                            INDEMNIFICATION AGREEMENT

         AGREEMENT, effective as of ____________, 200_, between Nabors
Industries Ltd., a Bermuda exempted company (the "Company"), and
________________ (the "Indemnitee").

         WHEREAS, it is essential to the Company to retain and attract as
directors and officers the most capable persons available;

         WHEREAS, Indemnitee is a director or officer of the Company;

         WHEREAS, both the Company and Indemnitee recognize the increased risk
of litigation and other claims being asserted against directors and officers of
public companies in today's environment;

         WHEREAS, the Bye-laws of the Company require the Company to indemnify
and advance expenses to its directors and officers to the full extent permitted
by law and the Indemnitee has been serving and continues to serve as a director
or officer of the Company in part in reliance on such Bye-laws;

         WHEREAS, in recognition of Indemnitee's need for substantial protection
against personal liability in order to enhance Indemnitee's continued service to
the Company in an effective manner and Indemnitee's reliance on the aforesaid
Bye-laws, and in part to provide Indemnitee with specific contractual assurance
that the protection promised by such Bye-laws will be available to Indemnitee
(regardless of, among other things, any amendment to or revocation of such
Bye-laws or any change in the composition of the Company's Board of Directors or
acquisition transaction relating to the Company), the Company wishes to provide
in this Agreement for the indemnification of and the advancing of expenses to
Indemnitee to the fullest extent (whether partial or complete) permitted by law
and as set forth in this Agreement, and, to the extent insurance is maintained,
for the continued coverage of Indemnitee under the Company's directors' and
officers' liability insurance policies;

         NOW, THEREFORE, in consideration of the premises and of Indemnitee
continuing to serve the Company directly or, at its request, another enterprise,
and intending to be legally bound hereby, the parties hereto agree as follows:

                     have occurred if (i) any "person" (as such term is used in

                     Exchange Act of 1934, as amended (the "Act")), other than a

                     employee benefit plan of the Company or a company,
                     corporation, limited liability company or other business
                     entity owned directly or indirectly by the shareholders of
                     the Company in substantially the same proportions as their
                     ownership of shares of the Company, is or becomes the
                     "beneficial owner" (as defined in Rule 13d-3 under the
                     Act), directly or indirectly, of securities of the Company
                     representing 20% or more of the total voting power
                     represented by the Company's then outstanding Voting
                     Securities, or (ii) during any period of two consecutive

                     new director whose election by the Board of Directors or

                     directors then still in office who either were directors at
                     the beginning of the period or whose election or nomination
                     for election was previously so approved, cease for any
                     reason to constitute a majority thereof, or (iii) the
                     shareholders of the Company approve a merger or
                     consolidation of the Company with any other company,
                     corporation, limited liability company or other business
                     entity, other than a merger or consolidation which would
                     result in the voting securities of the Company outstanding
                     immediately prior thereto continuing to represent (either
                     by remaining outstanding or by being converted into voting
                     securities of the surviving entity) at least 80% of the
                     total voting power represented by the voting securities of
                     the Company or such surviving entity outstanding
                     immediately after such merger or consolidation, or the
                     shareholders of the Company approve a plan of complete
                     liquidation of the Company or an agreement for the sale or
                     disposition by the Company of (in one transaction or a
                     series of transactions) all or substantially all the
                     Company's assets.

           (b)       Claim: A "Claim" means any threatened, pending or completed
                     action, suit or proceeding, or any inquiry or
                     investigation, whether instituted by the Company or any
                     other party, that Indemnitee in good faith believes might
                     lead to the institution of any such action, suit or
                     proceeding, whether civil, criminal, administrative,
                     investigative or other.

                     costs, expenses and obligations paid or incurred in
                     connection with investigating, defending, being a witness
                     in or participating in (including on appeal), or preparing
                     to defend, be a witness in or participate in, any Claim
                     relating to any Indemnifiable Event.

           (d)       Indemnifiable Event: An "Indemnifiable Event" means any
                     event or occurrence related to the fact that Indemnitee is
                     or was a director, officer, employee, agent or fiduciary of
                     the Company, or is or was serving at the request of the
                     Company as a director, officer, employee, trustee, agent or
                     fiduciary of another company, corporation, limited
                     liability company, partnership, joint venture, employee
                     benefit plan, trust or other enterprise, or by reason of
                     anything done or not done by Indemnitee in any such
                     capacity.

           (e)       Independent Legal Counsel: "Independent Legal Counsel"
                     means an attorney or firm of attorneys, selected in
                     accordance with the provisions of Section 3 of this
                     Agreement, who shall not have otherwise performed services
                     for the Company or Indemnitee within the last five (5)
                     years (other than with respect to matters concerning the
                     rights of Indemnitee under this Agreement, or of other
                     indemnitees under similar indemnity agreements).

           (f)       Potential Change in Control: A "Potential Change in
                     Control" shall be deemed to have occurred if (i) the
                     Company enters into an agreement, the consummation of which
                     would result in the occurrence of a Change in Control; (ii)
                     any person (including the Company) publicly announces an
                     intention to take or to consider taking actions which if
                     consummated would constitute a Change in Control; (iii) any
                     person, other than a trustee or other fiduciary holding
                     securities under an employee benefit plan of the Company or
                     a company, corporation, limited liability company or other
                     business entity owned, directly or indirectly, by the
                     shareholders of the Company in substantially the same
                     proportions as their ownership of shares of the Company,
                     who is or becomes the beneficial owner, directly or
                     indirectly, of securities of the Company representing 9.5%
                     or more of the combined voting power of the Company's then
                     outstanding Voting Securities, increases his beneficial
                     ownership of such securities by five percentage points (5%)
                     or more over the percentage so owned by such person; or
                     (iv) the Board adopts a resolution to the effect that, for
                     purposes of this Agreement, a Potential Change in Control
                     has occurred.

           (g)       Reviewing Party: A "Reviewing Party" means any appropriate
                     person or body consisting of a member or members of the
                     Company's Board of Directors or any other person or body
                     appointed by the Board who is not a party to the particular
                     Claim for which Indemnitee is seeking indemnification, or
                     Independent Legal Counsel.

           (h)       Voting Securities: "Voting Securities" means any securities
                     of the Company which vote generally in the election of
                     directors.

         2. Basic Indemnification Arrangement. (a) In the event Indemnitee was,
is or becomes a party to or witness or other participant in, or is threatened to
be made a party to or witness or other participant in, a Claim by reason of (or
arising in part out of) an Indemnifiable Event, the Company shall indemnify
Indemnitee to the fullest extent permitted by law as soon as practicable but in
any event no later than thirty (30) days after written demand is presented to
the Company, against any and all Expenses, judgments, fines, penalties and
amounts paid in settlement (including all interest, assessments and other
charges paid or payable in connection with or in respect of such Expenses,
judgments, fines, penalties or amounts paid in settlement) of such Claim. If so
requested by Indemnitee, the Company shall advance immediately, and in any event
within one (1) business day of such request, any and all Expenses to Indemnitee
(an "Expense Advance").

                     (b) Notwithstanding the foregoing, (i) the obligations of
the Company under Section 2(a) shall be subject to the condition that the
Reviewing Party shall not have determined (in a written opinion, in any case in
which the Independent Legal Counsel referred to in Section 3 hereof is involved)
that Indemnitee would not be permitted to be indemnified under applicable law,
and (ii) the obligation of the Company to make an Expense Advance pursuant to
Section 2(a) shall be subject to the condition that, if, when and to the extent
that the Reviewing Party determines that Indemnitee would not be permitted to be
so indemnified under applicable law, the Company shall be entitled to be
reimbursed by Indemnitee (who hereby agrees to reimburse the Company) for all
such amounts theretofore paid; provided, however, that if Indemnitee has
commenced or thereafter commences legal proceedings in a court of competent
jurisdiction to secure a determination that Indemnitee should be indemnified
under applicable law, any determination made by the Reviewing Party that
Indemnitee would not be permitted to be indemnified under applicable law shall
not be binding and Indemnitee shall not be required to reimburse the Company for
any Expense Advance until a final judicial determination

                                       4
<PAGE>

is made with respect thereto (as to which all rights of appeal therefrom have
been exhausted or lapsed). If there has not been a Change in Control, the
Reviewing Party shall be selected by the Board of Directors, and if there has
been such a Change in Control (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control), the Reviewing Party shall be the
Independent Legal Counsel referred to in Section 3 hereof. If there has been no
determination by the Reviewing Party or if the Reviewing Party determines that
Indemnitee substantively would not be permitted to be indemnified in whole or in
part under applicable law, Indemnitee shall have the right to commence
litigation in any court in the Islands of Bermuda or any federal or state court
in any state of the United States, in each case having subject matter
jurisdiction thereof and in which venue is proper seeking an initial
determination by the court or challenging any such determination by the
Reviewing Party or any aspect thereof, including the legal or factual bases
therefor, and the Company hereby consents to service of process and to appear in
any such proceeding. Any determination by the Reviewing Party otherwise shall be
conclusive and binding on the Company and Indemnitee.

         3. Change in Control. The Company agrees that if there is a Change in
Control of the Company (other than a Change in Control which has been approved
by a majority of the Company's Board of Directors who were directors immediately
prior to such Change in Control) then with respect to all matters thereafter
arising concerning the rights of Indemnitee to indemnity payments and Expense
Advances under this Agreement or any other agreement or Company Bye-law now or
hereafter in effect relating to Claims for Indemnifiable Events, the Company
shall seek legal advice only from Independent Legal Counsel selected by
Indemnitee and approved by the Company (which approval shall not be unreasonably
withheld). Such counsel, among other things, shall render its written opinion to
the Company and Indemnitee as to whether and to what extent the Indemnitee would
be permitted to be indemnified under applicable law. The Company agrees to pay
the reasonable fees of the Independent Legal Counsel referred to above and to
indemnify fully such counsel against any and all expenses (including attorneys'
fees), claims, liabilities and damages arising out of or relating to this
Agreement or its engagement pursuant hereto.

         4. Establishment of Trust. In the event of a Potential Change in
Control, the Company shall, upon written request by Indemnitee, create a trust
for the benefit of Indemnitee and from time to time upon written request of
Indemnitee shall fund such trust in an amount sufficient to satisfy any and all
Expenses reasonably anticipated at the time of each such request to be incurred
in connection with investigating, preparing for and defending any Claim relating
to an Indemnifiable Event, and any and

                                       5
<PAGE>

all judgments, fines, penalties and settlement amounts of any and all Claims
relating to an Indemnifiable Event from time to time actually paid or claimed,
reasonably anticipated or proposed to be paid, provided that in no event shall
more than $200,000 be required to be deposited in any trust created hereunder in
excess of amounts deposited in respect of reasonably anticipated Expenses. The
amount or amounts to be deposited in the trust pursuant to the foregoing funding
obligation shall be determined by the Reviewing Party, in any case in which the
Independent Legal Counsel referred to above is involved. The terms of the trust
shall provide that upon a Change in Control (i) the trust shall not be revoked
or the principal thereof invaded, without the written consent of the Indemnitee,
(ii) the trustee shall advance, within two business days of a request by the
Indemnitee, any and all Expenses to the Indemnitee (and the Indemnitee hereby
agrees to reimburse the trust under the circumstances under which the Indemnitee
would be required to reimburse the Company under Section 2(b) of this
Agreement), (iii) the trust shall continue to be funded by the Company in
accordance with the funding obligation set forth above, (iv) the trustee shall
promptly pay to Indemnitee all amounts for which Indemnitee shall be entitled to
indemnification pursuant to this Agreement or otherwise, and (v) all unexpended
funds in such trust shall revert to the Company upon a final determination by
the Reviewing Party or a court of competent jurisdiction, as the case may be,
that Indemnitee has been fully indemnified under the terms of this Agreement.
The trustee shall be chosen by Indemnitee. Nothing in this Section 4 shall
relieve the Company of any of its obligations under this Agreement.

         5. Indemnification for Additional Expenses. The Company shall indemnify
Indemnitee against any and all expenses (including attorneys' fees) and, if
requested by Indemnitee, shall (within two business days of such request)
advance such expenses to Indemnitee, which are incurred by Indemnitee in
connection with any action brought by Indemnitee for (i) indemnification or
advance payment of Expenses by the Company under this Agreement or any other
agreement or Company Bye-law now or hereafter in effect relating to Claims for
Indemnifiable Events and/or (ii) recovery under any directors' and officers'
liability insurance policies maintained by the Company, regardless of whether
Indemnitee ultimately is determined to be entitled to such indemnification,
advance expense payment or insurance recovery, as the case may be.

         6. Partial Indemnity, Etc. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of the Expenses, judgments, fines, penalties and amounts paid in
settlement of a Claim but not, however, for all of the total amount thereof, the
Company shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled. Moreover, notwithstanding any other provision of this

                                       6
<PAGE>

Agreement, to the extent that Indemnitee has been successful on the merits or
otherwise in defense of any or all Claims relating in whole or in part to an
Indemnifiable Event or in defense of any issue or matter therein, including
dismissal without prejudice, Indemnitee shall be indemnified against all
Expenses incurred in connection therewith.

         7. Burden of Proof. In connection with any determination by the
Reviewing Party or otherwise as to whether Indemnitee is entitled to be
indemnified hereunder the burden of proof shall be on the Company to establish
that Indemnitee is not so entitled.

         8. No Presumptions. For purposes of this Agreement, the termination of
any claim, action, suit or proceeding, by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that Indemnitee
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law. In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief.

         9. Nonexclusivity, Etc. The rights of the Indemnitee hereunder shall be
in addition to any other rights Indemnitee may have under the Company's Bye-laws
or The Companies Act 1981 (Bermuda), as amended (the "Companies Act"), or
otherwise. To the extent that a change in the Companies Act (whether by statute
or judicial decision) permits greater indemnification by agreement than would be
afforded currently under the Company's Bye-laws and this Agreement, it is the
intention of the parties hereto that Indemnitee shall enjoy by this Agreement
the greater benefits so afforded by such change.

         10. Liability Insurance. To the extent the Company maintains an
insurance policy or policies providing directors' and officers' liability
insurance, Indemnitee shall be covered by such policy or policies, in accordance
with its or their terms, to the maximum extent of the coverage available for any
Company director or officer.

                                       7
<PAGE>

         11. Period of Limitations. No legal action shall be brought and no
cause of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
period of limitations is otherwise applicable to any such cause of action such
shorter period shall govern.

         12. Amendments, Etc. No supplement, modification or amendment of this
Agreement shall be binding unless executed in writing by both of the parties
hereto. No waiver of any of the provisions of this Agreement shall be deemed or
shall constitute a waiver of any other provisions hereof (whether or not
similar) nor shall such waiver constitute a continuing waiver.

         13. Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all papers required and shall do
everything that may be necessary to secure such rights, including the execution
of such documents necessary to enable the Company effectively to bring suit to
enforce such rights.

         14. No Duplication of Payments. The Company shall not be liable under
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Bye-law or otherwise) of the amounts otherwise
indemnifiable hereunder.

         15. Binding Effect, Etc. This Agreement shall be binding upon and inure
to the benefit of and be enforceable by the parties hereto and their respective
successors or assigns, including any direct or indirect successor by purchase,
merger, consolidation or otherwise to all or substantially all of the business
and/or assets of the Company, spouses, heirs, executors and personal and legal
representatives. This Agreement shall continue in effect regardless of whether
Indemnitee continues to serve as an officer or director of the Company or of any
other enterprise at the Company's request.

         16. Severability. The provisions of this Agreement shall be severable
in the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable in any respect, and
the validity and enforceability of any such provision in every other respect and
of

                                       8
<PAGE>

the remaining provisions hereof shall not be in any way impaired and shall
remain enforceable to the fullest extent permitted by law.

         17. Governing Law. This Agreement shall be governed by and construed
and enforced in accordance with the laws of England applicable to contracts made
and to be performed in such jurisdiction without giving effect to the principles
of conflicts of laws.

                                       9

      SECOND SUPPLEMENTAL INDENTURE dated as of February 14, 2003, among
Enterprise Products Operating L.P., a Delaware limited partnership (the
"Issuer"), Enterprise Products Partners L.P., a Delaware limited partnership
(the "Guarantor"), and Wachovia Bank, National Association, a national banking
association and successor to First Union National Bank, as trustee (the
"Trustee"). Each capitalized term used but not defined in this Second
Supplemental Indenture shall have the meaning assigned to such term in the
Original Indenture (as defined below).

                                    RECITALS:

      WHEREAS, the Issuer and the Guarantor have executed and delivered to the
Trustee an Indenture, dated as of March 15, 2000 (the "Original Indenture" and
as supplemented by this Second Supplemental Indenture, the "Indenture"),
providing for the issuance by the Issuer from time to time of its unsecured
debentures, notes, bonds or other evidences of indebtedness to be issued in one
or more series unlimited as to principal amount (the "Debt Securities"), and the
guaranties by Guarantor of the Debt Securities (the "Guaranties");

      WHEREAS, the Issuer has duly authorized and desires to cause to be issued
pursuant to the Original Indenture and this Second Supplemental Indenture two
series of Debt Securities designated the "6.875% Series A Senior Notes due 2033"
(the "Series A Notes") and the "6.875% Series B Senior Notes due 2033" (the
"Series B Notes" and, together with the Series A Notes, the "Notes"), all of
such Notes to be guaranteed by the Guarantor as provided in Article XIV of the
Original Indenture;

      WHEREAS, the Issuer desires to cause the issuance of the Notes pursuant to
Sections 2.01 and 2.03 of the Original Indenture, which sections permit the
execution of indentures supplemental thereto to establish the form and terms of
Debt Securities of any series;

      WHEREAS, pursuant to Section 9.01 of the Original Indenture, the Issuer
and the Guarantor have requested that the Trustee join in the execution of this
Second Supplemental Indenture to establish the form and terms of the Notes;

      WHEREAS, all things necessary have been done to make the Notes, when
executed by the Issuer and authenticated and delivered hereunder and under the
Original Indenture and duly issued by the Issuer, and the Guaranties, when the
Notes are duly issued by the Issuer, the valid obligations of the Issuer and the
Guarantor, respectively, and to make this Second Supplemental Indenture a valid
agreement of the Issuer and the Guarantor enforceable in accordance with its
terms.

      NOW, THEREFORE, the Issuer, the Guarantor and the Trustee hereby agree
that the following provisions shall supplement the Original Indenture:

                                    ARTICLE I
                                    THE NOTES

      SECTION 1.1 Form.
<PAGE>
      The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A to this Second Supplemental Indenture,
which is hereby incorporated into this Second Supplemental Indenture. The terms
and provisions contained in the Notes shall constitute, and are hereby expressly
made, a part of this Second Supplemental Indenture and to the extent applicable,
the Issuer, the Guarantor and the Trustee, by their execution and delivery of
this Second Supplemental Indenture, expressly agree to such terms and provisions
and to be bound thereby.

      The Series A Notes and the Series B Notes shall be treated as a single
series of Debt Securities for purposes of determining whether Holders of the
requisite principal amount of Notes have given any notice, consent or waiver or
taken any other action permitted under the Indenture.

      The Notes shall be issued only as Registered Securities. The Notes shall
be issued upon original issuance in whole in the form of one or more Global
Securities (the "Book-Entry Notes"). Each Book-Entry Note shall represent such
of the Outstanding Notes as shall be specified therein and shall provide that it
shall represent the aggregate amount of Outstanding Notes from time to time
endorsed thereon and that the aggregate amount of Outstanding Notes represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions. Any endorsement of a Book-Entry Note to
reflect the amount, or any increase or decrease in the amount, of Outstanding
Notes represented thereby shall be made by the Trustee in accordance with
written instructions or such other written form of instructions as is customary
for the Depositary, from the Depositary or its nominee on behalf of any Person
having a beneficial interest in the Book-Entry Note.

      The Issuer initially appoints The Depository Trust Company to act as
Depositary with respect to the Book-Entry Notes.

      SECTION 1.2 Title, Amount and Payment of Principal and Interest.

      The Series A Notes shall be entitled the "6.875% Series A Senior Notes due
2033," and the Series B Notes shall be entitled the "6.875% Series B Senior
Notes due 2033." The Trustee shall authenticate and deliver (i) Series A Notes
for original issue on the Issue Date (the "Original Series A Notes") in the
aggregate principal amount of $500,000,000, (ii) additional Series A Notes for
original issue from time to time after the Issue Date in such principal amounts
as may be specified in the Company Order described in this sentence and (iii)
Series B Notes for original issue from time to time thereafter for issue only in
exchange for a like principal amount of Series A Notes, in each case upon a
Company Order for the authentication and delivery thereof and satisfaction of
the other provisions of Section 2.05 of the Indenture. Such order shall specify
the amount of the Notes to be authenticated, the date on which the original
issue of Notes is to be authenticated, whether the Notes are Series A Notes or
Series B Notes, and the name or names of the initial Holder or Holders. The
aggregate principal amount of Notes that may be outstanding at any time may not
exceed $500,000,000 plus such additional principal amounts as may be issued and
authenticated pursuant to clause (ii) of this paragraph (except as provided in
Section 2.09 of the Indenture).

                                       2
<PAGE>
      The principal amount of each Note shall be payable on March 1, 2033. Each
Series A Note shall bear interest from the date of original issuance, or the
most recent date to which interest has been paid, at the fixed rate of 6.875%
per annum. Each Series B Note shall bear interest at the same rate from the most
recent date to which interest shall have been paid on the Series A Note for
which such Series B Note was exchanged or, if no interest shall have been paid
on such Series A Note, then from the date of original issuance of such Series A
Note. The dates on which interest on the Notes shall be payable shall be March 1
and September 1 of each year, commencing September 1, 2003 in the case of the
Original Series A Notes (the "Interest Payment Dates"). The regular record date
for interest payable on the Notes on any Interest Payment Date shall be the
February 15 or August 15 (the "Regular Record Date"), as the case may be, next
preceding such Interest Payment Date.

      Payments of principal of, premium, if any, and interest due on the Notes
representing Book-Entry Notes on any Interest Payment Date or at maturity will
be made available to the Trustee by 11:00 a.m., New York City time, on such
date, unless such date falls on a day which is not a Business Day, in which case
such payments will be made available to the Trustee by 11:00 a.m., New York City
time, on the next Business Day. As soon as possible thereafter, the Trustee will
make such payments to the Depositary.

      SECTION 1.3 Registrar and Paying Agent.

      The Issuer initially appoints the Trustee as Registrar and paying agent
with respect to the Notes. The office where Notes may be presented for
registration of transfer or exchange and the Place of Payment for the Notes
shall initially be the corporate trust office of the Trustee in the Borough of
Manhattan, The City of New York.

      SECTION 1.4 Transfer and Exchange.

            (i) Transfer and Exchange of Notes in Definitive Form. In addition
to the requirements set forth in Section 2.07 of the Original Indenture, Notes
in definitive form that are Registrable Securities under the Registration Rights
Agreement referred to in Section 1.6 hereof (the "Transfer Restricted
Securities") presented or surrendered for registration of transfer or exchange
pursuant to Section 2.07 of the Original Indenture shall be accompanied by the
following additional information and documents, as applicable, upon which the
Registrar may conclusively rely:

                  (a) if such Transfer Restricted Securities are being delivered
      to the Registrar by a Holder for registration in the name of such Holder,
      without transfer, a certification from such Holder to that effect (in
      substantially the form of Exhibit B hereto); or

                  (b) if such Transfer Restricted Securities are being
      transferred (1) to a "qualified institutional buyer" (as defined in Rule
      144A under the Securities Act) in accordance with Rule 144A under the
      Securities Act or (2) pursuant to an exemption from registration in
      accordance with Rule 144 under the Securities Act (and based upon an
      opinion of counsel if the Issuer or the Trustee so requests) or (3)
      pursuant to an

                                       3
<PAGE>
      effective registration statement under the Securities Act, a certification
      to that effect from such Holder (in substantially the form of Exhibit B
      hereto); or

                  (c) if such Transfer Restricted Securities are being
      transferred pursuant to an exemption from registration in accordance with
      Rule 904 of Regulation S under the Securities Act, certifications to that
      effect from such Holder (in substantially the form of Exhibits B and C
      hereto) and an opinion of counsel to that effect if the Issuer or the
      Trustee so requests; or

                  (d) if such Transfer Restricted Securities are being
      transferred in reliance on and in compliance with another exemption from
      the registration requirements of the Securities Act, a certification to
      that effect from such Holder (in substantially the form of Exhibit B
      hereto) and an opinion of counsel to that effect if the Issuer or the
      Trustee so requests.

            (ii) Transfer and Exchange of Global Notes. The transfer and
exchange of Notes or beneficial interests therein shall be effected through the
Depositary, in accordance with Section 2.15 of the Original Indenture and
Article I of this Second Supplemental Indenture (including the restrictions on
transfer set forth therein and herein) and the rules and procedures of the
Depositary therefor, which shall include restrictions on transfer comparable to
those set forth therein and herein to the extent required by the Securities Act
of 1933, as amended.

      SECTION 1.5 Legends.

            (i) Except as permitted by the following paragraphs (ii) and (iii)
immediately below, each certificate evidencing the Book-Entry Notes and Notes in
definitive form (and all Notes issued in exchange therefor or substitution
thereof) shall bear a legend in substantially the following form:

      THE ISSUANCE AND SALE OF THIS SECURITY (AND ANY GUARANTEE HEREOF) HAVE NOT
      BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
      "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND NEITHER THIS SECURITY

      LAWS.

      THE HOLDER HEREOF, BY ITS ACCEPTANCE OF THIS SECURITY, AGREES FOR THE
      BENEFIT OF THE ISSUER THAT THIS SECURITY MAY NOT BE OFFERED, SOLD, PLEDGED

      SUBSIDIARIES, (2) SO LONG AS THIS SECURITY IS ELIGIBLE FOR RESALE PURSUANT
      TO RULE 144A UNDER THE SECURITIES ACT ("RULE 144A"), TO A PERSON WHOM THE
      SELLER REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" WITHIN THE
      MEANING OF RULE 144A PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF
      A QUALIFIED INSTITUTIONAL BUYER, IN EACH CASE TO WHOM NOTICE IS GIVEN THAT
      THE RESALE, PLEDGE OR OTHER TRANSFER IS BEING MADE IN RELIANCE ON RULE
      144A (AS INDICATED BY THE BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE
      OF TRANSFER, IF APPLICABLE), (3) TO A NON-"U.S. PERSON" IN AN "OFFSHORE
      TRANSACTION" (AS SUCH TERMS ARE DEFINED IN REGULATION S UNDER THE
      SECURITIES ACT) IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT
      (AS INDICATED BY THE BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE OF
      TRANSFER, IF APPLICABLE), (4) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION
      FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, INCLUDING THE
      EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT, IF AVAILABLE, IN
      EACH CASE IN A MINIMUM PRINCIPAL AMOUNT OF $1,000, OR (5) PURSUANT TO AN
      EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, SUBJECT TO EACH
      OF THE FOREGOING CASES TO ANY REQUIREMENT OF LAW THAT THE DISPOSITION OF
      ITS PROPERTY OR THE PROPERTY OF SUCH INVESTOR ACCOUNT OR ACCOUNTS BE AT
      ALL TIMES WITHIN ITS OR THEIR CONTROL, AND SUBJECT TO THE RIGHT OF THE
      ISSUER OR THE TRUSTEE FOR THE SECURITIES PRIOR TO ANY SUCH SALE, PLEDGE OR
      OTHER TRANSFER TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL,
      CERTIFICATIONS AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS
      LEGEND WILL BE REMOVED UPON REQUEST OF THE HOLDER ON OR AFTER THE RESALE
      RESTRICTION TERMINATION DATE.

      In addition, if any of the Notes are issued in reliance on Regulation S
promulgated under the Securities Act, then such Notes shall also bear a legend
substantially in the following form:

      THIS NOTE IS A GLOBAL SECURITY ISSUED IN RELIANCE ON REGULATION S
      PROMULGATED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
      "SECURITIES ACT"). PRIOR TO THE EXPIRATION OF THE DISTRIBUTION COMPLIANCE
      PERIOD WHICH SHALL EXTEND FOR A PERIOD OF FORTY (40) DAYS AFTER THE DATE
      ON WHICH THE NOTES EVIDENCED HEREBY ARE FIRST OFFERED TO PERSONS OTHER

      THE OFFERING, WHICHEVER IS LATER, BENEFICIAL INTERESTS HEREIN MAY NOT BE
      HELD BY ANY PERSON OTHER THAN (1) A NON-U.S. PERSON OR (2) A U.S. PERSON
      WHO PURCHASED SUCH INTEREST IN A TRANSACTION

                                       5
<PAGE>
      EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT PURSUANT TO RULE 144A
      PROMULGATED THEREUNDER. BENEFICIAL INTERESTS HEREIN ARE NOT EXCHANGEABLE
      FOR PHYSICAL NOTES OTHER THAN IN ACCORDANCE WITH THE TERMS OF THE
      INDENTURE. THE TERMS IN THIS LEGEND ARE USED AS USED IN REGULATION S UNDER
      THE SECURITIES ACT.

            (ii) Upon any sale or transfer of a Transfer Restricted Security
(including any Transfer Restricted Security represented by a Book-Entry Note)
pursuant to Rule 144 under the Securities Act or an effective registration
statement under the Securities Act, which shall be certified to the Trustee and
Registrar upon which each may conclusively rely:

                  (a) in the case of any Transfer Restricted Security in
      definitive form, the Registrar shall permit the Holder thereof to exchange
      such Transfer Restricted Security for a Note in definitive form that does
      not bear the legend(s) set forth in (i) above and rescind any restriction
      on the transfer of such Transfer Restricted Security; and

                  (b) in the case of any Transfer Restricted Security
      represented by a Book-Entry Note, such Transfer Restricted Security shall
      not be required to bear the legend(s) set forth in (i) above if all other
      interests in such Global Note have been or are concurrently being sold or
      transferred pursuant to Rule 144 under the Securities Act or pursuant to
      an effective registration statement under the Securities Act, but such
      Transfer Restricted Security shall continue to be subject to the
      provisions of Section 2.15 of the Original Indenture and Section 1.4(ii)
      of this Second Supplemental Indenture.

            (iii) Notwithstanding the foregoing, upon consummation of the
Exchange Offer (as defined in the Registration Rights Agreement), the Issuer
shall issue and, upon receipt of a Company Order in accordance with Section 2.05
of the Original Indenture, the Trustee shall authenticate Series B Notes in
exchange for Series A Notes accepted for exchange in the Exchange Offer, which
Series B Notes shall not bear the legend(s) set forth in (i) above, and the
Registrar shall rescind any restriction on the transfer of such Series B Notes,
in each case unless the Holder of such Series A Notes is either (A) a
broker-dealer tendering Series A Notes acquired directly from the Issuer, (B) a
Person participating in the Exchange Offer for purposes of distributing the
Series B Notes or (C) a Person who is an "affiliate" (as defined in Rule 144
under the Securities Act) of the Issuer. The Issuer shall identify to the
Trustee such Holders of the Notes in a written certification signed by an
Officer of the General Partner and, absent certification from the Issuer to such
effect, the Trustee shall assume that there are no such Holders.

      SECTION 1.6 Registration Rights Agreement.

      Holders of the Notes shall have the benefit of the Company's registration
obligations with respect to the Notes under the Registration Rights Agreement
dated February 14, 2003 by and among the Issuer, the Guarantor and the Initial

                     6.875% SERIES __ SENIOR NOTES DUE 2033

      This Security is one of a duly authorized issue of unsecured debentures,
notes or other evidences of indebtedness of the Company (the "Debt Securities")
of the series hereinafter specified, all issued or to be issued under and
pursuant to the Indenture, to which Indenture reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company, the Guarantor and the Holders
of the Debt Securities. The Debt Securities may be issued in one or more series,
which different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest (if any) at different rates, may be
subject to different sinking, purchase or analogous funds (if any) and may
otherwise vary as provided in the Indenture. This Security is one of a series
designated as the 6.875% Series __ Senior Notes due 2033 of the Company, in
initial aggregate principal amount of $500,000,000 (the "Securities").

1.    Interest.

      The Company promises to pay interest on the principal amount of this
Security at the rate of 6.875% per annum.

      The Company will pay interest semi-annually on March 1 and September 1 of
each year (each an "Interest Payment Date"), commencing September 1, 2003.
Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid on the Securities, from
February 14, 2003. Interest will be computed on the basis of a 360-day year
consisting of twelve 30-day months. The Company shall pay interest (including
post-petition interest in any proceeding under any applicable bankruptcy laws)
on overdue installments of interest (without regard to any applicable grace
period) and on overdue principal and premium, if any, from time to time on
demand at the same rate per annum, in each case to the extent lawful.

2.    Method of Payment.

      The Company shall pay interest on the Securities (except Defaulted
Interest) to the persons who are the registered Holders at the close of business
on the Regular Record Date immediately preceding the Interest Payment Date. Any
such interest not so punctually paid or duly provided for ("Defaulted Interest")
may be paid to the persons who are registered Holders at the close of business
on a special record date for the payment of such Defaulted Interest, or in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which such Securities may then be listed if such manner of payment
shall be deemed practicable by the Trustee, as more fully provided in the
Indenture. The Company shall pay principal, premium, if any, and interest in
such coin or currency of the United States of America as at the time of payment
shall be legal tender for payment of public and private debts. Payments in
respect of a Global Security (including principal, premium, if any, and
interest) will be made by wire transfer of immediately available funds to the
accounts specified by the Depositary. Payments in respect of Securities in
definitive form (including principal, premium, if any, and

                                      A-4
<PAGE>
interest) will be made at the office or agency of the Company maintained for
such purpose within the Borough of Manhattan, The City of New York, which
initially will be at the corporate trust office of the Trustee located at 1 Penn
Plaza, Suite 1414, New York, New York 10119, or, at the option of the Company,
payment of interest may be made by check mailed to the Holders on the relevant
record date at their addresses set forth in the Debt Security Register of
Holders. The Holder must surrender this Security to a paying agent to collect
payment of principal.

3.    Paying Agent and Registrar.

      Initially, Wachovia Bank, National Association will act as paying agent
and Registrar. The Company may change any paying agent or Registrar at any time
upon notice to the Trustee and the Holders. The Company or any of its
Subsidiaries may, subject to certain exceptions, act as paying agent or
Registrar.

4.    Indenture.

      This Security is one of a duly authorized issue of Debt Securities of the
Company issued and to be issued in one or more series under the Indenture.

      Capitalized terms herein are used as defined in the Indenture unless
otherwise defined herein. The terms of the Securities include those stated in
the Indenture as originally executed those made part of the Indenture by
reference to the TIA, as in effect on the date of the Indenture, and those terms
stated in the Second Supplemental Indenture. The Securities are subject to all
such terms, and Holders of Securities are referred to the Indenture as
originally executed, the Second Supplemental Indenture and the TIA for a
statement of them. The Securities of this series are general unsecured
obligations of the Company limited to an initial aggregate principal amount of
$500,000,000; provided, however, that the authorized aggregate principal amount
of such series may be increased from time to time as provided in the Second
Supplemental Indenture.

5.    Redemption.

      The Securities are redeemable, at the option of the Company, at any time
in whole, or from time to time in part, at a redemption price (the "Make-Whole
Price") equal to the greater of: (i) 100% of the principal amount of the
Securities to be redeemed; or (ii) the sum of the present values of the
remaining scheduled payments of principal and interest (at the rate in effect on
the date of calculation of the redemption price) on the Securities (exclusive of
interest accrued to the Redemption Date) discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the applicable Treasury Yield plus 35 basis points; plus, in either case,
accrued interest to the Redemption Date.

      Securities called for redemption become due on the Redemption Date.
Notices of redemption will be mailed at least 30 but not more than 60 days
before the Redemption Date to each Holder of the Securities to be redeemed at
its registered address. The notice of redemption for the Securities will state,
among other things, the amount of Securities to be redeemed, the Redemption
Date, the Make-Whole Price and the place(s) that payment will be made upon
presentation and surrender of Securities to be redeemed. Unless the Company
defaults in payment of the Make-Whole Price, interest will cease to accrue on
any Securities that have been

                                      A-5
<PAGE>
called for redemption at the Redemption Date. If less than all the Securities
are redeemed at any time, the Trustee will select the Securities to be redeemed
on a pro rata basis or by any other method the Trustee deems fair and
appropriate.

      For purposes of determining the Make-Whole Price, the following
definitions are applicable:

      "Treasury Yield" means, with respect to any Redemption Date applicable to
the Securities, the rate per annum equal to the semi-annual equivalent yield to
maturity (computed as of the third Business Day immediately preceding such
Redemption Date) of the Comparable Treasury Issue, assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the applicable Comparable Treasury Price for the Redemption Date.

      "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable to
the remaining term of the Securities that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining
terms of the Securities; provided, however, that if no maturity is within three
months before or after the maturity date for the Securities, yields for the two
published maturities most closely corresponding to such United States Treasury
security will be determined and the treasury rate will be interpolated or
extrapolated from those yields on a straight line basis rounding to the nearest
month.

      "Independent Investment Banker" means Wachovia Securities, Inc. (and its
successors), or, if such firm is unwilling or unable to select the applicable
Comparable Treasury Issue, an independent investment banking institution of
national standing appointed by the Trustee and reasonably acceptable to the
Company.

      "Comparable Treasury Price" means, with respect to any Redemption Date,
(a) the bid price for the Comparable Treasury Issue (expressed as a percentage
of its principal amount) at 4:00 p.m. on the third Business Day preceding the
Redemption Date, as set forth on "Telerate Page 500" (or such other page as may
replace Telerate Page 500), or (b) if such page (or any successor page) is not
displayed or does not contain such bid prices at such time, the average of the
Reference Treasury Dealer Quotations obtained by the Trustee for the Redemption
Date.

      "Reference Treasury Dealer" means (a) Wachovia Securities, Inc. (and its
successors) and (b) one other primary U.S. government securities dealer in New
York City selected by the Independent Investment Banker (each, a "Primary
Treasury Dealer"); provided, however, that if either of the foregoing shall
cease to be a Primary Treasury Dealer, the Issuer will substitute therefor
another Primary Treasury Dealer.

      "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any Redemption Date for the Securities, an
average, as determined by the Trustee, of the bid and asked prices for the
Comparable Treasury Issue for the Securities (expressed in each case as a
percentage of its principal amount) quoted in writing to the Trustee by such
Reference

                                      A-6
<PAGE>
Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day
preceding such Redemption Date.

      Except as set forth above, the Securities will not be redeemable prior to
their Stated Maturity and will not be entitled to the benefit of any sinking
fund.

      The Securities may be redeemed in part in multiplies of $1,000 only. Any
such redemption will also comply with Article III of the Indenture.

6.    Denominations; Transfer; Exchange.

      The Securities are to be issued in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000 in excess thereof. A
Holder may register the transfer of, or exchange, Securities in accordance with
the Indenture. The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and
fees required by law or permitted by the Indenture.

7.    Person Deemed Owners.

      The registered Holder of a Security may be treated as the owner of it for
all purposes.

8.    Amendment; Supplement; Waiver.

      Subject to certain exceptions, the Indenture may be amended or
supplemented, and any existing Event of Default or compliance with any provision
may be waived, with the consent of the Holders of a majority in principal amount
of the Outstanding Debt Securities of each series affected. Without consent of
any Holder of a Security, the parties thereto may amend or supplement the
Indenture to, among other things, cure any ambiguity or omission, to correct any
defect or inconsistency, or to make any other change that does not adversely
affect the rights of any Holder of a Security. Any such consent or waiver by the
Holder of this Security (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future Holders and owners
of this Security and any Securities which may be issued in exchange or
substitution herefor, irrespective of whether or not any notation thereof is
made upon this Security or such other Securities.

9.    Defaults and Remedies.

      If an Event of Default with respect to the Securities occurs and is
continuing, then in every such case the Trustee or the Holders of not less than
25% in principal amount of the Securities then Outstanding may declare the
principal amount of all the Securities to be due and payable immediately in the
manner and with the effect provided in the Indenture. Notwithstanding the
preceding sentence, however, if at any time after such a declaration of
acceleration has been made and before judgment or decree for payment of the
money due has been obtained by the Trustee as provided in the Indenture, the
Holders of a majority in principal amount of the Outstanding Securities, by
written notice to the Trustee, may rescind and annul such declaration and its
consequences if all Events of Default under the Indenture with respect to the
Securities, other than the nonpayment of the principal or interest which has
become due solely by such declaration acceleration, shall have been cured or
shall have been waived. No

                                      A-7
<PAGE>
such rescission shall affect any subsequent default or shall impair any right
consequent thereon. Holders of Securities may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may require
indemnity satisfactory to it before it enforces the Indenture or the Securities.
Subject to certain limitations, Holders of a majority in aggregate principal
amount of the Securities then outstanding may direct the Trustee in its exercise
of any trust or power.

10.   Registration Rights.

      The Holder of this Security is entitled to the benefits of the
Registration Rights Agreement (the "Registration Rights Agreement") dated as of
February 14, 2003, by and among the Company, the Guarantor and the Initial
Purchasers named therein. In certain events, the Company shall be required to
pay to each affected Holder additional interest on the Securities, on the terms
and subject to the conditions of the Registration Rights Agreement.

11.   Trustee Dealings with Company.

      The Trustee under the Indenture, in its individual or any other capacity,
may make loans to, accept deposits from, and perform services for the Company or
its Affiliates or any subsidiary of the Company's Affiliates, and may otherwise
deal with the Company or its Affiliates as if it were not the Trustee.

12.   Authentication.

      This Security shall not be valid until the Trustee signs the certificate
of authentication on the other side of this Security.

13.   Abbreviations and Defined Terms.

      Customary abbreviations may be used in the name of a Holder of a Security
or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the
entireties), JT TEN (joint tenants with right of survivorship and not as tenants
in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

14.   CUSIP Numbers.

      Pursuant to a recommendation promulgated by the Committee on Uniform Note
Identification Procedures, the Company has caused CUSIP numbers to be printed on
the Securities as a convenience to the Holders of the Securities. No
representation is made as to the accuracy of such number as printed on the
Securities and reliance may be placed only on the other identification numbers
printed hereon.

15.   Absolute Obligation.

      No reference herein to the Indenture and no provision of this Security or
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Security in the manner, at the respective times, at the rate
and in the coin or currency herein prescribed.

                                      A-8
<PAGE>
16.   No Recourse.

      The General Partner and its directors, officers, employees and members, as
such, shall have no liability for any obligations of the Guarantor or the Issuer
under the Securities, the Indenture or the Guarantee or for any claim based on,
in respect of, or by reason of, such obligations or their creation. Each Holder
by accepting the Securities waives and releases all such liability. The waiver
and release are part of the consideration for issuance of the Securities.

17.   Governing Law.

      This Security shall be construed in accordance with and governed by the
laws of the State of New York.

18.   Guarantee.

      The Securities are fully and unconditionally guaranteed on an unsecured,
unsubordinated basis by the Guarantor as set forth in Article XIV of the
Indenture, as noted in the Notation of Guarantee to this Security.

                                      A-9

      (ii)  at the time the buy order was originated, the transferee was outside
            the United States or we and any person acting on our behalf
            reasonably believed that the transferee was outside the United
            States;

      (iii) no directed selling efforts have been made by us in the United
            States in contravention of the requirements of Rule 903(a) or Rule
            904(a) of Regulation S under the U.S. Securities Act of 1933, as
            applicable; and
