When are stockholder proposals due for next year’s annual meeting?

If you wish to submit a proposal to be considered for inclusion in Gran Tierra’s proxy materials next year, your proposal must be submitted in writing by December 31, 2009to Martin Eden at 300, 611-10th Avenue, S.W., Calgary, Alberta, T2R 0B2, Canada; provided, however, that if our 2010 annual meeting of stockholders is held before May 17, 2010 or after July 16, 2010, then the deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2010 annual meeting of stockholders.  If you wish to submit a proposal that is not to be included in Gran Tierra’s proxy materials next year or to nominate a director next year, you must do so between March 18, 2010 and April 17, 2010, unless our 2010 annual meeting of stockholders is not held between May 17, 2010 and August 15, 2010, in which case notice must be delivered to Gran Tierra not earlier than the 90th day prior to the meeting and not later than the later of the 60th day prior to the meeting or the 10th day following the day on which Gran Tierra makes its first public announcement of the meeting date. You are also advised to review our Bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count “For” and “Withhold” and, with respect to proposals other than the election of directors, “Against” votes, abstentions and broker non-votes.  Abstentions and broker non-votes have no effect and will not be counted towards the vote total for any proposal except for Proposal 2.  For Proposal 2, abstentions and broker non-votes will have the same effect as “Against” votes.

What are “broker non-votes”?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the sharesas to how to vote on matters deemed “non-routine.”  Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares.  If the beneficial owner does not provide voting instructions, the broker or nomineecan still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters.  Under the rules and interpretations of the New York Stock Exchange (“NYSE”), “non-routine” matters are generally those involving a contest or a matter that may substantially affect the rights or privileges of shareholders, such as mergers or shareholder proposals.

How many votes are needed to approve each proposal?

Ø For the election of directors, the seven nominees receiving the most “For” votes (from the holders of votes of shares present in person or represented by proxy and entitled to vote on the election of directors) will be elected.  Only votes “For” will affect the outcome;

8.

Ø To be approved, Proposal 2, the amendment to Gran Tierra’s Articles of Incorporation to increase the number of shares of Gran Tierra’s common stock authorized for issuance, must receive “For” votes from the holders of shares of Gran Tierra’s common stock, Goldstrike Exchangeable Shares, and Solana Exchangeable Shares entitling them to exercise at least a majority of the combined voting power of the total number of outstanding shares of Gran Tierra’s common stock, Goldstrike Exchangeable Shares, and Solana Exchangeable Shares.  As a result, abstentions and broker non-votes will have the same effect as “Against” votes; and

Ø To be approved, Proposal 3, the ratification of the selection by the Audit Committee of the Board of Deloitee & Touche LLP as our independent auditors for our fiscal year ended December 31, 2009, must receive more “For” votes than “Against” votes.  Abstentions and broker non-votes will have no effect.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting.  A quorum will be present if stockholders holdingoutstanding shares of Gran Tierra’s capital stock representing at least a majority of the total number of votes are present at the meeting in person or represented by proxy.  On the record date, there were 238,395,553 votes that could be cast.  Those votes were represented by 203,258,613 shares of common stock outstanding and entitled to vote and 35,136,940 shares of common stock issuable upon exchange of the Exchangeable Shares and therefore entitled to vote through the one share of Special A Voting Stock and one share of Special B Voting Stock.  Thus, holders of outstanding shares representing at least 119,197,777 votes must be present in person or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting.  Abstentions and broker non-votes will be counted towards the quorum requirement.  If there is no quorum, the Chairman of the meeting or the holders of a majority of shares present at the meeting in person or represented by proxy must adjourn the meeting to another date.

How can I find out the results of the voting at the annual meeting?

Preliminary voting results will be announced at the annual meeting.  Final voting results will be published in our quarterly report on Form 10-Q for the second quarter ending June 30, 2009.

What proxy materials are available on the internet?

The proxy statement and annual report to stockholders are available at www.grantierra.com.

Proposal 1

Election Of Directors

Gran Tierra’s Board of Directors consists of seven directors.  There are seven nominees for director this year.  Each director to be elected and qualified will hold office until the next annual meeting of stockholders and until his successor is elected, or, if sooner, until the director’s death, resignation or removal.  Each of the nominees listed below, except for Mr. Price and Mr. Antony, is currently a director of Gran Tierra who was previously elected by the stockholders.  Pursuant to the terms of the Arrangement Agreement, dated July 28, 2008 and last amended on October 9, 2008, by and between Gran Tierra, Gran Tierra Exchangeco Inc., and Solana (the “Arrangement Agreement”), Mr. Price and Mr. Antony were designated to serve on Gran Tierra’s Board of Directors, effective November 14, 2008.  Prior to the Arrangement Agreement, Mr. Price was Solana’s President, Chief Executive Officer, and a member of Solana’s board of directors, and Mr. Antony was the Chairman of Solana’s board of directors.  It is Gran Tierra’s policy to invite nominees for directors to attend the annual meeting.  Four out of five of the then current directors attended the 2008 Annual Meeting of Stockholders.

Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors.  The seven nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the sevennominees named below.  If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by Gran Tierra.  Each person nominated for election has agreed to serve if elected.  Gran Tierra’s management has no reason to believe that any nominee will be unable to serve.

Independence of The Board of Directors

Gran Tierra follows the listing standards of the NYSE Amex.  As required under the NYSE Amex listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors.  Gran Tierra’s Board of Directors consults with Gran Tierra’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in the NASDAQ and NYSE Amex listing standards, as in effect from time to time.

12.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his family members, and Gran Tierra, its senior management and its independent auditors, the Board has affirmatively determined that the following six of seven directors are independent directors within the meaning of the applicable NYSE Amex listing standards: Messrs. Antony, Dawson, Johnson, Kirton, Price, and Scott.  In making this determination, the Board found that none of these directors or nominees for director had a material or other disqualifying relationship with Gran Tierra.  Dana Coffield, Gran Tierra’s President and Chief Executive Officer is not an independent director by virtue of his employment with Gran Tierra.

Meetings of The Board of Directors

The Board of Directors met twenty-onetimes during the last fiscal year.  Each Board member attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or sheserved, held during the portion of the last fiscal year for which he or she was a director or committee member, except that Mr. Scott attended one of the two meetings the Reserves Committee held in the last fiscal year.

Information Regarding Committees of the Board of Directors

The Board has four standing committees:an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, and a Reserves Committee.  The following table provides membership and meeting information for fiscal year 2008 for each committee of the Board:

(1) Ms. Smith resignedas a director effective March 27, 2008, and Mr. Kirton joined the Audit Committee on that date, also replacing Ms. Smith as Chairperson of the Audit Committee.

Below is a description of each committee of the Board of Directors.  Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities.

Audit Committee

The Audit Committee of the Board of Directors was established by the Board in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to oversee Gran Tierra’s corporate accounting and financial reporting processes and audits of its financial statements.  For this purpose, the Audit Committee performs several functions.  The Audit Committee reviews our financial reports and other financial information disclosed to the public, the government and various regulatory bodies, our system of internal accounting, our financial controls, and the annual independent audit of our financial statements.  The Audit Committee evaluates the performance of and assesses the qualifications of the independent auditors; determines and approves the engagement of the independent auditors; determines whether to retain or terminate the existing independent auditors or to appoint and engage new independent auditors; reviews and approves the retention of the independent auditors to perform any proposed permissible non-audit services; monitors the rotation of partners of the independent auditors on Gran Tierra’s audit engagement team as required by law; reviews and approves or rejects transactions between Gran Tierra and any related persons; confers with management and the independent auditors regarding the effectiveness of internal controls over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by Gran Tierra regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; and meets to review Gran Tierra’s annual audited financial statements and quarterly financial statements with management and the independent auditors, including a review of Gran Tierra’s disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”  The Audit Committee is composed of three directors: Jeffrey Scott, Verne Johnson, and Nicholas Kirton.  The Audit Committee met seventimes during the fiscal year.  The Audit Committee has adopted a written charter that is available to stockholders on Gran Tierra’s website at www.grantierra.com.

13.

The Board of Directors reviews the NYSE Amex listing standards definition of independence for Audit Committee members and has determined that all members of Gran Tierra’s Audit Committee are independent (as independence is currently established in Rule 803(a)(2) of the NYSE Amex listing standards).  Additionally each Audit Committee member has met the criteria for audit committee independence set forth in Rule 10A-3 promulgated pursuant to the Exchange Act.  The Board had determined that Nadine Smith, an independent director, qualified as an “audit committee financial expert” within the meaning of Item 407(d)(5) of Regulation S-K promulgated by the SEC, based on her experience overseeing and assessing the performance of companies with respect to the preparation and evaluation of financial statements, and that Mr. Kirton is an “audit committee financial expert” based on his past experience as a former KPMG partner.  

Report of the Audit Committee of the Board of Directors1

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2008 with management of Gran Tierra.  The Audit Committee has discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T.  The Audit Committee has also received the written disclosures and the letter from the independent accountants required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the audit committee concerning independence, and has discussed with the independent accountants the independent accountants’ independence.  Based on the foregoing, the Audit Committee has recommended to the Board of Directors that the audited financial statements be included in Gran Tierra’s Annual Report on Form 10-K for the fiscal year ended December 31, 2008.

Scott, Dawson, and Johnson.  All members of Gran Tierra’s Compensation Committee are independent (as independence is currently defined in Rule 803(a)(2) of the NYSE Amex listing standards).  The Compensation Committee met two times during the fiscal year. The Compensation Committee has adopted a written charter that is available to stockholders on Gran Tierra’s website at www.grantierra.com.

The Compensation Committee of the Board of Directors acts on behalf of the Board to review, recommend for adoption and oversee Gran Tierra’s compensation strategy, policies, plans and programs, including:

1 The material in this report is not “soliciting material” is not deemed "filed" with the Commission and is not to be incorporated by reference in any filing of Gran Tierra under the Securities Act or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

14.

· establishing corporate and individual performance objectives relevant to the compensation of Gran Tierra’s executive officers, directors, and other senior management, as appropriate, and evaluating performance in light of these stated objectives;

· establishing policies with respect to equity compensation arrangements;

· reviewing and approving the compensation and other terms of employment or service, including severance and change-in-control arrangements, of Gran Tierra’s Chief Executive Officer and the other executive officers; and

· reviewing and recommending to the Board for approval, modification or termination of Gran Tierra’s equity compensation plans, pension and profit-sharing plans, deferred compensation plans and other similar plans and programs, as well as administering such plans and programs.

The Compensation Committee also reviews with management Gran Tierra’s Compensation Discussion and Analysis and considers whether to recommend that it be included in proxy statements and other public filings.

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets at least once annually and with greater frequency if necessary.  The agenda for each meeting is usually developed by the chair of the Compensation Committee, in consultation with the Chief Executive Officer.  However, from time to time, various members of management and other employees as well as outside advisors or consultantsmay be invited by the Compensation Committee to makepresentations, to provide financial or otherbackground information or advice or to otherwise participate in Compensation Committee meetings.  The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives.  The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of Gran Tierra, as well as authority to obtain, at the expense of Gran Tierra, advice and assistance from internal and external legal, accounting or other advisors and consultants and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties.  In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation ofexecutiveand director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms.

During the past fiscal year,the Compensation Committee did not engage any compensation consultant.

Under its charter, the Compensation Committee may form, and delegate authority to, subcommittees, as appropriate.  In 2008, the Compensation Committee did not form any subcommittees.

The Compensation Committee makes adjustments to annual compensation, recommends bonus and equity awards in December of each year, and establishes new performance objectives at one or more meetings held during the first quarter of the year.  Generally, the Compensation Committee’s process comprises two related elements:the recommendation of compensation levels and the establishment of performance objectives for the current year.  In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to hiscompensationas well as awards to be granted.  For all executives and directors, as part of its deliberations, the Compensation Committee may review and consider, as appropriate,materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels, current company-wide compensation levels, and independent compensation surveys for the petroleum industry in Canada for peer groupings within the industry.

The specific determinations of the Compensation Committee with respect to executive compensation for fiscal 2008are described in greater detail in the section of this proxy statement entitled “Compensation Discussion and Analysis.”

15.

Compensation Committee Interlocks and Insider Participation

As noted above, Gran Tierra’s Compensation Committee consists of Messrs. Johnson, Scott, and Dawson.  None of the members of the Compensation Committee has at any time been an officer or employee of Gran Tierra, except that Mr. Scott served as CEO of Gran Tierra on an interim basis from January 2005 to April 2005.  No member of the Board or of the Compensation Committee served as an executive officer of another entity that had one or more of Gran Tierra’s executive officers serving as a member of that entity’s board or compensation committee.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee of the Board of Directors is responsible for identifying, reviewing and evaluating candidates to serve as directors of Gran Tierra (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, recommending to the Board for selection candidates for election to the Board of Directors, making recommendations to the Board regarding corporate governance issues, assessing the performance of the Board and management, and developing a set of corporate governance principles for Gran Tierra. The Nominating and Corporate Governance Committeeis composed of three directors: Messrs. Dawson, Scott, and Johnson.  All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 803(a)(2) of the NYSE Amex listing standards).  The Nominating and Corporate Governance Committee met twotimes during the fiscal year.  The Nominating and Corporate Governance Committee has adopted a written charter that is available to stockholders on Gran Tierra’s website at www.grantierra.com.

The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements and having the highest personal integrity and ethics.  The Nominating and Corporate Governance Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of Gran Tierra, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of Gran Tierra’s stockholders.  However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time.  Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of Gran Tierra and the long-term interests of stockholders.  In conducting this assessment, the Nominating and Corporate Governance Committee considers diversity, age, skills, and such other factors as it deems appropriate given the current needs of the Board and Gran Tierra, to maintain a balance of knowledge, experience and capability.  In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews these directors’ overall service to Gran Tierra during their terms, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair the directors’ independence.  In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for NASDAQ and NYSE Amexpurposes, which determination is based upon applicable NASDAQ and NYSE Amex listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary.  The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board.  The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.  In fiscal 2008, neither the Nominating and Corporate Governance Committee nor the Board paid any fees to any third partyto assist in the process of identifying or evaluating director candidates.

2 The material in this report is not “soliciting material,” is furnished to, but not deemed "filed" with, the Commission and is not deemed to be incorporated by reference in any filing of Gran Tierra under the Securities Act or the Exchange Act, other than Gran Tierra’s Annual Report on Form 10-K, where it shall be deemed to be “furnished,” whether made before or after the date hereof and irrespective of any general incorporation language in any such filing

16.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders.  The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder.  Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: Gran Tierra Energy Inc., 300, 611-10th Avenue S.W., Calgary, Alberta T2R 0B2, Canada, Attention: Director Nominations.  This written recommendation must be delivered at least 120 days prior to the anniversary of the mailing of Gran Tierra’s proxy statement for the last annual meeting of stockholders.  Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record holder of Gran Tierra’s stock.  Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

The Reserves Committee oversees Gran Tierra’s (1) annual review of its oil and gas reserves, (2) procedures for evaluating and reporting its oil and gas producing activities, and (3) compliance with applicable regulatory and securities laws relating to the preparation and disclosure of information with respect to its oil and gas reserves.  The Reserves Committee also consults with the Audit Committee on matters relating to Gran Tierra’s oil and gas reserves which impact Gran Tierra’s financial statements.  The Reserves Committeeis composed of three directors: Messrs. Johnson, Coffield, and Scott.  All members of the Reserves Committee are independent (as independence is currently defined in Rule 803(a)(2) of the NYSE Amex listing standards), other than Mr. Coffield, Gran Tierra’s Chief Executive Officer.  The Reserves Committee met two times during fiscal 2008.  The Reserves Committee has adopted a written charter that is available on Gran Tierra’s website at www.grantierra.com.

Proposal 2

Approval of Increase in Number of Authorized Shares of Common Stock

The Board of Directors is requesting stockholderapproval of an amendment to Gran Tierra’s amended Articles of Incorporation to increase Gran Tierra’s authorized number of shares of common stock from 300,000,000 shares to 570,000,000 shares.  If approved, the fourth article of Gran Tierra’s amended Articles of Incorporation will be amended to provide that the total number of authorized shares of Gran Tierra’s common stock shall be 570,000,000 shares, and therefore that the total authorized shares, including the current 25,000,000 shares of blank check preferred stock and shares of Special A Voting Stock and Special B Voting Stock shall be 595,000,002 shares.  If this Proposal 2 is approved, the first two paragraphs of the fourth article of Gran Tierra’s amended Articles of Incorporation shall be amended to read in their entirety as follows:

Fourth Article

The total number of shares of all classes of stock which the Corporation shall have authority to issue is five hundred ninety-five million and two (595,000,002), to be divided into four (4) classes, of which five hundred seventy million (570,000,000) shares, par value of $0.001, shall be designated as Common Stock (“Common Stock”); one (1) share, par value of $0.001, shall be designated as Special A Voting Stock (the “Special A Voting Stock”); one (1) share, par value of $0.001, shall be designated as Special B Voting Stock (the “Special B Voting Stock”); and twenty-five million (25,000,000) shares, par value of $0.001, shall be designated as Preferred Stock (“Preferred Stock”).

A.  Common Stock

The aggregate number of shares of Common Stock which the Corporation shall have authority to issue is five hundred seventy million (570,000,000) shares, par value of $0.001 per share. All stock when issued shall be fully paid and non-assessable. The Board of Directors of the Corporation may, at its discretion and by resolution of the Board of Directors, issue any authorized but unissued Common Stock of the Corporation which has not been reserved for issuance upon the exercise of any outstanding warrants, options, or other documents evidencing the right to acquire the Common Stock of the Corporation.

The additional common stock to be authorized by adoption of the amendment would have rights identical to the currently outstanding common stock of Gran Tierra.  Adoption of the proposed amendment and issuance of the common stock would not affect the rights of the holders of currently outstanding common stock of Gran Tierra, except for effects incidental to increasing the number of shares of Gran Tierra’s common stock outstanding, such as dilution of the earnings per share and voting rights of current holders of common stock.  If the amendment is adopted, it will become effective upon filing of a Certificate of Amendment to Articles of Incorporation with the Secretary of State of the State of Nevada.

Holders of the common stock are entitled to one vote for each share on all matters submitted to a stockholder vote. Holders of common stock do not have cumulative voting rights. Therefore, holders of a majority of the shares of common stock voting for the election of directors can elect all of the directors. Holders of the common stock representing a majority of the voting power of the capital stock issued, outstanding and entitled to vote, represented in person or by proxy, are necessary to constitute a quorum at any meeting of stockholders. A vote by the holders of a majority of the outstanding shares of common stock is required to effectuate certain fundamental corporate changes such as liquidation, merger or an amendment to the articles of incorporation.

Holders of common stock are entitled to share in all dividends that the Board of Directors, in its discretion, declares from legally available funds. In the event of a liquidation, dissolution or winding up, each outstanding share entitles its holder to participate pro rata in all assets that remain after payment of liabilities and after providing for each class of stock, if any, having preference over the common stock. Holders of the common stock have no pre-emptive rights, no conversion rights and there are no redemption provisions applicable to the common stock.

18.

In addition to the 238,710,473 shares of common stock outstanding on December 31, 2008, which number includes 10,984,126 shares of common stock issuable upon the exchange of the Goldstrike Exchangeable Shares issued to certain former shareholders of Gran Tierra Canada and 37,254,143 shares of common stock issuable upon the exchange of the Solana Exchangeable Shares issued to certain former shareholders of Solana, approximately 11,403,870 shares were issuable upon exercise of outstanding options, approximately 13,348,351 shares were issuable upon exercise of outstanding warrants, and approximately 6,443,966 shares were reserved for future grants under Gran Tierra’s 2007 Equity Incentive Plan.  The total number of shares reserved under Gran Tierra’s 2007 Equity Incentive Plan is 18,000,000 shares.

The approval of the amendment will not alter Gran Tierra’s present ability to issue up to 25,000,000 shares of its blank check preferred stock.

Although, at present, the Board of Directors has no plans to issue the additional shares of common stock, it desires to have the shares available to provide additional flexibility to use its capital stock for business and financial purposes in the future.  Gran Tierra believes it is important to retain a significant reserve of authorized but unissued common stock that could be used to raise additional capital through the sale of securities, declare stock dividends or stock splits, acquire another company or its business or assets, create negotiating leverage and flexibility in the event of an unfriendly takeover bid or establish a strategic relationship with a corporate partner, among other uses.

If approved, the proposed amendment would authorize additional shares of common stock that will be available in the event that the Board of Directors determines to undertake any of the above actions.  In addition, if a person or group of persons attempts a hostile takeover of Gran Tierra, such shares could be issued in connection with a stockholder rights plan, or poison pill or rights plan which would allow stockholders (other than the hostile parties) to purchase Gran Tierra’s common stock at a discount to the then current market price, which would have a dilutive effect on the hostile parties.  Although this proposal to increase the authorized common stock has been prompted by business and financial considerations and not by the threat of any hostile takeover attempt (nor is the Board currently aware of any such attempts directed at Gran Tierra), nevertheless, stockholders should be aware that approval of the proposal could facilitate future efforts by Gran Tierra to deter or prevent changes in control of Gran Tierra, including transactions in which the stockholders might otherwise receive a premium for their shares over the then current market prices.  Any additional equity financings may be dilutive to stockholders, and a debt financing, if available, may involve restrictions on stock dividends and other restrictions on Gran Tierra.  Moreover, while Gran Tierra continually evaluates potential acquisitions and other strategic transactions, it has no present agreements or commitments with respect to issuing shares of common stock as part of any acquisition.

If the amendment is adopted, 270,000,000 additional shares of Gran Tierra’s common stock will be available for issuance at the discretion of Gran Tierra’s Board, except that certain large issuances, such as future new issuances or series of related issuances that would result in an increase of the current shares outstanding by 20% or more, may require stockholder approval in accordance with the requirements of the NYSE Amex listing standards, and certain stock-based employee benefit plans may require stockholder approval in order to obtain desirable treatment under tax or securities laws and accounting regulations.

Gran Tierra’s Board believes it desirable that Gran Tierra have the flexibility to issue the additional shares as described above.  As is typical in publicly held energy companies, the holders of common stock have no pre-emptive rights to purchase any stock of Gran Tierra.  Stockholders should be aware that the issuance of additional shares could have a dilutive effect on earnings per share and on the equity ownership of the present holders of common stock.  No actions are currently being taken with respect to any large issuance of additional shares.

Each share of Gran Tierra’s common stock, Goldstrike Exchangeable Share, and Solana Exchangeable Share has one vote.  In order for Proposal 2 to be approved by Gran Tierra’s stockholders, it must receive “For” votes from the holders of shares of Gran Tierra’s common stock, Goldstrike Exchangeable Shares, and Solana Exchangeable Shares collectively entitling them to exercise at least a majority of the combined voting power of the total number of outstanding shares of Gran Tierra’s common stock, Goldstrike Exchangeable Shares, and Solana Exchangeable Shares.  As a result, abstentions and broker non-votes will have the same effect as negative votes.

References to voting power of Goldstrike Exchangeable Shares refer to the voting power exercised through the Goldstrike Trustee with respect to the Goldstrike Exchangeable Shares, whether by the Goldstrike Trustee or by proxy, and references to voting power of Solana Exchangeable Shares refer to the voting power exercised through the Solana Trustee with respect to the Solana Exchangeable Shares, whether by the Solana Trustee or by proxy.

Proposal 3

Ratification of Selection of Independent Auditors

The Audit Committee of the Board of Directors has selected Deloitte & Touche LLP as Gran Tierra’s independent auditors for the fiscal year ending December 31, 2009 and has further directed that management submit the selection of independent auditors for ratification by the stockholders at the annual meeting.  Deloitte & Touche LLP has audited Gran Tierra’s financial statements since its inception in 2005.  Representatives ofDeloitte & Touche LLP are expected to be present at the annual meeting.  They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither Gran Tierra’s Bylaws nor other governing documents or law require stockholderratification of the selection of Deloitte & Touche LLP as Gran Tierra’s independent auditors.  However, the Audit Committee of the Board is submitting the selection of Deloitte & Touche LLP to the stockholders for ratification as a matter of good corporate practice.  If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm.  Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of Gran Tierra and its stockholders.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and voting at the annual meeting will be required to ratify the selection of Deloitte & Touche LLP.  Abstentions and broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

Before Gran Tierra engages an independent public accountant to render audit services, any engagement covering audit or non-audit services by the auditors is approved by Gran Tierra’s Audit Committee or the engagement to render services is entered into pursuant to pre-approval policies and procedures established by the Audit Committee.  The pre-approval policy adopted by Gran Tierra’s Audit Committee on March 9, 2006 to permit pre-approval of non-audit services is attached as Schedule A to the charter of the Audit Committee, which was filed as Exhibit 99.1 to Gran Tierra’s Annual Report on Form 10-KSB for 2005.  This policy requires that the Audit Committee consider, prior to pre-approving any non-audit services, multiple factors taken as a whole, including whether the services are prohibited pursuant to SEC rules, whether the auditors are best positioned to provide the services, and the percentage of total services the non-audit services will comprise.  Requests for non-audit services will be made in writing to Gran Tierra’s independent auditor specifying the services requested and the reasons for the request, and the chairperson of the Audit Committee will be copied on the communication.  Gran Tierra’s independent auditor must respond to Gran Tierra’s request with a description of the services, the fees that it will charge, and a request for pre-approval of the services plus pre-approval of 10% over the amount.  The chairperson of the Audit Committee will then make a determination based on all of the relevant factors, and if approved report back to the Audit Committee at the next Audit Committee meeting for ratification.

The Audit Committee has determined that the rendering of the services other than audit services by Deloitte & Touche LLP is compatible with maintaining the principal accountant’s independence.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires Gran Tierra’s directors and executive officers, and persons who own more than ten percent of a registered class of Gran Tierra’s equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and other equity securities of Gran Tierra.  Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish Gran Tierra with copies of all Section 16(a) forms they file.

To Gran Tierra’s knowledge, based solely on a review of the copies of such reports furnished to Gran Tierra and written representations that no other reports were required, during the fiscal year ended December 31, 2008, all Section 16(a) filing requirements applicable to its officers, directors and greater than ten percent beneficial owners were complied with.

Executive Summary

Gran Tierra has designed its executive compensation program to motivate and reward our executives for company performance and to attract and retain talented executives.  Gran Tierra’s compensation program consists of three basic elements—base salary, short term cash bonus and long term equity incentives.  At least 74% of our total compensation for the executive officers listed in the Summary Compensation table below, or named executive officers, is linked to Gran Tierra’s performance and individual performance in the form of performance-based cash and equity awards.  We believe this provides our executives an opportunity to earn above average compensation if Gran Tierra delivers superior results.

We link a portion of our executives’ cash compensation to Gran Tierra’s performance measured by achievement of budget targets for items such as production, reserves, capital expenditures, revenues and operating costs, as well as other factors such as liquidity, share price performance given overall market conditions, and other objectives specific to Gran Tierra’s situation at the time.  In addition, we provide long-term incentives to our executives and employees in the form of stock options.  Options generally vest over three years, linking executives’ rewards directly to their ability to create value for our shareholders and providing an incentive for our executives to remain with Gran Tierra over the long term.

The global economic downturn has presented challenges for many companies, including Gran Tierra.  The price of oil directly impacts the performance of Gran Tierra.  In 2008, we have seen fluctuations in the price of West Texas Intermediate Crude oil (the reference price for most of our contracts) of $32.41 to $147.27.  However, due to the past financing activities of Gran Tierra and Solana as well as high operating cash flow during periods of high oil prices, Gran Tierra is in a very strong position from a liquidity standpoint.  We have no debt and have the financial resources with current cash balances and our projected cash flows for 2009 to complete our budgeted capital program and remain debt free.  Our strong cash position allowed the Compensation Committee to reward executives for having met or exceeded all individual objectives in addition to our acquisition of Solana Resources Ltd, all of which contributed to our stability for 2009 in the face of the global economic downturn.  Equity incentives were a strong part of the 2008 compensation package, which reflects the Compensation Committee’s commitment to tying executive compensation directly to company performance and shareholder return.

24.

Compensation Objectives

The overall objectives of Gran Tierra’s compensation program are to attract and retain key executives who are the best suited to make Gran Tierra successful and to reward individual performance to motivate Gran Tierra’s executives to accomplish Gran Tierra’s goals.

Compensation Process     

The Compensation Committee of the Gran Tierra Board, or the “Compensation Committee”, recommends amounts of compensation for Gran Tierra’s Chief Executive Officer, or the “Chief Executive Officer”, for approval by the Gran Tierra Board. The Chief Executive Officer recommends amounts of compensation for Gran Tierra’s other executive officers to the Compensation Committee, which considers these recommendations in connection with the goals and criteria discussed below. The Compensation Committee then makes its determination, taking the Chief Executive Officer’s recommendations into account, and makes its recommendations to the Gran Tierra Board for approval.  The Compensation Committee also recommends compensation for directors in the form of fees and long term equity incentives.  Neither Gran Tierra nor the Compensation Committee utilizes a compensation consultant.

Gran Tierra’s practice is to consider compensation annually (at year-end), including the award of equity based compensation.

Elements of Compensation

The Compensation Committee, which consists of three non-executive directors, has determined that Gran Tierra shall have three basic elements of compensation — base salary, cash bonus and equity incentives. Each component has a different purpose.

Gran Tierra believes that base salaries at this stage in Gran Tierra’s growth must be competitive to attract and retain executives. Gran Tierra believes that principal performance incentives should be in the form of long-term equity incentives given the long term nature of Gran Tierra’s business plan. Long-term incentives to date have been in the form of stock options but Gran Tierra’s equity plan also provides for other incentive forms, such as restricted stock and stock bonuses, which the Compensation Committee is not considering at this time. Short-term cash bonuses are a common element of compensation in Gran Tierra’s industry and among Gran Tierra’s peers to which Gran Tierra must pay attention.  For any given period Gran Tierra’s ability and desire to use cash bonuses are closely tied to its immediate cash resources. The Compensation Committee ultimately considers the split between the three forms of compensation relative to Gran Tierra’s peers for each position, relative to the contributions of each executive, the operational and financial achievements of Gran Tierra and Gran Tierra’s financial resources. This exercise has been based on consensus among the members of the Compensation Committee, all of whom have significant experience in the oil and gas exploration and production business.

Third Party Source Used

For 2008 salaries, Gran Tierra subscribed to the “2007 Mercer Total Compensation Survey for the Petroleum Industry” which covers oil and gas companies located in Canada, and which presents compensation components and statistical ranges by position description for peer groupings within the industry. The survey is published annually and is widely recognized as a leading survey of its kind in Canada to provide information for salaries and bonuses.  For 2008 bonuses and long term incentives, determined in December of 2008, the “2008 Mercer Total Compensation Survey for the Petroleum Industry” was used.

The survey provider is Mercer Human Resource Consulting. The primary purpose of the survey is to collect and consolidate meaningful data on salaries and benefits in the oil and gas industry in Canada, including those with international operations. The original 2007 survey participants were 158 companies in the oil and gas industry based in Canada, including those with international operations. The survey divided the 158 companies into six peer groups based on relative levels of production and revenues. There are 48 companies in Gran Tierra’s peer group with average production between 1,000 and 4,000 barrels of oil equivalent per day, including those with international operations. The results of the survey and the participants are confidential and cannot be disclosed in accordance with the confidentiality agreement signed with the survey provider.  For executives based in Bogota and Buenos Aires, local market surveys were used as a similar data source for 2008 salaries and bonuses.

25.

In 2008, the companies in the Mercer Survey were organized differently, and Gran Tierra had grown as a company, and no longer fit the peer group used in December 2007 when salaries were determined.  The Compensation Committee used a group of 33 companies from the Mercer Survey that was approved by both management and the Compensation Committee.  Those 33 companies are: ARC Resources Ltd., Anderson Energy Ltd., Baytex Energy Trust, Bonavista Energy Trust, Breaker Energy Ltd., Compton Petroleum Corporation, Connacher Oil and Gas Limited, Crescent Point Energy Trust, Crew Energy, Daylight Resources Trust, Enerplus Resources Fund, Fairborne Energy Ltd., First Calgary Petroleums Ltd., Harvest Energy Trust, Highpine Oil & Gas Limited, Iteration Energy Ltd., NuVista Energy Ltd., Paramount Energy Trust, Paramount Resources, Pengrowth Corporation, Penn West Energy Trust, PetroKazakhstan Inc., Petrobank Energy and Resources Ltd., Progress Energy Trust, ProspEx Resources Ltd., Rock Energy Inc., Sherritt International, TriStar Oil & Gas Ltd., Trilogy Energy Trust, True Energy Trust, Vermilion Energy Trust, WesternZagros Resources Ltd., and Zargon Energy Trust.

While our Compensation Committee believes that compensation survey data are useful guides for comparative purposes, we believe that a successful compensation program also requires that the Compensation Committee apply its own judgment and subjective determination of individual performance by our executives.  Therefore, the Compensation Committee applies its judgment in reconciling the program’s objectives with the realities of rewarding excellent performance and retaining valued employees and, in the Compensation Committee’s view, provides adequate safeguards to the compensation program such that it does not encourage these individuals to take unnecessary or excessive risks which could threaten the existence of Gran Tierra.

Salary

Base salaries were determined by the Compensation Committee based upon its review of the Mercer survey, targeting the 50th—75th percentile as being appropriate to retain the services of Gran Tierra’s executives, the exact amount determined by the Compensation Committee’s subjective assessment of the appropriate salary for each executive given their performance and roles within Gran Tierra.

The Compensation Committee recommended to the Gran Tierra Board, and the Gran Tierra Board approved the following annual salaries for 2008 as follows:

Mr. Coffield	$	216,399
Mr. Wei	$	179,178
Mr. Orunesu	$	207,000
Mr. Dyes	$	220,000
Mr. Eden	$	192,922

Bonus     

For 2008, the Compensation Committee used the 2007 Mercer survey to establish the level of bonuses for Gran Tierra’s executives. The Compensation Committee again targeted the 50th — 75th percentile for the position within the peer group for the industry as being appropriate to retain the services of Gran Tierra’s executives. The Compensation Committee determined bonuses for Gran Tierra’s executives based on assessment of performance against individual objectives for 2008, in addition to consideration of Gran Tierra’s operational and financial results, and financial resources. 

The weighting of all of the individual performance objectives and the percentage contribution of the individual performance objectives was assessed by the Compensation Committee in determining bonuses.

Individual objectives defined for 2008 were as follows:

Chief Executive Officer - The principal objectives for Gran Tierra’s Chief Executive Officer and President, which have been recommended by the Compensation Committee and approved by the Gran Tierra Board, are as follows:

2009 performance objectives have been developed for the named executive officers and in terms of approach, are not materially different from the 2008 performance objectives.

Equity Incentives     

In December 2008, the Compensation Committee considered elements of individual, business unit and corporate performance in determining grant levels and granted options under the terms of Gran Tierra’s 2007 Equity Incentive Plan to each of Gran Tierra’s executive officers as follows: Mr. Coffield 600,000 shares; Mr. Eden 400,000 shares; Mr. Orunesu 100,000 shares; and Mr. Dyes 300,000 shares.

Termination and Change in Control Provisions

Gran Tierra’s employment agreements with Gran Tierra’s executive officers contain termination and change in control provisions. These provisions provide that Gran Tierra’s executive officers will receive severance payments in the event that their employment is terminated other than for “cause” or if they terminate their employment with us for “good reason”, as discussed in “Agreements with Executive Officers” below. The termination and change-in control provisions are industry standard clauses reached with the executives in arms-length negotiations at the time that they entered into the employment agreements with us.

The employment agreements entered into with Messrs. Coffield, Eden, Wei, Dyes and Orunesu have virtually identical terms except for:

· the position held by each such person;

· the number of weeks of vacation allowed (5 weeks of paid vacation for each executive except Mr. Dyes who is permitted 4 weeks of paid vacation);

· limitations on business class travel (Messrs. Wei, Dyes and Orunesu may only travel business class for international flights and coach class for domestic travel whereas Messrs. Coffield and Eden may travel business class for most flights);

· travel to the United States by Mr. Dyes from Colombia, at the expense of Gran Tierra Energy Colombia Ltd., for personal business, as often as reasonably necessary, subject to residency requirements of Colombia; and

· reasonable housing, auto, club and living expenses in Colombia provided for Mr. Dyes by Gran Tierra Energy Colombia Ltd. consistent with the benefits provided to Mr. Dyes in the first quarter of 2006

The employment agreements provide that the respective executive will:

· receive a base salary, as determined by the Gran Tierra Board;

· be eligible to receive an annual bonus, as determined by the Board; and

· be eligible to participate in the stock option plans of Gran Tierra.

30.

The bonuses are to be paid within 60 days of the end of the preceding year based on the executive performance.

The employment agreements do not have terms of specified duration. The employment agreements provide for severance payments to each executive, in the event the executive is terminated without cause or the executive terminates the agreement for good reason, in the amount of two times total compensation for the prior year (in the case of Messrs. Coffield and Wei) or in the amount of one times total compensation for the prior year (in the case of Messrs. Eden, Dyes and Orunesu).

“Good reason” includes (i) an adverse change in the executive’s position, title, duties or responsibilities, or any failure to re-elect him to such position (except for termination for “cause”), (ii) a reduction in the executive’s base salary unless all other executive officers are similarly reduced, or a change in the basis upon which the executive’s annual compensation is paid or determined except that annual performance bonuses are discretionary and shall not be considered adverse under the agreement if a performance bonus is reduced from a prior year or not paid, (iii) a change in control, or (iv) any breach by the employer of any material provision of the employment agreement.

A “Change in Control” is defined as (i) a dissolution, liquidation or sale of all or substantially all of the assets of Gran Tierra; (ii) a merger or consolidation in which Gran Tierra is not the surviving corporation; (iii) a reverse merger in which Gran Tierra is the surviving corporation but the shares of Gran Tierra’s common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (iv) the acquisition by any person, entity or group within the meaning of Section 13(d) or 14(d) of the Securities Exchange Act (excluding any employee benefit plan, or related trust, sponsored or maintained by Gran Tierra or any affiliate of Gran Tierra) of the beneficial ownership (within the meaning of Rule 13d-3 of the Exchange Act) of securities of Gran Tierra representing at least fifty percent (50%) of the combined voting power entitled to vote in the election of directors.

All agreements include standard insurance, non-competition and confidentiality provisions.

STOCKHOLDER APPROVAL OF STOCK PLANS

Equity Compensation Plan Information

Plan category	Number of securities to be issued upon exercise of options		Weighted average exercise price of outstanding options		Number of securities remaining available for future issuance
Equity compensation plans approved by security holders		11,406,870	$	2.13		6,443,966
Equity compensation plans not approved by security holders		—		—		—
Total		11,406,870		2.13		6,443,966

The only equity compensation plan approved by our stockholders is our 2007 Equity Incentive Plan, which is an amendment and restatement of our 2005 Equity Plan, under which the Board is authorized to issue options or other rights to acquire up to 18,000,000 shares of our common stock.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other annual meeting materialswith respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other annual meeting materialsaddressed to those stockholders.This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholdersand cost savings for companies.

This year, a number of brokers with account holders who are stockholders of Gran Tierrawill be “householding” Gran Tierra’s proxy materials.  A single Notice of Internet Availability of Proxy Materials or a single set of annual meeting materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders.  Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent.  If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice of Internet Availability of Proxy Materials or a separate set of annual meeting materials, please notify your broker.  Direct your written request to Gran Tierra Energy Inc., Martin Eden, Secretary, 300, 611-10th Avenue, S.W., Calgary, Alberta, T2R 0B2, Canada or contact Martin Eden at (403) 265-3221.  Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials or multiple sets of annual meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

Other Matters

The Board of Directors knows of no other matters that will be presented for consideration at the annual meeting.  If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.
