                                   COVENANTS

      So long as any Secured Obligations shall remain outstanding, each El Paso
Pledgor agrees, unless the Designated Representative shall otherwise consent in
writing, to comply with the following covenants.

      Section 3.1 Inspection Rights; Reports. At any reasonable time from time
to time, upon reasonable notice, each El Paso Pledgor shall (a) permit the
Designated Representative or its designees, agents or representatives thereof,
at their own cost and expense (unless an Event of Default has occurred and is
continuing), and at their own risk, to inspect, and appraise the Collateral, and
perform such other due diligence with respect to the Collateral as the
Designated Representative or its designees, agents or representatives may
reasonably require to confirm the El Paso Pledgors' compliance with the terms of
the Master Settlement Agreement, this Agreement and any other Security
Documents, and (b) provide to the Designated Representative within a reasonable
time such other reports and certificates relating to the Collateral as may be
reasonably requested by the Designated Representative or its designees, agents
or representatives.

      Section 3.2 Title Review and Opinions.

            3.2.1 With respect to the Property that is Oil and Gas Collateral on
the Effective Date (the "Initial Oil and Gas Collateral"), the Settlement Fund,
through its legal counsel, Thompson & Knight, LLP ("T&K"), has conducted a
limited review of the title of the Initial Oil and Gas Collateral. Based on that
review, the Settlement Fund, through T&K, has in good faith endeavored to
provide the El Paso Pledgors on or prior to the Effective Date with written
notice of all material liens, encumbrances and other title defects and
exceptions identified by T&K during its review that are not Permitted Liens and
that are objectionable to the Settlement Fund. The applicable El Paso Pledgors
hereby agree to cure such objectionable liens, encumbrances, and other title
defects and exceptions in accordance with the terms of Section 3.9 of this
Agreement.

      The Settlement Fund shall be entitled to title opinions prepared by
counsel reasonably acceptable to the Designated Representative and in form and
substance reasonably satisfactory to the Designated Representative concerning
not less than eighty percent (80%) of the Reported Value of the Initial Oil and
Gas Collateral unless a lesser percentage is otherwise agreed to in writing by
the Designated Representative. The Designated Representative, on behalf of the
Settlement Fund, agrees to cause T&K to deliver all title opinions covering
Initial Oil and Gas

                                       10
<PAGE>

Collateral required by this section to it and the Collateral Agent (with copies
to the applicable El Paso Pledgors) within one-hundred twenty (120) days after
the Effective Date, unless otherwise consented to in writing by the El Paso
Pledgors. Any liens, encumbrances, title defects or exceptions contained in such
title opinions that are not Permitted Liens and that are objectionable to the
Settlement Fund shall be objected to in writing by the Collateral Agent to the
applicable El Paso Pledgor within thirty (30) days after the delivery of the
title opinion covering such Oil and Gas Collateral. Such objectionable liens,
encumbrances, title defects, and exceptions shall be cured by the applicable El
Paso Pledgors in accordance with Section 3.9 hereof.

      The Settlement Fund, through the Collateral Agent, shall have the right at
any time to object in writing to the applicable El Paso Pledgors as to any
liens, encumbrances or other title defects or exceptions on or with respect to
any Initial Oil and Gas Collateral that are not Permitted Liens and that are
either not identified in the title opinions covering such Initial Oil and Gas
Collateral or affect Initial Oil and Gas Collateral for which no title opinion
was given. The El Paso Pledgors shall cure such liens, encumbrances, other title
defects and exceptions in accordance with Section 3.9. Other than the costs,
expenses, and fees incurred by the Settlement Fund for T&K's title review
conducted prior to the Effective Date and the title review and preparation of
title opinions by T&K delivered pursuant to the second subparagraph of this
Section 3.2.1, no El Paso Pledgor shall, unless otherwise agreed to in writing
by that El Paso Pledgor, be responsible for any costs, expenses or fees incurred
by or on behalf of the Collateral Agent, the Designated Representative, or the
Settlement Fund with respect to any title review or the preparation of other
title opinions covering the Initial Oil and Gas Collateral.

            3.2.2 In connection with the substitution or addition of any Oil and
Gas Collateral after the Effective Date (the "Additional Oil and Gas
Collateral"), the Settlement Fund shall be entitled to title opinions prepared
by counsel reasonably acceptable to the Designated Representative addressed to
and in form and substance reasonably satisfactory to the Designated
Representative covering not less than eighty percent (80%) of the Reported Value
of the Additional Oil and Gas Collateral. All title opinions covering Additional
Oil and Gas Collateral shall be delivered to the Designated Representative and
Collateral Agent (with a copy to the appropriate El Paso Pledgors)
simultaneously with the delivery pursuant to Section 4.3 of the Additional
Collateral Certificate covering such Additional Oil and Gas Collateral;
provided, however, that the title opinions covering Additional Oil and Gas
Collateral for which an Additional Collateral Certificate is delivered to the
Collateral Agent within sixty (60) days after the Effective Date may, at the
option of the El Paso Pledgor providing such Additional Oil and Gas Collateral,
be delivered by T&K within one-hundred twenty (120) days after the date on which
the Additional Collateral Certificate has been delivered (unless otherwise
consented to in writing by such El Paso Pledgor) if T&K has been afforded an
opportunity during such sixty (60) day period to conduct a limited review of the
title of such Additional Oil and Gas Collateral consistent with the review it
undertook with respect to the Initial Oil and Gas Collateral.

      As soon as practical, but in any event no later than thirty (30) days
after the date on which each such title opinion covering any compliant
Additional Oil and Gas Collateral is received by the Collateral Agent with
respect to any Additional Oil and Gas Collateral, the Collateral Agent, on
behalf of the Settlement Fund, shall deliver to the applicable El Paso Pledgors
a written list of any liens, encumbrances or other title defects or exceptions
(other than Permitted Liens) with respect to such Additional Oil and Gas
Collateral that are unacceptable to

                                       11
<PAGE>

the Settlement Fund. The El Paso Pledgors shall cure such liens, encumbrances or
other title defects or exceptions in accordance with Section 3.9.

      The Collateral Agent, on behalf of the Settlement Fund, shall have the
right at any time to object to any liens, encumbrances or other title defects or
exceptions on or with respect to any Additional Oil and Gas Collateral that are
not Permitted Liens and that are either not identified in such title opinions or
affect Additional Oil and Gas Collateral for which no title opinion has been
given. The El Paso Pledgors shall cure such liens, encumbrances or other title
defects or exceptions in accordance with Section 3.9.

      Other than the costs, expenses, and fees incurred in the preparation of
the title opinions delivered pursuant to the first subparagraph of this Section
3.2.2, and any title review by T&K within sixty (60) days of the Effective Date
in connection with any Additional Oil and Gas Collateral for which an Additional
Collateral Certificate will be delivered to the Collateral Agent within such
sixty (60) day period, no El Paso Pledgor shall, unless otherwise agreed to in
writing by that El Paso Pledgor, be responsible for any costs, expenses or fees
incurred by or on behalf of the Collateral Agent, the Designated Representative,
or the Settlement Fund with respect to any title review or the preparation of
other title opinions covering Additional Oil and Gas Collateral.

            3.2.3 In connection with the substitution or addition of any Other
Collateral, the Settlement Fund shall be entitled to conduct a review of the
state of the El Paso Pledgors' title to such Other Collateral. Such review shall
include as to Other Collateral constituting real estate, the right to require
the applicable El Paso Pledgors to deliver one or more title commitments and
ultimately title policies covering title to such real property constituting
Other Collateral, together with re-insurance if requested by the Settlement Fund
(through the Designated Representative or Collateral Agent). Any such title
commitments (and ultimately, title policies) shall be (a) issued by the national
office of a title insurance company rated at least A-X or better by the then
current edition of Best's Insurance Reports published by A.M. Best Company, (b)
in an amount at least equal to the Value of such Other Collateral customarily
covered by title insurance (including real property and improvements), and (c)
contain such endorsements, have omitted such standard exceptions, and otherwise
be in a form that is usual and customary in secured lending transactions where
the collateral is of a similar type and quality as such Other Collateral. As
soon as practical, but in any event no later than thirty (30) days after the
completion of such title review (and thirty (30) days after delivery of all
title commitments, if any are required), the Collateral Agent shall deliver to
the applicable El Paso Pledgors a written list of any liens, encumbrances or
other title defects or title exceptions with respect to the Other Collateral
that do not constitute Permitted Liens and that adversely affect such Pledgor's
title to, or the marketability of, the Other Collateral or the Value of such
Other Collateral. The El Paso Pledgors shall cure such liens, encumbrances or
other title defects or title exceptions in accordance with Section 3.9.

      Section 3.3 Compliance with Laws, Etc. Each El Paso Pledgor shall comply,
in all material respects with all Legal Requirements; provided, however, that
nothing in this Section 3.3 shall prevent such El Paso Pledgor, in good faith
and with reasonable diligence, from contesting the validity or application of
any such laws or regulations by appropriate legal proceedings; provided,
however, with respect to any challenge of a violation that might result in

                                       12
<PAGE>

imposition of monetary obligations, adequate reserves in conformity with GAAP
must be provided. Each El Paso Pledgor shall maintain and possess all
authorizations, permits, and licenses that are necessary for the ownership and
operation of the Collateral, except to the extent failure to do so could not
reasonably be expected to have a Material Adverse Effect.

      Section 3.4 Payments. Each El Paso Pledgor shall pay and discharge, before
the same shall become delinquent, (a) all taxes, assessments, and governmental
charges or levies imposed upon it or upon its income or profits or Property that
are attributable to its interest in the Collateral that are material in amount,
prior to the date on which penalties attach thereto, and (b) all lawful claims
that are material in amount which, if unpaid, would by law become a lien upon
the Collateral; provided, however, that such El Paso Pledgor shall not be
required to pay or discharge any such tax, assessment, charge, levy, or claim
which is being contested in good faith and by appropriate proceedings, and with
respect to which reserves in conformity with GAAP have been provided.

      Section 3.5 Maintenance of Collateral. With respect to its interest in the
Collateral, each El Paso Pledgor shall (a) maintain, develop and protect the
Collateral in a good and workmanlike manner and in accordance in all material
respects with all applicable Legal Requirements and, in the case of Oil and Gas
Collateral, as a prudent operator would in accordance with generally accepted
practices in the oil and gas industry applicable to Leases and contracts; (b)
abstain from knowingly or willfully permitting, or where applicable, failing to
cure or cease, the commission of waste or other injury, destruction, or loss of
natural resources, or the violation of any Environmental Law that could
reasonably be expected to be material in nature; and (c) observe and comply with
all of the terms and provisions, express or implied, of the Oil and Gas
Properties in order to keep the Oil and Gas Properties in full force and effect
so long as the Oil and Gas Properties are producing Hydrocarbons in commercial
quantities; and (d) comply in all material respects with all contracts and
agreements applicable to or relating to the Collateral or the production and
sale of Hydrocarbons therefrom; provided, however, that such El Paso Pledgor (i)
shall not be required to perpetuate or renew any Lease that constitutes Oil and
Gas Collateral by payment of delay rentals, drilling of wells, conducting
reworking operations, or conducting seismic operations, (ii) may abandon or
release any Lease that constitutes Oil and Gas Collateral that, in the opinion
of such El Paso Pledgor is uneconomic, or (iii) may pool and unitize Leases that
constitutes Oil and Gas Collateral with third-party Leases.

      Section 3.6 Maintenance of Insurance. Each El Paso Pledgor shall at all
times maintain or cause to be maintained, with financially sound and reputable
insurance companies, insurance for its Property and with respect to all
Collateral consistent with best practices and in such amounts, covering such
risks, in such form and with such deductibles as are customarily carried by
companies of similar size engaged in similar businesses and owning similar
properties in localities where such El Paso Pledgor operates. Upon demand by the
Collateral Agent, any insurance policies covering Collateral shall be endorsed
to provide (a) for payment of losses to the Collateral Agent on behalf of the
Settlement Fund as its interests may appear, (b) that such policies may not be
canceled or reduced or affected in any material manner for any reason without
fifteen (15) days prior notice to Collateral Agent, (c) for any other matters
specified in any applicable Security Document.

                                       13
<PAGE>

      Reimbursement under any liability insurance maintained by the El Paso
Pledgors pursuant to this Section 3.6 may be paid directly to the Person who has
incurred the liability covered by such insurance. With respect to any loss
involving damage to Collateral, each El Paso Pledgor will make or cause to be
made the necessary repairs to or replacements of such Collateral, and any
proceeds of insurance maintained by each El Paso Pledgor pursuant to this
Section 3.6 and paid to the Collateral Agent shall be paid to such El Paso
Pledgor by the Collateral Agent as reimbursement for the costs of such repairs
or replacements as such repairs or replacements are made or acquired.

      Section 3.7 Grant of Liens. As more fully provided for in Paragraphs
8.3(e) and 8.3(f) and Appendix 1.89 of the Master Settlement Agreement, each El
Paso Pledgor shall deliver to the Collateral Agent (a) (i) an executed
non-recourse guaranty (the "Guaranty"), which Guaranty shall be in form and
substance substantially similar to the form of guaranty attached hereto as
Exhibit A-1, (ii) as appropriate, executed deeds of trust or mortgages granting
liens encumbering its interests in Oil and Gas Collateral, which deeds of trust
shall be in form and substance substantially similar to the form of deed of

substance substantially similar to the form of mortgage attached hereto as
Exhibit A-3, and (iii) with respect to any Other Collateral, such executed
Security Documents as the Designated Representative or such El Paso Pledgor may
reasonably require, (b) (i) stand-alone audited financial statements with
accompanying footnotes (or if such El Paso Pledgor does not obtain stand-alone
audited financial statements then unaudited management prepared income
statements and balance sheets) for it as of the close of the immediately
preceding calendar year and unaudited management prepared income statements and
balance sheets for it current through the last day of the immediately preceding
calendar quarter, in each case such financial statements (other than any
unaudited management prepared income statements or balance sheets) having been
prepared in accordance with GAAP, except as is expressly disclosed in such
financial statements or by such El Paso Pledgor in the certificate required
below in clause (b)(iii), applied in a manner consistent with past practice and
fairly presenting, in all material respects, the financial condition of the El
Paso Pledgor, (ii) a schedule listing in detail all assets and liabilities due
to or from any of the other El Paso Releasees, liability for taxes under
Internal Revenue Code Regs., Section 1.1502-6 (or similar state, local or

      Section 3.8 Maintenance of Liens. Each El Paso Pledgor shall promptly cure
any defects in the execution and delivery of the Security Documents as to which
it is a party and this Agreement. Each El Paso Pledgor hereby authorizes the
Collateral Agent to file any initial financing statements, amendments or
continuation statements without the signature of such El Paso Pledgor to the
maximum extent permitted by applicable law, including Section 9-509 of the
Uniform Commercial Code as in effect in the state where the Collateral is
located and the state where such El Paso Pledgor is organized (as the same may
be amended, modified or succeeded), in order to perfect or maintain the
perfection of any lien or security interest granted under any of the Security
Documents. Each El Paso Pledgor will promptly execute and deliver to the
Collateral Agent upon request all such other documents, agreements and
instruments necessary to further evidence and more fully describe the Property
intended as Collateral, or to correct any omissions in the Security Documents,
or to perfect, protect or preserve any liens created pursuant to any of the
Security Documents, or to make any recordings, to file any notices or obtain any
consents, all as may be necessary or appropriate in connection therewith.

      Section 3.9 Title Defects. As to any liens, encumbrances, material title
defects or title exceptions burdening Collateral that are not Permitted Liens,
and that are objected to pursuant to Section 3.2 hereof, each El Paso Pledgor
shall with reasonable dispatch, but in no event more than sixty (60) days after
the date of such objection, either (a) cure such liens, encumbrances, title
defects or title exceptions which are not Permitted Liens, (b) substitute
Properties with no material title defects or exceptions except for Permitted
Liens and which substitute Properties shall have sufficient Value to maintain
the Minimum Collateral Coverage in accordance with the terms of Section 4.1
hereof, or (c) agree with the Designated Representative as to a mutually
acceptable reduced value for such Collateral that takes into account such title
defects or title exceptions.

      Section 3.10 No Liens, Etc. No El Paso Pledgor shall create, assume,
incur, or suffer to exist, any lien on or in respect of any of interest in its
respective Collateral, except that such El Paso Pledgor may create, incur,
assume, and suffer to exist (a) Permitted Liens, and (b) contracts to effect a
Permitted Disposition.

      Section 3.11 Dispositions. Except for Permitted Dispositions, and in
connection with the substitution or release of Collateral provided for in
Article IV, no El Paso Pledgor shall Dispose of any of its interests in the
Collateral.

      Section 3.12 Non-Operated Properties. Notwithstanding anything herein to
the contrary, with respect to any of the covenants in Section 3.1, 3.3 and 3.5
hereof that relate to Oil

                                       15
<PAGE>

and Gas Collateral but for which one of the El Paso Pledgors is not the operator
of record, then such covenant shall be deemed to be satisfied so long as the
such El Paso Pledgor uses reasonable efforts to cause the operator of such Oil
and Gas Collateral to comply with such covenants.

                                   ARTICLE IV.
                SUBSTITUTION, RELEASE, AND ADDITION OF COLLATERAL

      Section 4.1 Right to Substitute Collateral. An El Paso Pledgor may,
subject to the terms of this Article IV, at any time provide to the Collateral
Agent substitute Collateral and in connection therewith obtain a release from
the Collateral Agent as to existing Collateral. To effect a substitution of
Collateral, an El Paso Pledgor shall comply with the obligations set out in
Section 4.3 with respect to the substitute Collateral that will be added, and
the El Paso Pledgor and the Collateral Agent shall comply with the obligations
set out in Section 4.2 with respect to the Collateral to be released.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing, then an El Paso Pledgor may only substitute Collateral pursuant to
this Article IV if such substitution of Collateral shall cure such Event of
Default within the time period provided herein in Section 5.

      Section 4.2 Collateral Release Provisions.

            4.2.1 Any El Paso Pledgor may request from time to time that the
Collateral Agent release, reduce or surrender Collateral, including any Letters
of Credit, if after giving effect to such request and the pledge of any
additional Collateral on such date, the Value of all Collateral exceeds the
Minimum Collateral Coverage and, if a Monetization has been effected, following
such release, the ratio of the aggregate stated amount of Letters of Credit
divided by the Discounted Amount of the Deferred Payments shall be the same or
greater than such ratio immediately prior thereto. Such request shall be made
pursuant to a certificate ("Release Certificate") in form and substance
substantially similar to the instrument attached hereto as Exhibit B-1. The
Value of the Collateral to be released, reduced or surrendered shall not exceed
the difference between (a) the aggregate Value of all Collateral immediately
prior to the date of such release, reduction or surrender and after giving
effect to the pledge of any additional Collateral on such date, and (b) the
Value of Collateral required to maintain the Minimum Collateral Coverage. The
Release Certificate shall be accompanied by execution counterparts of the
instruments to be executed by the Collateral Agent (which instruments shall be
reasonably satisfactory to the Collateral Agent) to effect such release,
reduction or surrender, and if a Monetization has been effected, written
certification addressed to the Collateral Agent, executed by a Responsible
Officer of El Paso Corporation, stating that following such release, the ratio
of the aggregate stated amount of Letters of Credit divided by the Discounted
Amount of the Deferred Payments will be the same or greater than such ratio
immediately prior thereto. Promptly (and in any event within ten (10) Business
Days) after the Collateral Agent's receipt of the Release Certificate, the
Collateral Agent shall execute and deliver to such El Paso Pledgor, at such El
Paso Pledgor's sole cost and expense, all such instruments and take all such
other actions as reasonably requested by such El Paso Pledgor to effect the
release of any liens or security interests held by the Collateral Agent on such
Collateral and the surrender or reduction, as specifically requested, of the
applicable Letters of Credit; provided, however, that if any additional
Collateral is required to be given by the El Paso Settling Parties to maintain
the

                                       16
<PAGE>

Minimum Collateral Coverage (after giving effect to the release, surrender or
reduction requested by such El Paso Pledgor), then the Collateral Agent shall
have no obligation to execute and deliver to such El Paso Pledgor any
instruments or take any other actions to effect the release of any liens or
security interests held by the Collateral Agent on such Collateral and the
surrender or reduction, as specifically requested, of the applicable Letters of
Credit, until all of the requirements set forth herein and in Section 4.3 have
been satisfied.

            4.2.2 Permitted Dispositions

                  (a) Any El Paso Pledgor may consummate one or more Permitted
      Dispositions described in clause (a) and (b) of the definition of
      Permitted Disposition without any action required on behalf of the
      Collateral Agent. To the extent an El Paso Pledgor requests a lien release
      in connection with any such Permitted Disposition, the Collateral Agent
      shall as promptly as practicable (and in any event within ten (10)
      Business Days after such request) execute and deliver to such El Paso
      Pledgor, at such El Paso Pledgor's sole cost and expense, all such
      instruments (which instruments shall be reasonably satisfactory to the
      Collateral Agent) and take all such actions as reasonably requested by
      such El Paso Pledgor to effect the release of any liens or security
      interests held by the Collateral Agent on such Collateral.

                  (b) Any El Paso Pledgor may request from time to time that the
      Collateral Agent release Collateral to the extent the release is granted
      in connection with a Permitted Disposition described in clause (c) of the
      definition of Permitted Disposition. Such request shall be made pursuant
      to a Release Certificate. The Release Certificate shall be accompanied by
      execution counterparts of the instruments to be executed by the Collateral
      Agent (which instruments shall be reasonably satisfactory to the
      Collateral Agent) to effect such release. Promptly (and in any event
      within ten (10) Business Days) of the Collateral Agent's receipt of the
      Release Certificate, the Collateral Agent shall execute and deliver to
      such El Paso Pledgor, at such El Paso Pledgor's sole cost and expense, all
      such instruments (which instruments shall be reasonably satisfactory to
      the Collateral Agent) and take all such other actions as reasonably
      requested by such El Paso Pledgor to effect the release of any liens or
      security interests held by the Collateral Agent on such Collateral.

            4.2.3 If in connection with a release to be granted under the terms
of this Section 4.2, all of the Collateral granted or delivered in connection
with this Agreement and all other Security Documents by a particular El Paso
Pledgor has been surrendered or released, then the documents granting or
evidencing such surrender or release shall include an express acknowledgment
from the Collateral Agent that such El Paso Pledgor is fully released from all
the terms and conditions of this Agreement and any other Security Documents to
which it is a party (including any Guaranty), except to the extent that any
terms and conditions set forth therein expressly survive such surrender or
release.

            4.2.4 Upon the satisfaction in full of the Secured Obligations, the
Collateral Agent shall at the expense of the requesting El Paso Pledgor,
contemporaneously with such payment in full, (a) acknowledge in a written
instrument (in form and substance reasonably acceptable to the parties hereto)
the termination of this Agreement and the other Security

                                       17
<PAGE>

Documents, except to the extent that any terms and conditions set forth therein
expressly survive such termination, (b) execute and deliver to the El Paso
Pledgors instruments reflecting such release in full, and (c) and take all such
other actions as reasonably requested by the El Paso Pledgors to effect the
release of all liens or security interests held by the Collateral Agent on such
Collateral.

            4.2.5 Unless otherwise specified by the Collateral Agent, the El

additional Collateral has delivered to the Collateral Agent copies of the
documents listed in Sections 3.7(b)(i) through 3.7(b)(iii) in the four (4) month
period immediately prior to the pledging of such additional Collateral, then the
deliveries required pursuant to Sections 3.7(b)(i) through 3.7(b)(iii) shall not
be required and the certificate required by Section 3.7(b)(iv) shall certify
that that there has not been a material adverse change in the assets,
liabilities or financial condition of such El Paso Pledgor since the date on
which the items required by Section 3.7(b)(i) were last delivered), (b) a duly
executed Compliance Certificate dated as of the date of the Additional
Collateral Certificate which, if the additional Collateral includes Other
Collateral, gives effect to the coverage ratio required for such additional
Other Collateral by the Designated Representative, (c) in the case of Oil and
Gas Collateral, a supplemental report from an Independent Consultant confirming
the Reported Value of the Oil and Gas Collateral that is to be added, (d) in the

market value of the Other Collateral that is to be added, and (e) in the case of
the addition of Other Collateral, written confirmation addressed to the
Designated Representative from any rating agency rating any securities issued in
connection with a Monetization that any rating on such securities will not be

The additional Collateral shall be deemed to be held by the Collateral Agent
contemporaneously with the delivery by the El Paso Pledgor of the instruments
provided for in this Section 4.3.

      Section 4.4 Additional El Paso Pledgors. If after the Effective Date any
El Paso Settling Party or any direct or indirect wholly-owned Subsidiary of any
El Paso Settling Party not currently a party to this Agreement and that is a
Releasee under the Master Settlement Agreement provides Property as additional
Collateral, including Letters of Credit, under Paragraph 8.3(f) of the Master
Settlement Agreement, then such party shall automatically be deemed to be a
party to, and bound by the terms of, this Agreement from and after the date of
such grant without any further action. In connection therewith, the granting
party shall include an acknowledgement that such party shall be deemed to be an
El Paso Pledgor subject to the

                                       18

terms of this Agreement in the applicable Additional Collateral Certificate
and/or any Security Document to be executed by such party.

      Section 4.5 Additional Reports. With respect to the requirement in
Paragraph 8.3(f)(C) of the Master Settlement Agreement and Section 4.3 above, to
provide a supplemental report from an Independent Consultant confirming the
Reported Value of any Additional Oil and Gas Collateral, the El Paso Pledgor
delivering the report and associated Compliance Certificate and the Independent
Consultant shall have the right to provide such information based on the then
most recent Independent Consultant's report as updated by El Paso's internal
reviews if (a) such report was issued by the Independent Consultant one hundred
twenty (120) days or fewer days prior to the date on which the proposed
substitution or addition shall become effective, or (b) the Reported Value of
the Additional Oil and Gas Collateral, together with the Reported Value of all
Additional Oil and Gas Collateral provided pursuant hereto during the thirty
(30) days prior to the date on which the proposed substitution or addition shall
become effective, does not in the aggregate exceed five percent (5%) of the
Discounted Amount of the Deferred Payments calculated as of such effective date.

to be delivered by El Paso Corporation to the Collateral Agent under the terms
of the Master Settlement Agreement or this Agreement shall be in form and

      Section 5.1 Events of Default. Subject to the terms of Section 5.2 hereof,
the occurrence of any of the following events shall constitute an "Event of
Default" hereunder:

Default" under Paragraph 9.1 of the Master Settlement Agreement.

            5.1.2 Breach. (a) If any representation or warranty made or deemed
to be made by any El Paso Pledgor in this Agreement or in any other Security
Document, shall prove to have been incorrect in any material respect when made
or deemed to be made, (b) if the representation made by any El Paso Pledgor in
Section 2.1.3 of this Agreement or in any other Security Document relating to
whether such El Paso Pledgor is Solvent shall prove to have been incorrect when
made or deemed to be made, or (c) if any El Paso Pledgor shall in any material
respect fail to perform or observe any other term or covenant set forth in this
Agreement; or

            5.1.3 Invalidity of Security Documents. Any material provision of
this Agreement or any other Security Document shall for any reason cease to be
valid and binding on any El Paso Pledgor or any El Paso Pledgor shall so state
in writing; or

            5.1.4 Security Documents. (a) The Collateral Agent shall fail to
have a perfected lien or security interest in any Collateral, (b) any Security
Document shall at any time and for

                                       19
<PAGE>

any reason cease to create the lien on any Property purported to be subject to
such agreement or cease to be in full force and effect, or (c) the validity of
any Security Document shall be contested by any El Paso Pledgor.

      Section 5.2 Exceptions to Events of Default.

            5.2.1 Notice and Cure. With respect to any of the events provided
for in clauses 5.1.2(c), 5.1.4(a), and 5.1.4(b) above, such event shall not
constitute an Event of Default unless the same shall remain unremedied for
thirty (30) days after the earlier of written notice thereof by the Designated
Representative or Collateral Agent, and a Responsible Officer of El Paso
Corporation or the breaching El Paso Pledgor becoming aware of such failure;
provided, however, that if El Paso Corporation and/or the breaching party has
undertaken in good faith and with due diligence to cure such breach during the
30-day cure period and such breach is capable of being cured, then the breaching
party shall have an additional thirty (30) days to cure the breach.

            5.2.2 Minimum Collateral Coverage. If any El Paso Pledgor shall (a)
be in breach of any representation or warranty set forth in Sections 2.1.4, or
2.1.9 (a), (b), (c) or (e), (b) fail to perform or observe any term or covenant
set forth in any of Sections 3.3, 3.4, 3.5, or 3.8 of this Agreement, or (c) be
in default under Section 5.1.4(a) and/or 5.1.4(b) above, then in any such case
such failure or default shall not constitute an Event of Default if within
thirty (30) days after the earlier of written notice thereof by the Designated
Representative or Collateral Agent, and a Responsible Officer of El Paso
Corporation or the breaching El Paso Pledgor becoming aware of such failure or
default, El Paso Corporation delivers a Compliance Certificate to the Collateral
Agent certifying as of the date of such Compliance Certificate that
notwithstanding such breach, the Value of the Collateral is equal to or in
excess of the Minimum Collateral Coverage after taking into account the decline
in the Value of the Collateral caused by such breach, failure or default.

      Section 5.3 Remedies. An Event of Default hereunder constitutes an "Event
of Default" under Paragraph 9.1(c) of the Master Settlement Agreement. Upon the
occurrence of any Event of Default and during the continuance thereof, the
Designated Representative may, at its option, upon prior notice to El Paso
Corporation, exercise (or cause the Collateral Agent to exercise) any of the
rights and remedies provided for in the Master Settlement Agreement, this
Agreement and any of the other Security Documents. No remedy conferred upon the
Designated Representative or Collateral Agent hereunder or thereunder is
intended to be exclusive of any other remedy, and each remedy shall be
cumulative of all other remedies existing by contract, at law, in equity, by
statute or otherwise.

      Section 5.4 Rights Prior to an Event of Default. Notwithstanding anything
to the contrary contained herein or in any Deed of Trust or other Security
Document given by an El Paso Pledgor in connection with the Master Settlement
Agreement, each El Paso Pledgor that is a grantor under such a Deed of Trust or
other Security Document shall have, until the occurrence and continuance of an
Event of Default and written notice is provided to it by the "Beneficiary"
terminating its rights under this Section 5.4, the right to collect all
Hydrocarbons, payments received in lieu of Hydrocarbons, including as-extracted
Hydrocarbons, income, proceeds and other economic benefits attributable to the
Collateral subject thereto and the products obtained or

                                       20
<PAGE>

processed therefrom, execute division orders, transfer orders and other
instruments as may be required to direct all proceeds to such El Paso Pledgor
without the necessity of joinder by the "Beneficiary" under such Deed of Trust
in such division orders, transfer orders or other instruments, and use and enjoy
all Hydrocarbons, payments received in lieu of Hydrocarbons, income, proceeds
and other economic benefits attributable to the Collateral subject to such Deed
of Trust or other Security Documents and the products obtained or processed
therefrom free and clear of any liens granted in such Deed of Trust or other
Security Documents. Any amounts received by the Designated Representative, the
Collateral Agent, the Settlement Fund or any "Beneficiary" under any Deed of
Trust or any other Security Document to which the El Paso Pledgors are entitled
pursuant to the foregoing, shall be held in trust by the recipient and promptly
delivered to the applicable El Paso Pledgor. Notwithstanding anything in any
Deed of Trust or other Security Document to the contrary, neither the Designated
Representative, the Collateral Agent, the Settlement Fund nor any "Beneficiary"
shall exercise any of the rights set out in Section 3.1 (c), (d), (f) and (g) of
the Deed of Trust or any similar provisions within any other Security Document,
except after the occurrence and during the continuation of an Event of Default.

rights under this Section 5.4 have not been terminated or suspended.

                             ENVIRONMENTAL INDEMNITY

      Section 6.1 Environmental Indemnity. Each El Paso Pledgor shall indemnify,
defend and hold harmless the Designated Representative, the Collateral Agent,
the Settling Claimants, and each trustee under any Deed of Trust, and their
affiliates and each of their respective officers, directors, shareholders,
agents, and employees (each, an "Indemnified Party") from and against all
claims, demands, causes of action, suits, orders, damages, judgments, liens,
penalties, costs, and expenses, attorneys' fees and costs (whether incurred for
an Indemnified Party's primary defense or for enforcement of its indemnification
rights), including, without limitation, any claim for bodily or personal injury,
or death to any person, or loss or damage to Property, for any Environmental
Claim or requirement of any Environmental Law arising from any Security Document
as to which such El Paso Pledgor is a party or relating to such El Paso
Pledgor's ownership of the Collateral. WITHOUT LIMITATION, IT IS THE INTENTION
OF SUCH EL PASO PLEDGOR AND SUCH EL PASO PLEDGOR AGREES THAT THE FOREGOING
INDEMNITIES SHALL APPLY TO EACH INDEMNIFIED PARTY WITH RESPECT TO CLAIMS,
DEMANDS, CAUSES OF ACTION, SUITS, ORDERS, DAMAGES, JUDGMENTS, LIENS, PENALTIES
AND EXPENSES WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF STRICT
LIABILITY OR OUT OF THE NEGLIGENCE OF SUCH INDEMNIFIED PARTY, provided that such
indemnities shall not apply to any particular Indemnified Party (but shall apply
to the other Indemnified Parties) to the extent the subject of the
indemnification is caused by or arises out of the gross negligence or willful
misconduct of such particular Indemnified Party.

      Section 6.2 Notice of Claim. Promptly after receipt of notice of such
claim by any Indemnified Party, the Collateral Agent shall promptly give written
notification to the El Paso Pledgor owning the affected Collateral of any
Environmental Claim that could reasonably result

                                       21
<PAGE>

in an indemnity claim under Section 6.1. After receipt of such notification from
the Collateral Agent of any such Environmental Claim, such El Paso Pledgor shall
have the right upon notice to the Collateral Agent to defend, at its own
expenses and by its own counsel, any Environmental Claim and the Designated
Representative and Collateral Agent shall cooperate in such defense against such
Environmental Claim. Notwithstanding anything herein to the contrary, neither
the Designated Representative or the Collateral Agent may settle or compromise
any Environmental Claim over the objection of the El Paso Pledgor. In connection
with the defense of any Environmental Claim, the Designated Representative
Collateral Agent shall make available to the El Paso Pledgor any books, records,
or other documents within its control that are necessary or appropriate for such
defense.

                                   ARTICLE VII.
