                          NOTES TO FINANCIAL STATEMENTS

NOTE 1.  GENERAL

         The interim consolidated financial statements presented have been
prepared by Stocker & Yale, Inc. (the "Company") without audit and, in the
opinion of the management, reflect all adjustments of a normal recurring nature
necessary for a fair statement of (a) the results of operations for the three
month and six month periods ended June 30,1998 and June 30,1997 (b) the
financial position at June 30,1998 and (c) the cash flows for the six month
periods ended June 30,1998 and June 30,1997. Interim results are not necessarily
indicative of results for a full year.

         The consolidated balance sheet presented as of December 31,1997 has
been derived from the consolidated financial statements that have been audited
by the Company's independent public accountants. The consolidated financial
statements and notes are condensed as permitted by Form 10-QSB and do not
contain certain information included in the annual financial statements and
notes of the Company. The consolidated financial statements and notes included
herein should be read in conjunction with the financial statements and notes
included in the Company's Annual Report on Form 10-KSB.

NOTE 2.  ACQUISITION OF LASIRIS AND PURCHASE PRICE ALLOCATION

Overview

         On May 13, 1998, Stocker & Yale, Inc. (the "Company") acquired Lasiris,
Inc. ("Lasiris"), 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"). Lasiris will be operated as a wholly-owned
Canadian subsidiary.

         In connection with the acquisition, the stockholders of Lasiris
received an aggregate of approximately $3.2 million in cash and 444,146 shares
of LHI's capital stock which are exchangeable for shares of the Company's common
stock on a one for one basis. 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 of $3.50 per share; (ii) a loan in the amount of
$750,000 from a bank which is secured by a second mortgage interest in the
Company's headquarters; (iii) a loan of approximately $800,000 pursuant to a
credit agreement between the Toronto Dominion Bank and Lasiris; and (iv) cash in
the amount of $950,000 received pursuant to the prepayment of a note receivable
due to the Company.

ALLOCATION OF PURCHASE PRICE

         The acquisition was accounted for as a purchase, and accordingly, the
initial purchase price and acquisition costs aggregating approximately $5.5
million have preliminarily been allocated to the assets acquired, which consist
of approximately $4.0 million in identifiable assets, approximately $0.4 million
in goodwill, and approximately $1.1 million of in-process research and
development which was charged to operations in the second quarter of 1998.
The purchase price allocations represent the fair values determined by an
independent appraisal.

         The following outlines the allocation of purchase price for the
acquisition of Lasiris.

</TABLE>


In connection with the acquisition of Lasiris, the Company allocated $1.088
million of the purchase price to incomplete research and development projects.
This allocation represents the estimated fair value based on risk-adjusted cash
flows related to the incomplete products. At the date of acquisition, the
development of these projects had not yet reached technological feasibility and
the R&D in progress had no alternative future uses. Accordingly, these costs
were expensed as of the acquisition date.

     Lasiris' acquired research and development value is comprised of R&D
programs designed to significantly enhance the Company's current product line,
as well as develop new laser products and technologies. Management expects that
the projects will be completed from the fourth quarter of 1998 through 2000. At
the acquisition date, programs ranged in completion from 10% to 80%, and
aggregate continuing R&D commitments to complete the projects are expected to be
approximately $1.5 million. The acquired R&D represents developmental efforts
associated with the introduction of new and enhanced laser systems. Remaining
development activities for these programs include the research, development and
testing of advanced electronic, optical, and thermal technologies. Expenditures
to complete these projects are expected to total approximately $400,000 in 1998,
$500,000 in 1999, and $500,000 in 2000. These estimates are subject to change,
given the uncertainties of the development process, and no assurance can be
given that deviations from these estimates will not occur.

         As evidenced by their continued support for these projects, management
believes the Company has a reasonable chance of successfully completing each of
the major R&D programs. However, there is a substantial risk associated with the
completion of the projects and there is no assurance that any will meet with
either technological or commercial success. If none of the R&D projects is
successfully completed, the sales and profitability of the combined company
would be adversely affected and the value of the R&D projects will not be
realized.

         Further information about the acquisition of Lasiris may be found in
the Company's Form 8-K, which was filed with the Securities and Exchange
Commission (the "SEC") on May 27, 1998, and amended on Form 8-K/A, filed with
the SEC on July 27, 1998.

NOTE 4.  WRITE DOWN OF GOODWILL

         In accordance with the provisions of Statement of Financial Standards
(SFAS) No. 121 - "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of", the Company periodically assesses the
realizability of its long-lived assets. In addition to this periodic review, the
Company is obliged to initiate such an assessment in the event of a change in
the Company's assets or in the valuation of its assets. Based on its most recent
assessment, the Company has recorded a non-recurring, non-cash charge of $7.4


                                       5

<PAGE>




million during the three months ended June 30, 1998, to write down the carrying
value of its goodwill to its estimated fair value.

         On July 14, 1998, the Company announced that it had signed a
non-binding letter of intent to sell its Stilson Division ("Stilson"). As of
June 30, 1998 the carrying value of Stilson's net assets was $2.0 million plus a
portion of the goodwill recorded in 1989 when Stocker & Yale (the "Company"),
including Stilson, was acquired. This proposed sale of Stilson required the
Company to assess the realizability of goodwill. There was no allocation of
goodwill to the individual divisions of the Company at the time of the
acquisition in 1989. Accordingly, management of the Company has evaluated the
cash flow generated by Stilson for the five years preceding and the five years
following the acquisition relative to the cash flow of the entire Company.
Management has also reviewed their expectations, at the time of the 1989
acquisition, of the future cash flow of Stilson. Based on this assessment
management has allocated approximately 60% of the goodwill resulting from the
1989 acquisition to Stilson, $4.9 million net of amortization at June 30, 1998.
Therefore the net assets of Stilson at June 30, 1998 inclusive of goodwill were
approximately $6.9 million. The purchase price for the net assets of Stilson set
forth in the letter of intent is $3.0 million. Accordingly, at June 30, 1998 the
Company has written down the carrying value of the net assets of Stilson to $3.0
million and recorded a charge of $3.9 million which is included in the goodwill
impairment in the three-month period ended June 30, 1998.

         Subsequent to the allocation of goodwill to Stilson, management
assessed the realizability of the remaining $3.5 million balance of its 1989
goodwill. Based upon the changes in the Company since 1989 and the recent
history of losses, management concluded that the realizability of the remaining
goodwi1l is uncertain and that the carrying value should be written down to
zero. The Company has incurred consolidated operating losses of approximately
$644,000 and $374,000 for fiscal years ended December 31, 1997 and 1996. During
both periods as indicated in footnote (10) of the consolidated financial
statements, the Measuring and Inspection Instruments segment (the "Stocker"
segment) incurred operating losses of approximately $325,000 and $384,000 in
fiscal 1997 and 1996 respectively, whereas the Stocker segment recorded
operating profits of approximately $64,000 in 1995. In spite of the Company's
concerted efforts to turnaround these negative operating results, it has not
been successful. Since the 1989 acquisition, the Company has experienced a shift
from U.S. government purchases under long-term government contracts to a
civilian customer-base that has not been sufficient to cover the loss of its
governmental business. Furthermore, in spite of management's efforts, the
operating profits of its other measuring and inspection products have also
declined. Management believes that the Company's future growth lies in product
lines, such as fiber optic lighting and laser lighting which were not part of
the 1989 goodwill. Due to the uncertainty of this business, management is unable
to predict when or if Stocker will generate operating profits. As a result of
this assessment the Company adjusted the value of its Stocker goodwill to zero.

                  ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS
                  OF FINANCIAL CONDITION AND OPERATING RESULTS

         This Quarterly Report on Form 10-QSB contains forward looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. The Company's actual results
could differ materially from those set forth in the forward-looking statements.

RESULTS OF OPERATIONS

         The following discussion should be read in conjunction with the
attached consolidated financial statements and notes thereto and with the
Company's audited financial statements and notes thereto for the fiscal year
ended December 31, 1997.

THREE-MONTH PERIODS ENDED JUNE 30, 1998 AND 1997

         On May 13, 1998, the Company completed its purchase of all of the
outstanding stock of 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"). The acquisition was
accounted for as a purchase, and the purchase price


                                       6

<PAGE>



was allocated pursuant to an independent appraisal. The three month results
include the effects of increased goodwill amortization totaling $20,196,
increased depreciation of acquired assets totaling $37,202, as well as the
results of Lasiris operations for the period since the acquisition date. In
addition, $1,087,914 of in-process research & development projects of Lasiris
was charged against income. This portion of the assets acquired was identified
as projects that had not yet reached technological feasibility and that, until
completion of the development, have no alternative future use.

In connection with the acquisition, the stockholders of Lasiris received an
aggregate of approximately $3.2 million in cash and 444,146 shares of LHI's
capital stock which are exchangeable for shares of the Company's common stock on
a one for one basis. 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 of $3.50 per share; (ii) a loan in the amount of $750,000 from a bank
which is secured by a second mortgage interest in the Company's headquarters;
(iii) a loan of approximately $800,000 pursuant to a credit agreement with the
Toronto Dominion Bank and Lasiris; and (iv) cash received of $950,000 pursuant
to the prepayment of a note receivable due to the Company. The acquisition was
accounted for as a purchase, and accordingly, the initial purchase price and
acquisition costs aggregating approximately $5.5 million have preliminarily been
allocated to the assets acquired, which consist of approximately $4.0 million in
identifiable assets, approximately $0.4 million in goodwill, and approximately
$1.1 million of in-process research and development which was charged to
operations in the second quarter of 1998. The purchase price allocations
represent the fair values determined by an independent appraisal.

The following outlines the allocation of purchase price for the acquisition of
Lasiris.

In connection with the acquisition of Lasiris, the Company allocated $1.088
million of the purchase price to incomplete research and development projects.
This allocation represents the estimated fair value based on risk-adjusted cash
flows related to the incomplete products. At the date of acquisition, the
development of these projects had not yet reached technological feasibility and
the R&D in progress had no alternative future uses. Accordingly, these costs
were expensed as of the acquisition date.

         Lasiris' acquired research and development value is comprised of R&D
programs designed to significantly enhance the Company's current product line,
as well as develop new laser products and technologies. Management expects that
the projects will be completed from the fourth quarter of 1998 through 2000. At
the acquisition date, programs ranged in completion from 10% to 80%, and
aggregate continuing R&D commitments to complete the projects are expected to be
approximately $1.5 million. The acquired R&D represents developmental efforts
associated with the introduction of new and enhanced laser systems. Remaining
development activities for these programs include the research, development and
testing of advanced electronic, optical, and thermal technologies. Expenditures
to complete these projects are expected to total approximately $400,000 in 1998,
$500,000 in 1999, and $500,000 in 2000. These estimates are subject to change,
given the uncertainties of the development process, and no assurance can be
given that deviations from these estimates will not occur.

         As evidenced by their continued support for these projects, management
believes the Company has a reasonable chance of successfully completing each of
the major R&D programs. However, there is a substantial risk associated with the
completion of the projects and there is no assurance that any will meet with
either technological or commercial success. If none of the R&D projects is
successfully completed, the sales and


                                       7

<PAGE>



profitability of the combined company would be adversely affected and the value
of the R&D projects will not be realized.

         Consolidated net revenues increased 9% from $2,804,280 in the second
quarter of 1997 to $3,057,442 in the second quarter of 1998. Of the total net
revenues reported for the three-month period ended June 30, 1998, the Company's
Salem Division, located in Salem, New Hampshire, contributed 52%, the Company's
Stilson/Die-Draulics Division, located in Fraser, Michigan, contributed 33%,
Lasiris contributed 12% and Radiant Asiatec Pte, Ltd. contributed 2%. Despite
significantly reduced sales to Southeast Asia, Lighting Products revenues
increased 72% from $1,003,846 to $1,726,119 due to the addition of $676,995 in
laser lighting revenues contributed by Lasiris and $123,214 in microscope
lighting revenues contributed by the Singapore subsidiary. Lighting Products
revenue further benefited from fiber optic lighting sales which increased from
$81,762 to $187,240. Sales of the Company's Military Products decreased overall
from $460,923 in the second quarter of 1997 to $109,111 in the second quarter of
1998. Civilian sales of Military Products decreased $148,987 from $236,693 to
$87,706 reflecting the absence in the current year of a large contract with a
direct mail marketing firm which favorably impacted 1997, and also reflecting
the closing in December, 1997 of the Company's Hong Kong subsidiary which sold
such products. Sales of Military Products to the U.S. Government decreased
$112,531 from $133,936 in the second quarter 1997 to $21,405 in the second
quarter 1998, as peacetime demand for military supplies continues to diminish.
Sales of Machine Tool and Accessories decreased from $1,000,193 in the second
quarter of 1997, to $833,739 in the second quarter of 1998, due to a slowdown in
distributor orders. Sales of Printer and Recorder Products increased from
$339,318 in the second quarter of 1997, to $388,473 in the second quarter of
1998.

         Gross profit decreased $32,213 from $1,189,842 in the second quarter of
1997 to $1,157,629 in the second quarter of 1998, as personnel costs increased
and the Company experienced reduced revenues at the Company's Stilson and Salem
Divisions. Selling Expenses increased $28,850, with Lasiris selling expenses of
$101,252 offsetting $72,402 in reduced costs of sales personnel in other
divisions.

         Research and Development Expenses increased by $39,505 primarily
reflecting the amount of such expenses at Lasiris. General and Administrative
costs increased $491,844 from $467,458 in the second quarter of 1997 to $959,304
in the second quarter of 1998. $321,335 of this increase is attributable to
expenses reported by the Company's new Singapore and Lasiris subsidiaries and
associated corporate expenses, with the balance due largely to increased
personnel costs, legal expenses and bank charges. Interest expense increased
$49,209 as a result of the Company's increased indebtedness.

         In accordance with the provisions of Statement of Financial Standards
(SFAS) No. 121 - "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of", the Company periodically assesses the
realizability of its long-lived assets. In addition to this periodic review, the
Company is obliged to initiate such an assessment in the event of a change in
the Company's assets or in the valuation of its assets. Based on its most recent
assessment, the Company has recorded a non-recurring, non-cash charge of $7.4
million during the three months ended June 30, 1998, to write down the carrying
value of its goodwill to its estimated fair value.

         On July 14, 1998, the Company announced that it had signed a
non-binding letter of intent to sell its Stilson Division ("Stilson"). As of
June 30, 1998 the carrying value of Stilson's net assets was $2.0 million plus a
portion of the goodwill recorded in 1989 when Stocker & Yale (the "Company"),
including Stilson, was acquired. This proposed sale of Stilson required the
Company to assess the realizability of goodwill. There was no allocation of
goodwill to the individual divisions of the Company at the time of the
acquisition in 1989. Accordingly, management of the Company has evaluated the
cash flow generated by Stilson for the five years preceding and the five years
following the acquisition relative to the cash flow of the entire Company.
Management has also reviewed their expectations, at the time of the 1989
acquisition, of the future cash flow of Stilson. Based on this assessment
management has allocated approximately 60% of the goodwill resulting from the
1989 acquisition to Stilson, $4.9 million net of amortization at June 30, 1998.
Therefore the net assets of Stilson at June 30, 1998 inclusive of goodwill was
approximately $6.9 million. The purchase price for the net assets of Stilson set
forth in the letter of intent is $3.0 million. Accordingly, at June 30, 1998,
the Company has written down the carrying value of the net assets of Stilson to
$3.0 million and recorded a charge of $3.9 million which is included in the
goodwill impairment in the three-month period ended June 30, 1998.



                                       8
<PAGE>



         Subsequent to the allocation of goodwill to Stilson, management
assessed the realizability of the remaining $3.5 million balance of its 1989
goodwill. Based upon the changes in the Company since 1989 and the recent
history of losses, management concluded that the realizability of the remaining
goodwill is uncertain and that the carrying value should be written down to
zero. The Company has incurred consolidated operating losses of approximately
$644,000 and $374,000 for the fiscal years ended December 31, 1997 and 1996.
During both periods as indicated in footnote (10) of the consolidated financial
statements, the Measuring and Inspection Instruments segment (the "Stocker"
segment) incurred operating losses of approximately $325,000 and $384,000 in
fiscal 1997 and 1996 respectively, whereas the Stocker segment recorded
operating profits of approximately $64,000 in 1995. In spite of the Company's
concerted efforts to turnaround these negative operating results, it has not
been successful. Since the 1989 acquisition, the Company has experienced a shift
from U.S. government purchases under long-term government contracts to a
civilian customer-base that has not been sufficient to cover the loss of its
governmental business. Furthermore, in spite of management's efforts, the
operating profits of its other measuring and inspection products have also
declined. Management believes that the Company's future growth lies in product
lines, such as fiber optic lighting and laser lighting which were not part of
the 1989 goodwill. Due to the uncertainty of this business management is unable
to predict when or if Stocker will generate operating profits. As a result of
this assessment the Company adjusted the value of its Stocker goodwill to zero.

SIX-MONTH PERIODS ENDED JUNE 30, 1998 AND 1997

         On May 13, 1998, the Company completed its purchase of all of the
outstanding stock of 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"). The acquisition was
accounted for as a purchase, and the purchase price was allocated pursuant to an
independent appraisal. The six month results include the effects of increased
goodwill amortization totaling $20,196, increased depreciation of acquired
assets totaling $37,202, as well as the results of Lasiris' operations for the
period since the acquisition date. In addition, $1,087,914 of in-process
research & development projects of Lasiris was charged against income. This
portion of the assets acquired were identified as projects that had not yet
reached technological feasibility and that, until completion of the development,
have no alternative future use.

         Consolidated net revenues decreased from $5,537,942 in the second
quarter of 1997 to $5,492,783 in the second quarter of 1998. Despite
significantly reduced sales to Southeast Asia, Lighting Products revenues
increased 38% from $1,966,070 to $2,714,491 due to the addition of $676,995 in
laser lighting revenues contributed by Lasiris and $123,214 in microscope
lighting revenues contributed by the Singapore subsidiary. Lighting Products
revenue further benefited from fiber optic lighting sales which increased from
$129,995 to 371,950. Sales of the Company's Military Products decreased overall
from $832,564 in 1997 to $206,681 in 1998. Civilian sales of Military Products
decreased $511,627 from $676,067 in second quarter 1997 to $164,440 in the
second quarter 1998, reflecting the absence in the current year of a large
contract with a direct mail marketing firm which favorably impacted 1997, and
also reflecting the closing in December, 1997 of the Company's Hong Kong
subsidiary which sold such products. Sales of Military Products to the U.S.
government decreased $114,256 from $156,497 in the second quarter 1997 to
$42,241 in the second quarter 1998, as peacetime demand for military supplies
continues to diminish. Sales of Machine Tool and Accessories decreased from
$1,996,717 in the second quarter of 1997 to $1,822,307 in the second quarter of
1998 due to a slowdown in distributor orders. Sales of Printer and Recorder
Products increased from $742,591 in the second quarter of 1997 to $749,304 in
the second quarter of 1998.

         Gross profit decreased $338,115 from $2,281,059 in the second quarter
of 1997 to $1,942,944 in the second quarter of 1998, as personnel costs
increased against reduced revenues at the Company's Stilson and Salem Divisions.
Selling Expenses decreased $73,548, as a result of reduced selling costs at the
Salem and Stilson Divisions, a portion of which reduction was offset by the
addition of Lasiris selling expenses totaling $101,252. Research and Development
Expenses increased $54,966 of which $37,216 resulted from the addition of such
expenses at Lasiris. General and Administrative costs increased $660,788 from
$852,243 in the second quarter of 1997 to $1,513,031 in the second quarter of
1998. $321,335 of this increase is attributable to expenses reported by the
Company's new Singapore and Lasiris subsidiaries and associated corporate
expenses, with the balance due largely to increased personnel costs of $199,194,
increased legal and audit expenses of $143,128, a

$50,000 discount granted for the prepayment of a note due to the Company, and
increased bank charges of $42,495. Interest expense increased $86,448 as a
result of the Company's increased indebtedness.

LIQUIDITY AND CAPITAL RESOURCES

         The Company finances its operations primarily through third party
credit facilities and cash from operations. Net cash used in operations was
($129,524) for the six months ended June 30, 1998 and ($1,401,499) for the six
months ended June 30, 1997.

         The Company's primary third party financing relationship is with Fleet
National Bank of Massachusetts, N.A. (the "Bank"). The initial Credit Agreement
between the Company and the Bank, dated March 6, 1995 (the "Credit Agreement"),
provided for a Revolving Line of Credit Loan (the "Revolving Loan") and a Long
Term Loan (the "Term Loan") both due March 31, 1998. The Short Term Loan was
paid as agreed in August 1995. As of April 1, 1998, the Company and the Bank
entered into an agreement to extend the maturity dates of its Revolving Loan and
Term Loan to January 2, 1999. The Revolving Loan and the Term Loan bear interest
at the Bank's base rate plus 1% through June 30, 1998 and at the Bank's base
rate plus 2% from July 1, 1998 through the maturity date. At June 30, 1998 there
was a total of $2,884,454 borrowed under the Credit Agreement, of which
$1,789,029 pertained to the Revolving Loan. The available credit on the
Revolving Loan as of June 30, 1998 was $292,156.65. The Company is exploring
financing alternatives and intends to refinance before maturity.

         Under the terms of the Credit Agreement, the Company is required to
comply with a quarterly minimum net income covenant. As of June 30, 1998 the
Company was not in compliance with this covenant, and on July 21, 1998 the Bank
granted a waiver of the net income covenant for the quarter ended June 30, 1998.

         In connection with the Lasiris acquisition, the stockholders of Lasiris
received 444,146 shares of capital stock of Lasiris Holdings, Inc., a newly
formed New Brunswick corporation and a subsidiary of the Company, which are
exchangeable for shares of the Company's common stock on a one for one basis and
cash in an aggregate amount of approximately $3.3 million. The aggregate value
of the shares was deemed to be $1,732,167 as of May 13, 1998. The Company
financed a portion of the cash consideration paid for Lasiris through a private
placement of 350,000 shares of the Company's common stock at a price of $3.50
per share, which generated net proceeds to the Company of $1,124,716 after
offering expenses of $100,284.

         On May 13, 1998, the Company entered into a $750,000 second mortgage
loan with Danvers Savings Bank (the "Danvers Loan"). This loan bears interest at
a rate of 11%, requires monthly payments of interest only and matures on May 13,
1999. The Danvers Loan generated net proceeds after expenses of $731,196, which
were used to finance a portion of the Lasiris acquisition.

         Also on May 13, 1998, Lasiris entered into a credit agreement with
Toronto Dominion Bank ("TD Bank"). The credit agreement provides for (i) a
$1,000,000 CDN Operating Line of Credit (the "TD Line of Credit"); (ii) a
$1,000,000 CDN Term Loan (the "TD 4 Year Term Loan"); (iii) a $83,333 CDN Term
Loan (the "TD Two Year Term Loan"); and (iv) a $4,461 CDN Letter of Guarantee
(the "Letter of Guarantee"). The TD Line of Credit bears interest at 1% over the
TD Bank prime rate, requires monthly payments of interest only, and is payable
on demand. As of June 30, 1998, there were no borrowings on the TD Line of
Credit. The TD 4 Year Term Loan bears interest at 2% over the TD Bank prime
rate, matures on May 13, 2002, and requires monthly principal payments of
$20,833CDN (approximately $14,500US) plus interest. As of June 30, 1998, the
outstanding balance on the TD 4-Year Term Loan was $979,966CDN ($667,650 US).
The TD Two Year Term Loan bears interest at 2% over the TD Bank prime rate,
matures on May 13, 2000, and requires monthly principal payments of $4,167 CDN
(approximately $2,900US) plus interest. As of June 30, 1998, the outstanding
balance on the TD 2-Year Term Loan was $79,167CDN ($53,936 US).

         On May 7, 1998, Beverly Hospital Corporation prepaid its $1,000,000
Note Receivable due to the Company, less a $50,000 discount for early payment.
The proceeds were used to finance a portion of the Lasiris acquisition.


                                       10

         On May 20, 1997, the Company entered into a one-year equipment line of
credit agreement with Granite State Bank to finance capital equipment related to
new product development. Under the terms of this agreement, advances under the
line will be converted quarterly into a series of five year notes, not to exceed
$500,000 in the aggregate, which will bear interest at the prime rate plus
0.75%. As of June 30, 1998, the Company had outstanding debt of $346,929 under
this line of credit.

         Accounts payable increased $1,110,010 from December 31, 1997 to June
30, 1998 of which $698,902 results from the Lasiris acquisition and the balance
is attributable to increased payment cycles. Company expenditures for capital
equipment were $388,099 in the first six months of 1998 as compared to $323,602
in the first six months of 1997. The majority of the 1998 expenditures related
to the purchase of new CNC machinery at the Company's Stilson Division.

         On July 14, 1998, the Company announced that it had signed a
non-binding letter of intent to sell its Stilson Division to De-Sta-Co
Industries. Subject to the execution of a definitive purchase and sale agreement
and a due diligence review of the Stilson Division, De-Sta-Co will acquire the
assets of Stilson for $3 million cash, assumption of approximately $1 million of
operating liabilities and semiannual payments of 2% of future Stilson product
line revenues for three years. Although the parties anticipate consummating the
sale on or before September 30, 1998, there can be no assurance as to when such
a transaction would close, if at all, or as to the definitive terms of such a
transaction.

         The Company contemplates that it may seek to raise additional capital
by the issuance of equity the proceeds of which may be used among other things
in connection with refinancing its senior credit facility. The Company's
existing Credit Agreement with the Bank will expire on January 1, 1999 by its
terms. While the Company is currently exploring establishing a replacement
credit facility with various commercial lenders, the Company can give no
assurance as to whether such a replacement credit facility will be established
or as to the terms of such credit facility. Assuming the continued availability
of the Company's Credit Agreement with the Bank or a replacement credit
facility, the Company believes that its available financial resources are
adequate to meet its foreseeable working capital, debt service and capital
expenditure requirements through the next twelve months. If the Company is
unable to refinance or extend its Credit Agreement with the Bank prior to
maturity, then it will be unable to repay such indebtedness when due and the
Bank may declare a default. Were a default to be declared, the Company would not
be able to continue absent alternative financing.

YEAR 2000 ISSUES

         The Company has undertaken a plan to address the potential impact to
its business of "year 2000 issues" (i.e., issues that may arise as a result of
computer programs that use only the last two, rather than all four, digits of
the year). The plan addresses Internal Matters, which are under the Company's
operation and over which the Company exercises some control, and External
Matters, which are outside the Company's control and influence. The Company has
elected first to address Internal Matters, in the belief that most other
companies and institutions are similarly working to resolve their own
mission-critical issues and that as a result an early assessment of External
Matters would be premature.

         The Company has completed a review of its products and product
components, its information systems, and its ancillary systems (such as test
equipment, communication equipment, and security systems) in order to identify
areas of exposure to year 2000 issues. The review concluded that the Company's
products and product components are substantially free from year 2000 risks. The
Company's Engineering department is working with the suppliers of several
product components to ascertain whether identified potential risks have been
addressed and when they will be compliant.

         The Company's information systems rely upon commercial computer
software provided by independent software vendors. The Company's primary
information system software, which consists of computer operating system, an
integrated manufacturing system and a payroll package, was upgraded in 1997 so
that it would function with the Company's upgraded computer system hardware. The
cost for the new software was approximately $80,000. The providers of these
primary information system software packages have represented that these systems
are fully Year 2000 compliant. The Company also utilizes a number of personal
computers which are operated independently (i.e., not linked by a network).
These computers use a wide variety of

                                       11

<PAGE>




different software packages and are of various ages. The Company has compiled an
inventory of these personal computers, their hardware, as well as their
operating systems and installed application software packages. This information
will be assessed initially to determine if suppliers represent that they are
year 2000 compliant. The Company estimates that it has completed approximately
75% of this assessment. Following the assessment phase, the Company will
undertake to upgrade or replace software and, if necessary, will replace
personal computers so that all equipment and software is represented compliant
by the providers. The Company estimates that the cost for such upgrades and
replacements will not exceed $30,000. Subsequent phases will include obtaining
written certification of year 2000 testing by providers followed by our own
in-house year 2000 tests.

         The Company's ancillary systems are largely provided by third parties,
most of which have not yet completed their own assessments of year 2000
exposure. The Company will continue to solicit such information from these third
parties. Due to the incompleteness of this information, contingency plans have
not yet been finalized.

         The Company estimates that it has completed approximately 45% of its
year 2000 Plan regarding Internal Matters and estimates that it has completed
approximately 20% of its overall year 2000 plan.

         For all purposes of this Agreement and the other Loan Documents, except
as otherwise expressly provided herein or therein or unless the context
otherwise requires:

         (i)        references to any person defined in this Agreement refer to

                    administrators and other legal representatives;

         (ii)       references to any agreement, instrument or document defined
                    in this Agreement refer to such document as originally

                    modified, amended, restated or supplemented from time to
                    time, as so varied, extended, renewed, modified, amended,

         2.1      CREDIT COMMITMENT

         Subject to the conditions hereinafter contained and so long as no
Default exists or Event of Default has occurred hereunder and is continuing, the
Bank may, at its sole discretion, make available to the Borrower (i) a credit
facility up to a maximum amount of one million dollars ($1,000,000) in lawful
currency of Canada (the "Operating Line of Credit") which the Borrower may
utilize, repay and reutilize from time to time in accordance with the provisions
hereof or as otherwise permitted by the Bank, provided that the aggregate
principal amount of all utilizations outstanding under the Operating Line of
Credit at any particular time does not exceed the Operating Available Commitment
at that time, and (ii) a credit facility up to a maximum amount of one million
dollars ($1,000,000) in lawful currency of Canada (the "Demand Acquisition
Loan") which the Borrower may utilize, by way of one single draw on or before
May 31, 1998, and repay in accordance with the provisions hereof or as otherwise
permitted by the Bank.

         2.2      USE OF LOAN

         All proceeds from the Operating Line of Credit, other than an amount of
up to $400,000 which may also be used in the same manner as the Demand
Acquisition Loan, shall only be used for general working capital purposes of the
Borrower. Notwithstanding anything to the contrary contained in any of the Loan
Documents, the Borrower shall not, subject to the previous sentence, use,
directly or indirectly, any of the proceeds of the Operating Line of Credit by
way of loan, advance or investment to or in any other member of the Borrower

                                    each such date (except to the extent that
                                    such representations and warranties
                                    expressly relate to an earlier date), and no
                                    Default shall exist and no Event of Default
                                    shall have occurred and be continuing, or
                                    would result from such utilization;

                           (c)      the resolutions referred to in Section 3.1.6

                                    regulation or interpretation thereof that,
                                    in the opinion of counsel for the Bank,
                                    would make it illegal or against the policy
                                    of any governmental agency or authority for
                                    the Bank to provide any utilization of any
                                    of the Credit Facilities hereunder, and, in
                                    the event that there is any change in law,
                                    regulation or interpretation thereof that
                                    requires a withholding tax to be paid in
                                    connection with this Agreement and any of
                                    the Credit Facilities made hereunder, the
                                    Borrower has acknowledged that such change
                                    has occurred and has agreed that the
                                    provisions contained in Section 10 shall be
                                    in effect.

         The providing of any utilization under any of the Credit Facilities and
the continuation or conversion of any such utilization under any of the Credit
Facilities shall be deemed to be, on the date of such utilization, continuation
or conversion under the Credit Facilities, a representation and warranty by each
member of the Borrower Affiliated Group, as to the accuracy in all material
respects of the representations and warranties referred to in subsection 3.2(b).

Without diminishing the right of the Bank to require payment of the unpaid
balance of the Demand Acquisition Loan and all accrued and unpaid interest
thereon on demand, the Borrower shall, on the first Business Day of each month,
pay to the Bank an amount equal to the lesser of (i) the unpaid balance of the

principal amount owing under the Demand Acquisition Loan.

         4.3      BREAKAGE COSTS

breakage costs in connection with an early termination of any outstanding
portion of any of the Credit Facilities, such costs will be added to the
indebtedness of the Borrower to the Bank hereunder and shall be payable on
demand.

5.       INTEREST

         5.1      PRIME RATE LOAN

         Subject to the last paragraph of Section 7.1, the unpaid balance of the
Prime Rate Loan from time to time shall bear interest in respect of each day,
both before and after maturity or default, at a rate per annum which shall be at
all times equal to the Prime Rate of the Bank plus the Applicable Margin from
time to time in effect, such rate to be automatically adjusted without notice to
the Borrower effective immediately upon every change by the Bank of its Prime
Rate. Such interest shall be calculated daily and shall be payable monthly in

7.       BANKERS' ACCEPTANCES

         7.1      ISSUE OF BANKERS' ACCEPTANCES

         The Borrower may from time to time, at its option, utilize any of the
Credit Facilities or, subject to the terms hereof, part thereof by issuing
Bankers' Acceptances denominated in Canadian Dollars, provided that each such
utilization is in an aggregate principal amount of at least $500,000 and, over
that amount, in increments of $100,000. Such utilization may be by way of
conversion of the Prime Rate Loan or part thereof. Bankers' Acceptances issued
by the Borrower hereunder shall be for a term determined at the sole discretion
of the Bank but, in any event, of not less than 30 days and not more than 365
days, shall be prepared on the Bank's own forms supplied to the Borrower for
such purpose together with such other documents as the Bank may require and
shall be preceded by a verbal notice of the Borrower to the Bank setting out:

                           (a)      the intended date of issue;

                           (b)      the requested maturity date of the issue;

                           (c)      the amount of each denomination and the
                                    aggregate face amount thereof; and

                           (d)      where the Bankers' Acceptances have been
                                    pre-negotiated by the Borrower to a person
                                    other than the Bank, the name and address of
                                    such person who will accept delivery against
                                    payment and the amount of such payment.

         The verbal notice hereinabove referred to shall be given by the
Borrower to the Bank three Business Days prior to the intended date of issue of
any Bankers' Acceptances and shall be confirmed by a Notice of Borrowing,
Renewal or Conversion not later than on presentation by the Borrower to the Bank
for acceptance of the Bankers' Acceptances.

         Upon the issue of each Bankers' Acceptance as a result of the renewal
of outstanding Bankers' Acceptances, the Borrower shall, concurrently with such
renewal, pay in advance out of its own funds to the Bank an amount equal to the
Discount applicable to such issue, to be applied against the principal of the
Bankers' Acceptance being so renewed, plus the applicable stamping fee set out
in Section 7.4.

         If the Borrower chooses to renew a Bankers' Acceptance, the Borrower
shall cause the term of the new Bankers' Acceptances to commence on and include
the date of maturity of the relative Bankers' Acceptances being renewed. If the
Borrower fails to notify the Bank of its intention to renew a Bankers'
Acceptance at the latest by 10:00 a.m. three Business Days preceding the date of
maturity of such Bankers' Acceptance, the Borrower shall be deemed to have
notified the Bank of its intention to convert such Bankers' Acceptance into a
Prime Rate Loan. If the Borrower does not give the Bank three Business Days
prior notice of its intention to renew a Bankers' Acceptance, interest on the
amount of the Prime Rate Loan resulting from the maturity of such Bankers'
Acceptance shall be calculated daily and be payable on the date of the next
interest payment in respect of such Prime Rate Loan at an annual rate equal to
115% of the applicable Prime Rate and

                                       8

<PAGE>



Applicable Margin for each day of the three-day period immediately following
such maturity; thereafter, the rate of interest shall be calculated and payable
in accordance with Section 5.1.

         7.2      REPAYMENT OF BANKERS' ACCEPTANCES

         Bankers' Acceptances issued by the Borrower hereunder shall be made
payable at the branch of the Bank set forth in Appendix I hereof. If in respect
of maturing Bankers' Acceptances, the Borrower fails to give the Bank a timely
notice of renewal as provided in Section 7.1, such Bankers' Acceptances so
maturing shall be paid by the Bank and, subject to the last paragraph of Section
7.1, the amount thereof shall be added to the Prime Rate Loan bearing interest
in accordance with Section 5.1.

         Notwithstanding the foregoing, the repayment on any day of maturing
Bankers' Acceptances from floating rate funds borrowed from the Bank hereunder
or otherwise is subject to the Bank's then applicable floating interest rate
being equal to or greater than the sum of the Bank's discount rate for 30-day
Bankers' Acceptances plus the aggregate of the Acceptance Rate of the Bank in
effect on such day and the Applicable Margin; failing which such repayment may
be subject to the Bank's prior consent which will not be unreasonably withheld.

         7.3      TIMING OF MATURITIES

         Subject to the terms hereof, no Bankers' Acceptance may be prepaid by
the Borrower prior to the scheduled maturity thereof, and in issuing Bankers'
Acceptances hereunder, the Borrower shall time the maturity thereof such that
the Demand Acquisition Loan never exceeds the Demand Acquisition Available
Commitment from time to time and the Operating Line of Credit never exceeds the
Operating Available Commitment from time to time.

         7.4      STAMPING FEE

         Bankers' Acceptances issued by the Borrower hereunder and accepted by
the Bank shall be subject to a stamping fee payable by the Borrower to the Bank
on the day of acceptance thereof, calculated on the basis of the actual number
of days for which such Bankers' Acceptances are issued, at an annual rate equal
to the Acceptance Rate of the Bank then in effect plus the Applicable Margin.

         7.5      ALTERNATE BASIS OF BORROWING

         If at any time during the term of this Agreement, the Bank determines
in good faith (which determination shall be final, conclusive and binding upon
all members of the Borrower Affiliated Group) that by reason of circumstances or
changes affecting the market for Bankers' Acceptances:

         (i)      it is no longer possible to establish the Acceptance Rate in
                  respect of Bankers' Acceptances, or

         (ii)     the market for Bankers' Acceptances no longer exists, is too
                  weak for its normal use by the Bank or is not capable in the
                  normal course of business to absorb Bankers' Acceptances
                  accepted by the Bank,

then, the Bank shall immediately notify the Borrower of its determination in
writing. For so long as

                                       9

<PAGE>





the circumstances referred to in paragraphs (i) or (ii) of this Section shall
continue, the Bank shall not be obligated to make any further utilizations under
any of the Credit Facilities available by way of Bankers' Acceptances and
thereafter, until notice to the contrary is given to the Borrower by the Bank,
the Bank shall only be obligated to make other forms of utilizations under the
Credit Facilities available to the Borrower hereunder.

         7.6      WAIVER OF CLAIM

         The Borrower shall have no right to set up as against the Bank any
defense or right of action, of indemnification or of set-off or compensation or
any similar claim of any nature whatsoever which the Borrower may have had at
any time or may have in the future with respect to any holder of one or more
Bankers' Acceptances issued pursuant hereto.

         7.7      PRE-SIGNED DRAFT FORMS

         To enable the Bank to make utilizations available by way of Bankers'
Acceptances in the manner specified in this Section 7, the Borrower shall, in
accordance with the request of the Bank, either (i) provide a power of attorney
to complete, sign, endorse and issue Bankers' Acceptances, in such form as the
Bank may require; or (ii) supply the Bank with such number of drafts as the Bank
may reasonably request, duly endorsed and executed on behalf of the Borrower.
The Bank will, upon request by the Borrower, promptly advise the Borrower of the
number and designations, if any, of the uncompleted drafts then held by it.

         7.8      EXECUTION OF BANKERS' ACCEPTANCES

         Subject to Section 7.7, drafts of the Borrower to be accepted as
Bankers' Acceptances hereunder shall be signed by a duly authorized officer or
duly authorized officers of the Borrower. Notwithstanding that any person whose
signature appears on any Bankers' Acceptance as one of such officers may no
longer be an authorized signatory for the Borrower at the date of issuance of a
Bankers' Acceptance, such signature shall nevertheless be valid and sufficient
for all purposes as if such authority had remained in force at the time of such
issuance and any such Bankers' Acceptance so signed shall be binding on the
Borrower. The Bank shall not be responsible or liable for its failure to accept
a Bankers' Acceptance as required hereunder if the cause of such failure is, in
whole or in part, due to the failure of the Borrower to provide duly executed
and endorsed drafts to the Bank on a timely basis nor shall the Bank be liable
for any damage, loss or other claim arising by reason of any loss or improper
use of any such instrument except a loss or improper use arising by reasons of
the gross or intentional fault of the Bank or its employees.

8.       LETTERS OF CREDIT

         8.1      LETTERS OF CREDIT

         The Borrower may utilize a portion of the Operating Line of Credit by
way of Letters of Credit, subject to the terms and conditions of this Agreement,
upon the Borrower making a request to the Bank.

         8.2      ISSUANCE

         Upon request by the Borrower and subject to the provisions of this
Agreement, the Bank shall issue from time to time such Letters of Credit as the
Borrower shall request. For purposes of calculating such utilization of the
Operating Line of Credit, the nominal face amount of each Letter of Credit shall
be used. The terms of each Letter of Credit shall be for a term determined
between the parties but, in any event, shall not exceed one year from the date
of issuance thereof.

         8.3      DOCUMENTATION

         Any request for a utilization under the Operating Line of Credit by way
of Letters of Credit shall be accompanied by the Bank's usual documentation
relating to the issuance and administration of letters of credit, duly executed
by the Borrower.

         8.4      FEES

         Upon issuance of a Letter of Credit, the Borrower shall pay to the Bank
a fee calculated in accordance with the standard practice of the Bank at a rate
per annum equal to the rate as advised by the Bank to the Borrower at the time
of issuance of the Letter of Credit calculated on the face amount of such Letter
of Credit, payable with other standard fees applicable at the time of issuance.

         8.5      DISCHARGE OF OBLIGATIONS

         The Borrower agrees to reimburse the Bank in immediately available
funds the amount paid or to be paid by the Bank or its agent or any party on its
behalf on any Letter of Credit issued on behalf of the Borrower which is
presented for payment. The Borrower agrees that while any Letter of Credit is
outstanding, the Borrower will take whatever steps are necessary to ensure that
it is entitled to obtain a utilization pursuant to the provisions hereof in an
amount at least equal to the principal amount of such Letter of Credit.

         8.6      DEMAND

         If any Letter of Credit is outstanding on the date of demand of
repayment of the Operating Line of Credit hereunder, the Borrower shall
forthwith upon such occurrence pay to the Bank an amount (the "deposit amount")
equal to the principal amount of such Letter of Credit, such deposit amount to
be held by the Bank in a daily interest bearing account for application against
the indebtedness owing by the Borrower to the Bank in respect of any draw on
such Letter of Credit. In the event that the Bank is not called upon to make
full payment on such Letter of Credit prior to the expiry date therefor, the
deposit amount and all interest accrued thereon, or such part thereof as has not
been paid out, shall be applied first to any other amounts payable pursuant to
the Letter of Credit and then to any other amount owing by the Borrower to the
Bank under the Loan Documents. Any amount and accrued interest remaining shall
be returned to the Borrower within 30 days of the expiry of the Letter of
Credit.

9.       AVAILABLE COMMITMENT CANCELLATIONS

         9.1      CANCELLATIONS BY BORROWER

         The Borrower shall have the option at any time and from time to time,
subject to giving the Bank two Business Days irrevocable prior written notice to
that effect, to cancel all or part of the Operating Available Commitment
hereunder, thus permanently reducing the Operating Available Commitment by an
equal amount effective as and from the day that such cancellation takes effect.
No such cancellation can be made for less than Can. $100,000 or whole multiples
thereof except where the entire balance of the Available Commitment is
cancelled.

         9.2      CANCELLATIONS BY BANK

         Notwithstanding anything to the contrary set out herein, the Bank may
cancel forthwith upon notice to the Borrower all or part of the Operating
Available Commitment upon the terms and for the amounts determined at the sole
discretion of the Bank.

         9.3      PAYMENTS AFTER CANCELLATION

         Where on the effective date of a cancellation of all or any part of the
Operating Available Commitment, the unpaid balance of the Operating Line of
Credit is greater than the Operating Available Commitment as reduced pursuant to
the provisions hereof, the Borrower shall pay the difference to the Bank first
by paying down the Prime Rate Loan and, to the extent necessary, by reimbursing
outstanding Bankers' Acceptances on a timely basis in accordance with the
scheduled maturity thereof.

10.      CHANGES IN CIRCUMSTANCES

         10.1     INCREASED COSTS

         If (i) the introduction of or any change in any applicable law,
regulation, treaty or official directive or regulatory requirement now or
hereafter in effect (whether or not having the force of law), or in the
interpretation or application thereof by any court or by any judicial or
governmental authority charged with the interpretation or administration
thereof, (ii) the Bank's compliance with any request from any central bank or
other fiscal, monetary or other authority (whether or not having the force of
law), or (iii) any directive, assessment or reassessment made by any competent
tax authority,

                           (a)      subjects the Bank to any Tax, or changes the
                                    basis of taxation of payments due to the
                                    Bank or increases any existing Tax on
                                    payments of principal, interest or other
                                    amounts payable by any member of the
                                    Borrower Affiliated Group to the Bank under
                                    any of the Loan Documents;

                           (b)      imposes, modifies or deems applicable any
                                    reserve, special deposit,

                                    regulatory or similar requirement against
                                    assets held by, or in respect of deposits in
                                    or for the account of, or loans by, or any

                                    funds for loans by, the Bank, or in respect
                                    of any unutilized portion of the Operating
                                    Available Commitment hereunder; or

                           (c)      imposes on the Bank or modifies any
                                    requirement that capital resources of the
                                    Bank be maintained or allocated in respect
                                    of any of the Credit Facilities or any
                                    unutilized portion of the Operating
                                    Available Commitment hereunder, or imposes
                                    any other Tax or condition with respect to
                                    any of the Loan Documents;

and the result of (a), (b) or (c) is, in the sole determination of the Bank
acting in good faith, to create a liability or increase the cost to the Bank of
maintaining any of the Credit Facilities or other commitments outstanding
hereunder, if any, or to reduce the net income receivable by the Bank or its
effective return on capital in respect of any of the Credit Facilities or other
commitments outstanding hereunder, if any, by an amount which the Bank considers
material in its reasonable discretion, then the Bank shall promptly notify the
relevant member of the Borrower Affiliated Group in writing (which notification
shall be final, conclusive and binding on all members of the Borrower Affiliated
Group) of such determination setting forth the basis thereof and the relevant
member of the Borrower Affiliated Group shall either, at its option:

                           (d)      pay to the Bank, within thirty (30) days
                                    from the date of notification, that amount
                                    which compensates the Bank for such
                                    additional cost or liability, or such
                                    reduction in income or return on capital,
                                    with interest thereon, from the date of
                                    notification until payment in full, at the
                                    Prime Rate plus 2% per annum; or

                           (e)      make with the Bank such other arrangements
                                    as the Bank shall deem satisfactory for the
                                    termination of such facilities or their
                                    conversion into other loans or facilities
                                    available to the Borrower hereunder.

         10.2     ILLEGALITY

         If the introduction of or any change in any applicable law, regulation,
treaty or official directive or regulatory requirement now or hereafter in
effect (whether or not having the force of law), or the interpretation or
application thereof by any court or by any judicial or governmental authority
charged with the interpretation thereof, makes it unlawful or prohibited for the
Bank (based on the opinion of its counsel) to make, to fund, to maintain or to
perform its obligation under any of the Loan Documents or in respect of any
commitment hereunder, if any, the Bank may, by prior written notice to the
Borrower given with a reasonable time period taking into account all
circumstances, terminate its obligations under this Agreement to make available
any of the Credit Facilities or to maintain such commitment, whereupon the
Borrower shall either, at its option:

                           (a)      pay to the Bank the outstanding amount of
                                    the Credit Facilities or portion thereof
                                    which has been determined to be unlawful or
                                    prohibited, such payment (together with
                                    accrued and unpaid interest


                                       13

<PAGE>



                                    thereon) to be made by the Borrower not
                                    later than on the Business Day immediately
                                    preceding the day on which such illegality
                                    or prohibition takes effect; or

                           (b)      make with the Bank such other arrangements
                                    as the Bank shall deem satisfactory for the
                                    termination of such facilities or their
                                    conversion into other loans or facilities
                                    available to the Borrower hereunder and
                                    indemnify the Bank for any out-of-pocket
                                    expenses incurred by the Bank as a result of
                                    such termination or conversion.

11.      LOAN ACCOUNTS AND PLACE OF PAYMENT

         The utilization of any of the Credit Facilities by the Borrower
hereunder and the repayment thereof pursuant to the provisions hereof shall be
evidenced by accounts of the Borrower opened and maintained on the books of the
Bank, which shall debit the amount of each utilization to the appropriate
account and shall credit each payment made by the Borrower to the Bank on
account thereof, by appropriate entries. In the event of any dispute between any
member of the Borrower Affiliated Group and the Bank, such accounts shall, in
the absence of manifest error, constitute conclusive evidence of the Borrower's
obligations hereunder. The unpaid principal amount of the relevant portion of
the Credit Facilities at any time shall be determined by adding the debit
balance of the Borrower's said accounts with the Bank at such time plus the
aggregate face amount of all Bankers' Acceptances and Letters of Credit then
outstanding.

         The Borrower shall make all payments of principal, interest or
otherwise pursuant to this Agreement to the Bank in lawful currency of Canada,
in immediately available funds and before 1:00 p.m. on the day specified for the
payment at the address of the Bank set out in Appendix I hereof, or at any other
place of business of the Bank in Canada or the United States of America of which
the Bank may from time to time notify the Borrower in writing.

12.      REPRESENTATIONS AND WARRANTIES

         Each member of the Borrower Affiliated Group represents and warrants to
the Bank that:

         12.1     ORGANIZATION AND GOOD STANDING

exercised due diligence to qualify each member of the Borrower Affiliated Group
as a foreign corporation in the various jurisdictions wherein the nature of the
business they transact or the character of the properties they own therein makes
such qualification necessary. The Borrower is the wholly owned subsidiary of NB
Inc. which is a wholly-owned subsidiary of Stocker & Yale.

                                    may be subject; and

                           (b)      no member of the Borrower Affiliated Group
                                    is in default under (i) any law, rule,
                                    regulation, order, writ, judgment,

         12.3     VALIDITY OF LOAN DOCUMENTS

         Each one of the Loan Documents is, and the Ancillary Documents when
executed will be, the legal, valid and binding obligations of each member of the
Borrower Affiliated Group party thereto enforceable against such member of the
Borrower Affiliated Group in accordance with their respective terms except as
the enforceability may be limited by applicable bankruptcy, insolvency,
reorganization or other laws from time to time in effect relating to or
affecting the rights of creditors. No authorization, consent, approval, license,
exemption of or filing or registration with any court or governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, is or will be necessary to the valid execution, delivery or performance
by the applicable member of the Borrower Affiliated Group of the Loan Documents,
except such authorizations and filings as have been obtained prior to the date
hereof.

         12.4     NO LITIGATION

         Except as disclosed in a letter dated the date of this Agreement to the
Bank (the "Disclosure Letter") attached as Appendix III to this Agreement, and
as otherwise disclosed in writing to the Bank from time to time after the date
hereof, there are no actions, suits or proceedings pending or, to the knowledge
of any member of the Borrower Affiliated Group, threatened against any member


                                       15

<PAGE>



of the Borrower Affiliated Group, or any of their respective properties or
assets, before any court or governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, which, if determined adversely
to any member of the Borrower Affiliated Group, would have a Material Adverse
Effect. Except as set forth in the Disclosure Letter attached as Appendix III,
no material patent owned by any member of the Borrower Affiliated Group has been
challenged in any such pending or threatened action, suit or proceeding.

         12.5     ACCURACY OF FINANCIAL INFORMATION

         The audited consolidated balance sheet of Stocker & Yale and its
consolidated subsidiaries as at December 31, 1997 and the related statements of
income and of cash flows for the year then ended (collectively, the "Financial
Statements"), all heretofore furnished to the Bank, fairly present the financial
condition and results of operations of Stocker & Yale and its consolidated
subsidiaries as at the dates and for the periods therein referred to and were
prepared in accordance with US GAAP. The financial statements most recently
delivered pursuant to Section 13.2 or Section 13.3 hereof fairly present the
financial condition and results of Stocker & Yale and its consolidated
subsidiaries or the Borrower, as the case may be, as at the dates and for the
periods therein referred (subject to year-end audit adjustments and the absence
of footnotes in the case of interim financial statements) and were prepared in
accordance with US GAAP or Canadian GAAP, as the case may be, and, for the
Borrower, are complete and correct in all material respects; and there has been
no Material Adverse Effect since the date of the last delivery of financial
information pursuant to Section 13.2 or 13.3 hereof. Except as set forth in the
Disclosure Letter attached as Appendix III, there are no material liabilities of
Stocker & Yale or any of the consolidated subsidiaries, fixed or contingent,
which are not reflected in such Financial Statements or in the notes thereto,
other than liabilities incurred in the ordinary course of business since
December 31, 1997, or, of Stocker & Yale or any of the consolidated subsidiaries
or the Borrower, as the case may be, in such financial statements delivered
pursuant to Section 13.2 or Section 13.3 or the footnotes thereto (if any) other
than in the ordinary course of business since the financial statements most
recently delivered pursuant to Section 13.2 to Section 13.3 hereof. All
financial statements, excluding any forecasts, furnished by any member of the
Borrower Affiliated Group to the Bank in connection with the negotiation and
execution of this Agreement do not, and all financial statements hereafter
furnished by any member of the Borrower Affiliated Group to the Bank pursuant to
this Agreement (excluding reports delivered from time to time pursuant to
Section 13.2 or Section 13.3 hereof) will not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
contained therein not misleading in the circumstances in which made.

         12.6     COMPLIANCE

         To the best of their knowledge, except as described in the Disclosure
Letter attached as Appendix III, each member of the Borrower Affiliated Group
(i) is in compliance in all material respects with all applicable laws and
regulations material to the conduct of its business and operations; and (ii)
possesses all the franchises, permits, licenses and grants of authority
necessary or required in the conduct of its respective business, except for
those franchises, permits, licenses and grants of authority the non-obtainment
of which would not have a Material Adverse Effect, and such franchises, permits,
licenses and grants of authority which each member of the Borrower Affiliated
Group does possess are valid, binding and enforceable and are not subject to any



                                       16

<PAGE>


proceedings or claims opposing the issuance, development or use thereof or
contesting the validity thereof, except to the extent that any invalidity,

         13.21    SUBORDINATION

Borrower Affiliated Group under any of the Loan Documents, all present and
future claims of any member of the Borrower Affiliated Group against any other

not arising under any of the Loan Documents), and any moneys received, after a
demand by the Bank for repayment of any of the Credit Facilities or the
occurrence of an Event of Default, by any member of the Borrower Affiliated
Group in respect thereof shall be received for the benefit of and shall be

14.      EVENTS OF DEFAULT

         The occurrence of any one or more of the following events shall

         14.1     PAYMENT

         If the Borrower defaults in the payment to the Bank of any principal,
interest, fees, costs or expenses required to be made under any of the Loan

Group and the Bank with or without notice on the part of the Bank.

ordinary course, its business, as carried on at the date hereof, or a
substantial part thereof, or if a resolution is passed or an order made for the
winding-up, liquidation or dissolution of such member of the Borrower Affiliated
Group, or if such member of the Borrower Affiliated Group makes an assignment or
proposal, or files a notice of


                                       24


<PAGE>


proposal, for the benefit of its creditors or a petition in bankruptcy is
presented against it, or if such member of the Borrower Affiliated Group
becomes subject to any other insolvency legislation.

         14.3     DEFAULT IN OTHER INDEBTEDNESS

         If the Borrower defaults under the terms of any other writing or
agreement evidencing indebtedness for borrowed money and the creditor thereof
exercises a right of acceleration and demands the immediate payment by the
Borrower of such indebtedness prior to its scheduled maturity.

         14.4     DEFAULT UNDER STOCKER & YALE CREDIT AGREEMENT

         If an event of default has occurred and is continuing under the Stocker
& Yale Credit Agreement.

         14.5     TERMINATION OF GUARANTEE

         If the Bank receives from any present or future guarantor of the
Borrower's indebtedness to the Bank hereunder or otherwise a notice purporting
to terminate or limit such guarantor's liability under its guarantee.

         14.6     MISREPRESENTATIONS OR MATERIAL ADVERSE CHANGES

         If the Bank at any time discovers that any statement, representation or
warranty herein or in any document delivered to the Bank pursuant to any of the
Loan Documents is false or misleading in any material respect; or if there is
any material adverse event or change in the financial condition or business
operations and activities of any member of the Borrower Affiliated Group, or
their respective subsidiaries or controlling affiliates which, in the aggregate
or on a consolidated basis, constitutes, in the reasonable opinion of the Bank,
a serious and substantial deterioration in the financial condition or prospects
of any member of the Borrower Affiliated Group which impairs or is likely to
impair the ability of any member of the Borrower Affiliated Group to satisfy and
perform, on a timely basis, its liabilities and obligations under any of the
Loan Documents, and such situation has not been remedied, or adequate remedial
action commenced, to the reasonable satisfaction of the Bank within 15 days
after written notice thereof by the Bank to the relevant member of the Borrower
Affiliated Group.

         14.7     CHANGE OF CONTROL

         If the effective control of any member of the Borrower Affiliated
Group, other than Stocker & Yale, directly or indirectly passes to persons or
interests other than its present controlling shareholders without the Bank's
prior written consent, which consent shall not be unreasonably withheld.

         14.8     TERMINATION OF CREDIT FACILITIES

         If in virtue of a right, privilege or option afforded to the Bank by
contract, by law or otherwise, the Bank, by written notice, validly demands
payment of the principal amount outstanding


                                       25

<PAGE>



from time to time under any other loan or credit facility which the Bank has
extended or may extend to any member of the Borrower Affiliated Group or their
respective subsidiaries, and such payment is not made within the time allowed or
stipulated in such notice.

         14.9     DEFAULT IN OTHER COVENANTS

         If any member of the Borrower Affiliated Group defaults in the
observance or performance of any other covenant or condition contained in any of
the Loan Documents and such default has not been remedied, or adequate remedial
action commenced, to the reasonable satisfaction of the Bank within 15 days
after written notice specifying such default has been given to any relevant
member of the Borrower Affiliated Group by the Bank, or if any security now or
hereafter granted by any member of the Borrower Affiliated Group in favour or
for the benefit of the Bank and securing any of the Credit Facilities, becomes
enforceable pursuant to the terms thereof.

15.      REMEDIES

         Upon the occurrence of any Event of Default hereunder, the Bank may,
without limiting any other rights of the Bank set out in any of the Loan
Documents, forthwith upon notice to the Borrower, terminate any commitment to
lend further sums or grant further credits to the Borrower hereunder or
otherwise, and declare accrued and unpaid interest on the unpaid balance of any
of the Credit Facilities immediately due and payable, whereupon it shall be due
and payable, and the Bank may exercise any and all rights, remedies, powers and
privileges afforded by the laws of the Province of Quebec or of any other
jurisdiction, or by any and all other instruments, documents and agreements
securing the payment and performance of the obligations of the Borrower
hereunder. Should the Bank incur breakage costs in connection with the early
termination (other than in accordance with the terms hereof) of any outstanding
portion of any of the Credit Facilities, such costs will be added to the
indebtedness of the Borrower to the Bank hereunder. Each member of the Borrower
Affiliated Group shall be "en demeure" to fulfill its obligations under the Loan
Documents to which it is a party by the mere lapse of time, or may be put "en
demeure" by any other method provided by law. For greater certainty, each member
of the Borrower Affiliated Group acknowledges that the occurrence of a Default
or an Event of Default is not a necessary precondition for the Bank to demand
the repayment of any of the Credit Facilities and interest thereon in accordance
with Section 4 nor to cancel, in whole or in part, the Operating Available
Commitment in accordance with Section 9.2.

16.      WAIVERS

         The acceptance by the Bank, after a Default or the occurrence of an
Event of Default, of payment of any sum owing hereunder, or the exercise by the
Bank of any right, recourse or remedy herein or otherwise provided, shall not in
itself constitute a waiver of such default nor preclude the Bank from exercising
any other right, recourse or remedy.

       No failure or delay on the part of the Bank in exercising any power or
right under any of the Loan Documents shall operate as a waiver thereof nor
shall any single or partial exercise of any such right or power preclude any
other or further exercise thereof, nor the exercise of any other right or power
hereunder. No modification or waiver of any provision of any of the Loan
Documents shall in any event be effective


                                       26


<PAGE>


unless the same shall be in writing and then such waiver shall be effective only
in the specific instance and for the purpose for which given. No notice or
demand on any member of the Borrower Affiliated Group in any case shall, of
itself, entitle any member of the Borrower Affiliated Group to any other or
further notice or demand in similar or further circumstances.

17.      CUMULATIVE REMEDIES

         The rights and remedies provided to the Bank under any of the Loan
Documents are cumulative and are in addition to and not in substitution for any
other rights and remedies which the Bank may have under the laws of the Province
of Quebec or of any other jurisdiction, and the exercise by the Bank of any
right or remedy arising from a default or breach of any undertaking, covenant or
obligation contained in any of the Loan Documents shall not be deemed to be a
waiver of or to alter, affect or prejudice any other right or remedy to which
the Bank may be lawfully entitled for the same default or breach.

18.      NOTICES

         Any notice, direction or other document required or permitted to be
given under the provisions hereof shall be in writing and may be given by
delivering, mailing or sending same by telegram, telecopier or other similar
form of communication addressed to the Bank or to the relevant member of the
Borrower Affiliated Group, at its address set forth in Appendix I hereof.

         Any notice, direction or document aforesaid, shall if delivered, be
deemed to have been given on the Business Day it was so delivered, if sent by
telegram, telecopier or other similar form of communication, be deemed to have
been given on the Business Day following the day it was so sent, and if mailed,
be deemed to have been given on the third Business Day following the day on
which it was so mailed. Any party may give written notice of a change of address
in the same manner, in which event any such communication shall thereafter be
given to it as above provided at such new address. In the event of interruption,
for any reason, of one or more of the forms of communications listed above, the
parties shall use a form which is not so interrupted with the intent that the
addressee receives timely notice of the communication.

19.      ENTIRETY AND AMENDMENTS

         This Agreement supersedes all prior commitments, agreements and
understandings, if any, relating to the subject matter hereof, but only to the
extent that they would be incompatible with or contrary to the express
provisions hereof, and this Agreement may be amended only by an instrument in
writing executed jointly by the Borrower and the Bank, and supplemented only by
documents delivered or to be delivered in accordance with the express terms
thereof.

20.      PARTIES BOUND

         This Agreement shall be binding upon and shall inure to the benefit of
each member of the Borrower Affiliated Group and the Bank and their respective
successors and assigns; provided, however, that no member of the Borrower
Affiliated Group may, without the prior written consent of the Bank, assign or
purport to assign, directly or indirectly, any of its rights, duties or
obligations under any of the Loan Documents.


                                       27

financial interests herein and in the security held in support hereof from time
to time, to one or more other financial institutions without the prior consent
of any member of the Borrower Affiliated Group. Any assignee shall be entitled
to the full benefit hereof and of the other Loan Documents and other documents
contemplated by this Agreement and shall be subject to the obligations herein to
the same extent as if it were an original party in respect of the rights or
obligations assigned to it and the Bank shall be released and discharged
accordingly and to the same extent.

21.      INTERPRETATION

         This Agreement shall be interpreted in accordance with and governed by
the laws of the Province of Quebec and the laws of Canada applicable therein.

non-exclusive jurisdiction of the courts of the Province of Quebec in respect of
any legal action or proceeding arising out of or relating to any of the Loan
Documents.

22.      MISCELLANEOUS

         22.1     EXPENSES

professional fees or expenses, and any fees or expenses associated with any
travel or other costs relating to any appraisals or examinations conducted in
connection with any of the Credit Facilities.

         22.2     INDEMNIFICATION

         The Borrower shall absolutely and unconditionally indemnify and hold
harmless the Bank against any and all claims, demands, suits, actions, causes of
action, damages, losses, settlement payments, obligations, costs, expenses and
all other liabilities whatsoever which shall at any time or times be incurred or
sustained by the Bank or by any of their shareholders, directors, officers,
employees, subsidiaries, affiliates or agents (other than as a result of the
gross or intentional fault of the Bank) on account of, or in relation to, or in
any way in connection with, any of the arrangements or transactions contemplated
by, associated with or ancillary to either the Loan Documents, whether or not
all or any of the transactions contemplated by, associated with or ancillary to
the Loan Documents, are ultimately consummated. The obligation under this
Section shall survive even after the termination of this Agreement if the cause
of action originated prior to such termination.

"DEBTOR" and collectively, the "DEBTORS") of all the Debtors' present and future
indebtedness and liabilities to the Bank, direct or indirect, actual or
contingent, in principal, interest or otherwise and any other amount for which
any of the Debtors is or may become liable to the Bank, whether at maturity or
by acceleration or otherwise under the Loan Documents, as defined below, and
under that certain letter agreement dated April 22, 1998 between the Bank and
Lasiris, as accepted by Lasiris in April, 1998 (collectively, the
"OBLIGATIONS"), the whole in accordance with the following provisions:

1. The liability of the undersigned under this Guarantee shall be solidary with
the Debtors and with any co-sureties, the undersigned expressly waiving all
benefits of division and discussion.

2. The undersigned acknowledges and confirms that this Guarantee does not fall
within the scope of Article 2362 of the CIVIL CODE OF QUEBEC. However, in the
event that such Article were found to be applicable to this Guarantee, then the
following provisions shall apply:

2.1      the notice of termination therein referred to shall be considered
         sufficient only if it is given in writing to the Bank and to all others
         concerned at least 30 days prior to the proposed effective date of
         termination; and

2.2      upon receipt by the Bank of any such notice (a) the undersigned shall
         immediately lose the benefit of the term inasmuch as it could claim any
         such benefit, and (b) the Bank may thereupon demand from the
         undersigned the immediate payment of the Obligations or any part
         thereof and to the extent that the underlying indebtedness of any of
         the Debtors is not yet due and payable, it shall be deemed accelerated
         and, as against the undersigned, shall be immediately exigible.

3. Notwithstanding any law or usage to the contrary, none of the following shall
have the effect of limiting or lessening the liability of the undersigned under
this Guarantee:

3.1      Any change in the legal status of the undersigned, any of the Debtors
         or the Bank, or its amalgamation with one or more other entities, or
         the winding-up, bankruptcy or insolvency of any of the Debtors or any
         co-surety.

3.2      Any misdescription or change in the name of the undersigned, any of the
         Debtors or the Bank.

3.3      The absence of Obligations at any particular time or any fluctuations
         in the level of the Obligations from time to time without the prior
         knowledge or consent of the undersigned.

3.4      Any partial or complete novation of the Obligations or any other cause
         of extinction of the Obligations, except (but subject to the preceding
         paragraph) the full and complete payment thereof validly made.

3.5      Any loss of security or any discharge or extinction by the Bank of
         security or suretyships in respect of the Obligations except as a
         result of the Bank's own intentional or gross fault.

3.6      Any irregularity or defect of form or substance, any incapacity,
         disability, absence or limitation of status or power of any of the
         Debtors or of the undersigned or their respective representatives.

3.7      The fact that the undersigned may or may not as of the date hereof or
         may hereafter have or cease to have, with or without the knowledge of
         the Bank, business dealings with any of the Debtors or be a
         shareholder, security holder, affiliate, associate or be in any other
         way related with any of the Debtors or any co-surety or have any other
         interest therein.

3.8      The fact that the Bank may have, in its entire discretion and without
         the prior knowledge or consent of the undersigned,

         (a)      obtained from any of the Debtors or any other person any
                  security or suretyship, or failed to obtain such security or
                  suretyship;

         (b)      waived or released in whole or in part, with or without
                  consideration, any security or suretyship held by it;

         (c)      neglected or failed to realize in whole or in part any
                  security or suretyship held by it, or neglected or failed to
                  operate or allege any right of compensation or set-off;

         (d)      accepted or failed to obtain any renewal of notes or other
                  evidences of indebtedness;

         (e)      granted or refused any delay for payment;

         (f)      made with any of the Debtors or any other person responsible
                  with or for it any composition or arrangement;

         (g)      changed the terms of repayment, the interest rate or any other
                  covenant in respect of the Obligations unless such change has
                  the effect of reducing the Obligations;

         (h)      applied any amount received on any other debt of any of the
                  Debtors, even on a debt which was not then payable, guaranteed
                  or secured;

         (i)      terminated for any reason any credit facility or credit
                  commitment granted to any of the Debtors;

         (j)      reduced or increased any of the Debtors' credit to any amount
                  or allowed the creation of overdrafts.

4. All present and future claims of the undersigned against the Debtors and all
securities, if any, relating thereto are hereby fully subordinated and postponed
by the undersigned to the present and future claims of the Bank against any of
the Debtors (including claims, if any, not covered by this Guarantee).

5. The undersigned shall refrain from exercising any benefit of subrogation in
the rights and security of the Bank until the Bank's claims against the Debtors
(including claims, if any, not covered by this Guarantee) have been fully paid,
and the Bank shall have priority over the undersigned on all assets of any of
the Debtors or of any co-surety in all circumstances, including, but without
limitation, a liquidation or the sale of an enterprise.

6. Notwithstanding Article 2366 of the CIVIL CODE OF QUEBEC, should the Bank be
obligated by any bankruptcy or other law to repay or reconvey to any of the
Debtors or any of its creditors, or to any trustee, receiver or other
representative thereof, an amount previously paid or property previously
conveyed to the Bank by or on behalf of any of the Debtors, then this Guarantee
shall be reinstated with respect to the amount of the Obligations satisfied by
such payment or conveyance before it was caused to be returned. The Bank shall
not be required to litigate or otherwise


                                       2

<PAGE>



dispute its obligation to make such repayment or reconveyance if it believes in
good faith that such obligation exists.

7. The undersigned undertakes to pay to the Bank without asserting any right of
compensation or set-off (which rights are expressly waived by the undersigned)
the full amount of the undersigned's indebtedness and liabilities hereunder
forthwith upon demand made in writing by the Bank which shall be deemed validly
made if sent by ordinary mail at the last address of the undersigned known to
the Bank, and which notice shall be deemed to have been received by the
undersigned on the third day following its date of mailing. From and after the
date of such notice, the amount claimed by the Bank from the undersigned
hereunder shall bear interest at the rate applicable to the Obligations from
time to time. The costs and expenses recoverable by the Bank from the
undersigned hereunder shall include in particular all expenses which the Bank
may incur in respect of the collection, by way of legal proceedings or
otherwise, of its claim against any of the Debtors or the undersigned.

8. The Bank is authorized (but with no obligation on its part to do so) to
set-off from any sum owed by the Bank to the undersigned, any amount in respect
of which the undersigned has agreed to become obligated to the Bank hereunder in
principal, interest or otherwise.

9. If, for the purpose of obtaining judgment in any court, it is necessary to
convert any sum due hereunder in a foreign currency into Canadian Dollars, the
rate of exchange used shall be that which in accordance with normal banking
procedures, the Bank could purchase such foreign currency with Canadian Dollars
on the business day preceding that on which a final judgment is rendered. The
obligation of the undersigned in respect of any such sum due to the Bank
hereunder shall, notwithstanding any judgment in Canadian Dollars, be discharged
only to the extent that on the business day following receipt by the Bank of any
sum adjudged to be so due in Canadian Dollars, the Bank may, in accordance with
normal banking procedures, purchase such foreign currency with Canadian Dollars;
if the foreign currency so purchased is less than the sum originally due to the
Bank in such foreign currency, the undersigned agrees, as a separate obligation
and notwithstanding any judgment, to indemnify the Bank against such loss, and
if the foreign currency so purchased exceeds the sum originally due to the Bank
in such foreign currency, the Bank shall, to the extent that all actual or
contingent liabilities and obligations of the undersigned to the Bank hereunder
or otherwise have been discharged or duly provided for, remit such excess to the
undersigned or its assigns.

10. All payments under this guarantee shall be made free and clear of all taxes,
levies, imposts, assessments, duties, charges, fees, restrictions and other
payments and conditions. If any such taxes, levies, imposts, assessments,
duties, charges, fees, restrictions or other payments or conditions are so
levied or imposed, the undersigned will (a) make additional payments in such
amounts so that every net payment of all amounts payable by it under this
Guarantee, after withholding or deduction for or on account of any such present
or future taxes, levies, imposts, assessments, duties, charges, fees,
restrictions or other payments or conditions (including any tax imposed on or
measured by net income of the Bank attributable to payments made to or on behalf
of the Bank pursuant to this Section 10 and any penalties or interest
attributable to such payments), will not be less than the amount provided for
herein or therein absent such withholding or deduction, (b) make such
withholding or deduction, and (c) remit the full amount deducted or withheld to
the relevant governmental authority in accordance with applicable law.

11. This Guarantee shall be construed in accordance with the laws of Quebec and
the undersigned agrees that any lawsuit, action or proceeding arising out of or
relating to this Guarantee may be instituted in the courts of such Province, and
the undersigned accepts and irrevocably submits to the jurisdiction of the said
courts and acknowledges their competence and agrees to be bound by any judgment
thereof; provided that nothing herein shall limit the Bank's rights to bring
proceedings against the undersigned elsewhere. The undersigned irrevocably
consents to the service of any and all process in such litigation by the mailing
of copies of such process to the undersigned at its address for notices
specified pursuant to the Credit Agreement, as amended, dated as of the date
hereof between Lasiris Inc. and the Bank (as amended, supplemented, renewed,
extended or modified from time to time, the "CREDIT AGREEMENT") or by personal
service within or without the Province of Quebec in a manner permitted by the
laws of such province. The undersigned hereby expressly and irrevocably waives,
to the fullest extent permitted by applicable law, any objection which it may
have or hereafter may have to the laying of venue of any such litigation brought
in any such court referred to above and any claim that any such litigation has
been brought in an inconvenient forum. To the extent that the undersigned has or
hereafter may acquire any immunity from jurisdiction of any court or from any
legal


                                       3

process (whether through service or notice, attachment prior to judgment,
attachment in aid of execution or otherwise) with respect to itself or its
property, the undersigned hereby irrevocably waives such immunity in respect of
its obligations under this Guarantee.

12. This Guarantee shall be binding on the undersigned and its successors and
assigns and shall inure to the benefit of the Bank and its successors and
assigns.

13. To the extent not prohibited by applicable law which cannot be waived, the
undersigned hereby knowingly, voluntarily and intentionally waives any rights it
may have to a trial by jury in respect of any litigation based hereon, or
arising out of, under, or in connection with, this Guarantee, or any of the
other Loan Documents, as defined in the Credit Agreement (the "LOAN DOCUMENTS"),
or any course of conduct, course of dealing, statements (whether verbal or
written) or actions of the Bank or of the undersigned in respect thereof. The
undersigned acknowledges and agrees that it has received full and sufficient
consideration for this provision (and each other provision of this Guarantee)
and that this provision is a material inducement for the Bank entering into the
Loan Documents to which it is a party. The undersigned acknowledges that it has
been informed by the Bank that the provisions of this Section 13 constitute a
material inducement upon which the Bank has relied, is relying and will rely in
entering into this Guarantee and the other Loan Documents. The Bank or the
undersigned may file an original counterpart or a copy of this Section 13 with
any court as written evidence of the consent of the undersigned to the waiver of
their right to trial by jury.

14. THE UNDERSIGNED ACKNOWLEDGES AND CONFIRMS HAVING REQUESTED AND OBTAINED FROM
THE BANK EVERY USEFUL INFORMATION RESPECTING THE CONTENT AND THE TERMS AND
CONDITIONS OF THE OBLIGATIONS AND THE PROGRESS MADE IN THE PERFORMANCE THEREOF.

15. The undersigned confirms its express wish that this Guarantee be drawn-up in
English and declares to be satisfied therewith. LE SIGNATAIRE CONFIRME SA
VOLONTE EXPRESSE DE VOIR CE CAUTIONNEMENT REDIGE EN ANGLAIS ET S'EN DECLARE
SATISFAIT.
