                        BACOU USA, INC. AND SUBSIDIARIES
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997

                                   (UNAUDITED)

1.   BASIS OF PRESENTATION

The accompanying consolidated condensed financial statements ("financial
statements") include the accounts of Bacou USA, Inc. and its wholly-owned
subsidiaries (together the "Company"). The Company designs, manufactures and
sells personal protective equipment, including non-prescription safety
eyewear, frames for prescription eyewear, supplied air and air purifying
respirators, gas monitors, equipment for testing breathing apparatus, vision
screening equipment and laser safety eyewear.

The financial statements have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission for interim financial
information, including the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X. Accordingly, certain information and footnote disclosures
normally required in complete financial statements prepared in accordance with
generally accepted accounting principles have been condensed or omitted. In the
opinion of management these financial statements include all adjustments
necessary for a fair presentation of the results of operations for the interim
periods presented. Results of operations for interim periods may not be
indicative of results expected for a full year.

2.   ACQUISITIONS

On May 30, 1997 the Company completed its acquisition of Comasec Holdings, Inc.
(Comasec) and its wholly-owned subsidiary Survivair, Inc. (Survivair), a
manufacturer of respiratory protection products. The acquisition was effected
through merger and redemption transactions which have been accounted for as a
purchase of all of the outstanding common stock of Comasec for $27.4 million
in cash, subject to certain closing adjustments.

On September 30, 1997 the Company completed its acquisition of Biosystems, Inc.
(Biosystems), a manufacturer of gas monitors and equipment for testing
breathing apparatus. The Company acquired all of the outstanding common stock
of Biosystems for an initial price of approximately $13.5 million, subject to
certain closing adjustments, and payable in common stock of the Company. On
September 30, 1997 the Company issued 850,000 shares of its common stock,
having a fair value on that date of approximately $13.9 million, in connection
with the acquisition of Biosystems. These shares will be held in escrow until a
final determination of all closing adjustments is made. Shares equal to 70
percent of the total shares issued in connection with the acquisition of
Biosystems are subject to a put option. The put option is exercisable at any
time within 24 months following the closing date at a price equal to
approximately $16 3/8 per share. In addition to the initial price, the Company
may be obligated to pay additional amounts if the operating results of
Biosystems in the year 2000 exceed certain defined thresholds. Additional
payments, if any, are payable in common shares of the Company, except that the
sellers may elect to receive up to $12.0 million in cash.

In accordance with generally accepted accounting principles, the cash paid and
fair value of common stock issued to effect these acquisitions has been
allocated to the fair value of assets purchased and liabilities assumed. In each
case, the excess of acquisition price over fair value of net assets acquired has
been recorded as goodwill and is being amortized over 40 years. Amounts recorded
as goodwill are subject to change based on the resolution of various
outstanding closing adjustments and in the case of Biosystems, as a result of
additional payments that may be made if operating results in the year 2000
exceed defined thresholds. The fair value of purchased in-process research and
development was $1.3 million for Survivair and $2.4 million for Biosystems and
has been charged to operating expenses at the respective dates of acquisition.
The purchase price for these acquisitions has been allocated approximately as
shown in the following table.

</TABLE>
                          

The acquisitions have been accounted for as purchases and, accordingly,
operating results of the acquired companies have been included in the
accompanying financial statements of the Company beginning with the respective
acquisition dates. The following table presents pro forma results of operations
of the Company as if these acquisitions had occurred as of January 1, 1996 (in
thousands). The pro forma operating results include results of operations for
the indicated periods with adjusted depreciation on property and equipment,
increased amortization of intangible assets, assumed interest expense on the
cash purchase price, and increased weighted shares outstanding for shares issued
in connection with the acquisitions. Non-recurring charges resulting from the
acquisitions have been excluded from the pro forma results. The pro forma
information given does not purport to be indicative of the results that actually
would have been obtained if the operations were combined during the periods
presented and is not intended to be a projection of future results or trends.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS



FACTORS THAT MAY AFFECT FUTURE PERFORMANCE

Statements contained in this Form 10-Q that are not historical facts are
forward-looking statements that are made pursuant to the safe harbor provisions
of the Private Securities Litigation Reform Act of 1995. In addition, when used
in this Form 10-Q, words such as "believes," "anticipates," "expects," and
similar expressions are intended to identify forward-looking statements. The
Company cautions that a number of important factors could cause actual outcomes
to differ materially from those expressed in any forward-looking statements made
by, or on behalf of, the Company. Forward-looking statements involve a number
of risks and uncertainties including, but not limited to, continued demand for
current product lines, the success of new product introductions, continued
availability and favorable pricing of raw materials, the effect of any work
stoppages, the success of the Company's acquisition strategy, competitive
pressures, general economic conditions, and regulatory matters. The Company
cannot assure that it will be able to anticipate or respond timely to changes
in any of the factors listed above, which could adversely affect the operating
results in one or more fiscal quarters. Results of operations in any past
period should not be considered indicative of the results to be expected for
future periods. Fluctuations in operating results may also result in
fluctuations in the price of the Company's common stock.

ACQUISITIONS

The Company acquired all of the outstanding capital stock of Comasec on May 30,
1997. The assets of Comasec consisted primarily of its wholly-owned subsidiary
Survivair, a manufacturer of respiratory protection products. The acquisition
was effected through merger and redemption transactions which have been
accounted for as a purchase of all of the outstanding common stock of Comasec
for $27.4 million in cash, subject to certain closing adjustments. Operating
results of Survivair have been included in the financial statements of the
Company beginning June 1, 1997.

The Company also acquired all of the capital stock of Biosystems, a manufacturer
of gas monitors and equipment for testing breathing apparatus, on September 30,
1997. The initial acquisition price was approximately $13.5 million payable in
common stock of the Company and is subject to certain closing adjustments. The
initial acquisition price may be increased if the operating results of
Biosystems in the year 2000 exceed certain defined thresholds. Except for the
non-recurring charge for purchased in-process research and development which
were recorded on September 30, 1997, operating results of Biosystems will be
included in the financial statements of the Company beginning October 1, 1997.

     Net Sales. Net sales increased 21.9% from $29.3 million for the three
months ended September 30, 1996 to $35.7 million for the three months ended
September 30, 1997. Net sales for the 1997 period included sales for Survivair
of $6.4 million, accounting for the increase in total sales for the quarter.
Excluding sales of discontinued product lines, net sales increased by 25.3% from
$28.4 million in the 1996 period to $35.6 million in the 1997 period.

     Export sales represented 11.5% of net sales in the 1997 period and 6.5% of
net sales in the 1996 period, increasing by 115.0% from 1996 to 1997. Export
sales for the 1997 period included export sales for Survivair of $1.2 million.

     Cost of Sales. Cost of sales increased 44.3% from $12.4 million for the
three months ended September 30, 1996 to $17.9 million for the three months
ended September 30, 1997 primarily as a result of the acquisition of Survivair.

     Gross Profit. Gross profit increased 5.4% from $16.9 million for the three
months ended September 30, 1996 to $17.8 million for the three months ended
September 30, 1997. As a percentage of sales, gross profit was 49.8% in the 1997
period and 57.6% in the 1996 period. The Company's gross margin declined from
the 1996 period to the 1997 period primarily due to the acquisition of
Survivair. The gross margin of Survivair is lower than the combined gross margin
of the Company's other subsidiaries. In addition, acquisition-related charges
reduced gross profit by approximately $775,000 during the third quarter of 1997.
Excluding these charges, gross margin for the 1997 period would have been 52.0%.
Acquisition-related charges relating to Biosystems will reduce gross profit for
the fourth quarter of 1997 by approximately $400,000.

    Operating Expenses. The acquisition of Biosystems has been accounted
for as a purchase and accordingly, the purchase price has been allocated to the
fair value of assets purchased and liabilities assumed. This allocation
included the fair value of in-process research and development equal to $2.4
million. Accordingly, a non-recurring charge for purchased in-process research
and development of Biosystems, in the amount of $2.4 million, was recorded in
the 1997 period. Operating expenses, excluding the non-recurring charge and
excluding amortization expense, increased from $6.9 million for the three
months ended September 30, 1996 to $8.8 million for the three months ended
September 30, 1997, primarily as a result of the acquisition of Survivair.
Amortization of intangible assets for the 1997 period was essentially unchanged
compared with the 1996 period, however, is expected to increase by
approximately $400,000 on an annual basis as a result of the Biosystems
acquisition.

     Operating Income. As a result of the foregoing, the Company's operating
income declined from $9.0 million for the three months ended September 30, 1996
to $5.5 million for the three months ended September 30, 1997.

     Income Taxes. The Company's effective income tax rate was 54.3% in the 1997
period and 38.5% in the 1996 period. The effective rate was higher than the
federal statutory rate of 35.0% due to state and local income taxes and, in the
1997 period, because a tax benefit cannot be recorded for the non-recurring
charge equal to $2.4 million for the purchase of in-process research and
development of Biosystems.

                                        9

     Net Income. As a result of the foregoing, the Company's net income totaled
$2.5 million in the 1997 period and $5.7 million in the 1996 period. Excluding
the effect of non-recurring acquisition-related adjustments, the Company's net
income would have been $5.4 million in the 1997 period compared with $5.7
million in the 1996 period.

Net Sales. Net sales increased 11.9% from $84.4 million for the nine months
ended September 30, 1996 to $94.4 million for the nine months ended September
30, 1997. Net sales for the 1997 period include sales for Survivair of $8.8
million. There were no sales for Survivair included for the 1996 period.
Excluding sales of discontinued product lines, net sales increased by 16.2% from
$80.9 million in the 1996 period to $94.1 million in the 1997 period.

Export sales represented 11.0% of net sales in the 1997 period and 7.0% of net
sales in the 1996 period, increasing by 75.7% from 1996 to 1997.

Cost of Sales. Cost of sales increased 24.2% from $36.4 million for the nine
months ended September 30, 1996 to $45.2 million for the nine months ended
September 30, 1997. The increase was primarily attributable to the acquisition
of Survivair as well as higher production costs at Titmus Optical, Inc. (Titmus)
during the first quarter of 1997.

Gross Profit. Gross profit increased from $48.0 million for the nine months
ended September 30, 1996 to $49.3 million for the nine months ended September
30, 1997. As a percentage of net sales, gross profit was 52.2% for the 1997
period and 56.9% for the 1996 period. The Company's gross margin declined from
the 1996 period to the 1997 period as a result of lower gross margins at
Survivair, acquisition - related charges at Survivair totaling approximately
$1.3 million, and higher production costs during the first quarter of 1997 at
Titmus. Excluding the acquisition-related charge, the Company's gross margin for
the 1997 period would have been 53.6%.

                                       10

Operating Expenses. The Company has recorded during the 1997 period
non-recurring charges equal to $3.7 million in the aggregate for purchased
in-process research and development of Survivair and Biosystems. Operating
expenses, excluding non-recurring charges and amortization expense, increased
from $19.4 million for the nine months ended September 30, 1996 to $23.5 million
for the nine months ended September 30, 1997. This increase was primarily the
result of the acquisition of Survivair as well as additional advertising and
marketing costs in the 1997 period.

Operating Income. As a result of the foregoing, the Company's operating income
declined from $25.5 million for the nine months ended September 30, 1996 to
$19.1 million for the nine months ended September 30, 1997.

Other Expense (Income). Other expense (income) was $0.3 million and $(0.5)
million for the nine months ended September 30, 1996 and 1997, respectively.
The Company had outstanding indebtedness totaling $49.0 million at January 1,
1996. This indebtedness was fully repaid by April 1996, primarily with proceeds
from the Company's initial public offering. The Company has had lower levels of
debt outstanding during the 1997 period, and the change in other expense
(income) is primarily due to a decline in net interest expense from 1996 to
1997.

Income Taxes. The Company's effective income tax rate was 44.8% during the 1997
period and 38.7% during the 1996 period. The effective rate was higher than the
federal statutory rate due to state and local taxes and, in the 1997 period,
because a tax benefit cannot be recorded for non-recurring charges equal to $3.7
million for the purchase of in-process research and development of Survivair and
Biosystems.

Net Income. As a result of the foregoing, the Company's net income declined from
$15.4 million for the nine months ended September 30, 1996 to $10.8 million for
the nine months ended September 30, 1997. Excluding the effect of non-recurring
acquisition-related adjustments, the Company's net income would have been $15.4
million in both the i997 and 1996 periods.

LIQUIDITY AND CAPITAL RESOURCES

     Gross cash flow (net income plus non-cash items) totaled $20.9 million
during the 1997 period and $21.8 million during the 1996 period. Earnings before
interest, taxes, depreciation and amortization (EBITDA) and before non-recurring
acquisition-related charges totaled $30.5 million during the 1997 period and
$31.3 million during the 1996 period.

     Excluding trade accounts receivable acquired in connection with the
Survivair and Biosystems acquisitions, the Company's trade accounts receivable
increased from $10.5 million at December 31, 1996 to $13.9 million at September
30, 1997. This increase resulted primarily from sales volume during the third
quarter of 1997 that exceeded sales volume during the fourth quarter of 1996.
Inventories increased from $17.5 million at December 31, 1996 to $24.9 million
at September 30, 1997 entirely as a result of the acquisitions of Survivair and
Biosystems.

     Cash used in investing activities totaled $31.4 million in the 1997 period
compared with $7.4 million in the 1996 period. The 1997 period includes $27.9
million expended for the acquisition of businesses, principally in connection
with the Survivair acquisition. Capital expenditures totaled $3.5 million in the
1997 period and $7.4 million in the 1996 period.

     The acquisition of Survivair was financed principally from available cash
balances. The Company borrowed $8.0 million in connection with the acquisition
of Survivair under a term note. This borrowing was repaid in full during the
second quarter of 1997, in part from proceeds from a revolving line of credit.

     Effective May 21, 1997 the Company closed on a $28.0 million Revolving Line
of Credit (the "Revolving Facility") with Citizens Bank of Rhode Island
("Citizens"). The Revolving Facility is available to fund future acquisitions
and for other general corporate purposes. Principal outstanding under the
Revolving Facility is due in full on April 30, 1998 and bears interest at the
rate per annum equal to LIBOR plus 0.7%. The Revolving Facility is subject to
annual renewal and is also subject to various covenants including a covenant to
maintain a ratio of liabilities to tangible net worth of not more than 1.0:1.0.
Principal outstanding totaled $7.2 million at September 30, 1997. Biosystems
maintained a line of credit facility which was terminated in October 1997 and
all outstanding principal ($1.2 million at September 30, 1997) was repaid
through advances under the Revolving Facility.

                                       11


<PAGE>   12



     The Company also maintains a $3.0 million revolving line of credit which is
available for use by a wholly-owned subsidiary for its general working capital
purposes. Significant terms and conditions relating to this facility are
consistent with terms and conditions of the Revolving Facility. There were no
principal amounts outstanding under this facility at September 30, 1997.

     During the third quarter of 1997 the Company purchased 554,000 unregistered
shares in a privately negotiated transaction from a non-affiliated corporate
investor at a purchase price of $14.50 per share, or a total of $8,038,800.
These shares were held in treasury at September 30, 1997; however, in October
1997 the Board of Directors voted to retire and cancel these shares. Effective
September 30, 1997 the Board of Directors also authorized an open market buyback
program to purchase up to 300,000 shares of the Company's common stock. As of
November 14, 1997 no shares had been purchased under this program.

     In connection with the Biosystems acquisition, the Company provided selling
shareholders with a put option covering 70 percent of the shares (currently
estimated to be 595,000 shares) issued in connection with that acquisition. The
put options may be exercised within 24 months following the acquisition date at
a price approximately equal to $16 3/8 per share. If the put options were
exercised in full, the Company would be obligated to repurchase shares at a
value totaling approximately $9,730,000.

     The Company believes that cash flow from operations together with available
borrowing capacity are sufficient to fund working capital requirements, debt
service requirements, and capital expenditures for the foreseeable future. The
Company pursues a business strategy which includes acquisitions as an important
element. The Company may incur additional indebtedness, may be required to
negotiate additional credit facilities, or may issue additional common stock in
order to fund investments, if any, resulting from its acquisition strategy.

SEASONALITY

The Company's business has been subject to slight seasonal variations which the
Company has attributed to fluctuations in industrial activity and annual weather
patterns. Historically, net sales from October through December have been
somewhat lower than other periods due to anticipated lower demand in the more
inclement winter months and planned inventory reductions by major distributors.
In addition to seasonality, the Company's business has been variable period to
period due to other factors, including promotional activity undertaken by the
Company in response to competitive pressures, market demand, production
capacity, inventory levels, and other considerations.

NEW ACCOUNTING PRONOUNCEMENTS

Statement of Financial Accounting Standard No. 128, "Earnings Per Share,"
(Statement 128) was issued in February 1997. Statement 128 requires dual
presentation of basic earnings per share and diluted earnings per share, and
supersedes previously issued accounting principles concerning determination and
disclosure of earnings per share. The Company is required to adopt the
provisions of Statement 128 for the year ended December 31, 1997; however, these
provisions may not be adopted for interim financial statements issued prior to
December 31, 1997. The Company does not believe Statement 128 will have a
significant impact on the determination of its 1997 earnings per share when the
related provisions are adopted.

Statement of Financial Accounting Standard No. 131, "Disclosures about Segments
of an Enterprise and Related Information," (Statement 131) was issued in June
1997. Statement 131 requires disclosure of financial and descriptive information
about reportable operating segments, and supersedes previously issued accounting
principles concerning segment reporting. The Company is required to adopt the
provisions of Statement 131 for periods beginning after December 15, 1997
(calendar year 1998 for the Company). Statement 131 will, at most, require
certain additional disclosure in the Company's financial statements.

                              EMPLOYMENT AGREEMENT


       THIS AGREEMENT made as of this 30th day of May 1997, by and between Jack
Bell of 610 Carnation, Corona Del Mar, CA 92625 ("Executive") and Survivair,
Inc., a corporation organized under the laws of Connecticut (the "Company").

                              W I T N E S S E T H :

       WHEREAS, Bacou USA, Inc. has entered into an agreement to purchase the
company and desires to clarify the terms and conditions which Executive shall
continue to be employed by the company; and

       WHEREAS, Company wishes to secure the services of Executive as President
and Chief Executive Officer for the period provided in this Agreement; and

       WHEREAS, Executive is willing to enter into this Agreement for such
period and on the terms and conditions hereinafter set forth;

       NOW, THEREFORE, in consideration of the mutual promises herein contained,
Company and Executive hereby agree as follows:

       1.    EMPLOYMENT. During the period of employment set forth in Section 2
of this Agreement, Company shall employ Executive, and Executive shall serve as
President and Chief Executive Officer of Company. Executive agrees to faithfully
perform the duties assigned to him to the best of his ability and, except for
vacations and periods of temporary illness, to devote his full time and
attention to the business of Company. Ancillary employment such as writing,
teaching or lecturing, as well as the acceptance of honorific titles may be
undertaken by the Executive only with the approval of the Chief Executive
Officer of Bacou USA, Inc. or his designee ("Chairman"). Executive also agrees
that he will not engage in any other business activities without the prior
approval of the Chairman. Executive may only serve as an officer, director,
trustee or committee member, or in any similar position, of a reasonable number
(maximum two) of trade associations and religious, charitable, educational,
civic or other non-business organizations, subject to the approval of the
Chairman. The Executive represents and warrants to Company that he is now under
no contract or agreement nor will he execute any contract or agreement that will
in any manner interfere, conflict with or prevent him from performing his duties
under the terms and conditions of this Agreement, recognizing that his
performance hereunder will require the devotion of his full time and attention
during and beyond regular business hours during the Term (as hereinafter
defined), including extensive travel.

       2.    PERIOD OF EMPLOYMENT. This Agreement shall become effective upon
the closing of the transaction in which Bacou USA, Inc. become the direct or
indirect owner of the Company and its terms shall be retroactively applicable to
the first day of the Initial Term, as defined herein. The Executive's employment
under this Agreement shall initially cover the period January 1, 1997 to
December 31, 1998 (the "Initial Term"). On December 31, 1998, and at the end of
each year thereafter, the period of employment shall be automatically extended,
without further action by either party, for successive one year periods (each a
"Renewal Term") unless at least six months prior to the end of any Term either
party shall have served written notice on the other of its election to allow
this Agreement to terminate at the end of such Term. The Initial Term and any
Renewal Terms are hereinafter sometimes collectively referred to as the "Term."

       If either party notifies the other party that it shall not extend the
period of employment, Company may, at its option, decide that the Executive
shall take a leave-of-absence for part or all of the remaining time of his
employment, continuing to receive all compensation as if actively working.

       3.    TERMINATION. The period of employment shall be terminated upon the
first to occur of the following:

       (i)   The expiration of the period of employment pursuant to Section 2 of
             this Agreement.

       (ii)  The Executive's death.

       (iii) The Executive becoming permanently disabled. Permanent disability
             shall mean physical or mental incapacity of a nature which prevents
             Executive from performing his duties under this Agreement for a
             period of more than six months in any twelve month period.

       (iv)  The Executive's employment being terminated by Company for cause.
             Termination for cause shall mean termination by action of the Board
             of Directors of Company because of the willful failure of Executive
             to perform his duties and obligations under this Agreement or
             failure to execute in a reasonable and responsible manner the
             policies of Company or gross negligence in the performance of his
             duties under this Agreement or the commission by Executive of a
             felony.

participate in any other incentive compensation plan of the Company.

does not take all vacation days the remaining days will be carried forward for
an unlimited period or be paid to the Executive at the level of his Base Salary
valid for the fiscal year in which vacation days are not taken.

                 (iii) When traveling on Company business, the Executive will be
provided coach-class airfare on domestic trips; business class airfare will be

connected with Company's business, shall be the sole and exclusive property of
Company or its designee and the Executive, whenever requested to do so by
Company, shall, without further compensation or consideration properly execute

designee shall deem necessary in order to apply for and obtain Letters Patent of
the United States and/or comparable rights afforded by foreign countries for the

and exclusive right, title and interest in and to the Inventions. This
obligation shall continue beyond the termination of this Agreement with respect
to Inventions conceived or made by the Executive during the term of his
employment by Company, and shall be binding upon his assigns, executors,
administrators, and other legal representatives.

       8.    NON-COMPETITION. (a) During the term of this Agreement or any
renewal thereof and, at Company's option for a period of up to one year
thereafter, should the Executive's contract be terminated or not be renewed, the
Executive agrees that he will not within the geographical area of the United
States, engage, either directly or indirectly, individually or as an owner,
partner, joint venturer, employee, officer, director, stockholder, consultant,
independent contractor or lender of or to any corporation, holding Company or
other business entity which is in a business similar to that of Company or any
of its affiliates. In the event that Company chooses to exercise its option to
prevent the Executive from competing with Company following termination or
non-renewal of his employment, Company shall notify the Executive in writing
within two (2) weeks following his last day of employment or within two (2)
weeks of notice by Company of its decision that the Executive shall take a
leave-of-absence, in either case specifying the period of up to one year
following

termination, resignation, or non-renewal of employment during which such
competitive activity shall be prohibited. In the event Company exercises its
option, Company shall continue to pay Executive his Base Salary at the time of
termination, resignation or non-renewal for the period during which the
Executive is prohibited from competition with Company. Notwithstanding the
foregoing, the Executive (as hereinbefore described in Section 2(d)) may own
five (5%) percent of the securities of any business in competition with the
business of Company or any of its affiliates, which securities are regularly
traded on a public exchange, provided that any such ownership shall not result
in the Executive becoming a record or beneficial owner at any time of more than
five (5%) percent of equity securities of said business entity.

             (b) The Executive shall not during the term of his Employment under

             (c) If any provision of this Section is held to be unenforceable
because of the scope, duration or area of its applicability or otherwise, the
legal entity making that determination will have the power to modify the scope,
duration or area, or all of them, and the provision will then apply in its
modified form.

                              EMPLOYMENT AGREEMENT


       THIS AGREEMENT made as of this 30th day of May, 1997, by and between
Robert Hitchcock of 24971 Sausalito Street, Laguna Hills, CA 92653 ("Executive")
and Survivair, Inc., a corporation organized under the laws of Connecticut (the
"Company").

                              W I T N E S S E T H :

       WHEREAS, Bacou USA, Inc. has entered into an agreement to purchase the
Company and desires to clarify the terms and conditions upon which Executive
shall continue to be employed by the Company; and

       WHEREAS, Company wishes to secure the services of Executive as Vice
President - Marketing & Sales, for the period provided in this Agreement; and

       WHEREAS, Executive is willing to enter into this Agreement for such
period and on the terms and conditions hereinafter set forth;

       NOW, THEREFORE, in consideration of the mutual promises herein contained,
Company and Executive hereby agree as follows:

       1.    EMPLOYMENT. During the period of employment set forth in Section 2
of this Agreement, Company shall employ Executive, and Executive shall serve as
Vice President - Marketing & Sales of Company. Executive agrees to faithfully
perform the duties assigned to him to the best of his ability and, except for
vacations and periods of temporary illness, to devote his full time and
attention to the business of Company. Ancillary employment such as writing,
teaching or lecturing, as well as the acceptance of honorific titles may be
undertaken by the Executive only with the approval of the Chief Executive
Officer of Bacou USA, Inc. or his designee ("Chairman"). Executive also agrees
that he will not engage in any other business activities without the prior
approval of the Chairman. Executive may only serve as an officer, director,
trustee or committee member, or in any similar position, of a reasonable number
(maximum two) of trade associations and religious, charitable, educational,
civic or other non-business organizations, subject to the approval of the
Chairman. The Executive represents and warrants to Company that he is now under
no contract or agreement nor will he execute any contract or agreement that will
in any manner interfere, conflict with or prevent him from performing his duties
under the terms and conditions of this Agreement, recognizing that his
performance hereunder will require the devotion of his full time and attention
during and beyond regular business hours during the Term (as hereinafter
defined), including extensive travel.

       2.    PERIOD OF EMPLOYMENT. This Agreement shall become effective upon
the closing of the transaction in which Bacou USA, Inc. becomes the direct or
indirect owner of the Company and its terms shall be retroactively applicable to
the first day of the Initial Term, as defined herein. The Executive's employment
under this Agreement shall initially cover the period January 1, 1997 to
December 31, 1998 (the "Initial Term"). On December 31, 1998, and at the end of
each year thereafter, the period of employment shall be automatically extended,
without further action by either party, for successive one-year periods (each a
"Renewal Term") unless at least six months




<PAGE>   2

prior to the end of any Term either party shall have served written notice on
the other of its election to allow this Agreement to terminate at the end of
such Term. The Initial Term and any Renewal Terms are hereinafter sometimes
collectively referred to as the "Term."

       If either party notifies the other party that it shall not extend the
period of employment, Company may, at its option, decide that the Executive
shall take a leave-of-absence for part or all of the remaining time of his
employment, continuing to receive all compensation as if actively working.

       3.    TERMINATION. The period of employment shall be terminated upon the
first to occur of the following:

       (i)   The expiration of the period of employment pursuant to Section 2 of
             this Agreement.

       (ii)  The Executive's death.

       (iii) The Executive becoming permanently disabled. Permanent disability
             shall mean physical or mental incapacity of a nature which prevents
             Executive from performing his duties under this Agreement for a
             period of more than six months in any twelve month period.

       (iv)  The Executive's employment being terminated by Company for cause.
             Termination for cause shall mean termination by action of the Board
             of Directors of Company because of the willful failure of Executive
             to perform his duties and obligations under this Agreement or
             failure to execute in a reasonable and responsible manner the
             policies of Company or gross negligence in the performance of his
             duties under this Agreement or the commission by Executive of a
             felony.

       4.    COMPENSATION AND BENEFITS.

             (a) The Executive shall receive regular compensation (the "Base
Salary") at the initial rate per annum of One Hundred Fifty-Three Thousand Five
Hundred Twenty-Eight Dollars ($153,528.00) per annum for the period January 1 to
December 31, 1997. The Base Salary shall be payable in arrears less the usual
payroll deductions at the same times and in the same manner as salaries paid to
other employees of the Company. The Executive shall participate in any wage
increases applicable generally to salaried employees of Company. The Base Salary
prevailing at any time shall be reviewed annually for a possible increase
beginning in January 1998.

             (b) In addition to the Base Salary, the Executive shall be entitled
to receive annual incentive compensation payments ("Incentive Compensation") at
such times and in such amounts as may be determined pursuant to the Bonus Plan
for Executives of subsidiaries of Bacou USA, Inc., as in effect for the
applicable year. Executive acknowledges that, by agreeing to participate in the
Bonus Plan for subsidiaries of Bacou USA, Inc., he thereby waives any rights to
participate in any other incentive compensation plan of the Company.

does not take all vacation days the remaining days will be carried forward for
an unlimited period or be paid to the Executive at the level of his Base Salary
valid for the fiscal year in which vacation days are not taken.

                 (iii) When traveling on Company business, the Executive will be
provided coach-class airfare on domestic trips; business class airfare will be

       6.    NON-DISCLOSURE OF INFORMATION. It is understood that the business
of Company and its affiliates is of a confidential nature. During the period of
the Executive's employment with Company, the Executive may have received and/or
may secure confidential information concerning Company or any of Company's
affiliates or subsidiaries which, if known to competitors thereof, would damage
Company or its said affiliates or subsidiaries. The Executive agrees that during
and after the term of this Agreement he will not (except as authorized by
Company or in the proper performance of his duties or except as ordered by a
court or other body of competent jurisdiction or as otherwise required by law),
directly or indirectly, divulge, disclose or appropriate to his own use, or to
the use of any third party, any secret, proprietary or confidential information
or knowledge obtained by him during the term hereof concerning such confidential
matters of Company or its subsidiaries or affiliates, including, but not limited
to, information pertaining to trade secrets, systems, manuals, confidential
reports, methods, processes, designs, equipment lists, operating procedures,
equipment and methods used and preferred by Company's customers. Upon
termination of this Agreement, the Executive shall promptly deliver to Company
all materials of a secret or confidential nature relating to the business of
Company or any of its subsidiaries or affiliates which are, directly or
indirectly, in the possession or under the control of the Executive. The
provisions of this paragraph shall continue to apply after the Executive ceases
to be employed by Company for a period of three (3) years except in respect of
any information or knowledge disclosed to the public, other than through an
unauthorized disclosure by the Executive.

       7.    TRADE SECRETS. The Executive covenants that he shall, while
employed by Company, assign, transfer, and set over to Company or its designee
all right, title and interest in and to all trade secrets, secret processes,
inventions, improvements, patents, patent applications, trademarks, trademark
applications, copyrights, copyright registrations, discoveries and/or other
developments (hereinafter "Inventions") which he may, thereafter, alone or in
conjunction with others, during or outside normal working hours, conceive, make,
acquire or suggest at any time which relate to the products, processes, work,
research, or other activities of Company or any of its subsidiaries or
affiliates. Any and all Inventions which are of a proprietary nature and which
the Executive may conceive, may acquire or suggest, either alone or in
conjunction with others, during his employment with Company (whether during or
outside normal working hours) relating to or in any way pertaining to or
connected with Company's business, shall be the sole and exclusive property of
Company or its designee and the Executive, whenever requested to do so by
Company, shall, without further compensation or consideration properly execute
any and all applications, assignments or other documents which Company or its
designee shall deem necessary in order to apply for and obtain Letters Patent of
the United States and/or comparable rights afforded by foreign countries for the
Inventions, or in order to assign and convey to Company or its designee the sole
and exclusive right, title and interest in and to the Inventions. This
obligation shall continue beyond the termination of this Agreement with respect
to Inventions conceived or made by the Executive during the term of his
employment by Company, and shall be binding upon his assigns, executors,
administrators, and other legal representatives.

       8.    NON-COMPETITION. (a) During the term of this Agreement or any
renewal thereof and, at Company's option for a period of up to one year
thereafter, should the Executive's contract be terminated or not be renewed, the
Executive agrees that he will not within the geographical area of the United
States, engage, either directly or indirectly, individually or as an owner,
partner, joint venturer, employee, officer, director, stockholder, consultant,
independent contractor or lender of



                                        5

or to any corporation, holding Company or other business entity which is in a
business similar to that of Company or any of its affiliates. In the event that
Company chooses to exercise its option to prevent the Executive from competing
with Company following termination or non-renewal of his employment, Company
shall notify the Executive in writing within two (2) weeks following his last
day of employment or within two (2) weeks of notice by Company of its decision
that the Executive shall take a leave-of-absence, in either case specifying the
period of up to one year following termination, resignation, or non-renewal of
employment during which such competitive activity shall be prohibited. In the
event Company exercises its option, Company shall continue to pay Executive his
Base Salary at the time of termination, resignation or non-renewal for the
period during which the Executive is prohibited from competition with Company.
Notwithstanding the foregoing, the Executive (as hereinbefore described in
Section 2(d)) may own five (5%) percent of the securities of any business in
competition with the business of Company or any of its affiliates, which
securities are regularly traded on a public exchange, provided that any such
ownership shall not result in the Executive becoming a record or beneficial
owner at any time of more than five (5%) percent of equity securities of said
business entity.

             (b) The Executive shall not during the term of his Employment under
this Agreement or any renewal thereof, and for a period of one (3) years

or retain any person who was employed by Company or any of its affiliated
companies having an annual compensation of at least U.S. $50,000 per annum
during the term of this Agreement or any renewal thereof.

             (c) If any provision of this Section is held to be unenforceable
because of the scope, duration or area of its applicability or otherwise, the
legal entity making that determination will have the power to modify the scope,
duration or area, or all of them, and the provision will then apply in its
modified form.

       9.    PROPERTY. All letters, memoranda, documents, business notes
(including all copies thereof) and other information contained on any other
computer media including computer disks and hard drives of the Executive in any
manner relating to the duties of Executive under this agreement are the property

                              W I T N E S S E T H :

       WHEREAS, Bacou USA, Inc. has entered into an agreement to purchase the
Company and desires to clarify the terms and conditions upon which Executive
shall continue to be employed by the Company; and

       WHEREAS, Company wishes to secure the services of Executive as Vice
President - Finance for the period provided in this Agreement; and

       WHEREAS, Executive is willing to enter into this Agreement for such
period and on the terms and conditions hereinafter set forth;

       NOW, THEREFORE, in consideration of the mutual promises herein contained,
Company and Executive hereby agree as follows:

       1.    EMPLOYMENT. During the period of employment set forth in Section 2
of this Agreement, Company shall employ Executive, and Executive shall serve as
Vice President - Finance of Company. Executive agrees to faithfully perform the
duties assigned to him to the best of his ability and, except for vacations and
periods of temporary illness, to devote his full time and attention to the
business of Company. Ancillary employment such as writing, teaching or
lecturing, as well as the acceptance of honorific titles may be undertaken by
the Executive only with the approval of the Chief Executive Officer of Bacou
USA, Inc. or his designee ("Chairman"). Executive also agrees that he will not
engage in any other business activities without the prior approval of the
Chairman. Executive may only serve as an officer, director, trustee or committee
member, or in any similar position, of a reasonable number (maximum two) of
trade associations and religious, charitable, educational, civic or other
non-business organizations, subject to the approval of the Chairman. The
Executive represents and warrants to Company that he is now under no contract or
agreement nor will he execute any contract or agreement that will in any manner
interfere, conflict with or prevent him from performing his duties under the
terms and conditions of this Agreement, recognizing that his performance
hereunder will require the devotion of his full time and attention during and
beyond regular business hours during the Term (as hereinafter defined),
including extensive travel.

       2.    PERIOD OF EMPLOYMENT. This Agreement shall become effective upon
the closing of the transaction in which Bacou USA, Inc. becomes the direct or
indirect owner of the Company and its terms shall be retroactively applicable to
the first day of the Initial Term, as defined herein. The Executive's employment
under this Agreement shall initially cover the period January 1, 1997 to
December 31, 1998 (the "Initial Term"). On December 31, 1998, and at the end of
each year thereafter, the period of employment shall be automatically extended,

either party, for successive one-year periods (each a "Renewal Term") unless at
least six months prior to the end of any Term either party shall have served
written notice on the other of its election to allow this Agreement to terminate
at the end of such Term. The Initial Term and any Renewal Terms are hereinafter
sometimes collectively referred to as the "Term."

       If either party notifies the other party that it shall not extend the

of Company and its affiliates is of a confidential nature. During the period of
the Executive's employment with Company, the Executive may have received and/or
may secure confidential information concerning Company or any of Company's
affiliates or subsidiaries which, if known to competitors thereof, would damage
Company or its said affiliates or subsidiaries. The Executive agrees that during
and after the term of this Agreement he will not (except as authorized by
Company or in the proper performance of his duties or except as ordered by a
court or other body of competent jurisdiction or as otherwise required by law),
directly or indirectly, divulge, disclose or appropriate to his own use, or to
the use of any third party, any secret, proprietary or confidential information
or knowledge obtained by him during the term hereof concerning such confidential
matters of Company or its subsidiaries or affiliates, including, but not limited
to, information pertaining to trade secrets, systems, manuals, confidential
reports, methods, processes, designs, equipment lists, operating procedures,
equipment and methods used and preferred by Company's customers. Upon
termination of this Agreement, the Executive shall promptly deliver to Company
all materials of a secret or confidential nature relating to the business of
Company or any of its subsidiaries or affiliates which are, directly or
indirectly, in the possession or under the control of the Executive. The
provisions of this paragraph shall continue to apply after the Executive ceases
to be employed by Company for a period of three (3) years except in respect of
any information or knowledge disclosed to the public, other than through an
unauthorized disclosure by the Executive.

       7.    TRADE SECRETS. The Executive covenants that he shall, while
employed by Company, assign, transfer, and set over to Company or its designee
all right, title and interest in and to all trade secrets, secret processes,
inventions, improvements, patents, patent applications, trademarks, trademark
applications, copyrights, copyright registrations, discoveries and/or other
developments (hereinafter "Inventions") which he may, thereafter, alone or in
conjunction with others, during or outside normal working hours, conceive, make,
acquire or suggest at any time which relate to the products, processes, work,
research, or other activities of Company or any of its subsidiaries or
affiliates. Any and all Inventions which are of a proprietary nature and which
the Executive may conceive, may acquire or suggest, either alone or in
conjunction with others, during his employment with Company (whether during or
outside normal working hours) relating to or in any way pertaining to or
connected with Company's business, shall be the sole and exclusive property of
Company or its designee and the Executive, whenever requested to do so by
Company, shall, without further compensation or consideration properly execute
any and all applications, assignments or other documents which Company or its
designee shall deem necessary in order to apply for and obtain Letters Patent of
the United States and/or comparable rights afforded by foreign countries for the
Inventions, or in order to assign and convey to Company or its designee the sole
and exclusive right, title and interest in and to the Inventions. This
obligation shall continue beyond the termination of this Agreement with respect
to Inventions conceived or made by the Executive during the term of his
employment by Company, and shall be binding upon his assigns, executors,
administrators, and other legal representatives.

       8.    NON-COMPETITION. (a) During the term of this Agreement or any
renewal thereof and, at Company's option for a period of up to one year
thereafter, should the Executive's contract be terminated or not be renewed, the
Executive agrees that he will not within the geographical area



                                        5

of the United States, engage, either directly or indirectly, individually or as
an owner, partner, joint venturer, employee, officer, director, stockholder,
consultant, independent contractor or lender of or to any corporation, holding
Company or other business entity which is in a business similar to that of
Company or any of its affiliates. In the event that Company chooses to exercise
its option to prevent the Executive from competing with Company following
termination or non-renewal of his employment, Company shall notify the Executive
in writing within two (2) weeks following his last day of employment or within
two (2) weeks of notice by Company of its decision that the Executive shall take
a leave-of-absence, in either case specifying the period of up to one year
following termination, resignation, or non-renewal of employment during which
such competitive activity shall be prohibited. In the event Company exercises
its option, Company shall continue to pay Executive his Base Salary at the time
of termination, resignation or non-renewal for the period during which the
Executive is prohibited from competition with Company. Notwithstanding the
foregoing, the Executive (as hereinbefore described in Section 2(d)) may own
five (5%) percent of the securities of any business in competition with the
business of Company or any of its affiliates, which securities are regularly
traded on a public exchange, provided that any such ownership shall not result
in the Executive becoming a record or beneficial owner at any time of more than
five (5%) percent of equity securities of said business entity.

             (b) The Executive shall not during the term of his Employment under
this Agreement or any renewal thereof, and for a period of one (3) years

or retain any person who was employed by Company or any of its affiliated
companies having an annual compensation of at least U.S. $50,000 per annum
during the term of this Agreement or any renewal thereof.

             (c) If any provision of this Section is held to be unenforceable
because of the scope, duration or area of its applicability or otherwise, the
legal entity making that determination will have the power to modify the scope,
duration or area, or all of them, and the provision will then apply in its
modified form.

       9.    PROPERTY. All letters, memoranda, documents, business notes
(including all copies thereof) and other information contained on any other
computer media including computer disks and hard drives of the Executive in any
manner relating to the duties of Executive under this agreement are the property

                              EMPLOYMENT AGREEMENT


     THIS AGREEMENT made as of this 1st day of October, 1997, by and between
Jack Burt of 64 Cromwell Place, Old Saybrook, CT 06475 ("Executive") and
Biosystems, Inc., a corporation organized under the laws of Pennsylvania (the
"Company").

                              W I T N E S S E T H :

     Bacou USA, Inc. has entered into an agreement to purchase the company and
desires to clarify the terms and conditions which Executive shall continue to be
employed by the company; and

     WHEREAS, Company wishes to secure the services of Executive as President
and Chief Executive Officer for the period provided in this Agreement; and

     WHEREAS, Executive is willing to enter into this Agreement for such period
and on the terms and conditions hereinafter set forth;

     NOW, THEREFORE, in consideration of the mutual promises herein contained,
Company and Executive hereby agree as follows:

     1.    EMPLOYMENT. During the period of employment set forth in Section 2 of
this Agreement, Company shall employ Executive, and Executive shall serve as
President and Chief Executive Officer of Company. Executive agrees to faithfully
perform the duties assigned to him to the best of his ability and, except for
vacations and periods of temporary illness, to devote his full time and
attention to the business of Company. Ancillary employment such as writing,
teaching or lecturing, as well as the acceptance of honorific titles may be
undertaken by the Executive only with the written approval of the Chief
Executive Officer of Bacou USA, Inc. or the Executive Vice President in the
Chairman's absence. Executive also agrees that he will not engage in any other
business activities without the prior approval of the Chairman of the Company.
Executive may only serve as an officer, director, trustee or committee member,
or in any similar position, of a reasonable number (maximum two) of trade
associations and religious, charitable, educational, civic or other non-business
organizations, subject to the approval of the Chairman. The Executive represents
and warrants to Company that he is now under no contract or agreement nor will
he execute any contract or agreement that will in any manner interfere, conflict
with or prevent him from performing his duties under the terms and conditions of
this Agreement, recognizing that his performance hereunder will require the
devotion of his full time and attention during and beyond regular business hours
during the Term (as hereinafter defined), including extensive travel.

     2.    PERIOD OF EMPLOYMENT. This Agreement shall become effective upon the
closing of the transaction in which Bacou USA, Inc. become the direct or
indirect owner of the Company and its terms shall be retroactively applicable to
the first day of the Initial Term, as defined herein. The Executive's employment
under this Agreement shall initially cover the period October 1, 1997 to




<PAGE>   2

December 31, 2001 (the "Initial Term"). On December 31, 2001, and at the end of
each year thereafter, the period of employment shall be automatically extended,
without further action by either party, for successive one year periods (each a
"Renewal Term") unless at least six months prior to the end of any Term either
party shall have served written notice on the other of its election to allow
this Agreement to terminate at the end of such Term. The Initial Term and any
Renewal Terms are hereinafter sometimes collectively referred to as the "Term."

     If either party notifies the other party that it shall not extend the
period of employment, Company may, at its option, decide that the Executive
shall take a leave-of-absence for part or all of the remaining time of his
employment, continuing to receive all compensation as if actively working;
provided, however, that the Company may not exercise such option prior to
December 31, 2000.

     3.    TERMINATION. The period of employment shall be terminated upon the
first to occur of the following:

     (i)   The expiration of the period of employment pursuant to Section 2 of
           this Agreement.

     (ii)  The Executive's death.

     (iii) The Executive becoming permanently disabled. Permanent disability
           shall mean physical or mental incapacity which entitles Executive to
           receive benefits under the long-term disability plan provided for
           Executive pursuant to Section 4(e) of this Agreement.

     (iv)  The Executive's employment being terminated by Company for cause.
           Termination for cause shall mean termination by action of the Board
           of Directors of Company because of any of the following: (A) the
           willful failure of Executive, after written notice and reasonable
           opportunity to cure, to perform his duties and obligations under this
           Agreement or to execute in a reasonable and responsible manner the
           policies of Company; (B) after written notice and reasonable
           opportunity to cure, gross negligence in the performance of his
           duties under this Agreement; or (C) the commission by Executive of a
           felony.

     4.    COMPENSATION AND BENEFITS.

           (a) From October 1, 1997 to December 31, 1997, Executive shall
receive a total salary of Thirty-Two Thousand Five Hundred Dollars ($32,000.00)
which shall be paid in arrears, in periodic installments at the same times and
in the same manner as salaries paid to other employees of the Company, less the
usual payroll deductions. Beginning January 1, 1998, the Executive shall receive
regular compensation ("Base Salary") at the initial rate per annum of Two
Hundred Thirty Thousand Dollars ($230,000.00) per annum for the Initial Term.
The Base Salary shall be paid in arrears, in periodic installments at the same
times and in the same manner as salaries paid to other employees of the Company
less the usual payroll deductions. The Executive shall participate in any wage
increases applicable generally to salaried employees of Company.



                                      -2-

<PAGE>   3

The Base Salary prevailing at any time shall be reviewed annually for a possible
increase beginning in January 1999.

           (b) For the period from October 1, 1997 to December 31, 1997,

Executive shall be entitled to receive annual incentive compensation payments
("Incentive Compensation") at such times and in such amounts as may be
determined pursuant to the Bonus Plan for Executives of subsidiaries of Bacou
USA, Inc., as in effect for the applicable year; provided, however, that the
amount of Incentive Compensation for the fiscal year ending December 31, 2000
shall not exceed 35 percent of Executive's Base Salary for such year. Executive
acknowledges that, by agreeing to participate in the Bonus Plan for subsidiaries
of Bacou USA, Inc. he thereby waives any rights to participate in any other
incentive compensation plan of the Company.

           (c) Incentive Compensation shall be paid by Company for the prior
fiscal year within ten (10) days after a decision is made by the Board of
Directors of Company as to the amount of such Incentive Compensation, but in any
event no later than the earlier of the annual meeting of the Board of Directors
of Company or March 31.

           (d) The Executive shall be entitled to participate in any stock
option plan which Bacou USA, Inc. may adopt for Company at levels to be
determined by the Board of Directors of Company in their sole discretion.

thrift, retirement or pension, short term and long term disability, health and
accident, Blue Cross/Blue Shield, Major Medical or other hospitalization,
holiday, vacation, and other fringe benefit programs generally available to
Presidents of operating subsidiaries of Bacou USA, Inc. in accordance with and

matters of Company or its subsidiaries or affiliates, including, but not limited

with others, during or outside normal working hours, conceive, make, acquire or
suggest at any time which relate to the products, processes, work, research, or
other activities of Company or any of its subsidiaries or affiliates. Any and
all Inventions which are of a proprietary nature and which the Executive may
conceive, may acquire or suggest, either alone or in conjunction with others,
during his employment with Company (whether during or outside normal working
hours) relating to or in any way pertaining to or connected with Company's
business, shall be the sole and exclusive property of Company or its designee
and the Executive, whenever requested to do so by Company, shall, without
further compensation or consideration properly execute any and all applications,
assignments or other documents which Company or its designee shall deem
necessary in order to apply for and obtain Letters Patent of the United States
and/or comparable rights afforded by foreign countries for the Inventions, or in
order to assign and convey to Company or its designee the sole and exclusive
right, title and interest in and to the Inventions. This obligation shall
continue beyond the termination of this Agreement with respect to Inventions
conceived or made by the Executive during the term of his employment by Company,
and shall be binding upon his assigns, executors, administrators, and other
legal representatives.

     8.    NON-COMPETITION. (a) During the term of this Agreement or any renewal
thereof and, at Company's option for a period of up to one year thereafter,
should the Executive's contract be terminated or not be renewed, the Executive
agrees that he will not within the geographical area of the United States,
engage, either directly or indirectly, individually or as an owner, partner,
joint venturer, employee, officer, director, stockholder, consultant,
independent contractor or lender of or to any corporation, holding Company or
other business entity which is in a business similar to that of either the
Company or any respiratory protection business owned by Bacou USA, Inc. In the
event that Company chooses to exercise its option to prevent the Executive from
competing with Company following termination or non-renewal of his employment,
Company shall notify the Executive in writing within two (2) weeks following his
last day of employment or within two (2) weeks of notice by Company of its
decision that the Executive shall take a leave-of-absence, in either case
specifying the period of up to one year following termination, resignation, or
non-renewal of employment during which such competitive activity shall be
prohibited. In the event Company exercises its option, Company shall continue to
pay Executive his Base Salary at the time of termination, resignation or
non-renewal for the period during which the Executive is prohibited from
competition with Company. Notwithstanding the foregoing, the Executive may own
five (5%) percent of the securities of any business in competition with the
business of Company or any of its affiliates, which securities are regularly
traded on a public exchange, provided that any such ownership shall not result
in the Executive becoming a record or beneficial owner at any time of more than
five (5%) percent of equity securities of said business entity.

companies having an annual compensation of at least U.S. $50,000 per annum

duration or area, or all of them, and the provision will then apply in its
modified form.

                              EMPLOYMENT AGREEMENT

      THIS AGREEMENT made as of this 30th day of September, 1997 by and between
Joseph Burt ("Executive") and Biosystems, Inc., a corporation organized under
the laws of Pennsylvania (the "Company").

                              W I T N E S S E T H :

      WHEREAS, Bacou USA, Inc. has entered into an agreement to purchase the
Company and desires to clarify the terms and conditions upon which Executive
shall continue to be employed by the Company; and

      WHEREAS, Executive is now Vice President of Sales of the Company;

      WHEREAS, the Company wishes to secure the services of Executive as its
Vice President of Sales for the period provided in this Agreement; and

      WHEREAS, Executive is willing to enter into this Agreement for such period
and on the terms and conditions hereinafter set forth;

      NOW, THEREFORE, in consideration of the mutual promises herein contained,
the Company and Executive hereby agree as follows:

      1. EMPLOYMENT. During the period of employment set forth in Section 2 of
this Agreement, the Company shall employ Executive, and Executive shall serve as
Vice President of Sales of the Company. Executive agrees to faithfully perform
the duties assigned to him to the best of his ability and, except for vacations
and periods of temporary illness, to devote his full time and attention to the
Company's business. Ancillary employment such as writing, teaching or lecturing
as well as the acceptance of honorific titles may be undertaken by the Executive
only with the approval of the Chief Executive Officer of Bacou USA, Inc. or his
designee ("Chairman"). Executive also agrees that he will not engage in any
other business activities without the prior approval of the Chairman. Executive
may only serve as an officer, director, trustee or committee member, or in any
similar position, of a reasonable number (maximum two) of trade associations and
religious, charitable, educational, civic or other non-business organizations,
subject to the approval of the Chairman. The Executive represents and warrants
to Company that he is now under no contract or agreement nor will he execute any
contract or agreement that will in any manner interfere, conflict with or
prevent him from performing his duties under the terms and conditions of this
Agreement, recognizing that his performance hereunder will require the devotion
of his full time and attention during and beyond regular business hours during
the Term (as hereinafter defined), including substantial travel.

      2. PERIOD OF EMPLOYMENT. This Agreement shall become effective upon the
closing of the transaction in which Bacou USA, Inc. becomes the direct or
indirect owner of the Company and its terms shall be applicable to the first day
of the Initial Term, as defined herein. The Executive's employment under this
Agreement shall initially cover the period October 1, 1997 to 


<PAGE>   2


December 31, 2000 (the "Initial Term"). On January 1, 2001, and at the end of
each year thereafter, the period of employment shall be automatically extended,
without further action by either party, for successive one year periods (the
"Renewal Term") unless at least six months prior to the end of any Term either
party shall have served written notice on the other of its election to allow
this Agreement to terminate at the end of such Term. The Initial Term and any
Renewal Terms are hereinafter sometimes collectively referred to as the "Term."

      If either party notifies the other party that it shall not extend the
period of employment, Company may, at its option, decide that the Executive
shall take a leave-of-absence for part or all of the remaining time of his
employment, continuing to receive all compensation as if actively working.

      3.       TERMINATION. The period of employment shall be terminated upon 
the first to occur of the following:

      (i)      The expiration of the period of employment pursuant to Section 2
               of this Agreement.

      (ii)     The Executive's death.

      (iii)    The Executive becoming permanently disabled. Permanent disability
               shall mean physical or mental incapacity of a nature which
               prevents Executive from performing his duties under this
               Agreement for a period of more than six months in any twelve
               month period.

      (iv)     The Executive's employment being terminated by the Company for
               cause. Termination for cause shall mean termination by action of
               the Board of Directors of the Company because of the willful
               failure of Executive to perform his duties and obligations under
               this Agreement or failure to execute in a reasonable and
               responsible manner the policies of the Company or gross
               negligence in the performance of his duties under this Agreement
               or the commission by Executive of a felony.

      4.  COMPENSATION AND BENEFITS.

      (a) During the Employment Period, the Executive shall receive regular
compensation (the "Base Salary") at the initial rate of One Hundred and Sixty
Thousand Dollars ($160,000.00) per annum for the period January 1, 1997 through
December 31, 1998. The executive shall receive a salary of fifty thousand
dollars ($50,000.00) for the period October 1, 1997 through December 31, 1997
(the "Stub Period Salary"). The Base Salary and the Stub Period Salary shall be
payable in arrears less the usual payroll deductions at the same times and in
the same manner as salaries paid to other employees. The Executive shall
participate in any wage increases applicable generally to the Company's salaried
employees. The Base Salary prevailing at any time shall be reviewed annually for
a possible increase on January 1 of each year beginning in 1999.

applicable year; provided, however, that the percentage bonus for the Fiscal
Year ending December 31, 2000 shall not exceed thirty-five percent (35%) of
Executive's Base Salary for such year. Executive acknowledges that, by agreeing
to participate in the Bonus Plan for Executives of subsidiaries of Bacou USA,
Inc., he thereby waives any rights to participate in any other incentive

any Incentive Compensation for the period October 1, 1997 through December 31,
1997.

      (c) Incentive Compensation shall be paid by the Company for the prior

Directors of the Company or March 31.

option agreement attached hereto as Exhibit A, Executive shall be granted
options to purchase three thousand (3,000) shares of common stock of Bacou USA,
Inc. at a per share price equal to the closing price on September 30, 1997.

valid for the fiscal year in which vacation days are not taken.

               (iii) When traveling on Company business, the Executive will be

agrees that during and after the term of this Agreement he will not (except as
authorized by the Company or in the proper performance of his duties or except
as ordered by a court or other body of competent jurisdiction or as otherwise
required by law), directly or indirectly, divulge, disclose or appropriate to
his own use, or to the use of any third party, any secret, proprietary or

concerning such confidential matters of the Company or its subsidiaries or
affiliates, including, but not limited to, information pertaining to trade
secrets, systems, manuals, confidential reports, methods, processes, designs,
equipment lists, operating procedures, equipment and methods used and preferred
by the Company's customers. Upon termination of this Agreement, the Executive
shall promptly deliver to the Company all materials of a secret or confidential
nature relating to the business of the Company or any of its subsidiaries or
affiliates which are, directly or indirectly, in the possession or under the
control of the Executive. The provisions of this paragraph shall continue to
apply after the Executive ceases to be employed by the Company for a period of
three (3) years except in respect of any information or knowledge disclosed to
the public, other than through an unauthorized disclosure by the Executive.

      7. TRADE SECRETS. The Executive covenants that he shall, while employed by
the Company, assign, transfer, and set over to the Company or its designee all
right, title and interest in and to all trade secrets, secret processes,
inventions, improvements, patents, patent applications, trademarks, trademark
applications, copyrights, copyright registrations, discoveries and/or other
developments (hereinafter "Inventions") which he may, thereafter, alone or in
conjunction with others, during or outside normal working hours, conceive, make,
acquire or suggest at any time which relate to the products, processes, work,
research, or other activities of the Company or any of its subsidiaries or
affiliates. Any and all Inventions which are of a proprietary nature and which
the Executive may conceive, may acquire or suggest, either alone or in
conjunction with others, during his employment with the Company (whether during

connected with the Company's business, shall be the sole and exclusive property
of the Company or its designee and the Executive, whenever requested to do so by
the Company, shall, without further compensation or consideration

the Company or its designee shall deem necessary in order to apply for and
obtain Letters Patent of the United States and/or comparable rights afforded by
foreign countries for the Inventions, or in order to assign and convey to the
Company or its designee the sole and exclusive right, title and interest in and
to the Inventions. This obligation shall continue beyond the termination of this
Agreement with respect to Inventions conceived or made by the Executive during
the term of his employment by the Company, and shall be binding upon his
assigns, executors, administrators, and other legal representatives.

      8. NON-COMPETITION. (a) During the term of this Agreement or any renewal
thereof and, at the Company's option for a period of up to one year thereafter,
should the Executive's contract be terminated or not be renewed, the Executive
agrees that he will not within the geographical area of the United States,
engage, either directly or indirectly, individually or as an owner, partner,
joint venturer, employee, officer, director, stockholder, consultant,
independent contractor or lender of or to any corporation, holding company or
other business entity which is in a business similar to that of the Company or
any of its affiliates. In the event that the Company chooses to exercise its
option to prevent the Executive from competing with the Company following
termination or non-renewal of his employment, the Company shall notify the
Executive in writing within two (2) weeks following his last day of employment
or within two (2) weeks of notice by the Company of its decision that the
Executive shall take a leave-of-absence, in either case specifying the period of
up to one year following termination, resignation, or non-renewal of employment
during which such competitive activity shall be prohibited. In the event the
Company exercises its option, the Company shall continue to pay Executive his
Base Salary at the time of termination, resignation or non-renewal for the
period during which the Executive is prohibited from competition with the
Company. Notwithstanding the foregoing, the Executive (as hereinbefore described
in Section 2(d)) may own five (5%) percent of the securities of any business in
competition with the business of the Company or any of its affiliates, which
securities are regularly traded on a public exchange, provided that any such
ownership shall not result in the Executive becoming a record or beneficial
owner at any time of more than five (5%) percent of equity securities of said
business entity.

      (b) The Executive shall not during the term of his Employment under this
Agreement or any renewal thereof, and for a period of one (1) year thereafter,

having an annual compensation of at least U.S. $50,000 per annum during the term
of this Agreement or any renewal thereof.

      (c) If any provision of this Section is held to be unenforceable because
of the scope, duration or area of its applicability or otherwise, the legal
entity making that determination will have the power to modify the scope,
duration or area, or all of them, and the provision will then apply in its
modified form.

                              EMPLOYMENT AGREEMENT

      THIS AGREEMENT made as of this 30th day of September, 1997 by and between
Jeffrey M. Whynall ("Executive") and Biosystems, Inc., a corporation organized
under the laws of Pennsylvania (the "Company").

                              W I T N E S S E T H :

      WHEREAS, Bacou USA, Inc. has entered into an agreement to purchase the
Company and desires to clarify the terms and conditions upon which Executive
shall continue to be employed by the Company; and

      WHEREAS, Executive is now Director of Engineering of the Company;

      WHEREAS, the Company wishes to secure the services of Executive as its
Vice President of Engineering for the period provided in this Agreement; and

      WHEREAS, Executive is willing to enter into this Agreement for such period
and on the terms and conditions hereinafter set forth;

      NOW, THEREFORE, in consideration of the mutual promises herein contained,
the Company and Executive hereby agree as follows:

      1. EMPLOYMENT. During the period of employment set forth in Section 2 of
this Agreement, the Company shall employ Executive, and Executive shall serve as
Vice President of Engineering of the Company. Executive agrees to faithfully
perform the duties assigned to him to the best of his ability and, except for
vacations and periods of temporary illness, to devote his full time and
attention to the Company's business. Ancillary employment such as writing,
teaching or lecturing as well as the acceptance of honorific titles may be
undertaken by the Executive only with the approval of the Chief Executive
Officer of Bacou USA, Inc. or his designee ("Chairman"). Executive also agrees
that he will not engage in any other business activities without the prior
approval of the Chairman. Executive may only serve as an officer, director,
trustee or committee member, or in any similar position, of a reasonable number
(maximum two) of trade associations and religious, charitable, educational,
civic or other non-business organizations, subject to the approval of the
Chairman. The Executive represents and warrants to Company that he is now under
no contract or agreement nor will he execute any contract or agreement that will
in any manner interfere, conflict with or prevent him from performing his duties
under the terms and conditions of this Agreement, recognizing that his
performance hereunder will require the devotion of his full time and attention
during and beyond regular business hours during the Term (as hereinafter
defined), including limited travel.

      2. PERIOD OF EMPLOYMENT. This Agreement shall become effective upon the
closing of the transaction in which Bacou USA, Inc. becomes the direct or
indirect owner of the Company and its terms shall be applicable to the first day
of the Initial Term, as defined herein. The Executive's employment under this
Agreement shall initially cover the period October 1, 1997 to 



<PAGE>   2

December 31, 2000 ("the "Initial Term"). On January 1, 2001, and at the end of
each year thereafter, the period of employment shall be automatically extended,
without further action by either party, for successive one year periods (the
"Renewal Term") unless at least six months prior to the end of any Term either
party shall have served written notice on the other of its election to allow
this Agreement to terminate at the end of such Term. The Initial Term and any
Renewal Terms are here collectively referred to as the "Term."

      If either party notifies the other party that it shall not extend the
period of employment, Company may, at its option, decide that the Executive
shall take a leave-of-absence for part or all of the remaining time of his
employment, continuing to receive all compensation as if actively working.

      3. TERMINATION. The period of employment shall be terminated upon the
first to occur of the following:

      (i)      The expiration of the period of employment pursuant to Section 2
               of this Agreement.

      (ii)     The Executive's death.

      (iii)    The Executive becoming permanently disabled. Permanent disability
               shall mean physical or mental incapacity of a nature which
               prevents Executive from performing his duties under this
               Agreement for a period of more than six months in any twelve
               month period.

      (iv)     The Executive's employment being terminated by the Company for
               cause. Termination for cause shall mean termination by action of
               the Board of Directors of the Company because of the willful
               failure of Executive to perform his duties and obligations under
               this Agreement or failure to execute in a reasonable and
               responsible manner the policies of the Company or gross
               negligence in the performance of his duties under this Agreement
               or the commission by Executive of a felony.

      4.  COMPENSATION AND BENEFITS.

      (a) During the Employment Period, the Executive shall receive regular
compensation (the "Base Salary") at the initial rate of One Hundred and Twenty
Five Thousand Dollars ($125,000.00) per annum for the period October 1, 1997
through December 31, 1998. The Base Salary shall be payable in arrears less the
usual payroll deductions at the same times and in the same manner as salaries
paid to other employees. The Executive shall participate in any wage increases
applicable generally to the Company's salaried employees. The Base Salary
prevailing at any time shall be reviewed annually for a possible increase on
January 1 of each year beginning in 1999.

       (b) In addition to the Base Salary, the Executive shall be entitled to
receive annual

such amounts as may be determined pursuant to the Bonus Plan for Executives of
subsidiaries of Bacou USA, Inc., as in effect for the applicable year; provided,
however, that the percentage bonus for the Fiscal Year ending December 31, 2000
shall not exceed thirty-five percent (35%) of Executive's Base Salary for such
year. Executive acknowledges that, by agreeing to participate in the Bonus Plan
for Executives of subsidiaries of Bacou USA, Inc., he thereby waives any rights
to participate in any other incentive compensation plan of the Company. The
Executive will not be eligible to receive any Incentive Compensation for the
period September 30, 1997 through December 31, 1997.

      (c) Incentive Compensation shall be paid by the Company for the prior
fiscal year within ten (10) days after a decision is made by the Board of
Directors of the Company as to the amount of such Incentive Compensation, but in
any event no later than the earlier of the annual meeting of the Board of
Directors of the Company or March 31.

      (d) The Executive shall be entitled to participate in any stock option
plan which Bacou USA, Inc. may adopt for the Company at levels to be determined
by the board of directors of the Company in their sole discretion. In connection
with the execution of this Agreement and subject to the execution of the stock
option agreement attached hereto as Exhibit A, Executive shall be granted
options to purchase three thousand (3,000) shares of common stock of Bacou USA,
Inc. at a per share price equal to the closing price on September 30, 1997.

      (e) The Executive shall be entitled to participate in all savings, thrift,
retirement or pension, short term and long term disability, health and accident,
Blue Cross/Blue Shield, Major Medical or other hospitalization, holiday,
vacation, and other fringe benefit programs generally available to senior
executives of the Company in accordance with and subject to the terms and
conditions of such programs.

      (f) In addition, the Executive shall be entitled to receive the following
benefits:

the Automobile Policy of Bacou USA, Inc..

               (ii) The Executive shall be entitled to vacation pursuant to the
Company's Executive Vacation Policy. Vacation days will be taken at a time
convenient for both the Executive and the Company. To the extent the Executive
does not take all vacation days the remaining days will be carried forward for
an unlimited period or be paid to the Executive at the level of his Base Salary
valid for the fiscal year in which vacation days are not taken.

               (iii) When traveling on Company business, the Executive will be
provided coach-class airfare on domestic trips; business class airfare will be
provided on international trips with a duration of seven hours or greater if
requested by the Executive.

               (iv) The Executive is authorized to incur reasonable expenses in
connection with and for the promotion of the business of the Company, including

required by law), directly or indirectly, divulge, disclose or appropriate to
his own use, or to the use of any third party, any secret, proprietary or
confidential information or knowledge obtained by him during the term hereof
concerning such confidential matters of the Company or its subsidiaries or
affiliates, including, but not limited to, information pertaining to trade
secrets, systems, manuals, confidential reports, methods, processes, designs,
equipment lists, operating procedures, equipment and methods used and preferred
by the Company's customers. Upon termination of this Agreement, the Executive
shall promptly deliver to the Company all materials of a secret or confidential
nature relating to the business of the Company or any of its subsidiaries or
affiliates which are, directly or indirectly, in the possession or under the
control of the Executive. The provisions of this paragraph shall continue to
apply after the Executive ceases to be employed by the Company for a period of
three (3) years except in respect of any information or knowledge disclosed to
the public, other than through an unauthorized disclosure by the Executive.

      7. TRADE SECRETS. The Executive covenants that he shall, while employed by
the Company, assign, transfer, and set over to the Company or its designee all
right, title and interest in and to all trade secrets, secret processes,
inventions, improvements, patents, patent applications, trademarks, trademark
applications, copyrights, copyright registrations, discoveries and/or other
developments (hereinafter "Inventions") which he may, thereafter, alone or in
conjunction with others, during or outside normal working hours, conceive, make,
acquire or suggest at any time which relate to the products, processes, work,
research, or other activities of the Company or any of its subsidiaries or
affiliates. Any and all Inventions which are of a proprietary nature and which
the Executive may conceive, may acquire or suggest, either alone or in
conjunction with others, during his employment with the Company (whether during
or outside normal working hours) relating to or in any way pertaining to or
connected with the Company's business, shall be the sole and exclusive property
of the Company or its designee and the Executive, whenever requested to do so by
the Company, shall, without further compensation or consideration properly
execute any and all applications, assignments or other documents which the
Company or its designee shall deem necessary in order to apply for and obtain
Letters Patent of the United

States and/or comparable rights afforded by foreign countries for the
Inventions, or in order to assign and convey to the Company or its designee the
sole and exclusive right, title and interest in and to the Inventions. This
obligation shall continue beyond the termination of this Agreement with respect
to Inventions conceived or made by the Executive during the term of his
employment by the Company, and shall be binding upon his assigns, executors,
administrators, and other legal representatives.

      8. NON-COMPETITION. (a) During the term of this Agreement or any renewal
thereof and, at the Company's option for a period of up to one year thereafter,
should the Executive's contract be terminated or not be renewed, the Executive
agrees that he will not within the geographical area of the United States,
engage, either directly or indirectly, individually or as an owner, partner,
joint venturer, employee, officer, director, stockholder, consultant,
independent contractor or lender of or to any corporation, holding company or
other business entity which is in a business similar to that of the Company or
any of its affiliates. In the event that the Company chooses to exercise its
option to prevent the Executive from competing with the Company following
termination or non-renewal of his employment, the Company shall notify the
Executive in writing within two (2) weeks following his last day of employment
or within two (2) weeks of notice by the Company of its decision that the
Executive shall take a leave-of-absence, in either case specifying the period of
up to one year following termination, resignation, or non-renewal of employment
during which such competitive activity shall be prohibited. In the event the
Company exercises its option, the Company shall continue to pay Executive his
Base Salary at the time of termination, resignation or non-renewal for the
period during which the Executive is prohibited from competition with the
Company. Notwithstanding the foregoing, the Executive (as hereinbefore described
in Section 2(d)) may own five (5%) percent of the securities of any business in
competition with the business of the Company or any of its affiliates, which
securities are regularly traded on a public exchange, provided that any such
ownership shall not result in the Executive becoming a record or beneficial
owner at any time of more than five (5%) percent of equity securities of said
business entity.

      (b) The Executive shall not during the term of his Employment under this
Agreement or any renewal thereof, and for a period of one (1) year thereafter,
employ, retain or arrange to have any other person or entity employ or retain
any person who was employed by the Company or any of its affiliated companies
having an annual compensation of at least U.S. $50,000 per annum during the term
of this Agreement or any renewal thereof.

      (c) If any provision of this Section is held to be unenforceable because
of the scope, duration or area of its applicability or otherwise, the legal
entity making that determination will have the power to modify the scope,
duration or area, or all of them, and the provision will then apply in its
modified form.

      9. PROPERTY. All letters, memoranda, documents, business notes (including
all copies thereof) and other information contained on any other computer media
including computer disks and hard drives of the Executive in any manner relating
to the duties of Executive under this agreement are the property of the Company.

Re: First Amendment to Employment Agreement

Dear Walter:

Reference is made to that certain Employment Agreement between the Corporation
and you dated January 1, 1996 (the "Employment Agreement"). Once agreed and
accepted by you in the space provided below, Section 6(b) of the Employment
Agreement shall be amended to read as follows, effective for 1997 and future
years:

     "In addition to the Base Salary, the Employee shall be entitled to receive
an annual incentive compensation payment ("Incentive Compensation") in an amount
calculated as follows:

     2.75% of Adjusted EBIT up to $10,000,000
     3.25% of Adjusted EBIT over $10,000,000, up to $20,000,000
     3.75% of Adjusted EBIT over $20,000,000, up to $30,000,000
     4.25% of Adjusted EBIT over $30,000,000

     "For purposes of this Agreement, Adjusted EBIT shall mean Bacou's earnings
before interest and taxes, as reported in its consolidated financial statements
for the calendar year for which the computation is made, increased to eliminate
the effects of the following: (i) any accrual for the Employee's Incentive
Compensation; (ii) amortization expense; and (iii) any non-recurring charges
(including but not limited to the non-recurring effects of purchase accounting
treatment of acquisitions such as inventory step-ups and purchased research and
development).

     "Incentive Compensation shall be paid by Bacou for any year by the earlier
of ninety (90) days following the last day of such year or ten (10) days after
the amount of such Incentive Compensation has been calculated."

Re: Third Amendment to Employment Agreement

Dear Phil:


Reference is made to that certain Employment Agreement between the Corporation
and you dated May 8, 1995, as amended by that certain First Amendment dated
June 30, 1995, and that certain Second Amendment dated December 31, 1995 (as
so amended, the "Employment Agreement"). Once agreed and accepted by you in the
space provided below, the Employment Agreement shall be amended by (i)
increasing the amount of annual Base Salary payable pursuant to Section 5(b)
thereof to $250,000 effective January 1, 1998, and (ii) effective for 1997 and
future years, changing Section 5(c) of the Employment Agreement to read as
follows:

     "In addition to the Base Salary, the Employee shall be entitled to receive
an annual incentive compensation payment ("Incentive Compensation") in an
amount calculated as follows:

     0.40% of Adjusted EBIT up to $10,000,000
     0.45% of Adjusted EBIT over $10,000,000, up to $20,000,000
     0.50% of Adjusted EBIT over $20,000,000, up to $30,000,000
     0.55% of Adjusted EBIT over $30,000,000

     "For purposes of this Agreement, Adjusted EBIT shall mean Bacou's earnings
before interest and taxes, as reported in its consolidated financial statements
for the calendar year for which the computation is made, increased to eliminate
the effects of the following: (i) amortization expense; and (ii) any
