          and revenue distributions to royalty owners, maintaining and
          supporting accounting records of the oil and gas properties owned by
          Calumet and such other accounting services related to the properties
          as requested.

          (b) Additional Services. From time to time after the Effective Date,
     the Parties may, by mutual agreement, identify additional services that
     Spinco will provide to Calumet in accordance with the terms of this
     Agreement (the "Additional Services" and, together with the Initial
     Services, the "Services"). In such case, the Parties shall create an
     Exhibit for each Additional Service setting forth a description of the
     Service, the time period during which the Service will be provided and any
     other terms applicable thereto.

          (c) Services Performed by Others. At its option, Spinco may cause any
     Service it is required to provide hereunder to be provided by another
     member of the Spinco Group or by any other Person that is providing, or may
     from time to time provide, the same or similar services for members of the
     Spinco Group, Plains or Calumet. Spinco shall remain responsible, in
     accordance with the terms of this Agreement, for performance of any Service
     it causes to be so provided by others.

     2.2  Charges and Payment.

          (a) Charges for Services. Subject to Section 2.2(b), Spinco will
     charge Plains, and Plains will pay Spinco, for the costs incurred in
     providing the Services, including (A) allocable salary and wages,
     incentives, paid absences, payroll taxes, payroll additives (insurance
     premiums, social security, health care and retirement benefits and the
     like) and similar expenses and (B) reimbursement of out-of-pocket third
     party costs and expenses.

          (b) Payment Terms. Spinco shall bill Plains monthly for all charges
     pursuant to this Agreement and Plains shall pay Spinco for all Services
     within 30 days after receipt of an invoice therefor. Late payments shall
     bear interest at an annual rate of the prime rate as reported in the Wall
     Street Journal on the date such payment is due plus two percent (2%) per
     annum.

     2.3  General Obligations; Standard of Care.

          (a) Performance Metrics: Spinco. Spinco shall maintain sufficient
     resources to perform its obligations hereunder and shall perform such
     obligations in a commercially reasonable manner. Specific performance
     metrics for Spinco may be set forth in Exhibits referred to herein. Where
     none is set forth, Spinco shall provide Services in accordance with the
     policies, procedures and practices in effect for the provision of similar
     services in support of the operation and maintenance of the properties
     owned by Calumet before the date of this Agreement and shall exercise the
     same care and skill as it exercises in performing similar services
     hereafter for operations conducted by members of the Spinco Group and shall
     not, in situations in which common personnel, equipment or facilities are
     used in performing Services hereunder and such similar Services for members
     of the Spinco Group, favor either Plains or a member of the Spinco Group.

                                        3

<PAGE>

          (b) Performance Metrics: Plains. Specific performance metrics for
     Calumet may be set forth in Exhibits referred to herein. Where none is set
     forth, Calumet shall, in connection with receiving Services, follow the
     policies, procedures and practices in effect before the date of this
     Agreement including providing information and documentation sufficient for
     Spinco to perform the Services as they were performed before the date of
     this Agreement and making available, as reasonably requested by Spinco,
     sufficient resources and timely decisions, approvals and acceptances so
     that Spinco may accomplish its obligations hereunder in a timely manner.

          (c) Transitional Nature of Services; Changes. The Parties acknowledge
     the transitional nature of the Services and that Spinco may make changes
     from time to time in the manner of performing the Services if Spinco is
     making similar changes in performing similar services for members of the
     Spinco Group and if Spinco furnishes to Calumet substantially the same
     notice Spinco shall provide members of the Spinco Group respecting such
     changes.

          (d) Responsibility for Errors; Delays. Spinco's sole responsibility to
     Calumet:

               (i) for errors or omissions in Services, shall be to furnish
          correct information and/or adjustment in the Services, at no
          additional cost or expense to Calumet; provided, Calumet must promptly
          advise Spinco of any such error or omission of which it becomes aware
          after having used Reasonable Efforts to detect any such errors or
          omissions in accordance with the standard of care set forth in Section
          2.3(b); and provided, further, that the responsibility to furnish
          correct information or an adjustment of services at no additional cost
          or expense to Calumet shall not be construed to require Spinco to make
          any payment or incur any Liability for which it is not responsible, or
          with respect to which it is provided indemnity, under Section 2.7; and

               (ii) for failure to deliver any Service because of
          Impracticability, shall be to use Reasonable Efforts, subject to
          Section 2.4(b), to make the Services available and/or to resume
          performing the Services as promptly as reasonably practicable.

          (e) Good Faith Cooperation; Consents. The Parties will use good faith
     efforts to cooperate with each other in all matters relating to the
     provision and receipt of Services. Such cooperation shall include
     exchanging information, providing electronic access to systems used in
     connection with Services to the extent the systems in use are designed and
     configured to permit such access, performing true-ups and adjustments and
     obtaining all consents, licenses, sublicenses or approvals necessary to
     permit each Party to perform its obligations hereunder. The Parties will
     cooperate with each other in making such information available as needed in
     the event of a tax audit or Regulatory Proceeding, whether in the United
     States or any other country.

                                        4

     2.4  Certain Limitations.

     for purposes of supporting the oil and gas operations of Calumet
     substantially in the manner conducted prior to the Effective Date.

          (b) Impracticability. Spinco shall not be required to provide any
     Service to the extent the performance of such Service becomes
     "Impracticable" as a result of a cause or causes outside the reasonable
     control of Spinco, including armed conflict or economic dislocation
     resulting therefrom; embargoes; shortages of labor, production facilities
     or transportation; labor difficulties; civil disorders of any kind; action
     of any civil or military authorities; fires; floods; and accidents or to
     the extent the performance of such Services would require Spinco to violate
     any laws, rules or regulations or would result in the breach of any
     contract.

          (c) Sale, Transfer, Assignment. Calumet may not sell, transfer, assign
     or otherwise use the Services provided hereunder, in whole or in part, for
     the benefit of any Person.

     2.5  Confidentiality.

          (a) Information Subject to Other Obligations. The Parties agree that
     all Information regarding the Services, including, price, costs and methods
     of operation, shall be maintained in confidence and shall be subject to
     Section 9.9 of the Separation Agreement.

          (b) Internal Use; Title, Copies, Return. Plains and Calumet agree
     that:

               (i) all systems, procedures and related materials provided to
          Plains and Calumet by Spinco in connection with the Services are for
          Plains' and Calumet's internal use only and only as related to the
          Services or any of the underlying systems used to provide the
          Services;

               (ii) title to all systems used in performing the Services
          provided hereunder shall remain in Spinco or its third party vendors;
          and

               (iii) upon the termination of any of the Services, Plains and
          Calumet shall return to Spinco, as soon as practicable, any equipment
          or other property of Spinco relating to the Services that are owned or
          leased by it and are or were in Plains' and Calumet's possession or
          control.

          (c) Survival. The Parties' obligations under this Section 2.5 shall
     survive the termination of this Agreement.

     2.6  Term; Early Termination.

          (a) Term. The term of this Agreement shall commence on the date hereof
     and shall remain in effect through the earlier of (i) the date Calumet is

<PAGE>

     of Plains, (ii) the date Calumet transfers all or substantially all of its
     assets to a Person that is not a Subsidiary of Plains, and (iii) the third
     anniversary of the Effective Date or until such earlier time as all
     Services are terminated as provided in this Section. This Agreement shall
     automatically renew at the end of the initial term for successive one-year
     terms unless either Party sets forth in writing its desire to terminate
     this Agreement at least 30 days in advance of such termination.

          (b) Termination by Plains. Calumet may terminate this Agreement either
     with respect to all, or with respect to any one or more, of the Services
     provided hereunder at any time and from time to time, for any reason or no
     reason, by giving written notice to Spinco at least 90 days in advance of
     the effective date of the termination.

          (c) Termination of Less Than all Services. In the event of any
     termination with respect to one or more, but less than all, Services, this
     Agreement shall continue in full force and effect with respect to any
     Services not terminated hereby.

     2.7  Disclaimer, Limitation of Liability and Indemnification.

          (a) Disclaimer. Spinco shall provide the Services with substantially
     the same degree of care as it employs in making the same services available
     for its own operations; provided, however, that Spinco shall not be liable
     to Plains, Calumet or any other Person for any loss, damage or expense that
     may result therefrom or from any change in the manner in which Spinco
     renders such services, so long as Spinco deems such change necessary or
     desirable in the conduct of its own operations. SPINCO DISCLAIMS ALL
     WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
     WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, WITH
     RESPECT TO THE SERVICES. SPINCO MAKES NO REPRESENTATIONS OR WARRANTIES AS
     TO THE QUALITY, SUITABILITY OR ADEQUACY OF THE SERVICES FOR ANY PURPOSE OR
     USE.

          (b) Indemnification of Plains. Spinco and its Subsidiaries shall have
     no Liability to Plains and Calumet with respect to their furnishing any of
     the Services hereunder except for Liabilities arising out of or resulting
     from the gross negligence or willful misconduct occurring after the
     Effective Date of Spinco or any member of the Spinco Group. Spinco will
     indemnify, defend and hold harmless Plains and Calumet in respect of all
     such Liabilities arising out of or resulting from such gross negligence or
     willful misconduct. Such indemnification obligation shall be a Liability of
     Spinco for purposes of the Separation Agreement and the provisions of
     Article III of the Separation Agreement with respect to indemnification
     shall govern with respect thereto.

          (c) Indemnification of Spinco. Plains and the other members of the
     Plains Group shall indemnify and hold harmless Spinco and its Subsidiaries
     in respect of all Liabilities arising out of or resulting from Spinco's
     furnishing or failing to furnish the Services to Plains provided for in
     this Agreement, other than Liabilities arising out of or resulting from the
     gross negligence or willful misconduct of Spinco or any other member of the
     Spinco Group. The provisions of this indemnity shall apply only to Losses
     that relate directly to the provision of Services. Such indemnification
     obligation shall be a

                                        6

<PAGE>

     Liability of Plains and Calumet (and a Spinco Excluded Liabilities) for
     purposes of the Separation Agreement and the provisions of Article III of
     the Separation Agreement with respect to indemnification shall govern with
     respect thereto.

          (d) Third Party Claims. Any third party claims resulting from or
     arising out of or in connection with this Agreement or the performance of
     or failure to perform the Services will be resolved according to the
     procedures set forth in the Separation Agreement.

          (e) Limitation of Liability. IN NO EVENT SHALL PLAINS OR SPINCO, OR
     ANY MEMBER OF THE PLAINS GROUP OR THE SPINCO GROUP OR THEIR RESPECTIVE
     DIRECTORS, OFFICERS AND EMPLOYEES BE LIABLE TO PLAINS OR SPINCO, OR ANY
     OTHER MEMBER OF THE PLAINS GROUP OR THE SPINCO GROUP FOR ANY SPECIAL,
     CONSEQUENTIAL, INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES OR LOST PROFITS,
     HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE)
     ARISING IN ANY WAY OUT OF THIS AGREEMENT, WHETHER OR NOT SUCH PARTY HAS
     BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; PROVIDED, HOWEVER, THAT
     THE FOREGOING LIMITATIONS SHALL NOT LIMIT EACH PARTY'S INDEMNIFICATION
     OBLIGATIONS FOR LIABILITIES TO THIRD PARTIES AS SET FORTH IN THE SEPARATION
     AGREEMENT OR ANY ANCILLARY AGREEMENT. THE INDEMNIFICATION PROVIDED IN THIS
     ARTICLE II WILL BE APPLICABLE WHETHER OR NOT THE SOLE, JOINT OR
     CONTRIBUTING NEGLIGENCE OF THE INDEMNITEE IS ALLEGED OR PROVEN. THE PARTIES
     AGREE THE PRECEDING SENTENCE IS COMMERCIALLY CONSPICUOUS.

          (f) Subrogation of Rights vis-a-vis Third Party Contractors. If any
     Liability arises from the performance of Services hereunder by a third
     party contractor, Plains and Calumet shall be subrogated to such rights, if
     any, as Spinco may have against such third party contractor with respect to
     the Services provided by such third party contractor to or on behalf of
     Plains or Calumet. Subrogation under this Section 2.7(f) shall not affect
     the obligation of Spinco to perform Services under this Agreement.

          (g) Survival. The Parties' obligations under this Section 2.7 shall
     survive the termination of this Agreement.

     2.8 Representatives. Each Party shall by notice to the other appoint one or
more Representatives to facilitate communications and performance under this
Agreement. Each Party may treat an act of a Representative of the other Party as
being authorized by the other Party without inquiring behind such act or
ascertaining whether such Representative had authority to so act. Each Party may
at any time and from time to time to replace any of its Representatives by
giving notice in writing to the other Party setting forth the name of (i) each
Representative to be replaced and (ii) the replacement, and certifying that the
replacement Representative is authorized to act for the Party giving the notice
in all matters relating to this Agreement (or matters relating to one category
of Services as aforesaid).
