“ANNEX B – CONTRACTED CAPACITY”

ANNEX B

DETERMINATION AND ALLOCATION OF CONTRACTED CAPACITY

1. Calculation of Contracted Capacity

(i) Before the Completion of the Delta 35 Project, for purposes of determining the number of barrels forming part of the Original Shipper’s Contracted Capacity, the following Effective Capacity per segment was used as a basis: Segment 0 – 198,000 Barrels average per day on a monthly basis; Segment 1: 575,000 Barrels average per day on a monthly basis; Segment 2: 575,000 Barrels average per day on a monthly basis; Segment 3: 375,000 Barrels average per day on a monthly basis; and for the Coveñas Terminal, the receipt of 375,000 Barrels average per day on a monthly basis coming from Segment 3, provided the Withdrawal Conditions to which the Coveñas Terminal Regulations for Technical Operating Conditions and Annex C refer are met.

(ii) If the Delta 35 Project is executed, once Completion of the Delta 35 Project occurs, the Carrier shall notify the Original Shipper in writing of: (a) its New Contracted Capacity expressed in thousands of Barrels average per day on a monthly basis in the next Effective Capacity per Segment average per day on a monthly basis, from which the 20% for the Preferential Right in favor of National Oil has already been deducted: Segment 0, 198,000 Barrels per day; Segment 1: 603,000 Barrels per day; Segment 2: 603,000 Barrels per day; Segment 3: 407,000 Barrels per day; and for the Coveñas Terminal, the receipt of 407,000 Barrels average per day on a monthly basis coming from Segment 3, provided the Withdrawal Conditions to which the Coveñas Terminal Regulations for Technical Operating Conditions \and Annex C refer are met; (b) the date as of which the additional capacity provided by the Delta 35 project will be available. If the Crude Oil nominations in exercise of the Preferential Right in favor of National Oil are less than 20% of the Delta 35 Project’s Effective Capacity, such capacity shall be part of the Available Capacity.

(iii) The Parties understand that if, either temporarily or permanently, the Effective Capacity before or after the Completion of the Delta 35 Project is greater than the capacity per Segment established in this annex for any reason, this situation shall not increase or reduce the Original Shipper’s Contracted Capacity. The difference between the Effective Capacity and the sum of the Original Shippers’ Contracted Capacities per Segment shall be part of the Available Capacity.

(iv) The Effective Capacity per Segment and therefore the Contracted Capacity of each Original Shipper was chiefly determined assuming: (i) the Design Capacity (ii) the use of Drag Reduction Agents (DRA), and (iii) that the Crude Oil transported by the Oil Pipeline is no more than 80% heavy Crude Oil, according to the specifications established in Table No.1 of this Annex and no less than 20% light or intermediate Crude Oils according to the Specifications established in Table No. 2 of this Annex.

(v) If the volume of heavy Crude Oil delivered or to be delivered exceeds the percentage limits determined above, the Effective Capacity of the Oil Pipeline may decrease, proportionally reducing the Original Shipper’s Contracted Capacity. In the event that an increase in the quantity of heavy Crude Oil delivered or to be delivered reduces the Oil Pipeline’s Effective Capacity in a given Operating Month, affecting the Contracted Capacity of the Original Shippers, the Carrier shall have the right, as long as the reduction in Effective Capacity for this reason lasts, to reduce the Contracted Capacity of the Original Shipper that delivers or plans to deliver more than 80% heavy Crude Oil, or if there are two or more Original Shippers who deliver or plan to deliver heavy Crude Oil, prorated among them, in a proportion equal to that needed to ensure that the Contracted Capacity of all other Original Shippers is not affected.

(vi) Save agreement between the Parties, the Original Shipper undertakes to withdraw the number of Barrels exceeding its Contracted Capacity in Segment 3 with respect to Segment 2 at the Vasconia Station. Breach of this obligation shall lead to the consequences established in this Contract and entitle the Carrier to receive from the Original Shipper, in Segment 2, a quantity of Crude Oil equal to that not withdrawn at the Vasconia Station, save if there is Available Capacity in Segment 3 that can be allocated to it in accordance with the Nomination Process.

(vii) The Effective Capacity of Segment 0 mentioned in (i) above prior to the signature date of the Supplementary Agreement is limited to 68,000 Barrels a day because Crude Oil with high water content is being transported, which will be suspended insofar as the Original Shipper or any Third Party needs to transport high volumes of Crude Oil by Segment 0.

(viii) The Original Shipper recognizes that the Effective Capacity by Segment mentioned in (i) and (ii) may be temporarily affected during the implementation of the Delta 35 Project and all other projects initiated by the Carrier in connection with the need to increase the Effective Capacity of the Oil Pipeline, since such projects will require scheduled shutdowns of the Oil Pipeline that will affect the Service Factor based on which the Effective Capacity mentioned in (i) and (ii) above was calculated. Without prejudice to the above, the Carrier shall make all reasonable efforts to see that the Service Factor is affected as little as possible in connection with the new projects it initiates.

(ix) The Parties understand that in order to comply with the Scheduled Capacity, the Original Shipper will have to adjust the Deliveries to the minimum and maximum daily limits indicated to it by the Carrier, after having previously coordinated with the Original Shipper insofar as possible.

2. Preferential Right

For purposes of allocating the Preferential Right, the Carrier shall observe the following rules:

(i) For all Crude Oil nominations made in exercise of the Preferential Right. For Effective Capacity equal to or less than the Effective Capacity mentioned in subparagraph 1 (i) of this Annex, the Crude Oil nominated in exercise of the Preferential Right shall be transported through the Contracted Capacity of Ecopetrol S.A. as Original Shipper or of the heirs or assignees of said Contracted Capacity.

(ii) The Crude Oil nominated in exercise of the Preferential right with respect to an Effective Capacity greater than the Effective Capacity mentioned in subparagraph 1 (i) of this Annex shall first affect the Effective Capacity exceeding the Effective Capacity mentioned in 1 (i), up to twenty percent (20%) thereof, and subsequently the Contracted Capacity of Ecopetrol S.A. as Original Shipper or the heirs and assignees of said Contracted Capacity pursuant to the above paragraph.

3. Allocation of Contracted Capacity

The Carrier shall make its Contracted Capacity for each Segment available to the Original Shipper observing the following rules for allocating the capacity:

(i) Nominations for transporting Cusiana Crude Oil made by the Original Shipper until reaching the Contracted Capacity;

(ii) Other Nominations made by the Original Shipper until reaching its Contracted Capacity.

4. Unused Contracted Capacity

The Contracted Capacity that has not been nominated by the Original Shipper for a given Operating Month shall be part of the Oil Pipeline’s Available Capacity in the respective Operating Month.

5. Quality specifications for determining Effective Capacity

(i) Table No. 1 shows the minimum and maximum quality specifications for the heavy Crude Oil that the Original Shipper shall be obligated to meet for the Deliveries to the Carrier.

In all matters related to the quality requirements for the Oil, what is established the Carrier’s Manual shall apply.

Clause Four: Annex C shall read as follows:

“ANNEX C”

PROCEDURE FOR USE OF THE COVEÑAS TERMINAL

1. For purposes of the use of the Coveñas Terminal, the rules and procedures established in this annex, as well as in the document entitled “OCENSA COVEÑAS TERMINAL OFF-TAKE PROCEDURES” shall be taken into account.

2. With respect to the Over/Under Procedure, which shall only apply to the inventories in the Coveñas Terminal, the Carrier shall not assign a Lay Day under this procedure when the time period required by the Original Shipper to return the Crude Oil that has was loaned to it for loading purposes by another Original Shipper is more than 120 days. To calculate the above time period, the Carrier shall take into account the transportation plan for the next 5 months prepared by the respective Original Shipper, as well as the term of the Contract.

3. If 180 days have elapsed since the date on which the Crude Oil was loaned and the Original Shipper has not returned it, the Original Shipper shall proceed to pay for the Crude Oil not returned, as well as the costs and expenses that must be defrayed for taxes, to the parties indicated by the Carrier. Therefore, the Original Shipper henceforth accepts that the number of Barrels that have been loaned to it shall be those established by the Carrier in the communication informing it of the payment obligation for which it is responsible. The price to be paid by the Original Shipper per Barrel not returned shall be the Declared Value or the price of the Crude Oil on the payment day calculated in the terms established for setting the Declared Value, whichever is greater. In the event of late payment, the Original Shipper shall recognize and pay delinquent interest at an annual rate of Libor +4.

Once the payment is made, the Original Shipper shall inform the Carrier with respect thereto so that said situation is reflected in the Coveñas Terminal’s inventories.

The Original Shipper recognizes that the Carrier shall not be liable for the return of or payment for the Crude Oil, as applicable.

4. Taking into account that the Coveñas Terminal is a public port, the rules established in this annex, as well as in the Off Take Procedures, shall only be in force until the Coveñas Terminal Regulations for Technical Operating Conditions are approved by the National Infrastructure Agency (hereinafter, ANI) and/or the Carrier sets new rules in this respect. Therefore, the Original Shipper understands and accepts that the Carrier is autonomous in determining the rules that will govern the use of the Coveñas Terminal.

That being the case, this Annex shall be replaced insofar as the Carrier updates or issues the applicable regulations for use of the Coveñas Terminal, including but not limited to the Coveñas Terminal Regulations for Technical Operating Conditions. For each update of this annex, the Carrier shall send the Original Shipper a notification as soon as possible, in which it shall include: (i) the date as of which the modification will apply, (ii) the modifications made and, if applicable (iii) a copy of the resolution in which the ANI authorized the modification of the Coveñas Terminal Regulations for Technical Operating Conditions.

Clause Five: Nothing indicated in this Supplementary Agreement shall be understood as a modification of the document entitled “Agreement for Capacity Release” signed on October 13, 2009 between the Ocensa Shareholders, the Original Shippers and Ocensa, as it was modified on December 11, 2009.

Clause Six: The Parties understand and accept that this Supplementary Agreement does not imply a novation of the Contract or a break in the continuity thereof.

Clause Seven: For purposes of implementing the Supplementary Agreement, the Original Shipper and the Carrier shall take into account that:

1. First Nomination under this Supplementary Agreement.

The first Nomination made after the signing date of this Supplementary Agreement (hereinafter, the “First Nomination”) shall be made on next suitable date in the nomination process, as established in the Carrier’s Manual, at which time the Contracted Capacity to which this Supplementary Agreement refers shall enter into effect.

In accordance with the above, the first Operating Month in which Oil nominated based on the Contracted Capacity will be transported shall be the second calendar month following the signing date of this Supplementary Agreement.

2. Tariff

From January 18 to January 31, 2013

For this period, the Tariff Regulations shall apply, included as Annex C of the Contract before the modification introduced by this Supplementary Agreement, only with regard to the tariff and the recognition and payment of debts.

As of February 1, 2013

The Tariff to which this Supplementary Agreement refers shall apply to the volumes scheduled to be transported as of February first (1), 2013.

3. Pending financial issues

a) In relation to the balances pending payment by the Original Shipper on December 31, 2012 in connection with the invoices for 2011 and 2012 (hereinafter the “Outstanding Invoices”), such sums of money may be paid up to January 31, 2014.

With respect to the balances, compensatory interest shall be generated and paid based on the current bank interest rate certified by the Financial Superintendence if payment is made in Colombian pesos, or the annual Libor rate +2 if payment is made in Dollars. In no case shall it exceed the lending interest rate established by Colombian law, or be less than the Consumer Price Index for the preceding calendar year. Interest shall accrue as of January 1, 2013 and the value thereof shall be invoiced monthly by the Carrier and paid by the Original Shipper in the terms established in section 4.2 of the Contract.

In any case, should a situation arise involving the Carrier’s cash requirements, the Carrier shall have the right to request payment of all or part of the Outstanding Invoices before the expiration of the term granted for that purpose. For such cases, it shall give notice of said situation to the Original Shipper, who shall have a term of thirty (30) days to pay the invoices. Once said term expires, the Carrier may exercise the rights afforded it in accordance with section 4.3 of the Contract with respect to the Outstanding Invoices for which it requested payment prior to the expiration of the granted term.

Similarly, once the term established in this Section 3 (a) for payment of the Outstanding Invoices expires (January 31, 2014), the Carrier shall be entitled to exercise the rights afforded it in accordance with section 4.3 of the Contract, for the equivalent of the sums not paid as of the aforementioned date.

Until the Original Shipper’s Outstanding Invoices, if any, have been paid in their entirety, it may not make use of the right contained in Section 6.1 (a) of the Contract, save if the assignment is made to an Affiliate.

In any case of temporary assignment, the Carrier shall have the right to terminate the Contract in the terms established in Section 5.2 (b) (iii) thereof if payment of the Outstanding Invoices is not made, an obligation with respect to which the Carrier does not release the assignor.

b) With respect to the balances pending payment by the Carrier at December 31, 2012 corresponding to other Income of the Carrier defined in the Tariff Regulations of the Contract that is modified with this Supplementary Agreement, they shall be paid to the Original Shipper no later than March 31, 2013 in the terms agreed upon between the parties.

4. All other terms established in the Supplementary Agreement shall be applicable as of the signing date hereof.
