14.2 Each of the Senders shall deliver to the Transporter at a Point of Entrance a Hydrocarbon volume which, and only for purposes of Volumetric Compensation for Quality (CVC), shall be valued according to the procedure defined for the Pipeline and in accordance with its particular quality. This quality shall be determined by an independent quantity and quality inspector accepted and recognized both by the Transporter and the Sender.

14.3 Considering that as a result of the Transportation the Hydrocarbons delivered in the Pipeline are mixed without distinction, each Sender shall withdraw at the Point of Exit a volume of Hydrocarbons with a different quality than its Hydrocarbon delivered, except when it has been requested and has been accepted the Transportation of Hydrocarbons in a segregated manner. The quality of this segregated Hydrocarbon shall also be determined by an independent quantity and quality inspector accepted and recognized both by the Transporter and the Senders. This Hydrocarbon shall be assessed only for purposes of Volumetric Compensation for Quality and shall take into account the compensation for quality due to the interfaces occurring when transported with other Crude Oils.

14.4 The Transporter shall apply the mechanism of Volumetric Compensation for Quality defined by the same for the Pipeline which shall have the following main characteristics:

14.4.1 The Senders who have delivered to the Transporter Hydrocarbons with a better quality than the mixed Hydrocarbon withdrawn at the Point of Exit of the Pipeline shall be entitled to compensation in volume, equivalent to the volumes that Senders who have delivered Hydrocarbons of lower quality than the ones withdrawn at the Point of Exit will have to assume. For such purpose, individual qualities of all volumes delivered and withdrawn shall be taken into account as well as the final inventories of the preceding month of Operation and the last month of Operation, with its respective qualities.

Operation and Transport Regulations

Version 1

14.4.2 The Volumetric Compensation for Quality shall be internal between the Senders in such a way that the final volumetric balances equal cero and the Transporter shall neither charge nor Pay any volume for this purpose and shall only serve as a mediator, regulator, liquidator and responsible for the volumetric distribution of the compensations.

14.4.3 The Volumetric Compensation for Quality is not part of the Rate and therefore shall not be compensated or will have any variation as a result of this.

14.5 In each month of Operation the Transporter shall make a balance of the existing volumes and qualities at the beginning of the month delivered to the Pipeline, lost, withdrawn and existing at the end of the month, both for the total of Hydrocarbons as well as for individual Hydrocarbons of each Sender.

14.6 The Sender shall hold the Transporter and owner harmless against any cost, action, claim, intended procedures by any Third parties, losses and all damage and obligations incurred and inherent to the mix of Hydrocarbons in the Transportation process and the Volumetric Compensation for Quality.

14.7 In any case the Transporter may modify the mechanism of Volumetric Compensation for Quality contained herein, in the respective annexes and all other documents in connection with the CVC.

14.8 Senders of a specific Hydrocarbon may agree with the Transporter not to apply the Volumetric Compensation for Quality to said Hydrocarbon. The foregoing shall be applicable as long as the Hydrocarbon of other Senders is not affected negatively.

14.9 By agreement between the totality of Senders and the Transporter, it may be decided not to implement the Volumetric Compensation for Quality (CVC) for Crude Oils transported through the system. In this case the Transporter may implement any other mechanism validated with the Senders to carry out the volumetric balances.

Operation and Transport Regulations

Version 1

ANNEX 1: MECHANISMS OF QUALITY COMPENSATION FOR THE MIXTURE OF CRUDE OIL

ADJUSTMENT PROCEDURES OR VOLUMETRIC BALANCES

The Transporter shall conduct the volumetric balance with a monthly frequency in order to establish the volumes injected by each Sender to the Pipeline, the identifiable losses, the Non-identifiable losses, consumptions, inventory variations, and any adjustments for quality if the latter is applicable.

LOSSES

For purposes of the procedure hereof, the provisions set out in the Manual of the Transporter for handling Losses in the Pipeline and in the annex hereof shall be applied.

CRUDE OIL CONSUMPTION

The Transporter assumes the totality of costs for consumption of Crude Oil.

VOLUMETRIC COMPENSATION FOR QUALITY – CVC

3.1

When Crude Oils are delivered to the Pipeline of different quality and from different Senders, the result shall be a Crude Oil with different characteristics of quality and market value than the Crude Oil delivered to the Pipeline by each of the Senders. Due to different qualities of Crude Oil delivered to the Pipeline, some Senders shall withdraw Crude of higher value than the Oil delivered while others shall withdraw Crude Oil with less value than the Oil delivered to the Pipeline.

In order to make equitable adjustments between the Senders of the Pipeline by the differences in value resulting for differences in quality of Crude Oils delivered I the Pipeline, a procedure of volumetric compensation for quality shall be established (“CVC” in Spanish).

The purpose of the CVC is to establish a system to compensate Senders for the degradation or improvement of the Crude Oil withdrawn compared with the Crude delivered. The Sender withdrawing a Crude o lower quality than the Crude delivered shall be compensated with a higher volume. The Sender withdrawing a Crude with higher quality than the Crude delivered shall compensate others Senders of better quality accepting a lower volume. At any rate, the sum of debits and credits by CVC for all Senders shall be cero.

Operation and Transport Regulations

Version 1

At any node of Entrance of the Pipeline where two or more Crude Oil flows merge in order to be transported, a volumetric compensation for quality shall be established on the resulting mix.

3.2

SAMPLING AND SYSTEM MEASUREMENT

For purposes of the procedure hereof, the provisions in the Manual of the Transporter shall be applied for measurements in the Pipeline.

3.3

CVC PROCEDURES

The Transporter set out detailed procedures for the CVC following the guidelines established hereto.

3.3.1

The Transporter shall administer the CVC process and the Senders may audit the process or request reviews thereto as long as the Transporter is timely informed and a working plan is coordinated between the parties.

3.3.2

The Transporter shall establish monthly the coefficients for adjustments of quality and sulfur pursuant to the criteria established herein.

3.3.3

The CVC shall be settled in kind.

3.3.4

The Transporter shall make monthly adjustments to the corresponding volume of Crude to each Sender, based on the coefficients of adjustment for quality.

For any month of Operation the corresponding quantity of Crude of each Sender shall be:

(a)

Reduced if such Sender of the Pipeline delivers Crude of lower quality than the average quality of the mix,

(b)

Increased if said Sender of the Pipeline delivers Crude of ah higher quality than the average quality of the mix.

3.3.5

At the latest on the 15th day of the calendar month following the Operation, Senders shall report to the Transporter the export prices, the API gravity and the sulfur content of its Crude for the Month of Operation.

Operation and Transport Regulations

Version 1

3.3.6

Each month of Operation the Transporter shall measure the volumes delivered by the Senders and shall determine the weighted average for the quality parameters of Crude Oils delivered.

3.3.7

The Transporter shall calculate the adjustments to the volume for each Sender and shall determine the Crude volume that corresponds. No adjustment in the volume as a consequence of the CVC shall affect the Transportation fee that a Sender shall Pay to the Transporter.

3.3.8

Senders acknowledge that adjustments to their Crude volumes to be withdrawn as a result of these principles and procedures of the CVC may affect the volume of Crude Oil for a withdrawal afterwards.

3.3.9

Senders are entitled to review the Transporter’s calculations regarding the adjustments by CVC and the due application of this procedure.

The parties may jointly review:

(a)

The appropriateness of the Crude Oil reference basket regarding their terms of quality.

(b)

The information on prices available to the public.

(c)

The calculations of the coefficients and the volumes adjusted.

3.3.10

A data base for the API gravity shall be developed and sulfur content for Crude delivered from reliable samples of laboratory of Crude Oil flows. The quality data of Crude Oil must comply with the following criteria:

The API gravity and the sulfur content on the data base of the Crude quality are representative of the current qualities of Crude which is being delivered.

The variability of the API gravity and sulfur is within an allowed tolerance to be determined by the parties. Analyses of sulfur content shall be conducted based on a schedule agreed by the parties after the beginning of the Fiscal Year.

3.4

METHODOLOGY FOR CRUDE OIL VALUATION

By means of using the Crude Oil basket of reference the variation of price shall be determined regarding the API grade and sulfur content for Crude Oil delivered. The method is based on the use of the linear regression of prices of a Crude Oil basket of reference delivered in the coast of the Gulf of The United States of America with API gravity and sulfur content.

Operation and Transport Regulations

Version 1

3.4.1

BASKET OF REFERENCE FOR CRUDE OIL

The basket of Crude Oil to be used shall always include a minimum of ten (10) Crude Oils. The basket of reference for Crude Oil with prices and qualities historically recognized shall be used to determine the coefficients of adjustment for API grade and sulfur content. The price information of the basket shall be continuously available from sources open to the public for each Crude Oil of reference. Prices reported used in the basket of Crude Oil of reference shall be obtained from independent price information services recognized by the industry and shall come from real Operations.

This basket provides a range of qualities to develop the coefficients for the regressions and therefore cover the flows that may be injected to the Pipeline. The initial basket of Crude Oils to be used is the one established in table I of this procedure which may be reviewed by common agreement between the Transporter and the Senders.

3.4.2

CALCULATION OF CRUDE OIL PRICES FOR THE BASKET IN THE COAST OF THE GULF

All price quotes of Crude Oil for a common location in the Coast of the Gulf of The United States of America shall be adjusted.

All prices of Crude Oil of reference shall be adjusted with respect to the location and based on the availability of price information according to the following list:

FOB quotation

Transportation to the Coast of the Gulf of The United States of America is added using the appropriate vessel size.

Customs Tariffs, Oil pollution Liability Insurance, “Superfund” taxes are included and others as appropriate.

CIF quotation

Customs Tariffs, Oil pollution Liability Insurance, “Superfund” taxes are included and others as appropriate.

Crude Oil delivered by the Pipeline

Any Pipeline fee is added if necessary

“Superfund” is included and other fees/tariffs as appropriate.

Tables II to IV of this procedure show examples for calculation of basket Crude prices delivered in the Gulf Coast.

3.4.3

LINEAR REGRESSION FOR PRICES, GRAVITY AND SULFUR

To determine API gravity and sulfur coefficients linear regressions shall be run using the minimum square method.

Operation and Transport Regulations

Version 1

First the arithmetic average is calculated for prices of the basket of Crude Oils of reference delivered in the Gulf coast for three months. The cumulative average for three months shall be calculated at the closing of the settling month using the prices for the settling month and the two (2) previous months prior to the settling month (See 1 in table V).

To determine the API gravity coefficient, a linear regression analysis shall be performed using the three months average of Crude prices from the basket calculated in the paragraph above as the dependent variable. Likewise, the API gravity and sulfur content is used for each Crude Oil of reference as the independent variables. The formula to be used makes a regression of the price as a function of API gravity and sulfur simultaneously (See 2 in table V).

To determine the sulfur content a linear regression analysis shall be conducted using the three month average of Crude prices from the basket calculated in the previous paragraph as the dependent variable. Likewise, the API gravity and sulfur content is used for each Crude Oil of reference as the independent variables. The formula to be used makes a regression of the price as a function of API gravity and sulfur simultaneously (See 3 in table V).

The results of the determination of the linear relation between the price delivered and the API gravity and sulfur content may be stated in the following lineal equation:

Y = A1* X1+ B* X2 + b

Pr = A1* APIR+ B*SR + b (1)

Where:

PR = Crude price in $/Bbl

A1 = API gravity coefficient determined through linear regression in $ by grade API-Bbl

APIR = Independent variable of API gravity

B = Sulfur coefficient determined through linear regression in $/%S-Bbl (negative number)

SR = Independent variable of sulfur content

b = Y interception determined from the linear regression in $/Bbl.

3.4.3

ADJSUTMENT OF VOLUMES FOR SENDERS (TABLE VI)

After obtaining the API and sulfur coefficients, a volumetric adjustment shall be calculated to conciliate differences between the quality of each Sender and the mix transported. The quantity to be adjusted for each Sender is determined as is follows:

Operation and Transport Regulations

Version 1

The relative value of Crude Oil for each Sender shall be calculated at the Point of Entrance. To obtain this, the API gravity of Crude from each Sender is multiplied by the API coefficient obtained in the regression and then adding to this result, the multiplication of the sulfur percentage of Crude from each Sender by the sulfur coefficient obtained in the regression. See table VI in the column – Relative value of Crude $/BBL

The relative value of the mix transported is calculated with the data of the relative value of each Crude Oil from all Senders. This value is obtained calculating the weighted average of the relative values of each Crude Oil multiplied by the volume delivered by the Sender. (See (1) table VI

After this, the average export price of the mix must be obtained with the data from exports of all Senders in the month in which the adjustments are made. (See (2) in table VI

To obtain the calculated price, the difference between the relative value of each Crude Oil and the relative value calculated for mix (1) must be obtained, and add this difference to the average export price of the mix.

Then, the quantity delivered by the Sender is multiplied by its calculated price and this product is divided between the average export price of the mix, obtaining as a result the total adjusted volume by Sender.

The volume to be adjusted shall be the difference between the total adjusted volume by Sender and the volume delivered by a Sender to the Pipeline.

The sum of volumes to be adjusted from all Senders must be cero.

The Transporter shall run the linear regression using a spreadsheet such as Excel. The Transporter shall document the statistical results of the linear regression so that the information can be provided to any Sender upon request.
