               (the "WARRANTS") to acquire an aggregate of 148,459.52 shares of
               SAI Common Stock. The Warrants expire on June 30, 1998. For each
               share of Common Stock to be purchased, the holder is required to
               deliver 70 Warrants together with an exercise price per share of
               Common Stock of $175.00.

               The holders of the Series A Preferred Stock have the right to
               convert each share of the Series A Preferred Stock into 100,000
               shares of Common Stock.

          3.   SERIES B PREFERRED STOCK

                      (c)  (in the event of a transfer by any of the Funds only)
                           if the proposed transfer is to a transferee outside

                           specify that the transferee shall not have assigned

                           authorised representatives) or, where either the
                           transferor or

                           (if any) and under the hand of one of its officers
                           duly authorised in writing or otherwise executed by a
                           duly authorised officer thereof. In this Condition
                           "transferor" shall, where the context permits or
                           requires, include joint transferors or can be

                      (b)  the Certificate of the Debenture must be delivered
                           for registration to the Company accompanied by (i) a

                           person or those persons to do so; (iii) such other
                           evidence as the Company may reasonably require if the
                           form of transfer is executed by some other person on
                           behalf of the Debentureholder; and (iv) such other
                           evidence as the Company may reasonably require to
                           support that the conditions and requirements of this
                           Condition are satisfied.

               (iv)   For so long as neither the Debentures nor the Conversion
                      Shares have been registered under The Securities Act of

                      under the Securities Act of 1933, or an exemption from the

                      legend to that effect.

               Certificate and issue a new certificate under the seal of the
               Company, in favour of the transferee or assignee as applicable.
               Where only part of a principal amount (being that of one or more
               Debentures) of the Debentures in respect of which a Certificate
               is issued is to be transferred, converted or redeemed, a new
               Certificate in respect of the Debenture not so transferred,
               converted or redeemed will, within three (3) Business Days of
               delivery of the original Certificate to the Company be available
               for collection by the Debentureholders.

                                      40

 
          (C)  FORMALITIES FREE OF CHARGE

               Registration of transfer of Debentures will be effected without
               charge by or on behalf of the Company, but upon payment (or the
               giving of such indemnity as the Company may require) in respect
               of any tax or other governmental charges which may be imposed in
               relation to such transfer.

          (D)  For the purpose of this Condition, any change in:

               (i)  the beneficial ownership of the Debentureholder (whether or
                    not the registered holder of the Debenture is changed); or

               (ii) the ultimate control of the Debentureholder

               shall be regarded as a transfer of the Debentures, and the
               Debentureholder shall procure that the conditions, requirements
               and other provisions regarding transfer under this Condition
               shall be followed and complied with by the beneficial owner of
               the Debentures and by its ultimate controller and ultimate
               beneficial shareholder accordingly.


          5.   INTEREST
               --------

          (A)  Subject to Condition 5(B) below, the Debentures will bear
               interest from the date of issue on the principal amount of the
               Debentures outstanding from time to time at the rate of the
               higher of (i) 5 per cent. per annum (net of withholding tax, if
               applicable) and (ii) such percentage of the dividend yield
               calculated by reference to dividing the annual dividend declared
               per Share by the Conversion Price. The interest will, subject as
               provided herein, be payable by the Company quarterly in arrears
               on dates falling three months, six months, nine months, one year,
               one year and three months, one year and six months, one year and
               nine months and two years, two years and three months, two years
               and six months, two years and nine months after the date of issue
               of the Debenture.

          (B)  In the event that the Debentureholder has converted part or whole
               of the principal amount of the Debentures into Shares, the
               Debentureholder shall be entitled to interest in respect of such
               part or whole of the principal amount for the period from the
               last preceding interest payment date (or the date of issue of the
               Debenture, as the case may be) up to the Conversion Date
               concerned.

                                      41

 
          6.   PAYMENTS
               --------

          (A)  Payment of the interest and principal (if any) in respect of the
               Debentures shall be made on the due dates into such bank account
               as the Debentureholder may notify the Company in writing from
               time to time. All payments by the Company shall be made in United
               States dollars.

          (B)  If the due date for payment of any amount in respect of the
               Debentures is not a Payment Business Day, the Debentureholder
               will be entitled to payment on the next following Payment
               Business Day in the same manner together with interest accrued in
               respect of any such delay.


          7.   CONVERSION
               ----------

          (A)  CONVERSION RIGHT

          (a)  The Conversion Right: Subject as hereinafter provided, the
               Debentureholders have the right to convert the whole or part of
               the principal amount of the Debentures into Shares at any time
               and from time to time, from the date of issue of the Debenture up
               to the close of business on the Maturity Date in amounts of not
               less than US$250,000 (and in integral multiples thereof) on each
               conversion. The Company shall procure that such Shares be issued
               by SAI upon the exercise of such right hereunder.

          (b)  Number of Shares: The number of Shares to be issued on conversion
               of a Debenture will be determined by dividing the principal
               amount of the Debenture to be converted by the Conversion Price
               in effect at the Conversion Date (both as hereinafter defined).
               On conversion the right of the converting Debentureholder to
               repayment of the principal amount of the Debentures being
               converted shall be extinguished and released, and in
               consideration and in exchange therefor SAI shall allot and issue
               Shares credited as paid up in full as provided in this Condition.
               A Conversion Right may be exercised in respect of one or more
               Debentures. If more than one Debenture held by the same holder is
               converted at any one time by the same holder, the number of
               Shares to be issued upon such conversion will be calculated on
               the basis of the aggregate principal amount of the Debentures to
               be converted.

          (c)  Fractions of Shares: Fractions of Shares will not be issued on
               conversion. Notwithstanding the foregoing, SAI will upon
               conversion of Debenture pay in cash in United States dollars a
               sum equal to such portion of the principal amount of the
               Debenture or Debentures evidenced by the Certificate deposited in
               connection with the exercise of Conversion Rights as corresponds
               to any fraction of a Share not issued as a result if such sum
               exceeds US$10.

                                      42

 
          (d)  Conversion Price:  The price at which Shares will be issued upon
               conversion (the "CONVERSION PRICE") will initially be US$5.00 per
               Share but will be subject to adjustment in the manner provided in
               this Condition.

          (e)  Meaning of "Shares": As used in these Conditions, the expression
               "SHARES" means shares of SAI listed and traded on NASDAQ or
               shares of any class or classes resulting from any subdivision,
               consolidation or re-classification of those shares, which as
               between themselves have no preference in respect of dividends or
               of amounts payable in the event of any voluntary or involuntary
               liquidation or dissolution of SAI.

          (f)  Conversion Date: The conversion date in respect of a Debenture
               must fall at a time when the Conversion Right attaching to the
               Debenture 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 Certificate in respect of such
               Debenture and the delivery of such Conversion Notice (as defined
               below).

          (g)  Status of Conversion Shares: The Shares issued upon conversion of
               the Debenture will in all respects rank pari passu with the
               Shares in issue on the relevant Registration Date (as defined
               below). Save as set out in these Conditions, a holder of Shares
               issued on conversion of Debenture shall not be entitled to any
               rights the record date for which precedes the relevant
               Registration Date.

          (B)  CONVERSION PROCEDURE

          (a)  Conversion Notice: To exercise the Conversion Right attaching to
               any Debenture, the holder thereof must complete, execute and
               deposit during normal business hours at the specified office of
               the Company a notice of conversion (a "CONVERSION NOTICE"). The
               Conversion Notice must state a certification as contained in
               Schedule 6 of the Subscription Agreement.

          (b)  Registration: As soon as practicable, and in any event not later
               than 7 days after the Conversion Date, SAI will, in the case of
               Debentures converted on exercise of the Conversion Right and in
               respect of which a duly completed Conversion Notice has been
               delivered and the relevant Certificate and amounts payable by the
               relevant Debentureholder deposited as required, register the
               person or persons designated for the purpose in the Conversion
               Notice as holder(s) of the relevant number of Shares in its Share
               register and will cause its share registrar to mail, such
               certificate or certificates to the person and at the place
               specified in the Conversion Notice, together with any other
               securities, property or cash required to be delivered upon
               conversion and such assignments and other documents (if any) as
               may be required by law to effect the transfer thereof. The person
               or persons will become the holder of record of the number of
               Shares issuable upon 

                                      43

 
               conversion with effect from the date he is or they are registered
               as such in the SAI's register of members (the "REGISTRATION
               DATE").

          (c)  Subsequent Adjustments: Debentures which are converted will be
               cancelled by removal of the Debentureholder's name from the
               register of Debentureholders on the relevant Registration Date.
               If the Conversion Price is adjusted with effect (retroactively or
               otherwise) from a date falling on or before the Registration Date
               of any Shares issued on conversion of a Debenture the
               Debentureholder's entitlement to which was arrived at on the
               basis of the unadjusted Conversion Price, SAI will procure that
               the provisions of this sub-paragraph shall be applied, mutatis
               mutandis, to the number of additional Shares which would have
               been required to be issued on conversion of such Debenture if the
               relevant adjustment had been given effect to as at the Conversion
               Date.

          (C)  ADJUSTMENTS IN CONVERSION PRICE

               The Conversion Price shall from time to time be adjusted in
               accordance with the following relevant provisions and if the
               event giving rise to any such adjustment shall be such as would
               be capable of falling within more than one of the following sub-
               paragraphs, it shall fall within the first of the applicable
               paragraphs to the exclusion of the remaining paragraphs:

               (a)  If and whenever the SAI Shares by reason of any
                    consolidation or sub- division become of a different nominal
                    amount (par value), the Conversion Price in force
                    immediately prior thereto shall be adjusted by multiplying
                    it by the revised nominal amount (par value) and dividing
                    the result by the former nominal amount(par value). Each
                    such adjustment shall be effective from the close of
                    business in Hong Kong on the day immediately preceding the
                    date on which the consolidation or sub-division becomes
                    effective.

               (b)  If and whenever SAI shall issue any SAI Shares (except if
                    such issue is made as a result of an election to receive
                    scrip instead of cash dividend provided that if such scrip
                    is valued at the closing market price of the SAI Share on
                    the date the dividend is declared) credited as fully paid by
                    way of capitalisation of profits or reserves (including any
                    share premium account and capital redemption reserve fund),
                    the Conversion Price in force immediately prior to such
                    issue shall be adjusted by multiplying it by the aggregate
                    nominal amount of the issued and paid up SAI Shares
                    immediately before such issue and dividing the result by the
                    sum of such aggregate nominal amount and the aggregate
                    nominal amount of the SAI Shares issued in such
                    capitalisation. Each such adjustment shall be effective (if
                    appropriate retroactively) from the commencement of the day
                    next following the record date for such issue.

                                      44

 
               (c)  If and whenever SAI shall make any Capital Distribution (as
                    defined below) to holders of SAI Shares (in their capacity
                    as such) (whether on a reduction of capital or otherwise)
                    the Conversion Price in force immediately prior to such
                    distribution shall be adjusted by multiplying it by the
                    following fraction:-

                                         A - B
                                         -----
                                           A

                    where:

                    A   =     the closing market price (as defined below) per
                              SAI Share on the dealing date immediately
                              preceding the date on which the Capital
                              Distribution is publicly announced or (failing any
                              such announcement) the day preceding the date of
                              the Capital Distribution; and

                    B   =     the fair market value on the day of such
                              announcement or if no such announcement was made
                              (as the case may require) the day before the date
                              of the Capital Distribution, as determined by an
                              independent merchant bank or such professional
                              adviser jointly approved by SAI and the Majority
                              Investors of that portion of the Capital
                              Distribution or of such rights which is
                              attributable to one Share,

                    such adjustment shall be effective (if appropriate
                    retroactively) from the commencement of the day next
                    following the record date for the Capital Distribution.

               (d)  If and whenever SAI shall offer to holders of SAI Shares new
                    Shares for subscription by way of rights, or shall grant to
                    holders of Shares any options or warrants to subscribe for
                    new SAI Shares, at a price which is less than the lower of
                    the market price and the Conversion Price at the date of the
                    announcement of the terms of the offer or grant, the
                    Conversion Price shall be adjusted by multiplying the
                    Conversion Price in force immediately before the date of the
                    announcement of such offer or grant by the following
                    fraction:-

                                         C + D
                                         -----
                                         C + E

                    where:

                                      45

 
                    C   =     the number of SAI Shares in issue immediately
                              before the date of such announcement;

                    D   =     the number of SAI Shares which the aggregate of
                              the two following amounts would purchase at the
                              lower of such market price and the Conversion
                              Price:

                              (a)   the total amount (if any) payable for the
                                    rights, options or warrants being offered or
                                    granted; and

                              (b)   the total amount payable for all of the new
                                    SAI Shares being offered for subscription or
                                    comprised in the options or warrants being
                                    granted; and

                    E   =     the aggregate number of SAI Shares offered for
                              subscription or comprised in the options or
                              warrants being granted.

                    Such adjustment shall become effective (if appropriate
                    retroactively) from the commencement of the day next
                    following the record date for the relevant offer or grant.

                    (e) (aa)  If and whenever SAI shall issue wholly for cash
                              any securities which by their terms are
                              convertible into or exchangeable for or carry
                              rights of subscription for new SAI Shares, and the

                              securities, the Conversion Price shall be adjusted
                              by multiplying the Conversion Price in force
                              immediately prior to the issue by the following
                              fraction:

                                      Effective Consideration receivable for

                                      the lower 

                                      46

 
                                      of such market price and the Conversion
                                      Price; and

                                      or exchange rate or subscription price.

                              Such adjustment shall become effective (if
                              appropriate retrospectively) from the close of
                              business in Hong Kong on the Business Day next
                              preceding whichever is the earlier of the date on
                              which the issue is announced and the date on which
                              the issuer determines the conversion or exchange
                              rate or subscription price.


                         (bb) If and whenever the rights of conversion or
                              exchange or subscription attached to any such

                              this sub- paragraph (e) are modified so that the

                              Conversion Price at the date of announcement of
                              the proposal to modify such rights of conversion
                              or exchange or subscription, the Conversion Price
                              shall be adjusted by multiplying the Conversion
                              Price in force immediately prior to such
                              modification the following fraction:

                         Consideration receivable for the securities issued at
                         the modified conversion or exchange price would
                         purchase at the lower of such market price and
                         Conversion Price; and

                          subscription rights conferred by such securities at
                          the modified conversion or exchange rate or
                          subscription price.

                          Such adjustment shall become effective as at the date
                          upon which such modification shall take effect. A
                          right of conversion or exchange or subscription shall
                          not be treated as modified for the foregoing purposes
                          where it is adjusted to take account of rights or
                          capitalisation issues and other events nominally
                          giving rise to adjustment of conversion or exchange
                          terms.

                          EFFECTIVE CONSIDERATION" receivable for the securities
                          issued shall be deemed to be the consideration
                          receivable by SAI for any such securities plus the
                          additional minimum consideration (if any) to be
                          received by SAI upon (and assuming) the conversion or
                          exchange thereof or the exercise of such subscription
                          rights, and the total Effective Consideration per SAI
                          Share initially receivable for such securities shall
                          be such aggregate consideration divided by the number
                          of SAI Shares to be issued upon (and assuming) such
                          conversion or exchange at the initial conversion or
                          exchange rate or the exercise of such subscription
                          rights at the initial subscription price, in each case
                          without any deduction for any commissions, discounts
                          or expenses paid, allowed or incurred in connection
                          with the issue.

                    (f)   If and whenever SAI shall issue wholly for cash any
                          SAI Shares at a price per SAI Share which is less than
                          the lower of the market price and the Conversion Price
                          at the date of the announcement of the terms of such
                          issue, the Conversion Price shall be adjusted by
                          multiplying the Conversion Price in force immediately
                          before the date of such announcement by the following
                          fraction:-


                                             L + M
                                             -----
                                             L + N
 
                          where:
 
                          L    =   the number of SAI Shares in issue immediately
                                   before the date of such announcement;
 
                          M  =     the number of SAI Shares which the aggregate
                                   amount payable for the issue would purchase
                                   at the

                                      48

 
                                   lower of such market price and the
                                   Conversion Price; and
 
                          N   =    the number of SAI Shares in issue immediately
                                   before the date of such announcement plus the
                                   number of SAI Shares so issued.


                          Such adjustment shall become effective on the date of
                          the issue.

                    (g)   If and whenever the cumulative Audited Earnings Per
                          Share ("EPS") for any two consecutive financial years
                          commencing with the financial year ending 1996 and
                          ending with the financial year ending 1998 are less
                          than the corresponding management's projection of
                          cumulative EPS for such years as stated below ("MP"),
                          the Conversion Price shall be adjusted in accordance
                          with the following formula:-

                                                                 MP - EPS
                          Adjusted Conversion Price=US$5.00* [1              ]
                                                                    MP

                          *(Subject to adjustment pursuant to this Condition
                          7(C)(a) to (f) inclusive)

                          where:

                          MP : MP\\1\\ + MP\\2\\ OR MP\\2\\ + MP\\3\\
                          MP\\1\\ : 1996 = US$0.72
                          MP\\2\\ : 1997 = US$1.07
                          MP\\3\\ : 1998 = US$1.61

                    and EPS shall be the EPS for the corresponding financial
                    years.

                    Provided Always:

                    (i)   the Company shall present a certificate showing the
                          calculation and the adjustment to be effected within 7
                          Business Days from the date the audited accounts of
                          SAI for the relevant financial year first becomes
                          available;

                    (ii)  the adjustment occurring in this Condition 7(C)(g)
                          shall become effective on the 14th Business Day
                          following the day the audited accounts of SAI for the
                          relevant financial year first becomes available;

                                      49

 
                    (iii) for the avoidance of doubt, if the Conversion Price
                          has already been adjusted in 1998 in respect of the
                          two financial years ending 1996 and 1997 (the "FIRST
                          ADJUSTED PRICE") and the Conversion Price falls to be
                          further adjusted in 1999 in respect of the two
                          financial years ending 1997 and 1998 (the "SECOND
                          ADJUSTED PRICE"), the second adjustment mentioned
                          hereunder shall also be made on the basis of US$5.00
                          (as adjusted, if relevant, by any of the Condition
                          7(C)(a) to (f) inclusive); and

                    (iv)  if two adjustments fall to be made by virtue of the
                          provisions of this Condition 7(C)(g), the Second
                          Adjusted Price shall prevail over the First Adjusted
                          Price whereupon the First Adjusted Price shall lapse
                          and be of no effect.

          (E)  ADJUSTMENTS DETERMINATION

               (a)  On any adjustment if the relevant Conversion Price is not an
                    integral multiple of one US cent, such shall be rounded down
                    to the nearest US cent.

               (b)  No adjustment shall be made to the Conversion Price where
                    such adjustment (rounded down if applicable) would be less
                    than one per cent. of the Conversion Price then in effect.
                    Any adjustment not required to be made, and any amount by
                    which the Conversion Price has been rounded down, shall be
                    carried forward and taken into account in any subsequent
                    adjustments. Notice of any adjustment shall be given to
                    Debentureholders as soon as practicable after the
                    determination thereof. The Conversion Price may not be
                    reduced so that, on conversion of Debentures, Shares would
                    fall to be issued at a discount to their par value.

               (c)  Where more than one event which gives or may give rise to an
                    adjustment to the Conversion Price occurs within such a
                    short period of time that in

                                      51

 
                    the opinion of the Majority Investors the provisions at
                    Condition 7(C) 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
                    provisions at Condition 7(C) as may be advised by the
                    Majority Investors to be in their opinion appropriate in
                    order to give such intended result.

          (d)       No adjustment involving an increase in the Conversion Price
                    will be made, except in the case of a consolidation of the
                    Shares as referred to above or in the case of adjustment
                    under Condition 7(C)(g) above or in the case to correct an
                    error in a previous calculation of the Conversion Price.

          (e)       In any circumstances where any of the Debentureholders shall
                    not agree with the adjustment to the Conversion Price
                    whether as regards to the basis upon which adjustment has
                    made or as regards the effective date, the Majority
                    Investors may appoint an independent merchant bank or such
                    professional adviser jointly approved by SAI and the
                    Majority Investors to consider how the adjustment should be
                    appropriately done to reflect the relative interest of the
                    persons affected thereby and such determination shall modify
                    or nullify the adjustment accordingly.

          (f)       Whenever the Conversion Price falls to be adjusted, the
                    Company shall prepare such adjustments as soon as
                    practicable but in any event no later than 7 days after the
                    occurrence of the relevant adjustment event (except in
                    relation to an event occurring under Condition 7(C)(g)
                    hereunder in which case the provisions thereunder shall
                    apply) and give notice to the Debentureholders that the
                    Conversion Price has been adjusted and shall at all times
                    thereafter for so long as the Debentures remains outstanding
                    make available for inspection at the principal place of
                    business of the Company a copy of the certificate signed by
                    an independent director of SAI setting forth details of the
                    event giving rise to the adjustment.


     8.   PROCEDURE FOR CONVERSION

          The Conversion Rights pursuant to Condition 7(A) may, subject as
          provided herein, be exercised on any Business Day prior to
          maturity of the Debenture by the Debentureholder delivering to
          the principal place of business of the Company in Hong Kong a
          written notice stating the intention of the Debentureholder to
          convert and the address for the delivery of the share
          certificates of the Conversion Shares pursuant to 7(B) together
          with the Certificate. The Company shall be responsible for
          payment of all taxes and stamp duty, issue and registration
          duties (if any) and levies and charges (if any) arising on any
          such conversion.

                                      52

 
     9.   REDEMPTION


     10.  UPON MATURITY

          Unless previously redeemed or converted or purchased and
          cancelled as provided herein, the Company will redeem each
          Debenture on the Maturity Date at its principal amount
          outstanding together with any accrued but unpaid interest
          calculated up to and including the date of payment together with
          an amount that would enable the Debentureholder to yield in
          aggregate an internal rate of return ("IRR") of 12% per annum on
          the costs of its investment. For this purpose, the internal rate
          of return shall bear the same meaning as defined in Condition
          11(C). Redemption upon maturity is mandatory and automatic
          without service of any notice. The Company can not redeem the
          Debentures in whole or in part at its option prior to the
          Maturity Date.

     (A)  Upon the occurrence of an Event of Default

          Upon the occurrence of an Event of Default, the Company shall
          redeem the whole of or part of the Debentures as shall be
          required by virtue by the Debentureholders in such manner as
          specified in Condition 11 below.

     (B)  Upon the occurrence of certain event of adjustment

          (a)  In the event that an adjustment arising by virtue of an
               event described in Condition 7(C)(g) occurs and such
               adjustment would result in (i) the number of Shares that
               would have been issued to the Funds in aggregate had
               Conversion immediately taken place or (ii) the number of
               Shares that would have been issued to any one of the
               Investors had Conversion immediately taken place to exceed
               20% of the Deemed Total Issued Share Capital of SAI
               (including also for this purpose such number of Shares that
               would have been issued upon Conversion of all of the
               Debentures), that portion of the Debenture(s) representing
               the excess of such Shares over such 20% ("THE EXCESS") (as
               defined below) shall, at the option of the relevant
               Debentureholder, be redeemed by the Company at its principal
               amount outstanding together with any accrued but unpaid
               interest calculated up to and including the date of payment
               together with an amount that would enable the
               Debentureholder to yield in aggregate an IRR (as defined
               below) of 19.75% per annum. The Debentureholders shall
               exercise this right by service of a notice on the Company
               and the Company shall promptly make payment within 45 days
               after receipt of such notice.

          (b)  For the purpose of this Condition, Excess shall be
               calculated as follows:
               
                                      53

 
               Q (PIE)  (R(PIE) S)
                 
               where:

               Q   =   principal amount of the Debentures outstanding held
                       by the Funds or the Investor (not being a Fund) as
                       the case may be

               R   =   Conversion Price, as adjusted by virtue of Condition
                       7(C)(g)

               S   =   the number of Shares that need to be issued upon
                       conversion of the Debentures in order to give a
                       twenty percent (20%) holding by the Funds in
                       aggregate or the Investor (not being a Fund) as
                       the case may be of the Deemed Total Issued Share
                       Capital of SAI (including also for this purpose
                       such number of Shares that would have been issued
                       upon Conversion of all of the Debentures)

     (D)  All Debentures which are redeemed, converted or purchased by the
          Company will forthwith be cancelled.


      11. Protection of the Debentureholder

          The Guarantors and ACL have undertaken certain matters in the
          Subscription Agreement for the protection of the Debentureholders
          for so long as any of the Debentures remains outstanding.

     12.  Events of default

          (A)  If any of the following events ("EVENT OF DEFAULTS") occurs
               each of the Debentures shall automatically become
               immediately due and payable in full by the Company at its
               principal amount outstanding together with any accrued but
               unpaid interest calculated up to and including the date of
               payment together with an amount that would enable the
               Debentureholder to yield in aggregate IRR on its cost of
               investment of 19.75% per annum unless the Company shall have
               received a notice from any of the Debentureholders to the
               effect that such redemption shall only be in respect of part
               of the Debentures held by that Debentureholder in which case
               the amount payable hereunder shall only be in relation to
               that part of the Debentures that Debentureholder wishes to
               redeem.

                                      54

 
          (B)  An Event of Default occurs when:-

          (a)  the listing of the Shares (as a class) on NASDAQ:-

               (i)  ceases;

               (ii) is suspended for a continuous period of 90 days on each
                    of which NASDAQ is generally open for trading, such
                    suspension having occurred by any reason whatsoever; or

          (b)  SAI or the Company fails to obtain a listing or
               authorisation for quotation of the Conversion Shares on
               NASDAQ; or

          (c)  the Company or any of the Guarantors or ACL defaults in
               performance of any of its obligations contained in the terms
               and conditions of the Debenture or the Subscription
               Agreement or the ACL Undertaking, and such event to the
               extent it can be remedied continues to subsist for a
               continuous period of 30 days after notice of such event is
               given from the Majority Debentureholders to the Company; or

          (d)  there is default in the payment of principal or the premium
               (if any) or interest on any of the Debenture within seven
               (7) days in the case of principal or premium of fourteen
               (14) days in the case of interest from the due date for
               payment; or

          (e)  any Indebtedness of a material nature for borrowed money of
               any member of the SAI Group becomes due and repayable
               prematurely by reason of an event of default (however
               described) or any member of the SAI Group fails to make any
               payment in respect of any Indebtedness for borrowed money of
               the due date for payment as extended by any originally
               applicable grace period or any security given by any of them
               for any Indebtedness for borrowed money becomes enforceable
               or if any default is made by any of them in making any
               payment due under any guarantee and/or indemnity given by it
               in relation to any Indebtedness for borrowed money of any
               other person and such occurrence has or will have in the
               opinion of the Majority Debentureholders a materially
               adverse impact on any member of the SAI Group; or

          (f)  any legal process is levied or enforced or sued out upon or
               against any part of the property, assets or revenues of any
               member of the SAI Group which in the opinion of the Majority
               Debentureholders has a materially adverse effect upon any of
               them, and is not discharged or stayed within 60 days (or
               such longer period as the Majority Debentureholders may
               consider appropriate in relation to the jurisdiction
               concerned) of having

                                      55

 
               been so levied, enforced or sued out unless and for so long as
               the Majority Debentureholders is satisfied that it is being
               contested in good faith, diligently and with a reasonable
               prospect of success by legal action; or

          (g)  an encumbrancer takes possession or a receiver, manager or
               other similar officer is appointed of, or an attachment
               order is issued in respect of, the whole or any part of the
               undertaking, property, assets or revenues of any member of
               the SAI Group or of ACL which in the opinion of the Majority
               Debentureholders has a materially adverse effect upon any of
               them; or

          (h)  any member of the SAI Group is unable to pay its debts as
               they mature or takes any proceeding under any law for a
               readjustment or deferment of its obligations or any part of
               them or makes or enters into a general assignment or an
               arrangement or composition with or for the benefit of its
               creditors which in the opinion of the Majority
               Debentureholders has a materially adverse effect upon any of
               them; or

          (i)  an order of a court of competent jurisdiction is made or an
               resolution passed for the winding up or
               dissolution or administration of any member of the SAI Group
               or of ACL, ceases or threatens to cease to carry on all or
               substantially all of its business or any of them stops or
               threatens to stop payment (within, if applicable, the
               meaning of the bankruptcy law of any appropriate
               jurisdiction) or applies for or consents to or suffers the
               appointment of an administrator, liquidator or receiver over
               the whole or any material part of the undertaking, property,
               assets or revenues of or any of them; or

          (j)  proceedings shall have been initiated against ACL or any
               member of the SAI Group under any applicable bankruptcy,
               insolvency or reorganisation law and such proceedings shall
               not have been discharged or stayed within a period of 60
               days (or such longer period as the Funds may consider
               appropriate in relation to the jurisdiction concerned)
               unless and for so long as the Majority Debentureholders is
               satisfied that it is being contested in good faith,
               diligently and with a reasonable prospect of success by
               legal action; or

          (k)  any event occurs which under the laws of any relevant
               jurisdiction and in the opinion of Majority Debentureholders
               has an analogous effect to any of the event referred to in
               any of the foregoing paragraphs; or

          (l)  the EPS (as defined in the Condition 7(D)) of SAI for any of
               the financial years falling between the financial year ended
               31st December, 1995 and the Maturity Date is less than
               US$0.55; or
              
                                      56

 
          (m)  if:

               (i)  at the end of each quarter of a financial year ("QUARTER
                    DATE"), the trade debts (after provisions) left outstanding
                    relating to the sales achieved in a period occurring
                    immediately before the 12- month period preceding the
                    relevant Quarter Date is or exceeds 10 percent of net sales
                    achieved by SAI in the 12 months immediately preceding the
                    relevant Quarter Date; or

               (ii) at the end of each Quarter Date, the trade debts (after
                    provisions) left outstanding relating to the sales
                    achieved in a 12-month period immediately preceding the
                    Quarter Date is or exceeds 40 per cent of the net sales
                    achieved by SAI in the same period of time and such
                    outstanding debts are not accordingly repaid or
                    remedied to fall below the 10 per cent or 40 per cent
                    level as the case may be within 30 days after the
                    elease of the 10-Q Quarterly Report or the 10-K Annual
                    Report. The first of the Quarter Dates shall commence
                    on 31st December, 1996.

     (C)  For the purpose of this Debenture, IRR is the annual internal
          rate of return compounded on a quarterly basis, which is the
          discount rate at which the present value of future cash flows,
          including proceeds from interest, dividends and transfer / sale
          of the Debentures and any repayment of the principal amount of
          the Debentures outstanding is equal to the initial subscription
          amount of all the Debentures subscribed and is calculated in
          accordance with the following formula:-


 
          OI   =    (D1 + C1) + (D2 + C2) + (D3 + C3) + ... +(Dn + Cn)+  
                    ---------   ---------   ---------       --------- 
                                                                   Pn
                                                                   --
                    1 + R      (1 + R)/2/  (1 + R)/3/   (1 + R)/n/  (1 + R)/n/

 
          Where:
 
          Pn   =    the amount to be paid by the Company to the Debentureholder
                    on the day of payment for redemption, provided always that
                    Pn shall not be less than zero;

          OI   =    the price of the Debenture paid by the Debentureholder for
                    the Debenture pursuant to the Subscription Agreement;

          Cn   =    (if applicable) the amount of any capital repayment or
                    reduction made during the quarter denoted by "n";

                                      57

 
          Dn   =    the amount or value of any interest or other money paid with
                    respect to the outstanding Debentures during the quarter
                    denoted by "n";

          n    =    the number of complete quarters from the issue date of
                    the Debentures to the date of redemption; and

          R    =    the quarterly internal rate of return in the event of
                    redemption of the Debentures which shall be 4.61%
                    (given an annual internal rate of return of 19.75% per
                    annum) and shall be 2.87% (given an annual internal
                    rate of return of 12% per annum)

          and for the purposes of this calculation only, all cashflows
          (denoted by Pn, Dn or Cn) shall be deemed to arise on the last
          day of the quarter in which they occur or are paid.

     (D)  In this Condition 11:

          (a)  the determination of "materiality", "material" or "materially"
               shall be by the Majority Debentureholders and in the event of
               disagreement of or any disputes over the applicability or the
               interpretation of the occurrence of any such events as described
               in Condition 11(B)(e), (f), (g), (h), (i), (j) or (k), an
               independent professional adviser (including a merchant bank of
               repute, an international firm of accountants or legal adviser)
               shall be appointed by the Company from a selection of three (3)
               names given by the Majority Debentureholders to the Company who
               shall determine the same and whose decision shall be final and
               binding;

          (b)  "Majority Debentureholders" shall mean the majority of the
               Debentureholders in value holding more than 50% of the total
               principal amount of the Debentures outstanding.


     12.  VOTING

          The Debentureholder will not be entitled to receive notices of,
          attend or vote at any meetings of the Company by reason only of
          it being the Debentureholder.


     13.  REGISTER

          The Company shall maintain a register in Bermuda or in Hong Kong
          of the particulars of the Debenture and the Debentureholder.

          14.  REPLACEMENT NOTE

               If any of the Debentures is lost or mutilated the Debentureholder
               shall forthwith notify the Company and a replacement Debenture
               shall be issued if the Debentureholder provides the Company with:
               (1) the mutilated Debenture; (ii) a declaration by the
               Debentureholder or its officer that the Debenture had been lost
               or mutilated (as the case may be) or other evidence that the
               Debenture had been lost or mutilated; and (iii) an appropriate
               indemnity in such form and content as the Company may reasonably
               require. Any Debenture replaced in accordance with this Condition
               shall forthwith be cancelled.
