Contract Obligations, Buyer is not assuming, accepting or undertaking any
debt, obligation, duty or liability of Seller of any kind whatsoever,
accrued, contingent or otherwise, whether arising out of, or related to, the
operation, use or ownership of the Purchased Assets, the manufacture or sale

such lease and agreement is in good standing and is valid and binding in
accordance with its terms. Seller and each lessor have in all material

agreement. None of the rights of Seller in such property under any such lease

basis (but without footnotes), except as noted therein. None of the Financial
Statements include or omit an asset or a liability or obligation of any kind or
nature (whether known or unknown and whether absolute, accrued, contingent or
other), the inclusion or omission of which would render such Financial
Statements materially misleading. Seller has no liabilities (of any kind or
nature, whether known or unknown and whether absolute, accrued, contingent or
other) that are not adequately reflected or reserved against on the face of the
Financial Statements except liabilities incurred since such date in the ordinary
course of business and consistent with past practice. Since June 30, 2000, other

material adverse change in the Business, condition (financial or otherwise),
operations, or prospects of Seller; (b) any damage, destruction, or loss,

Business, condition (financial or otherwise), operations, or prospects of
Seller; (c) any entry into or termination of any material commitment, contract,

breach by Seller in any material respect under any Seller Contract, or
license or permit related thereto or required in the performance thereof.

Seller may distribute the Securities to its members. Seller acknowledges that
the issuance of the Securities has not been registered with the SEC under the

severally, agree to indemnify, defend and hold Buyer and its Affiliates
harmless from and against any and all losses, liabilities, claims, demands,

sustained by Buyer or any of its Affiliates caused by (i) the breach of any
representation or warranty of Seller or Owners contained in this Agreement or
in any certificate, agreement, document or instrument delivered pursuant to
this Agreement, (ii) the breach of any covenant or agreement, of Seller
contained in this Agreement or in any certificate, agreement, document or
instrument delivered pursuant to this Agreement, or (iii) any Claim relating

Business to or on the Closing Date unless and to the extent that such Claim
arises solely from any action of Buyer after the Closing or is expressly
assumed by Buyer hereunder, except, that Seller and Owners shall have no
liability pursuant to SECTION 12.06(a)(i) for the first $15,000 of aggregate
Claims (the "Buyer Basket").

                  (b)   BY BUYER. Buyer agrees to indemnify, defend and hold
Seller harmless from and against any and all Claims sustained by Seller caused

Party") shall as promptly as practicable notify the party from which such
indemnification is sought (the "Indemnifying Party") upon which the
Indemnified Party intends to base a claim for indemnification or reimbursement
hereunder; provided, however, that the failure of an Indemnified Party to so
notify the Indemnifying Party shall not relieve the Indemnifying Party from
any liability under this Agreement to the Indemnified Party with respect to
such Claim except to the extent the Indemnifying Party is actually prejudiced

give rise to the indemnity or reimbursement obligation of the Indemnifying
Party hereunder, and may assert any defense of any party; provided, however,
that the Indemnified Party shall have the right at its own expense to
participate jointly with the Indemnifying Party in the defense of any claim,
demand, lawsuit or other Proceeding in connection with which the Indemnified
Party claims indemnification or reimbursement hereunder. Notwithstanding the
right of an Indemnified Party so to participate, the Indemnifying Party shall
have the sole right to settle or otherwise dispose of such claim, demand,
lawsuit or other Proceeding on such terms as the Indemnifying Party, in its
sole discretion, shall deem appropriate with respect to any issue involved in
such claim, demand, lawsuit or other Proceeding as to which (i) the
Indemnifying Party shall have acknowledged the obligation to indemnify the
Indemnified Party hereunder and the settlement is solely for cash or (ii) the
Indemnified Party shall have declined so to participate and, in either case,
the Indemnified Party is provided a full and complete release of Claims.

                  (d)   SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties of the parties to this Agreement shall survive
the Closing Date and shall remain in full force and effect for a period of two
years following the Closing Date; provided, that the representations and
warranties related to Tax matters shall survive until the applicable statute
of limitations for any potential Tax liability has expired and representations
and warranties related to environmental claims shall survive indefinitely (the
period during which the representations and warranties shall survive being
referred to herein with respect to such representations and warranties as the
"Survival Period"), and shall be effective with respect to any inaccuracy
therein or breach thereof (and a claim for indemnification under SECTION 12.06
hereof may be made thereon) if a written notice asserting the claim shall have
been duly given in accordance with ARTICLE XII hereof within the Survival
Period with respect to such matter. Any claim for indemnification made during
the Survival Period shall be valid and the representations and warranties
relating thereto shall remain in effect for purposes of such indemnification
notwithstanding that such claim may not be resolved within the Survival
Period. All representations, warranties and covenants and agreements made by
the parties shall not be affected by any investigation heretofore or hereafter
made by and on behalf of any of them and shall not be deemed merged into any
instruments or agreements delivered in connection with this Agreement or
otherwise in connection with the transactions contemplated hereby.

                  (e)   EXCLUSIVE RIGHTS AND REMEDIES. The rights and remedies
provided in this SECTION 12.06 shall be the exclusive rights and remedies,
contractual or otherwise, of the indemnified Persons with respect to breaches
of the representations, warranties, covenants and agreements contained in this
Agreement.

         12.07    ACTIONS OF THE PARTIES AFTER THE CLOSING DATE. The Parties
agree that after the Closing, they will take the actions described in this
SECTION 12.07.

<PAGE>

                  (a)   Seller acknowledges and agrees that from and after the
Closing, Buyer will be entitled to originals of all title documents and copies
of all other documents, books, records (including tax records), agreements,
and financial data of any sort relating to the Business and the Purchased
Assets.

                  (b)   In the event and for so long as any party actively is
contesting or defending against any action, suit, proceeding, hearing,
investigation, charge, complaint, claim, or demand in connection with (i) any
transaction contemplated under this Agreement or (ii) any fact, situation,
circumstance, status, condition, activity, practice, plan, occurrence, event,
incident, action, failure to act, or transaction on or prior to the Closing
Date involving the Business or the Purchased Assets, the other party will to
the extent reasonably practicable cooperate with the contesting or defending
party and its counsel in the contest or defense, make available its personnel,
and provide such testimony and access to its books and records as shall be
necessary in connection with the contest or defense, all at the sole cost and
expense of the contesting or defending party. However, with respect to any
such information as to which the contesting or defending party may reasonably
assert that the disclosure pursuant hereto would waive a privilege, the
parties will use their reasonable efforts to develop procedures to maintain
such privilege.

                  (c)   Seller will not take any action that is designed or
intended to have the effect of discouraging any lessor, licensor, customer,
supplier, or other business associate of the Business from maintaining the
same business relationships with Buyer after the Closing Date as it maintained
with Seller prior to the Closing Date. Seller will refer all customer
inquiries relating to the Business to Buyer from and after the Closing Date.

                  (d)   If, after the Closing Date, any consent necessary to
convey, transfer and assign the Seller Contracts has not been obtained, Seller
shall use its best efforts to afford Buyer the benefits under each such
Contract and Seller's protection from the obligations under each such
Contract, to the extent such Seller may do so without breaching or violating
the terms of any such Contract.

                  (e)   If, after the Closing Date, Seller obtains consent to
assign, convey and transfer any of the Seller Contracts, then any agreement
which Seller and Buyer have theretofore entered into or agreed upon in
respect of such Contract shall be terminated with respect to such Contract
effective as of the date Seller notifies Buyer of such consent; provided, in
no event shall such termination relieve any of the parties of its obligations
under such agreement attributable to periods prior to such termination.

                  (f)   It is the Parties' intent that all of the Purchased
Assets be conveyed to Buyer at the Closing. Accordingly, if either party
determines that less than all of the Purchased Assets have been conveyed
(whether due to the failure to identify all of the Purchased Assets at
Closing, the failure to obtain all required consents to assignment or
otherwise), such Party shall promptly notify the other of such fact and the
Parties will take all appropriate action and execute any additional documents,
instruments or conveyances of any kind which may be reasonably necessary to
carry out the foregoing intent.

                                    -27-

                  (g)   Seller agrees that after the Closing Date any facts,
information, know-how, processes, trade secrets, customer lists or
confidential matters that relate in any way to the Purchased Assets shall be
maintained in confidence and shall not be divulged by Seller to any party
unless and until they shall become public knowledge (other than by disclosure
by Seller or its managers, employees or agents) or as required by law. Seller
further agrees to use its best efforts to ensure that none of its respective
managers, employees or agents (so long as they are employed by Seller) divulge
any such confidential information to a third party or use the same for the
benefit of Seller, any such officer, employee or agent or any other third
party, unless and until it shall have become public knowledge (other than by
disclosure by Seller or its officers, employees or agents). Buyer shall have
the right to interview Seller's employees for the purpose of obtaining
information concerning the Business and Seller hereby waives any right, claim,
or cause of action, express or implied, which Seller may have against any of
Seller's managers, employees or agents by reason of any such manager, employee
or agent divulging to Buyer after the Closing Date any facts, information,
know-how, processes, trade secrets, customer lists or similar confidential
matters that relate to the Business or the Purchased Assets.

         12.08    NONASSIGNABLE CONTRACTS OR AUTHORIZATIONS. To the extent
that assignment hereunder by the Seller to Buyer of any Seller Contract is not
permitted or is not permitted without the consent of any third party, this
Agreement will not be deemed to constitute an undertaking to assign the same
if such consent is not given or if such an undertaking otherwise would
constitute a breach of or cause a loss of benefits thereunder. After the
Closing, Seller will use commercially reasonable efforts to obtain any and all
such third party consents which Buyer may request. If any such third party
consent is not obtained, , the Seller will cooperate with Buyer, in any
reasonable arrangement designed to provide to Buyer after the Closing the
benefits under the applicable Seller Contract.

                                  ARTICLE XIII
                                  MISCELLANEOUS

         13.01    EXPENSES. Except as otherwise provided herein, each Party
will pay its own costs and expenses incurred in connection with this Agreement
and the transactions contemplated hereby. In addition, Seller agrees that the
portion of the Purchase Price allocable to those items of the Purchased Assets
subject to Transfer Taxes (as defined below) in connection with the
consummation of the transactions contemplated hereby includes all applicable
state and local sales, use, transfer, retailer occupation and other similar
Taxes ("Transfer Taxes")due with respect to the transfer of such Purchased
Assets.

         13.02    NOTICES. All notices and other communications hereunder
shall be in writing and shall be deemed to have been given if delivered

               MEMBERSHIP INTEREST PURCHASE, SALE AND REDEMPTION

         2.01 THE SALES TRANSACTION. (a) At the Effective Time of the Sales
Transaction, in accordance with the terms of this Agreement, Sellers shall sell
to Buyer, and Buyer shall purchase from Sellers the number of shares of
membership interests in the Company set forth opposite each Seller's name in
Schedule 2.01 attached hereto, and Buyer will make payment to Sellers
collectively in the amounts indicated in Section 2.01(b) below. The consummation
of the Transaction together with the delivery of the various membership interest
certificates, assignments, conveyances, officer certificates, agreements,
assumptions, opinions and other documents required or contemplated by this
Agreement (the "Sales Transaction Documents") is herein called the "Closing."

         (b) The Purchase Price shall consist of the following:

                  (i)      Buyer shall pay the sum of $600,000 less the
         aggregate amount of liabilities of the Company at the Effective Time of
         the Sales Transaction (offset by the amount of any prepaid expenses of
         the Company on such date) payable to the joint order of the Sellers at
         Closing by delivery of a check;

                  (ii)     Buyer shall pay Sellers five percent of the gross
         revenues invoiced and actually collected by Buyer for environmental
         consulting and remediation services rendered in the State of Kentucky
         (the "Revenue Percentage") during the period of five years following
         the date of Closing. Such Revenue Percentage shall not apply to
         discounts granted to Buyer's customers in the normal course of
         business, disallowances by any state agency responsible for
         reimbursement of charges for work invoiced to such agency, revenues
         received or to be received that are in dispute (until such dispute is
         resolved and revenues are actually received by Buyer), and revenues
         deemed by Buyer in its sole discretion to be non-collectable revenues.
         Revenues collected from engineering and other services not related to
         environmental consulting and remediation and all other revenues
         collected by Buyer outside the State of Kentucky shall not be included
         in the calculation or payment of the Revenue Percentage. The Revenue
         Percentage shall be payable by the Buyer by check to the joint order of
         the Sellers within thirty (30) days after the end of the calendar month
         in which the Buyer receives payment for said services giving rise to
         said payment obligation hereunder.

         2.02 EFFECTIVE TIME OF THE SALES TRANSACTION. The effective date of
Sales Transaction is the Closing Date, and the Sales Transaction shall become
effective, subject to the terms and conditions of this Agreement, when the
actions and deliveries set forth in Articles VII, VIII and VIV below shall have
in all respects been completed. The date and time when the Sales Transaction
shall become effective as aforesaid is herein referred to as the "Effective Time
of the Sales Transaction" and all items of income, gain, loss and distributions
of the Company allocable with respect to the membership interests being conveyed
to Buyer hereunder shall be allocated as of said date.

         2.03 REDEMPTION OF REMAINING MEMBERSHIP INTERESTS. Immediately after
the transfer of the membership interests in the Company pursuant to Section
2.01, the Sellers shall surrender

                                   -iv-
<PAGE>

and transfer to the Company for redemption, all of the remaining shares of
membership interests owned by Sellers, so that after said surrender and
redemption, the Buyer shall be the sole member of the Company owning all of
the outstanding membership interests in the Company. In exchange for the
shares of membership interests in the Company surrendered and redeemed under
this Section 2.03, the Company shall distribute, assign, pay, convey and
transfer to the Sellers the Excluded Assets listed on EXHIBIT A attached
hereto and the Sellers shall thereby indemnify and hold Buyer harmless from
any and all loss, cost, expense, liabilities, obligations, charges and
commitments attributable to the Excluded Assets regardless of whether the
same accrue or are incurred before or after the Effective Time of the Sales
Transaction.

                                   ARTICLE III
                    REPRESENTATIONS AND WARRANTIES OF SELLERS

liability company duly organized, validly existing and in good standing under
Kentucky law and has the requisite power and authority to carry on its business
as it is now being conducted. The Company is duly qualified as a foreign limited
liability company to do business, and is in good standing, in each jurisdiction
where the character of the properties owned or leased by it, or the nature of
its activities, is such that qualification as a foreign limited liability
company in that jurisdiction is required by law except for those jurisdictions
in which the failure to be so qualified would not, in the aggregate, have a
material adverse effect on the Business of the Company.

         3.02 CAPITALIZATION. All of the shares of membership interests of the
Company that are outstanding as of the date hereof, or will be outstanding
immediately prior to the Effective Time of the Sales Transaction, are or will be
duly authorized, validly issued, fully paid and nonassessable, are not or will
not be subject to, or issued in violation of, any preemptive rights. Except as
set forth above, there are no other membership interests authorized or
outstanding, and there are no other agreements, claims or commitments of any
nature whatsoever (whether firm or conditional) obligating the Company to issue,
transfer, deliver to sell, or cause to be issued, transferred, delivered or
sold, additional membership interests or other interests of the Company or
obligating the Company to grant, extend or enter into any such agreement or
commitment.

         3.03 SUBSIDIARIES. The Company does not own, directly or indirectly,
any shares of stock or any other equity or long-term debt securities of any
corporation or have any material equity interest in any firm, partnership, joint
venture, association or other entity.

         3.04 AUTHORIZATION OF AGREEMENT. (a) Sellers have all requisite power
and authority to enter into and perform all of their obligations under this
Agreement. The execution and delivery of this Agreement by Sellers and the
consummation by Sellers of the transactions contemplated hereby have been duly

<PAGE>

enforceability may be subject to (i) any applicable bankruptcy, insolvency,
reorganization or other law relating to or affecting creditors' rights
generally and (ii) general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

         (b) Neither the execution and delivery of this Agreement by Sellers nor
the consummation of the Transactions and the other transactions contemplated
hereby to be performed by Sellers will (i) violate or conflict with any
provision of the Articles of Organization or the Operating Agreement of the

of any law, rule, regulation, order, permit, certificate, writ, judgment,
injunction, decree, determination, award or other decision of any Governmental
Entity, other regulatory or self-regulatory body or association or arbitrator
binding upon the Company or the Business, except where such violations or
conflicts would not in the aggregate have a material adverse effect on the
Business, properties, financial condition or results of operations of the
Company or on the ability of Sellers to consummate the transactions contemplated
hereby, and except for violations that will be cured, waived or terminated prior
to the Effective Time of the Sales Transaction.

         (c) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby to be performed by Sellers
will result in a breach of or constitute a default (or with notice or lapse of
time or both result in a breach of or constitute a default) under, or give rise
to a right of termination, cancellation, acceleration or repurchase of any
obligation or a right of first refusal with respect to any material property or
asset or a loss of a material benefit or the imposition of a material penalty
under, any of the terms, conditions or provisions of:

                  (i)      any mortgage, indenture, loan, or credit agreement or

         borrowed to which any of Sellers or the Company is a party or by which
         it or any of its properties is bound or affected, or pursuant to which
         any of Sellers or the Company has guaranteed the indebtedness or
         preferred stock of any person or entity, or

                  (ii)     any contract, lease, license, tariff, or other
         agreement or instrument to which the Company is a party or by which it
         or any of its properties is bound or affected.

deed of trust, pledge, lien, security interest or other charge or encumbrance of
any nature upon or with respect to any of the properties or other assets now or
hereafter owned by the Company except where such would not in the aggregate have
a material adverse effect on the Business, properties, financial condition or
results of operations of the Company or on the ability of the Company to
consummate the transactions contemplated hereby.

                                   -vi-
<PAGE>

         (e) No consent, approval, order, certificate or authorization of, or
registration, declaration or filing with, any Governmental Entity is required by
or with respect to Sellers or the Company in connection with the execution and
delivery of this Agreement by Sellers or the consummation by Sellers of the
transactions contemplated hereby, other than such filings or registrations that,
if not made, and such authorizations, consents or approvals, that, if not
received, would not in the aggregate have a material adverse effect on the
Business, properties, financial condition or results of operations of the
Company or on the ability of Sellers to consummate the transactions contemplated
hereby.

         (f) The Company has made or obtained each registration, filing,
submission, license, permit, certificate, determination or governmental approval
necessary to enable it to carry on the Business. All such registrations, filings
and submissions with any Governmental Entity relating to the operations of the
Company were in material compliance with applicable law when filed, and no
material deficiencies have been asserted by any such authority with respect to
such registrations, filing or submissions.

         3.05 CONTRACTS AND AGREEMENTS. (a) Before the Closing, Sellers will, or
will cause the Company to, provide Buyer access to and the right to copy all
contracts, agreements, commitments and instruments, including any and all
amendments thereto involving a commitment or obligation on to the party or
parties to the contracts, agreements, commitments and instruments of $5,000 or

is a party or by which the Company or any of its assets are bound, including,
but not limited to, purchase orders and agreements, maintenance agreements, bulk

Contracts.

         (b) The Company has complied in all material respects with the
provisions of all the Material Contracts; the Company is not in material breach
or default under, and there is no valid basis for any claim of breach or default
under, and there has been no waiver of any breach or default under, any term or
provision of any Material Contract; all the Material Contracts are in full force
and effect and constitute legal, valid and binding obligations of the respective
parties thereto in accordance with their terms. There has been no amendment or
modification of any of the Material Contracts, except such amendments that have
been delivered to Buyer. The Company is not participating in any discussions or
negotiations regarding modification of any of the Material Contracts. The
Material Contracts may be assigned to Buyer pursuant to this Agreement and the
enforceability of any of the Material Contracts will not be impaired by the
consummation of the transactions contemplated in this Agreement.

         3.06 TRADE NAMES, TRADEMARKS, COPYRIGHTS, ETC. The Company has not
conducted any part of the Business or utilized any of its assets preceding the
date of this Agreement under a trade name, fictitious name or other similar name
other than Kentucky Environmental Network, LLC or Kentucky Environmental
Network, Inc. There have not been asserted against the

                                   -vii-
<PAGE>

Company any claims that any product, activity or operation of the Company
infringes upon or involves, or had resulted in the infringement of, any
proprietary right of any other person, corporation or other entity; and no
proceedings have been instituted, are pending or are threatened which
challenge the rights of the Company with respect thereto, in each case, which
would have a material adverse effect on the business, properties, financial
condition or results of operations of the Company.

         3.07 PROPRIETARY RIGHTS. The Company possesses full ownership of, or
adequate and enforceable long-term licenses or other rights to use (without
payment), all Proprietary Rights owned by or registered in the name of and of
the Company or used in the Business without any known conflict with the rights
of others. The Company has in all material respects performed all of the
obligations required to be performed by it, and is not in default in any
material respect, under any agreement relating to any Proprietary Right.
Proprietary Rights constitute trade secrets of the Company within the meaning of
all applicable laws, and, to Sellers' knowledge, the Company has taken all
reasonable necessary steps required by law to protect these trade secrets as
such. The Company owns or has valid rights to use all Proprietary Rights. No
person has made or, to Sellers' knowledge, threatened to make any claims that
the operation of the Business is in violation of or infringes any Proprietary
Rights or any other proprietary or trade rights of any third person. To Sellers'
knowledge, no third person is in violation of or is infringing upon any
Proprietary Rights. The Proprietary Rights include all of such rights and
interests which are reasonably necessary for the conduct of the Business as it
is currently being conducted.

         3.08 TITLE TO PROPERTIES: ABSENCE OF LIENS AND ENCUMBRANCES: LEASES.
(a) The Company has good and marketable title to the material assets (other than
Excluded Assets), tangible and intangible, free and clear of all mortgages,
liens, pledges, charges and encumbrances of any nature whatsoever except for
those liabilities which are recorded on the Financial Statements as such and
except for Permitted Encumbrances.

         (b) Except for the lease arrangement for the real property to be
replaced by the lease described in Section 9.04, the Company has not entered
into any leases or agreements under which the Company is lessee of, or holds or
operates, any property owned by any third party and which are to be assumed by
Buyer, including in each case, the expiration date of such lease or agreement,
the payments to be made thereunder, the details of any option to renew or to
purchase thereunder, the name or names of the lessor of each such lease and a
brief description of the property covered thereby. Each such lease and agreement
is in good standing and is valid and binding in accordance with its terms. The
Company and each lessor have in all material respects performed all the
obligations required to be performed by them to date and are not in default in
any material respect under any such lease or agreement. None of the rights of
the Company in such property under any such lease or agreement is subject to
termination as the result of the transactions contemplated by this Agreement.

         (c) Except as disclosed in SCHEDULE 3.08, the material items of
tangible personal property of the Company are in good operating condition and
repair, subject to ordinary wear and tear. The Company is not in violation of
any applicable regulation, ordinance or other similar law,

                                  -viii-
<PAGE>

order, regulation or requirement relating to the Business or properties
(including the placement, installation, operation, configuration, design or
maintenance of emissions from such properties) which, if enforced, would
materially and adversely affect the Business, properties, financial condition
or results of operations.

         3.09 FINANCIAL STATEMENTS; NO ADVERSE CHANGES. Sellers or the Company
have delivered to Buyer copies of the Company's unaudited balance sheet as at
December 31, 1999, and income statements for the year ended December 31, 1999,
and its balances sheet as at June 30, 2000 and income statements for the six
months ended June 30, 2000 (the "Financial Statements") copies of which are
attached hereto as EXHIBIT B. The Financial Statements are complete in all
material respects, present fairly the financial condition of the Company at the
dates indicated, and the results of operations for the respective periods
indicated, and, except to the extent described in SCHEDULE 3.09 or in such
Financial Statements, have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis. None of the Financial
Statements includes or omits an asset or a liability or obligation of any kind
or nature (whether known or unknown and whether absolute, accrued, contingent or
other), the inclusion or omission of which would render such Financial
Statements materially misleading. The Company has no liabilities (of any kind or
nature, whether known or unknown and whether absolute, accrued, contingent or
other) that are not adequately reflected or reserved against on the face of the
Financial Statements except liabilities incurred since such date in the ordinary
course of business and consistent with past practice. Without limiting the
foregoing, (a) there are no unpaid leasehold improvements at any of the
Company's facilities or locations for which the Company is or will be
responsible and (b) there are no deferred rents due to lessors at or with
respect to any of such facilities or locations. Since June 30, 2000, other than
as contemplated or caused by this Agreement, there has not been (a) any material
adverse change in the business, condition (financial or otherwise), operations,
or prospects of the Company; (b) any damage, destruction, or loss, whether
covered by insurance or not, having a material adverse effect on the Business,
condition (financial or otherwise), operations, or prospects of the Company; (c)
any entry into or termination of any material commitment, contract, agreement,
or transaction (including, without limitation, any material borrowing or capital
expenditure or sale or other disposition of any material asset or assets) of or
involving the Company other than this Agreement and agreements executed in the
ordinary course of business; (d) any redemption, repurchase, or other
acquisition for value of Units by the Company, or any issuance of Units of the
Company or of securities convertible into or rights to acquire any such Units or
any dividend or distribution declared, set aside, or paid on the Units; (e) any
transfer of or right granted under any material lease, license, agreement,
patent, trademark, trade name, or copyright of the Company; (f) any sale or
other disposition of any asset of any of the Company, or any mortgage, pledge,
or imposition of any lien or other encumbrance on any asset of the Company,
other than in the ordinary course of business, or any agreement relating to any
of the foregoing; or (g) any default or breach by the Company in any material
respect under any contract, license or permit. Since June 30, 2000, the Company
has conducted the Business only in the ordinary and usual course, and, without
limiting the foregoing, no changes have been made in (a) executive compensation
levels; (b) the manner in which other employees of the Company are compensated;
(c) supplemental benefits provided to any such executives or other employees;
(d) inventory levels in relation to sales levels, except, in any such

                                   -ix-

<PAGE>

case, in the ordinary course of business and, in any event, without material
adverse effect on the Business, condition (financial or otherwise),
operations, or prospects of the Company, or any mortgage, pledge, or
imposition of any lien or other encumbrance on any asset of the Company,
other than in the ordinary course of business, or any agreement relating to
any of the foregoing or (e) any default or breach by the Company in any
material respect under any contract, license or permit.

         3.10 INVENTORIES. All inventories of the Company are of a quality and
quantity usable and salable in the ordinary course of business, except for
obsolete items and items of below-standard quality, all of which, in the
aggregate, are immaterial in amount.

         3.11 LABOR MATTERS. There are no activities or controversies,
including, without limitation, any labor organizing activities, election
petitions or proceedings, proceedings preparatory thereto, unfair labor practice
complaints, labor strikes, disputes, slowdowns, or work stoppages, pending or,
to the best of the knowledge of Sellers, threatened, between the Company and any
of its employees.

         3.12 TAXES. Except as otherwise provided herein, all Taxes due and

Requirement relating or applicable to any of its properties or assets or to the

material respects in the manner heretofore owned, used and operated by the

generally)which materially and adversely affect or, so far as Sellers can now
reasonably foresee, will materially and adversely affect the business,
prospects, operations or principal properties of the Company or the ability of
any party to perform its obligations under this Agreement.

         11.06    SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION.

         (a) BY SELLERS. Sellers, jointly and severally, agree to indemnify,
defend and hold Buyer and its Affiliates harmless from and against any and all
losses, liabilities, claims, demands, damages, costs and expenses (including
reasonable attorneys' fees and disbursements) of every

                                  -xviii-
<PAGE>

kind, nature and description (collectively, "Claims") sustained by Buyer or
any of its Affiliates based upon, arising out of or otherwise in respect of
(i) the inaccuracy of any representation or warranty of Sellers contained in
this Agreement or in any certificate, agreement, document or instrument
delivered pursuant to this Agreement, or (ii) the breach of any covenant or
agreement, of Sellers contained in this Agreement or in any certificate,
document or instrument delivered pursuant to this Agreement (other than the
non-competition agreement, employment agreements and lease agreement since
only the persons which are parties thereto shall have any liability,
commitment or obligations thereunder) except, that Sellers shall have no
liability pursuant to Section 11.06(a)(i) for the first $15,000 of aggregate
Claims (the "Buyer Basket") and the total amount of such liability shall not
exceed an amount equal to the Purchase Price.

         (b) BY BUYER. Buyer agrees to indemnify, defend and hold Sellers
harmless from and against any and all Claims sustained by Sellers based upon,
arising out of or otherwise in respect of (i) the inaccuracy of any
representation or warranty of Buyer contained in this Agreement or in any
certificate, agreement, document or instrument delivered pursuant to this
Agreement, or (ii) the breach of any covenant or agreement, of Buyer contained

however, that Buyer shall have no liability pursuant to Section 11.06(b)(i) for
the first $15,000 of aggregate Claims (the "Sellers Basket")") and the total
amount of such liability shall not exceed an amount equal to the Purchase Price.

         (c) NOTIFICATION AND DEFENSE OF CLAIMS. Any party seeking information
or reimbursement for Claims hereunder (the "Indemnified Party") shall as
promptly as practicable notify the party from which such indemnification is
sought (the "Indemnifying Party") upon which the Indemnified Party intends to
base a claim for indemnification or reimbursement hereunder; provided, however,
that the failure of an Indemnified Party so to notify the Indemnifying Party
shall not relieve the Indemnifying Party from any liability under this Agreement
to the Indemnified Party with respect to such Claim except to the extent the
Indemnifying Party is actually prejudiced or damaged by the failure to receive
timely notice. In the event of any claims for indemnification or reimbursement,
the Indemnifying Party, at its option, may assume (with legal counsel reasonably
acceptable to the Indemnified Party) the defense of any claim, demand, lawsuit
or other Proceeding brought against the Indemnified Party, which claim, demand,
lawsuit or other Proceeding may give rise to the indemnity or reimbursement
obligation of the Indemnifying Party hereunder, and may assert any defense of
any party; provided, however, that the Indemnified Party shall have the right at
its own expense to participate jointly with the Indemnifying Party in the
defense of any claim, demand, lawsuit or other Proceeding in connection with
which the Indemnified Party claims indemnification or reimbursement hereunder.
Notwithstanding the right of an Indemnified Party so to participate, the
Indemnifying Party shall have the sole right to settle or otherwise dispose of
such claim, demand, lawsuit or other Proceeding on such terms as the
Indemnifying Party, in its sole discretion, shall deem appropriate with respect
to any issue involved in such claim, demand, lawsuit or other Proceeding as to
which (i) the Indemnifying Party shall have acknowledged the obligation to
indemnify the Indemnified Party hereunder and

                                   -xix-
<PAGE>

the settlement is solely for cash or (ii) the Indemnified Party shall have
declined so to participate and, in either case, the Indemnified Party is
provided a full and complete release of Claims.

         (d) SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations and
warranties of the parties to this Agreement shall survive the Closing Date and
shall remain in full force and effect for a period of three years following the
Closing Date; provided, that (i) the representations and warranties related to
Tax matters shall survive until the applicable statute of limitations for any
potential Tax liability has expired, and (ii) representations and warranties
related to environmental claims shall survive indefinitely. The period during
which the representations and warranties shall survive shall be referred to
herein with respect to such representations and warranties as the "Survival
Period"., The Survival Period shall be extended with respect to any claim for
indemnification under Section 11.06 hereof if a written notice asserting the
claim shall have been duly given in accordance with Article XI hereof within the
Survival Period with respect to such matter. Any claim for indemnification made
during the Survival Period shall be valid and the representations and warranties
relating thereto shall remain in effect for purposes of such indemnification
notwithstanding that such claim may not be resolved within the Survival Period.
All representations, warranties and covenants and agreements made by the parties
shall not be affected by any investigation heretofore or hereafter made by and
on behalf of any of them and shall not be deemed merged into any instruments or
agreements delivered in connection with this Agreement or otherwise in
connection with the transactions contemplated hereby.

         (e) EXCLUSIVE RIGHTS AND REMEDIES. The rights and remedies provided in
