                  SECOND AMENDED AND RESTATED EL PASO AGREEMENT


                  SECOND AMENDED AND RESTATED EL PASO AGREEMENT, originally
dated as of June 30, 1999, and amended and restated as of November 22, 1999,
amended as of November 17, 2000 and further amended and restated as of March 29,
2002 (this "AGREEMENT"), by El Paso Corporation, a Delaware corporation ("EL
PASO"), in favor of Red River Investors L.L.C., a Delaware limited liability
company ("RED RIVER"), and the other Indemnified Persons (as defined below).

                  PRELIMINARY STATEMENTS

                  A. El Paso is, through one or more wholly owned subsidiaries,
the owner of 100% of the member interests of Sabine. Sabine is the Trinity Class
A Member and controls Trinity.

                  B. El Paso and Sabine desire Red River to become a Trinity
Class B Member in accordance with the Trinity Company Agreement.

                  C. Red River is willing to become a member of Trinity only on
the condition, among others, that El Paso provides certain assurances set forth
in this Agreement.

                  In consideration of the premises, and intending to be legally
bound by this Agreement, El Paso agrees as follows:

                                    SECTION 1

                      DEFINED TERMS; RULES OF CONSTRUCTION

                  1.1. Definitions.

                  As used in this Agreement, capitalized terms defined in the
preamble and other Sections of this Agreement shall have the meanings set forth
therein and capitalized terms used herein (including in the Preliminary
Statements) but not otherwise defined herein shall have the meanings set forth
in Exhibit A to the Third Amended and Restated Company Agreement of Trinity
River Associates, L.L.C. ("TRINITY") originally dated as of June 29, 1999 and
amended and restated as of June 30, 1999 and November 22, 1999, amended as of
November 17, 2000 and January 31, 2002 and further amended and restated as of
March 29, 2002 by and between Sabine River Investors, L.L.C., a Delaware limited
liability company ("SABINE") and Red River (as amended, amended and restated,
supplemented or otherwise modified from time to time, the "TRINITY COMPANY
AGREEMENT").

                  1.2. Use of Certain Terms.

                  In this Agreement, in the computation of periods of time from
a specified date to a later specified date, the word "FROM" means "FROM AND
INCLUDING" and the words "TO" and "UNTIL" mean "to but excluding". Unless the
context of this Agreement requires otherwise, the plural includes the singular
the singular includes the plural, and "INCLUDING" has the meaning of


<PAGE>


"including without limitation". The words "HEREOF", "HEREIN ", "HEREBY ",
"HEREUNDER ", and other similar terms of this Agreement refer to this Agreement
as a whole and not exclusively to any particular provision of this Agreement.
References to any agreement or contract are to such agreement or contract as
amended, modified or supplemented from time to time in accordance with the terms
hereof and thereof. All pronouns and any variations thereof shall be deemed to
refer to masculine, feminine, or neuter, singular or plural, as the identity of
the Person or Persons may require.

                  1.3. Accounting Terms.

                  All accounting terms not specifically defined herein shall be
construed in accordance with, and certificates of compliance with financial
covenants shall be based upon, GAAP applied consistently.

                  1.4. No Presumption Against Any Party.

                  Neither this Agreement nor any uncertainty or ambiguity herein
shall be construed against any particular party, whether under any rule of
construction or otherwise. On the contrary, this Agreement has been reviewed by
each of the parties and their counsel and shall be construed and interpreted
according to the ordinary meaning of the words used so as to fairly accomplish
the purposes and intentions of all parties hereto.

                  1.5. Headings and References.

                  Section and other headings are for reference only, and shall
not affect the interpretation or meaning of any provision of this Agreement.
Unless otherwise provided, references to Articles, Sections, Schedules, and
Exhibits shall be deemed references to Articles and Sections of, and Schedules
and Exhibits to, this Agreement. Whether or not specified herein or therein,
references to this Agreement and any other Operative Document include this
Agreement and the other Operative Documents as the same may be modified,
amended, restated or supplemented from time to time pursuant to the provisions
hereof or thereof as permitted by the Operative Documents. Whether or not
specified herein, a reference to any law shall mean that law as it may be
amended, modified or supplemented from time to time, and any successor law. A
reference to a Person includes the successors and assigns of such Person, but
such reference shall not increase, decrease or otherwise modify in any way the
provisions in this Agreement governing the assignment of rights and obligations
under or the binding effect of any provision of this Agreement, including
Section 6.6.

                                    SECTION 2

                  El Paso hereby represents and warrants as of the First Closing

with respect to Section 2.16 only, the date of each Information Memorandum as
follows:


                                        2
<PAGE>


                  2.1. Due Formation.

                  El Paso is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware. Each El Paso Party
(other than Trinity or any Sponsor Subsidiary or any Subsidiary of any of the
foregoing) (each such El Paso Party, other than those excluded in the
immediately preceding parenthetical clause, a "RELEVANT EL PASO PARTY") is duly
incorporated or formed, validly existing and in good standing in the
jurisdiction of its incorporation or formation. Each of El Paso and the Relevant
El Paso Parties possesses all corporate, limited liability company or other
applicable Business Entity powers and other authorizations and licenses
necessary to engage in its business and operations as now conducted, the failure
to obtain or maintain which would have a Material Adverse Effect.

                  2.2. Authorization of Operative Documents.

                  The execution, delivery and performance by each of El Paso and
the Relevant El Paso Parties of each Operative Document to which it is a party
are within its applicable Business Entity powers, have been duly authorized by
all necessary corporate, limited liability company or other applicable Business
Entity action, and do not contravene (i) its Organizational Documents or (ii)
any law or material contractual restriction binding on or affecting it.

                  2.3. Governmental Approvals.

                  No authorization or approval or other action by, and no notice
to or filing with, any governmental authority or regulatory body is required for
the due execution, delivery and performance by each of El Paso and the Relevant
El Paso Parties of each Operative Document to which it is a party, except those
necessary to comply with laws, rules, regulations and orders required in the
ordinary course to comply with the ongoing obligations of El Paso under Sections
5.2 and 5.3 and of the Relevant El Paso Parties under the Operative Documents
and to perfect security interests.

                  2.4. Enforceability.

                  Each Operative Document to which any of El Paso and the
Relevant El Paso Parties is a party constitutes the legal, valid and binding
obligations of such Person, enforceable against such Person in accordance with
its terms, except as may be limited by any applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors rights generally
or by general principles of equity.

                  2.5. Accounts.

                  (a) The consolidated balance sheet of El Paso and its
consolidated Subsidiaries as at December 31, 2000 and the related consolidated
statements of income and cash flows of El Paso and its consolidated Subsidiaries
for the fiscal year then ended, reported on by PricewaterhouseCoopers LLP,
independent public accountants, fairly present the consolidated financial
condition of El Paso and its consolidated Subsidiaries as at such date and the
consolidated results of operations of El Paso and its consolidated Subsidiaries
for the period ended on such date, all in accordance with GAAP consistently
applied, and since December 31, 2000 there has been no material adverse change
in such condition or operations.


                                       3
<PAGE>


                  (b) The unaudited consolidated balance sheet of El Paso and
its consolidated Subsidiaries as of September 30, 2001, and the related
consolidated statements of income and cash flows of El Paso and its consolidated
Subsidiaries for the three months then ended, certified by the chief financial
officer of El Paso, fairly present the consolidated results of operations of El
Paso and its consolidated Subsidiaries for the three months then ended, all in
accordance with GAAP consistently applied (except as approved by the chief
financial officer of El Paso and as disclosed therein) and subject to normal
year end audit adjustments.

                  2.6. Compliance with Laws, Etc.

                  Each of El Paso and the Relevant El Paso Parties is in
compliance with all laws, rules, regulations and orders of any governmental
authority applicable to it or its property, except where the failure to so
comply, individually or in the aggregate, would not in the reasonable judgment
of El Paso be expected to result in a Material Adverse Effect.

                  2.7. Litigation.

                  There is no action, suit or proceeding pending, or to the
knowledge of El Paso threatened, against or involving El Paso or any Relevant El
Paso Party or Principal Subsidiary in any court, or before any arbitrator of any
kind, or before or by any governmental body, which, in the reasonable judgment
of El Paso (taking into account the exhaustion of all appeals), would have a
Material Adverse Effect, or which purports to affect the legality, validity,
binding effect or enforceability of any Operative Document.

                  2.8. Taxes.

                  El Paso, each Relevant El Paso Party and each Principal
Subsidiary have duly filed all tax returns required to be filed, and have duly
paid and discharged all taxes, assessments and governmental charges upon it or
against its properties now due and payable, the failure to pay which would have
a Material Adverse Effect, unless and to the extent only that the same are being
contested by any such Person in good faith and by appropriate proceedings. Each
Sponsor Subsidiary that is eligible to be included in the U.S. federal income
tax consolidated return of El Paso will elect to be so included. The Sponsor
Subsidiaries listed on Schedule 2.8 hereto are included in the U.S. federal
income tax consolidated return of El Paso.

                  2.9. Title to Property.

                  El Paso, each Relevant El Paso Party and each Principal
Subsidiary have good title to their respective properties and assets, free and
clear of all mortgages, liens and encumbrances, except for mortgages, liens and
encumbrances (including covenants, restrictions, rights, easements and minor
irregularities in title) which do not materially interfere with the business or
operations of such Person as presently conducted or which are permitted by
Section 5.3(a) and except that no representation or warranty is made with
respect to Margin Stock.

                  2.10. ERISA.

                  (a) No ERISA Termination Event has occurred or is reasonably
expected to occur with respect to any Plan which, with the giving of notice or
lapse of time, or both, would constitute an El Paso Event under clause (g) of
the definition thereof.

                  (b) Each Plan has complied with the applicable provisions of
ERISA and the Code where the failure to so comply would reasonably be expected
to result in an aggregate liability that would exceed 10% of the Net Worth of El
Paso.

                  (c) The statement of assets and liabilities of each Plan and
the statements of changes in fund balance and in financial position, or the
statement of changes in net assets available for plan benefits, for the most
recent plan year for which an accountant s report with respect to such Plan has
been prepared, fairly present the financial condition of such Plan as at such
date and the results of operations of such Plan for the plan year ended on such
date.

                  (d) Neither El Paso nor any ERISA Affiliate has incurred, or
is reasonably expected to incur, any Withdrawal Liability to any Multiemployer
Plan which, when aggregated with all other amounts required to be paid to
Multiemployer Plans in connection with Withdrawal Liability (as of the date of
determination), would exceed 10% of the Net Worth of El Paso.

                  (e) Neither El Paso nor any ERISA Affiliate has received any
notification that any Multiemployer Plan is in reorganization, insolvent or has
been terminated, within the meaning of Title IV of ERISA, and no Multiemployer
Plan is reasonably expected to be in reorganization, to become insolvent or to
be terminated within the meaning of Title IV or ERISA, the effect of which
reorganization, insolvency or termination would be the occurrence of an El Paso
Event under clause (g) of the definition thereof.

                  2.11. Intentionally Omitted.

                  2.12. Investment Company; Holding Company.

                  (a) Neither El Paso nor any El Paso Party is an "investment

                  (c) No Sponsor Subsidiary, Intermediate Holder, or Underlying
Business (other than EPPC, the Sponsor Subsidiary that owns all of the Equity
Interests in EPPC, and any Intermediate Holder relating thereto) is:

                  (i) a Principal Subsidiary, a Restricted Subsidiary, or a
Material Subsidiary; or

                  (ii) directly owned by El Paso.

                  2.14. Priority.

                  The obligations of El Paso and any Affiliate of El Paso under
or in respect of the El Paso Demand Loans and interest on the A-Loans (including
any guarantee by El Paso of El Paso Demand Loans or A-Loans made to Affiliates
of El Paso pursuant to the El Paso Guaranty) rank in priority of payment pari
passu with all other senior unsecured Debt of El Paso or such Affiliate of El
Paso (as applicable).

                  2.15. No Default.

                  With respect to the First Closing Date, the Second Closing

         agents of the Equity Investors)) by El Paso or any of its directors,
         partners, officers, employees, agents, advisors or representatives (all
         of the foregoing, collectively, "REPRESENTATIVES") prior to such
         Relevant Date in connection with the Operative Documents and the

         respects on such Relevant Date and did not on such Relevant Date
         contain any untrue statement of a material fact or omit to state a
         material fact necessary in order to make the statements contained
         therein not misleading in any material respect in light of the
         circumstances under which such statements were made.

                  (b) Any historical financial data provided by El Paso or its
         affiliates or any of their respective Representatives to the Agent,

                  (c) All financial projections that were prepared by El Paso or

         Purchasers and the Equity Investors (and the members of the Equity
         Investors of their agents) prior to such Relevant Date in connection
         with the transactions contemplated by the Operative Documents were
         prepared in good faith based upon assumptions believed by El Paso to be
         reasonable in the circumstances (it being understood that such
         projections are subject to significant uncertainties and contingencies,
         many of which are beyond El Paso's control, and that no assurance can
         be given that the projections will be realized).

                  (d) The financial model for Red River dated as of the Second
         Closing Date attached hereto as Annex I and the supplement thereto
         dated as of the Third Closing Date attached hereto as Annex II (the
         "FINANCIAL Model"), subject to the qualifications and assumptions set
         forth in the Financial Model, (x) contains formulas which are
         consistent with and fairly reflect (i) the allocations provided in the
         Trinity Company Agreement and (ii) the other relevant financial terms
         of the Sponsor Subsidiary Credit Agreement, the Trinity Company
         Agreement and the Red River Company Agreement and (y) sets forth
         computed amounts that fairly reflect the application of such formulae
         to the assumptions contained in the Financial Model.

                  (e) El Paso is not obligated to supplement any information or
         projection or other materials referred to in this Section 2.16 after
         the First Closing Date or the Second Closing Date or the Third Closing
         Date except with respect to the making of the foregoing representations
         and warranties on the Syndication Date and on the date of any
         Information Memorandum and except as otherwise required pursuant to the
         Operative Documents.

         any obligation of Sabine as the Trinity Class A Member to cause Trinity
         to make any Preferred Payment under the Trinity Company Agreement
         (except to the extent that there are funds on deposit in the Trinity
         Operating Account that are available to be applied to such payment at
         the time such payment is due, and then only from such funds) (such

                  3.2. General Indemnities.

                  Subject to Sections 3.4 and 3.7, El Paso agrees to the fullest

         or deemed made:

                           (i) by El Paso in this Agreement or by El Paso or any
                  El Paso Party or other Affiliate of El Paso (or any officer or

                  of any Indemnified Person, any Sponsor Subsidiary or Trinity

                  or any such Affiliate is a party; or

                           (ii) by El Paso or any El Paso Party or any other
                  Affiliate of El Paso (or any officer or other authorized
                  representative thereof) in any written report or certification
                  required hereunder or under any Operative Document to which El
                  Paso, any El Paso Party or any such Affiliate is a party,

                  in each case (A) if but only if such certification,
                  representation or warranty is made as of a specific date, as
                  of the date as of which the facts stated therein were
                  certified, represented or warranted and (B) in all other
                  cases, as of any date or during any period to which such

                  under or in relation to the Operative Documents or the
                  transactions contemplated thereby; and

                           (B) would not have resulted in Indemnified Amounts
                  incurred or realized by or asserted against such Indemnified
                  Person but for their being a party to, or a direct or indirect
                  participant in, or having a relationship described in the
                  definition of "Indemnified Person" to a party to, or a direct

         the assets and liabilities of Trinity or any Sponsor Subsidiary be
         consolidated substantively with the assets and liabilities of El Paso,

         order referred to in clause (i) above; it being agreed that upon the
         occurrence of an event described in clause (i)(y) above which is or
         becomes a final judgment or order, the Indemnified Persons involved
         shall be entitled to recover from El Paso, as liquidated damages for

         amounts recoverable under clause (ii) above or any other provision of
         the Operative Documents), and not as a penalty, an aggregate amount
         equal to the sum of the amount that would be paid to Red River as the
         "Purchase Amount" (as defined in the Purchase Option Agreement) and all
         accrued and unpaid payments owing to Red River pursuant to the Trinity
         Company Agreement through the date of payment in full of such amount in

         or waiver of, to or under any Operative Document (to the extent not
         otherwise reimbursed pursuant to any Operative Document); or

                  (i) Freely Transferable Project Interests. The portion of any
         Contributed Investment purported to be the Freely Transferable Portion

                  (k) Casualty, Etc. Any casualty, theft, personal injury, tort

                  3.4. Limitations on Indemnification Obligations.

                  The indemnities provided in Section 3.2 shall be subject to
the following limitations:

                  (a) Limitation by Law. Such Sections shall be enforced only to
         the maximum extent permitted by Applicable Law.

                  (b) Misconduct, Etc. No Person shall be indemnified or held
         harmless for, and El Paso shall have no liability for or in respect of,
         any Expenses with respect to such Person to the extent caused by or
         resulting from (i) the actual fraud, willful misconduct, bad faith or
         gross negligence of such Person or any of its Related Persons or (ii)
         any inaccuracy in, or breach of, any written certification,
         representation or warranty made by such Person or any of its Related
         Persons in any Operative Document or in any written report or
         certification required hereunder or under any other Operative Document
         (unless and to the extent such inaccuracy or breach is attributable to
         any written information provided by El Paso or its Affiliates), in each
         case under this clause (ii) (A) if, but only if, such certification,
         representation or warranty is made as of a specific date, as of the
         date as of which the facts stated therein were certified, represented
         or warranted and (B) in all other cases, as of any date or during any
         period to which such certification, representation or warranty may be
         applicable.

                  (c) No Duplication. Indemnified Amounts under Section 3.2
         shall be without duplication of any amounts payable under
         indemnification provisions of any other Operative Document or other
         agreement or any amounts actually paid thereunder.

                  3.5. Procedural Requirements.

                  (a) Notice of Claims. Any Indemnified Person that proposes to
assert a right to be indemnified under this Section 3 will, promptly after
receipt of notice of commencement of any action, suit or proceeding against such
Indemnified Person in respect of which a claim is to be made against El Paso
under this Section 3 (an "INDEMNIFIED PROCEEDING"), or the incurrence or
realization of Indemnified Amounts in respect of which a claim is to be made
against El Paso under this Section 3, notify El Paso of the commencement of such
Indemnified Proceeding or of such incurrence or realization, enclosing a copy of
all relevant documents, including all papers served and claims made, but the
omission so to notify El Paso promptly of any such Indemnified Proceeding or
incurrence or realization shall not relieve (i) El Paso from any liability that
it may have to such Indemnified Person under this Section 3 or otherwise,
except, as to El Paso's liability under this Section 3, to the extent, but only
to the extent, that El Paso shall have been prejudiced by such omission or (ii)
any other indemnitor from liability that it may have to any Indemnified Person
under the Operative Documents.

                  (b) Defense of Proceedings. In case any Indemnified Proceeding
shall be brought against any Indemnified Person and it shall notify El Paso of
the commencement thereof, El Paso shall be entitled to participate in, and to
assume the defense of, such Indemnified Proceeding with counsel reasonably
satisfactory to such Indemnified Person, and after notice from El Paso to such
Indemnified Person of El Paso's election so to assume the defense thereof


                                       11
<PAGE>


and the failure by such Indemnified Person to object to such counsel within ten
Business Days following its receipt of such notice, El Paso shall not be liable
to such Indemnified Person for legal or other expenses incurred after such
notice of election to assume such defense except as provided below and except
for the reasonable costs of investigating, monitoring or cooperating in such
defense subsequently incurred by such Indemnified Person reasonably necessary in
connection with the defense thereof. Such Indemnified Person shall have the
right to employ its counsel in any such Indemnified Proceeding, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Person
unless:

                  (i) the employment of counsel by such Indemnified Person at
         the expense of El Paso has been authorized in writing by El Paso (which
         authorization shall not be unreasonably withheld or delayed);

                  (ii) such Indemnified Person shall have reasonably concluded
         in its good faith (which conclusion shall be determinative unless a
         court determines that conclusion was not reached reasonably and in good
         faith) that there is or may be a conflict of interest between El Paso
         and such Indemnified Person in the conduct of the defense of such
         Indemnified Proceeding or that there are or may be one or more
         different or additional defenses, claims, counterclaims, or causes of
         action available to such Indemnified Person (it being agreed that in
         any case referred to in this clause (ii) El Paso shall not have the
         right to direct the defense of such Indemnified Proceeding on behalf of
         the Indemnified Person);

                  (iii) El Paso shall not have employed Jones, Day, Reavis and
         Pogue, or other counsel reasonably acceptable to the Indemnified
         Person, to assume the defense of such Indemnified Proceeding within a
         reasonable time after notice of the commencement thereof (provided,
         however, that this clause shall not be deemed to contribute a waiver of
         any conflict of interest which may arise with respect to any such
         counsel); or

                  (iv) any counsel employed by El Paso shall fail to timely
         commence or maintain the defense of such Indemnified Proceeding,

in each of which cases the fees and expenses of counsel for such Indemnified
Person shall be at the expense of El Paso; provided that without the prior
written consent of such Indemnified Person, El Paso shall not settle or
compromise, or consent to the entry of any judgment in, any pending or
threatened Indemnified Proceeding, unless such settlement, compromise or consent
or related judgment includes an unconditional release of such Indemnified Person
from all liability for Expenses arising out of such claim, action,
investigation, suit or other legal proceeding. No Indemnified Person shall
settle or compromise, or consent to the entry of any judgment in, any pending or
threatened Indemnified Proceeding in respect of which any payment would result
hereunder or under the other Operative Documents without the prior written
consent of El Paso, such consent not to be unreasonably withheld or delayed.
Only one counsel shall be retained by all Indemnified Persons with respect to
any Indemnified Proceeding, unless counsel for any Indemnified Person reasonably
concludes in good faith (which conclusion shall be determinative unless a court
determines that conclusion was not reached reasonably and in good faith) that
there is or may be a conflict of interest between such Indemnified Person and
one or more other Indemnified Persons in the conduct of the defense of such
Indemnified Proceeding or that there


                                       12
<PAGE>


are or may be one or more different or additional defenses, claims,
counterclaims, or causes of action available to such Indemnified Person (it
being agreed that in any case referred to in this sentence such Indemnified
Person may retain separate counsel together with all other Indemnified Persons
subject to the same conflict of interest or sharing such additional defenses,
claims, counterclaims or causes of action).

THE FOREGOING INDEMNITIES SHALL EXPRESSLY INCLUDE ANY INDEMNIFIED AMOUNTS
ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF ANY INDEMNIFIED
PERSON.

                  3.6. Intentionally Omitted.

                  3.7. Limitation with Respect to Obligations Under Sponsor
Credit Documents.

                  (a) Notwithstanding anything to the contrary contained in this
Agreement or in any other Operative Document, neither El Paso nor any Affiliate
of El Paso (other than any Sponsor Subsidiary) guaranties:

                  (i) any payment obligation or deficiency of any Sponsor
         Subsidiary for or in respect of principal or interest under the Sponsor
         Subsidiary Credit Documents (or any instrument or security evidencing
         any obligation in respect thereof); provided, however, that without
         having or incurring any liability itself to make such payment, El Paso
         will exercise its power as direct or indirect owner of all of the
         Equity Interests issued by each Sponsor Subsidiary and each Sponsor
         Subsidiary Member to cause such Sponsor Subsidiary and such Sponsor
         Subsidiary Member to deposit into the Sabine Operating Account or the
         Cash Reserve (as applicable) any amounts that are required to be
         deposited into the Sabine Operating Account or the Cash Reserve
         pursuant to the Sponsor Subsidiary Credit Documents and to direct that
         payment of such items of principal or, interest be made from the Sabine
         Operating Account or the Cash Reserve (as applicable) to the extent
         that there are funds on deposit in the Sabine Operating Account or the
         Cash Reserve that, pursuant to the Operative Documents, are available
         to be applied to such payment at the time such payment is due, but then
         only from such available funds; or

                  (ii) any obligation of any Sponsor Subsidiary under Section
         5.04(a), Section 5.04(b), Section 5.04(d), Section 5.04(e), Section
         5.06(a) or Section 5.07(f) of the Sponsor Subsidiary Credit Agreement.

                  (b) Notwithstanding anything to the contrary contained in this
Agreement or in any other Operative Document, (x) neither El Paso nor any
Affiliate of El Paso (other than any Sponsor Subsidiary) shall have any
liability to indemnify or hold harmless any Indemnified Person for, or to pay,
any Expense arising out of any failure by any Sponsor Subsidiary to pay any
payment obligation or any deficiency of any Sponsor Subsidiary for or in respect
of principal or interest under the Sponsor Subsidiary Credit Documents (or any
instrument or security evidencing any obligation in respect thereof) and (y)
neither El Paso nor any Affiliate of El Paso (other than EPPC) shall have any
liability to indemnify or hold harmless any Indemnified Person for, or to pay,
any Expense arising out of any failure by EPPC to pay, and neither El Paso nor
any such Affiliate (other than EPPC) shall otherwise be liable for, any payment
obligation for or in respect of principal or interest under the EPPC Notes;
provided, however, that without having


                                       13

or incurring any liability itself to make such payment, El Paso will exercise
its power as direct or indirect owner of all of the Equity Interests issued by
each Sponsor Subsidiary and each Sponsor Subsidiary Member to cause such Sponsor
Subsidiary and such Sponsor Subsidiary Member to deposit into the Sabine
Operating Account or the Cash Reserve (as applicable) any amounts that are
required to be deposited into the Sabine Operating Account or the Cash Reserve
pursuant to the Sponsor Subsidiary Credit Documents and to direct that payment
of such items of principal or interest be made from the Sabine Operating Account
or the Cash Reserve (as applicable) to the extent that there are funds on
deposit in the Sabine Operating Account or the Cash Reserve after payment of all
amounts referred to in Section 3.7(a) that are then owing, which funds, pursuant
to the Operative Documents, are available to be applied to such payment at the
time such payment is due, but then only from such available funds.

                  (c) The foregoing clauses (a) and (b) are not intended to
limit any claim under this Agreement (including this Section 3) that is
measured, in whole or in part, by reference to the payment obligations of the
Sponsor Subsidiaries under the Sponsor Subsidiary Credit Documents (it being
understood, for example, that although this Agreement does not constitute a
direct or indirect guaranty of the principal or interest on the Advances, if a
Sponsor Subsidiary breaches the covenant as to Indebtedness under Section
5.09(b) of the Sponsor Subsidiary Credit Agreement and as a result there is
deficiency with respect to the payment of the Advances, a claim may be made
hereunder against El Paso for such deficiency, the damages for which claim may
be measured by the amount of such deficiency).

                  3.8. Waiver of Fiduciary Duty.

                  El Paso hereby agrees that the Independent Manager (as defined
in each Sponsor Subsidiary Company Agreement) of each Sponsor Subsidiary shall
not be bound by a fiduciary duty to act in the best interests of such Sponsor
Subsidiary or any holder of any interest therein, but shall be entitled to vote
in a manner and to take actions which it shall determine, in its sole
discretion, to be in the best interests of Trinity, Red River and the members
and creditors of Red River, and shall be fully indemnified and held harmless in
so voting or acting in accordance with this Section 3.

                                    PAYMENTS

                  4.1. Payments.

                  All payments to be made by El Paso under Section 3 shall be
paid by El Paso within two Business Days following demand therefor, accompanied,
as may be appropriate in the context, by supporting documentation in reasonable
detail. Payment shall be made to the bank account or at another location as such
Indemnified Person shall designate in writing or as is expressly required under
any Operative Document the obligations under which are the subject of any such
payment, not later than 10:00 AM (New York time) on the date for such payment in
immediately available funds.

                  4.2. Taxes.

                  (a) Any and all payments by El Paso hereunder to each
Indemnified Person shall be made, in accordance with Section 4.1, free and clear
of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding all taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, imposed by the
jurisdiction under the laws of which such Indemnified Person is organized,
domiciled, resident or doing business, or any political subdivision thereof or
by any jurisdiction in which such Indemnified Person holds any interest in
connection with this Agreement or any other Operative Document (including,
without limitation, in the case of each lender or APA Purchaser or CXC, the
jurisdiction of such Person's lending or funding office) or any political
subdivision thereof, other than by any jurisdiction with which the Indemnified
Person's connection arises solely from having executed, delivered or performed
obligations or received a payment under, or enforced, this Agreement or any
other Operative Document (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "TAXES"). If El Paso shall be required by Applicable Law to deduct any Taxes
from or in respect of any sum payable hereunder to any Indemnified Person, (i)
the sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 4.2) such Indemnified Person receives an amount equal to the
sum it would have received had no such deductions been made, (ii) El Paso shall
make or cause to be made such deductions and (iii) El Paso shall pay or cause to
be paid the full amount deducted to the relevant taxation authority or other
authority in accordance with Applicable Law, provided that El Paso shall not be
required to pay any additional amount (and shall be relieved of any liability
with respect thereto) pursuant to this Section 4.2 (a) to any Indemnified Person
that either (A) on the date such Person became an Indemnified Person hereunder,
(I) was not entitled to submit a U.S. Internal Revenue Service form W-8BEN
(relating to such Indemnified Person, and entitling it to a complete exemption
from United States withholding taxes on all amounts to be received by such
Indemnified Person pursuant to this Agreement) or any applicable successor form
to similar effect or a U.S. Internal Revenue Service form W-8ECI (relating to
all amounts to be received by such Indemnified Person pursuant to this
Agreement) or any applicable successor form to similar effect and (II) was not a
United States person (as such term is defined in Section 7701(a)(30) of the
Code) or (B) has failed to submit any form or certificate that it was required
to file or provide pursuant to Section 4.2 (d) and is entitled to file or give,
as applicable, under Applicable Law, provided further that should an Indemnified
Person become subject to Taxes because of its failure to deliver a form required
hereunder, El Paso shall take such steps as such Indemnified Person shall
reasonably request to assist such Indemnified Person to recover such Taxes, and
provided further that each Indemnified Person (other than CXC), with respect to
itself, agrees to indemnify and hold harmless El Paso from any taxes, penalties,
interest or other expenses, costs and losses incurred or payable by El Paso as a
result of the failure of El Paso to comply with its obligations under Section
4.2(a)(ii) or (iii) in reliance on any form or certificate provided to it by
such Indemnified Person pursuant to this Section 4.2. If any Indemnified Person
(other than CXC) receives a net credit or refund in respect of such Taxes or
amounts so paid by El Paso, it shall promptly notify El Paso of such net credit
or refund and shall promptly pay such net credit or refund to El Paso, provided
that El Paso agrees to return such net credit or refund if the Indemnified
Person to which such net credit or refund is applicable is required to repay it.


                                       15

                  (b) In addition, El Paso agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made by El Paso hereunder or from
the execution, delivery or performance of, or otherwise with respect to, this
Agreement (hereinafter referred to as "OTHER TAXES").

                  (c) El Paso will indemnify each Indemnified Person for the
full amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section
4.2) paid by such Indemnified Person and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto except as a
result of the gross negligence (which shall in any event include the failure of
such Indemnified Person to provide to El Paso any form or certificate that it
was required to provide pursuant to subsection (d) below) or willful misconduct
of such Indemnified Person, whether or not such Taxes or Other Taxes were
correctly or legally asserted. This indemnification shall be made within 30 days
from the date such Indemnified Person makes written demand therefor.

                  (d) On or prior to the date on which each Indemnified Person
organized under the laws of a jurisdiction outside the United States becomes an
Indemnified Person hereunder, such Indemnified Person shall provide El Paso with
U.S. Internal Revenue Service form W-BEN or W-8ECI, as appropriate, or any
successor form prescribed by the U.S. Internal Revenue Service, certifying that
such Indemnified Person is fully exempt from United States withholding taxes
with respect to all payments to be made to such Indemnified Person hereunder, or
other documents satisfactory to El Paso indicating that all payments to be made
to such Indemnified Person hereunder are fully exempt from such taxes.
Thereafter and from time to time (but only so long as such Indemnified Person
remains lawfully able to do so), each such Indemnified Person shall submit to El
Paso such additional duly completed and signed copies of one or the other of
such Forms (or such successor Forms as shall be adopted from time to time by the
relevant United States taxing authorities) as may be (i) notified by El Paso to
such Indemnified Person and (ii) required under then-current United States law
or regulations to avoid United States withholding taxes on payments in respect
of all amounts to be received by such Indemnified Person pursuant to this
Agreement. Upon the request of El Paso from time to time, each Indemnified
Person that is a United States person (as such term is defined in Section
7701(a)(30) of the Code) shall submit to El Paso a certificate to the effect
that it is such a United States person. If any Indemnified Person determines, as
a result of any change in Applicable Law, or in any official application or
interpretation thereof, that it is unable to submit to El Paso any form or
certificate that such Indemnified Person is obligated to submit pursuant to this
subsection (d), or that such Indemnified Person is required to withdraw or
cancel any such form or certificate previously submitted, such Indemnified
Person shall promptly notify El Paso of such fact.

                  (e) Any Indemnified Person claiming any additional amounts
payable pursuant to this Section 4.2 shall use its best efforts (consistent with
its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its lending or funding office if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts
which may thereafter accrue and would not, in the reasonable judgment of such
Indemnified Person, be otherwise disadvantageous to such Indemnified Person.

                  (f) Without prejudice to the survival of any other agreement
of El Paso hereunder, the agreements and obligations of El Paso and each
Indemnified Person contained in this Section 4.2 shall survive the payment in
full of principal and interest owing under the Sponsor Subsidiary Credit
Agreement.

                  (g) Any other provision of this Agreement to the contrary
notwithstanding, any amounts which are payable by El Paso under this Section 4.2
shall not be payable under Section 3.

                                EL PASO COVENANTS

                  5.1. Separate Existence.

                  El Paso hereby covenants and agrees that, so long as Red
River, or its successors and assigns (other than El Paso or any Subsidiary of El
Paso), holds an interest in Trinity, El Paso will, and will cause each of the El
Paso Companies (including the El Paso Parties), Trinity (for so long as the
Trinity Class A Member is an El Paso Company and has the power and authority to
manage the business and affairs of Trinity) and each Sponsor Subsidiary, to
comply with the following undertakings (except for such non-compliance that, in
the aggregate, is not material):

                  (i) El Paso and the El Paso Companies (other than Trinity and
         any Sponsor Subsidiary) will maintain their books, financial records
         and accounts, including checking and other bank accounts and custodian
         and other securities safekeeping accounts, separate and distinct from
         those of Trinity or any Sponsor Subsidiary, as the case may be.

                  (ii) El Paso and the El Paso Companies (other than Trinity and
         any Sponsor Subsidiary) will maintain their books, financial records
         and accounts (including inter-entity transaction accounts) in a manner
         so that it will not be difficult or costly to segregate, ascertain or
         otherwise identify their assets and liabilities separate and distinct
         from the assets and liabilities of Trinity or any Sponsor Subsidiary,
         as the case may be.

                  (iii) El Paso and the El Paso Companies (other than Trinity
         and any Sponsor Subsidiary) on the one hand, will not commingle any of
         their assets, funds, liabilities or business functions with the assets,
         funds, liabilities or business functions of Trinity or any Sponsor
         Subsidiary, as the case may be, on the other hand.

                  (iv) El Paso and the El Paso Companies (other than Trinity and
         any Sponsor Subsidiary) will each observe all requisite corporate
         procedures and formalities, including the holding of periodic and
         special meetings of shareholders and boards of directors, the
         recordation and maintenance of minutes of such meetings, and the
         recordation and maintenance of resolutions adopted at such meetings.

                  (v) Each of Trinity and the Sponsor Subsidiaries will observe
         all requisite organizational procedures and formalities, including the
         holding of meetings of members and boards of managers as required by
         the Trinity Company Agreement and the Sponsor


                                       17
<PAGE>


         Subsidiary Company Agreements, as applicable, the recordation and
         maintenance of minutes of such meetings, and the recordation of and
         maintenance of resolutions adopted at such meetings.

                  (vi) None of El Paso and the El Paso Companies (other than
         Trinity and any Sponsor Subsidiary) will be consensually merged or
         consolidated with Trinity or any Sponsor Subsidiary, as the case may be
         (other than, with respect to Trinity and any Sponsor Subsidiary, for
         financial reporting purposes, and with respect to any Sponsor
         Subsidiary, for tax purposes). None of El Paso and the El Paso
         Companies will be consensually merged or consolidated with Red River
         for any purpose.

                  (vii) El Paso will include in its consolidated financial
         statements footnotes that clearly disclose, among other things, the
         separate existence and identity of Trinity and each Sponsor Subsidiary
         from El Paso and its other Subsidiaries, and that each of Trinity and
         the Sponsor Subsidiaries has separate assets and liabilities. Red River
         will not be consolidated with El Paso for the purposes of El Paso's
         consolidated financial statements.

                  (viii) All transactions, agreements and dealings between El
         Paso and the El Paso Companies (other than Trinity and any Sponsor
         Subsidiary), on the one hand, and Trinity or any Sponsor Subsidiary, as
         the case may be, on the other hand (including transactions, agreements
         and dealings pursuant to which the assets or property of one is used or
         to be used by the other), will reflect the separate identity and legal
         existence of each entity.

                  (ix) Transactions between Trinity or any Sponsor Subsidiary,
         on the one hand, and any third parties, on the other hand, will be
         conducted in the name of Trinity or such Sponsor Subsidiary (as
         applicable) as an entity separate and distinct from El Paso or any El
         Paso Company (other than Trinity and any Sponsor Subsidiary).

                  (x) Except as otherwise specified in the Operative Documents,
         each of Trinity and the Sponsor Subsidiaries, on the one hand, will pay
         its liabilities and losses from its respective assets, and El Paso and
         the El Paso Companies (other than Trinity and any Sponsor Subsidiary),
         on the other hand, will pay their liabilities and losses from their
         respective assets.

                  (xi) Representatives and agents of Trinity or any Sponsor
         Subsidiary (whether or not they are "loaned" employees of El Paso or
         any El Paso Company (other than Trinity and the Sponsor Subsidiaries))
         will, when purporting to act on behalf of Trinity or any Sponsor
         Subsidiary (as applicable), hold themselves out to third parties as
         being representatives or agents, as the case may be, of Trinity or such
         Sponsor Subsidiary (as applicable), and will utilize business cards,
         letterhead, purchase orders, invoices and the like of Trinity or such
         Sponsor Subsidiary (as applicable).

                  (xii) Each of Trinity and the Sponsor Subsidiaries will
         compensate all consultants, independent contractors and agents from its
         own funds for services provided to it by such consultants, independent
         contractors and agents.

                  (xiii) To the extent that Trinity or any Sponsor Subsidiary,
         on the one hand, and El Paso or any of the El Paso Companies (other
         than Trinity and any Sponsor


                                       18
<PAGE>


         Subsidiary), on the other hand, jointly contract or do business with
         vendors or service providers or share overhead expenses, the costs and
         expenses incurred in so doing will be fairly and nonarbitrarily
         allocated between or among such entities, with the result that each
         such entity bears its fair share of all such costs and expenses. To the
         extent that Trinity or any Sponsor Subsidiary, on the one hand, and El
         Paso or any of the El Paso Companies (other than Trinity and any
         Sponsor Subsidiary), on the other hand, contracts or does business with
         vendors or service providers where the goods or services are wholly or
         partially for the benefit of the other, then the costs incurred in so
         doing will be fairly and nonarbitrarily allocated to the entity for
         whose benefit the goods or services are provided, with the result that
         each such entity bears its fair share of all such costs, except to the
         extent otherwise provided in the Operative Documents.

                  (xiv) Each of Trinity and the Sponsor Subsidiaries will have
         annual financial statements prepared in accordance with GAAP, separate
         from El Paso and the El Paso Companies (other than Trinity and any
         Sponsor Subsidiary), provided that El Paso may consolidate Trinity and
         any Sponsor Subsidiary for El Paso's financial reporting purposes.

                  (xv) None of El Paso and the El Paso Companies (other than
         Trinity and the Sponsor Subsidiaries) will make any inter-entity loans,
         advances, guarantees, extensions of credit or contributions of capital
         to, from or for the benefit of Trinity or any Sponsor Subsidiary, as
         the case may be, without proper documentation and accounting in
         accordance with GAAP and only in accordance with, or as contemplated
         by, the provisions of the Trinity Company Agreement or the relevant
         Sponsor Subsidiary Company Agreement, as the case may be, and the other
         Operative Documents.

                  (xvi) Trinity will not be included in the consolidated tax
         returns of El Paso and the consolidated El Paso Companies (other than
         Trinity).

                  (xvii) El Paso and the El Paso Companies (other than Trinity
         and the Sponsor Subsidiaries) will not refer to Trinity or any Sponsor
         Subsidiary, as the case may be, as a department or division of El Paso
         or any of the El Paso Companies (other than Trinity and any Sponsor
         Subsidiary) and will not otherwise refer to Trinity or any Sponsor
         Subsidiary, as the case may be in a manner inconsistent with its status
         as a separate and distinct legal entity. In addition, each of Trinity
         and the Sponsor Subsidiaries will hold itself out as separate and
         distinct from El Paso and the El Paso Companies (other than Trinity and
         the Sponsor Subsidiaries).

                  (xviii) El Paso shall cause Lord Securities to be elected as
         an independent manager of each Sponsor Subsidiary pursuant to the terms
         of each Sponsor Subsidiary Company Agreement at each election of the
         Board of Managers of such Sponsor Subsidiary.

                  (xix) El Paso and the El Paso Companies (other than Trinity
         and Sabine) will not hold out the credit of either Trinity or Sabine as
         being available to satisfy the obligations of El Paso or the El Paso
         Companies (other than Trinity and Sabine, respectively).


                                       19
<PAGE>


                  (xx) El Paso and the El Paso Companies (other than Trinity and
         Sabine) will not acquire the obligations or securities of Trinity or
         Sabine (except as contemplated by or permitted under the Operative
         Documents).

                  (xxi) El Paso and the El Paso Companies (other than Trinity
         and Sabine) will not use stationery, invoices, and checks bearing the
         name of either Trinity or Sabine.

                  (xxii) El Paso and the El Paso Companies (other than Trinity
         and Sabine) will not pledge their respective assets for the benefit of
         Trinity or Sabine (except as contemplated by or permitted under the
         Operative Documents).

                  (xxiii) El Paso and the El Paso Companies (other than Trinity
         and Sabine) will correct any known misunderstanding regarding their
         respective identities as separate from the identity of each of Trinity
         and Sabine.

                  (xxiv) None of El Paso and the El Paso Companies (other than
         Trinity and Sabine) will use the separate existence of Trinity or
         Sabine to abuse creditors or to perpetrate a fraud, injury, or
         injustice on creditors.

                  (xxv) All transactions between El Paso and the El Paso
         Companies (other than Trinity and Sabine), on the one hand, and each of
         Trinity and Sabine, on the other, are, and will be, duly authorized and
         documented, and recorded accurately in the appropriate books and
         records of such entities. All such transactions will be made in good
         faith and without any intent to hinder, delay, or defraud creditors.

                  (xxvi) No El Paso Company (including Trinity and Sabine) has
         entered into the transactions contemplated by this Agreement or any
         Operative Document to which it is a party in contemplation of
         insolvency or with a design to prefer one or more creditors of such
         Person to the exclusion in whole or in part of others in violation of
         Applicable Law or with an intent to hinder, delay or defraud any of its
         creditors.

                  (xxvii) The assets of each El Paso Company (including Trinity
         and Sabine) are, as of the date hereof, intended to be sufficient to
         pay the ongoing business expenses of each such respective entity as
         they are incurred and to discharge all of their respective liabilities.

                  (xxviii) El Paso shall cause the Sponsor Subsidiary Members to
         appoint a Sponsor Subsidiary Liquidator in compliance with, and to the
         extent required by, Section 11.9 of each Sponsor Subsidiary Company
         Agreement.

                  5.2. Affirmative Covenants.

                  El Paso hereby covenants and agrees that, until the Collection
Date, it will:

                  (a) Preservation of Corporate Existence, Etc. Preserve and
         maintain, and cause each Relevant El Paso Party and each Principal
         Subsidiary to preserve and maintain, its corporate existence, rights
         (organizational and statutory) and material franchises, except in the
         case of each such Person as otherwise permitted by


                                       20
<PAGE>


         Section 5.3(d) or 5.3(e); provided, however, that nothing herein shall
         prevent any change in Business Entity form of El Paso or any Principal
         Subsidiary.

                  (b) Compliance with Laws, Etc. Comply, and cause each Relevant
         El Paso Party and each Principal Subsidiary to comply, in all material
         respects with all Applicable Laws (including, without limitation, all
         environmental laws and laws requiring payment of all taxes, assessments
         and governmental charges imposed upon it or upon its property except to
         the extent contested in good faith by appropriate proceedings) the
         failure to comply with which would have a Material Adverse Effect.

                  (c) Visitation Rights. At any reasonable time and from time to
         time, permit Red River, the Agent, the Collateral Agent, the Equity
         Investors and the Surety (as such terms are defined in the Red River
         Credit Agreement) or any agents or representatives thereof, to examine
         and make copies of and abstracts from the records and books of account
         of, and visit the properties of El Paso or any Relevant El Paso Party

                  El Paso will not, and will not permit any Material Subsidiary
to, enter into any agreement or understanding (a) pursuant to which any
non-equity interest claim El Paso may have against any Material Subsidiary would
be subordinate in any manner to the payment of any other obligation of such
Material Subsidiary (other than waivers or subordination of subrogation,
contribution or similar rights under Guaranties and similar agreements) or (b)
that by its terms limits or restricts the ability of such Material Subsidiary to
make funds available to El Paso (whether by dividend or other distribution, by
replacement of any inter-company advance or otherwise) if, in any such case
referred to in this Section 5.5, there is, at the time any such agreement is
entered into, a reasonable likelihood that all such agreements and
understandings, considered together, would materially and adversely affect the
ability of El Paso to meet its obligations as they become due.

remedies provided by Applicable Law.

                  6.4. Waiver of Jury Trial.

of or relating to this Agreement (such claims and causes of action,
collectively, being "PERMITTED CLAIMS"), and El Paso hereby irrevocably agrees

or proceeding in any aforementioned court in respect of Permitted Claims. Such
service may be made by delivering a copy of such process to El Paso by courier

Applicable Law.

                  (b) Nothing in this Section 6.5 shall affect the right of any

Applicable Law or affect any right otherwise existing of any Indemnified Person
to bring any action or proceeding against El Paso or its property in the courts
of other jurisdictions or (ii) shall be deemed to be a general consent to
jurisdiction in any particular court or a general waiver of any defense or a
consent to jurisdiction of the courts expressly referred to in subsection (a)
above in any action or proceeding in respect of any claim or cause of action
other than Permitted Claims..

                  6.6. Assignment.

and by different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement. This agreement may be delivered by
facsimile transmission of the relevant signature pages hereof.

                  6.9. Survival of Representations, Warranties and Indemnities;
Entire Agreement.

                  All representations, warranties and indemnities and
undertakings to pay costs and expenses contained herein or made by or on behalf
of El Paso, as the case may be, in connection herewith or in connection with the
Operative Documents shall survive (a) the execution and delivery of this
Agreement, (b) the completion of the performance by (i) any Sponsor Subsidiary

                  6.10. Severability.

                  Every provision of this Agreement that is prohibited by or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

                  6.11. No Third-Party Beneficiaries.

                  This Agreement is intended for the exclusive benefit of the

                  (a) To the fullest extent permitted under Applicable Law, El
Paso covenants and agrees that its obligations hereunder will be performed
strictly in accordance with the terms of this Agreement, regardless of any
Applicable Law now or hereafter in effect in any jurisdiction affecting the
ability of any El Paso Party to perform its obligations under any Operative
Document or the rights of any Indemnified Person with respect thereto.

                  (b) To the fullest extent permitted under Applicable Law, any
action or actions may be brought hereunder by any Indemnified Person without the
necessity of joining any prior or other Indemnified Person in such action or
actions. To the fullest extent permitted under Applicable Law, the liability of
El Paso under this Agreement shall be irrevocable, absolute and unconditional
irrespective of, and El Paso hereby irrevocably waives any defenses it may now
or hereafter have in any way relating to, any or all of the following:

                  (i) Any change in the time, manner or place of performance, or
         in any other term, of all or any of the Obligations of El Paso or any
         El Paso Party under any other Operative Document or the Sponsor
         Subsidiary Obligations, or any other amendment, supplement or waiver of
         or any consent to departure from any of the Operative Documents,

         or any El Paso Party thereunder or of the Sponsor Subsidiary

         Parties;

                  (iii) Any act or omission of any Indemnified Person or any
         prior or subsequent Indemnified Person hereunder (other than any
         written amendment or waiver of, or


                                       32
<PAGE>


         consent to departure from, this Agreement meeting the requirements of
         Section 6.1 and except to the extent contemplated by Section 3.4);

                  (iv) Any failure of any Indemnified Person to disclose to El
         Paso any information relating to the financial condition, operations,
         properties or prospects of Trinity, any Sponsor Subsidiary, any Red
         River El Paso Member or any Sponsor Subsidiary Member now or in the
         future known to any Indemnified Person (El Paso waiving any duty on the
         part of each Indemnified Person to disclose such information);

                  (v) Any lack of validity or unenforceability of any of the
         Sponsor Subsidiary Obligations or the Sponsor Subsidiary Member
         Obligations;

                  (vi) Any Sponsor Subsidiary Obligation being unenforceable or
         not allowable due to the existence of a Bankruptcy involving any
         Sponsor Subsidiary;

                  (vii) Any Sponsor Subsidiary Member Obligation being
         unenforceable or not allowable due to the existence of a Bankruptcy
         involving any Sponsor Subsidiary Member; or

                  (viii) Any other circumstance (including any statute of
         limitations or any existence of or reliance on any representation by
         any Indemnified Person) that might otherwise constitute a defense
         available to, or a discharge of, any of the El Paso Parties or El Paso
         or a guarantor or indemnitor generally other than payment and
         performance when due.

                  (c) El Paso s obligations under this Agreement shall continue
to be effective or be reinstated, as the case may be, if at any time any payment
by El Paso or any El Paso Party in satisfaction of any of the obligations of El
Paso or any El Paso Party under the Operative Documents, or any Sponsor
Subsidiary Member Obligation is rescinded or must otherwise be returned upon the
insolvency, bankruptcy or reorganization of El Paso or any El Paso Party, or any
Subsidiary of such Person, or otherwise, all as though such payment had not been
made.

                  6.13. Waiver.

                  Subject to the provisions of Section 3, El Paso hereby waives
(to the extent it may do so under Applicable Law) promptness, diligence, and any
notice from any Indemnified Person with respect to any of El Paso s obligations
under this Agreement and any requirement that any Indemnified Person exhaust any
right or take any action against any of the El Paso Parties or any other Person.

                  6.14. Subrogation.

                  Until indefeasible payment in full of (a) El Paso's
obligations hereunder (b) the Sponsor Subsidiary Obligations, and (c) any other
obligations of any other El Paso Party under the Operative Documents, El Paso
hereby waives any rights that it may acquire by way of subrogation hereunder, by
any payment made hereunder or otherwise. If any amount shall be paid to El Paso
on account of such subrogation rights at any time prior to such obligations
having been paid in full, such amount shall be held in trust for the benefit of
the relevant Indemnified


                                       33

Person and shall forthwith be paid to such Indemnified Person to be credited and
applied to any such obligations, whether matured or unmatured, in accordance
