      (a) General.  The
Securities and the Trustee’s certificate of authentication shall be
substantially in the form of Exhibit A to this Indenture, the terms of which are
hereby incorporated into this Indenture.  The Securities may have
notations, legends or endorsements required by law, securities exchange rule,
the Company’s certificate of incorporation, memorandum of association, articles
of association, other organizational documents, agreements to which the Company
is subject, if any, or usage; provided
that any such notation, legend or endorsement is in a form acceptable to the
Company. Each Security shall be dated the date of its
authentication.  The Securities shall be in registered form without
coupons and only in denominations of $1,000 and any integral multiples
thereof.  The terms and provisions contained in the Securities shall
constitute, and are hereby expressly made, a part of this Indenture and to the
extent applicable, the Company and the Trustee, by their execution and delivery
of this Indenture, expressly agree to such terms and provisions and to be bound
thereby.

       

      (b) Global
Securities.  Series A Securities offered and sold to a QIB in
reliance on Rule 144A under the Securities Act (“Rule
144A”) or in reliance on Regulation S under the Securities Act (“Regulation
S”) shall be issued initially in the form of one or more permanent global
Securities in definitive, fully registered form without interest coupons with
the global securities legend and restricted securities legend set forth in
Section 2.06 (each, a “Global
Security”), which shall be deposited on behalf of the purchasers of the
Series A Securities represented thereby with the Trustee, at its New York
office, as custodian for the Depositary (or with such other custodian as the
Depositary may direct), and registered in the name of the Depositary or a
nominee of the Depositary, duly executed by the Company and authenticated by the
Trustee as hereinafter provided. The aggregate principal amount of the Global
Securities may from time to time be increased or decreased by adjustments made
on the records of the Trustee and the Depositary or its nominee as hereinafter
provided.

       

      (c) Book-entry
Provisions.  This Section 2.01(c) shall apply only to a Global
Security deposited with or on behalf of the Depositary.

       

      
        
          
          

        

        
          -15-

          
            

          

        

        
          
          

        

      

      The Company shall
execute and the Trustee shall, in accordance with this Section 2.01(c),
authenticate and deliver initially one or more Global Securities that (i) shall
initially be registered in the name of the Depositary for such Global Security
or Global Securities or the nominee of such Depositary and (ii) shall be
delivered by the Trustee to such Depositary or pursuant to such Depositary’s
instructions or held by the Trustee as custodian for the
Depositary.

       

      Members of, or
participants in (“Agent
Members”), the Depositary (including Euroclear and Clearstream) shall
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depositary or by the Trustee as the custodian of the
Depositary or under such Global Security, and the Depositary may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Agent Members, the operation of
customary practices of such Depositary governing the exercise of the rights of a
holder of a beneficial interest in any Global Security.

       

      (d) Certificated
Securities.  Except as provided in this Section 2.01 or Section
2.06, owners of beneficial interests in Global Securities will not be entitled
to receive physical delivery of certificated Securities.

       

      (e) Euroclear
and Clearstream Procedures Applicable.  The provisions of the
“Operating Procedures of the Euroclear System” and “Terms and Conditions
Governing Use of Euroclear” and the equivalent procedures of Clearstream shall
be applicable to transfers of beneficial interests in Global Securities that are
held by Agent Members (as defined below) through Euroclear or
Clearstream.

       

      (f) Additional
Securities.  Subject to compliance with the provisions of
Section 3.08, the Company may issue Additional Securities under this Indenture
after the Initial Issue Date in an unlimited aggregate principal
amount.

       

      
        	
                Section
      2.02  

              	
                Execution
      and Authentication.

              

      

       

      One Officer of the
Company shall sign the Securities on behalf of the Company by manual or
facsimile signature.  The Company’s seal may be (but shall not be
required to be) impressed, affixed, imprinted or reproduced on the Securities
and may be in facsimile form.

       

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

       

      A Security shall
not be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose until authenticated by the manual signature of an authorized
signatory of the Trustee, which signature shall be conclusive evidence that the
Security has been authenticated under this Indenture.

       

      
        
          
          

        

        
          -16-

          
            

          

        

        
          
          

        

      

      The Trustee shall
authenticate (a) for original issue on the Initial Issue Date, Series A
Securities in the aggregate principal amount of $355,000,000, (b) Series B
Securities for original issue, pursuant to any Exchange Offer or Private
Exchange, for a like principal amount of Series A Securities and (c) subject to
Section 3.08 hereof, any amount of Additional Securities specified by the
Company, in each case, upon a written order of the Company signed by one Officer
of the Company.  Such order shall specify (i) the amount of the
Securities to be authenticated and the date of original issue thereof, and (ii)
whether the Securities are Series A Securities or Series B
Securities.  The aggregate principal amount of Securities of any
series outstanding at any time may not exceed the aggregate principal amount of
Securities of such series authorized for issuance by the Company pursuant to one
or more written orders of the Company, except as provided in Section 2.08
hereof.

       

      The Trustee may
appoint an authenticating agent (the “Authenticating
Agent”) reasonably acceptable to the Company to authenticate
Securities.  Unless limited by the terms of such appointment, an
Authenticating Agent may authenticate Securities whenever the Trustee may do
so.  Each reference in this Indenture to authentication by the Trustee
includes authentication by such Authenticating Agent.  An
Authenticating Agent has the same rights as an Agent to deal with the Company,
or an Affiliate of the Company.

       

      The Series A
Securities and the Series B Securities shall be considered collectively to be a
single class for all purposes of this Indenture, including, without limitation,
waivers, amendments, redemptions and offers to purchase.

      and Paying Agent.

              

      

       

      The Company shall
maintain or cause to be maintained an office or agency where Securities may be
presented for registration of transfer or exchange (“Registrar”)
and an office or agency located in the Borough of Manhattan, The City of New
York, State of New York where Securities may be presented for payment (“Paying
Agent”).  The Registrar shall keep a register of the Securities
and of their transfer and exchange (the “Security
Register”).  The Company 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 Agents.

       

      The Company may
enter into an appropriate agency agreement with any Agent not a party to this
Indenture.  The agreement shall implement the provisions of this
Indenture that relate to such Agent.  The Company shall give prompt
written notice to the Trustee of the name and address of any such
Agent.  The Company may change any Paying Agent, Registrar or
co-Registrar without notice to any Holder.  If the Company fails to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act as such.  The Company or any of its Subsidiaries may act as
Paying Agent or Registrar.

initially appoints the Trustee as Registrar and Paying Agent.

       

      The Company
initially appoints The Depository Trust Company (“DTC”)
to act as Depositary with respect to each Global Security.

       

      
        	
                Section
      2.04  

              	
                Paying
      Agent to Hold Money in Trust.

              

      

       

      The Company 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 of, or premium, if
any, or interest on the Securities, whether such money shall have been paid to
it by the Company and will notify the Trustee of any default by the Company 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
and to account for any funds disbursed.  The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any funds disbursed.  Upon payment over to the Trustee and upon
accounting for any funds disbursed, the Paying Agent (if other than the Company
or a Subsidiary of the Company) shall have no further liability for the
money.  If the Company or a Subsidiary of the Company 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.

       

      
        	
                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 Holders and shall otherwise comply
with TIA Section 312(a).  If the Trustee is not the Registrar, the
Company 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 Holders, and the Company shall otherwise
comply with TIA Section 312(a).

       

      
        	
                Section
      2.06

      and Exchange.

              

      

       

      (a) Transfer and
Exchange of Global Securities.

       

      (i) The transfer and
exchange of Global Securities or beneficial interests therein shall be effected
through the Depositary, in accordance with this Indenture (including applicable
restrictions on transfer set forth herein, if any) and the procedures of the
Depositary therefor. A transferor of a beneficial interest in a Global Security
shall deliver to the Registrar a written order given in accordance with the
Depositary’s procedures containing information regarding the participant account
of the Depositary to be credited with a beneficial interest in the Global
Security. The Registrar shall, in accordance with such instructions, instruct
the Depositary to credit to the account of the Person specified in such
instructions a beneficial interest in the Global Security and to debit the
account of the Person making the transfer the beneficial interest in the Global
Security being transferred.

       

      
        
          
          

        

        
          -18-

          
            

          

        

        
          
          

        

      

      (ii) Notwithstanding any
other provisions of this Indenture (other than the provisions set forth in
Section 2.07), a Global Security may not be transferred as a whole except by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary.

       

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

       

      (iii) If a Global
Security is exchanged for Securities in definitive registered form pursuant to
this Section 2.06 or Section 2.07, prior to the consummation of an Exchange
Offer or prior to or in a transfer made pursuant to an effective Shelf
Registration Statement with respect to such Securities, such Securities may be
exchanged only in accordance with such procedures as are substantially
consistent with the provisions of this Section 2.06 (including the certification
and other requirements set forth on the reverse of the Series A Securities
intended to ensure that such transfers comply with Rule 144A or Regulation S, as
the case may be, or are otherwise in compliance with the requirements of the
Securities Act) and such other procedures as may from time to time be adopted by
the Company.

       

      (b) Legend.

       

      (i) Except as permitted
by the following paragraphs (ii), (iii) and (iv), each Security certificate
evidencing the Global Securities (and all Securities issued in exchange therefor
or in substitution thereof) shall bear a legend in substantially the following
form:

       

      [(1)           THIS
SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM
REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933 (THE “SECURITIES
ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN
THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION
THEREFROM.  EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT
THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS
OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A
THEREUNDER.

      (2)           THE
HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS
SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) IN
THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED
INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A
TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) OUTSIDE THE UNITED
STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE
SECURITIES ACT, (III) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE
SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (IV) PURSUANT TO
AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (V) TO AN
INSTITUTIONAL “ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(A)(1), (2), (3) OR
(7) OF REGULATION D UNDER THE SECURITIES ACT) THAT IS ACQUIRING THE SECURITY FOR
ITS OWN ACCOUNT, OR FOR THE ACCOUNT OF SUCH AN INSTITUTIONAL “ACCREDITED
INVESTOR” FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO, OR FOR OFFER OR SALE
IN CONNECTION WITH, ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, IN EACH
OF CASES (I) THROUGH (V) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF
ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT
HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE
RESALE RESTRICTIONS REFERRED TO IN CLAUSE (A) ABOVE.

       

      (3)           AGREES
THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY OR AN INTEREST HEREIN
IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND;
AND

       

      (4)           AGREES
THAT, BEFORE THE HOLDER OFFERS, SELLS OR OTHERWISE TRANSFERS THIS SECURITY, EL
PASO NATURAL GAS COMPANY MAY REQUIRE THE HOLDER OF THIS SECURITY TO DELIVER A
WRITTEN OPINION, CERTIFICATIONS AND/OR OTHER INFORMATION THAT IT REASONABLY
REQUIRES TO CONFIRM THAT SUCH PROPOSED TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE UNITED STATES.

       

      AS USED IN THIS SECURITY, THE TERMS
“OFFSHORE
TRANSACTION,” “U.S.

      (ii) Upon any sale or
transfer of a Transfer Restricted Security (including any Transfer Restricted
Security represented by a Global Security) pursuant to Rule 144 under the
Securities Act, in the case of any Transfer Restricted Security that is
represented by a Global Security, the Registrar shall permit the Holder thereof
to exchange such Transfer Restricted Security for a certificated Security that
does not bear the legend set forth above and rescind any restriction on the
transfer of such Transfer Restricted Security, if the Holder certifies in
writing to the Registrar that its request for such exchange was made in reliance
on Rule 144 (such certification to be in the form set forth on the reverse of

      (iii) After a transfer of
any Series A Securities or Private Exchange Securities during the period of the
effectiveness of and pursuant to a Shelf Registration Statement with respect to
such Series A Securities or Private Exchange Securities, as the case may be, but
nevertheless subject to Section 2.07(a), all requirements pertaining to legends
on such Series A Security or such Private Exchange Security will cease to apply,
the requirements requiring any such Series A Security or such Private Exchange
Security issued to certain Holders be issued in global form will cease to apply,
and a certificated Series A Security or Private Exchange Security without
legends will be available to the transferee of the Holder of such Series A
Securities or Private Exchange Securities upon exchange of such transferring
Holder’s certificated Series A Security or Private Exchange Security or
directions to transfer such Holder’s interest in the Global Security, as
applicable.

       

      (iv) Upon the
consummation of an Exchange Offer with respect to the Series A Securities
pursuant to which Holders of such Series A Securities are offered Series B
Securities in exchange for their Series A Securities, but nevertheless subject
to Section 2.07(a), all requirements pertaining to such Series A Securities that
Series A Securities issued to certain Holders be issued in global form will
cease to apply and certificated Series A Securities with the restricted
securities legend set forth in Section 2.06(b)(i) will be available to Holders
of such Series A Securities that do not exchange their Series A Securities, and
Series B Securities in certificated or global form will be available to Holders
that exchange such Series A Securities in such Exchange
Offer.

       

      (v) Upon the
consummation of a Private Exchange with respect to the Series A Securities
pursuant to which Holders of such Series A Securities are offered Private
Exchange Securities in exchange for their Series A Securities, all requirements
pertaining to such Series A Securities that Series A Securities issued to
certain Holders be issued in global form will still apply, and Private Exchange
Securities in global form with the restricted securities legend set forth in
Section 2.06(b)(i) will be available to Holders that exchange such Series A
Securities in such Private Exchange.

       

      (c) Cancellation
or Adjustment of Global Security. At such time as all beneficial
interests in a Global Security have either been exchanged for certificated
Securities, redeemed, repurchased or canceled, such Global Security shall be
returned to the Depositary for cancellation or retained and canceled by the
Trustee. At any time prior to such cancellation, if any beneficial interest in a
Global Security is exchanged for certificated Securities, redeemed, repurchased
or canceled, the principal amount of Securities represented by such Global
Security shall be reduced and an adjustment shall be made on the books and
records of the Trustee (if it is then the Securities Custodian for such Global
Security) with respect to such Global Security, by the Trustee or the Securities
Custodian, to reflect such reduction.

      (d) Obligations
with Respect to Transfers and Exchanges of Securities.

       

      (i) To permit
registrations of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate certificated Securities and Global Securities at the
Registrar’s or co-Registrar’s request.  No service charge shall be
made for any registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any transfer tax, assessments, or similar
governmental charge payable in connection therewith (other than any such
transfer taxes, assessments or similar governmental charge payable upon exchange
or transfer pursuant to Section 8.05 and Section 9.06).

       

      (ii) The Registrar or
co-Registrar shall not be required to register the transfer of or exchange of
(1) any certificated Security selected for redemption in whole or in part
pursuant to Article IX, except the unredeemed portion of any certificated
Security being redeemed in part, or (2) any Security for a period beginning 15
Business Days before the mailing of a notice of an offer to repurchase or redeem
Securities or 15 Business Days before an interest payment
date.

       

      (iii) Prior to the due
presentation for registration of transfer of any Security, the Company, the
Trustee, the Paying Agent, the Registrar or any co-Registrar may deem and treat
the Person in whose name a Security is registered as the absolute owner of such
Security for the purpose of receiving payment of principal of, premium, if any,
and interest and Liquidated Damages, if any, on such Security and for all other
purposes whatsoever, whether or not such Security is overdue, and none of the
Company, the Trustee, the Paying Agent, the Registrar or any co-Registrar shall
be affected by notice to the contrary.

       

      (iv) All Securities
issued upon any transfer or exchange pursuant to the terms of this Indenture
shall evidence the same debt and shall be entitled to the same benefits under
this Indenture as the Securities surrendered upon such transfer or
exchange.

       

      (e) No
Obligation of the Trustee.

       

      (i) The Trustee shall
have no responsibility or obligation to any beneficial owner of a Global
Security, any Agent Member or other Person with respect to the accuracy of the
records of the Depositary or its nominee or of any participant or member
thereof, with respect to any ownership interest in the Securities or with
respect to the delivery to any participant, member, beneficial owner or other
Person (other than the Depositary) of any notice (including any notice of
redemption) or the payment of any amount, under or with respect to such
Securities. All notices and communications to be given to the Holders and all
payments to be made to Holders under the Securities shall be given or made only
to or upon the order of the registered Holders (which shall be the Depositary or
its nominee in the case of a Global Security). The rights of beneficial owners
in any Global Security shall be exercised only through the Depositary subject to
the applicable rules and procedures of the Depositary. The Trustee may rely
conclusively and shall be fully protected in relying upon information furnished
by the Depositary with respect to its members, participants and any beneficial
owners.

      (ii) 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 Security
(including any transfers between or among Agent Members or beneficial owners in
any Global Security) other than to require delivery of such certificates 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.

      2.07  

              	
                Certificated
      Securities.

              

      

       

      (a) A Global Security
deposited with the Depositary or with the Trustee as custodian for the
Depositary pursuant to Section 2.01 shall be transferred to the beneficial
owners thereof in the form of certificated Securities in an aggregate principal
amount equal to the principal amount of such Global Security, in exchange for
such Global Security, only if such transfer complies with Section 2.06 and (i)
the Depositary notifies the Company that it is unwilling or unable to continue
as Depositary for such Global Security or if at any time such Depositary ceases
to be a “clearing agency” registered under the Exchange Act and a successor
depositary is not appointed by the Company within 90 days of such notice, or
(ii) the Company, in its sole discretion, notifies the Trustee in writing that
it elects to cause the issuance of certificated Securities under this
Indenture.

       

      (b) Any Global Security
that is transferred to the beneficial owners thereof pursuant to this Section
2.07 shall be surrendered by the Depositary to the Trustee at its office located
in the Borough of Manhattan, The City of New York, to be so transferred, in
whole or from time to time in part, without charge, and the Trustee shall
authenticate and deliver, upon such transfer of each portion of such Global
Security, an equal aggregate principal amount of certificated Securities of
authorized denominations. Any portion of a Global Security transferred pursuant
to this Section shall be executed, authenticated and delivered only in
denominations of $1,000 and any integral multiple thereof and registered in such
names as the Depositary shall direct. Any certificated Series A Security
delivered in exchange for an interest in the Global Security shall, except as
otherwise provided by Section 2.06(d), bear the restricted securities legend set
forth in Section 2.06(b).

      (c) Subject to the
provisions of Section 2.06(b), the registered Holder of a Global Security may
grant proxies and otherwise authorize any Person, including Agent Members and
Persons that may hold interests through Agent Members, to take any action which
a Holder is entitled to take under this Indenture or the
Securities.

       

      (d) If either of the
events specified in Section 2.07(a) occurs, the Company shall promptly make
available to the Trustee a reasonable supply of certificated Securities in
definitive, fully registered form without interest coupons.

       

      (e) If a certificated
Security issued pursuant to this Section 2.07 is exchanged for another
certificated Security prior to the consummation of an Exchange Offer or prior to
or in a transfer made pursuant to an effective Shelf Registration Statement with
respect to such Securities, such Securities may be exchanged only in accordance
with such procedures as are substantially consistent with the provisions of (i)
Section 2.06(a)(iii) (including the certification and other requirements set
forth on the reverse of the Series A Securities intended to ensure that such
transfers comply with Rule 144A or Regulation S, as the case may be, or are
otherwise in compliance with the requirements of the Securities Act) and such
other procedures as may from time to time be adopted by the Company and (ii)
Section 2.06(b).

       

      
        	
                Section
      2.08  

              	
                Replacement
      Securities.

              

      

       

      If any mutilated
Security is surrendered to the Trustee, or the Company and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any
Security, the Company shall issue and the Trustee shall authenticate
a  replacement Security, but only if the Trustee’s requirements are
met.  Such Holder must furnish an indemnity bond that is sufficient in
the judgment of the Trustee and the Company to protect the Company, the Trustee,
any Agent or any authenticating agent from any loss which any of them may suffer
if a Security is replaced.  The Company and the Trustee may charge for
their expenses in replacing a Security.  If, after the delivery of
such replacement Security, a bona fide purchaser of the original Security in
lieu of which such replacement Security was issued presents for payment or
registration such original Security, the Trustee shall be entitled to recover
such replacement Security from the Person to whom it was delivered or any Person
taking therefrom, except a bona fide purchaser, and shall be entitled to recover
upon the security or indemnity provided therefor to the extent of any loss,
damage, cost or expense incurred by the Trustee or the Company in connection
therewith.

       

      Every replacement
Security is an additional obligation of the Company.

      2.09  

              	
                Outstanding
      Securities.

              

      

       

      The Securities
outstanding at any time are all the Securities authenticated by the Trustee
except for those canceled by it, those delivered to it for cancellation, those
reductions in the interest in a Global Security effected by the Trustee
hereunder and those described in this Section 2.09 as not outstanding; provided,
however,
that in determining whether the holders of the requisite principal amount of
outstanding Securities are present at a meeting of holders of Securities for
quorum purposes or have consented to or voted in favor of any request, demand,
authorization, direction, notice, consent, waiver, amendment or modification
hereunder, Securities held for the account of the Company, any of its
Subsidiaries or any of their respective Affiliates shall be disregarded and
deemed not to be outstanding, except that in determining whether the Trustee
shall be protected in making such a determination or relying upon any such
quorum, consent or vote, only Securities which a Responsible Officer of the
Trustee actually knows to be so owned shall be so disregarded.

      If a Security is
replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Security is held by
a bona fide purchaser.

       

      A Security with
respect to which the Company has effected defeasance or covenant defeasance
ceases to be outstanding except to the extent provided in Sections 7.02 and
7.03.

       

      If the principal
amount of any Security is considered paid under Section 3.01 hereof, it ceases
to be outstanding and interest on it ceases to accrue.

       

      Except as set forth
in Section 2.10 hereof, a Security does not cease to be outstanding because the
Company or any of its Affiliates holds the Security.

       

      
        	
                Section
      2.10  

              	
                Treasury
      Securities.

              

      

       

      In determining
whether the Holders of the required principal amount of Securities have
concurred in any direction, waiver or consent, Securities owned by the Company
or any of its Affiliates shall be disregarded, except that for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities which a Responsible Officer of the
Trustee actually knows are so owned shall be so disregarded.

      Securities.

              

      

       

      Until definitive
Securities are ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities, but may have variations that the Company
considers appropriate for temporary Securities.  Without unreasonable
delay, the Company shall prepare and the Trustee shall authenticate definitive
Securities in exchange for temporary Securities.  Until so exchanged,
the temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

                Cancellation.

              

      

       

      The Company at any
time may deliver Securities to the Trustee for cancellation.  The
Registrar and the Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange or
payment.  The Trustee shall cancel all Securities surrendered for
registration of transfer, exchange, payment, replacement or
cancellation.  All canceled Securities held by the Trustee shall be
disposed of in accordance with the usual disposal procedures of the
Trustee.  The Company may not issue new Securities to replace
Securities that have been paid or that have been delivered to the Trustee for
cancellation.

      Interest.

              

      

       

      If the Company
defaults in a payment of interest on the Securities, it shall pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest on the
defaulted interest, in each case at the rate provided in the Securities and in
Section 3.01 hereof.  The Company may pay the defaulted interest to
the Persons who are Holders on a subsequent special record date.  At
least 15 days before any special record date, the Company (or the Trustee, in
the name of and at the expense of the Company) shall mail to Holders a notice
that states the special record date, the related payment date and the amount of
such interest to be paid.

      The Company, the
Trustee, any Agent and any authenticating agent may treat the Person in whose
name any Security is registered as the owner of such Security for the purpose of
receiving payments of principal of, or premium, if any, or interest on such
Security and for all other purposes.  None of the Company, the
Trustee, any Agent or any authenticating agent shall be affected by any notice
to the contrary.

      The Company in
issuing the Securities may use “CUSIP” numbers (if then generally in use), and,
if 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 Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities,  and any such
redemption shall not be affected by any defect in or omission of such
numbers.  The Company shall promptly notify the Trustee of any change
in the “CUSIP” numbers.

      The Company shall
maintain, in the Borough of Manhattan, The City of New York, an office or agency
(which may be an office of the Trustee, the Registrar or the Paying Agent) where
Securities may be presented for registration of transfer or exchange, where
Securities may be presented for payment and where notices and demands to or upon
the Company in respect of the Securities and this Indenture may be
served.  Unless otherwise designated by the Company by written notice
to the Trustee, such office or agency shall be the principal office of the
Trustee in the Borough of Manhattan, The City of New York, which, on the date
hereof, is located at the address set forth in Section 10.02
hereof.  The Company 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 Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee.

       

      The Company may
also from time to time designate one or more other offices or agencies where the
Securities 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 Company
of its obligation to maintain an office or agency in the Borough of Manhattan,
The City of New York for such purposes.  The Company shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.  The
Company hereby designates the Corporate Trust Office of the Trustee as one such
office or agency of the Company in accordance with Section 2.03
hereof.

that the Company may not be required to remain subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, the Company shall file

Holder requesting copies of, such annual and quarterly reports and such

otherwise have been required) to file such reports, information and

availability (unless the SEC will not accept such filing). In addition, the
Company shall furnish to the Holders and to prospective investors, upon the

to secure all or a portion of the purchase price for such property or assets or
Indebtedness incurred to finance such purchase price, whether such Indebtedness
was incurred prior to, at the time of or within one year of such
acquisition;

       

      (c)  any Lien upon
any property or assets existing thereon at the time of the acquisition thereof

natural resources;

       

      (i)  any Lien in
favor of the Company or any Restricted Subsidiary;

       

      (j)  any Lien
created or assumed by the Company or any Restricted  Subsidiary in
connection with the issuance of Indebtedness the interest on which is excludable
from gross income of the holder of such Indebtedness pursuant to the Internal
Revenue Code of 1986, as amended, or any successor statute, for the purpose of
financing, in whole or in part, the acquisition or construction of property or
assets to be used by the Company or any Restricted

not exceed the greater of the principal amount of Indebtedness so secured at the
time of such Refinancing and the original principal amount of Indebtedness so
secured (plus in each case the aggregate amount of premiums, other payments,
costs and expenses required to be paid or incurred in connection with such
Refinancing); provided,
further, however, that such Refinancing shall be limited to all or a part

      Notwithstanding the
foregoing provisions of this Section, the Company may, and may permit any
Restricted Subsidiary to, create, assume, incur or suffer to exist any other
Lien upon any Principal Property to secure any Indebtedness of the Company or
any other Person (other than the Securities) that is not excepted by clauses (a)
through (n), inclusive, of this Section without securing the Securities issued
hereunder; provided
that the aggregate principal amount of all Indebtedness then outstanding secured
by such other Lien and all other similar Liens, together with all net sale
proceeds from Sale-Leaseback Transactions (excluding Sale-Leaseback Transactions
permitted by clauses (a) through (d), inclusive, of Section 3.06), does not
exceed 15% of Consolidated Net Tangible Assets.

Transaction occurs within one year from the date of acquisition of the Principal
Property subject thereto or the date of the completion of construction or
commencement of full operations on such Principal Property, whichever is
later;

      (b)  the
Sale-Leaseback Transaction involves a lease for a period, including renewals, of
not more than three years;

       

      (c)  the Company
or such Restricted Subsidiary would be entitled to incur Indebtedness secured by
a Lien on the Principal Property subject thereto in a principal amount equal to

      (d) the Company or such
Restricted Subsidiary, within a one-year period after such Sale-Leaseback

Subsidiary, or (ii) investment in another Principal
Property.

       

                 Notwithstanding
the foregoing provisions of this Section, the Company may, and may permit any

that the net sale proceeds from such other Sale-Leaseback Transaction, together
with the aggregate principal amount of then outstanding Indebtedness (other than
the Securities) secured by Liens upon Principal Properties not excepted by
clauses (a) through (n), inclusive, of Section 3.05, do not exceed 15% of
Consolidated Net Tangible Assets.

      (a) The Company shall
not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly, participate in El Paso’s and its Subsidiaries’ cash management
program if any default occurs or exists under any bond, debenture, note or other
evidence of Debt for money borrowed or under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Debt for money borrowed, in each case, by El Paso or any of its
Subsidiaries (or the payment of which is guaranteed by El Paso or any of its
Subsidiaries) whether such Debt or guarantee now exists, or is created after the
date of this Indenture, if such default:

       

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

       

      (ii) results in the
acceleration (without cure or revocation within five Business Days) of Debt of
El Paso prior to its express maturity

       

      and, in each case,
the principal amount of any such Debt of El Paso, together with the principal
amount of any other such Debt of El Paso under which there has been a Payment
Default or the maturity of which has been so accelerated, aggregates $50 million
or more, until such acceleration has been cured or revoked or such payment of
such Debt of El Paso has been made in full.

       

      (b) This Section 3.09
shall be of no force or effect from and after the time the Securities are first
rated at least Baa3 by Moody’s and at least BBB- by Standard &

benefit of, any of the Company’s Affiliates (an “Affiliate
Transaction”), unless:

       

      (i) the terms of such
Affiliate Transaction are:

       

      (1) set forth in
writing and

       

      (2) no less favorable
to the Company or such Restricted Subsidiary, as the case may be, than those
that could be obtained in a comparable arm’s-length transaction with a Person
that is not one of the Company’s Affiliates or, if there is no such comparable
transaction, on terms that are fair and reasonable to the Company or such
Restricted Subsidiary,

      (ii) if such Affiliate
Transaction involves aggregate payments or value in excess of $25 million, the
Company’s Board of Directors approves such Affiliate Transaction and, in its
good faith judgment, believes that such Affiliate Transaction complies with
clause (i)(2) of this Section 3.10(a), and

       

      (iii) if such Affiliate
Transaction involves aggregate payments or value in excess of $100 million, the
Company shall obtain a written opinion from an Independent Financial Advisor to
the effect that the consideration to be paid or received in connection with such
Affiliate Transaction is fair, from a financial point of view, to the Company or
the applicable Restricted Subsidiary, as the case may be.

       

      (b) Notwithstanding the
preceding limitation, the following shall not be Affiliate
Transactions:

modification of the Western Energy Settlement on terms that are fair and
reasonable to the Company; and

paying all or any portion of the principal of, premium, if any, Liquidated

contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture; and (to the

benefit or advantage of any such law, and covenants that it shall not hinder,
delay or impede the execution of any power herein granted to the Trustee, but

      of Default.

              

      

       

      “Event
of Default”, wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental
body):

       

      (a) default in the
payment of any interest or Liquidated Damages, if any, upon any Security of that
series when it becomes due and payable, and continuance of such default for a
period of 30 days; or

       

      (b)  default in
the payment of the principal of (or premium, if any, on) any Security of that
series at its Maturity; or

       

      (c)  default in
the performance, or breach, of any other term, covenant or warranty of the
Company in this Indenture (other than a term, covenant or warranty a default in
whose performance or whose breach is elsewhere in this Section specifically
dealt with or which has expressly been included in this Indenture solely for the
benefit of a series of Securities other than that series), and continuance of
such default or breach for a period of 60 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
outstanding Securities of that series a written notice specifying such default
or breach and requiring it to be remedied and stating that such notice is a
"Notice of Default" hereunder; or

      (d) the Company
pursuant to or within the meaning of any Bankruptcy Law (i) commences a
voluntary case, (ii) consents to the entry of any order for relief against it in
an involuntary case, (iii) consents to the appointment of a Custodian of it or
for all or substantially all of its property, or (iv) makes a general assignment
for the benefit of its creditors;

       

      (e)  a court of
competent jurisdiction enters an order or decree under any Bankruptcy Law that
(i) is for relief against the Company in an involuntary case, (ii) appoints a
Custodian of the Company or for all or substantially all of its property, or
(iii) orders the liquidation of the Company; and the order or decree remains
unstayed and in effect for 90 days; or

       

      (f) there shall be a
default under any bond, debenture, note or other evidence of debt for money
borrowed or under any mortgage, indenture or other instrument under which there
may be issued or by which there may be secured or evidenced any debt for money
borrowed by the Company or any of its Restricted Subsidiaries or under any
guarantee of payment by the Company or any of its Restricted Subsidiaries of
debt for money borrowed (other than a default under any debt of El Paso or one
or more Subsidiaries of El Paso (other than the Company or any of its Restricted
Subsidiaries) guaranteed by one or more of the Company’s Restricted
Subsidiaries), whether such debt or guarantee now exists or shall hereafter be
created, and the effect of such default is to result in such debt becoming due
prior to its stated maturity; provided,
however, that no Event of Default under this clause (f) shall exist if
all such defaults do not relate to such debt or such guarantees with an
aggregate principal amount in excess of $25 million at the time outstanding; and
provided
further, that if such default under such bond, debenture, note or other
evidence of debt for borrowed money or any mortgage, indenture or other
instrument shall be cured by the Company or its Restricted Subsidiary, or be
waived by the holders of such debt, in each case as may be permitted by such
bond, debenture, note or other evidence of debt for borrowed money or any
mortgage, indenture or other instrument, then the Event of Default under this
clause (f) by reason of such default shall be deemed likewise to have been
thereupon cured or waived.

       

      Subject to the
provisions of Section 6.01 and Section 6.02, the Trustee shall not be charged
with knowledge of an Event of Default unless written notice thereof shall have
been given to a Responsible Officer at the Corporate Trust Office of the Trustee
by the Company, the Paying Agent, any Holder or an agent of any
Holder.

                Acceleration.

              

      

       

      If an Event of
Default with respect to the Securities of a series (other than an Event of
Default specified in clause (d) or (e) of Section 5.01 hereof with respect to
the Company) occurs and is continuing, the Trustee may by notice to the Company,
or the Holders of at least 25% in principal amount of the then outstanding
Securities of that series may, by notice to the Company and the Trustee, and the
Trustee shall, upon the request of such Holders, declare the principal of,
premium, if any, on, accrued and unpaid interest on, and Liquidated Damages, if
any, on all then outstanding Securities of that series (if not then due and
payable) to be due and payable, and upon any such declaration the same shall
become and be immediately due and payable.  If an Event of Default
specified in clause (d) or (e) of Section 5.01 hereof with respect to the
Company occurs, the principal of, premium, if any, on, accrued and unpaid
interest on, and Liquidated Damages, if any, on all Securities then outstanding
shall ipso
facto become and be immediately due and payable without any declaration,
notice or other act on the part of the Trustee or any Holder.

      At any time after
such a declaration of acceleration with respect to the Securities of a series
has been made and before a judgment for payment of the money due has been
obtained by the Trustee as hereinafter in this Article V, the Holders of a
majority in principal amount of the outstanding Securities of that series, by
written notice to the Company and the Trustee, may rescind and annul such
acceleration and its consequences if:

       

              (a) all existing Events
of Default, other than the non-payment of the principal of the Securities of a
series which has become due solely by such declaration of acceleration, have
been cured or waived;

       

              (b) to the extent the
payment of such interest is lawful, interest on overdue installments of interest
and overdue principal, which has become due otherwise than by such declaration
of acceleration, has been paid; and

       

      (c) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction.

                Other
      Remedies.

              

      

       

      If an Event of
Default occurs  and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal of, or premium, if any,
Liquidated Damages, if any, or interest on the Securities of the affected series
or to enforce the performance of any provision of such Securities, this
Indenture or any Registration Rights Agreement.

       

      The Trustee may
maintain a proceeding even if it does not possess any of the Securities or does
not produce any of them in the proceeding.  A delay or omission by the
Trustee or any Holder 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.

      of Existing Defaults.

              

      

       

      Subject to Section
5.07 and Section 8.02, the Holders of a majority in principal amount of the
outstanding Securities of the affected series by notice to the Trustee may waive
an existing Default or Event of Default and its consequences (including waivers
obtained in connection with a tender offer or exchange offer for such Securities
or a solicitation of consents in respect of such Securities, provided
that in each case such offer or solicitation is made to all Holders
of  such Securities then outstanding on equal terms), except (a) a
continuing Default or Event of Default in the payment of the principal of, or
premium, if any, or Liquidated Damages, if any, or interest on such Securities
or (b) a continuing Default in respect of a provision that under Section 8.02
hereof cannot be amended without the consent of each Holder
affected.  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.

      The Holders of a
majority in principal amount of the Securities of the affected series then
outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on it hereunder.  However, the Trustee may refuse to follow
any direction that conflicts with applicable law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of other Holders, or
that may involve the Trustee in personal liability; provided,
however,
that the Trustee may take any other action deemed proper by the Trustee that is
not inconsistent with such direction.  Prior to taking any action
hereunder, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

      Subject to Section
5.07 hereof, a Holder may pursue a remedy with respect to this Indenture or the
Securities only if:

       

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

       

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

       

      (c) such Holder or
Holders offer 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 of indemnity; and

       

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

       

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

      Notwithstanding any
other provision of this Indenture, the right of any Holder of a Security to
receive payment of principal of, and premium, if any, and interest on the
Security, on or after the respective due dates expressed in the Security, or to
bring suit for the enforcement of any such payment on or after such respective
dates, is absolute and unconditional and shall not be impaired or affected
without the consent of such Holder.

Default specified in clause (a) or (b) of Section 5.01 hereof occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the amount of principal and
premium, if any, and interest (and Liquidated Damages, if any) remaining unpaid
on the Securities of the affected series, and interest on overdue principal,
premium, if any, and Liquidated Damages, if any and, to the extent lawful,
interest on overdue interest (and Liquidated Damages, if any), and such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of

      5.09  

              	
                Trustee
      May File Proofs of Claim.

              

      

       

      The Trustee is
authorized to file such proofs of claim and other papers or documents and to
take such actions, including participating as a member, voting or otherwise, of
any committee of creditors, 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 allowed in any judicial proceedings relative to the Company or its
creditors or properties 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 6.07 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 6.07 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 which 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
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

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

       

      First:  to
the Trustee for amounts due under Section 6.07 hereof;

       

      Second:  to
Holders for amounts due and unpaid on the Securities of the affected series for
principal, premium, if any, Liquidated Damages, if any, and interest ratably,
without preference or priority of any kind, according to the amounts due and
payable on such Securities for principal, premium, if any, Liquidated Damages,
if any, and interest, respectively; and

       

      Third:  to
the Company.

       

      The Trustee, upon
prior written notice to the Company, may fix a record date and payment date for
any payment to Holders pursuant to this Article V.

      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 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 5.07 hereof, or a suit by a Holder or Holders of more than 10% in
principal amount of the Securities of the affected series then
outstanding.

      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 such exercise, as a prudent Person 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 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

       

      
        
          
          

        

        
          -44-

          
            

          

        

        
          
          

        

      

      (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, with respect to certificates
or opinions specifically required by any provision hereof to be furnished to it,
the Trustee shall examine such certificates and opinions to determine whether or
not, on their face, they appear to conform substantially to the requirements of
this Indenture.

       

      (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

pertinent facts; and

       

      (iii) the Trustee shall
not be liable with respect to any action it takes or omits to take in good faith
in accordance with a direction received by it pursuant to Section 5.05
hereof.

       

      (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

this Indenture shall require the Trustee to expend or risk its own funds or
incur any liability.

       

      (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 Company.  Money held in trust by the Trustee
need not be segregated from other funds except to the extent required by
law.  All money received by the Trustee shall, until applied as herein
provided, be held in trust for the payment of the principal of,
and  premium if any, and Liquidated Damages, if any, and interest on
the Securities.

       

      
        	
                Section
      6.02  

              	
                Rights
      of Trustee.

              

      

       

      (a) The Trustee may
rely conclusively on any document (whether in its original or facsimile form)
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, 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 own selection and the advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

      (c) The Trustee may act
through agents or attorneys and shall not be responsible for the 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 which it
believes to be authorized or within its rights or powers conferred upon it by
this Indenture.

       

      (e) Unless otherwise
specifically provided in this Indenture, any demand, request, direction or
notice from the Company shall be sufficient if signed by an Officer of the
Company.

required to give any bond or surety with respect to the performance of its
duties or the exercise of its powers under this Indenture.

       

      (g) 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
and be enforceable by the Trustee in each of its capacities hereunder and shall
extend to the Trustee’s officers, directors, agents and
employees.  Such immunities and protections and right to indemnity,
together with the Trustee’s right to compensation, shall survive the Trustee’s
resignation or removal, the discharge of this Indenture and final payment of the
Securities.

       

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

       

      (i) Except for
information provided by the Trustee concerning the Trustee, the Trustee shall
have no responsibility for any information in any offering memorandum or other
disclosure material distributed with respect to the Securities, and the Trustee
shall have no responsibility for compliance with any state or federal securities
laws in connection with the Securities.

       

      (j) The Trustee may
request that the Company deliver an Officers’ Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take
specified actions pursuant to this Indenture, which Officers’ Certificate may be
signed by any person authorized to sign an Officers’ Certificate, including any
person specified as so authorized in any such certificate previously delivered
and not superseded.

       

      (k) 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 pursuant to
this Indenture, unless such Holders shall have offered to the Trustee security
or indemnity satisfactory to the Trustee against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction.

                Individual
      Rights of Trustee.

              

      

       

      The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or any of its Affiliates with the same
rights it would have if it were not Trustee.  Any Agent may do the
same with like rights.  However, the Trustee is subject to Section
6.10 and Section 6.11 hereof.

       

      
        	
                Section
      6.04  

              	
                Trustee’s
      Disclaimer.

              

      

       

      The Trustee makes
no representation as to the validity or adequacy of this Indenture or the
Securities, it shall not be accountable for the Company’s use of the proceeds
from the Securities or any money paid to the Company or upon the Company’s
direction under any provision hereof, 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 Securities other than its certificate of authentication.

                Notice
      of Defaults.

              

      

       

      If a Default or
Event of Default occurs and is continuing and it is actually known to a
Responsible Officer of the Trustee, the Trustee shall mail to Holders 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, or premium, if any, Liquidated Damages, if any, or
interest on any Security, 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 Holders.

       

      
        	
                Section
      6.06  

              	
                Reports
      by Trustee to
Holders.

              

      

       

      On or before July
15 of each year, beginning with July 15, 2004, the Trustee shall mail to Holders
a brief report dated as of a date convenient to the Trustee no more than 60 nor
less than 45 days prior thereto, that complies with TIA Section 313(a); provided,
however,
that 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).  The Trustee shall also transmit by mail all reports as
required by TIA Sections 313(c) and 313(d).

       

      A copy of each
report at the time of its mailing to Holders shall be filed with the SEC and
each securities exchange, if any, on which the Securities are
listed.  The Company shall promptly notify the Trustee if and when the
Securities are listed on any stock exchange or delisted therefrom.

       

      
        
          
          

        

        
          -47-

          
            

          

        

        
          
          

        

      

      
        	
                Section
      6.07  

              	
                Compensation
      and Indemnity.

              

      

       

      The Company agrees
to pay to the Trustee from time to time such compensation as agreed to by the
Company and the Trustee, for its acceptance of this Indenture and its services
hereunder.  The Trustee’s compensation shall not be limited by any law
on compensation of a trustee of an express trust.  Subject to the
further provisions of this Section 6.07, the Company agrees to reimburse the
Trustee upon request for all reasonable disbursements, advances and expenses
incurred by it.  Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee’s agents and
counsel.

       

      The Company agrees
to fully indemnify the Trustee or any predecessor Trustee and their agents for
and to hold them harmless against any and all loss, liability, damage, claims,
or expense (including taxes, other than taxes based upon, measured by or
determined by the income of the Trustee) incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture, including the reasonable costs and expenses of defending itself
against any claim (whether asserted by the Company, any Holder or any other
Person), except as set forth in the next paragraph.  The Trustee shall
notify the Company promptly of any claim for which it may seek
indemnity.  The Company shall defend the claim and the Trustee shall
cooperate in the defense.  The Trustee may have separate counsel, and
the Company shall pay the reasonable fees and expenses of such
counsel.  The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld.

       

      The Company shall
not be obligated to reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through its own negligence, willful misconduct
or bad faith.

       

      To secure the
payment obligations of the Company in this Section 6.07, the Trustee shall have
a lien prior to the Securities on all money or property held or collected by the
Trustee, except that held in trust to pay principal of, and premium, if any, and
interest and Liquidated Damages, if any, on the Securities.  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 5.01(d) or Section 5.01(e) hereof occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

       

      The provisions of
this Section 6.07 shall survive the termination of this Indenture.

       

      
        	
                Section
      6.08  

              	
                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 6.08.

       

      The Trustee may
resign and be discharged from the trust hereby created by so notifying the
Company.  The Holders of a majority in principal amount of the then
outstanding Securities may remove the Trustee by so notifying the Trustee and
the Company.  The Company may remove the Trustee if:

       

      
        
          
          

        

        
          -48-

          
            

          

        

        
          
          

        

      

      (a) the Trustee fails
to comply with Section 6.10 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
otherwise 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 Company 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 Securities then outstanding
may appoint a successor Trustee to replace the successor Trustee appointed by
the Company.

       

      If a successor
Trustee does not take office within 30 days after the retiring Trustee resigns
or is removed, the retiring Trustee, the Company or the Holders of at least 10%
in principal amount of the Securities then outstanding may petition (at the
expense of the Company) any court of competent jurisdiction at the expense of
the Company for the appointment of a successor Trustee.

       

      If the Trustee
fails to comply with Section 6.10 hereof, any Holder 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 Company. 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.  The
retiring Trustee shall promptly transfer all property held by it as Trustee to
the successor Trustee, subject to the lien provided for in Section 6.07
hereof.  Notwithstanding replacement of the Trustee pursuant to this
Section 6.08 hereof, the obligations of the Company under Section 6.07 hereof
shall continue for the benefit of the retiring Trustee.

      Trustee by Merger,
etc.

              

      

       

      Subject to Section
6.10 hereof, 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.

       

      In case any
Securities shall have been authenticated, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

      There shall at all
times be a Trustee hereunder which shall be a corporation organized and doing
business under the laws of the United States, any state thereof or the District
of Columbia and authorized under such laws to exercise corporate trust power,
shall be subject to supervision or examination by federal or state (or the
District of Columbia) authority and shall have, or be a Subsidiary of a bank or
bank holding company having, 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 Sections
310(a)(1), 310(a)(2) and 310(a)(5).  The Trustee is subject to and
shall comply with the provisions of TIA Section 310(b) during the period of time
required by this Indenture.  Nothing in this Indenture shall prevent
the Trustee from filing with the SEC the application referred to in the
penultimate paragraph of TIA Section 310(b).

INDENTURE; DEFEASANCE

       

      
        	
                Section
      7.01  

              	
                Discharge
      of Indenture.

              

      

       

      Upon the request of
the Company, this Indenture will cease to be of further effect and the Trustee,
at the expense of the Company, will execute proper instruments acknowledging
satisfaction and discharge of the Securities and this Indenture
when:

       

      (a) either:

       

      (i) all the Securities
theretofore authenticated and delivered (other than destroyed, lost or stolen
Securities that have been replaced or paid and Securities that have been subject
to defeasance pursuant to Section 7.02 or 7.03) have been delivered to the
Trustee for cancellation; or

       

      (ii) all Securities not
theretofore delivered to the Trustee for cancellation:

      (1) have become due and
payable by the mailing of a notice of redemption or
otherwise;

       

      (2) will become due and
payable within one year; or

       

      (3) are to be called
for redemption within 12 months under arrangements reasonably satisfactory to
the Trustee for the giving of notice of redemption by the Trustee in the name,
and at the reasonable expense, of the Company;

       

      1. and the Company has
irrevocably deposited or caused to be deposited with the Trustee funds in trust
for the purpose in an amount sufficient to pay and discharge, the entire Debt on
the Securities, including, if any, Liquidated Damages with respect to the
Securities, not theretofore delivered to the Trustee for cancellation, for
principal (and premium, if any) and interest on the Securities to the date of
such deposit (in case of Securities that have become due and payable) or to the
Stated Maturity or redemption date, as the case may be;

       

      (b) the Company has
paid or caused to be paid all sums payable under this Indenture by the Company;
and

       

      (c) the Company has
delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel,
each stating that all conditions precedent provided in this Indenture relating
to the satisfaction and discharge of the Securities and this Indenture have been
complied with.

       

      After such
delivery, the Trustee upon request of the Company shall acknowledge in writing
the discharge of the Company’s obligations under the Securities and this
Indenture except for those surviving obligations specified below.

       

      Notwithstanding the
satisfaction and discharge of this Indenture, the obligations of the Company in
Sections 6.07, 7.05 and 7.06 shall survive such satisfaction and
discharge.

       

      
        	
                Section
      7.02  

              	
                Legal
      Defeasance.

              

      

       

      The Company may, at
its option and at any time, elect to have its obligations discharged with
respect to the outstanding Securities on a date the conditions set forth in
Section 7.04 are satisfied (hereinafter, “Legal
Defeasance”).  For this purpose, such Legal Defeasance means
that the Company will be deemed to have paid and discharged the entire Debt
represented by the outstanding Securities and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee, at the expense of the Company, shall, subject to
Section 7.06, execute instruments in form and substance reasonably satisfactory
to the Trustee and Company acknowledging the same), except for the following
which shall survive until otherwise terminated or discharged
hereunder:  (a) the rights of Holders of outstanding Securities
to receive solely from the trust funds described in Section 7.04 and as more
fully set forth in such Section, payments in respect of the principal of,
premium, if any, and interest on such Securities when such payments are due,
(b) the Company’s obligations with respect to such Securities under
Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2,07, 2.08, 2.11 and 3.02, (c) the
rights, powers, trusts, duties, and immunities of the Trustee hereunder
(including claims of, or payments to, the Trustee under or pursuant to Section
6.07) and the Company’s obligations in connection therewith and (d) this
Article VII.

      Subject to
compliance with this Article VII, the Company may exercise its option under
this Section 7.02 with respect to the Securities notwithstanding the prior
exercise of its option under Section 7.03 below with respect to the
Securities.

       

      
        	
                Section
      7.03  

              	
                Covenant
      Defeasance.

              

      

       

      The Company may, at
its option and at any time, elect to have its obligations under
Sections 3.05, 3.06, 3.07, 3.08, 3.09 and 3.10 released with respect to the
outstanding Securities on a date the conditions set forth in Section 7.04 are
satisfied (hereinafter, “Covenant
Defeasance”).  For this purpose, Covenant Defeasance means
that, with respect to the outstanding Securities, the Company may fail 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 5.01, but, except as specified above, the remainder of this
Indenture and such Securities shall be unaffected thereby.  In
addition, upon the Company’s exercise of the option in this Section 7.03,
subject to the satisfaction of the conditions set forth in Section 7.04,
Sections 5.01(c), (d) and (e) shall not constitute Events of
Default.

       

      Notwithstanding any
discharge or release of any obligations under this Indenture pursuant to Section
7.02 or this Section 7.03, the Company’s obligations in Sections 2.03, 2.05,
2.06, 2.07, 2.08, 6.07, 7.05, 7.06 and 7.08 shall survive until such time as the
Securities have been paid in full.  Thereafter, the Company’s
obligations in Sections 6.07, 7.05 and 7.08 shall survive.

       

      
        	
                Section
      7.04  

              	
                Conditions
      to Legal Defeasance or Covenant
Defeasance.

              

      

       

      The following shall
be the conditions to application of Section 7.02 or Section 7.03 to the
outstanding Securities:

       

      (a) (i)           the
Company has irrevocably deposited or caused to be deposited in trust for the
benefit of the Holders with the Trustee or a Paying Agent or a trustee
satisfactory to the Trustee and the Company, under the terms of an irrevocable
trust agreement in form and substance satisfactory to the Trustee and any such
Paying Agent, (x) money in an amount sufficient, or (y) U.S.
Government Obligations that shall be payable as to principal and interest in
such amounts and at such times as are sufficient, in the opinion of a nationally
recognized firm of independent public accountants or Independent Financial
Advisors expressed in a written certification thereof delivered to the Trustee
(without consideration of any reinvestment of such interest), or (z) a
combination thereof in an amount, sufficient to pay the principal of (and
premium, if any, on) and interest, if any, to Stated Maturity (or redemption) on
such Securities, on the scheduled due dates therefor, (ii) the trustee of
the irrevocable trust has been irrevocably instructed to pay such money or the
proceeds of such U.S. Government Obligations to the Trustee and (iii) the
Trustee or Paying Agent shall have been irrevocably instructed in writing to
apply the deposited money and the proceeds from U.S. Government Obligations in
accordance with the terms of this Indenture and the terms of the Securities to
the payment of principal of and interest on the Securities;

       

      
        
          
          

        

        
          -52-

          
            

          

        

        
          
          

        

      

      (b) the deposit
described in clause (a) above will not result in a breach or violation of,
or constitute a Default under, any other material agreement or instrument to
which the Company is a party or by which it is bound;

       

      (c) no Default has
occurred and is continuing (i) as of the date of such deposit (other than a
Default resulting from the borrowing of funds to be applied to such deposit and
the grant of any Lien securing such borrowing) or (ii) insofar as clause
(d) or (e) of Section 5.01 is concerned at any time during the period ending on
the 91st day after the date of such deposit or, if longer, ending on the day
following the expiration of the longest preference period applicable to the
Company in respect of such deposit (it being understood that the condition in
this clause (c) is a condition subsequent and will not be deemed satisfied until
the expiration of such period);

       

      (d) the Company has
paid or caused to be paid all sums currently due and payable by the Company
under this Indenture and under the Securities;

       

      (e) the Company has
delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel,
each stating that all conditions precedent provided for in this Indenture
relating to the termination by the Company of its obligations have been complied
with;

       

      (f) in the case of an
election under Section 7.02 or 7.03, the Company has delivered to the Trustee an
Opinion of Counsel to the effect that the Holders of such Securities will not
recognize income, gain or loss for United States federal income tax purposes as
a result of such Legal Defeasance or Covenant Defeasance and will be subject to
United States 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 or Covenant
Defeasance had not occurred, and such opinion, in the case of Legal Defeasance
under Section 7.02, must refer to and be based upon a ruling of the Internal
Revenue Service or a change in applicable United States federal income tax law
occurring after the date of this Indenture.  The defeasance would in
each case be effective when 91 days have passed since the date of the deposit in
trust.

       

      
        
          
          

        

        
          -53-

          
            

          

        

        
          
          

        

      

      
        	
                Section
      7.05  

              	
                Deposited
      Money and U.S. Government Obligations To Be Held in Trust; Other
      Miscellaneous Provisions.

              

      

       

      All money and U.S.
Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 7.04 in respect of the outstanding Securities shall
be held in trust and applied by the Trustee, in accordance with the provisions
of such Securities and this Indenture, to the payment, either directly or
through any Paying Agent, to the Holders of such Securities, of all sums due and
to become due thereon in respect of principal, premium, if any, and accrued
interest, but such money need not be segregated from other funds except to the
extent required by law.

       

      The Company shall
pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the U.S. Government Obligations deposited pursuant to Section
7.04 or the principal, premium, if any, 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 Securities.

       

      Anything in this
Article VII to the contrary notwithstanding, the Trustee shall deliver or
pay to the Company from time to time upon a request of the Company any money or
U.S. Government Obligations held by it as provided in Section 7.04 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent Legal Defeasance or Covenant Defeasance.

       

      
        	
                Section
      7.06  

              	
                Reinstatement.

              

      

       

      If the Trustee or
Paying Agent is unable to apply any money or U.S. Government Obligations in
accordance with Section 7.01, 7.02 or 7.03 by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company’s
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to this Article VII
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 7.01; provided
that if the Company has made any payment of principal of, premium, if any, or
accrued interest on any Securities because of the reinstatement of their
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

      Held by Paying Agent.

              

      

       

      In connection with
the satisfaction and discharge of this Indenture, all moneys then held by any
Paying Agent under the provisions of this Indenture shall, upon written demand
of the Company, be paid to the Trustee, or if sufficient moneys have been
deposited pursuant to Section 7.04, to the Company upon a written request of the
Company, and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.

                Moneys
      Held by Trustee.

              

      

       

      Any moneys
deposited with the Trustee or any Paying Agent or then held by the Company in
trust for the payment of the principal of, or premium, if any, or interest on
any Securities that are not applied but remain unclaimed by the Holder of such
Securities for two years after the date upon which the principal of, or premium,
if any, or interest on such Securities shall have respectively become due and
payable shall be repaid to the Company upon a written request of the Company, or
if such moneys are then held by the Company in trust, such moneys shall be
released from such trust; and the Holder of such Securities entitled to receive
such payment shall thereafter, as an unsecured general creditor, look only to
the Company for the payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money shall thereupon cease; provided
that the Trustee or any such Paying Agent, before being required to make any
such repayment, shall, at the expense of the Company, either mail to each Holder
affected, at the address shown in the register of the Securities maintained by
the Registrar pursuant to Section 2.03, or cause to be published once a
week for two successive weeks, in a newspaper published in the English language,
customarily published each Business Day and of general circulation in the City
of New York, New York, a 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 mailing or publication, any unclaimed balance of such moneys then
remaining will be repaid to the Company.  After payment to the Company
or the release of any money held in trust by the Company, Holders entitled to
the money must look only to the Company for payment as general creditors unless
applicable abandoned property law designates another Person.

Act.

              

      

       

      Every amendment to
this Indenture or the Securities shall comply in form and substance with the TIA
as then in effect.

       

      
        	
                Section
      8.04

      and Effect of

      A consent to an
amendment (which includes a supplement) or waiver by a Holder is a continuing
consent by the Holder and every subsequent Holder of a Security or portion of a
Security that evidences the same debt as the consenting Holder’s Security, even
if notation of the consent is not made on any Security.  However, any
such Holder or subsequent Holder may revoke the consent as to his or her
Security or portion of a Security if the Trustee receives written notice of
revocation at any time prior to (but not after) the date the Trustee receives an
Officers’ Certificate certifying that the Holders of the requisite principal
amount of Securities have consented (and not theretofore revoked such consent)
to the amendment, supplement or waiver.  An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every
Holder.

       

      The Company may,
but shall not be obligated to, fix a record date for the purpose of determining
the Holders entitled to consent to any amendment or waiver or to take any other
action under this Indenture.  If a record date is fixed, then
notwithstanding the provisions of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to consent to such amendment,
supplement or waiver or to revoke any consent previously given, whether or not
such Persons continue to be Holders after such record date.  No
consent shall be valid or effective for more than 90 days after such record date
unless consents from Holders of the principal amount of the Securities required
hereunder for such amendment or waiver to be effective shall have also been
given and not revoked within such 90-day period.

       

      After an amendment,
supplement or waiver becomes effective, it shall bind every Holder, unless it is
of the type described in any of clauses (a) through (g) of Section 8.02
hereof.  In such case, the amendment or waiver shall bind each Holder
who has consented to it and every subsequent Holder that evidences the same debt
as the consenting Holder’s Security.

      on or Exchange of
Securities.

              

      

       

      If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee.  The Trustee may place an
appropriate notation on the Security regarding the changed terms and return it
to the Holder.  Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Security shall issue and the Trustee
shall authenticate a new Security that reflects the changed terms. Failure to
make the appropriate notation or to issue a new Security shall not affect the
validity of such amendment.

      to Sign Amendments,

      The Trustee shall
sign any amendment, waiver or supplemental indenture authorized pursuant to this
Article VIII if the amendment, waiver or supplemental indenture does not
adversely affect the rights, duties, liabilities or immunities of the
Trustee.  If it does, the Trustee may, but need not, sign
it.  In signing or refusing to sign such amendment, waiver or
supplemental indenture, the Trustee shall receive, and subject to Section 6.01
hereof, shall be fully protected in relying upon, an Opinion of Counsel and an
Officers’ Certificate, as conclusive evidence that such amendment, waiver or
supplemental indenture is authorized or permitted by this Indenture, that it is
not inconsistent herewith, and that it will be valid and binding upon the
Company in accordance with its terms.

      to Trustee.

              

      

       

      If the Company
elects to redeem Securities pursuant to the redemption provisions specified in
the Securities, it shall furnish to the Trustee, at least 45 days but not more
than 60 days before a Redemption Date (unless the Trustee consents in writing to
a shorter period of at least 30 days prior to the Redemption Date), an Officers’
Certificate setting forth the Redemption Date, the principal amount of such
Securities to be redeemed and the Redemption Price.

       

      
        	
                Section
      9.02  

              	
                Selection
      of Securities to be
Redeemed.

              

      

       

      If less than all of
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed on a pro rata basis, by lot or by any other method that the Trustee in
its sole discretion shall deem fair and appropriate.  The particular
Securities to be redeemed shall be selected, unless otherwise provided herein,
not less than 30 days nor more than 60 days prior to the Redemption Date by the
Trustee from the outstanding Securities not previously called for
redemption.

       

      The Trustee shall
promptly notify the Company in writing of the Securities selected for redemption
and, in the case of any Security selected for partial redemption, the principal
amount thereof to be redeemed.  Securities and portions of them
selected shall be in amounts of $1,000 or whole multiples of
$1,000.  Except as provided in the preceding sentence, provisions of
this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption.

       

      
        	
                Section
      9.03  

              	
                Notices
      to Holders.

              

      

       

      (a) At least 30 days
but not more than 60 days before a Redemption Date, the Company shall mail in
conformity with Section 10.02 a notice of redemption to each Holder whose
Securities are to be redeemed.

       

      The Notice shall
identify the Securities to be redeemed (including CUSIP numbers, if any) and
shall state:

       

      (i) the Redemption
Date;

       

      (ii) the Redemption
Price;

       

      (iii) if any Security is
being redeemed in part, the portion of the principal amount of such Security to
be redeemed and that, after the Redemption Date, upon surrender of such
Security, a new Security or Securities in principal amount equal to the
unredeemed portion will be issued;

       

      
        
          
          

        

        
          -59-

          
            

          

        

        
          
          

        

      

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

       

      (v) that Securities
called for redemption must be surrendered to the Paying Agent at the address
specified in such notice to collect the Redemption Price;

       

      (vi) that unless the
Company defaults in making the redemption payment, interest on Securities called
for redemption ceases to accrue on and after the Redemption Date and the only
remaining right of the Holders is to receive payment of the Redemption Price
upon surrender to the Paying Agent of the Securities; and

       

      (vii) the aggregate
principal amount of Securities being redeemed.

       

      If any of the
Securities to be redeemed is in the form of a Global Security, then the Company
shall modify such notice to the extent necessary to accord with the procedures
of the Depositary applicable to redemptions.

       

      (b) At the Company’s
request, the Trustee shall give the notice required in Section 9.03(a) in the
Company’s name; provided,
however,
that the Company shall deliver to the Trustee, at least 45 days prior to the
Redemption Date (unless the Trustee consents in writing to a shorter period at
least 30 days prior to the Redemption Date), an Officers’ Certificate requesting
that the Trustee give such notice and setting forth the information to be stated
in such notice as provided in Section 9.03(a).

                Effect
      of Notices of
Redemption.

              

      

       

      Once notice of
redemption is mailed pursuant to Section 9.03, Securities called for redemption
become due and payable on the Redemption Date at the Redemption
Price.  Upon surrender to the Paying Agent, such Securities shall be
paid out at the Redemption Price.

       

      
        	
                Section
      9.05  

              	
                Deposit of Redemption
      Price.

              

      

       

      At or prior to
11:00 a.m. New York City time on the Redemption Date, the Company shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the Redemption
Price of all Securities to be redeemed on that date.  The Trustee or
the Paying Agent shall return to the Company any money not required for that
purpose less the expenses of the Trustee as provided herein.

       

      If the Company
complies with the preceding paragraph, interest on the Securities or portions
thereof to be redeemed (whether or not such Securities are presented for
payment) will cease to accrue on the applicable Redemption Date.  If
any Security called for redemption shall not be so paid upon surrender because
of the failure of the Company to comply with the preceding paragraph, then
interest will be paid on the unpaid principal and premium, if any, from the
Redemption Date until such principal and premium are paid and, to the extent
lawful, on any interest not paid on such unpaid principal, in each case at the
rate provided in the Securities and in Section 3.01.

      9.06  

              	
                Securities Redeemed in
      Part.

              

      

       

      Upon surrender of a
Security that is redeemed in part, the Company shall issue and the Trustee shall
authenticate for the Holder, at the expense of the Company, a new Security equal
in principal amount to the unredeemed portion of the Security
surrendered.

      7 5/8% Series [A/B]
Note due 2010

       

      This Security is
one of a duly authorized issue of 7 5/8% Series [A/B] Notes due August 1, 2010
(the “Securities”) of
El Paso Natural Gas Company, a Delaware corporation (the “Company”).

       

      1.           Interest.  The
Company promises to pay interest on the principal amount of this Security at 7
5/8% per annum from
[                ]
until maturity.  The Company will pay interest semiannually on
February 1 and August 1 of each year (each an “Interest Payment Date”), or
if any such day is not a Business Day, on the next succeeding Business
Day.  Interest on the Securities will accrue from the most recent
Interest Payment Date on which interest has been paid or, if no interest has
been paid, from
[               ];
provided that if there
is no existing Default in the payment of interest, and if this Security 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
[                    ]
and interest accrued from
[                 ]
shall be payable on such date.  Further, the Company shall pay
interest on overdue principal and premium, if any, from time to time on demand
at a rate equal to the interest rate then in effect; it shall pay interest on
overdue installments of interest (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 of
twelve 30-day months.

       

      2.           Method of
Payment.  The Company will pay interest on the Securities
(except defaulted interest) to the Persons who are registered Holders of
Securities at the close of business on the record date next preceding the
Interest Payment Date, even if such Securities are canceled after such record
date and on or before such Interest Payment Date.  The Holder must
surrender this Security to a Paying Agent to collect payments of principal and
premium, if any.  The Company will pay the principal of, and premium,
if any, and interest on the Securities in money of the United States that at the
time of payment is legal tender for payment of public and private
debts.  Payments in respect of the Securities represented by a Global
Security (including principal, premium, if any, Liquidated Damages, if any, and
interest) will be made by wire transfer of immediately available funds to the
accounts specified by The Depository Trust Company. The Company will make all
payments in respect of a certificated Security (including principal, premium, if
any, Liquidated Damages, if any, and interest) by mailing a check to the
registered address of each Holder thereof; provided, however, that payments on a
certificated Security will be made by wire transfer to a U.S. dollar account
maintained by the payee with a bank in the United States if such Holder elects
payment by wire transfer by giving written notice to the Trustee or the Paying
Agent to such effect designating such account no later than 30 days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      3.           Ranking.  The
Securities are senior unsecured obligations of the Company.

       

      4.           Optional
Redemption.  The Securities may be redeemed, in whole or part,
at the Company’s option at any time in whole, or from time to time in part,
prior to August 1, 2007, at the Make-Whole Price (as defined below) in
accordance with the provisions of the Indenture.

       

      “Make-Whole Price” means an
amount equal to the greater of

       

      (i)           100%
of the principal amount of the Securities then outstanding to be redeemed,
and

       

      (ii)           as
determined by an Independent Investment Banker, the sum of the present values of
(A) the redemption price of the Securities at August 1, 2007 (as set forth
below) and (B) the remaining scheduled payments of interest from the Redemption
Date to August 1, 2007 (not including any portion of such payments of interest
accrued as of the Redemption Date) discounted back to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Rate plus 75 basis points,

       

      plus, in the case
of both (i) and (ii), accrued and unpaid interest and Liquidated Damages, if
any, to the Redemption Date.  Unless the Company defaults in the
payment of the Make-Whole Price, on and after the applicable Redemption Date,
interest shall cease to accrue on the Securities to be redeemed.

       

      “Comparable Treasury Issue”
means the U.S. Treasury security selected by an Independent Investment Banker as
having a maturity comparable to the remaining term of the Securities to be
redeemed 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 term of the Securities.

       

      “Comparable Treasury Price”
means, with respect to any Redemption Date, (i) the average of four Reference
Treasury Dealer Quotations for such Redemption Date, after excluding the highest
and lowest of such Reference Treasury Dealer Quotations, or (ii) if the Trustee
obtains fewer than four such Reference Treasury Dealer Quotations, the average
of all such Reference Treasury Dealer Quotations.

       

      “Independent Investment
Banker” means Citigroup Global Markets Inc. or Credit Suisse First Boston
LLC and their respective successors at the Company’s option, or, if such firms
or the successors, if any, to such firms, as the case may be, are unwilling or
unable to select the Comparable Treasury Issue, an independent investment
banking institution of national standing appointed by the Company.

       

      “Reference Treasury Dealer”
means Citigroup Global Markets Inc. or Credit Suisse First Boston LLC, at the
Company’s option, and three additional primary U.S. government securities
dealers in New York City (each a “Primary Treasury Dealer”) selected by the
Company, and their respective successors; provided, however, that if
any such firm or any such successor, as the case may be, shall cease to be a
primary U.S. government securities dealer in New York City, the Company shall
substitute therefore another Primary Treasury Dealer.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      “Reference Treasury Dealer
Quotations” means, with respect to each Reference Treasury Dealer and any
Redemption Date, the average, as determined by the Trustee, of the bid and asked
prices for the Comparable Treasury Issue (expressed in each case as a percentage
of its principal amount) quoted in writing to the Trustee by such Reference
Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day
preceding such Redemption Date.

       

      “Treasury Rate” means, with
respect to any Redemption Date, (i) the yield, under the heading which
represents the average for the immediately preceding week, appearing in the most
recently published statistical release designated “H.15(519)” or any successor
publication that is published weekly by the Board of Governors of the Federal
Reserve System and that establishes yields on actively traded United States
Treasury securities adjusted to constant maturity under the caption “Treasury
Constant Maturities,” for the maturity corresponding to the Comparable Treasury
Issue (if no maturity is within three months before or after the Stated
Maturity, yields for the two published maturities most closely corresponding to
the Comparable Treasury Issue shall be determined, and the Treasury Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding to the nearest month) or (ii) if such release (or any successor
release) is not published during the week preceding the calculation date or does
not contain such yields, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, calculated using a price for
the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price for such Redemption
Date.  The Treasury Rate shall be calculated on the third Business Day
preceding the Redemption Date.

       

      The notice of
redemption with respect to the foregoing redemption need not set forth the
Make-Whole Price but only the manner of calculation thereof.  The
Company shall notify the Trustee of the Make-Whole Price with respect to any
redemption promptly after the calculation thereof, and the Trustee shall not be
responsible for such calculation.

       

      Beginning on August
1, 2007, the Company may redeem the Securities, in whole or in part, at the
Company’s option at any time or from time to time, at the following redemption
prices (expressed as percentages of principal amount), plus accrued and unpaid
interest and Liquidated Damages, if any, to the applicable Redemption Date, if
redeemed during the 12-month period beginning on each August 1of the years
indicated below:

       

      
        	
                Year

              	 	
                Percentage

                2009 and
      thereafter

              	 	
                100.000%

              

      

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      5.           Paying Agent and
Registrar.  Initially, Wilmington Trust Company (the “Trustee”), the Trustee under
the Indenture, will act as Paying Agent and Registrar.  The Company
may change any Paying Agent, Registrar, co-registrar or additional paying agent
without notice to any Holder.  The Company or any of its Subsidiaries
may act in any such capacity.

       

      6.           Indenture.  The
Company issued the Securities under an Indenture dated as of July 21, 2003 (as
amended, supplemented or otherwise modified form time to time, the “Indenture”) between the
Company and the Trustee.  The terms of the Securities include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb), as
in effect on the date of execution of the Indenture (the “TIA”).  The
Securities are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms.  The Securities
are unsecured general obligations of the Company.  Capitalized terms
used but not defined in this Security have the respective meanings given to such
terms in the Indenture.  The Company may issue Additional Securities
under the Indenture subject to compliance with Section 3.08 thereof, unlimited
in aggregate principal amount.

       

      7.           Denominations, Transfer,
Exchange.  The Securities are in registered form without
coupons in denominations of $1,000 and integral multiples of
$1,000.  The transfer of  Securities may be registered and
Securities 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 to pay any taxes and fees
required by law or permitted by the Indenture.  The Registrar need not
exchange or register the transfer of any Securities during the period between a
record date and the corresponding Interest Payment Date.

       

      8.           Persons Deemed
Owners.  The registered Holder of a Security shall be treated
as its owner for all purposes.

       

      9.           Amendments and
Waivers.  Subject to certain exceptions and limitations, the
Indenture or the Securities may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Securities, and compliance in a particular instance by the Company with any
provision of the Indenture may be waived (other than certain provisions,
including any continuing Default or Event of Default in the payment of the
principal of, or premium, if any, or interest on the Securities) by the Holders
of at least a majority in principal amount of the Securities then outstanding in
accordance with the terms of the Indenture.  Without the consent of
any Holder, the Company and the Trustee may amend or supplement the Indenture or
the Securities to cure any ambiguity, omission, defect or inconsistency; to
comply with the Indenture in the case of the merger, consolidation or sale or
other disposition of all or substantially all of the assets of the Company; to
provide for uncertificated Securities in addition to or in place of certificated
Securities; to add any additional Events of Default; to provide for the
acceptance under the Indenture of a successor trustee in compliance with the
provisions thereof; to secure the Securities pursuant to the requirements under
the Indenture; to comply with any requirements in order to effect or maintain
the qualification of the Indenture under the TIA; to comply with any
requirements of the SEC in connection with qualifying the Indenture under the
TIA; to add to the covenants of the Company for the benefit of the Holders or to
surrender any power conferred upon the Company; or to make any change that does
not adversely affect the rights of any Holder in any material
respect.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      The right of any
Holder to participate in any consent required or sought pursuant to any
provision of the Indenture (and the obligation of the Company to obtain any such
consent otherwise required from such Holder) may be subject to the requirement
that such Holder shall have been the Holder of record of any Securities with
respect to which such consent is required or sought as of a date identified by
the Trustee in a notice furnished to Holders in accordance with the terms of the
Indenture.

       

      Without the consent
of each Holder affected, the Company may not (i) reduce the percentage of
principal amount of Securities whose Holders must consent to an amendment,
supplement or waiver, (ii) reduce the rate of or change the time for payment of
interest, including default interest, on any Security, (iii) reduce the
principal of or change the fixed maturity of any Security or alter the premium
or other provisions with respect to redemption, (iv) change the place of
payment or make any Security payable in money other than that stated in the
Security, (v) impair the right to institute suit for the enforcement of any
payment of principal of, or premium, if any, or interest on any Security, (vi)
make any change in the percentage of principal amount of Securities necessary to
waive compliance with certain provisions of the Indenture or (vii) waive a
continuing Default or Event of Default in the payment of principal of, or
premium, if any, or interest on the Securities.

       

      10.           Defaults and
Remedies.  Generally, an Event of Default occurs
if:  (i) the Company defaults in the payment of any interest or
Liquidated Damages, if any, on any Security when it becomes due and payable, and
the default continues for 30 days; (ii) the Company defaults in the payment of
the principal of, or premium, if any, on, any Security at its Maturity; (iii)
the Company defaults in the performance, or breach, of any other term, covenant
or warranty of the Company in the Indenture, and the default or breach continues
for a period of 60 days after there has been given, by registered or certified
mail, to the Company by the Trustee or to the Company and the Trustee by the
Holders of at least 25% in principal amount of the outstanding Securities of
that series a written notice specifying the default or breach and requiring it
to be remedied and stating that such notice is a "Notice of Default" hereunder;
(iv) certain events of bankruptcy or liquidation with respect to the Company
occur; or (v) the Company defaults under any debt or under any instrument under
which there may be issued or by which there may be secured or evidenced any debt
for money borrowed by the Company or any of its Restricted Subsidiaries or under
any guarantee of payment by the Company or any of its Restricted Subsidiaries of
debt for money borrowed (other than a default under any debt of El Paso or one
or more Subsidiaries of El Paso (other than the Company or any of its Restricted
Subsidiaries) guaranteed by one or more of the Company’s Restricted
Subsidiaries), whether such debt or guarantee now exists or shall hereafter be
created, and the effect of such default is to result in such debt becoming due
prior to its stated maturity; provided, however, that no Event of Default under
this clause (v) shall exist if all such defaults do not relate to such debt or
such guarantees with an aggregate principal amount in excess of $25 million at
the time outstanding; and provided further, that if such default under such
bond, debenture, note or other evidence of debt for borrowed money or mortgage,
indenture or other instrument shall be cured by the Company or its Restricted
Subsidiary, or be waived by the holders of such debt, in each case as may be
permitted by such bond, debenture, note or other evidence of debt for borrowed
money or any mortgage, indenture or other instrument, then the Event of Default
under this clause (v) by reason of such default shall be deemed likewise to have
been thereupon cured or waived.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      If an Event of
Default (other than an Event of Default specified in clause (iv) above) occurs
and is continuing, the Trustee may, by notice to the Company, or the Holders of
at least 25% in principal amount of the then outstanding Securities may declare
by notice to the Company and the Trustee, and the Trustee shall, upon the
request of such Holders the principal of, premium, if any, and accrued and
unpaid interest and Liquidated Damages, if any, on all then outstanding
Securities (if not then due and payable) to be immediately due and payable, and
upon any such declaration the same shall become and be immediately due and
payable.  The amount due and payable upon the acceleration of any
Security is equal to 100% of the principal amount thereof plus premium, if any,
and accrued and unpaid interest and Liquidated Damages, if any, to the date of
payment.  Holders may not enforce the Indenture or the Securities
except as provided in the Indenture.  If an Event of Default specified
in clause (iv) above with respect to the Company occurs, the principal of,
premium, if any, on, accrued and unpaid interest on, and Liquidated Damages, if
any, on all Securities then outstanding shall ipso facto become and be
immediately due and payable without any declaration, notice or other act on the
part of the Trustee or any Holder.

       

      11.           Discharge Prior to Maturity.
The Indenture shall be discharged and canceled upon the payment of all of the
Securities and shall be discharged except for certain obligations upon the
irrevocable deposit with the Trustee of funds or U.S. Government Obligations
sufficient for such payment.

       

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

       

      13.           No Recourse Against Others. A
director, officer, employee or stockholder, as such, of the Company or of any
Affiliate shall not have any liability for any obligations of the Company under
the Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation by reason of his, her or its status
as such.  Each Holder by accepting a Security waives and releases all
such liability.  The waiver and release are part of the consideration
for the issuance of the Securities.

       

      14.           Authentication.  This
Security shall not be valid until authenticated by the manual signature of the
Trustee or an authenticating agent.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      15.           CUSIP
Numbers.  Pursuant to a recommendation promulgated by the
Committee on Uniform Security 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 numbers as printed on the Securities and reliance may be placed
only on the other identification numbers printed thereon.

       

      16.           Abbreviations.  Customary
abbreviations may be used in the name of a Holder or an assignee, such
as:  TEN COM (= tenants 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).

       

      17.           Governing
Law.  THE
INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUCTED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK.  TO THE FULLEST EXTENT IT MAY
EFFECTIVELY DO SO UNDER APPLICABLE LAW, THE COMPANY HEREBY IRREVOCABLY SUBMITS

MAILING.  NOTWITHSTANDING THE FOREGOING, NOTHING HEREIN SHALL AFFECT
THE RIGHT OF ANY HOLDER OF SECURITIES TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST
THE COMPANY IN ANY OTHER JURISDICTION.

       

      18.           [Additional
Rights and Obligations of Holders of Transfer Restricted
Securities.  In addition to the rights provided to Holders of
Securities under the Indenture, Holders of Transfer Restricted Securities shall
have all the rights set forth in the Registration Rights Agreement applicable to

      In connection with

prior to the expiration of the period referred to in Rule 144(k) under the
Securities Act after the later of the date of original issuance of such
Securities and the last date, if any, on which such Securities were owned by the

Securities are being transferred as specified below:

       

       

      CHECK

                (1)    o

              	
                to the
      Company or a Subsidiary thereof; or

              
	
                (2)    o

              	
                to a “qualified institutional
      buyer” (as defined in Rule 144A under the Securities Act of 1933)
      that purchases for its own account or for the account of a qualified
      institutional buyer to whom notice is given that such transfer is being
      made in reliance on Rule 144A, in each case pursuant to and in compliance
      with Rule 144A under the Securities Act of 1933; or

              
	
                (3)    o

              	
                outside the
      United States to a “foreign person” in compliance with Rule 904 of
      Regulation S under the Securities Act of 1933; or

              
	
                (4)    o

              	
                to an
      institutional “accredited investor” (within the meaning of subparagraph
      (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act of
      1933); or

              

      

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      
        	
                (5)    o

              	
                pursuant to
      an effective registration statement under the Securities Act of 1933;
      or

              
	
                (6)    o

              	
                pursuant to
      an exemption from the registration requirements of the Securities Act of
      1933, provided by Rule 144
thereunder.

              

      

       

      and unless the box
below is checked, the undersigned confirms that such Security is not being
transferred to an “affiliate” of the Company as defined in Rule 144 under the
Securities Act of 1933 (an “Affiliate”):

       

        The
transferee is an Affiliate of the Company.

       

      Unless one
of  items (1) through (6) above is checked, the Trustee will refuse to
register any of the Securities evidenced by this certificate in the name of any
person other than the registered Holder thereof; provided, however, that if item (3),
(4) or (5) is checked, the Company or the Trustee may require, prior to
registering any such transfer of the Securities, in their sole discretion, such
written legal opinions, certifications (including an investment letter, and in
the case of a transfer pursuant to item (3) or (4), a Regulation S Letter or
Transferee Letter, in each case, in substantially the form set forth below) and
other information as the Trustee or the Company have reasonably requested to
confirm that such transfer is being made pursuant to an exemption from, or in a
transaction not subject to, the registration requirements of the Securities Act
of 1933.

       

      If none of the
foregoing items are checked, the Trustee or Registrar shall not be obligated to
register this Security in the name of any person other than the Holder hereof
unless and until the conditions to any such transfer of registration set forth
herein and in Section 2.06 of the Indenture shall have been
satisfied.

    This Security is
one of a duly authorized issue of Securities of the Company (the “Securities”),
issued and to be issued in one or more series under an Indenture dated as of
November 13, 1996 (as supplemented through the date hereof, the “Indenture”),
between the Company and JPMorgan Chase Bank (formerly known as The Chase
Manhattan Bank), as Trustee (the “Trustee,” which term includes any successor

Securities of the series without the consent or approval of the holders of
Outstanding Securities, may mature at different times, may bear interest, if
any, at different rates, may be subject to different redemption provisions, if
any, may be subject to different sinking, purchase or analogous funds, if any,
may be subject to different covenants and Events of Default and may

    otherwise vary as
in the Indenture provided or permitted. This Security is one of a series of
Securities designated on the face hereof limited in aggregate principal amount
to U.S. $300,000,000, except that in accordance with the provisions of the
Indenture the series of Securities may be reopened in the future without the
consent of the holders of the then Outstanding Securities to issue additional
Securities of this series.

     

    The Securities of
this series are redeemable, upon not less than 30 nor more than 60 days’ notice
by mail, as a whole or in part, at the option of the Company at any time at the
“Make-Whole Price.”  As used herein, the term “Make-Whole Price” means
an amount equal to the greater of:

     

    
      	
               
      

            	
              (1)

            	
              100% of the
      principal amount of the Securities of this series to be redeemed;
      and

            

    

     

    
      	
               
      

            	
              (2)

            	
              as determined
      by an Independent Investment Banker, the sum of the present values of the
      remaining scheduled payments of principal and interest on the Securities
      to be redeemed (not including any portion of such payments of interest
      accrued as of the Redemption Date) discounted back to the Redemption Date
      on a semi-annual basis (assuming a 360-day year consisting of twelve
      30-day months) at the Treasury Rate (as defined below) plus 50 basis
      points.

            

    

     

    plus, in the case
of both (1) and (2), accrued and unpaid interest to the Redemption Date, but
interest installments whose Stated Maturity is on or prior to such Redemption
Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the
Indenture.  On and after the applicable Redemption Date, interest will
cease to accrue on the Securities of this series to be redeemed, unless a
default is made in payment of the Make-Whole Price.

     

    “Comparable
Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining
term of the Securities of this series to be redeemed 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 term of the Securities of this series.

     

    “Comparable
Treasury Price” means, with respect to any Redemption Date, (1) the average of
four Reference Treasury Dealer Quotations for such Redemption Date, after
excluding the highest and lowest of such Reference Treasury Dealer Quotations,
or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Reference Treasury Dealer
Quotations.

     

    “Independent
Investment Banker” means Credit Suisse First Boston Corporation and its
successors, or, if such firm or the successors, if any, to such firm, as the
case may be, are unwilling or unable to select the Comparable Treasury Issue, an
independent investment banking institution of national standing appointed by the
Trustee after consultation with the Company.

     

    “Reference Treasury
Dealer” means Credit Suisse First Boston Corporation and three additional
primary U.S. government securities dealers in New York City (each a “Primary
Treasury Dealer”) selected by the Trustee after consultation with the Company,
and their respective successors (provided,
however,
that if any such firm or any such successor, as the case may be, shall cease to
be a primary U.S. government securities dealer in New York City, the Trustee,
after consultation with the Company, shall substitute therefor another Primary
Treasury Dealer).

     

    
      
        
        

      

      
        A1-4

        
          

        

      

      
        
        

      

    

    “Reference Treasury
Dealer Quotations” means, with respect to each Reference Treasury Dealer and any
Redemption Date, the average, as determined by the Trustee, of the bid and asked
prices for the Comparable Treasury Issue (expressed in each case as a percentage
of its principal amount) quoted in writing to the Trustee by such Reference
Treasury Dealer at 5:00 p.m. on the third Business Day preceding such Redemption
Date.

     

    “Treasury Rate”
means, with respect to any redemption date, (1) the yield, under the heading
which represents the average for the immediately preceding week, appearing in
the most recently published statistical release designated “H.15(519)” or any
successor publication that is published weekly by the Board of Governors of the
Federal Reserve System and that establishes yields on actively traded United
States Treasury securities adjusted to constant maturity under the caption
“Treasury Constant Maturities,” for the maturity corresponding to the Comparable
Treasury Issue (if no maturity is within three months before or after the Stated
Maturity, yields for the two published maturities most closely corresponding to
the Comparable Treasury Issue shall be determined, and the Treasury Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding to the nearest month) or (2) if such release (or any successor release)
is not published during the week preceding the calculation date or does not
contain such yields, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, calculated using a price for
the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price for such Redemption
Date.  The Treasury Rate shall be calculated on the third Business Day
preceding the Redemption Date.

     

    In the event of
redemption of this Security in part only, a new Security or Securities of this
series and of like tenor for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

     

    If an Event of
Default with respect to the Securities of this series shall occur and be
continuing, the principal of the Securities of this series may be declared due
and payable in the manner and with the effect provided in the
Indenture.

     

    The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of
the Holders of the Securities of each series to be affected under the Indenture
at any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Outstanding Securities of all
series to be affected (voting as one class).  The Indenture also
contains provisions permitting the Holders of a majority in aggregate principal
amount of the Outstanding Securities of all affected series (voting as one
class), on behalf of the Holders of all Securities of such series, to waive
compliance by the Company with certain provisions of the
Indenture.  The Indenture permits, with certain exceptions as therein
provided, the Holders of a majority in aggregate principal amount of Securities
of any series then Outstanding to waive past defaults under the Indenture with
respect to such series and their consequences.  Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

    As provided in and
subject to the provisions of the Indenture, the Holder of this Security shall
not have the right to institute any proceeding with respect to the Indenture or
for the appointment of a receiver or trustee or for any other remedy thereunder,
unless such Holder shall have previously given the Trustee written notice of a
continuing Event of Default with respect to the Securities of this series, the
Holders of not less than 25% in principal amount of the Securities of this
series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered
the Trustee reasonable indemnity and the Trustee shall not have received from
the Holders of a majority in principal amount of the Securities of this series
at the time Outstanding a direction inconsistent with such request, and shall
have failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity.  The foregoing shall not apply
to any suit instituted by the Holder of this Security for the enforcement of any
payment of principal hereof or interest hereon on or after the respective due
dates expressed herein.

     

    Holders shall have
a right to receive Additional Interest with respect to the Securities of this
series under certain circumstances set forth in the Registration Rights
Agreement dated as of the date hereof between the Company and Credit Suisse
First Boston Corporation.

     

    No reference herein
to the Indenture and no provision of this Security or of 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 at the times, place(s) and rate, and in the coin or currency, herein
prescribed.

     

    This Global
Security or portion hereof may not be exchanged for Definitive Securities except
in the limited circumstances provided in the Indenture.

     

    The holders of
beneficial interests in this Global Security will not be entitled to receive
physical delivery of Definitive Securities except as described in the Indenture

provided in the Indenture and subject to certain limitations therein set forth,

for a like aggregate principal amount of Securities of this series and of like
tenor of a different authorized denomination, as requested by the Holder
surrendering the same.

     

    No service charge
shall be made for any such registration of transfer or exchange, but the Company
may require payment of a sum sufficient to cover any transfer tax or other
similar governmental charge payable in connection therewith.

     

    Prior to due
presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in

nor any such agent shall be affected by notice to the contrary.

     

    No recourse under
or upon any obligation, covenant or agreement of or contained in the Indenture
or of or contained in any Security, or for any claim based thereon or otherwise
in respect thereof, or in any Security, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or of any successor Person, either directly or through the Company or
any successor Person, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment, penalty or otherwise; it being
expressly understood that all such liability is hereby expressly waived and
released by the acceptance hereof and as a condition of, and as part of the
consideration for, the Securities and the execution of the
Indenture.

     

    The Indenture
provides that the Company (a) will be discharged from any and all obligations in
respect of the Securities (except for certain obligations described in the
Indenture), or (b) need not comply with certain restrictive covenants of the
Indenture, in each case if the Company deposits, in trust, with the Trustee
money or U.S. Government Obligations (or a combination thereof) which through
the payment of interest thereon and principal thereof in accordance with their
terms will provide money, in an amount sufficient to pay all the principal of
and interest of the Securities, but such money need not be segregated from other
funds except to the extent required by law.

     

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

Defaulted Interest to be fixed by the Trustee, notice of which shall be given to
Holders of Securities of this series not less than 10 days prior to such Special
Record Date, or be paid at such time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in such Indenture.

public and private debts, or at such other offices or agencies as the Company
may designate; provided, however, that payment of

    THE RIGHTS
ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE CONDITIONS AND
PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS SPECIFIED IN
THE SUPPLEMENT TO THE INDENTURE (AS DEFINED HEREIN) RELATING TO THIS GLOBAL
NOTE.  NEITHER THE HOLDER NOR THE BENEFICIAL OWNERS OF THIS REGULATION
S TEMPORARY GLOBAL NOTE SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST
HEREON.

     

    THIS NOTE (OR ITS
PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION
UNDER THE UNITED STATES SECURITIES ACT OF 1933 (THE “SECURITIES ACT”) AND THIS
NOTE MAY NOT BE OFFERED, SOLD, PLEDGED, OR OTHERWISE TRANSFERRED IN THE ABSENCE
OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM.  EACH
PURCHASER OF THIS NOTE IS HEREBY NOTIFIED THAT THE SELLER OF THIS NOTE MAY BE
RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT
PROVIDED BY RULE 144A THEREUNDER.

     

    THE HOLDER OF THIS
NOTE AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS NOTE MAY BE OFFERED,
RESOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (I) IN THE UNITED STATES TO A
PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER
(AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE
REQUIREMENTS OF RULE 144A, (II) OUTSIDE THE UNITED STATES IN AN OFFSHORE
TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (III) PURSUANT
TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144
THEREUNDER (IF AVAILABLE) OR (IV) PURSUANT TO AN EFFECTIVE REGISTRATION

ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED
STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO,
NOTIFY ANY PURCHASER OF THIS NOTE FROM IT OF THE RESALE RESTRICTIONS REFERRED TO
IN CLAUSE (A) ABOVE.

     

    This Security is
one of a duly authorized issue of Securities of the Company (the “Securities”),
issued and to be issued in one or more series under an Indenture dated as of
November 13, 1996 (as supplemented through the date hereof, the “Indenture”),
between the Company and JPMorgan Chase Bank (formerly known as The Chase
Manhattan Bank), as Trustee (the “Trustee,” which term includes any successor
trustee under the Indenture), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights,
limitations of rights, obligations, duties and immunities thereunder of the
Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and
delivered.  As provided in the Indenture, the Securities 

    
      
        
        

      

      
        A2-4

        
          

        

      

      
        
        

      

    

    may be issued in
one or more series, which different series may be issued in various aggregate
principal amounts, may provide for re-opening in the future to issue additional
Securities of the series without the consent or approval of the holders of
Outstanding Securities, may mature at different times, may bear interest, if
any, at different rates, may be subject to different redemption provisions, if
any, may be subject to different sinking, purchase or analogous funds, if any,
may be subject to different covenants and Events of Default and may otherwise
vary as in the Indenture provided or permitted.  This Security is one
of a series of Securities designated on the face hereof limited in aggregate
principal amount to U.S. $300,000,000, except that in accordance with the
provisions of the Indenture the series of Securities may be reopened in the
future without the consent of the holders of the then Outstanding Securities to
issue additional Securities of this series.

     

    The Securities of
this series are redeemable, upon not less than 30 nor more than 60 days’ notice
by mail, as a whole or in part, at the option of the Company at any time at the
“Make-Whole Price.”  As used herein, the term “Make-Whole Price” means
an amount equal to the greater of:

     

    
      	
               
      

            	
              (1)

            	
              100% of the
      principal amount of the Securities to be redeemed;
  and

            

    

     

    
      	
               
      

            	
              (2)

            	
              as determined
      by an Independent Investment Banker, the sum of the present values of the
      remaining scheduled payments of principal and interest on the Securities
      to be redeemed (not including any portion of such payments of interest
      accrued as of the Redemption Date) discounted back to the Redemption Date
      on a semi-annual basis (assuming a 360-day year consisting of twelve
      30-day months) at the Treasury Rate (as defined below) plus 50 basis
      points.

            

    

     

    plus, in the case
of both (1) and (2), accrued and unpaid interest to the Redemption Date, but
interest installments whose Stated Maturity is on or prior to such Redemption
Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the
Indenture.  On and after the applicable Redemption Date, interest will
cease to accrue on the Securities of this series to be redeemed, unless a
default is made in payment of the Make-Whole Price.

     

    “Comparable
Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining
term of the Securities of this series to be redeemed 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 term of the Securities of this series.

     

    “Comparable
Treasury Price” means, with respect to any Redemption Date, (1) the average of
four Reference Treasury Dealer Quotations for such Redemption Date, after
excluding the highest and lowest of such Reference Treasury Dealer Quotations,
or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Reference Treasury Dealer
Quotations.

     

    
      
        
        

      

      
        A2-5

        
          

        

      

      
        
        

      

    

    “Independent
Investment Banker” means Credit Suisse First Boston Corporation and its
successors, or, if such firm or the successors, if any, to such firm, as the
case may be, are unwilling or unable to select the Comparable Treasury Issue, an
independent investment banking institution of national standing appointed by the
Trustee after consultation with the Company.

     

    “Reference Treasury
Dealer” means Credit Suisse First Boston Corporation and three additional
primary U.S. government securities dealers in New York City (each a “Primary
Treasury Dealer”) selected by the Trustee after consultation with the Company,
and their respective successors (provided,
however,
that if any such firm or any such successor, as the case may be, shall cease to
be a primary U.S. government securities dealer in New York City, the Trustee,
after consultation with the Company, shall substitute therefor another Primary
Treasury Dealer).

     

    “Reference Treasury
Dealer Quotations” means, with respect to each Reference Treasury Dealer and any
Redemption Date, the average, as determined by the Trustee, of the bid and asked
prices for the Comparable Treasury Issue (expressed in each case as a percentage
of its principal amount) quoted in writing to the Trustee by such Reference
Treasury Dealer at 5:00 p.m. on the third Business Day preceding such Redemption
Date.

     

    “Treasury Rate”
means, with respect to any Redemption Date, (1) the yield, under the heading
which represents the average for the immediately preceding week, appearing in
the most recently published statistical release designated “H.15(519)” or any
successor publication that is published weekly by the Board of Governors of the
Federal Reserve System and that establishes yields on actively traded United
States Treasury securities adjusted to constant maturity under the caption
“Treasury Constant Maturities,” for the maturity corresponding to the Comparable
Treasury Issue (if no maturity is within three months before or after the Stated
Maturity, yields for the two published maturities most closely corresponding to
the Comparable Treasury Issue shall be determined, and the Treasury Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding to the nearest month) or (2) if such release (or any successor release)
is not published during the week preceding the calculation date or does not
contain such yields, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, calculated using a price for
the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price for such Redemption
Date.  The Treasury Rate shall be calculated on the third Business Day
preceding the Redemption Date.

     

    In the event of
redemption of this Security in part only, a new Security or Securities of this
series and of like tenor for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

     

    If an Event of
Default with respect to the Securities of this series shall occur and be
continuing, the principal of the Securities of this series may be declared due
and payable in the manner and with the effect provided in the
Indenture.

    The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of
the Holders of the Securities of each series to be affected under the Indenture
at any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Outstanding Securities of all
series to be affected (voting as one class).  The Indenture also
contains provisions permitting the Holders of a majority in aggregate principal
amount of the Outstanding Securities of all affected series (voting as one
class), on behalf of the Holders of all Securities of such series, to waive
compliance by the Company with certain provisions of the
Indenture.  The Indenture permits, with certain exceptions as therein
provided, the Holders of a majority in aggregate principal amount of Securities
of any series then Outstanding to waive past defaults under the Indenture with
respect to such series and their consequences.  Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

     

    As provided in and
subject to the provisions of the Indenture, the Holder of this Security shall
not have the right to institute any proceeding with respect to the Indenture or
for the appointment of a receiver or trustee or for any other remedy thereunder,
unless such Holder shall have previously given the Trustee written notice of a
continuing Event of Default with respect to the Securities of this series, the
Holders of not less than 25% in principal amount of the Securities of this
series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered
the Trustee reasonable indemnity and the Trustee shall not have received from
the Holders of a majority in principal amount of the Securities of this series
at the time Outstanding a direction inconsistent with such request, and shall
have failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity.  The foregoing shall not apply
to any suit instituted by the Holder of this Security for the enforcement of any
payment of principal hereof or interest hereon on or after the respective due
dates expressed herein.

     

    Holders shall have
a right to receive Additional Interest with respect to the Securities of this
series under certain circumstances set forth in the Registration Rights
Agreement dated as of the date hereof between the Company and Credit Suisse
First Boston Corporation.

     

    No reference herein
to the Indenture and no provision of this Security or of 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 at the times, place(s) and rate, and in the coin or currency, herein
prescribed.

     

    [This Global
Security or portion hereof may not be exchanged for Definitive Securities except
in the limited circumstances provided in the Indenture.

     

    The holders of
beneficial interests in this Global Security will not be entitled to receive
physical delivery of Definitive Securities except as described in the Indenture
and will not be considered the Holders hereof for any purpose under the
Indenture.]*

Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized
denominations and for a like aggregate principal amount, will be issued to the
designated transferee or transferees.]**

     

    The Securities of
this series are issuable only in registered form, without coupons, in
denominations of U.S. $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
the Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

     

    No service charge
shall be made for any such registration of transfer or exchange, but the Company
may require payment of a sum sufficient to cover any transfer tax or other
similar governmental charge payable in connection therewith.

     

    Prior to due
presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this Security is registered as the owner hereof for all purposes,
whether or not this Security be overdue, and neither the Company, the Trustee
nor any such agent shall be affected by notice to the contrary.

     

    No recourse under
or upon any obligation, covenant or agreement of or contained in the Indenture
or of or contained in any Security, or for any claim based thereon or otherwise
in respect thereof, or in any Security, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or of any successor Person, either directly or through the Company or
any successor Person, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment, penalty or otherwise; it being
expressly understood that all such liability is hereby expressly waived and
released by the acceptance hereof and as a condition of, and as part of the
consideration for, the Securities and the execution of the
Indenture.

     

    The Indenture
provides that the Company (a) will be discharged from any and all obligations in
respect of the Securities (except for certain obligations described in the
Indenture), or (b) need not comply with certain restrictive covenants of the
Indenture, in each case if the Company deposits, in trust, with the Trustee
money or U.S. Government Obligations (or a combination thereof) which through
the payment of interest thereon and principal thereof in accordance with their
terms will provide money, in an amount sufficient to pay all the principal of
and interest of the Securities, but such money need not be segregated from other
funds except to the extent required by law.
