When the terms defined in Exhibit 1 are used in this Contract, they shall have the meaning ascribed thereto in such exhibit. When the context so requires, the terms defined in Exhibit 1 shall have the same meaning, whether they are used in singular or in plural.

ARTICLE THREE: PURPOSE

3.1 Power Supply

From the Start Date, THE POWER SUPPLIER agrees to supply and make available to THE CUSTOMER at the Points of Delivery, the maximum power (hereinafter, Maximum Power) during Peak Hours and during Off-Peak Hours as established in the following schedule:

		Maximum Power (MW)
				2012
		2011		January 1 to June 30		July 1 to December 31		2013		2014		2015		2016		2017		2018		2019		2020
Peak Hours		16,0		16,0		25,0		34,0		29,5		29,5		36,0		42,0		36,0		44,5		57,5
Off-Peak Hours		24,0		24,0		40,0		50,0		50,0		52,0		52,0		52,0		62,0		65,0		66,0

The Maximum Power values and their application start and end dates anticipated for every year as from 2013, shall be confirmed or modified by the CUSTOMER by written notice forwarded to THE POWER SUPPLIER on a date no later than September 30 — or on the date immediately preceding business day, in case September 30 is a non-business day — of the year immediately preceding in relation to the year corresponding to the Maximum Power and the respective start and end dates subject of confirmation or modification. Under no circumstances may the values of the Maximum Power modified by the CUSTOMER exceed 110% (hundred and ten percent) of the initial values established in the schedule for each period.

In absence of such written notice by THE CUSTOMER, or if the notice was received by THE POWER SUPPLIER after the said day and month, the Parties shall consider that the value to apply will be the Maximum Power determined in the schedule and that the application start and end dates of such Maximum Power, will be January 1 and December 31, respectively, of the year fixed in such schedule.

The Maximum Power represents the Maximum Power Supply obligations of THE POWER SUPPLIER to THE CUSTOMER. The Parties agree to establish — in favor of THE CUSTOMER — a tolerance of 5% (five percent) of the Maximum Power being applicable; thus, THE CUSTOMER may

eventually consume power quantities in excess of the Maximum Power, up to a maximum limit of 5% (five percent) of the applicable Maximum Power, without paying any power excess penalty established in Sub-clause 5.2. This tolerance limit shall be applicable only whenever the power supply to THE CUSTOMER — at the Point of Delivery established in Article Seven — is not shared by THE POWER SUPPLIER with some other supplier.

As from the Start Date, THE CUSTOMER agrees to purchase the Minimum Power (hereinafter, Minimum Power) during Peak Hours and during Off-Peak Hours, and to pay the power charges agreed in Sub-clause 6.2.2. For the purposes hereof, the values of the Minimum Powers are equivalent to 30% (thirty percent) of the respective values of the applicable Maximum Power; this value, with respect to the Maximum Power of the schedule mentioned above, is as follows:

		Minimum Power (MW)
				2012
		2011		January 1 to June 30		July 1 to December 31		2013		2014		2015		2016		2017		2018		2019		2020
Peak Hours and Off-Peak Hours		4,8		4,8		7,5		10,2		8,9		8,9		10,8		12,6		10,8		13,4		17,3

The Minimum Power represents the minimum power purchase obligations of THE CUSTOMER from THE POWER SUPPLIER.

Without prejudice to any increased to the previously prescribed Maximum Power, in case THE CUSTOMER requires increases in the Maximum Power, it may request the additional supply from THE POWER SUPPLIER, in writing, no less than sixty (60) days in advance. In that case, the Parties shall establish the conditions applicable to such increases by mutual agreement.

3.2 Energy Supply

As from the Start Date, THE POWER SUPPLIER agrees to provide on a monthly basis to THE CUSTOMER, at each of the Points of Delivery, the Maximum Power.

As from the Start Date, THE CUSTOMER agrees to purchase and pay on a monthly basis to THE POWER SUPPLIER, the charge for Active Energy agreed in Sub-clause 6.2.4; and, when applicable, the charge for Reactive Energy agreed in Sub-clause 6.4.

3.3 Excess Consumption

THE POWER SUPPLIER shall not be obliged to supply at the Points of Delivery more power than the Maximum Power established in Sub-clause 3.1, or more energy than the Maximum Power established in Sub-clause 3.2.

In case that (i) during more then two (2) consecutive months, or more then three (3) non-consecutive months during the course of a calendar year, the Monthly Maximum Demand During Peak Hours of THE CUSTOMER exceeds the respective Maximum Power plus the tolerance agreed upon in Sub-clause 3.1, where applicable, or (ii) the Active Energy consumption of THE CUSTOMER exceeds the Maximum Power During Peak Hours and/or the Maximum Power During Off-Peak Hours for more than two (2) consecutive months, or for more then three (3) non-consecutive months during the course of a calendar year — without prejudice to the penalties charges agreed upon in Sub-clauses 5.2 and 5.3 — THE POWER SUPPLIER shall notify THE CUSTOMER in writing about such cases of non-compliance. In such cases, if the Parties do not agree to increase the respective Maximum Power, THE CUSTOMER shall be obliged to enter into contracts with other suppliers for the additional power supply in sufficient amount to cater to such excess.

3.4 Modification to the Power under Contract

Only by agreement of the Parties, pursuant to Sub-clause 18.1 may the maximum and minimum power commitments set out in Sub-clause 3.1 be expanded or reduced.

The Parties agree that the supply subject matter of the Contract is of an exclusive nature. Without prejudice to the above, THE CUSTOMER may enter into contracts with other suppliers for its power and energy requirements in addition to the maximum commitments of Power Supply and of energy set out in Sub-clauses 3.1 and 3.2, respectively, only whenever: (i) THE CUSTOMER had entered into a contract with another supplier for part of its power supply requirements on a date prior to that of the signing of this Contract; or, (ii) the Parties had not reached agreement as to the increase of power requested by the CUSTOMER within thirty (30) calendar days following the filing of the request by the latter to THE POWER SUPPLIER, pursuant to the provisions of Sub-clause 3.1. In this case, THE CUSTOMER may enter into contracts with other suppliers for the difference between its total power requirement and the Maximum Power under contract with THE POWER SUPPLIER, invalidating the tolerance of consumer power established in 3.1.

To the extent the power supply of THE CUSTOMER provided by Kallpa Generation S.A., as referred to in Sub-clause 1.2 of Article One, is in effect, that is to say, up to June 30, 2012, the Monthly Maximum Demand of THE CUSTOMER shall be divided between all the electricity suppliers of THE CUSTOMER based on its maximum power under contract or agreed upon, so that the portion corresponding to THE POWER SUPPLIER will be

proportional to the Maximum Power fixed in Sub-clause 3.1 with respect to the total maximum power under contract or agreed upon. In the same case mentioned above, THE POWER SUPPLIER shall assume the part of the total energy consumed monthly by the CUSTOMER, in proportion to the Maximum Power established in 3.1 with respect to the corresponding Monthly Maximum Demand of THE CUSTOMER.

ARTICLE FOUR: TERM

This Contract shall come into force on the date of signing by the representatives of both parties; and it shall end on December 31, 2020.

Without prejudice to the provisions of this clause concerning the term of the Contract, the power supply subject matter of this Contract shall begin on the Start Date defined in Item 14 of Exhibit 1.

ARTICLE FIVE: PRICES, PENALTIES AND ADJUSTMENTS

5.1 For the supply subject matter of the Contract, THE CUSTOMER shall pay monthly to THE POWER SUPPLIER the unit prices set out in Exhibit 2 for the power and for the Active Energy, without prejudice to the provisions of 6.2.7.

5.2 In case that the Monthly Coincident Demand of THE CUSTOMER exceeds the sum of the corresponding Maximum Power plus the consumer power tolerance established in 3.1, where applicable, this excess shall be paid by the CUSTOMER with a penalty; to that effect, THE POWER SUPPLIER shall xxxx and THE CUSTOMER shall pay the price of power set forth in Exhibit 2, plus a penalty of 25% (twenty-five percent) of this price.

5.3 In case that in the Peak Hour period or in the Off-Peak Hour period, the Monthly Maximum Demand During Peak Hours and/or the Monthly Maximum Demand During Off-Peak Hours exceeds the sum of the corresponding Maximum Power plus the consumer power tolerance established in 3.1, where applicable; and, as a result thereof, the monthly power consumption by THE CUSTOMER exceeds the Maximum Power During Peak Hours and/or the Maximum Power During Off-Peak Hours, such excess shall be billed by THE POWER SUPPLIER and paid by THE CUSTOMER as per the penalty equivalent to the portion proportional to such excess of energy of the Cost of Uninstalling Active Energy defined in Item 3 of Exhibit 1, plus 1,7% (one point seven percent).

For purposes of the billing of the penalty for such excess energy, the Cost of Uninstalling Active Energy stated in Nuevos Soles (S/.) shall be converted into US Dollars (US$) with application of the respective weighted average sell exchange rate in effect on the last business day of the supply month published by the Superintendency of Banking, Insurance and Private Pension Fund Management Companies or by the substituting competent body.

5.4 Since it is foreseeable that during the performance of the Contract, THE POWER SUPPLIER may sell power and energy to third parties at a price higher than that agreed to with THE CUSTOMER, or that THE CUSTOMER may purchase power and energy from other suppliers at a price lower than that agreed to in the Contract, the Parties hereby declare that they expressly assume such risks, as risks inherent to the Contract, and that since these assumptions are foreseeable, there shall not be file any claims concerning the modification of the agreed prices or the agreed adjustment formulas, for any reason whatsoever, it being understood that they reciprocally waive to any such claims.

5.5 The prices and penalties agreed to are net, that is to say, they do not include Value Added Tax (VAT) or the Contribution set forth in Law 28749, Item h)  — Rural Electrification Law, that shall be in the account of THE CUSTOMER. In addition, all future changes to the tax laws, which may establish taxes to be paid by electricity consumers, which must be passed on to THE CUSTOMER, shall result in an automatic adjustment to the agreed prices, in such manner that THE POWER SUPPLIER will always receive the agreed upon net prices.
