QIAGEN AND DIGENE ANNOUNCE MERGER

CREATING MARKET AND TECHNOLOGY LEADER IN MOLECULAR DIAGNOSTICS

Transaction Valued at Approximately US$1.6 Billion

Expected to be Accretive in 2008 to QIAGEN’s Earnings Per Share

Venlo, The Netherlands and Gaithersburg, Md., USA — June 3, 2007 – QIAGEN N.V. (Nasdaq: QGEN; Frankfurt, Prime Standard: QIA) and Digene Corp. (Nasdaq: DIGE) announced today a definitive agreement to combine the two companies to create market- and technology-leadership in molecular diagnostics. The Boards of Directors of both companies unanimously approved the transaction in which QIAGEN is to acquire 100% of Digene’s stock for a combination of cash and QIAGEN common stock. This strategic transaction combines QIAGEN’s leading portfolio of sample and assay technologies, including a broad panel of molecular diagnostic tests, with Digene’s leadership in HPV-targeted molecular diagnostic testing, creating a global leader in molecular diagnostics outside blood screening and viral load monitoring. It is anticipated that the combined company will have over US$350 million of molecular diagnostics revenues and more than US$800 million in revenues overall in 2008.

Under the terms of the agreement, the transaction will be effected as an exchange offer, followed by a merger of Digene into a subsidiary of QIAGEN. The acquisition consideration will consist of cash and QIAGEN stock, and Digene shareholders may elect to receive for each Digene share either US$61.25 in cash or 3.545 shares of QIAGEN stock, subject to pro-ration so that the total consideration issued for Digene stock consists of 55% cash and 45% QIAGEN stock. Based on the companies’ closing stock prices on June 1, 2007, the US$61.25 per share of consideration to be received by Digene shareholders represents a premium of 37% and total equity consideration of approximately US$1.6 billion, which includes US$170 million in cash. It is anticipated that the stock portion of the consideration will be tax-free to Digene shareholders and QIAGEN shareholders will own approximately 78% of the combined company on a fully diluted basis, and Digene shareholders will own approximately 22%.

QIAGEN is the world’s leading provider of sample and assay technologies for biological targets such as DNA, RNA and proteins. Through its technology-leading positions as well as through catalytic acquisitions, QIAGEN has created a molecular diagnostics franchise which, with approximately US$150 million in annual sales, is one of the largest in the industry. The company offers the world’s broadest portfolio of molecular diagnostic tests, which are available subject to regulatory approval in many countries of the world.

Digene holds a unique leadership position in molecular diagnostics. Digene’s primary product, the Digene^® HPV (human papillomavirus) Test, screens for the presence of high-risk types of the virus that have been shown to be the cause of cervical cancer. The Digene HPV Test is the only test for HPV that is both FDA-approved and CE-marked. This addresses one of the largest and most rapidly expanding market segments in women’s health and molecular diagnostics.

“The strategic rationale for this transaction is compelling as it combines QIAGEN’s leading technology portfolio and our breadth of molecular diagnostic tests with Digene’s leadership in what is seen as the fastest-growing segment of molecular diagnostics,” said Peer M. Schatz, Chief Executive Officer of QIAGEN. “This transaction creates significant value for our shareholders and instantaneous market and technology leadership in what is one of the most exciting areas of life sciences and healthcare: molecular diagnostics. The joint franchises link virology with oncology, thereby creating an exceptional platform to add next-generation and high-value molecular diagnostic products and strategically position the company for future growth.

“This transaction is an exciting and important next step for QIAGEN. It is consistent with our strategy to expand our leadership in sample and assay technologies. We are enthusiastic about the opportunity to combine our complementary strengths and collective resources as one company. This transaction provides us with many ways to drive top-line and bottom-line growth, such as access to new channels with existing and new products and combined technology, resources and infrastructure to provide greater operating strengths. This strategic transaction will be a catalyst for growth and, as such, we do not anticipate significant changes in the combined company’s workforce. We look forward to delivering the significant benefits of the combination to all of our shareholders and to working alongside Digene’s talented employees,” Mr. Schatz continued.

Daryl J. Faulkner, Chief Executive Officer and President of Digene, said, “This transaction provides our shareholders with immediate value as well as a unique opportunity to participate in the significant upside potential of a new entity that we believe will be a global leader in molecular diagnostics. We are extremely proud of the work we have done to develop and introduce the first HPV test to be both FDA -approved and CE-marked, and to build a business with an annual run rate of over US$200 million in revenues. We look forward to the enhanced opportunities that will result from this merger, which will allow the combined company to expand its geographic reach and offer a larger portfolio of products and services to address a broad spectrum of needs.

“We are pleased to be able to build on the successful partnership we have had with QIAGEN for more than a decade. We have collaborated on various projects, such as our current Rapid Capture^® System, which QIAGEN co-developed and manufactures. By accelerating this existing and productive working relationship, we anticipate future growth opportunities and have already begun to develop new products,” Mr. Faulkner continued.

Accretion

Based on preliminary analyses and assuming the transaction closes in the August/September time period, QIAGEN expects this transaction to contribute revenues of approximately US$58 to $60 million in the fourth quarter 2007 and approximately US$260 to $270 million for the full year of 2008. On an adjusted basis excluding one-time charges, integration and restructuring costs and amortization of acquired IP as well as equity based compensation (SFAS 123R), the acquisition is expected to dilute QIAGEN’s adjusted EPS by US$0.03 to $0.04 in the fourth quarter 2007. It is anticipated that the transaction will be accretive to QIAGEN’s adjusted EPS in 2008 by US$0.02 to $0.04. QIAGEN expects the transaction to be significantly accretive to earnings thereafter.

About Cervical Cancer and HPV

HPV is a family of common viruses, of which more than 30 types are transmitted through intimate (genital) skin-to-skin contact. The U.S. Centers for Disease Control and Prevention estimates that 6.2 million Americans acquire a new genital HPV infection every year and that 80% of women will be infected by the age of 50. Digene markets the only test that is both FDA-approved and CE-marked for detection of 13 high-risk types of HPV. Studies involving more than 200,000 women and spanning four continents have shown that the sensitivity of the Digene HPV Test is significantly higher than Pap (cytology) testing alone. HPV testing is typically performed in the same laboratories in which QIAGEN’s products are used. In addition, the new combined company will be uniquely positioned to facilitate HPV testing in under-served regions in both industrialized and developing countries.

QIAGEN Management and Headquarters

Following the close of the transaction, Peer M. Schatz will remain Chief Executive Officer of QIAGEN, Roland Sackers will remain Chief Financial Officer of QIAGEN and Daryl J. Faulkner will serve as co-head of the Integration Steering Committee. The combined company will be called “QIAGEN” with its U.S. headquarters in Maryland.

Use of Non-GAAP Financial Measures

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use the non-GAAP financial measure "adjusted EPS." Adjusted EPS excludes the write-off and amortization of acquisition-related intangible assets, and tax provisions/benefits related thereto. Adjusted EPS is not a measure of operating performance under GAAP. We believe that the use of adjusted EPS helps investors to gain a better understanding of our core operating results and future prospects, consistent with how management measures and forecasts our performance, especially when comparing such results to previous periods or forecasts. When analyzing our operating performance, investors should not consider adjusted EPS as a substitute for net income per share prepared in accordance with GAAP.

A-1

(“Company Common Stock”), issued and outstanding on the Acceptance Date, in exchange for, at the election of the holder thereof, and subject to Section 1.5(b)(iv), (i) for each share of Company Common Stock with respect to which an election to receive cash has been effectively made and not revoked (a “Cash Election”), the right to receive in cash from Parent, NAH or Merger Sub, as applicable, without interest, an amount equal to $61.25 (the “Per Share Cash Consideration”) or (ii) for each share of Company Common Stock with respect to which an election to receive common shares of Parent, €0.01 par value per share (“Parent Common Shares”), has been effectively made and not revoked (a “Stock Election”), the right to receive from Parent, NAH or Merger Sub, as applicable, 3.545 Parent Common Shares, and any cash to be paid in lieu of fractional Parent Common Shares pursuant to this Agreement (the “Per Share Stock Consideration” and, together with the Per Share Cash Consideration, as determined in accordance with Section 1.5, the “Consideration”); and (iii) for each share of Company Common Stock other than shares as to which a Cash Election or a Stock Election has been effectively made and not revoked (“Non-Election Shares”), the right to receive from Parent such Per Share Stock Consideration and/or Per Share Cash Consideration as is determined in accordance with Section 1.5.

(b) The Offer shall be subject only to (1) the condition that there shall be validly tendered in accordance with the terms of the Offer, prior to the expiration of the Offer, and not withdrawn, a number of shares of Company Common Stock that, together with the shares of Company Common Stock owned by Parent, NAH and Merger Sub, represents, at the expiration of the Offer, at least the Minimum Condition and (2) the other conditions set forth in Annex I hereto. Upon termination of this Agreement, if the Offer has not then been consummated, the Offer shall immediately expire and terminate without any shares of Company Common Stock being purchased thereunder. Parent, NAH and Merger Sub, as applicable, expressly reserve the right to waive any of the conditions to the Offer and to make any change in the terms of or conditions to the Offer; provided, however, that, without the prior written consent of the Company, no change may be made that: (i) decreases the consideration payable in the Offer; (ii) changes the form of consideration payable in the Offer to a form other than cash or Parent Common Shares; (iii) decreases the aggregate amount of Cash Consideration available in the Offer or decreases the relative amount of Cash Consideration available in the Offer; (iv) reduces the number of shares of Company Common Stock sought in the Offer; (v) imposes conditions to the Offer in addition to those set forth above or in Annex I; (vi) modifies or waives the Minimum Condition; (vii) except as provided below, changes the date on which the Offer is scheduled to expire; or (viii) makes any other change that is adverse to the holders of Company Common Stock or to holders that have elected a particular form of Consideration. Notwithstanding the foregoing, Parent, NAH and Merger Sub, as applicable, shall (or in the case of clause (iii) below, shall at their option) extend the Offer for one or more periods (i) beyond the scheduled expiration date, which shall initially be 25 Business Days following the commencement of the Offer, up to the Termination Date, if, at the scheduled or extended expiration date of the Offer, any of the conditions to the Offer shall not have been satisfied or, to the extent permitted, waived, until such conditions are satisfied or, to the extent permitted, waived, (ii) for any period required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer or any period required by applicable Law, or (iii) for an aggregate period of not more than 10 Business Days beyond the latest applicable date that would otherwise be permitted under clause (i) or (ii) of this sentence, if, as of such date, all of the conditions to the Offer have been satisfied or waived, but the number of shares of Company Common Stock validly tendered and not withdrawn pursuant to the Offer equals more than 80%, but less than 90% of the outstanding shares of Company Common Stock on a fully diluted basis; provided, however, that (x) Parent, NAH and Merger Sub, as applicable, shall not be obligated to extend the Offer pursuant to clause (i) of this sentence (but may elect to do so in accordance with this Section 1.1(b), provided that no such extension or series of extensions pursuant to this parenthetical that would extend the offer by more than 10 Business Days in the aggregate may be made without the prior written consent of the Company) if the Minimum Condition is not satisfied at the time such extension would otherwise be required, so long as the conditions set forth in Annex I have been satisfied, and Parent has publicly announced such fact and its intention not to extend the Offer at least two Business Days prior to the date such extension would, but for this proviso, otherwise have been required, (y) in the event Parent, NAH or Merger Sub, as applicable, elects to extend the expiration date pursuant to

A-2

clause (iii), Parent, NAH and Merger Sub shall be deemed to have irrevocably waived all of the conditions to the Offer set forth in Annex I, and (z) Parent’s, NAH’s and Merger Sub’s, as applicable, obligation to extend the Offer pursuant to clauses (i) or (ii) of this sentence is subject to such Parties’ respective rights to terminate this Agreement pursuant to Section 8. Except (A) as provided in clause (iii) of the previous sentence and (B) as elected by Parent in its sole discretion to extend the Offer for a period not to exceed 10 Business Days, Parent, NAH and Merger Sub, as applicable, shall not be permitted to extend the Offer without the prior written consent of the Company at the time that all conditions to the Offer have been satisfied or, to the extent permitted, waived. Parent, NAH or Merger Sub, as applicable, shall deliver a written notice to the Company (the “Acceptance Notice”) of its intention to accept for payment shares of Company Common Stock pursuant to the Offer one Business Day in advance of the proposed Acceptance Date. Subject to the foregoing and upon the terms and subject to the conditions of the Offer, Parent shall or shall cause NAH or Merger Sub to accept for payment or exchange, as promptly as reasonably practicable after the expiration of the Offer, all shares of Company Common Stock validly tendered and not withdrawn pursuant to the Offer.

(c) As soon as reasonably practicable on the date of commencement of the Offer, Parent shall, or Parent shall cause NAH or Merger Sub to, (i) file with the SEC a Tender Offer Statement on Schedule TO relating to the Offer, which shall include an offer to purchase and letter of transmittal/election form and such other ancillary documents as shall be required by applicable Law (together with any amendments or supplements thereto, the “Schedule TO”; and, together with the Offer Registration Statement and such other documents pursuant to which the Offer will be made, the “Offer Documents”), (ii) file with the SEC a registration statement on Form F-4 to register the offer and sale of Parent Common Shares pursuant to the Offer (the “Offer Registration Statement”) and (iii) disseminate the Offer Documents to holders of Company Common Stock. Each of the Company, Parent, NAH and Merger Sub shall use their reasonable efforts to have the Offer Registration Statement declared effective under the Securities Act as promptly as reasonably practicable after the filing thereof with the SEC and to keep the Offer Registration Statement effective as long as necessary to complete the Offer. Each of Parent, NAH and Merger Sub and the Company agree promptly to correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect. Parent shall, and Parent shall cause NAH or Merger Sub to, take all steps necessary to cause the Schedule TO and the Offer Registration Statement as so corrected to be filed with the SEC and the other Offer Documents as so corrected to be, at such time as reasonably agreed by Parent and the Company, disseminated to holders of shares of Company Common Stock, in each case as and to the extent required by applicable federal securities Laws. The Company and its counsel shall be given an opportunity to review and comment on the Offer Documents prior to their being filed with the SEC or disseminated to the holders of shares of Company Common Stock. Parent shall, and Parent shall cause NAH or Merger Sub to, provide the Company and its counsel with any comments Parent, NAH and Merger Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments and shall provide the Company and its counsel an opportunity to participate in the response of Parent, NAH or Merger Sub to such comments.

1.2 Company Action.

(a) The Company hereby consents to the Offer and represents that the Board of Directors of the Company (the “Company Board”), at a meeting duly called and held, has (i) determined that this Agreement and the Transactions are fair to and in the best interests of the Company and its stockholders, (ii) approved and declared advisable this Agreement and the Transactions in accordance with the DGCL, and (iii) resolved to recommend acceptance of the Offer and, as applicable, adoption of this Agreement by the Company’s stockholders (the “Recommendation”); provided, however, that the Company Board may withdraw, qualify, modify or amend the Recommendation as and only to the extent permitted by Section 5.2. The Company further represents that the Company Board has received the opinion of J.P. Morgan Securities Inc. to the effect that, as of the date of this Agreement, the consideration to be received by the holders of Company Common Stock (other than Parent, NAH, Merger Sub and their respective affiliates) in the Offer and the Merger is, taken

A-3

together, fair from a financial point of view to such holders, and a copy of such opinion, promptly upon receipt thereof, will be delivered to Parent. The Company hereby consents to the inclusion in the Offer Documents of the Recommendation and the Company shall not withdraw, qualify, modify or amend the Recommendation in any manner adverse to Parent, NAH or Merger Sub except as and only to the extent permitted by Section 5.2.

(b) The Company hereby agrees to file with the SEC contemporaneously with the commencement of the Offer and disseminate to holders of shares of Company Common Stock a Solicitation/Recommendation Statement on Schedule 14D-9 (together with any amendments or supplements thereto, the “Schedule 14D-9”) that, subject to Section 5.2, shall include the Recommendation. Parent and its counsel shall be given a reasonable opportunity to review and comment on the Schedule 14D-9 prior to its being filed with the SEC or disseminated to holders of shares of Company Common Stock. The Company agrees to provide Parent and its counsel with any comments that the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments and shall provide Parent and its counsel with a reasonable opportunity to participate in the response of the Company to such comments. Each of the Company and Parent agrees promptly to correct any information provided by it for use in the Schedule 14D-9 if and to the extent that it shall have become false or misleading in any material respect. The Company agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be, at such time as reasonably agreed by Parent and the Company, disseminated to holders of shares of Company Common Stock, in each case as and to the extent required by applicable federal securities Laws.

(c) The Company shall promptly furnish Parent with mailing labels containing the names and addresses of all record holders of shares of Company Common Stock and with security position listings of shares of Company Common Stock held in stock depositories, each as of a recent date, together with all other available listings and computer files containing names, addresses and security position listings of record holders and beneficial owners of shares of Company Common Stock. The Company shall promptly furnish Parent with such additional information, including, without limitation, updated listings and computer files of stockholders, mailing labels and security position listings, and such other assistance in disseminating the Offer Documents to holders of shares of Company Common Stock as Parent may reasonably request. Subject to the requirements of applicable Law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer or the Merger, Parent, NAH and Merger Sub shall hold in confidence the information contained in such labels, listings and files, shall use such information only in connection with the Transactions, and, if this Agreement shall be terminated in accordance with Section 8, shall deliver to the Company all copies of such information then in their possession.

1.3 Top-Up Option.

(a) Subject to the terms and conditions herein, the Company hereby grants to Parent an irrevocable, assignable option (the “Top-Up Option”) to purchase up to that number of shares of Company Common Stock (the “Top-Up Option Shares”) equal to the lowest number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock collectively owned by Parent, NAH and Merger Sub and any of their respective affiliates immediately following consummation of the Offer, shall constitute at least 90% of the Fully-Diluted Shares (assuming the issuance of the Top-Up Option Shares), at a purchase price per Top-Up Option Share equal to the Consideration, payable in Parent Common Shares, cash or a demand note at the sole discretion of Parent.

(b) Parent may, at its election, exercise the Top-Up Option, whether in whole or in part, at any one time after the occurrence of a Top-Up Exercise Event and prior to the Top-Up Termination Date. For the purposes hereof, a “Top-Up Exercise Event” shall occur upon Parent’s acceptance for payment pursuant to the Offer (including, without limitation, any subsequent offering that Parent may elect to extend pursuant to the terms and conditions of this Agreement) of shares of Company Common Stock constituting, together with shares of Company Common Stock owned directly or indirectly by any other affiliates of Parent, less

A-4

than 90% of the Fully-Diluted Shares, but only if (i) the issuance of the Top-Up Option Shares pursuant thereto would not require the approval of the stockholders of the Company under NASDAQ rules and regulations, or NASDAQ has granted a waiver from any such rule or regulation that is reasonably acceptable to the parties hereto, (ii) there is no other applicable law, rule or regulation that would require the approval of the Company’s stockholders for the issuance of the Top-Up Shares, or any such approval shall have been waived, (iii) there are sufficient shares of Company Common Stock available for issuance under the Company’s Certificate of Incorporation or available in the treasury of the Company, and (iv) any Parent Common Stock to be issued in connection with the exercise of the Top-Up Option may be issued pursuant to a valid exemption from the registration requirements of the Securities Act or any state securities laws. Upon and after the request of Parent, the Company shall use its reasonable best efforts to obtain any waiver contemplated by clause (i) of the preceding sentence from NASDAQ as promptly as possible after any such request. For the purposes hereof, the “Top-Up Termination Date” shall occur upon the earliest to occur of (A) the Effective Time, (B) the termination of this Agreement, (C) the date that is ten (10) Business Days after the occurrence of a Top-Up Exercise Event, unless the Top-Up Option has been previously exercised in accordance with the terms and conditions hereof and (D) the date that is ten Business Days after the Top-Up Notice Date, unless the Top-Up Closing shall have previously occurred.

(c) If Parent wishes to exercise the Top-Up Option, Parent shall send to the Company a written notice (a “Top-Up Exercise Notice,” and the date of receipt of which notice is referred to herein as the “Top-Up Notice Date”), specifying the place for the closing of the purchase and sale of shares of Company Common Stock pursuant to the Top-Up Option (the “Top-Up Closing”) and a date not earlier than one Business Day nor later than ten Business Days after the Top-Up Notice Date for the Top-Up Closing. The Company shall, promptly after receipt of the Top-Up Exercise Notice, deliver a written notice to Parent confirming the number of Top-Up Option Shares and the aggregate purchase price therefor.

(d) At the Top-Up Closing, subject to the terms and conditions of this Agreement, (i) the Company shall deliver to Parent a certificate or certificates evidencing the applicable number of Top-Up Option Shares; provided that the obligation of the Company to deliver Top-Up Option Shares upon the exercise of the Top-Up Option is subject to the condition that no provision of any applicable law or regulation and no judgment, injunction, order or decree shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Option Shares in respect of any such exercise and (ii) Parent shall purchase each Top-Up Option Share from the Company for the Consideration described above. Payment by Parent of the Consideration for the Top-Up Option Shares may be made, at Parent’s option, by delivery of (A) immediately available funds by wire transfer to an account designated by the Company, (B) a demand note issued by Parent in customary form and in a principal face amount equal to the purchase price for the Top-Up Option Shares or (C) Parent Common Shares.

(e) Upon the delivery by Parent to the Company of the Top-Up Exercise Notice, and the tender of the Consideration described in Section 1.3(d), Parent shall be deemed to be the holder of record of the Top-Up Option Shares issuable upon that exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing those Top-Up Option Shares shall not then be actually delivered to Parent or the Company shall have failed or refused to designate the bank account described in Section 1.3(d).

(f) Parent shall pay all expenses, and any and all federal, state and local stock transfer taxes and other related charges, that may be payable in connection with the preparation, issuance and delivery of stock certificates under this Section 1.3.

(g) Certificates evidencing Top-Up Option Shares delivered hereunder may include legends legally required, including a legend in substantially the following form:

1.4 Directors.

(a) Effective upon the Acceptance Date, Parent shall be entitled to designate the number of directors, rounded up to the next whole number, on the Company Board that equals the product of the (i) total number of directors on the Company Board (giving effect to the election of any additional directors pursuant to this Section 1.4) and (ii) the percentage that the number of shares of Company Common Stock beneficially owned by Parent, NAH or Merger Sub (including shares of Company Common Stock accepted for payment or exchange) bears to the total number of shares of Company Common Stock outstanding, and the Company shall take all action necessary to cause Parent’s designees to be elected or appointed to the Company Board, including increasing the number of directors, and seeking and accepting resignations of incumbent directors. At such time, the Company will also use its best efforts to cause individuals designated by Parent to constitute the number of members, rounded up to the next whole number, on (i) each committee of the Company Board and (ii) each board of directors of each Subsidiary of the Company identified by Parent (and each committee thereof) that represents the same percentage as such individuals represent on the Company Board, in each case only to the extent permitted by applicable Law. Notwithstanding the provisions of this Section 1.4, the parties hereto shall use their respective best efforts (including by reducing the number of directors that Parent may designate pursuant to the first sentence of this paragraph (a), but in no event to less than a majority of the directors on the Company Board) to ensure that at least two of the members of the Company Board shall, at all times prior to the Effective Time, be directors of the Company who were directors of the Company on the date hereof (the “Continuing Directors”); provided that if there shall be in office fewer than two Continuing Directors for any reason, the Company Board shall cause a person designated by the remaining Continuing Director to fill such vacancy who shall be deemed to be a Continuing Director for all purposes of this Agreement, or if no Continuing Directors then remain, the other directors of the Company then in office shall designate two persons to fill such vacancies who will not be officers or employees or affiliates of the Company, Parent, NAH or Merger Sub or any of their respective Subsidiaries and such persons shall be deemed to be Continuing Directors for all purposes of this Agreement.

(b) The Company’s obligations to appoint Parent’s designees to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The Company shall promptly take all actions, and shall include in the Schedule 14D-9 such information with respect to the Company and its officers and directors, as Section 14(f) and Rule 14f-1 require in order to fulfill its obligations under this Section, so long as Parent shall have provided to the Company on a timely basis in writing and be solely responsible for any information with respect to itself, NAH, Merger Sub and their respective nominees, officers, directors and affiliates required by Section 14(f) and Rule 14f-1.

(c) Following the election or appointment of Parent’s designees pursuant to Section 1.4(a) and until the Effective Time, the approval of a majority of the Continuing Directors shall be required to authorize any termination of this Agreement by the Company, any amendment of this Agreement requiring action by the Company Board, any extension of time for performance of any obligation or action hereunder by Parent, NAH or Merger Sub, any waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company, any amendment of the certificate of incorporation or by-laws of the Company, and any other action of the Company hereunder which adversely affects the holders of shares of Company Common Stock (other than Parent, NAH or Merger Sub).

1.5 Allocation of Consideration; Election Procedures.

(a) Allocation. Notwithstanding anything in this Agreement to the contrary, the maximum number of shares of Company Common Stock (the “Cash Election Number”) to be exchanged for Per Share Cash Consideration pursuant to the Offer shall be 55% of the number of whole shares of Company Common Stock that are tendered and accepted for payment or exchange pursuant to the Offer. The number of shares of Company Common Stock to be exchanged for Per Share Stock Consideration pursuant to the Offer (the “Stock Election Number”) shall be equal to the number of whole shares of Company Common Stock that are tendered and accepted for payment or exchange pursuant to the Offer less the Cash Election Number.

A-6

(b) Election Procedures.

(i) Subject to allocation and proration in accordance with the provisions of this Section 1.5, each record holder of shares of Company Common Stock issued and outstanding immediately prior to the Election Deadline (A) may specify in a request made in accordance with the provisions of this Section 1.5(b) (1) the number of shares of Company Common Stock owned by such holder with respect to which such holder desires to make a Cash Election and (2) the number of shares of Company Common Stock owned by such Holder with respect to which such Holder desires to make a Stock Election or (B) may indicate that such holder has no preference as to the receipt of Per Share Cash Consideration or Per Share Stock Consideration for such shares of Company Common Stock (a “Non-Election”). Shares of Company Common Stock in respect of which a Non-Election is made (“Non-Election Shares”) shall be deemed by Parent, in its sole and absolute discretion, subject to Section 1.5(b)(iv)-(vii), to be, in whole or in part, shares of Company Common Stock in respect of which Cash Elections or Stock Elections have been made.

(ii) Elections pursuant to Section 1.5(b)(i) shall be made on a form and with such other provisions to be reasonably agreed upon by the Company and Parent (a “Form of Election”) to be provided by the Exchange Agent for that purpose to holders of record of shares of Company Common Stock, together with appropriate transmittal materials, at the time of mailing to holders of record of shares of Company Common Stock of the Offer Documents. Elections shall be made by mailing to the Exchange Agent a duly completed Form of Election. To be effective, a Form of Election must be (x) properly completed, signed and submitted to the Exchange Agent at its designated office, by 5:00 p.m., on the Acceptance Date, (which date shall be publicly announced by Parent as soon as reasonably practicable but in no event less than five trading days prior to the Acceptance Date (the “Election Deadline”). The Company shall use its commercially reasonable efforts to make a Form of Election available to all persons who become holders of record of shares of Company Common Stock between the date of mailing described in the first sentence of this Section 1.5(b)(ii) and the Election Deadline. Parent shall determine, in its reasonable discretion, which authority it may delegate in whole or in part to the Exchange Agent, whether Forms of Election have been properly completed, signed and submitted or revoked. Neither Parent nor the Exchange Agent will be under any obligation to notify any person of any defect in a Form of Election submitted to the Exchange Agent. A holder of shares of Company Common Stock that tenders shares of Company Common Stock in the Offer and does not submit an effective Form of Election prior to the Election Deadline shall be deemed to have made a Non-Election.

(iii) An election may be revoked with respect to any shares of Company Common Stock, but only by written notice received by the Exchange Agent prior to the Election Deadline. Upon any such revocation, unless a duly completed Form of Election is thereafter submitted in accordance with Section 1.5(b)(i), such shares of Company Common Stock shall be Non-Election Shares.

(iv) In the event that the aggregate number of shares of Company Common Stock in respect of which Cash Elections have been made (collectively, the “Cash Election Shares”) exceeds the Cash Election Number (such excess the “Excess Cash Election Shares”), then:

1. all shares in respect of which Stock Elections have been made (the “Stock Election Shares”) shall be exchanged for Per Share Stock Consideration,

2. all Non-Election Shares shall be deemed converted into Stock Election Shares and exchanged for Per Share Stock Consideration,

3. all Excess Cash Election Shares shall be deemed converted into Stock Election Shares, on a pro-rata basis for each record holder of Cash Election Shares so that the number of Excess Cash Election Shares so converted, when added to the other Stock Election Shares, shall equal as closely as reasonably practicable the Stock Election Number, and all such Excess Cash Election Shares so converted shall be exchanged for Per Share Stock Consideration; and

A-7

4. all Cash Election Shares not deemed converted into Stock Election Shares pursuant to 3 above shall be exchanged for Per Share Cash Consideration.

(v) In the event that the aggregate number of Stock Election Shares exceeds the Stock Election Number (such excess the “Excess Stock Election Shares”), then:

1. all Cash Election Shares shall be exchanged for Per Share Cash Consideration,

2. all Non-Election Shares shall be deemed converted into Cash Election Shares and exchanged for Per Share Cash Consideration,

3. all Excess Stock Election Shares shall be deemed converted into Cash Election Shares, on a pro-rata basis for each record holder of Stock Election Shares, so that the number of Excess Stock Election Shares so converted, when added to the other Cash Election Shares, shall equal as closely as reasonably practicable the Cash Election Number, and all such Excess Stock Election Shares so converted shall be exchanged for Per Share Cash Consideration, and

4. all Stock Election Shares not deemed converted into Cash Election Shares pursuant to 3 above shall be exchanged for Per Share Stock Consideration.

(vi) In the event that neither clause (iv) nor clause (v) of this Section 1.5(b) is applicable, Non-Election Shares shall be deemed converted into Stock Election Shares on a pro rata basis for each record holder of Non-Election Shares such that the total number of Stock Election Shares equals the Stock Election Number and any remaining Non-Election Shares shall be deemed converted into Cash Election Shares, and (x) all Cash Election Shares and all Non-Election Shares which are deemed converted into Cash Election Shares shall be exchanged for Per Share Cash Consideration, and (y) all Stock Election Shares and all Non-Election Shares which are deemed converted into Stock Election Shares shall be exchanged for Per Share Stock Consideration.

(vii) The Exchange Agent, in consultation with Parent and the Company, shall make all computations to give effect to this Section 1.5(b).

1.6 Exchange of Certificates. The procedures for exchanging Company Certificates representing outstanding shares of Company Common Stock for the Consideration pursuant to the Offer are set forth below.

(a) Exchange Agent. Prior to the Acceptance Date, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as Exchange Agent in connection with the Offer (the “Exchange Agent”).

(b) Exchange Fund.

The Exchange Agent shall, pursuant to such irrevocable instructions, make cash payments and deliver the Parent Common Shares contemplated to be issued pursuant to this Agreement out of the Exchange Fund.

(c) Distributions on Parent Common Shares. For purposes of determining entitlement to dividends or other distributions declared on Parent Common Shares, holders of Company Common Stock who have validly tendered and not withdrawn such shares pursuant to the Offer shall be deemed to be record holders of Parent Common Shares as of the Acceptance Date, notwithstanding the fact that certificates representing such shares have not yet been issued or delivered to tendering stockholders (or, if applicable, appropriate book-entries have not yet been made).

(a) Subject to this Section 2, at the Effective Time, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Excluded Shares and Dissenting Shares) shall, by virtue of the Merger and without any action on the part of Parent, NAH, Merger Sub, the Company or the holder thereof, be converted into and shall become the right to receive the Consideration in accordance with the provisions of this Section 2, and each holder of a Company Certificate shall cease to have any rights with respect thereto other than, at the election of the holder thereof, (i) for each share of Company Common Stock with respect to which an election to receive cash has been effectively made and not revoked (a “Merger Cash Election”), the right to receive in cash, without interest, an amount equal to the Per Share Cash Consideration, (ii) for each share of Company Common Stock with respect to which an election to receive Parent Common Shares has been effectively made and not revoked (a “Merger Stock Election”), the right to receive the Per Share Stock Consideration, and (iii) for each share of Company Common Stock other than shares as to which a Merger Cash Election or a Merger Stock Election has been effectively made and not revoked (“Merger Non-Election Shares”), the right to receive from Parent such Per Share Stock Consideration and/or Per Share Cash Consideration as is determined in accordance with this Section 2.5.

(b) Allocation. Notwithstanding anything in this Agreement to the contrary, the maximum number of shares of Company Common Stock (the “Merger Cash Election Number”) to be converted into the right to receive Per Share Cash Consideration pursuant to the Merger shall be equal to 55% of the number of shares of Company Common Stock (other than Excluded Shares and Dissenting Shares) issued and outstanding immediately prior to the Effective Time. The number of shares of Company Common Stock to be converted

A-9

into the right to receive Per Share Stock Consideration pursuant to the Merger (the “Merger Stock Election Number”) shall be equal to the number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Excluded Shares and Dissenting Shares) less the Merger Cash Election Number.

(i) Any Merger Cash Election or Merger Stock Election shall be made on a form furnished by Parent for that purpose (a “Merger Form of Election”), which form may be part of the letter of election and transmittal delivered to former holders of shares of Company Common Stock promptly following the Effective Time. Holders of record who hold shares of Company Common Stock as nominees, trustees or in other representative capacities may submit multiple Merger Form of Election on behalf of their respective beneficial holders. To be effective, a Merger Form of Election must be properly completed, signed and submitted to the Exchange Agent at its designated office, within 45 calendar days after the Closing Date (the “Merger Election Deadline”). Parent shall determine, in its reasonable discretion, which authority it may delegate in whole or in part to the Exchange Agent, whether Merger Forms of Election have been properly completed, signed and submitted or revoked. Neither Parent nor the Exchange Agent will be under any obligation to notify any person of any defect in a Merger Form of Election submitted to the Exchange Agent. A holder of shares of Company Common Stock that does not submit an effective Merger Form of Election prior to the Merger Election Deadline shall be deemed to have made a Merger Non-Election.

(ii) Subject to allocation and proration in accordance with the provisions of this Section 2.5, each record holder of shares of Company Common Stock (other than Excluded Shares and Dissenting Shares) issued and outstanding immediately prior to the Effective Time (A) may specify in a request made in accordance with the provisions of this Section 2.5 (1) the number of shares of Company Common Stock owned by such holder with respect to which such holder desires to make a Merger Cash Election and (2) the number of shares of Company Common Stock owned by such Holder with respect to which such Holder desires to make a Merger Stock Election or (B) may indicate that such holder is making a Merger Non-Election for such shares of Company Common Stock. Merger Non-Election Shares shall be deemed by Parent, in its sole and absolute discretion, subject to Section 2.5(c)(iii)-(v), to be, in whole or in part, shares of Company Common Stock in respect of which Merger Cash Elections or Merger Stock Elections have been made.

(iii) In the event that the aggregate number of shares of Company Common Stock in respect of which Merger Cash Elections have been made (collectively, the “Merger Cash Election Shares”) exceeds the Merger Cash Election Number (such excess, the “Excess Merger Cash Election Shares”), then:

1. all shares in respect of which Merger Stock Elections have been made (the “Merger Stock Election Shares”) shall be converted into the right to receive Per Share Stock Consideration,

2. all Merger Non-Election Shares shall be deemed converted into Merger Stock Election Shares and shall be converted into the right to receive Per Share Stock Consideration,

3. all Excess Merger Cash Election Shares shall be deemed converted into Merger Stock Election Shares on a pro-rata basis for each record holder of Merger Cash Election Shares, so that the number of Excess Merger Cash Election Shares so converted, when added to the other Merger Stock Election Shares, shall equal as closely as reasonably practicable the Merger Stock Election Number, and all such Excess Merger Cash Election Shares so converted shall be converted into the right to receive Per Share Stock Consideration, and

4. all Merger Cash Election Shares not deemed converted into Merger Stock Election Shares pursuant to 3 above shall be converted into the right to receive Per Share Cash Consideration.

A-10

(iv) In the event that the aggregate number of Merger Stock Election Shares exceeds the Merger Stock Election Number (such excess, the “Excess Merger Stock Election Shares”), then:

1. all Merger Cash Election Shares shall be converted into the right to receive Per Share Cash Consideration,

2. all Merger Non-Election Shares shall be deemed converted into Merger Cash Election Shares and shall be converted into the right to receive Per Share Cash Consideration,

3. all Excess Merger Stock Election Shares shall be deemed converted into Merger Cash Election Shares, on a pro-rata basis for each record holder of Merger Stock Election Shares, so that the number of Excess Merger Stock Election Shares so converted, when added to the other Merger Cash Election Shares, shall equal as closely as reasonably practicable the Merger Cash Election Number, and all such shares of Excess Company Common Stock so converted shall be converted into the right to receive the Per Share Cash Consideration, and

4. all Merger Stock Election Shares not deemed converted into Merger Cash Election Shares pursuant to 3 above shall be converted into the right to receive Per Share Stock Consideration.

(v) In the event that neither clause (iii) nor clause (iv) of this Section 2.5 is applicable, Merger Non-Election Shares shall be deemed Merger Stock Election Shares on a pro rata basis for each record holder of Merger Non-Election Shares such that the total number of Merger Stock Election Shares equals the Merger Stock Election Number and any remaining Merger Non-Election Shares shall be deemed Merger Cash Election Shares, and (x) all Merger Cash Election Shares and all Merger Non-Election Shares in respect of which Merger Cash Elections are deemed to have been made shall be converted into the right to receive Per Share Cash Consideration, and (y) all Merger Stock Election Shares and all Merger Non-Election Shares in respect of which Merger Stock Elections are deemed to have been made shall be converted into the right to receive Per Share Stock Consideration.

(vi) The Exchange Agent, in consultation with Parent and the Company, shall make all computations to give effect to this Section 2.5.

2.6 Exchange of Certificates. The procedures for exchanging Company Certificates representing outstanding shares of Company Common Stock for the Consideration pursuant to the Merger are set forth below.

(a) Merger Exchange Fund. Immediately prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Company Common Stock, for exchange in accordance with the terms of the Merger, (i) the Merger Cash Pool plus an estimate of any cash to be paid in lieu of fractional Parent Common Shares pursuant to the Merger and (ii) certificates representing the Parent Common Shares issuable to holders of Company Common Stock in the Merger (such cash and certificates for Parent Common Shares, together with any dividends or distributions with respect thereto, being hereinafter referred to as, the “Merger Exchange Fund”). The Exchange Agent shall, pursuant to irrevocable instructions, make cash payments and deliver the Parent Common Shares contemplated to be issued pursuant to this Agreement out of the Merger Exchange Fund.

(b) Exchange Procedures. Upon surrender of a Company Certificate for cancellation to the Exchange Agent, together with a letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may reasonably be required pursuant to such instructions, the holder of such Company Certificate shall be entitled to receive promptly in exchange therefor (A) a certificate representing the number of whole Parent Common Shares that such holder has the right to receive as part of the Consideration and (B) a check for the cash that such holder is entitled to receive as part of the Consideration, including the Per Share Cash Consideration and cash in lieu of fractional shares. Until so surrendered, each outstanding Company Certificate shall be deemed from and after the Effective Time for all corporate purposes, to evidence the right to receive upon such surrender the Consideration. Any portion of the Parent Common Shares and cash deposited with the Exchange Agent pursuant to this Agreement, which remains undistributed to the holders of the shares of Company Common Stock for 12 months after the

A-11

Closing shall be delivered to Parent, upon demand, and any holders of shares of Company Common Stock who have not theretofore complied with this Section 2.6 shall thereafter be entitled to receive from Parent payment of the Consideration to be issued in exchange therefor and any cash in lieu of fractional shares, dividends or distributions with respect to Parent Common Shares to which such holders may be then entitled.

2.7 Payment for Parent Common Shares. The Parent Common Shares issued as Per Share Stock Consideration shall, for purposes of the Laws of The Netherlands, be paid for by the holder of the Company Common Stock through the subscription described below. By virtue of the Merger or the tendering of Company Common Stock in the Offer, as applicable, and without any further action on the part of the holders of Company Common Stock, each holder of Company Common Stock shall be deemed to have subscribed under this Agreement for the Parent Common Shares that are to be issued to such holder in accordance with this Agreement. In accordance with the Laws of The Netherlands, each holder of Company Common Stock who receives Parent Common Shares as part of such holder’s Consideration shall be obligated to pay up the Parent Common Shares so issued to such holder in accordance with this Agreement. This payment obligation on the part of such holders of Company Common Stock (which, solely for the purpose of satisfying this obligation to pay up the Parent Common Shares, shall be equal to the par value of such Parent Common Shares) shall be fully satisfied and paid by such holders of Company Common Stock by Parent’s assumption of such holder’s right to receive compensation (which, solely for the purpose of satisfying this obligation to compensate the holders of Company Common Stock, shall also be equal to the par value of such Parent Common Shares) from NAH for the cancellation of the Company Common Stock, or exchange of such Company Common Stock in connection with the consummation of the Offer, followed by a set off of this right to receive compensation against the obligation to pay up the Parent Common Shares. It is understood that, if the Merger or the Offer is consummated, the stockholders of the Company are entitled to receive the Parent Common Shares directly from Parent, NAH or Merger Sub and that, if the Merger or the Offer is consummated, such stockholders will thereupon become third party beneficiaries of this Agreement solely for this purpose. For the avoidance of doubt, (x) in no event shall the amount of the Consideration to be received by each holder of Company Common Stock pursuant to this Agreement be reduced by the obligation to pay up the Parent Common Shares and (y) NAH shall be obligated to deliver the Consideration to holders of Company Common Stock in accordance with, and subject to the terms of, this Agreement; provided, however, that the obligations of NAH to deliver the Consideration under this Agreement may be assigned, in whole or in part, to Parent or any of Parent’s wholly-owned direct or indirect Subsidiaries.

2.8 Certificate of Formation and Operating Agreement of the Surviving Company. At the Effective Time, (a) the Certificate of Formation of Merger Sub (the “Certificate of Formation”) immediately prior to the Closing shall continue in its then current form until amended as provided therein and under the DLLCA and (b) the Operating Agreement of Merger Sub (the “Operating Agreement”) immediately prior to the Closing shall continue in its then current form until amended as provided therein and under the DLLCA.

2.9 Directors and Officers. Subject to the requirements of Law, the persons listed on Schedule 2.9 shall be the officers of the Surviving Company immediately after the Closing, each to hold office in accordance with the Certificate of Formation and the Operating Agreement, in each case until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Formation and the Operating Agreement.

2.10 Cancellation of Shares. At the Effective Time, each share of Company Common Stock owned by Parent or any direct or indirect wholly owned Subsidiary of Parent immediately prior to the Effective Time (collectively, “Excluded Shares”), shall be canceled and extinguished without any conversion thereof or payment therefor.

2.11 No Liability. To the extent permitted by applicable Law, none of the Exchange Agent, Parent, NAH, Merger Sub or the Surviving Company shall be liable to a holder of shares of Company Common Stock for any Parent Common Shares or any amount of cash properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Law or retained by Parent.

A-12

2.12 Dissenting Shares. Notwithstanding anything to the contrary in this Agreement, any shares of Company Common Stock outstanding immediately prior to the Effective Time and held by a person who has not voted in favor of the Merger or consented thereto in writing and who has demanded appraisal for such shares in accordance with the DGCL (the “Dissenting Shares”) shall not be converted into a right to receive the Consideration, unless such holder fails to perfect or withdraws or otherwise loses its rights to appraisal or it is determined that such holder does not have appraisal rights in accordance with the DGCL. If, after the Closing, such holder fails to perfect or withdraws or loses its right to appraisal, or if it is determined that such holder does not have appraisal rights, such shares shall be treated as if they had been converted as of the Effective Time into the right to receive the Consideration. The Company shall give Parent, NAH and Merger Sub prompt notice of any demands received by the Company for appraisal of shares, and Parent, NAH and Merger Sub shall have the right to participate in all negotiations and proceedings with respect to such demands except as required by applicable Law. The Company shall not, except with prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, unless and to the extent required to do so under applicable Law.

2.13 Taking of Necessary Action; Further Action. If, at any time and from time to time after the Closing, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest in the Surviving Company full right, title, interest and possession of all properties, assets, rights, privileges, powers and franchises of the Company and Merger Sub, the officers and directors of the Surviving Company shall be and are fully authorized, in the name of and on behalf of any of the Company, Merger Sub or the Surviving Company, to take, or cause to be taken, all such lawful and necessary action as is not inconsistent with this Agreement.

2.14 Distributions With Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Closing with respect to Parent Common Shares with a record date after the Closing will be paid to the holder of any unsurrendered shares of Company Common Stock with respect to the Parent Common Shares represented thereby, and no cash in lieu of fractional Parent Common Shares shall be paid to any such holder, until the holder of record of the Company Certificate representing such Company Common Stock shall surrender such Company Certificate. Subject to Law, following surrender of any such Company Certificate, there shall be paid to the holder of record of such Company Certificate Parent Common Shares representing the whole number of Parent Common Shares to be issued in exchange therefor, the applicable Per Share Cash Consideration, any cash in lieu of fractional Parent Common Shares and any dividends or other distributions with a record date after the Closing theretofore paid with respect to such whole number of Parent Common Shares.

2.15 Transfers of Ownership. If any certificate for Parent Common Shares or check is to be issued in a name other than that in which the Company Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Company Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer, accompanied by all documents reasonably required to evidence and effect such transfer, and that the stockholder requesting such exchange shall have paid to Parent, or any agent designated by Parent, any transfer or other taxes required by reason of the issuance of a certificate for Parent Common Shares or a check in any name other than that of the registered holder of the certificate surrendered, or established to the reasonable satisfaction of Parent or any agent designated by it that such tax has been paid or is otherwise not payable.

2.16 Withholding of Tax. Parent, Surviving Company or the Exchange Agent will be entitled to deduct and withhold from the Consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Parent (or any Affiliate, including the Surviving Company) or the Exchange Agent are required to deduct and withhold with respect to the making of such payment under the Code or any provision of federal, state, local or foreign tax Law. To the extent that amounts are so withheld by Parent, Surviving Company or the Exchange Agent, such withheld amounts (i) shall be remitted by Parent, the Surviving Company or the Exchange Agent, as the case may be, to the applicable Governmental Authority and (ii) shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of whom such deduction and withholding were made by Parent.

A-13

2.17 Lost Certificates. If any Company Certificate is lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Company Certificate to be lost, stolen or destroyed, and an indemnification against loss in customary form, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Company Certificate the Consideration deliverable in respect thereof pursuant to this Agreement.

2.18 Company Equity Awards.

(a) At the Effective Time, all outstanding Company Equity Awards under the Amended and Restated Directors’ Equity Compensation Plan (the “Cancelled Equity Awards”) will be terminated or cancelled, as the case may be, in accordance with the terms of such plan and the agreements entered into thereunder. Prior to the Effective Time, the Company shall give any notice required by the Amended and Restated Directors’ Equity Compensation Plan, which notice shall have been provided to Parent for its review prior to delivery, to holders of Cancelled Equity Awards thereunder of (i) the acceleration in full of the vesting of such Cancelled Equity Awards, effective as of a date determined by the Company on or prior to the date of the Effective Time and (ii) the termination or cancellation, as the case may be, upon the Closing of any unexercised Cancelled Equity Awards.

(b) At the Effective Time, each outstanding Company Equity Award described in Section 3.3(e) of the Company Disclosure Schedule other than Cancelled Equity Awards (the “Assumed Equity Awards”), whether vested or unvested, shall be assumed by Parent and shall become an award with respect to, on the same terms and conditions as were applicable under the applicable Company Equity Plan immediately prior to the Effective Time, the number of Parent Common Shares determined as follows:

(i) the number of Parent Common Shares subject to each Assumed Equity Award shall be determined by multiplying the number of shares of Company Common Stock that were subject to such Assumed Equity Award immediately prior to the Effective Time by the Option Conversion Ratio (as defined below), and rounding the resulting number down to the nearest whole number of Parent Common Shares; and

(ii) the per share exercise price for the Parent Common Shares issuable upon exercise of each Assumed Equity Award shall be determined by dividing the per share exercise price of Company Common Stock subject to such Assumed Equity Award, as in effect immediately prior to the Effective Time, by the Option Conversion Ratio, and rounding the resulting exercise price up to the nearest whole cent;

provided, however, that the exercise price and the number of Parent Common Shares subject to each Company Equity Award shall be determined in a manner consistent with the requirements of Section 409A of the Code to the extent applicable; and provided, further, that in the case of any Company Equity Award to which Section 422 of the Code applies, the option price, the number of shares subject to such Company Equity Award and the terms and conditions of exercise of such Company Equity Award shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code.

(c) Any restriction on the exercise of any Assumed Equity Awards assumed by Parent shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Assumed Equity Awards shall otherwise remain unchanged as a result of the assumption of such Assumed Equity Awards, in each case except to the extent otherwise provided in any stock option, change in control or in any retention agreement in effect on the date of this Agreement. The “Option Conversion Ratio” shall be equal to 3.545.

(d) Following the Effective Time, Parent shall deliver to the participants in the Company Equity Plans holding Assumed Equity Awards an appropriate notice setting forth such participants’ rights pursuant to the Assumed Equity Awards, as provided in this Section 2.18.

(e) Parent shall take all corporate action necessary to reserve for issuance a sufficient number of Parent Common Shares for delivery upon exercise of the Assumed Equity Awards assumed in accordance with this Section 2.18. Within five (5) Business Days following the Effective Time, Parent shall file a registration statement on Form S-8 (or any successor form) with respect to the Parent Common Shares subject to such

A-14

Assumed Equity Awards held by persons who become employees or consultants of the Surviving Company and shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Assumed Equity Awards remain outstanding.

(f) The Company and Parent shall each take all corporate and other action reasonably necessary to cause all dispositions of equity securities of the Company (including Assumed Equity Awards) or acquisitions of equity securities of Parent (including any Assumed Equity Awards to acquire Parent Common Shares that may be granted by Parent) by each individual who (i) is a director or officer of the Company or (ii) at the Effective Time will become a director or officer of Parent, to be exempt under Rule 16b-3 of the Exchange Act.

2.19 Adjustments to Per Share Stock Consideration. The number of Parent Common Shares issuable in connection with the Offer and the Merger and the Option Conversion Ratio (and, in the case of any of the matters described in this Section 2.19 with respect to Company Common Stock, the Per Share Cash Consideration) shall each be appropriately adjusted, at any time and from time to time, to fully reflect the effect of any stock split or combination (splitsing van aandelen, samenvoeging van (verschillende klassen van) aandelen), recapitalization (omzetting reserves in aandelenkapitaal), stock dividend, reclassification, redenomination, adjustment of par value, exchange of shares, reorganization, recapitalization or other like change with respect to Parent Common Shares or, if permitted by the terms of Section 5.1(f), Company Common Stock, as the case may be, occurring (or for which a record date occurs) during the Interim Period.

2.20 No Fractional Shares. No certificate or scrip representing fractional Parent Common Shares shall be issued in connection with the Offer or the Merger, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. Each holder of shares of Company Common Stock exchanged pursuant to the Offer or the Merger who would otherwise be entitled to receive a fraction of a share of Parent Common Shares (after taking into account all Company Certificates delivered by such holder) shall receive from Parent, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a Parent Common Share multiplied by the Closing Average. For purposes of this Agreement, the “Closing Average” shall be the average closing sale price per share of Parent Common Shares (rounded up to the nearest cent) on the NASDAQ Global Select Market (“NGSM”) for the ten (10) consecutive trading days ending on the second-to-last trading day immediately prior to the Acceptance Date, in the case of the Offer or the Effective Time, in the case of the Merger.

Without limiting the generality of the foregoing, it is understood that any violation of any of the restrictions set forth in this Section 5.2 by any Representative of the Company or any of its Subsidiaries shall be and be deemed to be a breach by the Company of this Section 5.2 by the Company. Notwithstanding the foregoing and anything to the contrary contained in this Agreement, if, prior to the closing of the polls at the Company Special Meeting on the proposal to adopt this Agreement, the Company Board determines (after consultation with outside counsel and its financial advisor) that a Competing Proposal (other than one made following a breach by the Company of this Section 5.2) constitutes or is reasonably likely to lead to a Superior Competing Proposal, then the Company may, but only to the extent that the Company Board determines in good faith after consultation with the Company’s outside counsel that failure to do so would cause the Company Board to breach its fiduciary obligations under applicable Laws and subject to the Company providing prompt (but in any event within 12 hours) written notice to Parent of its decision to take such action and compliance by the Company with Section 5.2(d), (A) furnish information or data with respect to the Company and its Subsidiaries to such Third Party (and the Representatives of such Third Party); (B) participate in discussions and negotiations directly or through its Representatives with such Third Party, subject to, in the case of clause (A) and, to the extent such discussions or negotiations include the disclosure by the Company, any of its Subsidiaries, or any of their Representatives of any material nonpublic information, clause (B), a confidentiality agreement not less favorable to the Company than the Confidentiality Agreement, provided, that all such material nonpublic information not already provided or made available to Parent is provided to Parent as soon as reasonably practicable (but in any event within 12 hours) after it is provided to such Third Party and (C) amend, or grant a waiver or release under, any standstill or similar agreement with respect to any Company Common Stock, but only to the extent necessary to permit the making and subsequent consummation of a Superior Competing Proposal by a Third Party. For purposes of this Agreement, “Superior Competing Proposal” shall mean a bona fide written proposal or offer made by a Third Party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, sale of shares of stock, sale of assets, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, more than 50% of the capital stock of the Company then outstanding or more than 50% of the consolidated total assets of the Company and its Subsidiaries (i) on terms the Company Board determines in good faith (after consulting the Company’s outside legal counsel and financial advisor) are more favorable to the holders of Company Common Stock than the Transactions, taking into account, among other things, relevant legal, financial, regulatory, timing and other aspects of the offer and the Third Party making the offer and the terms and conditions of this Agreement and (ii) which is reasonably capable of being consummated.

Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, prior to obtaining the Company Requisite Stockholder Approval, the Company Board may, in response to a Superior Competing Proposal (other than one made following a breach by the Company of this Section 5.2), (1) withdraw or modify the Recommendation or (2) approve or recommend the Superior Competing Proposal, but in the case of any action described in clause (1) or any recommendation described in clause (2), only (x) if the Company Board determines in good faith, after consultation with the Company’s outside counsel, that failure to do so would violate its fiduciary obligations under applicable Laws, and in each case, only (y) at a time that is after 3 Business Days following Parent’s receipt of written notice advising Parent that the Company Board intends to take such action (during which period the Company shall make its chief executive officer, chief financial officer and its counsel available to Parent to meet on at least two separate occasions for a total of at least 12 hours, and shall consider in good faith any amendment of the terms of the Offer and/or the Merger proposed by Parent, NAH or Merger Sub or any proposal by Parent, NAH or Merger Sub to amend the terms of this Agreement, the Offer or the Merger), specifying therein the material terms and conditions of such Superior Competing Proposal and identifying the Person or group making such Superior Competing Proposal, provided that such 3 Business Day period shall be extended for an additional 3 Business Days following each material modification of such Competing Proposal occurring after the receipt of Parent’s proposal, and (z) if, after the end of such 3 Business Day period (plus each applicable extension), the Company Board determines in good faith (after consultation with the Company’s outside legal counsel and its financial advisor) that such proposed transaction continues to be a Superior Competing Proposal, after taking into account any bona fide proposal by Parent, NAH or Merger Sub to amend the terms of this Agreement and the Merger. The Company shall not during the term of this Agreement release any Third Party from, or agree to amend or waive any provision of, any confidentiality agreement with any Third Party with respect to a Competing Proposal entered into pursuant to this Section 5.2 other than the standstill provision as provided above, and the Company shall use its reasonable best efforts to enforce, to the fullest extent permitted by Law, each confidentiality agreement entered into pursuant to this Section 5.2. In addition, notwithstanding the foregoing or anything to the contrary set forth in this Agreement, prior to obtaining the Company Requisite Stockholder Approval, the Company Board may withdraw or modify the Recommendation if the Company Board determines, after consultation with outside counsel, that failure to do so would violate its fiduciary obligations under applicable Law, but only at a time that is after 3 Business Days following Parent’s receipt of written notice advising Parent that the Company Board is prepared to take such action, specifying the reasons therefor.

(d) In addition to the obligations set forth in Sections 5.2(a), (b) and (c), the Company shall notify Parent orally and, if requested by Parent, in writing, within 12 hours of the receipt by the Company of any Competing Proposal, which notification shall include the material terms and conditions of such Competing Proposal and the identity of the person or group making or sending the Competing Proposal. The Company shall promptly (but in any event within 12 hours) advise Parent of any material change in the terms or conditions of a Competing Proposal or any other material development with respect thereto.

A-48

(e) Nothing contained in this Section 5.2 or any other provision hereof shall prohibit the Company or the Company Board from (i) taking and disclosing to the Company’s stockholders pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act a position with respect to a tender or exchange offer by a Third Party or (ii) making any disclosure to the Company’s stockholders, if the Company Board determines, after consultation with its outside counsel, that failure to so disclose would cause it to violate its fiduciary obligations under applicable Law.

(f) Nothing in this Section 5.2 shall permit the Company to terminate this Agreement (except as expressly provided in Section 8).

5.3 No Control of Other Party’s Business. Nothing contained in this Agreement is intended to give Parent, directly or indirectly, the right to control or direct the Company’s or its Subsidiaries’ operations prior to the Effective Time, and nothing contained in this Agreement is intended to give the Company, directly or indirectly, the right to control or direct Parent’s or its Subsidiaries’ operations.

(i) Parent has advised the Company that Parent intends to seek financing of a portion of the aggregate Per Share Cash Consideration (“Financing”). The Parties agree that such Financing is not a condition to any Party’s obligation to effect the Merger and consummate the other transactions contemplated hereby in accordance with this Agreement, and that Parent, NAH and Merger Sub shall be required to proceed with the Closing notwithstanding Parent’s inability or failure to obtain such Financing.

9.5 Interpretation. When a reference is made in this Agreement to Sections, subsections, Schedules or Exhibits, such reference shall be to a Section, subsection, Schedule or Exhibit to this Agreement unless otherwise indicated. The words “include,” “includes” and “including” when used herein shall be deemed in each case to be followed by the words “without limitation.” The word “herein” and similar references mean, except where a specific Section or Section reference is expressly indicated, the entire Agreement rather than any specific Section or Section. The table of contents and the headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. References in this Agreement to a contract or agreement mean such contract or agreement as amended or otherwise modified from time to time. References in this Agreement to a Law include any rules, regulations and delegated legislation issued thereunder.

9.6 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

9.7 Entire Agreement. This Agreement (including all exhibits and schedules hereto), and other documents and instruments delivered in connection herewith constitute the entire agreement and supersede all prior agreements and undertakings (other than the Confidentiality Agreement), both written and oral, among the Parties with respect to the subject matter hereof.

9.8 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned by operation of Law or otherwise, except that Merger Sub may assign all or any of its rights hereunder to another wholly owned Subsidiary of Parent, provided that no such assignment shall relieve Parent, NAH or Merger Sub of its obligations hereunder. Subject to the preceding sentence, this Agreement shall be binding upon, and inure to the benefit of and be enforceable by, the parties hereto and their respective successors and assigns.

9.9 Parties in Interest. Except as set forth in Section 6.10(a) and Section 6.10(b), this Agreement is not intended, and shall not be deemed, to confer upon any person who is not a Party hereto any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

9.10 Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or delay on the part of any Party in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available.

9.11 Governing Law; Enforcement. This Agreement and the rights and duties of the Parties hereunder shall be governed by, and construed in accordance with, the law of the State of New York (except to the extent to which, under the internal affairs doctrine as applied under New York law, the DGCL applies by reason of being the Law of the Company’s and/or Merger Sub’s state of organization). The Parties agree that irreparable damage

A-62

would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which they are entitled at law or in equity.

(iv) the Company Board shall have withdrawn or modified, in any manner (other than non-substantive modifications), its approval or recommendation of the Offer or the Merger; or

(v) there shall have occurred (A) any general suspension of trading in securities on the New York Stock Exchange, the American Stock Exchange or on the NASDAQ, for a period in excess of twenty-four (24) hours (excluding suspensions or limitations resulting solely from physical damage or interference with such exchanges not related to market conditions), (B) a declaration of a banking moratorium or any suspension of payments in respect of banks in the United States (whether or not mandatory), (C) any limitation or proposed limitation (whether or not mandatory) by any United States Governmental Authority that has a material adverse effect generally on the extension of credit by banks or other financial institutions, (D) the commencement of a war involving the United States that, in the reasonable judgment of Parent, materially affects Parent, the Company, Parent’s ability to consummate the Offer or materially adversely affects securities markets in the United States generally or (E) in the case of any of the situations in clauses (A) through (D) of this paragraph existing at the time of the commencement of the Offer, a material acceleration or worsening thereof.

The failure by Parent, NAH or Merger Sub at any time to exercise any of the foregoing rights will not be deemed a waiver of any right, the waiver of such right with respect to any particular facts or circumstances shall not be deemed a waiver with respect to any other facts or circumstances, and each right will be deemed an ongoing right which may be asserted at any time and from time to time prior to the expiration of the Offer.

If the Offer is terminated, all tendered Shares not theretofore accepted for payment shall forthwith be promptly returned to the tendering stockholders.
