respect to matters relating to such Chief Executive Officer or which are
required to be certified by the Committee under the Plan or in order to satisfy
the requirements of the performance-based compensation exception under Section
162(m) of the Code and the regulations promulgated thereunder.

4.       ELIGIBILITY

         Incentive Awards may be made only to a Participant who is not paid an

or any successor plan or program, with respect to that Award Period.

5.       INCENTIVE AWARDS; TERMS OF AWARDS; PAYMENT

         5.1. No later than 90 days after the commencement of an Award Period,
the Committee shall, in its sole discretion, establish in writing: (a) an
Incentive Award Percentage for each Participant for the Award Period; (b) the
extent, if any, to which the Award Amount, if and to the extent payable to a
Participant, shall be paid in the form of Common Stock; (c) whether any shares
of Additional Stock shall be issued to the Participant in respect of any shares
of Common Stock issued in full or partial payment of an Award Amount pursuant to
the preceding clause (b); and (d) any other terms and conditions applicable to
the Incentive Award and any shares of Common Stock (including Additional Stock)
that may be issued pursuant to the terms of the Incentive Award. For purposes of

         5.2. As soon as practicable following the end of an Award Period, but
in all events prior to the payment of any Award Amounts, the Committee shall
compute and certify in writing the amount of the Compensation Pool for that
Award Period, and shall determine whether any Performance Conditions established
for that Award Period were satisfied. In performing such computation, the
Committee may rely upon financial statements supplied by the Corporation's
officers, provided that the Committee believes such statements to have been
prepared in accordance with generally accepted accounting principles.

         5.3. As soon as practicable following the Committee's completion of the
actions specified in Section 5.2, the Committee shall (a) certify in writing the
Award Amount and the number of shares of Common Stock (including Additional
Stock), if any, to be paid or issued to each Participant for that Award Period
and (b) authorize the Corporation to pay the Award Amount and issue shares of
Common Stock to each Participant in accordance with the terms and conditions of
the Plan and the applicable Incentive Award.

         5.4. Except to the extent that, pursuant to the terms of Section 5.1
hereof, the terms of an Incentive Award require that all or a portion of an
Award Amount, to the extent paid, be paid in the form of Common Stock, the
Committee may, in its discretion at the time of payment of an Award Amount pay
such Award Amount in the form of cash, Common Stock (valued based on Fair Market
Value) or a combination thereof.

         5.5. In the event that the Committee does not exhaust the full amount
of the Compensation Pool through the payment of Incentive Awards, the Committee
may, in its sole discretion and no later than 90 days after the commencement of
an Award Period, certify in writing that all or a portion of the remaining
Compensation Pool shall be added to the Compensation Pool for the Award Period
then commenced; provided, that the Committee shall not be authorized to direct
any such carryover in an amount that exceeds $3 million; and, provided further,
that the Committee establishes one or more Performance Conditions that must be
achieved during the Award Period in order for such carryover amount to be
available for the payment of Incentive Awards for that Award Period.

         5.6. The Committee may, in its sole discretion, determine not to pay an
Award Amount or not to issue shares of Additional Stock or to reduce an Award
Amount or the number of shares of Additional Stock below the amount or number of
shares payable or issuable under the terms of the Incentive Award without the
consent of a Participant. Unless otherwise determined by the Committee, no Award
Amount or Additional Stock shall be paid or issued to a Participant unless the
Participant is employed by the Corporation or a Subsidiary as of the date of
payment or issuance.

         5.7. Award Amounts payable, and shares of Common Stock issuable,
hereunder shall be subject to applicable federal, state and local withholding
taxes and other applicable withholding in accordance with the Corporation's
payroll practices as in effect from time to time.

         5.8. The Committee, subject to such terms and conditions as it may
determine, and a Participant pursuant to any deferred compensation plan of the
Corporation, shall have the right to defer the payment of an Award Amount or the
receipt of Additional Stock, provided, in either case, that any additional
amounts credited to such deferred amounts or shares will be based either on a
reasonable rate of interest or the actual rate of return of one or more
predetermined investments specified by the Committee or pursuant to the terms of
such deferred compensation plan.

6.       ISSUANCE OF COMMON STOCK

         6.1. Common Stock issued under this Plan shall be subject to such terms
and conditions as may be established by the Committee pursuant to the terms of
an Incentive Award or at the time of issuance, including but not limited to,
terms and conditions that provide for the lapse of transfer restrictions or
forfeiture provisions to be contingent on continued employment.

         6.2. To the extent that, pursuant to the terms of an Incentive Award,
shares of Common Stock are required to be issued to a Participant in full or
partial payment of an Award Amount, the terms of an Incentive Award may provide
for the issuance of additional shares of Common Stock ("Additional Stock") not
in excess of 25% of the number of shares of Common Stock issued to the
Participant in payment of the Award Amount pursuant to the terms of the
Incentive Award (and not pursuant to Section 5.4 hereof).

time without the consent of the Participants.

of the Corporation's shareholders at the first meeting of the Corporation's
shareholders following adoption of the Plan by the Board.

including attorneys' fees, actually and reasonably incurred in connection with
the defense of any action, suit or proceeding, or in connection with any appeal
therein, to which they or any of them may be a party by reason of any action
taken or failure to act under or in connection with the Plan or any Incentive

action, suit or proceeding to the maximum extent permitted by law.

                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT (the "Agreement") is made and entered
into as of July ___, 2001, by and among the parties listed on the signature page
hereto under the heading "Sellers" (collectively, the "Sellers" and each a
"Seller"), and Heritage Holdings, Inc., a Delaware corporation (the "Buyer").
The Sellers and the Buyer are hereinafter collectively referred to herein as the
"Parties" and each as a "Party."

RECITALS

         A. The Sellers are the record and beneficial owners of Eighty-Three
Thousand Two Hundred Three (83,203) shares of the issued and outstanding Common
Stock, with a par value of $1.00 per share (the "Stock"), of PROFLAME, INC., a
Nevada corporation (the "Company"). The Sellers are the record and beneficial
owners of the shares of the Stock listed opposite their respective names on
Exhibit A attached hereto.

         B. The Company is engaged in the business of retail marketing of
propane to residential, commercial, industrial and agricultural customers and
wholesale distribution to dealers that resell propane to residential and
commercial customers (the "Business").

         C. The Buyer desires to purchase from the Sellers, and the Sellers
desire to sell to the Buyer, all, but not less than all, of their shares of
Stock, on the terms and conditions set forth herein.

         D. Defined terms used and not otherwise defined in the body of this
Agreement shall have the respective meanings assigned in the Appendix attached
hereto.

AGREEMENT

         For good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Parties agree as follows:

                                    ARTICLE I
                                 THE TRANSACTION

         1.1 Purchase and Sale of Stock. At the Closing (as hereinafter
defined), the Sellers shall sell, transfer, assign and deliver to the Buyer, and
the Buyer shall purchase, accept and receive from the Sellers, all of the
Sellers' right, title and interest in and to the Stock, free and clear of any
Liens.

                                      -1-
<PAGE>   7

         1.2 Purchase Price. The aggregate purchase price for the Stock shall be
U.S. $19,088,887 (the "Purchase Price"), as adjusted in the manner provided in
Section 1.3. The Purchase Price shall be allocated among the Sellers in
proportion to their respective holdings of Company Stock as shown on Exhibit A
hereto (their "Allocable Shares of Stock").

         1.3 Adjustments to Purchase Price. The Purchase Price 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
Purchase Price shall be adjusted for (x) the difference between U.S. $3,212,180
and the Company's Net Working Capital (as defined on Schedule 1.3) as of the
Closing Date (the "Adjustment Amount"), and (y) the difference between U.S.
$6,443,228 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 1.3 attached
hereto (collectively, the "Accounting Principles").

         1.4 Adjustment Procedure.

                  (a) The Sellers 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 Sellers 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 (60) days
after the Closing Date. If, within thirty (30) days following delivery of the
Closing Financial Statements, the Buyer has not given the Sellers 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 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, 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) each Party will

                                      -2-
<PAGE>   8

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 that Party 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 both Parties by the Accountants, will be made within sixty (60)
days of submission and will be binding and conclusive on the Parties; and (iii)
the Buyer and the Sellers 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 1.5, the Buyer will pay the
difference to the Sellers 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 Sellers 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 pay to
the Sellers 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. Payments to the Sellers shall be made by wire transfer of
immediately available funds and shall be made in the manner and will be
allocated in the proportions described in Section 1.2. Payment to the Buyer
shall be made out of the Escrow Fund (as defined in the Escrow Agreement)
pursuant to the terms of the Escrow Agreement.

         1.5 Payment of the Closing Estimated Purchase Price. Not later than two
(2) business days prior to the Closing Date, the Sellers 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 $3,212,180, then the Purchase Price plus (a) the
         excess of the Estimated Net Working Capital over $3,212,180, and (b)
         the Estimated Benefit Expense Proration, less the Estimated Assumed
         Debt; and

                                      -3-
<PAGE>   9

                           (ii) if the Estimated Net Working Capital is less
         than $3,212,180, then the Purchase Price plus the Estimated Benefit
         Expense Proration, less the excess of $3,212,180 over the Estimated Net
         Working Capital and less the Estimated Assumed Debt.

         1.6 Excluded Assets. Notwithstanding anything to the contrary contained
herein, the following assets (the "Excluded Assets") shall not be sold or
transferred to the Buyer, and ownership of the Excluded Assets shall be
transferred from the Company to the Sellers prior to Closing:

                           (i) furnishings and personal effects of the Sellers
         which may be located at a Company office or facility but which are not
         listed on the Company's Balance Sheet; and

                           (ii) the office equipment, furnishing, and vehicles
         listed on Schedule 1.6.

         1.7 Accounts Receivable.

                  (a) 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 Sellers 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 Company and its
Subsidiaries, or their successors or assigns, to assign to the Sellers 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 Company 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 Sellers at their book value to determine the
         Accounts Receivable Deficiency.

                                      -4-
<PAGE>   10

                  (b) 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 Company or its Subsidiaries, or their successors in interest,
to convert a customer to COD basis after Closing, the first payments received by
the Company 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 Company or its Subsidiaries, or
their successors in interest, by any such customer for products sold by the
Company 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 Company or its Subsidiaries,
or their successors in interest. Buyer agrees to notify Sellers at the time it
causes the Company or its Subsidiaries, or their successors in interest, to
place any customer on a COD basis.

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

                  (d) On or about the date three (3) months after the Closing
Date, Buyer shall provide Sellers 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 Sellers regarding appropriate steps
to be taken to collect unpaid Accounts Receivable.

         Within twenty-five (25) days after Sellers' 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
Accounts Receivable Deficiency, then the Escrow Agent shall promptly transfer
the excess to the Sellers' Representative Escrow and Buyer shall so instruct the
Escrow Agent.

                                   ARTICLE II

         substantial danger of the sale, forfeiture or loss of any material
         asset of the Company and the Subsidiaries necessary for the operation
         of the Business as presently conducted.

in peaceable possession of the property covered by each Personal Property Lease.

each of the following, whether funded or unfunded, qualified or unqualified (all
the following being herein called "Benefit Plans"), maintained or contributed to

(other than routine claims for benefits) pending or, to the Sellers' Knowledge,

such Benefit Plan, and to the Sellers' Knowledge no facts exist that would
likely give rise to any actions, suits or claims (other than routine claims for

                                      -15-
<PAGE>   21

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, respectively) has engaged in any transaction in connection with
any Benefit Plan that violates Section 406 or 407 of ERISA or that could
reasonably be expected to result in the imposition on the Company of a penalty
pursuant to Section 502 of ERISA, damages pursuant to Section 409 of ERISA or a
tax pursuant to Section 4975 of the Code. Each Pension Plan is qualified in form
under Section 401(a) of the Code, the Internal Revenue Service has issued a
favorable determination letter with respect to each Pension Plan, and to the
Sellers' Knowledge no event has occurred that will or would likely give rise to
a disqualification under Section 401(a) of the Code. No Pension Plan is subject

Closing Date; (ii) resolutions shall have been adopted before the Closing Date

Subsidiary, as applicable, have been 100% vested; and (iii) the distribution
process will begin pursuant to the terms of such plan.

                  (d) Prior to the Closing, the Sellers shall have furnished to
the Buyer correct and complete copies of (i) the plan documents and summary plan

or other funding agreements which implement such Benefit Plan, and (v) all
service agreements that affect such Benefit Plan.

         3.18 Licenses and Permits. Schedule 3.18 contains a correct and
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
Sellers' 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 the Company to conduct its business as such business is now
being conducted.

         3.19 Material Contracts. Except for Real Estate Leases, Personal
Property Leases, licenses of Intellectual Property, Benefit Plans and Employment
Contracts (which are set forth on other Schedules hereto), Schedule 3.19 sets
forth a correct and complete list of all instruments, commitments, agreements,
arrangements and understandings in effect as of the date hereof related to the
Business of the Company and each Subsidiary to which the Company or a Subsidiary
is a party or by which any of its assets are subject or bound and meeting any of
the criteria set forth below (the "Material Contracts"):

                  (a) Loan agreements, security agreements and promissory notes;
and

                  (b) Any other contract, commitment, agreement, arrangement or
understanding related to the Business which (i) provides for payment or
performance by either party thereto involving an aggregate annual payment or
performance obligation of $10,000 or more, (ii) is not terminable without
payment or penalty on sixty (60) days (or less) notice, or (iii) is with any
affiliate of the Company or any officers or directors of the Company. Prior to
the Closing Date, correct and complete copies of each Material Contract

provided, however, that the Sellers 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 Sellers' 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 Sellers' Knowledge, by any other
party. There is no Lien on the Company's or any Subsidiary's interest under any
Material Contract.

interest, additions to tax or interest and penalties with respect thereto
(collectively "Taxes" or, individually, a "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).

                  (b) The Company and each of the Subsidiaries has timely filed
all tax returns required to be filed by them through the date hereof, and the
Sellers shall prepare and timely file, in a manner consistent with prior years
and applicable law, all tax returns required to be filed on or before the
Closing Date.

                  (c) Except as set forth in Schedule 3.20, no penalties or
other charges are or will become due with respect to the late filing of any tax
return of the Company or any Subsidiary required to be filed for any period
ending on or before the Closing Date.

                  (d) With respect to all tax returns of the Company and the
Subsidiaries, except as set forth on Schedule 3.20(i), to the Sellers'
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
nor any Subsidiary is a party to, nor is bound by or has any obligation under
any tax sharing, tax indemnification or similar agreement.

                  (f) Neither the Company nor any of the Subsidiaries currently
has a permanent establishment in any foreign country or engages or has
previously engaged in a trade or business in any foreign country. Neither the
Company nor any of the Subsidiaries is a foreign person within the meaning of
Code Section 1445.

         3.21 Product Warranty. To the Sellers' Knowledge, all products
processed, distributed, shipped or sold by the Company or any Subsidiary conform
with all applicable contractual commitments, except where a failure to conform
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.

         3.22 Legal Proceedings. Except as set forth in Schedule 3.22, neither
the Company nor any Subsidiary is engaged in or is a party to or, to Sellers'
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 Sellers nor the Company nor any
Subsidiary has received notice of any investigation threatened by any
Governmental Entity. As of the date hereof, except as set forth in Schedule
3.22, neither the Company nor any Subsidiary is subject to any judgment, order,
writ, injunction, stipulation or decree of any court or any Governmental Entity

substance," or "hazardous waste," as defined therein, petroleum and petroleum
products, natural gas or synthetic gas, special nuclear or by-product material,
as defined by the Atomic Energy Act of 1954, 42 U.S.C.A. Section 3011 et seq.,
and the regulations promulgated thereto and "hazardous chemical," as defined in
29 C.F.R. Part 1910 or otherwise relating to the manufacture, possession,
distribution, use, treatment, storage, disposal, transport or handling of such
material (such laws and regulations being hereinafter referred to as
"Environmental Laws");

                  (b) Neither the Company nor any Subsidiary is and has not in
the past 5 years been, in violation of, or charged with, convicted of, or to
Sellers' Knowledge investigated for any violation of any federal, state or local
Environmental Law or regulation by any court, governmental body or agency with

exists on any portion of the Real Estate, on the real property leased under the
Real Estate Leases, or on any real property previously owned or leased by the
Company or its Subsidiaries ("Previously Owned/Leased Real Property") that would
likely give rise to a material claim that the Company or any Subsidiary is in
violation of any Environmental Laws; and there have been no disposals, releases
of hazardous substances, materials or wastes, or pollutants or contaminants by
the Company or its Subsidiaries or any such third party from, in or under any of

administrative, investigative, or informal) pending or, to the Buyer's
knowledge, threatened that challenges or may have the effect of preventing,
delaying, making illegal, or otherwise interfering with, the consummation of the

unsolicited inquiries in the event (a) the transactions contemplated by this
Agreement have not closed prior to

<PAGE>   32

July 31, 2001, or (b) the Buyer gives written notice to the Sellers (which
notice shall be given by the Buyer immediately upon its knowledge thereof) that
a problem has come to light as a result of the Buyer's due diligence which would
reasonably be expected to result in a failure to close the transactions
contemplated hereby and such problem has not been resolved within two (2)
business days thereof.

         5.6 Covenant Not To Compete. In connection with the sale of Stock by
each Seller hereunder, and without limiting the provisions of the
Non-Competition Agreement, each Seller (other than those Sellers who are party
to the Non-Competition Agreement) agrees to the restrictions contained in this
Section 5.6.

                  (a) Subject to Section 5.6(b), each such Seller agrees that,
for a period of ten (10) years from the Closing Date in the geographical markets
in which the Business of the Company is currently conducted, such Seller will
not, directly or indirectly, alone or in association with any other Person,
engage in activities competitive with the Business of the Company.

                  (b) Notwithstanding Section 5.6(a), the Sellers and their
affiliates may own up to 5% of a class of equity securities of a publicly held
company engaged in the Business of the Company.

                  (c) As a separate and independent covenant, each such Seller
agrees that, for a period of five (5) years from the Closing Date, such Seller
will not, directly or indirectly, for the purpose of engaging in the Business of
the Company, call upon, solicit, advise or otherwise do business with or attempt
to do business with, any customer of the Company or any Subsidiary as of the
Closing Date so as to take away or interfere with such business, or induce or
solicit any employees of the Company, any Subsidiary, or the Buyer to leave the
employ of the Company, any Subsidiary or the Buyer.

                  (d) Each such Seller acknowledges that the failure of such
Seller to comply with the provisions of this Section 5.6 will result in
irreparable and continuing damage to the Buyer and its affiliates for which
there will be no adequate remedy at law and that, in the event of a failure of
such Seller so to comply, the Buyer and its successors and permitted assigns
shall be entitled to injunctive relief and to such other and further relief as
may be proper and necessary to ensure compliance with the provisions of this
Section 5.6.

                  (e) The parties acknowledge that no part of the Purchase Price
is allocable to the covenants set forth in this Section 5.6 for financial
reporting, tax or any other purpose and that the consideration for the
Non-Competition Agreement is separate and apart from this covenant.

obligations of the Company that are properly classified as long-term liabilities
under GAAP ("Long Term Debt"), except to the extent that (i) Buyer advises
Sellers at least thirty (30) business days prior to the Closing that Buyer
wishes to assume such Long Term Debt, and (ii) Sellers are able by the Closing
to receive all necessary third party consents and approvals as to the Long Term
Debt that Buyer wishes to assume. With respect to the Company's and the
Subsidiaries' vehicle leases, the Sellers shall cause the Company to purchase
the vehicles covered by such leases prior to or on the Closing Date and cause
such leases to be canceled, except with respect to the vehicles on-order
described in Schedule 5.7. The amount of any Long Term 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 payable to Sellers at the
Closing. Except as set forth on Schedule 5.7, Sellers will cause the Company and
its Subsidiaries, at or prior to Closing, (i) to pay any indebtedness or account
owed by the Company and the Subsidiaries to the Retained Entities and (ii) to
collect from the Retained Entities all indebtedness and accounts owed to the
Company and the Subsidiaries by the Retained Entities.

         5.8 Financial Statement Review. The Company shall permit the Buyer, at
Buyer's expense, to review the Company's and its Subsidiaries' books and records
during normal business hours and pursuant to procedures reasonably acceptable to
the Parties, for the purpose of permitting Buyer's auditors to confirm their
ability to render an opinion with respect to the Company's consolidated
financial statements as of and for the periods ending on August 31, 1998, August
31, 1999 and August 31, 2000 and to review the Company's interim financial
statements as of and for the period ending February 29, 2000 and February 28,
2001. All information examined and obtained by Buyer's auditors shall be deemed
to be "Confidential Information" for purposes of the Confidentiality Agreement.
The Company shall provide reasonable assistance, cooperation and access to
Company management as reasonably necessary to complete such pre-closing review
and such post-closing audit, including but not limited to providing management
representation letters and arranging for outside legal representation letters
and board of director minute representation letters.

                               COVENANTS OF BUYER

         6.1 [Intentionally deleted].

         6.2 Records and Documents. For seven (7) years following the Closing
Date, the Buyer shall grant to the Sellers and their representatives, at the

                                      -28-
<PAGE>   34

Sellers' written request, and at the Sellers' 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 Sellers' affairs after the Closing, including the
preparation of Tax returns. The Buyer shall notify the Sellers 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 Sellers to control such
audits and any related settlements with respect to periods beginning on or prior
to the Closing Date; provided, that the Sellers are obligated to indemnify the
Buyer under Section 9.2. The Buyer will cause the Company to promptly forward to
the Sellers 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 Sellers
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 continue to employ for a period of at least two (2) 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 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 Sellers)
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

                                      -29-
<PAGE>   35

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 Seller 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
the Sellers harmless for any inadequacy of such notice and for any liabilities
under or relating to the WARN Act. In the event of the termination by the Buyer
of any Employees of Company or the Subsidiaries during the first twelve (12)
months following Closing, the Buyer hereby agrees to indemnify and hold the
Sellers harmless from and against any claims arising from such terminations,
unless such claims are based upon commitments, representations made or other
actions taken by Company to the terminated Employee prior to Closing and not
disclosed by the Sellers 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 Company). 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 (the "Tail Coverages"), with the cost thereof to be borne by
Sellers and paid or accrued on the Closing Balance Sheet. After the Closing, the
Buyer shall cause the Company 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 Sellers, or any of them, are obligated
to provide indemnification for the type of liability covered by such insurance
coverage to the Buyer or any of the Buyer's affiliates or other related Parties
under this Agreement.

         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
Sellers 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 Buyer's purchase and immediate liquidation
of the Company through merger to be prepared and filed in accordance with
historic practices and procedures of the Company and applicable law (provided,
however, the Sellers' 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 Company in respect of any tax audit
or examination and any administrative appeal or litigation relating thereto, to
the extent it relates to any Taxes with respect to which the Sellers have an
obligation to indemnify the Buyer if such Taxes are payable (the costs of any
such audit or examination shall be borne by the Company 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
Sellers), (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 Company shall extend or waive any statute of limitations for
the assessment of any Tax with respect to which the Sellers have an obligation
to indemnify the Buyer 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 Sellers 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 Company or its Subsidiaries that exceeds the amount of Damages for which
Sellers would be obligated to indemnify Buyer pursuant to Article IX or (ii) the
proposed tax proceeding would reasonably result in a material tax or expense to
any Controlled Entity. In no event shall Sellers settle any such tax proceeding
without Buyer's consent if such settlement would materially adversely affect (i)
the Company or any of its Subsidiaries (or a Buyer Affiliate that is a successor
in interest to the Company or any of its Subsidiaries) with respect to any
period after the Closing or result in any material liability on the part of the
Company or such successor in interest for which the Sellers are not obligated to
indemnify Buyer pursuant to Article IX 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
Sellers (i) for Damages hereunder or for any

                                      -31-
<PAGE>   37

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
Sellers 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 Sellers
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 Sellers' 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 Sellers' Representative, which consent shall not be unreasonably withheld.
The Sellers' 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 Sellers with at least ten
(10) business days notice prior to conducting any such environmental site
assessment and to permit Sellers and/or an independent environmental consultant
retained by Sellers 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 Sellers copies of all Phase I reports and other
environmental reports prepared by Buyer's Environmental Consultants.

         certificate or instrument delivered to the Buyer in connection with
         Closing for the period such representation and warranty survives
         hereunder;

                           (ii) any failure of the Sellers to perform or

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

                                      -37-
<PAGE>   43

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 Sellers.

                  (a) The Sellers 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 Sellers' 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 Sellers 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 excluding from such Purchase Price any amounts paid for the
Company's cash and cash equivalents, and except as provided in Section 9.5(c),
the Buyer's and Buyer's other Indemnitees' sole recourse under this Agreement or
the Escrow Agreement or with respect to the transactions contemplated hereby and
thereby shall be against the Escrow Amount. Each Seller's liability to indemnify
the Buyer and Buyer's other Indemnitees for Damages pursuant to the terms of
Section 9.2 hereof shall be limited to each Seller's Proportionate Share of the
Damages. For purposes of this Section 9.5, a Seller's Proportionate Share of
Damages shall be the percentage of the Damages calculated as the quotient, the
numerator of which shall be the Seller's Allocable Share of the Stock and the
denominator of which shall be 83,203.

                  (c) The Sellers' cumulative liability 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 Sellers can be required to make under or
relating to

                                      -38-
<PAGE>   44

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
Sellers 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 Sellers'
cumulative liability 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 Sellers 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,
excluding from such Purchase Price any amounts paid for the Company's cash and
cash equivalents. Any Environmental Liabilities shall be satisfied first by the
Company's insurance if any. To the extent any Environmental Liability is not
satisfied by the Company's insurance, the Buyer's and Buyer's other Indemnitees'
recourse shall then be against the Escrow Fund, with the Sellers being liable
only for the amount, up to the Environmental Maximum, not satisfied by the
Company'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 sole and exclusive remedy exercisable by such Party and
its other Indemnitees 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 for
indemnification 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

                                      -39-
<PAGE>   45

recoverable by the Company 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 Company 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 shall be subrogated to any
and all defenses, claims or setoffs which the Indemnitee or the Company 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 Company 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 Sellers' Representative, if any one

                  (a) The Buyer shall return to the Sellers all documents and
copies and other materials received from the Sellers 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

<PAGE>   46

                  (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
                             SELLERS' REPRESENTATIVE

         11.1 Appointment of Sellers' Representative. Sellers hereby irrevocably
appoint Gregory Bunting to act as their sole and exclusive representative (the
"Sellers' Representative") to make all decisions and determinations on behalf of
the Sellers under this Agreement and under the Escrow Agreement that the
Sellers' Representative may deem necessary or appropriate. The Sellers'
Representative shall have all of the rights, power, authority and exculpation
from liability set forth in Section 9 of the Escrow Agreement, the provisions of
which are incorporated herein. The Sellers specifically authorize the Sellers'
Representative to execute the Escrow Agreement and hereby approve all of the
terms thereof.

         11.2 Sellers' 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 to
Sellers at Closing shall be placed into an interest-bearing escrow account (the
"Sellers' Representative Escrow") established by the Sellers' Representative.
The Sellers' Representative shall have the right to withdraw funds from the
Sellers' Representative Escrow to cover "Expenses" (as defined in the Escrow
Agreement), and Sellers hereby specifically authorize the establishment of the
Sellers' Representative Escrow and withdrawals therefrom pursuant to the
provisions of Section 9 of the Escrow Agreement.

         11.3 Successor Sellers' Representative. The Sellers' 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 Sellers' Representative as hereinafter provided. In case of the
resignation or the death or inability to act of the Sellers' Representative
appointed by Sellers, or any of his successors, a successor shall be named by
the vote of a majority in interest of the

                                      -41-
<PAGE>   47

Sellers. Each such successor Sellers' Representative shall have the power,
authority, rights and privileges hereby conferred upon the original Sellers'
Representative succeeded by him, and the term "Sellers' Representative" as used
herein and in the Escrow Agreement shall be deemed to include a successor
Sellers' Representative.

                                  ARTICLE XII
                               GENERAL PROVISIONS

         12.1 Amendments and Waiver. 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 for which given. The failure of any Party
at any time or times to require performance of any provisions hereof shall in no
manner affect that 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.

         12.2 Notices. All notices, requests, demands and other communications
hereunder shall be in writing and shall be personally delivered or sent by

</Table>

                  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 Sellers, 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 Sellers 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 accrued on the Closing Balance Sheet, each Party to this Agreement shall bear
its own costs and expenses in connection with the transactions contemplated
hereby. Any sales, transfer or other taxes (other than income taxes) or fees
applicable to the conveyance and transfer from the Sellers to the Buyer of the
Stock shall be

                                      -43-
<PAGE>   49

borne by the Buyer. 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 Sellers shall use commercially reasonable efforts to assist in any
such liquidation upon Buyer's reasonable request, but any out-of-pocket expenses
incurred by any Seller in providing such assistance at Buyer's request shall be
promptly reimbursed by Buyer to such Seller. 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 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 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

                                      -44-
<PAGE>   50

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 1.4, 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 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.

                                      -45-
<PAGE>   51

         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 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
"Sellers' Representative"), Heritage Holdings, Inc., a Delaware corporation (the
"Buyer"), and _____________________, as escrow agent ("Escrow Agent").

         Buyer and Sellers' Representative are entering into this Agreement
pursuant to the terms of that certain Stock Purchase Agreement dated _______,
2001 entered into by and among Buyer and Sellers (the "Stock Purchase
Agreement"). Capitalized terms used in this Agreement without definition shall
have the respective meanings given to them in the Stock Purchase 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 1.7 of the Stock Purchase 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 "Sellers' Representative Escrow" as described herein and in the
Stock Purchase Agreement, to be available only to the Sellers' 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 Sellers' 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 ninety (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 Fund. Escrow Agent is authorized
to liquidate in accordance with its customary

                                      B-1
<PAGE>   62

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 Sellers' 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 Sellers' Representative or a final nonappealable arbitration award
resulting from arbitration in accordance with Section 12.10 of the Stock
Purchase Agreement. Escrow Agent shall not inquire into or consider whether the
Damages comply with the requirements of the Stock Purchase 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 Sellers' 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 Stock Purchase
Agreement), and (ii) the circumstances of such asserted Damages.

         (b) If the Sellers' Representative agrees in writing within thirty (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 Sellers' 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 thirty (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 Sellers' 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 Sellers' 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>   63

this Section 4 and the Buyer and the Sellers' 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
sixty (60) days following the giving of such notice (or for such longer period
as Buyer and the Sellers' 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 Stock Purchase Agreement.
Buyer and the Sellers' 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 a portion of the Escrow Fund may be used
as a source of payment for that amount owing by Sellers 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 1.3
and 1.4 of the Stock Purchase 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 1.3 and 1.4 of the
Stock Purchase Agreement together with interest thereon as provided in Section
1.4(b) of the Stock Purchase Agreement, the Sellers' 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 1.4(b)(i) of the Stock Purchase 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 Sellers 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 1.7 of the Stock Purchase Agreement. Within 25 days after the
Sellers' Representative's receipt of the Buyer's written notice of the Accounts
Receivable Deficiency, the Sellers' 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 1.7
of the Stock Purchase Agreement, and Escrow

                                      B-3
<PAGE>   64

Agent shall 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 Sellers' 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 Sellers' Representative) to
transfer such excess to the Sellers' 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 this Escrow Fund to the Sellers 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 months from the date of the Closing, Escrow
Agent shall pay and distribute one hundred percent (100%) of the then existing
amount of the Escrow Fund to the Sellers 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 Sellers) until it receives joint
written instructions of Buyer and the Sellers' 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 Stock Purchase Agreement.

8.       Allocation of Distribution to Sellers.

         All payments and distributions to the Sellers by the Escrow Agent or
the Sellers' Representative pursuant to this Agreement (the "Distributions")
shall be allocated and paid to the Sellers in accordance with their Allocable
Shares of Stock.

9.       Installment Sale; Tax Treatment of Interest.

         The parties hereto acknowledge and agree that the transactions
contemplated by the Stock Purchase Agreement 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 sale of stock in accordance with
Section 453 of the Code. In particular,

                                      B-4
<PAGE>   65

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 Sellers 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 Sellers, 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 Sellers 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, Sellers 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 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.

                                      B-5
<PAGE>   66

         (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 thirty (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 nonappealable 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 order or agreement. Any arbitration award or
court order shall be accompanied by a legal opinion by counsel for the

         (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.      Sellers' Representative.

         (a) Sellers have irrevocably appointed Gregory S. Bunting to act as the
sole and exclusive representative (the "Sellers' Representative") to make all
decisions and determinations on behalf of the Sellers under this Agreement that
the Sellers' Representative may deem necessary or appropriate. Without limiting
the generality of the immediately preceding sentence, the Sellers'
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 Sellers'
Representative hereunder shall be binding upon the Sellers and their successors
as if expressly confirmed and ratified in writing by each of them, and no Seller
shall have the right to object, dissent, protest or otherwise contest the same.
All actions, decisions and instructions of the Sellers' Representative shall be
conclusive and binding upon all of the Sellers and no Seller shall have any
cause of action against the Sellers' Representative for any action taken,
decision made or instruction given by such Sellers' Representative under or with
respect to this Agreement or the Stock Purchase Agreement, except for gross
negligence or willful misconduct by such Sellers' Representative.

         (b) The Sellers' 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
Stock Purchase 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 "Sellers' Representative Escrow")
established by the Sellers' Representative from which the Sellers'
Representative shall have the right to withdraw the Expenses, from time to time,
in his discretion. When all Escrow Funds have been disbursed as provided in this
Agreement and the Expenses have been paid, the Sellers' Representative shall
disburse any balance remaining in the Sellers' Representative Escrow as
additional

                                      B-7

<PAGE>   68

Purchase Price to the Sellers, in the manner set forth in Section 8 of this
Agreement; provided, however, that if the Sellers' 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 Sellers'
Representative or otherwise, the Sellers' Representative shall have the right to
retain such portion of the remaining balance in the Sellers' Representative
Escrow for such period of time as he deems necessary, in his discretion, to
cover such Expenses. Upon determination by the Sellers' Representative that no
further Expenses will be incurred, the Sellers' Representative shall thereafter
disburse any balance remaining in the Sellers' Representative Escrow as provided
above.

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