.

ITEM 22.    UNDERTAKINGS

The undersigned registrant hereby undertakes:

(1) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(2) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(3) That every prospectus (i) that is filed pursuant to paragraph (2) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(4) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(5) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
