Item 2.  ACQUISITION OR DISPOSITION OF ASSETS

         Purchase of Diamond-Koch storage assets

         On January 17, 2002, we completed the purchase of various hydrocarbon storage assets from affiliates of
Valero Energy Corporation and Koch Industries, Inc.  The purchase price of the storage assets was approximately
$129 million (subject to certain post-closing adjustments) and will be accounted for as an asset purchase.  The
purchase price was funded entirely by internally generated funds.  The effective date of the purchase was January
1, 2002.

         The storage facilities consist of 30 salt dome storage caverns with a total permitted capacity of 77
million barrels, local distribution pipelines and related equipment.  The facilities provide storage services for
mixed natural gas liquids, ethane, propane, butanes, natural gasoline and olefins (such as ethylene), polymer
grade propylene, chemical grade propylene and refinery grade propylene.  The facilities are located in Mont
Belvieu, Texas and serve the largest petrochemical and refinery complex in the United States.  We will continue
such use of these assets and integrate them into our existing storage operations located in Mont Belvieu.

         Purchase of Diamond-Koch propylene fractionation assets

         On February 1, 2002, we completed the purchase of various propylene fractionation assets from affiliates
of Valero Energy Corporation and Koch Industries, Inc. and certain inventories of refinery grade propylene,
propane and polymer grade propylene owned by such affiliates.  The purchase price of these assets was
approximately $238.5 million (subject to certain post-closing adjustments) and will be accounted for as an asset
purchase.  The purchase price was funded by a drawdown on our existing revolving bank credit facilities.

         The propylene fractionation assets being acquired include a 66.7% interest in a polymer grade propylene
fractionation facility located in Mont Belvieu, Texas, a 50.0% interest in an entity which owns a polymer grade
propylene export terminal located on the Houston Ship Channel in La Porte, Texas and varying interests in several
supporting distribution pipelines and related equipment.   The propylene fractionation facility has the capacity
to produce approximately 45,000 barrels per day of polymer grade propylene.   We will continue such use of these
assets as we integrate them into our Mont Belvieu operations.

         The names of participating lenders under our existing revolving credit facilities are First Union
National Bank, The Chase Manhattan Bank, Bank One, NA, National Australia Bank Limited, Toronto Dominion (Texas),
Inc., Fleet National Bank, The Fuji Bank, Limited, The Dai-Ichi Kangyo Bank, Limited, Bank of Tokyo - Mitsubishi,
Ltd. Houston Agency, SunTrust Bank, Westdeutsche Landesbank Gironzentrale New York Branch, Guaranty Federal Bank
F.S.B., Citibank NA, The Bank of Nova Scotia and Hibernia National Bank.

         Both the storage and propylene fractionation acquisitions have been approved by the requisite regulatory
authorities.  The post-closing purchase price adjustments of both transactions are expected to be completed
during the second quarter of 2002.  A copy of our press releases announcing the completion of the transactions
and both purchase and sale agreements are attached hereto as exhibits.  The filing of this report was not
required until completion of the second transaction raised the combined acquisitions to a level of materiality in
respect to our business.

                    Enterprise Completes Acquisition of Diamond-Koch's Liquid Storage Business

         Houston, Texas - (January 17, 2002) - Enterprise Products Partners L.P. (NYSE:  "EPD") announced that
its operating partnership has completed the acquisition of a natural gas liquids and petrochemical liquids
storage business from Diamond-Koch, L.P. and Diamond-Koch III, L.P., which are both jointly owned by affiliates
of Valero Energy Corporation (NYSE: "VLO") and Koch Industries, Inc.  The purchase price was $129 million in cash.

         The acquired storage facilities consist of 30 salt dome storage caverns with a total permitted capacity
of 77 million barrels.  The facilities provide storage services for mixed natural gas liquids, ethane, propane,
butanes, natural gasoline and olefins, such as ethylene, polymer grade propylene, chemical grade propylene and
refinery grade propylene.  The caverns are located in Mont Belvieu, Texas, and serve the largest petrochemical
and refinery complex in the United States.

         "We are very pleased to acquire this attractive, fee-based storage business," stated O.S. "Dub" Andras,
President and Chief Executive Officer of Enterprise.  "The acquisition of this facility will make Enterprise one
of the leading NGL and petrochemical liquids storage companies in North America.  The addition of this business
will allow us to expand our service capabilities in serving our customers and will provide opportunities to
create value for our partnership through its integration with our network of fractionation, distribution and
import/export terminalling assets on the U.S. Gulf Coast," said Andras.

         Andras continued, "During 2001, we generated over $100 million of cash in excess of the distributions
paid to our partners.  As a result, we will pay for this acquisition using cash on hand and without occurring
additional debt or needing to issue additional equity.  The acquisition should provide annual cash accretion to
our partners of approximately $0.12 per unit on a fully diluted basis.  This acquisition also marks approximately
$750 million of investment that we have made in our fee-based, pipeline and storage business over the past two
years.  All of these assets, which we have either constructed or acquired, integrate into our Gulf Coast system."

         Enterprise Products Partners L.P. is the second largest publicly traded, midstream energy partnership
with an enterprise value of approximately $5 billion.  Enterprise is a leading provider of midstream energy
services to producers and consumers of natural gas and natural gas liquids ("NGLs").  Enterprise's services
include natural gas transportation, processing and storage and NGL fractionation (or separation), transportation,
storage and import/export terminalling.  Enterprise's assets are geographically focused on the United States'
Gulf Coast, which accounts for approximately 55 percent of both domestic natural gas and NGL production and 75
percent of domestic NGL demand.

         This  press  release  includes  forward-looking  statements  within  the  meaning  of  Section  21E of the
Securities  Exchange  Act of 1934  based on the  beliefs  of the  company,  as well as  assumptions  made  by,  and
information  currently available to, management.  Although  Enterprise believes that the expectations  reflected in
such  forward-looking  statements are reasonable,  it can give no assurance that such expectations will prove to be
correct.

2.05     Services Agreement and Ground Leases.  Seller intends (either in the near future or at some later
         date) to sell Seller's interest in the Facility and assets related to Seller's propylene business to the
         Facility Purchaser, which may or may not be Buyer or an Affiliate of Buyer.  Seller has advised Buyer
         and Buyer accordingly agrees that the Storage Assets have been, and are, as of the date of this
         Agreement, operated by the same operator in conjunction with that operator's operation of the Facility
         and related propylene business, and that certain assets, contracts, and services relate to both the
         Storage Assets and the Facility and the related propylene business.

         Attached hereto and incorporated herein by this reference as Exhibit 2.05 is a form of a services
         agreement (the "Services Agreement") that sets forth proposed services to be provided by and between
         Buyer and the owner of the Facility and related propylene business.  If the closing of a sale of the
         Facility and assets related to Seller's propylene business (which for purposes of this Agreement shall
         include a sale of the equity interests in the entities owning such assets) to the Facility Purchaser
         occurs prior to the Closing hereunder, the Services Agreement shall be by and between Buyer and the
         Facility Purchaser.  If the Closing hereunder occurs prior to the closing of a sale to the Facility
         Purchaser, the Services Agreement shall be by and between Buyer and D-K I and will, upon the closing of
         a sale to the Facility Purchaser, be assigned to the Facility Purchaser.  From and after such
         assignment, D-K I shall be relieved of any and all obligations and liabilities accruing on or after the
         effective date of such assignment, and Buyer hereby releases D-K I therefrom.

         Attached hereto and incorporated herein by this reference as Exhibits 2.05A and 2.05B, respectively, are
         a form of a P/P Splitter Facility Ground Lease and a form of an Other Splitter Assets Ground Lease
         (collectively, the "Ground Leases") that provide for the terms upon which the owner of the Facility and
         the related propylene business will lease land for the Facility and other assets used in the related
         propylene business. If the closing of a sale to the Facility Purchaser occurs prior to the Closing
         hereunder, the Ground Leases shall be by and between Buyer and the Facility Purchaser.  If the Closing
         hereunder occurs prior to the closing of a sale to the Facility Purchaser, or if a sale of the Facility
         does not occur, the Ground Leases shall be by and between Buyer and D-K I, and will, upon the closing of
         the sale to the Facility Purchaser, be assigned to the Facility Purchaser.  From and after such
         assignments, D-K I shall be relieved of any and all obligations and liabilities accruing on or after the
         effective date of such assignments, and Buyer hereby releases D-K I therefrom.

         At Closing, Buyer agrees to execute and deliver the Services Agreement and Ground Leases in
         substantially the form of Exhibits 2.05, 2.05A, and 2.05B hereto to D-K I or the Facility Purchaser, as
         appropriate.

         The foregoing assignments are hereby expressly allowed notwithstanding any contrary term contained in
         the Services Agreement or Ground Leases.

2.06     Storage Leases.  Attached hereto and incorporated herein by this reference as Exhibits 2.06A and
         2.06B are forms of storage leases for RGP and PGP (collectively, the "Storage Leases"). If the closing
         of a sale to the Facility Purchaser occurs prior to the Closing hereunder, the Storage Leases shall be
         by and between Buyer and the Facility Purchaser.  If the Closing hereunder occurs prior to the closing
         of a sale to the Facility Purchaser, or if a sale to the Facility Purchaser does not occur, the Storage
         Leases shall be by and between Buyer and D-K I and will, upon the closing of a sale to the Facility
         Purchaser, be assigned to the Facility Purchaser.  From and after such assignment, D-K I shall be
         relieved of any and all obligations and liabilities accruing on or after the effective date of such
         assignment, and Buyer hereby releases D-K I therefrom.  The foregoing assignments are hereby expressly
         allowed notwithstanding any contrary term contained in the Storage Leases.

2.07     Pipeline and Related Easements. The following pipelines are assets used in the propylene business
         and traverse lands to be sold to Buyer hereunder:  (a) a pipeline commonly known as the Texas Eastman
         Pipeline; (b) a four inch (4") RGP Pipeline; (c) a three inch (3") Ethane Pipeline; and (d) a pipeline
         commonly known as the Exxon Pipeline. The foregoing pipelines are collectively called the "Propylene
         Business Pipelines" and are described in Section A of Schedule 2.07 hereto.  Easements covering the
         Propylene Business Pipelines do not exist across Seller's real property.  Buyer will execute and deliver


PAGE 10


         easements for the Propylene Business Pipelines, in substantially the form of the pipeline easement
         attached hereto and incorporated herein by this reference as Exhibit 2.07 (the "Pipeline Easement"), to
         D-K I at the time of Closing hereunder.  Said easements may be assigned to the Facility Purchaser upon
         closing of a sale to the Facility Purchaser, and from and after such assignments, D-K I shall be
         relieved of any and all obligations and liabilities accruing on or after the effective date of such
         assignments, and Buyer hereby releases D-K I therefrom.

         In addition, there are other pipelines and facilities located on, over, or under the lands to be sold to
         Buyer hereunder relating to the Facility.  These pipelines and facilities are collectively called the
         "Ancillary Facility Assets" and are described in Section B of Schedule 2.07 hereto.  Buyer will execute
         and deliver easements for the Ancillary Facility Assets, in substantially the form of the Pipeline
         Easement, to D-K I at the time of Closing hereunder.  Said easements may be assigned to the Facility
         Purchaser upon closing of a sale to the Facility Purchaser, and from and after such assignments, D-K I
         shall be relieved of any and all obligations and liabilities accruing on or after the effective date of
         such assignments, and Buyer hereby releases D-K I therefrom.

         The foregoing assignments are hereby expressly allowed notwithstanding any contrary term contained in
         such easements.

                              PURCHASE PRICE

3.01     Purchase Price.  Subject to the terms and conditions of this Agreement, and in full payment for
         the Storage Assets, Buyer shall pay to Seller at Closing, by wire transfer as described in Section
         8.01(d)(i), the sum of One Hundred Twenty-nine Million Dollars ($129,000,000.00), as such sum may be

         7.01 (the "Purchase Price").

3.02     Adjustments to the Purchase Price.

        (a)      Closing Purchase Price Adjustment.  Subject to final adjustment pursuant to the provisions of
                  Article VII, the Purchase Price shall initially be adjusted at Closing as follows.

                           and expenses identified on Schedule 3.02(a)(i) to the extent such items and expenses
                           are paid prior to the Effective Time which inure to the benefit of the Storage Assets
                           after the Effective Time and (B) decreased to reflect amounts and expenses identified
                           on Schedule 3.02(a)(i) paid after the Effective Time which inure to the benefit of the
                           Storage Assets before the Effective Time.

                  (ii)     Prorations.  Real estate and personal property taxes for the calendar year January 1, 2002
                           through December 31, 2002, shall be prorated to the Effective Time based upon the
                           amounts of real estate and personal property taxes allocated to the Storage Assets
                           from the most recent property tax assessments if known, or upon the amounts paid

                           Purchase Price.  Buyer will assume responsibility for the actual payment to the
                           applicable Governmental Body of any unpaid property taxes not yet due and which relate
                           to periods after the Effective Time.  Seller shall remain liable for unpaid property
                           taxes to the extent they relate to periods prior to the Effective Time and for which
                           there has not been a reduction in the Purchase Price pursuant to this Section

                           Date calculated at the rate of Five Percent (5%) per annum.

         (b)      Post-Closing Purchase Price Adjustment. The Purchase Price shall be subject to adjustment
                  subsequent to the Closing Date in the manner respectively provided in Sections 6.10 and 7.01.

                  and deliver to Buyer a statement of the estimated Purchase Price adjustments to be made at

                  actual numbers are not available, this Closing Statement will be based upon the prior month's
                  Storage Assets-related financial statements.

         (c)      except as set forth on Schedule 4.02, constitute a breach or default (with or without notice or lapse of
                  time or both) under, or permit the termination of, any Transferred Contract or Material
                  Instrument or result in the creation of any Lien upon any of the Storage Assets; or

         except as that enforceability may be (i) limited by any applicable bankruptcy, insolvency,
         reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and
         (ii) subject to general principles of equity (regardless of whether such enforceability is considered in

         Seller, all of the Material Contracts that are necessary for operation of the Storage Assets in the
         manner and fashion they are being operated by Seller as of the date of this Agreement.  Except as set
         forth in Schedule 4.06, Seller has not received written notice that it is in default under the terms of


PAGE 12

         any Transferred Contract, nor that any event has occurred which, with the passage of time or giving of
         notice, or both, would constitute such a default.  Except as provided for in Schedule 4.06, to the
         Knowledge of Seller, no third party is in material default under the terms of any Transferred Contract,
         nor does Seller have Knowledge of any event that has occurred which, with the passage of time or giving
         of notice, or both, would constitute such a default of a third party.  Except as provided for in
         Schedule 4.06, the Transferred Contracts are in full force and effect and are binding upon Seller and
         all other parties thereto in accordance with their terms.  Except as provided for in Schedule 4.06, none
         of the other parties to any Transferred Contract has notified Seller that it intends to terminate, not
         renew or alter the provisions thereof by reason of the transaction contemplated by this Agreement or
         otherwise.  True and correct copies of all Transferred Contracts have been delivered to Buyer, which
         delivery is hereby acknowledged by Buyer.

4.07     Permits.  Except for permits under the definition of Material Instruments in Section 4.08, the
         Permits (as listed on Schedule 4.07) are all of the permits, licenses, orders, or authorizations issued
         by a Governmental Body that are presently held by Seller or by its Affiliates and that relate to the
         ownership, use, or operation of the Storage Assets as currently owned, used and operated by Seller.

4.08     Real Estate Interests.  Schedule 4.08 sets forth a list of all deeds, leases, easements and
         rights-of-way of real property in connection with the Storage Assets, to which Seller is either a party
         or a successor-in-interest (the "Material Instruments").  Except as set forth in Schedule 4.08, Seller
         has not received written notice that it is in default under the terms of any Material Instrument, nor
         that any event has occurred which, with the passage of time or giving of notice, or both, would
         constitute such a default.  Except as provided for in Schedule 4.08, to the Knowledge of Seller, no
         third party is in material default under the terms of any Material Instrument, nor does Seller have
         Knowledge of any event that has occurred which, with the passage of time or giving of notice, or both,
         would constitute such a default of a third party.

4.09     Intellectual Property Interests. To the Knowledge of Seller, Schedule 2.01(h) sets forth a list
         of all Intellectual Property Interests which burden or benefit the operation, use or maintenance of the
         Storage Assets.  Except as set forth in Schedule 2.01(h), Seller is the owner of, or duly licensed to
         use, each Intellectual Property Interest listed on Schedule 2.01(h), and there are no Orders limiting
         Seller's rights to use the Intellectual Property Interests or determining that Seller's possession or
         use thereof infringes upon any Person's rights; nor, to the Knowledge of Seller, are there any
         Proceedings pending or threatened in writing in which any Person seeks to limit Seller's rights with
         respect to the Intellectual Property Interests or claims infringement by Seller as a result of Seller's
         use or possession of such Intellectual Property Interests. Subject to any consent required as referenced
         in Section 6.07, the consummation of the transactions contemplated by this Agreement will not result in
         the impairment of the Buyer's right to use any such Intellectual Property Interests or infringe upon the
         Intellectual Property Interests of any third Person.

4.10     Tax Matters.

         (a)      All Returns required to be filed with respect to any Tax for which (x) Seller is liable, or any other
                  Person is liable on account of owning a direct or indirect interest in Seller (a "Seller
                  Owner"), and (y) Buyer, as the successor owner of the Storage Assets, reasonably could be

                  Owner have timely filed true, correct and complete declarations of estimated Subject Tax in
                  each jurisdiction that requires any such declaration to be filed by them.

         (b)      Except as provided for in Schedule 4.10, no audit, assessment (other than on the basis of a Return as
                  filed) or litigation with respect to any Subject Tax is pending or, to the Knowledge of Seller,
                  threatened in writing, and no basis which Seller believes to be valid exists on which any Claim


PAGE 13

                  for any such Subject Tax can be asserted against Seller, any Seller Owner, the Storage Assets
                  or Buyer as the successor owner of the Storage Assets.

         (c)      Except as provided for in Schedule 4.10, no requests for rulings or determinations in respect of any
                  Subject Taxes are pending between Seller or any Seller Owner and any Governmental Body.

         (d)      No extension of any period during which any Subject Tax may be assessed or collected and for which
                  Seller or any Seller Owner is or may be liable has been granted to any Governmental Body.

         (e)      All amounts required to be withheld by Seller or any Seller Owner and paid to governmental agencies for

                  Seller and each Seller Owner have made all deposits applicable law requires them to make in
                  connection with the operation of the Storage Assets with respect to withholding and other
                  employment taxes with respect to their employees.

         (f)      Seller is not a "foreign person" within the meaning of Section 1445(f)(3) of the Code.

         (g)      None of the Storage Assets is (i) for federal Tax purposes, an interest in a partnership, corporation,
                  trust or other entity, or (ii) for any relevant Tax purpose, an interest in an entity, separate
                  from Seller, upon which any liability for Tax is imposed by applicable law.

4.11     Compliance.  Except as set forth on Schedule 4.11:

         (a)      Seller has granted no options to purchase, sublease, or otherwise acquire any interest in the Storage
                  Assets, and Seller has the right of possession of the Storage Assets.

         (b)      To the Knowledge of Seller, the present use of the Storage Assets is in substantial conformity with all
                  applicable existing Orders and Legal Requirements and with all deed restrictions of record, and
                  Seller has not received written notice of any violation or alleged violation of the foregoing.

4.12     Environmental. To the Knowledge of Seller, and except as listed on Schedule 4.12, there is
         neither any pending environmental Proceeding with respect to the Storage Assets nor has there been any
         treatment, storage, release or disposal of Hazardous Material with respect to the Storage Assets at, on,
         or under any of the Storage Assets or any third-party premises in violation of any Environmental Law.
         Except as listed on Schedule 4.12, Seller has not received any written notice from any Governmental Body
         of any alleged violation of any Environmental Law or any Environmental Contamination involving the
         Storage Assets.  To the Knowledge of Seller, there exist no studies, whether prepared by Seller's
         employees or by third parties, in Seller's possession relating to the presence or absence of asbestos or
         asbestos-containing materials on the Storage Assets.

4.13     Financial Statements.  Buyer has been provided certain financial information relating to the
         ownership and operation of the Storage Assets for the period commencing January 1, 1999 through December
         31, 2000, including a balance sheet reflecting the assets and liabilities in respect of the Storage
         Assets as of November 30, 2001 and a statement of operations reflecting the results of operations of the
         Storage Assets for the 11-month period ending November 30, 2001 (collectively, the "Storage Assets
         Financial Information").  The Storage Assets Financial Information fairly presents the results of
         Seller's ownership and operation of the Storage Assets as of the dates and for the periods therein
         specified. The books of account on which the Storage Assets Financial Information is based have been
         kept accurately in the ordinary course of business, the transactions entered therein represent bona fide
         transactions and the revenues, expenses, assets and liabilities of Seller have been properly recorded in
         such books.

4.14     Employees.  Seller does not have any employees or does not maintain or is not liable under any
         employee compensation, benefit, pension or welfare plan or arrangement.  None of the employees involved


PAGE 14

         in operating the Storage Assets are covered by collective bargaining agreements and, to the Knowledge of
         Seller, there are no such organizational efforts respecting such employees.

4.15     Capital Projects.  Schedule 4.15(a) contains a complete and accurate summary description of all
         capital projects relating to the Storage Assets currently in progress, and all capital projects
         currently planned, by Seller, and Schedule 4.15(b) contains a list of such projects that Seller
         reasonably expects will not be completed as of the Effective Time and which Buyer will therefore
         complete from and after the Effective Time (the "Capital Projects").

4.16     Preferential Rights.  To the Knowledge of Seller, Schedule 4.16 lists all contracts or agreements
         containing preferential purchase rights or rights of first refusal or similar rights with respect to the
         Storage Assets.

                                   ARTICLE VI
                                 COVENANTS

6.01     Casualty Loss/Condemnation.

        (a)      Casualty Loss.  Prior to Closing, if all or any portion of the Storage Assets have been or are
                  destroyed by fire, flood, storm, or other casualty of a similar nature (all of which are herein
                  called a "Casualty Loss"), Seller will promptly give written notice of such Casualty Loss to
                  Buyer.  If such Casualty Loss is reasonably determined to require repairs that will cost in
                  excess of twenty-five percent (25%) of the Purchase Price, then either Party shall have the
                  right and option to declare this Agreement to be terminated by written notice given to the
                  other Party within thirty (30) days after Seller's notice of such Casualty Loss was given to
                  Buyer.  Should such damage not be to such extent or should it be to such extent but neither
                  Party elects to so terminate this Agreement, then Seller shall proceed, at its sole expense, to
                  repair any such damage or destruction as soon as is reasonably practicable to the condition as
                  existed immediately prior to such Casualty Loss, and upon Buyer's reasonable satisfaction that
                  such repair has been completed in accordance with the terms of this Agreement, the transaction
                  contemplated hereby will close, subject to the other terms of this Agreement. Any insurance
                  proceeds attributable to a Casualty Loss occurring while Seller has the risk of loss shall be
                  the sole property of Seller. The risk of Casualty Loss occurring after Closing with respect to
                  the Storage Assets shall pass to Buyer at Closing.

        (b)      Condemnation.  If, prior to Closing, all or a portion of the Storage Assets sufficient to cause a
                  material adverse effect with respect to the operation of the Storage Assets are taken or
                  threatened in writing to be taken by condemnation proceedings, then Seller will promptly give
                  written notice of such condemnation or condemnation proceedings to Buyer and Buyer may
                  terminate this Agreement upon prior written notice to Seller of at least fourteen (14) days or
                  the number of days left until Closing, whichever is fewer.  If Buyer terminates this Agreement
                  under this Section 6.01(b), any payments made under threat of condemnation or condemnation
                  awards shall be the sole property of Seller.  If Buyer does not elect to terminate this
                  Agreement, or cannot terminate this Agreement because the taking did not have a material
                  adverse effect, such payments or awards shall be the sole property of Buyer.

         6.02     Conduct Since the Effective Time.

         (a)      Since the Effective Time, Seller has (i) conducted its business in the ordinary course in substantially
                  the same manner as it was conducted at the Effective Time and (ii) made all reasonable efforts
                  consistent with past practices to maintain the Storage Assets in substantially the same
                  condition (except for normal wear and tear) existing at the Effective Time and preserve its
                  relationships with customers, suppliers and others (except Seller's Affiliates) with whom
                  Seller deals, provided that Seller has advised Buyer, and Buyer accordingly agrees, that Seller
                  may terminate service agreements with contractors who may work at the Storage Assets pursuant
                  to Seller's "General Contracts," "Intermittent Services Agreements," or similar agreements (the
                  "Interim Services Agreements") because the same pertain to other assets and businesses not
                  being sold hereunder.  Schedule 6.02 contains a list of the Interim Services Agreements.
                  Seller shall notify Buyer promptly of any addition to the list of Interim Services Agreements.

         (b)      Without the consent of Buyer (which consent will not be unreasonably withheld, delayed, or conditioned),
                  and since the Effective Time, Seller has not, shall not, and shall not commit or agree to, do
                  any of the following:

                  (i)      waive, compromise, or settle any right or Proceeding or any Liabilities/Claims in respect thereof in
                           excess of One Hundred Thousand Dollars ($100,000.00) to the extent the foregoing
                           relate to the Storage Assets for which Buyer will assume liability hereunder;

                  (ii)     incur obligations with respect to, or undertake any transactions relating to, the Storage Assets other
                           than transactions (1) in the normal, usual, and customary manner, (2) of a nature and


PAGE 16

                           in an amount consistent with prior practice, and (3) in the ordinary course of
                           business of owning and operating the Storage Assets;

                  (iii)    other than mechanics', materialmen's, and similar liens arising from goods or services provided in the
                           ordinary course of operating the Storage Assets, directly or indirectly, create,
                           incur, or assume any Lien on or with respect to any Storage Assets, or any income or
                           profits therefrom;

                  (iv)     enter into or agree to any agreement or arrangement granting any rights to purchase any of the Storage
                           Assets or the general or limited partnership interests of Seller;

                  (v)      enter into any new Material Contract, Material Instrument or Permit or terminate or modify any Material
                           Contract, Material Instrument or Permit listed on Schedules 4.07 or 4.08; provided,
                           that with respect to Material Instruments, Seller may enter into new Material
                           Instruments either in the ordinary course of business or with respect to Material
                           Instruments under Section 6.06 so long as the same do not commit Buyer to any ongoing
                           monetary obligation in excess of One Hundred Thousand Dollars ($100,000.00) in the
                           aggregate; or

                  (vi)     except as specifically provided for herein, transfer, or agree to transfer, any part of the Storage
                           Assets.

6.03     Compliance with Conditions Precedent.  Each Party shall use its commercially reasonable efforts
         to cause the conditions precedent to Closing set forth in Sections 8.02 and 8.03, applicable to such
         Party, to be fulfilled and satisfied as soon as practicable but in any event prior to Closing.

6.04     Press Release.  Buyer and Seller shall consult with each other with regard to all publicity and
         other releases issued at or prior to Closing concerning this Agreement and the transactions contemplated
         hereby, and except as required by Legal Requirements, neither Party shall issue any publicity or other
         release without the prior written consent of the other Party.

6.05     Government Filings.  After the Closing Date, Buyer shall promptly file with the applicable
         Governmental Bodies all filings necessary to change Seller's or any of Seller's Affiliates from the
         owner and/or operator of the Storage Assets to Buyer or its designee and shall promptly provide Seller
         with copies of all such filings when made and confirmation thereof when received.  Buyer shall reimburse
         Seller for all filing and related fees should Seller incur such fees.

6.06     Consents to Assignment-- Formation of Diamond-Koch.  Schedule 6.06 lists the Transferred
         Contracts and Material Instruments for which consent or approval to assignment is required, that were to
         be assigned to D-K I or D-K III in connection with the formation of the Diamond-Koch venture of which
         D-K I and D-K III are a part, and with respect to which such consent or approval is not yet complete.
         Seller shall, at Seller's sole cost and expense, use reasonable commercial efforts and diligence to
         obtain all such required consents or approvals and deliver evidence of same reasonably satisfactory to
         Buyer as soon as reasonably practicable.  If all required consents or approvals have not been obtained
         as of Closing (or, despite Seller's reasonable and diligent commercial efforts, are not later obtained)
         with respect to Contracts and Material Instruments (collectively, the "Formation Non-Conveyed
         Contracts"), Seller shall take commercially reasonable steps and actions to provide Buyer, as of the
         Effective Time, with the benefit of such Formation Non-Conveyed Contracts.  Buyer shall enter into
         subcontracting or other beneficial arrangements with Seller or an Affiliate thereof pursuant to which
         Buyer shall fulfill such obligations or liabilities at no additional expense to Seller except Seller's
         own costs in entering into, administering, and managing such arrangements.  Notwithstanding the
         foregoing in this Section 6.06, Buyer shall have no obligation, and Seller shall have a continuing
         obligation to use reasonable commercial efforts and diligence, to obtain any consents or approvals with
         respect to Formation Non-Conveyed Contracts.  Any and all cost and expense relating to such consents or
         approvals shall be Seller's sole obligation.

6.07     Consents to Assignment-- Sale to Buyer.

         (a)      Obtaining Consents.  If the purchase and sale contemplated by this Agreement requires that
                  consent or approval be obtained prior to any transfer or assignment of Storage Assets, Buyer
                  (except to the extent of Seller's undertakings with respect thereto as described in this
                  Section 6.07) shall be responsible, at its sole cost, for obtaining such consent or approval.
                  To the Knowledge of Seller, Schedule 6.07 lists all of the consents and approvals required to
                  be obtained prior to any transfer or assignment of the Storage Assets to Buyer.  Subject to the
                  last sentence of this Section 6.07(a), commencing with the execution of this Agreement, Seller
                  will: (i) use reasonable diligence to prepare appropriate requests for consent and consent
                  forms and documents with respect to the documents listed on Schedule 6.07 hereto and will
                  provide the same to the Persons from whom consent is required;  (ii) use reasonable diligence
                  to obtain as many consents as are possible prior to Closing and shall provide all documents
                  reflecting consents that have been obtained to Buyer at Closing; and (iii) upon Closing, turn
                  over to Buyer its files relating to its efforts to obtain such consents.  Buyer shall
                  thereafter be responsible for completing all work required to complete the process of obtaining
                  such consents and will continue to exercise reasonable diligence to secure such consents.  If
                  all required consents or approvals have not been obtained as of Closing (or, despite Buyer's
                  reasonable and diligent commercial efforts, are not later obtained) with respect to Contracts
                  and Material Instruments (collectively, the "Non-Conveyed Contracts"), Seller shall, promptly
                  following Buyer's written request, take commercially reasonable steps and actions to provide
                  Buyer with the benefit of such Non-Conveyed Contracts.  Buyer shall enter into subcontracting
                  or other beneficial arrangements with Seller or an Affiliate thereof pursuant to which Buyer
                  shall fulfill such obligations or liabilities at no additional expense to Seller except
                  Seller's own costs in entering into, administering, and managing such arrangements.  Seller's
                  obligation to provide such benefit with respect to a particular Non-Conveyed Contract shall
                  expire concurrently with the earlier of (a) the expiration of that Non-Conveyed Contract
                  according to its terms or (b) with respect to Non-Conveyed Contracts that are not Material
                  Instruments, the earliest time that such Non-Conveyed Contracts may be terminated by Buyer (as
                  Seller's assignee) without breach thereof.  Notwithstanding anything to the contrary provided
                  for in this Section 6.07(a) above, if the Closing occurs within five (5) Business Days after
                  the date of this Agreement, Seller need not perform the covenants provided for in the second
                  sentence of this Section 6.07(a), and Buyer shall be responsible for initiating and completing
                  the consent requests described herein; provided, that Seller shall use commercially reasonable
                  efforts to obtain the consents and approvals indicated by an "**" on Schedule 6.07 as soon as
                  possible after the Closing.

         (b)      Pending Consent.  If there are prohibitions against or conditions to the conveyance of
                  any of the Storage Assets without the prior written consent of third parties, including,
                  without limitation, Governmental Bodies (other than consents of a ministerial nature which are
                  normally granted in the ordinary course of business), which if not satisfied, waived, released,
                  or terminated would result in a breach of such prohibitions or conditions or would give an
                  outside party the right to terminate Buyer's rights with respect to such assets (herein called
                  a "Restriction"), then any provision contained in this Agreement to the contrary
                  notwithstanding, the transfer of title to or interest in each such asset (herein called the
                  "Restricted Asset") pursuant to this Agreement shall not become effective unless and until such
                  Restriction is satisfied, waived or no longer applies.  When and if such a Restriction is so
                  satisfied, waived or no longer applies, to the extent permitted by applicable law and any
                  applicable contractual provisions, the assignment of the Restricted Asset subject thereto shall
                  become effective automatically as of the Effective Time, without further action on the part of
                  Seller or Buyer.

6.08     Insurance.  Seller shall keep, or cause to be kept, all insurance policies on the Storage Assets
         in full force and effect through the close of business on the Closing Date.

6.09     Conveyance of Fee and Other Property.  Seller shall convey to Buyer, at Closing, the fee property
         described on Schedule 2.01(e) hereto by Special Warranty Deed in the form of Exhibit 8.01(a)-I hereto.


PAGE 18

         Seller will also convey property pursuant to the Assignment in the form of Exhibit 8.01(B)-II.
         Notwithstanding any warranty of title arising by operation of law, including under any statute or any
         decision of any court in the state of Texas, Seller's conveyance to Buyer of such fee property and other
         property shall be subject to all Permitted Encumbrances.  The foregoing covenant shall survive the
         closing of the transactions contemplated by this Agreement and shall survive delivery of such Special
         Warranty Deed and Assignment from Seller to Buyer.

6.10     Product Storage Verification and Adjustments.  Product storage verification and adjustment shall
         be completed as provided for in Exhibit 6.10 attached hereto and incorporated herein by this reference.

6.11     Inspection.  Prior to Closing, at any reasonable time and from time to time upon
         reasonable advance notice to Seller's Vice President of Operations, Seller shall permit the
         representatives of Buyer to inspect the Storage Assets and observe the operating and maintenance
         personnel therein employed, and to further observe any and all activities related to the maintenance,
         operation, contracting, and administration thereof.  Buyer's representatives shall be entitled to make
         copies of any Records.  Notwithstanding the foregoing, Seller shall not be required to grant access to
         or furnish information which Seller considers, in its sole judgment, to be confidential to Seller or to
         others or which might disclose any techniques or applications which Seller considers to be business
         secrets or proprietary information to Seller.  All information furnished to Buyer pursuant to this
         provision will be deemed to be "Confidential Information" for purposes of that certain "Confidentiality
         Agreement" described in Section 12.03 below.  All inspections shall be conducted in compliance with all
         of Seller's safety procedures, rules, and regulations in effect at the Storage Assets from time to time,
         which shall include, without limitation, site safety training and access restriction procedures as are
         normally required by Seller of third party invitees.  No investigation by Buyer will affect any
         representation or warranty given by Seller to Buyer or the remedies available to Buyer hereunder.

                                  ARTICLE VII
                          POST-CLOSING AGREEMENTS

7.01     Final Recapitulation Settlement; Subsequent Audits and Settlements.  With respect to final
         recapitulation and audits:

         (a)      Within ninety (90) days after the Closing (the "Final Recap Date"), Seller shall provide to Buyer, for
                  Buyer's review, a proposed final recapitulation settlement in the form of the Closing Statement
                  (the "Final Recap Statement") to account for all actual adjustments to the Purchase Price known
                  as of the Final Recap Date if such actual adjustments differ from those shown on the Closing
                  Statement provided prior to Closing pursuant to Section 3.02(c) (the "Final Recap").  Buyer
                  shall have the right, within thirty (30) days after receipt of the Final Recap Statement, to
                  audit the Final Recap Statement.  If Buyer disagrees with the Final Recap Statement, Buyer and
                  Seller shall use their respective commercially reasonable efforts to reach agreement within
                  thirty (30) days following Buyer's completion of its audit of the Final Recap Statement.

         (b)      Should the Parties be unable to resolve any disagreements, such disagreement shall, at the earliest
                  practicable date, be referred, by either or both of the Parties, to a nationally recognized
                  accounting firm mutually acceptable to Buyer and Seller (the "Accounting Firm"), along with all
                  audit reports, work papers, schedules, and calculations related to the matter in dispute.
                  Within twenty-five (25) days after such submission, the Accounting Firm shall issue a letter
                  report determining the Final Recap which shall be final and binding.  Any fees and expenses
                  incurred in resolving disputes shall be borne by the Party incurring such, except for the
                  Accounting Firm which shall be borne equally by the Parties.

         (c)      Payment of any amounts owed under the Final Recap is due within ten (10) days after the date Seller and
                  Buyer agree on the Final Recap Statement, or within ten (10) days after the determination of
                  the Final Recap by the Accounting Firm, whichever is later.

7.03     Recording. Except for the recording of the assignments described in Section 6.06, Buyer shall be
         solely responsible for promptly recording the assignments and any other instruments related to the
         conveyance of any of the Storage Assets and shall promptly furnish Seller with the recording
         information.  All recording and filing fees for instruments to be recorded by Buyer shall be paid by
         Buyer.

7.04     Files and Records.  At or prior to the Closing Date, Seller, to the extent permitted, shall
         permit Buyer to take possession of the original Records relating to the Storage Assets in Seller's
         possession to the extent the same are located at Seller's Mont Belvieu, Texas or Houston, Texas
         offices.  Other Records shall be made available to Buyer within thirty (30) days after the Closing Date
         at either Mont Belvieu, Texas or Houston, Texas, as designated by Buyer; provided, however, that Seller
         shall, if reasonably needed by Buyer, make copies of such other Records available to Buyer upon Buyer's
         request prior to such time at the sole expense of Seller.  With regard to the accounting records that
         are not part of the Records, including all records that Buyer and Enterprise Products Partners L.P. may
         need in order to prepare financial statements in accordance with generally accepted accounting
         principles for filing with the Securities and Exchange Commission, Seller shall make available to Buyer
         such records for inspection and copying during normal business hours.  From time to time as requested by
         Seller, Buyer shall make the Records which it takes possession of available to Seller for inspection and
         copying during normal business hours, together with such additional files, data, and records of Buyer as
         may be reasonably requested by Seller in order to pursue any claims, obligations, and disputes relating
         to the Storage Assets.  If there are records that relate to the Excluded Assets that also relate to the
         Storage Assets, Seller shall have the right to redact any information contained therein that relates
         exclusively to the Excluded Assets.

7.05     Use of Seller's Name.  By no later than sixty (60) days after Closing, Buyer shall have removed
         or caused to have been removed the names and marks used by Seller (including replacement of Seller's
         name and number on any applicable pipeline markers) and all variations and derivations thereof and logos
         relating thereto from the Storage Assets.  After expiration of such time period specified above, Buyer
         shall not make any use whatsoever of those names, marks, and logos.  If Buyer has not completed such
         removal within sixty (60) days after Closing, Seller shall have the right, but not the obligation, to
         take such steps as are required to complete such name change and removal or cause such name change and
         removal to be completed and Buyer shall reimburse Seller for any costs or expenses incurred by Seller in
         connection therewith.

7.06     Collections.  Because the Effective Time is occuring prior to the Closing Date, Seller has
         collected, or may collect, revenues attributable to the Storage Assets arising from post-Effective Time
         operations.  Similarly, Seller has paid, or may pay, amounts attributable to post-Effective Time
         operations of the Storage Assets.  The net amounts of the foregoing revenues and expenditures are
         hereinafter called the "Net Operating Cash Flow" or "Net Operating Cash Deficit," as the case may be.
         Therefore, within five Business Days after completion by Koch Hydrocarbon, LP of accounting for the
         Storage Assets for January, 2002's business, pursuant to the terms of that certain Transition Services
         Agreement of even date herewith (except that such accounting shall be made on a cash basis), Seller will
         pay, if applicable, the Net Operating Cash Flow to Buyer or, if applicable, Buyer will pay the Net
         Operating Cash Deficit to Seller.  Except as already accounted for in the Net Operating Cash Flow or Net
         Operating Cash Deficit described above, after Closing, Seller agrees to cause to be paid to Buyer any
         amounts received by Seller (whether received before or after the Effective Time), including payments on
         accounts receivables generated by the Storage Assets after the Effective Time, to which Buyer is
         entitled but which is paid instead to Seller for whatever reason. Except as already accounted for in the
         Net Operating Cash Flow or Net Operating Cash Deficit described above, after Closing, Buyer agrees to
         cause to be paid to Seller any amounts received by Buyer after the Effective Time, including payments on
         accounts receivables generated by the Storage Assets prior to the Effective Time, to which Seller is
         entitled but which are paid instead to Buyer for whatever reason.

7.07     Repermitting.  Seller has filed applications (the "Applications") for new Texas Railroad
         Commission ("TRRC") permits allowing use of the five (5) Storage Wells described in Schedule 7.07 (the
         "Repermitted Wells") in substantially the manner, for substantially the term, and for substantially the
         capacity reflected in the Applications, subject to reasonable modifications of such Applications and the
         permits resulting therefrom as may be required by the TRRC.  After Closing, Buyer will use all
         commercially reasonable efforts to diligently prosecute the Applications to a successful conclusion


PAGE 20


         before the TRRC.  Such efforts shall include, but not be limited to, agreeing to modifications necessary
         to meet reasonable objections that the TRRC may have or reasonable modifications that the TRRC may
         require in order to issue such permits.  All such actions shall be at Buyer's sole cost and expense.  If
         Buyer shall have obtained such new permits for three (3) or more of the Repermitted Wells by the first
         anniversary of the Closing or such later date as may be agreed pursuant to this Section 7.07 (the
         "Repermitting Date"), then Seller shall owe Buyer no payment under this Section 7.07.  If Buyer shall
         have obtained such new permits for only two (2) of the Repermitted Wells by the Repermitting Date, then
         Seller shall pay to Buyer Five Million Dollars ($5,000,000.00) in cash.  If Buyer shall have obtained
         such new permits for only one (1) of the Repermitted Wells by the Repermitting Date, then Seller shall
         pay to Buyer Ten Million Dollars ($10,000,000.00) in cash.  If Buyer shall have failed to obtain new
         permits for any of the Repermitted Wells by the Repermitting Date, then Seller shall pay to Buyer
         Fifteen Million Dollars ($15,000,000.00).  Any such payments by Seller to Buyer pursuant to this Section
         7.07 shall be due and payable by Seller on or before the fifth Business Day following the Repermitting
         Date.  Should such a permit(s) not be obtained by the Repermitting Date, but should there remain a
         reasonable likelihood that such a permit(s) can be thereafter obtained on terms set forth in the
         Application(s), subject to such reasonable modification, Buyer shall agree to extend the Repermitting
         Date and shall agree to further extensions so long as such a reasonable likelihood exists.  At such time
         as such a reasonable likelihood does not exist, any extended Repermitting Date shall end and the
         provisions for possible payment by Seller to Buyer (if Buyer is unable to obtain permits for three (3)
         or more of the Repermitted Wells) shall be triggered.   Buyer shall also, promptly after the Effective
         Time, substitute itself as a party on the other TRRC permit applications pertaining to all other Storage
         Wells (other than the Repermitted Wells) and shall be responsible, at its sole cost and risk, to obtain
         any permits necessary from the TRCC relating to such other Storage Wells.  Buyer retains sole discretion
         in whether to use commercially reasonable efforts to prosecute an Application, but if it is determined
         that Buyer has failed to use such commercially reasonable efforts, the permit(s) for the Repermitted
         Well(s) related to such Application(s) shall be deemed to have been granted for purposes of this Section
         7.07.  Such deemed granting of the permit(s) shall be Seller's sole remedy for Buyer's failure to use
         commercially reasonable efforts to prosecute such Application(s), and no payments will be due to Buyer
         under this Section with respect to Repermitted Wells for which such Applications are deemed granted
         hereunder .

7.08     Further Assurances.  Each Party shall, from time to time at the reasonable request of the other,
         and without further consideration, execute and deliver such other instruments of sale, transfer,
         conveyance, assignment, clarification, and termination, and take such other action as the Party making
         the request may reasonably require to effectuate the intentions of the Parties, including those required
         to sell, transfer, convey, and assign to and vest in Buyer, and to place Buyer in possession of the
         Storage Assets, and to transfer, assign, or convey the Excluded Assets and Excluded Liabilities to
         Seller.  Seller intends to convey the Storage Assets at Closing; provided, however, that in the event it
         is determined after Closing that:  (i) any part of the Storage Assets were not owned by Seller and that
         the title to any part of the Storage Assets is incorrectly in the name of another entity, or (ii) any
         Excluded Asset is conveyed to Buyer and that the title to such Excluded Asset is incorrectly in the name
         of Buyer, then each Party shall take all such action necessary to promptly and correctly convey any part
         of the Storage Assets to Buyer, or any part of the Excluded Assets to Seller.

                                  ARTICLE VIII
                                           CLOSING

         Sections 8.02 and 8.03 have been either met or waived.  The Closing shall be deemed to be effective as

                  all material respects in accordance with their terms on and as of the Closing with the same
                  effect as though such representations and warranties have been given on and as of the Closing
                  and, if any Schedules attached hereto have been supplemented since the date of this Agreement,
                  any such supplementation shall not, in Buyer's reasonable discretion, taken as a whole, have a
                  material adverse effect on the Schedule at issue or on the representation or warranty to which
                  it pertains.  Seller shall also have performed or complied with, in all material respects, all
                  of its obligations under this Agreement which are to be performed or complied with by it as of
                  the Closing.

                  thereof by any Governmental Body, (iii) any Legal Requirement, or (iv) any Proceeding, which in
                  all reasonable likelihood, might prohibit or render illegal, Buyer's consummation of the
                  transactions contemplated herein.

         (c)      [Intentionally Left Blank]

                  representations and warranties in Article IV are true and accurate in all material respects in

                  been supplemented since the date of this Agreement, any such supplementation does not, taken as

                  warranty to which it pertains, and further certifying Seller's compliance with Seller's
                  covenants and agreements herein.

         (g)      Seller shall deliver to Buyer certificates executed by an officer of Koch Industries, Inc. and Valero

                  and authorizing execution of the guaranty by each Person signing the same on behalf of the
                  Seller Guarantors, and further certifying that such resolutions and such authority have not
                  been modified and remain in effect.

         (j)      D-K I and/or the Facility Purchaser, as the case may be, shall have executed and delivered the Services

         (k)      No material adverse effect (which shall not include any effect resulting from a change in general

9.01     Disclaimer.  Except as specifically set forth in this Agreement, Buyer:

         (a)      acknowledges and agrees that Seller has not made, does not make, and expressly disclaims any warranties,
                  representations, covenants, or guarantees, either express or implied, whether arising by
                  operation of law or otherwise, as to the merchantability, habitability, quantity, quality,
                  environmental condition, or physical condition of the Storage Assets or their suitability or
                  fitness for any particular purpose or use;

         (b)      without limiting any indemnity obligations of Seller contained in Section 9.02(a), affirms that: (i) it
                  has investigated and inspected the Storage Assets and is familiar and satisfied with their
                  physical condition, and (ii) has made its own determination as to the: (a) merchantability,
                  habitability, quantity, quality, and physical condition of the Storage Assets and (b) the
                  Storage Assets' suitability or fitness for any particular purpose or use;

         (c)      except to the extent of Seller's indemnity obligations under Section 9.02(a), hereby accepts the Storage
                  Assets in their present environmental condition and physical condition on an "AS IS," "WHERE
                  IS," and "WITH ALL FAULTS AND DEFECTS" basis (including with respect to Seller's title thereto,
                  except as otherwise provided for in this Agreement), regardless of how such faults and defects


PAGE 25


                  were caused or created (by Seller's negligence, actions, omissions, fault, or otherwise), and
                  acknowledges that: (i) without this acceptance, this sale would not be made, and (ii) Seller
                  shall not be under any obligation whatsoever to undertake any improvement, repair,
                  modification, alteration, remediation, or other work of any kind with respect to any of the
                  Storage Assets;

         (d)      individually, and on behalf of its successors and assigns, and except as specifically provided for in,
                  and without limiting Seller's indemnity obligations contained in Section 9.02(a), hereby
                  expressly releases Seller from any and all responsibilities, liabilities, obligations, and
                  claims, known and unknown, whether based upon negligence, strict liability, or otherwise,
                  arising under Environmental Laws or any other Legal Requirement, including, without limitation,
                  any obligations to take the Storage Assets back or reduce the Purchase Price, or any actions
                  for contribution or indemnity, or to improve, repair, or otherwise modify the physical or
                  environmental condition or operation of the Storage Assets, that Buyer or its successors or
                  assigns may have against Seller or that may arise in the future, based, in whole or in part,
                  upon the presence of Hazardous Materials or other Environmental Contamination on, around,
                  within, or under the Storage Assets or arising from the environmental condition or physical
                  condition of the Storage Assets, regardless of how caused or created (by Seller's negligence,
                  actions, omissions, or fault, pursuant to any statutory scheme of strict liability, or
                  otherwise).  Buyer further acknowledges that the provisions of this Section 9.01 have been
                  fully explained to Buyer and that it fully understands and accepts the same as a condition to
                  proceeding with this transaction.  Buyer acknowledges that none of Seller's employees, agents,
                  or representatives have made any statements or representations contrary to the provisions of
                  this Section 9.01;

         (e)      except as specifically stated in this Agreement, acknowledges that Seller makes no warranty or
                  representation, express, implied, statutory or otherwise, as to the accuracy or completeness of
                  any title opinion, data, reports, records, projections, information, or materials now,
                  heretofore, or hereafter furnished or made available to Buyer in connection with the Storage
                  Assets, including, without limitation, any description of the Storage Assets, the pricing
                  assumptions, the environmental condition or physical condition of the Storage Assets, any other
                  matters contained in the data, or any other materials furnished or made available to Buyer by
                  Seller or by Seller's employees, agents, or representatives;

         (f)      recognizes and expressly acknowledges that the Storage Assets may contain asbestos coating, insulation
                  or other asbestos-containing materials (collectively, "Asbestos") and that any such asbestos
                  may be in a friable or nonfriable condition.  Seller makes no representations or warranties
                  regarding the extent or condition of any Asbestos-containing material associated with the
                  Storage Assets.  Buyer, as owner and/or operator of the Storage Assets after Closing, expressly
                  assumes all responsibility for complying with all applicable regulatory obligations relating to
                  any such Asbestos, including those arising under environmental and worker health and safety
                  laws.  Buyer hereby certifies to Seller that Buyer and its employees, contractors, and agents
                  that may come into contact with such Asbestos will comply with all applicable laws and other
                  governmental requirements relating thereto, including requirements relating to the training of
                  workers in the handling of Asbestos; and

         (g)      by virtue of the purchase of the Storage Assets from Seller, acknowledges that Seller hereby expressly
                  excludes, and does not assign, transfer, or convey to Buyer any rights or benefits of or to any
                  insurance policies of Seller or Seller's Affiliates which might relate to, cover, or insure
                  Seller for loss of or liability arising from the use, ownership, or operation of the Storage
                  Assets, regardless of whether such assignment, right, or benefit arises by statute, agreement,
                  or operation of law, including but not limited to defense and indemnity benefits attributable
                  to or arising from or under such policies.

                  parent company, Affiliates, and Subsidiaries and their respective partners, members, directors,
                  shareholders, officers, employees, agents, attorneys, representatives, contractors, and

                  and consultant fees), costs, and causes of action, including for an Environmental Liability
                  (collectively, the "Liabilities/Claims," and individually, a "Liability/Claim"), regardless of
                  whether the Liabilities/Claims were caused in whole or in part by the strict liability, fault,
                  or negligence of Buyer or any other Person (whether sole, joint, concurrent, or comparative
                  with any strict liability, fault, or negligence of Seller or any other Person) arising from or
                  relating to (i) the ownership or operation of the Storage Assets before the Effective Time or
                  any act or omission of Seller or its Affiliates before the Effective Time in connection with
                  the Storage Assets, regardless of when a claim is recognized or asserted with respect to such
                  loss; provided, that Seller owes no indemnity obligation for Liabilities/Claims arising from or
                  relating to the condition of the Storage Assets prior to the Effective Time resulting in injury
                  or damage after the Effective Time; (ii) the breach of any representation or warranty of Seller
                  contained in this Agreement; or (iii) any Excluded Liabilities; provided, however, that:

                  (A)      Seller's obligations to indemnify Buyer Indemnitees pursuant to this Section 9.02 will be limited by
                           Section 9.04;

                  (B)      Seller shall have no liability under Section 9.02(a)(i) (except to the extent provided in Section
                           9.02(a)(iii)) or Section 9.02(a)(ii) unless the aggregate of all Liabilities/Claims
                           relating thereto for which Seller would, but for this proviso, be liable exceeds, on a
                           cumulative basis, an amount equal to Five Million Dollars ($5,000,000.00);

                  (C)      Seller's aggregate liability under Section 9.02(a)(i) (excluding any liability under Section
                           9.02(a)(iii)) and Section 9.02(a)(ii) shall in no event exceed Five Million Dollars
                           ($5,000,000.00); and

                  (D)      The limitations set forth in Sections 9.02(a)(B) and (C) shall not apply to any indemnity for Taxes
                           under Article X, and indemnities for Taxes will not be taken into account in
                           determining the satisfaction of the thresholds and caps of Sections 9.02(a)(B) and (C).

         (b)      Buyer's Indemnity.  Buyer shall indemnify, reimburse, defend, and hold harmless Seller, its
                  parent companies, Affiliates, and subsidiaries and their respective partners, members,
                  directors, shareholders, officers, employees, agents, attorneys, representatives, contractors,
                  and subcontractors (collectively, the "Seller Indemnitees") from and against any and all
                  Liabilities/Claims, regardless of whether the Liabilities/Claims were caused in whole or in
                  part by the strict liability, fault, or negligence of Seller or any other Person (whether sole,
                  joint, concurrent, or comparative with any strict liability, fault, or negligence of Buyer or
                  any other person) arising from or relating to (i) the ownership or operation of the Storage

                  its Affiliates) prior to the Effective Time in connection with the Storage Assets to the extent
                  that Seller does not have an indemnification obligation as the result of Section 9.02(a)(B),


PAGE 27


                  Section 9.02(a)(C) or Section 9.04, (iv) the breach of any representations or warranty of Buyer
                  contained in this Agreement, or (v) any Assumed Liabilities.

         (c)      Sole and Exclusive Remedy.  Other than claims for actual fraud, violations of covenants to be
                  performed after the Closing and claims under other contractual relationships between the
                  Parties, the right of each Party to seek indemnification from the other Party pursuant to this
                  Article IX shall be the sole and exclusive remedy of each Party against the other with respect
                  to this Agreement or the transaction contemplated hereby.  Any adjustments to the Purchase
                  Price pursuant to Section 3.02 shall not be deemed to be payments pursuant to Section 9.02(a)
                  or Section 9.02(b).

         (d)      Limitation.  Notwithstanding anything to the contrary contained in this Article IX, no Party (i)
                  shall be liable to another Party for any damages related to or arising in connection with this
                  Agreement or the transactions contemplated hereby other than actual or compensatory damages; it
                  being agreed that no Party shall be liable for indirect, incidental, consequential (including,
                  but not limited to, lost profits or earnings, losses due to business interruption or diminution
                  in value of the Storage Assets), exemplary, or punitive damages hereunder, except to the extent
                  arising from third parties, or (ii) shall be entitled to recover more than once for any single
                  Liability/Claim for which a Party has indemnified another Party, such as in the case of a
                  single Liability/Claim resulting from the breach of more than one representation, warranty,
                  covenant, or agreement hereunder.

9.03     Survival of Representations and Warranties.  Except as set forth below in this Section 9.03 or in
         Section 9.04, all obligations under this Agreement, including the indemnification obligations hereunder,
         shall survive the Effective Time; provided, that the representations and warranties of Seller contained
         in Sections 4.01, 4.02, and 4.04 and of Buyer in Sections 5.01, 5.02, and 5.04 shall survive the
         Effective Time indefinitely, the representations and warranties of Seller contained in Section 4.13
         shall terminate at the close of business two (2) years following the Closing, the representations and
         warranties of Seller contained in Section 4.10 shall terminate upon the expiration of the applicable
         statute of limitations, and all other representations and warranties of Seller and Buyer shall survive
         the Effective Time for eighteen (18) months.  Notwithstanding the foregoing, all representations and
         warranties shall survive beyond the applicable dates specified above with respect to any claim hereunder
         for indemnification based on any misrepresentation or breach of warranty that is asserted in reasonable
         detail in writing on or prior to such date.

9.04     Termination of Indemnification.  The obligations to indemnify and hold harmless a Party hereto
         (a) pursuant to Section 10.02, shall terminate at the time the applicable statutes of limitations with
         respect to the Tax liabilities in question expire (giving effect to any extension thereof), (b) pursuant
         to Section 9.02(a)(ii) and Section 9.02(b)(iii), shall terminate when the applicable representation or
         warranty terminates pursuant to Section 9.03, (c) pursuant to Section 9.02(a)(i), shall terminate four
         (4) years after the Effective Time, and (d) pursuant to the other clauses of Section 9.02, shall not
         terminate notwithstanding any otherwise applicable statutes of limitation; provided, however, that as to
         clauses (a), (b), and (c) above, such obligations to indemnify and hold harmless shall not terminate
         with respect to any item as to which the Person to be indemnified or the related party thereto shall
         have, before the expiration of the applicable period, previously made a claim by delivering a written
         notice of such claim (stating in reasonable detail the basis of such claim) to the indemnifying party.

9.05     Title Defect Indemnity. Subject to the limitations provided for in this Article IX, Seller shall
         indemnify, reimburse, defend, and hold harmless Buyer Indemnitees from and against any and all
         Liabilities/Claims caused by Title Defects involving the Material Instruments, but only to the extent
         that such Title Defect is demonstrated to have existed before the Effective Time. Seller's liability
         under this Section 9.05 (of any kind, including for indemnity or otherwise) for any Liabilities/Claims
         which are the subject of this Section shall be limited (a) to any such Liabilities/Claims asserted
         within one (1) year after the Effective Time by a Buyer Indemnitee giving Seller written notice in
         accordance with the provisions of Section 9.06; and (b) Seller shall have no liability or obligation to
         indemnify or reimburse Buyer Indemnitee with respect to such Liabilities/Claims until such time as the


PAGE 28

         aggregate of such Liabilities/Claims exceeds Two Hundred Fifty Thousand Dollars ($250,000.00) (the
         "Title Deductible"), at which time Seller shall indemnify, reimburse, defend and hold harmless Buyer
         Indemnitee with respect to the next Two Hundred Fifty Thousand Dollars ($250,000.00) (the "Title Defect
         Cap").  The indemnity obligation under this Section 9.05 shall terminate at the earlier of (a) when
         Seller or Seller Guarantors have paid Two Hundred Fifty Thousand Dollars ($250,000.00) or (b) one (1)
         year after the Effective Time; provided, that it shall not terminate at such time with respect to any
         Title Defect (but subject to the Title Defect Cap) as to which Buyer has, before expiration of such
         one-year period, previously made a claim by delivering a written notice of such claim (stating in
         reasonable detail the basis of such claim) to Seller.

9.06     Indemnification Procedures.  In the event that any Proceedings shall be instituted or any claim
         shall be asserted by any Person in respect of which indemnification may be sought by any Party or
         Parties from any other Party or Parties under the provisions of this Agreement, the Party or Parties
         seeking indemnification (collectively, the "Indemnitee") shall cause written notice of the assertion of
         any claim of which it has knowledge that is covered by the indemnity to be forwarded promptly to the
         Party or Parties from which indemnification is sought (collectively, the "Indemnitor").  The Indemnitor
         shall have the right, at its option and at its own expense, to be represented by counsel of its choice
         and to participate in, or to take exclusive control of, the defense, negotiation, and/or settlement of
         any Proceeding or demand which relates to any amounts indemnifiable or potentially indemnifiable under
         this Agreement; provided, however, that the Indemnitee may participate in any such Proceeding with
         counsel of its choice and at its own expense.  The Indemnitor shall not have the right to admit
         liability with respect to, or compromise, settle or discharge any claim or consent to the entry of any
         judgment with respect to such claim, without the consent of the Indemnitee, which consent shall not be
         unreasonably withheld, delayed, or conditioned, unless such settlement, compromise or consent includes
         an unconditional release of the Indemnitee from all liability and obligations arising out of such
         claim.  Notwithstanding the foregoing, the Indemnitee shall have the right to pay or settle any such
         claim; provided, that in such event it shall waive any right to indemnity therefor by the Indemnitor.
         In the event that the Indemnitor elects not to defend or settle such Proceeding or demand and the
         Indemnitee defends, settles, or otherwise deals with any such Proceeding or demand, which settlement may
         be without the consent of the Indemnitor, the Indemnitee will provide fifteen (15) days advance written
         notice of any settlement to the Indemnitor and will act reasonably and in accordance with its good faith
         business judgment.  The Parties hereto agree to reasonably cooperate fully with each other in connection
         with the defense, negotiation, or settlement of any such Proceeding or demand.  After final judgment or
         award shall have been rendered by a Governmental Body and the expiration of the time in which to appeal
         therefrom, or a settlement shall have been consummated, or the Indemnitee and the Indemnitor shall have
         arrived at a mutually binding agreement with respect to each separate matter indemnified by the
         Indemnitor, the Indemnitee shall forward to the Indemnitor notice of any sums due and owing by the
         Indemnitor with respect to such matter and the Indemnitor shall pay all of the sums so owing to the
         Indemnitee by check within thirty (30) days after the date of such notice.  In the event of any claim by
         a third party against an Indemnitee, the Indemnitee will, at its own expense, use its commercially
         reasonable efforts to make available to the Indemnitor those employees whose assistance, testimony, or
         presence is necessary to assist the Indemnitor in evaluating and in defending such claims; provided,
         however, that any such access shall be conducted in such a manner as not to interfere unreasonably with
         the operations of the business of the Indemnitee but failure to provide necessary witnesses or access to
         information will excuse the Indemnitor's performance.

9.07     Compliance with Express Negligence Rule.  Disclaimers, limitations on liability and indemnities
         in this Agreement shall apply even in the event of the sole, joint and/or concurrent negligence, strict
         liability or other fault of the party whose liability is released, disclaimed, limited or indemnified.

                                   TAXES

10.01    Purchase Price Allocation(a). Seller and Buyer agree that the Purchase Price (as adjusted
         pursuant to the terms of this Agreement) and the Assumed Liabilities will be allocated among the Storage


PAGE 29


         Assets for all purposes (including tax and financial accounting purposes) as jointly agreed between
         Buyer and Seller within ninety (90) days after the Closing Date. Buyer, Seller and their applicable
         Affiliates will file all Returns in a manner consistent with such allocation.  Should, by the end of
         such 90-day period, the Parties be unable to agree on such allocation as contemplated by this Section
         10.01, the Parties' disagreement with respect thereto shall be referred to the Accounting Firm which
         shall resolve such dispute, which resolution shall be final and binding, in the manner provided for in
         Section 7.01(b) hereof.

10.02    Liability for Taxes.

         (a)      Except as otherwise provided in this Agreement, Buyer, on the one hand, and Seller and Seller Owners, on
                  the other hand, shall be liable for the Taxes imposed upon them by law and neither shall have
                  any right to indemnity from the other on account of Taxes.

         (b)      Seller shall be liable for, and shall indemnify and hold Buyer and its Affiliates harmless from, (i) any
                  Taxes caused by or resulting from the sale of the Storage Assets pursuant to this Agreement
                  (excluding the Taxes specified in Section 10.03), (ii) any Taxes relating to the income,
                  ownership, sale or other transfer of the Excluded Assets or any other assets of Seller other
                  than the Storage Assets, (iii) any Taxes imposed with respect to the ownership or operation of
                  the Storage Assets for any taxable period ending on or before the Effective Time (or the
                  portion, determined as described in paragraph (d) of this Section 10.02, of any such Taxes for
                  any taxable period beginning on or before and ending after the Effective Time which is
                  allocable to the portion of such period prior to the Effective Time (the "Pre-Closing
                  Period")), (iv) any Taxes arising from a breach of Seller's representations pursuant to Section
                  4.10 (treating such representations as made as of the date hereof and as of the Closing Date),
                  (v) the real and personal property taxes contemplated by Section 3.02(a)(ii), and (vi) any
                  attorneys' fees or other costs incurred by Buyer or any of its Affiliates in connection with
                  any payment from Seller under this Section 10.02(b).

         (c)      Buyer shall be liable for, and shall indemnify and hold Seller and its Affiliates harmless from, (i) any
                  Taxes (including the Taxes specified in Section 10.03) imposed with respect to the Storage
                  Assets for which Seller is not liable pursuant to Section 10.02(b), and (ii) any attorneys'
                  fees or other costs incurred by Seller and its Affiliates in connection with any payment from
                  Buyer under this Section 10.02(c).

         (d)      Whenever it is necessary for the purposes of Section 10.02(b)(iii) or Section 10.02(c)(i) to determine
                  the portion of any Taxes imposed on or for a taxable period beginning on or before and ending
                  after the Effective Time which is allocable to the Pre-Closing Period, the determination shall
                  be made, in the case of property, ad valorem or similar Taxes (which are not measured by, or
                  based upon, production) or franchise or capital Taxes (which are not measured by, or based
                  upon, net income), on a per diem basis, and, in the case of other Taxes, by assuming that the
                  Pre-Closing Period constitutes a separate taxable period and by taking into account the actual
                  taxable events occurring during such period (except that exemptions, allowances and deductions
                  for a taxable period beginning on or before and ending after the Effective Time that are
                  calculated on an annual or periodic basis shall be apportioned to the Pre-Closing Period
                  ratably on a per diem basis.

         (e)      Buyer agrees to pay to Seller any refund received after the Effective Time by Buyer or its Affiliates,
                  including the Seller Transferred Subsidiaries, in respect of any Taxes for which Seller is
                  liable under Section 10.02(b).  Seller agrees to pay to Buyer any refund received by Seller or
                  its Affiliates in respect of any Taxes for which Buyer is liable under Section 10.02(c).  The
                  Parties shall cooperate in order to take all necessary steps to claim any such refund. Any such
                  refund received by a Party or its Affiliate for the account of the other Party shall be paid to
                  such other Party within thirty (30) days after such refund is received.

         (f)      The adjustment to the Purchase Price for certain property Taxes pursuant to Section 3.02(a)(ii) of this
                  Agreement shall constitute a preliminary settlement of the indemnity obligations under this
                  Section 10.02 relating to such Taxes.  Further adjustments shall be made, pursuant to the


PAGE 30


                  provisions of this Article X, to the extent those Taxes differ from the amounts used in
                  calculating the adjustment to the Purchase Price.

10.03    Transfer Taxes.  Buyer agrees to be liable for any and all conveyance, transfer, recording and
         registration fees and sales, use, gross receipts, motor vehicle transfer and excise, real estate
         transfer, documentary stamp and similar transfer Taxes imposed with respect to the sale, conveyance and
         assignment of the Storage Assets hereunder.   Buyer shall prepare and file, to the extent permitted by
         law, any necessary Returns in connection with the foregoing Taxes and fees to be borne by Buyer and pay
         all filing and recording fees relating to the filing and recording of any instruments delivered by Buyer
         to convey the Storage Assets to Buyer.  Seller shall cooperate with the Buyer to establish and document
         all exemptions from such taxes and fees for which the sale, conveyance and assignment of the Storage
         Assets is eligible.

10.04    Tax Proceedings.  In the event Buyer or any of its Affiliates receive notice (the "Proceeding
         Notice") of any examination, claim, adjustment or other Proceeding with respect to the liability of the
         Buyer for Taxes for which Seller is or may be liable under Section 10.02(b), Buyer shall notify Seller
         in writing thereof (the "Buyer Notice") no later than seven (7) business days after the receipt by Buyer
         or any of its Affiliates of the Proceeding Notice.  As to any such Taxes for which Seller is or may be
         liable under Section 10.02(b), Seller shall be entitled at its expense to control or settle the contest
         of such examination, claim, adjustment or other Proceeding, provided Seller notifies Buyer in writing
         that Seller desires to do so no later than the earlier of (i) thirty (30) days after receipt of the
         Buyer Notice or (ii) five (5) days prior to the deadline for responding to the Proceeding Notice.  The
         Parties shall cooperate with each other and with their respective Affiliates, and will consult with each
         other, in the negotiation and settlement of any Proceeding described in this Section 10.04.

10.05    Payment of Taxes.  Except as provided in Section 3.02(a)(ii) and Section 10.02, all Taxes shall
         be paid by the Party that is legally responsible therefor. Any amount to which a Party is entitled under
         this Article X shall be promptly paid to such Party by the Party obligated to make such payment
         following written notice to the Party so obligated stating that the Taxes to which such amount relates
         are due and providing details supporting the calculation of such amount.

10.06    Tax Returns.  Except as provided in Section 10.03, all Returns relating to the Storage Assets
         shall be prepared and filed by the Party that is legally responsible therefor. Each Party shall
         cooperate with the other Party and shall make available all necessary records and timely take all action
         necessary to allow the other Party to prepare and file the Returns relating to the Storage Assets which
         such Party is responsible for preparing and filing under this Section 10.06.  Buyer agrees that its 2002
         Returns relating to the Storage Assets shall cover all periods beginning as of the Effective Time.
         Seller agrees that its 2002 Returns relating to the Storage Assets will not cover any periods after the
         Effective Time.

10.07    Cooperation and Exchange of Information.  Each Party will provide, or cause to be provided, to
         the other Party copies of all correspondence received from any Governmental Body by such Party or any of
         its Affiliates in connection with any Taxes for which such other Party is or may be liable under Section
         10.02(b) or Section 10.02(c).  The Parties will provide each other with such cooperation and information
         as they may reasonably request of each other in preparing or filing any Return or claim for refund, in
         determining a liability or a right of refund or in conducting any audit or other Proceeding in respect
         of Taxes imposed on the Parties or their respective Affiliates. The Parties and their Affiliates will
         preserve and retain all Returns, schedules, work papers and all material records or other documents
         relating to any such Returns, claims, audits or other proceedings until the expiration of the statutory
         period of limitations (including extensions) of taxable periods to which such documents relate and until
         the final determination of any payments which may be required with respect to such periods under this
         Agreement and shall make such documents available to the other Party or any Affiliate thereof, and their
         respective officers, employees and agents, upon reasonable notice and at reasonable times, it being
         understood that such representatives shall be entitled to make copies of any such books and records
         relating to the Storage Assets as they shall deem necessary. Any information obtained pursuant to this
         Section 10.07 shall be kept confidential, except as may be otherwise necessary in connection with the
         filing of Returns or claims for refund or in conducting any audit or other Proceeding. Each Party shall

         provisions of this Agreement, the provisions of this Article X shall control.

                                   ARTICLE XI
                             EMPLOYEE MATTERS

11.01    Employees.

         (a)      Buyer may interview and offer employment to any or all of the individuals listed on Schedule 11.01 (the
                  "Employees"), which offers of employment shall be effective as of 12:00:01 a.m. on February 1,
                  2002 (the "Employment Effective Time"). Buyer shall provide to Seller a list of all of those
                  Employees it wishes to interview or to make offers of employment without interviews and shall
                  coordinate interviews with a Seller-designated representative.  Seller shall (i) cooperate with
                  Buyer in its attempts to hire such Employees who may be offered employment by Buyer, (ii)
                  permit Buyer to review the personnel records and such other information concerning such
                  Employees as Buyer may reasonably request, subject to obtaining any legally required written
                  permission of any affected Employee and subject to any restrictions imposed by applicable law,
                  and (iii) not directly or indirectly discourage any Employee from accepting an offer of
                  employment from Buyer.   Buyer shall provide to Seller a list of those Employees it intends to
                  make offers of employment, which list shall include the offered salary and location of
                  employment.  Seller shall, and shall cause its owners and its Affiliates to, continue to employ
                  all Employees through the Employment Effective Time, except for any Employee who (i) is
                  terminated with the prior written consent of Buyer or (ii) voluntarily resigns. Buyer shall
                  also provide to Seller a list of those Employees who have previously accepted Buyer's
                  employment offer on the Closing Date. Those Employees accepting employment with Buyer effective
                  as of the Employment Effective Date are herein referred to as the "Hired Employees."  Buyer
                  agrees that it will treat the Hired Employees on substantially the same basis as other
                  similarly situated employees of Buyer.  Seller shall not, and shall cause its owners and their
                  respective Affiliates to not, solicit the services of any Hired Employee during the one-year
                  period following the Closing Date.

         (b)      Buyer will be responsible for any severance pay and severance benefits to the extent required under
                  federal, state, or local law, or notices required under such laws, with respect to terminations
                  by Buyer of Hired Employees occurring after the Employment Effective Time.  Buyer shall defend,
                  indemnify, and hold Seller and its Affiliates harmless from any Liabilities/Claims by any Hired
                  Employee for their wages, salaries, bonuses, severance pay, and severance benefits provided
                  under federal, state, or local law, notices required under such laws, and compensation or
                  benefits of any kind which accrue under Buyer's employee benefit plans as a result of and
                  related to any of the Hired Employees' employment by Buyer after the Employment Effective Time.

         (c)      Seller or its Affiliates shall retain responsibility for payment of the following matters that accrue
                  for the periods prior to and through the Employment Effective Time as a result of the
                  Employees' employment with Seller:

                  (i)      wages, salaries and bonuses;

                  (ii)     severance pay and severance benefits to the extent required under federal, state, or local law, or
                           notices required under such laws, with respect to employees of Seller (including,
                           without limitation, the Hired Employees) who are terminated by Seller or an Affiliate
                           of Seller on or prior to the Employment Effective Time; and


PAGE 32


                  (iii)    except as otherwise expressly provided in this Article XI, all liability and obligations under all
                           Employee Benefit Plans, deferred and incentive compensation plans of Seller or its
                           Affiliates and all employment-based or related claims and matters.

                           Notwithstanding the foregoing in this Section 11.01(c) and except as already accounted
                           for as part of the Net Operating Cash Flow or Net Operating Cash Deficit under Section
                           7.06, Buyer shall, or shall cause one or more of Buyer's Affiliates to, reimburse
                           Seller and/or Seller's Affiliates, as the case may be, for the  actual costs and
                           expenses described in Sections 11.01(c)(i) and 11.01(c)(iii) and incurred and paid by
                           Seller and/or Seller's Affiliates to the Hired Employees during the period beginning
                           on and including January 1, 2002, and ending on and including January 31, 2002 (the
                           "Reimbursed Employee Expenses"), such reimbursement to be paid by Buyer and/or Buyer's
                           Affiliates to Seller and/or Seller's Affiliates, as the case may be, within ten (10)
                           Business Days following the date on which Buyer shall have received from Seller a
                           certificate certifying the Reimbursed Employee Expenses and containing, in reasonable
                           detail, the basis and method of the calculation thereof.

11.02    Employee Benefit Plans.

         (a)      As of the Employment Effective Time, Seller or its Affiliates shall cause the termination of the
                  participation of the Hired Employees in all of the savings, Code section 401(k), pension,
                  retirement, medical, dental, life insurance, accident and sickness, short-term disability,
                  long-term disability, profit-sharing, deferred compensation, stock option, vacation, stock
                  bonus, employee stock ownership, bonus, severance, or other similar plans, programs,
                  agreements, and arrangements, including all employee benefit plans as defined in Section 3(3)
                  of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), which are
                  maintained by or contributed to by Seller (the "Plans"), except that the Hired Employees'
                  participation in Seller's or its Affiliates' medical and dental plans shall continue through
                  the last day of the month prior to the Employment Effective Time.  At the end of the last day
                  of the month priot to the Employment Effective Time, the Hired Employees' participation in
                  Seller's or its Affiliates' medical and dental plans shall terminate. Seller and Buyer shall
                  mutually determine and agree as to whether the "same desk" rule applies to the Seller's or its
                  Affiliates' tax qualified savings plan.  If such rule does not apply, Seller shall make
                  distribution to the Employees in accordance with the terms of Seller's or its Affiliates'
                  plan.  Seller and Buyer shall permit direct rollovers to Buyer's plan in cash and participation
                  notes for electing participants.  If such rule applies, the Parties shall cooperate in
                  determining whether a Plan to Plan transfer of assets from Seller's or its Affiliates' tax
                  qualified savings plan to Buyer's tax qualified savings plan can be made for the Hired
                  Employees.  If it is determined a transfer of assets can be made, the Parties shall promptly
                  arrange a conference call with their respective record keepers of their Plans and direct the
                  record keepers to cause a transfer of assets ("TOA"), in a form acceptable to Buyer, and shall
                  establish a date for the TOA. The Parties shall urge their respective record keepers to
                  conclude the TOA as quickly as possible, but in any event within nine (9) months after the
                  Parties have agreed to the TOA. Each Party shall ensure that amendments to its Plan documents
                  necessary to accomplish the TOA are submitted to its board of directors prior to the TOA and
                  shall provide the other Party with a copy of any such amendment upon adoption.

         (b)      All of the Hired Employees will be permitted to enroll in all of Buyer's Plans upon the termination of
                  such benefits under Seller's or its Affiliates' Plans and any other benefit plan of Buyer in
                  accordance with the terms and conditions of Buyer's plans in effect from time to time for its
                  similarly situated employees generally.

         (c)      After the Employment Effective Time, Buyer shall waive or cause the waiver of waiting periods,
                  pre-existing condition exclusions, and other limitations on participation otherwise applicable
                  to any Hired Employee and qualified dependents (who was covered by an employee group health
                  plan of Seller or its Affiliates and immediately elects to be covered by the group health plan
                  of Buyer) under or with respect to all plans maintained by Buyer for such Hired Employees.


PAGE 33


                  Buyer shall recognize or cause to be recognized all claims and expenses of Hired Employees
                  during 2001 for purposes of satisfying applicable deductible provisions (and any other like
                  adjustments or limitations on coverage) under, and to the extent recognized for current
                  employees of Buyer, all applicable group health plans maintained by Buyer.  Seller shall cause
                  Seller's or its Affiliates' plan providers and insurers to provide to Buyer a true and complete
                  listing of all amounts so expended (including co-payments and deductibles paid) with respect to
                  each Hired Employee and such other information as Buyer may reasonably require in order to
                  properly administer the provisions of this Section 11.02(c).

         (d)      Without limiting Section 11.01(c)(iii), Seller shall retain responsibility for all medical, dental,
                  life, vision, AD and D, cafeteria, short-term disability, and long-term disability claims by any
                  Hired Employee which were incurred on or prior to the Employment Effective Time and for
                  workers' compensation claims related to injuries arising from the employment of the Employees
                  for periods prior to and through the Employment Effective Time, in each case to the extent
                  covered by the respective employee benefit plan and/or insurance plan or policy of Seller or
                  its Affiliates, and any claims regarding Seller's 401(k) Plan which arise out of the
                  administration or operation of such Plan prior to the Employment Effective Time.  Seller will
                  provide reasonable assistance, at no cost to Buyer, for the administration or termination of
                  such benefits.

         (e)      For purposes of this Section 11.02, a claim for reimbursement under a medical, hospital or dental,
                  prescription drug, or similar plan shall be deemed to be incurred on the date that the claim
                  occurs.  A claim occurs on the date service is provided and there shall be no continuation of a
                  claim from one day to the next.  In the event of a hospitalization commencing on or prior to
                  the last day of the month prior to the month in which the Employment Effective Time occurs, any
                  existing coverage shall cease on the end of the last day of the month prior to the month in
                  which the Employment Effective Time occurs unless the participant elects COBRA continuation
                  coverage.

         (f)      To the extent recognized by Seller, prior employment with Seller or an Affiliate thereof shall be
                  recognized by Buyer for the purpose of determining service awards, vacation eligibility, and
                  for eligibility, vesting, and participation under Buyer's employee benefit plans for the Hired
                  Employees but not with respect to calculating pension benefit payments; provided, however, that
                  vacation time accrued and unused while a Hired Employee was employed by Seller's Affiliate
                  shall be paid by the employing Affiliate to the applicable Hired Employees; and provided
                  further, that Buyer shall allow Hired Employees to take such accrued and unused vacation on or
                  before the time it would have been required to be taken under the Hired Employee's prior
                  employer's policies without pay. Neither the foregoing nor any other provision of this Article
                  XI constitutes an assumption of any liability by Buyer with respect to any liability or
                  obligation of Seller, its owners or an Affiliate thereof to or with respect to any Hired
                  Employees.  Commencing with the anniversary year of their employment with Buyer, Hired
                  Employees will be given vacation recognizing prior years of service with Seller or its
                  Affiliates on Buyer's vacation schedule.

         (g)      Seller shall not include a reserve for accrued bonuses through the Employment Effective Time.  Seller
                  shall pay such amounts directly to the Hired Employees on the date of termination of employment
                  with Seller, its owners or their respective Affiliates, as the case may be.

         (h)      Seller shall cause each Hired Employee to be one hundred percent (100%) vested in his or her accrued
                  benefits under each employee benefit plan of Seller and its Affiliates as of the Employment
                  Effective Time.

         (i)      Nothing in this Article XI should be construed as requiring Buyer to maintain any employee benefit plan
                  or prevent Buyer from amending or terminating any employee benefit plan at any time in its sole
                  discretion.  Further, nothing herein shall prevent Buyer from terminating any Hired Employee
                  after the Employment Effective Time for any reason.

         (j)      No provision of this Article XI shall create any third-party beneficiary rights in any Hired Employee
                  (or any beneficiary or dependent thereof), including without limitation, any right to continued


PAGE 34


                  employment with Buyer for any specified period of time after the Employment Effective Time.

         (k)      Seller and Buyer agree that, with respect to Hired Employees who accept employment with Buyer upon the
                  Closing, each will take the position that they respectively meet the definitions of
                  "predecessor" and "successor" as defined in Revenue Procedure 96-60 and IRS Regulation Section
                  31.3121(a)(1)-1(b).  Absent a mutual agreement to the contrary, Seller and Buyer will use the
                  "Standard Procedure" described in Section 4 of Revenue Procedure 96-60.  Seller shall supply to
                  Buyer, with respect to all Hired Employees, all cumulative payroll information as of the
                  Employment Effective Time that Buyer shall reasonably request in order to comply with IRS
                  Regulation 31.3121(a)(1)-1(b).

                                  ARTICLE XII
                         MISCELLANEOUS PROVISIONS

12.01    Commission.  Each of the Parties hereto represents and warrants that there are no claims for
         brokerage commission or finders' fees in connection with the transaction contemplated by this Agreement,
         and Seller and Buyer will respectively pay or discharge, and will defend (upon the other's request) and
         indemnify the other for, brokerage commissions or finders' fees incurred by reason of any action taken
         by such indemnifying party.

12.02    Assignment. The terms, provisions, and conditions of this Agreement shall extend to, be binding
         upon, and inure to the benefit of the Parties hereto, their respective successors, and assigns.  No
         Party will make an assignment of its rights and/or obligations under this Agreement to a Person that is
         not an Affiliate of such assigning Party without the prior written consent of the other, which such
         consent may be withheld for any reason; provided, that the assigning Party, as a condition to making an
         assignment to an Affiliate or to obtaining the consent of the other Party to any non-Affiliate
         assignment, shall execute and deliver an instrument, in a form reasonably satisfactory to the consenting
         Party, by which the assigning party expressly agrees to remain bound by and primarily liable under this
         Agreement.  Any assignment or attempted assignment in violation of the foregoing shall be void.

12.03    Entire Agreement; Amendments.  This Agreement and the Exhibits and Schedules attached hereto and
         incorporated by reference herein contain the entire understanding of the Parties with respect to its
         subject matter.  There are no restrictions, agreements, promises, warranties, covenants, or undertakings
         relating to the transactions contemplated herein other than those expressly set forth herein.  This
         Agreement supersedes all prior agreements and understandings between the Parties with respect to its
         subject matter, except for that certain Confidentiality Agreement dated December 14, 2000, between the
         Parties or their Affiliates which shall remain in full force and effect pursuant to its terms until the
         Closing, and shall further remain in full force and effect with respect to all information provided to
         Buyer or its Affiliates with respect to any of Seller's or its Affiliate's businesses or assets other
         than the Storage Assets. This Agreement may be amended only by a written instrument duly executed by the
         Parties.  Any condition to a Party's obligations hereunder may be waived in writing by such Party.  No
         waiver by any Party of any one or more defaults by the other in performance of any of the provisions of
         this Agreement shall operate or be construed as a waiver of any future default or defaults, whether of a
         like or different character.

12.04    Severability.  Each portion of this Agreement is intended to be severable.  If any term or
         provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall
         not affect the validity of the remainder of this Agreement.

12.05    Actions.  Seller and Buyer, singularly and plurally, warrant and agree that each shall use its
         commercially reasonable efforts to take or cause to be taken all such action as may be necessary to
         consummate and make effective the transaction as set forth in this Agreement and to assure that it will
         not be under any material corporate, legal, or contractual restriction that would prohibit or delay the
         timely consummation of such transaction.


PAGE 35


12.06    Termination.

         (a)      This Agreement may be terminated at any time on or prior to the Closing:

                  (i)      by mutual written consent of Seller and Buyer;

                  (ii)     by Seller on the Closing if the conditions set forth in Section 8.03 have not been satisfied in all
                           material respects by Buyer or have not been waived by Seller in writing by the Closing;

                  (iii)    by Buyer on the Closing if the conditions set forth in Section 8.02 have not been satisfied in all
                           material respects or have not been waived by Buyer or Seller, as appropriate, in
                           writing by the Closing;

                  (iv)     by either Party, if there shall be any order, writ, injunction or decree of any Governmental Body
                           binding Seller or Buyer which prohibits or restrains Seller or Buyer from consummating
                           the transactions contemplated hereby; or

                  (v)      by either Party in accordance with the terms of Section 6.01.

         (b)      If the Closing does not occur as a result of either Seller or Buyer exercising its right to terminate
                  pursuant to this Section 12.06, then this Agreement shall be null and void, and no Party shall
                  have any rights or obligations under this Agreement, except that:

                  (i)      All filings, applications and other submissions made to any Governmental Body shall, to the extent
                           practicable, be withdrawn from the Governmental Body to which they were made;

                  (ii)     A termination shall not relieve any Party from any liability for breach hereof, and the non-breaching
                           Party shall be entitled to any and all relief under applicable law or in equity on
                           account of such breach; and

                  (iii)    Buyer's obligations under the Confidentiality Agreement referenced in Section 12.03 shall survive any
                           such termination.

12.07    Counterparts.  This Agreement may be executed simultaneously in any number of counterparts, each
         of which shall be deemed an original, but all of which together shall constitute one and the same
         instrument.

12.08    Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY, ENFORCED IN ACCORDANCE WITH, AND INTERPRETED
         UNDER THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO ITS CONFLICTS OF LAW PRINCIPLES.

12.09    Preparation of Agreement/Relationship of Parties.  This Agreement was prepared jointly by the
         Parties hereto and not by either to the exclusion of the other.  Neither Party hereto stands in any
         fiduciary or confidential relationship to the other Party, nor are the Parties hereto partners, joint
         venturers, or otherwise in a relationship imposing any legal or equitable duty on one Party to the other
         Party.  Each Party acknowledges and agrees that it has a duty to read this Agreement and all Exhibits
         and Schedules attached hereto, and all documents and instruments referred to herein or in such Exhibits
         and Schedules; that it has in fact read this Agreement and is fully informed and has full notice and
         knowledge of its terms, conditions, and effect; that it has been represented by legal counsel of its
         choice throughout the negotiations preceding its execution of this Agreement and has received the advice
         of such counsel in connection therewith; and that it recognizes that certain of the terms of this
         Agreement provide for the assumption by one Party of, and/or release of the other Party from, certain
         liabilities that such Party would otherwise be responsible for under law.  Each Party hereby agrees that


PAGE 36


         it will not contest the validity or enforceability of any provisions of this Agreement on the basis that
         the Party had no notice or knowledge thereof or that such provisions are not "conspicuous."

12.10    No Third Party Beneficiaries.  Nothing in this Agreement shall provide any benefit to any
         third party or entitle any third party to any claim, cause of action, remedy, or right of any kind, it
         being the intent of the Parties that this Agreement shall not be construed as a third party beneficiary
         contract; provided, however, that the indemnification provisions of Article IX shall inure to the
         benefit of the Buyer Indemnitees and the Seller Indemnitees as provided therein.

12.11    Notices and Addresses.

         (a)      All notices required or permitted hereunder shall be in writing and shall be served on the Parties at
                  the addresses set forth in Section 12.11(b).  Any such notices may be sent by (i) a nationally
                  recognized overnight courier, in which case notice shall be deemed delivered three (3) business
                  days after deposit with such courier, (ii) facsimile transmission, in which case notice shall
                  be deemed delivered upon actual receipt by recipient, (iii) hand delivery, in which case notice
                  shall be deemed delivered upon actual receipt by recipient, or (iv) certified mail,
                  return-receipt requested, in which case notice will be deemed delivered three (3) business days
                  after mailing.  Copies of notices are for informational purposes only, and a failure to give or
                  receive copies of any notice shall not be deemed a failure to give notice. Any notice or other
                  communication required to be given under this Agreement or in connection with the matters
                  contemplated by it shall be in writing in the English language. The refusal to accept delivery
                  shall constitute acceptance, and in such event, the date of delivery shall be the date on which
                  delivery was refused. Notwithstanding anything to the contrary contained herein, in the event
                  that the delivery of any notice, item, or information, pursuant to the terms hereof, begins the
                  running of a time period during which a Party is obligated to respond or else have its approval
                  deemed to have been granted or denied, then such notice, item, or information shall either bear
                  or be accompanied by a cover letter which bears the following legend (in bold and capital
                  letters): "TIME SENSITIVE REQUEST - RESPONSE REQUIRED WITHIN A FINITE NUMBER OF DAYS."

12.12    Dispute Resolution.

         (a)      This Agreement is made in Texas and shall be governed by Texas law pursuant to Section 12.08.  In
                  relation to any dispute resolution, legal action, or proceedings to enforce this Agreement or
                  arising out of or in connection with this Agreement (the "Enforcement Proceedings"), each of
                  the Parties irrevocably agrees to conduct such proceedings in an appropriate federal or state
                  court sitting in Houston, Harris County, Texas, and submits to the exclusive jurisdiction of
                  such courts and waives any objection to Enforcement Proceedings in such courts on the grounds
                  of jurisdiction, venue, or on the grounds that the Enforcement Proceedings have been brought in
                  an inconvenient forum.

         (b)      The Parties agree that all claims, controversies, and disputes arising out of or relating to this
                  Agreement, or to the breach, termination, interpretation, or validity thereof (the "Disputes")
                  shall be handled as follows: The Party initiating the Dispute shall first give notice of the
                  Dispute to the other Party.  Executives (of each Party) having authority to settle the Dispute
                  shall then meet and negotiate to resolve the Dispute. If such executives fail to meet or are
                  unable to resolve the Dispute within thirty (30) days after the notice from the Party
                  initiating the Dispute, the Parties shall endeavor to settle the dispute by mediation under the
                  Mediation Procedure of the CPR Institute for Dispute Resolution ("CPR") in effect on the date
                  of this Agreement. The Parties have agreed that CPR shall select a mediator in any such
                  Dispute, and such person will agree to serve in that capacity and to be available on reasonable
                  notice. If the foregoing selected individual becomes unwilling or unable to serve, CPR shall
                  appoint another mediator. If neither of these two selected individuals is able or willing to
                  serve, the Parties will agree on a substitute with the assistance of CPR. Unless otherwise
                  agreed in writing, the Parties will select a mediator from the CPR Panels of Distinguished
                  Neutrals. Each Party agrees to bear fifty percent (50%) of CPR's mediation charges, including
                  the fees and expenses of the mediator. Other costs of the mediation will be borne by the Party
                  incurring such costs.  If the Dispute has not been resolved by mediation within sixty (60) days


PAGE 38

                  after the mediator has commenced such mediation, either Party shall be free to file an
                  appropriate action in the courts identified in the prior subsection with respect to such
                  Dispute.

         (c)      Notwithstanding the foregoing, a Party shall be free to seek judicial relief in the courts specified in
                  subsection (a) above, without resort to the dispute resolution procedures of subsection (b)
                  above, if necessary to prevent immediate or irreparable harm.

12.13    Expenses.  Whether or not the transactions contemplated hereby are consummated, and except as
         otherwise specifically provided in this Agreement, all costs and expenses incurred in connection with
         this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such costs
         or expenses.

         IN WITNESS WHEREOF, the Parties have hereto set their hands by their duly authorized officials as of the
date set forth above.

                                Enterprise Completes Acquisition of Diamond-Koch's
                                         Propylene Fractionation Business

         Houston, Texas - (February 4, 2002) - Enterprise Products Partners L.P. (NYSE:  "EPD") announced that
its operating partnership has completed the acquisition of a propylene fractionation business from D-K Diamond
Koch, L.L.C., Diamond-Koch, L.P. and Diamond-Koch III, L.P., which are jointly owned by affiliates of Valero
Energy Corporation (NYSE: "VLO") and Koch Industries, Inc.  The purchase price was $231.5 million in cash.  The
effective date of the purchase was February 1, 2002.

         This propylene fractionation business includes a 66.66 percent equity interest in a polymer-grade
propylene fractionation facility in Mont Belvieu, Texas; a 50 percent equity interest in a polymer-grade
propylene export terminal located on the Houston Ship Channel; and equity interests in four pipelines which
distribute product to customers and to the export terminal.  The fractionation plant has the capacity to produce
approximately 3 billion pounds per year, or 45,000 barrels per day, of polymer-grade propylene.

         "It is my pleasure to announce the completion of our acquisition of Diamond-Koch's propylene
fractionation business," stated O.S. "Dub" Andras, president and chief executive officer of Enterprise.  "These
are outstanding facilities.  They significantly expand our capabilities to provide fractionation, pipeline,
distribution, export terminalling and storage services to producers and consumers of all grades of propylene on
the U.S. Gulf Coast.  With the addition of these assets, we have effectively doubled Enterprise's net capacity to
produce polymer-grade propylene."

         "We have been in the business of providing polymer-grade propylene fractionation and logistic services
to the petrochemical industry since 1978.  It has a demonstrated history of steady growth and we believe has
excellent growth prospects for the future.  This acquisition should provide annualized cash accretion to our
partners of approximately $0.14 per unit on a fully diluted basis.  Together, with the acquisition of
Diamond-Koch's storage business and the start-up of recently completed pipeline projects, we have made investments
which should provide total annualized cash accretion of approximately $0.38 per partner unit." said Andras.

         Enterprise Products Partners L.P. is the second largest publicly traded, midstream energy partnership
with an enterprise value of approximately $5.5 billion.  Enterprise is a leading provider of midstream energy
services to producers and consumers of natural gas and natural gas liquids ("NGLs").  The Company's services
include natural gas transportation, processing and storage and NGL fractionation (or separation), transportation,
storage and import/export terminalling.  The Company's assets are geographically focused on the United States'
Gulf Coast, which accounts for approximately 55 percent of both domestic natural gas and NGL production and 75
percent of domestic NGL demand.

         This  press  release  includes  forward-looking  statements  within  the  meaning  of  Section  21E of the
Securities  Exchange  Act of 1934  based on the  beliefs  of the  company,  as well as  assumptions  made  by,  and
information  currently available to, management.  Although  Enterprise believes that the expectations  reflected in
such  forward-looking  statements are reasonable,  it can give no assurance that such expectations will prove to be
correct.

                  corporation ("OTC"), being fifty percent (50%) of the issued and outstanding shares of capital
                  stock of OTC (the "OTC Shares").

         (l)      The "Net Inventory," which is the refinery grade propylene ("RGP") and polymer grade propylene
                  ("PGP") owned by D-K I and D-K III as inventory, work in progress and linefill, less net
                  exchange balances (calculated separately for PGP and RGP).  However, Buyer will not be
                  obligated to purchase volumes of Net Inventory in excess of the volumes listed in Section
                  3.02(a)(3), as shown by D-K I's and D-K III's inventory records at the time of Closing, it
                  being agreed that volume in excess of said amounts ("Excess Volumes") will not be sold to Buyer
                  unless otherwise mutually agreed, and it being further agreed that Buyer shall hold such Excess
                  Volumes on exchange in Mont Belvieu for Sellers for up to one (1) month after the Effective
                  Time and will exchange such Excess Volumes back to Sellers or their designees within such one
                  (1) month period upon request by Sellers.  In addition, Buyer will, within a reasonable time
                  after request by Sellers, transport such Excess Volumes to any delivery point connected to the
                  La Porte Pipeline or the Splitter Distribution Pipelines as requested by Sellers.  If Buyer
                  holds such Excess Volumes beyond the above-referenced one (1) month period, Sellers shall pay
                  Buyer a holdover fee of ten cents (10(cent)) per barrel per month on each barrel so held.
                  Notwithstanding the foregoing, if the Net Inventory is negative for PGP or RGP, as applicable,
                  Buyer will purchase no inventory of that product.  In such event, Sellers will be obligated to
                  deliver to Buyer to Buyer's storage account at the Enterprise Products Texas Operating L.P.
                  Mont Belvieu storage facility formerly known as the Diamond-Koch East Facility a volume of PGP
                  or RGP, as applicable, sufficient to satisfy any negative Net Inventory within ten (10)
                  Business Days after the Closing Date.  Buyer will be responsible for satisfying any exchange
                  obligations to third Persons.

                  that the non-exclusive license granted hereunder limits Buyer to use of the Proprietary
                  Intellectual Property Interests to use in its own business, and Buyer is prohibited from any
                  assignment, subletting, re-licensing, or other development of the same, except in connection
                  with Buyer's sale or other disposition of the Splitter Assets made subject to the limitations
                  herein.

                                                    ARTICLE III
                                               PURCHASE PRICE

         3.01     Purchase Price.  Subject to the terms and conditions of this Agreement, and in full
payment for the Splitter Assets, Buyer shall pay to Sellers at Closing, by wire transfer as described in Section
8.01(b), the sum of Two Hundred Thirty-One Million Five Hundred Thousand Dollars ($231,500,000.00), as such sum
may be adjusted pursuant to the provisions of this Agreement (the "Purchase Price").

         3.02     Adjustments to the Purchase Price.

         (a)      Subject to final adjustment pursuant to the provisions of Article VII, the Purchase Price shall
                  initially be adjusted at Closing as follows.

                  (1)      Prepaid Expenses.  The Purchase Price will be (A) increased to reflect the
                  total prepaid items and expenses identified on Schedule 3.02(a)(1) to the extent such items and
                  expenses are paid prior to the Effective Time which inure to the benefit of the Splitter Assets
                  after the Effective Time and (B) decreased to reflect amounts and expenses identified on
                  Schedule 3.02(a)(1) paid after the Effective Time which inure to the benefit of the Splitter
                  Assets before the Effective Time.

                  (2)      Prorations.  Real estate and personal property taxes for the calendar year
                  January 1, 2002 through December 31, 2002, shall be prorated to the Effective Time based upon
                  the amounts of real estate and personal property taxes allocated to the Splitter Assets from
                  the most recent property tax assessments if known, or upon the amounts paid during the
                  preceding year to the extent not known, all as shown on Schedule 3.02(a)(2).  Such prorations
                  shall be made at Closing by an adjustment to the Purchase Price.  Buyer will assume
                  responsibility for the actual payment to the applicable Governmental Body of any unpaid
                  property taxes not yet due and which relate to periods after the Effective Time.   Buyer shall
                  defend (upon Sellers' request), indemnify, and hold Sellers harmless for any and all real
                  estate and personal property taxes and other fees and costs to be paid by Buyer in accordance
                  with this Subsection.  Sellers shall remain liable for unpaid property taxes to the extent they
                  relate to periods ending on or before December 31, 2001 and for which there has not been a
                  reduction in the Purchase Price pursuant to this Section 3.02(a)(2).

                  (3)      Inventory.  The Parties agree that the Net Inventory shown by Sellers'
                  inventory records as of the Effective Time will provide the initial basis at Closing for
                  adjusting the Purchase Price for Net Inventory (provided, that such volume does not exceed, for
                  RGP, a volume of 225,000 barrels, and for PGP, a volume of 35 million pounds). The Purchase
                  Price will be increased by the sum of the following:  (A) the product of the pounds of
                  propylene contained in the RGP in the Net Inventory multiplied by the average of the "RG
                  Propylene Spot" prices per pound reflected in the table entitled "North America Product Prices"
                  as published in the CMAI Monomer's Market Report dated January 31, 2002; (B) the product of the
                  number of gallons of the propane component in the RGP in the Net Inventory multiplied by the
                  average of the mean non-TET prices for propane for Mont Belvieu as published by the Oil Price
                  Information Service for the month of January, 2002; and (C) the product of the pounds of PGP
                  contained in the Net Inventory multiplied by the average of the "PG Propylene Spot" prices per
                  pound reflected in the table entitled "North America Product Prices" as published in the CMAI
                  Monomer's Market Report dated January 31, 2002.

         (b)      Closing Statement.  Not later than three (3) days before Closing, Sellers shall prepare and
                  deliver to Buyer a reasonable, good faith statement of the estimated Purchase Price adjustments
                  (and estimated Net Inventory figures) to be made at Closing pursuant to this Agreement (the
                  "Closing Statement").  The Parties agree that where actual numbers are not available, this


PAGE 10


                  Closing Statement will be based upon mutually agreeable estimates from the previous year's tax
                  renditions and payments and from the prior month's Splitter Assets-related financial statements.

         3.03     Allocation.

         (a)      La Porte LP, La Porte GP, Bay Area Pipeline, and OTC.  Buyer and Sellers agree that the
                  valuations and allocations established in Exhibit 3.03 attached hereto and incorporated herein
                  by this reference reflect the fair market value of the Splitter Assets listed therein at the
                  time of Closing.  The Parties further agree that the Purchase Price for the Splitter Assets
                  listed in Exhibit 3.03 shall be allocated among such Splitter Assets in accordance with Section
                  1060 of the Internal Revenue Code of 1986, as amended.  Sellers and Buyer agree to cooperate in
                  good faith in the allocation of the Purchase Price and the completion and filing of the United
                  States federal income tax Form 8594 in accordance with such price allocation.  The Parties
                  further agree that they will report the tax consequences of the purchase and sale hereunder in
                  a manner consistent with the valuations established in Exhibit 3.03 and that they will not take
                  any positions inconsistent therewith in connection with the filing of any tax return.

         (b)      Remaining Splitter Assets. Sellers and Buyer agree that the Purchase Price (as adjusted pursuant
                  to the terms of this Agreement) will be allocated among the Splitter Assets not listed on
                  Exhibit 3.03 hereto for all purposes (including tax and financial accounting purposes) as
                  jointly agreed between Buyer and Sellers within forty-five (45) days after the Closing Date.
                  Buyer, Sellers and their applicable Affiliates will file all tax returns and forms in a manner
                  consistent with such allocation.  Should, by the end of such 45-day period, the Parties be
                  unable to agree on such allocation as contemplated by this Section 3.03(b), the Parties'
                  disagreement with respect thereto shall be referred to the Accounting Firm which shall resolve
                  such dispute, which resolution shall be final and binding, in the manner provided for in
                  Section 7.01(b) hereof.

                  intends to terminate or alter the provisions thereof by reason of the transaction contemplated
                  by this Agreement or otherwise.  True and correct copies of all Contracts have been delivered
                  or made available to Buyer, which delivery or availability is hereby acknowledged by Buyer.

         (h)      Permits.  Except for permits and licenses within the definition of Real Property Instruments
                  under Section 4.01(i), the Permits (as listed on Schedule 4.01(h)) are all of the permits,
                  licenses, orders, or authorizations issued by a Governmental Body that are presently held by
                  Sellers, by Diamond Shamrock Refining and Marketing Company (as the operator of the P/P
                  Splitter Facility), or by D-K LLC (as operator of the La Porte Pipeline), and to the Knowledge
                  of Sellers required or necessary for the ownership, use, or operation of the Splitter Assets as
                  currently owned, used, and operated by Sellers.  Sellers will transfer or cause the transfer of
                  all Permits listed on Schedule 4.01(h), to the extent that such Permits are transferable,
                  pursuant to the applicable permitting agency required form.   Sellers will cancel or cause the
                  cancellation of all non-transferable Permits effective as of the Effective Time.

         (i)      Real Property Instruments.  Schedule 4.01(i) sets forth a list of all deeds, leases, easements,
                  rights-of-way, real property rights, and licenses (other than the Ground Lease) relating to
                  Sellers' ownership, use, maintenance, and operation of the Splitter Assets and La Porte LP's
                  ownership, use, maintenance, and operation of the La Porte Pipeline ("Real Property
                  Instruments").  Except as provided for in Schedule 4.01(i), Sellers have not received written
                  notice that they are in default under the terms of any Real Property Instrument; to the
                  Knowledge of Sellers, Sellers are not in material default under the terms of any Real Property
                  Instrument; nor has any event occurred which, with the passage of time or giving of notice, or
                  both, would constitute such a default.  Except as provided for in Schedule 4.01(i), to the
                  Knowledge of Sellers, no other Person that is a party to any Real Property Instrument is in
                  material default under the terms of any Real Property Instrument; nor has any event occurred
                  which, with the passage of time or giving of notice, or both, would constitute such a default
                  of such a Person.

         (j)      Intellectual Property Interests.  To the Knowledge of Sellers, Schedule 4.01(j)-I sets forth a
                  list of all material trademarks, licensed processes or rights and other intellectual property
                  (collectively, "Intellectual Property Interests") which burden or benefit the operation, use,
                  or maintenance of the Splitter Assets.  Schedule 4.01(j)-II lists the Intellectual Property
                  Interests that will be transferred to Buyer hereunder (the "Transferred Intellectual Property
                  Interests").  Schedule 4.01(j)-II lists certain proprietary Intellectual Property Interests
                  (the "Proprietary Intellectual Property Interests") developed by Sellers or, as specified in
                  Schedule 4.01(j)-II, for which only the data relating thereto will be transferred to Buyer.
                  Schedule 4.01(j)-II further contains restrictions applicable to the transfer of certain of the
                  Transferred Intellectual Property Interests, including the terms of such a transfer.  Except as
                  set forth in Schedule 4.01(j)-II, Sellers are the owners of, or duly licensed to use, each
                  Transferred Intellectual Property Interest, and there are no Orders limiting Sellers' rights to
                  use the Transferred Intellectual Property Interests or determining that Sellers' possession or
                  use thereof infringes upon any Person's rights; nor, to the Knowledge of Sellers, are there any
                  Proceedings in which any Person seeks to limit Sellers' rights with respect to the Transferred
                  Intellectual Property Interests or claims infringement by Sellers as a result of Sellers' use
                  or possession of such Intellectual Property Interests.  Subject to any consent required as
                  referenced in Section 6.07, the consummation of the transactions contemplated by this Agreement
                  will not result in the impairment of the Buyer's right to use any such Transferred Intellectual
                  Property Interests or infringe upon the intellectual property rights of any third Person.
                  Notwithstanding anything to the contrary contained herein, the names "Diamond-Koch," "Koch," or
                  "Diamond" or any variation thereof and any marks or goodwill associated therewith are not
                  "Intellectual Property Interests."

                  (1)      Each of the Sellers (A) have timely filed, or shall cause to be filed, returns

                  with the Splitter Assets or the owners thereof (except OTC), and the information contained in
                  each such return was, or shall be at the time of filing, true, complete, and accurate, and (B)
                  have paid or shall provide for the payment of and pay when due such taxes required to be paid
                  in respect of periods for which such returns were due.

                  (2)      Except as provided for in Schedule 4.01(k), no written notice of any proposed
                  deficiency, claim, assessment, or levy with respect to taxes has been received by Sellers with
                  respect to the Splitter Assets or the owners thereof (except OTC), which has not been paid.

                  (3)      Except as provided for in Schedule 4.01(k), no ruling has been issued to Sellers (or
                  closing agreement or gain recognition agreement to which any such entity is a party or is
                  otherwise bound) concerning taxes from (or with) any Governmental Body which would have
                  continuing effect on the Splitter Assets (except OTC) after the Effective Time.

                  of this Section 4.01(k) are also true and correct as to OTC, it being agreed, however, that
                  Sellers are not the operator of OTC and do not handle tax matters for OTC.

                  (6)      Except for sales and use or similar taxes which result from the consummation of the
                  transactions contemplated by this Agreement, to the Knowledge of Sellers, Sellers have
                  collected, or will collect, all sales and use or similar taxes required to have been collected
                  prior to the Effective Time, and has remitted, or will remit, to the proper Governmental Body
                  all such taxes required to be remitted prior to the Effective Time.  Sellers have maintained,
                  and to Sellers' Knowledge, La Porte LP and La Porte GP have in their possession all records,
                  supporting documents, and exemption certificates required by applicable sales tax statutes and
                  regulations to be retained in connection with the collection and remittance of sales and use
                  taxes for all periods up to the Effective Time.

                  (7)      Sellers own the Splitter Assets identified in Sections 2.02(a) and 2.02(c) in
                  undivided interests and the relevant Sellers shall make or cause to be made elections under
                  Section 754 of the Internal Revenue Code for La Porte GP and La Porte LP and provide Buyer with
                  statements of such Section 754 elections signed by all of the owners of La Porte GP and La
                  Porte LP.

                  (8)      None of the Sellers are a "foreign person," within the meaning of Section 1445(f)(3)
                  of the Code.

                  (9)      Neither La Porte LP nor La Porte GP is a party to, is bound by or has any obligation
                  under any tax sharing, tax indemnity or tax allocation agreement or similar tax agreement or
                  arrangement.

                  (10)     La Porte GP and La Porte LP are, and at all times through the Closing Date will be,
                  classified as "partnerships" for federal income tax purposes.  No election under Treas. Reg.
                  301.7701-3 shall be made by or with respect to La Porte GP or La Porte LP to alter such
                  classification.

         (l)      Compliance.  Except as set forth on Schedule 4.01(l):

                  (1)      Sellers have granted no options or rights to purchase, sublease, or otherwise acquire
                  any interest in the Splitter Assets and Sellers have the right of possession of the Splitter
                  Assets.

                  (2)      To the Knowledge of Sellers, the present use of the Splitter Assets is in substantial
                  conformity with all applicable existing Orders, Permits and Legal Requirements and with all
                  deed restrictions of record and Sellers have not received written notice of any violation or

PAGE 15


         5.01     Buyer. Buyer represents and warrants to Sellers that the matters set forth below in this
Section 5.01 are as of the date hereof, and further warrants that such representations and warranties shall be as
of Closing, true and accurate in all material respects in accordance with their terms:

         (a)      Organization and Standing.  Buyer is a limited partnership duly organized, validly
                  existing, and in good standing under the laws of the State of Delaware.

         (b)      Authorization.  Being approved by the general partner of Buyer, Buyer has the power and
                  authority to enter into and perform this Agreement and the other documents to be executed by

                  transactions contemplated hereby.

         (c)      Enforceability.  This Agreement has been, and at the Closing the other documents to be
                  executed by Buyer will have been, duly executed and delivered by Buyer and constitute or will
                  constitute the legal, valid and binding obligations of Buyer, enforceable in accordance with
                  its terms, except as that enforceability may be (1) limited by an applicable bankruptcy,
                  insolvency, reorganization, moratorium, or similar laws affecting the enforcement of creditors'
                  rights generally, and (2) subject to general principles of equity (regardless of whether such
                  enforceability is considered in a Proceeding in equity or at law).

         (d)      Legal Proceedings.  Except as set forth on Schedule 5.01(d), there are no outstanding
                  Orders of any Governmental Body or, to the knowledge of Buyer, any Proceedings which would
                  prevent it from consummating the transactions contemplated by this Agreement and, to the
                  knowledge of Buyer, there are no Proceedings threatened in writing or pending against,
                  involving, or which might affect or impair the Splitter Assets.

         (e)      No Violations.  This transaction will not (i) violate or conflict with any provision of

                  Act; or (B) approvals from those Governmental Bodies (other than pursuant to the HSR Act) or
                  other Persons listed in Schedule 5.01(e).

         (f)      Securities Representation.  Buyer is acquiring the Splitter Assets for Buyer's own
                  account and not with a view to, or for offer of resale in connection with, a distribution

                                                    ARTICLE VI
                                                 COVENANTS

         6.01     Casualty Loss/Condemnation.

         (a)      Casualty Loss.  Prior to the Effective Time, if all or any portion of the Splitter
                  Assets have been or are destroyed by fire, flood, storm, or other casualty of a similar nature
                  (all of which are herein called a "Casualty Loss") and if such Casualty Loss is reasonably
                  determined to require repairs that will cost in excess of fifty percent (50%) of the Purchase
                  Price, then either Party shall have the right and option to declare this Agreement to be
                  terminated by written notice given to the other Party within thirty (30) days after the
                  occurrence of the Casualty Loss.  Should such damage not be to such extent or should it be to
                  such extent but neither Party elects to so terminate this Agreement, then Sellers shall proceed
                  to repair any such damage or destruction as soon as is reasonably practicable following the


PAGE 16


                  expiration of said thirty (30) day period to the condition and operating levels and
                  efficiencies as existed immediately prior to such Casualty Loss, and upon completion of such
                  repair and all necessary testing and start-up, the transaction contemplated hereby will close,
                  subject to the other terms of this Agreement. Any insurance proceeds relating to a Casualty
                  Loss occurring while Sellers have the risk of loss shall be the sole property of Sellers.  The
                  risk of Casualty Loss occurring after the Effective Time with respect to the Splitter Assets
                  shall pass to Buyer at Closing.

         (b)      Condemnation.  If, prior to the Effective Time, all or a portion of the Splitter Assets
                  are taken by condemnation or are subject to being taken by a written threat of condemnation,
                  and if such taking or threat of a taking does, or would, materially limit Buyer's use of the
                  Splitter Assets or its ability to benefit from the full value to be paid for the Splitter
                  Assets, then Sellers shall promptly give written notice of such condemnation or condemnation
                  proceedings to Buyer and Buyer may terminate this Agreement upon prior written notice to
                  Sellers of at least fourteen (14) days or the number of days left until Closing, whichever is
                  fewer.  If Buyer terminates this Agreement under this Section 6.01(b), any payments made under
                  threat of condemnation or condemnation awards shall be the sole property of Sellers.  If Buyer
                  does not elect to terminate this Agreement, or cannot terminate this Agreement because the
                  taking or threatened taking did not or would not materially limit Buyer's use of the Splitter
                  Assets or its ability to benefit from the full value to be paid for the Splitter Assets, such
                  payments or awards shall be the sole property of Buyer.

         6.02     Conduct of Business Between Signing of this Agreement and Effective Time.

         (a)      Between signing of this Agreement and the Effective Time, Sellers shall preserve and maintain
                  the Splitter Assets in the ordinary course of business consistent with past practice.

         (b)      Without the consent of Buyer (which consent will not be unreasonably withheld or delayed), and
                  prior to the Closing, Sellers shall not and shall not commit or agree to do, any of the
                  following:

                  (1)      waive, compromise, or settle any right or Proceeding involving or relating to the
                  Splitter Assets or any Liabilities/Claims in respect thereof which singularly or in the
                  aggregate exceed Fifty Thousand Dollars ($50,000.00);

                  (2)      create, incur, or assume any Lien on or with respect to any Splitter Assets or any
                  income or profits therefrom;

                  (3)      enter into or agree to any agreement or arrangement granting any rights to purchase
                  any of the Splitter Assets or the assets of La Porte Pipeline, except for agreements relating
                  to sales of inventory in the ordinary course of business consistent with past practices;

                  (4)      enter into, renew, extend, amend, or terminate any Contract or renew, amend, or
                  terminate any Real Property Instrument; and any other contracts relating to the operation, use,
                  or conduct of the business of the Splitter Assets may be entered into by Sellers only in the
                  ordinary course of business consistent with their past practice; provided that the aggregate
                  amount of obligations of all such other contracts shall not exceed Five Hundred Thousand
                  Dollars ($500,000.00);

                  (5)      except as specifically provided for herein, transfer or sell, or agree to transfer or
                  sell, any part of the Splitter Assets; or

                  (6)      except as otherwise provided for herein, terminate any Real Property Instrument or
                  Permit.

         6.03     Compliance with Conditions Precedent.  Each Party shall use its commercially reasonable
efforts to cause the conditions precedent to Closing set forth in Sections 8.02 and 8.03, applicable to such
Party, to be fulfilled and satisfied as soon as practicable but in any event prior to Closing.


PAGE 17


         6.04     Press Release.  Buyer expects to issue a press release upon the execution of this
Agreement.  Buyer and Sellers shall consult with each other in a good faith effort to agree upon the
mutually-acceptable substance of such a press release and with regard to all publicity and other releases issued
at or prior to Closing concerning this Agreement and the transactions contemplated hereby, and except as required
by Legal Requirements, neither Party shall issue any publicity or other release without the prior written consent
of the other Party (which such consent may not be unreasonably withheld or delayed).

         6.05     Insurance.   Sellers shall keep, or cause to be kept, all existing insurance policies on
the Splitter Assets in full force and effect through the close of business on the Closing Date.

         6.06     Consents to Assignment - Formation of Diamond-Koch.  Schedule 6.06 lists the Contracts
and Real Property Instruments for which consent to assignment (including waivers of rights of first refusal or
preferential purchase rights) is required, that were to be assigned to D-K I or D-K III in connection with the
formation of the Diamond-Koch venture of which D-K I and D-K III are a part, and with respect to which such
consent has not yet been obtained.  Sellers shall, at Sellers' sole cost and expense, use reasonable commercial
efforts and diligence to obtain all such required consents, approvals, and waivers and deliver evidence of same
reasonably satisfactory to Buyer as soon as reasonably practicable and whether before or after the Closing Date.
Any and all cost and expense relating to such consents, approvals, and waivers obtained pursuant to this Section
6.06 shall be Sellers' sole obligation.

         6.07     Consents to Assignment to Buyer.

         (a)      Buyer's Obligations.  If the assignment or transfer of Contracts, Real Property
                  Instruments or Permits hereunder requires the consent of a third Person, except to the extent
                  of Sellers' undertakings pursuant to Sections 6.06, 6.07(b) and 6.07(d), Buyer, at its sole
                  cost and expense, hereby assumes all obligations and responsibilities of obtaining such
                  consents.

         (b)      Sellers' Pre-Closing Obligations.  With respect to the required consents referenced in
                  Section 6.07(a), upon the execution of this Agreement, Sellers will use commercially reasonable
                  diligence to obtain such consents from the Persons from whom consent is required.  To the
                  extent commercially reasonable, Sellers shall obtain such consents prior to Closing and shall
                  provide documentation of such consents to Buyer at Closing. Notwithstanding anything to the
                  contrary provided for in this Section 6.07(b) above, if the Closing occurs within five (5)
                  Business Days after the date of this Agreement, Sellers need not perform the covenants provided
                  for in this Section 6.07(b), and Buyer shall be responsible for initiating and completing the
                  consent requests described herein.

         (c)      Consents Not Obtained by Closing.  Except as provided in Section 7.04, at Closing,
                  Sellers shall provide their files to Buyer relating to their efforts to obtain the consents not
                  obtained by Closing if required pursuant to Section 6.07(b).  Buyer shall thereafter exercise
                  reasonable diligence to obtain such consents.   The Parties shall assist each other with
                  respect to obtaining such consents until Sellers' obligations expire as provided for in the
                  last sentence of this Section 6.07(c) or until such other time as mutually agreed. With respect
                  to Contracts and Real Property Instruments for which consents are not obtained by Closing
                  including the consents referred to in Section 6.06 (or, despite Buyer's efforts after Closing,
                  are not later obtained) (respectively the "Non-Conveyed Contracts" and "Non-Conveyed Real
                  Property Instruments"), Sellers shall, upon Buyer's written request, take commercially
                  reasonable steps and actions to provide Buyer with the benefit of such Non-Conveyed Contracts
                  and Non-Conveyed Real Property Instruments.  Buyer shall enter into subcontracting or other
                  beneficial arrangements with Sellers or an Affiliate thereof pursuant to which Buyer shall
                  fulfill such obligations or liabilities at no additional expense to Sellers except Sellers' own
                  costs in entering into, administering, and managing such arrangements.  Sellers' obligation to
                  provide such benefit with respect to a particular Non-Conveyed Contract shall expire
                  concurrently with the earlier of (a) the expiration of that Non-Conveyed Contract according to
                  its terms or (b) the earliest time that such Non-Conveyed Contract may be terminated by Buyer


PAGE 18


                  (as Sellers' assignee) without breach thereof.   Sellers' obligation to provide such benefit
                  with respect to all Non-Conveyed Real Property Instruments shall expire concurrently with the
                  expiration of that Non-Conveyed Real Property Instrument according to its terms.

         (d)      Certain Real Property Instruments.  Notwithstanding anything to the contrary contained in
                  Sections 6.07(a), (b) or (c), the provisions of this Section 6.07(d) govern consents to
                  assignment of Non-Conveyed Real Property Instruments pertaining to the following pipelines:
                  Amoco Lateral, Solvay Lateral, MCO Lateral, MCO to Texas City Pipeline, Amoco (Texas City)
                  Lateral, and ARCO Lateral.  If, by Closing, any required consents for such Non-Conveyed Real
                  Property Instruments have not yet been obtained, Sellers will continue to pursue such consents,
                  with Buyer's assistance, until Sellers' obligations expire as provided for in the last sentence
                  of Section 6.07(c) or until such other mutually agreed time.  If, as a condition to granting
                  such consent, the landowner/grantor requires a one-time payment, and if Sellers, without making
                  such payment, are unable to provide Buyer with the benefit of that Non-Conveyed Real Property
                  Instrument, Sellers shall make the one-time payment and secure the required consent unless the
                  landowner/grantor specifically states or indicates that payment is being required because of
                  the identity of Buyer. Sellers covenant and agree that they will not suggest, imply, or in any
                  manner or fashion influence the landowner/grantor to make such a statement or indication.  If,
                  however, as a condition of granting consent, the landowner/grantor requires some other
                  modification to the terms and conditions of the Non-Conveyed Real Property Instrument
                  (including an increase in periodic fees due thereunder), and if without agreement to such
                  modification Sellers are unable to provide Buyer with the benefit of that Non-Conveyed Real
                  Property Instrument, then, Buyer shall either agree to such modifications (or negotiate a
                  mutually agreed upon modification with the landowner/grantor) and obtain such consent, or
                  failing such, Sellers shall be relieved of all obligations to secure such consent for that
                  Non-Conveyed Real Property Instrument and Sellers shall have no further obligation or liability
                  with respect thereto except as set forth below with respect to annual increases in periodic
                  fees.  Sellers covenant and agree that if a landowner/grantor advises Sellers that a one-time
                  payment of a Non-Conveyed Real Property Instrument will be required in order to secure consent,
                  Sellers shall not, without first consulting Buyer, suggest to the landowner/grantor other means
                  of securing the consent (such as modifications of the applicable Non-Conveyed Real Property
                  Instrument) without first requesting Buyer's approval of such other means, which approval shall
                  not be unreasonably withheld, delayed, or conditioned.  Sellers further covenant and agree that
                  if a landowner/grantor advises Sellers that modifications are required to secure the consent,
                  Sellers will promptly notify Buyer of the requested modifications without negotiation with the
                  landowner/grantor.

                  With respect to increases in periodic fees required by landowners/grantors to secure consent,
                  if the sum of all increases in such periodic fees with respect to the Non-Conveyed Real
                  Property Instrument, on an annual basis, exceeds Seventy-Five Thousand Dollars ($75,000.00)
                  annually, Sellers shall be obligated to pay Buyer an amount equal to the net present value of
                  the difference between (i) the sum of all periodic fee increases and (ii) $75,000.00, over a
                  five year period, using a discount rate of Eight Percent (8%).  For example, if the sum of all
                  periodic fee increases total $100,000, Sellers will owe Buyer the net present value of a
                  $25,000.00 payment stream over a five year period using the 8% discount rate, or $99,817.00.

                  Nothing in this Section 6.07(d) modifies the terms of the last sentence of Section 6.07(c).

         (e)      Consents - Permits.  Sellers shall have no obligations or liabilities with respect to
                  any non-assignable or non-transferable Permits. Buyer assumes all responsibility and
                  obligations for replacing or transferring all Permits and obtaining any permits it may require
                  to own or operate the Splitter Assets.

         6.08     Assumed Contracts/Instruments.  Buyer agrees to assume all rights and obligations of
Sellers arising under the Contracts, Real Property Instruments, Transferred Intellectual Property Interests,
Permits, and any contractual commitments made in accordance with Section 6.02 (to the extent transferable) on and


PAGE 19


after the Effective Time to the extent such rights and obligations accrue after the Effective Time and are
incurred in accordance with Section 6.02.

         6.09     Inspection.        Prior to Closing, at any reasonable time and from time to time upon
reasonable advance notice to Sellers, Sellers shall permit the representatives of Buyer to inspect the Splitter
Assets and observe the operating and maintenance personnel therein employed, and to further observe any and all
activities related to the maintenance, operation, contracting, and administration thereof.  Buyer's
representatives shall be entitled to make copies of any Records.  Notwithstanding the foregoing, Sellers shall
not be required to grant access to or furnish information which Sellers consider, in their sole judgment, to be
confidential to Sellers or to others or which might disclose any techniques or applications which Sellers
consider to be business secrets or proprietary information to Sellers.  All information furnished to Buyer
pursuant to this provision will be deemed to be "Confidential Information" for purposes of that certain
"Confidentiality Agreement" described in Section 12.03 below.  All inspections shall be conducted in compliance
with all of Sellers' applicable safety procedures, rules, and regulations in effect at the Splitter Assets from
time to time, which shall include, without limitation, site safety training and access restriction procedures as
are normally required by Sellers of third party invitees.  No investigation by Buyer will affect any
representation or warranty given by Sellers to Buyer or the remedies available to Buyer hereunder.

                                                    ARTICLE VII
                                          POST-CLOSING AGREEMENTS

         7.01     Final Recapitulation Settlement; Subsequent Audits and Settlements.  With respect to
final recapitulation and audits:

         (a)      Within ninety (90) days after the Closing Date (the "Final Recap Date"), Sellers shall provide
                  to Buyer, for Buyer's review, a proposed final recapitulation settlement in the form of the
                  Preliminary Settlement Statement (the "Final Recap Statement") to account for all actual
                  adjustments to the Purchase Price (and Net Inventory) known as of the Final Recap Date if such
                  actual adjustments differ from those shown on the Closing Statement provided prior to Closing
                  pursuant to Section 3.02 (the "Final Recap").  These adjustments shall be identified to the
                  associated Splitter Asset.  Buyer shall have the right, within one hundred eighty (180) days
                  after the Closing Date, to complete an audit of the Final Recap Statement.  If Buyer disagrees
                  with the Final Recap Statement, Buyer and Sellers shall use their respective commercially
                  reasonable efforts to reach agreement within thirty (30) days following Buyer's completion of
                  its audit of the Final Recap Statement.

         (b)      Should the Parties be unable to resolve any disagreements concerning the Final Recap Statement,
                  such disagreement shall, at the earliest practicable date, be referred, by either or both of
                  the Parties, to a nationally recognized accounting firm mutually acceptable to Buyer and
                  Sellers (the "Accounting Firm"), along with all audit reports, work papers, schedules, and
                  calculations related to the matter in dispute.  Within twenty-five (25) days after such
                  submission, the Accounting Firm shall issue a letter report determining the Final Recap, which
                  shall be final and binding.  Any fees and expenses incurred in resolving disputes shall be
                  borne by the Party incurring such, except for the Accounting Firm, which shall be borne equally
                  by Buyer on the one hand and Sellers on the other hand.

         (c)      Payment of any amounts owed under the Final Recap is due within ten (10) days after the date
                  Sellers and Buyer agree on the Final Recap Statement, or within ten (10) days after the
                  determination of the Final Recap by the Accounting Firm, whichever is later.


PAGE 20


         7.02     Accounts Receivable.         After Closing, Sellers agree to cause to be paid to Buyer
any amounts received by Sellers, including accounts receivables generated by the Splitter Assets after the
Effective Time, to which Buyer is entitled but which is made instead to Sellers for whatever reason.  After
Closing, Buyer agrees to cause to be paid to Sellers any amounts received by Buyer after the Effective Time,
including accounts receivables generated by the Splitter Assets prior to the Effective Time, to which Sellers are
entitled but which are made instead to Buyer for whatever reason.

         7.03     Recording.  Except for the recording of the consents or approvals to the assignments
described in Section 6.06 (for which Sellers shall promptly furnish the recording information to Buyer), Buyer
shall be solely responsible for promptly recording the assignments and any other instruments related to the
conveyance of any of the Splitter Assets, and shall promptly furnish Sellers with the recording information.  All
recording and filing fees for instruments to be recorded by a specified Party shall be paid by that Party.

         7.04     Files and Records. At or prior to the Closing, Sellers shall permit Buyer to take
possession of the original set of all hard copy and electronic Records in Sellers' possession and  located at
Sellers' Mont Belvieu, Texas, or Houston, Texas, offices.  Other Records shall be made available to Buyer within
thirty (30) days after the Closing Date at either Mont Belvieu, Texas, or Houston Texas, as designated by Buyer;
provided, however, that Sellers shall, if reasonably needed by Buyer, make copies of such other Records available
to Buyer upon Buyer's request prior to such time at Sellers' sole expense. With respect to the accounting records
that are not part of the Records, including all records that Buyer may need in order to prepare financial
statements in accordance with generally accepted accounting principles for filing with the Securities and
Exchange Commission, Sellers shall make available to Buyer such records for inspection and copying during normal
business hours.  From time to time as requested by Sellers, Buyer shall make such files, records, and data which
it acquires from Sellers and which are reasonably required by Sellers available to Sellers for inspection and
copying during normal business hours, together with such additional non-privileged, non-protected files, data,
and records of Buyer as relate specifically to the Splitter Assets as may be required by Sellers in order to
pursue any of their claims, obligations, and disputes relating to the Splitter Assets.  If there are records that
relate to the Excluded Assets that also relate to the Splitter Assets, Sellers shall have the right to redact any
information contained therein that relates exclusively to the Excluded Assets.

         7.05     Use of Sellers' Names.  By no later than one hundred and twenty (120) days after
Closing, Buyer shall have covered, removed or caused to have been removed the names and marks of and used by
Sellers and all variations and derivations thereof and logos relating thereto from the Splitter Assets and shall
either remove all pipeline markers that bear Sellers' names or place permanent stickers over Sellers' specific
information (i.e., name and telephone number) on such markers. After expiration of such time period specified
above, Buyer shall not make any use whatsoever of those names, marks, and logos.  If Buyer has not completed such
removal within one hundred and twenty (120) days after Closing, Sellers shall have the right, but not the
obligation, to take such steps as are required to complete such name change and removal or cause such name change
and removal to be completed and Buyer shall reimburse Sellers for any costs or expenses incurred by Sellers in
connection therewith.

         7.06     Further Assurances.  Each Party shall, from time to time at the reasonable request of
the other, and without further consideration, execute and deliver such other instruments of sale, transfer,
conveyance, assignment, clarification, and termination, and take such other action as the Party making the
request may reasonably require to fully effectuate the transactions contemplated hereby, including those required
to sell, transfer, convey, and assign to, and vest in Buyer, and to place Buyer in possession of the Splitter
Assets, or, if necessary, to ensure that Buyer has no interest in any Excluded Asset or Excluded Liability and
that any interest in such an Excluded Asset or Excluded Liability incorrectly conveyed to Buyer is reconveyed to
Sellers. Sellers intend to convey the Splitter Assets at Closing; provided, however, that if it is determined
after Closing that:  (i) any part of the Splitter Assets were not owned by Sellers and that the title to any part
of the Splitter Assets is incorrectly in the name of another entity, or (ii) any Excluded Asset or Excluded
Liability is conveyed to Buyer and that the title to such Excluded Asset is incorrectly in the name of Buyer or
any Excluded Liability is for the account of Buyer, then each Party shall take all such action necessary to
promptly and correctly convey any part of the Splitter Assets to Buyer, or any part of the Excluded Assets or
Excluded Liabilities to Sellers.


PAGE 21


         7.07     Post-Closing Tax Proceedings.  If Buyer or any of its Affiliates receives notice of any
examination, adjustment, or other Proceeding relating to the liability for taxes of or with respect to Sellers
and concerning the Splitter Assets for any period prior to the Effective Time, Buyer shall notify Sellers in
writing within five (5) business days of receiving notice thereof (or such lesser time if such notice given to
Buyer requires action in less than five (5) business days).  As to any such taxes for which Sellers are or may be
liable, Sellers shall, at Sellers' expense, control or settle the contest of such examination, adjustment, or
other Proceeding, and shall defend (upon Buyer's request) and indemnify Buyer against all losses in connection
therewith.  The Parties shall cooperate with each other and with their respective Affiliates in the negotiations
and settlement of any Proceeding described in this Section 7.07.

         7.08     Sales Taxes. The Purchase Price provided for hereunder excludes any sales tax or other
taxes required to be paid in connection with the sale of the Splitter Assets.  Buyer shall be responsible for all
applicable sales and use taxes, gross receipts, conveyance, transfer, and recording fees, motor vehicle transfer
and excise taxes and registration fees, and real estate transfer taxes and documentary stamp taxes, if any, that
may be imposed on any transfer pursuant to this Agreement.  Buyer shall defend (upon Sellers' request),
indemnify, and hold Sellers harmless for any and all sales, use, gross receipts, and similar taxes, penalties,
and interest imposed on Sellers based on the sale of the Splitter Assets.  To the extent the sale of the Splitter
Assets is a sale of tangible personal property, Buyer shall cooperate with Sellers to provide any applicable
exemption certificates or other documentation necessary to obtain available tax exempt status for the sale of the
Splitter Assets.

         7.09     Other Taxes.

         (a)      All taxes (excluding taxes described in Section 7.08) associated with the ownership, operation
                  or use of any of the Splitter Assets and which have accrued prior to the Effective Time have
                  been or will be properly paid or withheld by Sellers, and all statements, returns, and
                  documents pertinent thereto have been or will be properly filed. Sellers shall indemnify,
                  defend, and hold Buyer harmless from and against all such taxes and related liabilities and
                  obligations.

         (b)      Buyer shall defend (upon Sellers' request) and indemnify Sellers for, and shall be responsible
                  for, paying or withholding or causing to be paid or withheld all taxes associated with the
                  ownership, operation, or use of any of the Splitter Assets which have accrued after the
                  Effective Time and for filing all statements, returns, and documents incident thereto.

                                                   ARTICLE VIII
                                                  CLOSING

         9.01     Disclaimer.  Except for, and without limitation of, the express representations,
warranties, covenants, and agreements (including the indemnity agreements and understandings set forth in Article

the matters set forth in this Article IX, the Parties agree as follows:

         (a)      Buyer hereby acknowledges and agrees that Sellers have not made, do not make, and expressly
                  disclaim any other warranties, representations, covenants, or agreements, either express or

PAGE 25


                  habitability, quantity, quality, environmental condition, or physical condition of the Splitter
                  Assets or their suitability or fitness for any particular purpose or use, and that the Splitter
                  Assets, including the state of the title thereto, are sold to Buyer on an "as-is, where is with
                  all faults" basis;

         (b)      Buyer hereby expressly releases Sellers from any and all responsibilities, liabilities,
                  obligations, and claims, known and unknown, whether based upon negligence, strict liability, or
                  otherwise, arising under Environmental Laws or any other Legal Requirement, including, without
                  limitation, any obligations to take the Splitter Assets back or reduce the Purchase Price, or
                  any actions for contribution or indemnity, or to improve, repair, or otherwise modify the
                  physical condition or operation of the Splitter Assets, that Buyer or its successors or assigns
                  may have against Sellers or that may arise in the future, based, in whole or in part, upon the
                  presence of Hazardous Materials or other Environmental Contamination on, around, within, or
                  under the Splitter Assets or arising from the Environmental Condition or physical condition of
                  the Splitter Assets, regardless of how caused or created (by Sellers' negligence, actions,
                  omissions, or fault, pursuant to any statutory scheme of strict liability, or otherwise).
                  Buyer further acknowledges that the provisions of this Section have been fully explained to
                  Buyer and that it fully understands and accepts the same as a condition to proceeding with this
                  transaction.  Buyer acknowledges that none of Sellers' employees, agents, or representatives
                  have made any statements or representations to Buyer, or to its employees, whether employed by
                  Buyer or any Affiliate of Buyer, or to Buyer's agents or representatives, contrary to the
                  provisions of this Section;

         (c)      Buyer acknowledges that Sellers make no warranty or representation, express, implied,
                  statutory, or otherwise as to the accuracy or completeness of any title opinion, data, reports,

                  other materials furnished or made available to Buyer by Sellers or by Sellers' employees,
                  agents, or representatives.  In entering into and performing this Agreement, Buyer has relied,
                  and will rely, solely upon its independent investigation of, and judgment with respect to, the
                  Splitter Assets and their value;

         (d)      Buyer recognizes and expressly acknowledges that the Splitter Assets may contain asbestos
                  coating, insulation or other asbestos-containing materials (collectively, "Asbestos") and that
                  any such Asbestos may be in a friable or nonfriable condition.  Sellers make no representations
                  or warranties regarding the extent or condition of any Asbestos-containing material associated
                  with the Splitter Assets.  Buyer, as owner and/or operator of the Splitter Assets after

                  obligations relating to any such Asbestos, including those arising under environmental and
                  worker health and safety laws.  Buyer hereby certifies to Sellers that Buyer and its employees,
                  contractors, and agents that may come into contact with such Asbestos will comply with all
                  applicable laws and other governmental requirements relating thereto, including requirements
                  relating to the training of workers in the handling of Asbestos;

         (e)      by virtue of the purchase of the Splitter Assets from Sellers, Buyer acknowledges that Sellers
                  hereby expressly exclude, and do not assign, transfer, or convey to Buyer any rights or
                  benefits of or to any insurance policies of Sellers or Sellers' Affiliates which might relate
                  to, cover, or insure Sellers for loss of or liability arising from the use, ownership, or
                  operation of the Splitter Assets, regardless of whether such assignment, right, or benefit
                  arises by statute, agreement, or operation of law, including but not limited to defense and
                  indemnity benefits attributable to or arising from or under such policies; and


PAGE 26


         (f)      the Parties reiterate, covenant and agree for sake of clarity that nothing in Sections 9.01
                  (a), (b), (c), (d) and/or (e) is intended to, or shall, modify, limit, restrict, condition,
                  impair, or otherwise affect the Sellers' express representations, warranties, covenants, and
                  agreements set forth in this Agreement or in any agreements, documents, or other instruments
                  required to be delivered pursuant to this Agreement.

                           or damage occurred after the Effective Time; provided, that the Parties agree that if
                           the injury or damage occurred prior to the Effective Time, Sellers' indemnity
                           obligation under  Section 10.01(b) shall apply; and

this Article X, Sellers shall indemnify, reimburse, defend, and hold harmless Buyer Indemnitees from and against
any and all Liabilities/Claims arising from or relating to any Offsite Disposal that occurred prior to the
Effective Time.

         10.03    Sellers' Indemnity for Taxes.  Subject to the limitations provided for in this
Article X, Sellers shall indemnify, reimburse, defend, and hold harmless Buyer Indemnitees from and against any

and all Liabilities/Claims relating to taxes and tax obligations associated with the ownership or operation of
the Splitter Assets for any period prior to the Effective Time ("Tax Liability").

         10.04    Sellers' Indemnity Regarding Title.  Subject to the limitations provided for in this
Article X, Sellers shall indemnify, reimburse, defend, and hold harmless Buyer Indemnitees from and against any
and all Liabilities/Claims caused by Title Defect relating to the rights-of-way, easements, and permissions
necessary for the ownership, operation, use, maintenance, or repair of the La Porte Pipeline and the Splitter
Distribution Pipelines or involving the Real Property Instruments associated with the La Porte Pipeline and the
Splitter Distribution Pipelines, but only to the extent that such Title Defect is demonstrated to have existed
before the Effective Time.

         10.05    Limitations on Sellers' Indemnity.

         (a)      With respect to Sellers' obligations under Section 10.01(a) (concerning any breach of Sellers'
                  express representations, warranties, covenants, and agreements), Sellers' liability under the
                  Agreement or relating to the transactions contemplated thereby (of any kind, including for
                  indemnity or otherwise) for any Liabilities/Claims which are the subject of such Section shall
                  be limited (except in the case of actual fraud) in accordance with the following:

                  (1)      to any such Liabilities/Claims which are asserted within two (2) years after the
                           Effective Time by a Buyer Indemnitee giving Sellers written notice in accordance with
                           the provisions of Section 10.13; and

                  (2)      Sellers shall have no liability or obligation to indemnify or reimburse Buyer
                           Indemnitee with respect to such Liabilities/Claims until such time as the aggregate of
                           such Liabilities/Claims (for which timely notice was given) exceeds Five Hundred
                           Thousand Dollars ($500,000.00) (the "Deductible"), at which time Sellers shall
                           indemnify, reimburse, defend, and hold harmless Buyer Indemnitees with respect to
                           amounts in excess of the Deductible up to the Ceiling (as defined below); provided,
                           that in no event shall Sellers' liability for the satisfaction of such
                           Liabilities/Claims exceed, in the aggregate, the sum of Seventeen Million U.S. Dollars
                           ($17,000,000.00) (the "Ceiling"), which Ceiling includes Liabilities/Claims under
                           Sections 10.01(a), 10.02, and 10.04;

         (b)      With respect to Sellers' obligations under Section 10.02 (concerning Sellers' Offsite Disposal
                  indemnity), Sellers' liability under the Agreement, or relating to the transactions
                  contemplated thereby (of any kind, including for indemnity or otherwise) for any
                  Liabilities/Claims which are the subject of such Section shall be limited (except in the case
                  of actual fraud) in accordance with the following:

                  (1)      to any such Liabilities/Claims which are asserted within four (4) years after the
                           Effective Time by a Buyer Indemnitee giving Sellers written notice in accordance with
                           the provisions of Section 10.13; and

                  (2)      Sellers shall have liability only until the aggregate of such Liabilities/Claims (for
                           which timely notice was given) reaches Five Million Dollars ($5,000,000.00) and has
                           been satisfied, whereupon Sellers' liability with respect to such Liabilities/Claims
                           will cease.   The $5,000,000.00 aggregate liability of Sellers under this Subsection
                           shall be counted toward the Ceiling set forth in Section 10.05(a)(2).

         (c)      With respect to Sellers' obligations under Section 10.04 (concerning Sellers' indemnity
                  regarding Title), Sellers' liability under the Agreement or relating to the transactions
                  contemplated thereby (of any kind, including for indemnity or otherwise) for any
                  Liabilities/Claims which are the subject of such Section shall be limited (except in the case
                  of actual fraud) in accordance with the following:


PAGE 28


                  (1)      to any such Liabilities/Claims asserted within one (1) year after the Effective Time
                           by a Buyer Indemnitee giving Sellers written notice in accordance with the provisions
                           of Section 10.13;  and

                  (2)      Sellers shall have no liability or obligation to indemnify or reimburse Buyer
                           Indemnitee with respect to such Liabilities/Claims until such time as the aggregate of
                           such Liabilities/Claims exceeds Five Hundred Thousand Dollars ($500,000.00) (the
                           "Title Deductible"), at which time Sellers shall indemnify, reimburse, defend and hold
                           harmless Buyer Indemnitee with respect to amounts in excess of the Title Deductible;
                           provided, that all liability incurred by Sellers in satisfying such Liabilities/Claims
                           under Section 10.04 shall be counted toward the Ceiling in Section 10.05(a)(2).

         (d)      With respect to Sellers' obligations under Section 10.01(b) (concerning Sellers' indemnity
                  relating to the ownership or operation of the Splitter Assets prior to the Effective Time)
                  Sellers' liability under the Agreement, or relating to the transactions contemplated thereby
                  (of any kind, including for indemnity or otherwise) for any Liabilities/Claims which are the
                  subject of such Section shall be limited (except in the case of actual fraud) in accordance
                  with the following:

                  (1)      to any such Liabilities/Claims which are asserted within five (5) years after the
                           Effective Time by a Buyer Indemnitee giving Sellers written notice in accordance with
                           the provisions of Section 10.13; and

                  (2)      Sellers shall have liability only until the aggregate of such  Liabilities/Claims (for
                           which timely notice was given) reaches Thirty-two Million Five Hundred Thousand
                           Dollars ($32,500,000.00) and has been satisfied, whereupon Sellers' liability with
                           respect to such Liabilities/Claims will cease.   The Ceiling amount of Seventeen
                           Million Dollars ($17,000,000.00) set forth in Section 10.05(a) shall be counted toward
                           the Thirty-two Million Five Hundred Thousand Dollars ($32,500,000.00) aggregate
                           liability of Sellers under this Subsection.

         10.06    Expenditures.  It is the intent of the Parties that any costs, expenses (including
reasonable attorneys' and consultants' fees), or other monetary payments or expenditures (including monies paid
via judgment or settlement) incurred or paid by Sellers or by the Seller Guarantors in satisfying Sellers'
indemnity obligations to Buyer in accordance with the provisions of this Article X, and including defense costs
in defending a Buyer Indemnitee (but excluding Sellers' Defense Costs, as hereinafter defined) shall be
"Expenditures" as that term is used herein.  The Expenditures and Sellers' Defense Costs relating to the aggregate
liability of Sellers and Seller Guarantors under this Article X shall be included toward Sellers' Maximum
Liability (as defined in Section 10.08), and the Expenditures relating to Sellers' or Seller Guarantors'
satisfaction of their indemnity obligations under Sections 10.01(a), 10.02, and 10.04 shall be included toward
the Ceiling (as defined in Section 10.05(a)(2)) and (to the extent that such Expenditures specifically relate to
satisfaction by Sellers or Seller Guarantors of the Offsite Disposal indemnity provided for in Section 10.02)
toward the limit provided for in Section 10.05(b)(2) (dealing with Offsite Disposal, to the extent such
Expenditures specifically relate to Sellers' or Seller Guarantors' satisfaction of their Offsite Disposal
indemnity obligations).

         10.07    Buyer's Indemnity.

         (a)      Except as specifically provided for in Sections 10.01 through 10.06, commencing at the
                  Effective Time, Buyer shall indemnify, reimburse, defend, and hold harmless Sellers, their
                  parent companies, Affiliates, and subsidiaries and their respective partners, members,
                  Affiliates, directors, shareholders, officers, employees, agents, attorneys, representatives,
                  contractors, and subcontractors (collectively, "Sellers Indemnitees") from and against: (1) all


PAGE 29


                  Liabilities/Claims, whether or not caused in whole or in part by the strict liability, fault,
                  or negligence of Sellers, Buyer Indemnitees or any other Person (whether sole, joint,
                  concurrent, or comparative with any strict liability, fault, or negligence of Buyer or any
                  other person) arising from or relating to (A) the ownership or operation of the Splitter Assets
                  by any Person arising after the Effective Time; (B) the condition of the Splitter Assets,
                  whether attributable to periods of time before or after the Effective Time;  or (C) all
                  Environmental Liabilities/Claims (other than those covered by Sections 10.01(a) or 10.02),
                  whether attributable to periods of time before or after the Effective Time; and  (2) all
                  Liabilities/Claims arising from or related to any breach of Buyer's express representations,
                  warranties, covenants and agreements contained herein.

         (b)      Commencing at the earlier of (1) the time when Sellers and Sellers Guarantors, in the
                  aggregate, have incurred or paid Liabilities/Claims totaling the sum of Five Million Dollars
                  ($5,000,000.00) for Offsite Disposal  pursuant to Section 10.02 and the other applicable
                  provisions of this Article X, or (2) the expiration of the period of four (4) years after the
                  Effective Time (whether or not Sellers and Sellers Guarantors have paid or incurred all or any
                  part of the $5,000,000.00 amount), Buyer shall indemnify, defend, and hold harmless Sellers
                  Indemnitees from and against any Liabilities/Claims arising from or relating to Offsite
                  Disposal, whether attributable to periods of time before or after the Effective Time, and
                  whether or not Sellers, but for this Section 10.07(b), would be legally liable to the claimant
                  or to a Buyer Indemnitee or otherwise for such Liabilities/Claims.

         (c)      Commencing at the earlier of (1) the time when Sellers and Sellers Guarantors, in the
                  aggregate, have incurred or paid, after the Effective Time, Sellers' Maximum Liability arising
                  from or related to the Splitter Assets, or (2) the expiration of the period of five (5) years
                  after the Effective Time for any Liabilities/Claims for which notice is given to Sellers after
                  such five (5) year period expires (whether or not Sellers and Sellers Guarantors have paid or
                  incurred Sellers' Maximum Liability), Buyer shall indemnify, defend, and hold harmless Sellers
                  Indemnitees from and against any Liabilities/Claims of any kind or nature (except for a Tax
                  Liability) arising out of or related to the Splitter Assets, whether attributable to periods of
                  time before or after the Effective Time, and whether or not Sellers, but for this Section
                  10.07(c), would be legally liable to the claimant or to a Buyer Indemnitee or otherwise for
                  such a Liability/Claim or a part thereof.

         10.08    Sellers' Maximum Liability.  As reflected above, it is the intent of the Parties
that Sellers have contractual indemnity obligations only under Sections 10.01 through 10.04 (subject to the
limits provided for in this Article X), and that Buyer have contractual indemnity obligations only under Section
10.07 (subject to the limits provided for in this Article X). In no event shall the sum of Sellers' and Sellers
Guarantors' payments for Expenditures, Liabilities/Claims, and Sellers and Sellers Guarantor's costs in defending
themselves ("Sellers' Defense Costs"), including amounts applied toward the Ceiling in Section 10.05(a), exceed
Thirty-two Million Five Hundred Thousand Dollars ($32,500,000.00) ("Sellers' Maximum Liability"), exclusive of
and without limitation of Sellers' obligations under Sections 10.01(c) and 10.03 of this Article X and under
Sections 6.07(b) and 6.07(d) of the Agreement.

         10.09    Sole and Exclusive Remedy.  Other than claims for actual fraud, the right of each
Party to seek indemnification (subject to the limitations provided for in this Article X) from the other Party
pursuant to this Article X shall be the sole and exclusive remedy of each Party against the other under the
Agreement, and subject to the foregoing, it is expressly understood and agreed that, except by virtue of the
indemnification provisions set forth herein, none of the Parties are entitled to any non-contractual indemnity,
contribution, adjustment, reduction, set-off, damages, injunctions, specific performance, or the like in
connection with the transaction contemplated hereby.

         10.10    Limitation.  Notwithstanding anything to the contrary contained in the Agreement,
neither Party:


PAGE 30


         (a)      shall be liable to the other Party for any damages related to or arising in connection with the
                  Agreement or the transactions contemplated hereby other than actual or compensatory damages; it
                  being agreed that no Party shall be liable to the other for indirect, incidental,
                  consequential, exemplary, or punitive damages hereunder, including any lost earnings or
                  profits, losses due to business interruption or diminution in value of the business except to
                  the extent arising from third Persons; or

         (b)      shall be entitled to recover more than once for any one Liability/Claim for which full
                  indemnification is provided hereunder, such as in the case of Liabilities/Claims flowing from
                  the breach of more than one representation, warranty, covenant, or agreement hereunder.

         10.11     [INTENTIONALLY LEFT BLANK]

         10.12    Survival.  Except as set forth below in this Section 10.12, all obligations under the
Agreement, including the indemnification obligations hereunder, shall survive the Effective Time; provided that
the representations and warranties of Sellers and Buyer contained in Sections 4.01(a), (b), (c) and (d) and
5.01(a), (b), (c), (e), (f) and (g) of the Agreement shall survive the Effective Time indefinitely, but subject
to the applicable statute of limitations, and all other representations and warranties of Sellers and Buyer in
the Agreement shall survive the Effective Time for two (2) years; provided that any acknowledgments, waivers, or
representations given in the Agreement may be asserted as a defense by any Party hereunder at any time in
connection with defending a claim or claims asserted by the other Party hereto, or its successors or assigns,
with regard to any of the transactions contemplated by the Agreement; and provided further that Buyer's indemnity
obligations hereunder shall survive the Effective Time indefinitely notwithstanding any otherwise applicable
statute of limitation.

         10.13    Indemnification Procedures.

         (a)      If a Party to be indemnified under the Agreement (an "Indemnitee") learns of facts that the
                  Party believes would entitle that Party to indemnification from the other Party (an
                  "Indemnitor") (including, in the case of Buyer, that would apply toward the Deductible or the
                  Ceiling applicable to Sellers' indemnity obligation hereunder or to the Title Deductible), the
                  Party who has the right of indemnification based upon such facts shall, within sixty (60) days
                  after the month in which that Party learns of such facts, provide written notice to the other
                  Party containing reasonable details and any supporting documentation then known to the
                  notifying Party of the facts upon which the indemnity claim is based.  Supplemental written
                  notices of additional material facts with respect to matters previously noticed will be given
                  promptly by the Party to be indemnified to the other.  Failure to comply with the proper notice
                  provisions of this Section 10.13 shall result in a waiver of the right of a Party to seek
                  indemnification or other relief from the other Party or from the Buyer Guarantor or Sellers
                  Guarantors, as applicable.

         (b)      The Indemnitor shall have the right, at its option and at its own expense, to be represented by
                  counsel of its choice and to participate in the defense, negotiation, and/or settlement of any
                  Liability/Claim for which it is obligated hereunder which results from a Person not affiliated
                  with the Indemnitor ("Third Person Liability/Claim").  If Indemnitor chooses to acknowledge its
                  obligation to indemnify the Indemnitee for such Third Person Liability/Claim, Indemnitor may
                  assume the defense thereof with Indemnitor-selected counsel to which Indemnitee has not
                  reasonably objected.  Should the Indemnitor so elect to assume the defense of a Third Person
                  Liability/Claim, the Indemnitor shall not be liable to the Indemnitee for legal expenses
                  subsequently incurred by the Indemnitee in connection with the defense thereof.  If the
                  Indemnitor assumes such defense, the Indemnitee shall have the right to participate in the
                  defense thereof and to employ counsel (not reasonably objected to by the Indemnitor), at its
                  own expense, separate from the counsel employed by the Indemnitor, it being understood that the
                  Indemnitor shall control such assumed defense.  The Indemnitor shall be liable for the


PAGE 31


                  reasonable fees and expenses of counsel employed by the Indemnitee for any period during which
                  the Indemnitor has failed to assume the defense thereof (other than during the period prior to
                  the time the Indemnitee shall have given notice of the Third Person Liability/Claim as provided
                  above).

         (c)      If the Indemnitor so elects to assume the defense of any Third Person Liability/Claim, the
                  Indemnitee shall cooperate with the Indemnitor in the defense or prosecution thereof.  Such
                  cooperation shall include the retention and (upon the Indemnitor's request) the provision to
                  the Indemnitor of records and information, which are relevant to such Third Person
                  Liability/Claim, and making employees available on a mutually convenient basis to provide
                  additional information and explanation of any material provided hereunder. Whether or not the
                  Indemnitor shall have assumed the defense of a Third Person Liability/Claim, the Indemnitee
                  shall not admit any liability with respect to, or settle, compromise or discharge, such Third
                  Person Liability/Claim without the Indemnitor's prior written consent (which consent shall not
                  be unreasonably withheld). If the Indemnitor shall have assumed the defense of a Third Person
                  Liability/Claim, the Indemnitee shall agree to any settlement, compromise or discharge of a
                  Third Person Liability/Claim which the Indemnitor may recommend and which by its terms
                  obligates the Indemnitor to pay the full amount of the liability in connection with such Third
                  Person Liability/Claim, which releases the Indemnitee completely in connection with such Third
                  Person Liability/Claim and which would not otherwise adversely affect the Indemnitee.

         (d)      Notwithstanding the foregoing, the Indemnitor shall not be entitled to assume the defense of
                  any Third Person Liability/Claim (and shall be liable for the reasonable fees and expenses of
                  counsel incurred by the Indemnitee in defending such Third Person Liability/Claim) if the Third
                  Person Liability/Claim seeks an order, injunction, or other equitable relief or relief for
                  other than money damages against the Indemnitee which the Indemnitee reasonably determines,
                  after conferring with its outside counsel, cannot be separated from any related claim for money
                  damages.  If such equitable relief or other relief portion of the Third Person Liability/Claim
                  can be so separated from that for money damages, the Indemnitor shall be entitled to assume the
                  defense of the portion relating to money damages. The indemnification required by the foregoing
                  sections shall be made by periodic payments of the amount thereof during the course of the
                  investigation, remediation, or defense, as and when bills are received or loss, liability,
                  claim, damage or expense is incurred.

                                                    ARTICLE XI
                                              EMPLOYEE MATTERS

         11.01    Employees

(a)      Buyer may interview and offer employment to any or all of the individuals listed on Schedule 11.01 (the
         "Employees"), which offers of employment shall be effective as of the Effective Time. Buyer shall provide
         to Sellers a list of all of those Employees it wishes to interview or to make offers of employment
         without interviews and shall coordinate interviews with a Sellers-designated representative.  Sellers
         shall (i) cooperate with Buyer in its attempts to hire such Employees who may be offered employment by
         Buyer, (ii) permit Buyer to review the personnel records and such other information concerning such
         Employees as Buyer may reasonably request, subject to obtaining any legally required written permission
         of any affected Employee and subject to any restrictions imposed by applicable law, and (iii) not
         directly or indirectly discourage any Employee from accepting an offer of employment from Buyer.   Buyer
         shall provide to Sellers a list of those Employees it intends to make offers of employment, which list
         shall include the offered salary and location of employment.  Sellers shall, and shall cause their
         owners and their Affiliates to, continue to employ all Employees through the Effective Time, except for
         any Employee who (i) is terminated with the prior written consent of Buyer or (ii) voluntarily resigns.
         Buyer shall also provide to Sellers a list of those Employees who have previously accepted Buyer's
         employment offer on or before seven (7) days prior to the Closing Date. Those Employees accepting


PAGE 32


         employment with Buyer effective as of the Effective Date are herein referred to as the "Hired
         Employees."  Buyer agrees that it will treat the Hired Employees on substantially the same basis as other
         similarly situated employees of Buyer.  Sellers shall not, and shall cause their owners and their
         respective Affiliates to not, solicit the services of any Hired Employee during the one-year period
         following the Closing Date.

(b)      Buyer will be responsible for any severance pay and severance benefits to the extent required under
         federal, state, or local law, or notices required under such laws, with respect to terminations by Buyer
         of Hired Employees occurring after the Effective Time.  Buyer shall defend, indemnify, and hold Sellers
         and their Affiliates harmless from any Liabilities/Claims by any Hired Employee for their wages,
         salaries, bonuses, severance pay, and severance benefits provided under federal, state, or local law,
         notices required under such laws, and compensation or benefits of any kind which have been earned under
         Buyer's employee benefit plans as a result of and related to any of the Hired Employees' employment by
         Buyer after the Effective Time.

(c)      Sellers or their Affiliates shall retain responsibility for payment of the following matters that have
         been earned for the periods prior and up to the Effective Time as a result of the Employees' employment
         with Seller:

         (i)      wages, salaries and bonuses;

         (ii)     severance pay and severance benefits to the extent required under federal, state, or local law,
                  or notices required under such laws, with respect to employees of Sellers who are terminated
                  prior to the Effective Time; and

         (iii)    except as otherwise expressly provided in this Article XI, all liability and obligations under
                  all Employee Benefit Plans, deferred and incentive compensation plans of Sellers or its
                  Affiliates and all employment-based or related claims and matters.

11.02    Employee Benefit Plans.

(a)      As of the Effective Time, Sellers or their Affiliates shall cause the termination of the participation
         of the Hired Employees in all of the savings, Code section 401(k), pension, retirement, medical, dental,
         life insurance, accident and sickness, short-term disability, long-term disability, profit-sharing,
         deferred compensation, stock option, vacation, stock bonus, employee stock ownership, bonus, severance,
         or other similar plans, programs, agreements, and arrangements, including all employee benefit plans as
         defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
         which are maintained by or contributed to by Sellers (the "Plans"), except that the Hired Employees'
         participation in Sellers' or their Affiliates' medical and dental plans shall continue through the last
         day of the month in which the Effective Time occurs.  At the end of the last day of the month prior to
         the month in which the Effective Time occurs, the Hired Employees' participation in Sellers' or their
         Affiliates' medical and dental plans shall terminate. If the "same desk" rule does not apply to the
         Sellers' or their Affiliates' tax qualified savings plan, Sellers shall make distribution to the
         Employees in accordance with the terms of Sellers' or their Affiliates' plan.  Sellers and Buyer shall
         permit direct rollovers to Buyer's plan in cash and participants' loans for electing participants.
         Buyer's tax qualified savings plan permits rollovers of outstanding participants' loans.  If such rule
         applies, the Parties shall cooperate in determining whether a Plan to Plan transfer of assets from
         Sellers' or their Affiliates' tax qualified savings plan to Buyer's tax qualified savings plan can be
         made for the Hired Employees.  If it is determined a transfer of assets can be made, the Parties shall
         promptly arrange a conference call with their respective record keepers of their Plans and direct the
         record keepers to cause a transfer of assets ("TOA"), in a form acceptable to Buyer, and shall establish
         a date for the TOA. The Parties shall urge their respective record keepers to conclude the TOA as
         quickly as possible, but in any event within nine (9) months after the Parties have agreed to the TOA.
         Each Party shall ensure that amendments to its Plan documents necessary to accomplish the TOA are
         submitted to its board of directors prior to the TOA and shall provide the other Party with a copy of
         any such amendment upon adoption.


PAGE 33


(b)      As of the Effective Time, all of the Hired Employees will either be covered or permitted to enroll in
         all of Buyer's Plans in accordance with the terms and conditions of Buyer's plans in effect from time to
         time for its similarly situated employees generally.

(c)      As of the Effective Time, Buyer shall waive or cause the waiver of waiting periods, pre-existing
         condition exclusions, and other limitations on participation otherwise applicable to any Hired Employee
         and qualified dependents (who was covered by an employee group health plan of Sellers or their
         Affiliates and immediately elects to be covered by the group health plan of Buyer) under or with respect
         to all plans maintained by Buyer for such Hired Employees.  Buyer shall recognize or cause to be
         recognized all claims and expenses of Hired Employees during 2002 for purposes of satisfying applicable
         deductible provisions (and any other like adjustments or limitations on coverage) under, and to the
         extent recognized for current employees of Buyer, all applicable group health plans maintained by
         Buyer.  To the extent reasonably required by Buyer, Sellers shall cause Sellers' or their Affiliates'
         plan providers and insurers to provide to Buyer a true and complete listing of all amounts so expended
         (including co-payments and deductibles paid) with respect to each Hired Employee and such other
         information as Buyer may reasonably require in order to properly administer the provisions of this
         Section 11.02(c).

(d)      Without limiting Section 11.01(c)(iii), Sellers shall retain responsibility for all medical, dental,
         life, vision, AD and D, cafeteria, short-term disability, and long-term disability claims by any Hired
         Employee which were incurred on or prior to the Effective Time and for workers' compensation claims
         related to injuries arising from the employment of the Employees for periods prior to the Effective
         Time, in each case to the extent covered by the respective employee benefit plan and/or insurance plan
         or policy of Sellers or their Affiliates, and any claims regarding Sellers' 401(k) Plan which arise out
         of the administration or operation of such Plan prior to the Effective Time.  Sellers will provide
         reasonable assistance, at no cost to Buyer, for the administration or termination of such benefits.

(e)      For purposes of this Section 11.02, a claim for reimbursement under a medical, hospital or dental,
         prescription drug, or similar plan shall be deemed to be incurred on the date that the claim occurs.  A
         claim occurs on the date service is provided and there shall be no continuation of a claim from one day
         to the next.  In the event of a hospitalization commencing on or prior to the last day of the month in
         which the Effective Time occurs, any existing coverage shall cease on the end of the last day of the
         month in which the Effective Time occurs unless the participant elects COBRA continuation coverage.

(f)      To the extent recognized by Sellers, prior employment with Sellers or an Affiliate thereof shall be
         recognized by Buyer for the purpose of determining service awards, vacation eligibility, and for
         eligibility, vesting, and participation under Buyer's employee benefit plans for the Hired Employees but
         not with respect to calculating pension benefit payments; provided, however, that vacation time earned
         and unused while a Hired Employee was employed by Sellers' Affiliate shall be paid by the employing
         Affiliate to the applicable Hired Employees; and provided further, that Buyer shall allow Hired
         Employees to take such accrued and unused vacation on or before the time it would have been required to
         be taken under the Hired Employee's prior employer's policies without pay. Neither the foregoing nor any
         other provision of this Article XI constitutes an assumption of any liability by Buyer with respect to
         any liability or obligation of Sellers, their owners or an Affiliate thereof to or with respect to any
         Hired Employees.  Commencing with the anniversary year of their employment with Buyer, Hired Employees
         will be given vacation recognizing prior years of service with Sellers or their Affiliates on Buyer's
         vacation schedule.

(g)      Nothing in this Article XI should be construed as requiring Buyer to maintain any employee benefit plan
         or prevent Buyer from amending or terminating any employee benefit plan at any time in its sole
         discretion.  Further, nothing herein shall prevent Buyer from terminating any Hired Employee after the
         Effective Time for any reason.

(h)      No provision of this Article XI shall create any third-party beneficiary rights in any Hired Employee
         (or any beneficiary or dependent thereof), including without limitation, any right to continued
         employment with Buyer for any specified period of time after the Effective Time.


PAGE 34


(i)      Sellers and Buyer agree that, with respect to Hired Employees who accept employment with Buyer upon the
         Closing, each will take the position that they respectively meet the definitions of "predecessor" and
         "successor" as defined in Revenue Procedure 96-60 and IRS Regulation Section 31.3121(a)(1)-1(b).  Absent
         a mutual agreement to the contrary, Sellers and Buyer will use the "Standard Procedure" described in
         Section 4 of Revenue Procedure 96-60.  Sellers shall supply to Buyer, with respect to all Hired
         Employees, all cumulative payroll information as of the Effective Time that Buyer shall reasonably
         request in order to comply with IRS Regulation 31.3121(a)(1)-1(b).

                                                    ARTICLE XII
                                          MISCELLANEOUS PROVISIONS

         12.01    Commission.  Each of the Parties hereto represents and warrants that there are no claims
against such Party for brokerage commissions or finders' fees in connection with the transactions contemplated by
this Agreement, and Sellers and Buyer will respectively pay or discharge, and will defend (upon the other's
request) and indemnify the other for brokerage commissions or finders' fees incurred by reason of any action
taken by such indemnifying Party.

         12.02    Assignment.  The terms, provisions, and conditions of this Agreement shall extend to, be
binding upon, and inure to the benefit of the Parties hereto, their respective successors, and assigns.  No Party
will make an assignment of its rights and/or obligations under this Agreement to a Person that is not an
Affiliate of such assigning Party without the prior written consent of the other, which such consent may be
withheld for any reason; provided, that notwithstanding any contrary provision of law, including Texas statutory
law, a merger or consolidation of Sellers or Buyer with or into any other Person (excluding an Affiliate) shall
be an assignment for purposes of this Agreement, and provided further, that the assigning Party, as a condition
to making an assignment to an Affiliate or to obtaining the consent of the other Party to any non-Affiliate
assignment, shall execute and deliver an instrument, in a form reasonably satisfactory to the consenting Party,
by which the assigning party expressly agrees to remain bound by and primarily liable under this Agreement.  Any
assignment or attempted assignment in violation of this Section shall be void.

         12.03    Entire Agreement; Amendments.  This Agreement and the Exhibits and Schedules attached
hereto and incorporated by reference herein contain the entire agreement of the Parties with respect to its
subject matter.  This Agreement supersedes all prior agreements and understandings between the Parties with
respect to its subject matter, except for that certain Confidentiality Agreement dated December 14, 2000, between
the Parties or their Affiliates which shall remain in full force and effect pursuant to its terms with respect to
all information provided by Sellers or any Affiliate of Sellers to Buyer relating to any assets or businesses
other than the Splitter Assets or the assets purchased by Buyer's Affiliate, Enterprise Products Texas Operating
L.P., pursuant to that certain Purchase and Sale Agreement dated January 16, 2002 between Enterprise Products
Texas Operating L.P., as buyer, and D-K I and D-K III, as sellers.   Additionally, Sellers agree to hold in
confidence and not disclose all Splitter Asset-related Confidential Information (as that term is defined in such
Confidentiality Agreement), except and to the extent required to be disclosed by applicable Legal Requirements
(including disclosures necessary or convenient in the winding up of the business related to the Splitter
Assets).  This Agreement may be amended only by a written instrument duly executed by the Parties.  Any condition
to a Party's obligations hereunder may be waived in writing by such Party.  No waiver by any Party of any one or
more defaults by the other in performance of any of the provisions of this Agreement shall operate or be
construed as a waiver of any future default or defaults, whether of a like or different character.

         12.04    Severability.  Each portion of this Agreement is intended to be severable.  If any term
or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not
affect the validity of the remainder of this Agreement.

         12.05    Actions.  Each Party agrees that it shall use its commercially reasonable efforts to take or
cause to be taken all such action as may be necessary for it to consummate the transactions as set forth in this
Agreement and to assure that it will not be under any material corporate, legal, or contractual restriction that
would prohibit or delay the timely consummation of such transactions.

         (a)      This Agreement may be terminated at any time on or prior to the Closing:

                  (1)      by mutual written consent of Sellers and Buyer;

                  (2)      by Sellers on the Closing if the conditions set forth in Section 8.03 have not been
                  satisfied by Buyer or waived by Sellers in writing by the Closing;

                  (3)      by Buyer on the Closing if the conditions set forth in Section 8.02 have not been
                  satisfied by Sellers or waived by Buyer in writing by the Closing;

                  (4)      pursuant to Section 6.01; and

                  (5)      by either Party, if there shall be any final, non-appealable order, writ, injunction
                  or decree of any Governmental Body binding Sellers or Buyer which prohibits or restrains
                  Sellers or Buyer from consummating the transactions contemplated hereby.

         (b)      If the Closing does not occur as a result of either Sellers or Buyer exercising its right to
                  terminate pursuant to this Section 12.06, this Agreement shall be null and void, and no Party
                  shall have any rights or obligations under this Agreement, except that:

                  (1)      All filings, applications and other submissions made to any Governmental Body shall,
                  to the extent practicable, be withdrawn from the Governmental Body to which they were made;

                  (2)      A termination shall not relieve any Party from any liability for breach hereof
                  occurring prior to termination, and the non-breaching Party shall be entitled to any and all
                  relief under applicable law or in equity on account of such breach; and

                  (3)      Buyer's indemnification and related obligations under the Confidentiality Agreement
                  referenced in Section 12.03 shall survive any such termination.

         12.07    Counterparts.  This Agreement may be executed simultaneously in any number of
counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the
same instrument.

         12.08    Governing Law.  This Agreement shall be governed by, enforced in accordance with, and
interpreted under the laws of the State of Texas, without regard to itS conflicts of law principles.

         12.09    Preparation of Agreement/Relationship of Parties.  This Agreement was prepared jointly
by the Parties hereto and not by either to the exclusion of the other.  Neither Party hereto stands in any
fiduciary or confidential relationship to the other Party; nor are the Parties hereto partners, joint venturers,
or otherwise in a relationship imposing any fiduciary duty on one Party to the other Party.  Each Party
acknowledges and agrees that it has a duty to read this Agreement and all Exhibits and Schedules hereto, and all
documents and instruments referred to herein or in such Exhibits and Schedules; that it has in fact read this
Agreement and is fully informed and has full notice and knowledge of its terms, conditions, and effect; that it
has been represented by legal counsel of its choice throughout the negotiations preceding its execution of this
Agreement and has received the advice of such counsel in connection therewith; and that it recognizes that
certain of the terms of this Agreement provide for the assumption by one Party of, and/or release of the other
Party from, certain liabilities that such Party would otherwise be responsible for under law.  Each Party hereby
agrees that it will not contest the validity or enforceability of any provisions of this Agreement on the basis
that the Party had no notice or knowledge thereof or that such provisions are not "conspicuous."

         12.10    Notices and Addresses.  (a) All notices required or permitted hereunder shall be in
writing and shall be served on the Parties at the addresses set forth in Section 12.10(b).  Any such notices may


PAGE 36


be sent by (1) a nationally recognized overnight courier, in which case notice shall be deemed delivered three
(3) business days after deposit with such courier, (2) facsimile transmission, in which case notice shall be
deemed delivered upon actual receipt by recipient,  (3) certified mail, return receipt requested, in which case
notice will be deemed delivered three (3) business days after mailing, or (4) hand-delivery, in which case notice
shall be deemed delivered upon actual receipt by recipient.  Copies of notices are for informational purposes
only, and a failure to give or receive copies of any notice shall not be deemed a failure to give notice. Any
notice or other communication required to be given under this Agreement or in connection with the matters
contemplated by it shall be in writing in the English language. The refusal to accept delivery shall constitute
acceptance, and in such event, the date of delivery shall be the date on which delivery was refused.
Notwithstanding anything to the contrary contained herein, in the event that the delivery of any notice, item, or
information, pursuant to the terms hereof, begins the running of a time period during which a Party is obligated
to respond or else have its approval deemed to have been granted or denied, then such notice, item, or
information shall either bear or be accompanied by a cover letter which bears the following legend (in bold and
capital letters): "TIME SENSITIVE REQUEST - RESPONSE REQUIRED WITHIN A FINITE NUMBER OF DAYS."

         12.11    Dispute Resolution.

         (a)      This Agreement is made in Texas and shall be governed by Texas law pursuant to Section 12.08.
                  In relation to any dispute resolution, legal action, or proceedings to enforce this Agreement
                  or arising out of or in connection with this Agreement ("Enforcement Proceedings"), each of the
                  Parties irrevocably agrees to conduct such proceedings in an appropriate federal or state court
                  sitting in Houston, Harris County, Texas, and submits to the exclusive jurisdiction of such
                  courts and waives any objection to Enforcement Proceedings in such courts on the grounds of
                  jurisdiction, venue, or on the grounds that the Enforcement Proceedings have been brought in an
                  inconvenient forum. The prevailing Party in any such Proceedings (specifically excluding the
                  dispute resolution proceedings described in the following subsection) shall be entitled to
                  recover its reasonable attorneys' fees and other fees and expenses from the other Party.

         (b)      The Parties agree that all claims, controversies, and disputes arising out of or relating to
                  this Agreement, or to the breach, termination, interpretation, or validity thereof ("Disputes")
                  shall be handled as follows: The Party initiating the Dispute shall first give written notice
                  of the Dispute to the other Party.  Executives (of each Party) having authority to settle the
                  Dispute shall then meet and negotiate to resolve the Dispute. If such executives fail to meet
                  or are unable to resolve the Dispute within thirty (30) days after the date of the receiving
                  Party's receipt of the notice from the Party initiating the Dispute, the Parties shall endeavor
                  to settle the dispute by mediation under the Mediation Procedure of the CPR Institute for
                  Dispute Resolution ("CPR") in effect on the date of this Agreement. The Parties have agreed
                  that CPR shall select a mediator in any such Dispute, and such person will agree to serve in
                  that capacity and to be available on reasonable notice.  If the foregoing selected individual
                  is or becomes unwilling or unable to serve, CPR shall appoint another mediator. If neither of
                  these two selected individuals is able or willing to serve, the Parties will agree on a
                  substitute with the assistance of CPR. Unless otherwise agreed in writing, the Parties will
                  select a mediator from the CPR Panels of Distinguished Neutrals. Each Party agrees to bear
                  fifty percent (50%) of the mediation costs, including the fees and expenses of the mediator. If
                  the Dispute has not been resolved by mediation within sixty (60) days after the mediator has
                  commenced such mediation, either Party shall be free to file an appropriate action in the
                  courts identified in the prior subsection with respect to such Dispute.

         (c)      Notwithstanding the foregoing, a Party shall be free to seek judicial relief in the courts
                  specified in subsection (a) above, without resort to the dispute resolution procedures of
                  subsection (b) above, if necessary to prevent immediate or irreparable harm.

12.12    No Third Party Beneficiaries.  Nothing in this Agreement shall provide any benefit to any
third party or entitle any third party to any claim, cause of action, remedy, or right of any kind, it being the
intent of the Parties to this Agreement that this Agreement shall not be construed as a third party beneficiary

12.13    Expenses.  Whether or not the transactions contemplated hereby are consummated, and except
as otherwise specifically provided in this Agreement, all costs and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the Party incurring such costs or expenses.
