We have resolved to enter into this committed credit facility agreement (the “Borrowing Agreement”), which will be governed by the following:

​

Clauses

​

I.The Loan (Committed Credit Line)

​

​

By virtue of the provisions of this Borrowing Agreement, the Lender undertakes to grant the Borrower a non-rotating committed line of credit, up to a maximum amount of ONE TRILLION COLOMBIAN LEGAL PESOS (COP$1,000,000,000,000.00) (the “Financing”), which may be disposed of by the Borrower through one or more disbursements (the “Disbursements”).”), from the date of signature of the Borrowing Agreement through December 16, 2024 inclusive (the “Availability Period”). For all purposes, this Borrowing Agreement constitutes a committed line of credit and under no circumstances shall it be understood as a revolving credit quota, so the Lender may only make Disbursements up to the

​

ECP-INFORMACION PUBLICA

Loan Contract
Ecopetrol S.A.
– Confidential –

maximum amount of the Financing, provided that the Borrower requests them within the Availability Period.

​

​

The Borrower will use the proceeds of the Financing to pay commitments arising from the Borrower’s existing credit obligations.

​

Paragraph: The Borrower’s credit obligations, financial debt obligations through credits with banks, local and international bond issuances, or any other debt of the Borrower.

​

​

Each of the Financing Disbursements will be made by the Lender within the number of business days indicated in the table included in this Section, depending on the amount of the respective Disbursement, from the fulfilment, by the Borrower, of the preceding conditions stipulated in Clause V of this Loan Agreement.

​

The table of days applicable to each Disbursement is as follows:

​

​

At the end of the Availability Period without the Borrower having requested any Disbursement or, having requested it, has not complied with the conditions precedent in the terms of this Borrowing Agreement, the Lender’s obligation with respect to the execution of any Disbursement shall cease, unless agreed in writing between the Parties, and prior authorizations, among which is that of the Ministry of Finance and Public Credit – General Directorate of Public Credit and National Treasury.

​

Paragraph: The Borrower will grant a promissory note in favor of the Lender for each Disbursement received in the development of this Loan Agreement in which the financial conditions such as the interest rate and form of payment will be stated, among others, in accordance with the model that appears as Form A of this Loan Agreement.

​

​

The Financing granted under this Borrowing Agreement will be governed by the following terms:

​

(a)Currency. The Lender will make one or more Disbursements in favor of the Borrower in Colombian legal currency, up to the maximum amount of the Financing, and the payment of the

​

ECP-INFORMACION PUBLICA

Loan Contract
Ecopetrol S.A.
– Confidential –

obligations arising from this Loan Agreement by the Borrower will be made in this same currency.

​

(b)Term. The Borrower shall repay the Financing to the Lender within five (5) years from the date the first Disbursement occurs.

​

(c)Amortization of the Capital. The Borrower must pay the entire unpaid principal of the Financing in a single installment on the date on which the fifth anniversary occurs from the date on which the first Disbursement occurs, i.e. at maturity.

​

(d)Remunerative Interest. During the Term, the Borrower will pay remunerative interest on the balance of the principal owed under this Borrowing Agreement (the “Remunerative Interest”), settled at the IBR Rate with a trading period of six (6) Months (“IBR 6 MONTHS”) certified by the Bank of the Republic, or the entity that takes its place, with two decimal places (0.00%) added to an applicable margin (spread) annual nominal year of 5.82%, with four decimal places (5.8200%) (IBR 6 MONTHS + 5.8200% Annual Nominal Semester Overdue and will be payable in its equivalent semester in arrears). In each semester, the Remunerative Interest will be adjusted taking into account the IBR 6 MONTHS in force on the start date of each Interest Period increased by the same applicable margin indicated above. The Remunerative Interest will be calculated on a basis of one year of three hundred and sixty (360) days and days effectively elapsed in the calculation period (CURRENT/360). The calculation of the Remunerative Interest (IBR 6 MONTHS in force + spread) must be truncated to four decimal places (0.0000%). For the first payment of Remunerative Interest, the IBR 6 MONTHS rate in force on the date corresponding to the first Disbursement will be taken. The Banking Reference Indicator (IBR) is a short-term reference interest rate in the Colombian interbank market, published by Banco de la República. In the event that the IBR rate is eliminated, the indicator that replaces it will be taken as the basis for settlement.

​

(e)Availability Period. The Borrower may dispose of the resources derived from the Financing, through one or more Disbursements, from the date of signing the Loan Agreement until December 16, 2024, inclusive.

​

(f)Dates of Payment of Remunerative Interest. The Borrower shall pay semi-annually, on each of the Payment Dates, the Remunerative Interest accrued during the respective Interest Period. The first payment of Remunerative Interest will be made on the First Payment Date. For all purposes under this Loan Agreement, “First Payment Date” shall be understood as the date on which six (6) months are completed, counted from the date on which the first Disbursement occurs. Subsequent payment dates will occur every six (6) months from the First Payment Date (each, a “Payment Date”), regardless of the date on which Disbursements subsequent to the first Disbursement are made. In addition, “Interest Period” means any six (6) month period beginning on a Payment Date and ending on the day (business or otherwise) immediately preceding the next Payment Date (except for the first Interest Period, which begins on the date the first Disbursement is made and ends on the day (business or otherwise) immediately preceding the First Payment Date). For clarity, the Payment Dates set forth herein shall not be affected or modified in any way by the dates on which Disbursements are made under this Borrowing Agreement, other than the first Disbursement.

​

​

(g)Default Interest. If payment of the principal due in accordance with this Borrowing Agreement is not made on the due date, the Borrower shall recognize and pay to the Lender default interest on the amount of the principal in default and for each day of delay from the day of the default until the day on which such amount is actually paid, to the rate of Remunerative Interest plus two percentage points (2%), without exceeding in any case the maximum rate allowed by law, calculated on a CURRENT/360 basis, according to which real calendar days are taken in the period of calculation of Default Interest and assumes years of 360 days, without prejudice to the corresponding legal collection actions.

​

(h)Expirations on days other than one business day. Any payment or fulfillment of any obligation arising from this Loan Agreement that must be made on days other than a business day must be understood to have been validly made on the first following business day, without this fact causing any delay or surcharge or accruing interest during the Payment Date and the day on which the payment is actually made.

​

(i)Place and method of payment. Payments for principal and interest shall be made on the dates provided for in this Borrowing Agreement and, at the Borrower’s option, shall be made to the bank account designated by the Lender for such purpose, no later than ten (10) business days prior to the respective Scheduled Payment Date, or through a debit order from an account in the Borrower’s name at Bancolombia S.A.

​

​

(a)The Borrower may at any time prepay all or part of the amounts outstanding under this Borrowing Agreement. Such advance payment will not generate the payment of any penalty, penalty, premium or any cost. In any case, the Borrower must notify the Lender of its intention to make an advance payment at least thirty (30) calendar days prior to the scheduled date of such payment.

​

(b)The parties agree to maintain the confidentiality of such Voluntary Advance Payments until such time as the Lender confirms to the Borrower receipt of such payments.

​

​

As of the date of signing this Loan Agreement, the Borrower will pay, in favor of the Lender, an availability fee equivalent to 0.025% nominal annual month in arrears plus VAT settled on the amount of the Financing not disbursed. This commission will be due per semester in arrears and is payable semi-annually in arrears during the Availability Period. The settlement of this commission will be calculated on a CURRENT/360 basis. Upon the first Disbursement, this fee will be paid on the Payment Dates (as that term is defined in Section 1.4(f) of Clause I of this Borrowing Agreement). After the Availability Period ends or when all of the Financing has been disbursed, whichever comes first, the Borrower shall not be required to pay an Availability Fee to the Lender.
