                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT, dated as of March 31, 2000 (together
with the Earnout Agreement between Compost and Purchaser in the form attached
hereto as Exhibit H, the "Agreement"), is by and between SYNAGRO TECHNOLOGIES,
INC., a Delaware corporation (the "Purchaser"), and COMPOST AMERICA HOLDING
COMPANY, INC., a New Jersey corporation ("Compost"). The Purchaser and Compost
are each referred to as a "Party" and, collectively, they are sometimes referred
to as the "Parties." Environmental Protection & Improvement Company, Inc., a New
Jersey corporation (the "Company"), has joined this Agreement solely for
purposes of making the representations and warranties in Article V of this
Agreement as to itself.

                                   WITNESSETH:

         WHEREAS, Compost owns 200 shares of the issued and outstanding shares
of common stock, no par value per share, of the Company, which constitutes all
of the issued and outstanding capital stock of the Company ("Company Common
Stock");

         WHEREAS, the Company is in the business of transporting (i) biosolids
by intermodal truck/rail hauling to land application sites for beneficial use
and to landfill sites, and (ii) other wastes, including but not limited to
incinerator ash, soils and municipal solid waste, to landfills and special
purpose disposal sites (collectively, the "Business");

         WHEREAS, the Purchaser desires to purchase from Compost, and Compost
desires to sell to the Purchaser, the Company Common Stock upon the terms and
conditions set forth herein; and

         WHEREAS, Compost is making certain representations, warranties and
indemnities herein, as an inducement to Purchaser to enter into this Agreement.

         NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements stated herein, the receipt
and sufficiency of which are hereby acknowledged, the Parties, intending to be
legally bound, covenant and agree as follows:

                                    ARTICLE I

                                   DEFINITIONS

         SECTION 1.1 ACCOUNTING TERMS. All accounting terms not specifically
defined herein shall be construed in accordance with generally accepted
accounting principles ("GAAP") and on a basis not inconsistent with those
applied in the preparation of the financial statements referred to in Section
5.5 hereof.

         SECTION 1.2 DEFINED TERMS. As used in this Agreement, certain words and
terms have the meanings ascribed to them in the Glossary attached hereto as
Exhibit A. Other capitalized terms have the meanings ascribed to them elsewhere
in this Agreement.


<PAGE>   7

                                   ARTICLE II

                                     CLOSING

         SECTION 2.1 CLOSING. Subject to the terms and provisions of Article IX,
the purchase and sale of the Company Common Stock (the "Closing") provided for
in this Agreement shall take place at a location mutually agreeable to the
parties hereto in New York City, as promptly as practicable (but in any event
within five (5) business days) following the date on which the last of the
conditions set forth in Article VIII is fulfilled or waived, or at such other
time and place as the parties shall agree; provided, however, that upon
agreement of the Parties the Closing may take place by telecopy. The date on
which the Closing occurs is referred to in this Agreement as the "Closing Date."

                                   ARTICLE III

                                  SALE OF STOCK

         SECTION 3.1 COMPANY COMMON STOCK. Subject to the terms and conditions
of this Agreement, Compost will sell, transfer and deliver to the Purchaser, and
the Purchaser will purchase, the Company Common Stock on the Closing Date.

         SECTION 3.2 PURCHASE PRICE.

                  (a) The aggregate purchase price (the "Purchase Price") for
the Company Common Stock and the representations, warranties, covenants and
agreements referenced herein and contemplated hereby shall be (i) cash equal to
Thirty-Seven Million Five Hundred Thousand Dollars ($37,500,000), less the
Adjustment Amount, payable to the order of and in the amounts listed on Schedule
3.2(a) (such Schedule 3.2(a) to be provided by Compost at least ten (10) days
prior to the Closing); and (ii) the earnout consideration, if any, due and
payable under the Earnout Agreement as defined in Section 3.4(a)(xii) below.

                  (b) The capitalized terms used in this Section shall have the
following meanings:

         "Adjustment Amount" means the sum of (1) the Company's Indebtedness as
of the Closing Date and (2) the amount, if any, by which the Company's Net
Working Capital as of the Closing Date is less than one million, four hundred
fifty thousand dollars ($1,450,000). The Adjustment Amount may be a negative
number, which will result in an increase of the Purchase Price.

         "Indebtedness" means the aggregate long-term indebtedness and other
long-term liabilities of the Company (including any premiums or fees resulting
from the prepayment of the Indebtedness) determined in accordance with GAAP. To
the extent Indebtedness of the Company is paid at Closing out of the Purchase
Price proceeds as set forth in Schedule 3.2(a) to be provided by Compost at
least ten (10) days prior to the Closing, such Indebtedness shall not be
deducted a second time from the Purchase Price by including such Indebtedness
within the Adjustment Amount calculation.

                                       2
<PAGE>   8

         "Net Working Capital" means the aggregate current assets of the Company
less the aggregate current liabilities of the Company determined in accordance
with GAAP.

                  (c) For purposes of determining the Adjustment Amount, (i) no
deduction shall be taken for the Company's current liabilities and Indebtedness
payable to Carter Machinery, Temple Elevators, Citicorp Dealer Finance and Ford
Motor Credit in the amounts set forth on Schedule 5.17 and (ii) the amounts in
current assets related to (i) IEM/Sealand, (ii) P. Edwards and (iii) FINOVA
financing costs shall be disregarded.

         SECTION 3.3 PURCHASE PRICE ADJUSTMENT.

                  (a) Prior to the Closing Date, Compost shall deliver to
Purchaser a worksheet which shall be attached as Exhibit B hereto, setting forth
a reasonable estimate of the Indebtedness and Net Working Capital as of the
Closing Date as well as a computation of the estimated Adjustment Amount (the
"Estimated Adjustment Amount"). The worksheet shall be prepared by Compost and
accepted by Purchaser in its reasonable discretion. If the Estimated Adjustment
Amount is a positive number, the amount payable in cash at Closing shall be
decreased in an amount equal to the Estimated Adjustment Amount. If the
Estimated Adjustment amount is a negative number, the amount payable in cash at
Closing shall be increased in an amount equal to the absolute value of the
Estimated Adjustment Amount.

                  (b) Within 90 days after the Closing, the Purchaser shall
cause the Company to prepare and deliver to Compost a balance sheet of the
Company as of the Closing Date (the "Closing Date Balance Sheet"), including a
computation of the actual Adjustment Amount of the Company as of the Closing
Date. The Closing Date Balance Sheet and the calculations of Indebtedness and
Net Working Capital shall be prepared in accordance with GAAP, and to the extent
consistent with GAAP, using the same accounting methods, policies, practices and
procedures with classifications, judgments and estimation methodologies
consistent with those used in preparation of the Company Financial Statements.
If within 15 calendar days following delivery of the Closing Date Balance Sheet
Compost does not object in writing thereto, Compost shall have been deemed to
have agreed to the Closing Date Balance Sheet. If Compost objects in writing to
the computation, then the Purchaser and Compost shall negotiate in good faith
and attempt to resolve their disagreement. Within the first fifteen calendar
days following the delivery of the Closing Date Balance Sheet and during the
period of any dispute within the contemplation of this Section 3.3(b), Compost
and other representatives of Compost shall have reasonable access during normal
business hours to all relevant books and records and employees of the Company to
the extent required to complete their review of the Closing Date Balance Sheet
and shall be permitted to review the working papers, if any, of the Company or
the Purchaser's Auditors relating to the Closing Date Balance Sheet. Purchaser
and Purchaser's Auditors shall cooperate with Compost and their representatives
in facilitating such review. Should such negotiations not result in an agreement
within 20 calendar days, then the matter shall be submitted to arbitration by an
independent accounting firm of national reputation mutually acceptable to the
Purchaser and Compost (the "Neutral Auditors"). Such arbitration shall be
governed by the rules provided in Sections 11.6(a), 11.6(b), 11.6(c), and
11.6(d) of this Agreement. If the Purchaser and Compost are unable to agree on
the Neutral Auditors, then they shall request the American Arbitration
Association to appoint the Neutral Auditors. All fees and expenses relating to
appointment of the Neutral Auditors and the work, if any, to be performed by the
Neutral Auditors will be borne equally by the Purchaser and Compost. The Parties
agree

                           OF COMPOST AND THE COMPANY

         Compost and the Company (to the extent the representation or warranty
is applicable to the Company), jointly and severally, represent and warrant to
Purchaser as follows:

         SECTION 5.1 ORGANIZATION AND QUALIFICATION. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the state of its incorporation and has the requisite corporate power and
authority to own, lease and operate its assets and properties and to carry on
its business as it is now being conducted. Except as set forth on Schedule 5.1,
the Company is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction in which the properties owned, leased, or
operated by it or the nature of the business conducted by it makes such
qualification necessary except for those jurisdictions in which failure to so
qualify would not have a Material Adverse Effect. True, accurate and complete
copies of the Company's articles of incorporation and bylaws, in each case as in
effect on the date hereof, including all amendments thereto, have heretofore
been delivered to Purchaser.

         SECTION 5.2 CAPITALIZATION.

                  (a) The authorized capital stock of the Company consists of
1,000 shares of Company Common Stock, of which 200 shares are issued and
outstanding, and no other shares of capital stock of the Company are issued and
outstanding. Except as set forth on Schedule 5.2, all of the issued and
outstanding shares of Company Common Stock were validly issued and are fully
paid, nonassessable and free of preemptive rights and are owned beneficially and
of record by Compost, free and clear of all restrictions, liens, claims and
encumbrances.

                  (b) Except as set forth on Schedule 5.2, there are no
outstanding (i) subscriptions, options, calls, contracts, commitments,
understandings, restrictions, arrangements, rights or warrants, including any
right of conversion or exchange under any outstanding security, debenture,
instrument or other agreement obligating the Company to issue, deliver or sell,
or cause to be issued, delivered or sold, additional shares of the capital stock
of the Company or obligating the Company to grant, extend or enter into any such
agreement or commitment or (ii) obligations of the Company to repurchase, redeem
or otherwise acquire any securities referred to in clause (i) above. Except as
set forth on Schedule 5.2, there are no voting trusts, proxies or other
agreements or understandings to which the Company is a party or is bound with
respect to the voting of any shares of capital stock of the Company.

                  (c) Wasteco and Longo entered into an agreement with Compost
in the form of Exhibit J hereto (the "Sharing Agreement") to alter certain
dividend provisions, to provide for additional redemption rights relative to the
Series A and Series C preferred stock of Compost and to provide collateral
security for undertaking to redeem stock under deferred circumstances. The
Sharing Agreement is effective to waive all rights of Wasteco and Longo to
acquire capital stock of the Company only upon the Closing. The Sharing
Agreement continues in full force and effect.

power and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. This Agreement has been approved by the Board
of Directors and shareholders of Compost and no other corporate proceedings on
the part of the Company or Compost are necessary to authorize the execution and
delivery of this Agreement or the consummation by Compost of the transactions
contemplated hereby. The only approval of the holders in any class or series of
Compost's or the Company's capital stock that is necessary to consummate the
transactions contemplated by this Agreement is the approval and adoption of this
Agreement by the holders of a majority of the votes entitled to be cast by
holders of the Compost Common Stock, with each share of Compost Common Stock
entitled to one vote per share (the "Compost Stockholders' Approval"). The
Compost Stockholders' Approval has been obtained by written consent effected in
accordance with Compost's articles of incorporation and bylaws and all
applicable laws. Contemporaneously with the execution and delivery of this
Agreement, the stockholders of Compost referenced in Exhibit K have executed and
delivered to the Purchaser the written consents and voting and proxy agreements
attached hereto as Exhibit K (collectively, the "Stockholder Consents"). The
Stockholder Consents are irrevocable and coupled with an interest. This
Agreement has been duly executed and delivered by Compost, and, assuming the due
authorization, execution and delivery hereof by Purchaser, constitutes a valid
and legally binding agreement of Compost, enforceable against Compost in
accordance with its terms.

                  (b) Except as set forth on Schedule 5.3, the execution and
delivery of this Agreement by Compost and the consummation by Compost of the
transactions contemplated hereby do not and will not violate or result in a
breach of any provision of, or constitute a default (or an event which, with
notice or lapse of time or both, would constitute a default) under, or result in
the termination of, or accelerate the performance required by, or result in a
right of termination or acceleration under, or result in the creation of any
lien, security interest, charge or encumbrance upon any of the properties or
assets of the Company under any of the terms, conditions or provisions of (i)
the articles of incorporation or bylaws of the Company or Compost, (ii) any
statute, law, ordinance, rule, regulation, judgment, decree, order, injunction,
writ, permit or license of any court or governmental authority applicable to the
Company or Compost, or any of their respective properties or assets, or (iii)
any note, bond, mortgage, indenture, deed of trust, license, franchise, permit,
concession, contract, lease or other instrument, obligation or agreement of any
kind to which the Company or Compost is now a party or by which the Company or
Compost or any of their respective properties or assets may be bound or
affected.

                  (c) Except with regard to a Hart-Scott-Rodino filing, no
consents and approvals, no declaration, filing or registration with, or notice
to, or authorization, consent or approval of, any governmental or regulatory
body or authority is necessary for the execution and delivery of this Agreement
by Compost or the consummation by Compost of the transactions contemplated
hereby.

         SECTION 5.4 SUBSIDIARIES. The Company does not have any Subsidiaries,
nor does the Company hold any equity interest in or control (directly or
indirectly, through the ownership of securities, by contract, by proxy, alone or
in combination with others, or otherwise) any corporation, limited liability
company, partnership, business organization or other Person.

or any Benefit Program, other than routine claims for benefits, and there are no
disputes or litigation pending or, to the knowledge of Compost and the Company,
threatened, with respect to any such Plans or Benefit Programs.

                  (b) Compost has heretofore delivered to Purchaser true and
correct copies of the following, if any:

                            (i) each Plan and each Benefit Program listed on
Schedule 5.13, all amendments thereto as of the date hereof and all current
summary plan descriptions provided to employees regarding the Plans and Benefit
Programs;

                            (ii) each trust agreement and annuity contract (or
any other funding instruments) pertaining to any of the Plans or Benefit
Programs, including all amendments to such documents to the date hereof;

                            (iii) each management or employment contract or
contract for personal services between the Company and any officer, consultant,
director, employee or independent contractor of the Company; and

                            (iv) a complete description of each other plan,
policy, contract, program, commitment or arrangement providing for bonuses,
deferred compensation, retirement payments, profit sharing, incentive pay,
commissions, hospitalization or medical expenses or insurance or any other
material benefits for any officer, consultant, director, annuitant, employee or
independent contractor of the Company as such or members of their families
(other than directors' and officers' liability policies), whether or not insured
but which are currently maintained by the Company or with respect to which the
Company currently has any liability (a "Benefit Program"). For purposes of this
Agreement, "Plan" means an "employee benefit plan" (as defined in Section 3(3)
of ERISA) which is or has been established or maintained, or to which
contributions are or have been made, by the Company or by any trade or business,
whether or not incorporated, which, together with the Company, is under common

<PAGE>   18


                  (c) Each other Plan and Benefit Program has been maintained
and administered in material compliance with its terms and in accordance with
all applicable laws, rules and regulations. The Company has no commitment or
obligation to establish or adopt any new or additional Plans or Benefit Programs
or to materially increase the benefits under any existing Plan or Benefit
Program.

                  (d) Except as set forth in Schedule 5.13, neither the
execution and delivery of this Agreement, nor the consummation of the
transactions contemplated hereby will (i) result in any payment to be made by
the Company, including, without limitation, severance, unemployment
compensation, golden parachute (defined in Section 280G of the Code) or
otherwise, becoming due to any employee of the Company, or (ii) increase any
benefits otherwise payable under any Plan or any Benefit Program.

                  (e) As of the date hereof, the Company does not sponsor any
simplified employee pension plans as described in Section 408(k) of the Code and
there are no claims against the Company for benefits relating to any such plans.

                  (f) The Company contributes to several multiemployer pension
plans and multiemployer welfare plans (collectively referred to as
"multiemployer plans") as more particularly disclosed on Schedule 5.13. None of
these multiemployer plans are in reorganization or insolvent (as defined in
ERISA Section 4241 and Section 4245). The Company is not liable for any
withdrawal liability from any multiemployer plan as of the Closing Date, other
than as shown on Schedule 5.6, and would not be subject to such liability if, as
of the Closing Date, the Company were to engage in a complete withdrawal (as
defined in ERISA Section 4203) or partial withdrawal (as defined in ERISA
Section 4205) from any such multiemployer plan. In addition, the Company has, or
will have as of the Closing, made all required contributions to the
multiemployer plans. The Company further represents and warrants that prior to
and as of the Closing Date, it has done nothing to incur withdrawal liability or
liability under any applicable provision of ERISA, either now or in the future
for any of the multiemployer plans to which it contributes.

         SECTION 5.14  EMPLOYEE AND LABOR MATTERS.

                  (a) Compost has provided Purchaser with a true and complete
list dated as of October 31, 1999 (the "Employee Schedule") of all employees of
the Company listing the title or position held, base salary or wage rate and any
bonuses, commissions, profit sharing, the Company vehicles, club memberships or
other material compensation or perquisites payable to such persons, all employee
benefits received by such employees and any other material terms of any written
agreement between such employees and the Company. As of the date of this
Agreement, the combined projected annual payroll for the calendar year ending
April 30, 1999 of the Company required to operate its business is not materially
different from that as listed on the Employee Schedule, and except as described
in Schedule 5.14, the Company has not entered into any agreement or agreements
pursuant to which the combined annual payroll of the Company for non-hourly
employees or the wage rates per hour for other employees, including projected
pay increases, overtime and fringe benefit costs, required to operate its
business (including all administrative and support personnel) would be greater
than as listed on the Employee Schedule.

                  (o) not take any action or omit to take any action, which
action or omission would result in a breach of any of the representations and
warranties set forth in this Agreement.

         SECTION 6.2 ACCESS TO INFORMATION; ENVIRONMENTAL DUE DILIGENCE. Compost
shall, and shall cause the Company to, give the Purchaser, its accountants,
counsel, financial advisors, and other representatives (the "Purchaser
Representatives") full access (and shall otherwise fully cooperate, including,
to the extent reasonably feasible, by making available copies of all, or
otherwise providing access to, the following documents which are susceptible to
photostatic reproduction) during normal business hours throughout the period
prior to Closing to all of the Company's properties, books, records (including,
but not limited to, Tax Returns and any and all records or documents which are
within the possession of governmental or regulatory authorities, agencies or
bodies, and the disclosure of which the Company can facilitate or control),
Contracts, premises, permits, Environmental Permits, licenses, Governmental
Authorizations, commitments of any nature (whether written or oral) and records,
and shall permit the Purchaser and Purchaser Representatives to make such
inspections (including without limitation environmental inspections, sampling,
and analysis) as they may require (at Purchaser's expense) and furnish to the
Purchaser and Purchaser Representatives during such period all such information
concerning the Company and its affairs as they may reasonably request. Compost
shall cause the Company to provide to Purchaser copies of all (aa) Permits, (bb)
reports or results of all inspections, audits, assessments, and analytical data
and (cc) such other information as Purchaser may reasonably request in the
possession or control of Compost regarding any of Company's current or prior
Business Facilities or operations and relating to (i) compliance with applicable
requirements of Environmental Laws or (ii) the exposure to, presence, release,
or any aspect of management, handling, or use of Materials of Environmental
Concern.

         SECTION 6.3 COMMERCIALLY REASONABLE EFFORTS. Subject to Compost's
rights under Section 7.3, Compost will use its commercially reasonable efforts

                  (a) Compost shall, as promptly as reasonably practicable after
the date hereof, distribute to its stockholders the Information Statement in
accordance with applicable federal and state law and with Compost's articles of
incorporation and bylaws. Compost shall provide a copy of the Information

                                   ARTICLE VII

              CERTAIN UNDERSTANDINGS AND AGREEMENTS OF THE PARTIES

         SECTION 7.1 CONFIDENTIALITY.

                  (a) Without the express written consent of all of the Parties,
each of the Parties agrees to maintain in confidence and not disclose to any
other Person (i) the terms of the transactions contemplated hereby or (ii) the
information delivered in connection with the proposed due diligence
investigation ("Confidential Information"), other than disclosures required or
appropriate to fairly describe the transactions involved in order to obtain the
approvals for the transactions contemplated hereby, disclosures to those
employees, professionals and advisors who have a need to know, disclosures of
information already available to the public or any other disclosures required by
applicable law or the rules of the NASD. If the Purchaser or Compost is at any
time requested or required (by oral questions, interrogatories, request for
information or documents, subpoena or other similar process) to disclose any
Confidential Information, such Party agrees to provide the other Parties prompt
notice of such request so that an appropriate protective order may be sought
and/or such other Party may waive the first Party's compliance with the terms of
this Section 7.1.

                  It is further agreed that, if in the absence of a protective
order or the receipt of a waiver hereunder a Party is nonetheless compelled to
disclose Confidential Information to any tribunal or else stand liable for
contempt or suffer other censure or penalty, such Party may disclose to such
tribunal without liability hereunder that portion of the Confidential
Information which it is compelled to disclose; provided, however, that such
Party shall give the other Party written notice of the information to be so
disclosed as far in advance of its disclosure as is practicable so that such
other Party may seek to obtain an order or other reliable assurance that
confidential treatment will be accorded to such information.

                  (b) If this Agreement shall be terminated, each party will (i)
redeliver all documents, work papers and other materials of any other party
relating to the transactions


                                       22
<PAGE>   28


contemplated hereby, or of a proprietary or confidential nature whether so
obtained before or after the execution of this Agreement, to the Party
furnishing the same, and (ii) destroy all documents, work papers and other
materials developed by its accountants, agents and employees in connection with
the transactions contemplated hereby which embody proprietary information or
trade secrets furnished by any Party hereto or deliver such documents, work
papers and other materials to the Party furnishing the same or excise such
information or secrets therefrom. If requested by Compost, the Purchaser will
certify that it has complied with this Section 7.1 and if requested by the
Purchaser, Compost will certify that it has complied with this Section.

         SECTION 7.2 FURTHER ASSURANCES. Compost and Purchaser shall execute and
deliver to the other, after the Closing Date, any other instrument which may be
requested by the other and which is reasonably appropriate to perfect or
evidence any of the sales, assignments, transfers or conveyances contemplated by
this Agreement or to obtain any consents or licenses necessary for Purchaser to
operate the Business in the manner operated by the Company prior to the Closing
Date provided, that Compost shall not be required to expend any funds to comply
with this Section unless the Purchaser agrees to promptly reimburse Compost for
such funds.

         SECTION 7.3 NO SOLICITATION.

                  (a) After the date hereof and prior to the earlier of the date
on which this Agreement terminates or the Closing Date, Compost shall not, and
it shall cause its subsidiaries, directors, officers, employees, financial and
other advisors, agents, representatives, Affiliates, and others working on its
behalf or at its direction (collectively, "Compost Representatives") not to,
initiate, solicit, encourage or facilitate offers, inquiries or proposals with
respect to, or furnish any information relating to or participate in any
negotiations or discussions concerning (i) any merger, reorganization, share
exchange, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving the Company, or any purchase or
sale of all or any substantial part of the business and properties of the
Company or any capital stock of the Company, or (ii) any merger, reorganization,
share exchange, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving Compost resulting in
any entity or person (including a "group" as defined in Section 13(d)(3) of the
Securities Exchange Act of 1934, or any comparable successor provisions)
becoming the beneficial owner of, or obtaining voting control over, a majority
of the then outstanding Compost stock (in each case, an "Acquisition Proposal"),
other than to Purchaser as contemplated by this Agreement.

                  (b) Notwithstanding Section 7.3(a), if Compost is not
otherwise in breach or violation of this Section 7.3, until the Closing Date,
the Board of Directors of Compost may (x) furnish information concerning the
Company to any Person indicating a desire to make an Acquisition Proposal
pursuant to appropriate confidentiality agreements, and (y) negotiate and
participate in discussions and negotiations with such Person concerning a
possible Acquisition Proposal, if in either case (x) or (y), (i) the Board of
Directors of Compost in good faith determines that such Acquisition Proposal (if
consummated pursuant to its terms) would result in a transaction more favorable
to the Compost stockholders than this transaction, and (ii) in the good faith
judgment of the Board of Directors of Compost, only after receipt of and based
upon advice from outside legal counsel to Compost, the failure to provide such
information or access or to engage in such discussions or negotiations would
cause the Board of Directors to violate its fiduciary duties to Compost's
stockholders under applicable law (any such acquisition proposal


                                       23
<PAGE>   29


meeting the conditions of clauses (i) and (ii) being hereinafter referred to as
a "Superior Proposal").

                  (c) Compost shall notify Purchaser within three business days
of the commencement of any discussions or negotiations between it or any Compost
Representative and any other Person concerning an Acquisition Proposal. Such
notice shall not be required to include any details with respect to such
discussions or negotiations or the identity of such Person. Compost agrees
immediately to cease and to cause to be terminated any activities, discussions
or negotiations conducted on or prior to the date of this Agreement with any
Person other than Purchaser with respect to an Acquisition Proposal.

         SECTION 7.4 EXPENSES AND FEES.

                  (a) Compost shall pay all costs and expenses incurred by the
Company and Compost in connection with this Agreement and the transactions
contemplated hereby, including, without limitation, any and all broker's
commissions, employee bonuses and the fees and expenses of the Company's and
Compost's attorneys and accountants. Purchaser shall pay all costs and expenses
incurred by Purchaser in connection with this Agreement and the transactions
contemplated hereby, including without limitation, the fees and expenses of
their attorneys and accountants and shall pay the filing fee required in
connection with the HSR Act filing.

                  (b) Notwithstanding anything to the contrary in Section
7.4(a), Compost agrees to pay to the Purchaser a fee equal to (i) the greater of
(x) $1 million or (y) the amount by which the consideration received or to be
received by Compost in the Acquisition Proposal exceeds the Purchase Price;
provided that such amount shall not exceed $3 million, plus (ii) all costs and
expenses incurred by Purchaser in connection with this Agreement and the
transactions contemplated hereby, including without limitation, all attorney's
fees, accountant's fees and broker's and investment banking fees and expenses,
if (x) Compost terminates this Agreement pursuant to Section 9.1(a)(v) or
Purchaser terminates this Agreement pursuant to Section 9.1(b)(iv) or (b)(v);
and (y) at any time prior to the date nine months after the termination of this
Agreement a definitive agreement with respect to any Acquisition Proposal shall
have been executed or any Acquisition Proposal shall have been consummated
within one year after the termination hereof. Any fee required to be paid by
Compost to the Purchaser pursuant to this Section 7.4(b) shall be due and
payable in cash on the date on which the closing of the Acquisition Proposal
occurs. This Section 7.4 (b) shall survive the termination of this Agreement
without a Closing, but shall not survive a Closing hereunder.

         SECTION 7.5 AGREEMENT TO COOPERATE. Subject to Compost's rights under
Section 7.3, prior to Closing and subject to the terms and conditions herein
provided, the Parties hereto shall use all commercially reasonable efforts to
take, or cause to be taken, all action and to do, or cause to be done, all
things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement,
including using their reasonable efforts to remove any injunctions or other
impediments or delays and to obtain (i) all necessary, proper or advisable
waivers, consents and approvals under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement,
and (ii) all necessary or appropriate waivers, consents or approvals of third
parties required in order to preserve material contractual relationships of the
Company.

         SECTION 7.6 PUBLIC STATEMENTS. The Parties shall obtain the written
consent of the other prior to issuing any press release or any written public

required by law or the NASD.

         SECTION 7.7 NOTIFICATION OF CERTAIN MATTERS. From the date hereof to
the Closing, each of Compost, the Company and the Purchaser agree to give prompt
notice to each other of, and to use their respective reasonable best efforts to
prevent or promptly remedy, (i) the occurrence or failure to occur or the
impending or threatened occurrence or failure to occur, of any event which would
be likely to cause any of its representations or warranties in this Agreement to
be untrue or inaccurate in any material respect and (ii) any material failure on
its part to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; provided, however, that the delivery
of any notice pursuant to this Section shall not limit or otherwise affect the
remedies available hereunder to the Party receiving such notice.

         SECTION 7.8 TAX ELECTION. The Purchaser shall not make a Section
338(h)(10) election under the Code with respect to the purchase of the Company
Common Stock.

         SECTION 7.9 NOTICE OF ENVIRONMENTAL CLAIMS. Up to and including the
Closing Date, Compost shall give prompt written notice to Purchaser of the
commencement of any Environmental Claim, or any non-routine inspection by any
Governmental Authority with responsibility for enforcing or implementing any
applicable Environmental Laws, and provide to Purchaser such information as
Purchaser may reasonably request regarding such Environmental Claim, any
developments in connection therewith, and, as applicable, Compost's anticipated
or actual response thereto.

         SECTION 7.10 STOCKHOLDER'S CONSENTS; SHARING AGREEMENT. Compost shall
not take (or cause to be taken) any action that would in any way terminate,
impede, frustrate, nullify or prevent the operation of such Stockholder
Consents. Up to and including the Closing Date, Compost shall fully satisfy and
comply with its agreements and obligations under the Sharing Agreement.

         SECTION 7.11 SUPPLEMENTS TO SCHEDULES. Each Party shall have the right
from time to time prior to the date five days prior to Closing to supplement or
amend its Schedules with respect to any matter hereafter arising which if
existing or known at the date of this Agreement would have been required to be
set forth or described in such Schedules. Any such supplemental or amended
disclosure shall be deemed to have cured any related breach of any
representation or warranty made in this Agreement, except that notwithstanding
the immediately preceding clause no such supplemental or amended disclosure
shall be deemed to have cured any such breach or violation of this Agreement
with respect to any matter required to have been disclosed as of the date of
this Agreement for purposes of determining whether or not the conditions to
Closing set forth in Section 8.3(b) hereof have been satisfied.

         SECTION 7.12 DIRECTOR AND OFFICER LIABILITY; INDEMNIFICATION. For six
(6) years after the Closing Date, Compost will indemnify and hold harmless the

<PAGE>   31


Company in respect of acts or omissions occurring on or prior to the Closing
Date to the same extent and in the same manner provided under any agreements and
the Company's certificate of incorporation, bylaws and similar organizational
documents in effect on the Closing Date.

         SECTION 7.13 EARNOUT COVENANTS. The Purchaser agrees to comply with the
following covenants commencing with the Closing Date and ending upon the earlier
of (i) April 1, 2003, and (ii) satisfaction of all amounts due and owing under
the Earnout Agreement.

                  (a) The Purchaser shall not directly, or indirectly through
any of its Subsidiaries, own or operate a Rail Transportation Business east of
the Mississippi River other than the Company and an Acquired Business. For
purposes of this Agreement, an "Acquired Business" is a business or company, or
group of related businesses or companies, acquired in a single transaction and
designated as an "Acquired Business" by the Purchaser. The Purchaser shall be
entitled to designate only one Acquired Business and such Acquired Business
shall not own in the aggregate more than 100 railcars. For purposes of this
Section, "Rail Transportation Business" shall mean the business of transporting
biosolids, incinerator ash and/or soils by intermodal rail for landfilling or
for land application or beneficial reuse. The Purchaser shall allow the Company
the option to provide Rail Transportation Business services to Synagro and its
Subsidiaries (other than any Acquired Business) with respect to transportation
originating east of the Mississippi River on the same terms as proposed to be
provided by a third party, unless otherwise precluded by contract, Governmental
Authority or lack of Company capacity. The Acquired Business shall be entitled
to replace railcars no longer in use with similar railcars but shall be
precluded from increasing the aggregate number of railcars owned by the Acquired
Business by more than 10% of the number owned at the time Purchaser acquires the
Acquired Business. An Acquired Business shall be able to bid on new contracts
utilizing its railcars to replace lost contracts, provided that those contracts
are for services consistent with the business of such Acquired Business. There
shall be no restrictions on the Acquired Business with respect to any business
not utilizing its railcars.

                  (b) The Company shall be permitted to provide Rail
Transportation Business services as a subcontractor on a non-exclusive basis to
third party bidders at the same price such services would be provided to the
Purchaser or its Subsidiaries regardless of whether Purchaser or its Affiliates
also bid the same contract or services.

                  (c) Compost and the Purchaser agree that the Company shall be
subject to the normal Purchaser corporate approval process with respect to new
projects, contracts, capital requests and other similar matters.

                  (d) All new business developed by Longo and approved by
Purchaser in accordance with Section 7.13(c) above for which Longo is otherwise
compensated by a performance bonus under his employment arrangements shall be
conducted by the Company.

                  (e) The Company shall be permitted to maintain operational
management personnel and equipment consistent with the Company levels at January
31, 2000. Operational management personnel and equipment may only be leased or
otherwise assigned or transferred to Purchaser or its Subsidiaries upon terms
consented to by the Purchaser and Longo at the time of such lease, assignment or
transfer, which consents shall not be unreasonably withheld.

the Earnout Agreement in a fair and equitable manner.

                  (g) Notwithstanding the survival limitations set forth in
Section 11.1 of this Agreement, the Purchaser's liability for failure to comply
with the covenants and agreements set forth in this Section 7.13 shall survive
until the satisfaction of all amounts due and owing under the Earnout Agreement.

                              CONDITIONS TO CLOSING

         In determining whether a Party has performed an agreement or covenant
referred to in Section 7.7, or Article 8 or 9 in all material respects or
whether a representation or warranty referred to in Section 7.7, or Article 8 or
9 is true and correct in all material respects, the materiality qualification

Agreement;

                           (i)   if the representations and warranties of
Compost shall fail to be true and correct in all material respects on and as of
the date made or, except in the case of any such representations and warranties
made as of a specified date, on and as of any subsequent date as if made at and
as of such subsequent date and such failure shall not have been cured in all
material respects within 30 days after written notice of such failure is given
to Compost by Purchaser;

                           (ii)  if the transactions contemplated hereby are not
completed by May 31, 2000;

                           (iii) if the transactions contemplated hereby are
enjoined by a final, unappealable court order;

                           (iv)  if Compost (A) fails to perform in any material
respect any of its covenants in this Agreement and (B) does not cure such
default in all material respects within 15 days after notice of such default is
given to Compost by Purchaser; or

                           (v)   if (i) Compost shall have delivered the notice
described in Section 9.1(a)(v), (ii) the Board of Directors of Compost shall
have approved or recommended another Acquisition Proposal, or (iii) Compost
shall have engaged in negotiations with a third party after the date hereof with
respect to any Acquisition Proposal and shall not have fully and unconditionally
rejected such proposal within seven (7) calendar days of first engaging in any
negotiations with respect to such Acquisition Proposal; and

                           (vi) if Purchaser after good faith efforts to obtain
financing shall not have notified Compost in writing after the date of this
Agreement and on or prior to April 14, 2000, that Purchaser has obtained
financing in an amount and pursuant to terms satisfactory to Purchaser to
consummate the transactions contemplated in this Agreement.

                  (c) Compost and Purchaser mutually agree in writing.

         SECTION 9.2 EFFECT OF TERMINATION. The following provisions shall apply
in the event of a termination of the Agreement:

                  (a) If this Agreement is terminated by either Purchaser or
Compost pursuant to the provisions of Section 9.1, this Agreement shall
forthwith become void and there shall be no further obligations on the part of
Compost or Purchaser or their stockholders, directors, officers, employees,
agents or representatives (except as set forth in Sections 7.1, 7.3, 7.4, 11.5
and 11.6, and Article X, each of which shall survive termination in its
entirety). Notwithstanding


                                       30
<PAGE>   36


the preceding sentence or any other provision set forth herein, nothing in this
Section 9.2 shall relieve any party from liability for any breach of this
Agreement or from the remedies set forth in Section 9.2(b).

                  (b) The Parties hereto acknowledge and agree that Purchaser,
as a result of the actual damages Purchaser would sustain by reason of the
negligent or willful failure of Compost to perform its obligations hereunder,
could not be made whole by monetary damages. It is accordingly agreed that
Purchaser shall have the right to elect, in addition to any and all other
remedies at law or in equity, to enforce specific performance under this
Agreement. Compost waives the defense in any such action for specific
performance that a remedy at law would be adequate.

         SECTION 9.3 EXTENSIONS; WAIVER. At any time prior to the Closing Date,
the Parties may (a) extend the time for the performance of any of the
obligations or other acts of the other Parties, (b) waive any inaccuracies in
the representations and warranties contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any of the agreements or
conditions herein. Any agreement on the part of a Party to any such extension or
waiver shall be valid if set forth in an instrument in writing signed by or on
behalf of such Party.

                                    ARTICLE X

                   INDEMNIFICATION AND LIMITATION ON LIABILITY

         SECTION 10.1 COMPOST'S INDEMNITY OBLIGATIONS. Compost shall indemnify
and hold harmless the Company (after the Closing), Purchaser and the Company's

without limitation, Environmental Claims), actions, causes of action,
arbitrations, proceedings, losses, damages, remediations, liabilities, strict
liabilities, judgments, fines, penalties and expenses (including, without

Amounts") paid, imposed on or incurred by a Purchaser Indemnified Party,
directly or indirectly, (i) relating to, resulting from or arising out of (a)
any breach or misrepresentation in any of the representations and warranties
made by or on behalf of Compost or the Company (on or before the Closing) in
this Agreement, including without limitation with respect to environmental
matters, or any certificate or instrument contemplated by and delivered in
connection with this Agreement, (b) any violation or breach by Compost or the
Company (on or before the Closing) of, or default by Compost or the Company (on
or before the Closing) under, the terms of this Agreement or any certificate or

any amounts for which the Purchaser Indemnified Parties become liable as a
result of any bankruptcy filed by Compost (whether voluntary or involuntary) on

for which a Purchaser Indemnified Party may become liable as a result of any

a Purchaser Indemnified Party may become liable relating to the items listed on

articles of incorporation or bylaws


                                       31
<PAGE>   37


of the Company) that is not covered by the insurance referenced in Section
8.3(i) of this Agreement, or (g) the lawsuit listed as item no. 1 on Schedule
5.8 or (ii) relating to, resulting from or arising out of any allegation of a
third party of the events described in Sections 10.1(a), (b), (c) , (d), (e),
(f) or (g) above. For purposes of this Section 10.1, Indemnified Amounts shall
include without limitation those Indemnified Amounts ARISING OUT OF THE STRICT
LIABILITY (INCLUDING BUT NOT LIMITED TO STRICT LIABILITY ARISING PURSUANT TO
ENVIRONMENTAL LAWS) OF ANY PARTY, INCLUDING ANY PURCHASER INDEMNIFIED PARTY OR
THE NEGLIGENCE OF THE COMPANY OR THE COMPANY'S OFFICERS, DIRECTORS,
STOCKHOLDERS, EMPLOYEES, AGENTS, REPRESENTATIVES OR AFFILIATES, WHETHER SUCH
NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, ACTIVE OR PASSIVE.

         SECTION 10.2 PURCHASER'S INDEMNITY OBLIGATIONS. Purchaser shall
indemnify and hold harmless the Company (before the Closing), Compost and the
Company's (before the Closing) and Compost's officers, directors, stockholders,
employees, agents, representatives and Affiliates (each a "Seller Indemnified
Party") from and against any and all Indemnified Amounts paid, imposed on or
incurred by a Seller Indemnified Party, directly or indirectly, (i) relating to,
resulting from or arising out of (a) any breach or misrepresentation in any of
the representations and warranties made by or on behalf of Purchaser in this
Agreement or any certificate or instrument contemplated by and delivered in
connection with this Agreement or (b) any violation or breach by Purchaser of or
default by Purchaser under the terms of this Agreement or any certificate or
instrument contemplated by and delivered in connection with this Agreement, or
(ii) relating to, resulting from or arising out of any allegation of a third
party of the events described in Sections 10.2(a) or (b) above.

         SECTION 10.3 INDEMNIFICATION PROCEDURES. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                  (a) Any of the Parties claiming indemnification under this
Agreement (an "Indemnified Party") shall with reasonable promptness (i) notify
the Party from whom indemnification is sought (the "Indemnifying Party") of any
third-party claim or claims asserted against the Indemnified Party ("Third-Party
Claim") for which indemnification is sought and (ii) transmit to the
Indemnifying Party a copy of all papers served with respect to such claim (if
any) and a written notice ("Claim Notice") containing a description in
reasonable detail of the nature of the Third-Party Claim, an estimate of the
amount of damages attributable to the Third-Party Claim to the extent feasible
(which estimate shall not be conclusive of the final amount of such claim) and
the basis of the Indemnified Party's request for indemnification under this
Agreement.

                  Within 15 days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(i) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party with respect to such Third-Party Claim and (ii) whether the
Indemnifying Party desires, at the sole cost and expense of the Indemnifying
Party, to defend the Indemnified Party against such Third Party Claim.

                  If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third-Party Claim, then the Indemnifying Party shall have the
right to defend, at its sole cost and expense, such Third-


                                       32
<PAGE>   38


Party Claim by all appropriate proceedings, which proceedings shall be
prosecuted diligently by the Indemnifying Party to a final conclusion or settled
at the discretion of the Indemnifying Party in accordance with this Section
10.3(a). The Indemnifying Party shall have full control of such defense and
proceedings. The Indemnified Party is hereby authorized, at the sole cost and
expense of the Indemnifying Party, to file, during the Election Period, any
motion, answer or other pleadings that the Indemnified Party shall reasonably
deem necessary or appropriate to protect its interests. If requested by the
Indemnifying Party, the Indemnified Party agrees to cooperate with the
Indemnifying Party and its counsel in contesting any Third-Party Claim that the
Indemnifying Party elects to contest, including, without limitation, the making
of any related counterclaim against the person asserting the Third-Party Claim
or any cross-complaint against any person. Except as otherwise provided herein,
the Indemnified Party may participate in, but not control, any defense or
settlement of any Third-Party Claim controlled by the Indemnifying Party
pursuant to this Section 10.3 and shall bear its own costs and expenses with
respect to such participation.

                  If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to the preceding paragraph, or if the
Indemnifying Party elects to defend the Indemnified Party but fails to prosecute
or settle the Third Party Claim as herein provided or if the Indemnified Party
reasonably objects to such election on the grounds that counsel for such
Indemnifying Party cannot represent both the Indemnified Party and the
Indemnifying Parties because such representation would be reasonably likely to
result in a conflict of interest, then the Indemnified Party shall have the
right to defend, at the sole cost and expense of the Indemnifying Party, the
Third Party Claim by all appropriate proceedings, which proceedings shall be
promptly and vigorously prosecuted by the Indemnified Party to a final
conclusion or settled. In such a situation, the Indemnified Party shall have
full control of such defense and proceedings and the Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the
Indemnified Party pursuant to this Section 10.3, and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation.

                  The Indemnifying Party shall not settle or compromise any
Third Party Claim unless (i) the terms of such compromise or settlement require
no more than the payment of money (i.e., such compromise or settlement does not
require the Indemnified Party to admit any wrongdoing or take or refrain from
taking any action), (ii) the full amount of such monetary compromise or
settlement will be paid by the Indemnifying Party, and (iii) the Indemnified
Party receives as part of such settlement a legal, binding and enforceable
unconditional satisfaction and/or release, in form and substance reasonably
satisfactory to it, providing that such Third-Party Claim and any claimed
liability of the Indemnified Party with respect thereto is being fully satisfied
by reason of such compromise or settlement and that the Indemnified Party is
being released from any and all obligations or liabilities it may have with
respect thereto. Except as provided in Section 10.3(b) of this Agreement, the
Indemnified Party shall not settle or admit liability to any Third-Party Claim
without the prior written consent of the Indemnifying Party unless (x) the
Indemnifying Party has disputed its potential liability to the Indemnified
Party, and such dispute either has not been resolved or has been resolved in
favor of the Indemnifying Party or (y) the Indemnifying Party has failed to
respond to the Indemnified Party's Claim Notice.

                  (b) Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding or claim may adversely affect it or


                                       33
<PAGE>   39


its Affiliates other than as a result (or in excess) of monetary damages for
which it would be entitled to indemnification under this Agreement, the
Indemnified Party may, by notice to the indemnifying party, assume the exclusive
right to defend, compromise, or settle such Proceeding or claim, but for the
purposes of claiming against the Earnout Agreement the Indemnifying Party will
not be bound by any determination of a Proceeding or claim so defended or any
compromise or settlement effected without its consent (which may not be
unreasonably withheld).

                  (c) If any Indemnified Party should have a claim against any
Indemnifying Party hereunder that does not involve a Third-Party Claim, the
Indemnified Party shall transmit to the Indemnifying Party a written notice (the
"Indemnity Notice") describing in reasonable detail the nature of the claim, an
estimate of the amount of damages attributable to such claim to the extent
feasible (which estimate shall not be conclusive of the final amount of such
claim) and the basis of the Indemnified Party's request for indemnification
under this Agreement. As to such a claim, agreement or arbitration shall
determine the Indemnified Amount; provided, however, that nothing herein shall
restrict the Purchaser's right to offset under Section 10.6 of this Agreement.

         SECTION 10.4 LIMITATION OF COMPOST'S LIABILITY.

                  (a) Notwithstanding anything to the contrary contained in this
Agreement, except (i) for the aggregate liability of Compost for any event or
occurrence giving rise to Compost being required to indemnify Purchaser
Indemnified Parties pursuant to Section 10.1(i)(f) of this Agreement (and
Section 10.1(ii) as it relates to Section 10.1(i)(f)) which shall be unlimited,
(ii) as provided in Sections 7.4(b) and 9.2 of this Agreement, and (iii) for
claims of fraud or willful misconduct, the sole remedy of the Purchaser for any
breach or violation under this Agreement shall be limited to the rights of the
Purchaser Indemnified Parties under this Article X and under the Earnout
Agreement, and the aggregate liability for all events or occurrences giving rise
to Compost being required to indemnify the Purchaser Indemnified Parties
pursuant to Section 10.1 (together with Compost's exposure in the maximum amount
of $5,000,000 for the Company's failure to satisfy the EBITDA targets under the
Earnout Agreement) shall be limited to $9,000,000.

                  (b) Purchaser Indemnified Parties are entitled to
indemnification pursuant to Section 10.1(i)(a) through (c) (and Section 10.1(ii)
as it relates to Section 10.1(i)(a) through (c)) only if the amount of any
Indemnified Amount, individually or in the aggregate with all other Indemnified
Amounts hereunder (including the first $162,500 of Indemnified Amounts under
Section 10.1(i)(g) and Section 10.1(ii) as it relates to Section 10.1(i)(g), as
referenced in the next sentence), exceeds Four Hundred Fifty Thousand Dollars
($450,000), and then only to the extent of such excess. Purchaser Indemnified
Parties are entitled to indemnification pursuant to Section 10.1(i)(g) (and
Section 10.1(ii) as it relates to Section 10.1(i)(g)) only if the Indemnified
Amounts under such sections exceed $162,500 in the aggregate, and then only to
the extent of such excess. Such deductibles shall not be applicable to claims
under Section 7.4(b) and Indemnified Amounts under Sections 10.1(i)(d) through
(f) and Section 10.1(ii) as it relates to Section 10.1(i)(d) through (f).

         SECTION 10.5 LIMITATION OF PURCHASER'S LIABILITY.

                  (a) Notwithstanding anything to the contrary contained in this
Agreement, the sole remedy of Compost for any breach or violation by Purchaser
under this Agreement shall be limited to the rights of Compost under this
Article X, and the aggregate liability of Purchaser for all events or
occurrences giving rise to Purchaser being required to indemnify Seller
Indemnified Parties pursuant to Section 10.2 shall be limited to $1,000,000.

                  (b) Seller Indemnified Parties are entitled to indemnification
pursuant to Section 10.2 only if the amount of any Indemnified Amount,
individually or in the aggregate with all other Indemnified Amounts hereunder,
exceeds Four Hundred Fifty Thousand Dollars ($450,000), and then only to the
extent of such excess.

         SECTION 10.6 RIGHT OF OFFSET. Upon written notice to Compost under the
Earnout Agreement specifying in reasonable detail its justification therefore,
the Purchaser may offset the amount of any Indemnified Amount determined by
litigation, arbitration or settlement under Section 10.3 to be owed to Purchaser
against any amount owed by the Purchaser to Compost under the Earnout Agreement.

         SECTION 10.7 ESCROW. If there exists a bona fide dispute at the time
payment of the earnout consideration is due under the Earnout Agreement
regarding a claim by a Purchaser Indemnified Party or with respect to the right
of the Purchaser to offset against amounts due under the Earnout Agreement, the
Parties agree that at such time, the Purchaser shall deposit a portion of such
earnout consideration due and payable equal to the amount in dispute into an
interest bearing escrow account ("Escrow Account"), pending resolution of such
dispute. Interest on the Escrow Account shall accrue for the benefit of the
Party to whom the Escrow Account proceeds are released upon resolution of such
dispute; provided, that if the Escrow Account proceeds are released to more than
one Party, the interest shall be prorated among the Parties based on the amounts
released to the Parties. Upon resolution of the dispute, the Purchaser shall be
entitled to exercise its right of set-off as and in the manner provided in
Section 10.6 of this Agreement against the proceeds in the Escrow Account.
Immediately after resolution of the dispute, the Escrow Agent shall immediately
release and deliver to the payee under the Earnout Agreement all of the
remaining Escrow Account proceeds.

                               GENERAL PROVISIONS

         SECTION 11.1 SURVIVAL. The representations, warranties, covenants and
agreements (including, but not limited to, indemnification obligations) set

period of two (2) years following the date of Closing; provided, however, that
(i) in the case of all such representations, warranties, covenants and
agreements (including, but not limited to, indemnification obligations) there
shall be no such termination with respect to any such representation, warranty,
covenant or agreement to the extent a bona fide claim has been asserted by
written notice of such claim delivered to the Party or Parties making such
representation, warranty, covenant or agreement prior to the expiration of the
survival period, (ii) Compost's covenants and agreements set forth in Section
7.12 and the indemnification

<PAGE>   41

Closing, (iii) the indemnification obligations set forth in Section 10.1(i)(g)
(and Section 10.1(ii) as it relates to Section 10.1(i)(g)) shall survive the
Closing until 90 days after the disputes referenced in Section 10.1(i)(g) are
finally resolved by litigation, arbitration or settlement, and (iv) the
representations and warranties of the Company shall not survive the Closing with
respect to the Company but shall survive for purposes of Compost's indemnity
obligations under Section 10.1 as set forth in this Section 11.1.

         SECTION 11.3 INTERPRETATION. The headings contained in this Agreement
are for reference purposes only and shall not affect in any way the
interpretation of this Agreement. In


                                       36
<PAGE>   42


this Agreement, unless a contrary intention is specifically set forth, (i) the
words "herein", "hereof" and "hereunder" and other words of similar import refer
to this Agreement as a whole and not to any particular Article, Section or other
subdivision and (ii) reference to any Article or Section means such Article or
Section hereof. No provision of this Agreement shall be interpreted or construed
against any Party solely because such Party or its legal representative drafted
such provision.

         SECTION 11.4 MISCELLANEOUS. This Agreement (including the documents and
instruments referred to herein and the Schedules and Exhibits attached hereto)
(a) constitutes the entire agreement and supersedes all other prior agreements
and understandings, both written and oral, among the Parties, or any of them,
with respect to the subject matter hereof, and (b) shall not be assigned by
operation of law or otherwise except that Purchaser may assign this Agreement to
any other wholly-owned Subsidiary of Purchaser, but no such assignment shall
relieve the Purchaser of its obligations hereunder.

         SECTION 11.5 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED IN ALL
RESPECTS, INCLUDING VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS OF THE
STATE OF TEXAS APPLICABLE TO CONTRACTS EXECUTED AND TO BE PERFORMED WHOLLY
WITHIN SUCH STATE.

         SECTION 11.6 BINDING ARBITRATION.

                  (a) General. Notwithstanding any provision of this Agreement
to the contrary, upon the request of any Party (defined for the purpose of this
provision to include Affiliates, principals and agents of any such Party), any
dispute, controversy or claim arising out of, relating to, or in connection
with, this Agreement or any agreement executed in connection herewith or
contemplated hereby, or the breach, termination, interpretation, or validity
hereof or thereof (hereinafter referred to as a "Dispute"), shall be finally
resolved by mandatory and binding arbitration in accordance with the terms
hereof. Any Party may bring an action in court to compel arbitration of any
Dispute. Any Party who fails or refuses to submit any Dispute to binding
arbitration following a lawful demand by the opposing Party shall bear all costs
and expenses incurred by the opposing Party in compelling arbitration of such
Dispute.

<PAGE>   43


                  (b) Governing Rules. The arbitration shall be conducted in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association in effect at the time of the arbitration, except as they may be
modified herein or by mutual agreement of the Parties. The arbitration and this
clause shall be governed by the Federal Arbitration Act, 9 U.S.C. Sections 1 et
seq. (the "Federal Arbitration Act"). The arbitrator shall award all reasonable
and necessary costs (including the reasonable fees and expenses of counsel)
incurred in conducting the arbitration to the prevailing Party in any such
Dispute. The Parties expressly waive all rights whatsoever to file an appeal
against or otherwise to challenge any award by the arbitrators hereunder;
provided, that the foregoing shall not limit the rights of any Party to bring a
proceeding in any applicable jurisdiction to confirm, enforce or enter judgment
upon such award (and the rights of the other Party, if such proceeding is
brought, to contest such confirmation, enforcement or entry of judgment, but
only to the extent permitted by the Federal Arbitration Act).

                  (c) No Waiver; Preservation of Remedies. No provision of, nor
the exercise of any rights under this Agreement shall limit the right of any
Party to apply for injunctive relief or similar equitable relief with respect to
the enforcement of this Agreement or any agreement executed in connection
herewith or contemplated hereby, and any such action shall not be deemed an
election of remedies. Such rights can be exercised at any time except to the
extent such action is contrary to a final award or decision in any arbitration
proceeding. The Parties agree that irreparable damage would occur if any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
Parties shall be entitled to an injunction or injunctions to prevent breaches of
this Agreement and to enforce specifically the terms and provisions hereof. The
institution and maintenance of an action for injunctive relief or similar
equitable relief shall not constitute a waiver of the right of any Party,
including without limitation the plaintiff, to submit any Dispute to arbitration
nor render inapplicable the compulsory arbitration provisions of this Agreement.

                  (d) Arbitration Proceeding. In addition to the authority
conferred on the arbitration tribunal by the rules specified above, the
arbitration tribunal shall have the authority to order reasonable discovery,
including the depositions of party witnesses and production of documents. The
arbitral award shall be in writing, state the reasons for the award, and be
final and binding on the Parties with no right of appeal. All statutes of
limitations that would otherwise be applicable shall apply to any arbitration
proceeding. Any attorney-client privilege and other protection against
disclosure of confidential information, including without limitation any
protection afforded the work-product of any attorney, that could otherwise be
claimed by any Party shall be available to and may be claimed by any such Party
in any arbitration proceeding. No Party waives any attorney-client privilege or
any other protection against disclosure of confidential information by reason of
anything contained in or done pursuant to or in connection with this Agreement.
Each Party agrees to keep all Disputes and arbitration proceedings strictly
confidential, except for disclosures of information to the Parties' legal
counsel or auditors or those required by applicable law. The arbitrators shall
determine the matters in dispute in accordance with the substantive law of
Texas, without regard to conflict of law rules. The obligation to arbitrate any
dispute shall be binding upon the successors and assigns of each of the Parties.

                  (e) Appointment of Arbitrators. The arbitration shall be
conducted by three (3) arbitrators. The Party initiating arbitration (the
"Claimant") shall appoint its arbitrator in its request for arbitration (the
"Request"). The other Party (the "Respondent") shall appoint its arbitrator
within thirty (30) days after receipt of the Request and shall notify the

arbitrator within such thirty (30) day period, the arbitrator named in the
Request shall decide the controversy or claim as sole arbitrator. Otherwise, the
two (2) arbitrators appointed by the Parties shall appoint a third (3rd)
arbitrator within thirty (30) days after the Respondent has notified Claimant of
the appointment of the Respondent's arbitrator. When the third (3rd) arbitrator
has accepted the appointment, the two (2) Party-appointed arbitrators shall
promptly notify the Parties of the appointment. If the two (2) arbitrators
appointed by the Parties fail to appoint a third (3rd) arbitrator and so to
notify the Parties within the time period prescribed above, then the appointment
of the third (3rd) arbitrator shall be made by the American Arbitration
Association, which shall promptly notify the Parties of the appointment. The
third (3rd) arbitrator shall act as Chair of the panel.

signature and in two or more counterparts, each of which shall be deemed to be
an original, but all of which shall constitute one and the same agreement.

         SECTION 11.9 PARTIES IN INTEREST. This Agreement shall be binding upon
and inure solely to the benefit of each Party hereto, and nothing in this
Agreement, express or implied, is intended to confer upon any other person any
rights or remedies of any nature whatsoever under or by reason of this
Agreement.

         SECTION 11.10 VALIDITY. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provisions of this Agreement, which shall remain in full force and
effect.
