      2.01 RETENTION OF EL PASO. (a) EPPHC hereby engages El Paso to perform the
Services (as defined below) and to provide all employees and any facilities and
equipment not otherwise provided by EPPHC necessary to perform the Services. El

provide any facilities and equipment not otherwise provided by EPPHC, and to
provide all employees necessary to perform the Services.

described on Exhibit 1 hereto as related to EPPHC's business. The Services shall
be provided by El Paso as directed by the officers of EPPHC.

      2.03 EXCLUSION OR ADDITION OF SERVICES. Upon mutual agreement of the
Parties, any particular service may be temporarily or permanently excluded from
or added to the scope of the Services.

      2.04 PERFORMANCE OF SERVICES BY AFFILIATES. The Parties hereby agree that
in discharging its obligations hereunder, El Paso may engage any of its
Affiliates to perform the Services (or any part of the Services) on its behalf
and that the performance of the Services (or any part of the Services) by any
such Affiliate shall be treated as if El Paso performed such Services itself.
Notwithstanding the foregoing and with the exception of Services excluded
pursuant to Section 2.03 above, nothing contained herein shall relieve El Paso
of its obligations hereunder.

      2.05 INTELLECTUAL PROPERTY.

            (a) Any (i) inventions, whether patentable or not, developed or
invented, or (ii) copyrightable material (and the intangible rights of copyright
therein) developed by El Paso, its Affiliates or its or their employees in
connection with the performance of the Services shall be the property of El
Paso; provided, however, that EPPHC shall be granted an irrevocable,
royalty-free, non-exclusive and non-transferable right and license to use such
inventions or material; and further provided, however, that EPPHC shall only be
granted such a right and license to the extent such grant does not conflict
with, or result in a breach, default, or violation of a right or license to use
such inventions or material granted to El Paso by any Person other than an
Affiliate of El Paso. Notwithstanding the foregoing, El Paso will use all
commercially reasonable efforts to grant such right and license to EPPHC.

            (b) EPPHC hereby grants to El Paso and its Affiliates an
irrevocable, royalty-free, non-exclusive and non-transferable right and license
to use, during the term of this Agreement, any intellectual property provided by
EPPHC to El Paso, but only to the extent such use is necessary for the
performance of the Services. El Paso agrees that it and its Affiliates will
utilize such intellectual property solely in connection with the performance of
the Services.

                                  ARTICLE III
                          BOOKS, RECORDS AND REPORTING

      3.01 BOOKS AND RECORDS. El Paso shall maintain accurate books and records
regarding the performance of the Services and its calculation of the
Reimbursement Amount (as defined below), and shall maintain such books and
records for the period required by applicable accounting practices or law.

      3.02 AUDITS. EPPHC shall have the right, upon reasonable notice, and at
all reasonable times during usual business hours, to audit, examine and make
copies of the books and records referred to in Section 3.01. Such right may be
exercised through any agent or employee of EPPHC designated in writing by it or
by an independent public accountant, engineer or attorney so designated by
EPPHC. EPPHC shall bear all costs and expenses incurred in any inspection,
examination or audit. El Paso shall review and respond in a timely manner to any
claims or inquiries made by EPPHC regarding matters revealed by any such
inspection, examination or audit.

                                       3
<PAGE>
      3.03 REPORTS. El Paso shall prepare and deliver to EPPHC any reports
provided for in this Agreement and such other reports as EPPHC may request from
time to time regarding the performance of the Services.

                                   ARTICLE IV
                              REIMBURSEMENT AMOUNT

      4.01 REIMBURSEMENT AMOUNT. Within five (5) days after the end of each
calendar month, El Paso shall charge EPPHC an amount equal to the estimated fees
associated with the Services performed by El Paso on behalf of EPPHC (the
"Reimbursement Amount"). The Reimbursement Amount shall be calculated on a
reasonable basis consistent with El Paso's internal cost systems and shall
include direct and indirect expenses and general and administrative overhead
expenses related to the Services. The Reimbursement Amount shall be revised
periodically to the extent the actual costs incurred are greater or less than
the estimated fees by 10% or more. On or before the Settlement Date, EPPHC shall
pay to El Paso in immediately available funds the full Reimbursement Amount due
by transfer of funds via the cash management accounts.

      4.02 DISPUTED CHARGES. EPPHC MAY, WITHIN ONE (1) YEAR AFTER RECEIPT OF THE
INTERCOMPANY ACCOUNT CHARGE WITH RESPECT TO A REIMBURSEMENT AMOUNT FROM EL PASO,
TAKE WRITTEN EXCEPTION TO SUCH CHARGE, ON THE GROUND THAT THE SAME WAS NOT A
REASONABLE COST INCURRED BY EL PASO IN CONNECTION WITH THE SERVICES. EPPHC SHALL
NEVERTHELESS PAY IN FULL WHEN DUE THE FULL REIMBURSEMENT AMOUNT CHARGED TO EPPHC
BY EL PASO. SUCH PAYMENT SHALL NOT BE DEEMED A WAIVER OF THE RIGHT OF EPPHC TO
RECOUP ANY CONTESTED PORTION OF ANY AMOUNT SO CHARGED. HOWEVER, IF THE AMOUNT AS
TO WHICH SUCH WRITTEN EXCEPTION IS TAKEN, OR ANY PART THEREOF, IS ULTIMATELY
DETERMINED IN ACCORDANCE WITH ARTICLE VIII NOT TO BE A REASONABLE COST INCURRED
BY EL PASO IN CONNECTION WITH ITS PROVIDING THE SERVICES HEREUNDER, SUCH AMOUNT
OR PORTION THEREOF (AS THE CASE MAY BE) SHALL BE REFUNDED BY EL PASO TO EPPHC
TOGETHER WITH INTEREST THEREON AT THE DEFAULT RATE DURING THE PERIOD FROM THE
DATE OF PAYMENT BY EPPHC TO THE DATE OF REFUND BY EL PASO.

      4.03 SET OFF. In the event that El Paso owes EPPHC an amount under any
other agreement between the Parties, then any such amounts shall be aggregated
and EPPHC and El Paso shall discharge their obligations by netting those amounts
against any amounts owed by EPPHC to El Paso under this Agreement. If EPPHC or
El Paso owes the other Party a greater aggregate amount, that Party shall pay to
the other Party the difference between the amounts owed.

                                   ARTICLE V
                                 FORCE MAJEURE

      5.01 FORCE MAJEURE. A Party's obligation under this Agreement shall be
excused when and to the extent its performance of that obligation is prevented
due to Force

                                       4
<PAGE>
Majeure; provided, however, that a Party shall not be excused by Force Majeure
from any obligation to pay money. The Party that is prevented from performing
its obligation by reason of Force Majeure shall promptly notify the other
Parties of that fact and shall exercise due diligence to end its inability to
perform as promptly as practicable. Notwithstanding the foregoing, a Party is
not required to settle any strike, lockout or other labor dispute in which it
may be involved; provided, however, that, in the event of a strike, lockout or
other labor dispute affecting El Paso, El Paso shall use reasonable efforts to
continue to perform all obligations hereunder by utilizing its management
personnel and that of its Affiliates.

                                   ARTICLE VI
            ASSIGNMENTS, SUBCONTRACTS AND PERFORMANCE OF SERVICES

      6.01 ASSIGNMENTS.

            (a) Without the prior consent of El Paso, EPPHC may not sell,
assign, transfer or convey any of its rights, or delegate any of its
obligations, under this Agreement to any Person.

            (b) Without the prior consent of EPPHC, El Paso may not sell,
assign, transfer or convey of any of its rights, or delegate any of its
obligations, under this Agreement to any Person, other than the delegation of
performance of Services to an Affiliate of El Paso as permitted by Section 2.04.

      6.02 EL PASO'S EMPLOYEES. EPPHC shall not be obligated to pay to El Paso's
employees directly any compensation, salaries, wages, bonuses, benefits, social
security taxes, workers' compensation insurance, retirement and insurance
benefits, training and other such expenses.

      6.03 PERFORMANCE OF SERVICES. Subject to the other provisions hereof, El
Paso agrees to use its reasonable efforts to perform all services in a
reasonable, prudent and timely manner.

                                  ARTICLE VII
                           LIMITATION ON LIABILITY

      7.01 LIMITATION OF LIABILITY. In no event shall either El Paso or EPPHC
have any liability to the other for any incidental, indirect, special or
consequential damages, whether or not caused by or resulting from negligence or
breach of obligations hereunder and whether or not informed of the possibility
of the existence of such damages.

      7.02 SUBROGATION OF RIGHTS. In the event any liability arises from the
performance of Services hereunder by a third party contractor, EPPHC shall be
subrogated to such rights, if any, as El Paso may have against such third party
contractor with respect to the Services provided by such third party contractor
to or for the benefit of EPPHC.

                                  ARTICLE VIII
                              DISPUTE RESOLUTION

      8.01 DISPUTES. This Article VIII shall apply to any dispute arising under
or related to this Agreement (whether arising in contract, tort or otherwise,
and whether arising at law or in equity), including (a) any dispute regarding
the construction, interpretation, performance, validity or enforceability of any
provision of this Agreement or whether any Person is in compliance with, or
breach of, any provisions of this Agreement, and (b) the applicability of this
Article VIII to a particular dispute (collectively, a "Dispute"). The provisions
of this Article VIII shall be the exclusive method of resolving Disputes. For
purposes of this Article VIII, each of El Paso and EPPHC shall be a
"Participant".

      8.02 NEGOTIATION TO RESOLVE DISPUTES. If a Dispute arises which is not
resolved in thirty (30) days, the Participants shall attempt to resolve such
Dispute through the following procedure:

            (a) first, an executive officer of El Paso and an executive officer
of EPPHC shall promptly meet (whether by phone or in person) in a good faith
attempt to resolve the Dispute;

            (b) second, if the Dispute is still unresolved after twenty (20)
days following the commencement of the negotiations described in Section
8.02(a), then the chief executive officers of El Paso and EPPHC will promptly
meet (whether by phone or in person) in a good faith attempt to resolve the
Dispute; and

            (c) third, if the Dispute is still unresolved after ten (10) days
following the commencement of the negotiations described in Section 8.02(b),
then any Participant may submit such Dispute to binding arbitration under this
Article VII by notifying the other Participant (an "Arbitration Notice").

      8.03 SELECTION OF ARBITRATOR.

            (a) Any arbitration conducted under this Article VIII shall be heard
by a sole arbitrator (the "Arbitrator") selected in accordance with this Section
8.03. Each Participant and each proposed Arbitrator shall disclose to the other
Participants any business, personal or other relationship or affiliation that
may exist between such Participant and such proposed Arbitrator, and any
Participant may disapprove of such proposed Arbitrator on the basis of such
relationship or affiliation.

            (b) The Participant that submits a Dispute to arbitration shall
designate a proposed Arbitrator in its Arbitration Notice. If any other
Participant objects to such proposed Arbitrator, it may, on or before the tenth
(10th) day following delivery of the Arbitration Notice, notify the other
Participants of such objection. The Participants shall attempt to agree upon a
mutually-acceptable Arbitrator. If they are unable to do so within twenty (20)
days following delivery of the notice described in the immediately-preceding
sentence, any Participant may request the American Arbitration Association
("AAA") to designate the Arbitrator. If the Arbitrator so chosen shall die,
resign or otherwise fail or becomes unable to serve as Arbitrator, a replacement
Arbitrator shall be chosen in accordance with this Section 8.03.

                                       6
<PAGE>
      8.04 CONDUCT OF ARBITRATION. The Arbitrator shall expeditiously (and, if
possible, within ninety (90) days after the Arbitrator's selection) hear and
decide all matters concerning the Dispute. Except as the Participants agree
otherwise, arbitration hearing shall be held in the City of Houston, Texas.
Except as the Participants agree otherwise, the arbitration shall be conducted
in accordance with the then-current Commercial Arbitration Rules of the AAA
(excluding rules governing the payment of arbitration, administrative or other
fees or expenses to the Arbitrator or the AAA), to the extent that such rules do
not conflict with the terms of this Agreement. Except as expressly provided to
the contrary in this Agreement, the Arbitrator shall have the power (a) to
gather such materials, information, testimony and evidence in the manner as it
deems appropriate relevant to the dispute before it (and each Participant will
provide such materials, information, testimony and evidence requested by the
Arbitrator, except to the extent any information so requested is proprietary,
subject to a third-party confidentiality restriction or to an attorney-client or
other privilege) and (b) to grant injunctive relief and enforce specific
performance. If it deems necessary, the Arbitrator may propose to the
Participants that one or more other experts be retained to assist it in
resolving the Dispute. The retention of such other experts shall require the
unanimous consent of the Participants, which shall not be unreasonably withheld.
Each Participant, the Arbitrator and any proposed expert shall disclose to each
other any business, personal or other relationship or affiliation that may exist
between such Participant (or the Arbitrator) and such proposed expert; and any
Participant may disapprove of such proposed expert on the basis of such
relationship or affiliation. The decision of the Arbitrator (which shall be
rendered in writing) shall be final, nonappealable and binding upon the
Participants and may be enforced in any court of competent jurisdiction;
provided that the Participants agree that the Arbitrator and any court enforcing
the award of the Arbitrator shall not have the right or authority to award
punitive or exemplary damages to any Participant. The responsibility for paying
the costs and expenses of the arbitration, including compensation to the
Arbitrator and any experts retained by the Arbitrator, shall be allocated
between the Participants in a manner determined by the Arbitrator to be fair and
reasonable under the circumstances. Each Participant shall be responsible for
the fees and expenses of its respective counsel, consultants and witnesses,
unless the Arbitrator determines that compelling reasons exist for allocating
all or a portion of such costs and expenses in another manner. Any costs or
expenses incurred by a Participant(s) in enforcing any award of the Arbitrator
shall be borne by the Participant challenging the enforcement.

                                   ARTICLE IX
                                   TERMINATION

      9.01 TERMINATION.

            (a) Either El Paso or EPPHC may terminate this Agreement at any time
by giving notice of such termination to the other party. Any such termination
shall become effective thirty (30) days after delivery of such notice, or such
later time (not to exceed the first anniversary of the delivery of such notice)
as may be mutually agreed upon by El Paso and EPPHC.

      9.02 EFFECT OF TERMINATION. If this Agreement is terminated in accordance
with Section 9.01, all rights and obligations under this Agreement shall cease
except for (a) obligations that expressly survive termination of this Agreement;
(b) liabilities and

                                       7
<PAGE>
obligations that have accrued prior to such termination, including the
obligation to pay any amounts that have become due and payable prior to such
termination, and (c) the obligation to pay any portion of the Reimbursement
Amount that has accrued prior to such termination, even if such portion has not
become due and payable at that time.

                                    ARTICLE X

Agreement, failure on the part of a Party to complain of any act of another
Party or to declare another Party in default under this Agreement, irrespective

         2.04 PERFORMANCE OF SERVICES BY AFFILIATES. The Parties hereby agree
that in discharging its obligations hereunder, EPPHC may engage any of its
Affiliates to perform the Services (or any part of the Services) on its behalf
and that the performance of the Services (or any part of the Services) by any
such Affiliate shall be treated as if EPPHC performed such Services itself.
Notwithstanding the foregoing and with the exception of Services excluded
pursuant to Section 2.03 above, nothing contained herein shall relieve EPPHC of
its obligations hereunder.

         2.05 INTELLECTUAL PROPERTY.

               (a) Any (i) inventions, whether patentable or not, developed or
invented, or (ii) copyrightable material (and the intangible rights of copyright
therein) developed by EPPHC, its Affiliates or its or their employees in
connection with the performance of the Services shall be the property of EPPHC;
provided, however, that EPPOG shall be granted an irrevocable, royalty-free,
non-exclusive and non-transferable right and license to use such inventions or
material; and further provided, however, that EPPOG shall only be granted such a
right and license to the extent such grant does not conflict with, or result in
a breach, default, or violation of a right or license to use such inventions or
material granted to EPPHC by any Person other than an Affiliate of EPPHC.
Notwithstanding the foregoing, EPPHC will use all commercially reasonable
efforts to grant such right and license to EPPOG.

               (b) EPPOG hereby grants to EPPHC and its Affiliates an
irrevocable, royalty-free, non-exclusive and non-transferable right and license
to use, during the term of this Agreement, any intellectual property provided by
EPPOG to EPPHC, but only to the extent such use is necessary for the performance
of the Services. EPPHC agrees that it and its Affiliates will utilize such
intellectual property solely in connection with the performance of the Services.

                                   ARTICLE III
                          BOOKS, RECORDS AND REPORTING

         3.01 BOOKS AND RECORDS. EPPHC shall maintain accurate books and records
regarding the performance of the Services and its calculation of the
Reimbursement Amount (as defined below), and shall maintain such books and
records for the period required by applicable accounting practices or law.

         3.02 AUDITS. EPPOG shall have the right, upon reasonable notice, and at
all reasonable times during usual business hours, to audit, examine and make
copies of the books and records referred to in Section 3.01. Such right may be
exercised through any agent or employee of EPPOG designated in writing by it or
by an independent public accountant, engineer or attorney so designated by
EPPOG. EPPOG shall bear all costs and expenses incurred in any inspection,
examination or audit. EPPHC shall review and respond in a timely manner to any
claims or inquiries made by EPPOG regarding matters revealed by any such
inspection, examination or audit.

                                       3
<PAGE>

         3.03 REPORTS. EPPHC shall prepare and deliver to EPPOG any reports
provided for in this Agreement and such other reports as EPPOG may request from
time to time regarding the performance of the Services.

                                   ARTICLE IV
                              REIMBURSEMENT AMOUNT

         4.01 REIMBURSEMENT AMOUNT. Within five (5) days after the end of each
calendar month, EPPHC shall charge EPPOG an amount equal to the estimated fees
associated with the Services performed by EPPHC on behalf of EPPOG (the
"Reimbursement Amount"). The Reimbursement Amount shall be calculated on a
reasonable basis consistent with EPPHC's internal cost systems and shall include
direct and indirect expenses and general and administrative overhead expenses
related to the Services. The Reimbursement Amount shall be revised periodically
to the extent the actual costs incurred are greater or less than the estimated
fees by 10% or more. On or before the Settlement Date, EPPOG shall pay to EPPHC
in immediately available funds the full Reimbursement Amount due by transfer of
funds via the cash management accounts.

         4.02 DISPUTED CHARGES. EPPOG MAY, WITHIN ONE (1) YEAR AFTER RECEIPT OF
THE INTERCOMPANY ACCOUNT CHARGE WITH RESPECT TO A REIMBURSEMENT AMOUNT FROM
EPPHC, TAKE WRITTEN EXCEPTION TO SUCH CHARGE, ON THE GROUND THAT THE SAME WAS
NOT A REASONABLE COST INCURRED BY EPPHC IN CONNECTION WITH THE SERVICES. EPPOG
SHALL NEVERTHELESS PAY IN FULL WHEN DUE THE FULL REIMBURSEMENT AMOUNT CHARGED TO
EPPOG BY EPPHC. SUCH PAYMENT SHALL NOT BE DEEMED A WAIVER OF THE RIGHT OF EPPOG
TO RECOUP ANY CONTESTED PORTION OF ANY AMOUNT SO CHARGED. HOWEVER, IF THE AMOUNT
AS TO WHICH SUCH WRITTEN EXCEPTION IS TAKEN, OR ANY PART THEREOF, IS ULTIMATELY
DETERMINED IN ACCORDANCE WITH ARTICLE VIII NOT TO BE A REASONABLE COST INCURRED
BY EPPHC IN CONNECTION WITH ITS PROVIDING THE SERVICES HEREUNDER, SUCH AMOUNT OR
PORTION THEREOF (AS THE CASE MAY BE) SHALL BE REFUNDED BY EPPHC TO EPPOG
TOGETHER WITH INTEREST THEREON AT THE DEFAULT RATE DURING THE PERIOD FROM THE
DATE OF PAYMENT BY EPPOG TO THE DATE OF REFUND BY EPPHC.

         4.03 SET OFF. In the event that EPPHC owes EPPOG an amount under any
other agreement between the Parties, then any such amounts shall be aggregated
and EPPOG and EPPHC shall discharge their obligations by netting those amounts
against any amounts owed by EPPOG to EPPHC under this Agreement. If EPPOG or
EPPHC owes the other Party a greater aggregate amount, that Party shall pay to
the other Party the difference between the amounts owed.

                                   ARTICLE V
                                 FORCE MAJEURE

         5.01 FORCE MAJEURE. A Party's obligation under this Agreement shall be
excused when and to the extent its performance of that obligation is prevented
due to Force

                                       4
<PAGE>

Majeure; provided, however, that a Party shall not be excused by Force Majeure
from any obligation to pay money. The Party that is prevented from performing
its obligation by reason of Force Majeure shall promptly notify the other
Parties of that fact and shall exercise due diligence to end its inability to
perform as promptly as practicable. Notwithstanding the foregoing, a Party is
not required to settle any strike, lockout or other labor dispute in which it
may be involved; provided, however, that, in the event of a strike, lockout or
other labor dispute affecting EPPHC, EPPHC shall use reasonable efforts to
continue to perform all obligations hereunder by utilizing its management
personnel and that of its Affiliates.

                                   ARTICLE VI
              ASSIGNMENTS, SUBCONTRACTS AND PERFORMANCE OF SERVICES

         6.01 ASSIGNMENTS.

               (a) Without the prior consent of EPPHC, EPPOG may not sell,
assign, transfer or convey any of its rights, or delegate any of its

               (b) Without the prior consent of EPPOG, EPPHC may not sell,
assign, transfer or convey of any of its rights, or delegate any of its
obligations, under this Agreement to any Person, other than the delegation of
performance of Services to an Affiliate of EPPHC as permitted by Section 2.04.

         6.02 EPPHC'S EMPLOYEES. EPPOG shall not be obligated to pay to EPPHC's
employees directly any compensation, salaries, wages, bonuses, benefits, social
security taxes, workers' compensation insurance, retirement and insurance
benefits, training and other such expenses.

         6.03 PERFORMANCE OF SERVICES. Subject to the other provisions hereof,
EPPHC agrees to use its reasonable efforts to perform all services in a
reasonable, prudent and timely manner.

                                   ARTICLE VII
                             LIMITATION ON LIABILITY

         7.01 LIMITATION OF LIABILITY. In no event shall either EPPHC or EPPOG
have any liability to the other for any incidental, indirect, special or
consequential damages, whether or not caused by or resulting from negligence or
breach of obligations hereunder and whether or not informed of the possibility
of the existence of such damages.

         7.02 SUBROGATION OF RIGHTS. In the event any liability arises from the
performance of Services hereunder by a third party contractor, EPPOG shall be
subrogated to such rights, if any, as EPPHC may have against such third party
contractor with respect to the Services provided by such third party contractor
to or for the benefit of EPPOG.

                                  ARTICLE VIII
                               DISPUTE RESOLUTION

         8.01 DISPUTES. This Article VIII shall apply to any dispute arising
under or related to this Agreement (whether arising in contract, tort or
otherwise, and whether arising at law or in equity), including (a) any dispute
regarding the construction, interpretation, performance, validity or
enforceability of any provision of this Agreement or whether any Person is in
compliance with, or breach of, any provisions of this Agreement, and (b) the
applicability of this Article VIII to a particular dispute (collectively, a
"Dispute"). The provisions of this Article VIII shall be the exclusive method of
resolving Disputes. For purposes of this Article VIII, each of EPPHC and EPPOG
shall be a "Participant".

         8.02 NEGOTIATION TO RESOLVE DISPUTES. If a Dispute arises which is not
resolved in thirty (30) days, the Participants shall attempt to resolve such
Dispute through the following procedure:

               (a) first, an executive officer of EPPHC and an executive officer
of EPPOG shall promptly meet (whether by phone or in person) in a good faith
attempt to resolve the Dispute;

               (b) second, if the Dispute is still unresolved after twenty (20)
days following the commencement of the negotiations described in Section
8.02(a), then the chief executive officers of EPPHC and EPPOG will promptly meet
(whether by phone or in person) in a good faith attempt to resolve the Dispute;
and

               (c) third, if the Dispute is still unresolved after ten (10) days
following the commencement of the negotiations described in Section 8.02(b),
then any Participant may submit such Dispute to binding arbitration under this
Article VII by notifying the other Participant (an "Arbitration Notice").

         8.03 SELECTION OF ARBITRATOR.

               (a) Any arbitration conducted under this Article VIII shall be
heard by a sole arbitrator (the "Arbitrator") selected in accordance with this
Section 8.03. Each Participant and each proposed Arbitrator shall disclose to
the other Participants any business, personal or other relationship or
affiliation that may exist between such Participant and such proposed
Arbitrator, and any Participant may disapprove of such proposed Arbitrator on
the basis of such relationship or affiliation.

               (b) The Participant that submits a Dispute to arbitration shall
designate a proposed Arbitrator in its Arbitration Notice. If any other
Participant objects to such proposed Arbitrator, it may, on or before the tenth
(10th) day following delivery of the Arbitration Notice, notify the other
Participants of such objection. The Participants shall attempt to agree upon a
mutually-acceptable Arbitrator. If they are unable to do so within twenty (20)
days following delivery of the notice described in the immediately-preceding
sentence, any Participant may request the American Arbitration Association
("AAA") to designate the Arbitrator. If the Arbitrator so chosen shall die,
resign or otherwise fail or becomes unable to serve as Arbitrator, a replacement
Arbitrator shall be chosen in accordance with this Section 8.03.

         8.04 CONDUCT OF ARBITRATION. The Arbitrator shall expeditiously (and,
if possible, within ninety (90) days after the Arbitrator's selection) hear and
decide all matters concerning the Dispute. Except as the Participants agree
otherwise, arbitration hearing shall be held in the City of Houston, Texas.
Except as the Participants agree otherwise, the arbitration shall be conducted
in accordance with the then-current Commercial Arbitration Rules of the AAA
(excluding rules governing the payment of arbitration, administrative or other
fees or expenses to the Arbitrator or the AAA), to the extent that such rules do
not conflict with the terms of this Agreement. Except as expressly provided to
the contrary in this Agreement, the Arbitrator shall have the power (a) to
gather such materials, information, testimony and evidence in the manner as it
deems appropriate relevant to the dispute before it (and each Participant will
provide such materials, information, testimony and evidence requested by the
Arbitrator, except to the extent any information so requested is proprietary,
subject to a third-party confidentiality restriction or to an attorney-client or
other privilege) and (b) to grant injunctive relief and enforce specific
performance. If it deems necessary, the Arbitrator may propose to the
Participants that one or more other experts be retained to assist it in
resolving the Dispute. The retention of such other experts shall require the
unanimous consent of the Participants, which shall not be unreasonably withheld.
Each Participant, the Arbitrator and any proposed expert shall disclose to each
other any business, personal or other relationship or affiliation that may exist
between such Participant (or the Arbitrator) and such proposed expert; and any
Participant may disapprove of such proposed expert on the basis of such
relationship or affiliation. The decision of the Arbitrator (which shall be
rendered in writing) shall be final, nonappealable and binding upon the
Participants and may be enforced in any court of competent jurisdiction;
provided that the Participants agree that the Arbitrator and any court enforcing
the award of the Arbitrator shall not have the right or authority to award
punitive or exemplary damages to any Participant. The responsibility for paying
the costs and expenses of the arbitration, including compensation to the
Arbitrator and any experts retained by the Arbitrator, shall be allocated
between the Participants in a manner determined by the Arbitrator to be fair and
reasonable under the circumstances. Each Participant shall be responsible for
the fees and expenses of its respective counsel, consultants and witnesses,
unless the Arbitrator determines that compelling reasons exist for allocating
all or a portion of such costs and expenses in another manner. Any costs or
expenses incurred by a Participant(s) in enforcing any award of the Arbitrator
shall be borne by the Participant challenging the enforcement.

                                   ARTICLE IX
                                   TERMINATION

         9.01 TERMINATION.

               (a) Either EPPHC or EPPOG may terminate this Agreement at any
time by giving notice of such termination to the other party. Any such
termination shall become effective thirty (30) days after delivery of such
notice, or such later time (not to exceed the first anniversary of the delivery
of such notice) as may be mutually agreed upon by EPPHC and EPPOG.

         9.02 EFFECT OF TERMINATION. If this Agreement is terminated in
accordance with Section 9.01, all rights and obligations under this Agreement
shall cease except for (a) obligations that expressly survive termination of
this Agreement; (b) liabilities and

                                        7
<PAGE>

obligations that have accrued prior to such termination, including the
obligation to pay any amounts that have become due and payable prior to such
termination, and (c) the obligation to pay any portion of the Reimbursement
Amount that has accrued prior to such termination, even if such portion has not
become due and payable at that time.

                                    ARTICLE X
                               GENERAL PROVISIONS

the entire agreement of the Parties relating to the matters contained herein,
superseding all prior contracts or agreements, whether oral or written, relating
to the matters contained herein.

Agreement, a waiver or consent, express or implied, to or of any breach or
default by any Party in the performance by that Party of its obligations under
this Agreement is not a consent or waiver to or of any other breach or default
in the performance by that Party of the same or any other obligations of that
Party under this Agreement. Except as otherwise provided in this

                                        8
<PAGE>

Agreement, failure on the part of a Party to complain of any act of another
Party or to declare another Party in default under this Agreement, irrespective
of how long that failure continues, does not constitute a waiver by that Party
of its rights with respect to that default until the applicable
statute-of-limitations period has run.

restated only by a written instrument executed by each of the Parties.

SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, EXCLUDING
ANY CONFLICT-OF-LAWS RULE OR PRINCIPLE THAT MIGHT REFER THE CONSTRUCTION OR THE
INTERPRETATION OF THIS AGREEMENT TO THE LAW OF ANOTHER JURISDICTION. If any
provision of this Agreement or the application thereof to any Person or any
circumstance is held invalid or unenforceable to any extent, the remainder of
this Agreement and the application of such provision to other Persons or
circumstances shall not be affected thereby and shall be enforced to the
greatest extent permitted by law.

         10.07 FURTHER ASSURANCES. In connection with this Agreement and the
transactions contemplated hereby, each Party shall execute and deliver any
additional documents and instruments and perform any additional acts that may be
necessary or appropriate to effectuate and perform the provisions of this
Agreement and those transactions.

         10.08 DIRECTLY OR INDIRECTLY. Where any provision of this Agreement
refers to action to be taken by any Party, or which such Party is prohibited
from taking, such provision shall be applicable whether such action is taken
directly or indirectly by such Party, including actions taken by or on behalf of
any Affiliate of such Party.

         10.09 COUNTERPARTS. This Agreement may be executed in counterparts with
the same effect as if each signing party had signed the same document. All
counterparts shall be construed together and shall constitute one and the same
