                                     GENERAL


1.       General information.

         (a)      Form of organization. Both Sunshine Mining and Refining
                  Company ("SSC") and Sunshine Precious Metals, Inc. ("Company"
                  and, together with SSC, the ("Applicants")) are corporations.

         (b)      State or other sovereign power under the laws of which
                  organized. SSC is organized under the laws of the State of
                  Delaware. The Company is organized under the laws of the State
                  of Delaware.

2.       Securities Act exemption applicable.

         The Applicants are relying upon the exemption provided by Section
3(a)(9) of the Securities Act of 1933, as amended (the "Securities Act"), in
claiming that registration of the securities to be issued in connection with the
recapitalization of SSC (the "Recapitalization"), as described below, is not
required under the Securities Act. The Recapitalization contemplates, among
other things, (i) certain amendments to the Terms and Conditions (the "Terms
Amendment") of the 8% Senior Exchangeable Notes due 2000 of the Company and
guaranteed by SSC (the "Notes") as provided in an Extraordinary Resolution
proposed to be adopted by the holders of the Notes (the "Noteholders") and (ii)
certain amendments to that certain Trust Deed, dated March 21, 1996 (as amended
and supplemented, the "Trust Deed"), among SSC, the Company, and HSBC Bank USA
(formerly Marine Midland Bank) (the "Trustee"), as trustee for the holders of
the Notes, pursuant to the provisions of that certain First Supplement to the
Trust Deed (the "First Supplement"). Because the Recapitalization is being
conducted by SSC with respect to its existing security holders exclusively, the
transaction is exempt from registration pursuant to Section 3(a)(9) of the
Securities Act.

         There have not been, and there will not be, any sales of the Notes made
by the Applicants or by or through an underwriter at or about the same time as
the Recapitalization. No consideration has been or is to be given, directly or
indirectly, to any person in connection with the transaction, except for
customary payments to be made in respect of preparation, printing and mailing of
the notice with respect to the meeting of the Noteholders with respect to the
approval of the Extraordinary Resolution and related documents. In addition, the
Applicants will pay remuneration to their financial, legal, and accounting
counsel for the provision of advisory, legal, and accountancy services,
respectively.

                           all other matters submitted to a vote of
                           stockholders. Holders of SSC's common stock are not
                           entitled to cumulate their votes for the election of
                           directors. Holders of SSC's common stock are not
                           entitled to preemptive rights. In order to approve
                           any business combination, including any merger or
                           consolidation or the sale, lease, exchange or other
                           disposition of all or substantially all of our
                           assets, including a disposition in connection with a
                           dissolution or winding up or liquidation, Article
                           Five of SSC's Certificate of Incorporation requires
                           the affirmative vote or consent of the holders of:
                           (i) a majority of the shares entitled to vote on the
                           business combination, and (ii) a majority of any
                           series or class of preferred stock entitled to vote
                           as a class on the business combination. Article Five
                           may not be amended or repealed without the prior
                           affirmative vote or consent of the holders of: (i) 66
                           2/3% of all shares of stock entitled to vote on the
                           amendment or repeal, and (ii) 66 2/3% of any series
                           or class of preferred stock, if the Board of
                           Directors gives such series or class of preferred
                           stock such right to vote as a class. These provisions
                           may have the effect of delaying, deterring or
                           preventing a change of control of our corporation.

                  (ii)     Holders of the Company's common stock are entitled to
                           cast one vote for each share held of record on all
                           matters submitted to a vote of shareholders.

this application shall have the meanings given to such terms in the Trust Deed.

         (A)      Events of Default; Withholding of Notice.

         The Trustee at its discretion may, and if so requested in writing by
the holders of at least one-quarter in principal amount of the Notes then
outstanding or if so directed by an Extraordinary Resolution of the Noteholders
shall, give notice to the Company that the Notes are, and they shall accordingly
thereby forthwith become, immediately due and repayable at their principal
amount together with accrued interest (as provided in the Trust Deed) if any of
the following events (each an "Event of Default") shall have occurred (unless
(i)

such events (including, without limitation, the Merger) are expressly permitted
or contemplated by the Trust Deed or (ii) such Event of Default has been
remedied to the satisfaction of the Trustee):

         (1) if default is made for a period of 5 Business Days or more in the
payment of any principal or interest due in respect of the Notes or any of them;
or

         (2) if the Company or SSC fails to perform or observe any of its other
obligations, covenants, conditions or provisions under the Notes or the Trust
Deed and (except where the Trustee shall have certified to the Company in
writing that it considers such failure to be incapable of remedy in which case
no such notice or continuation as is hereinafter mentioned will be required)
such failure continues for the period of 30 calendar days (or such longer period
as the Trustee may in its absolute discretion permit) next following the service
by the Trustee on the Company or SSC, as the case may be, of notice requiring
the same to be remedied; or

         (3) if (i) any other Indebtedness of the Company, SSC or any Principal
Subsidiary becomes due and repayable prior to its stated maturity by reason of
an event of default (howsoever described) or (ii) any such Indebtedness is not
paid when due or, as the case may be, within any applicable grace period (as
originally provided) or (iii) the Company, SSC or any Principal Subsidiary fails
to pay when due (or, as the case may be, within any originally applicable grace
period) any amount payable by it under any present or future guarantee for, or

         (10) if there is any final judgment or judgments for the payment of
money exceeding in the aggregate $1,000,000 outstanding against The Company, SSC
or any Principal Subsidiary which has been outstanding for more than sixty (60)
calendar days from the date of its entry and shall not have otherwise been

         The Trustee may agree, without the consent of the Noteholders or
Couponholders to any modification (subject to certain exceptions) of, or to the
waiver or authorization of any breach or proposed breach of, any of the
Conditions or any of the provisions of the Trust Deed which is not, in the
opinion of the Trustee, materially prejudicial to the interests of the
Noteholders or Couponholders or to any modification which is of a formal, minor
or technical nature or to correct a manifest error.

         If it is proved that, as regards any specified Note or Coupon, The
Company has made default in paying any sum due to the relevant Noteholder or
Couponholder, such proof will (unless the contrary be proved) be sufficient
evidence that the same default has been made as regards all other Notes or (as
the case may be) Coupons which are then payable.

         The Trustee may at any time, at its discretion and with prior written
notice to The Company and SSC, take such proceedings against The Company or SSC
as it may think fit to enforce the provisions of the Trust Deed, the Notes and
the Coupons or the Guarantee but it shall not be bound to take any proceedings
or any



                                       8

other action in relation to the Trust Deed, the Notes or the Coupons or the
Guarantee unless (a) it shall have been so directed by an Extraordinary
Resolution of the Noteholders or so requested in writing by the holders of at
least one-quarter in principal amount of the Notes then outstanding, and (b) it
shall have been indemnified to its satisfaction. No Noteholder or Couponholder
shall be entitled to proceed directly against The Company unless the Trustee,
having become bound so to proceed, fails to do so within a reasonable period and
such failure shall be continuing.

         Notices to holders of Registered Notes will be mailed to them at the
respective addresses in the Register and deemed to have been given on the fourth
Business Day after the date of mailing, provided that, if at any time by reason
of suspension or curtailment (or except suspension or curtailment) of postal
services within the U.S. or elsewhere The Company is unable effectively to give
notice to holders of Registered Notes through the post, notices to holders of
Registered Notes will be valid if given in the same manner as other notices as
set forth below.

         Notices to all the Noteholders will be valid if published in a leading
English language daily newspaper published in London or such other English
language daily newspaper with general circulation in Europe as the Trustee may
approve (which is expected to be the Financial Times) and, so long as the Notes
are listed on the Luxembourg Stock Exchange and the rules of that Exchange
require, in a leading newspaper having general circulation in Luxembourg (which
is expected to be the Luxembourg Wort). Any notice shall be deemed to have been
given on the date of publication or, if so published more than once, on the date
of the first publication. If publication as provided above is not practicable,
notice will be given in such other manner, and shall be deemed to have been
given on such date, as the Trustee may approve. Couponholders will be deemed for
all purposes to have notice of the contents of any notice given to the
Noteholders in accordance with the above-described condition.

         Any modification, waiver or authorization will be binding on the
Noteholders and the Couponholders and, unless the Trustee agrees otherwise, any
modification shall be notified by The Company to the Noteholders as soon as
practicable thereafter with the above-described provisions.

                  limited to repossession or sale of such property, (vi) for

                  consolidated basis, in respect of all such obligations, not to

attached on issue as set out in the Global Bearer Note. Pending exchange of the
Global Bearer Note, its holder will, subject to its provisions, be deemed to be
the holder of the definitive Bearer Notes and the Coupons for all purposes save
that unless, upon due presentation of the Global Note for exchange, delivery of
Bearer Notes is improperly refused or withheld and such refusal or withholding
is continuing at the relevant time, the Global Bearer Note will not confer upon
its holder the right to receive interest or to exercise the Exchange Rights.

         The Bearer Notes and the Coupons will be security printed in accordance
with the applicable stock exchange requirements and the Bearer Notes, Coupons,
Registered Notes and Global Bearer Note will be in or substantially in the

Agent. The Registered Notes will be signed manually or in facsimile by a duly
authorized officer executed under the Common Seal of The Company and will be
authenticated by the Registrar. The Company may use the facsimile signature of
any person who is at the date of this Trust Deed a duly authorized officer of
The Company even if at the time of issue of any Notes and/or Coupons he no
longer holds such office. None of the Global Bearer Note, the Notes or the
Coupons shall be valid for any purpose unless and until so authenticated (if
applicable) and executed.

         All moneys received by the Trustee in respect of the Notes or amounts
payable under the Trust Deed will, regardless of any appropriation of all or
part of them by The Company, be held by the Trustee upon trust to apply them in
accordance with the provisions of the Notes and the Trust Deed:

         first, in payment of all costs, charges, expenses and liabilities
         properly incurred by the Trustee (including remuneration payable to the
         Trustee) in carrying out its functions under the Trust Deed;

         secondly, in payment of any principal and interest and all other sums
         owing in respect of the Notes and the Coupons pari passu and rateably;
         and

         thirdly, in payment of the balance (if any) to The Company for itself.

Without prejudice to the foregoing, if the Trustee holds any moneys which
represent principal or interest or other sums in respect of Notes or Coupons
which have become void or in respect of which claims have become prescribed
under Condition 12 of the Trust Deed, the Trustee will hold such moneys upon the
above trusts.

         (C)      Release and Substitution of Property Subject to the Lien of
                  the Indenture. Not applicable.

         (D)      Satisfaction and Discharge of the Indenture.

         The Trust Deed shall cease and be of no further effect and the Trustee
shall, upon the request and cost of The Company, execute proper documents
acknowledging the termination, satisfaction and discharge of the Trust Deed,
when none of the Notes are Outstanding.

         (E)      Evidence as to Compliance.

         The Company will, and SSC will procure that The Company will, send to
the Trustee, within 14 days after its annual audited consolidated balance sheet
and profit and loss account being made available to its members, and also within
14 days after any request by the Trustee of a certificate signed by two duly
authorized officers of The Company on behalf of The Company to the effect that,
having made all reasonable inquiries, to the best of the knowledge, information
and belief of The Company as at a date (the "Certification Date") being not more
than five days before the date of the certificate no Event of Default had
occurred since the date of the Trust Deed or the Certification Date of the last

it together with a list of Subsidiaries which are Principal Subsidiaries of The
Company and details of its Consolidated Net Worth as at the date of such
certificate.

     Notes as follows:

     (i)  If and whenever there shall be an alteration to the number of the
          Shares as a result of consolidation, reclassification or subdivision
          of the Shares, the Exchange Price shall be adjusted by multiplying the
          Exchange Price in force immediately before such alteration by the
          following fraction:-

                                        A
                                        -
                                        B

     where:

     A    is the number of Shares in issue immediately after such alteration;
          and

     B    is the number of Shares in issue immediately before such alteration.

     Such adjustment shall become effective on the date the alteration takes
     effect.

           way of rights, or shall issue or grant to Shareholders as a class by
           way of rights securities (including options, warrants and other
           rights) carrying rights to subscribe for or purchase any Shares, in

           Price per Share on the dealing day last preceding the date on which
           the terms of such issue or grant are publicly announced, the Exchange
           Price shall be adjusted by multiplying the Exchange Price in force

           Current Market Price per Share; and

     C     is the number of Shares so issued or such maximum number of Shares.

     Such adjustment shall become effective on the date of such issue or grant.

           any securities, options, warrants or other rights referred to in
           paragraph (iii) of this Clause 8(B)) to Shareholders as a class by

     where:

     A    is the Current Market Price per Share on the dealing day last
          preceding, the date on which the terms of such issue or grant are
          publicly announced; and

     B    is the fair market value on the date of such announcement, as
          determine in good faith by a merchant bank in London of international
          repute acting as an expert, appointed by SSC and approved in writing
          by the Trustee or, in default of such appointment or in the absence of
          such, approval, appointed by the Trustee, of the portion of the rights
          attributable to one Share.

     Such adjustment shall become effective on the date of such issue or grant.

     (v)  If and whenever SSC or (at the direction or request of or pursuant to

          than the Notes but including options, warrants and other rights)
          carrying rights of conversion into, or exchange or subscription for,
          Shares, or securities which by their terms might be redesignated as
          Shares or so as to carry rights of conversion into, or exchange or
          subscription for Shares, where the consideration per Share receivable
          upon exercise of such rights or upon such redesignation is less than
          the Current Market Price per Share on the dealing day last preceding
          the date on which the terms of such issue or grant are publicly
          announced, the Exchange Price shall be adjusted by multiplying the
          Exchange Price in force immediately before such issue or grant by the
          following fraction:

                                     A + B
                                     -----

          for the maximum number of Shams to be issued upon exercise in full of
          such rights, or arising from such redesignation, would purchase at
          such Current Market Price per Share; and

     C    is the maximum number of Shares to be issued upon exercise in full of
          such rights at the initial conversion, exchange or subscription price
          or rate or to arise upon such redesignation.

     Such adjustment shall become effective on the date of such issue or grant.

          (vi) If SSC (after consultation with the Trustee) or the Trustee
               (after consultation with SSC determines that an adjustment should
               be made to the Exchange Price as a result of one or more events
               or circumstances not referred to in paragraphs (i) to (v) of this
               Clause 8(B) (even if the relevant event or circumstance is
               specifically excluded from the operation of those paragraphs or
               any of them) SSC, shall, at its own expense and acting
               reasonably, request the Auditors, acting as experts, to determine
               as soon as practicable what adjustment (if any) to the Exchange
               Price is fair and reasonable to take account of such event or
               circumstance and the date on which such adjustment should take
               effect, and upon such determination such adjustment (if any)
               shall be made and shall take effect in accordance with such
               determination, but so that an adjustment shall only be made
               pursuant to this sub-paragraph (vi) if the Auditors are so
               requested to make such a determination not more than 21 days
               after the occurrence of the relevant event or circumstance.

          Provided that where the circumstances giving rise to any adjustment
          pursuant to this Clause 8(B) have already resulted or will result in
          an adjustment to the Exchange Price or where the circumstances giving
          rise to any adjustment arise by virtue of any other circumstances
          which have already given or will give rise to an adjustment to the
          Exchange Price, such modification (if any) shall be made to the
          operation of the provisions of this Clause 8(B) as may be advised by
          the Auditors, acting as experts, to be in their opinion appropriate in
          order to give the intended effect.

     (C)  Calculation of consideration receivable: For the purpose of any
          calculation of the consideration receivable pursuant to paragraphs
          (iii) and (v) of Clause 8(B), the following provisions shall apply:-

          (i)  the aggregate consideration receivable for Shares issued for cash
               shall be the amount of such cash received or receivable by SSC,
               provided that in no case shall any deduction be made for any
               commission or any expenses paid or incurred by SSC for any
               underwriting of the issue or otherwise in connection therewith;

                                       16

          (ii)  the aggregate consideration receivable for Shares to be issued
                upon the exercise of rights of exchange or subscription shall be
                the consideration received or receivable by SSC which is
                attributed by SSC to such rights or, if no part of such
                consideration is so attributed or the Trustee so requires by
                notice in writing to SSC, the fair market value of such rights
                as at the date on which the terms of issue of the relevant
                securities (including options, warrants and other rights) are
                publicly announced (as determined in good faith by an
                independent merchant bank in London of international repute,
                acting as an expert, appointed by SSC, and approved in writing
                by the Trustee or, in default of such appointment or in the
                absence of such approval, appointed by the Trustee) plus the
                additional consideration to be received by SSC as a consequence
                of such exercise, such additional consideration to be the amount
                (including any premium) to be treated by SSC as paid up on the
                Shares or other securities arising from such exercise (the
                consideration in all such cases to be determined subject to the
                proviso in paragraph (i) of this Clause 8(C); and

          (iii) the consideration per Share receivable upon the exercise of
                rights, exchange or subscription shall be the aggregate
                consideration referred to in paragraph (ii) of this Clause 8(C),
                converted into Dollars if such consideration is expressed in a
                currency other than Dollars at such rate of exchange as may be
                determined in good faith by an independent merchant bank in
                London of international repute, acting as an expert, appointed
                by SSC and approved in writing by the Trustee or, in default of
                such appointment or in the absence of such approval, appointed
                by the Trustee, to be the spot rate ruling at the close of
                business on the date on which the terms of issue of the relevant
                securities (including options, warrants and other rights) are
                publicly announced, divided by the number of Shares to be issued
                upon such exercise at the initial conversion, exchange or
                subscription price or rate.

     (D)  Post-record date adjustments: If the Exchange Date in relation to any
          Note shall be after the record date for any such issue, grant or offer
          as is mentioned in Clause 8(B), but before the relevant adjustment
          becomes effective under Clause 8(B), SSC shall (conditional upon such
          adjustment becoming effective) procure that there shall be issued to
          the exchanging Noteholder or in accordance with the instructions
          contained in the Exchange Notice (subject to any applicable exchange
          control or other laws or other regulations) such additional number of
          Shares as, together with the Shares issued or to be issued on exchange
          of the relevant Note, is equal to the number of Shares which would
          have been required to be issued on exchange of such Note if the
          relevant adjustment (more particularly referred to in such paragraphs)
          to the Exchange Price had in fact been made and become effective
          immediately after the relevant record date. Such additional Shares
          will be allotted as at, and within one month after, the relevant
          Exchange Date or of the date of issue of Shares if adjustment results
          from the issue of Shares and certificates for such Shares (if the
          Shares are in certificated form as defined in Clause 10) will be
          despatched within such period of one month.

(E)  No adjustment

     Notwithstanding the provisions of this clause 8 the Exchange Price will
     not, be (i) adjusted by reason of the Merger other than pursuant to the
     provisions of Condition 8(A)(iv) or (ii) reduced as a result of any such
     adjustment, and the Company covenants not to take any action, if, after
     giving effect thereto, the Exchange Price would be reduced to such an
     extent that, under applicable law then in effect, Notes may not be
     exchanged at such reduced Exchange Price for legally issued, fully paid and
     non-assessable Shares. No adjustment will be made where such adjustment
     would be less than 5 percent of the Exchange Price then in effect. Any
     adjustment not so made will be carried forward and taken into account in
     any subsequent adjustment. On any adjustment, the resultant Exchange Price,
     if not an integral multiple of one cent shall be rounded down to the
     nearest one cent.

(F)  The Company shall give sufficient notice to the Trustee to enable it to
     comply with its obligation under Condition 8(A)(iv) to give notice to the
     Noteholders of any reset of the Exchange Price pursuant to Condition 17.

9    Exchange on redemption and mandatory exchange

(A)  (i)  Exchange by Trustee: The Trustee may, at its absolute discretion and
          without any responsibility for any loss occasioned thereby, within the
          period commencing on the date six Business Days prior to, and ending
          at the close of business in New York prior to the date fixed for
          redemption from time to time of any of the Notes (including any
          redemption under Condition 9(A), (B) or (C) but subject as aforesaid),
          elect by notice in writing to the Company and SSC to exchange the
          aggregate number of Notes due for redemption on such date fixed for
          redemption and in respect of which Exchange Rights have not been
          exercised by Noteholders ("Unexercised Notes") into Shares at the
          Exchange Price applicable at such redemption date if all necessary
          consents (if any) have been obtained and the Trustee is satisfied or
          is advised by an independent merchant bank that the net proceeds of an
          immediate sale of the Shares arising from such exchange, disregarding
          any liability (other than a liability of the Trustee) to taxation or
          the payment of any capital, stamp, issue or registration duties
          consequent thereon, would be likely to exceed by 5 percent or more the
          amount of redemption moneys and interest which would otherwise be
          payable in respect of interest accrued since the Interest Payment Date
          last immediately preceding such redemption date or, if such date falls
          on or before the first Interest Payment Date, since the Closing Date
          in respect of such Unexercised Notes.

     (ii) Allotment of Shares to Trustee: SSC undertakes to allot, within 10
          Business Days after the relevant date fixed for redemption, to the
          Trustee on behalf of the holders of the Unexercised Notes so exchanged
          as of the relevant redemption

                                       18

<PAGE>   22


           date the Shares required to be allotted pursuant to Clause 9(A) and
           to deliver, within 15 Business Days after such Shares, in New York to
           the Trustee.

     (iii) Sale of Shares by Trustee: The Trustee shall, subject to applicable
           law, on behalf of the holders of the Unexercised Notes, arrange for
           the sale of the Shares issued on such exchange of the Unexercised
           Notes as soon as practicable and (subject to any necessary consents
           being obtained and to the deduction by the Trustee of any amount
           which it determines to be payable in respect of its liability to
           taxation and the payment of any capital, stamp, issue or registration
           duties (if any) and any costs incurred by the Trustee in connection
           with that allotment and sale thereof) the net proceeds of sale
           together with accrued interest payable under Condition 8(B)(iv) (if
           any) in respect of such Unexercised Notes (if any) shall be held by
           the Trustee and distributed rateably to the holders of such
           Unexercised Notes against due presentation of such Unexercised Notes
           in accordance with Condition 7. The amount of such net proceeds of
           sale shall be treated for all purposes as the full amount due by the
           Company in respect of the Unexercised Notes (for this purpose
           treating any Coupon expressed to be payable on the date fixed for
           redemption of such Notes as an unmatured Coupon).

(B)  (i)   In the event the Company elects to exercise its right of mandatory
           exchange under Condition 8(E)(i) the Company shall, not less than 30
           and not more than 60 calendar days prior to the Mandatory Exchange
           Date, cause written notice of the Mandatory Exchange Date to be given
           to the Trustee, the Paying Agents, the Exchange Agents and the
           holders of the Notes (in accordance with Condition 17 (such notice to
           include a statement of the consequences of failure on the part of the
           Noteholders to perform the obligations specified in Condition 8(E)).
           Following such notice, each of the Noteholders will be required on or
           before the Mandatory Exchange Date to deliver or procure delivery of
           its Notes together with a duly completed Exchange Notice to the
           specified office of any Exchange Agent, during its usual business
           hours for such purposes and perform together with the Company and
           SSC, the obligations applicable to it on exchange specified in
           Condition 8.

     (ii)  If any Noteholder with respect to whose Notes mandatory exchange
           (pursuant to Condition 8) is to take place shall fail to perform its
           obligations specified in Condition 8 or shall have a registered
           address in any territory where, in the absence of any registration
           statement or other special formalities or legal requirements, the
           issue, allotment, transfer or delivery of the Shares arising on
           mandatory exchange in the reasonable opinion of the Trustee, is or
           could be

                                       19

<PAGE>   23


           unlawful or impracticable, subject to applicable law, the Trustee
           shall make arrangements for the sale of such Shares to a third party
           at the best consideration reasonably obtainable by the Trustee and
           pay to such Noteholder the consideration received by the Trustee in
           respect of such Shares (after any deduction required to reimburse any
           reasonable and proper expenses incurred in arranging any such sale or
           any taxes payable in connection therewith arising solely as a result
           of the Noteholder's failure to perform its obligations under
           Condition 8(E)).

10   Covenants relating to exchange

(A)  SSC hereby undertakes to and covenants with the Trustee that so long as any
     Exchange Right remain exercisable, it will, save with the approval of an
     Extraordinary Resolution or with the prior written approval of the Trustee
     where, in the Trustee's opinion, it is not materially prejudicial to the
     interests of the Noteholders to give such approval:-

     (i)   Issue and ensure sufficient share capital: issue Shares to
           Noteholders on the exercise of Exchange Rights in accordance with the
           Conditions and at all times keep available for issue free from
           pre-emptive rights out of its authorized but unissued capital such
           number of Shares as would enable the Exchange Rights and all other
           rights of subscription and exchange for and exchange into Shares to
           be satisfied in full;

     (ii)  Limited modification of rights: not in any way modify the rights
           attaching to the Shares with respect to voting, dividends or
           liquidation nor issue any other class of equity share capital
           carrying any rights which are more favorable than the rights
           attaching to the Shares;

     (iii) Restricted action: not make any issue, grant or distribution or take
           any other action if the effect thereof would be that, on the exchange
           of Notes, Shares would have to be issued at a discount or otherwise
           could not, under any applicable law then in effect, be legally issued
           as fully paid;

     (iv)  Notice of adjustment to Exchange Price: simultaneously with the

     conveyed by such means even if it contains some error or is not authentic.

(B)  Trustee to assume due performance: The Trustee need not notify anyone of
     the execution of this Trust Deed or do anything to ascertain whether any
     Event of Default has occurred and, until it has actual written knowledge to
     the contrary, the Trustee may assume that no such event has occurred.

(C)  Resolutions of Noteholders: The Trustee will not be responsible for having
     acted in good faith upon a resolution purporting to have been passed at a
     meeting of Noteholders in respect of which minutes have been made and
     signed even though it may later be found that there was a defect in the
     constitution of such meeting or the passing of such resolution or that such
     resolution was not valid or binding upon the Noteholders or the
     Couponholders.

(D)  Officers' certificate: The Trustee may call for and may accept as
     sufficient evidence of any fact or matter or of the expediency of any act a
     certificate signed by any two authorized officers of the Company or SSC on
     behalf of the Company or SSC (including any calculation of the Consolidated
     Net Worth of SSC) as to any fact or matter upon which the Trustee may, in

     information to the effect that, in the opinion of the persons so
     certifying, any particular act is expedient and the Trustee need not call

     occasioned by it failing to do so or by it acting or not acting on any such
     certificate.

     with the performance of the duties of the Trustee hereunder or thereunder
     or unless it comprises the holding or placing of such documents in the
     United Kingdom, the Trustee may not take any such action if a liability to
     stamp duty or other duties or taxes would thereby arise.

(F)  Discretion of Trustee: Save as expressly provided in this Trust Deed, the
     Trustee will have absolute and uncontrolled discretion as to the exercise
     of its functions and will not be

                                       26

<PAGE>   30
     responsible for any loss, liability, cost, claim, action, demand, expenses
     or inconvenience which may result from their exercise or non-exercise.

(G)  Delegation: Whenever it considers it expedient in the best interests of the
     Noteholders the Trustee may delegate to any person and on any terms

     supervise such delegate or be responsible for any loss, liability, cost,
     claim, action, demand or expense incurred by reason of any misconduct or
     default by any such delegate or sub-delegate. Notwithstanding the general
     power of delegation in this Clause 13(G) the Trustee may not delegate the
     right to give any notice under Condition 13 that the Notes are immediately
     due and repayable unless prior to such delegation the Trustee provides to

     advised by its legal advisers that it should delegate that right (with or
     without any other rights, trusts, powers, authorities and discretions) to
     another person or fluctuating body of persons because of the conflict of
     interest or possible conflict of interest and/or other similar
     circumstances which the Trustee might face, or be subjected to, as the
     Trustee of this Trust Deed if it were not to delegate that right.

     Noteholder or Couponholder by reason of having accepted as valid or not
     having rejected any Note or Coupon purporting to be such and later found to
     be forged or not authentic.

(I)  Confidentiality: Unless ordered to do so by a court of competent
     jurisdiction, the Trustee shall not be required to disclose to any
     Noteholder or Couponholder any confidential financial, price sensitive or
     other information made available to the Trustee by the Company or SSC and
     no Noteholder or Couponholder shall be entitled to take any action to
     obtain from the Trustee any such information.

(J)  Determinations conclusive: As between itself and the Noteholders and
     Couponholders the Trustee may determine all questions and doubts arising in
     relation to any of the provisions of this Trust Deed. Every such
     determination, whether made upon such a question actually raised or implied
     in the acts or proceedings of the Trustee, will be conclusive in the
     absence of manifest error and shall bind the Trustee, the Noteholders and
     the Couponholders.

     necessary or desirable to convert any sum from one currency to another, it

     and date so specified will be binding on the Company, SSC, the Noteholders
     and the Couponholders.

(L)  Events of default: The Trustee may determine whether or not a default in
     the performance or observance by the Company or SSC of any obligation is in
     its opinion capable of remedy and/or whether or not any event is in its
     opinion materially prejudicial to the interests of the Noteholders or has a
     material adverse effect on the Company's or SSC's ability to perform or
     comply with any of its obligations under this Trust Deed, the Notes or the
     Coupons. Any such determination will be conclusive and binding upon the
     Company, SSC, the Noteholders and the Couponholders.

(M)  Payment for and delivery of Notes: The Trustee will not be responsible for
     the receipt or application by the Company of the proceeds of the issue of
     the Notes, the exchange of the Global Bearer Note for the definitive Notes
     or the delivery of definitive Notes to the persons entitled to them.

(N)  Notes held by the Company etc.: In the absence of actual knowledge in

     trusts, authorities or discretions (including, but not limited to, those in
     relation to any proposed modification, waiver or authorization of any
     breach or proposed breach of any of the Conditions or any of the provisions
     of this Trust Deed or any proposed substitution in accordance with Clause
     17(B) or 17(C) or any modification made pursuant to Clause 17(A)), the
     Trustee shall have regard to the interests of the Noteholders as a class
     and in particular, but without limitation, shall not have regard to the
     consequences of such exercise for individual Noteholders or Couponholders
     resulting from their being for any purpose domiciled or resident in, or
     otherwise connected with, or subject to the jurisdiction of, any particular
     territory and the Trustee shall not be entitled to require, nor shall any
     Noteholder or Couponholder be entitled to claim from the Company, SSC or
     the Trustee or any other person, any indemnification or payment of any tax
     arising in consequence of any such exercise upon individual Noteholders or
     Couponholders except to the extent provided for in Condition 10 and/or in
     any undertakings given in addition thereto or in substitution therefor
     pursuant to this Trust Deed.

(P)  No responsibility for values etc.: The Trustee shall not at any time be
     under any duty or responsibility to any Noteholders to determine whether
     any facts exist which may require any adjustment to the Exchange Price or
     with respect to the nature or extent of any such adjustment when made, or
     with respect to the method employed, or in this Trust Deed provided to be
     employed, in making the same. The Trustee shall not at any time be under
     any duty or responsibility in respect of the validity or value (or the kind

                                       28

     or amount) of any Shares or of any other securities, property or cash,
     which may at any time be made available or delivered upon the conversion of
     any Note, and it makes no representation with respect thereto. The Trustee
     shall not be responsible for any failure of the Company to make available
     or deliver any Shares or share certificates or other securities or property
     or make any payment upon the exercise of the Exchange Right in respect of
     any Note or of the Company to comply with any of the provisions contained
     in this Trust Deed.

     failed to show the degree of care and diligence required of it as trustee

     Coupon the Company made default in paying any sum due to the relevant
     Noteholders or Couponholder, such proof will (unless the contrary be

     payable.

               terms corresponding to the terms of Condition 10 with the
               substitution for the references in that Condition to the
               Company's Territory of references to the Substituted Territory

               be read accordingly;

<PAGE>   34


          (c)  if any two authorized officers of the Substituted Obligor certify
               on behalf of the Substituted Obligor that it will be solvent
               immediately after such substitution, the Trustee need not have

          (d)  the Company and the Substituted Obligor comply with such other

          the consent of the Noteholders and the Couponholders, to a change of
          law governing the Notes, the Coupons and/or the Trust Deed provided
          that such change would not, in the opinion of the Trustee, be
          materially prejudicial to the interests of the Noteholders.

     (2)  Release of substituted company: Any such agreement by the Trustee
          pursuant to this Clause 17(B) will, if so expressed, operate to
          release the Company (or any such previously substituted company under
          this Clause 17(B)) from any or all of its obligations under this Trust
          Deed, the Notes and the Coupons. Not later than 14 days after the
          execution of any such documents and after compliance with such
          requirements, notice of the substitution will be given by the Company

          Couponholders, but so as to bind the Noteholders and the
          Couponholders, agree with the Company and SSC to the substitution of
          any Subsidiary or holding company of SSC or any subsidiary of such
          holding company (the "Substituted Guarantor") in place of SSC (or of
          any previous substitute under this Clause 17(B)) as the

          guarantor of the obligations of the Company (or any previous
          substitute under Clause 17(C) under these presents guaranteed by SSC
          (or if any previous substitute under this Clause 17(C) under these
          presents, provided that:

          (i)    the Trustee is satisfied that such substitution is not
                 materially prejudicial to the interests of the Noteholders;

          (ii)   a trust deed is executed or some other form of undertaking is

                 the provisions of this Trust Deed, the Notes and the Coupons
                 binding on SSC with any consequential amendments which the
                 Trustee may deem appropriate as fully as if the Substituted
                 Guarantor had been named in these presents as the guarantor of
                 such obligations of the Company (or of any previous substitute
                 under Clause 17(B)) in place of SSC (or of any previous
                 substitute under this Clause 17(C);

          (iii)  where the Substituted Guarantor is subject generally to the
                 taxing jurisdiction of any territory or any authority of or in
                 that territory having power to tax (for the purpose of this
                 Clause 17(C), the "SUBSTITUTED TERRITORY") other than the
                 taxing jurisdiction of any territory to which (or to any
                 authority of or in which) SSC (or any previous substitute under
                 this Clause 17(C) is subject generally (for the purpose of this
                 Clause 17(C), the "EXISTING TERRITORY"), the Substituted
                 Guarantor will (unless the Trustee otherwise agrees) give to
                 the Trustee an undertaking in form and manner satisfactory to
                 the Trustee in term corresponding to the terms of Condition 10
                 with the substitution for the references in that Condition to
                 the Existing Territory of references to the Substituted
                 Territory and in such event this Trust Deed, the Notes and the
                 Coupons will be read accordingly;

          (iv)   if any two authorized officers of the Substituted Guarantor
                 certify on behalf of the Substituted Guarantor to the Trustee
                 that it will be solvent immediately after such substitution,
                 the Trustee need not have regard to the financial condition,
                 profits or prospects of the Substituted Guarantor or compare
                 them with those of SSC (or of any previous substitute under
                 this Clause 17(C)); and

          (v)    the Company (and any previous substitute under Clause 17(B)),

                 under this Clause 17(C)) comply with such other requirements
                 as the Trustee may direct in the interests of the Noteholders.

                                       32

<PAGE>   36


                 In the case of such substitution, the Trustee may agree,
                 without the consent of the Noteholders or the Couponholders, to
                 a change of law governing these presents provided that such
                 change would not, in the opinion of the Trustee, be materially
                 prejudicial to the interests of the Noteholders. Any such
                 substitution as is permitted by this Clause 17(C) shall be
                 binding upon the Noteholders and the Couponholders.

     (b)  Release of existing obligor: Any such agreement by the Trustee
          pursuant to this Clause 17(C) will, if so expressed, operate to

          obligations under this Trust Deed save with respect to its obligations
          relating to the exchange of Notes for Shares. Not later than 14 days
          after the execution of any such documents and after compliance with

          17 as soon as practicable.

     (c)  Completion of substitution: Upon the execution of such documents and
          compliance with such requirements, the Substituted Guarantor will be
          deemed to be named in this Trust Deed as the guarantor of the
          obligations aforesaid of the Company (or of any previous substitute
          under Clause 17(B)) in place of SSC (or of any previous substitute
          under this Clause 17(C) and this Trust Deed will be deemed to be

     Trustee, provided that the retirement or removal of any sole Trustee or
     sole trust corporation will not become effective until a trust corporation
     is appointed as successor Trustee. If a sole Trustee gives notice of

     this Clause 18(B), it will use all reasonable endeavors to procure that
     another trust corporation be appointed as Trustee.

          the Noteholders and/or the Couponholders;

     person so appointed such functions as it think fit. The Trustee may by
     notice in writing to the Company and such person remove any person so

     appoints the Trustee to be its attorney in its name and on its behalf to do
     so.

     the majority of such Trustees will (provided such majority includes a trust
     corporation) be competent to carry out all or any of the Trustee's
     functions.

19   Couponholders

     Couponholders and the Couponholders will be deemed to have notice of the
     contents of any notice given to the Noteholders.

(B)  Noteholders assumed to hold Coupons: Even if it has notice to the contrary,
     whenever the Trustee is required to exercise any of its functions by
     reference to the interests of the Noteholders, the Trustee will assume that
     each Noteholder is the holder of all Coupons relating to each Note of which
     he is the bearer.

     proceedings arising out of or in connection therewith (together referred to
     as "Proceedings") may be brought in such courts. Each of the Company and
     SSC irrevocably waives any objection which it may have now or hereafter to

     of the taking of the poll. The demand for a poll shall not prevent the
     continuation of the meeting for the transaction of any business other than
     the question on which the poll has been demanded.

13.  Any poll demanded at any meeting on the election of a chairman or on any
     question of adjournment shall be taken at the meeting without adjournment.

     instruction proposes to vote and in default the block voting instruction

     notarially certified copy of each such block voting instruction and
     satisfactory proof (if applicable) shall, if required by the Trustee, be
     produced by the proxy at the meeting or adjourned meeting but the Trustee
     shall not thereby be obliged to investigate or be concerned with the
     validity of, or the authority of, the proxy named in any such block voting
     instruction.

18.  Any vote given in accordance with the terms of a block voting instruction
     shall be valid even if the block voting instruction or any of the
     Noteholders' instructions pursuant to which it was executed has been
     previously revoked or amended, provided that no intimation in writing of
     such revocation or amendment shall have been received from the relevant
     Paying, Exchange and Transfer Agent by the Company or the Trustee at its
     registered office or by the chairman of the meeting in each case not less
     than 24 hours before the time fixed for the meeting or adjourned meeting at
     which the block voting instruction is used.

     to be signed by the chairman of the meeting at which such resolutions were

     including particularly (but without prejudice to the generality of the
     foregoing) such regulations and requirements as the Trustee thinks
     reasonable: -

     (a)  so as to satisfy itself that persons who purport to requisition a
          meeting in accordance with paragraph 3 or who purport to make any
          requisition to the Trustee in accordance with this Trust Deed are in
          fact Noteholders; and

     (b)  as to the form of voting certificates or block voting instructions to

24.  (A)  If and whenever the Company shall have issued and have outstanding any
          Notes which are not identical and do not form one single series, then
          those Notes which are in all respects identical shall be deemed to
          constitute a separate series of the Notes and the foregoing provisions
          of this Schedule shall have effect subject to the following
          modifications:-

          (i)  a resolution which in the opinion of the Trustee affects one
               series only of the Notes shall be deemed to have been duly passed
               if passed at a separate meeting of the holders of the Notes of
               that series;

          (ii) a resolution which in the opinion of the Trustee affects more
               than one series of the Notes but does not give rise to a conflict
               of interest between the holders of Notes of any of the series so
               affected shall be deemed to have been duly passed if passed at a
               single meeting of the holders of the Notes of all the series so
               affected;

                                       63

<PAGE>   67


          (iii) a resolution which in the opinion of the Trustee affects more
                than one series of the Notes and gives or may give rise to a
                conflict of interest between the holders of the Notes of any of
                the series so affected shall be deemed to have been duly passed
                only if it shall be duly passed at separate meetings of the
                holders of the Notes of each series so affected; and

          (iv)  to all such meetings as aforesaid all the preceding provisions
                of this Schedule shall mutatis mutandis apply as though
                references therein to Notes and holders were references to the
                Notes of the series or group of series in question and to the
                holders of such Notes respectively.

     (B)  If the Company shall have issued and have outstanding (a) Notes which
          are not denominated in Dollars or (b) more than one series of Notes
          denominated in Dollars but in differing denominations, the following
          provisions shall apply. In the case of any meeting of holders of Notes
          of more than one currency the principal amount of such Notes not
          denominated in Dollars shall (i) for the purposes of paragraph 3 be
          the equivalent in Dollars at the spot rate of a bank nominated by the
          Trustee for the conversion of the relevant currency or currencies into
          Dollars on the seventh dealing day prior to the day on which the
          request in writing is received by the Trustee and (ii) for the
          purposes of paragraphs 6, 7, 11 and 15 (whether in respect of the
          meeting or any adjourned such meeting or any poll resulting therefrom)
          be the equivalent in Dollars at such spot rate on the seventh dealing
          day (as defined above) prior to the day of such meeting or, if
          applicable, the taking of such poll. In such circumstances, and where
          separate series of Notes denominated in sterling but of different
          denominations are to be treated together for the purposes of this
          Schedule, on any poll each person present shall have one vote for each
          US$1.00 in principal amount of the Notes (converted as above) which he
          holds.

25.  Nothing in this Trust Deed shall prevent any of the proxies named in any
     block voting instruction or form of proxy from being a director, managing
     director, officer or representative of, or otherwise connected with, the
     Company, or any of its Subsidiaries.

26.  References in this Schedule to Paying, Exchange and Transfer Agents shall,
     where the context requires, be taken to be references to Agents.

                    Register and Transfer of Registered Notes

1    The Company and SSC shall at all times ensure that the Registrar maintains

     showing the amount of the Registered Notes from time to time Outstanding
     and the dates of issue and all subsequent transfers and changes of
     ownership thereof and the names and addresses of the holders of the
     Registered Notes. The Trustee and the holders of the Registered Notes or
     any of them and any person authorized by it or any of them may at all
     reasonable times during office hours inspect the register and take copies
     of or extracts from it. The register may be closed by the Company for such
     periods at such times (not exceeding in total 30 business days in any one
     year) as it may think fit.

2    Each Registered Note shall have an identifying serial number which shall be
     entered on the register.

3    The Registered Notes are transferable by execution of the form of transfer
     endorsed thereon under the hand of the transferor or, where the transferor
     is a corporation, under its common seal or under the hand of two of its
     officers duly authorized in writing. In each case the signature(s) must be
     guaranteed by a commercial bank with a correspondent bank in New York City,
     Luxembourg or London or by an institution which is a member of The New York
     Stock Exchange or The American Stock Exchange in New York City or the
     Luxembourg Stock Exchange or London Stock Exchange Limited.

4    The Registered Notes to be transferred must be delivered for registration
     to the specified office of the Registrar or any Transfer Agent with the
     form of transfer endorsed thereon duly completed and executed and must be
     accompanied by such documents, evidence and information as may be required
     pursuant to the Conditions and such other evidence as the Company may
     reasonably require to prove the tide of the transferor or his right to
     transfer the Registered Notes and, if the form of transfer is executed by
     some other person on his behalf or in the case of the execution of a form
     of transfer on behalf of a corporation by its officers, the authority of
     that person or those persons to do so.

5    The executors or administrators of a deceased holder of Registered Notes
     (not being one of several joint holders) and in the case of the death of
     one or more of several joint holders the survivor or survivors of such
     joint holders shall be the only person or persons recognized by the Company
     as having any title to such Registered Notes.

6    Any person becoming entitled to Registered Notes in consequence of the
     death or bankruptcy of the holder of such Registered Notes may upon
     producing such evidence that he holds the position in respect of which he
     proposes to act under this paragraph or of his tide as the Company shall
     require be registered himself as the holder of such

                                       65

<PAGE>   69


     Registered Notes or, subject to the preceding paragraphs as to transfer may
     transfer such Registered Notes. The Company shall be at liberty to retain
     any amount payable upon the Registered Notes to which any person is so
     entitled until such person shall be registered as aforesaid or shall duly
     transfer the Registered Notes.

7    Unless otherwise requested by him, the holder of Registered Notes of any
     series shall be entitled to receive only one Registered Note in respect of
     his entire holding of such series.

8    The joint holders of Registered Notes of any series shall be entitled to
     one Registered Note only in respect of their joint holding of such series
     which shall, except where they otherwise direct, be delivered to the joint
     holder whose name appears first in the register of the holders of
     Registered Notes in respect of such joint holding.

9    Where a holder of Registered Notes has transferred part only of his holding
     of any series there shall be delivered to him without charge a Registered
     Note in respect of the balance of such holding.

10   The Company shall make no charge to the Holders for the registration of any
     holding of Registered Notes or any transfer thereof or for the issue
     thereof or for the delivery thereof at the specified office of the
     Registrar or of any Transfer Agent or by post to the address specified by
     the Holder. If any Holder entitled to receive a Registered Note wishes to
     have the same delivered to him otherwise than at the specified office of
     the Registrar or of any Transfer Agent, such delivery shall be made, upon
     his written request to the Registrar or such Transfer Agent, at his risk
     and (except where sent by post to the address specified by the Holder) at
     his expense.

11   The Holder of a Registered Note may (to the fullest extent permitted by
     applicable laws) be treated at all times, by all persons and for all
     purposes as the absolute owner of such Registered Note notwithstanding any
     notice any person may have of the right, title, interest or claim of any
     other person thereto. The Company and the Trustee shall not be bound to see
     to the execution of any trust to which any Registered Note may be subject
     and no notice of any trust shall be entered on the register. The Holder of
     a Registered Note will be recognized by the Company as entitled to his
     Registered Note free from any equity, set-off or counterclaim on the part
     of the Company against the original or any intermediate holder of such
     Registered Note.

                (B) Title to the Bearer Notes and to the Coupons will pass by
         delivery. Title to the Registered Notes will pass by transfer and
         registration as described in these Terms and Conditions and the Agency
         Agreement. The Company, any Paying Agent or Exchange Agent and the
         Trustee may (to the fullest extent permitted by applicable laws) deem
         and treat the holder of any Bearer Notes and the holder of any Coupon
         as the absolute owner thereof for all purposes (whether or not the
         Bearer Note or Coupon shall be overdue and notwithstanding any notice
         of ownership or writing on the Bearer Note or Coupon or any notice of
         previous loss or theft of the Bearer Note or Coupon). In these
         conditions, (in relation to a Note) "Noteholder" and (in relation to a
         Note or Coupon) "Holder" means the bearer of any Bearer Note or Coupon
         (as the case may be) or the person in whose name a Registered Note is
         registered, as the case may be.

         The Bearer Notes will be represented initially by a temporary global
note (the "Global Note"), without interest coupons, which will be deposited with
a common depository (the "Common Depository") and held on behalf of Morgan
Guaranty Trust Company of New York, as operator of the Euroclear System
("Euroclear"), and Clearstream Banking, societe


                                       24

anonyme ("Clearstream") for credit to the accounts designated by the Noteholders
at Euroclear and Clearstream. The Company undertakes to make definitive Bearer
Notes available for exchange for the Global Note, in whole or in part, on or
after May 1, 1996.

         The Registered Notes will be issued in definitive registered form and
delivered as soon as practicable after the Recapitalization Date to the Lead
Managers for the account of the subscribers thereof as specified by the Lead
Managers upon certification that (i) the holders of the relevant Registered
Notes are not U.S. persons and, (ii) the proposed holder of the relevant
Registered Notes (a) is not, nor is it a nominee for Euroclear or Clearstream or
any other person providing a clearance service within Section 96 of the Finance
Act 1986 of the United Kingdom and (b) is not, nor is it a nominee or agent for,
a person whose business is or includes issuing depository receipts within
Section 93 of the Finance Act 1986 of the United Kingdom.

         The Notes and any Coupons will bear the following legend: "Any United
States person who holds this obligation will be subject to limitations under the
U.S. income tax laws, including the limitations provided in Section 165 (j) and
1287 (a) of the United States Internal Revenue Code of 1986, as amended."

         2.     STATUS

                (A) The Notes and any Coupons are direct, unconditional and
         unsecured obligations of the Company and rank and will rank pari passu,
         without any preference among themselves, and such obligations will rank
         senior to all other outstanding unsecured and subordinated obligations
         of the Company, present and future, but, in the event of bankruptcy or
         insolvency of the Company, only to the extent permitted by the
         applicable laws relating to creditors' rights.

                (B) SSC has, in the Trust Deed, unconditionally and irrevocably
         guaranteed the due and punctual payment of the principal of, and
         interest on the Notes as and when the same shall become due and payable
         together with any additional amounts payable pursuant to Condition 10
         and all other moneys payable under the Trust Deed. The obligations of
         SSC under the terms of the Guarantee constitute direct, unconditional
         and unsecured obligations of SSC and such obligations rank and will
         rank senior to all other outstanding unsecured and subordinated
         obligations of SSC present and future (including without limitation,
         the Convertible Subordinated Reset Debentures due July 15, 2008, issued
         by SSC) but, in the event of bankruptcy or insolvency of SSC, only to
         the extent permitted by applicable laws relating to creditors' rights.

                (C) Following recapitalization, the number of Shares issued and
         outstanding will be approximately 50,400,000.


                                       25

                (D) Shares issued to satisfy obligations hereunder shall be
         validly issued, free and clear of any legends, transfer restrictions,
         and stop orders, fully paid, and non- assessable, free and clear of any
         and all liens, claims, and encumbrances, entitled to be resold without
         any restriction imposed under the Securities Act, except for
         limitations imposed on an "affiliate" as such term is defined in Rule
         144(a) of the Securities Act, and that the holders of such Shares shall
         be entitled to all rights and preferences accorded to a holder of
         Shares. As of the date of this First Supplement, the Shares outstanding
         are currently listed on the New York Stock Exchange Inc."

         3.     COVENANTS

                (A) So long as any Note remains Outstanding (as defined in the
         Trust Deed), the Company will not create or permit to subsist any Lien
         (as defined below) or create, assume or guarantee any Indebtedness (as
         defined below).

                (B) The Company will not merge or consolidate with or sell,
         convey or otherwise dispose of all or substantially all of its assets
         to any other corporation, partnership or other legal entity unless
         (i)(A) the Company shall be the surviving corporation, partnership or
         other legal entity in the case of a merger or (B) (I) the surviving,
         resulting or transferee corporation, partnership or other legal entity
         ("the successor corporation") shall expressly assume the due and
         punctual payment of the principal of and interest on all the Notes,
         according to their tenor, and due and punctual performance of all of
         the covenants and obligations of the Company under the Notes and (II)
         if the successor corporation is not organised under the laws of the
         U.S. or any State thereof or the District of Columbia, it shall agree
         to indemnify and hold harmless the holder of each Note or Coupon
         against the then existing or future tax, assessment or governmental
         charge imposed on such holder by a jurisdiction other than the U.S. or
         any political subdivision or taxing authority thereof or therein with
         respect to and withheld on the making of, any payment of principal of
         or interest on such Note which would not have been so imposed and
         withheld had such merger, consolidation, sale or conveyance not been
         made and any tax, assessment or governmental charge imposed on or
         relating to, and any costs and expenses involved in such merger,
         consolidation, sale or conveyance and (ii) the Company or such
         successor corporation, as the case may be, shall not immediately after
         such merger, consolidation, sale or conveyance be in default in the

         Notes.

                (C) Without prejudice to the provisions of Condition 8(F), SSC
         may not merge or consolidate with or sell, convey or otherwise dispose
         of all, or substantially all of its assets to any other corporation,

         corporation, partnership or other legal entity in the case of a merger
         or (B) (I) the successor corporation, partnership or other legal entity
         shall expressly assume the obligations of SSC under the Trust Deed and

<PAGE>   98

         corporation, partnership or other legal entity (together with its
         subsidiaries, if any) on a consolidated basis shall have a Consolidated
         Net Worth (as defined below) following the transaction equal to or
         greater than the Consolidated Net Worth of SSC before the transaction.

                (D) Upon any merger, consolidation, sale or conveyance as
         provided above, the successor or surviving corporation shall succeed to
         and be substituted for and may exercise every right and power of and be
         subject to all of the obligations of the Company under the Notes or SSC
         under the Trust Deed referred to in Condition 2(B), as the case may be,
         with the same effect as if the successor or surviving corporation had
         been named as the Company or SSC therein and herein and the Company or
         SSC, as the case may be, shall be released from its liability as
         obligor under the Notes and/or the Trust Deed.

         4.     REGISTRATION

         The Company will cause to be kept at the specified office of the
Registrar a register (the "Register") on which shall be entered the names and
addresses of the holders of the Registered Notes and the particulars of the
Registered Notes held by them and or all transfers of Registered Notes and
exchanges of Registered Notes. Holders of Registered Notes will be entitled to
receive only one Registered Note in respect of their holding.

         5.     EXCHANGE BETWEEN BEARER AND REGISTERED NOTES

                (A) Exchange of Bearer Notes for Registered Notes. At the option
         of the holder thereof upon presentation, at any time on or after the
         Recapitalization Date, of a duly completed and signed request for
         exchange in the form for the time being currently obtainable from the
         specified office of the Registrar or a Transfer Agent (a "Registration
         Request") together with the relevant Bearer Note, subject to the terms
         of the Agent Agreement and to Conditions 5(E) and 5(F), Bearer Notes
         are exchangeable for the same aggregate principal amount of Registered
         Notes provided that (save as provided below) all unmatured Coupons
         relating thereto are attached thereto or are surrendered therewith.
         Bearer Notes surrendered in exchange for Registered Notes from and
         including the Record Date (as defined below) in respect of any Interest
         Payment Date (as defined below) up to and including such Interest
         Payment Date will not be required to be surrendered with the Coupon
         relating to the interest payable on such Interest Payment Date.
         Interest on a Registered Note issued in exchange will accrue as from
         the immediately preceding Interest Payment Date or, none, on the
         Recapitalization Date, except where issued in respect of a Bearer Note
         surrendered during the period from and including the Record Date in
         respect of an Interest Payment Date up to and including such Interest
         Payment Date, in which event interest shall accrue as from such
         last-mentioned Interest Payment Date. Bearer Notes may only be
         surrendered in exchange for Registered Notes at the specified



                                       27
<PAGE>   99

         office of the Registrar or of a Transfer Agent.

                The Registrar or the relevant Transfer Agent will within three
         Business Days (as defined below) of the presentation of any
         Registration Request together with the relevant Bearer Note deliver a
         Registered Note to the Noteholder at its specified office, or (at the
         risk and, if mailed at the request of the Noteholder otherwise than by
         ordinary mail at the expense of the Noteholder), mail the Registered
         Note by uninsured mail to such address as the Noteholder may request. A
         Noteholder will receive only one Registered Note for all of the Bearer
         Notes which are the subject of a single Registration Request.

                (B) Exchange of Registered Notes for Bearer Notes. At the option
         of the holder thereof, upon presentation at any time on or after the
         Recapitalization Date, of a duly completed and signed request for
         exchange in the form for the time being obtainable from the specified
         office of the Registrar or a Transfer Agent (a "Bearer Request")
         together with the relevant Registered Note, subject to the terms of the
         Agency Agreement and to Conditions 5(E) and 5(F), Registered Notes are
         exchangeable in whole or in part in an Authorised Denomination for the
         same aggregate principal amount of Bearer Notes. Interest on a
         Registered Note surrendered for exchange will cease to accrue as from
         the Interest Payment Date immediately preceding the date of surrender
         or, if none, the Recapitalization Date, except where the date of
         surrender falls during any period from and including the Record Date in
         respect of an Interest Payment Date up to and including such Interest
         Payment Date, in which event interest will cease to accrue as from such
         last-mentioned Interest Payment Date. Registered Notes may only be
         surrendered in exchange for Bearer Notes at the specified office of the
         Registrar or a Transfer Agent.

                The Registrar or the relevant Transfer Agent will within three
         Business Days of the presentation of any Bearer Request together with
         the relevant Registered Note deliver the Bearer Note or Bearer Notes
         requested together with all Coupons in respect of all Interest Payment
         Dates after the date of presentation (other than the Coupon in respect
         of the next Interest Payment Date after the date of presentation in the
         case of a Registered Note presented for exchange during any period from
         and including the Record Date in respect of such Interest Payment Date
         and up to and including such Interest Payment Date) and, in the case of
         exchange of part only of a Registered Note, a Registered Note for the
         balance after such exchange, in each case at the specified office of
         the Registrar or the relevant Transfer Agent, or (at the risk and, if
         mailed at the request of the Noteholder otherwise than by ordinary
         mail, at the expense of the Noteholder) mail the Bearer Note or Bearer
         Notes together with all Coupons as aforesaid and any such Registered
         Note by uninsured mail to such address as the Noteholder may request.

                  (C) Transfer of Registered Notes. Registered Notes, may,
         subject to the terms



                                       28
<PAGE>   100

         of the Agency Agreement and to Conditions 5 (E) and 5 (F) be
         transferred in whole or in part in an Authorised Denomination by
         lodging the relevant Registered Note (with the application for transfer
         in respect thereof duly executed and duly stamped where applicable) at
         the specified office of the Register or a Transfer Agent. No transfer
         of a Registered Note will be valid unless and until entered on the
         Register. A Registered Note may be registered only in the name of, and
         transferred only to, a named person (or persons, not exceeding four in
         number).

                The Registrar or the relevant Transfer Agent will within three
         Business Days of any duly made application for the transfer of a
         Registered Note deliver a Registered Note to the transferee (and, in
         the case of a transfer of part only of a Registered Note, deliver a
         Registered Note for the untransferred balance to the transferor), at
         the specified office of the Register or the relevant Transfer Agent, or
         (at the risk and, if mailed at the request of the transferee or, as the
         case may be, the transferor otherwise than by ordinary mail, at the
         expense of the transferee or, as the case may be, the transferor) mail
         the Registered Note by uninsured mail to such address as the transferee
         or, as the case may be, the transferor may request.

                (D) Formalities Free of Charge. Such exchange or transfer will
         be effected without charge subject to (i) the person making such
         request for exchange or such application for transfer paying or
         procuring the payment of any taxes, duties and other governmental
         charges payable in connection therewith, (ii) the Registrar or the
         relevant Transfer Agent (in the case of exchange of Registered Notes
         for Bearer Notes or the transfer of Registered Notes) being satisfied
         with the documents of title and/or identity of the person making the
         request or application and (iii) such reasonable regulations as the
         Company may from time to time agree with the Registrar. The exchange of
         Bearer Notes for Registered Notes and Registered Notes for Bearer Notes
         will be subject to the provisions of all applicable fiscal or other
         laws and regulations in effect at the time of such exchange.

                (E) Closed Periods. Neither the Company, the Registrar, nor any
         Transfer Agent will be required (i) to register the transfer of any
         Registered Note, (ii) to exchange any Bearer Note for a Registered Note
         or (iii) to exchange any Registered Note (or part thereof) for a Bearer
         Note (a) during the period of seven calendar days immediately prior to
         May 1, 2001, or any earlier date fixed for redemption of the Notes
         pursuant to Condition 9, (b) in respect of which an Exchange Notice (as
         defined below) has been delivered in accordance with Condition 8 or (c)
         in respect of which the Trustee or the Company have exercised Exchange
         Rights under Condition 8(D) or 8(E), as the case may be. A Bearer Note
         or Registered Note called for redemption may, however, be exchanged for
         a Registered Note or Bearer Note, as the case may be, which is
         simultaneously surrendered not later than the relevant Record Date.



                                       29
<PAGE>   101

                (F) Certification of Non-U.S. Person Status. Neither the Company
         nor the Registrar will be required to register the transfer of any
         Registered Note prior to the Recapitalization Date unless the
         transferee provides written certification that such transferee is not a
         U.S. person or unless the transfer of the Registered Notes is exempt
         from the registration under the Securities Act and any applicable state
         securities laws. In addition, the transferee of a Registered Note will
         be required to complete certain documentation to ensure the Company's
         compliance with U.S. federal income tax laws.

         6.     INTEREST AND ADDITIONAL INTEREST

         As of the Recapitalization Date, the Notes bear interest from (and
including) the Recapitalization Date, at the rate of 8 percent per annum,
payable in Shares, semiannually on March 21 and September 21 in each year (each
an "Interest Payment Date"), the first such payment to be made on September 21,
2000, in respect of the period from and including the Recapitalization Date to
(but excluding) September 21, 2000, with value of the Shares to be issued being
equal to 90% of the average of the high and low trading prices for the five (5)
trading days immediately prior to the Interest Payment Date. However, if:

         (i) Shares are not listed on the New York Stock Exchange Inc., and the
         holders of a majority of the principal amount of the Notes Outstanding
         have requested that interest payments be made in cash; or,

         (ii) upon the occurrence of an Event of Default

the interest shall be paid in cash and will amount to U.S. $40.00 per U.S.
$1,000 principal amount of the Notes. The number of Shares to be issued shall be
made available by SSC to the Trustee and/or the Transfer Agent and shall be
rounded down to the nearest whole number. Receipt of the Shares will be made
upon presentation of a Bearer Note to Paying Agent, which Note shall be stamped
to reflect such payment or issuance or in the case of Registered Notes, to the
Holders shown on the Register on the Anniversary Date.

         Each Note will cease to bear interest (i) from its due date for
redemption unless, upon due presentation, payment of the principal in respect of
the Note is improperly withheld or refused or unless default is otherwise made
in respect of such payment, in which event interest shall continue to accrue as
provided in the Trust Deed and (ii) where the Exchange Right (as defined below)
shall have been exercised, or the Trustee or the Company shall have exercised
Exchange Rights pursuant to Conditions 8(D) and 8(E), respectively, from the
Interest Payment Date last preceding the relevant Exchange Date or, if the Notes
are exchanged before the first Interest Payment Date, since the Recapitalization
Date.

         When interest is required to be calculated in respect of a period of
less than a full year, it shall be calculated on the basis of a 360 day year
consisting of 12 months of 30 days each


                                       30
<PAGE>   102

and, in the case of an incomplete month, the number of days elapsed.

         7.     PAYMENTS

                (A) Payments of principal in respect of each Bearer Note and any
         net proceeds payable under Conditions 8(D) and 8(E) will only be made,
         in the case of Bearer Notes, against presentation and surrender (or, in
         the case of part payment only, endorsement) of the relevant Bearer Note
         at the specified office of any of the Paying Agents or in the case of
         Registered Notes, to the persons shown on the Register at the close of
         business seven Business Days prior to the relevant payment date (the
         "Record Date") and subject to surrender of the Registered Notes at the
         specified office of the Registrar or any Transfer Agent. Each such
         payment and any payment of net proceeds pursuant to Conditions 8(D) or
         8(E) will be made at the specified office of any Paying Agent, at the
         Holder's option, by U.S. dollar cheque drawn on, or by transfer to a
         U.S. dollar account maintained by the payee with, a bank in London,
         England and in the case of Registered Notes, by U.S. dollar cheque
         drawn on a bank in London, England and mailed, not later than the due
         date for payment (at the risk and, if mailed at the request of the
         holder otherwise than by ordinary mail, expense of the holder) to the
         holder or to the first named of joint holders of the relevant
         Registered Notes at his registered address outside the United States
         and its possessions or in accordance with mandate instructions
         acceptable to the Registrar, subject in all cases to any applicable
         fiscal or other laws and regulations, but without prejudice to the
         provisions of Condition 12.

                (B) Shares issued on an Interest Payment Date pursuant to
         interest due on the Bearer Notes will be made against presentation and
         surrender (or, if applicable, endorsement) of the relevant Coupons at
         the specified office of any of the Paying Agents or, in the case of
         Registered Notes, to the persons shown on the Register at the close of
         business on the Record Date. Delivery of Shares will be made at the
         specified office of any Paying Agent at the Holder's option. In the
         event that interest is paid in cash, such interest payments will be
         made at the specified office of any Paying Agent, at the Holder's
         option, by U.S. dollar cheque drawn on, or by transfer to a U.S. dollar
         account maintained by the payee with, a bank in London, England and in
         the case of Registered Notes, by U.S. dollar cheque drawn on a bank in
         London, England and mailed, not later than the due date for payment (at
         the risk and, if mailed at the request of the holder otherwise than by
         ordinary mail, expense of the holder) to the holder or to the first
         named of joint holders of the relevant Registered Notes at his
         registered address outside the United States and its possessions or in
         accordance with mandate instructions acceptable to the Registrar,
         subject in all cases to any applicable fiscal or other laws and
         regulations, but without prejudice to the provisions of Condition 12.

                  (C) Each Bearer Note should be presented for redemption
         together with all


                                       31
<PAGE>   103

         unmatured Coupons relating to such Note, failing which the full amount
         of any missing unmatured Coupon (or, in the case of payment not being
         made in full, that proportion of the full amount of the missing
         unmatured Coupons which the amount so paid bears to the total amount
         due) will be deducted from the amount due for payment. Each amount so
         deducted will be paid in the manner mentioned above against
         presentation and surrender (or, in the case of part payment only,
         endorsement) of such missing Coupon at any time before the expiry of 10
         years after the Relevant Date (as defined in Condition 10) in respect
         of the relevant Note (whether or not such Coupon would otherwise have
         become void pursuant to Condition 12), or, if later, five years after
         the date on which such Coupon would have become due, but not
         thereafter.

                A holder shall be entitled to present a Bearer Note or Coupon
         for payment only on a Presentation Date and shall not be entitled to
         any further interest or other payment if a Presentation Date is after
         the due date.

                "Presentation Date" means a day which (subject to Condition 12):

                (a) is or falls after the relevant due date but, if the due date
                is not or was not a Business Day in New York, is or falls after
                the next following such Business Day, and

                (b) is a Business Day in the place of the specified office of
                the Paying Agent at which the Bearer Note or Coupon is presented
                for payment and in the case of payment by transfer to a U.S.
                dollar account in London as referred to above, in London.

                "Business Day" means each Monday, Tuesday, Wednesday, Thursday
         and Friday which is not a day on which banking institutions in the City
         of New York, New York. are authorised or obliged by law, regulation or
         executive order to close and, as the context may require, the day on
         which commercial banks are open for business in the relevant place of
         presentation or payment.

                When making cash payments to Noteholders or Couponholders,
         fractions of one cent will be rounded down to the nearest whole cent.
         When issuing Shares to Noteholders or Couponholders, Shares shall be
         rounded up to the nearest whole number.

                The names of the initial Paying Agents, Exchange Agents and
         Transfer Agents and Registrar and their initial specified offices are
         set out at the end of the "Terms and Conditions of the Notes." The
         Company reserves the right, subject to the prior written approval of
         the Trustee, at any time to vary or terminate the appointment of any
         Paying Agent, Exchange Agent or the Registrar and to appoint additional
         or other


                                       32

         Paying Agents, Exchange Agents or Registrar, provided that it will at
         times maintain (i) at least two Paying Agents, two Exchange Agents and
         two Transfer Agents having specified offices in separate European
         cities approved by the Trustee, one of which, shall be in London and
         (ii) a Registrar with a specified office in New York. Notice of any
         termination or appointment and of any changes in specified offices will
         be given to the Noteholders promptly by the Company in accordance with
         Condition 17.

         8.     EXCHANGE

                (A)   Exchange Period and Price

                      (i) Noteholders shall have the right, upon the approval of
                Noteholders holding a clear majority in principal amount of the
                Notes for the time being Outstanding and subject to Condition
                9(G), any other applicable restrictions provided herein, and
                applicable laws and regulations, to require SSC to exchange all
                or any of their Notes at their principal amount in exchange for
                Shares at any time during the Exchange Period, as defined below.
                The right of a Noteholder to exchange any Note into Shares is
                hereinafter called the "Exchange Right." Upon exchange, the
                right of the exchanging Noteholder to repayment of the principal
                amount of the Note to be exchanged (and, subject as provided in
                Condition 8(B) (iv), accrued interest thereon) shall be
                extinguished and released, and in consideration and in exchange
                therefore, SSC shall allot and issue Shares credited as paid up
                in full as provided in this Condition 8. Subject to and upon
                compliance with the provisions of these Conditions, the Exchange
                Right attaching to any Note maybe be exercised, at the option of
                the holder thereof, during the Exchange Period.

                      "Exchange Period" means, provided SSC shareholders
                approve, on or before June 1, 2000, the authorization and
                issuance of the requisite number of Shares to Noteholders:

                      (i) any time on and after 120 days from the
                Recapitalization Date (or such later date as agreed by the
                affirmative vote of a majority of the principal amount of Notes
                Outstanding), up to the close of business on the second Business
                Day preceding the Maturity Date; or,

                      (ii) if such Note shall have been called for redemption
                pursuant to Condition 9 (B), the date seven calendar days prior
                to the date fixed for redemption thereof.

                      The number of Shares to be issued on exchange of a Note
                will be determined by dividing the principal amount of the Note
                to be exchanged (or, in the case of exchange of part only of the
                principal amount of the relevant


                                       33
<PAGE>   105

                Note, the principal amount thereof being exchanged) by the
                Exchange Price (as defined below) in effect on the Exchange
                Date, with the result being rounded down to the nearest whole
                number.

                      (ii) An Exchange Right may only be exercised in respect of
                an authorised denomination of Notes. If more than one Note is
                exchanged at any one time by the same holder, the number of
                Shares to be issued upon such exchange will be calculated on the
                basis of the aggregate principal amount of the Notes to be
                exchanged. Fractions of Shares will not be issued on exchange
                and no cash adjustments will be made in respect thereof.

                      (iii) The price at which Shares will be issued upon
                exchange (the "Exchange Price") will initially be U.S. $1.50 per
                Share but will be subject to adjustment in the manner provided
                in Condition 8(C).

                      (iv) Notwithstanding the provisions of paragraph (i) of
                this Condition 8(A), if the Company shall default in making
                payment in full in respect of any Note which shall have been
                called for redemption prior to the Maturity Date, the Exchange
                Right attaching to such Note will continue to be exercisable
                (unless already exercised by the Trustee pursuant to Condition
                8(D) or by the Company pursuant to Condition 8(E) up to, and
                including the close of business (at the place where the Note is
                deposited in connection with the exercise of the Exchange
                Right), on the date upon which the full amount of the moneys
                payable in respect on such Note has been duly received by the
                Trustee or the Principal Paying Agent or, if earlier, the
                Maturity Date.

                      "Maturity Date" means May 1, 2001, unless extended
                pursuant to Condition 9(A).

                      (v) As used in the Conditions, the expression "Shares"
                means common stock U.S. $0.01, of SSC or its survivor (and all
                other (if any) shares or stock resulting from any subdivision,
                consolidation or re-classification of such shares).

                      (vi) In the case of a Bearer Note, an Exchange Right may
                only be exercised in respect of the total principal amount of
                such Bearer Note and, in the case of a Registered Note an
                Exchange Right may only be exercised in respect of an Authorised
                Denomination. Where an Exchange Right is exercised in respect of
                part only of a Registered Note, the old Registered Note shall be
                canceled and a new Registered Note for the balance thereof shall
                be issued in lieu thereof without charge but upon payment by the
                Holder of any taxes, duties and other governmental charges
                payable in connection therewith and the Registrar will within
                seven Business Days of the relevant Exchange Date deliver such
                new Registered Note to the Noteholder at the specified office of
                the



                                       34
<PAGE>   106

                Registrar or (at the risk and, if mailed at the request of the
                Noteholder otherwise than by ordinary mail, at the expense of
                the Noteholder) mail the new Registered Note by uninsured mail
                to such address as the Noteholder may request.

                      In the case of a Registered Note, an Exchange Right may
                not be exercised by the Noteholder during the period commencing
                on the Record Date in respect of any payment and ending on the
                due date for such payment (both days inclusive).

                (B)   Procedure for Exchange

                      (i) To exercise the Exchange Right attaching to any Note,
                the holder thereof must complete, execute and deposit at his own
                expense during normal business hours at the specified office of
                the Principal Exchange Agent or any of the other Exchange Agents
                or, in the case of a Registered Note, the Registrar, a notice of
                exchange (an "Exchange Notice") in duplicate in the form (for
                the time being current) obtainable from the specified office of
                each Exchange Agent, together with the relevant Note and any
                amount to be paid by the Noteholder pursuant to this Condition
                8(B)(i).

                      The exchange date in respect of a Note (the "Exchange
                Date") must fall at a time when the Exchange Right attaching to
                that Note is expressed in these Conditions to be exercisable and
                will be deemed to be the Business Day immediately following the
                date of the surrender of the Note and delivery of such Exchange
                Notice and, if applicable, any payment to be made or indemnity
                given under these Conditions in connection with the exercise of
                such Exchange Right or, in the case of an automatic exchange on
                redemption pursuant to Condition 8(D), the relevant redemption
                date. An Exchange Notice once delivered shall be irrevocable.
                "Stock Exchange Business Day" means any day (other than a
                Saturday or Sunday) on which The New York Stock Exchange Inc. or
                the Alternative Stock Exchange (as defined in Condition
                11(A)(v)(a)), as the case may be, is open for business.

                      A Noteholder or the Trustee delivering a Note for exchange
                must pay (in the case of the Trustee, by way of deduction from
                the net proceeds of sale referred to in Condition 8(D)) any
                taxes and capital, stamp, issue and registration duties arising
                on exchange (other than any taxes or capital, or stamp duties
                payable in the U.S. or in the place of the Alternative Stock
                Exchange, as the case may be, by SSC in respect of the allotment
                and issue of Shares and listing of the Shares on exchange) and
                such Noteholder or the Trustee (as the case may be) must pay (in
                the case of the Trustee, by way of deduction from the net
                proceeds of sale as aforesaid) all, if any, taxes arising by
                reference to any



                                       35
<PAGE>   107

                disposal or deemed disposal of a Note in connection with
                such exchange.

                      Until such time as SSC shall have either, to the
                satisfaction of the Trustee, complied with its obligations under
                or made the determination referred to in Condition 11(A)(iii), a
                Noteholder or the Trustee delivering a Note for exchange on
                behalf of a Noteholder must either (i) provide a written
                certification that the Noteholder is not a U.S. person, that the
                Note is not being exchanged on behalf of a U.S. person, and that
                such persons are located outside the U.S., acquired the Notes to
                be exchanged outside the U.S., and are not affiliates of SSC or
                persons acting on behalf of an affiliate of SSC; or (ii) provide
                a written opinion of U.S. legal counsel, in form and substance
                acceptable to SSC, to the effect that the exchange of the Note
                for Shares is exempt from registration under the Securities Act
                and any applicable state securities law.

                      (ii) As soon as practicable, and in any event not later
                than 14 calendar days after the Exchange Date, SSC will in the
                case of Notes exchanged on exercise of the Exchange Right,
                whether by the Noteholder or by the Trustee, or a Note being
                exchanged in accordance with Condition 8(E) and in respect of
                which an Exchange Notice has been delivered and the relevant
                Note and amounts payable by the relevant Noteholder, or, as the
                case may be, the Trustee deposited as permitted by sub-paragraph
                (i) above, cause the person or persons designated for the
                purpose in the Exchange Notice to be registered as Holder(s) of
                the relevant number of Shares and will make a certificate or
                certificates for the relevant Shares available for collection at
                SSC's principal office in Boise, Idaho or, if so requested in
                the relevant Exchange Notice, will deliver such certificate or
                certificates to the person and at the place specified in the
                Exchange Notice together with any other securities, property or
                cash required to be delivered upon exchange and such assignments
                and other documents (if any) as may be required by law to effect
                the transfer thereof.

                      (iii) The person or persons specified for that purpose
                will be deemed for all purposes to be the holder of record of
                the number of Shares issuable upon exchange with effect from the
                Exchange Date. The Shares issued upon exchange of the Notes will
                in all respects rank pari passu with the issued and outstanding
                Shares in issue on the relevant Exchange Date except for any
                right excluded by mandatory provisions of applicable law. A
                Holder of Shares issued on exchange of Notes shall not be
                entitled to any rights the Record Date for which precedes the
                relevant Exchange Date.

                      (iv) If any notice requiring the redemption of any Notes
                is given pursuant to Condition 9(B) on or after the fifteenth
                calendar day prior to the Record Date in respect of any dividend
                payable in respect of the Shares where such notice


                                       36
<PAGE>   108

                specifies a date for redemption falling on or prior to the next
                following Interest Payment Date, interest shall (subject as
                hereinafter provided) accrue on Notes (i) which shall be been
                delivered for exchange on or after such Record Date or (ii) to
                which the election by the Trustee provided for in Condition 8(D)
                applied on or after such Record Date, in each case from the
                preceding Interest Payment Date (or, if the relevant Exchange
                Date falls before the first Interest Payment Date, from the
                Recapitalization Date, to the relevant Exchange Date) provided
                that the relevant Noteholder's entitlement to interest shall on
                any Note, in the event the Shares allotted on exchange thereof
                shall carry an entitlement to receive such dividend, be limited
                to the amount by which the interest he or it would have received
                had no exchange taken place exceeds the amount of the dividend
                received on such Shares. Any such interest shall be paid by the
                Company not later than 14 calendar days after the relevant
                Exchange Date by issuance of Shares in accordance with
                instructions given by the relevant Noteholder or, in the case of
                such election by the Trustee, the Trustee.

                      Save as provided in this sub-paragraph (iv), no payment or
                adjustment will be made on exchange for any interest accrued on
                exchanged Notes since the Interest Payment Date last preceding
                the relevant Exchange Date, or, if the Notes are exchanged
                before the first Interest Payment Date, since the
                Recapitalization Date, including any payment or issuance of
                Shares pursuant to Condition 6(B).

                (C)   Adjustments in Exchange Price

                The Exchange Price will be subject to adjustment in certain
         events set out in the Trust Deed, including:

                      (i) the making of a Stock Split;

                      (ii) the consolidation and reclassification of Shares;

                      (iii) the grant, issue or offer, to the holders of Shares,
                of rights or warrants entitling them to subscribe for or
                purchase Shares or any securities exchangeable for Shares, at a
                consideration per Share less than the Current Market Price per
                Share;

                      (iv) the distribution, to the holders of Shares, of shares
                of capital stock of SSC, evidence of indebtedness of SSC, assets
                (other than annual or interim dividends in cash) or rights or
                warrants to subscribe for or purchase securities (other than
                those rights and warrants mentioned in (iii) above);

                      (v) the issue of securities (other than the Notes or in
                any of the


                                       37
<PAGE>   109

                circumstances mentioned in (iii) above) exchangeable for Shares
                or of rights or warrants to subscribe for or purchase Shares or
                securities exchangeable for Shares (other than those rights and
                warrants mentioned in (iii) above), at a consideration per Share
                less than the Current Market Price per Share; and

                      (vi) the issue of Shares (other than Shares issued on
                conversion or exchange of any exchangeable securities issued by
                SSC (including the Notes) or on the exercise of any rights or
                warrants granted issued or offered by SSC or in any of the
                circumstances described in (i) and (ii) above or Shares issued
                to stockholders of any company which merges into or consolidates
                with SSC, in proportion to their shareholding in such company
                immediately prior to such merger, upon such merger) at a
                consideration per Share less than the Current Market Price per
                Share; provided, however, that the Exchange Price will not be
                reduced as a result of any such adjustment, and the Company
                covenants in the Trust Deed not to take any action, if, after
                giving effect thereto, the Exchange Price would be reduced to
                such an extent that, under applicable law then in effect Notes
                may not be exchanged at such reduced Exchange Price for legally
                issued, fully paid and assessable Shares. No adjustment will be
                made where such adjustment would be less than 5 percent of the
                Exchange Price then in effect. Any adjustment not so made will
                be carried forward and taken into account in any subsequent
                adjustment. On any adjustment, the resultant Exchange Price, if
                not an integral multiple of one cent shall be rounded down to
                the nearest we cent. Any adjustment will be notified by the
                Trustee to the Noteholders in accordance with Condition 17.

                      "Stock Split" means any kind of stock split in relation to
                the Shares and includes a free share distribution, a stock
                dividend and a sub-division.

                      "Current Market Price" means in respect of a Share on a
                particular Stock Exchange Business Day the average of the high
                and low sale prices (or, if no sales prices are reported, the
                average of the high and low bid prices) as reported in the New
                York Stock Exchange Inc.'s Composite Transactions (or the
                equivalent quotations of an Alternative Stock Exchange, as the
                case may be).

                      The Exchange Price may not be reduced so that, on exchange
                of Notes, Shares would be issued at a discount to their par
                value.

                      Where more than one event which gives or may give rise to
                an adjustment to the Exchange Price occurs within such a short
                period of time that in the opinion of the Company's auditors
                (the "Auditors") the foregoing provisions would need to be
                operated subject to some modification in order to give the
                intended result, such modification shall be made to the
                operation of the foregoing provisions as may be advised by the
                Auditors to be in their opinion



                                       38

                appropriate in order to give such intended result.

                      No adjustment will be made to the Exchange Price when
                Shares or other securities (including rights or options) are
                issued, offered or granted to employees; (including directors
                holding executive office) of SSC or any Subsidiary or any
                associated company of SSC pursuant to any Employee Share Scheme
                (as defined in the Trust Deed).

                (D)   Exchange on Redemption

                The Trust Deed provides that the Trustee may, at its absolute
         discretion (and without any responsibility for any loss occasioned
         thereby), within the period commencing on the date six Business Days
         prior to, and ending at the close of business in New York City prior
         to, the date fixed for redemption of any of the Notes (including any
         redemption under Conditions 9(A), 9(B) and 9(C)), elect by notice in
         writing to the Company and SSC to exchange as of such redemption date
         the aggregate number of Notes due for redemption on such date and in
         respect of which Exchange Rights have not been exercised by Noteholders
         ("Unexercised Notes") into Shares at the Exchange Price applicable at
         such redemption date if all necessary consents (if any) have been
         obtained and the Trustee is satisfied or is advised by a reputable
         independent merchant bank appointed by it that the net proceeds of an
         immediate sale of the Shares arising from such exchange (disregarding
         any liability other than a liability of the Trustee) to taxation or the
         payment of any capital, stamp, issue or registration duties consequent
         thereon) would likely to exceed by 5 percent or more the amount of
         redemption moneys and interest Shares which would otherwise be payable
         in respect of interest accrued since the Interest Payment Date
         immediately preceding such redemption date or, if such date falls
         before the first Interest Payment Date, since the Recapitalization Date
         in respect of such Unexercised Notes.

                Subject to applicable law, the Trustee shall arrange for the
         sale on behalf of the holders of the Unexercised Notes of the Shares
         issued on such exchange as soon as practicable, and (subject to any
         necessary consents being obtained and to the deduction by the Trustee
         of any amount which it determines to be payable in respect of its
         liability to taxation or the payment of any capital, stamp, issue or
         registration duties (if any) and any costs incurred by the Trustee in
         connection with that allotment and sale thereof) the net proceeds of
         sale together with accrued interest payable under Condition 8(B)(iv) in
         respect of such Unexercised Notes (if any) shall be held by the Trustee
         and distributed by the Principal Paying Agent rateably to the holders
         of such Unexercised Notes against due presentation in accordance with
         Condition 7. The amount of such net proceeds of sale shall be treated
         for all purposes as the full amount due by the Company in respect of
         such Unexercised Notes.

                (E)   Mandatory Exchange


                                       39
<PAGE>   111


                      (i) Each Noteholder acknowledges and agrees that the
                Company may, at its own cost (save those expenses or taxes
                referred to in Condition 8 (E) (iii)), at any time on or after
                March 21, 1997, elect to exercise Exchange Right on behalf of
                each and every Noteholder in respect of Notes in whole or in
                part outstanding at the date of such election (the "Mandatory
                Exchange Date"), provided that the Current Market Price of the
                Shares for each of the 30 consecutive Stock Exchange Business
                Days, the last of which, falls on a day not more than 30
                calendar days prior to the date on which notice is given to
                Noteholders of the mandatory exchange under this Condition 8 (E)
                (the "Mandatory Exchange Measuring Period"), is equal to or
                greater than 150 percent of the Exchange Price at the time such
                notice is given. The foregoing right of the Company to exercise
                the Exchange Right (the "Mandatory Exchange Right"), is subject
                to compliance with the provisions of paragraph (iv) below.

                      (ii) Not less than 30 and not more than 60 calendar days
                prior to such Mandatory Exchange Date, the Company shall cause
                written notice of the Mandatory Exchange Date to be given to the
                Trustee, the Paying Agents, the Exchange Agents and the holders
                of the Notes (in accordance with Condition 17 (such notice to
                include a statement of the consequences of failure on the part
                of the Noteholders to perform the obligations specified in this
                Condition (E)). Following such notice each of the Noteholders
                will be required on or before the Mandatory Exchange Date to
                deliver or procure delivery of its Notes together with a duly
                completed Exchange Notice to the specified office of any
                Exchange Agent, during its usual business hours for such
                purposes and perform together with the Company and SSC, the
                obligations applicable to it on exchange specified in this
                Condition 8.

                      (iii) If any Noteholder with respect to whose Notes
                mandatory exchange (pursuant to this Condition 8) is to take
                place shall fail to perform its obligations specified in this
                Condition 8 or shall have a registered address in any territory
                where, in the absence of any registration statement or other
                special formalities or legal requirements, the issue, allotment
                transfer or delivery of the Shares arising on mandatory exchange
                in the reasonable opinion of the Trustee, is or could be
                unlawful or impracticable, subject to applicable law, the
                Trustee shall make arrangements for the sale of such Shares to a
                third party at the best consideration reasonably obtainable by
                the Trustee and arrange for the Principal Paying Agent to pay to
                such Noteholder the consideration received by the Trustee in
                respect of such Shares (after any deduction required to
                reimburse any reasonable and proper expenses incurred in
                arranging any such sale or any taxes payable in connection
                therewith arising solely as a result of the Noteholder's failure
                to perform its obligations under this Condition 8(E)).

<PAGE>   112

                      (iv) Notwithstanding anything herein to the contrary, the
                Company may not exercise the Mandatory Exchange Right unless at
                all times during: (i) the Mandatory Exchange Measuring Period
                and (ii) the period from the end of the Mandatory Exchange
                Measuring Period until and including the Mandatory Exchange
                Date, the Noteholders shall have had the ability to exercise
                their Exchange Rights in full.

                (F)   Consolidation, Amalgamation or Merger

                Without limiting the provisions of Condition 3(C) hereof, in the
         case of any consolidation, amalgamation or merger of SSC with any other
         corporation (other than a consolidation, amalgamation or merger in
         which SSC is the continuing corporation), or in the case of any sale or
         transfer of all or substantially all, of the assets of SSC, SSC will
         forthwith notify the Noteholders of such event in accordance with
         Condition 17 and (so far as legally possible) cause the corporation
         resulting from such consolidation, amalgamation or merger or the
         corporation which shall have acquired such assets, as the case may be,
         to execute a trust deed supplemental to the Trust Deed to ensure that
         the holder of each Note then outstanding will have the right (during
         the period in which such Note shall be exchangeable) to exchange such
         Note into the class and amount of shares and other securities and
         property receivable upon such consolidation, amalgamation, merger, sale
         or transfer by a holder of the number of Shares which would have become
         liable to be issued upon exchange of such Note immediately prior to
         such consolidation, amalgamation, merger, sale or transfer. Such
         supplemental trust deed will provide for adjustments which will be as
         nearly equivalent as may be practicable to the adjustments provided for
         in the foregoing provisions of this Condition. The above provisions of
         this Condition (F) will apply in the same way to any subsequent
         consolidations, amalgamations, mergers, sales or transfers.

                (G)   Limitation on Holder's Right to Exchange

                      (i) Notwithstanding anything to the contrary contained
                herein, no Note may be exchanged to the extent that, after
                giving effect to Shares to be issued pursuant to an Exchange
                Notice, the total number of Shares deemed beneficially owned by
                such Holder (other than by virtue of the ownership of Notes or
                ownership of other securities that have limitation on a Holder's
                right to exchange or exercise, similar to those limitations set
                forth herein), together with all Shares deemed beneficially
                owned by the Holder's affiliates, (as defined in Rule 144 of the
                Act) that would be aggregated for purposes of determining
                whether there exists a group under Section 13 (d) of the
                Securities Exchange Act of 1934, as amended, would exceed 9.9%
                of the issued and outstanding Shares of SSC (the "Restricted
                Ownership Percentage"); provided that, (w) each Holder shall
                have the right at any time and from time to time to reduce its



                                       41
<PAGE>   113

                Restricted Ownership Percentage immediately upon notice to the
                Company, (x) each Holder shall have the right at any time and
                from time to time, to increase its Restricted Ownership
                Percentage and otherwise waive in whole or in part the
                restrictions of this Condition 8(G)(i) upon 61 days' prior
                notice to the Company or immediately in the event of the
                announcement of a pending or proposed Change in Control
                Transaction, (y) each holder can make subsequent adjustments
                pursuant to (w) or (x) any number of times and from time to time
                (which adjustment shall be effective immediately if it results
                in a decrease in the percentage or shall be effective upon 61
                days' prior written notice or immediately in the event of the
                announcement of a pending or proposed Change in Control
                Transaction if it results in an increase in the percentage) and
                (z) each Holder may eliminate or reinstate this limitation at
                any time and from time to time (which elimination will be
                effective upon 61 days' prior notice and which reinstatement
                will be effective immediately). Without limiting the foregoing,
                in the event of the announcement of a pending or proposed Change
                in Control Transaction, any Holder may reinstate immediately (in
                whole or in part) the requirement that any increase in its
                Restricted Ownership Percentage be subject to 61 days' prior
                written notice, notwithstanding such Change in Control
                Transaction, without imposing such requirement on, or otherwise
                changing such Holder's rights with respect to, any other Change
                in Control Transaction. For this purpose, any material
                modification of the terms of a Change in Control Transaction
                will be deemed to result in a new Change in Control Transaction.
                The term "deemed beneficially owned" as used in this Trust Deed
                shall exclude shares that might otherwise be deemed beneficially
                owned by reason of the exchangeability of the Trust Deed. The
                Company shall provide all Holders with the earlier of (i) 20
                days' prior written notice of any such Change in Control
                Transaction, to the extent the Company has prior knowledge of a
                Change in Control Transaction; or (ii) notice on the day
                immediately following the Company's learning of any such
                transaction, but only after, in the case of (i) and (ii), such
                Change in Control Transaction has been publicly disclosed.

                      (ii) Each time (a "Covenant Time") the Holder makes a
                Triggering Acquisition (as defined below) of Shares (the
                "Triggering Shares"), the Holder will be deemed to covenant that
                it will not, during the balance of the day on which such
                Triggering Acquisition occurs, and during the 61-day period
                beginning immediately after that day, acquire additional Shares
                pursuant to its rights to acquire existing at that Covenant
                Time, if the aggregate amount of such additional Shares so
                acquired (without reducing that amount by any dispositions)
                would exceed 9.9% of the number of Shares outstanding at that
                Covenant Time (including the Triggering Shares) minus the number
                of Shares actually owned by the Holder at that Covenant Time
                (regardless of how or when acquired, and including the
                Triggering Shares). A "Triggering Acquisition" means the giving
                of an Exchange Notice or any other acquisition of Shares by the
                Holder or an aggregation party; provided, however, that with



                                       42
<PAGE>   114

                respect to the giving of such Exchange Notice, if the associated
                issuance of Shares does not occur, such event shall cease to be
                a Triggering Acquisition and the related covenant under this
                paragraph shall terminate. At each Covenant Time, the Holder
                shall be deemed to waive any right it would otherwise have to
                acquire Shares to the extent that such acquisition would violate
                any covenant given by the Holder under this paragraph. For the
                avoidance of doubt:

                             (i) The covenant to be given pursuant to this
                             Condition 8(G)(ii) will be given at every Covenant
                             Time and shall be calculated based on the
                             circumstances then in effect. The making of a
                             covenant at one Covenant Time shall not terminate
                             or modify any prior covenants.

                             (ii) The Holder may therefore from time to time be
                             subject to multiple such covenants, each one having
                             been made at a different Covenant Time, and some
                             possibly being more restrictive than others. The
                             Holder must comply with all such covenants then in
                             effect.

         9.     REDEMPTION AND PURCHASE

                      (A) Unless previously redeemed, exchanged, or purchased
                and canceled as provided herein, the Company will redeem the
                Notes at their principal amount on the May 1, 2001.

                Notwithstanding the foregoing, the Company has the option to
         postpone the maturity of the Notes to May 1, 2002, if, the Company
         delivers to Noteholders, on April 1, 2001, Shares equal to 25% of the
         principal amount of the Notes then Outstanding, (assuming that the
         Shares are valued at 90% of the average of the daily high and low for
         the ten trading days prior to April 1, 2001). The Company shall notify
         Noteholders of its intent to postpone the Maturity Date, at least 20
         Trading Days prior to the issuance of the such Shares. As used herein,
         "Trading Days" means any day in which the New York Stock Exchange Inc.
         is open for business. This option may be exercised by the Company only
         if (i) the Shares remain listed on the New York Stock Exchange Inc.;
         (ii) appropriate stockholder approval is obtained; and, (iii) SSC's
         market capitalization exceeds U.S. $50,000,000. At the request of any
         Noteholder, the Company shall provide an officer's certificate signed
         by any two officers of the Company, certifying the following:

                             (i) The Shares have been duly authorized and are
                      fully paid and non-assessable and are being issued free
                      and clear of any liens and encumbrances;

                      our knowledge, conflict with, or constitute a default (or
                      an event which with notice or lapse of time or both would

                officers of the Company on behalf of the Company stating that
                such amendment or change has occurred (irrespective of whether
                such amendment or change is then effective), describing the
                facts leading thereto and stating that such obligation cannot be
                avoided by the Company taking reasonable measures available to
                it and (ii) an opinion in a form satisfactory to the Trustee of
                independent legal advisers of recognised standing to whom the
                Trustee shall have no reasonable objection to the effect that
                such amendment or change has occurred (irrespective of whether
                such amendment or change is then effective)), the Company may at
                its option, having given not less than 30 nor more than 60
                calendar days' notice to the Noteholders in accordance with
                Condition 17 (which notice shall be irrevocable), redeem all the
                Notes but not some only, at their principal amount together with
                interest (if any) accrued to (but excluding) the date of
                redemption, provided that no notice of redemption shall be given
                earlier than 90 calendar days before the earliest date on which
                the Company would be required to pay such additional amounts
                were a payment in respect of the Notes then due.

                      Upon expiry of any such notice period as is referred to in
                this Condition 9(B) (and subject as provided above), the Company
                shall be bound to redeem the Notes at their principal amount
                together with interest accrued to but excluding the redemption
                date.

                (C)   Redemption at the Option of Noteholders

                      Any Noteholder may on or after a Cessation of Listing, by
                completing, signing and depositing at the specified office of
                any of the Paying Agents during normal business hours of such
                Agent at any time after notice of a Cessation of Listing has
                been given by the Company, a notice of redemption in the form
                (for the time being current) obtainable from any of the Paying
                Agents specifying a date for redemption together with the Bearer
                Note or the Registered Note, as the case may be, to be redeemed,
                require the Company to redeem in U.S. dollars all or some only
                of the Notes held by it at their principal amount, plus accrued
                interest to the date of redemption.

                      Any such notice of redemption will be irrevocable unless
                its revocation is approved in writing by the Company not later
                than five days prior to the relevant date for redemption of the
                relevant Note and will bind the Company to redeem the Note to
                which such notice relates. Certificates for Registered Notes and
                Bearer Notes will not be returned to Noteholders except in the
                limited circumstances set out in the Agency Agreement. The
                Company shall notify Noteholders of a Cessation of Listing no
                later than five Business Days after its occurrence in accordance
                with Condition 17. For the purposes of this Condition 9(C)
                "Cessation of Listing" means the consolidation with or merger



                                       45

                into any Person by SSC or the sale, lease, conveyance, transfer
                or other disposal by SSC of its property or assets as an
                entirety or substantially as an entirety to a Person and as a
                result of such transaction the Shares are no longer listed on
                the New York Stock Exchange Inc. or an Alternative Stock
                Exchange.

                      (D) Subject to applicable law, the Company, SSC or any of
                their Subsidiaries or Affiliates (as defined in the Trust Deed)
                may at any time purchase Notes together, in the case of Bearer
                Notes, with unmatured Coupons in any manner and at any price in
                the open market or by private treaty. If purchases are made by
                tender, tenders must be available to all Noteholders alike.
                Notes purchased by the Company, SSC or any of their Subsidiaries
                will forthwith be surrendered for cancellation and shall no
                longer be deemed Outstanding.

                      (E) All Notes which are redeemed by the Company will
                forthwith be canceled (together with all relative unmatured
                Coupons attached to or surrendered with the Bearer Notes), and
                may not be reissued or resold.

         10.      TAXATION.

         All payments or Shares issued in respect of the Notes by the Company
or, as the case may be, SSC shall be made without withholding or deduction for,
or on account of, any present or future taxes, duties, assessments or
governmental charges of whatever nature ("Taxes") imposed or levied by or on
behalf of the U.S. or any political sub-division of, or any authority in, or of,
the U.S. having power to tax, unless the withholding or deduction of the Taxes
is required by law. In that event, the Company or, as the case may be, SSC will
pay such additional amounts as may be necessary in order that the net amounts
received by the Noteholders and Couponholders after the withholding or deduction
shall equal the respective amounts which would have been receivable in respect
of the Notes or, as the case may be, Coupons in the absence of the withholding
or deduction; except that no additional amounts shall be payable in relation to
any payment in respect of any Note or Coupon:

                  (A) to, or to a third party on behalf of, a holder who is
         liable for the Taxes in respect of the Note or Coupon by reason of his
         having some connection with the U.S. other than the mere holding of the
         Note or Coupon; and

                  (B) presented for payment more than 30 calendar days after the
         Relevant Date except to the extent that a holder would have been
         entitled to additional amounts on presenting the same for payment on
         the last day of such period of 30 calendar days; or

                  (C) to, or to a third party on behalf of, a holder who would
         not be liable or subject to the withholding or deduction by making a
         declaration of non-residence


                                       46
<PAGE>   118

         or other similar claim for exemption to the relevant tax authority.

                  As used herein, "Relevant Date" means the date on which the
         payment first becomes due but, if the full amount of the money payable
         has not been received in New York by the Principal Paying Agent or the
         Trustee on or before the due date, it means the date on which, the full
         amount of the money having been so received, notice to that effect
         shall have been duly given to the Noteholders by the Company in
         accordance with Condition 17.

                  Any reference in these Terms and Conditions to any amounts in
         respect of the Notes shall be deemed also to refer to any additional
         amounts which may be payable under this Condition or under any
         undertakings given in addition to, or in substitution for, this
         Condition pursuant to the Trust Deed.

         11.      ADDITIONAL COVENANTS

                  (A)      Undertakings by SSC

                  Whilst any Exchange Right remains exercisable, SSC will, save
         with the approval of an Extraordinary Resolution (as defined in the
         Trust Deed) or with the approval of the Trustee where, in its opinion,
         it is not materially prejudicial to the interests of the Noteholders to
         give such approval:

                         (i) at all times, provided SSC shareholder approval is
                  obtained on or before June 1, 2000, keep available for
                  issuance free from any pre-emptive rights out of its
                  authorised but unissued capital such number of Shares as would
                  enable the Exchange Rights interest payments and all other
                  rights of subscription and exchange for and exchange into
                  Shares to be satisfied in full;

                         (ii) will not create or permit to subsist any Lien
                  relating to or over the shares of the Company, held or
                  beneficially owned by SSC;

                         (iii) to the extent SSC and its counsel determine it is
                  required because an exemption from registration is not
                  available, file with the Securities and Exchange Commission on
                  or before June 30, 1996, and keep effective a Registration
                  Statement on such form as SSC determines to be appropriate in
                  respect of the registration of the Shares to be issued
                  pursuant to the Exchange Rights to U.S. persons and any
                  subsequent resale of such Shares to U.S. persons;

                         (iv) (a) to maintain a listing for all the issued
                         Shares on the New York Stock Exchange Inc., it being
                         understood that if SSC is unable to obtain or maintain
                         such listing of Shares to obtain and maintain a listing



                                       47
<PAGE>   119
                         for all the Shares issued on the exercise of the
                         Exchange Rights on any other stock exchanges or
                         authorised for quotation on NASDAQ or by the National
                         Quotation Bureau Incorporated (each an "Alternative
                         Stock Exchange") as SSC may from time to time (with the
                         written consent of the Trustee) determine and will
                         forthwith give notice to the Noteholders in accordance
                         with Condition 17 of the listing, de-listing or
                         quotation or lack of quotation of the Shares as a
                         class) by any such Alternative Stock Exchange.

                         (v) not in any way modify the rights attaching to the
                  Shares with respect to voting, dividends or liquidation nor
                  issue any class of equity share capital carrying any rights
                  which are more favorable than such rights;

                         (vi) by June 1, 2000, obtain SSC shareholder approval
                  and authorization to effect the following:

                               (a) increase the number of authorized Shares to
                         250,000,000 and,

                               (b) change the Exchange Price to $1.50 per Share,
                         subject to adjustment in the manner provided in
                         Condition 8(C), to New York Stock Exchange Inc.
                         requirements for shareholder approval.

                         (vii) SSC's 10% Senior Convertible Notes due November
                  24, 2002, will not be amended and will remain a debt
                  obligation payable through the issuance of Shares.

                  (B)    Undertakings by the Company

                  Whilst any Exchange Right remains exercisable, the Company
         will, save with the approval of an Extraordinary Resolution or with the
         approval of the Trustee where, in its opinion, it is not materially
         prejudicial to the interests of the Noteholders to give such approval:

                         (i) not incur any Indebtedness other than the Notes;
                  and,

                         (ii) not create or permit to subsist any Lien or other
                  encumbrance or security interest over or otherwise dispose,
                  sell or transfer its interest in the Sunshine Mine.

                  (C) For the purposes of this condition, "Sunshine Mine" means
         that certain real property location in Shoshone County, Idaho, known as
         the "Sunshine Mine", consisting of the ownership rights of the Company

         claims and interests therein owned by the Company.

         12.      PRESCRIPTION

         Bearer Notes and Coupons will become void unless presented for payment
within periods of 10 years (in the case of principal) and five years (in the
case of interest) from the Relevant Date in respect of the Notes or, as the case
may be, the Coupons, subject to the provisions of Condition 7.

         Claims for the payment of principal and issuance of Shares based on
accrued interest and other sums payable in respect to Registered Notes shall be
prescribed unless made within 10 years (in the case of principal) and 5 years
(in the case of interest) from the Relevant Date.

         13.      EVENTS OF DEFAULT

         The Trustee at its discretion may, and if so requested in writing by
the Holders of at least one-quarter in principal amount of the Notes then
Outstanding, or if so directed by an Extraordinary Resolution of the Noteholders
shall, give notice to the Company that the Notes are and they shall accordingly
thereby forthwith become, immediately due and repayable at their principal
amount together with accrued interest (as provided in the Trust Deed) if any of
the following events (each an "Event of Default") shall have occurred (unless
(i) such events are expressly permitted or contemplated by the Trust Deed or
(ii) such Event of Default has been remedied to the satisfaction of the
Trustee):

                  (A) if default is made for a period of 5 Business Days or more
         in the payment of any principal or interest due in respect of the Notes
         or any of them; or

                  (B) if the Company or SSC fails to perform or observe any of
         its other obligations, covenants, conditions or provisions under the
         Notes or the Trust Deed and (except where the Trustee shall have
         certified to the Company in writing that it considers such failure to
         be incapable of remedy in which case no such notice or continuation as
         is hereinafter mentioned will be required) such failure continues for
         the period of 30 calendar days (or such longer period as the Trustee
         may in its absolute discretion permit) next following the service by
         the Trustee on the Company or SSC, as the case may be, of notice
         requiring the same to be remedied; or

                  (C) if (i) any other Indebtedness of the Company, SSC or any
         Principal Subsidiary (as defined below) becomes due and repayable prior
         to its stated maturity by reason of an event of default (howsoever
         described) or (ii) any such Indebtedness is not paid when due or, as
         the case may be, within any applicable grace period (as originally
         provided) or (iii) the Company, SSC or any Principal Subsidiary fails
         to pay



                                       49
<PAGE>   121

         when due (or, as the case may be within any originally applicable grace
         period) any amount payable by it under any present or future guarantee
         for, or indemnity in respect of, any Indebtedness of any Person or (iv)
         any security given by the Company, SSC or any Principal Subsidiary for
         any Indebtedness of any Person or any guarantee or indemnity of
         Indebtedness of any Person or any guarantee or indemnity of
         Indebtedness of any Person becomes enforceable by reason of default in
         relation thereto and steps are taken to enforce such security save in
         any such case where there is a bona fide dispute as to whether the
         relevant Indebtedness or any such guarantee or indemnity as aforesaid
         shall be due and payable, provided that in each such case the
         Indebtedness exceeds in the aggregate US $1,000,000 and in each such
         case such event continues unremedied for a period of 30 calendar days

         obligations, not to exceed US $1,000,000 in any period of 12 months.

                  transferee Subsidiary shall cease to be a Principal Subsidiary
                  under the provisions of this sub-paragraph (B) (but without

London, in the case of Bearer Notes or Coupons, or the Registrar, in the case of
Registered Notes, upon payment by the claimant of the expenses incurred in
connection with the replacement and on such terms as to evidence indemnity and
security as the Company may reasonably require. Mutilated or defaced Notes or
Coupons must be surrendered before replacements will be issued.

         17.      NOTICES

         (or except suspension or curtailment) of postal services within the
         U.S. or elsewhere the Company is unable effectively to give notice to
         holders of Registered Notes through the post, notices to holders of

         Financial Times. Any notice shall be deemed to have been given on the
         date of publication or, if so published more than once, on the date of
         the first publication. If publication as provided above is not
         practicable, notice will be given in such other manner, and shall be
         deemed to have been given on such date, as the Trustee may approve.

                  (C) Couponholders will be deemed for all purposes to have
         notice of the contents of any notice given to the Noteholders in
         accordance with this Condition.

         18.      NOTEHOLDER APPROVALS, MODIFICATION, WAIVER AND AUTHORISATION

         Notes for the time being Outstanding, or by convening a meeting of the
         Noteholders with one or more persons present holding or representing a
         clear majority of the Notes for the time being Outstanding, or at any
         adjourned such meeting, one or more person present, whatever the
         principal amount of the Notes held or represented by him or them. Any
         item once passed pursuant hereto, will be binding on all Noteholders

         Noteholders or



                                       55
<PAGE>   127

         Couponholders, to any modification (subject to certain exceptions) of,
         or to the waiver or authorisation of any breach or proposed breach of,
         any of these Conditions or any of the provisions of the Trust Deed
         which is not, in the opinion of the Trustee, materially prejudicial to
         the interests of the Noteholders or to any modification which is of a
         formal, minor or technical nature or to correct a manifest error.

                  (C) In connection with the exercise by it of any of its
         trusts, powers, authorities or discretions (including, without
         limitation, any modification, waiver, authorisation or substitution),
         the Trustee shall have regard to the interests of the Noteholders as a
         class and, in particular but without limitation, shall not have regard
         to the consequences of the exercise of its trusts, powers, authorities
         or discretions for individual Noteholders and Couponholders resulting
         from their being for any purpose domiciled or resident in, or otherwise
         connected with, or subject to the jurisdiction of, any particular
         territory and the Trustee shall not be entitled to require, nor shall
         any Noteholder or Couponholders be entitled to claim, from the Company,
         the Trustee or any other person any indemnification or payment in
         respect of any tax consequences of any such exercise upon individual
         Noteholders or Couponholders except to the extent already provided for
         in Condition 10 and/or any undertaking given in addition to, or in
         substitution for, Condition 10 pursuant to the Trust Deed.

                  (D) Any modification, waiver or authorisation shall be binding
         on the Noteholders and the Couponholders and, unless the Trustee agrees
         otherwise, any modification shall be notified by the Company to the
         Noteholders as soon as practicable thereafter in accordance with
         Condition 17.

         19.      INDEMNIFICATION OF THE TRUSTEE

         The Trust Deed contains provisions for the indemnification of the
Trustee and for its relief from responsibility, including provisions relieving
it from taking action unless indemnified to its satisfaction.

         The Trust Deed, the Agency Agreement, the Notes and the Coupons are
