raw materials), in the ordinary course of Seller's business in accordance with
past practices. All items of inventory owned by Seller as of the date hereof, a
list of which is attached as part of Schedule 3.9, are accounted for in the
manner described in this Section 3.9 on the balance sheet included in the
September 30 Financial Statements.

            3.10 Material Contracts and Arrangements. Schedule 3.10 sets forth
all material contracts and arrangements to which Seller is a party to or bound
by in any manner. Each of such contracts and arrangements is valid, binding,
subsisting and enforceable in accordance with its terms and Seller has performed
all obligations required to be performed under any such contract or arrangement
and is not in breach or default or in arrears in any material respect or in any
other respect which would permit the other party to cancel such contract or
arrangement under the terms thereof.

            3.11 Ordinary Course of Business. Seller, from the date of the most
recent financial statements delivered to Buyer until the date hereof, has
operated its business in the normal, usual and customary manner in the ordinary
and regular course of business. Seller and each Stockholder have used his or its
best efforts to preserve intact Seller's business, properties, inventories,
operations, goodwill, and relations with employees, customers and others with
which Seller has business relationships (provided, that the foregoing shall not
be construed as a guarantee by Seller or any Stockholder that any customer,
supplier or employee will continue any contract or business relationship with
Buyer after Closing), and have maintained raw materials inventory, work in
process and finished goods at customary levels and in a manner strictly
consistent with Seller's past practice. From and after September 30, 2003,
neither Seller nor any Stockholder has, other than as set forth on Schedule
3.11, (i) disposed of any of its properties or assets valued at $5,000 or
greater except for inventory sold in the ordinary course of Seller's business
and cash expended in the ordinary course of Seller's business; (ii) purchased
assets valued at $5,000 or greater, except for inventory purchased in the
ordinary course of Seller's business; or (iii) made any distribution or dividend
to any of its stockholders. To the knowledge of Seller and each Stockholder
there is no dispute between Seller and any person relating to any obligation of
Seller that is not an Assumed Liability, or any basis for such a dispute.

            3.12 Litigation and Compliance with Laws. Except as set forth on
Schedule 3.12, neither Seller nor any Stockholder is engaged in, nor has Seller
or any Stockholder been threatened with, any litigation or legal or other
actions, suits, proceedings or investigations, at law or in equity or admiralty,
or before any federal, state, municipal or other governmental

<PAGE>

department, commission, board, agency or instrumentality, domestic or foreign,
in connection with the business or affairs or assets of Seller.

            3.13 Taxes. (a) Seller has filed all Tax Returns that it was
required to file. All such Tax Returns were correct and complete in all
respects. All Taxes owed by Seller (whether or not shown on any Tax Return) have
been paid. Seller is not the beneficiary of any extension of time within which
to file any Tax Return. No claim has ever been made by an authority in a
jurisdiction where Seller does not file Tax Returns that it is or may be subject
to taxation by that jurisdiction. There are no Security Interests on any of the
assets of Seller that arose in connection with any failure (or alleged failure)
to pay any Tax.

            (b) Seller has withheld and paid all Taxes required to have been
withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, stockholder, or other third party (except for
Taxes not yet due and payable).

            (c) No Stockholder or director or officer (or employee responsible
for Tax matters) of Seller expects any authority to assess any additional Taxes
for any period for which Tax Returns have been filed. There is no dispute or
claim concerning any Tax Liability of Seller, either (A) claimed or raised by
any authority in writing or (B) as to which any Stockholder, director or officer
(or employee responsible for Tax matters) of Seller has knowledge based upon
personal contact with any agent of such authority. Schedule 3.13 lists all
federal, state, local, and foreign income Tax Returns filed with respect to
Seller for taxable periods ended on or after December 31, 1999, indicates those
Tax Returns that have been audited, and indicates those Tax Returns that
currently are the subject of audit. Seller has delivered to Buyer correct and
complete copies of all federal income Tax Returns, examination reports, and
statements of deficiencies assessed against or agreed to by Seller since
December 31, 1999.

            (d) Seller has not waived any statute of limitations in respect of
Taxes or agreed to any extension of time with respect to a Tax assessment or
deficiency.

            (e) None of the Assumed Liabilities is an obligation to make a
payment that will not be deductible under Code ss.280G. Seller has disclosed on
its federal income Tax Returns all positions taken therein that could give rise
to a substantial understatement of federal income Tax within the meaning of Code
ss.6662. Seller is not a party to any Tax allocation or sharing agreement.
Seller (A) has not been a member of an Affiliated Group filing a consolidated
federal income Tax Return and (B) does not have any Liability for the Taxes of
any Person under Treas. Reg. ss.1.1502-6 (or any similar provision of state,
local, or foreign law), as a transferee or successor, by contract, or otherwise.

            (f) Seller has been a validly electing S corporation within the
meaning of Code ss.ss. 1361 and 1362 at all times during its existence, and
Seller will be an S corporation up to and including the Closing Date.

            (g) As used in this Agreement,

                        (i) "Security Interest" means any mortgage, pledge,
            lien, encumbrance, charge, or other security interest, other than
            (a) mechanic's, materialmen's, and similar liens, (b) liens for

<PAGE>

            Taxes not yet due and payable, (c) purchase money liens and liens
            securing rental payments under capital lease arrangements, and (d)
            other liens arising in the ordinary course of business and not
            incurred in connection with the borrowing of money.

                        (ii) "Tax" means any federal, state, local, or foreign

            capital stock, franchise, profits, withholding, social security (or
            similar), unemployment, disability, real property, personal
            property, sales, use, transfer, registration, value added,
            alternative or add-on minimum, estimated, or other tax of any kind
            whatsoever, including any interest, penalty, or addition thereto,
            whether disputed or not.

                        (iii) "Tax Return" means any return, declaration,
            report, claim for refund, or information return or statement
            relating to Taxes, including any schedule or attachment thereto, and
            including any amendment thereof.

and the operation of its facilities, and all such Environmental Permits are in
good standing and Seller is in compliance with all terms and conditions of such
Environmental Permits;

            (c) Neither Seller nor, to the best of Seller's knowledge, any of
its currently or previously owned or leased property or operations has been

                                   Article VI

                                 INDEMNIFICATION

            6.1 Indemnification By Seller and Stockholders. (a) Seller and each
Stockholder hereby jointly and severally agree at all times hereafter to
indemnify and hold harmless Buyer from and against any "Loss." For the purposes
of this Section 6.1, "Loss" shall mean:

<PAGE>

                      (i) any loss or liability resulting from any failure by
          Seller or Stockholder to perform, abide by or fulfill any of the
          agreements, covenants or obligations set forth in or entered into in
          connection with this Agreement to be so performed or fulfilled by
          Seller or Stockholder;

                      (ii) any loss or damages resulting from any breach or
          inaccuracy in any representation, warranty or agreement of Seller or
          Stockholder contained in this Agreement;

                      (iii) any loss or liability resulting from actions taken
          by Seller or Stockholder prior to the Closing Date to the extent such
          liability is not expressly assumed by Buyer pursuant to this
          Agreement; and

                      (iv) all actions, suits, judgments, damages, costs, and
          expenses, including reasonable attorneys' fees, incident to or arising
          out of any of the foregoing.

            (b) Notwithstanding any provision to the contrary, (i) no
Stockholder shall be liable under this Section 6.1 for any Loss caused solely by
any other Stockholder's willful misconduct, or by the breach of a representation
or warranty made solely by another Stockholder or covenant or other obligation
hereunder to be performed solely by another Stockholder, and (ii) neither Seller
nor any Stockholder shall be liable under this Section 6.1 for any such Loss
unless and until the aggregate amount of all Losses exceeds $10,000; provided,
that when the aggregate amount of all Losses exceeds $10,000, Seller and
Stockholders shall be liable for all such Losses.

            6.2 Indemnification By Buyer. (a) Buyer hereby agrees at all times
hereafter to indemnify and hold harmless Seller and Stockholders from and
against any "Loss." For the purposes of this Section 6.2, "Loss" shall mean:

                      (i) any loss or liability resulting from any failure by
          Buyer to perform, abide by or fulfill any of the agreements, covenants
          or obligations set forth in or entered into in connection with this
          Agreement to be so performed or fulfilled by Buyer;

                      (ii) any loss or damages resulting from any breach or
          inaccuracy in any representation, warranty or agreement of Buyer
          contained in this Agreement;

                      (iii) any loss or liability resulting from any claim
          arising out of any liability or obligation which is an Assumed
          Liability or resulting solely from any action taken by Buyer after the
          Closing; and

                      (iv) all actions, suits, judgments, damages, costs, and
          expenses, including reasonable attorneys' fees, incident to or arising
          out of any of the foregoing.

            6.3 Calculation of Loss. The amount of any Loss shall be the amount
of cash that, when received by the Claimant, shall place Claimant in the same
financial position it would have been in if such Loss had not occurred. For all
purposes of this Article 6, the amount of any Loss for breach of any
representation, warranty, covenant or agreement contained in this Agreement
shall be determined without giving effect to any qualification or limitation in
such representation, warranty, covenant or agreement as to materiality or
Material Adverse Effect, provided, that any

<PAGE>

such qualification or limitation shall be given effect in determining whether
there has been a breach of such representation, warranty, covenant or agreement.

            6.4 Indemnification Procedures. Seller or Buyer, as in the case may
be ("Claimant") shall give prompt written notice to Seller, a Stockholder or
Buyer as appropriate ("Indemnifying Party") of any claim (actual or threatened)
or other event which in the judgment of Claimant might result or has resulted in
a Loss by Claimant under Section 6.1 or 6.2. With respect to third-party claims,
the following provisions shall apply: Indemnifying Party shall have the right to
assume the defense of such claim or any litigation resulting therefrom,
provided, that (a) Indemnifying Party confirms in writing its obligation to
provide indemnification with respect to such claim, and (b) counsel for
Indemnifying Party, who shall conduct the defense of such claim (actual,
threatened or asserted) or litigation, shall be reasonably satisfactory to the
Claimant, and Claimant may participate in such defense at its expense, and
provided, further, that the omission by Claimant to give notice as provided
herein shall not relieve Indemnifying Party of its obligations hereunder except
to the extent that such omission results in a failure of actual notice to
Indemnifying Party and Indemnifying Party is damaged or prejudiced as a result
of such failure of actual notice. Indemnifying Party, in the defense of any such
claim or litigation, shall not, except with the consent of Claimant, consent to
the entry of any judgment or decree or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to the Claimant of a release from all liability in respect to such claim or
litigation (provided, that if Claimant does not so consent then any loss in
excess of the proposed settlement shall be paid by Claimant), and Indemnifying
Party shall have no liability with respect to any payment made by Claimant in
connection with the settlement, satisfaction or compromise of any claim unless
Indemnifying Party shall have approved thereof in advance in writing. If
Claimant shall not have received notice that Indemnifying Party shall assume the
defense of such claim within twenty (20) days after the notice is sent to
Indemnifying Party of the existence of such claim, then Claimant shall be free
to proceed with the defense of such claim at the expense of Indemnifying Party.
In such case, Indemnifying Party shall pay all expenses of defense promptly, and
in any event within five (5) days of submission of any invoice or bill for such
expenses to Indemnifying Party. Each such notice shall be accompanied (or
followed as promptly as is reasonably practicable after the amount of such Loss
becomes determinable) by a certificate signed by the President of Claimant, and
setting forth in reasonable detail the calculation of the amount of such Loss in
accordance with the provisions hereof, and accompanied by copies of all relevant
documents and records. The omission to give such notice or provide such
certificate by Claimant shall not relieve Indemnifying Party of its obligations
under this Article 6 except to the extent such omission results in a failure of
actual notice to Indemnifying Party and Indemnifying Party is damaged or
prejudiced by such failure of actual notice.

            6.5 Survival of Representations and Warranties. The several
representations, warranties and covenants of the parties herein contained,
including without limitation the provision of Section 7.9 below respecting
Confidential Information, shall survive the Closing Date and continue in effect
thereafter for a period equal to the applicable statute of limitations, except
that the provision of Section 7.9 shall only be subject to the sixty (60) month
period set forth in any Noncompetition and Confidentiality Agreement.

                                   Article VII

                                  MISCELLANEOUS

            7.1 Brokerage Fee. Seller and Buyer each represent that no broker
has been involved in this transaction and each party agrees to indemnify and
hold the other harmless from payment of any brokerage fee, finder's fee or
commission claimed by any party who claims to have been involved because of
association with such party.

            7.2 Amendments; Waivers. This Agreement constitutes the entire
agreement of the parties related to the subject matter of this Agreement,
supersedes all prior or contemporary agreements, representations, warranties,
covenants and understandings of the parties. This Agreement may not be amended,
nor shall any waiver, change, modification, consent or discharge be effected,
except by an instrument in writing executed by or on behalf of the party against
whom enforcement of any amendment, waiver, change modification, consent or
discharge is sought. In furtherance of the foregoing, the parties hereto
acknowledge that (i) there have been no representations, warranties, covenants,
understandings or agreements related to the subject matter of this Agreement
other than as set forth herein and therefore no reliance can be placed on
matters other than as set forth herein, and (ii) no agent of any party has or
had authority to make representations, warranties, covenants or agreements on
behalf of such party and if and to the extent so made, such representations,
warranties, covenants or agreements were not authorized and have not been the
subject upon which reliance has been placed.

            Any waiver of any term or condition of this Agreement, or of the
breach of any covenant, representation or warranty contained herein, in any one
instance, shall not operate as or be deemed to be or construed as a further or
continuing waiver of such term, condition or breach of covenant, representation
or warranty, nor shall any failure at any time or times to enforce or require
performance of any provision hereof operate as a waiver of or affect in any
manner such party's right at a later time to enforce or require performance of
such provision or of any other provision hereof; and no such written waiver,
unless it, by its own terms, explicitly provides to the contrary, shall be
construed to effect a continuing waiver of the provision being waived and no
such waiver in any instance shall constitute a waiver in any other instance or
for any other purpose or impair the right of the party against whom such waiver
is claimed in all other instances or for all other purposes to require full
compliance with such provision.

            7.3 Assignment; Successors and Assigns. This Agreement shall not be
assignable by any party without the written consent of the others, provided,
that Buyer may assign this Agreement and all of its rights hereunder to any
affiliated Person without such consent. This Agreement shall be binding upon and
shall inure to the benefit of the parties hereto and their respective successors
and permitted assigns.

            7.4 Severability. If any provision or provisions of this Agreement
shall be, or is found to be, invalid, inoperative or unenforceable as applied to
any particular case in any jurisdiction or jurisdictions, or in all
jurisdictions or in all cases, because of the conflict of any provision with any
constitution or statute or rule of public policy or for any other reason, such
circumstance shall not have the effect of rendering the provision or provisions
in question invalid, inoperative or unenforceable in any other jurisdiction or
in any other case or

<PAGE>

circumstance or of rendering any other provision or provisions herein contained
invalid, inoperative or unenforceable to the extent that such other provisions
are not themselves actually in conflict with such constitution, statute or rule
of public policy, but this Agreement shall be reformed and construed in any such
jurisdiction or case as if such invalid, inoperative or unenforceable provision
had never been contained herein and such provision reformed so that it would be

of Buyer, Seller or any Stockholder shall, directly or indirectly, make any

Information. "Confidential Information" means (i) the terms of this Agreement

            7.12 Governing Law; Consent to Jurisdiction.7.13 This Agreement will
be governed by and construed in accordance with the domestic laws of the State
of New Jersey, without giving effect to any choice of law or conflict provision
or rule (whether of the State of New Jersey or any other jurisdiction) that
would cause the laws of any jurisdiction other than the State of New Jersey to
be applied. In furtherance of the foregoing, the internal law of the State of
New Jersey will control the interpretation and construction of this Agreement,
even if under such jurisdiction's choice of law or conflict of law analysis, the
substantive law of some other jurisdiction would ordinarily apply. Buyer and
Seller hereby irrevocably submit to the jurisdiction of the courts of the State
of New Jersey and the Federal courts of the United States of America located in
the State of New Jersey solely in respect of the interpretation and enforcement
of the provisions of this Agreement and of the documents referred to in this
Agreement, and hereby waive any, and agree not to assert as a, defense in any
action, suit or proceeding for the interpretation or enforcement hereof or of
any such document, that it is not subject thereto or that such action, suit or
proceeding may not be brought or is not maintainable in said courts or that the
venue thereof may not be appropriate or that this Agreement or any of such
document may not be enforced in or by said courts, and the parties hereto
irrevocably agree that all claims with respect to such action or proceeding
shall be heard and determined in such a New Jersey State or Federal court. Buyer
and Seller hereby consent to and grant any such court jurisdiction over the
person of such parties and over the subject matter of any such dispute and agree
that mailing of process or other papers in connection with any such action or
proceeding in the manner provided in Section 7.7 hereof, or in such other manner
as may be permitted by law, shall be valid and sufficient service thereof.
