1.   Purpose

     force effective September 29th, 1995.

2.   Number of Common Shares to be Offered

     Stock options granted under the Plan ("Options" or "Option") shall be for

     ("Option Shares" or "Option Share").  The maximum number of Common Shares
     that will be reserved for issuance and issued under this Plan shall not
     exceed 4,906,000 shares.  The following restrictions shall also apply to
     this Plan as well as all other plans or stock option agreements to which
     the Company may be a party;

     (i)    the aggregate number of Option Shares reserved for issuance pursuant
            to options granted to Insiders shall not exceed ten percent (10%) of
            the Outstanding Issue;

     (ii)   Insiders shall not be issued, within any one year period, a number
            of Option Shares which exceeds ten percent (10%) of the Outstanding
            Issue;

            within any one year period, a number of Option Shares which exceeds
            five percent (5%) of the Outstanding Issue; and

     (iv)   the number of Option Shares reserved for issuance pursuant to
            options to any one participant shall not exceed five percent (5%) of

     (i)    an insider of the Company as defined by the Securities Act (Ontario)
            as amended from time to time, other than a person who falls within

            officer of a subsidiary of the Company; and
<PAGE>

     (ii)   an Associate of any person who is an insider by virtue of Clause (i)
            of this definition; and

            "Outstanding Issue" means the number Of Common Shares of the Company
            that are outstanding immediately prior to any issuance of Options
            under this Plan or any issuance of Option Shares, as the case may
            be, excluding Option Shares issued pursuant to the Plan during the
            preceding one year period.

     Upon the expiration, surrender or termination, in whole or in part, of an
     unexercised Option, the Option Shares subject to such unexercised Option
     shall be available for other Options to be granted from time to time.

3.   Administration

     The Plan shall be administered by the Compensation Committee of the Board
     of Directors of the Company (the "Committee") who shall be appointed by and
     serve at the pleasure of the Board of Directors (the "Board"). The
     Committee shall have full power and authority, subject to the terms of the
     Plan, to grant Options on behalf of the Company; to designate the
     individuals who are to be granted Options (the "Optionees" or "Optionee");
     to set the date of grant, the number of Option Shares to be granted
     pursuant to each Option; and the other terms and conditions of the Options;
     and otherwise to interpret and construe the terms of the Plan. Any
     determination by the Committee shall be final and conclusive unless
     otherwise determined by the Board and, in any such event, such
     determination of the Board shall be final and conclusive. The day-to-day
     administration of the Plan may be delegated to such officers and employees
     of the Company as the Committee in its sole discretion shall determine.

4.   Terms and Conditions of Options

     (a)  Individuals Eligible to Receive Options.  The individuals eligible to
          receive Options shall be confined to such employees (including
          contract employees) and directors of the Company as shall be
          determined from time to time by the Committee.  In making such
          determination, the Committee shall consider the duties and
          responsibilities of the individual, his or her present and potential
          contribution to the success of the Company, and such other factors as
          the Committee shall deem relevant in accomplishing the purposes of the
          Plan. Participation in the Plan shall be entirely voluntary and any
          decision by any individual not to participate shall not affect such
          individual's employment with the Company.

     (b)  Grant of Options.  From time to time the Committee or the Board of
          Directors shall grant Options on behalf of the Company under the Plan.

     (c)  Option Price.  The purchase price ("Option Price") for an Option Share
          shall be the Market Price per Common Share as at the date of grant.
          "Market Price" per Common Share at any date shall be the closing price
          of the Common Shares on The Toronto Stock Exchange (the "Exchange")

          then listed or posted for trading on the Exchange, on such stock
          exchange in Canada on which such shares are listed and posted for
          trading as may be selected for such purpose by the Committee) on the
          trading date immediately preceding the date of grant. In the event
          that the Common Shares are not listed and posted for trading on any
          stock exchange in Canada, the market price shall be the last trading
          price of the Common Shares on National Association of Securities
          Dealers Quotations Systems ("NASDAQ") on the trading day immediately
          preceding the date of grant. In the event that the Common Shares are
          not trading on NASDAQ, the market price shall be determined by the
          Committee in its sole discretion.

     (d)  Exercise Period.  An Option may be exercised at any time or from time
          to time within such period as the Committee shall determine (the
          "Exercise Period"), but in no event shall such Exercise Period be
          greater than 10 years from the date of grant.  The Committee may, but
          shall not be required to, impose such conditions on the exercise of an
          Option as the Committee deems appropriate.

     (e)  Methods of Payment.  Payment for purchase of Option Shares shall be
          made in cash or by certified cheque.  Only full shares shall be issued
          under the Plan.

     (f)  Termination of Employment.  The following shall apply in the event
          that the employment of an Optionee is terminated on a date prior to
          the expiration of the Exercise Period ("Termination Date").  For
          purposes of the Plan, the transfer of an Optionee to a different
          position or office within the Company shall not be considered a
          termination.

          (i)    If the cause of termination is the voluntary retirement or
                 dismissal for cause of the Optionee, the Optionee's Option
                 shall terminate on the Termination Date. Provided that the
                 Chief Executive Officer of the Company may extend such period
                 for up to 30 days following the Termination Date prior to which
                 date the Optionee may exercise all or any part of the
                 Optionee's Option that has vested and is exercisable in
                 accordance with the provisions of Section 4(d) hereof.

          (ii)   If the cause of termination is other than the death, voluntary
                 retirement or dismissal for cause of the Optionee, the
                 Optionee's Option shall terminate 60 days following the
                 Termination Date prior to which date the Optionee may exercise
                 all or any part of the Optionee's Option that has vested and is
                 exercisable in accordance with the provisions of Section 4(d)
                 hereof. The Chief Executive Officer of the Company may extend
                 such period for up to an additional 30 days.

          (iii)  If the cause of termination is the death of the Optionee, the
                 Optionee's Option shall terminate six (6) months following the
                 Termination Date prior to which date the legal personal
                 representative(s) of the deceased Optionee may exercise such
                 portion of the Optionee's Option that has vested and is
                 exercisable in accordance with the provisions of Section 4(d)
                 hereof.

<PAGE>

          Notwithstanding the provisions of this paragraph (f), in no event may
          an Option be exercised after the expiration of the Exercise Period.

     (g)  Transferability.  An Option may not be assigned or transferred. Each
          Option will be exercisable during the lifetime of the Optionee only by
          the Optionee.  In the event of the death of an Optionee, the legal
          personal representative(s) of the deceased Optionee may exercise,
          within the period set out in Section 4(f)(ii) hereof, such portion of
          the Optionee's Option that would have been exercisable by the Optionee
          on the date of death in accordance with the provisions of Section 4(d)
          hereof.

     (h)  Reorganization and Recapitalization.  In the event of any subdivision,
          redivision or change of the Common Shares of the Company at any time
          prior to the expiration of the Exercise Period into a greater number
          of shares, the Company shall deliver at the time of any exercise
          thereafter of the Option hereby granted such additional number of
          shares as would have resulted from such subdivision, redivision or
          change if such exercise of the Option hereby granted had been prior to
          the date of such subdivision, redivision or change.

          In the event of any consolidation or change of the Common Shares of
          the Company at any time prior to the expiration of the Exercise Period
          into a lesser number of shares, the number of shares deliverable by
          the Company on any exercise thereafter of the Option hereby granted
          shall be reduced to such number of shares as would have resulted from
          such consolidation or change if such exercise of the Option hereby
          granted had been prior to the date of such consolidation or change.

5.   Amendment and Discontinuance

     The Committee shall have the right to amend or modify this Plan or to
     terminate this Plan at any time without notice provided that an Optionee's
     rights are not thereby materially adversely affected and subject to any
     approvals required under the applicable rules of any stock exchange upon
     which the Common Shares of the Company are or may be listed.

6.   Employment Non-Contractual

     Nothing in this option shall be construed as conferring upon the Optionee
     any right to continue in the service of the Company or any subsidiary of
     the Company.

7.   Rights as a Shareholder

     The Optionee shall not have any rights as a shareholder with respect to any
     Option Shares issuable upon exercise of this Option until this Option has
     been validly exercised and the purchase price for such Option Share has
     been paid in full.

<PAGE>

8.   Nontransferability

     The Optionee's rights under this option are not assignable or transferable
     by the Optionee during the Optionee's lifetime and are exercisable during
     the Optionee's lifetime only by the Optionee.

9.   Corporate Action

     Nothing contained herein shall be construed so as to prevent the Company or
     any subsidiary of the Company from taking corporate action which is deemed
     by the Company or the subsidiary to be appropriate or in its best interest,
     whether or not such action would have an adverse effect on the Option.

10.  Government Regulation

     Option is subject to:

          undertakings as to future dealings in such Common Shares as the
          Company determines to be necessary or advisable in order to safeguard
          against the violation of the securities law of any jurisdiction.

     In this connection, the Company shall take all reasonable steps to obtain
     such approvals and registrations as may be necessary for the issuance of
     such Common Shares in compliance with applicable securities law and for the
     listing of such Common Shares on any stock exchange on which such Common
     Shares are then listed.

11.  Approvals

     Options granted prior to such acceptance shall be conditional upon such

     may be exercised unless such acceptance is given and such conditions are
     complied with.
