          (a)  PURCHASE FOR INVESTMENT; TRANSFERABILITY.  You represent and
     warrant to the Company that the Warrants and the shares of Underlying
     Securities are being acquired for investment and not with a view to the
     distribution or resale thereof.  You agree that the Warrants and the
     Underlying Securities may not be transferred, sold, assigned or
     hypothecated, except pursuant to a registration statement that has become
     effective under the Act, setting forth the terms of such offering, the
     underwriting discount and commissions and any other pertinent data with
     respect thereto, unless you have provided the Company with an opinion of
     counsel reasonably acceptable to the Company that such registration is not
     required.  You acknowledge that holders of the Company's Common Stock
     currently are not afforded the use of Rule 144 promulgated under the Act
     and that the Company is under no obligation to take the actions necessary
     to make such Rule available to you.

          (b)  LEGEND.  Each certificate representing Underlying Securities
     shall be imprinted with a legend in substantially the following form:

          The securities represented by this certificate were issued
          upon exercise of a stock purchase warrant granted effective
          May 17, 1995, have not been registered or qualified under
          the Securities Act of 1933 or any applicable state
          securities laws, and may not be sold or transferred in the
          absence of effective registration or qualified under such
          laws or an exemption from registration or qualification
          thereunder.  The transfer of such security also is subject
          to the conditions specified in the Warrant Agreement, dated
          as of May 17, 1995, between the Corporation and certain
          subscribers, and the Corporation reserves the right to
          refuse the transfer of such security until such conditions
          have been fulfilled with respect to such transfer.  Upon
          written request, a copy of such agreement will be furnished
          by the Corporation to the holder hereof without charge.  Any
          transferee of the security represented by this certificate
          also agrees to be bound by the terms and conditions of such
          Warrant Agreement.



                                        3







          THE WARRANTS REPRESENTED BY THIS WARRANT CERTIFICATE AND ANY
          SHARES ACQUIRED UPON THE EXERCISE THEREOF ARE SUBJECT TO A
          HOLD PERIOD AND MAY NOT BE TRADED IN BRITISH COLUMBIA UNTIL
          THE EXPIRY OF THE HOLD PERIOD EXCEPT AS PERMITTED BY THE
          SECURITIES ACT (BRITISH COLUMBIA) AND REGULATIONS MADE UNDER
          THE ACT.  FOR CANADIAN RESIDENTS, THE HOLD PERIOD EXPIRES ON
          MAY 17, 1996; HOWEVER, PURSUANT TO THE POLICIES OF THE
          VANCOUVER STOCK EXCHANGE, THE WARRANTS, IF EXERCISABLE FOR A
          PERIOD OF MORE THAN ONE YEAR, REMAIN NON-TRANSFERABLE FOR
          THE BALANCE OF THE EXERCISE PERIOD.

          (c)  Unless the content otherwise requires, references in this
     Section 3 to "you" or "your" shall mean and include a Warrantholder
     or a holder of Underlying Securities, as the case may be.

4.   EXERCISE OF WARRANTS.

     Warrants may only be exercised in full by the Warrantholder by surrender 
of the Warrant, with the form of subscription at the end thereof duly 
executed by such Warrantholder, to the Company at its principal executive 
offices, accompanied by certified or bank cashier's check payable to the 
order of the Company in the full amount obtained by multiplying the number of 
Units represented by the respective Warrant or Warrants by the Purchase Price 
per Unit.

5.   DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE.

     Any exercise of the Warrants pursuant to Section 4 hereof shall be deemed
to have been effective immediately prior to the close of business on the date on
which the Warrants with the subscription form and the check for the aggregate
Purchase Price shall have been received by the Company; except that the Company
shall not be required to open its stock transfer books in order to effect an
exercise, and the effective time in such event shall be the date the stock
transfer books are reopened.  At such time, the person or persons in whose name
or names any certificate or certificates for shares of Underlying Securities
shall be issuable upon such exercise shall be deemed to have become the holder
or holders of record of the shares of Underlying Securities so purchased.  As
soon as practicable after the exercise of any Warrant, the Company, at its
expense (including the payment by it of any applicable issue taxes), will cause
to be issued in the name of, and delivered to, the purchasing Warrantholder, a
certificate or certificates for the number of fully paid and nonassessable
shares of the Underlying Securities to which such Warrantholder shall be
entitled upon such exercise, plus in lieu of any fractional share to which such
Warrantholder would otherwise be entitled, cash in an amount determined pursuant
to Subsection 7(h) hereof.  Such certificate shall contain the legend required
by Subsection 3(b) hereof.


                                        4



6.   ANTI-DILUTION PROVISIONS.

     The Warrants are subject to the following terms and conditions during the 
term thereof:

          (a)  STOCK DISTRIBUTIONS, SPLITS AND COMBINATIONS; ADJUSTMENTS.  In
     case of (i) the outstanding shares of Common Stock (or Other Securities)
     shall be subdivided into a greater number of shares, (ii) a non-cash
     dividend in Common Stock (or Other Securities) shall be paid in respect of
     Common Stock (or Other Securities), or (iii) the outstanding shares of
     Common Stock (or Other Securities) shall be combined in to a smaller number
     of shares thereof, the number of shares of Underlying Securities per Unit
     subsequent to such subdivision or combination or at the record date of such
     dividend or distribution shall simultaneously with the effectiveness of
     such subdivision or combination or immediately after the record date of
     such dividend or distribution be equal to the number of shares of Common
     Stock and Other Securities a holder would have owned and had a right to
     receive as a result of such subdivision, combination, dividend or
     distribution if such holder had actually held of record immediately prior
     to the effectiveness of such subdivision or combination or immediately
     prior to the record date of such dividend or distribution the number of
     shares of Underlying Securities purchasable per Unit immediately prior to
     the effectiveness of such subdivision or combination or the record date of
     such dividend or distribution.

          (b)  REORGANIZATIONS AND RECAPITALIZATIONS.  In case the Company shall
     be reorganized or recapitalized by reclassifying its outstanding Common
     Stock (or Other Securities) without par value to stock with par value,
     then, as a condition of such reorganization or recapitalization, as the
     case may be, immediately after the effective time of such reorganization or
     recapitalization, each Warrantholder shall thereafter have the right to
     purchase, upon the terms and conditions specified herein, the number of
     shares of Underlying Securities per Unit that a holder would have owned and
     had the right to receive as a result of such reorganization or
     recapitalization if such holder had held of record the number of shares of
     Underlying Securities per Unit immediately prior to such reorganization or
     recapitalization.  If any consolidation or merger of the Company with
     another corporation, or the sale of all or substantially all of its assets
     to another corporation, shall be effected in such a way that holders of
     Common Stock and Other Securities shall be entitled to receive stock,
     securities or assets with respect to or in exchange for Common Stock and
     Other Securities, then, as a condition of such consolidation, merger or
     sale, immediately after the effective time of such consolidation, merger or
     sale, the Warrantholders shall thereafter, subject to the last sentence of
     this Subsection, have the right to purchase and receive upon the basis and
     upon the terms and conditions specified in this Warrant Agreement, the
     number of shares of Underlying Securities per Unit that a holder would have
     owned and had a right to receive as a result of such consolidation, merger
     or sale if such holder had actually held of record immediately prior to
     such consolidation, merger or sale the number of shares of Underlying
     Securities purchasable per Unit immediately prior to such consolidation,
     merger or sale.  If the Company is merged into or consolidated with another
     corporation under circumstances where the Company is not the surviving
     corporation or where the




                                        5







     Company will be a wholly owned subsidiary of another corporation
     (except where such merger or consolidation is effected merely in order to
     recapitalize or reincorporate the Company), or if the Company sells or
     otherwise disposes of all or substantially all of its property or assets
     to another corporation, all outstanding Warrants may be canceled by the
     Board of Directors of the Company as of the effective date of any such
     merger, consolidation or sale, provided that (i) written notice of such
     cancellation is given to each holder of a Warrant not later than 30 days
     prior to such effective date and (ii) each holder of a Warrant shall
     have the right to exercise such Warrant in full during the said 30-day
     period preceding the effective date of such merger, consolidation or sale.

          (c)  EFFECT OF DISSOLUTION OR LIQUIDATION.  In case the Company shall
     dissolve or liquidate all or substantially all of its assets, all rights
     under this Warrant Agreement and the Warrants shall terminate as of the
     date upon which a certificate of dissolution or liquidation shall be filed
     with the Secretary of State of Wyoming (or, if the Company theretofore
     shall have been merged or consolidated with a corporation incorporated
     under the laws of another state, the state of incorporation on the date
     upon which action of equivalent effect shall have been taken); provided,
     however, that (i) no dissolution or liquidation shall affect the rights
     under Subsection (b) hereof of any Warrantholder and (ii) if the Company's
     Board of Directors shall propose to dissolve or liquidate the Company, each
     Warrantholder shall be given written notice of such proposal at the earlier
     of (i) the time when the Company's shareholders are first given notice of
     the proposal or (ii) the time when notice to the Company's shareholders is
     first required.

          (d)  NOTICE OF CHANGE OF UNDERLYING SECURITIES.  Whenever the number
     of shares of Underlying Securities per Unit or the kind or amount of
     securities or assets purchasable pursuant to the Warrants shall be adjusted
     pursuant to any of the provisions of this Warrant Agreement, or the number
     of shares of Underlying Securities or the kind or amount of securities or
     assets receivable upon conversion of Underlying Securities shall be
     adjusted pursuant to the terms thereof, the Company shall forthwith
     thereafter cause to be sent to each Warrantholder a notice setting forth
     such adjustment and also setting forth in detail the facts requiring such
     adjustments.
     
7.   FURTHER COVENANTS OF THE COMPANY.

          (a)  DILUTION OR IMPAIRMENTS.  The Company will not, by amendment of
     its certificate of incorporation or through any reorganization, transfer of
     assets, consolidation, merger, dissolution, issue or sale of securities, or
     any other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms of the Warrant or of this Warrant
     Agreement, but will at all times in good faith assist in the carrying out
     of all such terms and in the taking of all such action as may be necessary
     or appropriate in order to protect the rights of the Warrantholders against
     dilution or other impairment.  Without limiting the generality of the
     foregoing, the Company:





                                        6






               (i)  shall at all times reserve and keep available, solely for
          issuance and delivery upon the exercise of the Warrants, all shares of
          the Underlying Securities from time to time issuable upon the exercise
          of the Warrants and shall use its best efforts to ensure that the par
          value per share, if any, of the Underlying Securities is at all times
          equal to or less than the then effective Purchase Price per share of
          Underlying Securities; and
          
               (ii)  will take all such action as may be necessary or
          appropriate in order that the Company may validly and legally issue
          fully paid and nonassessable shares of Common Stock and Other
          Securities upon the exercise of the Warrants from time to time
          outstanding.
          
          (b)  TITLE TO STOCK.  All shares of the Underlying Securities
     delivered upon the exercise of the Warrants shall be validly issued, fully
     paid and nonassessable; each holder of a Warrant shall receive good and
     marketable title to the Underlying Securities, free and clear of all voting
     and other trust arrangements, liens, encumbrances, equities and claims
     whatsoever; and the Company shall have paid all taxes, if any, in respect
     of the issuance thereof.
     
          (c)  LISTING ON SECURITIES EXCHANGES; REGISTRATION.  If the Company at
     any time shall list any Common Stock on any national securities exchange,
     the Company will, at its expense, simultaneously list on such exchange,
     upon official notice of issuance upon the exercise of the Warrants, and
     maintain such listing of, all shares of Common Stock included in the
     Underlying Securities from time to time issuable upon the exercise of the
     Warrants or upon conversion of Underlying Securities, and the Company will
     so list on any national securities exchange, will so register, and will
     maintain such listing of, any Other Securities if and at the time that any
     securities of such class shall be listed on such national securities
     exchange by the Company.  You shall have no right to require the Company to
     register the Warrants.  The Company will use its best efforts to register
     the shares of Common Stock underlying the Warrants and to keep such
     registration statement effective for a period of no less than two years.
     
          (d)  REMEDIES.  The Company stipulates that the remedies at law of the
     Warrantholder or any holder of Underlying Securities in the event of any
     default or threatened default by the Company in the performance of or
     compliance with any of the terms of this Warrant Agreement or the Warrants
     are not and will not be adequate and that such terms may be specifically
     enforced by a decree of the specific performance of any agreement contained
     herein or in the Warrants or by an injunction against a violation of any of
     the terms hereof or thereof or otherwise.
     
          (e)  EXCHANGE OF WARRANTS.  Subject to Subsection 3(a) hereof, upon
     surrender or exchange of any Warrant to the Company, the Company at its
     expense will promptly issue and deliver to or upon the order of the holder
     thereof a new Warrant of like tenor, in the name of such holder or as such
     holder (upon payment by such Warrantholder of any applicable transfer
     taxes) may direct, calling in the aggregate for the purchase of the




                                        7







     number of shares of the Underlying Securities called for on the face or
     faces of the Warrant or Warrants so surrendered.  The Warrants and all
     rights thereunder are transferable in whole or in part upon the books of
     the Company by the registered holder thereof subject to the provisions of
     Subsection 3(a) hereof, in person or by duly authorized attorney, upon
     surrender of the Warrant, duly endorsed, at the principal office of the
     Company.
     
          (f)  REPLACEMENT OF WARRANTS.  Upon receipt of evidence reasonably
     satisfactory to the Company of the loss, theft, destruction or mutilation
     of any Warrant, and in the case of any such loss, theft or destruction,
     upon delivery of an indemnity agreement reasonably satisfactory in form and
     amount to the Company, or in the case of such mutilation, upon surrender
     and cancellation of such Warrant, the Company, at the expense of the
     Warrantholder, will execute and deliver, in lieu thereof, a new Warrant of
     like tenor.
     
          (g)  REPORTING BY THE COMPANY.  The Company agrees that during the
     term of the Warrants and as long as you hold Underlying Securities, it will
     use its best efforts to keep current in the filing of all forms and other
     materials, if any, which it may be required to file with the appropriate
     regulatory authority pursuant to the Exchange Act and all other forms and
     reports required to be filed with any regulatory authority having
     jurisdiction over the Company.
     
          (h)  FRACTIONAL SHARES.  No fractional shares of Underlying Securities
     are to be issued upon the exercise of any Warrant, but the Company shall
     pay a cash adjustment in respect of any fraction of a share that would
     otherwise be issuable in an amount equal to such fraction multiplied by the
     closing market price per share of Underlying Securities on the day of
     exercise, as determined by the closing bid and asked price regular way on
     the principal national securities exchange on which the Underlying
     Securities is listed or admitted to trading, or if not listed or admitted
     to trading on any national securities exchange, the average of the highest
     reported bid and lowest reported asked price over the preceding 30-day
     period as furnished by the National Quotation Bureau Incorporated;
     provided, however, that if the Underlying Securities are not traded in such
     manner that the quotations referred to herein are available, the market
     price shall be deemed to be the fair market value of such Underlying
     Securities as reasonably determined by the Board of Directors.
     
8.   OTHER WARRANTHOLDERS.

     The Warrants are issued upon the following terms, to all of which each
holder or owner thereof by the taking thereof consents and agrees: (a) any
person who shall become a transferee, within the limitations on transfer imposed

Subsection 3(a) hereof and the other provisions hereof and thereupon shall be
authorized to represent himself as absolute owner thereof and, subject to the
restrictions contained in this Warrant Agreement, shall be empowered to transfer
absolute title by endorsement and delivery thereof to a permitted bonafide
purchaser for value; (b) each prior



                                        8







taker or owner waives and renounces all of his equities or rights in such
Warrant in favor of each such permitted bonafide purchaser, and each such
permitted bonafide purchaser shall acquire absolute title thereto and to all
rights presented thereby; (c) until such time as the respective Warrant is
transferred on the books of the Company, the Company may treat the registered
holder thereof as the absolute owner thereof for all purposes, notwithstanding
any notice to the contrary; and (d) all references to the words "you" and "your"
in this Warrant Agreement shall be deemed to apply with equal effect to any
person to whom a Warrant has been transferred in accordance with the terms
hereof, and where appropriate, to any person holding shares of the Underlying
