EXECUTIVE EMPLOYMENT AGREEMENT

GRAN TIERRA ENERGY CANADA ULC, an Alberta corporation (“GTE ULC”) and GRAN TIERRA ENERGY INC., a Nevada corporation (“Gran Tierra”)

ALAN JOHNSON, an individual ordinarily resident in Calgary in the Province of Alberta

In consideration of the above and for other good and valuable consideration, including enhancements to the Executive’s entitlement to an annual bonus and increasing the amount payable to the Executive in the event the Executive’s employment is terminated without cause or terminated contemporaneously with a Change of Control (as defined below), the Parties agree as follows:

On the terms and subject to the conditions hereinafter contained, the Executive will continue in employment with GTE ULC as its VP Asset Management and as VP Asset Management of Gran Tierra. The Executive shall report to and be subject to the general direction of the President and Chief Executive Officer of Gran Tierra (the “President”) and shall undertake those duties customarily performed by a person holding the same or equivalent position in entities of a similar size, engaged in a similar business, as well as such other related duties that may be reasonably assigned by the President.

The Executive will faithfully serve the Company and will devote his full time and attention to the business and affairs of the Company and the performance of the Executive's duties and responsibilities hereunder.

The Executive shall not engage in any other business, profession or occupation which would conflict with the performance of his duties and responsibilities under this Agreement, either directly or indirectly, including accepting any appointment to the board of directors of another company without the prior written consent of the board of directors of Gran Tierra (the “Board”).

The Executive agrees that the Company may modify or remove the Executive’s assigned duties; or change the place of the Executive’s employment without additional compensation to the Executive, in accordance with the Company’s needs. The parties acknowledge and agree that any such change of duties and responsibilities will not amount to, or constitute a constructive dismissal at common law, nor provide the Executive with Good Reason, so long as the change in duties and responsibilities are comparable to the Executive’s existing duties and commensurate with the position then held by the Executive.

The Executive shall work at GTE ULC’s offices in Calgary, Alberta. The Executive shall be available for such business related travel as may be required for the purposes of carrying out the Executive’s duties and responsibilities hereunder. Such travel shall be in accordance with the Company’s travel policy as amended from time to time.

The Company will pay the Executive an annual salary of $290,000 Canadian Dollars, subject to applicable statutory deductions (the “Base Salary”). The Executive’s Base Salary will be payable in accordance with the Company’s practices and procedures as they may exist from time to time. Base Salary will be reviewed and may be increased on an annual basis.

The Executive shall be eligible to receive a target annual bonus of 45% of Base Salary in addition to the Executive’s Base Salary and other compensation for each year of the Executive’s employment (the “Bonus”).

The Bonus shall be payable by the Company shortly after the finalization of year end financials, and will be based upon factors determined by the Board, including but not limited to financial, operating, and strategic goals, and the Executive’s performance during the preceding year.

The Executive will be entitled to participate in and to receive all rights and benefits under any life insurance, disability, medical, dental, health and accident plans maintained by the Company for its employees and for its executive officers specifically. The Company will continue to pay the Executive’s Base Salary in the event that the Executive becomes disabled until such time as the Executive begins to receive short-term or long-term disability insurance benefits or a final decision is made that there is no such entitlement.

The Executive will be entitled to twenty-five (25) days’ paid vacation per year. This vacation entitlement shall be earned over the course of each year that the Executive is employed and the Executive shall be entitled to a proportionate period of vacation for any period of less than a full year of employment. The Executive will arrange vacation time to suit the essential business needs of the Company. Unused vacation entitlement in any year will be carried over into the following calendar year to a maximum entitlement of thirty (30) days in any one year. Upon termination for any reason, the Executive will be paid out any accrued but unused vacation entitlement.

Prior to the execution of this Agreement, the Executive was provided with an initial stock option grant of 200,000 shares of the common stock of Gran Tierra and 20,000 restricted stock units, in accordance with the terms and conditions of Gran Tierra’s 2007 Equity Incentive Plan (the “Plan”). The Executive will be eligible to participate in the Plan and in all applicable future stock option plans and/or incentive award plans as approved by the Board. In the event that the Executive’s employment is terminated for any reason, the Executive’s equity in the Company as well as any option grants (vested and non-vested options) in the Company, shall be governed by the terms and conditions of the Plan, without regard to any termination notice, payment in lieu of notice, or combination thereof that may be required pursuant to this Agreement or the common law.

The Executive shall be reimbursed for all reasonable out of pocket expenses incurred in the course of his employment, upon providing reasonable substantiation and appropriate receipts for such expenditures.

The Executive’s term of employment commenced on May 11, 2015 and will continue until terminated in accordance with this Article 8.

This Agreement and the Executive’s employment hereunder may be terminated, without advance notice of termination or pay in lieu of such notice, whether under contract, statute, common law or otherwise, in the following circumstances:

In the event that the Executive voluntarily resigns, except where the Executive resigns for Good Reason, the Executive will give ninety (90) days’ advance written notice. The Executive will not be entitled to receive any further compensation or benefits whatsoever other than those which have accrued up to the Executive’s last day of active service. The Company may, at its discretion, waive in whole or in part such notice by providing the Executive with payment in lieu equal to all amounts that would have been paid to the Executive for the remainder of such notice period;

The Company may terminate the employment of the Executive at any time without notice for Cause. The Executive will not be entitled to receive any further compensation or benefits whatsoever other than those which have accrued up to the Executive’s last day of active service.

"Cause" means any act or omission of the Executive which would, at common law, permit an employer to, without notice or payment in lieu of notice, terminate the employment of an employee.

In the event of the death of the Executive during the term of this Agreement, the Parties agree and acknowledge that this Agreement and the Executive’s employment hereunder will be deemed to be terminated and the Company will not be obligated to provide the Executive, or his estate, with any additional compensation excepting that which had already accrued to the Executive up to and including the date of termination, and any other death benefits that may be payable pursuant to the terms of applicable insurance coverage.

The Company may terminate the Executive’s employment without Cause at any time by providing the Executive with a separation package (the “Separation Package”) equal to one (1)

times the Base Salary and the Bonus that was paid or was payable to the Executive during the twelve (12) month period prior to the termination date. 

The Separation Package shall be payable in a lump sum within thirty (30) days of the termination date. The Executive shall not be required to mitigate any portion of the Separation Package by seeking other employment nor shall it be reduced by any remuneration or compensation earned by the Executive after the termination date.

Should the Executive terminate his employment for Good Reason, as hereinafter defined, he shall receive the Separation Package set out in section 8.3. Failure of the Executive to terminate his employment on the occurrence of any event which would constitute Good Reason shall not constitute waiver of his rights under section 8.4 or section 8.3, provided that the Executive tenders his resignation within thirty (30) days after the occurrence of the event that forms the basis for the resignation for Good Reason and provided, however, except in the event of a Change of Control (as hereinafter defined), that the Executive has provided written notice to the Company describing the nature of the event that the Executive believes forms the basis for the resignation for Good Reason, and the Company shall thereafter have ten (10) days to cure such event.

“Good Reason” is defined as the occurrence of any of the following without the Executive’s express written consent:

“Change in Control” is defined as:

In the event that this Agreement or the Executive’s employment hereunder is terminated for any reason, the Executive agrees to resign effective the termination date from any office or directorship held with or on behalf of Gran Tierra or a subsidiary, affiliated or related corporate entity (”Member Company” or “Member Companies". The Executive agrees that he shall execute any and all documents appropriate to evidence such resignations and that he will not be entitled to any additional payments or compensation of any kind as consideration for doing so.

Gran Tierra shall provide to the Executive indemnification in accordance with the Indemnification Agreement dated as of May 11, 2015 entered into between Gran Tierra and the Executive.

The provisions of sections 9.1 and 9.2 of this Agreement shall survive the termination of this Agreement or the employment of the Executive and such provisions shall continue in full force and effect in accordance with such Indemnification Agreement and the provisions of this Agreement for the benefit of the Executive.

The Executive recognizes and understands that in performing the duties and responsibilities as outlined in this Agreement, he will occupy a position of high fiduciary trust and confidence, pursuant to which he has developed and will develop and acquire wide experience and knowledge with respect to all aspects of the services and businesses carried on by Gran Tierra and its Member Companies and the manner in which such businesses are conducted. The Executive agrees that such knowledge and experience shall be used solely and exclusively in the furtherance of the business interests of Gran Tierra and its Member Companies and not in any manner detrimental to them. The Executive further agrees that so long as the Executive is employed pursuant to this Agreement, the Executive shall not engage in any practice or business in competition with the business of Gran Tierra or any of its Member Companies. The Executive further agrees that the Executive’s fiduciary duties shall survive the termination of this Agreement in accordance with applicable law.

The Executive further recognizes and understands that he is a key employee and will become knowledgeable, aware and possessed of confidential and proprietary information, know-how, data, strategic studies, techniques, knowledge and other confidential information of every kind or character relating to or connected with the business or corporate affairs and operations of Gran Tierra and its Member Companies, which may include, without limitation, geophysical studies and data, market data, engineering information, shareholder data, compensation rates and methods and personnel information (collectively “Confidential Information”) concerning the business of Gran Tierra and its Member Companies. The Executive therefore agrees that, except with the consent of the President, he will not disclose such Confidential Information to any unauthorized persons; provided that the foregoing shall not apply to any Confidential Information which is or becomes known to the public or to the competitors of Gran Tierra or its Member Companies other than by a breach of this Agreement.

Subject to this Article 10 and without otherwise restricting the fiduciary obligations imposed upon, or otherwise applicable to the Executive as a result of the Executive having been a senior officer and key employee, the Executive shall not be prohibited from obtaining employment with or otherwise forming or participating in a business competitive to the business of the Company after the termination of this Agreement and the Executive’s employment hereunder.

The Executive agrees to promptly deliver to the Company, upon termination of his employment for any reason, or at any other time when the Company so requests, all documents relating to the business of Gran Tierra or its Member Companies, including, without limitation: all reports and related data, such as summaries, memoranda and opinions relating to the foregoing, contract files, notes, records, manuals, correspondence, financial and accounting information, client lists, statistical data and compilations, patents, copyrights, trademarks, trade names, methods, processes, agreements, contacts or any other documents relating to the business of Gran Tierra or its Member Companies, and all copies thereof and therefrom (collectively, the "Business Records"). The Executive confirms that all of the Business Records which are required to be delivered to the Company pursuant to this Agreement constitute the exclusive property of Gran Tierra or its Member Companies. The obligations of confidentiality set forth in this Agreement shall continue notwithstanding the Executive’s delivery of any such documents to the Company.

Any modifications or amendments to this Agreement must be in writing and signed by all Parties or else they shall have no force and effect.

This Agreement shall enure to the benefit of and be binding upon the Parties and their respective successors and assigns, including without limitation, the Executive’s heirs, executors, administrators and personal representatives.

This Agreement shall be construed in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein. Any action arising from or relating any way to this Agreement, or otherwise arising from or relating to Executive’s employment hereunder, shall be tried in the Court of Queen's Bench situated in Calgary, Alberta. The Parties consent to jurisdiction and venue in those courts to the greatest extent possible under law.

Any notice required or permitted to be given to the Executive shall be deemed to have been received if delivered personally to the Executive or sent by courier to the Executive’s home address last known to the Company.

No failure or delay by any Party in exercising any right, power or privilege under this Agreement will operate as a waiver of those rights, powers or privileges, nor will any waiver in one instance be deemed to be a continuing waiver in any other instance.
