ITEM 2.  ACQUISITION OF ASSETS

     On August 10, 1998, Clark Refining & Marketing, Inc. ("Clark"), a wholly-
owned subsidiary of Clark USA, Inc. ("Clark USA") completed the purchase from BP
Exploration & Oil Inc., The Standard Oil Company, BP Oil Pipeline Company and BP
Chemicals Inc. (collectively, "BP") of BP's Lima, Ohio refinery, its Buckeye
Road crude oil terminal and Vine Street products terminal (collectively, the
"Lima Refinery") for $175 million, plus approximately $40 million for the
hydrocarbon inventory at the Lima Refinery on August 10, 1998 (the "Lima
Acquisition"). In addition, an estimated $50 million will be paid for crude oil
in transit currently owned by BP, the payment for which will occur over the two
months following August 10, 1998 as the crude oil is delivered to the Lima
Refinery. Such $50 million will be substantially funded through proceeds from
the sale of finished products over the same period.

     The Lima Refinery is a single train, fully integrated coking refinery that
has a rated crude oil throughput capacity of approximately 170,000 barrels per
day ("bpd"), which is expected to increase Clark's crude oil throughput capacity
from its current 370,000 bpd to approximately 540,000 bpd. The Lima Refinery is
a highly automated, modern oil refinery with a Nelson complexity rating of 8.7
and an estimated replacement cost of $1.2 billion. The Midwest location of the
Lima Refinery has historically provided it with a transportation cost advantage
and less gross margin volatility than refineries in other regions since demand
for refined products has exceeded supply in the region. The Lima Refinery
complements Clark's existing assets in the region as it is located in existing
core retail and wholesale markets where Clark already has distribution
capability.

     The Lima Refinery, which is located on a 650 acre site, was designed to
process light sweet crude oil and has historically run a predominately domestic
sweet crude oil slate. In addition to over five million barrels of on-site
storage and a rail products loading and unloading system, the Lima Refinery also
has access to a system of crude oil and product pipelines and terminals. At
approximately 170,000 bpd, the Lima Refinery is large enough to realize
economies of scale and other efficiencies. According to a 1994 industry study,
the Lima Refinery ranked in the 2nd quartile in terms of fixed costs and in the
1st quartile in operational availability, turnaround index and maintenance
index.

     Crude oil for the Lima Refinery can be obtained from a variety of sources
and transported through several crude oil pipelines. The Lima Refinery receives
100% of its crude oil supply via pipeline. Delivery routes include the Mid-
Valley, Salem-Stoy-Lima (SSL) and the Marathon pipeline systems as the three
crude pipeline systems with final delivery capability to the refinery, with
connections to Capline, Mobil, Ozark, IPL and other pipeline systems.
Historically, the Lima Refinery has been supplied by domestic crude oil moving
via the Mesa and West Texas Gulf pipeline into the Mid-Valley pipeline system.
Gulf Coast sourced foreign crude oil can be supplied to the Lima Refinery via
the LOOP/LOCAP system into Capline and then into the Lima Refinery either
through the SSL or Marathon pipeline systems. Canadian crude oil can be supplied
to the refinery through the IPL system which connects to the Marathon pipeline
system.

     The Lima Refinery distributes products through several refined product
pipeline systems and by rail, truck or the adjacent Vine Street terminal. Most
refinery products are distributed by using the Buckeye or Inland Pipeline
Systems. The Buckeye Pipeline System is a publicly held, common carrier,
interstate pipeline system with connections throughout the Midwest. Through
Buckeye, the Lima Refinery has access to markets in Northern/Central Ohio,
Indiana, Michigan and Western Pennsylvania. The Inland Pipeline System is a
private intra-state system jointly owned by BP, Shell, Unocal and Sun and
available solely for their use.

     The Lima Refinery is located in the U.S. Midwest PADD II (Petroleum Area
for Defense District), where demand for light products (gasoline and
distillates) has historically exceeded the region's refining production by
approximately 800,000 bpd. This light products shortfall has historically been
even more acute in Ohio. Ohio refining capacity is approximately 500,000 bpd.
However, even with this refining capacity, there are movements of approximately
130,000 bpd of light products into the state. Some of this additional light
product supply comes from
<PAGE>
 
refineries in adjoining states, including Michigan and Kentucky. Historically
there has been strong enough demand in Ohio to justify the cost of importing
production from other markets. Transportation costs for refined products from
the Gulf Coast to the Ohio market have averaged approximately $1.10 per barrel.

THE PURCHASE AGREEMENT
 
     The following summary of the purchase agreement is qualified in its
entirety by reference to the applicable provisions of the Agreement for the
Purchase and Sale of Lima Oil Refinery, dated as of July 1, 1998, and the Letter
Amendment No. 1, dated August 10, 1998, to the Agreement for the Purchase and
Sale of Lima Oil Refinery, dated as of July 1, 1998, ("Purchase Agreement")
which are attached as exhibits hereto.

     The Purchase Agreement provided for the purchase by Clark of all the
following: (i) the Lima Refinery, including all machinery and equipment used in
the operation of the Lima Refinery; (ii) the real property on which the Lima
Refinery is located, and certain related leased property; (iii) four crude oil
storage and blending tanks and the real property on which they are situated;
(iv) all hydrocarbon and non-hydrocarbon inventories at the Lima Refinery; (v) a
paid-up, nonexclusive, royalty-free license to use certain technology and
intellectual property of BP and its affiliates in the operation of the Lima
Refinery; and (vi) certain other assets as described in the Purchase Agreement
(collectively, the "Purchased Assets"). The purchase price for the Purchased
Assets equaled $175 million plus the market value of the hydrocarbon inventory
at the Lima Refinery at August 10, 1998, which is currently estimated at
approximately $40 million. In addition, an estimated $50 million will be paid
for crude oil in transit currently owned by BP, the payment for which will occur
over the two months following the Lima Acquisition as the crude oil is delivered
to the Lima Refinery. Such $50 million will be substantially funded through
proceeds from the sale of finished products over the same period. Clark also
agreed to assume and indemnify BP for all liabilities arising from the ownership
and operation of the Lima Refinery on or after August 10, 1998.

     The Lima Refinery was purchased with limited representations, warranties
and closing conditions. Subject to certain terms and limitations set forth in
the Purchase Agreement, BP agreed to indemnify Clark for all environmental and
other liabilities and obligations arising from the ownership and operation of
the Lima Refinery prior to August 10, 1998 or from the breach by BP of any
representation, warranty or covenant contained in the Purchase Agreement.
Indemnity claims for breaches of representations and warranties (other than
environmental matters) and certain pre-acquisition covenants must be brought
within one year after the Closing. Certain environmental indemnity claims
(including for breaches of representations and warranties) must be brought
within 17 years after the Lima Acquisition. Except for environmental matters,
Clark will not have a claim against BP for breaches of representations and
warranties and certain pre-acquisition covenants until the aggregate of all
losses for such matters exceeds $3.5 million and BP's aggregate liability for
such losses will not exceed $25 million.

     Clark has offered employment to the employees of the Lima Refinery.
However, because BP had previously announced that the Lima Refinery was to be
closed, many of such employees have accepted offers of employment with other
operations of BP. While BP has agreed to assist Clark in its efforts to retain
the Lima Refinery's employees, Clark has the risks associated with attracting
and retaining an appropriate workforce.

     Clark agreed to convey to BP Chemicals Inc. ("BP Chemicals") 15 acres of
the Lima Refinery's property in order to permit BP Chemicals to proceed with the
previously announced construction of a 1:4 Butanediol Plant ("BDO Plant") at the
Lima Refinery site. The specific location of the BDO Plant will be mutually
agreed upon by Clark and BP Chemicals. In addition, Clark has assumed certain
agreements with BP Chemicals and BP Oil Pipeline Company providing for the
purchase and sale by the Lima Refinery of propylene and certain other chemicals.
Clark and the parties to such agreements agreed to negotiate in good faith to
seek to enter into new long-term agreements for the purchase and sale of
propylene and such other chemicals.

SUMMARY OF CLARK'S ESTIMATES REGARDING THE LIMA ACQUISITION

Introduction

     BP has historically operated the Lima Refinery as a component of its
integrated global system and especially its Midwest refining and marketing
system. As a result, Clark believes that decisions such as those relating to
crude slate, yield, total throughput and capital expenditures were likely made
to optimize the performance of BP's entire integrated system, as opposed to that
of the Lima Refinery specifically. Clark is not acquiring the Lima Refinery's
sources of crude oil and other feedstocks, sales force, customer base or trade
names. There are no historical financial statements covering the Lima Refinery
on a stand-alone basis. Further, Clark believes any such financial statements
would not be meaningful for the reasons set forth above.

Clark's Estimates

     Clark believes that the Lima Acquisition will provide an opportunity to
improve Clark's operating results and cash flow. Clark and an independent energy
consulting firm ("Independent Energy Consultant"), reviewed the historical and
proposed operation of the Lima Refinery. Clark's estimates represent the
operating results of the Lima Refinery as if Clark had acquired the assets on
January 1, 1997 and operated them during 1997 based on Clark's


                                       2
<PAGE>
 
proposed operation of the Lima Refinery. Clark believes 1997 market prices are
appropriate since it is the last full year for which market prices are
available.

     Clark's estimates, set forth below, were developed as follows: (i)
feedstocks and refined product yields were based on BP's linear program and
modified by Clark during due diligence based on the assets being acquired, and
results of the linear program were then compared to actual charges and yield
data (which resulted in higher crude oil throughput, but yields which were more
conservative than the actual yields generated by BP in 1997), (ii) gross margin
was calculated using the applicable 1997 market prices, (iii) operating expenses
were based on actual historical performance with adjustments for higher crude
oil throughput and Clark's expected mode of operation and (iv) general and
administrative costs were estimated for those services previously provided by
BP's corporate staff. As discussed above, because BP had previously announced
that the Lima Refinery was to be closed, many employees have accepted offers of
employment with other operations of BP. While BP has agreed to assist Clark in
its efforts to retain the Lima Refinery's employees, Clark assumed the risks
associated with attracting and retaining an appropriate workforce and may thus
incur higher employment-related costs initially.

     Clark's estimates for the Lima Refinery included herein were not prepared
with a view toward compliance with published guidelines of the American
Institute of Certified Public Accountants or generally accepted accounting
principles. Neither Clark's independent auditors, nor any other independent
accountants, have compiled, examined or performed any procedures with respect to
Clark's or the Independent Energy Consultant's estimates regarding the Lima
Acquisition, contained herein, nor have they expressed any other form of
assurance on such information or its achievability, and assume no responsibility
for, and disclaim any association with the aforementioned estimates. These
figures represent Clark's best estimates of the operating and financial results
of the Lima Refinery had Clark operated it and the related assets in 1997 and
assuming Clark had been successful in implementing its anticipated changes and
expected mode of operation.

     Clark's estimates and underlying assumptions were independently reviewed
and confirmed by the Independent Energy Consultant. The Independent Energy
Consultant was furnished with information concerning the Lima Refinery available
to Clark, conducted a site visit and discussed the operations of the Lima
Refinery with management of BP and of Clark. Clark did not place any limitations
upon the Independent Energy Consultant with respect to procedures followed or
factors considered by the Independent Energy Consultant in rendering its
opinion. In the Independent Energy Consultant's opinion, the assumptions
underlying Clark's estimates provide a reasonable basis for Clark's estimates,
and Clark's estimates are reasonable.

     The success of Clark's planned operation of the Lima Refinery is subject to
uncertainties and contingencies beyond Clark's control, including business,
economic, regulatory and competitive uncertainties and contingencies. No
assurance can be given that the planned operations and anticipated benefits
would have been realized had Clark actually operated the Lima Refinery in 1997.
The gross margin and operating expense estimates are based on various
assumptions. Some of these assumptions may not materialize. Other assumptions
may materialize but in a subsequent period. Unanticipated events may occur
subsequent to the date of this document. The actual results achieved by Clark at
the Lima Refinery will vary from those set forth below and the variations may be
material. Consequently, the inclusion of the estimates herein should not be
regarded as a representation by Clark, the Independent Energy Consultant or any
other person that the estimates would have been achieved in 1997 or will be
achieved in the future. Prospective investors are cautioned not to place undue
reliance on these estimates.

     Clark does not intend to update or otherwise revise the estimates to
reflect circumstances existing after the date hereof or to reflect the
occurrence of unanticipated events, even in the event that any or all of the
assumptions are shown to be in error. Furthermore, Clark does not intend to
update or revise the estimates to reflect changes in general economic or
industry conditions. Clark's regular quarterly and annual financial statements
will be included in Clark's Quarterly Reports on Form 10-Q and Annual Reports on
Form 10-K, which will be filed with the Securities and Exchange Commission.
Information contained in such financial statements will be deemed to supersede
the estimates.

Estimated 1997 Lima Refinery EBITDA

     Clark estimates that the Lima Refinery would have generated $64.6 million
of earnings before interest, taxes, depreciation and amortization ("EBITDA") in
1997 after giving effect to the estimated processing rates, yields and operating
expenses. This estimate was based on (i) 1997 spot market prices for crude oil
and refined products adjusted for transportation differentials, (ii) feedstocks
and refined product yields based on the modification of BP's linear programming
model (which resulted in higher crude oil throughput, but yields which were more
conservative than the actual yields generated by BP in 1997), (iii) actual
historical operating expenses adjusted for higher throughput and Clark's mode of
operation and (iv) general and administrative costs estimated for those services
previously provided by BP's corporate staff.

     Clark's estimates for the Lima Refinery based on 1997 market prices are as
follows:

Summary of Clark's Estimate Assumptions

     In connection with the execution of the Purchase Agreement, Clark performed
limited due diligence on the Lima Refinery, including the review of information
provided by BP, discussions with the Lima Refinery manager and a preliminary
visit to the Lima Refinery. The results of this limited due diligence, together
with the more extensive due diligence performed in 1996, are the basis for
Clark's assumptions. The assumptions underlying the anticipated changes in
processing rates, yields and operating expenses are described below. The
estimates assume that (i) the Lima Acquisition occurred at January 1, 1997; (ii)
Clark successfully implemented its planned changes in processing rates, yields
and operating expenses; and (iii) BP assumed responsibility for environmental
remediation. Pursuant to the terms of the Purchase Agreement, Clark conduct a
more extensive due diligence review, including visits to the Lima Refinery and
interviews with key Lima Refinery personnel, between July 6 and July 10, 1998.

Feedstocks

     Clark assumed that domestic and foreign crude oil would have been purchased
at market prices and transported via available pipeline routes at published
tariff rates for delivery to the Lima Refinery, which is consistent with
historical operation. The mix of foreign and domestic crude oil feedstocks was
consistent with


                                       4
<PAGE>
 
historical throughputs. From 1995 to 1997, the Lima Refinery averaged
approximately 152,000 bpd of crude oil throughput and approximately 159,000 bpd
of total feedstocks. However, Clark believes the processing rates were limited
during this period due to the Lima Refinery's pending sale and closure. The
crude unit has a design capacity of approximately 170,000 bpd and processed
174,000 bpd for one week in November 1995. Therefore, Clark believes it can
achieve crude oil throughput of 160,500 bpd and total production of 165,000 bpd.

     Clark believes there may be a further opportunity to optimize the crude oil
inputs into the Lima Refinery by selecting more optimal crude oil types, but
such opportunity was not included in Clark's estimates.

Yields

     The Lima Refinery has historically been optimized as part of an integrated
system with BP's nearby Toledo refinery, the adjacent BP chemical operation and
the BP light product marketing network. As a result, Clark believes there is an
opportunity to optimize the Lima Refinery as a stand-alone operation to take
full advantage of the Lima Refinery's asset capability. Clark assumed the
products generated according to the linear programming model were sold at spot
market prices. The estimated product yields are more conservative than the
actual yields generated by BP in 1997.

Operating and General and Administrative Expenses

     Clark adjusted historical operating expense levels of the Lima Refinery
principally for higher throughput levels and the replacement of self-insurance
with premium-based insurance. Incremental general and administrative costs were
added for functions previously provided by BP's corporate staff and not
allocated to the Lima Refinery.

Capital Investment

     From 1991-1997, BP invested an aggregate of approximately $212 million in
the Lima Refinery. Based on due diligence, Clark expects mandatory capital
expenditures to average approximately $20 million per year for the period from
1999 to 2002 and turnaround expenses to cost approximately $30 million once
every five years. The Lima Refinery is scheduled to have the first such major
maintenance turnaround in 1999. Clark expects cash flows from the Lima Refinery
to be adequate to cover incremental financing and mandatory capital and
turnaround costs.

PURCHASE FINANCING

     To fund the purchase of the Lima refinery and certain related assets, Clark
(i) issued $110 million of 8 5/8% Senior Notes Due 2008 (the "Notes") in a
private placement to "qualified institutional buyers" and to non "U.S. persons"
(as defined in Rule 144A and Regulation S, respectively, of the Securities Act),
(ii) borrowed $115 million under a term loan agreement, dated as of August 10,
1998, among Clark, certain lenders and Goldman Sachs Credit Partners L.P., as
agent and (iii) used $5 million of available cash.

     The Notes will mature on August 15, 2008, and will be redeemable at the
option of Clark, in whole or in part, at any time on and after August 15, 2003
at 104.312% of principal amount thereof, plus accrued interest, reducing to
102.156% of principal amount thereof, plus accrued interest on August 15, 2004,
and to 100% of the principal amount thereof, plus accrued interest on August 15,
2005. In addition, up to 35% of the aggregate principal amount of the Notes may
be repurchased at a redemption price of 108.625% of the principal amount with
the proceeds from certain equity offerings.

     Clark entered into the First Amended and Restated Credit Agreement dated as
of August 10, 1998 (the "Term Loan") with a group of lenders led by Goldman,
Sachs Credit Partners, L.P., as administrative agent. The Term Loan amends and
restates a credit agreement, dated as of November 21, 1997 and provides for an
unsecured term loan of $115 million. The proceeds of the loan were used to fund
a portion of the purchase price of the Lima Acquisition. Interest under the Term
Loan is a floating rate equal to the London Interbank Offered Rate plus 2.75%.
The loans are scheduled to be repaid by November 15, 2004.

     The Notes and Term Loan contain covenants and conditions which, among other
things, limit dividends, indebtedness, liens, investments, asset sales and
mergers.

     In order to support the increased crude oil requirements of the Lima
Refinery, Clark amended its revolving facility to increase its size from $400
million to the lesser of $700 million or the amount available under a borrowing
base, as defined, representing specified percentages of cash, investments,
accounts receivable, inventory and other working capital items. Clark also
increased the borrowing sublimit from $50 million to $150 million.

FORWARD-LOOKING STATEMENTS

     The statements in this Form 8-K that are not historical information are
forward-looking statements within


                                       5
<PAGE>
 
the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. Words such as "expects," "intends," "plans,"
"projects," "believes," "estimates" and similar expressions are used to identify
such forward-looking statements. Any forward-looking statements are not
guarantees of future performance, involve significant risks and uncertainties
and actual results may vary materially from those in the forward-looking
statements as a result of various factors.

     Among the factors that could cause actual results to differ materially are
changes in industry-wide refining margins, changes in crude oil and other raw
material costs, and world and regional events that could significantly increase
volatility in the marketplace. Clark's crude oil supply could be affected by
factors beyond its control, such as embargoes, the continued discovery and
production of light sweet crude oil, or military conflicts between (or internal
instability in) one or more oil-producing countries. Clark's business is also
affected by the continued availability of debt and equity financing, changes in
labor relations, general economic conditions (including recessionary trends,
inflation and interest rates), market supply and demand for Clark's products,
the reliability and efficiency of Clark's operating facilities, the level of
operating expenses and hazards common to operating facilities (including
equipment malfunctions, plant construction/repair delays, explosions, fires, oil
spills and severe weather effects), actions taken by competitors (including both
pricing and expansion and retirement of refinery capacity in response to market
conditions), and civil, criminal, regulatory or administrative actions, claims
or proceedings (including domestic and international political, legislative,
regulatory and legal actions and regulations dealing with protection of the
environment, including gasoline composition and characteristics). Unpredictable
or unknown factors not discussed herein could also have material adverse effects
on forward-looking statements.

     Although Clark believes that its expectations regarding future events are
based on reasonable assumptions, it can give no assurance that these are all the
factors that could cause actual results to vary materially from the forward-
looking statements or that its expectations regarding future developments will
prove to be correct.

                    and licenses described in the Assignments of Leases/Licenses

                    material adverse effect on the present use or occupancy of
                    such real property. Except for the partial tax lots
                    described in Exhibit B of the deeds for the same, the

                    estate formerly known as the Wagner Farm shall be subject to
                    an Agreement for Right of First Refusal to Purchase or Lease
                    in accordance with the form and substance attached as

                      ownership and operation of the Refinery, the Tanks, the
                      pipelines described in Section 1.C., and the Vine Street
                      Terminal, as currently conducted. Except for matters
                      which, individually or in the aggregate, would not have a
                      material adverse effect on the present ownership or
                      operation of the same, the Refinery, the Tanks, the
                      pipelines described in Section 1.C. and the Vine Street
                      Terminal are all located within the boundary lines of the
                      real property to be transferred to Buyer hereunder, and

                      the Buckeye Road Property of any improvements on any
                      adjoining property.

               (iii)  Exhibit 5 sets forth a complete list of all real property
                      which is leased or licensed by the Seller and used in

                      Refinery and describes each of the leases and licenses
                      (including any amendments thereto) pursuant to which
                      Seller leases or licenses such real property ("Real
                      Property Leases"). To the best knowledge of Seller, such
                      Real Property Leases are free of all liens, and such Real
                      Property Leases are in full force and effect and grant in
                      all respects the leasehold estates or rights of occupancy
                      or use they purport to grant.

               (iv)   To the best knowledge of Seller, all water, sewer, gas,
                      steam, electric, telephone, access and drainage facilities
                      and all other utilities required by law and by the normal
                      operation of the Refinery Property are installed to the
                      boundaries of the Refinery Property, are connected to the
                      Refinery Property where appropriate with valid permits,
                      and are adequate to service the Refinery Property for the
                      present operation of the Refinery and to permit full
                      compliance with all applicable law.

               (v)    To the best knowledge of Seller, Seller has legal and
                      practical access to the public roads, pipelines and
                      railroad tracks needed for the ownership and operation of
                      the Refinery as presently operated and Seller has not
                      received and to the best of Seller's knowledge there do
                      not exist any adverse claims to such access that would
                      have a material adverse effect on the present ownership
                      and operation of the Refinery.

          F.   Brokers. All negotiations relating to this Agreement, and the
               transactions contemplated hereby have been carried on without the
               intervention of any person acting on behalf of the BP Group in
               such manner as to give rise to any valid claim against Buyer for
               any broker's or finder's fee or similar compensation in
               connection with the transactions contemplated hereby.

               provisions of Section 11.F) Seller has, and as of the Closing

               and G, and all other Purchased Assets constituting personal
               property free and clear of all liens and encumbrances. The
               Purchased Assets constitute all of the assets and other rights of
               Seller and their affiliates used in or necessary for the
               operation of the Refinery as currently conducted other than the
               Excluded Assets.

          H.   Compliance With Laws. To the best of Seller's knowledge, except
               as provided in Schedule F and except with respect to
               Environmental Laws (which are dealt with in Section 8. and
               Schedule I), the Purchased Assets are in compliance with all
               material laws, governmental regulations, order and decrees.

          I.   Permits. The Seller possesses all permits, licenses and
               governmental approvals, including the Environmental Permits
               required by Seller in connection with the operation of the
               Purchased Assets except for such permits, licenses and other
               governmental approvals the failure to possess would not,
               individually or in the aggregate, have a material adverse effect
               on the present ownership, operation, use, or occupancy of the
               Purchased Assets or the Assumed Liabilities.

          J.   Agreements. Schedule B lists or refers to all of the material
               Contracts affecting the Purchased Assets. Schedule B includes,
               but is not limited to Contracts (i) calling for payment by or to
               Seller arising out of the Purchased Assets over $100,000, per
               annum (ii) providing continuing obligations from or to any member
               of BP Group (whether or not material), (iii) containing covenants
               limiting the freedom of the Seller to compete in any line of
               business or with any Person in any geographical area, (iv)
               calling for the proposed acquisition of any operating business,

               or other inventory purchase agreements that extend beyond the
               Closing Date (collectively "Major Contracts"). Neither the Seller
               nor, to the best of Seller's knowledge, any party thereto, is in
               default under, or in breach of any material term or provision of
               any of the Major Contracts except as noted on Schedule B. Not

          K.   Proprietary Rights, Other Intellectual Property.  Schedule C
               contains a list of all patents and pending applications therefor,
               technology licenses and other agreements setting forth the items
               owned by Seller and the items licensed from third parties.
               Seller has the valid right to use the patents, patent
               applications, copyrights, copyright registrations, applications
               for the registration of copyrights, technical information,
               industrial know-how, technology and trade secrets, in each case
               owned or licensed by Seller or its affiliates in connection with
               the ownership or operation of the Refinery and all licenses or
               other agreements relating thereto ("Proprietary Rights") to the
               extent necessary in the current operations of the Refinery or the
               other Purchased Assets.  To the best of Seller's knowledge, the
               current operations of the Refinery and the other Purchased Assets
               and the use of the Proprietary Rights do not infringe any valid
               issued patent, or other right of any third party.  No claim by
               any third party contesting the validity, enforceability, use or
               ownership of the Proprietary Rights is currently outstanding or,
               to the best of Seller's knowledge, is threatened.  Except as
               disclosed on such Schedule, any such Proprietary Rights may be
               assigned or sublicensed (with respect to those Proprietary Rights
               to be sublicensed to Buyer pursuant to the Technology Transfer
               and License Agreement) to Buyer without the consent of any third
               party.

                    affiliates, involving or affecting the Purchased Assets for
                    which Buyer will be responsible or which will adversely
                    affect the Buyer whether seeking relief or redress under
                    Environmental Laws or seeking any injunctive relief, except
                    for such injunctive relief that if granted would be
                    insignificant to any of the Purchased Assets, nor is there
                    any basis known to Seller for any such action, suit,
                    proceeding or claim; and, except as disclosed on Schedule H
                    or Schedule I there are no decrees, injunctions, liens,
                    orders or judgments of or with any court or governmental

                    is pending or threatened seeking to restrain or prohibit
                    this Agreement, or any agreement, instrument or transaction
                    contemplated hereby, or to obtain damages, a discovery order
                    or other relief in connection with this Agreement or the
                    transactions contemplated hereby.

               employees employed at the Refinery. Except as set forth on
               Schedule J, Seller has not agreed to renew, or by failure to give
               notice allowed to renew, any collective bargaining agreement
               which would otherwise expire.

          N.   Absence of Certain Changes.
               
               (i)  Except as set forth on Schedule K or as provided for or

                         operation of the Refinery or other Purchased Assets
                         prior to the Closing Date, except as and to the extent
                         that such presence of Hazardous Substances can be shown

                         other Purchased Assets after the Closing Date. Seller
                         shall make available existing data and information

                         Refinery, and that such conditions will exist for the
                         foreseeable future. Buyer hereby expressly releases the
                         BP Group, Seller and BPC, and their successors and

                    (d)  Seller's Obligations For Waste Units. To the extent
                         that Corrective Action for Hazardous Substances
                         attributable to Waste Units as of the Closing Date is

                         the time of said Corrective Action, Seller shall, as
                         provided herein, undertake at its expense and (unless
                         otherwise agreed between the parties) under its control

                         reimbursement funds. Any Corrective Action undertaken
                         by Seller may be pursuant to applicable provisions of
                         the Ohio Voluntary Action Program, ORC Sections

                         Substances in connection with Seller's conduct of

                         facility;

                    (e)  Buyer's Obligations. To the extent Buyer undertakes at
                         its expense (subject to any applicable Indemnity from
                         Seller, as provided below) and under its control to
                         conduct Corrective Action at the Refinery or other
                         Purchased Assets (including without limitation
                         Corrective Action with respect to Hazardous Substances
                         at or emanating from the Refinery or other Purchased
                         Assets not attributable to Waste Units as of the
                         Closing Date), Buyer shall be entitled to the benefit
                         of any applicable reimbursement funds. In the event of
                         releases of Hazardous Substances on or after the
                         Closing Date in locations or amounts not readily
                         distinguished from Hazardous Substances known or
                         presumed to be the result of operation of the Refinery
                         or other Purchased Assets prior to the Closing Date,
                         Buyer shall be responsible for the incremental costs of
                         Corrective Action attributable to such releases. Buyer
                         shall provide to Seller information about releases
                         subsequent to the Closing Date sufficient to estimate
                         the incremental costs due to such releases. Buyer and
                         Seller shall work together in good faith to estimate
                         such costs. In the event the parties are unable to
                         reach agreement, the matter may be referred for Dispute
                         Resolution pursuant to Section 16.D.(ii) hereof. Where
                         the projected incremental costs associated with the
                         subsequent release exceed the projected remaining costs
                         for Corrective Action for which Seller is responsible,
                         Buyer shall assume control of the Corrective Action,
                         and Seller shall be responsible only for the increment
                         of costs over the costs attributable to the subsequent
                         release. Seller may either reimburse Buyer for its
                         share of such costs, or may, if the parties so agree,
                         pay a lump sum equal to the present value of projected
                         costs sufficient to complete all corrective actions
                         attributable to Waste Unit conditions as of the Closing
                         Date, and have no further responsibility with respect
                         to such conditions. In the event Buyer assumes control
                         of a Corrective Action pursuation equipment owned by
                         Seller and both located and used at the site of the
                         contamination assumed by Buyer may, at Buyer's option,
                         be conveyed to Buyer in exchange for an agreed price;

                         Section 8. (other than costs to the extent attributable
                         to the Waste Units) shall be aggregated. Such costs
                         shall include any costs resulting from Seller's
                         Indemnification under Section 16.B., to the extent such
                         Indemnification is the result of Corrective Action
                         matters within the scope of Section 8. (other than
                         costs to the extent attributable to Waste Units).
                         Seller shall provide Buyer an annual statement showing
                         expenditures of such costs. Buyer shall have the right
                         to review such non-privileged documents as may be
                         necessary to audit such costs. As of the date twelve
                         years after the Closing Date, the aggregate amount of
                         such costs shall be subtracted from Twenty Million
                         Dollars ($20,000,000). Seller shall pay to Buyer within
                         45 days after the expiration of said twelve year period
                         and amount equal to one-half of the amount, if any, by
                         which Twenty Million Dollars ($20,000,000) exceeds the
                         aggregate of such costs. Nothing in this section
                         8.C.(iii.)(c.) shall be construed to limit Seller's
                         responsibility for Compliance Actions or Corrective
                         Actions under this Agreement.

          D.   Buyer's Notice of Intent. Buyer shall provide Seller with 90
               day's advance notice, of Buyer's intent, prior to January 1,
               2019, to sell the Refinery or to cease or substantially curtail
               operations at the Refinery, or on 30 days' notice to change the
               scope, method or nature of operations at the Refinery, including,
               without limitation, the construction of new or modified
               structures at the Refinery, or undertaking excavations or
               geological investigations in connection with such construction,
               where such would reasonably be expected to lead directly or
               indirectly, including the consequence of the exercise of
               governmental agency discretion, to a significant increase in the
               cost of Corrective Action for which Seller is responsible, or to
               an acceleration of the timing of Corrective Action, or both.
               Buyer agrees to impose a similar obligation on purchasers of the
               Refinery. The parties agree that they will negotiate in good
               faith during the advance notice period to attempt to find
               alternatives agreeable to both parties, including without
               limitation re-purchase or throughput arrangements, which may
               efficiently or cost-effectively postpone or avoid the incurrence
               of additional remediation costs to the extent practicable.
               Buyer's investigation of the Refinery intended to identify
               contamination by Hazardous substances shall be limited to that
               (i) required under Environmental Law or other applicable legal
               requirements, or (ii) which a reasonable experienced refinery
               operator would undertake considering the totality of the
               circumstance, but disregarding the existence of any
<PAGE>


                                                                              24


               indemnity. It is the intent of Buyer and Seller that consistent
               with Environmental Laws the costs of the Corrective Actions be
               avoided or minimized. Buyer shall provide reasonable assistance
               and cooperation to Seller in efforts to avoid or minimize such
               costs.;

          E.   Access.

               (i)  Buyer and, if applicable, its designated representative
                    (herein "Owner") will permit access to and entry upon the
                    Refinery and other Purchased Assets to Seller and Seller's
                    designated representatives (herein "Licensee") as necessary
                    to conduct and complete Corrective Actions required pursuant
                    to this Agreement. In the event of a subsequent sale, lease
                    or other transfer of the Refinery and other Purchased 
                    Assets, Buyer shall require that Buyer's transferee agree to
                    the access provisions of this Section 8. Such access shall,
                    where necessary, include access to utility connections,
                    easements for installation of treatment facilities and
                    associated pipelines and utilities and connections and use
                    of wastewater treatment facilities. Seller will pay Buyer a
                    reasonable fee pursuant to Utilities and Services Agreements
                    for such utility and treatment facility use and such access
                    will be done in a manner so as not to unreasonably interfere
                    with Buyer's business. Buyer will cooperate in good faith
                    with Seller to ensure adequate and cost effective
                    performance of Corrective Action, including, where
                    appropriate, reasonable institutional controls including
                    deed restrictions, in light of the property's use as an
                    industrial facility, and not unreasonably impairing its
                    value or use for those purposes. Buyer and Seller agree to
                    negotiate in good faith an appropriate Right of Entry
                    Agreement and Utilities and Services Agreement which would
                    provide for any necessary terms and conditions, beyond those
                    identified herein, under which such access and services will
                    be provided;

               (ii) Except in the event of an emergency, Licensee shall provide
                    Owner with at least five (5) business days notice prior to
                    beginning any drilling, construction, and equipment
                    installation, as well as other activity that may disrupt
                    normal business operations on the Refinery or other
                    Purchased Assets . Licensee's activities shall not cause
                    undue disruption to Owner's business activities;

              (iii) Owner shall use its reasonable efforts not to unreasonably
                    interfere with the Licensee while Licensee exercises its
                    rights of ingress and egress to perform the Corrective
                    Action. Licensee shall perform the Corrective Action in a
                    manner which
<PAGE>


                                                                              25


                    minimizes disruption to Owner's business activities and to
                    the Refinery;

               (iv) Promptly upon completion of a Corrective Action, and except
                    as the Corrective Action may require a change in the
                    appearance or condition of a portion of the Property,
                    Licensee shall restore the Refinery or other property to
                    substantially the condition which existed immediately prior
                    to the commencement of the Corrective Action;

               (v)  Seller shall provide to Owner copies of final reports,
                    drawings, maps, appropriate project, operating and
                    maintenance files, correspondence with any governmental
                    authority, and sampling data related to, or which result
                    from, any actions on the Refinery or other Purchased Assets.
                    Owner shall provide to Licensee copies of any correspondence
                    with or between Owner and any applicable governmental
                    authority which involves or relates to any matters described
                    in this Agreement or which could reasonably impact
                    Licensee's actions at the Refinery or other Purchased
                    Assets. Upon Licensee's reasonable request, Owner shall
                    provide Licensee with such non-privileged final reports,
                    drawings, maps and appropriate project, operating and
                    maintenance records as may be useful for Licensee to examine
                    to determine whether operation of the Refinery or other
                    Purchased Assets has changed after the Closing Date, and
                    whether contamination is or may be the result of operations
                    at the Refinery or other Purchased Assets on or after the
                    Closing Date. Owner shall permit Licensee to examine and
                    copy such financial records as may be useful in determining
                    the reasonableness of expenditures for which Indemnity or
                    reimbursement is claimed;

               (vi) Prior to and during a Corrective Action, Licensee shall take
                    all steps which are reasonably necessary to prevent injury
                    to persons or damage to property resulting from or in any
                    way connected with the Corrective Action;

              (vii) Seller shall Indemnify the Owner against any Losses incurred
                    by Owner, and any liens and encumbrances that may be filed
                    or attach against the Refinery or any other Purchased
                    Assets, in connection with actions that Licensee performs on
                    the Refinery or any other Purchased Assets. No contractor,
                    subcontractor, materialman, agent, officer, director or
                    employee of the Licensee shall have any right to a lien
                    against the Refinery or any other Purchased Assets or any
                    part thereof for any work, labor or materials furnished to
                    Licensee for the actions performed on the
<PAGE>


                                                                              26


                    Refinery or any other Purchased Assets, unless otherwise
                    mandated by applicable law;

             (viii) Buyer will pay any and all costs, claims, rents or charges
                    which Seller may incur if reasonable access to the Refinery
                    or any other Purchased Assets is not granted in accordance
                    with this Agreement;

               (ix) Owner agrees to be responsible and reimburse Licensee for
                    any damage or loss that Owner, its employees, agents,
                    lessees, occupants of the Refinery or any other Purchased
                    Assets, contractors, successors or assigns cause, whether
                    sole, joint or concurrent, to any test or monitoring well,
                    remediation equipment and/or associated piping, or any other
                    property or equipment installed or otherwise used by
                    Licensee; and

               (x)  All equipment installed or used in the course of Corrective
                    Action shall remain the property of Licensee, and may be
                    removed upon completion of the Corrective Action.

          F.   Specific Matters. For avoidance of doubt, responsibility for the
               following matters is allocated as described below:

               (i)  Groundwater Treatment - Except as otherwise agreed, Seller
                    shall continue to own, as necessary, and operate the
                    groundwater recovery and treatment facilities, listed on
                    Schedule L, at the Refinery. Buyer shall, at Seller's cost
                    and request, but subject to there being available capacity,
                    treat any recovered groundwater from Corrective Action
                    operations in the Refinery's wastewater treatment plant. The
                    cost charged by Buyer to Seller for such treatment will
                    equal Buyer's incremental cost of providing such treatment;

               (ii) Construction - Where Buyer's plans for construction activity
                    will or may cause disturbance of soil, the parties will
                    consult to find the lowest total incremental cost method or
                    location of construction.

          9. DISCLAIMER. Except as otherwise expressly set forth in this
Agreement and the instruments, documents and agreements referred to herein or
executed in connection with the transaction contemplated hereby:

               (i)  Seller makes no representations or warranties of any kind or
                    nature with respect to itself, the Refinery, any portion
                    thereof or ANY OTHER ASSET TRANSFERRED TO BUYER PURSUANT TO
                    THE TERMS OF THIS AGREEMENT and
<PAGE>


                                                                              27


                    Seller hereby disclaims any implied warranties including
                    without limitation any implied warranties of merchantability
                    or fitness for a particular purpose;

               (ii) the Refinery AND ANY OTHER ASSETS TRANSFERRED TO BUYER
                    PURSUANT TO THE TERMS OF THIS AGREEMENT, are being
                    transferred "AS IS" and "WITH ALL FAULTS;" and

              (iii) Seller makes no warranty with respect to the condition of
                    any of the Refinery, the merchantability of the Refinery or
                    the fitness of any assets for any purpose and hereby
                    disclaims any and all warranties and representations of any
                    kind or nature.

          10. BUYER'S REPRESENTATIONS AND WARRANTIES. Buyer hereby represents
and warrants to Seller as of the date hereof and, as of the Closing Date, as
follows:

          A.   Organization and Good Standing. Buyer is a corporation duly
               organized, validly existing and in good standing under the laws
               of the State of Delaware.

          B.   Authority of Buyer. Buyer has full corporate power to enter into
               this Agreement and the transactions contemplated hereby and to

               performance of this Agreement and the transactions contemplated
               hereby have been duly authorized and executed by Buyer and this
               Agreement constitute valid and binding agreements of Buyer
               enforceable against Buyer in accordance with their terms except
               as such enforceability is limited by general principles of equity
               and applicable provisions of bankruptcy law.

          C.   No Violations. Except as provided in Schedule W the execution and
               delivery of this Agreement and the consummation of the
               transactions provided for hereby and the compliance by Buyer with
               any of the provisions hereof does not and will not: (i) violate
               any of the provisions of the Certificate of Incorporation or By-
               Laws of Buyer; (ii) result in the breach of, or constitute a
               default under, any material agreement or other instrument to
               which Buyer is a party or by which Buyer or any of its properties
               is bound; (iii) violate any order, injunction, judgment, federal,
               state, local or foreign law, ordinance, statute, rule or
               regulation, decree or award; or (iv) constitute an event which,
               with notice, lapse of time or both would result in any such
               violation, breach or default.

          D.   Litigation. To Buyer's knowledge, except as set forth on Schedule
               H or Schedule I, no action, suit, arbitration, proceeding or
               claim is pending
<PAGE>


                                                                              28


               or threatened seeking to restrain or prohibit this Agreement, or
               any agreement, instrument or transaction contemplated hereby, or
               to obtain damages, a discovery order or other relief in
               connection with this Agreement or the transactions contemplated
               hereby.

          E.   Brokers. All negotiations relating to this Agreement, and the
               transactions contemplated hereby have been carried on without the
               intervention of any person acting on behalf of the Buyer in such
               manner as to give rise to any valid claim against Seller for any
               broker's or finder's fee or similar compensation in connection
               with the transactions contemplated hereby.

          11. PARTIES' OBLIGATIONS PENDING THE CLOSING DATE. The parties agree
that from the date of this Agreement until the Closing Date:

          A.   Access and Information. Subject to the provisions of the letter
               agreement with respect to confidentiality dated June 11, 1998 and
               the BUTANEDIOL Process Disclosure Agreement effective June 18,
               1998 between Buyer and Seller (collectively the "Confidentiality
               Agreement") Seller will grant Buyer and its financing sources and
               their respective counsel, advisors and other representatives
               reasonable access (considering the Buyer's need to perform
               adequate due diligence in connection with this Agreement, to
               obtain financing for such and to have an orderly transition of
               the operation at Closing without disruption to the operations
               consistent with the Seller's need to maintain control of its
               business and avoid disruptions to the operations and all subject
               to a to be agreed protocol) during normal business hours
               throughout the period prior to the Closing Date to the Refinery
               and all of the Purchased Assets, books and records and other
               information relating to the operations of the Refinery and the
               other Purchased Assets and shall cause to be furnished to Buyer
               and its representatives all data and information concerning the
               Refinery and the other Purchased Assets (the "Data") concerning
               operations of the Refinery and the other Purchased Assets which
               may reasonably be requested by Buyer and shall make available
               such personnel of the Seller as may reasonably be requested for
               the furnishing of such Data;

          B.   Conduct of Business. Except as provided on Schedule K, Seller
               will operate the Refinery in the ordinary course consistent with
               past practice and Schedule E including making supply decisions
               and sales decisions use reasonable efforts to preserve intact its
               business organization and to maintain satisfactory relationships
               with suppliers, distributors, customers and others having
               business relationships with it; use reasonable efforts to
               maintain the Purchased Assets in good operating condition, normal
               wear and tear expected (and recognizing that for the past two
               years Seller has been planning to cease operating the Refinery);
               maintain its

                                                                              29


               inventory of supplies, parts and other materials and inventories
               and keep its books of account, records and files, in each case in
               the ordinary course of business consistent with past practice;
               refrain without Buyer's consent which shall not be unreasonably
               withheld from (A) amending, modifying, waiving any rights under
               or terminating (or allowing to terminate) any of the Contracts
               except in the ordinary course of business, (B) entering into any
               Contract that would be required to be listed on Schedule B if
               entered into prior to the date of this Agreement, (C) disposing
               of, encumbering, selling or otherwise transferring any of the
               assets or other rights of the Refinery except sales of inventory
               in the ordinary course of business, (D) commencing any new
               capital projects or making any additional commitments for capital
               expenditures relating to the Refinery in excess of $100,000 in
               the aggregate, or (E) grant or agree to grant any wage or salary
               increases or any bonus or other similar compensation to any
               employees of the Refinery except for any approved prior to the
               date hereof, or enter into any contract of employment, collective
               bargaining agreement or other labor contract with respect to any
               such employees. Except for those Contracts disclosed on Schedule
               B as of the date hereof, at Buyer's option, at Closing, Seller
               wiy of its affiliates and the Refinery not listed on Schedule B;

          C.   Schedules. Seller will advise Buyer in writing of additions or
               changes to the schedules to this Agreement required to reflect
               events since the date of this Agreement or facts discovered by
               Seller after the date hereof, so as to cause the representations
               in Sections 7, 8.B. and 12.A. to be true and correct, as amended
               on the Closing Date, which written notice from Seller shall set
               forth in reasonable detail the relevant event and all relevant
               facts relating thereto to enable Buyer to evaluate the possible
               consequences thereof. If in the reasonable judgment of Buyer, the
               said additions or changes individually or in the aggregate could
               reasonably be expected to result in a material adverse change to
               the Purchased Assets, Assumed Liabilities or the financial
               prospects of the Refinery taken as a whole, the parties will
               negotiate in good faith to determine a reasonable adjustment to
               the Purchase Price to fully reflect the Losses of Buyer resulting
               from such matters. If the parties fail to agree on an adjustment,
               the Buyer may terminate this Agreement before Closing, and no
               party shall have any liability to the others for such termination
               except as provided in Section 3.A.;

          D.   Title Policies. Buyer may procure, and will pay the cost of the
               premium for commitments from title insurance companies to provide
               owner's title insurance policies of the portions of the Purchased
               Assets constituting realty, subject to exceptions for charges,
               assessments and taxes not yet due and payable, exceptions for
               items which would be revealed by a survey and other standard
               exceptions, and exceptions for
<PAGE>


                                                                              30


               items which would not significantly interfere with the existing
               operations of the Refinery and providing that Buyer's ability or
               inability to obtain title insurance on the Refinery for any
               reason shall not be a pre-condition of the Closing;

          E.   H-S-R. If legally required, the parties will take all reasonable
               and expeditious steps to file the application and ensure
               expiration of the waiting period under the H-S-R Act without
               challenge; and

          F.   Assignments. With respect to any Contract or Permit which is
               intended to be assigned to Buyer hereunder and which requires
               consent for the assignment thereof to Buyer, Seller shall take
               such actions as are necessary, and Buyer shall cooperate with
               Seller, to effect assignment thereof to Buyer at Closing at no
               additional cost to Buyer or Seller and without any amendment or
               modification thereof without the written consent of Buyer, which
               consent will not be unreasonably withheld or delayed. In the
               event that the Seller is unable to obtain the requisite approval
               for assignment of any such Contract or Permit, or in the event
               such Permit is required to be amended or supplemented and is not
               so amended or supplemented as of the Closing Date, to Buyer, at
               the request of Buyer, (except in the case of Permits where such
               action would be unlawful), Seller shall (i) retain any such
               Contract or Permit and shall enter into an arrangement with Buyer
               to provide Buyer with the benefits of such Contract or Permit,
               provided Buyer shall perform Seller's obligations thereunder
               arising after the Closing Date with respect to the matter in
               question until such Contract or Permit is assigned to Buyer or
               expires at the earliest opportunity in accordance with its terms,
               is properly amended or supplemented, and (ii) shall take all
               action required to assign to Buyer, amend or supplement any such
               Contract or Permit as soon as practicable after Closing.

          G.   Casualty Repair. Seller agrees that if any assets of the Refinery
               or other Purchased Assets are destroyed or damaged, in whole or
               in part, by fire or other casualty or are subject to a
               condemnation or eminent domain order or proceeding prior to or on
               the Closing Date, Seller shall repair or replace such assets with
               reasonable promptness prior to the Closing Date, or at Seller's
               option, Seller may assign to Buyer all proceeds of any insurance
               net of expenses covering such assets and shall thereafter be
               relieved of any obligation to repair or replace such assets. If
               the insurance proceeds net of expenses are not sufficient to
               repair the damaged assets, Seller will pay to Buyer an amount
               equal to the replacement value of such asset less the insurance
               proceeds transferred to Buyer. Notwithstanding anything to the
               contrary herein, Seller shall not be obligated to expend an
               amount in excess of Fifty Million Dollars ($50,000,000).

          H.   Other Actions. Buyer and Seller shall otherwise use their
               respective commercially reasonable efforts to cause the
               satisfaction of all conditions precedent in Sections 13 and 14
               and the Closing to occur as soon as reasonably practicable after
               the date hereof.

          12.  EMPLOYEES and BENEFITS.

          A.   Representations and Warranties as to Employee Benefit Plans.

               (i)    Schedule M attached hereto contains a list of all of the
                      following employee benefit plans covered by the Employee
                      Retirement Income Security Act of 1974, as amended
                      ("ERISA") as specified maintained or contributed to by the
                      Seller on behalf of employees of the Refinery including 2
                      hourly employees at Buckeye Road and 3 Vine Street
                      Terminal employees referred to in Section 2.M. (the
                      "Employees" pl. or "Employee"(s)) (collectively, the
                      "Benefit Plans") or on behalf of former United States
                      employees including retirees of the Refinery:

                      (a)  nonqualified deferred compensation or retirement
                           plans subject to the ERISA;

                      (b)  qualified defined contribution or defined benefit
                           plans which are employee pension benefit plans (as
                           defined in Section 3(2) of ERISA) (the "Pension
                           Plans"); and

                      (c)  employee welfare benefit plans (as defined in Section
                           3(1) of ERISA).

               (ii)   The Seller Group makes no contributions on behalf of any
                      Employee to any multiemployer plans (as defined in Section
                      4001(a)(3) of ERISA) or has any withdrawal liabilities
                      with respect to any such multiemployer plans;

               (iii)  Seller Group has or will have made all employer
                      contributions required and due to be paid as of the
                      Closing Date with respect to any Pension Plan. The Pension
                      Plans have been funded in compliance with the applicable
                      minimum funding standards of ERISA, and Seller Group has
                      not sought a waiver of the minimum funding standards under
                      Section 412 of the Code;

               (iv)   The Pension Plans and their related trusts have been
                      maintained in compliance with the Code and the regulations
                      thereunder. Each of the Pension Plans and their related
                      trusts has been the subject of a favorable determination
                      letter under Sections 401(a) and 501(a) of the Code and no
                      such determination letter has
<PAGE>

                                                                              32
 
                      been revoked, nor has revocation been threatened. Each
                      such Pension Plan has been administered and operated in
                      accordance with its terms and in such a manner as to
                      preserve its tax-qualified status. No such Pension Plan
                      had an "accumulated funding deficiency" within the meaning
                      of Section 412(a) of the Code as of the end of the most
                      recently completed plan year;

               (v)    All material reporting or disclosure requirements to
                      federal, state and local governments and governmental
                      agencies and to all Benefit Plan participants and
                      beneficiaries have been satisfied with respect to the
                      Benefit Plans, and the Benefit Plans and any related trust
                      have been maintained in substantial compliance with ERISA
                      and any other applicable laws and regulations;

               (vi)   Seller and certain members of the controlled group of
                      corporations (within the meaning of Section 414(b) and (c)
                      of the Code) of which Seller form a part, presently
                      maintain one or more qualified defined benefit pension
                      plans which are not multiemployer plans but which are
                      subject to the provisions of Title IV of ERISA. With
                      respect to each such plan:

                      (a)  No asset of the Seller's is subject to a lien by
                           reason of the provisions of Section 412(n) of the
                           Code;

                      (b)  To the best of Seller's knowledge, there exists no
                           ground upon which the Pension Benefit Guaranty
                           Corporation ("PBGC") would demand termination of such
                           plan or appointment of itself or its nominee as
                           trustee thereunder; and

                      (c)  As of the Closing Date, no liability to the PBGC has
                           been incurred with respect to those Pension Plans
                           which are defined benefit plans other than premiums
                           due and not yet payable.

               (vii)  Except as disclosed in Schedule M, there are no pending
                      or, to the Seller's knowledge, threatened claims by or on
                      behalf of any of the Benefit Plans (as defined in Section
                      12.A.(i) above), by any employee or beneficiary covered
                      under such Benefit Plans (other than routine claims,
                      including appeals, for benefits) which could result in
                      liability against the Refinery.

          B.   Employee and Benefit Matters.

               (i)    On or prior to the Closing Date, Buyer shall offer
                      employment to all active Employees (including any employee
                      on leave under
<PAGE>

                                                                              33

                      the Family Medical Leave Act or similar legislation
                      ("FMLA"), after the Closing Date, if such former employee
                      is ordered reinstated pursuant to an award, or order of,
                      an arbitrator (but, at Seller's option, excluding up to
                      three non-represented Employees (the "Excluded
                      Employees")) with base pay equal to base pay with Seller
                      immediately prior to the Closing Date and total
                      compensation and benefits comparable in the aggregate for
                      all Employees taken as a whole to total compensation and
                      benefits (based solely on the plans and programs
                      identified on Schedule M) provided by Seller on the date
                      hereof (such Employees who accept offers of employment
                      being the "Transferred Employees"); provided, however,
                      that Buyer shall have no obligation to maintain any
                      specific plan, program or arrangement of Seller. Nothing
                      herein shall (i) require Buyer to offer employment to any
                      person on long or short term disability, layoff or leave
                      of absence (other than FMLA), or (ii) restrict or limit
                      Buyer's ability to terminate the employment of any
                      Transferred Employee for any reason at any time; provided,
                      however, Buyer shall offer employment to any Employees on
                      short or long term disability who is able to return to
                      work within one year of the Closing Date, and if any such
                      Employee accepts such offer and returns to work, Buyer and
                      Seller shall treat such Employees as Transferred Employees
                      hereunder. Buyer further agrees that it will provide
                      severance and related benefits to any non-represented
                      Employees who are later terminated by Buyer, other than
                      for cause, from employment with the Refinery or Buyer
                      within twelve months after the Closing Date under a plan
                      which contains the same benefit levels as the BP Oil
                      Company Lima Refinery 1996 Separation Program (summary
                      attached as Schedule N.) provided, however, that Seller
                      shall reimburse Buyer for one-half of Bpaid or provided to
                      or for the benefit of any such non-represented Employees
                      or their dependents separated from employment with the
                      Buyer within twelve months of the Closing Date. Seller
                      agrees that it shall work in good faith with Buyer to
                      assist Buyer to employ and retain the Employees it has
                      offered employment to and Seller shall not discourage such
                      Employees from accepting Buyer's offer of employment. The
                      Excluded Employees will be made available to Buyer by
                      Seller for a specified period following the Closing Date
                      through individual contractual arrangements to be
                      finalized on or before the Closing Date;

               (ii)   Each Transferred Employee shall be eligible to enroll in
                      Buyer's new or existing medical and dental plans or HMOs
                      which coverage shall be effective on a date which is the
                      first day of the month coincident with, or next following
                      the Closing Date.

                      Buyer shall reimburse Seller for Seller's employer
                      contribution made on behalf of each Employee who accepted
                      Buyer's offer for any coverage by Seller between the
                      Closing Date and the effective date of Buyer's coverage.
                      Seller's medical and dental plans shall be liable for
                      covered expenses of the Employees (and covered dependents)
                      for medical and dental services provided through the last
                      day of the month in which the Closing occurs. Any
                      exclusions and benefit conditions for pre-existing
                      conditions under the terms of the Buyer's medical and
                      dental plans (and HMOs, if any) shall not apply if
                      comparable exclusions and limitations did not apply to
                      Employees, dependents or conditions immediately prior to
                      the effective date of Buyer's coverage under the Seller's
                      medical and dental plans or any applicable HMO (the "BPA

               (iv)   With respect to the BP America Retirement Accumulation
                      Plan (the "RAP") and (subject to the provisions of Section
                      12.D.) the BP America Master Hourly Plan for Represented
                      Employees ("MHP"), plan sponsorship shall be retained by
                      Seller Group and the active participation of the
                      Transferred Employees shall cease as of the Closing Date.
                      Seller shall fully vest such Transferred Employees in
                      their benefits accrued as of the Closing Date under the

                      90 days of the Closing Date, effective as of the Closing
                      Date the accrued benefit liabilities and related assets
                      pertaining to the represented Transferred Employees under
                      the MHP shall be transferred in a manner complying with
                      Code Sections 411(d)(6) and 414(l) to a separate qualified
                      plan to be maintained by Buyer (the "Mirror Plan"). The
                      calculation of the value of the assets to be transferred
                      shall be made by Seller's actuary in accordance with the
                      actuarial assumptions in the attached Schedule O and
                      reviewed by Buyer's actuary and shall equal the sum of (1)
                      and (2) where (1) equals the accumulated benefit
                      obligation (the "ABO") and (2) equals one-half of the
                      excess of the projected benefit obligation over the ABO,
                      determined as of the Closing Date of the represented
                      Transferred Employees participating in the MHP as of the
                      Closing Date (the "Represented Employees") decreased for
                      benefit payments made after the Closing Date and before

                      the Represented Employees (the "Transfer Amount"). The
                      Transfer Amount shall accrue interest from the Closing
                      Date to the transfer date at a rate equal to the one-year
                      Treasury bill rate as of the Closing Date. The Transfer
                      Amount shall be transferred hereunder in the form of cash
                      or cash equivalents. The Mirror Plan and its related trust
                      shall be reasonably satisfactory to Sellers and its

                      further shall provide Sellers with such reasonable
                      assurances as Seller shall request of such tax-qualified
                      status prior to the transfer of assets and liabilities.
                      Sellers shall provide Buyer with such reasonable
                      assurances as Buyer shall request of the tax qualified
                      status of the MHP immediately prior to the transfer of

                      within a reasonable period after all requirements of this
                      Section 12.B.(ii) have been met. The Mirror Plan shall

                      liabilities and related assets pertaining to the account
                      balances of the Transferred Employees under such plans
                      shall be transferred within a reasonable time (i.e.,
                      approximately 120 days) after the Closing Date (the
                      "Transfer Date") in a manner complying with Code Sections
                      411 (d) (6) and 414 (l) to separate qualified plans to be

                      Plans, in cash, the liquidation value of the aggregate

                      through the Closing Date and all earnings accrued as of
                      the Transfer Date but excluding any distributions or
                      withdrawals to the Transfer Date) received in order to

                      Seller shall request of such tax-qualified status prior to
                      the transfer of assets and liabilities. Seller shall

                      5310-A with respect to the transfer at least thirty days
                      prior thereto. The Mirror Savings Plans shall vest the
                      Employees in their account balances as of the Transfer
                      Date;

               (vi)   From and after the Closing Date, the Employees shall be
                      given credit for their service recognized by Seller prior
                      to the Closing Date for purposes of eligibility and
                      vesting under all applicable plans and programs of Buyer
                      and, after the asset transfers described in Sections
                      12.B.(iv) (if any) and (v) above, benefit accruals under
                      the Mirror Plan and benefit service under the Mirror

                      life insurance coverage to retirees former or current
                      employees under the Benefit Plans. Nor shall Buyer be
                      responsible for any of Seller's obligations under any of
                      non qualified, excess or supplemental pension benefit
                      plans or any other liabilities related to the Benefits
                      Plans which Buyer has not explicitly assumed herein.

          C.   Resignees. Approximately 35 Employees whose names will be
               provided by Seller to Buyer had indicated an intention to Seller
               to cease employment at the Refinery following Seller's previous
               announcement of a planned Refinery closure (the "Resignees").
               Buyer may retain any or all such Resignees in its employment
               provided, however, Buyer must offer each such Resignee the option
               to terminate employment on or before December 31, 1999, in which
               case Buyer shall make payments to and provide benefits for the
               Resignees on account of such resignation in accordance with
               Schedule N, and Seller shall reimburse Buyer for its costs and
               expenses in providing such benefits (excluding administrative
               costs). The Resignees will be required to give ninety days notice
               of their intention to accept such option to terminate employment.
               Any Resignee who is employed or works as a contract worker after
               December 31, 1999 will not be entitled to any payment funded by
               Seller under this provision. The Buyer agrees that if it employs
               or re-employs any Resignee either as an employee or as a contract
               worker for a period of one year following the Resignee's
               termination date with either the Seller or the Buyer, then Buyer
               will reimburse the Seller for an amount equal to any benefits
               provided and amounts paid by Seller for such Resignee under the
               applicable

               12. Buyer and Seller shall not, without consent of the other,
               employ or offer employment to any employees of the other in Ohio
               for a period ending one year following Closing. During this
               period the Buyer and Seller will develop a mutually satisfactory
               protocol concerning recruitment and retention of personnel and
               recognizing BPC's need to offer employment to Refinery employees
               in order to fill up to 15 positions at its planned BDO Plant
               within forty-five days of Closing and, subject to the foregoing,
               Buyer's need to have appropriate employees to run the operations
               of the Refinery.

          E.   Successorship. The Buyer shall recognize the Oil, Chemical and
               Atomic Workers International Union and its Local 7-624 as the
               exclusive representative of the Represented Employees in the
               Plant Unit and the Clerical Unit and shall adopt the Collective
               Bargaining Agreements and all existing Memoranda of Agreements
               currently in existence between the Seller and the Union. Such
               Collective Bargaining Agreements shall remain in full force and
               effect for their duration, except for mutually agreed to changes,
               and continued employment with the Buyer shall not require any
               form of a severance payment from the Seller. If requested by the
               Union, the Buyer shall negotiate with the Union in good faith
               regarding benefits.

          F.   WARN Act. The Seller shall not effect a "plant closing" or "mass
               layoff" as those terms are defined in the Worker Adjustment and
               Retaining Notification Act ("WARN"), affecting in whole or in
               part any site of employment, facility, operating unit or employee
               of the Refinery, with respect to the Refinery business, without
               notifying the Buyer in advance and obtaining the advance approval
               of the Buyer, and complying with all provisions of WARN.
               Notwithstanding anything to the contrary herein, Seller makes no
               warranty under this paragraph with respect to consummation of the
               transactions contemplated hereby.

          13.  BUYER'S OBLIGATION TO CLOSE. Buyer's obligation to Close under

               instituted by any federal, state or foreign governmental agency
               to restrain, prohibit, otherwise interfere with or obtain

               documents and to take or cause to be taken such further actions
               as the other party may from time to time reasonably request in
               order to confirm or carry out the transactions and obligations
               contemplated in this Agreement. No such instrument or document
               shall expand a party's liability beyond that contemplated in this
               Agreement.

          B.   BDO Plant. Subject to the terms of this Section 15.B., BPC will
               have the right to construct a 1:4 Butanediol Plant (the "BDO
               Plant") at the Refinery. After the Closing, BPC and Buyer will
               negotiate in good faith the form of appropriate BDO Plant
               agreements in time to allow construction of a BDO Plant to start
               in November 1998.

                    the Refinery for the project with independent access and
                    with rail proximity. The specific location of such land will
                    be determined by mutual agreement of BPC and Buyer and must
                    be acceptable to both parties. This land will either be
                    retained, net leased to BPC or deeded to BPC as BPC and
                    Buyer shall mutually agree. The purchase price for the land
                    will be $1 and BPC will receive such land on an "as is,
                    where is" basis without any representation, warranties,

                      arising out of or relating to Buyer's ownership of such
                      land including environmental liabilities.

               (ii)   Butane - BPC anticipates that the BDO Plant will require a
                      supply of approximately 47 million gallons per year of
                      high-purity n-butane for the BDO Plant. Within one (1)
                      month of the Closing Date, Buyer will provide BP with a
                      specific proposal acceptable to Buyer to permit BP to
                      import and store the high-purity n-butane material on-site
                      (subject to available storage capacity) in time for the
                      BDO Plant to operate by December 31, 1999, on BPC's
                      schedule. At Buyer's option, BPC and Buyer will negotiate
                      for a supply of high-purity n-butane on terms acceptable
                      to both parties.

               (iii)  Key Utilities - The BDO Plant is a substantial steam
                      generator (estimated - 1,300 million lb./yr. HP Steam) and
                      BPC and the Buyer will negotiate with a view to achieving
                      the efficient and economic energy integration with the
                      Refinery on mutually acceptable terms. The BDO Plant may
                      also be able to provide surplus hydrogen for Refinery use
                      on mutually acceptable terms.

               (iv)   Equipment Re-Use/Sharing - It had been intended to re-use
                      various items of redundant Refinery equipment in the BDO
                      Plant e.g. Butane storage. BPC is prepared to discuss
                      arrangements including re-purchase, lease or operation
                      arrangements for such items with the Buyer, it being
                      understood that neither BPC nor Buyer is obligated to
                      enter into any such arrangement.

               (v)    Permits - BPC has an active permit application for the BDO
                      Plant which relies on Refinery shutdown emission credits
                      which shall no longer be available to BPC. BPC believes
                      there are specific opportunities (eg. CO boiler and steam
                      boilers) for reduction of Refinery emissions, either by
                      closure or improvement, which may allow an expedited
                      revised BDO Plant filing and which would not adversely
                      affect the Refinery. The Buyer agrees to work actively
                      with BPC to identify, within one (1) month of the Closing
                      Date, whether there are any low cost emission reductions
                      that do not adversely impact the Refinery and that can be
                      funded and made on terms acceptable to BPC and Buyer. BPC
                      would fund any agreed Refinery plant improvements to
                      facilitate the implementation of these reductions in
                      exchange for the associated emissions credits.

                    contribution under CERCLA, breaches of statutory or implied
                    warranties or otherwise, nuisance or other tort actions, and
                    common law rights of contribution. Anything in this
                    Agreement to the contrary notwithstanding, Seller's sole and
                    exclusive remedy for breach of this Agreement by Buyer prior
                    to Closing shall be the termination of this Agreement to the
                    extent permitted by Section 19. and the retention of the
                    Deposit as provided for in Section 3.(A).

               (ii) Dispute Resolution. If a dispute arises between the parties
                    pursuant to the provisions of Section 8 and that dispute
                    cannot be resolved within a reasonable period of time,
                    either party hereto may notify the other party that the
                    dispute is to be submitted to arbitration, such arbitrations
                    to be held in Chicago, Illinois. In the event that notice of
                    submission of the dispute to arbitration is provided by
                    either party, the parties jointly shall select an
                    environmental consultant or engineer who has not rendered
                    service to such party or any of its Affiliates during the
                    previous three years and is reasonably qualified (including
                    at least 7 years' experience in the field) to arbitrate such
                    dispute (the "Independent Consultant"). Where the amount in
                    dispute exceeds $1 million, each side shall select an
                    Independent Consultant, and the two Independent Consultants
                    shall jointly select a third. The three Independent
                    Consultants shall hear and resolve the dispute.
                    Notwithstanding any other provision of the Agreement, the
                    parties shall each bear one-half of the cost of the
                    Independent Consultant(s). If the parties cannot agree on an
                    Independent Consultant, they shall apply to the American
                    Arbitration Association for the appointment of an
                    Independent Consultant qualified as described above. The
                    Independent Consultant(s) shall establish an expedited
                    procedure for hearing and resolving the dispute. Such
                    procedure shall include provision that the Independent
                    Consultant(s) shall be required to order each party to
                    propose a resolution of the matter. Unless

                    the parties hereto agree otherwise, the Independent
                    Consultant(s) shall be required to render a decision
                    resolving the dispute, with a written opinion stating the
                    reasons therefor, no more than 60 days after the Independent
                    Consultant is retained. The decision of the Independent
                    Consultant shall be final and binding and a court of
                    competent jurisdiction may enter judgment thereon. The

                    hereto with respect to any disputes arising out of Section
                    8.;

          E.   General Provisions. In the case of any claim brought under
               Sections 8 or 16., sometimes referred to as a claim for
               "Indemnification".

               (i)  The party entitled to Indemnification (the "Indemnified
                    Party") shall notify the party obligated to provide
                    Indemnification (the "Indemnifying Party") with reasonable
                    promptness of its discovery of any matter giving rise to
                    such claim, provided that failure to so notify will not
                    release the Indemnifying Party from liability except to the
                    extent such party is materially adversely affected by such
                    delay;

               (ii) With respect to any third-party claim or action, or need for
                    Corrective Action pursuant to Section 8., the Indemnifying
                    Party shall, except as otherwise provided herein, be
                    entitled to assume the defense thereof with counsel, the
                    fees and expenses of which shall be paid by the Indemnifying
                    Party, reasonably satisfactory to the Indemnified Party; and
                    subsequent to such assumption of defense, the Indemnifying
                    Party shall not be liable to the Indemnified Party for any
                    fees or expenses of counsel subsequently incurred by the
                    Indemnified Party in connection with the defense thereof,
                    provided that an Indemnified Party shall have the right to
                    retain its own counsel, but the fees and expenses of such
                    counsel shall be at the expense of such Indemnified Party
                    unless (i) the Indemnifying Party and the Indemnified Party
                    shall have mutually agreed to the retention of such counsel
                    or (ii) the named parties to any such proceeding (including
                    any impleaded parties) include both the Indemnifying Party
                    and the Indemnified Party and representation of both parties
                    by the same counsel would be inappropriate due to actual or
                    potential differing interests between them. The Indemnifying
                    Party shall not, in connection with any proceeding or
                    related proceedings, be liable for the reasonable fees and
                    expenses of more than one such firm for all such Indemnified
                    Parties. The Indemnifying Party will not settle or
                    compromise any third party claim unless such settlement or
                    compromise involves solely the payment of money by the
                    Indemnifying Party and such settlement or compromise
                    includes as an unconditional term

                    thereof the giving by the claimant of a release of the
                    Indemnified Party from all liability with respect to the
                    matters relating to such claim and does not involve any
                    admission of culpability;

              (iii) The Indemnified Party and the Indemnifying Party will each
                    provide the other full cooperation in the defense of any
                    such action, and shall furnish any documents or endeavor to
                    make available any witnesses under its control;

               (iv) Except with respect to third-party claims or actions, any
                    recovery from the Indemnifying Party shall be limited to the
                    actual direct Losses, and shall not include punitive
                    damages, consequential damages, lost profits or rents,
                    diminution in the value of real property or business
                    interruption losses incurred by the Indemnified Party;

               (v)  A Buyer Indemnified Party shall not be entitled to make a
                    claim against Seller under paragraph A.(ii) of this
                    Section 16. unless and until (a) Buyer shall have provided
                    Seller written notice of such default; and (b) Seller shall
                    have failed to cure such default within thirty (30) days
                    after Seller's receipt of Buyer's notice; and

               (vi) A Seller Indemnified Party shall not be entitled to make a
                    claim against Buyer under paragraph B.(ii) of this Section
                    16. unless and until (a) Seller shall have provided Buyer
                    written notice of default; and (b) Buyer shall have failed
                    to cure such default within thirty (30) days after Buyer's
                    receipt of Seller's notice.

          F.   Attorney's Fees. In connection with any litigation arising out of
               this Agreement or to enforce any claim pursuant to Sections 8 or
               16. hereof, the prevailing party shall be entitled to recover
               from the nonprevailing party its reasonable attorney's fees and
               costs, on appeal or otherwise.

          G.   Time Limitation. Any claim under Section 16.A.(ii)(y), or

               Agreement or the transactions contemplated hereunder for breach
               of warranty shall be brought within one year after the Closing
               Date. Any claim under 16.B.(ii)(x) for Indemnity arising under or

               for breach of Section 11.B shall be brought within one year after
               the Closing Date, unless prior to such breach Seller had
               knowledge of the action to be taken resulting in the breach, in
               which event this limitation shall not apply. Any claim under
               Section 8. or Section 16.B.(v), (vi) or (vii) for Indemnity (in
               each case except to the extent relating to any Waste Unit) shall

               (17) years after the Closing Date. A claim shall be deemed to
               have been brought only upon delivery of a written notice to the
               other party (which notice may consist of a notice of breach
               pursuant to paragraph E.(v) of this Section 16.) at the notice
               address set forth in Section 20., stating with reasonable
               specificity the basis for the claim. Any claim required to be
               made within such one or seventeen year period not so timely made
               will be forever barred. This provision shall not be deemed to
               limit any claims or rights to Indemnification for third party
               claims or pursuant to Sections 16.A.(i), 16.A.(iii), 16.B.(i) or
               16.B.(ii)(x), (other than as provided above with respect to
               Section 11.B), 16.B.(ii) or 16.B.(iv).

          H.   Monetary Limitation. The Buyer shall have no claim under Section
               16.B.(ii)(y) or (except in the circumstances described in the
               following sentence) under 16.B.(ii)(x) with respect to a breach
               of Section 11.B. against Seller for any Losses unless and until
               the aggregate of all such Losses incurred or sustained by the
               Buyer exceeds Three Million Five Hundred Thousand Dollars
               ($3,500,000.00) and then only for the excess over Three Million
               Five Hundred Thousand Dollars ($3,500,000.00) (the "Threshold").
               Claims under Section 16.B.(ii)(x) with respect to a breach of
               Section 11.B. shall not be subject to or be counted for purposes
               of the preceding sentence if Seller had knowledge of the action
               to be taken resulting in the breach, in which event the
               limitation in the preceding sentence shall not apply. After the
               Threshold has been reached, Seller shall have no obligation to
               Indemnify the Buyer Indemnified Parties under this Section 16
               with respect to matters subject to the limitations contained in
               the first sentence of this Section 16.H for any Losses amounting
               to less than Fifty Thousand Dollars ($50,000.00) in the aggregate
               arising out of the same occurrence or matter. The monetary
               limitations in this Section 16.H. will not apply to any Losses
               arising pursuant to the provisions of Section 8. The provisions
               of this Section 16.H. and of 16.I. shall not apply to any breach
               of the last sentence of Section 7.G.

          I.   Limitation of Liability. Seller's aggregate liability for
               Indemnification pursuant to Section 16.B.(ii)(y), or under
               Section 16.B.(ii)(x) with respect to a breach of Section 11.B. in
               circumstances where Seller did not have knowledge, prior to the
               breach, of action taken that resulted in the breach of Section
               11.B, shall in no event exceed an amount equal to Twenty Five
               Million Dollars ($25,000,000.00). This provision shall not limit
               Seller's liability for Excluded Liabilities or for Losses
               pursuant to the provisions of Section 8.

          J.   Purchase Price Adjustment. Any Indemnity payments made hereunder
               will be treated by the parties on their Tax Returns as an
               adjustment to the Purchase Price.

          A.   All real estate transfer taxes will be paid 50% by the Buyer and

               contemplated hereby, including conveyance, documentary, stamp and
               recording taxes or charges, (but in no event including Taxes
               computed on the basis of Seller's income which shall be borne by
               Seller) shall be borne 50% by Buyer and 50% by Seller. In the
               event that one party pays any taxes covered under this Section
               17, the other party shall reimburse the paying party for 50%
               thereof immediately upon receipt of written notice of such
               payment. In the event the use by Buyer of any of the Refinery
               qualifies for exemption from otherwise applicable taxes covered
               under this Section 17, Buyer and Seller shall provide all
               appropriate exemption certifications in support of such
               exemption.

          B.   All real and personal property taxes and assessments and water,
               utility, lease, sewage and similar charges of the Refinery will
               be prorated as of the Closing Date.

          18. RECORDS/LITIGATION ASSISTANCE.

          A.   All the books and records at the Refinery other than tax,
               financial records, Excluded Assets and Excluded Information (as
               defined in Exhibit 3) (the "Records") will remain at the Refinery
               after the Closing Date. Seller and its accountants and agents
               shall have reasonable access to the Records related to the period
               up to and including the Closing Date and Buyer shall notify
               Seller at least thirty (30) days prior to the disposition of any
               portion thereof for ten (10) years from the Closing Date unless
               during that period Seller notifies Buyer of an audit by the
               federal, state, or local tax or revenue authorities to which any
               Records pertain, in which case access to such Records will be
               permitted until such time as Buyer is notified of the conclusion
               of the audit proceeding, and shall allow Seller to take the
               originals or copies thereof. While the Records are in Seller's
               possession, Buyer shall be allowed reasonable access thereto.

          B.   After the Closing Date, each party will provide such assistance
               as the other parties may from time to time reasonably request in
               connection with the preparation of Tax Returns required to be
               filed, any audit or other examination by any taxing authority,
               any judicial or administrative proceeding relating to liability
               for taxes, or any claim for refund in respect of such Taxes or in
               connection with any litigation and proceedings or liabilities
               related to the Refinery including making available employees for
               interviews, litigation preparation and testimony.

               The requesting party will reimburse the assisting party for the
               out-of-pocket costs incurred by the assisting party.

          19. TERMINATION RIGHTS.

          A.   This Agreement may be terminated at any time prior to the Closing
               Date as follows and in no other manner:

               (i)  By mutual consent of Buyer and Seller;

               (ii) By either party, if not then in breach of this Agreement, if
                    the other party is in material breach of this Agreement so
                    that the conditions set forth in Section 13 or 14 will not
                    be capable of being satisfied if such breach continues and
                    such breach remains uncured 30 days after written notice
                    from the non-breaching party; or

              (iii) By Buyer if a Deposit Return Event occurs.

          B.   If this Agreement is terminated by mutual consent or other than
               by reason of a party's default, then neither party shall have a
               claim for damages as a result of the termination. A party
               rightfully terminating this Agreement as a result of the other
               party's material breach shall retain any claim it may have for
               damages arising from such breach.

          20. INLAND SYSTEM. BP Pipelines owns shares in the Inland Corporation
("Inland"), an Ohio corporation which transports petroleum products in the State
of Ohio for the owners of Inland. BP Pipelines currently operates all pipelines
owned by Inland ("Inland System") and the Refinery is connected to six of BP
Pipelines product pipelines to the Inland Mainfold which in turn, connect to the
Inland System. Buyer acknowledges that the Inland System is a private pipeline
system which provides transportation services only to its owners; is not a
common carrier; and is not regulated by the Public Utilities Commission of Ohio
("PUCO") or the Federal Energy Regulatory Commission ("FERC"). Further, Buyer
acknowledges that Buyer has no right to transport petroleum products on or
through the Inland System. Buyer agrees to take no action or inspire or assist
another party in any action which: challenges the private status of the Inland
System; attempts to have the Inland System deemed to be a common carrier; or
attempts to subject the Inland System to regulation by the PUCO or the FERC. BP
Pipelines will permit Buyer's use, without charge, of any piping connection to
the Inland System which is retained by Seller for delivery of petroleum products
to any owner of Inland.

          21. Change of Ownership. In addition to the obligations imposed on
Buyer pursuant to Section 8.D., Buyer will advise Seller should it decide to
sell or exchange the Refinery or all or substantially all of the assets acquired
hereunder to an unaffiliated entity or entities in order that Seller can discuss
its potential involvement in such a sale or exchange.

          25. GENERAL.

          A.   This Agreement, the attached schedules and exhibits and the
               agreements referred to herein or executed simultaneously, set
               forth the entire agreement and understanding of the parties in
               respect to the transactions contemplated hereby and supersede all
               prior agreements, arrangements and undertakings relating to the
               subject matter hereof (other than the Confidentiality Agreement).
               No representation, promise, inducement or
<PAGE>


                                                                              52


               statement of intention has been made by any party which is not
               embodied in or superseded by this Agreement or the
               Confidentiality Agreement or in the documents referred to herein,
               and no party shall be bound by or liable for any alleged
               representation, promise, inducement or statement of intention not
               so set forth whether in the Confidential Information Memorandum
               for the Refinery or otherwise. Buyer's obligations under the
               Confidentiality Agreement shall not survive the Closing.

          B.   All of the terms, covenants, representations, warranties and
               conditions of this Agreement shall be binding upon, and inure to
               the benefit of, and be enforceable by, the parties hereto and
               their respective successors, heirs, and other legal
               representatives. This Agreement and the rights and obligation
               hereunder shall not be assigned by any party hereto except that
               either party may assign its rights and duties to any affiliate
               provided that the assigning party shall remain liable for any
               such affiliate's duties, obligations and/or liabilities
               hereunder, provided that with the prior written consent of Seller
               (which consent will not be unreasonably withheld or delayed)
               after the Closing Buyer may assign its rights and obligations
               under this Agreement and (as to future obligations only) be
               released therefrom to any purchaser of all or substantially all
               of the assets of the Refinery. For purposes of the immediately
               preceding proviso, Seller's withholding of consent will be deemed
               unreasonable unless the financial strength or operating
               capability of the proposed purchaser is reasonably expected to
               increase Seller's liability or costs hereunder, or materially and
               adversely affect Seller's ability to realize on the
               Indemnification provided to Seller under Sections 8. and 16.
               Competitive considerations will not enter into Seller's
               assessment.

          C.   This Agreement may be amended, modified, superseded or canceled,
               and any of the terms, covenants, representations, warranties or
               conditions hereof may be waived, only by a written instrument
               executed by the parties hereto, or, in the case of a waiver, by
               or on behalf of the party waiving compliance. The failure of any
               party at any time or times to require performance of any
               provision hereof shall in no manner affect the right at a later
               time to enforce the same. No waiver by any party of any
               condition, or of any breach of any term, covenant, representation
               or warranty contained in this Agreement, in any one or more
               instances, shall be deemed to be or construed as a further or
               continuing wavier of any such condition or breach or a waiver of
               any other condition or of any breach of any other term, covenant,
               representation or warranty.

          D.   The section or paragraph headings contained in this Agreement are
               for convenient reference only, and shall not in any way affect
               the meaning or interpretation of this Agreement. This Agreement
               may be executed

                                                                              53


               simultaneously in two or more counterparts, each of which shall
               be deemed an original, but all of which shall constitute but one.

          E.   Unless the context requires otherwise:

               (i)  this Agreement includes this Asset Purchase Agreement and
                    any other Agreement entered into by Buyer and Seller on the
                    Closing Date (the "Related Agreements");

               (ii) the singular shall include the plural and the plural shall
                    include the singular and any gender shall include all other
                    genders all as the meaning and the context of the Agreement
                    shall require;

              (iii) references to Sections refers to sections of this Agreement;

               (iv) references to Exhibits and Schedules are to exhibits and
                    schedules attached to this Agreement, each of which is made
                    a part of this Agreement for all purposes; and

               (v)  the word "including" means "including without limitation."

          F.   All representations and warranties of Seller hereunder are given
               jointly and severally by each of BPO, Standard, BP Pipelines and
               BPC and each of BPO, Standard, BP Pipelines and BPC shall be
               jointly and severally liable for all obligations of Seller
               hereunder.

          26. NO THIRD PARTY BENEFICIARIES. Except as provided in Sections 8..
and 16. with respect to Indemnification of Indemnified parties hereunder,
nothing in this Agreement shall confer any rights upon any person or entity
other than the parties hereto and their respective heirs, successors and
permitted assigns.

          27. DEFINITION OF AFFILIATE. As used herein, the term "affiliate"
shall have the meaning set forth in Rule 405 promulgated under the Securities
Act of 1933, as amended,

     16.  Indemnification

     G.   Time Limitation. Any claim under Section 16.A.(ii)(y), or
          16.B.(ii)(y), for Indemnity arising under or out of this Agreement or
          the transactions contemplated hereunder (other than a breach of
          Section 8, which will be subject to the 17 year time limitation set
          forth below) for breach of warranty shall be brought within one year
          after the Closing Date. Any claim under Section 16.B.(ii)(x) for
          Indemnity arising under or out of this Agreement or the transactions
          contemplated hereunder for breach of Section 11.B. shall be brought
          within one year after the Closing Date, unless prior to such breach
          Seller had knowledge of the action to be taken resulting in the
          breach, in which event this limitation shall not apply. Any claim
          under Section 8. or Section 16.B.(v), (vi) or (vii) for Indemnity (in
          each case except to the extent relating to any Waste Unit) shall be
          brought within seventeen (17) years after the Closing Date. a claim
          shall be deemed to have been brought only upon delivery of a written
          notice to the other party (which notice may consist of a notice of
          breach pursuant to paragraph E.(v) of this Section 16.) at the notice
          address set forth in Section 20., stating with reasonable specificity
          the basis for the claim. Any claim required to be made within such one
          or seventeen year
<PAGE>
                                                                               3

 

          period not so timely made will be forever barred. This provision shall
          not be deemed to limit any claims or rights to Indemnification for
          third party claims or pursuant to Sections 16.A.(i), 16.A.(iii),
          16.B.(i) or 16.B.(ii)(x), (other than as provided above with respect
          to Section 11.B), 16.B.(ii) or 16.B.(iv).

     H.   Monetary Limitation. The Buyer shall have no claim under Section
          16.B.(ii)(y) or (except in the circumstances described in the
          following sentence) under Section 16.B.(ii)(x) with respect to a
          breach of Section 11.B. against Seller for any Losses unless and until
          the aggregate of all such Losses incurred or sustained by the Buyer
          exceeds Three Million Five Hundred Thousand Dollars ($3,500,000.00)
          and then only for the excess over Three Million Five Hundred Thousand
          Dollars ($3,500,000.00) (the "Threshold"). Claims under Section
          16.B.(ii)(x) with respect to a breach of Section 11.B. shall not be
          subject to or be counted for purposes of the preceding sentence if
          Seller had knowledge of the action to be taken resulting in the
          breach, in which event the limitation in the preceding sentence shall
          not apply. After the Threshold has been reached, Seller shall have no
          obligation to Indemnify the Buyer Indemnified Parties under this
          Section 16. with respect to matters subject to the limitations
          contained in the first sentence of this Section 16.H. for any Losses
          amounting to less than Fifty Thousand Dollars ($50,000.00) in the
          aggregate arising out of the same occurrence or matter. The monetary
          limitations in this Section 16.H. will not apply to any Losses arising
          pursuant to the provisions of Section 8. or out of a breach of
          representation or warranty contained in Section 8. The provisions of
          this Section 16.H. and of 16.I. shall not apply to any breach of the
          last sentence of Section 7.G.

     I.   Limitation of Liability. Seller's aggregate liability for
          Indemnification pursuant to Section 16.B.(ii)(y), or under Section
          16.B(ii)(x) with respect to a breach of Section 11.B. in circumstances
          where Seller did not have knowledge, prior to the breach, of action
          taken that resulted in the breach of Section 11.B. shall in no event
          exceed an amount equal to Twenty Five Million Dollars
          ($25,000,000.00). This provision shall not limit Seller's liability
          for Excluded Liabilities or for Losses pursuant to the provisions of
          Section 8 or out of a breach of representation or warranty contained
          in Section 8.

5.   Amendment of Section 25.B.

     Section 25.B. of the Agreement is hereby amended to read, in its entirety,
     as follows:

     B.   All of the terms, covenants, representations, warranties and
          conditions of this Agreement shall be binding upon, and inure to the
          benefit of, and be enforceable by, the parties hereto and their
          respective successors, heirs, and other legal representatives. This
          Agreement and the rights and obligation hereunder shall not be
          assigned by any party hereto except that either party may assign its
          rights and duties to any affiliate provided that the assigning party
          shall remain liable for any such affiliate's duties, obligations
          and/or
<PAGE>
                                                                               4

 

          liabilities hereunder, provided that with the prior written consent of
          Seller (which consent will not be unreasonably withheld or delayed)
          after the Closing Buyer may assign its rights and obligations under
          this Agreement and (as to future obligations only) be released
          therefrom to any purchaser of all or substantially all of the assets
          of the Refinery. For purposes of the immediately preceding proviso,
          Seller's withholding of consent will be deemed unreasonable unless the
          financial strength or operating capability of the proposed purchaser
          is reasonably expected to increase Seller's liability or costs
          hereunder, or materially and adversely affect Seller's ability to
          realize on the Indemnification provided to Seller under Sections 8.
          and 16. Competitive considerations will not enter into Seller's
          assessment.

          Notwithstanding anything to the contrary herein, Seller shall have the
          right to assign this Agreement, in whole or in part, to an
          intermediary party for purposes of completing a like-kind exchange of
          properties pursuant to Section 1031 of the Code. The parties
          understand that the Seller desires to receive "replacement property"
          (as that term is defined in Treasury Reg. (S)1.103(k)-
          1(a))("Replacement Property") in full or partial exchange for the
          Purchased Assets in a like-kind exchange under Section 1031 of the
          Code if suitable Replacement Property can be identified and obtained.
          Buyer agrees to take all reasonable steps to facilitate such like-kind
          exchange, including executing any documents and instruments necessary
          to consummate such like-kind exchange, as may be reasonably requested
          by the Seller, provided that Buyer shall not be required hereby to
          incur any additional liability or unreimbursed expense. The completion
          of such like-kind exchange shall not alter the Buyer's rights
          hereunder and Buyer shall have no obligation to find, select or obtain
          any Replacement Property.

6.   Except as amended herein, and as provided in the letter from Clark dated 20
     July 98 titled Resolution Of Due Diligence Issues, the Agreement remains in
     full force and effect.

In witness whereof, the parties have duly executed this instrument the day and
year first above written.
