            the TSX for so long as any Subscriber holds any of the Securities;

      (e)   will use its reasonable commercial efforts to obtain Shareholder

<PAGE>

                                     - 10 -

            "Unless permitted under securities legislation, the holder of the

            bear the following legend:

            "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
            THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S.
            SECURITIES ACT"). THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES,
            AGREES FOR THE BENEFIT OF THE CORPORATION THAT SUCH SECURITIES MAY
            BE OFFERED, SOLD OR OTHERWISE TRANSFERRED ONLY (A) TO THE
            CORPORATION, (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE
            904 OF REGULATION S UNDER THE U.S. SECURITIES ACT, (C) IN COMPLIANCE
            WITH THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES ACT
            PROVIDED BY RULE 144 OR RULE 144A THEREUNDER, IF AVAILABLE, OR (D)
            IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S.
            SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, AND THE

            RECOGNIZED STANDING IN FORM AND SUBSTANCE SATISFACTORY TO THE
            CORPORATION TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE MAY NOT
            CONSTITUTE "GOOD DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON STOCK
            EXCHANGES IN CANADA. IF, AT ANY TIME THE CORPORATION IS A "FOREIGN
            ISSUER" AS DEFINED IN REGULATION S UNDER THE U.S. SECURITIES ACT,
            THESE SECURITIES ARE BEING SOLD IN COMPLIANCE WITH RULE 904 OF
            REGULATION S UNDER THE U.S. SECURITIES ACT, A NEW CERTIFICATE
            BEARING NO LEGEND, DELIVERY OF WHICH WILL CONSTITUTE "GOOD
            DELIVERY," MAY BE OBTAINED FROM THE CORPORATION'S TRANSFER AGENT
            UPON DELIVERY OF THIS CERTIFICATE AND A DULY EXECUTED DECLARATION,
            IN A FORM SATISFACTORY TO THE CORPORATION'S TRANSFER AGENT AND THE
            CORPORATION, TO THE EFFECT THAT THE SALE OF THE SECURITIES
            REPRESENTED HEREBY IS BEING MADE IN COMPLIANCE WITH RULE 904 OF
            REGULATION S UNDER THE U.S. SECURITIES ACT";

            provided, that if, at the time the Issuer is a "foreign issuer", as
            that term is defined by Regulation S under the U.S. Securities Act,
            the Securities are being sold in compliance with the requirements of
            Rule 904 of Regulation S, as referred to above, and in compliance
            with Canadian local laws and regulations, the legend may be removed
            by providing a declaration to the Issuer's registrar and transfer
            agent for the Securities in the form attached hereto as Appendix A
            to Schedule "B" (or as the Issuer may prescribe from time to time);
            and

            provided further, that, if any of the Securities are being sold
            pursuant to Rule 144 of the U.S. Securities Act, the legend may be
            removed by delivery to the Issuer's transfer agent of an opinion of
            counsel of recognized standing in form and substance satisfactory to
            the Issuer, to the effect that the legend is no longer required
            under applicable requirements of the U.S. Securities Act or state
            securities laws.

10.3        The Warrants may not be exercised in the United States or by or on
            behalf of, or for the account or benefit of, a U.S. Person or a
            person in the United States unless registered under the U.S.
            Securities Act and any applicable state securities laws or unless an
            exemption from such registration requirements is available; provided
            that a U.S. Accredited Investor that purchased Units in the U.S.
            private placement will not be required to deliver an opinion of
            counsel in connection with the exercise

            of Warrants that are a part of those Units. The certificates
            representing the Warrants, and all certificates issued in exchange
            therefor or in substitution thereof, shall bear the following
            legend:

            ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED UNDER
            THE SECURITIES ACT AND THE APPLICABLE SECURITIES LEGISLATION OF ANY
            SUCH STATE OR AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS IS
            AVAILABLE. "UNITED STATES" AND "U.S. PERSON" ARE AS DEFINED BY
            REGULATION S UNDER THE U.S. SECURITIES ACT."

10.4        The Preferred Shares may not be converted into Common Shares in the
            United States or by, on behalf of, or for the account or benefit of,
            a U.S. Person unless registered under the U.S. Securities Act and
            any applicable state securities laws or unless an exemption from
            such registration requirements is available; provided that a U.S.
            Accredited Investor that purchased Units in the U.S. private
            placement will not be required to deliver an opinion of counsel in
            connection with the conversion of Preferred Shares that are a part
            of those Units. The certificates representing the Preferred Shares,
            and all certificates issued in exchange therefor or in substitution
            thereof, shall bear the following legend:

            "THE SECURITIES REPRESENTED HEREBY AND THE SECURITIES DELIVERABLE
            UPON CONVERSION THEREOF HAVE NOT BEEN REGISTERED UNDER THE UNITED
            STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES
            ACT"), OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES AND
            MAY NOT BE CONVERTED IN THE UNITED STATES OR BY OR ON BEHALF OF, OR

            PERSON" ARE AS DEFINED BY REGULATION S UNDER THE U.S. SECURITIES
            ACT."

10.5        The Subscriber consents to the Issuer making a notation on its
            records or giving instructions to any transfer agent of the
            Securities in order to implement the restrictions on transfer,
            exercise and conversion set forth and described herein.

11.         FEES AND EXPENSES

11.1        Subject to the Company obtaining Shareholder Approval, in
            consideration for services provided to the Company in connection
            with structuring and arranging the Offering, the Company will upon

            Closing: (a) pay to the Agent an amount (the "Investment Banking
            Fee") equal to 7% of the gross proceeds raised through the Agent's
            placement of the Units with subscribers under the Offering; and (b)
            issue to the Agent the number of Broker Warrants calculated by
            dividing 50% of the Investment Banking Fee by CDN$0.85.

<PAGE>

                                     - 12 -

11.3        For greater certainty, in the event that Shareholder Approval is not
            obtained: (a) the Advisory Services Fee and the Investment Banking
            Fee will not be payable and (b) the Company will not be required to
            issue any of the Broker Warrants.

11.4        The Company shall be responsible for the reasonable out-of-pocket
            expenses of the Subscriber and the reasonable legal fees and
            disbursements, together with any applicable tax thereon, of the
            Subscriber's counsel incurred in connection with the Offering up to
            an aggregate maximum of Cdn$75,000 in respect of the foregoing
            expenses and fees of Agent, the Subscriber and all other subscribers
            under the Offering. All such fees and expenses shall be paid
            reasonably promptly by the Company directly to SDS Capital Group
            Inc. and to the Agent, in respect of fees and expenses owing to all
            other subscribers under the Offering, immediately after the receipt
            by the Company of an invoice or invoices detailing such fees and
            expenses.

12.         RESTRICTION ON MANDATORY CONVERSION OF PREFERRED SHARES

12.1        The parties acknowledge that the rights and conditions attached to
            the Preferred Shares stipulate, among other things, that the Company
            may, at its option, require the Subscriber to convert its Preferred
            Shares into Common Shares upon the occurrence of certain events as
            described therein (each a "Triggering Event"). The Company
            acknowledges and agrees that, notwithstanding the occurrence of a
            Triggering Event, it may not exercise its right to require the
            Subscriber to convert its Preferred Shares into Common Shares if the
            number of Common Shares to be issued pursuant to such a conversion
            would exceed, when aggregated with all other Common Shares owned by
            the Subscriber at such time, the number of Common Shares which would
            result in the Subscriber owning more than 4.99% of all of the Common
            Shares outstanding at such time. For the purposes of determining
            whether such percentage ownership would be exceeded as a result of
            such conversion, after a Triggering Event occurs, the Subscriber
            shall deliver to the Company from time to time upon written request
            a sworn declaration or affidavit of the Chief Executive Officer, the
            President or the Chief Financial Officer of the Subscriber (or
            individual holding an equivalent office or position with the
            Subscriber) stipulating the number of Common Shares beneficially
            owned by the Subscriber as of a then current date. For greater
            certainty, if and to the extent that conversion of a portion of the
            Subscriber's Preferred Shares would not result in the Subscriber
            owning more than 4.99% of all of the Common Shares outstanding at
            such time, the Company may exercise its right to require the
            Subscriber to convert such number of Preferred Shares into Common
            Shares as would result in the Subscriber owning up to 4.99% of all
            of the Common Shares outstanding at such time. The Company's
            covenant set out in this section 12.1 is personal to the Subscriber
            and is not assignable by the Subscriber to any transferee, purchaser
            or other subsequent holder of the Subscriber's Preferred Shares.

13.         RESTRICTION ON COMPANY'S RIGHT TO REDEEM WARRANTS

13.1        The parties acknowledge that the rights and conditions attached to
            the Warrants stipulate, among other things, that the Company may, at
            its option, redeem the Warrants upon the Common Shares trading at
            the price and for the period stipulated in the certificate
            representing the Warrants (the "Triggering Event"). The Company
            acknowledges and agrees that, notwithstanding the occurrence of the
            Triggering Event, it may not exercise its right to redeem the
            Warrants if the number of Common Shares to be issued pursuant to
            such a conversion would exceed, when aggregated with all other
            Common Shares owned by the Subscriber at such time, the number of
            Common Shares which would result in the Subscriber owning more than
            4.99% of all of the Common Shares outstanding at such time. For the
            purposes of determining whether such percentage ownership would be
            exceeded as a result of the exercise of the Warrants, after the
            Triggering Event occurs, the Subscriber shall deliver to the Company
            from time to time upon written request a sworn declaration or
            affidavit of the Chief Executive Officer, the President or the Chief
            Financial Officer of the Subscriber (or individual holding an
            equivalent office or position with the Subscriber) stipulating the
            number of Common Shares beneficially owned by the Subscriber as of a
            then current date. For greater certainty, if and to the extent that
            the exercise of a portion of the Subscriber's Warrants would not
            result in the Subscriber owning more than 4.99% of all of the Common
            Shares outstanding at such time, the Company may

                                     - 13 -

            exercise its right to redeem the number of Warrants that, if
            exercised, would result in the Subscriber owning up to 4.99% of all
            of the Common Shares outstanding at such time. The Company's
            covenant set out in this section 13.1 is personal to the Subscriber
            and is not assignable by the Subscriber to any transferee, purchaser
            or other subsequent holder of the Subscriber's Warrants.

14.         RESTRICTION ON SUBSCRIBER'S RIGHT TO CONVERT PREFERRED SHARES OR
            EXERCISE WARRANTS

14.1        Notwithstanding anything to the contrary set forth in this
            Subscription Agreement, at no time may the Subscriber convert the
            Preferred Shares or exercise any Warrants if the number of Common
            Shares to be issued pursuant to such conversion or exercise would
            exceed, when aggregated with all other Common Shares owned by such
            Subscriber at such time, the number of Common Shares which would
            result in such Subscriber owning more than 4.99% of all of the
            Common Shares outstanding at such time; provided, however, that upon
            the Subscriber providing the Company with at least 61 days notice
            (the "Waiver Notice") that such Subscriber is waiving this section
            14 with regard to any or all Common Shares issuable upon conversion
            of the Preferred Shares or the Warrants, this section shall be of no
            force or effect with regard to those Preferred Shares or Warrants
            referenced in the Waiver Notice.

15.         RIGHTS OF FIRST OFFER AND STANDSTILL

15.1        The Company shall deliver notice in writing (a "Financing Notice")
            to the Subscriber, together with all other initial subscribers of
            the Preferred Shares pursuant to the Offering (collectively, the
            "Purchasers") of the material terms and conditions of any further
            equity, equity-linked or debt financing which the Company proposes
            to obtain during a period of 24 months following the Closing. The
            Purchasers collectively shall have the right of first offer to
            provide part or all of any such financing on the terms set out in
            the Financing Notice. Further, in the event such proposed financing
            is to be made at a price (or conversion or exercise price) per
            Common Share at or below Cdn$0.75, the Purchasers collectively shall
            have the right (the "Standstill Right") to cause the Company not to
            complete such financing (such Standstill Right to be exercised by
            the delivery of notice to that effect by Purchasers holding greater
            than 50% of the number of Preferred Shares then outstanding).

15.2        The Purchasers may exercise their right of first offer or Standstill
            Right by notice in writing delivered to the Company within 10 days
            after receipt of the Company's Financing Notice. The Purchasers'
            notice shall (i) stipulate the amount of the financing which the
            Purchasers individually and collectively will provide, or (ii) state
            that the Purchasers wish to exercise their Standstill Right. If the
            financing proceeds, the Purchasers shall be entitled to participate
            in the financing on a pro-rata basis in proportion to their
            percentage participation in the Offering, or in such other
            proportions as they, in consultation with the Issuer, may mutually
            agree upon.

15.3        If a Purchaser fails to give notice within the time stipulated in
            section 15.2 that it will provide all or any portion of such
            financing on the terms set out in the Financing Notice, or if the
            requisite number of Purchasers fail to give notice of exercise of
            the Standstill Right, the Company will have the right to make other
            arrangements to obtain such financing from other sources, provided
            that such financing is provided on terms no less favourable to the
            Company than those set out in the Company's Financing Notice.

15.4        The Purchaser's right of first offer and Standstill Right herein
            will not terminate if the Purchaser fails to exercise such rights
            with respect to any proposed financing, and will continue in force
            with respect to any subsequent proposed financing described in
            section 15.1 for the period stipulated therein.

15.5        Notwithstanding section 15.1, the right of first offer and
            Standstill Right granted to the Subscriber hereunder shall not apply
            to the issuance of any securities by the Company in connection with
            an acquisition, strategic partnership, joint venture or other
            business combination, any public "bought deal" underwritten
            offering, or any vendor take-back debt financing in connection with
            any acquisition.

16.         RESTRICTIONS ON ISSUANCES OF SECURITIES AND DEBT OBLIGATIONS

16.1        The Company will not issue any securities or incur any debt
            obligations (other than liabilities incurred in the ordinary course
            of business such as trade payables; Technology Partnerships Canada
            payables; wages, vacation, flextime and commissions payable;
            employee taxes, CPP and EI payable; customer payments in excess of
            revenue; federal excise and goods and services taxes payable;
            provincial sales tax payable; and Workers' Compensation payable, and
            liabilities of a similar nature) ranking in any way senior to or
            pari passu with the Preferred Shares without the prior written
            approval of the Subscriber, such approval not to be unreasonably
            withheld. If the Company proposes to issue any securities or incur
            any debt obligations, it shall deliver a notice in writing to the
            Subscriber setting out the material terms and conditions of the
            proposed transaction, the identities of the proposed participants in
            the transaction (if known) and the principal reasons for such
            transaction. The Subscriber shall, within 10 days of receipt of such
            notice, deliver notice in writing to the Company indicating whether
            it is consenting to the proposed transaction and, if not, the reason
            or reasons for refusing its consent. The right granted to the
            subscriber hereunder is personal to the Subscriber and may not be
            assigned to any transferees, purchaser or subsequent holders of the
            Subscriber's Preferred Shares other than affiliates (as defined in
            the Business Corporations Act (British Columbia)) and associates (as
            defined in the Securities Act (British Columbia)) of the Subscriber.
            If and when more than 90% of the Preferred Shares originally issued
            are converted or redeemed, or the Purchasers (as defined in Section
            15) and their respective associates and affiliates otherwise
            collectively cease to hold at least 10% of the number of Preferred
            Shares originally issued under the Offering, the approval of the
            Subscriber will no longer be required. The requirement for such
            approval shall also not apply with respect to any increase in the
            Company's operating line with its current bank or any other major
            commercial bank or combination of banks provided that the total
            borrowing ceiling for the operating line or lines established by the
            Company and its subsidiaries does not exceed 15% of the Company's
            then current consolidated annual gross revenues.

17.7        This Subscription Agreement may be signed by the parties in as many
            counterparts as may be deemed necessary, each of which so signed

17.8        This Subscription Agreement, including, without limitation, the
            representations, warranties, acknowledgements and covenants
            contained herein, shall survive and continue in full force and

            completion of the purchase of the Units by the Subscriber pursuant
            hereto.

17.9        The invalidity or unenforceability of any particular provision of
            this Subscription Agreement shall not affect or limit the validity

            warranties, whether expressed, implied, oral or written, by statute,
            by common law, by the Issuer, by the Subscriber, or by anyone else.
            If there is any conflict between the provisions of this Subscription
            Agreement and the provisions of the Term Sheet attached hereto as

            certificates representing the Warrants or Broker Warrants, as the
            case may be, shall prevail.

17.11       Any notice or delivery required or permitted to be given or made by
            the Company to the Subscriber or vice versa shall be in writing and
            shall be made or given by delivering the same manually or by mailing

                                "Purchasers").

ISSUE:                          CDN$17 - $19.5 million (the "Issue Amount")
                                consisting of 17,000 to 19,500 Units. Each Unit
                                will consist of 20 preferred shares (the
                                "Preferred Shares") convertible into common
                                shares of the Company and 588 share purchase
                                warrants (the "Warrants"); provided that the
                                issuance of the Units is conditional upon the
                                Company obtaining TSX and shareholder approval.

PRICE PER UNIT:                 CDN$1,000.01 per Unit (including the
                                consideration for the Warrants of $0.01 per
                                Unit).

OPTIONAL CONVERSION:            Each Preferred Share will be
                                convertible at the option of the holder into the
                                number of Common Shares of the Company that is
                                determined by dividing the issue price of CDN$50
                                per Preferred Share by CDN $0.85 (with each
                                Preferred Share being convertible into
                                approximately 58.82 common shares).

MANDATORY CONVERSION:           The Company may require the Purchasers to
                                convert the Preferred Shares to Common Shares if
                                (i) at any time after twelve (12) months
                                following the closing date, the closing price of
                                the Common Shares has been greater than 250% of
                                the fixed Conversion Price of CDN $0.85 for at
                                least twenty (20) consecutive trading days, or
                                (ii) at any time upon the Company's sale of its
                                Common Shares in a firm commitment public
                                underwritten offering in which (a) the offering
                                price of the Common Shares is greater than 200%
                                of the fixed Conversion Price of CDN $0.85, (b)
                                the aggregate gross proceeds exceed CDN $40
                                million, and (c) the underlying Common Shares
                                are freely tradable.

CONVERSION DATE:                The date on which a Purchaser delivers to
                                the Company a notice of conversion together with
                                the certificates representing the Preferred
                                Shares being converted duly endorsed for
                                transfer.

DIVIDENDS:                      Fixed cumulative dividends at the rate of 7% per
                                annum, payable semi-annually or upon conversion
                                or redemption.

WARRANTS:                       The number of whole Warrants issued for each
                                Unit subscribed for will be 588. Each whole
                                Warrant will entitle the holder to purchase one
                                Common Share of the Company at the exercise
                                price of CDN $0.85. The Warrants shall be
                                exercisable for a period of five years from the
                                date of issuance at any time at the election of
                                the holders. During the first twelve months
                                following closing, the Warrants will be
                                exercisable for cash. Thereafter until
                                expiration, the Warrants will be exercisable for
                                cash or by cashless exercise (reducing the
                                number of shares to be issued by the Company).
                                The Company may redeem the Warrants for $0.10
                                per Warrant upon twenty days notice, provided
                                that (i) the Common Shares closes above 300% of
                                the exercise price for a period of twenty
                                consecutive trading days, and (ii) the Common
                                Shares underlying the Warrants are freely
                                tradable. Any Warrants which are the subject of
                                a redemption notice may be exercised within the
                                20 day notice period.

COMPANY'S RIGHT OF              The Company will also have the right, but not
REDEMPTION:                     the obligation, to redeem the Preferred Shares
                                at any time after 3 years following the closing
                                date at the original issue price plus a premium
                                of 20% of the original issue price. A holder
                                will have 20 days after receipt of notice of
                                redemption within which to convert the Preferred
                                Shares to Common Shares.

LIQUIDATION PREFERENCE:         The liquidation preference per share shall equal

                                issuance of stock or debt financing for
                                situations involving strategic partnerships,
                                acquisition candidates and public underwritten

                                like. The Company will not issue any securities

                                withholding or deduction in connection with the
                                Preferred Shares, Warrants, or the conversion or
                                exercise thereof, in respect of any present or
                                future tax, levy, duty, impost, assessment or
                                other governmental charge as required by law.

                                reasonably practicable, having regard to the
                                regulatory requirements for the calling of
                                shareholders' meetings. The Company's management
                                will recommend that the shareholders approve the

                                For greater certainty, the parties intend that
                                upon receipt of shareholder approval, the

                                      subscription funds to the Company; and

                                (d)   the Purchasers will receive interest on
                                      the subscription funds at a rate of 12%
                                      per annum, less applicable withholding tax
                                      and the consideration for the Warrants of

                                  SCHEDULE "B"

                           CERTIFICATE OF U.S. PERSON

             THIS FORM MUST BE COMPLETED BY UNITED STATES INVESTORS.

A "United States investor" is any person in the United States at the time such
person's buy order is made or any "U.S. person" as defined in Regulation S under
the United States Securities Act of 1933, as amended. This will include: (a) any
natural person resident in the United States; (b) any partnership or corporation
organized or incorporated under the laws of the United States; (c) any trust of
which any trustee is a U.S. person; (d) any partnership or corporation organized
outside the United States by a U.S. person principally for the purpose of
investing in securities not registered under the U.S. Securities Act of 1933,
unless it is organized or incorporated, and owned, by U.S. Accredited Investors
who are not natural persons, estates or trusts; and (e) any estate of which any
executor or administrator is a U.S. person.

The capitalized terms used herein and not defined herein shall have the meanings
ascribed to them in the Subscription Agreement to which this Schedule "B" is
attached.

The Subscriber covenants, represents and warrants to the Issuer that:

      (a)   it understands that the Securities have not been registered under
            the U.S. Securities Act or any state securities laws and that the
            sale contemplated hereby is being made in reliance on the exemption
            from such registration requirement provided by Rule 506 of
            Regulation D;

      (b)   it acknowledges that it has not purchased the Securities as a result
            of any form of general solicitation or general advertising,
            including advertisements, articles, notices or other communications
            published in any newspaper, magazine or similar media or broadcast
            over radio, or television, or any seminar or meeting whose attendees
            have been invited by general solicitation or general advertising;

      (c)   it understands and agrees that there may be material tax
            consequences to the Subscriber of an acquisition, disposition or
            exercise of any of the Securities. The Issuer gives no opinion and
            makes no representation with respect to the tax consequences to the
            Subscriber under United States, state, local or foreign tax law of
            the undersigned's acquisition or disposition of such securities. In
            particular, no determination has been made whether the Issuer will
            be a "passive foreign investment company" ("PFIC") within the
            meaning of Section 1291 of the United States Internal Revenue Code;

      (d)   it understands and agrees that the financial statements of the
            Issuer have been prepared in accordance with Canadian generally
            accepted accounting principles, which differ in some respects from
            United States generally accepted accounting principles, and thus may
            not be comparable to financial statements of United States
            companies;

      (e)   if an individual, it is a resident of the state or other
            jurisdiction listed in its address on the signature page of the
            Subscription Agreement, or if the Subscriber is not an individual,
            the office of the Subscriber at which the Subscriber received and
            accepted the offer to purchase the Issuer's Units is the address
            listed on the signature page of the Subscription Agreement;

      (f)   it, alone or with the assistance of its professional advisors, has
            such knowledge and experience in financial and business matters as
            to be capable of evaluating the merits and risks of an investment in
            the Securities and is able, without impairing its financial
            condition, to hold such securities for an indefinite period of time
            and to bear the economic risk of loss of, and withstand the complete
            loss of, its entire investment;

                                       B-2

            receive answers concerning the terms and conditions of the offering
            and it has had access to such information concerning the Issuer as
            it has considered necessary or appropriate in connection with its
            investment decision to acquire the Securities;

      (h)   it is acquiring the Securities for its own account and not on behalf
            of any other person for investment purposes only and not with a view
            to any resale, distribution or other disposition of the Securities
            in violation of the United States federal and state securities laws;

      (i)   if it decides to offer, sell or otherwise transfer any of the
            Securities, it will not offer, sell or otherwise transfer any of
            such Securities directly or indirectly, unless

            (i)   the transfer is to the Issuer;

            (ii)  the transfer is made outside the United States in a
                  transaction meeting the requirements of Rule 904 of Regulation
                  S and in compliance with applicable local laws and
                  regulations;

            (iii) the transfer is made in compliance with an exemption from the
                  registration requirements under the U.S. Securities Act
                  provided by Rule 144 or Rule 144A thereunder, if available; or

            (iv)  the Securities are transferred in a transaction that does not
                  require registration under the U.S. Securities Act or any
                  applicable state laws and regulations governing the offer and
                  sale of securities, and it has prior to such sale furnished to
                  the Issuer an opinion of counsel in form and substance
                  satisfactory to the Issuer;

                    FORM OF DECLARATION FOR REMOVAL OF LEGEND

TO:   Registrar and transfer agent for the shares of OFFSHORE SYSTEMS
      INTERNATIONAL LTD. (the "Issuer").

The undersigned (A) acknowledges that the sale of the securities of the Issuer
to which this declaration relates is being made in reliance on Rule 904 of
Regulation S under the United States Securities Act of 1933, as amended (the
"U.S. Securities Act"), and (B) certifies that (1) the undersigned is not an
"affiliate" of the Issuer (as that term is defined in Rule 405 under the U.S.
Securities Act); (2) the offer of such securities was not made to a person in
the United States and either (a) at the time the buy order was originated, the
buyer was outside the United States, or the seller and any person acting on its
behalf reasonably believed that the buyer was outside the United States, or (b)
the transaction was executed on or through the facilities of the TSX and neither
the seller nor any person acting on its behalf knows that the transaction has
been prearranged with a buyer in the United States; (3) neither the seller nor
any affiliate of the seller nor any person acting on their behalf has engaged or
will engage in any directed selling efforts in the United States in connection
with the offer and sale of such securities; (4) the sale is bona fide and not
for the purpose of "washing off" the resale restrictions imposed because the
securities are "restricted securities" (as that term is defined in Rule
144(a)(3) under the U. S. Securities Act); (5) the seller does not intend to
replace such securities with fungible unrestricted securities; and (6) the
contemplated sale is not a transaction, or part of a series of transactions,
which, although in technical compliance with Regulation S, is part of a plan or
scheme to evade the registration provisions of the U.S. Securities Act. Terms
used herein have the meanings given to them by Regulation S under the U.S.
Securities Act.

YOU ARE BUYING EXEMPT MARKET SECURITIES
They are called exempt market securities because two parts of securities law do
not apply to them. If an issuer wants to sell exempt market securities to you:

-     the issuer does not have to give you a prospectus (a document that
      describes the investment in detail and gives you some legal protections),
      and

-     the securities do not have to be sold by an investment dealer registered
      with a securities regulatory authority.

There are restrictions on your ability to resell exempt market securities.
Exempt market securities are more risky than other securities.

YOU MAY NOT RECEIVE ANY WRITTEN INFORMATION ABOUT THE ISSUER OR ITS BUSINESS
If you have any questions about the issuer or its business, ask for written
clarification before you purchase the securities. You should consult your own
professional advisers before investing in the securities.

YOU WILL NOT RECEIVE ADVICE [Instruction: Delete if sold by registrant]
Unless you consult your own professional advisers, you will not get professional
advice about whether the investment is suitable for you.

For more information on the exempt market, refer to the Saskatchewan Financial
Services Commission's website at http://www.sfsc.gov.sk.ca.

[Instruction: The purchaser must sign 2 copies of this form. The purchaser and
the issuer must each receive a signed copy.]<PAGE>

Further to our recent correspondence and discussions, this letter constitutes a
binding offer by Offshore Systems International Ltd. ("OSIL") to purchase all of
the issued and outstanding shares of Mapcon Mapping Consultants Inc. (the

OSIL's offer set out in this letter is conditional only upon the preparation of
a mutually satisfactory Definitive Agreement and final approval of OSIL's board
of directors.

BACKGROUND

This offer is made by OSIL based upon the following understandings:

      (a)   Mapcon is a privately owned Utah corporation;

      (b)   Phillip Floor and Steven Floor (the "Shareholders") are and will on
            closing be the registered and beneficial owners of 100% of the
            issued and outstanding Mapcon Shares, each as to 50%. No other party
            has any right or option by way of exercise, conversion or otherwise,
            to acquire any of the Mapcon Shares or any un-issued securities in
            the capital of Mapcon;

      (c)   There will be no material adverse change in the business or affairs
            of Mapcon between the projected financial statements for the period
            ended December 31, 2004 as set out in the e-mail dated November 05,
            2004 2:06 PM from Gary Manzer to Steve Floor (doc@mapcomapping.com)
            and Phillip Floor (phil@mapcomapping.com), attached hereto for
            reference, and closing.

INTENT TO PURCHASE SHARES

OSIL offers to purchase the Mapcon Shares. OSIL reserves the right to purchase
the Mapcon Shares directly or through an affiliated or subsidiary entity or a
combination thereof. The obligation of

                                                                     Page 1 of 5

<PAGE>

payment remains with OSIL. The purchase of the Mapcon Shares will be subject to
the following terms and conditions:

1.    PURCHASE PRICE

      The total purchase price (the "PURCHASE PRICE") will be one million United
      States dollars (USD$1,000,000) including the shares described in section
      2(b), subject to adjustment in accordance with section 3. All dollar
      amounts referred to in this letter will mean US dollars unless otherwise
      stipulated.

2.    TERMS OF PAYMENT AND ALLOCATION OF PURCHASE PRICE

      The Purchase Price will be paid and satisfied as follows:

      (a)   By payment of USD$950,000 to the Shareholders in cash as follows:

            (i)   USD$530,000 to be paid by certified cheque, bank draft or wire
                  transfer on closing, in accordance with the Definitive
                  Agreement; and

            (ii)  USD$300,000 to be paid to the Shareholders, subject to
                  adjustment and escrow in accordance with sections 3 and 4(b);
                  and

            (iii) USD$120,000 to be paid to the Shareholders subject to
                  adjustment and escrow in accordance with sections 3c and 4(b);

            capital of OSIL with an aggregate value of USD$50,000 (the "OSIL
            Shares"). The number of OSIL shares to be issued will be determined
            by dividing USD$50,000 by the average 30 day trading price of OSIL's
            common shares prior to the date on which the Definitive Agreement is
            signed. The trading price for OSIL's shares is quoted in Canadian
            dollars. The average exchange rate (quoted by the Bank of Canada)
            over the same 30 day period will be used for converting Canadian
            dollars to US dollars.

3.    HOLDBACK AND ADJUSTMENTS

      (a)   A total of $300,000 of the cash portion of the Purchase Price
            payable on closing will be held in escrow for a period of ninety
            (90) days following closing, pending the making of final working
            capital adjustments, based on Background item (c), and financial
            statements prepared at the closing date that are prepared on a
            consistent basis with those referenced in Background item (c). The
            parties will act with reasonable diligence and in good faith to
            finalize such adjustments within a reasonable time period. Any net
            adjustments in favour of OSIL will be deducted from the holdback,
            and the balance of the holdback remitted to the Shareholders within
            ninety (90) days. Any net adjustments in favour of the Shareholders
            will be paid to the Shareholders promptly upon completion of the
            adjustment calculations, and the holdback paid to the Shareholders .
            In no event shall such working capital adjustments reduce the
            purchase price without the consent of the shareholders.

                                                                     Page 2 of 5

            Orders received from the USFS will be reviewed every three months at
            the end of May, August, November, and February and a pro rata
            portion of the held back amount will be released by the end of the
            following month.

            OSIL are listed for trading on the TSX in Canada and are also quoted
            for trading on the "OTCBB" in the United States. The OSIL Shares

      negotiations or discussions with any party other than OSIL and its
      representatives respecting a possible sale of the Mapcon Shares, a sale of
      the assets of Mapcon, or any other merger or business combination
      respecting Mapcon unless the parties fail to conclude a definitive
      agreement by March 31, 2005.

10.   PREPARATION OF AGREEMENT -

      The parties will use their reasonable best efforts to enter into a formal
      agreement (the "Definitive Agreement") encompassing the subject matter
      hereof and other provisions which are typical and customary for
      transactions of like nature within 30 days, with an anticipated closing
      date of March 14, 2005.

11.   EXPENSES

      Each of OSIL and Mapcon shall be responsible for its own legal, consulting
      and other costs and expenses incurred by it with respect to this letter of
      intent and the formal agreements contemplated by this letter of intent. In
      the event that the transactions contemplated by this letter of intent do
      not result in the execution of a formal purchase and sale agreement with
      respect to the Mapcon Shares, neither party shall have any claim against
      the other (except pursuant to section 8 or section 9 of this letter of
      intent or pursuant to the NDA) as a result of such failure to reach a
      formal agreement.

      The closing audited financial statements of Mapcon shall be prepared in
      accordance with U.S. GAAP by a mutually agreed audit firm and the cost of
      such statements shall be paid equally by OSIL and Mapcon. The purpose of
      the GAAP Audit is to assign values to any holdbacks or adjustments. The
      audit fee itself is to be treated as one of the Section 3 adjustments.

12.   NEWS RELEASES

      The parties acknowledge that OSIL, as a publicly trading corporation, has
      a legal obligation to issue news releases respecting any material changes
      in its affairs and to file material change reports with securities
      regulatory authorities in Canada and the U.S. As such, OSIL may have an
      obligation to issue a news release concerning the execution of this letter
      of intent and will be required to do so with respect to any formal
      agreement in furtherance of the transactions contemplated by this letter
      of intent. OSIL agrees to deliver to a representative appointed by Mapcon
      a draft of any such news releases for review and comment by that
      representative. That representative shall have 24 hours within which to
      provide any comments concerning the draft news release. OSIL agrees to
      take the comments of such representative into account and to act
      reasonably in finalizing any news releases that it issues concerning its
      dealings with Mapcon.

                                                                     Page 4 of 5
