Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Each Subscription Receipt entitles the reporting person to receive from Gran Tierra Energy Inc. (the "Company"), without the payment of additional consideration or further action on the part of the reporting person and upon satisfaction of the Escrow Release Conditions (as defined below) on or before 5:00 p.m. (Toronto time) on October 31, 2016 (the "Deadline"), one share of common stock of the Company.
(2)	"Escrow Release Conditions" mean (i) other than payment of the purchase price, all conditions precedent to the completion of the acquisition of PetroLatina Energy Limited by the Company (the "Acquisition") pursuant to the purchase agreement relating to the Acquisition (the "Purchase Agreement"), as may be amended from time to time, have been satisfied in accordance with the terms of the Purchase Agreement or waived (provided that no such amendment or waiver is materially adverse to the registered owners of Subscription Receipts); and (ii) the parties to the Purchase Agreement are ready, willing and able to consummate the transactions contemplated thereby concurrent with the release of the Escrowed Funds (as defined in the subscription receipt agreement between the Company and Computershare Trust Company of Canada (the "Subscription Receipt Agreement")).
(3)	If the Escrow Release Conditions are not satisfied by the Deadline or another Termination Event (as defined in the Subscription Receipt Agreement) occurs, the reporting person will receive, instead of one share of common stock in the Company: an amount equal to the Subscription Price (as defined in the Subscription Receipt Agreement) in respect of each Subscription Receipt held, plus the reporting person's pro rata share of the Earned Interest (as defined in the Subscription Receipt Agreement), less applicable withholding taxes, all in the manner and on the terms and conditions set out in the Subscription Receipt Agreement. Upon delivery of such payment, all rights evidenced by the Subscription Receipts shall be satisfied and such Subscription Receipts shall be void and of no value or effect.
