          STATUS AND CHARACTERISTICS OF THE SECURITIES ISSUED BY SAI
          ----------------------------------------------------------


1.   SERIES A WARRANTS
     -----------------

     SAI has outstanding an aggregate of 10,392,167 Series A Warrants (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.

2.   SERIES A PREFERRED STOCK
     ------------------------

     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
     ------------------------

     To the extent that the holders do not elect to redeem the shares of Series
     B Preferred Stock in connection with a public offering of SAI Common Stock,
     the Series B Preferred Stock is convertible into Common Stock on the basis
     of 100 shares of Common Stock for each share of Series B Preferred Stock.
     If, by the date which is two years after the date on which the shares of
     Series B Preferred Stock are distributed to the holders, such holders have
     not been able to redeem their shares because SAI has not made a public
     offering as specified, the Series B Preferred Stock will be automatically
     converted into shares of Common Stock on the following basis: On the first
     business day following the expiration of the two year period, each share is
     to be automatically converted into that number of shares of Common Stock
     that equals $500.00 divided by the lesser of $5.00 or the average closing
     price of SAI Common Stock computed by taking the then most recent 60
     consecutive trading days when SAI Common Stock is traded at a minimum
     volume of 2,000 shares per day for 45 of those 60 consecutive trading days.

     US$250,000 each. Debenture certificate(s) (each a "CERTIFICATE") will be
     issued to each Debentureholder in respect of its registered holding(s) of
     Debenture(s). Each Debenture and each Certificate will be numbered serially
     with an identifying number which will be recorded on the relevant
     Certificate and in the register of Debentureholder kept by the Company.

(C)  TITLE

     Title to the Debentures passes only by registration in the register of
     Debentureholders. The holder of any Debenture will (except as otherwise
     required by law) be treated as its absolute owner for all purposes (whether
     or not it is overdue and regardless of any notice of ownership, trust or
     any interest in it or

                                      38
<PAGE>
 
     any writing on, or the theft or loss of, the Certificate issued in respect
     of it) and no person will be liable for so treating the holder.

3.   NEGATIVE PLEDGE
     ---------------

     The Company, SAI, CIBHL, SPC and ACL have given in the Subscription
     Agreement certain negative pledges over creation of Securities Interest (as
     defined in the Subscription Agreement) for so long as any of the Debentures
     remains outstanding.

4.   TRANSFERS OF DEBENTURES; ISSUE OF CERTIFICATES
     ----------------------------------------------

(A)  TRANSFER

     (i)   No Debentures may be transferred by any Debentureholders unless such
           transfer is in accordance with the provisions of (A)(ii) below.

     (ii)  Debentures held by any of the Investors may be transferred at any
           time provided that:

           (a)  such proposed transfer is in respect of half of or the entire
                amount of the principal amount of the Debentures then
                outstanding and held by that Investor or in the case of the
                Investor being a Fund, the Funds taken together in aggregate. No
                other transfer of any other amounts shall be allowed unless with
                the approval of the Company;

           (b)  the Certificate(s) evidencing the Debenture(s) with the form of
                transfer duly completed and signed shall have been lodged with
                the specified office of the Company in accordance with the
                provisions at (iii) below; and

           (c)  (in the event of a transfer by any of the Funds only) if the
                proposed transfer is to a transferee outside the HSBC Group (as
                defined below) such transfer must specify that the transferee
                shall not have assigned to it nor in any way enjoy or benefit
                from the various rights relating to management hitherto enjoyed
                by and granted to the Funds pursuant to the Subscription
                agreement.

     (iii) (a)  the form of transfer shall be in a form previously agreed
                between the Company and the Debentureholders and shall be
                executed under the hand of the transferor and the transferee (or
                their duly authorized representatives) or, where either the
                transferor or

                                      39
<PAGE>
 
                transferee is a corporation, under its common seal (if any) and
                under the hand of one of its officers duly authorized in writing
                or otherwise executed by a duly authorized officer thereof. In
                this Condition "transferor" shall, where the context permits or
                requires, include joint transferors or can be construed
                accordingly.

           (b)  the Certificate of the Debenture must be delivered for
                registration to the Company accompanied by (i) a duly executed
                form of transfer; (ii) 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; (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 1933 or under the
           securities laws of any other jurisdiction, the Debentures and the
           Conversion Shares must not be sold unless such securities are
           registered under the Securities Act of 1933, or an exemption from the
           registration requirements of the Securities Act of 1933 is available.
           SAI may cause the certificate or certificates evidencing all or any
           of the Conversion Shares to bear a legend to that effect.

     (v)   For the purposes of this Condition 4(A), "HSBC GROUP" shall mean any
           company or entity which is at any time a member of the Hongkong Bank
           Group or which (or the holding company of which) has its operation
           managed by a member of the Hongkong Bank Group and "HONGKONG BANK
           GROUP" means HSBC Holdings PLC and its subsidiaries.

(B)  DELIVERY OF NEW CERTIFICATES

     Subject to compliance with applicable securities laws and regulations, the
     Company shall, within 7 Business Days of receipt of such documents from the
     Debentureholder, cancel the existing 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
<PAGE>
 
(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.

6.   PAYMENTS
     --------

                                      41
<PAGE>
 
(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
<PAGE>
 
(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
<PAGE>
 
     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
<PAGE>
 
     (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 
<PAGE>
 
           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 total Effective Consideration per SAI
                     Share (as defined below) initially receivable for such
                     securities is less than the lower of the market price and
                     the Conversion Price at the date of the announcement of the
                     terms of issue of such securities, the Conversion Price
                     shall be adjusted by multiplying the Conversion Price in
                     force immediately prior to the issue by the following
                     fraction:

                             F + G
                             -----
                             F + H

                     where:

                     F   =   the number of SAI Shares in issue immediately
                             before the date of the issue;

                     G   =   the number of SAI Shares which the total Effective
                             Consideration receivable for the securities issued
                             would purchase at the lower

                                      46
<PAGE>
 
                             of such market price and the Conversion Price; and

                     H   =   the number of SAI Shares to be issued upon
                             conversion or exchange of, or the exercise of the
                             subscription rights conferred by, such securities
                             at the initial conversion 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 securities as are
                     mentioned in section (aa) of this sub- paragraph (e) are
                     modified so that the total Effective Consideration per SAI
                     Share initially receivable for such securities shall be
                     less than the lower of the market price and 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:

                             I + J

                     I + K

        where:

               I = the number of SAI Shares in issue immediately before the date
               of such modification;

               J = the number of SAI Shares which the total Effective
               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

               K = is the number of SAI Shares in issue immediately before such
               date of modification plus the number of SAI Shares to be issued

                                      47
<PAGE>
 
               upon conversion or exchange of or the exercise of the
               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.

               For the purposes of this sub-paragraph (e), the "TOTAL 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     =   amount payable for the issue would purchase at the
                         lower of such market price and the Conversion the
                         number of SAI Shares which the aggregate Price; and
 
                                      48 
<PAGE>
 
               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;

          (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

                                      49
<PAGE>
 
                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.

          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 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

          may be advised by the Majority Investors to be in their opinion

     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

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.

9.   REDEMPTION


10.  UPON MATURITY

                                      52
<PAGE>
 

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:

     Q = (R/S)

     where:

                                      53
<PAGE>
 
     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.

(B)  An Event of Default occurs when:-

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

     (i)  ceases;

     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

     days (or such longer period as the Majority Debentureholders may consider
     appropriate in relation to the jurisdiction concerned) of having

     diligently and with a reasonable prospect of success by legal action; or

(g)  an encumbrancer takes possession or a receiver, manager or other similar

<PAGE>
 
     whole or any part of the undertaking, property, assets or revenues of

(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";
 
     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 

                                      57
<PAGE>
 
           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
