     jointly by a representative of BUYER and a representative of such SELLER on
     the Closing Date and priced based upon the average cost method for
     inventory regularly employed by such SELLER in its inventory accounting
     practices; provided, however, that no amount shall be paid under this
     Section 3.1(b) for new or used retail customer propane tanks (the "Parts
     and Appliances Inventory");

               (c) Accounts receivable (the "Accounts Receivable") arising from
     the Business of each SELLER and owned by such SELLER as of the Closing Date
     that are actually collected within one hundred eighty (180) days after the

               (d) An amount equal to the sum of the Growth Capital Expenditures
     incurred by all SELLERS on or after August 1, 1999 and prior to the Closing

     as Schedule 3.1(d)), which are hereby approved by BUYER;

     example, customer promotions and deposits for future expenditures) as
     reflected on the books and records of each SELLER as of the Closing Date to
     the extent such expenses have been approved in advance and in writing by
     BUYER to be included for purposes of this Section 3.1(e), including the
     pre-paid expenses incurred to date as set forth in Schedule 3.1(e) attached
     hereto;

               (f) An amount equal to the outstanding balance owed by River

               (g) An amount equal to the amount calculated in this Section
     3.1(g). First, a physical inventory of the number of new (not used) retail
     customer propane tanks owned by each SELLER on the Closing Date usable and
     saleable in the ordinary course of the Business of such SELLER shall be
     taken jointly by a representative of BUYER and a representative of such
     SELLER on the Closing Date. The cost per tank used to value this physical
     inventory will be the most recent net price per tank paid for by such
     SELLER. The total value of physical inventory of new tanks on the Closing
     Date determined above shall be adjusted by the following number "x" to
     arrive at the total
<PAGE>

     amount paid under this Section 3.1(g). The number "x" shall be equal to Net
     Purchases minus Net Sets; where, "Net Purchases" is equal to the number of
     all new (not used) retail customer propane tanks purchased by SELLERS from
     August 1, 1999 to the Closing Date, minus the number of new tanks sold
     during such period, in both cases in the ordinary course of business of
     such SELLER consistent with past practices of such SELLER and consistent
     with industry practices, and "Net Sets" is equal to the number of retail
     customer propane tanks installed by SELLERS from August 1, 1999 to the
     Closing Date, in the ordinary course of business of such SELLER consistent
     with past practices of such SELLER and consistent with industry practices,
     minus the number of used tanks picked up from retail customers during such
     period. If the number of tanks calculated in "x" is negative, then 90% of
     that number "x" shall be added to the value of the physical inventory of
     new tanks on the Closing Date to arrive at the total net dollar amount paid
     for under this Section 3.1(g). If the number of tanks calculated in "x" is
     positive, then 90% of that number "x" shall be deducted from the value of
     the physical inventory of new tanks on the Closing Date to arrive at the
     total net dollar amount paid for under this Section 3.1(g). If the number
     of tanks calculated in "x" is zero, then the actual physical inventory of
     new tanks on Closing Date shall be paid with no adjustments. The value per
     tank to be used in any adjustment for "x" shall be the most recent price
     paid by SELLER for such tanks.

               (h) An amount equal to the number of Net Sets (as defined in
     Section 3.1(g) above) multiplied by the sum of $125, plus an amount equal
     to the actual cost of all new (not used) tanks purchased by SELLERS, minus
     the number of new tanks sold by SELLERS during such period, in both cases
     since August 1, 1999 to the Closing Date. (An itemized calculation of the
     sum payable pursuant to this Section 3.1(h) through July 31, 2000 is set
     forth in Schedule 3.1(h) and is hereby approved by SELLERS and BUYER);

               (i) An amount equal to $1,700 per day for each day between June
     30, 2000 and the Closing Date (the "Operating Loss Adjustment");

               (j) An amount equal to the sum of (A) plus (B), where (A) equals
     nine percent (9%) of Six Million Dollars ($6,000,000) multiplied by a
     fraction the numerator of which is the number of days between June 30, 2000
     and the Closing Date and the denominator of which is 365, and (B) equals
     five percent (5%) of Sixty Million Dollars ($60,000,000) multiplied by a
     fraction the numerator of which is the number of days between June 30, 2000
     and the Closing Date and the denominator of which is 365 (the "Purchase
     Price Increase");

               (k) In the event that (A) a SELLER at the time of the Closing has
     in effect any property or casualty insurance covering the Assets or the
     Business, and such insurance covers periods subsequent to the Closing, (B)
     such SELLER cancels such insurance within ten (10) days following the
     Closing, and (C) the policy does not provide for a pro rata refund of such
     premiums paid by such SELLER, the purchase price shall be increased by an
     amount equal to (i) minus (ii), where (i) equals the number of days from
     the Closing Date to the end of the insurance policy period divided by 365
     multiplied by the yearly premium paid, and (ii) equals the amount of the
     insurance premium refunded or to be refunded to such SELLER with respect to
     such policy;
<PAGE>

               (l)  An amount equal to the sum of the deposits referred to in
     Section 3.2(d) below; and

               (m) An amount equal to the replacement capital expenditures
     incurred by SELLERS between June 30, 2000 and the date hereof (and other
     replacement capital expenditures incurred prior to June 30, 2000) as set
     forth on Schedule 3.1(m) hereof and hereby approved by BUYER, plus those
     replacement capital expenditures incurred after the date hereof and prior
     to the Closing that have been approved in writing by BUYER in advance of
     the incurrence; and

the Purchase Price shall be decreased by an amount equal to the sum of the

     SELLERS on the Closing Date as determined from the books and records of
     SELLERS on the Closing Date (the "Customer Deposits"); and

          (y) An amount equal to the sum of (i) bonuses assumed by BUYER
     pursuant to Section 3.3 below and (ii) accrued expenses as of the Closing

     BUYER, including the accrued expenses set forth in Schedule 3.1(y), but
     excluding any unused vacation days; and

          (z) (i) In the event that the promissory note negotiated as part of

     accrued interest under such promissory note as of the Closing Date; and
     (ii) In the event BUYER exercises its right to reject certain real estate
     pursuant to Section 9.15 of this Agreement, the fair market value of any
     real estate which is excluded from this sale as determined by the average
     of the values established by two certified real estate appraisers, with one
     appraiser designated by SELLER and one appraiser designated by BUYER.

          3.2  Long-Term Contracts.  The parties acknowledge that in the
               -------------------
ordinary course of the Business of SELLER(s), SELLER(s) enter into contracts
with third parties providing for the sale of propane to such third parties over
an extended period of time and at a fixed per unit sales price ("Fixed Sales
Contracts"), and SELLER(s) enter into contracts with third parties providing for
the purchase of propane from third parties over an extended period of time at a
fixed per unit sales price ("Fixed Purchase Contracts"). BUYER agrees that at
the Closing it will assume all such Fixed Sales Contracts and Fixed Purchase
Contracts, subject to the following:

               (a) With respect to such contracts entered into after the date
     hereof, such contracts shall have been entered into by SELLER(s) in the
     ordinary course of business consistent with past practices.
<PAGE>

               (b) BUYER shall assume all Fixed Sales Contracts that have been
     entered into by SELLERS prior to or following the date hereof with the
     third parties set forth in Schedule 3.2(b), and the Fixed Sales Contracts
     entered into by SELLERS with any other third parties that, in addition to
     satisfying the provisions of clause (a) above, satisfy the creditworthiness
     standards applied by BUYER in the ordinary course of its business.

               (c) Any such Fixed Sales Contract shall be subject to BUYER
     having offsetting Fixed Purchase Contracts (either assumed hereunder or
     otherwise) and/or long positions of propane inventory that would result in
     BUYER having no worse than a breakeven economic position upon BUYER's
     assumption of such Fixed Sales Contract, and if BUYER would not be in such
     economic position, then BUYER shall nevertheless assume such Fixed Sales
     Contract but the Purchase Price shall be reduced by an amount equal to
     BUYER's reasonably anticipated loss from such Fixed Sales Contract. In
     determining such "reasonably anticipated loss," there shall be taken into
     account the terms of such contracts, the transportation costs, the carrying
     costs of any such propane inventory and the amount payable by BUYER under
     Section 3.2(e) below for the offsetting Fixed Purchase Contract.

               (d) No amount shall be payable by BUYER in connection with the
     assumption by BUYER of any Fixed Sales Contract or any Fixed Purchase
     Contract; provided, however, in the event a SELLER has made any deposit
     with a counterparty to any Fixed Purchase Contract, any unapplied portion
     of such deposit as of the time of Closing shall be paid by BUYER to such
     SELLER as part of the Purchase Price; and provided, further, that with
     respect to any Fixed Purchase Contract, BUYER agrees (i) to pay such
     SELLER's amortized cost thereof that is traceable to the volume to be taken
     under any such contract that is offset against volumes to be sold under any
     Fixed Sales Contract assumed by BUYER under (c) above, and (ii) as to the
     balance of such contract, to pay to such SELLER an amount equal to the
     lower of such SELLER's amortized cost or the market value of such Fixed
     Purchase Contract as of the Closing. Amortized cost of a Fixed Purchase
     Contract shall be based upon industry accounting practice and in accordance
     with GAAP. By way of example of the foregoing proviso, if there is a Fixed
     Sales Contract for 1 million gallons of propane at $.50 per gallon and a
     Fixed Purchase Contract for 1.5 million gallons of propane at $.45 per
     gallon, then the purchase price for such Fixed Purchase Contract would be
     (i) at such SELLER's cost for 1 million gallons, plus (ii) the lower of
     such cost or the current market value for the remaining .5 million gallons.

               (e) BUYER's agreement to assume any Fixed Sales Contract and any
     Fixed Purchase Contract shall be subject to such SELLER obtaining any
     consent of the third party to such contract that would be required to
     permit the assignment of such contract to BUYER.

          3.3  Employee Bonuses.  SELLERS have in place a bonus program for
               ----------------
certain employees of SELLERS. At the time of the Closing, it is anticipated that
there will be bonuses that will have accrued but will not be payable or vested
under such program until a date subsequent to the Closing. Subject to the
provisions hereof, BUYER agrees to assume such bonus liability of SELLERS as
identified to BUYER prior the Closing. The Purchase Price shall be decreased
under Section 3.1(y) above by an amount equal to the sum of the projected
bonuses
<PAGE>

for all employees. In determining the projected bonus for an employee, the
parties shall meet to discuss the anticipated earnings, revenue or other bonus
measurements for the entire bonus period and calculate the bonus based on such
anticipated amounts. Such bonus amount for each employee shall then be
multiplied by a fraction, the numerator of which is the number of days between
the beginning of the bonus period for such employee and the Closing Date and the
denominator of which is 365. By way of example, if (a) an employee is to receive
5% of profits as a bonus for a particular business segment, (b) the profits to
the Closing Date for such segment were $75,000, (c) the number of days between
the beginning of the bonus period and the Closing Date were 300 and (d) the
expected profits (as agreed to by the parties) for such segment for the entire
twelve-month bonus period were $60,000 (i.e., a projected loss of $15,000 for
the remaining 65 days), the bonus amount under this provision would be 300/365
times 5% of $60,000, or $2,465. In addition to BUYER assuming SELLERS' liability
to pay such bonuses under the terms of such SELLER's bonus program, BUYER agrees
that in the event an employee is terminated without cause subsequent to the
Closing Date and the Purchase Price has been decreased pursuant to Section
3.1(y) above with respect to such employee, BUYER agrees to pay to such employee
such credited amount, even though such bonus would not be payable under the
bonus program.

          3.4  Noncompete Payments.  At the Closing on the Closing Date, each
               -------------------
SELLER and each Shareholder (other than Phillip L. Elbert) will enter into a
noncompetition agreement with BUYER in the form of Exhibit A attached hereto
(the "Noncompetition Agreements"), pursuant to which SELLERS and the
Shareholders will receive a total of $465,000 (allocated pursuant to Section
3.5) in consideration for the Noncompetition Agreements. SELLERS and the
Shareholders each hereby agree that such $465,000 is included in the Purchase
Price and will be paid as set forth in the Noncompetition Agreements.

          3.5  Allocation of Purchase Price.  The parties agree to allocate the
               ----------------------------
Purchase Price to the Assets and the Noncompetition Agreements in the manner
provided in Schedule 3.5.

          3.6  Earnest Money Deposit.  Within 14 days after the date hereof,
               ---------------------
BUYER agrees to make an earnest money deposit of Seventy-Five Thousand Dollars
($75,000). Such deposit will be placed in escrow with Bank One, Indiana, N.A.,
Fort Wayne, Indiana and under an escrow agreement in the form attached as
Exhibit H. At the time of the Closing the deposit and interest thereon shall be
returned to BUYER. If the Closing does not occur on or before October 31, 2000
as a result of a breach of this Agreement by any SELLER or any Shareholder,
promptly thereafter BUYER shall be entitled to be paid the deposit and all
interest thereon. If the Closing does not occur on or before October 31, 2000
for any other reason, then SELLERS jointly shall be entitled to be paid $75,000,
and BUYER shall be entitled to be paid the interest thereon.

          3.7  LLC Agreement Amendment and Put Agreement.  At the Closing,
               -----------------------------------------
SELLERS and BUYER agree to execute and deliver to each other the amendment to
limited liability company agreement in the form attached hereto as Exhibit E and
the Put Agreement in the form attached hereto as Exhibit F.

     contemplated by this Section 4.2(a) shall be effected or evidenced by
     delivery by each SELLER to BUYER of bills of sale, assignments and other
     documents of transfer acceptable in form and substance to BUYER.

               (b) BUYER shall assume the liabilities for those accrued expenses
     agreed to be assumed by BUYER as provided in Section 3.1(y) and Schedule
     3.1(y), the liabilities of SELLERS with respect to vacation pay owing to
     SELLERS' employees, the liabilities under SELLERS' bonus program as
     provided in Section 3.3, the liabilities of each SELLER under the Assumed
     Contracts to which such SELLER is a party and such other liabilities of a
     SELLER as BUYER may agree in writing to assume prior to the Closing
     (collectively, the "Liabilities"). Such assumption of the Liabilities shall
     be effected or evidenced by delivery by BUYER to the appropriate SELLER of
     an appropriate written instrument or instruments of assumption acceptable
     in form and substance to such SELLER.

          4.3  Payment of the Purchase Price.  Subject to the terms and

     BUYER or paid to BUYER by SELLERS, as the case may be, within thirty (30)
     days after the Closing.

     however, BUYER agrees to be responsible for all Vehicle Transfer Taxes;

               (d) Any liability (other than with respect to the Liabilities) to
     which any of the parties may become subject as a result of the fact that

     compliance with the provisions of any Bulk Transfer Law or any similar
     statute as enacted in any jurisdiction, domestic or foreign; or

               (e) Any liability with respect to any dispute, claim, complaint

     of each SELLER as and at the relevant dates thereof and for the periods
     covered thereby in accordance with GAAP.

     revenue generated by the Assets as a percentage of such SELLER's total
     revenue for the period beginning one (1) year prior to such SELLER's
     Balance Sheet Date through the Balance Sheet Date and the subsequent period
     ending July 31, 2000 broken down into the following two (2) categories: (i)
     revenues generated from the distribution of propane gas, and (ii) all other
     revenues.

          6.9  Absence of Certain Events.  Except as set forth in Schedule 6.9,
               -------------------------
since the Balance Sheet Date, the Business of each SELLER has been operated only
in the ordinary and normal course of Business and since the Balance Sheet Date:

               (a) There has not been any Material Adverse Effect in the
     financial condition, Assets, liabilities, results of operations, Business,

          6.10  Title to and Condition of Properties.
                ------------------------------------

                (a) Schedule 2.1A contains a true, correct and complete list of
     all real property related to the operation of the Business in which any
     SELLER has any interest. Schedule 2.1B contains a true, correct and
     complete list of all leases and subleases of real and mixed property
     related to the operation of the Business under which any SELLER is a lessor
     or lessee (true, accurate and complete copies of which have previously been
     delivered to BUYER). Each SELLER has good, marketable and indefeasible fee
     simple title to all of its real properties, including but not limited to
     the real properties in which it has an interest as described on Schedule
     2.1A, but not including any leased property, and good, marketable and
     indefeasible title to all the leasehold estates created by the leases and
     subleases described on Schedule 2.1B (such real properties and leasehold
     estates collectively referred to herein as the "Real Property"). Without
     limiting the generality of the foregoing, as to leasehold estates under the
     leases and subleases of Real Property, each SELLER has quiet and peaceable
     possession of each of the leased properties. All leases and subleases in
     which a SELLER is a lessor or sublessor are in full force and effect, there
     is no default or event of default thereunder and the rent thereunder has
     not been prepaid for more than a one (1)-month period. Each SELLER has and
     upon the transfer to BUYER as contemplated herein BUYER has rights of
     ingress and egress to all of its real properties and to all its leasehold
     estates, subject to the local zoning and development restrictions.

                (b) A true, correct and complete list of all propane tanks which
     are owned or serviced by any SELLER and all other personal property
     included in the Assets having a fair market or book value per unit in
     excess of Two Hundred Fifty Dollars ($250) is included in Schedule 2.1C and
     a true, correct and complete list of all leases of personal property
     included in the Assets under which any SELLER is a lessee or lessor
     involving any propane tank or any other personal property having a fair
     market or book value per unit in excess of Two Hundred Fifty Dollars ($250)
     is included in Schedule 2.1D (true, accurate and complete copies of which
     have previously been delivered to BUYER). Notwithstanding any other
     provision of this Agreement, SELLERS and the Shareholders shall have
     liability for the inaccuracy of the representations made in the first
     sentence of this Section 6.10(b) only to the extent such inaccuracy exceeds
     One Hundred Thousand Dollars ($100,000) in propane tank value (as measured
     by the replacement cost of any such propane tank) and then only if the
     claim for such inaccuracy is made by notice to SELLERS and the Shareholders
     given by BUYER prior to the Accounts Receivable Date. All propane tanks
     used in the Business which have a capacity of at least one hundred twenty
     (120) gallons are under contract to customers or are physically located on
     the plant lot of one of such SELLER's retail locations. Each SELLER has
     good and indefeasible title to (i) all of the personal property set forth
     on Schedule 2.1C and indicated as being owned by it, (ii) all of the Assets
     reflected in the financial statements of each SELLER, and (iii) all Assets
     purported to have been acquired by such
<PAGE>

     SELLER after the date of such financial statements, free and clear of all
     Liens (except for Permitted Encumbrances), except for such Assets disposed
     of in the usual and ordinary course of business consistent with past
     practices, and all of such Assets are in such SELLER's possession and
     control.

                (c) The conduct of the Business of each SELLER in the ordinary
     course is not dependent upon the right to use the property of others,
     except under valid and binding agreements identified on Schedule 6.10(c)
     hereto (true, accurate and complete copies of which have previously been
     delivered to BUYER). To the Knowledge of any SELLER, the Real Property and
     the improvements located thereon do not encroach upon the property of
     others and there are no encroachments onto the Real Property from the
     property of others. SELLERS have had access to all utility connections, and
     the right to use the same, necessary for the conduct of the Business in the
     ordinary course.

                (d) Except as set forth in Schedule 6.10(d), each SELLER owns or
     has irrevocable rights to use and is transferring to BUYER hereunder all
     assets and property necessary for the conduct of such SELLER's Business in
     the ordinary course.

                (e) The Assets being transferred by each SELLER, including, but
     not limited to, the machinery, equipment (including automobiles, trucks and
     heavy machinery), furniture and fixtures are in good operating condition
     and repair and of an appropriate character suitable for the uses for which
     intended in the operation of the Business of such SELLER in the ordinary
     course, except that at any given time approximately three (3) to five (5)
     percent of the automobiles, trucks and heavy machinery being transferred
     hereunder will be in the process of being repaired or refurbished.

                (f) All inventories of each SELLER are of a quality and quantity
     usable and salable in the ordinary course of such SELLER's Business and in
     any event are not in excess of projected requirements over the next twelve
     (12) months, and the values at which such inventories are carried on the
     books of account fairly represent the value thereof, are not in excess of
     realizable value, and reflect the normal inventory valuation policy of such
     SELLER.

                (g) The accounts receivable of each SELLER as shown on its books
     and records have arisen in the ordinary course of Business, represent valid
     and enforceable obligations owed to such SELLER and are recorded as
     accounts receivable on the books of such SELLER in accordance with GAAP.

          6.11  Intangible Properties.
                ---------------------

                (a) Schedule 2.1J hereto contains a list of all patents and
     applications therefor, trademarks, trademark registrations and applications
     therefor, trade names, service marks, copyrights, copyright registrations
     and applications therefor, both foreign and domestic, owned, possessed,

     such SELLER's Business and such SELLER owns the entire right, title and
     interest in and to the same, together with the goodwill associated
     therewith. Each SELLER has the right to use and is transferring to BUYER
     the unrestricted right to use
<PAGE>

     trade secrets, know-how, formulae, technical processes and information,
     manufacturing, testing and operating techniques and procedures, all
     engineering data and plans and all other data and information used by such
     SELLER in its Business or which is necessary for its Business as now
     conducted. None of the items in the categories listed in the preceding
     sentence of this Section 6.11 are subject to any pending or threatened
     challenge or infringement, and no impediment exists as to such SELLER's
     exclusive ownership and use or validity of any such item, except as set
     forth in Schedule 2.1J. The foregoing constitutes all information necessary
     to permit the conduct from and after the Closing Date of the Business of
     each SELLER, as such Business is and has normally been conducted. All acts
     necessary under all provisions of applicable law to protect the items
     listed on Schedule 2.1J, including, without limitation, the filing of
     required affidavits of use and incontestability, applications for renewals
     of registrations and notice of registration, have been taken by each
     SELLER. All licenses granted to each SELLER by others which are essential
     or useful to any part of such SELLER's Business are assignable to BUYER
     without consent of or notice to any Person, without change in the terms or
     provisions thereof and without premium, except as set forth in Schedule
     2.1J. With respect to each SELLER, such SELLER has not infringed any
     unexpired patent, trademark, trademark registration, trade name, copyright,
     copyright registration, trade secret or any other proprietary or
     intellectual property right of any party in connection with the operation
     of its Business. No SELLER has given any indemnification for patent,
     trademark, service mark or copyright infringements.

                (b) Schedule 2.1K hereto contains a list, of each SELLER's trade
     secrets related to the operation of its Business.

     party to any contract for goods or services or any lease with any officer,
     director, shareholder, employee or agent of SELLER or any Affiliate of any
     such Person.

                (c) No purchase or sale commitments by any SELLER are in excess

be maintained in effect up to and including the Closing Date. Each SELLER will,
at the request of BUYER, use its best efforts to cause the policies of insurance
against fire and other casualty to property to be endorsed so as to include

<PAGE>

     plan" as defined in Section 3(3) of the Employee Retirement Income Security
     Act of 1974, as amended ("ERISA"), (i) to which such SELLER is a party or a
     sponsor or a fiduciary thereof, or (ii) with respect to which such SELLER
     has made payments, contributions or commitments, or may otherwise have any
     liability (collectively, the "Benefit Plans"). With respect to the Benefit
     Plans, individually and in the aggregate, each SELLER has made available to
     BUYER, a true and correct copy of (a) the most recent annual report (Form

     (except liability for benefits, claims and funding obligations payable in
     the ordinary course) under ERISA, the Code, or any other applicable
     statute, order or governmental rule or regulation. With respect to the
     Benefit Plans, individually and in the aggregate, there has been no
     prohibited transaction within the meaning of Section 406 of ERISA or
     Section 4975 of the Code that would result in liability to any SELLER, and
     there has been no action, suit, grievance, arbitration or other claim with
     respect to the administration or investment of assets of the Benefit Plans
     (other than routine claims for benefits made in the ordinary course of plan
     administration) pending, or to the Knowledge of any SELLER, threatened.

                (c) All contributions to and payments under any Benefit Plan
     required in respect of periods ending on or before the Closing Date shall
     be made by each SELLER on or within thirty (30) days after the Closing
     Date. There is no agreement, contract or understanding between any SELLER,
     on the one hand, and any employee, participant, labor union, collective
     bargaining unit or other Person, on the other hand, that requires or may
     require any amendment to any of the Benefit Plans.

                (d) Each Benefit Plan that is intended to be tax qualified under
     Section 401(a) of the Code is tax qualified and each such Benefit Plan has
     received, or application has been made for, a favorable determination
     letter from the IRS stating that the Plan meets the requirements of the
     Code and that any trust or trusts associated with the Plan are tax exempt
     under Section 501(a) of the Code. Each Benefit Plan that is funded with a
     trust that is intended to be tax-exempt under Section 501(c)(9) of the Code
     is exempt from taxation and each such trust has received a letter from the
     IRS stating that the trust meets the requirements of the Code for
     tax-exempt status, within the immediately preceding three (3)-year period.

                (e) No SELLER and no entity that together with any SELLER would
     be deemed to be a "single employer" within the meaning of Section 414(b),
     (c), (m) or (o) of the Code now maintains or contributes to or, within the

Proposal or otherwise facilitate any effort or attempt to make or implement an
Acquisition Proposal. Each SELLER and each Shareholder will: (a) immediately
cease and cause to be terminated any existing activities, discussions or
negotiations with any Persons conducted heretofore with respect to any of the
foregoing, and each will take the steps necessary to inform such Persons of the
obligations
<PAGE>

undertaken in this Section 9.10, and (b) notify BUYER immediately if any such
inquiries or proposals are received by, any such information is requested from,
or any such discussions or negotiations are sought to be initiated or continued
with, any SELLER or any Shareholder.

          9.11  Supplemental Information.
                ------------------------

                (a) SELLERS, the Shareholders and BUYER each agree that, with
     respect to the representations and warranties of such party contained in
     this Agreement, such party will have the continuing obligation until the
     Closing to promptly provide the other party with such additional
     supplemental information (collectively, the "Supplemental Information"), in
     the form of (i) amendments to then existing Schedules (ii) Additional
     Schedules, as would be necessary, in light of the circumstances,
     conditions, events and states of fact then known, to make each of those
     representations and warranties true and correct as of the Closing, or (iii)
     for purposes only of determining whether the conditions to the obligations
     of BUYER have been satisfied, the Schedules to this Agreement as of the
     Closing Date will be deemed to be the Schedules to this Agreement as of the
     date hereof as amended or supplemented by the Supplemental Information
     provided to BUYER prior to the Closing pursuant to this Section 9.11;
     provided, however, that if the Supplemental Information so provided
     discloses the existence of circumstances, conditions, events or states of
     facts that, in any combination thereof, (i) have had a Material Adverse
     Effect on any SELLER, (ii) in the sole judgment of BUYER are having or will
     have a Material Adverse Effect on any SELLER or (iii) represent a breach of
     Section 9.1 above, BUYER will be entitled to terminate this Agreement by
     notice to SELLERS; and provided, further, that if the facts first disclosed
     in the Supplemental Information were required to be disclosed at the time
     of signing of this Agreement but were not, and BUYER does not terminate the
     Agreement and proceeds to Closing, then BUYER will be entitled to be
     indemnified for all Damages that are attributable to such failure to
     disclose by SELLER(s) or the Shareholders.

                (b) Additionally, notwithstanding any other provision herein to
     the contrary, no SELLER and no Shareholder shall have any liability to
     BUYER for the breach of any covenant contained in Section 9.1 above if (i)
     such breach was not the result of conduct knowingly intended to result in
     such a breach and (ii) such breach is disclosed to BUYER in the
     Supplemental Information.

          9.12  Concerning the IPO.
                ------------------

                (a) The parties recognize that a condition to BUYER's obligation
     to purchase the Assets and consummate the transactions contemplated herein
     is the securing by BUYER of the necessary financing for the cash portion of
     the Purchase Price (see Section 10.16). It is BUYER's intention to arrange
     for the organization of a master limited partnership (the "MLP") that would
     acquire the Business and Assets of SELLERS and other businesses and assets
     that are similar to such Business and Assets from third parties and
     concurrently effect a public offering of units of the MLP (the "IPO") in a
     manner similar to public offerings made by publicly traded master limited
     partnerships that are engaged in the distribution and sale of propane.
     Accordingly, BUYER agrees to proceed in good faith to make appropriate
     arrangements to make such acquisitions, secure an underwriter for the IPO
     and proceed with the IPO.
<PAGE>

                (b) SELLERS and the Shareholders recognize that there are many
     matters that must be completed before the IPO can be accomplished and
     accordingly, there will be several months of work by BUYER on such matters.
     In addition, it is recognized that, due to the nature of such matters, the
     IPO may not be able to be completed at all, whether for legal, business or
     other reasons, including unfavorable market conditions, prices or rates.

                (c) It is agreed that BUYER shall have full control over the
     manner, timing and other matters related to the IPO, subject only to the
     specific agreements herein contained.

                (d) While the parties recognize that the proceeds of the IPO are
     anticipated to provide the funds necessary for the purchase from SELLERS of
     the Assets, BUYER may have other funding sources and completion of the IPO
     is not a condition to any SELLER's or any Shareholder's obligations to
     consummate the purchase and sale of the Assets and Business.

                (e) As used herein, "Registration Statement" means the
     registration statement filed with the Federal Securities and Exchange
     Commission to register the sale of MLP units in connection with the IPO. If
     BUYER (or the MLP or other appropriate entity) shall not have filed a
     Registration Statement on or prior to October 31, 2000, then any SELLER may
     terminate this Agreement by notice thereof to BUYER.

                (f) Each SELLER will provide BUYER with all the information
     concerning such SELLER that is reasonably requested by BUYER, from time to
     time in connection with the IPO; provided, however, in connection with the
     foregoing or in connection with SELLERS' agreement contained in Section
     9.13 below, SELLERS shall not be required to incur out-of-pocket costs in
     excess of Fifteen Thousand Dollars ($15,000). Each SELLER hereby represents
     and warrants that any financial statements of such SELLER provided for
     inclusion in the Registration Statement have been prepared in accordance
     with GAAP.

                (g) BUYER agrees that from time to time it will advise SELLERS
     as to the status of BUYER's efforts regarding the IPO.

                (h) Notwithstanding any other provision of this Agreement to the
     contrary, BUYER shall have the right to disclose such information
     concerning SELLERS, the Shareholders, the Assets, the Business and this
     Agreement as BUYER and its counsel deem necessary or appropriate in
     connection with the IPO without obtaining any prior consent of SELLERS or
     the Shareholders, provided that any SELLER or Shareholder will be provided
     with copies of all such disclosures upon request.

          9.13  Additional Financial Statements.  Each SELLER agrees to furnish
                -------------------------------
to BUYER:

                (a) as soon as available and in any event within thirty (30)
     days after the end of each SELLER's fiscal quarters that ends prior to the
     IPO, an unaudited balance sheet of such SELLER as of the end of such fiscal
     quarter and the related statements of income or operations, cash flows and
     shareholders' equity for such fiscal quarter and for
<PAGE>

     the period of such SELLER's fiscal year ended with that quarter, in each
     case (i) setting forth in comparative form the figures for the
     corresponding portion of the such SELLER's previous fiscal year, and (ii)
     prepared in accordance with GAAP (x) throughout the periods indicated
     (excepting footnotes) and (y) on the same basis as the financial statements
     referred to in Section 6.8 were prepared; and

                (b) if requested by BUYER in connection with any amendment of
     the Registration Statement and promptly following any such request, a
     balance sheet, statements of income or operations, cash flows and
     shareholders' equity of such SELLER as of the end of either the first or
     second fiscal month in any of such SELLER's fiscal quarters as BUYER may
     request.

          9.14  HSR Act.
                -------

                (a) If filings pursuant to and under the HSR Act are required in
     connection with the consummation of the transactions contemplated by this
     Agreement, BUYER and each SELLER promptly will compile and file (or will
     cause its "ultimate parent entity" (as determined for purposes of the HSR
     Act) to file) under the HSR Act such information respecting such party as
     the HSR Act requires of an entity to be acquired. HSR filing fees will be
     paid by BUYER, but each SELLER shall pay all other expenses incurred in
     connection with the preparation of any of the reports and other information
     that it is required to file.

                (b) If BUYER determines that a filing under the HSR Act is not
     required and the failure to file causes any Shareholder or any SELLER to
     incur Damages (as defined in Section 12.1B), then BUYER agrees to indemnify
     such SELLER and such Shareholder as provided in Section 12.2.

          9.15  Title Insurance.  Subject to the provisions of this Section
                ---------------
9.15, on the Closing Date, each SELLER shall, at such SELLER's expense, cause to
be issued and delivered to BUYER a policy of title insurance (the "Title
Policy") respecting the Real Property and conforming to the following
specifications:

                (a) The form of the policy will be ALTA Owner's Policy Form B
     1970 (amended 10/17/70), or as to leasehold estates, ALTA Leasehold Owner's
     Policy - 1975, or the approved form, for the jurisdiction in which the Real
     Property is located, that is the substantial equivalent thereof;

                (b)  The policy will be issued by a mutually acceptable
     insurance company (the "Title Company");

                (c)  The insured will be BUYER;

                (d)  The policy will be in an amount reflecting the value
     thereof as agreed to by BUYER and SELLERS;

                (e)  The policy will be dated concurrent with or subsequent to
     the Closing;
<PAGE>

                (f) There will be no exceptions to coverage other than the
     Permitted Encumbrances. Without limiting the generality of the foregoing
     provisions hereof, the Title Policy shall not contain any exceptions with
     respect to:

                     (A) Rights or claims of parties in possession;

                     (B) Encroachments, overlaps, boundary line disputes or any
               other matters that would be disclosed by an accurate survey and
               inspection (provided that the Survey is sufficient to enable the
               title insurance company to delete such exceptions pursuant to the
               title company's standard underwriting requirements);

                     (C) Easements or claims of easements not shown by the
               public records (provided that the Survey is sufficient to enable
               the title insurance company to delete such exceptions pursuant to
               the title company's standard underwriting requirements);

                     (D) Any lien, or right to a lien, for services, labor or
               materials heretofore or hereafter furnished; and

                     (E) Any other exceptions that may be designated or included
               as standard exceptions in the area where the Real Property is
               located.

                (g) The policy shall contain such additional coverages and
     endorsements as BUYER may request or require, provided, however, any
     additional expense for such additional coverages or endorsements shall be
     paid by BUYER.

Within thirty (30) days after the date hereof, each SELLER shall deliver to
BUYER (i) a current commitment from the Title Company setting forth the basis
upon which the Title Company is willing to insure title to the Real Property
(the "Title Commitment"), and (ii) a current boundary survey of the Real
Property, prepared at such SELLER's expense (the "Survey"). The Survey shall be
prepared and certified to BUYER by a registered land surveyor or licensed civil
engineer (registered or licensed in the state where the Real Property is
located) showing (i) the boundaries and legal descriptions of such Real
Property, (ii) the location of all roadways and other accessways upon, across or
adjacent to such premises, and (iii) such other matters and items as BUYER may
request, provided that BUYER shall pay any additional expense charged by the
surveyor for such additional items. The surveyor shall locate or set bars at all
corners of the surveyed property and shall reflect the same on the Survey. If
the Title Commitment or the Survey disclose any liens, easements, restrictions,
reservations or other defects or any other matters objectionable to BUYER, BUYER
shall advise the appropriate SELLER of the same in writing within ten (10) days
after receipt by BUYER of the Title Commitment and the Survey. Matters not
objected to by BUYER within said period shall be deemed to be Permitted
Encumbrances. As to any matters to which BUYER objects, such SELLER shall use
reasonable commercial efforts to resolve the objections (but with no requirement
to make any out-of-pocket expenditures except to satisfy mortgages or liens) and
shall, within ten (10) days after BUYER gives such SELLER notice of objection to
such matters, have delivered to BUYER a revised Title Commitment and/or Survey
reflecting that such remedy has been effected. In the event such SELLER is
unable to deliver the Title Policy or the Survey in accordance with the
foregoing requirements, BUYER's sole remedy therefor shall be either of the
following options:
<PAGE>

(x) consummating the transaction
contemplated hereby and accepting such title as such SELLER holds, without
change in or to the terms hereof, unless such matters are encumbrances or liens
for an ascertainable amount, in which case such SELLER shall pay the amount
thereof to BUYER in cash at the Closing and thereby waive any claims under
Section 12.1 of this Agreement with respect to such objections, or (y) rejecting
and excluding the subject property from the transaction contemplated by this
Agreement, exercising its rights under Section 3.1(z)(ii) to have the purchase
price reduced and entering into a lease agreement respecting such property in
the form of the Lease Agreement attached hereto as Exhibit J. If Buyer elects
option (y), then BUYER and such SELLER owning such property agree to enter into
the aforementioned Lease Agreement.

          9.16  Employee Matters.
                ----------------

                (a) Schedule 9.16(a) sets forth a list of all salaried and
     hourly employees employed by each SELLER and such employees' current
     compensation. All of such employees are employed at the will of such SELLER
     and may be terminated without notice and without cause except as set forth
     in Schedule 9.16(a). On the Closing Date, BUYER shall offer employment to
     all persons who were employed by each SELLER on the Closing Date (other
     than any Shareholder so employed) in a position and at a base salary
     substantially equivalent to such employee's present position and base
     salary. Except as set forth in Schedule 3.1(y), Section 4.2(b) and 9.16(b),
     BUYER shall have no liability for any salary or benefits accrued prior to
     the Closing Date.

                (b) COBRA. Except as otherwise provided in Schedule 9.16(b), no
     person is currently covered under any SELLER's health plan as a result of
     an election under the Consolidated Omnibus Budget Reconciliation Act, as
     amended, and the Tax Reform Act of 1986 ("COBRA"). BUYER agrees to offer
     group health plan coverage in a manner that will satisfy SELLERS'
     obligation to offer COBRA coverage with respect to the following persons:
     (i) those persons whose employment with a SELLER has terminated prior to
     the date hereof and who have elected COBRA coverage under any SELLER's
     health plan after the date hereof, and (ii) any person whose employment
     with a SELLER has terminated after the date hereof and prior to the Closing
     Date (including those that did not accept BUYER's offer of employment) and
     who has elected COBRA coverage under any SELLER's health plan; provided,
     however, the foregoing agreement of BUYER shall not apply to any of the
     Shareholders or their family members. Any person included within the above
     clauses (i) or (ii) and that accepts such offer of COBRA coverage by BUYER
     is referred to herein as a "Covered Person." In the event that, in any plan
     year of BUYER's group health plan, a Covered Person shall incur medical
     costs that are reimbursed or paid for under BUYER's group health plan in
     excess of Two Thousand Five Hundred Dollars ($2,500), then SELLERS agree to
     pay to BUYER the amount by which such medical costs exceed such amount up
     to a maximum liability of SELLERS to BUYER in any such plan year for any
     such person of Twenty-Seven Thousand Five Hundred Dollars ($27,500),
     provided that SELLERS shall not be obligated to reimburse BUYER for
     expenses incurred by any such individual after BUYER reaches the aggregate
     attachment point for BUYER's plan year in question. Notwithstanding the
     foregoing, SELLERS shall be responsible for all COBRA obligations of those
     individuals listed in Schedule 9.16(b) and SELLERS shall purchase at their
     own expense an insurance policy to cover such listed individuals.
<PAGE>

                (c) Health Care for Employees Hired by Buyer. BUYER agrees to
     offer group health plan coverage on the same terms and conditions as apply
     to BUYER's existing employees to employees of SELLER who accept employment
     immediately after Closing with BUYER, except that each such employee shall
     (i) be eligible for such coverage on their date of hire by BUYER, and (ii)
     receive credit, for purposes of BUYER's group health plan for its plan year
     ending December 31, 2000, for any deductibles under SELLER's health plan
     during 2000.

                (d) Employment-Related Claims. Subject to the provisions of
     Sections 9.16(a), (b) and (c), each SELLER assumes all liability, costs and
     expenses (including reasonable attorneys' fees) for all existing employment
     claims that have been filed by any employee or former employee of such
     SELLER prior to the Closing Date relating to arbitrations, unfair labor
     practice charges, employment discrimination charges, lawsuits, any
     employment- related tort claim or other claims or charges of or by
     employees of such SELLER or any thereof filed after the Closing Date but
     arising as a result of actions or events or series of actions or events
     that occurred prior to the Closing Date. Schedule 9.16(d) sets forth a
     brief description of all such claims that have been filed as of the date
     hereof. Each SELLER shall promptly describe to BUYER in writing a brief
     description of any of such claims that may be filed after the date hereof
     but on or before the Closing Date.

                (e) 401(k) Plan. SELLERS shall, prior to the Closing Date, adopt
     any and all resolutions that are necessary or appropriate to (i) fund the
     401(k) Profit Sharing Plan, as referenced in Schedule 6.18(a), (the "401(k)
     Plan"), with any profit sharing and/or matching contributions that have
     accrued as of the Closing Date or that otherwise customarily and
     historically would have been made by the SELLERS prior to the 401(k) Plan
     year end; (ii) except as provided immediately above, cease all other
     contributions to the 401(k) Plan immediately before the Closing Date; (iii)
     terminate the 401(k) Plan; (iv) fully vest all participant account balances
     in the 401(k) Plan immediately before the Closing Date; and (v) provide for
     distribution of the assets of the 401(k) Plan following receipt of a
     favorable determination letter (which shall be obtained by SELLERS, at
     their expense) from the Internal Revenue Service with respect to the
     termination and distribution of the assets of the 401(k) Plan.

          9.17  SELLERS' and Shareholders' Access to Records.  For a period of
                --------------------------------------------
at least six (6) years from the Closing Date, BUYER shall retain all books,
records and accounts of each SELLER. In the interests of facilitating each
SELLER and the Shareholders in the completion of their respective tax forms,
BUYER shall make available to copy at such SELLER's or Shareholder's expense
such books, records and accounts during normal business hours, and BUYER shall
not destroy any of such SELLER's books and records without reasonable advance
notice to such SELLER and without granting a reasonable opportunity for such
SELLER to take and retain possession of any and all such books and records at
such SELLER's expense.

          9.18  Heller Agreement.  Investors 300, Inc. and BUYER agree to work
                ----------------
toward an amendment of that certain Covenant Not to Compete dated August 11,
1998, by and among Investors 300, Inc., Candace J. Heller and Ronald Heller to
(i) permit the assignment of the rights of Investors 300, Inc. to BUYER, (ii)
permit BUYER to assume the promissory note without such promissory note being
payable in full on the Closing Date, and (iii) relieve Investors 300, Inc. from
any liability under the promissory note.
<PAGE>

          9.19  Environmental Studies.
                ---------------------

                (a) Prior to the Closing, BUYER shall have the right, at BUYER's
     expense, to undertake such environmental studies on real estate to be
     acquired or leased pursuant to this Agreement as BUYER deems, in its sole
     discretion, appropriate. Prior to the execution of this Agreement, BUYER,
     at its expense, has been provided with an environmental audit of SELLERS'
     properties at Kendallville and Waterloo, Indiana ("Kendallville and
     Waterloo Properties"). The remaining provisions of this Section 9.19 do not
     apply to the Kendallville and Waterloo Properties.

                (b) With respect to the real estate owned or leased by SELLERS,
     save for and excluding the Kendallville and Waterloo Properties (the "Other
     Properties"), in the event any such environmental study reveals, prior to
     Closing, any situation such that remediation or other corrective action is,
     in BUYER's judgment, required by law, then BUYER shall notify SELLERS of
     such fact, and SELLERS shall have ten (10) days to object to such proposed
     remediation. If SELLERS object to such remediation within said ten (10) day
     period by notice in writing to BUYER given within said ten (10) day period,
     then the parties will meet to discuss and resolve their differences, and if
     no agreement is reached, then a firm that is a recognized expert in
     environmental remediation matters selected by SELLERS' and BUYER's
     environmental firms that performed such studies shall meet to reach
     agreement, and if they cannot reach agreement, then a third firm that is a
     recognized expert in environmental matters shall be selected by such two
     firms, and the third firm shall decide if remediation is required by law,
     and if yes, provide an estimate as to how much it will cost to perform such
     remediation, and the decision by such third firm shall be binding upon the
     parties.

                (c) If remediation of any parcel of the Other Properties is to
     be effected or other action is to be taken, SELLERS shall cooperate and
     assist BUYER in taking such action as to remediate such property.

                (d) At the Closing, SELLERS agree to reimburse BUYER for up to
     One Hundred Thousand Dollars ($100,000) per parcel of the Other Properties
     for the out- of-pocket amounts spent by BUYER prior to the Closing with
     respect to such remediation in accordance with the provisions of this
     Section 9.19. SELLERS' obligation to reimburse BUYER is contingent upon the
     occurrence of the Closing on all the transactions contemplated by this
     Agreement. The obligations of SELLERS under this Section 9.19 shall not
     affect the liability of SELLERS with respect to the environmental condition
     of the Other Properties under any other representation, warranty or
     provision of this Agreement. For purposes of this Section 9.19(d), the term
     "out-of- pocket amounts" shall not include any attorneys' fees or
     consultants' fees incurred prior to the commencement of a remediation.

                ARTICLE 10. CONDITIONS TO BUYER'S OBLIGATION TO
                -----------------------------------------------
                           CONSUMMATE THE TRANSACTION
                           --------------------------

          Each and every obligation of BUYER to be performed at or before the
Closing hereunder is subject, at BUYER's election, to the satisfaction on or
prior to the Closing Date of the conditions set forth below. Notwithstanding the
failure of any one or more of such conditions, BUYER may nevertheless proceed
with Closing without satisfaction, in whole or in
<PAGE>

part, of any one or more of such conditions, but which action shall not
prejudice BUYER's right to recover Damages for any such failure.

          10.1  Compliance with Agreement.  Each SELLER and each Shareholder
                -------------------------
shall have performed all of their respective obligations and agreements, and
complied with all covenants, warranties and conditions contained in this
Agreement that are required to be performed or complied with by such party on or
prior to the Closing Date.

          10.2  Representations and Warranties.  The representations and
                ------------------------------
warranties of each SELLER and each Shareholder contained in this Agreement (as
supplemented pursuant to Section 9.11) shall be true, complete and correct on
and as of the Closing Date with the same force and effect as though such
representations and warranties had been made or given on the Closing Date.

          10.3  Certificate.  Each SELLER and each Shareholder shall have
                -----------
delivered to BUYER a certificate, dated the Closing Date (in the case of each
SELLER, signed by such SELLER's duly authorized officers) to the effect stated
in Sections 10.1 and 10.2.

          10.4  Corporate Authorization.  BUYER shall have received a copy of
                -----------------------
the resolutions of the directors and shareholders of each SELLER, certified as
of the Closing Date by the secretary or assistant secretary of such SELLER, duly
authorizing the execution, delivery and performance by such SELLER of this
Agreement and each other agreement and instrument contemplated hereby, together
with an incumbency certificate as to the persons authorized to execute and

     Kendallville and Waterloo Environmental Claims against the Environmental
     Escrow
<PAGE>

     must be made on or before three (3) years after the Closing Date (it being
     understood and agreed that the resolution of any such claim may extend
     beyond such three (3) year period) and if made within such three-year
     period, claims hereunder for reimbursement of out-of-pocket amounts spent
     shall be resolved within five (5) years after the Closing Date.

                (d) BUYER shall have the right to make claims (the "Other

     relating to:

                     (A) Environmental contamination or other environmental

               indemnification otherwise under applicable environmental laws now

               respect to such claims is as set forth in this Section 12.1A.

                (e) As for the Other Properties Environmental Claims, claims for
     indemnification hereunder shall be limited as follows: (i) BUYER shall be
     able to claim and be reimbursed only for all out-of-pocket amounts spent by
     BUYER to correct the condition of such Other Property that gave rise to the
     claim of BUYER under Section 12.1A(d) above, (ii) with respect to each
     parcel of real estate included in the Other Properties, once SELLERS and
     the Shareholders have paid to BUYER a total of $100,000 with respect to
     Other Properties Environmental Claims relating to such parcel of real
     estate, then SELLERS shall have no further liability under Section 12.1A(d)
     with respect to such parcel of real estate, and (iii) claims made under
     Section 12.1A(d) shall be made within two years after the Closing Date, and

     Closing Date. For purposes of this Section 12.1A(e), the term "out-of-
     pocket amounts" shall not include any attorneys' fees or consultants' fees
     incurred prior to the commencement of a remediation.

                (f) Except for the rights granted to BUYER in this Section
     12.1A, as for the environmental condition of the Kendallville and Waterloo
     Properties and the Other Properties, BUYER hereby releases and gives up all
     claims, causes of action, or rights, known or unknown, including without
     limitation rights to or claims for contribution or indemnification under
     applicable environmental laws now existing or hereafter amended or enacted,
     that BUYER may have against SELLERS and/or the Shareholders arising from or
     relating to the Kendallville and Waterloo Properties or the Other

     the Other Properties to BUYER hereunder.

          12.3  Limitations on Liability of SELLERS and the Shareholders.
                --------------------------------------------------------
Notwithstanding anything to the contrary in this Article 12 or any of the other
terms and
<PAGE>

conditions of this Agreement, SELLERS' and Shareholders' liability and BUYER's
claims under this Article 12 shall be limited as follows:

                (a) SELLERS and the Shareholders shall have no liability or
     obligation to indemnify under this Article 12 arising from a breach by the
     other Shareholders or SELLERS under the Noncompetition Agreements (the
     rights and remedies of the parties under the Noncompetition Agreements are
     as set forth in the Noncompetition Agreements);

                (b) With respect to a claim for indemnification based on a
     breach of a representation or warranty as set forth in Section 6.21 of this
     Agreement (i) with respect to the Kendallville and Waterloo Properties, the
     sole and exclusive remedy of BUYER is to make a claim against the
     Environmental Escrow pursuant to Section 12.1A above and (ii) with respect
     to the Other Properties, the liability of SELLERS shall be limited as set
     forth in Section 12.1A; and

                (c) All such claims shall be subject to the time limitation (if
     applicable) set forth in Section 13.1 of this Agreement.

          12.4  Procedure.  All claims for indemnification by a party under this
                ---------
Article 12 (the party claiming indemnification and the party against whom such
claims are asserted being hereinafter called the "Indemnified Party" and the
"Indemnifying Party," respectively) shall be asserted and resolved as follows:

                (a) In the event that any claim or demand for which an
     Indemnifying Party would be liable to an Indemnified Party hereunder is
     asserted against or sought to be collected from such Indemnified Party by a
     third party, such Indemnified Party shall with reasonable promptness give
     notice (the "Claim Notice") to the Indemnifying Party of such claim or
     demand, specifying the nature of and specific basis for such claim or
     demand and the amount or the estimated amount thereof to the extent then
     feasible (which estimate shall not be conclusive of the final amount of
     such claim and demand). The Indemnifying Party shall not be obligated to
     indemnify the Indemnified Party under this Agreement with respect to any
     such claim or demand if the Indemnified Party fails to notify the
     Indemnifying Party thereof in accordance with the provisions of this
     Agreement, and, as a result of such failure, the Indemnifying Party's
     ability to defend against the claim or demand is materially prejudiced. The
     Indemnifying Party shall have twenty (20) days from the delivery or mailing
     of the Claim Notice (the "Notice Period") to notify the Indemnified Party
     (i) whether or not it disputes the liability of the Indemnifying Party to
     the Indemnified Party hereunder with respect to such claim or demand, and
     (ii) whether or not it desires, at the cost and expense of the Indemnifying
     Party, to defend the Indemnified Party against such claim or demand;
     provided, however, that any Indemnified Party is hereby authorized, but is
     not obligated, prior to and during the Notice Period, to file any motion,
     answer or other pleading that it shall deem necessary or appropriate to
     protect its interests or those of the Indemnifying Party. If the
     Indemnifying Party notifies the Indemnified Party within the Notice Period
     that it desires to defend the Indemnified Party against such claim or
     demand, the Indemnifying Party shall, subject to the last sentence of this
     paragraph, have the right to control the defense against the claim by all
     appropriate proceedings and any settlement negotiations, provided that to
     the satisfaction of the Indemnified Party, the Indemnifying Party shall
<PAGE>

     secure the Indemnified Party against such contested claims by posting a
     bond or otherwise. If the Indemnified Party desires to participate in, but
     not control, any such defense or settlement, it may do so at its sole cost
     and expense. If the Indemnifying Party fails to respond to the Indemnified
     Party within the Notice Period, elects not to defend the Indemnified Party,
     or after electing to defend fails to commence or reasonably pursue such
     defense, then the Indemnified Party shall have the right, but not the
     obligation, to undertake or continue the defense of, and to compromise or
     settle (exercising reasonable business judgment), the claim or other matter
     all on behalf, for the account and at the risk of the Indemnifying Party.
     Notwithstanding the foregoing, if the basis of the proceeding relates to a
     condition of operations that existed or were conducted both prior to and
     after the Closing Date or if the Indemnified Party would be otherwise
     adversely affected as a result of any adverse decision of such proceeding,
     each party shall have the same right to participate at its own expense and
     at its own risk (but without waiving any right to indemnification
     hereunder) in the proceeding without either party having the right of
     control.

                (b) If requested by the Indemnifying Party, the Indemnified
     Party agrees, at the Indemnifying Party's expense, to cooperate with the
     Indemnifying Party and its counsel in contesting any claim or demand that
     the Indemnifying Party elects to contest, or, if appropriate and related to
     the claim in question, in making any counterclaim against the Person
     asserting the third party claim or demand, or any cross-complaint against
     any Person. No claim as to which indemnification is sought under this
     Agreement may be settled without the consent of the Indemnifying Party,
     except as provided in Section 12.4(a).

                (c) If any Indemnified Party should have a claim against the
     Indemnifying Party hereunder that does not involve a claim or demand being
     asserted against or sought to be collected from it by a third party, the
     Indemnified Party shall send a Claim Notice with respect to such claim to
     the Indemnifying Party. If the Indemnifying Party disputes such claim, such
     dispute shall be resolved by litigation in a state or federal court in
     Indiana, in accordance with the terms of Section 16.9.

          12.5  Costs.  If any legal action or other proceeding is brought for
                -----
the enforcement or interpretation of any of the rights or provisions of this
Agreement (including the indemnification provision), or because of an alleged
dispute, breach, default or misrepresentation in connection with any of the
provisions of this Agreement, the successful or prevailing party shall be
entitled to recover reasonable attorneys' fees and all other costs and expenses
incurred in that action or proceeding, in addition to any other relief to which
it may be entitled.

       ARTICLE 13. SURVIVAL OF COVENANTS, AGREEMENTS, REPRESENTATIONS AND
       ------------------------------------------------------------------
                           WARRANTIES; RIGHT OF OFFSET
                          ---------------------------

          13.1  Survival.  All representations, warranties, covenants and
                --------
agreements made by the parties each to the other in this Agreement or pursuant
hereto in any certificate, instrument or document shall survive the consummation
of the transactions contemplated by this Agreement, and may be fully and
completely relied upon by BUYER and by SELLERS and the Shareholders, as the case
may be, notwithstanding any investigation heretofore or hereafter made by such
party or on behalf of any of them for a period of two (2) years from the Closing
Date; provided, however, that with respect to any demand or claim as to which
notice has been given
<PAGE>

within said period, the representations, warranties, covenants and agreements
with respect thereto shall survive until finally resolved by agreement or in the
courts; and provided, further, that the foregoing shall not apply to any
agreement that is to be entered into at Closing pursuant to the terms hereof,
the terms of which shall survive until fully performed in accordance with such
agreement.

          13.2  Right of Offset.  BUYER shall have the right to set off any
                ---------------
obligation it has under this Agreement, the Put Agreement (Exhibit F), the LLC
Agreement (Exhibit E) or otherwise to any SELLER or any Shareholder against any
obligation any SELLER or any Shareholder has to BUYER under this Agreement or
otherwise; provided, however, BUYER shall have no right of set off with respect
to amounts to be paid under Section 4.3 hereof; and provided further, any such
obligation of a SELLER or a Shareholder that is not represented by a final
judgment or as to which such SELLER or Shareholder has agreed to an offset, such
right of offset shall be limited to the preferred interest distribution payable
with respect to the Preferred Interest (or any interest substituted therefor)
issued pursuant to Section 4.3(b) above. In the event any offset (or any part
thereof) is ultimately determined to have been in excess of amounts owing by the
SELLERS or the Shareholders to BUYER, then the SELLERS and the Shareholders
shall be entitled to recover from BUYER (i) interest on such excess from the
date of the offset computed at the then prevailing prime interest rate as
published in The Wall Street Journal from time to time and (ii) reasonable
             -----------------------
attorneys' fees. BUYER further agrees that in the event that any claim BUYER has
against SELLERS or any Shareholder that is represented by a final judgment or as
to which such SELLER or Shareholder has agreed to offset, then BUYER shall first
offset the amount of such claim against the capital account of such SELLER or
Shareholder before seeking payment of such claim.

          Except as otherwise set forth herein, each party agrees to pay,

incident to the preparation and execution of this Agreement and performance of
their respective obligations hereunder, whether or not the transactions

                            -----------------------

          15.1  Termination.  This Agreement may be terminated at any time prior
                -----------
to the Closing:

                (a)  By agreement of all of the parties hereto;

                (b) By either BUYER or any SELLER if the Closing has not taken
     place on or before October 31, 2000 (the "Cut-Off Date"); provided that the
     right to terminate this Agreement under this Section 15.1(b) shall not be
     available to any party whose failure to fulfill any obligation under this
     Agreement has been the cause of, or results in, the failure of the Closing
     to occur within such period;

                (c)  By BUYER pursuant to Section 9.11 hereof;
<PAGE>

                (d) By BUYER or any SELLER, as the case may be, (i) if any of
     the conditions precedent to the performance of the obligations of the party
     giving notice of termination shall not have been fulfilled and cannot be
     fulfilled on or prior to the Cut-Off Date and shall not have been waived in
     writing by such party, or (ii) if a default shall be made by the other
     party in observance or in the due and timely performance of any of the
     covenants and agreements herein contained that cannot be cured on or prior
     to the Cut-Off Date and shall not have been waived in writing by such
     party; or (iii) if there exists an inaccuracy, failure or breach of a
     warranty or representation set forth herein or in any other agreement or
     instrument executed pursuant hereto that has not been waived in writing by
     the party for whose benefit such warranty or representation was made or
     given; and

                (e) At the option of BUYER or any SELLER, if any action or
     proceeding shall have been instituted and remain pending before a court or
     other governmental body by any federal, state or local government or agency
     thereof to restrain or prohibit the consummation of the transactions
     contemplated by this Agreement, or if any federal, state or local
     government or agency thereof shall have threatened to institute any
     proceeding before a court or other governmental body to restrain the
     consummation of such transactions or to force divestiture, provided that
     neither party shall have the option to terminate this Agreement as provided
     herein after any such action or notice by any federal, state or local
     government or governmental agency or other Person shall be withdrawn or
     settled.

          15.2  No Liability.  Except in the event of a termination of this
                ------------
Agreement pursuant to Section 15.1(d)(ii) or (iii), there shall be no liability
on the parties hereto or any of their respective members, managers, officers,
directors, shareholders or Affiliates as a result thereof under this Agreement.
A termination under Section 15.1(d)(ii) or (iii) hereof shall not prejudice any
claim for damages which any party may have hereunder or in law or in equity as a
consequence of any matter giving rise to a termination of the Agreement under
Section 15.1(d)(ii) or (iii) hereof. BUYER and SELLERS shall have the right to
specific performance if the Agreement is not otherwise terminated in accordance
with the terms hereof.

          15.3  Notice.  BUYER may exercise its right of termination of this
                ------
Agreement only by delivering written notice to that effect to SELLERS, provided
that such notice is received by SELLERS prior to the Closing. Any SELLER may
exercise its right of termination of this Agreement only by delivering written
notice to that effect to BUYER, provided that such notice is received by BUYER
prior to the Closing.

          16.2  Parties in Interest and Assignment.
                ----------------------------------

                (a) This Agreement is binding upon and is for the benefit of the
     parties hereto and their respective successors and assigns. Except as
     expressly provided herein, nothing in this Agreement, express or implied,
     is intended to confer on any Person other than the parties hereto or their
     respective successors and assigns any rights, remedies or obligations or
     liabilities under or by reason of this Agreement.

                (b) Except as provided in Section 16.2(c) below, neither this
     Agreement nor any of the rights or duties of any party hereto may be
     transferred or assigned to any Person except by a written agreement
     executed by all of the parties hereto.

                (c) Notwithstanding the above, BUYER may transfer and assign all
     or any portion of its rights under this Agreement for purposes of or in
     connection with the IPO, but any such assignment shall not relieve BUYER
     from any of its obligations hereunder. Notwithstanding the above, each
     SELLER may assign its rights under this Agreement to the Shareholders in
     the event such SELLER is liquidated and/or dissolved in accordance with
     applicable law. Any assignee hereunder shall assume all of the assignor's
     obligations hereunder, including obligations under Article 12.

          16.3  Modification.  This Agreement may not be amended or modified
                ------------
except by a writing signed by an authorized representative of the party against
whom enforcement of the change is sought. No waiver of the performance or breach
of, or default under, any condition or obligation hereof shall be deemed to be a
waiver of any other performance, or breach of, or default under the same or any
other condition or obligation of this Agreement.
<PAGE>

          16.4  Waiver.  Each party hereto may, by written notice to the other

party hereto: (a) extend the time for the performance of any of the obligations
or other actions of such other party under this Agreement; (b) waive any
inaccuracies in the representations or warranties of such other party contained
in this Agreement or in any document delivered pursuant to this Agreement; (c)
waive compliance by such other party with any of the conditions or covenants of
the other contained in this Agreement; or (d) waive or modify performance of any
of the obligations of such other party under this Agreement. Except as provided
in the preceding sentence, no action taken by or on behalf of any party,
including, without limitation, any investigation by or on behalf of such party,
shall be deemed to constitute a waiver by the party taking such action of
compliance with any representations, warranties, covenants or agreements
contained in this Agreement.

          16.5  Entire Agreement.  This Agreement embodies the entire agreement
                ----------------
between the parties hereto and there are no agreements, representations or
warranties between the parties other than those set forth or provided herein.
All Exhibits and Schedules called for by this Agreement and delivered to the
parties shall be considered a part hereof with the same force and effect as if
the same had been specifically set forth in this Agreement. BUYER acknowledges

information and documents from SELLERS, in each case with respect to the
Business and Assets of SELLERS.

          16.6  Execution in Multiple Originals.  This Agreement may be executed
                -------------------------------

reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

          16.8  Invalid Provisions.  If any provision of this Agreement is held
                ------------------
to be illegal, invalid or unenforceable under any present or future law, and if
the rights or obligations of any party hereto under this Agreement will not be
materially and adversely affected thereby, (a) such provision will be fully
severable; (b) this Agreement will be construed and enforced as if such illegal,
invalid or unenforceable provision had never comprised a part hereof; and (c)
the remaining provisions of this Agreement will remain in full force and effect
and will not be affected by the illegal, invalid or unenforceable provision or
by its severance herefrom.

          16.9  Governing Law; Forum.  This Agreement shall be governed by and
                --------------------
construed, interpreted and enforced in accordance with the laws of the State of

     United States District Court located in the Northern District of the State
     of Indiana;

     party's principal office or principal residence is located.
