Agreement” included reference to this Amendment No. 3 and (b) immediately after giving effect to the waiver set forth in Section 3 above, no Default shall have occurred and be continuing.

                         Section 5. Conditions Precedent. The amendments to the Credit Agreement set

<PAGE>

               (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), 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.

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

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 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;
<PAGE>

               (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 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,

<PAGE>

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, 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
<PAGE>

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.

               (c)    INTENTIONALLY OMITTED.

        3.7    INTENTIONALLY OMITTED

        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.
<PAGE>

                             (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
Sellers or the Company, except such Taxes, if any, as are listed in Part 3.11 of
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 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.
<PAGE>

        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

which the Company has otherwise participated or to which the Company has
contributed (or to which the Company is or was required to contribute under any
Legal Requirement) for the benefit of or in which any employee, terminated
employee, director, or independent contractor participates. The plans,
agreements, arrangements and commitments listed or required to be listed in Part
3.13 of the Disclosure Letter are referred to collectively as the "Company

to Buyer correct and complete copies of the plan documents and plan summary
descriptions, the most recent determination letter received from the IRS, the
most recent Form 5500 Annual Report, and all related agreements and contracts,

Part 3.13 of the Disclosure Letter.

               (d)    Each Company Plan can be terminated within sixty (60)

vesting or acceleration of any benefits promised by such Plan.

               (e)    With the exception of an agreement, dated July 5, 2001,
between the Company and Joan Bowles, no Company Plan obligates the Company to
pay separation, severance, termination or similar benefits as a result of any

the circumstances in which they were made, not misleading.
<PAGE>

               (b)    There is no fact known to any Original Shareholder that
has specific application to any Seller or the Company (other than general
economic or industry conditions) and that materially adversely affects or, as
far as such Original Shareholders can reasonably foresee, materially threatens,
the assets, business, prospects, financial condition, or results of operations
of the Company, that has not been set forth in this Agreement or the Disclosure
Letter.

        3.25   RELATIONSHIPS WITH RELATED PERSONS. Except as to the use of a
portion of the IPT CD Rom by David Bennet as referenced in, and pursuant to, the
Noncompetition Agreement between David Bennet and Buyer of even date, no Seller
or any Related Person of any Seller or of the Company has, or since the first
day of the next to last completed fiscal year of the Company has had, any
interest in any property (whether real, personal, or mixed and whether tangible
or intangible), used in or pertaining to the Company's businesses. No Seller or
any Related Person of any Seller or of the Company is, or since the first day of
the next to last completed fiscal year of the Company has owned (of record or as
a beneficial owner) an equity interest or any other financial or profit interest
in, a Person that has (i) had business dealings or a material financial interest
in any transaction with the Company, or (ii) engaged in competition with the

Company is a party to any Contract with, or has any claim or right against, the
Company.

        3.26   BROKERS OR FINDERS. Sellers and their agents have incurred no
obligation or liability, contingent or otherwise, for brokerage or finders' fees
or agents' commissions or other similar payment in connection with this
Agreement other than professional fees of any nature paid to Galland, Kharasch,
Greenberg, Fellman & Swirsky, P.C. which shall be paid immediately prior to
Closing.

        3.27   BUSINESS RELATIONSHIPS. Part 3.27 of the Disclosure Letter
contains a complete and accurate list of each customer of the Company that
accounted for more than three percent (3%) of the total revenues of the Company
in each of the last three (3) fiscal years of the Company and in the last fiscal
period included in the Financial Statements, and sets forth the total revenues
derived from each such customer during each of such fiscal periods. To the
Knowledge of the Company or Original Shareholders, since the date of the Balance
Sheet, the Company has not suffered any loss of employees or suffered loss of
good will or an adverse change in the relationship with any suppliers,
customers, creditors, agents or others having business relationships with the
Company that materially and adversely affects the business operations or
prospects of the Company. Except as set forth in Part 3.27 of the Disclosure
Letter, the Company has not been involved in any material controversy with any
of its customers or suppliers. The Company has not been advised by any of its
customers or suppliers that such customer or supplier was or is intending to
terminate its relationship with the Company or would not continue to purchase
supplies or services for future periods on account of any dissatisfaction with
the Company's performance or due to the Contemplated Transactions. To the
Knowledge of the Company or Original Shareholders, all business placed by all
employees of the Company
<PAGE>

has been placed in the name of the Company, and all fees and compensation on
such business have been paid to and are the property of the Company.

        3.28   INDEBTEDNESS BY RELATED PERSONS. To Original Shareholders' or the
Company's Knowledge, all indebtedness heretofore owed to the Company by any
Seller or any Related Person of any Seller has been paid in full. All
indebtedness by the Company to any Seller or Former Shareholder or any Related
Person of any of them, (including any right to indemnification or reimbursement
from the Company, whether pursuant to the Company's Organizational Documents,
contract or otherwise and whether or not relating to claims pending on, or
asserted after, the Effective Date) will be released at the Closing and the
Company will not have any obligation with respect thereto. All such obligations
of the Company are listed on Part 3.28 of the Disclosure Letter.

        3.29   CERTAIN PROCEEDINGS. There is no Proceeding that has been
commenced against any Seller or the Company that challenges, or may have the
effect of preventing, delaying, making illegal, or otherwise interfering with,
any of the Contemplated Transactions. To Original Shareholders' or the Company's
Knowledge, no such Proceeding has been Threatened.

        3.30   SHAREHOLDER AGREEMENTS; FORMER SHAREHOLDERS. Immediately
preceding the Closing, Two Hundred Fourteen (214) shares of the issued and
outstanding Class A voting common stock and Two Thousand Eighteen (2,018) shares
of the issued and outstanding Class B non-voting common stock were owned,
beneficially and of record, by the individuals (collectively, the "Former
Shareholders" and each, a "Former Shareholder") and in the amounts set forth on
Part 3.30 of the Disclosure Letter. Since the date of the Balance Sheet, no
Person has owned or held any equity securities of the Company other than Sellers
and the Former Shareholders. Pursuant to appropriate purchase agreements (the
"Cross Purchase Agreements") and concurrently with the Closing, Original
Shareholders have acquired all of the Shares previously owned by the Former
Shareholders and at Closing will convey to Buyer all of the issued and
outstanding Shares of the Company, free and clear of all Encumbrances, including
any claim or interest of the Former Shareholders. With the exception of the
Cross Purchase Agreement, all Stockholders' Buy-Sell Agreements, Stock Bonus
Agreements, Stock Repurchase Agreements, or other Contracts which relate to the
securities of the Company and to which the Company, the Sellers, and Former
Shareholders or any one or more of them is a party, have been fully and finally
terminated and are no longer of any force or effect. Each of the Former
Shareholders has duly executed and delivered to Buyer a Former Shareholder's
Release, and the Former Shareholder's Release executed by such Former
Shareholder constitutes the legal, valid and binding obligation of such Former
Shareholder, enforceable against such Former Shareholder in accordance with its
terms. Except as set forth in Part 3.30 of the Disclosure Letter, no Former
Shareholder and no Related Person of any Former Shareholder, is a party to any
Contract with, or has any claim or right against, the Company or any of the
Company's securities.

        Each of the Sellers, individually with respect to himself, herself or

behalf of such Seller and delivered to Buyer pursuant to this Agreement
(collectively, the "Seller's Closing Documents") and this Agreement constitute

deliver this Agreement and the Seller's Closing Documents and to perform the
Seller's obligations under this Agreement and the Seller's Closing Documents.

               (b)    Neither the execution and delivery of this Agreement nor
the consummation or performance of the transactions contemplated hereby will,
directly or indirectly (with or without notice or lapse of time) 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 Seller may be subject.

        3A.2   POWERS. Part 3A.2 of the Disclosure Letter contains a complete
and accurate list, and the Seller has heretofore delivered or made available to
Buyer a true and complete copy of, each power of attorney that is currently
effective and outstanding granted by the Seller with respect to any of the
Shares.

        3A.3   RELATED PARTY TRANSACTIONS

               (a)    Neither the Seller nor any Related Person of the Seller
has or may acquire any rights under, or has or may become subject to any
obligation or liability under, any Contract that relates to the business of, or
any of the assets owned or used by, the Company.

               (b)    Except as set forth in Part 3A.3 of the Disclosure Letter,

Contract with, or has any claim or right against, the Company.

        3A.4   DISCLOSURE. There is no fact known to the Seller that has any
specific application to the Seller or to the Company (other than general
economic or industry conditions) and that materially and adversely affects or,

<PAGE>

materially threatens, the assets, business, prospects, financial condition or
results of operations of the Company, that has not been set forth in this
Agreement or the Disclosure Letter.

        3A.5   INDEBTEDNESS BY RELATED PERSONS. All indebtedness heretofore owed

obligation with respect thereto. All such obligations of the Company are listed
on Part 3.28 of the Disclosure Letter.

        3A.6   SHARES. The Seller is the sole record and beneficial owner of the

by the Seller other than an investment legend pursuant to the Securities Act.
The Seller is not a party to any option, warrant, purchase right or other
contract or commitment that would require the Seller to sell, transfer or
otherwise dispose of any of the Shares other than this Agreement. The Seller is
not a party to any voting trust, proxy or other agreement or understanding with
respect to the voting of any of the Shares. All of the Shares heretofore owned
by the Seller have been duly endorsed for transfer to Buyer or are accompanied
by duly executed stock powers.

        3A.7   BROKERS OR FINDERS. The Seller and his or her agents have
incurred no obligation or liability, contingent or otherwise, for brokerage or
finders' fees or agents' commissions or other similar payment in connection with
this Agreement other than professional fees of any nature paid to Galland,
Kharasch, Greenberg, Fellman & Swirsky, P.C. which shall be paid immediately
prior to Closing.

        4.     REPRESENTATIONS AND WARRANTIES OF BUYER.

        Buyer represents and warrants to Sellers as follows:

        4.1    ORGANIZATION AND GOOD STANDING.  Buyer is a corporation duly
organized, validly existing, and in good standing under the laws of the State of
Delaware.

        4.2    AUTHORITY; NO CONFLICT.

               (a)    This Agreement constitutes the legal, valid, and binding
obligations of Buyer, enforceable against Buyer in accordance with its terms.
Buyer has the absolute and unrestricted right, power, and authority to execute
and deliver this Agreement and to perform its obligations hereunder.

               (b)    Neither the execution and delivery of this Agreement by
Buyer nor the consummation or performance of any of the Transactions
contemplated hereby by Buyer will give any Person the right to prevent, delay,
or otherwise interfere with any of the Transactions contemplated hereby. Buyer
is not and will not be required to obtain any Consent from any
<PAGE>

Person in connection with the execution and delivery of this Agreement or the
consummation or performance of any of the Transactions contemplated hereby.

        4.3    INVESTMENT INTENT.  Buyer is acquiring the Shares for its own
account and not with a view to their distribution within the meaning of Section
2(11) of the Securities Act.

        4.4    CERTAIN PROCEEDINGS. There is no pending Proceeding that has been
commenced against Buyer and that challenges, or may have the effect of
preventing, delaying, making illegal, or otherwise interfering with, any of the
Transactions contemplated hereby. To Buyer's Knowledge, no such Proceeding has
been Threatened.

        4.5    BROKERS OR FINDERS. Buyer and its agents have incurred no
obligation or liability, contingent or otherwise, for brokerage or finders' fees
or agents' commissions or other similar payment in connection with this
Agreement.

        5.     COVENANTS.

        5.1    PROTECTION OF RELATIONSHIPS. None of the Sellers will at any time
hereinafter take, and they and each of them will cause the Company not to take,
any action that is designed or intended to have the effect of discouraging any
lessor, licensor, customer, supplier or other business associate of the Company
from establishing or maintaining business relationships with the Company.

        5.2    FURTHER ASSURANCES. Sellers shall use Sellers' best efforts to
implement the provisions of this Agreement, and for such purpose Sellers, at the
request of Buyer and at no cost to Sellers, at or after the Closing, shall,
without further consideration, promptly execute and deliver, or cause to be
executed and delivered, to Buyer such documents and other instruments in
addition to those required by this Agreement, in form and substance satisfactory
to Buyer, and take all such other actions, as Buyer may reasonably deem
necessary or desirable to implement any provision of this Agreement and/or to
further the transactions contemplated by this Agreement and obtain the benefit
thereof for Buyer. Sellers will take no action to terminate or limit existing or
prior coverages as applicable to the pre-closing activities of the Company or
the Company's ability to make claims under those coverages.

        5.3    INTENTIONALLY OMITTED.

        5.4    CONFIDENTIALITY AGREEMENT OF SELLERS. Each Seller acknowledges
and agrees that all Confidential Information known or obtained by the Seller,
whether before or after the date hereof, is the property, as appropriate, of the
Company or the Buyer. Therefore, each Seller agrees that the Sellers will not,
at any time, disclose to any unauthorized Persons or use for his own account or
for the benefit of any third party any Confidential Information, whether Sellers
have such information in Sellers' memories or embodied in writing or other
<PAGE>

physical form or any computer readable format, without Buyer's written consent,
unless and to the extent that the Confidential Information (i) is or becomes
generally known to and available for use by the public other than as a result of
Sellers' fault or the fault of any other Person bound by a duty of
confidentiality to Buyer or the Company or, (ii) becomes available to Seller on
a non-confidential basis, from a source other than the Company or any of its
employees who are entitled to disclose such information without breach of
confidentiality to the Company; or (iii) to the extent that disclosure is
required by law (in which event Sellers shall give Buyer as much notice of such
disclosure as is practicable and permitted by law and shall cooperate with Buyer
at Buyer's expense to obtain appropriate protective orders). Each Seller agrees
to deliver to Buyer at the time of execution of this Agreement, and at any other
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, 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,
<PAGE>

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 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.
<PAGE>

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
and assets (whether real, personal, or mixed and whether tangible or intangible)

conducted by Sellers or the Company or by any other Person for whose conduct
they are or may be held responsible; or

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

to which indemnity may be sought under this Section 6.3. The procedure described

<PAGE>

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 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.
<PAGE>

               (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
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.

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
<PAGE>

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 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).
<PAGE>

               (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 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.
<PAGE>

        7.1    EXPENSES. Except as otherwise expressly provided in this
Agreement, each party to this Agreement will bear its respective expenses

provisions of Section 2.6(a), the Company may pay the Sellers' out-of-pocket

publicity with respect to this Agreement or the transactions contemplated hereby

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.

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 delivery, in each case to the appropriate

provided, that any notice which is being given to all of the Sellers shall be

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
by one party, in whole or in part, by a waiver or renunciation of the claim or
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 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

appropriate, and deliver to Buyer any certificate, document or agreement
referred to herein or contemplated hereby, including this Agreement, the Shares,
and the Seller's Closing Documents; (ii) to accept, receipt for and deposit any
funds or other amounts owing to the Seller hereunder; (iii) to represent,
negotiate on behalf of and bind the Seller in connection

discussions with the 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 this Agreement as Sellers' Representative shall deem
advisable in his discretion. The agency created hereby shall be deemed
irrevocable and coupled 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

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
Agreement to any Related Person of Buyer and further except that any of the
Sellers may sell or assign his rights to receive payment hereunder (but may not
delegate or assign any obligations or liabilities hereunder) to another Seller.
Subject to the preceding sentence, this Agreement will apply to, be binding in
all respects upon, and inure to the benefit of the heirs, personal and legal
representatives, successors and permitted assigns of the parties. Nothing
expressed or referred to in this Agreement will be construed to give any Person
other than the parties to this Agreement any legal or equitable right, remedy,
or claim under or with respect to this Agreement or any provision of this
Agreement. This Agreement and all of its provisions and conditions are for the
sole and exclusive benefit of the parties to this Agreement and their heirs,
successors and permitted assigns.

        7.11   SEVERABILITY. If any provision of this Agreement is held invalid

this Agreement will remain in full force and effect. Any provision of this

full force and effect to the extent not held invalid or unenforceable.

corresponding Section or Sections of this Agreement. All words used in this
Agreement will be construed to be of such gender or number as the circumstances
require. Unless otherwise expressly provided, the word "including" does not
limit the preceding words or terms.

        7.13   GOVERNING LAW; JURISDICTION. This Agreement shall be governed by
the laws of the State of New York, without regard to conflicts of laws
principals. Buyer and each Seller submit to the jurisdiction of any state or
federal court sitting in the State of New York in any action or proceeding
arising out of or relating to this Agreement and agree that all claims in
respect of the action or proceeding may be heard or determined in any such
court. Buyer and each Seller also agree not to bring any action or proceeding
arising out of or relating to this Agreement in any other court. Buyer and each
Seller waive any defense of inconvenient forum to the maintenance of any action
or proceeding so brought. Each Seller appoints the Sellers' Representative as
his or her agent to receive on his or her behalf service or copies of any
Summons and Complaint and any other process that might be served in such action
or proceeding.

        7.14   COUNTERPARTS. This Agreement may be executed in one or more
