 This agreement shall have
a mandatory one-year term for both parties, which shall start on May 16, 2005 and shall expire, without fail, on May 15, 2006, without any need for notification, nor prior notice. Nevertheless, thirty (30) days prior to the
termination of the mandatory term, the parties, by mutual consent, may renew the agreement by entering into a new agreement bearing their pertinent signatures authenticated by a notary public.

 The parties hereto agree that the monthly rent stipulated freely and by mutual consent between them, shall amount to US$1,300 (One Thousand

 Page    2 
  

 THE LESSOR hereby undertakes to hand over to THE LESSEE the receipt evidencing the rental payment within
the three (3) days following the date indicated in the tax schedule of the National Superintendency of Tax Administration (SUNAT) and once the pertinent collection has been made. 
  
 Pursuant to the provisions set forth in Article 1697 of the Civil Code, it is hereby agreed that the Agreement shall be automatically
terminated, in the event that THE LESSEE fails to pay the rent of the previous month and the rent of the following month also expires plus fifteen (15) days more, without prejudice to the enforcement action for rent collection, which may
be brought immediately after a default in the payment of the rent of one month. 
  
 FOUR: 
  
 THE LESSEE represents that he knows the
property referred to in Article 1 and he takes possession of the same, to its full satisfaction, with its electric power wiring, water and sewerage facilities, sanitary fittings without cracks and with their taps, doors with locks, windows with
their intact glasses, parquet flooring, ceramics and other furniture and household goods detailed in the attached Inventory, all of them being second-handed. Being the full possession taking enough proof of the acceptance of the above referred
conditions and good functioning; THE LESSEE is therefore, obliged to conscientiously upkeep them and to return them in the same conditions as received, both internally and externally, as well as the gardens, upon termination of the Agreement,
except for the normal wear and tear. 
  
 All repairs and/or replacements that may
be deemed necessary to be effected in said facilities, furniture, household goods and patching, as from the date on which possession of the property is taken, shall be on the exclusive account of THE LESSEE, except for those that may occur
due to faults in the structure, hidden defects or end of the useful life of materials. THE LESSOR reserves the right to visit the leased property, prior appointment with THE LESSEE, which shall be made within a term not to exceed seven
(7) days as from the date of the appointment. 
  
 FIVE:

  
 THE LESSEE agrees to use the property, subject matter hereof,
partly as administrative offices and partly for living purposes, pursuant to the municipal regulations in effect regarding the current characteristics of the property, and not for other purposes, taking the necessary steps, on its own account and
cost, in order to obtain the operating license, as well as those documents which may be required before the pertinent entities, and satisfying, directly and also on its own account, the requirements that may be imposed on it.

also strictly prohibited; any attempts to do so shall be rendered null and void and THE LESSOR would have to pay a compensation for the damages and losses caused. 

  

	b)	Do not make any modification of any kind whatsoever in the leased property; those which are necessary shall require the prior written consent of THE LESSOR. The modifications

necessary facilities for that purpose. 

  

	f)	To adopt all the safety measures that the care and maintenance of the property under his responsibility require for the prevention of any and all risks, damages or losses that may
be derived from its use. 

  
 SEVEN: 
  
 THE LESSOR represents that, upon execution of this Agreement, he has received from
THE LESSEE the amount of US$3,900 (Three Thousand Nine Hundred US Dollars) as a SECURITY DEPOSIT, to back the fulfillment by THE LESSEE of the 

 Page    4 
  

 
obligations undertaken hereunder. It is hereby established that the relevant proportional amounts shall be deducted from the SECURITY DEPOSIT, in the
event that repairs would have to be made in the property or for the payment of the charges that were not paid on time by THE LESSEE, and shall form part of the compensation to be paid in the event that THE LESSOR has to initiate a
summary eviction proceeding, due to the delay in returning the property to THE LESSOR upon termination of this Agreement. 
  
 The aforementioned SECURITY DEPOSIT shall not accrue interest and, for any reason whatsoever and under no circumstances, shall it be considered as a partial or
total payment of the lease. The pertinent part of the SECURITY DEPOSIT shall be returned to THE LESSEE in the same currency (US Dollars) once THE LESSEE has handed over the property vacant, with an inventory of the goods, and
the respective keys to THE LESSOR and THE LESSEE complies with delivering: 
  

	 	•	 	The entire property, the gardens and an inventory of the goods in good conditions.

PROPERTY IS RETURNED. 

  
 EIGHT: 
  
 If THE LESSEE returns the property or terminates THIS AGREEMENT before expiry of the
term hereof, THE LESSEE shall pay THE LESSOR, as LOST OF PROFITS, an amount equivalent to two (2) months of rent. It is hereby placed on record that the property leased includes the telephone line 223-0339 and the device,

entries of the property to THE LESSEE upon execution of this Agreement, and without any evidence other than the signatures of the parties affixed at the end of this document and authenticated by a notary public. 
  
 TEN:

	Attn:	Mr. Fernando Garcia A. 

	    	Vice President and General Manager 

  
 Dear Mr. Garcia, 
  
 Peru Copper is pleased to award SNC-Lavalin the Pre-Feasibility Study for the Toromocho Copper Project, in accordance with your Proposal No. 401-4200 of July 2005. 
  
 As we have stressed in our discussions with you, it is critical that this study is finished
no later than November 30, 2005. As added incentive to complete the study on time, or earlier, we will award an incentive of 20% of total reimbursable costs if the study is delivered by October 30, 2005, and an incentive of 10% of total
reimbursable costs if the study is delivered by November 15, 2005. 
  
 We
look forward to working with SNC-Lavalin on this exciting project, and thank you for your continued interest in Peru Copper. 
  

	
	 Yours truly,

	
	 /s/ Charles G. Preble

	 President and General Manager
