ABOUT THE MEETING

What is a proxy?

     A proxy is your legal designation of another person to vote the stock you own on your behalf. That other person is referred to as a “proxy.” Our Board of Directors has designated Robert P. Peebler and James M. Lapeyre, Jr. as proxies for the 2009 Annual Meeting of Stockholders. By completing and returning the enclosed proxy card, you are giving Mr. Peebler and Mr. Lapeyre the authority to vote your shares in the manner you indicate on your proxy card.

Who is soliciting my proxy?

     Our Board of Directors is soliciting proxies on its behalf to be voted at the 2009 Annual Meeting. All costs of soliciting the proxies will be paid by ION. Copies of solicitation materials will be furnished to banks, brokers, nominees and other fiduciaries and custodians to forward to beneficial owners of ION’s common stock held by such persons. ION will reimburse such persons for their reasonable out-of-pocket expenses in forwarding solicitation materials. In addition to solicitations by mail, some of ION’s directors, officers and other employees, without extra compensation, might supplement this solicitation by telephone, personal interview or other communication. ION has also retained Georgeson Inc. to assist with the solicitation of proxies from banks, brokers, nominees and other holders, for a fixed fee of $8,000 plus reasonable out-of-pocket expenses, which fees and expenses will be paid by ION. We may also ask our proxy solicitor to solicit proxies on our behalf by telephone for a fixed fee of $5 per phone call and $5 per telephone vote, plus reasonable expenses.

What is a proxy statement?

     A proxy statement is a document that the regulations of the Securities and Exchange Commission require us to give you when we ask you to sign a proxy card designating individuals as proxies to vote on your behalf.

What is the difference between a “stockholder of record” and a stockholder who holds stock in “street name”?

     If your shares are registered directly in your name, you are a stockholder of record. If your shares are registered in the name of your broker or bank, you are a street name holder.

What different methods can I use to vote?

     Most stockholders have a choice of voting over the Internet, by telephone, or by using a traditional proxy card. Please check your proxy card or the information forwarded by your bank, broker or other holder of record to see which options are available to you.

     (a) In Writing: All stockholders can vote by written proxy card.

     (b) By Telephone and Internet: Street name holders may vote by telephone or the Internet if their bank or broker makes those methods available, in which case the bank or broker will enclose the instructions with the proxy statement. The telephone and Internet voting procedures, including the use of control numbers, are designed to authenticate stockholders’ identities, to allow stockholders to vote their shares, and to confirm that their instructions have been properly recorded.

     (c) In Person: All stockholders may vote in person at the meeting. If you are a street name holder who wishes to vote in person, you will need to ask your broker or bank for a legal proxy. You will need to bring the legal proxy with you to the meeting.

Where will the Annual Meeting be held?

     ION’s 2009 Annual Meeting of Stockholders will be held on the 9^th Floor of 2105 CityWest Boulevard in Houston, Texas.

     Directions: The site for the meeting is located on CityWest Boulevard off of Beltway 8, near the intersection of Beltway 8 and Briar Forest Drive. Traveling south on the Beltway 8 feeder road after Briar Forest Drive, turn right on Del Monte Drive. Enter Garage Entrance 3 on your immediate left. Advise the guard that you are attending the ION Annual Meeting. You may be required to show your driver’s license or other photo identification. The guard will then direct you where to park in the visitors section of the parking garage. The guard can also direct you to 2105 CityWest Boulevard, which is directly south of the garage. Once in the building, check in with the security desk and then take the elevators to the 9^th floor.

Does my vote matter?

     Yes! Corporations are required to obtain stockholder approval for the election of directors and other important matters. Stockholder participation is not a mere formality. Stockholder voting is essential for ION to continue to function. It is also important that you vote to assure that a quorum is obtained so that corporate business can be transacted at the meeting.

What is the effect of not voting?

     It depends on how ownership of your shares is registered. If you are a stockholder of record, your unvoted shares will not be represented at the meeting and will not count toward the quorum requirement. Assuming a quorum is obtained, your unvoted shares will not be treated as a vote for or against a proposal.

     If you own your shares in street name, your broker or bank may represent your shares at the meeting for purposes of obtaining a quorum. As described in the answer to the question immediately following, in the absence of your voting instruction, your broker may or may not vote your shares.

If I don’t vote, will my broker vote for me?

     If you own your shares in street name and you do not vote, your broker may vote your shares in its discretion on “routine matters.” With respect to non-routine matters, however, your broker may not vote your shares for you. Where a broker votes your shares on routine matters but cannot vote your shares on non-routine matters because he has not received any instructions from you regarding how to vote, the number of unvoted shares on those matters is reported as “broker non-votes.” These “broker non-vote” shares are counted toward the quorum requirement, but, generally speaking, they do not affect the determination of whether a matter is approved. See “—How are abstentions and broker non-votes counted?” below. Except for the proposal to approve the Replenishment Program and the proposal to approve the Reverse Stock Split, we believe that the proposals set forth in this proxy statement are routine matters on which brokers will be permitted to vote your shares without instructions from you.

What is the record date and what does it mean?

     The record date for the 2009 Annual Meeting of Stockholders is April 2, 2009. The record date is established by the Board of Directors as required by Delaware law (the state in which we are incorporated). Owners of common stock at the close of business on the record date are entitled to receive notice of the meeting and vote at the meeting and any adjournments or postponements of the meeting.

How can I revoke a proxy?

     A stockholder can revoke a proxy by taking any one of the following three actions before it is voted at the meeting:

     (a) giving written notice to the Corporate Secretary of ION,

     (b) delivering a later-dated proxy, or

     (c) voting in person at the meeting.

     If you hold shares through a bank or broker, you must contact that bank or broker in order to revoke any prior voting instructions.

What constitutes a quorum?

     The presence, in person or by proxy, of the holders of a majority of the outstanding shares of common stock constitutes a quorum. We need a quorum of stockholders to hold a valid Annual Meeting. If you have signed and returned your proxy card, your shares will be counted toward the quorum. If a quorum is not present, the chairman may adjourn the meeting, without notice other than by announcement at the meeting, until the required quorum is present.

     As of the record date, 100,600,792 shares of common stock were outstanding. Thus, the presence of the holders of common stock representing at least 50,300,397 shares will be required to establish a quorum.

What are my voting choices when voting for director nominees, and what vote is needed to elect directors?

     In voting on the election of three director nominees to serve until the 2012 Annual Meeting of Stockholders, stockholders may vote in one of the following ways:

     (a) in favor of all nominees,

     (b) withhold votes as to all nominees, or

     (c) withhold votes as to a specific nominee.

     Directors will be elected by a plurality vote of holders of the shares of common stock present or represented by proxy at the meeting. This means that all director nominees must receive the highest number of votes cast in order to be re-elected as directors. Stockholders are not permitted to cumulate their votes in the election of directors.

     The Board recommends a vote “FOR” all of the nominees.

What are my voting choices when voting on the proposal to approve the Replenishment Program and what vote is needed to approve the proposal?

     In voting to approve the Replenishment Program, stockholders may vote in one of the following ways:

     (a) in favor of the approval of the Replenishment Program,

     (b) against the approval of the Replenishment Program, or

     (c) abstain from voting on the approval of the Replenishment Program.

     The proposal to approve the Replenishment Program will require the affirmative vote of a majority of the votes cast on the proposal by holders of common stock in person or represented by proxy at the meeting, so long as the total votes cast on the proposal exceed 50% of the shares of common stock outstanding.

     The Board recommends a vote “FOR” this proposal.

What are my voting choices when voting on the proposal to approve the Reverse Stock Split and what vote is needed to approve the proposal?

     In voting to approve the Reverse Stock Split proposal, stockholders may vote in one of the following ways:

     (a) in favor of the Reverse Stock Split proposal,

     (b) against the Reverse Stock Split proposal, or

     (c) abstain from voting on the Reverse Stock Split proposal.

     The proposal to approve the Reverse Stock Split will require the affirmative vote of holders of a majority of the shares of common stock outstanding as of the record date.

     The Board recommends a vote “FOR” this proposal.

What are my voting choices when voting on the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm — or independent auditors — and what vote is needed to ratify their appointment?

     In voting to ratify the appointment of Ernst & Young LLP as independent auditors for 2009, stockholders may vote in one of the following ways:

     (a) in favor of ratification,

     (b) against ratification, or

     (c) abstain from voting on ratification.

     The proposal to ratify the appointment of Ernst & Young LLP will require the affirmative vote of a majority of the votes cast by holders of common stock in person or represented by proxy at the meeting.

     The Board recommends a vote “FOR” this proposal.

Will any other business be transacted at the meeting? If so, how will my proxy be voted?

     We do not know of any business to be transacted at the Annual Meeting other than those matters described in this proxy statement. We believe that the periods specified in ION’s Bylaws for submitting proposals to be considered at the meeting have passed and no proposals were submitted. However, should any other matters properly come before the meeting, and any adjournments or postponements of the meeting, shares with respect to which voting authority has been granted to the proxies will be voted by the proxies in accordance with their judgment.

What if a stockholder does not specify a choice for a matter when returning a proxy?

     Stockholders should specify their choice for each matter on the enclosed form of proxy. If no instructions are given, proxies that are signed and returned will be voted “FOR” the election of all director nominees, “FOR” the approval of the Replenishment Program, “FOR” the approval of the Reverse Stock Split and “FOR” the proposal to ratify the appointment of Ernst & Young LLP as independent auditors for 2009.

How are abstentions and broker non-votes counted?

     A properly executed proxy card marked “withhold” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, although it will be counted for purposes of determining whether there is a quorum. Any shares not voted (whether by broker non-vote or otherwise) will have no effect on the election of directors.

     An abstention will have the same legal effect as a vote against the proposal to approve the Replenishment Program because it will represent a share present in person or represented by proxy at the meeting and a vote cast on the

proposal, thereby increasing the number of affirmative votes required to approve the proposal. Broker non-votes will have no effect on the outcome of this proposal, so long as the total votes cast on the proposal represent more than 50% of our outstanding shares of common stock entitled to vote.

     An abstention will have the same legal effect as a vote against the Reverse Stock Split proposal because it will not represent an affirmative vote in favor of this proposal. Broker non-votes will have no effect on the outcome of this proposal, since broker non-votes are not counted as a vote cast on the proposal.

     An abstention will have the same legal effect as a vote against the proposal to ratify the appointment of the independent auditors, because it will represent a share present in person or represented by proxy at the meeting and a vote cast on the proposal, thereby increasing the number of affirmative votes required to approve the proposal. Broker non-votes will have no effect on the proposal to ratify the appointment of the independent auditors.

What is the deadline for submitting proposals to be considered for inclusion in the 2010 proxy statement?

     Stockholder proposals requested to be included in ION’s 2010 proxy statement must be received by ION not later than December 24, 2009. Proposals should be directed to David L. Roland, Senior Vice President, General Counsel and Corporate Secretary, ION Geophysical Corporation, 2105 CityWest Boulevard, Suite 400, Houston, Texas 77042-2839.

What is the deadline for submitting a nomination for director of ION for consideration at the Annual Meeting of Stockholders in 2010?

     A proper director nomination may be considered at ION’s 2010 Annual Meeting of Stockholders only if the proposal for nomination is received by ION not later than December 24, 2009. All nominations should be directed to David L. Roland, Senior Vice President, General Counsel and Corporate Secretary, ION Geophysical Corporation, 2105 CityWest Boulevard, Suite 400, Houston, Texas 77042-2839.

Will I have electronic access to the proxy materials and Annual Report?

     The notice of Annual Meeting and Proxy Statement and the 2008 Annual Report to Stockholders are also posted on ION’s Internet website in the Investor Relations section at www.iongeo.com.

How can I obtain a copy of ION’s Annual Report on Form 10-K?

     A copy of our 2008 Annual Report on Form 10-K is enclosed with our annual report to stockholders. You may obtain an additional copy of our 2008 Form 10-K at no charge by sending a written request to David L. Roland, Senior Vice President, General Counsel and Corporate Secretary, ION Geophysical Corporation, 2105 CityWest Boulevard, Suite 400, Houston, Texas 77042-2839. Our Form 10-K is also available (i) through the Investor Relations section of our website at www.iongeo.com and (ii) with exhibits on the SEC’s website at http://www.sec.gov.

ITEM 1—ELECTION OF DIRECTORS

     Our Board of Directors consists of nine members. The Board is divided into three classes. Members of each class are elected for three-year terms and until their respective successors are duly elected and qualified, unless the director dies, resigns, retires, is disqualified or is removed. Our stockholders elect the directors in a designated class annually. Directors in Class I, which is the class of directors to be elected at this meeting, will serve on the Board until our Annual Meeting in 2012.

     The current Class I directors are Theodore H. Elliott, Jr., James M. Lapeyre, Jr. and G. Thomas Marsh, and their terms will expire at the 2009 Annual Meeting. At its meeting on February 13, 2009, the Board approved the recommendation of the Governance Committee that Messrs. Elliott, Lapeyre and Marsh be nominated to stand for

reelection at the Annual Meeting to hold office until our 2012 Annual Meeting and until their successors are elected and qualified.

     We have no reason to believe that any of the nominees will be unable or unwilling to serve if elected. However, if any nominee should become unable or unwilling to serve for any reason, proxies may be voted for another person nominated as a substitute by the Board of Directors, or the Board of Directors may reduce the number of Directors.

     The Board of Directors recommends a vote “FOR” the election of Theodore H. Elliott, Jr., James M. Lapeyre, Jr. and G. Thomas Marsh.

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires directors and certain officers of ION, and persons who own more than 10% of ION’s common stock, to file with the Securities and Exchange Commission (“SEC”) and the New York Stock Exchange (“NYSE”) initial statements of beneficial ownership on Form 3 and changes in such ownership on Forms 4 and 5. Based on our review of the copies of such reports, we believe

that, with one exception, during 2008 our directors, executive officers and stockholders holding greater than 10% of our outstanding shares complied with all applicable filing requirements. A Form 4 for each of Mr. Sam K. Smith (who retired from our Board of Directors in August 2008) and Messrs. Lapeyre, Appelbaum and Myers reflecting a grant of ION stock on May 27, 2008 in lieu of payment of Board retainer fees was filed on July 29, 2008, due to an administrative error.

Board of Directors and Corporate Governance

     Governance Initiatives. We maintain a corporate governance program for the purpose of defining responsibilities, setting standards of professional and personal conduct and promoting compliance with these responsibilities and standards. We review our governance practices and update them, as appropriate, based upon Delaware law, rules and listing standards of the NYSE, SEC regulations, and practices recommended by our outside advisors.

     Some of our corporate governance initiatives include the following:

	•		Our Board has affirmatively determined that eight of our nine directors meet the NYSE standard for independence. Robert P. Peebler is not independent under applicable standards because he is our current Chief Executive Officer and an employee of ION.
	•		Our Audit Committee has at least one member who qualifies as a “financial expert” in accordance with Section 407 of the Sarbanes-Oxley Act of 2002.
	•		All members of our Audit Committee, Governance Committee and Compensation Committee are independent.
	•		Our independent directors meet in executive session at each regularly scheduled Board meeting without the presence of management. Each of our committees meets in executive session at each regularly scheduled meeting without the presence of management, and our Audit Committee meets in private session with representatives of our independent registered public accounting firm at least quarterly without the presence of management.
	•		Every year, our management employees and senior finance and accounting employees affirm their compliance with our Code of Ethics and other principal compliance policies. New employees sign a written certification of compliance with these policies upon commencing employment.
	•		The Board has adopted written Corporate Governance Guidelines to assist its members in fulfilling their responsibilities.
	•		Board members are required to offer their resignation from the Board if they retire or materially change the position they held when they began serving as a director on the Board.
	•		We comply with and operate in a manner consistent with regulations prohibiting loans to our directors and executive officers.
	•		Members of our Disclosure Committee, consisting of management employees and senior finance and accounting employees, review all quarterly and annual reports before filing with the SEC.
	•		We have a hotline and website available to all employees to report ethics and compliance concerns, anonymously if preferred, including concerns related to accounting, accounting controls, financial reporting and auditing matters. The hotline and website are administered and monitored by an independent hotline monitoring company. The Board has adopted a policy and procedures for the receipt, retention and treatment of complaints and employee concerns received through the hotline or website. The policy is available on our website at http://www.iongeo.com/ content/released/Hotline_Policy-ION-Nov_5_2007.pdf.

	•		On an annual basis, each director and named executive officer is obligated to complete a questionnaire that requires disclosure of any transactions with ION in which the director or executive officer, or any member of his or her immediate family, has a direct or indirect material interest.
	•		We have included as Exhibits 31.1 and 31.2 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2008, filed with the SEC, certificates of our Chief Executive Officer and Chief Financial Officer, respectively, certifying as to the quality of our public disclosure. In addition, in 2008, we submitted to the NYSE a certificate of our Chief Executive Officer certifying that he is not aware of any violation by ION of the NYSE corporate governance listing standards.

     Code of Ethics. We require all employees to adhere to our Code of Ethics in addressing legal and ethical issues encountered in conducting their work. The Code of Ethics requires that our employees avoid conflicts of interest, comply with all laws and other legal requirements, conduct business in an honest and ethical manner, promote full and accurate financial reporting, and otherwise act with integrity and in ION’s best interest. Our Code of Ethics applies to our directors and all employees, including our Chief Executive Officer and senior financial officers (our Chief Financial Officer, Controller, Treasurer and all other financial officers and executives).

     We have made our Code of Ethics, corporate governance guidelines, charters for the committees of our Board and other information that may be of interest to investors available on the Investor Relations section of our website at http://www.iongeo.com/Investor_Relations/ Corporate_Governance/. Copies of this information may also be obtained by writing to us at ION Geophysical Corporation, Attention: Senior Vice President, General Counsel and Corporate Secretary, 2105 CityWest Boulevard, Suite 400, Houston, Texas 77042-2839.

     Presiding Non-Management Director. Under NYSE corporate governance listing standards, James M. Lapeyre, Jr. has been designated as the presiding non-management director to lead non-management directors meetings of the Board. Our non-management directors meet at regularly scheduled executive sessions without management, over which Mr. Lapeyre presides.

     Communications to Board and Presiding Non-Management Director. Stockholders and other interested parties may communicate with the Board and our presiding non-management director or non-management independent directors as a group by writing to “Chairman of the Board” (if the intended recipient is the Board) or “Presiding Non-management Director” (if the intended recipient is the presiding non-management director, or the non-management directors as a whole), c/o Corporate Secretary, ION Geophysical Corporation, 2105 CityWest Boulevard, Suite 400, Houston, Texas 77042-2839. Inquiries sent by mail will be reviewed by our Corporate Secretary and, if they pertain to the functions of the Board or Board committees or if the Corporate Secretary otherwise determines that they should be brought to the intended recipient’s attention, they will be forwarded to the intended recipient. Concerns relating to accounting, internal controls, auditing or compliance matters will be brought to the attention of our Audit Committee and handled in accordance with procedures established by the Audit Committee.

     Our Corporate Secretary’s review of these communications will be performed with a view that the integrity of this process be preserved. For example, items that are unrelated to the duties and responsibilities of the Board, such as personal employee complaints, product inquiries, new product suggestions, resumes and other forms of job inquiries, surveys, business solicitations or advertisements, will not be forwarded to those individuals. In addition, material that is considered to be hostile, threatening, illegal or similarly unsuitable will not be forwarded to them. Except for these types of items, the Corporate Secretary will promptly forward written communications to the intended recipient. Within the above guidelines, the independent directors have granted the Corporate Secretary discretion to decide what correspondence should be shared with ION management and independent directors.

     2008 Meetings of the Board and Stockholders. During 2008, the Board of Directors held 14 meetings and the four standing committees of the Board of Directors held a total of 20 meetings. Overall, the rate of attendance by each director at such meetings exceeded 96%. Each director attended at least 75% of the aggregate number of meetings of the Board of Directors and the committees on which he served during 2008. We do not require our Board members to attend our Annual Meeting of Stockholders; however, three of our directors attended our 2008 Annual Meeting held in May 2008.

     Independence. In determining independence, each year the Board determines whether directors have any “material relationship” with ION. When assessing the “materiality” of a director’s relationship with ION, the Board considers all relevant facts and circumstances, not merely from the director’s standpoint, but from that of the persons or organizations with which the director has an affiliation, and the frequency or regularity of the services, whether the services are being carried out at arm’s length in the ordinary course of business and whether the services are being provided substantially on the same terms to ION as those prevailing at the time from unrelated parties for comparable transactions. Material relationships can include commercial, banking, industrial, consulting, legal, accounting, charitable and familial relationships. Factors that the Board may consider when determining independence for purposes of this determination include (1) not being a current employee of ION or having been employed by ION within the last three years; (2) not having an immediate family member who is, or who has been within the last three years, an executive officer of ION; (3) not personally receiving or having an immediate family member who has received, during any 12-month period within the last three years, more than $120,000 per year in direct compensation from ION other than director and committee fees; (4) not being employed or having an immediate family member employed within the last three years as an executive officer of another company of which any current executive officer of ION serves or has served, at the same time, on that company’s compensation committee; (5) not being an employee of or a current partner of, or having an immediate family member who is a current partner of, a firm that is ION’s internal or external auditor; (6) not having an immediate family member who is a current employee of such an audit firm who personally works on ION’s audit; (7) not being or having an immediate family member who was within the last three years a partner or employee of such an audit firm and who personally worked on ION’s audit within that time; (8) not being a current employee, or having an immediate family member who is a current executive officer, of a company that has made payments to, or received payments from, ION for property or services in an amount that, in any of the last three fiscal years, exceeds the greater of $1 million or 2% of the other company’s consolidated gross revenues; or (9) not being an executive officer of a charitable organization to which, within the preceding three years, ION has made charitable contributions in any single fiscal year that has exceeded the greater of $1 million or 2% of such organization’s consolidated gross revenues.

     Our Board has affirmatively determined that none of our non-employee directors — James M. Lapeyre, Jr., Bruce S. Appelbaum, Theodore H. Elliott, Jr., G. Thomas Marsh, Franklin Myers, S. James Nelson, Jr., John N. Seitz and Nicholas G. Vlahakis — has a material relationship with ION within the meaning of the NYSE’s listing standards, and that each of them is independent from management and from our independent registered public accounting firm, as required by NYSE listing standard rules regarding director independence. See “ — Committees of the Board — Audit Committee” below.

     Our Chairman, Mr. Lapeyre, is an executive officer and significant shareholder of Laitram, L.L.C., a company with which ION has ongoing contractual relationships, and Mr. Lapeyre and Laitram together owned approximately 9.4% of our outstanding common stock as of February 20, 2009. Our Board has determined that these contractual relationships have not interfered with Mr. Lapeyre’s demonstrated independence from our management, and that the services performed by Laitram for ION are being provided at arm’s length in the ordinary course of business and substantially on the same terms to ION as those prevailing at the time from unrelated parties for comparable transactions. In addition, the services provided by Laitram to ION resulted in payments by ION to Laitram in an amount less than 2% of Laitram’s 2008 consolidated gross revenues. As a result of these factors, our Board has determined that Mr. Lapeyre, along with each of our other non-management directors, is independent within the meaning of the NYSE’s director independence standards. For an explanation of the contractual relationship between Laitram and ION, see “— Certain Transactions and Relationships” below.

Committees of the Board

     The Board of Directors has established four standing committees to facilitate and assist the Board in the execution of its responsibilities. The four standing committees are the Audit Committee, the Compensation Committee, the Governance Committee and the Finance Committee. The Governance Committee functions as the Board’s Nominating Committee. In addition, the Board establishes temporary special committees on an as-needed basis. The Audit Committee, Compensation Committee and Governance Committee are composed entirely of non-employee directors. The Finance Committee consists of three directors, two of whom are non-employee directors. During 2008, the Audit Committee met five times, the Compensation Committee met six times, the Governance Committee met seven times, and the Finance Committee met two times.

     The current members of the four standing committees of the Board of Directors are identified below.

Audit Committee

     The Audit Committee is a separately-designated standing audit committee as defined in Section 3(a)(58)(A) of the Exchange Act. The Audit Committee oversees matters relating to financial reporting, internal controls, risk management and compliance. These responsibilities include appointing, overseeing, evaluating and approving the fees of our independent auditors, reviewing financial information that is provided to our stockholders and others, reviewing with management our system of internal controls and financial reporting process, and monitoring our compliance program and system.

     The Audit Committee operates under a written charter, which sets forth the functions and responsibilities of the committee. A copy of the charter can be viewed on our website at http://www.iongeo.com/content/released/audit_committee_charter_ion_march52008.pdf

     The Board of Directors has determined that each member of the Audit Committee is financially literate and satisfies the definition of “independent” as established in the NYSE corporate governance listing standards. In addition, the Board of Directors has determined that Mr. Nelson, the Chairman of the Audit Committee, is qualified as an audit committee financial expert within the meaning of SEC regulations, and that he has accounting and related financial management expertise within the meaning of the listing standards of the NYSE and Rule 10A-3 under the Exchange Act.

     ION’s Corporate Governance Guidelines provide that no member of the Audit Committee may simultaneously serve on the audit committees of more than two other public companies unless the ION Board determines that such simultaneous service would not impair the ability of such director to effectively serve on ION’s Audit Committee.

Compensation Committee

     The Compensation Committee has responsibility for the compensation of our executive officers, including our chief executive officer, and the administration of our executive compensation and benefit plans. The Compensation Committee also has authority to retain or replace outside counsel, compensation and benefits consultants or other experts to provide it with independent advice, including the authority to approve the fees payable and any other terms of retention. All actions regarding executive officer compensation require Compensation Committee approval. The Compensation Committee completes a comprehensive review of all elements of compensation at least annually. If it is determined that any changes to any executive officer’s total compensation are necessary or appropriate, the Compensation Committee obtains such input from management as it determines to be necessary or appropriate. All compensation decisions with respect to executives other than the chief executive officer are determined in discussion with, and frequently based in part upon the recommendation of, the chief executive officer. The Compensation Committee makes all determinations with respect to the compensation of the chief executive officer, including, but not limited to, establishing performance objectives and criteria related to the payment of his compensation, and determining the extent to which such objectives have been established, obtaining such input from the Committee’s independent compensation advisors as it deems necessary or appropriate.

     As part of its responsibility to administer our executive compensation plans and programs, the Compensation Committee, usually near the beginning of the calendar year, establishes the parameters of the annual incentive plan awards, including establishing the performance goals relative to our performance that will be applicable to such awards and the similar awards for our other senior executives. It also reviews our performance against the objectives established for awards payable in respect of the prior calendar year, and confirms the extent, if any, to which such objectives have been obtained, and the amounts payable to each of our executive officers in respect of such achievement.

     The Compensation Committee also determines the appropriate level and type of awards, if any, to be granted to each of our executive officers pursuant to our equity compensation plan, and approves the total annual grants to other key employees, to be granted in accordance with a delegation of authority to our corporate human resources officer.

     The Compensation Committee reviews, and has the authority to recommend to the Board for adoption, any new executive compensation or benefit plans that are determined to be appropriate for adoption by ION, including those that are not otherwise subject to the approval of our stockholders. It reviews any contracts or other transactions with current or former elected officers of the corporation. In connection with the review of any such proposed plan or contract, the Compensation Committee may seek from its independent advisors such advice, counsel and information as it determines to be appropriate in the conduct of such review. The Compensation Committee will direct such outside advisors as to the information it requires in connection with any such review, including data regarding competitive practices among the companies with which ION generally compares itself for compensation purposes.

     The Compensation Committee operates pursuant to a written charter that sets forth the functions and responsibilities of the committee. A copy of the charter can be viewed on our website at http://www.iongeo.com/content/released/comp_ committee_charterionfeb_2008.pdf. The Board of Directors has determined that each member of the Compensation Committee satisfies the definition of “independent” as established in the NYSE corporate governance listing standards.

Compensation Committee Interlocks and Insider Participation

     The members of the Compensation Committee are Franklin Myers (Chairman), James M. Lapeyre, Jr. and John N. Seitz. No member of the Committee is, or was during 2007, an officer or employee of ION. Mr. Sam K. Smith (who was a member of the Compensation Committee until his retirement from the Board in August 2008) was formerly an officer of ION, serving as our interim Chief Executive Officer from 1999 to 2000. Mr. Lapeyre is President and Chief Executive Officer and a significant equity owner of Laitram, L.L.C, which has had a business relationship with ION since 1999 that continued into 2008. During 2008, we paid Laitram and its affiliates a total of approximately $4.3 million, which consisted of approximately $3.4 million for manufacturing services, $800,000 for rent and other pass-through third party facilities charges, and $100,000 for other services. See “ — Certain Transactions and Relationships” below. During 2008:

	•		No executive officer of ION served as a member of the compensation committee of another entity, one of whose executive officers served on the Compensation Committee of ION;
	•		No executive officer of ION served as a director of another entity, one of whose executive officers served on the Compensation Committee of ION; and
	•		No executive officer of ION served as a member of the compensation committee of another entity, one of whose executive officers served as a director of ION.

Governance Committee

     The Governance Committee functions as the Board’s nominating and corporate governance committee and advises the Board of Directors with regard to matters relating to governance practices and policies, management succession, and composition and operation of the Board and its committees, including reviewing potential candidates for membership on the Board and recommending to the Board nominees for election as directors of ION. In addition, the Governance Committee reviews annually with the full Board and our Chief Executive Officer the succession plans for senior executive officers and makes recommendations to the Board regarding the selection of individuals to occupy these positions.

     In identifying and selecting new director candidates, the Governance Committee considers the Board’s current and anticipated strengths and needs and a candidate’s experience, knowledge, skills, expertise, integrity, diversity, ability to make independent analytical inquiries, understanding of the company’s business environment, willingness to devote adequate time and effort to Board responsibilities, and other relevant factors. The Governance Committee has not established specific minimum age, education, years of business experience or specific types of skills for potential director candidates, but, in general, expects that qualified candidates will have ample experience and a proven record of business success and leadership. The committee also seeks an appropriate balance of experience and expertise in accounting and finance, technology, management, international business, compensation, corporate governance, strategy, industry knowledge and general business matters. The Governance Committee may rely on various sources to identify potential director nominees, including input from directors, management and others the committee feels are reliable, and professional search firms. During 2008, the Governance Committee engaged a search firm to assist it in identifying and facilitating the screening and interview process of candidates for director to replace Mr. Sam K. Smith, who retired from the Board in August 2008. In December 2008, upon the recommendation of the Governance Committee, Messrs. Marsh and Vlahakis were appointed to the Board as new directors.

     The Governance Committee will consider recommendations for director nominations made by a stockholder or other sources (including self-nominees) on the same basis as other candidates. For consideration by the Governance Committee, a recommendation of a candidate must be submitted in writing to the Governance Committee in care of our Corporate Secretary at our principal executive offices. The submission must include sufficient details regarding the qualifications of the potential candidate. In general, nominees for election should possess (1) the highest level of integrity and ethical character, (2) strong personal and professional reputation, (3) sound judgment, (4) financial literacy, (5) independence, (6) significant experience and proven superior performance in professional endeavors, (7) an appreciation for board and team performance, (8) the commitment to devote the time necessary, (9) skills in areas that will benefit the Board and (10) the ability to make a long-term commitment to serve on the Board.

     Also, our Bylaws permit stockholders to nominate individuals for director for consideration at an annual stockholders’ meeting. A proper director nomination may be considered at ION’s 2010 Annual Meeting only if the proposal for nomination is received by ION not later than December 24, 2009. All nominations should be directed to David L. Roland, Senior Vice President, General Counsel and Corporate Secretary, ION Geophysical Corporation, 2105 CityWest Boulevard, Suite 400, Houston, Texas 77042-2839.

     The Governance Committee operates pursuant to a written charter, which sets forth the functions and responsibilities of the committee. A copy of the charter can be viewed on our website at http://www.iongeo.com/content/released/Governance_Committee_Charter-ION.pdf. The Board of Directors has determined that each member of the Governance Committee satisfies the definition of “independent” as established in the NYSE corporate governance listing standards.

Finance Committee

     The Finance Committee has responsibility for overseeing all areas of corporate finance for ION. The Finance Committee is responsible for reviewing with ION management, and has the power and authority to approve on behalf of the Board, ION’s strategies, plans, policies and actions related to corporate finance, including, but not limited to, (a) capital structure plans and strategies and specific equity or debt financings, (b) capital expenditure plans and strategies and specific capital projects, (c) strategic and financial investment plans and strategies and specific investments, (d) cash management plans and strategies and activities relating to cash flow, cash accounts, working capital, cash investments and treasury activities, including the establishment and maintenance of bank, investment and brokerage accounts, (e) financial aspects of insurance and risk management, (f) tax planning and compliance, (g) dividend policy, (h) plans and strategies for managing foreign currency exchange exposure and other exposures to economic risks, including plans and strategies with respect to the use of derivatives, and (i) reviewing and making recommendations to the Board with respect to any proposal by ION to divest any asset, investment, real or personal property, or business interest if such divestiture is required to be approved by the Board. The Finance Committee does not have oversight responsibility with respect to ION’s financial reporting, which is the responsibility of the Audit Committee.

     The Finance Committee operates pursuant to a written charter that sets forth the functions and responsibilities of the committee. A copy of the charter can be obtained by writing to us at ION Geophysical Corporation, Attention: Corporate Secretary, 2105 CityWest Boulevard, Suite 400, Houston, Texas 77042-2839. The Board of Directors has determined that a majority of the members of the Finance Committee (including its co-Chairmen) satisfies the definition of “independent” as established in the NYSE corporate governance listing standards.

Stock Ownership Requirements

     The Board adopted stock ownership requirements for ION’s directors effective January 2006 and revised the requirements effective January 2009. The Board adopted these requirements in order to align the economic interests of the directors with those of our stockholders and further focus our emphasis on enhancing stockholder value. Under these requirements, each non-employee director is expected to own at least 36,000 shares of ION stock. New and current directors will have three years to increase the director’s ownership of ION stock to satisfy the requirements. The stock ownership requirements are subject to modification by the Board in its discretion. The Board has also adopted stock ownership requirements for senior management of ION. See “Executive Compensation — Compensation Discussion and Analysis — Elements of Compensation — Stock Ownership Requirements; Hedging Policy” below.

     The Governance Committee and the Board regularly review and evaluate ION’s directors’ compensation program on the basis of current and emerging compensation practices for directors, emerging legal, regulatory and corporate compliance developments and comparisons with director compensation programs of other similarly-situated public companies.

Certain Transactions and Relationships

     Mr. Lapeyre is the President and Chief Executive Officer and a significant equity owner of Laitram, L.L.C. and has served as President of Laitram and its predecessors since 1989. Laitram is a privately-owned, New Orleans-based manufacturer of food processing equipment and modular conveyor belts. Mr. Lapeyre and Laitram together owned approximately 9.4% of our outstanding common stock as of February 20, 2009.

     We acquired DigiCourse, Inc., our marine positioning products business, from Laitram in 1998 and renamed it I/O Marine Systems, Inc. In connection with that acquisition, we entered into a Continued Services Agreement with Laitram under which Laitram agreed to provide us with certain accounting, software, manufacturing and maintenance services. Manufacturing services consist primarily of machining of parts for our marine positioning systems. The term of this written agreement expired in September 2001 but we and Laitram continue to operate under its terms. In addition, when we have requested, the legal staff of Laitram has advised us on certain intellectual property matters with regard to our marine positioning systems. Under a Lease of Commercial Property dated February 1, 2006, between Lapeyre Properties, L.L.C. (an affiliate of Laitram) and I/O Marine Systems, Inc., we agreed to lease certain office and warehouse space from Lapeyre Properties until January 2011. During 2008, we paid Laitram and its affiliates a total of approximately $4.3 million, which consisted of approximately $3.4 million for manufacturing services, $800,000 for rent and other pass-through third party facilities charges, and $100,000 for other services. For the 2007 and 2006 fiscal years, we paid Laitram and its affiliates a total of approximately $4.9 million and $3.6 million, respectively, for these services. In the opinion of our management, the terms of these services are fair and reasonable and as favorable to us as those that could have been obtained from unrelated third parties at the time of their performance.

the past and provided further that the aggregate amount involved does not exceed the greater of $1,000,000 or 2% of Laitram’s total annual revenues.

	d.		Certain ION charitable contributions. Any charitable contribution, grant or endowment by ION to a charitable organization, foundation or university at which a Related Person’s only relationship is as a volunteer, an employee (other than an executive officer) or a director, regent or similar position, if the aggregate amount involved does not exceed the greater of $100,000 or 2% of the charitable organization’s total annual receipts.
	e.		Transactions where all shareholders receive proportional benefits. Any transaction where the Related Person’s interest arises solely from the ownership of ION’s common stock and all holders of ION’s common stock received the same benefit on a pro rata basis (e.g., dividends).

Introduction/Corporate Governance

Compensation Committee

     The Compensation Committee of our Board of Directors reviews and approves, or recommends to the Board for approval, all salary and other remuneration for our executive officers and oversees matters relating to our employee compensation and benefit programs. The Committee is composed of the following directors:

Franklin Myers, Chairman
James M. Lapeyre, Jr.
John N. Seitz

     No member of the Committee is an employee of ION. The Board of Directors has determined that each member of the Committee satisfies the definition of “independent” as established in the NYSE corporate governance listing standards.

     The Committee operates pursuant to a written charter that sets forth its functions and responsibilities. A copy of the charter can be viewed on our website at http://www.iongeo.com/content/released/comp_committee_charterionfeb _2008.pdf. The Chairman of the Committee is in charge of the Committee’s meeting agendas and, with the assistance of our Corporate Secretary, establishes the Committee’s meetings and calendar. For a description of the responsibilities of

the Compensation Committee, see “Item 1. — Election of Directors — Committees of the Board — Compensation Committee” above.

Compensation Consultants

     Each year from 2005 to 2008, the Compensation Committee has retained Towers Perrin as its independent compensation advisor to advise the Committee on our compensation practices and to assist in developing and implementing our executive compensation program and philosophy. Towers Perrin evaluated our long-term incentive strategy and our stock plans, analyzed our outstanding stock options, restricted stock and other stock-based awards, and provided the Committee with recommendations on our overall long-term incentive strategy and the number of shares to propose to add to our stock plans for future grants to employees and directors, which the Committee and the Board of Directors later approved. In addition, the firm provided the Committee with a summary of changes to disclosure requirements related to executive officer and director compensation. At the request of the Committee, the firm also performed an analysis of competitive compensation levels for our Chief Executive Officer. During 2008, the Governance Committee of our Board retained Hewitt Associates to perform an analysis of prevailing industry compensation levels for our directors. During the first quarter of 2009, the Compensation Committee engaged Performensation Consulting, an equity compensation consultant, to assist the company and the Compensation Committee in designing a proposed new employee stock purchase plan and a plan to permit our current employees to exchange outstanding stock options having exercise prices substantially above the current market price of our common stock, and receive shares of our common stock. During 2008 and the first quarter of 2009, none of Towers Perrin, Hewitt Associates or Performensation Consulting advised our company or our executive officers on matters outside of these engagements by the Board or its committees.

Role of Management in Establishing and Awarding Compensation

     On an annual basis, our Chief Executive Officer, with the assistance of our Human Resources department, recommends to the Compensation Committee any proposed increases in base salary, bonus payments and equity awards for our executive officers other than himself. No executive officer is involved in determining his own salary increase, bonus payment or equity award. When making officer compensation recommendations, our Chief Executive Officer takes into consideration compensation benchmarks, which include industry standards for similar sized organizations serving similar markets, as well as comparable positions, the level of inherent importance and risk associated with the position and function, and the executive’s job performance over the previous year. See “— Objectives of Our Executive Compensation Programs — Benchmarking” and “— Elements of Compensation — Base Salary” below.

     Our Chief Executive Officer, with the assistance of our Human Resources department and input from our executive officers and other members of senior management, also formulates and proposes to the Compensation Committee an employee bonus incentive plan for the ensuing year. For a description of our process for formulating the employee bonus incentive plan and the factors that we consider, see “— Elements of Compensation — Annual Incentive Compensation” below.

     The Committee reviews and approves all compensation and awards to executive officers and all bonus incentive plans. With respect to equity compensation awarded to employees other than executive officers, the Compensation Committee reviews and approves all grants of restricted stock and stock options above 5,000 shares, generally based upon the recommendation of the Chief Executive Officer, and has delegated option and restricted stock granting authority to the Chief Executive Officer for grants to non-executive officers of up to 5,000 shares. Our Chief Executive Officer provides a report to the Compensation Committee of all options and restricted stock awarded by him under this delegated authority.

     On its own initiative, at least once a year, the Compensation Committee reviews the performance and compensation of our Chief Executive Officer and, following discussions with the Chief Executive Officer and other members of the Board of Directors, establishes his compensation level. Where it deems appropriate, the Compensation Committee will also consider market compensation information from Towers Perrin or other independent sources. See “— Objectives of Our Executive Compensation Programs — Benchmarking” below.

     Certain members of our senior management generally attend most meetings of the Compensation Committee, including our Chief Executive Officer, our President, our Senior Vice President — Global Human Resources, and our General Counsel/Corporate Secretary. However, no member of management votes on items before the Compensation Committee. The Compensation Committee and Board of Directors do solicit the views of our Chief Executive Officer on compensation matters, particularly as they relate to the compensation of the other named executive officers and the other members of senior management reporting to the Chief Executive Officer. The Committee often conducts an executive session during each meeting, during which members of management are not present.

Compensation Committee Activity

     During 2008, the Compensation Committee met in person or by conference call six times. In three of those meetings, the Committee also met in executive session with no members of management present. All members of the Committee participated in all meetings. In addition to the six meetings mentioned above, the Committee took action by unanimous written consent, as permitted under Delaware law and our Bylaws, five times during 2008, primarily to approve individual non-executive employee grants of restricted stock and stock options. We believe that each of these individual grants made by unanimous written consent of the Committee complied with the applicable grant date requirements under Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment” (“FAS 123R”).

     During 2008 and the first quarter of 2009, the Committee took the following actions:

	•		Reviewed the 2008 and 2009 employee bonus plans submitted by our Chief Executive Officer and approved each plan after making desired revisions.
	•		Considered and approved employee bonus awards payable under our 2007 and 2008 bonus plans and discretionary bonus awards for certain employees in recognition of their performance during 2007 and 2008.
	•		Engaged Towers Perrin for:

	•		an analysis of our 2008 long-term incentive strategy, our stock plans and our outstanding stock options, restricted stock and other stock-based awards, and
	•		a recommendation on our strategy and the number of shares to propose to add to our stock plans in 2008 for future grants to employees and directors.

•

Engaged Hewitt Associates for:

	•		an analysis of our 2009 long-term incentive strategy, our stock plans and our outstanding stock options, restricted stock and other stock-based awards, and
	•		a recommendation on our strategy in 2009 with regards to future grants to employees and directors.

	•		Engaged Performensation Consulting to assist in designing a new employee stock purchase plan (which we and the Committee decided not to pursue for 2009) and the Replenishment Program.
	•		Approved amendments to our 2004 Long-Term Incentive Plan, as recommended by Towers Perrin in 2008, to increase the number of shares available for grant to employees and directors under the plan and recommended the proposed amendments to our Board to be submitted to our stockholders for approval at our 2008 annual stockholders’ meeting.
	•		Participated in the Board review of the succession plan for our Chief Executive Officer and other key members of senior management.

	•		Considered and approved annual base salary increases for individual executive officers and the overall percentage of annual base salary increase applicable to our employees as a whole.
	•		Considered and approved annual employee stock option and restricted stock awards, including awards for individual executive officers.
	•		Approved certain amendments to the employment agreements of our Chief Executive Officer and Chief Financial Officer for review by the Board and approved an employment agreement for our President and Chief Operating Officer for review by the Board.
	•		Reviewed and recommended to the Board for approval a stock appreciation rights plan.
	•		Approved grants of restricted stock, stock options, restricted stock units and stock appreciation rights to various employees.
	•		Considered and approved, subject to stockholder approval, the Replenishment Program, which will permit certain of our current employees to exchange certain outstanding stock options having exercise prices substantially above the current market price of our common stock, and receive shares of our common stock. For more information on this proposed program, please refer to “Item 2 — Approval of an Employee Equity Replenishment Program” of this proxy statement.
	•		Reviewed and discussed with management this Compensation Discussion and Analysis.

Objectives of Our Executive Compensation Programs

General Compensation Philosophy and Policy

     Through our compensation programs, we seek to achieve the following general goals:

	•		attract and retain qualified and productive executive officers and key employees by providing total compensation competitive with that of other executives and key employees employed by companies of similar size, complexity and industry of business;
	•		encourage our executives and key employees to achieve strong financial and operational performance;
	•		offer performance-based compensation to create meaningful links between corporate performance, individual performance and financial rewards;
	•		align the interests of our executives with those of our stockholders by providing a significant portion of total pay in the form of stock-based incentives;
	•		encourage long-term commitment to our company; and
	•		limit corporate perquisites to seek to avoid perceptions both within and outside of our company of “soft” compensation.

     Our governing principles in establishing executive compensation have been:

     Long-Term and At-Risk Focus. Premium compensation opportunities should be composed of long-term, at-risk pay to focus our management on the long-term interests of our company. Base salary, annual incentives and employee benefits should be at competitive levels when compared to similarly-situated companies.

     Equity Orientation. Equity-based plans should comprise a major part of the at-risk portion of total compensation to instill ownership thinking and to link compensation to corporate performance and stockholder interests.

     Competitive. We emphasize total compensation opportunities consistent on average with our peer group of companies. Competitiveness of annual base pay and annual incentives is independent of stock performance. However, overall competitiveness of total compensation is generally contingent on long-term, stock-based compensation programs.

     Focus on Total Compensation. In making decisions with respect to any element of an executive officer’s compensation, the Committee obtains information on and considers the total compensation that may be awarded to the executive officer, including salary, annual bonus and long-term incentive compensation. These total compensation reports are prepared by our Human Resources department and present the dollar amount of each component of the named executive officers’ compensation, including current cash compensation (base salary, past bonus and eligibility for future bonus), equity awards and other compensation. The overall purpose of these total compensation reports is to bring together, in one place, all of the elements of actual and potential compensation of our named executive officers, as well as information about wealth accumulation, so that the Compensation Committee may analyze both the individual elements of compensation (including the compensation mix) as well as the aggregate total amount of actual and projected compensation. In its most recent review of total compensation reports, the Committee determined that annual compensation amounts for our Chief Executive Officer and our other named executive officers remained generally consistent with the Committee’s expectations. However, the Committee reserves the right to make changes that it believes are warranted. For example, in 2007 the Committee decided that the equity compensation mix for our Chief Executive Officer needed to achieve a better balance between restricted stock and stock options by adjusting on a going-forward basis to include a combination of restricted stock and stock options rather than solely stock options (as in 2003) or solely restricted stock (as in 2006).

     More recently, in April 2009, the Committee approved and the company implemented an employee base salary reduction program, including reductions to base salaries for the named executive officers, to reduce company operating costs during the recent market downturn resulting from the economic recession and decline in oil and gas prices. As a result of the market downturn, our stock price has declined to historic low levels, resulting in our employees holding stock options with exercise prices that greatly exceed both the current market price of ION common stock and the average market price of our stock over the prior 12 months. The Committee has recognized that these underwater options no longer provide the long-term incentive and retention objectives that they were intended to provide. As a result, the Board and the Committee have proposed and recommended that the company’s stockholders approve the Replenishment Program, which will permit certain of our current employees to exchange certain outstanding stock options having exercise prices substantially above the current market price of our common stock, and receive shares of our common stock. For more information on this proposed program, please refer to “Item 2 — Approval of an Employee Equity Replenishment Program” of this proxy statement.

     Internal Pay Equity. Our core compensation philosophy is to pay our executive officers competitive levels of compensation that best reflect their individual responsibilities and contributions to our company, while providing incentives to achieve our business and financial objectives. While comparisons to compensation levels at other companies (discussed below) is helpful in assessing the overall competitiveness of our compensation program, we believe that our executive compensation program also must be internally consistent and equitable in order for our company to achieve our corporate objectives. Each year our Human Resources department reports to the Compensation Committee the total compensation paid to our Chief Executive Officer and all other senior executives, which includes a comparison for internal pay equity purposes. Over time there have been variations in the comparative levels of compensation of executive officers and changes in the overall composition of the management team and the overall accountabilities of the individual executive officers; however, we and the Committee are satisfied that total compensation received by executive officers reflects an appropriate differential for executive compensation.

     These principles apply to compensation policies for all of our executive officers and key employees. We do not follow the principles in a mechanistic fashion; rather, we apply experience and judgment in determining the appropriate mix of compensation for each individual. This judgment also involves periodic review of discernible measures to determine the progress each individual is making toward agreed-upon goals and objectives.

Benchmarking

     When making compensation decisions, we also look at the compensation of our Chief Executive Officer and other executive officers relative to the compensation paid to similarly-situated executives at companies that we consider to be our industry and market peers — a practice often referred to as “benchmarking.” We believe, however, that a benchmark should be just that — a point of reference for measurement — but not the determinative factor for our executives’ compensation. The purpose of the comparison is not to supplant the analyses of internal pay equity, total wealth accumulation and the individual performance of the executive officers that we consider when making compensation decisions. Because the comparative compensation information is just one of the several analytic tools that are used in setting executive compensation, the Compensation Committee has discretion in determining the nature and extent of its use. Further, given the limitations associated with comparative pay information for setting individual executive compensation, including the difficulty of assessing and comparing wealth accumulation through equity gains, the Committee may elect to not use the comparative compensation information at all in the course of making compensation decisions.

     At least once each year, generally in or around August, our Human Resources department, under the oversight of the Compensation Committee, reviews data from market surveys, independent consultants and other sources to assess our competitive position with respect to base salary, annual incentives and long-term incentive compensation.

     When reviewing compensation data in 2008, we utilized data primarily from Radford salary surveys, the Mercer Global Planning Report 2009 and the WorldatWork 2007 — 2008 Salary Budget Survey. The survey information from these three resources covered a broad range of industries and companies. For example, the WorldatWork Salary Budget Survey covers 2,800 participating organizations. When reviewing compensation data in 2006 with regard to the compensation of our Chief Executive Officer, the Compensation Committee engaged Towers Perrin to perform a marketplace compensation analysis. In the study, the firm presented data to the Committee from the Towers Perrin 2005 Energy Industry Incentive Survey, the Mercer Human Resource Consulting 2005 Energy Compensation Survey and a proxy compensation analysis for the Chief Executive Officer position among a group of ten industry peer companies. These industry peer companies were:

Global Industries Ltd.		OYO Geospace Corp.
Horizon Offshore Inc.		TETRA Technologies Inc.
Cal Dive International Inc.		Veritas DGC Inc.
Intergraph Corp.		Grant Prideco Inc.
Oceaneering International Inc.		Oil States International Inc.

     When determining compensation for Mr. Hollis when he was promoted to President and Chief Operating Officer in December 2008, we utilized data primarily from the Oilfield Manufacturing & Services Industry (OFMS) Executive Survey and executive surveys from Radford, Mercer and Towers Perrin. The OFMS survey compiles survey results and/or proxy compensation data from the following oilfield services companies:

Baker Hughes Incorporated		Hydril Company LP
Bristow Group Inc.		ION Geophysical Corporation
Complete Production Services, Inc.		National Oilwell Varco, Inc.
Cameron International Corporation		Newpark Resources, Inc.
Core Laboratories		Oil States International Inc.
ENSCO, Inc.		Pride International, Inc.
FMC Technologies, Inc.		Rowan Companies, Inc.
GlobalSantaFe (now Transocean Inc.)		Smith International, Inc.
Gulfmark Offshore, Inc.		TIW Corporation
Halliburton Company		VetcoGray
Hanover Compressor (now Exterran)		Warren Equipment Company

     The overall results of the Towers Perrin analysis (with regard to Chief Executive Officer compensation) and the consulting firm surveys (with regard to compensation for all other levels within our company) provide the starting point for our compensation analysis. We believe that the surveys and the Towers Perrin analysis contain relevant compensation information from companies that are representative of the sector in which we operate, have relative size

as measured by market capitalization, and experience relative complexity in the business and the executives’ roles and responsibilities.

     Beyond the report and survey numbers, we look extensively at a number of other factors, including our estimates of the compensation at our most comparable competitors and other companies that were closest to our company in size, profitability and complexity. We also consider an individual’s current performance, the level of corporate responsibility, and the employee’s skills and experience, collectively, in making compensation decisions.

     In the case of our Chief Executive Officer and some of our other executive officers, we also consider our company’s performance during the person’s tenure, and the anticipated level of difficulty of replacing the person with someone of comparable experience and skill. When we hired R. Brian Hanson as our new Executive Vice President/Chief Financial Officer in May 2006, for example, we based our total compensation ranges for the position primarily on our direct experience and observations regarding competitive compensation packages for candidates possessing requisite levels of senior executive-level financial management experience, expertise and achievement.

     In addition to our periodic review of compensation, we also regularly monitor market conditions and will adjust compensation levels from time to time as necessary to remain competitive and retain our most valuable employees. When we experience a significant level of competition for retaining current employees or hiring new employees, we will typically reevaluate our compensation levels within that employee group in order to ensure our competitiveness.

Elements of Compensation

     The primary components of our compensation are:

	•		base salary;
	•		performance-based annual incentive compensation; and
	•		long-term equity-based incentive compensation, such as stock options, restricted stock, restricted stock units and stock appreciation rights.

     Below is a summary of each component:

Base Salary

     General. The general purpose of base salary for our executive officers is to create a base of cash compensation for the officer that is consistent on average with the range of base salaries for executives in similar positions and with similar responsibilities at comparable companies. In addition to salary norms for persons in comparable positions at comparable companies, base salary amounts may also reflect the nature and scope of responsibility of the position, the expertise of the individual employee and the competitiveness of the market for the employee’s services. Base salaries of executives other than our Chief Executive Officer may also reflect our Chief Executive Officer’s evaluation of the individual executive officer’s job performance. As a result, the base salary level for each individual may be above or below the target market value for the position. The Compensation Committee also recognizes that the Chief Executive Officer’s compensation should reflect the greater policy- and decision-making authority that he holds and the higher level of responsibility he has with respect to our strategic direction and our financial and operating results. At December 31, 2008, our Chief Executive Officer’s annual base salary was 49% higher than the annual base salary for the next highest-paid executive officer. In addition, minimum base salaries for certain of our executive officers are determined by employment agreements with these officers.

     Base salary is designed to provide an income level that is comparable to the income of executives in similar positions and with similar responsibilities at comparable companies. The base salaries for our executives reflect levels that we have concluded were appropriate based upon our general experience and market data. We do not intend for base salaries to be the vehicle for long-term capital and value accumulation for our executives.

     2008 Actions. Base salaries are reviewed at least annually and may also be adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities and changes in responsibilities,

performance and contribution to ION, experience, impact on total compensation, relationship of compensation to other ION officers and employees, and changes in market levels. Salary increases for executive officers do not follow a preset schedule or formula but do take into account changes in the market and individual circumstances. In 2008, base salary levels were reviewed and adjusted during August and September.

     Below is a summary of actions taken during 2008 with respect to base salaries of the named executive officers:

Named Executive Officer		Action
Robert P. Peebler		During 2008, CEO compensation surveys from Radford and Towers Perrin indicated that the 50th percentile for CEO base salary for the companies included in these surveys was an average of $620,000. Based on the results of the reports, and in recognition of our performance to date and Mr. Peebler’s unique experience, expertise, and capabilities, in September 2008 the Compensation Committee increased Mr. Peebler’s annual base salary from $525,000 to $575,000.
R. Brian Hanson		During 2008, CFO compensation surveys from Radford indicated that the 50th percentile for CFO base salary for the companies included in these surveys was $335,076. Based on the results of the reports, in September 2008 the Compensation Committee increased Mr. Hanson’s annual base salary from $300,000 to $327,000.
James R. Hollis		During 2008, COO compensation surveys from Radford and Towers Perrin indicated that the 50th percentile for COO base salary for the companies included in these surveys was $332,550. Based on the results of the reports, in September 2008 the Compensation Committee increased Mr. Hollis’ annual base salary as the Executive Vice President and COO of ION Solutions from $300,000 to $327,000. In December 2008, in connection with Mr. Hollis’ promotion to President and COO of our company, the Compensation Committee reviewed President/COO compensation data from Towers Perrin, Radford, the OFMS Executive Survey and Mercer indicating that the 50th percentile for President/COO base salary for the companies included in these surveys was $385,642, and increased Mr. Hollis’ annual base salary from $327,000 to $385,000.
Teng Beng Koid		During 2008, compensation surveys from Radford and Towers Perrin indicated that the 50th percentile for senior worldwide sales executive base salary for the companies included in these surveys was $295,000. Based on the results of the reports, in September 2008 the Compensation Committee increased Mr. Koid’s annual base salary from $275,000 to $291,500.
Charles J. Ledet		During 2008, compensation surveys from Radford and Towers Perrin indicated that the 50th percentile for COO base salary for the companies included in these surveys was $332,550. Based on the results of the reports, in September 2008 the Compensation Committee increased Mr. Ledet’s annual base salary from $300,000 to $312,000. Mr. Ledet’s employment with ION ended on December 1, 2008.
Christopher M. Friedemann		During 2008, compensation surveys from Radford and Towers Perrin indicated that the 50th percentile for senior marketing executive base salary for the companies included in these surveys was $230,500. Based on the results of the reports and in recognition of Mr. Friedemann’s performance, expertise, and capabilities, in September 2008 the Compensation Committee increased Mr. Friedemann’s annual base salary from $245,000 to $262,150.

     Base Salary Reduction Program. Commencing in late 2008, our business has experienced a significant decline, due in large part to the current global recession and the decline in oil and gas prices, as well as other factors,

that have negatively impacted demand for our products and services and thus adversely affected our financial results. We have taken a number of actions to reduce costs in our businesses and seek to improve our operating performance. In late 2008 we decided to defer any future base salary increases for employees until 2010. Then, in April 2009, we implemented a base salary reduction program in a further effort to reduce our operating costs. Under the salary reduction program, base salaries for employees were reduced by certain percentages, ranging from a 12% reduction in base salary for our Chief Executive Officer, Chief Financial Officer and Chief Operating Officer, a 10% reduction for other executives and management and a 5% reduction for most other employees. The program will remain in effect until management and the Board determines that our operating results have improved to the extent that the program should end. Under the program, the salaries for our current named executive officers were reduced as follows:

Named Executive Officer		Reduction in Base Salary
Robert P. Peebler		Reduced from $575,000 to $506,000
R. Brian Hanson		Reduced from $327,000 to $287,760
James R. Hollis		Reduced from $385,000 to $338,800
Teng Beng Koid		Reduced from $291,500 to $262,350
Christopher M. Friedemann		Reduced from $262,150 to $235,935

Annual Incentive Compensation

     Our employee annual bonus incentive plan is intended to promote the achievement each year of company performance objectives and performance objectives of the employee’s particular business unit, and to recognize those employees who contributed to the company’s achievements. The plan provides cash compensation that is at-risk on an annual basis and is contingent on achievement of annual business and operating objectives and individual performance. The plan provides all participating employees the opportunity to share in the company’s performance through the achievement of established financial and individual objectives. The financial and individual objectives within the plan are intended to measure an increase in the value of our company and, in turn, our stock.

     In recent years, we have adopted an annual incentive plan with regard to each year. Performance under the annual incentive plan is measured with respect to the designated plan fiscal year. Payments under the plan are paid in cash in an amount reviewed and approved by the Compensation Committee and are ordinarily made in a single installment in the first quarter following the completion of a fiscal year, after the financial results for that year have been determined.

     Our annual incentive plan is usually consistent with our operating plan for the same year. In late 2007, we prepared a consolidated company operating budget for 2008 and individual operating budgets for each operating unit. The budgets took into consideration market opportunities, customer and sale opportunities, technology enhancements for new products, product manufacturing and delivery schedules and other operating factors. The Board of Directors analyzed the proposed budgets with management extensively and, after analysis and consideration, the Board approved the consolidated 2008 operating plan. During late 2007 and early 2008, our Chief Executive Officer worked with our Human Resources department and members of senior management to formulate our 2008 incentive plan, consistent with the 2008 operating plans approved by the Board.

     At the beginning of 2008, the Compensation Committee approved our 2008 annual incentive plan for executives and designated non-executive key employees. The computation of awards generated under the plan is required to be approved by the Committee. In February 2009, the Committee reviewed the company’s actual performance against each of the plan performance goals established at the beginning of the year and evaluated each individual’s performance during the preceding year. The results of operations of the company for that year and individual performance evaluations determined the appropriate payout under the annual incentive plan.

     The Compensation Committee has discretion in circumstances it determines are appropriate to authorize discretionary incentive compensation awards that might exceed amounts that would otherwise be payable under the terms of the incentive plan. These discretionary awards can be payable in cash, stock options, restricted stock, restricted stock units, stock appreciation rights or a combination thereof. Any stock options, restricted stock or restricted stock units awarded would be granted under one of our existing long-term equity incentive plans. Any stock appreciation rights awarded would be granted under our Stock Appreciation Rights Plan. The Committee also has the discretion, in appropriate circumstances, to grant a lesser incentive award, or no incentive award at all, under the incentive plan. The Committee intends to review our annual incentive compensation program annually to ensure that the key elements of the program continue to meet the objectives described above.

     Below is a general description of our 2008 incentive plan and a general summary of the company performance criteria applicable to the plan, as well as our variable payment plan we adopted in 2009.

 

     2008 Incentive Plan. The purpose of the 2008 incentive plan was to:

	•		provide an incentive for our participating employees to achieve their highest level of individual and team performance in order to accomplish our company’s 2008 strategic and financial goals, and
	•		reward the employees for those achievements and accomplishments.

     Designated employees, including our named executive officers, were eligible to participate in our 2008 incentive plan. The 2008 incentive plan was designed to equate the size of the incentive award to the performance of the individual participant and the performance of our company as a whole. Every participating named executive officer had the opportunity to earn an incentive payment based on their performance against criteria as defined by our Chief Executive Officer, and achievement of our company’s performance against designated consolidated financial objectives. Award determinations for the named executive officers under the plan were also based on evaluations of employee performance by our Chief Executive Officer. Under the 2008 incentive plan, 25% of the funds allocated for distribution were available to award to eligible employees regardless of the company’s 2008 financial performance, and 75% of the funds were available for distribution to eligible employees only to the extent the company satisfied the designated 2008 financial performance criteria. As a result, the amount of total dollars available for distribution under the incentive plan was largely dependent on the company’s achievement of the pre-defined financial objectives.

     As reported in the chart below, our 2008 incentive plan established a 2008 target consolidated operating income performance goal. Under the plan, every participating named executive officer other than our Chief Executive Officer had the opportunity to earn up to 100% of his or her base salary depending on performance of our company against the designated performance goal and performance of the executive against personal criteria determined at the beginning of 2008 by our Chief Executive Officer. Under separate terms approved by the Compensation Committee and contained in his employment agreement, our Chief Executive Officer participated in the plan with potential to earn a target incentive payment of 75% of his base salary, depending on achievement of the company’s target consolidated performance goal and pre-designated personal critical success factors, and a maximum of 150% of his base salary upon achievement of the maximum consolidated performance goal and the personal critical success factors.

     Performance Criteria. At the beginning of 2008, the Compensation Committee approved the following corporate consolidated operating income performance criteria for consideration of bonus awards to the named executive officers and other covered employees under the 2008 incentive plan (excluding one-time and special non-operating charges):

Threshold		Target		Maximum
Operating Income		Operating Income		Operating Income
$75.6 million		$100.8 million		$131.1 million

     For our 2008 incentive plan, the Committee selected consolidated operating income as the most appropriate performance goal because of its direct correlation with the interests of our stockholders and our overall company performance. The target level of operating income performance criteria reflected the target goal of our 2008 operating plan approved by the Board at the beginning of 2008. We viewed all three designated levels of operating income performance criteria as reasonable indications of achievement of value for our stockholders and company performance.

     The levels of performance criteria were also consistent with our 2008 earnings guidance. At the beginning of 2008, the consolidated operating income target of $100.8 million represented approximately $0.79 per diluted share in earnings, and the consolidated operating income threshold of $75.6 million represented approximately $0.58 per diluted share in earnings. Prior to the beginning of 2008, we announced that we anticipated our 2008 earnings to range between $0.70 and $0.85 per diluted share. As a result, our target annual incentive level represented achievement of the higher end of our earnings guidance range. In addition, we considered that achievement of the 2008 target operating income level would represent a 58% increase from our 2007 actual consolidated operating income of $63.9 million.

     Where an employee is primarily involved in a particular business unit, the financial performance criteria under our incentive plan are heavily weighted toward the operational performance of the employee’s business unit rather than consolidated company performance. All of our named executive officers have broader corporate responsibility; as a result, their performance goals are heavily weighted toward the consolidated performance of the company as a whole.

     During 2007, we achieved our consolidated corporate financial objectives under the 2007 incentive plan and we achieved most of the individual business unit financial objectives, resulting in more funds available under the plan for distribution to eligible executives and employees who had otherwise achieved high individual performance. For 2008, on a consolidated basis, excluding the impact of certain special non-recurring items, we earned approximately $68.5 million of operating income. Because on a consolidated basis we did not achieve our threshold or target financial objectives in 2008, the named executive officers and many other eligible executives and employees generally received reduced bonus payments pursuant to the plan. In awarding bonus payments for 2008, the Committee took into consideration our positive performance through the first nine months of 2008 and the unique economic circumstances that caused our performance to suffer during the last calendar quarter of 2008 and were unrelated to factors within our control. Our 2008 Summary Compensation Table below reflects the payments that our named executive officers received under our 2008 incentive plan. Because certain business units exceeded their 2008 financial objectives, employees primarily involved in those business units received larger bonus payments under the plan.

     In February 2009, the Compensation Committee approved our 2009 annual incentive plan. The general structure of our 2009 annual incentive plan is similar to our 2008 incentive plan, except that the performance criteria under the 2009 plan will be focused on achievement of Adjusted EBITDA (net income before net interest expense, taxes, depreciation and amortization and other factors) rather than operating income. Management and the Committee concluded that, in the current depressed industry and economic environment, it was important for ION to encourage achievement of cash flow and Adjusted EBITDA and therefore the Committee approved performance criteria based on Adjusted EBITDA for 2009 bonus awards to the named executive officers and other covered employees under our 2009 incentive plan. The particular performance goals designated under our 2009 plan reflect our confidential strategic plans, and cannot be disclosed at this time because it would provide our competitors with confidential information regarding our market and segment outlook and strategies. We are currently unable to determine how difficult it will be for our company to meet the designated performance goals under our 2009 plan. Generally, the Committee attempts to establish the threshold, target and maximum levels such that the relative difficulty of achieving each level is approximately consistent from year to year.

     2009 Variable Payment Plan. As described above, the current global recession and decline in oil and gas prices resulted in a significant decline in our business and, as a result, in April 2009 we implemented a base salary reduction program in an effort to reduce our operating costs. Under the salary reduction program, base salaries for all employees were reduced by certain percentages, depending on the level of the employee. The salary reduction program will remain in effect until management and the Board determine that improvements in our operating results warrant the end of the program.

     In April 2009, the Compensation Committee approved the 2009 Variable Payment Plan (the “Variable Plan”).

All persons who were employed, either full-time or part-time, by us on the Variable Plan effective date are eligible to participate in the plan, including all executive officers. Under the Variable Plan, upon our company achieving a predetermined level of consolidated Adjusted EBITDA (net income before net interest expense, taxes, depreciation and amortization and other factors) during 2009 and management and the Compensation Committee’s determination that the company has sufficient levels of liquidity to make the plan payments, participating employees may receive a plan payment equal to an amount of up to 110% of the aggregate sum resulting from subtracting (a) the respective employee’s reduced base salary amount per pay period received by the employee during the period from the Variable Plan’s effective date to December 31, 2009, from (b) the employee’s base salary amount per pay period immediately before the Variable Plan’s effective date. If an eligible participating employee does not receive a full 110% payment under the Variable Plan, the employee will receive a supplemental allotment of extra vacation days equal in value to the plan shortfall. Employees must be active and on ION’s payroll at the time of actual payment of awards under the Variable Plan in order to be eligible to receive an award under this plan. Performance under the Variable Plan is measured on the fiscal (calendar) 2009 year. Eligibility under this plan is subject to management’s discretion and all awards under the plan are subject to management’s discretion and the approval of the Compensation Committee. Any monetary awards to be made under the Variable Plan will be paid prior to payment of any awards under the 2009 annual incentive plan and all payments to be made under the Variable Plan will be factored into and reflected in the company’s financial results prior to the consideration of results for, and any actual payments under, the 2009 annual incentive plan.

     The particular level of Adjusted EBITDA performance goal designated under the Variable Plan reflects our confidential strategic plans, and cannot be disclosed at this time because it would provide our competitors with confidential information regarding our market and segment outlook and strategies. We are currently unable to determine how difficult it will be for our company to meet the designated performance goal under the Variable Plan.

Long-Term Stock-Based Incentive Compensation

     We have structured our long-term incentive compensation to provide for an appropriate balance between rewarding performance and encouraging employee retention and stock ownership. There is no pre-established policy or target for the allocation between either cash or non-cash or short-term and long-term incentive compensation; however, long-term incentives comprise a large portion of the total compensation package for executive officers and key employees. As reflected in our 2008 Summary Compensation Table below, the long-term incentives received by each of our named executive officers as a percentage of their respective total compensation during 2008 were as follows: Mr. Peebler — 47%; Mr. Hanson — 57%; Mr. Hollis — 53%; Mr. Koid — 60%; Mr. Ledet — 64% and Mr. Friedemann — 50%. Because certain of our named executive officers received special stock awards as the result of job promotions during the year and because the value of certain equity awards included in the 2008 Summary Compensation Table is based on the FAS 123R value and includes amounts from awards granted prior to 2008, the above percentages may not be indicative of the true percentage of long-term incentive awards to total executive compensation.

     For 2008, there were four forms of long-term incentives utilized for executive officers and key employees: stock options, restricted stock, restricted stock units and stock appreciation rights. For 2009, we have recommended that stock options, restricted stock and restricted stock units be the only forms of long-term equity-based incentives to be utilized for executive officers and key employees. Our long-term incentive plans have provided the principal method for our executive officers to acquire equity or equity-linked interests in our company.

     Of all stock option or restricted stock employee awards made by ION during 2008, 86% were in the form of stock options and 14% were in the form of restricted stock or restricted stock units.

     Stock Options. Under our equity plans, stock options may be granted having exercise prices equal to either the closing price of our stock on the date before the date of grant or the average of the high and low sale prices of our stock on the date of grant, depending on the terms of the particular stock option plan that governs the award. In any event, all awards of stock options are made at or above the market price at the time of the award. The Compensation Committee will not grant stock options having exercise prices below the market price of our stock on the date of grant, and will not reduce the exercise price of stock options (except in connection with adjustments to reflect recapitalizations, stock or extraordinary dividends, stock splits, mergers, spin-offs and similar events, as required by the relevant plan) without the consent of our stockholders. Our stock options generally vest ratably over four years, based on continued employment. Prior to the exercise of an option, the holder has no rights as a stockholder with respect to the shares subject to such

option, including voting rights and the right to receive dividends or dividend equivalents. New option grants normally have a term of ten years.

     The purpose of stock options is to provide equity compensation with value that has been traditionally treated as entirely at-risk, based on the increase in our stock price and the creation of stockholder value. Stock options also allow our executive officers and key employees to have equity ownership and to share in the appreciation of the value of our stock, thereby aligning their compensation directly with increases in stockholder value. Stock options only have value to their holder if the stock price appreciates in value from the date options are granted.

     Stock option award decisions are generally based on past business and individual performance. In determining the number of options to be awarded, we also consider the grant recipient’s qualitative and quantitative performance, the size of stock option and other stock based awards in the past, and expectations of the grant recipient’s future performance. In 2008, a total of 253 employees received option awards, covering 2,296,950 shares of common stock. In 2008, the named executive officers received option awards for a total of 430,000 shares, or approximately 19% of the total options awarded in 2008.

     Restricted Stock and Restricted Stock Units. We use restricted stock and restricted stock units to focus executives on our long-term performance and to help align their compensation more directly with stockholder value. Vesting of restricted stock and restricted stock units typically occurs ratably over three years, based solely on continued employment of the recipient-employee. During 2005 and 2006, however, we utilized performance requirements for the vesting of some of our long-term incentive grants awarded to executives and key employees. The performance requirements utilized during 2005 and 2006 involved achievement of a business unit’s internal financial goals or completion of a specific project. In certain cases, the performance requirements were not satisfied, causing a forfeiture of the grant. In 2008, 206 employees received restricted stock or restricted stock unit awards, covering an aggregate of 388,883 shares of restricted stock and shares underlying restricted stock units. The named executive officers received awards totaling 112,445 shares of restricted stock in 2008, or approximately 29% of the total restricted stock awarded in 2008.

     Awards of restricted stock units have been made to certain of our foreign employees in lieu of awards of restricted stock. Restricted stock units provide certain tax benefits to our foreign employees as the result of foreign law considerations, so we expect to continue to award restricted stock units to certain foreign employees for the foreseeable future.

     Stock Appreciation Rights. In 2008, we awarded cash-settled stock appreciation rights to Mr. Hollis and Mr. Hanson as a special grant in lieu of grants of stock options to provide further emphasis on our long-term performance and to further align their compensation more directly with stockholder value. Vesting of all of the stock appreciation rights awarded to Messrs. Hollis and Hanson occurs after three years, based solely on their continued employment. During 2008, we also awarded stock appreciation rights to Mr. Ledet in connection with his severance package and his agreement to provide consulting services to the company after his termination of employment.

     The Compensation Committee intends to review both the annual incentive compensation program and the long-term incentive program annually to ensure that their key elements continue to meet the objectives described above.

     Approval and Granting Process. As described above, the Compensation Committee reviews and approves all stock option, restricted stock, restricted stock unit and stock appreciation right awards made to executive officers, regardless of amount. With respect to equity compensation awarded to employees other than executive officers, the Committee reviews and approves all grants of restricted stock, stock options and restricted stock units above 5,000 shares, generally based upon the recommendation of our Chief Executive Officer. Committee approval is required for any grant to be made to an executive officer in any amount. The Committee has granted to our Chief Executive Officer the authority to approve grants to any employee other than an executive officer of (i) up to 5,000 shares of restricted stock and (ii) stock options for not more than 5,000 shares. Our Chief Executive Officer is also required to provide a report to the Committee of all awards of options and restricted stock made by him under this authority. We believe that this policy is beneficial because it enables smaller grants to be made more efficiently. This flexibility is particularly important with respect to attracting and hiring new employees, given the increasingly competitive market for talented and experienced technical and other personnel in locales in which our employees work.

     All grants of restricted stock, restricted stock units, stock options and stock appreciation rights to employees or directors are granted on one of four designated quarterly grant dates during the year: March 1, June 1, September 1 or December 1. The Compensation Committee approved these four dates because they are not close to any dates that would normally be anticipated to contain earnings announcements or other announcements of material events. For an award to a current employee, the grant date for the award is the first designated quarterly grant date that occurs after approval of the award. For an award to a newly hired employee who is not yet employed by us at the time the award is approved, the grant date for the award is the first designated quarterly grant date that occurs after the new employee commences work. We believe that this process of fixed quarterly grant dates is beneficial because it serves to remove any perception that the grant date for an award could be capable of manipulation or change for the benefit of the recipient. In addition, having all grants occur on a maximum of four days during the year simplifies certain fair value accounting calculations related to the grants, thereby minimizing the administrative burden associated with tracking and calculating the fair values, vesting schedules and tax-related events upon vesting of restricted stock and also lessening the opportunity for inadvertent calculation errors.

     With the exception of significant promotions, new hires or unusual circumstances, we generally make most awards of equity compensation on December 1 of each year. This date was selected because (i) it enables us to consider individual performance eleven months into the year, (ii) it simplifies the annual budget process by having the expense resulting from the equity award occur late in the year, (iii) the date is approximately three months before the date that we normally pay any annual incentive bonuses and (iv) generally speaking, December 1 is not close to any dates that would normally be anticipated to contain earnings announcements or other announcements of material events.

     We do not have in effect any policies regarding the adjustment or recovery of awards or payments made by us in the event that any relevant performance measures of our company on which the awards or payments may be based, are subsequently restated or otherwise adjusted in a manner that would reduce the size of the award or payment.

Personal Benefits, Perquisites and Employee Benefits

     When analyzing the total compensation received by our Chief Executive Officer and other executives, the Compensation Committee also considers whether the executives should be provided additional compensation in the form of perquisites through the availability of benefits that are convenient for the executives to use when faced with the demands of their positions. Our executives have concluded that most perquisites traditionally offered to executives of similarly-sized companies are unnecessary for our company. As a result, benefits, perquisites and any other similar personal benefits offered to executive officers are substantially the same as those offered to our general salaried employee population. These benefits include access to medical and dental insurance, life insurance, disability insurance, vision plan, charitable gift matching (up to designated limits), 401(k) plan, flexible spending accounts for healthcare and dependent care, and other customary employee benefits. We have in the past provided all employees with a company match of certain levels of 401(k) contributions; however, as part of our cost-cutting measures taken as a result of the economic recession and decline in oil and gas prices, in April 2009, we temporarily discontinued the company match for all employees, including executive officers. Business-related relocation benefits are generally reimbursed but are individually negotiated when they occur. We intend to continue applying our general policy of not providing specific personal benefits and perquisites to our executives; however, we may, in our discretion, revise or add to any executive’s personal benefits and perquisites if we deem it advisable.

Indemnification of Directors and Executive Officers

     Our Bylaws require us to indemnify our directors and employees (including our executive officers) in connection with any legal action brought against them by reason of the fact that they are or were a director, officer, employee or agent of our company, to the full extent permitted by law. Our Bylaws also provide, however, that no such obligation to indemnify exists as to proceedings initiated by an employee or director against us or our directors unless (a) it is a proceeding (or part thereof) initiated to enforce a right to indemnification or (b) was authorized or consented to by our Board of Directors.

     In 2002, we also entered into indemnity agreements with certain of our outside directors that provide for us to indemnify the director in connection with any proceeding in which the director is involved by reason of the fact that the director is or was a director of the company. In order to be indemnified under these agreements, the director must have

acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the company and, in the case of a criminal proceeding, had no reasonable cause to believe that his or her conduct was unlawful.

     As discussed below, we have also entered into employment agreements with certain of our executive officers that provide for us to indemnify the executive to the fullest extent permitted by our Certificate of Incorporation and Bylaws. The agreements also provide that we will provide the executive with coverage under our directors’ and officers’ liability insurance policies to the same extent as provided to our other executives.

Stock Ownership Requirements; Hedging Policy

     We believe that broad-based stock ownership by our employees (including our executive officers) enhances our ability to deliver superior stockholder returns by increasing the alignment between the interests of our employees and our stockholders. Accordingly, the Board has adopted stock ownership requirements applicable to each of our senior executives, including our named executive officers. The policy requires each executive to retain direct ownership of at least 50% of all shares of our company’s stock received upon exercise of stock options and vesting of awards of restricted stock or restricted stock units until the executive owns shares with an aggregate value equal to the following multiples of the executive’s annual base salary:

President and Chief Executive Officer — 4x
Executive Vice President — 2x
Senior Vice President — 1x

     In recommending these requirements to the Board for adoption, the Governance Committee considered our historical grant practices, historical retention practices for senior executives, and value of current holdings by our senior executives, and concluded that this policy would meet our desired objectives. As of the date of this proxy statement, all of our senior executives were in compliance with the stock ownership requirements.

     We do not permit any of our executive officers or directors to enter into any derivative or hedging transactions on our stock, including short sales, market options, equity swaps and similar instruments.

Impact of Regulatory Requirements on Compensation

     The financial reporting and income tax consequences to our company of individual compensation elements are important considerations for the Compensation Committee when it is analyzing the overall level of compensation and the mix of compensation among individual elements. Under Section 162(m) of the Internal Revenue Code and the related federal treasury regulations, we may not deduct annual compensation in excess of $1 million paid to certain employees — generally our Chief Executive Officer and our four other most highly compensated executive officers — unless that compensation qualifies as “performance-based” compensation. Overall, the Committee seeks to balance its objective of ensuring an effective compensation package for the executive officers with the need to maximize the immediate deductibility of compensation — while ensuring an appropriate (and transparent) impact on reported earnings and other closely followed financial measures.

     In making its compensation decisions, the Committee has considered the limit of deductibility within the requirements of Internal Revenue Code Section 162(m) and its related Treasury regulations. As a result, the Committee has designed much of the total compensation packages for the executive officers to qualify for the exemption of “performance-based” compensation from the deductibility limit. However, the Committee does have the discretion to design and use compensation elements that may not be deductible within the limitations under Section 162(m), if the Committee considers the tax consequences and determines that those elements are in our best interests. To maintain flexibility in compensating executive officers in a manner designed to promote varying corporate goals, we have not adopted a policy that all compensation must be deductible.

     Certain payments to our named executive officers under our 2008 annual incentive plan (as well as under our Variable Plan) may not qualify as performance-based compensation under Section 162(m) because the awards are calculated and paid in a manner that may not meet the requirements under Section 162(m) and the related Treasury

regulations. Given the rapid changes in our business during 2008 and those that we foresee for the remainder of 2009, we believe that we are better served in implementing a plan that provided for adjustments and discretionary elements for our senior executives’ incentive compensation for 2008 and 2009, rather than ensure that we implement all of the requirements and limitations under Section 162(m) into these incentive plans.

     For accounting purposes, we apply the guidance in FAS 123R to record compensation expense for our equity-based compensation grants. FAS 123R is used to develop the assumptions necessary and the model appropriate to value the awards as well as the timing of the expense recognition over the requisite service period, generally the vesting period, of the award.

     Executive officers will generally recognize ordinary taxable income from stock option awards when a vested option is exercised. We generally receive a corresponding tax deduction for compensation expense in the year of exercise. The amount included in the executive officer’s wages and the amount we may deduct is equal to the common stock price when the stock options are exercised less the exercise price, multiplied by the number of stock options exercised. We do not pay or reimburse any executive officer for any taxes due upon exercise of a stock option. We have not historically issued any tax-qualified incentive stock options under Section 422 of the Internal Revenue Code.

     Executives will generally recognize taxable ordinary income with respect to their shares of restricted stock at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant). Restricted stock unit awards are generally subject to ordinary income tax at the time of payment or issuance of unrestricted shares of stock. We are generally entitled to a corresponding federal income tax deduction at the same time the executive recognizes ordinary income.

COMPENSATION COMMITTEE REPORT

     The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this proxy statement with management of ION. Based on such review and discussions, the Compensation Committee has recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated into ION’s annual report on Form 10-K for the year ended December 31, 2008.

Special Note on Current Stock Market Value Compared with Compensation Cost in Summary Compensation Table

     The amounts in the “Stock Awards” and “Option Awards” columns reflect the value of restricted stock and stock options and stock appreciation rights, respectively, based on the compensation cost of all awards with respect to the 2008 year computed in accordance with FAS 123R for financial statement reporting purposes (excluding any impact of assumed forfeiture rates). As a result, the amounts shown above include amounts from awards granted prior to 2008. More notably, the values shown in the above table have no relation to the current market price of ION stock. On February 20, 2009, the closing sales price per share of ION common stock on the NYSE was $1.19. Every stock option and stock appreciation right included in the Summary Compensation Table has an exercise price higher than ION’s closing market price on February 20, 2009. As a result, every stock option and stock appreciation right included in the above table currently has no realizable monetary value to the holder, despite the accounting valuations reflected in the table. Likewise, the cost amounts included in the “Stock Awards” column were based on market prices of ION stock at the time of grant, which in every case were significantly higher than current market prices.

Discussion of Summary Compensation Table

     Stock Awards Column. All of the amounts in the “Stock Awards” column reflect the value of shares of restricted stock granted under our 2000 Restricted Stock Plan, 2004 Long-Term Incentive Plan, and April 2005 Inducement Equity Program. While unvested, a holder of restricted stock is entitled to the same voting and dividend rights as all other holders of common stock. In each case, unless stated otherwise below, the awards of shares of restricted stock vest in one-third increments each year, over a three-year period. The values contained in the column are based on the compensation cost of all awards with respect to fiscal 2008 computed in accordance with FAS 123R for financial statement reporting purposes (excluding any impact of assumed forfeiture rates) and therefore include amounts from awards granted prior to 2008. For a discussion of valuation assumptions utilized in all reported restricted stock award and option valuations, see Note 13 to our Audited Consolidated Financial Statements included in our annual report on Form 10-K for the year ended December 31, 2008. In addition to the grants and awards in 2008 described in the “2008 Grants of Plan-Based Awards” table below:

•

Pursuant to his employment agreement, on March 1, 2007, Mr. Peebler received:

	•		an award of 32,560 shares of restricted stock, which is equal to $435,000 (the amount of cash incentive plan compensation that Mr. Peebler earned for fiscal 2006) divided by $13.36, which was the average of the closing sales price per share on the NYSE of our shares of common stock for the last ten business days of 2006. The shares of restricted stock vested on March 1, 2009.
	•		an award of 37,425 shares of restricted stock, which is equal to the amount of Mr. Peebler’s annual base salary as of March 1, 2007, divided by $13.36. The shares of restricted stock will vest on March 1, 2010. See “Employment Agreements—Robert P. Peebler” below.

	•		Mr. Hollis received an award of 5,000 shares of restricted stock in May 2006; 15,000 shares of restricted stock in September 2006; 10,000 shares of restricted stock in December 2006; and 15,000 shares of restricted stock in December 2007.
	•		Mr. Hanson received an award of 75,000 shares of restricted stock in May 2006 and 15,000 shares of restricted stock in December 2007.
	•		Mr. Koid received an award of 10,000 shares of restricted stock in September 2006 and 30,000 shares of restricted stock in December 2007.
	•		Mr. Friedemann received an award of 10,000 shares of restricted stock in September 2006 and 10,000 shares of restricted stock in December 2007.
	•		Mr. Ledet received an award of 8,000 shares of restricted stock in September 2006 and 20,000 shares of restricted stock in December 2007. Mr. Ledet’s employment with ION ended on December 1, 2008. As a result of the termination of his employment, 15,998 shares of restricted stock held by Mr. Ledet were forfeited on December 1, 2008.

     Option Awards Column. All of the amounts shown in the “Option Awards” column reflect stock options and cash-settled stock appreciation rights (“SARs”) granted under our 2000 Long-Term Incentive Plan, 2003 Stock Option Plan, 2004 Long-Term Incentive Plan and April 2005 Inducement Equity Program and our Stock Appreciation Rights Plan, respectively. In each case, unless stated otherwise below, the options vest 25% each year over a four-year period and the SARs will vest on December 1, 2011. The values contained in the Summary Compensation Table are based on the compensation cost of all awards with respect to fiscal 2008 computed in accordance with FAS 123R for financial statement reporting purposes (excluding any impact of assumed forfeiture rates) and therefore include amounts from awards granted prior to 2008. All of the exercise prices for the options and SARs equal or exceed the fair market value per share of ION common stock on the date of grant. In addition to the grants and awards in 2008 described in the “2008 Grants of Plan-Based Awards” table below:

	•		In September 2004, Mr. Hollis was granted an award of options to purchase 40,000 shares of our common stock for an exercise price of $9.84 per share; in August 2005, he was granted options to purchase 15,000 shares at $7.31 per share; in May 2006, he was granted options to purchase 15,000 shares at $10.17 per share; in September 2006, he was granted options to purchase 45,000 shares at $9.97 per share; in December 2006, he was granted options to purchase 25,000 shares at $10.89 per share; and in December 2007, he was granted options to purchase 50,000 shares at $15.43 per share;.
	•		In May 2006, Mr. Hanson was granted an award of options to purchase 75,000 shares of our common stock for an exercise price of $8.73 per share; in September 2006, he was granted options to purchase 20,000 shares at $9.97 per share; and in December 2007, he was granted options to purchase 15,000 shares at $15.43 per share.
	•		We entered into an employment inducement stock option agreement with Mr. Koid in April 2005, whereby he was granted an award of options to purchase 55,000 shares of our common stock for an exercise price of $6.49 per share as a material inducement to joining ION. In August 2005, Mr. Koid was granted an award of options to purchase 40,000 shares of our common stock for an exercise price of $7.31 per share; in September 2006, he was granted options to purchase 35,000 shares at $9.97 per share; and in December 2007, he was granted options to purchase 70,000 shares at $15.43 per share.
	•		In September 2004, Mr. Friedemann was granted an award of options to purchase 60,000 shares of our common stock for an exercise price of $9.84 per share; in September 2005, he was granted options to purchase 40,000 shares at $7.31 per share; in September 2006, he was granted options to purchase 40,000 shares at $9.97 per share; and in December 2007, he was granted options to purchase 40,000 shares at $15.43 per share.
	•		In September 2004, Mr. Ledet was granted an award of options to purchase 25,000 shares of our common stock at an exercise price of $9.84 per share; in May 2005, he was granted options to purchase 40,000 shares at $6.20 per share; in September 2006, he was granted options to purchase 25,000 shares at $9.97 per share; and in December 2007, he was granted options to purchase 95,000 shares at $15.43. Mr. Ledet’s employment with ION ended on December 1, 2008. As a result of the termination of his employment, unvested options to purchase 93,750 shares of our common stock held by Mr. Ledet were forfeited on December 1, 2008. On December 1, 2008, Mr. Ledet entered into a Consulting Agreement with ION, under which Mr. Ledet agreed to provide consulting services to ION for a period of two years. In connection with the Consulting Agreement, Mr. Ledet agreed to the termination on December 1, 2008, of a total of 141,250 vested stock options held by him.

     All payments of non-equity incentive plan compensation reported for 2008 were made in February 2009 with regard to the 2008 fiscal year and were paid pursuant to our 2008 incentive plan.

     We do not sponsor for our employees (i) any defined benefit or actuarial pension plans (including supplemental plans), (ii) any non-tax-qualified deferred compensation plans or arrangements or (iii) any nonqualified defined contribution plans.

     Our general policy is that our executive officers do not receive any executive “perquisites,” or any other similar personal benefits that are different from what our salaried employees are entitled to receive. ION provides the named executive officers with certain group life, health, medical and other non-cash benefits generally available to all salaried employees, which are not included in the “All Other Compensation” column in the Summary Compensation Table pursuant to SEC rules. Except as noted below, the amounts shown in the “All Other Compensation” column consist of employer matching contributions to ION’s 401(k) plan. In 2008, the 401(k) accounts for each of the named executive officers received the following matching contributions from the company: $3,206.72 for Mr. Peebler; $6,653.79 for Mr. Hollis; $7,749.97 for Mr. Hanson; $3,490.41 for Mr. Koid; $4,145.08 for Mr. Friedemann; and $7,507.14 for Mr. Ledet.

     In connection with his termination of employment on December 1, 2008, Mr. Ledet and ION entered into a severance agreement pursuant to which Mr. Ledet is entitled to receive cash payments in an aggregate amount equal to

$468,000, payable in installments over an 18-month period. The amount shown in the “Salary” column for 2008 includes a $10,800 severance payment that Mr. Ledet received in December 2008.

Employment Agreements

     We enter into employment agreements with senior officers, including some of the named executive officers, when the Compensation Committee determines that an employment agreement is desirable for us to obtain a measure of assurance as to the executive’s continued employment in light of prevailing market competition for the particular position held by the executive officer, or where the Committee determines that an employment agreement is necessary and appropriate to attract an executive in light of market conditions, the prior experience of the executive or practices at ION with respect to other similarly situated employees. As of December 31, 2008, the only named executive officers with employment agreements were Mr. Peebler and Mr. Hanson. In January 2009, we entered into an employment agreement with Mr. Hollis, effective retroactively to December 1, 2008, the date that Mr. Hollis was appointed as our President and Chief Operating Officer.

     The following discussion describes the material terms of the employment agreements with Messrs. Peebler, Hanson and Hollis:

Robert P. Peebler

     Our employment agreement with Mr. Peebler, dated March 31, 2003, provides that Mr. Peebler will serve as President and Chief Executive Officer for a five-year term, unless sooner terminated. We amended Mr. Peebler’s employment agreement in September 2006, February 2007, August 2007 and January 2009, to extend the term to December 31, 2011, and to make certain other changes. This description reflects Mr. Peebler’s employment agreement as so amended, except where the context requires otherwise.

     Under the agreement, Mr. Peebler is entitled to an annual base salary of at least $500,000, and to participate in all of our employee benefit plans available to senior executives at a level commensurate with his position. Mr. Peebler’s annual base salary was increased to $525,000 in September 2007 and to $575,000 in September 2008. As part of a salary reduction program implemented by the company in April 2009, Mr. Peebler agreed to a reduction of his annual base salary to $506,000.

     Mr. Peebler was not guaranteed an annual bonus under his original 2003 employment agreement, but his 2006 amendment provides that Mr. Peebler will be eligible to participate in our annual incentive plan for 2006 and each full year thereafter, with target incentive plan bonus at 75% of his base salary and with maximum incentive plan bonus at 150% of his base salary. His annual bonus will be earned upon achievement of our consolidated operating income performance targets applicable to the senior leadership bonus plan for the relevant year, and Mr. Peebler’s critical success factors as determined in advance by the Compensation Committee.

     Under his employment agreement, Mr. Peebler received a grant in 2003 of an option to purchase 1,325,000 shares of our common stock at $6.00 per share, which exercise price exceeded the market price of our shares on the date of grant by 60% (at March 31, 2003, the date of his grant, the closing sales price per share of our common stock on the NYSE was $3.60). Mr. Peebler’s amended employment agreement provides that he is entitled to receive (a) in 2007, an award of shares of restricted common stock based on the amount of the annual incentive plan bonus earned by him for

2006, vesting on the date that is the second anniversary of the date of the award; (b) in 2007, an award of shares of restricted common stock equivalent in value to his annual base salary, vesting on the date that is the third anniversary of the date of the award; and (c) in years following 2007 through the end of the term of his agreement, an award of shares of restricted common stock based on the amount of the annual incentive plan bonus, if any, earned by Mr. Peebler for the preceding year, vesting on the date that is the second anniversary of the date of the award, and additional stock options as may be determined by the Compensation Committee. The shares of restricted common stock will be subject to restrictions on disposition and, during the period that the shares of restricted common stock are unvested, Mr. Peebler will be entitled to the same voting and dividend rights as all other holders of common stock.

     We may at any time terminate our employment agreement with Mr. Peebler for “cause” if Mr. Peebler (i) willfully and continuously fails to substantially perform his obligations, (ii) willfully engages in conduct materially and demonstrably injurious to our property or business (including fraud, misappropriation of funds or other property, other willful misconduct, gross negligence or conviction of a felony or any crime involving moral turpitude) or (iii) commits a material breach of the agreement. In addition, we may at any time terminate the agreement if Mr. Peebler suffers permanent and total disability for a period of at least 180 consecutive days, or if Mr. Peebler dies. Mr. Peebler may terminate his employment agreement for “good reason” if we breach any material provision of the agreement, we assign to Mr. Peebler any duties materially inconsistent with his position, we remove him from his current office, materially reduce his duties, functions, responsibilities or authority, or take other action that results in a diminution in his office, position, duties, functions, responsibilities or authority, or we relocate his workplace by more than 30 miles.

R. Brian Hanson

     Our employment agreement with Mr. Hanson became effective in May 2006. We amended Mr. Hanson’s employment agreement in August 2007 and in December 2008. This description reflects Mr. Hanson’s employment agreement as so amended.

     The agreement provides for Mr. Hanson to serve as our Executive Vice President and Chief Financial Officer for an initial term of three years, with automatic two-year renewals thereafter. Any change of control of our company will cause the remaining term of Mr. Hanson’s employment agreement to automatically adjust to two years, commencing on the effective date of the change of control.

     The agreement provides for Mr. Hanson to receive an initial base salary of $275,000 per year and be eligible to receive an annual performance bonus under our incentive compensation plan, with target plan incentive at 50% of his annual base salary and an opportunity to earn up to 100% of his annual base salary. Mr. Hanson’s annual base salary was increased to $285,000 in September 2006, to $300,000 in September 2007 and to $327,000 in September 2008. As part of a salary reduction program implemented by the company in April 2009, Mr. Hanson agreed to a reduction of his annual base salary to $287,760.

     Under the agreement, in May 2006 Mr. Hanson was granted 75,000 shares of restricted common stock and options to purchase 75,000 shares of our common stock. The agreement also provides that Mr. Hanson is entitled to receive (a) in 2010, an award of shares of restricted common stock based on the amount of the annual incentive plan bonus earned by him for 2009; and (b) in years following 2010 through the end of the term of his agreement, an award of shares of restricted common stock based on the amount of the annual incentive plan bonus, if any, earned by Mr. Hanson with respect to the preceding year. The shares of restricted common stock will be subject to restrictions on

disposition and will vest on the date that is the third anniversary date of the date of the award. During the period that the shares of restricted common stock are unvested, Mr. Hanson will be entitled to the same voting and dividend rights as all other holders of common stock. In the agreement, we also agreed to indemnify Mr. Hanson to the fullest extent permitted by our Certificate of Incorporation and Bylaws, and to provide him coverage under our directors’ and officers’ liability insurance policies to the same extent as other company executives.

     For a discussion of the provisions of Mr. Hanson’s employment agreement regarding compensation to Mr. Hanson in the event of our change of control or his termination by us without cause or by him for good reason, see “—Potential Payments Upon Termination or Change of Control — R.

     Mr. Hollis will be entitle to receive, on an annual basis during the term of his employment agreement, an award of shares of restricted common stock under the terms of our 2004 Long-Term Incentive Plan. Each award will have a value equal to the amount of the annual incentive plan bonus, if any, earned by Mr. Hollis with respect to our most recently completed fiscal year. This arrangement will take effect beginning with the annual incentive plan bonus, if any, earned by Mr. Hollis with respect to fiscal 2009. The shares of restricted common stock will be subject to restrictions on disposition and will vest on the date that is the third anniversary date of the date of the award.
