    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.

    

             The
Trustee shall authenticate (i) for original issue on the Initial Issue Date,

Officer of the Company. Such order shall specify (a) the amount of the
Securities to be authenticated and the date of original issue thereof, and (b)
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

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.

    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.

    

             The
Company initially appoints the Trustee as Registrar and Paying
Agent.

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.

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.

    

    Section 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

    

    

    

    -23-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    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.

    

             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.

    

    Section 2.11.
Temporary 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.

    

    Section 2.12.
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.

    

    Section 2.13.
Defaulted 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.

    

    

    

     -24-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    

    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.

    

    Section 2.14.
Persons Deemed Owners.

    

             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.

    

    Section 2.15. CUSIP
Numbers.

    

             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.

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.

In addition, whether or not required by the rules and regulations of the SEC,

                      (iii)
the Company fails to observe or perform any of its covenants or agreements
listed in Sections 3.05, 3.07, 3.08, 3.09 or 3.10 hereof and such Default
continues for a period of 30 days after the notice specified below;

    

                      (iv)
the Company fails to comply with any of its other covenants or agreements
contained in the Securities or this Indenture and such Default continues for a
period of 90 days after the notice specified below;

    

                      (v)
the Company or any Restricted Subsidiary defaults (A) in the payment of any
installment of principal of or interest upon any  Funded Debt having a
then outstanding principal amount in excess of $25 million, the effect of which
default is to cause or permit the trustee  or holders of such Funded
Debt to cause such Funded Debt to become due and payable prior to its Stated
Maturity; or (B) in any other manner as defined in any instrument evidencing
Funded Debt having a then outstanding principal amount in excess of $25 million,
which default has resulted in the acceleration of such Funded Debt so that the
same shall have become due and payable prior to its Stated Maturity, provided,
however, that if any default as provided in clause (A) or (B) above shall be
remedied or cured by the Company or a Restricted

    Subsidiary or
waived by the trustee or holders of such Funded Debt, in each case in accordance
with the terms of the instruments pursuant to which such Funded Debt shall have
been issued, then the default hereunder by reason thereof shall be deemed
likewise to have been thereupon remedied, cured, or waived without further
action upon the part of either the Trustee or any of the Holders; and
provided,  further, that subject to the provisions of this Indenture,
the Trustee shall not be charged with knowledge of any such default unless
either  (x) a Responsible Officer of the Trustee assigned to its
corporate trust department shall, as such officer, have actual knowledge of such
default, or (y) written notice thereof shall have been given to the Trustee by
the Company, by the trustee or holders of any such Funded Debt, or by the
Holders of not less than 25% in aggregate principal amount of the Securities at
the time outstanding;

                      (vi)
a decree or order by a court having jurisdiction in the premises shall have been
entered adjudging the Company or any Restricted Subsidiary of the Company a
bankrupt or insolvent, or approving as properly filed a petition seeking
reorganization, arrangement, adjustment, composition, liquidation, dissolution
or winding-up of the Company or any Restricted Subsidiary of the Company
or any
similar relief under any present or future federal or state law or regulation,
and such decree or order shall have continued undischarged or unstayed for a
period of 90 consecutive days; or a decree or order of a court having
jurisdiction in the premises for the appointment of a receiver or trustee or
assignee in bankruptcy or insolvency of the Company or any Restricted Subsidiary
of the Company or of its property, or for the winding-up or liquidation of its
affairs, shall have been entered, and such decree or order shall have remained
in force undischarged and unstayed for a period of 90 consecutive days;
or

    

                      (vii)
the Company or any Restricted Subsidiary shall institute proceedings to be
adjudicated a voluntary bankrupt, or shall consent to  the institution
of a bankruptcy proceeding against it, or shall file a petition or answer
or consent seeking reorganization, arrangement, adjustment, composition,
liquidation, dissolution, winding-up or any similar relief under any present or
future federal or state law or consent to the appointment of a receiver or
trustee or assignee in bankruptcy or insolvency of it or of its property, or
shall make an assignment for the benefit of creditors, or shall admit in writing
its inability to pay its debts generally as they become due.

    

             A
Default under clause (iii) or (iv) above is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the outstanding Securities notify the Company and the Trustee, of the Default
and the Company does not cure the Default within the time period specified
above. The notice must specify the Default, demand that it be remedied and state
that the notice is a "Notice of Default." When a Default is cured, it ceases.
Such notice shall be given by the Trustee if so requested by the Holders of at
least 25% in principal amount of the Securities then outstanding.

    

             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.

    

    Section 5.02.
Acceleration.

    

             If
an Event of Default (other than an Event of Default specified in clause (vi) or
(vii) 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 may, by

    notice to the
Company and the Trustee, and the Trustee shall, upon the request of such
Holders, declare

    

    

    -40-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    the principal of,
premium, if any, on, accrued and unpaid interest on, and Liquidated Damages, if
any, on all then outstanding Securities (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 (vi) or
(vii ) 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
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, by
written

    notice to the
Company and the Trustee, may rescind and annul such acceleration and its
consequences if:

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

    

                      (ii)
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

    

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

    

    Section 5.03. Other
Remedies.

    

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

    

    Section 5.04.
Waiver of Existing Defaults.

    

             Subject
to Section 5.07 and Section 8.02, the Holders of a majority in principal amount
of the outstanding Securities 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 the

    Securities or a
solicitation of consents in respect of the Securities, provided that in each
case such offer or solicitation is made to all Holders of the Securities then
outstanding on equal terms), except (1) a continuing Default or Event of Default
in the payment of the principal of, or premium, if any, or

    

    

    

    -41-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    Liquidated Damages,
if any, or interest on the Securities or (2) 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.

    

    Section 5.05.
Control by Majority.

    

             The
Holders of a majority in principal amount of the Securities 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.

    

    Section 5.06.
Limitations on Suits.

    

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

    

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

    

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

    

                      (iii)
such Holder or Holders offer to the Trustee indemnity satisfactory to the
Trustee against any loss, liability or expense;

    

                      (iv)
the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of indemnity; and

    

                      (v)
during such 60-day period the Holders of a majority in principal amount of the
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.

    Section 5.07.
Rights of Holders to Receive Payment.

    

             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.

    

    Section 5.08.
Collection Suit by Trustee.

    

             If
an Event of Default specified in clause (i) or (ii) 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, 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 the Trustee,
its agents and counsel.

    

    Section 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.

    Section 5.10.

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

    

                      First:

                      Second:

if any, Liquidated Damages, if any,  and interest ratably, without
preference or priority of any kind, according to the amounts due and payable on
the 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.

    

    Section 5.11.
Undertaking for Costs.

    

             In
any suit for the enforcement of any right or remedy under this Indenture or in
any suit against the Trustee for any action taken or omitted by it as a trustee,
a court in its discretion may require the filing by any party litigant in the
suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in the suit, having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This
Section 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

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

affairs.

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

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)

vested in it by this Indenture at the request or direction of any of the Holders

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

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.

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.

    

    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(vi) or Section 5.01(vii) 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:

    

                      (i)
the Trustee fails to comply with Section 6.10 hereof;

    

    

       -48-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    (ii) 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;

    

                      (iii)
a Custodian or public officer takes charge of the Trustee or its property;
or

    

                      (iv)
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.

    

    Section 6.09.
Successor 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.

    Section 6.10.
Eligibility; Disqualification.

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).

    

    Section 6.11.
Preferential Collection of Claims Against Company.

    

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

Liquidated Damages with respect to the Securities, not theretofore delivered to

                      (2)
the Company has paid or caused to be paid all sums payable under this Indenture
by the Company; and

    

                      (3)
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, 3.07, 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(iii), (iv) and (v) 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

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, (2) 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 (3) 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;

    

             (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 (1) 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 (2) insofar
as clause (v) or (vi) 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.

Miscellaneous Provisions.

    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.

    

    Section 7.07.
Moneys 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.

    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 hereafter, 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.

                      (vii)
to comply with any requirement in order to effect or maintain the qualification

to make any change that does not adversely affect the  rights
hereunder of any Holder in any material respect.

    

             Upon
the request of the Company accompanied by a resolution of the Board of Directors
of the Company authorizing the execution of any such supplemental indenture, and
upon receipt by the Trustee of the documents described in Section 8.06 hereof,
the Trustee shall join with the Company in the execution of any supplemental
indenture authorized or permitted by the terms of this Section 8.01 becomes
effective, the Company shall mail to the Holders of each Security affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

    

    Section 8.02. With
Consent of Holders.

    

             Except
as provided below in this Section 8.02, the Company and the Trustee may amend or
supplement this Indenture or the Securities with the written consent (including
consents obtained in connection with a tender offer or exchange offer for the
Securities or a solicitation of consents in respect of the Securities; provided
that in each case such offer or solicitation is made to all Holders of the
Securities then outstanding on equal terms) of the Holders of at least a
majority in principal amount of the Securities then outstanding.

    

             Upon
the request of the Company accompanied by a resolution of the Board of Directors
of the Company authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of the Holders as
aforesaid, and upon receipt by the Trustee of the documents described
in Section 8.06 hereof, the Trustee shall join with the Company in the execution
of such supplemental indenture.

    

             It
shall not be necessary for the consent of the Holders under this Section 8.02 to
approve the particular form of any proposed amendment, supplement or waiver, but
it shall be sufficient if such consent approves the substance
thereof.

    

             The
Holders of a majority in principal amount of the Securities then outstanding may
waive compliance in a particular instance by the Company with any provision of
this Indenture or the Securities (including waivers obtained in connection with
a tender offer or exchange offer for the Securities or a solicitation of
consents in respect of the Securities, provided that in each case such offer or
solicitation is made to all Holders of the Securities then outstanding on equal
terms).

    

             Without
the consent of each Holder affected, an amendment, supplement or waiver under
this Section may not:

    

                      (i)
reduce the percentage of principal amount of the Securities whose Holders must
consent to an amendment, supplement or waiver;

    

    

    -56-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    (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 specified in
the Securities;

    

                      (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 pursuant to
Section 5.07 and Section 5.08 hereof, except as limited by Section 5.06
hereof;

    

                      (vi)
make any change in the percentage of principal amount of the Securities
necessary to waive compliance with certain provisions of this Indenture pursuant
to Section 5.04 or Section 5.07 hereof or this clause of this Section 8.02;
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.

    

             The
right of any Holder to participate in any consent required or sought pursuant to
any provision of this 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 the 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
this Indenture.

    

    Section 8.03.
Compliance with Trust Indenture 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.
Revocation and Effect of Consents.

    

             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.

    

    

    -57-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    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 (i) through (vii)
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.

    

    Section 8.05.
Notation 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.

    

    Section 8.06.
Trustee to Sign Amendments, etc.

    

             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.

    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:

    

                      (A)      the
Redemption Date;

    

                      (B)      the
Redemption Price;

    

                      (C)
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;

    

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

    

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

    

                      (F)
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

    

    

    

     -59-

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    

                      (G)
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).

    

    Section 9.04.
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 am 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.

    

    Section 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.

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

    

             This
Security is one of a duly authorized issue of 8 7/8% Series [A/B] Notes due
March 15, 2010 (the "Securities") of Southern Natural Gas Company, a Delaware
corporation (the "Company").

    

             1.
Interest. The Company promises to pay interest on the principal amount of this
Security at 8 7/8% per annum from [   ], [   ]
until maturity. The Company will pay interest semiannually on March 15 and
September 15 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
March 15, 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 March 15, 2007 (as set forth
below) and (B) the remaining scheduled payments of interest from the Redemption
Date to March 15, 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 Salomon Smith Barney 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 Salomon Smith Barney 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 March 15, 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 March 15 of the
years indicated below:

without notice to any Holder. The Company or any of its Subsidiaries may
act in any such capacity.

Indenture. The Company issued the Securities under an Indenture dated as of
March 5, 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

    

    A-8

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    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 the same becomes due and payable and the default continues for a
period of 30 days; (ii) the Company defaults in the payment of the principal of or
premium, if any, on any Security at its Maturity or otherwise; (iii) the Company
fails to observe or perform any of its covenants or agreements listed in
Sections 3.05, 3.07, 3.08, 3.09 or 3.10 of the Indenture and such Default
continues for a period of 30 days after the notice specified below; (iv) the
Company fails to comply with any of its other covenants or agreements contained
in the Securities or the Indenture and such Default continues for a period of 90
days after the notice specified below; (v) the Company or any Restricted
Subsidiary defaults (A) in the payment of any installment of principal of or
interest upon any Funded Debt having a then outstanding principal amount in
excess of $25 million, the effect of which default is to cause or permit the
trustee or holders of such Funded Debt to cause such Funded Debt to become due
and payable prior to its Stated Maturity; or (B) in any other manner as defined
in any instrument evidencing Funded Debt having a then outstanding principal
amount in excess of $25 million, which default has resulted in the acceleration
of such Funded Debt so that the same shall have become due and payable prior to
its Stated Maturity, provided, however, that if any default as provided in
clause (A) or (B) above shall be remedied or cured by the Company or a
Restricted subsidiary or waived by the trustee or holders of such Funded Debt,
in each case in accordance with the terms of

    

    A-9

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    the instruments
pursuant to which such Funded Debt shall have been issued, then the Default
hereunder by reason thereof shall be deemed likewise to have been thereupon
remedied, cured, or waived without further action upon the part of either the
Trustee or any of the Holders; and provided, further that subject to the
provisions of the Indenture, the Trustee shall not be charged with knowledge of
any such default unless either (x) a Responsible Officer of the Trustee assigned
to its corporate trust department shall, as such officer, have actual knowledge
of such default, or (y) written notice thereof shall have been given to the
Trustee by the Company, by the trustee or holders of any such Funded Debt, or by
the Holders of not less than 25% in aggregate principal amount of the Securities
at the time outstanding; or (vi) certain events of bankruptcy or liquidation
with respect to the Company occur. A Default under clause (iii) or (iv) is not
an Event of Default until the Trustee notifies the Company, or the Holders of at
least 25% in principal amount of the outstanding Securities notify the Company
and the Trustee of the Default and the Company does not
cure the Default within the time period specified above. The notice must specify
the Default, demand that it be remedied and state that the notice is a "Notice
of Default." When a Default is cured, it ceases. Such notice shall be given by
the Trustee if so requested by the Holders of at least 25% in principal amount
of the Securities then outstanding.

    

             If
an Event of Default (other than an Event of Default specified in clause (vi)
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 (vi) 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
obliga- tions of the Company under the Securities or the Indenture or for any
claim

    

    A-10

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    

    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.

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

"foreign person" in compliance with Rule 904 of Regulation S under
the  Securities Act of 1933; or

    

    (4)[
]       to an institutional "accredited

represent that:

    

                      (i)
the offer of the Securities was not made to a person in the United

                      (ii)
at the time the buy order was originated, the transferee was outside the United

                      (iii)
no directed selling efforts have been made by us in the United States in
contravention of the requirements of Rule 903(b) or Rule 904(b) of Regulation S,
as applicable; and

    

                      (iv)

             In
connection with our proposed purchase of $[   ] principal amount
of the above referenced Securities (the "Securities"), we confirm
that:

    

                      (i)
We have received such information as we deem necessary in order to make our
investment decision.

    

                      (ii)
We understand that any subsequent transfer of the Securities or any interest
therein is subject to certain restrictions  and conditions set forth
in the Indenture and the undersigned agrees to be bound by, and not to resell,
pledge or otherwise transfer the Securities or any interest therein except in
compliance with, such restrictions and conditions and the United States
Securities Act of 1933, as amended (the "Securities Act").

    

                      (iii)
We understand that the offer and sale of the Securities have not been registered
under the Securities Act, and that the Securities and any interest therein may
not be offered or sold except as permitted in the following sentence. We agree,
on our own behalf and on behalf of any accounts for which we are acting as
hereinafter stated, that if we should sell the Securities or any interest
therein, we will do so only (A) to the Company or any subsidiary thereof, (B) in
accordance with Rule 144A under the Securities Act to a "qualified institutional
buyer" (as defined therein), (C) to an institutional "accredited investor" (as
defined below) that, prior to such transfer, furnishes (or has furnished on its
behalf by a U.S. broker-dealer) to  you and to the Company a signed
letter substantially in the form of this letter, (D) outside the United States
in accordance with Rule 904 of Regulation S under the Securities Act, (E)
pursuant to the provisions of Rule 144(k) under the Securities Act or (F)
pursuant to an effective registration statement under the Securities Act, and we
further agree to provide to any person purchasing the certificated Security or
beneficial interest in a Global Security from the Company in a transaction
meeting the requirements of clauses (A) through (E) of  this paragraph
a notice advising such purchaser that resales thereof are restricted as stated
herein.

    (iv) We understand
that, on any proposed resale of the Security or beneficial interest therein, we
will be required to furnish to you and the Company such certifications, legal
opinions and other information as you and the Company may reasonably require to
confirm that the proposed sale complies with the foregoing restrictions. We
further understand that the Security purchased by the Company will
bear

    a

                      (v)
We are an institutional "accredited investor" (as defined in Rule 501(a)(1),
(2), (3) or (7) of Regulation D under the Securities Act) and have such
knowledge and experience in financial and business matters as to be capable of
evaluating the merits and risks of our investment in the Security, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or its investment.

    

                      (vi)
We are acquiring the Security or beneficial interest therein purchased by the
Company for our own account or for one or more accounts (each of which is an
institutional "accredited investor") as to each of which we
exercise sole investment discretion.

    

             You
and the Company are entitled to rely upon this letter and are irrevocably
authorized to produce this letter or a copy hereof to any interested party in
any administrative or legal proceedings or official inquiry with respect to the
matters covered hereby.
