                              W I T N E S S E T H:

         WHEREAS, the Company desires to sell and issue to the Investors, and
the Investors wish to purchase from the Company, an aggregate of $6,000,000

conditions set forth herein; and

         WHEREAS, the Notes will be convertible into shares ("COMMON SHARES") of

terms thereof, and the Investors will have registration rights with respect to
such Common Shares, pursuant to the terms of that certain Registration Rights

         NOW, THEREFORE, in consideration of the foregoing premises and the
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:


                                   ARTICLE I

                           PURCHASE AND SALE OF NOTES

         Section 1.1 Issuance of Notes. Upon the following terms and conditions,
the Company shall issue and sell to each Investor severally, and each Investor
severally shall purchase from the Company, the principal amount of Notes
indicated next to such Investor's name on Schedule I attached hereto. With
respect to the Notes issued to each Investor, 50% of the principal amount shall
be convertible into Common Shares at the Floating Conversion Price (as defined
in the Notes) and 50% of the principal amount shall be convertible into Common
Shares at the Capped Conversion Price (as defined in the Notes). In addition,
Schedule I shall also indicate the Restricted Ownership Percentage (as defined
in the Notes) applicable to the Notes purchased by each Investor. Each Note
shall indicate whether it is convertible at the Floating Conversion Price or the
Capped Conversion Price.

              (a) Purchase Price. The purchase price for the Notes to be 
acquired by each Investor (the "PURCHASE PRICE") shall be the Purchase Price set
forth next to such Investor's name on Schedule I.


   2

         (b) The Closing.

                  (i) Subject to the fulfillment or waiver of the conditions set
         forth in Article V hereof, the closing of the purchase and sale of the
         Notes (the "Closing") shall take place at the offices of Kleinberg,
         Kaplan, Wolff & Cohen, P.C., on or about January 28, 1999, or earlier
         if the Investors so determine, or such other date as the Investors and
         the Company may agree upon (the "Closing Date").

                  (ii) On the Closing Date, the Company shall deliver to each
         Investor the Notes purchased by it (with the aggregate principal amount
         of such Notes as requested by such Investor) at the Closing registered
         in the name of such Investor or its nominee. The delivery of payment by
         each Investor of the Purchase Price applicable to it as set forth in
         Section 1.1 and Schedule I shall constitute a payment delivered to the
         Company in satisfaction of such Investor's obligation to pay the
         Purchase Price hereunder. At the option of the Investors, the Purchase
         Price may be delivered net of the expenses of the Investors incurred
         pursuant to Section 3.4. In addition, each party shall deliver all
         documents, instruments and writings required to be delivered by such
         party pursuant to this Agreement at or prior to the Closing.

as a foreign corporation to do business and is in good standing in every
jurisdiction in which the nature of the business conducted or property owned by
it makes such qualification necessary other than those in which the failure so
to qualify would not have a Material Adverse Effect. "MATERIAL ADVERSE EFFECT"
means any adverse effect on the business, operations, properties, or financial
condition of the entity or any subsidiary thereof with respect to which such
term is used and which is (either alone or together with all other adverse
effects) material to such entity, and any material adverse 



                                       2

effect on the transactions contemplated under this Agreement, the Notes and the

              (b) Authorization; Enforcement. (i) The Company has all requisite
corporate power and authority to enter into and perform this Agreement, the
Notes and the Registration Rights Agreement and to issue the Notes in accordance
with the terms hereof, (ii) the execution and delivery of this Agreement, the
Notes and the Registration Rights Agreement by the Company and the consummation
by it of the transactions contemplated hereby and thereby, including the
issuance of the Notes, have been duly authorized by all necessary corporate
action, and no further consent or authorization of the Company or its Board of
Directors (or any committee or subcommittee thereof) or stockholders is
required, (iii) this Agreement, the Notes and the Registration Rights Agreement
have been duly executed and delivered by the Company, (iv) this Agreement, the
Notes and the Registration Rights Agreement constitute valid and binding
obligations of the Company enforceable against the Company in accordance with
their terms, except (A) as such enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws
relating to, or affecting generally the enforcement of creditors' rights and
remedies or by other equitable principles of general application, and (B) to the
extent the indemnification provisions contained in this Agreement and the
Registration Rights Agreement may be limited by applicable federal or state
securities laws. 

              (c) Capitalization. 

                    (i) As of the date of this Agreement, the authorized capital
               stock of the Company consists of 600,000,000 shares of Common

               there are 259,408,558 shares of Common Stock and no shares of
               Preferred Stock currently issued and outstanding.

                    (ii) After the Closing, 69,740,502 shares of Common Stock
               and no shares of Preferred Stock will be reserved for issuance to
               persons other than the Investors. All of the outstanding shares
               of the Company's Common Stock have been validly issued and are
               fully paid and nonassessable. No shares of capital stock are
               entitled to preemptive rights; and there are as of the date
               hereof outstanding options for 4,849,000 shares of Common Stock
               and 7,084,500 shares of Common Stock available for future option
               grants. Except as set forth in Schedule 2.1, there are no other
               scrip, rights to subscribe to, calls or commitments of any
               character whatsoever relating to, or securities or rights
               exchangeable or convertible into, any shares of capital stock of
               the Company, or contracts, commitments, understandings, or
               arrangements by which the Company is or may become bound to issue
               additional shares of capital stock of the Company or options,
               scrip, rights to subscribe to, or commitments to purchase or
               acquire, any shares, or securities or rights convertible into

                    (iii) Attached hereto as Exhibit 2.1(c) is (A) a true and
               correct copy of the Company's Certificate of Incorporation (the
               "CHARTER"), as in effect on the date hereof, and (B) a true and
               correct copy of the Company's By-Laws, as in effect on the date
               hereof (the "BY-LAWS"). 

              (d) Issuance of Common Shares. The Common Shares are duly
authorized and reserved for issuance and, upon conversion of Notes in accordance
with their terms (including receipt by the Company of the Notes being converted
or a lost bond affidavit), such Common Shares, will be validly issued, fully
paid and non-assessable, free and clear of any and all liens, claims and
encumbrances, and entitled to be traded on the New York Stock Exchange ("NYSE")
(or the American Stock Exchange, or the Nasdaq National Market System,
collectively with the NYSE, the "APPROVED MARKETS"), and the holders of such
Common Shares shall be entitled to all rights and preferences accorded to a
holder of Common Stock. As of the date of this Agreement, the outstanding shares
of Common Stock are currently listed on the NYSE.

              (e) No Conflicts. The execution, delivery and performance of this
Agreement, the Notes and the Registration Rights Agreement by the Company and
the consummation by the Company of the transactions contemplated hereby and
thereby do not and will not (i) result in a violation of the Company's Charter
or By-Laws or (ii) conflict with, or constitute a default (or an event which
with notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation of,
any material agreement, indenture, patent, patent license or instrument to which
the Company or any of its subsidiaries is a party, or (iii) except as would not
reasonably be expected to have a Material Adverse Effect on the Company and its
subsidiaries, taken as a whole, result in a violation of any federal, state,
local or foreign law, rule, regulation, order, judgment or decree (including
Federal and state securities laws and regulations) applicable to the Company or
any of its subsidiaries or by which any property or asset of the Company or any
of its subsidiaries is bound or affected. The business of the Company and its
subsidiaries is being conducted in material compliance with all applicable laws,
ordinances or regulations of all governmental entities. The Company is not
required under Federal, state, local or foreign law, rule or regulation to
obtain any consent, authorization or order of, or make any filing or
registration with, any court or governmental agency in order for it to execute,
deliver or perform any of its obligations under this Agreement, the Registration
Rights Agreement and the Notes or issue and sell the Notes in accordance with
the terms hereof and issue the Common Shares upon conversion thereof, except for
(i) the registration provisions provided in the Registration Rights Agreement;
(ii) possible filing requirements under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended; and (iii) filing requirements under
applicable state securities or blue sky laws, provided that, for purposes of the
representation made in this sentence, the Company is assuming and relying upon
the accuracy of the relevant representations and agreements of the Investors
herein. 

              (f) SEC Documents; Financial Statements. The Common Stock of the
Company is registered pursuant to Section 12(b) of the Securities Exchange Act
of 1934, as amended (the "EXCHANGE ACT"), and the Company has filed all reports,
schedules, forms, statements and other documents required to be filed by it with
the Securities and Exchange 


                                       4
   5

Commission ("SEC") pursuant to the reporting requirements of the Exchange Act,
including material filed pursuant to Section 13(a) or 15(d), in addition to one
or more registration statements and amendments thereto heretofore filed by the
Company with the SEC (all of the foregoing including filings incorporated by
reference therein being referred to herein as the "SEC DOCUMENTS"). The Company
has delivered or made available to the Investors true and complete copies of all
SEC Documents (including, without limitation, proxy information and solicitation
materials and registration statements) filed with the SEC since December 31,
1996 and all annual SEC Documents filed with the SEC since December 31, 1995 and
prior to the date of this Agreement (the "Pre-Agreement SEC Documents"). The
Company has not provided to the Investors any material non-public information or
any information which, according to applicable law, rule or regulation, should
have been disclosed publicly by the Company but which has not been so disclosed.
As of their respective dates, the SEC Documents (as amended or supplemented to
this date, if applicable) complied in all material respects with the
requirements of the Exchange Act and the rules and regulations of the SEC
promulgated thereunder and other federal, state and local laws, rules and
regulations applicable to such SEC Documents, and none of the SEC Documents (as
amended or supplemented to this date, if applicable) contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. The financial
statements of the Company included in the SEC Documents (as amended or
supplemented to this date, if applicable) comply as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the SEC or other applicable rules and regulations with respect
thereto. Such financial statements have been prepared in accordance with
generally accepted accounting principles applied on a consistent basis during
the periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto or (ii) in the case of unaudited interim
statements, to the extent they may not include footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of operations
and cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments). 

              (g) Principal Exchange/Market. As of the date of this Agreement,
the principal market on which the Common Stock is currently listed for trading
is the NYSE. 

              (h) No Material Adverse Change. Since January 1, 1998, except as
disclosed in the Pre-Agreement SEC Documents, no Material Adverse Effect has
occurred or exists, and no event or circumstance has occurred that with notice
or the passage of time or both is reasonably likely to result in a Material
Adverse Effect with respect to the Company and its subsidiaries, taken as a
whole. 

              (i) No Undisclosed Liabilities. The Company and its subsidiaries
have no liabilities or obligations not disclosed in the Pre-Agreement SEC
Documents or on Schedule 2.1, other than those liabilities incurred in the
ordinary course of the Company's or its subsidiaries' respective businesses
since September 30, 1998, which liabilities, individually or in the aggregate,
do not or would not have a Material Adverse Effect on the Company or its
subsidiaries. 


                                       5
   6

              (j) No Undisclosed Events or Circumstances. No event or
circumstance has occurred or exists with respect to the Company or its
subsidiaries or their respective businesses, properties, prospects, operations
or financial condition, which, under applicable law, rule or regulation,
requires public disclosure or announcement by the Company but which has not been
so publicly announced or disclosed. 

              (k) No General Solicitation. Neither the Company, nor any of its
affiliates, or, to its knowledge, any person acting on its or their behalf has
engaged in any form of general solicitation or general advertising (within the
meaning of Regulation D under the Securities Act of 1933, as amended (the
"ACT")), in connection with the offer or sale of the Notes or Common Shares. 

              (l) No Integrated Offering. Neither the Company, nor any of its
affiliates, nor to its knowledge any person acting on its or their behalf has,
directly or indirectly, made any offers or sales of any security or solicited
any offers to buy any security, under circumstances that (i) would require
registration of the Notes or the Common Shares under the Act; and (ii) would be
integrated with the offering of the Notes under either the Act or the Rules of
any Approved Market limiting the amount of capital stock that may be issued
without stockholder approval. 

              (m) Form S-3. The Company is eligible to file the Registration
Statement (as defined in the Registration Rights Agreement) for secondary
offerings on Form S-3 (as in effect on the date of this Agreement) under the Act
and rules promulgated thereunder, and Form S-3 (as in effect on the date of this
Agreement) is permitted to be used under the Act and rules promulgated
thereunder for the contemplated resale of the Common Shares by the Investors.


              (n) No Shareholder Rights Plan. The Company has no stockholders
rights plan or plan or agreement with similar effect outstanding. 

              (o) No Litigation. Except as set forth in the Pre-Agreement SEC
Documents, no litigation or claim (including those for unpaid taxes) against the
Company or any of its subsidiaries is pending or, to the Company's knowledge,
threatened, which if determined adversely would reasonably be expected to have a
Material Adverse Effect on the Company and its subsidiaries, taken as a whole.
The legal proceedings described in the Pre-Agreement SEC Documents would not
reasonably be expected to have a Material Adverse Effect on the Company. 

              (p) Brokers. The Company has taken no action which would give rise
to any claim by any person for brokerage commissions, finder's fees or similar
payments by the Company or any Investor relating to this Agreement or the
transactions contemplated hereby. 

              (q) No Reliance. The Company has independently and without
reliance on Investors and based upon such information as it has deemed
appropriate, made its own analysis and decision to issue the Notes. Without
limiting the generality of the foregoing, the Company has not relied upon any
advice or representation of the Investors with respect to the effect of the
Notes on the price of the Common Stock. 



                                       6
   7

              (r) Other Investors. Except as set forth on Schedule 2.1, there
are no outstanding securities issued by the Company that are entitled to
registration rights under the Act. Except as set forth in Schedule 2.1, there
are no outstanding securities issued by the Company that are directly or
indirectly convertible into, exercisable into, or exchangeable for, shares of
Common Stock of the Company, that have anti-dilution or similar rights that
would be affected by the issuance of the Notes or the Common Shares. 

              (s) Certain Transactions. Except as disclosed in the Pre-Agreement
SEC Documents and on Schedule 2.1 and except as would not be required to be
disclosed pursuant to Item 404 of Regulation S-K promulgated under the Act, none
of the officers, directors, or employees of the Company is presently a party to
any transaction with the Company or any of its subsidiaries (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer, director, or any such employee has a substantial interest or
is an officer, director, trustee or partner. 

              (t) Permits; Compliance. The Company and each of its subsidiaries
is in possession of all franchises, grants, authorizations, licenses, permits,
easements, variances, exemptions, consents, certificates, approvals and orders
necessary to own, lease and operate its properties and to carry on its business
as it is now being conducted, the failure of which to obtain would be likely to
have a Material Adverse Effect on the Company and its subsidiaries, taken as a
whole (collectively, the "COMPANY PERMITS"), and there is no action pending or,
to the knowledge of the Company, threatened regarding suspension or cancellation
of any of the Company Permits except for such Company Permits the failure of
which to possess, or the cancellation or suspension of which, would not,
individually or in the aggregate, have a Material Adverse Effect on the Company.
Neither the Company nor any of its subsidiaries is in material conflict with, or
in material default or material violation of, any of the Company Permits. Since
January 1, 1997, except as disclosed on Schedule 2.1, neither the Company nor
any of its subsidiaries has received any notification with respect to possible
material conflicts, material defaults or material violations of applicable laws.


              (u) NYSE Contacts. The Company has not been contacted by the NYSE
since January 1, 1998, either orally or in writing, concerning potential
suspension or delisting of the Common Stock from the NYSE. 

              (v) Pirquitas Mine. With respect to the Pirquitas Mine located in
the Jujuy Province of Northwest Argentina (the "Pirquitas Mine") none of the
information received to date by the Company in connection with a feasibility
study or otherwise, would lead it to believe that the Company's publicly
announced pre-feasibility study estimates of operating costs, average annual
production, and useful life will not be materially accurate. 

         Section 2.2 Representations and Warranties of the Investors. Each of
the Investors, severally (as to itself) and not jointly, hereby makes the
following representations and warranties to the Company as of the date hereof
and on the Closing Date:



                                       7
   8

              (a) Due Organization; Authorization; Enforcement. (i) Such
Investor has been duly organized and is validly existing and in good standing in
the jurisdiction of its formation, (ii) Such Investor has the requisite power
and authority to enter into and perform this Agreement and the Registration
Rights Agreement and to purchase the Notes being sold hereunder, (iii) the
execution and delivery of this Agreement and the Registration Rights Agreement
by such Investor and the consummation by it of the transactions contemplated
hereby and thereby have been duly authorized by all necessary corporate or
partnership action, and (iv) this Agreement and the Registration Rights
Agreement have been duly executed and delivered by such Investor and constitute
valid and binding obligations of such Investor enforceable against such Investor
in accordance with their terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or
similar laws relating to, or affecting generally the enforcement of creditors'
rights and remedies or by other equitable principles of general application.

              (b) No Conflicts. The execution, delivery and performance of this
Agreement and the Registration Rights Agreement and the consummation by such
Investor of the transactions contemplated hereby and thereby do not and will not
(i) result in a violation of such Investor's organizational documents, or (ii)
conflict with any agreement, indenture or instrument to which such Investor is a
party, or (iii) result in a material violation of any law, rule, or regulation,
or any order, judgment or decree of any court or governmental agency applicable
to such Investor. Such Investor is not required to obtain any consent or
authorization of any governmental agency in order for it to perform its
obligations under this Agreement or the Registration Rights Agreement. 

              (c) Investment Representation. Such Investor is purchasing the
Notes for its own account and not with a view to distribution in violation of
any securities laws. Each Investor has been advised and understands that neither
the Notes nor the shares of Common Stock issuable upon conversion thereof have
been registered under the Act or under the "blue sky" laws of any jurisdiction
and may be resold only if registered pursuant to the provisions of the Act or if
an exemption from registration is available, except under circumstances where
neither such registration nor such an exemption is required by law. Each
Investor has been advised and understands that the Company in issuing the Notes
is relying upon, among other things, the representations and warranties of the
Investors contained in this Section 2.2 in concluding that such issuance is a
"private offering" and is exempt from the registration provisions of the Act.

              (d) Accredited Investor. Such Investor is an institutional
"accredited investor" as defined in Rule 501(a)(1), (2), (3) or (7) promulgated
under the Act. The Investor has such knowledge and experience in financial and
business matters in general and investments in particular, so that such Investor
is able to evaluate the merits and risks of an investment in the Notes and to
protect its own interests in connection with such investment. In addition (but
without limiting the effect of the Company's representations and warranties
contained herein), such Investor has been given the opportunity to request and
has received such information as it considers necessary or appropriate for
evaluating the merits and risks of the purchase of the Notes and deciding
whether to purchase the Notes pursuant hereto. Each Investor acknowledges that
its investment in the Notes involves a high degree of risk. In the normal course
of its 


                                       8
   9

business, each Investor invests in securities similar to the Notes. Each
Investor has sought such accounting, legal and tax advice as it has considered
necessary to make an informed investment decision with respect to the Notes.
Each Investor acknowledges that it is able to bear the economic risk of loss of
its investment in the Notes. 

              (e) Rule 144. Such Investor understands that there is no public
trading market for the Notes, that none is expected to develop, and that the
Notes must be held indefinitely unless and until such Notes, or Common Shares
received upon conversion thereof are registered under the Act or an exemption
from registration is available. Such Investor has been advised or is aware of
the provisions of Rule 144 promulgated under the Act. 

              (f) Brokers. Such Investor has taken no action which would give
rise to any claim by any person for brokerage commissions, finder's fees or
similar payments by the Company or such Investor relating to this Agreement or
the transactions contemplated hereby. 

              (g) Reliance by the Company. Such Investor understands that the
Notes are being offered and sold in reliance on a transactional exemption from
the registration requirements of Federal and state securities laws and that the
Company is relying upon the truth and accuracy of the representations,
warranties, agreements, acknowledgments and understandings of such Investor set
forth herein in order to determine the applicability of such exemptions and the
suitability of such Investor to acquire the Notes. 

                                  ARTICLE III

                                    COVENANTS

         Section 3.1 Registration and Listing; Effective Registration. Until
such time as no Notes are outstanding, the Company will cause the Common Stock
to continue at all times to be registered under Sections 12(b) or (g) of the
Exchange Act, will comply in all material respects with its reporting and filing
obligations under the Exchange Act, and will not take any action or file any
document (whether or not permitted by the Exchange Act or the rules thereunder)
to terminate or suspend such reporting and filing obligations. Until such time
as no Notes are outstanding, the Company shall continue the listing or trading
of the Common Stock on the NYSE or one of the other Approved Markets and comply
in all material respects with the Company's reporting, filing and other
obligations under the bylaws or rules of the Approved Market on which the Common
Stock is listed. The Company shall cause the Common Shares to be listed on the
NYSE or one of the other Approved Markets no later than the effectiveness of the
registration of the Common Shares under the Act, and shall continue such
listing(s) on one of the Approved Markets, for so long as any Notes are
outstanding. As used herein and in the Registration Rights Agreement and the
Notes, the term "EFFECTIVE REGISTRATION" shall mean that all registration
obligations of the Company pursuant to the Registration Rights Agreement and
this Agreement have been satisfied in all material respects, such registration
is not subject to any suspension or stop order (other than suspensions or stop
orders limited to a Suspension Grace Period (as defined in the Registration
Rights Agreement), which shall be excluded from this definition solely for
purposes of determining the number of days by which the mandatory conversion of
the Notes will be deferred), the prospectus for the Common Shares issuable upon

conversion of the Notes is current and deliverable and such Common Shares are
listed for trading on one of the Approved Markets and such trading has not been
suspended for any reason, and none of the Company or any direct or indirect
subsidiary of the Company is subject to any bankruptcy, insolvency or similar
proceeding.

         Section 3.2 New Notes on Conversion. Upon any conversion by an Investor
(or then holder of Notes) of the Notes pursuant to the terms thereof, the
Company shall issue and deliver to such Investor (or holder) within three (3)
Trading Days (as defined in the Notes) of the Conversion Date (as defined in the
Notes) a new Note or Notes for the principal amount of Notes which such Investor
(or holder) has not yet elected to convert but which are evidenced in part by
the Note(s) submitted to the Company in connection with such conversion (with
the principal amounts of such new Note(s) designated by such Investor or
holder). 

         Section 3.3 Replacement Notes. The Notes held by any Investor (or then
holder) may be exchanged by such Investor (or such holder) at any time and from
time to time for Notes with different principal amounts representing an equal
aggregate principal amount of Notes, as requested by such Investor (or such
holder) upon surrendering the same. No service charge will be made for such
registration or transfer or exchange. 

         Section 3.4 Expenses. The Company shall pay, at the Closing and
promptly upon receipt of any further invoices relating to same, all reasonable
due diligence fees and expenses and reasonable attorneys' fees and expenses of
the Investors' Counsel, up to a maximum amount of $40,000, incurred by the
Investors in connection with the preparation, negotiation, execution and
delivery of this Agreement, the Registration Rights Agreement, the Notes and the
related agreements and documents and the transactions contemplated hereunder and
thereunder. At the Closing, the Company shall pay the amount due for such fees
and expenses (which may include fees and expenses estimated to be incurred for
completion of the transaction including post-closing matters). In the event such
amount is ultimately less than the actual fees and expenses, in each case up to
the applicable maximum amounts provided in this Section 3.4, the Company shall
promptly pay such deficiency upon receipt of an invoice regarding same. Section

         3.5 Securities Compliance. The Company shall notify the SEC and the
NYSE, in accordance with their requirements, of the transactions contemplated by
this Agreement, the Notes and the Registration Rights Agreement, and shall take
all other necessary action and proceedings as may be required and permitted by
applicable law, rule and regulation, for the legal and valid issuance of the
Notes hereunder and the Common Shares issuable upon conversion thereof. 

         Section 3.6 Notices. The Company agrees to provide all holders of Notes
with copies of all notices and information, including without limitation notices
and proxy statements in connection with any meetings, that are provided to the
holders of shares of Common Stock, contemporaneously with the delivery of such
notices or information to such Common Share holders. 

         Section 3.7 Use of Proceeds. The Company agrees that the net proceeds
received by the Company from the sale of the Notes hereunder shall be used for
working capital purposes and that a material portion of such proceeds shall be
applied to the operations of Sunshine 


                                       10
   11

Argentina, Inc., a wholly-owned subsidiary of the Company ("Sunshine Argentina")
and the Company reserves the right to apply a portion of such proceeds to the
operations of Sunshine Exploration, Inc., a wholly-owned subsidiary of the
Company ("Sunshine Exploration"). 

         Section 3.8 Reservation of Stock Issuable Upon Conversion. The Company
agrees to reserve and at all times keep available solely for purposes of
conversion of the Notes, such number of authorized but unissued shares of Common
Stock that is at least equal to the Maximum Amount (as defined in the Notes),
which number may be reduced by the number of Common Shares actually delivered
pursuant to conversion of the Notes under the terms thereof and shall be
appropriately adjusted for any stock split, reverse split, stock dividend or
reclassification of the Common Stock. If at any time the number of authorized
but unissued shares of Common Stock shall not be sufficient to effect the
conversion of all the then outstanding Notes into the Maximum Amount of shares
of Common Stock (as so reduced and adjusted), the Company will take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purpose, including without limitation engaging in
best efforts to obtain the requisite shareholder approval. If at any time the
number of authorized but unissued shares of Common Stock is not sufficient to
effect the conversion of outstanding Notes into the Maximum Amount of Common
Shares, the Investors shall be entitled to, inter alia, the premium price
redemption rights provided in the Registration Rights Agreement. 

         Section 3.9 Best Efforts. The parties shall use their best efforts to
satisfy timely each of the conditions described in Article V of this Agreement.

         Section 3.10 Form D; Blue Sky Laws. The Company agrees to file a Form D
with respect to the Notes and Common Shares, as required under Regulation D and
to provide a copy thereof to each Investor promptly after such filing. The
Company shall, on or before the Closing Date, take such action as the Company
shall have reasonably determined is necessary to qualify the Notes and Common
Shares for sale to the Investors under applicable securities or "blue sky" laws
of the states of the United States (or to obtain an exemption from such
qualification), and shall provide evidence of any such action so taken to each
Investor on or prior to the Closing Date; provided, however, that the Company
shall not be required in connection therewith to register or qualify as a
foreign corporation in any jurisdiction where it is not now so qualified or to
take any action that would subject it to service of process in suits or
taxation, in each case, in any jurisdiction where it is not now so subject.

         Section 3.11 No Additional Issuances of Equity Securities;
Modifications of Other Notes. For so long as at least $2 million in Principal
Amount (as defined in the Notes) of Notes remains outstanding, the Company shall
not: (A) sell or otherwise dispose of any shares of its capital stock or issue
any additional shares of its capital stock or securities convertible,
exchangeable or exercisable into shares of its capital stock other than pursuant
to: (i) conversion of Notes; (ii) the exercise, conversion or exchange, on a
voluntary basis by the holders thereof and not upon demand or request of the
Company, of any warrants or options or other convertible or exchangeable
securities outstanding on the date hereof; and (iii) the future issuance of
employee and director stock options, not to exceed 7,084,500 shares of Common
Stock in the aggregate or; (B) make any amendments or modifications to the terms
or agree to any waivers of (i) the Company's 10% Senior Convertible Debentures
due November 24, 2002 (the "10% 


                                       11
   12

Debentures") or (ii) the Company's 8 7/8% Convertible Subordinated Debentures
due July 15, 2008 (the "8 7/8% Debentures"). 

         Section 3.12 Press Release. Immediately following the Closing, the
Company shall issue a press release, in accordance with NYSE rules (or the rules
of such other Approved Market on which the Common Stock is traded) and the
Securities Act. Investors shall have the opportunity to review such press
release prior to its issuance. No press release shall name the Investors except
as shall be required by law. If the Company fails to issue a press release
within 5 business days of the Closing, the Investors may issue a press release
covering the Closing and complying with any legal requirement applicable to the
Investors. 

         Section 3.13 Shareholder Rights Plan. None of the acquisitions of Notes
or Common Shares nor the deemed beneficial ownership of shares of Common Stock
prior to, or the acquisition of such shares pursuant to, the conversion of Notes
will in any event under any circumstances trigger the poison pill provisions of
any stockholders' rights or similar agreements, or plan having a similar effect.

         Section 3.14 Indebtedness. For so long as any Notes remain outstanding,
neither the Company nor any of its subsidiaries shall incur any new Indebtedness
(as defined below) or refinance existing Indebtedness, without the prior written
consent of the holders of the Notes, other than: (i) Indebtedness (including
refinanced Indebtedness) which is pari passu to the Notes; (ii) Indebtedness
(including refinanced Indebtedness) which by its terms is subordinated in right
of payment to the Notes; and (iii) Indebtedness incurred by a subsidiary of the
Company for the express purpose of funding the exploration, construction or
development of a specific project by such subsidiary; provided that, none of the
Indebtedness referred to in clauses (i), (ii) and (iii) above shall mature and
no principal payments shall be made with respect to such Indebtedness , prior to
the payment in full of the Notes. 

              As used herein, "Indebtedness" of any person, means any present or
future obligations, which shall include all obligations (i) which in accordance
with the generally accepted accounting principles in the U.S., shall be
classified upon the balance sheet of such person as liabilities, (ii) for
borrowed money, (iii) which have been incurred in connection with the
acquisition of any property (including without limitation, all obligations
evidenced by any indenture, bond, note, commercial paper or other similar
security, but excluding, in any case, obligations arising from the endorsement
in the ordinary course of business of negotiable instruments for deposit or
collection), (iv) obligations secured by any lien existing on property owned,
even though such person has not assumed or become liable for the payment of such
obligations, (v) obligations created or arising under conditional sale or other

         in the ordinary course of business; (v) intercompany indebtedness
         between or among the Company and any of its subsidiaries; provided that

         is expressly subordinated to the satisfaction in full of all
         obligations under the Notes;

                  (vi) Indebtedness represented by lease obligations, mortgage
         financings or purchase money obligations, in each case incurred for the

         Company or such subsidiary in an outstanding aggregate principal amount
         not to exceed $2,000,000; and

                  (vii) the incurrence by the Company or any of its subsidiaries

Company shall not combine its outstanding Common Stock into a smaller number of
shares (a "Reverse Split"). Subsequent to Effective Registration, if the Company
shall effect a Reverse Split, then the Maximum Amount (as defined in the Notes)
shall be increased by 50%.

         Section 3.16 Certain Mergers and Consolidations. For so long as any

consent of two-thirds of the principal amount of Notes outstanding, if the
transaction would, in the reasonable judgment of the Investors, be likely to
have a material adverse effect on the rights of Investors hereunder or under the
Notes or the Registration Rights Agreement.

                               EUROBOND COVENANTS

         Section 4.1 Payment of Additional Amount on Eurobonds. With respect to
the 8% Senior Exchangeable Notes due March 21, 2000, issued pursuant to the
Trust Deed by and among Sunshine Precious Metals, Inc., the Company and Marine
Midland Bank (the "Eurobonds"), the Company covenants that, pursuant to Section
6(B) of the Terms of the Eurobonds, it will cause the additional payment
required with respect to all Eurobonds pursuant to Sections 6(B)(i) or 6(B)(ii)
of the Terms of the Eurobonds (the "Additional Amount") to be paid in shares of
Common Stock; provided that such payment in shares shall be under circumstances
where such payment is permitted pursuant to the terms of the Eurobonds.

         Section 4.2 Certificates of Common Stock Delivered in Satisfaction of
Additional Amount. The Company covenants that upon receipt, at any time and from
time to time, from the Investor of (A) a certificate, substantially in the form
of Exhibit 4.2 A representing (i) that such Investor is not, and has not been
for the prior three months, an "affiliate" of the Company (within the meaning to
Rule 144 under the Act) and (ii) that such Investor has held its Eurobonds for
more than 2 years, or a certificate, substantially in the form of Exhibit 4.2B,
representing (x) that such Investor has held its Eurobonds for more than 1 year
and (y) shall sell any shares of stock received as payment of the Additional
Amount only upon compliance with the requirements of Rule 144, and (B) an
opinion of the Investor's counsel, substantially in the form of Exhibit 4.2C, to
the effect that, for purposes of Rule 144, the Investor's holding period for the
Additional Amount payable on the Eurobonds held by the Investor may be "tacked"
to the Investor's holding period of such Eurobonds, it shall issue unlegended
certificates to such Investor representing the shares of Common Stock issued
pursuant to Section 4.1 above. 

         Section 4.3 Payment of Note Indebtedness. The Company covenants that if
it shall, directly or indirectly (including through a subsidiary or affiliate),
redeem, retire, repurchase or make any payments, in any medium other than shares
of the Company's capital stock, of any amounts under any Note Indebtedness (as
defined below), other than regularly scheduled interest payments pursuant to the
terms thereof, whether pursuant to the terms thereof or otherwise, prior to the
maturity or stated maturity of the Eurobonds, then concurrently with such
redemption, retirement, repurchase or payment, (A) it shall, as to the 10%
Debentures and at the option of the Investors, also repurchase or cause to be
repurchased in cash, the Eurobonds held by the Investors on a pari passu basis
(i.e., the same percentage of the amounts outstanding on the Eurobonds held by
the Investors is paid as is paid on the 10% Debentures being paid down, so if
33% of the amounts owing on the 10% Debentures is being paid down, then 33% of
the amounts owing on the Eurobonds held by the Investors must be paid down) and
(B) the Company shall, at the option of the Investors, repurchase or cause to be
repurchased in cash, the Eurobonds held by the Investors in full prior to any
payment of principal on the 8 7/8% Debentures. 

              As used herein "Note Indebtedness" means the 10% Debentures and
the 8 7/8% Debentures.

the event that the Company receives any notice of default under (i) any Note
Indebtedness or (ii) any 


                                       14
   15

Indebtedness incurred after the issuance of the Notes that exceeds in the
aggregate $1,000,000, or other notice that could reasonably be expected to
result in the principal amount of such Note Indebtedness or Indebtedness being
accelerated or paid prior to maturity (a "Debt Notice"), then the Company shall
within 3 business days of the receipt of such Debt Notice, transmit a copy of
such notice to the Investors by facsimile pursuant to Section 8.4. The Company
shall publicly disclose such Debt Notice within 5 business days of the receipt
thereof. If the Company fails to make such public disclosure within such time
frame, the Investors may issue a press release disclosing such Debt Notice and
complying with any legal requirement applicable to the Investors.

         Section 4.5 Existing Indebtedness. For so long as the Investors hold
any Eurobonds:

              (a) If the Company or any of its subsidiaries or affiliates shall
enhance the credit of any Note Indebtedness, which shall include, without
limitation, the granting of any liens on assets, and the issuance of any
guarantees, capital contribution commitments, puts or letter of credit, then the
Eurobonds held by Investors shall be enhanced in the same manner on a ratable
basis (i.e., such enhancement shall be pari passu with the enhancement issued to
the Note Indebtedness being supported and the same proportion of amounts due and
owing on the Eurobonds held by the Investors shall be covered by such
enhancement, as with such Note Indebtedness).

              (b) The Company covenants that it shall comply, and cause all of
its subsidiaries to comply with the following:

                  (i) in the event that all or substantially all the Pirquitas
         Mine, or a controlling interest therein, is sold or disposed of, to one
         or more persons, in one or more transactions, then none of the proceeds
         shall be transferred from the entity selling or disposing of the
         Pirquitas Mine or a controlling interest therein unless such proceeds
         are used to pay the Note Indebtedness and the Eurobonds; and

                  (ii) Sunshine Argentina shall remain obligated with respect to
         the provisions of the Put Agreements, notwithstanding any transfer or
         issuance of its capital stock to any other person.

                                LEGEND AND STOCK

              (a) Upon payment therefor as provided in this Agreement, the
Company will issue one or more Notes in the name of the Investors or their
designees and in such principal amounts to be specified by the Investors prior
to (or from time to time subsequent to) Closing. Each Note and any certificate
representing Common Shares issued upon conversion thereof, prior to such Common
Shares being registered under the Act for resale or available for resale under
Rule 144 under the Act, shall be stamped or otherwise imprinted with a legend
substantially in the following form:

                  THESE SECURITIES HAVE NOT BEEN REGISTERED FOR OFFER OR SALE
UNDER THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS. THEY MAY NOT BE
SOLD OR OFFERED FOR SALE EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER SAID ACT AND ANY APPLICABLE STATE SECURITIES LAW OR AN APPLICABLE
EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS.

                  The Company agrees to reissue Notes without the legend set
forth above at such time as (i) the holder thereof is permitted to dispose of
such Notes and/or Common Shares issuable upon conversion thereof pursuant to
Rule 144 under the Act, or (ii) such Notes are sold to a purchaser or purchasers
who (in the opinion of counsel to the seller or such purchaser(s), in form and
substance reasonably satisfactory to the Company and its counsel) are able to
dispose of such shares publicly without registration under the Act.

                  Prior to the Registration Statement (as defined in the
Registration Rights Agreement) being declared effective, any Common Shares
issued pursuant to conversion of Notes shall bear a legend in the same form as
the legend indicated above; provided that such legend shall be removed from the
Common Shares and the Company shall issue new certificates without such legend
if (i) the holder thereof is permitted to dispose of such Common Shares pursuant
to Rule 144 under the Act, (ii) such Common Shares are registered for resale
under the Act, or (iii) such Common Shares are sold to a purchaser or purchasers
who (in the opinion of counsel to the seller or such purchaser(s), in form and
substance reasonably satisfactory to the Company and it counsel) are able to
dispose of such shares publicly without registration under the Act. Upon such
Registration Statement becoming effective, the Company agrees to promptly, but
no later than three (3) business days thereafter, issue new certificates
representing such Common Shares without such legend. Any Common Shares issued
after the Registration Statement has become effective shall be free and clear of
any legends, transfer restrictions and stop orders. Notwithstanding the removal
of such legend, each Investor agrees to sell the Common Shares represented by
the new certificates in accordance with the applicable prospectus delivery
requirements (if copies of a current prospectus are provided to such Investor by
