         C. Mustang is willing to continue as a member of Clydesdale only on the

         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 and Exhibit A to 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 Clydesdale
Partnership 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,


<PAGE>
                                       2


and "INCLUDING" has the meaning of "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. All pronouns and any variations thereof
shall be deemed to refer to the masculine, feminine or neuter, or singular or
plural, forms thereof, 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. References to any other agreement or contact are to such agreement or
contract as amended, modified or supplemented from time to time in accordance
with the terms hereof (if applicable) and thereof. 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

                         REPRESENTATIONS AND WARRANTIES

         El Paso hereby represents and warrants as of the Closing Date, each
Capital Contribution Date, the Syndication Date, the Third Restatement Date and,
with respect to Section 2.16 only, the date of any Offering Materials as
follows:

         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 Clydesdale, Appaloosa, Noric 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

<PAGE>
                                       3


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. The consolidated balance sheet of El Paso and its
consolidated Subsidiaries as at December 31, 2001 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, 2001, there has been no material adverse change
in such condition or operations.

         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

<PAGE>
                                       4


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 file or 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.

                                       5


         2.11. Proceeds. No proceeds of any Advance will be used to extend
credit to others for the purpose of purchasing or carrying Margin Stock.

         2.12 Investment Company; Holding Company. (a) Neither El Paso nor any
El Paso Party is an "investment company" within the meaning of the Investment
Company Act of 1940.

         (b) Neither El Paso nor any El Paso Party is a "holding company" or a
"subsidiary company" of a "holding company" within the meaning of the Public
Utility Holding Company Act of 1935.

         2.13 El Paso Parties. (a) The Mustang El Paso Member is a wholly owned
Subsidiary of El Paso.

         (b) Each Sponsor Subsidiary Member is an El Paso Company.

         (c) None of Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan,
any Sponsor Subsidiary, any Intermediate Holder or any Underlying Business 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, Affiliate Loans and interest on
the A-Loans (including any guarantee by El Paso of El Paso Demand Loans and
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. No Event of Default, Notice Event, Liquidating Event,
Termination Event or Incipient Event has occurred and is continuing.

         2.16. Disclosure. With respect to the Closing Date, the Third
Restatement Date, each Capital Contribution Date, the Syndication Date, each
Acquisition/Accession Date or the date of any Offering Materials (each, a
"RELEVANT DATE"), as the case may be:

         (a) Subject to the Disclosure Qualification, all information that has
     been made available to the Administrative Agent, CXC, the Lenders, the APA
     Purchasers and the Equity Investors (and the members of the Equity
     Investors or their agents (it being agreed that Citibank, N.A. and its
     Affiliates are not agents of the Equity Investors)) by El Paso or any of
     its directors, 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
     transactions contemplated by the Operative Documents, in each case taken as
     a whole and as modified or supplemented from time to time prior to such
     Relevant Date, was complete and correct in all material 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

<PAGE>
                                       6


     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 Administrative Agent,
     CXC, the Lenders, the APA Purchasers and the Equity Investors (and the
     members of the Equity Investors or their agents) prior to such Relevant
     Date in connection with the transactions contemplated by the Operative
     Documents was prepared in accordance with GAAP then in effect (or with
     appropriate reconciliation to such GAAP if required by Applicable Law or
     requested by the Administrative Agent or the Equity Investors) and fairly
     presents the financial condition and results of operations of El Paso
     (subject to year end audit adjustments) as of the dates and for the periods
     applicable thereto, except as otherwise disclosed therein or in the
     footnotes thereto or as otherwise disclosed in writing to the
     Administrative Agent and the Equity Investors.

         (c) All financial projections that were prepared by El Paso or its
     Representatives and made available to the Administrative Agent, CXC, the
     Lenders, the APA 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

     terms of the Sponsor Subsidiary Credit Agreement, the Clydesdale
     Partnership Agreement and the Mustang 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
     Closing Date or the Third Restatement Date except with respect to the

     such Bankruptcy, or (iii) any E&P Participation Agreement or any Production
     Payment Agreement is not, or is asserted by any Counterparty or other party
     thereto not to be, the legal, valid and binding obligation of such
     Counterparty or other party thereto, enforceable in accordance with its
     terms against such Counterparty or other party thereto, including by reason
     of a lack of certainty of contract or subject matter; or

     may be, all of the net economic benefits and rights, and the legal and
     beneficial interest, of the Counterparty to such E&P Participation
     Agreement in the underlying E&P Participation Property, or to assign to
     such Sponsor Subsidiary, Noric or Noric LP, as the case may be, all of the
     rights under the Material E&P Agreements (as defined in such E&P
     Participation Agreement); or

     any E&P Participation Agreement or any Production Payment Agreement with

         (z) Qualification to Do Business. Any failure by any Sponsor
     Subsidiary, Lipizzan, Noric or Noric LP to qualify to do business in any
     state or other jurisdiction in which such Sponsor Subsidiary, Lipizzan,
     Noric or Noric LP, as the case may be, would not be required to qualify to
     do business but for its owning an E&P Asset.

         El Paso hereby agrees that damages arising as a result of any matter
indemnified under Section 3.2(w) or (x) (or under Section 3.2(y) or (z), if any
failure referred to therein directly or indirectly has any of the effects
described in Section 3.2(w) or (x)) relating to an E&P Asset (or a Sponsor
Subsidiary's, Lipizzan's, Noric's or Noric LP's interest in any E&P
Participation Property, any Production Payment or any Subject Interest), or
under Section 3.2(m) resulting from a breach or inaccuracy of a representation
or warranty under Section 4.03 of the Sponsor Subsidiary Credit Agreement in
respect of an E&P Asset (or a Sponsor Subsidiary's, Lipizzan's, Noric's or Noric
LP's interest in any E&P Participation Property, any Production Payment or any
Subject Interest), are difficult to ascertain as at the date hereof and
accordingly El Paso agrees that a reasonable forecast of such damages would be
an amount, determined as at the Liquidation Start Date, equal to the discounted
present value of the Proved Reserves set forth in the most recent Reserve Report
with respect to such E&P Asset (or such Sponsor Subsidiary's, Lipizzan's,
Noric's or Noric LP's interest in such E&P Participation Property, in such
Production Payment or in such Subject Interest) upon which an E&P Borrowing Base
Determination or E&P Borrowing Base Redetermination was made determined using
the standardized methodology prescribed by the Securities and Exchange
Commission for the calculation of the discounted present value of Proved
Reserves for Securities and Exchange Commission reporting purposes (commonly
known as the "PV-10").

         3.3. Survival of Indemnification Obligations. All indemnities provided
for in this Agreement shall survive the Transfer of any Clydesdale Partnership
Interest, any Noric Membership Interest, any Palomino Membership Interest, any
Paso Fino Membership Interest, any Noric LP Partnership Interest, any Lusitano
Membership Interest, any Lipizzan Partnership Interest or any Sponsor Subsidiary
Membership Interest or the liquidation of Clydesdale, Noric, Palomino, Paso
Fino, Noric LP, Lusitano, Lipizzan or any Sponsor Subsidiary. After any such
Transfer or liquidation, the provisions of Section 3.2 shall inure to the
benefit of each Indemnified Person with respect to Indemnified Amounts arising
in respect of the period during which the partner, member or shareholder or
other holder of an Equity Interest (as applicable) who has Transferred its
Clydesdale Partnership Interest, Noric Membership Interest, Palomino Membership
Interest, Paso Fino Membership Interest, Noric LP Partnership Interest, any
Lusitano Membership Interest, any Lipizzan Partnership Interest or Sponsor
Subsidiary Membership Interest (as applicable) was a partner or member of
Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan or any
Sponsor Subsidiary, as applicable (including with respect to actions taken or
omitted to be taken, and events occurring and circumstances existing, during
such period).

         3.4. Limitations on Indemnification Obligations. The indemnities
provided in Section 3.2 shall be subject to the following limitations:

                                       14


         (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 or (iii) any failure by such Person or any other Person
     to comply with any requirement under or pursuant to Section 6111(d) of the
     Code.

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

         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 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:

<PAGE>
                                       15


         (i) the employment of counsel by such Indemnified Person at the expense
     of El Paso has been authorized in writing by El Paso;

         (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 constitute 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 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. Limitation with Respect to Obligations Under Sponsor Subsidiary
Credit Documents. (a) Notwithstanding anything to the contrary contained in this
Agreement or in any other Operative Document, El Paso does not guarantee:

         (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 Sponsor
     Subsidiary Operating Account, the Sponsor Subsidiary Cash Reserve or the
     Noric Holdings IV Cash Reserve (as applicable) any amounts that are
     required to be deposited into the Sponsor Subsidiary Operating Account, the
     Sponsor Subsidiary Cash Reserve or the Noric Holdings IV 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 Sponsor
     Subsidiary Operating Account, the Sponsor Subsidiary Cash Reserve or the
     Noric Holdings IV Cash Reserve (as applicable) to the extent that there are
     funds on deposit in the Sponsor Subsidiary Operating Account, the Sponsor
     Subsidiary Cash Reserve or the Noric Holdings IV 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(c) or Section 5.04(f) of, or the absence of
     any condition that would result in an Event of Default under Section
     6.01(f) of, the Sponsor Subsidiary Credit Agreement.

         (b) 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) 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); 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 Sponsor Subsidiary Operating Account, the Sponsor
Subsidiary Cash Reserve or the Noric Holdings IV Cash Reserve (as applicable)
any amounts that are required to be deposited into the Sponsor Subsidiary
Operating Account, the Sponsor Subsidiary Cash Reserve or the Noric Holdings IV
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 Sponsor
Subsidiary Operating Account, the Sponsor Subsidiary Cash Reserve or the Noric
Holdings IV Cash Reserve (as applicable) to the extent that there are funds on
deposit in the Sponsor Subsidiary Operating Account, the Sponsor Subsidiary Cash
Reserve or the Noric Holdings IV Cash Reserve after payment of all amounts
referred to in Section 3.6(a) that are then owing,

<PAGE>
                                       17


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).

         3.7. Limitation with Respect to Production Payments. El Paso does not
guarantee that the quantity of Hydrocarbons produced from the Subject Lands (as
defined in each Production Payment Agreement) and attributable to the Subject
Interests will be sufficient to satisfy and discharge the Production Payments
and El Paso shall have no liability to indemnify or hold harmless any
Indemnified Person for any such insufficiency in the quantity of Hydrocarbons
produced from the Subject Lands and attributable to the Subject Interests;
provided, however, the foregoing does otherwise restrict or limit any of El
Paso's guarantees, indemnities, representations or other obligations under this
Agreement that are related to the Production Payment Interests, including El
Paso's Obligations under Sections 3.1(d), 3.1(e), 3.2(d), 3.2(e), 3.2(w), 3.2(y)
and 5.4(b)(vi).

         3.8. Waiver of Fiduciary Duty. El Paso hereby agrees that the Class B
Member 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
Clydesdale, Mustang and the members and creditors of Mustang, and shall be fully
indemnified and held harmless in so voting or acting in accordance with this
Section 3.

                                    SECTION 4

                                    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,

<PAGE>
                                       18


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 an SC Lenders), 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 an SC Lender) 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.

         (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").

<PAGE>
                                       19


         (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-8BEN 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.















<PAGE>
                                       20


         (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.

                                   SECTION 5

                                EL PASO COVENANTS

         5.1. Separate Existence. El Paso hereby covenants and agrees that, so
long as Mustang, or its successors and assigns (other than El Paso or any
Subsidiary of El Paso), holds an interest in Clydesdale, El Paso will, and will
cause each of the El Paso Companies (including the El Paso Parties), Clydesdale
(for so long as the Clydesdale General Partner is an El Paso Company and has the
power and authority to manage the business and affairs of Clydesdale) Noric,
Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan 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 Clydesdale, Noric,
     Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan and any Sponsor
     Subsidiary) will maintain their books, financial records and accounts,

         (ii) El Paso and the El Paso Companies (other than Clydesdale, Noric,
     Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan 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 Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano,
     Lipizzan or any Sponsor Subsidiary, as the case may be. (iii) El Paso and
     the El Paso Companies (other than Clydesdale, Noric, Palomino, Paso Fino,
     Noric LP, Lusitano, Lipizzan and any Sponsor Subsidiary), on the one hand,

     functions with the assets, funds, liabilities or business functions of

     Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan and any Sponsor
     Subsidiary) will each observe all requisite corporate procedures and
     formalities, including the holding of periodic and special meetings of

         (v) Each of Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano,

     Partnership Agreement, the Noric Company Agreement, the Palomino Company
     Agreement, the Paso Fino Company Agreement, the Noric LP Partnership
     Agreement, the Lusitano Company Agreement, the Lipizzan Partnership
     Agreement and the Sponsor 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 Clydesdale,
     Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan and any Sponsor
     Subsidiary) will be consensually merged or consolidated with Clydesdale,
     Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan or any Sponsor
     Subsidiary, as the case may be (other than, with respect to Clydesdale,
     Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan 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 Mustang 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 Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano,
     Lipizzan and each Sponsor Subsidiary from El Paso and its other
     Subsidiaries, and that each of Clydesdale, Noric, Palomino, Paso Fino,
     Noric LP, Lusitano, Lipizzan and each Sponsor Subsidiary has separate
     assets and liabilities. Mustang 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 Clydesdale, Noric, Palomino, Paso Fino,
     Noric LP, Lusitano, Lipizzan and any Sponsor Subsidiary), on the one hand,
     and Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan 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 Clydesdale, Noric, Palomino, Paso Fino, Noric
     LP, Lusitano, Lipizzan or any Sponsor Subsidiary, on the one hand, and any
     third parties, on the other hand, will be conducted in the name of
     Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan or
     such Sponsor Subsidiary (as applicable) as an entity separate and distinct
     from El Paso or any El Paso Company (other than Clydesdale, Noric,
     Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan and any Sponsor
     Subsidiary).

         (x) Except as otherwise specified in the Operative Documents, each of
     Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan and
     each Sponsor Subsidiary, on the one hand, will pay its liabilities and
     losses from its respective assets, and El Paso and the El Paso Companies

<PAGE>
                                       22


     Fino, Noric LP, Lusitano, Lipizzan and any Sponsor Subsidiary), on the
     other hand, will pay their liabilities and losses from their respective
     assets.

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

         (xii) Except as otherwise specified in the Operative Documents, each of
     Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan 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 Clydesdale, Noric, Palomino, Paso Fino, Noric
     LP, Lusitano, Lipizzan or any Sponsor Subsidiary, on the one hand, and El
     Paso or any of the El Paso Companies (other than Clydesdale, Noric,
     Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan and any Sponsor
     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
     Clydesdale, Noric, Palomino, Paso Fino, Noric LP, Lusitano, Lipizzan or any
     Sponsor Subsidiary, on the one hand, and El Paso or any of the El Paso
     Companies (other than Clydesdale, Noric, Palomino, Paso Fino, Noric LP,
     Lusitano, Lipizzan 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

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.
