                                       2

1. Title to Warrant. Prior to the Termination Date and subject to compliance
with applicable laws, this Warrant and all rights hereunder are transferable, in
whole or in part, at the office or agency of the Corporation by the Holder in
person or by duly authorized attorney, upon surrender of this Warrant together
with the Assignment Form annexed hereto properly endorsed.

2. Authorization of Shares. The Corporation covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by this
Warrant will, upon exercise of the purchase rights represented by this Warrant,
be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges in respect of the issue thereof (other than taxes
in respect of any transfer occurring contemporaneously with such issue).

3. Exercise of Warrant.

     (a)  Except as provided in Section 4 herein, exercise of the purchase
          rights represented by this Warrant may be made at any time or times on
          or after the Initial Exercise Date and on or before the Termination
          Date by the surrender of this Warrant and the Notice of Exercise Form
          annexed hereto duly executed, at the office of the Corporation (or
          such other office or agency of the Corporation as it may designate by
          notice in writing to the registered Holder at the address of such
          Holder appearing on the books of the Corporation) and upon payment of
          the Exercise Price of the shares thereby purchased by wire transfer or
          cashier's check drawn on a United States bank, or by means of a
          cashless exercise, the Holder shall be entitled to receive a
          certificate for the number of Warrant Shares so purchased.
          Certificates for shares purchased hereunder shall be delivered to the
          Holder within three (3) Trading Days after the date on which this
          Warrant shall have been exercised as aforesaid. This Warrant shall be
          deemed to have been exercised and such certificate or certificates
          shall be deemed to have been issued, and Holder or any other person so
          designated to be named therein shall be deemed to have become a holder
          of record of such shares for all purposes, as of the date the Warrant
          has been exercised by payment to the Corporation of the Exercise Price
          and all taxes required to be paid by the Holder, if any, pursuant to
          Section 5 prior to the issuance of such shares, have been paid.

     (b)  If this Warrant shall have been exercised in part, the Corporation
          shall, at the time of delivery of the certificate or certificates
          representing Warrant Shares, deliver to Holder a new Warrant
          evidencing the rights of Holder to purchase the unpurchased Warrant
          Shares called for by this Warrant, which new Warrant shall in all
          other respects be identical with this Warrant.

     (c)  Notwithstanding anything herein to the contrary, in no event shall the
          Holder be permitted to exercise this Warrant for Warrant Shares to the
          extent that (i) the number of shares of Common Stock owned by such
          Holder (other than Warrant Shares issuable upon exercise of this
          Warrant) plus (ii) the number of Warrant Shares issuable upon exercise
          of this Warrant, would be equal to or exceed 4.999% of the number of
          shares of Common Stock then issued and outstanding, including shares
          issuable upon exercise of this Warrant held by such Holder after
          application of this Section 3(c). As used herein, beneficial ownership
          shall be

<PAGE>

                                       3

          determined in accordance with Section 13(d) of the Exchange Act. To
          the extent that the limitation contained in this Section 3(c) applies,
          the determination of whether this Warrant is exercisable (in relation
          to other securities owned by the Holder) and of which a portion of
          this Warrant is exercisable shall be in the sole discretion of such
          Holder, and the submission of a Notice of Exercise shall be deemed to
          be such Holder's determination of whether this Warrant is exercisable
          (in relation to other securities owned by such Holder) and of which
          portion of this Warrant is exercisable, in each case subject to such
          aggregate percentage limitation, and the Corporation shall have no
          obligation to verify or confirm the accuracy of such determination.
          Nothing contained herein shall be deemed to restrict the right of a
          Holder to exercise this Warrant into Warrant Shares at such time as
          such exercise will not violate the provisions of this Section 3(c).
          The provisions of this Section 3(c) may be waived by the Holder upon,
          at the election of the Holder, not less than 61 days' prior notice to
          the Corporation, and the provisions of this Section 3(c) shall
          continue to apply until such 61st day (or such later date, as
          determined by the Holder, as may be specified in such notice of
          waiver). No exercise of this Warrant in violation of this Section 3(c)
          but otherwise in accordance with this Warrant shall affect the status
          of the Warrant Shares as validly issued, fully-paid and nonassessable.

4. No Fractional Shares or Scrip. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant. As to any
fraction of a share which Holder would otherwise be entitled to purchase upon
such exercise, the Corporation shall pay a cash adjustment in respect of such
final fraction in an amount equal to such fraction multiplied by the Exercise
Price.

5. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares
shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such certificate, all of
which taxes and expenses shall be paid by the Corporation, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; and the Corporation
may require, as a condition thereto, the payment of a sum sufficient to
reimburse it for any transfer tax incidental thereto.

6. Closing of Books. The Corporation will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant.

7. Transfer, Division and Combination.

     (a)  Subject to compliance with any applicable securities laws, transfer of
          this Warrant and all rights hereunder, in whole or in part, shall be
          registered on the books of the Corporation to be maintained for such
          purpose, upon surrender of this Warrant at the principal office of the
          Corporation, together with a written assignment of this Warrant
          substantially in the form attached hereto duly executed by the Holder
          or its agent or attorney and funds sufficient to pay any transfer
          taxes payable upon

<PAGE>

                                       4

          the making of such transfer. In the event that the Holder wishes to
          transfer a portion of this Warrant, the Holder shall transfer at least
          25,000 shares underlying this Warrant to any such transferee. Upon
          such surrender and, if required, such payment, the Corporation shall
          execute and deliver a new Warrant or Warrants in the name of the
          assignee or assignees and in the denomination or denominations
          specified in such instrument of assignment, and shall issue to the
          assignor a new Warrant evidencing the portion of this Warrant not so
          assigned, and this Warrant shall promptly be cancelled. A Warrant, if
          properly assigned, may be exercised by a new holder for the purchase
          of Warrant Shares without having a new Warrant issued. Notwithstanding
          the above, the Holder shall not transfer this Warrant or any rights
          hereunder to any person or entity which is then engaged in a business
          that is in the reasonable judgement of the Corporation is in direct
          competition with the Corporation.

     (b)  This Warrant may be divided or combined with other Warrants upon
          presentation hereof at the aforesaid office of the Corporation,
          together with a written notice specifying the names and denominations
          in which new Warrants are to be issued, signed by the Holder or its
          agent or attorney. Subject to compliance with Section 7(a), as to any
          transfer which may be involved in such division or combination, the
          Corporation shall execute and deliver a new Warrant or Warrants in
          exchange for the Warrant or Warrants to be divided or combined in
          accordance with such notice.

     (c)  The Corporation shall prepare, issue and deliver at its own expense
          (other than transfer taxes) the new Warrant or Warrants under this
          Section 7.

     (d)  The Corporation agrees to maintain, at its aforesaid office, books for
          the registration and the registration of transfer of the Warrants.

8. No Rights as Shareholder until Exercise. This Warrant does not entitle the
Holder to any voting rights or other rights as a shareholder of the Corporation
prior to the exercise hereof. Upon the surrender of this Warrant and the payment
of the aggregate Exercise Price or by means of a cashless exercise, the Warrant
Shares so purchased shall be and be deemed to be issued to such Holder as the
record owner of such shares as of the close of business on the later of the date
of such surrender or payment.

9. Loss, Theft, Destruction or Mutilation of Warrant. The Corporation covenants
that upon receipt by the Corporation of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Corporation will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the expiration of any right required or granted herein
shall be a Saturday, Sunday or a

<PAGE>

                                       5

legal holiday, then such action may be taken or such right may be exercised on
the next succeeding day not a Saturday, Sunday or legal holiday.

11. Adjustments of Exercise Price and Number of Warrant Shares/Stock Splits,
etc. The number and kind of securities purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment from time to time
upon the happening of any of the following. In case the Corporation shall (i)
pay a dividend in shares of Common Stock or make a distribution in shares of
Common Stock to holders of its outstanding Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of shares, (iii)
combine its outstanding shares of Common Stock into a smaller number of shares
of Common Stock, or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, then the number of Warrant Shares
purchasable upon exercise of this Warrant immediately prior thereto shall be
adjusted so that the Holder shall be entitled to receive the kind and number of
Warrant Shares or other securities of the Corporation which it would have owned
or have been entitled to receive had such Warrant been exercised in advance
thereof. Upon each such adjustment of the kind and number of Warrant Shares or
other securities of the Corporation which are purchasable hereunder, the Holder
shall thereafter be entitled to purchase the number of Warrant Shares or other
securities resulting from such adjustment at an Exercise Price per Warrant Share
or other security obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of Warrant Shares purchasable
pursuant hereto immediately prior to such adjustment and dividing by the number
of Warrant Shares or other securities of the Corporation resulting from such
adjustment. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.

12. Reorganization, Reclassification, Merger, Consolidation or Disposition of
Assets. In case the Corporation shall reorganize its capital, reclassify its
capital stock, consolidate or merge with or into another corporation (where the
Corporation is not the surviving corporation or where there is a change in or
distribution with respect to the Common Stock of the Corporation), or sell,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Corporation, then the Holder shall have the right thereafter to receive,
at their option, (a) upon exercise of this Warrant, the number of shares of
Common Stock of the successor or acquiring corporation or of the Corporation, if
it is the surviving corporation, and Other Property receivable upon or as a
result of such reorganization, reclassification, merger, consolidation or
disposition of assets by a Holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such event, or (b) cash
equal to the value of this Warrant as determined in accordance with the
Black-Sholes option pricing formula. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Corporation) shall expressly assume
the due and punctual observance and performance of each and every covenant and
condition of this Warrant to be performed and observed by the Corporation and
all the obligations and liabilities hereunder, subject to such modifications as

<PAGE>

                                       6

may be deemed appropriate (as determined in good faith by resolution of the
Board of Directors of the Corporation) in order to provide for adjustments of
Warrant Shares for which this Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 12.
For purposes of this Section 12, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or assets over any other class of stock of such
corporation and which is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities which are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event and any
warrants or other rights to subscribe for or purchase any such stock. The
foregoing provisions of this Section 12 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

13. Voluntary Adjustment by the Corporation. The Corporation may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Corporation.

14. Notice of Adjustment. Whenever the number of Warrant Shares or number or
kind of securities or other property purchasable upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Corporation
shall promptly mail by registered or certified mail, return receipt requested,
to the Holder notice of such adjustment or adjustments setting forth the number
of Warrant Shares (and other securities or property) purchasable upon the
exercise of this Warrant and the Exercise Price of such Warrant Shares (and
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. Such notice, in the absence of
manifest error, shall be conclusive evidence of the correctness of such
adjustment.

15. Notice of Corporate Action. If at any time:

     (a) the Corporation shall take a record of the holders of its Common Stock
for the purpose of entitling them to receive a dividend or other distribution,
or any right to subscribe for or purchase any evidences of its indebtedness, any
shares of stock of any class or any other securities or property, or to receive
any other right, or

     (b) there shall be any capital reorganization of the Corporation, any
reclassification or recapitalization of the capital stock of the Corporation or
any consolidation or merger of the Corporation with, or any sale, transfer or
other disposition of all or substantially all the property, assets or business
of the Corporation to, another corporation or,

     (c) there shall be a voluntary or involuntary dissolution, liquidation or
winding up of the Corporation;

then, in any one or more of such cases, the Corporation shall give to Holder (i)
at least 20 days' prior written notice of the date on which a record date shall
be selected for such dividend, distribution or right or for determining rights
to vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer,

<PAGE>

                                       7

disposition, dissolution, liquidation or winding up, at least 20 days' prior
written notice of the date when the same shall take place. Such notice in
accordance with the foregoing clause also shall specify (i) the date on which
any such record is to be taken for the purpose of such dividend, distribution or
right, the date on which the holders of Common Stock shall be entitled to any
such dividend, distribution or right, and the amount and character thereof, and
(ii) the date on which any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up is to take place and the time, if any such time is to be fixed, as of which
the holders of Common Stock shall be entitled to exchange their Warrant Shares
for securities or other property deliverable upon such disposition, dissolution,
liquidation or winding up. Each such written notice shall be sufficiently given
if addressed to Holder at the last address of Holder appearing on the books of
the Corporation and delivered in accordance with Section 17(d).

16. Authorized Shares. The Corporation covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The
Corporation further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The
Corporation will take all such reasonable action as may be necessary to assure
that such Warrant Shares may be issued as provided herein without violation of
any applicable law or regulation, or of any requirements of the principal market
upon which the Common Stock may be listed.

     The Corporation shall not by any action, including, without limitation,
amending 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 this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder
against impairment. Without limiting the generality of the foregoing, the
Corporation will (a) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (b) take all such action as may be necessary or appropriate in order
that the Corporation may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant, and (c) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Corporation to perform its obligations under this Warrant.

     Before taking any action which would result in an adjustment in the number
of Warrant Shares for which this Warrant is exercisable or in the Exercise
Price, the Corporation shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

                                       8

17. Miscellaneous.

     (a)  Jurisdiction. This Warrant shall constitute a contract under the laws
          of Ontario, without regard to its conflict of law, principles or
          rules, and be subject to arbitration pursuant to the terms set forth
          in the Purchase Agreement.

     (b)  Restrictions. The Holder acknowledges that the Warrant Shares acquired
          upon the exercise of this Warrant, if not registered, will have
          restrictions upon resale imposed by state and federal securities laws.

     (c)  Nonwaiver and Expenses. No course of dealing or any delay or failure
          to exercise any right hereunder on the part of Holder shall operate as
          a waiver of such right or otherwise prejudice Holder's rights, powers
          or remedies, notwithstanding all rights hereunder terminate on the
          Termination Date. If the Corporation willfully and knowingly fails to
          comply with any provision of this Warrant, which results in any
          material damages to the Holder, the Corporation shall pay to Holder
          such amounts as shall be sufficient to cover any costs and expenses
          including, but not limited to, reasonable attorneys' fees, including
          those of appellate proceedings, incurred by Holder in collecting any
          amounts due pursuant hereto or in otherwise enforcing any of its
          rights, powers or remedies hereunder.

     (d)  Notices. Any notice, request or other document required or permitted
          to be given or delivered to the Holder by the Corporation shall be
          delivered in accordance with the notice provisions of the Purchase
          Agreement.

     (e)  Limitation of Liability. No provision hereof, in the absence of
          affirmative action by Holder to purchase Warrant Shares, and no
          enumeration herein of the rights or privileges of Holder, shall give
          rise to any liability of Holder for the purchase price of any Common
          Stock or as a stockholder of the Corporation, whether such liability
          is asserted by the Corporation or by creditors of the Corporation.

     (f)  Remedies. Holder, in addition to being entitled to exercise all rights
          granted by law, including recovery of damages, will be entitled to
          specific performance of its rights under this Warrant. The Corporation
          agrees that monetary damages would not be adequate compensation for
          any loss incurred by reason of a breach by it of the provisions of
          this Warrant and hereby agrees to waive the defense in any action for
          specific performance that a remedy at law would be adequate.

     (g)  Successors and Assigns. Subject to applicable securities laws, this
          Warrant and the rights and obligations evidenced hereby shall inure to
          the benefit of and be binding upon the successors of the Corporation
          and the successors and permitted assigns of Holder. The provisions of
          this Warrant are intended to be for the benefit of all Holders from
          time to time of this Warrant and shall be enforceable by any such
          Holder or holder of Warrant Shares.

     (h)  Amendment. This Warrant may be modified or amended or the provisions
          hereof waived with the written consent of the Corporation and the
          Holder.

<PAGE>

                                       9

     (i)  Severability. Wherever possible, each provision of this Warrant shall
          be interpreted in such manner as to be effective and valid under
          applicable law, but if any provision of this Warrant shall be
          prohibited by or invalid under applicable law, such provision shall be
          ineffective to the extent of such prohibition or invalidity, without
          invalidating the remainder of such provisions or the remaining
          provisions of this Warrant.

     (j)  Headings. The headings used in this Warrant are for the convenience of
          reference only and shall not, for any purpose, be deemed a part of
          this Warrant.
