Shares provided that the aggregate number of Common Shares reserved for issuance
under this Plan, subject to adjustment or increase of such number pursuant to
the provisions of Article 6 hereof, together with any Common Shares reserved for
issuance under any options or warrants for services or employee stock purchase
or stock option plans or any other plans, shall not exceed 4,280,3441 Common

person under the Plan, together with any Common Shares reserved for issuance

circular to the holders of all or substantially all of the outstanding Common
Shares, from and as at the date of mailing of that circular (the "Mailing
Date"), all Options that are then outstanding under

     common shares reserved for issuance thereunder to 4,280,344 common shares.
<PAGE>

the Plan, whether or not theretofore exercisable, shall thereupon automatically
become exercisable for a period of 30 days following the Mailing Date, or such
other period as the Board may, in its sole discretion, from time to time on or
after the date of announcement of that take-over bid select as appropriate in
the circumstances by notice given in writing to the holders of such Options, at
the end of which period all Options which have not then been exercised shall
revert back to and remain as they were before that take-over bid was announced
or made.

5.   Exercise of Option
     ------------------

          Subject to the provisions of the Plan and the terms of the granting of
the Option, an Option or a portion thereof may be exercised from time to time by
delivery to the Corporation at its registered office of a notice in writing
signed by the Participant or the Participant's legal personal representative and
addressed to the Corporation. This notice shall state the intention of the
Participant or the Participant's legal personal representative to exercise the
said Option or a portion thereof, the number of Common Shares in respect of

exercise.

6.   Adjustments in Shares
     ---------------------

6.1       Appropriate adjustments in the number of Common Shares subject to the
Plan and, as regards Options granted or to be granted, in the number of Common
Shares optioned and in the Option Price, shall be made by the Board to give
effect to adjustments in the number of Common Shares resulting from
subdivisions, consolidations or reclassifications of the Common Shares, the
payment of stock dividends by the Corporation (other than dividends in the
ordinary course) or other relevant changes in the authorized or issued capital
of the Corporation, which changes occur subsequent to the approval of the Plan
by the Board.

6.2       Options granted to Participants hereunder are non-assignable and,
except in the case of the death of a Participant, are exercisable only by the
Participant to whom the Options have been granted.

7.   Decisions of the Board
     ----------------------

          All decisions and interpretations of the Board respecting the Plan or
Options granted thereunder shall be conclusive and binding on the Corporation

8.   Termination of Employment/Death
     -------------------------------

8.1       An Option, and all rights to purchase Common Shares pursuant thereto,
shall expire and terminate immediately upon the termination of the employment of
the Participant by the Corporation or, if applicable, any subsidiary of the
Corporation, or, if the Participant is a director of the Corporation or any
subsidiary of the Corporation, immediately upon the Participant ceasing to be a
director, other than in the circumstances referred to below.

8.2       If, before the expiry of an Option in accordance with the terms
thereof:

     (i)  in the case of a Participant who is an employee of the Corporation or
          any of its subsidiaries, the employment of the Participant by the
          Corporation or by any of its subsidiaries shall terminate for any
          reason whatsoever other than termination by the Corporation for cause
          or the voluntary resignation of the Participant but including, for
          greater certainty, termination by reason of the death of the
          Participant; or

     (ii) in the case of a Participant who is a director of the Corporation or
          any of its subsidiaries and not an employee, such director shall cease
          to be a director of the Corporation or any subsidiary of the
          Corporation for any reason;

such Option may, subject to the terms thereof and any other terms of the Plan,
be exercised, if the Participant is deceased, by the legal personal
representative(s) of the Participant's estate or, if the Participant is alive,
by the Participant, at any time within three months of the date of termination
of employment or, where applicable, the date a Participant ceases to be a
director.

8.3       The Plan does not confer upon a Participant any right with respect to
continuation of employment by the Corporation or any subsidiary, nor does it
interfere in any way with the right of the Participant or the Corporation or any
subsidiary of the Corporation to terminate the Participant's employment at any
time.

8.4       Options shall not be affected by any change of employment of the
Participant where the Participant continues to be employed by the Corporation or
any of its subsidiaries.

9.   Amendment or Discontinuance of Plan
     -----------------------------------

          The Board may amend or discontinue the Plan at any time without the
consent of the Participants provided that such amendment shall not alter or
impair in any materially adverse manner any Option previously granted under the
Plan except as permitted by the provisions of Article 6 hereof.

10.  Government Regulation
     ---------------------

          The Corporation's obligation to issue and deliver Common Shares under
any Option is subject to:

     (a)  the satisfaction of all requirements under applicable securities laws
          in respect thereof and obtaining all regulatory approvals as the
          Corporation shall determine to be necessary or advisable in connection
          with the authorization, issuance or sale thereof;

     (b)  the admission of such Common Shares to listing on any stock exchange
          on which such Common Shares may then be listed; and

     (c)  the receipt from the Participant of such representations, agreements
          and undertakings as to future dealings in such Common Shares as the
          Corporation determines to be necessary or advisable in order to
          safeguard against the violation of the securities laws of any
          jurisdiction.

In this connection, the Corporation 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 laws and for the listing
of such Common Shares on any stock exchange on which such Common Shares are then
listed.

11.  Participants' Rights
     --------------------

          A Participant shall not have any rights as a shareholder of the
Corporation until the issuance of a certificate for Common Shares upon the
exercise of an Option or a portion thereof, and then only with respect to the
Common Shares represented by such certificate or certificates.

                  accident, or as may be otherwise approved from time to time by
                  the Board. The Executive shall be bound by and shall
                  faithfully observe and abide by all of the rules, regulations
                  and corporate policies of Bracknell from time to time in force
                  which are brought to the attention of the Executive or of

                  salary of $450,000 (the "Annual Salary"), payable in

                  deductions as shall be required to be withheld by applicable
                  law and regulation. The Annual Salary payable to the Executive
                  by Bracknell will be reviewed annually by the Board in
                  accordance with the policies and procedures that apply to
                  other senior officers of Bracknell in order to determine
                  whether any change to the Annual Salary is warranted;
                  provided, however, that under no circumstances will the Annual
                  Salary paid to the Executive be less than the amount payable
                  as at the Effective Date as set forth above.

         b)       Annual Bonuses. The Executive shall be paid, by Bracknell, an
                  annual bonus in such amount as shall be determined by the
                  Board or by a committee of the Board in accordance with the
                  policies and procedures that apply to other senior officers of
                  Bracknell, however, that unless the Board determines otherwise
                  in its sole discretion, such amount shall not exceed 100% of
                  the Executive's Annual Salary.

5)       Stock Options

         a)       Conventional Options. As soon as is reasonably practicable on
                  or after the Effective Date, Bracknell shall grant the
                  Executive an option to purchase 300,000 Shares in accordance
                  with the stock option plan of Bracknell (the "Conventional
                  Options"). The exercise price of the Conventional Options
                  shall be the closing price for the Shares on the trading day
                  immediately preceding the date of grant of those options, as
                  quoted on The Toronto Stock Exchange. Except as provided in
                  Section 9(f) below, on each of the first three anniversary
                  dates of the grant of the Conventional Options, the Executive
                  shall acquire the right to purchase one-third of the Shares
                  subject to the Conventional Options. Except as otherwise set
                  out herein, the Conventional Options shall expire ten years
                  from the date of grant. Except as set forth in Section 9(f)
                  below, all other terms and conditions of the Conventional
                  Options,

                                      -5-

                  such as events of forfeiture, shall be as set forth in the
                  stock option plan of Bracknell pursuant to which the
                  Conventional Options were granted. The Executive acknowledges
                  having received a copy of such stock option plan, as presently
                  in effect.

         b)       Granting of Performance Options. As soon as is reasonably
                  practicable on or after the Effective Date, Bracknell shall
                  grant the Executive options (the "Performance Options") to
                  purchase an additional 300,000 Shares in accordance with the
                  stock option plan of Bracknell (such date of grant hereinafter
                  referred to as the "Date of Grant"). The exercise price
                  ("Exercise Price") of the Performance Options shall be the
                  closing price for the Shares on the trading day immediately
                  preceding the Date of Grant, as quoted on The Toronto Stock
                  Exchange. All of the Performance Options shall vest on the
                  seventh anniversary of the Date of Grant, unless vesting is
                  otherwise accelerated as follows. One-third of the Performance
                  Options will become eligible to vest on each of the first,
                  second and third anniversaries of the Date of Grant
                  (respectively, "Tranche One", "Tranche Two", and "Tranche
                  Three"), as described in more detail below.

         c)       Vesting of Performance Options in Year One. Tranche One of the
                  Performance Options shall vest on the first anniversary date
                  of the Date of Grant, provided that the trading price of the
                  Shares at any time during such first year from the Date of
                  Grant is at least 120% of the Exercise Price. In the event
                  that Tranche One of the Performance Options does not vest as
                  described above, then such tranche remains eligible to vest
                  prior to or upon the third anniversary of the Date of Grant,
                  as described below.

         d)       Vesting of Performance Options in Year Two. Tranche Two and
                  Tranche One (if not already vested) of the Performance Options
                  shall vest on the second anniversary date of the Date of
                  Grant, provided that the trading price of the Shares at any
                  time during such second year from the Date of Grant is at
                  least 144% of the Exercise Price. In the event that Tranche
                  One or Tranche Two of the Performance Options do not vest as
                  described above, then such tranches remain eligible to vest
                  upon the third anniversary of the Date of Grant, as described
                  below.

         e)       Vesting of Performance Options in Year Three. Tranche Three,
                  and any Performance Options not already vested, shall vest on
                  the third anniversary date of the Date of Grant, provided that
                  the trading price of the Shares at any time during such third
                  year from the Date of Grant is at least 173% of the Exercise
                  Price.

                                      -6-

         f)       Calculation of Trading Price for Performance Options. For the
                  purposes of Sections 5(c) to (e) above, the trading price of
                  the Shares on or as at any date shall be determined based on a
                  simple average of the closing price of the Shares on The
                  Toronto Stock Exchange on each trading day during the 20
                  trading day period ending on the business day prior to the
                  applicable date. In the event that the Shares do not trade on
                  any of such trading days, the average of the closing bid and
                  closing ask prices on The Toronto Stock Exchange on such date
                  shall be used as the closing price for that date.

         g)       Expiration of Performance Options. All Performance Options
                  which have not vested by the third anniversary date of the
                  Date of Grant will in any event vest on the seventh
                  anniversary of the Date of Grant. Except as otherwise set out
                  herein, all Performance Options which have vested will expire
                  ten years from the Date of Grant. Except as set forth in
                  Section 9(f) below, all other terms and conditions of the
                  Performance Options, such as events of forfeiture, shall be as
                  set forth in the stock option plan of Bracknell pursuant to
                  which the Performance Options were granted.

6)       Expenses

         Subject to such policies as may from time to time be established by the
         Board or a committee of the Board, Bracknell shall pay or reimburse the
         Executive for all reasonable travelling and other out-of-pocket
         expenses actually incurred or paid by the Executive in the performance
         of the Executive's duties as an officer of Bracknell upon presentation
         of such expense statements or vouchers or such other supporting
         information as Bracknell may require.

7)       Benefits

         a)       Automobile. Bracknell shall provide the Executive with a
                  leased automobile for his use, or an automobile allowance in
                  accordance with Bracknell's policies for its senior executives
                  in place from time to time. Bracknell shall pay or reimburse
                  the Executive for all reasonable operating expenses such as
                  gas, maintenance, parking and insurance incurred or paid by
                  the Executive in connection therewith.

         b)       Health Club. Bracknell will pay or reimburse the Executive for
                  all reasonable expenses paid or incurred by the Executive in
                  respect of membership fees at a health club, golf club or
                  similar organization to be used by the Executive for health
                  and dinner purposes.

                                      -7-

         c)       Benefits. The Executive shall be entitled to fully participate
                  in all other benefit plans available to senior executives of
                  Bracknell from time to time including, without limitation,
                  Bracknell's' medical, dental, insurance and similar programs.

8)       Vacation

         During the term of this Agreement, the Executive will be entitled to 4
         weeks of paid vacation per calendar year.

9)       Termination of Employment

         The following terms and provisions shall apply to the termination of
         the Executive's employment hereunder:

         a)       Termination For Cause. Bracknell may at any time terminate the
                  employment of the Executive for cause without any requirement
                  of a notice period and without payment of any compensation of
                  any nature or kind (including, without limitation, by way of
                  anticipated earnings, damages or payment in lieu of notice).
                  Notwithstanding the foregoing, in the event that any portion
                  of the Executive's Annual Salary has been earned but not paid
                  or any expenses referred to in Sections 6 or 7 have been
                  incurred by the Executive but not reimbursed, in each case to
                  the date of termination of his employment, together with any
                  amount to which the Executive is entitled under the Employment
                  Standards Act (Ontario), as amended and enforced from time to
                  time, to the extent that the same cannot be waived by the
                  Executive, such amounts shall be paid to the Executive within
                  15 business days following such date of termination.

         b)       Permanent Incapacity. In the event of the Permanent Incapacity
                  of the Executive, his employment may thereupon be terminated
                  by Bracknell without payment of any compensation of any nature
                  or kind (including, without limitation, by way of anticipated
                  earnings, damages or payment in lieu of notice); provided
                  that, in such event, Bracknell shall pay or cause to be paid
                  to the Executive the amounts specified in any benefit and
                  insurance plans applicable to the Executive as being payable
                  in the event of the permanent incapacity or disability of the
                  Executive, such sums to be paid in accordance with the
                  provisions of those plans as then in effect.

         c)       Death. If the Executive's employment is terminated by reason
                  of the Executive's death, the Executive's estate will be
                  entitled to receive and Bracknell shall pay or cause to be
                  paid to

                                      -8-

                  them or it, as the case may be, the amounts specified in the
                  benefit and insurance plans of Bracknell applicable to the
                  Executive, such sums to be paid in accordance with the
                  provisions of those plans as then in effect.

         d)       Termination by Executive. The Executive may terminate his
                  employment with Bracknell upon giving 30 days' written notice
                  or such shorter period of notice as Bracknell may accept. The
                  Executive shall not be entitled to any severance payment other
                  than the Annual Salary earned by the Executive but not paid
                  before the date of termination and any expenses referred to in
                  Section 6 or 7 incurred by the Executive but not yet
                  reimbursed, in each case to the date of termination, together
                  with any amount to which the Executive is entitled under the
                  Employment Standards Act (Ontario), as amended and in force
                  from time to time, to the extent that the same cannot be
                  waived by the Executive.

         e)       Other Termination by Bracknell. Bracknell may terminate the
                  Executive's employment at any time for any reason other than
                  as contemplated above in this Section 9 by providing written
                  notice to the Executive to that effect, in which event the
                  termination shall take effect as at such time as such notice
                  is received by the Executive. In the event that the
                  Executive's employment is so terminated by Bracknell, the
                  Executive shall be entitled to receive an amount by way of
                  lump sum payment equal to the aggregate of (i) 2.5 times the
                  Executive's Annual Salary then in effect, plus (ii) 2.5 times
                  the Executive's Annual Bonus Amount. For these purposes, the
                  term Annual Bonus Amount means, at any time, the average of
                  the annual cash bonuses paid to the Executive by Bracknell in
                  respect of the two completed fiscal years next preceding the
                  date of termination of his employment pursuant to Section 4(b)
                  above; provided, however, that if there is only one completed
                  fiscal year between the date hereof and the date of
                  termination of the Executive's employment, the bonus paid to
                  the Executive in respect of that fiscal year shall be the
                  Annual Bonus Amount. The payment described in this Section
                  9(e) is the only severance payment or payment in lieu of
                  notice that the Executive will be entitled to receive in the
                  event of the termination of his employment on the basis
                  contemplated in this Section 9(e).

         f)       Change of Control. In the event that the Executive's
                  employment with Bracknell is terminated by Bracknell without
                  cause (whether expressly or constructively) within three
                  months following the occurrence of a Change in Control, the
                  Executive shall be entitled to receive an amount by way of
                  lump sum payment equal to the aggregate of (i) 2.5 times the
                  Executive's Annual Salary then in effect, plus (ii) 2.5 times
                  the Executive's Annual Bonus Amount. For these purposes, the
                  term Annual Bonus Amount means, at any time, the average of
                  the annual cash bonuses paid to the Executive by Bracknell in
                  respect of the two
<PAGE>

                                      -9-

                  completed fiscal years next preceding the date of termination
                  of his employment pursuant to Section 4(b) above; provided,
                  however, that if there is only one completed fiscal year
                  between the date hereof and the date of termination of the
                  Executive's employment, the bonus paid to the Executive in
                  respect of that fiscal year shall be the Annual Bonus Amount.
                  The payment described in this Section 9(f) is the only
                  severance payment or payment in lieu of notice that the
                  Executive will be entitled to receive in the event of the
                  termination of his employment on the basis contemplated in
                  this Section 9(f). A constructive termination of employment
                  shall include a transfer involving a significant geographic
                  relocation, a fundamental demotion involving reduced
                  responsibilities and/or positioning within the corporate
                  hierarchy, or reductions in salary, bonus opportunity and/or
                  employee benefits.

         g)       Stock Options. In the event that the Executive's employment
                  with Bracknell is terminated as contemplated above in this
                  Section 9 or terminates as contemplated in Section 2, the
                  right of the Executive or his estate, as the case may be, to
                  retain and exercise vested or unvested stock options then held
                  by the Executive shall be determined in accordance with the
                  stock option plan pursuant to which those stock options were
                  granted. Notwithstanding the foregoing or any other provision
                  of this Agreement:

                  i)       in the event that the Executive's employment with
                           Bracknell is terminated by Bracknell as contemplated
                           above in Section 9(f) within three months following
                           the occurrence of a Change in Control, all unvested
                           Conventional Options and Performance Options held by
                           the Executive shall automatically vest on the date
                           the Executive is so terminated or on such earlier
                           date as the Board may in its sole discretion
                           determine; and

                  ii)      in the event that the Executive's employment with
                           Bracknell is not terminated as contemplated in
                           Section 9(f) but is terminated as contemplated in
                           Section 9(e), all unvested Conventional Options then
                           held by the Executive shall automatically vest on the
                           date the Executive is so terminated;

                  iii)     and at any time prior to the expiry of the three
                           month period following the date upon which the
                           Executive is so terminated, the Executive will have
                           the right to exercise all Conventional Options and
                           all Performance Options that were vested on or prior
                           to the date upon which the Executive is so
                           terminated, at which time all unexercised options
                           will be forfeited.

                                      -10-

         h)       Statutory Deductions. All payments required to be made to the
                  Executive or his estate under this Section 9 shall be made net
                  of all deductions required to be withheld by applicable law
                  and regulation.

         i)       Fair and Reasonable, etc. The parties acknowledge and agree
                  that the payment provisions contained in this Section 9 above
                  are fair and reasonable and the Executive acknowledges and
                  agrees that such payments are inclusive of any notice or pay
