     No Buyer Shares shall be issuable for any year in which the Baseline is not
     achieved. The rights to any Buyer Shares not issued for a specific year
     shall be forfeited and there shall be no carryover of the Buyer Shares
     designated for issuance in a specific year. In determining the Net Income
     of the Company for any fiscal period, Buyer shall prepare separate
     financial statements for the Company for each such period in accordance
     with generally accepted accounting principles and shall allocate to the
     Company for these purposes a portion of the Buyer's general and
     administrative overhead expense on the same basis that such expense is
     allocated to all of the subsidiaries and divisions of Buyer.

     2.02  Adjustment of Purchase Price.   Within 30 days after the date of
           ----------------------------
Closing, Seller shall provide Buyer with an unaudited  balance sheet of the
Company prepared as at the date of Closing (the "Closing Date Balance Sheet").
Upon receipt of the Closing Date Balance Sheet, Buyer shall make the following
calculations and adjustments:

     (a)   The aggregate book value of the assets purchased as reflected on the
Closing Date Balance Sheet must be equal to or greater than the amount reported
on the May 10, 2000, balance sheet in Exhibit B except that such aggregate book
                                      ---------
value of the assets reflected on the May 10, 2000, balance sheet and on the
closing date balance sheet may be reduced by the net book value of the vehicles
included in the Excluded Assets to be distributed or conveyed to Seller. Should
this requirement not be met, any such reduction amount by which the aggregate
book value of the Company assets as reflected on the May 10, 2000 balance sheet
in the amount of the total exceeds the aggregate amount of the assumed assets of
Seller Liabilities (the "Net Worth") as in shall cause a dollar for dollar
reduction in the Purchase Price and a corresponding reduction in the amount of
the Holdback to be paid to Seller, provided that Seller shall pay to Buyer the
amount of any such reductions in excess of the Holdback within ten days of
receiving notice from Buyer regarding the same.

     (b)  The amount by which the shareholders' equity as reflected on the May
10, 2000 balance sheet (the "Net Worth") is less than the Net Worth as reflected
on the Closing Date Balance Sheet shall cause a dollar for dollar reduction in
the Purchase Price and a corresponding reduction in the amount of the Holdback
to be paid to Seller, provided that Seller shall pay to Buyer the amount of any
such reductions in excess of the Holdback within ten days of receiving notice
from Buyer regarding the same. For these purposes, the book value of the
Excluded Assets shall be excluded from the calculation of the Net Worth in both
the May 10, 2000 balance sheet and the Closing Date Balance Sheet.

     (c)  The Holdback shall be reduced by the amount of any accounts receivable
reflected on the Closing Date Balance Sheet which are not collected and received
by Buyer within 90 days from the date of Closing. Any accounts receivable which
are not collected within such period and which thereby cause a reduction in the
amount of the Holdback shall be assigned to Seller who shall then be entitled to
take actions to collect the same for his own account and benefit.

                                      11
<PAGE>

     (d)   Should a dispute arise involving an amount greater that $5,000 in the
aggregate with regard to the review of the financial statements or collection of
accounts receivable and calculation of adjustments, if any, the Buyer's and
Seller's respective accounting firms shall select a mutually acceptable
accounting firm to make the final determination as to the calculation of such
amounts.

     (e)   Notwithstanding anything to the contrary above, it is contemplated
that prior to the Closing, the parties will review the billings, receipts and
other financial matters of the Company and may agree upon certain changes,
modifications, exceptions or variances from the above adjustment provisions,
which agreement will be set forth or summarized in a side letter or other
writing and shall control any adjustments to the Purchase Price.

     2.03  Company Liabilities.  The Company Liabilities at date of Closing
           -------------------
shall not exceed the amount of liabilities as shown on the May 10, 2000 balance
sheet in Exhibit B. Any increases in Company Liabilities without a corresponding
         ---------
increase in assets above the amount as calculated in accordance with the terms
of this Section shall cause a dollar for dollar reduction in the Purchase Price.

     2.04  Effective Time of the Transaction.  The Transaction shall not become
           ---------------------------------
effective until, and, subject to the terms and conditions of this Agreement,
shall become effective when, the actions and deliveries set forth in Sections 8
and 9 below shall have in all respects been completed.  The date and time when
the Transaction shall become effective as aforesaid is herein referred to as the

business; (d) any redemption, repurchase, or other acquisition for value of its

amount. Items included in such inventories are carried on the books of the
Company, and are valued on the Financial Statements, at the lower of cost or

item by item basis, after appropriate deduction for costs of completion,
marketing costs, transportation expense, and allocation of overhead.

                       OF REPRESENTATIONS AND WARRANTIES

applicable law and regulations or to obtain required regulatory approvals to

     11.05  Indemnification.
            ---------------

     (a)    By Seller.  Seller agrees to indemnify, defend and hold Buyer and
            ---------
its Affiliates harmless from and against any and all losses, liabilities,
claims, demands, damages, costs and expenses (including reasonable attorneys'
fees and disbursements) of every kind, nature and description (collectively,
"Claims") sustained by Buyer or any of its Affiliates based upon, arising out of
or otherwise in respect of (i) the inaccuracy of any representation or warranty
of Seller contained in this Agreement or in any certificate, agreement, document
or instrument delivered pursuant to this Agreement, or (ii) the breach of any
covenant or agreement, of Seller contained in this Agreement or in any
certificate, agreement, document or instrument delivered pursuant to this
Agreement; except, that Seller shall have no liability pursuant to Section
11.05(a)(i) for the first $15,000.00 of aggregate Claims (the "Buyer Basket").

     (b)    By Buyer.  Buyer agrees to indemnify, defend and hold Seller
            --------
harmless from and against any and all Claims sustained by Seller based upon,
arising out of or otherwise in respect of (i) the inaccuracy of any
representation or warranty of Buyer contained in this Agreement or in any
certificate, agreement, document or instrument delivered pursuant to this
Agreement, or (ii) the breach of any covenant or agreement, of Buyer contained
in this Agreement or in any certificate, agreement, document or instrument
delivered pursuant to this Agreement, or (iii) any Claim against Seller by a
creditor of the Company with respect to any debt, obligation, liability or other
commitment of the Company incurred prior to the Closing, unless and to the
extent that such Claim arises solely from any action of Seller after the
Closing; provided, however, that Buyer shall have no liability pursuant to
Section 11.05(b)(i) for the first $15,000.00 of aggregate Claims (the "Seller
Basket").

     (c)    Notification and Defense of Claims. Any party seeking information or
            ----------------------------------
reimbursement for Claims hereunder (the "Indemnified Party") shall as promptly
as practicable notify the party from which such indemnification is sought (the
"Indemnifying Party") upon which the Indemnified Party intends to base a claim
for indemnification or reimbursement hereunder; provided, however, that the
failure of an Indemnified Party so to notify the Indemnifying Party shall not
relieve the Indemnifying Party from any liability under this Agreement to the
Indemnified Party with respect to such Claim except to the extent the
Indemnifying Party is actually prejudiced or damaged by the failure to receive
timely notice. In the event of any claims for indemnification or reimbursement,
the Indemnifying Party, at its option, may assume (with legal counsel reasonably
acceptable to the Indemnified Party) the defense of any claim, demand, lawsuit
or other Proceeding brought against the Indemnified Party, which claim, demand,
lawsuit or other Proceeding may give rise to the indemnity or reimbursement
obligation of the Indemnifying Party hereunder, and may assert any defense of
any party; provided, however, that the Indemnified Party shall have the right at
its own expense to participate jointly with the Indemnifying Party in the
defense of any claim, demand, lawsuit or other Proceeding in connection with
which the Indemnified Party claims indemnification or reimbursement hereunder.
Notwithstanding the right of an Indemnified Party so to participate, the
Indemnifying Party shall have the sole right to settle or otherwise dispose of
such claim, demand, lawsuit or other Proceeding on such terms as the
Indemnifying Party, in its sole discretion, shall deem appropriate with respect
to any issue involved in such claim, demand, lawsuit

                                      33
<PAGE>

or other Proceeding as to which (i) the Indemnifying Party shall have
acknowledged the obligation to indemnify the Indemnified Party hereunder and the
settlement is solely for cash or (ii) the Indemnified Party shall have declined
so to participate and, in either case, the Indemnified Party is provided a full
and complete release of Claims.

     (d)  Survival of Representations and Warranties.  The representations and
          ------------------------------------------
warranties of the parties to this Agreement shall survive the Closing Date and
shall remain in full force and effect for a period of three years following the
Closing Date; provided, that the representations and warranties related to Tax
matters shall survive until the applicable statute of limitations for any
potential Tax liability has expired and representations and warranties related
to environmental claims shall survive indefinitely (the period during which the
representations and warranties shall survive being referred to herein with
respect to such representations and warranties as the "Survival Period"), and
shall be effective with respect to any inaccuracy therein or breach thereof (and
a claim for indemnification under Section 11.05 hereof may be made thereon) if a
written notice asserting the claim shall have been duly given in accordance with
Article 11 hereof within the Survival Period with respect to such matter. Any
claim for indemnification made during the Survival Period shall be valid and the
representations and warranties relating thereto shall remain in effect for
purposes of such indemnification notwithstanding that such claim may not be
resolved within the Survival Period. All representations, warranties and
covenants and agreements made by the parties shall not be affected by any
investigation heretofore or hereafter made by and on behalf of any of them and
shall not be deemed merged into any instruments or agreements delivered in
connection with this Agreement or otherwise in connection with the transactions
contemplated hereby.

     (e)    Exclusive Rights and Remedies. The rights and remedies provided in
            -----------------------------
this Section 11.05 shall be the exclusive rights and remedies, contractual or
otherwise, of the indemnified Persons with respect to breaches of the
representations, warranties, covenants and agreements contained in this
Agreement.

     11.06  Actions of the Parties after the Closing.  The parties hereto agree
            ----------------------------------------
that after the Closing, they will take the actions described in this Section
11.06.

     (a)    Seller acknowledges and agrees that from and after the Closing,
Buyer will be entitled to originals of all title documents and copies of all
other documents, books, records (including tax records), agreements, and
financial data of any sort relating to the Business, the Company and the Company
assets. After the Effective Time of the Transaction, Seller shall be entitled to
have access to such documents, books and records for the purpose of making
copies thereof at his own expense as he may reasonably require for his own uses
and purposes.

     (b)    In the event and for so long as any party actively is contesting or
defending against any action, suit, proceeding, hearing, investigation, charge,
complaint, claim, or demand in connection with (i) any transaction contemplated
under this Agreement or (ii) any fact, situation, circumstance, status,
condition, activity, practice, plan, occurrence, event, incident, action,
failure to act, or transaction on or prior to the Closing Date involving the
Business, the Company or the Company assets, the other party will to the extent
reasonably practicable cooperate with the contesting or defending party and its
counsel in the contest or defense, make available its personnel,

                                      34
<PAGE>

and provide such testimony and access to its books and records as shall be
necessary in connection with the contest or defense, all at the sole cost and
expense of the contesting or defending party. However, with respect to any such
information as to which the contesting or defending party may reasonably assert
that the disclosure pursuant hereto would waive a privilege, the parties will
use their reasonable efforts to develop procedures to maintain such privilege.

     (c)    Seller will not take any action that is designed or intended to have
the effect of discouraging any contractor, lessor, licensor, customer, supplier,
or other business associate of the Company from maintaining the same business
relationships with Buyer after the Closing as it maintained with the Company
prior to the Closing. The Seller will refer all customer inquiries relating to
the Business to Buyer from and after the Closing.

     (d)    Seller agrees that after the Closing Date any facts, information,
know-how, processes, trade secrets, customer lists or confidential matters that
relate in any way to the Company shall be maintained in confidence and shall not
be divulged by Seller to any party unless and until they shall become public
knowledge (other than by disclosure by Seller or the Company's officers,
employees or agents) or as required by law. Seller further agrees to use his
best efforts to ensure that none of the Company's officers, employees or agents
divulge any such confidential information to a third party or use the same for
the benefit of Seller, any such officer, employee or agent or any other third
party, unless and until it shall have become public knowledge (other than by
disclosure by Seller or the Company's officers, employees or agents). Buyer
shall have the right to interview the Company's employees for the purpose of
obtaining information concerning the Company and Seller hereby waives any right,
claim, or cause of action, express or implied, which Seller may have against the
Company or any of the Company's officers, employees or agents by reason of any
such officer, employee or agent divulging to Buyer after the Closing Date any
facts, information, know-how, processes, trade secrets, customer lists or
similar confidential matters that relate to the Company, the Business or the
Company assets.

     (e)    From and after the Closing Date Seller agrees not to use the name
"Hopkins Appraisal Services" or any deceptively similar name or related
Proprietary Rights and shall provide to or at the request of Buyer any consent,
waiver or approval that may be required or advisable in connection with Buyer's
use of such name.
