                  (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
                           during the preceding year to the extent not known, all as shown on Schedule
                           3.02(a)(ii).  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.  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
                           3.02(a)(ii).

                  (iii)    Interest.  The Purchase Price shall also be increased by interest on the sum of $129,000,000.00
                           from and including January 1, 2002 through and including the day prior to the Closing
                           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.

         (c)      Closing Statement.  Not later than three (3) Business Days before Closing, Seller shall prepare
                  and deliver to Buyer a statement of the estimated Purchase Price adjustments to be made at
                  Closing pursuant to this Agreement (the "Closing Statement").  The Parties agree that where
                  actual numbers are not available, this Closing Statement will be based upon the prior month's
                  Storage Assets-related financial statements.

                                   ARTICLE IV
                 REPRESENTATIONS AND WARRANTIES OF SELLER

         Seller represents and warrants to Buyer that the matters set forth below in this Article IV are, as of
the date hereof, true and accurate in accordance with their terms.

4.01     Organization and Standing.  Each Seller is a limited partnership duly organized, validly
         existing, and in good standing under the laws of the State of Texas and is duly qualified to transact
         business in the state of Texas.

4.02     No Violations.  The execution, delivery, and performance by Seller of this Agreement and any
         other Transaction Document to which Seller is to be a party and the consummation of the transactions
         contemplated by this Agreement will not:

         (a)      violate any provision of the partnership agreement or certificate of limited partnership of Seller;

         (b)      require Seller to obtain any consent, approval, or waiver from any Governmental Body, except (A)
                  compliance with the HSR Act; or (B) approvals from any Governmental Body (other than pursuant
                  to the HSR Act) or other Persons listed on Schedule 4.02;

         (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

         (d)      violate any Legal Requirement or Order of any Governmental Body against or binding upon Seller or upon
                  the Storage Assets.

4.03     Authority.  Being approved by all of the partners of Seller, Seller has the power and authority
         to enter into and perform this Agreement and the other Transaction Documents to be executed by Seller
         hereunder and to carry out the transactions contemplated herein, and to close the transactions
         contemplated hereby.

4.04     Enforceability.  This Agreement has been, and at the Closing the other Transaction Documents will
         have been, duly executed and delivered by Seller and constitutes or will constitute, legal, valid and
         binding obligations of Seller and enforceable against Seller in accordance with their respective terms,
         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
         a Proceeding in equity or at law).

4.05     Legal Proceedings.  To the Knowledge of Seller and except as set forth on Schedule 4.05, there
         are no outstanding Orders of any Governmental Body against or involving the Storage Assets, and there
         are no Proceedings pending or threatened in writing against or involving the Storage Assets.

4.06     Transferred Contracts.  The Transferred Contracts listed on Schedule 4.06 (except to the extent
         covered under Sections 4.07 and 4.08 as a Permit or a Material Instrument) are, to the Knowledge of
         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
                  expected to become liable if not paid by the applicable Seller or Seller Owner (each, a
                  "Subject Tax") have been duly and timely filed with the appropriate Governmental Body.  Each
                  such Return is true, correct and complete in all material respects.  Each Subject Tax due on
                  each such Return has been timely paid in full and each Subject Tax payable by Seller and each
                  Seller Owner by assessment has been timely paid in the amount assessed.  Seller and each Seller
                  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
                  Subject Taxes, including income, social security, unemployment insurance, sales, excise, use
                  and other Taxes, have been collected or withheld and paid to the proper Governmental Body.
                  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.

PAGE 19


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

8.01     Time and Place.  The closing (the "Closing") of the transactions contemplated by this Agreement
         shall commence at the offices of Seller in Houston, Texas, at 9:00 a.m., Central Standard Time, on a
         mutually agreeable date within three (3) Business Days after all conditions to Closing specified under
         Sections 8.02 and 8.03 have been either met or waived.  The Closing shall be deemed to be effective as
         of the Effective Time.  At Closing, the following events shall occur, each being a condition precedent
         to the others and each being deemed to have occurred simultaneously with the others:

         (a)      Seller will execute and deliver a deed to the Real Property in the form attached hereto as Exhibit
                  8.01(a)-I and will execute and deliver a deed to the water rights described in that certain

         (a)      Seller's Indemnity.  Seller shall indemnify, reimburse, defend, and hold harmless Buyer, its
                  parent company, Affiliates, and Subsidiaries and their respective partners, members, directors,
                  shareholders, officers, employees, agents, attorneys, representatives, contractors, and
                  subcontractors (collectively, the "Buyer Indemnitees") from and against any and all
                  liabilities, claims, losses, strict liability claims, demands, lawsuits, judgments, orders,
                  fines, penalties, damages, expenses (including but not limited to reasonable attorneys' fees
                  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
                  Assets after the Effective Time or any act or omission of Buyer or its Affiliates after the
                  Effective Time in connection with the Storage Assets, (ii) any act or omission of any Hired
                  Employees on and after the Effective Time, (iii) the ownership or operation of the Storage
                  Assets prior to the Effective Time or any act or omission of any Person (including Seller or
                  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.

                                   ARTICLE X
                                   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
         provide the cooperation and information required by this Section 10.07 at its own expense.

                                   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.

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."

         (b)      Addresses.  The addresses and other details of the Parties are:

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.
