      corporations, group of trades or businesses under common control, or
      affiliated service group (as defined for purposes of Section 414(b), (c)

     or been a party to any nonexempt "prohibited transaction", as such term is
     defined in Section 4975 of the Code or Section 406 of ERISA, in connection
     with which, directly or indirectly, the Buyer or any of its affiliates,
     directors or employees or

<PAGE>

     any Employee Plan or any related funding medium could be subject to either
     a penalty assessed pursuant to Section 502(i) of ERISA or a tax imposed by
     Section 4975 of the Code.

          (c) COMPLIANCE. To the best knowledge of Sellers, with respect to all
     Company Employee Plans, the Company is in compliance with the terms of the

     all obligations required to be performed by it under, and is not in
     violation in any respect of, and there has been no default or violation by

     part within the meaning of ERISA or the Code; no liability has been
     incurred to, nor has any event or circumstance occurred, nor will any event
     or circumstance occur prior to the Closing Date, which could result in such
     a liability being asserted by, the Pension Benefit Guaranty Corporation
     with respect to any Company Employee Plan (other than the payment of annual
     premiums under Section 4007 of ERISA); nor has any Company Employee Plan
     that is subject to Part 3 of Subtitle B of Title I of ERISA or Section 412
     of the Code, or both, incurred any "accumulated funding deficiency" (as
     defined in ERISA), whether or not waived; nor has the Company failed to pay
     any amounts due and owing as required by the terms of any Company Employee
     Plan; nor has there been any "reportable event" within the meaning of
     Section 4043(b)(l)-(9) of ERISA, or any event described in Section 4063(a)
     of ERISA, with respect to any Company Employee Plan, other than as
     disclosed herein or on accompanying schedules.

          (d) MULTI EMPLOYER PLANS. Except as set forth on SCHEDULE 2.24,
     neither the Company nor any Member of the Controlled Group has ever been
     obligated to contribute to any "multi employer plan", as such term is

     the Controlled Group has any "withdrawal liability", as computed under
     Section 4211 of ERISA, with respect to any such plan and the Company and
     each Member of the Controlled Group has made all contributions to any such
     plan as are required through the Closing Date under the terms of any such
     plans or applicable statutes, regulations, rulings and other applicable
     law; and no event has occurred, or can occur prior to the Closing Date,
     which could give rise to any other liability (other than a continuing
     obligation to contribute to such plan(s) under the terms of any applicable
     collective bargaining agreements) on the part of the Company or any Member
     of the Controlled Group, the Buyer, or their affiliates, officers,
     employees or directors with respect to such plan(s).

     letters with respect to each such Company Employee Plan have been
     previously delivered by the Sellers or the Company to the Buyer, and
     nothing has since occurred, or will occur prior to the Closing Date, which

     requirements of the Code and ERISA, including, without limitation, all
     reporting and disclosure requirements.

          qualified profit-sharing or stock bonus plan, as defined in ERISA, all
          employer contributions accrued for plan years ending prior to the
          Closing Date under the Company Employee Plan terms and applicable law
          have been made by the Company.

               (iii) All premiums or other payments required by the terms of any

     affiliates be precluded or prevented from terminating or amending any
     Company Employee Plan.

     or appropriate in the reasonable opinion of the Buyer and the Buyer's
     counsel under all applicable laws and the terms of the Company Employee

<PAGE>

     9.1 BY THE SELLERS AND THE COMPANY. If the Closing occurs, the Sellers and
the Company hereby indemnify and hold harmless the Buyer, from and against all
claims, damages, losses, liabilities, costs and expenses (including, without
limitation, settlement costs and any legal, accounting or other expenses for
investigating or defending any actions or threatened actions) (collectively, the
"Losses") in connection with each and all of the following:

          (a) any material misrepresentation or breach of any representation or
     warranty made by the Sellers and the Company in this Agreement;

          (b) any material breach of any covenant, agreement or obligation of
     the Sellers and the Company contained in this Agreement or any other
     agreement, instrument or document contemplated by this Agreement;

          (c) any misrepresentation contained in any statement, certificate or
     schedule furnished by the Sellers and the Company pursuant to this
     Agreement or in connection with the transactions contemplated by this
     Agreement; and

          (d) any claim relating to the Company's business or operation prior to
     the Closing Date, other than any warranty or other claim relating to a
     product manufactured or sold by the Company prior to the Closing Date.

     9.2 BY THE BUYER. If the Closing occurs, the Buyer hereby indemnifies and
holds harmless the Sellers and the Company, from and against all claims,
damages, losses, liabilities, costs and expenses (including, without limitation,
settlement costs and any legal, accounting or other expenses for investigating
or defending any actions or threatened actions) (collectively, the "Losses") in
connection with each and all of the following:

          (a) any misrepresentation or breach of any representation or warranty
     made by the Buyer in this Agreement;

          (b) any breach of any covenant, agreement or obligation of the Sellers
     contained in this Agreement or any other agreement, instrument or document
     contemplated by this Agreement;

          (c) any misrepresentation contained in any statement, certificate or
     schedule furnished by the Buyer pursuant to this Agreement or in connection
     with the transactions contemplated by this Agreement; and

          (d) any claim relating to (i) products manufactured or sold by the
     Company after the Closing Date or (ii) the Company's business or operation
     after the Closing Date.

     9.3 CLAIMS FOR INDEMNIFICATION. Whenever any claim shall arise for
indemnification under this Section 9, the Buyer, the Sellers or the Company, as
the case may be, seeking indemnification (the "Indemnified Party"), shall
promptly notify the other party (the "Indemnifying Party") the claim and, when
known, the facts constituting the basis for such claim. In the event of any such
claim for indemnification hereunder resulting from or in connection with any
claim or legal proceedings by a third party, the notice shall specify, if known,
the amount or an estimate of the amount of the liability arising therefrom. The

                                       32
<PAGE>

Indemnified Party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent, which shall not be unreasonably withheld or delayed, of the
Indemnifying Party; provided, however, that if suit shall have been instituted
against the Indemnified Party and the Indemnifying Party shall not have taken
control of such suit after notification thereof as provided in Section 9.3 of
this Agreement, the Indemnified Party shall have the right to settle or
compromise such claim upon giving notice to the Indemnification Party as
provided in Section 9.3.

     9.4 DEFENSE BY THE INDEMNIFYING PARTY. In connection with any claim which
may give rise to indemnity hereunder resulting from or arising out of any claim
or legal proceeding by a person other than the Indemnifying Party, at the sole
cost and expense of the Indemnifying Party, may, upon written notice to the
Indemnified Party, assume the defense of any such claim or legal proceeding if
the Indemnifying Party acknowledges to the Indemnified Party in writing the
obligation of the Indemnifying Party to indemnify the Indemnified Party with
respect to all elements of such claim. If the Indemnifying Party assume the
defense of any such claim or legal proceeding, the Indemnifying Party shall
select counsel reasonably acceptable to the Indemnified Party to conduct the
defense of such claims or legal proceedings and at the sole cost and expense of
the Indemnifying Party shall take all steps necessary in the defense or
settlement thereof. The Indemnified Party shall thereafter be entitled to
participate in and assume control of the defense of any such action if the
Indemnified Party has a reasonable basis for concluding that its interests would
be better served. The Indemnifying Party shall not consent to a settlement of,
or the entry of any judgment arising from, any such claim or legal proceeding,
without the prior written consent of the Indemnified Party (which consent shall
not be unreasonably withheld or delayed). The Indemnified Party shall be
entitled to participate in (but not control) the defense of any such action,
with its own counsel and at its own expense. If the Indemnifying Party do not
assume the defense of any such claim or litigation resulting therefrom within 30
days after the date such claim is made: (a) the Indemnified Party may defend
against such claim or litigation in such manner as it may deem appropriate,
including, but not limited to, settling such claim or litigation, after giving
notice of the same to the Indemnifying Party, on such terms as the Indemnified
Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to
participate in (but not control) the defense of such action, with its counsel
and at its own expense. If the Indemnifying Party or the Indemnifying Party
thereafter seeks to question the manner in which the Indemnified Party defended
such third party claim or the amount or nature of any such settlement, the
Indemnifying Party shall have the burden to prove by a preponderance of the
evidence that the Indemnified Party did not defend or settle such third party
claim in a reasonably prudent manner.

     9.5 PAYMENT OF INDEMNIFICATION OBLIGATION. All indemnification by the
Buyer, Sellers or the Company hereunder, as the case may be (to the extent not
satisfied in the manner specified in the preceding sentence), and any
indemnification by the Sellers, Buyer or the Company, as the case may be, if the
Closing does not occur, shall be effected by payment of cash or delivery of a
cashier's or certified check in the amount of the indemnification liability.
Buyer shall, in addition to other remedies then available to it, have the right
to offset the amount of such indemnification claim against payments due from
Buyer to Seller. Buyer shall only be entitled to receive payment for Losses for
which it is otherwise entitled to be compensated under this Section 9 to the
extent such Losses in the aggregate exceed $25,000 (the "Basket Amount"). If
such Losses in the aggregate exceed the Basket Amount, Buyer shall be entitled
to payment of all losses pursuant to this Section 9 that are in excess of the
Basket Amount.

     9.6 SURVIVAL OF REPRESENTATIONS. All representations and warranties made by
the Sellers and the Company in this Agreement, or in any instrument or document
furnished in connection with this Agreement or the transactions contemplated
hereby, excluding those listed below, shall survive the Closing and any
investigation at any time made by or on behalf of the Indemnified Party for a
period of eighteen months. The representations and warranties provided in

or on behalf of the Indemnified Party for a period of three (3) years. The
representations and warranties provided in Section 2.22 shall survive the
Closing and any investigation at any time made by or on behalf of the
Indemnified Party for a period of five (5) years.

further obligation or liability to the Buyer under this Agreement.

     10.3 TERMINATION BY REASON OF BREACH. This Agreement may be terminated by

of the Sellers, the Company or the failure of the Sellers, or the Company to
perform any condition or obligation hereunder.

     10.4 AVAILABILITY OF REMEDIES AT LAW. In the event this Agreement is
