CONTRACT No. 424048860

THREE

METHOD OF PAYMENT. The CONTRACTOR will receive from PEP the amount resulting from applying the unit prices to the amounts of work performed, as total payment for each item unit of work completed, executed according to the contract, construction specifications and quality standards.

The amount to pay for the work hereunder will be calculated by preparing estimates that will cover monthly periods and will be submitted by the CONTRACTOR to the site supervision office. They will be accompanied by the documentation that certifies the admissibility of their payment, within 6 (six) calendar days following the cut-off date, which will be the last day of each month. If the estimates are not submitted in the aforementioned term, the corresponding estimate will be submitted on the following cut-off date, without giving rise to a claim for expenses and/or financing costs from the CONTRACTOR. The site supervision office will have a period no longer than 15 (fifteen) calendar days to review and authorize the estimates, following the date that the corresponding estimates are submitted to it.

When analyzing and calculating the payment amounts, the applicable fees and taxes shall be considered, under the terms of the tax laws. The CONTRACTOR will be solely responsible for the invoices meeting the administrative and tax requirements for their payment. Therefore, the delay in their payment due to the lack of any of these, or due to their incorrect or late submission, will not be grounds to request the payment of financing expenses as referred to in article 55 of the Law of Public Works and Related Services.

The parties who sign this contract in their capacity as CONTRACTORS, agree that the company MERCO INGENIERIA S.A. DE C.V., in its capacity as Common Representative, will be the one to submit the invoices for each and every one of the payments arising from this contract. This is with the understanding that PEP will not be liable for the manner in which the Common Representative distributes or divides the earnings or losses with respect to the amounts that it receives as a result of this contract.

The submission date of the estimates to the site supervision office shall be recorded in the log.

Estimates for work performed shall be paid by PEP, under its responsibility, within a period no longer than 20 (twenty) calendar days, from the date on which they have been authorized by the site supervision office. This date will be recorded in the log of the work and in the estimates themselves.

Payments to the CONTRACTOR will be done invariably by an automatic bank deposit into account of the credit institution authorized to operate in the United Mexican States, selected by the CONTRACTOR, who shall notify PEP in writing directly at the Payment Window for the North Region, located at Boulevard campo PEMEX s/n (to one side of the vehicle entrance #2) interior campo PEMEX Col. Herradura X.X. 00000, Xxxx Xxxx de Hgo. Ver, prior to the first of the payments that take place under this contract.

The estimates and the settlement, even though they have been paid, will not be considered full acceptance of the work, since PEP expressly reserves the right to file claims for missing or poorly performed work, and where appropriate, for the excess payment that has been made.

The payment of the cost adjustments and financing cost will be done in the estimates following the month on which the granted adjustment has been authorized, by applying to the amount of the aforementioned estimates the detailed increase corresponding to said factors for each type of adjustment. The latest adjustments that have been authorized shall be applied. All adjustment factors granted shall accumulate.

Payment of the authorized estimates of non-recoverable expenses that are duly proven will be done in accordance with the terms and conditions of the second paragraph of article 54 of the Law of Public Works and Related Services. No additional cost will be applicable to the resulting amounts, whether for indirect costs, financing or profits.

FINANCING SOURCES. The CONTRACTOR acknowledges that Petróleos Mexicanos, its Subsidiary Agencies or any financial institution and/or affiliate that it may designate for this purpose, may use the resources from financing, in order to finance the payments arising from this contract.

The “Country of Origin Certificate for Goods and/or Services”, submitted prior to the signing of this contract, is integrated into this contract as attachment “G-1”, with the understanding that PEP may request any clarification or additional information from the CONTRACTOR regarding the certificate referred to in this clause during the validity of the contract. Likewise, in the event that the information considered in said certificate were to be amended during the validity of this contract, the CONTRACTOR undertakes to notify PEP immediately after the CONTRACTOR is aware of the amendment, which will not mean that an amendment is made to this contract.

The CONTRACTOR undertakes to submit the documentation required by the financing sources, which shall be submitted in accordance with the requirements established in attachment “G” named “Documentation Required by Financing Sources”. To this end, it will follow the instructions and specific formats in force that are contained within the “Instructions from Petróleos Mexicanos and its Subsidiary Agencies for the Submission of Documentation Required by the Financing Sources”, which was delivered to it prior to the signing of this contract. The current instructions referred to in this clause, are also available on the following webpage of PEMEX: xxx.xxxxx.xxx/xxxxxxxxxxx/xxxxxxxxxxxxx.

The CONTRACTOR shall appear at the responsible department (“Financing Module”) of PEP, before each payment event in order to provide the documentation required by the financing sources, which may apply.

CONTRACT No. 424048860


FIVE		ASSIGNMENT OF COLLECTION RIGHTS. The CONTRACTOR may not assign the rights and obligations arising from this contract either partially or fully in favour of any other individual or legal entity, except for the collection rights on the estimates for the work performed. In this case, the CONTRACTOR shall request consent from PEP in writing, who will come to an appropriate decision within a term of 15 (fifteen) calendar days from the request submission. In the event that the aforementioned period has passed without PEP having given a response in writing to the request from the CONTRACTOR, this request will be considered not accepted. If as a result of the assignment of the collection rights requested by the CONTRACTOR, a delay in payment were to occur, the payment of financing expenses as referred to in article 55 of the Law of Public Works and Related Services will not apply. Neither will the process of assigning collection rights grant the CONTRACTOR the right to request an extension to the completion date.
SIX		WITHHOLDINGS. The CONTRACTOR accepts that the following withholdings will be performed on each of the estimates that are paid:
		a).- FIVE THOUSANDTHS of the amount of the work performed, which will be set aside for the Ministry of the Civil Service for the fees from the inspection service, supervision and control of the work, which PEP will deliver to the Treasury of the Federation, in accordance with article 191 of the Federal Law of Fees.
SEVEN		FINANCING EXPENSES. In the case of non-compliance in the payment of the estimates and cost adjustment, PEP at the request of the CONTRACTOR, shall pay financing expenses at a rate that will be equal to that set by the Revenue Law of the Federation in cases of late payment of tax credits. Said expenses will begin to be generated when the parties have defined the amount to be paid and will be calculated on the unpaid amounts. They must be calculated by calendar days from the time they are calculated and until the date they are actually made available to the CONTRACTOR, in accordance with article 55 of the Law of Public Works and Related Services.
EIGHT		EXCESS PAYMENTS. In the case of excess payments that the CONTRACTOR has received, it shall return the excess amounts paid plus the corresponding interest, as indicated in clause six “WITHHOLDINGS” of this contract. The interest will be calculated on the excess amounts paid in each case and will be calculated by calendar days, from the payment date to the date on which the amounts are actually made available to PEP. It will not be considered an excess payment when the differences borne by the CONTRACTOR are offset in the following estimate, or in the settlement, if said payment had not been identified previously.
NINE		COST ADJUSTMENT. The parties agree to the review and adjustment of the costs that make up the unit prices of this contract, agreed upon in local currency, in accordance with article 56 of the Law of Public Works and Related Services and articles 105, 106 and 144 of its Regulations. Therefore, both parties agree to take the itemized costs that are listed in Format DE-1 as the basis for performing the costs adjustments, which the CONTRACTOR attached in its proposal. According to article 105 from the Regulations of the Law of Public Works and Related Services, within 60 (sixty) calendar days following the publication of the indices that are applicable to the period for said indices, the CONTRACTOR shall request the corresponding cost adjustment from PEP. Once the above period has passed, the CONTRACTOR no longer has the right to claim the cost adjustment for the period in question. Within 60 (sixty) calendar days following receipt of the request, PEP will issue the applicable decision in writing.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860

Adjustment of the costs that make up the agreed unit prices in local currency, which are part of the total direct costs, will be done according to the express terms of articles 56, 57 section III and 58 of the Law of Public Works and Related Services, and articles 145, 146, 147, 152 and 153 of its Regulations.

LOCAL CURRENCY.

I. The adjustments will be calculated from the date on which the increase or decrease has occurred in the cost of the inputs, with regard to the incomplete work, according to the execution schedule agreed upon in the Contract, or if there is a delay not attributable to the CONTRACTOR, regarding the schedule that had been agreed upon.

When the delay is due to causes attributable to the CONTRACTOR, the cost adjustment will proceed exclusively for the incomplete work according to the schedule that had been agreed upon.

The base indices that will serve for calculating the cost adjustments in the Contract will be those that correspond to the date of the ceremony for submission and opening of proposals.

The original prices of the inputs shall be the prevailing prices at the time the proposals are submitted and opened, and may not be modified or replaced by any variation that may occur between the date they are submitted and the last day of the adjustment month.

II. The cost increases or decreases of the inputs will be calculated based upon the Producer Price Indices for Services that the Bank of Mexico publishes.

When the indices that the CONTRACTOR and PEP require are not found among those published by the Bank of Mexico, PEP will proceed to calculate them according to the prices that it investigates, using the guidelines and methodology issued by the Bank of Mexico.

In the specific case of labour, the variation corresponding to the minimum wage of the corresponding Region will be used as the index, which is published by the National Minimum Wage Commission in the Official Journal of the Federation.

III. The original prices of the Contract will remain fixed until the completion of the contracted work. The adjustment will be applied exclusively to the direct costs, holding the indirect costs and original earnings constant during the performance of the Contract. The financing cost will be subject to variations in the interest rate that the CONTRACTOR has considered in it its proposal; and

IV. All other guidelines that the Ministry of the Civil Service may issue in this regard.

Review of the cost adjustments will be monthly, where the parties agree that the authorized factors will remain fixed during this period. For calculation of the factor that will prevail during the monthly period, the indices corresponding to the calendar month are considered, for the month in which the validity of the factor begins.

Calculation of the cost adjustments will be subject to the provisions of Section II of CHAPTER FIVE from the Regulations of the Law of Public Works and Related Services.

When the cost adjustment moves upwards, the CONTRACTOR will be the one to initiate it. If it is downwards, PEP will be the one to do this.

Within sixty (60) calendar days following the receipt of the request, PEP will issue the applicable decision in writing. The authorization of the cost adjustment shall be made through the official decision document that agrees to the corresponding increase or decrease.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860

The payment of the cost adjustments will be made on the estimates following the month in which the granted adjustment has been authorized.

The procedure used for updating prices consists of calculating the sum of the terms formed by each of the proportions or incidents (expressed in decimals) in which the respective inputs take part, multiplied by the quotient formed by the relative current and prior inputs corresponding to the dates that determine the update period. The cost adjustment procedure in local currency may not be modified during the contract term.

The above procedure can be expressed in the following equation:

LOGO


				Where:

				Pa =		Updated sum price.
				Po =		Contractual sum price that is to be updated.
				S =		Sum of the “n” terms.
				Zm =		Proportion or incident in which the input “m” takes part in the direct cost of the work.
				INm =		Is the relative cost input on the update for the input “m”
				IOm =		Is the relative cost input on the proposal submission and opening date.
				m =		Number of inputs that can go from 1 to “n”.
				Ffm =		Modified Financing Factor.
				Fo =		Original Financing Factor as a fraction.
				Ia =		Updated Interest Rate as a fraction.
				Io =		Original Interest Rate as a fraction.

DOLLARS:

The adjustment of the costs that make up the agreed unit prices in dollars, which take part in the total direct cost, will be done according to the express terms of article 33 section VI of the Law of Public Works and Related Services and article 153A of its Regulations.

Review of the costs for the portion offered in Dollars shall be done through the following procedure:

I. The adjustments will be calculated from the date on which the increase or decrease to the established index has taken place, with respect to the incomplete work, according to the execution schedule that had been agreed upon in the Contract, or in the event that there is a delay not attributable to the CONTRACTOR, with respect to the schedule that had been agreed upon.

When the delay is due to causes attributable to the CONTRACTOR, the cost adjustment will proceed exclusively for the incomplete work, according to the schedule that had been agreed upon.

The date that will serve as a basis for calculating the cost adjustments for the dollar portion, will be the date corresponding to the proposal submission and opening ceremony.

Review of the cost adjustments will be monthly

II. The increase or decrease in costs of inputs will be calculated for inputs other than foreign labour upon the basis of the Producer Price Index PCUOMFG-OMFG, while foreign labour will be based upon the Average Weekly Earnings of Production Workers CES0500000030, both published by the Bureau of Labor Statistics of the US Department of Labor. For national inputs other than labour, they will be based upon the Producer Price Index with Services excluding petroleum SP6, and for labour, the minimum wage published by the National Minimum Wage Commission in the Official Journal of the Federation of the corresponding region, as well as the average monthly exchange rates for meeting obligations in foreign currency published by the Bank of Mexico.

III. The original prices of the Contract will remain fixed until the completion of the contracted work. The adjustment will apply exclusively to the direct costs offered in dollars, with the excess cost factor remaining constant, and

IV. To all other guidelines that the Ministry of the Civil Service issues for this purpose.

When the cost adjustment moves upwards, the CONTRACTOR will be the one to initiate it. If it is downwards, PEP will be the one to do this.

The payment of the cost adjustments will be made on the estimates following the month on which the granted adjustment has been authorized.

The formalization of the cost adjustment shall be done through the official decision letter that agrees upon the corresponding increase or decrease. Consequently, no agreement will be required.

		The penalties will be applied on the estimates that the CONTRACTOR generates. If it is not possible to apply the established penalties in any of the above cases, the CONTRACTOR is under obligation to deliver to PEP the amount corresponding to said penalties through a certified cheque, otherwise the performance bond will be exercised.

The contractual penalties established in this clause may in no case be greater than the amount of the performance bond in their entirety. The application of said penalties will not take place when the delay or interruption comes from an act of God or force majeure event or any other cause not attributable to the CONTRACTOR. The penalties for delay in the performance of the work agreed to in this clause, or any other contractual penalty that must be applied in relation to this contract, will be applied against the estimates that the CONTRACTOR submits to PEP and that PEP pays to the company MERCO INGENIERIA INDUSTRIAL S.A. DE C.V., by virtue of its appointment as Common Representative, regardless of which of the parties is responsible for the delay in the performance of the work and/or any other breach of contract, according to the parts of the works that each company is under obligation to perform as referred to in clause one of this contract, with the understanding that PEP will not be responsible for the manner in which the Common Representative applies the penalties and/or distributes the payments that it receives as a result of this contract.

ELEVEN		PERFORMANCE PERIOD. The CONTRACTOR undertakes to perform the work hereunder in *730* calendar days from September 26, 2008 and to complete it no later than September 25, 2010, in accordance with the stipulations agreed to in the contract and its attachments.

TWELVE		TERM. This contract will be valid from the date of its signing and until the legal act is formalized through which the rights and obligations of the parties are ended in their entirety.

THIRTEEN		EXTENSION TO THE COMPLETION DATE. The completion date indicated in the clause named “PERFORMANCE PERIOD”, may be extended, without the performance period of the contract being modified in this regard, by adjusting the execution schedule, only when the following events occur: (a) If any duly proven act of God or force majeure event occurs, the completion date of the performance period will be extended by a period of time equal to that of the suspension caused by the same, provided an annotation is made in the log and the CONTRACTOR submits its extension request in writing to PEP along with the corresponding support documentation, which shall be done prior to the notice of completion of the work. If said request is not submitted by the CONTRACTOR and said annotation is not performed, no extension will be granted.

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		said request is not submitted by the CONTRACTOR and said annotation is not performed, no extension will be granted. In the event that it is proven that the event is attributable to PEP, it shall give its decision regarding the extension request within 30 (thirty) calendar days following the submission of the request. If it does not do so, the request will be considered accepted. In the event the extension is accepted, this shall be formalized through the corresponding support certificate; and (c) In the event that PEP orders the suspension of work, it shall proceed in accordance with the clause named “CONTRACT SUSPENSION”.

FOURTEEN		WORK FOR ADDITIONAL AMOUNTS OR FOR ITEMS NOT ESTABLISHED IN THE ITEM CATALOGUE. If during the contract period, PEP requires the performance of additional amounts of work or work for items not established in the item catalogue, or the CONTRACTOR realizes the need to carry them out, the latter may only perform said work once it has written authorization or through an annotation on the log by the site supervisor, except in cases of an emergency where it is not possible to wait for his authorization. In the event that the scenarios established in this clause were to occur, the CONTRACTOR, once the work is performed, may prepare its estimates and submit them to the site supervisor on the following estimate. PEP may authorize the payment of the estimates for the work performed. In the case of additional amounts, these will be paid at the unit prices originally agreed to in this contract. In the case of items not established in the item catalogue, their unit prices shall be reconciled and authorized prior to their payment, pursuant to the provisions of articles 76, 77, 78 and other applicable articles of the Regulations of the Law of Public Works and Related Services.

These events are unavoidable, unforeseeable, or cannot be avoided even when they are foreseen, which prevent the affected party from performing its obligations in accordance with this contract. Among others, the following events are considered to be acts of God or force majeure: strikes and labour disturbances (provided they have not given rise or contributed to them), riots, quarantines, epidemics, wars (declared or not), blockades, civil disturbances, insurrections, fires (when they have not given rise or contributed to them) and storms. In the event of suspension of work arising from an act of God or force majeure, the provisions of the clauses named “EXTENSION TO THE COMPLETION DATE” and “CONTRACT SUSPENSION” will be observed.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		The CONTRACTOR expressly states:

		(A)		Its intent to waive the right for compensation as granted by the applicable substantive legislation, in the event there are credits in its favour owed by PEP. It therefore gives its express consent so that the granted guarantee may take effect in the event of a breach of the obligations arising from this contract, as well as any other balance in favour of PEP.

		(B)		Its consent to the bond being paid independently of any type of appeal being filed to the administrative or non-judicial courts.

		(C)		Its consent for the bond that guarantees contract performance to remain in force during the substantiation of all judicial or arbitration proceedings and the respective appeals that are filed in relation to the contract, until the final decision is given that orders execution by the governing authority or court.

		(D)		Its consent to be bound jointly with its surety in the case of a claim, and based upon the power that it is granted by article 118 bis of the Federal Law of Surety Institutions, that the exception of judicial consideration will only be justified if a sealed copy of the lawsuit is produced. In this lawsuit it must state that by exercising the principal action, the debtor indicates this contract as being the document for the basis of this action, and that there is a relationship between the benefits claimed and the facts that support the non-admissibility of the claim. It expressly waives any other meaning that may be given to the exception of judicial consideration or enforceability of the bond policy that is subject to a judicial or administrative dispute between the parties of this contract. Likewise, in this scenario, the surety institution will enter the payment of the applicable amount on the business day immediately following the expiry of the thirty-day period granted by article 93 of the Federal Law of Surety Institutions to decide on the admissibility of the claim.

		(E)		Its acceptance of the performance bond staying in force until the guaranteed obligations have been fulfilled in their entirety to the satisfaction of PEP, with the understanding that the agreement for its release shall be granted through a document signed by PEP.

		(F)		Its consent to the surety settling 50% of the amount guaranteed in the bond to PEP in the event that it does not submit the warranty on defects, latent defects and any other liability under the terms of the provisions of the Law of Public Works and Related Services and of this contract.

		(G)		Its consent to the claim that is submitted to the surety due to breach of contract, being duly integrated with the following documentation: 1. Written claim to the surety institution. 2. Copy of the bond policy and its amending documents, where applicable. 3. Copy of the guaranteed contract and its attachments, where applicable. 4. Copy of the notification document to the debtor for its breach of contract. 5. Quantification of the breach of contract.

		(H)		Its consent to the surety paying the maximum guaranteed amount to PEP in the event that the work hereunder is not usable or available by PEP, notwithstanding the fact the corresponding progress certificate had been issued. This is with the understanding that any exception arising from the investment and/or partial or total application of the advance payment and/or payment of estimates will not be valid for the purpose of determining the enforceability of the entire amount guaranteed in the bond. This is because, according to the purpose of this contract, the obligation of investing and/or applying the advance payment and the payment of estimates is indivisible, since its purpose is a performance of work that can be useful or available to PEP only when it is fulfilled in its entirety. Consequently, any application of funds and/or partial or full investment of the advance payment and/or payment of estimates received by the CONTRACTOR that does not bring about useful and available work to PEP in accordance with the purpose of this contract, will be ineffective for establishing any exception that attempts to lessen the enforceability of the total guaranteed amount.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		(I)		Its consent to remove and take away the equipment or goods hereunder, in the event they are not useable or exploitable, when so required by PEP.

		In the event of any modification to the amount or period agreed to in this contract and/or its attachments, the CONTRACTOR undertakes to deliver to PEP within fifteen (15) calendar days following the formalization of the respective amending agreement, the amending document for the originally granted guarantee, according to the terms established in this contract, where the obligations of this contract and the corresponding agreement are guaranteed. In the event that the CONTRACTOR does not comply with this delivery, PEP may decide to enforce the administrative rescission of the contract. The amending document shall contain the stipulation that it is joint, several and inseparable from the bond initially submitted by the CONTRACTOR. Provided the contract is being complied with under the agreed terms, the guarantee shall be replaced by another equivalent to 10% (ten percent) of the amount of the work not yet performed, including amounts related to cost adjustments and agreements in said sum, if any, except for what is provided for in the second paragraph of article 61 of the Regulations of the Law of Public Works and Related Services, which will be submitted within 15 (fifteen) calendar days from the date on which the CONTRACTOR is notified in writing of the authorized investment. WARRANTY ON LATENT DEFECTS. Once the work is completed, or accepted (where applicable) under the terms of article 138 of the Regulations of the Law of Public Works and Related Services, the CONTRACTOR will be liable for the defects arising therefrom, from latent defects and any other liability that it has incurred, under the terms indicated in this contract and in the applicable legislation. The work will be guaranteed for a period of 12 (twelve) months for compliance with the obligations referred to in the above paragraph. Therefore, prior to accepting the work, the CONTRACTOR, at its own choosing, shall create a bond for the equivalent of 10% (ten percent) of the total exercised amount of the work; submit a standby letter of credit for the equivalent of 5% (five percent) of the total exercised amount of the work, or provide liquid funds for an amount equivalent to 5% (five percent) of the same amount in trusts especially created for this purpose. This warranty will be released once the twelve months have elapsed, starting from the date of the physical certificate of acceptance of the work, provided that no liability has arisen against the CONTRACTOR during that period. When the quality warranty is created through a bond policy, it shall be issued by an authorized surety institution, and shall be issued in strict adherence to the Format DI-4 presented in the bidding guidelines of this contract. When the quality warranty is created through a standby letter of credit, it shall be confirmed or issued by a banking institution authorized to operate in Mexico, and shall be issued in strict adherence to the quality warrantee format issued by the Risks and Insurance Management of this contract. When the warranty is created through the contribution of liquid funds in a trust, the latter shall be managed by a trust institution authorized to operate in the Mexican Republic. The Trust shall include the following aspects: it shall be irrevocable; shall be made out to PEP as the beneficiary; and the resources under the trust shall be invested in fixed income instruments. If the warranty on defects, latent defects in the work and any other liability was established through a bond, it will be released in accordance with the provisions of the bond policy that is granted under the terms of article 68 of the Regulations of the Law of Public Works and Related Services.

CONTRACT No. 424048860


		The CONTRACTOR, where applicable, may withdraw its contributions into the trust and the respective earnings, after twelve months have passed from the date of acceptance of the work. The bond or letter of credit will be automatically cancelled in the same period of time, as the case may be. In the event that an irrevocable letter of credit has been issued, the CONTRACTOR will proceed with its immediate cancellation. The rights of PEP will be preserved to demand the payment of amounts that are not paid from the compensation that in its opinion are applicable, once the guarantees are exercised according to this clause. If prior to the execution of the applicable guarantees, the CONTRACTOR states its desire to pay the guaranteed amount directly, said payment shall be received by PEP. In this case, the corresponding guarantees shall be released.

EIGHTEEN		INSURANCE POLICIES. The CONTRACTOR shall have insurance policies for Construction All Risks and/or Assembly during the physical execution of the works (including, where applicable, performance tests), issued by an insurance company legally authorized for this purpose by the United Mexican States. It will deliver to PEP, prior to the start date of the physical execution of the works, a copy and original of the documents that prove payment of the premiums for comparison and to be later returned. In the case of any accident that occurs during the term of the policy, the Contractor will be solely responsible for filing any claim to its insurers, completely documented. Any and all deductibles applicable to the aforementioned insurance policy will invariably be assumed by the Contractor. If the aforementioned insurance policies are not delivered to PEP the day prior to the start date of the physical execution of the works at the very latest, PEP will be authorized to not allow the Contractor to execute the works hereunder, and this will not release the Contractor from its full responsibility as far as the Execution Schedule originally agreed to for the performance of the contract purpose. In the case of any amendment to this contract that affects the insurance policies, the Contractor shall deliver the respective policy or endorsement prior to the formalization of the amendment. The Contractor will be solely responsible for taking out the insurance limits, terms, conditions and scope of the coverage, as well as the deductibles and exclusions, which it deems appropriate based upon its risk analyses. Therefore, PEP will not be responsible for the sufficiency or insufficiency of the insurance conditions that the insurance policy may have. OTHER INSURANCE The Contractor will be solely responsible for having any other insurance policy at its cost, which it deems necessary according to the nature and complexity of the contract scope.

NINETEEN		AUTHORIZED REPRESENTATIVES. PEP, prior to commencement of the work, will designate the site supervisor, who will perform the functions established in article 53 of the Law of Public Works and Related Services, and article 84 of its Regulations. Through this site supervisor, it will give the CONTRACTOR instructions in writing that it deems pertinent related to its performance, in the agreed manner and with the modifications that PEP may order. Supervision is the technical assistance provided by the site supervisor’s office, with the functions that are indicated in this regard under article 86 of the Regulations of the Law of Public Works and Related Services, independently of those that may be agreed to in the supervision contract, where applicable.

The construction superintendent of the CONTRACTOR, as referred to in this clause, may not act as a manager over industrial safety, occupational health and environmental protection of the CONTRACTOR. At any time and with sufficient grounds, PEP may request that any of the CONTRACTOR’S representatives be changed, and the latter is under obligation to designate another person who meets the corresponding requirements.

TWENTY		SUBCONTRACTING. In the event that the CONTRACTOR needs to subcontract any part of the work or when it purchases materials or equipment that include their installation on the site, which have not been included in its proposal as work to be subcontracted, it shall request authorization from PEP 05 (FIVE) calendar days in advance to the scheduled commencement of the work it intends to subcontract. It shall indicate: (i) the name of the possible subcontractor in question; (ii) the part of the work to be subcontracted; and (iii) sufficient information so that PEP is able to evaluate the technical capability of the possible subcontractor. Likewise, PEP will be entitled to request from the CONTRACTOR any information in addition to that delivered by the latter, in order to authorize the subcontracting in question. PEP will have a period of 05 (FIVE) calendar days from the date of receipt of the notification, or from the date of receipt of the additional information requested, to accept or reject the execution of said contract in writing. In the event that the aforementioned period has passed without PEP having accepted or rejected the request from the CONTRACTOR in writing, it will be deemed not accepted. In the event that the CONTRACTOR wishes to replace a subcontractor, it shall request authorization from PEP under the terms indicated in this clause. This will not be grounds for increasing the agreed prices or the execution period. The parties agree that the CONTRACTOR will be strictly prohibited from subcontracting the work hereunder in its entirety. Notwithstanding any subcontracting, the CONTRACTOR is and will be solely liable for the quality and the proper and timely execution of the work in accordance with this contract.

For this reason, the CONTRACTOR agrees to be liable for all claims that its workers or third parties may file against it or against PEP, including personnel from its authorized subcontractors who take part in the contracted work with or for PEP. In the event that PEP is involved, it will be under obligation to hold PEP harmless from any trial or liability arising from the performance of the work hereunder. It will likewise compensate PEP whenever the latter may so request in writing, for any amount that it should pay in this regard, including the payment of lawyers’ fees.

LIABILITY OF THE PARTIES. The CONTRACTOR will be solely liable for the performance of the work and will be subject to all laws, regulations and legislation of the governing authorities in the area of construction, safety, use of public roads, ecological and environmental protection that govern federal, state or municipal boundaries.

In this case, PEP, if it deems appropriate, may order the total or partial suspension of contracted work, as long as said additional work is not performed. This will not be grounds for increasing the amount or time period indicated in this contract for its completion.

If the CONTRACTOR performs work for a value higher than what has been contracted, independently of the liability that it incurs for performing excess work, will not be entitled to claim any payment whatsoever, nor any modification of the period for performing the work.

The acceptance of the work will be done in accordance with article 64 of the Law of Public Works and Related Services, and articles 135, 136, 137 and 138 of its Regulations. Acceptance of the work will be recorded in the corresponding certificate. Once the work hereunder has been concluded, the complete acceptance of said work will proceed. For the purposes of the foregoing, the CONTRACTOR will notify PEP in writing or through a record that is made on the log, of the full completion of the work, indicating that all of this work is completed in accordance with the terms of reference of this contract. Within fifteen (15) calendar days following the date of receipt of the aforementioned notification, the resident service supervisor will verify that the work is properly concluded, and must prepare the corresponding support certificate. If during verification of the work, the site supervisor’s office observes deficiencies in the performance and completion thereof, or decides that it has not been performed according to the contract terms of reference, it will request in writing that the CONTRACTOR repair or correct it, so that it may be performed pursuant to the provisions established in this contract. In this scenario, the agreed verification period of the work in the contract may be extended for the period of time agreed upon by the parties to correct the deficiencies. The foregoing is without prejudice to PEP deciding to rescind the contract. When defects or latent defects appear within the year following the completion date that is established in the acceptance certificate, in the work performed or goods provided for executing the purpose of this contract, PEP will request their immediate repair or replacement, which the CONTRACTOR will complete without any entitlement to compensation. If the CONTRACTOR should not attend to the requirements of PEP within the stipulated period, the latter may entrust the repair or replacement to third parties or do it directly, under the terms of the applicable legal provisions, at the expense of the CONTRACTOR.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		If the CONTRACTOR should not attend to the defects and latent defects in the work performed or goods provided for executing the purpose of this contract, at the order of PEP within the requested period, PEP will exercise the warranty granted by the CONTRACTOR, for the period of 12 (twelve) months once the work is concluded, as referred to in the corresponding paragraph of the clause named “CONTRACT PERFORMANCE BOND AND WARRANTY ON LATENT DEFECTS” of this contract.

TWENTY-FOUR		SETTLEMENT AND CONTRACT COMPLETION. Having physically accepted the work, PEP through the site supervision office, and the CONTRACTOR, shall prepare the settlement of the work within a term of 60 (sixty) calendar days, wherein credits in favour and against each of the parties will be recorded, describing the general item that gave rise to them and the resulting balance, under the terms of article 64 of the Law of Public Works and Related Services, and articles 139 to 143 of its Regulations. The document where the settlement of the work is recorded will form part of this document and shall at least contain the stipulations of article 141 of the Regulations of the Law of Public Works and Related Services.

TWENTY-FIVE		CONTRACT SUSPENSION. PEP has the power to suspend temporarily, in whole or in part, the work contracted in any state in which it is found, on justified grounds or of general interest, and may decide on the temporary nature of the suspension, which may not be extended or be indefinite, without this implying the termination of the contract. For this reason, PEP will notify the CONTRACTOR, stating the causes bringing this about, the date it will start and the probable resumption of work, as well as the actions that it must consider with regard to personnel and construction equipment. In all cases of suspension, the site supervisor’s office will prepare a support certificate that will contain at least what is indicated in article 117 of the Regulations of the Law of Public Works and Related Services. The completion date will be extended proportionately to the period that includes the suspension, without modifying the agreed performance period. The deficient supply of materials and permanent installation equipment by the CONTRACTOR will not be grounds for suspending the work, when said supply is the responsibility of the CONTRACTOR. When the suspension of work is decided due to causes attributable to PEP, the CONTRACTOR may request the payment of non-recoverable expenses from the time of notification that terminates the suspension, provided these are reasonable, duly proven and related directly to this contract, as stated in article 62 of the Law of Public Works and Related Services, and are generated during the suspension. These expenses will be limited to the provisions of article 116 of the Law of Public Works and Related Services. If during the validity of this contract there are suspensions of work, which periods are reduced and difficult to quantify, the parties may agree that the periods be grouped on a monthly basis and formalized by signing a single support certificate, which will be prepared on the first day of the month following the month on which these suspensions had taken place. When the suspensions arise from an act of God or force majeure, there will be no liability whatsoever to the parties. They must only sign an agreement where it acknowledges the period of the suspension and the dates for restarting and ending the work, without modifying the execution period established in the contract. Therefore, only the payment of non-recoverable expenses indicated in the second paragraph of article 119 of the Regulations of the Law of Public Works and Related Services will proceed. When the continuation of services is made impossible by the act of God or force majeure, the CONTRACTOR may choose to not carry them out. In this scenario, it shall observe the provisions of the clause named “EARLY TERMINATION OF THE CONTRACT” of this agreement in principle.

TWENTY-SIX		EARLY TERMINATION OF THE CONTRACT. PEP may terminate this contract early through a written notice given to the CONTRACTOR for this purpose, pursuant to the terms of articles 60 and 62 of the Law of Public Works and Related Services and articles 120, 121, 122 and 123 of its Regulations.

TWENTY-SEVEN	ADMINISTRATIVE RESCISSION OF THE CONTRACT. PEP may rescind this contract administratively, in the event that the CONTRACTOR breaches its obligations in the following cases:

	1).-	If the CONTRACTOR, due to causes attributable to it, does not commence the work hereunder within fifteen calendar days following the agreed date without just cause, pursuant to the Law of Public Works and Related Services and its Regulations.

	4).-	If the CONTRACTOR does not comply with the work orders due to a lack of materials, labour or construction equipment, and in the judgment of PEP it may hinder the satisfactory completion of the work within the stipulated period or stage. This will not mean a delay in the performance of the work order, and will therefore not be considered a breach of this contract and grounds for its rescission, when the delay takes place due to the lack of information with regard to plans, specifications and quality standards, physically turning over the work areas and the timely delivery of materials and permanent installation equipment, licenses, permits that PEP must provide or furnish, as well as when PEP had ordered the suspension of the work.

	5).-	If the CONTRACTOR is declared to be under bankruptcy proceedings under the terms of the Bankruptcy Proceedings Law.

	6).-	If the CONTRACTOR subcontracts part of the work hereunder, without having the written authorization of PEP.

	7).-	If the CONTRACTOR assigns the collection rights arising from this contract, without the written authorization of PEP.

	8).-	If the CONTRACTOR does not provide the necessary means and information to PEP and the departments that have the power to intervene for the inspection, oversight and supervision of the services.

	9).-	If the CONTRACTOR fails to keep the guarantees current during the execution time of the work, or in the event that other guarantees are required due to the amendments to the contract (endorsements), these guarantees are not delivered, or when delivered they do not meet the conditions stipulated in the contract and the applicable standards.

	10).-	The disclosure of confidential information to third parties that PEP has provided to the CONTRACTOR.

	11).-	The violation of professional secrecy or disclosure of confidential information to third parties that PEP has provided to the CONTRACTOR.

	12).-	If the CONTRACTOR does not meet any of its obligations established in the clause named “Financing Sources”.

	13).-	Due to a repeat breach of any of the obligations contained in the “S” Attachment. For the purposes of this cause for rescission, a repeat breach will be understood as lack of compliance by two or more events, or two or more times for the same event, whether or not it is a question of obligations referring to time periods.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		14).-		When as a result of carrying out the contract, the CONTRACTOR causes the death of one or more people, due to its lack of foresight, negligence or failure to comply with any of the requirements or obligations established in the “S” Attachment, or due to a breach of other contract obligations or provisions in the area of Environmental Safety and Health.

		15).-		If as a result of the performance of the work, the death of a worker of the CONTRACTOR or PEP is caused, or of a third party due to the causes attributable to the CONTRACTOR due to its lack of foresight, negligence or failure to comply with the contract obligations or the safety provisions.

		16).-		When the CONTRACTOR causes an accident by failing to comply with the general requirements stated in the following points: II.9; II.10 or II.11.5 of Attachment “S”.

		17).-		When carrying out the contract, the CONTRACTOR commits environmental crimes by failing to comply with any of the requirements of the “S” attachment, other contract obligations or provisions in the area of Environmental Safety and Health.

		18).-		If the CONTRACTOR, being a foreigner, invokes the protection of its government in relation to the contract.

		19).-		If the CONTRACTOR’S workers call a strike or stoppage of work, because it has not properly paid its wages and other labour benefits.

		20).-		For any illegal conduct attributable to the workers of the CONTRACTOR that damage the assets of PEP, without prejudice to a decision from the Public Ministry of the Federation to a report filed by PEP for these acts.

		21).-		In general, due to the CONTRACTOR’S breach of any of the obligations arising from this contract and its attachments, or the laws, agreements, regulations and other applicable obligations;
		When it is PEP who decides to rescind the contract, said rescission will be fully legal by operation of law and without the need for a court declaration. Completion of the procedure that is established in the following clause will be sufficient. When it is the CONTRACTOR who decides to rescind the contract, it will need to go to the corresponding lower court and obtain the respective declaration. In the case of a contract rescission due to causes attributable to the CONTRACTOR, once the respective decision has been issued, PEP will abstain from paying the amounts resulting from services rendered that are not yet settled, until the appropriate settlement is executed, as a precaution and from the time said rescission commences. This shall be done within 30 (thirty) calendar days from the date on which this decision is communicated, in order to proceed to exercise the guarantees. The cost overrun for work not yet performed that is delayed, shall be provided for in the settlement, as well as all that concerns the recovery of materials and equipment that have been delivered to it, where appropriate. Once PEP has notified of the commencement of the contract rescission procedure, PEP will proceed to take immediate possession of the work performed to take charge of the property and the respective facilities and to suspend the work. With or without the presence of the CONTRACTOR, the site supervisor will prepare a support certificate of the status of the work, which shall at least contain what is stated in article 130 of the Regulations of the Law of Public Works and Related Services. This certificate will serve as a basis for the corresponding settlement. The support certificate will be prepared in the presence of a Notary Public.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		PEP may, along with the CONTRACTOR, reconcile the balances arising from the rescission in order to preserve the interests of the parties within the settlement. PEP may record in the settlement the acceptance of the work that the CONTRACTOR has performed until the rescission of this contract, as well as the equipment and materials that had been installed on site or are in the process of manufacturing, provided they are subject to use within the incomplete work, and must in all cases adhere to sections I, II, III and IV of article 132 of the Regulations of the Law of Public Works and Related Services. When the contract is rescinded due to causes attributable to PEP, it will pay for the work performed, as well as the non-recoverable expenses, provided these are reasonable, duly proven and related directly to this contract, as stated in article 62 of the Law of Public Works and Related Services. The cost overrun is the difference between the amount that it would represent for PEP to conclude the pending work with another CONTRACTOR and the cost of the unperformed work at the time this contract is rescinded. In order to determine the cost overrun and its amount, PEP will proceed according to the instructions of article 134 of the Regulations of the Law of Public Works and Related Services. In the event that the contract is rescinded under the terms of this clause, PEP may choose between applying the contractual penalties or the cost overrun as referred to in the above paragraph, under the terms of section II of article 62 of the Law of Public Works and Related Services. The CONTRACTOR will be under obligation to return all documentation to PEP that PEP had delivered to it for performing the work, within a period of 10 (ten) calendar days, from the commencement of the respective procedure.

TWENTY-EIGHT		RESCISSION PROCEDURE. If PEP deems that the CONTRACTOR has violated any of the grounds for rescission that are stated in this contract, it will proceed as follows: 1. The rescission procedure will begin from the time that the CONTRACTOR is notified of the breach of contract that it has incurred, so that within a term of 15 (fifteen) business days, it may provide an explanation as it is entitled and provide the proof that it deems appropriate; 2. Once the term has passed as referred to in the above point, a decision will be made in consideration of the arguments and proof that had been presented; and 3. The decision to (not) rescind the contract shall have a proper basis and grounds and be duly communicated to the CONTRACTOR within 15 (fifteen) business days following the date on which it has given its answer. In the event that PEP decides to rescind the contract, said rescission will take effect from the notification date of the respective decision, so it may proceed according to section II of article 62 of the Regulations of the Law of Public Works and Related Services, without the need for a court ruling. The CONTRACTOR acknowledges and accepts that the public servant that is signing this contract in the name and on the behalf of PEP, or the public servant that has the powers to do so, will be the ones who, where applicable, perform each and every one of the processes related to the administrative rescission procedure of this contract, and indicate the following by way of illustration but not limitation: determining the beginning of the administrative rescission procedure, processing all of the stages of the same and for deciding upon its administrative rescission, and other actions that may be necessary for the administrative rescission procedure.

TWENTY-NINE		INFORMATION CONFIDENTIALITY. All drawings, plans, specifications, designs, data, reports, studies or other documents or information of any nature, in any form, that are developed by the CONTRACTOR or by any of its subcontractors, or provided to the CONTRACTOR by PEP, in relation to the performance of the work hereunder, will be the exclusive property of PEP.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		The CONTRACTOR grants PEP a permanent, transferable, non-exclusive license that is free of fees to use all concepts, products, processes (patentable or not), material protected by copyright (including but not limited to: documents, specifications, calculations, maps, drafts, notes, reports, data, models, samples, plans, designs and software) and information that is the property of the CONTRACTOR, once the performance of the work established in this contract has commenced, and is used by the CONTRACTOR or provided or delivered to PEP by the CONTRACTOR during the provision of the work hereunder. All concepts, products, processes (patentable or not), material subject to protection or protected by copyright (including but not limited to: documents, specifications, calculations, maps, drafts, notes, reports, data, models, samples, plans, designs and software) or information that is the exclusive property of PEP that had been developed, produced or put into practice for the first time by the CONTRACTOR or any of its employees as a result of the performance of the work hereunder, will be the property of PEP once it is created, whether it was delivered to PEP or not at the time it was created. Where applicable, it must be delivered to PEP when it so requires. If PEP so requires in writing, the CONTRACTOR shall do all that is necessary in favour of PEP and in the manner that the latter indicates, to obtain patents or copyrights on any part of the result of the work, provided this part is patentable or may be subject to copyrights. This is with the understanding that the patents, copyrights or any other exclusive right that arises from this contract will invariably be created in favour of PEP. The CONTRACTOR guarantees that said information will be disclosed to its employees only to the extent that they need to know, and that it will not make any announcement, take any photographs or provide information to any member of the public, press, business entity or any other official body, unless it has obtained the prior written consent from PEP. For the purpose of compliance with the above obligations, the CONTRACTOR agrees to take all necessary measures to ensure that its personnel will keep said information in the strictest of confidence, which include but are not limited to: establishing procedures in consultation with PEP to ensure the confidentiality of said information, and taking the necessary measures to prevent its disclosure to any unauthorized party. It also agrees to remedy any unauthorized disclosure, including but not limited to requiring the execution of confidentiality agreements for its employees and instituting security measures. Notwithstanding the foregoing, this confidentiality obligation will not apply to the information of that nature that was known previously by the CONTRACTOR, or that was made available to it on an unrestricted and non-confidential basis, whether it is or may become generally available to the public in a manner other than the erroneous dissemination of the CONTRACTOR personnel. Likewise, both parties acknowledge and accept to consider all information (technical, legal, administrative, accounting, financial, etc.) that is documented in any support material as confidential, which has been developed and is directly or indirectly related to the award procedure, or during the performance of the work, as well as all information or documentation that causes any claim or technical dispute. The confidentiality obligations contained in this clause will remain in effect for a period of twelve (12) years from the completion or rescission date hereof.

THIRTY		CLAIMS AND DISPUTES OF A TECHNICAL OR ADMINISTRATIVE NATURE. Should any claim or dispute of a technical or administrative nature arise related to the interpretation or execution of the contract, the CONTRACTOR may make its written claim to the site supervisor within 10 (ten) calendar days of the occurrence of the difference, so that the latter may make a decision on the difference existing between the parties. If it does not make its claim within the period indicated in this paragraph, the CONTRACTOR waives its right to any latter claim for the difference in question.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860

The CONTRACTOR, for each difference, may only file one claim to the site supervisor, and for its disagreement with the decision to the claim, a technical or administrative dispute under the terms of this clause.

In order to reach a decision on the claim, the site supervisor will perform the pertinent consultations and will bring together the necessary elements and/or documents. The site resident will have a period of 10 (ten) calendar days from the receipt of the request made by the CONTRACTOR to issue his decision in writing and make it known, establishing the contractual basis for his decision.

Once having received the decision from the site supervisor’s office, the CONTRACTOR will have a period of three (3) calendar days to notify of its rejection. Otherwise it will be deemed as accepted.

If the CONTRACTOR accepts the final decision, the site supervisor will proceed to issue the corresponding document, and where applicable, will proceed with the formalization of the corresponding agreement.

If the decision from the site supervisor is not accepted by the CONTRACTOR, it may request that the claim be reviewed as a dispute of a technical or administrative nature.

If the CONTRACTOR chooses to have the claim reviewed as a dispute of a technical or administrative nature, it will discuss the same aspects that gave rise to its claim, and therefore may not add additional, supplementary or complementary petitions, rectify defects, make corrections or replacements to the original claim.

The dispute procedure of a technical or administrative nature will be carried out in the following manner:

The CONTRACTOR shall submit it in writing to PEP, with a copy to the site supervisor, indicating the disputed topics, within 3 (three) calendar days following the date on which the CONTRACTOR had received the final decision of the site supervisor, regarding the resolution of the claim.

The request that the CONTRACTOR may make in this regard shall indicate whether it is a dispute of a technical or administrative nature that is subject to resolution, and will contain the following as a minimum:

a) Itemized description of the facts under dispute, listing them specifically with the documentation that proves them;

b) Clear and precise indication of its intentions, stating the arguments and contractual and legal provisions that support its claim;

c) Documentation verifying the facts upon which its dispute is based, duly organized and identified by the attachment number.

The Office of the Deputy Manager of Contract Services D.N. of P.E.P. may decide for itself on the dispute of a technical or administrative nature which has been exercised by the CONTRACTOR, or delegate this power to the department that it deems pertinent, in which case it will notify the CONTRACTOR of the name of the designated department, sending a copy to the site supervisor.

“WELL MAINTENANCE AND REPAIR WORK, AT THE POZA RICA – ALTAMIRA ASSET OF THE

NORTH REGION” PACKAGE I

CONTRACT No. 424048860


		The Office of the Deputy Manager of Contract Services D.N. of P.E.P. or where applicable, the designated department, will verify that the dispute has been submitted in due time and form, otherwise it will reject it. If the dispute is not rejected, the Office of the Deputy Manager of Contract Services D.N. of P.E.P., or where applicable, the designated department, will notify the CONTRACTOR of the commencement of the dispute procedure, who will have 10 (ten) business days to submit any documents or allegations that it deems necessary, which it had not submitted with its request. The Office of the Deputy Manager of Contract Services D.N. of P.E.P., or where applicable, the designated department, will proceed to analyze and study the topic in dispute and will summon the CONTRACTOR in writing within a period of 3 (three) days from the submission of the dispute, to initiate clarifications. During the clarifications, the parties will meet as many times as necessary and the assigned department shall notify the CONTRACTOR of its decision within 30 (thirty) calendar days following its commencement. If the CONTRACTOR accepts the decision on the dispute of a technical or administrative nature, the Office of the Deputy Manager of Contract Services D.N. of P.E.P., or where applicable, the designated department, will notify the site supervisor, who will issue the corresponding change order, and where appropriate will proceed with the formalization of the respective agreement, thus concluding the procedure for the resolution of claims and disputes of a technical or administrative nature with legal effects on the parties.

THIRTY-ONE		EXPERT DECISION. In the event that any technical dispute should remain between the parties, which decision has not been accepted by the CONTRACTOR and is related to the execution, compliance or non-compliance with the Technical Specifications established for achieving the purpose of this Contract, the parties agree to submit the dispute in question to an Expert Decision. For this, each of them will select one of the experts listed in the Expert List attached to this Contract, for submitting said dispute for its analysis and resolution. If said Experts come to an agreement regarding their resolutions, said agreement will be final and binding upon the parties. In this stage, PEP and the CONTRACTOR shall cover the costs of the Expert that they have selected, regardless of whether they have or haven’t come to an agreement. In the event that the two Experts selected by the parties in the first stage do not come to an agreement regarding their resolutions, both Experts will choose a third one by mutual agreement from the Expert List attached to this Contract, who shall resolve the technical dispute. The resolution of this last Expert will be final and binding upon the parties and all of the costs that have been generated in this regard will be covered by PEP and the CONTRACTOR in equal parts.

THIRTY-TWO		CONCILIATION. The CONTRACTOR will be entitled to file a complaint to the Ministry of the Civil Service, if it deems that PEP has breached the terms and conditions agreed to in the contract. The conciliation procedure will be substantiated in terms of the provisions of articles 89 to 91 of the Law of Public Works and Related Services. In the event that the parties come to conciliation, the respective agreement will be binding upon them and their compliance may be demanded by the corresponding legal channel. Otherwise their rights will remain intact, so that they may exercise them at the respective lower court.

THIRTY-THREE		APPLICABLE LAW AND JURISDICTION. This contract will be governed by the Federal Laws of the United Mexican States and other provisions that arise therefrom that are in force. In the event that any dispute should arise that is related to this contract, the parties expressly agree to submit to the jurisdiction of the Federal Courts of Poza Rica de Hgo. Ver. Therefore, the CONTRACTOR irrevocably waives any jurisdiction that may pertain to it due to its present or future domicile, or for any cause.

THIRTY-FOUR		CONTINUATION OF THE WORK. Unless there is provision that states otherwise in this contract, or there is a written order issued by PEP, the CONTRACTOR shall continue with the services and comply with its obligations pursuant to this contract, notwithstanding the fact that proceeding(s) have been initiated for resolving claims and disputes of a technical or administrative nature, or disputes according to this contract.

The foregoing is without prejudice to the withholdings that PEP is obligated to pay according to the laws in this area.

THIRTY-SIX		TRAINING AND CONDUCT OF THE CONTRACTOR PERSONNEL. All CONTRACTOR personnel who perform any activity within PEP facilities as a result of the performance of the work hereunder will be bound to comply with the Industrial Safety, Occupational Health and Environmental Protection provisions indicated in Attachment “S” “Safety, occupational health and environmental protection obligations of the Suppliers or Contractors that perform activities at the facilities of PEMEX Exploración y Producción”, without prejudice to the other legal provisions that the CONTRACTOR is under obligation to meet, as well as those that PEP may issue following the signing of this Contract. Likewise, the CONTRACTOR is under obligation to prove to PEP, prior to the commencement of the work, that the personnel who will perform the work have received training by a duly authorized company in the last 12 (twelve) months, according to the provisions of the Federal Labour Law, in the areas that are related to the work to be performed, as well as in the areas of Industrial Safety, Occupational Health and Environmental Protection. In the event that the CONTRACTOR does not reliably prove to the satisfaction of PEP that its personnel have received training in the areas of Industrial Safety, Occupational Health and Environmental Protection, it may not enter PEP’S facilities, and therefore any delay in the work execution schedule arising from this breach of contract will not be grounds for deferring the commencement date of the same or extending the contract execution period. The CONTRACTOR will take all measures to prevent illegal, seditious or objectionable behaviour by the personnel under its charge, in order to maintain discipline among the personnel who perform the work, whether or not they are in any of the facilities of PEP.

THIRTY-SEVEN		NOTIFICATIONS. The parties undertake to communicate in writing all information that is generated as a result of compliance and execution of this contract, pursuant to the following: Communications to PEP: Communications regarding technical issues shall be delivered personally to the site supervisor or the person that he may designate, personally or through any other means of messaging that ensures its receipt at the following address: Boulevard Xxxxxxxx Xxxxxx S/N, a xx xxxxxxx xx Xxxxxxxx X.X. 00000, Poza Rica, Veracruz.

I. TECHNICAL ASPECT

Inclusion of the Gulf Tertiary Oil Project

The following items are within the works performed under contract no. 424048860 and required to be included in the Tertiary Gulf Oil Project:

•

Major repairs

•

Minor repairs

•

Pneumatic pumping conversion

•

Mechanical pumping conversion

•

Rehabilitation of pneumatic pumping

•

Rehabilitation of mechanical pumping

•

Water injector conversion

•

Change of flowing rig

•

Well improvement identification

•

Infrastructure works (reconditioning of paths and platforms)

The need to include the Tertiary Gulf Oil Project is based on the need to cover a substantial increase to PEP’s operation contracts; the latter is shown in the existing project portfolio. The following chart shows the operation contract for the Tertiary Gulf Oil Comprehensive Asset that covers 4,071 major repairs and 17,777 minor repairs from 2009 to 2023.


ATG Comprehensive Asset	2009	2010	2011	2012	2013	2014	2015	2016	2017	2018	2019	2020	2021	2022	2023	TOTAL
Major repairs	501	300	300	300	300	300	300	300	300	300	300	300	300	300	300	4,701
Minor repairs	274	1,396	1,294	1,127	1,193	1,224	1,226	1,168	1,130	1,216	1,099	1,270	1,235	1,245	1,080	17,177

TOTAL	775	1,696	1,594	1,427	1,493	1,524	1,526	1,468	1,430	1,516	1,399	1,570	1,535	1,545	1,380	21,878

Thereafter and based on the need to replace and increase production fees of the North Region for this year in the Tertiary Gulf Oil Comprehensive Asset, 775 well repairs were programmed, 501 major and 274 minor repairs among them, and to perform that work volume 34 repair equipment units were programmed; and since PEP does not have sufficient infrastructure to take care of that volume, operation fronts to work on the Tertiary Gulf Oil Comprehensive Asset are programmed to be formed as follows:


SCHEME	EQUIPMENT
Management	8
Contract 424047834 (Replacement Bid I Contract 424047834) (Replacement Bid II Contract 424047834)	14 (7 (7	) )

Contract 424048860	6
Contract 424048861	6

Total	34

This contract shall contribute with an average of 18 monthly interventions in xxxxx located in locations of the ATG Comprehensive Asset and be performed by operating 6 well repair equipment units, thus contributing with 18% of the total interventions to be performed in this Asset in 2009 and 2010 respectively. This contract currently operates with 4 repair equipment units in the Poza Rica – Altamira Comprehensive Asset, and the 6 equipment units contemplated to work in the ATG Comprehensive Asset are independent from them.

By including the Tertiary Gulf Oil Project, an insertion is necessary in the third paragraph of point 3.5 of exhibit “B” General Work Specifications in order to agree with Contractor on the possibility to request additional equipment as follows:

It reads:

It should read:

“Pursuant to operation requirements of the Yearly Intervention and Investment Program, PEP may request CONTRACTOR 1 (one) up to 2 (two) additional well repair equipment units to total 6 (six) equipment units supplied by Contractor, either together or in a separate manner, and this shall be informed to CONTRACTOR and the latter shall supply the same no later than 60 days thereafter”. However, in the event it is required due to operation requirements, PEP may, by common consent with contractor, request him additional equipment besides the aforementioned equipment units.

Works with Steel Line Units

Work concepts that UOPRA has to include in the aforementioned contract are mechanical operation works with steel line units for land oil xxxxx in their repair, maintenance, termination and/or non-equipment operation stage, using mechanical tools in 2 ³/8”, 2 ⁷/8”, 3 ¹/2” and 4 ¹/2” production rigs in xxxxx of the North Region, since said work concepts are necessary to contribute to meet PEP’s operation programs.

The purpose of performing these works is to give support to oil well repair and maintenance operations where several mechanical operations have to be worked out in production rigs that are securely operated and where performance of the same requires the use of sophisticated tools in different diameters and technical specifications depending on the rig to be operated.

The incorporation of works with steel line units to contract no. 424048860 results from the need to meet a 27% increase in well repair operations programmed for this year’s POT-I with respect to the former year, since PEP does not have sufficient units to meet mechanical operations resulting from repair works currently performed by UOPRA with a total of 20 equipment units, because it only has 7 steel line units, not being sufficient to comply with this program.

AIPRA

In the same way in which there was an increase in this year’s programmed activities, there is an increase to the following years. This may be observed in the current project portfolio as shown in Chart 1. That is why it is important to have steel line works, since they will help to meet operation programs in subsequent years.

It should be noted that performing works with a steel line unit aims to strengthen the strategic plans of the Poza Rica-Altamira and the Gulf Tertiary Oil Comprehensive

Assets and timely meet the established commitments and goals by avoiding waiting periods in well repair, maintenance and termination operations currently being suffered for a lack of the required steel line units, and thereupon a timely intervention that allows optimization and continuity to well repair activities, among other primary activities aimed at maintaining hydrocarbon production standards.

Works with steel line units shall contribute a good degree to the success of repair, maintenance and completion works of North Region Xxxxx and thus contribute to meet Operation Programs, since as stated hereinabove, waiting times are to be avoided, being the same non-productive times that do not generate value to the project.

The contract currently has a $28’264,360.79 pesos (twenty eight million two hundred sixty four thousand three hundred and sixty pesos 79/100 Mexican currency) fiscal year plus US$7’365,711.53 (seven million three hundred sixty five thousand seven hundred eleven US dollars 53/100) highlighting that there is a sufficient amount to guarantee continuity of operation programs of the Poza Rica-Altamira Comprehensive Asset in an efficient and secure manner.

In order to comply and provide continuity to PEP’s operation contract regarding oil well repair and maintenance work in the North Region, it is requested to include the Gulf Tertiary Oil Project into contract no. 424048860 with an increase amounting to US$24’999,998.33 (twenty four million nine hundred ninety nine thousand nine hundred ninety eight US dollars 33/100). This amount covers programmed works to be performed in the ATG Comprehensive Asset in 2009 and is covered by budget projects shown in chart no. 2. It is worth mentioning that due to budget provisions, the amount regarding works to be performed in 2010 could not be obtained and will be pending.
