                           (iv) the Employment Agreements, executed by Company;

                           (v) the Escrow Agreement, executed by Buyer; and

                  (c) All of the transactions to be concluded at the Closing of
this Agreement shall be deemed concluded simultaneously. Unless waived, no
transaction or delivery shall be deemed finally concluded unless and until all
such transactions are concluded.

                  (d) Each Seller agrees that Sellers shall be solely
responsible for distributing among themselves the amounts delivered jointly to
Sellers by wire transfer to the account specified in Section 2.4(b)(i), and that
amounts so delivered shall be deemed appropriately distributed to each Seller in
accordance with this Agreement and the Noncompetition Agreement. Sellers have
directed that certain payments be delivered to the account of Lauren J.
Fleischmann a/k/a John Fleischmann as nominee and agent for all Sellers, and
each Seller agrees to look solely to John Fleischmann with regard to amounts
delivered to such account and to bear any and all risk of loss associated with
the use of such account. Buyer's delivery of funds via wire transfer in the
amounts and to the accounts specified in Section 2.4(b) shall, to the extent of
the funds so delivered and subject to the terms of the Escrow Agreement, fully
and finally discharge the obligation of Buyer with regard to the payment to
Sellers of the Purchase Price and the additional consideration specified in the
Noncompetition Agreements.

         2.5 ADJUSTMENT AMOUNT

         The Adjustment Amount (which may be a positive or negative number) will
be equal to (a) the Net Book Value as of the Effective Date determined in
accordance with Section 2.6 and GAAP, minus (b) Net Book Value as shown on the
February 28, 2001 Balance Sheet.

         2.6 ADJUSTMENT PROCEDURE

                  (a) Sellers will prepare or cause to be prepared consolidated
financial statements ("Closing Financial Statements") of the Company as of the
Effective Date in accordance with GAAP for the period from the date of the
Balance Sheet through the close of business on the day before the Effective
Date, including a computation of Net Book Value as of the Effective Date. The
fees and expenses of Sellers (including the fees and expenses of Sellers'
counsel, accountants, brokers, representatives and other agents), to the extent
paid or to be paid by Company as permitted hereunder, shall be reflected either
as a reduction in cash or as a liability in the Closing Financial Statements,
and no fees or expenses of Sellers shall be paid by the Company after the
Closing that are not reflected as liabilities on the Closing Financial
Statements. Sellers will deliver the Closing Financial Statements to Buyer
within 30 days after the Effective Date. If within 30 days following Buyer's
receipt of the Closing Financial Statements, Buyer has not given Sellers'
Representative notice of its objection to the Closing Financial Statements (such
notice must contain a statement of the basis of Buyer's objection),


                                       11
<PAGE>

then the Net Book Value reflected in the Closing Financial Statements will be
used in computing the Adjustment Amount. If Buyer gives such notice of objection
and Buyer and the Seller's Representative cannot agree with regard to such
objection within 14 days thereafter, then the issues in dispute will be
submitted to nationally recognized certified public accountants mutually agreed
upon by the parties (which have not been engaged by either party or their
Subsidiaries for at least two years prior to the date of delivery to Buyer of
the Closing Financial Statements) (the "Accountants"), for resolution. If issues
in dispute are submitted to the Accountants for resolution, (i) within fifteen
(15) business days after request, each party will furnish to the Accountants
such work papers and other documents and information relating to the disputed
issues as the Accountants may request and are available to that party or its
Subsidiaries (or its independent public accountants), and will be afforded the
opportunity to present to and discuss with the Accountants any material relating
to the dispute prior to the Accountants' determination; (ii) the determination
by the Accountants, as set forth in a notice delivered to Buyer and the Seller's
Representative by the Accountants, will be binding and conclusive on Buyer and
all Sellers in the absence of manifest error; and (iii) Buyer and Sellers will
each bear 50% of the fees of the Accountants for such determination unless all
issues are resolved against either Buyer or Sellers, in which event the
Accountants may, in their discretion, award arbitration expenses, including the
Accountants' fees, and counsel fees to the prevailing party.

                  (b) By the tenth business day following the final
determination of the Adjustment Amount, if the Purchase Price (after
consideration of the Adjustment Amount) is greater than the payment made
pursuant to Section 2.4(b)(i) and 2.4(b)(ii), Buyer will pay the difference to
Sellers, and if the Purchase Price (after consideration of the Adjustment
Amount) is less than such amount, Sellers will pay the difference to Buyer. All
payments will be made together with interest at the publicly announced prime
rate charged by Fleet Bank beginning on the Effective Date and ending on the
date of payment. Payments must be made in immediately available funds. The
Purchase Price shall be the Purchase Price as adjusted by the Adjustment Amount.
Payments to Sellers must be made in the manner set forth in Section 2.4(b)(i).
Payments to Buyer must be made by wire transfer to such bank account as Buyer
will specify. Any good faith dispute in the calculation of the Adjustment Amount
will not constitute a breach of any of the representations or warranties of
either Buyer or Sellers hereunder and will not give either party any right to
indemnification hereunder.

         3. REPRESENTATIONS AND WARRANTIES OF ORIGINAL SHAREHOLDERS.

         Original Shareholders jointly and severally represent and warrant to
Buyer as follows:

         3.1 ORGANIZATION AND GOOD STANDING. The Company is a corporation duly
organized, validly existing, and in good standing under the laws of the State of
Maryland, with full corporate power and authority to conduct its business as it
is now being conducted, to own or use the properties and assets that it purports
to own or use, and to perform all its obligations under Company Contracts. The
Company is duly qualified to do business as a foreign corporation and is in good
standing under the laws of Virginia, California, and Florida. With the exception
of the State of Rhode Island, there is no other state or other jurisdiction in
which either


                                       12
<PAGE>

the ownership or use of the properties owned or used by the Company, or the
nature of the activities conducted by it, requires such qualification, except
for those jurisdictions in which the failure to qualify will not have a Material
Adverse Effect.

         3.2 NO CONFLICT. Except as set forth in Part 3.2 of the Disclosure
Letter, neither the execution and delivery of this Agreement nor the
consummation or performance of any of the transactions contemplated hereby will,
directly or indirectly (with or without notice or lapse of time):

                  (a) contravene, conflict with, or result in a violation of (A)
any provision of the Organizational Documents of the Company, or (B) any
resolution adopted by the Board of Directors or the stockholders of the Company;

                  (b) contravene, conflict with, or result in a violation of, or
give any Governmental Body or other Person the right to challenge any of the
transactions contemplated hereby or to exercise any remedy or obtain any relief
under, any Legal Requirement or any Order to which the Company, or any of the
assets owned or used by the Company, or, to the Knowledge of the Company or
Original Shareholders, any Seller, may be subject;

                  (c) contravene, conflict with, or result in a violation of any
of the terms or requirements of, or give any Governmental Body the right to
revoke, withdraw, suspend, cancel, terminate, or modify, any Governmental
Authorization that is held by the Company or that otherwise relates to the
business of, or any of the assets owned or used by, the Company;

                  (d) cause the Company to become subject to, or to become
liable for the payment of, any Tax;

                  (e) to the Knowledge of the Company or Original Shareholders,
cause any of the assets owned by the Company to be reassessed or revalued by any
taxing authority or other Governmental Body;

                  (f) contravene, conflict with, or result in a violation or
breach of any provision of, or give any Person the right to declare a default or
exercise any remedy under, or to accelerate the maturity or performance of, or
to cancel, terminate, or modify, any Company Contract; or

                  (g) result in the imposition or creation of any Encumbrance
upon or with respect to any of the assets owned or used by the Company.

Neither the Sellers nor the Company is or will be required to give any notice to
or obtain any Consent from any Person in connection with the execution and
delivery of this Agreement or the consummation or performance of any of the
transactions contemplated hereby.

         3.3 CAPITALIZATION. The authorized equity securities of the Company
consist of 410,000 shares of Class A voting common stock, par value $.00108, and
41,000 shares of


                                       13
<PAGE>

Class B non-voting stock, par value $.00108, of which a total of 43,426 shares
of said Class A and 2,547 shares of Class B are issued and outstanding and
constitute the Shares. Sellers are the record and beneficial owners and holders
of the Shares, free and clear of all Encumbrances, the Shares constitute all of
the issued and outstanding equity securities of the Company and each Seller is
the sole record and beneficial owner of the Shares set forth after his name on
Part 3.3 to the Disclosure Letter as evidenced by the share certificates
identified by number as set forth in said Part 3.3. No legend or other reference
to any purported Encumbrance appears upon any certificate representing equity
securities of the Company other than an investment legend pursuant to the
Securities Act. All of the outstanding equity securities of the Company have
been duly authorized and validly issued and are fully paid and nonassessable.
There are no options, warrants, Convertible Securities or other Contracts upon
the exercise or conversion of which or pursuant to the terms of which any equity
securities or other securities of the Company may be issued or transferred by
the Company or any Seller. None of the outstanding equity securities or other
securities of the Company was issued in violation of the Securities Act or any
other Legal Requirement. The Company neither owns, nor has any Contract to
acquire, any equity securities or other securities of any Person (other than the
Company) or any direct or indirect equity or ownership interest in any other
business.

         3.4 FINANCIAL STATEMENTS. Sellers have delivered to Buyer: (a) audited
consolidated balance sheets of the Company as at February 28 in each of the
years 1999 and 2000, and the related audited statements of income, changes in
stockholders' equity, and cash flows for each of the fiscal years then ended,
together with the related notes and the unqualified report thereon of
Buchbinder, Tunick & Company, L.L.P., independent certified public accountants;
(b) an audited consolidated balance sheet of the Company as at February 28, 2001
(including the notes thereto, the "Balance Sheet"), and the related consolidated
statements of income, changes in stockholders' equity, and cash flows for the
fiscal year then ended, together with the related notes and the unqualified
report thereon of Buchbinder, Tunick & Company, L.L.P., independent certified
public accountants, and (c) an unaudited balance sheet of the Company as at July
31, 2001, and the related unaudited consolidated statements of income, changes
in stockholders' equity, and cash flow for the five (5) months then ended,
including in each case the notes thereto. Such financial statements fairly
present and reflect the consolidated financial condition and the results of
operations, changes in stockholders' equity, and cash flows of the Company as at
the respective balance sheet dates and for the periods then ended, all in
accordance with GAAP. The audited and unaudited financial statements described
in this Section 3.4 are collectively referred to as the Financial Statements.
The unaudited financial statements reflect all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the Company's
financial condition at July 31 and the results of its operations for the five
(5) months then ended. No financial statements of any Person other than the
Company are required by GAAP to be included in the consolidated financial
statements of the Company.

         3.5 BOOKS AND RECORDS. The books of account, minute books, stock record
books, and other records of the Company, all of which have been made available
to Buyer, are complete and correct and have been maintained in accordance with
sound business practices except that minute books of the Company do not contain
any minutes of meetings prior to 1989. The minute books of the Company contain
accurate and complete records of all meetings held of,


                                       14
<PAGE>

and corporate action taken by, the stockholders, the Boards of Directors, and
committees of the Boards of Directors of the Company, including any actions
taken by written consent in lieu of a meeting since 1989 and, except for minutes
preceding 1989, no meeting of any such stockholders, Board of Directors, or
committee has been held for which minutes have not been prepared and are not
contained in such minute books. All of those books and records are now in the
possession of the Company. Sellers have delivered to Buyer copies of the
Organizational Documents of the Company as currently in effect. Records of
meetings held of, and corporate action taken by, the stockholders, the Board of
Directors, and committees of the Board of Directors of the Company preceding
1989 have been inadvertently lost and are no longer in the possession of, or
available to, the Company or Original Shareholders. Nothing that would have been
reflected in such records, if available, materially and adversely affects the
assets, business, prospects, financial condition or results of operation of the
Company as of the Effective Date.

         3.6 TITLE TO PROPERTIES; ENCUMBRANCES.

                  (a) The Company owns all of the properties and assets (whether
real, personal, or mixed and whether tangible or intangible) as reflected as
owned in the books and records of the Company (including all of the properties
and assets reflected in the Financial Statements and all of the properties and
assets purchased or otherwise acquired by the Company since the date of the
Balance Sheet) except for (i) assets held under leases disclosed in Part 3.6 of
the Disclosure Letter, which information identifies those leases which are
operating leases and capital leases, and (ii) inventory and obsolete equipment
sold since the date of the Balance Sheet in the Ordinary Course of Business and
consistent with past practice. All such material properties and assets are free
and clear of all Encumbrances except mortgages or security interests disclosed
in the Financial Statements as securing specified liabilities or obligations
with respect to which no default (or event that, with notice or lapse of time,
or both, would constitute a default) exists, and liens for current taxes not yet
due.

                  (b) Part 3.6 of the Disclosure Letter sets forth a complete
and correct description of all material property (personal, real or mixed)
leased by the Company and a list of the leases covering such property. With
respect to each real property lease so listed, Part 3.6 of the Disclosure Letter
sets forth (i) the location of the premises covered by the lease; (ii) the date
of and parties to each lease amendment or modification; (iii) the current lease
termination date; (iv) the annual fixed rental for the current lease year; and
(v) the number and period of any renewal options. The Company has a valid
leasehold interest in all property so listed, binding on Company and, to the
Knowledge of Company or Original Shareholders, on the Lessor of such property,
free and clear of all Encumbrances. The Company enjoys peaceful and undisturbed
possession under all of the leases covering such property, and all such leases
are valid and subsisting, with no default thereunder. The Company owns good and
marketable title to, or has a valid leasehold interest in, all of the real
property used by the Company in its business as now conducted.

         3.8 ACCOUNTS RECEIVABLE. All accounts receivable of the Company that
are reflected on the Financial Statements, on Part 3.8 of the Disclosure Letter,
or on the accounting records of the Company as of the Effective Date
(collectively, the "Accounts Receivable") represent valid obligations arising
from sales actually made or services actually performed in the Ordinary Course
of Business. The Accounts Receivable are current and collectible net of the
respective reserves shown on the Financial Statements. Subject to such reserves,
each of the Accounts Receivable either has been or will be collected in full,
without any set-off, within one hundred eighty (180) days after the day on which
it first becomes due and payable. There is no contest, claim, or right of
set-off, other than returns in the Ordinary Course of Business which are
reflected in the reserves, under any Contract with any obligor of an Accounts
Receivable relating to the amount or validity of such Accounts Receivable. Part
3.8 of the Disclosure Letter contains a complete and accurate list of all
Accounts Receivable as of a date not earlier than ten (10) days prior to the
Effective Date, which list sets forth the aging of such Accounts Receivable.

         3.9 INTENTIONALLY OMITTED

         3.10 NO UNDISCLOSED LIABILITIES. Except as set forth in the Financial
Statements and Part 3.10 of the Disclosure Letter, the Company has no
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent, or otherwise) except for liabilities or
obligations reflected or reserved against in the Balance Sheet and current
liabilities incurred in the Ordinary Course of Business since the date thereof.

         3.11 TAXES.

                  (a) The Company has filed or caused to be filed (on a timely
basis since 1995) all Tax Returns that are or were required to be filed by or
with respect to it, either separately or as a member of a group of corporations,
pursuant to applicable Legal Requirements. Sellers have delivered to Buyer
copies of, and Part 3.11 of the Disclosure Letter contains a complete and
accurate list of, all such Tax Returns relating to income or franchise taxes
filed since 1995. The Company has paid all Taxes that have become due pursuant
to those Tax Returns or otherwise, or pursuant to any assessment received by

the Disclosure Letter and are being contested in good faith and as to which
adequate reserves (determined in accordance with GAAP) have been provided in the
Financial Statements.

                  (b) Part 3.11 of the Disclosure Letter contains a complete and
accurate list of all audits of all Tax Returns of the Company, including a
reasonably detailed description of the nature and outcome of each audit and a
schedule of all pending audits. All deficiencies proposed as a result of such
audits have been paid, reserved against, settled, or, as described in Part 3.11
of the Disclosure Letter, are being contested in good faith by appropriate
proceedings. Part 3.11 of the Disclosure Letter describes all adjustments to the
United States federal income Tax Returns filed by the Company or any group of
corporations including the Company for all taxable years since 1995, and the
resulting deficiencies proposed by the IRS. Except as described in Part 3.11


                                       16
<PAGE>

of the Disclosure Letter, none of Sellers nor the Company has given or been
requested to give waivers or extensions (or is or would be subject to a waiver
or extension given by any other Person) of any statute of limitations relating
to the payment of Taxes of the Company or for which the Company may be liable.

                  (c) The charges, accruals, and reserves with respect to Taxes
on the books of the Company are adequate (determined in accordance with GAAP)
and are at least equal to the Company's liability for Taxes. To the Knowledge of
Company or Original Shareholders, there exists no proposed tax assessment
against the Company except as disclosed in the Financial Statements or in Part
3.11 of the Disclosure Letter. No consent to the application of Section
341(f)(2) of the IRC has been filed with respect to any property or assets held,
acquired, or to be acquired by the Company. All Taxes that the Company is or was
required by Legal Requirements to withhold or collect have been duly withheld or
collected and, to the extent required, have been paid to the proper Governmental
Body or other Person.

                  (d) All Tax Returns filed by (or that include on a
consolidated basis) the Company are true, correct, and complete. Except as set
forth in Part 3.11 of the Disclosure Letter, there is no tax sharing agreement
that will require any payment by the Company after the date of this Agreement.
The Company is not, and within the five-year period preceding the Effective Date
has not been, an "S" corporation.

         3.12 NO MATERIAL ADVERSE CHANGE. Since the date of the Balance Sheet,
there has not been any Material Adverse Change affecting the Company, and no
event has occurred or circumstance exists that may result in such a Material
Adverse Change.

time Buyer may request, all documents, memoranda, notes, plans, records,
reports, and other documentation, models, components, devices, or computer
software, whether embodied in a disk or in other form (and all copies of all of
the foregoing), relating to the businesses, operations, or affairs of the
Company and any other Confidential Information that Seller may then possess or
have under Seller's control. If Seller breaches the covenants set forth in this
Section 5.4, each of Buyer and the Company, in addition to the right to recover
Damages as provided in Section 6 and any other rights it may have, shall have
the right to obtain injunctive or other equitable relief to restrain any breach
or threatened breach or otherwise to specifically enforce the provisions of this
Section 5.4,


                                       36

it being agreed that money damages alone would be inadequate to compensate the
Buyer and the Company and would be an inadequate remedy for such breach.

         6. INDEMNIFICATION; REMEDIES.

         6.1 SURVIVAL; RIGHT TO INDEMNIFICATION NOT AFFECTED BY KNOWLEDGE.
Subject to Section 6.5, below, all representations, warranties, covenants, and
obligations in this Agreement, and any other certificate or document delivered
pursuant to this Agreement, will survive the Closing. The right to
indemnification, payment of Damages or other remedy based on such
representations, warranties, covenants, and obligations will not be affected by
any investigation conducted with respect to, or any Knowledge acquired (or
capable of being acquired) at any time, whether before or after the Effective
Date, with respect to the accuracy or inaccuracy of or compliance with, any such
representation, warranty, covenant, or obligation. The waiver of any condition
based on the accuracy of any representation or warranty will not affect the
right to indemnification, payment of Damages, or other remedy based on such
representations and warranties. Any payment made by an Original Shareholder to
Buyer pursuant to this Section 6 shall be deemed to be a reduction in the
Purchase Price and shall not be deemed to be an item of income or expense, and
all parties hereto agree to prepare their tax returns consistent therewith.

         6.2 INDEMNIFICATION AND PAYMENT OF DAMAGES BY ORIGINAL SHAREHOLDERS.
Original Shareholders, jointly and severally, will indemnify and hold harmless
Buyer and the Company and their respective successors and assigns (collectively,
the "Indemnified Persons") for, and will pay to the Indemnified Persons the
amount of, any loss, liability, claim, damage (including incidental and
consequential damages), expense (including costs of investigation and defense
and reasonable attorneys' fees) or diminution of value, whether or not involving
a third-party claim (collectively, "Damages"), arising, directly or indirectly,
from or in connection with:

                  (a) any Breach of any representation or warranty made by
Original Shareholders in Section 3 of this Agreement;

                  (b) any product shipped or manufactured by, or any services
provided by, the Company prior to the Effective Date;

                  (c) any claim by any Person for brokerage or finder's fees or
commissions or similar payments based on any agreement or understanding alleged
to have been made by any such Person with any Seller (or any Person acting on
any Seller's behalf) in connection with the transactions contemplated hereby;

                  (d) any Breach of any representation or warranty made by any
Seller in this Agreement or any certificate or document delivered by any Seller
pursuant to this Agreement, other than those contained in Section 3 or those
referred to in Section 6.2(c);

                  (e) any Breach by any Seller of any covenant or obligation of
such Seller in


                                       37
<PAGE>

this Agreement or any other agreement or document delivered by such Seller
pursuant to this Agreement;

                  (f) any claim or right of any Former Shareholder against the
Company or Buyer or any of its securities or otherwise arising in connection
with or related to the transactions or matters described in, or contemplated by,
this Agreement or the Former Shareholder Releases;

                  (g) any claim by, or related to, Janice or Janet Buxbaum;

                  (h) any claim related to or arising in connection with the
proceeding styled Cynthia A. Metzler, Acting Secretary of Labor v. David Bennet,
et. al., Case No. L 97-1022 in the United States District Court for the District
of Maryland, or the facts alleged therein or giving rise thereto, excluding,
however, any claim caused by the failure of the Company timely to make the two
remaining $75,000 payments specified in the Consent Judgment filed April 7,
1997;

                  (i) the failure of Company to qualify to do business in Rhode
Island before the Effective Date; or

                  (j) any claim that, at the time of the consummation of the
transactions contemplated by this Agreement, any Person other than Sellers owns
or holds, or has any right, title or interest in or to, any equity securities of
the Company.

The remedies provided in this Section 6.2 will not be exclusive of or limit any
other remedies that may be available to Buyer or the other Indemnified Persons.

         6.3 INDEMNIFICATION AND PAYMENT OF DAMAGES BY ORIGINAL SHAREHOLDERS;
ENVIRONMENTAL MATTERS. Consistent with the provisions of Section 6.2, Original
Shareholders, jointly and severally, will indemnify and hold harmless Buyer and
the other Indemnified Persons for, and will pay to Buyer, the Company, and the
other Indemnified Persons the amount of, any Damages (including costs of
cleanup, containment, or other remediation) arising, directly or indirectly,
from or in connection with:

                  (a) any Environmental, Health, and Safety Liabilities arising
out of or relating to: (i) (A) the ownership, operation, or condition at any
time on or prior to the Effective Date of the Facilities or any other properties

Effective Date, or (B) any Hazardous Activities that were, or were allegedly,
conducted by Sellers or the Company or by any other Person for whose conduct
they are or may be held responsible; or


                                       38

                  (b) any bodily injury (including illness, disability, and
death, and regardless of when any such bodily injury occurred, was incurred, or
manifested itself), personal injury, property damage (including trespass,
nuisance, wrongful eviction, and deprivation of the use of real property), or
other damage of or to any Person, including any employee or former employee of
Sellers or the Company or any other Person for whose conduct they are or may be

the Effective Date on or at the Facilities (or present or suspected to be
present on any other property, if such Hazardous Material emanated or allegedly
emanated from any of the Facilities and was present or suspected to be present
on any of the Facilities on or prior to the Effective Date) or (ii) Released or
allegedly Released by Sellers or the Company or any other Person for whose
conduct they are or may be held responsible, at any time on or prior to the

Buyer will be entitled to control any Cleanup, any related Proceeding, and,
except as provided in the following sentence, any other Proceeding with respect
to which indemnity may be sought under this Section 6.3. The procedure described
in Section 6.8 will apply to any claim solely for monetary damages relating to a
matter covered by this Section 6.3.

         6.4 INDEMNIFICATION AND PAYMENT OF DAMAGES BY BUYER. Buyer will

Breach of any representation or warranty made by Buyer in this Agreement or in
any certificate delivered by Buyer pursuant to this Agreement, (b) any Breach by
Buyer of any covenant or obligation of Buyer in this Agreement, (c) any claim by
any Person for brokerage or finder's fees or commissions or similar payments
based upon any agreement or understanding alleged to have been made by such
Person with Buyer (or any Person acting on its behalf) in connection with any of
the transactions contemplated hereby, or (d) the failure of Company timely to
make the two remaining $75,000 payments under the Consent Judgment referred to
in Section 6.2(h). Buyer agrees to notify Sellers' Representative when such
payments have been made.

         6.5 TIME LIMITATIONS. Original Shareholders will have no liability (for
indemnification or otherwise) with respect to any representation or warranty, or
covenant or obligation to be performed and complied with on or before the
Effective Date, other than those in Sections 3.3, 3.6, 3.11, 3.13, 3.19, 3.21,
3.23 and 3.30 and those in Section 3A unless within twelve (12) months following
the Effective Date Buyer notifies Original Shareholders of a claim specifying
the factual basis of that claim in reasonable detail to the extent then known by
Buyer; a claim with respect to Sections 3.3, 3.6, 3.11, 3.13, 3.19, 3.21, 3.23
or 3.30 or with respect to Section 3A or a claim for indemnification or
reimbursement not based upon any representation or warranty or any covenant or
obligation to be performed and complied with on or before the Effective Date
(including claims for indemnification under clauses (f) through (j) of Section
6.2), may be made at any time. Buyer will have no liability (for indemnification
or otherwise) with respect to any representation or warranty, or covenant or
obligation to be performed and complied on or before the Effective Date, unless
within twelve (12) months following the


                                       39
<PAGE>

Effective Date Original Shareholders notify Buyer of a claim specifying the
factual basis of that claim in reasonable detail to the extent then known by
Original Shareholders.

         6.6 BASKET LIMITATION AND CAP.

                  (a) Original Shareholders will have no liability (for
indemnification or otherwise) with respect to the matters described in clause
(a) or clause (b) of Section 6.2 until the total of all Damages with respect to
such matters exceeds One Hundred Thousand Dollars ($100,000) (the "Basket"), and
then only for the amount by which such Damages exceed One Hundred Thousand
Dollars ($100,000). Original Shareholders will have liability with respect to
the matters described in clause (c), clause (d), clause (e), clause (f), clause
(g), clause (h), clause (i), and clause (j) of Section 6.2 without benefit of
the Basket or other threshold as to the amount thereof.

                  (b) Each Seller shall have liability for Breach of the
Employment Agreement, if any, and the Noncompetition Agreement executed by such
Seller without benefit of the Basket or other threshold as to the amount
thereof. The liability of each Seller under the Employment Agreement, if any,
and, subject to the provisions of Section 6.6(d), the Noncompetition Agreement
executed by such Seller, shall be several only and not joint and several.

                  (c) Except as provided below, the liability of each Original
Shareholder with respect the matters described in Section 6.2 and matters
arising under the Employment Agreement, if any, and the Noncompetition Agreement
executed by such Seller shall in no event exceed, in the aggregate, Three
Million Four Hundred Fifty Thousand Dollars ($3,450,000), it being the intent of
the parties that the aggregate liability of all Original Shareholders with
regard to such matters shall not exceed Thirteen Million Eight Hundred Thousand
Dollars ($13,800,000). Any payment made by the Original Shareholders to Buyer
pursuant to this Section 6 shall be deemed a reduction in the Purchase Price and
shall not be deemed to be an item of income or expense, and all parties hereto
agree to prepare their tax returns consistent therewith. Notwithstanding
anything contained in this Section 6.6 to the contrary, the limitations on
liability contained in this Section 6.6(c) shall not be effective with regard to
any willful misrepresentation herein or any intentional Breach of any covenant
or obligation under the Noncompetition Agreement.

                  (d) Nothing in Sections 6.6(b) or 6.6(c) of this Agreement
shall be construed in any way to limit the right of Buyer to make a claim
against, and seek indemnity from, the Escrow Fund, as defined in the Escrow
Agreement, for the full amount of any Damages sustained by the Buyer and to
which Buyer is entitled pursuant to this Article 6 to the extent that the Escrow
Fund is sufficient to satisfy Buyer's claim. To the extent that Buyer has a
claim for Damages in excess of the Escrow Fund, the provisions of Section 6.6(b)
shall apply. In computing the maximum amount of Damages payable by any Seller
pursuant to Section 6.6(c), any payments from the Escrow Fund shall be deemed to
have been paid proportionately by the Original Shareholders, based on their
respective ownership of the Shares. Notwithstanding the foregoing, Buyer shall
not be entitled to make a claim against, or seek indemnity from, the Escrow Fund
for Damages which arise solely in connection with (i) any Breach of the


                                       40
<PAGE>

Employment Agreements or (ii) any Breach of the Noncompetition Agreement of
Nelson; but Buyer shall be entitled to make a claim against, and seek indemnity
from, the Escrow Fund for the full amount of any Damages sustained by Buyer in
connection with any Breach of the Noncompetition Agreements of John Fleischmann,
George W. Kenaston, David Bennet and Robert Einzig or any one or more of them.

         6.7 BASKET LIMITATION FOR BUYER. Buyer will have no liability (for
indemnification or otherwise) with respect to the matters described in clause
(a) or (b) (except for payment of the Purchase Price) of Section 6.4 until the
total of all Damages with respect to such matters exceeds One Hundred Thousand
Dollars ($100,000), and then only for the amount by which such Damages exceed
One Hundred Thousand Dollars ($100,000). Buyer will have liability with respect
to matters described in clause (c) of Section 6.4 without threshold as to the
amount thereof.

         6.8 PROCEDURE FOR INDEMNIFICATION-THIRD PARTY CLAIMS.

                  (a) Promptly after receipt by an indemnified party under
Section 6.2, 6.4, or (to the extent provided in the last sentence of Section
6.3) Section 6.3 of notice of the commencement of any Proceeding against it,
such indemnified party will, if a claim is to be made against an indemnifying
party under such Section, give notice to the indemnifying party of the
commencement of such claim, but the failure to notify the indemnifying party
will not relieve the indemnifying party of any liability that it may have to any
indemnified party pursuant to this Section 6.8, except to the extent that the
indemnifying party demonstrates that the defense of such action is prejudiced by
the indemnifying party's failure to give such notice.

                  (b) If any Proceeding referred to in Section 6.8(a) is brought
against an indemnified party and it gives notice to the indemnifying party of
the commencement of such Proceeding, the indemnifying party will, unless the
claim involves Taxes, be entitled to participate in such Proceeding and, to the
extent that it wishes (unless (i) the indemnifying party is also a party to such
Proceeding and the indemnified party determines in good faith that joint
representation would be inappropriate, or (ii) the indemnifying party fails to
provide reasonable assurance to the indemnified party of its financial capacity
to defend such Proceeding and provide indemnification with respect to such
Proceeding), to assume the defense of such Proceeding with counsel satisfactory
to the indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Section 6 for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding, in
each case subsequently incurred by the indemnified party in connection with the
defense of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying
party without the indemnified party's consent unless (A) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that


                                       41
<PAGE>

may be made against the indemnified party, and (B) the sole relief provided is
monetary damages that are paid in full by the indemnifying party; and (iii) the
indemnified party will have no liability with respect to any compromise or
settlement of such claims effected without its consent. If notice is given to an
indemnifying party of the commencement of any Proceeding and the indemnifying
party does not, within ten days after the indemnified party's notice is given,
give notice to the indemnified party of its election to assume the defense of
such Proceeding, the indemnifying party will be bound by any determination made
in such Proceeding or any compromise or settlement effected by the indemnified
party.

                  (c) Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, by notice to the indemnifying party,
assume the exclusive right, at the indemnifying party's cost and expense, to
defend, compromise, or settle such Proceeding, but the indemnifying party will
not be bound by any determination of a Proceeding so defended or any compromise
or settlement effected without its consent (which may not be unreasonably
withheld).

                  (d) Each Original Shareholder hereby consents to the
non-exclusive jurisdiction of any court in which a Proceeding is brought against
any Indemnified Person for purposes of any claim that an Indemnified Person may
have under this Agreement with respect to such Proceeding or the matters alleged
therein, and agree that process may be served on Original Shareholders with
respect to such a claim anywhere in the world.

         6.9 PROCEDURE FOR INDEMNIFICATION-OTHER CLAIMS. A claim for
indemnification for any matter not involving a third-party claim may be asserted
by notice to the party from whom indemnification is sought.

         6.10 NOTICE TO ORIGINAL SHAREHOLDERS. Any notice to all Original
Shareholders pursuant to this Section 6 shall be sent to the attention of the
Sellers' Representative, and notice sent to the Sellers' Representative shall be
deemed sufficient notice to all Original Shareholders under this Section 6.

         6.11 ESCROW. Buyer may assert a claim for indemnification under the
Escrow Agreement by notice to Sellers' Representative and the Escrow Agent
specifying in reasonable detail the basis for such claim to the extent then
known by Buyer and the amount to which Buyer is entitled under this Section 6,
all as more fully provided in the Escrow Agreement. Except as provided in
Section 6.6(d), Buyer is authorized to recover from the funds in escrow the
entire amount of, or any portion of, any claim against any Seller without regard
to the amount contributed or deemed to be contributed by such Seller. Sellers
will settle among themselves any right to contribution or indemnity with regard
to amounts paid to Buyer from the escrowed funds. The amount held in escrow, if
and when disbursed to Sellers, shall be treated on an installment sale basis and
shall be taken into income by Sellers in the year in which it is received.
Subject to the provisions of Section 6.6(c), neither the giving of notice of a
claim under the Escrow


                                       42
<PAGE>

Agreement nor the failure to give such notice will constitute an election of
remedies or limit Buyer in any manner in the enforcement of any other remedies
that may be available to it.

         6.12 TAX BENEFIT. In determining the amount of any Damages under this
Section 6, such amount shall take into account any net tax benefit (federal,
state, local or personal property) actually realized by the indemnified party
from the incurrence or payment by the indemnified party of such Damages. In
connection with the determination of such net tax benefit, (i) tax costs
actually incurred, if any, included in the calculation of Damages or from the
indemnification shall also be taken into account; (ii) the net tax benefit and
the tax costs will be taken into account only to the extent actually realized
with respect to the tax return prepared relative to the tax year in which the
indemnification is due; and (iii) any reduction in the basis of the Shares or
underlying assets as a result of the receipt of payment for Damages shall not be
deemed to be a tax benefit or a tax cost to Buyer. The determination of any tax
benefit or tax cost shall be made by the indemnified party's independent
certified public accountants, whose determination shall be final, binding and
conclusive on all parties.

         7. GENERAL PROVISIONS.

         7.1 EXPENSES. Except as otherwise expressly provided in this Agreement,
each party to this Agreement will bear its respective expenses incurred in
connection with the preparation, execution, and performance of this Agreement
and the transactions contemplated hereby, including all fees and expenses of
agents, representatives, counsel, and accountants. Subject to the provisions of
Section 2.6(a), the Company may pay the Sellers' out-of-pocket expenses in
connection with this Agreement.

         7.2 PUBLIC ANNOUNCEMENTS. Any public announcement or similar publicity
with respect to this Agreement or the transactions contemplated hereby will be
issued, if at all, at such time and in such manner as Buyer determines. Sellers
and Buyer will consult with each other concerning the means by which the
Company's employees, customers, and suppliers and others having dealings with
the Company will be informed of the transactions contemplated hereby, and Buyer
will have the right to be present for any such communication. Notwithstanding
the foregoing, Buyer shall have the right to make such disclosure as it deems
necessary or advisable under the Federal securities laws, in which event Buyer
shall provide Seller with a copy of such disclosure.

         7.3 CONFIDENTIALITY. The Confidentiality Agreement dated April 17,
2001, by and between the parties, is hereby declared to be terminated and of no
further force and effect.

         7.4 NOTICES. All notices, consents, waivers, and other communications
under this Agreement must be in writing and will be deemed to have been duly
given (a) when delivered by hand (with written confirmation of receipt), (b)
when sent by telecopier (upon written confirmation of receipt by the recipient),
provided that a copy is mailed by registered mail, return receipt requested, or
(c) when received by the addressee (or on the date on which delivery is refused
if the addressee refuses delivery, or on the first date on which delivery is
attempted if delivery is otherwise not possible at the address provided for
notice), if sent by Express Mail or a

nationally recognized overnight delivery service which provides evidence of

Representative, and any notice sent to the Sellers' Representative shall be
deemed notice to all Sellers:

are cumulative and not alternative. Neither the failure nor any delay by any
party in exercising any right, power, or privilege under this Agreement or the
documents referred to in this Agreement will operate as a waiver of such right,
power, or privilege, and no single or partial exercise of any such right, power,
or privilege will preclude any other or further exercise of such right, power,
or privilege or the exercise of any other right, power, or privilege. To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement or the documents referred to in this Agreement can be discharged

right unless in writing signed by the other party; (b) no waiver that may be
given by a party will be applicable except in the specific instance for which it
is given; and (c) no notice to or demand on one party will be deemed to be a
waiver of any obligation of such party or of the right of the party giving such
notice or demand to take further action without notice or demand as provided in
this Agreement or the documents referred to in this Agreement.

         7.7 ENTIRE AGREEMENT AND MODIFICATION. This Agreement supersedes all
prior agreements between the parties with respect to its subject matter and
constitutes (along with the documents referred to in this Agreement) a complete
and exclusive statement of the terms of


                                       44

the agreement between the parties with respect to its subject matter. This
Agreement may not be amended except by a written agreement executed by the party
to be charged with the amendment.

         7.8 SELLERS' REPRESENTATIVE. Each Seller irrevocably appoints John
Fleischmann (the "Sellers' Representative") as his, her or its agent, proxy and
attorney-in-fact for all purposes under this Agreement, and each Seller
authorizes the Sellers' Representative to do any and all of the following for
the Seller and in the Seller's name and stead: (i) to execute, acknowledge, as
appropriate, and deliver to Buyer any certificate, document or agreement
referred to herein or contemplated hereby, including this Agreement, the Shares,

funds or other amounts owing to the Seller hereunder; (iii) to represent,

Accountants with respect thereto; (iv) to execute, acknowledge, as appropriate,
and deliver such modifications and amendments to this Agreement or Sellers'
Closing Documents as the Sellers' Representative shall deem advisable in his
discretion; and (v) to do any and all other acts and things in connection with

with an interest; Buyer shall be entitled to rely upon the powers granted herein
with respect to any matter relating to this Agreement; and any question which
may arise concerning the power or authority of the Sellers' Representative to
act for each Seller shall be interpreted and construed in favor of the authority
of the Sellers' Representative.

         7.9 DISCLOSURE LETTER.

                  (a) The disclosures in the Disclosure Letter, and those in any
Supplement thereto, must relate only to the representations and warranties in
the Section of the Agreement to which they expressly relate and not to any other
representation or warranty in this Agreement.

                  (b) In the event of any inconsistency between the statements
in the body of this Agreement and those in the Disclosure Letter (other than an
exception expressly set forth as such in the Disclosure Letter with respect to a
specifically identified representation or warranty), the statements in the body
of this Agreement will control.

         7.10 ASSIGNMENTS, SUCCESSORS, AND NO THIRD-PARTY RIGHTS. Neither party
may assign any of its rights under this Agreement without the prior consent of
the other parties except that Buyer may assign any of its rights under this
