<PAGE>

                  (1) 10,309 shares shall be retained and held back by the Buyer
                  Parties to reimburse and compensate the Buyer Parties and the
                  Company for any Losses related to the proposed Settlement
                  Agreement between the Company and the State of Missouri
                  (including any increase in the Company's or the Buyer Parties'
                  operating expenses resulting from covenants or conditions
                  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
                  Company for any Losses related to the failure to obtain, or
                  any delay in obtaining, all necessary approvals, permits,
                  consents and licenses of governmental authorities for the
                  opening and operation of a landfill cell under construction at
                  the Company's landfill located in Pike County, Missouri,
                  including costs, including lost profits, associated with
                  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

<PAGE>

            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

      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
            securities. Further, none of such membership interests were issued

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

            authorized but unissued membership interests. In addition, there are
            no (a) outstanding securities or obligations which are convertible
            into or exchangeable for any membership interests or other

            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.

            maintained in all respects in material compliance with the
            applicable requirements of ERISA, the Code and other applicable law

            material liabilities to the Company.

            (d) There are no voluntary employee benefit associations maintained

            sponsored by the Company. The consummation of any transaction
            contemplated by this Agreement will not result in any: (i) payment

            Company to any of its officers, employees, former employees or
            directors or to the trustee under any "rabbi trust" or similar

            (f) The Company does not provide any material post-retirement
            medical, health, disability or death protection coverage or

            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.

            Parties' investigation and representation by counsel shall not limit

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

      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

<PAGE>

            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

<PAGE>

            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

<PAGE>

            "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

<PAGE>

            (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

<PAGE>

            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

<PAGE>

            (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

<PAGE>

      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

<PAGE>

            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

<PAGE>

            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

<PAGE>

            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

<PAGE>

            RISE TO SUCH INDEMNIFICATION OBLIGATION IS THE RESULT OF THE STRICT
            LIABILITY OF THE PARTY INDEMNIFIED. THE INDEMNIFIED PARTY SHALL BE

      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.

            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.

                                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

<PAGE>

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

<PAGE>

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

<PAGE>

          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.

                              WCA WASTE CORPORATION

                              PERFORMANCE UNIT PLAN

I. BACKGROUND AND OBJECTIVES

The overall executive compensation strategy of WCA Waste Corporation ("WCA" or
"the Company") is to provide key executives with total direct pay opportunity
that generally is competitive with similar waste management companies. The
Performance Unit Plan ("PUP" or the "Plan") is a long-term incentive plan that
rewards three-year average annual WCA financial performance, as described in
this document.

The PUP rewards achievement of critical three-year average earnings per share
("EPS") growth and pre-tax, pre-interest return on invested capital ("ROIC")
goals of WCA. The following provisions hereof define PUP eligibility, the size
of potential award opportunities, performance measurement, form and timing of
award payments, administrative guidelines and definitions for ongoing PUP
management.

II. ELIGIBILITY

PUP award eligibility will be approved by the Compensation Committee of the WCA
Board of Directors (the "Compensation Committee") at the beginning of each
performance/award period. Generally, PUP participants will be selected from key
executives who primarily are responsible for the annual growth and profitability
of WCA, i.e., generally senior vice presidents and above. The number of eligible
PUP participants is expected to vary from year to year, as WCA expands and as
the Company's compensation strategy and programs are refined.

III. AWARD OPPORTUNITIES

At the beginning of each fiscal year, each participant in the PUP will be
assigned a targeted award opportunity of 100% of salary, that can decrease to
zero, based on performance achievement, measured over (overlapping) three-year
performance periods. The size of future PUP award opportunities and PUP
performance goals may be re-defined from time to time, as modifications are made
in WCA's executive compensation strategy.

                                       1
<PAGE>

Within 2 1/2 months after the end of each three-year performance cycle, each
participant's salary rate at the beginning of the PUP award cycle (just ended)
will be multiplied by the actual PUP award percentage earned to determine the
dollar value of the award for the prior performance cycle.

IV. PERFORMANCE MEASURES

The PUP will provide long-term incentive pay at risk, with potential PUP awards
in 2005 tied to the achievement of WCA average annual EPS growth and ROIC,
measured over three years from the date of the award. PUP awards made in 2005
will be weighted equally (50/50) for EPS growth and ROIC performance
achievement.

The PUP performance targets for each performance cycle will be set jointly by
the Compensation Committee and the senior officers of WCA at the beginning of
each fiscal year. Performance goals for PUP awards may be equal to or exceed the
goals in the WCA business plan. Such goals may be adjusted by the Compensation
Committee during a performance cycle, if a major change occurs in the Company's
capital structure, e.g., a major acquisition.

In addition to the PUP targets, the Compensation Committee and the senior
officers of WCA jointly will establish a minimum acceptable performance goals,
i.e., the performance levels below which no incentive will be paid. PUP awards
will be interpolated for actual performance falling between the minimum
acceptable and targeted goals. Prior to fiscal year end, the WCA senior officers
and Compensation Committee jointly will establish appropriate PUP goals for the
next three years, in support of the WCA business plan.

Exhibit 1 presents the performance matrix for calculating PUP awards for the
2005-2007 performance cycle. This performance matrix may be revised in the
future, as the Company's business strategy and performance focus of WCA changes.

V. AWARD VESTING

In the event of termination of the participant's employment during a PUP
performance cycle as a result of the participant's death, disability (defined
below), retirement (defined below) or a Change in Control (defined below), a
pro-rata share of each (overlapping) award earned shall be paid to the
participant (or his/her spouse or estate, as applicable, pursuant to Section
VI) at the

                                        2
<PAGE>

end of each PUP performance cycle, based on the date of termination. If a
participant's employment terminates during any PUP performance cycle for any
reason other than in connection with the events described in the immediately
preceding sentence, the participant shall be deemed not to have earned the award
or part thereof for any affected PUP performance cycle.

For purposes of the Plan, "Change in Control" shall mean the occurrence during
the term of this Plan, of any one of the following events:

      (i)   An acquisition of any common stock ("Common Stock"), par value $.01
            per share, of the Company or other securities entitled to vote, or
            convertible into or exercisable for securities entitled to vote, in
            the election of directors (such Common Stock and other securities
            hereinafter being referred to as the "Voting Securities") of the
            Company by any Person (as specified in Section 3(a)(9) of the
            Securities Exchange Act of 1934, as amended (the "Exchange Act"),
            and used in Sections 13(d) and 14(d) thereof), including for
            purposes of this Section the Company or its Affiliates, immediately
            after which such Person has Beneficial Ownership (as defined below)
            of fifty percent (50%) or more of the combined voting power of the
            Company's then outstanding Voting Securities; provided, however, a
            Change in Control shall not be deemed to have occurred by reason of
            an acquisition of fifty percent (50%) or more of the Company's
            Voting Securities by an employee benefit plan maintained by the
            Company or any of its Affiliates or by a Person in a Non-Control
            Transaction (as defined below); or

      (ii)  The individuals who, as of the date of this Agreement are members of
            the Board of Directors of the Company (the "Incumbent Board"), cease
            for any reason to constitute at least two/thirds (2/3) of the
            members of the Board of Directors of the Company; provided, however,
            that an individual will be treated as a member of the Incumbent
            Board if the members of the Board of Directors of the Company prior
            to such individual's nomination unanimously approve such
            individual's nomination and election to the Board of Directors of
            the Company and provided further that no individual shall be
            considered a member of the Incumbent Board if such individual
            initially assumed office as a result of either an actual or
            threatened

                                        3
<PAGE>

           proxy contest or other actual or threatened solicitation of proxies
           or consents by or on behalf of a Person other than the Board of
           Directors of the Company (a "Proxy Contest"), including by reason of
           any agreement intended to avoid or settle any Proxy Contest; or

     (iii) The consummation of:

            (A)   A merger, consolidation or reorganization with or into the
                  Company or in which securities of the Company are issued (a
                  "Merger"), unless such Merger, consolidation or reorganization
                  occurs in connection with a Non-Control Transaction;

            (B)   A complete liquidation or dissolution of the Company; or

            (C)   The sale or other disposition of all or substantially all of
                  the assets of the Company to any Person (other than a transfer
                  to an employee benefit plan or Affiliate of the Company or
                  under conditions that would constitute a Non-Control
                  Transaction with the disposition of assets being regarded as a
                  Merger for this purpose).

      As used herein the following terms have the following meanings:

      (i)   "Affiliate" shall have the meaning set forth in Rule 12b-2
            promulgated under Section 12 of the Exchange Act.

      (ii)  "Beneficial Ownership," "Beneficially Owned" and the like means
            having, with respect to a security or group of securities, the power
            to control or direct the voting or disposition of Voting Securities,
            as determined by Rule 13d-3 under the Exchange Act.

      (iii) "Non-Control Transaction" means a Merger whereby:

            (A)   the individuals who were the president, chief executive
                  officer and the chief financial officer of the Company hold
                  such respective positions with, and individuals who were
                  members of the Incumbent Board immediately

                  Merger, constitute at least a majority of the members of the
                  board of directors of, the surviving corporation; and

            (B)   either (1) fifty percent (50%) or more of the combined voting
                  power of the then outstanding voting securities of the
                  surviving corporation is Beneficially Owned directly by the
                  Beneficial Owners of the Company's Voting Securities prior to

                  and/or chief financial officer of the Company, as a result of
                  such Merger, acquire (or their Affiliates acquire) fifty

To the extent that Section 409A of the Internal Revenue Code of 1986, as
amended, applies to any PUP award, this definition is intended to comply with
the definition of change in control under Section 409A of the Internal Revenue
Code of 1986, as amended (the "Code"), as in effect from time to time and, to
the extent that the above definition does not so comply, such definition shall
be void and of no effect and, to the extent required to ensure that this
definition complies with the requirements of Section 409A of the Code, the
definition of such term set forth in regulations or other regulatory guidance
issued under Section 409A of the Code by the appropriate governmental authority
is hereby incorporated by reference into and shall form part of this Agreement

accordance with the definition prescribed in such regulations or other
regulatory guidance.

In addition, "disability" shall mean that the participant has been receiving
full or partial salary payments under the Company's disability plans for a
period of 18 consecutive months by reason of any medically determinable physical
or mental impairment which can be expected to result in death or can be expected
to last for a continuous period of not less than 12 consecutive months.

Moreover, "retirement" shall mean termination of a participant's employment with
the Company under circumstances as shall constitute retirement under Company

VI. FORM AND TIMING OF ANNUAL AWARD COMPONENTS

PUP awards will be paid in a lump sum in cash within 2 1/2 months after the end
of each three-year performance cycle; provided, however, the Company shall
deduct from all PUP awards payable under this Plan any taxes required to be
withheld by the Federal or any state or local government. No participant shall
be permitted to elect to defer all or any portion of his/her award relating to
any relevant measurement period hereunder.

All awards payable under this Plan shall be the obligation of the Company. If
the Company determines that any person entitled to payments under this Plan is
physically or mentally incompetent to receive or properly receipt for such
payments, the Company shall make such payments to the legal guardian or other
personal representative of such person for the use and benefit of such person.
If the Company for any reason is unable to determine with reasonable certainty
the proper person to pay pursuant to the terms of the immediately preceding
sentence, the Company shall pay any amounts due hereunder into a court of
competent jurisdiction in an interpleader proceeding for purposes of being
directed by such court as to the proper disposition of any such amounts due
hereunder. Any such payments so made by the Company to the extent of the amounts
thereof, shall fully discharge the Company's obligations hereunder.

Should the participant die prior to receiving all amounts due under this Plan,
any unpaid amounts due hereunder shall be made to the participant's spouse, if
such spouse survives the participant, or, if there is no surviving spouse, to
the legal representative of the participant's estate, or if no administration is
had on the estate, to the person or persons to whom participant's property shall
pass by applicable laws of descent and distribution.

VII. ADMINISTRATIVE GUIDELINES AND DEFINITIONS

The PUP shall be administered by the Compensation Committee. The Compensation
Committee shall have such authority and powers, may consult with WCA's CEO or
such other person or persons, as it shall deem necessary or advisable to
facilitate the intent and purpose of the PUP. All decisions made by the
Compensation Committee shall be final and binding.

      -     Employee Termination - A participant must be an employee of the
            Company on the final day of the measurement period.

                                        6

      -     New Hires - Newly hired participants shall earn PUP awards on a
            pro-rata basis, based on their date of employment.

      -     Base Salary Rate - Base salary for PUP award calculations shall be
            the annualized base rate in effect at the beginning of the
            performance cycle for which the award is paid.

      -     Support Documentation - The WCA CFO shall be responsible for
            maintaining all necessary support documentation regarding
            performance and bonus calculations under the PUP.

VIII. MISCELLANEOUS

      (a)   RIGHTS OF PARTICIPANTS. Nothing in this Plan shall be construed to:

            (i)   Give the participant any rights whatsoever with respect to any
                  PUP award until such award becomes vested, nonforfeitable and
                  distributable in accordance with the terms of this Plan;

            (ii)  Limit in any way the right of the Company to terminate the
                  participant's employment by the Company at any time;

            (iii) Give the participant or any other person any interest in any
                  fund or in any specific asset or assets of the Company;

            (iv)  Give the participant or any other person any interest or right
                  other than those of any unsecured general creditor of the
                  Company; or

            (v)   Be evidence of any agreement or understanding, express or
                  implied, that the Company will employ the participant in any
                  particular position or at any particular rate of remuneration.

      (b)   NONALIENATION OF BENEFITS. No right or benefit under this Plan shall
            be subject to anticipation, alienation, sale, assignment, pledge,
            encumbrance, or charge, and any attempt to anticipate, alienate,
            sell, assign, pledge, encumber, or charge the same will be void. No
            right to interest hereunder shall in any manner be liable for

                                        7
<PAGE>

            or subject to any debts, contracts, liabilities, or torts of the
            person entitled to such right or interest.

      (c)   PREREQUISITES TO BENEFITS. Neither the participant, nor any person
            claiming through the participant, shall have any right or interest
            in this Plan, or any PUP award hereunder, unless and until all the
            terms, conditions, and provisions of this Plan which affect the
            participant or such other person shall have been complied with as
            specified herein.

      (d)   SECTION 162m COMPLIANCE. Should any participant in the Plan be or
            become a "covered employee" as such term is defined in section
            1.162-27(c)(2) of the Treasury Regulations, then notwithstanding
            anything herein to the contrary, with respect to any action taken
            under the Plan by the Compensation Committee in respect of any such
            covered employee, the Compensation Committee shall be comprised
            solely of two or more "outside directors" of the Company as such
            term is defined in section 1.162-27(e)(3) of the Treasury
            Regulations, the material terms of the Plan shall be disclosed to
            and approved by the stockholders of the Company prior to the payment
            of any PUP awards and the Plan shall, in all other respects, meet
            the requirements of section 162(m) of the Code and the regulations
            promulgated pursuant thereto, prior to any payments hereunder. In
            furtherance of the above provisions of this Section VIII(d), the
            Compensation Committee shall bifurcate the Plan so as to restrict,
            limit or condition the use or application of any provision of the
            Plan to participants who are covered employees without so
            restricting, limiting or conditioning the Plan with respect to other
            participants, unless the Compensation Committee, in its sole
            discretion, determines to apply such restrictions, limitations or
            conditions to participants who are not covered employees.

      (e)   BONUS ARRANGEMENT. This Plan is intended to be a bonus program that
            is designed to provide an on-going, pecuniary incentive for the
            participant to produce the participant's best efforts to increase
            the value of the Company. This Plan is not intended to provide
            retirement income or to defer the receipt of

                                        8
<PAGE>

            payments hereunder to the termination of the participant's covered
            employment or beyond. This Plan is strictly an incentive bonus
            program (as described in U.S. Department of Labor Regulation Section
            2510.3-2(c) or any successor thereto), and not a pension or welfare
            benefit plan that is subject to the Employee Retirement Income
            Security Act of 1974, as amended ("ERISA"). All interpretations and
            determinations hereunder shall be made on a basis consistent with
            the status of the Plan as a bonus program.

      (f)   AMENDMENT. This Plan may be modified or terminated by the Company at
            any time; provided, however, that no such modification or
            termination shall affect any right to any PUP awards that are vested
            at the time of such modification or termination except with the
            written consent of the affected participant.

      (g)   POWERS OF THE COMPANY. The existence of outstanding and unpaid
            contingent interests under the Plan shall not affect in any way the
            right or power of the Company to make or authorize any adjustments,
            recapitalization, reorganization or other changes in the Company's
            capital structure or in its business, or any merger or consolidation
            of the Company, or any issue of bonds, debentures, common or
            preferred stock, if applicable, or the dissolution or liquidation of
            the Company, or any sale or transfer of all or any part of its
            assets or business, or any other act or proceeding, whether of a
            similar character or otherwise.

      (h)   WAIVER. A waiver by the Company, or the participant, of any of the
            terms or conditions contained in the Plan shall not be construed as
            a general waiver by such party of any other terms or conditions
            contained in this Plan.

      (i)   SEPARABILITY. If any provision or provisions of this Plan shall be
            found to be invalid, illegal, or unenforceable in any respect, such
            invalid, illegal, or unenforceable provision shall be severed from
            this Plan and shall not affect the validity, legality and
            enforceability of the remainder of this Plan.

      (j)   GENDER, TENSE AND HEADINGS. Whenever the context requires, words of
            the masculine gender used herein shall include the feminine and
            neuter, and words

                                        9
<PAGE>

            used in singular shall include plural. Headings of Articles and
            Sections, as used herein, are inserted solely for convenience and
            reference and constitute no part of this Plan.

      (k)   GOVERNING LAW. This Plan shall be subject to and governed by the
            laws of the State of Texas and, to the extent applicable, the laws
            of the United States.

      (l)   NOTICE. Any notice required or permitted to be given under this Plan
            shall be sufficient if in writing and hand delivered, or sent by
            registered or certified mail, to the Compensation Committee, the
            Company, participant or beneficiary, as applicable, at the address
            last furnished by such person. Such notice shall be deemed given as
            of the date of delivery or, if delivery is made by mail, as of the
            dates shown on the postmark on the receipts for registration or
            certification.

      (m)   EFFECTIVE DATE. This Plan is effective as of January 1, 2005 and any
            amendment of this Plan shall be effective as of the date provided
            therein.
