PROPOSAL 2
 
RATIFICATION OF AMENDMENTS TO OUR BYLAWS
TO
COMPLY WITH CERTAIN LISTING REQUIREMENTS OF THE TORONTO STOCK EXCHANGE

The Board is recommending the ratification of amendments to our Bylaws which comply with the listing requirements of the Toronto Stock Exchange, or TSX. The TSX has required that we submit these amendments to our stockholders for ratification.

The TSX required that we amend our Bylaws in order to meet TSX’s listing requirements. These amendments were as follows:

·Article III, Section 2(a) of the Bylaws was amended to clarify that all directors are in the same class and have equal voting rights; 

·A new Section (1) was added to Article V (and the other sections were appropriately renumbered), which new section specifies that Gran Tierra’s stock shall be issued in accordance with the Fourth Section of the Gran Tierra Articles of Incorporation at fair market value as determined by the Board, and that the consideration for the issuance of stock shall not be in the form of promissory notes or services to be performed, or any combination thereof;
·Article II, Section 5 was amended to provide that no proxy shall be voted after six (6) months from the date of its creation, unless such proxy provides for a longer period, which may not exceed 7 years from the date of its creation;

·Article II, Section 10 was added to provide that the Board shall have the power and authority at all meetings to sell, lease or exchange substantially all of the property and assets of Gran Tierra upon such terms as the Board deems expedient and in the best interests of the corporation and stockholders only upon the authorization of our stockholders holding the majority of the voting power; and

·Article II, Section 11 was added to provide that any stockholder of any class is entitled to dissent from, and obtain payment of the fair market value of his shares in the event of (1) an amendment to our Articles of Incorporation to add, change or remove any provision restricting or constraining the issue, transfer or ownership of shares of that class or restriction on the business that may be conducted by Gran Tierra, or the sale, lease or exchange of all or substantially all of our assets.

The Board requests that stockholders ratify the amendments, as the amendments were required by the TSX as a condition to the listing of our common stock on the TSX. If the amendments are not ratified, the Board in its discretion will determine what action, if any, to take, subject to approval from the TSX if required. If the amendments are ratified, the Board in its discretion may still determine at a later date to amend the Bylaws, subject to approval from the TSX if required, if it determines that such amendment would be in the best interests of Gran Tierra and its stockholders.

The Board believes that the foregoing amendments were in the best interests of Gran Tierra and its stockholders. To be approved, ratification of amendments to the Bylaws must receive more “For” votes than “Against” votes. For purposes of this vote abstentions and broker non-votes will not be counted for any purpose in determining whether this matter has been approved.

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 ourGran Tierra’s independent auditors for the fiscal year ending December 31, 20082009 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 ourGran Tierra’s financial statements since its inception in 2005.2005.  Representatives of Deloitte & 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 ourGran Tierra’s Bylaws nor other governing documents or lawslaw require stockholder ratification of the selection of Deloitte & Touche LLP as ourGran 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 & ToucheLLP.  BrokerAbstentions and broker non-votes and abstentions are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

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 9,000,000 shares of our common stock.

Amendments of 2007 Equity Incentive Plan

In June 2007, the Board adopted Gran Tierra’s 2007 Equity Incentive Plan, or the Plan, which was approved by our stockholders on October 10, 2007. The Plan is an amended, restated and retitled version of Gran Tierra’s 2005 Equity Incentive Plan. The Board subsequently amended the Plan on December 20, 2007 and January 14, 2008, respectively. The Board approved these amendments in order to meet certain listing requirements of the Toronto Stock Exchange, or the TSX. Specifically, the Board made the following amendments to the Plan, as required by the TSX:

·
Option grants below fair market value. The Plan generally provides that the exercise price for options granted under the Plan shall be not less than one hundred percent of the fair market value of our common stock subject to the option on the date of grant. The Plan permits options to be granted with an exercise price lower than the fair market value on the date of grant, provided such options are granted pursuant to an assumption or substitution for another option in the manner satisfying the provisions of Section 424(a) of the Internal Revenue Code of 1986, as amended, or the Code. The Plan was amended to provide that so long as our shares are listed for trading on the TSX, options granted below fair market value on the date of grant are subject to approval by the TSX, to the extent necessary to satisfy the TSX rules.

·
Amendment of the Plan or Stock Awards. The Plan previously provided that the Board could amend the Plan unless stockholder approval was required by Section 422 of the Code. The Plan was amended to include the following provisions:

·
No amendments to stock awards could be made if the common stock is listed on the TSX unless approved by the stockholders to the extent necessary to satisfy the TSX rules.

13



·
If an amendment reducing the stock option exercise price or extending the term of the stock option is made to a stock option held by an Insider, the amendment shall only be made effective after the approval is received of Disinterested Stockholders at a meeting of the stockholders of Gran Tierra. An “Insider” is defined to be an “insider” as defined under the policies of the TSX, as amended from time to time, which includes, among others, directors and senior officers of Gran Tierra or any subsidiary of Gran Tierra and includes an issuer, all of the voting securities of which are owned by such an officer. “Disinterested Stockholders” is defined as stockholders of Gran Tierra except Insiders who are eligible to receive stock awards, and such Insiders’ associates.

·
Amendments without Stockholder Approval. The Plan was amended to include a provision specifying the circumstances under which the Board could amend the Plan without stockholder approval, which provision specifies that: “the Board shall have the authority: (a) to make amendments to the Plan or a Stock Award of a housekeeping or administrative nature; (b) if the common stock is listed on the Toronto Stock Exchange subject to any required approval of the Toronto Stock Exchange, to change the vesting or termination provisions of a Stock Award or the Plan; (c) any amendment to reduce the option exercise price of an Option held by a non-insider; (d) amendments necessary to comply with provisions of applicable law or stock exchange requirements or for grants to qualify for favorable treatment under applicable laws; (e) the addition of any form of financial assistance by Gran Tierra for the acquisition by all or certain categories of Participants of common stock under the Plan, and the subsequent amendment of any such provisions; and (f) any other amendment, fundamental or otherwise, not requiring stockholder approval under the Code; provided, however, that no amendment shall be made without stockholder approval to the extent stockholder approval is necessary to satisfy the requirements of Section 422 of the Code.”
·
Limitations with respect to Insiders and Consultants. The Plan was amended to include limitations on grants to Insiders and consultants as follows:
·The maximum number of shares of common stock which may be reserved for issuance to Insiders, at any time, under the Plan and any other share compensation arrangement of Gran Tierra shall be 10% of the common stock issued and outstanding.

·The maximum number of shares of common stock which may be issued to Insiders under the Plan, at any time, and any other share compensation arrangement within any 12-month period shall be 10% of the common stock outstanding.

·The maximum number of shares of common stock which may be issued to any one Insider and such Insider’s associates under the Plan, at any time, within a 12-month period shall be 5% of the common stock outstanding.

·The number of stock options granted to any one consultant in any 12-month period under the Plan shall not exceed 2% of the issued and outstanding shares of common stock at the time of grant.
The essential features of the Plan are outlined below:
General

The Plan provides for the grant of stock options, restricted stock awards, stock appreciation rights, restricted stock units and other stock awards (collectively “awards”). Stock options granted under the Plan are not intended to qualify as incentive stock options within the meaning of Section 422 of the Code. Stock appreciation rights granted under the Plan may be tandem rights, concurrent rights or independent rights. See “U.S. Federal Income Tax Information” for a discussion of the tax treatment of awards. To date, Gran Tierra has granted only stock options under the Plan.
Purpose

The Board adopted the Plan, which is an amendment and restatement of the 2005 Equity Plan, or the Prior Plan, to provide a means by which employees, directors and consultants of Gran Tierra and its affiliates may be given an opportunity to purchase stock in Gran Tierra, to assist in retaining the services of such persons, to secure and retain the services of persons capable of filling such positions and to provide incentives for such persons to exert maximum efforts for the success of Gran Tierra and its affiliates. All of the approximately 128 employees, directors and consultants of Gran Tierra and its affiliates are eligible to participate in the Plan.
Administration

The Board administers the Plan. Subject to the provisions of the Plan, the Board has the power to construe and interpret the Plan and to determine the persons to whom and the dates on which awards will be granted, the number of shares of common stock to be subject to each award, the time or times during the term of each award within which all or a portion of such award may be exercised, the exercise price, the type of consideration and other terms of the award.

The Board has the power to delegate administration of the Plan to a committee composed of not fewer than two members of the Board. A committee may consist solely of two or more outside directors in accordance with Section 162(m) of the Code or solely of two or more non-employee directors in accordance with Rule 16b-3 of the Exchange Act. The Board has delegated administration of the Plan to the Compensation Committee of the Board. As used herein with respect to the Plan, the “Board” refers to any committee the Board appoints as well as to the Board itself.

1421.

 
Stock Subject to the Plan

An aggregateSecurity Ownership of 9,000,000 shares of common stock is reserved for issuance under the Plan. If awards granted under the Plan expire or otherwise terminate without being exercised, the shares of common stock not acquired pursuant to such awards again become available for issuance under the Plan. If Gran Tierra reacquires unvested stock issued under the Plan, the reacquired stock will not become available for reissuance under the Plan. As of April 1, 2008:

·
Stock options to purchase 74,167 shares had been exercised under the Plan, and an additional 5,651,664 shares were outstanding under the Plan, collectively representing 5.7% of Gran Tierra’s 99,988,644 shares of common stock issued and outstanding as of April 1, 2008 (the “Outstanding Capital Stock”), which number includes 11,827,776 shares of common stock issuable upon the exchange of outstanding Exchangeable Shares; and

·The entire 9,000,000 shares issued or issuable under the Plan represents 9.0% of Gran Tierra’s Outstanding Capital Stock.
Eligibility

Employees (including officers), directors, and consultants of both Gran Tierra and its affiliates are eligible to receive all types of awards under the Plan. No person may be granted awards under the Plan exercisable for more than 1,000,000 shares of common stock during any calendar year (“Section 162(m) Limitation”).
Terms of Options

The following is a description of the permissible terms of options under the Plan. Individual option grants may be more restrictive as to any or all of the permissible terms described below.
Exercise Price; Payment. The exercise price of options may not be less than 100% of the fair market value of the common stock on the date of grant, except as provided in the amendments as described above. The Plan defines the “fair market value” of the common stock on any given date as the closing price on that date for such stock (or the closing bid, if no sales were reported) as quoted on the exchange or market with the greatest volume of trading in the common stock. If options were granted to covered executives with exercise prices below fair market value, deductions for compensation attributable to the exercise of such options could be limited by Section 162(m) of the Code. See “U.S. Federal Income Tax Information.” The closing price of Gran Tierra’s common stock as reported on the American Stock Exchange on April 25, 2008 was $4.28 per share.

The exercise price of options granted under the Plan must be paid either in cash at the time the option is exercised or at the discretion of the Board, (1) by delivery of other common stock of Gran Tierra, (2) pursuant to a deferred payment arrangement or (3) in any other form of legal consideration acceptable to the Board. The Plan does not provide for financial assistance in exercising stock options.
Option Exercise. Options granted under the Plan may become exercisable in cumulative increments (“vest”) as determined by the Board. Shares covered by currently outstanding options under the Plan typically vest over a three year period in three annual installments during the participant’s employment by, or service as a director or consultant to, Gran Tierra or an affiliate (collectively, “service”). Shares covered by options granted in the future under the Plan may be subject to different vesting terms. The Board has the power to accelerate the time during which an option may vest or be exercised. In addition, options granted under the Plan may permit exercise prior to vesting, but in such event the participant may be required to enter into an early exercise stock purchase agreement that allows Gran Tierra to repurchase unvested shares, generally at their exercise price, should the participant’s service terminate before vesting. To the extent provided by the terms of an option, a participant may satisfy any federal, state or local tax withholding obligation relating to the exercise of such option by a cash payment upon exercise, by authorizing Gran Tierra to withhold a portion of the stock otherwise issuable to the participant, by delivering already-owned common stock of Gran Tierra or by a combination of these means.

Limitations with respect to Insiders and Consultants. The Plan, as a result of the amendments, provides that: (1) the maximum number of shares of common stock which may be reserved for issuance to Insiders, at any time, under the Plan and any other share compensation arrangement of Gran Tierra shall be 10% of the common stock issued and outstanding; (2) the maximum number of shares of common stock which may be issued to Insiders under the Plan, at any time, and any other share compensation arrangement within any 12-month period shall be 10% of the common stock outstanding; (3) the maximum number of shares of common stock which may be issued to any one Insider and such Insider’s associates under the Plan, at any time, within a 12-month period shall be 5% of the common stock outstanding; and (4) the number of stock options granted to any one consultant in any 12-month period under the Plan shall not exceed 2% of the issued and outstanding shares of common stock at the time of grant.
15

Term.

The maximum term of options under the Plan is 10 years. Options under the Plan generally terminate three months after termination of the participant’s service unless (1) such termination is due to the participant’s permanent and total disability (as defined in the Code), in which case the option may, but need not, provide that it may be exercised (to the extent the option was exercisable at the time of the termination of service) at any time within 12 months of such termination; (2) the participant dies before the participant’s service has terminated, or within three months after termination of such service, in which case the option may, but need not, provide that it may be exercised (to the extent the option was exercisable at the time of the participant’s death) within 18 months of the participant’s death by the person or persons to whom the rights to such option pass by will or by the laws of descent and distribution; or (3) the option by its terms specifically provides otherwise. A participant may designate a beneficiary who may exercise the option following the participant’s death. Individual option grants by their terms may provide for exercise within a longer period of time following termination of service.
The option term generally may be extended in the event that exercise of the option within these periods is prohibited. A participant’s option agreement may provide that if the exercise of the option following the termination of the participant’s service would be prohibited because the issuance of stock would violate the registration requirements under the Securities Act of 1933, as amended (the “Securities Act”), then the option will terminate on the earlier of (1) the expiration of the term of the option or (2) three months after the termination of the participant’s service during which the exercise of the option would not be in violation of such registration requirements.
Terms of Restricted Stock Awards and Purchases of Restricted Stock

Payment.
The Board determines the purchase price under a restricted stock purchase agreement but the purchase price may not be less than 100% of the fair market value of Gran Tierra’s common stock on the date of purchase. The Board may award stock bonuses in consideration of past services without a purchase payment.
The purchase price of stock acquired pursuant to a restricted stock purchase agreement under the Plan must be paid either in cash at the time of purchase or at the discretion of the Board, (1) by delivery of other common stock of Gran Tierra, (2) pursuant to a deferred payment arrangement or (3) in any other form of legal consideration acceptable to the Board.
Vesting.
Shares of stock sold or awarded under the Plan may, but need not be, subject to a repurchase option in favor of Gran Tierra in accordance with a vesting schedule as determined by the Board. The Board has the power to accelerate the vesting of stock acquired pursuant to a restricted stock purchase agreement under the Plan.
Restrictions on Transfer.
Rights under a stock bonus or restricted stock bonus agreement may be transferred only upon the terms and conditions of the award agreement as the Board shall determine in its discretion, except where such assignment is required by law or expressly authorized by the terms of the applicable stock bonus or restricted stock purchase agreement.
Stock Appreciation Rights

The Plan authorizes the grant of stock appreciation rights. Stock appreciation rights entitle the participant to receive upon exercise an appreciation distribution equal to the fair market value of that number of share equivalents in which the participant is vested under the independent stock appreciation rights less the fair market value of such number of shares of stock on the date of grant of the independent stock appreciation rights. The Plan defines the “fair market value” of the common stock on any given date as the closing price on that date for such stock (or the closing bid, if no sales were reported) as quoted on the exchange or market with the greatest volume of trading in the common stock. Appreciation distributions payable upon exercise of stock appreciation rights may, at the Board’s discretion, be made in cash, in shares of stock or a combination thereof.
Restrictions on Transfer

The Board may grant stock options that are transferable to the extent provided in the stock option agreement. Options generally are not transferable, except by will or by the laws of descent and distribution. Shares subject to repurchase by Gran Tierra under an early exercise stock purchase agreement may be subject to restrictions on transfer that the Board deems appropriate.
Adjustment Provisions

Transactions not involving receipt of consideration by Gran Tierra, such as a merger, consolidation, reorganization, stock dividend, or stock split, may change the type(s), class(es) and number of shares of common stock subject to the Plan and outstanding awards. In that event, the Plan will be appropriately adjusted as to the type(s), class(es) and the maximum number of shares of common stock subject to the Plan, and outstanding awards will be adjusted as to the type(s), class(es), number of shares and price per share of common stock subject to such awards.
16

Effect of Certain Corporate Transactions

In the event of (1) the sale, lease, license or other disposition of all or substantially all of the assets of Gran Tierra, (2) the sale or other disposition of all or substantially all of the outstanding securities of Gran Tierra, or (3) certain specified types of merger, consolidation or similar transactions (collectively, “corporate transaction”), any surviving or acquiring corporation may continue or assume awards outstanding under the Plan or may substitute similar awards. If any surviving or acquiring corporation does not assume such awards or substitute similar awards, then with respect to awards held by participants whose service with Gran Tierra or an affiliate has not terminated as of the effective date of the corporate transaction, the vesting of such awards (and, if applicable, the time during which such awards may be exercised) will be accelerated in full and the awards will terminate if not exercised (if applicable) at or prior to such effective date.
The Plan provides, that in the event of certain change of control events, any outstanding stock awards may be subject to additional acceleration of vesting and exercisability upon or after such change of control event, if such acceleration is provided for in the individual award holder’s stock award agreement
The acceleration of an award in the event of a corporate transaction or a change in control event may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain control of Gran Tierra.
Duration, Amendment and Termination

The Board may suspend or terminate the Plan without stockholder approval or ratification at any time or from time to time.
The Board may also amend the Plan at any time or from time to time. However, no amendment will be effective unless approved by the stockholders of Gran Tierra within 12 months before or after its adoption by the Board to the extent such approval is necessary to satisfy the requirements of Section 422 of the Code, no amendments to stock awards could be made if the common stock is listed on the TSX unless approved by the stockholders to the extent necessary to satisfy the rules of the TSX, and no amendment may reduce the exercise price or extend the term of an option granted to an Insider, unless approved by a majority of disinterested stockholders. The Board may, in its discretion, submit any other amendment to the Plan for stockholder approval.
U.S. Federal Income Tax Information

Stock Options, Restricted Stock Purchase Awards and Stock Bonuses.
Stock options, restricted stock purchase awards and stock bonuses granted under the Plan generally have the following federal income tax consequences. There are no tax consequences to the participant or Gran Tierra by reason of the grant. Upon acquisition of the stock, the participant normally will recognize taxable ordinary income equal to the excess, if any, of the stock’s fair market value on the acquisition date over the purchase price. However, to the extent the stock is subject to certain types of vesting restrictions, the taxable event will be delayed until the vesting restrictions lapse unless the participant elects to be taxed on receipt of the stock. With respect to employees, Gran Tierra is generally required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, Gran Tierra will generally be entitled to a business expense deduction equal to the taxable ordinary income realized by the participant.
Upon disposition of the stock, the participant will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock plus any amount recognized as ordinary income upon acquisition (or vesting) of the stock. Such gain or loss will be long-term or short-term depending on whether the stock was held for more than one year. Slightly different rules may apply to participants who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act.
Stock Appreciation Rights.
No taxable income is realized upon the receipt of a stock appreciation right, but upon exercise of the stock appreciation right the fair market value of the shares (or cash in lieu of shares) received must be treated as compensation taxable as ordinary income to the participant in the year of such exercise. Generally, with respect to employees, Gran Tierra is required to withhold from the payment made on exercise of the stock appreciation right or from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness, Section 162(m) of the Code and the satisfaction of a reporting obligation, Gran Tierra will be entitled to a business expense deduction equal to the taxable ordinary income recognized by the participant.

Potential Limitation on Company Deductions.
Section 162(m) of the Code denies a deduction to any publicly held corporation for compensation paid to certain “covered employees” in a taxable year to the extent that compensation to such covered employee exceeds $1 million. It is possible that compensation attributable to awards, when combined with all other types of compensation received by a covered employee from Gran Tierra, may cause this limitation to be exceeded in any particular year.
Certain kinds of compensation, including qualified “performance-based compensation,” are disregarded for purposes of the deduction limitation. In accordance with Treasury Regulations issued under Section 162(m), compensation attributable to stock optionsBeneficial Owners and stock appreciation rights will qualify as performance-based compensation if the award is granted by a compensation committee comprised solely of “outside directors” and either (1) the plan contains a per-employee limitation on the number of shares for which such awards may be granted during a specified period, the per-employee limitation is approved by the stockholders, and the exercise price of the award is no less than the fair market value of the stock on the date of grant, or (2) the award is granted (or exercisable) only upon the achievement (as certified in writing by the compensation committee) of an objective performance goal established in writing by the compensation committee while the outcome is substantially uncertain, and the award is approved by stockholders.
Awards to purchase restricted stock and stock bonus awards will qualify as performance-based compensation under the Treasury Regulations only if (1) the award is granted by a compensation committee comprised solely of “outside directors,” (2) the award is granted (or exercisable) only upon the achievement of an objective performance goal established in writing by the compensation committee while the outcome is substantially uncertain, (3) the compensation committee certifies in writing prior to the granting (or exercisability) of the award that the performance goal has been satisfied and (4) prior to the granting (or exercisability) of the award, stockholders have approved the material terms of the award (including the class of employees eligible for such award, the business criteria on which the performance goal is based, and the maximum amount — or formula used to calculate the amount — payable upon attainment of the performance goal).

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.

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

Compensation Process
 
Compensation Process     
The Compensation Committee of the Gran Tierra Board, or the “Compensation Committee”, recommends amounts of compensation for theGran Tierra’s Chief Executive Officer, or the “Chief Executive Officer”, for approval by our board of directors. Ourthe Gran Tierra Board. The Chief Executive Officer recommends amounts of compensation for ourGran Tierra’s other executive officers to ourthe Compensation Committee, which considers these recommendations in connection with the goals and criteria discussed below. The Compensation Committee then makes its determination, taking ourthe Chief Executive Officer’s recommendations into account, and makes its recommendations to our boardthe Gran Tierra Board for approval.  The Compensation Committee also recommends compensation for directors in the form of directors for approval.fees and long term equity incentives.  Neither Gran Tierra nor the Compensation Committee utilizes a compensation consultant.
 
OurGran Tierra’s practice is to consider compensation annually (at year-end), including the award of equity based compensation. Prior to 2007, our compensation practices were largely discretionary. During 2007, we have adopted an increasingly formalized framework whereby our Compensation Committee has defined items of corporate performance to be considered in future compensation, which include budget targets (production, reserves, capital expenditures, operating costs), and which it expects will include financial measures (e.g., liquidity) and share price performance, in addition to other objectives. Our Compensation Committee has defined elements of personal performance to be met by the achievement of agreed objectives. This process was initiated by the Chief Executive Officer, whose objectives have been documented and accepted by the board of directors. Objectives for the remaining executives are within the context of the Chief Executive Officer’s objectives and include other, more specific goals.
 
Elements of Compensation
 
OurThe Compensation Committee, which consists of three non-executive directors, has determined that weGran Tierra shall have three basic elements of compensation — base salary, cash bonus and equity incentives. Each component has a different purpose.

We believeGran Tierra believes that base salaries at this stage in ourGran Tierra’s growth must be competitive in order to attract and retain our executives. We believeGran Tierra believes that principal performance incentives should be in the form of long-term equity incentives given the financial resources of our company and the longer-termlong term nature of ourGran Tierra’s business plan. Long-term incentives to date have been in the form of stock options but ourGran 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 ourGran Tierra’s industry and among ourGran Tierra’s peers to which weGran Tierra must pay attention, but ourattention.  For any given period Gran Tierra’s ability and desire to use cash bonuses are closely tied to theits immediate cash resources of our company.resources. The Compensation Committee ultimately considers the split between the three forms of compensation relative to ourGran Tierra’s peers for each position, relative to the contributions of each executive, and the operational and financial achievements of our companyGran Tierra and ourGran Tierra’s financial resources. This exercise has been based on consensus among the members of the Compensation Committee.Committee, all of whom have significant experience in the oil and gas exploration and production business.

Executive compensation through 2005 and the first part of 2006 was sufficient to attract and retain our management team but had fallen significantly behind industry norms by the end of 2006 and as our company grew beyond a start-up phase. In late-2006, the Compensation Committee determined that it was necessary to review compensation andThird Party Source Used
For 2008 salaries, Gran Tierra subscribed to the compensation survey described below as a starting point for a more structured and competitive compensation process. Our goal is to provide competitive compensation and an appropriate compensation structure for an emerging oil and gas company relative to our stage of growth, financial resources and success.

Third Party Source Used
In late 2006, we subscribed to the “2006“2007 Mercer Total Compensation Survey for the Petroleum Industry,”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. In 2007,Canada to provide information for salaries and bonuses.  For 2008 bonuses and long term incentives, determined in December of 2008, the company subscribed to the “2007“2008 Mercer Total Compensation Survey for the Petroleum Industry” in order to provide information for 2008 salaries and 2007 bonuses.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 ourGran 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.

Salary  For executives based in Bogota and Buenos Aires, local market surveys were used as a similar data source for 2008 salaries and bonuses.
 
Salary amounts for our executive officers for 2006 were pre-determined based on individually-negotiated agreements with each of the executive officers when they joined our company. Prior to November 2005, we were a private Canadian company incorporated in January 2005. For 2005 and for 2006, the four inaugural executives of our company received the same base salary of approximately $150,000 per year. Rafael Orunesu, who is President of our operations in Argentina, was the first hire of our company in March 2005. Mr. Orunesu negotiated his employment agreement directly with our board of directors. Dana Coffield, James Hart and Max Wei, who are located in Calgary, joined Gran Tierra in May 2005 and collectively negotiated terms of their employment with our board of directors. As a start-up company with limited financial resources, base salary in all instances was a discount to prior base salaries for each executive at their previous employer. All executives agreed to the same base compensation to reflect the team nature of the venture. All signed employment agreements outlined the potential for base salary increases, equity incentives and cash bonuses if deemed appropriate by the board of directors. The agreements did not specify the amount or any criteria for determining the bonuses and equity incentives, and so these determinations may be made by our board of directors in its sole discretion. The executives purchased founding shares to substantiate their commitment to our company and provide additional financial incentives.

In April 2006, Mr. Dyes became our President, Argosy Energy/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 Colombia. He too negotiated his employment agreement, which provided for his annual base salary of $105,000 plus an annual supplemental salary of up to $42,000, the exact amount to be determined by the amount of time that he spends in Colombia in excess of what is required under the employment agreement. This agreement, too, did not specify the amount or any criteria for determining the bonusesLtd., Baytex Energy Trust, Bonavista Energy Trust, Breaker Energy Ltd., Compton Petroleum Corporation, Connacher Oil and equity incentives,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 so these determinations may be made by our board of directors in its sole discretion.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.
 
In January 2007, Mr. Eden becameWhile our Chief Financial Officer. The terms of Mr. Eden’s employment agreement were individually negotiated by Mr. Eden, andCompensation Committee believes that compensation survey data are described below in “Agreements with Executive Officers”. The agreement did not specify the amount or any criteriauseful guides for determining the bonuses and equity incentives, and so these determinations may be made by our board of directors in its sole discretion.
James Hart, our previous Chief Financial Officer, continued as an employee in the capacity of Chief Strategy Officer until February 28, 2007. After his resignation as an employee, he continued with the company ascomparative purposes, we believe that a director until October 10, 2007, at which time he resigned his directorship.

Base salaries for 2008 will be as follows:
Mr. Coffield — $261,847
Mr. Eden — $233,439
Mr. Wei — $216,809
Mr. Orunesu — $207,000
Mr. Dyes — $220,000

For 2007,successful compensation program also requires that the Compensation Committee recommendedapply 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 boardcompensation program such that it does not encourage these individuals to take unnecessary or excessive risks which could threaten the existence of directors, and our board of directors approved, modest increases to the salaries of our executive officers, so that their annual salaries for 2007 were as follows:Gran Tierra.

In doing so, the Compensation Committee did not use any pre-determined criteria or formulas, but rather based its decisions within that range based on its subjective assessment of the executives’ contribution to our company, our company’s operational and financial results, and our financial resources, taken as a whole.Bonus
