STATE AND CONTRACTOR CONSIDERATIONS

Contract No. CNH-R01-L01-A7/2015

PROCEDURES TO DETERMINE

STATE AND CONTRACTOR CONSIDERATIONS

This Annex establishes the terms and conditions under which the calculations and payment of the applicable Considerations under this Contract shall be carried out for any Month during the full term of this Contract, under the provisions of the Hydrocarbons Revenue Law prevailing at the time of the awarding of this Contract.

1.	Contractual Price

1.1	The Contractual Price for each type of Hydrocarbon will be determined based on the provisions of the Hydrocarbon Revenues Law, in accordance with the procedure established in this Annex 3.

1.2	Each Period, the Considerations indicated in Articles 16.2 paragraphs (b) and (c), and 16.3 paragraphs (a) and (b), will be calculated based on the Contractual Price of each type of Hydrocarbon, that shall be determined based on the criteria established in this Annex 3.

1.3	For purposes of this Annex 3, t shall mean the sub index corresponding to the Period. In case the Petroleum Activities are conducted during a Period which does not encompass a complete Month, the Period shall be the number of Days during which this Contract was actually in effect.

1.4	The Contractual Price of Crude Oil per Barrel will be determined as follows:

(a)

In case that during the Period the Contractor markets under Market Rules at least fifty percent (50%) of the Crude Oil volume delivered to it during the Period or there is a commitment for such marketing (including long term sale contracts under which the price is determined by Market Rules), the Contractual Price of Crude Oil for the Period in which the marketing is registered shall be equal to the average observed sale price weighted by the corresponding volume, that the Contractor has marketed or committed to market.

In the case of any volume that the Contractor sells or delivers to an Affiliate or a related party, which is in turn marketed to a third party without any intermediate treatment or processing, the sales price and volume corresponding to such Affiliate or related party transaction with a third party, may be considered in the calculation of the Contractual Price of Crude Oil during the Period.

(b)

In case that, during the Period, the Contractor does not market under Market Rules at least fifty per cent (50%) of the Crude Oil volume delivered to it in the Period, but the Marketer has registered marketing of the Crude Oil corresponding to the Contract Area based on Market Rules, the Contractual Price of Crude Oil shall be equal to the average price, weighted by the corresponding volume, reported by the Marketer.

Contract No. CNH-R01-L01-A7/2015

(c)

If at the end of the corresponding Period the Contractor has not registered marketing under Market Rules, of at least fifty percent (50%) of the Crude Oil volume delivered to him during the Period, or by the Marketer, the Contractual Price of Crude Oil shall be calculated based on the corresponding formula as a function of the API grade and sulfur content corresponding to the Crude Oil extracted within the Contract Area during the Period. The foregoing considering the prices for Light Louisiana Sweet (LLS) and Xxxxx xxxxxx crudes, published during the Period by an international company specialized in the publishing of reference information on prices, according to the following:

If the Contractor marketed less than fifty percent (50%) of the Crude Oil volume delivered to it during the Period, or if marketing was carried out by the Contractor or the Marketer with Related Parties, the Contractual Price of the Crude Oil will be the average of the prices calculated using the corresponding formula at the date of each marketing transaction, using the marker prices for such date, weighted by the volume involved in each transaction carried out during the Period.

ii.

If there was no marketing because the volume of Crude Oil produced in the period and registered at the Measurement Point was kept in storage under the ownership of the Contractor or the Marketer, the Contractual Price of Crude Oil will be calculated using the corresponding formula, considering the simple average of the marker prices during the Period.

The referenced formulas to calculate the Contractual Price of the Crude Oil are:

Where:


PC_P,t	=	Contractual Price of Crude Oil in Period t.

API	=	Adjustment parameter for quality, using weighted average API Grade of Crude Oil produced in the Contract Area.

Contract Area 7

[illegible signatures]

Contract No. CNH-R01-L01-A7/2015


LLS _t	=	Average market price of Louisiana Light Sweet Crude (LLS) in Period x.

Xxxxx _t	=	Average market price of Xxxxx Crude [ICE] in Period t.

S	=	Adjustment parameter for quality, using the value of the weighted average sulfur content of the Crude Oil produced in the Contract Area, Area using two decimal points (for example, 3.00 will be used for 3%).

The formulas to calculate the Contractual Price may be updated in this Contract to reflect the structural adjustments in the Hydrocarbons market, based on the information that the Ministry of Finance publishes in the annual report referenced in article 5 of the Hydrocarbon Revenues Law.

In case that prices for LLS and Xxxxx xxxxxx crudes are no longer published, the Ministry of Finance shall establish a new formula taking into account other marker crudes that have trading liquidity and reflect market conditions.

In case a Crude Oil in the market has the same quality characteristics (same API grade and sulfur content) than that of the Crude Oil produced in the Contract Area during the corresponding Period, the Contractual Price of Crude Oil used according to this subparagraph (c), may be calculated considering the referenced market price that is Free On Board (FOB), instead of estimated value using the corresponding formula.

Regarding the previous paragraph, the Contractor must present the documents with the verifiable information, published during the Period by an international company specialized in publishing reference information on prices, which proves that the proposed Crude Oil has the same API grade and sulfur content than that of the Crude Oil produced in the Contract Area, according to the measurements carried out by CNH during the Period.

(d)

In case that the Contractual Price of Crude Oil in the immediately preceding Period or in the two immediately preceding Periods was determined using the formulas established in subparagraph (c) of this subsection, and that during the Period there is marketing of Crude Oil under Market Rules by the Contractor or the Marketer in accordance with subparagraphs (a) and (b) of this subsection, the Contractual Price of Crude Oil in the Period will be determined using the following formula, as long as the difference between the estimated price based on the formula and the observed price during the marketing of Crude Oil based on Market Rules during Period t is less than or equal to fifty per cent (50%) of the observed price:

In case that the difference between the price estimated by the formula and the observed price during the Crude Oil marketing based on Market Rules during Period t is greater than fifty percent (50%) of the observed price, the Contractual Price of Crude Oil shall be determined as follows:

If the price estimated by the formula is greater than the observed price, the Contractual Price shall be:

ii.

If the price estimated by the formula is less than the observed price, the Contractual Price shall be:

Any variation in the Contractual Value of Crude Oil produced during the preceding Period or the two immediately preceding Periods, which persists considering the determination of the Contractual Price in accordance with this subparagraph (d) and the price observed under Market Rules, may be settled within the three (3) following Periods through the adjustments determined by the Ministry of Finance, as part of its verifications functions, in accordance with subsection 8.4 of this Annex 3.

(e)

In order for the price resulting from the marketing carried out by the Contractor to be considered in the determination of the Contractual Price of Crude Oil, the Contractor must have indicated prior to the closing of the Period the relevant characteristics of the marketing carried out, including the aspects to determine the applicable price under Market Rules. Notwithstanding the foregoing, the Contractor shall report the total revenues, the volume of Crude Oil and the average weighted price it obtains, derived from the marketing of the Crude Oil allocated to it as Considerations.

In case that during the Period the Contractor markets under Market Rules at least fifty percent (50%) of the volume of Condensates delivered to it during the Period based on Market Rules or there is a commitment for such marketing, including long term sale contracts under which the price is determined by Market Rules, the Contractual Price of Condensates during the Period in which the marketing is reported shall be equal to the average observed sale price weighted by the corresponding volume in each case, that the Contractor has marketed or committed to market.

In the case of any volume that the Contractor sells or delivers to an Affiliate or a related party, which is in turn marketed to a third party without any intermediate treatment or processing, the sale price and volume corresponding to such Affiliate or related party transaction with a third party may be considered in the calculation of the Contractual Price of Condensates in the Period.

(b)

In case that during the Period the Contractor does not market under Market Rules at least fifty per cent (50%) of the Condensates volume delivered to it during the Period, but the Marketer has registered marketing of the Condensates corresponding to the Contract Area based on Market Rules, the Contractual Price of Condensates during the Period shall be equal to the average price weighted by the corresponding volume, reported by the Marketer.

(c)

If at the end of the Period neither the Contractor or the Marketer have registered marketing under Market Rules of at least fifty percent (50%) of the volume of Condensates delivered to the Contractor, during the Period, the Contractual Price shall be calculated considering the average price for Xxxxx xxxxxx crude published during Period t by an international company specialized in the publishing of reference information on prices, according to the following:

If the Contractor marketed less than fifty percent (50%) of the volume of Condensates delivered to it in the Period, and the Marketer performed no transaction, or if marketing was carried out by the Contractor or Marketer with related parties, the Contractual Price of the Condensates will be the average of the prices calculated using the formula at the date of each marketing transaction, using the crude marker price at such date, weighted by the volume involved in each transaction carried out during the Period.

ii.

If there was no marketing because the volume of Condensates produced during the Period and registered at the Measurement Point was kept in storage under the ownership of the Contractor or the Marketer, the Contractual Price of the Condensates will be calculated using the corresponding formula, considering the simple average of the marker price during the Period.

Section IX. Fixed Assets.

1.22	When the Operator intends to transfer property as to which the Cost has been partially or completely recovered, it must obtain a technical opinion from CNH to justify that the asset to be transferred is no longer indispensable for the purpose of the Contract.

To determine the value of the asset transferred, the remaining book value or scrap value of the asset will be considered, provided that it is not less than the Market Price in accordance with subsections 1.20 and 1.21 of this Annex.

As a result of the verification work by the Ministry of Finance, and if it is not demonstrated that the sale was conducted at Market Prices, the difference identified between the median of the range of Market Prices and the agreed upon sale price, in accordance with the interquartile method procedure pursuant to the Applicable Laws, shall be delivered to the Fund or deducted from the Considerations that correspond to the Contractor.

With respect to the restitution of partially or totally damaged goods, the corresponding insurance compensation shall be deducted from the Recoverable Costs.

1.23

When the Cost of the asset transferred has been recovered in its entirety, subsection 1.22 of this Annex 4 must be complied with and the amount derived from the sale must be delivered to the Fund no later than ten (10) Business Days after the settlement of the sale or, subject to authorization from the Ministry of Finance, an equivalent amount will be deducted from the Consideration corresponding to the Contractor.

1.24	In the event that the Cost of the asset assigned has been partially recovered, the amount generated by such transaction will be distributed according to the percentage actually recovered at the time of the sale as between the State and the Contractor as provided in the Contract.

1.25	The Contractor, through the Operator may request authorization from the Ministry of Finance that the Considerations that correspond to it be discounted by an amount equal to the value of the transfer determined in accordance with subsection 1.22 of this Xxxxx 0,

attaching to its request the technical opinion provided by CNH, as well as the accounting record and support related to the transferred asset. The Ministry of Finance will have a period of five (5) Business Days to grant the referenced authorization by informing the Operator and the Fund of the authorization or denial.

1.26

The Operator shall notify the Ministry of Finance when it rents, leases or provides services with assets recorded as Recoverable Costs, and, as applicable, recovered under the Contract. The Fund will deduct from the Recoverable Costs the revenues which the Operator receives as a result of the rental or lease of goods. In case of the revenues that the Contractor receives for the provision of services in accordance with Annex 13, along with other costs associated with such services, they will be treated as indicated in subsection 1.16 and in Annex 13.

1.27

For the acquisition of goods whose Costs have been partially or completely recovered under another Contract, subject to approval by CNH, the book value, remaining or scrap value of the asset shall be considered, provided that it does not exceed the Market Price, adjusted to its useful life. In the event that the price of such assets exceeds the Market Price, the difference between the agreed upon price and the median range of Market Price, in accordance with the interquartile method procedure pursuant to the applicable tax laws, will not be considered a Recoverable Cost.

Section X. Inventories.

Contract No. CNH-R01-L01-A7/2015

1.4.

The goods or services that are linked to joint processes shall be agreed upon on an integrated basis, provided that this represents a greater guarantee on supply and greater economic benefit.

The guidelines or bidding requirements for the terms of reference for contests or biding processes shall establish legal conditions, and conditions of economic, financial and technical capability and of experience and other conditions that the contestants or bidders shall satisfy to participate. The Operator shall not establish requirements that prevent and hamper the participation of companies or violate the equality of applicants.

1.5.

In any event, the contest or bidding processes shall be carried out under principles of transparency, maximum publicity, equality, competitiveness and simplicity. The Operator may provide different awarding mechanisms. In the contest or bidding processes, tiebreaker criteria shall be stipulated, which shall be included in the corresponding contest or bidding guidelines.

The Operator shall observe the following:

For contracts or acquisitions valued less than or equal to US$1,000,000 (one million Dollars) or the equivalent in national currency, the Operator shall be free to determine the procedures and methods to choose the supplier it considers appropriate. The Operator shall retain the information, documentation, and/or evidence to demonstrate, for purposes of transactions related to such subcontracting or acquisition entered into with related parties, both residents in national territory and abroad, that they were determined considering the prices and amounts of consideration that would have been used with or between independent parties in comparable transactions.

The Contractor shall also clearly identify the subject matter of the contest or bidding process, the conditions of the service or delivery of the goods and/or services in order to determine the terms of the future contract. To the extent that goods and/or services are the subject matter of a contest or bidding process, unnecessary restrictions that reduce the number of qualified contestants or bidders should be avoided.

The method for the contest or bidding process shall preferably be one in which offers be submitted in writing, in sealed envelopes within the established time limits, signed by the legal representatives of the bidders, and complying with the requirements indicated in the contest or bidding documents.

The Operator shall not unnecessarily divide the acquisition and contracting processes in order to avoid the thresholds indicated in this subsection.

The thresholds referred to in this subsection shall be updated in the month of January based on the changes in the United States Producer Price Index, as published by the Bureau of Labor Statistics of the United States of America, with identification number WPU00000000, without seasonal adjustment, which represents an index of all merchandise or, if applicable, its substitute index by decision of the issuing institution.

In the event that, in any contracting conducted under the procedures referred to in sections II and III of the preceding subsection, the Costs increase due to unforeseen circumstances, the Contractor shall observe the following:

If the Costs increase by an amount equal to or lower than 5% (five percent), but are not higher than the benchmarks or market prices, in accordance with the analysis previously performed, it will not be necessary to justify such increase;

II.

If the Costs increase by an amount greater than 5% (five percent), but are not higher than the benchmarks or market prices, in accordance with the analysis previously performed, it will be necessary to justify such increase, and

III.

If the increase in Costs is higher than the benchmarks or market prices, the portion of the Costs beyond the range shall not be considered as Recoverable Costs.

1.7

The Operator may directly allocate the contract or acquisition to a related party or a third party, without the need for a contest or bidding process, so long as it is first demonstrated that the bid submitted by the related party or third party offers a price or consideration that is not higher than the benchmarks or market prices, amounts of consideration or profit margins found in reasonable markets, in accordance with the interquartile method procedure under the Applicable Laws and, if applicable, the benefits arising from such contracts are reflected in lower Costs to recover.

If under an accounting and financial verification it is identified that the value of the price is higher than the market benchmark or price, the difference will not be considered as a Recoverable Cost.

In the case of contracting goods and/or services with prices regulated by the State and no other purchase option exists, the Contractor may carry out make such contracts without a contest or bidding process and without conducting preceding studies.

If, instead of choosing to conduct any contracting under procedures II and III of subsection 1.5, the Operator directly allocates the procurement of goods and/or services to a related party or third party, the criteria in subsection 1.6 of this Annex will apply if there are increases in Costs.

Any analysis or study with the purpose of showing that an acquisition or contract is at reference values for transactions with third parties or at market prices for related parties must be accompanied by all information to permit replication of the results obtained, as well as the criteria followed in its preparation. If the information that the Operator provides is insufficient for the Ministry of Finance to replicate the results, the difference above the median value of the relevant Cost, in accordance with the interquartile method procedure under the Applicable Laws, shall not be considered as Recoverable Cost.
