         1. Earthcare Resource Management of Florida, Inc., a Florida
corporation, Earthcare Resource Management of South Florida, Inc. (a Florida
corporation) and Earthcare Acquisition Sub, Inc., (an Illinois corporation) as
co-borrowers (hereinafter collectively referred to as "Borrower") has executed
in favor of Lender a certain convertible debenture of even date herewith,
payable to the order of Lender in the aggregate principal amount of $1,500,000

in substitution, renewal or extension therefor or thereof, in whole or in part,
being herein collectively called the "Note").

         2. The Note was executed pursuant to a Loan Agreement of even date
herewith, (herein, as from time to time amended, supplemented or restated,
called the "Credit Agreement"), by and between Borrower, Lender and Parent,
pursuant to which Lender has agreed to advance funds to Borrower under the Note.

         3. It is a condition precedent to Lender's obligation to advance funds
pursuant to the Credit Agreement that Guarantor shall execute and deliver to
Lender a satisfactory guaranty of Borrower's obligations under the Note and the

Company ("Parent"), a Delaware corporation and the ultimate parent of Borrower.

will inure to Guarantor from Lender's advances of funds to Borrower under the
Credit Agreement, and of Ten Dollars and other good and valuable consideration,

hereby agrees with Lender as follows:

reason of which, or pursuant to which any or all of the Obligations are
evidenced, governed, secured, or otherwise dealt with, and all other documents,

claims are subordinated to the Obligations.

         Section 2. Guaranty.

         (a) Guarantor hereby irrevocably, absolutely, and unconditionally
guarantees to Lender the prompt, complete, and full payment when due, and no
matter how the same shall become due, of:

                  (i) the Note, including all principal, all interest thereon
         and all other sums payable thereunder; and

                  (ii) All other sums payable under the other Obligation
         Documents, whether for principal, interest, fees or otherwise; and

                  (iii) Any and all other indebtedness or liabilities which
         Borrower may at any time owe to Lender, whether incurred heretofore or
         hereafter or concurrently herewith, voluntarily or involuntarily,
         whether owed alone or with others, whether fixed, contingent, absolute,
         inchoate, liquidated or unliquidated, whether such indebtedness or
         liability arises by notes, discounts, overdrafts, open account
         indebtedness or in any other manner whatsoever, and including interest,
         attorneys' fees and collection costs as may be provided by law or in
         any instrument or agreement evidencing any such indebtedness or
         liability.

Without limiting the generality of the foregoing, Guarantor's liability
hereunder shall extend to and include all post-petition interest, expenses, and
other duties and liabilities of Borrower described above in this subsection (a),
or below in the following subsection (b), which would be owed by Borrower but
for the fact that they are unenforceable or not allowable due to the existence
of a bankruptcy, reorganization, or similar proceeding involving Borrower.

         (b) Guarantor hereby irrevocably, absolutely, and unconditionally
guarantees to Lender the prompt, complete and full performance, when due, and no
matter how the same shall become due,

<PAGE>   3

of all obligations and undertakings of Borrower to Lender under, by reason of,
or pursuant to any of the Obligation Documents.

         (c) If Borrower shall for any reason fail to pay any Obligation, as and
when such Obligation shall become due and payable, whether at its stated
maturity, as a result of the exercise of any power to accelerate, or otherwise,
Guarantor will, upon demand by Lender, pay such Obligation in full to Lender. If
Borrower shall for any reason fail to perform promptly any Obligation, Guarantor
will, upon demand by Lender, cause such Obligation to be performed or, if
specified by Lender, provide sufficient funds, in such amount and manner as
Lender shall in good faith determine, for the prompt, full and faithful
performance of such Obligation by Lender or such other Person as Lender shall
designate.

         (d) If either Borrower or Guarantor fails to pay or perform any
Obligation as described in the immediately preceding subsections (a), (b), or
(c) Guarantor will incur the additional obligation to pay to Lender, and
Guarantor will forthwith upon demand by Lender pay to Lender, the amount of any
and all expenses, including fees and disbursements of Lender's counsel and of
any experts or agents retained by Lender, which Lender may incur as a result of
such failure.

         (e) As between Guarantor and Lender, this Guaranty shall be considered
a primary and liquidated liability of Guarantor.

         Section 3. Unconditional Guaranty.

         (a) No action that Lender may take or omit to take in connection with
any of the Obligation Documents, any of the Obligations (or any other
indebtedness owing by Borrower to Lender), or any Security, and no course of
dealing of Lender with any Obligor or any other Person, shall release or
diminish Guarantor's obligations, liabilities, agreements or duties hereunder,
affect this Guaranty in any way, or afford Guarantor any recourse against
Lender, regardless of whether any such action or inaction may increase any risks
to or liabilities of Lender or any Obligor or increase any risk to or diminish
any safeguard of any Security. Without limiting the foregoing, Guarantor hereby
expressly agrees that Lender may, from time to time, without notice to or the
consent of Guarantor, do any or all of the following:

                  (i) Amend, change or modify, in whole or in part, any one or
         more of the Obligation Documents and give or refuse to give any waivers
         or other indulgences with respect thereto.

                  (ii) Neglect, delay, fail, or refuse to take or prosecute any
         action for the collection or enforcement of any of the Obligations, to
         foreclose or take or prosecute any action in connection with any
         Security or Obligation Document, to bring suit against any Obligor or
         any other Person, or to take any other action concerning the
         Obligations or the Obligation Documents.

                  (iii) Accelerate, change, rearrange, extend, or renew the
         time, rate, terms, or manner for payment or performance of any one or
         more of the Obligations (whether for principal, interest, fees,
         expenses, indemnifications, affirmative or negative covenants, or
         otherwise).

                                       3
<PAGE>   4

                  (iv) Compromise or settle any unpaid or unperformed Obligation
         or any other obligation or amount due or owing, or claimed to be due or
         owing, under any one or more of the Obligation Documents.

                  (v) Take, exchange, amend, eliminate, surrender, release, or
         subordinate any or all Security for any or all of the Obligations,
         accept additional or substituted Security therefor, and perfect or fail
         to perfect Lender's rights in any or all Security.

                  (vi) Discharge, release, substitute, or add Obligors.

                  (vii) Apply all monies received from Obligors or others, or
         from any Security for any of the Obligations, as Lender may determine
         to be in their best interest, without in any way being required to
         marshal Security or assets or to apply all or any part of such monies
         upon any particular Obligations.

         (b) No action or inaction of any Obligor or any other Person, and no
change of law or circumstances, shall release or diminish Guarantor's
obligations, liabilities, agreements, or duties hereunder, affect this Guaranty
in any way, or afford Guarantor any recourse against Lender. Without limiting
the foregoing, the obligations, liabilities, agreements, and duties of Guarantor
under this Guaranty shall not be released, diminished, impaired, reduced, or
affected by the occurrence of any or all of the following from time to time,
even if occurring without notice to or without the consent of Guarantor:

                  (i) Any voluntary or involuntary liquidation, dissolution,
         sale of all or substantially all assets, marshaling of assets or
         liabilities, receivership, conservatorship, assignment for the benefit
         of creditors, insolvency, bankruptcy, reorganization, arrangement, or
         composition of any Obligor or any other proceedings involving any
         Obligor or any of the assets of any Obligor under laws for the
         protection of debtors, or any discharge, impairment, modification,
         release, or limitation of the liability of, or stay of actions or lien
         enforcement proceedings against, any Obligor, any properties of any
         Obligor, or the estate in bankruptcy of any Obligor in the course of or
         resulting from any such proceedings.

                  (ii) The failure by Lender to file or enforce a claim in any
         proceeding described in the immediately preceding subsection (i) or to
         take any other action in any proceeding to which any Obligor is a
         party.

                  (iii) The release by operation of law of any Obligor from any
         of the Obligations or any other obligations to Lender.

                  (iv) The invalidity, deficiency, illegality, or
         unenforceability of any of the Obligations or the Obligation Documents,
         in whole or in part, any bar by any statute of limitations or other law
         of recovery on any of the Obligations, or any defense or excuse for
         failure to perform on account of force majeure, act of God, casualty,
         impossibility, impracticability, or other defense or excuse whatsoever.

                                       4
<PAGE>   5

                  (v) The failure of any Obligor or any other Person to sign any
         guaranty or other instrument or agreement within the contemplation of
         any Obligor, Lender.

                  (vi) The fact that Guarantor may have incurred directly part
         of the Obligations or is otherwise primarily liable therefor.

                  (vii) Without limiting any of the foregoing, any fact or event
         (whether or not similar to any of the foregoing) which in the absence
         of this provision would or might constitute or afford a legal or
         equitable discharge or release of or defense to a guarantor or surety
         other than the actual payment and performance by Guarantor under this
         Guaranty.

         (c) Lender may invoke the benefits of this Guaranty before pursuing any
remedies against any Obligor or any other Person and before proceeding against
any Security now or hereafter existing for the payment or performance of any of
the Obligations. Lender may maintain an action against Guarantor on this
Guaranty without joining any other Obligor therein and without bringing a
separate action against any other Obligor.

         (d) If any payment to Lender by any Obligor is held to constitute a
preference or a voidable transfer under applicable state or federal laws, or if
for any other reason Lender is required to refund such payment to the payor
thereof or to pay the amount thereof to any other Person, such payment to Lender
shall not constitute a release of Guarantor from any liability hereunder, and
Guarantor agrees to pay such amount to Lender on demand and agrees and
acknowledges that this Guaranty shall continue to be effective or shall be
reinstated, as the case may be, to the extent of any such payment or payments.
Any transfer by subrogation which is made as contemplated in Section 6 prior to
any such payment or payments shall (regardless of the terms of such transfer) be
automatically voided upon the making of any such payment or payments, and all
rights so transferred shall thereupon revert to and be vested in Lender.

         (e) This is a continuing guaranty and shall apply to and cover all
Obligations and renewals and extensions thereof and substitutions therefor from
time to time.

         Section 4. Waiver. Guarantor hereby waives, with respect to the
Obligations, this Guaranty, and the other Obligation Documents:

         (a) notice of the incurrence of any Obligation by Borrower, and notice
of any kind concerning the assets, liabilities, financial condition,
creditworthiness, businesses, prospects, or other affairs of Borrower (it being
understood and agreed that: (i) Guarantor shall take full responsibility for
informing itself of such matters, (ii) Lender shall not have any responsibility
of any kind to inform Guarantor of such matters, and (iii) Lender is hereby
authorized to assume that Guarantor, by virtue of its relationships with
Borrower which are independent of this Guaranty, has full and complete knowledge
of such matters whenever Lender extend credit to Borrower or take any other
action which may change or increase Guarantor's liabilities or losses
hereunder).

         (b) notice that Lender, any Obligor, or any other Person has taken or
omitted to take any action under any Obligation Document or any other agreement
or instrument relating thereto or relating to any Obligation.

                                       5
<PAGE>   6

         (c) notice of acceptance of this Guaranty and all rights of Guarantor
under Section 34.02 of the Texas Business and Commerce Code, as amended.

         (d) default, demand, presentment for payment, and notice of default,
demand, dishonor, nonpayment, or nonperformance.

         (e) notice of intention to accelerate, notice of acceleration, protest,
notice of protest, notice of any exercise of remedies (as described in the
following Section 5 or otherwise), and all other notices of any kind whatsoever.

         Section 5. Exercise of Remedies. Lender shall have the right to
enforce, from time to time, in any order and at Lender's sole discretion, any
rights, powers and remedies that Lender may have under the Obligation Documents
or otherwise, including judicial foreclosure, the exercise of rights of power of
sale, the taking of a deed or assignment in lieu of foreclosure, the appointment
of a receiver to collect rents, issues and profits, the exercise of remedies
against personal property, or the enforcement of any assignment of leases,
rentals, oil or gas production, or other properties or rights, whether real or
personal, tangible or intangible; and Guarantor shall be liable to Lender
hereunder for any deficiency resulting from the exercise by Lender of any such
right or remedy even though any rights which Guarantor may have against Borrower
or others may be destroyed or diminished by exercise of any such right or
remedy. No failure on the part of Lender to exercise, and no delay in
exercising, any right hereunder or under any other Obligation Document shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right preclude any other or further exercise thereof or the exercise of any
other right. The rights, powers and remedies of Lender provided herein and in
the other Obligation Documents are cumulative and are in addition to, and not
exclusive of, any other rights, powers or remedies provided by law or in equity.
The rights of Lender hereunder are not conditional or contingent on any attempt
by Lender to exercise any of its rights under any other Obligation Document
against any Obligor or any other Person.

         Section 6. Limited Subrogation.

         (a) Until all of the Obligations have been paid and performed in full
Guarantor shall have no right to exercise any right of subrogation,
reimbursement, indemnity, exoneration, contribution or any other claim which it
may now or hereafter have against or to any Obligor or any Security in
connection with this Guaranty (including any right of subrogation under Section
34.04 of the Texas Business and Commerce Code, as amended), and Guarantor hereby
waives any rights to enforce any remedy which Guarantor may have against
Borrower and any right to participate in any Security until such time. If any
amount shall be paid to Guarantor on account of any such subrogation or other
rights, any such other remedy, or any Security at any time when all of the
Obligations and all other expenses guaranteed pursuant hereto shall not have
been paid in full, such amount shall be held in trust for the benefit of Lender,
shall be segregated from the other funds of Guarantor and shall forthwith be
paid over to Lender to be held by Lender as collateral for, or then or at any
time thereafter applied in whole or in part by Lender against, all or any
portion of the Obligations, whether matured or unmatured, in such order as
Lender shall elect.

                                       6
<PAGE>   7

         (b) If Guarantor shall make payment to Lender of all or any portion of
the Obligations and if all of the Obligations shall be finally paid in full,
Lender will, at Guarantor's request and expense, execute and deliver to
Guarantor (without recourse, representation or warranty) appropriate documents
necessary to evidence the transfer by subrogation to Guarantor of an interest in
the Obligations resulting from such payment by Guarantor; provided that such
transfer shall be subject to Section 3(d) above and that without the consent of
Lender (which Lender may withhold in its discretion) Guarantor shall not have
the right to be subrogated to any claim or right against any Obligor which has
become owned by Lender, whose ownership has otherwise changed in the course of
enforcement of the Obligation Documents, or which Lender otherwise has released
or wishes to release from its Obligations.

         Section 7. Successors and Assigns. Guarantor's rights or obligations
hereunder may not be assigned or delegated, but this Guaranty and such
obligations shall pass to and be fully binding upon the successors of Guarantor,
as well as Guarantor. This Guaranty shall apply to and inure to the benefit of
Lender and their successors or assigns.

         Section 8. Subordination. Guarantor hereby subordinates and makes
inferior to the Obligations any and all indebtedness now or at any time
hereafter owed by Borrower to Guarantor. Guarantor agrees that after the
occurrence of any Default or Event of Default it will neither permit Borrower to
repay such indebtedness or any part thereof nor accept payment from Borrower of
such indebtedness or any part thereof without the prior written consent of
Lender. If Guarantor receives any such payment without the prior written consent
of Lender, the amount so paid shall be held in trust for the benefit of Lender,
shall be segregated from the other funds of Guarantor, and shall forthwith be
paid over to Lender to be held by Lender as collateral for, or then or at any
time thereafter applied in whole or in part by Lender against, all or any
portions of the Obligations, whether matured or unmatured, in such order as
Lender shall elect.

         Section 9. No Oral Change. No amendment of any provision of this
Guaranty shall be effective unless it is in writing and signed by Guarantor and
Lender, and no waiver of any provision of this Guaranty, and no consent to any
departure by Guarantor therefrom, shall be effective unless it is in writing and
signed by Lender, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given.

         Section 9. Invalidity of Particular Provisions. If any term or
provision of this Guaranty shall be determined to be illegal or unenforceable
all other terms and provisions hereof shall nevertheless remain effective and
shall be enforced to the fullest extent permitted by applicable law.

         Section 10. Term. This Guaranty shall be irrevocable until all of the
Obligations have been completely and finally paid and performed, no Lender has
any obligation to make any loans or other advances to Borrower, and all
obligations and undertakings of Borrower under, by reason of, or pursuant to the
Obligation Documents have been completely performed, and this Guaranty is
thereafter subject to reinstatement as provided in Section 3(d). All extensions
of credit and financial accommodations heretofore or hereafter made by Lender to
Borrower shall be conclusively presumed to have been made in acceptance hereof
and in reliance hereon.

                                       7
<PAGE>   8

         In the event of the death of Guarantor, the obligation of the deceased
shall continue in full force and effect against his estate as to all Obligations
that shall have been created or incurred by Borrower prior to the time when
Lender shall have received notice, in writing, of such death.

         Section 11. Notices. Any notice or communication required or permitted
hereunder shall be given in writing, sent by personal delivery, by telecopy, by

the parties hereto further agrees that it will cooperate with the other after
the consummation of the Transactions for the purpose of providing Purchaser with
the information and access to information necessary to ensure Purchaser with a
reasonably smooth transition into the ownership of the Business.

         5.3 CONSENTS. To the extent that the assignment by Seller of any
Scheduled Contract or Permit to be assigned hereunder shall require the consent
or approval of another party thereto, the consummation of the Transactions shall
not constitute an assignment or attempt at an assignment thereof if such

third party consent with respect to any one or more Scheduled Contract or Permit
is not obtained at or prior to Closing, each party hereto agrees to take
whatever action may be necessary to provide Purchaser with the uninhibited
benefits of such Scheduled Contracts and Permits, subject to the assumption by
the Purchaser of Seller's obligations thereunder.

         5.4 AGREEMENT REGARDING BROKERS. Each party agrees that it will pay or

any or all of the employees and independent contractors of Seller for their
continued employment with Purchaser from and after the Closing Date at
compensation levels as Purchaser and such employees or contractors shall agree.
Purchaser shall have no liability whatsoever with respect to any matter relating
to the employment or contracting of such persons by Seller prior to the Closing
Date.

         5.8 NONCOMPETITION.

                  (a) During the period commencing with the Closing Date and
         ending on the second anniversary thereof, Seller and its Affiliates
         shall not, as a partner, trustee, director, officer, employee,
         shareholder, option holder, lender of money, guarantor or consultant,
         be engaged, directly or indirectly, in any business that is in the
         Business within any state in which the Business is currently conducted.
         In addition, until the second anniversary of the Closing Date, Seller
         and its Affiliates shall not, directly or indirectly, divert or attempt
         to divert from the Purchaser any business whatsoever by influencing or
         attempting to influence any Person which is a customer of Seller
         immediately prior to the Closing or from whom Seller are soliciting
         business, immediately prior to the Closing. The provisions of this
         Section 5.8(a) shall apply throughout the United States and its
         territories. Notwithstanding the preceding sentence, however, in the
         event that any court of competent jurisdiction shall determine that the
         scope of this Section 5.8(a) is overly broad or unenforceable in any
         way, it is the intent of the parties that such provisions be reformed
         such that the scope of the otherwise unenforceable provision is as
         great as may be permissible under applicable law.

                  (b) Until the second anniversary of the Closing, Seller
         covenants and agrees not to, directly or indirectly, solicit, take
         away, hire, employ or endeavor to employ any person who is an employee
         of Purchaser or any Affiliate of Purchaser or, directly or indirectly,
         divert or attempt to divert from Purchaser or any Affiliate of
         Purchaser any business whatsoever by influencing or attempting to
         influence any person or business entity which is a customer of, or has
         a similar business relationship with, Purchaser or any Affiliate of
         Purchaser or from which Purchaser or any Affiliate of Purchaser is
         soliciting business.

                  (c) Seller recognizes that the restrictions set forth in this
         Section 5.8 are required for the reasonable protection of Purchaser and
         its investment in the Business, and as such, each of Seller expressly
         acknowledges that such restrictions are fair and reasonable for that
         purpose and that money damages alone will be an inadequate remedy for
         any breach or violation of the provisions of this Section 5.8. In
         addition, Seller agrees that in addition to all of the remedies
         provided for in this Agreement for breaches thereof, Purchaser shall be
         entitled, as a matter of right, to injunctive relief, including
         specific performance, with respect to any breach or violation of the
         provisions of this Section 5.8.

7.       SURVIVAL AND INDEMNIFICATION

         7.1 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations and
warranties of Seller shall survive the Closing and any investigation on the part
of the parties hereto and shall continue in full force and effect for a period
of two (2) years after the Closing Date; provided, however, that (i) the
representations and warranties in Section 3.9 shall survive until the expiration
of the statutory period of limitations for assessment of

ASSET PURCHASE AGREEMENT - PAGE 11
<PAGE>   15

taxable year of Seller which begins before the Closing Date, and (ii) the
representations and warranties in Sections 3.19 shall survive indefinitely. The
covenants and agreements of the parties set forth in this Agreement shall not be
affected by the expiration of any representation or warranty pursuant to this
Section 7.1 and shall survive indefinitely.

         7.2 INDEMNITY.

                  (a) Seller agrees to indemnify and hold Purchaser, its
         officers, directors, agents, attorneys and accountants ("Purchaser
         Indemnitees") harmless from any and all damages, losses (which shall
         include any diminution in value, liabilities, joint or several),
         payments, obligations, penalties, claims, litigation, demands,
         defenses, judgments, suits, proceedings, costs, disbursements or
         expenses (including without limitation, fees, disbursements and
         expenses of attorneys, accountants and other professional advisors and
         of expert witnesses and costs of investigation and preparation) of any
         kind or nature whatsoever (collectively "Damages"), directly or
         indirectly resulting from, relating to or arising out of:

                           (i) any breach or nonperformance (partial or total)
                  of or inaccuracy in any representation or warranty or covenant
                  or agreement of Seller contained in any Operative Document
                  which survives the Closing hereof;

                           (ii) any liability or obligation arising out of
                  Seller's business as conducted prior to the Closing and not
                  expressly assumed by Purchaser pursuant to this Agreement;

                           (iii) any losses or costs of defending against any
                  claims which may be made against Purchaser by any Person
                  claiming violations by Seller of any local, state, or federal
                  law relating to the employment relationship, including, but
                  not limited to, wages, hours, concerted activity,
                  nondiscrimination, occupational health and safety and the
                  payment and withholding of Taxes, where such claims arise out
                  of circumstances occurring prior to the Closing Date;

                           (iv) any actual or threatened violation of or
                  non-compliance with, or remedial obligation arising under, any
                  environmental laws arising from any event, condition,
                  circumstance, activity, practice, incident, action or plan
                  existing or occurring prior to the Closing relating in any way
                  to the assets or the business of Seller;

                           (v) Seller's failure to comply with the laws of any
                  jurisdiction with respect to the bulk sales laws that may be
                  applicable to the sale of the Assets to Purchaser as
                  contemplated hereby; and

                           (vi) the Transaction Expenses incurred by Seller.

                  (b) Seller shall retain liability, and shall indemnify
         Purchaser, for the payment of any Tax liabilities of Seller.

         7.3 NO THIRD PARTY BENEFICIARIES. The foregoing indemnification is
given solely for the purpose of protecting the Purchaser Indemnitees and shall
not be deemed extended to, or interpreted in a manner to confer any benefit,
right or cause of action upon, any other Person.

         7.4 INDEMNIFICATION NOTICE. If a Purchaser Indemnitee intends to
exercise its right to indemnification provided in this Article 7, such Purchaser
Indemnitee shall provide the party or parties from whom the indemnification will
be sought (the "Indemnitor") at least fifteen (15) days prior written notice
(the

ASSET PURCHASE AGREEMENT - PAGE 12
<PAGE>   16

"Indemnification Notice") of such Purchaser Indemnitee's intention to do so
and the facts or circumstances giving rise to the claim ("Indemnification
Claim"). Nothing contained herein shall preclude any Purchaser Indemnitee from
taking any actions deemed reasonably necessary or appropriate in response to any
third party claims during such interim period. An Indemnification Claim may, at
the option of the Purchaser Indemnitee, be asserted as soon as any situation,
event or occurrence has been noticed by the Purchaser Indemnitee regardless
whether actual harm has been suffered or out-of-pocket expenses incurred. During
such fifteen (15) day period, the Indemnitor shall be entitled to cure the
defect or situation giving rise to the Indemnification Claim to the satisfaction
of the Purchaser Indemnitee. If the Indemnitor is unwilling or unable to cure
the defect giving rise to the Indemnification Claim during such fifteen (15)
period, the Purchaser Indemnitee may, on the sixteenth (16th) day after the
Indemnification Notice, seek indemnification as provided in this Article 7.

         7.5 OFFSET. At any time or from time to time prior to the final payment
by Purchaser to Seller of any amounts or sums due under or pursuant to this
Agreement, the Promissory Note or any other Operative Document, Purchaser shall
be entitled, in addition to, and not in lieu of, any other right or remedy which
Purchaser may have against Seller, under or pursuant to this Agreement, or
otherwise, to notify Seller in writing (an "Offset Notice") that Purchaser
reasonably believes that it is entitled to indemnity for Damages under Section
7.2. Any Offset Notice provided hereunder shall identify the provision of this
Agreement which Purchaser believes entitles it to such indemnity for Damages and
shall briefly identify the facts which constitute the basis for each such claim
of indemnity and the dollar amount of such claim. If on or before thirty (30)
days after delivery of the Offset Notice, Seller shall not have objected
thereto, Purchaser may, but, shall not be required to, offset against any
portion of the amounts due under the Promissory Note then remaining unpaid, the
amount of the Damages claimed in the Offset Notice (and thus to reduce the
amounts due under this Agreement). Notwithstanding any offset exercised pursuant
to this Section 7.5, to the extent that the actual amount of any Damages arising
from a claim for indemnity set forth in an Offset Notice shall exceed the value
of the offset against the amounts due under this Agreement claimed, Seller shall
remain liable for, and shall promptly reimburse Purchaser the amount of, any
such excess Damages. If on or before thirty days following delivery of the
Offset Notice, Seller shall notify Purchaser that Seller questions the amount of
any Damages for which indemnity is claimed therein (or the entitlement to
indemnity), Purchaser shall nonetheless be entitled to exercise its rights of
offset provided for in this Section 7.5, but in lieu of reducing the amounts due
under this Agreement immediately, shall defer payment of a portion or portions
of the amounts due under the Promissory Note remaining unpaid in the amount of
the disputed claim until such time as (i) Purchaser shall have received written
authorization from Seller to retain such unpaid portion of the amounts due under
the Promissory Note in partial or total satisfaction of Purchaser's claim for
indemnity, or (ii) Seller shall have delivered to Purchaser, a certified or
file-stamped copy of a final decision of a court of competent jurisdiction
establishing the amount of such Damages or directing a specific distribution of
all or any part of the amounts due under the Promissory Note being held by
Purchaser pursuant to this Section 7.5. It shall be a condition to Purchaser's
obligation to defer applying any unpaid portion of the amounts due under the
Promissory Note, subject to the resolution of Seller's objection to the amount
of Damages claimed or the entitlement to indemnity with regard thereto, that
Seller specify in writing the provisions of this Agreement and other facts
supporting such objection. Purchaser shall not be obligated to exercise the
rights of offset provided for in this Section 7.5, and no failure to exercise
any such right of offset shall relieve Seller of any indemnity obligations under
Section 7.2, or otherwise.

8.       GENERAL PROVISIONS AND OTHER AGREEMENTS

         8.1 NOTICES. All notices and other communications hereunder shall be in
