                                  ARTICLE III

                REPRESENTATIONS AND WARRANTIES OF THE CONTRIBUTOR

in the creation of any Encumbrance upon any of the assets of the Contributor,
any Contracts to which the Contributor is a party or by which the Contributor or

Person, or obtain any Permit, in each case, for the valid execution, delivery
and performance by the Contributor of this Agreement.

3.2  CERTAIN INVESTMENT REPRESENTATIONS.

     (a) The Contributor is an "accredited investor" as that term is defined in
Rule 501(a) of Regulation D under the Securities Act.

     (b) The Contributor is acquiring the Consideration Shares for investment
for the Contributor's own account and not with a view to, or for resale in
connection with, the distribution or other disposition thereof except in
compliance with the Stockholders Agreement and as permitted by law, including
without limitation the Securities Act. The Contributor does not have any present
intent to resell or distribute all or any part of its Consideration Shares. If
the Contributor is a corporation, trust, partnership or other organization, it
was not organized for the specific purpose of acquiring the Consideration
Shares.

     (c) The Contributor has been advised that the Consideration Shares have not
been registered under the Securities Act, that the Consideration Shares may not
be sold or otherwise disposed of unless they are registered thereunder or an
exemption from registration is available and that accordingly the Contributor
may be required to bear the economic risk of the investment in the Consideration
Shares for an indefinite period of time. The Contributor also understands that
the Corporation does not have any intention of registering the Consideration
Shares under the Securities Act or of supplying the information which may be
necessary to enable the Contributor to sell Consideration Shares pursuant to
Rule 144 under the Securities Act.

     (d) The Contributor has been given the opportunity to obtain any
information or documents, and to ask questions and receive answers about such
documents, the Corporation and its subsidiaries and the business and prospects
of the Corporation and its subsidiaries (including, without limitation, the
transactions to be consummated pursuant to the terms of the Merger Agreement) as
it deems necessary to evaluate the merits and risks related to its investment in
the Consideration Shares and no representations concerning such matters or any
other matters related to such investment have been made to the Contributor
except as set forth in this Agreement. The Contributor has had the opportunity
to consult its own attorney, accountant or investment advisor with respect to
the investment contemplated hereby and its suitability for the Contributor,
including the tax and other economic considerations related to the investment.

     (e) The Contributor (i) has knowledge and experience in financial and
business matters such that the Contributor is capable of evaluating the merits
and risks of the purchase of the Consideration Shares as contemplated by this
Agreement, (ii) understands and has taken cognizance of all risk factors related
to the purchase of the Consideration Shares and (iii) is able to bear the
economic risk of the investment in the Consideration Shares for an indefinite
period of time and can afford to suffer a complete loss of the investment in
such Consideration Shares.

     (f) The Contributor has been informed that the offer of the Consideration
Shares is being made pursuant to an exemption from the registration requirements
of the Securities Act relating to transactions by an issuer not involving a
public offering, and that, consequently, the


                                       -6-

<PAGE>

materials relating to the offer have not been subject to review and comment by
the staff of the Securities and Exchange Commission or any other Governmental
Authority.

     (g) The Contributor is not subscribing for the Consideration Shares as a
result of or subsequent to any advertisement, article, notice or other
communication published in any newspapers, magazine or similar media or
broadcast over television or radio, or presented at any seminar or meeting, or
any solicitation of a subscription by a person not previously known to the
Contributor in connection with investments in securities generally.

     (h) Each party hereby acknowledges, to the extent applicable, that
simultaneous with the consummation of the transactions contemplated by the
Merger Agreement, including without limitation the transactions contemplated by
this Agreement, the Contributor Loan Balance (as hereinafter defined) shall be
repaid in full by wire transfer of immediately available funds and/or by
directing Aearo to set off and net such Contributor Loan Balance against any
amounts the Contributor would otherwise be entitled to receive in connection
with the Merger to the Corporation, on behalf and in the name of the
Corporation. For purposes of this Section 3.2(h), the "Contributor Loan Balance"
shall mean the outstanding principal amount and interest owed by the Contributor
to the Corporation pursuant to a promissory note executed pursuant to an
Executive Security Purchase Agreement in connection with the purchase of the
Contributed Shares by the Contributor in the amount set forth on the signature
page hereto adjacent to the words "Contributor Loan Balance."

                                   ARTICLE IV

                       SECURITIES LAW COMPLIANCE; LEGENDS

4.1  STOCKHOLDERS' AGREEMENT; RESTRICTIVE LEGENDS.

     (a) The Contributor hereby acknowledges and agrees that the Consideration
Shares shall be subject to the Stockholders' Agreement, which is being executed
and delivered by the Contributor on the Contribution Closing Date.

     (b) The Consideration Shares shall be subject to the Stockholders'
Agreement, including, without limitation, the legending requirements set forth
therein and shall bear the following legends:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
     SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT
     WITH A VIEW TO DISTRIBUTION OR RESALE. THESE SECURITIES MAY NOT BE OFFERED
     FOR SALE, SOLD, DELIVERED AFTER SALE, TRANSFERRED, PLEDGED OR HYPOTHECATED
     IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT COVERING SUCH
     SECURITIES UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES
     LAWS, OR THE AVAILABILITY, IN THE OPINION


                                       -7-

<PAGE>

     OF COUNSEL, OF AN EXEMPTION FROM REGISTRATION THEREUNDER."

4.2  REMOVAL OF LEGENDS, ETC.

     Except as otherwise set forth in the Stockholders' Agreement, the legends
and restrictions imposed by Section 4.1 shall cease and terminate when (a) any
such Consideration Shares are sold or otherwise disposed of in accordance with
the intended method of disposition by the seller or sellers thereof set forth in
a registration statement or are sold or otherwise disposed of in a transaction
which does not require that the securities transferred bear the legends set
forth in Section 4.1, or (b) the holder of such Consideration Shares has met the
requirement for transfer of such Consideration Shares pursuant to the Securities
Act. Whenever the restrictions imposed by Section 4.1 shall terminate, as herein
provided, the holder of any Consideration Shares shall be entitled to receive
from the Corporation, without expense, a new certificate not bearing the
restrictive legend set forth in Section 4.1 and not containing any other
reference to the restrictions imposed by Section 4.1.

                                   ARTICLE V

                        NON-COMPETITION; NON-SOLICITATION

5.1  NON-COMPETITION.

     (a) As an inducement for the Corporation entering into the Merger
Agreement, as consideration for the right to make the investment contemplated by
this Agreement and for other good and valuable consideration, the sufficiency of
which is hereby acknowledged, the undersigned Contributor hereby covenants and
agrees that during the period commencing on the Contribution Closing Date and
ending on the third anniversary thereof (the "Non-Compete Termination Date," and
such period (as may be extended pursuant to Section 5.1(b)) below, the
"Non-Compete Period"), such Contributor will not, directly or indirectly, either
as principal, manager, agent, consultant, officer, stockholder, partner,
investor, lender or employee or in any other capacity, carry on, be engaged in
or have any financial interest in, any business which is in competition with the
business of the Corporation or any of its subsidiaries or any group, division or
Affiliate of the Corporation who is engaged in the same business or businesses
as the Corporation or any of its Affiliates (the "Restricted Group") at any time
during the Non-Compete Period. For purposes of this Section 5.1, a business will
be deemed to be in competition with the Restricted Group if, at any time during
the Non-Compete Period, it is involved in the sale, or other dealing in any
property or the rendering of any service sold, dealt in or rendered by the
Restricted Group as a part of the business of the Corporation or any of its
subsidiaries during the Non-Compete Period within the same geographic area in
which the Restricted Group effects such sales or dealings or renders such
services. Nothing in this Section 5.1 will be construed so as to preclude the
Contributor from (a) investing in any publicly-held company, provided his
beneficial ownership of any class of such company's securities does not exceed
5% of the outstanding securities of such class, (b) working in any sector of the
safety industry where neither the Corporation nor any subsidiary thereof is (i)
marketing or manufacturing products or (ii) to the knowledge of the Contributor,
acquiring, establishing or planning to acquire or establish a company that
markets or manufactures such products in that sector of the market or


                                       -8-

<PAGE>

(c) working for any employer if (i) such employer's aggregate revenues during
the then immediately preceding twelve (12) months derived from operations which
are in competition with the Restricted Group represent less than 10% of such
employer's gross revenues and the Contributor does not provide any services
directly or indirectly for such competing operations or (ii) the Restricted
Group has de minimis revenues resulting from businesses that are in competition
with such employer.

     (b) The Corporation may extend the Non-Compete Termination Date to the
fifth anniversary of the Contribution Closing Date in the event that the
Corporation repurchases all of the Consideration Shares from the Contributor
prior to the fifth anniversary of the Contribution Closing Date. Notwithstanding
the foregoing, the Corporation may only exercise its right to extend the
Non-Compete Period if it pays the cash purchase price for the Consideration
Shares within 60 days of (i) the repurchase of such shares by the Corporation or
(ii) the determination of the fair market value of such shares (as determined by
the Board in good faith).

5.2  NON-SOLICITATION.

     As an inducement for the Corporation entering into the Merger Agreement, as
consideration for the right to make the investment contemplated by this
Agreement and for other good and valuable consideration, the sufficiency of
which is hereby acknowledged, the undersigned Contributor hereby covenants and
agrees that during the period commencing on the Contribution Closing Date and
ending five (5) years from such date (the "Non-Solicit Termination Date"), such
Contributor will not, directly or indirectly, on his own behalf or on behalf of
any person, firm or company, hire any person who has been employed by any member
of the Restricted Group at any time during the twenty-four (24) month period
immediately preceding such hiring, or solicit or induce any such employee or any
customer of the Restricted Group to leave the employ of, or cease doing business
with, as applicable, the Restricted Group, or interfere, in any material way,
with the business of the Restricted Group. For purposes of clarification, this
Section 5.2 shall not apply to any action taken solely by any of the
Contributor's employers following the date of written notice of such
Contributor's termination of employment if (i) such Contributor did not provide
any assistance or recommendation for the benefit of such future employer
relating to the solicitation or hiring of any person referred to above and (ii)
such person referred to above does not become employed by the same division,
department or group within such future employer in which the Contributor is
employed and does not report to the Contributor.

5.3  REASONABLENESS.

     The Contributor hereby agrees that the covenants set forth in this Article
V are reasonable under the circumstances and will not interfere with his ability
to earn a living or to otherwise meet his financial obligations. The Contributor
further acknowledges that he has experience and expertise in industries and
businesses other than those that compete, either directly or indirectly, with
the Restricted Group and that the restrictions contained in this Article V will
not interfere with or otherwise impair the Contributor's ability to earn a
living or to otherwise meet his financial obligations in such other industries
or businesses. The Contributor believes that he has received sufficient
consideration and other benefits hereunder and in connection with the Merger to
clearly justify the restrictions contained in this Article V which, in any event
(given the


                                       -9-

<PAGE>

Contributor's education, skills and ability and his substantial experience in
industries other than that of the Restricted Group), the Contributor does not
believe would prevent him from otherwise earning a living. The Contributor has
carefully considered the nature and extent of the restrictions placed upon him
by this Agreement, and hereby acknowledges and agrees that the same are
reasonable in time and territory and do not confer a benefit upon the Company
disproportionate to the detriment of the Contributor. The Contributor and the
Corporation agree that if in the opinion of any court of competent jurisdiction
such restraint is not reasonable in any respect, such court will have the right,
power and authority to excise and modify such provision or provisions of this
covenant as so amended. The Contributor agrees that any breach of the covenants
contained in this Article V would irreparably injure the Corporation.
Accordingly, the Contributor agrees that the Corporation may, in addition to
pursuing any remedies it may have in law or in equity, cease making any payments
to the Contributor otherwise required by any contract between the Corporation
and the Contributor and obtain an injunction against the Contributor from any
court having competent jurisdiction over the matter restraining any further
violation of this Article V. The Contributor acknowledges and agrees that, in
the event of a termination of his employment with the Corporation or any of its
subsidiaries, this Article V will remain in force and effect and he will remain
bound by such provisions in accordance with their terms. The parties acknowledge
and agree that the covenants and agreements set forth in this Article V shall in
no way affect, restrict, impair or otherwise limit any other covenants or
agreements between the Contributor and the Corporation or any of its
subsidiaries that relate to the same or similar subject matter as this Article V
and have been entered into on or prior to the Contribution Closing Date.

                                   ARTICLE VI

                                  MISCELLANEOUS

6.1  DEFINITIONS.

     Capitalized terms used but not defined in this Agreement shall have the
respective meanings given to such terms in the Merger Agreement.

6.2  NO THIRD PARTY BENEFICIARIES.

     Except as expressly provided herein, this Agreement shall not confer any
rights or remedies upon any Person (as defined in the Stockholders Agreement)
other than the parties hereto and their respective successors and permitted
assigns, personal representatives and heirs and estates.

6.3  ENTIRE AGREEMENT.

     This Agreement constitutes the entire agreement among the parties hereto
and supersedes any prior understandings, agreements or representations by or
among the parties hereto, written or oral, with respect to the transactions
contemplated hereby.
