<PAGE>

          (c) Seller shall deliver to Refinery Buyer on or prior to the second
Business Day preceding the Closing Date a statement (the "Adjustment Statement")
setting forth Seller's preliminary determination (the "Initial Adjustment
Amount") of the Adjustment Amount. The "Adjustment Amount" shall be the
algebraic sum of:

          (i) a negative amount equal to Seller's pro rata share of Property
     Taxes for the Current Tax Period in accordance with Section 12.1,

          (ii) a positive amount equal to the aggregate amount of any credits
     for payments made by Seller prior to Closing for which Seller is entitled
     to a credit pursuant to Section 3.4, and

          (iii) a negative amount equal to the aggregate amount of any credits
     for amounts paid to Seller prior to Closing for which Refinery Buyer is
     entitled to a credit pursuant to Section 3.4.

If the Initial Adjustment Amount shown on the Adjustment Statement is a positive
number, then the Base Purchase Price shall be increased by such amount, and if
the Initial Adjustment Amount shown on the Adjustment Statement is a negative
number, then the Base Purchase Price shall be decreased by such amount, subject,
in each case, to adjustment after Closing pursuant to Section 3.5.

          Section 3.3 Purchase Price for Inventory.

          (a) Initial Valuation Statement. Seller shall deliver to Refinery
Buyer on or prior to the second Business Day preceding the Closing Date a
statement (the "Initial Valuation Statement") setting forth Seller's estimate of
the purchase price for the Inventory (the "Estimated Inventory Purchase Price"),
based on Seller's estimated volumes of Inventory to be conveyed to Refinery
Buyer and the valuation formulas set forth in SCHEDULE 3.3, PART II. Estimated
Inventory Purchase Price will be subject to adjustment following Closing based
on a physical inventory (the "Physical Inventory") commenced no more than two
(2) Business Days prior to the Closing. The Physical Inventory for the Inventory
shall be conducted in accordance with the measurement and other procedures
specified in SCHEDULE 3.3, PART I and shall be conducted by independent
inspectors, the fees and reimbursable costs of such independent inspectors to be
borne 50% by Seller and 50% by Refinery Buyer.

          (b) Subsequent Valuation Statement. Within ten (10) Business Days of
receipt of the Final Inventory Quantity Report (as provided in Section I of
SCHEDULE 3.3, PART I), Seller, shall deliver the Subsequent Valuation Statement
(defined below) to Refinery Buyer. As used herein, the "Subsequent Valuation
Statement" shall mean a statement which includes an invoice (based on the
valuation formulae set forth in SCHEDULE 3.3, PART II and the Final Inventory
Quantity and Final Inventory Quality set forth in the Final Inventory Quantity
Report) that indicates by product and in the aggregate the final purchase price
for the Inventory conveyed to Refinery Buyer pursuant hereto.

<PAGE>

          (c) Refinery Buyer Review of Subsequent Valuation Statement. Refinery
Buyer shall have ten (10) Business Days from receipt of the Subsequent Valuation
Statement to review the Subsequent Valuation Statement. During this ten (10)
Business Day period, Refinery Buyer shall be permitted to review the working
papers of Seller relating to, and shall be given access to the employee of
Seller primarily responsible for the preparation of, the Subsequent Valuation
Statement. The Subsequent Valuation Statement shall become final and binding
upon the Parties on the tenth Business Day following delivery thereof to
Refinery Buyer, unless Refinery Buyer gives written notice of its disagreement
with the Subsequent Valuation Statement ("Notice of Disagreement") to Seller
prior to such date. Any Notice of Disagreement shall (A) specify in reasonable
detail the nature of any disagreement so asserted and (B) include only
disagreements based on mathematical or typographical errors or the amount to be
paid for the Inventory not being calculated in accordance with this Section 3.3
or SCHEDULE 3.3, as the case may be. Any disagreements with or changes to the
Subsequent Valuation Statement not included in a Notice of Disagreement, as
required above, shall be waived by Refinery Buyer. If a Notice of Disagreement
is received by Seller in a timely manner, then the Subsequent Valuation
Statement (as revised in accordance with clause (A) or (B) below) shall become
final and binding upon Seller and Refinery Buyer upon the earlier of (A) the
date Seller and Refinery Buyer resolve in writing any differences they have with
respect to the matters specified in the Notice of Disagreement or (B) the date
any disputed matters specified in the Notice of Disagreement are finally
resolved in writing by the Independent Arbitrator (as defined below).
The Subsequent Valuation Statement, upon becoming final and binding in
accordance with this Section 3.3, and as the same may be revised in accordance
with the preceding clause (A) or (B), is hereinafter referred to as the "Final
Valuation Statement".

          (d) Settlement of Disputes. During the ten (10) Business Day period
following the delivery of a Notice of Disagreement, Seller and Refinery Buyer
shall seek in good faith to resolve in writing any differences which they may
have with respect to the matters specified in the Notice of Disagreement. During
such period, Seller shall have access to the working papers of Refinery Buyer
prepared in connection with its Notice of Disagreement. At the end of such ten
(10) Business Day period, Seller and Refinery Buyer shall submit to an
independent arbitrator (the "Independent Arbitrator") for review and resolution
of any and all matters which remain in dispute and which were properly included
in the Notice of Disagreement, in the form of a written brief. The Independent
Arbitrator for purposes of this Section 3.3 and Section 3.5 shall be Deloitte
Touche. The Independent Arbitrator shall make a final and binding determination
as to the submitted matters within forty-five (45) days after its appointment.
The Independent Arbitrator's determination shall be in the form of an opinion as
is appropriate under the circumstances and shall confirm that it was rendered in
accordance with this Section 3.3(d). Seller and Refinery Buyer agree that
judgment may be entered upon the determination of the Independent Arbitrator in
any court having jurisdiction over the Party against which such determination is
to be enforced. The fees and expenses of the Independent Arbitrator and the
reasonable attorney's fees and expenses of the Parties incurred in connection
with the matters submitted to the Independent Arbitrator shall be borne by
Seller and Refinery Buyer in inverse proportion as they may prevail on matters
resolved by the Independent Arbitrator, which proportionate allocations shall
also be determined by the Independent Arbitrator at the time the determination
of the Independent Arbitrator is rendered on the merits of

                                       -5-

<PAGE>

the matters submitted. Notwithstanding the foregoing, the fees and expenses of
Seller incurred in connection with its preparation of the Subsequent Valuation
Statement and its review of the Notice of Disagreement shall by borne by Seller,
and the fees and expenses of Refinery Buyer incurred in connection with its
review of the Subsequent Valuation Statement and the preparation of any Notice
of Disagreement shall be borne by Refinery Buyer.

          (e) Final Payment. If the amounts indicated in the Final Valuation
Statement are, in the aggregate, more than the Estimated Inventory Purchase
Price, Refinery Buyer shall, within ten (10) days after the Subsequent Valuation
Statement becomes final and binding pursuant to this Section 3.3, make payment
to Seller by wire transfer in immediately available funds of the amount of such
difference not otherwise paid by Refinery Buyer and, if not paid by 12:00 noon
Central Time on the last day of said 10-day period, together with interest
thereon at a rate equal to the Agreed Rate from and including the last day of
said 10-day period to but excluding the date of payment if paid by 12:00 noon
Central Time. If the amounts indicated in the Final Valuation Statement are, in
the aggregate, less than the Estimated Inventory Purchase Price, Seller shall,
within ten (10) days after the Subsequent Valuation Statement becomes final and
binding pursuant to this Section 3.3, make payment to Refinery Buyer by wire
transfer in immediately available funds of the amount of such difference
overpaid by Refinery Buyer and, if not paid by 12:00 noon Central Time on the
last day of said 10-day period, together with interest thereon at a rate equal
to the Agreed Rate from and including the last day of said 10-day period to but
excluding the date of payment if paid by 12:00 noon Central Time. Either party
may elect, at any time in advance of the Subsequent Valuation Statement becoming
final and binding, to pay to the other party any portion which is not in dispute
of such difference between the Estimated Inventory Purchase Price and the
amount(s) in the Subsequent Valuation Statement.

          Section 3.4 Prepayments.

          (i) If, prior to Closing, Seller pays any license fees, tariffs,
     rentals, service fees, payments for utilities, payments for Inventory, or
     other similar obligations with respect to the Assets or Seller's Business
     which under GAAP are attributable, in whole or in part, to the period after
     the Closing Date, Seller shall be entitled to a credit in the Adjustment
     Amount with respect to the portion thereof which under GAAP is attributable
     to the period after the Closing Date; provided that, Seller shall not be
     entitled to a credit under this Section for the prepayment of any accounts
     payable of Seller for the purchase by Seller, the shipment to Seller or the
     handling prior to delivery to Seller of any Inventory to the extent Seller
     is paid for such Inventory pursuant to Section 3.3 and such accounts
     payable are not deducted in determining the Purchase Price for such
     Inventory. If, prior to Closing, Seller is paid any license fees, tariffs,
     rentals, service fees, payments for utilities, or other similar revenues
     with respect to the Assets or Seller's Business which under GAAP are
     attributable, in whole or in part, to the period after the Closing Date,
     Refinery Buyer shall be entitled to a credit in the Adjustment Amount with
     respect to the portion thereof which under GAAP is attributable to the
     period after the Closing Date.

          (ii) Refinery Buyer acknowledges that, from time to time, Seller
     enters into agreements for the future delivery of crude oil necessary for
     the continued operation of the Facility, and that Seller may deem it
     necessary to enter into such agreements following the date hereof and
     through the Closing Date. Refinery Buyer further acknowledges that some of
     those agreements require Seller to prepay for such future deliveries of
     crude oil and others require that Seller provide the crude oil supplier
     with letters of credit issued on behalf of Seller to secure Seller's
     obligation to pay for such future deliveries of crude oil ("Crude Supply
     LCs"). Prior to Closing, Seller and Buyers shall (a) amend SCHEDULE A-3 to
     include any such crude oil supply agreements entered into by Seller as
     contemplated in this paragraph (ii) of Section 3.4 and (b) amend SCHEDULE
     9.7 to include any such Crude Supply LCs issued on behalf of Seller as
     contemplated in this paragraph (ii) of Section 3.4. At Closing, Seller
     shall be entitled to a credit in the Adjustment Statement for such
     prepayments for crude oil to the extent such crude oil is not delivered at
     the Facility prior to Closing. At Closing, Refinery Buyer shall cause to be
     delivered to each applicable beneficiary of such Crude Supply LCs a
     replacement letter of credit or other obligation deemed satisfactory by
     such beneficiary and shall cause the release as of the Closing Date of
     Seller and its Affiliates from all obligations and liabilities relating to
     such Crude Supply LCs, in the manner provided in Section 9.7 with respect
     to Existing Credit Support, provided that, Refinery Buyer shall be entitled
     to a credit in the Adjustment Statement for the unpaid cost of any such
     crude oil which has been received at the Facility prior to the Closing and
     for which Refinery Buyer causes to be delivered to the applicable
     beneficiary a replacement letter of credit pursuant to this paragraph (ii)
     of Section 3.4. Not less than two days prior to the Closing Date, Seller
     will provide Refinery Buyer with an estimate of the aggregate amounts of
     (a) prepayments for crude oil, (b) Crude Supply LCs and (c) crude oil
     received under Crude Supply LCs, as contemplated in this paragraph (ii) of
     Section 3.4, which amounts will be calculated by Seller from Sellers' books
     and records and reflected in the Adjustment Statement, subject to
     post-Closing review and adjustment in accordance with the provisions of
     Section 3.5.

          Section 3.5 Post Closing Review of Adjustment Amount. After the
Closing, Seller shall review the Adjustment Statement and determine the actual
Adjustment Amount. On or prior to the 20th day after the Closing Date, Seller
shall present Refinery Buyer with a statement of the actual Adjustment Amount
and such supporting documentation as is reasonably necessary to support the
Adjustment Amount shown therein (the "Final Adjustment Statement"). Refinery
Buyer will give personnel, accountants and representatives of Seller reasonable
access to the Assets and Refinery Buyer's premises and to its books and records
for purposes of preparing the Final Adjustment Statement and will cause
appropriate personnel of Refinery Buyer to assist Seller and Seller's personnel,
accountants and representatives, at no cost to Seller, in the preparation of the
Final Adjustment Statement. Seller will give personnel, accountants and
representatives of Refinery Buyer reasonable access to Seller's premises and to
its books and records for purposes of reviewing the calculation of Adjustment
Amount and will cause appropriate personnel of Seller to assist Refinery Buyer
and Refinery Buyer's personnel, accountants and representatives, at no cost to
Refinery Buyer, in verification of such calculation. The Final Adjustment
Statement shall become final and binding on Seller and Refinery Buyer as

                                       -7-

<PAGE>

to the Adjustment Amount 20 days following the date the Final Adjustment
Statement is received by Refinery Buyer, except to the extent that prior to the
expiration of such 20-day period Refinery Buyer shall deliver to Seller one or
more notices, as hereinafter required, of its disagreement with the contents of
the Final Adjustment Statement. Such notices shall be in writing and set forth
all of Refinery Buyer's disagreements with respect to any portion of the Final
Adjustment Statement, together with Refinery Buyer's proposed changes thereto,
and shall include an explanation in reasonable detail of, and such supporting
documentation as is reasonably necessary to support, such changes. Any
disagreements with or changes to the Final Adjustment Statement not included in
such notices shall be waived by Refinery Buyer. If Refinery Buyer has timely
delivered one or more notices of disagreement to Seller in the manner required
above, then, upon written agreement between Refinery Buyer and Seller resolving
all disagreements of Refinery Buyer set forth in such notices, the Final
Adjustment Statement (including any revisions thereto as are so agreed) will
become final and binding on Refinery Buyer and Seller as to the Adjustment
Amount. If the Final Adjustment Statement has not become final and binding by
the 45th day following the date the Final Adjustment Statement is received by
Refinery Buyer, then any unresolved disagreements of Refinery Buyer set forth in
the aforesaid notices will be submitted to the Independent Arbitrator for
determination. Seller and Refinery Buyer may submit to the Independent
Arbitrator any facts which they deem relevant to the determination. The written
report of the Independent Arbitrator shall be delivered to Seller and Refinery
Buyer within thirty (30) days after such disputed items and amounts are
submitted to the Independent Arbitrator for determination. Upon resolution of
such unresolved disagreements of Refinery Buyer by the Independent Arbitrator,
the Final Adjustment Statement (including any revisions thereto as are so
resolved or agreed), shall be conclusive, final and binding on Refinery Buyer
and Seller as to the Adjustment Amount and shall not be subject to challenge
before any court of law or arbitration tribunal. Judgment may be entered upon
the determination of the Independent Arbitrator in any court having jurisdiction
over the Party against which such determination is to be enforced. The fees and
expenses of the Independent Arbitrator shall be borne by Seller and Refinery
Buyer in inverse proportion as they may prevail on matters resolved by the
Independent Arbitrator, which proportionate allocations shall also be determined
by the Independent Arbitrator at the time the determination of the Independent
Arbitrator is rendered on the merits of the matters submitted. Any fees and
expenses of Seller's and Refinery Buyer's own independent public accountants
incurred in connection with their determination or review of the Adjustment
Amount or the Final Adjustment Statement shall be borne by the Party retaining
such independent public accountants. If the final amount of the Adjustment
Amount is more or less than the Initial Adjustment Amount, the Closing Payment
shall be redetermined under Section 3.2(b) using such final amount of the
Adjustment Amount. If such redetermination under Section 3.2(b) results in a
reduction in the Closing Payment, Seller shall pay Refinery Buyer the amount of
such reduction. If such redetermination results in an increase in the Closing
Payment, Refinery Buyer shall pay Seller the amount of such increase. Within
three (3) Business Days after the Final Adjustment Statement (as so resolved or
agreed) becomes final and binding, Seller or Refinery Buyer, as appropriate,
shall pay to the other Party the amount of such increase or reduction, if any,
in the Closing Payment and, if not paid by 12:00 noon Central Time on the last
day of said 3-Business Day period, together with interest thereon at a rate
equal to the Agreed Rate from and including the last day of said 3-Business Day

                                       -8-

<PAGE>

period to but excluding the date of payment if paid by 12:00 noon Central Time.
Notwithstanding the foregoing, if the actual amount(s) of any Property Taxes for
the Current Tax Period are not known prior to the date on which the Final
Adjustment Statement is prepared, then adjustments to the Closing Payment with
respect to such Property Taxes for the Current Tax Period shall be made pursuant
to Section 12.1 and not this Section.

          Section 3.6 Purchase Price Allocations. The Purchase Price shall be
allocated among the (i) Sites, (ii) the Facility, (iii) the various items of
equipment and personal property included in the Assets, (iv) the other Assets
and (v) the Land Newco Shares and Pipeline Newco Shares in the manner and in
accordance with the respective values set forth in SCHEDULE 3.6. Within ten (10)
days after the execution and delivery of this Agreement by Buyers and Seller,
Buyers shall in good faith prepare and deliver to Seller a proposed SCHEDULE 3.6
setting forth the foregoing allocations of the Purchase Price. The allocations
of the Purchase Price in SCHEDULE 3.6 shall be in sufficient detail to permit
the determination and calculation of all sales, use and similar Taxes, if any,
which may be due on portions of the Assets in connection with this transaction.
The allocations of the Purchase Price in the SCHEDULE 3.6 prepared and delivered
by Buyers shall be subject to Seller's approval, which approval will not be
unreasonably withheld, conditioned or delayed. Upon the approval by Seller and
Buyers of SCHEDULE 3.6 pursuant to the foregoing, said approved SCHEDULE 3.6
shall be attached to and incorporated in this Agreement for all purposes. If any
adjustment is made to the Purchase Price pursuant to Section 3.3 or 3.5, a
corresponding adjustment shall be made to the portion(s) of the Purchase Price
allocated to the affected Asset(s) in the SCHEDULE 3.6. The Parties shall not
take a federal or state Tax reporting position inconsistent with the allocations
set forth on SCHEDULE 3.6.

                                    ARTICLE 4

transactions contemplated hereby have been duly and validly authorized by all
requisite corporate action on the part of Seller.

          (d) Enforceability. This Agreement constitutes a valid and binding

     the Company's Assets;

     upon the consummation of the transactions contemplated hereunder, except
     where the failure by Seller to have such right would not, individually or

     any Contract, license, sublicense, assignment, or indemnification which
     relates to any of the Intellectual Property, except for such breaches as to

Newco shall incur any liability.

          (n) Environmental Matters. The sole representations and warranties of

4.1(n). To the extent representations and warranties in other sections of this

by all requisite partnership and/or corporate action on the part of Buyers.

          (c) Enforceability. This Agreement constitutes a valid and binding
agreement of Buyers enforceable against Buyers in accordance with its terms,
except as may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws from time to time in effect that affect creditors'
rights generally and by legal and equitable limitations on the availability of
specific remedies.

          (d) No Conflict or Violation. Except for any exceptions set forth in
Section 4.2(e) (or referenced in SCHEDULE 4.2(E)), the execution and delivery of
this Agreement by Buyers and the consummation of the transactions and
performance of the terms and conditions contemplated hereby by Buyers will not,
with or without the passage of time or the giving of notice or both,

          (i) conflict with or result in a violation or breach of or default
     under any provision of the certificate of limited partnership, limited
     partnership agreement, certificate of incorporation, by-laws or other
     similar governing documents of any Buyer,

          (ii) conflict with, constitute a breach, violation or termination of
     any provision of, or give rise to any right of termination, cancellation or
     acceleration, or loss of any material right or benefit or both, under any
     Contract or other undertaking to which any Buyer is a party or by which any
     Buyer or its material properties may be bound, or

          (iii) violate any Law applicable to any Buyer or any of its material
     properties;

except, with respect to clauses (ii) and (iii), for such violations, conflicts,
breaches, terminations, losses and other matters which will not, individually or
in the aggregate, result in a Material Adverse Effect, prevent or materially
delay the consummation of the transactions contemplated by this Agreement or
prevent any Buyer from performing its obligations under this Agreement.

          (e) Consents. Except for (i) Post-Closing Consents, (ii) the transfer
or obtaining of any Environmental Permit, (iii) compliance with and filings
under the HSR Act, (iv) consents, approvals, authorizations, permits, filings or
notices, the failure of which to obtain or with which to comply will not,
individually or in the aggregate, have a Material Adverse Effect, and (v)
consents, approvals, authorizations, permits, filings or notices referenced in
SCHEDULE 4.2(E), no consent, approval, authorization or permit of, or filing
with or notification to, any Person is required for or in connection with the
execution and delivery of this Agreement by any Buyer or for or in connection
with the consummation of the transactions and performance of the terms and
conditions contemplated hereby by any Buyer.

          (f) Actions. Except (i) as set forth in SCHEDULE 4.2(F) and (ii) for
any Action initiated by Seller or any Affiliate of Seller, (A) there is no
Action pending or, to the knowledge of any Buyer, threatened to which any Buyer
is (or is threatened to be made) a party and which would, individually or in the
aggregate, have a Material Adverse Effect or seeks to prevent the consummation
by any Buyer of the transactions contemplated by this Agreement, and (B) there
is no outstanding order, writ, injunction, decree or judgment entered in any
Action in which any Buyer or an Affiliate of any Buyer has been joined as a
party that is binding upon any Buyer or an Affiliate of any Buyer and which
would, individually or in the aggregate, have a Material Adverse Effect or would
prevent the consummation by any Buyer of the transactions contemplated by this
Agreement.

          (g) Brokerage Fees and Commissions. Lehman Brothers is acting as
investment banker for Buyers in connection with the purchase of the Assets and
the Newco

                                      -23-

<PAGE>

Shares. However, no Buyer nor any Affiliate of any Buyer has incurred any
obligation or entered into any Contract for any investment banking, brokerage or
finder's fee or commission in respect of the transactions contemplated by this
Agreement for which Seller shall incur any liability.

          (h) Funds. At Closing Buyers will have sufficient funds available to
enable Buyers to consummate the transactions contemplated hereby and to pay the
Closing Payment and all related fees and expenses of Buyers.

          (i) No Distribution. Buyers have made their own independent judgment
of the commercial potential, condition and usefulness of the Assets and the
Newco Shares, taking into consideration all current Laws, including
Environmental Laws, and assuming all risks associated with the likelihood that
such Laws will change in the future. Buyers have such experience and knowledge
in business and financial affairs in general, and of the oil refining business
as conducted and regulated in Texas in particular, as to be capable of
evaluating all of the merits and risks of this transaction. Buyers are able to
bear the economic risks of their acquisition and ownership of the Assets and the
Newco Shares. Prior to entering into this Agreement, Buyers were advised by
their counsel and such other persons they have deemed appropriate concerning
this Agreement and the Assets and the Newco Shares. Each of Refinery Buyer and
Pipeline Buyer is an "accredited investor," as such term is defined in
Regulation D of the Securities Act of 1933, as amended, and will acquire the
Assets and the Pipeline Newco Shares, as the case may be, for its own account
and not with a view to a sale or distribution thereof in violation of the
Securities Act of 1933, as amended, and the rules and regulations thereunder,
any applicable state blue sky laws or any other applicable securities laws.

          (j) Bankruptcy. There are no bankruptcy, reorganization or arrangement
proceedings pending against, being contemplated by, or to the knowledge of any
Buyer, threatened against any Buyer or any Affiliate of any Buyer.

          (k) EPA Waiver Application. Contemporaneously with the execution of
this Agreement, Refinery Buyer has submitted to the EPA an Application for a
Hardship Waiver containing all information required under 40 C.F.R. Section
80.270, requesting approval to comply with the gasoline sulfur standards
referenced in such Application for a period of 36 months, in respect of Refinery
Buyer's contemplated acquisition and operation of the Facility. Except for the
period (e.g. 36 months) for which such waiver has been applied for, Refinery
Buyer's Application seeks approval for operation of the Facility on the same
basis as approved by the EPA for Seller's currently effective Hardship Waiver
for the Facility, a copy of which waiver in favor of Seller is set forth in
SCHEDULE 4.2(K).

                             ACCESS TO INFORMATION

          Section 5.1 General Access. Subject to Section 5.2, Section 5.3,
Section 5.4 and Section 6.1 (which shall govern all environmental reviews,
inspections and audits), promptly

                                      -24-

<PAGE>

following the execution of this Agreement and until the first to occur of (i)
the Closing Date and (ii) the termination of this Agreement, Seller shall:

          (a) permit Buyers and their Representatives to have reasonable access
during normal business hours in the Seller's and the Company's offices, and in a
manner so as not to interfere unduly with the business operations of Seller or
the Company, to Seller's and the Company's books, records, contracts, abstracts
of title, title opinions, title files, ownership maps, lease files, assignments,
and documents relating to the Assets and the Company Shares and Company's Assets
insofar as the same are in Seller's or the Company's possession and insofar as
Seller has been able to do so without (i) violating legal constraints or any
legal obligation or (ii) waiving any attorney/client, work product or like
privilege; and

          (b) subject to any required consent of any third Person, permit Buyers
and their Representatives during normal business hours and at Buyers' sole risk,
cost and expense, to conduct, in the presence of Seller's Representatives,
reasonable inspections of the Assets and the Company's Assets in a manner so as
not to interfere unduly with the business operations of Seller or the Company;

provided, however, Buyers shall repair any damage to the Assets or the Company's
Assets resulting from such inspections and Buyers do hereby, jointly and
severally, indemnify and hold harmless, release and agree to defend the Seller
Indemnitees from and against any and all Covered Liabilities arising, in whole
or in part, from Buyers' foregoing access or inspection of the Assets or the
Company's Assets, REGARDLESS OF ANY NEGLIGENCE OR STRICT LIABILITY ON THE PART
OF SELLER OR ANY OTHER SELLER INDEMNITEE AND REGARDLESS OF THE FORM OF CLAIM
WHETHER AT COMMON LAW, STRICT LIABILITY, NEGLIGENCE OR UNDER ANY STATUTE OR
REGULATION.

          Section 5.2 Limitations on Access. Nothing in this Agreement shall be
construed to permit Buyers or their Representatives to have access to any files,
records, contracts or documents of Seller or any Affiliate of Seller relating to
(i) Seller's or any of its Affiliate's feedstock and product pricing information
for transactions between Seller and any of its Affiliates or internally within
Seller or any of its Affiliates, internal transfer prices, hedging activity
records and hydrocarbon inventory valuation procedures and records, or (ii) this
transaction, including any bids or offers heretofore or hereafter received by
Seller for the sale of the Assets and/or the Newco Shares in competition with
the Buyers' bid or offer, it being agreed that all such competing bids or offers
shall be the sole property of Seller.

          Section 5.3 Confidential Information.

          (a) General Restrictions. Buyers shall maintain all information made
available to them pursuant to or in connection with this Agreement confidential
and shall cause their directors, officers, employees, Affiliates,
Representatives and advisors to maintain all information made available to them
pursuant to or in connection with this Agreement confidential, all as provided
in the Confidentiality Agreement, which shall continue in full force and effect
and the terms of which are incorporated herein by reference and made a part of
this Agreement. Subject to Section 5.3(b), following the Closing, the foregoing
information with

                                      -25-

<PAGE>

respect to the Assets or Seller's Business and the Company's Assets or the
Company's Business and the Confidential Information with respect to the Assets
or Seller's Business and the Company's Assets or the Company's Business that is
or has been made available pursuant to or in connection with this Agreement or
the Confidentiality Agreement shall cease to be subject to the Confidentiality
Agreement.

          (b) Special Confidential Information. Notwithstanding anything to the
contrary in this Agreement, any Confidential Information that relates to any
settlement or agreement with any third party relating to Environmental
Liabilities shall remain subject to the Confidentiality Agreement in accordance
with the terms of the Confidentiality Agreement.

          Section 5.4 No Exclusivity. The rights of Buyers under this Article 5
are not exclusive, and Seller shall have the right at any time or times prior to
Closing to permit third Persons selected by Seller access to Seller's and the
Company's books, records, and other documents and materials mentioned in Section
5.1(a), and to permit such third Persons to conduct inspections of the Assets
and the Company's Assets; provided, however, (a) the foregoing provisions of
this Section 5.4 shall not be construed to permit Seller to enter into any
agreement with any such third Persons the performance of which would prevent
Seller from consummating the transactions with Buyers contemplated hereby in
accordance with the terms and conditions hereof, and (b) Seller shall not
furnish any such third Persons copies of this Agreement or any Related Agreement
or otherwise disclose to any such third Persons the terms hereof or thereof.

                                    ARTICLE 6
                              ENVIRONMENTAL MATTERS

          Section 6.1 Environmental Review and Audit.

          (a) Environmental Access. Promptly following the execution of this
Agreement and until the first to occur of (i) the Closing Date, (ii) the
expiration of the 30-day period commencing on the execution of this Agreement
and (iii) the termination of this Agreement (the "Environmental Examination
Period"), subject to the restrictions contained in this Agreement and any
required consent or waiver of any third Person, Seller shall permit Buyers
(acting through their authorized employees and the Environmental Consultant) to
have reasonable access during normal business hours (i) in the Seller's and the
Company's offices, and in a manner so as not to interfere unduly with the
business operations of Seller or the Company, to Seller's and the Company's
environmental files and records in Seller's or the Company's possession relating
to the Assets and the Company's Assets insofar as Seller may do so without (1)
violating legal constraints or any legal obligation or (2) waiving any
attorney/client, work product or other privilege, and (ii) to the Assets and the
Company's Assets for the purpose of allowing Buyers and their Environmental
Consultant to conduct a Phase I Environmental Assessment and a limited
compliance review with respect to the Assets and the Company's Assets, but
expressly excluding any right to collect samples (including soil and groundwater
samples), drill holes or to conduct or perform any other tests or a Phase II
environmental audit with respect to the Assets or the Company's Assets without
the express

                                      -26-

<PAGE>

written consent of Seller, which consent shall not be unreasonably withheld,
conditioned or delayed (collectively, "Buyers' Environmental Review"), all at
Buyers' sole risk, cost and expense.

          (b) Conduct of Review. Prior to conducting Buyers' Environmental
Review, Buyers shall furnish Seller with a proposed scope of Buyers'
Environmental Review, including a description of the activities to be conducted
and the locations of such activities. No third Person, other than the
Environmental Consultant and Buyers' authorized employees, may conduct Buyers'
Environmental Review. Buyers shall not commence any activity proposed to be
included in Buyers' Environmental Review unless and until such activity
(including the location thereof) has been approved in writing by Seller which
approval shall not be unreasonably withheld, conditioned or delayed. Seller
shall have the right to be present during any inspection or testing (including
sampling) undertaken pursuant to Buyers' Environmental Review and shall have the
right, at its option and expense, to split samples with Buyers. Buyers shall
give Seller notice not more than seven (7) days and not less than 48 hours
before any visits by Buyers or the Environmental Consultant to the Assets or the
Company's Assets; provided, however, to the extent that a visit is scheduled
under the terms of a written proposal for Phase II environmental audit
activities submitted by Buyers and approved by Seller in writing, no additional
notice of such visit shall be required hereunder.

          (c) Buyers' Responsibility for Review. In connection with Buyers'
Environmental Review, Buyers agree that Buyers, the Environmental Consultant and
Buyers' employees, agents and contractors shall comply with all Laws and any
reasonable restrictions imposed by Seller, including restrictions related to
worker safety, and shall exercise due care with respect to the Assets and the
Company's Assets and their condition, taking into consideration the
characteristics of any wastes or substances found thereon, and in light of all
relevant facts and circumstances. Specifically, but without limitation, when
handling solid waste or hazardous substances, if any, discovered during the
inspection of the Assets and the Company's Assets, Buyers, the Environmental
Consultant and Buyers' employees, agents and contractors shall handle such waste
or substances in accordance with all Laws. Any soil or water samples taken by
Buyers from the Assets or the Company's Assets shall become the sole property
and possession of Buyers and will be managed and disposed of consistent with the
applicable rules and regulations of the EPA and other applicable Governmental
Authority with regulatory authority. Promptly after completing any sampling
approved in writing by Seller, Buyers shall, at their sole cost and expense,
remove and dispose of in compliance with all Laws all drill cuttings, soil,
debris or liquids generated from or in connection with Buyers' Environmental
Review and restore the Assets and the Company's Assets to their original
condition, in accordance with good engineering practice and all Laws, if changed
due to Buyers' Environmental Review. Failure by Buyers to comply with the
requirements of this subsection within a reasonable time period will entitle
(but shall not obligate) Seller to take any action deemed necessary or
appropriate by Seller to correct such failure, all at Buyers' expense. Buyers
shall maintain and shall cause their Representatives, contractors, consultants
and advisors to maintain all information obtained pursuant to Buyers'
Environmental Review strictly confidential and shall not disclose the same to
any third Person without the prior written consent of Seller, except to the
extent required by Law. Buyers shall provide Seller's counsel with

                                      -27-

<PAGE>

copies of any reports prepared and analytical test results received by Buyers or
the Environmental Consultant promptly following Buyers' or the Environmental
Consultant's preparation or receipt of the same. Buyers, jointly and severally,
do hereby indemnify and hold harmless, release and agree to defend the Seller
Indemnitees from and against any and all Covered Liabilities, including all
Environmental Liabilities, arising out of any violation by Buyers, the
Environmental Consultant, or Buyers' or the Environmental Consultant's
Representatives, contractors, consultants and advisors of the provisions of this
Section 6.1 or, in whole or in part, from Buyers' or the Environmental
Consultant's inspection or testing of the Assets and the Company's Assets or
handling any substances or samples in connection therewith, REGARDLESS OF ANY
NEGLIGENCE OR STRICT LIABILITY ON THE PART OF SELLER OR ANY OTHER SELLER
INDEMNITEE AND REGARDLESS OF THE FORM OF CLAIM WHETHER AT COMMON LAW, STRICT
LIABILITY, NEGLIGENCE OR UNDER ANY STATUTE OR REGULATION. For the avoidance of
doubt, Buyers' obligation for indemnification under this Section 6.1 shall not
be construed to impose liability on Buyers solely as a result of the discovery
of Environmental Conditions in the course of Buyers' inspection of the Assets
pursuant to this Section 6.1.

                                    ARTICLE 7
                                 TITLE MATTERS

          Section 7.1 Title Commitment and Survey. Prior to the execution of
this Agreement, Seller has provided Refinery Buyer with (i) a recent survey of
each Site (the "Surveys"), (ii) a recent title policy commitment issued by
Stewart Title Company (the "Title Company") covering each Site (the "Title
Commitment") and (iii) copies of all documents referenced as exceptions to title
in each of the Title Commitments. Seller shall not be obligated to furnish any
policy of title insurance issued by the Title Company or otherwise in respect of
any Site (a "Title Policy"), and it shall not be a requirement of or condition
to the Closing that any Buyer obtain or be able to obtain any Title Policy or
that any Buyer have or be able to have the survey exception in any Title Policy
modified in any manner or that any other special endorsements be made to any
Title Policy, including any endorsement regarding restrictive covenants. All
costs of any Title Policies shall be borne solely by Refinery Buyer.
Notwithstanding the foregoing, if requested by Refinery Buyer prior to Closing,
Seller shall use reasonable best efforts to cause the Title Company to provide
to Refinery Buyer at Closing, upon Refinery Buyer's payment of the premium
therefor, a pro forma Title Policy consistent with the Title Commitment and
reflecting the form in which the Title Policy shall be issued to Refinery Buyer
incident to Closing.

          Section 7.2 Limited Title Warranty. Except for the representations and
warranties set forth in Section 4.1(p), Seller makes no warranty or
representation, express, implied, statutory or otherwise, with respect or in any
manner relating to Seller's title to any of the Assets or the Company's title to
any of the Company's Assets. Seller's warranties and representations under
Section 4.1(p) shall cease and terminate and be of no further force and effect
upon the expiration of the applicable survival periods therefor set forth in
Section 12.3. For the avoidance of doubt, the immediately preceding sentence
hereof shall not be construed to limit Seller's special warranty of title to be
contained in the Deed to be delivered to Refinery Buyer at Closing.

                                      -28-

<PAGE>

          Section 7.3 No Other Breach. Notwithstanding anything provided to the
contrary in Section 4.1 or Article 15, Buyers' sole recourse and remedy with
respect to or on account of any encumbrance against title, or loss or lack of
title, or defect in title to any Asset or any of the Company's Assets shall be
pursuant to Seller's limited representations and warranties set forth in Section
4.1(p) for the respective survival periods therefor, if any, and Buyers shall be
precluded from also asserting such matter as the basis of the breach of any
other representation or warranty under Section 4.1 or for recovery on any
indemnity under Article 15 (except with respect to Section 4.1(p) for the
respective survival periods therefor, if any).

                                    ARTICLE 8
                             TRANSFER REQUIREMENTS

          Section 8.1 Compliance. Refinery Buyer's purchase of the Assets is
expressly subject to all validly existing and applicable Transfer Requirements.
To Seller's knowledge, all agreements containing a Transfer Requirement (other
than Restrictions with respect to Restricted Properties, Transfer Requirements
with respect to Environmental Permits, and Post-Closing Consents) burdening any
material Asset are set forth in SCHEDULE 8.1. As promptly as practicable after
the date of execution of this Agreement but in any event prior to the Closing
Date, Seller shall initiate all procedures which in Seller's good faith judgment
are reasonably required to comply with all Transfer Requirements set forth in
SCHEDULE 8.1 with respect to the transactions contemplated by this Agreement.
Seller shall not be obligated to pay any consideration to (or incur any cost or
expense for the benefit of) the holder of any Transfer Requirement in order to
comply therewith. Restrictions with respect to Restricted Properties and
Transfer Requirements with respect to Environmental Permits are governed by
Section 9.3(b) and 9.3(c), respectively, and are not governed by this Article 8.

          Section 8.2 Transfer Requirements. If a Transfer Requirement governed
by this Article 8 (other than a Post-Closing Consent) which is required to be
obtained, complied with or otherwise satisfied before title to an Asset or
portion thereof can be transferred to Refinery Buyer as contemplated by this
Agreement is not obtained, complied with or otherwise satisfied prior to the
Closing Date, then, unless such Transfer Requirement affects a material Asset or
portion thereof or unless otherwise mutually agreed by Seller and Refinery
Buyer, any Asset or portion thereof affected by such Transfer Requirement (a
"Retained Asset") shall be held back from the Assets to be transferred and
conveyed to Refinery Buyer at Closing and the Purchase Price to be paid at
Closing shall be reduced by the portion of the Purchase Price which Refinery
Buyer and Seller mutually agree to allocate to such Retained Asset. Any Retained
Asset so held back at the initial Closing will be conveyed to Refinery Buyer at
a delayed closing (which shall become the new Closing Date with respect to such
Retained Asset), within ten (10) days following the date on which Seller
obtains, complies with or otherwise satisfies all such Transfer Requirements
with respect to such Retained Asset as contemplated above in this Section, for a
purchase price equal to the amount by which the Purchase Price was reduced on
account of the holding back of such Retained Asset; provided, however, if all
such Transfer Requirements with respect to any Retained Asset so held back at
the initial Closing are not obtained, complied with or otherwise satisfied as
contemplated by above in this Section within 365 days after the initial Closing
has occurred with respect to any Assets, then such Retained

                                      -29-

<PAGE>

Asset shall be eliminated from the Assets and this Agreement, unless Seller and
Refinery Buyer mutually agree to proceed with a closing on such Retained Asset
in which case Refinery Buyer shall be deemed to have waived any objection with
respect to non-compliance with such Transfer Requirements. If Refinery Buyer and
Seller are unable to mutually agree on the portion of the Purchase Price to be
allocated to a Retained Asset, (i) the allocation of the Purchase Price to such
Retained Asset shall be determined by arbitration pursuant to Section 16.12,
(ii) the Closing shall not be delayed as a result of such dispute, (iii) on the
Closing Date for the original Closing under this Agreement, Seller, Refinery
Buyer and the Escrow Agent shall execute and deliver an amendment to the Earnest
Money Deposit Escrow Agreement, in substantially the form of EXHIBIT 8.2, and
Refinery Buyer shall pay to the Escrow Agent to be held in escrow in accordance
with the Earnest Money Deposit Escrow Agreement (as so amended) an amount equal
to the larger of the portions of the Purchase Price which either Party proposes
to allocate to such Retained Asset, (iv) if the portion of the Purchase Price
determined, by arbitration or the subsequent mutual agreement of the Parties, to
be allocable to such Retained Asset is less than the amount required to be paid
into escrow with respect to such dispute, an amount equal to the difference,
together with all interest and other amounts earned thereon, shall be paid by
the Escrow Agent to Seller, and (v) the remaining amount paid into escrow in
connection with such dispute, together with all interest and other amounts
earned thereon, shall be paid by the Escrow Agent to (a) Seller if the Closing
subsequently occurs with respect to such Retained Asset or (b) Refinery Buyer if
such Retained Asset is subsequently eliminated from the Assets pursuant to this
Section. Seller and Refinery Buyer each agree to execute and deliver to the
Escrow Agent written instructions to the Escrow Agent directing the Escrow Agent
to deliver the amount paid into escrow, together with all interest and other
amounts, if any, earned thereon, to Seller or Refinery Buyer, as the case may
be, in accordance with the provisions of this Section 8.2 and the terms of the
Earnest Money Deposit Escrow Agreement as so amended.

          Section 8.3 Post-Closing Consents. Refinery Buyer will use its
commercially reasonable best efforts after Closing to obtain all approvals,
consents and permits, give all notices, and make all filings required to comply
with the Post-Closing Consents in connection with the assignment and transfer of
the Assets from Seller to Refinery Buyer.

                                    ARTICLE 9
                         COVENANTS OF SELLER AND BUYERS

          Section 9.1 Conduct of Business Pending Closing. Except as disclosed
in SCHEDULE 9.1 or as otherwise contemplated herein or consented to or approved
by Buyers (which consent or approval shall not be unreasonably withheld,
conditioned or delayed), from the date hereof through the Closing Date, Seller
(subject to and except for the constraints of and actions required by the
existing agreements of Seller relating to the Assets) covenants and agrees that

System,

          (d) not transfer, sell or dispose of any tangible property, or remove
any books and records at the site of the Assets used or useful in the business

with past practice, (ii) personal property or equipment which is replaced with
personal property or equipment of comparable or better value and utility in
connection with the maintenance, repair and operation of the Assets, (iii) any
item of personal property or equipment having a value of less than $20,000.00,
and (iv) Excluded Assets; and cause the Company not to transfer, sell or dispose
of any tangible property, or remove any books and records at the site of the
Company's Assets used or useful in the business being conducted at such sites,
except for (i) personal property or equipment which is replaced with personal

          (e) not place, and cause the Company not to place, any Lien on the
Assets or the McMurrey Pipeline System except (i) in connection with the
performance by Seller or the Company of an obligation or agreement existing on
the date hereof, and which has been disclosed in writing to Buyers, or pursuant
to this Agreement and (ii) Permitted Encumbrances,

          (f) not grant any general wage or benefit increase to the Personnel
except consistent with past practice or as provided for in the PACE Local 4-202
Labor Agreements,

          (g) notify Buyers promptly, and in any event prior to the Closing, of
any written notice of a material violation or written threatened notice of a
material violation received from any Governmental Authority after the date of
this Agreement relating to Environmental Laws or Environmental Permits at the
Facility or the Sites or with respect to the McMurrey Pipeline System,

          (h) not allow the Company to declare or pay any dividends, or make any
distributions, in respect of, or issue any of, its equity securities or
securities convertible into its equity securities, or repurchase, redeem or
otherwise acquire any such securities or make or propose to make any other
change in its capitalization other than pursuant to Section 9.11;

          (i) not allow the Company to merge into or with or consolidate with
any other Person or acquire all or substantially all of the business or assets
of any Person;

                                      -31-

<PAGE>

          (j) not allow the Company to make any change in its articles of
incorporation or by-laws;

          (k) not allow the Company to take any action or to enter into any
commitment with respect to or in contemplation of any liquidation, dissolution,
recapitalization, reorganization or other winding up of its business or

          (l) not allow the Company to change its accounting policies or
practices (including any change in depreciation or amortization policies),
except as required under GAAP;

          (m) not allow the Company to enter into any employment agreement not
terminable at will;

          (n) not amend any Material Contract in any material respect and not
enter or allow the Company to enter into any Contract which, if it existed on
the date of execution of this Agreement, would constitute a Material Contract,
if such Contract would become binding upon Buyer at Closing or would materially
and adversely affect the operation of the Assets or the Company's Assets after
Closing;

          (o) not allow the Company to pay or provide for any loan or payment or
advance of any nature whatsoever to Seller or any Affiliate of Seller;

          (p) not allow the Company to enter into, amend or terminate any
collective bargaining or labor agreement;

          (q) not allow the Company to make any single capital expenditure or
commitment in excess of $50,000.00 for additions to property, plant, equipment
or intangible capital asset or for any other purpose, or make such capital
expenditures or commitments exceeding in the aggregate $100,000.00;

          (r) not agree to the settlement or resolution of any Action involving
the Company unless in the ordinary course of business consistent with past
practices, not involving Affiliates and not exceeding $50,000.00 individually or
$100,000.00 in the aggregate;

          (s) not allow the Company to create or change any employee benefit
plans (within the meaning of section 3(3) of ERISA) or any other employee
benefit plan or program not subject to ERISA, established, contributed to, or
maintained by the Company with respect to the Personnel, except as required by
Law.

Notwithstanding the foregoing, Seller may take (or not take, as the case may be)
any actions contrary to the foregoing to the extent reasonably necessary under
emergency circumstances (or if required or prohibited, as the case may be,
pursuant to Law) and provided Buyers are notified as soon thereafter as
practicable.

          Section 9.3 Actions and Efforts by Parties.

          (a) Parties Efforts and Further Assurances.

          (i) Buyers shall take all actions which are necessary for them to be
     in compliance with their warranties and representations contained in
     Sections 4.2(h) and 4.2(i) on the Closing Date. Each of the Parties shall
     use its commercially reasonable best efforts (and to cause its Affiliates
     to use their commercially reasonable best efforts) to refrain from taking
     any action within its control which would cause a breach of any of its
     representations and warranties contained in Article 4 or which would
     prevent it from delivering to the other Party the certificate which it is
     required to deliver pursuant to Section 10.1(b) or 10.2(b), as the case may
     be. Seller agrees to give Buyers prompt notice of the satisfaction of the
     conditions set forth in Section 10.l(h). Buyers agree to give Seller
     prompt notice of the satisfaction of the conditions set forth in Section
     10.2(h).

          (ii) From time to time after the Closing Date, Seller and Buyers will
     each execute and deliver or cause their respective Affiliates to execute
     and deliver such further instruments, and take (or cause their respective
     Affiliates to take) such other action, as may be necessary to carry out the
     purposes and intents of this Agreement.

          (iii) Upon request by a Party from time to time after the Closing Date
     and until the fifth anniversary of the Closing, the other Party shall, at
     no expense to such Party, cooperate to the extent reasonably possible in
     making its employees available for meetings or discussions with the
     requesting Party with respect to matters in dispute between the requesting
     Party and Third Parties concerning the Assets or any part thereof or the
     Company's Assets or any part thereof; provided such access shall be during
     normal business hours, with notice of not less than five (5) Business Days,
     and shall not interfere unduly with the normal business activities of such
     employees.

          (iv) Seller shall undertake to keep Refinery Buyer reasonably informed
     from time to time regarding developments concerning the enforcement action
     being contemplated by the EPA and the DOJ for potential violations of air
     regulations at the Facility (the "EPA/DOJ Action") and shall afford
     Refinery Buyer and its authorized representatives a reasonable opportunity
     to participate in discussions and to attend meetings between Seller, on the
     one hand, and the U.S. Department of Justice and any other Governmental
     Authority, on the other hand, relating to the EPA/DOJ Action; provided,
     however, Seller shall at all times control the defense and any settlement
     of the EPA/DOJ Action and neither Seller nor its Affiliates shall be
     required to obtain the consent or approval of Refinery Buyer or any of its
     Affiliates in connection with any Order approved or entered into by Seller
     or any of its Affiliates arising out of or in connection with the EPA/DOJ
     Action. For the avoidance of doubt, all Environmental Fines assessed for
     violations by Seller of Environmental Laws as a result of the EPA/DOJ

                                      -34-

<PAGE>

     Action shall constitute Retained Environmental Liabilities and all Costs of
     Compliance incurred by Refinery Buyer or any of its Affiliates in
     connection with the EPA/DOJ Action (other than Retained EPA Compliance
     Costs) shall constitute Assumed Environmental Liabilities.

          (v) If Closing occurs, and if Refinery Buyer receives from the EPA a
     Hardship Waiver in respect of the operation of the Facility for a period to
     or beyond December 31, 2009, then Buyers shall promptly notify Seller of
     such waiver and Buyers shall pay to Seller an amount equal to the Discount
     Amount applied at Closing for purposes of computing the Purchase Price
     pursuant to Section 3.1, together with interest on such Discount Amount at
     a rate equal to the Agreed Rate from the Closing Date to and including the
     date of such payment.

          (b) Restrictions. As used herein, the term "Restricted Property" means
any permit, license, easement, right-of-way, contract or other similar right of
use of real property (other than Environmental Permits, fee interests in land,
and leases of tangible real or personal property) that (i) is contemplated to be
transferred to Refinery Buyer (or to be apportioned or divided) pursuant to this
Agreement or the Related Agreements and (ii) is subject to a Restriction on such
transfer, apportionment or division. As used herein, the term "Restriction"
means any prohibition against, or condition to, or third party consent required
for the transfer, apportionment or division of any right, interest or property
contemplated to be transferred to Refinery Buyer (or to be apportioned or
divided) pursuant to this Agreement or the Related Agreements (including the
consent of Governmental Authorities whose consent is needed for permits to be
issued to Refinery Buyer or modified), which if not satisfied or obtained would
result in a breach of such prohibitions or conditions or would give an outside
party the right to terminate or limit any right of Refinery Buyer or Seller with
respect to such right, interest or property. To Seller's knowledge, all
Restrictions and Restricted Properties affected thereby are set forth in
SCHEDULE 9.3(B). As promptly as practicable after the date of execution of this
Agreement but in any event prior to the Closing date, Seller shall initiate all
procedures which are reasonably required to comply with the Restrictions
relating to the Restricted Properties. If a Restriction exists with respect to a
Restricted Property and is not waived or satisfied prior to Closing, then,
unless such Restriction affects a Restricted Property that is material to the
operation of the Facility or conduct of Seller's Business, without delaying the
Closing or resulting in any reduction in the Purchase Price, any provision
contained in this Agreement or the Related Agreements shall not become effective
with respect to such Restricted Property unless and until such Restriction is
satisfied, waived or no longer applies. Following the Closing, when and if such
a Restriction is so satisfied, waived or no longer applies, to the extent
permitted by Law and any applicable contractual provisions, the assignment of
the Restricted Property subject thereto shall become effective automatically as
of the Closing Date, without further action on the part of Seller or Buyer and
without payment of further consideration. Each of Seller and Refinery Buyer
shall use its commercially reasonable efforts to obtain satisfaction of any
Restriction with respect to a Restricted Property on a timely basis
post-Closing. To the extent that any Restriction with respect to a Restricted
Property exists, Seller shall use its commercially reasonable efforts (without
infringing upon the legal rights of such third party or outside party or
violating any Law) to provide Refinery Buyer with the equivalent assets or
benefits thereof by

                                      -35-

<PAGE>

subcontract or otherwise, at no additional cost to Refinery Buyer (other than
the assumption of any related liability and the performance and compliance by
Refinery Buyer with the terms of such Restricted Property) effective as of the
Closing Date. Refinery Buyer shall bear the economic burden of any related
liability and of the performance and compliance with the terms of each
Restricted Property, at no additional cost to Seller, effective as of the
Closing Date to the same extent as Refinery Buyer would have borne such
liability and other obligations if this Agreement or the Related Agreements, as
the case may be, had been effective as of the Closing Date with respect to such
Restricted Property. In the case of a Contract and to the extent it may do so
without infringing upon the legal rights of such third party or outside party or
violating any Law, Seller shall exercise its rights under such Contract at the
direction and/or for the benefit of Refinery Buyer. Notwithstanding the
foregoing, nothing in this Section 9.3(b) shall require or obligate Refinery
Buyer or Seller to purchase or pay consideration to acquire any new or
additional permit, license, easement, right-of-way, contract or other property
right or interest or to obtain any such third party consent.

          (c) Environmental Permits. Immediately after Closing, Buyers shall
undertake, at their sole cost and expense, all measures necessary to effect the
transfer of all Environmental Permits for the Facility, the Sites and the
McMurrey Pipeline System to Refinery Buyer's or Pipeline Buyer's name (as
appropriate), except as provided below. If there are prohibitions against, or
conditions to, the transfer of any Environmental Permit contemplated to be
transferred to a Buyer pursuant to this Agreement or the Related Agreements
without the prior written consent of third parties, including Governmental
Authorities whose consent is needed for such Environmental Permit to be issued
to a Buyer or modified, which if not satisfied would result in a breach of such
prohibitions or conditions or would give an outside party the right to terminate
or limit any right of a Buyer with respect to any such Environmental Permit,
then, without delaying the Closing or resulting in any reduction in the Purchase
Price, (i) any provision contained in this Agreement or the Related Agreements
shall not become effective with respect to such Environmental Permit and (ii)
Seller, at Buyers' sole cost and expense, shall use reasonable commercial
efforts to assist Buyers in obtaining consent to the transfer of such
Environmental Permit to Buyers or the issuance or modification of such
Environmental Permit in Buyers' name. As an accommodation to Buyers, Seller
shall retain, in its name, all pending applications for permits pursuant to
Title V of the Clean Air Act, Tex. Health & Safety Code Section 382.054, and 30
Tex. Administrative Code Chapter 122 until Buyers have sufficient time to
determine whether they wish to transfer such applications to their name or to
submit new applications in Refinery Buyer's or Pipeline Buyer's name, as
appropriate; provided, however, Buyers shall (i) bear all costs related to
Seller's maintaining and continuing prosecution of such applications; and (ii)
within six months after Closing, Buyers shall have requested transfer of such
applications to Refinery Buyer's or Pipeline Buyer's name (as appropriate) or
shall have submitted new applications for such Title V permits in Refinery
Buyer's or Pipeline Buyer's name (as appropriate). Nothing in this Section
9.3(c) shall in any way affect Buyers' obligations in this Agreement, including,
without limitation, their obligation to comply with Environmental Law and to
indemnify the Seller Indemnitees for Assumed Environmental Liabilities related
thereto. Further, until all pending Title V permit applications are transferred
to Refinery Buyer's or Pipeline Buyer's name (as appropriate) or Buyers submit
new applications for such Title V permits in their own name, Buyers shall notify
Seller in writing of all instances of deviations, as

                                      -36-

<PAGE>

defined in 30 Texas Administrative Code Chapter 122, within 10 Business Days of
the occurrence of each deviation at the Facility, the Sites and the McMurrey
Pipeline System, and, in accordance with the provisions of Section 15.2, Buyers,
jointly and severally, shall indemnify, hold harmless and defend the Seller
Indemnitees from and against any and all Environmental Fines and Environmental
Liabilities incurred by Seller resulting from or relating to Buyers' failure to
provide such notice to Seller. Refinery Buyer shall immediately after Closing
undertake, at its sole cost, all measures necessary to effect and obtain
approval of the transfer to Refinery Buyer of Landfill Post Closure Care Permit
No. HW-50062-000. The Parties recognize that the transfer of said permits may
not take place for at least 90 days after Refinery Buyer submits the application
for transfer. Notwithstanding the above and subject to Section 9.7, Refinery
Buyer shall comply with all obligations of said permits and indemnify, hold
harmless and defend the Seller Indemnitees from and against any and all
Environmental Fines and Environmental Liabilities resulting from failure by
Refinery Buyer to so comply or resulting from the failure to transfer before
Closing the Environmental Permits described in this Section.

          (d) Cooperation. Seller and Buyers shall cooperate in obtaining any
required consents and permits to permit the transactions contemplated by this
Agreement. Buyers shall take the primary role in obtaining any Environmental
Permits and the transfer of technology licenses, and Seller shall take the
primary role in obtaining consents to the transfer of Contracts other than
technology licenses.

          (e) HSR Act. Seller and Buyers shall, within three (3) Business Days
after signing this Agreement, file all materials required to be filed by it
under the HSR Act with respect to the transactions contemplated hereby, and
shall promptly file any supplemental materials required and shall use their
commercially reasonable efforts to comply in all material respects with the
requirements of the HSR Act in respect of such transactions. Seller and Buyers
shall request early termination of the HSR Act waiting period. The filing fees
payable in connection with the filings required by the HSR Act in connection
with the transactions contemplated hereby shall be borne by Buyers.

          Section 9.4 Records. Within a reasonable period of time following the
Closing, Seller shall make all Asset Records (not located at the Sites)
available for delivery to Buyers at Seller's offices in Tyler, Texas, or at the
locations of the Assets in the case of Asset Records maintained at such
locations, except for Asset Records Seller reasonably believes it will need in
connection with providing transition services in accordance with the Transition
Services Agreement, which Asset Records Seller shall deliver to Buyers promptly
after such transition services are completed. Buyers shall maintain all Asset
Records and (except to the extent constituting Excluded Assets) Company Records
until the fifth anniversary of the Closing Date (or for such longer period of
time as Seller shall advise Buyers is necessary in order to have the Asset
Records and such Company Records available with respect to open years for Tax
audit purposes), or, if any of the Asset Records or such Company Records pertain
to any claim or dispute pending on the fifth anniversary of the Closing Date,
Buyers shall maintain any of the Asset Records or such Company Records
designated by Seller until such claim or dispute is finally resolved and the
time for all appeals has been exhausted. Buyers shall provide (or cause Newco to
provide) Seller and its Representatives reasonable access to and the right, at
Seller's

                                      -37-

<PAGE>

expense, to copy the Asset Records and (except to the extent constituting
Excluded Assets) Company Records for the purposes of (i) preparing and
delivering any accounting provided for under this Agreement and adjusting,
prorating and settling the charges and credits provided for in this Agreement,
(ii) complying with any Law affecting Seller's interest in the Assets, the
Company Shares or the Newco Shares prior to the Closing Date, (iii) conducting
and preparing any audit of the books and records of any third party relating to
Seller's interest in the Assets, the Company Shares or the Newco Shares prior to
the Closing Date, or responding to any audit conducted or prepared by such third
parties, (iv) preparing Tax returns, (v) responding to or disputing any Tax
audit or (vi) asserting, defending or otherwise dealing with any claim or
dispute under this Agreement or with respect to the Assets, the Company Shares
or the Newco Shares. In no event shall Buyers, Land Newco, Pipeline Newco or any
of Buyers' Affiliates destroy any Asset Records or Company Records without
giving Seller sixty (60) days' advance written notice thereof and the
opportunity, at Seller's expense, to obtain such Asset Records or Company
Records prior to their destruction.

          Section 9.5 Recording. Immediately following the Closing, Refinery
Buyer, at its cost and expense, shall record the Deed (and such other
instruments of assignment with respect to the Assets as Refinery Buyer or Seller
may elect) in the appropriate governmental offices of the jurisdictions in which
the Assets are located and in any other locations and records in which
recordation is required or advisable. Promptly following such recording,
Refinery Buyer shall advise Seller in writing of the pertinent recording data.

          Section 9.6 Casualty and Condemnation.

          (a) Material Casualty. If after the date of this Agreement and prior
to the Closing, all or any part of the Assets or McMurrey Pipeline System is
damaged or destroyed by fire or other casualty and such damage or destruction
has a Material Adverse Effect, Buyers shall have the option, exercisable within
thirty (30) days after receiving written notice thereof from Seller (and the
date for Closing shall be deemed extended to the extent necessary for Buyers to
have such full, thirty (30) day election period), to elect by written notice to
Seller to terminate this Agreement; provided, however, that such election by
Buyers to terminate this Agreement shall not be effective if

          (i) such damaged or destroyed Assets or McMurrey Pipeline System can
     be repaired or replaced to the state in which they existed immediately
     preceding such damage or destruction within 120 days from the date of
     Seller's receipt of Buyers' notice of termination, and

          (ii) within ten (10) days after Seller's receipt of Buyers' notice of
     termination, Seller gives Buyers written notice of Seller's election to
     repair or replace such damaged or destroyed Assets or McMurrey Pipeline
     System at Seller's sole expense (including any insurance proceeds
     attributable thereto under insurance policies of Seller or its Affiliates).

If Seller elects to repair or replace such damaged Assets or McMurrey Pipeline
System pursuant to the foregoing, Seller shall be obligated to proceed in good
faith to diligently repair or replace

                                      -38-

<PAGE>

such damaged or destroyed Assets or McMurrey Pipeline System to the state in
which the same existed immediately preceding such damage or destruction and the
Closing Date shall be extended until the third Business Day following the date
on which Seller and Buyers mutually agree that such damaged Assets or McMurrey
Pipeline System have been so repaired or replaced, such mutual agreement not to
be unreasonably withheld, conditioned or delayed; provided, however, this
Agreement shall terminate, at Buyers' option, if such damaged Assets or McMurrey
Pipeline System are not so repaired or replaced within 120 days from the date of
Seller's receipt of Buyers' aforesaid notice of termination.

          (b) Material Condemnation. If after the date of this Agreement and
prior to the Closing, all or any part of the Assets or McMurrey Pipeline System
is taken in condemnation or if proceedings for such purpose shall be pending or
threatened, and (disregarding payment received for the condemnation) such taking
or threatened taking has (or would, when completed, have) a Material Adverse
Effect, then Buyers shall have the option, exercisable within thirty (30) days
after receiving written notice thereof from Seller with a reasonable description
of the pending or threatened taking (and the date for Closing shall be deemed
extended to the extent necessary for Buyers to have such full, thirty (30) day
election period), to elect by written notice to Seller to terminate this
Agreement.

          (c) Other Casualty and Condemnation. If after the date of this
Agreement and prior to the Closing

          (i) all or any part of the Assets or McMurrey Pipeline System shall be
     damaged or destroyed by fire or other casualty and either (1) such damage
     or destruction does not have a Material Adverse Effect or (2) Buyers do not
     elect to terminate this Agreement pursuant to Section 9.6(a), or

          (ii) all or any part of the Assets or McMurrey Pipeline System shall
     be taken in condemnation or under the right of eminent domain or if
     proceedings for such purposes shall be pending or threatened and either (1)
     such taking or threatened taking does not have a Material Adverse Effect or
     (2) Buyers do not elect to terminate this Agreement pursuant to Section
     9.6(b),

this Agreement shall remain in full force and effect notwithstanding any such
damage, destruction, taking or proceeding or the threat thereof. To the extent
insurance proceeds (excluding any insurance proceeds payable from Affiliates of
Seller or through self-insurance programs of Seller or its Affiliates),
condemnation awards or other payments are not committed, used or applied by
Seller prior to the Closing Date to repair, restore or replace such damaged,
destroyed or taken Assets or McMurrey Pipeline System, Seller shall at the
Closing (i) assign to Buyers Seller's right to receive all insurance or
condemnation proceeds, awards or payments (excluding any insurance proceeds
payable from Affiliates of Seller or through self-insurance programs of Seller
or its Affiliates) owed to Seller by reason of such damage, destruction or
taking, less any reasonable costs and expenses incurred by Seller in collecting
same or in connection with such proceedings or the threat thereof, and (ii) pay
to Buyers all insurance or condemnation proceeds, awards or payments (excluding
any insurance proceeds payable from

                                      -39-

<PAGE>

Affiliates of Seller or through self-insurance programs of Seller or its
Affiliates) theretofore paid to Seller by reason of such damage, destruction or
taking, less any reasonable costs and expenses incurred by Seller in collecting
same or in connection with such proceedings or the threat thereof.
Notwithstanding the foregoing, nothing in this Section shall give Buyers any
interest in or right to receive any insurance proceeds payable from Affiliates
of Seller or through self-insurance programs of Seller or its Affiliates.

          Section 9.7 Release and Replacement of Bonds, Guarantees, etc. At the
Closing, (i) Buyers shall deliver to the applicable beneficiary replacement or
substitute guaranties, letters of credit, bonds, and other security obligations
for those set forth on SCHEDULE 9.7 (the "Existing Credit Support") and (ii)
Buyers, in form and substance acceptable to Seller, shall have caused the
release as of the Closing Date of Seller and its Affiliates from all obligations
and liabilities relating to such Existing Credit Support. In this regard, at
Closing or upon transfer of the permit referred to below, if later, Buyers shall
establish the financial assurance required by Landfill Post Closure Care Permit
No. HW-50062-000 and shall provide Seller written notice that the financial
assurance is in place and a copy of the letter of credit, bond or other
mechanism used to satisfy the financial assurance requirement. In this
connection, upon Refinery Buyer's request reasonably in advance of the date upon
which such permit transfer is to occur, and subject to Seller's obtaining the
prior written consent of the insurer, (a) Seller shall assign to Refinery Buyer
all of Seller's rights and interests in, to and under that certain Closure and
Post-Closure Insurance Policy dated December 29, 2003, issued by Allianz Global
Risks US Insurance Company (Policy No. CGL 2001229) and (b) concurrently with
such assignment and in consideration therefor, Refinery Buyer shall pay to
Seller, by wire transfer of immediately available funds, an amount equal to the
sum of (x) the Deposit amount plus the Interest Credit accrued thereon through
the date of such permit transfer, and (y) the then unamortized portion of the
prepaid premium for such policy calculated as of the date on which such permit
transfer occurs.

          Section 9.8 Crown Central Name, Logos, etc. Following the Closing,
Buyers will not be entitled to use (a) the names "Crown," "Crown Central", or
any variations and derivations thereof (including any logo, trademark or design
containing such name) or (b) any logo, service mark, copyright, name or
trademark which constitutes an Excluded Asset. Accordingly, as soon as
reasonably practicable, but in any event within three months following the
Closing, Buyers will remove or paint over, as appropriate, any logo, service
mark, trade name or trademark which constitutes an Excluded Asset and is on any
of the Assets or the Company's Assets.

          Section 9.9 Tax Matters.

          (a) Transfer Taxes and Federal Excise Taxes.

          (i) Buyers shall be responsible for (1) any sales, excise or use Taxes
     which may become due and owing by reason of sale of any property to Buyers
     contemplated pursuant to this Agreement and (2) all transfer, stamp,
     documentary and similar Taxes imposed on the parties hereto with respect to
     all transfers of property to Buyers

                                      -40-

<PAGE>

     contemplated pursuant to this Agreement. The Taxes referred to in the
     preceding sentence shall be paid by Buyers when due and Buyers, at Buyers'
     expense, shall file all necessary Tax returns and other documentation with
     respect to all such transfer, documentary, sales, excise, use, stamp and
     other Taxes, and, if required by Law, Seller will, and will cause its
     Affiliates to, join in the execution of any such Tax returns and other
     documentation with respect thereto.

          (ii) At Closing, Refinery Buyer shall execute and deliver to Seller
     (1) a Texas Resale Certificate with respect to the Inventory in form and
     substance reasonably satisfactory to Seller and (2) a Texas Sales and Use
     Tax Exemption Certificate with respect to all of that portion of the Assets
     qualifying for the exemption for property used in manufacturing under Texas
     Tax Code Section 151.318 and Comptroller's Sales Tax Rule 3.300 in form and
     substance reasonably satisfactory to Seller.

          (iii) At the Closing, Refinery Buyer shall deliver to Seller
     documentation in form and substance reasonably satisfactory to Seller (1)
     evidencing that Refinery Buyer is appropriately registered under Section
     4101 of the Code for purposes of the federal excise Taxes imposed by
     Sections 4041(a)(1), 4081 and 4091 of the Code, and (2) that is required by
     applicable Law to substantiate that the consummation of the transactions
     contemplated by this Agreement are not subject to such federal excise
     Taxes, including a notification certificate or certificates under Treas.
     Reg. Section 48.4081-5. Notwithstanding anything contained in this
     Agreement to the contrary or any provision of Law imposing the burden of
     federal excise Taxes on Seller, Buyers or both, Buyers shall be responsible
     for, and shall, in accordance with the provisions of Section 15.2,
     indemnify and hold Seller harmless from, any and all federal excise Taxes
     imposed in connection with the consummation of the transactions
     contemplated by this Agreement.

          (iv) At or prior to Closing, Seller shall deliver to Buyers one or
     more certificates from the Texas Comptroller of Public Accounts issued
     under Section 111.020 of the Texas Tax Code to the effect that no Taxes are
     due from Seller under Title 2 of the Texas Tax Code.

          (b) Company Taxes.

          (i) Seller has caused or will cause each of the Company, Land Newco
     and Pipeline Newco to be included in the consolidated federal income Tax
     Returns of the applicable Seller Group (and the state income Tax Returns of
     any state that permits consolidated, combined or unitary income Tax
     Returns, if any, of an applicable group or groups of corporations which
     includes or include the Company and/or Land Newco and Pipeline Newco, on
     the one hand, and one or more members of the applicable Seller Group, on
     the other hand), for each taxable period or portion thereof ending on or
     before the Closing Date, has caused or shall cause such Tax Returns to be
     timely filed with the appropriate taxing authorities and shall be
     responsible for the timely payment (and shall be entitled to any refunds
     including any interest thereon) of all Taxes due with respect to the
     periods covered by such Tax Returns. The portions of such Tax Returns
     relating to

                                      -41-

<PAGE>

     the Company shall be prepared in a manner consistent with prior practice,
     except as required by a change in applicable Law.

          (ii) With respect to each Tax Return covering a taxable period ending
     on or before the Closing Date that is required to be filed after the
     Closing Date with respect to Land Newco and/or Pipeline Newco and that is
     not described in Section 9.9(b)(i) above, Buyers shall cause such Tax
     Return to be prepared in a manner consistent with prior practice, except as
     required by a change in applicable Law, and not later than 30 days prior to
     the due date of such Tax Return, Buyers shall deliver a copy of such Tax
     Return to Seller for its review.

          (iii) With respect to each Tax Return covering a taxable period
     beginning on or before the Closing Date and ending after the Closing Date
     (a "Straddle Period") that is required to be filed after the Closing Date
     with respect to Land Newco and/or Pipeline Newco and that is not described
     in Section 9.9(b)(i) above, Buyers shall cause such Tax Return to be
     prepared in a manner consistent with prior practice, except as required by
     a change in applicable Law, and Buyers shall determine (by an interim
     closing of the books as of the Closing Date except for franchise Taxes and
     ad valorem Taxes which shall be apportioned on a daily basis between Buyers
     and Seller in accordance with Section 9.9(b)(vi) and the method specified
     in Section 12.1 with respect to the Assets, respectively) the Tax which
     would have been due with respect to the period covered by such Tax Return
     if such taxable period ended on and included the Closing Date (the
     "Pre-Closing Tax"). Not later than 30 days prior to the due date of such
     Tax Return, Buyers shall deliver a copy of such Tax Return, together with a
     statement ("Statement") showing Buyers' determination of the Pre-Closing
     Tax with respect to such Tax Return, to Seller for its review.

          (iv) The amount of Taxes shown to be due on any Tax Return described
     in Section 9.9(b)(ii) above, or on any Tax Return described in Section
     9.9(b)(iii) and the Statement related thereto, shall be final and binding
     upon the parties hereto, unless Seller shall have delivered to Buyers,
     within ten calendar days after the date of Seller's receipt of such Tax
     Return and, if applicable, such Statement, a written report containing all
     changes that Seller proposes to make to such Tax Return and, if applicable,
     such Statement. Buyers and Seller shall undertake in good faith to resolve
     any issues raised in any such report prior to the due date (including any
     extension thereof) for filing such Tax Return and mutually to consent to
     the filing of such Tax Return and, if applicable, to agree on the
     determination to be set forth in the Statement related thereto, in which
     case the information and total amount of Taxes shown to be due on such
     agreed Tax Return and, if applicable, shown on such agreed Statement shall
     be final and binding on the Parties absent manifest error. In the event
     Seller and Buyers are unable to resolve any dispute by the earlier of (1)
     ten calendar days after the date of Buyers' receipt of written notice from
     Seller setting forth Seller's proposed resolution of such dispute, or (2)
     ten calendar days prior to the due date for filing of the Tax Return in
     question (including any extension thereof), Seller and Buyers shall jointly
     engage the Independent Arbitrator to make its independent determination
     with respect to the item or items in dispute and the

                                      -42-

<PAGE>

     amount or amounts related thereto. If the Independent Arbitrator is
     engaged, Seller and Buyers shall provide, or cause to be provided, the
     Independent Arbitrator with all books, records and other information
     relevant to the determination of the disputed items and the Independent
     Arbitrator shall be instructed to make its determination as soon as
     possible. The determination of the Independent Arbitrator shall be final
     and binding on the Parties absent manifest error. In any case where a
     disputed item has not been resolved (either by mutual agreement of the
     Parties or by a determination of the Independent Arbitrator) prior to the
     due date (including any extension thereof) for filing such Tax Return, then
     Buyers may resolve such item as they shall determine in their sole
     discretion and cause such Tax Return to be filed on the due date (including
     any extension thereof) for filing such Tax Return without the Parties'
     mutual agreement or consent of Seller. Notwithstanding the filing of such
     Tax Return, (x) the Independent Arbitrator shall make a determination with
     respect to any such disputed item, and (y) the amount of Taxes determined
     to be due with respect to such Tax Return and, if applicable, determined to
     be properly set forth on the Statement related to such Tax Return, shall be
     the amount of Taxes that would have been due on such Tax Return and, if
     applicable, be the amount of Taxes that would be properly set forth on the
     Statement related to such Tax Return, after giving effect to the
     Independent Arbitrator's determination. The fees and expenses of the
     Independent Arbitrator shall be borne by Seller and Buyers in inverse
     proportion as they may prevail on matters resolved by the Independent
     Arbitrator, which proportionate allocations shall also be determined by the
     Independent Arbitrator at the time the determination of the Independent
     Arbitrator is rendered on the merits of the matters submitted. All other
     costs and expenses incurred by each Party in connection with the matters
     submitted by the Independent Arbitrator, including attorney's fees and
     accountant's fees, shall be borne by the Party incurring same.

          (v) In the case of each Tax Return described in Section 9.9(b)(ii) or
     (iii), not later than the later of (i) five calendar days before the due
     date for payment of Taxes with respect to such Tax Return, or (ii) in the
     event of a dispute, five calendar days after the resolution thereof either
     by mutual agreement of the Parties or by the Independent Arbitrator, Seller
     shall cause to be paid to Buyers an amount equal to the total amount of
     Taxes shown as due on such Tax Return or the Statement relating to such Tax
     Return (in each case net of any payments made prior to the Closing Date in
     respect of such Taxes, whether as estimated Taxes or otherwise), as the
     case may be, or, in the event Seller has timely proposed that changes be
     made to such Tax Return and, if applicable, such Statement, the total
     amount of Taxes that is shown or would have been shown as due on such Tax
     Return or the Statement relating to such Tax Return after giving effect to
     the Parties' mutual agreement or the Independent Arbitrator's determination
     (in each case net of any payments made prior to the Closing Date in respect
     of such Taxes, whether as estimated Taxes or otherwise), as the case may
     be.

          (vi) Notwithstanding anything to the contrary herein, any franchise
     Tax paid or payable with respect to Land Newco and/or Pipeline Newco shall
     be allocated to the period (a "Privilege Period") with respect to which the
     right to do business is obtained by the payment of such franchise Tax. With
     respect to each franchise Tax Return covering a

                                      -43-

<PAGE>

     Privilege Period beginning on or before the Closing Date and ending after
     the Closing Date, 100% of the franchise Taxes due with respect to such Tax
     Return and Privilege Period shall be apportioned to Buyers with Buyers
     being obligated to pay all of such franchise Taxes.

          (vii) Seller shall have the right to all refunds of Taxes (including
     interest thereon) which relate to (i) Taxes of the Company or Land Newco
     and/or Pipeline Newco for periods or portions thereof ending on or before
     the Closing Date and (ii) to the extent provided in the next sentence,
     Taxes of Land Newco and/or Pipeline Newco for Straddle Periods. To the
     extent any refund of Taxes (including interest thereon) relates to a
     Straddle Period of Land Newco and/or Pipeline Newco, such refund shall be
     apportioned between Buyers and Seller based on the appropriate allocation
     method set forth in Section 9.9(b)(iii), Section 9.9(b)(vi) or Section
     12.1. Buyers shall pay over to Seller any such refunds within ten calendar
     days of receipt thereof.

          (viii) Buyers and Seller shall cooperate fully, and shall cause Land
     Newco and Pipeline Newco to cooperate fully, as and to the extent
     reasonably requested by the other Party, in connection with the filing of
     Tax Returns pursuant to this Section 9.9 and any audit, litigation or other
     proceeding (each a "Proceeding") with respect to Taxes. Such cooperation
     shall include the retention and (upon the other Party's request) the
     provision of records and information which are reasonably relevant to any
     such Proceeding and making employees available on a mutually convenient
     basis to provide additional information and explanation of any material
     provided hereunder. Buyers will, and will cause Land Newco and Pipeline
     Newco, to retain all books and records with respect to Tax matters
     pertinent to Land Newco and/or Pipeline Newco relating to any taxable
     period beginning before the Closing Date until the later of six years after
     the Closing Date or the expiration of the applicable statute of limitations
     of the respective taxable periods, and to abide by all record retention
     agreements entered into with any Taxing Authority. Buyers and Seller
     further agree, upon request, to provide the other Party with all
     information regarding Land Newco and Pipeline Newco that either Party may
     be required to report to any taxing authority.

          (c) Section 338(h)(10) Elections. Seller agrees that, if requested in
writing by Land Buyer and/or Pipeline Buyer on or before the date that is 90
days after the Closing Date, Seller will cause CCLLC to join Land Buyer and/or
Pipeline Buyer (as appropriate) in making a timely, irrevocable and effective
election under section 338(h)(10) of the Code with respect to the purchase of
the Land Newco Shares and/or Pipeline Newco Shares (the "Section 338(h)(10)
Election") and a similar election under the applicable income tax laws of such
of the states as Land Buyer or Pipeline Buyer may request (collectively the
"Section 338(h)(10) State Elections"). Land Buyer and/or Pipeline Buyer will
prepare and deliver to Seller an Internal Revenue Service Form 8023 and any
similar forms under applicable state income tax law (the "Forms") and the
schedules required to be attached thereto which Forms shall have been duly
executed by an authorized person for Land Buyer and/or Pipeline Buyer. Provided
that the information on such Forms is, in the reasonable determination of
Seller, correct and complete in all material respects, Seller shall cause the
Forms to be duly executed by an authorized person

                                      -44-

<PAGE>

for CCLLC and shall return the Forms to Land Buyer and/or Pipeline Buyer (as
appropriate) in time to allow Land Buyer and/or Pipeline Buyer (as appropriate)
to duly and timely file the Forms as prescribed by Treasury Regulation
1.338(h)(10)-l or the corresponding provisions of applicable state income tax
law and Land Buyer and/or Pipeline Buyer (as appropriate) shall provide written
evidence and notification of the filing of the Forms to Seller. If Land Buyer
and/or Pipeline Buyer requests that the Section 338(h)(10) Election be made, the
Parties shall, as promptly as reasonably practicable following such request,
cooperate and consult with each other in order to reach a mutually acceptable
agreement regarding the allocation of the "modified aggregate deemed sales
price" (as defined under applicable Treasury Regulations) among the assets of
Land Newco and/or Pipeline Newco (as appropriate) (which allocation shall be
consistent with the allocation of that portion of the Purchase Price allocated
to the Land Newco Shares and/or Pipeline Newco Shares (as appropriate) pursuant
to Section 3.6). If after such allocation is agreed upon any adjustment is made
to such "modified aggregate deemed sales price" as a result of any adjustment to
the portion of the Purchase Price allocated to the Land Newco Shares and/or
Pipeline Newco Shares pursuant to Section 3.6, the Parties shall cooperate and
consult with each other in order to reach a mutually acceptable agreement
regarding the appropriate adjustment to be made to the theretofore agreed upon
allocation of the "modified aggregate deemed sales price." The Parties shall not
take a federal or state Tax reporting position inconsistent with such mutually
agreed upon allocation of the "modified aggregate deemed sales price."

          Section 9.10 Employee Benefits.

          (a) Employee Matters. Refinery Buyer (in the case of Seller's
employees) and Refinery Buyer or Pipeline Buyer (in the case of the Company's
employees) shall offer in writing, effective as of Closing, employment to all of
Seller's and the Company's employees identified in SCHEDULE 9.10(A) (the
"Personnel") as of the Closing. The Personnel who accept offers of employment of
such Buyer made prior to the Closing shall hereinafter be referred to as the
"Transferred Employees". All employment offers made to the Personnel pursuant to
this Section 9.10 shall be made sufficiently in advance of the Closing so as to
give the Personnel reasonable time to evaluate the offers (and in no event less
than 15 days prior to the Closing Date) and shall be Comparable Offers. Buyers
shall furnish to Seller copies of such offers made to such Personnel promptly
upon delivery thereof to such Personnel. Buyers shall recognize Paper
Allied-Industrial, Chemical and Energy Workers International Local Union
AFL-CIO-CLC (the "PACE Local 4-202 Union") as the exclusive employees'
representative of the Personnel members who are included in each unit of
employees covered under the collective bargaining agreements between the PACE
Local 4-202 Union and Seller and all memoranda of agreement listed on SCHEDULE
4.1(R) (the "PACE Local 4-202 Labor Agreements"). Effective as of the Closing,
Refinery Buyer shall adopt and assume all of Seller's obligations (excluding any
obligations that accrued prior to the Closing, except to the extent otherwise
expressly provided in this Agreement) under the PACE Local 4-202 Labor
Agreements. All obligations of Refinery Buyer under this Section 9.10 shall be
binding upon any Affiliate of Refinery Buyer who acquires the Facility or any
material portion of the Assets at the Closing, and Refinery Buyer shall cause
any Affiliate of Refinery Buyer who acquires the Facility or a material portion
of the Assets (whether from Refinery Buyer or a successor or assign of Refinery
Buyer) at the Closing

                                      -45-

<PAGE>

to expressly assume and agree to perform such obligations and to make Seller an
express third party beneficiary of such assumption and agreement.

          (b) General Employee Benefit Matters. Effective as of the Closing, and
for at least one year after the Closing Date, Refinery Buyer and Pipeline Buyer
shall maintain for the benefit of the Transferred Employees employee benefit
programs that are reasonably comparable in the aggregate to the employee benefit
programs that Seller and its ERISA Affiliates maintained for the benefit of such
Transferred Employees immediately prior to the Closing (other than any severance
plans or severance payments or arrangements, which Buyers shall not be obligated
to provide or maintain), subject to the provisions of Section 9.10(c) and
9.10(d).

          (c) Severance Pay. Refinery Buyer and Pipeline Buyer shall cause each
Transferred Employee to be paid severance benefits if within 12 months after the
Closing Date, any such Buyer or its Affiliate reduces the Transferred Employee's
base pay and the Transferred Employee elects within 30 days thereof to terminate
his employment with such Buyer and its Affiliates or the Transferred Employee's
employment is terminated by such Buyer or its Affiliate unless the termination
of employment qualifies as a "Termination for Cause". Such severance benefits
shall be no less than the severance benefits specified on SCHEDULE 9.10(C).
"Termination for Cause" as used in this paragraph shall mean termination from
employment due to gross negligence, misuse or unauthorized appropriation of
trade secrets or other confidential information of such Buyer or any of its
Affiliates, theft of property from such Buyer or any of its Affiliates, willful
damage to such Buyer's or any of its Affiliates' property, or any material
failure by the employee to perform any term or condition of his employment with
such Buyer or its Affiliate.

          (d) Seller's Employee Plans and Benefit Arrangements. As of the
Closing Date, Transferred Employees shall cease to accrue or enjoy benefits
under the Seller Employee Benefit Plans and shall commence accrual of benefits
and participation in those compensation and employee benefit plans and benefit
arrangements maintained by Refinery Buyer and Pipeline Buyer or Buyers' ERISA
Affiliates in which they are eligible to participate. Refinery Buyer or Pipeline
Buyer or Buyers' ERISA Affiliate shall establish or maintain a qualified 401(k)
plan (the "Buyer's Savings Plan") in which the Transferred Employees will be
eligible to participate immediately following the Closing Date. As soon as
administratively possible following the Closing Date, Seller shall provide each
Transferred Employee the opportunity to transfer his or her benefits and
liabilities, including loans, in the Seller's Savings Plan to the Buyer's
Savings Plan. Seller, Refinery Buyer and Pipeline Buyer agree to take all steps
necessary such that a transfer, if elected by a Transferred Employee, shall meet
all requirements stated in Treasury Regulations section 1.411(d)-4, Q&A 3(b).

          (e) Necessary Actions. Seller, Refinery Buyer and Pipeline Buyer shall
take all actions which may be necessary in order to effectuate the transactions
contemplated by this Section 9.10, including, without limitation, adopting any
necessary amendments to the employee benefit plans and benefit arrangements and
making all necessary filings and submissions to the appropriate governmental
agencies.

                                      -46-

<PAGE>

          (f) Indemnification by Buyers. Refinery Buyer and Pipeline Buyer,
jointly and severally, shall indemnify, defend and hold harmless (i) Seller,
(ii) each ERISA Affiliate of Seller, (iii) each Seller Employee Benefit Plan,
and (iv) the fiduciaries of each such Seller Employee Benefit Plan from and
against any and all liabilities of any kind or nature, caused by, resulting from
or arising in connection with:

          (i) the sponsorship, operation or administration on and after the
     Closing Date of, and the payment of benefits to Transferred Employees under
     any employee benefit plan and benefit arrangement of Refinery Buyer and
     Pipeline Buyer or any of their Affiliates as set forth hereunder; and

          (ii) any breach of any covenant or agreement regarding employee
     benefit matters made in this Agreement.

          Section 9.11 Accounts Receivable and Accounts Payable.

          (a) Seller shall cause all accounts payable and all accounts
receivable of the Company relating to Seller or any Affiliate of Seller to be
cancelled or fully satisfied prior to Closing. Without limiting the foregoing,
Seller shall cause any of such accounts payable of the Company to be offset
against any such accounts receivable and, to the extent such accounts payable
exceed such accounts receivable, Seller shall either contribute such accounts
payable to the capital of the Company or shall cause an amount equal thereto to
be contributed to the capital of the Company, in which case it then shall cause
the Company to immediately pay such amounts in full.

          (b) Seller shall cause the Company, prior to Closing, to distribute to
its shareholder as a dividend all other accounts receivable of the Company as of
Closing.

          (c) Seller shall pay in full prior to Closing all other accounts
payable of the Company as of Closing or, if it does not do so, Seller shall make
a contribution to the capital of the Company at Closing in an amount equal to
all unpaid accounts payable of the Company as of Closing.

          (d) If it is determined, after Closing, that the Company at Closing
had any accounts payable other than those which were paid in full by Seller or
for which a capital contribution was made pursuant to Section 9.11, then Buyers
shall provide Seller prompt written notice thereof and Seller shall pay Buyers,
by wire transfer of immediately available funds, an amount equal to such
accounts payable plus interest thereon at the Agreed Rate from the Closing until
the date of payment.

          Section 9.12 Insurance. Until the Closing, Seller shall maintain and
cause the Company to maintain the Insurance Policies in full force and effect.
Notwithstanding the foregoing, if any Insurance Policy ceases to be in full
force and effect prior to Closing, Seller shall immediately replace (or cause
the Company to replace) such Insurance Policy with a policy

                                      -47-

<PAGE>

affording substantially the same insurance coverage with a financially sound and
reputable insurance carrier.

          Section 9.13 Amendment of Schedules. At all times prior to the Closing
Date, all Schedules hereto shall be amended and supplemented as promptly as
practicable to include reference to any matter relating to Seller, Seller's
Business, the Assets, the Company Shares, the Company or the Company's Assets
which arises or occurs after the date hereof and does not result from a breach
by Seller of Section 9.1.

          Section 9.14 Closing Deposit.

          (a) Subject to the terms and conditions set forth in this Section
9.14, on the Closing Date Buyers shall cause a portion of the Adjusted Purchase
Price in the amount of $5,000,000.00 (the "Closing Deposit") to be deposited
with the Escrow Agent pursuant to the terms and provisions of an escrow
agreement by and among Buyers, Seller and the Escrow Agent substantially in the
form attached hereto as EXHIBIT 9.14 (the "Closing Deposit Escrow Agreement").
For income tax purposes, Seller shall include in its income any interest,
dividends and other amounts earned on the Closing Deposit ("Closing Deposit
Escrow Earnings") prior to disbursement of the Closing Deposit to Seller. The
Closing Deposit shall be held and distributed by the Escrow Agent in accordance
with the terms and provisions of the Closing Deposit Escrow Agreement. If the
Closing occurs, Buyers agree to provide written notice to Seller of any intent
to withdraw from the Closing Deposit to satisfy any claims of Buyers for
indemnification under Section 15.1 of this Agreement; and if Seller fails,
within thirty (30) days following receipt of such notice from Buyers, to provide
joint written instructions to the Escrow Agent to allow Buyers to withdraw such
funds from the Closing Deposit, then Buyers may submit the dispute to be
resolved by dispute resolution set forth in Section 16.12. On the date of any
distribution to Seller by the Escrow Agent of funds from the Closing Deposit,
the Escrow Agent shall distribute to Seller the Closing Deposit Escrow Earnings
on such distribution. Seller's liability for indemnification under Section 15.1
of this Agreement shall not be limited to the Closing Deposit. Upon Closing,
Buyers agree to seek recovery for Buyers' claims for indemnification under
Section 15.1 of this Agreement against the Closing Deposit to the extent such
claims do not exceed the Closing Deposit. To the extent such claims exceed the
Closing Deposit, Seller shall be liable therefor in accordance with the
applicable provisions of Section 15.1 of this Agreement. Subject to and in
accordance with the provisions of the Closing Deposit Escrow Agreement, the
Closing Deposit shall be distributed to Seller in installments, at the indicated
times, as follows:

          (i) upon the expiration of eighteen months after the Closing Date, an
     amount equal to the positive difference, if any, of $2,000,000.00 minus the
     sum of (1) all Distributions, if any, made prior to such date and (2) the
     aggregate dollar amount of all Unresolved Buyer Claims, if any, existing as
     of the expiration of such eighteen-month period; and

          (ii) upon the expiration of thirty months after the Closing Date, an
     amount equal to the positive difference, if any, of $5,000,000.00 minus the
     sum of (1) all Distributions made prior to such date and (2) the aggregate
     dollar amount of all

                                      -48-

<PAGE>

     Unresolved Buyer Claims, if any, existing as of the expiration of such
     thirty-month period.

For purposes of this Section 9.14, "Distribution" shall mean any portion of the
Closing Deposit distributed to Seller or Buyers in accordance with the Closing
Deposit Escrow Agreement; and "Unresolved Buyer Claims" shall mean claims by any
Buyer under Section 15.1 of this Agreement with respect to which a determination
of whether indemnification by Seller under Section 15.1 is owed has not then
been made.

          (b) In the event of a breach by Buyers of any of the covenants
contained in Section 9.16 and the failure by Buyers to cure the same within 30
days after receipt by Buyers of written notice from Seller of such breach, then
(and without limiting any other rights or remedies of Seller on account of such
breach or failure) Buyers shall, upon demand by Seller, provide joint written
instructions to the Escrow Agent to allow Seller to withdraw the entire Closing
Deposit together with all Closing Deposit Escrow Earnings thereon, or such
amount thereof as may remain in the Closing Deposit escrow account at the time
of such demand.

          Section 9.15 Buyer Deposit.

          (a) Subject to the terms and conditions set forth in this Section
9.15, on the Closing Date Buyers shall cause the amount of $5,000,000.00 (the
"Buyer Deposit") to be deposited with the Escrow Agent pursuant to the terms and
provisions of an escrow agreement by and among Buyers, Seller and the Escrow
Agent substantially in the form attached hereto as Exhibit 9.15 (the "Buyer
Deposit Escrow Agreement"). For income tax purposes, Refinery Buyer shall
include in its income any interest, dividends and other amounts earned on the
Buyer Deposit. The Buyer Deposit shall be held and distributed by the Escrow
Agent in accordance with the terms and provisions of the Buyer Deposit Escrow
Agreement. If the Closing occurs, Seller agrees to provide written notice to
Buyers of any intent to withdraw from the Buyer Deposit to satisfy any claims of
Seller for indemnification under Section 15.2 of this Agreement; and if Buyers
fail, within thirty (30) days following receipt of such notice from Seller, to
provide joint written instructions to the Escrow Agent to allow Seller to
withdraw such funds from the Buyer Deposit, then Seller may submit the dispute
to be resolved by dispute resolution set forth in Section 16.12. Buyer's
liability for indemnification under Section 15.2 of this Agreement shall not be
limited to the Buyer Deposit. Upon Closing, Seller agrees to seek recovery for
Seller's claims for indemnification under Section 15.2 of this Agreement against
the Buyer Deposit to the extent such claims do not exceed the Buyer Deposit. To

                               EFFECT OF CLOSING

          Section 12.1 Property Tax Proration. All ad valorem Taxes and real or
personal property Taxes attributable to the ownership of the Assets
(collectively "Property Taxes") with respect to the tax period in which the
Closing occurs (the "Current Tax Period") shall be apportioned between Seller
and Refinery Buyer as of the Closing with Seller being obligated to pay a
proportionate share of the actual amount of such Taxes for the Current Tax
Period determined by multiplying such actual Taxes by a fraction, the numerator
of which is the number of days in the Current Tax Period prior to the Closing
and the denominator of which is the total number of days in the Current Tax
Period; provided, however, that Seller's share of Property Taxes for the Current
Tax Period shall not include, and Seller shall not be obligated to pay or bear,
any interest, fine or penalty resulting from Refinery Buyer's failure to timely
and properly pay the Property Taxes for the Current Tax Period. An estimate of
Seller's share of such actual

                                      -55-

<PAGE>

Taxes for the Current Tax Period shall be based on the portion of the Purchase
Price allocated, pursuant to Section 3.6, to the real or personal property to
which such Taxes are attributable (but in no event less than the taxable value
most recently assessed by the applicable taxing units), and the Purchase Price
paid at Closing shall be reduced by the amount of such estimated Taxes owed by
Seller for that portion of the Current Tax Period prior to the Closing as
described in Section 3.3(a). When the actual amount of any such Taxes for the
Current Tax Period is known, Refinery Buyer shall promptly advise Seller of the
proportionate share of such actual Taxes for which Seller is obligated and
furnish Seller reasonably supporting documents evidencing the actual amount of
such Taxes. If the estimate of Seller's share of such actual Taxes made pursuant
to this subsection was less than Seller's share of such actual Taxes, Seller
shall pay Refinery Buyer such deficiency within ten (10) days of receipt of such
notice and reasonably supporting documents, and if such estimate was more than
Seller's share of such actual Taxes, Refinery Buyer will refund such excess to
Seller at the time such notice is given. Seller and Refinery Buyer agree that
any protest or contest of or affecting the taxable value of any of the Assets
for the 2005 tax year will be prosecuted, if at all, by Refinery Buyer, and
Seller is deemed to have assigned to Refinery Buyer at Closing (by execution of
the Deed) all such rights of protest or contest; provided, however, that
Refinery Buyer shall keep Seller informed of all developments and events
relating to any such protest or contest (including providing to Seller copies of
all written materials pertaining to any such protest or contest) and Seller or
its authorized representatives shall, at Seller's expense, be entitled to attend
and participate in any and all conferences, meetings and proceedings relating to
any such protest or contest; and, provided further, that in the event that any
such protest or contest results in a refund of Property Taxes, then any refund
shall be apportioned between Refinery Buyer and Seller on the basis of the
fraction described in the first sentence of this Section 12.1 applied to the net
sum recovered after Refinery Buyer's recovery of the out-of-pocket costs and
expenses (including third party consulting or legal fees whether hourly or
contingent) incurred by Refinery Buyer in prosecuting such protest or contest.
From and after the Closing,

          (i) Seller shall be obligated for, and shall indemnify Refinery Buyer
     and its Affiliates from and against, all Property Taxes relating to the
     ownership of the Assets which are attributable to the period prior to the
     Closing (except as provided in clause (ii)(3) below) and all Covered
     Liabilities with respect to such Taxes, and

          (ii) Refinery Buyer shall be obligated for, and shall indemnify Seller
     and its Affiliates from and against, (1) all Property Taxes relating to the
     ownership of the Assets which are attributable to the period after the
     Closing and all Covered Liabilities with respect to such Taxes, (2) all
     Property Taxes for the Current Tax Period and all Covered Liabilities with
     respect to such Taxes, and (3) all increases, reinstatements, reversals of
     abatements and other charges of Property Taxes relating to the ownership of
     the Assets which are attributable to the period prior to the Closing to the
     extent such increases, reinstatements, reversals of abatements and other
     charges are attributable to Refinery Buyer's or any of its successor's or
     assign's use, business, operations or activities with respect to the Assets
     after the Closing or the failure by Refinery Buyer or its successors or
     assigns to comply with any Tax abatement, reduction or similar agreement in
     effect prior to the Closing which has been disclosed in writing to Refinery
     Buyer.

          (a) Shared Accounts Receivable. All accounts or rentals receivable of
Seller for goods sold and delivered (or shipped or loaded for shipment), for
land, personalty or other property leased, or for services rendered prior to the
Closing Date in connection with Seller's Business or Assets are "Excluded
Assets" and are retained by Seller. If, however, the accrual period with respect
to any account or rental receivable for the lease of land, personalty or other
property included in the Assets or for services rendered as a direct part of
Seller's Business begins before and ends after the Closing Date, such account or
rental receivable (a "Shared Receivable") shall be apportioned between Seller
and Refinery Buyer in accordance with GAAP, to the extent applicable, and
otherwise in a fair and equitable manner based on the number of days in such
period before and after the Closing Date and the relative values of the land,
personalty or other property leased or the services rendered during such period
before and after the Closing Date, with Seller being entitled to the portion of
such Shared Receivable which is attributable to the period prior to the Closing
Date and with Refinery Buyer being entitled to the portion of such Shared
Receivable which is attributable to the period after the Closing Date.

          (b) Shared Accounts Payable. All accounts or rentals payable by Seller
for goods sold and delivered to Seller, for land, personalty or other property
leased, or for services rendered prior to the Closing Date in connection with
Seller's Business or the Assets shall be retained by Seller. If, however, the
accrual period with respect to any account or rental payable for the lease of
land, personalty or other property included in the Assets or for services
rendered as a direct part of Seller's Business begins before and ends after the
Closing Date, such account or rental payable (a "Shared Payable") shall be
apportioned between Seller and Refinery Buyer in accordance with GAAP, to the
extent applicable, and otherwise in a fair and equitable manner based on the
number of days in such period before and after the Closing Date and the relative
values of the land, personalty or other property leased or the services rendered
during such period before and after the Closing Date, with Seller being
obligated to pay the portion of such Shared Payable which is attributable to the
period prior to the Closing Date and with Refinery Buyer being obligated to pay
the portion of such Shared Payable which is attributable to the period after the
Closing Date.

          (c) Entitlements and Obligations. If any proceeds, revenues or monies
attributable to a Shared Receivable are received by any Party which, under the
terms of this Agreement, belong in whole or in part to the other Party, the
portion of such proceeds, revenues or monies to which the other Party is
entitled shall as soon as practicable, but not later than ten (10) Business Days
after receipt thereof, be paid over to the proper Party. If a Party receives an
invoice or other evidence of a Shared Payable which under the terms of Section
12.2(b) is in whole or in part the obligation of the other Party, then the
receiving Party shall as soon as practicable, but not later than ten (10)
Business Days after receipt thereof, forward to the responsible Party the
original or a copy of such invoice or obligation.

          (a) Each representation, warranty, covenant and agreement made herein
shall terminate and cease to be of further force and effect as of the Closing or
such later date after Closing as is expressly stipulated in this Section for the
survival thereof; provided, however, that any such representation, warranty,
covenant or agreement shall survive beyond the applicable date specified herein
with respect to any claim for indemnification under Article 15 based on such
representation, warranty, covenant or agreement provided that a Claim Notice
with respect to such claim has been delivered to the applicable Indemnitor on or
prior to such date. Neither the officer's certificates of Buyers referred to in
Section 10.1(b) or 11.3(b) nor the officer's certificate of Seller referred to
in Section 10.2(b) or Section 11.2(b) shall operate or cause any underlying
representation, warranty, covenant or agreement referenced or certified to
therein, or any Buyer's or Seller's obligations under said certificate with
respect to such representation, warranty, covenant or agreement, to change or
survive later than the time stipulated for the survival of such representation,
warranty, covenant or agreement in this Section. Following the Closing or such
later date stipulated in this Section for the survival thereof, no
representation, warranty, covenant or agreement shall form the basis for or give
rise to any claim, demand, cause of action, counterclaim, defense, damage,
indemnity, obligation or liability which is asserted, claimed, made or filed by
a Party to this Agreement (or its successors or assigns as permitted herein). It
is expressly agreed that the terms and provisions of:

     below) and Sections 3.3, 3.4, 3.5, 7.1, 9.1, 9.3(a)(i) and 9.11 shall

     and 16, shall survive the Closing without limitation or for such shorter
     period of time as may be stipulated in such provisions or allowed by Law,
     and

          (iv) Sections 4.1(n), 4.1(p) and 4.l(u) shall not survive the
     Closing.

     Agreement or in any other provision of this Agreement which are used in the
     representations, warranties, covenants and agreements which survive the
     Closing pursuant to this Section shall survive the Closing to the extent

          (a) Termination of Agreement. This Agreement and the transactions
contemplated hereby may be terminated at any time prior to the Closing:

          (1) By the mutual consent of Seller and Buyers; or

          (2) If the Closing has not occurred by the close of business on June
     15, 2005, then (i) by Seller if any condition specified in Section 10.1 has
     not been satisfied on or before such close of business, and shall not
     theretofore have been waived by Seller, or (ii) by Buyers if any condition
     specified in Section 10.2 (other than the conditions specified in Sections
     10.2(n) and 10.2(o)) has not been satisfied on or before such close of
     business, and shall not theretofore have been

                                      -61-

<PAGE>

     waived by Buyers; provided, in each case, that the failure to consummate
     the transactions contemplated hereby on or before such date did not result
     from any breach of this Agreement by the Party or Parties seeking
     termination of this Agreement;

          (3) By Buyers, if a material breach (or a breach, in the case of
     covenants which are qualified by the requirement of a Material Adverse
     Effect or otherwise by the term "material" or its derivatives) shall have
     occurred in the observance or performance by Seller of any agreements and
     covenants of Seller contained herein, or if there shall have been a
     material breach (or a breach, in the case of representations and warranties
     which are qualified by the requirement of a Material Adverse Effect or
     otherwise by the term "material" or its derivatives) of any of Seller's
     representations or warranties contained herein and, in each case, such
     default or breach either (A) is not cured within 30 days after receipt by
     Seller of written notice from Buyers of such default or breach or (B) is
     incapable of being cured;

          (4) By Seller, if a material breach (or a breach, in the case of
     covenants which are qualified by the requirement of a Material Adverse
     Effect or otherwise by the term "material" or its derivatives) shall have
     occurred in the observance or performance by Buyers of any agreements and
     covenants of Buyers contained herein, or if there shall have been a
     material breach (or a breach, in the case of representations and warranties
     which are qualified by the requirement of a Material Adverse Effect or
     otherwise by the term "material" or its derivatives) of any of Buyers'
     representations or warranties contained herein and, in each case, such
     default or breach either (A) is not cured within 30 days after receipt by
     Buyers of written notice from Seller of such default or breach or (B) is
     incapable of being cured; or

          (5) By either Party, if there shall be any order, writ, injunction or
     decree of any Governmental Authority binding Seller or any Buyer which
     prohibits or restrains Seller or any Buyer from consummating the
     transactions contemplated hereby and such order, writ, injunction or decree
     shall have become final.

          (b) Effect of Termination. Without limiting Seller's and Buyers'
respective remedies and rights in regard to the Earnest Money Deposit under
Section 14.2, in the event of termination of this Agreement by Seller, on the
one hand, or Buyers, on the other hand, pursuant to Section 14.1 (a), written
notice thereof shall forthwith be given by the terminating Party to the other
Party hereto, and this Agreement shall thereupon terminate; provided, however,
that following such termination Buyers will continue to be bound by its
obligations set forth in Sections 5.1, 5.3 and 6.1(c). If this Agreement is
terminated as provided herein all filings, applications and other submissions
made to any Governmental Authority shall, to the extent practicable, be
withdrawn from the Governmental Authority to which they were made.

          Section 14.2 Remedies.

          (a) Seller's Remedies. If this Agreement is not terminated pursuant to
Section 14.1(a)(l) or 14.1(a)(5) or by Buyers pursuant to Section 14.l(a)(2) or
14.1(a)(3) and Buyers fail to satisfy on or prior to the Closing Date the
conditions to Closing or the Closing obligations, as the case may be, set forth
in Sections 10.1(a), 10.1(b), 10.1(c), 10.1(f) or 11.3, Seller may terminate
this Agreement, without waiving or releasing Buyers' obligations under Sections
5.1, 5.3 and 6.1(c). If Seller terminates this Agreement pursuant to Section
14.1(a)(4) or the immediately preceding sentence, then Seller shall immediately
become entitled to collect and receive the Earnest Money Deposit from the Escrow
Agent, together with all interest and other amounts earned thereon. Seller and
Buyers have agreed upon the Earnest Money Deposit amount, together with all
interest and other amounts, if any, earned thereon, as liquidated damages due to
the difficulty and inconvenience of measuring actual damages and the uncertainty
thereof, and Seller and Buyers agree that such amount is a reasonable estimate
of Seller's loss in the event of any such failure or breach by Buyers.
Notwithstanding anything to the contrary contained in this Agreement, the
foregoing remedies shall be Seller's sole and exclusive remedies for such
failure or breach, all other remedies being expressly waived by Seller.

          (b) Buyer's Remedies. If this Agreement is not terminated pursuant to
Section 14.1(a)(l) or 14.1(a)(5) or by Seller pursuant to Section 14.1(a)(2) or
14.1(a)(4) and Seller fails to satisfy on or prior to the Closing Date the
conditions to Closing or the Closing obligations, as the case may be, set forth
in Sections 10.2(a), lO.2(b), 10.2(c) or 11.2, Buyers, at their sole option, may
(i) enforce specific performance of this Agreement or (ii) terminate this
Agreement. Without limiting the generality of the foregoing, Seller and Buyers
agree that Buyers shall be entitled to seek injunctive relief in the event of a
breach by Seller of its obligations set forth in the proviso contained in
Section 5.4. If Buyers terminate this Agreement pursuant to Section 14.1(a)(3)
or the immediately preceding sentence, then Buyers shall immediately become
entitled (i) to collect and receive the Earnest Money Deposit from the Escrow
Agent, together with any interest and other amounts earned thereon, and (ii) to
payment by Seller in the amount of $1,200,000.00 as liquidated damages on
account of such failure by Seller. Seller and Buyers have agreed upon the amount
of $1,200,000.00 as liquidated damages due to the difficulty and inconvenience
of measuring actual damages and the uncertainty thereof, and Seller and Buyers
agree that such amount is a reasonable estimate of Buyers' loss in the event of
any such failure or breach by Seller. Notwithstanding anything to the contrary
contained in this Agreement, the foregoing remedies shall be Buyers' sole and
exclusive remedies for such failure or breach, all other remedies being
expressly waived by Buyers.

          Section 15.1 Indemnification by Seller.

          (a) From and after the Closing, Seller shall indemnify, hold harmless

                                      -63-

the directors, officers, heirs, executors, successors and assigns of any of the
foregoing (collectively, the "Buyer Indemnitees") from and against (i) the
Retained Environmental Liabilities, (ii) the Pre-Closing Liabilities, (iii) all
Covered Liabilities resulting from any breach or non-fulfillment of any
representation, warranty, covenant or agreement (without giving effect to any
materiality or Material Adverse Effect qualification in such representation,
warranty, covenant or agreement) on the part of Seller which is expressly set
forth in this Agreement, and (iv) all Covered Liabilities arising under or in
connection with any Excluded Assets.

          (b) From and after the Closing Date, Seller shall be responsible for,
and shall indemnify, hold harmless and defend each of Buyer Indemnitees against:

          (1)  all Taxes (other than Section 338 Taxes) imposed on Land Newco or
               Pipeline Newco, and all Covered Liabilities arising therefrom,
               relating to:

               (a)  taxable periods and, in the case of franchise Taxes,
                    Privilege Periods ending on or before the Closing Date;

               (b)  any Taxes for which Land Newco or Pipeline Newco is or may
                    be severally liable under Treas. Reg. 1.1502-6 or any
                    analogous state, local or foreign Law by reason of its
                    having been a member of any consolidated, combined, or
                    unitary group on or prior to the Closing Date; and

               (c)  in the case of any Taxes of Land Newco or Pipeline Newco
                    relating to a Straddle Period or a Privilege Period
                    beginning on or before the Closing Date and ending after the
                    Closing Date, the portion of such Taxes for which the Seller
                    is responsible under Section 9.9(b); and

          (2)  all Taxes that are imposed on or asserted against Refinery Buyer
               as successor or transferee of Seller with respect to the Assets
               pursuant to Texas Tax Code Section 111.020, Texas Labor Code
               Section 204.086, or any similar provisions; and

          (3)  all property Taxes for which the Seller is responsible under

          (c) Seller's indemnification obligation under this Section 15.1 shall
expressly include indemnification of the Buyer Indemnitees against ANY LIABILITY
BASED IN WHOLE OR IN PART ON NEGLIGENCE, NEGLIGENCE PER SE, GROSS NEGLIGENCE OR
STRICT LIABILITY OF THE BUYER INDEMNITEE OR ON ANY OTHER THEORY OF LIABILITY,
WHETHER IN LAW (WHETHER COMMON, CIVIL OR STATUTORY) OR EQUITY. The obligations
of Seller in this Article 15 are subject to the limitations in Article 13 and
Section 15.4.

                                      -64-

<PAGE>

          (a) From and after the Closing, Buyers, jointly and severally, shall
assume, pay, perform, fulfill, and discharge all Assumed Liabilities and shall
indemnify, hold harmless and defend Seller, Seller's respective Affiliates, each
of their respective directors, officers, employees, consultants and agents, and
each of the directors, officers, heirs, executors, successors and assigns of any
of the foregoing (collectively, the "Seller Indemnitees") from and against (i)
the Assumed Liabilities, (ii) all Covered Liabilities resulting from any breach
or nonfulfillment of any representation, warranty, covenant or agreement
(without giving effect to any materiality or Material Adverse Effect
qualification in such representation, warranty, covenant or agreement) on the
part of any Buyer which is expressly set forth in this Agreement, and (iii) all
Covered Liabilities resulting from any obligations under any Existing Credit
Support which is not released by the applicable beneficiary.

          (b) From and after the Closing Date, Buyers shall be responsible for,
and, jointly and severally, shall indemnify, hold harmless and defend each of
Seller Indemnitees against:

          (1)  all Taxes imposed on Land Newco or Pipeline Newco, and all
               Covered Liabilities resulting therefrom, relating to:

               (a)  taxable periods and, in the case of franchise Taxes,
                    Privilege Periods, beginning after the Closing Date;

               (b)  all Section 338 Taxes; and

               (c)  in the case of any Taxes of Land Newco or Pipeline Newco
                    relating to a Straddle Period or a Privilege Period
                    beginning on or before the Closing Date and ending after the
                    Closing Date, the portion of such Taxes for which the
                    Buyers, Land Newco or Pipeline Newco are responsible under
                    Section 9.9(b); and

          (2)  all Transfer Taxes, federal excise Taxes, and property Taxes for
               which the Buyers, Land Newco or Pipeline Newco are responsible
               under Section 9.9(a) and Section 12.1.

          (c) Buyers' indemnification obligations under this Section 15.2 shall
expressly include indemnification of the Seller Indemnitees against ANY
LIABILITY BASED IN WHOLE OR IN PART ON NEGLIGENCE, NEGLIGENCE PER SE, GROSS
NEGLIGENCE OR STRICT LIABILITY OF THE SELLER INDEMNITEE OR ON ANY OTHER THEORY
OF LIABILITY, WHETHER IN LAW (WHETHER COMMON, CIVIL OR STATUTORY) OR EQUITY. The
obligations of Buyers in this Article 15 are subject to the limitations in
Article 13 and Section 15.4.

          Section 15.3 Indemnification and Defense Procedures. A Person which is
entitled to be indemnified under Section 15.1 or 15.2 is herein referred to as
an "Indemnitee" and the Party which is obligated to indemnify an Indemnitee
under Section 15.1 or 15.2 is herein

                                      -65-

<PAGE>

referred to as the "Indemnitor" with respect to the matter for which it is
obligated to indemnify such Indemnitee. All claims for indemnification under
Sections 15.1 and 15.2 shall be asserted and resolved as follows:

          (a) If a Third Party Claim for which an Indemnitee is entitled to
indemnity under Sections 15.1 and/or 15.2 (an "Indemnified Claim") is made
against an Indemnitee, and if Seller or Buyers intend to seek indemnity with
respect thereto by or from an Indemnitor pursuant to Sections 15.1 and/or 15.2,
then the Party electing to seek indemnity on behalf of such Indemnitee shall
promptly transmit to the Indemnitor a written notice ("Claim Notice") (i)
notifying such Indemnitor of such Indemnified Claim and request indemnity on
behalf of such Indemnitee with respect to such Indemnified Claim under Sections
15.1 and/or 15.2, as the case may be, (ii) setting forth the full name, address
for all notices and the authorized Representatives of such Indemnitee with
respect to such Indemnified Claim, and (iii) describing in reasonable detail the
nature of the Indemnified Claim, including a copy of all papers served with
respect to such Indemnified Claim (if any) and the basis of such request for
indemnification under Sections 15.1 and/or 15.2, as the case may be. Failure to
provide such Claim Notice promptly shall not affect the right of the Indemnitee
to indemnification hereunder except to the extent the Indemnitor is prejudiced
thereby; provided that, the Indemnitor shall not be obligated to defend,
indemnify or otherwise hold harmless an Indemnitee with respect to a Third Party
Claim until a Claim Notice meeting the foregoing requirements is furnished to
the Indemnitor by the Party seeking indemnity hereunder and any Covered
Liability resulting from such delay in defense, indemnification or holding
harmless of such Indemnitee shall not be covered by the Indemnitor's
indemnification obligations with respect to such Indemnified Claim or such
Indemnitee. Within 30 days after receipt of any Claim Notice (the "Election
Period"), the Indemnitor shall notify the Party who sent the Claim Notice (A)
whether the Indemnitor disputes its potential liability to indemnify the
Indemnitee under Sections 15.1 and/or 15.2, as the case may be, with respect to
such Third Party Claim and (B) whether the Indemnitor desires to defend the
Indemnitee against such Third Party Claim; provided that, if the Indemnitor
fails to so notify the Indemnitee during the Election Period, the Indemnitor
shall be deemed to have elected to dispute such liability and not to defend
against such Third Party Claim. The aforesaid election or deemed election by the
Indemnitor not to assume the defense of the Indemnitee with respect to such
Indemnified Claim, however, shall be subject to the right of the Indemnitor to
subsequently assume the defense of the Indemnitee with respect to such
Indemnified Claim at any time prior to settlement or final determination
thereof.

          (b) If the Indemnitor notifies the Party who sent the Claim Notice
within the Election Period that the Indemnitor (i) does not dispute its
liability to indemnify the Indemnitee under Sections 15.1 and/or 15.2, as the
case may be (or reserves the right to dispute whether such claim is an
Indemnified Claim under Sections 15.1 and/or 15.2) and (ii) elects to assume the
defense of such Indemnitee with respect to such Third Party Claim, then the
Indemnitor shall have the right to defend, at its sole cost and expense, and
using counsel reasonably acceptable to the Indemnitee, such Third Party Claim by
all appropriate proceedings, which proceedings shall be prosecuted diligently by
the Indemnitor to a final conclusion or settled at the discretion of the
Indemnitor in accordance with this Section 15.3(b). If an Indemnitor elects
pursuant to the foregoing to assume the defense of an Indemnitee with respect to
a Third Party Claim which is

                                      -66-

<PAGE>

subsequently determined not to be an Indemnified Claim, then, without limiting
any action the Indemnitor may have on account of actual fraud, the Indemnitor
shall not be entitled to recover from the other Party or the Indemnitee the
costs and expenses incurred by the Indemnitor in providing such defense. The
Indemnitor shall have full control of such defense and proceedings, including
any compromise or settlement thereof; provided, however, the Indemnitor shall
not enter into any settlement agreement (or settle or compromise any such Third
Party Claim in a manner) which provides for or results in any payment by or
liability of the Indemnitee of or for any damages or other amount, any Lien on
any property of the Indemnitee, any finding of responsibility or liability on
the part of the Indemnitee or any sanction or restriction upon the conduct of
any business by the Indemnitee or any obligation or action on the part of the
Indemnitee without the Indemnitee's express written consent, which consent shall
not be unreasonably withheld.

          (c) The Indemnitee is hereby authorized, at the sole cost and expense
of the Indemnitor (but only if the Indemnitee is actually entitled to
indemnification hereunder), to file, during the Election Period, any motion,
answer or other pleadings which the Indemnitee shall deem necessary or
appropriate to protect its interests or those of the Indemnitor and not
reasonably expected to be prejudicial to the Indemnitor. If requested by the
Indemnitor, the Indemnitee agrees, at the sole cost and expense of the
Indemnitor, to cooperate with the Indemnitor and its counsel in contesting any
such Third Party Claim which the Indemnitor elects to contest, including the
making of any related counterclaim or cross-complaint against any Person (other
than a Seller Indemnitee, if the Indemnitee is a Seller Indemnitee, or a Buyer
Indemnitee, if the Indemnitee is a Buyer Indemnitee). The Indemnitee may
participate in, but not control, any defense or settlement of any Third Party
Claim controlled by the Indemnitor pursuant to this Section 15.3(c), and the
Indemnitee shall bear its own costs and expenses with respect to such
participation. The prosecution of the defense of a Third Party Claim with
reasonable diligence shall include the taking of such action (including the
posting of a bond, deposit or other security) as may be necessary to prevent any
action to foreclose a Lien against or attachment of the property of the
Indemnitee for payment of such Third Party Claim.

          (d) If the Indemnitor (i) fails to notify the Party who sent the Claim
Notice within the Election Period that the Indemnitor elects to defend the
Indemnitee pursuant to Section 15.3(b) or (ii) elects to defend the Indemnitee
pursuant to Section 15.3(b) but fails to prosecute the defense of the Third
Party Claim with reasonable diligence, then the Indemnitee shall have the right
to defend, at the sole cost and expense of the Indemnitor (but only if the
Indemnitee is actually entitled to indemnification hereunder), the Third Party
Claim by all appropriate proceedings, which proceedings shall be promptly and
vigorously prosecuted by the Indemnitee to a final conclusion or settled. Unless
and until such defense is assumed by the Indemnitor as permitted in Section
15.3(a), the Indemnitee shall have full control of such defense and proceedings;
provided, however, that the Indemnitor, without assuming the defense of such
Indemnified Claim, may participate in, but not control, any defense or
settlement controlled by the Indemnitee pursuant to this Section 15.3(d), and
the Indemnitor shall bear its own costs and expenses with respect to such
participation. The Indemnitee may not enter into any compromise or settlement of
such Third Party Claim, without the Indemnitor's express written consent, which
shall not be unreasonably withheld.

                                      -67-

          (e) If an Indemnitee is entitled to indemnity under Sections 15.1
and/or 15.2 for a claim or other matter which does not involve a Third Party
Claim, and if Seller or Buyer intends to seek indemnity on behalf of an
Indemnitee with respect thereto by or from an Indemnitor pursuant to Sections
15.1 and/or 15.2, then the Party electing to seek indemnity on behalf of an
Indemnitee shall promptly transmit to the Indemnitor a written notice describing
in reasonable detail the nature of such claim or other matter, the Indemnitee's
best estimate of the amount of damages attributable to such claim or other
matter and the basis for the Indemnitee's entitlement to indemnification under
Sections 15.1 and/or 15.2, as the case may be. If the Indemnitor does not notify
the Party who sent such notice within 30 days from its receipt of such notice
that the Indemnitor does not dispute such claim for indemnity, the Indemnitor
shall be deemed to have disputed such claim.

          (f) To the extent any claim, action, suit or proceeding includes one
or more Indemnified Claims with respect to an Indemnitee and one or more Third
Party Claims which are not Indemnified Claims with respect to such Indemnitee,
any such non-Indemnified Claim insofar as it is with respect to such Indemnitee
shall not be covered by the indemnity in Sections 15.1 and 15.2, the Indemnitor
shall not be obligated to undertake, conduct and control the defense or
settlement of such non-Indemnified Claim insofar as it is with respect to such
Indemnitee, and such Indemnitee shall be responsible for its own defense and
settlement of such non-Indemnified Claim. The seeking by a Party of indemnity
hereunder on behalf of any Indemnitee with respect to any Third Party Claim or
other claim or matter shall not prevent such Party from then or thereafter also
seeking indemnity hereunder on behalf of any other Indemnitee with respect to
such Third Party Claim or other claim or matter and shall not prevent the other
Party from seeking indemnity hereunder on behalf of any Indemnitee with respect
to the same Third Party Claim or other claim or matter.

          Section 15.4 Liability Limitations.

          (a) Notwithstanding anything herein provided to the contrary, but
subject to the last sentence of this subsection and to the further provisions of
this Section 15.4 and Article 13,

          (1) Seller shall have no liability to Buyers or any other Buyer
     Indemnitee pursuant to clause (iii) of Section 15.1(a) unless and until the
     aggregate amount of all Covered Liabilities covered by clause (iii) of
     Section 15.1(a) exceeds $250,000.00 (the "Deductible Amount"), and then
     Seller shall only be liable for the portion of such aggregate amount of all
     Covered Liabilities covered by clause (iii) of Section 15.1(a) that exceeds
     the Deductible Amount; and

          (2) without limiting the foregoing deductible basket, Seller shall
     have no liability to Buyers or any other Buyer Indemnitee pursuant to
     clause (iii) of Section 15.1(a) for any claim under clause (iii) of Section
     15.1(a) unless the net present value (using a discount rate equal to the
     Agreed Rate) of such claim exceeds $25,000.00; provided, however, a series
     of related claims arising out of

                                      -68-

<PAGE>

     substantially the same facts and circumstances shall be considered the same
     claim for purposes of meeting the foregoing threshold amount.

The foregoing provisions of this subsection (a) shall not apply to any breach or
non-fulfillment of any covenant or agreement, or any amounts payable under or
pursuant to,

          (i)  Article 3, 7, 8, 9, 11,13, 15 (other than Section 15.1(b)), or
               16,

          (ii) Sections 5.3, 12.1 or 12.2,

          (iii) Seller's obligation to pay Retained Environmental Liabilities
               pursuant to Section 15.1, or

          (iv) Seller's obligation to pay Pre-Closing Liabilities pursuant to
               Section 15.1.

          (b) Notwithstanding anything herein provided to the contrary, but
subject to the last sentence of this subsection and to the further provisions of
this Section 15.4 and Article 13,

          (1) Buyers shall have no liability to Seller or any other Seller
     Indemnitee pursuant to clause (ii) of Section 15.2(a) unless and until the
     aggregate amount of all Covered Liabilities covered by clause (ii) of
     Section 15.2(a) exceeds the Deductible Amount, and then Buyers shall only
     be liable for the portion of such aggregate amount of all Covered
     Liabilities covered by clause (ii) of Section I5.2(a) that exceeds the
     Deductible Amount; and

          (2) without limiting the foregoing deductible basket, Buyers shall
     have no liability to Seller or any other Seller Indemnitee pursuant to
     clause (ii) of Section 15.2(a) for any claim under clause (ii) of Section
     15.2(a) unless the net present value (using a discount rate equal to the
     Agreed Rate) of such claim exceeds $25,000.00; provided, however, a series
     of related claims arising out of substantially the same facts and
     circumstances shall be considered the same claim for purposes of meeting
     the foregoing threshold amount.

The foregoing provisions of this subsection (b) shall not apply to any breach or
non-fulfillment of any covenant or agreement, or any amounts payable under or
pursuant to,

          (i)  Article 3, 7, 8, 9, 11, 13, 15 (other than Section 15.2(b)), or
               16,

          (ii) Section 5.1, 5.3, 6.1(c), 12.1 or 12.2, or

          (iii) Buyers' assumption of and obligation to pay Assumed Liabilities
               pursuant to Section 15.2.

          (c) Seller, Buyers, and each other Indemnitee shall cooperate with the
Indemnitor with respect to resolving any Indemnified Claim with respect to which
either Seller

                                      -69-

<PAGE>

or Buyers are obligated to indemnify an Indemnitee under this Article 15,
including making commercially reasonable efforts to mitigate or resolve any such
Indemnified Claim and providing the others with reasonable access to such
Indemnitee's records (other than those subject to attorney-client or attorney
work product privilege) and personnel having relevant information with respect
to the Indemnified Claim. Without limiting the foregoing, to the extent it may
legally do so each Party agrees to assign or cause the assignment and/or
subrogation to the Indemnitor with respect to an Indemnified Claim any and all
of the rights and remedies that the Indemnitee may have with respect to such
Indemnified Claim against any Person (other than Seller, Buyers, or any
Affiliate of Seller or Buyers or any insurance carrier or bonding or surety
company of the Indemnitee) pursuant to any claims, rights and agreements of or
for indemnification, guarantee, contribution, reimbursement or similar
assurances which are the subject of such Indemnified Claim. The amount of an
Indemnified Claim shall be reduced by the amount, if any, of insurance proceeds
and other third party payments realized or recovered by the Indemnitee with
respect to such Indemnified Claim (net of reasonable collection costs). The
indemnifications provided under this Article 15 shall not be construed as a form
of insurance.

          (d) Each Party agrees to maintain all records and information made
available to it pursuant to Section 15.4(c) confidential and to cause its
Representatives, consultants and advisors to maintain all records and
information made available to them pursuant to this Article 15 confidential,
except (i) as required by Law, administrative process or any standards or rules
of any stock exchange to which such Party or any of its Affiliates is subject,
(ii) for information which is available to the public on the date hereof, or
thereafter becomes available to the public other than as a result of a breach of
this Section 15.4(d), and (iii) to the extent that such Party must disclose the
same in any court or arbitration proceedings brought by it to enforce its rights
hereunder.

          (e) Without limiting or affecting either Party's obligations under
this Article 15 to defend an Indemnitee against a claim or to conduct, perform
or pay for Remediation or other Environmental Activities or increasing or
expanding either Party's obligations under this Article 15, neither Party shall
be obligated to indemnify or hold harmless any Indemnitee with respect to a
contingent, unmatured, unaccrued or unliquidated Covered Liability unless and
until such time as such Covered Liability is or becomes realized, matured,
accrued and liquidated.

          Section 15.5 Exclusive Remedy. After Closing, the indemnity provisions
of this Article 15 shall be the sole and exclusive remedy of each Party for or
on account of any breach by the other Party of any of such other Party's
representations and warranties under this Agreement. THE PARTIES ACKNOWLEDGE AND
AGREE THAT THE REMEDIES SET FORTH IN THIS AGREEMENT OR THE RELATED AGREEMENTS,
INCLUDING THE DEDUCTIBLES, LIABILITY LIMITS, SURVIVAL PERIODS, DISCLAIMERS AND
LIMITATIONS ON REMEDIES, ARE INTENDED TO BE, AND SHALL BE, THE EXCLUSIVE
REMEDIES WITH RESPECT TO ANY ASPECT OF THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT OR THE RELATED AGREEMENTS. EACH PARTY HEREBY RELEASES, WAIVES AND
DISCHARGES, AND COVENANTS NOT TO SUE WITH RESPECT TO, ANY CAUSE OF ACTION OR
CLAIM NOT EXPRESSLY PROVIDED FOR IN THIS AGREEMENT

LAWS, AVAILABLE AT COMMON LAW OR BY STATUTE (INCLUDING ANY CLAIM UNDER OR

CODE).

                                 MISCELLANEOUS

          Section 16.1 Counterparts. This Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same agreement,

          Section 16.2 Governing Law; Jurisdiction.

          (a) THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY SHALL BE
GOVERNED BY AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS
WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW RULES
THAT WOULD DIRECT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION, EXCEPT TO
THE EXTENT THAT IT IS MANDATORY THAT THE LAW OF ANOTHER JURISDICTION, WHEREIN
THE ASSETS ARE LOCATED, SHALL APPLY.

          (b) SUBJECT TO THE ARBITRATION AGREEMENT SET FORTH IN SECTION 16.12,
BUYERS AND SELLER CONSENT TO PERSONAL AND SUBJECT MATTER JURISDICTION OF ANY
FEDERAL OR STATE COURT LOCATED IN HARRIS COUNTY, TEXAS IN ANY LEGAL ACTION, SUIT

          Section 16.3 Entire Agreement. This Agreement (including the
Confidentiality Agreement) and the Appendices, Schedules and Exhibits hereto
contain the entire agreement between the Parties with respect to the subject
matter hereof and supersede all other agreements, arrangements, negotiations and

agreements, understandings, representations or warranties between the Parties
other than those set forth or referred to herein.

          Section 16.4 Expenses. Buyers shall be responsible for all recording,
filing or registration fees relating to the filing, recording or registration of
the Deed, the Conveyance and any other instruments or documents transferring
title in or to the Assets or any part thereof from Seller to Refinery Buyer

this Agreement is terminated by Seller or Buyers pursuant to Section 14.1(a)(2)
or Section 14.1(a)(5), or by Buyers pursuant to Section 14.1(a)(3), then Seller

          Section 16.6 Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the Parties and their respective successors and
assigns; provided, however, that the respective rights and obligations of the
Parties shall not be assignable or delegable by any Party without the express
written consent of the non-assigning or non-delegating Party. Each Party,
however, shall have the right to assign this Agreement or any part hereof to any
direct or indirect wholly-owned Affiliate of such Party without obtaining the
other Party's consent in a transaction which is not entered into or made in
contemplation of directly or indirectly transferring ownership or control of
such Affiliate. All assignments permitted or consented to hereunder (i) shall
be, and by their terms shall expressly provide that they are, subject to the
rights of the other Party under this Agreement, (ii) shall require that the
assignee agree to be bound by and perform all obligations of the assigning Party
hereunder with respect to the interest so assigned, and (iii) shall not release
the assigning Party or its predecessor Parties in interest under this Agreement
from their obligations under this Agreement. Any purported assignment of this
Agreement in whole or in part without the written consent of the non-assigning
Party or Parties where required by the provisions of this Section shall be void.
The foregoing restrictions on assignment in this Section are not intended to
restrict, and shall have no effect on, Buyers' right to subsequently assign all
or any portion of the Assets or Land Newco Shares or Pipeline Newco Shares.

          Section 16.7 Amendments and Waivers. This Agreement may not be
modified or amended except by an instrument or instruments in writing signed by
the Party against whom enforcement of any such modification or amendment is
sought. Any Party may, only by an

                                      -74-

<PAGE>

instrument in writing, waive compliance by another Party with any term or
provision of this Agreement on the part of such other Party to be performed or
complied with. The waiver by any Party of a breach of any term or provision of
this Agreement shall not be construed as a waiver of any subsequent breach.

          Section 16.8 Agreement for the Parties' Benefit Only. This Agreement
is for the sole benefit of Buyers, Seller and their respective successors and
assigns as permitted herein and no other Person shall be entitled to enforce
this Agreement, rely on any representation, warranty, covenant or agreement
contained herein, receive any rights hereunder or be a third party beneficiary
of this Agreement. Any Indemnitee which is a third party shall be indemnified
and held harmless under the terms of this Agreement only to the extent that a
Party expressly elects to exercise such right of indemnity and hold harmless on
behalf of such third party Indemnitee pursuant to Section 15.3; and no Party
shall have any direct liability or obligation to any third party or be liable to
any third party for any election or non-election or any act or failure to act
under or in regard to any term of this Agreement. Any claim for indemnity or
hold harmless hereunder on behalf of an Indemnitee must be made and administered
by a Party to this Agreement.

          Section 16.9 Attorneys' Fees. The prevailing Party in any legal
proceeding or arbitration brought under or to enforce this Agreement shall be
additionally entitled to recover court costs and reasonable attorneys' fees
(including reasonable charges for the time of the prevailing Party's in-house
attorneys) from the non-prevailing Party.

          Section 16.10 Severability. If any term, provision or condition of
this Agreement, or any application thereof, is held invalid, illegal or
unenforceable in any respect under any Law, this Agreement shall be reformed to
the extent necessary to conform, in each case consistent with the intention of
the Parties, to such Law, and to the extent such term, provision or condition
cannot be so reformed, then such term, provision or condition (or such invalid,
illegal or unenforceable application thereof) shall be deemed deleted from (or
prohibited under) this Agreement, as the case may be, and the validity, legality
and enforceability of the remaining terms, provisions and conditions contained
herein (and any other application of such term, provision or condition) shall
not in any way be affected or impaired thereby. Upon such determination that any
term or other provision is invalid, illegal or incapable of being enforced, the
Parties shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the Parties as closely as possible in an acceptable
manner to the end that the transactions contemplated hereby are fulfilled to the
extent possible.

          Section 16.11 Time of Essence. Time is of the essence in this
Agreement. If the date specified in this Agreement for giving any notice or
taking any action is not a Business Day (or if the period during which any
notice is required to be given or any action taken expires on a date which is
not a Business Day), then the date for giving such notice or taking such action
(and the expiration date of such period during which notice is required to be
given or action taken) shall be the next day which is a Business Day.

          Section 16.12 Arbitration.

          (a) Except as provided in Sections 3.3, 3.5 and 9.9(b), this Section
16.12 shall govern resolution of any disputes arising under this Agreement. It
is agreed, as a severable and independent arbitration agreement separately
enforceable from the remainder of this Agreement, that if the Parties, the
Indemnitees or the respective successors, assigns, heirs or legal
representatives of any of the foregoing are unable, within thirty (30) days of
notice from one Party to the other that a dispute or difference exists, to
amicably resolve any dispute or difference arising under or out of, in relation
to or in any way connected with this Agreement (whether contractual, tortious,
equitable, statutory or otherwise), except for such matters governed by Section
3.3 as to the determination of the purchase price for the Inventory, Section 3.5
as to the determination of the Adjustment Amount and Section 9.9(b) as to the
determination of certain Taxes, such matter shall be finally and exclusively
referred to and settled or determined by arbitration under the then extant
Commercial Arbitration Rules of the American Arbitration Association ("AAA"). In
the event of any conflict between the Commercial Arbitration Rules of the AAA
and the provisions of this Section 16.12, the provisions of this Section 16.12
shall govern and control.

          (b) The arbitration shall be heard and determined by three (3)
arbitrators. Each side shall appoint an arbitrator of its choice within fifteen
(15) days of the submission of a notice of arbitration. The Party-appointed
arbitrators shall in turn appoint a presiding arbitrator of the tribunal within
fifteen (15) days following the appointment of both Party-appointed arbitrators.
If the Party-appointed arbitrators cannot reach agreement on a presiding
arbitrator of the tribunal and/or one Party fails or refuses to appoint its
Party-appointed arbitrator within the prescribed period, the appointing
authority for the presiding arbitrator and/or such Party-appointed arbitrator
shall be the AAA, who, in each case, shall appoint an independent arbitrator who
does not have any financial interest in the dispute, controversy or claim or
bear any relationship to either Party. The presiding arbitrator must be a
licensed and practicing attorney (including any attorney practicing in-house for
a company, with an outside law firm, as a solo practitioner, or as a
professional arbitrator) or a retired judge of a U.S. state or federal court. If
an arbitrator should die, withdraw or otherwise become incapable of serving, or
refuse to serve, a successor arbitrator shall be selected and appointed in the
same manner as the original arbitrator.

          (c) Unless otherwise expressly agreed in writing by the Parties:

          (i) The arbitration proceedings shall be held in Houston, Texas;

          (ii) The arbitrators shall be and remain at all times wholly
     independent and impartial;

          (iii) The arbitration proceedings shall be conducted under the then
     extant Commercial Arbitration Rules of the AAA;

          (iv) Any procedural issues not determined under the arbitration rules
     selected pursuant to Section 16.12(c)(iii) shall be determined by the
     arbitration act and any other

                                      -76-

<PAGE>

     Laws of the State of Texas, other than those Laws which would refer the
     matter to another jurisdiction;

          (v) All decisions and awards by the arbitration tribunal shall be made
     by majority vote;

          (vi) The decision of a majority of the arbitrators shall be reduced to
     writing; shall be final and binding without the right of appeal; and shall
     be the sole and exclusive remedy regarding any claims, counterclaims,
     issues or accountings or other matters presented to the arbitrators; any
     damage awards by the arbitrators shall be promptly paid by the owing Party
     free of any deduction or offset; and any costs or fees incident to
     enforcing the award shall to the maximum extent permitted by Law be charged
     against the Party unsuccessfully resisting such enforcement;

          (vii) Consequential, indirect, special, exemplary, punitive or other
     similar damages shall not be allowed except those payable to third parties
     (and permitted under Section 16.8) for which liability is allocated among
     the Parties by the arbitration award;

          (viii) Any award of damages shall include interest from the date of
     any breach or violation of this Agreement, as determined by the arbitration
     award, until paid in full, at the Agreed Rate in effect at the end of the
     first Business Day during which such amount was owed;

          (ix) The costs of the arbitration proceedings (including attorneys'
     fees and costs) shall be borne in the manner determined by the
     arbitrator(s);

          (x) Judgment upon the award may be entered in any court of competent
     jurisdiction; and

          (xi) The arbitration shall proceed in the absence of a Party who,

     (3) The Base Purchase Price is hereby amended to be $24,652,407.21.
Notwithstanding the provisions of Section 3.1 of the Agreement, Buyers shall be
entitled to a reduction in the Purchase Price, as defined in Section 3.1, by an
amount equal to $1,600,000.00, in addition to the Discount Amount.

     (7) Mention is made that, as provided in paragraph 2 of the Refinery
Contract Extension Agreement dated April 2005, by and between Seller and PACE
Local 4-202 Union, Seller is obligated to pay the lump-sum payment of $900.00 to
all active bargaining unit employees on the payroll as of August 5, 2005 (such
employees being referred to herein as the "Labor Payment Employees" and such
lump-sum payment to each Labor Payment Employee being referred to herein as a
"Labor Payment"). The Assumed Contract Obligations shall include such obligation
of Seller to pay the Labor Payments, subject, however, to the following. Seller
and Buyers have estimated the Labor Payments to be $144,360.00 in the aggregate,
as shown by the calculations set forth in ATTACHMENT A hereto (the "Estimated
Labor Payments"), and the adjustment to the Base Purchase Price as reflected by
the amendment provided for in paragraph (3) hereof includes, in part, a downward
adjustment of the original Base Purchase Price by an amount equal to the
Estimated Labor Payments. On or before August 31, 2005, Refinery Buyer shall
make the Labor Payments and deliver to Seller a statement setting forth (a) the
name of all Labor Payment Employees to whom Labor Payments were made by Refinery
Buyer and (b) the total amount of all Labor Payments (the "Labor Payment
Statement"), which statement shall be accompanied by reasonable supporting
documentation. If the Labor Payments exceed the Estimated Labor Payments, then
Seller shall, within ten (10) Business Days after receipt of the Labor Payment
Statement, make payment to Refinery Buyer by wire transfer of immediately
available funds of the amount of such excess. If the Estimated Labor Payments
exceed the Labor Payments, then Refinery Buyer shall make payment to Seller by
wire transfer of immediately available funds of the amount of such excess on or
before the date of delivery to Seller of the Labor Payment Statement.

     (8) Paragraph (ii) of Section 3.4 of the Agreement is hereby deleted in its
entirety and the following paragraph (ii) of Section 3.4 is hereby substituted
therefor:

          Refinery Buyer acknowledges that, from time to time, Seller enters
into agreements for the future delivery of crude oil necessary for the continued
operation of the

                                        2

<PAGE>

Facility, and that Seller may deem it necessary to enter into such agreements
following the date hereof and through the Closing Date. Refinery Buyer further
acknowledges that some of those agreements require Seller to prepay for such
future deliveries of crude oil and others require that Seller provide the crude
oil supplier with letters of credit issued on behalf of Seller to secure
Seller's obligation to pay for such future deliveries of crude oil ("Crude
Supply LCs"). Prior to Closing, Seller and Buyers shall amend SCHEDULE A-3 to
include any such crude oil supply agreements entered into by Seller as
contemplated in this paragraph (ii) of Section 3.4. At Closing, Seller shall be
entitled to a credit in the Adjustment Statement for such prepayments for crude
oil to the extent such crude oil is not delivered prior to Closing. At Closing,
Refinery Buyer shall cause SunTrust Bank ("SunTrust") to deliver to Wachovia
Bank, National Association ("Wachovia"), irrevocable, standby letters of credit
in an aggregate face amount equal to $60,856,530.00 (being 105% of the amounts
available for drawing under the Crude Supply LCs then outstanding for May crude
plus $38,383,600.00 available for drawing under Crude Supply LCs for April
crude, and such Crude Supply LCs covered by the SunTrust standby letters of
credit being collectively referred to herein as the "Covered Crude Supply LCs"),
such that Wachovia, as issuer of such Covered Crude Supply LCs, may obtain
payment from SunTrust in the event the obligations secured by such Covered Crude
Supply LCs are not paid by Refinery Buyer pursuant to such crude oil supply
agreements, provided that, Refinery Buyer shall be entitled to a credit in the
Adjustment Statement for the amount of the Covered Crude Supply LCs for April
crude, and, provided further, that such credit shall be subject to adjustment
following Closing based upon the actual payments to become due to the crude
supplier for such April crude. Not less than two days prior to the Closing Date,
Seller will provide Refinery Buyer with an estimate of the aggregate amounts of
(a) prepayments for crude oil, (b) Crude Supply LCs and (c) crude oil received
under Crude Supply LCs, as contemplated in this paragraph (ii) of Section 3.4,
which amounts will be calculated by Seller from Sellers' books and records and
reflected in the Adjustment Statement, subject to post-Closing review and
adjustment in accordance with the provisions of Section 3.5.

     (9) Mention is made that, in connection with the Pipeline Capacity Lease
Agreement by and between Seller and Plains Marketing, L.P. ("Plains"), Seller
has paid to Plains a cash deposit of $234,000.00 as security for the performance
of certain obligations of Seller thereunder. Seller and Buyers acknowledge and
agree that the amended Base Purchase Price provided for in paragraph (3) above
includes an upward adjustment of the original Base Purchase Price by an amount
equal to the cash deposit mentioned above in this paragraph and that such
adjustment shall be in lieu of any obligation of Buyers to furnish a replacement
security obligation for the cash deposit held by Plains in connection with such
Pipeline Capacity Lease Agreement.

     (10) Reference is made to those certain crude oil supply agreements listed
on ATTACHMENT B hereto (the "Supply Contracts"). In the event any applicable
Transfer Requirement with respect to any such Supply Contract is not satisfied
prior to the Closing Date, then, pending the satisfaction of such Transfer
Requirement, such Supply Contract shall be held back from the Assets to be
tranferred and conveyed to Refinery Buyer at Closing, without reduction of the
Purchase Price, notwithstanding anything contained in Section 8.2 of the
Agreement to the contrary, provided, however, the following provisions of this
paragraph shall apply. For and with respect to the period following Closing
until such Transfer Requirements are satisfied, CCLLC and Refinery Buyer shall
negotiate in good faith with respect to, and shall

                                        3

<PAGE>

enter into, such lawful arrangements as are reasonably practicable under the
circumstances such that CCLLC shall transfer to Refinery Buyer, and Refinery
Buyer shall assume, all pretax benefits and burdens accruing after the Effective
Time with respect to such Supply Contracts, including, to the fullest extent
reasonably practicable, supply agreements between CCLLC, as seller, and Refinery
Buyer, as buyer, providing for the resale by CCLLC to Refinery Buyer of the
crude purchased by CCLLC under such Supply Contracts for the same price and on
the same terms (to the extent reasonably practicable), including delivery
points, as provided for in such Supply Contracts.

     (11) Seller agrees to include in Seller's payroll for Transferred Employees
for the month of April, 2005, salaries and wages of such Transferred Employees
for Friday, April 29, 2005, even if Closing occurs on that date in which event
the Closing will be effective as of the Effective Time (i.e., 12:01 a.m.,
central time), on that date. Seller and Buyers acknowledge and agree that the
amended Base Purchase Price provided for in paragraph (3) above includes an
upward adjustment of the original Base Purchase Price by an amount equal to
$13,504.81, to reflect Seller's payroll costs for Friday, April 29, 2005.

     (12) Notwithstanding anything to the contrary contained in the Agreement,
imbalances, if any, existing as of the Effective Time with respect to crude oil
or product exchange agreements constituting Assigned Contracts shall be and
remain the right or obligation (as the case may be) of Seller or CCLLC, as
applicable, and Seller or CCLLC, as applicable, shall be solely responsible to
the counterparties to such exchange agreements for any and all balancing
obligations, of whatsoever kind or nature, arising from such imbalances, and
shall be entitled to any and all credits, payments or other entitlements owing
by such counterparties in respect of such imbalances, if any, existing as of the
Effective Time, and no adjustment of the Purchase Price shall be made in respect
of any such imbalances.

     (13) Reference is made to that certain sales contract by and between Seller
and Dufour Petroleum LP listed on ATTACHMENT C hereto. To the extent, if any,
that Dufour Petroleum LP is holding, as of the Effective Time, any cash deposit
securing the performance of any obligations of Seller under such sales contract,
Refinery Buyer agrees to pay to Seller, promptly following request therefor by
Seller in writing (accompanied by reasonable supporting documentation), an
amount equal to such deposit.

     (14) Except as modified and amended hereby, the Agreement shall continue in
full force and effect and Seller and Buyers ratify and confirm the Agreement as
modified and amended hereby.

     IN WITNESS WHEREOF, this Amendment is executed in multiple counterparts,
all of which shall be considered one and the same agreement, as of the date
first above written.
