composition or characteristics of any such alternative, successor or replacement rate (including any Benchmark Replacement) will be similar to, or produce the same value or economic equivalence of, or have the same volume or liquidity as, Alternative Base Rate, the Term SOFR Reference Rate, Term SOFR or any other Benchmark prior to its discontinuance or unavailability, or (b) the effect, implementation or composition of any Conforming Changes. The Administrative Agent and each Lender, as applicable, and its respective affiliates or other related entities may engage in transactions that affect the calculation of Alternative Base Rate, the Term SOFR Reference Rate, Term SOFR, any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto, in each case, in a manner adverse to the Borrower. The Administrative Agent and each Lender, as applicable, may select information sources or services in its reasonable discretion to ascertain Alternative Base Rate, the Term SOFR Reference Rate, Term SOFR or any other Benchmark, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Lender or any other person or entity for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service.

SECTION 2
THE LOAN

2.01.Commitments. The Lenders severally agree to extend to the Borrower from time to time during the Availability Period, subject to the terms and conditions of this Agreement, one or more disbursements (the “Disbursements”) of the Loan in U.S. Dollars in a principal amount such that, at the time each Disbursement is extended by such Lender, the aggregate principal amount of such Disbursement and all previously extended Disbursements of such Lender do not exceed, in the aggregate, such Lender’s Commitment at such time nor, in the case of all Lenders, the Total Commitment at such time, as the case may be. Amounts borrowed under this Section 2.01 that are repaid or prepaid may not be re-borrowed.

2.02.Mechanics for Requesting a Disbursement. The Disbursements shall be made by the Lenders ratably in accordance with their respective Commitment at such time. The Borrower shall request a Disbursement in writing by using a request substantially in the form of Annex A hereto (the “Disbursement Request”). The Disbursement Request shall be irrevocable and binding on the Borrower and shall be given to the Administrative Agent no later than 12:00 p.m. (New York time) five (5) Business Days before the proposed Disbursement Date (or such shorter period as may be agreed by the Administrative Agent acting upon the direction of the Required Lenders). The Administrative Agent shall promptly provide to each Lender a copy of the Disbursement Request received from the Borrower.

2.03.

Funding.

(a)Subject to the terms of this Agreement, each Lender shall make available on each Disbursement Date such Lender’s Disbursement requested in the applicable Disbursement Request in immediately available funds to the Administrative Agent via Fed Wire or SWIFT, to arrive by 1:00 pm New York time to such account as may be notified from time to time by the Administrative Agent to the Lenders in writing.

(b)The Administrative Agent shall promptly transfer the proceeds funded pursuant to Section 2.03(a) in immediately available funds to the Borrower on the same day via Fed Wire or SWIFT the account designated by the Borrower in the applicable Disbursement Request.

(c)Notwithstanding any provision of this Agreement to the contrary, no Lender shall be required to make any Disbursement hereunder if, as a result thereof, the unutilized and available amount of its Commitment would thereby be exceeded or the unutilized and available Total Commitment would thereby be exceeded. The Loan is not revolving in nature; amounts borrowed and repaid or prepaid hereunder in respect of the principal amount of the Loan may not be reborrowed.

(d)The rights and obligations of the Lenders are several and not joint or joint and several. The failure of a Lender to fund any Disbursement shall not relieve any other Lender of its obligation under this Agreement to fund its Disbursement on the applicable Disbursement Date. The failure by any Lender to perform its obligations hereunder shall not affect the obligations of the Borrower towards any other party hereto nor shall any Lender or the Administrative Agent be responsible for the failure of any other Lender to advance its Disbursement.

2.04.Minimum Amounts for each Disbursement. The aggregate Disbursements under this Agreement made on any Disbursement Date shall be in a minimum amount of fifty million U.S. Dollars (U.S. $50,000,000) and in increments of one million U.S. Dollars (U.S. $1,000,000) in excess thereof.

2.05.Termination and Reduction of Commitments. The Borrower may terminate the unutilized Total Commitment, or reduce the amount thereof, by giving irrevocable written notice to the Administrative Agent not later than 5:00 P.M. on the third (3^rd) Business Day prior to the date of such termination or reduction, provided reductions of the unutilized Total Commitment shall be apportioned among the Lenders and shall reduce each Lender’s unutilized Commitment according to such ▇▇▇▇▇▇’s ratable share of the unutilized Total Commitment and shall be in the amount of U.S. $5,000,000 or in integral multiples of U.S. $1,000,000 in excess thereof. Each Lender’s Commitment and the Total Commitment will be reduced to zero at the close of business of the last day of the Availability Period.

2.06.

Notes.

(a)The Borrower’s obligation to pay the principal of and interest on the Loan to the Lenders shall be evidenced by a blank promissory note substantially in the form of Annex B (each, a “Note”). Each Note shall be valid and enforceable as to its principal amount at any time only to the extent of the amount disbursed and outstanding under the Loan evidenced thereby; and, as to interest, only to the extent of the interest accrued and unpaid thereon. Each Note shall be (i)payable to a Lender, (ii) dated the Initial Disbursement Date and (iii) payable at the date referred to in the corresponding Instructions Letter. On the Initial Disbursement Date, the Borrower shall provide to each Lender (i) a duly executed Note for such ▇▇▇▇▇▇ and (ii) a duly executed Instructions Letter substantially in the form of Annex C, pursuant to which the Borrower authorizes such Lender to complete its Note issued in accordance with this Section 2.06.

(b)In case of loss, theft, partial or complete destruction or mutilation of a Note, the affected Lender shall be entitled to request to the Borrower, and the Borrower shall promptly (but in any event within ten (10) Business Days of such notice) execute and deliver to such Lender in lieu thereof a new Note, dated the same date as the lost, stolen, destroyed or mutilated Note, in replacement of the Note; provided that, in the case of any mutilated Note, such mutilated Note shall be returned to the Borrower. Each Lender shall, prior to delivery of any replacement Note by the Borrower also comply with the procedures established by articles 802 to 821 of the Commercial Code and 398 of Law 1564 of 2012 (Código General del Proceso) or any other Applicable Law in connection with the case of loss, theft, partial or complete destruction or mutilation of a Note. In the event that any lost or stolen Note is subsequently found, such Lender shall cancel such Note and deliver such cancelled Note to the Borrower; provided further that the Borrower shall have already delivered a substitute Note to the relevant Lender. In the event of execution and delivery of a new Note as contemplated by this clause (b), such Lender shall reimburse and indemnify the Borrower for and against any and all direct liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs, expenses or disbursements of whatsoever kind or nature which may be imposed on, asserted against or incurred by the Borrower as a result of any negotiation with, or presentation by, any Person for collection of any sums due under or with respect to such ▇▇▇▇▇▇’s original Note being lost or stolen, excluding any such liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs, expenses or disbursements caused by the Borrower. All replacement Notes issued in connection with this Agreement shall be signed by an Authorized Officer of the Borrower.

(c)The payment of any part of the principal of any such Note shall discharge the obligation of the Borrower under this Agreement to pay the portion of the principal of the Loan evidenced by such Note pro tanto, and the payment of any principal of the Loan in accordance with the terms hereof shall discharge the obligations of the Borrower under the Notes evidencing the Loan pro tanto.

(d)Upon discharge of all obligations of the Borrower under the Loan, the Lenders shall cancel all the Notes and promptly return them to the Borrower.

(e)The Notes shall only be sold, assigned or transferred in accordance with the provisions of this Agreement and Applicable Law.

(f)Each Lender agrees and covenants that it will not complete or seek enforcement of its Notes other than in accordance with the instructions set forth in the corresponding Instructions Letter.

(g)In the case of a permitted assignment pursuant to Section 11.03, (i) if requested by the assignee and if any such assignment is of the aggregate Disbursement amount(s) held by the assigning Lender, the Lender shall deliver to the Borrower concurrently with the execution and delivery by the Borrower to the relevant assignee of the new Notes in the manner contemplated in clause (ii) below, the Note held by such assigning Lender evidencing such Disbursements (for any assigning Lender, together with the related Instructions Letter, the “Existing Notes” of such assigning Lender) and (ii) if requested by the assigning Lender or the relevant assignee, the Administrative Agent shall as promptly as reasonably practicable request that the Borrower, and the Borrower hereby agrees to, execute and deliver as promptly as

reasonably practicable a new Note or Notes (together with the related Instructions Letter) to such assigning Lender (if applicable) and such assignee, evidencing the Disbursement(s) held by such assigning Lender (if applicable) and such assignee (in exchange for Existing Notes to the extent such assignment is of the aggregate amount of Disbursement(s) held by the assigning Lender).

2.07.

Interest.

(a)

Interest.

(i)The Borrower agrees to pay interest in respect of the unpaid principal amount of each Disbursement from the applicable Disbursement Date until the principal amount of such Disbursement is repaid in full, at a rate per annum equal to Term SOFR for each relevant Interest Period plus the Applicable Margin.

(ii)To the extent permitted by law, interest on any due and unpaid amounts of principal or interest in respect of the Loan shall bear interest at a rate per annum equal to the rate which is 2.0% in excess of the rate borne by the Loan immediately prior to the respective payment default. The parties hereto acknowledge that, as of the Agreement Date, the payment of interest on interest (as described in this Section 2.07(a)(ii)), including default interest, is prohibited under Colombian law as currently in effect, subject to applicability of the rules set forth in Article 886 of the Commercial Code, it being understood that any outstanding interest obligations that remain unpaid for more than one (1) year may (upon the satisfaction of the rules set forth in Article 886 of the Commercial Code) be subject to interest on interest under Colombian law as currently in effect.

(iii)Interest in respect of the Loan shall be payable in arrears commencing on the date which is the sixth month anniversary of the Initial Disbursement Date and continuing on each sixth month anniversary thereof until the Maturity Date and on the Maturity Date (each, an “Interest Payment Date”), and upon the payment or prepayment of principal of the Loan (but only on the amount paid or prepaid); provided that (1) if any Interest Payment Date would fall on a day that is not a Business Day, such Interest Payment Date shall be extended to the next succeeding Business Day, unless such next succeeding Business Day would fall in the next succeeding calendar month, in which case such Interest Payment Date shall be the preceding Business Day, and (2) if any Interest Payment Date would otherwise fall after the Maturity Date, such Interest Payment Date shall be the Maturity Date.

(iv)All computations of interest hereunder shall be made on the actual number of days elapsed over a year of 360 days.

(v)On each Periodic Term SOFR Determination Day or Alternative Base Rate Term SOFR Determination Day, as applicable, the Administrative Agent shall determine Term SOFR for the relevant Interest Period and shall promptly notify the Borrower and the Lenders thereof. Each such determination shall, absent manifest error, be final and conclusive and binding on all parties hereto.

(vi)In connection with the use or administration of Term SOFR, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. The Administrative Agent will promptly notify the Borrower and the Lenders of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR. In connection with the implementation of any Conforming Changes, any reasonable discretion required to be exercised by the Administrative Agent shall be exercised after giving due consideration to the recommendations by the Relevant Governmental Body and any evolving or then-prevailing market conventions, in each case as appropriate and not with a view to obtaining a commercial advantage for the Lenders; provided, that none of the Administrative Agent or any Lender can represent, guarantee, warrant or accept any responsibility for, and shall not have any liability with respect to, the effect, implementation or composition of any Conforming Changes pursuant to this Section 2.07(a)(vi), including without limitation, whether the effect, implementation or composition of such Conforming Changes will produce the same value or economic equivalence of the interest rate applicable to the Loans or have the same volume or liquidity as it did prior to the implementation of such Conforming Changes.

(vii)In no event shall the interest applicable under this Agreement exceed the interest rate limits set forth by Applicable Law, including but not limited to, the regulations set forth by the Colombian Central Bank for loans to state-owned entities.

(b)Interest Periods. Subject to Section 2.07(a)(iii), each Interest Period shall be a six-month period; provided that:

(i)(a) (1) the initial Interest Period for the Initial Disbursement shall commence on the Initial Disbursement Date and end on the first Interest Payment Date thereafter and (2) the initial Interest Period for each Disbursement after the Initial Disbursement shall commence on its corresponding Disbursement Date and end on the immediately following Interest Payment Date; and (b) each Interest Period occurring after the initial Interest Period for each Disbursement shall commence on the day on which the next preceding Interest Period therefor expires; and

(ii)

the final Interest Period shall end on the Maturity Date.

(c)Inability to Determine Rates. Subject to Section 2.07(d), if, on or prior to the first day of any Interest Period for any SOFR Loan:

(i)the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof;

(ii)the Required Lenders determine that for any reason in connection with any request for a SOFR Loan or a conversion thereto or a continuation thereof that Term SOFR for any requested Interest Period with respect to a proposed SOFR Loan does not

adequately and fairly reflect the cost to such Lenders of making and maintaining such Loan, and the Required Lenders have provided notice of such determination to the Administrative Agent; or

(iii)the Administrative Agent (acting at the instructions of the Required Lenders) has determined that the implementation of Conforming Changes is required to permit the use and administration of the Benchmark and this Agreement has not been amended to incorporate such Conforming Changes;

then, the Administrative Agent will promptly so notify the Borrower and each Lender.

Upon notice thereof by the Administrative Agent to the Borrower, any obligation of the Lenders to make SOFR Loans, and any right of the Borrower to continue SOFR Loans or to convert Alternative Base Rate Loans to SOFR Loans, shall be suspended (to the extent of the affected SOFR Loans or affected Interest Periods) until, with respect to clause (i) and (ii) above, the Administrative Agent (with respect to clause (ii), at the instruction of the Required Lenders) revokes such notice or, with respect to clause (iii) above, this Agreement is amended in order to incorporate the relevant Conforming Changes. Upon receipt of such notice, (i) the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of SOFR Loans (to the extent of the affected SOFR Loans or affected Interest Periods) or, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to Alternative Base Rate Loans in the amount specified therein and (ii) any outstanding affected SOFR Loans will be deemed to have been converted into Alternative Base Rate Loans at the end of the applicable Interest Period. Upon any such conversion, the Borrower shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to this Section. Subject to Section 2.07(d), if the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” cannot be determined pursuant to the definition thereof on any given day, the interest rate on Alternative Base Rate Loans shall be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternative Base Rate” until the Administrative Agent revokes such determination.

(d)

Benchmark Replacement Setting.

(i)Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (a) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (b) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any

Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5^th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from the Required Lenders. If the Benchmark Replacement is Daily Simple SOFR, all interest payments will be payable on a semi-annual basis.

(ii)In connection with the use, administration, adoption or implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document, it being understood that in no event shall the interest rate determined as provided above exceed the interest rate limits set forth by the Colombian Central Bank for loans to state-owned entities.

(iii)The Administrative Agent will promptly notify the Borrower and the Lenders of (x) the implementation of any Benchmark Replacement and (y) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Administrative Agent will notify the Borrower of (A) the removal or reinstatement of any tenor of a Benchmark pursuant to Section 2.07(d)(iv) and (B) the commencement of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 2.07(d), 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 Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this Section 2.07(d).

(iv)Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (x) if the then-current Benchmark is a term rate (including the Term SOFR Reference 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 Administrative Agent 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 Administrative Agent may modify the definition of “Interest 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 (y) if a tenor that was removed pursuant to clause (x) 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 Administrative Agent may

modify the definition of “Interest Period” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor.

(v)Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any pending request for a SOFR Disbursement of, conversion to or continuation of SOFR Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a Disbursement of or conversion to Alternative Base Rate Loans. During a Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of Alternative Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of Alternative Base Rate.

2.08.Fees. The Borrower shall pay to the Administrative Agent for the account of each Lender a commitment fee, accruing from the Agreement Date through and including the last day of the Availability Period, at a rate per annum equal to 0.45% on the daily average amount of the unused and uncancelled portion of the Commitment of such Lender, payable within five (5) Business Days following (a) the date that is the six month anniversary after the Agreement Date and (b) the expiration date of the Availability Period; provided that, no commitment fees shall accrue or be payable in respect of the unused and uncancelled portion of the Commitment (for up to an amount of $665,000,000) that is used for the funding of the Initial Disbursement so long as (i) the Disbursement Request with respect to such Initial Commitment is delivered to the Administrative Agent in accordance with Section 2.02 on the Agreement Date and (ii) the disbursement of the Initial Disbursement occurs within five (5) Business Days following the Agreement Date; provided, further, that, any commitment fee accrued with respect to any of the unused Commitments of a Defaulting Lender during the period prior to the time such Lender became a Defaulting Lender and unpaid at such time shall not be payable by the Borrower so long as such Lender shall be a Defaulting Lender except to the extent that such commitment fee shall otherwise have been due and payable by the Borrower prior to such time; and provided, further, that no commitment fee shall accrue on any of the unused Commitments of a Defaulting Lender so long as such Lender shall be a Defaulting Lender.

The Borrower agrees to pay to the Joint Lead Arrangers and the Sole Bookrunner and to the Administrative Agent, as applicable, in Dollars, any and all fees payable in the amounts and at the times set forth in the JLAs Fee Letter and the Administrative Agent Fee Letter, respectively. All fees payable hereunder, under the Fee Letters and under the other Loan Documents shall be paid on the dates due, in immediately available funds, to the Joint Lead Arrangers and the Sole Bookrunner for amounts payable to the Joint Lead Arrangers and the Sole Bookrunner pursuant to the JLAs Fee Letter and to the Administrative Agent for amounts payable to the Administrative Agent pursuant to the Administrative Fee Letter. Fees paid in accordance with this Agreement, the Fee Letters and the other Loan Documents shall not be refundable under any circumstances, unless otherwise set forth in the relevant Fee Letter.

2.09.

Additional or Increased Costs.

(a)If, due to any Regulatory Change that: (i) changes the basis of taxation of any amounts payable to any Lender (other than (A) Covered Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes, and (C) Connection Income Taxes); (ii) imposes, modifies or holds applicable any reserve, special deposit, deposit insurance or similar requirement, including any compulsory loan requirement, insurance charge or other assessment (other than, for any period for which such Lender is subject to a Capital Adequacy Requirement, the reserves against “Eurocurrency liabilities” under Regulation D of the Federal Reserve Board) against assets of, deposits with or for the account of, or Loan extended by, such Lender; or (iii) imposes any other condition affecting this Agreement or the Note held by such Lender, and the effect of any of the foregoing is to increase the cost to such Lender of making its Disbursements or maintaining its proportion of the Loan or to reduce any amount received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Borrower shall from time to time, upon written demand by such ▇▇▇▇▇▇, pay to the Administrative Agent for the benefit of such Lender, additional amounts sufficient to compensate such Lender for such increased cost or reduction suffered.

(b)Each demand for payment by a Lender under this Section 2.09 shall be accompanied by a certificate showing in reasonable detail the basis for the calculation of the amounts demanded in good faith, which certificate, in the absence of manifest error, shall be conclusive and binding for all purposes. The Borrower shall pay such Lender, as the case may be, the amount shown as due on any such certificate within twenty (20) Business Days after receipt thereof.

(c)No Lender shall be entitled to demand or be compensated for any additional amounts under this Section 2.09 (i) to the extent that such additional amounts relate to any period of time more than one hundred eighty (180) days prior to the date upon which such Lender first notifies the Borrower of such additional amounts, or (ii) if such Lender is causing the incremental cost to be incurred for a reason not provided for in Section 2.09(a) above.

(d)If the Borrower is required to pay any amount to a Lender pursuant to this Section 2.09, it may prepay the portion of the Loan held by such Lender in accordance with Section 3.02. Notwithstanding anything to the contrary herein, the provisions of Sections 3.03(b) and 3.03(c) shall not apply to any such prepayment.

2.10.Breakage Costs, Other Expenses and Losses. The Borrower agrees to compensate any Lender, promptly upon its written request (which request shall set forth in reasonable detail the basis for requesting such compensation), for all reasonable and documented losses, expenses and liabilities which such Lender may sustain (including any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund its portion of the Disbursements, but excluding any loss of anticipated profits) if: (i) the Borrower fails to borrow in accordance with a Disbursement Request, (ii) the Borrower fails to make a voluntary prepayment of the Loan on an Interest Payment Date therefor in accordance with a prepayment notice given pursuant to Section 3.02, (iii) the Borrower otherwise prepays the Loan on any date other than an Interest Payment Date therefor or (iv) the assignment of a Loan by a Lender pursuant to a request by the Borrower pursuant to Section 2.12

shall occur on a day other than an Interest Payment Date. Each Lender’s calculation of the amount of compensation owing pursuant to this Section 2.10 shall be made in good faith and in a commercially reasonable manner. A ▇▇▇▇▇▇’s basis for requesting compensation pursuant to this Section 2.10 and a ▇▇▇▇▇▇’s calculation of the amount thereof made in accordance with the requirements of this Section 2.10 shall, absent manifest error, be final and conclusive and binding on all parties hereto. The Borrower shall pay such Lender, as the case may be, the amount shown as due on any such certificate within twenty (20) Business Days after receipt thereof.

2.11.Illegality. Notwithstanding any other provision herein, if after the Agreement Date the adoption of or any change in any Applicable Law or in the interpretation or application thereof by a competent Governmental Authority shall make it unlawful for any Lender to make its Disbursements or maintain its portion of the Loan as contemplated by this Agreement and the Notes, such Lender shall give notice thereof to the Administrative Agent and the Borrower describing in reasonable detail the relevant provisions of such Applicable Law, following which (a) the Commitment of such Lender shall forthwith be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances causing such suspension no longer exist and (b) if such Applicable Law shall so mandate, such ▇▇▇▇▇▇’s portion of the Loan then outstanding shall be prepaid by the Borrower on or before the date required and permitted by Applicable Law, together with all accrued interest thereon (unless actions taken pursuant to Section 2.12 shall make such prepayment unnecessary).

2.12.

Lender Replacement.

(a)(i) Upon the occurrence of any event giving rise to the operation of Section 2.09 with respect to any Lender that results in such Lender charging to the Borrower additional or increased costs, (ii) upon any adoption or change of the type described in Section 2.11, or (iii) the Borrower being required to pay Covered Taxes or additional amounts to any Lender or any Governmental Authority pursuant to Section 4.01, then such Lender shall use reasonable efforts to designate a different lending office for funding its Disbursements or booking its Loan hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment would eliminate or reduce amounts payable pursuant to Sections 2.09 or 4.01, as the case may be, in the future, or would eliminate or reduce the effect of any adoption or change described in Section 2.11 or would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable and documented costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)(i) Upon the occurrence of any event giving rise to the operation of Section 2.09 with respect to any Lender that results in such Lender charging to the Borrower additional or increased costs, (ii) upon any adoption or change of the type described in Section 2.11, (iii) in the case of a refusal by a Lender to consent to a proposed change, waiver, discharge or termination with respect to this Agreement which has been approved by the Required Lenders as provided in Section 11.06(b), or (iv) the Borrower being required to pay Covered Taxes or additional amounts to any Lender or any Governmental Authority pursuant to Section 4, the Borrower shall have the right at its sole expense and effort, if (A) no Event of Default then exists or would exist after giving effect to such replacement, (B) in the case of any such assignment

resulting from a claim for compensation under Section 2.09 or payments required to be made pursuant to Section 4, such assignment will result in a reduction in such compensation or payments and (C) in the case of any such assignment resulting from any adoption or change of the type described in Section 2.11, such assignment would eliminate or reduce the effect of any adoption or change described in Section 2.11, to replace such Lender (the “Replaced Lender”) with one or more Eligible Transferees (collectively, the “Replacement Lenders”); provided that, at the time of any replacement pursuant to this Section 2.12, each Replacement Lender shall enter into an Assignment and Assumption Agreement pursuant to Section 11.03(b)(ii), pursuant to which the Replacement Lender shall acquire the applicable portion of the Loan due to the Replaced Lender, and shall pay to the Replaced Lender in respect thereof an amount equal to the principal of, and all accrued interest on, the acquired portion of the Loan of the Replaced Lender plus all other amounts payable to Replaced Lender hereunder. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

(c)Upon the execution of the respective Assignment and Assumption Agreement, the payment of any applicable amount referred to in the proviso to Section 2.12(b), recordation of the assignment on the Register by the Administrative Agent pursuant to Section 11.03(e) and delivery to the Replacement Lender(s) of the appropriate Note(s) executed by the Borrower, each Replacement Lender shall become a Lender hereunder and the Replaced Lender shall cease to constitute a Lender hereunder, but shall continue to be entitled to any amounts that have accrued and remain unpaid prior to such assignment under Section 2.09, 2.10, Section 4 and the indemnification provisions under Sections 10.07 and 11.08 of this Agreement, each of which shall survive as to such Replaced Lender.

(c) the Borrower shall have paid in full all amounts then due under this Agreement as of such prepayment date, including interest which has accrued to the prepayment date on the amount being prepaid and any amounts under Section 2.10.

3.03.

Payments; Pro Rata Treatment.

(a)The Borrower shall make each payment hereunder or under any Note (including principal and interest) without set-off or counterclaim and not later than 12:00 p.m. (New York time) on the day when due, in Dollars, to the Administrative Agent by wire-transfer to an account outside of Colombia specified by the Administrative Agent in writing at least five (5) Business Days prior to the applicable payment date, in immediately available funds. Payments received by the Administrative Agent after 1:00 p.m. (New York time) on any Business Day shall be deemed to be received on the next Business Day.

(b)The Administrative Agent agrees that, promptly after its receipt of any payment from or on behalf of the Borrower pursuant to Section 3.03(a) above, it shall (except as otherwise expressly provided in this Agreement) distribute such payment to the Lenders pro rata based upon its respective share in the Loan, if any, of the obligations with respect to which such payment was received, provided that this clause (b) shall not apply to payments or prepayments to the Lender in connection with a claim under Sections 2.09, 2.10, 2.11 or Section 4. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, to payment of fees, indemnities, expenses and other amounts payable to the Administrative Agent in its capacity as such, (ii) second, to payment of fees, indemnities, expenses and other amounts payable to the Lenders ratably among them in proportion to the respective amounts described in this clause (ii) payable to them, (iii) third, towards payment of interest then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest then due to such parties, and (iv) fourth, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and then due to such parties.

(c)If any Lender shall, whether by voluntary payment, by realization upon security, through the exercise of any right of set-off or banker’s lien, by counterclaim or cross action or by the enforcement of any right under this Agreement or any Note, receive payment of the aggregate amount of principal or interest then due and owing to such Lender which is greater than the proportion due to such Lender, then such Lender receiving such proportionately greater payment shall (i) notify the Administrative Agent and each other Lender of the receipt of such payment and (ii) purchase (for cash at face value) participations in the Loan of other Lenders in accordance with Section 11.03(c) to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loan; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the

Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in its Loan to any assignee or participant. The Borrower consents to the foregoing. This clause (c) shall not apply to payments or prepayments to any Lender in connection with a claim under Sections 2.09, 2.10, 2.11 or Section 4.

3.04.Extension of Payment Dates. Unless otherwise provided herein, whenever any payment to the Administrative Agent or the Lenders under this Agreement or any Note shall be due (other than by reason of acceleration) on a day that is not a Business Day, the date of payment thereof shall be extended to the next succeeding Business Day.

SECTION 4
TAXES

4.01.Covered Taxes.

(a)Any and all payments by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If the Borrower shall be required by Applicable Law to withhold or deduct any Taxes from or in respect of any such sum payable to or for the benefit of the Administrative Agent or any Lender, then the Borrower shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant taxing authority or other Governmental Authority in accordance with Applicable Law and, if such Tax is a Covered Tax imposed by a Taxing Jurisdiction, then the sum payable by the Borrower shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.01) such Lender or the Administrative Agent receives an amount equal to the sum it would have received had no such deductions been made. Each Lender agrees and covenants that it will fill the blank spaces left in any Note in accordance with the corresponding Instructions Letter. For the avoidance of doubt, neither the Lenders nor the Administrative Agent will claim a higher amount under the Note for deduction or withholding for any taxes other than Covered Taxes. For Colombian income tax purposes, the Borrower represents that this Credit Agreement is deemed as public foreign indebtedness.

(b)The Borrower shall indemnify each Lender and/or the Administrative Agent for the full amount of Covered Taxes imposed by a Taxing Jurisdiction or other Governmental Authority that are payable or paid by such Lender or the Administrative Agent (including any Covered Taxes imposed by a Taxing Jurisdiction on amounts payable under this Section 4.01 arising therefrom or with respect thereto), whether or not such Covered Taxes were correctly or legally asserted. Each Lender or the Administrative Agent shall give notice to the Borrower of the assertion of any claim against such Lender or the Administrative Agent relating to its Covered Taxes as promptly as possible (and in any event within thirty (30) days) after receipt of formal written notice of such assertion, provided that failure by a Lender or the Administrative Agent to provide any such notice within ninety (90) days after receipt of formal written notice of such assertion, shall relieve Borrower of its obligation to indemnify the Lenders or the Administrative Agent pursuant to this Section 4.01. Within ten (10) Business Days of receipt of any such notice from a Lender or the Administrative Agent, the Borrower shall either:

(i)advise such Lender or the Administrative Agent that it intends to indemnify such Lender or the Administrative Agent in respect of such Covered Taxes pursuant to this paragraph (b), in which case it shall promptly indemnify in respect of such amounts, or

(ii)advise such Lender or the Administrative Agent that it intends to commence a Good Faith Contest with respect to such Covered Taxes at the Borrower’s sole cost and expense, in which case it shall promptly commence such Good Faith Contest.

(c)Except to the extent of any Good Faith Contest with respect to Covered Taxes, an indemnity made by the Borrower pursuant to this indemnification shall be made within twenty (20) Business Days after the date the relevant Lender or the Administrative Agent makes written demand therefor, which demand shall be accompanied by a certificate describing in reasonable detail the basis thereof. If the Borrower shall have commenced a Good Faith Contest with respect to any such Covered Taxes and no indemnity payment has been made to the Lender or the Administrative Agent, and such Covered Taxes are ultimately determined to be payable by the relevant Lender or the Administrative Agent in a final judicial proceeding or otherwise, the Borrower shall indemnify such Lender or the Administrative Agent for such Covered Taxes and for any other liability including penalties and interest charged by the relevant taxing authority arising therefrom or with respect thereto.

(d)Within ten (10) days after the date of any indemnification of Covered Taxes by the Borrower, the Borrower shall furnish to the Lender or the Administrative Agent the original or a certified copy of a receipt evidencing indemnification thereof or, if later, promptly after the date on which it receives such receipt and the Borrower shall promptly furnish to the Lender or the Administrative Agent any other information, documents and receipts that the Lender or the Administrative Agent may from time to time reasonably request to establish to its satisfaction that full and timely indemnification has been made of all Covered Taxes required to be indemnified under this Section 4.01.

(e)If the Administrative Agent or any Lender determines in good faith that it has finally and irrevocably received or been granted a refund in respect of any Covered Taxes as to which indemnification has been made by the Borrower pursuant to this Section 4.01, it shall within ten (10) days after the date the Administrative Agent or any Lender has received or been granted a refund, remit such refund (including any interest received in respect thereof from the relevant Governmental Authority), net of all reasonable Taxes and out-of-pocket costs and expenses payable as a result thereof, to the Borrower; provided, that the Borrower agrees to promptly return any such refund to the Administrative Agent or the relevant Lender in the event the Administrative Agent or such Lender is required to repay such refund to the relevant taxing authority. The Administrative Agent and the Lender shall provide the Borrower with a copy of any notice of assessment (or any similar documentation) from the relevant taxing authority (redacting any unrelated Confidential Information contained therein) requiring repayment of such refund. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Borrower or any other Person.

(f)If the Administrative Agent or any Lender is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document, it shall

deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, the Administrative Agent or any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. The Administrative Agent and each Lender agree that if any form or certification they previously delivered expires or becomes obsolete or inaccurate in any respect, they shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of their legal inability to do so. Notwithstanding anything to the contrary in the preceding three sentences, the completion, execution and submission of such documentation shall not be required if in the Lender's reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(g)If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by Applicable Law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such ▇▇▇▇▇▇'s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this section of the Agreement, “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(h)Each party's obligations under this Section 4 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

SECTION 6
REPRESENTATIONS AND WARRANTIES

6.01.Representations and Warranties of the Borrower. The Borrower represents and warrants, as of the Agreement Date and as of each Disbursement, that:

(a)Existence and Authority. The Borrower is duly organized and validly existing under the laws of Colombia, has all requisite power, authority and legal right to own its property and carry on its business as now conducted, and has taken all actions necessary to authorize it to execute, deliver, perform, and observe the terms and conditions of the Loan Documents.

(b)Governmental Approvals. All consents, licenses, permits, authorizations and approvals of, and exemptions by, any Governmental Authority that are necessary: (i) for the execution, delivery, performance and observance by the Borrower of the Loan Documents, including approvals relating to the availability and transfer of U.S. Dollars required to make all payments due under the Loan Documents; and (ii) for the validity, binding effect and enforceability of the Loan Documents, have, in each case, been obtained and are in full force and effect, as set forth in Section 5.01(c) and 5.02(c).

(c)Recordation. To ensure the legality, validity, enforceability, priority or admissibility in evidence in Colombia of any of the Loan Documents, it is not necessary that any of the Loan Documents be registered, recorded, enrolled or otherwise filed with any court or Governmental Authority, except as set forth in Section 5 hereof, or be notarized; or that any documentary, stamp or other similar tax, imposition or charge of any kind be paid on or in respect of any of the Loan Documents.

(d)Restrictions. The execution, delivery and performance or observance by the Borrower of the terms of, and consummation by the Borrower of the transactions contemplated by, this Agreement do not and will not conflict with or result in a breach or violation of: (i) the Estatutos Sociales of the Borrower; (ii) any law of Colombia or any other ordinance, decree, constitutional provision, regulation or other requirement of any Governmental Authority in effect as of the date on which this representation is made; or (iii) any order, writ, injunction, judgment, decree or award of any court or other tribunal. Further, the Borrower’s execution and delivery of the Loan Documents, the performance

and observance of its obligations thereunder, and the consummation of the transactions contemplated by this Agreement do not and will not conflict in any material respect with or result in a material breach of any material agreement or instrument to which the Borrower is a party or to which it or any of its revenues, properties or assets may be subject, or result in the creation or imposition of any Lien upon any of the revenues, properties or assets of the Borrower pursuant to any such material agreement or instrument.

(e)Binding Effect and Ranking. The Borrower has duly executed and delivered each Loan Document on or before the Agreement Date, other than the Note which will be delivered to the Lenders on the date of the Initial Disbursement. Each Loan Document constitutes a direct, general, and unconditional obligation of the Borrower that is legal, valid, and binding upon the Borrower and enforceable against the Borrower in accordance with its respective terms, except as such enforceability may be limited by Colombian public order laws, applicable insolvency, reorganization, liquidation, moratorium, readjustment of debt or other similar laws affecting the enforcement of creditors’ rights generally, and by the application of general principles of equity, regardless of whether such enforceability is considered in a proceeding at law or in equity. The Borrower’s payment obligations under the Loan Documents constitute the direct, general, unsecured, unsubordinated and unconditional obligations of the Borrower and rank, in all respects, at least pari passu in priority of payment with all other senior, unsecured and unsubordinated External Indebtedness of the Borrower.

(f)Choice of Law. Under the conflict of laws principles in Colombia, the choice of law provisions of this Agreement and any Note are valid, binding and not subject to revocation by the Borrower, and in any proceedings brought in Colombia for enforcement of this Agreement and any Note, the choice of the law of the State of New York as the governing law of such documents will be recognized and such law will be applied. Notwithstanding the foregoing or anything to the contrary in Section 9.01, all matters governing the authorization and execution of the Loan Documents by the Borrower are governed by and construed in accordance with the laws of Colombia.

(g)Commercial Activity. Except as provided for in (i) Articles 192, 195, 298 and 299 of Law 1437 of 2011 (Código de Procedimiento Administrativo y de lo Contencioso Administrativo), as amended by Articles 80, 81 and 87 of Law 2080 of 2021 (as amended, modified or supplemented from time to time), and (ii) Articles 593, 594 and 595 of Law 1564 of 2012 (Código General del Proceso), the Borrower acknowledges that the execution and performance of this Agreement and each other Loan Document is a commercial activity and to the extent that the Borrower has or hereafter may acquire any immunity from any legal action, suit or proceedings, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) with respect to itself or any of its property or assets, whether or not held on its own account, the Borrower hereby irrevocably and unconditionally waives and agrees not to plead or claim such immunity in respect of its obligations under this Agreement or any other Loan Document.

(h)Legal Proceedings. There are no actions, suits, litigation, arbitration or administrative proceedings pending or, to the best of the Borrower’s knowledge and belief, threatened against the Borrower which are reasonably likely to be adversely determined and, if adversely determined, could reasonably be expected to have a Material Adverse Effect.

(i)Borrower Financial Statements. The Borrower Financial Statements present fairly in all material respects the financial condition of the Borrower and its consolidated Subsidiaries at the date of such statements and the results of the operations of the Borrower and its consolidated Subsidiaries for the fiscal year or other time period to which such statements refer, in the case of unaudited Financial Statements, subject to changes resulting from audit and nominal year-end adjustments and the absence of footnotes. The Borrower Financial Statements have been prepared in accordance with IFRS consistently applied. Except as reflected in the Borrower Financial Statements, there are no liabilities or obligations with respect to the Borrower or any of its consolidated Subsidiaries of any nature whatsoever (whether absolute, accrued, contingent or otherwise, and whether or not due) for the period to which the Borrower Financial Statements relate that, either individually or in the aggregate, would be materially adverse to the Borrower. Since the date of the financial statements of the Borrower dated December 31, 2021 (audited), there has been no event, condition or circumstance that has had or could reasonably be expected to have a Material Adverse Effect, provided that changes in the oil and gas prices and any related changes in the economy or financial markets generally, whether international, national, regional or local shall not be deemed to be a Material Adverse Effect for purposes of this representation.

(j)No Corrupt Practices; Anti-Money Laundering Laws. None of the Borrower or, to the knowledge of the Borrower, any of its Subsidiaries, or any director, officer, agent, employee or other person acting on behalf of the Borrower or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the FCPA or any other applicable Anti-Corruption Law, or any Anti-Money Laundering Laws; and the Borrower and to the knowledge of the Borrower each of its Subsidiaries has implemented policies designed to promote and achieve continued compliance by the Borrower, its Subsidiaries, and their respective directors, officers, employees and agents with all Anti-Corruption Laws and Anti-Money Laundering Laws. The Borrower will not, and will take the necessary steps to prevent any Subsidiary to, directly or indirectly, use any part of the proceeds of the Disbursements, or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other Person in any manner that would give rise to a violation of any Anti- Corruption Law or Anti-Money Laundering Law.

(k)Sanctions; Office of Foreign Assets Control Regulations. None of the Borrower or, to the knowledge of the Borrower, any of its Subsidiaries or any director, officer, employee or agent of the Borrower or any of its Subsidiaries is a Sanctioned Person or to the Borrower’s knowledge is currently or has, in the past (5) years, engaged in any activity that would reasonably be expected to result in the Borrower or any Subsidiary being designated as a Sanctioned Person. The Borrower and each of its Subsidiaries has implemented policies designed to promote and achieve continued compliance by the

Borrower, its Subsidiaries and their respective directors, officers, employees and agents with applicable Sanctions. The Borrower will not use, and will take the necessary steps to prevent that any Subsidiary, directly or indirectly, uses the proceeds of the Disbursements, or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other Person: (i) to fund or facilitate any activities or business of or with any Sanctioned Person, or in any Sanctioned Country, or (ii) in any other manner that would give rise to a violation of Sanctions by any party hereto, including any Lender.

(l)No Event of Default. No Event of Default and no Potential Default has occurred and is continuing.

(m)No Material Adverse Effect. The Borrower is not aware of any information or events that have resulted, or that could reasonably be expected to result, in a Material Adverse Effect relating to the Borrower, provided that changes in the oil and gas prices and any related changes in the economy or financial markets generally, whether international, national, regional or local shall not be deemed to be a Material Adverse Effect for purposes of this representation.

(n)Compliance with Laws. Each of the Borrower and, to the knowledge of the Borrower, its Material Subsidiaries is in compliance with all Applicable Laws (including environmental laws), all Governmental Approvals held by or binding upon the Borrower or its assets and all applicable restrictions imposed by all Governmental Authorities, domestic or foreign, except (i) in the case of Anti-Corruption Law, Anti-Money Laundering Law or Sanctions, as provided in clauses (j) or (k) above, and (ii) in any other case, where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

(o)

Regulation.

(i)Investment Company. The Borrower is not an “investment company” as defined in the Investment Company Act of 1940.

(ii)Margin Stock. The Borrower is not engaged principally, or as one of its important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying “margin stock” within the meaning of Regulation U, and no part of the proceeds of the Loan will be used for the purpose, whether immediate, incidental or ultimate, of buying or carrying any such “margin stock.”

(p)

Taxes.

(i)The Borrower has timely filed or caused to be filed all material Tax returns and reports required to have been filed and has paid or caused to be paid all material Taxes required to have been paid by it, except Taxes that are contested by the Borrower on a timely basis in good faith and by appropriate proceedings and for which adequate reserves therefor have been established on the books of the Borrower in conformity with IFRS.

(ii)There are no Taxes imposed by any Governmental Authority either on or by virtue of the execution, enforcement or admissibility into evidence of any of the Loan Documents or any of the transactions thereby or on any payment to be made pursuant to any Loan Document.

(q)Validity under Colombian Law. The Loan Documents are in proper form under Colombian law for their enforcement thereof. To ensure the legality, validity or enforceability of, and the priority of the obligations incurred by the Borrower under the Loan Documents in Colombia, or establish the admissibility into evidence of any of the Loan Documents in any court in Colombia, it is not necessary that any Loan Document be filed or recorded with any Colombian governmental agency or body, or court, except for those referred to in Section 5.01(c) or Section 5.02(c), or that any stamp or similar tax be paid in Colombia on or in respect of any Loan Document for its enforcement in Colombia.

(r)Recognition of Final Judgments. A final judgment for a fixed or readily calculable sum of money rendered by any court of the State of New York or the United States of America located in the State of New York based upon any of the Loan Documents (excluding the Notes) would be declared enforceable in Colombia in the courts of Colombia against the Borrower without reexamination, review of the merits of the cause of action in respect of which the original judgment was given or re-litigation of the matters adjudicated; notwithstanding, however, that recognition of such judgment in Colombia shall be subject to Colombian procedural Applicable Laws, in particular Articles 251, 605, 606 and 607 of Law 1564 of 2012 (Código General del Proceso).

(s)Disclosure of Information. No information that has been made available to the Administrative Agent or any Lenders or the representatives or agents of the foregoing by or on behalf of the Borrower in connection with the transactions contemplated hereby, taken as a whole, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements made therein not misleading in light of the circumstances in which they are made; provided that with respect to any projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time.

(t)Properties. The Borrower has good title to, or valid leasehold interests in, all material property necessary to conduct its business as conducted from time to time in good working order and condition, except to the extent failure to do so could not reasonably be expected to have a Material Adverse Effect.

(u)Insurance. The Borrower maintains insurance with financially sound and reputable insurers against losses, damages or other risks (including, without limitation, risks and liability to Persons and property) to its assets and properties as are customarily maintained by prudent and experienced Persons engaged in the same or similar businesses operating in the same or similar jurisdictions and the Borrower deems, in its reasonable judgment, to be appropriate.

SECTION 7

Promptly but in no event later than ten (10) Business Days after the Borrower becomes aware of the occurrence of an Event of Default or of any Potential Default, furnish to the Administrative Agent written notice of the particulars of such occurrence and the corrective action proposed to be taken by the Borrower with respect thereto.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (A) any statement, warranty or representation made in or in connection with this Agreement, (B) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (C) the performance or observance of any of the covenants, agreements or other terms or conditions set

(i)Notwithstanding anything else to the contrary herein, whenever reference is made in this Agreement to any discretionary action by, consent, designation, specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or to be (or not to be) suffered or omitted by the Administrative Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the Administrative Agent, it is understood that in all cases the Administrative Agent shall be fully justified in failing or refusing to take any such action under this Agreement if it shall not have

received such written instruction, advice or concurrence of the Required Lenders or such other number or percentage of the Lenders as shall be expressly provided for herein or any agreement to which the Lenders and the Administrative Agent is a party and acting in accordance with such documents (such Lenders being referred to herein as the “Relevant Lenders”), as the Administrative Agent deems appropriate. Upon receipt of such written instruction, advice or concurrence from the Relevant Lenders, the Administrative Agent shall take such discretionary actions in accordance with such written instruction, advice or concurrence. This provision is intended solely for the benefit of the Administrative Agent and its successors and permitted assigns and is not intended to and will not entitle the other parties hereto to any defense, claim or counterclaim, or confer any rights or benefits on any party hereto.

10.03.Lack of Reliance on the Administrative Agent. Independently and without reliance upon the Administrative Agent, the Lenders, to the extent they deem appropriate, have made and shall continue to make (i) their own independent investigation of the financial condition and affairs of the Borrower in connection with the Loan and the taking or not taking of any action in connection herewith and (ii) their own appraisal of the credit worthiness of the Borrower, and the Administrative Agent and each other Lender shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any information with respect to this Agreement or the Borrower other than as expressly provided herein. Each Lender shall, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information (which may contain material, non-public information within the meaning of the United States securities laws concerning the Borrower and its Affiliates) as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder and in deciding whether or to the extent to which it will continue as a Lender or assign or otherwise transfer its rights, interests and obligations hereunder.

▇▇.▇▇.▇▇▇▇▇▇▇▇. The Administrative Agent shall be entitled to conclusively rely upon, and shall be fully protected in relying, upon any writing (including any electronic message, Internet or intranet website posting or other distribution), resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, radiogram, order or other document or telephone message signed, sent or made by any Person that the Administrative Agent believed to be the proper Person, and, with respect to all legal matters pertaining to this Agreement and its duties hereunder, upon advice of counsel selected by it. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person. In determining the compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan.

10.05.Consultation with Experts. The Administrative Agent may consult with legal counsel (who may be counsel to the Borrower), independent certified public accountants and other experts selected by it in connection with the performance of its duties hereunder and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

10.06.Compliance with Laws. The Administrative Agent shall be entitled to take any action or refuse to take any action which the Administrative Agent regards as necessary for the Administrative Agent to comply with any Applicable Law, regulation or court order.

10.07.Indemnification. To the extent the Administrative Agent is not reimbursed and indemnified by the Borrower, the Lenders will reimburse and indemnify the Administrative Agent in proportion to their respective interest (determined at the time such reimbursement or indemnity is sought) for and against any and all liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs, expenses or disbursements of whatsoever kind or nature (collectively, “Liabilities”) which may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties hereunder or in any way relating to or arising out of this Agreement; provided that no Lender shall be liable for any portion of such Liabilities resulting from the Administrative Agent’s gross negligence or willful misconduct.

10.08.The Administrative Agent in Its Individual Capacity. The Administrative Agent and the Lenders may accept deposits from, lend money to, and generally engage in any kind of banking, trust, financial advisory role or other business with the Borrower or any affiliate thereof as if it were not performing the duties specified herein, and may accept fees and other consideration from the Borrower for services in connection with this Agreement and otherwise without having to account for the same to another Lender. Notwithstanding anything to the contrary expressed or implied herein, the Administrative Agent and the Lenders shall not be bound to: (a) account to any other Person for any sum or the profit element of any sum received by it for its own account or (b) disclose to any other Person any information relating to the Borrower if such disclosure would or might in its opinion constitute a breach of any law or regulation or be otherwise actionable by suit of any Person.

10.09.

Resignation by the Administrative Agent; Successor Administrative Agent.

(a)The Administrative Agent may resign from the performance of all of its functions and duties hereunder at any time by giving thirty (30) days prior written notice (the last day of such 30-day period being referred to herein as the “Resignation Effective Date”) to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in New York, New York, or an Affiliate of any such bank with an office in New York, New York. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment by the Resignation Effective Date, then the retiring Administrative Agent may (i) (but shall not be obligated to), on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above or (ii) at the expense of the Borrower, petition a court of competent jurisdiction for the appointment of a successor; provided that in no event shall any successor Administrative Agent be a Defaulting Lender. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b)If the Person serving as Administrative Agent has, or has a direct or indirect parent company that has, (i) become the subject of a proceeding under any Debtor Relief Law, or (ii) had appointed for it a receiver, custodian, conservator, trustee, administrator, assignee for the benefit of creditors or similar Person charged with reorganization or liquidation of its business or

assets, including the Federal Deposit Insurance Corporation or any other state or federal regulatory authority acting in such a capacity, the Required Lenders may, to the extent permitted by applicable law, by notice in writing to the Borrower and such Person remove such Person as Administrative Agent and, in consultation with the Borrower, appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c)With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (i) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and (ii) except for any indemnity payments owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor's appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent's resignation or removal hereunder, the provisions of this Section 10 and Section 11.08 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting as Administrative Agent.

(d)Any entity into which the Administrative Agent in its individual capacity may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidations which the Administrative Agent in its individual capacity may be party, or any corporation to which substantially all of the corporate trust or agency business of the Administrative Agent in its individual capacity may be transferred, shall be the Administrative Agent under this Agreement without further action.

10.10.Administrative Agent May File Proof of Claim. In case of any bankruptcy or other insolvency proceeding involving the Borrower (a “Bankruptcy Proceeding”), the Administrative Agent shall be entitled (but not obligated) to intervene in such Bankruptcy Proceeding to (a) file and prove a claim for the whole amount of principal, interest and unpaid fees in respect of the Loans and all other obligations that are owing and unpaid under the terms of Agreement and other Loan Documents and to file such documents as may be necessary or advisable in order to have the claims of the Lenders and Administrative Agent (including any claim for reasonable compensation, expenses, disbursements and advances of any of the foregoing entities and their respective agents, counsel and other advisors) allowed in such Bankruptcy Proceedings; and (b) to collect and receive any monies or other property payable or deliverable on account of any such claims and to distribute the same to the Lenders under the terms of the Agreement. Further, any custodian, receiver, assignee, trustee, liquidator or similar official in any

such Bankruptcy Proceeding is (i) authorized to make payments or distributions in a Bankruptcy Proceeding directly to the Administrative Agent on behalf of all of the Lenders to whom any amounts are owed under the Agreement and other loan documents, unless the Administrative Agent expressly consents in writing to the making of such payments or distributions directly to such Lenders; and (ii) required to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under the Agreement and other Loan Documents.

▇▇.▇▇.▇▇ Amendment to Duties of Administrative Agent Without Consent. The Administrative Agent shall not be bound by any waiver, amendment, supplement or modification of this Agreement which affects its rights or duties under this Agreement unless it shall have given its prior written consent, as Administrative Agent, thereto.

10.12.

Erroneous Payments.

(a)If the Administrative Agent (x) notifies a Lender or any Person who has received funds on behalf of a Lender (any such Lender or other recipient (and each of their respective successors and assigns), a “Payment Recipient”) that the Administrative Agent has determined in its sole discretion (whether or not after receipt of any notice under immediately succeeding clause (b)) that any funds (as set forth in such notice from the Administrative Agent) received by such Payment Recipient from the Administrative Agent or any of its Affiliates were erroneously or mistakenly transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender or other Payment Recipient on its behalf) (any such funds, whether transmitted or received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and (y) demands in writing the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Administrative Agent pending its return or repayment as contemplated below in this Section 10.12 and held in trust for the benefit of the Administrative Agent, and such Lender shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two (2) Business Days thereafter (or such later date as the Administrative Agent may, in its sole discretion, specify in writing), return to the Administrative Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon (except to the extent waived in writing by the Administrative Agent) in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent in same day funds at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Administrative Agent to any Payment Recipient under this clause (a) shall be conclusive, absent manifest error.

(b)Without limiting immediately preceding clause (a), each Lender or any Person who has received funds on behalf of a Lender (and each of their respective successors and assigns), agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a

different date from, that specified in this Agreement or in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates), or (z) that such Lender or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part), then in each such case:

(i)it acknowledges and agrees that (A) in the case of immediately preceding clauses (x) or (y), an error and mistake shall be presumed to have been made (absent written confirmation from the Administrative Agent to the contrary) or (B) an error and mistake has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and

(ii)such Lender shall use commercially reasonable efforts to (and shall use commercially reasonable efforts to cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one Business Day of its knowledge of the occurrence of any of the circumstances described in immediately preceding clauses (x), (y) and (z)) notify the Administrative Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Administrative Agent pursuant to this Section 10.12(b).

For the avoidance of doubt, the failure to deliver a notice to the Administrative Agent pursuant to this Section 10.12(b) shall not have any effect on a Payment Recipient’s obligations pursuant to Section 10.12(a) or on whether or not an Erroneous Payment has been made.

(c)Each Lender hereby authorizes the Administrative Agent to set off, net and apply any and all amounts at any time owing to such Lender under any Loan Document, or otherwise payable or distributable by the Administrative Agent to such Lender under any Loan Document with respect to any payment of principal, interest, fees or other amounts, against any amount that the Administrative Agent has demanded to be returned under immediately preceding clause (a) of this Section 10.12.

(d)In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor in accordance with immediately preceding clause (a), from any Lender that has received such Erroneous Payment (or portion thereof) (and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf) (such unrecovered amount, an “Erroneous Payment Return Deficiency”), upon the Administrative Agent's notice to such Lender at any time, then effective immediately (with the consideration therefor being acknowledged by the parties hereto), (A) such Lender shall be deemed to have assigned its Loans (but not its Commitments) with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of the Loans (but not Commitments) of the Erroneous Payment Impacted Class, the “Erroneous Payment Deficiency Assignment” ) (on a cashless basis and such amount calculated at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Administrative Agent in such instance)), and is hereby (together with the Borrower) deemed to execute and deliver an Assignment and Assumption with respect to such Erroneous

Payment Deficiency Assignment, and such Lender shall deliver any Notes evidencing such Loans to the Borrower or the Administrative Agent (but the failure of such Person to deliver any such Notes shall not affect the effectiveness of the foregoing assignment), (B) the Administrative Agent as the assignee Lender shall be deemed to have acquired the Erroneous Payment Deficiency Assignment, (C) upon such deemed acquisition, the Administrative Agent as the assignee Lender shall become a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitments which shall survive as to such assigning Lender, (D) the Administrative Agent and the Borrower shall each be deemed to have waived any consents required under this Agreement to any such Erroneous Payment Deficiency Assignment, and (E) the Administrative Agent will reflect in the Register its ownership interest in the Loans subject to the Erroneous Payment Deficiency Assignment. For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitments of any Lender and such Commitments shall remain available in accordance with the terms of this Agreement.

(e)Subject to Section 11.03 (but excluding, in all events, any assignment consent or approval requirements (whether from the Borrower or otherwise)), the Administrative Agent may, in its discretion, sell any Loans acquired pursuant to an Erroneous Payment Deficiency Assignment and upon receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender shall be reduced by the net proceeds of the sale of such Loan (or portion thereof), and the Administrative Agent shall retain all other rights, remedies and claims against such ▇▇▇▇▇▇ (and/or against any recipient that receives funds on its respective behalf). In addition, an Erroneous Payment Return Deficiency owing by the applicable Lender (x) shall be reduced by the proceeds of prepayments or repayments of principal and interest, or other distribution in respect of principal and interest, received by the Administrative Agent on or with respect to any such Loans acquired from such Lender pursuant to an Erroneous Payment Deficiency Assignment (to the extent that any such Loans are then owned by the Administrative Agent) and (y) may, in the sole discretion of the Administrative Agent, be reduced by any amount specified by the Administrative Agent in writing to the applicable Lender from time to time.

(f)The parties hereto agree that (x) irrespective of whether the Administrative Agent may be equitably subrogated, in the event that an Erroneous Payment (or portion thereof) is not recovered from any Payment Recipient that has received such Erroneous Payment (or portion thereof) for any reason, the Administrative Agent shall be subrogated to all the rights and interests of such Payment Recipient (and, in the case of any Payment Recipient who has received funds on behalf of a Lender, to the rights and interests of such Lender) under the Loan Documents with respect to such amount (the “Erroneous Payment Subrogation Rights”) (provided that the Borrower's obligations under the Loan Documents in respect of the Erroneous Payment Subrogation Rights shall not be duplicative of such obligations in respect of Loans that have been assigned to the Administrative Agent under an Erroneous Payment Deficiency Assignment) and (y) an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any obligations owed by the Borrower; provided that this Section 10.12 shall not be interpreted to increase (or accelerate the due date for), or have the effect of increasing (or accelerating the due date for), the obligations of the Borrower relative to the amount (and/or timing for payment) of the obligations that would have been payable had such Erroneous Payment not been made by the

Administrative Agent; provided, further, that for the avoidance of doubt, immediately preceding clauses (x) and (y) shall not apply to the extent any such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds received by the Administrative Agent from the Borrower for the purpose of making such Erroneous Payment.

(g)To the extent permitted by applicable law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payment received, including, without limitation, any defense based on "discharge for value" or any similar doctrine.

(h)Each party's obligations, agreements and waivers under this Section 10.12 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Lender, the termination of the Commitments and/or the repayment, satisfaction or discharge of all obligations (or any portion thereof) under any Loan Document.

(i)To the extent permitted by Applicable Law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payment received, including, without limitation, any defense based on “discharge for value” or any similar doctrine.

Benefit of Agreement; Assignment; Participations.

(a)This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided, however, that (1) the Borrower may not assign or transfer any of its rights, obligations or interest under any Loan Document, except with the prior written consent of the Lenders, provided that before such

assignment is effective, the Administrative Agent shall have received from the assignee documents required to comply with its “know your customer” and anti-money laundering rules and regulations and (2) no Lender may assign or transfer any of its rights, obligations or interest under any Loan Document except in accordance with this Section 11.03 and the requirements of Applicable Law.

(b)

Any Lender may:

(i)assign all, or if less than all, a portion equal to at least U.S. $10,000,000 of the outstanding of the Loan due to it to (1) its parent company and/or any Affiliate of such Lender which is at least 50% owned by such Lender or its parent company, (2) one or more other Lenders or (3) in the case of any Lender that is a fund or trust that invests in bank loans or that manages or advises (directly or through an Affiliate) any fund or trust that invests in bank loans, any fund or trust that invests in bank loans and is managed or advised by the same investment advisor as a Lender, by an Affiliate of such investment advisor or by a Lender, as the case may be; provided that the assigning Lender shall give notice to the Borrower of any such assignment (which notice shall include the identity of the proposed assignee) fifteen (15) days prior to the effective date of such assignment in order for the Borrower to complete its internal and regulatory processes; or

(ii)assign all, or if less than all, a portion equal to at least U.S. $10,000,000 of outstanding principal amount of the Loan due to it to one or more Eligible Transferees (treating any fund that invests in bank loans and any other fund that invests in bank loans and is managed or advised by the same investment advisor as such fund or by an Affiliate of such investment advisor, as a single Eligible Transferee); and each such assignee shall become a party to this Agreement as a Lender by execution of an Assignment and Assumption Agreement;

provided that, in each case:

(w)subject to Section 2.06 (g), the assigning ▇▇▇▇▇▇ shall surrender to the Borrower the old Note(s) held by it (or furnish a standard indemnity letter from such Lender in respect of any lost Note(s) reasonably acceptable to the Borrower), and new Notes will be issued, at the Borrower’s expense, to such new Lender and to the assigning Lender (in the case of a partial assignment);

(x)so long as no Event of Default has occurred and is continuing, written consent of the Borrower shall be required in connection with any assignment pursuant to clause (ii) of this Section 11.03(b) (which consent, in each case, shall not be unreasonably withheld or delayed); provided that, the Borrower shall be deemed to have consented to an assignment unless it shall have objected thereto by written notice to the Administrative Agent within fifteen (15) Business Days after having received notice thereof;

(y)if an Event of Default has occurred and is continuing and the Administrative Agent has delivered notice thereof to the Borrower, the Borrower shall be deemed to have consented to any assignment following the date of such notice pursuant to clause (ii) of this Section 11.03(b); provided that, the assigning Lender shall be required to

give notice to the Borrower of any such assignment (which notice shall include the identity of the proposed assignee) prior to the assignee being considered a Lender in order for the Borrower to complete its internal and regulatory processes; provided further, that, failure by the Borrower to complete any such process shall not affect the validity of such assignment; and

(z)the Administrative Agent shall receive at the time of each assignment, from the assigning or assignee Lender, the payment of a non-refundable assignment fee of U.S. $5,000, which fee shall be paid by the assignee Lender.

Notwithstanding the foregoing provisions of Section 11.03(b), no such transfer or assignment (i) shall be made to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute a Defaulting Lender or a Subsidiary thereof and (ii) will be effective until recorded by the Administrative Agent on the Register pursuant to Section 11.03(e) below and the Administrative Agent shall provide notice to the Borrower of any such transfer or assignment within three (3) Business Days thereof. To the extent that an assignment of all or any portion of a Lender’s Loan pursuant to this Section 11.03(b) would, due to circumstances existing at the time of such assignment, result in increased costs under Section 2.09, 2.10 or 4.01 from those being charged by the respective assigning Lender prior to such assignment, then the Borrower shall not be obligated to pay such increased costs (although the Borrower shall be obligated to pay any other increased costs of the type described above resulting from changes after the date of the respective assignment).

(c)In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or sub-participations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent and each other Lender hereunder and interest accrued thereon. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under Applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

(d)In addition to the foregoing, any Lender may grant participations or enter into transactions with one or more Persons under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payment hereunder including without limitation any unfunded risk participation, insurance or reinsurance transaction, all in its rights hereunder without the consent of the Borrower; provided, however, that such Lender shall remain a “Lender” for all purposes hereunder and the participant shall not constitute a “Lender” hereunder and, provided further, that no Lender shall grant any participation or enter into any such transaction under which the participant or counterparty shall have direct or indirect rights to approve any

amendment to or waiver of this Agreement except to the extent such amendment or waiver would (i) extend the Maturity Date, or reduce the rate or extend the time of payment of interest or fees thereon (except in connection with a waiver of applicability of any post-Default increase in interest rates) or reduce the principal amount thereof, or (ii) consent to the assignment or transfer by the Borrower of any of its rights and obligations under any Loan Document. In the case of any such participation or transaction, the participant or counterparty shall not have any rights under any Loan Document (the participant’s counterparty’s rights against such Lender in respect of such participation to be those set forth in the agreement executed by such ▇▇▇▇▇▇ in favor of the participant or counterparty relating thereto) and all amounts payable by the Borrower hereunder shall be determined as if such ▇▇▇▇▇▇ had not sold such participation or entered into such transaction. All costs and expenses incurred in connection with the transactions contemplated in this Section 11.03(c) will be borne by the Lender entering into such transaction.

(e)Nothing in this Agreement shall prevent or prohibit any Lender from at any time pledging or assigning a security interest in all or any portion of its Loan and Notes hereunder to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank. No pledge or assignment pursuant to this clause (d) shall release the transferor Lender from any of its obligations hereunder.

(f)The Administrative Agent shall maintain at one of its offices in the United States a copy of each Assignment and Assumption Agreement delivered to it and a register for the recordation of the name and address of each Lender, and principal amounts of (and stated interest on) the Loan owing to the Lenders pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower or the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and the Lenders, at any reasonable time and from time to time upon reasonable prior notice. Upon its receipt of a duly completed Assignment and Assumption executed by an assigning ▇▇▇▇▇▇ and an assignee, the assignee's Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in clause (b) of this Section 11.03 and any written consent to such assignment required by clause (b) of this Section 11.03, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to this Agreement, the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon.

(g)Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each participant and the principal amounts of (and stated interest on) each participant’s interest in the Loan or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the

United States Treasury Regulations and Section 1.163-5(b) of the proposed United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

▇▇.▇▇.▇▇ Waiver; Remedies Cumulative. No failure or delay on the part of either the Borrower or the Administrative Agent or any Lender in exercising any right, power or privilege under any Loan Document and no course of dealing between or among the Borrower and the Administrative Agent or any Lender shall operate as a waiver of such right, power or privilege; nor shall any single or partial exercise of any right, power or privilege hereunder, under any Loan Document preclude any other right, power or privilege hereunder or thereunder. The rights and remedies expressly provided herein are cumulative and not exclusive of any rights or remedies that either the Borrower or the Administrative Agent or any Lender would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of either the Borrower or the Administrative Agent or any Lender to any other or further action in any circumstances without notice or demand.

For the avoidance of doubt, the prior approval of the

Borrower and the Ministry of Finance will not be required in connection with the implementation of any Conforming Changes unless required pursuant to Colombian public indebtedness regulations.

(b)If, in connection with any proposed change, waiver, discharge or termination of or to any of the provisions of this Agreement requiring the consent of Required Lenders and for which the consent of the Required Lenders is obtained but the consent of one or more other Lenders is not obtained, then the Borrower shall have the right, so long as all non- consenting Lenders are treated as described in clauses (A) or (B) below, to either (A) replace each such non-consenting Lender or Lenders with one or more Replacement Lenders pursuant to Section 2.12 so long as, at the time of such replacement, each such Replacement Lender consents to the proposed change, waiver, discharge or termination for which consent of the Required Lenders was obtained, or (B) repay the portion of the outstanding Loan due to such non-consenting Lender, so long as the Loan, together with accrued and unpaid interest and all other amounts, owing to such Lender are repaid concurrently with the effectiveness of such termination and at such time, unless the respective Lender continues to have an outstanding Loan hereunder, such Lender shall no longer constitute a “Lender” for purposes of this Agreement, but shall continue to be entitled to any amounts that have accrued prior to such replacement or repayment and remain unpaid under Sections 2.09, 2.10 and 4 and the indemnification under Section 10.07, which shall survive as to such replaced or repaid Lender; provided that, unless the Loan which is repaid pursuant to preceding clause (B) is immediately replaced in full at such time through the addition of new Lenders and/or outstanding Loan of existing Lenders (who in each case must specifically consent thereto), then in the case of any action pursuant to preceding clause (B), the Required Lenders (determined after giving effect to the proposed action) shall specifically consent thereto.

11.07.Counterparts; Electronic Execution. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which, when executed and delivered, shall be effective for purposes of binding the parties hereto, but all of which shall together constitute one and the same instrument. Delivery of an executed counterpart of a signature page of this Agreement by telecopy, emailed pdf or any other electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to any document to be signed in connection with this Agreement and the transactions contemplated hereby shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

This Section 11.08 shall not apply with respect to Taxes (which shall be covered by Section 4.01) other than any Taxes that represent losses, claims, damages, liabilities and related expenses arising from any non-Tax claim.

(c)To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraphs (a) and (b) of this Section 11.08, the Lenders severally agree to pay to the Administrative Agent such ▇▇▇▇▇▇’s portion of the Disbursements

(determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any sub-agent thereof).

(d)All amounts due under this Section 11.08 shall be payable not later than thirty (30) days after written demand therefor.

(e)The agreements in this Section 11.08 shall survive the resignation of the Administrative Agent, the replacement of any Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all the other obligations under this Agreement.

11.09.

Judgment Currency.

(a)The Borrower’s obligations under the Loan Documents to make payments in Dollars shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than Dollars, except to the extent that such tender or recovery results in the receipt by the Administrative Agent or any Lender of the full amount of Dollars expressed to be payable to the Administrative Agent or such Lender under the Loan Documents. If for the purpose of obtaining or enforcing judgment against the Borrower in any court or in any jurisdiction outside of Colombia, it becomes necessary to convert into or from any currency other than Dollars (such other currency being hereinafter referred to as the “Judgment Currency”) an amount due in Dollars, the conversion shall be made at the rate of exchange determined, in each case, as of the day on which the judgment is given (such Business Day being hereinafter referred to as the “Judgment Currency Conversion Date”). If, for the purpose of obtaining or enforcing judgment against the Borrower in any court in Colombia, it becomes necessary to convert into or from any Judgment Currency an amount due in Dollars, the conversion shall be made at the Colombian market representative rate certified by the Colombian Superintendence of Finance for the date of payment.

(b)If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount due by the Borrower, the Borrower covenants to pay, or cause to be paid, such additional amounts, if any (but in any event not a lesser amount), as may be necessary to ensure that the amount paid by the Borrower in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment to the Administrative Agent or such Lender by the Borrower, shall produce the amount of Dollars which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial award at the rate of exchange prevailing on the Judgment Currency Conversion Date. Any such amount of Dollars not discharged by such Borrower payment of Judgment Currency shall continue to be due as an outstanding and unpaid obligation under this Agreement and shall accrue interest at the rate then applicable to the Loan in accordance with Section 2.07 until paid in full. If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment by the Borrower of the amount due to the Administrative Agent or such Lender that results in the Borrower paying an amount in excess of that necessary to discharge or satisfy any judgment, the Administrative Agent or such Lender shall transfer or cause to be transferred to the Borrower the amount of such excess (net of any Taxes and reasonable and customary costs incurred in connection therewith).

(c)For purposes of applying the rate of exchange under this Section 11.09, the amount of Judgment Currency converted shall include any premium and costs payable in connection with the purchase of Dollars.

11.10.

English Language.

(a)If any Loan Document (or any provision of any Loan Document) other than the Notes is originally written in any language other than English, the version which is in English shall prevail in case of any discrepancy with any version in any other language.

(b)Within one hundred twenty (120) days following the Agreement Date, the Borrower will provide to the Administrative Agent official translations into Spanish of the Loan Documents requested by the Administrative Agent for use in connection with any enforcement of remedies under this Agreement and the other Loan Documents in Colombia and the Administrative Agent and the Lenders agree that such official Spanish translations shall govern for purposes of any such enforcement of remedies in Colombia, provided that for so long as the Borrower is acting in good faith to prepare such official translations, the Borrower may take up to an additional sixty (60) days after the expiration of such one hundred twenty (120) day period to complete such translations.

11.11.Severability. To the extent permitted by Applicable Law, the illegality or unenforceability of any provision of this Agreement shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Agreement.

Any Person required to maintain the confidentiality of Confidential Information as provided in this Section 11.15 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Confidential Information as such Person would accord to its own confidential information. The Borrower hereby acknowledges that any Confidential Information permitted to be shared hereunder pursuant to clauses (a), (d) or (f), subject, in the case of clause (f), to an agreement containing provisions substantially the same as those of this Section 11.15, may be made available to the Persons permitted hereby, by posting such Confidential Information on IntraLinks, Debtdomain, Syndtrak, ClearPar, or another similar electronic system.

▇▇.▇▇.▇▇ Fiduciary Duty. In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), the Borrower acknowledges and agrees that: (a) (i) the arranging and other services regarding this Agreement provided by the Administrative Agent and the Lenders are arm’s-length commercial transactions between the Borrower and its Affiliates, on the one hand, and the Administrative Agent, and the Lenders, on the other hand, (ii) the Borrower

has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (iii) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents; (b) (i) the Administrative Agent and the Lenders are and have been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, have not been, are not, and will not be acting as an advisor, agent or fiduciary for the Borrower or any of its Affiliates, or any other Person and (ii) neither the Administrative Agent nor any Lender has any obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; and (c) the Administrative Agent and the Lender and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and neither the Administrative Agent nor any Lender has any obligation to disclose any of such interests to the Borrower or its Affiliates.

11.19.Exequatur. A judgment obtained in a New York Court arising out of or relating to this Agreement, or the transactions contemplated thereby, will be enforced against the Borrower in the courts of Colombia; provided that such judgment has previously obtained an Exequatur, which is regulated by Colombian law.
