Scott Price, a nominee mutually acceptable to the Parties (the “Board Nominee”), and the New Nominees (Messrs. Guidry, Wade and Price, together with the New Nominees, the “Company Nominees”). West Face shall have an opportunity to review in advance the Company’s proxy statement to be filed in connection with the 2015 Annual Meeting and the Company shall in good faith consider any of West Face’s comments thereon.

(c) The Company agrees that the 2015 Annual Meeting will be held no later than June 24, 2015. In connection with the 2015 Annual Meeting, (i) the Company will recommend that the Company’s stockholders and holders of the exchangeable shares of Gran Tierra Goldstrike Inc. and Gran Tierra Exchangeco Inc. vote in favor of the election of each of the Company Nominees and the Board Nominee, solicit proxies and voting direction forms for each of the Company Nominees and the Board Nominee, and cause all Company common stock

GRAN TIERRA AND WEST FACE CAPITAL ANNOUNCE AGREEMENT

Gran Tierra Announces Expanded Board of Directors and Nominees for
2015 Annual Meeting of Stockholders

Gary Guidry Appointed President and Chief Executive Officer

CALGARY and TORONTO, May 8, 2015 - Gran Tierra Energy Inc. (Gran Tierra or the Company) (NYSE MKT: GTE, TSX: GTE), a company focused on oil exploration and production in South America, and West Face Capital Inc. (West Face) today announced that they have reached an agreement related to Gran Tierra’s 2015 Annual Meeting of Stockholders, which will be held on June 24, 2015. West Face owns approximately 9.8% of the Company’s outstanding common shares.

Under the terms of the agreement, the Gran Tierra Board of Directors will be expanded from six to eight directors, with West Face nominees immediately filling two vacant positions and two newly created ones. The West Face nominees are: Peter Dey, Robert B. Hodgins, Ronald Royal and David P. Smith. Additional West Face nominees Gary S. Guidry and Brooke Wade, continuing director J. Scott Price and a mutually agreed upon eighth director will complete the eight-member board to be nominated in the Company’s proxy materials for election at Gran Tierra’s 2015 Annual Meeting.

In addition, Mr. Guidry has been appointed President and Chief Executive Officer of Gran Tierra, effective immediately. Jeffrey Scott, previously Gran Tierra’s Executive Chair of the Board, will serve as Chairman until the 2015 Annual Meeting. Duncan Nightingale, Gran Tierra’s interim President and Chief Executive Officer, and its Chief Operating Officer until February 2015, will continue with the Company as Executive Vice President.

In connection with the agreement, West Face, among other things, has agreed to vote all of its Gran Tierra common shares in favor of each of the Company’s director nominees at the 2015 Annual Meeting.

Mr. Scott said, “The Board of Directors has acted in the best interest of the Company and its stockholders since its founding over ten years ago. Our Board has supported Gran Tierra’s growth and achievements, including the Costayaco and Moqueta discoveries as well as the Solana merger in 2008. The Board’s commitment to our stockholders also drove the changes made earlier this year to Gran Tierra’s leadership, strategy and cost structure, and our decision to engage with West Face. I am proud of what we have accomplished, and with Gary Guidry as CEO and a Board that benefits from both continuity as well as new perspectives, I believe Gran Tierra is well positioned for the next phase of its journey.”

Mr. Guidry said, “I look forward to working with the team at Gran Tierra. Its platform in Colombia is well positioned for growth and value creation.”

“We commend Gran Tierra’s Board for quickly working on a resolution in the best interests of all stockholders,” said Thomas Dea, Partner at West Face. “As the Company’s largest stockholder, we believe Gran Tierra has great potential.”

“We extend our appreciation to Gran Tierra’s retiring directors, Jeff Scott, Gerry Macey and Nick Kirton, whose dedication and counsel helped navigate the Company through the dynamic opportunities and challenges of this industry,” said Mr. Price. “We also appreciate the input we have received from our stockholders and look forward to building value on their behalf.”

The complete agreement between Gran Tierra and West Face will be filed on a Form 8-K with the Securities and Exchange Commission (the “SEC”) and with securities regulators in Canada on the System for Electronic Document Analysis and Retrieval (“SEDAR”).
