conditions pursuant to which such escrow fund will be established and
maintained;

         NOW, THEREFORE, the parties hereto hereby agree as follows:

         1. General.

            (a) The Escrow Agent is hereby constituted and appointed the
escrow agent hereunder.

            (b) The Stock Purchase Agreement by this reference is
incorporated herein and made a part of this Agreement to the same extent as
if its terms were fully set forth herein. Except as otherwise defined
herein, capitalized terms used herein shall have the meaning given to them
in the Stock Purchase Agreement, provided, however, that the Escrow Agent
shall not be charged with knowledge thereof nor subject in any way to the
terms and conditions thereof.

         2. Appointment of Stockholders' Representatives. The Stockholders
hereby appoint The Stockholders' Representatives as their representatives
for purposes of this Agreement with the power and authority set forth in
subparagraph 8(c) below.

         3. Escrow and Indemnification.

            (a) Escrow Fund. Simultaneously with the execution of this
Agreement, the Stockholders shall deposit with the Escrow Agent, by wire
transfer or delivery of checks payable to the Escrow Agent, the sum of
$2,500,000 (the "Escrow Amount") to an account (the "Escrow Account")
designated by the Escrow Agent. The Escrow Account shall be increased by
any interest or other amount received with respect thereto and any
compounding interest or other return (collectively, "Interest") and
decreased by the distributions provided for in Sections 4 and 6 hereof. The
amounts in the Escrow Account from time to time, but not including any
Interest (whether or not still in the Escrow Account), are hereinafter
referred to as the "Escrow Fund". The Escrow Agent agrees to hold, invest
and otherwise act with respect to the Escrow Fund and any Interest earned
thereon in accordance with the terms and conditions of this Agreement The
Escrow Agent shall invest the Escrow Fund and any Interest received thereon
contained in the Escrow Account as directed by instruction of the
Representative, in Permitted Investments (as defined in Section 5 herein)
from time to time during the term of this Agreement. The Escrow Agent
hereby acknowledges receipt of such sum. The Escrow Agent agrees to hold
the Escrow Fund in an escrow account subject to the terms and conditions of
this Agreement.

            (b) Indemnification. The Stockholders have agreed in Section 10
of the Stock Purchase Agreement, to indemnify and hold harmless the Buyer
from and against specified Losses (as defined in Section 10 of the Stock
Purchase Agreement). The Escrow Fund shall be security for such indemnity
obligation of the Stockholders, subject to the limitations, and in the
manner provided, in this Agreement.

            (c) Transferability. The respective interests of the
Stockholders in the Escrow Fund shall not be assignable or transferable,
other than by operation of law. Notice of any such assignment or transfer
by operation of law shall be given to the Escrow Agent and the Buyer, and
no such assignment or transfer shall be valid until such notice is given.

         4. Disbursement of Escrow Fund.

            (a) Disbursement by Escrow Agent. The Escrow Agent shall
disburse the Escrow Fund only in accordance with (i) a written instrument
delivered to the Escrow Agent that is executed by both the Buyer, on the
one hand, and the Stockholders' Representatives, on the other hand and that
instructs the Escrow Agent as to the disbursement of some or all of the
Escrow Fund, (ii) an order of a court of competent jurisdiction, which is
final and with respect to which all applicable appeal periods have expired
or which is non-appealable, a copy of which is delivered to the Escrow
Agent by either the Buyer or the Stockholders' Representatives, that
instructs the Escrow Agent as to the disbursement of some or all of the
Escrow Fund, or (iii) the provisions of Section 4(b) hereof. The Buyer and
the Stockholders' Representatives agree to cooperate with each other in
good faith to comply with the provisions of this Section 4 and to use
reasonable efforts to resolve any disputes relating to the distribution
from the Escrow Account.

business days after October 14, 2001 (the "Termination Date"), the Escrow
Agent shall distribute to the Stockholders all of the Escrow Fund then held
in escrow. Notwithstanding the foregoing, if the Buyer has previously
delivered to the Escrow Agent a copy of a Claim Notice (as defined in
Section 10.02 of the Stock Purchase Agreement) and the Escrow Agent has not
received written notice of the resolution of the claim covered thereby, the
Escrow Agent shall retain in escrow after the Termination Date an amount
equal to the amount stated in such Claim Notice. Any funds so retained in
escrow shall be disbursed only in accordance with the terms of clauses (i)
or (ii) of Section 4(a) hereof.

            (c) Method of Disbursement. Any distribution of all or a
portion of the Escrow Fund to the Stockholders shall be made in accordance
with the percentages set forth opposite the stockholders' respective names
on Schedule I. Distributions to the Stockholders shall be made by mailing
checks to such stockholders at their respective addresses shown on Schedule
I (or such other address as may be provided in writing to the Escrow Agent
by any such stockholder).

         5. Investment of Escrow Fund.

            (a) Permitted Investments. Any monies held in the Escrow Fund
shall be invested by the Escrow Agent, to the extent permitted by law and
as directed by the Stockholders' Representatives, in (i) obligations issued
or guaranteed by the United States of America or any agency or
instrumentality thereof having maturities of two months or less from the
date of acquisition, (ii) obligations (including certificates of deposit
and bankers' acceptances) of banks which at the date of their last public
reporting had total assets in excess of $500,000,000, (iii) commercial
paper rated at least A-1 or the equivalent thereof by Standard & Poor's

some or all of the securities described in the foregoing clauses (i), (ii)
and (iii).

reporting purposes, all interest or other income earned from the investment
of the Escrow Fund or any portion thereof shall be allocable to the party
which ultimately receives such Escrow Fund or portion thereof.

            (c) Certification of Tax Identification Number. The parties
hereto agree to provide the Escrow Agent with a certified tax
identification number by signing and returning a Form W-9 to the Escrow

Escrow Fund is credited to such Escrow Fund. The parties hereto understand

from the Escrow Fund (up to the amount then available in the Escrow Fund)
to the party to whom such amount is owed in satisfaction of such
indemnification obligations of the Stockholders; provided that if the Buyer
delivers to the Escrow Agent (with a copy to the Stockholders'
Representatives), within five business days after delivery of such notice

         10. Creditors.

security interest in all of the grantor's rights, title and interest in and
to the Escrow Account and any proceeds thereof (as such term is defined in

Escrow Account and/or such proceeds on behalf of the Company and the
Sellers but subject to the terms and conditions set forth in this
Agreement. The Company and the Sellers further agree to take any and all
necessary additional steps to perfect and continue perfection of the
security interests granted hereunder. Notwithstanding the foregoing, the
Escrow Agent shall have a first perfected security interest in and prior
lien upon all property held by it under this Escrow Agreement but solely in

unavailable or unwilling to continue in its capacity herewith, the Escrow
Agent may resign and be discharged from its duties or obligations hereunder
by delivering a resignation to the parties to this Escrow Agreement, not
less than 60 days' prior to the date when such resignation shall take
effect. The Buyer may appoint a successor Escrow Agent without the consent
of the Stockholders' Representatives so long as such successor is a bank
with assets of at least $500 million, and may appoint any other successor
Escrow Agent with the consent of the Stockholders' Representatives, which
shall not be unreasonably withheld. If, within such notice period, the
Buyer provides to the Escrow Agent written instructions with respect to the
appointment of a successor Escrow Agent and directions for the transfer of
any Escrow Fund then held by the Escrow Agent to such successor, the Escrow
Agent shall act in accordance with such instructions and promptly transfer
such Escrow Fund to such designated successor. If no successor Escrow Agent
