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.
