<PAGE>



         THE SECURITIES OFFERED AND PURCHASED HEREBY HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "1933 ACT") AND THE
         RULES AND REGULATIONS PROMULGATED THEREUNDER, AND MAY NOT BE OFFERED OR
         SOLD DIRECTLY OR INDIRECTLY WITHIN THE UNITED STATES OR TO OR FOR THE
         ACCOUNT OR BENEFIT OF U.S. PERSONS (AS DEFINED IN REGULATION S) EXCEPT
         PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AS TO SUCH SECURITIES
         UNDER OR AN EXEMPTION FROM, THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT. THIS SUBSCRIPTION AGREEMENT SHALL NOT CONSTITUTE AN
         OFFER TO SELL NOR A SOLICITATION OF AN OFFER TO BUY THE SECURITIES
         OFFERED HEREBY IN THE UNITED STATES OR ANY OTHER JURISDICTION IN WHICH
         SUCH AN OFFER OR SOLICITATION WOULD BE UNLAWFUL.

The Company, in its sole absolute discretion, may reduce the undersigned's
subscription to any number of Units that in the aggregate does not exceed the
number of Units hereby applied for without any prior notice to or further
consent by the undersigned. The undersigned hereby irrevocably constitutes and
appoints the Company and each officer of the Company, each of the foregoing
acting singly, in each case with full power of substitution, the true lawful
agent and attorney-in-fact of the undersigned, with full power and authority in
the undersigned's name, place and stead, to amend this Subscription Agreement
including in each case the undersigned's signature page thereto, to effect any
of the foregoing provisions of this Paragraph;

The undersigned will not sell or otherwise transfer the Shares without
registration under the Securities Act or pursuant to an applicable state
securities laws or exemption therefrom. The Shares forming part of the Units,
the Warrants and the Warrant Shares have not been registered under the
Securities Act or under the securities laws of any states. The undersigned
represents that the undersigned is purchasing the Units for the undersigned's
own account, for investment and not with a view to resale or distribution except
in compliance with the Act. The undersigned has not offered or sold any portion
of the Units being acquired nor does the undersigned have any present intention
of dividing such Units with others or of selling, distributing or otherwise
disposing of any portion of such Units either currently or after the passage of
a fixed or determinable period of time or upon the occurrence or non-occurrence
of any predetermined event or circumstance in violation of the Securities Act.

No United States or Canadian federal, or provincial agency (as the case may be)
has made any finding or determination as to the fairness of the terms of this
Subscription Agreement;

The Offering made hereunder is intended to be exempt from the registration under
the Securities Act by virtue of Section 4(2) of the 1933 Act and the provisions
of Regulation S in the case of "non- U.S. persons" (as defined in Regulation S
under the Securities Act), thereunder, which is in part dependent upon the
truth, completeness and accuracy of the statements made by the undersigned
herein;



<PAGE>



The representations, warranties and agreements of the undersigned contained
herein and in any other writing delivered in connection with the transaction
contemplated hereby shall be true and correct in all respects on and as of the
date of the sale of the Units as if made on and as of such date and shall
survive the execution and delivery of this Subscription Agreement and the
purchase of the Units;

Insofar as indemnification for liabilities under the 1933 Act may be permitted
to directors, officers or controlling persons of the Company, the Company has
been informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in such Act and is
therefore unenforceable to such extent;

IN MAKING AN INVESTMENT DECISION PURCHASERS MUST RELY ON THEIR OWN EXAMINATION
OF THE COMPANY AND THE TERMS OF THE OFFERING, INCLUDING THE MERITS AND RISKS
INVOLVED, THE UNITS HAVE NOT BEEN RECOMMENDED BY ANY FEDERAL OF STATE SECURITIES
COMMISSION OR REGULATORY AUTHORITY. FURTHERMORE, THE FOREGOING AUTHORITIES HAVE
NOT CONFIRMED THE ACCURACY OR DETERMINED THE ADEQUACY OF THIS DOCUMENT. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE;

THE SHARES FORMING PART OF THE UNITS, THE WARRANTS AND THE WARRANT SHARES MAY
NOT BE TRANSFERRED, RESOLD OR OTHERWISE DISPOSED OF EXCEPT AS PERMITTED UNDER
THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO
REGISTRATION OR EXEMPTION THEREFROM. PURCHASERS SHOULD BE MADE AWARE THAT THEY
WILL BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT.

In addition to the undersigned's representations, warranties and understandings
set forth elsewhere herein, if the undersigned is a non "U.S. person" as defined
in Regulation S as promulgated pursuant to the Securities Act, the undersigned
further represents, warrants and covenants that:

1.   the undersigned is not a "U.S. person" as that term is defined in
     Rule 902(o) of Regulation S;

2.   the undersigned is not, and on the Closing Date will not be, an affiliate
     of the Company;

3.   at the execution of this Subscription Agreement, the undersigned was
     outside the United States and no offer to purchase the Units was made in
     the United States;

     made in compliance with any applicable securities laws of any applicable
     jurisdiction and, particularly, in accordance with Rule 903 and 904, as
     applicable, or Regulation S or pursuant to registration of the securities
     offered hereunder (the "Securities") under the Securities Act or pursuant
     to an exemption from registration. In any case, none of the Securities have
     been and will be offered or sold by the Subscriber to, or for the account
     or benefit of a U.S. Person or within the United States until after the end
     of a one year period commencing on the Closing Date (the "Restricted
     Period"), as certified by the Company to the undersigned and, thereafter
     only pursuant to an effective registration statement as to the Securities
     or an applicable exemption therefrom;


<PAGE>



5.   the undersigned is not a distributor or dealer;

6.   the transactions contemplated hereby (a) have not been and will not be
     pre-arranged by the undersigned with a purchaser located in the United
     States or a purchaser which is a U.S. Person, and (b) are not and will not
     be part of a plan or scheme by the undersigned to evade the registration
     provisions of the 1933 Act;

7.   the undersigned shall take all reasonable steps to ensure compliance with
     Regulation S; and

8.   none of the undersigned, his affiliates or persons acting on their behalf
     have conducted and shall not conduct any "directed selling efforts" as that
     term is defined in Rule 902(b) of Regulation S, nor has the Subscriber, its
     affiliates or persons acting on their behalf have conducted any general
     solicitation relating to the offer and sale of any of the Securities in the
     United States or elsewhere.

The undersigned will not engage in any activity for the purposes of, or that
could reasonable be excepted to have the effect of, conditioning the market in
the United States for any of the Securities;

Neither the undersigned nor any of his affiliates will directly or indirectly
maintain any short position, purchase or sell put or call options or otherwise
engage in any hedging activities in any of the Securities or any other
securities of the Company until after the end of the Restricted Period;

This Agreement may be rejected in whole or part by the Company in its sole and
absolute discretion;

The Company has limited financial and/or operational history;

The Company has acted as the Company's Sales Agent with respect to the Offering
of the Units;

The purchase of the Units is a speculative investment, which involves a high
degree of risk of loss by the undersigned of its entire investment;

No federal or state agency has made any finding or determination as to the
fairness of public investment, nor any recommendation or endorsement, of the
Units;

The Shares forming part of the Units, the Warrants and the Warrant Shares have
not been registered under either the Federal Securities Act of 1933 (the "Act")
or applicable state securities laws (the "States' Acts") and, therefore, cannot
be resold unless and the availability of an exemption from such registration is
determined to the reasonable satisfaction to be available by legal counsel for
the Company;

My offer to subscribe for Units in the Company as herein set out is
unconditional, irrevocable and non-transferable and has not been induced by any
warranties or representations with regard to the present or future value of the
Company's Shares;

The Units to be issued to me upon acceptance of this subscription will be issued
as an exempt trade, and no securities filings or clearances or reviews have been
or are being made in connection with such trade;



<PAGE>


I hereby agree that the funds advanced by me hereunder will immediately be used
by the Company for general corporate purposes and will be characterized as a
non-interest bearing, non-callable loan by me to the Company until acceptance or
rejection of this subscription;

I confirm that neither the Company nor any director of the Company has made to
me or makes herein any representations about the present or future value of the
Company's Shares, and making this offer, I have relied solely on the
representations directly set out herein;

I confirm that it will be my responsibility to comply with the reporting
obligations, if any, that are required under the Act as result of the purchase
of the Securities that are the subject of the within Offer including the
reporting requirements resulting from the following:

(a)  Rule 16 of the Act which provides reporting requirements for persons who
     beneficially own more than 10% of any class of security of an issuer taking
     into account that person's right to acquire equity securities through the
     exercise of warrants; and

(b)  Rule 13D or 13G which provides reporting requirements for persons who
     beneficially own more than 5% of any class of security of an issuer taking
     into account that person's right to acquire further securities within 60
     days upon the exercise of warrants.

This Unit subscription constitutes the entire agreement between the undersigned
and the Company, and there are no other agreements, warranties, representations,
conditions or covenants, written or oral, express or implied, in respect of, or
which affect, the transactions herein contemplated, and this Unit subscription
supersedes and supplants any previous dealings whatsoever between the
undersigned and the Company in respect of the said transactions.

This Agreement shall be governed by and construed and enforced in accordance
with the laws of the State of Wyoming, and to the extent it involves any United
States statute, in accordance with the laws of the United States.
