                  Agreement between the Company and the State of Missouri
                  (including any increase in the Company's or the Buyer Parties'

                  imposed on the Company by the Settlement Agreement);

                  (2) 20,619 shares shall be retained and held back by the Buyer
                  Parties to reimburse and compensate the Buyer Parties and the

                  any delay in obtaining, all necessary approvals, permits,
                  consents and licenses of governmental authorities for the

                  closing down the landfill and/or transferring operations to a
                  temporary facility; and

                  (3) 51,546 shares shall be retained and held back by the Buyer
                  Parties to satisfy all amounts owing in respect of the Liens
                  (as defined in Section 3.14 hereof) on the Company's Real
                  Property (as defined in Section 3.14 hereof) reflected on
                  Schedule 2.1(b) attached hereto, and to pay any related costs
                  and expenses the Buyer Parties may incur in obtaining the full
                  release and removal from the applicable real property records
                  of all such Liens. The Parties acknowledge and agree that the
                  Sellers are jointly and severally obligated to obtain releases
                  of all such Liens and clear them from the real property
                  records applicable to the Company's Real Property and shall
                  use their respective best efforts to do so as soon as possible
                  following the Closing. Notwithstanding the foregoing, if
                  within ninety (90) days after the Closing the Sellers shall
                  not have provided the Buyer Parties with written evidence
                  satisfactory to the Buyer Parties in their reasonable
                  discretion that all of the Liens reflected on Schedule 2.1(b)
                  have been fully released and cleared from the real property
                  records applicable to the Company's Real Property, the Buyer
                  Parties may take all such actions as the Buyer Parties, in
                  their reasonable discretion, deem necessary to satisfy in full
                  and obtain releases of the Company and the Company's Real
                  Property from any and all such Liens then remaining of record,
                  and all of the obligations to which such Liens relate, as well
                  as all costs and expenses incurred by the Buyer Parties in
                  connection with satisfying and obtaining releases from such
                  Liens shall be satisfied first out of the Stock Holdback.

            (c) Release of Stock Holdback. With respect to the Losses,
            obligations, costs and expenses described in Sections 2.1(b)(1) and
            2.1(b)(2) above, and so as to reimburse and compensate Parent, Buyer
            and the Company for such amounts, the Parties agree that the Buyer
            Parties shall give written notice of such Losses, obligations, costs
            and expenses to the Sellers reasonably promptly following the
            accrual of such Losses, obligations, costs and expenses, and that
            the Buyer Parties

                                       7



            shall be relieved of any obligation to deliver and be entitled to
            cancel, and Sellers shall forfeit any right to receive, that number
            of shares of the Stock Holdback with a market value (which, for
            purposes of this Section 2.1(c), shall be equal to the closing
            market price for shares of Parent Common Stock on the day on which
            the Buyer Parties deliver such written notice to the Sellers or, if
            such day is not a trading day, the next trading day immediately
            following such day) equal to such amounts (as reasonably estimated
            by the Buyer Parties). With respect to the Losses, obligations,
            costs and expenses described in Section 2.1(b)(3), and so as to
            reimburse and compensate Parent, Buyer and the Company for such
            amounts, the Parties agree that the Buyer Parties shall be relieved
            of any obligation to deliver and be entitled to cancel, and Sellers
            shall forfeit any right to receive, that number of shares of the
            Stock Holdback as set forth in clause (z) below. To the extent that
            the value of the shares of Parent Common Stock in the Stock Holdback
            are insufficient to pay such Losses or to fully pay, satisfy and
            reimburse such obligations, costs and expenses, any remaining
            amounts shall be paid by the Sellers. Shares of Parent Common Stock
            remaining of the Stock Holdback, if any, shall be paid to the
            Sellers according to the percentages or other formula set forth in
            Schedule 2.1(c) hereto as follows: (x) with respect to the shares
            held back pursuant to Section 2.1(b)(1) above, such shares shall be
            released to Sellers upon the entering of a final Settlement
            Agreement between the Company and the State of Missouri, (y) with

      3.3   MEMBERSHIP INTERESTS OF THE COMPANY. The authorized membership
            interests of the Company are shown on Schedule 3.3. All of the
            Company's issued and outstanding membership interests have been duly
            authorized and validly issued, are fully paid and nonassessable, are
            owned of record and beneficially by the Sellers in the amounts set
            forth in Schedule 3.3, and are free and clear of all liens,
            encumbrances and claims of every kind. All such membership interests
            were offered, issued, sold and delivered in compliance with all
            applicable state and federal laws concerning the issuance of

            refusal, option, warrant, call, conversion right or commitment of

            foregoing, there is no valid basis upon which any person (other than
            the Sellers) may claim to be in any way the record or beneficial
            owner of, or to be entitled to acquire (of record or beneficially),
            any membership interest or other security of the Company, and no
            person has made or, to any Seller Party's respective knowledge,
            threatened to make any such claim. In addition, the Company has no
            obligation (contingent or otherwise) to purchase, redeem or
            otherwise acquire any of its membership interests or any interests
            therein or to pay any dividend or make any distribution in respect
            thereof.

            (b) The Company does not maintain any Pension Plan or Benefit Plan
            intended to be a tax qualified plan described Section 401(a) of the
            Code, and no such plan is or has been subject to the minimum funding
            rules of Code Section 412 or ERISA Section 302, or the plan
            termination insurance provisions of Title IV of ERISA.

            (c) Each of the Pension Plans, Welfare Plans and Benefit Plans
            sponsored by, and each of the benefit plans formerly sponsored by,
            the Company: (i) has been in material compliance with all reporting
            and disclosure requirements of (A) Part 1 or Subtitle B of Title I
            of ERISA, if applicable, or (B) other applicable law, (ii)

            subject the Company or any of its subsidiaries to the payment of any
            material penalty, interest, tax or other obligation, nor is there
            any basis for any imposition of any such liability, and (v) has been
            maintained in all respects in material compliance with the
            applicable requirements of ERISA, the Code and other applicable law
            not otherwise covered hereunder so as not to give rise to any
            material liabilities to the Company.

            (d) There are no voluntary employee benefit associations maintained
            by the Company and intended to be exempt from federal income tax

            provisions in any Pension Plan, Welfare Plan or Benefit Plan
            sponsored by the Company. The consummation of any transaction
            contemplated by this Agreement will not result in any: (i) payment
            (whether of severance pay or otherwise) becoming due from the
            Company to any of its officers, employees, former employees or
            directors or to the trustee under any "rabbi trust" or similar

            payment" within the meaning of Section 280G of the Code.

            (f) The Company does not provide any material post-retirement
            medical, health, disability or death protection coverage or
            contribute to or maintain any employee welfare benefit plan which
            provides for medical, health, disability or death benefit coverage
            following termination of employment by any officer, director or
            employee except as is required by Section 4980B(f) of the Code or
            other applicable statute, nor has the Company made any
            representations, agreements, covenants or commitments to provide
            that coverage.

            (g) With respect to any Welfare Plan of the Company, (i) each such
            Welfare Plan that is a group health plan, as such term is defined in
            Section 5000(b)(1) of the Code, complies in all material respects
            with any applicable requirements of Part 6 of Title I of ERISA and
            Section 4980B(f) of the Code and (ii) each such Welfare Plan
            (including any such plan covering retirees or other former
            employees) may be amended or terminated with respect to health
            benefits without material liability to the Company on or at any time
            after the Closing Date.

                                      16



            (h) All contributions required by law or by a collective bargaining
            or other agreement to be made under any Pension Plan, Welfare Plan
            or Benefit Plan of the Company with respect to all periods through
            the Closing Date, including a pro rata share of contributions due
            for the current plan year, will have been made by such date or
            provided for by adequate reserves by the Company. No changes in
            contribution rates or benefit levels have been implemented or
            negotiated (but not yet implemented), with respect to any Pension
            Plan, Welfare Plan or Benefit Plan of the Company since the date on

            damages, judgments, settlement costs, expenses, costs, or any other
            liability or liabilities of any nature whatsoever arising out of or
            in any manner relating to any Pension Plan, Welfare Plan or Benefit
            Plan (including but not limited to employee benefit plans such as

                                      27



            Parties' investigation and representation by counsel shall not limit
            or diminish the Buyer Parties' reliance upon the representations,
            warranties and covenants set forth in this Agreement.

5.    COVENANTS OF THE PARTIES

      5.1   NOTICES AND APPROVALS. The Seller Parties shall timely give all
            notices and request all approvals and assignments that may be
            required under applicable law or any of the permits, agreements,
            orders or other instruments to which the Company is bound, in
            connection with the contemplated transaction.

      5.2   ACCESS TO INFORMATION.

            (a) On and after the date of this Agreement, the Seller Parties will
            furnish to Parent such information with respect to the Company as
            Parent shall reasonably request. Without limitation of the
            foregoing, the Seller Parties shall (i) afford to Parent and its
            officers, employees, accountants, consultants, counsel and other
            authorized representatives reasonable access, throughout the period
            prior to the earlier of the Closing Date or the date this Agreement
            is terminated, to the Company's plants, properties (including,
            without limitation, the Real Property), and books and records
            relating to the Company; (ii) use its best efforts to cause its
            representatives to furnish to Parent and its authorized
            representatives such additional financial and operating data and
            other information as to the Company as Parent or its duly authorized
            representatives may from time to time reasonably request; and (iii)
            afford Parent and its representatives reasonable access, throughout
            the period prior to the Closing Date, to the Company's present and
            potential customers relating to the Business, such that Parent may
            conduct such due diligence investigation relating to customer
            relations as Parent deems reasonably necessary or appropriate. The
            Seller Parties hereby release, discharge and hold harmless each of
            Parent and Buyer, any affiliate or subsidiary of Parent or Buyer,
            and any officer, director, shareholder, employee, agent, attorney,
            joint venturer, partner, servant, consultant, representative,
            trustee, successor or assign of Parent or Buyer or of any of its
            affiliates or subsidiaries, from all liability or claims by reason
            of any such access or contact referred to in this Section 5.2,
            except for any misuse by Parent or Buyer of such information.

            (b) Parent and Buyer covenant and agree that, prior to the Closing,
            all due diligence materials will be used solely for the purposes of
            assessing the Company in connection with the Buyer Parties' possible
            acquisition thereof pursuant to this Agreement, and that any other
            use shall be strictly prohibited; provided, however, that following
            the Closing, Parent and Buyer may use all such materials for any
            purposes in their sole discretion.

      5.3   COPIES OF AGREEMENTS. True and correct copies of all agreements
            (including copies of all insurance agreements) relating to the
            Company shall be delivered to Parent on the Closing Date.

      5.4   RECORDS. The Seller Parties shall retain and maintain the records of
            the Company in the normal course of business.

      5.5   TAXES.

            (a) From and after the Closing, upon written notice by Parent, the
            Sellers shall pay to Parent or, at the Sellers' option, to the
            Internal Revenue Service and/or federal, state or local, or foreign
            Tax Authorities, as appropriate, and shall otherwise indemnify, save
            and hold Parent, Buyer and the Company harmless from and against all
            demands, claims, actions, causes of action, assessments, losses,
            damages, liabilities, costs and expenses asserted against, resulting
            to, imposed upon or incurred by Parent, Buyer or the Company with
            respect to the Company which directly or indirectly relate to or
            arise out of any Tax years (including partial years) on or prior to
            the Closing Date with respect to any deficiencies assessed by the
            Internal Revenue Service and/or federal, state and local, and
            foreign Tax Authorities for any federal, state or local, or foreign
            income, sales, ad valorem or other tax liability arising on or prior
            to the Closing Date. The Sellers shall also be obligated under this
            Section 5.5 for any assessment caused by any act or failure to act
            on the part of any Seller after the date of this Agreement. Nothing
            contained herein shall affect the Sellers' right to contest any Tax
            liability in the manner set forth in the applicable statute.

            (b) For purposes of this Agreement, Taxes of the Company incurred
            with respect to a Taxable period that includes but does not end on
            the Closing Date, shall be allocated to the portion of the period
            ending on the Closing Date (A) except as provided in (B) and (C)
            below, to the extent feasible, on a specific identification basis,
            according to the date of the event or transaction giving rise to the
            Tax, and (B) except as provided in (C) below, with respect to
            periodically assessed ad valorem Taxes and Taxes not otherwise
            feasibly allocable to specific transactions or events, in proportion
            to the number of days in such period occurring before the Closing
            Date compared to the total number of days in such period, and (C) in
            the case of any Tax based upon or related to income or receipts, in
            an amount equal to the Tax which would be payable if the relevant
            taxable period ended on the Closing Date (for the elimination of
            doubt, Taxes incurred by reason of the transactions contemplated by
            this Agreement shall be allocated to the portion of the period
            ending on the Closing Date). Any credits relating to a Taxable
            period that begins before and ends after the Closing Date shall be
            taken into account as though the relevant Taxable period ended on
            the Closing Date.

            (c) Notwithstanding any other provision of this Agreement, including
            this Section 5.5, the Sellers shall be liable for and shall pay all
            Taxes arising from, or related to, the transactions contemplated by
            this Agreement, whether such Taxes are incurred by the Sellers, the
            Company, Parent or Buyer.

      5.6   COMPLIANCE WITH LAWS. The Seller Parties and the Buyer Parties shall
            comply with all applicable laws as may be required for the sale and
            transfer of the

                                      29



            Membership Interests and for the performance of all other acts and
            things contemplated by this Agreement.

      5.7   NOTICE OF BREACH. In the event of, and promptly after, the taking of
            any action or occurrence or threatened occurrence of any event, the
            taking of which would make untrue, inaccurate or misleading, or
            would constitute or result in a breach or violation of, any of the
            representations, warranties, covenants or agreements of a party set
            forth herein, or would, if it had occurred prior to the date hereof,
            make any representation or warranty made by such party herein
            untrue, inaccurate or misleading, such party shall promptly give
            written notice thereof to the other party.

      5.8   REASONABLE EFFORTS. Each of the parties hereto agrees to use
            reasonable efforts to take or cause to be taken all actions, and to
            do or cause to be done all things reasonably necessary, proper or
            advisable to satisfy promptly all conditions required hereby to be
            satisfied by such party in order to consummate and make effective
            the transactions contemplated hereby.

      5.9   NOTIFICATION. The Seller Parties shall notify the Buyer Parties, and
            the Buyer Parties shall immediately notify the Seller Parties, of
            any litigation, arbitration or administrative proceeding pending or,
            to any of their knowledge, threatened against the Seller Parties or
            the Buyer Parties, as the case may be, which challenges the
            transactions contemplated hereby.

      5.10  INJUNCTIONS. If any United States, state or foreign court having
            jurisdiction over any party issues or otherwise promulgates any
            injunction, decree or similar order prior to the Closing which
            prohibits the consummation of the transactions contemplated hereby,
            the parties will use their respective reasonable efforts to have
            such injunction dissolved or otherwise eliminated as promptly as
            possible and, prior to or after the Closing, to pursue the
            underlying litigation diligently and in good faith.

      5.11  AUDIT. Parent, at its own cost and expense, will engage external
            auditors to audit the Company's financial records (including up to
            three years of historical data). The Sellers shall fully cooperate
            with such audit and will assist in the completion of such audit,
            including, without limitation, by providing, executing and
            acknowledging all such documents that are necessary to complete the
            audit (including having the Company's financial records converted,
            if necessary and for Parent's use only, to accrual based accounting
            financials in accordance with GAAP), and by making any
            representations regarding the Business and the Company's financial
            records, as may be reasonably requested by Parent or the external
            auditors.

      5.12  TAX RETURNS. With respect to any Tax Return, any audit or other
            examination by any governmental authority after the Closing Date
            which includes any period ending on or before the Closing Date,
            Parent shall consult with the Sellers and the Sellers shall provide
            Parent such assistance as necessary in connection with the

                                      30



            preparation of such Tax Return, audit or other examination or any
            judicial or administrative proceeding relating to liability for
            Taxes, and the Sellers will provide Parent with any records or
            information related to the Company that may be relevant to any of
            the foregoing. Parent shall file any Tax Return necessary with
            regard to the transactions contemplated by this Agreement.

      5.13  COOPERATION AND TRANSITION.

            (a) The Parties shall cooperate in the transition of the Company and
            the Business to the Buyer Parties, including by transferring the
            books, records and accounts of the Company to the Buyer Parties and
            by executing such additional instruments and taking such additional
            acts as are reasonable and necessary. The Seller Parties shall use
            reasonable efforts to assist the Buyer Parties in obtaining or
            transferring Environmental Permits.

            (b) Following the Closing Date, the Sellers shall be entitled to
            receive all amounts collected in respect of the Assigned
            Receivables, and all amounts collected and received by the Company
            in respect of the Assigned Receivables shall be promptly remitted to
            the Sellers. Following the Closing Date, the Sellers shall be liable
            for and shall timely pay all amounts due under the Retained
            Liabilities, and any invoices or demands received by the Company in
            respect of the Retained Liabilities shall be promptly sent to the
            Sellers.

            (c) Immediately prior to the Closing, the Company shall distribute
            all cash on hand of the Company as of the Closing Date to the
            Sellers.

      5.14  SELLERS' INVESTMENT REPRESENTATIONS AND COVENANTS.

            (a) Each of the Sellers understands that neither the convertible
            notes of Parent to be issued pursuant to this Agreement ("Notes")
            nor the shares of Parent Common Stock to be issued to the Sellers
            pursuant to this Agreement, including the shares of Parent Common
            Stock to be issued upon conversion of the Notes (the "Shares") will
            be registered under the Securities Act of 1933, as amended (the
            "Securities Act") or any state securities laws and are being issued
            pursuant to an exemption from registration pursuant to Section 4(2)
            of the Securities Act or Regulation D promulgated under the
            Securities Act and pursuant to similar provisions of applicable
            state securities laws. Each of the Sellers understands that the
            reliance of Parent on such exemptions is predicated in part on the
            Seller's representations, warranties, covenants and acknowledgments
            set forth in this Section 5.14.

            (b) Each of the Sellers agrees that appropriate "stop-transfer"
            instructions will be given to Parent's transfer agent regarding the
            Shares and that the certificates representing the Shares shall be
            stamped or otherwise imprinted with a restrictive legend
            substantially similar to the following:

            THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933 (THE

                                      31



            "ACT") AND ARE "RESTRICTED SECURITIES" AS THAT TERM IS DEFINED IN
            RULE 144 OF THE ACT. THE SHARES MAY NOT BE OFFERED FOR SALE, SOLD OR
            OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED EXCEPT
            PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR
            PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER ACT, THE
            AVAILABILITY OF WHICH IS TO BE ESTABLISHED TO THE SATISFACTION OF
            THE ISSUER.

            (c) Except as disclosed on the Investment Representations Schedule
            attached hereto, each of the Sellers represents and warrants that
            such Seller is an "accredited investor" as defined in Rule 501
            promulgated under the Securities Act.

            (d) Each of the Sellers represents and warrants that the Notes and
            the Shares will be acquired by such Seller for such Seller's own
            account, not as a nominee or agent, and without a view to resale or
            other distribution within the meaning of the Securities Act and the
            rules and regulations thereunder and that such Seller will not
            distribute any of the Notes or the Shares in violation of the
            Securities Act. In the event that Joseph LoConti desires to transfer
            any of the Shares received by him pursuant to this Agreement to Don
            Morehead, such shares may only be transferred after complying with
            the following conditions: (i) Don Morehead shall execute and deliver
            an agreement whereby he makes the investment representations of the
            Sellers and agrees to abide and be bound by the covenants of the
            Sellers set forth in subsections (a) through (i) of this Section
            5.14 and shall provide such other information as reasonably
            requested by Parent; (ii) such transfer shall be made pursuant to a
            registration statement or an exemption from the registration
            requirements of the Securities Act and any applicable state
            securities laws, and (iii) Parent shall receive a legal opinion of
            counsel reasonably acceptable to Parent described in Section 5.14(i)
            hereof.

            (e) Each of the Sellers represents and warrants that the address set
            forth below such Seller's name in the Investment Representations
            Schedule is such Seller's principal residence.

            (f) Each of the Sellers (i) acknowledges that the Notes and the
            Shares issued, or to be issued, to such Seller must be held
            indefinitely by such Seller unless subsequently registered under the
            Securities Act or an exemption from registration is available, (ii)
            is aware that any routine sales of Shares made pursuant to Rule 144
            under the Securities Act may be made only in limited amounts and in
            accordance with the terms and conditions of that Rule and that in
            such cases where the Rule is not applicable, compliance with some
            other registration exemption will be required, and (iii) is aware
            that Rule 144 is not currently available for use by such Seller for
            resale of any of the Notes or the Shares to be acquired by such
            Seller pursuant to this Agreement.

                                      32



            (g) Each of the Sellers represents and warrants to Parent that such
            Seller has such knowledge and experience in financial and business
            matters such that such Seller is capable of evaluating the merits
            and risks of such Seller's investment in any of the Shares to be
            acquired by such Seller.

            (h) Each of the Sellers confirms that he or it has received and read
            (i) Parent's registration statement on Form S-1, as amended (ii)
            Parent's quarterly report on Form 10-Q for the quarter ended June
            30, 2004, and (iii) Parent's quarterly report on Form 10-Q for the
            quarter ended September 30, 2004. Each of the Sellers also confirms
            that Parent has made available to such Seller the opportunity to ask
            questions of and receive answers from it concerning the terms and
            conditions of such Seller's investment in the Shares, and the Seller
            has received to such Seller's satisfaction, such additional
            information, in addition to that set forth herein, about Parent's
            operations and the terms and conditions of this Agreement as such
            Seller has requested.

            (i) In order to ensure compliance with the provisions of this
            Section 5.14, each Seller agrees that after the Closing Date such
            Seller will not sell or otherwise transfer or dispose of the Notes
            or the Shares or any interest therein (unless such shares have been
            registered under the Securities Act) without first complying with
            either of the following conditions, the expenses and costs of
            satisfaction of which shall be fully borne and paid for by such
            Seller:

                  (A) Parent shall have received a written legal opinion from
                  legal counsel, which opinion and counsel shall be satisfactory
                  to Parent in the exercise of its reasonable judgment, or a
                  copy of a "no-action" or interpretive letter of the Securities
                  and Exchange Commission specifying the nature and
                  circumstances of the proposed transfer and indicating that the
                  proposed transfer will not be in violation of any of the
                  registration provisions of the Securities Act and the rules
                  and regulations promulgated thereunder; or

                  (B) Parent shall have received an opinion from its own
                  counsel, to the effect that the proposed transfer will not be
                  in violation of any of the registration provisions of the
                  Securities Act and the rules and regulations promulgated
                  thereunder, provided that if such Seller has complied with the
                  holding period and other requirements of Rule 144 under the
                  Securities Act in connection with such sale or transfer, such
                  opinion shall be furnished at Parent's expense.

            This paragraph shall no longer be applicable to any Notes or Shares
            following their transfer pursuant to a registration statement
            effective under the Securities Act or if the opinion of counsel
            referred to above is to the further effect that transfer
            restrictions and the legend referred to herein are no longer
            required in order to establish compliance with any provisions of the
            Securities Act.

            (j) The Parties agree that, upon a Seller's request, the restrictive
            legend set forth in Section 5.14(b) may be removed from such
            Seller's certificates evidencing

                                      33



            Shares in the following circumstances: (i) following any sale of
            such Shares pursuant to Rule 144 under the Securities Act; (ii) if
            such Shares are eligible for sale under Rule 144(k) under the
            Securities Act; or (iii) if Parent receives a written opinion of
            counsel reasonably satisfactory to Parent to the effect that such
            legend is not required under applicable requirements of the
            Securities Act (including judicial interpretations and
            pronouncements issued by the staff of the Securities and Exchange
            Commission); provided, however, that in connection with the issuance
            of the Shares, each Seller hereby agrees to adhere to and abide by
            all prospectus delivery requirements under the Securities Act and
            rules and regulations of the Securities and Exchange Commission.
            Parent agrees that, upon a Seller's written request to remove the
            restrictive legend from such Seller's certificate evidencing such
            Seller's Shares, which written request shall have been delivered to
            Parent at a time when such restrictive legend is eligible for
            removal under this Section 5.14(j), Parent will, reasonably promptly
            following the delivery by a Seller to Parent or Parent's transfer
            agent of the certificate representing the Shares issued with a
            restrictive legend, deliver or cause to be delivered to such Seller
            a certificate representing such Shares that is free from all
            restrictive legends. Each Seller agrees that the removal of the
            restrictive legend from certificates representing the Shares as set
            forth in this Section 5.14(j) is predicated upon Parent's reliance
            that no Seller will sell any Shares except pursuant to either the
            registration requirements of the Securities Act, including any
            applicable prospectus delivery requirements, or an exemption
            therefrom.

            (k) If the Company shall determine to prepare and file with the
            Securities and Exchange Commission a registration statement on Form
            S-3 or its successor form (each as promulgated under the Securities
            Act) relating to an offering of shares of the Company's Common Stock
            under the Securities Act in which any of its directors or executive
            officers are selling security holders other than with respect to any
            equity securities issuable in connection with stock option or other
            employee benefit plans of the Company, then the Company shall send
            to each Seller who holds Shares a written notice of such
            determination and, if within fifteen days after the date of such
            notice, any such Seller shall so request in writing, the Company
            shall include in such registration statement all or any part of the
            Shares held by such Seller that such Seller requests to be
            registered on and subject to the same terms and conditions as
            applicable to Parent's directors and officers who are selling
            security holders under such registration statement, including but
            not limited to any underwriting cutbacks, furnishing of information
            and liability and indemnification therefore and allocation of costs
            and expenses of registration; provided, that, the Company shall not
            be required to register any Shares pursuant to this Section 5.14(k)
            that are eligible for resale pursuant to Rule 144 or Rule 144(k)
            promulgated under the Securities Act or that are the subject of a
            then effective registration statement.

6.    NONCOMPETITION

      6.1   PROHIBITED ACTIVITIES:

                                      34



            (a) Except as set forth in the following paragraph, none of the
            Sellers (the "Restricted Parties"), shall for any reason whatsoever,
            directly or indirectly, for himself or on behalf of or in
            conjunction with any other person, company, partnership, corporation
            or business of whatever kind or nature, engage, as an officer,
            director, shareholder, owner, member, partner, joint venturer,
            lender or in any other capacity, whether as an employee, independent
            contractor, consultant, advisor, or otherwise, or as a sales
            representative, of any business in direct or indirect competition
            with the Company, Parent or any Affiliate of Parent located *** (the
            "Non-Compete Area").

            (b) Notwithstanding the foregoing provisions of this paragraph (a)
            each Restricted Party may (i) be a passive investor owning no more
            than five percent (5%) of the outstanding equity securities of any
            corporation or other entity the equity securities of which are
            listed on a national securities exchange or traded on the NASDAQ
            National Market System and with which such persons have no other
            connection whatsoever and/or (ii) invest in or act as an employee
            of, consultant for, or hold another position with, Parent;

            (c) The Restricted Parties shall not, and each of them shall cause
            each of his Affiliates not to, offer to employ any person (other
            than Ronald Boerema or Jason Stevens) who is, at that time, or who
            has been within one (1) year prior to that time, an employee of the
            Company;

            (d) With respect to operations or transactions in the Non-Compete
            Area, the Restricted Parties shall not, and each of them shall cause
            his Affiliates to not, engage or participate in any effort or act to
            solicit or induce any customer, supplier, associate, employee, sales
            or other agent, independent contractor, or other person in a
            business relationship with Parent or which has been a customer,
            supplier, associate, employee, sales or other agent, independent
            contractor, or other person in a business relationship with Parent
            within *** prior to that time, to discontinue such relationship with
            Parent or to take any action which might be disadvantageous to
            Parent or not to take any action which might be advantageous to
            Parent;

            (e) With respect to operations or transactions in the Non-Compete
            Area, none of the Restricted Parties shall, for any reason
            whatsoever, directly or indirectly for himself or on behalf of or in
            conjunction with any other person, company, partnership, corporation
            or business of whatever kind or nature, call upon any prospective
            acquisition candidate of such persons, on such persons' behalf or on
            behalf of any competitor, which candidate was either called upon by
            or for which Parent or its Affiliates made an acquisition analysis,
            for the purpose of acquiring such entity.

            (f) The time period for the restrictions set forth in this Article 6
            shall be *** after the Closing Date.

                                      35



      6.2   DAMAGES. The Restricted Parties each acknowledge that the damages
            that would be suffered by the Buyer Parties and the Company as a
            result of any breach of the provisions of this Article 6 may not be
            calculable and that an award of a monetary judgment for such a
            breach would be an inadequate remedy. Consequently, the Buyer
            Parties and the Company shall have the right, in addition to any
            other rights they may have, to obtain, in any court of competent
            jurisdiction, injunctive relief to restrain any breach or threatened
            breach of any provision of this Article 6 or otherwise to
            specifically enforce any of the provisions hereof, and none of the
            Buyer Parties or the Company shall be obligated to post a bond or
            other security in seeking such relief. This remedy is in addition to
            damages directly or indirectly suffered by the Buyer Parties and
            reasonable attorneys fees.

      6.3   INDEPENDENT COVENANT. All of the covenants contained in this Article
            6 shall be construed as an agreement independent of any other
            provision of this Agreement, and the existence of any claim or cause
            of action of the Restricted Parties against either of the Buyer
            Parties, whether predicated on this Agreement or otherwise, shall
            not constitute a defense to the enforcement by the Buyer Parties of
            such covenants.

      6.4   MATERIALITY AND ENFORCEABILITY. The Restricted Parties each agree
            that the covenants contained in this Article 6 are a material and
            substantial part of this transaction. The Parties agree that a
            portion of the consideration paid by the Buyer Parties pursuant to
            this Agreement is in exchange for the covenants contained in this
            Article 6, and therefore, the duration and area for which the
            covenants in this Article 6 are to be effective are reasonable. In
            the event that any court finally determines that the time period or
            the geographic scope of any such covenant is unreasonable or
            excessive and any covenant is to that extent made unenforceable, the
            Parties agree that the restrictions of this Article 6 shall remain
            in full force and effect for the greatest time period and within the
            greatest geographic area that would not render it unenforceable. The
            Parties intend that each of the covenants in Article 6 shall be
            deemed to be a separate covenant.

7.    SURVIVAL OF COVENANTS, REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

      7.1   SURVIVAL OF COVENANTS, REPRESENTATIONS, AND WARRANTIES. Except as
            set forth below in respect of certain representations and warranties
            of the Seller Parties (as defined in Article 3), the covenants,
            representations and warranties of the Parties contained in this
            Agreement shall survive the Closing hereunder and continue in full
            force and effect for the longer of (a) ***, or (b) the expiration of
            the statute of limitations applicable to such representation,
            warranty or covenant, and thereafter shall terminate ("Expiration
            Date"). Notwithstanding the foregoing, (x) the indemnification
            obligations for any misrepresentations contained in Sections 3.18
            and 3.20 shall survive the Closing and shall continue in full force
            until the later of (i) the date upon which the liability to which
            any such Tax claim may relate is barred by all applicable statutes
            of limitation, taking into account any extensions or waivers
            thereof; or (ii) the date upon which any claim for refund or credit

                                      36



            related to such Tax claim is barred by all applicable statutes of
            limitation, (y) the indemnification obligations for any
            misrepresentations contained in Sections 3.29 shall survive the
            Closing hereunder and continue in full force and effect for ***, and
            (z) the indemnification obligations for any misrepresentations
            contained in Sections 3.3 shall survive the Closing hereunder and
            continue in full force and effect forever thereafter, without
            limitation as to time.

      7.2   INDEMNIFICATION BY THE SELLERS. The Sellers jointly and severally,
            unconditionally, absolutely and irrevocably agree to and shall
            defend, indemnify and hold harmless the Buyer Parties and the
            Company, and each of their respective subsidiaries, shareholders,
            affiliates, officers, directors, employees, counsel, agents,
            successors, assigns heirs and legal and personal representatives
            (the Buyer Parties, the Company and all such persons or entities are
            collectively referred to as "Buyer's Indemnified Persons") from and
            against, and shall reimburse Buyer's Indemnified Persons for, each
            and every Loss paid, imposed on or incurred by Buyer's Indemnified
            Persons, directly or indirectly, relating to, resulting from or
            arising out of: (a) any inaccuracy in any representation or warranty
            of the Seller Parties under this Agreement, or the Schedules hereto,
            whether or not Buyer's Indemnified Persons relied thereon or had
            knowledge thereof, or any breach or nonfulfillment of any covenant,
            agreement or other obligation of the Seller Parties under this
            Agreement or any agreement or document delivered pursuant hereto;
            (b) all liabilities of the Company on or prior to the Closing Date,
            including, but not limited to claims, demands and causes of action
            against the Company and/or the Buyer Parties arising from or related
            to the ownership or operation of the assets of the Company and the
            Business on or prior to the Closing Date; (c) all Environmental
            Claims arising with respect to facts, conditions, events, operations
            and circumstances existing on or prior to the Closing Date; (d) the
            Retained Liabilities; and (e) any other facts or circumstances in
            any manner relating to the period ending on the Closing Date.

      7.3   INDEMNIFICATION BY THE BUYER PARTIES. After the Closing Date, the
            Buyer Parties unconditionally, absolutely and irrevocably agrees to
            and shall defend, indemnify and hold harmless the Sellers and their
            respective counsel, agents, contractors, successors, assigns, heirs
            and legal and personal representatives (the Sellers and such persons
            are collectively referred to as the "Sellers' Indemnified Persons")
            from and against, and shall reimburse the Sellers' Indemnified
            Persons for, each and every Loss paid, imposed on or incurred by the
            Sellers' Indemnified Persons, directly or indirectly, relating to,
            resulting from or arising out of (a) any inaccuracy in any
            representation or warranty of the Buyer Parties under this
            Agreement, whether or not the Sellers' Indemnified Persons relied
            thereon or had knowledge thereof, or any breach or nonfulfillment of
            any covenant, agreement or other obligation of the Buyer Parties
            under this Agreement or any agreement or document delivered pursuant
            hereto; (b) all liabilities of the Company arising after the Closing
            Date that are not attributable to the period of time on or prior to
            the Closing Date, including, but not limited to claims, demands and
            causes of action against the Company and/or the Buyer Parties
            arising from or related to the ownership or operation of the Company
            after the Closing Date; (c) all

                                      37



            Environmental Claims arising with respect to facts, conditions,
            events, operations and circumstances arising solely after the
            Closing Date; provided, however, that in the event of any
            Environmental Claim that arises with respect to facts, conditions,
            events, operations and circumstances arising both before and after
            the Closing Date, the Buyer Parties' indemnification obligations
            shall be limited to such matters arising with respect to facts,
            conditions, events, operations and circumstances after the Closing
            Date; and (d) any other facts or circumstances in any manner
            relating to the period after the Closing Date.

      7.4   NOTICE AND DEFENSE OF THIRD PARTY CLAIMS.

            If any Proceeding shall be brought or asserted under this Article 7
            against an indemnified party or any successor thereto (the
            "Indemnified Person") in respect of which indemnity may be sought
            under this Article 7 from an indemnifying person or any successor
            thereto (the "Indemnifying Person"), the Indemnified Person shall
            give prompt written notice of such Proceeding to the Indemnifying
            Person who shall assume the defense thereof, including the
            employment of counsel reasonably satisfactory to the Indemnified
            Person and the payment of all expenses; provided, that any delay or
            failure to so notify the Indemnifying Person shall relieve the
            Indemnifying Person of its obligations hereunder only to the extent,
            if at all, that it is prejudiced by reason of such delay or failure.
            In no event shall any Indemnified Person be required to make any
            expenditure or bring any cause of action to enforce the Indemnifying
            Person's obligations and liability under and pursuant to the
            indemnifications set forth in this Article 7. In addition, the
            filing of a Proceeding shall not be required as a condition or
            prerequisite to the Indemnifying Person's obligations under this
            Article 7, if the Indemnified Person is required to expend sums for
            investigation or remedial purposes as a result of a threatened
            Proceeding. The Indemnified Person shall have the right to employ
            separate counsel in any of the foregoing Proceedings and to
            participate in the defense thereof, but the fees and expenses of
            such counsel shall be at the expense of the Indemnified Person
            unless the Indemnified Person shall in good faith determine that
            there exist actual or potential conflicts of interest which make
            representation by the same counsel inappropriate. The Indemnified
            Person's right to participate in the defense or response to any
            Proceeding should not be deemed to limit or otherwise modify its
            obligations under this Article 7. In the event that the Indemnifying
            Person, within 15 days after notice of any such Proceeding, fails to
            assume the defense thereof, the Indemnified Person shall have the
            right to undertake the defense, compromise or settlement of such
            Proceeding for the account of the Indemnifying Person, subject to
            the right of the Indemnifying Person to assume the defense of such
            Proceeding with counsel reasonably satisfactory to the Indemnified
            Person at any time prior to the settlement, compromise or final
            determination thereof. Anything in this Article to the contrary
            notwithstanding, the Indemnifying Person shall not, without the
            Indemnified Person's prior written

                                      38



            consent, settle or compromise any Proceeding or consent to the entry
            of any judgment with respect to any Proceeding for anything other
            than money damages paid by the Indemnifying Person. The Indemnifying
            Person may, without the Indemnified Person's prior written consent,
            settle or compromise any such Proceeding or consent to entry of any
            judgment with respect to any such Proceeding that requires solely
            the payment of money damages by the Indemnifying Person and that
            includes as an unconditional term thereof the release by the
            claimant or the plaintiff of the Indemnified Person from all
            liability in respect of such Proceeding. The Indemnified Person
            shall not, without the Indemnifying Person's prior written consent,
            settle or compromise any Proceeding or consent to the entry of any
            judgment with respect to any Proceeding. Notwithstanding the
            foregoing, if the Indemnified Person reasonably believes that the
            pendency of such Proceeding would have a material adverse effect on
            the Indemnified Person, the Indemnified Person may, after delivering
            written notice of such proposed action to the Indemnifying Person,
            settle or compromise any such Proceeding or consent to entry of any
            judgment with respect to any such Proceeding without the
            Indemnifying Person's prior written consent; provided, however,
            that, if within seven (7) days after receipt by the Indemnifying
            Person of such written notice from the Indemnified Person, the
            Indemnifying Person delivers written notice to the Indemnified
            Person to the effect that the Indemnifying Person disputes its
            liability, or the amount thereof, in respect of such Proceeding, the
            Indemnifying Person shall be liable for indemnification with respect
            to such Proceeding to the extent of the lesser of: (i) the amount of
            the Loss in respect of such Proceeding and the settlement thereof or
            (ii) the amount of Loss for which the Indemnifying Person would have
            been liable under this Agreement in the event that the Indemnified
            Person had not settled such Proceeding without the Indemnifying
            Person's prior written consent.

            Notwithstanding anything to the contrary in this Article 7, the
            Sellers shall not have any obligation to provide indemnification
            under this Agreement until the aggregate amount of the Buyer
            Indemnified Persons' Loss shall exceed $***, provided that the
            Sellers' indemnity obligations shall be for every dollar of the
            Buyer Indemnified Persons' Loss up to $*** (the "Maximum
            Indemnification Amount").

      7.5   PAYMENT AND INTEREST. The Indemnifying Person shall make any payment
            required to be made under this Section 7.5 in immediately available
            funds and on demand. Any amounts or payments required to be paid by
            an Indemnifying Person under this Section 7.5 which are not paid
            within fifteen (15) business days of receipt by the Indemnifying
            Person of the Indemnified Person's demand therefor shall thereafter
            be deemed delinquent, and the Indemnifying Person shall pay to the
            Indemnified Person immediately upon demand, interest at the lesser
            of six percent (6%) per annum or the highest amount allowed by Texas
            law, from the date such payment becomes delinquent to the date of
            payment of such delinquent sums.

      7.6   NEGLIGENCE AND STRICT LIABILITY. WITHOUT LIMITING OR ENLARGING THE
            SCOPE OF THE INDEMNIFICATION OBLIGATIONS SET FORTH IN THIS
            AGREEMENT, THE PARTIES HERETO SHALL BE ENTITLED TO INDEMNIFICATION
            IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF WHETHER THE LOSS
            OR CLAIM GIVING

                                      39



            RISE TO SUCH INDEMNIFICATION OBLIGATION IS THE RESULT OF THE STRICT
            LIABILITY OF THE PARTY INDEMNIFIED. THE INDEMNIFIED PARTY SHALL BE
            ENTITLED TO INDEMNIFICATION WITH RESPECT TO LOSSES OR CLAIMS ARISING
            IN PART FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY; PROVIDED THAT
            THE INDEMNIFIED PARTY SHALL NOT BE ENTITLED TO INDEMNIFICATION FOR
            THAT PERCENTAGE OF A LOSS OR CLAIM ATTRIBUTABLE TO THE INDEMNIFIED
            PARTY'S NEGLIGENCE. THE PARTIES AGREE THAT THIS PARAGRAPH
            CONSTITUTES A CONSPICUOUS LEGEND.

8.    BUYER PARTIES' CONDITIONS TO CLOSING.

      Unless waived, in whole or in part, in writing by Parent, the obligations
of the Buyer Parties to effect the transactions contemplated hereby and in the
other agreements referred to herein shall be subject to the satisfaction at or
prior to the Closing Date of each of the following conditions:

      8.1   REPRESENTATIONS AND WARRANTIES. Each of the representations and
            warranties of the Seller Parties in this Agreement and the
            disclosures contained in the exhibits and schedules to this

            that no such assignment shall reduce or otherwise vitiate any of the
            obligations of the Buyer Parties hereunder. This Agreement shall

            APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN

            (b) IF ANY DISPUTE ARISES OUT OF OR IN CONNECTION WITH THIS
            AGREEMENT OR THE TERMINATION THEREOF, OR THE RELATIONSHIP CREATED BY
            OR DESCRIBED IN THIS AGREEMENT, THE PARTIES AGREE TO BRING SUIT UPON
            ALL SUCH MATTERS THEN IN DISPUTE ONLY IN THE UNITED STATES DISTRICT

            DIVERSITY JURISDICTION, IN THE DISTRICT COURTS IN AND FOR HARRIS

                                      49



      12.9  SEVERABILITY. If for any reason whatsoever, any one or more of the
            provisions hereof shall be held or deemed to be illegal,
            inoperative, unenforceable or invalid as applied to any particular
            case or in all cases, such circumstances shall not have the effect
            of rendering such provision illegal, inoperative, unenforceable or
            invalid in any other case or of rendering any of the other
            provisions hereof illegal, inoperative, unenforceable or invalid.
            Furthermore, in lieu of each such illegal, invalid, unenforceable or
            inoperative provision, there shall be added automatically, as part
            of this Agreement, a provision similar in terms of such illegal,
            invalid, unenforceable or inoperative provision as may be possible
            and as shall be legal, valid, enforceable and operative.

      12.10 DRAFTING. The parties acknowledge and confirm that they and/or their
            respective attorneys have participated jointly in the review and
            revision of this Agreement and that it has not been written solely
            by any one party or counsel for any one party. The parties therefore
            stipulate and agree that the rule of construction to the effect that
            any ambiguities are to be or may be resolved against the drafting
            party shall not be employed in the interpretation of this Agreement
            to favor any party against another.

      12.11 REFERENCES. The use of the words "hereof," "herein," "hereunder,"
            "herewith," "hereto," "hereby," and words of similar import shall
            refer to this entire Agreement, and not to any particular article,
            section, subsection, clause, or paragraph of this Agreement, unless
            the context clearly indicates otherwise.

      12.12 CALENDAR DAYS, WEEKS, MONTHS AND QUARTERS. Unless otherwise
            specified herein, any reference to "day," "week," "month" or
            "quarter" herein shall mean a calendar day, week, month or quarter.

      12.13 GENDER; PLURAL AND SINGULAR. Unless the context clearly indicates
            otherwise, the singular shall include the plural and vice versa.
            Whenever the masculine, feminine or neuter gender is used
            inappropriately in this Agreement, this Agreement shall be read as
            if the appropriate gender had been used.

      12.14 CUMULATIVE RIGHTS. All rights and remedies specified herein are
            cumulative and are in addition to, not in limitation of, any rights
            or remedies the parties may have by statute, at law, in equity, or
            otherwise, and all such rights and remedies may be exercised
            singularly or concurrently.

      12.15 NO IMPLIED COVENANTS. Each party, against the other, waives and
            relinquishes any right to assert, either as a claim or as a defense,
            that any other party is bound to perform or liable for the
            nonperformance of any implied covenant or implied duty or implied
            obligation.

      12.16 INDIRECT ACTION. Where any provision hereof refers to action to be
            taken by any person or party, or which such person or party is
            prohibited from taking, such provision shall be applicable whether
            the action in question is taken directly or indirectly by such
            person or party.

                                      50



      12.17 ATTORNEYS' FEES. The prevailing party in any dispute between the
            parties arising out of the interpretation, application or
            enforcement of any provision hereof shall be entitled to recover all
            of its reasonable attorneys' fees and costs whether suit be filed or
            not, including without limitation costs and attorneys' fees related
            to or arising out of any trial or appellate proceedings.

      12.18 TIME OF THE ESSENCE. With regard to all dates and time periods set
            forth or referred to in this Agreement, time is of the essence.

                                CONVERTIBLE NOTE

$___________________                                            January 11, 2005

      FOR VALUE RECEIVED, the undersigned ("THE COMPANY") hereby promises to pay
to the order of _____________ ("HOLDER"), at the offices of
_______________________________ the principal sum of ________________________
Dollars ($__________), together with interest, as hereinafter described.

      The principal of this Note is due and payable on January 11, 2010 (the
"Maturity Date"). Interest on this Note shall be due and payable quarterly on
the 15th day following the close of each calendar quarter, as it accrues and at
maturity.

      The principal from day to day unpaid shall, except as stated below, bear
interest at a rate per annum which shall from day to day be equal to the lesser
of (a) the Maximum Rate (hereinafter defined) and (b) eight percent (8%).

      Interest shall be calculated on the basis of actual days (including the
first day but excluding the last day) elapsed but computed as if each calendar
year consisted of 360 days (unless the result would exceed the Maximum Amount,
in which event such interest shall be calculated on the basis of a year of 365
or 366 days, as the case may be).

      As used herein, the terms "MAXIMUM AMOUNT" and "MAXIMUM RATE" mean,
respectively, the maximum amount and the maximum rate of interest which, under
applicable law, the holder hereof is permitted to contract for, charge, take,
reserve or receive on this Note. Regardless of any other provision in this Note,
the Holder shall never be entitled to contract for, charge, take, reserve,
receive, or apply, as interest on this Note any amount in excess of the Maximum
Amount, and if the Holder ever contracts for, charges, takes, reserves, receives
or applies as interest any such excess, it shall be deemed a partial prepayment
of principal and treated hereunder as such and any remaining excess shall be
refunded to the Company. In determining whether or not the interest paid or
payable, under any specific contingency, exceeds



the Maximum Amount, the Company and the Holder shall, to the maximum extent
permitted under applicable law, (a) treat all advances as but a single extension
of credit (and the Holder and the Company agree that such is the case and that
any provision herein for multiple advances is for convenience only), (b)
characterize any nonprincipal payment as an expense, fee or premium rather than
as interest, (c) exclude voluntary prepayments and the effects thereof and (d)
"spread" the total amount of interest throughout the entire contemplated term of
this Note; provided that if this Note is paid in full prior to the end of the
full contemplated term hereof, and if the interest received for the actual
period of existence hereof exceeds the Maximum Amount, the Holder shall refund
such excess, and, in such event, the Holder shall not, to the extent permitted
by applicable law, be subject to any penalties provided by any laws for
contracting for, charging, taking, reserving or receiving interest in excess of
the Maximum Amount.

      Article 1. Prepayment and Conversion.

      (a)   At any time after the first anniversary of the date hereof that the
price per share of the Company's common stock, $0.01 par value per share (the
"Common Stock"), as reported by the Nasdaq Stock Market (or if the Common Stock
is not then trading on the Nasdaq Stock Market, the price per share of the
Common Stock as reported on such other national securities exchange on which the
Common Stock is then listed for trading), equals or exceeds Fifteen Dollars
($15.00) (the "Trigger Price"), the Company may, by written notice to the
Holder, either:

            (i) declare that all unpaid principal of, and accrued interest on,
      this Note shall, effective on the date of the written notice, with no
      further action of the Company or Holder, be converted into the right to
      receive fully paid and nonassessable shares of the Common Stock, computed
      to the nearest whole share, at the Conversion Price (as defined Article
      1(c)) in effect as of the date of such written notice, or

            (ii) prepay this Note, or any portion thereof, at any time and
      without premium or penalty, provided, however, that no prepayment shall be
      effective until after the expiration of thirty (30) days after the Company
      has notified the Holder of its intent to prepay the Note, and Holder has
      not elected pursuant to Article 1(b) to convert this Note into shares of
      Common Stock.

      (b)   At any time after the date hereof, the Holder may, by written notice
to the Company, declare that all unpaid principal of, and accrued interest on,
this Note shall, effective on the date of the written notice, with no further
action of the Company or Holder, be converted into the right to receive fully
paid and nonassessable shares of the Common Stock, computed to the nearest whole
share, at the Conversion Price in effect as of the date of such written notice.

      (c)   This Note shall be convertible as provided in Article 1(a) or (b) at
the rate per share (the "Conversion Price"), equal to $10.37, subject to
adjustment as provided in Article 1(d). In the event of any such conversion, the
Holder shall surrender this Note to the Company at its then principal offices.
Upon such surrender of the Note, the Company shall as promptly as practicable
deliver to Holder certificates evidencing the shares of Common Stock into which
the Note has been converted. No fractional shares or scrip representing
fractional shares will be issued, and the Company shall pay to the Holder in
cash or by check that amount representing any such fractional amount. The
Company shall at all times during which the Note shall be

                                       2



outstanding, reserve and keep available out of its authorized but unissued
stock, for the purpose of effecting the conversion of the Note, such number of
its duly authorized shares of Common Stock as shall from time to time be
sufficient to effect the conversion of the Note. Upon effectiveness of the
conversion as set forth in Article 1(a) or (b), as appropriate, this Note shall
no longer be deemed to be outstanding and all rights with respect hereto shall
immediately cease and terminate at such time, except only the right of Holder to
receive shares of Common Stock (and cash, if any, with respect to fractional
shares or any consideration payable pursuant to Article 1(d)) in exchange
therefor.

      (d)   The Trigger Price, the Conversion Price and the terms of this
Article 1 shall be subject to adjustment as follows. In case of a merger,
consolidation or other combination of the Company into any other corporation or
entity, or of the sale of the properties and assets of the Company as, or
substantially as, an entirety to any other corporation or entity, or if there is
a reclassification of the Common Stock, this Note shall after such merger,
consolidation, combination, sale or reclassification be convertible into the
right to receive the number of shares of stock or other securities or property
of the Company, or of the corporation or entity resulting from such
consolidation or combination or surviving such merger or to which such sale
shall be made, as the case may be, to which a holder of the Common Stock
issuable upon exercise of this Note would have been entitled upon such merger,
consolidation, combination, sale or reclassification, had this Note been
converted prior thereto (in each case, without accelerating the delivery
schedule set forth in Article 1(a) or (b)); and in any case, if necessary, the
provisions set forth in this Article 1 regarding the rights and interest of
Holder and the Company shall be appropriately adjusted so as to apply
thereafter, as nearly as possible, to the right to receive any shares of stock
or other securities or property thereafter deliverable on the conversion of this
Note. In the event of a dividend on the shares of Common Stock payable in shares
of Common Stock or in the event the outstanding shares of Common Stock shall be
subdivided (by stock split, or otherwise) into a greater number of shares of
Common Stock, the Trigger Price and the Conversion Price then in effect shall,
concurrently with the effectiveness of such stock dividend or subdivision, be
proportionately decreased. In the event the outstanding shares of Common Stock
shall be combined or consolidated, by reclassification or otherwise, into a
lesser number of shares of Common Stock, the Trigger Price and the Conversion
Price then in effect shall, concurrently with the effectiveness of such
combination or consolidation, be proportionately increased. In case the Company
shall make a special or extraordinary dividend or distribution to all holders of
Common Stock or evidences of indebtedness or assets (including cash and
securities, but excluding shares of Common Stock)(any of the foregoing, a
"Distribution") then either (i) the Company shall, if it so elects, reserve such
Distribution for distribution to Holder upon conversion of this Note so that
Holder will receive upon such conversion, in addition to the shares of Common
Stock to which Holder is entitled, the amount and kind of such Distribution
which Holder would have received if Holder had converted this Note into Common
Stock immediately prior to the record date for the Distribution, or (ii) the
Trigger Price and the Conversion Price shall be equitably adjusted to account
for such Distribution. All calculations under this Article 1(d) shall be made to
the nearest cent or the nearest share, as the case may be.

      (e)   The Company believes that the holding period, as determined by Rule
144(d)(3)(ii) promulgated by the Securities and Exchange Commission under the
Securities Act of 1933, as in effect on date hereof (the "Holding Period"), for
any shares of Common Stock

                                       3



acquired as a result of the conversion of this Note should commence on the date
hereof. To the extent that such conversion occurs more than two (2) years after
the date hereof and Rule 144(k) is otherwise applicable, the certificates
evidencing the shares of Common Stock into which the Note has been converted
shall be issued free of any legend or restriction on transfer. To the extent
that such conversion occurs more than one (1) year but less than two (2) years
after the date hereof, and Rule 144 is otherwise applicable, the certificates
evidencing the shares of Common Stock into which the Note has been converted
shall be issued with a legend in substantially the form set forth in Article 2,
and the Company shall assist in obtaining a legal opinion sufficient to allow
such shares to be transferred in accordance with an applicable exemption from
registration.

      Article 2. Transfer of the Note. This Note shall not be transferable
except by operation of law. This Note and each Note issued in exchange for or
upon transfer of this Note shall be stamped or otherwise imprinted with a legend
in substantially the following form:

THIS NOTE IS SUBJECT TO RESTRICTIONS ON TRANSFER CONTAINED IN ARTICLE 2 BELOW.
THIS NOTE AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
OR UNDER ANY APPLICABLE STATE SECURITIES LAWS, AND THEY CANNOT BE OFFERED FOR
SALE, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE HYPOTHECATED EXCEPT IN ACCORDANCE
WITH THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH STATE LAWS OR
UPON DELIVERY TO THE COMPANY OF AN OPINION OF LEGAL COUNSEL SATISFACTORY TO THE
COMPANY THAT AN EXEMPTION FROM REGISTRATION IS AVAILABLE.

      Article 3. Default.

          (a)   "Event of Default," wherever used herein, means any one of the
following events:

                (1)   default in the payment of any interest when due on this
          Note prior to the Maturity Date that is not cured by the Company
          within ten days after receiving written notice from the Holder of such
          default; or

                (2)   the entry of a decree or order for relief by a court
          having jurisdiction in respect of the Company in an involuntary case
          under the federal bankruptcy laws, as now or hereafter constituted, or
          any other applicable federal or state bankruptcy, insolvency or other
          similar law, or the appointment of a receiver, liquidator, assignee,
          custodian, trustee, sequestrator (or similar official) of the Company
          or for any substantial part of its property, or ordering the winding
          up or liquidation of its affairs and the continuance of any such
          decree or order unstayed and in effect for a period of sixty (60)
          consecutive days; or

                (3)   the commencement by the Company of a voluntary case under
          the federal bankruptcy laws, as now constituted or hereafter amended,
          or any other applicable federal or state bankruptcy, insolvency or
          other similar law, or the

                                       4



          consent by it to the appointment of or taking possession by a
          receiver, liquidator, assignee, trustee, custodian, sequestrator (or
          other similar official) of the Company or for any substantial part of
          its property, or the making by it of any assignment for the benefit of
          creditors, or the admission by it in writing of its inability to pay
          its debts generally as they become due.

                (b)   If an Event of Default occurs, then and in every such case
          Holder may (i) declare the principal and all accrued interest of this
          Note to be due and payable immediately, by a notice in writing to the
          Company, and upon any such declaration such principal shall become
          immediately due and payable, or (ii) convert this Note into shares of
          the Common Stock as more fully set forth in paragraph 1(b) hereof.

                (c)   If an Event of Default occurs and is continuing, Holder
          may pursue any available remedy to collect the payment of principal or
          interest on this Note or to enforce the performance of any provision
          hereof. A delay or omission by Holder in exercising any right or
          remedy accruing upon an Event of Default shall not impair the right or
          remedy or constitute a waiver of or acquiescence in the Event of
          Default. All remedies are cumulative to the extent permitted by law.

                (d)   The Company expressly waives all notices of nonpayment,
          demands for payment, presentations for payment, notices of intention
          to accelerate maturity, protest and notice of protest, and notices of
          acceleration of the indebtedness due hereunder.

      Article 4. Collection and Enforcement Fees. If an Event of Default occurs,
and this Note is placed in the hands of an attorney for collection or
enforcement (whether or not suit is filed), or if this Note is collected or
enforced by suit or legal proceedings or through bankruptcy proceedings, the
Company agrees to pay in addition to all sums then due hereon, including
principal and interest, all reasonable expenses of collection and enforcement
including reasonable attorneys' fees.

      Article 5. Amendments and Waivers. This Note may be amended by written
agreement of the Company and Holder. No waiver of the provisions hereof shall be
effective unless agreed to in writing by the party against whom such waiver is
asserted.

      Article 6. Severability Clause. In case any provision in this Note (other
than the obligation of the Company to pay principal and interest as and when
provided herein) shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

      Article 7. Notice. All notices to the Company required or permitted by
this Note shall be sufficient if given in writing and executed by Holder and if
notice is required or permitted from more than one Holder, such notice may be
executed in multiple counterparts. All such notices to the Company shall be
delivered by registered or certified mail, return receipt requested, or
personally delivered, to the Company at One Riverway, Suite 1400, Houston, Texas
77056, or such other address as the Company may designate by written notice to
Holder. Any notices by the Company to Holder shall be delivered by registered or
certified mail, return receipt requested, nationally recognized overnight
courier or personally delivered to Holder, at

                                       5



_____________________________________, or such other address as the Holder may
designate by written notice to the Company. Notices sent by mail as permitted
above shall be deemed given on the third business day after deposit, postage
paid, in the mails. All other notices shall be deemed given upon receipt.

      Article 8. Governing Law. This Note shall be deemed to be a contract made
under the laws of the State of Delaware and for all purposes shall be governed
by and construed in accordance with the laws of the State of Delaware, exclusive
of any such law under which the law of any other jurisdiction would apply.

      Article 9. Construction. The headings and captions used in this Note are
inserted solely for convenience in locating the provisions of this Note and not
as an aid in construction. The plural usage of a word shall be deemed to include
the singular thereof and vice versa. Each gender shall be deemed to include the
other genders.

duly authorized officer effective on the 11th day of January, 2005.

                                     RELEASE

      THIS RELEASE is being executed and delivered in accordance with the terms
of the Membership Interest Purchase Agreement of even date herewith (the
"Agreement") among WCA WASTE CORPORATION, a Delaware corporation ("Parent"),
Waste Corporation of Missouri, Inc., a Delaware corporation ("Buyer"), GECKO
INVESTMENTS, LLC, an Ohio limited liability company (the "Company"), ANDREW
ZELENKOFSKE, DANIEL J. CLARK, and JOSEPH LOCONTI (Zelenkofske, Clark and
LoConti, collectively, the "Sellers"). Capitalized terms used in this Release
without definition have the respective meanings ascribed to them in the
Agreement.

      WHEREAS, each of the Sellers acknowledges that the execution and delivery
of this Release is a condition precedent to Parent's and Buyer's obligation to
purchase the outstanding membership interests of the Company pursuant to the
Agreement and that Parent and Buyer are relying on this Release in consummating
such purchase.

      NOW, THEREFORE, each of the Sellers, for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, and intending to
be legally bound, in order to induce Parent and Buyer to purchase the
outstanding membership interests of the Company pursuant to the Agreement,
hereby agrees as follows:

      Each of the Sellers hereby releases and forever discharges Parent, Buyer,
the Company, and each of their individual, joint or mutual, past, present and
future representatives, Affiliates, members, partners, controlling persons,
successors and assigns (individually, a "Releasee" and collectively,
"Releasees") from any and all claims, demands, proceedings, causes of action,
orders, obligations, contracts, agreements, debts and liabilities whatsoever,
whether known or unknown, suspected or unsuspected, contingent or fixed, both at
law and in equity, which the Sellers now have, have ever had or may hereafter
have against the respective Releasees arising contemporaneously with or prior to
the Closing or on account of or arising out of any matter, cause or event
occurring contemporaneously with or prior to the Closing, including, but not
limited to, any rights to indemnification or reimbursement from the Company,
whether pursuant to the organizational documents of the Company or otherwise and
whether or not relating to claims pending on, or asserted after, the Closing;
provided, however, that nothing contained herein shall operate to release any
obligations of Parent, Buyer or the Company arising under the Agreement or the
documents executed in connection therewith.

      Each of the Sellers hereby irrevocably covenants and agrees to refrain
from, directly or indirectly, asserting any claim or demand, or commencing,
instituting or causing to be commenced, any Proceeding of any kind against any
Releasee, based upon any matter purported to be released hereby.

      Without in any way limiting any of the rights and remedies otherwise
available to any Releasee against Sellers, each of the Sellers for himself,
shall indemnify and hold harmless each Releasee from and against all loss,
liability, claim, damage (including incidental and consequential damages) or
expense (including costs of investigation and defense and reasonable attorney's
fees), whether or not involving third party claims, arising directly or
indirectly from or in connection with the assertion of any claim or other matter
purported to be released pursuant to



this Release or the assertion by any third party of any claim or demand against
any Releasee which claim or demand arises directly or indirectly from, or in
connection with, any assertion by or on behalf of any Seller against such third
party of any claims or other matters purported to be released pursuant to this
Release.

      If any provision of this Release is held invalid or unenforceable by any
court of competent jurisdiction, the other provisions of this Release will
remain in full force and effect. Any provision of this Release held invalid or
unenforceable only in part or degree will remain in full force and effect to the
extent not held invalid or unenforceable. Furthermore, in lieu of each such
provision held to be invalid or unenforceable, there shall be added
automatically, as part of this Release, a provision as similar in terms of such
invalid or unenforceable provision as may be possible and as shall be valid and
enforceable.

      This Release may not be changed except in a writing signed by the
person(s) against whose interest such change shall operate. This Release shall
be governed by and construed under the laws of the State of Texas without regard
to its principles of conflicts of law.

      All words used in this Release will be construed to be of such gender or
number as the circumstances require.

                            [SIGNATURE PAGE FOLLOWS]
