conditions hereinafter set forth, at any time on or after that date on which the

"Exercise  Price") under this Warrant shall be $___________.  The Exercise Price
and the number of shares for which the Warrant is  exercisable  shall be subject
to adjustment as provided herein.

Title to Warrant.  Prior to the Termination  Date and subject to compliance with
applicable  laws,  this Warrant and all rights  hereunder  are  non-transferable
without the express  written  consent of the Company.  Such consent will only be
considered  upon  presentation of the request by Holder and  acknowledgement  by
Holder and the proposed  transferee of the requirements  and restrictions  under
this Warrant and any subsequent amendments or collateral agreements.

Authorization of Shares.  The Company  covenants that all shares of Common Stock
which may be issued upon the  exercise  of rights  represented  by this  Warrant
will,  upon  exercise  of the  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).

Exercise of Warrant.

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 before the close of business on the Termination Date
by the surrender of this Warrant and the Notice of Exercise Form annexed  hereto
duly  executed,  at the office of the Company (or such other office or agency of
the Company as it may  designate by notice in writing to the  registered  holder
hereof at the address of such holder  appearing on the books of the Company) and
upon  payment of the  Exercise  Price of the shares  thereby  purchased  by wire
transfer or  cashier's  check drawn on a United  States or  Canadian  bank,  the
holder of this Warrant shall be entitled to receive a certificate for the number
of  shares of Common  Stock so  purchased.  Certificates  for  shares  purchased
hereunder  shall be delivered to the holder hereof 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 Company of the Exercise Price and all taxes required
to be paid by Holder,  if any,  pursuant  to Section 5 prior to the  issuance of
such shares, have been paid.

                                       15
<PAGE>

This  Warrant  shall also be  exercisable  by means of a "cashless  exercise" in
which the holder  shall be entitled to receive a  certificate  for the number of
shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the average of the high and low trading  prices per share of Common  Stock
on the  Trading Day  preceding  the date of such  election  on the Nasdaq  Stock
Market,  or if the Common Stock is not traded on the Nasdaq Stock  Market,  then
the principal market in terms of volume, and converted into US Dollars;

(B) =  the Exercise Price of the Warrants; and

(X) = the number of shares  issuable upon exercise of the Warrants in accordance
with the terms of this Warrant.

If this Warrant shall have been  exercised in part,  the Company  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 shares of Common Stock called for by this Warrant, which new Warrant
shall in all other respects be identical with this Warrant.

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 Company shall pay a cash adjustment in respect of such final
fraction in an amount equal to the Exercise Price.

Charges, Taxes and Expenses. Issuance of certificates for shares of Common Stock
upon the  exercise of this Warrant  shall be made  without  charge to the holder
hereof 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 Company,  and such certificates shall be issued in the name of the holder
of this  Warrant  or in such name or names as may be  directed  by the holder of
this Warrant;  provided,  however,  that in the event certificates for shares of
Common  Stock are to be issued in a name  other  than the name of the  holder of
this Warrant, this Warrant when surrendered for exercise shall be accompanied by
the Assignment Form attached hereto duly executed by the holder hereof;  and the
Company may require, as a condition thereto,  the payment of a sum sufficient to
reimburse it for any transfer tax incidental thereto.

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

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  Company  to be  maintained  for such
         purpose,  upon surrender of this Warrant at the principal office of the
         Company,   together   with  a  written   assignment   of  this  Warrant
         substantially  in the form  attached  hereto duly executed by Holder or
         its agent or attorney and funds  sufficient  to pay any transfer  taxes
         payable upon the making of such  transfer.  Upon such surrender and, if
         required,  such  payment,  the Company  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 shares of Common  Stock
         without having a new Warrant issued.

(b)      This  Warrant  may be divided or  combined  with  other  Warrants  upon
         presentation  hereof at the aforesaid  office of the Company,  together
         with a written notice  specifying the names and  denominations in which
         new  Warrants  are to be  issued,  signed  by  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 Company
         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 Company shall prepare,  issue and deliver at its own expense (other
         than transfer taxes) the new Warrant or Warrants under this Section 7.

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

                                       16

No Rights as  Shareholder  until  Exercise.  This  Warrant  does not entitle the
holder  hereof to any  voting  rights or other  rights as a  shareholder  of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate  Exercise Price,  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.

Loss,  Theft,  Destruction or Mutilation of Warrant.  The Company covenants that
upon  receipt by the Company of evidence  reasonably  satisfactory  to it of the
loss, theft,  destruction or mutilation of this Warrant certificate 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 Company  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.

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

Adjustments  of Exercise Price and Number of Warrant  Shares.  (a) 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 Company 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 of Common  Stock,  (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 of this  Warrant  shall be  entitled to receive the
kind and number of Warrant  Shares or other  securities  of the Company which he
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  Company  which are  purchasable
hereunder,  the holder of this Warrant 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 Company 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.

Reorganization,   Reclassification,  Merger,  Consolidation  or  Disposition  of
Assets. In case the Company shall reorganize its capital, reclassify its capital
stock,  consolidate or merge with or into another corporation (where the Company
is not the surviving  corporation or where there is a change in or  distribution
with respect to the Common Stock of the Company), 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 Company,  then Holder shall
have the right thereafter to receive,  upon exercise of this Warrant, the number
of shares of common stock of the  successor or acquiring  corporation  or of the
Company, 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.  In case of
any such reorganization,  reclassification, merger, consolidation or disposition
of assets,  the successor or acquiring  corporation  (if other than the Company)
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 Company and all the obligations and liabilities  hereunder,  subject to such
modifications  as may be deemed  appropriate  (as  determined  in good  faith by
resolution  of the Board of  Directors  of the  Company) in order to provide for
adjustments  of shares of Common  Stock for which this  Warrant  is  exercisable
which shall be as nearly  equivalent as practicable to the adjustments  provided
for in this Section 11. For purposes of this  Section 11,  "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

                                       17
<PAGE>

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 11 shall  similarly
apply to successive reorganizations,  reclassifications, mergers, consolidations
or disposition of assets.

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 Company shall promptly
mail by registered or certified mail, return receipt requested, to the holder of
this Warrant 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.

Notice of Corporate Action.  If at any time:

(a)      the Company  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  Company,  any
         reclassification  or  recapitalization  of  the  capital  stock  of the
         Company or any  consolidation  or merger of the  Company  with,  or any
         sale,  transfer or other  disposition of all or  substantially  all the
         property, assets or business of the Company to, another corporation or,

(c)      there shall be a voluntary or involuntary  dissolution,  liquidation or
         winding up of the Company;  then, in any one or more of such cases, the
         Company shall give to Holder (i) at least 10 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, disposition, dissolution, liquidation or winding up, at
         least 10 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 shares of Common Stock 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
         Company and delivered in accordance with Section 16(d).

Authorized  Shares.  The Company 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 Company 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 Company 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 Company  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
Company  will (a) not  increase  the par value of any  shares  of  Common  Stock
receivable  upon the exercise of this Warrant 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 Company may
validly and legally  issue fully paid and  nonassessable  shares of Common Stock
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
Company to perform its obligations under this Warrant.

                                       18
