as to the fairness of the investment, or any recommendation or endorsement of
the Shares or any other securities of the Company; and

(e) the Company may not because of the current policies of British Columbia

the Option or any interest in, or right to, the Option.

6.02 A trade by the Director of an Optioned Share is deemed to be a distribution
under the B.C. Act and the Securities Rules (B.C.) unless:

(a) the Company is at the time of the trade a reporting issuer not in default of
any requirement of the B.C. Act and the Securities Rules (B. C.); and

(f) no extraordinary commission or consideration is to be paid in respect of the
trade.

ARTICLE 7 ADJUSTMENT OF NUMBER OF OPTIONED SHARES

7.01 The number of Optioned Shares deliverable upon the exercise of the Option
will be adjusted as follows:

(a) if there is any subdivision or subdivisions of the Shares while the Option
is in effect into a greater number of Shares, the Company will deliver at the
time of purchase of Optioned Shares, in addition to the number of Optioned
Shares in respect of which the right to purchase is being exercised, such
additional number of Optioned Shares as result from such subdivision or
subdivisions without the Director making any additional payment or giving any
other consideration;

(b) if there is any consolidation or consolidations of the Shares while the
Option is in effect into a lesser number of Shares, the Company will deliver and
the Director will accept, at the time of purchase of Optioned Shares, instead of
the number of Optioned Shares in respect of which the right to purchase is being
exercised, the lesser number of Optioned Shares as a result from such
consolidation or consolidations;

<PAGE>

                                       61


(c) if there is any change of the Shares of the Company while the Option is in
effect, the Company will deliver at the time of purchase of Optioned Shares the
number of Optioned Shares of the appropriate class resulting from the such
change as the Director would have been entitled to receive in respect of the
number of Optioned Shares so purchased had the right to purchase been exercised
before such change;

(d) if there is any capital reorganization, reclassification or change of
outstanding equity shares, other than a change in the par value, of the Company
or if there is any consolidation, merger or amalgamation of the Company with or
into any other company or any sale of the property of the Company as or
substantially as an entirety at any time while the Option is in effect, the
Director may purchase and receive, instead of the Optioned Shares purchasable
and receivable upon the exercise of the Option, the kind and amount of Shares
and other securities and property receivable upon such capital reorganization,
reclassification, change, consolidation, merger, amalgamation or sale which the
holder of a number of Shares equal to the number of Optioned Shares purchasable
and receivable upon the exercise of the Option would have received as a result
of such event.

The subdivision or consolidation of Shares at any time outstanding into a
greater or lesser number of Shares, whether with or without par value, will not
be deemed to be a capital reorganization or a reclassification of the capital of
the Company for the purposes of this paragraph (d).

7.02 The adjustments provided for in section 7.01 are cumulative.

7.03 The Company will not be required to issue fractional Shares in satisfaction
of its obligations and any fractional interest in a Share that would, except for
the provisions of this section, be deliverable upon the exercise of the Option
will be cancelled and not be deliverable by the Company.

7.04 If any questions at any time arise with respect to the exercise price or
number of Optioned Shares deliverable upon exercise of the Option, such
questions will be conclusively determined by the Company's auditors, or, if they
decline to so act, any other firm of chartered accountants in Vancouver, British
Columbia that the Company may designate and who will have access to all
appropriate records and such determination will be binding upon the Company and
the Director.

7.05 The Director will have no rights whatsoever as a shareholder in respect of
any of the Optioned Shares, including any right to receive dividends or other
distributions, other than in respect of Optioned Shares in respect of which the
Director has exercised its Option and which the Director has taken up and paid
for.

7.06 The Company represents and warrants to, and covenants with the Director
that:

(a) the Company will use its best efforts to proceed to have its Shares
registered under the Securities Exchange Act of 1934 and if the policies of
applicable securities administrators change to become a reporting issuer in
British Columbia; and

<PAGE>

                                       62

(b) the Company will reserve in its treasury sufficient Shares to permit the
issuance and allotment of the Optioned Shares to the Director if the Option or
any part thereof is exercised.
