     fraction the numerator of which shall be the number of days from the
     closing date of the transactions contemplated by the Offer to and including
     December 31, 1998 and the denominator of which shall be 365.

     3.   Administration

          (a) The Plan shall be administered by the Compensation Committee, as
     such committee is constituted from time to time. Action by the Compensation
     Committee with respect to the Plan shall require the affirmative vote of a
     majority of all of its members.

          (b) Subject to the terms and conditions of the Plan, the Compensation
     Committee shall have the power:

               (i) To construe and interpret the Plan and to establish, amend
          and revoke rules and regulations for the administration of the Plan
          (including, without limitation, to correct any defect or supply any
          omission, or reconcile any inconsistency, in the Plan) in the manner
          and to the extent the Compensation Committee shall deem necessary or
          expedient to make the Plan fully effective; and

               (ii) Generally, to exercise such powers and to perform such acts
          as are deemed necessary or expedient to promote the best interests of
          S&Y, Lasiris and the Participants with respect to the Plan.



                                       3




     All decisions and determinations by the Compensation Committee in the
exercise of these powers shall be final and binding upon Lasiris and the
Participants.


     4.   Awards

     With respect to each Fiscal Year described above, the Compensation
Committee shall award to the Participants, the entire Aggregate Award Amount
determined in accordance with Section 2 above. Such awards shall be distributed
by Lasiris to the Participants no later than thirty (30) days after the delivery
of Audited Financial Statements for the pertinent Fiscal Year. In no event shall
the aggregate amount of cash awards made to the Participants with respect to any
such Fiscal Year exceed the Aggregate Award Amount for such Fiscal Year. Each
participant shall have the right to receive such award in cash or in
Exchangeable Shares (as defined in the Offer). In the event that any Participant
elects to receive an award in the form of Exchangeable Shares, the number of
Exchangeable Shares deliverable to such Participant shall be equal to the
quotient of (i) the amount of the award payable to such Participant divided by
(ii) the then current Fair Market Value (as defined below) of the Buyer Stock
(as defined in the Offer). For the purposes of this Plan, with respect to Buyer
Stock, "Fair Market Value" shall mean, as of any date, the average of the
closing prices for Buyer Stock on the Nasdaq SmallCap Market for the sixty (60)
days prior to the date of determination.


     5.   Eligibility

     Awards under the Plan shall be made solely to the Participants set forth on
Exhibit A, as such Exhibit is amended from time to time by the Compensation
Committee. No person who is not an employee of Lasiris on the last day of any
Fiscal Year (a "Terminated Participant") shall be entitled to receive any award
under the Plan with respect to such Fiscal Year, regardless of whether such
person is listed as a Participant on Exhibit A, unless such Terminated
Participant's employment with Lasiris was terminated under circumstances
constituting a breach by Lasiris of the Employment and Non-Competition Agreement
between such Terminated Participant and Lasiris, if any. The portion of the
Aggregate Award Amount that would otherwise be payable to a Terminated
Participant, but for the termination of his or her employment, shall be
available for distribution to Participants hereunder.


     6.   Taxation of Awards

     Lasiris shall undertake to make deductions, withholdings and tax reports
with respect to awards under the Plan to the extent that it reasonably and in
good faith believes that it is required to make such deductions, withholdings
and tax reports. Payments under the Plan shall be in amounts net of any such
deductions or withholdings. Nothing in the Plan shall be


                                       4



construed to require Lasiris to make any payments to compensate any Participant
for any adverse tax effect associated with any awards or for any deduction or
withholding from any awards.

     7.   Amendment of the Plan

     The Board of Directors of the Company, the Board of Directors of S&Y or the
Compensation Committee, with the written consent of a majority of the
Participants, may discontinue or amend the Plan at any time, or from time to
time.

     8.   Nonexclusivity of the Plan

     The adoption of the Plan by the Board of Directors shall not be construed
as creating any limitations on the power of the Board of Directors or the
Compensation Committee to adopt such other incentive arrangements as it may deem
desirable, including, without limitation, the granting of cash bonuses or awards
otherwise than under the Plan. The Plan shall not under any circumstances be
deemed to confer upon any Participant or other employee any right to continued
employment with the Company or S&Y.

     9.   Governing Law

     This Agreement shall be construed under and governed by the internal laws
of the Provinces of Quebec, Canada and the federal laws of Canada applicable
therein without regard to its conflict of laws provisions.

     10.  Effective Date of the Plan; Duration of the Plan

     The Plan shall become effective upon the date that it is approved by the
Board of Directors. The Plan shall expire, and no further awards shall be made
under the Plan, after the date on which the awards, if any, with respect to the
Fiscal year ending December 31, 2000 are made.
