     Section 2. Holders. A Person is deemed to be a holder of Transfer

          (a) Unless the Exchange Offer shall not be permitted by applicable
     federal law (after the procedures set forth in Section 6(a)(i) below have
     been complied with), the Issuers and the Subsidiary Guarantors shall (i)
     cause the Exchange Offer Registration Statement to be filed with the
     Commission as soon as practicable after the Closing Date, but in no event
     later than 95 days after the Closing Date (such 95th day being the "Filing
     Deadline"), (ii) use its best efforts to cause such Exchange Offer
     Registration Statement to become effective at the earliest possible time,
     but in no event later than 150 days after the Closing Date (such 150th day
     being the "Effectiveness Deadline"), (iii) in connection with the
     foregoing, (A) file all pre-effective amendments to such Exchange Offer
     Registration Statement as may be necessary in order to cause it to become
     effective, (B) file, if applicable, a post-effective amendment to such
     Exchange Offer Registration Statement pursuant to Rule 430A under the Act
     and (C) cause all necessary filings, if any, in connection with the
     registration and qualification of the Series B Notes to be made under the
     Blue Sky laws of such jurisdictions as are necessary to permit Consummation
     of the Exchange Offer, and (iv) upon the effectiveness of such Exchange
     Offer Registration Statement, commence and Consummate the Exchange Offer.
     The Exchange Offer shall be on the appropriate form permitting (i)
     registration of the Series B Notes to be offered in exchange for the Series
     A Notes that are Transfer Restricted Securities and (ii) resales of Series
     B Notes by Broker-Dealers that tendered into the Exchange Offer Series A
     Notes that such Broker-Dealer acquired for its own account as a result of
     market making activities or other trading activities (other than Series A
     Notes acquired directly from the Issuers or any of their Affiliates) as
     contemplated by Section 3(c) below.

                                       3

<PAGE>

          (b) The Issuers and the Subsidiary Guarantors shall use their
     respective best efforts to cause the Exchange Offer Registration Statement
     to be effective continuously, and shall keep the Exchange Offer open for a
     period of not less than the minimum period required under applicable
     federal and state securities laws to Consummate the Exchange Offer;
     provided, however, that in no event shall such period be less than 20
     Business Days. The Issuers and the Subsidiary Guarantors shall cause the
     Exchange Offer to comply with all applicable federal and state securities
     laws. No securities other than the Series B Notes shall be included in the
     Exchange Offer Registration Statement. The Issuers and the Subsidiary
     Guarantors shall use their respective best efforts to cause the Exchange
     Offer to be Consummated on the earliest practicable date after the Exchange
     Offer Registration Statement has become effective, but in no event later
     than 180 days after the Closing Date (such 180th day being the
     "Consummation Deadline").

          (c) The Issuers shall include a "Plan of Distribution" section in the
     Prospectus contained in the Exchange Offer Registration Statement and
     indicate therein that any Broker-Dealer who holds Transfer Restricted
     Securities that were acquired for the account of such Broker-Dealer as a
     result of market-making activities or other trading activities (other than
     Series A Notes acquired directly from the Issuers or any Affiliate of the
     Issuers) may exchange such Transfer Restricted Securities pursuant to the
     Exchange Offer. Such "Plan of Distribution" section shall also contain all
     other information with respect to such sales by such Broker-Dealers that
     the Commission may require in order to permit such sales pursuant thereto,
     but such "Plan of Distribution" shall not name any such Broker-Dealer or
     disclose the amount of Transfer Restricted Securities held by any such
     Broker-Dealer, except to the extent required by the Commission as a result
     of a change in policy, rules or regulations after the date of this
     Agreement.

     Because such Broker-Dealer may be deemed to be an "underwriter" within the
     meaning of the Act and must, therefore, deliver a prospectus meeting the
     requirements of the Act in connection with its initial sale of any Series B
     Notes received by such Broker-Dealer in the Exchange Offer, the Issuers and
     Subsidiary Guarantors shall permit the use of the Prospectus contained in
     the Exchange Offer Registration Statement by such Broker-Dealer to satisfy
     such prospectus delivery requirement. To the extent necessary to ensure
     that the prospectus contained in the Exchange Offer Registration Statement
     is available for sales of Series B Notes by such Broker-Dealers, the
     Issuers and the Subsidiary Guarantors agree to use their respective best
     efforts to keep the Exchange Offer Registration Statement continuously
     effective, supplemented, amended and current as required by and subject to
     the provisions of Sections 6(a) and (c) hereof and in conformity with the
     requirements of this Agreement, the Act and the policies, rules and
     regulations of the Commission as announced from time to time, for a period
     of one year from the Consummation Deadline or such shorter period as will
     terminate when all Transfer Restricted Securities covered by such
     Registration Statement have been sold pursuant thereto. The Issuers and the
     Subsidiary Guarantors shall provide sufficient copies of the latest version
     of such Prospectus to such Broker-Dealers, promptly upon request, and in no
     event later than one day after such request, at any time during such
     period.

                                       4

     Section 4. Shelf Registration.

          (a) Shelf Registration. If (i) the Exchange Offer is not permitted by
     applicable law (after the Issuers and the Subsidiary Guarantors have
     complied with the procedures set forth in Section 6(a)(i) below) or (ii) if
     any Holder of Transfer Restricted Securities shall notify the Issuers
     within 20 Business Days following the Consummation Deadline that (A) such
     Holder was prohibited by law or Commission policy from participating in the
     Exchange Offer or (B) such Holder may not resell the Series B Notes
     acquired by it in the Exchange Offer to the public without delivering a
     prospectus and the Prospectus contained in the Exchange Offer Registration
     Statement is not appropriate or available for such resales by such Holder
     or (C) such Holder is a Broker-Dealer and holds Series A Notes acquired
     directly from the Issuers or any of their Affiliates, then the Issuers and
     the Subsidiary Guarantors shall:

               (x) cause to be filed, on or prior to 30 days after the earlier
          of (i) the date on which the Issuers determine that the Exchange Offer
          Registration Statement cannot be filed as a result of clause (a)(i)
          above and (ii) the date on which the Issuers receive the notice
          specified in clause (a)(ii) above, (such earlier date, the "Filing
          Deadline"), a shelf registration statement pursuant to Rule 415 under
          the Act (which may be an amendment to the Exchange Offer Registration
          Statement (the "Shelf Registration Statement")), relating to all
          Transfer Restricted Securities, and

               (y) shall use their respective best efforts to cause such Shelf
          Registration Statement to become effective on or prior to 60 days
          after the Filing Deadline for the Shelf Registration Statement (such
          60th day the "Effectiveness Deadline").

     If, after the Issuers and the Subsidiary Guarantors have filed an Exchange
     Offer Registration Statement that satisfies the requirements of Section
     3(a) above, the Issuers are required to file and make effective a Shelf
     Registration Statement solely because the Exchange Offer is not permitted
     under applicable federal law (i.e., clause (a)(i) above), then the filing
     of the Exchange Offer Registration Statement shall be deemed to satisfy the
     requirements of clause (x) above; provided that, in such event, the Issuers
     and the Subsidiary Guarantors shall remain obligated to meet the
     Effectiveness Deadline set forth in clause (y).

     To the extent necessary to ensure that the Shelf Registration Statement is
     available for sales of Transfer Restricted Securities by the Holders
     thereof entitled to the benefit of this Section 4(a) and the other
     securities required to be registered therein pursuant to Section 6(b)(ii)
     hereof, the Issuers and the Subsidiary Guarantors shall use their
     respective best efforts to keep any Shelf Registration Statement required
     by this Section 4(a) continuously effective, supplemented, amended and
     current as required by and subject to the provisions of Sections 6(b) and
     (c) hereof and in conformity with the requirements of this Agreement, the
     Act and the policies, rules and regulations of the Commission as announced
     from time to time, for a period of at least two years (as extended pursuant
     to Section 6(d))

                                       5

<PAGE>

     following the Closing Date, or such shorter period as will terminate when
     all Transfer Restricted Securities covered by such Shelf Registration
     Statement have been sold pursuant thereto.

          (b) Provision by Holders of Certain Information in Connection with the
     Shelf Registration Statement. No Holder of Transfer Restricted Securities
     may include any of its Transfer Restricted Securities in any Shelf
     Registration Statement pursuant to this Agreement unless and until such
     Holder furnishes to the Issuers in writing, within 20 days after receipt of
     a request therefor, the information specified in Item 507 or 508 of
     Regulation S-K, as applicable, of the Act for use in connection with any
     Shelf Registration Statement or Prospectus (or preliminary Prospectus)
     included therein. No Holder of Transfer Restricted Securities shall be
     entitled to liquidated damages pursuant to Section 5 hereof unless and
     until such Holder shall have provided all such information. Each selling
     Holder agrees to promptly furnish additional information required to be
     disclosed in order to make the information previously furnished to the
     Issuers by such Holder not materially misleading.

     Section 5. Liquidated Damages. If (i) any Registration Statement required
by this Agreement is not filed with the Commission on or prior to the applicable
Filing Deadline, (ii) any such Registration Statement has not been declared
effective by the Commission on or prior to the applicable Effectiveness
Deadline, (iii) the Exchange Offer has not been Consummated on or prior to the
Consummation Deadline or (iv) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable for its intended purpose without being succeeded
within 2 days by a post-effective amendment to such Registration Statement that
cures such failure and that is itself declared effective within 2 days of filing
such post-effective amendment to such Registration Statement (each such event
referred to in clauses (i) through (iv), a "Registration Default"), then the
Issuers and the Subsidiary Guarantors hereby jointly and severally agree to pay
to each Holder of Transfer Restricted Securities affected thereby liquidated
damages in an amount equal to $.05 per week per $1,000 in principal amount of
Transfer Restricted Securities held by such Holder for each week or portion
thereof that the Registration Default continues for the first 90-day period
immediately following the occurrence of such Registration Default. The amount of
the liquidated damages shall increase by an additional $.05 per week per $1,000
in principal amount of Transfer Restricted Securities with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of liquidated damages of $.50 per week per $1,000 in principal
amount of Transfer Restricted Securities; provided that the Issuers and the
Subsidiary Guarantors shall in no event be required to pay liquidated damages
for more than one Registration Default at any given time. Notwithstanding
anything to the contrary set forth herein, (1) upon filing of the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of (i) above, (2) upon the effectiveness of the Exchange
Offer Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of (ii) above, (3) upon Consummation of the Exchange
Offer, in the case of (iii) above, or (4) upon the filing of a post-effective
amendment to the Registration Statement or an additional Registration Statement
that causes the Exchange Offer Registration Statement (and/or, if applicable,
the Shelf Registration Statement) to again be declared effective or made usable
in the case of (iv) above, the accrual of liquidated damages payable with
respect to the

                                       6

<PAGE>

Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or
(iv), as applicable, shall cease.

     All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner providing for the payment of interest in the Indenture,
on each Interest Payment Date, as more fully set forth in the Indenture and the
Notes; provided however, that any accrued liquidated damages that are unpaid at
the time any Notes cease to be Transfer Restricted Securities upon consummation
of the Exchange Offer shall be paid on or promptly after the date of such
consummation to the Holders of record of such Transfer Restricted Securities on
such date. Notwithstanding the fact that any securities for which liquidated
damages are due cease to be Transfer Restricted Securities, all obligations of
the Issuers and the Subsidiary Guarantors to pay liquidated damages with respect
to securities shall survive until such time as such obligations with respect to
such securities shall have been satisfied in full.

     Section 6. Registration Procedures.

          (a) Exchange Offer Registration Statement. In connection with the
     Exchange Offer, the Issuers and the Subsidiary Guarantors shall (x) comply
     with all applicable provisions of Section 6(c) below, (y) use their
     respective best efforts to effect such exchange and to permit the resale of
     Series B Notes by Broker-Dealers that tendered in the Exchange Offer Series
     A Notes that such Broker-Dealer acquired for its own account as a result of
     its market making activities or other trading activities (other than Series
     A Notes acquired directly from the Issuers or any of their Affiliates)
     being sold in accordance with the intended method or methods of
     distribution thereof, and (z) comply with all of the following provisions:

               (i) If, following the date hereof there has been announced a
          change in Commission policy with respect to exchange offers such as
          the Exchange Offer, that in the reasonable opinion of counsel to the
          Issuers raises a substantial question as to whether the Exchange Offer
          is permitted by applicable federal law, the Issuers and the Subsidiary
          Guarantors hereby agree to seek a no-action letter or other favorable
          decision from the Commission allowing the Issuers and the Subsidiary
          Guarantors to Consummate an Exchange Offer for such Transfer
          Restricted Securities. The Issuers and the Subsidiary Guarantors
          hereby agree to pursue the issuance of such a decision to the
          Commission staff level. In connection with the foregoing, the Issuers
          and the Subsidiary Guarantors hereby agree to take all such other
          actions as may be requested by the Commission or otherwise required in
          connection with the issuance of such decision, including without
          limitation (A) participating in telephonic conferences with the
          Commission, (B) delivering to the Commission staff an analysis
          prepared by counsel to the Issuers setting forth the legal bases, if
          any, upon which such counsel has concluded that such an Exchange Offer
          should be permitted and (C) diligently pursuing a resolution (which
          need not be favorable) by the Commission staff.

               (ii) As a condition to its participation in the Exchange Offer,
          each Holder of Transfer Restricted Securities (including, without
          limitation, any

                                       7

<PAGE>

          Holder who is a Broker Dealer) shall furnish, upon the request of the
          Issuers, prior to the Consummation of the Exchange Offer, a written
          representation to the Issuers and the Subsidiary Guarantors (which may
          be contained in the letter of transmittal contemplated by the Exchange
          Offer Registration Statement) to the effect that (A) it is not an
          Affiliate of the Issuers, (B) it is not engaged in, and does not
          intend to engage in, and has no arrangement or understanding with any
          Person to participate in, a distribution of the Series B Notes to be
          issued in the Exchange Offer, (C) it is acquiring the Series B Notes
          in its ordinary course of business and (D) if the undersigned is a
          Broker-Dealer, the Series A Notes being tendered constitute Series A
          Notes acquired as the result of market-making activities or other
          trading activities (other than Series A Notes acquired directly from
          the Issuers or any of their Affiliates). As a condition to its
          participation in the Exchange Offer, each Holder shall acknowledge and
          agree that (x) any person participating in Exchange Offer with the
          intention or for the purpose of distributing the Series B Notes, (1)
          could not, under Commission policy as in effect on the date of this
          Agreement, rely on the position of the Commission enunciated in Morgan
          Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital
          Holdings Corporation (available May 13, 1988), as interpreted in the
          Commission's letter to Shearman & Sterling dated July 2, 1993, and
          similar no-action letters (including, if applicable, any no-action
          letter obtained pursuant to clause (i) above), and (2) must comply
          with the registration and prospectus delivery requirements of the Act
          in connection with a secondary resale transaction and that such a
          secondary resale transaction must be covered by an effective
          registration statement containing the selling security holder
          information required by Item 507 or 508, as applicable, of Regulation
          S-K and (y) any Broker-Dealer that pursuant to the Exchange Offer
          receives Series B Notes for its own account in exchange for Series A
          Notes which it acquired for its own account as a result of
          market-making activities or other trading activities must deliver a
          prospectus meeting the requirements of the Securities Act in
          connection with any resale of such Series B Notes.

               (iii) Prior to effectiveness of the Exchange Offer Registration
          Statement, the Issuers and the Subsidiary Guarantors shall provide a
          supplemental letter to the Commission (A) stating that the Issuers and
          the Subsidiary Guarantors are registering the Exchange Offer in
          reliance on the position of the Commission enunciated in Exxon Capital
          Holdings Corporation (available May 13, 1988), Morgan Stanley and Co.,
          Inc. (available June 5, 1991) as interpreted in the Commission's
          letter to Shearman & Sterling dated July 2, 1993, and, if applicable,
          any no-action letter obtained pursuant to clause (i) above, (B)
          including a representation that neither the Issuers nor any Subsidiary
          Guarantor has entered into any arrangement or understanding with any
          Person to distribute the Series B Notes to be received in the Exchange
          Offer and that, to the best of the Issuers' and each Subsidiary
          Guarantor's information and belief, each Holder participating in the
          Exchange Offer is acquiring the Series B Notes in its ordinary course
          of business and has no arrangement or understanding with any Person to
          participate in the distribution of the Series B Notes received in the
          Exchange Offer and (C) any other undertaking or representation
          required by the

          Commission as set forth in any no-action letter obtained pursuant to
          clause (i) above, if applicable.

          (b) Shelf Registration Statement. In connection with the Shelf
     Registration Statement, the Issuers and the Subsidiary Guarantors shall:

               (i) comply with all the provisions of Section 6(c) below and use
          their respective best efforts to effect such registration to permit
          the sale of the Transfer Restricted Securities being sold in
          accordance with the intended method or methods of distribution thereof
          (as indicated in the information furnished to the Issuers pursuant to
          Section 4(b) hereof), and pursuant thereto the Issuers and the
          Subsidiary Guarantors will prepare and file with the Commission a
          Registration Statement relating to the registration on any appropriate
          form under the Act, which form shall be available for the sale of the
          Transfer Restricted Securities in accordance with the intended method
          or methods of distribution thereof within the time periods and
          otherwise in accordance with the provisions hereof.

               (ii) issue, upon the request of any Holder or purchaser of Series
          A Notes covered by any Shelf Registration Statement contemplated by
          this Agreement, Series B Notes having an aggregate principal amount
          equal to the aggregate principal amount of Series A Notes sold
          pursuant to the Shelf Registration Statement and surrendered to the
          Issuers for cancellation; the Issuers shall register Series B Notes on
          the Shelf Registration Statement for this purpose and issue the Series
          B Notes to the purchaser(s) of securities subject to the Shelf
          Registration Statement in the names as such purchaser(s) shall
          designate.

          (c) General Provisions. In connection with any Registration Statement
     and any related Prospectus required by this Agreement, the Issuers and the
     Subsidiary Guarantors shall:

               (i) use their respective best efforts to keep such Registration
          Statement continuously effective and provide all requisite financial
          statements for the period specified in Section 3 or 4 of this
          Agreement, as applicable. Upon the occurrence of any event that would
          cause any such Registration Statement or the Prospectus contained
          therein (A) to contain an untrue statement of material fact or omit to
          state any material fact necessary to make the statements therein not
          misleading or (B) not to be effective and usable for resale of
          Transfer Restricted Securities during the period required by this
          Agreement, the Issuers and the Subsidiary Guarantors shall file
          promptly an appropriate amendment to such Registration Statement
          curing such defect, and, if Commission review is required, use their
          respective best efforts to cause such amendment to be declared
          effective as soon as practicable;

               (ii) prepare and file with the Commission such amendments and
          post-effective amendments to the applicable Registration Statement as
          may be necessary to keep such Registration Statement effective for the
          applicable period set forth in Section 3 or 4 hereof, as the case may
          be; cause the Prospectus to be

                                       9

<PAGE>

          supplemented by any required Prospectus supplement, and as so
          supplemented to be filed pursuant to Rule 424 under the Act, and to
          comply fully with Rules 424, 430A and 462, as applicable, under the
          Act in a timely manner; and comply with the provisions of the Act with
          respect to the disposition of all securities covered by such
          Registration Statement during the applicable period in accordance with
          the intended method or methods of distribution by the sellers thereof
          set forth in such Registration Statement or supplement to the
          Prospectus;

               (iii) advise each Holder promptly and, if requested by such
          Holder, confirm such advice in writing, (A) when the Prospectus or any
          Prospectus supplement or post-effective amendment has been filed, and,
          with respect to any applicable Registration Statement or any
          post-effective amendment thereto, when the same has become effective,
          (B) of any request by the Commission for amendments to the
          Registration Statement or amendments or supplements to the Prospectus
          or for additional information relating thereto, (C) of the issuance by
          the Commission of any stop order suspending the effectiveness of the
          Registration Statement under the Act or of the suspension by any state
          securities commission of the qualification of the Transfer Restricted
          Securities for offering or sale in any jurisdiction, or the initiation
          of any proceeding for any of the preceding purposes, and (D) of the
          existence of any fact or the happening of any event that makes any
          statement of a material fact made in the Registration Statement, the
          Prospectus, any amendment or supplement thereto or any document
          incorporated by reference therein untrue, or that requires the making
          of any additions to or changes in the Registration Statement in order
          to make the statements therein not misleading, or that requires the
          making of any additions to or changes in the Prospectus in order to
          make the statements therein, in the light of the circumstances under
          which they were made, not misleading. If at any time the Commission
          shall issue any stop order suspending the effectiveness of the
          Registration Statement, or any state securities commission or other
          regulatory authority shall issue an order suspending the qualification
          or exemption from qualification of the Transfer Restricted Securities
          under state securities or Blue Sky laws, the Issuers and the
          Subsidiary Guarantors shall use their respective best efforts to
          obtain the withdrawal or lifting of such order at the earliest
          possible time;

               (iv) subject to Section 6(c)(i), if any fact or event
          contemplated by Section 6(c)(iii)(D) above shall exist or have
          occurred, prepare a supplement or post-effective amendment to the
          Registration Statement or related Prospectus or any document
          incorporated therein by reference or file any other required document
          so that, as thereafter delivered to the purchasers of Transfer
          Restricted Securities, the Prospectus will not contain an untrue
          statement of a material fact or omit to state any material fact
          necessary to make the statements therein, in the light of the
          circumstances under which they were made, not misleading;

               (v) furnish to each Holder in connection with such exchange or
          sale, if any, before filing with the Commission, copies of any
          Registration Statement or any Prospectus included therein or any
          amendments or supplements to any such Registration Statement or
          Prospectus (including all documents incorporated by

                                       10

<PAGE>

          reference after the initial filing of such Registration Statement),
          which documents will be subject to the review and comment of such
          Holders in connection with such sale, if any, for a period of at least
          five Business Days, and the Issuers will not file any such
          Registration Statement or Prospectus or any amendment or supplement to
          any such Registration Statement or Prospectus (including all such
          documents incorporated by reference) to which such Holders shall
          reasonably object within five Business Days after the receipt thereof.
          A Holder shall be deemed to have reasonably objected to such filing if
          such Registration Statement, amendment, Prospectus or supplement, as
          applicable, as proposed to be filed, contains an untrue statement of a
          material fact or omits to state any material fact necessary to make
          the statements therein not misleading or fails to comply with the
          applicable requirements of the Act;

               (vi) promptly provide, prior to the filing of any document that
          is to be incorporated by reference into a Registration Statement or
          Prospectus, copies of such document to each Holder in connection with
          such exchange or sale, if any, make the Issuers' and the Subsidiary
          Guarantors' representatives available for discussion of such document
          and other customary due diligence matters, and include such
          information in such document prior to the filing thereof as such
          Holders may reasonably request;

               (vii) make available, at reasonable times, for inspection by each
          Holder and any attorney or accountant retained by such Holders, all
          financial and other records, and pertinent corporate documents of the
          Issuers and the Subsidiary Guarantors and cause the Issuers' and the
          Subsidiary Guarantors' officers, directors and employees to supply all
          information reasonably requested by any such Holder, attorney or
          accountant in connection with such Registration Statement or any
          post-effective amendment thereto subsequent to the filing thereof and
          prior to its effectiveness;

               (viii) if requested by any Holders in connection with such
          exchange or sale, promptly include in any Registration Statement or
          Prospectus, pursuant to a supplement or post-effective amendment if
          necessary, such information as such Holders may reasonably request to
          have included therein, including, without limitation, information
          relating to the "Plan of Distribution" of the Transfer Restricted
          Securities; and make all required filings of such Prospectus
          supplement or post-effective amendment as soon as practicable after
          the Issuers are notified of the matters to be included in such
          Prospectus supplement or post-effective amendment;

               (ix) furnish to each Holder in connection with such exchange or
          sale, without charge, at least one copy of the Registration Statement,
          as first filed with the Commission, and of each amendment thereto,
          including all documents incorporated by reference therein and all
          exhibits (including exhibits incorporated therein by reference);

                                       11

<PAGE>

               (x) deliver to each Holder without charge, as many copies of the
          Prospectus (including each preliminary prospectus) and any amendment
          or supplement thereto as such Persons reasonably may request; the
          Issuers and the Subsidiary Guarantors hereby consent to the use (in
          accordance with law) of the Prospectus and any amendment or supplement
          thereto by each selling Holder in connection with the offering and the
          sale of the Transfer Restricted Securities covered by the Prospectus
          or any amendment or supplement thereto;

               (xi) upon the request of any Holder, enter into such agreements
          (including underwriting agreements) and make such representations and
          warranties and take all such other actions in connection therewith in
          order to expedite or facilitate the disposition of the Transfer
          Restricted Securities pursuant to any applicable Registration
          Statement contemplated by this Agreement as may be reasonably
          requested by any Holder in connection with any sale or resale pursuant
          to any applicable Registration Statement. In such connection, the
          Issuers and the Subsidiary Guarantors shall:

                    (A) upon request of any Holder, furnish (or in the case of
               paragraphs (2) and (3), use their best efforts to cause to be
               furnished) to each Holder, upon Consummation of the Exchange
               Offer or upon the effectiveness of the Shelf Registration
               Statement, as the case may be:

                         (1) a certificate, dated such date, signed on behalf of
                    the Issuers and each Subsidiary Guarantor by (x) the
                    President or any Vice President and (y) a principal
                    financial or accounting officer of each of the Issuers and
                    each Subsidiary Guarantor, confirming, as of the date
                    thereof, the matters set forth in Sections 6(aa), 9(a) and
                    9(b) of the Purchase Agreement and such other similar
                    matters as such Holders may reasonably request;

                         (2) an opinion, dated the date of Consummation of the
                    Exchange Offer or the date of effectiveness of the Shelf
                    Registration Statement, as the case may be, of counsel for
                    the Issuers and the Subsidiary Guarantors covering matters
                    similar to those set forth in paragraph (e) of Section 9 of
                    the Purchase Agreement and such other matters as such Holder
                    may reasonably request, and in any event including a
                    statement to the effect that such counsel has participated
                    in conferences with officers and other representatives of
                    the Issuers and the Subsidiary Guarantors, and
                    representatives of the independent public accountants for
                    the Issuers and the Subsidiary Guarantors and have
                    considered the matters required to be stated therein and the
                    statements contained therein, although such counsel has not
                    independently verified the accuracy, completeness or
                    fairness of such statements; and that such counsel advises
                    that, on the basis of the foregoing, no facts came to such
                    counsel's attention that caused such counsel to believe that
                    the applicable Registration Statement, at the time such

                                       12

<PAGE>

                    Registration Statement or any post-effective amendment
                    thereto became effective and, in the case of the Exchange
                    Offer Registration Statement, as of the date of Consummation
                    of the Exchange Offer, contained an untrue statement of a
                    material fact or omitted to state a material fact required
                    to be stated therein or necessary to make the statements
                    therein not misleading, or that the Prospectus contained in
                    such Registration Statement as of its date and, in the case
                    of the opinion dated the date of Consummation of the
                    Exchange Offer, as of the date of Consummation, contained an
                    untrue statement of a material fact or omitted to state a
                    material fact required to be stated therein or necessary in
                    order to make the statements therein, in the light of the
                    circumstances under which they were made, not misleading.
                    Without limiting the foregoing, such counsel may state
                    further that such counsel assumes no responsibility for, and
                    has not independently verified, the accuracy, completeness
                    or fairness of the financial statements, notes and schedules
                    and other financial data included in any Registration
                    Statement contemplated by this Agreement or the related
                    Prospectus; and

                         (3) a customary comfort letter, dated the date of
                    Consummation of the Exchange Offer, or as of the date of
                    effectiveness of the Shelf Registration Statement, as the
                    case may be, from the Issuers' independent accountants, in
                    the customary form and covering matters of the type
                    customarily covered in comfort letters to underwriters in
                    connection with underwritten offerings, and affirming the
                    matters set forth in the comfort letters delivered pursuant
                    to Section 9(g) of the Purchase Agreement; and

                    (B) deliver such other documents and certificates as may be
               reasonably requested by the selling Holders to evidence
               compliance with the matters covered in clause (A) above and with
               any customary conditions contained in any agreement entered into
               by the Issuers and the Subsidiary Guarantors pursuant to this
               clause (xi);

                                       13

<PAGE>

               (xii) prior to any public offering of Transfer Restricted
          Securities, cooperate with the selling Holders and their counsel in
          connection with the registration and qualification of the Transfer
          Restricted Securities under the securities or Blue Sky laws of such
          jurisdictions as the selling Holders may request and do any and all
          other acts or things necessary or advisable to enable the disposition
          in such jurisdictions of the Transfer Restricted Securities covered by
          the applicable Registration Statement; provided, however, that neither
          the Issuers nor any Subsidiary Guarantor shall be required to register
          or qualify as a foreign corporation where it is not now so qualified
          or to take any action that would subject it to the service of process
          in suits or to taxation, other than as to matters and transactions
          relating to the Registration Statement, in any jurisdiction where it
          is not now so subject;

               (xiii) in connection with any sale of Transfer Restricted
          Securities that will result in such securities no longer being
          Transfer Restricted Securities, cooperate with the Holders to
          facilitate the timely preparation and delivery of certificates
          representing Transfer Restricted Securities to be sold and not bearing
          any restrictive legends; and to register such Transfer Restricted
          Securities in such denominations and such names as the selling Holders
          may request at least two Business Days prior to such sale of Transfer
          Restricted Securities;

               (xiv) use their respective best efforts to cause the disposition
          of the Transfer Restricted Securities covered by the Registration
          Statement to be registered with or approved by such other governmental
          agencies or authorities as may be necessary to enable the seller or
          sellers thereof to consummate the disposition of such Transfer
          Restricted Securities, subject to the proviso contained in clause
          (xii) above;

               (xv) provide a CUSIP number for all Transfer Restricted
          Securities not later than the effective date of a Registration
          Statement covering such Transfer Restricted Securities and provide the
          Trustee under the Indenture with printed certificates for the Transfer
          Restricted Securities which are in a form eligible for deposit with
          The Depository Trust Company;

               (xvi) otherwise use their respective best efforts to comply with
          all applicable rules and regulations of the Commission, and make
          generally available to their security holders with regard to any
          applicable Registration Statement, as soon as practicable, a
          consolidated earnings statement meeting the requirements of Rule 158
          (which need not be audited) covering a twelve-month period beginning
          after the effective date of the Registration Statement (as such term
          is defined in paragraph (c) of Rule 158 under the Act);

               (xvii) cause the Indenture to be qualified under the TIA not
          later than the effective date of the first Registration Statement
          required by this Agreement and, in connection therewith, cooperate
          with the Trustee and the Holders to effect such changes to the
          Indenture as may be required for such Indenture to be so qualified in
          accordance with the terms of the TIA; and execute and use its best
          efforts to

                                       14

<PAGE>

          cause the Trustee to execute, all documents that may be required to
          effect such changes and all other forms and documents required to be
          filed with the Commission to enable such Indenture to be so qualified
          in a timely manner; and

               (xviii) provide promptly to each Holder, upon request, each
          document filed with the Commission pursuant to the requirements of
          Section 13 or Section 15(d) of the Exchange Act.

          (d) Restrictions on Holders. Each Holder agrees by acquisition of a
     Transfer Restricted Security that, upon receipt of the notice referred to
     in Section 6(c)(iii)(C) or any notice from the Issuers of the existence of
     any fact of the kind described in Section 6(c)(iii)(D) hereof (in each
     case, a "Suspension Notice"), such Holder will forthwith discontinue
     disposition of Transfer Restricted Securities pursuant to the applicable
     Registration Statement until (i) such Holder has received copies of the
     supplemented or amended Prospectus contemplated by Section 6(c)(iv) hereof,
     or (ii) such Holder is advised in writing by the Issuers that the use of
     the Prospectus may be resumed, and has received copies of any additional or
     supplemental filings that are incorporated by reference in the Prospectus
     (in each case, the "Recommencement Date"). Each Holder receiving a
     Suspension Notice hereby agrees that it will either (i) destroy any
     Prospectuses, other than permanent file copies, then in such Holder's
     possession which have been replaced by the Issuers with more recently dated
     Prospectuses or (ii) deliver to the Issuers (at the Issuers' expense) all
     copies, other than permanent file copies, then in such Holder's possession
     of the Prospectus covering such Transfer Restricted Securities that was
     current at the time of receipt of the Suspension Notice. The time period
     regarding the effectiveness of such Registration Statement set forth in
     Section 3 or 4 hereof, as applicable, shall be extended by a number of days
     equal to the number of days in the period from and including the date of
     delivery of the Suspension Notice to the date of delivery of the
     Recommencement Date.

          (e) Effectiveness of Registration Statement. Notwithstanding anything
     to the contrary contained in this Agreement, the obligation of the Issuers
     and the Subsidiary Guarantors hereunder to maintain the effectiveness of
     any Registration Statement and any related Prospectus may be suspended,
     without default or penalty to the Issuers or the Subsidiary Guarantors, for
     one or more periods of time as may be required with respect to such
     Registration Statement if (A) the Board of Directors of the General Partner
     shall have determined that the offering and sales under the Registration
     Statement, the filing of such Registration Statement or the maintenance of
     its effectiveness would require disclosure of or would interfere in any
     material respect with any material financing, acquisition, merger, offering
     or other transaction involving the Issuers or the Subsidiary Guarantors or
     would otherwise require disclosure of nonpublic information that could
     materially and adversely affect the Issuers or the Subsidiary Guarantors or
     (B) the Issuers are required by any state or federal securities laws to
     file an amendment or supplement to such Registration Statement for the
     purpose of incorporating quarterly or annual information, which is not
     automatically effective. Further, the Issuers and the Subsidiary Guarantors
     shall be deemed to have used their respective best efforts to keep any
     Registration Statement continuously effective if either (A) or (B) above
     has occurred.

     Section 7. Registration Expenses.

          (a) All expenses incident to the Issuers' and the Subsidiary
     Guarantors' performance of or compliance with this Agreement will be borne
     by the Issuers, regardless of whether a Registration Statement becomes
     effective, including without limitation: (i) all registration and filing
     fees and expenses; (ii) all fees and expenses of compliance with federal
     securities and state Blue Sky or securities laws; (iii) all expenses of
     printing (including printing certificates for the Series B Notes to be
     issued in the Exchange Offer and printing of Prospectuses), messenger and
     delivery services and telephone; (iv) all fees and disbursements of counsel
     for the Issuers, the Subsidiary Guarantors and the Holders of Transfer
     Restricted Securities; (v) all application and filing fees in connection
     with listing the Series B Notes on a national securities exchange or
     automated quotation system pursuant to the requirements hereof; and (vi)
     all fees and disbursements of independent certified public accountants of
     the Issuers and the Subsidiary Guarantors (including the expenses of any
     special audit and comfort letters required by or incident to such
     performance).

          The Issuers will, in any event, bear their and the Subsidiary
     Guarantors' internal expenses (including, without limitation, all salaries
     and expenses of its officers and employees performing legal or accounting
     duties), the expenses of any annual audit and the fees and expenses of any
     Person, including special experts, retained by the Issuers or the
     Subsidiary Guarantors.

          (b) In connection with any Registration Statement required by this
     Agreement (including, without limitation, the Exchange Offer Registration
     Statement and the Shelf Registration Statement), the Issuers and the
     Subsidiary Guarantors will reimburse the Initial Purchasers and the Holders
     of Transfer Restricted Securities who are tendering Series A Notes in the
     Exchange Offer and/or selling or reselling Series A Notes or Series B Notes
     pursuant to the "Plan of Distribution" contained in the Exchange Offer
     Registration Statement or the Shelf Registration Statement, as applicable,
     for the reasonable fees and disbursements of not more than one counsel, who
     shall be Simpson Thacher & Bartlett, unless another firm shall be chosen by
     the Holders of a majority in principal amount of the Transfer Restricted
     Securities for whose benefit such Registration Statement is being prepared.

     Section 8. Indemnification.

          (a) The Issuers and the Subsidiary Guarantors agree, jointly and
     severally, to indemnify and hold harmless each Holder, its directors,
     officers and each Person, if any, who controls such Holder (within the
     meaning of Section 15 of the Act or Section 20 of the Exchange Act), from
     and against any and all losses, claims, damages, liabilities or judgments
     (including without limitation, any legal or other expenses incurred in
     connection with investigating or defending any matter, including any action
     that could give rise to any such losses, claims, damages, liabilities or
     judgments) caused by any untrue statement or alleged untrue statement of a
     material fact contained in any Registration Statement, preliminary
     prospectus or Prospectus (or any amendment or supplement thereto) provided
     by the Issuers to any Holder or any prospective purchaser

                                       16

<PAGE>

     of Series B Notes or registered Series A Notes, or caused by any omission
     or alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, except
     insofar as such losses, claims, damages, liabilities or judgments are
     caused by an untrue statement or omission or alleged untrue statement or
     omission that is based upon information relating to any of the Holders
     furnished in writing to the Issuers by any of the Holders.

          (b) Each Holder of Transfer Restricted Securities agrees, severally
     and not jointly, to indemnify and hold harmless the Issuers and the
     Subsidiary Guarantors, and their respective directors and officers, and
     each Person, if any, who controls (within the meaning of Section 15 of the
     Act or Section 20 of the Exchange Act) the Issuers or the Subsidiary
     Guarantors, to the same extent as the foregoing indemnity from the Issuers
     and the Subsidiary Guarantors set forth in Section 8(a) above, but only
     with reference to information relating to such Holder furnished in writing
     to the Issuers by such Holder expressly for use in any Registration
     Statement. In no event shall any Holder, its directors, officers or any
     Person who controls such Holder be liable or responsible for any amount in
     excess of the amount by which the total amount received by such Holder with
     respect to its sale of Transfer Restricted Securities pursuant to a
     Registration Statement exceeds (i) the amount paid by such Holder for such
     Transfer Restricted Securities and (ii) the amount of any damages that such
     Holder, its directors, officers or any Person who controls such Holder has
     otherwise been required to pay by reason of such untrue or alleged untrue
     statement or omission or alleged omission.

          (c) In case any action shall be commenced involving any Person in
     respect of which indemnity may be sought pursuant to Section 8(a) or 8(b)
     (the "indemnified party"), the indemnified party shall promptly notify the
     Person against whom such indemnity may be sought (the "indemnifying
     person") in writing and the indemnifying party shall assume the defense of
     such action, including the employment of counsel reasonably satisfactory to
     the indemnified party and the payment of all fees and expenses of such
     counsel, as incurred (except that in the case of any action in respect of
     which indemnity may be sought pursuant to both Sections 8(a) and 8(b), a
     Holder shall not be required to assume the defense of such action pursuant
     to this Section 8(c), but may employ separate counsel and participate in
     the defense thereof, but the fees and expenses of such counsel, except as
     provided below, shall be at the expense of the Holder). Any indemnified
     party shall have the right to employ separate counsel in any such action
     and participate in the defense thereof, but the fees and expenses of such
     counsel shall be at the expense of the indemnified party unless (i) the
     employment of such counsel shall have been specifically authorized in
     writing by the indemnifying party, (ii) the indemnifying party shall have
     failed to assume the defense of such action or employ counsel reasonably
     satisfactory to the indemnified party or (iii) the named parties to any
     such action (including any impleaded parties) include both the indemnified
     party and the indemnifying party, and the indemnified party shall have been
     advised by such counsel that there may be one or more legal defenses
     available to it which are different from or additional to those available
     to the indemnifying party (in which case the indemnifying party shall not
     have the right to assume the defense of such action on behalf of the
     indemnified party). In any such case, the indemnifying party shall not, in
     connection with any one action or separate but substantially similar or
     related actions in the same

                                       17

<PAGE>

     jurisdiction arising out of the same general allegations or circumstances,
     be liable for the fees and expenses of more than one separate firm of
     attorneys (in addition to any local counsel) for all indemnified parties
     and all such fees and expenses shall be reimbursed as they are incurred.
     Such firm shall be designated in writing by a majority of the Holders, in
     the case of the parties indemnified pursuant to Section 8(a), and by the
     Issuers and Subsidiary Guarantors, in the case of parties indemnified
     pursuant to Section 8(b). The indemnifying party shall indemnify and hold
     harmless the indemnified party from and against any and all losses, claims,
     damages, liabilities and judgments by reason of any settlement of any
     action (i) effected with its written consent or (ii) effected without its
     written consent if the settlement is entered into more than twenty Business
     Days after the indemnifying party shall have received a request from the
     indemnified party for reimbursement for the fees and expenses of counsel
     (in any case where such fees and expenses are at the expense of the
     indemnifying party) and, prior to the date of such settlement, the
     indemnifying party shall have failed to comply with such reimbursement
     request. No indemnifying party shall, without the prior written consent of
     the indemnified party, effect any settlement or compromise of, or consent
     to the entry of judgment with respect to, any pending or threatened action
     in respect of which the indemnified party is or could have been a party and
     indemnity or contribution may be or could have been sought hereunder by the
     indemnified party, unless such settlement, compromise or judgment (i)
     includes an unconditional release of the indemnified party from all
     liability on claims that are or could have been the subject matter of such
     action and (ii) does not include a statement as to or an admission of
     fault, culpability or a failure to act, by or on behalf of the indemnified
     party.

          (d) To the extent that the indemnification provided for in this
     Section 8 is unavailable to an indemnified party in respect of any losses,
     claims, damages, liabilities or judgments referred to therein, then each
     indemnifying party, in lieu of indemnifying such indemnified party, shall
     contribute to the amount paid or payable by such indemnified party as a
     result of such losses, claims, damages, liabilities or judgments (i) in
     such proportion as is appropriate to reflect the relative benefits received
     by the Issuers and the Subsidiary Guarantors, on the one hand, and the
     Holders, on the other hand, from their sale of Transfer Restricted
     Securities or (ii) if the allocation provided by clause 8(d)(i) is not
     permitted by applicable law, in such proportion as is appropriate to
     reflect not only the relative benefits referred to in clause 8(d)(i) above
     but also the relative fault of the Issuers and the Subsidiary Guarantors,
     on the one hand, and of the Holder, on the other hand, in connection with
     the statements or omissions which resulted in such losses, claims, damages,
     liabilities or judgments, as well as any other relevant equitable
     considerations. The relative fault of the Issuers and the Subsidiary
     Guarantors, on the one hand, and of the Holder, on the other hand, shall be
     determined by reference to, among other things, whether the untrue or
     alleged untrue statement of a material fact or the omission or alleged
     omission to state a material fact relates to information supplied by the
     Issuers or such Subsidiary Guarantor, on the one hand, or by the Holder, on
     the other hand, and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission.

          The Issuers, the Subsidiary Guarantors and each Holder agree that it
     would not be just and equitable if contribution pursuant to this Section
     8(d) were determined by pro

                                       18

<PAGE>

     rata allocation (even if the Holders were treated as one entity for such
     purpose) or by any other method of allocation which does not take account
     of the equitable considerations referred to in the immediately preceding
     paragraph. The amount paid or payable by an indemnified party as a result
     of the losses, claims, damages, liabilities or judgments referred to in the
     immediately preceding paragraph shall be deemed to include, subject to the
     limitations set forth above, any legal or other expenses incurred by such
     indemnified party in connection with investigating or defending any matter,
     including any action that could have given rise to such losses, claims,
     damages, liabilities or judgments. Notwithstanding the provisions of this
     Section 8, no Holder, its directors, its officers or any Person, if any,
     who controls such Holder shall be required to contribute, in the aggregate,
     any amount in excess of the amount by which the total received by such
     Holder with respect to the sale of Transfer Restricted Securities pursuant
     to a Registration Statement exceeds (i) the amount paid by such Holder for
     such Transfer Restricted Securities and (ii) the amount of any damages
     which such Holder has otherwise been required to pay by reason of such
     untrue or alleged untrue statement or omission or alleged omission. No
     Person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Act) shall be entitled to contribution from any Person
     who was not guilty of such fraudulent misrepresentation. The Holders'
     obligations to contribute pursuant to this Section 8(d) are several in
     proportion to the respective principal amount of Transfer Restricted
     Securities held by each Holder hereunder and not joint.

     Section 9. Rule 144A and Rule 144. The Issuers and each Subsidiary
Guarantor agree with each Holder, for so long as any Transfer Restricted
Securities remain outstanding and during any period in which the Issuers or such
Subsidiary Guarantor (i) is not subject to Section 13 or 15(d) of the Exchange
Act, to make available, upon request of any Holder, to such Holder or beneficial
owner of Transfer Restricted Securities in connection with any sale thereof and
any prospective purchaser of such Transfer Restricted Securities designated by
such Holder or beneficial owner, the information required by Rule 144A(d)(4)
under the Act in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

     Section 10. Miscellaneous.

          (a) Remedies. The Issuers and the Subsidiary Guarantors acknowledge
     and agree that any failure by the Issuers and/or the Subsidiary Guarantors
     to comply with their respective obligations under Sections 3 and 4 hereof
     may result in material irreparable injury to the Initial Purchasers or the
     Holders for which there is no adequate remedy at law, that it will not be
     possible to measure damages for such injuries precisely and that, in the
     event of any such failure, the Initial Purchasers or any Holder may obtain
     such relief as may be required to specifically enforce the Issuers' and the
     Subsidiary Guarantors' obligations under Sections 3 and 4 hereof. The
     Issuers and the Subsidiary Guarantors further agree to waive the defense in
     any action for specific performance that a remedy at law would be adequate.

          (b) No Inconsistent Agreements. Neither the Issuers nor any Subsidiary
     Guarantor will, on or after the date of this Agreement, enter into any
     agreement with

                                       19

<PAGE>

     respect to its securities that is inconsistent with the rights granted to
     the Holders in this Agreement or otherwise conflicts with the provisions
     hereof. Neither the Issuers nor any Subsidiary Guarantor have previously
     entered into any agreement granting any registration rights with respect to
     its securities to any Person other than the registration rights (i) of El
     Paso Energy Partners Company and its affiliates in Section 6.14 of the
     Partnership Agreement, (ii) of EPEC Deepwater Gathering Company ("EPEC")
     and its successors pursuant to a registration rights agreement between EPEC
     and the Partnership which was executed in connection with the acquisition
     by the Partnership of an additional interest in Viosca Knoll Gathering
     Company, (iii) of Crystal Gas Storage, Inc. ("Crystal") pursuant to the
     registration rights agreement dated as of August 28, 2000 between Crystal
     and the Partnership which was executed in connection with the acquisition
     by the Partnership of the Crystal storage facilities, (iv) granted under
     the Partnership Credit Facility (as amended, restated and otherwise
     supplemented through the date hereof) and related agreements, (v) of the
     General Partner and its affiliates in Section 6.14 of the Partnership
     Agreement and in the registration rights agreement executed in connection
     with the November 2002 acquisition by the Partnership of the San Juan
     assets and (vi) granted pursuant to this Agreement. The rights granted to
     the Holders hereunder do not in any way conflict with and are not
     inconsistent with the rights granted to the holders of the Issuers' and the
     Subsidiary Guarantors' securities under any agreement in effect on the date
     hereof.

          (c) Amendments and Waivers. The provisions of this Agreement may not
     be amended, modified or supplemented, and waivers or consents to or
     departures from the provisions hereof may not be given unless (i) in the
     case of Section 5 hereof and this Section 10(c)(i), the Issuers have
     obtained the written consent of Holders of all outstanding Transfer
     Restricted Securities and (ii) in the case of all other provisions hereof,
     the Issuers have obtained the written consent of Holders of a majority of
     the outstanding principal amount of Transfer Restricted Securities
     (excluding Transfer Restricted Securities held by the Issuers or their
     Affiliates). Notwithstanding the foregoing, a waiver or consent to
     departure from the provisions hereof that relates exclusively to the rights
     of Holders whose Transfer Restricted Securities are being tendered pursuant
     to the Exchange Offer, and that does not affect directly or indirectly the
     rights of other Holders whose Transfer Restricted Securities are not being
     tendered pursuant to such Exchange Offer, may be given by the Holders of a
     majority of the outstanding principal amount of Transfer Restricted
     Securities subject to such Exchange Offer.

          (d) Third Party Beneficiary. The Holders shall be third party
     beneficiaries to the agreements made hereunder between the Issuers and the
     Subsidiary Guarantors, on the one hand, and the Initial Purchasers, on the
     other hand, and shall have the right to enforce such agreements directly to
     the extent they may deem such enforcement necessary or advisable to protect
     its rights or the rights of Holders hereunder.

          (e) Notices. All notices and other communications provided for or
     permitted hereunder shall be made in writing by hand-delivery, first-class
     mail (registered or certified, return receipt requested), telex,
     telecopier, or air courier guaranteeing overnight delivery:

          benefit of and be binding upon the successors and assigns of each of
          the parties, including without limitation and without the need for an
          express assignment, subsequent Holders; provided, that nothing herein

          disposition of Transfer Restricted Securities in violation of the
          terms hereof or of the Purchase Agreement or the Indenture. If any
          transferee of any Holder shall acquire Transfer Restricted Securities
          in any manner, whether by operation of law or otherwise, such Transfer
          Restricted Securities shall be held subject to all of the terms of
          this Agreement, and by taking and holding such Transfer Restricted
          Securities such Person shall be conclusively deemed to have agreed to
          be bound by and to perform all of the terms and provisions of this
          Agreement, including the restrictions on resale set forth in this
          Agreement and, if applicable, the Purchase Agreement, and such Person
          shall be entitled to receive the benefits hereof.

          counterparts and by the parties hereto in separate counterparts, each
          of which when so executed shall be deemed to be an original and all of
          which taken together shall constitute one and the same agreement.

               (h) Headings. The headings in this Agreement are for convenience
          of reference only and shall not limit or otherwise affect the meaning
          hereof.

               (i) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND
          CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

               (j) Severability. In the event that any one or more of the
          provisions contained herein, or the application thereof in any
          circumstance, is held invalid, illegal or unenforceable, the validity,
          legality and enforceability of any such provision in every other
          respect and of the remaining provisions contained herein shall not be
          affected or impaired thereby.

               (k) Entire Agreement. This Agreement is intended by the parties

SECTION 2.01. FORM AND DATING.

     The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto. The notation on each Note
relating to the Guarantees shall be substantially in the form set forth on
Exhibit D, which is a part of this Indenture. The Notes may have notations,
legends or endorsements required by law, stock exchange rule or usage. Each Note
shall be dated the date of its authentication. The Notes shall be in
denominations of $1,000 and integral multiples thereof.

     The terms and provisions contained in the Notes (including the Guarantees)
shall constitute, and are hereby expressly made, a part of this Indenture and
the Partnership, El Paso Finance, the Subsidiary Guarantors, and the Trustee, by
their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby. However, to the extent any provision of
any Note conflicts with the express provisions of this Indenture, the provisions
of this Indenture shall govern and be controlling.

     Notes issued in global form shall be substantially in the form of Exhibit A
attached hereto (including the Global Note Legend and the "Schedule of Exchanges
in the Global Note" attached thereto). Notes issued in definitive form shall be
substantially in the form of Exhibit A attached hereto (but without the Global

therein and each shall provide that it shall represent the aggregate principal
amount of outstanding Notes from time to time endorsed thereon and that the
aggregate principal amount of outstanding Notes represented thereby may from
time to time be reduced or increased, as appropriate, to reflect exchanges and

increase or decrease in the aggregate principal amount of outstanding Notes
represented thereby shall be made by the Trustee or the Note Custodian, at the
direction of the Trustee, in accordance with instructions given by the Holder
thereof as required by Section 2.06 hereof.

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

     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.

                                       30

<PAGE>

     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) $300,000,000 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

maintain an office or agency where Notes may be presented for registration 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 Partnership, El
Paso Finance or any of the Subsidiary Guarantors may act as Paying Agent or
Registrar.

     The Issuers initially appoint The Depository Trust Company ("DTC") to 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

                                       31

<PAGE>

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).

     (a) Transfer and Exchange of Global Notes. A Global Note may not be
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 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

<PAGE>

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

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 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

                                       33

<PAGE>

     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 of a beneficial interest in the Regulation S
          Global Note, then the transferor must deliver a certificate in the
          form of Exhibit B hereto, including the certifications in item (2)
          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.

          (iv) Transfer and Exchange of Beneficial Interests in a Restricted
     Global Note for Beneficial Interests in the Unrestricted Global Note. A
     beneficial interest in any Restricted Global Note may be exchanged by any
     holder thereof for a beneficial interest in an Unrestricted Global Note or
     transferred to a Person who takes delivery thereof in the form of a
     beneficial interest in an Unrestricted Global Note if the exchange or
     transfer complies with the requirements of clause (ii) above and:

               (A) such exchange or transfer is effected pursuant to the
          Exchange Offer in accordance with the Registration Rights Agreement
          and the holder of the beneficial interest to be transferred, in the
          case of an exchange, or the transferee, in the case of a transfer, is
          not (i) a broker-dealer, (ii) a Person participating in the

     (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Certificated Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Certificated
Notes, the principal amount of Notes represented by such Global Note shall be
reduced accordingly and an endorsement shall be made on such Global Note, by the
Trustee or by the Depositary at the direction of the Trustee, to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note, such other Global Note shall be increased accordingly
and an endorsement shall be made on such Global Note, by the Trustee or by the
Depositary at the direction of the Trustee, to reflect such increase.

     (i) General Provisions Relating to Transfers and Exchanges.

          (i) To permit registrations of transfers and exchanges, the Issuers
     shall execute and the Trustee shall authenticate Global Notes and

     Guarantees duly endorsed by the Subsidiary Guarantors) upon the Issuers'
     order or at the Registrar's request.

          (ii) No service charge shall be made to a holder of a beneficial
     interest in a Global Note or to a Holder of a Certificated Note for any
     registration of transfer or exchange, but the Issuers may require payment
     of a sum sufficient to cover any transfer tax or similar governmental
     charge payable in connection therewith (other than any such transfer taxes
     or similar governmental charge payable upon exchange or transfer pursuant
     to Sections 2.10, 3.06, 3.09, 4.06 and 9.05 hereof).

          (iii) The Registrar shall not be required to register the transfer of
     or exchange any Note selected for redemption in whole or in part, except
     the unredeemed portion of any Note being redeemed in part.

          (iv) All Global Notes and Certificated Notes (in each case,
     accompanied by a notation of the Guarantees duly endorsed by the Subsidiary
     Guarantors) issued upon any registration of transfer or exchange of Global
     Notes or Certificated Notes shall be the valid obligations of the Issuers
     and the Subsidiary Guarantors, evidencing the same debt, and entitled to
     the same benefits under this Indenture, as the Global Notes or Certificated
     Notes surrendered upon such registration of transfer or exchange.

          (v) The Issuers shall not be required (A) to issue, to register the
     transfer of or to exchange Notes during a period beginning at the opening
     of business 15 days before the day of mailing of notice of redemption and
     ending at the close of business on the day of such mailing, (B) to register
     the transfer of or to exchange any Note so selected for redemption in whole
     or in part, except the

                                       45

<PAGE>

     unredeemed portion of any Note being redeemed in part or (C) to register
     the transfer of or to exchange a Note between a record date and the next
     succeeding Interest Payment Date.

          (vi) Prior to due presentment for the registration of a transfer of
     any Note, the Trustee, any Agent and the Issuers may deem and treat the
     Person in whose name any Note is registered as the absolute owner of such
     Note for the purpose of receiving payment of principal of and interest on
     such Notes and for all other purposes, and none of the Trustee, any Agent
     or the Issuers shall be affected by notice to the 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

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

     (k) The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Note (including any transfers between or among beneficial owners of
interest in any Global Note) other than to require delivery of such certificate
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
(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.

                                       46

<PAGE>

     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 2.10. 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 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

                                       47

<PAGE>

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.

                            REDEMPTION AND PREPAYMENT

SECTION 3.01. NOTICES TO TRUSTEE.

     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

                                       48

<PAGE>

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:

          (a) if the Notes are listed for trading on a national 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
redemption to each Holder whose Notes are to be redeemed at its registered
address.

     The notice shall identify the Notes to be redeemed (including CUSIP
numbers) and shall state:

     (a) the redemption date;

     (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;

                                       49

<PAGE>

     (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
Issuers shall deposit with the Trustee or with the Paying Agent money sufficient
to pay the redemption price of and accrued interest and Liquidated Damages, if
applicable, on all Notes to be redeemed on that date. The Trustee or 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.

     If the Issuers comply with the provisions of the preceding paragraph, on
and after the redemption date, interest and Liquidated Damages, if 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 record date but on or
prior to the related Interest Payment Date, then any 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.

                                       50

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.

Partnership, El Paso Finance or any Restricted Subsidiary of the Partnership);
and (ii) the redemption must occur within 90 days of the date of the closing of
such Equity Offering.

     (c) Any redemption pursuant to this Section 3.07 shall be made pursuant to
the provisions of Section 3.01 through 3.06 hereof.

SECTION 3.08. MANDATORY REDEMPTION.

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

                                       51

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;

     (e) that Holders electing to have a Note purchased pursuant to any 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
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
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

                                       52

<PAGE>

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 or as soon as
practicable after the Purchase Date.

     Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

     The Issuers shall maintain in the Borough of Manhattan, The City of New

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
agency. If at any time the Issuers shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,

Corporate Trust Office of the Trustee.

     The Issuers may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Issuers

notice to the Trustee of any such designation or rescission and of any change in
location of any such other office or agency.

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.

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

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

                         that, although Holders are not required to tender their
                         Notes, all Notes that are validly tendered shall be
                         accepted for payment;

                                       56

                         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

                    (vi) that Holders shall be entitled to withdraw their

                         Agent, as the case may be, receives, not later than the
                         expiration of the Change of Control Offer, a telegram,

                         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

<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

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

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

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 Sale (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;

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

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

          (iv) 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

                                       59

<PAGE>

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 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;

     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

                                       61

<PAGE>

     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 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 cash or 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.

                                       62

<PAGE>

     (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:

          (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

                                       63

<PAGE>

     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 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"):

                                       64

<PAGE>

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

                                       65

<PAGE>

          or such Restricted Subsidiary, as the case may be, that was not
          permitted by this clause (vi);

          (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

                                       66

<PAGE>

Indebtedness on the date of its incurrence in any manner that complies with this
Section 4.09. An 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

                                       67

<PAGE>

     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;

          (iii) this Indenture, the Notes and the Guarantees;

          (iv) applicable law;

          (v) any instrument governing Indebtedness or Equity Interests 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

     course of business that impose restrictions on the property so acquired of
     the nature described in clause (c) of the preceding sentence;

          (viii) any agreement for the sale or other disposition of a Restricted
     Subsidiary that contains any one or more of the restrictions 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;

                                       68

<PAGE>

          (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

     assets or property in joint venture agreements and other similar
     agreements, including "clawback," "make-well" or "keep-well" agreements, to

     entered into in the ordinary course of business; and

          (xv) restrictions on cash or other deposits or net worth imposed by
     customers under contracts entered into in the ordinary course of business.

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

     covenant and that such Affiliate Transaction has been approved (either
     pursuant to specific or general resolutions) by the Board of Directors of
     the General Partner or has been approved by an officer pursuant to a
     delegation (specific or general) of authority from the Board of Directors

     Affiliate Transactions involving aggregate 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 Affiliate Transaction
     has been approved by a majority of the disinterested members of the Board
     of Directors of the General Partner and (II) either (a) an opinion as to
     the fairness to the Partnership of such Affiliate Transaction from a
     financial point of view issued by an accounting, appraisal or investment

     General Partner shall determine the exact fair market value, provided that
     it shall be within the range so determined by the appraiser), (c) in the
     case of gathering, transportation, marketing, hedging, production handling,

     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

                                       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), for Permitted
Investments or for 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).

                                       72

<PAGE>

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, 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 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

                                       74

<PAGE>

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.

SECTION 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS.

     (a) Neither of the Issuers may, directly or indirectly: (x) consolidate 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 or
     merger (if other than such Issuer) or the Person to which such sale,
     assignment, transfer, lease, conveyance or other disposition shall have
     been made expressly assumes all the obligations of such Issuer under the
     Notes and this Indenture pursuant to agreements reasonably satisfactory to
     the Trustee;

          (iii) immediately after such transaction no Default or Event of
     Default exists;

          (iv) such Issuer or the Person formed by or surviving any such
     consolidation or merger (if other than such Issuer):

               (A) shall have Consolidated Net Worth immediately 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 Charge Coverage Ratio test set forth in Section
          4.09(a); provided, however, that this clause (B) shall be suspended
          during any period in which the Partnership and the Restricted
          Subsidiaries are not subject to the Suspended Covenants; and

                                       75

               (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.

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 reorganization is
     an entity organized or existing under the laws of the United States, any
     state thereof or the District of Columbia;

          (iii) the entity so formed by or resulting from such reorganization
     assumes all of the obligations of the Partnership under the Notes and this
     Indenture pursuant to agreements reasonably satisfactory to the Trustee;

          (iv) immediately after such reorganization no Default or Event of
     Default exists; and

          (v) such reorganization is not adverse to the Holders of the Notes
     (for purposes of this clause (v) it is stipulated that such reorganization
     shall not be considered adverse to the Holders of the Notes solely because
     the successor or survivor of such reorganization (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 giving effect to such transaction, no
Default or Event of Default exists. Any Subsidiary Guarantor may be merged or
consolidated with or into any one or more Subsidiary Guarantors.

                                       76

<PAGE>

     (e) In the event of a sale or other disposition of all or substantially 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 be made in the Notes thereafter to be issued or the Guarantees to
be endorsed thereon as may be appropriate.

                                       77

     (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.

SECTION 6.01. EVENTS OF DEFAULT.

     Each of the following is an Event of Default:

     (a) default for 30 days in the payment when due of interest on, or
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, on
the Notes, whether or not prohibited by the subordination provisions of this
Indenture;

     (c) failure by the Partnership or any of its Restricted Subsidiaries to

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

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,

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
Payment Default or the maturity of which has been so accelerated, aggregates
$20.0 million or more;

     (f) failure by an Issuer or any Restricted Subsidiary of the 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 is a

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 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.

                                       80

<PAGE>

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.

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

                                       81

<PAGE>

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 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.

                                       82

<PAGE>

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.

                                    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).

     (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

                                       83

<PAGE>

          (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

     (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 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.

     (d) The Trustee shall not be liable for any action it takes or omits to
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 shall be
sufficient if signed by an Officer of the Partnership or the General Partner (in
the case of the Partnership), by an Officer of

                                       84

<PAGE>

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.

     (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.

                                       85

<PAGE>

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).

     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.

                                       86

<PAGE>

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
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

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

                                       87

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

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

     The Issuers may, at the option of the Board of Directors of the General
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:

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

would have been the case if such Covenant Defeasance had not occurred;

     (d) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit (other than a Default or Event of Default resulting
from the incurrence of Indebtedness all or a portion of the proceeds of which
shall be applied to such deposit) or insofar as Sections 6.01(h) and 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

Restricted Subsidiary of the Partnership is a party or by which either of the
Issuers or any Restricted Subsidiary of the Partnership is bound;

of preferring the Holders over any other creditors of such Issuer or the
Subsidiary Guarantors or with the intent of defeating, hindering, delaying or
defrauding other creditors of such Issuer; and

                                       91

SECTION 8.05. DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST;
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 from other
funds except to the extent required by law.

     The Issuers and the Subsidiary Guarantors shall pay and indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against the
cash or non-callable U.S. Government Obligations deposited pursuant to Section
8.04 hereof or the principal and interest received in respect thereof other than
any such tax, fee or other charge which by law is for the account of the Holders
of the outstanding Notes.

     Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Issuers from time to time upon the request of the
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 by
an Issuer, in trust for the payment of the principal of, premium, if any,
interest or Liquidated Damages, if any, on any Note and remaining unclaimed for
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
money then remaining shall be repaid to the Issuers.

                                       92

<PAGE>

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;

     (b) to provide for uncertificated Notes in addition to or in place of
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;

     (c) to provide for the assumption of an Issuer's or a Subsidiary
Guarantor's obligations to the Holders of the Notes in the case of a merger or
consolidation or sale of all or substantially all of such Issuer's or Subsidiary
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 this 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 of the
Board of Directors of El Paso Finance and each of the Subsidiary 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.

                                       95

<PAGE>

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.

                                  SUBORDINATION

SECTION 10.01. AGREEMENT TO SUBORDINATE.

     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 and holders of Guarantor Senior Debt shall be
entitled to receive payment in full in cash of all Obligations in respect of
Senior Debt and Guarantor 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:

                                       97

<PAGE>

     (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

     (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 or holders of
such Designated Guarantor Senior Debt.

<PAGE>

     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
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.

                                       99

<PAGE>

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.

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

                                      100

<PAGE>

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.

                                   ARTICLE 11
                                   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

                                      101

<PAGE>

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 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.

                                      102

<PAGE>

     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

                                      103

<PAGE>

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 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

                                      104

<PAGE>

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 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;

                                      105

<PAGE>

     (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.

     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

                                      106

<PAGE>

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, 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.

     If a notice or communication is mailed in the manner provided above within

copy to the Trustee and each Agent at the same time.

Indenture or the Notes. The Issuers, the Subsidiary Guarantors, the Trustee, the
Registrar and anyone else shall have the protection of TIA Section 312(c).

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:

                                      108

<PAGE>

     (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

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.

     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

                                      109

<PAGE>

     (d) a statement as to whether or not, in the opinion of such Person, such

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 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. Each Holder by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes.

CONSTRUE THIS INDENTURE, THE NOTES AND THE GUARANTEES.

SECTION 13.09. NO ADVERSE INTERPRETATION OF OTHER AGREEMENTS.

         8 1/2% [Series A] [Series B] Senior Subordinated Note due 2010

     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1. Interest. El Paso Energy Partners, L.P., a Delaware limited partnership
(the "Partnership"), and El Paso Energy Partners Finance Corporation, a Delaware
corporation ("El Paso Finance" and, together with the Partnership, the
"Issuers"), promise to pay interest on the principal amount of this Note at 8
1/2% per annum and shall pay any Liquidated Damages payable pursuant to Section
5 of the Registration Rights Agreement referred to below. The Issuers will pay
interest and Liquidated Damages, if any, semi-annually on June 1 and December 1
of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Notes will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the Issue Date; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
June 1, 2003. The Issuers shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at the rate then in effect; the Issuers shall
pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year comprised of twelve 30-day months.

     2. Method of Payment. The Issuers will pay interest on the Notes (except
defaulted interest) and Liquidated Damages to the Persons who are registered
Holders of Notes at the close of business on the May 15 or November 15 next
preceding the Interest Payment Date, even if such Notes are cancelled after such
record date and on or before such Interest Payment Date, except as provided in
Section 2.12 of the Indenture with respect to defaulted interest. The Notes will
be payable as to principal, premium and interest and Liquidated Damages, if any,
at the office or agency of the Paying Agent and Registrar maintained for such
purpose within the City and State of New York, or, at the option of the Issuers,
payment of interest and Liquidated Damages, if any, may be made by check mailed
to the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest, premium and Liquidated
Damages, if any, on, all Global Notes and all other Notes the Holders of which
shall have provided wire transfer instructions to the Issuers or the Paying
Agent. Such payment shall be in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts.

     3. Paying Agent and Registrar. Initially, JPMorgan Chase Bank, the Trustee
under the Indenture, will act as Paying Agent and Registrar. The Issuers may
change any Paying Agent or Registrar without notice to any Holder. The Issuers
or any of the Subsidiary Guarantors may act in any such capacity.

those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The Notes are subject to
all such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. To the extent any provision of this Note conflicts with
the express provisions of the Indenture, the provisions of the Indenture shall
govern and be controlling. The Notes are unsecured general obligations of the
Issuers. Payment of the Notes and Guarantees and related obligations are
subordinated to the prior payment in full in cash of Senior Debt and Guarantor

at a redemption price equal to 108.500% of the principal amount thereof, plus
accrued and unpaid interest and Liquidated Damages, if any, thereon, to the
redemption date, with the net cash proceeds of one or more Equity Offerings;
provided that at least 67% of the aggregate principal amount of Notes remains

that such redemption shall occur within 90 days of the date of the closing of
such Equity Offering.

     6. Mandatory Redemption. Except as set forth in paragraph 7 below, the
Issuers shall not be required to make mandatory redemption payments with respect

an integral multiple thereof) of such Holder's Notes (the "Change of Control
Offer") at a purchase price equal to 101% of the

                                Exhibit A Page 5

<PAGE>

aggregate principal amount of the Notes repurchased plus accrued and unpaid
interest, if any, thereon, and Liquidated Damages, if any, thereon, to the date
of purchase. Within 30 days following any Change of Control, the Issuers shall
mail a notice to each Holder setting forth the procedures governing the Change
of Control Offer as required by the Indenture and information regarding such
other matters as is required under Section 4.06 of the Indenture. The Holder of
this Note may elect to have this Note or a portion hereof in an authorized

of Control Offer.

     (b) If the Issuers or any Restricted Subsidiary of the Partnership

to all Holders of Notes and all holders of other Indebtedness that is pari passu
with the Notes containing provisions similar to those set forth in the Indenture
with respect to offers to purchase or redeem with the proceeds of sales of
assets (an "Asset Sale Offer") pursuant to Section 3.09 of the Indenture to
purchase the maximum principal amount of Notes and such other pari passu
Indebtedness that may be purchased out of the Excess Proceeds at an offer price
in cash in an amount equal to 100% of the principal amount thereof plus accrued
and unpaid interest thereon, if any, and Liquidated Damages (in the case of the
Notes) thereon, if any, to the date of purchase in accordance with the
procedures set forth in the Indenture. If the aggregate principal amount of
Notes surrendered by Holders thereof exceeds the amount of Excess Proceeds
allocated for repurchase of Notes, the Trustee shall select the Notes to be
purchased on a pro rata basis. Holders of Notes that are the subject of an offer
to purchase will receive an Asset Sale Offer from the Issuers prior to any
related purchase date and may elect to have such Notes purchased by completing
the form entitled "Option of Holder to Elect Purchase" on the reverse of the
Notes.

     8. Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of

accrue on Notes or portions thereof called for redemption unless the Issuers
defaults in making such redemption payment.

     9. Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Issuers may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuers need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15 days before

and the corresponding Interest Payment Date.

     10. Persons Deemed Owners. The registered Holder of a Note may be treated

     11. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
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. Without
the consent of any Holder of a Note, the Indenture, the Guarantees, or the Notes
may be amended or supplemented to cure any ambiguity, defect or inconsistency,
to provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of an Issuer's or a Subsidiary Guarantor's
obligations to Holders of the Notes in case of a merger or consolidation or sale
of all or substantially all of such Issuer's or Subsidiary Guarantor's assets,
to add or release Subsidiary Guarantors pursuant to the terms of the Indenture,
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
rights under the Indenture of any such Holder, to comply with the requirements
of the SEC in order to effect or maintain the qualification of the Indenture
under the Trust Indenture Act, to evidence or provide for the acceptance of
appointment under the Indenture of a successor Trustee, to add additional Events
of Default or to secure the Notes and/or the Guarantees.

     12. Defaults and Remedies. Events of Default include in summary form: (i)
default for 30 days in the payment when due of interest on or Liquidated
Damages, if any, with respect to the Notes (whether or not prohibited by Article
10 of the Indenture); (ii) default in payment when due of the principal of or
premium, if any, on the Notes (whether or not prohibited by Article 10 of the
Indenture); (iii) failure by the Partnership or any of its Restricted
Subsidiaries to comply with Sections 3.09, 4.06 and 4.07 of the Indenture; (iv)
failure by the Partnership for 60 days after notice to the Issuers by the
Trustee or to the Issuers and the Trustee by Holders of at least 25% in
principal amount of the Notes then outstanding to comply with certain other
agreements in the Indenture or the Notes (provided that no such notice need be
given, and an Event of Default shall occur, 60 days after a failure by an Issuer
or any Restricted Subsidiary of the Partnership to comply with the covenants in
section 4.08, 4.09 or 5.01 of the Indenture, unless theretofore cured); (v)
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 an Issuer or any Restricted Subsidiary of the Partnership (or the
payment of which is guaranteed by an Issuer or any Restricted Subsidiary of the
Partnership), whether such Indebtedness or guarantee now exists, or is created
after the date of the Indenture, if that default (a) 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 (b) results in the acceleration of such
Indebtedness prior to its express maturity 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 Payment Default or the maturity
of which has been so accelerated, aggregates $20.0 million or more; (vi) the
failure by an Issuer or any Restricted Subsidiary of the Partnership to pay
final judgments by courts of competent jurisdiction aggregating in excess of
$10.0 million, which judgments are not paid, discharged or stayed for a period
of 60 days; (vii) except as permitted by the Indenture, any Guarantee of a
Subsidiary Guarantor shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in force and effect
or any Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary

                                Exhibit A Page 7

<PAGE>

Guarantor, shall deny or disaffirm its obligations under its Guarantee; and
(viii) certain events of bankruptcy or insolvency with respect to an Issuer or
any Restricted Subsidiary of the Partnership that is a Significant Subsidiary or
any group of Restricted Subsidiaries that, taken as a whole, would constitute a
Significant Subsidiary. If any Event of Default 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.
Notwithstanding the foregoing, so long as any Credit Facility shall be in full
force and effect, if an Event of Default pursuant to clause (v) above 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. Notwithstanding the foregoing, in the
case of an Event of Default arising from certain events of bankruptcy or
insolvency, with respect to an Issuer, any Restricted Subsidiary of the
Partnership constituting a Significant Subsidiary or any group of Restricted
Subsidiaries of the Partnership that, taken together, would constitute a
Significant Subsidiary, all outstanding Notes will become due and payable
without further action or notice. Holders may not enforce the Indenture or the
Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest.

The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest or Liquidated Damages, if any, on, or the principal or premium, if any,
of the Notes. The Partnership is required to deliver to the Trustee annually a
statement regarding compliance with the Indenture, and the Issuers are required
upon becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.

     13. Ranking. Payment and principal, premium, if any, and interest on, and
other Obligations with respect to, the Notes is subordinated, in the manner and
to the extent set forth in the Indenture, to prior payment in full of all Senior
Debt.

     14. Trustee Dealings with Partnership. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Partnership or its Affiliates, and may otherwise deal with the
Partnership or its Affiliates, as if it were not the Trustee.

     15. No Recourse Against General Partner. The General Partner shall not have
any liability for any Obligations of either of the Issuers or any Subsidiary
Guarantor under the Notes, the Indenture or the Guarantees, or for any claim
based on, in respect of, or by reason of, such Obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.

                                Exhibit A Page 8

<PAGE>

     16. No Recourse Against Others. A past, present or future director,
officer, partner, employee, incorporator, stockholder or member of an Issuer,
the General Partner or any Subsidiary Guarantor, as such, shall not have any
liability for any Obligations of either of the Issuers or any Subsidiary
Guarantor under the Notes, the Indenture or the Guarantees or for any claim
based on, in respect of, or by reason of, such Obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.

manual signature of the Trustee or an authenticating agent.

     18. Abbreviations. Customary abbreviations may be used in the name of a

Certificated Notes shall have all the rights and obligations set forth in the
Registration Rights Agreement dated as of March 24, 2003, among the Issuers, the
Subsidiary Guarantors and the parties named on the signature pages thereof (the
"Registration Rights Agreement").

Committee on Uniform Security Identification Procedures, the Issuers have caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

     The Issuers will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.
