On October 24, 2025, Gran Tierra Energy Colombia GmbH (the "Seller"), a wholly owned subsidiary of Gran Tierra Energy Inc. (the "Company"), the Company, as guarantor, and Trafigura PTE Ltd. (the "Buyer"), entered into a crude oil sale and purchase agreement (the "Purchase and Sale Agreement") and a related prepayment addendum (the "Prepayment Addendum," and together with the Purchase and Sale Agreement, the "Oriente Crude Oil Agreements"). The Oriente Crude Oil Agreements are governed by English law.

The Purchase and Sale Agreement provides for the sale by the Seller and the purchase by the Buyer of Oriente crude oil. The Prepayment Addendum supplements the Purchase and Sale Agreement by establishing a prepayment structure under which the Buyer agreed to make available to the Seller (i) an initial advance in an aggregate amount not to exceed $150 million and (ii) an additional advance of up to $50 million, in each case, subject to certain conditions set forth therein. Amounts advanced under the Prepayment Addendum are to be satisfied through deliveries of crude oil by the Seller to the Buyer in accordance with the Purchase and Sale Agreement, with a final maturity date of four years after the date of the Prepayment Addendum.

The Prepayment Addendum provides that the Seller will apply all funds advanced thereunder to (i) repay outstanding borrowings under the Credit and Guaranty Agreement, dated April 16, 2025, among the Seller, the Company, as a guarantor, certain of the Company's indirect subsidiaries, as additional guarantors, each of the lenders that is a signatory thereto, including the Buyer, GLAS USA LLC, as administrative agent, and GLAS Americas LLC, as collateral agent, and JPMorgan Chase Bank, N.A., as calculation agent (as previously amended, supplemented or otherwise modified, the "Credit Agreement"), (ii) finance the repurchase of all or a portion of its outstanding senior notes and/or (iii) fund capital expenditures relating to certain assets owned by the Seller located in Ecuador.

The Prepayment Addendum includes financial covenants requiring the Seller to maintain (i) an asset coverage ratio of at least 150% and (ii) a debt service coverage ratio of at least 200%, tested on a semi-annual basis and upon certain other events.

The obligations of the Seller under the Prepayment Addendum are guaranteed by the Company pursuant to a deed of guarantee governed by English law.

In connection with the execution of the Oriente Crude Oil Agreements, on October 23, 2025 the Company, as guarantor, the Seller, as borrower, certain indirect subsidiaries of the Company, as additional guarantors, the lenders party thereto, including the Buyer, and GLAS USA LLC, as administrative agent, entered into an amendment and consent (the "Amendment") to the existing Credit Agreement (as thereby amended, the "Amended Credit Agreement"). The Amendment, among other things, consents to and permits Seller and the Company to execute and perform the Oriente Crude Oil Agreements, reduces the borrowing base under the Amended Credit Agreement from its then current amount to $60 million, requires the Seller to prepay outstanding loans to reduce the aggregate outstanding principal amount to no more than $20 million upon the earlier of the first disbursement under the Prepayment Addendum or January 23, 2026, and makes certain adjustments to financial covenants to account for the Oriente Crude Oil Agreements. The Amended Credit Agreement otherwise continues to be secured by the same collateral, bears the same interest rates and fees, and remains subject to the same repayment terms as were in effect prior to the Amendment. As of October 29, 2025, the outstanding balance under the Credit Agreement was $34.5 million.

The foregoing descriptions the Prepayment Addendum and the Amendment do not purport to be complete and are qualified in their entirety by reference to the full text of each such agreement, copies of which are filed as Exhibits 10.1 and 10.2 hereto and incorporated herein by reference.

Sale and Purchase Agreement.

12.1 If any of the Obligors fails to pay or discharge any amount payable by it under this Addendum or any other Prepayment Document on
its due date, interest shall accrue on the overdue amount from the due date up to the date of actual payment or discharge (both before
and after judgment) at a rate which, subject to paragraph 12.2 below,
is two per. cent. (2%) per annum higher than the rate which would have been payable if the overdue amount had, during the period of non-payment,
constituted an Advance in the currency of the Unpaid Sum for successive Surcharge Periods, each of a duration selected by the Buyer. Any
interest accruing under this Clause 12 shall be immediately payable by the Seller on demand to the Buyer.

12.2 If any Unpaid Sum consists of all or part of an Advance which became due on a day which was not the last day of a Surcharge Period
relating to that Advance:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the first Surcharge Period for that Unpaid Sum shall have a duration equal to the unexpired portion of the current Surcharge Period
relating to that Advance; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the rate of interest applying to the Unpaid Sum during that first Surcharge Period shall be two per. cent. (2%) per annum higher than
the rate which would have applied if the overdue amount had not become due.

12.3 Default interest (if unpaid) arising on an Unpaid Sum will be compounded with the Unpaid Sum at the end of each Surcharge Period applicable
to that Unpaid Sum but will remain immediately due and payable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Buyer determines that the 'Term SOFR' cannot be determined pursuant to the definition thereof; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Buyer determines that the Term SOFR rate does not adequately and fairly reflect the cost to the Buyer of making and maintaining
the Advances,

the Buyer will promptly, but in no event later than three (3) Business Days, notify the Seller. Upon notice thereof by the Buyer to the Seller, any obligation of the Buyer to make Advances shall be suspended until the Buyer revokes such notice.

make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Prepayment Document, any
amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this
Addendum or any other Prepayment Document.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Buyer shall promptly notify the Seller of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness

this Clause 13.2, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an
event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding
absent manifest error and may be made in its or their
sole discretion and without consent from any other party to this Addendum or any other Prepayment Document, except, in each case, as expressly
required pursuant to this Clause 13.2.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Notwithstanding anything to the contrary herein or in any other Prepayment Document, at any time
 (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate
 and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate
 from time to time as selected by the Buyer in its reasonable discretion or (B) the regulatory supervisor for the administrator
 of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not
 or will not be representative, then the Buyer may modify the definition of 'Surcharge Period' (or any similar or analogous
 definition) for any Benchmark settings at or after such time to remove such unavailable or non- representative tenor and
 (ii) if a tenor that was removed pursuant to Clause (i) above either (A) is subsequently displayed on
a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an
announcement that it is not or will not be representative for a Benchmark (including a Benchmark Replacement), then the Buyer may modify
the definition of 'Surcharge Period' (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate
such previously removed tenor.

---

15.1 **Definitions**

'**Tax Deduction**' means a deduction or withholding for or on account of Tax from a payment under this Addendum.

Unless a contrary indication appears, in this Clause 15 a reference to '**determines**' or '**determined**' means a determination made in the absolute discretion of the person making the determination.

15.2 **Tax gross-up** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each Obligor shall discharge all of its obligations and make all payments to be made by it without any Tax Deduction, unless a Tax
Deduction is required by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Obligor shall promptly upon becoming aware that it must make a Tax Deduction (or that there is any change in the rate or the
basis of a Tax Deduction) notify the Buyer accordingly. Similarly, the Buyer shall notify the relevant Obligor on becoming so aware in
respect of a payment payable to it.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If a Tax Deduction is required by law to be made by any Obligor, the amount of the obligation or payment due from that Obligor shall
be increased to an amount which (after making any Tax Deduction) leaves an amount equal to the obligation or payment which would have
been due if no Tax Deduction had been required.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) If any Obligor is required to make a Tax Deduction, that Obligor shall make that Tax Deduction and any payment required in connection
with that Tax Deduction within the time allowed and in the minimum amount required by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Within thirty (30) days of making either a Tax Deduction or any payment required in connection with that Tax Deduction, the relevant
Obligor shall deliver to the Buyer evidence reasonably satisfactory to the Buyer that the Tax Deduction has been made or (as applicable)
any appropriate payment paid to the relevant taxing authority.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) For the avoidance of doubt, all references to a Tax Deduction in this Clause 15.2 include, without limitation, a Tax Deduction made
for or on account of VAT.

15.3 **Tax indemnity** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Seller shall (within three (3) Business Days of demand by the Buyer) pay to the Buyer an amount equal to the loss, liability
or cost which the Buyer determines will be or has been (directly or indirectly) suffered for or on account of Tax by the Buyer in respect
of this Addendum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Paragraph (a) above shall not apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) with respect to any Tax assessed on the Buyer under the law of the jurisdiction in which the Buyer is incorporated or, if different,
the jurisdiction (or jurisdictions) in which the Buyer is treated as resident for tax purposes if that Tax is imposed on or calculated
by reference to the net income received or receivable (but not any sum deemed to be received or receivable) by the Buyer; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) to the extent a loss, liability or cost is compensated for by an increased payment under Clause 15.2 (*Tax gross-up*).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Buyer shall, upon making, or intending to make a claim under paragraph (a) above, promptly notify the Seller of the event
which will give, or has given, rise to the claim.

15.4 **Stamp taxes** 

The Seller shall pay and, within three (3) Business Days of demand, indemnify the Buyer against any cost, loss or liability that the Buyer incurs in relation to all stamp duty, registration and other similar Taxes payable in respect of this Addendum (even if by law the Buyer is required to pay any such stamp duty, registration or other similar Tax amounts itself directly). If the Buyer is required to make payment in respect of any such stamp duty, registration or other similar Tax, then the Seller shall reimburse the Buyer in full in respect of such payment within three (3) Business Days of demand.

15.5 **VAT** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) All amounts expressed to be payable under a Transaction Document by an Obligor to the Buyer which (in whole or in part) constitute
the consideration for any supply for VAT purposes are deemed to be exclusive of any VAT which is chargeable on that supply, and accordingly,
if VAT is or becomes chargeable on any supply made by the Buyer to that Obligor under a Transaction Document and the Buyer is required
to account to the relevant tax authority for the VAT, that Obligor must declare and pay on behalf of the Buyer (in addition to and at
the same time as paying any other consideration for such supply) an amount equal to the amount of the VAT (and the Buyer must promptly
provide an appropriate VAT invoice to that Obligor).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Where a Transaction Document requires any Obligor to reimburse or indemnify the Buyer for any cost or expense, that Obligor shall
reimburse or indemnify (as the case may be) the Buyer for the full amount of such cost or expense,
including such part thereof as represents VAT, save to the extent that the Buyer is entitled to credit or repayment in respect of such
VAT from the relevant tax authority.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) In relation to any supply made by the Buyer to any Obligor under this Addendum, if reasonably requested by the Buyer, that Obligor
must promptly provide the Buyer with details of that Obligor's VAT registration and such other information as is reasonably requested
in connection with the Buyer's VAT reporting requirements in relation to such supply.

respect when made or deemed to be made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) No Event of Default under paragraph (a) above will occur if the events or circumstances causing such representation or statement
to be incorrect or misleading are capable of alteration and are altered so as to make such representation or statement (if given as at
