Subject to the applicable terms and conditions set out in the Arrangement Agreement:

ExchangeCo will acquire the Solana Shares held by Eligible Shareholders pursuant to the Arrangement in exchange for such number of exchangeable shares in the capital of ExchangeCo (the " Exchangeable Shares ") as is equal to the number of Solana Shares so exchanged, multiplied by the Exchange Ratio (as defined in the Arrangement); or

Gran Tierra will acquire the Solana Shares held by Ineligible Shareholders pursuant to the Arrangement in exchange for such number of shares of common stock in the capital of Gran Tierra (the " Gran Tierra Shares ") as is equal to the number of Solana Shares so exchanged, multiplied by the Exchange Ratio (as defined in the Arrangement).

Notwithstanding the foregoing, the completion of the Arrangement is subject to various conditions as set forth in the Arrangement Agreement, which conditions are for the benefit of Gran Tierra, ExchangeCo or Solana (or all of them), which Gran Tierra, ExchangeCo or Solana (or all of them) has the right to waive, in whole or in part, or to rely on in connection with the termination of the Arrangement Agreement and their respective obligations in relation to the Arrangement.

Subject to Article 5, the Shareholder agrees to support the Arrangement and to vote or cause to be voted the Subject Securities (as defined below) in favour of the Arrangement at the meeting of the holders of Solana Shares to be called to approve the Arrangement (the " Meeting ") and, in the case of Subject Securities voted by proxy, to submit the proxy for such Subject Securities in favour of the Arrangement and provide a copy thereof to Gran Tierra at least ten days prior to the date of the Meeting. For the purposes hereof, " Subject Securities " means all of the Solana Shares that the Shareholder beneficially owns or over which it exercises control or direction (the " Presently Held Securities ") and any additional Solana Shares that the Shareholder may hereafter become the beneficial owner of or exercise control or direction over (including any such Solana Shares issued on exercise of any Solana Options and Solana Warrants) (the " After Acquired Securities ").

the Shareholder is the beneficial owner of, or exercises control or direction over, the Presently Held Securities and the Shareholder has, or in the case of the After Acquired Securities will have, good and sufficient power, authority and right to transfer or cause to be transferred the legal and beneficial title to the Subject Securities to Gran Tierra or ExchangeCo, as applicable, with good and marketable title thereto free and clear of all liens, charges, encumbrances, security interests and other rights of others whatsoever; and

the Presently Held Securities represent all of the Solana Shares beneficially owned or over which the Shareholder exercises control or direction and the Shareholder does not hold any other rights to acquire any Solana Shares, other than the Solana Options and Solana Warrants set forth on the signature page hereof.
