Item 2.  Acquisition or Disposition of Assets.

     As of May 13, 1998, Stocker & Yale, Inc. (the "Company") acquired Lasiris,
Inc., a Canadian manufacturer of industrial lasers for the machine vision and
industrial inspection industries. The Company acquired Lasiris through Lasiris
Holdings, Inc., a newly-formed New Brunswick corporation and a subsidiary of the
Company ("LHI") for a total purchase price of approximately $5.3 million ($7.7
million (CDN)). The purchase price was paid 40% in shares of LHI's capital stock
which is exchangeable for shares of the Company's common stock and the balance
in cash. The Company financed the cash portion of the consideration through (i)
a private placement of 350,000 shares of the Company's common stock at a price
per share of $3.50, (ii) a loan in the amount of $750,000 from Danvers Savings
Bank which is secured by a second mortgage interest in the Company's
headquarters, (iii) a loan to Lasiris of approximately $800,000 pursuant to a
credit agreement with the Toronto Dominion Bank and (iv) cash available to the
Company upon the prepayment by Beverly Hospital Corp. of obligations owed to the
Company. The Company intends to operate Lasiris as a wholly-owned Canadian
subsidiary. The Company's management believes that Lasiris' business fits with
the Company's corporate strategy to build an industrial lighting company which
offers customers one-stop shopping for industrial lighting solutions for the
industrial inspection market, including both machine vision and microscopy
industries.

     Lasiris was founded in 1985 to offer technical and scientific expertise in
lasers, optics, and holography. Through a number of research and development
contracts, Lasiris began in 1990 to design a wide range of laser pattern
projectors for industrial inspection and machine vision. Since 1995, Lasiris has
maintained an annual growth rate of approximately 60% and has offered an
expanding range of innovative optics and laser products. Lasiris has
consistently invested a significant percentage of its revenues in research and
development and holds a variety of patents and trademarks. Lasiris operates out
of an approximately 20,000 sq. ft. leased facility in Saint-Laurent, outside
Montreal, Quebec, and employs approximately 50 people. Alain Beauregard,
President of Lasiris, has agreed to join the Company's Board of Directors.

          (a) No indemnification shall be payable pursuant to Section 9.1 above

if on or prior to the Indemnification Cut-Off Date a specific state of facts
shall have become known which may give rise to a claim for indemnification under
Subsection 9.1 and a Buyer Indemnified Party shall have given written notice to
any SPEQ Stockholder Representative of such facts known by such Buyer
Indemnified Party at such time, then the right to indemnification with respect
to such claim shall remain in effect without regard to when such matter shall be
finally determined and disposed of;

          (d) No indemnification shall be payable to a Buyer Indemnified Party
with respect to a claim asserted with respect to any breach of any

respect to such claim against any of Buyer Indemnified Parties;

          (e) The Stockholders shall not have, and shall hereby waive, any right

Parties") harmless from and against any Loss or Losses which may be sustained or
suffered by any of them arising out of or based upon (i) any breach of any
representation, warranty, covenant or agreement made by Buyer in this Agreement
or in any Transaction Document delivered by Buyer hereunder, or by reason of any
claim, action or proceeding asserted or instituted growing out of any matter or
thing constituting such a breach; and (ii) any fraud, intentional
misrepresentation or a deliberate or wilful breach by Buyer of any of their
representations, warranties or covenants under this Agreement, any other
Transaction Document or in any certificate, schedule or exhibit delivered

     9.4 Limitation on Indemnification by Buyer. Notwithstanding the foregoing,
no indemnification shall be payable to the Stockholders with respect to claims
asserted pursuant to Section 9.3 above after the Indemnification Cut-Off Date.
The limitation contained in this Section 9.4 shall not apply to the
indemnification obligations arising under clause (ii) of Section 9.3.

     9.5 Insurance Proceeds. If any claim for which indemnification is sought
hereunder is submitted to and covered by an insurance carrier, the indemnifying
party's or parties' responsibility with respect to such claim shall be net of
any amounts actually paid by such insurance carrier with respect to such insured
claim; provided, however, that such limitation shall only be to the extent that
such amounts are paid without recourse to the indemnified party by way of
deductibles, re-insurance, retro-payments or other risk or loss sharing
arrangement.

     9.6 Notice; Defense of Claims. An indemnified party may make claims for
indemnification hereunder by giving written notice thereof to the indemnifying
party within the period in which indemnification claims can be made hereunder.
If indemnification is sought for a claim or liability asserted by a third party,
the indemnified party shall also give written notice thereof to the indemnifying
party promptly after it receives notice of the claim or liability being
asserted, but the failure to do so shall not relieve the indemnifying party from
any liability except to the extent that it is prejudiced by the failure or delay
in giving such notice. Such notice shall summarize in reasonable detail the
bases for the claim for indemnification, the amount of such claim for
indemnification and, if applicable, any claim or liability being asserted by a
third party. Within 20 days after receiving such notice the indemnifying party
shall give written notice to the indemnified party stating whether it disputes
the claim for indemnification and whether it will defend against any third party
claim or liability at its own cost and expense. If the indemnifying party fails
to give notice that it disputes an indemnification claim within 20 days after
receipt of notice thereof, it shall be deemed to have accepted and agreed to the
claim, which shall become immediately due and payable. The indemnifying party
shall be entitled to direct the defense against a third party claim or liability
with counsel selected by it (subject to the consent of the indemnified party,
which consent shall not be unreasonably withheld) as long as the indemnifying
party is conducting a good faith and diligent defense. The indemnified party
shall at all times have the right to fully participate in the defense of a third
party claim or liability at its own expense directly or through counsel;
provided, however, that if the named parties to the action or proceeding include
both the indemnifying party and the indemnified party and the indemnified party
is advised that representation of both parties by the same counsel would be
inappropriate


                                       38
<PAGE>

Offer of Purchase and Sale


under applicable standards of professional conduct, the indemnified party may
engage separate counsel at the expense of the indemnifying party. If no such
notice of intent to dispute and defend a third party claim or liability is given
by the indemnifying party, or if such good faith and diligent defense is not
being or ceases to be conducted by the indemnifying party, the indemnified party
shall have the right, at the expense of the indemnifying party, to undertake the
defense of such claim or liability (with counsel selected by the indemnified
party), and to compromise or settle it, exercising reasonable business judgment.
If the third party claim or liability is one that by its nature cannot be
defended solely by the indemnifying party, then the indemnified party shall make
available such information and assistance as the indemnifying party may
reasonably request and shall cooperate with the indemnifying party in such
defense, at the expense of the indemnifying party.

     9.7 Satisfaction of Stockholder Indemnification Obligations. In furtherance
of, and without limiting, any right to indemnification with respect to any Buyer
Indemnifiable Claim which Buyer or Canco may have against any Stockholder
hereunder, Buyer or Canco shall be obligated to collect amounts payable to such
party pursuant to this Article 9 (i) first, by the assignment and transfer by
Escrow Agent in accordance with the Escrow Agreement of that number of
Exchangeable Shares exchangeable for shares of Buyer Stock having an aggregate
value (based upon a per share value of $4.875 (U.S.)) equal to such amount
payable, (ii) second, by the assignment and transfer of Exchangeable Shares or
shares of Buyer Stock held by one or more Stockholders having an aggregate value
(based upon a per share value of $4.875 (U.S.)) equal to such amount payable and
(iii) third, by the delivery of cash in an amount equal to such amount payable.
The provisions of this Section 9.7 shall not be deemed to limit in any way
Buyer's or Canco's right to collect any amount due under this Section 9 directly
from any one or more Stockholder.

Meeting and USCO Shareholders Consent, USCO will, or will cause its Transfer
Agent to, mail or cause to be mailed (or otherwise communicate in the same
manner that USCO utilizes in communications to holders of Common Shares) to each
of the Holders named in the List on the same day as the initial mailing or
notice (or other communication) with respect thereto is given by USCO to its

     of Common Shares in connection with each USCO Shareholders Meeting or USCO
     Shareholders Consent.

     For the purpose of determining which Holder is entitled to receive the

Shareholders Consent, the Holders of Exchangeable Shares owned of record by each
Holder shall be determined at the close of business on the record date set by

Holder copies of all proxy materials (including notices of USCO Shareholders
Meetings but excluding proxies to vote Common Shares), information statements,
reports (including without limitation all interim and annual financial
statements) and other written communications that are to be distributed from
time to time to holders of Common Shares at the same time as such materials are
first sent to holders of Common Shares. USCO or the Transfer Agent, as
applicable, will mail or otherwise send to each Holder, at the expense of USCO,
copies of all such materials at the same time as such materials are first sent
to holders of Common Shares.

material sent or given generally to the holders of Common Shares by or on behalf
of a third party, including, without limitation, dissident proxy and information
circulars (and related information and material) and tender and exchange offer
circulars (and related information and material), USCO shall use its

thereof to each Holder as soon as practicable.

     2.4 List of Holders. Canco shall, prior to each annual, general and special
USCO Shareholders Meeting or the seeking of any USCO Shareholders Consent,

the holders of Exchangeable Shares arranged in alphabetical order and showing
the number of Exchangeable Shares held of record by each such Holder, in each
case at the close of business on the date for a USCO Shareholders Meeting or a

established by USCO or pursuant to applicable law for determining the holders of
Common Shares entitled to receive notice of and/or to vote at such USCO
Shareholders Meeting or to give consent in connection with such USCO
Shareholders Consent. Each such List shall be delivered to USCO promptly after
receipt by Canco of USCO's prior notice of the record date for such meeting or
seeking of consent, as the case may be. If there has been no change to the
information contained in the List since the last delivery of such List by Canco
to USCO, Canco shall only be obliged to notify USCO of such fact.

     2.5 Distribution of Written Materials. Any written materials to be
distributed by USCO, the Transfer Agent or Canco, as applicable, to the Holders
pursuant to this Agreement shall be delivered or sent by mail (or otherwise

     dividend on Common Shares;

         (c) take all such actions and do all such things as are necessary or
     desirable to enable and permit Canco, in accordance with Applicable Law, to

into which Common Shares may be reclassified or changed as contemplated by
section 4.7 hereof to be issued and delivered hereunder, including for greater
certainty, pursuant to the Canco Articles, require qualification with or
approval of or the filing of any document or the taking

<PAGE>

                                     - 13 -

of any action with or the obtaining of any order, ruling or consent from any
governmental or regulatory authority under any Canadian or United States
federal, provincial or state law or regulation or pursuant to the rules and
regulations of any regulatory authority or the fulfilment of any other legal
requirement (collectively, the "Applicable Laws") before such shares (or other
shares or securities into which Common Shares may be reclassified or changed as
contemplated by section 4.7 hereof) may be issued and delivered by USCO to the
initial holder thereof, USCO will in good faith expeditiously take all such
commercially reasonable actions and do all such commercially reasonable things
as are necessary to cause such Common Shares (or other shares or securities into
which Common Shares may be reclassified or changed as contemplated by section
4.7 hereof) to take such action or obtain such ruling, order or approval.

     (2) USCO represents and warrants that it has in good faith taken all
actions and done all things as are necessary under Applicable Laws as they exist

section 4.7 hereof) to be issued and delivered hereunder, including for greater
certainty, pursuant to the Canco Articles. USCO covenants and agrees with Canco

nor Canco shall have any obligation to register Common Shares or Exchangeable
Shares under the Securities Act of 1933, as amended, the Securities and Exchange
Act of 1934, as amended, the securities laws of any state of the United States
or any Canadian federal or provincial securities law.

     (3) USCO hereby covenants and agrees with the Stockholders that if, during
the period from and after the first anniversary of the date of this Agreement
and the Stockholders are not entitled to sell Common Shares received in exchange
for Exchangeable Shares in accordance with Rule 144 ("Rule 144") promulgated by
the Securities and Exchange Commission (the "SEC") pursuant to the Securities
Act of 1933, as amended, for any reason whatsoever except for the reason that
the calculation of the holding period required under Rule 144 has been
determined by the SEC to be calculated from the date of the exchange of the
Exchangeable Shares into USCO Shares as opposed to the date of issuance of the
Exchangeable Shares, USCO shall at its own cost and expense file with the SEC a
registration statement (on Form S-1, SB-2, S-3 or such other form as USCO may
deem appropriate) registering such shares for resale. Such registration
statement shall be filed with the SEC not more than sixty (60) days following
the written request of Holders of a majority of the Exchangeable Shares then
outstanding. Notwithstanding the foregoing, it is acknowledged and agreed by the
parties hereto that no Stockholder shall have any right to require

<PAGE>

                                     - 14 -

any such registration if such Stockholder has the ability to sell any Common
Shares held by such party pursuant to Rule 144.

     (1) In the event that USCO shall declare, set a record date for, or give
effect to any issuance or distribution by way of a stock dividend or other
distribution in respect of USCO's issued and outstanding Common Shares of:

         (a) Common Shares (or securities exchangeable for or convertible into
     or carrying rights to acquire Common Shares);

         (b) any options, warrants or other rights entitling the holders of
     Common Shares to subscribe for or to purchase Common Shares (or securities
     exchangeable for or convertible into or carrying rights to acquire Common
     Shares); or

         (c) i) shares or securities of USCO of any class other than Common
     Shares (other than securities exchangeable for or convertible into or
     carrying rights to acquire Common Shares), (ii) options, warrants or rights
     other than those referred to in Section 4.7(1)(b) above, (iii) evidences of
     indebtedness of USCO or (iv) assets of USCO;

USCO shall cause Canco to issue or distribute to and Canco shall simultaneously
issue or distribute to Holders, Class B or Class C shares as per the Canco
Articles or the economic equivalent (determined in accordance with Section
4.7(5) below) on a per share basis of such options, warrants, rights,
securities, evidences of indebtedness or other assets to the Holders determined
as if each such Holder had exchanged all of such Holder's Exchangeable Shares
for Common Shares.

     (2) USCO undertake to do all things as are necessary to enable Canco to
fully satisfy its obligations under paragraphe 4.7(1).

     (3) In the event that at any time during which any Exchangeable Shares

         (a) subdivide, redivide or change the number of then outstanding Common
     Shares into a greater number of Commom Shares;

         (b) reduce, combine or consolidate or change the then outstanding
     Common Shares into a lesser number of Common Shares; or

         (c) reclassify or otherwise change the Common Shares or effect an
     amalgamation, merger, reorganization or other transaction affecting the
     Common Shares;

USCO shall cause Canco to make, or to seek the consent of the Holders to make,
the same or the economically equivalent change to or in the rights of the
Holders of the Exchangeable Shares as per Canco Articles.

     (4) USCO will cause Canco to set the record date for any event referred
to in section 4.7(1) or 4.7(3) above, or (if no record date is applicable for
such event) the effective date for any such event on the same date or dates as
are the record date or the effective date which has been set by USCO with
respect to such event.

     (5) The Canco Board of Directors shall determine, in good faith and in
its sole discretion (with the assistance of such reputable and qualified
independent financial advisors and other experts as the board may require),
economic equivalence for the purposes of any event referred to in section 4.7(1)
or 4.7(3) and each such determination shall be conclusive and binding on Canco
and the Holders. In making each such determination, the following factors shall,
without excluding other factors determined by the board to be relevant, be
considered by the Canco Board of Directors:

         (a) in the case of any stock dividend or other distribution payable in
     Common Shares, the number of such shares issued in proportion to the number
     of Common Shares previously outstanding;

         (b) in the case of the issuance or distribution of any rights, options
     or warrants to subscribe for or purchase Common Shares (or securities
     exchangeable for or convertible into or carrying rights to acquire Common
     Shares), the relationship between the exercise price of each such right,
     option or warrant and the Current Market Value (as determined by the Board
     of Directors in the manner contemplated in the Canco Articles) of a Common
     Share;

         (c) in the case of the issuance or distribution of any other form of
     property (including without limitation any shares or securities of USCO of
     any class other than Common Shares, any rights, options or warrants other
     than those referred to in section 4.7(4)(b) above, any evidences of
     indebtedness of USCO or any assets of

<PAGE>

                                     - 16 -

      USCO, the relationship between the fair market value (as determined by
      the Board of Directors in the manner above contemplated) of such
      property to be issued or distributed with respect to each outstanding
      Common Shares and the Current Market Value (as determined by the Board
      of Directors in the manner above contemplated) of a Common Share; and

         (d) in the case of any subdivision, redivision or change of the then
     outstanding Common Shares into a greater number of Common Shares or the
     reduction, combination or consolidation or change of the then outstanding
     Common Shares into a lesser number of Common Shares or any
     reclassification, amalgamation, merger, reorganization or other transaction
     affecting Common Shares, the effect thereof upon the then outstanding
     Common Shares.

     4.8 Tender Offers, etc. In the event that a tender offer, share exchange
offer, issuer bid, take-over bid or similar transaction with respect to Common
Shares (each, an "Offer") is proposed by USCO or is proposed to USCO or its
shareholders and is recommended by the Board of Directors of USCO, or is
otherwise effected or to be effected with the consent or approval of the Board
of Directors of USCO, USCO will use reasonable efforts (to the extent, in the
case of an Offer by a third party, within its control) expeditiously and in good
faith to take all such actions and do all such things as are reasonably
necessary to enable and permit Holders of Exchangeable Shares to participate in

cooperate with USCO or Canco, as may be required, to facilitate their
participation in such Offer.

will appoint and cause to be appointed proxyholders with respect to all

attending each meeting of Holders of Exchangeable Shares in order to be counted
as part of the quorum for each such meeting. USCO further covenants and agrees
that it will not, and will cause its Subsidiaries or affiliates not to, exercise
any voting rights that may be exercisable by Holders of Exchangeable Shares from
time to time pursuant to the Canco Articles or pursuant to the provisions of the
Business Corporation Act (New Brunswick) (or any successor or other corporate
statute by which Canco may in the future be governed) with respect to any
Exchangeable Shares held by it or by its direct or indirect Subsidiaries or
affiliates in respect of any matter considered at any meeting of Holders of
Exchangeable Shares.

     4.10 Due Performance. On and after the Effective Date, USCO shall, and

rights by any Holder of Exchangeable Shares, under the Canco Articles, and USCO
shall be responsible for the due performance of all of Canco's obligations
hereunder and under the Canco Articles.

     4.11 Issue of Additional Shares. During the term of this Agreement, Canco
will not issue any additional Exchangeable Shares except to the extent required
by any provision hereunder or under the Canco Articles.

     4.12 Books and Records. Each of USCO and Canco shall keep available for
inspection by any Holder, as may be permitted or required by Applicable law, at
their respective principal office, correct and complete books and records of
account relating to their obligations under this Agreement, including, without
limitation, all information relating to mailings and instructions to and from

changed, this Agreement shall forthwith be amended and modified as necessary in
order that it shall apply with full force and effect, mutatis mutandis, to all

and the parties hereto shall execute and deliver a supplemental agreement giving

                              EMPLOYMENT AGREEMENT


     This AGREEMENT (the "Agreement") is made as of May 13, 1998 (the "Effective
Date"), by and among Lasiris, Inc., a Canadian corporation (the "Employer") and
a wholly owned, indirect subsidiary of Stocker & Yale, Inc. ("S&Y"), and Alain
Beauregard (the "Executive").

     WHEREAS, concurrently herewith, Lasiris Holdings, Inc., a Canadian
corporation and a subsidiary of S&Y ("Holding"), is acquiring, directly or
indirectly, all of the issued and outstanding capital stock of the Employer,
pursuant to that certain Offer of Purchase and Sale, dated as of March 14, 1998
(the "Offer"), by and among S&Y, the Employer, and each holder of shares of the
capital stock of the Employer;

     WHEREAS, the Executive has served as President of the Employer from March
1987 until and including the Effective Date;

     WHEREAS, the Employer desires to employ the Executive in connection with,
and to ensure continuity in, the management of the Employer's business and
affairs;

     WHEREAS, the Executive desires to be employed to provide such services;

     WHEREAS, as a result of his prior employment with the Employer and his
continuing employment with the Employer, the Executive has had, and will
continue to have, access to trade secrets and confidential information of the
Employer (including, but not limited to, those trade secrets and confidential
information held by the Employer prior to and as of the Effective Date);

     WHEREAS, the execution and delivery of this Agreement by the Executive is a
condition precedent to the obligation of S&Y and Holding to consummate the
transactions contemplated by the Offer; and

     WHEREAS, in consideration thereof and of his employment and in connection
with his access to such trade secrets and confidential information, the
Executive has also agreed to be bound by certain non-competition,
non-solicitation and non-disclosure provisions.

     NOW THEREFORE, in consideration of the mutual covenants contained herein,
and other good and valuable consideration, the receipt and sufficiency of which
is hereby irrevocably acknowledged, the Employer and the Executive agree as
follows:

     1. Employment. The Employer agrees to employ the Executive and the
Executive agrees to be employed by the Employer on the terms and conditions set
forth in this Agreement.

<PAGE>

     2. Capacity. The Executive shall be employed as President and Chief
Executive Officer, subject to election by the Board of Directors of the Employer
(the "Board of Directors"). The Employer shall take all reasonable means to
cause the election of the Executive to the offices of President and Chief
Executive Officer. In such capacity or capacities, the Executive shall perform
such services and duties in connection with the business, affairs and operations
of the Employer as may be assigned or delegated to the Executive from time to
time by or under the authority of the Board of Directors or the Chief Executive
Officer.

     3. Term. Subject to the provisions of Section 6, the term of employment
pursuant to this Agreement (the "Term") shall expire on the date which is the
third anniversary (the "Third Anniversary") of the date hereof, and shall be
renewed automatically for periods of one (1) year commencing on the Third
Anniversary, and on each subsequent anniversary thereafter, unless either the
Employee or the Employer gives written notice to the other not less than ninety
(90) days prior to the Third Anniversary or any such anniversary of such party's
election not to extend the Term. In the event of any renewal of this Agreement,
the Executive's employment by the Employer shall be on substantially the same
terms as set forth herein, except as may be revised, amended or supplemented by
the mutual agreement of the parties. In the event that (i) the Employer elects
not to renew this Agreement or (ii) the Employer offers to extend the Agreement
on terms and conditions which are not substantially similar to those set forth
herein and, solely as a result thereof, the Executive elects not to renew this
Agreement, the Executive shall be entitled to receive an indemnity (the "Non-
Renewal Payment") in an amount equal to the Executive's annual Salary then in
effect which shall be paid in a single payment on the effective date of the
termination of the Executive. The Executive acknowledges and agrees that in
connection with any such non-renewal the notice provided for in this Section 3
and the payment of the Non-Renewal Payment described herein are reasonable and
adequate in light of the circumstances relating to the execution and delivery of
this Agreement and Executive's employment by the Employer.

     4. Compensation and Benefits. The regular compensation and benefits payable
to the Executive under this Agreement shall be as follows:

         (a) Salary. For all services rendered by the Executive under this
     Agreement, the Employer shall pay the Executive a salary (the "Salary") at
     the annual rate of One Hundred Fifty Thousand Canadian dollars ($150,000
     (CDN)). The Salary shall be payable in periodic installments in accordance
     with the Employer's usual practice for its senior executives.

         (b) Bonus. The Employee shall be entitled to incentive compensation
     pursuant to the terms of the Employer's Incentive Compensation Plan (the
     "Incentive Plan") established by the Board of Directors of S&Y (the "S&Y
     Board"), a copy of which is attached hereto as Exhibit A.

                                        2

<PAGE>

         (c) Regular Benefits. The Executive shall also be entitled to
     participate in any employee benefit plans, medical insurance plans, life
     insurance plans, disability income plans, retirement plans, vacation plans,
     expense reimbursement plans and other benefit plans which the Employer may
     from time to time have in effect for all or most of its senior executives.
     Such participation shall be subject to the terms of the applicable plan
     documents, generally applicable policies of the Employer, applicable law.

         (d) Stock Option Plan. The Executive shall be entitled to participate
     in any stock option or grant plan which S&Y may from time to time have in
     effect for most of all of its senior executives. Such participation shall
     be subject to the terms of the applicable plan documents, generally
     applicable policies of S&Y, applicable law and the discretion of the S&Y
     Board and the Compensation Committee of the S&Y Board. Nothing contained in
     this Agreement shall be construed to create any obligation on the part of
     S&Y to establish any such plan or to maintain the effectiveness of any such
     plan which may be in effect from time to time.

         (e) Other Benefits. The Company shall provide the Executive with or
     reimburse the Executive upon presentation of receipts for (i) the use of an
     automobile (the "Car Allowance"); provided that in no event shall the Car
     Allowance exceed $850.00 (CDN) per month, excluding taxes applicable
     thereto, and (ii) reasonable expenses related thereto.

         (f) Taxation of Payments and Benefits. The Employer shall undertake to
     make deductions, withholdings and tax reports with respect to payments and
     benefits under this Agreement to the extent that it reasonably and in good
     faith believes that it is required to make such deductions, withholdings
     and tax reports. Actual payments to the Executive under this Agreement
     shall be in amounts net of any such deductions or withholdings. Nothing in
     this Agreement shall be construed to require the Employer to make any
     payments to compensate the Executive for any adverse tax effect associated
     with any payments or benefits or for any deduction or withholding from any
     payment or benefit.

         (g) Exclusivity of Salary and Benefits. The Executive shall not be
     entitled to any payments or benefits other than those provided under this
     Agreement or under the Incentive Plan.

     5. Extent of Service. During the Executive's employment under this
Agreement, the Executive shall, subject to the direction and supervision of the
Board of Directors, devote the Executive's full business time, best efforts and
business judgment, skill and knowledge to the advancement of the Employer's
interests and to the discharge of the Executive's duties and responsibilities
under this Agreement. The Executive shall not engage in any other business
activity, except as may be approved by the Board of Directors; provided that
nothing in this Agreement shall be construed as preventing the Executive from:

                                        3

<PAGE>

         (a) investing the Executive's own assets in any company or other entity
     in a manner not prohibited by Section 7(d) and in such form or manner as
     shall not require any material activities on the Executive's part in
     connection with the operations or affairs of the companies or other
     entities in which such investments are made; or

         (b) engaging in religious, charitable or other community or non-profit
     activities that do not impair the Executive's ability to fulfill the
     Executive's duties and responsibilities under this Agreement.

     6. Termination and Termination Benefits. Notwithstanding the provisions of
Section 3, the Executive's employment under this Agreement shall terminate under
the following circumstances set forth in this Section 6.

         (a) Termination by the Employer for Cause. The Executive's employment
     under this Agreement may be terminated for cause without further liability
     on the part of the Employer effective immediately upon a vote of the Board
     of Directors and written notice to the Executive and without further notice
     or indemnity. Only the following shall constitute "cause" for such
     termination:

             (i) dishonest statements or acts of the Executive with respect to
         the Employer or any affiliate of the Employer or any related companies;

             (ii) the Executive shall have been convicted of, or shall plead
         guilty or nolo contendere to, any felony (other than a driving-related
         offense);

             (iii) gross negligence, willful misconduct or insubordination of
         the Executive with respect to the Employer or any affiliate of the
         Employer or any related company; or

             (iv) material breach by the Executive of any of the Executive's
         obligations under this Agreement.

         (b) Termination by the Executive. The Executive's employment under this
     Agreement may be terminated by the Executive by written notice to the Board
     of Directors at least ninety (90) days prior to such termination.

         (c) Termination by the Employer Without Cause. Subject to the payment
     of Termination Benefits pursuant to Section 6(d), the Executive's
     employment under this Agreement may be terminated by the Employer without
     cause upon written notice by a vote of the Board of Directors to the
     Executive. The parties acknowledge and agree that any relocation of the
     Executive away from the greater Montreal area without the Executive's
     consent shall be deemed to be a termination without cause.

                                        4

<PAGE>

         (d) Certain Termination Benefits. Unless otherwise specifically
     provided in this Agreement or otherwise required by law, all compensation
     and benefits payable to the Executive under this Agreement shall terminate
     on the date of termination of the Executive's employment under this
     Agreement. Notwithstanding the foregoing, in the event of termination of
     the Executive's employment with the Employer pursuant to Section 6(c)
     above, the Employer shall provide to the Executive the following
     termination benefits ("Termination Benefits"):

             (i) For the period which is the greater of (x) the remainder of the
         term or (y) twelve (12) months following the Executive's termination
         (the "Indemnity Period"), an indemnity in an amount equal to the Salary
         in effect at the time of the termination of the Executive's employment
         payable in a single payment within five (5) days of such termination;
         and

             (ii) During the Indemnity Period continuation of the medical and
         dental plans in effect at the date of termination of employment,
         excluding long-term disability coverage for any incident occurring
         after his termination of employment; provided, however, that Company
         shall have no obligations under this Section 6(d)(ii) from and after
         the date on which the Executive commences alternative employment.

     Notwithstanding the payment of the indemnity and the continuation of
certain post- termination benefits as provided in this Section 6(d), the parties
hereto acknowledge and agree that the Executive's status as an employee of the
Employer shall terminate on the effective date of any termination pursuant to
this Section 6.

         (e) Disability. If the Executive shall be disabled so as to be unable
     to perform the essential functions of the Executive's then existing
     position or positions under this Agreement with or without reasonable
     accommodation, the Board of Directors may remove the Executive from any
     responsibilities and/or reassign the Executive to another position with the
     Employer. Notwithstanding any such removal or reassignment, the Executive
     shall continue to receive the Executive's full Salary (less any disability
     pay or sick pay benefits to which the Executive may be entitled under the
     Employer's policies) and benefits under Section 4 of this Agreement (except
     to the extent that the Executive may be ineligible for one or more such
     benefits under applicable plan terms) for a period of time which is the
     greater of twelve (12) months or the remainder of the Term. If any question
     shall arise as to whether during any period the Executive is disabled so as
     to be unable to perform the essential functions of the Executive's then
     existing position or positions with or without reasonable accommodation,
     the Executive may, and at the request of the Employer shall, submit to the
     Employer a certification in reasonable detail by a physician mutually
     acceptable to the Employer, on one hand, and the Executive or the
     Executive's guardian, on the other, as to whether the Executive is so
     disabled or how long such disability is expected to continue, and such
     certification shall for the purposes of this Agreement be

                                        5

<PAGE>

         conclusive of the issue. The Executive shall cooperate with any
         reasonable request of the physician in connection with such
         certification. If such question shall arise and the Executive shall
         fail to submit such certification, the Employer's determination of such
         issue shall be binding on the Executive. Subject to the provisions of
         this Section 6(e), the Employer may terminate the employment of the
         Executive upon written notice, approved by the Board of Directors, if
         the Executive becomes physically or mentally disabled to such an extent
         as it makes him unable to perform his duties normally and adequately
         for a period of or periods totaling at least six months during any
         period of twelve consecutive months; provided, that the foregoing shall
         not limit the Executive's right to continue to benefit from such
         applicable short term or long term disability insurance plans in
         accordance with the terms thereof.

     7. Confidential Information, Noncompetition and Cooperation.

         (a) Confidential Information. As used in this Agreement, "Confidential
     Information" means information belonging to the Employer which is of value
     to the Employer in the course of conducting its business and the disclosure
     of which could result in a competitive or other disadvantage to the
     Employer. Confidential Information includes, without limitation, financial
     information, reports, and forecasts; inventions, improvements and other
     intellectual property; trade secrets; know-how; designs, processes or
     formulae; software; market or sales information or plans; customer lists;
     business plans; and possible acquisitions or dispositions of businesses or
     facilities which have been discussed or considered by the management of the
     Employer. Confidential Information includes information developed by the
     Executive in the course of the Executive's employment by the Employer, as
     well as other information to which the Executive may have access in
     connection with the Executive's employment. Confidential Information also
     includes the confidential information of others with which the Employer has
     a business relationship. Notwithstanding the foregoing, Confidential
     Information does not include information in the public domain, unless due
     to breach of the Executive's duties under Section 7(b).

         (b) Confidentiality. The Executive understands and agrees that the
     Executive's employment creates a relationship of confidence and trust
     between the Executive and the Employer with respect to all Confidential
     Information. At all times, both during the Executive's employment with the
     Employer and for a period which shall be the greater of (i) five (5) years
     or (ii) such period as the Confidential Information may reasonably be
     deemed to be of value to the Employer or any of its affiliates after his
     termination, the Executive will keep in confidence and trust all such
     Confidential Information, and will not use or disclose any such
     Confidential Information without the written consent of the Employer,
     except as may be necessary in the ordinary course of performing the
     Executive's duties to the Employer.

         (c) Documents, Records, etc. All documents, records, data, apparatus,
     equipment and other physical property, whether or not pertaining to
     Confidential

                                        6

<PAGE>

     Information, which are furnished to the Executive by the Employer or
     are produced by the Executive in connection with the Executive's employment
     will be and remain the sole property of the Employer. The Executive will
     return to the Employer all such materials and property as and when
     requested by the Employer. In any event, the Executive will return all such
     materials and property immediately upon termination of the Executive's
     employment for any reason. The Executive will not retain with the Executive
     any such material or property or any copies thereof after such termination.

         (d) Noncompetition. During the Term and for one (1) year thereafter,
     the Executive will not, directly or indirectly, whether as owner, partner,
     shareholder, consultant, agent, employee, co-venturer or otherwise, engage,
     participate, assist or invest in any Competing Business (as hereinafter
     defined). The Executive acknowledges that the restrictions set forth in
     this Section 7(d) are necessary to protect the Employer's legitimate
     interest in its Confidential Information and established employee, customer
     and supplier relationships and goodwill, and agrees that such restrictions
     are reasonable and appropriate for this purpose. For purposes of this
     Agreement, the term "Competing Business" shall mean a business conducted
     anywhere in the United States of America which is substantially similar to
     and competitive with the industrial lighting, lasers for machine vision or
     phase masks business which the Employer or any of its affiliates conducts
     at the time the employment of the Executive is terminated.

         (e) Nonsolicitation. During the Term and for two (2) years thereafter,
     the Executive will not, directly or indirectly, whether as owner, partner,
     shareholder, consultant, agent, employee, co-venturer, or otherwise (i)
     employ, attempt to employ, recruit or otherwise solicit, induce or
     influence any person to leave employment with the Employer (other than
     terminations of employment of subordinate employees undertaken in the
     course of the Executive's employment with the Employer); or (ii) solicit or
     encourage or permit the use of the Executive's name to solicit or encourage
     any customer or supplier to terminate or otherwise modify adversely its
     business relationship with the Employer.

     8.  Ownership of Inventions, Files and Other Property.

         (a) The Executive hereby assigns and agrees to the Employer all his
     rights in inventions, discoveries, developments, improvements and ideas
     (the "Covered Property") made or designed by him or that may be made or
     designed by him for the duration of his employment, whether alone or
     jointly with other persons, using the equipment or facilities of the
     Employer or within a period of one (1) year following the termination of
     his employment, if such Covered Property results from or arises out of any
     work performed by the Executive on behalf of the Employer and are connected
     with any matter relating to any goods, products or services manufactured,
     assembled, distributed, sold, in development or otherwise provided by the
     Employer or any of its

                                        7

<PAGE>

     affiliates as the business of such entities is conducted as of the date
     of the termination of the Executive's employment by the Employer.

         (b) The Executive shall make full and prompt disclosure to the Employer
     of all Covered Property covered by this Section 8 and shall not disclose to
     any other person any related information without obtaining the prior
     written authorization of the Employer.

         (c) At any time for the duration of his employment or after the
     termination of his employment, the Executive shall sign, acknowledge and
     deliver, at the Employer's expense, but without other compensation than a
     reasonable sum for the time he devotes thereto if his employment has then
     terminated, any document, including applications for patents and for
     assignment of all interests related thereto or related to the Covered
     Property referred to in this Section 8, as required to enable the Employer
     to publish or protect such Covered Property by patents or otherwise in one
     country or in all countries, and shall assign to the Employer the ownership
     of such Covered Property. The Executive hereunder shall also give any other
     assistance as the Employer may require with respect to any proceeding or
     litigation before the Patent Office of Canada or the Patent and Trademark
     Office in the United States of America relating to such Covered Property.
     The Employer shall reimburse the Executive for (i) any reasonable
     out-of-pocket expenses and (ii) any loss of salary actually incurred in
     connection with the Executive's performance of obligations pursuant to this
     Section 8(c); provided that any payment in respect of loss salary shall be
     paid at a per diem rate not in excess of the highest salary paid
     (calculated on a per diem basis) to the Executive during the Term of this
     Agreement or any renewal thereof.

         (d) The full list of Covered Property, whether or not patented, made,
     designed or invented by the Executive previous to his employment hereunder
     is attached to this agreement. In the absence of such a list, the Executive
     declares and certifies that he has not made, designed or invented any
     Covered Property previous to his employment.

         (e) Any file, sketch, drawing, letter, report, memo or other document,
     any equipment, machinery, tool, instrument or other device, any diskette,
     recording tape, compact disc or other property relating in any way to the
     business or operation of the Employer or any of its affiliates which comes
     into the Executive's possession during his employment by the Employer, in
     the performance or in the course of his work, regardless of whether he has
     participated in its preparation or design, how it may have come into his
     possession and whether or not it is an original or a copy, shall at all
     times remain the property of the Employer and, upon the termination of the
     Executive's employment, shall not be removed from the Employer's premises
     but shall be returned to the Employer or its designated representative
     before the Executive leaves his place of work.

     9. Third-Party Agreements and Rights. The Executive hereby confirms that
the Executive is not bound by the terms of any agreement with any previous
employer or other party which restricts in any way the Executive's use or
disclosure of information or the Executive's engagement in any business. The
Executive represents to the Employer that the Executive's execution of this
Agreement, the Executive's employment with the Employer and the performance of
the Executive's proposed duties for the Employer will not violate any
obligations the Executive may have to any such previous employer or other party.
In the Executive's work for the Employer, the Executive will not disclose or
make use of any information in violation of any agreements with or rights of any
such previous employer or other party, and the Executive will not bring to the
premises of the Employer any copies or other tangible embodiments of non-public
information belonging to or obtained from any such previous employment or other
party.

     10. Litigation and Regulatory Cooperation. During and after the Executive's
employment, the Executive shall cooperate fully with the Employer in the defense
or prosecution of any claims or actions now in existence or which may be brought
in the future against or on behalf of the Employer which relate to events or
occurrences that transpired while the Executive was employed by the Employer.
The Executive's full cooperation in connection with such claims or actions shall
include, but not be limited to, being available to meet with counsel to prepare
for discovery or trial and to act as a witness on behalf of the Employer at
mutually convenient times. During and after the Executive's employment, the
Executive also shall cooperate fully with the Employer in connection with any
investigation or review of any federal, state or local regulatory authority as
any such investigation or review relates to events or occurrences that
transpired while the Executive was employed by the Employer. The Employer shall
reimburse the Executive for (i) any reasonable out-of-pocket expenses and (ii)
any loss of salary actually incurred in connection with the Executive's
performance of obligations pursuant to this Section 10; provided that any
payment in respect of loss salary shall be paid at a per diem rate not in excess
of the highest salary paid (calculated on a per diem basis) to the Executive
during the Term of this Agreement or any renewal thereof.

     11. Injunction. The Executive agrees that it could be difficult to measure
any damages caused to the Employer which might result from any breach by the
Executive of the agreements set forth in Section 7 or Section 8 hereof, and that
in any event money damages could be an inadequate remedy for any such breach.

     12. Consent to Jurisdiction. The parties hereby agree that the court having
jurisdiction in any action or procedure regarding the application,
interpretation, execution and enforcement of the present Agreement shall be
under the jurisdiction of the Court of the Province of Quebec in the judicial
district of Montreal.

     13. Integration. This Agreement, including the preamble hereto, constitutes
the entire agreement between the parties with respect to the subject matter
hereof and supersedes all prior agreements between the parties with respect to
any related subject matter. The terms

                                        9

<PAGE>

of the present Agreement resolve and cancel any prior agreement, verbal or
written with respect to the Executive's employment, each of the parties granting
the other full and final release and discharge from any action, cause of action,
claim or demand of any nature based on or arising out of the terms or provisions
of any prior agreement.

     14. Assignment; Successors and Assigns, etc. Neither the Employer nor the
Executive may make any assignment of this Agreement or any interest herein, by
operation of law or otherwise, without the prior written consent of the other
party; provided that the Employer may assign its rights under this Agreement
without the consent of the Executive in the event that the Employer shall effect
a reorganization, consolidate with or merge into any other corporation,
partnership, organization or other entity, or transfer all or substantially all
of its properties or assets to any other corporation, partnership, organization
or other entity. This Agreement shall inure to the benefit of and be binding
upon the Employer and the Executive, their respective successors, executors,
administrators, heirs and permitted assigns.

     15. Enforceability. If any portion or provision of this Agreement
(including, without limitation, any portion or provision of any section of this
Agreement) shall to any extent be declared illegal or unenforceable by a court
of competent jurisdiction, then the remainder of this Agreement, or the
application of such portion or provision in circumstances other than those as to
which it is so declared illegal or unenforceable, shall not be affected thereby,
and each portion and provision of this Agreement shall be valid and enforceable
to the fullest extent permitted by law.

     16. Waiver. No waiver or modification of any provision hereof shall be
effective unless made in writing and signed by the waiving party. The failure of
any party to require the performance of any term or obligation of this
Agreement, or the waiver by any party of any breach of this Agreement, shall not
prevent any subsequent enforcement of such term or obligation or be deemed a
waiver of any subsequent breach.

     17. Notices. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by a nationally recognized overnight courier service or by

                              EMPLOYMENT AGREEMENT


     This AGREEMENT (the "Agreement") is made as of May 13, 1998 (the "Effective
Date"), by and among Lasiris, Inc., a Canadian corporation (the "Employer") and
a wholly owned, indirect subsidiary of Stocker & Yale, Inc. ("S&Y"), and Luc
Many (the "Executive").

     WHEREAS, concurrently herewith, Lasiris Holdings, Inc., a New Brunswick
corporation and a subsidiary of S&Y ("Holding"), is acquiring, directly or
indirectly, all of the issued and outstanding capital stock of the Employer,
pursuant to that certain Offer of Purchase and Sale, dated as of March 14, 1998
(the "Offer"), by and among S&Y, the Employer, and each holder of shares of the
capital stock of the Employer;

     WHEREAS, the Executive has served as General Manager of the Employer from
April 1987 until and including the Effective Date;

     WHEREAS, the Employer desires to employ the Executive in connection with,
and to ensure continuity in, the management of the Employer's business and
affairs;

     WHEREAS, the Executive desires to be employed to provide such services;

     WHEREAS, as a result of his prior employment with the Employer and his
continuing employment with the Employer, the Executive has had, and will
continue to have, access to trade secrets and confidential information of the
Employer (including, but not limited to, those trade secrets and confidential
information held by the Employer prior to and as of the Effective Date);

     WHEREAS, the execution and delivery of this Agreement by the Executive is a
condition precedent to the obligation of S&Y and Holding to consummate the
transactions contemplated by the Offer; and

     WHEREAS, in consideration thereof and of his employment and in connection
with his access to such trade secrets and confidential information, the
Executive has also agreed to be bound by certain non-competition,
non-solicitation and non-disclosure provisions.

     NOW THEREFORE, in consideration of the mutual covenants contained herein,
and other good and valuable consideration, the receipt and sufficiency of which
is hereby irrevocably acknowledged, the Employer and the Executive agree as
follows:

     1. Employment. The Employer agrees to employ the Executive and the
Executive agrees to be employed by the Employer on the terms and conditions set
forth in this Agreement.

<PAGE>

     2. Capacity. The Executive shall be employed as Executive Vice President
and General Manager, subject to election by the Board of Directors of the
Employer (the "Board of Directors"). The Employer shall take all reasonable
means to cause the election of the Executive to the office of Executive Vice
President and General Manager. In such capacity or capacities, the Executive
shall perform such services and duties in connection with the business, affairs
and operations of the Employer as may be assigned or delegated to the Executive
from time to time by or under the authority of the Board of Directors or the
President and Chief Executive Officer.

     3. Term. Subject to the provisions of Section 6, the term of employment
pursuant to this Agreement (the "Term") shall expire on the date which is the
third anniversary (the "Third Anniversary") of the date hereof, and shall be
renewed automatically for periods of one (1) year commencing on the Third
Anniversary, and on each subsequent anniversary thereafter, unless either the
Employee or the Employer gives written notice to the other not less than ninety
(90) days prior to the Third Anniversary or any such anniversary of such party's
election not to extend the Term. In the event of any renewal of this Agreement,
the Executive's employment by the Employer shall be on substantially the same
terms as set forth herein, except as may be revised, amended or supplemented by
the mutual agreement of the parties. In the event that (i) the Employer elects
not to renew this Agreement or (ii) the Employer offers to extend the Agreement
on terms and conditions which are not substantially similar to those set forth
herein and, solely as a result thereof, the Executive elects not to renew this
Agreement, the Executive shall be entitled to receive an indemnity (the "Non-
Renewal Payment") in an amount equal to the Executive's annual Salary then in
effect which shall be paid in a single payment on the effective date of the
termination of the Executive. The Executive acknowledges and agrees that in
connection with any such non-renewal the notice provided for in this Section 3
and the payment of the Non-Renewal Payment described herein are reasonable and
adequate in light of the circumstances relating to the execution and delivery of
this Agreement and Executive's employment by the Employer.

     4. Compensation and Benefits. The regular compensation and benefits payable
to the Executive under this Agreement shall be as follows:

         (a) Salary. For all services rendered by the Executive under this
     Agreement, the Employer shall pay the Executive a salary (the "Salary") at
     the annual rate of One Hundred Fifty Thousand Canadian dollars ($150,000
     (CDN)). The Salary shall be payable in periodic installments in accordance
     with the Employer's usual practice for its senior executives.

         (b) Bonus. The Employee shall be entitled to incentive compensation
     pursuant to the terms of the Employer's Incentive Compensation Plan (the
     "Incentive Plan") established by the Board of Directors of S&Y (the "S&Y
     Board"), a copy of which is attached hereto as Exhibit A.

                                        2

<PAGE>

         (c) Regular Benefits. The Executive shall also be entitled to
     participate in any employee benefit plans, medical insurance plans, life
     insurance plans, disability income plans, retirement plans, vacation plans,
     expense reimbursement plans and other benefit plans which the Employer may
     from time to time have in effect for all or most of its senior executives.
     Such participation shall be subject to the terms of the applicable plan
     documents, generally applicable policies of the Employer, applicable law.

         (d) Stock Option Plan. The Executive shall be entitled to participate
     in any stock option or grant plan which S&Y may from time to time have in
     effect for most of all of its senior executives. Such participation shall
     be subject to the terms of the applicable plan documents, generally
     applicable policies of S&Y, applicable law and the discretion of the S&Y
     Board and the Compensation Committee of the S&Y Board. Nothing contained in
     this Agreement shall be construed to create any obligation on the part of
     S&Y to establish any such plan or to maintain the effectiveness of any such
     plan which may be in effect from time to time.

         (e) Taxation of Payments and Benefits. The Employer shall undertake to
     make deductions, withholdings and tax reports with respect to payments and
     benefits under this Agreement to the extent that it reasonably and in good
     faith believes that it is required to make such deductions, withholdings
     and tax reports. Actual payments to the Executive under this Agreement
     shall be in amounts net of any such deductions or withholdings. Nothing in
     this Agreement shall be construed to require the Employer to make any
     payments to compensate the Executive for any adverse tax effect associated
     with any payments or benefits or for any deduction or withholding from any
     payment or benefit.

         (f) Exclusivity of Salary and Benefits. The Executive shall not be
     entitled to any payments or benefits other than those provided under this
     Agreement or under the Incentive Plan.

     5. Extent of Service. During the Executive's employment under this
Agreement, the Executive shall, subject to the direction and supervision of the
Board of Directors and the Employer's President and Chief Executive Officer,
devote the Executive's full business time, best efforts and business judgment,
skill and knowledge to the advancement of the Employer's interests and to the
discharge of the Executive's duties and responsibilities under this Agreement.
The Executive shall not engage in any other business activity, except as may be
approved by the Board of Directors; provided that nothing in this Agreement
shall be construed as preventing the Executive from:

         (a) investing the Executive's own assets in any company or other entity
     in a manner not prohibited by Section 7(d) and in such form or manner as
     shall not require any material activities on the Executive's part in
     connection with the operations or affairs of the companies or other
     entities in which such investments are made; or

                                        3

<PAGE>

         (b) engaging in religious, charitable or other community or non-profit
     activities that do not impair the Executive's ability to fulfill the
     Executive's duties and responsibilities under this Agreement.

     6. Termination and Termination Benefits. Notwithstanding the provisions of
Section 3, the Executive's employment under this Agreement shall terminate under
the following circumstances set forth in this Section 6.

         (a) Termination by the Employer for Cause. The Executive's employment
     under this Agreement may be terminated for cause without further liability
     on the part of the Employer effective immediately upon a vote of the Board
     of Directors and written notice to the Executive and without further notice
     or indemnity. Only the following shall constitute "cause" for such
     termination:

             (i) dishonest statements or acts of the Executive with respect to
         the Employer or any affiliate of the Employer or any related companies;

             (ii) Executive shall have been convicted of, or shall plead guilty
         or nolo contendere to, any felony (other than a driving-related
         offense);

             (iii) gross negligence, willful misconduct or insubordination of
         the Executive with respect to the Employer or any affiliate of the
         Employer or any related company; or

             (iv) material breach by the Executive of any of the Executive's
         obligations under this Agreement.

         (b) Termination by the Executive. The Executive's employment under this
     Agreement may be terminated by the Executive by written notice to the Board
     of Directors at least ninety (90) days prior to such termination.

         (c) Termination by the Employer Without Cause. Subject to the payment
     of Termination Benefits pursuant to Section 6(d), the Executive's
     employment under this Agreement may be terminated by the Employer without
     cause upon written notice by a vote of the Board of Directors to the
     Executive. The parties acknowledge and agree that any relocation of the
     Executive away from the greater Montreal area without the Executive's
     consent shall be deemed to be a termination without cause.

         (d) Certain Termination Benefits. Unless otherwise specifically
     provided in this Agreement or otherwise required by law, all compensation
     and benefits payable to the Executive under this Agreement shall terminate
     on the date of termination of the Executive's employment under this
     Agreement. Notwithstanding the foregoing, in the event of termination of
     the Executive's employment with the Employer pursuant to

                                        4

<PAGE>



      Section 6(c) above, the Employer shall provide to the Executive the
      following termination benefits ("Termination Benefits"):

             (i) For the period which is the greater of (x) the remainder of the
         term or (y) twelve (12) months following the Executive's termination
         (the "Indemnity Period"), an indemnity in an amount equal to the Salary
         in effect at the time of the termination of the Executive's employment
         payable in a single payment within five (5) days of such termination;

             (ii) During the Indemnity Period continuation of the medical and
         dental plans in effect at the date of termination of employment,
         excluding long-term disability coverage for any incident occurring
         after his termination of employment; provided, however, that Company
         shall have no obligations under this Section 6(d)(ii) from and after
         the date on which the Executive commences alternative employment; and

             (iii) For a period not to exceed twelve (12) months, following
         termination of the Executive's employment by Employer, the Employer
         shall provide career consulting services to the Executive; provided
         that the Employer shall not be required to incur costs or expenses in
         excess of $7,500 (CDN) in connection with such career consulting
         services.

         Notwithstanding the payment of the indemnity and the continuation of
     certain post-termination benefits as provided in this Section 6(d), the
     parties hereto acknowledge and agree that the Executive's status as an
     employee of the Employer shall terminate on the effective date of any
     termination pursuant to this Section 6.

         (e) Disability. If the Executive shall be disabled so as to be unable
     to perform the essential functions of the Executive's then existing
     position or positions under this Agreement with or without reasonable
     accommodation, the Board of Directors may remove the Executive from any
     responsibilities and/or reassign the Executive to another position with the
     Employer. Notwithstanding any such removal or reassignment, the Executive
     shall continue to receive the Executive's full Salary (less any disability
     pay or sick pay benefits to which the Executive may be entitled under the
     Employer's policies) and benefits under Section 4 of this Agreement (except
     to the extent that the Executive may be ineligible for one or more such
     benefits under applicable plan terms) for a period of time which is the
     greater of twelve (12) months or the remainder of the Term. If any question
     shall arise as to whether during any period the Executive is disabled so as
     to be unable to perform the essential functions of the Executive's then
     existing position or positions with or without reasonable accommodation,
     the Executive may, and at the request of the Employer shall, submit to the
     Employer a certification in reasonable detail by a physician mutually
     acceptable to the Employer, on one hand, and the Executive or the
     Executive's guardian, on the other as to whether the Executive is so
     disabled or how long such disability is expected to

                                        5

<PAGE>

     continue, and such certification shall for the purposes of this Agreement
     be conclusive of the issue. The Executive shall cooperate with any
     reasonable request of the physician in connection with such certification.
     If such question shall arise and the Executive shall fail to submit such
     certification, the Employer's determination of such issue shall be binding
     on the Executive. Subject to the provisions of this Section 6(e), the
     Employer may terminate the employment of the Executive upon written notice,
     approved by the Board of Directors, if the Executive becomes physically or
     mentally disabled to such an extent as it makes him unable to perform his
     duties normally and adequately for a period of or periods totaling at least
     six months during any period of twelve consecutive months; provided, that
     the foregoing shall not limit the Executive's right to continue to benefit
     from such applicable short term or long term disability insurance plans in
     accordance with the terms thereof.

     7. Confidential Information, Noncompetition and Cooperation.

         (a) Confidential Information. As used in this Agreement, "Confidential
     Information" means information belonging to the Employer which is of value
     to the Employer in the course of conducting its business and the disclosure
     of which could result in a competitive or other disadvantage to the
     Employer. Confidential Information includes, without limitation, financial
     information, reports, and forecasts; inventions, improvements and other
     intellectual property; trade secrets; know-how; designs, processes or
     formulae; software; market or sales information or plans; customer lists;
     business plans; and possible acquisitions or dispositions of businesses or
     facilities which have been discussed or considered by the management of the
     Employer. Confidential Information includes information developed by the
     Executive in the course of the Executive's employment by the Employer, as
     well as other information to which the Executive may have access in
     connection with the Executive's employment. Confidential Information also
     includes the confidential information of others with which the Employer has
     a business relationship. Notwithstanding the foregoing, Confidential
     Information does not include information in the public domain, unless due
     to breach of the Executive's duties under Section 7(b).

         (b) Confidentiality. The Executive understands and agrees that the
     Executive's employment creates a relationship of confidence and trust
     between the Executive and the Employer with respect to all Confidential
     Information. At all times, both during the Executive's employment with the
     Employer and for a period which shall be the greater of (i) five (5) years
     or (ii) such period as the Confidential Information may reasonably be
     deemed to be of value to the Employer or any of its affiliates after his
     termination, the Executive will keep in confidence and trust all such
     Confidential Information, and will not use or disclose any such
     Confidential Information without the written consent of the Employer,
     except as may be necessary in the ordinary course of performing the
     Executive's duties to the Employer.

                                        6

<PAGE>

         (c) Documents, Records, etc. All documents, records, data, apparatus,
     equipment and other physical property, whether or not pertaining to
     Confidential Information, which are furnished to the Executive by the
     Employer or are produced by the Executive in connection with the
     Executive's employment will be and remain the sole property of the
     Employer. The Executive will return to the Employer all such materials and
     property as and when requested by the Employer. In any event, the Executive
     will return all such materials and property immediately upon termination of
     the Executive's employment for any reason. The Executive will not retain
     with the Executive any such material or property or any copies thereof
     after such termination.

         (d) Noncompetition. During the Term and for one (1) year thereafter,
     the Executive will not, directly or indirectly, whether as owner, partner,
     shareholder, consultant, agent, employee, co-venturer or otherwise, engage,
     participate, assist or invest in any Competing Business (as hereinafter
     defined). The Executive acknowledges that the restrictions set forth in
     this Section 7(d) are necessary to protect the Employer's legitimate
     interest in its Confidential Information and established employee, customer
     and supplier relationships and goodwill, and agrees that such restrictions
     are reasonable and appropriate for this purpose. For purposes of this
     Agreement, the term "Competing Business" shall mean a business conducted
     anywhere in the United States of America which is substantially similar to
     and competitive with the industrial lighting, lasers for machine vision or
     phase masks business which the Employer or any of its affiliates conducts
     at the time the employment of the Executive is terminated.

         (e) Nonsolicitation. During the Term and for two (2) years thereafter,
     the Executive will not, directly or indirectly, whether as owner, partner,
     shareholder, consultant, agent, employee, co-venturer, or otherwise (i)
     employ, attempt to employ, recruit or otherwise solicit, induce or
     influence any person to leave employment with the Employer (other than

     jointly with other persons, using the equipment or facilities of the
     Employer or within a period of one (1) year following the termination of

     work performed by the Executive on behalf of the Employer and are connected
     with any matter relating to any goods, products or services manufactured,
     assembled,

     Employer.

         (b) The Executive shall make full and prompt disclosure to the Employer
     of all Covered Property covered by this Section 8 and shall not disclose to
     any other person any related information without obtaining the prior
     written authorization of the Employer.

         (c) At any time for the duration of his employment or after the
     termination of his employment, the Executive shall sign, acknowledge and
     deliver, at the Employer's expense, but without other compensation than a

     terminated, any document, including applications for patents and for
     assignment of all interests related thereto or related to the Covered
     Property referred to in this Section 8, as required to enable the Employer
     to publish or protect such Covered Property by patents or otherwise in one

     The Employer shall reimburse the Executive for (i) any reasonable
     out-of-pocket expenses and (ii) any loss of salary actually incurred in
     connection with the Executive's performance of obligations pursuant to this
     Section 8(c); provided that any payment in respect of loss salary shall be
     paid at a per diem rate not in excess of the highest salary paid
     (calculated on a per diem basis) to the Executive during the Term of this
     Agreement or any renewal thereof.

         (d) The full list of Covered Property, whether or not patented, made,
     designed or invented by the Executive previous to his employment hereunder
     is attached to this agreement. In the absence of such a list, the Executive

     business or operation of the Employer or any of its affiliates which comes
     into the Executive's possession during his employment by the Employer, in
     the performance or in the course of his work, regardless of whether he has
     participated in its preparation or design, how it may have come into his
     possession and whether or not it is an original or a copy, shall at all
     times remain the property of the Employer and, upon the termination of the
     Executive's employment, shall not be removed from the Employer's premises
     but shall be returned to the Employer or its designated representative
     before the Executive leaves his place of work.

     9. Third-Party Agreements and Rights. The Executive hereby confirms that
the Executive is not bound by the terms of any agreement with any previous
employer or other party which restricts in any way the Executive's use or
disclosure of information or the Executive's engagement in any business. The
Executive represents to the Employer that the Executive's execution of this
Agreement, the Executive's employment with the Employer and the performance of
the Executive's proposed duties for the Employer will not violate any
obligations the Executive may have to any such previous employer or other party.
In the Executive's work for the Employer, the Executive will not disclose or
make use of any information in violation of any agreements with or rights of any
such previous employer or other party, and the Executive will not bring to the
premises of the Employer any copies or other tangible embodiments of non-public
information belonging to or obtained from any such previous employment or other
party.

     10. Litigation and Regulatory Cooperation. During and after the Executive's
employment, the Executive shall cooperate fully with the Employer in the defense
or prosecution of any claims or actions now in existence or which may be brought
in the future against or on behalf of the Employer which relate to events or
occurrences that transpired while the Executive was employed by the Employer.
The Executive's full cooperation in connection with such claims or actions shall
include, but not be limited to, being available to meet with counsel to prepare
for discovery or trial and to act as a witness on behalf of the Employer at
mutually convenient times. During and after the Executive's employment, the
Executive also shall cooperate fully with the Employer in connection with any
investigation or review of any federal, state or local regulatory authority as
any such investigation or review relates to events or occurrences that
transpired while the Executive was employed by the Employer. The Employer shall
reimburse the Executive for (i) any reasonable out-of-pocket expenses and (ii)
any loss of salary actually incurred in connection with the Executive's
performance of obligations pursuant to this Section 10; provided that any
payment in respect of loss salary shall be paid at a per diem rate not in excess
of the highest salary paid (calculated on a per diem basis) to the Executive
during the Term of this Agreement or any renewal thereof.

     11. Injunction. The Executive agrees that it could be difficult to measure
any damages caused to the Employer which might result from any breach by the
Executive of the agreements set forth in Section 7 or Section 8 hereof, and that
in any event money damages could be an inadequate remedy for any such breach.

     12. Consent to Jurisdiction. The parties hereby agree that the court having
jurisdiction in any action or procedure regarding the application,
interpretation, execution and enforcement of the present Agreement shall be
under the jurisdiction of the Court of the Province of Quebec in the judicial
district of Montreal.

     13. Integration. This Agreement, including the preamble hereto, constitutes
the entire agreement between the parties with respect to the subject matter
hereof and supersedes all prior agreements between the parties with respect to
any related subject matter. The terms

                                        9

<PAGE>

of the present Agreement resolve and cancel any prior agreement, verbal or
written with respect to the Executive's employment, each of the parties granting
the other full and final release and discharge from any action, cause of action,
claim or demand of any nature based on or arising out of the terms or provisions
of any prior agreement.

     14. Assignment; Successors and Assigns, etc. Neither the Employer nor the
Executive may make any assignment of this Agreement or any interest herein, by
operation of law or otherwise, without the prior written consent of the other
party; provided that the Employer may assign its rights under this Agreement
without the consent of the Executive in the event that the Employer shall effect
a reorganization, consolidate with or merge into any other corporation,
partnership, organization or other entity, or transfer all or substantially all
of its properties or assets to any other corporation, partnership, organization
or other entity. This Agreement shall inure to the benefit of and be binding
upon the Employer and the Executive, their respective successors, executors,
administrators, heirs and permitted assigns.

     15. Enforceability. If any portion or provision of this Agreement
(including, without limitation, any portion or provision of any section of this
Agreement) shall to any extent be declared illegal or unenforceable by a court
of competent jurisdiction, then the remainder of this Agreement, or the
application of such portion or provision in circumstances other than those as to
which it is so declared illegal or unenforceable, shall not be affected thereby,
and each portion and provision of this Agreement shall be valid and enforceable
to the fullest extent permitted by law.

     16. Waiver. No waiver or modification of any provision hereof shall be
effective unless made in writing and signed by the waiving party. The failure of
any party to require the performance of any term or obligation of this
Agreement, or the waiver by any party of any breach of this Agreement, shall not
prevent any subsequent enforcement of such term or obligation or be deemed a
waiver of any subsequent breach.

provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by a nationally recognized overnight courier service or by

                                  LASIRIS, INC.
                      EXECUTIVE INCENTIVE COMPENSATION PLAN

     Canada) applied consistently (the "Audited Financial Statements").

          (b) The aggregate amount of cash to be awarded under the Plan with
     respect to each Fiscal Year (the "Aggregate Award Amount") shall be
     determined based on the earnings before interest, taxes, depreciation and
     amortization ("EBITDA") reflected on the Audited Financial Statements and

     Societe de Development du Quebec ("SDI") pursuant to that certain letter

     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
<PAGE>



     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
<PAGE>


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.

     11.  Language

     At the request of the parties, this agreement and all documents relating
thereto have been, and shall be, drawn up in the English language. A la demande
des parties aux presentes, cette convention et tout dcument s'y rapportant ont
