               Sales of at least U.S. $600,000 during each of such four
               additional months and, in addition, during each of which
               additional four months a similar Profit Margin of at least twenty
               percent (20%) was maintained by either the Purchaser, its
               subsidiary or its Trading Subsidiary, as the case may be, in
               respect of such Gross Sales (the "Second Performance Share
               Issuance"); and

        (c)    subject to the prior obligation and completion of each of the
               Initial Performance Share Issuance and the Second Performance
               Share Issuance under the conditions and during the initial five
               month and additional four month periods as contemplated in
               paragraphs "3.4(a)" and "3.4(b)" hereinabove, the final 250,000
               of the Performance Shares shall be issuable to the order and
               direction of the Vendors on or before 60 calendar days from the
               last day of any calendar month which is determined to then be the
               third such further consecutive calendar month during a period in
               which either the Purchaser, its subsidiary or its Trading
               Subsidiary, as the case may be, maintained Gross Sales of at
               least U.S. $800,000 during each of such three additional months
               and, in addition, during each of which additional three months a
               similar Profit Margin of at least twenty percent (20%) was
               maintained by either the Purchaser, its subsidiary or its Trading
               Subsidiary, as the case may be, in respect of such Gross Sales.

3.5 CALCULATION AND COLLECTION OF GROSS SALES. It is hereby acknowledged and
agreed that the Royalty shall be accounted for monthly, and within 30 calendar
days after the end of each such month, and that the first month shall commence
on the first business day of the month following the month of the Effective Date
hereof. The Royalty shall be calculated on all amounts invoiced, or deemed
invoiced, in a month. Within 30 calendar days (or such extended time as the
Parties may permit) of the end of each month the Purchaser, its subsidiary or
its Trading Subsidiary, as the case may be, shall be required to render a
monthly accounting statement with explanatory notes, shall make any adjustments
thereto and shall calculate any Royalty due from such adjustment upon
presentation of such accounting or give notice of any deduction to be carried to
apply to Gross Sales for the next month. The calculation of Gross Sales shall be
carried out in accordance with generally accepted United States accounting
principles applied on a consistent basis. In this regard the Vendors may contest
any accounting within 15 calendar days of presentation of such report. However,
an accounting may be challenged at any time if it comes to the attention of the
Vendors that the Purchaser has failed to clearly disclose any material fact or
Gross Sale therein. It will be the responsibility of the Purchaser, its
subsidiary or its Trading Subsidiary, as the case may be, to collect the amounts
of Gross Sales and all risk of such shall be that of the Purchaser.
Notwithstanding that the Purchaser shall not have invoiced a customer, it shall
be deemed to have invoiced for all Product on the tenth calendar day after
delivery of the same unless special circumstances, with prior approval in
writing by the Vendors, pertain. However, the Purchaser may deduct from Gross
Sales upon which a Royalty is calculated the uncollected receivables from
preceding months which the Purchaser has made bona fide and reasonable best
efforts to collect, but the cost of collection shall not be deducted from Gross
Sales for the purpose of any Royalty calculation. All calculated Gross Sales
figures shall be made in U.S. dollars without any reduction or deduction of any
nature or kind whatsoever, except as set forth in this Agreement. In this regard
the Purchaser shall not exercise any set-off, deduction or any other reduction
to the Gross Sales whether for claims of damages, costs or any other amount
excepting only the uncollected receivables as set forth hereinabove. In the
event that there is any dispute about the calculation or deductibility of
uncollected receivables, such shall be determined by arbitration in accordance
with Article "17" hereinbelow.

                                    ARTICLE 4

                   INTERIM SECURED LOAN AND SECURITY THEREFORE

4.1 INTERIM SECURED LOAN FROM THE PURCHASER TO THE VENDORS. In conjunction with
and as a condition to the entering into of this Agreement by the Parties hereto,
and prior to the Closing (as hereinafter determined) the Purchaser has agreed to
hereby advance by way of a loan or loans to the Vendors (collectively,

                                      -7-

the "Loan") the aggregate principal sum of up to U.S. $250,000 (collectively,

Principal Sum and Interest will be secured, contemporaneously with the
advancement of any funds under any such Loan, by way of a senior fixed and
floating charge on all of the assets of the Vendors (collectively, the
"Security"). In this regard it is hereby acknowledged and agreed that, upon the
completion of the within purchase and sale, it is intended, subject to the
Purchaser's prior receipt of appropriate accounting and legal advice, that the
Loan will simply be forgiven or become an inter-company account as the situation
may require.

concluding the transactions contemplated thereby, that:

         (a)   the Vendors will use any such Principal Sum monies which may be

               maintenance of the Business and Property interests utilizing the
               Shareholder's General Services through the Purchaser and in
               particular, however, without limitation, in the furtherance of
               generating Gross Sales for the Purchaser; and

               fulfillment of at least the following Security conditions to the
               sole and absolute satisfaction and discretion of the Purchaser:

               (i)    the execution by the Vendors of formal Loan documentation

                      United States Uniform Commercial Code registration
                      statements) as may be required by the Purchaser and its
                      counsel, acting reasonably, in order to evidence the Loan,
                      together with and all other supporting documents required
                      under any such Security documentation; and

               (iii)  the execution by the Vendors of such formal documentation
                      in form and substance satisfactory to the Purchaser and

                      the Shareholder (the "Trading Account") in that instance,
                      whereupon, should either this Agreement be terminated for
                      any reason whatsoever by either or both Parties, or should
                      the Purchaser either relinquish, abandon or transfer back
                      to the Vendors all or any portion of the Property at any
                      time after the Execution Date hereof, then all Product,
                      gemstones and funds then remaining in such Trading Account
                      shall be returned to the sole and absolute benefit and
                      direction of the Purchaser without recourse to the
                      Vendors.

                DUE DILIGENCE, NON-DISCLOSURE AND CONFIDENTIALITY

8.1 DUE DILIGENCE. Each of the Parties hereto may conduct such further due
diligence examination of the other Parties hereto as it deems appropriate. Each
Party may in a reasonable manner carry out such investigations and due diligence
as to the other Parties hereto, at all times subject to the confidentiality
provisions hereinbelow, as each Party deems advisable. In that regard the
Parties agree that each shall have full and complete access to the other
Parties' books, records, financial statements and other documents, articles of
incorporation, by-laws, minutes of Board of Directors' meetings and its
committees, investment agreements, material contracts and as well such other
documents and materials as the Parties hereto, or their respective counsel, may
deem reasonable and necessary to conduct an adequate due diligence investigation
of each Party, its respective operations and financial condition prior to the

8.2 NON-DISCLOSURE. Subject to the provisions of hereinbelow, the Parties
hereto, for themselves, their officers, directors, shareholders, consultants,
employees and agents, agree that they each will not disseminate or disclose, or
knowingly allow, permit or cause others to disseminate or disclose to third
parties who are not subject to express or implied covenants of confidentiality,
without the other Parties' express written consent, either: (i) the fact or
existence of this Agreement or discussions and/or negotiations between them
involving, inter alia, possible business transactions; (ii) the possible
substance or content of those discussions; (iii) the possible terms and
conditions of any proposed transaction; (iv) any statements or representations
(whether verbal or written) made by either Party in the course of or in
connection with those discussions; or (v) any written material generated by or
on behalf of any Party and such contacts, other than such disclosure as may be
required under applicable securities legislation or regulations, pursuant to any
order of a Court or on a "need to know" basis to each of the Parties' respective
professional advisors. Any document or written material

                                      -14-
   15

generated by either Party hereto in the course of, or in connection with, the
due diligence investigations conducted pursuant to this Agreement shall be
marked "Confidential" and shall be treated by each Party as a trade secret of
the other Parties. Upon termination of this Agreement prior to Closing all
copies of any and all documents obtained by any Party from any other Party
herein, whether or not marked "Confidential", shall be returned to the other
Parties forthwith. Notwithstanding the provisions of this Article, the Parties
hereto agree to make such public announcements of this Agreement promptly upon
its execution in accordance with the requirements of applicable securities
legislation and regulations.

8.3 CONFIDENTIAL INFORMATION. Each Party hereto acknowledges that any and all
information which a Party may obtain from, or have disclosed to it, about the
other Parties constitutes valuable trade secrets and proprietary confidential
information of the other Parties (collectively, the "Confidential Information").
No such Confidential Information shall be published by any Party without the
prior written consent of the other Parties hereto, however, such consent in
respect of the reporting of factual data shall not be unreasonably withheld, and
shall not be withheld in respect of information required to be publicly
disclosed pursuant to applicable securities or corporation laws. Furthermore,
each Party hereto undertakes not to disclose the Confidential Information to any
third party without the prior written approval of the other Parties and to
ensure that any third party to which the Confidential Information is disclosed
shall execute an agreement and undertaking on the same terms as contained
herein. The Parties hereto acknowledge that the Confidential Information is
important to the respective businesses of each of the Parties and that, in the
event of disclosure of the Confidential Information, except as authorized
hereunder, the damage to each of the Parties hereto, or to either of them, may
be irreparable. For the purposes of the foregoing sections the Parties recognize
and hereby agree that a breach by any of the Parties of any of the covenants
therein contained would result in irreparable harm and significant damage to
each of the other Parties that would not be adequately compensated for by
monetary award. Accordingly, the Parties agree that in the event of any such
breach, in addition to being entitled as a matter of right to apply to a Court
of competent equitable jurisdiction for relief by way of restraining order,
injunction, decree or otherwise as may be appropriate to ensure compliance with
the provisions hereof, any such Party will also be liable to the other Parties,
as liquidated damages, for an amount equal to the amount received and earned by
such Party as a result of and with respect to any such breach. The Parties also
acknowledge and agree that if any of the aforesaid restrictions, activities,
obligations or periods are considered by a court of competent jurisdiction as
being unreasonable, the Parties agree that said court shall have authority to
limit such restrictions, activities or periods as the court deems proper in the
circumstances. In addition, the Parties further acknowledge and agree that all
restrictions or obligations in this Agreement are necessary and fundamental to
the protection of the respective businesses of each of the Parties and are
reasonable and valid, and all defenses to the strict enforcement thereof by
either of the Parties are hereby waived by the other Parties.

                                    ARTICLE 9

                                   ARBITRATION

to the provisions hereof that any Party intending to refer any matter to
arbitration shall have given not less than 10 calendar days' prior written

of the matter in dispute. On the expiration of such 10 calendar days the Party
who gave such notice may proceed to refer the dispute to arbitration as provided
in section "9.2" hereinbelow.

arbitrator, and shall notify the other Parties of such appointment, and the
other Parties shall, within 10 calendar days after receiving such notice,
appoint an arbitrator, and the two arbitrators so named, before proceeding to
act, shall, within 10 calendar days of the appointment of the last appointed
arbitrator, unanimously agree on the appointment of a third arbitrator, to act
with them and be chairman of the arbitration herein provided for. If the other
Parties shall fail to appoint an arbitrator within 10 calendar days after
receiving notice of the appointment of the first arbitrator, or if the two
arbitrators appointed by the Parties shall be unable to agree on the appointment
of the chairman, the chairman shall be appointed under the provisions of the
Commercial Arbitration Act (British Columbia) (the "Act"). Except as
specifically otherwise provided in this section, the arbitration herein provided
for shall be conducted in accordance with such Act. The chairman, or in the case
where only one arbitrator is appointed, the single arbitrator, shall fix a time

Parties, and he shall preside over the arbitration and determine all questions
of procedure not provided for under such Arbitration Act or this section. After
hearing any evidence and representations that the Parties may submit, the single
arbitrator, or the arbitrators, as the case may be, shall make an award and
reduce the same to writing, and deliver one copy thereof to each of the Parties.
The expense of the arbitration shall be paid as specified in the award. The
Parties hereto agree that the award of a majority of the arbitrators, or in the
case of a single arbitrator, of such arbitrator, shall be final and binding upon
each of them.

designating such default, and within 10 calendar days after its receipt of such
notice, the Defaulting Party shall either:
