         1.2 Effects of the Merger. This Agreement and the Agreement of Merger,
the terms and conditions of which are incorporated by reference herein and made

                  (a) The separate existence of Transitory Subsidiary shall
cease;

                  (b) Surviving Corporation shall become a wholly owned
subsidiary of Buyer; and

                  (c) Surviving Corporation shall possess all the rights,
privileges, immunities, powers, franchises, properties and assets of the Company

         1.5 [Intentionally Omitted]

         1.6 Conversion of Stock. Subject to Section 1.12 and the provisions
below and in the Agreement of Merger, at the Effective Time, by virtue of the

<PAGE>   9

shall, by virtue of the Merger, be converted into the right to receive, without
interest, $29.3496 in cash, as adjusted in the manner described in Section 1.7
of this Agreement and payable in the manner described in Section 2.2, and
subject to the provisions of Section 11.2 of this Agreement and the provisions
of the Escrow Agreement;

                  (b) Dissenting Shares. The portion of the Purchase Price
attributable to Dissenting Shares that arises from the exercise of appraisal
rights for Common Stock outstanding immediately prior to the Effective Time (the
"Dissenters Proceeds") shall be payable in the manner described in Sections 2.2
and 2.4, and such Dissenters Proceeds shall be subject to the provisions of
Section 11.2 of this Agreement and the provisions of the Escrow Agreement.

         1.7 Adjustments to Purchase Price Paid to Holders of Common Stock. The
portion of the Purchase Price payable to the holders of Common Stock shall be
(i) decreased dollar-for-dollar by the amount of Assumed Debt (as described in
Section 5.7), and (ii) increased by the amount of the Benefit Expense Proration.
(For purposes of this Agreement, the "Benefit Expense Proration" shall equal the
expense paid in advance by the Company and its Subsidiaries with respect to the
Benefit Plans for the month in which the Closing occurs, prorated for the number
of days that elapse in such month until the Closing Date). In addition, the
portion of the Purchase Price payable to the holders of Common Stock shall be
adjusted for (x) the difference between U.S. $191,361 and the Company's Net
Working Capital (as defined on Schedule 1.7) as of the Closing Date (the
"Adjustment Amount"), and (y) the difference between U.S. $830,904 and the
Company's cash and cash equivalents as of the Closing Date (the "Cash Adjustment
Amount"). Net Working Capital shall be calculated in accordance with the
accounting principles set forth on Schedule 1.7 attached hereto (collectively,
the "Accounting Principles.

         1.8 Adjustment Procedure

                  (a) The Shareholder Representative will prepare and will cause
the Company's certified public accountants to review consolidated financial
statements ("Closing Financial Statements") of the Company as of the Closing
Date and for the period from the date of the Interim Balance Sheet (as defined
in Section 3.6 below) through the Closing Date, including a computation of the
Company's cash and cash equivalents (the "Final Cash Amount"), Net Working
Capital, Assumed Debt and Benefit Expense Proration as of the Closing Date. The
Shareholder Representative will deliver the Closing Financial Statements
(together with detail and working papers reasonably required for Buyer's review
including tax accruals for the short tax period ending at the Closing) to the
Buyer within sixty days after the Closing Date. If, within thirty days following
delivery of the Closing Financial Statements, the Buyer has not given the
Shareholder Representative notice of its objection to the Closing Financial
Statements (such notice must contain a detailed statement of the basis of the
Buyer's objection), then the Company's Final Cash Amount and Net Working Capital
and



                                      -3-
<PAGE>   10

Assumed Debt and Benefit Expense Proration reflected in the Closing Financial
Statements will be used in computing the amount to be paid by Buyer for the
Company's cash and cash equivalents and the Adjustment Amount, the amount of the
Assumed Debt and the Benefit Expense Proration amount. If the Buyer gives such
notice of objection, then the issues in dispute will be submitted to such
nationally recognized accounting firm (other than Arthur Andersen) as the
Parties may designate (the "Accountants"), for resolution. If issues in dispute
are submitted to the Accountants for resolution, (i) the Buyer and the
Shareholder Representative each will furnish to the Accountants such workpapers
and other documents and information relating to the disputed issues as the
Accountants may request and are available to the Shareholder Representative and
the Buyer or its Subsidiaries (or its independent public accountants), and will
be afforded the opportunity to present to the Accountants any materials relating
to the determination and to discuss the determination with the Accountants; (ii)
the determination by the Accountants, as set forth in a notice delivered to the
Shareholder Representative and the Buyer by the Accountants, will be made within
sixty days of submission and will be binding and conclusive on the Buyer and the
Company Shareholders; and (iii) the Buyer and the Company Shareholders will each
bear one-half of the fees of the Accountants for such determination.

                  (b) On the tenth business day following the final
determination of the Cash Adjustment Amount, the Adjustment Amount, the amount
of the Assumed Debt and the Benefit Expense Proration, if the Purchase Price, as
adjusted in the manner provided herein, is greater than the Estimated Purchase
Price paid by the Buyer pursuant to Section 1.9, the Buyer will deposit with the
Exchange Agent the difference together with the Net Working Capital Holdback
described in Section 2.2(a)(ii), and if such Purchase Price is less than such
Estimated Purchase Price (the "Purchase Price Shortfall"), (i) the Escrow Agent
will pay to the Buyer the amount by which the Purchase Price Shortfall exceeds
the Net Working Capital Holdback, if the Purchase Price Shortfall is greater
than the amount of the Net Working Capital Holdback, or (ii) the Buyer shall
deposit with the Exchange Agent the amount by which the Net Working Capital
Holdback exceeds the Purchase Price Shortfall, if the amount of the Net Working
Capital Holdback is greater than the Purchase Price Shortfall. All payments will
be made together with interest at 8% per annum beginning on the Closing Date and
ending on the date of payment. Deposits made with the Exchange Agent shall be
made by wire transfer of immediately available funds and will be allocated to
the holders of Common Stock (and the interest in the Common Stock represented by
Dissenting Shares) as provided in Section 1.6. Payment to the Buyer (other than
under its representative right attributable to Dissenting Shares) shall be made
out of the Escrow Fund (as defined in the Escrow Agreement) pursuant to the
terms of the Escrow Agreement and be debited against the amount otherwise
payable to the holders of Common Stock and the interest in the Common Stock
represented by Dissenting Shares from the Escrow Fund.

         1.9 Payment of the Closing Estimated Purchase Price. Not later than two
(2) business days prior to the Closing Date, the Company shall prepare and
deliver to the Buyer a statement setting forth a good faith estimate of (i) the
Net Working Capital as of the Closing Date (the "Estimated Net Working Capital")
prepared in accordance with the Accounting Principles, (ii) the amount of
Assumed Debt as of the Closing Date (the "Estimated Assumed Debt"), and (iii)
the amount of the Benefit Expense Proration as of the Closing date (the
"Estimated Benefit Expense Proration"). The "Estimated Purchase Price" shall
mean an amount equal to the following:

                           (i) if the Estimated Net Working Capital is greater
         than or equal to $191,361, then the Purchase Price plus (a) the excess
         of the Estimated Net Working Capital over $191,361, and (b) the
         Estimated Benefit Expense Proration, less the Estimated Assumed Debt;
         and

                           (ii) if the Estimated Net Working Capital is less
         than $191,361, then the Purchase Price plus the Estimated Benefit
         Expense Proration, less the excess of $191,361 over the Estimated Net
         Working Capital and less the Estimated Assumed Debt.

         1.10 Approval of Company Shareholders. The Company shall, as soon as
practicable after the Company's receipt of consents of a majority of the holders
of the Common Stock to the adoption of this Agreement, but in no event later
than five (5) days after the date hereof, distribute a statement (the
"Shareholder Information Statement") and any other such notices as may be
required by Section 1201 of the GCL to all holders of the Common Stock (the
"Shareholders"). Such Shareholder Information Statement shall give notice of the
Company's receipt of consents of a majority of the holders of the Common Stock
to the adoption of this Agreement and notice of the appraisal rights of the
Company Shareholders as required by Section 1301 of the GCL and request adoption
of this Agreement.

         1.11 Accounts Receivable. At the Closing, the accounts receivable of
the Company and its Subsidiaries as of the Closing Date (the "Accounts
Receivable"), less a reserve placed in a sub-account of the Escrow in an amount
equal to ten percent (10%) of their face amount (the "A/R Reserve Escrow"),
shall be determined. As of the date four (4) months (the "Collection Period")
following the Closing, Buyer shall determine in good faith the amount, if any,
by which the Accounts Receivable exceed the actual collection of such Accounts
Receivable after applying any applicable customer deposits or credits made or
given prior to the Closing Date with respect to such Accounts Receivable or the
transactions giving rise thereto (the "Accounts Receivable Deficiency") at the
expiration of such Collection Period. Buyer shall, within twenty (20) days
following the expiration of such Collection Period, provide the Shareholder
Representative with reasonably satisfactory evidence of the amount of the
Accounts Receivable Deficiency and the components thereof, and subject to the
provisos below, shall cause the Surviving Corporation and its Subsidiaries, or
their



                                      -5-
<PAGE>   12

successors or assigns, to assign to the Shareholder Representative any such
Accounts Receivable which have not been collected within the Collection Period,
and any rights to interest and/or penalties relating thereto, provided that:

         (i) Buyer may elect to cause the Surviving Corporation to retain any
such Accounts Receivable, in which event the aggregate amounts of such Accounts
Receivable shall be excluded in determining the Accounts Receivable Deficiency;
or

         (ii) Buyer may elect to return the uncollected Accounts Receivable to
the Shareholder Representative at their book value to determine the Accounts
Receivable Deficiency.

Except where (i) a customer that owes an Account Receivable is on a COD basis on
the day of the Closing, or (ii) Buyer in good faith, causes the Surviving
Corporation or its Subsidiaries, or their successors in interest, to convert a
customer to COD basis after Closing, the first payments received by the
Surviving Corporation or its Subsidiaries, or their successors in interest, from
such customer shall be applied to the payment of the oldest outstanding balance
of such customer's account. Payments made to the Surviving Corporation or its
Subsidiaries, or their successors in interest, by any such customer for products
sold by the Surviving Corporation or its Subsidiaries, or their successors in
interest, on a COD basis shall not be applied to the Accounts Receivable that
existed prior to the Closing, but shall be retained exclusively by the Surviving
Corporation or its Subsidiaries, or their successors in interest. Buyer agrees
to notify the Shareholder Representative at the time it causes the Surviving
Corporation or its Subsidiaries, or their successors in interest, to place any
customer on a COD basis.

Buyer agrees to use its best efforts to collect Accounts Receivable, but shall
not be required to cause the Surviving Corporation or its Subsidiaries to
institute legal action for any collection.

On or about the date three (3) months after the Closing Date, Buyer shall
provide the Shareholder Representative with a status report setting forth in
reasonable detail Buyer's collections of, and collection efforts with respect
to, the Accounts Receivable and confer with the Shareholder Representative
regarding appropriate steps to be taken to collect unpaid Accounts Receivable.

                  Within 25 days after the Shareholder Representative's receipt
of Buyer's written notice of the Accounts Receivable Deficiency, Buyer shall
receive from the A/R Reserve Escrow the Accounts Receivable Deficiency, with
interest on such Accounts Receivable Deficiency as earned on such amount under
the A/R Reserve Escrow. In the event that the A/R Reserve Escrow is insufficient
to satisfy the Accounts Receivable Deficiency, then such insufficiency shall be
deducted from the Escrow Fund. In the event the amount of the A/R Reserve Escrow
exceeds the



                                      -6-
<PAGE>   13

Accounts Receivable Deficiency, then the Escrow Agent shall promptly transfer
the excess to the Shareholder Representative Escrow and Buyer shall so instruct
the Escrow Agent.

         1.12 Dissenting Shares. Notwithstanding anything in this Agreement to
the contrary, Common Stock outstanding immediately prior to the Effective Time
and held by a holder of record who has delivered a written demand for purchase
of such shares by the Company in accordance with Section 1301 of the GCL
("Dissenting Shares") shall not be converted or otherwise treated as provided in
Section 1.4 hereof, but shall have the rights afforded to such holder under
Section 1301 of the GCL, unless and until such holder fails to perfect or
effectively withdraws or otherwise loses his right to require the Company to
purchase such shares under the GCL. If, after the Effective Time, any such
holder fails to perfect or effectively withdraws or otherwise loses his right to
require the Company to purchase such holder's shares, such Dissenting Shares
shall thereupon be treated as if they had been converted as of the Effective
Time into the right to receive the merger consideration as provided in Section
1.6(a) or Section 1.6(b) hereof, as appropriate, and to which such holder is
entitled, without interest thereon. The Company shall give Buyer prompt notice
of any demands received by the Company for purchase of Common Stock by the
Company pursuant to Section 1301 of the GCL and prior to the Effective Time,
Buyer shall have the right to participate in all negotiations and proceedings
with respect to such demands. Prior to the Effective Time, the Company shall
not, except with the prior written consent of Buyer, make any payment with
respect to, or offer to settle, any such demands.

         1.13 Escheatment. Notwithstanding anything in this Agreement to the
contrary, neither the Exchange Agent nor any Party hereto shall be liable to a
former Shareholder for any cash delivered to a public official pursuant to
applicable escheat or abandonment property laws.

                                   ARTICLE II

<PAGE>   17

(which shall be in customary form and shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
proper delivery of the Certificates to the Exchange Agent) and (ii) instructions
for use in effecting the surrender of the Certificates in exchange for cash to
which such holder is entitled pursuant to this Agreement. Upon surrender to the
Exchange Agent of a Certificate for cancellation, together with a letter of
transmittal, duly executed and completed in accordance with the instructions
hereto, and such other documents as reasonably may be required pursuant to such
instructions, the holder of such Certificate shall be entitled to receive in
exchange therefor a check in an amount equal to the Preliminary Merger
Consideration that such holder has the right to receive pursuant to this
Agreement in respect of the Common Stock formerly represented by the
Certificates tendered by such holder, and the Certificate so surrendered shall
forthwith be canceled. The Exchange Agent shall report periodically to Buyer and
the Shareholder Representative on a weekly basis as to the status of the payment
procedure until all payments have been made.

                  The Preliminary Merger Consideration shall be payable to the

Stock which is not registered in the transfer records of the Company, cash to
which such holder is entitled pursuant to this Agreement may be delivered to a
transferee if the Certificate representing such shares of Common Stock is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
2.4, each Certificate shall be deemed at all times after the Effective Time to
represent only the right to receive upon such surrender the applicable
consideration described in this Agreement, without interest thereon. From and
after the Effective Time, the holders of Common Stock outstanding immediately
prior to the Effective Time shall cease to have any rights with respect thereto,
except for the right to receive such cash upon surrender of the Certificates
representing Common Stock. The Exchange Agent shall be authorized to pay the
cash attributable to any certificate theretofore issued which has been lost or
destroyed, upon receipt of (i) satisfactory evidence of ownership of the shares
of Common Stock represented thereby and (ii) in Buyer's reasonable discretion,
either an appropriate bond or appropriate indemnification. The expenses of the
Exchange Agent shall be borne equally by Buyer and the Company, with the
Company's portion to be paid or accrued on the Closing Balance Sheet.

         2.5 Additional Action. The Surviving Corporation may, at any time after
the Effective Time, take any action, including executing and delivering any
document, in the name and on behalf of either Surviving Corporation or the
Transitory Subsidiary, in order to consummate the transactions contemplated by
this Agreement.

         2.6 Certificate of Incorporation. The Articles of Incorporation of the
Company shall be amended in the Merger to read in their entirety as set forth on
Exhibit H hereto and, as amended, shall be the Articles of Incorporation of the
Surviving Corporation until thereafter amended in accordance with the provisions
thereof and hereof and applicable law.

         2.7 Bylaws. The bylaws of the Surviving Corporation shall be the same
as the bylaws of the Transitory Subsidiary immediately prior to the Effective
Time, except that the name of the corporation set forth therein shall be changed
to California Western Gas Company.

         2.8 Directors and Officers. The directors of the Transitory Subsidiary
shall become the initial directors of the Surviving Corporation as of the
Effective Time, and the officers of Transitory Subsidiary immediately prior to
the Effective Time shall be the initial officers of the Surviving Corporation,
in each case until their respective successors are duly elected or appointed and
qualify.

         2.9 No Further Rights. Except as provided in Section 1.12 herein or by
law (i) from and after the Effective Time, no Common Stock shall be deemed to be
outstanding, and (ii) the holders of shares of Common Stock shall cease to have
any rights with respect thereto.

                                  ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company hereby represents and warrants to the Buyer that
except as provided in the Schedules referred to herein:

         3.1 Authority. Subject to adoption of this Agreement by its
Shareholders, the Company has full corporate power and authority and has taken
all corporate action necessary to execute and deliver this Agreement, the Escrow
Agreement and to carry out the transactions contemplated hereby and thereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly approved by the
Board of Directors of the Company. This Agreement has been duly and validly
executed and delivered by the Company and constitutes a valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, subject, however, to the approval of the Shareholders and except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or other laws relating to or limiting creditor's rights or by
equitable principles generally. Upon the adoption of this Agreement by the
holders of a majority of the outstanding Common Stock, the Merger Documents when
filed with the Secretary of State of California, are legally sufficient to
effect the Merger of the Transitory Subsidiary into the Company as contemplated
by the Agreement of Merger.



                                      -12-

         3.2 Organization. The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of California and has
full power and authority to own, lease and operate its assets and to carry on
the Business. The Company is duly licensed, registered and qualified to do
business as a foreign corporation and is in good standing in all jurisdictions
in which the ownership, leasing or operation of its assets or the conduct of its
business requires such qualification, except where the failure to be so
licensed, registered or qualified would not have a material adverse effect upon
its assets or operations. Schedule 3.2 sets forth each state or other
jurisdiction in which the Company is licensed or qualified to do business.

         3.3 No Conflict. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby will not result in the
creation of any Lien or, except as set forth in Schedule 3.3, the termination or
acceleration of any indebtedness or other obligation of the Company, and are not
prohibited by, do not violate or conflict with any provision of, and do not
constitute a default under or a breach of (a) the Articles of Incorporation or
Bylaws of the Company, (b) any Material Contract (as defined in Section 3.19
below), (c) any order, writ, injunction, decree or judgment of any court or
governmental agency, or (d) any law, rule or regulation applicable to the
Company. No approval, authorization, registration, consent, notice, order or
other action of or filing with any Person, including any Governmental Entity, is
required for the execution and delivery by the Company of this Agreement or the
consummation of the transactions contemplated hereby, other than as set forth on
Schedule 3.3.

         3.4 Capitalization and Shareholders of the Company. The authorized
capital stock of the Company consists of 500,000 shares of Common Stock. As of
the date hereof, 63,027 shares of Common Stock are duly issued, outstanding,
fully paid and non-assessable, and were not issued in violation of any
preemptive, subscription or other right of any Person to acquire securities.
There is no outstanding subscription, option, convertible or exchangeable
security, preemptive right, warrant, call or agreement (other than this
Agreement) relating to the Common Stock or other obligation or commitment to
issue any shares of Common Stock. There are no voting trusts or other
agreements, arrangements or understandings applicable to the exercise of voting
or any other rights with respect to any Common Stock. On or prior to the
Closing, the Company shall deliver to the Buyer a schedule which, to the
Company's Knowledge, shall be a true and correct listing of each shareholder of
the Company, and such shareholder's address, together with the number and type
of shares held by such holder as of the date thereof, based on the Company's
current shareholder records (the "Shareholder List").

         3.5 Subsidiaries. The Company is the record and beneficial owner of a
majority of the outstanding capital stock of the corporations, if any, listed on
Schedule 3.5 attached hereto (such majority owned corporations, if any, are
referred to in this Agreement and the Schedules hereto as the "Subsidiaries").
The equity capital stock



                                      -13-
<PAGE>   20

of each Subsidiary is as set forth in Schedule 3.5. The number of issued and
outstanding shares of capital stock of each Subsidiary owned beneficially and of
record by the Company are set forth on Schedule 3.5 and all of such shares are
owned free and clear of any Liens and have been duly authorized, validly issued,
are fully paid and non-assessable, and have not been issued in violation of any
preemptive rights of shareholders. No options, warrants or other rights to
acquire, sell or issue shares of capital stock of any of the Subsidiaries,
whether upon conversion of other securities or otherwise, are outstanding.
Except for the Company's ownership of the capital stock of the Subsidiaries and
except as may be set forth on the Interim Balance Sheet, neither the Company nor
any Subsidiary, either directly or indirectly, owns an equity interest in any
other corporation, limited liability company, partnership or other entity other
than as set forth on Schedule 3.5, which Schedule accurately describes the
nature of the Company's or its Subsidiary's interest in such entity and the
number and type of shares of stock or other equity interest held in such
entity.) With respect to the shares held by the Company in California Western
Gas Company as shown on Schedule 3.5, such shares are owned by the Company free
and clear of any Liens, have been duly authorized, validly issued, are fully
paid and non-assessable, and have not been issued in violation of any preemptive
rights of shareholders, and there are no options, warrants or other rights to
acquire or sell such shares.

the unaudited consolidated balance sheets of the Company and its Subsidiaries as
of each of the fiscal years ended June 30, 2000, 1999 and 1998, and the

balance sheet of the Company and its Subsidiaries as at April 30, 2001 (the

notes thereto fairly present in all material respects the financial position of
the Company and its Subsidiaries as of the respective dates thereof and such
statements of income and the notes thereto fairly present in all material
respects the results of operations for the periods therein referred to, all in
accordance with GAAP but subject, in the case of interim financial statements,
to normal year-end adjustments.

         3.7 Subsequent Events. Except as set forth on Schedule 3.7, since May
1, 2001, the Company has been operated only in the ordinary course of business
and there has not been any (i) material adverse change in the assets,
liabilities, financial condition, earnings, properties, business, customer base

ERISA) ("Pension Plans"); (ii) any bonus, profit sharing, deferred compensation,
incentive or other compensation plan or arrangement; (iii) any termination or
severance agreements or contracts; or (iv) any other employee fringe benefit

and any related trust agreement or annuity contract or any other funding
instrument complies in all material respects with the provisions of applicable
law, including ERISA and the Code, and all necessary governmental approvals for
the Benefit Plans have been obtained. There are no actions, suits, or claims
(other than routine claims for benefits) pending or, to the Company's Knowledge,
threatened, against or with respect to any Benefit Plan or the assets of any
such Benefit Plan, and to the Company's Knowledge no facts exist that would
likely give rise to any actions, suits or claims (other than routine claims for
benefits) against such Benefit Plans or assets. Neither the Company, nor, to the
knowledge of the Company, any other "disqualified person" or "party in interest"
(as defined in Section 4975(e)(2) of the Code and Section 3(14) of ERISA,

complete list of each license, permit, certificate, approval, exemption,
franchise, registration or authorization issued to the Company or a Subsidiary
by a governmental body or agency where the failure to have such license or
permit would prohibit the Company or any Subsidiary from carrying on the
Business as presently conducted (collectively, the "Licenses and Permits"),
other than certain Cal OSHA Division of Industrial Safety Permits ("DIS
Permits") obtained by the Company or its subsidiaries in the normal course of
business. The Licenses and Permits and material DIS Permits are valid and in
full force and effect and there are not pending nor, to the Company's Knowledge,
threatened, any proceedings which would likely result in the termination,
revocation, limitation or impairment of any License or Permit or material DIS
Permit. The Licenses and Permits and DIS Permits constitute all material
licenses and permits necessary under applicable laws, rules and regulations for

<PAGE>   27

                  (b) Any other contract, commitment, agreement, arrangement or
understanding related to the Business which (i) provides for payment or
performance by any party thereto involving an aggregate annual payment or
performance obligation of $10,000 or more, (ii) is not terminable without

provided, however, that the Company shall not be required to disclose the
identity of any individual customer, reseller or other agent or provide any
customer lists to the Buyer (but the other provisions of any Material Contract
shall be provided) until all conditions to Closing have been satisfied or
waived. To the Company's Knowledge, each Material Contract is in full force and
effect and is valid, binding and enforceable in accordance with its terms. No
event has occurred which is or, after the giving of notice or passage of time,
or both, would constitute a default under or a breach of any Material Contract
by the Company or any Subsidiary, or, to the Company's Knowledge, by any other
party. There is no Lien on the Company's or any Subsidiary's interest under any
Material Contract.

         3.20 Taxes.

"Tax") required to be paid by it through the date hereof, and shall timely pay
any Taxes required to be paid by it on or prior to the Closing Date for periods
ending on or before the Closing Date. The provisions for Taxes (as opposed to
any reserve for deferred taxes established to reflect timing differences between
book and tax income), including federal, state and local income taxes on the
Interim Balance Sheet are sufficient for the payment of all Taxes due with
respect to the conduct of the Business of the Company and the Subsidiaries and
the effect of the consummation of the Related Transactions at the Closing up to
and through the date of the Interim Balance Sheet and the Closing Date, but
excluding the effects of any transaction that occurs on the Closing Date after
the Closing contemplated by this Agreement and the closing of the Related
Transactions have occurred (for purposes of eliminating doubt, the transactions
the effects of which shall be excluded pursuant to the immediately preceding
phrase beginning with the word "but" include Buyer's liquidation of the Company
by merger or otherwise upon or after the Closing under this Agreement, the
effects of any such liquidation being solely the responsibility of Buyer
notwithstanding any provision of this Agreement that might be construed to the
contrary).

Subsidiaries, except as set forth on Schedule 3.20, to the Company's Knowledge,
no audit is in progress, and no extension of time is in force with respect to
any date on which any such return for Taxes was or is to be filed and no waiver
or agreement is in force for the extension of time for the assessment or payment
of any Tax, and (ii) copies of such returns supplied to Buyer in the data room
(i.e. for the tax years 1999, 1998, 1997 and 1996) are true and correct in all
material respects).

                  (e) Except as set forth on Schedule 3.20, neither the Company

previously engaged in a trade or business in any foreign country. Neither the

by the Company or a Subsidiary (i) would not permit the other party to terminate
such contract, or (ii) have a material adverse effect on the Company or any
Subsidiary. No products distributed, sold or delivered by the Company or a
Subsidiary prior to the date of this Agreement are now subject to any guarantee,
express warranty, claim for product liability, or patent or other indemnity,
other than those set forth or described in Schedule 3.21.

Company's Knowledge, threatened with any action, suit, proceeding, complaint,
charge, hearing, investigation or arbitration or other method of settling
disputes or disagreements (other than environmental claims as to which Section
3.23 applies). As of the date hereof, neither the Company nor any Subsidiary has
received notice of any investigation threatened by any Governmental Entity. As

<PAGE>   37

transactions contemplated hereby and such problem has not been resolved within

Debt assumed by Buyer at the Closing pursuant to this Section 5.7 ("Assumed
Debt"), shall be deducted dollar-for-dollar from the Purchase Price otherwise to
be deposited with the Exchange Agent at the Closing. Except as set forth on

                               COVENANTS OF BUYER

         6.1 Intentionally Omitted.

         6.2 Records and Documents. For seven (7) years following the Closing
Date, the Buyer shall grant to the Shareholder Representative, at his written
request, and at the Shareholders' expense, access to and the right to make
copies of those Company records and documents that relate to any period on or
before the Closing Date and as may be reasonably necessary or useful in
connection with the Shareholder Representative's affairs after the Closing,
including the preparation of Tax returns. The Buyer shall notify the Shareholder
Representative within five (5) business days after receiving notice of any Tax
audits of the Company or any Subsidiary for any period beginning prior to the
Closing Date. Except as provided in Section 6.8, the Buyer shall permit the
Shareholder Representative to control such audits and any related settlements
with respect to periods beginning on or prior to the Closing Date. The Buyer
will cause the Company to promptly forward to the Shareholder Representative all
information and materials regarding Excluded Assets.

         6.3 Buyer's Efforts. The Buyer shall use its reasonable commercial
efforts to consummate the transactions contemplated by this Agreement and shall
not take any action inconsistent with its obligations hereunder or which could
hinder or delay the consummation of the transactions contemplated hereby. From
the date hereof through the Closing Date, the Buyer shall use its reasonable
commercial efforts to fulfill the conditions to its obligations hereunder.

         6.4 Confidentiality. The Buyer agrees to maintain strict
confidentiality of all information furnished in connection with the transactions
contemplated hereby, all in accordance with the terms and conditions of the
Confidentiality Agreement dated as of October 18, 2000 to which the Buyer is a
party (the "Confidentiality Agreement"). In the event that the transactions
contemplated hereby are not consummated, the Buyer shall return to the Company
all written information furnished to it (and an executive officer shall certify
in writing as to such return) and will not thereafter use such information for
any purpose whatsoever or permit any such confidential information to be made
publicly available.

         6.5 Employee Matters. Except as described in Schedule 6.5, the Buyer
agrees to cause the Surviving Corporation to continue to employ for a period of
at least two months after the Closing Date those Employees of the Company who
are Employees in good standing as of the Closing Date, unless good cause exists
for



                                      -32-
<PAGE>   39

termination. Such employment shall be at least at the same salaries or hourly
rates as presently being paid by the Company, and while such employment shall be
on an "at will" basis, each such Employee will be evaluated by the Buyer by
standards no different than those applied by the Buyer to its other employees
performing similar job functions. The Buyer agrees, to the fullest extent
permitted by applicable law, that (i) all Employees of the Company and the
Subsidiaries shall be entitled to participate in the employee benefit plans,
including group health, life and disability plans, presently maintained by the
Buyer (true and correct copies of which have been furnished by the Buyer to the
Company) pursuant to the terms of those plans, (ii) the Buyer will not amend
such employee benefit plans or permit any such plans to be amended in any way
materially detrimental to the employees of the Company and the Subsidiaries
during the two month period following the Closing Date, except for general and
uniform changes applying to all employees covered by such plans, and (iii) with
respect to any "employee welfare benefit plan" (as defined in Section 3(1) of
ERISA) maintained or sponsored by Buyer, any waiting period for eligibility will
be prorated for each Employee, to the extent such Employee was covered under a
similar plan maintained or sponsored by the Company or any Subsidiary, as
applicable, on the Closing Date. Without limiting the foregoing, such Employees
will receive credit for years of service with the Company and the Subsidiaries
in determining vacation and sick days including credit for any accrued and
unused sick and vacation time under the Company's or any Subsidiary's sick and
vacation policy, as applicable. The Buyer shall cause the Company to comply with
the WARN Act to the extent applicable and be solely responsible for furnishing
the required notice of any "plant closing" or "mass layoff" which may occur
after Closing, and the Buyer shall indemnify and hold those individuals who were
officers and directors of the Company at or prior to the Closing harmless for
any inadequacy of such notice and for any liabilities under or relating to the
WARN Act which arise in connection with actions or omissions occurring after the
Closing. In the event of the termination by the Surviving Corporation of any
Employees of Company or the Subsidiaries during the first twelve (12) months
following Closing, the Buyer hereby agrees to indemnify and hold those
individuals who were officers or directors of the Company at or prior to the
Closing harmless from and against any claims arising from such terminations,
unless such claims are based upon commitments, representations made or other
actions taken by the Company or such individuals to the terminated Employee
prior to Closing and not disclosed by the such individuals to the Buyer (but for
this purpose, the Company's severance policy heretofore provided to the Buyer
shall not be deemed to be a commitment, representation or other action taken by
the such individuals). Except for accrued vacation and sick time, no other
employee benefit plan liability of the Company or its Subsidiaries is being
assumed by the Buyer.

         6.6 Insurance. Prior to the Closing, the Company shall use commercially
reasonable efforts to obtain tail coverages for its Officers and Directors
liability policy(s) and for its employment practices policies, each as described
on Schedule 6.6



                                      -33-
<PAGE>   40

(the "Tail Coverages"), with the cost thereof to be borne by the Company and
paid or accrued on the Closing Balance Sheet. After the Closing, the Buyer shall
cause the Surviving Corporation not to cancel or amend the Tail Coverages and to
maintain such insurance at least equivalent in coverage amount, quality of
carrier, and covered claims to that for the Company and/or the Subsidiaries or
their successors as is customarily maintained by companies of the same size in
the propane industry for so long as the provisions of Section 9.2 remain
effective as to the type of liability covered by such insurance.

         6.7 Audited Financial Statements. The Buyer intends to prepare audited
financial statements of the Company for periods prior to the Closing. The Buyer
acknowledges that the preparation of such financial statements is solely the
responsibility of the Buyer and shall be at its sole cost and expense.

         6.8 Post-Closing Tax Matters. Buyer acknowledges and agrees that the
Shareholder Representative shall have the exclusive power and authority (i) at
the expense of the Company, to cause the income tax returns for the last
separate taxable year of the Company ending as a result of the consummation of
the transactions contemplated by this Agreement and the immediate liquidation of
the Surviving Corporation through merger to be prepared and filed in accordance
with historic practices and procedures of the Company and applicable law
(provided, however, the Shareholder Representative shall follow the instructions
of Buyer with respect to determining and reporting the treatment and effects of
such liquidation through merger, which shall be solely the responsibility of the
Buyer), (ii) to control the conduct of the Surviving Corporation in respect of
any tax audit or examination and any administrative appeal or litigation
relating thereto, to the extent it relates to any Taxes required to be paid by
the Company for periods ending on or before the Closing Date if such Taxes are
payable (the costs of any such audit or examination shall be borne by the
Surviving Corporation until the issuance of a notice of deficiency, whereas the
costs of any administrative appeal or litigation after the issuance of a notice
of deficiency shall be borne by the Company Shareholders), (iii) subject to the
provisions of this Section to determine whether and to what extent to amend any
Tax return filed before the Closing Date or which is described in the
immediately preceding clause (i), and (iv) whether and to what extent the
Surviving Corporation shall extend or waive any statute of limitations for the
assessment of any Tax required to be paid by the Company for periods ending on
or before the Closing Date if such Tax is payable. Buyer shall have the right to
participate in any such amendment, extension of limitation, tax audit,
examination, appeal or litigation (collectively, a "tax proceeding") at Buyer's
sole expense, and, notwithstanding the immediately preceding sentence, to
jointly control with the Shareholder Representative any such tax proceeding if
(i) the amount claimed by the taxing authority in a notice of deficiency would
result in a liability to the Surviving Corporation or its Subsidiaries that
exceeds the amount of Damages for which the Company Shareholders are liable
pursuant to Article IX or (ii) the proposed tax proceeding would reasonably
result in a material tax



                                      -34-
<PAGE>   41

or expense to any Controlled Entity. In no event shall the Shareholder
Representative settle any such tax proceeding without Buyer's consent if such
settlement would materially adversely affect the Surviving Corporation or any of
its subsidiaries (or a Buyer Affiliate that is a successor in interest to the
Surviving Corporation or any of its subsidiaries) with respect to any period
after the Closing or result in any material liability on the part of the
Surviving Corporation or such successor in interest which is not required to be
paid by the Company Shareholders pursuant to Section 9.2 of this Agreement or
pursuant to the Escrow Agreement or (ii) any Controlled Entity or a Buyer
Affiliate that is the successor in interest of such Controlled Entity.

                  For purposes of this Section 6.8, a material effect shall be
deemed to be an expense, charge, loss or adverse change in an amount in excess
of the amount in the Escrow Fund as of the date of determination of such
expense, charge, loss or adverse change. The Buyer shall have the right to file
amended income tax returns for the Company or its Subsidiaries for any period,
provided that the result of such amended return would not affect the liability
of the Shareholders (i) for Damages hereunder or for any other damages, costs,
expenses or obligations of any nature or (ii) for income taxes or other Taxes
for any of the Controlled Entities, in which event the Shareholder
Representative and the Buyer (or a Buyer Affiliate that is a successor in
interest to the Company) or any of its Subsidiaries must consent in writing to
and Shareholder Representative shall jointly control with the Buyer (or its
Affiliate successor in interest to the Company and its Subsidiaries) the filing
of any such amended income tax return and all matters relating thereto.

                  The Buyer (or a Buyer Affiliate that is a successor in
interest to the Company) shall afford the Shareholder Representative a
reasonable opportunity to review any proposed form of income Tax Return of the
Company (such as a state income tax return) for any period that begins before
and ends after the Closing Date and shall not file any such Tax Return without
the prior written consent of the Shareholder Representative, which consent shall
not be unreasonably withheld. The Shareholder Representative and the Buyer (or a
Buyer Affiliate that is a successor in interest to the Company) shall jointly
control any tax proceeding with respect to any such income tax return.

         6.9 Environmental Site Assessment. The Buyer may conduct environmental
site assessments after the Closing with respect to the Real Estate and
properties covered by the Real Estate Leases. The Buyer acknowledges that the
conducting of such environmental site assessments is solely the responsibility
of the Buyer and shall be at its sole cost and expense. For a period of three
(3) years from the Closing or such longer period, if any, as any claims remain
outstanding that have been made by Buyer or any of the Buyer Indemnitees with
respect to any alleged breach of the representations and warranties in Section
3.23 or of any other representations, warranties or covenants relating to
environmental matters, the Buyer agrees to provide the Shareholder
Representative with at least ten (10) business days notice prior to



                                      -35-
<PAGE>   42

conducting any such environmental site assessment and to permit the Shareholder
Representative and/or an independent environmental consultant retained by the
Shareholder Representative to have reasonable access to such Real Estate and
properties and to have access (on a current basis) to the extent reasonably
practicable to data and information collected and conclusions reached by the
environmental consultants or other environmental employees or representatives
utilized by Buyer for such environmental site assessments ("Buyer's
Environmental Consultants"), including, without limitation, raw data, boring
logs, splits of all samples taken and laboratory results obtained by Buyer's
Environmental Consultants, and to contact Buyer's Environmental Consultants
directly. Buyer shall promptly provide to the Shareholder Representative copies
of all Phase I reports and other environmental reports prepared by Buyer's
Environmental Consultants.

                                  ARTICLE VIII
               CONDITIONS PRECEDENT TO OBLIGATIONS OF THE COMPANY

         9.1 Survival of Representations and Warranties. The representations and
warranties of the Company and the Buyer contained in this Agreement shall

         9.2 Indemnification. Each Shareholder and the Company (but only until
the Effective Time) (collectively, the "Company Indemnifying Parties"), agree
severally, but not jointly, to indemnify and hold harmless the Buyer and its

employees and their respective successors and permitted assigns (collectively,
the "Buyer Indemnified Parties") against and in respect of any and all claims,
demands, losses, damages, costs and reasonable expenses, including reasonable
legal fees and expenses, other than any special, incidental consequential,
exemplary or punitive damages or damages relating to lost profits (collectively,
Damages") incurred by any Buyer Indemnified Party by reason of or arising out

<PAGE>   47

                           (ii) any failure by the Buyer to perform or otherwise
         fulfill or comply with any covenant contained in this Agreement.

         9.4 Defense of Third Party Claims. If either Party hereto or a Buyer
Indemnified Party or a Company Indemnified Party (each an "Indemnitee") receives
notice or otherwise obtains knowledge of any third party claim or other matter
with respect to which the other Party hereto (the "Indemnifying Party") may
become obligated to hold harmless or indemnify the Indemnitee hereunder, then
the Indemnitee shall promptly deliver to the Indemnifying Party a written notice
describing such matter in reasonable detail and specifying the estimated amount
of the Damages that may be incurred by the Indemnitee in connection therewith.
The Indemnifying Party shall have the right, at its option, to assume the
defense of such matter at its own expense and with its own counsel, provided
such counsel is reasonably satisfactory to the Indemnitee. If the Indemnifying
Party elects to assume the defense of such matter, (i) notwithstanding anything
to the contrary contained herein, the Indemnifying Party shall not be required
to pay or otherwise indemnify the Indemnitee against any attorneys' fees or
other expenses incurred on behalf of the Indemnitee in connection with such
matter following the Indemnifying Party's election to assume the defense of such
matter, (ii) the Indemnitee shall fully cooperate as reasonably requested by the
Indemnifying Party in the defense or settlement of such matter, (iii) the
Indemnifying Party shall keep the Indemnitee informed of all material
developments and events relating to such matter and (iv) the Indemnitee shall
have the right to participate, at its own expense, in the defense of such
matter. In no event will the Indemnifying Party be liable for any settlement or
admission of liability with respect to such matter without its prior written
consent.

         9.5 Liability of the Company Indemnifying Parties.

                  (a) The Company Indemnifying Parties shall have no liability
(for indemnification or otherwise) under or relating to this Agreement or the
transaction contemplated hereby until the total of all Damages with respect
thereto exceeds one percent (1%) of the difference between (i) the Purchase
Price and (ii) the Specified Cash Amount (the "Deductible Amount") and then only
for the amount by which such Damages exceed the Deductible Amount.

                  (b) Except for Environmental Liabilities governed by Section
9.5(c) hereof, the cumulative liability of the Company Indemnifying Parties
under this Agreement and the Schedules, certificates and documents delivered
pursuant hereto or in connection herewith, shall in no event exceed, and the
total amount of the indemnification payments that the Company Indemnifying
Parties can be required to make under or relating to this Agreement, shall be
limited in the aggregate to, a maximum of twenty percent (20%) of the difference
between (i) the Purchase Price and (ii) the Specified Cash Amount, and except as
provided in Section 9.5(c), the Buyer Indemnified Parties' sole recourse under
this Agreement or the Escrow



                                      -41-
<PAGE>   48

Agreement or with respect to the transactions contemplated hereby and thereby
shall be against the Escrow Amount. Each Shareholder's liability to indemnify
the Buyer Indemnified Parties for Damages pursuant to the terms of Section 9.2
hereof shall be limited to such Shareholder's Proportionate Share of the
Damages. For purposes of this Section 9.5, a Shareholder's Proportionate Share
of Damages shall be the percentage of the Damages that is equal to the
percentage of the Purchase Price that such Shareholder is entitled to receive
under this Agreement.

                  (c) The cumulative liability of the Company Indemnifying
Parties for breaches of Section 3.23 of this Agreement and Schedule 3.23
delivered pursuant thereto (the "Environmental Liabilities") shall in no event
exceed, and the total amount of indemnification payments that the Company
Indemnifying Parties can be required to make under or relating to this Agreement
with respect to Environmental Liabilities shall be limited in the aggregate to a
maximum of the difference between (i) the Purchase Price and (ii) the Specified
Cash Amount, less any amounts paid or required to be paid by the Company
Indemnifying Parties pursuant to Section 9.2 other than on account of breaches
of Section 3.23 (the "Environmental Maximum"), so that in no event will the
cumulative liability of the Company Indemnifying Parties under this Agreement
and the Schedules, certificates and documents delivered pursuant hereto or in
connection herewith exceed, and the total amount of the indemnification payments
that the Company Indemnifying Parties can be required to make under or relating
to this Agreement with respect to any and all matters (including Environmental
Liabilities) shall be limited in the aggregate to the difference between (i) the
Purchase Price, and (ii) the Specified Cash Amount. Any Environmental
Liabilities shall be satisfied first by the Surviving Corporation's insurance if
any. To the extent any Environmental Liability is not satisfied by the Surviving
Corporation's insurance, the recourse of the Buyer Indemnified parties shall
then be against the Escrow Fund, with the Company Indemnifying Parties being
liable only for the amount, up to the Environmental Maximum, not satisfied by
the Surviving Corporation's insurance and/or the Escrow Fund.

         9.6 Liability of Buyer. The Buyer shall have no liability (for
indemnification or otherwise) under or relating to this Agreement or the
transaction contemplated hereby until the total of all Damages with respect
thereto exceeds the Deductible Amount and then only for the amount by which such
Damages exceed the Deductible Amount. The Buyer's cumulative liability under
this Agreement and the Schedules, certificates and documents delivered pursuant
hereto or in connection herewith shall in no event exceed, and the total amount
of the indemnification payments that the Buyer can be required to make hereunder
shall be limited in the aggregate to a maximum of twenty percent (20%) of the
difference between (i) the Purchase Price, and (ii) the Specified Cash Amount.

         9.7 Exclusivity. The right of each Party hereto and its other
Indemnitees to demand and receive indemnification payments pursuant to this
Article IX shall be the



                                      -42-
<PAGE>   49

sole and exclusive remedy exercisable by such Party or Indemnitee with respect
to any of the matters described in Sections 9.2 or 9.3 or with respect to any
other claims arising out of or relating to this Agreement or any of the
transactions contemplated hereby or any of the Related Transactions.

         9.8 Reduction for Reserves. The amount of any claim by the Buyer
Indemnified Parties under Section 9.2(i) shall be reduced by the amount of any
reserves provided for in the Closing Financial Statements; provided that the
claim relates to the category or class for which the reserve was established.

         9.9 Reduction for Insurance Proceeds and Tax Savings. The amount of any
Damages claimed by any Indemnitee hereunder shall be reduced to the extent of
(i) any insurance proceeds, indemnification or other reimbursement or payment
recoverable by the Buyer or the Indemnitee in connection with such Damages or
the claim giving rise thereto; and (ii) any Tax savings or benefits realized or
to be realized by the Buyer or by any Indemnitee in connection with such Damages
or the claim giving rise thereto (it being acknowledged by the Parties that
there may be no such Tax savings or benefits).

         9.10 Subrogation. Each Indemnifying Party under this Article IX shall
be subrogated to any and all defenses, claims or setoffs which the Indemnitee
asserted or could have asserted with respect to any third party claim as to
which the Indemnifying Party is required to provide indemnification pursuant to
this Article IX. The Indemnitee shall, and (in the event the Buyer is an
Indemnitee) shall cause the Shareholder Representative to, execute and deliver
to the Indemnifying Party such documents as may be necessary or appropriate to
establish by way of subrogation the ability and right of the Indemnifying Party
to assert such defenses, claims or setoffs. In no event shall any Party hereto
be liable for special, incidental, consequential, exemplary or punitive damages
or damages relating to lost profits, nor shall there be any double counting of
any item of Damage.

                                   ARTICLE X
                           TERMINATION BY THE PARTIES

         10.1 Events of Termination. Without prejudice to other remedies which

                  (a) by mutual written consent of the Parties hereto;

                  (b) at the election of the Shareholder Representative, if any

<PAGE>   50

                  (c) at the election of the Buyer, if any one or more of the

Agreement shall be terminated without further action by any Party. Upon
termination of this Agreement:

                  (a) The Buyer shall return to the Company all documents and
copies and other materials received from the Company relating to the
transactions contemplated hereby, the Company, the Subsidiaries, or the Business
of the Company or the Subsidiaries, whether obtained before or after the
execution hereof; and

                  (b) All confidential information received by the Buyer shall
be treated in accordance with the Confidentiality Agreement, which shall remain
in full force and effect notwithstanding the termination of this Agreement.

         10.3 Effect of Termination. If this Agreement is terminated and the
transactions contemplated hereby are abandoned, this Agreement shall become null
and void and of no further force and effect, except for this Article X, Article
XI and the obligation of the Buyer to keep confidential certain information
concerning the Company and the Business as described in Section 12.3 and as
provided in the Confidentiality Agreement. Nothing in this Article X shall be
deemed to release any Party from any liability for any breach by such Party of
the terms and provisions of this Agreement or to impair the right of any Party
to compel specific performance by another Party of its obligations hereunder.

                                   ARTICLE XI
                           SHAREHOLDER REPRESENTATIVE

         11.1 Appointment of Shareholder Representative. The Company and the
Company Shareholders, by virtue of the adoption of this Agreement, irrevocably
appoint Gregory Bunting to act as their sole and exclusive representative (the
"Shareholder Representative") to receive installments of the Escrow Amount and
the A/R Reserve Escrow amount on the Company Shareholders' behalf and to make
all decisions and determinations under or relating hereto on their behalf that
the Shareholder Representative may deem necessary or appropriate. Without
limiting the generality of the immediately preceding sentence, the Shareholder
Representative may, in his good faith discretion, object to, settle or
compromise any Indemnity Claim made under this Agreement or any dispute with
respect to the Escrow Fund or the A/R Reserve Escrow or any installment thereof,
and authorize payments to be made with respect thereto. All actions taken by the
Shareholder Representative hereunder shall be binding upon the Company
Shareholders and their successors as if expressly confirmed and ratified in
writing by each of them, and no Company Shareholder shall



                                      -44-
<PAGE>   51

have the right to object, dissent, protest or otherwise contest the same. All
actions, decisions and instructions of the Shareholder Representative shall be
conclusive and binding upon all of the Company Shareholders and no Company
Shareholders shall have any cause of action against the Shareholder
Representative for any action taken, decision made or instruction given by such
Shareholder Representative under or with respect to this Agreement, except for
gross negligence or willful misconduct by such Shareholder Representative.

         11.2 Shareholder Representative Escrow. As provided in Section 9 of the
Escrow Agreement, at the Closing a sum equal to one percent (1%) of the
Estimated Purchase Price out of the portion of the Purchase Price to be paid by
the Buyer at Closing shall be placed into an interest-bearing escrow account
(the "Shareholder Representative Escrow") established by the Shareholder
Representative. The Shareholder Representative shall have the right to withdraw
funds from the Shareholder Representative Escrow to cover "Expenses" (as defined
in the Escrow Agreement), and the establishment of the Shareholder
Representative Escrow and withdrawals therefrom pursuant to the provisions of
Section 9 of the Escrow Agreement are hereby specifically authorized.

         11.3 Successor Shareholder Representative. The Shareholder
Representative, or any successor to him hereafter appointed, may resign and
shall be discharged of his duties hereunder and under the Escrow Agreement upon
the appointment of a successor Shareholder Representative as hereinafter
provided. In case of the resignation or the death or inability to act of the
Shareholder Representative appointed by the Company, or any of his successors, a
successor shall be named by the Company. Each such successor Shareholder
Representative shall have the power, authority, rights and privileges hereby
conferred upon the original Shareholder Representative succeeded by him, and the
term "Shareholder Representative" as used herein and in the Escrow Agreement
shall be deemed to include a successor Shareholder Representative.

         12.1 Amendments and Waiver. This Agreement may be amended at any time
prior to the Effective Time, whether before or after the adoption of this
Agreement by the Company's Shareholders; provided that after adoption of this
Agreement by the Company's Shareholders no amendment shall be made which by law

approval. No amendment, waiver or consent with respect to any provision of this
Agreement shall in any event be effective, unless the same shall be in writing
and signed by all Parties hereto, and then such amendment, waiver or consent
shall be effective only in the specific instance and for the specific purpose

Party's right at a later time to enforce the same. No waiver by any Party of the
breach of any term or covenant contained in this Agreement in any one or more
instances shall be deemed to be, or construed as, a further or continuing waiver
of any such breach, or a waiver of the breach of any other term or covenant
contained in this Agreement.

                  Any Party may change its address for receiving notice by
written notice given to the others named above.

         12.3 Confidentiality. All information given by any Party hereto to any
other Party shall be considered confidential and shall be used only for the
purposes intended. The provisions of the Confidentiality Agreement are
incorporated herein by reference and shall continue to apply for the benefit of
the Company and the Subsidiaries as if entirely set forth herein, unless and
until the Closing occurs. The provisions of this Section 12.3 and of the
Confidentiality Agreement referenced in the preceding sentence shall remain in
force and effect notwithstanding any termination of this Agreement under Article
X hereof.

         12.4 No Public Announcement. Neither the Buyer nor the Company nor any
of the affiliates of either of them shall make any public announcement or
disclosure concerning the transactions contemplated by this Agreement without
the prior written approval of the other Party, except as required by law or as
permitted by this Section 12.4. If any Party or any of its affiliates determines
upon advice of counsel that a public announcement or disclosure is required by
applicable securities laws or regulations or stock exchange regulations, such
Party may make the announcement or disclosure provided it first consults with
the other Party hereto so that the Parties may coordinate concurrent public
announcements and/or other disclosures and review the proposed text of such
announcement. In addition, the Parties shall jointly prepare press releases
disclosing the sale of the Company to the Buyer, for release immediately upon
the execution of this Agreement and immediately after the Closing.

         12.5 Expenses. Except as otherwise expressly provided herein, and
except to the extent the same are paid by the Company from its cash or cash
equivalents or are accrued on the Closing Balance Sheet, the Company and the
Buyer shall bear their own costs and expenses in connection with the
transactions contemplated hereby. Should the Buyer desire to liquidate the
Company after the Closing, whether through a merger or otherwise, the Buyer may
do so at its own expense. The provisions of this Section 12.5 shall survive any
termination of this Agreement.

         12.6 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and assigns; provided, however, that no Party shall assign any rights or
delegate any of its obligations created under this Agreement prior to Closing
without the prior written consent of the other Parties. This Agreement does not
create any rights, claims or benefits inuring to any Person that is not a party
hereto nor create or establish any third-party beneficiary hereto.

         12.7 Entire Transaction. This Agreement and the documents referred to
herein contain the entire understanding among the Parties with respect to the
transactions contemplated hereby and supersede all other agreements,
understandings



                                      -47-
<PAGE>   54

and undertakings among the Parties regarding the subject matter hereof. All
Schedules hereto are hereby incorporated herein by reference and made a part of
this Agreement.

         12.8 Severability. In the event that any provision of this Agreement
shall be held to be invalid or unenforceable by any court of competent
jurisdiction, such holding shall in no way effect, invalidate or render
unenforceable any other provision hereof.

         12.9 Governing Law and Jurisdiction. This Agreement, the Agreement of
Merger, the Escrow Agreement and the other documents executed pursuant hereto or
in connection herewith (the "Related Agreements") shall be governed by and
construed in accordance with the domestic laws of the State of California
without giving effect to any choice or conflict of law provision or rule
(whether of the State of California or any other jurisdiction) that would cause
the application of the laws of any jurisdiction other than the State of
California. Subject to the provisions of Section 12.10, and without limiting
such provisions in any way, each of the Parties submits to the jurisdiction of
the United States District Court for the Northern District of California,
sitting in San Francisco, California, or the Superior Court of the State of
California for the County of San Francisco, in any action or proceeding arising
out of or relating to this Agreement or the Related Agreements and agrees that
all claims in respect of any such action or proceeding may be heard and
determined in any such court. Subject to the provisions of Section 12.10, and
without limiting such provisions in any way, each Party also agrees not to bring
any action or proceeding arising out of or relating to this Agreement or the
Related Agreements in any other court or tribunal. Each of the Parties waives
any defense of inconvenient forum to the maintenance of any such action or
proceeding so brought. Each Party agrees to frame any complaint brought in any
such action or proceeding to support federal court jurisdiction if grounds for
federal jurisdiction exist, and further agrees that any of the other Parties may
require such Party to dismiss any state law case where a federal court would
have jurisdiction over the subject matter.

         12.10 Dispute Resolution. Except for disputes as to the Adjustment
Amount, which shall be resolved in the manner provided in Section 1.8, all
disputes arising under or relating to this Agreement or the Related Agreements
shall be settled by final and binding arbitration in San Francisco, California,
by a mutually agreeable retired judge in the San Francisco office of the
Judicial Arbitration and Mediation Service (JAMS) selected pursuant to the
procedures set forth below (the "Arbitrator"). Judgment upon the award rendered
by the Arbitrator may be entered only in the United States District Court for
the Northern District of California or the Superior Court of San Francisco
County, California, and such judgment may be enforced in any court having
jurisdiction thereof. The arbitration shall proceed in accordance with the laws
of the State of California, except as otherwise expressly provided herein. Any
Party requesting arbitration shall serve a written demand for arbitration on the
other Parties in the manner described in this Section. The demand shall set
forth in reasonable



                                      -48-
<PAGE>   55

detail a statement of the nature of the dispute, the amount involved and the
remedies sought. No later than thirty (30) calendar days after a demand for
arbitration is served, the Parties shall jointly agree upon a retired judge to
serve as Arbitrator. In the event that the Parties do not agree within said
30-day period on the selection of a retired judge, then no later than ten (10)
days after the end of such 30-day period, the San Francisco office of JAMS shall
select a retired judge located in its San Francisco office to become the
Arbitrator and to resolve the dispute.

                  No later than ten (10) calendar days after appointment of the
Arbitrator pursuant to the terms of this Section 12.10, the Parties shall
jointly prepare and submit to the Arbitrator a set of rules for the arbitration.
In the event that the Parties do not agree on the rules for the arbitration, the
Arbitrator shall establish the rules and procedures for any such proceedings
which, unless the Parties otherwise agree, shall be concluded within sixty (60)
days after such submission. The fees and expenses of such arbitration (including
reasonable attorneys' fees) or any action to enforce an arbitration award shall
be paid by the Party that does not prevail in such arbitration as determined by
the Arbitrator. The Arbitrator shall not have the power to amend this Agreement
in any respect, nor shall the Arbitrator have the right to award punitive
damages. The Parties agree that all facts and information relating to any
arbitration arising under this Agreement or the Related Agreements shall be kept
confidential to the extent possible. The Parties agree that all documents filed
with any court in connection with the resolution of any dispute hereunder shall
be filed under seal. The decision in the arbitration proceeding shall be final
and non-appealable.

                  Any action to compel arbitration or to preserve the
jurisdiction of any arbitrator by obtaining interim relief pending arbitration
shall be brought in the United States District Court for the Northern District
of California or the Superior Court of San Francisco County, California.

         12.11 Headings. The headings in this Agreement are for reference only
and shall not affect the interpretation of this Agreement.

         12.12 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original and all of which
together constitute one and the same instrument.

         12.13 Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement and the Related Agreements. In the
event an ambiguity or question of intent or interpretation arises, this
Agreement and the Related Agreements shall be construed as if drafted jointly by
the Parties and no presumption or burden of proof shall arise favoring or
disfavoring any Party by virtue of the authorship of any of the provisions of
this Agreement or the Related Agreements. Any reference to any federal, state,
local or foreign statute or law shall be deemed also to



                                      -49-
<PAGE>   56

refer to all rules and regulations promulgated thereunder, unless the context
requires otherwise. The word "including" shall mean "including without
limitation."

         12.14 Further Assurances. Subject to the terms and conditions herein
provided, each of the Parties hereto agrees to use its reasonable commercial
efforts to take, or cause to be taken, all action and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated by
this Agreement.

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT (the "Agreement") is made and entered into as of
____________, 2001 (the "Closing Date"), by and among Gregory S. Bunting (the
"Shareholder Representative"), Heritage Holdings, Inc., a Delaware corporation
(the "Buyer"), and _____________________, as escrow agent ("Escrow Agent").

         Buyer and Shareholder Representative are entering into this Agreement
pursuant to the terms of that certain Agreement and Plan of Merger dated
_______, 2001 entered into by and among Buyer, the Company, the Majority
Shareholders and the Transitory Subsidiary (the "Merger Agreement"). Capitalized
terms used in this Agreement without definition shall have the respective
meanings given to them in the Merger Agreement.

The parties, intending to be legally bound, hereby agree as follows:

1.       Establishment of Escrow.

         (a) Buyer is depositing with Escrow Agent (i) an amount equal to
$_______________ in immediately available funds, and (ii) an amount equal to
$_______________ in immediately available funds (the "A/R Reserve Escrow") to be
placed in a sub-account and be available solely to satisfy the Accounts
Receivable Deficiency pursuant to Section 1.11 of the Merger Agreement. (Such
amounts, as increased by any earnings thereon and as reduced by any
disbursements or losses on investments, are referred to herein as the "Escrow
Fund"). Buyer is also depositing into a sub-account of the Escrow Fund with the
Escrow Agent an amount equal to $_______________ in immediately available funds
representing the "Shareholder Representative Escrow" as described herein and in
the Merger Agreement, to be available only to the Shareholder Representative.
Escrow Agent acknowledges receipt of all of the foregoing amounts.

         (b) Escrow Agent hereby agrees to act as escrow agent and to hold,
safeguard and disburse the Escrow Fund pursuant to the terms and conditions
hereof.

2.       Investment of Funds.

         Except as Buyer and the Shareholder Representative may from time to
time jointly instruct Escrow Agent in writing, the Escrow Fund shall be invested
from time to time, to the extent possible, in United States Treasury Bills
having a time remaining until maturity of 90 days or less and repurchase
obligations secured by such United States Treasury Bills, with any remainder
being deposited and maintained in a money market deposit account with Escrow
Agent, until disbursement of the entire Escrow



                                      B-1
<PAGE>   66

Fund. Escrow Agent is authorized to liquidate in accordance with its customary
procedures any portion of the Escrow Fund consisting of investments to provide
for payments required to be made under this Agreement.

3.       Damages.

         If after Buyer has given a Notice of Damages (as defined in Section 4
of this Agreement) to the Shareholder Representative and Escrow Agent, Damages
are finally determined under Section 4 of this Agreement to be owing to Buyer,
Escrow Agent shall pay to Buyer the dollar amount of such Damages from (and only
to the extent of) the Escrow Fund (other than the portion of the Escrow Fund
constituting the A/R Reserve Escrow, which can only be used in the manner
provided in Section 6 herein) based upon joint written instructions from Buyer
and the Shareholder Representative or a final non-appealable arbitration award
resulting from arbitration in accordance with Section 12.10 of the Merger
Agreement. Escrow Agent shall not inquire into or consider whether the Damages
comply with the requirements of the Merger Agreement.

4.       Certification of Damages; Payment.

         (a) If Buyer is of the opinion that any Damages have or will or may
occur, Buyer shall promptly so notify the Shareholder Representative and the
Escrow Agent in writing, and each such notice (a "Notice of Damages") shall
specify in reasonable detail: (i) an estimate, if practicable, of the amount of
Damages (taking into account the Deductible Amount, the reduction for insurance
proceeds and Tax savings, and the other limitations in Section 9 of the Merger
Agreement), and (ii) the circumstances of such asserted Damages.

         (b) If the Shareholder Representative agrees in writing within 30 days
after receipt of a Notice of Damages that payment is owed under this Section 4
with respect to some or all of the claimed Damages or amounts set forth in any
such Notice of Damages, or if the Shareholder Representative fails to dispute
some or all of the claimed Damages or amounts set forth in such Notice of
Damages by furnishing written notice of such dispute to Buyer and the Escrow
Agent within 30 days after receipt of such Notice of Damages, the Damages not
then in dispute shall be deemed finally determined under this Section 4.

         (c) In the event that the Shareholder Representative furnishes timely
written notice to Buyer, as provided in Section 4(b) hereof, of any dispute as
to whether Damages have occurred or as to the amounts set forth in a Notice of
Damages, then all parties affected by such claim shall promptly use their best
efforts to resolve such dispute. To the extent agreement is thereafter reached
in writing by the Shareholder Representative and Buyer as to the amount of any
Damages theretofore in dispute, such Damages, in the amount agreed upon, shall
be deemed finally determined under



                                      B-2
<PAGE>   67

this Section 4 and the Buyer and the Shareholder Representative shall jointly
furnish a copy of such written agreement to the Escrow Agent.

         (d) In the event that the occurrence or amount of the Damages, or any
part thereof, set forth in a Notice of Damages, remains in dispute for more than
60 days following the giving of such notice (or for such longer period as Buyer
and the Shareholder Representative have mutually agreed upon in writing), then
whether Damages have occurred and the amount of the Damages still in dispute and
all matters relating thereto shall be arbitrated and finally determined in
accordance with Section 12.10 of the Merger Agreement. Buyer and the Shareholder
Representative shall furnish to the Escrow Agent a copy of the document
reflecting the final determination of such Damages.

5.       Net Working Capital Adjustment; Cash Adjustment Amount.

         The parties acknowledge that the Escrow Fund may be used as a source of
payment for that amount owing by the Shareholders to Buyer, if any, represented
by the positive difference between the Estimated Purchase Price and the Purchase
Price (the "Purchase Price Adjustment"), pursuant to Sections 1.7 and 1.8 of the
Merger Agreement, to the extent that the Purchase Price Adjustment exceeds the
Net Working Capital Holdback. Upon final determination of the Purchase Price
Adjustment in accordance with Sections 1.7 and 1.8 of the Merger Agreement
together with interest thereon as provided in Section 1.8(b) of the Merger
Agreement, the Shareholder Representative shall have the right to instruct
Escrow Agent in writing (with a copy of such instruction to be provided
concurrently to Buyer) to pay to Buyer from the Escrow Fund an amount equal to
the excess of (i) the Purchase Price Adjustment together with interest thereon
over (ii) the Net Working Capital Holdback, as provided in Section 1.8(b)(i) of
the Merger Agreement, and Escrow Agent shall comply with such instruction.

6.       Accounts Receivable.

         The parties acknowledge that the A/R Reserve Escrow has been placed in
a sub-account of the Escrow as a source of payment for that amount (the
"Accounts Receivable Deficiency") owing by the Shareholders to Buyer, if any,
represented by the difference between the Accounts Receivable of the Company and
its Subsidiaries and the actual collection of such Accounts Receivable at the
expiration of the period ending four (4) months following the Closing, pursuant
to Section 1.11 of the Merger Agreement. Within 25 days after the Shareholder
Representative's receipt of the Buyer's written notice of the Accounts
Receivable Deficiency, the Shareholder Representative shall instruct the Escrow
Agent in writing (with a copy of such instruction to be provided concurrently to
Buyer) to pay Buyer from the A/R Reserve Escrow the amount of the Accounts
Receivable Deficiency together with interest thereon as provided in Section 1.11
of the Merger Agreement, and Escrow Agent shall



                                      B-3
<PAGE>   68

comply with such instruction. In the event that the amount of the A/R Reserve
Escrow exceeds the Accounts Receivable Deficiency, or if there is no Accounts
Receivable Deficiency or Buyer has not provided such written notice to the
Shareholder Representative within five (5) months following the Closing Date,
the Buyer shall instruct the Escrow Agent in writing (with a copy of such
instruction to be provided concurrently to the Shareholder Representative) to
transfer such excess to the Shareholder Representative Escrow and Buyer shall so
instruct the Escrow Agent. The A/R Reserve Escrow shall be used solely to
satisfy any Accounts Receivable Deficiency and Buyer shall have no claim against
the A/R Reserve Escrow for any other purpose or matter.

7.       Termination of Escrow.

         (a) On the date eighteen (18) months from the date of Closing, Escrow
Agent shall pay and distribute fifty percent (50%) of the then existing amount
of the Escrow Fund to the Company Shareholders in the proportions set forth in
Section 8 of this Agreement, subject to Section 7(c) of this Agreement.

         (b) On the date thirty-six (36) months from the date of Closing, Escrow
Agent shall pay and distribute one hundred percent (100%) of the then existing
amount of the Escrow Fund to the Company Shareholders in the proportions set
forth in Section 8 of this Agreement, subject to Section 7(c) of this Agreement.

         (c) In the event Buyer has given a Notice of Damages as provided in
Section 4 of this Agreement, an amount equal to the aggregate dollar amount of
such Damages specified in such notice shall be retained by Escrow Agent in the
Escrow Fund (and the balance paid to the Company Shareholders) until it receives
joint written instructions of Buyer and the Shareholder Representative or a copy
of a final determination with respect to such Damages as a result of arbitration
in accordance with Section 12.10 of the Merger Agreement.

8.       Allocation of Distributions to Company Shareholders.

         All payments and distributions to the Company Shareholders by the
Escrow Agent or the Shareholder Representative pursuant to this Agreement (the
"Distributions") shall be allocated and paid to the holders of the Common Stock
and the Dissenting Shares in proportion to their respective ownership interest
in such consideration.

         Payments to the Shareholders shall be made by the Escrow Agent at the
addresses furnished to the Exchange Agent, provided that payments in respect of
Dissenting Shares shall be made to the Buyer.

9.       Installment Sale; Tax Treatment of Interest.

         The parties hereto acknowledge and agree that the Merger shall be
treated by all parties hereto as an installment sale in accordance with Section
453 of the Internal Revenue Code of 1986, as amended (the "Code"), and all
parties hereto shall make all necessary tax filings relating to the Merger in a
manner that is consistent with an installment sale in accordance with Section
453 of the Code. In particular, without limitation, the parties hereto
acknowledge and agree that Buyer shall be deemed to be the owner of the assets
which comprise the Escrow Fund (including, without limitation, all interest
earned thereon) until such time as said Escrow Fund (or portion thereof) is
distributed to the Company Shareholders in accordance with the terms of this
Agreement. The parties further acknowledge and agree that any interest income
earned with respect to the Escrow Fund shall be treated for all purposes as
taxable income of the Buyer on form 1099-INT. Upon distribution of all or a
portion of the Escrow Fund to the Company Shareholders, an applicable portion of
any such payment shall be treated for income tax purposes as original issue
discount which shall be taxable as interest income to the recipient Company
Shareholder(s) and which shall be reported as interest expense by the Buyer
pursuant to the terms of Section 1274 of the Code.

10.      Duties of Escrow Agent.

         (a) Escrow Agent shall not be liable, except for its own bad faith,
gross negligence or willful misconduct and, except with respect to claims based
upon such bad faith, gross negligence or willful misconduct that are
successfully asserted against Escrow Agent, Company Shareholders and Buyer shall
jointly and severally indemnify and hold harmless Escrow Agent (and any
successor Escrow Agent) from and against any and all losses, liabilities,
claims, actions, damages and expenses, including reasonable attorneys' fees and
disbursements, arising out of and in connection with this Agreement. Without
limiting the foregoing, Escrow Agent shall in no event be liable in connection
with its investment or reinvestment of any cash held by it hereunder in good
faith, in accordance with the terms hereof, including, without limitation, any
liability for any delays (not resulting from its bad faith, gross negligence or
willful misconduct) in the investment or reinvestment of the Escrow Fund, or any
loss of interest incident to any such delays.

         (b) Escrow Agent shall be entitled to rely upon any arbitration award,
order, judgment, certification, demand, notice, instrument or other writing
delivered to it hereunder without being required to determine the authenticity
or the 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 believed by it to be genuine and may assume that the person purporting
to give receipt or advice or make any statement or execute any document in
connection with the provisions hereof has been duly authorized to do so. Escrow
Agent may conclusively presume that the undersigned



                                      B-5
<PAGE>   70

representative of any party hereto which is an entity other than a natural
person has full power and authority to instruct Escrow Agent on behalf of that
party unless written notice to the contrary is delivered to Escrow Agent.

         (c) Escrow Agent may act pursuant to the written advice of counsel with
respect to any matter relating to this Agreement and shall not be liable for any
action taken or omitted by it in good faith in accordance with such advice.

         (d) Escrow Agent does not have any interest in the Escrow Fund
deposited hereunder but is serving as escrow holder only and having only
possession thereof. Any payments of income from this Escrow Fund shall be
subject to withholding regulations then in force with respect to United States
taxes. Upon written request of the Escrow Agent, the parties hereto will provide
Escrow Agent with appropriate Internal Revenue Service Forms W-9 for tax
identification number certification, or non-resident alien certifications. This
Section 10(d) and Section 10(a) of this Agreement shall survive notwithstanding
any termination of this Agreement or the resignation of Escrow Agent.

         (e) Escrow Agent makes no representation as to the validity, value,
genuineness or the collectability of any security or other document or
instrument held by or delivered to it.

         (f) Escrow Agent (and any successor Escrow Agent) may at any time
resign as such by delivering the Escrow Fund to any successor Escrow Agent
jointly designated by the other parties hereto in writing, or to any court of
competent jurisdiction, whereupon Escrow Agent shall be discharged of and from
any and all further obligations arising in connection with this Agreement. The
resignation of Escrow Agent will take effect on the earlier of (a) the
appointment of a successor (including a court of competent jurisdiction) or (b)
the day which is 30 days after the date of delivery of its written notice of
resignation to the other parties hereto. If at that time Escrow Agent has not
received a designation of a successor Escrow Agent, Escrow Agent's sole
responsibility after that time shall be to retain and safeguard the Escrow Fund
until receipt of a designation of successor Escrow Agent or a joint written
disposition instruction by the other parties hereto or a final non-appealable
order of a court of competent jurisdiction.

         (g) In the event of any disagreement between the other parties hereto
resulting in adverse claims or demands being made in connection with the Escrow
Fund or in the event that Escrow Agent is in doubt as to what action it should
take hereunder, Escrow Agent shall be entitled to retain the Escrow Fund until
Escrow Agent shall have received (i) a final non-appealable arbitration award or
order of a court of competent jurisdiction directing delivery of the Escrow Fund
or (ii) a written agreement executed by all other parties hereto directing
delivery of the Escrow Fund, in which event Escrow Agent shall disburse the
Escrow Fund in accordance with such



                                      B-6
<PAGE>   71

order or agreement. Any arbitration award or court order shall be accompanied by
a legal opinion by counsel for the presenting party satisfactory to Escrow Agent
to the effect that such award or order is final and non-appealable. Escrow Agent
shall act on such arbitration award or court order and legal opinion without
further question.

         (h) Buyer and Shareholder Representative (on behalf of the Company
Shareholders and from the Shareholder Representative Escrow) shall each pay one
half (1/2) of the Escrow Agent's compensation for the services to be rendered by
Escrow Agent hereunder.

         (i) No printed or other matter (including, without limitation,
prospectuses, notices, reports and promotional material) that mentions Escrow
Agent's name or the rights, powers, or duties of Escrow Agent shall be issued by
the other parties hereto or on such parties' behalf unless Escrow Agent shall
first have given its specific written consent thereto.

11.      Limited Responsibility.

         This Agreement expressly sets forth all the duties of Escrow Agent with
respect to any and all matters pertinent hereto. Escrow Agent shall not be bound
by the provisions of any agreement among the other parties hereto except this
Agreement.

12.      Shareholder Representative.

         (a) The Company Shareholders have irrevocably appointed Gregory S.
Bunting to act as the sole and exclusive representative (the "Shareholder
Representative") to make all decisions and determinations on behalf of the
Company Shareholders under this Agreement that the Shareholder Representative
may deem necessary or appropriate. Without limiting the generality of the
immediately preceding sentence, the Shareholder Representative may, in his sole
good faith discretion, object to, settle or compromise any Notice of Damages
made by Buyer under this Agreement or any dispute with respect to the final Cash
Amount, the Adjustment Amount, the Purchase Price Adjustment or the Accounts
Receivable Deficiency, and authorize payments to be made with respect thereto.
All action taken by the Shareholder Representative hereunder shall be binding
upon the Company Shareholders and their successors as if expressly confirmed and
ratified in writing by each of them, and no Company Shareholder shall have the
right to object, dissent, protest or otherwise contest the same. All actions,
decisions and instructions of the Shareholder Representative shall be conclusive
and binding upon all of the Company Shareholders and no Company Shareholder
shall have any cause of action against the Shareholder Representative for any
action taken, decision made or instruction given by such Shareholder
Representative under or with respect to this Agreement or the Merger Agreement,
except for gross negligence or willful misconduct by such Shareholder
Representative.



                                      B-7
<PAGE>   72

         (b) The Shareholder Representative will be entitled to reimbursement of
reasonable costs and expenses (including reasonable attorneys' fees and
arbitration costs) incurred by him or her in connection with the performance of
his or her services and functions under or relating to this Agreement and/or the
Merger Agreement (the "Expenses"). At the Closing, a sum equal to one percent
(1%) of the Estimated Purchase Price shall be placed into an interest-bearing
escrow account (the "Shareholder Representative Escrow") established by the
Shareholder Representative from which the Shareholder Representative shall have
the right to withdraw the Expenses, from time to time, in his discretion and
without any consent or approval of Buyer or any other party. When all Escrow
Funds have been disbursed as provided in this Agreement and the Expenses have
been paid, the Shareholder Representative shall disburse any balance remaining
in the Shareholder Representative Escrow as additional Purchase Price to the
Company Shareholders, in the manner set forth in Section 8 of this Agreement;
provided, however, that if the Shareholder Representative believes, in his
discretion, that he may incur additional Expenses subsequent to such time in
connection with any potential claims that may be asserted against the
Shareholder Representative or otherwise, the Shareholder Representative shall
have the right to retain such portion of the remaining balance in the
Shareholder Representative Escrow for such period of time as he deems necessary,
in his discretion, to cover such Expenses. Upon determination by the Shareholder
Representative that no further Expenses will be incurred, the Shareholder
Representative shall thereafter disburse any balance remaining in the
Shareholder Representative Escrow as provided above.

         (c) The Shareholder Representative, or any successor to him hereafter
appointed, may resign and shall be discharged of his duties hereunder upon the
appointment of a successor Shareholder Representative as hereinafter provided.
In case of the resignation or the death or inability to act of the Shareholder
Representative appointed by the Company Shareholders, or any of his successors,
a successor shall be named by the vote of a majority in interest of the Company
Shareholders. Each such successor Shareholder Representative shall have the
power, authority, rights and privileges hereby conferred upon the original
Shareholder Representative succeeded by him, and the term "Shareholder
Representative" as used herein shall be deemed to include a successor
Shareholder Representative.

13.      Notices.

         All notices, requests, demands and other communications hereunder shall
be in writing and shall be personally delivered or sent by facsimile
transmission with confirming copy sent by overnight courier (such as Express
Mail, Federal Express, etc.) and a delivery receipt obtained and addressed to
the intended recipient as follows:
