AGREEMENT

        In consideration of the agreements contained herein, the Company, Southwest, and Monette agree as follows:

        1.    General Transfer Restrictions.

            (a)   Monette may not, without the consent of Southwest, which consent may be withheld in its sole discretion, sell, transfer, assign, pledge, hypothecate, or otherwise dispose of any Common Stock or any interest (including beneficial interest) therein except as expressly permitted under this Agreement.

            (b)   Southwest may, at any time in its sole discretion, sell, transfer, assign, pledge or otherwise dispose of any Common Stock or any interest (including beneficial interest) therein.

        2.    Call Option.

            (a)   Southwest may, at its sole option, at any time after the fifth (5th) anniversary of the date hereof, require Monette (and his successors or assigns) to sell to Southwest all, but not less than all, of the Common Stock owned by Monette (and his successors or assigns).

            (b)   Without limiting in any way the rights of Southwest set forth in Section 2(a) above, Southwest may, at its sole option, at any time upon, and for a period of five (5) years after (i) the termination for any reason of Monette's employment with the Southwest or any of its affiliates, (ii) a four (4) month continuous period of physical or mental illness of Monette during which time Monette is disabled, (iii) the commencement of bankruptcy or insolvency proceedings by Monette individually, or (iv) Monette's death, require Monette and his successors and assigns to sell to Southwest all, but not less than all, of the Common Stock owned by Monette and his successors and assigns.

            (c)   Calculation of Consideration.

              (i)    If Southwest exercises its call option pursuant to this Section 2 prior to the completion of four (4) consecutive fiscal quarters of the Company (the first of such fiscal


      quarters shall commence on October 1, 2001), the purchase price for the Common Stock owned by Monette pursuant to the provisions of this Section 2 shall be $1,000,000.00. If Southwest exercises its call option pursuant to this Section 2 at or following the completion of four (4) consecutive fiscal quarters of the Company (the first of such fiscal quarters shall commence on October 1, 2001), the purchase price for the Common Stock owned by Monette shall be the greater of (i) $1,000,000.00, or (ii) the product of (x) Company EBITA multiplied by five, multiplied by (y) 0.1. As used herein, "Company EBITA" shall mean the net income of the Company during the four (4) completed fiscal quarters immediately preceding the exercise of the call option by Southwest pursuant to this Section 2, plus to the extent such charges are deducted in determining net income, (i) any interest on Indebtedness attributable to the Company, (ii) all income Taxes attributable to the Company, and (iii) any amortization of goodwill and other intangibles attributable to the Company, all as calculated and determined in accordance with United States generally accepted accounting principles, consistently applied ("GAAP"), and to the extent consistent with GAAP, in a manner consistent with the past accounting practices of Southwest. Prior to the sale, transfer, or delivery by Southwest to the Company of any executory contracts by and between ECO Resources, Inc., a wholly-owned subsidiary of Southwest, and certain unrelated third parties (each, an "ECO Contract"), each of the Company and Monette shall agree in writing as to the amount of the target EBITA with respect to the ECO Contract (the "Target EBITA"). To the extent that any Company EBITA is attributable to any ECO Contract, there shall be deducted from the calculation of Company EBITA that amount of the Target EBITA with respect to each such ECO Contract. Any calculation of Company EBITA shall be performed and completed by Southwest and the Company, and the results of such calculation shall be delivered to Monette. If Monette does not object in writing to Southwest and the Company to the results of such calculation within ten (10) days of such delivery to Monette, the results of such calculation shall be final and binding upon Monette. In the event that Monette does object to the results of the calculation of Company EBITA, then the parties shall resolve their dispute in accordance with Section 9(n) below. As used herein, "Indebtedness" shall mean (i) all indebtedness for borrowed money or for the deferred purchase price of property or services (including, without limitation, reimbursement and all other obligations with respect to surety bonds, letters of credit and bankers' acceptances, whether or not matured), including the current portion of such indebtedness, and (ii) all obligations evidenced by notes, bonds, debentures or similar instruments. As used herein, "Taxes" shall mean all tax (including income tax, capital gains tax, value added tax, sales tax, property tax, gift tax or estate tax), levy assessment, tariff, duty (including customs duty), deficiency or other fee and any related charge or amount (including fine, penalty and interest) imposed, assessed or collected by or under the authority of any governmental or regulatory body.

              (ii)   For the purposes of determining Company EBITA, Company EBITA shall include a deduction for an amount equal to fifty percent (50%) of any amount paid to Monette by the Company in accordance with the management performance award program of Southwest, as defined in and pursuant to the terms of that certain Employment Agreement by and between Southwest and Monette dated as of August 31, 2001.

              (iii)  For the purposes of determining Company EBITA, Company EBITA may include a reasonable deduction for any direct or indirect allocations from Southwest with respect to the Company. Direct allocations from Southwest with respect to the Company would be for expenses that were paid, or reimbursed, by Southwest on behalf of the Company (examples include, but are not limited to, medical insurance payments, comprehensive liability insurance payments, direct reimbursements for payroll processing services, and payments for legal and accounting expenses relating to Company operations). Indirect allocations from Southwest with respect to the Company would be for Southwest expenses that benefit Southwest that

2



      may benefit the Company and the other subsidiaries of Southwest (examples include, but are not limited to, public company expenses, and expenses associated with corporate offices). For purposes of determining Company EBITA, any indirect allocations of Southwest relating to the Company will be reasonably made on the same basis as any indirect allocation of Southwest relating to ECO Resources, Inc., a Texas corporation and subsidiary of Southwest.

            (d)   If Southwest exercises its call option to purchase the Company Stock owned by Monette (and his successors or assigns) pursuant to this Section 2, Southwest shall deliver written notice (the "Call Notice") to Monette (or his successors or assigns). The Call Notice shall set forth the number of shares of Common Stock to be acquired from Monette (and his successors or assigns), the aggregate consideration to be paid for such shares, and the time and place for the closing of the transaction. Southwest will be entitled to receive customary representations and warranties from Monette (and his successors and assigns) regarding the good title to such Common Stock, free from any liens, encumbrances or restrictions on sale.

            (e)   The closing of the call option set forth in this Section 2 shall take place on the date designated by Southwest in the Call Notice, which date shall not be more than thirty (30) days and not less than ten (10) days after the delivery of the Call Notice. Southwest (or its assignee(s)) shall pay for the Common Stock owned by Monette (or his successors and assigns) by delivery of cash or other immediately available funds in an amount equal to the purchase price of the Common Stock being acquired; provided that Southwest shall, at the direction of Monette, pay up to one hundred percent (100%) of the purchase price for the Common Stock purchased by Southwest by delivery of a promissory note on terms mutually agreed upon by Southwest and Monette, or in shares of common stock of Southwest.

            (f)    In the event that the Common Stock owned by Monette (and his successors and assigns) is purchased by Southwest pursuant to this Section 2, each of Southwest, Monette, and their successors and assigns, will take all steps necessary and desirable to obtain all required third-party, governmental and regulatory consents and approvals and take all other actions necessary and desirable to facilitate the consummation of such purchase in a timely manner.

        3.    Put Option.

            (a)   Monette may, at his sole option, at any time after the second (2nd) anniversary of the date hereof, require Southwest (and its successors or assigns) to purchase from Monette all, but not less than all, of the Common Stock owned by Monette (and his successors or assigns).

            (b)   Calculation of Consideration.

              (i)    The purchase price for the Common Stock owned by Monette upon exercise by Monette of his put option pursuant to this Section 3 shall be the greater of (i) $1,000,000.00 or (ii) the product of (x) Company EBITA multiplied by five, multiplied by (y) 0.1. As used herein, "Company EBITA" shall mean the net income of the Company during the four (4) completed fiscal quarters immediately preceding the exercise of the put option by Monette pursuant to this Section 3, plus to the extent such charges are deducted in determining net income, (i) any interest on Indebtedness attributable to the Company, (ii) all income Taxes attributable to the Company, and (iii) any amortization of goodwill and other intangibles attributable to the Company, all as calculated and determined in accordance with United States generally accepted accounting principles, consistently applied ("GAAP"), and to the extent consistent with GAAP, in a manner consistent with the past accounting practices of Southwest. Prior to the sale, transfer, or delivery by Southwest to the Company of any executory contracts by and between ECO Resources, Inc., a wholly-owned subsidiary of Southwest, and certain unrelated third parties (each, an "ECO Contract"), each of the Company and Monette shall agree in writing as to the amount of the target EBITA with

3


      respect to the ECO Contract (the "Target EBITA"). To the extent that any Company EBITA is attributable to any ECO Contract, there shall be deducted from the calculation of Company EBITA that amount of the Target EBITA with respect to each such ECO Contract. Any calculation of Company EBITA shall be performed and completed by Southwest and the Company, and the results of such calculation shall be delivered to Monette. If Monette does not object in writing to Southwest and the Company to the results of such calculation within ten (10) days of such delivery to Monette, the results of such calculation shall be final and binding upon Monette. In the event that Monette does object to the results of the calculation of Company EBITA, then the parties shall resolve their dispute in accordance with Section 9(n) below. As used herein, "Indebtedness" shall mean (i) all indebtedness for borrowed money or for the deferred purchase price of property or services (including, without limitation, reimbursement and all other obligations with respect to surety bonds, letters of credit and bankers' acceptances, whether or not matured), including the current portion of such indebtedness, and (ii) all obligations evidenced by notes, bonds, debentures or similar instruments. As used herein, "Taxes" shall mean all tax (including income tax, capital gains tax, value added tax, sales tax, property tax, gift tax or estate tax), levy assessment, tariff, duty (including customs duty), deficiency or other fee and any related charge or amount (including fine, penalty and interest) imposed, assessed or collected by or under the authority of any governmental or regulatory body.

              (ii)   For the purposes of determining Company EBITA, Company EBITA shall include a deduction for an amount equal to fifty percent (50%) of any amount paid to Monette by the Company in accordance with the management performance award program of Southwest, as defined in and pursuant to the terms of that certain Employment Agreement by and between Southwest and Monette dated as of August 31, 2001.

              (iii)  For the purposes of determining Company EBITA, Company EBITA may include a reasonable deduction for any direct or indirect allocations from Southwest with respect to the Company. Direct allocations from Southwest with respect to the Company would be for expenses that were paid, or reimbursed, by Southwest on behalf of the Company (examples include, but are not limited to, medical insurance payments, comprehensive liability insurance payments, direct reimbursements for payroll processing services, and payments for legal and accounting expenses relating to Company operations). Indirect allocations from Southwest with respect to the Company would be for Southwest expenses that benefit Southwest that may benefit the Company and the other subsidiaries of Southwest (examples include, but are not limited to, public company expenses, and expenses associated with corporate offices). For purposes of determining Company EBITA, any indirect allocations of Southwest relating to the Company will be reasonably made on the same basis as any indirect allocation of Southwest relating to ECO Resources, Inc., a Texas corporation and subsidiary of Southwest.

            (c)   If Monette exercises his put option to cause Southwest to purchase the Company Stock owned by Monette (and his successors or assigns) pursuant to this Section 3, Monette shall deliver written notice (the "Put Notice") to Southwest (or its successors or assigns).

Southwest (or its assignee(s)) shall

            (e)   In the event that the Common Stock owned by Monette (and his successors and assigns) is purchased by Southwest pursuant to this Section 3, each of Southwest, Monette, and their successors and assigns, will take all steps necessary and desirable to obtain all required third-party, governmental and regulatory consents and approvals and take all other actions necessary and desirable to facilitate the consummation of such purchase in a timely manner.

    corporate reorganization, or any other form of recapitalization, consolidation, merger, stock split or stock dividend, or which are acquired by Southwest or Monette in any other manner.

            (m)  Approvals and Consents. Southwest and Monette hereby agree, for themselves, their successors, heirs and legal representatives, to vote at shareholders' and directors' meetings of the Company (as the case may be), to prepare, execute and deliver or cause to be prepared, executed and delivered such further instruments and documents, to take such other actions and to adopt such provisions of the Articles of Incorporation and Bylaws of the Company as may be reasonably required to more effectively carry out the intent and purposes of this Agreement and the transactions contemplated hereby. They further agree to cause the Company to do the same.

            (n)   Arbitration. Except as otherwise set forth in this Agreement, all disputes arising out of or under this Agreement shall be settled by arbitration in a location in the city of Atlanta, Georgia mutually acceptable to the parties before a single arbitrator pursuant to the rules of the American Arbitration Association. Arbitration may be commenced at any time by any of the parties by giving written notice to each other than such dispute has been referred to arbitration under this Section 9(n). The arbitrator shall be selected by the joint agreement of the parties, but if they do not so agree within twenty (20) days after the date of receipt of the notice referred to above, the selection shall be made pursuant to the rules from the panels of arbitrators maintained by the American Arbitration Association. In any such arbitration, the Georgia Rules of Evidence and the Georgia Rules of Civil Procedure shall apply. Any award rendered by the arbitrator shall be conclusive and binding upon the parties hereto; provided, however, that any such award shall be accompanied by a written opinion of the arbitrator giving the reason for the award. This provision for arbitration shall be specifically enforceable by the parties and the decision of the arbitrator in accordance herewith shall be final and binding and there shall be no right of appeal therefrom. The arbitrator shall assess, as part of his award to the prevailing party, all or such part as the arbitrator deems proper of the arbitration expenses of the prevailing party (including reasonable attorneys' fees) and of the arbitrator against the party that is unsuccessful in such claim, defense or objection. The parties shall have the right to seek enforcement of any such award provided pursuant to this Section 9(n) pursuant to Section 9(h) and Section 9(i) of this Agreement.
