       2.3     PURCHASE PRICE ADJUSTMENT.

               (a)    Working Capital Statement. Within 90 days after the
       Closing Date, Buyer shall cause to be prepared and deliver to Riverside a
       working capital statement (the "WORKING CAPITAL STATEMENT") setting forth
       the Net Working Capital as of the Closing Date determined in accordance
       with GAAP and the Applicable Accounting Principles consistently applied,
       excluding the Company Debt, the Management Bonuses and the Selling
       Expenses (the "FINAL WORKING CAPITAL").

               (b)    Dispute. Within 30 days following receipt by Riverside of
       the Working Capital Statement, Riverside shall deliver written notice to
       Buyer of any dispute it has with respect to the preparation or content of
       the Working Capital Statement. If Riverside does not notify Buyer of a
       dispute with respect to the Working Capital Statement within such 30-day
       period, such Working Capital Statement will be final, conclusive and
       binding on the parties. In the event of such notification of a dispute,
       Buyer and Riverside shall negotiate in good faith to resolve such
       dispute. If Buyer and Riverside, notwithstanding such good faith effort,
       fail to resolve such dispute within 30 days after Riverside advises Buyer
       of its objections, then Buyer and Riverside jointly shall engage the firm
       of Ernst & Young LLP (the "ARBITRATION FIRM") to resolve such dispute. As
       promptly as practicable thereafter, Buyer and Riverside shall each
       prepare and submit a presentation to the Arbitration Firm. As soon as
       practicable thereafter, Buyer and Riverside shall cause the Arbitration
       Firm to chose one of the parties positions based solely upon the
       presentations by Buyer and Riverside. The party whose position is not
       accepted by the Arbitration Firm shall be responsible for all of the fees
       and expenses of the Arbitration Firm. All determinations made by the
       Arbitration Firm will be final, conclusive and binding on the parties.

               (c)    Access. For purposes of complying with the terms set forth
       in this SECTION 2.3, each party shall cooperate with and make available
       to the other parties and their respective representatives all
       information, records, data and working papers, and shall permit
       reasonable access to its facilities and personnel, as may be reasonably
       required in connection with the preparation and analysis of the Working
       Capital Statement and the resolution of any disputes thereunder.

               (d)    Downward Adjustment. If Final Working Capital (as finally
       determined pursuant to SECTION 2.3(b)) is less than the Target Working
       Capital, then the Purchase Price will be adjusted downward by the amount
       of such shortfall, and Riverside shall pay to Buyer, by bank wire
       transfer of immediately available funds to an account designated in
       writing by Buyer, an amount in cash equal to such shortfall. Such payment
       is to be made within five Business Days from the date on which Final
       Working Capital is finally determined pursuant to SECTION 2.3(b).

               (e)    Upward Adjustment. If Final Working Capital (as finally
       determined pursuant to SECTION 2.3(b)) is greater than the Target Working
       Capital, then the Purchase Price will be adjusted upward by the amount of
       such excess (the "UPWARD ADJUSTMENT Amount"), and Buyer shall pay or
       cause to be paid, by bank wire transfer of immediately available funds,
       to an account designated in writing by the Payment Agent an amount in
       cash equal to the Upward Adjustment Amount. The Upward Adjustment Amount
       shall


                                       11


       be made to the Payment Agent within five Business Days from the date on
       which the Final Working Capital is finally determined pursuant to SECTION
       2.3(b).

               (f)    Payment to the Stockholders and the Warrantholders of any
       Upward Adjustment Amount. As soon as practicable following the receipt by
       the Payment Agent of any Upward Adjustment Amount, the Upward Adjustment
       Amount will be distributed to the Stockholders and the Warrantholders as
       follows:

               (i)    Each Stockholder will be entitled to receive from the
               Payment Agent an amount in cash equal to the product of (A) the
               Upward Adjustment Share Amount and (B) the number of Shares
               previously owned by such holder immediately prior to the Closing.

               (ii)   Each Warrantholder will be entitled to receive from the
               Payment Agent an amount in cash equal to the product of (A) the
               Upward Adjustment Share Amount and (B) the number of shares of
               Common Stock for which the Warrants previously owned by such
               holder are exercisable immediately prior to the Closing.

       required to be reported to the appropriate state, local or foreign taxing
       authorities has been reported, and any additional Taxes due with respect
       thereto have been paid. The Company and each of its Subsidiaries has made
       all payments of estimated Taxes required to be made under Section 6655 of
       the Code and any analogous provisions of state, local or foreign Law.

       4.8     TITLE TO PROPERTIES. Except as set forth on SCHEDULE 4.8, the
Company or the Subsidiaries have good and valid title to all of the properties

       4.9     REAL PROPERTY. SCHEDULE 4.9 contains a complete and accurate
description in all material respects of all the Real Property and the Company's
interest therein. The Real Property listed on SCHEDULE 4.9 comprises all
material real property interests used in the conduct of the business and
operations of the Company as now conducted. All leased buildings and all leased
fixtures, equipment and other property and assets are held under leases or
subleases that are, in all material respects, valid instruments enforceable in
accordance with their respective terms, except as limited by (a) applicable
bankruptcy, reorganization, insolvency, moratorium or other similar Laws
affecting the enforcement of creditors' rights generally from time to time in
effect and (b) the availability of equitable remedies (regardless of whether
enforceability is considered in a proceeding at Law or in equity) (collectively,
the "GENERAL ENFORCEABILITY EXCEPTIONS"). The Company has delivered or made
available to Buyer true and complete copies of all material leases pertaining to
the Real Property. All Real Property (x) is available for immediate use in the
conduct of the business and operations of the Company, and (y) complies in all
material respects with all applicable building or zoning codes and regulations
of the Governmental Authority having jurisdiction.

       4.10    SUFFICIENCY OF PROPERTY. SCHEDULE 4.10 identifies as such and
contains a description, as of November 30, 2002, of all of the Company's and the
Subsidiaries' machinery, equipment and other tangible personal property that are
utilized in the operation of the Company's business (collectively, the "MATERIAL
EQUIPMENT"). The Material Equipment, together with the intangible assets of the
Company and the Subsidiaries, are sufficient for Buyer to continue the operation
of the Company's business, in all material respects, in accordance with
applicable Law as currently conducted by the Company. Except as set forth on
SCHEDULE 4.10, no Person, other than the Company or any Subsidiary, owns or
primarily utilizes any Material Equipment. The Material Equipment, when
considered in the aggregate, is structurally sound and in good operating
condition and repair, subject to normal wear and tear.

               (a)    is in material compliance with all Laws and Orders

       held by the Company or any Subsidiary.

of this Agreement, of all material Permits issued to the Company or any of its
Subsidiaries that are currently used by and are sufficient for operations of the
Company or any of its Subsidiaries in connection with their respective
businesses. Each of the Company and its Subsidiaries is in compliance in all
material respects with all such Permits, all of which Permits are in full force
and effect in all material respects and, to Sellers' Knowledge, there are no
pending or threatened terminations, expirations or revocations thereof.


                                       18


       4.13    EMPLOYEE BENEFIT PLANS.

               (a)    SCHEDULE 4.13(a) sets forth a complete list of (i) all
       "employee benefit plans," as defined in Section 3(3) of ERISA, (ii) all
       other severance pay, salary continuation, bonus, incentive, stock option,
       retirement, pension, profit sharing or deferred compensation plans,
       contracts, programs, funds or arrangements of any kind, and (iii) all
       other employee benefit plans, contracts, programs, funds, or arrangements
       in respect of any employees of the Company or any of the Subsidiaries or
       with respect to which the Company or any of the Subsidiaries has made or
       is required to make payments, transfers or contributions (all of the
       above being hereinafter individually or collectively referred to as
       "EMPLOYEE PLAN" or "EMPLOYEE PLANS," respectively).

               (b)    Copies of the following materials have been made available
       to Buyer: (i) all current plan documents for each Employee Plan, (ii) all
       determination letters from the Internal Revenue Service ("IRS") with
       respect to any of the Employee Plans, (iii) all current summary plan
       descriptions with respect to the Employee Plans, (iv) all current trust
       agreements and insurance contracts relating to the funding or payment of
       benefits under any Employee Plan, (v) the most recent annual report (Form
       5500 and all schedules thereto) filed with the IRS with respect to each
       Employee Plan, and (vi) the most recent actuarial valuation report for
       each Employee Plan as to which such a report is required.

               (c)    Each Employee Plan has been maintained, operated, and
       administered in compliance with its terms and any related documents or
       agreements and in compliance with all applicable Laws, in each case in
       all material respects.

               (d)    Each Employee Plan intended to be qualified under Section
       401(a) of the Code is so qualified and has heretofore been determined by
       the IRS to be so qualified, and each trust created thereunder has
       heretofore been determined by the IRS to be exempt from tax under the
       provisions of Section 501(a) of the Code, and nothing has occurred since
       the date of any such determination that could reasonably be expected to
       give the IRS grounds to revoke such determination.

               (e)    There are no Actions pending, or, to Sellers' Knowledge,
       threatened against any Employee Plan.

               (f)    All contributions required to be made to the Employee
       Plans have been made in accordance with the Employee Plans and, when
       applicable, Section 302 of ERISA and Section 412 of the Code. There has
       been no waiver, or application for a waiver, of the minimum funding
       standards imposed by Section 412 of the Code with respect to any Employee
       Plan, and no Employee Plan has an "accumulated funding deficiency" within
       the meaning of Section 412 of the Code as of the most recent plan year.

               (g)    No "prohibited transaction" (as defined in Section 4975 of
       the Code or Section 406 of ERISA) has occurred that involves the assets
       of any Employee Plan and that could subject the Company or any Subsidiary
       or any of their employees, or, to Sellers' Knowledge, a trustee,
       administrator or other fiduciary of any trusts created under


                                       19


       any Employee Plan to any material tax or material penalty on prohibited
       transactions imposed by Section 4975 of ERISA or the sanctions imposed
       under Title I of ERISA.

               (h)    No "pension plan" (as defined in Section 3(2) of ERISA)
       maintained or contributed to by the Company or a Subsidiary has been
       terminated, nor have there been any "reportable events" (as defined in
       Section 4043 of ERISA and the regulations thereunder) with respect
       thereto. Neither the Company, any Subsidiary nor any of their ERISA
       Affiliates (as defined below) have incurred any material unsatisfied
       liability under Title IV of ERISA. "ERISA AFFILIATE" means any "person"
       (as defined in Section 3(9) of ERISA) that is or has been a member of any
       group of persons described in Section 414 of the Code which includes the
       Company or any Subsidiary. As of the most recent valuation date for each
       Employee Plan that is a defined benefit pension plan, there was not any
       amount of "unfunded current liability" (as defined in Section
       412(l)(8)(A) of the Code) under such Employee Plan and, to the Sellers'
       Knowledge, there are no facts or circumstances that would materially
       change the funded status of any such Employee Plan.

               (i)    At no time within the preceding six years has the Company
       or any Subsidiary been required to contribute to any "multiemployer plan"
       (as defined in Section 4001(a)(3) of ERISA) or incurred any withdrawal
       liability, within the meaning of Section 4201 of ERISA, with respect to
       any such multiemployer plan.

               (j)    Each group health plan, as such term is defined in Section
       5000(b)(1) of the Code, that is sponsored or maintained by, or
       contributed to by, the Company or any Subsidiary complies in all material
       respects with the applicable requirements of Section 4980B of the Code.

               (k)    There is no Employee Plan under which as a result of the
       consummation of the transactions contemplated by this Agreement, either
       alone or in combination with another event, (A) any current or former
       employee may become entitled to severance pay or any other payment or (B)
       any compensation due any such employee from the Company or any Subsidiary
       may be increased or the time of payment or vesting may become
       accelerated. The consummation of the transactions contemplated by this
       Agreement will not result in, or satisfy a condition to the payment of
       compensation that would, in combination with any other payment, result
       in, an "excess parachute payment" within the meaning of Section 280G of
       the Code.

               (l)    Except as set forth on SCHEDULE 4.13(l), none of the
       Stockholders, the Company nor any Subsidiary have disseminated in writing
       or otherwise broadly or generally notified current or former employees of
       the Company or any Subsidiary of any intent or commitment (whether or not
       legally binding) to create or implement any additional plans, funds,
       programs, agreements or arrangements for the benefit of any current or
       former employees of the Company or any Subsidiary or to materially amend,
       modify or terminate any existing Employee Plan.

               (m)    Except for the Management Bonuses, no employee of the
       Company or any Subsidiary is entitled to any severance payment, any
       change of control payment or any other payment as a result of the
       transactions contemplated hereby.


                                       20

any of its Subsidiaries, or, to Sellers' Knowledge, any other party, in the
timely performance of any obligation to be performed or paid thereunder or any
other material provision thereof, in any such case that would have a Material

       4.24    ACCOUNTS RECEIVABLE. All accounts receivable of the Company or
any Subsidiary represent sales actually made in the ordinary course of business
or valid claims as to which full performance has been rendered by the Company or
any Subsidiary. The reserve on the Company Financial Statements against the
accounts receivable for returns and bad debts has been calculated in a manner
consistent with GAAP. All of the accounts receivable of the Company and the
Subsidiaries are, in the aggregate, collectible, net of the reserve therefor, in
the ordinary course of business. No counter claims, defenses or offsetting
claims with respect to the accounts receivable are pending or, to Sellers'
Knowledge, threatened, net of the reserve therefor. All of the accounts
receivable of the Company and the Subsidiaries relate solely to sales of goods
or services to customers of the Company or any Subsidiary, none of whom are
Affiliates of the Stockholders, the Company or any Subsidiary.

any Liens other than Permitted Liens.

bank account or safe deposit box.

       4.27    PRODUCTS. (a) Except as set forth on SCHEDULE 4.27, neither the
Company nor any Subsidiary has any material liability (and to Sellers' Knowledge
there is no reasonable basis for, and no Stockholder is aware of any present or
future Action against the Company or any Subsidiary giving rise to any
liability) arising out of any injury to any individuals or property as a result
of the ownership, possession, or use of any product manufactured, sold, leased
or delivered by the Company or any Subsidiary.


                                       25


               (b)    Each product the Company or any Subsidiary manufactured,
       sold, leased or delivered has been in conformity in all material respects
       with all applicable contractual commitments, regulatory requirements and
       all express and implied warranties, and none of the Company or the
       Subsidiaries have any material liability (and to Sellers' Knowledge,
       there is no reasonable basis for any present or future Action against any
       of them giving rise to any liability) for replacement or repair thereof
       or other damages in connection therewith. No product the Company or any
       Subsidiary manufactured, sold, leased or delivered is subject to any
       guaranty, warranty, or other indemnity beyond the applicable standard
       terms and conditions of sale and lease. SCHEDULE 4.27 sets forth copies

complete list of all the Indebtedness outstanding with respect to the Company or
any Subsidiary as of the date of this Agreement, including the amount (estimated

duly organized, validly existing and in good standing under the Laws of its
jurisdiction of incorporation or organization. Buyer is duly qualified to do
business, and in good standing, in each jurisdiction in which the character of
the properties owned or leased by it or in which the conduct of its business
requires it to be so qualified, except where the failure to be so qualified or
to be in good standing would not have a Material Adverse Effect on Buyer.

in the creation of a Lien (other than Permitted Liens) on any assets of Buyer
pursuant to, any of the terms, conditions or provisions of any note, bond,
mortgage, indenture, lease, license, contract, agreement or other instrument or
obligation to which Buyer is a party or by which Buyer or any of its properties
or assets may be bound, or (iv) violate any Order or Law applicable to Buyer or

       Company and the Subsidiaries and shall cause the Company and the
       Subsidiaries to permit Buyer to make such inspections as it may
       reasonably require and to furnish Buyer during such period with all such
       information relating to the Company and the Subsidiaries as Buyer may
       from time to time reasonably request. During such period, the Company and
       the Subsidiaries shall furnish Buyer such information and copies of such
       documents as Buyer may reasonably request.

               (b)    Any information provided to or obtained by Buyer pursuant
       to paragraph (a) above will be subject to the Confidentiality Agreement,
       dated November 15, 2002, between the Company and TriMas Corporation (the

       with and be subject to the terms of the Confidentiality Agreement.

               (c)    Buyer agrees to be bound by and comply with the provisions
       set forth in the Confidentiality Agreement as if such provisions were set
       forth herein, and such provisions are hereby incorporated herein by
       reference.

       7.3     HSR. The Company and Buyer shall, as promptly as practicable, but
in no event later than ten calendar days following the execution and delivery of
this Agreement, submit all filings required by the HSR Act (the "HSR FILING") to
the DOJ, as appropriate and thereafter provide any supplemental information
requested in connection therewith pursuant to the HSR Act and make any similar
filing within, to the extent reasonably practicable, a similar time frame with
any other Governmental Authority for which such filing is required. Any such
notification and report form and supplemental information will be in substantial
compliance with the requirements of the HSR Act or other applicable antitrust
regulation. The Company and Buyer shall furnish to the other such necessary
information and reasonable assistance as the other may request in connection
with its preparation of any filing or submission which is necessary under the
HSR Act or other applicable antitrust regulation. The Company and Buyer shall
request


                                       30



early termination of the applicable waiting period under the HSR Act and any
other applicable antitrust regulation. The Company and Buyer, will promptly
inform the other party of any material communication received by such party from
any Governmental Authority in respect of the HSR Filing. Each of the parties
will (a) use its respective commercially reasonable efforts to comply as
expeditiously as possible with all requests of any Governmental Authority for
additional information and documents, including, without limitation, information
or documents requested under the HSR Act or other applicable antitrust
regulation; (b) not (i) extend any waiting period under the HSR Act or any
applicable antitrust regulation or (ii) enter into any agreement with any
Governmental Authority not to consummate the transactions contemplated by this
Agreement, except, in each case, with the prior consent of the other parties;
and (c) cooperate with the other parties and use commercially reasonable efforts
to contest and resist any action, including legislative, administrative or
judicial action, and to have vacated, lifted, reversed or overturned any Order
(whether temporary, preliminary or permanent) that restricts, prevents or
prohibits the consummation of the transactions contemplated by this Agreement.
Without limiting the generality of the foregoing, Buyer agrees to propose,
negotiate and cooperate with the Company to effect prior to the Closing Date, by
consent decree, hold separate order or otherwise, the sale, divestiture or
disposition of such assets or businesses of itself, the Company or the
Subsidiaries (or otherwise take any action that limits the freedom of action
with respect to, or its ability to retain, any of its businesses, product lines,
or assets or those of the Company or the Subsidiaries) as may be required in
order to avoid the entry of, or to effect the dissolution of, any Order (whether
temporary, preliminary or permanent), which would otherwise have the effect of
preventing or delaying the consummation of the transactions contemplated hereby.
Buyer shall pay all filing fees under the HSR Act.

       7.4     PUBLICITY. Except as may be required to comply with the
requirements of any applicable Law or the rules and regulations of any stock
exchange or national market system upon which the securities of Buyer are
listed, no party will issue any press release or other public announcement
relating to the subject matter of this Agreement or the transactions
contemplated hereby without the prior approval (which approval will not be
unreasonably held or delayed) of the other party; provided, however, that, after
the Closing, the Stockholders will be entitled to issue any such press release
or make any such other public announcement without obtaining the prior approval
of Buyer, but shall nonetheless provide prior notice to Buyer.

       7.5     RECORDS. With respect to the financial books and records and
minute books of the Company relating to matters on or prior to the Closing Date:
(a) for a period of five years after the Closing Date, Buyer shall not cause or
permit their destruction or disposal without first offering to surrender them to
the Stockholders, and (b) where there is legitimate purpose, including, without
limitation, an audit of the Stockholders by the IRS or any other Taxing
Authority, Buyer shall allow the Stockholders and its representatives access to
such books and records during regular business hours.

       7.6     AMENDMENT TO DISCLOSURE SCHEDULES. Each of Buyer and the
Stockholders shall use commercially reasonable efforts to cause the conditions
set forth in SECTION 8.2 (in the case of Buyer) and SECTION 8.3 (in the case of
the Stockholders) to be satisfied by the Closing Date. From time to time prior
to the Closing Date, any of the parties hereto may deliver to the other a
written supplement or amendment to the sections of the disclosure schedules
relating to their respective representations and warranties in this Agreement
with respect to any matter, condition


                                       31


or occurrence hereafter arising which, if existing or occurring on the date
hereof, would have been required to be set forth or described in their
respective sections of the disclosure schedules. In the event that the Buyer, on
the one hand, or the other parties hereto, on the other hand, so supplement or
amend sections of the disclosure schedules, no such supplement or amendment will
be effective prior to the Closing, including for purposes of determining whether
the conditions to any party's obligations under ARTICLE VIII hereof have been
satisfied, but the disclosure schedules as so supplemented and amended shall, as
of the Closing Date and thereafter, be the disclosure schedules for determining
any inaccuracy in, or breach of, any representations and warranties of any
party; provided, however, that, with respect to any matter, condition or
occurrence arising from the conduct of business operations in the ordinary
course and consistent with past practice at any time after the date hereof (and
which does not have a Material Adverse Effect and which has not occurred as a
result of a breach of any covenant herein) and prior to the Closing Date, (a)
the specified representations and warranties made by the respective parties
hereto shall be deemed automatically modified to reflect such matter, condition
or occurrence as of the date that such event occurs or arises and (b) neither
party shall have the right to terminate this Agreement pursuant to SECTION 9.1
on account of such modification of the representations and warranties made by
the other party or parties hereto.

       best efforts to have any such Order overturned or lifted.

               (b)    All required HSR Filings shall have been made, and the

       representations or warranties were made on and as of the date of this
       Agreement and as of the Closing Date (except to the extent such
       representations and warranties speak as of a specific date or as of the
       date of this Agreement, in which case such representations and warranties
       shall be so true and correct or so true and correct in all material
       respects, as the case may be, as of such specific date or as of the date
       of this Agreement, respectively).

               (b)    Each of the agreements and covenants of the Stockholders
       to be performed and complied with by the Stockholders pursuant to this
       Agreement prior to or as of the Closing Date will have been duly
       performed and complied with in all material respects.

       delivered, to Buyer the items required by SECTION 3.2 of this Agreement.

                            TERMINATION OF AGREEMENT
                            ------------------------

       9.1     TERMINATION. Notwithstanding any other provision of this
Agreement, this Agreement may be terminated at any time prior to the Closing
Date:

               (a)    by mutual written consent of Buyer and Riverside (acting
       on its behalf and for the other Stockholders);

               (b)    by Buyer or Riverside (acting on its behalf and for the
       other Stockholders), upon written notice to the other party, if the
       transactions contemplated by this Agreement have not been consummated on
       or prior to July 27, 2003 (the "OUTSIDE DATE"), unless such failure of
       consummation shall be due to the failure of the party seeking such
       termination to perform or observe in all material respects the covenants
       and agreements hereof to be performed or observed by such party; or


                                       33


               (c)    by Buyer or Riverside (acting on its behalf and for the
       other Stockholders), upon written notice to the other party, if a
       Governmental Authority of competent jurisdiction has issued an Order or
       any other action permanently enjoining or otherwise prohibiting the
       consummation of the transactions contemplated by this Agreement, and such
       Order has become final and non-appealable; provided, however, that (i)
       the party seeking to terminate this Agreement pursuant to this clause (c)
       has used its reasonable best efforts to remove such Order;

               (d)    by Buyer, if there has been a material violation or breach
       by the Stockholders of any agreement, representation or warranty in this
       Agreement that has rendered the satisfaction of any condition to the
       obligations of Buyer impossible and such violation or breach has not been
       waived by Buyer; and

               (e)    by Riverside (acting on its behalf and for the other
       Stockholders), if there has been a material violation or breach by Buyer
       of any agreement, representation or warranty in this Agreement that has
       rendered the satisfaction of any condition to the obligations of the
       Stockholders impossible and such violation or breach has not been waived
       by the Stockholders.

       9.2     EFFECT OF TERMINATION. In the event of termination of this
Agreement pursuant to SECTION 9.1, notwithstanding any other provision of this
Agreement, no party will have any liability or any further obligation to any
other party, except as provided in this SECTION 9.2 and except that nothing
herein releases, or may be construed as releasing, any party hereto from any
liability or damage to any other party hereto arising out of the breaching
party's willful and material breach in the performance of any of its covenants,
agreements, duties or obligations arising under this Agreement. The obligations
of the parties to this Agreement under SECTIONS 7.2(b) and (c), 7.4 and 10.2
will survive any termination of this Agreement.

                            MISCELLANEOUS AND GENERAL
                            -------------------------

       10.1    SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS;
INDEMNIFICATION.

               (a)    Except with respect to SECTION 5.1 (Authority) and SECTION
       5.2 (Title), which shall survive the Closing indefinitely, none of the
       representations or warranties of the Stockholders contained in this
       Agreement will survive the Closing Date. From and after the Closing, the
       Stockholders shall, severally but not jointly, indemnify and hold
       harmless Buyer from, against and in respect of any and all liabilities,
       damages, losses, penalties, costs, claims, judgments, amounts paid in
       settlement, interest, penalties, assessments, out-of-pocket expenses
       (including reasonable attorneys' fees and disbursements) (collectively,
       "LOSSES") resulting from, incurred in connection with or arising out of
       (i) any breach of or inaccuracy in any representation or warranty of the
       Stockholders made in SECTIONS 5.1 and 5.2 of this Agreement; (ii) any
       Indebtedness of the Company or any Subsidiary existing immediately prior
       to the Closing that is not paid or otherwise retired at the Closing
       (excluding Items 5 (Insurance Premium Note) and 7 (Lease Guaranty) from
       SCHEDULE 4.28); (iii) any bonus or payment payable to any employee,
       consultant or Affiliate of the Company or any Subsidiary as a result of
       the transactions contemplated by this Agreement that is not paid or
       otherwise retired at the


                                       34


       Closing; and (iv) the fees and expenses of any outside professional
       services firm retained by the Company or any Subsidiary in connection
       with the transactions contemplated by this Agreement that are not paid or
       otherwise retired at the Closing.

               (b)    Except with respect to SECTION 6.3 (Authorization), which
       shall survive the Closing indefinitely, none of the representations or
       warranties of Buyer contained in this Agreement will survive the Closing
       Date. From and after the Closing, Buyer shall indemnify and hold harmless
       the Stockholders from, against and in respect of any and all Losses
       resulting from, incurred in connection with or arising out of any breach
       of or inaccuracy in any representation or warranty of Buyer made in
       SECTION 6.3 of this Agreement.

               (c)    All covenants and agreements contained herein providing
       for performance after the Closing Date will survive in accordance with
       their respective terms.

               (d)    If an indemnified party becomes aware of any matter that
       it believes is subject to indemnification under this Agreement, including
       receipt by any indemnified party of notice of the commencement of any
       action, proceeding, or other claim in respect of which the indemnified
       party intends to seek indemnification, the indemnified party shall
       promptly (and in any event no later than 30 days after it becomes aware)
       notify the indemnifying party in writing (a "CLAIM NOTICE"); provided,
       however, that failure to give such notice shall not relieve the
       indemnifying party of its obligations hereunder except to the extent that
       the indemnifying party is actually and materially prejudiced as a result
       of such failure. If the indemnifying party elects in writing within 15
       days of its receipt of a Claim Notice, the indemnifying party shall be
       entitled to assume control of the defense of such action or claim with
       counsel reasonably satisfactory to the indemnified party; provided,
       however, that:

              (i)     the indemnified party shall be entitled to participate in
              the defense of such claim and to employ counsel at its own expense
              (subject to SECTION 10.1(e)) to assist in the handling of such
              claim;

              (ii)    no indemnifying party shall consent to the entry of any
              judgment or enter into any settlement that does not include as an
              unconditional term thereof the giving by each claimant or
              plaintiff to each indemnified party of a release from all
              liability in respect of such claim or if, pursuant to or as a
              result of such consent or settlement, injunctive or other
              equitable relief would be imposed against the indemnified party or
              such judgment or settlement could materially interfere with the
              business, operations or assets of the indemnified party;

              (iii)   after written notice by the indemnifying party to the
              indemnified party of its election to assume control of the defense
              of any such action in accordance with the foregoing provisions,
              the indemnifying party shall not be liable to such indemnified
              party hereunder for any legal fees, costs and expenses
              subsequently incurred by such indemnified party in connection with
              the defense thereof, subject to SECTION 10.1(e) below.

                                       35


If the indemnifying party does not assume control of the defense of such claim
in accordance with the foregoing provisions, the indemnified party shall have
the right to defend such claim in such manner as it may deem appropriate,
including engaging counsel selected by the indemnified party and reasonably
satisfactory to the indemnifying party, at the reasonable cost and expense of
the indemnifying party, and the indemnifying party will promptly reimburse the
indemnified party therefore in accordance with this SECTION 10.1; provided,
however, that the indemnified party shall not be entitled to consent to the
entry of any judgment or enter into any settlement of such claim without the
prior written consent of the indemnifying party (which consent shall not be
unreasonably withheld or delayed).

               (e)    If both the indemnified party and the indemnifying party
       are parties to the action or claim for which indemnification is sought,
       and the indemnified party shall have been advised in writing by counsel
       reasonably acceptable to the indemnifying party that representation of
       both parties by the same counsel would, in the opinion of such counsel,
       be inappropriate due to actual or potential conflict of interests between
       such parties, the indemnified party may employ its own counsel and
       otherwise participate in the defense of such action or claim at the
       indemnifying party's expense.

               (f)    Notwithstanding the foregoing, each party has the right
       and in no event shall this Agreement limit the right of a party to pursue
       any remedy that may be available to such party under applicable Law in
       the event of fraud.

       10.2    EXPENSES. Whether or not the transactions contemplated by this
Agreement are consummated, all costs and expenses (including all legal,
accounting, broker, finder or investment banker fees) incurred in connection
with this Agreement and the transactions contemplated hereby are to be paid by
the party incurring such expenses except as expressly provided herein; provided,
however, that any costs and expenses incurred by the Company in connection with
the transactions contemplated hereby are to be paid by the Stockholders.

       10.3    SUCCESSORS AND ASSIGNS. This Agreement is binding upon and inures
to the benefit of the parties hereto and their respective successors and
assigns, but is not assignable by either party hereto without the prior written
consent of the other party hereto.

       10.4    THIRD PARTY BENEFICIARIES. Except with respect to the recipients
of the Management Bonuses in accordance with SECTION 2.2(e), each party hereto
intends that this Agreement does not benefit or create any right or cause of
action in or on behalf of any Person other than the parties hereto.

       10.5    FURTHER ASSURANCES. The parties shall execute such further
instruments and take such further actions as may reasonably be necessary to
carry out the intent of this Agreement. Each party hereto shall cooperate
affirmatively with the other parties, to the extent reasonably requested by such
other parties, to enforce rights and obligations herein provided.

       10.6    NOTICES. Any notice or other communication provided for herein or
given hereunder to a party hereto must be in writing, and sent by facsimile
transmission (electronically confirmed), delivered in person, mailed by first
class registered or certified mail, postage prepaid, or sent by Federal Express
