Gran Tierra Energy Inc. 2007 Equity Incentive Plan Performance Stock Unit Award Agreement

Grant of the Award.  This Award represents your right to be issued on a future date a number of shares of Common Stock equal to the number of Performance Stock Units that vest, calculated by multiplying the portion of the Target Award eligible to vest with respect to each Performance Period by the Performance Multiplier for that Performance Period. As of the Date of Grant, the Company will credit to a bookkeeping account maintained by the Company for your benefit with the Target Award. For the avoidance of doubt, in accordance with the Plan, the Company will have the discretion to settle the Award in an amount of cash equal to the Fair Market Value of the shares of Common Stock issuable to you in respect of your Award, and any references in this Agreement to shares of Common Stock in respect of your Award shall also include an amount of cash equivalent in value to such shares, if any, that the Company elects to issue in whole or in part in settlement of your Award.

Number of Performance Stock Units and Shares of Common Stock.  The number of Performance Stock Units in your Award is set forth in the Grant Notice.

The number of Performance Stock Units that vest will be calculated by multiplying the portion of the Target Award eligible to vest with respect to each Performance Period by the Performance Multiplier for that Performance Period. The Performance Multiplier is calculated for each Performance Period based on performance metrics established and approved by the Board in its full discretion. Further details regarding the terms of the Award and some of the information that will be considered by the Board when establishing the Performance Multiplier for each Performance Period can be found in Appendix A, attached hereto.

The number of Performance Stock Units subject to your Award may be adjusted from time to time for Capitalization Adjustments as described in Section 11(a) of the Plan.

Any additional Performance Stock Units, shares of Common Stock, cash or other property that becomes subject to the Award pursuant to this Section 2 will be

No fractional Performance Stock Units or rights for fractional shares of Common Stock will be created pursuant to this Section 2.  Any fraction of a share will be rounded down to the nearest whole share.

Vesting. The Performance Stock Units will vest based on the Company’s performance during each Performance Period and your provision of Continuous Service from the Date of Grant through the date of settlement of the Award. All Performance Stock Units will be forfeited upon a termination of your Continuous Service prior to the settlement of the Award and you will have no further right, title or interest in such Award or any shares of Common Stock or cash with respect to such Award.

Date of Settlement. Subject to the satisfaction of the withholding obligations set forth in Section 11 of this Agreement, the Company will issue to you one share of Common Stock (or an amount of cash equal to the Fair Market Value of one share of Common Stock determined as of the date of settlement) for each Performance Stock Unit that vested, if any, effective December 31, 2018.

Payment by You.  This Award was granted in consideration of your services for the Company or one of its Affiliates.  Subject to Section 11 below, you will not be required to make any payment to the Company or the applicable Affiliate (other than your past and future services for the Company or the applicable Affiliate) with respect to your receipt of the Award, vesting of the Performance Stock Units, or the delivery of the shares of Common Stock underlying the Performance Stock Units.

Securities Law Compliance.  You may not be issued any Common Stock under your Award unless the shares of Common Stock are either (i) then registered under the Securities Act, or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act.  Your Award must also comply with other applicable laws, regulations and the rules of the securities exchange(s) upon which the Company’s shares are traded, and you will not receive such Common Stock if the Company determines that such receipt would not be in material compliance with such laws, regulations and rules.

Restrictive Legends.  The Common Stock issued under your Award will be endorsed with appropriate legends, if any, determined by the Company.

Transfer Restrictions.  Prior to the time that shares of Common Stock have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of the shares in respect of your Award.  For example, you may not use shares that may be issued in respect of your Performance Stock Units as security for a loan, nor may you transfer, pledge, sell or otherwise dispose of such shares.  This restriction on transfer will lapse upon delivery to you of shares in respect of your vested Performance Stock Units. Your Award is not transferable, except by will or by the laws of descent and distribution. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your

Award not a Service Contract. 

Your Continuous Service is not for any specified term and may be terminated by you or by the Company or an Affiliate at any time, for any reason, with or without cause and with or without notice. Nothing in this Agreement (including, but not limited to, the vesting of your Performance Stock Units or the issuance of the shares subject to your Performance Stock Units), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan will: (i) confer upon you any right to continue in the employment or service of, or affiliation with, the Company or an Affiliate; (ii) constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the Company of the right to terminate you at will and without regard to any future vesting opportunity that you may have.

 By accepting this Award, you acknowledge and agree that the right to vest in the Award (subject to the performance conditions enumerated in the Grant Notice and Agreement) is earned only by continuing as an employee, director or consultant at the will of the Company (not through the act of being hired, being granted this Award or any other award or benefit) and that the Company has the right to reorganize, sell, spin-out or otherwise restructure one or more of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). You further acknowledge and agree that such a reorganization could result in the termination of your Continuous Service, or the termination of Affiliate status of your employer and the loss of benefits available to you under this Agreement, including but not limited to, the termination of the right to vest in the Award.  You further acknowledge and agree that this Agreement, the Plan, the transactions contemplated hereunder and the vesting schedule set forth herein or any covenant of good faith and fair dealing that may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant for the term of this Agreement, for any period, or at all, and shall not interfere in any way with your right or the Company’s right to terminate your Continuous Service at any time, with or without cause and with or without notice.

 Unsecured Obligation.  Your Award is unfunded, and even as to any Performance Stock Units which vest, you will be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue Common Stock pursuant to this Agreement.  You will not have voting or any other rights as a stockholder of the Company with respect to the Common Stock acquired pursuant to this Agreement until such Common Stock is issued to you pursuant to Section 4 of this Agreement.  Upon such

On or before the time you receive a distribution of the shares underlying your Performance Stock Units, and at any other time as reasonably requested by the Company in accordance with applicable tax laws, you agree to make adequate provision for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any Affiliate that arise in connection with your Award (the “Withholding Taxes”). Specifically, the Company or an Affiliate may, in its sole discretion, satisfy all or any portion of the Withholding Taxes relating to your Award by any of the following means or by a combination of such means: (i) withholding from any compensation otherwise payable to you by the Company or an Affiliate; (ii) causing you to tender a cash payment; (iii) permitting or requiring you to enter into a “same day sale” commitment with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”) whereby you irrevocably elect to sell a portion of the shares to be delivered in connection with your Performance Stock Units to satisfy the Withholding Taxes and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its Affiliates; or (iv) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to you in connection with your Performance Stock Units with a Fair Market Value (measured as of the date shares of Common Stock are issued to you) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares of Common Stock so withheld will not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income; and provided further, that to the extent necessary to qualify for an exemption from application of Section 16(b) of the Exchange Act, such share withholding procedure shall be subject to the express prior approval of the Board or a duly authorized committee thereof. 

Unless the Withholding Taxes of the Company and/or any Affiliate are satisfied, the Company will have no obligation to deliver to you any Common Stock or cash with respect to this Award.

In the event the Company’s obligation to withhold arises prior to the delivery to you of Common Stock or it is determined after the delivery of Common Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount.

Dividends. You shall receive no benefit or adjustment to your Award with respect to any cash dividend, stock dividend or other distribution that does not result from a Capitalization Adjustment as provided in the Plan; provided, however, that this sentence shall not apply with respect to any shares of Common Stock that are delivered to you in connection with your Award after such shares have been delivered to you.

Other Documents.  You hereby acknowledge receipt or the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus.  In addition, you acknowledge receipt of the Company’s policy permitting officers, directors and other specified individuals to sell shares only during certain “window” periods and the Company’s insider trading policy, in effect from time to time.
