                         (bb) "EBITDA" shall mean the earnings of the
Corporation and the Subsidiaries on a consolidated basis (including the G&A
Allocation), on a Stand Alone basis, before interest, taxes, depreciation and

GAAP consistently applied with prior periods, plus the Recoverable Allocations.
For purposes of calculating EBITDA, except for the G&A Allocations, all general
corporate overhead allocations imposed by Buyer and/or its Affiliates (as
hereinafter defined) on the Corporation and/or its Subsidiaries unrelated to the
actual provision of goods and services by the Corporation and its Subsidiaries

                         (ff) The "2001 EBITDA Target" shall mean $7,772,000
less the Allocation Credit for the 12 month period ending April 30, 2001.

                         (gg) "Recoverable Allocations" shall mean the general
and administrative expenses allocated by Buyer and/or its Affiliates to the
Corporation and/or the Subsidiaries for the period in question (the "G&A
Allocation"), multiplied by a fraction (the "Percent Recoverable"), the

Representative, except that the Representative shall not unreasonably object to
the G&A Allocation proposed by Buyer if such allocation will not cause the
Corporation's billing rates to exceed its then current bid rates. If the amount
of Buyer's proposed G&A Allocation for any measurement period would cause the
Corporation's billing rates to exceed its then current bid rates (as determined
by the Representative in its reasonable discretion), the Representative may
decline to agree to such proposed G&A Allocation (or the amount thereof which
the Representative so determines would result in the Corporation's billing rates
so exceeding its then current bid rates). Further, all G&A Allocations shall be
reasonable and appropriate under applicable law and governmental accounting
rules (including under applicable federal procurement cost principles and cost
accounting standards). Buyer agrees to cooperate with the Corporation and the
Subsidiaries to assure proper accounting, as well as satisfaction of record
keeping and disclosure requirements, under applicable law and governmental
accounting rules (including under applicable federal procurement cost principles

Buyer agrees to cooperate with the Corporation and the Subsidiaries to assure
proper accounting, as well as satisfaction of record keeping and disclosure
requirements, under applicable law and governmental accounting rules (including
under applicable federal procurement cost principals and cost accounting
standards).

               (H)  Within 30 days after the end of each measurement period
set forth in this subparagraph 2(a)(iii), the Representative shall prepare (or
shall cause to be prepared, including, if within the control of the
Representative, by way of causing the Corporation to prepare) a Profit and Loss
Statement for the Corporation and its Subsidiaries on a consolidated basis for
the measurement period then ended (the "P&L Statement"). Said P&L Statement
shall additionally set forth in reasonable detail, based on the information
therein, the determinations and calculations of the amounts (if any) payable by
the Buyer under subparagraphs 2(a)(iii)(A), (B), (C), (D) and/or (E), as the
case may be, with respect to said measurement period. It is anticipated by the
parties that the Corporation's books and records, including any accountant work
papers, will be within the control of the Representative (as an officer and/or
director of the Corporation) at the time such P&L Statements are to be so
prepared. However, if and to the extent not so within the control of the
Representative, then for purposes of preparing each such P&L Statement, Buyer
shall make reasonably available (and shall cause the Corporation and its
Subsidiaries to make reasonably available) to the Representative (and the
Representative's accountants, attorneys, agents, and representatives) during
normal business hours the books and records (including any accountants work
papers) of the Corporation and its Subsidiaries, upon reasonable advance notice
to the Buyer, and shall otherwise cooperate in good faith with the
Representative with respect to the preparation of said P&L Statement; provided,
however, that the Representative shall schedule such access

                                      -8-
<PAGE>

through an authorized representative of Buyer and in such a way as to avoid
material disruption of the normal business operations of the Corporation. For a
period of 60 days after receipt by Buyer of the P&L Statement, Buyer shall have
the right to review or audit such P&L Statement. For purposes of reviewing or
auditing such P&L Statement, if and to the extent not within the control of the
Buyer, the Representative (if and to the extent within the control of the
Representative and/or other Stockholders) shall make available to the Buyer (and
the Buyer's accountants, attorneys, agents and representatives) during normal
business hours the books and records (including any work papers used by the
Representative to prepare the P&L Statement) of the Corporation and its
Subsidiaries, upon reasonable advance notice to the Representative, and shall
otherwise cooperate in good faith with the Buyer's review or audit of said P&L
Statement; provided, however, that Buyer shall schedule such access through the
Representative and in such a way as to avoid material disruption of the normal
business operations of the Corporation. Unless the Representative shall receive
notice from the Buyer within such 60 day period to the effect that Buyer
disputes one or more items in the P&L Statement (including the determinations or
calculations of the amounts, if any, payable by the Buyer under subparagraphs
2(a)(iii)(A), (B), (C), (D) and/or (E), as the case may be, with respect to said
measurement period), the P&L Statement (including the determinations and
calculations of the amounts, if any, payable by the Buyer under subparagraphs
2(a)(iii)(A), (B), (C), (D) and/or (E), as the case may be, with respect to said
measurement period) shall become final, conclusive and binding on all parties
hereto, and the Buyer shall pay the amounts, if any, payable by the Buyer under
subparagraphs 2(a)(iii)(A), (B), (C), (D) and/or (E), as the case may be, within
5 business days of the expiration of said 60 day period. Any such notice from
the Buyer to the Representative disputing one or more items in the P&L Statement
as aforesaid shall specify in reasonable detail the

                                      -9-
<PAGE>

nature and amount of said dispute or disputes, and the amount, if any, payable
by the Buyer under subparagraphs 2(a)(iii)(A), (B), (C), (D) and/or (E), as the
case may be, with respect to said measurement period which the Buyer does not
dispute. If the Representative receives notice from the Buyer within the
aforementioned 60 day period that Buyer disputes one or more items in the P&L
Statement (including the determinations or calculations of the amounts, if any,
payable by the Buyer under subparagraphs 2(a)(iii)(A), (B), (C), (D) and/or (E),
as the case may be, with respect to said measurement period), then (i) such
dispute shall be resolved in accordance with the procedures set forth in
subparagraph 2(b)(iii) hereunder, and any payments due Stockholders under this
subparagraph 2(a)(iii) which are subject to such dispute shall be due and
payable 5 business days after the resolution of such dispute pursuant to
subparagraph 2(b)(iii), and (ii) the Buyer, if and to the extent the Buyer has
not disputed an amount payable by the Buyer under subparagraphs 2(a)(iii)(A),
(B), (C), (D) and/or (E), as the case may be, with respect to said measurement
period as aforesaid, shall pay said undisputed amount within 5 business days of
the expiration of the 60 day review and audit period set forth in this
subparagraph 2(a)(iii)(H).

                    (I)  Any payment due to the Stockholders from the Buyer
pursuant to this subparagraph 2(a)(iii) shall be made by good check mailed to,
or by wire transfer pursuant to instructions provided at least 5 days prior to
the date on which Buyer makes payment to, the Representative. Such payments
shall be made pursuant to, and shall be held, applied, invested, reinvested and
disbursed in accordance with, the Stockholders' Escrow Agreement.

          (b)  (i)  It is the intention of the parties that (1) the
Corporation's Net Worth (as hereinafter defined) at the Closing (the "Closing
Net Worth") be equal to or greater than $10,330,247, and (2) the Corporation's
debt to financial institutions or to Stockholders (excluding

                                      -10-
<PAGE>

current payroll obligations), if any, at the Closing (the "Closing Debt") will
not exceed $6,500,000. If the Closing Net Worth is determined to be less than
$10,330,247, or if the Closing Debt is determined to exceed $6,500,000, any such
deficiency and/or excess, whichever is applicable (and in each case subject to
adjustment pursuant to subparagraph 2(d) below), shall be paid by Stockholders
to Buyer by wire transfer of immediately available funds to the bank and account
designated by Buyer in writing to the Representative as follows: (A) if no
amounts or items shown on the Net Worth Statement (as hereinafter defined) have
been disputed as provided herein, within 5 business days after the expiration of
the 60 day review and audit period set forth in subparagraph 2(b)(ii), and (B)
if any amounts or items shown on the Net Worth Statement have been disputed,
within 5 business days following the resolution of all such disputed amounts or
items as provided herein. It is the intention of the Stockholders that any
payments due to the Buyer pursuant to the immediately preceding sentence shall
be paid by the Stockholders by way of payment by the Representative from the
funds held under the Stockholders' Escrow Agreement. As used in this Agreement,
the term "Net Worth" means the amount by which the sum of the book value of the
assets of the Corporation and the Subsidiaries on a consolidated basis exceeds
the sum of the book value of the liabilities of the Corporation and the
Subsidiaries on a consolidated basis, all as recognized, calculated and
determined in accordance with GAAP consistently applied with prior periods.

               (ii) Within 30 days following the Closing  Date (as hereinafter
defined), the Representative shall prepare and deliver to the Buyer a balance
sheet setting forth the Closing Net Worth and the Closing Debt (the "Net Worth
Statement"), which Net Worth Statement shall set forth in reasonable detail the
determination and calculation of the Closing Net Worth and the Closing

                                      -11-
<PAGE>

Debt. If and to the extent not within the control of the Representative, then
for purposes of preparing the Net Worth Statement, Buyer shall make reasonably
available (and shall cause the Corporation and its Subsidiaries to make
reasonably available) to the Representative (and the Representative's
accountants, attorneys, agents, and representatives) during normal business
hours, the books and records (including any accountants work papers) of the
Corporation and its Subsidiaries to the same extent, and subject to the same
conditions, as provided in Subparagraph 2(a)(iii)(H) with respect to the
preparation of the P&L Statement. For a period of 60 days after receipt by the
Buyer of the Net Worth Statement, the Buyer shall have the right to review and
audit such Net Worth Statement. For purposes of reviewing or auditing such Net
Worth Statement, if and to the extent not within the control of the Buyer, the
Representative shall make available to the Buyer (and the Buyer's accountants,
attorneys, agents and representatives) during normal business hours the books
and records (including any work papers used by the Representative to prepare the
Net Worth Statement) of the Corporation and its Subsidiaries, upon reasonable
advance notice to the Representative, and shall otherwise cooperate in good
faith with the Buyer's review or audit of said Net Worth Statement; provided,
however, that the Buyer (if and to the extent not within the control of the
Buyer) shall schedule such access through an authorized representative of
Representative and in such a way as to avoid material disruption of the normal
business operations of the Corporation. Unless the Representative shall receive
notice from the Buyer within such 60 day period to the effect that the Buyer
disputes one or more amounts or items shown on the Net Worth Statement, the Net
Worth Statement (including the determinations and calculations of the Closing
Net Worth and the Closing Debt set forth in the Net Worth Statement) shall be
final, conclusive and binding on all parties hereto. Any such notice from the
Buyer to the Representative disputing one or more amounts or

                                      -12-
<PAGE>

items on the Net Worth Statement as aforesaid shall specify in reasonable detail
the nature and amount of said dispute or disputes.

               (iii)  If the Representative receives notice from the Buyer
within the aforementioned 60 day period that the Buyer disputes one or more
amounts or items shown on the Net Worth Statement, then Buyer and the
Representative shall promptly thereafter meet in good faith to attempt to
resolve any and all such disputed amounts or items.  If and to the extent the
Buyer and the Representative resolve any such disputed amount or item, then (x)
such resolution shall be set forth in a writing signed by the Buyer and the
Representative, and (y) if such resolution would require the Stockholders to
make a payment to the Buyer pursuant to subparagraph 2(b)(i), then the
Stockholders shall make such payment as provided in subparagraph 2(b)(i).  If
and to the extent Buyer and the Representative are unable to agree upon a
resolution of any disputed amount or item within 15 days after receipt by the
Representative of Buyer's notice regarding the existence of such disputed amount
or item, then such disputed amount or item shall be resolved by an independent
nationally recognized accounting firm, selected by mutual written agreement of
Buyer and the Representative, which is not then providing, and has not provided
at  any time during the period commencing one-year prior to the Closing Date
through the date of their determination pursuant to this subparagraph 2(b)(iii),
services to any of (i) Buyer or any of its Affiliates or (ii) Corporation or any
of its Affiliates ("Independent Accountants").  Upon their appointment, the
Independent Accountants shall certify to the Buyer and the Representative in
writing that they satisfy the foregoing qualifications.  If Buyer and the
Representative are unable to agree on mutually acceptable Independent
Accountants during the aforesaid 15 day period, then such Independent
Accountants shall be selected, within 10 days thereafter, by mutual agreement of
Buyer's independent public

                                      -13-

accountant and Representative's independent public accountant (which the
Representative anticipates will be Aronson, Fetridge & Weigle), joint notice of
which appointment shall be provided by such accountants to the Buyer and the
Representative. Unless otherwise agreed by the Buyer and the Representative, the
Buyer and the Representative shall each have the opportunity to make a written
submission to the Independent Accountants with respect to the disputed amounts
or items setting forth their positions and analysis, along with reasonable
supporting documentation (which may include this Agreement, the Net Worth
Statement and the Buyer's notice disputing the same, and the P&L Statement and
the Buyer's notice disputing the same, as the case may be, and any agreements of
the Buyer and the Representative resolving any disputes with respect thereto),
provided that such submissions are made within 10 business days after either (x)
the date on which the Buyer and the Representative mutually agree to such
Independent Accountant, or (y) dates on which the Buyer and the Representative,
respectively, receive the aforesaid joint notice of the appointment of the
Independent Accountant, as the case may be. Unless otherwise agreed in writing
by the Buyer, the Representative and the Independent Accountant, the Independent
Accountants shall resolve the disputes based solely on the written submission or
submissions received by the Independent Accountants, and there shall be no oral
presentations. Buyer and the Representative shall instruct the Independent

and/or the amounts or remaining amounts, if any, payable by the Stockholders
under subparagraph 2(b)(i), as the case may be) simultaneously to the Buyer and
the Representative. The resolution of such disputed amounts and items by the
Independent Accountants

                                      -14-
<PAGE>

shall be final, conclusive and binding upon all parties. The fees and expenses
of the Independent Accountants shall be borne equally by Buyer, on one hand, and
the Stockholders, on the other hand. It is the intention of the Stockholders
that any fees and expenses due from the Stockholders to the Independent
Accountants pursuant to the immediately preceding sentence shall be paid by the
Stockholders by way of payment by the Representative from the funds held under
the Stockholders' Escrow Agreement.

     (c)  Modifications of GAAP after the date of this Agreement will be
disregarded for purposes of this paragraph 2.

     (d)  If the Stockholders do not own 100% of the Shares, then the Purchase
Price (and each item thereof) shall be proportionately reduced by the percentage
of the Shares not owned by the Stockholders so that the Buyer shall pay the
Purchase Price as follows: (i) the amount otherwise payable by the Buyer under
subparagraph 2(a)(i) if the Stockholders owned 100% of the Shares shall be
multiplied by the percentage of the Shares owned by the Stockholders, (ii) the
amount otherwise payable by the Buyer under subparagraph 2(a)(ii) if the
Stockholders owned 100% of the Shares shall be multiplied by the percentage of
the Shares owned by the Stockholders, and (iii) the amount otherwise payable by
the Buyer under subparagraph 2(a)(iii) if the Stockholders owned 100% of the
Shares shall be multiplied by the percentage of the Shares owned by the
Stockholders.  Likewise, if the Stockholders do not own 100% of the Shares, then
the amounts (if any) payable by the Stockholders to the Buyer pursuant to
subparagraph 2(b) (and each item thereof) shall be proportionately reduced by
the percentage of the Shares not owned by the Stockholders so that the
Stockholders shall pay (x) any amount by which the Closing Net Worth is less
than $10,330,247 multiplied by the percentage of the Shares owned by the
Stockholders, and (y) any amount by which

                                      -15-
<PAGE>

the Closing Debt is in excess of $6,500,000 multiplied by the percentage of the
Shares owned by the Stockholders. For purposes of this subparagraph 2(d), the
percentages of the Shares owned by the Stockholders shall be as set forth
opposite their respective names on Schedule 4(a).
                                   -------------

     (e)  (i)  "Stand Alone" shall mean without cost allocations from the Buyer
and/or its Affiliates to the Corporation and/or is Subsidiaries, other than the
G&A Allocations.  Services and goods which the Corporation and/or its
Subsidiaries usually require, and which are performed or provided for the
Corporation and/or its Subsidiaries at a cost equal to or less than the cost of
equivalent services or goods in the marketplace or at the written request or
approval of the Representative, shall be charged to the Corporation or its
Subsidiaries, as the case may be, as any other charge or expense for such
service or good.  The Buyer and its Affiliates shall not allocate any of their
attorneys fees and expenses, accountants fees and expenses, or any other fees,
expenses or costs, arising out of or relating to this Agreement and the
transactions contemplated hereby to the Corporation and/or its Subsidiaries.

          (ii) In the event that from the consummation of Closing through April
30, 2001 (i.e., during the subparagraph 2(a)(iii) measurement periods), (A) the
Buyer sells, assigns, conveys, transfers or exchanges any shares of capital
stock of the Corporation and/or its Subsidiaries (excluding the Former Foreign
Subsidiaries) and immediately thereafter the Buyer ceases to own, directly or
indirectly, at least substantially all of the outstanding capital stock of the
Corporation and the Subsidiaries (excluding the Former Foreign Subsidiaries),
(B) there shall be a merger or consolidation of the Corporation and/or its
Subsidiaries (subject to subparagraph 2(e)(iii)) other than a merger or
consolidation of the Corporation and its Subsidiaries, (C) the Corporation
and/or its Subsidiaries sells, leases, licenses or otherwise transfers, assigns
or conveys its assets other than in

                                      -16-
<PAGE>

the ordinary course of business, or (D) the Corporation dissolves or liquidates
and, as a result of the taking of any of the actions set forth in subparagraphs
2(e)(ii)(A)-(D), it will become impossible to measure the Revenue and EBITDA of
the Corporation necessary to Calculate the Contingent Payments in subparagraph
2(a)(iii) above and therefore, such payments shall become due and payable at the
times, and in the manner, set forth in subparagraph 2(a)(iii) above as if such
Revenue and EBITDA Targets were achieved in full.

          (iii)  If the Stockholders own less than 100% of the Shares, the Buyer
may cause the merger of the Corporation with a newly-formed wholly-owned
corporate shell subsidiary of Buyer (i.e., a corporation with no assets or
liabilities) (the "New Subsidiary"), with either the New Subsidiary or the
Corporation being the survivor. Effective upon consummation of such a merger, if
the New Subsidiary is the survivor, references to the Corporation in this
Paragraph 2 shall include the New Subsidiary where appropriate (e.g., to reflect
that the New Subsidiary is the successor to the Corporation for purposes of
measuring whether payments are due under subparagraph 2(a)(iii)).

     (j)  Accounts Receivable. Each of the accounts receivable of the
          -------------------
Corporation and the Subsidiaries (including billed accounts, retention and
unbilled recoverable amounts under contracts with governmental units)
outstanding as of the Closing Date constitutes on such date a valid claim in the
full amount thereof against the debtor charged therewith on the books of the
Corporation or the Subsidiaries (consistent with the direct write-off method of
accounting utilized by the Corporation and the Subsidiaries) and was acquired in
the ordinary course of the Corporation's or the Subsidiaries' business.  Such
accounts receivable will be fully collected to the extent of the face value
thereof.  The Stockholders hereby agree to pay Buyer upon Buyer's written demand
and without regard to any limitations contained in Paragraph 16(e), an amount
equal to the difference between (i) the aggregate face value of all  accounts
receivable (excluding retention

                                      -30-
<PAGE>

amounts under contracts with governmental units) not collected in full within 12
months of the Closing Date (the "Uncollected Receivables"), and (ii) the sum of
the reserve for doubtful accounts reflected on the Net Worth Statement and the
amount, if any, by which the Closing Net Worth exceeds $10,330,247 (the
"Receivable Deficiency"). If any Uncollected Receivables are subsequently
collected by Buyer, the Corporation and/or the Subsidiary within three years
after the Closing Date, any such amounts so collected, up to the amount of the
Receivable Deficiency, shall be paid by the Buyer within 60 days of such
collection to the Representative to be allocated (subject to the terms and
condition of the Stockholders' Escrow Agreement) among the Stockholders in
accordance with the percentages set forth opposite each Stockholders' name on
Schedule 4(a). All demands for payment of a Receivable Deficiency by Buyer
-------------
pursuant to this Section 5(j) shall be made within 90 days after the first
anniversary of the Closing Date, and such demands shall identify the Uncollected
Receivables and shall set forth in reasonable detail the Buyer's calculation of
the Receivable Deficiency. If and to the extent not within the control of the
Representative, then for purposes of reviewing said demand the Buyer shall make
reasonably available (and shall cause the Corporation and its subsidiaries to
make reasonably available) to the Representative (and the Representative's
accountants, attorneys, agents and representatives) during normal business
hours, the books and records (including any accountants work papers) of the
Corporation and its Subsidiaries to the same extent, and subject to the same
conditions, as provided in Subsection 2(a)(iii)(H) with respect to the
preparation of the P&L Statement. Unless the Buyer receives notice from the
Representative within 15 days of the Representative's receipt of the demand for
the Receivable Deficiency to the effect that the Representative disputes one or
more amounts or items set forth in said demand, the demand shall be final,
conclusive and binding on all parties hereto, and

                                      -31-
<PAGE>

the Stockholders shall pay the amount of said Receivable Deficiency to the Buyer
within said 15 day period. If the Buyer receives notice from the Representative
within 15 days of the Representative's receipt of the demand for the Receivable
Deficiency to the effect that the Representative disputes one or more amounts or
items set forth in said demand, such dispute shall be settled pursuant to the
procedures set forth in Subsection 2(b)(iii) relating to the settlement of
disputes regarding the Net Worth Statement, and the amount of the Receivable
Deficiency (if any) so determined to be payable to the Buyer shall be paid by
the Stockholders within 5 days of such determination. No account debtor has any
valid set-off, deduction or defense with respect thereto and no account debtor
has asserted any such set-off, deduction or defense. Over the past 6 years,
write-offs of accounts receivable through the direct write-off method of
accounting utilized by the Corporation have not been material.

          (k) Insurance.  The Corporation and the Subsidiaries maintain
              ---------
insurance policies bearing the numbers for the terms, with the companies, in the
amounts, having the named insureds, providing the general coverage, and with the

                      -------------
effect, neither the Corporation nor any Subsidiary is in default of any
provision thereof and all premiums due (without regard to any grace period) with
respect to such policies have been paid.   Neither the Corporation nor any
Subsidiary has been refused any insurance for which it has applied and has not
received notice from any issuer of any policy issued to it of the insurer's
intention to cancel or refusal to renew any such policy issued by such insurer.
True, correct and complete copies of all such policies have been delivered to
Buyer.

          (1) Liabilities. At the Closing, neither the Corporation nor any
              -----------
Subsidiary shall have any liabilities, whether fixed, contingent, or otherwise,
except as and to the extent reflected on

and will not, with or without the giving of notice, the lapse of time, or both,

meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974,

individually as "Plan" and collectively as "Plans").  For purposes of this
Agreement, "ERISA Affiliate" means all persons and entities which are treated as
            ---------------
being under common control with the Corporation, as the case may be, the

document and trust agreement (including any

change in the funding status or financial condition of such Plan.

               (iii)  Each Plan is and has been maintained in compliance in all

incurred a minimum funding deficiency within the meaning of Section 412 of the
Code whether or not waived. The assets of the Corporation, the Subsidiaries, and

value of all benefit liabilities (as that term is defined in Section 4001(a)(16)
of ERISA) of a plan subject to Title IV of ERISA exceeds the fair market value
of all assets of such plan, all determined using the actuarial assumptions that
would be used by the PBGC in the event of a termination of the plan on such
determination date.

          (vi)   Except as reflected on Schedule 5(o)(vi), there are no pending
                                        -----------------

Affiliate with respect to any 412 Plan, or (C) any fiduciary with respect to any
Plan for which the Corporation, any Subsidiary, or any ERISA Affiliate may be
directly or indirectly be liable, through indemnification obligations or

and any Subsidiary (taking into account all extensions of time within which to
file to which they are entitled or which they may have been granted). All such
Returns are correct and complete. Except as set forth on Schedule 5(v)(ii)(A),
                                                         --------------------
neither the Corporation nor any Subsidiary is the current beneficiary of any
extension of time within which to file any Return. No claim has been made by a
taxing authority in a jurisdiction where the Corporation and any Subsidiary does
not file Returns that any of them is or may be subject to or liable for any Tax
imposed by that jurisdiction.

                   (B)   All Taxes for which each of the Corporation and any
Subsidiary is liable and that are due on or before the date hereof or the
Closing Date (whether or not shown to be due on any Return) have been paid when
due in a timely fashion (taking into account all extensions of time within which
to pay to which they are entitled or which they may have been granted). There
are no liens on any assets of the Corporation or any Subsidiary that arose in
connection with any failure (or alleged failure) to pay any Tax other than liens
for Taxes not yet due and payable or for Taxes that the Corporation or any
Subsidiary or the Stockholders are contesting in good faith through appropriate
proceedings as set forth on Schedule 5(v)(ii)(B).

employee, independent contractor, creditor, stockholder, member, partner or
other third party.

                   (D)   No taxing authority has asserted, or threatened to
assert, any adjustment, deficiency or assessment for any Taxes against the

Subsidiary), and no basis exists for any such adjustment, deficiency or
assessment which would result in additional Taxes owed by the Corporation or any
Subsidiary (with respect to the Corporation or any Subsidiary) for any period
for which Returns have been filed since December 31, 1992. Schedule 5(v)(ii)(D)
                                                           --------------------

the Subsidiaries) have waived any statute of limitations in respect of Taxes or
agreed to any extension of time with respect

                                      -54-

                                                --------------------
the Corporation nor any Subsidiary has any income or gain that may be reportable

Buyer makes the following representations, warranties and agreements to and with
Stockholders, which representations, warranties and agreements shall be true and
correct as of the date of this Agreement and as of the Closing Date:

          (a)  Corporate Status and Authority.  Buyer is a corporation duly
               ------------------------------
organized, validly existing and in good standing under the laws of the State of
Delaware, and has the corporate power and authority to execute, deliver and
perform this Agreement and the documents contemplated hereby, including to

performance of this Agreement by Buyer have been duly authorized by all
necessary corporate action on the part of Buyer, and this Agreement and the
documents contemplated hereby to be executed and delivered by the Buyer have
been duly executed and delivered by Buyer, or will be duly executed and

<PAGE>

          (b)  Agreement Not in Breach of Other Instruments Affecting Buyer. The
               ------------------------------------------------------------
execution and delivery of this Agreement, the consummation of the transactions
provided for herein, and the fulfillment of the terms hereof by Buyer do not and
will not, with or without the giving of notice, the lapse of time, or both,
result in the breach of any of the terms and provisions of, or constitute a
default under, or conflict with, or cause any acceleration of any obligation of
Buyer under, any agreement, indenture or other instrument by which Buyer is
bound, Buyer's Certificate of Incorporation or Bylaws, any judgment, decree,
order, or award of any court, governmental body, or arbitrator, or any
applicable law, rule, or regulation.

          (c)  No Broker or Finder.  The Buyer has not taken any action, or
               -------------------
incurred any obligation, contingent or otherwise, which would give rise to a
valid claim against the Stockholders and/or the Corporation by a broker, finder,
agent or other intermediary for introducing the parties in connection with, or
otherwise procuring, this Agreement or the transaction(s) contemplated hereby.
With regard to the Stockholders' broker, see Paragraph 23.

account, as a principal, for investment purposes and not with a view to or for
the sale or other disposition thereof. Buyer agrees that it will not sell,
assign, distribute or otherwise dispose of the Shares in violation of the
Securities Act or any applicable State Act.

          (e)  Access and Investigation.  Buyer acknowledges that the
               ------------------------
Stockholders have afforded the Buyer and its attorneys, accountants,
representatives and agents with full and free access to the Corporation's and
Subsidiaries' premises, accounts, books and records, personnel, properties,

          (v)  By Buyer, if the Corporation or the Subsidiary (Quantum Research

of no further force or effect, all of the rights and obligations of the parties
under this Agreement (but not under the Confidentiality Agreement); provided,
however, that no such termination shall be deemed to relieve any defaulting or
breaching party from any liability to the other parties hereto, or to otherwise
eliminate, reduce or affect in any way any cause of action, action or claim,
whether at law, in equity or otherwise, which any non-defaulting and non-
breaching party may or shall have against the defaulting or breaching party
under or arising out of this Agreement, or to be deemed an election of remedies
which precludes, waives or otherwise affects any of the foregoing.  Upon any

          (c)  Procedures for Establishment of Deficiencies.
               --------------------------------------------

               (i)    In the event that any claim shall be asserted against
Buyer, the Corporation or any Subsidiary which, if sustained, would result in a
Deficiency, Buyer, within a reasonable time after learning of such claim, shall
notify the Representative in writing of such claim, which notice shall set forth
in reasonable detail the basis for and the Buyer's good faith determination of
the amount of such claim and shall extend to the Stockholders (which may act
through the

                                      -77-
<PAGE>

Representative) a reasonable opportunity to defend against such claim through
the Buyer, the Corporation or the Subsidiary, as the case may be, with legal
counsel reasonably acceptable to Buyer and utilizing any insurance coverage
which may be available with respect to such claim and/or the costs and expenses
of the defense thereof; provided that the Stockholders (which may act through
the Representative) proceed in good faith, expeditiously and diligently. The
costs and expenses of such defense on behalf of the Stockholders (which may act
through the Representative), if and to the extent not covered by insurance, as
well as any increase in insurance premiums attributed to such coverage, shall be
deemed a Deficiency. Buyer shall, at its option and expense, have the right to
participate in any defense undertaken by the Stockholders (which may act through
the Representative) with legal counsel of its own selection. If the Stockholders
(which may act through the Representative), in the reasonable judgment of Buyer
after written notice to the Representative and opportunity to cure, have failed
to prosecute such defense through the Buyer, the Corporation or the Subsidiary,
as the case may be, in good faith in an expeditious and diligent manner, Buyer
shall have the right, in good faith, to defend and/or settle such claim on
behalf of the Stockholders at the Stockholders' expense. No settlement or
compromise of any claim which may result in a Deficiency may be made by the
Stockholders (which may act through the Representative) without the prior
written consent of Buyer unless the proposed settlement is solely a monetary
settlement and prior to such settlement or compromise the Stockholders (which
may act through the Representative) acknowledge in writing their obligation to
pay in full the amount of the settlement and all associated expenses (subject to
the limitations set forth in this Paragraph 16) and Buyer is furnished with a
full release from the claimant in form and substance reasonably satisfactory to
Buyer. In connection with the defense against the claim, the Buyer shall make
reasonably available (and shall cause the

                                      -78-
<PAGE>

Corporation and its Subsidiaries to make reasonably available) to the
Stockholders (which may act through the Representative) and their accountants,
attorneys, agents, and representatives during normal business hours the books
and records (including any accountants work papers), contracts, agreements,
documents, instruments and other information relating to the claim, upon
reasonable advance notice to the Buyer, and shall otherwise cooperate in good
faith with the Stockholders (which may act through the Representative) with
respect to the defense against the claim, including in connection with
compliance with any subpoena, request for documents, or similar request for
discovery; provided, however, that the Stockholders (which may act through the
Representative) shall schedule such access or requests through an authorized
representative of Buyer and in such a way as to avoid material disruption of the
normal business operations of the Corporation.

          (ii)    In the event that Buyer asserts the existence of any
Deficiency, Buyer shall give written notice to the Representative of the nature
and amount of the Deficiency asserted. If the Representative, within a period of
15 business days after receipt of such notice from Buyer, shall not give written
notice to Buyer announcing their intention to contest such assertion of Buyer
(such notice by the Representative being hereinafter called the "Contest
Notice"), such assertion of Buyer shall be deemed accepted and the amount of the
Deficiency shall be deemed established. In the event, however, that a Contest
Notice is given to Buyer within said fifteen-business day period, then the
contested assertion of a Deficiency shall be settled by arbitration to be held
in Wilmington, Delaware by a single arbitrator in accordance with the commercial
arbitration rules of the American Arbitration Association then obtaining. The
arbitrator shall be required to be an attorney or a certified public accountant.
The arbitrator shall be neutral, shall be required to disclose any actual or
apparent conflicts of interest in writing to both the Buyer and the Stockholders
(which may act

                                      -79-
<PAGE>

through the Representative), and shall comply with the Code of Ethics of the
American Arbitration Association. The parties shall stipulate that any such
arbitration must be concluded within 120 days of the date submitted to the
American Arbitration Association, or such other period as to which the Buyer and
the Stockholders (which may act through the Representative) may agree in
writing. The Buyer or the Stockholders (which may act through the
Representative) may, at their expense (unless otherwise determined by the
arbitrator in the arbitrator's decision), request that a stenographic record be
kept of the arbitration proceedings. The Buyer and the Stockholders (which may
act through the Representative) shall be afforded a reasonable opportunity to
request documents, information and materials from each other, as determined and
enforced by the arbitrator. The arbitration shall be governed by the laws of
Delaware. The arbitrator may not grant punitive damages. The parties shall
instruct the arbitrator to deliver his or her determination in writing to the
Stockholders and Buyer within 30 days from the date of closing of the
arbitration hearings, and shall be final, binding and conclusive upon all of the
parties hereto, and the amount of the Deficiency, if any, determined to exist by
the arbitrator shall be deemed established. Unless otherwise determined by the
arbitrator, the costs of the arbitrator and the arbitration proceeding shall be
borne by the party losing the arbitration, as shall be determined by the
arbitrator and set forth in the arbitrator's decision.

               (iii)   Buyer and the Stockholders (which may act through the
Representative) may agree in writing, at any time, as to the existence and
amount of a Deficiency, and, upon the execution of such agreement, such
Deficiency shall be deemed established.

          (d)  Payment of Deficiencies.  Subject to subparagraph 16(e), any
               -----------------------
Deficiency shall first be payable out of the Escrow (if and to the extent then
held by the Escrow Agent under the Escrow Agreement) and second out of the
earned and unpaid portion of the Contingent Payments.

                                      -80-
<PAGE>

If at the time a Contingent Payment is due to be made to the Stockholders there
are not claims (subject to the limitations in subparagraph 16(e) below) which
exceed the Escrow (if and to the extent then held by the Escrow Agent under the
Escrow Agreement), such Contingent Payment shall be made; further, if at the
time a Contingent Payment is due to be made there are claims (subject to the
limitations in subparagraph 16(e) below) which exceed the amount then held in
Escrow, only the portion of the Contingent Payment required to cover such claims
(which may constitute the entire Contingent Payment) shall be held pending
resolution of such claims, and the balance of the Contingent Payment then due,
if any, shall be paid to the Stockholders.

          (e)  Limitation.  With the exception of (i) any Deficiencies resulting
               ----------
from any misrepresentation, breach of representation or warranty, or any non-
fulfillment of any representation, warranty, covenant or agreement on the part
of the Stockholders contained Paragraph 4(a) herein, (ii) any Deficiencies
resulting from a Knowing Misrepresentation on the part of the Stockholders, or
on the part of Quirk and/or Errecart, (iii) any Deficiencies resulting from a
breach of the representation contained in subparagraph 5(y), or (iv) any
Deficiencies set forth in subparagraph 16(b)(vii) (and 16(b)(x) as it relates to
16(b)(vii)), with respect to which there shall be no limitations, (x) there
shall be no liability for any Deficiency unless and until the aggregate of all
Deficiencies exceeds $400,000 (the "Basket"), in which event there shall be
liability for Deficiencies only to the extent that such Deficiencies exceed
$400,000, and (y) Stockholders shall not be liable or otherwise responsible for
the payment of Deficiencies to the extent such Deficiencies exceeds an amount
equal to the sum of the Escrow and the earned and unpaid portion of the
Contingent Payments. Notwithstanding the foregoing, in no event shall a
Deficiency set forth in subparagraph 16(b)(viii) (and 16(b)(x) as it relates to
16(b)(viii)) be subject to a Basket greater than $100,000.  The rights of

                                      -81-
<PAGE>

indemnification provided for in this Paragraph 16 shall be the sole and
exclusive remedy of the Buyer Indemnified Parties with respect to any
Deficiencies and any other claims by any of the Buyer Indemnified Parties
against any or all of the Stockholders arising out of or relating to this
Agreement and/or the transactions contemplated by this Agreement.

     17.  Indemnification of Stockholders.
          -------------------------------

     (a)  Basic Provision. The Buyer hereby indemnifies and agrees to hold
          ---------------
harmless the Stockholders, and their respective successors, assigns, trustees,
representatives and agents (collectively, the "Stockholder Indemnified Parties")
(each of whom shall be a third party beneficiary hereof) from, against and in
respect of the amount of any and all Buyer Deficiencies (as hereinafter
defined).

          (b)  Definition of "Buyer Deficiencies". As used in this Paragraph 17,
               ----------------------------------
"Buyer Deficiencies" means any and all loss or damage incurred by the
Stockholder Indemnified Parties resulting from:

               (i)    any misrepresentation, breach of any representation or
warranty, or any non-fulfillment of any representation, warranty, covenant or
agreement on the part of the Buyer contained in this Agreement;

               (ii)   any misrepresentation contained in any statement, report,
certificate or other document or instrument delivered to the Representative or
the Stockholders pursuant to this Agreement; and

               (iii)  any and all actions, suits, proceedings, demands,
assessments, penalties, liabilities, judgments, reasonable attorneys' fees,
costs, expenses and interest incident to any of the foregoing.

          (c)  Procedures for Establishment of Buyer Deficiencies.
               --------------------------------------------------

               (i)    In the event that any claim shall be asserted against the
Stockholders and/or the Representative which, if sustained, would result in a
Buyer Deficiency, the Stockholders (which may act through the Representative),
within a reasonable time after learning of such claim, shall notify the Buyer in
writing of such claim, which notice shall set forth in reasonable detail the
basis for and the Stockholders and/or Representative's good faith determination
of the amount of such claim and shall extend to the Buyer a reasonable
opportunity to defend against such claim, at the Buyer's sole expense and
through legal counsel reasonably satisfactory to the Stockholders (which may act
through the Representative), provided that the Buyer proceeds in good faith,
expeditiously and diligently. The Stockholders (which may act through the
Representative) shall, at their option and expense, have the right to
participate in any defense undertaken by the Buyer with legal counsel of its own
selection. If the Buyer, in the reasonable judgment of the Stockholders (which
may act through the Representative) after written notice to the Buyer and
opportunity to cure, have failed to prosecute such defense in good faith in an
expeditious and diligent manner, the Stockholders (which may act through the
Representative) shall have the right, in good faith, to defend and/or settle
such claim on behalf of the Buyer at the Buyer's expense. No settlement or
compromise of any claim which may result in a Buyer Deficiency may be made by
the Buyer without the prior written consent of the Stockholders (which may act
through the Representative) unless the proposed settlement is solely a monetary
settlement and prior to such settlement or compromise the Buyer acknowledges in
writing its obligation to pay in full the amount of the settlement and all
associated expenses and the Stockholders (which may act through the
Representative) are furnished with a full release from the claimant in form and
substance reasonably

                                      -83-
<PAGE>

satisfactory to the Stockholders (which may act through the Representative). In
connection with the defense against the claim, the Stockholders (which may act
through the Representative) shall make reasonably available to the Buyer and its
accountants, attorneys, agents, and representatives during normal business hours
such books and records (including any accountants work papers), contracts,
agreements, documents, instruments and other information relating to the claim
as are in the possession or control of the Stockholders (which may act through
the Representative), upon reasonable advance notice to the Stockholders (which
may act through the Representative), and shall otherwise cooperate in good faith
with the Buyer with respect to the defense against the claim, including in
connection with compliance with any subpoena, request for documents, or similar
request for discovery; provided, however, that the Buyer shall schedule such
access or requests through an authorized representative of the Stockholders
(which may act through the Representative) and in such a way as to avoid
material disruption of the normal business operations of the Corporation.

               (ii)   In the event that the Stockholders (which may act through
the Representative) assert the existence of any Buyer Deficiency, the
Stockholders (which may act through the Representative) shall give written
notice to the Buyer of the nature and amount of the Buyer Deficiency asserted.
If the Buyer, within a period of 15 business days after receipt of such notice
from the Stockholders (which may act through the Representative), shall not give
written notice to the Stockholders (which may act through the Representative)
announcing its intention to contest such assertion of the Stockholders (which
may act through the Representative) (such notice by the Buyer being hereinafter
called the "Buyer Contest Notice"), such assertion of the Stockholders (which
may act through the Representative) shall be deemed accepted and the amount of
the Buyer

                                      -84-
<PAGE>

Deficiency shall be deemed established. In the event, however, that a Buyer
Contest Notice is given to the Stockholders (which may act through the
Representative) within said fifteen-business day period, then the contested
assertion of a Buyer Deficiency shall be settled by arbitration under the
provisions as set forth in subparagraph 16(c)(ii).

               (iii)  Buyer and the Stockholders (which may act through the
Representative) may agree in writing, at any time, as to the existence and
amount of a Buyer Deficiency, and, upon the execution of such agreement, such
Buyer Deficiency shall be deemed established.

          (d)  Payment of Buyer Deficiencies. Any Buyer Deficiency determined to
               -----------------------------
be due and payable by Buyer pursuant to subparagraph 17(c) shall be paid within
5 business days of such determination.

     18.  Covenants Relating to Employee Benefits.
          ---------------------------------------

          (a)  Subject to subparagraph 18(b), Buyer agrees to maintain, to the
extent possible, substantially the same employee benefits as are enjoyed by the
employees of the Corporation and the Subsidiaries on the date of this Agreement.
Subject to subparagraph 18(b), such employee benefits shall be maintained until
the second anniversary of the Closing Date; provided, however, that Buyer shall
be permitted to make such modifications in such employee benefits on or after
the first anniversary of the Closing Date to the extent Buyer concludes that
such changes are required in order to maintain such employee benefit programs in
compliance with applicable provisions of the Code or of ERISA, including, but
not limited to the nondiscrimination rules applicable to pension and/or welfare
plans, or if the Buyer determines there are other compelling reasons to modify
such arrangements.  In the event the Buyer determines that a material
modification

                                      -85-
<PAGE>

of the employee benefits arrangements of the Corporation or the Subsidiaries is
appropriate before the second anniversary of the Closing Date, the Buyer will
take reasonable efforts to implement a modification which is mutual acceptable
to Buyer and the Representative and consistent with subparagraph 2(e).

          (b)  The Buyer agrees not to take any action, or omit to take any
action, which would cause the Corporation to breach or otherwise violate Section
9.1(b) of that certain Stock Purchase Agreement dated as of June 27, 1997, by
and among the Corporation, George J. Nozicka, David G. Abraham, and the Quantum
Research Corporation Employee Stock Ownership Plan and the related Trust, a
true, correct and complete copy of which has been delivered to Buyer.

          (c)  The employees of the Corporation and its Subsidiaries shall not
be deemed third party beneficiaries of this Paragraph 18.

     19.  Tax Covenants Relating to Corporation.
          -------------------------------------

          (a)  The following provisions shall govern the allocation of
responsibility as between Buyer and Stockholders for certain Tax matters
following the Closing Date:

               (i)    Buyer and the Stockholders (which may act through the
Representative) shall cause the tax year of the Corporation and the Subsidiaries
for Federal and state income tax purposes to end on the Closing Date to the
extent permitted by law.  The Corporation shall timely prepare or cause to be
prepared and file or cause to be filed all Returns for the Corporation and each
of the Subsidiaries for all Tax periods ending on or prior to the Closing Date
which are to be filed after the Closing Date, and shall pay the Taxes due with
respect to such Returns. Copies of all such Returns shall be made available to
the Buyer at least 10 days prior to the date on which they are to be filed.
During said 10 day period the Buyer may provide the Corporation

                                      -86-
<PAGE>

with such comments or proposed changes as it deems appropriate. If any such
Return (as filed) indicates that the Corporation or any Subsidiary has incurred
any liability for Tax in excess of the amount of such Taxes which are included
in the reserve for Tax liability (rather than any reserve for deferred Taxes
established to reflect timing differences between book and Tax income) on the
Net Worth Statement (as determined to be final, conclusive and binding on all
parties pursuant to subparagraph 2(b) hereof), the Stockholders shall pay such
excess to Buyer if and to the extent provided in Paragraph 16.

               (ii)    If and to the extent not filed prior to the Closing Date,
Buyer at its expense shall timely prepare or cause to be prepared and file or
cause to be filed all Returns for the Corporation and each Subsidiary for Tax
periods which begin before the Closing Date and end after the Closing Date and
shall pay the Taxes due with respect to such Returns. Copies of all such Returns
shall be made available to the Representative at least 10 days prior to the date
on which they are to be filed. During said 10 day period the Representative may
provide the Buyer with such comments or proposed changes as it deems
appropriate. If and to the extent provided in Paragraph 16, Stockholders shall
pay to Buyer the excess of (x) a pro rated amount (calculated as described in
subparagraph 13(a)(ii)(A) or (B), as applicable) of the Taxes of each of the
Corporation and the Subsidiaries for any such period based on said Returns (as
filed) over (y) the amount of the Taxes paid by each of the Corporation and the
Subsidiaries on or prior to the Closing Date with respect to such period and the
amount of such Taxes which are included in the reserve for Tax liability (rather
than any reserve for Tax liability to reflect timing differences between book
and Tax items) on the Net Worth Statement (as determined to be final, conclusive
and binding on all parties pursuant to

                                      -87-
<PAGE>

subparagraph 2(b) hereof). Such payment by Stockholders to the Buyer shall be
made if and to the extent provided in Paragraph 16.

                       (A)  In the case of all Taxes imposed upon or measured by
property or capital, the pro rated amount shall be based upon the number of days
in the period up to and including the Closing Date divided by the total number
of days in the Tax period.

                       (B)  In the case of all Taxes other than those imposed
upon or measured by property or capital, including but not limited to net
income, gross receipts taxes, sales and use taxes, and payroll taxes, the pro
rated amount shall be based upon the transactions occurring on or before the
Closing Date.

          (b)  All tax sharing agreements or similar agreements with respect to
or involving the Corporation shall be terminated as of the Closing Date and,
after the Closing Date, the Corporation shall not be bound thereby or have any
liability thereunder.

          (c)  All transfer (including real estate), documentary, sales, use,
stamp, registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement shall be paid by
Stockholders when due, and Stockholders (or the Representative) shall, at their
own expense, file all necessary Returns and other documentation with respect to
all such transfer, documentary, sales, use, stamp, registration and other Taxes
and fees, and, if required by applicable law, Buyer will, and will cause its
Affiliates to, join in the execution of any such Returns and other
documentation.

          (d)  Buyer and the Stockholders (which may be through the
Representative) shall cooperate fully (and cause the Corporation and the
Subsidiaries to cooperate fully), as and to the extent reasonably requested by
the other party, in connection with the preparation, execution and

                                      -88-
<PAGE>

filing of Returns pursuant to this Agreement and any audit, contest, litigation
or other proceeding with respect to Taxes. Such cooperation shall include
retention and (upon the other party's request) the provision of records and
information which are reasonably relevant to any such audit, litigation or other
proceeding and making themselves, in the case of the Stockholders, and
employees, in the case of the Buyer, available on a mutually convenient basis to
provide additional information and explanation of any material. Stockholders and
Buyer agree (i) to retain all books and records with respect to Tax matters
pertinent to the Corporation and the Subsidiaries relating to any Tax period
beginning before the Closing Date until the expiration of the stature of
limitations (and, to the extent notified by the Buyer or the Representative, as
the case may be, any extensions thereof) of the respective taxable periods
(unless such items were transferred pursuant to this Agreement), and to abide by
all record retention agreements entered into with any Tax authority, (ii) to
cause the Corporation and the Subsidiaries to retain all books and records with
respect to Tax matters pertinent to the Corporation and the Subsidiaries
relating to any Tax period beginning before the Closing Date until the
expiration of the statute of limitations (and, to the extent notified by the
Buyer or the Representative, as the case may be, any extensions thereof) of the
respective taxable periods, and to abide by all record retention agreements
entered into with any Tax authority, and (iii) to give Buyer and the
Stockholders (which may be through the Representative), as the case may be,
reasonable written notice prior to transferring, destroying or discarding any
such books and records and, if the Buyer so requests, Stockholders shall allow
the Buyer to take possession of such books and records to be held, made
available and disposed of subject to the provisions of this subparagraph 19(d).

                                      -89-
<PAGE>

          (e)  Buyer and the Stockholders (which may be through the
Representative) agree, upon request, to use their reasonable efforts to obtain
any certificate or other document from any governmental authority or any other
person as may be necessary to mitigate, reduce or eliminate any Tax that could
be imposed (including, but not limited to, with respect to the transactions
contemplated hereby).

          (f)  Buyer and Stockholders (which may be through the Representative)
agree, upon request, to provide the other party with all information that either
party may be required to report pursuant to Code Section 6043 and all
Regulations promulgated thereunder.

          (g)  Buyer shall promptly notify the Stockholders in writing of the
commencement of any claim, audit, examination, or other proposed change or
adjustment by any Tax authority concerning any Tax or other similar claim or
assessment for which the Stockholders may be responsible (a "Tax Claim");
provided, however, that failure to give such notice shall not relieve any party
from its obligation to indemnify with respect to any such Tax Claim except to
the extent of actual prejudice. The Representative, through the Corporation or
the Subsidiaries, as the case may be, affected by such Tax Claim, shall have the
right to employ counsel of its choice and to participate with Buyer, Corporation
and any Subsidiaries in resolving any dispute of Taxes with respect to Tax
periods beginning before the Closing Date through the appropriate administrative
offices and in the courts, and shall have primary responsibility for the conduct
of any such proceedings relating solely to periods ending on or before the
Closing Date. In connection with the defense against any Tax Claim relating
solely to periods ending on or before the Closing Date, the costs and expenses
of such defense on behalf of the Stockholders (which may act through the
Representative) shall be applied to determine the existence and amount of any
Deficiency.  Stockholders (to the extent no included

                                      -90-
<PAGE>

in the reserve for Tax liability [rather than any reserve for deferred Taxes
established to reflect timing differences between book and Tax income] on the
Net Worth Statement [as determined to be final, conclusive and binding on all
parties pursuant to subparagraph 2(b) hereof], and if and to the extent provided
in Paragraph 16) and Buyer shall be liable on a pro rated basis (determined as
in subparagraph 13(a)(ii) above) for all expenses, costs, fees (including
reasonable attorney's and accountant's fees) incurred by Buyer, Corporation or
the Subsidiaries, as the case may be, after the Closing Date in connection with
the resolution of all Tax disputes and Tax audits with respect to any Tax period
which includes the Closing Date but which does not end on or before the Closing
Date. Stockholders shall make payment of its share of such costs, expenses and
fees if and to the extent provided in Paragraph 16.

          (h)  Except as otherwise provided in this Paragraph 19, the party
preparing a Return or required to prepare a Return shall control resolution of
any audit or investigation, and any proceedings with taxing authorities, with
respect to the Tax liability relating to such Return. However, the party
entitled to control any such audit, investigation or proceeding may, at its sole
option, extend to the party with economic liability for any Taxes at issue
therein the opportunity to assume the defense of the matter at its cost.

     20.  Further Assurances. Buyer and Stockholders (which may be through the
          ------------------
Representative) agree to execute and deliver all such other instruments and take
all such other action as any party may reasonably request from time to time,
after the date hereof and without payment of further consideration, in order to
effectuate the transactions provided for herein. The parties shall cooperate
fully with each other and with their respective counsel and accountants in
connection with

                                      -91-
<PAGE>

any steps required to be taken as part of their respective obligations under
this Agreement, including, without limitation, the preparation of financial
statements and Tax Returns.

     21.  Consent to Jurisdiction, Service of Process, Appointment of Agent.
          -----------------------------------------------------------------

          (a)  Buyer and each of the Stockholders hereby irrevocably submits to
the jurisdiction of any Delaware State or Federal court sitting in the City of
Wilmington over any suit, action or proceeding arising out of or relating to
this Agreement. Buyer and Stockholders hereby irrevocably waive, to the fullest
extent permitted by applicable law, any objection which it, they or any of them
may now have or hereafter have to the laying of the venue of any such suit,
action or proceeding brought in such court and any claim that any such suit,
action or proceeding brought in such a court has been brought in an inconvenient
forum. Buyer and each of the Stockholders agrees that, to the fullest extent
permitted by applicable law, a final judgment in any such suit, action, or
proceeding brought in such a court shall be conclusive and binding upon the
Buyer or the Stockholders, as the case may be, and may be enforced in any courts
of the jurisdiction of which the Buyer or the Stockholders, as the case may be,
are or may be subject by a suit upon such judgment, provided that service or
process is effected upon the Buyer or the Stockholders, as the case may be, in
one of the manners specified in subparagraph (b) below or as otherwise permitted
by applicable law.

          (b)  Each of the Stockholders hereby consents to process being served
in any suit, action or proceeding of the nature referred to in subparagraph (a)
above by the mailing of a copy thereof by registered or certified first-class
air mail, postage prepaid, return receipt requested, to such Stockholder at his
or its address set forth opposite their respective name on Schedule 4(a).
                                                           -------------

                                      -92-
<PAGE>

          (c)  Nothing in this Paragraph 21 shall affect the right of Buyer or
any Stockholders to serve process in any manner permitted by law or affect the
right of Buyer or any Stockholders to bring proceedings against the
Stockholders, or any of them, or the Buyer, as the case may be, in the courts of
any jurisdiction or jurisdictions.

     22.  Representative.
          --------------

          (a)  For purposes of this Agreement, the "Representative" shall mean
Quirk and Errecart.  All actions of the Representative shall be made personally
by the Representative, and no Representative shall be permitted to assign or
delegate their rights or duties, whether by operation of law or otherwise.
While both Quirk and Errecart are serving as the Representative, all decisions
of the Representative shall be made by the unanimous consent of both Quirk and
Errecart.  In the event of the death, incapacity, incompetency, disability or
resignation of either Quirk or Errecart, the remaining Representative shall
serve as the sole Representative and shall have full authority to take all
actions required or permitted to be taken by the Representative under this
Agreement.  In the event of the death, incapacity, incompetency, disability or
resignation of both Quirk and Errecart, or any substitute Representative, as the
case may be, a substitute Representative shall be promptly elected by the
Stockholders by a vote of Stockholders who owned at least a majority of the
number of Shares owned by the Stockholders in the aggregate as of the Closing
Date as set forth on Schedule 4(a).  Such election may be made by the written
                     -------------
resolution of Stockholders who owned the requisite number of shares to make such
election (provided that written notice of such election is promptly given by the
substitute Representative so elected to all Stockholders, accompanied by a copy
of such written resolution), or pursuant to a meeting of Stockholders called by
written notice by any Stockholder (or group of Stockholders) who owned at least
fifteen percent (15%) of the number of

                                      -93-
<PAGE>

Shares owned by the Stockholders in the aggregate as of the Closing Date as set
forth on Schedule 4(a). Written notice of any such meeting shall be provided to
         -------------
all Stockholders by the Stockholder(s) calling such meeting, at least five (5)
days prior to the date of the meeting. Each Stockholder shall be permitted to
participate in such meeting in person or by proxy, or by way of telephone
conference call. Prompt written notice of the election of a substitute
Representative shall be provided to Buyer by the substitute Representative so
elected, accompanied by a copy of such written resolution, and Buyer shall be
entitled to rely on the authority of any substitute Representative elected
pursuant to the procedures set forth in this subparagraph 22(a). For purposes of
this subparagraph 22(a), in the event of the death, incapacity, incompetency or
disability of any Stockholder, or in the event of any assignment and transfer
(including by operation of law) of any Stockholder's rights to payment under
this Agreement, the heirs, executors, administrators, personal or legal
representatives, successors or assigns of such Stockholder, as the case may be,
shall be entitled to vote (including to sign any written resolution) in
accordance with the number of Shares that were owned by such Stockholder as of
the Closing Date as set forth on Schedule 4(a). Upon at least ten days prior
                                 -------------
written notice to all other Stockholders and to the Buyer, any Representative
may resign at any time, with or without cause.

          (b)  In addition to, and not in substitution of, the provisions set
forth in subparagraph 22(a), each of the Stockholders hereby irrevocably
appoints Quirk and Errecart, or the survivor of them, as such Stockholders'
attorney-in-fact and agent ("Stockholders' Agent") to take any and all actions
(or not to take any or all actions), and/or to prepare, determine, calculate,
negotiate, execute and deliver any and all agreements, notices, consents,
determinations, documents and other instruments, which such Stockholder (or the
Representative on behalf of such Stockholder)

                                      -94-
<PAGE>

is required or permitted to take, prepare, determine, calculate, negotiate,
execute and/or deliver under or pursuant to this Agreement and/or as
contemplated by this Agreement, all in the name of and on the behalf of such
Stockholder, including, but not limited to, the making and execution of any
amendments to this Agreement, the giving and receipt of any notices or consents
pursuant hereto, the execution of any and all documents required to be executed
in order to complete Closing hereunder or appropriate or incidental to so
complete Closing hereunder, to calculate, determine, negotiate and give notice
of or otherwise with respect to any adjustment to any payment to be made
pursuant to this Agreement, the acceptance of service of process in connection
with any claim related to this Agreement and the compromise or settlement of any
and all disputes which may hereafter arise pursuant to any provision of this
Agreement or any matter or thing arising out of or relating to this Agreement or
the transactions provided for herein. In addition to the foregoing, each such
Stockholder agrees that any breach of any representation, warranty or agreement
on the part of Quirk and Errecart under Paragraph 5 hereunder shall be deemed to
be a joint and several breach of all Stockholders. Such appointment shall, to
the fullest extent permitted by law, survive the death, disability, incapacity,
or incompetency of any Stockholder. In the event of the incompetency,
incapacity, disability, death or resignation of both Quirk and Errecart, the
Stockholders shall appoint successors to serve as Stockholder' Agent in the
manner provided in subparagraph 22(a), and shall give Buyer written notice of
such appointment. Upon at least ten days prior written notice to all other
Stockholders and to the Buyer, any Stockholders' Agent may resign at any time,
with or without cause.

     23.  Broker.  The Corporation, pursuant to the Broker's Agreement, has
          ------
engaged Wallace Willmore Cromwell & Co., LLC (the "Broker"), as the broker to
represent it in connection with this

                                      -95-
<PAGE>

Agreement and the transactions contemplated hereby. However, as provided in
Subparagraph 5(y), the Stockholders shall be solely liable and responsible for
the fees, commissions, costs and expenses due to said Broker in connection with
this Agreement and the transactions contemplated hereby (the "Broker's Fee")
with the exception of the $25,000 retainer fee paid by the Corporation to the
Broker. Notwithstanding that the Corporation (rather than the Stockholders) is
the party to the Broker's Agreement, neither the Buyer, the Corporation nor any
Subsidiary shall have any liability or responsibility for the payment of such
Broker's Fee with the exception of the $25,000 retainer fee paid by the
Corporation to the Broker.

     24.  Miscellaneous.
          -------------

          (a)  Indulgences, Etc. Neither the failure nor any delay on the part
               ----------------
of any party to exercise any right, remedy, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or of any other right, remedy, power or privilege, nor
shall any waiver of any right, remedy, power or privilege with respect to any
occurrence be construed as a waiver of such right, remedy, power or privilege
with respect to any other occurrence. No waiver shall be effective unless it is
in writing and is signed by the party asserted to have granted such waiver.

               ----------------------
hereto are hereby incorporated by reference into, and made a part of, this
Agreement.

          (e)  Binding Nature of Agreement. This Agreement shall be binding upon
               ---------------------------
and inure to the benefit of the parties hereto and their respective successors
and assigns, except that no

                                      -98-
<PAGE>

Stockholder may assign or transfer his rights or obligations under this
Agreement other than by operation of law without the prior written consent of
Buyer (which consent shall not be unreasonably delayed, conditioned or
withheld).

          (f)  Execution in Counterparts. This Agreement may be executed in any
               -------------------------
number of counterparts, each of which shall be deemed to be an original as
against any party whose signature appears thereon, and all of which shall
together constitute one and the same instrument. This Agreement shall become
binding when one or more counterparts hereof, individually or taken together,
shall bear the signatures of (i) the Buyer and (ii) Stockholders owning, in the
aggregate, at least ninety-five percent (95%) of the outstanding Shares listed
on Schedule 4(a) based on the respective numbers of Shares listed after their
   -------------
respective names on Schedule 4(a).
                    -------------

          (g)  Provisions Separable. The provisions of this Agreement are
               --------------------
independent of and separable from each other, and no provision shall be affected
or rendered invalid or unenforceable by virtue of the fact that for any reason
any other or others of them may be invalid or unenforceable in whole or in part.
However, in the event any provision of this Agreement shall be held or declared
invalid or unenforceable in whole or in part by any court of competent
jurisdiction, such court shall (to the full extent permitted by applicable law)
revise or reform the Agreement, and/or take such other action as may be
necessary or appropriate, with respect to such invalid or unenforceable
provision so as to carry out the intent of the parties as expressed in this
Agreement in a manner that is not so invalid or unenforceable.

          (h)  Entire Agreement. This Agreement contains the entire
understanding between the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements and
understandings, inducements or conditions, express or implied,

                                      -99-
<PAGE>

oral or written, except (i) as herein contained and (ii) the Confidentiality
Agreement dated July 7, 1998, between the Buyer and Wallace Willmore Cromwell &
Co., LLC relating to the Corporation (the "Confidentiality Agreement"). In
particular, the letter of intent dated December 28, 1998, from the Buyer to the
Corporation, Quirk and Errecart, and countersigned as accepted by the
Corporation, Quirk and Errecart are superseded and terminated by this Agreement.
The Confidentiality Agreement shall be terminated, and of no further force and
effect, upon the consummation of Closing. The introductory paragraph of, and the
"Background" set forth as the premises of, this Agreement are incorporated into
this Agreement by this reference.

          (i)  Paragraph Headings. The Paragraph and subparagraph headings in
               ------------------
this Agreement are for convenience only; they form no part of this Agreement and
shall not affect its interpretation.

          (j)  Gender and Number. Words used herein, regardless of the number
               -----------------
and gender specifically used, shall be deemed and construed to include any other
number, singular or plural, and any other gender, masculine, feminine or neuter,
as the context indicates is appropriate.

          (k)  Number of Days. In computing the number of days for purposes of
               --------------
this Agreement, all days shall be counted, including Saturdays, Sundays and
Holidays; provided, however, that if the final day of any time period falls on a
Saturday, Sunday or Holiday; then the final day shall be deemed to be the next
day which is not a Saturday, Sunday or such Holiday. For purposes of this
subparagraph, "Holiday" shall mean a day, other than a Saturday or Sunday, on
which national banks are or may elect to be closed.

          (l)  Interest.  If any payment required to be made pursuant to this
               --------
Agreement or any related document referred to herein is not timely made within
10 days after receipt of notice that

                                     -100-
<PAGE>

such payment is past due, such payment shall bear interest until paid, at an
annual rate equal to the rate of interest published as the "Prime Rate" under
the category of "Money Rates" in The Wall Street Journal on the Closing Date (or
if a range is published, the highest rate in said range) plus 2%.

     IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
and delivered by their proper and duly authorized officers, on the date first
above written.

          --------------------------------------
required only to use, hold, apply, invest, reinvest, collect, pay and/or
disburse the Escrow Fund as provided in this Agreement.  The Escrow Agent shall
not be required to institute, prosecute, pursue and/or otherwise maintain any

losses, liabilities, claims, demands, actions, damages or expenses (including,
without limitation, court costs and reasonable attorneys' fees and expenses)

Agent's duties and obligations under or pursuant to this Agreement, except for
those losses, liabilities, claims, demands, actions, damages and/or expenses
determined by a final non-appealable order of a court of competent jurisdiction
to have resulted from the Escrow Agent's gross negligence, fraud or wilful
misconduct.  Without limiting the foregoing, Escrow Agent shall in no event be
liable in connection with its investment or reinvestment of any or all of the
Escrow Fund held by Escrow Agent hereunder in good faith, in accordance with the
terms and conditions of this Agreement, including, without limitation, any
liability for any delays (not resulting from Escrow Agent's gross negligence,
fraud or wilful misconduct) in the investment or reinvestment of the Escrow
Fund, or any loss of interest or other income incident to any such delays.  The
foregoing

                                      -10-
<PAGE>

indemnities in this Section shall survive the resignation or removal of the
Escrow Agent (or, if there is more than one person serving as the Escrow Agent,
the resignation or removal of any person serving as an Escrow Agent), and the
termination of this Agreement.

     11.  Reliance.  Escrow Agent shall be entitled to rely upon any order,
          --------
judgment, certification, demand, notice, instrument or other writing delivered
to Escrow Agent hereunder without being required to determine the authenticity
or correctness of any fact stated therein or the propriety or validity of the
service thereof.  Escrow Agent may act in reliance upon any instrument or
signature reasonably believed by Escrow Agent to be genuine, and may assume that
the person purporting to give receipt, consent, approval, instruction, notice,
demand, or advice, to make any statement, and/or to execute any agreement,
document or instrument arising out of or in connection with the provisions of
this Agreement, has been duly authorized to do so. Escrow Agent may conclusively
presume that the undersigned representative of any party hereto which is an
entity has full power and authority to act for that party, and to instruct
Escrow Agent on behalf of that party, unless written notice to the contrary is
delivered to Escrow Agent.

     12.  Resignation.  Any person serving as the Escrow Agent (whether or not
          -----------
any other person is also then-serving as the Escrow Agent) may at any time
resign as Escrow Agent by giving at least thirty (30) days' prior written notice
of such resignation to the Stockholders and to all other persons (if any) then-
serving as the Escrow Agent.

     13.  Option to Interplead.  If any dispute shall arise under this
          --------------------
Agreement, if the Escrow Agent has any doubts as to the proper disposition of
the Escrow Fund (in whole or in part), and/or if the Escrow Agent has any doubts
as to the proper execution or performance of the Escrow Agent's duties and/or
obligations under this Agreement, then the Escrow Agent may, in the Escrow
Agent's sole and absolute discretion, file an action in interpleader to resolve
such disagreement in any court of competent jurisdiction, and/or may deposit all
or any part of the Escrow Fund into the registry of such court; it is agreed by
all Stockholders that thereupon the Escrow Agent shall be relieved of any
further liability or obligation with respect to the Escrow Fund so deposited
into such court.  All costs and expenses (including, without limitation, court
costs and reasonable attorneys fees and expenses) incurred by the Escrow Agent
in connection therewith shall be deemed Administrative Costs and, if and to the
extent such costs and expenses exceed the then-current balance of the Escrow
Fund, the Stockholders shall indemnify and hold harmless the Escrow Agent with
respect thereto as provided in Section 10 above.  Further, the Escrow Agent
shall be fully protected in suspending all or part of its activities, duties
and/or obligations under this Agreement until a final judgment in the
interpleader action is resolved.

     14.  Successor Escrow Agent.  In the event of the death, incapacity,
          ----------------------
incompetency, disability and/or resignation of both Frank J. Quirk and Michael
T. Errecart, or any successor Escrow Agent, as the case may be, a successor
Escrow Agent shall be elected by the Stockholders by a vote of Stockholders
owning at least a majority of the Percentages.  Such decision may be made (i) by
the written resolution of Stockholders (which may be signed in counterparts),
provided that written notice of such resolution is promptly given to all other

                                      -11-
<PAGE>

Stockholders, or (ii) pursuant to a meeting of Stockholders called by any
Stockholder or group of Stockholders having at least fifteen percent (15%) of
the Percentages.  Such meeting shall take place at such reasonable location, and
on such date and at such time, as shall be determined by the Stockholder(s)
calling such meeting. Written notice of any such meeting shall be provided to
all Stockholders by the Stockholder(s) calling such meeting, at least five (5)
days prior to the date of the meeting.  Each Stockholder shall be permitted to
participate in such meeting in person or by proxy, or by way of telephone
conference call.  Written notice of the election of a successor Escrow Agent
shall be provided to Buyer, and Buyer shall be entitled to rely on the authority
of any successor Escrow Agent elected pursuant to the procedures set forth
above.  Without any further act, deed or conveyance, any successor Escrow Agent
shall become vested with all the right, title and interest to the Escrow Fund
held by the predecessor Escrow Agent.  However, such predecessor Escrow Agent
shall, promptly upon the written request of the successor Escrow Agent, execute
and deliver to such successor Escrow Agent an instrument transferring to such
successor Escrow Agent all of such predecessor Escrow Agent's right, title and
interest hereunder of such predecessor Escrow Agent.

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

                             W I T N E S S E T H :
                             - - - - - - - - - -

     WHEREAS, Buyer and Stockholders are parties to a Stock Purchase Agreement
dated as of ____________, 1999 (the "Stock Purchase Agreement") which provides
for a deposit of $2,300,000 (the "Escrow Amount") of the Purchase Price (as

     WHEREAS, Buyer and Stockholders each appoint the Escrow Agent to serve as
an escrow agent hereunder; and

     WHEREAS, the Escrow Agent is willing to serve as escrow agent pursuant to

     NOW, THEREFORE, in consideration of the mutual covenants herein contained
and other good and valuable consideration, the sufficiency and receipt of which
is hereby acknowledged, the parties hereto, intending to be legally bound, agree
as follows:

     1.   Definitions.  Capitalized terms not otherwise defined herein which are
          -----------
defined in the Stock Purchase Agreement shall have the meanings given in the
Stock Purchase Agreement,
<PAGE>

a complete and correct copy of which has been delivered to the Escrow Agent by
Buyer and the Representative.

     2.   Escrow Amount.  Pursuant to subparagraph 2(a)(ii) of the Stock
          -------------
Purchase Agreement, the Escrow Agent has provided the Buyer and the Stockholders
with the wire transfer instructions set forth on Schedule II to transfer the
                                                 -----------
Escrow Amount to the Escrow Agent at Closing.  The Escrow Agent acknowledges
receipt of $2,300,000 on the date hereof tendered by Buyer as the Escrow Amount
in accordance with subparagraph 2(a)(ii) of the Stock Purchase Agreement.  The
Buyer and the Stockholders hereby appoint the Escrow Agent as the escrow agent
hereunder, and the Escrow Agent hereby accepts said appointment and agrees to
hold the Escrow Amount and all interest and other income earned thereon
(the"Income" and, together with the Escrow Amount, the "Escrow Fund") in escrow
and to apply, invest, reinvest and disburse the Escrow Fund only in accordance
with the provisions of this Escrow Agreement.

     3.   Distribution of Escrow Fund; Disputes.
          -------------------------------------

          (a)  The amount of the Escrow Fund shall be held for the payment of
any and all Deficiencies, subject to the limitations set forth in subparagraph
16(e) of the Stock Purchase Agreement. The amount of any Deficiency shall be
determined in accordance with subparagraph 16(c)(ii) and (iii) of the Stock
Purchase Agreement.

          (b)  The Escrow Fund shall be disbursed as follows:

               (i)  From time to time Buyer may deliver signed instructions to
the Escrow Agent (the "Instructions") specifying that all or a designated
portion of the Escrow Fund be released from escrow and paid to Buyer to satisfy
any Deficiencies. Buyer shall deliver to the Representative a copy of the
Instructions concurrently with its delivery to the Escrow Agent.

                                      -2-
<PAGE>

               (ii)  If the Representative objects to the payment of any
Deficiency amount as set forth in the Instructions, it shall deliver written
notice (a "Notice of Dispute") to Buyer and the Escrow Agent within a period of
15 business days after receipt of the Instructions setting forth in reasonable
detail the reasons why the Representative is disputing the Instructions. The
Representative shall deliver to Buyer a copy of the Notice of Dispute
concurrently with its delivery to the Escrow Agent.

               (iii) If the Representative fails to deliver a Notice of Dispute
to Buyer and the Escrow Agent within said period of 15 business days, or if the
Notice of Dispute does not dispute the payment of a portion of the Deficiency
amount set forth in the Instructions (the "Undisputed Portion"), then the Escrow
Agent shall immediately pay to Buyer the amount of the payment set forth in the
Instructions or the Undisputed Portion, as applicable.

               (iv)  If the Escrow Agent receives a Notice of Dispute, the
Escrow Agent shall not pay any amounts which are being disputed unless, until
and only to the extent that the Escrow Agent (i) receives joint written
instructions signed by Buyer and the Representative regarding the payment of
funds from the Escrow Fund, or (ii) is directed to make such payment by a court
or arbitrator adjudicating such dispute.

          (c)  For as long as there shall be amounts remaining in the Escrow
Fund, on April 30 of each year, all Income earned during the preceding 12-month
period not subject to Instructions in accordance with Section 3(b) above shall
be released by the Escrow Agent and immediately paid to the Representative.
Such Income shall not be subject to such Instructions until and unless the
aggregate claims made under all Instructions exceed the Escrow Amount.

                                      -3-
<PAGE>

Any taxes incurred on account of such Income or as a result thereof shall be the
responsibility of, and be paid by, the Stockholders.

          (d) On April 30, 2002 (the "Termination Date"), all amounts remaining
in the Escrow Fund, not subject to Instructions in accordance with Section 3(b)
above, shall be released by the Escrow Agent and immediately paid to the
Representative (the "Disbursed Amount").  In the event that on the Termination
Date any amounts remaining in the Escrow Fund are subject to instructions in
accordance with Section 3(b) above, then, if and to the extent that any or all
of such amounts are later determined pursuant to Section 3 (b)(iv) above to not
be payable to Buyer (or to be payable to the Stockholders), such amounts shall
be released by the Escrow Agent and immediately paid to the Representative (and
shall also constitute a Disbursed Amount).  The Disbursed Amount shall be held,
applied, invested, reinvested, and disbursed by the Representative in accordance
with, the Stockholders' Escrow Agreement.

     4.   Investment.  The Escrow Fund shall be invested by the Escrow Agent in
          ----------
the following investments (the "Permitted Investments") from time to time as
directed in writing by the Representative:

          (a) direct obligations of the United States of America, or

          (b) money market funds authorized to invest solely in direct
obligations of the United States of America, or

          (c) such other investments as may be directed or authorized by written
instructions signed by both Buyer and the Representative.

Investment and reinvestment of the Escrow Fund shall be made only in Permitted
Investments. Interest or other income from such investments shall become part of
the Escrow Fund and shall

                                      -4-
<PAGE>

be distributed to Buyer and/or Stockholders in accordance with the provisions of
this Escrow Agreement.

     5.   Successor Escrow Agent.  If the Escrow Agent resigns or is otherwise
          ----------------------
removed with the written consent of Buyer and the Representative, a successor
Escrow Agent shall be appointed by written consent of Buyer and the
Representative. Any successor Escrow Agent shall deliver to Buyer and
Stockholders a written instrument accepting such appointment thereunder, and
thereupon it shall be entitled to all the rights and powers, and be subject to
all the duties of, the Escrow Agent contained herein. Upon the appointment of a
successor Escrow Agent as herein provided, the Escrow Agent being succeeded
shall transfer all moneys and investments which it is then holding pursuant to
this Escrow Agreement to such successor.

     6.   Expenses.  All reasonable costs, expenses and fees of the Escrow Agent
          --------
incurred in connection with the performance of its duties and obligations
hereunder, including any outside counsel fees reasonably incurred by it after
prior notice to the parties, shall be borne one half by Stockholders (in
accordance with the percentages set forth opposite each Stockholder's name on
Schedule 1 attached hereto) and one half by Buyer.
----------

     7.   Limitation of Liability.  The Escrow Agent is hereby required only to
          -----------------------
retain, invest and disburse the Escrow Fund as herein provided. The Escrow
Agent's duties are only such as are specifically provided herein and are
administrative, not discretionary. The Escrow Agent shall not be required to
determine whether or not the terms and conditions of the Stock Purchase
Agreement have been complied with by the parties. The Escrow Agent shall have no
responsibility hereunder other than to follow faithfully the instructions herein
contained or such further supplemental instructions as Buyer and the
Representative may mutually provide and

                                      -5-
<PAGE>

shall incur no liability whatsoever to Buyer or Stockholders except for gross
negligence or wilful misconduct. The Escrow Agent shall not be subject to
liability with respect to losses suffered from the investment of funds in the
Escrow Fund, except for the safekeeping of the securities in which said funds
are invested and collection of interest or other income thereon. The Escrow
Agent may consult with counsel and shall be fully protected in any action taken
in good faith in accordance with such advice. The Escrow Agent shall be fully
protected in acting in accordance with any written instructions of Buyer and the
Representative given to it hereunder and reasonably believed by it to have been
executed by the proper parties.

     8.   Indemnification.  Buyer and Stockholders (in accordance with the
          ---------------
percentages set forth opposite each Stockholders' name on Schedule I attached
                                                          ----------
hereto), jointly and severally, shall hold the Escrow Agent harmless and
indemnify the Escrow Agent against any loss, liability, expenses (including
attorney's fees and expenses), claims or demands arising out of or in connection
with the performance of its obligations in accordance with the provisions of
this Escrow Agreement, except its gross negligence or wilful misconduct.  The
foregoing indemnities in this paragraph shall survive the resignation or removal
of the Escrow Agent or the termination of this Escrow Agreement.

     9.   Option to Interplead.  If Buyer and Stockholders acting through the
          --------------------
Representative shall be in disagreement over the interpretation of this Escrow

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made as of this __ day of
April, 1999, by and between Macro International Inc., a Delaware Corporation
(the "Company") and ____________________ (the "Officer").

                             W I T N E S S E T H:
                             - - - - - - - - - -

     WHEREAS, the Company believes that it would benefit from the application of
the Officer's particular and unique skill, experience and background, and wishes
to employ the Officer as an officer of the Company; and

     WHEREAS, the parties desire by this Agreement to set forth the terms and
conditions of the employment relationship between the Company and the Officer.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
in this Agreement, the Company and the Officer agree as follows:

     1.   Employment and Duties.
          ---------------------

          (a)  The Company hereby employs the Officer as an officer on the terms
and conditions provided in this Agreement and the Officer agrees to accept such
employment subject to the terms and conditions of this Agreement. The Officer
shall serve as the Company's ____________. The Officer shall have responsibility
for [insert Officer's primary responsibilities], as well as such other officer
duties and responsibilities, as shall from time to
<PAGE>

time be determined by the Board of Directors of the Company (the "Board"), the
Chairman and Chief Executive Officer of the Company and/or the President of the
Company.

          (b)  The Officer agrees to devote his or her best efforts and
substantially all of his or her time, attention, energy and skill to performing
his or her duties hereunder. Provided that such activities shall not violate any
provision of this Agreement or the Agreement Not To Compete of even date
herewith (the "Non-Compete Agreement") or materially interfere with the
performance of his or her duties hereunder, nothing herein shall prohibit the
Officer (i) from engaging in charitable, civic, fraternal, or trade group
activities, (ii) from writing academic, trade or mainstream papers or other
publishable books, or (iii) from investing his or her assets in other entities
or business ventures.

          (c)  Without the Company's prior consent, the Officer shall not obtain
goods or services or otherwise deal on behalf of the Company with any business
or entity in which the Officer or a member of his or her family has a financial
interest or from which the Officer or a member of his or her immediate family
may derive a financial benefit as a result of such transaction, except that this
prohibition shall not apply to any public company in which the Officer or a
member of his or her family owns less than three percent of the outstanding
stock.

     2.   Term. This Agreement shall be effective upon, and the term of this
          ----
Agreement shall commence upon, the consummation of closing of the Stock Purchase
Agreement (as hereinafter defined), and shall terminate on the second (2nd)
anniversary of the date of said closing (the "Initial Term"), unless earlier
terminated in accordance with the terms of this Agreement. For purposes of this
Agreement, the "Stock Purchase Agreement" shall mean the proposed Stock Purchase
Agreement between Opinion Research Corporation, as the buyer, and

                                      -2-
<PAGE>

all or substantially all of the stockholders of the Company [(including the
Officer)], as the sellers, which is being circulated for signature
contemporaneously with execution of this Agreement. In the event the Stock
Purchase Agreement is terminated pursuant to its terms and conditions prior to
the consummation of closing thereunder, this Agreement shall thereupon be of no
further force or effect. This Agreement may be extended for an additional term
(the "Extended Term") by mutual agreement of the parties.

     3.   Compensation.
          ------------

          (a)  Base Compensation. As compensation for performing the services
               -----------------
required by this Agreement, the Company shall pay to the Officer an annual
salary ("Base Compensation") of ___________________ Dollars ($______), payable
in equal installments pursuant to the Company's customary payroll procedures in
effect for its executive personnel at the time of payment, but in no event less
frequently than monthly, subject to withholding for applicable federal, state,
and local taxes. The Officer's Base Compensation shall not be reduced during the
Term of this Agreement. The Officer's compensation shall be reviewed annually by
the Chief Executive Officer of the Company or another designee of the Board no
later than December 1 of each year, it being understood that there shall be no
obligation to increase Officer's compensation as a result of such review.

          (b)  Incentive Compensation.  In addition to Base Compensation, the
               ----------------------
Officer may receive additional compensation ("Incentive Compensation'). The
Incentive Compensation for the Initial Term shall be pursuant to the Macro
International Inc. Management Incentive Plan, adopted effective May 1, 1998. The
Incentive Compensation for any Extended Term shall be

                                      -3-
<PAGE>

pursuant to such short-term and/or long term incentive compensation programs
established from time to time by the Company.

     4.   Officer Benefits.  During the term of this Agreement the Officer and
          ----------------
his or her eligible dependents shall have the right to participate in any
retirement plans (qualified and non-qualified), pension plans, life, health and
disability insurance, cafeteria plans, or other benefit plan or program that has
been or is hereafter adopted by the Company (or in which the Company
participates), according to the terms of such plan or program.

     5.   Vacation and Leaves of Absence.  The Officer shall be entitled to [20]
          ------------------------------
vacation days during each calendar year. Vacation days will accrue, and unused
vacation days may be carried over to subsequent years, in accordance with the
Company's vacation policy in effect on the date of this Agreement. Upon any
termination of this Agreement for any reason whatsoever, accrued and unused
vacation for prior years and for the year in which this Agreement terminates
will be paid to the Officer within 10 days of such termination based on his or
her Base Compensation in effect on the date of such termination. In addition,
the Officer may be granted leaves of absence with or without pay for such
reasons as the Board in its sole and absolute discretion may determine, and
shall be entitled to the same sick leave and holidays provided to other senior
officers of the Company.

     6.   Expenses.  The Officer shall be promptly reimbursed against
          --------

     7.   Termination and Termination Benefits.
          ------------------------------------

          (a)  Termination by the Company For Cause.  The Company may terminate
               ------------------------------------
this Agreement prior to its expiration date for "Cause". In such event, the
Officer shall be paid for his or her services hereunder only his or her Base
Compensation up to the effective date of such termination. For purposes of this
Section 7(a), Cause shall mean (i) an act of dishonesty by the Officer
constituting a felony or resulting or intended to result in gain to, or personal
enrichment of, the Officer at the Company's expense, (ii) the engaging by the
Officer in misconduct which is demonstrably injurious to the Company, (iii) the
refusal of the Officer substantially to perform his or her duties hereunder,
(iv) the violation of any reasonable express direction of the Chief Executive
Officer of the Company, the Officer's supervisor or the Board or of any
reasonable rule, regulation, policy or plan established by the Company from time
to time which governs the Officer in the performance of his or her work, (v) the
use by the Officer of any illegal substance, or the use by the Officer of
alcohol or any controlled substance to an extent that it interferes with the
performance of the Officer's duties under this Agreement, and (vi) the
substantial breach by the Officer of his or her obligations in this Agreement or
in the Non-Compete Agreement.

          (b)  Termination by the Officer.  The Officer may terminate this
               --------------------------
Agreement upon 30 days' written notice to the Company (during which period the
Officer shall, if requested in writing by the Company, continue to perform his
or her duties as specified under this Agreement). In such event, the Officer
shall be paid only his or her Base Compensation for his or her services
hereunder up to the effective date of such termination.

                                      -5-
<PAGE>

          (c)  Disability.  The Company may terminate this Agreement due to the
               ----------
Officer's illness, physical or mental disability, or other incapacity, in
accordance with the Company's disability practices and policies in effect from
time to time; provided, however, that no such termination may occur unless and
until the Officer has not performed such Officer's duties under this Agreement
due to such illness, disability or other incapacity for at least six months.
However, prior to such a termination of this Agreement, the Officer shall not be
entitled to his or her Base Compensation during any period during which the
Officer is receiving sick pay or short-term disability payments from the
Company, or long-term disability insurance payments under the Company's long
term disability insurance plan.

          (d)  Death.  This Agreement shall terminate on the date of the
               -----
Officer's death. In such event the Officer's estate shall be paid his or her
Base Compensation for the remainder of the month in which such termination
occurs.

     8.   Prior Agreements, Conflicts of Interest.  The Officer represents to
          ---------------------------------------
the Company (a) that there are no restrictions, agreements or understandings,
oral or written, to which the Officer is a party or by which the Officer is
bound that prevent or make unlawful the Officer's execution or performance of
this Agreement; (b) none of the information supplied by the Officer to the
Company or any representative of the Company in connection with the Officer's
employment by the Company misstated a material fact or omitted information
necessary to make the information supplied not materially misleading; and (c)
the Officer does not have any business or other relationship that creates a
conflict between the interests of the Officer and the Company.

                                      -6-
<PAGE>

     9.   Company Property.  All materials or data of any kind furnished to the
          ----------------
Officer by the Company, or developed by the Officer on behalf of the Company, or
at the direction of the Company, or for the use of the Company, or otherwise in
connection with the Officer's employment hereunder, are and shall remain the
sole and confidential property of the Company, whichever applicable; if the
Company requests the return of such materials at any time during, at or after
the termination of the Officer's employment, the Officer shall immediately
deliver the same to the Company.

     10.  Miscellaneous.
          -------------

          (a)  Integration; Amendment.  This Agreement, together with the Non-
               ----------------------
Compete Agreement, constitutes the entire agreement between the parties hereto
with respect to the employment matters set forth herein. No amendments or
additions to this Agreement shall be binding unless in writing and signed by all
parties hereto.

          (b)  Severability.  If any part of this Agreement is contrary to,
               ------------

     1.   Employment and Duties.
          ---------------------

          (a)  The Company hereby employs the Executive as a senior executive
officer on the terms and conditions provided in this Agreement and the Executive

approval of the Board.

          (b) The Executive agrees to devote his best efforts and substantially
all of his time, attention, energy and skill to performing his duties hereunder.
Provided that such activities shall not violate any provision of this Agreement
or the Agreement Not To Compete of even date herewith (the "Non-Compete
Agreement") or materially interfere with the performance of his duties
hereunder, nothing herein shall prohibit the Executive (i) from engaging in
charitable, civic, fraternal, or trade group activities, (ii) from writing
academic, trade or mainstream papers or other publishable books, or (iii) from
investing his assets in other entities or business ventures.

          (c) Without the Company's prior consent, the Executive shall not

     2.   Term.  This Agreement shall be effective upon, and the term of this
          ----

Term") by mutual agreement of the parties.

     3.   Compensation.
          ------------

          (a) As compensation for performing the services required by this
Agreement, the Company shall pay to the Executive an annual salary ("Base
Compensation") of _______________, payable in equal installments pursuant to the
Company's customary payroll procedures in effect for its executive personnel at
the time of payment, but in no event less frequently than monthly, subject to

Executive Officer of Opinion Research Corporation, the Company's sole
shareholder, no later than December 1 of each year, it being understood that
there shall be no obligation to increase Executive's compensation as a result of
such review.

          (b) In addition to Base Compensation, the Executive may receive
additional compensation ("Incentive Compensation").  The Incentive Compensation
for the first year of the

                                      -3-
<PAGE>

Initial Term shall be pursuant to the Macro International Inc. Management
Incentive Plan, adopted effective May 1, 1998. The Incentive Compensation for
any subsequent year shall be pursuant to such short-term and/or long term
incentive compensation programs established from time to time by the Board.

     4.   Executive Benefits.  During the term of this Agreement the Executive

participates) for officers, according to the terms of such plan or program.

     5.   Vacation and Leaves of Absence.  The Executive shall be entitled to 20
          ------------------------------
vacation days during each calendar year.  Vacation days will accrue, and unused
vacation days may be carried over to subsequent years, in accordance with the
Company's vacation policy in effect on the date of this Agreement.  Upon any
termination of this Agreement for any reason whatsoever, accrued and unused
vacation for prior years and for the year in which this Agreement terminates
will be paid to the Executive within 10 days of such termination based on his
Base Compensation in effect on the date of such termination.  In addition, the
Executive may be granted leaves of absence with or without pay for such reasons
as the Board in its sole and absolute discretion may determine, and shall be
entitled to the same sick leave and holidays provided to other senior executive
officers of the Company.

<PAGE>

     7.   Termination and Termination Benefits.
          ------------------------------------

          (a) Termination by the Company for Cause.  The Company may terminate
              ------------------------------------
this Agreement prior to its expiration date for "Cause."  In such event, the
Executive shall be paid for his services hereunder only his Base Compensation up
to the effective date of such termination. For purposes of this Section 7(a),
Cause shall mean (i) an act of dishonesty by the Executive constituting a felony
or resulting or intended to result in gain to, or personal enrichment of, the
Executive at the Company's expense, (ii) the engaging by the Executive in
misconduct which is demonstrably injurious to the Company, (iii) the refusal of
the Executive substantially to perform his duties hereunder, (iv) the violation
of any reasonable express direction of the Board or of any reasonable rule,
regulation, policy or plan established by the Company from time to time which
governs the Executive in the performance of his work, (v) the use by the
Executive of any illegal substance, or the use by the Executive of alcohol or
any controlled substance to an extent that it interferes with the performance of
the Executive's duties under this Agreement, and (vi) the substantial breach by
the Executive of his obligations in this Agreement or in the Non-Compete
Agreement; provided, however, that, with respect to Sections 7(a)(iii), (iv) and
(vi), such refusals, violations, and/or breaches remain uncured for a period of
15 days after written notice thereof is received by the Executive.

          (b) Termination by the Executive.  The Executive may terminate this
              ----------------------------
Agreement upon 30 days' written notice to the Company (during which period the
Executive shall, if requested in writing by the Company, continue to perform his
duties as specified under this Agreement).  In such event, the Executive shall
be paid only his Base Compensation for his

                                      -5-
<PAGE>

services hereunder up to the effective date of such termination. In addition,
the Executive may terminate the Agreement for "Good Cause". For purposes of this
Section 7(b), Good Cause shall mean (i) a significant reduction in the level of,
or a material adverse change in, the authority, duties and responsibilities of
the Executive as a senior executive officer of the Company, or (ii) the failure
of the Company to pay to the Executive his Base Compensation or Incentive
Compensation (except in the event of a dispute as to the calculation of such
Incentive Compensation), provided that such failure shall remain uncured for a
period of 15 days after written notice thereof is received by the Company. In
the event this Agreement is terminated for Good Cause by the Executive, the
Company shall be deemed in breach of this Agreement and the Executive, in
addition to the Executive's rights under the Agreement Not To Compete, shall be
entitled to such damages with respect thereto as to which he may be entitled at
law or in equity with respect thereto.

          (c) Disability.  The Company may terminate this Agreement due to the
              ----------
Executive's illness, physical or mental disability, or other incapacity, in
accordance with the Company's disability practices and policies in effect from

          THIS LANDLORD ESTOPPEL CERTIFICATE, made this ______________ of
_______________, 1999, by __________________ ("Lessor"), to OPINION RESEARCH
                                               ------
CORPORATION, a Delaware corporation, and its respective affiliates, successors
and assigns ("ORC").
              ---

                                   RECITALS

          WHEREAS, the Lessor is the current landlord, and ____________
("Lessee") is the current tenant, under that certain Lease described on Exhibit
  ------                                                                -------
A attached hereto (the "Lease"), under which the Lessee leases from the Lessor
-                       -----
certain property and/or space in certain premises more particularly described in
the Lease (the "Leased Premises"); and
                ---------------

          WHEREAS, the Lessee intends to assign to ORC all of its right, title
and interest under the Lease.

          NOW, THEREFORE, the Lessor certifies the following to ORC and its
affiliates and to its lender financing ORC's acquisition of Lessee, and the
respective successors and assigns of the foregoing:

1.        The Lease is in full force and effect, has not been modified in any
          respect except as specially listed on Exhibit A, and constitutes the
                                                ---------
          complete agreement between the Lessor and the Lessee with respect to
          the leasing of the Leased Premises. The term "Lease" shall include any
          modification, amendments, supplements and assignments shown on Exhibit
                                                                         -------
          A. The information set forth on Exhibit A is true, correct and
          -                               ---------
          complete.

2.        Neither the Lessor nor the Lessee are delinquent or in default with
          respect to any of their respective obligations under the Lease and no
          fact or circumstance exists which, by itself or with the giving of
          notice or the passage of time, or both, would constitute a default by
          either party under the Lease or which would give the Lessor the right
          to a set-off, claim, lien or charge against the Lessee or any prior
          lessee under the Lease.

3.        The Lessee has not been granted any options, reduced or free rent, or
          other concessions or rights except as expressly set forth on Exhibit
                                                                       -------
          A.
          -
<PAGE>

4.        The Lessee is paying all rent and other charges in accordance with the
          provisions of the Lease. All base rent and additional rent, if any,
          have been paid through _________, 1999. All terms, conditions, and
          provisions of the Lease to be performed by the Lessee have been duly
          and timely performed and complied with.

5.        To the best of the Lessor's knowledge, the Lessee's rights under the
          Lease have not been assigned (in whole or in part), and the Leased
          Premises have not been sublet (in whole or in part).

6.        Lessor certifies that there is not pending against it any filing of a
          petition in bankruptcy, voluntary or otherwise, any assignment for the
          benefit of creditors, or any petition seeking reorganization or
          arrangements under the bankruptcy laws of the United States of America
          or any state thereof.

7.        Lessor hereby consents to the sale of all or substantially all of the
          stock of Lessee to ORC.

8.        The person executing this Estoppel Certificate represents and warrants
          that such person has full power and authority to do so on behalf of
          the Lessor.


          IN WITNESS WHEREOF, the undersigned has caused this Landlord Estoppel
Certificate to be duly executed as of the date first above written.

                                  WITNESSETH:

          WHEREAS, Tenant is the tenant under a lease with Landlord, dated
________________, 199___ (the "Lease"), pertaining to and covering the real

_________________________________________, which is legally described on Exhibit
                                                                         -------
A attached hereto and made a part hereof (the "Premises").
-

          WHEREAS, Lender has agreed to make a loan or has made a loan to
Landlord in the original principal amount of $_____________ (the "Loan") secured
by amongst other things, a Mortgage dated ________________ recorded
_____________ in Book ______ Page ______ in the Office of the _________________
County Recorder of Deeds, encumbering the Premises (the "Mortgage").

          WHEREAS, Landlord is the owner of the Premises.

          WHEREAS, the parties hereto desire to make the Lease subject and
subordinate to the Mortgage and any other mortgage hereafter held by Lender
affecting the Premises subject to Lender's agreement not to disturb Tenant's
rights and interests under the terms of the Lease in accordance with the terms
set forth herein.

          NOW, THEREFORE, the parties hereto, in consideration of the covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, hereby agree as follows:

1.        The Lease, as the same may hereafter be modified, amended or extended,
          and all of Tenant's right, title and interest in and to the Premises
          and all rights, remedies and options of Tenant under the Lease, are
          and shall be unconditionally subject and subordinate to the Mortgage
          and the lien thereof, to all the terms, conditions and provisions of
          the Mortgage and to each and every advance hereafter made under the
          Mortgage, and to all renewals, modifications, consolidations,
<PAGE>

          replacements, substitutions and extensions of the Mortgage, so that at
          all times the Mortgage shall be and remain a lien on the Premises
          prior and superior to the Lease for all purposes; provided, however,
          and Lender agree: (i) that neither Tenant's possession of the Premises
          nor Tenant's rights, title or interests thereunder shall be disturbed
          so long as (A) no event has occurred and no condition exists, which
          after the passage of time or the giving of notice, or both, would
          entitle Landlord to terminate the Lease or would cause, without
          further action of Landlord, the termination of the Lease or would
          entitle Landlord to dispossess Tenant from the Premises; (B) the Lease
          shall not have been previously terminated; (C) Tenant shall pay to the
          Lender or its successors or assigns all rental and other payments
          remaining due and payable to Landlord under the Lease (which are not
          subject to any claims, demands or rights of offset by Tenant due to
          any acts or omissions of Landlord or Lender, as Landlord's successor,
          or any breach of the Lease) in the amounts and at the times set forth
          in the Lease from and after the earlier of the date on which Lender
          succeeds to the interest of Landlord under the Lease or notifies
          Tenant of default under the Mortgage (a "Default"), which date shall
          be referred to as the "Succession Date" (and Landlord expressly
          consents to such payments); and (D) Tenant shall have performed all of
          its material covenants contained therein; and (ii) that Lender shall
          assume and perform all of Landlord's obligations under the Lease
          (other than as expressly set forth herein) from and after the
          Succession Date and accept the attornment of Tenant.

2.        Lender agrees that it shall automatically be liable for and perform
          all of Landlord's obligations under the Lease from and after the
          Succession Date. Except as expressly provided herein, the assignment
          of the Lease to Lender shall not obligate Lender to perform Landlord's
          obligations under the Lease.

3.        Without limiting any of the provisions of the Lease, in the event
          that, by reason of any Default on the part of the Landlord, Lender or
          their respective successors or assigns, shall succeed to the interest
          of Landlord or any successor to Landlord, then subject to the
          provisions of this Agreement including, without limitation, Paragraph
          1 above, the Lease shall nevertheless continue in full force and
          effect and Tenant shall and does hereby agree to attorn to and accept
          Lender or its successors or assigns and to recognize Lender or its
          successors or assigns as its landlord under the Lease for the then
          remaining balance of the term thereof, and Lender does hereby agree to
          assume all of Landlord's obligations under the Lease, except as
          expressly provided herein.

4.        If Lender or its successors or assigns shall succeed to the interest
          of Landlord or any successor to Landlord, neither Lender nor its
          successors or assigns shall have any liability for any act or omission
          of any prior landlord under the Lease which

                                      -2-
<PAGE>

          occurs prior to the Succession Date, nor any liability for claims,
          offsets or defenses which Tenant might have had against Landlord or
          for acts or omissions occurring prior to the Succession Date,
          provided, however, that any and all rights Tenant may have to offset
          shall remain in full force and effect and provided further that any
          and all non-monetary rights and remedies of Tenant arising under the
          Lease due to any acts or omissions of the Landlord or Lender, as
          successor to Landlord under the Lease, shall remain in full force and
          effect, including any rights to cancel or terminate the Lease.
          Further, notwithstanding the foregoing, in the event of any default by
          Landlord under the Lease which continues subsequent to the Succession
          Date, Lender shall be obligated to remedy or cure such default in the
          time and manner set forth in the Lease and Lender shall remain fully
          liable to Tenant for all acts and omissions of Lender, as Landlord.

5.        This Agreement may be executed in any one or more counterparts, each
          of which shall be deemed an original but all of which together shall
          constitute and be construed as one and the same instrument.

6.        The reasonable cost of attorneys' fees and disbursements for any legal
          action or arbitration between or among the parties arising out of any
          dispute or litigation relating to enforcement of this Agreement shall
          be borne by the party(s) against whom a final decision in rendered.

7.        All notices to be given under this Agreement shall be in writing and
          shall be deemed served upon receipt by the addressee if served
          personally or, if mailed, upon the first to occur of receipt or the
