If on expiry of this Contract there should remain Buyer’s Deferred Quantities pending recovery, the Buyer may recover the corresponding quantities after such expiry, within a maximum period of twelve (12) months, as may be extended by such period of time (if any) during which the Sellers fail to deliver the Deferred Quantities (as requested by the Buyer) for reasons other than Force Majeure.

5.5At any time that the most recently determined weekly YUP closes below one hundred and twenty-five Dollars (US$125) per tonne, the Buyer shall have the right to suspend the application of a take or pay charge by giving the Sellers not less than seven (7) Days’ prior written notice (a “Suspended TOPQ”). After such written notice is given, a Suspended TOPQ shah be in effect on each Day from the Day set forth in such notice until the earlier of (a) seven (7) Days after the Day on which the Buyer gives the Sellers written notice that it is terminating the Suspended TOPQ and (b) seven (7) Days after the most recently determined YUP closes above one hundred and twenty-five Dollars (US$125) per tonne. The volume of Gas not taken by the Buyer during a Suspended TOPQ can be used freely by the Sellers. Notwithstanding anything to the contrary contained herein, in the event Suspended TOPQs are in effect for more than three hundred and sixty-five (365) Days, in the aggregate, the Sellers shall have the right to terminate this Contract by giving the Buyer at least thirty (30) Days’ prior written notice.

For the purposes of this Point 5.5, the TOPQ for any Contractual Month in which a Suspended TOPQ is in effect shall equal: (i) the product of (A) the DCQ designated by the Buyer for the applicable Contractual Year multiplied by (B) the TOPP designated by the Buyer for the term of this Contract, multiplied by (C) the number of Days in such Contractual Month other than Days in Which a Suspended TOPQ was in effect; less (ii) any quantity of Gas that are the Buyer’s Excused Quantities for such Contractual Month.

5.6Subject to Point 19.6, if the Buyer fails to comply with its obligations to take Gas from the Sellers in accordance with this Contract and such failure is not otherwise excused under this Contract, (a) the Sellers’ remedies will be limited solely to those described in this Article Five and no additional penalties will apply; (b) the Buyer shall not be responsible for any Consequential Damages (as defined in Point 19.6); and (c) the Sellers hereby waive any claim of indemnity that may arise from the Buyer’s failure to take the TOPQ of the Gas in accordance with this Article 5.

ARTICLE VI

DELIVER OR PAY

6.1The Deliver or Pay Quantity is the amount of Gas scheduled by the Buyer for delivery in any Contractual Month that the Sellers must pay for if not delivered during such Contractual Month.

6.2On any Day during the Term, the Sellers shall be excused from any obligation to deliver a quantity of Gas (“Sellers’ Excused Quantities”) equal to the sum of: (i) any quantities of Gas scheduled by the Buyer but not delivered by the Sellers due to Force Majeure affecting the Sellers, including without limitation any quantities of Gas that cannot be delivered for the reasons set forth in Point 12.2(d) whether or not Force Majeure was declared by the Sellers; plus (ii) any quantities of Gas scheduled by the Buyer but which the Buyer fails to take for any reason, other than quantities of Gas properly rejected by the Buyer or the Transporter at the Receiving Point for not satisfying the quality specifications; plus (iii) the amount, if any, by which the DCQ exceeds the quantity of natural gas scheduled by the Buyer for that Day; plus (iv) any quantities of Gas that the Sellers are not required to deliver due to Scheduled Maintenance in accordance with Point 4.3.

6.3The DOPQ for any Contractual Month shall be equal to the sum for all of the Days in such Contractual Month of: (i) the DCQ; less (ii) the quantity of Gas actually delivered by the Sellers to the Buyer at the Receiving Point on each Day of such Contractual Month; less (iii) any quantities of Gas that are the Sellers’ Excused Quantities for each Day of such Contractual Month.

6.4On any Day during the Term, if any Gas is tendered, for delivery at the Receiving Point that does not meet the Gas quality specifications and the Transporter or the Buyer rejects such Gas, then any such rejected Gas quantities shall be considered as quantities of Gas that were not delivered by the Sellers for such Day, and will not be considered as part of the Sellers’ Excused Quantities for such Day.

6.5If in any Contractual Month the DOPQ for such Contractual Month is a non-zero positivequantity, then the Sellers may:

(i)provided the Buyer can make use of the Gas at the Plant, deliver to the Buyer quantities of Gas up to 100% of the DOPQ (“DOP Make Up Gas”), in which case the Buyer shall not be obligated to make any payment to the Sellers in respect of such DOP Make Up Gas. The performance of this option shall not increase the corresponding TOPQ; or

(ii)pay to the Buyer a Deliver-or-Pay charge equal to the product of: (x) the Gas Sale Price multiplied by (y) the DOPQ for such Contractual Month. Any such Deliver-or-Pay charge that is undisputed may be set-off against the invoice corresponding to the Gas consumption of the following month in which the Sellers incurred a DOP charge; provided, however, that if (i) the Buyer is not in breach of its payment obligations hereunder and (ii) there are not enough amounts invoiced by the Sellers so that such charges cannot be set-off against any such invoices for a period of ninety (90) days following the last day of the Contractual Month in which the DOP charge was incurred, then any such undisputed Deliver-or-Pay charge that remains unpaid after such ninety (90) day period, shall be paid by the Sellers to the Buyer within ten (10) Business Days as from the lapse of such 90-day period.

6.6Subject to Point 19.6, if the Sellers fail to comply with their obligations to deliver Gas to the Buyer in accordance with this Contract and such failure is not otherwise excused under this Contract, (a) the Buyer’s remedies will be limited solely to those described in this Article Six and compensation of the Buyer by the Sellers for any additional transportation and/or distribution costs (if any) actually incurred by the Buyer as a result of such failure, and no additional penalties will apply; (b) the Sellers shall not be responsible for any Consequential Damages (as defined in Point 19.6); and (c) the Buyer hereby waives any claim of indemnity that may arise from the Sellers’ failure to deliver the DOPQ of the Gas in accordance with this Article Six.

6.7The Sellers agree that, provided they are producing gas at the Camisea Reservoir and injecting it into the Transporter’s pipeline, they will be obligated to sell Gas hereunder to Buyer up to the MDCQ. In cases where the Sellers cannot make available to the Buyer, at the Receiving Point, the quantity of Gas nominated for each Day, up to the agreed MDCQ, due to Force Majeure or Emergency Events (as defined hereunder), the priority for available supplies of Gas shall be determined (a) if there is Applicable Law or binding legal direction of any Government Authority, according to such Applicable Law or such binding legal direction of the Government Authority; or (b) if there is no Applicable Law or binding legal direction of any Government Authority, on a pro-rata basis, considering the Gas quantities properly nominated for the relevant Day by Buyer pursuant to the Contract and by other buyers under all existing gas supply contracts from the Camisea Reservoir between Sellers and third parties. For the avoidance of doubt, nothing in this Section 6.7 shall affect nor increase or decrease the Sellers’ liabilities under Sections 6.1, 6.2, 6.3, 6.4, 6.5 and 6.6.

“Emergency Event”: means an emergency event, as defined in the Glossary of the Hydrocarbons Sector (“Glosario, Siglas y Abreviaturas del Subsector Hidrocarburos”), as approved by Supreme Decree No. 032-2002-EM, as amended by Supreme Decree No. 048-2009-EM, in each case as effective as of the date of this Agreement. For the avoidance of doubt, an Emergency Event does not include shortages of Gas that may arise (i) due to the Sellers’ over commitment to deliver Gas to other customers in excess of the amount of Gas they are capable of producing at the Camisea Reservoir and injecting into the Transporter’s pipeline (whether pursuant to gas supply agreements or otherwise) or (ii) due to the capacity of the Sellers to sell Gas at a higher or more favorable price than that established herein.

ARTICLE VII

NOMINATIONS

7.1Subject to Point 3.5, the Buyer shall nominate the daily quantities of Gas by twelve o’clock (12 p.m.) on the Business Day immediately preceding the Day on which the Gas volumes shall be made available to it by the Sellers at the Receiving Point. The Sellers’ Coordinator shall confirm such quantities before 2 p.m. on the Business Day the Buyer nominates the daily quantities of Gas. This activity shall be done each and every Business Day from the Starting Date of Gas Supply. If the Buyer does not make such Nomination on a certain Business Day, this shall mean it is nominating the quantity nominated on the preceding Business Day or the last quantity the Buyer had nominated. If the Sellers’ Coordinator does not confirm the Nomination by the Buyer, it shall be understood as confirmed.

7.2In those cases where the Sellers agree with the Transporter on an operational balance, they shall implement an account to inject Gas into the Transporter’s pipeline from which the Sellers may perform the delivery of Gas to the Buyer, following authorization of the Transporter. The Sellers’s Coordinator shall be responsible for securing authorization from the Transporter and coordinating with it.

7.3In none of the Contractual Days shall the Sellers be obligated to deliver or the Buyer totake Gas volumes exceeding the MDCQ, unless the Parties agree otherwise.

ARTICLE VIII

RECEIVING POINT - TRANSFER OF OWNERSHIP, MEASUREMENTS.

8.1The Gas shall be delivered by the Sellers to the Buyer at the Receiving Point.

8.2The Sellers may modify the Receiving Point, subject to the consent of the Buyer, not to be unreasonably withheld and provided such modification shall not affect the supply of Gas to the Plant, including the quality standards set forth in Annex A and the ability to conduct accurate measurements in accordance with this Article Eight. Any costs caused by the change shall be borne by the Sellers and not by the Buyer.

8.3Subject to Point 6.5, by 6:00 a.m. on the Day following the Day when the Nomination is made (or deemed made) by the Buyer in accordance with Point 7.1 and confirmed (or deemed confirmed) by the Sellers in accordance with Point 7.1, the Sellers shall make the quantity of Gas set forth in such Nomination available to the Buyer at the Receiving Point. The transfer of ownership and risk over the Gas shall pass from the Sellers to the Buyer once the Gas has been made available to the Buyer at the Receiving Point in accordance with the preceding sentence. The Buyer shall have exclusive ownership and control of the Gas once the Gas has been made available to the Buyer at the Receiving Point. The Buyer will be responsible for the Gas transportation from the Receiving Point to the Plant.

8.4The Sellers shall maintain a register of the measurements and quantities of Gas delivered by the Sellers to Buyer at the Receiving Point which register will be used by the Sellers to prepare and issue the invoices in accordance with Article Eleven. Such measurement system shall be approved by the Transporter.

8.5The quantity and heat contents of the supplied Gas shall be determined at the Receiving Point by using the Sellers’ Measuring Equipment, which the Sellers shall, or shall cause to, install, operate and maintain under their responsibility at the Receiving Point, duly equipped and operated as required by Applicable Law. Each Party has the right to inspect, verify and participate in the adjustments and audits of the Sellers’ Measuring Equipment, which shall be performed with reasonable frequency, prior notice and without unnecessarily interrupting or interfering with the Sellers’ activities related to this Contract.

8.6The price, the quantities consumed, the billing and the DCQ, MDCQ, DOPQ and TOPQ shall be adjusted in energy units (MMBTU). The installed Sellers’ Measuring Equipment shall facilitate such calculation.

8.7The Buyer shall install, operate and maintain under its responsibility and within the Plant the Measuring Equipment solely for the purposes of measuring the amount of Gas used to produce electricity for the Plant for the purposes of Annex B, Point 5. The Sellers have the right to inspect, verify and participate in the adjustments and audits of such Measuring Equipment, which shall be performed at reasonable frequency, with reasonable prior notice and without unnecessarily interrupting or interfering with the Buyer’s activities at the Plant.

ARTICLE IX

QUALITY

9.1The Sellers shall deliver the Gas in accordance with the quality standards set forth in Annex A and shall maintain the quality of gas within the specifications set forth in Annex A.

9.2In the event that the quality of Gas does not conform to the standards of Annex A, the Sellers’ Coordinator shall notify the Buyer as soon as reasonably possible that the Gas available for delivery does not meet the quality specifications of Annex A, providing details on the nature and magnitude of the difference, the reason for the failure to comply and the probable duration of such situation. Any amount of Gas that does not meet the specifications and is rejected by the Buyer or the Transporter in accordance with Point 6.4 shall be considered to have not been made available by the Sellers for the purposes of Article Six.

9.3The Buyer will be deemed to have rejected the Gas that does not meet the specifications, in which case the remedies of the Buyer will be determined in accordance with Article Six and Point 13.2, unless the Buyer at any time notifies the Sellers that the Buyer accepts the total or partial delivery of such Gas, in which case the Sellers shall deliver the Gas only after receipt of Buyer’s acceptance. If the Buyer accepts the Gas that does not meet the specifications, unless such Gas is rejected by the Transporter in accordance with Point 6.4, the Buyer will not have right to make any future claim with respect to such Gas and the provisions of Article Six with respect to non-conforming Gas will not apply. The Buyer’s partial or total acceptance of non-conforming Gas at any time shall not be construed to limit its ability to reject any non-conforming Gas that may be delivered by the Sellers at any future time.

ARTICLE X

PRICE - TAXES

10.1The Gas Sale Price shall be determined according to the conditions stated in Annex B. For the purposes of Point 5 of Annex B, the YUP will be determined in accordance with its definition. Neither the Buyer nor the Sellers will undertake any activities or roles in an effort to lobby the Government Authorities to alter the Gas Sale Price agreed in this Contract.

10.2The Gas Sale Price shall not include any indirect consumption tax that may be applicable to the transference of Gas and which by Applicable Law must be shifted by the Sellers to the Buyer, such as Impuesto General a las Ventas, Impuesto de Promoción Municipal, Impuesto Selectivo al Consumo, and any other tax of similar nature, which shall be added to the pertinent invoicing.

10.3With respect to taxes, it is further agreed by the Parties that:

(a)the Sellers shall be liable for all taxes, rates, encumbrances, contributions, royalties and other tax costs, present and future, which shall be applicable to and/or originated with respect to the Gas prior to the Receiving Point, including all taxes specific to the activities of producing and/or selling the Gas, except for any indirect consumption tax that may be applicable to the transference of Gas and which by Applicable Law must be shifted by the Sellers to the Buyer, such as Impuesto General a las Ventas, Impuesto de Promoción Municipal, Impuesto Selectivo al Consumo, and any other of similar nature; and

(b)the Buyer shall be liable for all taxes, rates, encumbrances, contributions, royalties and other tax costs, present and future, which shall be applicable and/or originated with respect to the Gas at and after the Receiving Point, including all taxes specific to the activities of manufacturing and selling of nitrogen fertilizers, and/or buying of Gas. For the avoidance of doubt, the Buyer will not be responsible for the income tax resulting from the Sellers’ sale of Gas to the Buyer or the royalties on natural gas production.

ARTICLE XI

INVOICING AND PAYMENT

11.1The quantities of Gas acquired by the Buyer shall be measured by the heat content (BTU), referring to the Higher Calorific Value, and then invoiced in Dollars. The invoice shall be issued on the basis of measurements made at the Receiving Point by the Sellers’ Measuring Equipment, and shall be certified by the Transporter.

11.2The Sellers shall provide monthly invoices to the Buyer, all amounts in Dollars, due and owing under this Contract for each Contractual Month. Within ten (10) Days immediately after the last Day in each Contractual Month, the Sellers shall bill the Buyer for the quantities of Gas delivered in such month specifying the quantity corresponding to the TOPQ, if applicable, also taking into account the provisions of Article Five and Article Six. The Buyer shall pay each such monthly invoice in Dollars on or before the Day that is ten (10) Days after Buyer’s receipt of each invoice. If the due date falls on a Saturday, the payment shall be made on the preceding Business Day.

With respect to any amounts due from the Sellers to the Buyer, the Buyer may invoice the Sellers in Dollars, monthly, and the Sellers shall pay in Dollars on or before the last Day of the ten (10) Days after Sellers’ receipt of each invoice or set off the undisputed amounts due against any amount due from Buyer to Sellers under this Contract. If the Sellers have to pay any amount to the Buyer, if the due date falls on a Saturday, the payment shall be made on the preceding Business Day. If the due date falls on a Sunday or a non-working holiday, the payment shall be made by the following Business Day.

11.3Invoices issued by the Sellers shall include the Gas supplies made during the pertinent period, detailing the volumes of Gas, the heat contents, the unit price, discounts and the total amount. Should the Buyer require additional information with respect to the billing and/or measurement, such information shall be provided by the Sellers within ten (10) Business Days after submission of such request.

11.4All payments or amounts to be made or discharged hereunder in cash, shall be made in immediately available, unencumbered and freely transferable US Dollars funds, made not later than 12:00 pm (noon) City of Lima time on the Day in question to the nominated account.

Without prejudice of the foregoing, and without limiting obligations to discharge and settle in US Dollars hereunder, the Parties undertake, in the event of any foreign exchange restriction or prohibition in Peru being in effect which restricts the ability to perform US Dollar denominated payment obligations, that the paying Party shall (x) utilize and implement every available lawful mechanism in Peru (but solely to the extent it is commercially reasonable to do so) for the acquisition of US Dollars in any local or international exchange market and (y) if there are no available lawful mechanisms in Peru, or it is not commercially reasonable to implement them, each Seller hereby agrees that the Buyer shall be required to make any and all US Dollar denominated payments hereunder to such Seller at an account or address outside Peru; provided that, in each case, no default of the provisions of this Agreement shall be deemed to have occurred due to any delay in payment of the amounts due while the paying Party is fulfilling, complying or following any of the lawful mechanisms available in Peru for the acquisition of US Dollars. All costs including any taxes, relating to any transaction related to this clause shall be borne by the paying Party.

In case of any failure by a Party to make a timely payment of any amount owed to the other Party under this Contract (the “Defaulted Amount”), such amounts shall accrue interest for the period of time (the “Defaulting Period”) beginning on the Day immediately following the due date (the “Rate Fixing- Date”) under this Contract and continuing until the date such amounts are paid, without the need of a judicial or extrajudicial demand. The interest owed on any such amounts shall accrue at an annual percentage rate equal to Default Interest Rate. In case of failure by the Buyer to pay the undisputed portion of any three (3) monthly invoices outstanding at any one time, the Sellers shall be able to interrupt the supply of Gas upon ten (10) Business Days’ notice until such time as the Buyer has cured such failure.

11.5In case of any disputes with respect to any of the invoices submitted in accordance with this Article 11, the Buyer shall pay the undisputed sum within ten (10) Days of receipt of such invoice and may file a written claim to the Sellers with respect to the disputed portion of such invoice.

11.6If, within ten (10) Days after the due date with respect to any invoice, the Buyer has not filed any written claim in accordance with Point 11.5, the Buyer shall fully pay the disputed amount without prejudice to the exercising of its right to file a claim at a later date.

11.7In the event the Buyer has filed a written claim with respect to any invoice which has been accepted by the Sellers in writing, invoicing differences shall be applied to the invoice of the following Contractual Month.

11.8If, as a result of a written claim with respect to any invoice, the Parties are not able to reach an agreement with respect to the disputed amount, they may submit the Dispute to arbitration as provided for in Article Fourteen.

11.9If the award settling any Dispute initiated in accordance with Point 11.8 is unfavorable to the Buyer, it shall pay the amount claimed and unpaid, plus the default interest established pursuant to Point 11.4, taking into account the application of the Default Interest Rate as from the due date on which the claimed amount was to be paid. Otherwise, the Sellers shall reimburse the Buyer for any amount paid which claim is favorable to the Buyer, adding thereto the Default Interest Rate calculated as from the date on which the Buyer made such payment in favor of the Sellers.

11.10An account statement or invoice may only be questioned within a term of twelve (12) Contractual Months following their receipt. The Buyer shall notify the Sellers of a mistake made and request the pertinent correction. If a term of twelve (12) Contractual Months following the receipt of notice has elapsed, an invoice or account statement shall be considered correct, final and acceptable for both Parties, except for the items, as applicable, which have been objected to in accordance with the foregoing.

ARTICLE XII

FORCE MAJEURE

12.1None of the Parties shall be responsible for non-compliance or for partial, late or defective compliance with an obligation during the time such Party is affected by a Force Majeure event, provided such Party has provided evidence that such cause impeded its due compliance.

12.2For the purposes hereof, Force Majeure shall include events beyond the reasonable control of a Party and which cannot be avoided by due diligence and reasonable care of such Party, including (but not limited to), among others:

(a)Any act of external war (whether declared or not), invasion, armed conflict, roadblocks, embargo, revolution, riots, insurrection, civil commotion or acts of terrorism or threat thereof, civil disturbance, sanction or any other restriction on the export of goods.

(b)Any workers’ strike (whether declared or not, legal or not) affecting the Parties hereto.

(c)Any earthquake, flood, storm, hurricane, tornado, thunderstorm, fire, explosion, extreme weather or similar event, provided it directly affects the Sellers’ or the Buyer’s facilities, in whole or in part.

(d)A Force Majeure event declared by the Transporter or the technical impossibility by the Transporter to carry the Gas (including any interruption, curtailment or cessation of transportation, but excluding any maintenance works in respect of the Transporter in excess of the periods contemplated by Article 4), which may include the transportation system of Gas or natural gas liquids by pipeline, and/or the facilities of the Distribution Company by the pipeline network in the Department of Ica, if applicable, as from the moment it occurs, provided it prevents the Buyer from receiving the agreed TOPQ or prevents the Sellers from complying with their commitment to supply the Gas as per this Contract, as applicable.

(e)In the case of the Sellers, the loss, serious damage or the inoperability of the processing plants of Las Malvinas and/or Pisco, including the freezing or rupture of the pipelines and auxiliary facilities related to the transportation of unprocessed Gas from the Camisea Reservoir to Las Malvinas plant.

(f)In the case of the Sellers, damage or destruction of the Camisea Reservoir (including (i) inexistence, loss or failure of gas reserves and (ii) depletion or lack of economically recoverable Gas and natural liquids in the Camisea Reservoir, in each case, as a consequence of such damage or destruction) due to events beyond the reasonable control of the Sellers (provided that, it shall not be a Force Majeure event if it results from the Sellers’ commitments to sell Gas beyond the gas reserves existing at the time of each sale, as they were described in the most recent certification of such reserves made by a recognized independent international petroleum engineering firm in accordance with standard industry practices at the time of relevant sale).

(g)The loss, serious accidental damage or inoperability of the Plant or inability of any of its facilities (including port facilities, whether or not owned by the Buyer) to receive the Gas, store or dispatch the products of the Plant.

(h)Failure to obtain Government Authorizations and/or private authorizations (excluding the invalidity, refusal or expiration of any approval or permit from any Government Authority or the impossibility of obtaining them, to the extent the affected Party may request and obtain, maintain or execute, or was able to reasonably request, obtain, maintain or execute such approval or permit, or in the event of failure to act by the affected Party, failure to observe the terms and conditions of any existing approval or authorization, or any other legal requirement).

(i)The acts or failures to act of any Government Authority, the effect of which would prevent, delay or make unlawful or commercially uneconomic Sellers’ or Buyer’s performance hereunder, or would require

the Sellers or the Buyer, in order to comply with said act, to take measures which are commercially unreasonable in the circumstances.

12.3For the avoidance of doubt, Force Majeure events shall not include:

(a)The breakdown or failure of equipment caused by normal wear and tear, lack of adequate maintenance of the equipment or spare parts.

(b)The unavailability or lack of funds.

(c)The capacity of the Sellers to sell Gas at a higher or more favorable price than that established herein, or the capacity of the Buyer to acquire the Gas at a lesser or more favorable price than that established herein.

12.4A Force Majeure event shall not relieve the Parties from the duty of compliance with any of their duties not partially or totally affected by such events. In such case, the affected duties shall be suspended for the entire time the Force Majeure event lasts and the term of this Contract shall be extended, if the Parties so agree and if possible, for a period equal to the event giving rise to such suspension.

12.5The Party invoking a Force Majeure event shall inform the other Party regarding the facts constituting such Force Majeure event within forty-eight (48) hours following its occurrence, providing details of the event and stating the obligations the execution of which is or will be impeded, delayed or prevented, and (both in the original notice and any additional notices) indicating: (i) an estimate in good faith of the likely duration of the event of Force Majeure and the period during which its performance may be suspended or diminished, including, to the extent that it may be communicated or established, the estimated scope of such diminishment in performance; and (ii) the details of the schedule to be implemented and any other corrective measure already taken to assure the total resumption of the normal performance established herein. Delivery of such notice by the Sellers, through the Sellers’ Coordinator, shall constitute a declaration by the Sellers that they are entitled and authorized to make such determination and issue said declaration. In order to resume the normal performance of this Contract as soon as possible, the affected Party shall adopt all reasonable commercial measures according to the circumstances and for the purposes thereof, taking into account the consequences arising from such event of Force Majeure for the affected Party. Before the resumption of normal performance, the Parties shall continue complying with their obligations as established herein to the extent that these are not exempted or prevented by said event of Force Majeure. The failure by an affected Party to submit a notice of a Force Majeure event in accordance with this Point 12.5 will not prevent such Party from claiming the Force Majeure event, unless the other Party can show that it was materially prejudiced and suffered actual damages as a result of such failure.

12.6If (i) an event of Force Majeure prevents a Party declaring a Force Majeure (an “Affected Party”) from supplying (in the case of the Sellers) or receiving (in the case of the Buyer) of any amount of Gas provided herein for an uninterrupted period of more than twelve (12) Contractual Months and (ii) there is no reasonable prospect that such supply or receipt (as the case may be) be resumed, the unaffected Party shall be entitled, though not obliged, to terminate this Contract after ninety (90) Days as from the receipt of such notice at any moment following the expiration

of such period of twelve (12) Contractual Months. Any valid termination shall not result in any liability for the unaffected Party. For the avoidance of doubt, the Affected Party shall not be entitled to terminate this Contract under this Point 12.6.

12.7In the event that one of the Parties is not in agreement with the qualification of the event as a Force Majeure event, such party shall initiate the procedure for settling Disputes in accordance with Article Fourteen, within fifteen (15) Business Days from the notice of the event issued by the Party invoking it. Once such period elapses without any objections having been raised by the Party notified of the event and provided that Point 12.5 has been complied with, it shall be understood that such Party has accepted the event as such, unless facts or circumstances discovered by such Party after said period clearly demonstrate that the event does not constitute a Force Majeure event.

12.8Once the claimed and accepted Force Majeure cases are settled, the Parties shall recommence full compliance with their contractual duties with reasonable promptness, and none of the Parties shall have the right to request any services or claim indemnities for the period of inactivity.

12.9No Force Majeure event can be claimed in order to justify the default on payment of sums of money.

Where:

PPBt = Base Floor Price at the Fiscalization Point, applicable to the new period. PPB = Base Floor Price defined in numeral 1 of the present Annex (1.00 US$/MMBTU)

FA = Adjustment Factor determined as a result of:

FA = (0.60 * Ind1j /Ind 10+ 0.40 * Ind2j/Ind2o)

Ind l= Arithmetic Average of the Oil Field and Gas Field Machinery Index, (WPS1191), published by the Department of Labor - USA, corresponding to the period (j) or (0).

Ind2= Arithmetic Average of the Fuels and related products and power Index, (WPU05) published by the Department of Labor - USA, corresponding to the period (j) or (0).

(j) = Period of 12 months published before the adjustment period.

(o) = Period between December 1999 and November 2000.

Period of determination of Adjustment Factor (FA):

The Adjustment Factor (FA) shall be determined for each calendar year on the first Business Day of each calendar year with the last 12 published indexes, which for the purpose of these calculation shall be considered final.

If the Adjustment Factor for any year results in FA < 1, then it shall be considered that FA = 1.

4.FLOOR PRICE

Floor Price = PPBt x Factor “A” x Factor “B”

5.WELLHEAD FINAL PRICE

Wellhead Final Price (US$/MMBTU) = Wellhead Base Price * Factor “A” * Factor “B”

Where:

Wellhead Base Price in US$/MMBTU for Gas used as a feedstock for the Petrochemical Plant or for other uses within the Petrochemical Plant, other than Gas used for the generation of electricity that will be used exclusively within the plant, shall be the greatest of a), b) or c):

a) 3,09

b) 3,09 + [(YUP — 350) * 0,01619]

c) Floor Price (1)
