          someone other than the Consultant, and the Company in writing retains

     or which have no established public market, or if the consideration
     consists of property other than securities the value of such securities or
     other property shall be the fair market value thereof as mutually agreed by
     the Company and the Consultant. Legal consideration shall not include any
     indebtedness, or without limitation pension liabilities, guarantees and
     other obligations assumed, directly or indirectly, in connection with, or
     which survives the closing of, transaction. If the legal consideration to
     be paid is computed or payable in any foreign currency, the value of such
     foreign currency shall, for the purposes hereof be converted into U.S.

     consideration is payable.

          Consultant's or senior corporate finance personnel of the Consultant.

     C.   The use of the Consultant's name in any annual report of the Company,
          or any release or similar document, prepared by or on behalf of the
          Company or other, must have the prior approval of the Consultant
          unless the Company is required by law to include the Consultant's
          names in such annual report, other report or releases, in which event
          the Consultant will be furnished with a copy of such annual report,
          other report or release using the Consultant's names in advance of
          publication by or on behalf of the Company.

     D.   Should any purchases of securities be requested to be effected through

          profit sharing, pension or similar plan of the Company, for the
          account of the Company or the individuals or entities involved, such
          orders shall be taken by a registered account executive of the
          Consultant, shall not be subject to the terms of this Agreement, and
          the normal brokerage commission as charged by the Consultant will
          apply in conformity with all rules and regulations of the New York
          Stock Exchange, the National Association of Securities Dealers, Inc.,
          or other regulatory bodies. Where no regulatory body sets the fee, the
          normal established fee used by the Consultant shall apply.

     E.   The Consultant shall not disclose confidential information which it
          learns about the Company as a result of it's engagement hereunder,
          except for such disclosure and may be required for the Consultant to
          perform its duties hereunder.

12.  Indemnification. In consideration of Consultant's agreement to act on our
     behalf in connection with the matters decided herein, the Company agrees to
     indemnify and hold harmless Consultant and its affiliates and Consultant
     and its respective officers, directors, employees and agents and each other
     person, if any, controlling Consultant or any of its affiliates (Consultant
     and each such other person being an "Indemnified Person") from and against
     any losses, claims, damages or liabilities related to, arising out of or in
     connection with the engagement under this Agreement, and will reimburse
     each Indemnified Person for all reasonable expenses (Including reasonable
     fees and expenses of counsel) as they are incurred in connection with
     investigating, preparing, pursuing or defending any action, claim, suit,
     investigation or proceeding related to, arising out of or in connection
     with this Agreement, whether or not pending or threatened and whether or
     not any Indemnified Person is a party. The Company will not, however, be
     responsible for any losses claims, damage or liabilities (or expenses
     relating thereto) that are finally judicially determined to have resulted
     from the bad faith or gross negligence of any Indemnified Person. The
     Company also agrees that no Indemnified Person shall have any liability
     (whether direct or indirect, in contract or tort or otherwise), to the
     Company or its shareholders, directors, officers, affiliates, etc. for or
     in connection with this Agreement, except for any such liability for
     losses, claims, damages or liabilities incurred by such parties that are
     finally judicially determined to have resulted from gross negligence or
     recklessness of such Indemnified Person. In addition, if Consultant is
     required to respond to a subpoena or provide testimony relating to the
     Company, whether or not it specifically relates to this Agreement, the
     Company shall pay all legal fees and expenses as incurred relating to such
     proceedings.

     The Company will not, without Consultant's prior written consent, settle,
     compromise, consent to the entry of any judgment in or otherwise seek to
     terminate any action, claim, suit or proceeding in respect of which
     indemnification may be sought hereunder (whether or not any Indemnified
     Person is a party thereto) unless such a settlement, compromise, consent or
     termination includes a release of each indemnified Person from any
     liabilities arising out of such action, claim, suit or proceeding. No
     Indemnified Person seeking indemnification, reimbursement or contribution
     under this Agreement will, without the Company's prior written consent,
     settle, compromise, consent to the entry of any judgment in or otherwise
     seek to terminate any action, claim, suit, investigation or proceeding
     referred to in the proceeding paragraph.

     If the indemnification provided for in the first paragraph of this
     agreement is judicially determined to be unavailable (other than in
     accordance with the third sentence of the first paragraph hereof) to an
     Indemnification Person in respect of any losses, claims, damages or
     liabilities referred to herein, than, in lieu of indemnifying such
     Indemnified Person hereunder, the Company shall contribute to the amount
     paid or payable by such Indemnified Person as a result of such losses,
     claims, damages or liabilities (and expenses relating thereto) (I) in such
     proportion as is appropriate to reflect the relative benefits to
     Consultant, on the one hand, and the Company, on the other hand, of the
     engagement or (ii) if the allocation provided by clause (I) above is not
     available, in such proportion as is appropriate to reflect not only the
     relative benefits referred to in such clause (I) but also the relative
     fault of each of Consultant and the Company, as well as any other relevant
     equitable considerations; provided, however, in no event shall Consultant's
     aggregate contribution to the amount paid or payable exceed the aggregate
     amount of cash fees actually received by it under this Agreement.

13.  Severability. Every provision of this Agreement is intended to be several.
     If any term or provision hereof is deemed unlawful or invalid for any
     reason whatsoever, such unlawfulness or invalidity shall not affect the
     validity of the remainder of this Agreement.

statements, motions and applications and the agreements and instruments to be
entered into by the Sunshine Companies pursuant to the Plan and attached as

for the restructuring of the Company (the "RESTRUCTURING");

         WHEREAS, in connection with the Restructuring, the Company and the
Holders are entering into that certain Registration Rights Agreement of even
date herewith (the "REGISTRATION RIGHTS AGREEMENT");

         WHEREAS, upon the completion of the Restructuring, assuming that there
have been no stock splits, dividends, combinations, reorganizations,

<PAGE>   2

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

         1. GRANT OF CALL OPTIONS.

                  (a) Subject to Section 1(b) below and the terms and conditions
         herein, Grantor hereby grants to each Holder a Call Option to purchase
         up to a certain maximum number of SAI Shares (as adjusted for Capital
         Structure Changes) at a certain purchase price per SAI Share (the
         "PURCHASE PRICE"), all as set forth in Schedule 1 annexed hereto.

                  (b) In the event that the Elliott Holders sell more than 50%
         of their shares of Common Stock initially received in the Restructuring
         (as adjusted for Capital Structure Changes) or the Stonehill Holders
         sell more than 50% of their shares of Common Stock initially received
         in the Restructuring (as adjusted for Capital Structure Changes), then
         the number of SAI Shares that the Elliott Holders or the Stonehill
         Holders, respectively, are entitled to purchase as set forth in
         Schedule 1 hereto shall be reduced ratably to the extent that such
         Holders sold in excess of such amounts. For example, if the Elliott
         Holders were to sell 55% of their shares of Common Stock initially
         received in the Restructuring, then the maximum number of SAI Shares
         that the Elliott Holders could purchase, in the aggregate, upon the
         exercise of their Call Options would be reduced by a percentage equal
         to (55% - 50% ) x 2, or 10%. Schedule 1 shall be amended and
         redistributed to the parties hereto and the Pledge Agent (as defined in
         Section 4) shall be directed to reflect any such reductions.

         2. TERM. The term of each Call Option (the "TERM") shall commence on
the date upon which the Plan approved by the Bankruptcy Court goes effective
(the "CLOSING DATE") and shall expire upon the earlier of the following:

                  (a) the exercise in full of such Call Option,

                  (b) The market capitalization of the Company shall exceed $150
         million for at least 60 consecutive calendar days, and

                  (c) The ten year anniversary of the effective date of the Plan
         of Reorganization

; provided, however, that, with respect to (b) above, all of the Common Stock is
registered and freely tradeable during such 60-day-period (e.g., among other
things, (x) no Interfering Event has occurred, without giving effect to any
Suspension Grace Period (each as defined in the Registration Rights Agreement),
(y) the Holders are not restricted from trading because the Holders are in
possession of material, non-public information and (z) none of the events set

                  capitalization shall not have subsequently gone above $15
                  million for at least 30 calendar days (but if the market

                  set forth in this Agreement;

                           (vi) unless waived by all of the Holders, (A) any
                  person not designated by the Holders, other than management
                  directors, is serving as a member of the board of directors of
                  the Grantor or (B) any person designated by the Holders in

         written notice of the occurrence of any of the events described in (i),
         (ii), (iv), (v), (vi), (vii), (viii) or (ix).

                  (b) Exercise Notice. If any of the conditions to exercise set
         forth in Section 3(a) above shall have been met, then the Call Options
         may be exercised, at any time and from time to time, by each Holder in
         full or in part by the tendering of a written notice (the "EXERCISE
         NOTICE") to the Grantor and the Pledge Agent (as defined in Section
         4(b) below) at the address set forth in Section 9(c) herein. The
         Exercise Notice shall specify:

                                       3
<PAGE>   4

                           (i) the date on which the purchase is to take place
                  (the "PURCHASE DATE"), which may be the same date as the
                  Exercise Notice;

                           (ii) the number of SAI Shares with respect to which
                  the Holder is then exercising its Call Option (the "CALL
                  AMOUNT");

                           (iii) the aggregate purchase price for the Call
                  Amount (determined by multiplying the Purchase Price set forth
                  in Schedule 1 hereto by the Call Amount); and

                           (iv) whether the exercising Holder elects to pay the
                  aggregate purchase price in cash or by delivering shares of
                  Common Stock (pursuant to Section 3(c) and 3(d)(ii) below) in
                  lieu of cash.

         Upon receipt of the Exercise Notice as a result of which the Holders
         shall have acquired, in the aggregate, a majority of the SAI Shares,
         the Company and Grantor shall cause each officer and director of SAI to
         offer his or her resignation in writing to the Holder(s), which such
         resignation shall become effective upon the Purchase Date unless
         otherwise agreed to by the officer or director and the Holder(s).

                  (c) Cashless Exercise. If the exercising Holder elects to pay
         for the Call Amount by delivering shares of Common Stock, the number of
         shares of Common Stock to be delivered by the Holder(s) shall be
         computed using the following formula:

                                    X =  Y x  B
                                         ------
                                            A

                       where:   X = the number of shares of Common Stock to
                                    be delivered
                                Y = the number of SAI Shares included in the
                                    Call Amount
                                A = the Market Value (defined below) per share
                                    of Common Stock
                                B = the Purchase Price

         For the purposes of the foregoing, "MARKET VALUE" shall mean the price
         of one share of Common Stock determined as follows:

                           (i) if the Common Stock is listed on the New York
                  Stock Exchange or on the American Stock Exchange, the closing
                  price on such exchange on the date prior to the Purchase Date;

                           (ii) if (i) does not apply and the Common Stock is
                  listed on the NASDAQ National Market System, the NASDAQ
                  Small-Cap Market or the NASDAQ OTC Bulletin Board, the last
                  reported bid price on the day preceding the Purchase Date;

                           (iii) if neither (i) nor (ii) apply but the Common
                  Stock is quoted in the over-the-counter market, another
                  recognized exchange or on the pink sheets, the closing bid
                  price on the day preceding the Purchase Date; and

                                       4
<PAGE>   5

                           (iv) if neither clause (i), (ii) or (iii) above
                  applies, the fair market value of the Common Stock as
                  reasonably determined in good faith by the Company's board of
                  directors with the concurrence of an investment banker
                  acceptable to the Holders and with the concurrence of the
                  Holders.

                  (d) Purchase Date.

                           (i) On the Purchase Date, the Grantor shall deliver
                  beneficial ownership of the Call Amount to the Holder by
                  delivering, or causing the Pledge Agent (as defined in Section
                  4 below) to deliver, the certificates therefore together with
                  duly executed "stock powers". In the event that the Call
                  Amount is not delivered to the Holder in accordance with the
                  foregoing on a timely basis, the Holder may, by written
                  notice, rescind its exercise of the Call Option, in whole or
                  in part, reserving all rights to damages for breach of this
                  Agreement or any other Transaction Document.

                           (ii) On the Purchase Date, SAI agrees to register the
                  transfer of the shares of capital stock of SAI included in the
                  Call Amount to the name of the exercising Holder or its
                  designee. This obligation of SAI is and shall at all times be
                  valid and enforceable and SAI absolutely, unconditionally and
                  irrevocably waives any and all rights to assert any defense or
                  other objection to this obligation.

                           (iii) On the Purchase Date, provided that as a result
                  of the exercise of the Call Option, the Holders shall have
                  acquired, in the aggregate, a majority of the outstanding SAI
                  Shares, the written resignation of each director and officer
                  of SAI shall be delivered to the Holders and shall become
                  effective unless otherwise agreed to by the director or the
                  officer and the Holder(s) pursuant to Section 3(b) above.

                           (iv) In exchange for the above, on the Purchase Date,
                  the exercising Holder shall deliver (A) the aggregate purchase
                  price set forth in the Exercise Notice to the Grantor by wire
                  transfer in immediately available funds to an account
                  designated on Schedule 2 annexed hereto or such other account
                  as may be designated in writing by the Grantor from time to
                  time or (B) if the Holder opted for a cashless exercise in the
                  Exercise Notice, (1) the physical stock certificates
                  representing the Common Stock deliverable upon such cashless
                  exercise (as determined in accordance with Section 3(c) above)
                  or (2) in lieu thereof, provided the transfer agent of such
                  Holder is participating in the Depository Trust Company
                  ("DTC") Fast Automated Securities Transfer ("FAST") program,
                  upon request of the Grantor, the Holder shall use its best
                  efforts to cause its transfer agent to electronically transmit
                  such shares of Common Stock to the Grantor on the Purchase
                  Date by crediting the account of Grantor's prime broker with
                  DTC through its Deposit Withdrawal Agent Commission ("DWAC")
                  system. The parties agree to coordinate with DTC to accomplish
                  this objective.

                  (e) Transfer Tax. Transfers of the Call Amounts upon exercise
         of the Call Options shall be made without charge to the Holders for any
         transfer tax or other costs in respect thereof.

                  attached hereto as Exhibit 1 (the "PLEDGE AGREEMENT");

                           (ii) (A) the pledge of the SAI Shares by the Grantor
                  to the Pledge Agent for the ratable benefit of the Holders,
                  and (B) the delivery by the Grantor of the certificates
                  representing such SAI Shares together with duly executed
                  "stock powers" to the Pledge Agent in connection therewith;
                  and

                           (iii) the filing of certain UCC-1 financing
                  statements describing the SAI Shares with the appropriate
                  offices in Idaho and Delaware.

         delivery of SAI Shares to the Pledge Agent pursuant to the Pledge
         Agreement, Grantor will grant the Pledge Agent the right (and the
         obligation) to vote such SAI Shares as instructed by the Holders in
         accordance with the Pledge Agreement.

                  (f) Capitalization.

                           (i) SAI is a direct and wholly-owned subsidiary of
                  Grantor. The authorized capital stock of SAI consists of
                  10,000 shares of common stock. As of the date hereof, there
                  were 1,000 shares of common stock issued and outstanding, all
                  of which are owned legally and beneficially by Grantor, and no
                  shares of capital stock are reserved for issuance. All of the
                  outstanding shares of capital stock of SAI have been validly
                  issued and are fully paid and nonassessable. There are

         other liabilities or obligations (including, without limitation, claims
         existing under environmental or similar laws) that are not disclosed in
         the Plan or on Schedule 5(i) hereto other than those liabilities
         incurred in the ordinary course of such Sunshine Company's respective
         businesses since December 31, 1999, which liabilities, individually or
         in the aggregate, do not or would not have a Material Adverse Effect
         (as defined in the Transaction Documents) on such Sunshine Company.
         There are no liens, security interests or other encumbrances on, or
         with respect to, any asset of SAI other than a mortgage on the
         Pirquitas Mine to secure financing made to SAI by Highwood Partners,
         L.P. and Stonehill Capital Management, LLC..

                           "INDEBTEDNESS" means, with respect to any person or
         entity, all obligations (s) 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, (t) for borrowed
         money, (u) consisting of intercompany advances, (v) 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), (w)
         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, (x) obligations created or arising under conditional sale
         or other title retention agreement with respect to property acquired by
         such person, notwithstanding the fact that the rights and remedies of
         the seller, lender or lessor under such agreement in the event of
         default are limited to repossession or sale of such property, (y) for
         capitalized leases, (z) for all guarantees, whether or not reflected in
         the balance sheet of such person, and (aa) all reimbursement and other
         payment obligations (whether contingent, matured or otherwise) of such
         person in respect of acceptance or documentary credit. Notwithstanding
         the foregoing, the definition of the term Indebtedness will not apply
         to any of the following:

                           (i) trade debt to unaffiliated third parties incurred
                  in the ordinary course of business;

                           (ii) hedging obligations incurred in connection with
                  the ordinary course of business to protect against currency
                  exchange rate risks or precious metal price risks;

                           (iii) performance bonds or surety or appeal bonds
                  entered into in the ordinary course of business; and

                           (iv) Indebtedness represented by lease obligations,
                  mortgage financings or purchase money obligations, in each
                  case incurred for the purpose of financing all or any part of
                  the purchase price or cost of construction or improvements of
                  property used in the business of the Company or such
                  subsidiary in an outstanding aggregate principal amount not to
                  exceed $25,000.

                  (j) SAI Ownership of Pirquitas Mine. SAI is the sole record
         and beneficial owner of the silver mine in Argentina known as the
         "Pirquitas Mine" (the "PIRQUITAS MINE"), all real property and personal
         property relating to the mining operations thereon, and all rights and
         permits to develop and operate the Pirquitas Mine.

         6. COVENANTS OF SUNSHINE COMPANIES. During the Term of the Call Option,
each of the Sunshine Companies, severally and jointly, hereby covenants to the
Holders that:

                  (a) Corporate Existence. The Sunshine Companies shall maintain
         and preserve their individual corporate existence unless otherwise
         agreed to in writing by each of the Holders.

                  (b) Indebtedness. Neither the Grantor nor SAI shall incur
         Indebtedness or pledge, hypothecate, grant any lien with respect to or
         otherwise encumber any assets without the prior written approval of
         each of the Holders.

                  (c) Transfers, Liens, Etc.

                           (i) Except as otherwise provided in any Transaction
                  Document to the contrary, neither the Grantor nor SAI shall
                  split, combine or reclassify, sell, assign, divide, transfer,
                  dispose of, or pledge, hypothecate or otherwise encumber the
                  SAI Shares or any securities convertible into or exchangeable
                  for such SAI Shares, without the written consent of each of
                  the Holders.

                           (ii) Neither Grantor nor SAI shall create, incur or
                  permit to exist any security interest, lien or other
                  encumbrance on or with respect to any SAI Shares other than in
                  accordance with the Transaction Documents.

                           (iii) Any attempted transfer of SAI Shares in
                  contravention of the provisions of this Section 6(c) shall be
                  void and ineffectual and shall not bind or be recognized by
                  any Sunshine Company.

                           (iv) Except as required by this Agreement, SAI shall
                  not issue any additional shares of capital stock.

<PAGE>   10

                  (d) Subsidiaries. The Grantor and SAI shall not create, own or
         hold any interest in any subsidiary (other than the subsidiaries
         disclosed in the Transaction Documents) without the written consent of
         each Holder. Unless otherwise agreed to in writing by each of the
         Holders, in the event that the Grantor or SAI shall create, own or hold
         any interest in any subsidiary in accordance with the foregoing:

                           (i) the Grantor and SAI shall cause such subsidiary
                  to sign this Agreement as an additional party, at which time
                  all capital stock of the subsidiary ("SUBSIDIARY SHARES")
                  shall be treated the equivalent of SAI Shares for all purposes
                  hereunder;

                           (ii) the Grantor, SAI and such subsidiary shall
                  assume the equivalent obligations that the Grantor and SAI
                  have with respect to SAI Shares in connection with the
                  Subsidiary Shares (including, but not limited to, granting to
                  the Holders a first priority perfected security interest in
                  the Subsidiary Shares and perfecting such security interest in
                  accordance with Section 4(b) hereof); and

                           (iii) the Grantor, SAI and such subsidiary shall take

                  (e) Transfer of Assets.

                           (i) Neither Grantor nor SAI shall transfer any asset,
                  or a controlling interest therein (including, but not limited
                  to, any amounts received, directly or indirectly, by such
                  Sunshine Company from one or more of the Holders pursuant to
                  the Transaction Documents) to any of the other Sunshine
                  Companies or any affiliates of the Sunshine Companies
                  (including any subsidiaries of such Sunshine Company) without
                  the prior written approval of each Holder.

                           (ii) Neither Grantor nor SAI shall transfer any asset
                  or a controlling interest therein outside the ordinary course
                  of business.

                           (iii) Any attempted transfer in contravention of the
                  provisions of this Section 6(e) shall be void and ineffectual
                  and shall not bind or be recognized by the Company or SAI.

                  (f) Obligations of SAI. On each Purchase Date, SAI shall (i)
         register the transfer of the SAI Shares included in the Call Amount to
         the name of the exercising Holder or its designee and (ii) if as a
         result of the Call Option exercise, the Holders shall in the aggregate,
         have acquired a majority of the SAI Shares, take all such actions as
         are necessary to effectuate the resignation of each officer of SAI
         unless otherwise agreed to by the officer and the exercising Holder(s)
         pursuant to Section 3(b) above.

                  (g) No Conflicting Actions. No Sunshine Company shall take any
         action which is inconsistent or in conflict with the terms and
         provisions of this Agreement and the Pledge Agreement.

                  (h) No Modification. The obligations of the Sunshine Companies

                  (i) Accuracy of Representations and Warranties. The
         representations and warranties of each Sunshine Company will be true
         and correct in all material respects as of the date when made, except
         for representations and warranties of an earlier date, which will be
         true and correct in all material respects as of such date.

                  (j) Board of Directors. For so long as any Holder holds any
         Call Option, the directors of Grantor, other than management directors,
         shall be nominated solely by the Holders holding a Call Option, the
         Company agrees to vote the capital stock of Grantor in favor of such
         Holders' nominees and the Company agrees not to remove any director
         without the consent of the Holders holding Call Options. Furthermore,
         for so long as any Holder holds any Call Option, the Company agrees
         that it shall make no stockholder proposals with respect to Grantor and
         shall not nominate any directors (other than the nominees proposed by
         the Holders other than the management director).

                  (k) No Dividends or Other Distribution. No Sunshine Company
         shall, without the written consent of each of the Holders, declare or
         pay any dividends, purchase, redeem, retire, defease or otherwise
         acquire for value any of its capital stock or any warrants, rights or
         options to acquire such capital stock, now or hereafter outstanding,
         return any capital to its stockholders as such, make any distribution
         of assets, capital stock, warrants, rights, options, obligations or
         securities to its stockholders as such or issue or sell any capital
         stock or any warrants, rights or options to acquire such capital stock,
         or permit any of its subsidiaries to purchase, redeem, retire, defease
         or otherwise acquire for value any capital stock of a Sunshine Company
         or any warrants, rights or options to acquire such capital stock or to
         issue or sell any capital stock or any warrants, rights or options to
         acquire such capital stock.

                  (l) No Burdensome Agreements. No Sunshine Company shall become
         a party to any agreement or arrangement, or otherwise undertake any
         responsibility, that may prove to be materially burdensome on the
         Sunshine Company or its ability to comply with the provisions hereof.

                  (m) Transactions With Affiliates. Each Sunshine Company agrees
         that any transaction or arrangement between it or any of its
         subsidiaries and any affiliate or employee of the Sunshine Company
         shall be effected on an arms' length basis in accordance with customary
         commercial practice and, except with respect to grants of options and
         stock to service providers, including employees, shall receive the
         prior written approval of each Holder holding a Call Option.

         7. INDEMNIFICATION. Each of the Sunshine Companies, jointly and
severally, agrees to indemnify each Holder and hold it harmless from and against
(a) any loss, costs and damages (including reasonable attorney's fees) incurred

agreement in this Agreement or incurred in connection with the enforcement of
this indemnity; (b) any and all injuries, claims, damages, judgments,

costs and expenses (including, without limitation, reasonable fees and
disbursements of counsel whether involving a third party or a claim between the
parties), charges and encumbrances which may be incurred by or asserted against
a Holder in connection with or arising out of this Agreement other than those
resulting from Holder's breach of this Agreement; (c) any assertion, declaration
or defense of the Holders' rights or security interest under the provisions of
this Agreement or the Pledge Agreement in connection with the realization,
possession, safeguarding, insuring or other protection of the SAI Shares or in
connection with the collecting, perfecting or protecting of the Holders' liens
and security interests hereunder or under the Pledge Agreement.

         8. MISCELLANEOUS.

                  (a) Further Assurances. Each of the Sunshine Companies and
         each of the Holders shall promptly execute and deliver all further

         Agreement.

                  (g) Remedies Cumulative. Each Holder's rights and remedies
         under this Agreement and the Pledge Agreement shall be cumulative and
         non-exclusive of any other rights or remedies which it or he may have
         under any other Transaction Document or any other agreement or

         unenforceable in any jurisdiction shall, as to such jurisdiction, be
         ineffective to the extent of such illegality, invalidity, prohibition
         or unenforceability without invalidating the remaining terms and
         provisions hereof, and any such illegality, invalidity, prohibition or
         unenforceability in any jurisdiction shall not invalidate or render

         jurisdiction.

                  (i) Governing Law. This Agreement and the validity and
         performance of the terms hereof shall be governed and construed in

         contracts executed and to be performed entirely within such state.

                  (j) Jurisdiction. The Sunshine Companies and the Holders (i)
         hereby irrevocably submit to the exclusive jurisdiction of the state
         and federal courts in the State of Delaware for the purposes of any
         suit, action or proceeding arising out of or relating to this Agreement
         and (ii) hereby waive, and agree not to assert in any such suit, action
         or proceeding, any claim that it is not personally subject to the
         jurisdiction of such court, that the suit, action or proceeding is
         brought in an inconvenient forum or that the venue of the suit, action
         or proceeding is improper. To the fullest extent permitted by
         applicable law, the Sunshine Companies and the Holders consent to
         process being served in any such suit, action or proceeding by mailing
         a copy thereof to such party at the address in effect for notices to it
         under this Agreement and agrees that such service shall constitute good
         and sufficient service of process and notice thereof. Nothing in this
         Section 8(j) shall affect or limit any right to serve process in any
         other manner permitted by law.

                  (k) Specific Performance. The Sunshine Companies and the
         Holders acknowledge and agree that irreparable damage would occur in
         the event that any of the provisions of this Agreement or the Pledge
         Agreement were not performed in accordance with their specific terms or
         were otherwise breached. It is accordingly agreed that the parties

                                PLEDGE AGREEMENT

         PLEDGE AGREEMENT (this "PLEDGE AGREEMENT"), dated as of February ___,
2001, by and among SUNSHINE INTERNATIONAL MINING, INC., a Delaware corporation
(the "GRANTOR"), THE LIVERPOOL LIMITED PARTNERSHIP, a Bermuda limited
partnership ("TLLP"), ELLIOTT INTERNATIONAL, L.P., a Cayman Islands limited
partnership ("EILP", and together with TLLP, the "ELLIOTT HOLDERS"), STONEHILL
INSTITUTIONAL PARTNERS, L.P. ("SIP") and STONEHILL OFFSHORE PARTNERS, LIMITED
("SOPL" and together with SIP, the "STONEHILL HOLDERS") and WELLS FARGO BANK
MINNESOTA, N.A., as administrative and pledge agent (in such capacity, the
"PLEDGE AGENT") for the Elliott Holders and the Stonehill Holders (collectively,
the "Holders").

         WHEREAS, contemporaneously with the execution and delivery of this
Pledge Agreement, the Grantor and the Holders are entering into that certain
Call Option Agreement dated as of the date hereof (as amended, modified or
supplemented from time to time, the "CALL OPTION AGREEMENT");

         WHEREAS, unless otherwise defined herein, terms defined in the Call
Option Agreement are used herein as therein defined;

         WHEREAS, under the Call Option Agreement, as of the date hereof, the
Grantor shall issue a call option to each Holder (each a "CALL OPTION" and
collectively, the "CALL OPTIONS") to purchase, collectively, up to 100% of the
shares (the "SAI SHARES") of capital stock of Sunshine Argentina, Inc. ("SAI")
and grant to each Holder a first priority perfected security interest in such
shares therewith;

         WHEREAS, Schedule 1 to the Call Option Agreement sets forth among other
things, the maximum number of SAI Shares that each Holder may receive upon
exercise of its Call Option;

         WHEREAS, the Pledge Agent has been provided with a copy of, has
reviewed, is familiar with and understands the Call Option Agreement and
Schedule 1 thereto;

         WHEREAS, pursuant to the Call Option Agreement, the parties hereto
desire to more fully set forth their respective rights in connection with such
security interest and pledge; and

         NOW, THEREFORE, for good and valuable consideration, the Grantor hereby
agrees with the Holders as follows:

         SECTION 1. GRANT OF SECURITY AND PLEDGE.

         (a) The Grantor hereby transfers, grants, bargains, sells, conveys,
hypothecates, assigns, pledges and sets over to the Pledge Agent for the ratable
benefit of the Holders and

<PAGE>   21

hereby grants to the Pledge Agent for the ratable benefit of the Holders, a
perfected pledge and security interest in all of the Grantor's right, title and
interest in and to the Collateral, which pledge and security interest in the
Collateral securing the Call Option made under the Call Option Agreement shall
have first priority. For the purposes hereof, "COLLATERAL" shall mean:

                  (i) all SAI Shares, whether currently issued or issued in the
         future, and the certificates representing or evidencing all such shares
         (the "PLEDGED SHARES");

                  (ii) all other securities which may be delivered to and held
         by the Pledge Agent in respect of the Pledged Shares pursuant to the
         terms hereof;

                  (iii) all dividends, cash, instruments and other property from
         time to time received, receivable or otherwise distributed, in respect
         of, in exchange for or upon the conversion of the securities referred
         to in clauses (i) and (ii) above; and

                  (iv) all rights and privileges of each Grantor, as applicable,
         with respect to the securities and other property referred to in
         clauses (i), (ii) and (iii).

         (b) This Pledge Agreement and the Collateral secure the obligations of
the Grantor now or hereafter existing under the Call Option Agreement, and all
obligations of the Grantor now or hereafter existing under or in respect of this
Pledge Agreement (the "OBLIGATIONS").

         SECTION 2. DELIVERY OF COLLATERAL.

         (a) On the Closing Date (as defined in the Call Option Agreement), all
certificates or instruments representing or evidencing the Collateral shall be
delivered to and held by the Pledge Agent pursuant hereto and shall be
accompanied by duly executed instruments of transfer or assignment in blank
("BENEFICIAL OWNERSHIP"), all in form and substance satisfactory to the Pledge
Agent.

         (b) All Collateral hereinafter received by the Grantor shall be
received in trust for the benefit of the Holders, shall be segregated by the
Grantor from the other property or funds of the Grantor and shall be forthwith
delivered to the Pledge Agent to hold as Collateral.

         SECTION 3. VOTING AND OTHER RIGHTS

         (a) So long as the SAI Shares are Collateral under this Agreement, the
Pledge Agent shall be entitled to exercise any and all voting and other
consensual rights pertaining to the Collateral, or any part thereof, as
instructed by the Holders based upon each of their ratable interest in the SAI
Shares as set forth in Schedule 1 of the Call Option Agreement for any purpose
not inconsistent with the terms of this Pledge Agreement.

         (b) The Grantor shall execute and deliver (or cause to be executed and
delivered) to the Pledge Agent all such proxies and other instruments as the
Pledge Agent may reasonably request for the purpose of enabling the Pledge Agent
to exercise the voting and other rights which it is entitled to exercise per the
instructions of the Holders pursuant to Section 3(a) above.

                                       2
<PAGE>   22

         SECTION 4. DEFAULT ON OBLIGATIONS; EXERCISE OF CALL OPTION. In the
event that: (i) as a result of a failure by the Grantor to perform an
Obligation, the Call Options shall have become exercisable or (ii) the Call
Options shall otherwise have become exercisable, then:

         (a) Upon receipt of an Exercise Notice from a Holder, the Pledge Agent
shall take all steps necessary to prepare for the timely delivery to the
exercising Holder of the Call Amount (not to exceed the maximum number of SAI
Shares that the exercising Holder is entitled to receive as set forth on
Schedule 1). On the Purchase Date, the Pledge Agent shall deliver Beneficial
Ownership of such Call Amount and all other Collateral related thereto to such
Holder.

         (b) On the Purchase Date, all rights of the Pledge Agent to vote or
otherwise act on behalf of the Holder with respect to the transferred SAI Shares
(including, but not limited to, the right to exercise the voting and other
consensual rights which it would otherwise be entitled to exercise) shall cease
and all such rights shall thereupon become vested exclusively in the transferee,
who shall thereupon have the sole right to exercise such voting and other
consensual rights.

         SECTION 5. REPRESENTATIONS AND WARRANTIES. The Grantor hereby
represents and warrants that each of the representations and warranties
contained in the Call Option Agreement are true and accurate.

         SECTION 6. FURTHER ASSURANCES.

         (a) The Grantor agrees that from time to time, at the expense of the
Grantor, it will promptly execute and deliver all further instruments and
documents and take all further action that may be necessary or that the Pledge
Agent may reasonably request, in order to perfect and protect any security
interest granted or purported to be granted hereby or to enable the Pledge Agent
and/or the Holders to exercise and enforce any of its rights and remedies
hereunder with respect to any Collateral. Without limiting the generality of the
foregoing, the Grantor will execute and file such financing or continuation
statements or amendments thereto and such other instruments or notices as may be
necessary, or as the Pledge Agent may reasonably request, in order to perfect
and preserve the security interests granted or purported to be granted hereby.

         (b) The Grantor hereby authorizes the Pledge Agent to file one or more
financing or continuation statements, and amendments thereto, relative to all or
any part of the Collateral without the signature of the Grantor where permitted
by law.

         (c) Each Grantor will furnish to the Pledge Agent, from time to time,
statements and schedules further identifying and describing the Collateral and
such other reports in connection with the Collateral as the Pledge Agent may
reasonably request, all in reasonable detail.

         SECTION 7. OTHER TRANSFERS, LIENS; ADDITIONAL SHARES. Each Grantor
shall not:

         (a) Sell, assign (by operation of law or otherwise) or otherwise
dispose of any of the Collateral, except for dispositions otherwise permitted by
the Call Option Agreement.

                                       3
<PAGE>   23

         (b) Create or suffer to exist any lien, security interest or other
charge or encumbrance upon or with respect to any of the Collateral to secure
any obligation of any person or entity, except for the security interest created
by this Pledge Agreement, or except as otherwise expressly provided in the
Transaction Documents.

         (c) The Grantor agrees that it shall not cause SAI to issue any stock
or other securities in addition to or substitution for the SAI Shares and shall
pledge hereunder, immediately upon its acquisition (directly or indirectly)
thereof, any and all additional shares of stock or other securities of SAI or
the SAI Shares.

         SECTION 8. PLEDGE AGENT APPOINTED ATTORNEY-IN-FACT. The Grantor hereby
irrevocably appoints the Pledge Agent the Grantor's attorney-in-fact (which
appointment shall be irrevocable and deemed coupled with an interest), with full
authority in the place and stead of the Grantor and in the name of the Grantor
or otherwise, from time to time in the Pledge Agent's discretion to take any
action and to execute any instrument which the Pledge Agent may deem necessary
or advisable to accomplish the purposes of this Pledge Agreement, including,
without limitation:

         (a) to ask, demand, collect, sue for, recover, compound, receive and
give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral,

         (b) to receive, endorse, and collect any drafts or other instruments,
documents and chattel paper, in connection with clause (i) or (ii) above,

         (c) to receive, endorse and collect all instruments made payable to the
Grantor representing any dividend or other distribution in respect of the
Collateral or any part thereof and to give full discharge for the same, and

         (d) to file any claims or take any action or institute any proceedings
which the Pledge Agent may deem necessary or desirable for the collection of any
of the Collateral or otherwise to enforce the rights of the Pledge Agent with
respect to any of the Collateral.

         SECTION 9. PLEDGE AGENT MAY PERFORM. If the Grantor fails to perform
any Obligation contained herein, the Pledge Agent may itself perform, or cause
performance of, such agreement, and the expenses of the Pledge Agent incurred in
connection therewith shall be payable by the Grantor under Section 11(b).

         SECTION 10. AGREEMENT. The Grantor, the Holders and the Pledge Agent,
by execution and delivery of this Agreement, each agree to act with respect to
the Collateral and each other in accordance herewith and in the Call Option
Agreement. The Pledge Agent, by its execution and delivery of this Agreement,
hereby agrees to accept receipt of the Collateral and agrees to act with respect
thereto as set forth herein and in accordance with the Call Option Agreement.

         (a) The Grantor agrees to indemnify the Pledge Agent from and against
any and all claims, losses and liabilities growing out of or resulting from this
Pledge Agreement (including, without limitation, enforcement of this Pledge
Agreement), except claims, losses or liabilities directly arising from the
Pledge Agent's own gross negligence, willful misconduct or bad faith.

         (b) The Grantor will upon demand pay to the Pledge Agent the amount of

         (c) The Grantor agrees that the Pledge Agent does not assume, and shall
have no responsibility for, the payment of any sums due or to become due under
any agreement or contract other than included in the Collateral or the
performance of any obligations to be performed under or with respect to any such
agreement or contract by any of the Grantor, and except as the same may have
resulted from the gross negligence or willful misconduct of the Pledge Agent,
the Grantor hereby agrees to indemnify and hold the Pledge Agent harmless with
respect to any and all claims by any person relating thereto.

         SECTION 12. SECURITY INTEREST ABSOLUTE. All rights of the Pledge Agent
and security interests hereunder, and all obligations of the Grantor hereunder,

might constitute a defense available to, or a discharge of, any guarantor or
other obligator in respect of its Obligations.

         SECTION 13. AMENDMENTS; ETC. No amendment or waiver of any provision of
this Pledge Agreement, nor any consent to any departure by the Grantor herefrom,
