count and inspection of the inventory of Seller held for use exclusively in the

INVENTORY").  During such process, Seller and Buyer shall identify the
following items of inventory, Seller's standard product cost of which, per
item, exceeds $25,000:  (a) polyester resins and other polyester based products
that are more than seven (7) months old based on the batch record date of
production thereof, and (b) waxes, catalysts and mold care products that are
more than twelve (12) months old based on the date of shipment thereof to
Seller (collectively, the "NON-CONFORMING GOODS").  Buyer shall purchase all of
the Closing Inventory (including items described in clauses (a) and (b),
Seller's standard product cost of which is $25,000 or less).  The parties shall
negotiate in good faith to determine within three (3) business days after the
Closing Date a mutually agreeable purchase price for all Non-Conforming Goods,
and Buyer shall purchase all of the Non-Conforming Goods at the agreed upon





                                     - 9 -
<PAGE>   19
price.  The purchase price for Non-Conforming Goods sold pursuant to this
Section 1.5 shall be paid by virtue of the Purchase Price Adjustment (as
defined below).

         1.6.      PURCHASE PRICE ADJUSTMENT.  If the Working Capital (as
defined below) at the Closing Date, as determined in accordance with Section
1.7, is less than $26,400,000, then the Purchase Price shall be reduced
dollar-for-dollar by the amount of such deficiency.  If the Working Capital at
the Closing Date, as so determined, is greater than $26,400,000, then the
Purchase Price shall be increased dollar-for-dollar by the amount of such
excess.  For purposes hereof, "WORKING CAPITAL" means (i) the sum of (a) the
market value, as of the Closing Date, of the Raw Materials, (b) Seller's
standard product cost, as of August 1, 1994, of work-in-process and finished
goods being purchased by Buyer hereunder (other than Non-Conforming Goods),
adjusted dollar-for-dollar to reflect the increase or decrease in the market
value of the raw material component of such standard product cost from August
1, 1994 to the Closing Date, (c) the agreed upon purchase price for any Non-
Conforming Goods purchased by Buyer pursuant to Section 1.5, and (d) the face
amount, as of the Closing Date, of the Purchased Accounts Receivable less 3% of
such face amount, less (ii) 0.5% of the sum of (i)(a) and (b).  "PURCHASE PRICE
ADJUSTMENT" means the post-closing adjustment to the Purchase Price pursuant to
this Section 1.6.

         1.7.      DETERMINATION OF WORKING CAPITAL.  (a)  Promptly after the
Closing, Seller (with such assistance as Seller shall reasonably request of
Buyer and its representatives) shall calculate the amount of the Purchase Price
Adjustment based on its books and records of account maintained in accordance
with Seller's standard practices with respect to the Business.  For purposes of
making such calculation, (i) the inventory to be taken into account in such
calculation shall not include any items that are not purchased by Buyer
pursuant to Section 1.5, (ii) the market value of raw materials shall be equal
to the price applicable to such raw materials, delivered to the appropriate
Business Site, as of the Closing Date, and (iii) the face amount of the
Purchased Accounts Receivable shall be computed without taking into account any
allowances against such accounts, including allowances for uncollectible
accounts, warranties and returns.

         (b)       As soon as reasonably practicable following the Closing
Date, but in no event later than twenty (20) days thereafter, Seller shall
deliver to Buyer notice of the amount of the Purchase Price Adjustment
calculated in accordance with Section 1.7(a), showing Seller's calculation in
reasonable detail.  Buyer and its representatives shall be provided complete
access to Seller's books and records and all workpapers and other information
used by Seller to make such calculation.  Such notice, when delivered by Seller
to Buyer, shall be conclusive and binding on the parties for purposes of
determining the





                                     - 11 -
<PAGE>   21
Purchase Price Adjustment, unless Buyer notifies Seller within fifteen (15)
days after receipt of the notice of its disagreement therewith (stating with
reasonable specificity the reasons for any disagreement).  If the disagreement
can not be resolved by the parties within thirty (30) days after Seller
receives notice thereof, payment of the undisputed amount shall be made in
accordance with Section 1.8 and the items in dispute shall be submitted to
arbitration conducted as provided in Section 9.1.

         1.8.      PAYMENT OF PURCHASE PRICE.  The Purchase Price shall be paid
by Buyer to Seller at the Closing as follows:

         (a)       $81,350,000 by wire transfer of federal funds to PNC Bank,
N.A., Pittsburgh, PA, ABA No. 043000096, Credit: Aristech Chemical Corporation
Concentration Account No. 2-948495; and

         (b)       by Buyer's assumption of Seller's liabilities as provided in
Section 1.10.  Any amounts owing Buyer or Seller as a result of a Purchase
Price Adjustment shall be paid by Seller or Buyer to the other, as the case may
be, within ten (10) days after the amount is finally determined pursuant to
Section 1.7, by wire transfer of federal funds.

         1.9.      ALLOCATION OF PURCHASE PRICE.  Buyer and Seller agree that
the Purchase Price shall be allocated among the Purchased Assets in accordance
with the allocation set forth in Schedule 1.9.  Buyer and Seller agree that
each will report the federal,





                                     - 12 -
<PAGE>   22
state and local income and other tax consequences of the purchase and sale
contemplated hereby in a manner consistent with such allocation and that
neither will take any position inconsistent therewith upon examination of any
tax return, in any refund claim, in any litigation, or otherwise.

         1.10.     ASSUMPTION OF LIABILITIES.
         (a)       At the Closing, Buyer shall assume and agree to discharge
and perform promptly when due the following liabilities and obligations of

                   (vi)   Seller's obligation to make severance payments to the
                          Terminated Direct Reports, to the extent provided in
                          Section 1.11(d), and Seller's obligations to make
                          severance payments to those Business Employees
                          employed as drivers in the Distribution component of
                          the Business as provided in Section 1.11(e).  These
                          obligations shall constitute Assumed Liabilities,
                          notwithstanding the extent to which they may have
                          accrued prior to the Closing.

         (b)       All liabilities and obligations of Seller (whether direct or
indirect, material or immaterial, known or unknown, absolute, accrued,
contingent or otherwise) that do not





                                     - 15 -

constitute Assumed Liabilities shall be retained by Seller (collectively, the
"RETAINED LIABILITIES").

         1.11.     CERTAIN EMPLOYEE MATTERS.
         (a)       On or prior to the Closing Date, Buyer shall make offers of
employment, effective as of the Closing Date, to such salaried and hourly
Business Employees as are identified on Schedule 1.11(a) and who are actively
at work with Seller as of the Closing Date.  Buyer shall prescribe the manner
by which such offers may be accepted.  Seller has provided Buyer a written list
of all the Business Employees, which includes the employee's name, social
security number, hourly rate or bi-weekly salary, job title, annual earnings,
date of hire, years and types of service recognized by Seller as of November 9,
1994, as supplemented by the updates of such list as of January 31, 1995 and
March 20, 1995.  Seller represents and warrants that the information on such
list was accurate as of the time specified in such list and, notwithstanding
anything to the contrary in Section 7.1, such representation and warranty shall
survive indefinitely beyond the Closing Date.  Buyer has notified Seller of the
names of all the Business Employees, who have accepted offers of employment
(the "TRANSFERRED EMPLOYEES").

         (b)       Except as may otherwise be expressly provided in this
Section 1.11(b), the Transferred Employees shall be treated as newly hired
employees of Buyer.

                   (i)    The offer of employment, if accepted, will not
                          provide for any certain term of employment, and all
                          who accept such offer shall be employees-at-will of
                          Buyer.  Buyer shall pay the Transferred Employees
                          wages that are substantially equivalent to those paid
                          the Transferred Employees by Seller immediately prior
                          to Closing, and shall assign each of the Transferred
                          Employees duties and responsibilities that are
                          substantially equivalent to those assigned such
                          Transferred Employee by Seller immediately prior to
                          Closing.  Buyer shall also provide the Transferred
                          Employees a package of benefits that is suitable in
                          light of the Transferred Employees' particular
                          circumstances.

                   (ii)   The Transferred Employees shall be eligible to
                          participate in the qualified and non-qualified
                          pension, stock bonus, profit sharing and retirement
                          plans (except for the Ashland Oil, Inc. Leveraged
                          Employee Stock Ownership Plan, unless and until some
                          or all of the Transferred Employees become members of
                          a designated eligible group for participation
                          thereunder under the procedures generally applicable
                          for acquired employees) in which similarly situated
                          employees of Buyer participate, and Buyer and such
                          plans shall recognize, solely for purposes of
                          eligibility and

                          said plans, the Transferred Employees' years of
                          credited service with Seller prior to the Closing
                          Date.  Buyer shall amend said plans as of the Closing
                          Date to recognize such service with Seller; provided,
                          however, that nothing herein shall be construed as
                          conferring on any Transferred Employee any right to,
                          in or under any such plan of Buyer other than pursuant
                          to the terms of such plans, as so amended, and as from
                          time to time in effect.

                   (iii)  The Transferred Employees shall be eligible to
                          participate in health and life plans (including
                          accidental death and dismemberment plans) in which
                          similarly situated employees of Buyer are eligible to
                          participate, and Buyer and such plans shall recognize,
                          solely for the purposes of eligibility under Buyer's
                          said health and life (and accidental death and
                          dismemberment) plans, the Transferred Employees'
                          employment with Seller prior to the Closing Date. Such
                          recognition of prior service shall also count for
                          purposes of determining whether any Transferred
                          Employee becomes eligible for any retiree health,
                          retiree life or retiree accidental death and
                          dismemberment plan benefits. Buyer shall amend said
                          plans as of the Closing

                          Date to recognize such service with Seller; provided,
                          however, that nothing herein shall be construed as
                          conferring on any Transferred Employee any right to,
                          in or under any such plan of Buyer other than pursuant
                          to the terms of such plans, as so amended, and as from
                          time to time in effect.  The eligibility of
                          Transferred Employees to participate in Buyer's health
                          and life plans shall not be delayed or limited in any
                          way by pre-existing conditions; provided, however,
                          that the applicable proof of health conditions in such
                          plans shall be applied pursuant to their terms if any
                          Transferred Employee fails to timely enroll himself or
                          herself or his or her dependents (when dependent
                          coverage is applicable and available) within thirty
                          (30) days of first becoming eligible.  All claims
                          incurred with regard to any Transferred Employee
                          before the Closing Date and which are covered under
                          the applicable health, life or accidental death and
                          dismemberment plans of Seller shall be payable under
                          the terms of the applicable plan of Seller.  All other
                          claims incurred with regard to any Transferred
                          Employee and which are covered under the applicable
                          health, life or accidental death or dismemberment
                          plans of Buyer shall be payable under the terms of the
                          applicable plan of Buyer.  The Transferred

<PAGE>   29
                          Employees who participated in health maintenance
                          organizations ("HMOs") immediately prior to the
                          Closing shall be provided the opportunity to enroll in
                          the Buyer's indemnity plan on the same terms and
                          subject to the same conditions as the Transferred
                          Employees who did not so participate in HMOs.  All the
                          Transferred Employees shall be offered participation
                          in the HMOs available to other similarly situated
                          employees of the Buyer at the time and in the same
                          manner as such participation is ordinarily offered.

                   (iv)   The Transferred Employees shall be eligible to
                          participate in sick pay and short term and long term
                          disability plans in which similarly situated employees
                          of Buyer are eligible to participate. Buyer shall
                          recognize for purposes of such plans the Transferred
                          Employees' employment with Seller prior to the Closing
                          Date.  Buyer shall amend said plans as of the Closing
                          Date to recognize such service with Seller; provided,
                          however, that nothing herein shall be construed as
                          conferring on any Transferred Employee any right to,
                          in or under any such plan of Buyer other than pursuant
                          to the terms of such plans, as so amended, and as from
                          time to time in effect.

                   (v)    The Transferred Employees shall be eligible for other
                          benefits in which or policies under which similarly
                          situated employees of Buyer are eligible.  Buyer
                          shall recognize for purposes of such plans the
                          Transferred Employees' employment with Seller prior
                          to the Closing Date.  Buyer shall amend said benefits
                          and policies as of the Closing Date to recognize such
                          service with Seller; provided, however, that nothing
                          herein shall be construed as conferring on any
                          Transferred Employee any right to, in or under any
                          such benefits and policies of Buyer other than
                          pursuant to the terms of such benefits and policies,
                          as so amended, and as from time to time in effect.
                          The Transferred Employees shall be eligible for paid
                          vacation benefits under the policies of the Buyer
                          that apply to similarly situated employees of the
                          Buyer and, for this purpose, the Transferred
                          Employees' service with the Seller prior to the
                          Closing Date shall be counted.

                   (vi)   Buyer shall use its best efforts to notify Seller of
                          the termination of employment or reemployment of any
                          Transferring Employee.  Such notification shall be
                          made within thirty (30) days of the date of
                          termination of employment or reemployment.

         (c)       For purposes of the COBRA health continuation of coverage
provisions (hereafter referred to as the "COBRA PROVISIONS") contained in
Section 4980B(f) of the Internal Revenue Code of 1986 and in Sections 601
through 608 of the Employee Retirement Income Security Act of 1974 ("ERISA"),
the Transferred Employees shall be considered to have undergone a termination
of employment with Seller.  It is the understanding and intention of the Seller
and Buyer that no group health plan maintained by Buyer shall constitute a
successor plan to any of the Seller's group health plans and the Buyer is not a
successor employer with respect to any of the Seller's group health plans and
the Seller is not a predecessor employer with respect to the Buyer's group
health plans, within the meaning of the COBRA Provisions.  It is the further
understanding and intention of Seller and Buyer, however, that the health plan
coverage to be afforded to the Transferred Employees pursuant to Section
1.11(b)(iii) shall be coverage that, pursuant to Section 602(2)(D)(i) of ERISA,
terminates any continuation coverage rights the Transferred Employees might
otherwise have under the COBRA Provisions as a result of termination of
employment with Seller.

         (d)       (i)      Subject to clause (ii) of this Section 1.11(d), the
parties agree that responsibility for all amounts paid ("SEVERANCE PAYMENTS")
to any Business Employee (including any Transitional Employee, as defined in
Section 4.5(a)) who is a Direct Report (as defined below) and who is ultimately
successful





                                     - 22 -
<PAGE>   32
in collecting any benefits under Seller's severance plan or policies based on
such Business Employee's termination prior to January 1, 1997 in connection
with the transactions contemplated hereby ("TERMINATED DIRECT REPORT") shall be
allocated as follows: All Severance Payments made to the first fifty-five (55)
Terminated Direct Reports shall be for Seller's account, and all Severance
Payments made to all other Terminated Direct Reports shall be for Buyer's
account.  Any Business Employees employed by Seller at the Neville Island
Facility who are terminated at any time before January 1, 1997 shall constitute
Terminated Direct Reports to the extent they are successful in collecting
Severance Payments as hereinabove provided.  The drivers referred to in Section
1.11(e) shall not be deemed Terminated Direct Reports for purposes of this
paragraph (d).  For purposes of this Section 1.11(d), the term "DIRECT REPORTS"
shall mean those employees of Seller 100% of whose time is charged to the
Business based on Seller's policies in effect immediately prior to Closing and
shall not include such employees as corporate attorneys, accounting staff and
information services personnel whose time is not charged 100% to the Business
on such basis.
                   (ii) (A)       In the event that more than fifty-five (55)
Direct Reports who are entitled to Severance Payments are terminated within
thirty (30) days of Closing, the average Severance Payment payable to all such
Direct Reports terminated within thirty (30) days of Closing shall be
calculated, and Seller shall be deemed to have satisfied all of its obligations





                                     - 23 -
<PAGE>   33
under Section 1.11(d) upon making Severance Payments to Terminated Direct
Reports (regardless of the number of such Terminated Direct Reports) in an
aggregate amount equal to fifty-five (55) times such average Severance Payment.
All Severance Payments in excess of the amount specified in the foregoing
sentence shall be paid by Buyer.

                   (B)    In the event that less than fifty-five (55) Direct
Reports who are entitled to Severance Payments are terminated within thirty
(30) days of Closing, Seller shall pay the actual Severance Payments for the
first fifty-five (55) Terminated Direct Reports who shall be determined in
accordance with the order in which Seller makes Severance Payments to
Terminated Direct Reports, and Buyer shall pay the actual Severance Payments
for all other Terminated Direct Reports.

                   (iii)  Seller shall notify Buyer of any Severance Payments
made to Terminated Direct Reports for Buyer's account pursuant to Section
1.11(d).  Buyer shall reimburse Seller in full therefor within five (5) working
days after Buyer's receipt of such notice.  Any amount not reimbursed within
such five-day period shall bear interest, from the date the corresponding
Severance Payment was made by Seller until the date such amount is reimbursed
to Seller, at the prime lending rate charged by Mellon Bank, N.A. during such
period.
         (e)       Buyer shall pay all amounts payable to any Business Employee
employed by Seller as a driver in connection with the


                                     - 24 -
<PAGE>   34
Distribution component of the Business who is ultimately successful in
collecting any benefits under Seller's severance plan or policies based on such
Business Employee's termination in connection with the transactions
contemplated hereby.  Seller shall notify Buyer of any such payments made to
such Business Employees, and Buyer shall reimburse Seller in full therefor
within five (5) working days after Buyer's receipt of such notice.  Any amount
not reimbursed within such five-day period shall bear interest, from the date
the corresponding severance payment was made by Seller until the date such
amount is reimbursed to Seller, at the prime lending rate charged by Mellon
Bank, N.A. during such period.

         (f)       Except as provided in Section 1.10(a)(vi), it is expressly
agreed and acknowledged by the parties hereto that Buyer has assumed no
liability for any wages or benefits that Seller or any of its affiliates
provided to Seller's employees including, but not limited to, retiree medical
benefits, retiree life insurance benefits, benefits under the COBRA Provisions,
employment contracts, qualified or non-qualified retirement benefits, and
benefits which could be payable with respect to services, expenses or other
events that occurred prior to the Closing Date under any plan, policy or
program of the Seller.

         1.12.     CONTINUING LIABILITIES.
         (a)       The term "CONTINUING LIABILITY" shall mean any liability
that commences, or that arises from facts in existence, prior to the Closing
and that continues, or the facts giving rise to which continue, to exist after
the Closing.  Subject to clause (b), Seller is indemnifying Buyer against
Continuing Liabilities to the extent arising from Seller's operation of the
Business prior to Closing pursuant to Section 7.3(e), and Buyer is indemnifying
Seller against Continuing Liabilities to the extent arising from Buyer's
operation of the Business after Closing pursuant to Section 7.4(d).

         (b)       Within ten (10) days after either party receives notice or
otherwise becomes aware of the existence of a Continuing Liability as to which
such party intends to seek indemnification from the other party, such party
shall notify the other party.   Either party's failure to so notify the other
of a Continuing Liability, shall constitute a waiver by the failing party of
all rights to indemnification by the other arising from such Continuing
Liability.   Promptly after the delivery of such notice, Seller and Buyer shall
consult with each other in good faith to develop a joint strategy for defending
against the Continuing Liability, including allocation of the costs of such
defense.

         (c)       In the event that a claim is made against only one of the
parties as a result of a Continuing Liability, such party





                                     - 26 -
<PAGE>   36
shall not be entitled to any indemnification by the other party with respect to
such claim unless such party permits the other party to participate in and
control the defense of such claim jointly and equally with it.  Notwithstanding
the foregoing, the party against which the claim is made may, after consulting
the other party, settle such claim in its sole discretion; provided that such
party obtains as a condition to such settlement a full and complete release of
the other party from all claims arising from such Continuing Liability.

         (d)       If a third party makes a claim against both Seller and
Buyer, or if both Seller and Buyer are otherwise called upon to defend a claim
arising from a Continuing Liability, each of Seller and Buyer shall separately
defend itself against such claim with representatives of its choosing, unless
the parties otherwise agree.

         (e)       Any determination of the extent to which a Continuing
Liability arises from Seller's operation of the Business prior to Closing or
Buyer's operation of the Business after Closing (a "DETERMINATION"), shall be
subject to the following:

                   (i) To the extent that a court hearing a claim arising from
                   a Continuing Liability makes a final, non-appealable
                   Determination, the parties shall be bound thereby.

                   (ii) In all other cases, the parties shall attempt in good
                   faith to agree upon a Determination.  If the parties are
                   unable jointly to make a Determination, the matter


                                     - 27 -
<PAGE>   37
                   shall be submitted to the alternative dispute resolution
                   procedure described in Section 9.1.

                   (iii) Any Determination shall be made by consideration of
                   all the factors relevant to the causation of such Continuing
                   Liability.  For purposes of illustration and not in
                   limitation of the foregoing, in the case of a Continuing
                   Liability arising from occupational injury or disease to
                   persons employed by both Seller and Buyer the relevant
                   factors shall include without limitation the duration and
                   extent of exposure to operative conditions while an employee
                   of each party.  The date of manifestation of injury or
                   disease shall not be solely determinative of the date on
                   which the exposure commenced, but shall be a relevant factor
                   for consideration.


         1.13.     CERTAIN CONSENTS.  Nothing in this Agreement shall be
construed as an attempt to assign any contract, agreement, permit, franchise,
or claim included in the Purchased Assets which is by its terms or in law
nonassignable without the consent of the other party or parties thereto, unless
such consent shall have been given, or as to which all the remedies for the
enforcement thereof enjoyed by Seller would not, as a matter of law, pass to
Buyer as an incident of the assignments provided for by this Agreement.  In
order, however, to provide Buyer the full benefits of every contract,
agreement, permit, franchise and claim of the character described in the
immediately preceding sentence, Seller shall, to the extent reasonably
necessary and at Buyer's cost, cooperate with Buyer in any reasonable
arrangement designed to provide the benefits thereof to Buyer.  Without
limiting the generality of any provision contained elsewhere herein, the
non-assignment of the foregoing shall not, to the





                                     - 28 -
<PAGE>   38
extent the liabilities hereunder would have been Assumed Liabilities but for
this Section 1.13, affect the status of such liabilities as Assumed
Liabilities.  Nothing in this Section shall in any way diminish Seller's
obligations hereunder to obtain all consents and approvals prior to or at
Closing as are necessary to enable Seller to convey or assign good and valid
title to all the Purchased Assets to Buyer.

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

Schedules 1.2(h), 1.2(i), 1.2(k), 1.10(a)(iii), 2.7 and 2.9, Seller is not a
party to or bound by any lease, contract or

materially impair Seller's ability to conduct the Business at any of its plants
in Bartow, Florida, Jacksonville, Arkansas, Colton, California or Neville
Island, Pennsylvania, or at any of its Distribution facilities (collectively,
the "BUSINESS SITES").  Seller is not aware that it has failed to comply with
any laws and regulations applicable to the Business or the Purchased Assets,
except for failures to comply that do not presently materially impair Seller's

<PAGE>   45
         2.10.     TITLE.  (a)  Seller has good title to all of the Purchased
Assets (other than real property and interests therein and the Purchased
Intellectual Property), and none of such property is subject to any mortgage,
pledge, lien, restriction, encumbrance, license, covenant, claim, security
interest, charge or any other matter affecting title, except (i) minor items,
none of which materially detracts from the value of or impairs the use of the
affected property, (ii) mechanics', carriers', workmen's, repairmen's or other
like liens arising in the ordinary course of business, (iii) liens for current
taxes, assessments and other governmental charges not yet due and payable, and
(iv) as disclosed on Schedule 2.10(a) (all of the foregoing referred to
collectively as the "PERMITTED ENCUMBRANCES").  This paragraph (a) does not
apply to real property or interests in real property, such items being the
subject of Section 2.10(b), or to the Purchased Intellectual Property, which is
the subject of Section 2.12 below.  Seller acknowledges that it shall remain
responsible for satisfying the obligations secured by the liens referred to in
clauses (ii), (iii) and (to the extent not assumed by Buyer hereunder) (iv),
when and as such obligations become due and payable.

         (b)       Schedules 1.2(a), 1.2(b), 1.2(h) and 2.9 set forth a correct
description of all real property and interests in real property included in the
Purchased Assets.  Buyer has received a title commitment report for and survey
of each parcel of land included in the Real Estate (collectively, the "TITLE
COMMITMENT





                                     - 36 -
<PAGE>   46
REPORTS" and the "SURVEYS," respectively).  Seller has (a) good fee title to
all real property and interests in real property shown on Schedules 1.2(a) and
1.2(b) owned by it and (b) to Seller's knowledge, good leasehold interests in
all real property subject to the leases described in Schedules 1.2(h) and 2.9
and leased by it, in each case free and clear of all mortgages, liens, security
interests, easements, covenants, rights-of-way and other encumbrances or
restrictions of any nature whatsoever, except (i) Permitted Encumbrances, (ii)
easements, covenants, rights-of-way and other encumbrances or restrictions of
record, (iii) zoning and other similar restrictions, (iv) unrecorded easements,
covenants, rights-of-way or other restrictions that do not materially impair
the use of the property to which they relate in the Business as presently
conducted and (v) as otherwise shown on the Title Commitment Reports and the
Surveys.  Seller acknowledges that it shall remain responsible for satisfying
the obligations secured by the liens referred to in clauses (ii), (iii) and (to
the extent not assumed by Buyer hereunder) (iv), of Section 2.10(a), when and
as such obligations become due and payable.

by Business Employees pending, or to the knowledge of Seller, threatened; and
(d) there is no pending labor grievance by any Business Employee.

         2.12.     INTELLECTUAL PROPERTY RIGHTS.  The Purchased Intellectual
Property, together with the Retained Intellectual Property, constitutes all
intellectual property rights that are owned, licensed or used by Seller and
that are material to the Business.  Seller's retention of the Retained
Intellectual Property will not materially impair Buyer's ability to conduct the
Business.  Seller owns, or has the right to use without interference from any
other party, all of the Purchased Intellectual Property.  No claim, suit or
action is pending, or, to the knowledge of Seller, threatened, against Seller,
alleging that Seller is infringing upon the intellectual property rights of
others in the conduct of the Business or challenging the validity of the
Purchased Intellectual Property, or alleging that Seller's use of the Purchased
Intellectual Property infringes or conflicts with the rights of others.  Seller
is not aware that it is infringing upon the intellectual property rights of
others in the conduct of the Business.

         2.13.     ENVIRONMENTAL MATTERS.  Except as set forth in Schedule 2.13
and except for those matters referred to in Buyer's document entitled "Project
A Site Issues" dated December 16, 1994 with respect to the Business Sites (the
"BUYER ENVIRONMENTAL REPORT"), Seller has not, with respect to the Real Estate,
the





                                     - 38 -

violation is currently existing and has caused, or if not corrected, will
cause, a material adverse change to the operations, properties, assets,
liabilities or financial condition of the Business or of any element thereof,
i.e., UPR, MA or Distribution.

         2.14.     SUFFICIENCY OF THE ASSETS.  The Purchased Assets, together
with the Retained Assets, constitute sufficient assets for Seller's operation
of the Business as presently conducted.

         2.15.     MAINTENANCE OF EQUIPMENT.  The equipment being purchased by
Buyer hereunder has been maintained by Seller in all material respects in
accordance with the standard maintenance policies of Seller in effect during
Seller's ownership thereof.

         2.16.     CUSTOMERS AND SUPPLIERS RELATIONS.  Seller has not received
any notice that (a) any single customer of the Business that accounted for more
than 5% of the total net sales of the Business for the twelve-month period
ended on December 31, 1994, or (b) any current supplier that is material to the
Business and  could not be replaced by Seller at substantially comparable cost,
will terminate its business relations with Seller.

         2.17.     Tax Matters.   Seller has timely paid all federal, state and
local income, profit, franchise, sales, use, employment and similar taxes, and
all interest and penalties thereon due and payable by it as of the Closing
Date, and has filed all federal, state and local tax returns which have been
required to be filed on or prior to the Closing Date, the non-payment of or
failure to file which would result in a lien or encumbrance on any Purchased
Asset, or would result in Buyer becoming liable or responsible therefor.
Seller will timely pay all tax liabilities, assessments, and interest and
penalties thereon that have accrued but that are not yet due and payable, the
non-payment of which would result in a lien or encumbrance on any Purchased
Asset or would result in Buyer becoming liable therefor.  All ad valorem and
other taxes (excluding income taxes) assessed against the Purchased Assets and
payable as of the Closing Date have been paid.  Seller shall file all ad
valorem tax returns for the Purchased Assets held by Seller on assessment date
January 1, 1995, or on any other assessment date occurring prior to the
Closing.

         2.18.     VIOLATION OF CERTAIN LAWS.  To its knowledge, Seller has
not, with respect to the Business, taken or agreed to take any action in
violation of the Foreign Corrupt Practices Act or the Export Administration
Act.

         2.19.     FINDERS' FEES.  Neither Seller nor any of its officers,
directors or employees has made any agreement or taken





                                     - 40 -
<PAGE>   50
any other action that might cause Buyer to become liable for any brokerage
fees, commissions or finders' fees in connection with the transaction
contemplated hereby and by Seller's Ancillary Documents.

         2.20.     ACCURACY OF REPRESENTATIONS AND WARRANTIES.  No
representation or warranty by Seller in this Agreement or in any of Seller's
Ancillary Documents, or in any Exhibit, certificate or other instrument
furnished to Buyer by Seller pursuant hereto or thereto, contains or will
contain, as of the time made, any untrue statement of a material fact;
provided, however, that Seller shall not be deemed to have breached this
representation as a result of any inaccuracy arising from (a) facts that
generally apply to or affect businesses in the industries in which the Business
is operated, or (b) facts or matters that are the subject of, or that are
purported to be excluded from, any other representation or warranty made by
Seller in any such agreement or instrument.

         2.21.     LIMITATION ON SELLER'S WARRANTIES.  BUYER AGREES THAT IT IS

BUSINESS INFORMATION" means all information of any kind relating directly to
the Business, including the Purchased Intellectual Property, financial data,
projections, marketing information, reports, process designs, economics, and
any and all drawings, engineering, data specifications and other information
regarding the Business.  The term "OTHER CONFIDENTIAL INFORMATION" means the

which (i) becomes generally available to the public other than as a result of a
disclosure by Seller or Buyer, respectively, or their respective
representatives, or (ii) becomes available to Seller or Buyer, respectively, on
a non-confidential basis from a source other than Buyer or Seller,
respectively, or their respective representatives, provided that such source is
not bound by a confidentiality agreement with Buyer or Seller, respectively.
The term "Other Confidential Information" also excludes information which was

<PAGE>   56
Buyer on a non-confidential basis prior to its disclosure to Buyer by Seller or
its representatives.

         (e)       Without limiting any other rights or remedies available to
the parties, each of Seller and Buyer will be entitled to equitable relief
(including without limitation injunctive relief) for any breach or failure to
abide by the provisions of this Section 4.1.

         4.2.      PUBLICITY.  Except as may be required by applicable law or
by applicable stock exchange rules, press releases and other publicity
concerning this transaction (including without limitation statements to
customers) shall be made only with the prior agreement of Seller and Buyer as
to the form, content and timing thereof (and, in any event, Seller and Buyer
shall use all best efforts to consult and agree with each other with respect to
the form, content and timing of any such required press release or other
publicity).  The foregoing shall not apply to Buyer's communications with
investment bankers and other professionals in the investment community.

         4.3.      ACCESS TO AND PRESERVATION OF INFORMATION AND RECORDS.  For
a period of ten (10) years following the Closing Date or for the period
indicated by the respective party's record retention policy, whichever is
shorter, each of Buyer and Seller shall preserve the books and records of the
Business and shall provide such access to such books and records as the other
party shall





                                     - 47 -

reasonably request for purposes of preparing tax reports or returns required to
be filed by each other party, and responding to audits thereof.  Buyer and
Seller shall also provide written notice to the other party not less than
thirty (30) days prior to destroying any such books or records, and shall
permit such other party to take possession thereof.  Buyer and Seller shall
also provide the other party such information as such other party shall
reasonably request for such purposes.

         4.4.      COOPERATION.  From and after the Closing Date, each of Buyer
and Seller shall provide to the other such assistance and such access to its
employees and to the records referred to in Section 4.3, and shall otherwise
cooperate fully with the other, as shall be reasonably necessary in connection
with any threatened, pending or future demand, claim, action, cause of action,
suit or proceeding related to the Business, whether or not arising out of
events occurring prior to, on or after the Closing Date.

         4.5.      TRANSITION PERIOD.
         (a)       During the Transition Period (as hereinafter defined),
Seller shall provide to Buyer the services on a full-time basis of the
employees of Seller identified in Schedule 4.5(a) (the "TRANSITIONAL
EMPLOYEES"); provided, that such persons do not elect, of their own initiative,
to terminate their employment with Seller during such period.  During the
Transition Period, the Transitional Employees shall perform such services
related to





                                     - 48 -
<PAGE>   58
the conduct of the Business as Buyer shall determine from time to time.  Seller
shall be responsible for all personnel matters regarding the Transitional
Employees.  Such matters shall include, but not be limited to, promotions,
transfers, compensation, employee benefits, performance evaluations, all
disciplinary actions up to and including termination of employment and
compliance with all applicable employment and tax laws and related regulations
at the federal, state and local level, including income tax withholding and
payment of the employer and employee share of employment and unemployment tax.
Seller shall have the final decision to terminate employment of any
Transitional Employees.  Notwithstanding the foregoing sentence, Buyer retains
the right to cease using the services of any particular Transitional Employee
at any time as Buyer deems appropriate.  Seller agrees that the Transitional
Employees shall observe those work hours at work locations of the Business as
determined by Buyer's on-site supervisory officials.  Seller shall consult with
Buyer in order to attempt to resolve all questions and needs of Buyer regarding
the work hours of the Transitional Employees.  During the Transition Period,
Seller may redeploy any Transitional Employee within Seller's own organization;
provided that Seller places another of Seller's employees in the position from
which the Transitional Employee is so redeployed.

         (b)       It is expressly acknowledged by the parties hereto that
nothing in this Agreement is intended or shall be construed





                                     - 49 -
<PAGE>   59
to create an employer/employee relationship between Buyer and the Transitional
Employees and it is expressly agreed and acknowledged by the parties that
Seller is the common law employer of the Transitional Employees.  In the event
the Internal Revenue Service or any other governmental agency should question
or challenge the employment status of the Transitional Employees, the parties
hereto agree that both Seller and Buyer shall have the right to participate in
any discussion or negotiation occurring with such agency or agencies,
irrespective of with whom or by whom such discussion or negotiation is
initiated.

         (c)       During the Transition Period, Seller shall use commercially
reasonable efforts to provide such additional assistance to Buyer as Buyer
shall request in order to effect the orderly transition from Seller's to
Buyer's operation of the Business.  Such assistance may include receiving
orders and inquiries from customers of the Business and directing such orders
and inquiries to Buyer, assisting Buyer in developing computer services to
support the Business and providing such interim computer services to Buyer.

         (d)       Seller shall not charge Buyer any fee for the services of
the Transitional Employees provided pursuant to Section 4.5(a) or for any
transitional assistance provided by Seller pursuant to Section 4.5(c), except
that within thirty (30) days after demand therefor, Seller shall reimburse
Buyer for all reasonable travel expenses incurred by Transitional Employees or
any other employee





                                     - 50 -

in providing services to or for the benefit of Seller pursuant to Section
4.5(a) or 4.5(c).

         (e)       The "TRANSITION PERIOD" shall be the ninety (90) day period
immediately following the Closing Date; provided, however, that Buyer may
extend the Transition Period for additional thirty (30) day periods by giving
written notice to Seller at least ten (10) days prior to the date that the
Transition Period would otherwise expire; provided further, however, that in no
event shall the Transition Period extend beyond one hundred and eighty (180)
days following the Closing Date.

         (f)       Buyer agrees to release, indemnify, defend, save and hold
Seller and its officers, directors, employees, agents, successors and permitted
assigns (any or all of the foregoing hereinafter referred to as an "INDEMNIFIED
PERSON"), harmless from and against any and all demands, claims, actions or
causes of action, assessments, losses, damages, deficiencies, liabilities,
costs and expenses (including but not limited to reasonable attorneys' fees and
expenses, and the aggregate amount paid in reasonable settlement of any
actions, suits, proceedings, or claims, or threats thereof, to which any
Indemnified Person may become subject under any statute or common law or
otherwise), asserted against, imposed upon, resulting to or incurred by any
Indemnified Person, directly or indirectly, as a result of or in connection
with any claim directly or indirectly based on or arising from the performance
of services for Buyer by Seller or





                                     - 51 -
<PAGE>   61
the Transitional Employees pursuant to this Section 4.5.  The parties
acknowledge that it is the intent of this Section 4.5(f) that Seller bear no
cost or liability of any nature whatsoever (whether arising from claims made by
the Transitional Employees or by others as a result of the acts of Transitional
Employees or otherwise) as a consequence of Seller's provision of transitional
services to Buyer pursuant to this Section 4.5.  The foregoing indemnification
provisions shall survive the Closing and completion of the services rendered to
Buyer by Seller and the Transitional Employees hereunder, shall be in addition
to any other liability which Buyer may otherwise have to Seller, and shall
inure to the benefit of the heirs, personal representatives, successors and
assigns of each Indemnified Person.

         4.6.      NON-COMPETITION AND NON-INTERFERENCE BY SELLER.
         (a)       Except as otherwise required by law, regulation or a court
of competent jurisdiction, Seller shall not, for a period of two (2) years

directly or indirectly provide any advisory or consulting services for, invest
in (other than stock in a publicly held corporation which is traded on a
recognized securities exchange) or otherwise operate any corporation,
partnership, organization, proprietorship, or other entity which develops,
manufactures, sells or distributes unsaturated polyester resins or maleic
anhydride in competition with the Business in each of the states in the United

Distribution, or (ii) intentionally and knowingly induce or attempt to induce
any supplier, employee, agent or other representative or associate of Buyer
involved in the Business as conducted by Buyer to terminate its relationship
with Buyer.

         (b)       Notwithstanding the foregoing, the following shall not
constitute a breach by Seller of Section 4.6(a): (i) Seller's production,
whether through its ownership of Avonite, Inc. or otherwise, of solid surfacing
materials using polyester resins as feedstock; or (ii) Seller's hiring of any
person who voluntarily, and without inducement by Seller, seeks employment by
Seller.

         (c)       Notwithstanding Section 4.6(a), Seller shall have complete
freedom to develop, patent, test market, produce, have toll produced, market,
license others, sell and conduct all other business related to all Retained
Intellectual property as contained in Schedule 1.3(k) as well as any
continuations, divisions, reissues, continuations-in-part, foreign counterpart

dimethacrylates, hereinafter referred to as "LOER" such as described in U.S.
Patent 5,292,841 and patent applications listed on Schedule 1.3(k) having the
title "Laminating Resins Having Low Organic Emissions."  Seller shall provide
Buyer the opportunity to produce LOER under non-exclusive license and shall
give Buyer an opportunity to toll produce Hyrizon and LOER for market

parties agree to the terms thereof.  Buyer shall be considered to have received
confidential information associated with products included in Schedule 1.3(k)
by nature of this transaction and shall keep confidential all related
information and shall not produce, sell, or otherwise practice business related
to products described in Schedule 1.3(k) without written consent from Seller.

         (d)       Seller acknowledges that in the event of any breach of the
covenants set forth in clause (a) of this Section 4.6, Buyer and its successors
and permitted assigns shall be entitled to injunctive relief and to such other

<PAGE>   64
attempt to induce any supplier, employee, agent or other representative or
associate of Seller to terminate its relationship with Seller.  Notwithstanding
the foregoing, Buyer's hiring of any person who voluntarily and without
inducement by Buyer, seeks employment with Buyer shall not constitute a breach
by Buyer of this Section 4.7.  Buyer acknowledges that in the event of any
breach of this Section 4.7, Seller and its successors and permitted assigns
shall be entitled to injunctive relief and to such other and further relief as
is proper in the circumstances.

         4.8.      IDENTIFICATION OF GOODS.  Buyer shall assure that any goods

distributor thereof or otherwise referring to Seller in any way.

         4.9.      RETURN OF POLYESTER RESINS.

         (a)       Buyer shall notify Seller if any customer of the Business,
                   claiming that polyester resins shipped by Seller prior to
                   the Closing Date do not conform to the specifications
                   applicable thereto, returns such resins to Buyer within
                   ninety (90) days after Seller's shipment thereof.  Upon
                   receipt of such notification, Seller may request such
                   verification and documentation





                                     - 55 -

                   of the alleged non-conformity and the return date as Seller
                   shall reasonably request.

         (b)       Seller shall have no liability for any polyester resins so
                   returned that are returned more than ninety (90) days after
                   Seller's shipment thereof or that conform to applicable
                   specifications.  Any credit offered the customer, other
                   concession made or any cost incurred by Buyer in connection
                   with such resins shall be solely for the account of Buyer.

         (c)       Subject to the following sentence, if the returned polyester
                   resins do not conform to applicable specifications, Buyer
                   shall re-work the returned resin, and Seller shall pay Buyer
                   $.30 per pound of resin so re-worked, plus reasonable

                   the customer and for the customer's return, plus an amount
                   equal to Seller's standard product cost of the resin as of
                   the date of Closing based on Seller's accounting records.

                   accepted by customers due to deviations from applicable
                   specifications, but which resins can be adjusted and
                   reshipped, Seller shall pay Buyer $.15 per pound of affected
                   resins, plus reasonable freight charges for the customer's
                   return and for reshipping the adjusted resin to the

                   not conform with applicable specifications shall be the sole
                   responsibility of Buyer and any credits or other concessions
                   granted to the customer by Buyer in respect of the returned
                   resins shall be solely for the account of Buyer.

cleaning, Buyer shall pay Seller at Closing $50,000 in addition to the Purchase
Price.  Any costs incurred for such cleaning in excess of such amount shall be
solely for Seller's account.  Any waste generated as a result of such cleaning

generated at the Properties, or (iii) the shipment or arrangement for treatment
or disposal by Seller of Pre-Closing Waste.

         (b)       INVENTORY AND DISPOSITION OF PRE-CLOSING WASTE MATERIALS.
Prior to Closing, Seller and Buyer have jointly inventoried and listed the
hazardous and non-hazardous wastes present at the Properties.  Seller has used
all reasonable efforts to remove such Pre-Closing Waste from the Properties
prior to Closing.  To the extent that such Pre-Closing Waste has not been
removed from the Properties prior to Closing, Seller agrees to arrange for
proper shipment, treatment and disposal of such wastes within sixty (60) days
of Closing (unless Seller is precluded from such action by applicable law, in
which case Seller shall arrange for proper shipment, treatment and disposal of
such waste as soon as practicable.  If Seller fails or is unable to take such
action, Seller shall reimburse Buyer for any expenses incurred by Buyer in
arranging for the shipment, treatment and disposal of such wastes at a facility
acceptable to Seller and Seller shall indemnify Buyer Indemnitees pursuant to
clause (a) above with respect to such wastes).

         (c)       POST-CLOSING SHIPMENTS/TREATMENT/DISPOSAL.  Buyer shall be
responsible for, and agrees to indemnify, defend, save and hold harmless Seller
Indemnitees from and against any Claims arising from the shipment after the
Closing Date of any Regulated Substances, or for the arrangement by Buyer for

generated at the Properties.  In no event shall Buyer be required to indemnify,
hold harmless or defend Seller Indemnitees against any Claims arising from the
shipment or arrangement for treatment, storage or disposal of Pre-Closing Waste
at Off-Site Locations, regardless of when such Pre-Closing Waste is shipped.

         (d)       INDEMNIFICATION FOR FAILURE TO HOLD REQUIRED GOVERNMENTAL
APPROVALS.  Seller agrees, for a period of one (1) year after Closing, to
indemnify, defend, save and hold harmless Buyer Indemnitees from and against
Claims arising from failure of Seller to have obtained and hold any
Governmental Approval required under applicable Environmental Law as of the
Closing Date in order to conduct the Business at the Business Sites in the
manner in which it was conducted as of the Closing Date.

         (e)       INDEMNIFICATION FOR PRE-CLOSING VIOLATIONS.  Seller agrees
to indemnify, defend, save and hold harmless Buyer Indemnitees from and against
any enforcement proceedings or penalties relating to alleged violations of
Environmental Laws that occurred prior to the Closing Date resulting from
operation of the Business.  This clause (e) does not cover:

                   (i)    Any Claims relating to violations occurring after the
                          Closing Date (including any allegations of violations
                          by Buyer resulting from Buyer's continuation of any
                          pattern or practice





                                     - 87 -
<PAGE>   97
                          established or engaged in by Seller prior to the
                          Closing Date).

                  (ii)    Any Claims relating to investigation or remediation of
                          any Environmental Condition on or at the Properties,
                          Environmental Conditions being addressed in Sections
                          8.4, 8.5 and 8.6.

Where an enforcement proceeding or penalty relates to violations of
Environmental Laws committed by both Seller before the Closing Date and Buyer
after the Closing Date, the costs of defense of any such proceeding and any
penalty shall be apportioned between the parties according to the number,
magnitude and seriousness of the violations committed by each (considering,
among other factors, the manner in which the regulatory agency or adjudicating
forum calculated the penalty imposed).  (For example, if in a proceeding
involving exceedances of air emission limits, a daily penalty of $1000 per day
was assessed for a violation that occurred on each of the 6 days prior to
Closing, and the 4 days after Closing, Seller would be responsible for $6000 of
the penalty, and Buyer would be responsible for $4000 of the penalty.  If,
however, the agency calculated the seriousness of the penalty as being $100 per
day for the 6 days of violations that occurred before Closing, and $1000 a day
for the 4 days of violations that occurred after Closing, Seller would be
responsible for $600, and Buyer would be responsible for $4000.)

                                  employees, agents and contractors access to,
                                  and reasonable accommodation at, the
                                  Jacksonville, Arkansas Business Site for such
                                  purpose.  The parties shall consult with each
                                  other to determine a mutually convenient time
                                  or times during which such access and

                          (C)     Buyer shall indemnify, defend, save and hold
                                  harmless Seller Indemnitees from and against

                                  for Seller's personnel and any contractors,
                                  consultants or other persons involved in the
                                  Modifications and will provide any necessary
                                  and relevant health and safety information to
                                  such persons.  However, Seller shall be
                                  responsible for ensuring that its personnel,

                                  contractors, and consultants are trained in
                                  relevant safety procedures and follow Buyer's
                                  safety rules and regulations.

                          (D)     Seller warrants to Buyer that upon completion
                                  of the planned Modifications, the
                                  Jacksonville Incinerator will be capable of
                                  performing reliably when handling daily
                                  volumes of liquid phase and vapor phase
                                  throughput equal to the daily throughput rate
                                  experienced by the Seller in 1994 (the "1994
                                  DAILY THROUGHPUT RATES").  For purposes of
                                  this warranty, the Jacksonville Incinerator
                                  shall be deemed to perform reliably if, when
                                  operated in compliance with the incinerator's
                                  operating instructions and good engineering
                                  practice, it is capable of incinerating
                                  liquid phase and vapor phase wastes from the
                                  polyester resin manufacturing process in
                                  volumes not exceeding the respective 1994
                                  Daily Throughput Rates, and of producing air
                                  emissions in compliance with Air Operating
                                  Permit No. 821-AR-1 in effect as of the
                                  Closing Date, with no more incinerator bypass
                                  operating time than allowed in Air Operating
                                  Permit No. 821-AR-1 (including the
                                  cross-referenced portions of the application

                                  such Air Operating Permit relating to bypass
                                  operating times).  Upon completion of the
                                  Modifications, Seller shall have the right to
                                  conduct a test of the Jacksonville Incinerator
                                  to measure its capability of complying with
                                  these criteria.  Such test shall be performed
                                  by an independent consultant, and Buyer shall
                                  have the right to observe the test.  In the
                                  event that such test (or any subsequent test)
                                  performed by the independent consultant, in
                                  which the incinerator is operated over a
                                  period of three (3) consecutive days in
                                  compliance with the incinerator's operating
                                  instructions and good engineering practice,
                                  indicates compliance with these criteria,
                                  Seller shall be deemed to have satisfied all
                                  of its obligations under the warranty set
                                  forth in this clause (D) and shall have no
                                  further liability to Buyer under Section
                                  8.3(f)(i).  In the event such test indicates
                                  non-compliance with these criteria, Seller
                                  shall have the right to make such further
                                  adjustments and modifications and to conduct
                                  such further tests as Seller shall deem
                                  necessary and appropriate.

                          (E)     Seller makes no warranty in Section
                                  8.3(f)(i)(D) with respect to the performance
                                  of the Jacksonville Incinerator at daily
                                  throughput rates of either liquid phase or
                                  vapor phase liquids that exceed the 1994
                                  Daily Throughput Rates.  The warranty set
                                  forth in Section 8.3(f)(i)(D) shall be void
                                  and of no further effect if (i) Buyer
                                  operates the Jacksonville Incinerator with
                                  inputs of liquid phase or vapor phase wastes
                                  in volumes greater than the respective 1994
                                  Daily Throughput Rates; or (ii) Buyer
                                  operates the Jacksonville Incinerator in a
                                  manner that does not comply with the
                                  incinerator's operating instructions and good
                                  engineering practice.

                   (ii)   All those pre-Closing environmental compliance issues
                          identified by Buyer in its due diligence investigation
                          are set forth in the Buyer Environmental Report (as
                          defined in Section 2.13).  Except as set forth in
                          Sections 8.3(d) and (e), under no circumstance shall
                          Seller be liable to Buyer in any respect whatsoever,
                          directly or indirectly, in connection with any of the
                          matters referred to in the Buyer Environmental Report
                          or any other pre-Closing instance of non-compliance

                          with applicable environmental laws, whether known or
                          unknown, and Buyer hereby releases Seller from any and
                          all liability in connection with all such matters.
                          Buyer acknowledges that it has negotiated a reduction
                          in the Purchase Price as full and sufficient
                          consideration for the foregoing release.

         (g)       TITLE V PERMIT.  Prior to Closing, Seller had commenced
preparation of the Title V air permit application for Bartow, Florida which is
due November 15, 1995.  As of the Closing, Buyer shall take over and complete
the preparation of the application and Buyer shall assume Seller's unaccrued
obligations under its contract with the consultant engaged to prepare the
application.

         (h)       DISCLAIMER OF LIABILITY.  No provision of this Agreement or
any of the Ancillary Documents (including any indemnification or cost-sharing
arrangement between Seller and Buyer) shall constitute an admission of
liability by either Buyer or Seller as to Claims made by third parties with
respect to Environmental Conditions or compliance with Environmental Laws.

         (i)       COOPERATION REGARDING CLAIMS AGAINST OTHER RESPONSIBLE
PARTIES.  Notwithstanding any indemnification or cost-sharing arrangement
between Buyer and Seller, both parties agree to cooperate with each other in
pursuing any claims that may be made

against other parties (including predecessor owners or operators of the
Properties) who may be responsible for Environmental Conditions or other
liabilities, and in pursuing any claims that may be pursued against insurers
who may have provided insurance coverage against such claims, liabilities,
losses, occurrences, incidents, or events, in accordance with the following
arrangements:

                   (i)    For matters on which Seller has an obligation to
                          defend:

                          (A)     Buyer shall, without charge to Seller, provide
                                  access to Buyer's employees and records.

                                  appropriate, Seller may include Buyer's name
                                  on any complaint or other pleading asserting
                                  claims against other responsible parties, and
                                  on any complaint or other pleading asserting
                                  a claim against an insurer (other than a
                                  claim arising under an insurance policy
                                  issued to Buyer).

                          (C)     Seller and Buyer agree to consult with each
                                  other regarding the pursuit of any defenses
                                  or claims (under the terms of a joint defense

                                  will consider Buyer's comments regarding such
                                  proceedings, but Seller shall have the
                                  ultimate right, in its discretion, to render
                                  all decisions regarding the pursuit of such
                                  claims and defenses.

                          (D)     The legal fees and other costs incurred to
                                  assert such defenses or claims shall be borne
                                  by Seller.

                   (ii)   For matters on which Buyer has an obligation to
                          defend:

                          (A)     Seller shall, without charge to Buyer, provide

                                  or appropriate, Buyer may include Seller's
                                  name on any complaint or other pleading
                                  asserting claims against other responsible
                                  parties, and on any complaint or other
                                  pleading asserting a claim against an insurer

                                  Buyer will consider Seller's comments
                                  regarding such proceedings, but Buyer shall
                                  have the ultimate right, in its discretion,
                                  to render all decisions regarding the pursuit
                                  of such claims and defenses.

                          Conditions under Section 8.5(e)):

                          (A)     Buyer and Seller shall make available to each
                                  other, without charge, their respective

                          Representatives, unless the parties agree to extend
                          this period.  The Management Representatives may
                          request the assistance of an independent mediator if

                   (v)    FORMAL RESOLUTION PROCEDURES.  In the event that the

                          (A)     Where (prior to the initiation of arbitration
                                  under Section 8.3(k)(v)(C)) an action has
                                  been initiated in a court or similar

                                  liability of the respective parties, Buyer
                                  and Seller shall (unless they mutually agree
                                  otherwise) utilize the Court to adjudicate

                                  asserting Claims against only one of the
                                  parties (but for which the named party
                                  believes the other party has an obligation of
                                  indemnification or defense), the parties
                                  agree to submit any dispute between
                                  themselves to arbitration under Section
                                  8.3(k)(v)(C) unless they mutually agree to
                                  submit such matter to the Court; provided,
                                  however, if in such a Court proceeding the
                                  initially unnamed party is, as a result of
                                  subsequent pleadings by a third party, added
                                  as a named party, and the Court undertakes
                                  the adjudication of relative contribution
                                  liability of the respective parties prior to
                                  the conclusion of arbitration, Buyer and
                                  Seller shall (unless they otherwise agree)

                                  their respective claims to the Court, and the

                          (C)     Except as provided in Sections 8.3(k)(v)(A)
                                  and 8.3(k)(v)(B), the parties shall submit
                                  any claim to binding arbitration and any
                                  controversy or claim arising out of or

                                           Environmental Professional to serve
                                           as arbitrator; or, if the parties
                                           are unable to agree upon a single
                                           arbitrator, each of the parties
                                           shall appoint an Environmental
                                           Professional to serve as arbitrator,
                                           and the two individuals so named
                                           shall, within thirty (30) additional
                                           days, agree upon a third independent
                                           Environmental Professional (who

                                  (4)      DISCOVERY.  For a period of sixty
                                           (60) days following the appointment

                                           agree or the arbitrator(s) may
                                           direct), the parties shall have the
                                           right to engage in such discovery
                                           relevant to the matters in dispute
                                           as is allowed pursuant to the
                                           discovery rules of the Pennsylvania

                                  (5)      RESOLUTION.  The arbitrator(s) shall
                                           decide such disputes pursuant to the
                                           Commercial Arbitration Rules of the
                                           American Arbitration Association in
                                           force at the time of the
                                           arbitration.  The arbitrator(s)
                                           shall be required to make a final
                                           determination, not subject to
                                           appeal, within thirty (30) days from
                                           the receipt of such dispute by the
                                           arbitrator(s), and the parties shall
                                           be bound by the terms of such final
                                           determination.  Where three
                                           arbitrators are appointed, the
                                           decision may be rendered by a
                                           majority of the arbitrators.  The
                                           determination by the arbitrator(s)
                                           shall be made in writing

                                           and shall contain written findings of
                                           fact, and may be specifically
                                           enforced by a court of competent
                                           jurisdiction.  The arbitrator(s)
                                           shall determine a fair and equitable
                                           allocation of the reasonable expenses
                                           of the parties incurred in connection
                                           with the resolution of any dispute
                                           hereunder.  Each party shall bear its
                                           own attorney's fees, unless the
                                           arbitrator(s) shall determine that
                                           the nature of the action or defense
                                           of the losing party was frivolous, in
                                           which event the arbitrator shall
                                           determine a fair and equitable
                                           attorney's fee to be paid by the
                                           losing party to the prevailing party.

                                  (6)      INDEPENDENCE OF ARBITRATOR.  The
                                           arbitrator(s) shall retain
                                           independence of all parties to this
                                           Agreement, and neither party shall
                                           engage or attempt to engage the
                                           services of the arbitrator(s) for
                                           any other purposes without prior
                                           written notice to the other party.

         (l)       NATURE OF PRESUMPTIONS.  Where any provision provides for a
presumption to be used in determining responsibility for an





                                    - 109 -
<PAGE>   119
Environmental Condition, such presumption shall be a rebuttable presumption.
Such presumption shall place the burden of going forward and the burden of
persuasion upon the party against whom the presumption applies.  The
presumption may be overcome by a preponderance of the evidence to the contrary.

         (m)       INDEMNIFICATION/DEFENSE ARRANGEMENTS.  Where either party
agrees to indemnify and defend the other, the following shall apply:

                   (i)    the amount of any recovery by a Buyer Indemnitee or a
                          Seller Indemnitee, as the case may be, shall be net
                          of any foreign, federal, state and/or local income
                          tax benefits inuring to the Indemnified Party as a
                          result of the state of facts that entitled the
                          Indemnified Party to recover from the Indemnifying
                          Party.

                   (ii)   the Indemnifying Party shall be obligated to indemnify
                          the Indemnified Party only for those claims as to
                          which the Indemnified Party has given the Indemnifying
                          Party written notice as promptly as practicable, but
                          in any event no later than forty-five (45) days after
                          the Indemnified Party's discovery of the facts giving
                          rise to any such claim.  Any written notice delivered
                          pursuant to this clause (ii) shall set forth with
                          specificity

                          the basis of the claim and an estimate of the amount
                          thereof.

                   (iii)  the Indemnifying Party shall have the right to conduct
                          and control, through counsel of its choosing, any
                          third party claim, action or suit, and the
                          Indemnifying Party may compromise or settle the same.
                          The Indemnified Party shall be permitted to
                          participate in the defense of any such action or suit
                          through counsel chosen by it; provided that the fees
                          and expenses of such counsel shall be borne
                          exclusively by the Indemnified Party.

                   (iv)   With respect to any obligation of the Indemnifying
                          Party arising out of an order, directive, or mandate
                          of an environmental agency or other governmental body,
                          the parties agree that the Indemnifying Party shall
                          have the right to appeal the terms and conditions of
                          such order, directive or mandate, and may postpone
                          compliance with its terms pending final disposition of
                          the appeal (provided that the terms and conditions are
                          stayed by operation of law or action of the relevant
                          authority).  The Indemnified Party agrees to cooperate
                          with the Indemnifying Party to the extent necessary to
                          effectuate the right of appeal.  The Indemnifying
                          Party who exercises the





                                    - 111 -

                          option to appeal agrees to indemnify, defend, save and
                          hold harmless the Indemnified Party and its officers,
                          directors, employees, agents, successors and permitted
                          assigns from and against any liabilities or damages
                          (including penalties) arising as a consequence.

         8.4.      PROVISIONS RELATING TO NEVILLE ISLAND FACILITY.  The
provisions set forth in this Section 8.4 shall apply exclusively to the Neville

                          Seller, which approval will not be unreasonably
                          withheld (considering among other factors the need
                          for such modifications to maintain the efficient
                          operation of Buyer's business at Neville Island, the
                          need for such modifications to comply with applicable
                          regulatory or other requirements, and the impact of
                          the proposed modifications on the Retained Premises).
                          If such a project involves excavation of land

                          methods of Polyester or MA production involving the
                          introduction, use, or production of any chemical not
                          in use as of the Closing Date without written
                          notification to Seller identifying such new chemical.

                          undertake the production or distribution of any other
                          chemical products or other businesses or activities on
                          Buyer's Operating Space without the express prior
                          approval of Seller, which approval shall not be
                          unreasonably withheld.

                   (iv)   Buyer will not undertake any activity involving
                          excavation of the land under Buyer's Operating Space
                          without notice to Seller; and Buyer shall not
                          undertake any activity involving excavation of the
                          land under Buyer's Operating Space (other than
                          excavation Required by Law, or excavation required to
                          undertake in-kind replacement, maintenance or repair
                          of equipment or structures on or included in Buyer's
                          Operating Space) without the express prior approval of
                          Seller, which approval shall be in Seller's sole
                          discretion.

         (c)       MINIMIZATION OF EXCAVATION.  If Buyer undertakes any New
Construction or Expansion Project, any project involving the maintenance,
repair or in-kind replacement of any then existing equipment or structures on
or included in Buyer's Operating





                                    - 114 -

Space, or any project that is Required by Law, Buyer shall take all reasonable
steps in the design and implementation of such project to minimize the area of
soils to be excavated or disturbed.

         (d)       INDEMNIFICATION FOR BUYER VIOLATIONS.  Buyer agrees to
indemnify, defend, save and hold harmless Seller Indemnitees from and against
any Claims (including Business Interruption Costs) arising out of the alleged
violation of any applicable Environmental Law associated with the operation by
Buyer of the Polyester or MA businesses on Buyer's Operating Space or
associated with any other use or activities conducted by Buyer on Buyer's
Operating Space or the Access Easement Areas.  For purposes of this provision,
Claims includes Business Interruption Costs incurred by Seller as a result of
the revocation or suspension of any permit held by Seller, or the denial of any
permit or permit renewal to Seller, where Buyer's violation is the substantial
and proximate cause of such permit revocation, suspension or denial.

         (e)       INDEMNIFICATION FOR SELLER VIOLATIONS.  Seller agrees to
indemnify, defend, save and hold harmless Buyer Indemnitees from and against
any Claims (including Business Interruption Costs) arising out of the alleged
violation of any applicable Environmental Law associated with the operation by
Seller of its businesses on the Retained Premises or associated with any other
use or activities conducted by Seller on the Retained Premises,

including the Access Easement Areas.  For purposes of this provision, Claims
includes Business Interruption Costs incurred by Buyer as a result of the
revocation or suspension of any permit held by Buyer, or the denial of any
permit or permit renewal to Buyer, where Seller's violation is the substantial
and proximate cause of such permit revocation, suspension or denial.

         (f)       ENVIRONMENTAL CONDITIONS CAUSED BY BUYER RELEASES AND
ACTIVITIES.  Buyer shall be responsible for and agrees to indemnify, defend,
save and hold harmless Seller Indemnitees from and against any Claims relating
to Buyer Environmental Conditions.  Where a release of a Buyer Regulated
Substance affects soils such as to require remediation, Buyer shall be solely
responsible for the remediation of any such affected soils, irrespective of
whether such soils also contain other Regulated Substances not related to the
Buyer Regulated Substance; provided that Buyer shall not be responsible under
this Section 8.3(f) for the remediation of soils containing a Buyer Regulated
Substance in combination with an other Regulated Substance if the nature and
concentration of the Buyer Regulated Substance does not require remediation.

         (g)       ENVIRONMENTAL CONDITIONS CAUSED BY SELLER RELEASES AND
ACTIVITIES.  Seller shall be responsible for and agrees to indemnify, defend,
save and hold harmless Buyer Indemnitees from and against any Claims relating
to Environmental Conditions resulting from the release of any Regulated
Substances arising

from Seller's operation after Closing of its business upon the Retained
Premises, or arising from any other use or activities conducted after Closing
by Seller on the Retained Premises, including the Access Easement Areas
(collectively, an "ARISTECH ENVIRONMENTAL CONDITION").

         (h)       PROVISIONS RELATING TO CONDITION OF EQUIPMENT, RECORDKEEPING
AND INSPECTIONS.

                   (i)    Buyer acknowledges that, prior to the Closing Date,
                          it has had the right to inspect the exterior of all
                          equipment and to review past testing and maintenance
                          records relating to all equipment (including tanks
                          and pipelines) being acquired on the Operating
                          Easement Areas.

                   (ii)   Buyer shall maintain all material and waste handling,
                          storage, processing, treatment and control equipment
                          on Buyer's Operating Space in good condition, and
                          shall conduct periodic inspections and tests of such
                          equipment to the extent (i) Required by Law or (ii)
                          consistent with Seller's inspection and testing
                          practices for such equipment prior to the Closing
                          Date, whichever is more stringent.  Buyer shall keep
                          records of all such required inspections and tests.
                          Seller may at any time advise Buyer in writing if
                          Seller

<PAGE>   127
                          believes that a modification of inspection or testing
                          practices is indicated by then prevailing good
                          engineering and operating practices; however, Seller
                          shall be under no obligation to advise Buyer regarding
                          such practices, and Buyer shall be solely responsible
                          for the maintenance, inspection and testing of its
                          equipment on Buyer's Operating Space.

                   (iii)  Buyer will keep accurate records of Regulated
                          Substances used, stored, treated, disposed, discharged
                          or generated on Buyer's Operating Space.  Such records
                          shall include all Required Regulated Substance Records
                          and inventory records, production records, purchase
                          orders, change orders related to purchase orders, and
                          requisitions concerning Regulated Substances.

                   (iv)   Buyer will keep accurate records of, and promptly
                          notify Seller of, the Release to the Environment of
                          any Regulated Substance, whether or not such release
                          is reportable to governmental authorities.

                   (v)    Seller shall have the right at any time upon
                          reasonable notice to inspect any portion of Buyer's
                          Operating Space and any of the records referred to in
                          Sections 8.4(b)(ii) through (iv),

                          and to investigate any actual or suspected Release to
                          the Environment of a Regulated Substance.  In the
                          event of an exigent condition, involving an actual or
                          threatened Release to the Environment that poses, or
                          is reasonably anticipated to pose, a significant
                          threat of pollution to surface water, groundwater or
                          other environmental media, Seller shall have the right
                          of immediate access to Buyer's Operating Space.  In
                          conducting any such inspection or investigation,
                          Seller shall take all reasonable steps to avoid
                          interference with Buyer's operations on Buyer's
                          Operating Space.

                   (vi)   Seller and Buyer agree to coordinate any investigation
                          of an actual or suspected Release to the Environment.
                          If Buyer undertakes adequate sampling or testing in
                          response to an actual or suspected Release to the
                          Environment, Seller shall refrain from conducting
                          duplicative tests or sampling; provided that Seller
                          shall have a right (at its expense) to observe such
                          investigations and to obtain and analyze split
                          samples.

         (i)       PROVISION OF SELLER RECORDS.  Seller agrees to provide Buyer
with all Required Regulated Substance Records regarding Regulated Substances
used, stored, treated, disposed, discharged or generated on the Operating
Easement Areas by Seller prior to





                                    - 119 -
<PAGE>   129
the Closing Date, to the extent that such information is in Seller's
possession.

         (j)       PRE-CLOSING ENVIRONMENTAL CONDITIONS.  Seller agrees to
indemnify, defend, save and hold harmless Buyer Indemnitees from and against
any Claims relating to any Pre-Closing Environmental Conditions, subject to the
limitations and conditions in Sections 8.4(k) through 8.4(n) and Section
8.4(p)(v).

         (k)       RESPONSIBILITY FOR REMEDIATION TRIGGERED BY NEW CONSTRUCTION
AND EXPANSION.  If Buyer undertakes any Construction or Expansion Project on
Buyer's Operating Space (other than a project Required by Law), and such
Construction or Expansion Project results in disclosure of an Environmental
Condition on Buyer's Operating Space that requires remediation under applicable
Environmental Law:

                   (i)    Buyer shall be solely responsible for all costs of
                          remediating Project Affected Soils and all costs of
                          remediating any Buyer Environmental Condition;

                   (ii)   Buyer shall be responsible for Buyer's Percentage of
                          the costs of required remediation of any disclosed
                          Environmental Condition (other than a Buyer
                          Environmental Condition) within Buyer's

                          Operating Space that affects media other than Project
                          Affected Soils; and

                   (iii)  Seller shall be responsible for Seller's Percentage of
                          the costs of required remediation of any Environmental
                          Condition (other than Buyer Environmental Condition)
                          within Buyer's Operating Space that affects media
                          other than Project Affected Soils.

         (l)       RESPONSIBILITY FOR REMEDIATION TRIGGERED BY REPAIR,
REPLACEMENT OR PROJECTS REQUIRED BY LAW.  If Buyer undertakes any project
involving the repair, maintenance or in-kind replacement of any then existing
equipment or structures on or included in Buyer's Operating Space, or any
project that is Required by Law, and such project results in the disclosure of
an Environmental Condition that requires remediation under applicable
Environmental Law:

                   (i)    Buyer shall be responsible for the costs of required
                          remediation of Project Affected Soils and the costs
                          of required remediation of any Buyer Environmental
                          Condition; and

                   (ii)   Seller shall be responsible for the costs of required
                          remediation of any Environmental

                          Condition, other than a Buyer Environmental Condition
                          and other than Project Affected Soils.

         (m)       ALLOCATION WHERE LIABILITY FOR ENVIRONMENTAL CONDITIONS IS
SHARED.  Except as otherwise provided in Sections 8.4(f), 8.4(k) or 8.4(l) or
otherwise specifically provided in this Agreement, where (after the application
of the presumptions contained in Section 8.4(n)) it is determined that an
Environmental Condition that requires remediation is the result of a Buyer
Environmental Condition in combination with either a Pre-Closing Environmental
Condition or an Aristech Environmental Condition, liability for any Claims
associated with or arising from such Environmental Condition shall be allocated
equitably between Seller and Buyer, based on a consideration of (among others)
the following factors:

                   (i)    Whether, but for the Environmental Condition for
                          which one of the parties is solely responsible, an
                          obligation to investigate or remediate would have
                          arisen for the other party;

                   (ii)   The relative quantity, toxicity and area affected by
                          the Regulated Substances for which the respective
                          parties are responsible;

                   (iii)  The degree to which the Regulated Substance for which
                          a party is responsible affects the selection

                          of the remedy, the cost of the remedy, and the period
                          of time over which the remedy must be implemented; and

                   (iv)   Other relevant considerations.

         (n)       DETERMINATION OF PRE-CLOSING ENVIRONMENTAL CONDITIONS/BUYER
ENVIRONMENTAL CONDITIONS.

                   (i)    The parties agree that, prior to the conduct of an
                          Environmental Assessment (such as provided under
                          Section 8.4(p)), the following presumptions will be
                          used in the determination of whether an Environmental
                          Condition discovered at Buyer's Operating Space or
                          the Access Easement Areas is a Pre-Closing
                          Environmental Condition or a Buyer Environmental
                          Condition:

                          (A)     If the Environmental Condition involves a
                                  Regulated Substance that was not used,
                                  generated, or stored by Buyer, and is not a
                                  decomposition product of a substance used,
                                  generated, or stored by Buyer, it shall be
                                  presumed that the Environmental Condition is
                                  a Pre-Closing Environmental Condition.

<PAGE>   133
                          (B)     If the Environmental Condition involves a
                                  Regulated Substance that was used, generated,
                                  or stored by Buyer, or is a decomposition
                                  product of a substance used, generated, or
                                  stored by Buyer, and such Regulated Substance
                                  was not used, generated or stored by Seller,
                                  it shall be presumed that the Environmental
                                  Condition is a Buyer Environmental Condition.

                          (C)     If the Environmental Condition involves a
                                  Regulated Substance that was used, generated,
                                  or stored by both Seller and Buyer, or is a
                                  decomposition product of such a substance,
                                  then:

                                  (1)      in the absence of evidence that such
                                           Environmental Condition resulted
                                           from a release of the Regulated
                                           Substance by Buyer, the
                                           Environmental Condition shall be
                                           presumed to be a Pre-Closing
                                           Environmental Condition.

                                  (2)      if there is evidence that the
                                           Environmental Condition resulted
                                           from a release of a Regulated
                                           Substance by Buyer, the
                                           Environmental Condition shall

                                           be presumed to be a Buyer
                                           Environmental Condition.

                   (ii)   If an Environmental Assessment is conducted of Buyer's
                          Operating Space, the parties agree that the following
                          presumptions will be used in the determination of
                          whether an Environmental Condition discovered at
                          Buyer's Operating Space or the Access Easement Areas,
                          either in or after the Environmental Assessment, is a
                          Pre-Closing Environmental Condition or a Buyer
                          Environmental Condition:

                          (A)     If the Environmental Condition involves a
                                  Regulated Substance that was not used,
                                  generated, or stored by Buyer, and is not a
                                  decomposition product of a substance used,
                                  generated or stored by Buyer, it shall be
                                  presumed that the Environmental Condition is
                                  a Pre-Closing Environmental Condition.

                          (B)     If the Environmental Condition involves a
                                  Regulated Substance that was used, generated,
                                  or stored by Buyer, or is a decomposition
                                  product of a substance used, generated or
                                  stored by Buyer, and such Regulated Substance
                                  was not used, generated or stored by Seller,

                                  Condition is a Buyer Environmental Condition.

                          (C)     If the Environmental Condition involves a
                                  Regulated Substance that was used, generated,
                                  or stored by both Seller and Buyer, or is a
                                  decomposition product of such a substance, it
                                  shall be presumed that:

                                  (1)      the concentrations and areas

                                           Environmental Assessment involving
                                           the presence in soils of a Regulated
                                           Substance, or breakdown product
                                           thereof, at a higher concentration
                                           or in a different area than
                                           identified in the Environmental

                                           Condition.

                                  Where an Environmental Condition found after
                                  the completion of the Environmental
                                  Assessment involves the presence in
                                  groundwater of a Regulated Substance, or

                                  identified in the Environmental Assessment,
                                  no presumptions shall be made.

                   (iii)  The parties agree that, at all times, the following
                          presumptions will be used in the determination of
                          whether an Environmental Condition discovered at
                          Buyer's Operating Space or Easement Areas is a
                          Pre-Closing Environmental Condition or a Buyer

                          (A)     If an Environmental Condition relates to a
                                  Regulated Substance that Buyer has used,
                                  generated or stored, but where Buyer has
                                  failed to maintain accurate records with
                                  respect to the use and management of such
                                  substance as required under Section 8.4(h),
                                  it shall be presumed that the Environmental
                                  Condition is a Buyer Environmental Condition.

                          (B)     If an Environmental Condition is located in
                                  the vicinity of equipment that Buyer
                                  operated, and relates to a Regulated
                                  Substance used in relation to such equipment,
                                  and Buyer has failed to inspect and test such
                                  equipment as required under Section 8.4(h),
                                  it shall be presumed that the Environmental
                                  Condition is a Buyer Environmental Condition.

                                  of equipment or structures on or included in
                                  Buyer's Operating Space.

                          (B)     Seller shall be the Lead Party with respect
                                  to any Environmental Condition on Buyer's
                                  Operating Space other than a Buyer
                                  Environmental Condition or an Environmental
                                  Study undertaken with respect to maintenance,
                                  monitoring, repair or replacement of
                                  equipment or structures on or included in
                                  Buyer's Operating Space.

                   (ii)   ENVIRONMENTAL STUDIES.  Buyer shall not undertake any
                          environmental study, testing or sampling of soils or
                          groundwater under Buyer's Operating Space
                          ("ENVIRONMENTAL STUDY") without notice to Seller.

                          (A)     No such Environmental Study shall be
                                  undertaken by Buyer (unless such study is
                                  Required by Law) without the approval of
                                  Seller.

                          (B)     Where such an Environmental Study is ordered
                                  or otherwise directed by a governmental
                                  agency, Buyer shall provide Seller with
                                  prompt notice of such a requirement, and

<PAGE>   139
                                  Seller shall have the right to appeal such
                                  action.

                          (C)     If Buyer believes an Environmental Study is
                                  otherwise Required by Law, Buyer shall
                                  provide Seller with written notice, stating
                                  the reasons why Buyer believes the study is
                                  Required by Law.  If Seller believes to the
                                  contrary, Seller shall so notify Buyer within
                                  fourteen (14) days of receiving the notice
                                  from Buyer, stating the reasons Seller
                                  believes that the Environmental Study is not
                                  Required by Law.

                          (D)     Where such an Environmental Study is
                                  requested by a governmental agency, but not
                                  Required by Law, Buyer shall provide prompt
                                  notice of such request, and the parties shall
                                  consult regarding the appropriate response to
                                  such request; provided that no such
                                  Environmental Study shall be undertaken
                                  without the approval of Seller.

                          (E)     If Buyer undertakes an Environmental Study
                                  that is not Required by Law without Seller's
                                  approval, Buyer shall be solely responsible
                                  for any Environmental Conditions disclosed by

                                  such study, and all indemnifications by Seller
                                  with respect to such Environmental Conditions
                                  shall be void.

                          (F)     Whether or not a study is Required by Law,
                                  except for a Buyer Environmental Condition or
                                  the Environmental Studies related to the
                                  maintenance, monitoring, repair or
                                  replacement of a structure on Buyer's
                                  Operating Space, Seller shall have the option
                                  (exercisable in Seller's sole discretion) to
                                  be Lead Party in any such Environmental
                                  Study.

         (p)       OPTION TO CONDUCT ASSESSMENT/REMEDIATION PLAN.

                   (i)    Seller has the option, at any time (whether or not
                          Required by Law) to conduct an Environmental
                          Assessment of Buyer's Operating Space.

                   (ii)   On the basis of such Environmental Assessment, Seller
                          may (whether or not Required by Law) prepare a
                          remediation plan to address any Environmental
                          Condition that requires remediation under applicable
                          Environmental Law.

                   (iii)  The parties agree that any remediation plan shall be
                          designed to meet any environmental cleanup standards
                          established by statute, duly-adopted regulations, or
                          policies that have the force of law ("REGULATORY
                          REMEDIATION STANDARDS").  Where remediation is
                          required under then current Environmental Laws, but
                          definitive Regulatory Remediation Standards have not
                          been adopted, the remediation plan shall be based on
                          an Appropriate and Reasonable Criteria.  The parties
                          agree that, unless otherwise mandated by applicable
                          governmental agencies having jurisdiction over the
                          Environmental Condition, the remediation plan to be
                          proposed and implemented shall be that alternative for
                          meeting such Regulatory Remediation Standards or
                          Appropriate and Reasonable Criteria that: (i) has the
                          least cost (considering the present discounted value
                          of both capital cost and operating and maintenance
                          costs), and (ii) does not unreasonably interfere with
                          the operations on Buyer's Operating Space.

                   (iv)   Seller shall submit any proposed remediation plan to
                          the Pennsylvania Department of Environmental Resources
                          ("DER") or any other appropriate regulatory authority.
                          Upon approval of the remediation plan, Seller shall
                          implement the plan

                          (subject to reimbursement by Buyer for any costs
                          associated with remediation of Buyer Environmental
                          Conditions).

                   (v)    Upon completion of the work prescribed under the
                          approved remediation plan, Seller shall be relieved
                          of any further liability for Pre-Closing
                          Environmental Conditions at Buyer's Operating Space
                          to the extent that such Pre-Closing Environmental
                          Conditions were located in areas evaluated as part of
                          the Environmental Assessment submitted to the DER or
                          other appropriate regulatory authority and the
                          Pre-Closing Environmental Conditions involve
                          substances that were analyzed for (either directly or
                          through surrogate parameters) as part of the
                          Environmental Assessment ("ASSESSED ENVIRONMENTAL
                          CONDITIONS").  (As an example, if the Environmental
                          Assessment evaluated samples for total petroleum
                          hydrocarbons, it would be deemed to have evaluated
                          constituent petroleum hydrocarbons.)  Buyer shall
                          release any further claims against Seller relating to
                          such Assessed Environmental Conditions at Buyer's
                          Operating Space (including Pre-Closing Environmental
                          Conditions, whether known or unknown), and Buyer
                          shall indemnify, defend, save and hold harmless

                          completion of the approved remediation plan.

         (q)       ACCESS FOR REMEDIATION.  Buyer acknowledges that
investigation and remediation of Environmental Conditions may include testing,
monitoring and other activities on Buyer's Operating Space related to the
Environmental Conditions.  Access for such activities shall be provided under
the following arrangements:

                   (i)    Seller and Buyer shall consult in efforts to
                          coordinate any such activities with operations on
                          Buyer's Operating Space, and Seller shall take all
                          reasonable steps to minimize interference with
                          Buyer's operations.

                   (ii)   Seller shall have the right to enter Buyer's Operating
                          Space at any time and from time to time for the
                          purpose of conducting any activity in connection with
                          investigation, remediation and monitoring of
                          Environmental Conditions, whether pursuant to a
                          remediation plan or otherwise.  (This provision shall
                          supersede any contrary or inconsistent provision in
                          any agreement or other

                          instrument granting Buyer rights in or otherwise
                          relating to Buyer's Operating Space.)

                   (iii)  Seller agrees that it will not make any change in
                          Buyer's Operating Space or use Buyer's Operating Space
                          for any purpose not necessary and appropriate to the
                          performance of the investigation, remediation and
                          monitoring of Environmental Conditions.

                   (iv)   During any investigation, remediation, or monitoring
                          work, Seller agrees to comply with all applicable
                          laws, regulations, rules or permits pertaining to
                          Buyer's Operating Space, including environmental,
                          occupational health and safety, and other health and
                          safety laws.  Seller agrees to indemnify, defend, save
                          and hold harmless Buyer Indemnitees from and against
                          any Claims arising from failure to comply with such
                          laws.

                   (v)    Upon completion of any work required for
                          investigation, remediation, or monitoring of
                          Environmental Conditions, Seller shall promptly
                          restore any structures, pavement, or other parts of
                          Buyer's Operating Space to substantially the
                          condition they were in prior to engaging in such
                          work.

                   (vi)   Where Seller voluntarily undertakes an Environmental
                          Assessment or remediation plan, other than an
                          Environmental Assessment or remediation plan that is
                          Required by Law or that is undertaken in connection
                          with a project Required by Law, Seller shall be
                          responsible for, and agrees to indemnify Buyer from
                          and against, any Business Interruption Costs incurred
                          by Buyer as a proximate cause of such work. Where an
                          Environmental Assessment or remediation plan is
                          Required by Law, Seller shall not be liable for any
                          Business Interruption Costs.

                   (vii)  Except as provided in Sections 8.4(q)(iv) through
                          8.4(q)(vi), and except for the willful or negligent
                          acts or omissions of Seller, Seller shall not be
                          liable for any loss or damage of any kind caused by
                          Seller's activities on Buyer's Operating Space in
                          connection with such investigation, remediation and
                          monitoring activities.

         (r)       STORMWATER SYSTEM LIABILITIES.

                   (i)    The parties understand that they will be sharing a
                          common stormwater sewer system and outfall, that will
                          receive and discharge stormwater associated

                          with industrial activities generated at both Buyer's
                          facilities on Buyer's Operating Space, and Seller's
                          facilities on the Retained Premises.

                   (ii)   In the event of a discharge of stormwater that
                          contains pollutants in excess of applicable effluent
                          limitations, or that otherwise violates any applicable
                          regulation, permit term or condition, the parties
                          agree to cooperate in the investigation of the source
                          of such pollutants or the cause of such
                          non-compliance.

                          (A)     If the pollutant is a chemical that is used,
                                  generated, or stored by Buyer in connection
                                  with the Polyester or MA operations or other
                                  Buyer operations at Buyer's Operating Space,
                                  but is not used, generated, or stored by
                                  Seller in connection with the operations on
                                  the Retained Premises, it will be presumed
                                  that Buyer is responsible.

                          (B)     If the pollutant is a chemical that is used,
                                  generated or stored by Seller in connection
                                  with the operations on the Retained Premises,
                                  but is not used, generated or stored by Buyer
                                  in connection with the Polyester, MA or other





                                    - 137 -

                                  Buyer operations, it will be presumed that
                                  Seller is responsible.

                          (C)     If the pollutant is a chemical that is used,
                                  generated, or stored by both Seller and
                                  Buyer, no presumptions shall be made
                                  regarding responsibility.

                          (D)     Either party shall have the opportunity to
                                  demonstrate that an effluent limit exceedance
                                  or other violation is a result of
                                  infiltration from contaminated groundwater,
                                  in which event responsibility for the
                                  violation shall be apportioned in accordance
                                  with the allocation of liability for the
                                  Environmental Conditions giving rise to such
                                  contamination.

                   (iii)  Each of Buyer and Seller, to the extent it is
                          responsible for the discharge of the pollutant or the
                          area that was the source of the pollutant causing the
                          non-compliance shall indemnify, defend and hold
                          harmless Seller Indemnitees or Buyer Indemnitees,
                          respectively, for all costs, damages, claims,
                          liabilities and penalties arising or resulting from
                          such non-compliance.

                   (iv)   If a determination cannot be made regarding the source
                          of the pollutant causing the non-compliance, the
                          parties shall proportionately share any costs relating
                          to the non-compliance event based on Buyer's
                          Percentage and Seller's Percentage.

         (s)       Effect of Services Agreement.  The provisions of the
Services Agreement, including without limitation the requirement that Seller's
employees provide certain maintenance and other services for Buyer, shall have
no effect on the obligations and rights of the parties as set forth in this
Section 8.4.  To the extent that the provisions of this Section 8.4 are
inconsistent with the provisions of the Services Agreement, the provisions of
this Section 8.4 shall control.

         8.5.      PROVISIONS RELATING TO OTHER PRODUCTION FACILITIES.  The
provisions set forth in this Section 8.5 shall apply exclusively to the Bartow,
Florida, Jacksonville, Arkansas and Colton, California Business Sites (the
"OTHER PRODUCTION FACILITIES").

         (a)       POST-CLOSING VIOLATIONS.  Buyer agrees to indemnify, defend,
save and hold harmless Seller Indemnitees from and against any Claims arising
out of the alleged violation of any applicable Environmental Law associated
with the operation by Buyer of the Other Production Facilities or arising from
any

other use or activities conducted by Buyer on the Other Production Facilities.

         (b)       ENVIRONMENTAL CONDITIONS CAUSED BY BUYER RELEASES AND
ACTIVITIES.  Buyer shall be responsible for and agrees to indemnify, defend,
save and hold harmless Seller Indemnitees from and against any Claims relating
to Buyer Environmental Conditions at the Other Production Facilities.  Where a
release of a Buyer Regulated Substance affects soils such as to require
remediation, Buyer shall be solely responsible for the remediation of any such
affected soils, irrespective of whether such soils also contain other Regulated
Substances not related to the Buyer Regulated Substance; provided that Buyer
shall not be responsible under this Section 8.5(b) for the remediation of soils
containing a Buyer Regulated Substance in combination with an other Regulated
Substance if the nature and concentration of the Buyer Regulated Substance does
not require remediation.

         (c)       PROVISIONS RELATING TO CONDITION OF EQUIPMENT AND
RECORDKEEPING.

                   (i)    Buyer acknowledges that, prior to Closing it has had

                          Seller may at any time advise Buyer in writing if
                          Seller believes that a modification of inspection or
                          testing practices is indicated by then prevailing good
                          engineering and operating practices; however, Seller
                          shall be under no obligation to advise Buyer regarding
                          such practices, and Buyer shall be solely responsible
                          for the maintenance, inspection and testing of its
                          equipment at the Other Production Facilities.

                          to governmental authorities.

                   (v)    Seller shall have the right at any time upon
                          reasonable notice to inspect any of the records

                                  Property.

                                  Contamination in and resulting from the
                                  former waste pond identified as a Solid Waste
                                  Management Unit in a document entitled
                                  "Information Regarding Potential Releases
                                  from Solid Waste Management Units" for

                   (ii)   With respect to the following Environmental
                          Conditions, Seller shall be liable for all costs
                          relating to closure of the listed units until such
                          closure is approved by the environmental agency having
                          jurisdiction under RCRA.  After such closure has been
                          approved, Seller shall be responsible for any
                          additional assessments or investigations of the
                          affected units and areas (including RCRA facility
                          investigations) required as a result of such unit

                          subject to RCRA corrective action.  Any Environmental
                          Condition found as a result of such post-closure
                          investigation shall be treated as an Other
                          Environmental Condition, and any liability associated
                          with required remediation of, or Claims relating to,
                          such other Environmental Condition shall be allocated
                          between Seller and Buyer in accordance with Section

                          year 21 and thereafter) with respect to Environmental
                          Conditions referred to in Section 8.2(e)(iii), and
                          (B) the 24th anniversary following the Closing Date
                          (that is, in year 25 and thereafter with respect to
                          Environmental Conditions referred to in Section
                          8.2(e)(ii), Buyer shall indemnify, defend, save and
                          hold harmless Seller Indemnitees from and against any
                          Claims relating to Environmental Conditions at the
                          Other Production Facilities (other than for those
                          Identified Environmental Conditions for which Seller
                          retains continuing liability under Section 8.5(d)).

         (f)     SPECIAL PRESUMPTIONS.  The parties agree that, at all times,
the following presumptions shall be used in the determination of whether an
Environmental Condition discovered at an Other Production Facility Property is
a Buyer Environmental Condition:

                          (i)  If an Environmental Condition relates to a
                          Regulated Substance that Buyer has used, generated





                                    - 155 -
<PAGE>   165
                          or stored, but where Buyer has failed to maintain
                          accurate records with respect to the use and
                          management of such substance as required under Section
                          8.5(c), it shall be presumed that the Environmental
                          Condition is a Buyer Environmental Condition.

                          (ii)  If an Environmental Condition is located in the
                          vicinity of equipment that Buyer operated, and
                          relates to a Regulated Substance used in relation to
                          such equipment, and Buyer has failed to inspect and
                          test such equipment as required under Section 8.5(c),
                          it shall be presumed that the Environmental Condition
                          is a Buyer Environmental Condition.

         (g)     ALLOCATION WHERE LIABILITY FOR ENVIRONMENTAL CONDITIONS IS
SHARED.  Except as otherwise provided in Section 8.5(b) or otherwise
specifically provided in this Agreement, where (after the application of the
presumptions contained in Section 8.5(f)) it is determined that an
Environmental Condition that requires remediation is the result of a Buyer
Environmental Condition in combination with either an Identified Environmental
Condition or an Other Environmental Condition, liability for any Claims
associated with or arising from such Environmental Condition shall be allocated
equitably between Seller and Buyer, based on a consideration of (among others)
the following factors:


                                    - 156 -
<PAGE>   166
                   (i)    Whether, but for the Environmental Condition for
                          which one of the Parties is solely responsible, an
                          obligation to investigate or remediate would have
                          arisen for the other party;

                   (ii)   The relative quantity, toxicity and area affected by
                          the Regulated Substances for which the respective
                          parties are responsible;

                   (iii)  The degree to which the Regulated Substance for which
                          a party is responsible affects the selection of the
                          remedy, the cost of the remedy, and the period of
                          time over which the remedy must be implemented; and

                   (iv)   Other relevant considerations.

         (h)     CONTACTS WITH AGENCIES/DESIGNATION OF LEAD PARTIES.

                   (i)    Buyer shall be the Lead Party with respect to any
                          Buyer Environmental Condition, and with respect to
                          any Other Environmental Condition that is discovered
                          and confirmed in and after (A) Year 11 with respect
                          to those Environmental Conditions referred to in
                          Section 8.5(e)(iii), and (B) Year 15 with respect to
                          those Environmental Conditions referred to in Section
                          8.5(e)(ii).

                   (ii)   Seller shall be the Lead Party with respect to any
                          Identified Environmental Condition.

                   (iii)  At its option and upon written notification to Buyer,
                          Seller shall be the Lead Party with respect to any
                          Other Environmental Condition that is discovered and
                          confirmed prior to Year 11 or Year 15, as applicable.

         (i)     OPTION TO CONDUCT ASSESSMENT/REMEDIATION PLAN.

                   (i)    For the first ten (10) years after Closing, Seller
                          has the option, at any time (whether or not Required
                          by Law) to conduct an Environmental Assessment of any
                          Other Production Facility.

                   (ii)   If an Environmental Assessment is conducted at an
                          Other Production Facility, the parties agree that the
                          following presumptions will be used in the
                          determination of whether an Environmental Condition
                          discovered at the Other Production Facility, either
                          in or after the Environmental Assessment, is an Other
                          Environmental Condition or a Buyer Environmental
                          Condition:

                          (A)     If the Environmental Condition involves a
                                  Regulated Substance that was not used,

                                  decomposition product of a substance used,
                                  generated or stored by Buyer, it shall be
                                  presumed that the Environmental Condition is
                                  an Other Environmental Condition.

                          (B)     If the Environmental Condition involves a
                                  Regulated Substance that was used, generated,
                                  or stored by Buyer, or is a decomposition
                                  product of a substance used, generated or
                                  stored by Buyer, and such Regulated Substance
                                  was not used, generated or stored by Seller,
                                  it shall be presumed that the Environmental
                                  Condition is a Buyer Environmental Condition.

                          (C)     If the Environmental Condition involves a
                                  Regulated Substance that was used, generated,
                                  or stored by both Seller and Buyer, or is a
                                  decomposition product of such a substance, it
                                  shall be presumed that:

                                  (1)      the concentrations and areas
                                           affected by the Regulated Substance
                                           as identified in the Environmental

                                           not the decomposition product of a
                                           substance identified in the

                                  decomposition product thereof, in higher
                                  concentrations or in different areas than
                                  identified in the Environmental Assessment, no
                                  presumptions shall be made.

                   (iii)  On the basis of such Environmental Assessment, Seller
                          may (whether or not Required by Law) prepare a
                          remediation plan to address any Environmental
                          Condition that requires remediation under applicable
                          Environmental Law.

                   (iv)   The parties agree that any remediation plan
                          (including any remediation plan to address an
                          Identified Environmental Condition) shall be designed
                          to meet Regulatory Remediation Standards.  Where
                          remediation is required under then current
                          Environmental Laws, but definitive Regulatory
                          Remediation Standards have not been adopted, the
                          remediation plan shall be based on Appropriate and
                          Reasonable Criteria.  The parties agree that, unless
                          otherwise mandated by applicable governmental
                          agencies having jurisdiction over the Environmental
                          Condition, the remediation plan to be proposed and
                          implemented shall be that alternative for meeting
                          such Regulatory Remediation Standards or Appropriate
                          and Reasonable Criteria that: (i) has the least cost

<PAGE>   171
                          (considering the present discounted value of both
                          capital cost and operating and maintenance costs), and
                          (ii) does not unreasonably interfere with the
                          operations on the Other Production Facility.

                   (v)    Seller shall submit any proposed remediation plan to
                          the applicable state environmental agency.  Upon
                          approval of the remediation plan, Seller shall
                          implement the plan (subject to reimbursement by Buyer
                          for any costs associated with remediation of Buyer
                          Environmental Conditions and Buyer's share of costs
                          for Other Environmental Conditions).

                   (vi)   Upon completion of the work at an Other Production
                          Facility prescribed under the approved remediation
                          plan, Seller shall be relieved of any further
                          liability for Environmental Conditions at the Other
                          Production Facility to the extent that such
                          Environmental Conditions are Assessed Environmental
                          Conditions.  (As an example, if the Environmental
                          Assessment evaluated samples for total petroleum
                          hydrocarbons, it would be deemed to have evaluated
                          constituent petroleum hydrocarbons.)   Buyer shall
                          release any further claims against Seller relating to
                          such Assessed Environmental Conditions at the
                          applicable Other

                          Production Facility (whether known or unknown), and
                          Buyer shall indemnify, defend, save and hold harmless
                          Seller Indemnitees against any Claims related to
                          Assessed Environmental Conditions discovered at such
                          Other Production Facility after the completion of the
                          approved remediation plan.

         (j)     ACCESS FOR INVESTIGATION AND REMEDIATION.  Buyer acknowledges
that investigation and remediation of Environmental Conditions at the Other
Production Facilities may include testing, monitoring and other activities at
the Other Production Facilities related to the Environmental Conditions.  Buyer
shall provide Seller and Seller's consultants, contractors and agents with
access to, and reasonable accommodation at, the Other Production Facilities for
such purposes under the following arrangements:

                   (i)    Seller and Buyer will agree to consult in efforts to
                          coordinate any such activities with operations at the
                          Other Production Facilities, in order to take all
                          reasonable steps to minimize interference with
                          Buyer's operations.

                   (ii)   Anything in this Agreement to the contrary
                          notwithstanding, Seller shall have the right to enter
                          the Other Production Facilities at any time and from
                          time to time for the purpose of


                                    - 163 -
<PAGE>   173
                          conducting any activity in connection with
                          investigation, remediation and monitoring of
                          Environmental Conditions, whether pursuant to a
                          remediation plan or otherwise.

                   (iii)  Seller agrees that it will not make any change in the
                          Other Production Facilities or use the Other
                          Production Facilities for any purpose not necessary
                          and appropriate to the performance of the
                          investigation, remediation and monitoring of
                          Environmental Conditions.

                   (iv)   During any investigation, remediation, or monitoring
                          work, Seller agrees to comply with all applicable
                          laws, regulations, rules or permits pertaining to the
                          applicable Other Production Facility, including
                          environmental, occupational health and safety, and
                          other health and safety laws.  Seller agrees to
                          indemnify, defend, save and hold harmless Buyer
                          Indemnitees from and against any Claims arising from
                          failure to comply with such laws.

                   (v)    Upon completion of any work required for
                          investigation, remediation, or monitoring of
                          Environmental Conditions, Seller shall promptly
                          restore any structures, pavement, or other parts





                                    - 164 -

                          of the Other Production Facilities to substantially
                          the condition they were in prior to engaging in such
                          work.

                   (vi)   Where Seller voluntarily undertakes an Environmental
                          Assessment or remediation plan, other than an
                          Environmental Assessment or remediation plan that is
                          Required by Law, Seller shall be responsible for, and
                          agrees to indemnify Buyer from and against, any
                          Business Interruption Costs incurred by Buyer as a
                          proximate cause of such work.  Where an Environmental
                          Assessment or Remediation Plan is Required by Law,
                          Seller shall not be liable for any Business
                          Interruption Costs.

                   (vii)  Except as provided in Sections 8.5(j)(iv) through
                          8.5(j)(vi), and except for the willful or negligent
                          acts or omissions of Seller, Seller shall not be
                          liable for any loss or damage of any kind caused by
                          Seller's activities at the Other Production
                          Facilities in connection with such investigation,
                          remediation and monitoring activities.

         8.6.    PROVISIONS RELATING TO DISTRIBUTION FACILITIES.  The
provisions set forth in this Section 8.6 shall apply exclusively to the
Business Sites other than the Neville Island Facility and





                                    - 165 -
<PAGE>   175
the Other Production Facilities (the "DISTRIBUTION FACILITIES").

         (a)     POST-CLOSING VIOLATIONS.  Buyer agrees to indemnify, defend,
save and hold harmless Seller Indemnitees from and against any Claims arising
out of the alleged violation of any applicable Environmental Law associated
with the operation by Buyer of the Distribution Facilities or arising from any
other use or activities conducted by Buyer at the Distribution Facilities.

         (b)     ENVIRONMENTAL CONDITIONS CAUSED BY BUYER RELEASES AND
ACTIVITIES.  Buyer shall be responsible for and agrees to indemnify, defend,
save and hold harmless Seller Indemnitees from and against any Claims relating
to Buyer Environmental Conditions at the Distribution Facilities.  Where a
release of any Buyer Regulated Substance affects soils such as to require
remediation, Buyer shall be solely responsible for the remediation of any such
affected soils, irrespective of whether such soils also contain other Regulated
Substances not related to the Buyer Environmental Condition.

         (c)     ANKENY DISTRIBUTION FACILITY.  With respect to Pre-Closing
Environmental Conditions at the Ankeny, Iowa Distribution Facility arising from
the former operations of the Albaugh Chemical Company at the Property, to the
extent that Buyer is not indemnified by virtue of the indemnification to the
lessee of such Distribution Facility from the lessor thereof, Seller shall


                                    - 166 -
<PAGE>   176
be responsible for (and indemnify, defend, save and hold harmless Buyer
Indemnitees from and against) a proportionate share of the non-indemnified
costs incurred by Buyer.  The proportionate share shall be determined based on
the period of time Seller and Buyer respectively have been in possession under
the current lease.  This indemnity is subject to the following terms and
conditions:

                   (i)    If Buyer renews or renegotiates the current lease,
                          Seller's obligation under this Section 8.6(c) shall
                          terminate upon the expiration date of the current
                          term of the lease.

                   (ii)   If Buyer does not renew or renegotiate the current
                          lease, Seller's obligation under this Section 8.6(c)
                          shall not expire.

         (d)     OTHER DISTRIBUTION FACILITIES.  Seller agrees to indemnify,
defend, save and hold harmless Buyer Indemnitees from and against any Claims
relating to any Pre-Closing Environmental Conditions at the Distribution
Facilities (except for the Ankeny, Iowa Distribution Facility, which is
provided for in Section 8.6(c)).  Seller's obligation under this Section 8.6(d)
shall terminate upon (i) the date on which Buyer vacates the premises of such
Distribution Facility, or (ii) the expiration date of the current term of the
lease for any such Distribution Facility, whichever is earlier.

<PAGE>   177
         (e)     ALLOCATION WHERE LIABILITY FOR ENVIRONMENTAL CONDITIONS IS
SHARED.  Except as provided in Section 8.6(b), where an Environmental Condition
that requires remediation is the result of a Buyer Environmental Condition in
combination with a Pre-Closing Environmental Condition, liability for any
Claims associated with or arising from such Environmental Condition shall be
allocated equitably between Seller and Buyer, based on a consideration of
(among others) the following factors:

                   (i)    Whether, but for the Environmental Condition for
                          which one of the parties is solely responsible, an
                          obligation to investigate or remediate would have
                          arisen for the other party;

                   (ii)   The relative quantity, toxicity and area affected by
                          the Regulated Substances for which the respective
                          parties are responsible;

                   (iii)  The degree to which the Regulated Substance for which
                          a party is responsible affects the selection of the
                          remedy, the cost of the remedy, and the period of
                          time over which the remedy must be implemented;

                   (iv)   Other relevant considerations.

<PAGE>   178
         (f)     ACCESS.  Buyer acknowledges that investigation and remediation
of Environmental Conditions at the Distribution Facilities may include testing,
monitoring and other activities at the Distribution Facilities related to the
Environmental Conditions.  Buyer shall provide Seller and Seller's consultants,
contractors and agents with access to, and reasonable accommodation at, the
Distribution Facilities for such purposes under the same arrangements as
provided under Sections 8.5(j)(i) through 8.5(j)(vii).

         8.7.    ENVIRONMENTAL INDEMNIFICATION CAP.

         (a)     Seller's Indemnification Obligations (as defined in Section
8.7(b)) shall terminate, and Seller shall have no further obligations
thereunder, when the aggregate of the following payments and expenditures by
Seller exceeds $34 million, subject to adjustment as provided in Section 8.7(e)
(the "ENVIRONMENTAL CAP"):

                   (i)    Payments made to Buyer and its successors or
                          permitted assigns (each of which shall be deemed to
                          be included in the term "Buyer" as used in this
                          Section 8.7) or any other entity or person for
                          indemnification or defense of Claims arising from
                          Pre-Closing Environmental Conditions, Identified
                          Environmental Conditions, or Other Environmental
                          Conditions at the Properties ("INDEMNIFICATION

                          Aristech Environmental Conditions (such as cleanup of
                          post-Closing spills caused by Seller on the Retained
                          Premises) shall not be applied against the
                          Environmental Cap.

                   (ii)   Expenditures incurred by Seller in response to any
                          Environmental Condition at the Properties (including
                          Pre-Closing Environmental Conditions, Identified
                          Environmental Conditions, Other Environmental
                          Conditions and, to the extent, if any, Seller does
                          not receive indemnification therefor, those matters,
                          such as Buyer Environmental Conditions, as to which
                          Buyer has an indemnification obligation under this
                          Article VIII).

                   (iii)  Expenditures incurred by Seller in response to any
                          Pre-Closing Environmental Condition at the Retained
                          Premises to the extent that such Environmental
                          Condition is caused or exacerbated as a result of any
                          action by Buyer or any failure by Buyer to act where
                          Buyer has an obligation to act arising under law,
                          this Agreement, or any Ancillary Document ("BUYER
                          EXACERBATED CONDITIONS").  The aggregate amount of
                          expenditures under this clause (iii) that may be

                          applied against the Environmental Cap is $4 million
                          (subject to escalation as provided in Section 8.7(e)).


         (b)     "INDEMNIFICATION OBLIGATIONS" means all obligations of Seller
under this Article VIII to indemnify, defend, save and hold harmless Buyer
Indemnitees in respect of any of the matters described in Sections 8.7(a)(i)
and 8.7(a)(ii).  The term shall include any payments made directly by Seller to
third parties in respect of such indemnification obligations.

         (c)     Anything to the contrary herein notwithstanding, payments made
and expenditures incurred with respect to Sections 8.3(a) and 8.3(b) shall not
be applied against the Environmental Cap.

         (d)     Buyer (on behalf of itself and its successors and assigns)
hereby releases and forever discharges Seller, its successors and assigns, from
Seller's Indemnification Obligations and from any and all Claims of every kind,
name and nature, which Buyer had, has, or may in the future have against
Seller, with respect to (i) Environmental Conditions at the Properties and (ii)
Pre-Closing Environmental Conditions at the Retained Premises that are Buyer
Exacerbated Conditions, to the extent that such Indemnification Obligations and
Claims exceed the Environmental Cap.

         (e)     The Environmental Cap and the $4 million figure referred to in
Section 8.7(a)(iii) (the "RETAINED PREMISES CAP") shall be escalated on a
quarterly basis in accordance with the methodology described in Schedule
8.7(e).

         8.8.    TRANSFER OF BUYER'S ENVIRONMENTAL INDEMNIFICATION RIGHTS.
Buyer's rights under this Article VIII ("BUYER'S ENVIRONMENTAL INDEMNIFICATION
RIGHTS") shall not be transferable except as follows:

         (a)     Buyer may transfer Buyer's Environmental Indemnification
Rights to any of the following transferees:

                   (i)    the successor or surviving corporation in a corporate
                          merger or reorganization to which Buyer is a party;

                   (ii)   the company resulting from the incorporation by Buyer

         Ashland Chemical Company division of Buyer), or (Y) the sale of the
         Colton, California Business Site ("COLTON") without Seller's prior
         written consent, which consent shall not be unreasonably withheld.

                 (i)      (A)     Seller's failure to consent to any transfer
                                  referred to in clause (X) or (Y) of this
                                  Section 8.8(b) shall be deemed reasonable if

                                  historically had an adversarial relationship
                                  with Seller; (2) intends to use any of the
                                  facilities for any purpose other than the

                          (B)     In all other cases, Seller's failure to
                                  consent shall be presumed to be reasonable if
                                  any of the following criteria applies to the
                                  prospective transferee: (1) it has
                                  demonstrated (a) a lack of ability or
                                  intention to comply with Environmental Law,
                                  or (b) a recurring pattern or practice of
                                  violating Environmental Law; (2) it has
                                  engaged in unlawful activity under
                                  Environmental Law that is not being corrected
                                  to the satisfaction of the governmental
                                  agency or agencies with jurisdiction over the
                                  violation; or (3) it does not possess
                                  substantial experience in the production of
                                  chemical products.

             (ii)         Any assignment as to which Seller grants its consent
                          under this subparagraph (b) shall automatically, and
                          without any action on the part of Seller, Buyer or
                          Buyer's transferee, give rise to the caps described
                          in clauses (A) through (D) of this Section 8.8(b)(ii)
                          and the releases set forth in Section 8.8(b)(iii).

                          (A)     If Buyer sells all of the assets of Buyer's
                                  UPR business (including Colton), all of
                                  Buyer's Environmental Indemnification Rights

<PAGE>   184
                                  shall be subject to a cap equal to $15
                                  million, adjusted as set forth in Clauses (C)
                                  and (D) (the "UPR Cap").

                          (B)     (1)  If Buyer sells Colton prior to selling
                                  the remainder of the assets of Buyer's UPR
                                  business, Buyer shall have the option, upon
                                  prior written notice to Seller, of allocating
                                  up to $3 million out of the UPR Cap to
                                  Colton.  The amount so allocated to Colton
                                  shall become the "COLTON CAP", and the amount
                                  of the UPR Cap less the Colton Cap shall be
                                  the "REMAINING UPR CAP." (For example, if
                                  Buyer allocates $2 million of the UPR Cap to
                                  the Colton Cap, the Remaining UPR Cap shall
                                  be $13 million.)

                                  (2)  Upon the sale of Colton, all of Buyer's
                                  Environmental Indemnification Rights relating
                                  to Colton shall be subject to the Colton Cap;
                                  and the Environmental Cap provided in Section
                                  8.7 shall be reduced by the amount of the
                                  Colton Cap.  If no amount is allocated by
                                  Buyer to Colton, all of Buyer's Environmental
                                  Indemnification Rights with respect to Colton
                                  shall terminate upon the sale of Colton (that
                                  is, neither Buyer nor the purchaser of Colton
                                  from Buyer shall have any further rights

                                  Indemnification Rights with respect to matters
                                  relating to Colton).

                                  (3)  Upon the subsequent sale of the remainder
                                  of the assets of Buyer's UPR business, all of
                                  Buyer's Environmental Indemnification Rights
                                  with respect to such assets shall be subject
                                  to the Remaining UPR Cap, adjusted as set
                                  forth in Clauses (C) and (D).

                          (C)     The amount of the UPR Cap in effect
                                  immediately following a sale of Buyer's UPR
                                  business (including Colton) shall be $15
                                  million, less the aggregate Indemnification
                                  Payments and expenditures made by Seller in
                                  response to Environmental Conditions at the
                                  Properties during the period from Closing
                                  until the date of the sale.  If Colton is
                                  sold prior to a sale of the remainder of
                                  Buyer's UPR business: (1) the amount of the
                                  Colton Cap in effect immediately after the
                                  sale of Colton shall be an amount up to $3

                                  less all the Indemnification Payments and
                                  expenditures made by Seller in response to

                                  the Remaining UPR Cap that shall be in effect
                                  immediately after the subsequent sale of the
                                  UPR business shall be the UPR Cap minus the
                                  Colton Cap (determined as per clause (B)
                                  above), less (x) all Indemnification Payments
                                  and all expenditures made by Seller in
                                  response to Environmental Conditions at other
                                  Properties from the Closing until the date of
                                  sale of the UPR business, and (y) all
                                  expenditures made by Seller in response to
                                  Environmental Conditions at Colton from the
                                  Closing until the sale of Colton, to the
                                  extent not deducted under clause (1) of this
                                  Section 8.8(b)(ii)(C).

                          (D)     The amount of the UPR Cap and the Remaining
                                  UPR Cap shall be escalated on a quarterly

                                  forth in Schedule 8.7(e).  The Colton Cap

                                  effective upon the subsequent sale of the

                                  Seller, with respect to (i) Environmental
                                  Conditions at the Properties and (ii)
                                  Pre-Closing Environmental Conditions at the
                                  Retained Premises that are Buyer Exacerbated

         (c)     Except as provided in Section 8.8(a) or 8.8(b), Buyer may not
transfer any of Buyer's Environmental Indemnification Rights with respect to
any of the Properties, in part or as a whole, unless Seller, in its sole and
absolute discretion, approves the transfer in advance.  Seller may impose any
condition whatsoever on the grant of such approval, including the termination

         (d)     The assignee of, or successor to, Buyer's Environmental
Indemnification Rights in any transfer permitted under Sections 8.8(a) through
8.8(c) must assume or succeed to all of Buyer's obligations under this Article
VIII effective simultaneously with such transfer; provided, however, that no
such assumption shall relieve Buyer of its obligations under this Article VIII.

         (e)     In the event that the assignee of or successor to Buyer's
Environmental Indemnification Rights in any transfer permitted under Section
8.8(a) through 8.8(c) is not an entity that controls, is under common control
with or is controlled by Buyer, Buyer's Environmental Indemnification Rights
shall not be further assignable to any other person or entity by such assignee
or successor.  Buyer shall require as a condition precedent to any such
transfer that the transferee acknowledge to Seller in writing that it may not
assign Buyer's Environmental Indemnification Rights and that it is bound by the
release contained in Section 8.8(b)(iii).

         (f)     For purposes of this Section 8.8 the term "control" means
possession, directly or indirectly, of the power to direct or cause the

                                 MISCELLANEOUS
                                 -------------

         9.1.    ALTERNATIVE DISPUTE RESOLUTION PROCESS.  Except as provided in
Section 1.12, disputes regarding the application of any of the provisions of
this Agreement other than those contained Article VIII (which disputes are
governed exclusively by Section 8.3(k)) shall be subject to the following
alternative dispute resolution process:

         (a)     INVOCATION.  The resolution procedures shall be invoked when
either party sends a written notice to the other.  The notice shall describe
the nature of the dispute or conflict and the party's position with respect to
such dispute or conflict.  The parties shall expeditiously schedule
consultations or a meeting to discuss the dispute or conflict informally in
accordance with subparagraph (b) of this Section 9.1.

         (b)     DESIGNATION OF MANAGEMENT REPRESENTATIVES.  The following
Management Representatives have been designated for purposes of this Section
9.1:





                                    - 181 -
<PAGE>   191
                          For Buyer:       President, Ashland Chemical
                                           Company, or his or her designees.

                          For Seller:      President, Aristech Chemical
                                           Corporation, or his or her designees.

Any Management Representative designation may be changed by the appointing
organization, by written notice to the other party.

         (c)     INITIAL CONSULTATION.  Any conflicts or disputes shall, in the
first instance, be the subject of informal consultation and discussion between
an executive officer or management-level employee designated by Buyer's
Management Representative and an executive officer or management-level employee
designated by Seller's Management Representative.  The period of informal
consultations and discussions shall not extend beyond thirty (30) days from the
date of the first consultations or meetings between such designees, unless the
parties agree to extend this period.

         (d)     REFERENCE TO MANAGEMENT REPRESENTATIVES.  In the event that
the Management Representatives' designees are unable to reach agreement during
the informal consultation and discussion period under Section 9.1(c), the issue
shall be referred to the Management Representatives for informal negotiation.
The period of informal negotiations shall not extend beyond sixty (60) days
from the date of the first meeting between the Management





                                    - 182 -
<PAGE>   192
Representatives, unless the parties agree to extend this period.  The
Management Representatives may request the assistance of an independent
mediator if it is believed that the assistance of such a mediator would be of
assistance to the efficient resolution of the dispute.

         (e)     FORMAL RESOLUTION PROCEDURES.  In the event that the
Management Representatives are unable to resolve the matter within the period
provided in Section 9.1(d), the parties shall submit the dispute to binding
arbitration in Pittsburgh, Pennsylvania, or at such other location as the
parties may agree, in accordance with the terms of this subparagraph (e).

                 (i)      INITIATION OF ARBITRATION PROCESS.  Upon the
                          occurrence of a dispute, and failure of the parties
                          to resolve such dispute through the informal
                          processes described in Sections 9.1(c) and 9.1(d),
                          either party may initiate the arbitration process set
                          forth in this clause (i) by giving written notice to
                          the other party.

                 (ii)     SELECTION OF ARBITRATOR(S).  Within thirty (30) days
                          after the notice referred to in clause (i), the
                          parties shall either agree upon the appointment of a
                          single mutually-approved independent Commercial
                          Attorney to serve as arbitrator; or, if the parties
                          are unable to agree





                                    - 183 -
<PAGE>   193
                          upon a single arbitrator, each of the parties shall
                          appoint a Commercial Attorney to serve as arbitrator,
                          and the two individuals so named shall, within thirty
                          (30) additional days, agree upon a third independent
                          Commercial Attorney to serve as the third arbitrator.
                          The parties shall mutually cooperate to retain the
                          arbitrator(s) upon terms and conditions mutually
                          satisfactory to the parties as soon as practicable
                          after selection of the arbitrator(s).  For purposes of
                          this clause (ii) the term "Commercial Attorney" shall
                          mean an attorney having at least ten (10) years
                          experience in commercial transactions of the type
                          contemplated by this Agreement and in the preparation,
                          negotiation and interpretation of the documentation of
                          such transactions.

                 (iii)    FEES.  The fees of the arbitrator(s) shall be paid
                          one-half by Seller and one-half by Buyer.

                 (iv)     DISCOVERY.  For a period of sixty (60) days following
                          the appointment of the arbitrator(s) (or such longer
                          period as the parties may mutually agree or the
                          arbitrator(s) may direct), the parties shall have the
                          right to engage in such discovery relevant to the
                          matters in dispute as is





                                    - 184 -
<PAGE>   194
                          allowed pursuant to the discovery rules of the
                          Pennsylvania Rules of Civil Procedure.

                 (v)      RESOLUTION.  The arbitrator(s) shall decide such
                          disputes pursuant to the Commercial Arbitration Rules
                          of the American Arbitration Association in force at
                          the time of the arbitration.  The arbitrator(s) shall
                          be required to make a final determination, not
                          subject to appeal, within thirty (30) days from the
                          receipt of such dispute by the arbitrator(s), and the
                          parties shall be bound by the terms of such final
                          determination.  Where three arbitrators are
                          appointed, the decision may be rendered by a majority
                          of the arbitrators.  The determination by the
                          arbitrator(s) shall be made in writing and shall
                          contain written findings of fact, and may be
                          specifically enforced by a court of competent
                          jurisdiction.  The arbitrator(s) shall determine a
                          fair and equitable allocation of the reasonable
                          expenses of the parties incurred in connection with
                          the resolution of any dispute hereunder.  Each party
                          shall bear its own attorney's fees, unless the
                          arbitrator(s) shall determine that the nature of the
                          action or defense of the losing party was frivolous,
                          in which event the arbitrator shall determine a fair
                          and equitable attorney's





                                    - 185 -
<PAGE>   195
                          fee to be paid by the losing party to the prevailing
                          party.

                 (vi)     INDEPENDENCE OF ARBITRATOR.  The arbitrator(s) shall
                          retain independence of all parties to this Agreement,
                          and neither party shall engage or attempt to engage
                          the services of the arbitrator(s) for any other
                          purposes without prior written notice to the other
                          party.

         9.2.    EXCLUSIVE REMEDY.  Except as provided in Sections 4.1, 4.6 and
4.7, the remedies provided in Article VII and Article VIII shall be the sole
and exclusive remedy of Buyer and Seller (and of any other of Buyer's
Indemnitees or Seller's Indemnitees), under or in connection with this
Agreement, the Ancillary Documents, any certificate or agreement delivered in
connection herewith or therewith or the transactions contemplated hereby and
thereby.  Subject to Sections 4.1, 4.6 and 4.7, the only legal action that may
be asserted by any party or with respect to any matter under this Agreement or
the Ancillary Documents shall be a contract action to enforce, or to recover
damages for the breach of, this Article VII or Article VIII.  Without limiting
the generality of the preceding sentence, no legal action sounding in tort or
strict liability may be maintained by any party.  Notwithstanding the
foregoing, Buyer shall be entitled to exercise all of the remedies to which it
is otherwise entitled under the Deeds.

WITH RESPECT TO BUSINESS INTERRUPTION COSTS IN ARTICLE VIII, IN NO EVENT SHALL
SELLER BE LIABLE TO BUYER (OR ANY OTHER BUYER INDEMNITEE) FOR ANY
CONSEQUENTIAL, INDIRECT, INCIDENTAL OR OTHER SIMILAR DAMAGES, INCLUDING WITHOUT
LIMITATION LOST PROFITS FOR ANY BREACH OR DEFAULT UNDER, OR ANY ACT OR OMISSION
ARISING OUT OF OR IN ANY WAY RELATING TO, THIS AGREEMENT, THE ANCILLARY
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY CONCERNING OR
RELATING TO ANY OF THE FOREGOING, UNDER ANY FORM OR THEORY OF ACTION
WHATSOEVER, WHETHER IN CONTRACT OR OTHERWISE.

         9.4.    SURVIVAL OF INDEMNIFICATION PROVISIONS.  The provisions of
Section 1.12, Article VII and Article VIII shall survive the Closing.

the parties.  Any failure of any of the parties to comply with any obligation,
covenant, agreement or condition herein may be waived by the party entitled to
the benefit thereof only by a written instrument signed by the party granting

such obligation, representation, warranty, covenant, agreement or condition
shall not operate as a waiver of or estoppel with respect to, any subsequent or
other failure.  Whenever this Agreement requires or permits consent by or on
behalf of any party hereto, such consent shall be given in writing in a manner
consistent with the requirements for a waiver of compliance as set forth in

<PAGE>   201
materiality of such item for the purpose of this Agreement and the Ancillary
Documents.  The parties make no representations or warranties to each other,
except as contained in this Agreement and the Ancillary Documents, and any and
all prior representations and warranties made by any party or its
representatives, whether verbally or in writing, are deemed to have been merged

this Agreement and the Ancillary Documents.

    9.11.        NO ASSIGNMENT.  Except to the extent expressly provided in

    9.14.        NO THIRD PARTY BENEFICIARIES.  This Agreement is not intended

parties hereto (and, solely with respect to Article VII and Article VIII, the
Buyer Indemnitees and Seller Indemnitees) and their respective successors and
permitted assigns.

    9.15.        SEVERABILITY.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of
law, or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or
legal substance of the transaction contemplated hereby is not affected in any
manner adverse to any party.  Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable
manner to the end that the transaction contemplated hereby is fulfilled to the
extent possible.

    9.16.        COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original but all of which
together shall be deemed to be one and the same instrument.
