7. | That, as a result of Ecopetrol’s internal audits and joint reviews of the Contract, the Parties are interested in including and/or modifying various provisions of the Contract, such as guarantees and commercial matters, among others. |
Taking into account the foregoing considerations, the Parties have decided to enter into this Addendum No. 4 to the Contract, which is governed by the following:
CLAUSES:
Clause 1. Add the following to Section 1.01 Definitions of Clause 1 “Definitions and Interpretation”:
“Portfolio Management” refers to the activity carried out by the Marketer that involves the termination or total or partial assignment of Supply Contracts, or the execution of new Supply Contracts, Sales Contracts, or any mechanism for participation in the MEM authorized by law and the Framework Agreement, so that it is reflected in the energy supply costs at Ecopetrol’s various boundaries.”
“Sales Contracts” means the contracts entered into between the Marketer and other MEM agents for the sale of Energy Surpluses. In the monthly settlement of the Portfolio, the proceeds from the sale of Energy Surpluses, calculated as the difference between the purchase price and the sale price of the contracted energy, shall be transferred to Ecopetrol.
“Surplus Energy” means the quantities of surplus energy represented by the Marketer, in accordance with the provisions of this contract, and the quantities of surplus energy that arise when Ecopetrol’s demand is less than the total amount of energy purchased under Supply Contracts.”
Clause 2. Add Paragraph Three to Clause 2 “Purpose of the Contract,” which shall read as follows:
“Paragraph Three: In the event that Ecopetrol excludes Fronteras in accordance with the provisions of Paragraph One above, the Supplier agrees to assign, in whole or in part, within the timeframes defined by law for the registration of contracts, the Supply Contracts, as well as any new Supply Contracts intended to meet the Ecopetrol Group’s energy demand, to Ecopetrol directly or to the marketing agent or agents designated by Ecopetrol, provided that the seller or the counterparty agrees to the full or partial assignment of the Supply Contract.
Likewise, Ecopetrol may request that the Marketer terminate the aforementioned contracts in whole or in part within the timeframes defined by law for contract registration, provided that the seller or the counterparty accepts the early termination of the contract.”
If, as a result of the assignment and/or the procedures related to the assignment, or the total or partial early termination of the aforementioned contracts, any loss is incurred by the Marketer that is not attributable to it, Ecopetrol shall hold the Marketer harmless and assume payment of such losses.”
Clause 3. Amend the paragraph of Clause 3 “Term of Execution” as follows:
“Paragraph: Upon expiration of the term of performance, the Contract shall terminate on the scheduled Termination Date, unless the Parties mutually agree in writing to extend it. Upon the Termination Date, the Marketer undertakes to transfer, within the timeframes defined by law for the registration of contracts, all existing assigned Supply Contracts, as well as new Supply Contracts intended to meet the Ecopetrol Group’s energy demand to the marketing agent or agents designated by Ecopetrol, including sales under contracts supporting such agreements.”

Clause 4. Amend Clause 5 “Method of Payment” as follows:
(a) | “The Parties shall establish a quarterly schedule setting forth the dates for settlement, billing, and payment; this schedule shall be approved by the Parties via written notice sent at least one (1) month prior to the start of the corresponding quarter. In establishing the schedule, it is important to note that Ecopetrol makes payments on Mondays, Wednesdays, and Fridays. If Monday is a holiday, payment will be made on Tuesday. It is emphasized that the Marketer must ensure and comply with the fundamental requirement that it receives the funds prior to the payment date for obligations invoiced by XM. If Ecopetrol fails to comply with this schedule and the payment date to XM is exceeded, the Marketer will invoice Ecopetrol for the applicable late payment interest as set forth in the Contract. |
(b) | Ecopetrol will make payments to the Marketer according to the schedule described in subsection (a) above, upon presentation of the invoice (physical or electronic) to Ecopetrol in accordance with the Law. At the time of invoicing, the Marketer authorized by the DIAN to issue physical (paper) invoices must submit its invoice exclusively at the Accounts Payable Coordination offices designated for that purpose. If, on the other hand, an electronic invoice is submitted, it shall be subject to the provisions of Decrees 2242 of 2015, 358 of 2020, and Resolution 000042 of May 5, 2020, which regulate the invoicing obligation. |
(c) | The invoice shall be issued using the best available information. The Parties must sign an operational agreement prior to the submission of the first invoice, in which the criteria for estimating each of the variables required for the settlement and billing of the energy service are agreed upon. In the event of adjustments or modifications to the criteria, the operating agreement must be amended by signing a new agreement between the Parties. Any resulting discrepancies between the estimated information used for the invoice and the TXF version published by ASIC must be included in subsequent invoices. |
(d) | Prior to submitting the invoice, the Marketer must send the files in Excel format or in the format agreed upon by the Parties for the review and verification of consumption and disaggregated costs at each of the borders. This allows Ecopetrol to validate the settlements made by the Marketer and approve the submission of the energy invoices. Without this information, the invoices cannot be filed. |
(e) | If Ecopetrol fails to pay any of the invoices generated under the Contract within the established term once the invoice has been officially submitted, it shall acknowledge and pay the Marketer late payment interest equivalent to the maximum statutory late payment rate determined by the competent authority. This late payment interest shall be charged on the outstanding balances in proportion to the number of days in default. |
(f) | Ecopetrol may withhold payment of all or part of any invoice from the Supplier when there are doubts or disputes regarding the accuracy of the agreed-upon amounts, but in no case may the withheld amounts exceed the amounts in dispute. Amounts that are not disputed must be paid within the timeframe set forth in this clause. No late payment interest shall accrue until disputes regarding the accuracy of the agreed-upon amounts are resolved. |
(g) | If the Marketer accepts Ecopetrol’s reasons regarding the disputed amount, the Marketer shall make the corresponding adjustment or re-invoice, and, if a balance in favor of Ecopetrol results, shall pay interest thereon at a rate equivalent to the one-month nominal IBR (Nominal Bank Reference Rate) until the date of payment. |

(i) | Notwithstanding the provisions of this clause, within one hundred fifty (150) calendar days following the invoice issuance date, either Party may notify the other of errors or discrepancies not noticed when preparing or reviewing the invoice. If, within sixty (60) calendar days following the request for invoice review, the other Party accepts the claim, the difference shall be reflected in the next invoice, and the Party responsible for covering such difference shall pay it. This adjustment shall apply proportionally from the due date of the original invoice being modified until the due date stipulated in the credit memo or adjustment invoice. If, within sixty (60) calendar days following the request for review, the other Party does not accept the claim, the dispute resolution mechanisms established in Section 24.02 shall be invoked. |
Paragraph One: Format for Submitting Invoices. Each invoice submitted by the Supplier must contain, at a minimum, the following information, which must be provided in electronic format and, where applicable, in hard copy:
i. | A total breakdown of active and reactive energy consumed and the individual cost for each Border. |
ii. | Itemized costs associated with the generation and marketing of energy. |
iii. | Itemized necessary costs for transmitting energy from the National Interconnected System to the metering points at the commercial border, and all other regulated charges established by the CREG, including the solidarity contribution charge, provided that the unregulated user is not exempt from paying it. |

viii. | Costs arising from technical diagnostics approved by Ecopetrol, in accordance with the provisions of the first paragraph of Annex 3 of the Framework Agreement. |
ix. | The bank account designated to receive payment (when the Marketer has registered more than one account). If this information is omitted, Ecopetrol will deposit the payment into the first Marketer account registered in the system. |
x. | If there are assignments or endorsements on invoices authorized by Ecopetrol, the credit transfer note, signed by the endorser, must be included. |
xi. | The physical filing of the invoice, if applicable, must be accompanied by its submission via magnetic media or electronically, including the following supporting information: the matrix of active energy, reactive energy, settlement of regulated and unregulated charges disaggregated in pesos, and re-settlement disaggregated in pesos; invoices in PDF format by Fronteras; and a report on events related to current power quality indicators. |
