SECTION 2.02. EXECUTION AND AUTHENTICATION.

         One Officer of the Partnership and one Officer of El Paso Finance shall
sign the Notes for the Partnership and El Paso Finance, respectively, by manual
or facsimile signature. The seal of the Partnership and El Paso Finance shall be
reproduced on the Notes and may be in facsimile form.

         If an Officer whose signature is on a Note no longer holds that office
at the time a Note is authenticated, the Note shall nevertheless be valid.

         A Note shall not be valid until authenticated by the manual signature
of the Trustee. The signature shall be conclusive evidence that the Note has
been authenticated under this Indenture.

         The Trustee shall, upon a written order of the Partnership and El Paso
Finance signed by one Officer of the Partnership and one Officer of El Paso
Finance, authenticate (i) $200,000,000 aggregate principal amount of Notes, with
the Guarantees endorsed thereon, for original issue on the Issue Date and (ii)
any amount of additional Notes specified by the Issuers, in each case, upon a
written order of the Partnership and El Paso Finance signed by one Officer of
the Partnership and one Officer of El Paso Finance. Such order shall specify (a)
the amount of the Notes of each series to be authenticated and the date of
original issue thereof, and (b) whether the Notes are Series A Notes or Exchange
Notes. The aggregate principal amount of Notes of any series outstanding at any
time may not exceed the aggregate principal amount of Notes of such series
authorized for issuance by the Issuers pursuant to one or more written orders of
the Issuers, except as provided in Section 2.07 hereof. Subject to the
foregoing, the aggregate principal amount of Notes of any series that may be
issued under this Indenture shall not be limited.

SECTION 2.03. REGISTRAR AND PAYING AGENT.

transfer or for exchange ("Registrar") and an office or agency in the State of
New York where Notes may be presented for payment ("Paying Agent"). The
Registrar shall keep a register of the Notes and of their transfer and exchange.
The Issuers may appoint one or more co-registrars and one or more additional
paying agents. The term "Registrar" includes any co-registrar and the term
"Paying Agent" includes any additional paying agent. The Issuers may change any
Paying Agent or Registrar without notice to any Holder. The Issuers shall notify
the Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Issuers fail to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The


                                       31
<PAGE>
Partnership, El Paso Finance or any of the Subsidiary Guarantors may act as
Paying Agent or Registrar.

act as Depositary with respect to the Global Notes.

         The Issuers initially appoint the Trustee to act as the Registrar and
Paying Agent and to act as Note Custodian with respect to the Global Notes.

SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST.

         The Issuers shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium, if any, or interest or Liquidated Damages, if any, on the
Notes, and will notify the Trustee of any default by the Partnership, El Paso
Finance or the Subsidiary Guarantors in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee. The Issuers at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than an Issuer or a Subsidiary Guarantor) shall have no
further liability for the money. If an Issuer or a Subsidiary Guarantor acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy
or reorganization proceedings relating to the Partnership or El Paso Finance,
the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.05. HOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee
is not the Registrar, the Issuers shall furnish to the Trustee at least seven
Business Days before each Interest Payment Date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Notes and the Issuers shall otherwise comply with TIA Section 312(a).

transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes may be exchanged by
the Issuers for Certificated Notes if (i) the Issuers deliver to the Trustee
notice from the Depositary that it is unwilling or unable to continue to act as
Depositary or that it is no longer a clearing agency registered under the
Exchange Act and, in either case, a successor Depositary is not appointed by the
Issuers within 90 days after the date of such notice from the Depositary, (ii)
the Issuers in their sole discretion determine that the Global Notes (in whole
but not in part) should be exchanged for Certificated Notes and deliver a
written notice to such effect to the Trustee; provided that in no event shall
the Regulation S Global Note


                                       32
<PAGE>
be exchanged by the Issuers for Certificated Notes prior to (x) the expiration
of the Distribution Compliance Period and (y) the receipt by the Registrar of
any certificates required pursuant to Rule 903 under the Securities Act, or
(iii) if a Default or an Event of Default occurs and is continuing. Whenever a
Global Note is exchanged as a whole for one or more Certificated Notes, it shall
be surrendered by the Holder thereof to the Trustee for cancellation. Whenever a
Global Note is exchanged in part for one or more Certificated Notes, it shall be
surrendered by the Holder thereof to the Trustee and the Trustee shall make the
appropriate notations to the Schedule of Exchanges of Interests in the Global
Notes attached thereto pursuant to Section 2.01 hereof. All Certificated Notes
issued in exchange for a Global Note or any portion thereof shall be registered
in such names, and delivered, as the Depositary shall instruct the Trustee.
Global Notes also may be exchanged or replaced, in whole or in part, as provided
in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to
Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form
of, and shall be, a Global Note. A Global Note may not be exchanged for another
Note other than as provided in this Section 2.06(a), however, beneficial
interests in a Global Note may be transferred and exchanged as provided in
Section 2.06(b), (c) or (f) hereof.

         (b) Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes shall be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes shall be subject to restrictions on transfer comparable to those
set forth herein to the extent required by the Securities Act. Transfers of
beneficial interests in the Global Notes also shall require compliance with
either subparagraph (i) or (ii) below, as applicable, as well as one or more of
the other following subparagraphs as applicable:

                  (i) Transfer of Beneficial Interests in the Same Global Note.
         Beneficial interests in any Restricted Global Note may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in the same Restricted Global Note in accordance with the
         transfer restrictions set forth in the Private Placement Legend;
         provided, however, that prior to the expiration of the Distribution
         Compliance Period transfers of beneficial interests in the Regulation S
         Global Note may not be made to a U.S. Person or for the account or
         benefit of a U.S. Person (other than an Initial Purchaser). Beneficial
         interests in any Unrestricted Global Note may be transferred only to
         Persons who take delivery thereof in the form of a beneficial interest
         in an Unrestricted Global Note. No written orders or instructions shall
         be required to be delivered to the Registrar to effect the transfers
         described in this Section 2.06(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial Interests
         in Global Notes. In connection with all transfers and exchanges of
         beneficial interests (other than a transfer of a beneficial interest in
         a Global Note to a Person who takes delivery thereof in the form of a
         beneficial interest in the same Global Note), the transferor of such
         beneficial interest must deliver to the Registrar either (A) (i) a
         written order from a Participant or an Indirect Participant given to
         the Depositary in accordance with the Applicable Procedures directing
         the Depositary to credit or cause to be credited a beneficial interest
         in another Global Note in an


                                       33
<PAGE>
         amount equal to the beneficial interest to be transferred or exchanged
         and (ii) instructions given in accordance with the Applicable
         Procedures containing information regarding the Participant account to
         be credited with such increase or (B) (i) a written order from a
         Participant or an Indirect Participant given to the Depositary in
         accordance with the Applicable Procedures directing the Depositary to
         cause to be issued a Certificated Note in an amount equal to the
         beneficial interest to be transferred or exchanged and (ii)
         instructions given by the Depositary to the Registrar containing
         information regarding the Person in whose name such Certificated Note
         shall be registered to effect the transfer or exchange referred to in
         (i) above; provided that in no event shall Certificated Notes be issued
         upon the transfer or exchange of beneficial interests in the Regulation
         S Global Note prior to (x) the expiration of the Distribution
         Compliance Period and (y) the receipt by the Registrar of any
         certificates required pursuant to Rule 903 under the Securities Act.
         Upon an Exchange Offer by the Issuers in accordance with Section
         2.06(f) hereof, the requirements of this Section 2.06(b)(ii) shall be
         deemed to have been satisfied upon receipt by the Registrar of the
         instructions contained in the Letter of Transmittal delivered by the
         Holder of such beneficial interests in the Restricted Global Notes.
         Upon satisfaction of all of the requirements for transfer or exchange
         of beneficial interests in Global Notes contained in this Indenture,
         the Notes and otherwise applicable under the Securities Act, the
         Trustee shall adjust the principal amount of the relevant Global
         Note(s) pursuant to Section 2.06(h) hereof.

                  (iii) Transfer of Beneficial Interests to Another Restricted
         Global Note. A beneficial interest in any Restricted Global Note may be
         transferred to a Person who takes delivery thereof in the form of a
         beneficial interest in another Restricted Global Note if the transfer
         complies with the requirements of clause (ii) above and the Registrar
         receives the following:

                           (A) if the transferee will take delivery in the form
                  of a beneficial interest in the 144A Global Note, then the
                  transferor must deliver a certificate in the form of Exhibit B
                  hereto, including the certifications in item (1) thereof;

                           (B) if the transferee will take delivery in the form

                  thereof; and

                           (C) if the transferee will take delivery in the form
                  of a beneficial interest in the IAI Global Note, then the
                  transferor must deliver (x) a certificate in the form of
                  Exhibit B hereto, including the certifications and
                  certificates and Opinion of Counsel required by item (3)(c)
                  thereof, if applicable.

                           reasonably acceptable to the Issuers to the effect
                           that such exchange or transfer is in compliance with
                           the Securities Act, that the restrictions on transfer
                           contained herein and in the Private Placement Legend
                           are not required in order to maintain compliance with
                           the Securities Act, and such Certificated Notes are
                           being exchanged or transferred in compliance with any
                           applicable blue sky securities laws of any State of

         Note or transfer such Certificated Notes to a Person who takes delivery
         thereof in the form of a beneficial interest in an Unrestricted Global

                  contrary.

                           (vii) The Trustee shall authenticate Global Notes and
                  Certificated Notes (in each case, accompanied by a notation of
                  the Guarantees duly endorsed by the Subsidiary Guarantors) in
                  accordance with the provisions of Section 2.02 hereof.

                           (viii) All certifications, certificates and opinions
                  of counsel required to be submitted to the Registrar pursuant
                  to this Section 2.06 to effect a transfer or exchange may be
                  submitted by facsimile.

                           (ix) Each Holder of a Note agrees to indemnify the
                  Issuers and the Trustee against any liability that may result
                  from the transfer, exchange or assignment of such Holder's
                  Note in violation of any provision of this Indenture and/or
                  applicable United States federal or state securities law.

         (j) Each beneficial owner of an interest in a Note agrees to indemnify

and other documentation or evidence as are expressly required by, and to do so
if and when expressly required by the terms of, this Indenture, and to examine
the same to determine substantial compliance as to form with the express
requirements hereof.

SECTION 2.07. REPLACEMENT NOTES.

         If any mutilated Note is surrendered to the Trustee or either of the
Issuers and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Issuers shall issue and the Trustee,
upon the written order of the Issuers signed by one Officer of the Partnership
and one Officer of El Paso Finance, shall authenticate a replacement Note


                                       46
<PAGE>
(accompanied by a notation of the Guarantees duly endorsed by the Subsidiary
Guarantors) if the Trustee's requirements are met. An indemnity bond must be
supplied by the Holder that is sufficient in the judgment of the Trustee and the
Issuers to protect the Issuers, the Subsidiary Guarantors, the Trustee, any
Agent and any authenticating agent from any loss that any of them may suffer if
a Note is replaced. The Issuers may charge for their expenses in replacing a
Note.

         Every replacement Note is an additional obligation of the Issuers and
the Subsidiary Guarantors and shall be entitled to all of the benefits of this
Indenture equally and proportionately with all other Notes duly issued
hereunder. The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement of mutilated, destroyed, lost or stolen Notes.

SECTION 2.08. OUTSTANDING NOTES.

         The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because an Issuer or an Affiliate of an Issuer
holds the Note.

         If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

         If the principal amount of any Note is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest and Liquidated Damages, if
applicable, on it cease to accrue.

         If the Paying Agent (other than an Issuer or a Subsidiary or an
Affiliate of an Issuer) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest (and Liquidated Damages, if any).

SECTION 2.09. TREASURY NOTES.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by an
Issuer, by any Subsidiary Guarantor or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Partnership or any Subsidiary Guarantor, shall be considered as though not
outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Notes that a Responsible Officer of the Trustee actually knows are so owned
shall be so disregarded.

SECTION 2.010. TEMPORARY NOTES.

         Until Certificated Notes are ready for delivery, the Issuers may
prepare and the Trustee shall authenticate temporary Notes (accompanied by a
notation of the Guarantees duly

                                       47
<PAGE>
endorsed by the Subsidiary Guarantors) upon a written order of the Issuers
signed by one Officer of the Partnership and one Officer of El Paso Finance.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Issuers consider appropriate for temporary Notes and as
shall be reasonably acceptable to the Trustee. Without unreasonable delay, the
Issuers shall prepare and the Trustee shall authenticate definitive Notes
(accompanied by a notation of the Guarantees duly endorsed by the Subsidiary
Guarantors) in exchange for temporary Notes.

         Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

SECTION 2.11. CANCELLATION.

         Either of the Issuers at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall treat such
canceled Notes in accordance with its documents retention policies. The Issuers
may not issue new Notes to replace Notes that it has paid or that have been
delivered to the Trustee for cancellation.

SECTION 2.12. DEFAULTED INTEREST.

         If any of the Partnership, El Paso Finance or any Subsidiary Guarantor
defaults in a payment of interest on the Notes, it or they (to the extent of
their obligations under the Guarantees) shall pay the defaulted interest in any
lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date, in
each case at the rate provided in the Notes and in Section 4.01 hereof. The
Issuers shall notify the Trustee in writing of the amount of defaulted interest
proposed to be paid on each Note and the date of the proposed payment. The
Issuers shall fix or cause to be fixed each such special record date and payment
date, provided that no such special record date shall be less than 10 days prior
to the related payment date for such defaulted interest. At least 15 days before
the special record date, the Issuers (or, upon the written request of the
Issuers, the Trustee in the name and at the expense of the Issuers) shall mail
or cause to be mailed to Holders a notice that states the special record date,
the related payment date and the amount of such interest to be paid.

SECTION 2.13. CUSIP NUMBERS.

         The Issuers in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if they do so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Issuers will promptly notify the Trustee of any
change in the "CUSIP" numbers.

         If an Issuer elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 35
days (unless a shorter period is acceptable to the Trustee) but not more than 60
days before a redemption date, an Officers' Certificate setting forth (i) the
clause of this Indenture pursuant to which the redemption shall occur, (ii) the
redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the
redemption price.

SECTION 3.02. SELECTION OF NOTES TO BE REDEEMED.

         If less than all of the Notes are to be redeemed at any time, the
Trustee will select Notes for redemption as follows:

         securities exchange, in compliance with the requirements of the
         principal national securities exchange on which the Notes are so
         listed; or

                  (b) if the Notes are not so listed or there are no such
         requirements, on a pro rata basis, by lot or by such method as the
         Trustee shall deem fair and appropriate.

         No Notes of $1,000 or less shall be redeemed in part. Notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each Holder of Notes to be redeemed at its
registered address. Notices of redemption may not be conditional.

         If any Note is to be redeemed in part only, the notice of redemption
that relates to that Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion of the original Note will be issued in the name of the Holder thereof
upon cancellation of the original Note. Notes called for redemption become due
on the date fixed for redemption. On and after the redemption date, interest and
Liquidated Damages, if applicable, cease to accrue on Notes or portions of them
called for redemption unless the Issuers default in making such redemption
payment.

SECTION 3.03. NOTICE OF REDEMPTION.

         At least 30 days but not more than 60 days before a redemption date,
the Issuers shall mail or cause to be mailed, by first class mail, a notice of

<PAGE>
                  (b) the redemption price;

                  (c) if any Note is being redeemed in part, the portion of the
         principal amount of such Note to be redeemed and that, after the
         redemption date upon surrender of such Note, a new Note or Notes in
         principal amount equal to the unredeemed portion shall be issued upon
         cancellation of the original Note;

                  (d) the name and address of the Paying Agent;

                  (e) that Notes called for redemption (other than a Global
         Note) must be surrendered to the Paying Agent to collect the redemption
         price;

                  (f) that, unless the Issuers default in making such redemption
         payment, interest and Liquidated Damages, if applicable, on Notes
         called for redemption cease to accrue on and after the redemption date;

                  (g) the paragraph of the Notes and/or Section of this
         Indenture pursuant to which the Notes called for redemption are being
         redeemed; and

                  (h) that no representation is made as to the correctness or
         accuracy of the CUSIP number, if any, listed in such notice or printed
         on the Notes.

         At the Issuers' request, the Trustee shall give the notice of
redemption in the Issuers' names and at their expense; provided, however, that
the Issuers shall have delivered to the Trustee, at least 45 days prior to the
redemption date (unless a shorter period is otherwise acceptable to the
Trustee), an Officers' Certificate requesting that the Trustee give such notice
and setting forth the information to be stated in such notice as provided in the
preceding paragraph.

SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION.

         Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.05. DEPOSIT OF REDEMPTION PRICE.

         Not later than 11:00 a.m., New York City time, on the redemption date,

the Paying Agent shall promptly return to the Issuers any money deposited with
the Trustee or the Paying Agent by the Issuers in excess of the amounts
necessary to pay the redemption price of, and accrued interest and Liquidated
Damages, if applicable, on, all Notes to be redeemed.

applicable, shall cease to accrue on the Notes or the portions of Notes called
for redemption. If a Note is redeemed on or after an interest


                                       50
<PAGE>

accrued and unpaid interest (and Liquidated Damages, if any) shall be paid to
the Person in whose name such Note was registered at the close of business on
such record date. If any Note called for redemption shall not be so paid upon
surrender for redemption because of the failure of the Issuers to comply with
the preceding paragraph, interest (and Liquidated Damages, if any) shall be paid
on the unpaid principal, from the redemption date until such principal is paid,
and to the extent lawful on any interest not paid on such unpaid principal, in
each case at the rate provided in the Notes and in Section 4.01 hereof.

SECTION 3.06. NOTES REDEEMED IN PART.

         Upon surrender of a Note that is redeemed in part, the Issuers shall
issue and, upon the Issuers' written request, the Trustee shall authenticate for
the Holder at the expense of the Issuers a new Note (accompanied by a notation
of the Guarantees duly endorsed by the Subsidiary Guarantors) equal in principal
amount to the unredeemed portion of the Note surrendered.

SECTION 3.08. MANDATORY REDEMPTION.

         Except for any repurchase offers required to be made pursuant to
Sections 4.06 and 4.07 hereof, the Issuers shall not be required to make
mandatory redemption payments with respect to the Notes.

SECTION 3.09. OFFER TO PURCHASE BY APPLICATION OF NET PROCEEDS.

         In the event that, pursuant to Section 4.07 hereof, the Issuers shall
be required to commence a pro rata offer (an "Asset Sale Offer") to all Holders
and all holders of other Indebtedness that is pari passu with the Notes
containing provisions similar to those set forth in this Indenture with respect
to offers to purchase or redeem with the Net Proceeds of sales of assets to
purchase Notes and such other pair passu Indebtedness, it shall follow the
procedures specified below.

         The Asset Sale Offer shall remain open for a period of at least 30 days
following its commencement but no longer than 60 days, except to the extent that
a longer period is required by applicable law (the "Offer Period"). Promptly
after the termination of the Offer Period (the "Purchase Date"), the Issuers
shall purchase the principal amount of Notes required to be purchased pursuant
to Section 4.07 hereof (the "Offer Amount") or, if less than the Offer Amount
has been tendered, all Notes tendered and not withdrawn in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

         If the Purchase Date is on or after an interest record date and on or
before the related Interest Payment Date, accrued and unpaid interest, if any,
and Liquidated Damages (to the extent involving interest that is due and payable
on such Interest Payment Date), if any, shall be paid to the Person in whose
name a Note is registered at the close of business on such record date, and no
additional interest (or Liquidated Damages, if any) shall be payable to Holders
who validly tender Notes pursuant to the Asset Sale Offer.

         Upon the commencement of an Asset Sale Offer, the Issuers shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

         (a) that the Asset Sale Offer is being made pursuant to this Section
3.09 and Section 4.07 hereof and the length of time the Asset Sale Offer shall
remain open;

         (b) the Offer Amount, the purchase price and the Purchase Date;

         (c) that any Note not validly tendered or accepted for payment shall
continue to accrue interest and Liquidated Damages, if applicable;

         (d) that, unless the Issuers default in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
interest and Liquidated Damages, if applicable, after the Purchase Date;

Asset Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or

the Issuers, or a Paying Agent at the address specified in the notice at least
three days before the Purchase Date;

         (f) that Holders shall be entitled to withdraw their election if the
Issuers, the Depositary or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased;

         (g) that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the Offer Amount, the Issuers shall select the Notes to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Issuers so that only Notes in denominations of $1,000, or
integral multiples thereof, shall be purchased); and

         (h) that Holders whose Notes were purchased only in part shall be
issued new Notes (accompanied by a notation of the Guarantees duly endorsed by
the Subsidiary Guarantors) equal in principal amount to the unpurchased portion
of the Notes surrendered (or transferred by book-entry transfer).

         On or before the Purchase Date, the Issuers shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof validly tendered and not properly
withdrawn pursuant to the Asset Sale Offer, or if less than the Offer Amount has
been validly tendered and not properly withdrawn, all Notes so tendered and not
withdrawn, and shall deliver to the Trustee an Officers' Certificate stating
that such Notes or portions thereof were accepted for payment by the Issuers in
accordance with the terms of this Section 3.09. Upon surrender and cancellation
of a Certificated Note that is purchased in part, the Issuers shall promptly
issue and the Trustee shall authenticate and deliver to the surrendering Holder
of such Certificated Note a new Certificated Note equal in principal amount to
the unpurchased portion of such surrendered Certificated Note; provided that
each such new Certificated Note shall be in a principal amount of $1,000 or an
integral multiple thereof. Upon surrender of a Global Note that is purchased in
part pursuant to an Asset Sale Offer, the Paying Agent shall forward such Global
Note to the Trustee who shall make an endorsement thereon to reduce the
principal amount of such Global Note to an amount equal to the unpurchased
portion of such Global Note, as provided in Section 2.06(h) hereof. The Issuers,
the Depositary or the Paying Agent, as the case may be, shall promptly mail or
deliver to each tendering Holder an amount equal to the purchase price of the
Notes tendered by such Holder and accepted by the Issuers for purchase, and the
Issuers shall promptly issue a new Note (in each case, accompanied by a notation
of the Guarantees duly endorsed by the Subsidiary Guarantors), and the Trustee,
upon written request from the Issuers shall authenticate and mail or deliver
such new Note to such Holder, in a principal amount equal to any unpurchased
portion of the Note surrendered. Any Note not so accepted shall be promptly
mailed or delivered by the Issuers to the Holder thereof. The Issuers shall
publicly announce the results of the Asset Sale Offer on the Purchase Date.

lawful.

SECTION 4.02. MAINTENANCE OF OFFICE OR AGENCY.

         The Issuers shall maintain in the Borough of Manhattan, The City of New
York, an office or agency (which may be an office of the Trustee or an Affiliate
of the Trustee, Registrar or co-registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Issuers or the Subsidiary Guarantors in respect of the Notes and this
Indenture may be served. The Issuers shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or

Restricted Subsidiaries of the Partnership during the preceding fiscal year has
been made under the supervision of the signing Officers with a view to
determining whether the Issuers and the Subsidiary Guarantors have kept,
observed, performed and fulfilled their respective obligations under this
Indenture and the Guarantees, respectively, and further stating, as to each such
Officer signing such certificate, that to the best of his or her knowledge each
of such Issuers and such Subsidiary Guarantors, as the case may be, has kept,
observed, performed and fulfilled each and every covenant contained in this
Indenture and is not in default in the performance or observance of any of the
terms, provisions and conditions of this Indenture (or, if a Default or Event of
Default shall have occurred, describing all such Defaults or Events of Default
of which he or she may have knowledge and what action such Issuer or such
Subsidiary Guarantor, as the case may be, is taking or proposes to take with
respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest, if any, on the Notes is prohibited or if such event
has occurred, a description of the event and what action such Issuer or such
Subsidiary Guarantor, as the case may be, is taking or proposes to take with
respect thereto.

         (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.19(a) shall be accompanied by a
written statement of the Issuers' independent public accountants (who shall be a
firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Issuers have violated
any provisions of Article 4 or Article 5 hereof (except that such written
statement need not address the Issuers' and Subsidiary Guarantors' compliance
with Sections 4.02, 4.05, 4.06 or 4.13 hereof) or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

         (c) Each of the Issuers shall, so long as any of the Notes are
outstanding, deliver to the Trustee, forthwith upon any Officer of the
Partnership, the General Partner or El Paso Finance becoming aware of any
Default or Event of Default, an Officers' Certificate specifying such Default or
Event of Default and what action the Issuers are taking or propose to take with
respect thereto.

SECTION 4.04. TAXES.

         The Issuers shall pay, and shall cause each of its Restricted
Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and
governmental levies except such as are contested in good faith and by
appropriate proceedings or where the failure to effect such payment is not
adverse in any material respect to the Holders of the Notes.

SECTION 4.05. STAY, EXTENSION AND USURY LAWS.

         Each of the Issuers and the Subsidiary Guarantors covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay, extension or usury law wherever enacted, now or at any time hereafter
in force, that may affect the covenants or the performance of this Indenture;
and each of the Issuers and the Subsidiary Guarantors (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

SECTION 4.06. CHANGE OF CONTROL.

         (a) If a Change of Control occurs, each Holder of Notes shall have the
right to require the Issuers to repurchase all or any part (equal to $1,000 or
an integral multiple thereof) of that Holder's Notes pursuant to the offer
described below (the "Change of Control Offer"). In the Change of Control Offer,
the Issuers shall offer a "Change of Control Payment" in cash equal to 101% of
the aggregate principal amount of Notes repurchased plus accrued and unpaid
interest thereon, if any, and Liquidated Damages, if any, to the date of
purchase (the "Change of Control Payment"). Within 30 days following any Change
of Control, the Issuers shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Notes on the Change of Control Payment Date specified in such
notice, pursuant to the procedures required by this Indenture and described in
such notice. If the Change of Control Payment Date is on or after a record date
and on or before the related Interest Payment Date, any accrued and unpaid
interest and Liquidated Damages (to the extent involving interest that is due
and payable on such Interest Payment Date), if any, shall be paid to the Person
in whose name a Note is registered at the close of business on such record date,
and no additional interest (or Liquidated Damages, if any) (to the extent
involving interest that is due and payable on such Interest Payment Date) shall
be payable to Holders who validly tender Notes pursuant to the Change of Control
Offer. The Issuers shall comply with the requirements of Rule 14e-l under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

         (b) Within 30 days following any Change of Control, the Issuers shall
mail by first class mail, a notice to each Holder, with a copy of such notice to
the Trustee. The notice, which shall govern the terms of the Change of Control
Offer, shall state, among other things:

                  (i) that a Change of Control has occurred and a Change of
         Control Offer is being made as provided for herein, and that, although
         Holders are not required to tender their Notes, all Notes that are
         validly tendered shall be accepted for payment;


                                       56
<PAGE>
                  (ii) the Change of Control Payment and the Change of Control
         Payment Date, which will be no earlier than 30 days and no later than
         60 days after the date such notice is mailed;

                  (iii) that any Note accepted for payment pursuant to the
         Change of Control Offer (and duly paid for on the Change of Control
         Payment Date) shall cease to accrue interest and Liquidated Damages, if
         applicable, after the Change of Control Payment Date;

                  (iv) that any Notes (or portions thereof) not validly tendered
         shall continue to accrue interest and Liquidated Damages, if
         applicable;

                  (v) that any Holder electing to have a Note purchased pursuant
         to any Change of Control Offer shall be required to surrender the Note,
         with the form entitled "Option of Holder to Elect Purchase" on the
         reverse of the Note completed, or transfer by book-entry transfer, to
         the Issuers, a depositary, if appointed by the Issuers, or a Paying
         Agent at the address specified in the notice at least one (1) Business
         Day before the Change of Control Payment Date;

                  (vi) that Holders shall be entitled to withdraw their election
         if the Issuers, the Depositary or the Paying Agent, as the case may be,
         receives, not later than the expiration of the Change of Control Offer,
         a telegram, facsimile transmission or letter setting forth the name of
         the Holder, the principal amount of the Note the Holder delivered for
         purchase and a statement that such Holder is withdrawing his election
         to have such Note purchased; and

                  (vii) the instructions and any other information necessary to
         enable Holders to tender their Notes (or portions thereof) and have
         such Notes (or portions thereof) purchased pursuant to the Change of
         Control Offer.

         (c) Subject to Section 4.06(f), on the Change of Control Payment Date,
the Issuers shall, to the extent lawful:

                  (i) accept for payment all Notes or portions thereof properly
         tendered and not withdrawn pursuant to the Change of Control Offer;

                  (ii) deposit by 11:00 a.m., New York Time with the Paying
         Agent an amount equal to the Change of Control Payment in respect of
         all Notes or portions thereof so tendered; and


                                       57
<PAGE>
                  (iii) deliver or cause to be delivered to the Trustee the
         Notes so accepted together with an Officers' Certificate stating the
         aggregate principal amount of Notes or portions thereof being purchased
         by the Issuers.

         (d) The Paying Agent shall promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that each such new Note shall be in a
principal amount of $1,000 or an integral multiple thereof. The Issuers shall
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

         (e) Upon surrender and cancellation of a Certificated Note that is
purchased in part pursuant to the Change of Control Offer, the Issuers shall
promptly issue and the Trustee shall authenticate and mail (or cause to be
transferred by book entry) to the surrendering Holder of such Certificated Note,
a new Certificated Note equal in principal amount to the unpurchased portion of
such surrendered Certificated Note; provided that each such new Certificated
Note shall be in principal amount of $1,000 or an integral multiple thereof.

         (f) Prior to complying with any of the provisions of this Section 4.06,
but in any event within 90 days following a Change of Control, the Issuers shall
either repay all outstanding Senior Debt or obtain the requisite consents, if
any, under all agreements governing outstanding Senior Debt to permit the
repurchase of Notes required by this covenant.

         (g) The provisions described in this Section 4.06 require the Issuers
to make a Change of Control Offer following a Change of Control shall be
applicable regardless of whether or not any other provisions of this Indenture
are applicable.

         (h) Notwithstanding the other provisions of this Section 4.06, the
Issuers shall not be required to make a Change of Control Offer upon a Change of
Control, and a Holder will not have the right to require that the Issuers
repurchase any Notes pursuant to a Change of Control Offer, if a third party
makes the Change of Control Offer in the manner, at the times and otherwise in
compliance with the requirements set forth in this Indenture applicable to a
Change of Control Offer made by the Issuers and purchases all Notes validly
tendered and not withdrawn under such Change of Control Offer.

SECTION 4.07. ASSET SALES.

         (a) The Issuers shall not, and shall not permit any Restricted
Subsidiary of the Partnership to, consummate an Asset Sale unless:

                  (i) such Issuer (or the Restricted Subsidiary, as the case may
         be) receives consideration at the time of such Asset Sale at least
         equal to the fair market value of the assets or Equity Interests issued
         or sold or otherwise disposed of;

                  (ii) such fair market value is determined by (a) an executive
         officer of the Partnership if the value is less than $10.0 million, as
         evidenced by an Officers'


                                       58
<PAGE>
         Certificate delivered to the Trustee or (b) the Board of Directors of
         the General Partner if the value is $10.0 million or more, as evidenced
         by a resolution of such Board of Directors of the General Partner; and

                  (iii) at least 75% of the Net Proceeds received by such Issuer
         or such Restricted Subsidiary is in the form of cash or Cash
         Equivalents.

         For purposes of this clause (iii), each of the following shall be
         deemed to be cash:

                  (A) any liabilities (as shown on such Issuer's or such
         Restricted Subsidiary's most recent balance sheet), of the Issuers or
         any Restricted Subsidiary (other than contingent liabilities and
         liabilities that are by their terms subordinated to the Notes or any
         Guarantee) that are assumed by the transferee of any such assets
         pursuant to a customary novation agreement that releases such Issuer or
         such Restricted Subsidiary from further liability; and

                  (B) any securities, notes or other obligations received by
         such Issuer or any such Restricted Subsidiary from such transferee that
         are within 90 days after the Asset Sales (subject to ordinary
         settlement periods) converted by such Issuer or such Restricted
         Subsidiary into cash (to the extent of the cash received in that
         conversion).

         (b) Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Partnership or a Restricted Subsidiary may apply (or enter into a
definitive agreement for such application, provided that such capital
expenditure or purchase is closed within 90 days after the end of such 360-day
period) such Net Proceeds at its option: (i) to repay Senior Debt of the
Partnership and/or its Restricted Subsidiaries (or to make an offer to
repurchase or redeem any such Senior Debt, provided that such repurchase or
redemption closes within 45 days after the end of such 360-day period) with a
permanent reduction in availability for any revolving credit Indebtedness;

                  (i) to make a capital expenditure in a Permitted Business;

                  (ii) to acquire other long-term tangible assets that are used
         or useful in a Permitted Business; or

                  (iii) to invest in any other Permitted Business Investment or
         any other Permitted Investments other than Investments in Cash
         Equivalents, Interest Swaps or Currency Agreements.

Pending the final application of any such Net Proceeds, the Partnership or a
Restricted Subsidiary may temporarily reduce revolving credit borrowings or
otherwise invest such Net Proceeds in any manner that is not prohibited by this
Indenture.

         (c) Any Net Proceeds from Asset Sales that are not applied or invested
as provided in Section 4.07(b) above will constitute "Excess Proceeds". When the
aggregate amount of Excess Proceeds exceeds $10 million, the Issuers will make a
pro rata offer (an "Asset Sale Offer") to all Holders of Notes and all holders
of other Indebtedness that is pari passu with


                                       59
<PAGE>
the Notes containing provisions similar to those set forth in this Indenture
with respect to offers to purchase or redeem with the proceeds of sales of
assets to purchase the maximum principal amount of Notes and such other pari
passu Indebtedness that may be purchased out of the Excess Proceeds. The offer
price in any Asset Sale Offer will be equal to 100% of principal amount plus
accrued and unpaid interest (including any Liquidated Damages in the case of the
Notes), if any, and premium, if any, to the date of purchase, and will be
payable in cash. If any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Partnership may use such Excess Proceeds for any purpose not
otherwise prohibited by this Indenture, including, without limitation, the
repurchase or redemption of Indebtedness of the Issuers or any Subsidiary
Guarantor that is subordinated to the Notes or, in the case of any Subsidiary
Guarantor, the Guarantee of such Subsidiary Guarantor. If the aggregate
principal amount of Notes tendered into such Asset Sale Offer exceeds the amount
of Excess Proceeds allocated for repurchases of Notes pursuant to the Asset Sale
Offer for Notes, the Trustee shall select the Notes to be purchased on a pro
rata basis. Upon completion of each Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero.

         (d) Notwithstanding the definition of the term "Asset Sale" in Section
1.01 hereof, the following transactions shall not constitute an Asset Sale for
purposes of this Indenture:

                  (i) any transaction whereby assets or properties (including
         (a) ownership interests in any Subsidiary or Joint Venture and (b) in
         the case of an exchange or contribution for tangible assets, up to 25%
         in the form of cash, Cash Equivalents, accounts receivable or other
         current assets), owned by the Partnership or a Restricted Subsidiary of
         the Partnership are exchanged or contributed for the Equity Interests
         of a Joint Venture or Unrestricted Subsidiary in a transaction that
         satisfies the requirements of a Permitted Business Investment or for
         other assets (not more than 25% of which consists of cash, Cash
         Equivalents, accounts receivables or other current assets) or
         properties (including interests in any Subsidiary or Joint Venture) so
         long as (i) the fair market value of the assets or properties (if other
         than a Permitted Business Investment) received are substantially
         equivalent to the fair market value of the assets or properties given
         up, and (ii) any cash received in such exchange or contribution by the
         Partnership or any Restricted Subsidiary of the Partnership is applied
         in accordance with the foregoing provisions of this Section 4.07;

                  (ii) any sale, transfer or other disposition of cash or Cash
         Equivalents;

                  (iii) any sale, transfer or other disposition of Restricted
         Investments; and

                  (iv) any sale, transfer or other disposition of interests in
         oil and gas leaseholds (including, without limitation, by abandonment,
         farm-ins, farm-outs, leases, swaps and subleases), hydrocarbons and
         other mineral products in the ordinary course of business of the oil
         and gas operations conducted by the Partnership or any Restricted
         Subsidiary of the Partnership, which sale, transfer or other
         disposition is made by the Partnership or any such Restricted
         Subsidiary.

SECTION 4.08.     RESTRICTED PAYMENTS.

         (a) The Issuers shall not, and shall not permit any of their Restricted
Subsidiaries to, directly or indirectly:

                  (i) declare or pay any dividend or make any other payment or
         distribution on account of the Equity Interests of the Partnership or
         any of its Restricted Subsidiaries (including, without limitation, any
         payment in connection with any merger or consolidation involving the
         Partnership or any of its Restricted Subsidiaries) or to the direct or
         indirect holders of the Equity Interests of the Partnership or of any
         of its Restricted Subsidiaries in their capacity as such (other than
         dividends or distributions payable in Equity Interests of the
         Partnership (other than Disqualified Equity) and other than
         distributions or dividends payable to the Partnership or a Restricted
         Subsidiary of the Partnership).

                  (ii) except to the extent permitted in clause (iv) below,
         purchase, redeem or otherwise acquire or retire for value (including,
         without limitation, in connection with any merger or consolidation
         involving an Issuer) any Equity Interests of the Partnership or of any
         of its Restricted Subsidiaries (other than any such Equity Interests
         owned by the Partnership or any of its Restricted Subsidiaries);

                  (iii) except to the extent permitted in clause (iv) below,
         make any payment on or with respect to, or purchase, redeem, defease or
         otherwise acquire or retire for value any Indebtedness that is pari
         passu with or subordinated to the Notes or the Guarantees (other than
         the Notes or the Guarantees), except (a) a payment of interest or
         principal at the Stated Maturity thereof, (b) a purchase, redemption,
         acquisition or retirement required to be made pursuant to the terms of
         such Indebtedness (including pursuant to an asset sale or change of
         control provision) and (c) any such Indebtedness of the Partnership or
         any Restricted Subsidiary owned by the Partnership or a Restricted
         Subsidiary;

                  (iv) make any Investment other than a Permitted Investment or
         a Permitted Business Investment (all such payments and other actions
         set forth in clauses (i) through (iv) above being collectively referred
         to as "Restricted Payments"),

unless, at the time of and after giving effect to such Restricted Payment, no
Default or Event of Default shall have occurred and be continuing or would occur
as a consequence thereof and either:

                  (A) if the Fixed Charge Coverage Ratio for the Partnership's
         four most recent fiscal quarters for which internal financial
         statements are available is not less than 2.0 to 1.0, such Restricted
         Payment, together with the aggregate amount of all other Restricted
         Payments made by the Partnership and its Restricted Subsidiaries during
         the quarter in which such Restricted Payment is made, is less than the
         sum, without duplication, of (a) Available Cash constituting Cash from


                                       61

<PAGE>

         Operations as of the end of the immediately preceding quarter, plus (b)
         the aggregate net cash proceeds of any (i) substantially concurrent
         capital contribution to the Partnership from any Person (other than a
         Restricted Subsidiary of the Partnership) after the Issue Date, (ii)
         substantially concurrent issuance and sale after the Issue Date of
         Equity Interests (other than Disqualified Equity) of the Partnership or
         from the issuance or sale after the Issue Date of convertible or
         exchangeable Disqualified Equity or convertible or exchangeable debt
         securities of the Partnership that have been converted into or
         exchanged for such Equity Interests (other than Disqualified Equity),
         (iii) to the extent that any Restricted Investment that was made after
         the Issue Date is sold for cash or Cash Equivalents or otherwise
         liquidated or repaid for cash or Cash Equivalents, the lesser of the
         refund of capital or similar payment made in other Cash Equivalents
         with respect to such Restricted Investment (less the cost of such
         disposition, if any) and the initial amount of such Restricted
         Investment (other than to a Restricted Subsidiary of the Partnership),
         plus (c) the net reduction in Investments in Restricted Investments
         resulting from dividends, repayments of loans or advances, or other
         transfers of assets in each case to the Partnership or any of its
         Restricted Subsidiaries from any Person (including, without limitation,
         Unrestricted Subsidiaries) or from redesignations of Unrestricted
         Subsidiaries as Restricted Subsidiaries to the extent such amounts have
         not been included in Available Cash constituting Cash from Operations
         for any quarter commencing on or after the Issue Date (items (b) and
         (c) being referred to as "Incremental Funds"), minus (d) the aggregate
         amount of Incremental Funds previously expended pursuant to this clause
         (A) or clause (B) below; or

                  (B) if the Fixed Charge Coverage Ratio for the Partnership's
         four most recent fiscal quarters for which internal financial
         statements are available is less than 2.0 to 1.0, such Restricted
         Payment, together with the aggregate amount of all other Restricted
         Payments made by the Partnership and its Restricted Subsidiaries during
         the quarter in which such Restricted Payment is made, is less than the
         sum, without duplication, of (a) $60.0 million less the aggregate
         amount of all Restricted Payments made by the Partnership and its
         Restricted Subsidiaries pursuant to this clause (B)(a) during the
         period ending on the last day of the fiscal quarter of the Partnership
         immediately preceding the date of such Restricted Payment and beginning
         on the Issue Date, plus (b) Incremental Funds to the extent not
         previously expended pursuant to this clause (B) or clause (A) above.

For purposes of clauses (A) and (B) above, the term "substantially concurrent"
means that either (x) the offering was consummated within 120 days of the date
of determination or (y) the offering was consummated within 24 months of the
date of determination and the proceeds therefrom were used for the purposes
expressly stated in the documents related thereto and may be traced to such use
by segregating, separating or otherwise specifically identifying the movement of
such proceeds.

         (b) So long as no Default has occurred and is continuing or would be
caused thereby, the preceding provisions of this Section 4.08 shall not
prohibit:

                                       62
<PAGE>

                  (i) the payment by the Partnership or any of its Restricted
         Subsidiaries of any distribution or dividend within 60 days after the
         date of declaration thereof, if at said date of declaration such
         payment would have complied with the provisions of this Indenture;

                  (ii) the redemption, repurchase, retirement, defeasance or
         other acquisition of any pari passu or subordinated Indebtedness of the
         Partnership or any of its Restricted Subsidiaries or of any Equity
         Interests of the Partnership or any of its Restricted Subsidiaries in
         exchange for, or out of the net cash proceeds of, a substantially
         concurrent (a) capital contribution to the Partnership or such
         Restricted Subsidiary from any Person (other than the Partnership or
         another Restricted Subsidiary) or (b) sale (a sale will be deemed
         substantially concurrent if such redemption, repurchase, retirement,
         defeasance or acquisition occurs not more than 120 days after such
         sale) (other than to a Restricted Subsidiary of the Partnership) of (i)
         Equity Interests (other than Disqualified Equity) of the Partnership or
         such Restricted Subsidiary or (ii) Indebtedness that is subordinated to
         the Notes or the Guarantees, provided that such new subordinated
         Indebtedness with respect to the redemption, repurchase, retirement,
         defeasance or other acquisition of pari passu or subordinated
         Indebtedness (W) is subordinated to the same extent as such refinanced
         subordinated Indebtedness, (X) has a Weighted Average Life to Maturity
         of at least the remaining Weighted Average Life to Maturity of the
         refinanced subordinated Indebtedness, (Y) is for the same principal
         amount as either such refinanced subordinated Indebtedness plus
         original issue discount to the extent not reflected therein or the
         redemption or purchase price of such Equity Interests (plus reasonable
         expenses of refinancing and any premiums paid on such refinanced
         subordinated Indebtedness) and (Z) is incurred by the Partnership or
         the Restricted Subsidiary that is the obligor on the Indebtedness so
         refinanced or the issuer of the Equity Interests so redeemed,
         repurchased or retired; provided, however, that the amount of any net
         cash proceeds that are utilized for any such redemption, repurchase or
         other acquisition or retirement shall be excluded or deducted from the
         calculation of Available Cash and Incremental Funds;

                  (iii) the defeasance, redemption, repurchase or other
         acquisition of pari passu or subordinated Indebtedness of the
         Partnership or any Restricted Subsidiary with the net cash proceeds
         from an incurrence of Permitted Refinancing Indebtedness;

                  (iv) the payment of any distribution or dividend by a
         Restricted Subsidiary to the Partnership or to the holders of the
         Equity Interests (other than Disqualified Equity) of such Restricted
         Subsidiary on a pro rata basis;

                  (v) the repurchase, redemption or other acquisition or
         retirement for value of any Equity Interests of the Partnership or any
         of its Restricted Subsidiaries held by any member of the General
         Partner's or the Partnership's or any Restricted Subsidiary's
         management pursuant to any management equity subscription agreement or
         stock option agreement or to satisfy obligations under


                                       63

<PAGE>

         any Equity Interests appreciation rights or option plan or similar
         arrangement; provided that the aggregate price paid for all such
         repurchased, redeemed, acquired or retired Equity Interests shall not
         exceed $5.0 million in any 12-month period; and

                  (vi) any payment by the Partnership pursuant to section 3.1(b)
         of the Management Agreement to compensate for certain tax liabilities
         resulting from certain allocated income.

         In computing the amount of Restricted Payments made for purposes of
Section 4.08(a), Restricted Payments made under clauses (i) (but only if the
declaration of such dividend or other distribution has not been counted in a
prior period) and, to the extent of amounts paid to holders other than the
Partnership or any of its Restricted Subsidiaries, (iv) of this Section 4.08(b)
shall be included, and Restricted Payments made under clauses (ii), (iii), (v)
and (vi) and, except to the extent noted above, (iv) of this Section 4.08(b)
shall not be included. The amount of all Restricted Payments (other than cash)
shall be the fair market value on the date of the Restricted Payment of the
asset(s) or securities proposed to be transferred or issued by the Partnership
or such Restricted Subsidiary, as the case may be, pursuant to the Restricted
Payment. The fair market value of any assets or securities that are required to
be valued by this covenant shall be determined by the Board of Directors of the
General Partner whose resolution with respect thereto shall be delivered to the
Trustee.

SECTION 4.09. INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF DISQUALIFIED EQUITY.

         (a) The Partnership shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt), and the Partnership will not issue any
Disqualified Equity and will not permit any of its Restricted Subsidiaries to
issue any Disqualified Equity; provided, however, that the Partnership and any
Restricted Subsidiary may incur Indebtedness (including Acquired Debt), and the
Partnership and the Restricted Subsidiaries may issue Disqualified Equity, if
the Fixed Charge Coverage Ratio for the Partnership's most recently ended four
full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred
or such Disqualified Equity is issued would have been at least 2.25 to 1.0,
determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred, or the
Disqualified Equity had been issued, at the beginning of such four-quarter
period.

         (b) Notwithstanding the prohibitions of Section 4.09(a), so long as no
Default or Event of Default shall have occurred and be continuing or would be
caused thereby, the Partnership and its Restricted Subsidiaries may incur any of
the following items of Indebtedness (collectively, "Permitted Debt"):

                  (i) the incurrence by the Partnership and any of its
         Restricted Subsidiaries of the Indebtedness under Credit Facilities and
         the guarantees

                                       64

<PAGE>

         thereof; provided that the aggregate principal amount of all
         Indebtedness of the Partnership and the Restricted Subsidiaries
         outstanding under all Credit Facilities after giving effect to such
         incurrence does not exceed $1.2 billion less the aggregate amount of
         all repayments of Indebtedness under a Credit Facility that may have
         been made by the Partnership or any of its Restricted Subsidiaries with
         Net Proceeds from Asset Sales to the extent such repayments constitute
         a permanent reduction of commitments under such Credit Facility;

                  (ii) the incurrence by the Partnership and its Restricted
         Subsidiaries of Existing Indebtedness;

                  (iii) the incurrence by the Partnership and the Subsidiary
         Guarantors of Indebtedness represented by the Notes and the Guarantees
         and the related Obligations;

                  (iv) the incurrence by the Partnership or any of its
         Restricted Subsidiaries of Indebtedness represented by Capital Lease
         Obligations, mortgage financings or purchase money obligation, in each
         case, incurred for the purpose of financing all or any part of the
         purchase price or cost of construction or improvement of property,
         plant or equipment used in the business of the Partnership or such
         Restricted Subsidiary, in an aggregate principal amount not to exceed
         $20.0 million at any time outstanding;

                  (v) the incurrence by the Partnership or any of its Restricted
         Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or
         the net proceeds of which are used to refund, refinance or replace,
         Indebtedness (other than intercompany Indebtedness) that was not
         incurred in violation of this Indenture;

                  (vi) the incurrence by the Partnership or any of its
         Restricted Subsidiaries of intercompany Indebtedness between or among
         the Partnership and any of its Restricted Subsidiaries; provided,
         however, that:

                           (A) if the Partnership or any Subsidiary Guarantor is
                  the obligor on such Indebtedness, such Indebtedness must be
                  expressly subordinated to the prior payment in full in cash of
                  all Obligations with respect to the Notes, in the case of the
                  Partnership, or the Guarantee of such Subsidiary Guarantor, in
                  the case of a Subsidiary Guarantor; and

                           (B) (i) any subsequent issuance or transfer of Equity
                  Interests that results in any such Indebtedness being held by
                  a Person other than the Partnership or a Restricted Subsidiary
                  thereof and (ii) any sale or other transfer of any such
                  Indebtedness to a Person that is not either the Partnership or
                  a Restricted Subsidiary thereof, shall be deemed, in each
                  case, to constitute an incurrence of such Indebtedness by the
                  Partnership or such Restricted Subsidiary, as the case may be,
                  that was not permitted by this clause (vi);


                                       65

<PAGE>

                  (vii) the incurrence by the Partnership or any of its
         Restricted Subsidiaries of Hedging Obligations that are incurred for
         the purpose of fixing or hedging foreign currency exchange rate risk of
         the Partnership or any Restricted Subsidiary or interest rate risk with
         respect to any floating rate Indebtedness of the Partnership or any
         Restricted Subsidiary that is permitted by the terms of this Indenture
         to be outstanding or commodities pricing risks of the Partnership or
         any Restricted Subsidiary in respect of hydrocarbon production from
         properties in which the Partnership or any of its Restricted
         Subsidiaries owns an interest;

                  (viii) the guarantee by the Partnership or any of its
         Restricted Subsidiaries of Indebtedness of the Partnership or a
         Restricted Subsidiary of the Partnership that was permitted to be
         incurred by another provision of this covenant;

                  (ix) bid, performance, surety and appeal bonds incurred in the
         ordinary course of business, including guarantees and standby letters
         of credit supporting such obligations, to the extent not drawn;

                  (x) the incurrence by the Partnership or any of its Restricted
         Subsidiaries of additional Indebtedness in an aggregate principal
         amount (or accreted value, as applicable) at any time outstanding,
         including all Permitted Refinancing Indebtedness incurred to refund,
         refinance or replace any Indebtedness incurred pursuant to this clause
         (x), not to exceed $20.0 million;

                  (xi) the incurrence by the Partnership's Unrestricted
         Subsidiaries of Non-Recourse Debt; provided, however, that if any such
         Indebtedness ceases to be Non-Recourse Debt of an Unrestricted
         Subsidiary, such event shall be deemed to constitute an incurrence of
         Indebtedness by a Restricted Subsidiary of the Partnership that was not
         permitted by this clause (xi);

                  (xii) the payment of interest on any Indebtedness in the form
         of additional Indebtedness with the same terms, and the payment of
         dividends on Disqualified Equity, in the form of additional shares of
         the same class of Disqualified Equity, provided, in each such case,
         that the amount thereof is included in Fixed Charges of the Partnership
         as so accrued, accredited or amortized; and

                  (xiii) Indebtedness incurred by the Partnership or any of its
         Restricted Subsidiaries arising from agreements or their respective
         bylaws providing for indemnification, adjustment of purchase price or
         similar obligations.

         (c) For purposes of determining compliance with this Section 4.09, in
the event that an item of proposed Indebtedness meets the criteria of more than
one of the categories of Permitted Debt described in paragraphs (b)(i) through
(b)(xiii) above, or is entitled to be incurred pursuant to Section 4.09(a), the
Partnership shall be permitted to classify such item of Indebtedness on the date
of its incurrence in any manner that complies with this Section 4.09. An


                                       66
<PAGE>

item of Indebtedness may be divided and classified in one or more of the types
of Permitted Indebtedness.

SECTION 4.10. ANTI-LAYERING.

         The Issuers shall not incur, create, issue, assume, guarantee or
otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to any Senior Debt of either of the Issuers and senior in any
respect in right of payment to the Notes. No Subsidiary Guarantor shall incur,
create, issue, assume, guarantee or otherwise become liable for any Indebtedness
that is subordinate or junior in right of payment to any Senior Debt of such
Subsidiary Guarantor and senior in any respect in right of payment to such
Subsidiary Guarantor's Guarantee.

SECTION 4.11. LIENS.

         The Partnership shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien of any kind securing Indebtedness, Attributable Debt or trade
payables on any asset now owned or hereafter acquired, except Permitted Liens,
without making effective provision whereby all Obligations due under the Notes
and this Indenture or any Guarantee, as applicable, will be secured by a Lien
equally and ratably with any and all Obligations thereby secured for so long as
any such Obligations shall be so secured.

SECTION 4.12. DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

         The Partnership shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any encumbrance or restriction on the ability of any Restricted
Subsidiary to:

         (a) pay dividends or make any other distributions on its Equity
Interests to the Partnership or any of the Partnership's Restricted
Subsidiaries, or with respect to any other interest or participation in, or
measured by, its profits, or pay any indebtedness owed to the Partnership or any
of the other Restricted Subsidiaries;

         (b) make loans or advances to or make other investments in the
Partnership or any of the other Restricted Subsidiaries; or

         (c) transfer any of its properties or assets to the Partnership or any
of the other Restricted Subsidiaries.

The restrictions contained in the immediately preceding sentence will not apply
to encumbrances or restrictions existing under or by reason of:

                  (i) agreements as in effect on the Issue Date and any
         amendments, modifications, restatements, renewals, increases,
         supplements, refundings, replacements or refinancings of any such
         agreements or any Existing Indebtedness to which such agreement
         relates, provided that such amendments,

         modifications, restatements, renewals, increases, supplements,
         refundings, replacements or refinancings are no more restrictive, taken
         as a whole, with respect to such distribution, dividend and other
         payment restrictions and loan or investment restrictions than those
         contained in such agreement, as in effect on the Issue Date;

                  (ii) the Partnership Credit Facility and any amendments,
         modifications, restatements, renewals, increases, supplements,
         refundings, replacements or refinancings thereof, provided that such
         amendments, modifications, restatements, renewals, increases,
         supplements, refundings, replacements or refinancings are no more
         restrictive, taken as a whole, with respect to such distribution,
         dividend and other payment restrictions and loan or investment
         restrictions than those contained in such Credit Facility as in effect
         on the Issue Date;

         of a Person acquired by the Partnership or any of its Restricted
         Subsidiaries as in effect at the time of such acquisition (except to
         the extent such Indebtedness was incurred in connection with or in
         contemplation of such acquisition), which encumbrance or restriction is
         not applicable to any Person, other than such Person, or the property
         or assets of such Person, so acquired, provided that, in the case of
         Indebtedness, such Indebtedness was permitted by the terms of this
         Indenture to be incurred;

                  (vi) customary non-assignment provisions in licenses and
         leases entered in the ordinary course of business and consistent with
         past practices;

                  (vii) purchase money obligations for property acquired in the
         ordinary course of business that impose restrictions on the property so

         described in clauses (a) through (c) of the preceding sentence by such
         Restricted Subsidiary pending its sale or other disposition, provided
         that such sale or disposition is consummated, or such restrictions are
         canceled or terminated or lapse, within 90 days;

                  (ix) Permitted Refinancing Indebtedness, provided that the
         restrictions contained in the agreements governing such Permitted
         Refinancing Indebtedness are no more restrictive, taken as a whole,
         than those contained in the agreements governing the Indebtedness being
         refinanced;

                  (x) Liens securing Indebtedness otherwise permitted to be
         issued pursuant to the provisions of Section 4.11 that limit the right
         of the Partnership or any of its Restricted Subsidiaries to dispose of
         the assets subject to such Lien;

                  (xi) any agreement or instrument relating to any property or
         assets acquired after the Issue Date, so long as such encumbrance or
         restriction relates only to the property or assets so acquired and is
         not and are not created in anticipation of such acquisitions;

                  (xii) any agreement or instrument relating to any Acquired
         Debt of any Restricted Subsidiary at the date on which such Restricted
         Subsidiary was acquired by the Partnership or any Restricted Subsidiary
         (other than the Indebtedness incurred in anticipation of such
         acquisition and provided such encumbrances or restrictions extend only
         to property of such acquired Restricted Subsidiary);

                  (xiii) any agreement or instrument governing Indebtedness
         permitted to be incurred under this Indenture, provided that the terms
         and conditions of any such restrictions and encumbrances, taken as a
         whole, are not materially more restrictive than those contained in this
         Indenture, taken as a whole;

SECTION 4.13. TRANSACTIONS WITH AFFILIATES.

         (a) The Partnership shall not, and shall not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each, an "Affiliate Transaction"), unless:

                  (i) such Affiliate Transaction is on terms that are no less
         favorable to the Partnership or the relevant Restricted Subsidiary than
         those that would have been obtained in a comparable transaction by the
         Partnership or such Restricted Subsidiary with an unrelated Person; and

                  (ii) the Partnership delivers to the Trustee:

                           (A) with respect to any Affiliate Transaction or
                  series of related Affiliate Transactions involving aggregate
                  consideration in excess of $10.0 million but less than or
                  equal to $25.0 million, an Officers'

                  Partner or has been approved by an officer pursuant to a

                  consideration in excess of $25.0 million, (I) a resolution of
                  the Board of Directors of the General Partner set forth in an
                  Officers' Certificate certifying that such Affiliate
                  Transaction complies with this covenant and that such

                  proposed, (b) with respect to assets classified, in accordance
                  with GAAP, as property, plant and equipment on the

                  value determined by such appraiser is a range of values or
                  otherwise inexact, the Board of Directors of the General
                  Partner shall determine the exact fair market value, provided
                  that it shall be within the range so determined by the

                  marketing, hedging, production handling, operating,
                  construction, storage, platform use, or other operational
                  contracts, any such contracts are entered into in the ordinary
                  course of business on terms substantially similar to those
                  contained in similar contracts entered into by the Partnership
                  or any Restricted Subsidiary and third parties or, if none of
                  the Partnership or any Restricted Subsidiary has entered into
                  a similar contract with a third party, that the terms are no
                  less favorable than those available from third parties on an
                  arm's-length basis, as determined by the Board of Directors of
                  the General Partner or (d) in the case of any transaction
                  between the Partnership or any of its Restricted Subsidiaries
                  and any Affiliate thereof in which the Partnership
                  beneficially owns 50% or less of the Voting Stock and one or
                  more Persons not Affiliated with the Partnership beneficially
                  own (together) a percentage of Voting Stock at least equal to
                  the interest in Voting Stock of such Affiliate beneficially
                  owned by the Partnership, a resolution of the Board of
                  Directors of the General Partner set forth in the Officers'
                  Certificate certifying that such Affiliate Transaction
                  complies with this covenant and that such Affiliate
                  Transaction has been approved by a majority of the
                  disinterested members of the Board of Directors of the General
                  Partner. Even though a particular Affiliate Transaction or
                  series of Affiliate Transactions may be covered by two or more
                  of clauses (a)

                                       70


<PAGE>

                  through (d) above, the compliance with any one of such
                  applicable clauses shall be satisfactory.

         (b) The following items shall not be deemed to be Affiliate
Transactions and, therefore, shall not be subject to the provisions of Section
4.13(a):

                  (i) transactions pursuant to the Management Agreement as in
         effect on the date hereof;

                  (ii) any employment, equity option or equity appreciation
         agreement or plan entered into by the Partnership or any of its
         Restricted Subsidiaries in the ordinary course of business and, as
         applicable, consistent with the past practice of the Partnership or
         such Restricted Subsidiary;

                  (iii) transactions between or among the Partnership and/or its
         Restricted Subsidiaries;

                  (iv) Restricted Payments that are permitted by Section 4.08;

                  (v) transactions effected in accordance with the terms of
         agreements as in effect on the Issue Date;

                  (vi) customary compensation, indemnification and other
         benefits made available to officers, directors or employees of the
         Partnership or a Restricted Subsidiary, including reimbursement or
         advancement of out-of-pocket expenses and provisions of officers' and
         directors' liability insurance; and

                  (vii) loans to officers and employees made in the ordinary
         course of business in an aggregate amount not to exceed $1.0 million at
         any one time outstanding.

SECTION 4.14. ADDITIONAL SUBSIDIARY GUARANTEES.

         If the Partnership or any of its Restricted Subsidiaries acquires or
creates another Restricted Subsidiary after the Issue Date that guarantees any
Indebtedness of either of the Issuers, then that newly acquired or created
Restricted Subsidiary must become a Subsidiary Guarantor and execute a
supplemental indenture satisfactory to the Trustee and deliver an Opinion of
Counsel to the Trustee within 10 Business Days of the date on which it was
acquired or created. If a Restricted Subsidiary that is not then a Subsidiary
Guarantor guarantees Indebtedness of either of the Issuers or any other
Restricted Subsidiary, such Restricted Subsidiary shall execute and deliver a
Guarantee. The Partnership will not permit any of its Restricted Subsidiaries,
directly or indirectly, to guarantee or pledge any assets to secure the payment
of any other Indebtedness of either Issuer unless such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture providing for the
guarantee of the payment of the Notes by such Restricted Subsidiary, which
Guarantee shall be senior to or pari passu with such Restricted Subsidiary's
guarantee of or pledge to secure such other Indebtedness, unless such other
Indebtedness is Senior Debt, in which case the Guarantee of the Notes may be
subordinated to the guarantee of such Senior Debt to the same extent as the
Notes

                                       71


<PAGE>

are subordinated to such Senior Debt. Notwithstanding the foregoing, any
Guarantee of a Restricted Subsidiary that was incurred pursuant to this
paragraph shall provide by its terms that it shall be automatically and
unconditionally released upon the release or discharge of the guarantee which
resulted in the creation of such Restricted Subsidiary's Subsidiary Guarantee,
except a discharge or release by, or as a result of payment under, such
guarantee.

SECTION 4.15. DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES.

         The General Partner may designate any Restricted Subsidiary of the
Partnership to be an Unrestricted Subsidiary if that designation would not cause
a Default or Event of Default. If a Restricted Subsidiary is designated as an
Unrestricted Subsidiary, all outstanding Investments owned by the Partnership
and its Restricted Subsidiaries in the Subsidiary so designated will be deemed
to be an Investment made as of the time of such designation and will reduce the
amount available for Restricted Payments under Section 4.08(a), Permitted
Investments or Permitted Business Investments, as applicable. All such
outstanding Investments will be valued at their fair market value, as determined
by the Board of Directors of the General Partner, at the time of such
designation. That designation will only be permitted if such Restricted Payment,
Permitted Investments or Permitted Business Investments would be permitted under
this Indenture at that time and such Restricted Subsidiary otherwise complies
with the definition of an Unrestricted Subsidiary. All Subsidiaries of such an
Unrestricted Subsidiary shall be also thereafter constitute Unrestricted
Subsidiaries. A Subsidiary may not be designated as an Unrestricted Subsidiary
unless at the time of such designation, (x) it has no Indebtedness other than
Non-Recourse Debt; (y) no portion of the Indebtedness or any other obligation of
such Subsidiary (whether contingent or otherwise and whether pursuant to the
terms of such Indebtedness or the terms governing the organization and operation
of such Subsidiary or by law) (A) is guaranteed by the Partnership or any of its
other Restricted Subsidiaries, except as such Indebtedness is permitted by
Sections 4.08 and 4.09, (B) is recourse to or obligates the Partnership or any
of its Restricted Subsidiaries in any way (including any "claw-back",
"keep-well' or "make-well" agreements or other agreements, arrangements or
understandings to maintain the financial performance or results of operations of
such Subsidiary, except as such Indebtedness or Investment is permitted by
Sections 4.08 and 4.09), or (C) subjects any property or assets of the
Partnership or any of its other Restricted Subsidiaries, directly or indirectly,
contingently or otherwise, to the satisfaction thereof; and (z) no Equity
Interests of a Restricted Subsidiary are held by such Subsidiary, directly or
indirectly. Upon the designation of a Restricted Subsidiary that is a Subsidiary
Guarantor as an Unrestricted Subsidiary, the Guarantee of such entity shall be
released and the Trustee shall be authorized to take such actions as may be
appropriate to reflect such release.

         The Board of Directors of the General Partner may redesignate any
Unrestricted Subsidiary to be a Restricted Subsidiary if a Default or Event of
Default is not continuing, the redesignation would not cause a Default or Event
of Default and provided that, if at the time of such designation such Subsidiary
is a Subsidiary Guarantor, after giving effect to such designation, the
Partnership and its remaining Restricted Subsidiaries could incur at least $1.00
of additional Indebtedness under Section 4.09(a).

SECTION 4.16. BUSINESS ACTIVITIES.

         The Partnership shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in any business other than Permitted Businesses.

SECTION 4.17. SALE AND LEASEBACK TRANSACTIONS.

         The Partnership will not, and will not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Partnership or any Restricted Subsidiary that is a Subsidiary Guarantor may
enter into a sale and leaseback transaction if:

         (a) the Partnership or that Subsidiary Guarantor, as applicable, could
have (i) incurred Indebtedness in an amount equal to the Attributable Debt
relating to such sale and leaseback transaction under Section 4.09(a), and (ii)
incurred a Lien to secure such Indebtedness pursuant to Section 4.11; provided,
however, that clause (i) of this clause (a) shall be suspended during any period
in which the Partnership and the Restricted Subsidiaries are not subject to the
Suspended Covenants;

         (b) the gross cash proceeds of that sale and leaseback transaction are
at least equal to the fair market value, as determined in good faith by the
Board of Directors of the General Partner, of the property that is the subject
of such sale and leaseback transaction; and

         (c) the transfer of assets in that sale and leaseback transaction is
permitted by, and the Partnership applies the proceeds of such transaction in
compliance with, Section 4.07.

SECTION 4.18. PAYMENTS FOR CONSENT.

         The Partnership shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly, pay or cause to be paid any consideration to or for
the benefit of any Holder of Notes for or as an inducement to any consent,
waiver or amendment of any of the terms or provisions of this Indenture or the
Notes unless such considerations is offered to be paid and is paid to all
Holders of the Notes that consent, waive or agree to amend in the time frame set
forth in the solicitation documents relating to such consent, waiver or
agreement.

SECTION 4.19. REPORTS.

         (a) Whether or not required by the SEC, so long as any Notes are
outstanding, the Partnership will file with the SEC (unless the SEC will not
accept such a filing) within the time periods specified in the SEC's rules and
regulations and, upon request, the Partnership will furnish the Trustee for
delivery to Holders upon their request:

                  (i) all quarterly and annual financial information that would
         be required to be contained in a filing with the SEC on Forms 10-Q and
         10-K if the Partnership were required to file such Forms, including a
         "Management's Discussion and Analysis of Financial Condition and
         Results of Operations" and, with respect to the annual information
         only, a report on the annual financial statements by the Partnership's
         certified independent accountants; and

                                       73


<PAGE>

                  (ii) all current reports that would be required to be filed
         with the SEC on Form 8-K if the Partnership were required to file such
         reports.

         (b) If at the end of any such quarterly or annual period referred to in
Section 4.19(a), the Partnership has designated any of its Subsidiaries as
Unrestricted Subsidiaries or if the Partnership owns more than 50% of Atlantis
Offshore, L.L.C., Copper Eagle Gas Storage, L.L.C., Deepwater Gateway, L.L.C.
and Poseidon Oil Pipeline Company, L.L.C. but such entity or any of its
Subsidiaries still is designated as a Joint Venture, then the Partnership shall
deliver (promptly after such SEC filing referred to in Section 4.19(a)) to the
Trustee for delivery to the Holders of the Notes quarterly and annual financial
information required by Section 4.19(a) as revised to include a reasonably
detailed presentation, either on the face of the financial statements or in the
footnotes thereto, and in Management's Discussion and Analysis of Financial
Condition and Results of Operations, of the financial condition and results of
operations of the Partnership and its Restricted Subsidiaries separate from the
financial condition and results of operations of the Unrestricted Subsidiaries
of the Partnership and the designated Joint Ventures of the Partnership.

         (c) In addition, whether or not required by the SEC, the Partnership
will make such information available to securities analysts, investors and
prospective investors upon request. In addition, upon request the Partnership
shall furnish the Trustee such other non-confidential information, documents and
other reports which the Partnership is required to file with the SEC pursuant to
Section 13 or Section 15(d) of the Exchange Act.

         (d) For so long as any Series A Notes remain outstanding (unless the
Partnership is subject to the reporting requirements of the Exchange Act), the
Partnership and the Securities Guarantors shall furnish to the Holders thereof,
upon their request, the information required to be delivered pursuant to Rule
144A(d)(4) under the Securities Act to the extent such information is not
provided pursuant to Sections 4.19(a) and 4.19(b).

         (e) Delivery of reports, information and documents to the Trustee
pursuant to this Section 4.19 is for informational purposes only and the
Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Partnership's compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

SECTION 4.20. SUSPENSION OF COVENANTS.

         During any period of time that the Notes have an Investment Grade
Rating from both Rating Agencies and no Default has occurred and is continuing,
the Partnership and the Restricted Subsidiaries shall not be subject to Sections
4.07, 4.08, 4.09, 4.12, 4.13, 4.17(a)(i) and 5.01(a)(iv)(B) (collectively, the
"Suspended Covenants"); provided, however, that if the Partnership and the
Restricted Subsidiaries are not subject to the Suspended Covenants for any
period of time as a result of this Section 4.20 and, subsequently, either of the
Rating Agencies withdraws its ratings or downgrades the ratings assigned to the
Notes below the Investment Grade Ratings so that the Notes do not have an
Investment Grade Rating from both Rating Agencies, or a Default (other than with
respect to the Suspended Covenants) occurs and is continuing, the Issuers and
the Restricted Subsidiaries shall thereafter again be subject to the

                                       74

<PAGE>

Suspended Covenants, subject to the terms, conditions and obligations set forth
in this Indenture (each such date of reinstatement being the "Reinstatement
Date"). Compliance with the Suspended Covenants with respect to Restricted
Payments made after the Reinstatement Date shall be calculated in accordance
with Section 4.08 as though Section 4.08 had been in effect during the entire
period of time from which the Notes are issued.

or merge with or into another Person (whether or not such Issuer is the
survivor); or (y) sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of its properties or assets, in one or more related
transactions, to another Person; unless:

                  (i) either: (A) such Issuer is the surviving entity; or (B)
         the Person formed by or surviving any such consolidation or merger (if
         other than such Issuer) or to which such sale, assignment, transfer,
         lease, conveyance or other disposition shall have been made is an
         entity organized or existing under the laws of the United States, any
         state thereof or the District of Columbia (provided that El Paso
         Finance may not consolidate or merge with or into any entity other than
         a corporation satisfying such requirement for so long as the
         Partnership remains a partnership);

                  (ii) the Person formed by or surviving any such consolidation

                  after the transaction equal to or greater than the
                  Consolidated Net Worth of such Issuer immediately preceding
                  the transaction; and

                           (B) shall, on the date of such transaction after
                  giving pro forma effect thereto and any related financing
                  transactions as if the same had occurred at the beginning of
                  the applicable four-quarter period, be permitted to incur at
                  least $1.00 of additional Indebtedness pursuant to the Fixed

<PAGE>

                  which the Partnership and the Restricted Subsidiaries are not

                           (C) has delivered to the Trustee an Officers'
                  Certificate and an Opinion of Counsel, each stating that such
                  consolidation, merger or transfer and, if a supplemental
                  indenture is required, such supplemental indenture comply with
                  this Indenture and all conditions precedent therein relating
                  to such transaction have been satisfied.

         (b) Notwithstanding Section 5.01(a), the Partnership is permitted to
reorganize as any other form of entity in accordance with the procedures
established in this Indenture; provided that:

                  (i) the reorganization involves the conversion (by merger,
         sale, contribution or exchange of assets or otherwise) of the
         Partnership into a form of entity other than a limited partnership
         formed under Delaware law;

                  (ii) the entity so formed by or resulting from such

         of Default exists; and

         (1) is subject to federal or state income taxation as an entity or (2)
         is considered to be an "includible corporation" of an affiliated group
         of corporations within the meaning of Section 1504(b)(i) of the Code or
         any similar state or local law).

         (c) Section 5.01(a) shall not apply to a merger or consolidation or any
sale, assignment, transfer, lease, conveyance or other disposition of assets
between or among the Partnership and any of its Restricted Subsidiaries.

         (d) No Subsidiary Guarantor may consolidate with or merge with or into
(whether or not such Subsidiary Guarantor is the surviving Person) another
Person, whether or not affiliated with such Subsidiary Guarantor, but excluding
the Partnership or another Subsidiary Guarantor, unless (i) subject to the
provisions of Section 5.01(e), the Person formed by or surviving any such
consolidation or merger (if other than such Subsidiary Guarantor) assumes all
the obligations of such Subsidiary Guarantor pursuant to the Subsidiary
Guarantor's Guarantee of the Notes and the Indenture pursuant to a supplemental
indenture and (ii) immediately after

                                       76

all of the assets of any Subsidiary Guarantor, by way of merger, consolidation
or otherwise, or a sale or other disposition of all or substantially all of the
Equity Interests of any Subsidiary Guarantor, then such Subsidiary Guarantor (in
the event of a sale or other disposition, by way of such a merger, consolidation
or otherwise, of all of the Equity Interests of such Subsidiary Guarantor) or
the Person acquiring the property (in the event of a sale or other disposition
of all or substantially all of the assets of such Subsidiary Guarantor) will be
released and relieved of any obligations under its Guarantee; provided that the
Partnership applies the Net Proceeds of such sale or other disposition in
accordance with the provisions set forth under Sections 3.09 and 4.07.

SECTION 5.02. SUCCESSOR ENTITY SUBSTITUTED.

         (a) Upon any consolidation or merger, or any sale, assignment,
transfer, lease, conveyance or other disposition of all or substantially all of
the assets of an Issuer in accordance with Section 5.01 hereof, the surviving
entity formed by such consolidation or into or with which such Issuer is merged
or to which such sale, assignment, transfer, lease, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, lease, conveyance or other
disposition, the provisions of this Indenture referring to the "Partnership" or
"El Paso Finance," as the case may be, shall refer instead to the surviving
entity and not to the Partnership or El Paso Finance, as the case may be), and
may exercise every right and power of the Partnership or El Paso Finance, as the
case may be, under this Indenture with the same effect as if such successor
Person had been named as an Issuer herein; provided, however, that the
predecessor shall not be relieved from the obligation to pay the principal of
and interest on the Notes except in the case of a sale of all of an Issuer's
assets that meets the requirements of Section 5.01 hereof.

         (b) If the surviving entity shall have succeeded to and been
substituted for an Issuer, such surviving entity may cause to be signed, and may
issue either in its own name or in the name of the applicable Issuer prior to
such succession any or all of the Notes issuable hereunder which theretofore
shall not have been signed by such Issuer and delivered to the Trustee; and,
upon the order of such surviving entity, instead of such Issuer, and subject to
all the terms, conditions and limitations in this Indenture prescribed, the
Trustee shall authenticate and shall deliver any Notes which previously shall
have been signed and delivered by the Officers of such Issuer to the Trustee for
authentication, and any Notes which such surviving entity thereafter shall cause
to be signed and delivered to the Trustee for that purpose (in each instance
with notations of Guarantees thereon by the Subsidiary Guarantors). All of the
Notes so issued and so endorsed shall in all respects have the same legal rank
and benefit under this Indenture as the Notes theretofore or thereafter issued
and endorsed in accordance with the terms of this Indenture and the Guarantees
as though all such Notes had been issued and endorsed at the date of the
execution hereof.

         (c) In case of any such consolidation, merger, continuance, sale,
transfer, conveyance or other disposal, such changes in phraseology and form
(but not in substance) may

                                       77
<PAGE>

be made in the Notes thereafter to be issued or the Guarantees to be endorsed
thereon as may be appropriate.

         (d) For all purposes of this Indenture and the Notes, Subsidiaries of
any surviving entity will, upon such transaction or series of transactions,
become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant
to this Indenture and all Indebtedness, and all Liens on property or assets, of
the surviving entity and its Restricted Subsidiaries immediately prior to such
transaction or series of transactions shall be deemed to have been incurred upon
such transaction or series of transactions.

Liquidated Damages with respect to, the Notes, whether or not prohibited by the
subordination provisions of this Indenture;

         (b) default in payment when due of the principal of or premium, if any,

Indenture;

comply with any of the other agreements in this Indenture for 60 days after
notice to the Issuers by the Trustee or to the Issuers and Trustee by Holders of
at least 25% in aggregate principal amount of the Notes then outstanding
(provided that no such notice need be given, and an Event of Default shall
occur, 60 days after a failure to comply with the covenants in Section 4.08,
4.09 or 5.01 hereof, unless theretofore cured);

         (e) default under any mortgage, indenture or instrument under which
there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by either Issuer or any of the Restricted
Subsidiaries of the Partnership (or the payment of which is guaranteed by either
Issuer or any of such Restricted Subsidiaries), whether such Indebtedness or
guarantee now exists or is created after the date of this Indenture, if that
default:

                  (i) is caused by a failure to pay principal of or premium, if
         any, or interest on such Indebtedness prior to the expiration of the
         grace period provided in such Indebtedness on the date of such default
         (a "Payment Default"); or

                  (ii) results in the acceleration of such Indebtedness prior to
         its express maturity,

                                       78
<PAGE>

and, in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a

Partnership to pay final judgments aggregating in excess of $10.0 million, which
judgments are not paid, discharged or stayed for a period of 60 days;

         (g) except as permitted by this Indenture, any Guarantee shall be held
in any judicial proceeding to be unenforceable or invalid or shall cease for any
reason to be in full force and effect or any Subsidiary Guarantor, or any Person
acting on behalf of any Subsidiary Guarantor, shall deny or disaffirm its
obligations under its Guarantee;

         (h) either Issuer or any Restricted Subsidiary of the Partnership that

                  (ii) consents to the entry of an order for relief against it
         in an involuntary case,

                  (v) generally is not paying its debts as they become due; and

         (i) a court of competent jurisdiction enters an order or decree under
any Bankruptcy Law that:

                  (i) is for relief against an Issuer or any Restricted
         Subsidiary of the Partnership that is a Significant Subsidiary or any
         group of Restricted Subsidiaries of the Partnership that, taken as a

         Subsidiary of the Partnership that is a Significant Subsidiary or any
         group of Restricted Subsidiaries of the Partnership that, taken as a
         whole, would constitute a Significant Subsidiary or for all or
         substantially all of the property of an Issuer or any Restricted
         Subsidiary of the Partnership that is a Significant Subsidiary or any
         group of Restricted Subsidiaries of the Partnership that, taken as a
         whole, would constitute a Significant Subsidiary; or

         Subsidiary of the Partnership that is a Significant Subsidiary or any
         group of Restricted

                                       79
<PAGE>

         Subsidiaries of the Partnership that, taken as a whole, would
         constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days.


SECTION 6.02. ACCELERATION.

         If any Event of Default (other than an Event of Default specified in
clauses (h) or (i) of Section 6.01 hereof) occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable immediately. Upon any such
declaration, the Notes shall become due and payable immediately. Notwithstanding
the foregoing, if an Event of Default specified in clause (h) or (i) of Section
6.01 hereof occurs, all outstanding Notes shall be due and payable immediately
without further action or notice. Notwithstanding the foregoing, so long as any
Credit Facility shall be in full force and effect, if an Event of Default
pursuant to clause (e) of Section 6.01 with regard to such Credit Facility shall
have occurred and be continuing, the Notes shall not become due and payable
until the earlier to occur of (x) five Business Days following delivery of
written notice of such acceleration of the Notes to the agent under such Credit
Facility and (y) the acceleration of any Indebtedness under such Credit
Facility. The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may on behalf of all of the
Holders rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium that has become due solely
because of the acceleration) have been cured or waived.

SECTION 6.03. OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest (and Liquidated Damages, if any) on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04. WAIVER OF PAST DEFAULTS.

         Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and/or interest, if any, or Liquidated
Damages, if any, on, the Notes (including in connection with an offer to
purchase) (provided, however, that the Holders of a majority in aggregate
principal amount of the then outstanding Notes may rescind an acceleration and
its consequences, including any related

                                       80
<PAGE>

payment default that resulted from such acceleration). Upon any such waiver,
such Default shall cease to exist, and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose of this Indenture; but no
such waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

SECTION 6.05. CONTROL BY MAJORITY.

         Holders of a majority in principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

SECTION 6.06. LIMITATION ON SUITS.

         A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

         (a) the Holder of a Note gives to the Trustee written notice of a
continuing Event of Default;

         (b) the Holders of at least 25% in principal amount of the then
outstanding Notes make a written request to the Trustee to pursue the remedy;

         (c) such Holder of a Note or Holders of Notes offer and, if requested,
provide to the Trustee indemnity satisfactory to the Trustee against any loss,
liability or expense;

         (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

         (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Notes do not give the Trustee a direction
inconsistent with the request.

         A Holder of a Note may not use this Indenture to prejudice the rights
of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

SECTION 6.07. RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and interest and
Liquidated Damages, if any, on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

                                       81
<PAGE>

SECTION 6.08. COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover a judgment in its own name
and as trustee of an express trust against the Issuers for the whole amount of
principal of, premium and interest and Liquidated Damages, if any, remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee is authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to an Issuer
or any of the Subsidiary Guarantors (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10. PRIORITIES.

         If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

         First: to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

         Second: subject to the subordination provisions of this Indenture, to
Holders of Notes for amounts due and unpaid on the Notes for principal, premium
and Liquidated Damages, if any, and interest, ratably, without preference or
priority of any kind, according to the amounts

                                       82

<PAGE>

due and payable on the Notes for principal, premium and Liquidated Damages, if
any and interest, respectively; and

         Third: to the Issuers or the Subsidiary Guarantors or to such other
party as a court of competent jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

SECTION 6.11. UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more
than 10% in principal amount of the then outstanding Notes.

                                   ARTICLE 7
                                    TRUSTEE

SECTION 7.01. DUTIES OF TRUSTEE.

         (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

         (b) Except during the continuance of an Event of Default:

                  (i) the duties of the Trustee shall be determined solely by
         the express provisions of this Indenture and the Trustee need perform
         only those duties that are specifically set forth in this Indenture and
         no others, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

                  (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee shall be under a duty to examine
         the same to determine whether or not they conform to the requirements
         of this Indenture (but need not confirm or investigate the accuracy of
         mathematical calculations or other facts stated therein).

                                       83

<PAGE>

         (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                  (i) this paragraph does not limit the effect of paragraph (b)
         of this Section;

                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts; and

                  (iii) the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to any provision of this Indenture
         relating to the time, method and place of conducting any proceeding or
         remedy available to the Trustee, or exercising any trust or power
         conferred upon the Trustee under this Indenture.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section.

         (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability. The Trustee
shall be under no obligation to exercise any of its rights and powers under this
Indenture at the request of any Holders, unless such Holder shall have offered
to the Trustee security and indemnity satisfactory to it against any claim,
loss, liability or expense.

         (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Partnership or El Paso
Finance. Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by law.

SECTION 7.02. RIGHTS OF TRUSTEE.

         (a) Subject to the provisions of Section 7.01(a) hereof, the Trustee
may conclusively rely upon any document believed by it to be genuine and to have
been signed or presented by the proper Person. The Trustee need not investigate
any fact or matter stated in the document.

         (b) Before the Trustee acts or refrains from acting in the
administration of this Indenture, it may require an Officers' Certificate or an
Opinion of Counsel or both. The Trustee shall not be liable for any action it
takes or omits to take in good faith in reliance on such Officers' Certificate
or Opinion of Counsel. The Trustee may consult with counsel of its selection and
the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection from liability in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon.

         (c) The Trustee may execute any of its trusts or powers or perform any
duties under this Indenture either directly by or through agents or attorneys,
and may in all cases pay, subject to reimbursement as provided herein, such
reasonable compensation as it deems proper to

                                       84

<PAGE>

all such agents and attorneys employed or retained by it, and the Trustee shall
not be responsible for any misconduct or negligence of any agent or attorney
appointed with due care.

take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

         (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from an Issuer or any Subsidiary Guarantor

Partner (in the case of the Partnership), by an Officer of the General Partner
(in the case of the General Partner) or by an Officer of El Paso Finance or any
Subsidiary Guarantor (in the case of El Paso Finance or such Subsidiary
Guarantor).

         (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the claims, costs, expenses and
liabilities that might be incurred by it in compliance with such request or
direction.

         (g) The Trustee is not required to make any inquiry or investigation
into facts or matters stated in any document but the Trustee, in its discretion,
may make such further inquiry or investigation into such facts or matters as it
may see fit and, if the Trustee determines to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Issuers.

         (h) The Trustee is not required to take notice or shall not be deemed
to have notice of any Default or Event of Default hereunder except Defaults or
Events of Default under Sections 6.01(a) and 6.01(b) hereof, unless a
Responsible Officer of the Trustee has actual knowledge thereof or has received
notice in writing of such Default or Event of Default from the Issuers or the
Holders of at least 25% in aggregate principal amount of the Notes then
outstanding, and in the absence of any such notice, the Trustee may conclusively
assume that no such Default or Event of Default exists.

         (i) The Trustee is not required to give any bond or surety with respect
to the performance of its duties or the exercise of its powers under this
Indenture.

         (j) In the event the Trustee receives inconsistent or conflicting
requests and indemnity from two or more groups of Holders of Notes, each
representing less than the aggregate principal amount of Notes outstanding
required to take any action hereunder, the Trustee, in its sole discretion may
determine what action, if any, shall be taken.

         (k) The Trustee's immunities and protections from liability and its
right to indemnification in connection with the performance of its duties under
this Indenture shall extend to the Trustee's officers, directors, agents,
attorneys and employees. Such immunities and protections and right to
indemnification, together with the Trustee's right to compensation, shall
survive the Trustee's resignation of removal, the discharge of this Indenture
and final payments of the Notes.

                                       85

<PAGE>

         (l) The permissive right of the Trustee to take actions permitted by
this Indenture shall not be construed as an obligation or duty to do so.

         (m) Except for information provided by the Trustee concerning the
Trustee, the Trustee shall have no responsibility for any information and any
offering memorandum, disclosure material or prospectus distributed with respect
to the Notes.

SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its commercial banking or any other capacity may become
the owner or pledgee of Notes and may otherwise deal with the Issuers, any
Subsidiary Guarantors or any Affiliate of the Partnership with the same rights
it would have if it were not Trustee. Any Affiliate of the Trustee or Agent may
do the same with like rights and duties. However, in the event that the Trustee
acquires any conflicting interest (as defined in the TIA) it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as trustee
or resign. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

SECTION 7.04. TRUSTEE'S DISCLAIMER.

         The Trustee shall not be responsible for and makes no representation as
to the validity or adequacy of this Indenture, the Notes or the Guarantees, it
shall not be accountable for the Issuers' use of the proceeds from the Notes or
any money paid to an Issuer or upon an Issuer's direction under any provision of
this Indenture, it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

SECTION 7.05. NOTICE OF DEFAULTS.

         If a Default or Event of Default known to the Trustee occurs, the
Trustee shall mail to Holders of Notes a notice of the Default or Event of
Default within 90 days after it occurs. Except in the case of a Default or Event
of Default in payment of principal of, premium, if any, or interest or
Liquidated Damages, if any, on any Note, the Trustee may withhold the notice if
and so long as a committee of its Responsible Officers in good faith determines
that withholding the notice is in the interests of the Holders of the Notes.

SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA Section 313(a) (but if no event described
in TIA Section 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted). The Trustee also shall comply
with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports
as required by TIA Section 313(c).

                                       86

<PAGE>

         A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Partnership and filed with the SEC and each stock
exchange on which the Notes are listed in accordance with TIA Section 313(d).
The Issuers shall promptly notify the Trustee when the Notes are listed on any
stock exchange.

SECTION 7.07. COMPENSATION AND INDEMNITY.

         The Issuers and the Subsidiary Guarantors shall pay to the Trustee from
time to time such compensation as shall be agreed upon in writing between the
Issuers and the Trustee for its acceptance of this Indenture and services
hereunder. The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Issuers and the Subsidiary
Guarantors shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

         The Issuers and the Subsidiary Guarantors shall indemnify each of the
Trustee or any successor Trustee against any and all losses, damages, claims,
liabilities or expenses (including reasonable attorneys' fees and expenses)
incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture against either of the Issuers or any
Subsidiary Guarantor (including this Section 7.07) and defending itself against
any claim (whether asserted by an Issuer, any Subsidiary Guarantor, or any
Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such loss, liability or expense may be attributable to its negligence or bad
faith. The Trustee shall notify the Issuers promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Issuers shall not
relieve the Issuers and the Subsidiary Guarantors of their obligations
hereunder. The Issuers and the Subsidiary Guarantors shall defend the claim and
the Trustee shall cooperate in the defense. The Trustee may have separate
counsel and the Issuers and the Subsidiary Guarantors shall pay the reasonable
fees and expenses of such separate counsel. The Issuers and the Subsidiary
Guarantors need not pay for any settlement made without their consent, which
consent shall not be unreasonably withheld.

         The obligations of the Issuers and the Subsidiary Guarantors under this
Section 7.07 shall survive the satisfaction and discharge of this Indenture.

         To secure the Issuers' and the Subsidiary Guarantors' payment
obligations in this Section, the Trustee shall have a Lien (which it may
exercise through right of set-off) prior to the Notes on all money or property
held or collected by the Trustee, except that held in trust to pay principal,
premium, if any, and Liquidated Damages, if any, and interest on particular
Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and

         The Trustee shall comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

SECTION 7.08. REPLACEMENT OF TRUSTEE.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Issuers. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may
remove the Trustee if:

         (a) the Trustee fails to comply with Section 7.10 hereof;

         (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

         (c) a custodian or public officer takes charge of the Trustee or its
property; or

         (d) the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Issuers shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Issuers.

         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuers, any
Subsidiary Guarantor or the Holders of Notes of at least 10% in principal amount
of the then outstanding Notes may petition any court of competent jurisdiction
for the appointment of a successor Trustee.

         If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10, such Holder of a Note may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Issuers' and the Subsidiary Guarantors' obligations
under Section 7.07 hereof shall continue for the benefit of the retiring
Trustee.

SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor
Trustee.

SECTION 7.10. ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trust powers, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50 million
as set forth in its most recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b), provided, however, that there shall be excluded from the
operation of TIA Section 310(b)(l) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Issuers are outstanding if the requirements of such exclusion set forth in
TIA Section 310(b)(l) are met. For purposes of the preceding sentence, the
optional provision permitted by the second sentence of Section 310(b)(9) of the
Trust Indenture Act shall be applicable.

SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUERS.

         The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

Partner (in the case of the Partnership) or of the Board of Directors of El Paso
Finance (in the case of El Paso Finance) evidenced by a resolution set forth in
an Officers' Certificate, at any time, elect to have either Section 8.02 or 8.03
hereof be applied to all outstanding Notes upon compliance with the conditions
set forth below in this Article 8.

SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE.

         Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Issuers and the Subsidiary Guarantors
shall, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be deemed to have been discharged from their respective Obligations and
certain other obligations with respect to all outstanding Notes and Guarantees,
as applicable, on the date the conditions set forth below are satisfied
(hereinafter,

                                       89

<PAGE>

"Legal Defeasance"). For this purpose, Legal Defeasance means that the Issuers
and the Subsidiary Guarantors shall be deemed to have paid and discharged the
entire Indebtedness represented by the outstanding Notes, which shall thereafter
be deemed to be "outstanding" only for the purposes of Section 8.05 hereof and
the other Sections of this Indenture referred to in clauses (a) and (b) of this
sentence below, and to have satisfied all its other obligations under such Notes
and this Indenture (and the Trustee, on demand of and at the expense of the
Issuers, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (a) the rights of Holders of outstanding Notes to receive
solely from the trust fund described in Section 8.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest and Liquidated Damages, if any, on such Notes when such
payments are due (but not the Change of Control Payment or the payment pursuant
to the Asset Sale Offer), (b) the Issuers' obligations with respect to such
Notes under Sections 2.03, 2.04, 2.06, 2.07, 2.10 and 4.02 hereof, (c) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Issuers' and the Subsidiary Guarantors' obligations in connection therewith, (d)
the Issuers' rights of optional redemption and (e) this Article 8. Subject to
compliance with this Article 8, the Issuers may exercise the option under this
Section 8.02 notwithstanding the prior exercise of its option under Section 8.03
hereof.

SECTION 8.03. COVENANT DEFEASANCE.

         Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Issuers and the Subsidiary Guarantors
shall, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be released from its obligations under the covenants contained in
Sections 3.09, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16,
4.17, 4.19 and 5.01(a)(iv) hereof and any covenant added to this Indenture
subsequent to the Issue Date pursuant to Section 9.01 hereof with respect to the
outstanding Notes on and after the date the conditions set forth below are
satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter
be deemed not "outstanding" for the purposes of any direction, waiver, consent
or declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder (it being understood that such Notes shall not
be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes, the Issuers may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 6.01 hereof, but, except as specified
above, the remainder of this Indenture and such Notes shall be unaffected
thereby. In addition, upon the Issuers' exercise under Section 8.01 hereof of
the option applicable to this Section 8.03 hereof, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, Sections 6.01(c) through
6.01(g) hereof shall not constitute Events of Default.

SECTION 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Notes:

for the benefit of the Holders, cash in United States dollars, non-callable U.S.

being defeased to maturity or to a particular redemption date;

ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

         (c) in the case of an election under Section 8.03 hereof, the
Partnership shall have delivered to the Trustee an Opinion of Counsel in the
United States reasonably acceptable to the Trustee confirming that the Holders

6.01(i) hereof are concerned, at any time in the period ending on the 91st day
after the date of deposit;

         (e) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture) to which either of the Issuers or any
Restricted Subsidiary of the Partnership is a party or by which either of the
Issuers or any Restricted Subsidiary of the Partnership is bound;

         (f) the Partnership shall have delivered to the Trustee an Opinion of
Counsel to the effect that after the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights

Certificate stating that the deposit was not made by such Issuer with the intent
of preferring the Holders over any other creditors of such Issuer or the
Subsidiary Guarantors or with the intent of defeating, hindering, delaying or

              OTHER MISCELLANEOUS PROVISIONS.

         Subject to Section 8.06 hereof, all money and non-callable U.S.
Government Obligations (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including either Issuer acting as a
Paying Agent) as the Trustee may determine, to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium, if any, and
interest, and Liquidated Damages, if any, but such money need not be segregated

Issuers any money or non-callable U.S. Government Obligations held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 8.06. REPAYMENT TO ISSUERS.

         Any money deposited with the Trustee or any Paying Agent, or then held

two years after such principal, and premium, if any, interest or Liquidated
Damages, if any, has become due and payable shall, subject to applicable escheat
law, be paid to the Issuers on the request of the Issuers or (if then held by an
Issuer) shall be discharged from such trust; and the Holder of such Note shall
thereafter, as a creditor, look only to the Issuers or Subsidiary Guarantors for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of such Issuer as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Issuers cause to be published once, in The New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such

SECTION 8.07. REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any United States
dollars or U.S. Government Obligations in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Issuers' and the Subsidiary Guarantors' Obligations under
this Indenture, the Notes and the Guarantees, as applicable, shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.02 or
8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 8.02 or 8.03 hereof, as the case may
be; provided, however, that, if the Issuers or the Subsidiary Guarantors make
any payment of principal of, premium, if any, interest or Liquidated Damages, if
any, on any Note following the reinstatement of its Obligations, the Issuers and
the Subsidiary Guarantors shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money held by the Trustee or Paying
Agent.

                                    ARTICLE 9
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF NOTES.

         Notwithstanding Section 9.02 of this Indenture, the Issuers and the
Subsidiary Guarantors and the Trustee may amend or supplement this Indenture,
the Guarantees, or the Notes without the consent of any Holder of a Note:

         (a) to cure any ambiguity, defect or inconsistency;

certificated Notes or to alter the provisions of Article 2 hereof (including the
related definitions) in a manner that does not materially adversely affect any
Holder;

Guarantors' assets pursuant to Article 5 hereof;

         (d) to add or release Subsidiary Guarantors pursuant to the terms of
this Indenture;

         (e) to make any change that would provide any additional rights or
benefits to the Holders of the Notes or surrender any right or power conferred
upon the Issuers or the Subsidiary Guarantors by the Indenture that does not
adversely affect the legal rights hereunder of any Holder of the Notes; or

         (f) to comply with requirements of the SEC in order to effect or
maintain the qualification of this Indenture under the TIA;

         (g) to evidence or provide for the appointment under this Indenture of
a successor Trustee;

                                       93

<PAGE>

         (h) to add additional Events of Default; or

         (i) to secure the Notes and/or the Guarantees.

         Upon the request of the Issuers accompanied by a resolution of the
Board of Directors of the General Partner (in the case of the Partnership), and
of the Board of Directors of El Paso Finance and each of the Subsidiary
Guarantors (in the case of El Paso Finance and the Subsidiary Guarantors),
authorizing the execution of any such amended or supplemental Indenture, and
upon receipt by the Trustee of the documents described in Section 9.06 hereof,
the Trustee shall join with the Issuers and each of the Subsidiary Guarantors in
the execution of any amended or supplemental Indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02. WITH CONSENT OF HOLDERS OF NOTES.

         Except as provided below in this Section 9.02, the Issuers, the
Subsidiary Guarantors and the Trustee may amend or supplement this Indenture
(including Sections 3.09, 4.06 and 4.07 hereof), the Guarantees, and the Notes
with the consent of the Holders of at least a majority in principal amount of
the Notes then outstanding (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, the
Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on the Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture, the Guarantees or the Notes may be waived
with the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including consents obtained in connection with a tender offer
or exchange offer for the Notes).

         Upon the request of the Issuers accompanied by a resolution of the
Board of Directors of the General Partner (in the case of the Partnership) and

Guarantors (in the case of El Paso Finance and each of the Subsidiary
Guarantors) authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 9.06 hereof, the Trustee shall
join with the Issuers and each of the Subsidiary Guarantors in the execution of
such amended or supplemental Indenture unless such amended or supplemental
Indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

         It shall not be necessary for the consent of the Holders of Notes under
this Section 9.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

                                       94

<PAGE>

         After an amendment, supplement or waiver under this Section becomes
effective, the Issuers shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuers to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding may waive
compliance in a particular instance by the Issuers with any provision of this
Indenture or the Notes. However, without the consent of each Holder affected, an
amendment or waiver may not (with respect to any Notes held by a non-consenting
Holder):

         (a) reduce the principal amount of Notes whose Holders must consent to
an amendment, supplement or waiver;

         (b) reduce the principal of or change the fixed maturity of any Note or
alter or waive any of the provisions with respect to the redemption of the
Notes, except as provided above with respect to Sections 3.09, 4.06 and 4.07
hereof;

         (c) reduce the rate of or change the time for payment of interest,
including default interest, on any Note;

         (d) waive a Default or Event of Default in the payment of principal of
or premium, if any, interest or Liquidated Damages, if any, on the Notes (except
a rescission of acceleration of the Notes by the Holders of at least a majority
in aggregate principal amount of the then outstanding Notes and a waiver of the
payment default that resulted from such acceleration);

         (e) make any Note payable in money other than that stated in the Notes;

         (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Notes to receive payments
of principal of or premium, if any, or interest on the Notes;

         (g) waive a redemption payment with respect to any Note (other than a
payment required by the covenants contained in Sections 3.09, 4.06 or 4.07
hereof;

         (h) except as otherwise permitted by this Indenture, release any
Subsidiary Guarantor from any of its obligations under its Guarantee or this
Indenture, or change any Guarantee in any manner that would adversely affect the
right of Holders; or

         (i) make any change in Section 6.04 or 6.07 hereof or in the foregoing
amendment and waiver provisions (except to increase any percentage set forth
therein).

         In addition, any amendment to the provisions of Article 10 or Section
11.07 of this Indenture (which relate to subordination) shall require the
consent of the Holders of at least 75% in aggregate principal amount of the
Notes then outstanding if such amendment would adversely affect the rights of
Holders of Notes.

SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment or supplement to this Indenture, the Guarantees, or the
Notes shall be set forth in an amended or supplemental Indenture that complies
with the TIA as then in effect.

SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

SECTION 9.05. NOTATION ON OR EXCHANGE OF NOTES.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Issuers in
exchange for all Notes may issue and the Trustee shall authenticate new Notes
(accompanied by a notation of the Guarantees duly endorsed by the Subsidiary
Guarantors) that reflect the amendment, supplement or waiver.

         Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Issuers
and the Subsidiary Guarantors may not sign an amendment or supplemental
Indenture until the Board of Directors of the General Partner approves it. In
executing any amended or supplemental indenture, the Trustee shall be entitled
to receive and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate of the Board of Directors of the General Partner
and an Opinion of Counsel stating that the execution of such amended or
supplemental indenture is authorized or permitted by this Indenture.

SECTION 9.07. EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article 9,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Notes theretofore or thereafter authenticated and delivered hereunder shall
be bound thereby. After a supplemental indenture becomes effective, the Issuers
shall mail to Holders a notice briefly describing such amendment. The failure to
give such notice to all Holders, or any defect therein, shall not impair or
affect the validity of an amendment under this Section.

         The Issuers covenant and agree, and each Holder by accepting a Note
agrees, that the Indebtedness evidenced by, and any Liquidated Damages and other
Obligations with respect to, the Notes are subordinated in right of payment, to
the extent and in the manner provided in this Article 10, to the prior payment
in full in cash of all Senior Debt (whether outstanding on the date hereof or
hereafter created, incurred, assumed or guaranteed), and that the subordination
is for the benefit of the holders of Senior Debt.

SECTION 10.02. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         Upon any payment or distribution to creditors of either of the Issuers
or any Subsidiary Guarantor in a liquidation or dissolution of such Issuer or
such Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to such Issuer or such Subsidiary
Guarantor or its property, in an assignment for the benefit of creditors or any
marshaling of such Issuer's or such Subsidiary Guarantor's assets and
liabilities:

         (a) holders of Senior Debt shall be entitled to receive payment in full
in cash of all Obligations in respect of Senior Debt (including interest after
the commencement of any such proceeding at the rate specified in the applicable
Senior Debt, whether or not such interest would be an allowed claim in such
proceeding) before Holders of the Notes shall be entitled to receive any payment
with respect to the Notes (except that Holders may receive and retain (i)
Permitted Junior Securities and (ii) payments and other distributions made from
any defeasance trust created pursuant to Article 8 hereof, provided that the
funding of such trust was permitted); and

         (b) until all Obligations with respect to Senior Debt (as provided in
subsection (a) above) are paid in full in cash, any payment or distribution to
which Holders would be entitled but for this Article 10 shall be made to holders
of Senior Debt (except that Holders of Notes may receive and retain (i)
Permitted Junior Securities and (ii) payments and other distributions made from
any defeasance trust created pursuant to Article 8 hereof, provided that the
funding of such trust was permitted), as their interests may appear.

SECTION 10.03. DEFAULT ON DESIGNATED SENIOR DEBT.

         The Issuers and the Subsidiary Guarantors may not make any payment or
distribution in respect of Obligations with respect to the Notes (whether by
redemption, purchase, defeasance or otherwise) and may not acquire any Notes for
cash or property (other than (i) Permitted Junior Securities and (ii) payments
and other distributions made from any defeasance trust created pursuant to
Article 8 hereof, provided that the funding of such trust was permitted) until
all principal and other Obligations with respect to the Senior Debt have been
paid in full in cash if:

         (a) a default in the payment of any principal, premium, if any, or
interest (and other Obligations in the case of the Credit Facilities) on
Designated Senior Debt occurs and is continuing; or

                                       97

<PAGE>

         (b) any other default on Designated Senior Debt occurs and is
continuing that permits holders of the Designated Senior Debt to accelerate its
maturity and the Trustee receives a notice of the default (a "Payment Blockage
Notice") from a Person who may give it pursuant to Section 10.11 hereof. If the
Trustee receives any such Payment Blockage Notice, no subsequent Payment
Blockage Notice shall be effective for purposes of this Section unless and until
at least 360 days shall have elapsed since the effectiveness of the immediately
prior Payment Blockage Notice. No nonpayment default that existed or was
continuing on the date of delivery of any Payment Blockage Notice to the Trustee
shall be, or be made, the basis for a subsequent Payment Blockage Notice unless
such default shall have been cured or waived for a period of not less than 120
days.

         The Issuers may and shall resume payments on and distributions in
respect of the Notes and may acquire them upon the earlier of:

         (a) in the case of a default referred to in clause (a) of the
immediately preceding paragraph, the date upon which the default is cured or
waived, or

         (b) in the case of a default referred to in clause (b) of the
immediately preceding paragraph, the earlier of the date on which such
non-payment default is cured or waived and 179 days after the date on which the
applicable Payment Blockage Notice is received by the Trustee unless the
maturity of such Designated Senior Debt has been accelerated,

if this Article 10 otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

SECTION 10.04. ACCELERATION OF NOTES.

         If payment of the Notes is accelerated because of an Event of Default,
the Issuers shall promptly notify holders of Senior Debt of the acceleration.

SECTION 10.05. WHEN DISTRIBUTION MUST BE PAID OVER.

         In the event that the Trustee or any Holder receives any payment of or
distribution with respect to any Obligations with respect to the Notes at a time
when such payment or distribution is prohibited by Section 10.02 or 10.03
hereof, such payment or distribution shall be held by the Trustee or such
Holder, in trust for the benefit of, and shall be paid forthwith over and
delivered, upon written request, to, the holders of Designated Senior Debt as
their interests may appear or their Representative under this Indenture or other
agreement (if any) pursuant to which such Designated Senior Debt may have been
issued, as their respective interests may appear, for application to the payment
in cash of all Obligations with respect to such Designated Senior Debt remaining
unpaid to the extent necessary to pay such Obligations in full in cash in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of such Designated Senior Debt.

         With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article 10, and no implied covenants or obligations with respect
to the holders of Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the

                                       98

<PAGE>

holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Issuers
or any other Person money or assets to which any holders of Senior Debt shall be
entitled by virtue of this Article 10, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

SECTION 10.06. NOTICE BY ISSUERS.

         The Issuers shall promptly notify the Trustee and the Paying Agent of
any facts known to the Issuers that would cause a payment of any Obligations
with respect to the Notes to violate this Article 10, but failure to give such
notice shall not affect the subordination of the Notes to the Senior Debt as
provided in this Article 10.

SECTION 10.07. SUBROGATION.

         After all Senior Debt is paid in full in cash and until the Notes are
paid in full, Holders of Notes shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Notes) to the rights of holders of Senior
Debt to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders of Notes have been applied to the
payment of Senior Debt. A distribution made under this Article 10 to holders of
Senior Debt that otherwise would have been made to Holders of Notes is not, as
between the Issuers and Holders, a payment by the Issuers on the Notes.

SECTION 10.08. RELATIVE RIGHTS.

         This Article 10 defines the relative rights of Holders of Notes and
holders of Senior Debt. Nothing in this Indenture shall:

         (a) impair, as between the Issuers and Holders of Notes, the obligation
of the Issuers, which is absolute and unconditional, to pay principal of and
interest on the Notes in accordance with their terms;

         (b) affect the relative rights of Holders of Notes and creditors of the
Issuers other than their rights in relation to holders of Senior Debt; or

         (c) subject to Section 6.02, prevent the Trustee or any Holder of Notes
from exercising its available remedies upon a Default or Event of Default,
subject to the rights of holders and owners of Senior Debt to receive
distributions and payments otherwise payable to Holders of Notes.

         If the Issuers fail because of this Article 10 to pay principal of or
interest on a Note on the due date, the failure is still a Default or Event of
Default.

SECTION 10.09. SUBORDINATION MAY NOT BE IMPAIRED BY ISSUERS.

         No right of any holder of Senior Debt to enforce the subordination of
the Indebtedness evidenced by the Notes shall be impaired by any act or failure
to act by either of the Issuers or any Holder or by the failure of either of the
Issuers or any Holder to comply with this Indenture.

                                       99

<PAGE>

SECTION 10.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

         Whenever a payment or distribution is to be made or a notice given to
holders of Senior Debt, the payment or distribution may be made and the notice
given to their Representative.

         Upon any payment or distribution of assets of either of the Issuers or
any of the Subsidiary Guarantors referred to in this Article 10, the Trustee and
the Holders of Notes shall be entitled to rely upon any order or decree made by
any court of competent jurisdiction or upon any certificate of such
Representative or of the liquidating trustee or agent or other Person making any
distribution to the Trustee or to the Holders of Notes for the purpose of
ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Debt and other Indebtedness of such Issuer or Subsidiary
Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 10.

SECTION 10.11. RIGHTS OF TRUSTEE AND PAYING AGENT.

         Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless a Responsible Officer of the Trustee shall
have received at its Corporate Trust Office at least two Business Days prior to
the date of such payment written notice of facts that would cause the payment of
any Obligations with respect to the Notes to violate this Article 10. Only the
Issuers or the holders of Designated Senior Debt or their Representative may
give the notice. Nothing in this Article 10 shall impair the claims of, or
payments to, the Trustee under or pursuant to Section 7.07 hereof. Each Paying
Agent shall be subject to the same obligations under this Article 10 as is the
Trustee.

         The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee. Any Affiliate of
the Trustee or Agent may do the same with like rights.

SECTION 10.12. AUTHORIZATION TO EFFECT SUBORDINATION.

         Each Holder of Notes, by the Holder's acceptance thereof, authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the Representative of the Designated Senior Debt are hereby
authorized to file an appropriate claim for and on behalf of the Holders of the
Notes.

SECTION 10.13. AMENDMENTS.

         The provisions of this Article 10 shall not be amended or modified
without the written consent of the holders of all Designated Senior Debt.

                                   GUARANTEES

SECTION 11.01. GUARANTEES.

         Subject to the provisions of this Article 11, each of the Subsidiary
Guarantors hereby, jointly and severally, unconditionally guarantees to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, irrespective of the validity and enforceability
of this Indenture, the Notes or the Obligations of the Issuers hereunder or
thereunder, that: (a) the principal of, premium, interest and Liquidated
Damages, if any, on the Notes shall be promptly paid in full when due, whether
at the maturity or interest payment or mandatory redemption date, by
acceleration, redemption or otherwise, and interest on the overdue principal of,
premium, interest and Liquidated Damages, if any, on the Notes, if any, if
lawful, and all other Obligations of the Issuers to the Holders or the Trustee
under this Indenture and the Notes shall be promptly paid in full or performed,
all in accordance with the terms of this Indenture and the Notes; and (b) in
case of any extension of time of payment or renewal of any Notes or any of such
other obligations, that same shall be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, whether at
Stated Maturity, by acceleration or otherwise. Failing payment when due of any
amount so guaranteed or any performance so guaranteed for whatever reason, the
Subsidiary Guarantors shall be jointly and severally obligated to pay the same
immediately. The Subsidiary Guarantors hereby agree that to the fullest extent
permitted by applicable law, their obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this
Indenture, the absence of any action to enforce the same, any waiver or consent
by any Holder of the Notes with respect to any provisions of this Indenture and
the Notes, the recovery of any judgment against the Issuers, any action to
enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a Subsidiary Guarantor. To the
fullest extent permitted by applicable law, each Subsidiary Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of insolvency or bankruptcy of the Issuers, any right to require a
proceeding first against the Issuers, protest, notice and all demands whatsoever
and covenant that the Guarantees shall not be discharged except by complete
performance of the obligations contained in the Notes and this Indenture.

         If any Holder or the Trustee is required by any court or otherwise to
return to the Issuers or Subsidiary Guarantors, or any custodian, trustee,
liquidator or other similar official acting in relation to either the Issuers or
Subsidiary Guarantors, any amount paid by either to the Trustee or such Holder,
these Guarantees, to the extent theretofore discharged, shall be reinstated in
full force and effect. Each Subsidiary Guarantor agrees that it shall not be
entitled to any right of subrogation in relation to the Holders in respect of
any Obligations guaranteed hereby until payment in full of all Obligations
guaranteed hereby.

         Each Subsidiary Guarantor further agrees that, as between the
Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the
other hand, (x) the maturity of the Obligations guaranteed hereby may be
accelerated as provided in Article 6 hereof for the purposes of these
Guarantees, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Obligations guaranteed hereby, and (y) in
the event

                                       101

<PAGE>

of any declaration of acceleration of such Obligations as provided in Article 6
hereof, such Obligations (whether or not due and payable) shall forthwith become
due and payable by the Subsidiary Guarantors for the purpose of these
Guarantees. The Subsidiary Guarantors shall have the right to seek contribution
from any non-paying Subsidiary Guarantor so long as the exercise of such right
does not impair the rights of the Holders under these Guarantees.

SECTION 11.02. LIMITATION OF GUARANTOR'S LIABILITY.

         Each Subsidiary Guarantor and, by its acceptance hereof, each Holder
hereby confirms that it is its intention that the Guarantee by such Subsidiary
Guarantor not constitute a fraudulent transfer or conveyance for purposes of the
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal or state law to the extent applicable to the
Guarantees. To effectuate the foregoing intention, each such Person hereby
irrevocably agrees that the Obligation of such Subsidiary Guarantor under its
Guarantee under this Article 11 shall be limited to the maximum amount as shall,
after giving effect to such maximum amount and all other (contingent or
otherwise) liabilities of such Subsidiary Guarantor that are relevant under such
laws, and after giving effect to any rights to contribution of such Subsidiary
Guarantor pursuant to any agreement providing for an equitable contribution
among such Subsidiary Guarantor and other Affiliates of the Issuers of payments
made by guarantees by such parties, result in the Obligations of such Subsidiary
Guarantor in respect of such maximum amount not constituting a fraudulent
conveyance. Each Holder, by accepting the benefits hereof, confirms its
intention that, in the event of bankruptcy, reorganization or other similar
proceeding of either of the Issuers or any Subsidiary Guarantor in which
concurrent claims are made upon such Subsidiary Guarantor hereunder, to the
extent such claims shall not be fully satisfied, each such claimant with a valid
claim against such Issuer shall be entitled to a ratable share of all payments
by such Subsidiary Guarantor in respect of such concurrent claims.

SECTION 11.03. EXECUTION AND DELIVERY OF GUARANTEES.

         To evidence the Guarantees set forth in Section 11.01 hereof, each
Subsidiary Guarantor hereby agrees that a notation of the Guarantees
substantially in the form of Exhibit D shall be endorsed by an Officer of such
Subsidiary Guarantor on each Note authenticated and delivered by the Trustee and
that this Indenture shall be executed on behalf of such Subsidiary Guarantor by
its President or one of its Vice Presidents.

         Each Subsidiary Guarantor hereby agrees that the Guarantees set forth
in Section 11.01 shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of the Guarantees.

         If an Officer or Officer whose signature is on this Indenture or on the
Guarantees no longer holds that office at the time the Trustee authenticates the
Note on which the notation of the Guarantees are endorsed, the Guarantees shall
be valid nevertheless.

         The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantees set forth in
this Indenture on behalf of the Subsidiary Guarantors.

SECTION 11.04. SUBSIDIARY GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

         (a) Except as set forth in Articles 4 and 5 hereof, nothing contained
in this Indenture or in any of the Notes shall prevent any consolidation or
merger of the Partnership or a Subsidiary Guarantor with or into the Partnership
or another Subsidiary Guarantor or shall prevent any sale or conveyance of the
property of a Subsidiary Guarantor as an entirety or substantially as an
entirety, to the Partnership or another Subsidiary Guarantor.

         (b) Except as set forth in Articles 4 and 5 hereof, nothing contained
in this Indenture or in any of the Notes shall prevent any consolidation or
merger of a Subsidiary Guarantor with or into another Person other than the
Partnership or another Subsidiary Guarantor (whether or not affiliated with the
Subsidiary Guarantor), or successive consolidations or mergers in which a
Subsidiary Guarantor or its successor or successors shall be a party or parties,
or shall prevent any sale or conveyance of the property of a Subsidiary
Guarantor as an entirety or substantially as an entirety, to a person other than
the Partnership (whether or not affiliated with the Subsidiary Guarantor)
authorized to acquire and operate the same; provided, however, that such
transaction meets all of the following requirements: (i) each Subsidiary
Guarantor hereby covenants and agrees that, upon any such consolidation, merger,
sale or conveyance, the Guarantee contained herein, and the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed by such Subsidiary Guarantor, shall be expressly
assumed (in the event that the Subsidiary Guarantor is not the surviving
corporation in the merger or consolidation), by supplemental indenture
satisfactory in form to the Trustee, executed and delivered to the Trustee, by
the Person formed by such consolidation, or into which the Subsidiary Guarantor
shall have been merged, or by the Person which shall have acquired such
property, and (ii) immediately after giving effect to such transaction, no
Default or Event of Default exists. In case of any such consolidation, merger,
sale or conveyance and upon the assumption by the successor Person by
supplemental indenture, executed and delivered to the Trustee and satisfactory
in form to the Trustee, of the Guarantees contained herein and the due and
punctual performance of all of the covenants and conditions of this Indenture to
be performed by the Subsidiary Guarantor, such successor shall succeed to and be
substituted for the Subsidiary Guarantor with the same effect as if it had been
named herein as a Subsidiary Guarantor. Such successor thereupon may cause to be
signed any or all of the notations of the Guarantees to be endorsed upon all of
the Notes issuable hereunder which theretofore shall not have been signed by the
Issuers and delivered to the Trustee. All the Guarantees so issued shall in all
respects have the same legal rank and benefit under this Indenture as the
Guarantees theretofore and thereafter issued in accordance with the terms of
this Indenture as though all of such Guarantees had been issued at the date of
the execution hereof.

SECTION 11.05. RELEASES.

         Concurrently with any sale of assets (including, if applicable, all of
the Equity Interests of any Subsidiary Guarantor), any Liens in favor of the
Trustee in the assets sold thereby shall be released; provided that in the event
of an Asset Sale, the Net Proceeds from such sale or other disposition are
treated in accordance with the provisions of Section 4.07 hereof. The Guarantee
or the obligations under Section 11.04 hereof of a Subsidiary Guarantor will be
released (i) in connection with any sale or other disposition of all or
substantially all of the assets

                                       103

<PAGE>

of such Subsidiary Guarantor (including by way of merger or consolidation), if
the Partnership applies the Net Proceeds of that sale or other disposition in
accordance with Section 4.07 hereof; or (ii) in connection with the sale or
other disposition of all of the Equity Interests of a Subsidiary Guarantor, if
the Partnership applies the Net Proceeds of that sale in accordance with Section
4.07 hereof; or (iii) if the Partnership designates any Restricted Subsidiary
that is a Subsidiary Guarantor as an Unrestricted Subsidiary; or (iv) at such
time as such Subsidiary Guarantor ceases to guarantee any other Indebtedness of
the Partnership. Upon delivery by the Partnership to the Trustee of an Officers'
Certificate to the effect that such sale or other disposition was made by the
Partnership in accordance with the provisions of this Indenture, including
without limitation Section 4.07 hereof or such Guarantee is to be released
pursuant to the provisions of the immediately preceding sentence, the Trustee
shall execute any documents reasonably required in order to evidence the release
of any Subsidiary Guarantor from its obligations under its Guarantees. Any
Subsidiary Guarantor not released from its obligations under its Guarantee shall
remain liable for the full amount of principal of and interest on the Notes and
for the other obligations of any Subsidiary Guarantor under this Indenture as
provided in this Article 11.

SECTION 11.06. "TRUSTEE" TO INCLUDE PAYING AGENT.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Issuers and be then acting hereunder, the term "Trustee"
as used in this Article 11 shall in such case (unless the context shall
otherwise require) be construed as extending to and including such Paying Agent
within its meaning as fully and for all intents and purposes as if such Paying
Agent were named in this Article 11 in place of the Trustee.

SECTION 11.07. SUBORDINATION OF GUARANTEES.

         The obligations of each Subsidiary Guarantor under its Guarantee
pursuant to this Article 11 shall be junior and subordinated to the prior
payment in full in cash of all Senior Debt and Guarantor Senior Debt (including
interest after the commencement of any proceeding of the type described in
Section 10.02 with respect to such Subsidiary Guarantor at the rate specified in
the applicable Guarantor Senior Debt, whether or not such interest would be an
allowed claim in such proceeding) of such Subsidiary Guarantor, in each case on
the same basis as the Notes are junior and subordinated to Senior Debt, mutatis
mutandis. For the purposes of the foregoing sentence, the Trustee and the
Holders shall have the right to receive and/or retain payments by any of the
Subsidiary Guarantors only at such times as they may receive and/or retain
payments and distributions in respect of the Notes pursuant to this Indenture,
including Article 10 hereof.

                           SATISFACTION AND DISCHARGE

SECTION 12.01. SATISFACTION AND DISCHARGE.

         This Indenture shall upon the request of the Issuers cease to be of
further effect (except as to surviving rights of registration of transfer or
exchange of Notes herein expressly provided for, the Issuers' obligations under
Section 7.07 hereof, the Issuers' rights of optional redemption under Article 3
hereof, and the Trustee's and the Paying Agent's obligations under

<PAGE>

Section 12.02 and 12.03 hereof) and the Trustee, at the expense of the Issuers,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture when

         (a) either

                  (i) all Notes therefore authenticated and delivered (other
         than (A) Notes which have been destroyed, lost or stolen and which have
         been replaced or paid as provided in Section 2.07 and (B) Notes for
         whose payment money has been deposited in trust with the Trustee or any
         Paying Agent and thereafter paid to the Issuers or discharged from such
         trust) have been delivered to the Trustee for cancellation; or

                  (ii) all such Notes not theretofore delivered to the Trustee
         for cancellation

                           (A) have become due and payable; or

                           (B) shall become due and payable at their Stated
                  Maturity within one year, or

                           (C) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Issuers,

         and the Issuers, in the case of clause (A), (B) or (C) above, have
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust for such purpose money or U.S. Government
         Obligations in an amount sufficient (as certified by an independent
         public accountant designated by the Issuers) to pay and discharge the
         entire indebtedness of such Notes not theretofore delivered to the
         Trustee for cancellation, for principal (and premium, if any) and
         interest, if any, to the date of such deposit (in the case of Notes
         which have become due and payable) or the Stated Maturity or redemption
         date, as the case may be;

         (b) the Issuers have paid or caused to be paid all other sums then due
and payable hereunder by the Issuers;

         (c) no Default or Event of Default with respect to the Notes shall have
occurred and be continuing on the date of such deposit and after giving effect
to such deposit; and

         (d) the Issuers have delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
Issuers' obligations in Sections 2.03, 2.04, 2.06, 2.07, 2.11, 7.07, 7.08,
12.02, 12.03 and 12.04, and the Trustee's and Paying Agent's obligations in
Section 12.03 shall survive until the Notes are no longer outstanding.
Thereafter, only the Issuers' obligations in Section 12.03 shall survive.

<PAGE>

         In order to have money available on a payment date to pay principal
(and premium, if any, on) or interest on the Notes, the U.S. Government
Obligations shall be payable as to principal (and premium, if any) or interest
at least one Business Day before such payment date in such amounts as shall
provide the necessary money. The U.S. Government Obligations shall not be
callable at the issuer's option.

SECTION 12.02. APPLICATION OF TRUST.

         All money deposited with the Trustee pursuant to Section 12.01 shall be
held in trust and, at the written direction of the Issuers, be invested prior to
maturity in non-callable U.S. Government Obligations, and applied by the Trustee
in accordance with the provisions of the Notes and this Indenture, to the
payment, either directly or through any Paying Agent as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for the payment of which money has been deposited with the
Trustee; but such money need not be segregated from other funds except to the
extent required by law.

SECTION 12.03. REPAYMENT OF THE ISSUERS.

         The Trustee and the Paying Agent shall promptly pay to the Issuers upon
written request any excess money or securities held by them at any time.

         The Trustee and the Paying Agent shall notify the Issuers of, and pay
to the Issuers upon written request, any money held by them for the payment of
principal or interest that remains unclaimed for two years after the date upon
which such payment shall have become due; provided that the Issuers shall have
either caused notice of such payment to be mailed to each Holder of the Notes
entitled thereto no less than 30 days prior to such repayment or within such
period shall have published such notice in a financial newspaper of widespread
circulation published in The City of New York, including, without limitation,
The Wall Street Journal (national edition). After payment to the Issuers,
Holders entitled to the money must look to the Issuers for payment as general
creditors unless an applicable abandoned property law designates another Person,
and all liability of the Trustee and such Paying Agent with respect to such
money shall cease. In the absence of a written request from the Issuers to
return unclaimed funds to the Issuers, the Trustee shall from time to time
deliver all unclaimed funds to or as directed by applicable escheat authorities,
as determined by the Trustee in its sole discretion, in accordance with the
customary practices and procedures of the Trustee. Any unclaimed funds held by
the Trustee pursuant to this Section 12.03 shall be held uninvested and without
any liability for interest.

SECTION 12.04. REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 12.01 by reason of any legal
proceeding or by reason of any order or judgment of any court of governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Issuers' and Subsidiary Guarantors' Obligations under this Indenture, the Notes
and the Guarantees shall be revived and reinstated as though no deposit has
occurred pursuant to Section 12.01 until such time as the Trustee or Paying
Agent is permitted to apply all such money or U.S. Government Obligations in
accordance with Section 12.02,

                                       106

<PAGE>

provided, however, that if the Issuers or the Subsidiary Guarantors have made
any payment of interest on or principal of any Notes because of the
reinstatement of their Obligations, the Issuers or such Subsidiary Guarantors
shall be subrogated to the rights of the Holders of such Notes to receive such
payment from the money or U.S. Government Obligations held by the Trustee or
Paying Agent.

SECTION 13.04. CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

         Upon any request or application by the Issuers or any Subsidiary
Guarantor to the Trustee to take any action under this Indenture, the Issuers or
such Subsidiary Guarantors shall furnish to the Trustee:

         (a) an Officers' Certificate in form and substance reasonably
satisfactory to the Trustee (which shall include the statements set forth in
Section 13.05 hereof) stating that, in the opinion of the signers, all
conditions precedent and covenants, if any, provided for in this Indenture
relating to the proposed action have been satisfied; and

         (b) an Opinion of Counsel in form and substance reasonably satisfactory
to the Trustee (which shall include the statements set forth in Section 13.05
hereof) stating that, in the opinion of such counsel, all such conditions
precedent and covenants have been satisfied.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more such Persons as to other matters, and any such Person may certify or
give an opinion as to such matters in one or several documents.

                                       108

<PAGE>

         Any certificate or opinion of an Officer of the General Partner, an
Issuer or any Subsidiary Guarantor may be based, insofar as it relates to legal
matters, upon a certificate or opinion of, or representations by, counsel,
unless such Officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the matters
upon which his certificate or opinion is based are erroneous. Any such
certificate or Opinion of Counsel may be based, and may state that it is so
based, insofar as it relates to factual matters, upon a certificate or opinion
of, or representations by, an Officer or Officers of the General Partner, an
Issuer or such Subsidiary Guarantor stating that the information with respect to
such factual matters is in possession of the General Partner, an Issuer or such
Subsidiary Guarantor, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate of opinion or representations
with respect to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 13.05. STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

         Each certificate or opinion with respect to compliance with a condition
or covenant provided for in this Indenture (other than a certificate provided
pursuant to TIA Section 314(a)(4)) shall comply with the provisions of TIA
Section 314(e) and shall include:

         (a) a statement that the Person making such certificate or opinion has
read such covenant or condition;

         (b) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such
certificate or opinion are based;

         (c) a statement that, in the opinion of such Person, he or she has made
such examination or investigation as is necessary to enable him or her to
express an informed opinion as to whether or not such covenant or condition has
been satisfied; and

         (d) a statement as to whether or not, in the opinion of such Person,
such condition or covenant has been satisfied.

Holders. The Registrar or Paying Agent may make reasonable rules and set
reasonable requirements for its functions.

SECTION 13.07. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, PARTNERS,
               EMPLOYEES, INCORPORATORS, STOCKHOLDERS AND MEMBERS.

         No past, present or future director, officer, partner, employee,
incorporator, stockholder or member of either of the Issuers, the General
Partner or any Subsidiary Guarantor, as such, shall have any liability for any
Obligations of either of the Issuers or any Subsidiary

                                       109

<PAGE>

Guarantor under the Notes, this Indenture or the Guarantees or for any claim
based on, in respect of, or by reason of, such Obligations or their creation.

or debt agreement of either of the Issuers or any Subsidiary of the Partnership
or of any other Person. Any such indenture, loan or debt agreement may not be
used to interpret this Indenture or the Guarantees.

impaired thereby.

SECTION 13.12. COUNTERPART ORIGINALS.

         The parties may sign any number of copies of this Indenture. Each

agreement.

         The Table of Contents, Cross-Reference Table and Headings of the
Articles and Sections of this Indenture have been inserted for convenience of
