and subject to the conditions of this Agreement, HoldCo shall assume, effective
as of the Closing, and from and after the Closing, HoldCo shall pay, perform
and discharge when due, and indemnify Ashland and its affiliates and each of
their respective Representatives against, and defend and hold them harmless
from, all of the following liabilities, obligations and commitments of any
nature, whether known or unknown, express or implied, primary or secondary,
direct or indirect, liquidated, absolute, accrued, contingent or otherwise
and whether due or to become due, of Ashland (collectively, the "Assumed
Liabilities"), other than any Retained Liabilities:

       the Assigned Contracts to the extent such liabilities, obligations and
       commitments relate to the period from and after the Closing;

             (ii) all liabilities, obligations and commitments of Ashland under
       any maleic anhydride product exchange agreements that are reflected in
       the Statement (as

       defined in Section 1.05(a)) in accordance with Section 1.05;

             (iii) all liabilities, obligations and commitments of Ashland to
       the extent expressly assumed by HoldCo in accordance with Section 4.03;

             (iv) all Environmental Liabilities (as defined in Section 6.01(b))
       of Ashland to the extent they arise out of both (A) the operation of any
       of the Transferred Assets or the operation or conduct of the Maleic
       Business and (B) either (x) events occurring or circumstances or
       conditions arising from and after the Closing, or (y) events occurring
       or circumstances or conditions arising prior to the Closing, but only,
       in the case of this clause (B)(y), to the extent set forth in the table
       below (provided, however, that to the extent the same Environmental
       Liability is described in both clauses (x) and (y) of this Section
       1.03(a)(iv)(B), such Environmental Liability will be apportioned between
       HoldCo and Ashland in proportion to the extent to which the activities
       of each party contributed to the cause of the Environmental Liability,
       taking into account all pertinent factors, including the length of
       ownership by HoldCo and Ashland of the relevant property during the time
       of the event or occurrence, or the development of the circumstance or
       condition, giving rise to the Environmental Liability and the use made
       of such property by the parties hereto):

Environmental Liability is                      (B)(y) above that will be an

; and

             (v) all other liabilities, obligations and commitments of Ashland
       to the extent such liabilities, obligations and commitments relate to or
       arise out of the operation of any of the Transferred Assets or the
       operation or conduct of the Maleic Business, in each case from and after
       the Closing.

             (b)  Notwithstanding Section 1.03(a), or any other provision of
this Agreement, HoldCo shall not assume, and Ashland shall pay, perform and
discharge when due, and indemnify HoldCo and its affiliates and each of their
respective Representatives against, and defend and hold them harmless from, any
liability, obligation or commitment of Ashland or the Maleic Business of any
nature, whether known or unknown, express or implied, primary or secondary,
direct or indirect, liquidated, absolute, accrued, contingent or otherwise, and
whether due or to become due, except the Assumed Liabilities (collectively, the
"Retained Liabilities").  Without limiting the generality of the foregoing, the
Retained Liabilities include:

             (i) any liability, obligation or commitment of Ashland to the
       extent arising out of the operation or

<PAGE>

                                                                             9

       conduct by Ashland or any of its affiliates of any business other than
       the Maleic Business;

             (ii) all accounts payable of Ashland to the extent arising out of
       the operation or conduct of the Maleic Business prior to the Closing;

             (iii) any liability, obligation or commitment of Ashland (A) to
       the extent arising out of any actual or alleged breach by Ashland of, or
       nonperformance by Ashland under, any Contract (including any Assigned
       Contract) prior to the Closing or (B) under any Assigned Contract to the
       extent such liability, obligation or commitment relates to the period
       prior to the Closing;

             (iv) any liability, obligation or commitment of Ashland arising
       out of any warranty claim, suit, action, proceeding, investigation,
       governmental action or other cause of action or claim associated with or
       relating to the Maleic Business or the Transferred Assets (a "Claim") to
       the extent arising out of actions, omissions or conditions occurring or
       existing on or prior to the Closing Date;

             (v) any liability, obligation or commitment of Ashland to the
       extent such liability, obligation or commitment relates to, or arises
       out of, any Excluded Asset, or arises out of the ownership or operation
       by Ashland of any of the Excluded Assets;

             (vi) except as otherwise expressly provided in Section 4.03, any
       liability, obligation or commitment of Ashland arising under any Maleic
       Benefit Plan;

             (vii) any liability, obligation or commitment of Ashland to any of
       its divisions, subsidiaries or affiliates;

             (viii) any liability, obligation or commitment of Ashland or any
       of its affiliates under any of the Transaction Agreements or any of the
       Ancillary Agreements;

             (ix) the amount, if any, equal to the aggregate book value (as of
       the Closing Date) of all Receivables that are not collected after the
       Closing Date and remain outstanding for a period of more than 60 days

<PAGE>

                                                                            10

       after their respective due dates (as reflected in the books and records
       of the Maleic Business) notwithstanding that HoldCo has made reasonable
       efforts to collect such Receivables, which amount shall be promptly paid
       by Ashland to HoldCo and, until paid, shall be deemed for all purposes
       of this Agreement to be a Retained Liability; provided, however, in the
       event any one or more of the Receivables become Retained Liabilities
       under this clause (ix), promptly following Ashland's payment to HoldCo
       with respect to such Receivables under this clause (ix), HoldCo shall
       assign all of its rights, title and interests in, to and under such
       Receivables and, to the extent HoldCo thereafter receives any payments
       from the relevant customers on account of such Receivables, HoldCo shall
       promptly forward such payments to Ashland; and

             (x) any Environmental Liability arising out of events occurring or
       circumstances or conditions arising prior to the Closing except for
       Environmental Liabilities that are Assumed Liabilities pursuant to
       Section 1.03(a)(iv); provided, however, an Environmental Liability that
       otherwise would be considered a Retained Liability under this Section
       1.03(b)(x) shall be an Assumed Liability and shall not be a Retained
       Liability if the event, circumstance or condition that gave rise to such
       Environmental Liability (A) is the result of a change in use after the
       Closing Date of (x) any portion of the Premises consisting of the
       parcels of real property on which the maleic anhydride plant located in
       Neal, West Virginia (the "Plant") is located (which parcels are
       identified as such in Section 3.03 of the Maleic Business Disclosure
       Letter) to a use substantially unrelated to the use of such Premises as
       of the Closing Date or (y) any other portion of the Premises to a use
       other than an industrial use or (B) was discovered as a result of a
       Phase II or other intrusive sampling, testing or investigation conducted
       after the Closing Date (collectively, "Environmental Tests") except for
       Environmental Tests undertaken (x) to respond to, investigate, or
       otherwise remediate environmental conditions or contamination that are
       on the Closing Date in violation of the standards imposed by applicable
       Environmental Laws (as defined in Section 3.11(b)), (y) as required by
       Environmental Laws

<PAGE>

                                                                            11

       or in response to an inquiry, request, claim or demand by a
       Governmental Entity or as a reasonable response to any claim or demand
       by any other person that is not an affiliate of HoldCo or (z) in
       connection with a condition first discovered as a result of
       construction activities commencing after the Closing Date at, on or
       beneath the Premises, so long as such construction activities are
       undertaken in connection with (1) with respect to any portion of the
       Premises consisting of the parcels of real property on which the Plant
       is located, a use substantially related to the use of such Premises as
       of the Closing Date or (2) with respect to any other portion of the
       Premises, an industrial use of such Premises.

          (c) HoldCo shall acquire the Transferred Assets free and clear of
all liabilities, obligations and commitments of Ashland, other than the
Assumed Liabilities, and free and clear of all Liens, other than Permitted
Liens (as defined in Section 6.01(b)) and other than any Lien pursuant to the
HoldCo Borrowing arrangements or arising from actions or inactions of any of
the Marathon Parties or their affiliates (and not of any of the Ashland
Parties or their affiliates).

          SECTION 1.04. CONSENTS OF THIRD PARTIES. (a) Notwithstanding
anything to the contrary in this Agreement, this Agreement shall not
constitute an agreement to assign any asset or any claim or right or any
benefit arising under or resulting from such asset, or to assume any
liability, obligation or commitment, if an attempted assignment or assumption
thereof, without the Consent of a third party, would constitute a breach or
other contravention of the rights of such third party, would be ineffective
with respect to any party to an agreement concerning such asset, liability,
obligation or commitment, or would in any way adversely affect the rights of
Ashland or, upon transfer, HoldCo with respect to such asset, liability,
obligation or commitment. If any transfer or assignment by Ashland, or any
assumption by HoldCo, of any interest in, or liability, obligation or
commitment under, any asset requires the Consent of a third party, then such
transfer or assignment or assumption shall be made subject to such Consent
being obtained. Except as set forth in Section 1.04(b), Ashland shall not have
any liability or obligation under this Agreement arising out of or relating to
the failure to obtain any such Consent that may be

                                                                            12

required in connection with the Transactions contemplated by this Agreement or
because of any circumstances resulting therefrom, in each case so long as
Ashland shall have complied with its obligation under Section 9.11 of the
Master Agreement to use its reasonable best efforts to obtain such Consents.
Subject to Section 1.04(b), no representation, warranty or covenant of Ashland
herein shall be breached or deemed breached, and no condition shall be deemed
not satisfied, as a result of (i) the failure to obtain any such Consent, (ii)
any circumstances resulting therefrom or (iii) any Claim or investigation
commenced or threatened by or on behalf of any person arising out of or
relating to the failure to obtain any such Consent or any circumstances
resulting therefrom, in each case so long as Ashland shall have complied with
its obligation under Section 9.11 of the Master Agreement to use its
reasonable best efforts to obtain such Consents.

          (b) If any such Consent is not obtained prior to the Closing, the
Closing shall nonetheless take place on the terms set forth herein and,
thereafter, Ashland and HoldCo shall cooperate (at their own expense) in any
lawful and reasonable arrangement proposed by HoldCo under which HoldCo shall
obtain the economic claims, rights and benefits under the asset, claim or
right with respect to which the Consent has not been obtained in accordance
with this Agreement. Such reasonable arrangement may include (i) the
subcontracting, sublicensing or subleasing to HoldCo of any and all rights of
Ashland against the other party to such third-party agreement arising out of a
breach or cancellation thereof by the other party and (ii) the enforcement by
Ashland of such rights. With respect to the Assigned Contracts listed in
Section 1.04(b) of the Maleic Business Disclosure Letter, if the provision of
such economic claims, rights and benefits to HoldCo shall violate the rights
of such other party, Ashland shall otherwise compensate HoldCo for the
reasonable value, if any, of such economic claims, rights and benefits, so
long as HoldCo shall have complied with its obligations under the first
sentence of this Section 1.04(b).

          SECTION 1.05. CLOSING CURRENT ASSETS ADJUSTMENT. (a) Within 60 days
after the Closing Date, Ashland shall prepare and deliver to HoldCo a
statement (the "Statement"), setting forth Current Assets (as defined in
Section 1.05(d)) as of the close of business on the Closing Date ("Closing
Current Assets"). A physical inventory

<PAGE>

                                                                            13

shall be conducted jointly by Ashland and Marathon on or prior to the Closing
Date, in accordance with Section 1.05(a) of the Maleic Business Disclosure
Letter, for the purpose of preparing the Statement.

          (b) During the 30-day period following HoldCo's receipt of the
Statement, HoldCo and its Representatives shall be permitted to review the
working papers relating to the Statement. The Statement shall become final and
binding upon the parties on the 15th day following delivery thereof, unless
HoldCo gives written notice of its disagreement with the Statement (a "Notice
of Disagreement") to Ashland prior to such date. Any Notice of Disagreement
shall (i) specify in reasonable detail the nature of any disagreement so
asserted and (ii) only include disagreements based on mathematical errors or
based on Closing Current Assets not being calculated in accordance with this
Section 1.05. If a Notice of Disagreement is received by Ashland in a timely
manner, then the Statement (as revised in accordance with this sentence) shall
become final and binding upon Ashland and HoldCo on the earlier of (A) the
date Ashland and HoldCo resolve in writing any differences they have with
respect to the matters specified in the Notice of Disagreement or (B) the date
any disputed matters are finally resolved in writing by the Accounting Firm
(as defined below). During the 30-day period following the delivery of a
Notice of Disagreement, Ashland and HoldCo shall seek in good faith to resolve
in writing any differences that they may have with respect to the matters
specified in the Notice of Disagreement. At the end of such 30-day period,
Ashland and HoldCo shall submit to an independent accounting firm (the
"Accounting Firm") for arbitration any and all matters that remain in dispute
and were properly included in the Notice of Disagreement, in the form of a
written brief. The Accounting Firm shall be KPMG LLP or, if such firm is
unable or unwilling to act, such other nationally recognized independent
public accounting firm as shall be agreed upon by the parties hereto in
writing. Ashland and HoldCo shall instruct the Accounting Firm to render a
decision resolving the matters submitted to the Accounting Firm within 30 days
following submission. Judgment may be entered upon the determination of the
Accounting Firm in any court having jurisdiction over the party against which
such determination is to be enforced. The cost of any arbitration (including
the fees and expenses of the Accounting Firm and reasonable attorney fees and
expenses

<PAGE>

                                                                            14

of the parties) pursuant to this Section 1.05 shall be borne by HoldCo and
Ashland in inverse proportion as they may prevail on matters resolved by the
Accounting Firm, which proportionate allocations shall also be determined by
the Accounting Firm at the time the determination of the Accounting Firm is
rendered on the merits of the matters submitted. The fees and disbursements of
Ashland's Representatives incurred in connection with their preparation of the
Statement and their review of any Notice of Disagreement shall be borne by
Ashland, and the fees and disbursements of HoldCo's Representatives incurred
in connection with its review of the Statement shall be borne by HoldCo.

          (c) If Closing Current Assets is less than the line item comprising
Current Assets on the Balance Sheet (as defined in Section 3.01) ("Target
Current Assets"), Ashland shall, and if Closing Current Assets is more than
Target Current Assets, HoldCo shall, within 10 business days after the
Statement becomes final and binding on the parties, make payment by wire
transfer in immediately available funds of the amount of such difference,
together with interest thereon at a rate equal to the rate of interest from
time to time announced publicly by Citibank, N.A., as its prime rate,
calculated on the basis of the actual number of days elapsed divided by 365,
from the Closing Date to the date of payment.

          (d) The term "Current Assets" means the current assets of the Maleic
Business, calculated in the same way, using the same methods, as the line item
comprising current assets on the Balance Sheet, other than any current assets
relating to any Tax (as defined in the Tax Matters Agreement); provided,
however, that any liabilities, obligations or commitments of Ashland under any
maleic anhydride product exchange agreements in effect as of the Closing Date
shall be deducted, on a dollar for dollar basis, from current assets for
purposes of determining Closing Current Assets under this Section 1.05. The
foregoing principles are referred to in this Agreement as the "Balance Sheet
Principles". The parties acknowledge that the adjustment contemplated by this
Section 1.05 is intended solely to show the change in Current Assets from the
date of the Balance Sheet to the Closing Date, and that such change can only
be measured if the calculation is done in the same way, using the same
methods, for both dates. The scope of the disputes to be resolved by the
Accounting

                                                                            15

Firm shall be limited to whether Closing Current Assets was calculated in
accordance with the Balance Sheet Principles, and whether there were
mathematical errors in the Statement, and the Accounting Firm is not to make
any other determination, including any determination as to whether GAAP was
followed for the Balance Sheet or the Statement. Any items on or omissions
from the Balance Sheet that are based upon errors of fact or mathematical
errors or that are not in accordance with GAAP shall be retained for purposes
of calculating Closing Current Assets.

          (e) Following the Closing, HoldCo shall not modify the accounting
books and records of the Maleic Business on which the Statement is to be based
that would in any way affect the Balance Sheet or the Statement. Without
limiting the generality of the foregoing, no changes shall be made in any
reserve or other account existing as of the date of the Balance Sheet that
would in any way affect the Balance Sheet or the Statement except, in the case
of the Statement, as a result of events occurring after the date of the
Balance Sheet and, in such event, only in a manner consistent with past
practices of the Maleic Business. HoldCo shall cooperate in the preparation of
the Statement. HoldCo acknowledges that Ashland shall have the primary
responsibility and authority for preparing the Statement. During the period of
time from and after the Closing Date through the resolution of any adjustment
with respect to Closing Current Assets contemplated by this Section 1.05,
HoldCo shall afford to Ashland and its Representatives reasonable access
during normal business hours to all the properties, books, contracts,
personnel and records of the Maleic Business relevant to the preparation of
the Statement and the adjustment contemplated by this Section 1.05.

             SECTION 1.06. TAX MATTERS.  Notwithstanding anything to the
contrary in this Agreement, the rights, responsibilities and obligations of the
parties with respect to any Taxes or Tax Items (in each case as defined in the
Tax Matters Agreement) related to or arising from the ownership or operation of
the Maleic Business shall be determined pursuant to the Tax Matters Agreement.

             SECTION 1.07. NEVILLE ISLAND MALEIC ASSETS PROVISIONS.

             (a)  During the Option Period (as defined below), HoldCo shall be
entitled to elect to purchase from Ashland

<PAGE>

                                                                            16

all of Ashland's right, title and interest in, to and under the assets of the
maleic anhydride portion of the plant (the "Neville Island Maleic Facility")
located at Neville Island, Pennsylvania and the assets that are used, held for
use or intended to be used exclusively in the maintenance or operation of the
Neville Island Maleic Facility (collectively, the "Neville Island Maleic
Assets") by providing written notice to Ashland of such election (the "Option
Notice"). For the avoidance of doubt, the Neville Island Maleic Assets shall
not include any of the assets that are used, held for use or intended to be
used in the unsaturated polyester resin portion of the plant located at
Neville Island, Pennsylvania. If HoldCo exercises its right to purchase
hereunder, (i) the purchase price for the Neville Island Maleic Assets shall
be equal to the fair market value of the Neville Island Maleic Assets,
determined, as of the date on which HoldCo delivers the Option Notice to
Ashland, by Morgan Joseph & Co. Inc. (or such other independent investment
banking or appraisal firm as may be agreed upon by Ashland and HoldCo after
the Closing Date), using the same valuation methodology used by Morgan Joseph
& Co. Inc. for purposes of establishing the value of the Maleic Business in
connection with the Transactions being effected on the Closing Date under the
Master Agreement, (ii) Ashland and HoldCo shall use their reasonable best
efforts to cause the closing of the purchase and sale of the Neville Island
Maleic Assets to occur within 60 days of the date on which HoldCo delivers the
Option Notice to Ashland and (iii) the other terms of the purchase and sale
transaction shall be negotiated in good faith between Ashland and HoldCo,
provided that such terms and conditions shall be substantially consistent with
the terms and conditions applicable to the Transactions effected pursuant to
this Agreement. Ashland shall provide HoldCo at least two months' prior
written notice of the commencement of permanent demolition or disassembly of
the Neville Island Maleic Facility. "Option Period" means the period beginning
on the Closing Date and terminating and expiring upon the earliest to occur of
(i) 60 days after the date of a prior written notice to HoldCo by Ashland of
the commencement of permanent demolition or disassembly of the Neville Island
Maleic Facility (provided that commencement of such permanent demolition or
disassembly of the Neville Island Maleic Facility occurs promptly thereafter),
(ii) the sale of the Neville Island Maleic Assets to HoldCo or a third party
(provided that, in the case of a sale to a third party, Ashland shall have
complied with Section 1.07(b))or (iii) the fifth anniversary of the Closing
Date.

<PAGE>

                                                                            17

          (b) Ashland shall be free to negotiate with any third party to sell,
transfer or otherwise dispose of all or any portion of the Neville Island
Maleic Assets. Not fewer than 30 days nor more than 90 days prior to any
proposed sale, transfer or other disposition of all or substantially all of
the Neville Island Maleic Assets to a third party prior to the expiration of
the Option Period, Ashland shall provide HoldCo a written notice (the
"Proposed Sale Notice"), which shall (i) set forth the name of the proposed
purchaser and the principal terms and conditions of the proposed transaction,
including the consideration proposed to be received by Ashland in such
transaction and the proposed date for the closing of such transaction, and
(ii) offer to sell the Neville Island Maleic Assets to HoldCo on the same
terms and conditions described in the Proposed Sale Notice (provided, however,
that if any part of the consideration to be received by Ashland described in
the Proposed Sale Notice is in a form other than cash, HoldCo shall be
entitled to pay cash in an amount equal to the fair market value of such
consideration, as determined by an independent investment banking or appraisal
firm agreed upon by HoldCo and Ashland). If HoldCo desires to purchase the
Neville Island Maleic Assets on such terms and conditions, it shall provide
written notice of its election to do so (the "Exercise Notice") to Ashland on
or before the 30th day after the date HoldCo receives the Proposed Sale
Notice, and thereafter Ashland and HoldCo shall use their reasonable best
efforts to cause the closing of HoldCo's purchase on such terms and conditions
to occur on the proposed date for the closing of the transaction set forth in
the Proposed Sale Notice. In the event HoldCo does not give Ashland the
Exercise Notice or an Option Notice on or prior to the 30th day after the date
HoldCo receives the Proposed Sale Notice, then, during the immediately
following 60-day period, Ashland may sell all or substantially all of the
Neville Island Maleic Assets to the proposed purchaser named in the Proposed
Sale Notice on terms and conditions which are not materially less favorable,
taken as a whole, to such proposed purchaser than the terms and conditions set

not had and would not reasonably be expected to have a Maleic Business
Material Adverse Effect (as defined in Section 6.01(b)). During the past 12
months Ashland has not received any written communication alleging that

of the Transferred Assets or the Maleic Business after the Closing Date.

          (b) All Contracts listed in the Maleic Business Disclosure Letter

Assigned Contracts, and it is not in breach or default thereunder and, to the
knowledge of Ashland, no other party to any Assigned Contract is in breach or
default thereunder, in each case except for such noncompliance, breaches and

          SECTION 3.07. CONDITION OF TRANSFERRED ASSETS. The Transferred
Assets are in good operating condition and repair (ordinary wear and tear
excepted) and are suitable for their current uses, except where the failure of

Letter sets forth a list of each Claim pending or, to the knowledge of
Ashland, threatened against, or as to which a notice has been received as of

          SECTION 3.14. INVENTORY. Except as would not reasonably be expected
to have a Maleic Business Material Adverse Effect, the Inventory is generally
of a quality usable or salable in the ordinary course of the Maleic Business.

          SECTION 3.15. RECEIVABLES. Except as would not reasonably be
expected to have a Maleic Business Material Adverse Effect, the Receivables
have been collected, or are valid and enforceable claims arising in the
ordinary course of business and are, in the good faith belief of Ashland's
management, collectible, in the aggregate respective amounts so reflected on
the Balance Sheet, net of the applicable reserves (if any) reflected on the
Balance Sheet. Section 3.15 of the Maleic Business Disclosure Letter sets
forth, as of the date of this Agreement, all accounts receivable of Ashland
arising out of the operation or conduct of the Maleic Business which presently
remain unpaid and are owed by a debtor in any case under the Bankruptcy Code
or any other Law relating to bankruptcy or insolvency.

                                   Covenants
                                   ---------

          SECTION 4.01. COVENANTS OF ASHLAND RELATING TO CONDUCT OF MALEIC
BUSINESS. (a) Except for matters set forth in Section 4.01 of the Maleic
Business Disclosure Letter or otherwise contemplated by the Transaction
Agreements, from the date of this Agreement to the Closing, Ashland shall
conduct the Maleic Business in the usual, regular and ordinary course in
substantially the same manner as previously conducted, including completion of
the maintenance "turnaround" of the Plant currently scheduled for June 2004
and, to the extent not included in such turnaround, the item referred to in
Section 3.10 of the Maleic Business Disclosure Letter and items 1, 2, 3, 4
(except to the extent that work with respect to such item is projected to be
conducted during Ashland's 2005 fiscal year), 5, 6 and 7 in the capital
expenditure budget set forth in Section 4.01(a)(v) of the Maleic Business
Disclosure Letter. Without limiting the generality of the foregoing, Ashland
shall use its reasonable best efforts to (i) preserve the material business
relationships of the Maleic Business with customers, suppliers, distributors
and others with whom Ashland deals in connection with the conduct of the
Maleic Business in the ordinary course of business and retain its present
employees who are involved in the operation of the Maleic Business, (ii)
maintain the Transferred Assets, including those held under leases, in as good
operating condition and repair (ordinary wear and tear excepted) as at
present, and maintain all Permits set forth in Section 3.06 of the Maleic
Business Disclosure Letter, (iii) perform in all material respects its
obligations under Assigned Contracts and (iv) comply in all material respects
with all applicable Laws relating to the Maleic Business or any of the
Transferred Assets. In addition, except as set forth in Section 4.01 of the
Maleic Business Disclosure Letter or otherwise contemplated by the Transaction
Agreements, Ashland shall not do any of the following in connection with the
Maleic Business without the prior written consent of Marathon (which consent
shall not be unreasonably withheld or delayed):

             (i) adopt, establish or amend in any material respect any Maleic
       Benefit Plan (or any plan that would be a Maleic Benefit Plan if adopted
       or established) in a manner affecting any Maleic Business

<PAGE>

                                                                            31

       Employee, except as required by applicable Law or as would relate to
       a substantial number of other similarly situated employees of
       Ashland and its subsidiaries;

             (ii) grant to any Maleic Business Employee any increase in
       compensation or benefits, except in the ordinary course of business and
       consistent with past practice or as may be required under existing
       Contracts set forth in Section 3.05 of the Maleic Business Disclosure
       Letter and except for any increases for which Ashland shall be solely
       obligated and which will not result in any incremental compensation that
       will be payable by HoldCo after the Closing Date pursuant to
       Section 4.03(a);

             (iii) subject any Transferred Asset to any Lien of any nature
       whatsoever that would have been required to be set forth in
       Sections 3.02 or 3.03 of the Maleic Business Disclosure Letter if
       existing on the date of this Agreement;

             (iv) waive any claims or rights of substantial value to the extent
       relating to any Transferred Asset;

             (v) make or incur any capital expenditures (of a non-emergency
       nature) that relate to the Maleic Business and that are not reflected in
       the capital expenditure budget set forth in Section 4.01(a)(v) of the
       Maleic Business Disclosure Letter and that, individually, are in excess
       of $100,000 or that, in the aggregate, are in excess of $500,000, except
       for any such capital expenditures for which Ashland shall be solely
       obligated, provided, however, that if Ashland makes or incurs a capital
       expenditure that relates exclusively to the Maleic Business and is not
       reflected in the capital expenditure budget set forth in Section
       4.01(a)(v) of the Maleic Business Disclosure Letter, and if Marathon
       agrees in writing to cause HoldCo to reimburse Ashland for such capital
       expenditure, then HoldCo shall, promptly after the Closing, reimburse
       Ashland for such capital expenditure;

             (vi) sell, lease, license or otherwise dispose of any Transferred
       Assets, except (A) inventory, supplies and obsolete or excess equipment
       sold or disposed of in the ordinary course of business and (B) leases

<PAGE>

                                                                            32

       entered into in the ordinary course of business with aggregate annual
       lease payments not in excess of $50,000;

             (vii) enter into or amend any employee collective bargaining
       agreement or other Contract with any labor union;

             (viii) commit an intentional material breach of or waive any
       material rights under any material Assigned Contract or any material
       Permit, or amend or terminate any material Assigned Contract or any
       material Permit if the result of any such amendment or termination would
       be materially adverse to HoldCo; or

             (ix) authorize, or commit or agree to take, any of the foregoing
       actions.

          (b) ADVICE OF CHANGES. Ashland shall promptly advise Marathon in
writing of any change or event that has had or would reasonably be expected to
have a Maleic Business Material Adverse Effect.

          (c) INSURANCE. Ashland shall use its reasonable best efforts to
keep, or to cause to be kept, all insurance policies currently maintained with
respect to the Transferred Assets (the "Ashland Insurance Policies"), or
suitable replacements thereof, in full force and effect without interruption
through the close of business on the Closing Date; it being understood that
any and all Ashland Insurance Policies are owned and maintained by Ashland and
its affiliates (and do not exclusively relate to the Maleic Business). HoldCo
will not have any rights under the Ashland Insurance Policies from and after
the Closing Date.

          (d) SURVEY. During the 90-day period following the date of this
Agreement, Ashland shall afford to HoldCo, Marathon and their respective
Representatives reasonable access during normal business hours to the Premises
for the purpose of conducting an ALTA land title survey (at Marathon's
expense) of the Premises and all appurtenant easements. Following the
completion of that survey, a proper legal description of the Premises shall be
prepared and shall be attached to the deed referred to in Section 2.02(a).

          SECTION 4.02. REFUNDS AND REMITTANCES. After the Closing, if Ashland
or any of its affiliates receive any

<PAGE>

                                                                            33

refund or other amount which is a Transferred Asset or is otherwise properly
due and owing to HoldCo or any of its affiliates in accordance with the terms
of this Agreement, Ashland promptly shall remit, or shall cause to be
remitted, such amount to HoldCo. After the Closing, if HoldCo or any of its
affiliates receive any refund or other amount which is an Excluded Asset or is
otherwise properly due and owing to Ashland or any of its affiliates in
accordance with the terms of this Agreement, HoldCo promptly shall remit, or
shall cause to be remitted, such amount to Ashland. After the Closing, if
HoldCo or any of its affiliates receive any refund or other amount which is
related to claims (including workers' compensation), litigation, insurance or
other matters for which Ashland or any of its affiliates is responsible
hereunder, and which amount is not a Transferred Asset, or is otherwise
properly due and owing to Ashland or any of its affiliates in accordance with
the terms of this Agreement, HoldCo promptly shall remit, or cause to be
remitted, such amount to Ashland. After the Closing, if Ashland or any of its
affiliates receive any refund or other amount which is related to claims
(including workers' compensation), litigation, insurance or other matters for
which HoldCo or any of its affiliates is responsible hereunder, and which
amount is not an Excluded Asset, or is otherwise properly due and owing to
HoldCo or any of its affiliates in accordance with the terms of this
Agreement, Ashland promptly shall remit, or cause to be remitted, such amount
to HoldCo.

          SECTION 4.03. EMPLOYEE MATTERS.

          (a) CONTINUATION OF EMPLOYMENT. Effective as of the Closing, subject
to Section 4.03(d), HoldCo or one or more of its affiliates shall offer
employment (which shall include HoldCo's compliance with its covenants set
forth in this Section 4.03) to all Maleic Business Employees who on the
Closing Date are actively at work (each, an "Active Maleic Business
Employee"). For purposes of this Agreement, any Maleic Business Employee who
is not actively at work on the Closing Date due solely to a leave of absence
(including due to vacation, holiday, sick leave, maternity or paternity leave,
military leave, jury duty, bereavement leave, injury or short-term
disability), other than long-term disability, in compliance with applicable
policies of Ashland or its affiliates shall be deemed an Active Maleic
Business Employee. Each Maleic Business

                                                                            34

Employee who accepts such an offer of employment is referred to herein as a
"Transferred Maleic Business Employee". Immediately following the Closing,
HoldCo shall, or shall cause one or more of its affiliates to, provide each
Transferred Maleic Business Employee (i) with overall compensation that is at
least equivalent to such Transferred Maleic Business Employee's overall
compensation in effect immediately prior to the Closing and (ii) subject to
the provisions of this Section 4.03, with appropriate employee benefits as
determined by HoldCo or such affiliate.

          (b) CERTAIN WELFARE BENEFITS MATTERS. (i) Immediately following the
Closing, HoldCo or one or more of its affiliates shall allow Transferred
Maleic Business Employees to participate in benefit plans that provide for
group welfare benefits including, for the avoidance of doubt, vacation and
severance benefits (the "HoldCo Maleic Welfare Plans"). HoldCo shall grant to
the Transferred Maleic Business Employees credit for service prior to the
Closing with Ashland and its affiliates for all purposes under the HoldCo
Maleic Welfare Plans (other than the HoldCo Retiree Medical Plan (as defined
in Section 4.03(f))). HoldCo or its applicable affiliate shall (A) waive all
limitations as to preexisting conditions, exclusions and waiting periods and
actively-at-work requirements with respect to participation and coverage
requirements applicable to the Transferred Maleic Business Employees and their
dependents under the HoldCo Maleic Welfare Plans to the extent satisfied or
waived under the applicable corresponding Maleic Benefit Plan immediately
prior to the Closing and (B) provide each Transferred Maleic Business Employee
and his or her eligible dependents with either pro-rated deductibles and co-
payments for the balance of the year or credit for any co-payments and
deductibles paid prior to the Closing in the calendar year in which the
Closing Date occurs (or, if later, in the calendar year in which Transferred
Maleic Business Employees and their dependents commence participation in the
applicable HoldCo Maleic Welfare Plan) for purposes of satisfying any
applicable deductible or out-of-pocket requirements under any HoldCo Maleic
Welfare Plans in which the Transferred Maleic Business Employees participate.
If credit for deductibles and co-payments is provided, Ashland shall provide
or cause to be provided adequate data to implement that credit as HoldCo may
reasonably request.

                                                                            35

             (ii) Ashland shall be responsible in accordance with its applicable
       welfare plans (and the applicable welfare plans of its affiliates) in
       effect prior to the Closing for all reimbursement claims (such as
       medical and dental claims) for expenses incurred, and for all non-
       reimbursement claims (such as life insurance claims) incurred, under
       such plans prior to the Closing by Transferred Maleic Business Employees
       and their dependents, except that HoldCo shall be responsible for such
       claims to the extent such claims are reflected on the Statement or to
       the extent insured under an insurance policy of which HoldCo or its
       affiliates becomes the beneficiary and for which Ashland or its
       affiliates have paid the premium.  HoldCo shall be responsible in
       accordance with the applicable welfare plans of HoldCo and its
       affiliates for all reimbursement claims (such as medical and dental
       claims) for expenses incurred, and for all non-reimbursement claims
       (such as life insurance claims) incurred, from and after the Closing by
       Transferred Maleic Business Employees and their dependents.  For
       purposes of this Section 4.03(b)(ii), a claim shall be deemed to have
       been incurred on (A) the date of death or dismemberment in the case of
       claims under life insurance and accidental death and dismemberment
       policies or (B) the date on which the charge or expense giving rise to
       such claim is incurred (without regard to the date of inception of the
       related illness or injury or the date of submission of a claim related
       thereto) in the case of all other claims; provided, however, that in the
       event of a hospital stay that commences prior to the close of business
       on the Closing Date and ends after the close of business on the Closing
       Date, the cost thereof shall be apportioned between HoldCo and Ashland
       with Ashland responsible for that portion of the cost incurred prior to
       the close of business on the Closing Date and HoldCo responsible for the
       balance of such cost.  Effective as of the Closing, HoldCo shall assume
       all liabilities, obligations and commitments of Ashland and its
       affiliates to Transferred Maleic Business Employees and their eligible
       dependents in respect of health insurance under the Consolidated Omnibus
       Budget Reconciliation Act of 1985, as amended ("COBRA"), the Health
       Insurance Portability and Accountability Act of 1996 and applicable
       state Law; provided, however, that Ashland and its affiliates shall
       remain obligated to

<PAGE>

                                                                            36

       provide any applicable COBRA notices in respect of events occurring on
       or prior to the Closing Date.

          (c) ACCRUED VACATION. For purposes of determining the number of
vacation days to which each Transferred Maleic Business Employee shall be
entitled following the Closing, HoldCo shall assume and honor all vacation
days accrued or earned but not yet taken by such Transferred Maleic Business
Employee as of the Closing. To the extent that a Transferred Maleic Business
Employee is entitled under any applicable Law or any policy of Ashland or its
affiliates to be paid for any vacation days accrued or earned but not yet
taken by such Transferred Maleic Business Employee as of the Closing, HoldCo
shall discharge the liability for such vacation days.

          (d) COLLECTIVELY BARGAINED EMPLOYEES. HoldCo shall comply with all
applicable Laws relating to negotiations with unions in respect of the
Transactions contemplated by this Agreement and shall bear all expenses of any
compensation resulting from such negotiations. HoldCo shall indemnify Ashland
from, and hold it harmless against, any liability arising out of, attributable
to or resulting from HoldCo's nonassumption of any collective bargaining
agreement that covers one or more Transferred Maleic Business Employees;
provided, however, that such indemnification shall not include benefits and
obligations accrued and payable under Ashland's pension plans and employment
practices prior to the Closing.

          (e) PENSION BENEFIT. Immediately following the Closing, HoldCo or
one or more of its affiliates shall have in effect a retirement benefit plan
or plans (as applicable, the "HoldCo Retirement Plan") that shall provide
benefits to the Transferred Maleic Business Employees who immediately prior to
the Closing are salaried or non-union hourly employees. HoldCo shall grant
such Transferred Maleic Business Employees credit for service prior to the
Closing with Ashland and its affiliates for purposes of determining
eligibility to participate and vesting under the HoldCo Retirement Plan to the
same extent that such service is recognized for purposes of eligibility to
participate and vesting under the Ashland Inc. and Affiliates Pension Plan
(the "Ashland Pension Plan") as of the Closing Date.

          (f) RETIREE MEDICAL BENEFIT. Immediately following the Closing,
HoldCo or one or more of its

<PAGE>

                                                                            37

affiliates shall have in effect a retiree medical plan or plans (as
applicable, the "HoldCo Retiree Medical Plan") that shall provide benefits to
Transferred Maleic Business Employees who immediately prior to the Closing are
salaried or non-union hourly employees that are the same as those offered by
MAP to its employees, subject to MAP's right to amend or modify its retiree
medical plan in the ordinary course of business in accordance with the
reservation of rights provisions of such plan. HoldCo shall grant such
Transferred Maleic Business Employees credit for service prior to the Closing
with Ashland and its affiliates for purposes of determining eligibility to
receive retiree medical subsidies and for purposes of determining level of
benefits and benefit accruals under the HoldCo Retiree Medical Plan to the
same extent that such service is recognized for purposes of eligibility to
participate and vesting under the Ashland Pension Plan as of the Closing Date.

          (g) WARN ACT. HoldCo agrees to provide any required notice under the
Worker Adjustment and Retraining Notification Act, as amended (the "WARN
Act"), and any similar state Law that may be applicable to HoldCo, and to
otherwise comply with any such applicable Law with respect to any "plant
closing" or "mass layoff" (in each case as defined in the WARN Act) or group
termination or similar event affecting Maleic Business Employees (including as
a result of the consummation of the Transactions) and occurring on or after
the Closing Date. HoldCo shall notify Ashland after the Closing of any layoffs
of any Transferred Maleic Business Employees in the 90 day period after the
Closing.

          (h) ADMINISTRATION. Following the date of this Agreement, Ashland
and HoldCo shall reasonably cooperate in all matters reasonably necessary to
effect the transactions contemplated by this Section 4.03, including
exchanging information and data relating to workers' compensation, employee
benefits and employee benefit plan coverages (except to the extent prohibited
by applicable Law), and in obtaining any governmental approvals required
hereunder.

          (i) EMPLOYMENT TAX REPORTING RESPONSIBILITY. HoldCo and Ashland
hereby agree to follow the alternate procedure for employment tax withholding
as provided in Section 5 of Rev. Proc. 96-60, 1996-53 I.R.B. 24 ("Rev. Proc.
96-60"). Ashland shall provide HoldCo with all necessary and accurate payroll
records and such other

<PAGE>

                                                                            38

information relating to the Transferred Maleic Business Employees as HoldCo
may reasonably request with respect to Transferred Maleic Business Employees
in order to comply with the provisions of Rev. Proc. 96-60 with respect to the
calendar year that includes the Closing Date. HoldCo shall perform all
employment tax reporting responsibilities for such employees from the Closing
Date forward and shall furnish a Form W-2 for such calendar year to each
Transferred Maleic Business Employee that will include all remuneration earned
by such Transferred Maleic Business Employee from Ashland or HoldCo during
such calendar year.

          (j) INTENT. It is HoldCo's intent that overall compensation and
benefits provided by HoldCo to the Transferred Maleic Business Employees will
have comparable value to those provided to them by Ashland immediately prior
to the Closing. It is HoldCo's intent to provide competitive compensation and
benefits to all employees (including collectively bargained employees) at the
Plant.

          SECTION 4.04. POST-CLOSING INFORMATION. After the Closing, upon
reasonable written notice, Ashland and HoldCo shall furnish or cause to be
furnished to each other and their employees and Representatives, during normal
business hours, reasonable access to the personnel, properties, books,
Contracts, commitments, records and other information relating to the Maleic
Business (and, to the extent reasonably requested, copies of the portions
relating to the Maleic Business of any such books, Contracts, commitments,
records and other information, in each case to the extent they are available
in written form and they relate to the period prior to the Closing Date) and
assistance relating to the Maleic Business (to the extent within the control
of such party), in each case for any reasonable business purpose, including in
respect of litigation, insurance matters, financial reporting and accounting
matters.

          SECTION 4.05. RECORDS. HoldCo recognizes that certain Records may
contain incidental information relating to subsidiaries, divisions or
businesses of Ashland other than the Maleic Business and that Ashland may
retain copies thereof. Ashland recognizes that certain documents and
information of a type similar to the Records may be used, held for use or
intended to be used primarily in, or arise primarily out of, the operation or
conduct of the Maleic Business, and shall provide copies of the relevant
portions thereof to HoldCo at the Closing.

                                                                            39

          SECTION 4.06. AGREEMENT NOT TO COMPETE. (a) For a period of five
years from the Closing Date, Ashland shall not, and shall cause each of its
subsidiaries (other than Ashland-Suedchemie Kernfest GmbH and Ashland Avebene
S.A., in each case for so long as neither Ashland nor any of its subsidiaries
own, directly or indirectly and individually or collectively, more than 50% of
the equity interests of such entities) not to, directly or indirectly: (i)
engage in the business of manufacturing or marketing maleic anhydride
("Competitive Activities") within North America; provided, however, that this
clause (i) shall not apply to the marketing of briquette maleic anhydride
acquired from Marathon or any of its subsidiaries; (ii) solicit or recruit any
Transferred Maleic Business Employee; provided, however, that this clause (ii)
shall not apply to (A) a general advertisement or solicitation program that is
not specifically targeted at such persons or (B) any employee whose employment
by HoldCo has been terminated prior to such solicitation or recruitment; or
(iii) solicit any customer of the Maleic Business within North America or any
person who, within one year prior to the time of such solicitation, was a
customer of the Maleic Business within North America, for the purpose of
marketing maleic anhydride in competition with the Maleic Business in North
America with the knowledge of such customer relationship; provided, however,
that this clause (iii) shall not apply to the marketing of briquette maleic
anhydride acquired from Marathon or any of its subsidiaries. Notwithstanding
the foregoing, this Section 4.06(a) shall be deemed not breached as a result
of: (i) the ownership by Ashland or any of its subsidiaries of (A) less than
an aggregate of 10% of any class of stock of a person engaged, directly or
indirectly, in Competitive Activities or (B) less than 10% in value of any
instrument of indebtedness of a person engaged, directly or indirectly, in
Competitive Activities; or (ii) the acquisition by Ashland or any of its
subsidiaries of any person that, prior to the acquisition thereof, is not an
affiliate of Ashland and that engages, directly or indirectly, in Competitive
Activities within North America (A) if such Competitive Activities within
North America account for less than 20% of such person's consolidated annual
revenues for its most recently completed fiscal year or (B) if Ashland
disposes of or agrees to dispose of or discontinues such person's business
engaged in Competitive Activities within North America within one year after
the closing of such acquisition.

          (b) Ashland hereby agrees that the geographic and business scope and
the duration of the covenants and restrictions in this Section 4.06 are fair
and reasonable. However, if any provision of this Agreement is held to be
invalid or unenforceable by reason of the geographic or business scope or
duration thereof, the court or other tribunal is hereby directed to construe
and enforce this Section 4.06 as if the geographic or business scope or the
duration of such provision has been more narrowly drawn as so not to be
invalid or unenforceable, and such invalidity or unenforceability shall not
affect or render invalid or unenforceable any other provision of this
Agreement.

          (c) Ashland acknowledges that HoldCo will have no adequate remedy at
law if Ashland violates or breaches any term of this Section 4.06. In such
event, HoldCo shall have the right (upon compliance with any necessary
prerequisites imposed by law upon the availability of such remedies), in
addition to any other rights or remedies that it may have to obtain, in any
court of competent jurisdiction, injunctive relief to restrain any breach or
threatened breach of, or otherwise to specifically enforce the terms of, this
Section 4.06, and to exercise such remedies cumulatively or in conjunction
with all other rights and remedies provided by contract (hereunder or
otherwise, including the right to indemnity under Article XIII of the Master
Agreement), at law or in equity.

          (d) All the covenants in this Section 4.06 are intended by each
party hereto to, and shall, be construed as an agreement independent of any
other provision in this Agreement, and the existence of any claim or cause of
action of Ashland against HoldCo, whether predicated on this Agreement or
otherwise (other than a claim or cause of action of Ashland against HoldCo for
a material breach of the Maleic Supply Agreement that is continuing after
written notice by Ashland thereof and the expiration of a reasonable cure
period in accordance with the terms of the Maleic Supply Agreement), shall not
constitute a defense to the enforcement by HoldCo of any covenant in this
Section 4.06.

          SECTION 4.07. BULK TRANSFER LAWS. HoldCo hereby waives compliance
by Ashland with the provisions of any so-called "bulk transfer law" of any
jurisdiction in connection with the Maleic Assignment and Assumption.

<PAGE>

                                                                            41

          SECTION 4.08. SUPPLIES. At any time after 20 days after the Closing
Date, HoldCo shall not use stationery, purchase order forms, labels, material
safety data sheets or other similar paper goods or supplies that state or
otherwise indicate thereon that the Maleic Business is a division or unit of
Ashland.

          SECTION 4.09. MAIL. From and after the Closing, Ashland and HoldCo
shall cooperate with each other, and shall cause their Representatives to
cooperate with each other, to ensure that (i) HoldCo receives copies of all
mail (including mail sent by private delivery and electronic mail

(which HoldCo is hereby authorized to receive and open) that contains

reporting, accounting or tax purposes) or to subsidiaries, divisions or
businesses of Ashland other than the Maleic Business.

          SECTION 4.10. FURTHER ASSURANCES. From time to time after the
Closing, as and when requested by any party hereto, each party shall execute
and deliver, or cause to be executed and delivered, all such documents and
instruments and shall take, or cause to be taken, all such further or other
actions, as such other party may reasonably deem necessary or desirable to

                                                                            42

should be terminated and replaced on or prior to the Closing Date by a
separate Contract relating to the Maleic Business on the one hand (any such
separate Contract being an Assigned Contract, so long as (i) entering into
such Contract would not otherwise be in violation of this Agreement and (ii)
such Contract does not contain terms that, in the aggregate, are materially
less advantageous to the Maleic Business than the terms under the Contract
being terminated and replaced), and a separate Contract relating to such other
business of Ashland or any of its subsidiaries on the other hand (any such
separate Contract not being an Assigned Contract). If requested by HoldCo or
Marathon within 90 days after Ashland notifies HoldCo and Marathon in writing
of the specific terms of the Ashland Joint Contracts, Ashland shall continue
in effect any Ashland Joint Contract not terminated and replaced in accordance
with the immediately preceding sentence, if not prohibited by the terms of
such Ashland Joint Contract, until the stated expiration thereof (without
regard to any available renewal options); provided, however, that Ashland
shall not be prohibited from terminating any such Ashland Joint Contract
(other than the Car Service Contract dated as of April 16, 1990, between
Ashland and General American Transportation Corporation, the Car Leasing
Agreement dated as of January 3, 1984, between Ashland and General Electric
Railcar Leasing Services Corporation, the Car Service Agreement dated as of
April 1, 1989, between Ashland and Union Tank Car Company and the Master
Supplier Agreement dated as of January 1, 1990, between Ashland and Union Tank
Car Company) that relates to a substantial portion of the business of Ashland
and its subsidiaries. Each of Ashland and HoldCo shall perform its respective
obligations under all such Ashland Joint Contracts so as not to create a
default thereunder, and Ashland shall provide HoldCo with rights thereunder
consistent with historical practice between the parties with respect thereto,
subject to obtaining any necessary Consents from third parties (which Ashland
and HoldCo mutually agree to use their reasonable best efforts to obtain) and
subject to HoldCo bearing the proportionate expense attributable to such
rights consistent with historical practice between the parties with respect
thereto; provided, however, that neither Ashland nor HoldCo shall be obligated
to extend credit to the other party.

LLC Agreement is amended and restated to be Section 3.01(a), and a new Section
3.01(b) is added immediately thereafter as follows:

Percentage Interests of Ashland and Marathon will be determined as follows:
Ashland's Percentage Interest will equal the quotient, expressed as a
percentage, of (x) $2.915 billion plus the MAP Adjustment Amount (as defined
in the Master Agreement) minus the MAP Partial Redemption Amount (as defined
in the Master Agreement) divided by (y) $7.671 billion plus 100% of the
Distributable Cash of the Company as of the Closing Date minus the MAP Partial
Redemption Amount. Marathon's Percentage Interest will equal 100% minus
Ashland's Percentage Interest. The Percentage Interests of the Members will be
appropriately adjusted if the MAP Partial Redemption Amount is increased in
accordance with Sections 1.01 or 1.06 of the Master Agreement.

          SECTION 4. DISTRIBUTIONS

          Effective as of the date of this Amendment, Section 5.01 of the MAP

          SECTION 5.01. Distributions. (a) No distribution with respect to a
Tax Distribution Amount shall be made under this Section 5.01 with respect to
a Distribution Period, and the Tax Distribution Amount with respect to such
Distribution Period shall be $0.00, unless the Board of Managers, pursuant to
a vote in accordance with Section 8.07(b), determines that there shall be such
a distribution. If the Board of Managers, pursuant to a vote

<PAGE>

                                                                             8

in accordance with Section 8.07(b), determines that there shall be a
distribution under this Section 5.01 with respect to any Distribution Period
during a Taxable Year, then, within 45 days after the end such Distribution
Period, the Company shall distribute to the Members (the date of such
distribution being a "Distribution Date") an amount in cash (the "Tax
Distribution Amount") determined as follows:

          (i) The maximum Tax Liability of each Member with respect to its
     allocable portion (as provided in Section 6.03) of the Company's
     estimated taxable income for such Distribution Period shall be
     determined, based upon the highest aggregate marginal statutory Federal,
     state and local income tax rate (determined taking into account the
     deductibility, to the extent allowed, of income-based taxes paid to
     governmental entities) to which any Member may be subject for the related
     Fiscal Year (and excluding any deferred taxes) (the "Aggregate Tax
     Rate").

          (ii) If the Tax Liability determined in clause (i) is positive with
     respect to either Member, there shall be a cash distribution to each of
     the Members, in accordance with their Percentage Interests, of an
     aggregate amount such that neither Member shall have received
     distributions under this clause and subsection (b) below for such portion
     of such Fiscal Year in an amount less than its Tax Liability for such
     portion of such Fiscal Year.

          (b) No distribution of Distributable Cash shall be made under this
Section 5.01(b) with respect to a Distribution Period unless the Board of
Managers, pursuant to a vote in accordance with Section 8.07(b), determines
that there shall be such a distribution. If the Board of Managers, pursuant to
a vote in accordance with Section 8.07(b), determines that there shall be a
distribution under this Section 5.01(b) with respect to any Distribution
Period, the Company shall distribute to the Members such amount of
Distributable Cash as is determined to be distributed by such vote of the
Board of Managers. Subject to Section 5.02(b), each such distribution shall be
allocated between the Members pro rata based upon their respective Percentage
Interests.

          (c) The Company shall prepare and distribute to each Member within
45 days after the end of each

<PAGE>

                                                                             9

Distribution Period a statement (a "Distributions Calculation Statement")
setting forth the calculations (in reasonable detail) of (i) the Tax
Distribution Amount for each Member with respect to such Distribution Period
(as if the Board of Managers had determined that there shall be a distribution
under Section 5.01(a) for such Distribution Period, regardless of whether such
a determination was actually made), (ii) the amount of Distributable Cash with
respect to such Distribution Period (as if the Board of Managers had
determined that there shall be a distribution under Section 5.01(b) for such
Distribution Period, regardless of whether such a distribution was actually
made) and (iii) the allocation between the members of distributions, if any,
under Sections 5.01(a) and (b) for such Distribution Period. Such
Distributions Calculations Statements shall be distributed to such Members
regardless of the amount, if any, that is actually distributed to such Members
during such Distribution Period.

          (d) Notwithstanding anything to the contrary in this Agreement, any
agreement reached between the Members to distribute any amount of cash
different from the amounts which would be calculated in accordance with the
methodology set forth in Section 5.01(a) and Section 5.01(b) above shall not
alter or waive in any manner the obligations of the Company to prepare and
deliver the Distributions Calculation Statement as set forth in Section
5.01(c) above, and after any such agreement has been reached the Company shall
continue to prepare and deliver such Distributions Calculation Statement with
respect to each Distribution Period as if no such agreement had been reached.

          SECTION 5. PARTIAL REDEMPTION OF ASHLAND MEMBERSHIP INTEREST

          Effective as of the date of this Amendment, Article V of the MAP LLC
Agreement is amended by adding the following new Section 5.05:

          SECTION 5.05. MAP Partial Redemption. (a) On the MAP Partial

described in Section 1.01 of the Master Agreement by distributing to Ashland
the MAP Partial Redemption Amount in redemption of a portion of its Membership
Interest in the Company and by adjusting the Percentage Interests of the

no Tax

                                                                            10

Distribution shall be made with respect to the MAP Partial Redemption. The MAP
Partial Redemption Amount shall be distributed in cash and by the distribution
by the Company of the Distributed Receivables, each in the amount determined
in accordance with Section 1.01 of the Master Agreement. In connection with
the MAP Partial Redemption, on the Closing Date the Company shall, in
accordance with the Form of Receivables Assignment attached as Attachment A
hereto, (i) assign, transfer, or otherwise convey to Ashland, and Ashland
shall accept from the Company, the Distributed Receivables, together with all
Related Security and all Collections thereof (as such terms are defined in
Schedule 5.05 attached hereto) and (ii) shall distribute to Ashland cash (by
wire transfer of immediately available funds to a bank account, which will be
designated by Ashland at least two Business Days before the Closing Date). The
Company shall act as collection agent with respect to the Distributed
Receivables on behalf of New Ashland Inc. and pay the full amount of all
Collections thereof to New Ashland Inc. in accordance with the Collection
Policies and Procedures set forth in Schedule 5.05. A subsequent distribution
may be made with respect to any adjustments pursuant to Sections 1.06 or 9.13
of the Master Agreement.

          (b) If, in accordance with the pre-filing agreement (as referenced
in Section 7.06 of the Tax Matters Agreement) or as a result of any other
Final Determination with respect to the MAP Partial Redemption, Ashland is
determined to have received Section 751 Property in excess of the amount of
Section 751 Property which, had Ashland actually received such amount, would
have resulted in no gain recognition to Ashland under Section 751(b) of the
Code (such excess amount of Section 751 Property, the "Excess Section 751
Property"), the Members agree that Ashland shall be deemed to have exchanged
its share of Undistributed Cash for such Excess Section 751 Property for the
purpose of determining the amount of gain, if any, recognized by Ashland under
Section 751(b) of the Code; provided, however, that

<PAGE>

                                                                            11

if the total amount of Undistributed Cash is less than the fair market value
of the Excess Section 751 Property, then Ashland shall be deemed to have
exchanged, for an amount of Section 751 Property, its share of property other
than Section 751 Property, as designated by Ashland and Marathon prior to the
Closing Date, with a fair market value equal to its tax basis (the "Cold
Assets"); provided further, however, that the fair market value of such Cold
Assets shall equal the difference between the fair market value of the Excess
Section 751 Property and the total amount of Undistributed Cash. The Members
agree that any deemed exchange by Ashland of Undistributed Cash and/or Cold
Assets for Excess Section 751 Property pursuant to this Section 5.05(b) is
intended to be consistent with the principles of U.S. Treasury Regulation ss.
1.751-1(g), Example 3(c) and Example 5(d)(1).

          SECTION 6. MEMBER LOANS

          Effective as of the date of this Amendment, Article V of the MAP LLC

beginning on January 1, 2005 and ending on the date 45 days prior to the
Closing Date, Member Loans to Ashland shall be permitted on terms and
conditions consistent with the Company's historical practice with respect to
Member Loans, and Member Loans to Marathon shall be permitted pursuant to a
vote in accordance with Section 8.07(b). All Member Loans shall be repaid to
the Company by Ashland or Marathon, as applicable, no later than 30 days prior
to the Closing Date.

          SECTION 7. TAX ALLOCATIONS

          (a) Effective as of the date of this Amendment, Section 6.02(a) of

<PAGE>

                                                                            12

Marathon shall be allocated any Profit and Loss associated with Pass-Through
Items that would be allocable to Ashland in the absence of this Section 6.17
and that are attributable to a payment that is (1) described in Section
12.01(d)(vii) of the Master Agreement, which results in a special non-pro rata
distribution to Ashland, or (2) made with respect to the St. Paul Park QQQ
Project or the Plains Settlement (as both are described in Section 9.09 of the
Master Agreement).

          SECTION 6.18. Pre-Closing Allocation of Company Debt. Prior to the
Closing Date, the Company and the Members will take all steps necessary to
ensure that nonrecourse debt (within the meaning of U.S. Treasury Regulation
ss. 1.752-1(a)) is allocated to the Members for purposes of Section 752 of the
Code in a manner that results in each Member's share of aggregate Company debt
after the MAP Partial Redemption being equal to such Member's share of
aggregate Company debt immediately prior to such Redemption. For these
purposes, with respect to nonrecourse debt (within the meaning of U.S.
Treasury Regulation ss. 1.752-1(a)) if any, the Members agree to utilize, if
necessary to satisfy the preceding sentence, U.S. Treasury Regulation ss.ss.
1.752-3(a)(3) and 1.752-3(b).

          SECTION 6.19 Section 704(b) Book-Up. The Company shall determine the
value of each item (or class of items, as appropriate) of its assets as of the
MAP Partial Redemption Date, based on the report prepared by Deloitte & Touche
LLP and delivered to Ashland and Marathon in accordance with the definition of
AR Fraction in Section 1.01 of the Master Agreement and shall, immediately
prior to the MAP Partial Redemption, adjust the Capital Accounts of the
Members under Treasury Regulation ss.1.704-1(b)(2)(iv)(f) and (g), based upon
the amount of Profit and Loss that would be allocated to each Member under
Section 6.02 of this Agreement with respect to each such item or class as if
the Company sold all of its assets for such values immediately before the MAP
Partial Redemption (the "Section 704(b) Book-Up"). Any resulting differences
between the book and tax basis of property resulting from such Section 704(b)
Book-Up shall be accounted for under Section 6.03 using a method selected by
the Members.
