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

Section 104.  Acts of Holders; Record Dates.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the
Company and the Guarantor. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred


                                      -12-
   21

to as the "Act" of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Indenture and (subject to Section 601)
conclusive in favor of the Trustee, the Company and the Guarantor, if made in
the manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him or her the execution thereof.
Where such execution is by a signer acting in a capacity other than such
signer's individual capacity, such certificate or affidavit shall also
constitute sufficient proof of such signer's authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which the Trustee
deems sufficient.

                  (c) The Company or the Guarantor may, in the circumstances
permitted by the Trust Indenture Act, fix any day as the record date for the
purpose of determining the Holders of Outstanding Securities of any series
entitled to give or take any request, demand, authorization, direction, notice,
consent, waiver or other action, or to vote on any action, authorized or
permitted to be given or taken by Holders of Outstanding Securities of such
series. If not set by the Company or the Guarantor prior to the first
solicitation of a Holder of Securities of such series made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be. With regard to any record date for action to be taken by the Holders of
one or more series of Securities, only the Holders of Securities of such series
on such date (or their duly designated proxies) shall be entitled to give or
take, or vote on, the relevant action.

                  (d) The ownership of Securities shall be proved by the
Security Register or by a certificate of the Security Registrar.


                                      -13-
   22
                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee, the
Company or the Guarantor in reliance thereon, whether or not notation of such
action is made upon such Security.

                  (f) Without limiting the foregoing, a Holder entitled
hereunder to give or take any action hereunder with regard to any particular
Security may do so with regard to all or any part of the principal amount of
such Security or by one or more duly appointed agents each of which may do so
pursuant to such appointment with regard to all or any different part of such
principal amount.

Section 105.      Notices, Etc., to Trustee, Company and Guarantor.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company or by the
         Guarantor shall be sufficient for every purpose hereunder if made,
         given, furnished or filed in writing to or with the Trustee at its
         Corporate Trust Office, Attention: Corporate Trust Department, or

                  (2) the Company or the Guarantor by the Trustee or by any
         Holder shall be sufficient for every purpose hereunder (unless
         otherwise herein expressly provided) if in writing and mailed, in the
         case of the Company, first-class postage prepaid, to the Company
         addressed to it at the address of its principal office specified in the
         first paragraph of this instrument, Attention: Treasurer, or at any
         other address previously furnished in writing to the Trustee by the
         Company, with a copy to the Guarantor, and, in the case of the
         Guarantor, first-class postage prepaid and addressed to it at the
         address of its principal office specified in the first paragraph of
         this instrument,


                                      -14-
   23
         Attention: Treasurer, or at any other address previously furnished in
         writing to the Trustee by the Guarantor, with a copy to the Company.

Section 106.  Notice to Holders; Waiver.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at its address as it appears in the Security
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice; provided,
however, that the Company, the Guarantor or the Trustee, upon a good faith
determination that mailing is in the circumstances impractical, may give such
notice by any other method which, in the reasonable belief of the Company or the
Guarantor or, in the case of the Trustee, of the Company, the Guarantor and the
Trustee, is likely to be received by the Holders. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

Section 107.  Conflict with Trust Indenture Act.

                  If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply


                                      -15-
   24
to this Indenture as so modified or to be excluded, as the case may be.

Section 108.  Effect of Headings and Table of Contents.

                  The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.

Section 109.  Successors and Assigns.

                  All covenants and agreements in this Indenture by the Company
or the Guarantor shall bind their successors and assigns, whether so expressed
or not.

Section 110.  Separability Clause.

                  In case any provision in this Indenture or in the Securities
or in the Guarantees shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

Section 111.  Benefits of Indenture.

                  Nothing in this Indenture or in the Securities or in the
Guarantees, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder and the Holders, any benefit or any legal
or equitable right, remedy or claim under this Indenture.

Section 112.  Governing Law.

                  This Indenture and the Securities and the Guarantees shall be
governed by and construed in accordance with the laws of the State of New York,
but without regard to principles of conflicts of laws.

Section 113.  Legal Holidays.

                  In any case where any Interest Payment Date, Redemption Date
or Stated Maturity of any Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of the Securities of any series which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the


                                      -16-
   25
same force and effect as if made on the Interest Payment Date or Redemption
Date, or at the Stated Maturity, provided that no interest shall accrue with
respect to such payment for the period from and after such Interest Payment
Date, Redemption Date or Stated Maturity, as the case may be, except that, if
such Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such Interest Payment Date or Redemption Date, or at
the Stated Maturity, as the case may be.

Section 114.      Personal Immunity from Liability for Incorporators,
                  Stockholders, Etc.

                  No recourse shall be had for the payment of the principal of
or premium, if any, or interest, if any, on any Security, or for any claim based
thereon, or otherwise in respect of any Security or of the Guarantees, or based
on or in respect of this Indenture or any indenture supplemental hereto, against
any incorporator, or against any past, present or future stockholder, director
or officer, as such, of the Company or of any successor corporation, or of the
Guarantor or of any successor corporation, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise, all such liability being expressly waived and released as
a condition of, and as consideration for, the execution of this Indenture and
the issue of the Securities and the Guarantees.

each series to be affected under the Indenture at any time by the Company, the
Guarantor and the Trustee with the consent of the Holders of a majority in
principal amount of the Securities at the time Outstanding of each series to be
affected. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such series,
to waive compliance by the Company or the Guarantor or both, with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange hereof or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter



                                      -24-


   33



or impair the obligation of the Company, which is absolute and unconditional, to
pay the principal of and any premium and interest on this Security at the times,
place and [rate-rates], and in the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registerable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

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

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

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

         The Indenture provides that the Company and the Guarantor, at the
Company's option, (a) will be discharged from any and all obligations in respect
of the Securities (except for certain obligations to register the transfer or
exchange of Securities, replace stolen, lost or mutilated Securities, maintain
paying agencies and hold moneys for

the Indenture, in each case if the Company or the Guarantor deposits, in trust,
with the Trustee money or U.S. Government Obligations (or Foreign Government
Obligations if the Securities are denominated in a foreign currency or
currencies) which through the payment of interest thereon and principal thereof
in accordance with their terms will provide money, in an amount sufficient to
pay all the principal (including any mandatory sinking fund payments) of, and
(premium, if any) and interest on, the Securities on the dates such payments are
due in accordance with the terms of such Securities and Guarantees, and certain
other conditions are satisfied.

         No recourse shall be had for the payment of the principal of (and
premium, if any) or interest on this Security, or for any claim based hereon, or
otherwise in respect hereof or of the Guarantee endorsed hereon, or based on or
in respect of the Indenture or any indenture supplemental thereto, against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Company or of any successor corporation, or of the Guarantor or
of any successor corporation, whether by virtue of any constitution, statute or
rule of law, or by the enforcement of any assessment or penalty or otherwise,
all such liability being, by the acceptance hereof and as part of the
consideration for the issue hereof, expressly waived and released.

shall have the meanings assigned to them in the Indenture.

                                    GUARANTEE
                                       OF
                                   AETNA INC.

         Aetna Inc., a Connecticut corporation (herein called the "Guarantor",
which term includes any successor corporation under the Indenture referred to in
the Security upon which this Guarantee is endorsed), for value received, hereby
unconditionally guarantees to the Holder of the Security upon which this
Guarantee is endorsed the due and punctual payment of the principal of, premium,
if any, and interest on said Security [and the due and punctual payment of the
sinking fund payments provided for herein], when and as the same shall become
due and payable, whether at the Stated Maturity or upon declaration of
acceleration, call for redemption or otherwise, according to the terms thereof
and of the Indenture referred to therein. In case of the failure of [Aetna Life
and Casualty Company] [Aetna Services, Inc.], a Connecticut corporation (herein
called the "Company", which term includes any successor corporation under such
Indenture) punctually to make any such payment of



                                      -27-


   36



principal, premium or interest [or sinking fund payment], the Guarantor hereby
agrees to pay or to cause any such payment to be made punctually when and as the
same shall become due and payable, whether at Stated Maturity or upon
declaration of acceleration, call for redemption or otherwise, and as if such
payment were made by the Company. The Guarantor hereby agrees that its
obligations hereunder shall be as if it were principal debtor and not merely
surety, and shall be absolute and unconditional, irrespective of, and shall be

Indenture, or the absence of any action to enforce the same, or any waiver,
modification, indulgence or consent granted to the Company with respect thereto,
by the Holder of said Security or by the Trustee, the recovery of any judgment
against the Company or any action to enforce the same or any other circumstance
that might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor; provided, however, that notwithstanding the foregoing, no
such waiver, modification or indulgence shall, without the consent of the
Guarantor, increase the principal amount of said Security or the interest rate
thereon or increase any premium payable upon redemption thereof. The Guarantor
hereby waives diligence, presentment, demand of payment, filing of claims with a
court in the event of bankruptcy of the Company, any right of set-off or to
counterclaim, any right to require a proceeding first against the Company,
protest or notice with respect to said Security or the indebtedness evidenced
thereby [or with respect to any sinking fund payment required under said
Security] and all demands whatsoever, and covenants that this Guarantee will not
be discharged except by payment in full of the principal of, and premium, if
any, and interest on said Security.

         The Guarantor shall be subrogated to all rights of the Holder against
the Company in respect of any amounts paid to such Holder by the Guarantor
pursuant to the provisions of this Guarantee; provided, however, that the
Guarantor shall not, without the consent of all Holders of all outstanding
Securities of this series issued under the Indenture, be entitled to enforce, or
to receive, any payments arising out of or based upon such right of subrogation
until the principal of, premium, if any, and interest then due and payable on
all Securities of the same series issued under the Indenture shall have been
irrevocably paid in full in accordance with the terms of such Securities.

         This Guarantee is a guarantee of payment when due and not of
collection. This Guarantee shall continue to be



                                      -28-


   37



effective, or be reinstated, as the case may be, in respect of said Security if
at any time payment, or any part thereof, of said Security is rescinded or must
otherwise be restored or returned by the Holder of said Security or any trustee
for said Holder upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Company or any other entity, or upon or as a result of the
appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for, the Company or any other entity or any substantial part of their
respective property, or otherwise, all as though such payments had not been
made.

         No reference herein to such Indenture and no provision of this
Guarantee or of such Indenture shall alter or impair the guarantee of the
Guarantor, which is absolute and unconditional, of the due and punctual payment
of the principal of, and premium, if any, and interest on the Security upon
which this Guarantee is endorsed at the times, place and rate, and in the cash
or currency prescribed herein.

         This Guarantee shall be governed by and construed in accordance with
the laws of the State of New York, but without regard to principles of conflicts
of laws.

         This Guarantee shall not be valid or become obligatory for any purpose
until the certificate of authentication on said Security shall have been
manually signed by or on behalf of the Trustee under such Indenture.

         All terms used in this Guarantee which are defined in such Indenture
shall have the meanings assigned to them in such Indenture.

   43




                  The seal of the Company or the Guarantor, as the case may be,
may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Securities. Securities bearing the
manual or facsimile signatures of individuals who were at any time the proper
officers of the Company or of the Guarantor shall bind the Company or the
Guarantor, as the case may be, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the authentication and delivery
of such Securities or did not hold such offices at the date of such Securities.
Minor typographical and other minor errors in the text of any Security or the
Guarantee endorsed thereon or minor defects in the seal or facsimile signature
on any Security or the Guarantee endorsed thereon shall not affect the validity
or enforceability of such Security or such Guaranty if such Security has been
duly authenticated and delivered by the Trustee.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company and having endorsed thereon Guarantees executed by the
Guarantor to the Trustee for authentication, together with a Company Order of
the Company for the authentication and delivery of such Securities, and the
Trustee in accordance with such Company Order shall authenticate and deliver
such Securities having such Guarantees endorsed thereon. If the form or terms of
the Securities of the series or the form of Guarantees endorsed thereon have
been established in or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities
and Guarantees endorsed thereon, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating,

                  (a) if the form or forms of such Securities and the applicable
         Guarantees have been established by or pursuant to Board Resolution as
         permitted by Section 201, that such form or forms have been established
         in conformity with the provisions of this Indenture;

                  (b) if the terms of such Securities and the applicable
         Guarantees have been established by or pursuant to Board Resolution as
         permitted by Section 301, that such terms have been established in



                                      -35-


   44



         conformity with the provisions of this Indenture;

                  (c) that such Securities, when authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights
         generally or the rights of creditors of insurance companies generally
         and to general equity principles; and

                  (d) that such Guarantees, when the Securities on which such
         Guarantees are endorsed are authenticated and delivered by the Trustee
         and issued by the Company in the manner and subject to any conditions
         specified in such Opinion of Counsel, will constitute valid and legally
         binding obligations of the Guarantor, enforceable in accordance with
         their terms, subject to bankruptcy, insolvency, reorganization and
         other laws of general applicability relating to or affecting the
         enforcement of creditors' rights and to general equity principles.

                  The Trustee shall have the right to decline to authenticate
and deliver any Securities under this Section if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken or if the Trustee
in good faith by its board of directors, executive committee, or a trust
committee of directors or responsible officers of the Trustee shall determine
that such action would expose the Trustee to personal liability to existing
Holders of Securities.

                  Notwithstanding the provisions of Section 301 and of the
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 301 or the Company Order and
Opinion of Counsel otherwise required pursuant to such preceding paragraph at or
prior to the time of authentication of each Security of such series if such



                                      -36-


   45



documents are delivered at or prior to the authentication upon original issuance
of the first Security of such series to be issued.

                  Each Security and the applicable Guarantee shall be dated the
date of its authentication.

                  No Security or Guarantee endorsed thereon shall be entitled to
any benefit under this Indenture or be valid or obligatory for any purpose
unless there appears on such Security a certificate of authentication
substantially in the form provided for herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and that such Security or Guarantee is entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such
Security and the Guarantee endorsed thereon shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

Section 304. Temporary Securities.

                  Pending the preparation of definitive Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities substantially of the tenor of the
definitive Securities in lieu of which they are issued and having endorsed
thereon Guarantees of the Guarantor substantially of the tenor of definitive
Guarantees, which Securities and Guarantees may be printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination
and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities or such Guarantees may
determine, as evidenced by their execution of such Securities and such
Guarantees.

                  If temporary Securities of any series are issued, the Company
will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or



                                      -37-


   46



agency of the Company in a Place of Payment for that series, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount and tenor which have endorsed thereon Guarantees duly executed
by the Guarantor. Until so exchanged the temporary Securities of any series
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series and tenor.

Section 305. Registration, Registration of Transfer and Exchange.

                  The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it or the Trustee may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities.
The Trustee is hereby appointed "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.

                  Upon surrender for registration of transfer of any Security of
any series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount and tenor which have endorsed thereon a Guarantee duly executed
by the Guarantor.

                  At the option of the Holder, Securities of any series may be
exchanged for other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor, each such
Security having endorsed thereon a Guarantee duly executed by the Guarantor upon
surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive.



                                      -38-


   47



                  All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company and the
Guarantor, evidencing the same debt, and entitled to the same benefits under
this Indenture, as the Securities surrendered upon such registration of transfer
or exchange.

                  Every Security presented or surrendered for registration of
transfer, exchange, redemption or payment shall (if so required by the Company
or the Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing.

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company or the Trustee may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906 or 1107 not
involving any transfer.

                  Unless otherwise required by the rules of any stock exchange
on which the Securities are listed or of any quotation system through which the
Securities are traded, neither the Company nor the Trustee shall be required (i)
to issue, register the transfer of or exchange Securities of any series during a
period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of Securities of that series selected for
redemption under Section 1103 and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange any Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

                  Notwithstanding any other provision in this Indenture, no
Global Security may be transferred to, or registered or exchanged for Securities
registered in the name of, any Person other than the Depositary for such Global
Security or any nominee thereof, and no such transfer may be registered, unless
(1) such Depositary (A) notifies the Company and the Trustee that it is
unwilling or unable to continue as Depositary for such Global Security or (B)
ceases to be a clearing agency registered under the Exchange Act, (2) the
Company executes and delivers to the Trustee a Company Order that such Global
Security shall be so transferable, registrable and exchangeable, and such



                                      -39-


   48



transfers shall be registrable, (3) there shall have occurred and be continuing
an Event of Default with respect to the Securities evidenced by such Global
Security or (4) there shall exist such other circumstances, if any, as have been
specified for this purpose as contemplated by Section 301. Notwithstanding any
other provision in this Indenture, a Global Security to which the restriction
set forth in the preceding sentence shall have ceased to apply may be
transferred only to, and may be registered and exchanged for Securities
registered only in the name or names of, such Person or Persons as the
Depositary for such Global Security shall have directed and no transfer thereof
other than such a transfer may be registered.

                  Every Security authenticated and delivered upon registration
of transfer of, or in exchange for or in lieu of, a Global Security to which the
restriction set forth in the first sentence of the preceding paragraph shall
apply, whether pursuant to this Section, Section 304, 306, 906 or 1107 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security.

Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

                  If there shall be delivered to the Company and the Trustee (i)
a mutilated Security, or (ii) evidence to their satisfaction of the destruction,
loss or theft of any Security and in either case such security or indemnity as
may be required by either of them to save each of them and any agent of either
of them harmless, then, in the absence of notice to the Company or the Trustee
that such Security has been acquired by a bona fide purchaser, the Company shall
execute and the Trustee shall authenticate and deliver, in lieu of any such
mutilated, destroyed, lost or stolen Security, a new Security of the same series
and of like tenor and principal amount having endorsed thereon a Guarantee duly
executed by the Guarantor, and bearing a number not contemporaneously
outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section, the
Company or the Trustee may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other



                                      -40-


   49



expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new Security of any series issued pursuant to this
Section in lieu of any destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company and the Guarantor,
whether or not the destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 307. Payment of Interest; Interest Rights Preserved.

                  Except as otherwise provided as contemplated by Section 301
with respect to any series of Securities, interest on any Security which is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest.

                  Any interest on any Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
Holder on the relevant Regular Record Date by virtue of having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be fixed in the following manner. The
         Company shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each Security of such series



                                      -41-


   50



         and the date of the proposed payment, and at the same time the Company
         shall deposit with the Trustee an amount of money equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as in this Clause provided. Thereupon the
         Trustee shall fix a Special Record Date for the payment of such
         Defaulted Interest which shall be not more than 15 days and not less
         than 10 days prior to the date of the proposed payment and not less
         than 15 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder of Securities of such series at its address as
         it appears in the Security Register, not less than 10 days prior to
         such Special Record Date. Notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor having been so
         mailed, such Defaulted Interest shall be paid to the Persons in whose
         names the Securities of such series (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         Clause (2).

                  (2) The Company may make payment of any Defaulted Interest on
         the Securities of any series in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Securities may be listed, and upon such notice as may be required
         by such exchange, if, after notice given by the Company to the Trustee
         of the proposed payment pursuant to this Clause, such manner of payment
         shall be deemed practicable by the Trustee.

   51




                  Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

Section 308. Persons Deemed Owners.

                  Prior to due presentment of a Security for registration of
transfer, the Company, the Guarantor, the Trustee and any agent of the Company,
the Guarantor or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of and any premium and (subject to Section 307) any interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Company, the Guarantor, the Trustee nor any agent of
the Company, the Guarantor or the Trustee shall be affected by notice to the
contrary.

                  No holder of any beneficial interest in any Global Security
held on its behalf by a Depositary shall have any rights under this Indenture
with respect to such Global Security, and such Depositary may be treated by the
Company, the Guarantor, the Trustee, and any agent of the Company, the Guarantor
or the Trustee as the owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall impair, as between a
Depositary and such holders of beneficial interests, the operation of customary
practices governing the exercise of the rights of the Depositary as Holder of
any Security.

Section 309. Cancellation.

                  All Securities surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and shall be promptly cancelled by it. The Company or the
Guarantor may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company or the
Guarantor may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Securities previously authenticated hereunder which the Company has not
issued and sold, and all Securities so delivered shall be promptly cancelled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities



                                      -43-


   52



cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order. Acquisition by the Company or the Guarantor of any
Security shall not operate as a redemption or satisfaction of the indebtedness
represented by such Security unless and until the same is delivered to the
Trustee for cancellation.

Section 310. Computation of Interest.

                  Except as otherwise specified as contemplated by Section 301
for Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months and, for any
period shorter than a full monthly period, shall be computed on the basis of the
actual number of days elapsed in such period.

                           Satisfaction and Discharge

Section 401. Satisfaction and Discharge of Indenture.

                  This Indenture shall upon Company Request cease to be of
further effect (except as to any surviving rights of registration of transfer or
exchange of Securities of a series herein expressly provided for) with respect
to Securities of any series and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture with respect to a series, when

                  (1) either

                  (A) all Securities of such series theretofore authenticated
         and delivered (other than (i) Securities which have been destroyed,
         lost or stolen and which have been replaced or paid as provided in
         Section 306 and (ii) Securities of such series for whose payment money
         has theretofore been deposited in trust or segregated and held in trust
         by the Company or the Guarantor and thereafter repaid to the Company or
         the Guarantor or discharged from such trust, as provided in Section
         1003) have been delivered to the Trustee for cancellation; or

   53
                  (B) all such Securities of such series not theretofore
         delivered to the Trustee for cancellation

                           (i) have become due and payable, or

                           (ii) will become due and payable at their Stated
                  Maturity within one year, or

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

         and the Company or the Guarantor, in the case of (i), (ii) or (iii)
         above, has deposited or caused to be deposited with the Trustee in
         trust for the purpose (A) money (either in United States dollars or
         such other currency or currency unit in which the Securities of any
         series may be payable) in an amount, or (B) U.S. Government Obligations
         (or Foreign Government Obligations if the Securities are denominated in
         a foreign currency or currencies) that through the scheduled payment of
         principal and interest in respect thereof in accordance with their
         terms will provide, not later than one day before the due date of any
         payment, money in an amount, or (C) a combination thereof, sufficient
         to pay and discharge the entire indebtedness on such Securities of such
         series not theretofore delivered to the Trustee for cancellation, for
         principal of (and premium, if any) and interest to the date of such
         deposit (in the case of Securities of such series which have become due
         and payable) or to the Stated Maturity or Redemption Date, as the case
         may be;

                  (2) the Company or the Guarantor has paid or caused to be paid
         all other sums payable hereunder 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 herein
         provided for relating to the satisfaction and discharge of this
         Indenture with respect to such series have been complied with.

                  In the event there are Securities of two or more series
outstanding hereunder, the Trustee shall be required to execute an instrument
acknowledging satisfaction and discharge of this Indenture only if requested to
do so with respect to Securities of a particular series as to which it is
Trustee and if the other conditions thereto are met. In the event that there are
two or more Trustees hereunder, then the effectiveness of any such instrument
shall be conditioned upon receipt of such instruments from all Trustees
hereunder.

                  Notwithstanding the satisfaction and discharge of this
Indenture with respect to a particular series, the obligations of the Company
and the Guarantor to the Trustee under Section 607, the obligations of the
Trustee to any Authenticating Agent under Section 614 and, if money shall have
been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this
Section, the obligations of the Trustee under Section 402 and the last paragraph
of Section 1003 shall survive until there are no Securities Outstanding with
respect to a particular series and the obligations of the Company, the Guarantor
and the Trustee with respect to all other series of Securities shall survive.

Section 402. Application of Trust Fund.

                  Subject to provisions of the last paragraph of Section 1003,
all amounts deposited with the Trustee pursuant to Section 401 shall be held in
trust and applied by it, in accordance with the provisions of the Securities and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company or the Guarantor acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal and any
premium and interest for whose payment such funds have been deposited with the
Trustee.

Section 501. Events of Default.

                  "Event of Default" whenever used with respect to Securities of
a series means any one of the following events and such other events as may be
established with respect to the Securities of such series as contemplated by
Section 301 hereof:

                  (1) Default in the payment of any instalment of interest upon
         any of the Securities of such series as and when the same shall become
         due and payable, and continuance of such default for a period of 30
         days; or

                  (2) Default in the payment of the principal of or premium, if
         any, on any of the Securities of such series as and when the same shall
         become due and payable either at maturity, upon redemption, by
         declaration or otherwise; or

                  (3) Default in the making of any sinking fund payment, whether
         mandatory or optional, as and when the same shall become due and
         payable by the terms of the Securities of such series; or

                  (4) Failure on the part of the Company or the Guarantor duly
         to observe or perform in any material respect any other of the
         covenants or agreements on the part of the Company or the Guarantor
         contained in this Indenture (other than those set forth exclusively in
         the terms of any other particular series of Securities established as
         contemplated by this Indenture for the benefit of such other series)
         and written notice of such failure, stating that such notice is a
         "Notice of Default" hereunder, and requiring the Company or the
         Guarantor, as the case may be, to remedy the same, shall have been
         given by registered or certified mail, return receipt requested, to the
         Company and the Guarantor by the Trustee, or to the Company, the
         Guarantor and the Trustee by the holders of at least 25% in aggregate
         principal amount of the Outstanding Securities of that series, and such
         failure shall have continued unremedied for a period of 90 days after
         the date

         of the Company's and the Guarantor's receipt of such Notice of Default;
         or

                  (5) An event of default, as defined in any indenture or
         instrument evidencing or under which the Company, the Guarantor or any
         Principal Subsidiary shall have outstanding indebtedness for borrowed
         money in a principal amount in excess of $50,000,000, shall happen and
         be continuing and such indebtedness shall have been accelerated so that
         the same shall be or become due and payable prior to the date on which
         the same would otherwise have become due and payable (other than
         acceleration of Non-Recourse Debt which does not exceed in the
         aggregate 4% of the Guarantor's total shareholders' equity, as set
         forth in the most recently published audited consolidated balance sheet
         of the Guarantor) or the Company, the Guarantor or any Principal

         Guarantor's total shareholders' equity as set forth in the most
         recently published audited consolidated balance sheet of the
         Guarantor), and such acceleration or default at maturity shall not be
         waived, rescinded or annulled within 30 days after written notice
         thereof, stating that such notice is a "Notice of Default" hereunder,

         (if such event be known to it), or to the Company, the Guarantor and
         the Trustee by the holders of at least 25% in aggregate principal
         amount of the Outstanding Securities of that series; provided, however,
         that if such acceleration under such indenture or instrument or default
         at maturity shall be remedied or cured by the Company, the Guarantor or
         Principal Subsidiary, or waived, rescinded or annulled by the requisite
         holders of such indebtedness, then the Event of 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 Sections 601 and 602, the Trustee shall
         not be charged with knowledge of any such default unless



                                      -48-


   57



         written notice thereof shall have been given to the Trustee by the
         Company or the Guarantor, as the case may be, by the holder of any such
         indebtedness or an agent of the holder of any such indebtedness, by the
         trustee then acting under any such indenture or other instrument under
         which such default shall have occurred, or by the holders of at least
         25% in aggregate principal amount of the Outstanding Securities of that
         series; or

                  (6) A decree or order by a court having jurisdiction in the
         premises shall have been entered adjudging the Company or the Guarantor
         a bankrupt or insolvent, or approving as properly filed a petition
         seeking reorganization, arrangement, adjustment or composition of the
         Company or the Guarantor under any applicable Federal or State
         bankruptcy or similar law, and such decree or order shall have
         continued undischarged and unstayed for a period of 90 days; or a
         decree or order of a court having jurisdiction in the premises for the
         appointment of a receiver, liquidator, trustee, assignee, sequestrator
         or similar official in bankruptcy or insolvency of the Company or the
         Guarantor or of all or substantially all of the Company's or the
         Guarantor's property, or for the winding up or liquidation of the
         Company's or the Guarantor's affairs, shall have been entered, and such
         decree or order shall have continued undischarged and unstayed for a
         period of 90 days; or

                  (7) The Company or the Guarantor shall institute proceedings
         to be adjudicated a voluntary bankrupt, or shall consent to the filing
         of a bankruptcy proceeding against it, or shall file a petition or
         answer or consent seeking reorganization, arrangement, adjustment or
         composition under any applicable Federal or State bankruptcy or similar
         law, or shall consent to the filing of any such petition, or shall
         consent to the appointment of a receiver, liquidator, trustee,
         assignee, sequestrator or similar official in bankruptcy or insolvency
         of the Company or the Guarantor or of all or substantially all of the
         Company's or the Guarantor's property, or shall make an assignment for
         the benefit of creditors, or either the Company or the Guarantor shall
         admit in writing



                                      -49-


   58



         its inability to pay its debts generally as they become due and its
         willingness to be adjudged a bankrupt, or corporate action shall be
         taken by the Company or the Guarantor in furtherance of any of the
         aforesaid purposes.

                  Upon receipt by the Trustee of any Notice of Default pursuant
to this Section 501 with respect to Securities of any series, a record date
shall automatically and without any other action by any Person be set for the
purpose of determining the holders of Outstanding Securities of such series
entitled to join in such Notice of Default, which record date shall be the close
of business on the day the Trustee receives such Notice of Default. The Holders
of Outstanding Securities of such series on such record date (or their duly
appointed agents), and only such Persons, shall be entitled to join in such
Notice of Default, whether or not such Holders remain Holders after such record
date; provided that, unless such Notice of Default shall have become effective
by virtue of Holders of at least 25% in principal amount of Outstanding
Securities of such series on such record date (or their duly appointed agents)
having joined therein on or prior to the 90th day after such record date, such
Notice of Default shall automatically and without any action by any Person be
cancelled and of no further effect. Nothing in this paragraph shall prevent a
Holder (or a duly appointed agent thereof) from giving, before or after the
expiration of such 90-day period, a Notice of Default contrary to or different
from, or, after the expiration of such period, identical to, a Notice of Default
that has been cancelled pursuant to the proviso to the preceding sentence, in
which event a new record date in respect thereof shall be set pursuant to this
paragraph.

Section 502. Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company and the Guarantor (and to the
Trustee if given by Holders), and upon any such declaration



                                      -50-


   59



such principal amount (or specified amount) and all accrued interest thereon
shall become immediately due and payable.

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

                  (1) the Company or the Guarantor has paid or deposited with
         the Trustee a sum sufficient to pay

                           (A) all overdue interest on all Securities of that
                  series,

                           (B) the principal of (and premium, if any, on) any
                  Securities of that series which have become due otherwise than
                  by such declaration of acceleration and any interest thereon
                  at the rate or rates prescribed therefor in such Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate or rates
                  prescribed therefor in such Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel except such costs and expenses as are a result of
                  negligence or bad faith on the part of the Trustee;

         and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of and interest, if
         any, on the Securities of that series which have become due solely by
         such



                                      -51-


   60



         declaration of acceleration, have been cured
         or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                  Upon receipt by the Trustee of any declaration of
acceleration, or any rescission and annulment of any such declaration, pursuant
to this Section 502 with respect to Securities of any series, a record date
shall automatically and without any other action by any Person be set for the
purpose of determining the Holders of Outstanding Securities of such series
entitled to join in such declaration, or rescission and annulment, as the case
may be, which record date shall be the close of business on the day the Trustee
receives such declaration, or rescission and annulment, as the case may be. The
Holders of Outstanding Securities of such series on such record date (or their
duly appointed agents), and only such Persons, shall be entitled to join in such
declaration, or rescission and annulment, as the case may be, whether or not
such Holders remain Holders after such record date; provided that, unless such
declaration, or rescission and annulment, as the case may be, shall have become
effective by virtue of Holders of at least 25%, in the case of any declaration
of acceleration, or a majority, in the case of any rescission or annulment, in
principal amount of Outstanding Securities of such series on such record date
(or their duly appointed agents) having joined therein on or prior to the 90th
day after such record date, such declaration, or rescission and annulment, as
the case may be, shall automatically and without any action by any Person be
cancelled and of no further effect. Nothing in this paragraph shall prevent a
Holder (or a duly appointed agent thereof) from giving, before or after the
expiration of such 90-day period, a declaration of acceleration, or a rescission
and annulment of any such declaration, contrary to or different from, or, after
the expiration of such period, identical to, a declaration, or rescission and
annulment, as the case may be, that has been cancelled pursuant to the proviso
to the preceding sentence, in which event a new record date in respect thereof
shall be set pursuant to this paragraph.

Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

                  The Company covenants that if

                  (1) default is made in the payment of any interest on any
        Security when such



                                      -52-


   61



         interest becomes due and payable and such
         default continues for a period of 30 days, or

                  (2)  default is made in the payment of
         the principal of (or premium, if any, on) any
         Security at the Maturity thereof,

the Company will, upon written demand of the Trustee, pay to it, for the benefit
of the Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, 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 except such costs and expenses, as are a
result of negligence or bad faith on the part of the Trustee. Until such demand
is made by the Trustee, the Company may pay the principal of and premium, if
any, and interest, if any, on the Securities of any series to the Holders
thereof, whether or not the Securities of such series are overdue.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company, the Guarantor or any other obligor upon
such Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company, the Guarantor or any
other obligor upon such Securities, wherever situated.

                  If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.



                                      -53-

Section 504.  Trustee May File Proofs of Claim.

                  In case of any judicial proceeding relative to the Company,
the Guarantor or any other obligor upon the Securities or the property of the
Company, the Guarantor or such other obligor or their creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized
                  (i) to file and prove a claim for the whole amount of
         principal (and premium, if any) and interest owing and unpaid in
         respect of the Securities in accordance with the terms thereof and to
         file such other papers or documents as may be necessary or advisable in
         order to have the claims of the Trustee (including any claim for the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel) and of the Holders allowed in such
         judicial proceeding, and

                  (ii)     to collect and receive any moneys or other
         property payable or deliverable on any such claims and
         to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official 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 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 607 except such costs and expenses, as are
a result of negligence or bad faith on the part of the Trustee.

                  No provision of this Indenture 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;
provided, however, that the Trustee may, on behalf of the Holders, vote for the
election of a trustee in bankruptcy or similar official and be a member of a
creditors' or other similar committee.

Section 505.      Trustee May Enforce Claims Without
                  Possession of Securities.

                  All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel except such
costs and expenses, as are a result of negligence or bad faith on the part of
the Trustee, be for the ratable benefit of the Holders of the Securities in
respect of which such judgment has been recovered.

Section 506.      Application of Money Collected.

                  Any money collected by the Trustee pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
or any premium or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
         Section 607;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of and any premium and interest on the Securities in respect
         of which or for the benefit of which such money has been collected,
         ratably, without preference or priority of any kind, according to the
         amounts due and payable on such Securities for principal and any
         premium and interest, respectively; and

                  THIRD: To the payment of the remainder, if any, to the Company
         or any other Person lawfully entitled thereto.

Section 507.      Limitation on Suits.

                  No Holder of any Security of any series shall have any right
to institute any proceeding, judicial or otherwise, with respect to this
Indenture or for the


                                      -55-
   64
appointment of a receiver or trustee, or for any other remedy hereunder, unless

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of that series shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         indemnity reasonably satisfactory in form and substance to the Trustee
         against the costs, expenses and liabilities to be incurred in
         compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

Section 508.      Unconditional Right of Holders to Receive
                  Principal, Premium and Interest.

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and
(subject to


                                      -56-
   65
Section 307) any interest on such Security on the Stated Maturity or Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment, and such
rights shall not be impaired without the consent of such Holder.

Section 509.      Restoration of Rights and Remedies.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Guarantor, the Trustee and
the Holders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

Section 510.      Rights and Remedies Cumulative.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 511.      Delay or Omission Not Waiver.

                  No delay or omission of the Trustee or of any Holder of any
Securities to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Subject to Section 507, every right and
remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.


                                      -57-
   66
Section 512.      Control by Holders.

                  The Holders of a majority in principal amount of the
Outstanding Securities of any series shall have the right to 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 the Trustee, with respect
to the Securities of such series, provided that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

                  Upon receipt by the Trustee of any such direction with respect
to Securities of any series, a record date shall be set for determining the
Holders of Outstanding Securities of such series entitled to join in such
direction, which record date shall be the close of business on the day the
Trustee receives such direction. The Holders of Outstanding Securities of such
series on such record date (or their duly appointed agents), and only such
Persons, shall be entitled to join in such direction, whether or not such
Holders remain Holders after such record date; provided that, unless such
direction shall have become effective by virtue of Holders of at least a
majority in principal amount of Outstanding Securities of such series on such
record date (or their duly appointed agents) having joined therein on or prior
to the 90th day after such record date, such direction shall automatically and
without any action by any Person be cancelled and of no further effect. Nothing
in this paragraph shall prevent a Holder (or a duly appointed agent thereof)
from giving, before or after the expiration of such 90-day period, a direction
contrary to or different from, or, after the expiration of such period,
identical to, a direction that has been cancelled pursuant to the proviso to the
preceding sentence, in which event a new record date in respect thereof shall be
set pursuant to this paragraph.

Section 513.      Waiver of Past Defaults.

                  The Holders of not less than a majority in principal amount of
the Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default


                                      -58-
   67
                  (1) in the payment of the principal of or any premium or
         interest on any Security of such series, or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

                  With respect to any series of Securities, the Company or the
Guarantor may, but shall not be obligated to, establish a record date for the
purpose of determining the Persons entitled to waive any past default hereunder.
If a record date is fixed, the Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to waive any
default hereunder, whether or not such Holders remain Holders after such record
date; provided, however, that unless such Holders of not less than a majority in
principal amount of the Outstanding Securities of such series shall have waived
such default prior to the date which is 90 days after such record date, any such
waiver previously given shall automatically and without further action by any
Holder be cancelled and of no effect.

                  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 514.      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,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided
in the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or the Guarantor.

Section 601.      Certain Duties and Responsibilities.

                  The duties and responsibilities of the Trustee shall be as
provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision
of this Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection to
the Trustee shall be subject to the provisions of this Section.

Section 602.      Notice of Defaults.

                  If a default occurs hereunder with respect to Securities of
any series, the Trustee shall give the Holders of Securities of such series
notice of such default as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified in
Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

Section 603.      Certain Rights of Trustee.

                  Subject to the provisions of Section 601:

                  (a) the Trustee may rely and shall be protected in acting or

         of the Company or the Guarantor may be sufficiently evidenced by a
         Board Resolution;

                  (c) whenever in the administration of this Indenture the

         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

                  (d) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and

         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee security or indemnity
         reasonably satisfactory in form and substance to the Trustee against
         the costs, expenses and liabilities which might be incurred by it in
         compliance with such request or direction;

         notice, request, direction, consent, order, bond, debenture, note,
         other evidence of indebtedness or other paper or document, but the
         Trustee, in its discretion, may make such further inquiry or
         investigation into such facts or matters as it may see fit, and, if the
         Trustee shall determine to make such further inquiry or investigation,
         it

                                      -61-
   70
         shall upon reasonable notice to the Company and the Guarantor be
         entitled to examine the books, records and premises of the Company and
         the Guarantor, personally or by agent or attorney at a time and place
         acceptable to the Company or the Guarantor, as the case may be; and

                  (g) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder.

Section 604.      Not Responsible for Recitals or
                  Issuance of Securities.

                  The recitals contained herein and in the Securities, except
the Trustee's certificates of authentication, shall be taken as the statements
of the Company or the Guarantor, as the case may be, and the Trustee or any
Authenticating Agent assumes no responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities or of the Guarantees. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

Section 605.      May Hold Securities.

                  The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company or the Guarantor, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 608 and 613, may otherwise deal with the Company or the
Guarantor with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

Section 606.      Money Held in Trust.

                  Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as

                                      -62-
   71
otherwise agreed with the Company or the Guarantor, as the case may be.

Section 607.      Compensation and Reimbursement.

                  The Company and the Guarantor agree

                  (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee upon its written request for all reasonable
         expenses, disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation, and reasonable expenses and disbursements of
         its agents and outside counsel), except any such expense, disbursement
         or advance as may be attributable to its negligence or bad faith; and

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense incurred without negligence or
         bad faith on its part, arising out of or in connection with the
         acceptance or administration of the trust or trusts hereunder,
         including the reasonable costs and expenses of defending itself against
         any claim or liability in connection with the exercise or performance
         of any of its powers or duties hereunder.

Section 608.      Disqualification; Conflicting
                  Interests.

                  If the Trustee has or shall acquire a conflicting interest

eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture.

Section 609.      Corporate Trustee Required;
                  Eligibility.

                  There shall at all times be a Trustee hereunder which shall be
a Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and surplus of at least $50,000,000 or is a subsidiary of
a corporation which shall be a Person that has a combined capital and surplus of
at least $50,000,000 and which unconditionally guarantees the obligations of the
Trustee hereunder. If such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Person shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

Section 610.      Resignation and Removal;
                  Appointment of Successor.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 611.

                  (b) The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the Company
and the Guarantor. If the instrument of acceptance by a successor Trustee
required by Section 611 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

                  (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company and the Guarantor.

                  (d)  If at any time:


                                      -64-
   73
                  (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Company or the Guarantor or by any
         Holder who has been a bona fide Holder of a Security for at least six
         months, or

                  (2) the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the Company
         or the Guarantor or by any such Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of itself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, with respect to the Securities of one or more series, the Company, by
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series) and shall comply with
the applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the Guarantor
and the retiring Trustee, the successor Trustee so appointed shall, forthwith
upon its acceptance of such appointment in accordance with the applicable
requirements

                                      -65-
   74
of Section 611, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of itself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to all Holders of Securities of such series in the manner provided in Section
106. Each notice shall include the name of the successor Trustee with respect to
the Securities of such series and the address of its Corporate Trust Office.

Section 611.      Acceptance of Appointment by
                  Successor.

                  (a) In case of the appointment hereunder of a successor
Trustee with respect to all Securities, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company, to the
Guarantor and to the retiring Trustee an instrument accepting such appointment,
and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Company, the Guarantor or
the successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

                  (b) In case of the appointment hereunder of a successor
Trustee with respect to the Securities of one or more (but not all) series, the
Company, the Guarantor, the retiring Trustee and each successor Trustee with
respect to the Securities of such series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee

                                      -66-
   75
shall accept such appointment and which (1) shall contain such provisions as
shall be necessary or desirable to transfer the rights, powers, trust and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates, (2) if the retiring
Trustee is not retiring with respect to all Securities, shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (3) shall add
to or change any of the provisions of this Indenture as shall be necessary to
provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustee co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any other
such Trustee; and upon the execution and delivery of such supplemental indenture
the resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on
request of the Company and the Guarantor or any successor Trustee, such retiring
Trustee shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates.

                  (c) Upon request of any such successor Trustee, the Company
and the Guarantor shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts referred to in paragraphs (a) and (b) of this Section, as the
case may be.

                  (d) No successor shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

Section 612.      Merger, Conversion, Consolidation or
                  Succession to Business.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. 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 with the same
effect as if such successor Trustee had itself authenticated such Securities.

Section 613.      Preferential Collection of Claims
                  Against Company or Guarantor.

                  If and when the Trustee shall be or become a creditor of the
Company, the Guarantor or any other obligor upon the Securities, the Trustee
shall be subject to the provisions of the Trust Indenture Act regarding the
collection of claims against the Company, the Guarantor or any such other
obligor.

Section 614.      Appointment of Authenticating Agent.

                  The Trustee may with the consent of the Company appoint an
Authenticating Agent or Agents with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of such series issued upon original issue and upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section
306, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the


                                      -68-
   77
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee or the
Company may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company or
the Trustee, as the case may be. Upon receiving such a notice of resignation or
upon such a termination, or in case at any time such Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, the
Trustee may appoint a successor Authenticating Agent which shall be acceptable
to the Company and shall mail written notice of such appointment by first-class
mail, postage prepaid, to all Holders of Securities of the series with respect
to which such Authenticating Agent will serve, as their names and addresses
appear in the Security Register. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as


                                      -69-
   78
if originally named as an Authenticating Agent. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

                  If an appointment with respect to one or more series is made
pursuant to this Section, the Securities of such series may have endorsed
thereon, in addition to the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

                  This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                                                       ........................,
                                                                      As Trustee

reasonably practicable, the names and addresses of Holders contained in the most

against the assuming corporation in accordance with their terms subject to (a)
bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium and
other similar laws now or hereafter in effect relating to or affecting creditors
rights generally and the rights of creditors of insurance companies generally
and (b) general principles of equity (regardless of whether considered in a

with their terms subject to (a) bankruptcy, insolvency, reorganization,
fraudulent transfer, moratorium and other similar laws now or hereafter in
effect relating to or affecting creditors rights generally and the rights of

shall succeed to, and be substituted for, and may exercise every right and power
of, the Company under this Indenture with the same effect as if the Guarantor or
such Subsidiary, as the case may be, had been named as the "Company" herein, and
the Person named as the "Company" in the first paragraph of this instrument or
any successor Person which shall theretofore have become such in the manner
prescribed in this Article shall be released from its liability as obligor upon
the Securities.

         provision herein which may be inconsistent with any other provision
         herein, or to make any other provisions with respect to matters or
         questions arising under this Indenture, provided that such action
         pursuant to this clause (9) shall not adversely affect the interests of

thereby,

                                      -77-

Indenture of the Holders of Securities of any other series.

                  It shall not be necessary for any Act of Holders under this

execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as

Guarantees endorsed thereon may be executed by the Guarantor and such Securities
may be authenticated and delivered by the Trustee in exchange for Outstanding

may be, if there is obtained the prior consent or waiver of the holders of at
least a majority in aggregate principal amount of the then Outstanding
Securities of such series.

Section 1001. Payment of Principal, Premium and Interest.

                  The Company covenants and agrees for the benefit of each
series of Securities that it will duly and punctually pay or cause to be paid
the principal of and any premium and interest on the Securities of that series
in

                                      -80-
   89
accordance with the terms of the Securities and this Indenture.

Section 1002. Maintenance of Office or Agency by Company
              and Guarantor.

                  (a) So long as any Securities are Outstanding, the Company
will maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of
transfer or exchange, and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

                  The Company may also from time to time designate one or more
other offices or agencies where the Securities of one or more series 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 each Place of Payment for Securities of any series for
such purposes. The Company will 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.

                  (b) So long as any Securities are Outstanding, the Guarantor
will maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for
payment under the Guarantees endorsed thereon and where notices and demands to
or upon the Guarantor in respect of the Guarantees endorsed on the Securities of
that series and this Indenture may be served. The Guarantor will give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Guarantor shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Guarantor

                                      -81-
   90
hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

                  The Guarantor may also from time to time designate one or more
other offices or agencies where the Securities of one or more series may be
presented or surrendered for such purpose or where such notices or demands may
be served and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Guarantor of its obligation to maintain an office or agency in each Place of
Payment for Securities of any series for such purposes. The Guarantor will 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.

Section 1003. Money for Securities Payments to
              Be Held in Trust.

                  If the Company or the Guarantor shall at any time act as its
own Paying Agent with respect to any series of Securities, it will, on or before
each due date of the principal of or any premium or interest on any of the
Securities of that series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal and any premium
and interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee of
its action or failure so to act.

                  Whenever the Company shall have one or more Paying Agents for
any series of Securities, it will, prior to each due date of the principal of or
any premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

                  The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (i) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) during the continuance of any default by the Company (or any other obligor
upon the Securities of that series) in the making of any payment in respect of
the Securities of that series, and upon the written request of the Trustee,
forthwith pay to

                                      -82-
   91
the Trustee all sums held in trust by such Paying Agent for payment in respect
of the Securities of that series.

                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company or the Guarantor, in trust for the payment of the
principal of or any premium or interest on any Security of any series and
remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the Company or the Guarantor, as the
case may be, on Company Request, or (if then held by the Company or the
Guarantor) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company or
the Guarantor for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
or the Guarantor as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, the City of
New York, 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
publication, any unclaimed balance of such money then remaining will be repaid
to the Company or the Guarantor, as the case may be.

Section 1004. Statement by Officers as to Default.

                  The Company and the Guarantor will each deliver to the Trustee
within 120 days after the end of each fiscal year of the Guarantor ending after
the date hereof, a certificate signed by the Company's or the Guarantor's, as
the case may be, principal executive officer, principal financial officer or
principal accounting officer stating whether or not to the best knowledge of the
signer thereof the Company or the Guarantor, as the case may be, is in
compliance with all terms, conditions and covenants of this Indenture (without
regard to any period of grace or

                                      -83-
   92
requirement of notice provided hereunder) and if the signer has obtained
knowledge of any continuing default by the Company or the Guarantor in the
performance, observation or fulfillment of any such term, condition or covenant,
specifying each such default and the nature thereof.

Section 1005. Limitations on Liens on Common Stock of Principal Subsidiaries.

                  As long as any of the Securities remains outstanding, the
Guarantor will not, and will not permit any Principal Subsidiary to, issue,
assume, incur or guarantee any indebtedness for borrowed money secured by a
mortgage, pledge, lien or other encumbrance, directly or indirectly, on any of
the Common Stock of a Principal Subsidiary, which Common Stock is owned by the
Guarantor, by the Company or by any Principal Subsidiary, unless the obligations
of the Company under the Securities and, if the Company or the Guarantor so
elects, any other indebtedness of the Company or the Guarantor ranking on a
parity with or prior to the Securities or the Guarantor's obligations under the
Guarantees, as the case may be, shall be secured equally and ratably with, or
prior to, such secured indebtedness for borrowed money so long as it is
outstanding and is so secured.

                                 ARTICLE ELEVEN

                            Redemption of Securities

Section 1101. Applicability of Article.

                  Securities of any series which are redeemable before their
Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 301 for Securities of any
series) in accordance with this Article.

Section 1102. Election to Redeem; Notice to Trustee.

                  In case of any redemption at the election of the Company of
less than all the Securities of any series, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of
the principal amount of Securities of such series to be redeemed and, if
applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall

                                      -84-
   93
furnish the Trustee with an Officers' Certificate evidencing compliance with
such restriction.

Section 1103. Selection by Trustee of Securities to Be Redeemed.

                  If less than all the Securities of any series are to be
redeemed (unless all of the Securities of such series and of a specified tenor
are to be redeemed), the particular Securities to be redeemed shall be selected
not more than 45 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and which may provide
for the selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Securities of such series of a denomination larger than
the minimum authorized denomination for Securities of that series. If less than
all of the Securities of such series and of a specified tenor are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 45 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series and specified tenor not previously called for
redemption in accordance with the preceding sentence.

                  The Trustee shall promptly notify the Company in writing of
the Securities selected for redemption and, in the case of any Securities
selected for partial redemption, the principal amount thereof to be redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in
part, to the portion of the principal amount of such Securities which has been
or is to be redeemed.

Section 1104.  Notice of Redemption.

                  Notice of redemption shall be given by first-class mail,
postage prepaid, mailed not less than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of Securities to be redeemed, at its address
appearing in the Security Register.

                  All notices of redemption shall state:

                  (1)  the Redemption Date,

                  (2)  the Redemption Price,

                                      -85-
   94
                  (3) if less than all the Outstanding Securities of any series
         are to be redeemed, the identification (and, in the case of partial
         redemption of any Securities, the principal amounts) of the particular
         Securities to be redeemed,

                  (4) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security to be redeemed and, if
         applicable, that interest thereon will cease to accrue on and after
         said date,

                  (5) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and

                  (6) that the redemption is for a sinking fund, if such is the
         case.

                  Notice of redemption of Securities to be redeemed at the
election of the Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.

Section 1105.  Deposit of Redemption Price.

                  Prior to any Redemption Date, the Company shall deposit with
the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

Section 1106.  Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest to the Redemption Date; provided, however, that, unless
otherwise specified as contemplated by Section 301, installments of interest
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more

                                      -86-
   95
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal and any premium shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

Section 1107. Securities Redeemed in Part.

                  Any Security which is to be redeemed only in part shall be
surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Security or Securities of the same series and of
like tenor, of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered.

                                 ARTICLE TWELVE

                       Defeasance and Covenant Defeasance

Section 1201. Company's Option to Effect Defeasance or Covenant Defeasance.

                  The Company may elect, at any time, to have either Section
1202 or Section 1203 applied to the Outstanding Securities of any series and the
Guarantees endorsed thereon, upon compliance with the conditions set forth below
in this Article Twelve.

Section 1202. Defeasance and Discharge.

                  Upon the Company's exercise of the option provided in Section
1201 to have this Section 1202 applied to the Outstanding Securities of any
series and the Guarantees endorsed thereon, the Company and the Guarantor shall
each be deemed to have been discharged from its obligations with respect to the
Outstanding Securities of such series and the Guarantees endorsed thereon as
provided in this Section on and after the date the conditions set forth in
Section 1204 are satisfied (hereinafter called "Defeasance"). For this purpose,
such Defeasance means that the Company and the

                                      -87-
   96
Guarantor shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities of such series and the Guarantees
endorsed thereon and to have satisfied all their other obligations under the
Securities of such series, the Guarantees endorsed thereon and this Indenture
insofar as the Securities of such series and the Guarantees endorsed thereon are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), subject to the following which shall
survive until otherwise terminated or discharged hereunder: (1) the rights of
Holders of Securities of such series to receive, solely from the trust fund
described in Section 1204 and as more fully set forth in such Section, payments
in respect of the principal of and any premium and interest on such Securities
of such series when payments are due, (2) the Company's or the Guarantor's
obligations, as the case may be, with respect to the Securities of such series
under Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts,
duties and immunities of the Trustee hereunder, including, without limitation,
its rights under Section 607 and (4) this Article Twelve. Subject to compliance
with this Article Twelve, the Company may exercise its option provided in
Section 1201 to have this Section 1202 applied to the Outstanding Securities of
any series and the Guarantees endorsed thereon notwithstanding the prior
exercise of its option provided in Section 1201 to have Section 1203 applied to
the Outstanding Securities of such series and the Guarantees endorsed thereon.

Section 1203. Covenant Defeasance.

                  Upon the Company's exercise of the option provided in Section
1201 to have this Section 1203 applied to the Outstanding Securities of any
series and the Guarantees endorsed thereon, (1) the Guarantor shall be released
from its obligations under Section 1005 and the Company and the Guarantor shall
be released from their obligations under Section 801 and (2) the occurrence of
any event specified in Sections 501(3), 501(4) (with respect to Section 1005 and
Section 801) and 501(5) shall be deemed not to be or result in an Event of
Default, in each case with respect to the Outstanding Securities of such series
as provided in this Section on and after the date the conditions set forth in
Section 1204 are satisfied (hereinafter called "Covenant Defeasance"). For this
purpose, such Covenant Defeasance means that the Company and the Guarantor may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Section 501(4)), whether directly or indirectly by
reason of any reference elsewhere herein to any such Section or by reason

                                      -88-
   97
of any reference in any such Section to any other provision herein or in any
other document, but the remainder of this Indenture and the Securities of such
series shall be unaffected thereby.

Section 1204. Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of either
Section 1202 or Section 1203 to the Outstanding Securities of any series:

                  (1) The Company or the Guarantor shall irrevocably have

         agrees to comply with the provisions of this Article Twelve applicable
         to it) as trust funds in trust for the purpose of making the following

         a nationally recognized firm of independent public accountants
         expressed in a written certification thereof delivered to the Trustee,
         to pay and discharge, and which shall be applied by the Trustee (or any
         such other qualifying trustee) to pay and discharge, the principal of

         the United States of America, which, in either case (i) or (ii), is not
         callable or redeemable at the option of the issuer thereof, and (y) any

         Government Obligation specified in Clause (x) and held by such
         custodian for the account of the holder of such depositary receipt, or
         with respect to any specific payment of principal of or interest on any
         such U.S. Government Obligation, provided that (except as required by
         law) such custodian is not authorized to make any deduction from the
         amount payable to the Holder of such depositary receipt from any amount
         received by the custodian in respect of the U.S. Government Obligation

         any security that is (i) a direct obligation of the government that
         issued such currency for the payment of which full faith and credit of
         such government is pledged or (ii) an obligation of a Person controlled

         Section 3(a)(2) of the Securities Act of 1933, as amended) as custodian

         such custodian for the account of the holder of such depositary
         receipt, or with respect to any specific payment of principal of or
         interest on any such Foreign Government Obligation, provided that
         (except as required by law) such custodian is not authorized to make

         the Holders of the Outstanding Securities of such series will not
         recognize gain or loss for Federal income tax purposes as a result of
         the deposit, Defeasance and discharge to be effected with respect to
         the Securities of such series and will be subject to Federal income tax
         on the same amount, in the same manner and at the same times as would
         be the case if such deposit, Defeasance and discharge were not to
         occur.

                  (3) In the case of an election under Section 1203, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holder of the Outstanding Securities of such series will not

                  (4) The Company shall have delivered to the Trustee an
         Officers' Certificate to the effect that the Securities of such series,
         if then listed on any securities exchange, will not be delisted as a
         result of such deposit.

                  (5) No Event of Default or event that (after notice or lapse
         of time or both) would become an Event of Default shall have occurred
         and be continuing at the time of such deposit or, with regard to any
         Event of Default or any such event specified in Sections 501(6) and
         501(7), at any time on or prior to the 90th day after the date of such
         deposit (it being understood that this condition shall not be deemed
         satisfied until after such 90th day).

                  (6) The Company shall have delivered to the Trustee an
         Officer's Certificate and an Opinion of Counsel, each stating that all
         conditions precedent with respect to such Defeasance or Covenant
         Defeasance have been complied with.

                  (7)      Such Defeasance or Covenant Defeasance shall
         not result in the trust arising from such deposit

                                      -91-
   100
         constituting an investment company within the meaning of the Investment
         Company Act of 1940, as amended, unless such trust shall be qualified
         under such Act or exempt from regulation thereunder.

Section 1205. Deposited Money and U.S. Government Obligations or Foreign
              Government Obligations to be Held In Trust; Other Miscellaneous
              Provisions.

                  Subject to the provisions of the last paragraph of Section
1003, all money and U.S. Government Obligations or Foreign Government
Obligations (including the proceeds thereof) deposited with the Trustee or other
qualifying trustee (solely for purposes of this Section and Section 1206, the
Trustee and any such other trustee are referred to collectively as the
"Trustee") pursuant to Section 1204 in respect of the Securities of any series
shall be held in trust and applied by the Trustee, in accordance with the
provisions of the Securities of such series and this Indenture, to the payment,
either directly or through any such Paying Agent (including the Company or the
Guarantor acting as its own Paying Agent) as the Trustee may determine, to the
Holders of Securities of such series, of all sums due and to become due thereon
in respect of principal and any premium and interest, but money so held in trust
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 or Foreign Government Obligations deposited pursuant to Section 1204
or the principal and interest received in respect thereof other than any such
tax, fee or other charge that by law is for the account of the Holders of
Outstanding Securities.

                  Anything in this Article Twelve to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company or the
Guarantor, as the case may be, from time to time upon Company Request any money
or U.S. Government Obligations or Foreign Government Obligations held by it as
provided in Section 1204 with respect to Securities of any series that, 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 that would then be required to be deposited to
effect an equivalent Defeasance or Covenant Defeasance with respect to the
Securities of such series and the Guarantees endorsed thereon.

Section 1206. Reinstatement.

                                      -92-
   101
                  If the Trustee or the Paying Agent is unable to apply any
money in accordance with this Article Twelve with respect to the Securities of
any series by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's and the Guarantor's obligations under this Indenture and the
Securities of such series and the Guarantees endorsed thereon shall be revived
and reinstated as though no deposit had occurred pursuant to this Article Twelve
with respect to Securities of such series until such time as the Trustee or
Paying Agent is permitted to apply all money held in trust pursuant to Section
1205 with respect to Securities of such series in accordance with this Article
Twelve; provided, however, that if the Company makes any payment of principal of
or any premium or interest on any Security of such series following the
reinstatement of its obligations or if the Guarantor makes any payment in
respect thereof pursuant to its Guarantee of such Securities of such series, the
Company or the Guarantor, as the case may be, shall be subrogated to the rights
of the Holders of Securities of such series to receive such payment from the
money so held in trust.

                  The provisions of this Article shall be applicable to any
sinking fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 301 for Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment". If provided for by the terms of Securities of
any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 1302. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

Section 1302. Satisfaction of Sinking Fund Payments with Securities.

                  The Company (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been acquired or redeemed either at the
election of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities or otherwise, in each case in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of such series required
to be made pursuant to the terms of such Securities as provided for by the terms
of such series; provided that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

Section 1303. Redemption of Securities for Sinking Fund.

                  Not less than 45 days prior to each sinking fund payment date
for any series of Securities, the Company will deliver to the Trustee an
Officers' Certificate specifying the amount of the next ensuing sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting Securities
of that series pursuant to Section 1302 and will also deliver to the Trustee any
Securities to be so delivered. Not less than 15 nor more than 45 days before
each such sinking fund payment date the Trustee shall select the Securities to
be redeemed upon such sinking fund payment date in the manner specified in
Section 1103 and cause notice of the redemption thereof to be given in the name
of and at the expense of the Company in the manner provided in Section 1104.
Such notice having been duly given, the redemption of such Securities shall be
made upon the terms and in the manner stated in Sections 1106 and 1107.

                                ARTICLE FOURTEEN

                             Guarantee of Securities

SECTION 1401. Guarantee.

                                      -94-
   103
                  The Guarantor hereby unconditionally guarantees to each Holder
of a Security of each series of the Company authenticated and delivered by the
Trustee or an Authenticating Agent the due and punctual payment of the principal
of (premium, if any) and interest on such Security and the due and punctual
payment of any sinking fund payments provided for pursuant to the terms of such
Security, when and as the same shall become due and payable, whether at Stated
Maturity, by declaration of acceleration, call for redemption or otherwise
according to the terms of such Security and of this Indenture (the "Guaranteed
Obligations"). In case of default by the Company in the payment of any such
principal, premium, interest or sinking fund payment, the Guarantor agrees duly
and punctually to make any such payment when and as the same shall become due
and payable, whether at the Stated Maturity, by declaration of acceleration,
call for redemption or otherwise, and as if such payment were made by the
Company. The Guarantor hereby agrees that its obligations hereunder shall be as
if it were principal debtor and not merely surety, and shall be absolute and
unconditional irrespective of, and shall be unaffected by, the validity,
legality or enforceability of any Security of any series or this Indenture, the
absence of any action to enforce the same or any waiver, modification or
indulgence or consent granted to the Company with respect thereto by the Holder
of any Security of any series or the Trustee, the recovery of any judgment
against the Company or any action to enforce the same, or any other
circumstances which may otherwise constitute a legal or equitable discharge of a
surety or guarantor; provided, however, that notwithstanding the foregoing, no
such waiver, modification or indulgence shall, without the consent of the
Guarantor, increase the principal amount of a Security or the interest rate
thereon or increase any premium payable upon redemption thereof. The Guarantor
hereby waives diligence, presentment, demand of payment, filing of claims with a
court in the event of merger or bankruptcy of the Company, any right of set-off
or counterclaim, any right to require a proceeding first against the Company,
protect or notice with respect to any Security or the indebtedness evidenced
thereby or with respect to any sinking fund payment required pursuant to the
terms of a Security issued under this Indenture and all demands whatsoever, and
covenants that this Guarantee will not be discharged as to any Security except
by payment in full of the principal of (premium, if any) and interest on such
Security.

SECTION 1402. Subrogation.

                  The Guarantor shall be subrogated to all rights of the Holder
of a Security against the Company in respect of

                                      -95-
   104
any amounts paid to such Holder by the Guarantor pursuant to the provisions of
this Guarantee; provided, however, that the Guarantor shall not, without the
consent of all Holders of Securities of such series, be entitled to enforce, or
to receive, any payments arising out of or based upon, such right of subrogation
until the principal of (and premium, if any) and interest then due and payable
on all Securities of the relevant series shall have been irrevocably paid in
full in accordance with the terms of such Securities.

SECTION 1403. Reinstatement.

                  The Guarantee of the Guarantor is a guarantee of payment when
due and not of collection. The Guarantee shall continue to be effective, or be
reinstated, as the case may be, in respect of any Security if at any time
payment, or any part thereof, of such Security is rescinded or must otherwise be
restored or returned by the Holder of such Security or any trustee for said
Holder upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Company or any other entity, or upon or as a result of the
appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for, the Company or any other entity or any substantial part of their
respective property, or otherwise, all as though such payments had not been
made.

SECTION 1404. Execution and Delivery of Guarantees.

                  To evidence its guarantee set forth in Section 1401, the
Guarantor hereby agrees to execute, subject to Section 201, the Guarantee in a
form established pursuant to Section 206, to be endorsed on each Security
authenticated and delivered by the Trustee. Each such Guarantee shall be
executed by the Guarantor as provided in Section 303.

                  The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the Guarantee
endorsed thereon on behalf of the Guarantor.

                                     * * * *

                  This instrument may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.
