         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided 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 agents 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. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred 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 and
the Company, 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 the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his 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 ownership of Registered Securities shall be proved by the
Security Register.

         (d) 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 or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

         (e) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to a Board Resolution, fix in advance a record
date for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of record at the
close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of such record
date; provided that no such authorization, agreement or consent by the Holders
on such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than six months after the
record date.

         SECTION 105.        NOTICES, ETC., TO TRUSTEE AND COMPANY.

         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,

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

         (b) the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to it
at the address of its principal office specified in the first paragraph of this
Indenture, attention: Secretary, or at any other address previously furnished in
writing to the Trustee by the Company.

         SECTION 106.        NOTICE TO HOLDERS; WAIVER.

         Where this Indenture or any Security provides for notice to Holders of
any event, such notice shall be deemed sufficiently given (unless otherwise
herein or in such Security expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at his
address as it appears in the Security Register, not later than the latest date,
and not earlier than the earliest date, prescribed for the giving of such
notice. 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 or the validity of the proceedings to which such notice relates.
Where this Indenture or any Security 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.

         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

         SECTION 107.        CONFLICT WITH TRUST INDENTURE ACT.

         If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required 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 to this Indenture as so modified or shall be

succeeding Business Day or on such other day as may be set out in the Officer's

         PHILADELPHIA CONSOLIDATED HOLDING CORP., a corporation duly organized

the most recent Interest Payment Date to which interest has been paid or duly
provided for, (semi-annually) (quarterly) (monthly) on         and in each year,
commencing           , at the rate of    % per annum, until the principal hereof
is paid or made available for payment (If applicable insert--, and (to the
extent that the payment of such interest shall be legally enforceable) at the
rate of      % per annum on any overdue principal and premium and on any overdue
installment of interest). The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, which shall be the     of     (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.)

         (If the Security is not to bear interest prior to Maturity, insert--The
principal of this Security shall not bear interest except in the case of a
default in payment of principal upon acceleration, upon redemption or at Stated
Maturity and in such case the overdue principal of this Security shall bear
interest at the rate of      % per annum (to the extent that the payment of such
interest shall be legally enforceable), which shall accrue from the date of such
default in payment to the date payment of such principal has been made or duly
provided for. Interest on any overdue principal shall be payable on demand. Any
such interest on any overdue principal that is not so paid on demand shall bear
interest at the rate of     % per annum (to the extent that the payment of such
interest shall be legally enforceable), which shall accrue from the date of such
demand for payment to the date payment of such interest has been made or duly
provided for, and such interest shall also be payable on demand.)

         Payment of the principal of (and premium, if any) and (if applicable,
insert--any such) interest on this Security will be made at the office or agency
of the Company maintained for that purpose in           , in Dollars (if
applicable, insert--; provided, however, that at the option of the Company
payment of interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register).

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

more Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the Indenture.)

         (Notwithstanding the foregoing, the Company may not, prior to

financial practice) of less than     % per annum.)

         (The sinking fund for this series provides for the redemption on

which they become due.)

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

         (If the Security is not an Original Issue Discount Security, insert --
If any Event of Default with respect to Securities of this series shall occur

amount.) Upon payment (i) of the amount of principal so declared due and payable
and (ii) of interest on any overdue principal and overdue interest (in each case
to the extent that the payment of such interest shall be legally enforceable),
all of the Company's obligations in respect of the payment of the principal of
and interest, if any, on the Securities of this series shall terminate.

         This Security is a senior unsecured obligation of the Company and will
rank pari passu in right of payment with all other senior unsecured obligations
of the Company.

         This Security is subject to Defeasance as described in the Indenture.

         The Indenture may be modified by the Company and the Trustee without
consent of any Holder with respect to certain matters as described in the
Indenture. In addition, the Indenture permits, with certain exceptions as
therein provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of
the Securities at the time Outstanding of

each series to be affected. The Indenture also contains provisions permitting
the Holders of a majority 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 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 bind such Holder
and 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 or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, place and rate, 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 registrable 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
premium, if any) 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, of authorized denominations and for the same Stated Maturity and
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 ($1,000) 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 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 Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         The Indenture imposes certain limitations on the ability of the Company
to, among other things, merge or consolidate with any other Person or sell,
assign, transfer or lease all or substantially all of its properties or assets
(If other covenants are applicable pursuant to the provisions of Section 301,
insert here). All such covenants and limitations are subject to a number of
important qualifications and exceptions. The Company must report periodically to
the Trustee on compliance with the covenants in the Indenture.

         A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under this
Security or the Indenture or for any claim based on, in respect of or by reason
of, such obligations or their creation. Each Holder, by accepting a Security,
waives and releases all such liability. The waiver and release are part of the
consideration for the issuance of this Security.

         (If applicable, insert -- Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures ("CUSIP"), the
Company has caused CUSIP numbers to be printed on the Securities of this series
as a convenience to the Holders of the Securities of this series. No
representation is made as to the correctness or accuracy of such numbers as
printed on the Securities of this series and reliance may be placed only on the
other identification numbers printed hereon.)

         All capitalized terms used in this Security without definition which
are defined in the Indenture shall have the meanings assigned to them in the
Indenture.

         SECTION 205.         SECURITIES IN GLOBAL FORM.

         If Securities of a series are issuable in global form, as contemplated
by Section 301, then, notwithstanding the provisions of Section 302, any such
Security shall represent such of the Outstanding Securities of such series as
shall be specified therein and may provide that it shall represent the aggregate
amount of Outstanding Securities from

time to time endorsed thereon and that the aggregate amount of Outstanding
Securities represented thereby may from time to time be reduced to reflect
exchanges. Any endorsement of a Security in global form to reflect the amount,
or any increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made in such manner and upon instructions given by such Person
or Persons as shall be specified therein or in the Company Order to be delivered
to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions
of Section 303 and, if applicable, Section 304, the Trustee shall deliver and

been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Security in global form
shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

         The provisions of Section 309 shall apply to any Security represented
by a Security in global form if such Security was never issued and sold by the
Company and the Company delivers to the Trustee the Security in global form
together with written instructions (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby.

         Notwithstanding the provisions of Sections 201 and 307, unless
otherwise specified as contemplated by Section 301, payment of principal of,
premium, if any, and interest on any Security in permanent global form shall be
made to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat a Person as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security as shall be
specified in a written statement of the Holder of such permanent global
Security.

         SECTION 206.         CUSIP NUMBER.

         The Company in issuing Securities of any series may use a "CUSIP"
number, and, if so, the Trustee may use the CUSIP number in notices of
redemption or exchange as a convenience to Holders of such series; provided,
that any such notice may state that no representation is made as to the
correctness or accuracy of the CUSIP number printed on the notice or on the
Securities of such series, and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the CUSIP number of any series of
Securities.

         SECTION 207.         FORM OF LEGEND FOR THE SECURITIES IN GLOBAL FORM.

         Any Security in global form authenticated and delivered hereunder shall
bear a legend in substantially the following form:

         "This Security is in global form within the meaning of the Indenture
hereinafter referred to and is registered in the name of a Common Depositary or
a U.S. Depositary. Unless and until it is exchanged in whole or in part for
Securities in certificated form, this Security may not be transferred except as
a whole by the Common Depositary or a U.S. Depositary or by a nominee of the
Common Depositary or a nominee of the U.S. Depositary as the case may be."

                                    ARTICLE 3

         (13) if either or both of Section 1302 and Section 1303 shall be

                                       16

   24



         (14) if other than U.S. dollars, the currency or currencies or units

except as to denomination and except as may otherwise be provided in or pursuant
to such Board Resolution and set forth in such Officer's Certificate or in any
such Indenture supplemental hereto.

         If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officer's
Certificate setting forth, or providing the manner for determining, the terms of
the Securities of such series.

         SECTION 302.         DENOMINATIONS.

         The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301. In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

         SECTION 303.         EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile. The seal of the Company
may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Securities. Typographical and other
minor errors or defects in any such reproduction of the seal or any such
signature shall not affect the validity or enforceability of any security that
has been duly authenticated and delivered by the Trustee.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
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.

         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 to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and make such Securities available for
delivery. If the form or terms of the Securities of the series 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,
the Trustee shall be entitled to receive, and (subject to Sections 315(a)
through (d) of the Trust Indenture Act) shall be fully protected in relying
upon, an Opinion of Counsel stating,

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


                                                          
                                       17

   25



         (b) if the terms of such Securities have been established by or
pursuant to Board Resolution as permitted by Section 301, that such terms have
been established in 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, except
to the extent enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws affecting the
enforcement of creditors' rights generally and by the effect of general
principles of equity (regardless of whether enforceability is considered in a
proceeding in equity or at law); and

         (d) that no consent, approval, authorization, order, registration or
qualification of or with any court or any governmental agency or body having
jurisdiction over the Company is required for the execution and delivery of such
Securities by the Company, except such as have been obtained (except that no
opinion need be expressed as to state securities or Blue Sky laws).

         If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee, or in the written opinion of
counsel to the Trustee (which counsel may be an employee of the Trustee) such
authentication may not lawfully be made or would involve the Trustee in personal
liability.

         Notwithstanding the provisions of Section 301 and of the immediately
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 Officer's
Certificate otherwise required pursuant to Section 301 or the Company Order and
Opinion of Counsel otherwise required pursuant to the immediately preceding
paragraph at or prior to the time of authentication of each security of such
series if such documents are delivered at or prior to the authentication upon
original issuance of the first security of such series to be issued.

         If the Company shall establish pursuant to Section 301 that the
Securities of a series are to be issued in the form of one or more global
Securities, then the Company shall execute and the Trustee shall, in accordance
with this Section and the Company Order with respect to the authentication and
delivery of such series, authenticate and deliver one or more global Securities
that (i) shall be in an aggregate amount equal to the aggregate principal amount
specified in such Company Order, (ii) shall be registered in the name of the
Common Depositary or U.S. Depositary, as the case may be, therefor or its
nominee, and (iii) shall be made available for delivery by the Trustee to such
depositary or pursuant to such depositary's instruction.

         Each depositary designated pursuant to Section 301 must, at the time of
its designation and at all times while it serves as depositary, be a clearing
agency registered under the Exchange Act and any other applicable statute or
regulation.

         Unless otherwise provided for in the form of security, each security
shall be dated the date of its authentication.

         No security 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 is 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
make available for delivery, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,

                                                          
                                       18

   26



substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

         In the case of Securities of any series, such temporary Securities may
be in global form, representing all or a portion of the Outstanding Securities
of such series.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with the provisions of Section 305), 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 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 make
available for delivery in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor. 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.

         If temporary Securities of any series are issued in global form, any
such temporary global Security shall, unless otherwise provided therein, be
delivered to the office of a depositary or common depositary (the "COMMON
DEPOSITARY") for credit to the respective accounts of the beneficial owners of
such Securities (or to such other accounts as they may direct).

         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 may prescribe, the Company shall provide for the
registration of Securities and of registration 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 of the Company in Place of Payment for that
series, the Company shall execute, and the Trustee shall authenticate and make
available for delivery, 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 Stated Maturity.

         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 Stated Maturity, 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 make available for delivery, the Securities which the Holder
making the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global security shall be exchangeable
only as provided in this paragraph. If the beneficial owners of interests in a
permanent global security are entitled to exchange such interests for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified and as subject to the conditions contemplated by
Section 301, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in aggregate
principal amount equal to the principal amount of such permanent global
security, executed by the Company. On or after the earliest date on which such
interests may be so exchanged, such permanent global Securities shall be
surrendered from time to time by the Common Depositary or the U.S. Depositary,
as the case may be, and in accordance with instructions given to the Trustee and
the Common Depositary or the U.S. Depositary, as the case may be (which
instructions shall be in writing but need not comply with Section 102 or be
accompanied by an Opinion of Counsel), as shall be specified in the Company
Order with respect thereto to the Trustee, as the Company's agent for such
purpose, to be exchanged, in whole or in part, for definitive Securities of the
same series

                                                          
                                       19

   27



without charge. The Trustee shall authenticate and make available for delivery,
in exchange for each portion of such surrendered permanent global security, a
like aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such permanent
global security to be exchanged which shall be in the form of the Securities of
such series; provided, however, that no such exchanges may occur 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.
Promptly following any such exchange in part, such permanent global Security
shall be returned by the Trustee to the Common Depositary or the U.S.
Depositary, as the case may be, or such other Common Depositary or U.S.
Depositary referred to above in accordance with the written instructions of the
Company referred to above. If a Security in the form specified for such series
is issued in exchange for any portion of a permanent global Security after the
close of business at the office or agency where such exchange occurs on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of interest or Defaulted Interest, as the case may be, such
interest or Defaulted Interest will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such security in
the form specified for such series, but will be payable on such Interest Payment
Date or proposed date for payment, as the case may be, only to the Person to
whom interest in respect of such portion of such permanent global Security is
payable in accordance with the provisions of this Indenture.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligation, of the Company, 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 or
for exchange 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.

         Unless otherwise provided in the Securities to be transferred or
exchanged, no service charge shall be made for any registration of transfer or
exchange of Securities, but the Company 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.

         The Company shall not 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.

         SECTION 306.         MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such Security or indemnity as may be required by 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 upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount 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, make payment with respect to such Security.

                                                          
                                       20

   28



         Upon the issuance of any new Security under this Section, the Company
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
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, 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.

         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
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 Section
307 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 10
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 Section
307, such manner of payment shall be deemed practicable by the Trustee.

         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.


                                                          
                                       21

   29



         SECTION 308.         PERSONS DEEMED OWNERS.

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

         None of the Company, the Trustee or any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interest of a
Security in global form, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest. Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall
prevent the Company or the Trustee or any agent of the Company or the Trustee
from giving effect to any written certification, proxy or other authorization
furnished by any Common Depositary (or its nominee), as a Holder, with respect
to such Security in global form or impair, as between such Common Depositary and
owners of beneficial interests in such Security in global form, the operation of
customary practices governing the exercise of the right of such Common
Depositary (or its nominee) as holder of such Security in global form.

         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 may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, 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 cancelled as provided in this Section, except as expressly permitted
by this Indenture. All cancelled Securities shall be held by the Trustee and may
be destroyed (and, if so destroyed, certification of their destruction shall be
delivered to the Company, unless, by a Company Order, the Company shall direct
that cancelled Securities be returned to it).

         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 consisting of twelve 30-day months.

                           SATISFACTION AND DISCHARGE

         SECTION 401.         SATISFACTION AND DISCHARGE OF INDENTURE.

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

         (1)    either

                (A) all Securities 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 for
whose payment money has theretofore been deposited in trust or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged
from such trust, as provided in Section 1009) have been delivered to the Trustee
for cancellation; or


                                                          
                                       22

   30



                  (B) all such Securities 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, in the case of (i), (ii) or (iii) above, has deposited with the
Trustee as trust funds in trust for the purpose an amount sufficient to pay and
discharge the entire indebtedness on such Securities not theretofore delivered
to the Trustee for cancellation, for principal (and premium, if any) and
interest to the date of such deposit (in the case of Securities which have
become due and payable) or the Stated Maturity or Redemption Date, as the case
may be;

         (2) the Company 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 Officer's Certificate
and an Opinion of Counsel, each stating that all conditions precedent provided
for herein relating to the satisfaction and discharge of this Indenture have
been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Company 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 1009 shall survive.

         SECTION 402.               APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1009, all
money 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 acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with or
received by the Trustee.

                                    ARTICLE 5

                                    REMEDIES

         SECTION 501.               EVENTS OF DEFAULT.

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

         (1) the Company defaults in the payment of interest on any Security of
that series when such interest becomes due and payable and the default continues
for a period of 30 days; provided, however, that if the Company is permitted by
the terms of the Securities of the applicable series to defer the payment in
question, the date on which such payment is due and payable shall be the date on
which the Company is required to make payment following such deferral, if such
deferral has been elected pursuant to the terms of the Securities; or

         (2) the Company defaults in the payment of the principal of (or
premium, if any, on) any Security of that series when the same becomes due and
payable at Maturity, upon redemption (including redemptions under Article 11),
or otherwise; provided, however, that if the Company is permitted by the terms
of the Securities of the applicable series to defer the payment in question, the
date on which such payment is due and payable shall be the date

                                                          
                                       23

   31



on which the Company is required to make payment following such deferral, if
such deferral has been elected pursuant to the terms of the Securities; or

         (3) the Company fails to observe or perform any of its other covenants,
warranties or agreements in the Securities of that series or this Indenture
(other than a covenant, agreement or warranty a default in whose performance or
whose breach is elsewhere in this Section specifically dealt with or which has
expressly been included in this Indenture solely for the benefit of series of
Securities other than that series), and the failure to observe or perform
continues for the period and after the notice specified in the last paragraph of
this Section; or

         (4) any Event of Default under any series of Securities issued pursuant
to this Indenture or any event of default, as defined in any other Indenture,
mortgage, indenture, or instrument under which there may be issued, or by which
there may be secured or evidenced, any Indebtedness of the Company or a
Subsidiary (whether such Indebtedness now exists or shall hereafter be created
or incurred) shall occur and shall consist of default in the payment of such
Indebtedness at the maturity thereof (after giving effect to any applicable
grace period) or shall result in Indebtedness becoming or being declared due and
payable prior to the date on which it would otherwise become due and payable,
and such default in payment is not cured or such acceleration shall not be
rescinded or annulled within 10 days after written notice to the Company from
the Trustee or to the Company and to the Trustee from the Holders of at least
10% in aggregate principal amount of the Securities of that series at the time
outstanding; provided that it shall not be an Event of Default if the principal
amount of Indebtedness (other than Indebtedness represented by Securities issued
pursuant to this Indenture) which is not paid at maturity or the maturity of
which is accelerated is less than the amount equal to 1% of the Company's
consolidated total assets (determined as of its most recent fiscal year-end)
provided further that if, prior to a declaration of acceleration of the maturity
of the Securities of that series or the entry of judgment in favor of the
Trustee in a suit pursuant to Section 503, such default shall be remedied or
cured by the Company or waived by the 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 of the Securities of that series, and
provided further, that, subject to Sections 601 and 602, the Trustee shall not
be charged with knowledge of any such default unless written notice of such
default shall have been given to the Trustee by the Company, by a holder or an
agent of a holder of any such Indebtedness, by the trustee then acting under any
indenture or other instrument under which such default shall have occurred, or
by the Holders of at least five percent in aggregate principal amount of the
Securities of that series at the time outstanding; or

         (5) the Company pursuant to or within the meaning of any Bankruptcy Law
(A) commences a voluntary case or proceeding under any Bankruptcy Law with
respect to itself, (B) consents to the entry of a judgment, decree or order for
relief against it in an involuntary case or proceeding under any Bankruptcy Law,
(C) consents to or acquiesces in the institution of bankruptcy or insolvency
proceedings against it, (D) applies for, consents to or acquiesces in the
appointment of or taking possession by a Custodian of the Company or for any
material part of its property, (E) makes a general assignment for the benefit of
its creditors or (F) takes any corporate action in furtherance of or to
facilitate, conditionally or otherwise, any of the foregoing; or

         (6) (i) a court of competent jurisdiction enters a judgment, decree or
order for relief in respect of the Company in an involuntary case or proceeding
under any Bankruptcy Law which shall (A) approve as properly filed a petition
seeking reorganization, arrangement, adjustment or composition in respect of the
Company, (B) appoint a Custodian of the Company or for any material part of its
property, or (C) order the winding-up or liquidation of its affairs, and such
judgment, decree or order shall remain unstayed and in effect for a period of 60
consecutive days; or (ii) any bankruptcy or insolvency petition or application
is filed, or any bankruptcy or insolvency proceeding is commenced against the
Company and such petition, application or proceeding is not dismissed within 60
days; or (iii) a warrant of attachment is issued against any material portion of
the property of the Company which is not released within 60 days of service; or

         (7) any other Event of Default provided with respect to Securities of
that series.

         A Default under clause (3) above is not an Event of Default until the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities of that series notify the Company of the Default and the
Company does not cure the Default within 60 days after receipt of the notice.
The notice must specify the Default,

                                                          
                                       24

   32



demand that it be remedied and state that the notice is a "Notice of Default."
When a Default under clause (3) above is cured within such 60-day period, it
ceases.

         SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series (other
than an Event of Default specified in clause (5) or (6) of Section 501) occurs
and is continuing, the Trustee by notice in writing to the Company, or the
Holders of at least 25% in aggregate principal amount of the Outstanding
Securities of that series by notice in writing to the Company and the Trustee,
may declare the unpaid principal of and accrued interest to the date of
acceleration (or, if the Securities of that series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of that series) on all the Outstanding Securities of that series to be due
and payable immediately and, upon any such declaration, the Outstanding
Securities of that series (or specified principal amount) shall become and be
immediately due and payable.

         If an Event of Default specified in clause (5) or (6) of Section 501
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or specified principal amount) shall ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder of any Security of that series.

         Upon payment of all such principal and interest, all of the Company's
obligations under the Securities of that series and (upon payment of the
Securities of all series) this Indenture shall terminate, except obligations
under Section 607.

         The Holders of a majority in principal amount of the Outstanding
Securities of that series by notice to the Trustee may rescind an acceleration
and its consequences if (i) all existing Events of Default, other than the
nonpayment of the principal and interest of the Securities of that series that
has become due solely by such declaration of acceleration, have been cured or
waived, (ii) to the extent the payment of such interest is lawful, interest on
overdue installments of interest and overdue principal that has become due
otherwise than by such declaration of acceleration have been paid, (iii) the
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction and (iv) all payments due to the Trustee and any
predecessor Trustee under Section 607 have been made.

         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 of
any series when such 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 of any series at the Maturity thereof,

the Company will, upon 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 premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) 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 reasonable costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

         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 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 or any other obligor upon such Securities, wherever
situated.


                                                          
                                       25

   33



         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 secure any other proper remedy.

         SECTION 504.               TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

         (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 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 agent and
counsel) and of the Holders allowed in such judicial proceedings, 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.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

         SECTION 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, 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 in respect
of the Securities of any series 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 premium, if any) or interest, upon
presentation of the Securities in respect of which moneys have been collected
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
applicable to such series;

         Second: To the payment of the amounts then due and unpaid for principal
of (and premium, if any) and interest on the Securities of such series in
respect of which or for the benefit of which such money has been collected,

                                                          
                                       26

   34



ratably, without preference or priority of any kind, according to the amounts
due and payable on such Securities of such series for principal (and premium, if
any) and interest, respectively; and

         Third: To the Company.

         The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 506. At least fifteen (15) days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

         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 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 reasonable
indemnity 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 Holders of Securities of
any series 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 Holders of Securities of the affected series.

         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 premium, if any) and (subject to
Section 307) 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 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 has been instituted.


                                                          
                                       27

   35



         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. 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.

         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;

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

         (3) subject to Section 601, the Trustee need not take any action which
might involve the Trustee in personal liability or be unduly prejudicial to the
Holders not joining therein.

         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 by written notice to the Trustee on
behalf of the Holders of all the Securities of such series waive any Default or
Event of Default with respect to such series and its consequences, except a
Default or Event of Default

         (1) in respect of the payment of the principal of (or premium, if any)
or interest on any Security of such series, or

         (2) in respect of a covenant or other 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.

         Upon any such waiver, such Default or Event of Default shall cease to
exist and shall be deemed to have been cured, for every purpose of this
Indenture and the Securities of such series; but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereon.

         SECTION 514.               UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, 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, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of

                                                          
                                       28

   36



this Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder

                                   THE TRUSTEE

         SECTION 601.               CERTAIN DUTIES AND RESPONSIBILITIES OF 
                                    THE TRUSTEE.

         (a) Except during the continuance of an Event of Default, the Trustee's
duties and responsibilities under this Indenture shall be governed by Section
315(a) of the Trust Indenture Act.

         (b) In case an Event of Default has occurred and is continuing, and is
known to the Trustee, the Trustee shall exercise the rights and powers vested in
it by this Indenture, and shall use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

         (c) None of the provisions of Section 315(d) of the Trust Indenture Act
shall be excluded from this Indenture.

         SECTION 602.               NOTICE OF DEFAULTS.

         Within 30 days after the occurrence of any Default or Event of Default
with respect to the Securities of any series, the Trustee shall give to all
Holders of Securities of such series, as their names and addresses appear in the
Security Register, notice of such Default or Event of Default known to the
Trustee, unless such Default or Event of Default shall have been cured or
waived; provided, however, that, except in the case of a Default or Event of
Default in the payment of the principal of (or premium, if any) or interest on
any Security of such series or in the payment of any sinking fund installment
with respect to Securities of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or directors or Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the Holders
of Securities of such series.

         SECTION 603.               CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of the Trust Indenture Act:

         (a) the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

         (b) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

         (c) whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established 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 Officer's Certificate;

         (d) the Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in reliance thereon;


                                                          
                                       29

   37



         (e) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders pursuant to this Indenture, unless such Holders shall have
offered to the Trustee security or indemnity to its reasonable satisfaction
against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

         (f) prior to the occurrence of an Event of Default with respect to the
Securities of any series and after the curing or waiving of all such Events of
Default which may have occurred, the Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, approval or other paper or document, or the books and records of the
Company, unless requested in writing to do so by the Holders of a majority in
principal amount of the Outstanding Securities of any series; provided, however,
that if the payment within a reasonable time to the Trustee of the costs,
expenses or liabilities likely to be incurred by it in the making of such
investigation is not, in the opinion of the Trustee, reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding; the reasonable expense of every
such investigation shall be paid by the Company or, if paid by the Trustee,
shall be repaid by the Company upon demand;

         (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; and

         (h) the Trustee shall not be required 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 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.

         SECTION 604.               NOT RESPONSIBLE FOR RECITALS OR ISSUANCE 
                                    OF SECURITIES.

         The recitals herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
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. Neither the Trustee nor any
Authenticating Agent shall 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, 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 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 (including amounts held by
the Trustee as Paying Agent) 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 otherwise agreed upon in writing
with the Company.

         SECTION 607.               COMPENSATION AND REIMBURSEMENT.

         The Company agrees

         (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);


                                                          
                                       30

   38



         (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its 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 the expenses and
disbursements of its agents and 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, damage, claim or expense, including taxes (other than taxes
based upon or determined or measured by the income of the Trustee), incurred
without gross 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 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.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

         The provisions of this Section 607 shall survive this Indenture.

         SECTION 608.               DISQUALIFICATION; CONFLICTING INTERESTS.

         The Trustee shall be disqualified only where such disqualification is
required by Section 310(b) of the Trust Indenture Act. Nothing shall prevent the
Trustee from filing with the Commission the application referred to in the
second to last paragraph of Section 310(b) of the Trust Indenture Act.

         SECTION 609.               CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee hereunder which shall be eligible
to act as Trustee under Section 310(a)(1) of the Trust Indenture Act having a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by federal or state authority. If such corporation 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 corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. Neither the Company nor any Person directly or indirectly
controlling, controlled by, or under common control with the Company may serve
as Trustee. 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. 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.


                                                          
                                       31

   39



         (d)    If at any time:

                (1) the Trustee shall fail to comply with Section 310(b) of the
Trust Indenture Act after written request therefor by the Company 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 herefor by the Company or by any such
Holder of a Security who has been a bona fide Holder of a Security for at least
six months; 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 315(e) of the
Trust Indenture Act, any Holder who has been a bona fide Holder of a security
for at least six months may, on behalf of himself 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 retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements 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 with
respect to such Securities. 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 himself 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 by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
security Register. 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 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 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.


                                                          
                                       32

   40



         (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
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee 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, (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 Trustees 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 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 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 paragraph (a) or (b) of this Section, as the case may be.

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

         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.

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

         SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT.

         At any time when any of the Securities remain Outstanding the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of, and subject to the
direction of, the Trustee to authenticate Securities of such series issued 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

                                                          
                                       33

   41



Authenticating Agent. Each Authenticating Agent shall be acceptable to the
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 may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. 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 if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

         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 alternate
certificate of authentication in the following form:

                         Form of Authenticating Agent's
                          Certificate of Authentication


Dated:

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

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

         SECTION 701. COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

         The Company will furnish or cause to be furnished to the Trustee:

         (a) semi-annually, not later than January 1 and July 1 in each year, a
list, in such form as the Trustee may reasonably require, of the names and
addresses of the Holders as of the preceding December 15 or June 15, as the case
may be; and

         (b) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished;

provided, however, that so long as the Trustee is the Security Registrar, no
such list shall be required to be furnished.

         SECTION 702. PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

         (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

         (b) If three or more Holders (herein referred to as "applicants") apply
in writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants desire to communicate with other Holders with respect to their rights
under this Indenture or under the Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit
then the Trustee shall, within five Business Days after the receipt of such
application, at its election, either

                  (i) afford such applicants access to the information preserved
at the time by the Trustee in accordance with Section 702(a); or

                  (ii) inform such applicants as to the approximate number of
Holders whose names and addresses appear in the information preserved at the
time by the Trustee in accordance with Section 702(a), and as to the approximate
cost of mailing to such Holders the form of proxy or other communication, if
any, specified in such application.

         If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appears in the information preserved
at the time by the Trustee in accordance with Section 702(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all objections so sustained have
been met and shall enter an order so declaring, the Trustee shall mail copies of
such material to all such Holders with reasonable promptness after the entry of
such order and the renewal of such tender; otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.

         (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 702(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 702(b).

         SECTION 703.               REPORTS BY TRUSTEE.

Indenture Act.

         (b) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Trustee with each stock exchange upon which any

the foregoing as the Commission may from time to time by rules and regulations
prescribe) which the Company may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company
is not required to file information, documents or reports pursuant to either of
said Sections, then it shall file with the Trustee and the Commission, in
accordance with rules and regulations prescribed from time to time by the
Commission, such of the supplementary and periodic information, documents and
reports which may be required pursuant to Section 13 of the Exchange Act in
respect of a security listed and registered on a national securities exchange as
may be prescribed from time to time in such rules and regulations;

         (2) file with the Trustee and the Commission, in accordance with rules
and regulations prescribed from time to time by the Commission, such additional
information, documents and reports with respect to compliance by the Company

prescribed from time to time by the Commission; and

         (4) furnish to the Trustee, on or before May 1 of each year, a brief

period of grace or requirement of notice provided under this Indenture. Such
certificate need not comply with Section 102.

        SECTION 901. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.

Without notice to or the consent of any Holders, the Company, when authorized by

enter into one or more indentures supplemental hereto, in form satisfactory to
the Trustee, for any of the following purposes:

         (1) to evidence the succession of another corporation to the Company
and the assumption by any such successor of the covenants of the Company herein
and in the Securities; or


                                                          
                                       37

   45



         (2) to add to the covenants of the Company for the benefit of the
Holders of all or any series of Securities (and if such covenants are to be for
the benefit of less than all series of Securities, stating that such covenants
are expressly being included solely for the benefit of series) or to surrender
any right or power herein conferred upon the Company; or

         (3) to add any additional Events of Default with respect to all or any
series of Securities; or

         (4) to add or change any of the provisions of this Indenture to such
extent as shall be necessary to permit or facilitate the issuance of Securities
in bearer form, registrable or not registrable as to principal, and with or
without interest coupons; or

         (5) to change or eliminate any of the provisions of this Indenture,
provided that any such change or elimination shall become effective only when
there is no Security Outstanding of any series created prior to the execution of
such supplemental Indenture which is entitled to the benefit of such provision;
or

         (6)      to secure the Securities; or

         (7) to establish the form or terms of Securities of any series as
permitted by Sections 201 and 301; or

         (8) to evidence and provide for the acceptance of appointment hereunder
by a successor Trustee with respect to the Securities of one or more series and

611(b); or

         (9) to cure any ambiguity, defect or inconsistency or to correct or
supplement any provision herein which may be inconsistent with any other
provision herein; or

         (10) to make any change that does not materially adversely affect the
interests of the Holders of Securities of any series.

         Upon request of the Company, accompanied by a Board Resolution
authorizing the execution of any such supplemental indenture, and upon receipt
by the Trustee of the documents described in (and subject to the last sentence
of) Section 903, the Trustee shall join with the Company in the execution of any
supplemental indenture authorized or permitted by the terms of this Indenture.

         SECTION 902. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the written consent of the Holders of a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee
shall, subject to Section 903, enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of
modifying in any manner the rights of the Holders of Securities of such series
under this Indenture; provided, however, that no such supplemental indenture
shall, without the consent of the Holder of each Outstanding security affected
thereby,

         (1) change the Stated Maturity of the principal of, or any installment
of principal of or interest on, any security, or reduce the principal amount
thereof or the rate of interest thereon or any premium payable upon the
redemption thereof or extend the time for payment thereof, or reduce the amount
of the principal of an Original Issue Discount security that would be due and
payable upon a declaration of acceleration of the Maturity thereof pursuant to
Section 502, or change any Place of Payment where, or the coin or currency in
which, any security or any premium or the interest thereon is payable, or impair
the right to institute suit for the enforcement of any such payment on or after
the Stated Maturity thereof (or, in the case of redemption, on or after the
Redemption Date);

         (2) reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for

                                                          
                                       38

   46



any waiver of compliance with certain provisions of this Indenture or Defaults
or Events of Default hereunder and their consequences provided for in this
Indenture; or

         (3) change the redemption provisions (including Article Eleven) hereof
in a manner adverse to such Holder; or

         (4) modify any of the provisions of this Section or Section 513, except
to increase any such percentage or to provide that certain other provisions of
this Indenture cannot be modified or waived without the consent of the Holder of
each Outstanding Security affected thereby; provided, however, that this clause
shall not be deemed to require the consent of any Holder with respect to changes
in the references to "the Trustee" and concomitant changes in this Section, or
the deletion of this proviso, in accordance with the requirements of Sections
611(b) and 901(8).

         A supplemental indenture which changes or eliminates any covenant or
other provisions of this Indenture which as expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

         SECTION 903. EXECUTION OF SUPPLEMENTAL INDENTURES.

         The Trustee shall sign any supplemental indenture authorized pursuant
to this Article, subject to the last sentence of this Section 903. In executing,
or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by
this Indenture, the Trustee shall be entitled to receive, and (subject to
Section 601) shall be fully protected in relying upon, an Officer's Certificate
and an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

         SECTION 904. EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
Indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

         SECTION 905. CONFORMITY WITH TRUST INDENTURE ACT.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 906. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

         Securities of any series authenticated and delivered after the
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
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticate and delivered by the
Trustee in exchange for Outstanding Securities of such series.

                                    COVENANTS

         SECTION 1001. PAYMENTS OF SECURITIES.

         With respect to each series of Securities, the Company will duly and
punctually pay the principal of (and premium, if any) and interest on such
Securities in accordance with their terms and this Indenture, and will duly
comply with all the other terms, agreements and conditions contained in, or made
in the Indenture for the benefit of, the Securities of such series.

         SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

         The Company will maintain an office or agency in each Place of Payment
where Securities may be surrendered for registration of transfer or exchange or
for presentation for payment, where notices and demands to or upon the Company
in respect of the Securities and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and any change in
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 address of the Trustee as set forth in Section 105
hereof and the Company hereby appoints the Trustee as its agent to receive all
presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations. 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.

         SECTION 1003. CORPORATE EXISTENCE.

         Subject to Article 8 hereof, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence and that of each of its Subsidiaries and the rights (charter and
statutory) of the Company and its Subsidiaries; provided, however, that (a) the
Company shall not be required to preserve any such right, license or franchise
or the corporate existence of any of its Subsidiaries if the Board of Directors,
or the board of directors of the Subsidiary concerned, as the case may be, shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company or any of its Subsidiaries and that the loss thereof
is not materially disadvantageous to the Holders, and (b) nothing herein
contained shall prevent any Subsidiary of the Company from liquidating or
dissolving, or merging into, or consolidating with the Company (provided that
the Company shall be the continuing or surviving corporation) or with any one or
more Subsidiaries if the Board of Directors or the board of directors of the
Subsidiary concerned, as the case may be, shall so determine.

         SECTION 1004. PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company will pay or discharge, or cause to be paid or discharged,
before the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a material lien upon the property of the Company or any Subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings and for which adequate provision has been made.

   48



         SECTION 1005. MAINTENANCE OF PROPERTIES.

         The Company will cause all material properties used or useful in the
conduct of its business or the business of any of its Subsidiaries to be
maintained and kept in good condition, repair and working order (normal wear and
tear excepted) and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary, so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from discontinuing the operation or maintenance of any of
such properties, or disposing of any of them, if such discontinuance or disposal
is, in the judgment of the Board of Directors or of the board of directors of
the Subsidiary concerned, as the case may be, desirable in the conduct of the
business of the Company or any Subsidiary of the Company and not materially
disadvantageous to the Holders.

         SECTION 1006. COMPLIANCE CERTIFICATES.

         (a) The Company shall deliver to the Trustee within 90 days after the
end of each fiscal year of the Company (which fiscal year currently ends on
December 31), an Officer's Certificate stating whether or not the signer knows
of any Default or Event of Default by the Company that occurred prior to the end
of the fiscal year and is then continuing. If the signer does know of such a
Default or Event of Default, the certificate shall describe each such Default or
Event of Default and its status and the specific section or sections of this
Indenture in connection with which such Default or Event of Default has
occurred. The Company shall also promptly notify the Trustee in writing should
the Company's fiscal year be changed so that the end thereof is on any date
other than the date on which the Company's fiscal year currently ends. The
certificate need not comply with Section 102 hereof.

         (b) The Company shall deliver to the Trustee, within 10 days after the
occurrence thereof, notice of any acceleration which with the giving of notice
and the lapse of time would be an Event of Default within the meaning of Section
501(4) hereof.

         (c) The Company shall deliver to the Trustee forthwith upon becoming
aware of a Default or Event of Default (but in no event later than 10 days after
the occurrence of each Default or Event of Default that is continuing), an
Officer's Certificate setting forth the details of such Default or Event of
Default and the action that the Company proposes to take with respect thereto
and the specific section or sections of this Indenture in connection with which
such Default or Event of Default has occurred.

         SECTION 1007. COMMISSION REPORTS.

         (a) The Company shall file with the Trustee, within 30 days after it
files them with the Commission, copies of the quarterly and annual reports and
of the information, documents, and other reports (or copies of such portions of
any of the foregoing as the Commission may by rules and regulations prescribe)
which the Company is required to file with the Commission pursuant to Section 13
or 15(d) of the Exchange Act. If the Company is not subject to the requirement
of such Section 13 or 15(d) of the Exchange Act, the Company shall file with the
Trustee, within 30 days after it would have been required to file such
information with the Commission, financial statements, including any notes
thereto and, with respect to annual reports, an auditors' report by an
accounting firm of established national reputation and a "Management's
Discussion and Analysis of Financial Condition and Results of Operations," both
comparable to that which the Company would have been required to include in such
annual reports, information, documents or other reports if the Company had been
subject to the requirements of such Sections 13 or 15(d) of the Exchange Act.
The Company also shall comply with the other provisions of Section 314(a) of the
Trust Indenture Act.

         (b) So long as the Securities remain outstanding, the Company shall
cause its annual report to shareholders and any other financial reports
furnished by it to shareholders generally, to be mailed to the Holders at their
addresses appearing in the register of Securities maintained by the Security
Registrar in each case at the time of such mailing or furnishing to
shareholders. If the Company is not required to furnish annual or quarterly
reports to its shareholders pursuant to the Exchange Act, the Company shall
cause its financial statements, including any notes thereto and, with respect to
annual reports, an auditors' report by an accounting firm of established
national reputation and a "Management's Discussion and Analysis of Financial
Condition and Results of Operations," to be so filed with

                                                          
                                       41

   49



the Trustee and mailed to the Holders within 90 days after the end of each of
the Company's fiscal years and within 45 days after the end of each of the first
three quarters of each fiscal year.

         (c) The Company shall provide the Trustee with a sufficient number of
copies of all reports and other documents and information that the Company may
be required to deliver to the Holders under this Section 1007.

         SECTION 1008. WAIVER OF STAY, EXTENSION OR USURY LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim, and will actively resist any and all efforts to be compelled to take the
benefit or advantage of, any stay or extension law or any usury law or other
law, which would prohibit or forgive the Company from paying all or any portion
of the principal of and/or interest on the Securities as contemplated herein,
wherever enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture; and (to the extent that it may
lawfully do so) the Company hereby expressly waives all benefit or advantage of
any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

         SECTION 1009. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Company 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 (and premium, if any) 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 premium, if any) or 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 (and
premium, if any) or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure to so 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) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Securities of that series in trust for the
benefit of the Persons entitled thereto until such sums shall be paid to such
Persons or otherwise disposed of as herein provided;

         (ii) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities of that series) in the making of any payment
of principal (and premium, if any) or interest on the Securities of that series;
and

         (iii) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

         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, in trust for the payment of the principal of (and premium, if
any) or interest on any security of any series and remaining unclaimed

for two years after such principal (and premium, if any) or interest has become
due and payable shall be paid to the Company on Company Request, or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
security shall thereafter, as an unsecured general creditor, look only to the
Company 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 as
trustee thereof, shall thereupon cease; provided, however, that the Trustee of
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 New York, 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.

         SECTION 1010. LIMITATION ON LIENS.

Company or any of its Subsidiaries, except:

         (i) Liens for taxes, assessments or governmental charges or levies on
its property if the same shall not at the time be delinquent or thereafter can
be paid without penalty or are being contested in good faith and by appropriate
proceedings and for which adequate reserves in accordance with generally
accepted principles of accounting shall have been set aside on its books.

         (ii) Liens imposed by law, such as carriers', warehousemen's and
mechanics' liens and other similar liens arising in the ordinary course of
business which secure payment of obligations not more than 60 days past due or
which are being contested in good faith by appropriate proceedings and for which
adequate reserves shall have been set aside on its books.

         (iii) Liens arising out of pledges or deposits under worker's
compensation laws, unemployment insurance, old age pensions, or other social
security or retirement benefits, or similar legislation.

         (iv) Utility easements, building restrictions and such other
encumbrances or charges against real property as are of a nature generally
existing with respect to properties of a similar character and which do not in
any material way affect the marketability of the same or interfere with the use
thereof in the business of the Company or its Subsidiaries.

         (v) Liens on the capital stock, partnership interest, or other evidence
of ownership of any Subsidiary or such Subsidiary's assets that secure
financings for such Subsidiary.

         (vi) Purchase money liens upon or in property now owned or hereafter
acquired in the ordinary course of business (consistent with the Company's
business practices) to secure (A) the purchase price of such property or (B)
Indebtedness incurred solely for the purpose of financing the acquisition,
construction, or improvement of any such property to be subject to such liens,
or Liens existing on any such property at the time of acquisition, or
extensions, renewals, or replacements of any of the foregoing for the same or a
lesser amount; provided that no such lien shall extend to or cover any property
other than the property being acquired, constructed, or improved and
replacements, modifications, and proceeds of such property, and no such
extension, renewal, or replacement shall extend to or cover any property not
theretofore subject to the Lien being extended, renewed, or replaced.

         (vii) Liens existing on the date Securities are first issued hereunder.

         (viii) Liens for no more than 90 days arising from a transaction
involving accounts receivable or third-party reimbursements of the Company
(including the sale of such accounts receivable or third-party reimbursements),
where such accounts receivable or third-party reimbursements arose in the
ordinary course of the Company's business.

         SECTION 1011. WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any
covenant or condition set forth in Sections 1010 or 1011 hereof, if before or
after the time for such compliance the Holders of not less than a majority in
principal amount of the Securities at the time Outstanding of each series which
is affected thereby, shall, by consent in writing of such Holders, either waive
such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or conditions except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect.

                            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.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution. 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 45
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 and of the principal amount of Securities of such series 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 furnish the Trustee with an
Officer's 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, the
particular Securities to be redeemed shall be selected not more than 90 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, substantially pro rata, by lot
or by any other method as the Trustee considers fair and appropriate and that
complies with the requirements of the principal national securities exchange, if
any, on which such Securities are listed, 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; provided that
in case the Securities of such series have different terms and maturities, the
Securities to be redeemed shall be selected by the Company and the Company shall
give notice thereof to the Trustee.

         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 the 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 45 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at this address appearing in
the Security Register.


                                                          
                                       44

   52



         All notices of redemption shall state:

         (1)      the Redemption Date;

         (2)      the Redemption Price;

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

         (4) that on the Redemption Date the Redemption Price will be come 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;

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

         (7) the CUSIP number, if any, of the Securities to be redeemed; and

         (8) unless otherwise provided as to a particular series of Securities,
if at the time of publication or mailing of any notice of redemption the Company
shall not have deposited with the Trustee or Paying Agent and/or irrevocably
directed the Trustee or Paying Agent to apply, from money held by it available
to be used for the redemption of Securities, an amount in cash sufficient to
redeem all of the Securities called for redemption, including accrued interest
to the Redemption Date, such notice shall state that it is subject to the
receipt of the redemption moneys by the Trustee or Paying Agent before the
Redemption Date (unless such redemption is mandatory) and such notice shall be
of no effect unless such moneys are so received before such date.

         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 1009) 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 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 Predecessor Securities, registered as
such at the close of business on the relevant Regular or Special 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 premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
thereof or in the security.

         SECTION 1107.              SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at an office or agency of the Company 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 Stated Maturity, 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.

                                  SINKING FUNDS

         SECTION 1201. APPLICABILITY OF ARTICLE.

         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 redemption as
provided in Section 1202. 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 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Company (1) may deliver Securities of a series (other than any
Securities previously called for redemption) and (2) may apply as a credit
Securities of a series which have been 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, 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 1203. 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 Officer's
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 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 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.

                       DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1301. APPLICABILITY OF ARTICLE; COMPANY'S OPTION TO EFFECT
                       DEFEASANCE OR COVENANT DEFEASANCE.

         Unless pursuant to Section 301 provision is made for the
inapplicability of either or both of (a) Defeasance of the Securities of a
series under Section 1302 or (b) Covenant Defeasance of the Securities of a
series under Section 1303, then the provisions of such Section or Sections, as
the case may be, together with the other provisions of this Article, shall be
applicable to the Securities of such series, and the Company may at its option
by Board Resolution, at any time, with respect to the Securities of such series,
elect to have either Section 1302 (unless inapplicable) or Section 1303 (unless
inapplicable) be applied to the Outstanding Securities of such series upon
compliance with the applicable conditions set forth below in this Article.

         SECTION 1302. DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of the option provided in Section 1301 to
defease the Outstanding Securities of a particular series, the Company shall be
discharged from its obligations with respect to the Outstanding Securities of
such series on the date the applicable conditions set forth in Section 1304 are
satisfied (hereinafter, "Defeasance"). Defeasance shall mean that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Outstanding Securities of such series and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same); provided, however, that the
following rights, obligations, powers, trusts, duties and immunities shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of Outstanding Securities of such series to receive, solely from the
trust fund provided for in Section 1304, payments in respect of the principal of
(and premium, if any) and interest on such Securities when such payments are
due, (B) the Company's obligations with respect to such Securities under
Sections 304, 305, 306, 1002 and 1009, (C) the rights, powers, trusts, duties
and immunities of the Trustee hereunder and (D) this Article. Subject to
compliance with this Article, the Company may exercise its option with respect
to Defeasance under this Section 1302 notwithstanding the prior exercise of its
option with respect to Covenant Defeasance under Section 1303 in regard to the
Securities of such series.

         SECTION 1303. COVENANT DEFEASANCE.

         Upon the Company's exercise of the option provided in Section 1301 to
obtain a Covenant Defeasance with respect to the Outstanding Securities of a
particular series, the Company shall be released from its obligations under this
Indenture (except its obligations under Sections 304, 305, 306, 506, 509, 610,
1001, 1002, 1006, 1008 and 1009) with respect to the Outstanding Securities of
such series on and after the date the applicable conditions set forth in Section
1304 are satisfied (hereinafter, "Covenant Defeasance"). Covenant Defeasance
shall mean that, with respect to the Outstanding Securities of such series, the
Company may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in this Indenture (except its
obligations under Sections 304, 305, 306, 506, 509, 610, 1001, 1002, 1006, 1008
and 1009), whether directly or indirectly by reason of any reference elsewhere
herein or by reason of any reference to any other provision herein or in any
other document, and such omission to comply shall not constitute an Event of
Default under Section 501(4) with respect to Outstanding Securities of such
series, and the remainder of this Indenture and of the Securities of such series
shall be unaffected thereby.

         SECTION 1304. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to Defeasance under Section 1302
and Covenant Defeasance under Section 1303 with respect to the Outstanding
Securities of a particular series:

         (1) the Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 609 who shall agree to comply with the provisions of this Article
applicable to it), under the terms of an irrevocable trust agreement in form and
substance reasonably satisfactory to

                                                          
                                       47

   55



such Trustee, as trust funds in trust for the purpose of making the following
payments, specifically pledged as security for, and dedicated solely to, the
benefit of the Holders of such Securities, (A) Dollars in an amount, or (B) U.S.
Government Obligations which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms will provide, not
later than the due date of any payment, money in an amount, or (C) a combination
thereof, in each case sufficient, after payment of all federal, state and local
taxes or other charges or assessments in respect thereof payable by the Trustee,
in the opinion of 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 other qualifying
trustee) to pay and discharge, (i) the principal of (and premium, if any, on)
and each installment of principal of (and premium, if any) and interest on the
Outstanding Securities of such series on the Stated Maturity of such principal
or installment of principal or interest and (ii) any mandatory sinking fund
payments or analogous payments applicable to the Outstanding Securities of such
series on the day on which such payments are due and payable in accordance with
the terms of this Indenture and of such Securities.

         (2) No Default or Event of Default with respect to the Securities of
such series shall have occurred and be continuing on the date of such deposit or
shall occur as a result of such deposit, and no Default or Event of Default
under clause (5) or (6) of Section 501 hereof shall occur and be continuing, at
any time during the period ending on the 31st day after the date of such deposit
(it being understood that this condition shall not be deemed satisfied until the
expiration of such period).

         (3) Such deposit, Defeasance or Covenant Defeasance shall not result in
a breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

         (4) Such Defeasance or Covenant Defeasance shall not cause any
Securities of such series then listed on any national securities exchange
registered under the Exchange Act to be delisted.

         (5) In the case of an election with respect to Section 1302, the
Company shall have delivered to the Trustee either (A) a ruling directed to the
Trustee received from the Internal Revenue Service to the effect that the
Holders of the Outstanding Securities of such series will not recognize income,
gain or loss for federal income tax purposes as a result of such Defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Defeasance had not
occurred or (B) an Opinion of Counsel, based on such ruling or on a change in
the applicable federal income tax law since the date of this Indenture, in
either case to the effect that, and based thereon such opinion shall confirm
that, the Holders of the Outstanding Securities of such series will not
recognize income, gain or loss for federal income tax purposes as a result of
such Defeasance and will be subject to federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
Defeasance had not occurred.

         (6) In the case of an election with respect to Section 1303, the
Company shall have delivered to the Trustee an Opinion of Counsel or a ruling
directed to the Trustee received from the Internal Revenue Service to the effect
that the Holders of the Outstanding Securities of such series will not recognize
income, gain or loss for federal income tax purposes as a result of such
Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Covenant Defeasance had not occurred.

         (7) Such Defeasance or Covenant Defeasance shall be effected in
compliance with any additional terms, conditions or limitations which may be
imposed on the Company in connection therewith pursuant to Section 301.

         (8) The Company shall have delivered to the Trustee an Officer's
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the Defeasance under Section 1302 or
the Covenant Defeasance under Section 1303 (as the case may be) have been
complied with.

                                    TO BE HELD IN TRUST.

         Subject to the provisions of the last paragraph of Section 1009, all
money and Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee--collectively for purposes of this
Section 1305, the "Trustee") pursuant to Section 1304 in respect of the
Outstanding Securities of a particular series shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1304 or the principal and interest received in respect
thereof, other than any such tax, fee or other charge which by law is for the
account of the Holders of the Outstanding Securities of such series.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver to pay to the Company from time to time upon Company Request any
money or Government Obligations held by it as provided in Section 1304 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited for
the purpose for which such money or Government Obligations were deposited.
