PROXY STATEMENT

2009 ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD JUNE 10, 2010

General

          The enclosed proxy is solicited on behalf of the board of directors of PROS Holdings, Inc. for use at the Annual Meeting of stockholders to be held Thursday, June 10, 2010 at 8:00 a.m., local time, at our corporate headquarters located at 3100 Main Street, Suite 900, Houston Texas, 77002, or at any adjournment or postponement thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting of Stockholders. Only stockholders of record at the close of business on April 16, 2010 are entitled to notice of and to vote at the meeting.

          These proxy solicitation materials and the Annual Report to Stockholders for the year ended December 31, 2009, including financial statements, were first mailed or made available on or about April 28, 2010 to stockholders entitled to vote at the meeting.

     The purposes of the meeting are:

	1.		To elect two directors for a three year term expiring 2013;
	2.		To ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2010; and
	3.		To transact such other business as may properly come before the meeting or any adjournment thereof.

          The board of directors unanimously recommends that stockholders vote “FOR” the proposals being presented.

Record date and shares outstanding

          Stockholders of record at the close of business on April 16, 2010 are entitled to notice of and to vote at the meeting. As of this record date 26,012,124 shares of our common stock were outstanding, all of which are entitled to vote with respect to all matters to be acted upon at the annual meeting. Each stockholder of record as of that date is entitled to one vote for each share of common stock held by him or her.

Vote required

          If a quorum is present, a plurality vote of the holders of our common stock entitled to vote and present or represented at the meeting is required for the election of a director. The affirmative vote of the holders of a majority of the shares of common stock present or represented by proxy and voting at the annual meeting is required to approve the ratification of the selection of our independent auditors. We will not count abstentions as either for or against a director, so abstentions have no effect on the election of a director. A properly executed proxy marked “abstain” with respect to any matter is considered entitled to vote, and thus, will have the effect of a vote against a matter, except for the election of directors.

          Our bylaws provide that a majority of the outstanding shares of our stock entitled to vote, whether present in person or represented by proxy, shall constitute a quorum for the transaction of business at the meeting. Votes for and against, abstentions and “broker non-votes” (shares held by a broker or nominee that does not have the authority, either express or discretionary, to vote on a particular matter) will each be counted as present for purposes of determining the presence of a quorum.

Effect of not casting your vote

          The New York Stock Exchange or the NYSE recently changed its broker discretionary rules to prohibit banks, brokers and other intermediaries to vote shares held in their clients’ accounts on elections of directors unless the client has provided voting instructions. In the past, if you held your shares in street name and you did not indicate how you wanted your shares voted in the election of directors, your bank or broker was allowed to vote those shares on your behalf in the election of directors as they felt appropriate. Recent rule changes take away the ability of your bank or broker to vote your uninstructed shares in the election of directors on a discretionary basis. Therefore, if you hold your shares in street name, it is important that you cast your vote if you want it to count in the election of directors (Proposal One of this proxy statement).

Attending the annual meeting

          The Annual Meeting will be held at 8:00 a.m., local time, on Thursday, June 10, 2010, at our corporate headquarters located at 3100 Main Street, Suite 900, Houston Texas, 77002. When you arrive, signs will direct you to the meeting room. Please note that the doors to the meeting room will not be open until 8:00 a.m. You do not need to attend the Annual Meeting to vote. Even if you plan to attend the Annual Meeting, please submit your vote in advance as instructed below.

Revocability of proxies

          Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is voted. Proxies may be revoked by:

	•		Filing with our Corporate Secretary at or before the taking of the vote at the meeting a written notice of revocation bearing a later date than the proxy;
	•		Duly executing a later-dated proxy relating to the same shares and delivering it to our Corporate Secretary at or before the taking of the vote at the meeting; or
	•		Attending the meeting and voting in person (although attendance at the meeting will not in and of itself constitute a revocation of a proxy).

          Any written notice of revocation or subsequent proxy should be delivered to PROS Holdings, Inc. at our headquarters located at 3100 Main Street, Suite 900, Houston Texas 77002, Attention: Corporate Secretary, or hand-delivered to our Corporate Secretary before the taking of the vote at the meeting.

Electronic delivery of PROS Holdings, Inc. stockholder communications

          We are pleased to take advantage of the U.S. Securities and Exchange Commission or the SEC rules that allow companies to furnish their proxy materials over the Internet. As a result, we are mailing to our stockholders a Notice of Internet Availability of Proxy Materials or the Notice instead of a paper copy of this proxy statement and our 2009 Annual Report. The Notice contains instructions on how to access those documents over the Internet. The Notice also contains instructions on how to request a paper copy of our proxy materials, including this proxy statement, our 2009 Annual Report and a form of proxy card or voting instruction card. As a result of the Notice, not all stockholders will receive a paper copy of our proxy materials.

Voting instructions

          To ensure that your vote is recorded promptly, please vote as soon as possible, even if you plan to attend the Annual Meeting in person. Most stockholders have three options for submitting their votes: (1) via the Internet, (2) by telephone or (3) by mail using the paper proxy card. If you have Internet access, we encourage you to record your vote on the Internet. It is convenient and it saves us significant postage and processing costs. In addition, when you vote via the Internet or by telephone prior to the meeting date, your vote is recorded immediately and there is no risk that postal delays will cause your vote to arrive late and therefore not be counted. If you attend the Annual Meeting, you may also submit your vote in person, and any previous votes that you submitted, whether by Internet, telephone or mail, will be superseded by the vote that you cast at the Annual Meeting.

	§		Vote by Internet. You can vote via the Internet. The website address for Internet voting is www.proxyvote.com. Have your proxy card in hand when you access the web site and follow the instructions to obtain your records and to create an electronic voting instruction form. You can use the Internet to transmit your voting instructions up until 11:59 P.M. Eastern Time on June 9, 2010. Internet voting is available 24 hours a day. If you vote via the Internet you do NOT need to vote by telephone or return a proxy card.
	§		Vote by Telephone. You can also vote by telephone by calling the toll-free telephone number provided on your proxy card. Have your proxy card in hand when you call and then follow the instructions. You may transmit your voting instructions from any touch-tone telephone up until 11:59 P.M. Eastern Time on June 9, 2010. Telephone voting is available 24 hours a day. If you vote by telephone you do NOT need to vote over the Internet or return a proxy card.
	§		Vote by Mail. If you received a printed copy of the proxy card, you can vote by marking, dating and signing it, and returning it in the postage-paid envelope provided to PROS Holdings, Inc., c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Please promptly mail your proxy card to ensure that it is received prior to the closing of the polls at the annual meeting

          If you are a beneficial owner, or you hold your shares in “street name,” please check your voting instruction card or contact your bank, broker or nominee to determine whether you will be able to vote by Internet or telephone.

Solicitation of proxies

          We will bear the expense of soliciting proxies in the enclosed form. In addition, we might reimburse banks, brokerage firms, and other custodians, nominees and fiduciaries representing beneficial owners of our common stock, for their expenses in forwarding soliciting materials to those beneficial owners. Proxies may also be solicited by our directors, officers or employees, personally or by telephone, telegram, facsimile or other means of communication. We do not intend to pay additional compensation for doing so.

Householding matters

          Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of this notice and proxy statement may have been sent to multiple stockholders in your household. If you would prefer to receive separate copies of a proxy statement either now or in the future, please contact our Corporate Communications Department by writing to our principal office at 3100 Main Street Suite 900, Houston, Texas 77002. Upon written request, we will provide a separate copy of this proxy statement. In addition, stockholders sharing an address can request delivery of a single copy of proxy statements if you are receiving multiple copies upon written request to our Corporate Secretary at the address stated above.

PROPOSAL ONE

          Our board of directors consists of seven directors, which are divided into three classes, each of whose members serve for a staggered three-year term. The term of office of one class of directors expires each year in rotation so that one class is elected at each Annual Meeting for a full three-year term. Our Class III directors, Albert E. Winemiller and Ronald F. Woestemeyer, have been nominated by the board of directors to fill a three-year term expiring in 2013. The two other classes of directors, who were elected or appointed for terms expiring at the annual meetings in 2011 and 2012, respectively, will remain in office.

          Unless a proxy is marked to withhold authority to vote, the proxy holders will vote the proxies received by them for the two Class III nominees named below, each of whom is currently a director and each of whom has consented to be named in this proxy statement and to serve if elected. In the event that any nominee is unable or declines to serve as a director at the time of the meeting, the proxies will be voted for any nominee designated by our board of directors to fill the vacancy. We do not expect that any nominee will be unable or will decline to serve as a director.

Vote required

          Election of a director requires the plurality vote of the holders of our common stock entitled to vote and present or represented at the meeting. Accordingly, the two nominees who receive the highest number of properly executed “FOR” votes from the holders of common stock, will be elected as directors. We will not count abstentions as either for or against a director, so abstentions have no effect on the election of a director.

          In accordance with Delaware law, abstentions will be counted for purposes of determining both whether a quorum is present at the meeting and the total number of shares represented and voting on this proposal. While broker non-votes will be counted for purposes of determining the presence or absence of a quorum, broker non-votes will not be counted for purposes of determining the number of shares represented and voting with respect to the particular proposal on which the broker has expressly not voted and, accordingly, will not affect the approval of this proposal.

          The NYSE recently changed its broker discretionary rules to prohibit banks, brokers and other intermediaries to vote shares held in their clients’ accounts on elections of directors unless the client has provided voting instructions. In the past, if you held your shares in street name and you did not indicate how you wanted your shares voted in the election of directors, your bank or broker was allowed to vote those shares on your behalf in the election of directors as they felt appropriate. Recent rule changes take away the ability of your bank or broker to vote your uninstructed shares in the election of directors on a discretionary basis. Therefore, if you hold your shares in street name, it is important that you cast your vote if you want it to count in the election of directors (Proposal One of this proxy statement).

The board of directors unanimously recommends voting “FOR” the two class III nominees listed below.

          The name of and certain information regarding each Class III nominee as of April 16, 2010 is set forth below, together with information regarding our Class I and Class II directors remaining in office. This information is based on data furnished to us by the nominees and directors. The business address for each nominee for matters regarding PROS Holdings Inc. is 3100 Main Street, Suite 900, Houston, TX 77002.

CORPORATE GOVERNANCE MATTERS

Board composition

          Our board of directors currently is comprised of seven directors. Mrs. Woestemeyer, Mrs. Keszler and Messrs. Petersen, Russell, Williams, Winemiller and Woestemeyer currently serve as our directors. Our bylaws provide that the number of directors constituting our board of directors shall be not more than nine, and the exact number of directors may be fixed or changed, by resolution adopted by the affirmative vote of a majority of the directors then in office. Our directors bring their leadership experience from a variety of information technology companies and professional backgrounds. Through Messrs. Winemiller, Woestemeyer and Mrs. Woestemeyer, we have the continuity and history of current and past management and direct relevant industry experience. Mrs. Keszler and Mr. Russell have worked in various senior management roles and contribute their significant operational experience. Messrs. Petersen and Williams have experience in the role of chief financial officer and bring their extensive accounting and risk management knowledge to us. In addition, our directors’ objective and sound judgment, high ethical standards, core values, inquisitive nature, insight, integrity, intelligence, thoughtfulness, and constructive working relationships with other directors are reflected in their contributions to our board and committee meetings and our direction and strategy as a company.

Independence of Directors

          The board of directors has adopted categorical standards or guidelines to assist our board of directors in making its independence determinations with respect to each director. These standards are published in our Corporate Governance Guidelines and are available under the Corporate Governance – Investor Relations section of our website at www.prospricing.com. The board of directors has determined that the following four directors are independent within the meaning of the NYSE listing standards and federal securities laws: Messrs. Petersen, Russell and Williams and Mrs. Keszler. As part of such determination of independence, our board of directors has affirmatively determined that none of these four directors have a relationship with us that would interfere with the exercise of independent judgment in carrying out their responsibilities as directors. A majority of our board of directors is independent, and our audit committee, compensation committee and nominating and governance committee is comprised of all independent directors.

Meeting attendance

          During 2009, our board of directors held seven meetings, the audit committee held 14 meetings, the compensation committee held eight meetings, and the nominating and governance committee held four meetings. No incumbent director attended fewer than 100% of the aggregate of all meetings of our board of directors, and the committees on which he or she served, during 2009. The board of directors encourages all directors to attend meetings of the stockholders. All directors attended the 2009 meeting of the stockholders.

Director nomination

          The nominating and governance committee of our board of directors has the responsibility for establishing the criteria for recommending which directors should stand for re-election to our board of directors and the selection of new directors to serve on our board of directors. In addition, the nominating and governance committee is responsible for establishing the procedures for our stockholders to nominate candidates to our board of directors. Although the nominating and governance committee has not formulated any specific minimum qualifications for director candidates, it has determined that desirable characteristics include, but are not limited to, business experience, mature judgment, personal and professional ethics, and integrity and values. The Company does not have a formal policy with respect to consideration of diversity in identifying director nominees, however, in the process of selecting a director nominee, the nominating and governance committee assesses backgrounds and expected contributions of the individuals to the Board. These and other standards are published in our Corporate Governance Guidelines and are available under the Corporate Governance – Investor Relations section of our website at www.prospricing.com.

          Our bylaws permit any stockholder of record to nominate directors. Stockholders who wish to submit nominees for election at an annual or special meeting of stockholders should follow the procedure described on page 30. The nominating and governance committee applies the same standards in considering candidates submitted by stockholders as it does in evaluating candidates submitted by members of the board of directors.

Committees of the board of directors

          Our board of directors has established an audit committee, a compensation committee and a nominating and governance committee. In addition, the board of directors has elected a lead independent director. The table below presents the members of each of our committees and the lead independent director.

In arriving at this determination, the board has examined each member’s scope of experience and the nature of their employment in the corporate finance sector.

          The audit committee oversees our accounting and financial reporting processes and the audits of our financial statements. Primary responsibilities of our audit committee include:

	•		conferring with management and our independent auditors regarding the scope, adequacy and effectiveness of our internal control over financial reporting;
	•		establishing procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal control or auditing matters and for the confidential, anonymous submission by our employees of concerns regarding questionable accounting or auditing matters; and
	•		reviewing and approving all related party transactions.

         Our audit committee operates under a written charter, a copy of which is available under the Corporate Governance – Investor Relations section of our website at www.prospricing.com. A printed copy of our audit committee charter may be obtained by any stockholder upon sending a written request to PROS Holdings, Inc., 3100 Main Street, Suite 900, Houston, Texas 77002, Attn: Corporate Communications.

Each member of our compensation committee is a non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act, and an outside director, as defined pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code. Our board of directors has determined that Messrs. Petersen, Russell and Williams each meet the independence requirements of the NYSE listing standards and federal securities laws.

          The compensation committee discharges the responsibilities of our board of directors relating to the compensation and benefits for our executive officers and directors. Primary responsibilities of our compensation committee include:

	•		determining and reviewing all forms of compensation for our executive officers and directors, including, among other things, annual salaries, bonuses, equity awards, severance arrangements, change in control protections and other compensatory arrangements;
	•		reviewing and approving corporate performance goals and objectives relevant to such compensation;
	•		administering our equity incentive plans and granting awards of options and other equity-based awards to our executive officers, directors and employees;
	•		reviewing our compensation discussion and analysis and compensation committee report required by the rules of the SEC; and
	•		evaluating and recommending to our board of directors the compensation plans and programs advisable for us, and evaluating and recommending the modification or termination of existing plans and programs.

     Nominating and governance committee

          The members of the nominating and governance committee are Messrs. Petersen, Russell and Williams and Mrs. Keszler. The board has determined that each member meets the independence requirements of the NYSE listing standards and federal securities laws. Primary responsibilities of our nominating and governance committee include:

	•		identifying, evaluating and recommending to our board of directors candidates to serve as members of our board of directors and considering the nomination of our incumbent directors for reelection;
	•		evaluating stockholder nominations of candidates for election to our board of directors;
	•		reviewing our general policy relating to selection of director candidates and members of committees of our board of directors, including an assessment of the performance of our board of directors; and
	•		reviewing and making recommendations to our board of directors regarding corporate governance principles.

         Our nominating and governance committee operates under a written charter, a copy of which is available under the Corporate Governance – Investor Relations section of our website at www.prospricing.com. A printed copy of our nominating and governance committee charter may be obtained by any stockholder upon sending a written request to PROS Holdings, Inc., 3100 Main Street, Suite 900, Houston, Texas 77002, Attn: Corporate Communications. In 2009, the nominating and governance committee held four in-person meetings.

Board Leadership Structure

          The board of directors has determined that combining the chief executive officer and chairman positions is the appropriate leadership structure for PROS Holdings, Inc. at this time. The board of directors believes that combining the chief executive officer and chairman roles fosters clear accountability, effective decision-making and alignment on corporate strategy. The board of directors believes this leadership structure is particularly appropriate for the Company at this time given the chief executive officer’s continuity of service with the Company since 1999. Nevertheless, the board of directors believes the decision of whether to combine or separate the positions of chief executive officer and chairman will vary company to company and depend upon a company’s particular circumstances at a given point in time. Accordingly, the board of directors intends to carefully consider from time to time whether the chief executive officer and chairman positions should be combined based on what the board of directors believes is best for the Company and its stockholders.

          The board of directors believes that an effective leadership structure could be achieved either by combining or separating the chief executive officer and chairman positions, if the structure encourages the free and open dialogue of competing views and provides for strong checks and balances. Specifically, an effective governance structure must balance the powers of the chief executive officer and the independent directors and ensure that the independent directors are fully informed, able to discuss and debate the issues that they deem important, and able to provide effective oversight of management.

          The board of directors has elected a non-management director to serve in a lead capacity (“lead independent director”) to coordinate the activities of the other non-management directors, and to perform any other duties and responsibilities that the board of directors may determine. While the board of directors elects a lead independent director, it is generally expected that he or she will serve for more than one year. Mr. Russell was elected to serve as lead independent director effective November 20, 2008.

          The role of the lead independent director includes:

	•		presiding at non-management executive sessions, with the authority to call meetings of the independent directors;
	•		presiding at executive sessions;
	•		functioning as principal liaison on Board-wide issues between the independent directors and the Chairman;
	•		if requested by shareholders, ensuring that he/she is available, when appropriate, for consultation and direct communication.

         The lead independent director operates under a written charter, a copy of which is available under the Corporate Governance – Investor Relations section of our website at www.prospricing.com.

          The board of directors believes that the lead independent director position will balance the need for effective and independent oversight of management with the need for strong, unified leadership. The board of directors believes that this structure is in the best interest of PROS Holdings, Inc. as it will allow for a balance between the chief executive officer and chairman and the independent directors and will provide an environment in which its independent directors are fully informed, have significant input into the content of board of directors meeting agendas and are able to provide objective and thoughtful oversight of management.

Executive Sessions

          Executive sessions, which are meetings of the non-employee members of the board of directors, are regularly scheduled throughout the year. Non-employee directors meet by themselves, without management or employee-directors present, at every regularly scheduled in-person board of directors meeting. Non-employee directors and independent directors may hold other such sessions at the request of any non-employee director or independent director. Non-employee and independent directors shall notify the Lead Independent Director if they would like to hold such a session, and the Lead Independent Director will facilitate the scheduling of such a session. Executive sessions (whether of the non-employee directors or independent directors) will be led by Lead Independent Director.

Oversight of Risk Management

          The board of directors oversees the Company’s risk management process. Management reviews the process, including identification of key risks and steps taken to address them, with the full board of directors on a periodic basis. Although the full board of directors is responsible for this oversight function, the audit committee, the compensation committee, and the nominating and governance committee assist the board of directors in discharging its oversight duties.

          The compensation committee reviews risks related to the subject matters enumerated in its charter, including risks associated with the Company’s compensation programs. The nominating and governance committee considers risks related to the subject matters for which it is responsible as identified in its charter, including risks associated with corporate governance. Similarly, the audit committee considers risks related to the subject matters enumerated in its charter, including risks relating to internal controls, disclosure, and financial reporting.

          Accordingly, while each of the three committees contributes to the risk management oversight function by assisting the board of directors in the manner outlined above, the board of directors itself remains responsible for the oversight of the Company’s risk management program.

Compensation committee interlocks and insider participation

          No member of our compensation committee and none of our executive officers has any relationships that would constitute an interlocking relationship with executive officers and directors of any another entity.

Director compensation

          Under our 2009 director compensation policy, our non-employee members of our board of directors received an annual retainer of $27,000 and a retainer of $13,000 if such director also serves on our audit committee or compensation committee. All fees are paid on a quarterly basis. We have also agreed to reimburse our directors for reasonable out-of-pocket expenses incurred in connection with their attendance at our board of directors or committee meetings.

          In addition, each non-employee members of our board of directors received a grant of 5,000 restricted stock units, the chairman of the audit committee, the lead independent director and the chairman of the nominating and governance committee received a grant of 5,000 restricted stock units, and the chairman of the compensation committee received a grant of 2,500 restricted stock units. These grants of restricted stock units vested on January 1, 2010.

Corporate governance guidelines

          We believe in sound corporate governance practices and have adopted formal Corporate Governance Guidelines to enhance our effectiveness. Our board of directors adopted these Corporate Governance Guidelines in order to ensure that it has the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The Corporate Governance Guidelines are also intended to align the interests of directors and management with those of our stockholders. The Corporate Governance Guidelines set forth the practices our board of directors follows, including, but not limited to, with respect to board of directors and committee composition and selection, director responsibilities, director access to officers and employees and chief executive officer performance evaluation and succession planning. A printed copy of our Corporate Governance Guidelines may be obtained by any stockholder upon sending a written request to PROS Holdings, Inc., 3100 Main Street, Suite 900, Houston, Texas 77002, Attn: Corporate Communications. A copy of our Corporate Governance Guidelines is also available under the Corporate Governance – Investor Relations section of our website at www.prospricing.com.

Code of business conduct and code of ethics

          Our board of directors has adopted a Code of Business Conduct and Ethics that applies to all of our directors and employees. We will provide copies of our Code of Business Conduct and Ethics without charge upon request. A printed copy of our Code of Business Conduct and Ethics may be obtained by any stockholder upon sending a written request to PROS Holdings, Inc., 3100 Main Street, Suite 900, Houston, Texas 77002, Attn: Corporate Communications. Our Code of Business Conduct and Ethics is also available under the Corporate Governance – Investor Relations section of our website at www.prospricing.com.

Communications with our board of directors

          Stockholders or interested parties who wish to communicate with members of our board of directors, including the independent directors individually or as a group, may send correspondence to them in care of our Corporate Secretary at 3100 Main Street, Suite 900, Houston, TX 77002. Such communication will be forwarded to the intended recipient(s). We currently do not intend to have our Corporate Secretary screen this correspondence, but we may change this policy if directed by our board of directors due to the nature or volume of the correspondence.

          Communications that are intended specifically for the lead independent director should be sent to the street address noted above, to the attention of the Lead Independent Director.

PROPOSAL TWO

          The audit committee of our board of directors has selected the independent registered public accounting firm of PricewaterhouseCoopers LLP to audit our consolidated financial statements for the fiscal year ending December 31, 2010 and recommends that stockholders vote for ratification of such appointment. Notwithstanding the selection and ratification, the audit committee, in its discretion, may appoint a different independent registered public accounting firm at any time, if it believes doing so would be in our best interests and the best interests of our stockholders. In the event of a negative vote on ratification, the audit committee will reconsider, but might not change, its selection.

          PricewaterhouseCoopers LLP has audited our financial statements annually since 2002. Representatives of PricewaterhouseCoopers LLP are expected to be present at the meeting with the opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions.

Vote required

          Approval of the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm requires the affirmative vote of the holders of at least a majority of the outstanding shares of our common stock entitled to vote and present or represented at the meeting. A properly executed proxy marked “ABSTAIN” with respect to this matter is considered entitled to vote and thus, will have the effect of a vote against a matter.

          In accordance with Delaware law, abstentions will be counted for purposes of determining both whether a quorum is present at the meeting and the total number of shares represented and voting on this proposal. While broker non-votes will be counted for purposes of determining the presence or absence of a quorum, broker non-votes will not be counted for purposes of determining the number of shares represented and voting with respect to the particular proposal on which the broker has expressly not voted and, accordingly, will not affect the approval of this proposal.

The board of directors unanimously recommends that stockholders vote “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2010.

Summary of fees

          The audit committee has adopted a policy for the pre-approval of all audit and permitted non-audit services that may be performed by our independent registered public accounting firm. Under this policy, each year, at the time it engages the independent registered public accounting firm, the audit committee pre-approves the audit engagement terms and fees and may also pre-approve detailed types of audit-related and permitted tax services, subject to certain dollar limits, to be performed during the year. All other permitted non-audit services are required to be pre-approved by the audit committee on an engagement-by-engagement basis.

          The following table summarizes the aggregate fees billed for professional services rendered to us by PricewaterhouseCoopers LLP in 2009 and 2008. A description of these various fees and services follows the table.

		2009				2008
Audit fees		$	445,500			$	567,848
Tax fees			24,508				35,000
Total fees		$	470,008			$	602,848

     Audit fees

          The aggregate fees billed to us by PricewaterhouseCoopers LLP in connection with the annual audit of our financial statements, for the reviews of our financial statements included in the quarterly reports on Form 10-Q, consents related to documents filed with the SEC and accounting and financial reporting consultations and research necessary to comply with generally accepted audit standards, were $445,500 and $567,848 for the years ended December 31, 2009 and 2008, respectively.

     Tax Fees

          The aggregate fees billed to us by PricewaterhouseCoopers LLP in connection with tax services were $24,508 and $35,000 for the years ended December 31, 2009 and 2008, respectively. Tax fees are fees for tax compliance, tax advice and tax planning.

          The audit committee is authorized by its charter to pre-approve all auditing and permitted non-audit services to be performed by our independent registered public accounting firm. The audit committee reviews and approves the independent registered public accounting firm’s retention to perform attest services, including the associated fees. The audit committee also evaluates other known potential engagements of the independent registered public accounting firm, including the scope of the proposed work and the proposed fees, and approves or rejects each service, taking into account whether the services are permissible under applicable law and the possible impact of each non-audit service on the independent registered public accounting firm’s independence from management. At subsequent meetings, the Committee will receive updates on the services actually provided by the independent registered public accounting firm, and management may present additional services for approval. The Committee has delegated to the chairman of the audit committee the authority to evaluate and approve engagements on behalf of the Committee in the event that a need arises for pre-approval between Committee meetings. If the Chairman so approves any such engagements, he will report that approval to the full audit committee at its next meeting. During fiscal 2009, all such services were pre-approved in accordance with the procedures described above.

          Our audit committee has reviewed the fees described above and believes that such fees are compatible with maintaining the independence of PricewaterhouseCoopers LLP.

          Stockholder ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm is not required by our bylaws or other applicable legal requirement. However, the appointment of PricewaterhouseCoopers LLP is being submitted to the stockholders for ratification. If the stockholders fail to ratify the appointment, the audit committee will reconsider whether or not to retain the firm. Even if the appointment is ratified, the audit committee at its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be appropriate.

Pursuant to its charter, our audit committee must then approve any related party transactions, including those transactions involving our directors. In approving or rejecting such proposed transactions, the audit committee considers the relevant facts and circumstances available and deemed relevant to the audit committee, including the material terms of the transactions, risks, benefits, costs, availability of other comparable services or products and, if applicable, the impact on a director’s independence.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

          Section 16(a) of the Exchange Act, requires our directors and executive officers, among others, to file with the SEC and the NYSE an initial report of ownership of our common stock on a Form 3 and reports of changes in ownership on a Form 4 or a Form 5. Persons subject to Section 16 are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file related to transactions in our common stock. Under SEC rules, certain forms of indirect ownership and ownership of our common stock by certain family members are covered by these reporting requirements. As a matter of practice, our administrative staff assists our directors and executive officers in preparing initial ownership reports and reporting ownership changes and typically files these reports on their behalf.

          Based on a review of the copies of such forms in our possession, and on written representations from reporting persons, we believe that during 2009, all of our executive officers and directors filed the required reports on a timely basis under Section 16(a), except a late Form 4 report was filed by Andres Reiner on January 5, 2009 to report the sale of shares in 2008 pursuant to a Rule 10b5-1 plan; a late Form 4 report was filed by Albert Winemiller and Charles Murphy on May 18, 2009 to report the grant of restricted stock units by PROS Holdings Inc.; a late Form 4 report was filed by Jeff Robinson on June 11, 2009 to report the sale of shares pursuant to a Rule 10b5-1 plan; and a late Form 4 report was filed by William Russell on December 3, 2009 to report the vesting of restricted stock units granted by PROS Holdings Inc.

COMPENSATION DISCUSSION AND ANALYSIS

          The following discussion and analysis of compensation arrangements of our named executive officers should be read together with the compensation tables and related disclosures set forth below.

          The goals of our executive compensation program are to:

	•		attract, motivate and retain talented and experienced executives in the pricing and revenue software market;
	•		align the interests of our executive officers and stockholders by motivating executive officers to improve company performance and increase stockholder value;
	•		compensate our executives to manage our business to meet our long-term objectives.

          The responsibility for establishing, administering and interpreting our policies governing the compensation and benefits for our executive officers lies with our compensation committee, which consists entirely of non-employee directors. Our compensation committee has taken the following steps to ensure that our executive compensation and benefit policies are consistent with both our compensation philosophy and our corporate governance guidelines:

	•		evaluated our executive compensation practices and assisted in developing and implementing the executive compensation programs;
	•		established a practice, in accordance with the rules of the NYSE, of reviewing the performance and determining the compensation earned, paid or awarded to our chief executive officer independent of input from him; and
	•		established a policy, in accordance with the rules of the NYSE, to review on an annual basis the performance of our other executive officers with assistance from our chief executive officer and determining what we believe to be appropriate total compensation for these executive officers.

          In 2008 and 2009, our compensation committee did not rely on any benchmark studies of comparable companies in establishing executive compensation. Rather, the compensation committee relied upon the experience and expertise of management and the members of our compensation committee to adopt executive compensation programs. The compensation committee has engaged an independent executive compensation firm to assist in providing guidance on future executive compensation matters.

          Our compensation committee typically invites our chief executive officer and chief financial officer to attend meetings of the compensation committee. During deliberations of compensation decisions relating to our executive officers, the compensation committee considers the recommendations of our chief executive officer and chief financial officer. The compensation committee then separately deliberates and makes determinations about executive compensation, for persons other than the chief executive officer, in executive session. The chief executive officer is typically present during some portion of these deliberations.

          For compensation decisions regarding our chief executive officer and chief financial officer, our compensation committee discusses with the chief executive officer his current compensation and his perspective on his compensation for the upcoming year. The compensation committee then deliberates and determines the compensation of the chief executive officer in executive session outside of the presence of any executive officer, including our chief executive officer. The compensation committee then communicates its decision on his compensation to him through the whole compensation committee or the chairman of the compensation committee.

          The compensation committee takes into consideration general economic and market conditions, our financial condition and operating results, our operating plan, our geographic location and the objectives of our executive compensation policies described below. In 2009, our compensation committee did not prescribe individualized objectives or performance criteria by which to evaluate the executive officers’ performance or contribution to specific items of corporate performance. The compensation committee considered the executive officers’ individual performances in 2008 and earlier years as representative of their continuing ability to perform the functions and to fulfill the responsibilities of their respective positions.

          Our compensation committee establishes executive compensation programs that the compensation committee believes, based on the members’ experience, is the most appropriate to achieve the goals described above. Our compensation committee will continue to evaluate our executive compensation programs on a quantitative and qualitative basis on at least a yearly basis or as circumstances dictate. Our compensation committee expects to make new awards and adjustments to our executive compensation programs on an annual basis.

          Our named executive officers include our principal executive officer, principal financial officer and two other executive officers who earned or were paid in excess of $100,000 during 2009. Although Mr. Robinson is no longer an executive officer for the purposes of Item 402 of Regulation S-K as of October 1, 2009, he is included in the executive compensation analysis as if he were an executive officer as of December 31, 2009.

     Components of executive compensation

       Base salaries

          We use base salaries primarily to retain our executives. Base salaries for our executive officers are reviewed on a yearly basis. In February 2009, the compensation committee reviewed the responsibilities and performance of Messrs. Winemiller, Murphy, Woestemeyer and Reiner, their tenure with us, their existing compensation packages and their expected contributions and responsibilities for 2009. Based on this review, the current global economic challenges and our actions to more closely manage its expenses, the compensation committee elected not to increase the base salaries of the named executive officers for 2009. Messrs. Winemiller, Murphy, Woestemeyer and Reiner base salaries for 2009 were $340,000, $300,000, $233,750 and $210,000, respectively. On July 6, 2009, the board of directors promoted Mr. Reiner, to the position of executive vice president. In connection with such appointment, the compensation committee reviewed Mr. Reiner’s existing compensation package and expected contributions and responsibilities. Based on that review, the compensation committee approved an increase in the base salary of Mr. Reiner from $210,000 to $250,000 for the year 2009.

       Cash incentive

          We have a cash incentive plan for our executive officers under which cash incentive payments may be made after the end of each year based on our performance against our corporate objectives for the year. These cash incentive payments are intended to compensate our executive officers for achievement of our corporate financial goals. The cash incentive payments are generally paid in the first quarter following completion of a given year. Our compensation committee does not have the discretion to increase the targets or decrease the amounts payable to any of our executives, but it does have the discretion to lower the targets and increase the amounts payable under this cash incentive plan. Traditionally, the committee has not exercised this discretion nor did it do so in 2009.

          Each component of this cash incentive plan is independent of the other components and has minimum target and maximum target levels. The target incentive payment amounts are payable under this cash incentive plan if we hit our target levels for each component. Actual results between the minimum, target and the maximum goal levels would be pro-rated. We use our cash incentive plan to align our executive’s performance with our financial results and to motivate our executives to achieve annual goals.

          2009 Cash Incentive Plan. In February 2009, our compensation committee approved our Named Executive Officer Plan (“2009 NEO Plan”) cash incentive plan. The 2009 NEO Plan set target incentive payment amounts based upon three components: (i) revenue, (ii) non-generally accepted accounting principles, or non-GAAP, operating income, and (iii) discretionary. Each of the components is independent of the others, but the weighting of the components as they relate to potential incentive payments is set forth in the following table:

		Weighting of component
Component		as a % of bonus payment
Revenue			45.0	%
Non –GAAP operating income (1)			45.0	%
Discretionary			10.0	%

          The compensation committee felt that increasing the weighting of the revenue and non-GAAP operating income components of the 2009 NEO Plan would heighten management’s focus on maximizing our revenues and profitability during the 2009 fiscal year.

          To align with the Company’s reporting standards, the revenue and non-GAAP operating income components of the 2009 NEO Plan were set on a quarterly basis by the compensation committee and those components were measured at the end of each quarterly period against actual financial results. There is a cumulative annual performance calculation for those two components. The discretionary component was determined by the compensation committee on an annual basis at the end of the Company’s fiscal year. The maximum for the discretionary component was 20%. The payments were made in 2010.

          The potential payouts under the 2009 NEO Plan were based on our performance as a company within a range of each component’s target. No incentive payment was to be earned below the target threshold and the maximum bonus was to be earned at the target maximum. The ranges for each component are set forth in the following table:

		Target minimum				Target maximum
Component		(in millions)				(in millions)
Revenue		$	67.2			$	70.4
Non-GAAP operating income			9.9				12.1

          The following table sets forth our revenue and non-GAAP operating income targets for 2009:

Component (In millions)		Target
Revenue		$	69.0
Non-GAAP operating income			11.7

          The compensation committee set the amount of each incentive payment as a percentage of the base salary of each executive officer as set forth in the following table:

		At target								At target
Executive officer		threshold				At target				maximum
Albert E. Winemiller			50	%			100	%			150	%
Charles H. Murphy			40	%			80	%			120	%
Ronald F. Woestemeyer			22.5	%			45	%			67.5	%
Andres D. Reiner (1)			30	%			60	%			90	%

          Under the 2009 NEO Plan, each executive officer, except Mr. Reiner, achieved 115% of the target payout as presented above. Mr. Reiner achieved 120% of the target payout as presented above.

          Executive compensation activities in 2010. The Named Executive Officer Plan for 2010 sets target bonus amounts and performance criteria for participants. The performance criteria, the criteria’s weighting and the general terms of the Named Executive Officer Bonus Plan for 2010 are consistent with the Company’s 2009 NEO Plan as described above, except that the performance targets under the Named Executive Officer Bonus Plan for 2010 is measured at the end of each six month period.

     Long-term incentive award programs

          Our base salary and cash incentive plan are intended to compensate and motivate for the short-term. Our compensation committee believes that our executive officers’ participating in our equity incentive plans will encourage long-term performance and help to further align their interests with those of our stockholders. In the past, our compensation committee has granted stock options and restricted stock units.

          The Company provides equity awards under its 2007 equity incentive plan. Under the 2007 equity incentive plan, the company may provide incentives through the grant of: (i) restricted stock awards; (ii) restricted stock unit awards; (iii) stock options; (iv) stock appreciation rights; (v) phantom stock; and (vii) performance awards. As of December 31, 2009, there has not been any issuance of restricted stock awards, stock appreciation rights, phantom stock or performance awards under the 2007 equity incentive plan. The Company does not apply mandatory holding periods with respect to stock acquired upon exercise of stock options or vesting of restricted stock units.

          The compensation committee believes that the use of equity awards offers the best approach to achieve our compensation goals with respect to long-term incentives and currently provides tax and other advantages to our executive officers relative to other forms of equity compensation. As of December 31, 2009, we have granted stock options and restricted stock units since we believe that these types of equity awards are competitive in our industry and are best understood by our executive officers.

          In 2009, the compensation committee determined the size of annual awards based upon the committee’s subjective assessment of the incentive value of the executive officers’ respective total equity interests relative to their roles in the company and their levels of vested and unvested shares. We believe that our equity incentive program is an important retention tool for our executive officers.

          During 2009, the compensation committee conducted an annual review of the compensation packages of our executive officers, including the retention value of their compensation components, their contributions to our business and their ability to continue to provide leadership to us and to maintain our success. The compensation committee believed it was in our best interests to provide additional equity awards to our executive officers to incentivize them and to provide additional retention value. In May 2009, we granted to each of our chief executive officer and chief financial officer 150,000 restricted stock units. In addition, we granted Mr. Reiner 25,000 restricted stock units in March 2009. Mr. Woestemeyer was not granted any stock options at this time because the compensation committee believed that his significant equity ownership was sufficient for motivation and retention.

          Security Ownership Guidelines. All executive officers are required to hold at least $100,000 worth of the Company’s stock, and/or the units issued as compensation for service, while serving as an executive officer of the Company. New executive officers will have five years to attain this ownership threshold. Shares, units or unexercised options held by an executive officer under any of the Company’s equity incentive plans are included in calculating the value of ownership to determine whether this minimum ownership requirement has been met.

          1999 equity incentive plan. Our 1999 equity incentive plan (“1999 plan”) authorized us to grant options to purchase shares of common stock to our employees, directors and consultants at our discretion. Our 1999 plan was terminated in March 2007 for purposes of granting any future equity awards. There were issued and outstanding stock options to purchase 99,610 shares of our common stock under this plan on December 31, 2009. None of these options were held by executive officers.

          2007 equity incentive plan. Our 2007 equity incentive plan (“2007 plan”) was adopted in March 2007. The purpose of the 2007 plan is to promote our long-term growth and profitability. The 2007 plan is intended to make available incentives that will help us to attract, retain and reward employees whose contributions are essential to our success. Under the 2007 plan, our employees, officers, directors and other individuals providing services to us or any our affiliates are eligible to receive awards. The 2007 plan has an evergreen provision that allows for an annual increase equal to the lesser of (i) 3.5% of our outstanding shares (ii) 900,000 shares or (iii) any lesser amount determined by the compensation committee of the board of directors. We may provide these incentives through the grant of: (i) restricted stock awards; (ii) restricted stock unit awards; (iii) stock options; (iv) stock appreciation rights; (v) phantom stock; and (vii) performance awards.

          In February 2009, we increased the number of shares available to grant by 898,000 under the evergreen provision in our 2007 plan increasing the number shares reserved for issuance to 3,668,000. On March 9, 2010, we further increased the number of shares available by 900,000 under the evergreen provision in our 2007 equity incentive plan increasing the number of shares reserved for issuance to 4,568,000. As of December 31, 2009, we had outstanding equity awards to acquire 3,587,917 shares of its common stock held by our employees, directors and consultants under the 2007 plan. Included in such outstanding equity awards is 1,331,500 restricted stock units held by our employees, directors and consultants. As of December 31, 2009, 35,857 shares remained available for grant under the 2007 plan. As of December 31, 2009, there has not been any issuance of restricted stock awards, stock appreciation rights, phantom stock or performance awards under this plan.

          Stock options generally have a ten-year term and typically vest over three to four years of which 99,610 are related to the 1999 equity incentive plan and 2,256,417 are related to the 2007 plan. In addition, there are 1,331,500 restricted stock units outstanding under the 2007 plan.

          Stock options. Our 2007 plan permits the granting of options to purchase shares of our common stock intended to qualify as incentive stock options, under Section 422 of the Internal Revenue Code, and nonqualified stock options. The option exercise price and the term of each option are determined by the compensation committee. The compensation committee also determines at what time or times each option may be exercised and the period of time, if any, after retirement, death, disability or termination of employment during which options may be exercised. The compensation committee, as plan administrator, can determine vesting for grants which generally expire ten years after the date of the grant.

          Stock appreciation rights. The compensation committee may grant a right to receive a number of shares or, in the discretion of the compensation committee, an amount in cash or a combination of shares and cash, based on the increase in the fair market value of the shares underlying the right during a stated period specified by the compensation committee.

          Restricted stock awards and units. The compensation committee may award shares of our common stock to participants at no cost or for a purchase price or restricted stock units that are settled in shares of our common stock. These restricted stock and restricted stock unit awards may be subject to restrictions or may be free from any restrictions under our 2007 plan. The purchase price of the shares, if any, and any applicable restrictions, are determined by the compensation committee.

          Phantom stock. The compensation committee may grant stock equivalent rights, or phantom stock, which entitles the recipient to receive credits which are ultimately payable in the form of cash, shares of our common stock or a combination of both. Phantom stock does not entitle the holder to any rights as a stockholder.

          Performance awards. The compensation committee may grant performance awards to participants entitling the participants to receive cash, shares of our common stock or a combination of both, upon the achievement of performance goals and other conditions determined by the compensation committee. The performance goals may be based on our operating income or on one or more other business criteria selected by the compensation committee.

          In the event of any stock split, stock dividend or similar transaction, the shares subject to the 2007 plan and any outstanding awards will automatically be adjusted. The 2007 plan will continue in effect until the tenth anniversary of its approval by our board, unless earlier terminated earlier. The compensation committee may amend, terminate or modify the plan at any time.

          In the event of certain significant corporate transactions, including a change in control of the Company, any then-outstanding equity award or option under the 2007 plan may be assumed, continued or substituted for by any surviving or acquiring entity (or its parent company). If the surviving or acquiring entity (or its parent company) elects to assume, continue or substitute for such awards or options and the holder of such award or option is terminated without cause or resigns for “good reason” within 18 months of a change of control of the Company, such awards or options shall vest in full. If the surviving or acquiring entity (or its parent company) elects not to assume, continue or substitute for the equity awards or options under the 2007 plan, all outstanding equity awards and options under the 2007 plan will vest in full and become fully exercisable.

          Benefits. We provide our executive officers the following benefits, generally on the same terms as we provide our other employees.

          health, dental, travel, accident insurance and vision;

          life insurance;

          employee assistance plan;

          medical and dependent care flexible spending account;

          short-and long-term disability, accidental death and dismemberment;

          a 401(k) plan;

          paid time off and vacations;

          sick days; and

          tuition reimbursement.

          We believe these benefits are consistent with companies with which we compete for employees.

          401(k) Plan. In May 1996, we adopted a tax-qualified employee savings and retirement plan, or 401(k) plan, which generally covers our full-time employees. The plan is intended to qualify under Section 401(a) of the Internal Revenue Code. Contributions, and income earned thereon, are not taxable to employees until withdrawn from this plan. Under this plan, employees may elect to reduce their current compensation up to the statutorily prescribed annual limit and have the amount of the reduction contributed to the plan. This plan also permits us to make matching contributions to the plan on behalf of participants. Historically, the Company’s matching contribution is defined as 50% of the first 6% of employee contributions. The Company may also make discretionary contributions. The Company temporarily discontinued the matching contribution in 2009 as a result the economic conditions during 2009. The Company is planning to reinstate the 401(k) matching contribution in the future upon achievement of certain performance targets.

     Severance and termination provisions

          We provide our executive officers severance packages if they are terminated without cause (as defined in their employment or severance agreements) in order to attract and retain them. The amount of severance benefits is described below. The compensation committee reviews the potential payouts to ensure their market-competitiveness in order to incentivize our executive officers to maintain focus on both daily and long-term efforts.

          On March 24, 2009, the Company entered into a First Amendment of Employment Agreement with Mr. Reiner. The First Amendment of Employment Agreement with Mr. Reiner would provide for payment of (i) any unpaid bonus earned prior to the termination relating to completed bonus periods preceding the date of termination, and (ii) the payment of a bonus at one hundred percent of performance targets, including discretionary components, within the bonus plan in effect as if employed by the Company for twelve months. The unpaid bonus described in subsection (i) shall be paid on or about termination and the bonus as described in subsection (ii) shall be payable in equal installments during the twelve month period following termination. Such bonuses are payable if Mr. Reiner is terminated by us without cause, as defined in the agreement or by Mr. Reiner for “good reason,” as defined in the agreement.

          On March 24, 2009, the Company entered into a Second Amendment of Employment Agreement with Messrs. Winemiller and Murphy. The Second Amendment of Employment Agreement will provide Messrs. Winemiller and Murphy with payment of (i) any unpaid bonus earned prior to the termination relating to completed bonus periods preceding the date of termination, and (ii) the payment of a bonus at one hundred percent of performance targets, including discretionary components, within the bonus plan in effect as if employed by the Company for twelve months. The unpaid bonus described in subsection (i) shall be paid on or about termination and the bonus as described in subsection (ii) shall be payable in equal installments during the twelve month period following termination. Such bonuses are payable if Messrs. Winemiller and Murphy are terminated by us without cause, as defined in the agreement or by Mr. Winemiller or Mr. Murphy, as applicable, for “good reason,” as defined in the agreement. In addition, the amended employment agreements provides for the payment of (i) any unpaid bonus earned prior to the termination relating to completed bonus periods preceding the date of termination, and (ii) the payment of a bonus at one hundred percent of performance targets, including discretionary components, within the bonus plan in effect as if employed by the Company for eighteen months if such officer is terminated without cause or if such officer resigns for “good reason” within six months prior to or any time after a change in control transaction of the Company. Messrs. Winemiller and Murphy are subject to non-competition and non-solicitation restrictions during the term of their employment and for the 12-month period following the termination of their employment.

          We entered into employment agreement with Mr. Reiner, our current executive vice president, on April 24, 2008. This agreement is for a two-year term and automatically renews for one-year terms unless the Company decides not to renew. The base salary payable to Mr. Reiner is subject to periodic review by our compensation committee. Mr. Reiner is entitled to 12 months of severance, up to 12 months of health benefits and acceleration of the vesting of his stock options or other equity awards with respect to shares comprising fifty percent of the unvested shares under such stock options or other equity awards as of the date of termination. Mr. Reiner is subject to non-competition and non-solicitation restrictions during the term of his employment and for the 12-month period following the termination of his employment.

          We entered into employment agreements with Mr. Winemiller, our chief executive officer, and Mr. Murphy, our chief financial officer, on September 30, 2005. Both of these agreements were originally for a two- year term and automatically renew for one-year terms unless the Company decides not to renew them. The base salaries payable to each of Messrs. Winemiller and Murphy are subject to periodic review by our compensation committee. Both Messrs. Winemiller and Murphy are entitled to 12 months of severance, up to 12 months of health benefits and 12 months of acceleration of the vesting on their stock options granted prior to April 2, 2007 if their employment with us is terminated without cause or they resign with “good reason,” as defined in those agreements. On April 2, 2007, our board amended these employment agreements to also provide for the full acceleration of vesting, or lapse of all repurchase rights, of any options or other equity awards granted to these executive officers on or after April 2, 2007, if any of these officers is terminated without “cause,” resigns for “good reason” or if a change of control of the Company occurs. In addition, the amended employment agreements provide for 18 months of severance and 18 months of health benefits if such officer is terminated without cause or if such officer resigns for “good reason” within six months prior to or any time after a change in control transaction of the Company. Messrs. Winemiller and Murphy are subject to non-competition and non-solicitation restrictions during the term of their employment and for the 12-month period following the termination of their employment.

          In January 1999, we entered into an employment agreement with Mr. Woestemeyer, our executive vice president. This agreement was originally for a two-year term and automatically renews for one-year terms unless the Company decides not to renew. Under this agreement, Mr. Woestemeyer’s salary is subject to periodic review by our compensation committee, and he is entitled to 12 months of severance if he is terminated without cause as defined in his agreement or we decide not to renew his agreement without giving him notice. If we decide not to renew this agreement and we provide 60-days notice of non-renewal to Mr. Woestemeyer, he is entitled to 10 months of severance. In addition, Mr. Woestemeyer is subject to non-competition and non-solicitation restrictions during the term of his employment and for the severance period following the termination of his employment.

          Cause is defined in these employment agreements as a breach by our officer of his duties of confidentiality which causes a material harm to us, his conviction of, or a plea of guilty or no contest to, a felony or his failure to perform his duties after notice and a cure period. In addition, for Messrs. Winemiller, Murphy and Reiner, cause also includes an intentional wrongdoing by them that adversely affects us. Messrs. Winemiller, Murphy and Reiner can resign for “good reason” and be entitled to severance. “Good reason” is defined in their employment agreements as the assignment of duties to them that are substantially inconsistent with their current roles with us, the relocation of their offices to more than 50 miles from our present location, a material reduction in their base salaries and our failure to provide them with similar benefits that we provide to our other employees.

     Tax considerations

          We are subject to Internal Revenue Code Section 162(m), which limits the amount that we may deduct for compensation paid to our chief executive officer and to each of our four most highly compensated officers to $1,000,000 per person per year, unless certain exemption requirements are met. Exemptions to this deductibility limit may be made for various forms of “performance-based” compensation approved by our stockholders. In addition to salary and bonus compensation that is not “performance-based,” the exercise of stock options may cause an officer’s total compensation to exceed $1,000,000. However, compensation from options that meet certain requirements will be exempt from the $1,000,000 cap on deductibility. In the past, annual cash compensation to our executive officers has not exceeded $1,000,000 per person. Although we do not currently anticipate such compensation to exceed the $1,000,000 limit, our officer compensation could in the future exceed this limit, and we may not be able to deduct the compensation amount in excess of $1,000,000. While the compensation committee cannot predict how the deductibility limit may impact our compensation program in future years, the compensation committee intends to maintain an approach to executive compensation that strongly links pay to performance.

COMPENSATION COMMITTEE REPORT

          The compensation committee has reviewed and discussed the preceding Compensation Discussion and Analysis section of this proxy statement with our management. Based on this review and discussion, the compensation committee recommended to our board of directors that the Compensation Discussion and Analysis be included in our proxy statement and incorporated by reference into our Annual Report on Form 10-K for the year ended December 31, 2009.
