       FINANCIAL STATEMENTS
       DECEMBER 31, 1993
       REPORT OF INDEPENDENT ACCOUNTANTS
       
       April 5, 1994
       
       To the Stockholders and Directors
       Empresa Minera Especial Tintaya S.A.
       
       1.       We have examined the balance sheet of Empresa Minera
                Especial Tintaya S.A. as of December 31, 1993, and the
                related statements of income, of changes in
                stockholders' equity and of cash flows for the year
                then ended, as expressed in new Peruvian soles.  These
                financial statements are the responsibility of the
                Company's management.  Our responsibility is to express
                an opinion on these financial statements based on our
                audit.
       
       2.       We conducted our audit in accordance with auditing
                standards generally accepted in Peru, which are
                substantially the same as those followed in the United
                States of America.  Those standards require that we
                plan and perform the audit to obtain reasonable
                assurance about whether the financial statements are
                free of material misstatement.  An audit includes
                examining, on a test basis, evidence supporting the
                amounts and disclosures in the financial statements. 
                An audit also includes assessing the accounting
                principles used and significant estimates made by
                management, as well as evaluating the overall financial
                statement presentation.  We believe that our audit
                provides a reasonable basis for our opinion.
       
       3.       The restatement of  these financial statements to
                reflect changes of the purchasing power of the new
                Peruvian sol, as explained in Note 3, is generally
                accepted in Peru.  Although accounting principles
                generally accepted in the United States of America do
                not address financial reporting as a separate entity in
                local currency financial statements of a company in a
                highly inflationary country, under the severe and
                prolonged inflationary conditions that prevailed in
                Peru we regard the recording of these price-level
                values as appropriate.
       
       4.       In our opinion, the financial statements audited by us
                present fairly, in all material respects, the financial
                position of Empresa Minera Especial Tintaya S.A. at
                December 31, 1993 and the results of its operations and
                its cash flows for the year then ended, in conformity
                with accounting principles generally accepted in Peru.
       
       5.       As described in Note 2 to the financial Statements, the
                Comision Especial de Privatization (CEPRI) of Empresa
                Minera Especial Tintaya S.A. requested from the
                Comision   de   Promocion  de la Inversion Privada
                (COPRI)an integral solution to the outstanding
                receivables and debts and contingencies that the
                Company maintains with Government entities and the Bank
                Syndicate referred to in Note 10.  As of the date of
                this report the issue of the corresponding legal
                disposition for the afore-mentioned solution is still
                pending.  In the event that the integral solution is
                accepted as requested, the Government would capitalize
                its outstanding debt, net of the other obligations and
                the Company would give as definitive payment its cash
                position as of the date of the agreement.
       
       6.       As presented in Note 9, the Company has incurred
                significant pre-operating costs which, in accordance
                with the estimates and projections of management, will
                be recovered from future operations.
       
       7.       Accounting principles generally accepted in Peru vary
                in certain significant aspects from principles
                generally accepted in the United States.  Application
                of accounting principles generally accepted in the
                United States would have affected the determination of
                results of operations for the year ended December 31,
                1993 and total stockholders' equity at December 31,
                1993 to the extent summarized in Note 19 to the
                financial statements.
       
       8.       The U.S. dollar amounts are presented solely for the
                convenience of the reader and in our opinion have been
                translated in accordance with the basis described in
                Note 3-g.  This translation should not be construed as
                representing that the new Peruvian Sol amounts actually
                represent or have been, or could be, converted into
                U.S. dollars.

EMPRESA MINERA ESPECIAL TINTAYA S.A.


NOTES TO THE FINANCIAL STATEMENTS
DECEMBER 31, 1993


1    OPERATIONS

Empresa Minera Especial Tintaya S.A., owned by three state-owned agencies,
was incorporated on May 2, 1980 as Empresa Minera Asociada Tintaya S.A.
(EMATINSA).  In order to comply with Decree Law 109, General Mining Law, on
August 26, 1981 EMATINSA was transformed into Empresa Minera Especial Tintaya
S.A. through Supreme Decree 023-81-EM-VH.

The Company's operations are related to the exploration of ore deposits and
production of copper concentrates in deposits located in the province of
Espinar in Cusco.

The Company activities are regulated by the Government Business Activity Law,
its Organic law and the Mining and General Business laws in everything that
is not related to the Government Business Activity Law.  The Company is
supervised by the Corporacion Nacional de Desarrollo - CONADE and the
Contraloria General de la Republica.

2    PRIVATIZATION PROCESS

On September 25, 1991, the Government issued Legislative Decree 674 "Ley de
Promocion de la Inversion Privada en las Empresas del Estado", which
regulates, inter-alia, the mechanism to promote investments and creates the
Comision de Promocion de la Inversion Privada (COPRI), which is in charge of
designing and managing the process.

On February 13, 1993 the Government included the Company under the
regulations of Decree Law 674, and appointed a special privatization
commission (CEPRI) for this purpose.

On December 28, 1993, CEPRI - TINTAYA requested from COPRI an agreement with
the Public sector for an integral solution of the liabilities, debts and
claims against TINTAYA, in order to facilitate the privatization process.

The support of the COPRI has been requested in order to:
- -   Reconcile balances and define the contingencies pending between TINTAYA
    and other Government entities (Note 15).

- -   Obtain the acceptance by the Bank Syndicate of the assumption by the
    Peruvian Government of the Company's outstanding debt (Notes 10 and 15).

- -   Obtain the issuance of a Supreme Decree by which the Peruvian Government
    will assume the Company's debt including the tax contingencies in
    exchange for approximately US$62,000,000 which will comprise of cash and
    other Government debt to be obtained at the date of issuance of the
    above-mentioned Supreme Decree.

3   SIGNIFICANT ACCOUNTING POLICIES

The most significant accounting policies used in the preparation of the
financial statements are as follows:

a)  Generally accepted accounting principles in Peru require the restatement
    of the financial statements to reflect the changes in the purchasing
    power of the Peruvian currency.  The methodology for the restatement of
    the financial statements corresponds substantially to that approved by
    Resolutions 2 and 3 of the Consejo Normativo de Contabilidad, as
    follows:

    i)   The adjusted balances correspond to the historical values that have
         been restated to express them in currency of the year-end
         purchasing power, by applying the coefficients obtained from the
         Wholesale Price Index (index issued by the Instituto Nacional de
         Estadistica e Informatica - INEI).

    ii)  Non-monetary items, such as inventories, property, plant and
         equipment, intangibles and stockholders' equity, have been restated
         applying the index from the date of origin of the component parts. 
         In all applicable cases, the lower of cost or market value criteria
         has been maintained.  

         Profit and loss accounts, except for depreciation of property,
         plant and equipment, amortization of intangibles and cost of sales,
         which were determined on the adjusted value of the corresponding
         assets, have been adjusted by applying to the monthly historical
         balances the indexes corresponding to such months.

         The January 1, 1993 balance of the Statement of Stockholders'
         Equity have been restated in the currency of December 31, 1993 by
         applying the corresponding inflation rate of the year as described
         in note 3 a)ii).  In the case of the capital account, the Company
         has to issue shares in order to support this restatement.

    iii) Monetary items have not been adjusted because their balances at
         historical values correspond to the purchasing power of the
         currency at the end of the year.

    iv)  Non-monetary items in foreign currency have been previously
         translated into  Peruvian currency at the year-end exchange rate.

b)  Sales of minerals and their corresponding costs are included in income
    when realized.

c)  Depreciation is calculated consistently using the straight-line method
    over the estimated useful lives (Note 8).  Maintenance and repair
    expenses  are charged to production costs as incurred and improvements
    and betterments are capitalized.  The cost and related accumulated
    depreciation of assets sold or retired are eliminated from the
    respective accounts and the resulting gains or losses are included in
    the year's income.  The provision for loss in market value resulted from
    the comparison, on an individual basis, of the restated cost of the
    assets with values determined by the technical appraisals performed by
    independent appraisers.

d)  Intangibles (including concessions and mineral rights, exploration and 
    development cost, feasibility studies and, pre-operating cost) are
    included in other assets when incurred and are amortized on a straight-
    line basis over a ten year period from the time they begin to generate
    benefits for the Company.

e)  Employees' severance indemnities are accounted for on an accrual basis. 
    The amount accrued represents the amount owed to employees assuming
    their termination is as of the date of the financial statements, net of
    advances and deposits made, which are considered as definitive payments
    to the employees.  According to current legislation, these payments are
    deposited in restricted savings accounts in financial institutions or
    are maintained within the Company and will be available to the employees
    at the date of their termination.

f)  For the purpose of the preparation of the statement of cash flows,
    deposits in banks and dollar bank certificates with maturity of three
    months or less are considered as cash equivalents.

g)  The financial statement amounts expressed in new Peruvian soles have
    been translated into U.S. dollars for the convenience of the reader at
    the year-end exchange rate of S/.2.16 per US$1.

4   BALANCES IN FOREIGN CURRENCY

                                   ===========    ===========

The debt relates to loans received from the Export Development Corporation of
Canada and a bank syndicate represented by the Toronto Dominion International
Bank, Ltd. and bears annual interest of 3%.  Principal and interest are
payable in semi-annual installments of US$4,449,018 with maturity in the year
2004.  This debt, incurred between 1980 and 1985, is guaranteed by the
Peruvian Government.  As a result of the financial position of Peru and of
the Company, the Government, through Supreme Decree No.061-81-EF as of June,
1989, authorized the Ministry of Economy and Finance to sign a contract with
the Company under which outstanding debt of US$225,000,000  at  December  15, 
1988  was  assumed  by  the  State  as  follows: US$92,000,000 was
capitalized with the Company undertaking to re-acquire the shares over a term
of 7 years (Note 12-a) and the balance of approximately US$ 133,000,000 was
to be repaid in semi-annual installments with due dates until December 15,
2003 and bearing an annual interest of 3%.

On February 28, 1994 the Direccion General de Credito Publico, the
Corporacion Nacional de Desarrollo and TINTAYA agreed to modify the above
described contract.

Main modifications are:

- -    Capitalized debt reduced from US$92 to US$82.4 million.
- -    Rescheduled debt reduced from US$133.6 to US$129 million
- -    The maturity date extended to December 15, 2004.

As from 1989 the Company has amortized US$31,302,018 of the re-financed debt,
expended US$9,575,350 for repurchase of shares as well as US$16,820,228 of
interest.  Additionally, from 1987 to 1989 the Company made payments of
US$44,686,712 and US$7,735,491 corresponding to capital and interest,
respectively.  These amounts have been deposited in a special account of the
Banco de la Nacion.

In order to facilitate an integral solution to the liabilities and debts of
TINTAYA with other Government entities, the Company's Board of Directors
agreed to suspend the payment of the second installment due on December 15,
1993. 

11   MINING LAW

a)   In October 1991 Legislative Decree No.677 was issued, establishing a
     new basis to calculate the workers' participation as from 1992.  The
     most significant aspects of this legislation are as follows:

            i)    The workers' participation in the Company's earnings will
                  be 8% of taxable income.  This participation is deductible
                  for income tax purposes.

            ii)   Workers will participate in the administration of the
                  Company through special committees aimed to increase
                  production and productivity.  The workers will no longer
                  have a representation on the Board of Directors and the
                  mining communities can be voluntarily dissolved.

            iii)  In the event of a capital increase through a public stock
                  offering, the Company should offer to the workers a
                  preferential option to purchase at least 10% of the
                  capital increase.

b)   In May 1993 the Government issued Supreme Decree 016-93-EM regulating
     Article 15 of the General Mining Law in connection with environmental
     protection as a consequence of mining activities.  In accordance with
     this legislation, mining companies should present to the Ministerio de
     Energia y Minas an annual report that should include detailed
     information about air pollution and spills of tailings.  In addition,
     mining companies should prepare an environmental management program -
     PAMA in order to reduce the levels of environmental pollution.  This
     report should be signed by an environmental auditor.  Management
     considers that this program is in compliance with environmental
     legislation.


12   STOCKHOLDERS' EQUITY

a)   Capital

The authorized and subscribed capital stock at December 31, 1993 is
represented by 1,409,499 common shares of 250 intis each (one new Peruvian
sol equals one million intis).

As of December 31, 1993 the Company has not yet issued 1,724,000 shares
related to the capital restatements for the years 1990 to 1993 in new
Peruvian soles.  (See note 3a)ii)).  In accordance with current legislation,
the issuance of these shares is not considered as dividends and is exempt
from income taxes.  The issuance of shares does not have an impact on
stockholders' equity or the Company's operations.

On June 30, 1989 the Company capitalized US$92,000,000 related to the
Company's debt assumed by the Peruvian Government (Note 10).  In 1990 the
Company  repurchased shares amounting to US$9,575,350, thus, according to the
modification included in the contract suscribed with the Peruvian Government
in 1994, the new capitalized debt amounts to US$82,424,650.  No shares were
repurchased during 1993.

b) Capital surplus

In 1992 the Peruvian Government made capital contributions in accordance with
Supreme Decree 107-91-EF through the capitalization of 60% of selective sales
taxes related to the purchase of oil and gas.  In 1993 this legal disposition
was revoked.

c)  Accumulated deficit

         i)   In accordance with the Article 11 of the Legislative Decree 627 
              the difference between the restated accumulated losses at
              December 31, 1991 and the corresponding retained earnings at 
              historical values may be off set with the adjustment resulting
              from the restatement of common shares and labor shares.

         ii)  In accordance with clause 7 of the contract subscribed with the
              Peruvian Government, dividends from shares related to the
              capitalization of debt of US$92,000,000 should only be used in the
              repurchase of stock.  In addition, earnings related to the other
              shares should be capitalized until the repurchase of shares is
              completed (Note 10).

13  RESULT OF EXPOSURE TO INFLATION

At December 31, 1993, the monetary position comprised:





                                          S/.             US$

14   TAX SITUATION

a)   On December 28, 1984 the Company subscribed to a tax stability contract
     with the Peruvian Government which provides benefits in order to
     encourage the recoverability of the investment in deposits of Tintaya. 
     The contract is effective from 1986 until the date the Company recovers
     the amount of the investment (sub-clause 7.4).

     In accordance with the terms of the contract a special tax regime for
     the Company was established as follows:

     i)     Reduction in one-third of the amount of the annual income tax
            payable.  The contract provides the Company with an additional
            period  (sub-clause 8.6) after the date when the Company
            recovers the amount invested. 

     ii)    Exemption from equity taxes in accordance with Article 29 of
            Law 24030.

     iii)   Continued application of the tax legislation and rates effective
            as of December 28, 1984. 

     iv)    Possibility to apply a global depreciation rate of 20% on
            property, plant and equipment without prior approval from the
            tax authorities.

     v)     No restrictions on sales abroad and on the corresponding foreign
            currency obtained from such sales; however, the Company should
            previously sell its production locally in order to satisfy local
            demand.

     vi)    Possibility of maintaining accounting records in U.S. dollars
            for tax purposes.  At present, the Company maintains separate
            accounting records in U.S. dollars and in new Peruvian soles.

b)   The Company is not liable for income tax due to an accrued taxable loss
     which was determined following the regulations established at December
     28, 1984.  Such loss amounts to US$1,822,680 and will be deductible
     from net taxable income generated for the next four years as from 1993.

            Because the Company does not have taxable income, it was not
            obliged to pay participations to its workers.

c)   The years 1990 to 1993 are open to examination by the tax authorities. 
     Management considers that no significant liabilities will arise from
     these reviews.  The years 1987 to 1989 have been reviewed by the tax
     authorities.  Possible final assessments in this respect are still
     pending.

d)   In 1992 the Company filed for the "Beneficio Especial de Regularizacion
     Tributaria" (BERT) in order to regularize income tax payments for the
     years 1989, 1990 and 1992.

15   CONTINGENCIES

a)   In 1990 the Export Development Corporation of Canada, the Bank of Nova
     Scotia and eighteen banks filed a claim for the non-payment of loans. 
     The claims are related to the payment of US$148,091,851 and
     US$185,091,884, respectively, and the corresponding interest.  In
     accordance with the agreement signed with the Club of Paris, a group
     comprising major creditors  of  Peru, on  September 17, 1991, the
     Peruvian Government  renegotiated  the  debt  with the  Export 
     Development Corporation. Negotiations between the  Peruvian  Government 
     and  the  commercial banks are currently in process.  Management
     considers that no significant liabilities will arise as a consequence
     of these lawsuits, because of the agreement with the Government as
     explained in Note 10.

b)   As of December 31, 1993 the Company received additional tax assessments
     for approximately US$26,388,000 related to unpaid additional sales
     taxes during 1987 and 1989.  According to the tax stability contract
     suscribed with the Peruvian Government mentioned in Note 13, the
     Company is exempted from this additional tax, and the assessments are
     considered invalid.  Additionally, as explained in Note 2, these
     contingencies will be included in the debt reconciliation process which
     is being negotiated with the Peruvian Government.

17.   OTHER MATTERS                         

a)   In accordance with clause 10.2 of the original Contract of Financial
     Restructuring, TINTAYA is prevented from merging or consolidating with
     another entity or selling, transfering or passing in whatever fashion
     its properties.  The CEPRI is taking steps to obtain the necessary
     legal dispositions to remove this clause.

b)   In December 1993, it was agreed to constitute the Empresa de Generacion
     Electrica del Sur S.A. - EGESSA with the only shareholder  being
     TINTAYA in  order  to  develop the generation of electricity.  In
     January 1994, the Thermoelectric Plant of TINTAYA was transferred to
     EGESSA at its market value of US$13,550,000 which approximates to its
     carrying amount.

18.  SUBSEQUENT EVENTS

a)   On February 4, 1994, the General Administration of Mining approved a
     reinvestment program under which the Company could reinvest
     US$7,220,000 to maximize its operations.  In accordance with the
     current tax stability contract, TINTAYA can appropriate 40% of income
     before tax to such reinvestments which are tax deductible.

b)   On March 18, 1994, Supreme Decree 016-94-PCM was issued authorizing
     TINTAYA to carry out a downsizing program to terminate its personnel. 

19.  SIGNIFICANT DIFFERENCES BETWEEN PERUVIAN AND UNITED STATES GENERALLY
     ACCEPTED ACCOUNTING PRINCIPLES

The financial statements of the Company are presented on the basis of
accounting principles generally accepted in Peru (Peruvian GAAP) and have
been expressed into U.S. dollars in accordance with the basis described in
Note 3-g).  Peruvian GAAP are in general terms similar to the accounting
principles generally accepted in the United States (US GAAP).  However, there
are areas in which Peruvian accounting standards and practices differ from
the requirements of US GAAP and Magma Copper Company s accounting policies.

Significant differences between Peruvian GAAP and US GAAP are as follow:

a)   Recognition of the effects of inflation on financial information

The reconciliation to US GAAP shown below does not include the reversal of
the adjustment to the financial statements for the effects of inflation
required under Peruvian GAAP, because the application of inflation accounting
represents a comprehensive measure of the effects of price level changes in
the hyperinflationary  Peruvian economy and, as such is considered a more
meaningful presentation than historical cost-based financial reporting for
both Peruvian and US accounting purposes.

b)   Mineral exploration costs

Following Peruvian GAAP, the Company exploration and development costs of new
deposits are capitalized and amortized over a ten year period as from the
date they begin  to generate benefits to the Company.  US GAAP require these
costs to be charged to expense when incurred unless feasibility is proven. 
In addition, amortization under US GAAP is based on units of production.

c)   Accounting for the lower of cost or market value of materials and
     supplies inventory

In accordance with Peruvian GAAP the Company performed the comparison for the
lower of cost or market value of materials and supplies on an aggregate
basis.  US GAAP requires that the rule of cost or market, whichever is lower,
should be applied directly to each item or to the total components of each
major category.

d)   Maintenance and repair expenses

In accordance with Peruvian GAAP, significant maintenance and repair costs
are deferred in accordance with the estimated duration of the repair. In
accordance with US GAAP significant maintenance and repair expenses are
generally charged to expenses as incurred.

e)   Metals inventory

Under Peruvian GAAP, all production costs incurred are included in inventory
costs.  In accordance with US GAAP the measurement point for copper begins
only after initial processing of ore.

(f)   Income tax

Under Peruvian GAAP, income tax is recognized on the basis of amounts due in
accordance with Peruvian tax regulation.  US GAAP requires that deferred tax
liabilities and assets be recorded for the expected future tax consequences
of events that have been included in the financial statements or tax returns. 
Under this method, deferred tax liabilities and assets are determined based
on the difference between the financial statements and tax bases of assets
and liabilities using current tax rates in effect for the year in which the
differences are expected to reverse.

(g)   Summary of income statement and stockholders' equity differences

Following is a reconciliation of net income and stockholders' equity that
would have been required if the Company had applied US GAAP instead of
Peruvian GAAP.

(h)   Income tax calculation

Under Peruvian GAAP, income tax is recognized on the basis of amounts due in
accordance with Peruvian tax regulation.  For US GAAP purposes, the Company
has adopted the provisiones of FAS 109 "Accounting for Income Taxes".

FAS 109 requires recognition of deferred tax liabilities and assets for the
expected future tax consequences of events that have been included in the
financial statements or tax returns.  Under this method, deferred tax
liabilities and assets are determined based on the difference between the
financial statements and tax bases of assets and liabilities, using current
tax rates in effect for the year in which the differences are expected to
reverse.

Deferred income tax has been calculated as follows:

(j) Disclosure on environmental issues

Based on an environmental review by a third party the only immediate
environmental issue relates to small clean-up of fuel and chemical storage
facilities.  It is estimated that the cost for this clean-up will be in the
range of US$150,000 to US$250,000.  This amount does not address any
reclamation issues which Management considers not significant.

been effective as of the beginning of the period.  The acquisition will be
accounted for as a purchase.  The pro forma adjustments are based upon the
estimated fair value of the assets and liabilities of Tintaya as of
September 30, 1994, and are based on preliminary estimates, evaluations and
other data which are currently available and may change as a result of
further analysis.

     The Pro Forma Statements of Income are not necessarily indicative of
the actual results which would have occurred had the acquisition been
consummated at the beginning of such period or of future consolidated
operations of the Company.  The pro forma financial information has been
prepared by the Company and all calculations have been made by the Company
based upon assumptions deemed appropriate by the Company.  Certain of these
assumptions are set forth under the Notes to the Unaudited Pro Forma
Consolidated Financial Statements.  These statements should be read in
conjunction with the historical consolidated financial statements and the
notes thereto of the Company included in the Company's latest annual report
on Form 10-K, The Company's latest quarterly report on Form 10-Q and the
historical financial statements and the notes thereto of Tintaya filed with
this Form 8-K/A-1.

 and conditions:
 <PAGE>
 ARTICLE ONE:  HISTORICAL BACKGROUND
 
 1.1  Supreme Decree No. 014-71-EM/DGM dated September 27, 1971
 created the Special Right of the State over the TINTAYA Economic
 and Administrative Unit which comprises the field of expired
 Mining Concessions, a list of which is attached as Enclosure I of
 this Agreement, located in the District of Yauri, Espinar
 Province, Department and Jurisdiction of the Regional Mining
 Directorate at Cusco, at an average elevation of 4,100 meters and
 at a distance of 250 km by road from the city of Cusco via Urcos,
 Yanaoca and Yauri as shown in the enclosed plan which forms an
 integral part of this Agreement as Enclosure II.
 
 Under the same Supreme Decree, said Special Right of the State
 was assigned to Empresa Minera del Peru (hereafter called MINERO
 PERU), commissioning the latter in accordance with Article 2 of
 its Constitution   Decree Law No. 18436 repealed by Decree Law
 No. 20035, the latter again repealed by Legislative Decree No.
 42, Minero Peru's current Constitution   to operate the
 State-owned Mining Industry in its behalf. To permit [Minero
 Peru] to exercise its mining activities, Article 3 of said
 current Constitution, as did its earlier Constitutions, defers to
 the General Mining Law, then known as Decree Law No. 18880 which,
 as does the current General Mining Law approved by Legislative
 Decree No. 109, empowers holders of the Special Right of the
 State to make use of said right in the manner regulated therein,
 thus allowing for the assignment of exploration and/or mining
 rights on the basis of the Special Rights of the State under both
 these laws.
 
 1.2  Since its creation, Minero Peru has taken part in the
 formation and administration of the Empresas Estatales Mineras
 Asociadas and the Empresas Mineras Especiales, as a result of
 which it was converted into the Empresa Estatal Minera Asociada
 <PAGE>
 Tintaya Sociedad Anonima   EMATINSA  , to which it assigned the
 usufruct of the aforementioned Special Right of the State, i.e.
 the right to perform exploration and mining operations, for the
 duration of its existence and in partial payment of its share in
 the corporate capital. This usufruct also included the actual
 work performed and the data obtained therefrom, as well as
 feasibility and basic engineering studies performed until then.
 This contribution remained unchanged when, in accordance with
 Temporary Provision Sixteen of the new General Mining Law,
 Legislative Decree No. 109, EMATINSA became a Special Mining Firm
 but continued to be a Sociedad Anonima.
 
 The latter is the current corporate form of the Government in
 accordance with Supreme Decree No. 023-81EM/VM dated August 26,
 1981. By virtue of the aforementioned contribution in kind and
 without prejudice to Minero Peru's ownership to same, the
 Corporation holds title to the mining activities under the
 Special Right of the State.
 
 1.3  By Letter No. GF-0141 dated November 12, 1981 citing the
 provisions of Article 52 of the current General Mining Law
 supported by Articles 157 and 159 of the same body of law, the
 Corporation petitioned the Ministry of Energy and Mining to grant
 it a contract providing the benefits and guarantees contained in
 the aforementioned Articles, to allow it to initiate mining
 operations at the Tintaya Economic and Administrative Unit
 (hereafter referred to as the TINTAYA PROJECT) under the Special
 Right of the State.
 
 1.4  Under Supreme Decree No. 027-84-EM/VM dated August 24, 1984,
 the Regulation to the Articles referred to under 1.3, above, of
 the General Mining Law was approved. In its Temporary Provision
 Two, this Regulation sets forth that titleholders of Mining
 Operations may apply for the benefits offered under the 
 <PAGE>
 aforementioned Article 157 for any project for which a permit was
 requested between the time Legislative Decree No. 109 took effect
 and the publication date of the aforementioned Regulatory Supreme
 Decree, and which was started during the aforementioned period,
 as was the case with the Corporation. The said Regulation also
 establishes that the work performed and/or the investments
 effected during the said period shall be credited to the
 computation of recoverable investments referred to in Article 159
 of the Law, provided the activities funded by such investments
 were approved in accordance with the abovementioned Regulation.
 
 1.5  In view of the foregoing information and based on the
 explanations provided in the following Article, the Government,
 upon the signing of this Agreement and duly approved under
 Supreme Decree No. 044-84-EM/OGAJ, grants [the Corporation] the
 benefits and guarantees provided by Article 157 of Legislative
 Decree No. 109 for the term indicated in Article 159 of the said
 legal body. 
 
 ARTICLE TWO:  BASIC ASPECTS OF THE AGREEMENT.
 
 The reasons on the basis of which the Government grants and signs
 this Agreement with the Corporation are the following:
 
 2.1  The project is a new mining operation of justifiable
 financial proportions;
 
 2.2  The startup of the Tintaya Project is part of the National
 Plan to Develop the Mine Production of the Country;
 
 2.3  Within approximately fourteen years of operation at a
 production rate of 8,000 metric tons per day of copper sulfide
 ore, the Tintaya Project will produce a positive net influx of
 foreign currency beneficial to the country's trade balance and
 its balance of payments;
 
 2.4  From the standpoint of its immediate impact, the startup of
 the Tintaya Project signifies the reactivation of the civil
 construction industry, the design and planning branch, and
 engineering supervision activities, as well as the creation of
 jobs in each of these industries and/or activities. From the 
 
 <PAGE>
 standpoint of its impact on the region, it means the utilization
 of the unskilled labor pool at Cusco, Punto, Arequipa and Espinar
 Province which will contribute to the development of other
 economic activity in the region.
 
 2.5  From the standpoint of infrastructure, the Tintaya Project
 will combine the development of its own infrastructure with the
 existing one and/or that required for other projects;
 
 2.6  The Corporation has met the requirements for the signing of
 this Agreement set forth by law, and
 
 2.7  The benefits and guarantees the General Mining Law will
 provide will result in the complete amortization of the loans
 obtained for the construction and startup of the Tintaya Project
 within the agreed terms.
 
 ARTICLE THREE:  MINING RIGHTS.
 
 As set forth in Article 1.3, the Tintaya Project is subject to
 the Special Right of the State as established under Supreme
 Decree No. 014-71-EM/DGMJ concerning the expired Mining
 Concessions listed in Enclosure I, whose location is shown in
 Enclosure II. For the purposes of this Agreement and in
 accordance with Article 160 of the General Mining Law, this
 Special Right of the State constitutes an Economic and
 Administrative Unit.
 
 The provisions of the preceding paragraph do not prevent the
 Corporation from adding additional mining rights to the Tintaya
 Project, in which case and in the event this addition increases
 the reserves, these additional mining rights shall be added to
 the existing reserves to permit the calculation of the minimum
 production level required by the General Mining Law.
 
 ARTICLE FOUR:  INVESTMENT PLAN AND TIMEFRAME FOR EXECUTION.
 
 4.1  The Investment Plan details all procurement and preparatory
 and construction work required for the project's startup or to
 initiate the production process at the Tintaya Project, and also
 specifies the approximate minimum investment amount needed. This
 
 <PAGE>
 Investment Plan, which was duly authorized by the Government
 prior to the signing of this Instrument, forms an integral part
 of this Agreement as Enclosure III.
 
 
 4.2  The total timeframe for the execution of the Investment Plan
 covers 11 months and shall unfailingly expire on May 31, 1985,
 inasmuch as the Corporation, in accordance with the provisions of
 Article 1.4, began to implement it in January 1982, immediately
 after it filed the required application for the signing of this
 Agreement with the Ministry of Energy and Mining.
 
 In terms of the construction and [other] work already completed,
 this work is already included in the Investment Plan at the
 amounts that were actually invested. However, should it prove
 necessary to effect changes, they may be made both in terms of
 work already executed and in regard to uncompleted work, provided
 the final objectives of the Investment Plan remain unaffected,
 and provided also that in both such cases, the Corporation has
 previously filed an application with the Directorate General of
 Mines to secure approval of such changes and/or expansions,
 without prejudice to the express or tacit approval by the
 aforementioned Directorate General so that any changes and/or
 expansions effected may be revalidated and included in the
 Investment Plan.
 
 4.3  Among the principal efforts contained in the Investment Plan
 are the following:
 
      4.3.1     In terms of the road system, the installation of a
 road network by upgrading the existing and building new roads to
 permit the transport of materials and supplies to the Tintaya
 Project site, including an airport.
 
      4.3.2     Removal of approximately 20 million tons of barren
 rock and other materials to permit the startup of mining
 operations.
 
      4.3.3     Construction of a metallurgical ore flotation
 plant with a capacity to treat 8,000 metric tons per day.
 <PAGE>
      4.3.4     Construction and installation of a thermal power
 plant with a generating capacity of 16.5 MW, sufficient to meet
 the electric power needs of the mining operations as well as any
 additional industrial facilities and residential quarters to
 develop and operate the Tintaya Project.
 
      4.3.5     Construction of urban centers necessary to house
 the workers employed at the Tintaya Project. The buildings will
 meet current standards of housing, education and medical care.
 
      4.3.6     Opening an office of Industrial Relations to
 permit the Corporation to comply with legal standards regarding
 safety and hygiene and to train its workers by means of suitable
 and efficient activites and services.
 
      4.3.7     The installation and operation of private
 telephone and/or radio-telephone services subject to applicable
 legal provisions to provide communication services between the
 Tintaya Project site and Arequipa, Mollendo-Matarani, Cusco and
 Lima, as well as the installation of an automated microwave
 station.
 
 4.4  By implementing this Investment Plan, the Corporation hopes
 to reach a production level of approximately 150,000 metric tons
 per year of copper concentrates, with a 50,000 metric ton fine
 copper content during the investment recovery period.
 
  
 ARTICLE FIVE:  AMOUNT TO BE INVESTED IN THE TINTAYA PROJECT AND
 MANNER OF FINANCING.
 
 5.1  The implementation of the Investment Plan, Enclosure III,
 calls for a total investment of approximately US$ 333,500,000.00
 (three hundred and thirty-three million five hundred thousand
 U.S. dollars). This amount comprises the following:
 
 US$ 31,500,000.00 (thirty-one million five hundred thousand U.S.
 dollars), representing Minero Peru's non-financial contribution
 to the corporate capital in the form of the assignation of
 exploration and exploitation rights under the oft-mentioned
 Special Right of the State, including the import of the work
 already performed, as well as the previously obtained data and
 
 <PAGE>
 the feasibility and basic engineering studies up to the formation
 of the Corporation, and which have since been in the latter's
 possession.
 
 US$ 33,000,000.00 (thirty-three million U.S. dollars) to cover
 interest, financial, and legal charges generated by or deriving
 from loans taken during the construction period; and 
 
 US$ 269,000,000.00 (two hundred and sixty-nine million U.S.
 dollars) representing the working capital during the same period.
 
 In accordance with the provisions in paragraph 3 of Article 159
 of the General Mining Law and Articles 36 and 37 of Supreme
 Decree No. 027-84-EM/VH, the final total investment shall be
 established upon completion of the construction work.
 
 5.2  The financing of the Investment Plan at this time is
 complete, as shown in the following:
 
      5.2.1  US$ 100,000,000.00 (one hundred million U.S. dollars)
 from the Corporation's own capital previously paid in and still
 being paid in by its shareholders in accordance with the
 requirements of the Investment Plan and in conformance with the
 provisions of Sub-Articles 5.3, 5.4 and 5.6 of Article Five of
 the Public Document dated May 2, 1980 representing the
 Corporation's Articles of Incorporation and its Bylaws, as
 executed before Lima Notary Dr. Virgilio Alamora Valdez following
 the approval by Supreme Decree No. 013-80-EM/DGM dated March 19,
 1980 of said Articles of Incorporation and Bylaws; and in
 accordance with Decision No. 79/84 adopted by the Corporate Board
 during Board Session No. 17/84 of July 3, 1994.
 
      5.2.2  US$ 215,000,000.00 (two hundred and fifteen million
 U.S. dollars) from loans the Corporation has secured from the
 Canadian Export Development Corporation (US$ 100,000,000.00) (one
 hundred million U.S. dollars) and from the Toronto Dominion
 International Bank Limited as agent of a Banking Syndicate (US$
 115,000,000.00) (one hundred and fifteen million U.S. dollars).
 These loans are guaranteed by the Government. The guarantee and
 the loans were approved by Supreme Decree No. 280-81-EFC dated
 December 7, 1981 following government approval of the terms by
 
 <PAGE>
 Legislative Decree No. 237 and by Decree Laws No. 22959, 23225
 and 23117, of which the first two were amended and the latter was
 repealed by Legislative Decree No. 237.
 
      5.2.3  S/. 28,387,111,865 (twenty-eight billion three
 hundred and eighty-seven million one hundred and eleven thousand
 eight hundred and sixty-five Gold Soles) by way of capital
 contribution and formation of reserves for future capitalization
 compounded against the Import Tax and General Sales Tax payable
 on the importation of capital equipment earmarked for the
 development and operation of the Tintaya Project in accordance
 with the provisions of Legislative Decree No. 159 dated June 12,
 1981, Supreme Decree No. 276-81-EFC of November 27, 1981, as well
 as the unanimous Shareholders Decision No. 08/83 adopted during
 the Extraordinary General Shareholders' Meeting No. 06/83 held on
 December 30, 1983.
 
 
 ARTICLE SIX:  PRODUCTION STARTUP.
 
 6.1  The production startup date shall be the ninetieth day of
 continuous operation of the Tintaya Project at 80% of the rate
 projected in 4.4.
 
 6.2  For the production startup date to be recorded as the
 official date, the Corporation shall make written notification to
 the General Mining Directorate by submitting a sworn statement
 within 30 calendar days following said event.
 
 6.3  It should be noted, however, that the production startup
 date of the Tintaya Project does not constitute the beginning of
 the investment recovery period, which will in fact begin upon the
 conclusion of the Investment Plan following the fiscal year after
 the one in which the total recoverable investment amount under
 the Agreement is determined.
 <PAGE>
 
 ARTICLE SEVEN:  TERMINATION OF INVESTMENT PLAN, AMOUNT OF
 RECOVERABLE INVESTMENTS, AND START OF RECOVERY OF FUNDS INVESTED.
 
 7.1  Within 90 days after the Investment Plan for the Tintaya
 Project is completed, but no later than March 31, 1985, the
 Corporation shall submit the following documentation to the
 General Mining Directorate:
 
      7.1.1  A Sworn Statement reporting the completion of the
 Investment Plan and detailing the work and acquisitions that were
 made, as well as the total amount financed from loans and the
 Corporation's own capital.
 
      7.1.2  Financial Statements as of the date the Project is
 concluded, along with enclosures or comments showing the
 investments and acquisitions, all of which shall be supported by
 reports from independent auditors.
 
      7.1.3  The Corporation shall also grant the General Mining
 Directorate, at the location where it maintains its books, access
 to any documentation that may be necessary to verify the accuracy
 of the information contained in the Sworn Statement.
                                            
 7.2  The General Mining Directorate may make comments pertaining
 only to the inclusion of investments and expenditures not
 contained in the Investment Plan or in its duly approved
 amendments or pertaining to numerical errors, and must do so
 within 90 days from receipt and access to the documentation
 discussed in 7.1.1, 7.1.2 and 7.1.3. In addition, the
 Directorate's comments must be substantiated, and the procedure
 set forth in paragraph 2 of Article 100 of the General Mining
 Law, Legislative Decree No. 109 shall apply. If the Directorate
 raises no objections, the Sworn Statement and the Financial
 Statements are considered automatically approved.
 
 7.3  The total recoverable investment amount shall first be
 determined at the closing of fiscal year 1985 on the basis of the
 amounts originally invested, by express or tacit approval of the
 work and acquisitions effected in implementing the Tintaya
 Project.
 <PAGE>
 
 At the closing of subsequent fiscal years, the recoverable
 investment shall be calculated by using the amount determined as
 a recoverable investment   as indicated in the preceding
 paragraph   and deducting depreciation and amortization, and by
 additionally deducting the amount that has already been recovered
 by following the procedure set forth in 8.2 of this Agreement.
 
 7.4  The recovery of the investment subject to this Agreement
 shall begin in fiscal year 1986, i.e. beginning with the fiscal
 year following the year in which the total amount of recoverable
 investments shall be determined in keeping with 7.3.
 
 
 ARTICLE EIGHT:  INVESTMENT RECOVERY PROGRAM AND DURATION OF
 CONTRACTUAL BENEFITS AND GUARANTEES.
 
 8.1  To facilitate the estimatation of the investment
 recuperation period as of the fiscal year following that in
 which, upon the conclusion of the Investment Plan, the total
 recoverable investment is determined, an Investment Recuperation
 Schedule is being attached as Enclosure IV and will form an
 integral part of this Agreement. The Schedule shows, among
 others, expenditures and/or assets and/or cash amounts designated
 for the implementation of the Investment Plan, such as
 infrastructure, studies, preliminary development of the mine,
 exploration, procurement of mine and plant equipment, facilities,
 buildings and other fixed assets necessary for day-to-day
 operations, loan interest charges, working capital, and in
 general all items considered investments under Article 37 of
 Supreme Decree No. 027-81-EM/VM.
 
 To this effect and in accordance with the aforementioned Article
 37 and with paragraph 3 of Article 159 of the General Mining Law,
 the word "investment" includes all amounts capitalized during the
 period between the starting and completion dates of the work.
 
 8.2  The investment recovery period is the timespan which begins
 the fiscal year following that in which, upon the conclusion of
 the Investment Plan, the total recoverable investment amount is
 established, and ends on the day when the Corporation has
 recovered the invested sums in the manner set forth in Article
 159 (paragraph 1) of the General Mining Law, i.e. by deducting
 
 <PAGE>
 income tax, INGEMMET dues and the 7% net profit share due its
 workers during the first seven years following production startup
 from gross earnings; or, in the event these first seven (7) years
 elapse without recovery of investment, by deducting the net
 shares and the capital shares due the workers in fulfillment of
 the Mining Compact.
 
 To this effect, the corporate income tax to be deducted from
 gross earnings shall be calculated in accordance with the
 provisions of Article 133 of the General Mining Law, regulated by
 Title I of Supreme Decree No. 027-81-EM/VM and Article 7.3 of
 this Agreement.
 
 Article 139 of the General Mining Law and paragraph 1 of Article
 39 of Supreme Decree No. 027-84-EM/VM provide that "gross
 earnings" are the difference between the net sale price (for
 domestic sales) or between the FOB value (for foreign sales), and
 the direct or indirect costs, without deducting applicable
 depreciations and amortizations therefrom.
 
 8.3  To determine the exact duration of this Agreement, the
 Corporation shall keep a Special Auxiliary Book, in which the
 investment currency, the total original recoverable investment
 amount established in accordance with 7.2 and 7.3, as well as the
 amount recovered with the earnings, shall be recorded from fiscal
 year to fiscal year as provided in 8.2.
 
 As indicated in the preceding paragraph, within the same
 timeframe as that established for filing the sworn income tax
 return, the Corporation shall submit a sworn statement to the
 General Mining Directorate which shall contain information
 pertaining to the recoverable investment as of the close of the
 fiscal year, the amount from the gross profit that was applied
 towards its recovery, a breakdown of how these amounts were
 calculated, and the balance that remains to be recovered, if
 applicable.
 <PAGE>
 The year in which the recoverable investment is completed, the
 Corporation shall, within 180 days from the last day of the month
 of such completion, submit to the General Mining Directorate and
 the Directorate of Revenues a special Sworn Statement specifying
 the date of the said recovery which shall be acknowledged by
 Supreme Resolution following verification, and countersigned by
 the Secretary of Energy and Mining and the Secretary of Economy,
 Finance and Trade.
 
 8.5  The Corporation shall also grant the General Mining
 Directorate and the Directorate of Revenues, at the location
 where it maintains its books, access to any data and records that
 may be needed to verify its reports.
    
 Without prejudice to the provision in this Agreement which
 requires the recording of the recoverable investment and its
 recovery in the Special Auxiliary Book, the Corporation's Balance
 Sheet shall reflect the total amount of the original recoverable
 investment under special memorandum accounts.
 
 8.6  In terms of the recoverable investment and the granting of
 contractual benefits and guarantees, including the lowered income
 tax rate provided under Article 9.5, the term of this Agreement
 shall begin as of the fiscal year following that in which the
 Investment Plan is completed and the total investment amount is
 approved in accordance with the provisions of Article 7, above.
 It shall end when the recovery of the investment has been
 accomplished, except for the benefit represented by the lower
 income tax rate, which will continue for another five (5) fiscal
 years following investment recovery.
 
 8.7  Under Article 42 of Supreme Decree No. 027-84-EM/VM, the
 provision in Article 8.6 applies regardless of the fact that the
 benefits and guarantees referred to in Article 157 of the General
 Mining Law are granted simultaneously with the signing of this
 Agreement and in view of the legal provisions applicable at the
 time the Agreement takes effect. These provisions remain
 unchanged to the Agreement beneficiary, except that a more
 
 <PAGE>
 favorable tax rate may be offered in the future. The income tax
 rate, however, will not be changed during the term, plus another
 five years after the Agreement ends, as stipulated in Article
 9.7.
 
 ARTICLE NINE:  CONTRACTUAL GUARANTEES.
 
 In accordance with Article 157 of the General Mining Law and
 Article 45 of Supreme Decree No. 027-84-EM/VM, the Government
 hereby makes the Corporation the following guarantees for the
 contractual term specified in Article 8.6 and without prejudice
 to the tenor of Article 8.7:
 
 9.1  That the marketing of the Corporation's products shall be
 effected in accordance with the standards outlined on the subject
 by Chapter I of Title III of the General Mining Law and Chapter V
 of Supreme Decree No. 025-82-EM/VM   the Regulation supporting
 the aforementioned Law  , i.e. that by virtue of this Agreement
 the Government guarantees the Corporation a free hand in the sale
 and export of its products from the Tintaya Project.
 Specifically, the Government may apply no measure which might:
 
    9.1.1  Restrict the Corporation's capacity to sell its
 products anywhere, after the Nation's domestic consumer needs
 have been met in accordance with the provisions referred to in
 the foregoing text. 
 
    9.1.2  To halt or postpone such sales and/or exportation.
 
    9.1.3  To require that the Corporation sell its products in
 any market, whether domestic or foreign, at prices that are lower
 than the prices it could obtain in the international marketplace
 where it sells most of its exports. In this regard and in
 accordance with domestic consumer statistics, the Corporation is
 therefore authorized to export more than 80% of its total
 production.
 
    9.1.4  To require payment for such products on the basis of
 barters or against currencies that are not valid for
 international payments.
 <PAGE>  
 9.2  In accordance with the provisions of Article 149 of the
 National Constitution and Article 157 of the General Mining Law,
 the Central Reserve Bank of Peru, in representation of the
 Executive Branch, is a participant to this Agreement and grants
 the mine producer the following guarantees over the term of the
 Agreement:
 
    a.  To hold foreign currency from the sale of its products,
 under foreign exchange regulations in effect at the time the
 Agreement is signed;

    b.  To not be discriminated against in matters relating to
 foreign exchange, and
 
    c.  In the event the foreign currency system is deregulated,
 the mine producer shall be able to enjoy increased benefits over
 the period of such deregulation, and these benefits shall be
 equitably applied.
 
    If these benefits are cut, the mine producer shall be able
 to continue enjoying those in effect at the time this Agreement.
 
    It should be noted that the currency exchange regulations
 whose stability is guaranteed for the duration of this Agreement
 are spelled out in Decree Law No. 21953 and its amendments, and
 by the exchange resolutions issued by the Central Reserve Bank of
 Peru in accordance with the aforementioned Decree Law No. 21953
 in effect at the signing of this Agreement.
 
 9.3  That it shall have the right to apply on its fixed assets an
 overall annual write-off rate of up to 20%. The Corporation may
 change this rate on an annual basis without requiring
 authorization from the Directorate General of Revenues, provided
 the overall annual 20% cap is not exceeded.
 
 9.4  In accordance with the provisions of subsection 4 of Article
 157 of the General Mining Law and Article 44, paragraph 2 of the
 Supreme Regulatory Decree No. 027-84-EM/VM, the Corporation shall
 be granted a one third reduction on the total amount of Income
 Tax calculated by the Corporation. It should be noted that this
 benefit applies to the Corporation during the term of the
 Agreement plus an additional five (5) years [following its
 expiration].
 <PAGE>
 
 9.5  That the Corporation shall keep its books in U.S. dollars in
 view of the fact that, as noted in Article 9.1.3, it intends to
 export at least 80% (eighty percent) of its production.
 
 To obtain this benefit, the Corporation shall:
 
    9.5.1  Change its account books to U.S. dollars beginning
 with the fiscal year following that in which this Agreement takes
 effect. The changeover   to be conducted in keeping with
 applicable international accounting procedures as established by
 the International Commission for Accounting Standards, and
 accompanied by an opinion from an independent accounting firm
 previously approved by the General Mining Directorate at the
 Corporation's suggestion  , shall specify that the investment
 amount is in historical United States dollars, without prejudice
 to the provisions of Decree Law No. 19039.
 
    9.5.2  At the closing of the fiscal year during which this
 Agreement is signed, two balance sheets shall be prepared, one in
 national currency and one in U.S. dollars. All liabilities for
 said business year shall be shown on the balance sheet in Gold
 Soles. The balance sheet in national currency must reflect the
 revaluations of assets and the adjustments in the amount of
 assets due to possible exchange rate fluctuations which may have
 taken place.
 
    9.5.3  If the term of this Agreement ends before one or more
 five-year periods have elapsed in which the books were kept in
 U.S. dollars, the Corporation shall change the accounts back to
 national currency beginning with the next fiscal year, and in so
 doing shall adhere to the same rules and authorizations referred
 to under Article 9.6.1.
 
    9.5.4  The accounting adjustments arising as a result of the
 conversion to U.S. dollars and to Gold Soles after the contract
 term, shall not be computable for Income Tax purposes.
 <PAGE>
 
    9.5.5  The Ministry of Economy, Finance and Trade shall issue
 a Supreme Decree spelling out the regulations Corporation shall 
 observe in complying with its tax obligations.  For tax payments 
 in Gold Soles, said Decree shall establish the exchange rate that 
 is the most favorable to the State.
 
    9.5.6   It is expressly pointed out that during the period
 the Corporation is subject to keeping its accounts in U.S
 dollars, it shall be prohibited from revaluing its assets.
 
 9.6  The Corporation shall enjoy Tax Stability, both in terms of
 Tintaya Project and the product it may extract therefrom, and no

 paying a total of US$ 246,933,750.60 (two hundred and
 forty-six million nine hundred and thirty-three thousand seven
 hundred and fifty and 60/100 U.S. Dollars), by submitting:
 
    
a.  The respective entry in the Stock Registry and Transfer
    Book and the Agreement signed with MINERO PERU, S.A.;
    
b.  A certificate issued by the Central Reserve Bank of Peru,
    the National Bank or the local bank involved in the
    transaction, verifying that the funds, in the amount of US$
    214,071,250.60 (two hundred and fourteen million
    seventy-one thousand two hundred and fifty and 60/100 U.S.
    Dollars), were channeled through the National Finance
    System; and
    
c.  A certificate issued by the Directorate General of Public
    Credit of the Ministry of Economy and Finance documenting
    the delivery of eligible foreign debt debentures in the
    amount of US$ 55,000,000 (fifty-five million and 00/100

    32,862,500 (thirty-two million eight hundred and sixty-two

 The debentures referred to in the preceding paragraph shall be
 verified within no more than 30 (thirty) calendar days from
 the deadline for their fulfillment, as established in Clause
 Two. Failure to comply with these provisions shall constitute
 grounds for termination of the Agreement.
 
 FIFTH.   This Judicial Stability Agreement shall be in effect
 for ten years from its effective date. Consequently, it shall
 not be modified unilaterally by either party during this 
<PAGE>
 period, even in the event of a change in national legislation,
 whether it be a beneficial or prejudicial modification for
 either party to this Agreement.
 
 SIXTH.   MAGMA and GLOBAL shall have a once only right to
 waive the Judicial Stability terms established in this
 Agreement. Notification to CONITE to this effect shall be in
 writing and shall take effect on the date notification is
 received.
 
 Should MAGMA and GLOBAL exercise their right to waive the
 Stability Agreement, as stated in this Clause, they shall
 automatically become subject to regular legislation.
 
 SEVENTH.   Both MAGMA and GLOBAL shall have the right to
 assign their contractual status in this Agreement, provided
 the obligations assumed under the CONTRACT with Minero Peru
 S.A. are met. For the assignment of the contractual status to
 be valid, MAGMA and GLOBAL shall previously obtain CONITE's
 authorization which shall take the form of an Addendum to this
 Agreement.
 
 It is understood that the assignment of contractual status by
 MAGMA and GLOBAL, between themselves or to another investor,
 would not extend the term of the Agreement referred to in
 Clause Five.
 
 EIGHTH.   This Judicial Stability Agreement may be amended by
 mutual agreement of the parties, except for the effective term
 established in Clause Five. Nor may the investment amount be
 reduced to below the limit established in Subsection e) of
 Article 16 of the Regulation, or in any other manner contrary
 to the provisions of the Contract.
 
 To this effect, MAGMA and GLOBAL shall submit a request to
 CONITE, to be processed in the same manner as the signing of
 this Agreement.
 
 NINTH.   It being the intention of the parties that any
 problems which may arise regarding the fulfillment of this
 Agreement be resolved as expeditiously as possible, it is
 henceforth agreed that any litigation, controversy or claim
 between the parties regarding the interpretation, execution or
 validity of this Agreement shall be resolved by legal
 arbitration.
 
 The arbitration shall take place in Lima, through an
 Arbitration Court comprised of three members. Each of the
 parties shall appoint one member and the two members thus <PAGE>
<PAGE>
 designated shall appoint the third. The arbitrators are
 expressly empowered to rule on the controversy under
 arbitration.
 
 Should one party fail to appoint an arbitrator within fifteen
 days of receipt of the request from the party calling for the
 arbitration, or if within fifteen days after the last
 arbitrator was appointed by the parties, the two arbitrators
 fail to agree on the third, the Lima Chamber of Commerce shall
 appoint him at the request of either party.
 
 The arbitration process shall not exceed sixty working days
 following the appointment of the last arbitrator, and shall be
 subject to the General Arbitration Law approved by Decree Law
 No. 25935 and/or the rules which may replace or amend said
 Law.
 
 The cost arising from the application of this clause shall be
 borne equally by the contracting parties.
 
 TENTH.   The following shall be cause for fully justified
 termination of this Judicial Stability Agreement without need
 for prior communication:
 
    
1.  Failure on the part of MAGMA or GLOBAL to make the
    investment agreed in Clause Two.
 
    
2.  Failure on the part of MAGMA or GLOBAL to document
    compliance with the requirement stated in Clause Four.
 
    
3.  Assignment of the contractual status by MAGMA or GLOBAL
    without the corresponding prior authorization of CONITE,
    in accordance with Clause Seven.
 
    
4.  Failure on the part of MAGMA or GLOBAL to fulfill the
    obligations stated in the CONTRACT.
 
 Should MAGMA or GLOBAL incur in any of the aforementioned
 causes for termination of this Agreement, and if due to the
 Judicial Stability provided hereunder they made lower fiscal
 payments than they would have paid without this Agreement,
 MAGMA and GLOBAL shall be required to make reimbursement to
 the Government of the updated tax amount for which they would
 have been liable had they not signed this Agreement, plus any
 corresponding surcharges as provided in the Tax Code.
 
 It shall be understood that if, in the event referred to in
 the previous paragraph, MAGMA or GLOBAL made higher tax
 payments due to this Agreement, the Government shall be under
 no obligation to make any kind of reimbursement.
