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

where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein

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

   every purpose hereunder if made, given, furnished or filed in writing to or

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. Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

<PAGE>
                                     11

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

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

Securities of this series as contemplated by [Clause (2) of] the preceding
paragraph as a part of, or in anticipation of, any refunding operation by the
application, directly or indirectly, of moneys borrowed having an interest cost

Securities of this series and of like tenor for the unredeemed portion hereof

SUBJECT TO THE PROVISIONS OF THE INDENTURE, THE HOLDER OF THIS SECURITY IS
ENTITLED, AT ITS OPTION, AT ANY TIME ON OR BEFORE [INSERT DATE] (except that, in
case this Security or any portion hereof shall be called for redemption, such
right shall terminate with respect to this Security or portion hereof, as the
case may be, so called for redemption at the close of business on the date fixed
for redemption as provided in the Indenture unless the Company defaults in
making the payment due upon redemption), to convert the principal amount of this
Security (or any portion hereof which is [INSERT MINIMUM DENOMINATION] or an
integral multiple thereof), into fully paid and non-assessable shares
(calculated as to each conversion to the nearest 1/100th of a share) of the
Common Stock of the Company, as said shares shall be constituted at the date of
conversion, at the conversion price of $    principal amount of Securities for
each share of Common Stock, or at the adjusted conversion price in effect at the
date of conversion determined as provided in the Indenture, upon surrender of
this Security, together with the conversion notice hereon duly executed, to the
Company at the designated office or agency of the Company in      , accompanied
(if so required by the Company) by instruments of transfer, in form satisfactory
to the Company and to the Trustee, duly executed by the Holder or by its duly
authorized attorney in writing. Such surrender shall, if made during any period
beginning at the close of business on a Regular Record Date and ending at the
opening of business on the Interest Payment Date next following such Regular
Record Date (unless this Security or the portion being converted shall have been
called for redemption on a Redemption Date during such period), also be
accompanied by payment in funds acceptable to the Company of an amount equal to
the interest payable on such Interest Payment Date on the principal amount of
this Security then being converted. Subject to the aforesaid requirement for
payment and, in the case of a conversion after the Regular Record Date next
preceding any Interest Payment Date and on or before such Interest Payment Date,
to the right of the Holder of this Security (or any Predecessor Security) of
record at such Regular Record Date to receive an installment of interest (with
certain exceptions provided in the Indenture), no adjustment is to be made on
conversion for interest accrued hereon or for dividends on shares of Common
Stock issued on conversion. The Company is not required to issue fractional
shares upon any such conversion, but shall make adjustment therefor in cash on
the basis of the current market value of such fractional interest as provided in
the Indenture. The conversion price is subject to adjustment as provided in the
Indenture. In addition, the Indenture provides that in case of certain
consolidations or mergers to which the Company is a party or the sale of
substantially all of the assets of the Company, the Indenture shall be amended,
without the consent of any Holders of Securities, so that this Security, if then
outstanding, will be convertible thereafter, during the period this Security
shall be convertible as specified above, only into the kind and amount of
securities, cash and other

Security might have been converted immediately prior to such consolidation,
merger or sale (assuming such holder of Common Stock failed to exercise any
rights or election and received per share the kind and amount received per share
by a plurality of non-electing shares) [, assuming if such consolidation, merger
or sale is prior to       , 19 , that this Security was convertible at the time
of such consolidation, merger or sale at the initial conversion price specified
above as adjusted from       , 19 , to such time pursuant to the Indenture]. In
the event of conversion of this Security in part only, a new Security or
Securities for the unconverted portion hereof shall be issued in the name of the
Holder hereof upon the cancellation hereof.]

   [IF THE SECURITY IS NOT AN ORIGINAL ISSUE DISCOUNT SECURITY,--If an Event of
Default with respect to Securities of this series shall occur and be continuing,

the Company's obligations in respect of the payment of the principal of and
premium and interest, if any, on the Securities of this series shall terminate.]


   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 66 2/3% in principal amount of the Securities at the
time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor 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-rates], and in the coin
or currency, herein prescribed.

forth, the transfer of this Security is registrable in the Security Register,

and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

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

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

   Prior to due presentment of this Security for registration of transfer, the
Company, the 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.

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

Officers' Certificate setting forth the terms of the Securities of such series.

SECTION 302.  DENOMINATIONS.

<PAGE>
                                     25

SECTION 303.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

   The Securities shall be executed on behalf of the Company by its 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.

   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 deliver such Securities. 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 at the time of the initial delivery by the Company of
Securities of such series to the Trustee for authentication, and (subject to
Section 601) 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;

      (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; and

      (c) that such Securities (when executed by the Company, authenticated by
   the Trustee and delivered against payment therefor by the purchasers thereof)
   and the supplemental indenture, if any, (when executed and delivered by the
   Company and the Trustee), will constitute valid and legally binding
   obligations of the Company enforceable in accordance with their terms, except
   to the extent that enforcement thereof may be limited by (1) bankruptcy,
   insolvency, reorganization, moratorium or other similar laws now or hereafter
   in effect relating to creditors' rights generally and (2) general principles
   of equity (regardless of whether enforcement is sought in a proceeding at law
   or in equity).

   After any such first delivery, any separate request by the Company that the
Trustee authenticate Securities of such series for original issue will be deemed
to be a certification by

<PAGE>

                                      26

the Company that all conditions precedent provided for in this Indenture
relating to the authentication and delivery of such Securities continue to have
been complied with.

     The Trustee may, but shall not be obligated to, authenticate the Securities
of any series the form or terms of which have been so established and with
respect to which it would not be or have been obligated, pursuant to the second
sentence of Section 903, to execute, at the time such authentication is
requested (if no Securities of such series have been authenticated) or at the
time of the initial authentication of Securities of such series (if Securities
of such series have been authenticated), an indenture supplemental hereto
containing such form or terms.

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

     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. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, for all purposes of this Indenture such Security shall be deemed never
to have been authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

SECTION 304.  TEMPORARY SECURITIES.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities 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, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

<PAGE>

                                      27

     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 designated pursuant to Section 1002 in a Place
of Payment for Securities of that series, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like aggregate principal amount of definitive Securities of
the same series and of like tenor of authorized denominations. 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.

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 maintained pursuant to Section 1002 for such
purpose 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 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 maintained pursuant to Section 1002 for
such purpose in a Place of Payment for Securities of that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of like
tenor of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.

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

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations 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

<PAGE>

                                      28

written instrument of transfer in form satisfactory to the Company and the
Security Registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company 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 any Security 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 such series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

     Notwithstanding the foregoing, any Global Security shall be exchangeable
pursuant to this Section 305 for Securities registered in the names of Persons
other than the Depositary for such Security or its nominee only if (i) such
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security or if at any time such Depositary ceases to
be a clearing agency registered under the Securities Exchange Act of 1934, as
amended, (ii) the Company executes and delivers to the Trustee a Company Order
that such Global Security shall be so exchangeable or (iii) there shall have
occurred and be continuing an Event of Default with respect to the Securities.
Any Global Security that is exchangeable pursuant to the preceding sentence
shall be exchangeable for Securities registered in such names as such Depositary
shall direct.

     Notwithstanding any other provision in this Indenture, a Global Security
may not be transferred except as a whole by the Depositary with respect to such
Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.

SECTION 306.  MUTILATED, DESTROYED, LOST OR 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

<PAGE>

                                      29

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 of the same series, pay such Security.

     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.

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

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

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

<PAGE>

                                      30

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

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

     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.

     Subject to the provisions of Section 1402, in the case of any Security
which is converted after any Regular Record Date and on or prior to the next
succeeding Interest Payment Date (other than any Security, the principal of (or
premium, if any, on) which shall become due and payable, whether at a Stated
Maturity or by declaration of acceleration, call for redemption, or otherwise,
prior to such Interest Payment Date), interest whose Stated Maturity is on such
Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion, and such interest (whether or not punctually
paid or duly provided for) 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 such Regular Record Date. Except as otherwise expressly provided in
the immediately preceding sentence, in the case of any Security which is
converted, interest whose Stated Maturity is after the date of conversion of
such Security shall not be payable.

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.

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 may deliver to the Trustee (or to any other Person for delivery to the
Trustee) for cancellation any Securities previously authenticated hereunder
which the Company has not issued and sold, and all Securities so delivered shall
be promptly cancelled by the Trustee. No Securities shall be authenticated in
lieu of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of as directed by a Company Order.

SECTION 310.  COMPUTATION OF INTEREST.

     Except as otherwise specified as contemplated by Section 301 for Securities
of any series, interest on the Securities of each series shall be computed on
the basis of a 360-day year of twelve 30-day months.

SECTION 401.  TERMINATION OF COMPANY'S OBLIGATIONS.

     (a) The Company may terminate its obligations under the Securities of any
series and this Indenture (with respect to such series) if:

     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 1003) have been delivered to the Trustee for
     cancellation and the Company has paid all sums payable by it hereunder; or

     deposited or caused to be deposited with the Trustee or Paying Agent and
     conveyed all right, title and interest for the benefit of the Holders of

     agreement in form and substance satisfactory to the Trustee, as trust funds
     in trust solely for the benefit of the Holders of Securities of such series
     for that purpose, money or U.S. Government Obligations (or any combination
     thereof) maturing as to principal and interest in such amounts and at such
     times as are sufficient (in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee) to pay principal of, premium, if any, and
     interest on the Outstanding Securities of such series to redemption or
     maturity; provided, that the Trustee or Paying Agent shall have been
     irrevocably instructed to apply such money or the proceeds of such U.S.
     Government Obligations to the payment of said principal, premium, if any,
     and interest with respect to the Securities of such series (such funds are
     referred to in this Section 401 as the "defeasance trust funds");

          (ii)  The Company paid or caused to be paid all other sums payable
     hereunder by the Company; and

          (iii) The Company delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture with respect to the Securities of such series have been complied
     with; or

          (3)  (A) the Company has irrevocably deposited or caused to be
     deposited with the Trustee or Paying Agent and conveyed all right, title
     and interest for the benefit of the Holders of Securities of such series

<PAGE>

               (B) 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;

               (C) 123 days pass after the deposit is made and during the
          123-day period no Default specified in Section 501(6) or 501(7) occurs
          which is continuing at the end of such period;

               (D) such deposit does not constitute a default under any other
          agreement binding on the Company or its Subsidiaries;

               (E) the Company has paid or caused to be paid all sums then
          payable by the Company hereunder and under the Securities of such

          conflicting interest for purposes of the Trust Indenture Act with
          respect to any securities of the Company;

               (H) the Company shall have delivered to the Trustee an Opinion of
          Counsel stating that neither the Trustee nor the trust fund as a
          result of such deposit will be an "investment company" required to be
          registered under the Investment Company Act of 1940, as amended; and

               (I) the Company has elected to be governed by either Section
          401(b) or 401(c) below.

     (b) The Company may terminate all of its obligations under this Indenture
("legal defeasance"), with respect to such series of Securities and shall be
discharged from such obligations upon compliance by the Company with all of the
conditions set forth above in items (A)-(H), inclusive, of clause (3) of Section
401(a) and upon delivery by the Company to the Trustee of (x) a ruling from the
Internal Revenue Service or (y) an Opinion of Counsel, in either case 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; PROVIDED, HOWEVER, that in the case of either
clause (2) or (3) of Section 401(a), (x) the Company's obligations in Sections
305, 306, 308, 403, 404, 601, 603, 607, 610, 611 and 1003 with respect to such
series of Securities shall survive until the Securities of such series are no
longer outstanding and (y) after the Securities of such series are no longer
outstanding, only the Company's obligations in Sections 607, 403 and 404 with
respect to such series of Securities shall survive.

<PAGE>

                                      34

     The Company may effect legal defeasance notwithstanding any prior covenant
defeasance as set forth in Section 401(c) below.

     (c) The Company may terminate its obligations ("covenant defeasance") under
Sections 801(3) and 1004-1008 in their entireties, Section 501(4), with respect
to violations of Sections 801(3) and 1004-1008, and Section 501(5) in its
entirety, with respect to such series of Securities and shall be discharged from
such obligations upon compliance by the Company with all of the conditions set

Revenue Service or (y) an Opinion of Counsel, in either case 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.

     (d) After any irrevocable deposit as specified in Section 401(a), and
satisfaction of the applicable conditions set forth in Sections 401(a), (b) or
(c), the Trustee, on demand of and at the expense of the Company, shall
acknowledge in writing the discharge of the Company's obligations or certain
covenants under the Securities of such series, as applicable, and such other
appropriate documentation as the Company shall request, and this Indenture with
respect thereto except for those surviving obligations specified above.

SECTION 402.  APPLICATION OF TRUST MONEY.

     The Trustee or Paying Agent shall hold in trust money or U.S. Government
Obligations deposited with it pursuant to Section 401, and shall apply the
deposited money and the money from U.S. Government Obligations in accordance
with this Indenture to the payment of principal of, premium, if any, and
interest on the Securities of the applicable series. Money deposited pursuant to
this section not in violation of this Indenture shall not be subject to claims

to the Company upon written request any excess money or securities held by them
at any time including any such excess money as shall result from interest earned
on the money or the U.S. Government Obligations held by the Trustee or Paying
Agent.

     The Trustee and the Paying Agent shall pay to the Company upon written
request any money held by them for the payment of principal or interest that
remains unclaimed for two years. After payment to the Company, any Holder of
Securities entitled to the money must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another person.

SECTION 404.  REINSTATEMENT.

     If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 401 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture (with respect to such series) and the
Securities of the applicable series shall be revived and reinstated as though no
deposit had occurred pursuant to Section 401 until such time as the Trustee or
Paying Agent is permitted to apply all such money or U.S. Government Obligations
in accordance with section 401; provided, that if the Company has made any
payment of principal of, premium, if any, or interest on any Securities because
of the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Securities to receive such payment from the money
or U.S. Government Obligations held by the Trustee or Paying Agent.

SECTION 501.  EVENTS OF DEFAULT.

     Unless otherwise specified as contemplated in Section 301 or in a
supplemental indenture relating to the Securities of any series, "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 occasioned by the provisions of Article Thirteen or be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

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

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

          (3) default in the deposit of any sinking fund payment, when and as
     due by the terms of a Security of that series; or

          (4) default in the performance, or breach, of any covenant or warranty
     of the Company in this Indenture (other than a covenant or warranty, a
     default in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of Securities of any series other than
     that series), and continuance of such default or breach for a period of 60
     days after there has

<PAGE>

                                      36

     been given, by registered or certified mail, to the Company by the
     Trustee or to the Company and the Trustee by the Holders of at
     least 10% in principal amount of the Outstanding Securities of that
     series a written notice specifying such default or breach and requiring it
     to be remedied and stating that such notice is a "Notice of Default"
     hereunder; or

          (5) there shall be a default (A) under any bond, debenture, note or
     other evidence of indebtedness for money borrowed by the Company (including
     a default with respect to the Securities of any series other than that
     series) or (B) under any mortgage, indenture or other instrument under
     which there may be issued or by which there may be secured or evidenced any
     indebtedness for money borrowed by the Company or any Restricted Subsidiary
     or (C) under any guarantee of payment by the Company or any Restricted
     Subsidiary of indebtedness for money borrowed, or (D) under any bond,

     payable or accrued liabilities arising in the normal course of business
     which are not overdue by more than 90 days or which are being contested in
     good faith) of the Company or any Restricted Subsidiary whether such
     indebtedness or guarantee now exists or shall hereafter be incurred or
     created, and as a result of such default such indebtedness has, by
     acceleration or otherwise under the terms of such bond, debenture, note,
     mortgage, indenture, guarantee of payment or such other evidence of
     indebtedness, become due prior to its stated maturity; PROVIDED, HOWEVER,
     that a default under this Section 501(5) shall exist only if all such
     defaults relate to such indebtedness or such guarantees with an aggregate
     principal amount in excess of $5,000,000, the acceleration of which has not
     been rescinded or annulled within a period of ten days after there shall
     have been given, by registered or certified mail, notice thereof to the
     Company by the Trustee or to the Company and the Trustee by Holders of at
     least 25% in principal amount of the Securities of any series at that time
     Outstanding; PROVIDED, HOWEVER, that if such default under such indenture
     or instrument 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 Securities of any series at that time Outstanding; and
     PROVIDED, FURTHER, that, subject to the provisions of Sections 601 and 602,
     the Trustee shall not be deemed to have knowledge of such default unless
     either (i) a Responsible Officer of the Trustee shall have actual knowledge
     of such default or (ii) the Trustee shall have received written notice
     thereof from the Company, from any Holder, from the holder of any such
     indebtedness or from the trustee under any such mortgage, indenture or
     other instrument; or

          (6) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company or any Restricted
     Subsidiary in an involuntary case or proceeding under any applicable
     Federal or State bankruptcy, insolvency, reorganization or other similar
     law or (B) a decree or order adjudging the Company or any Restricted
     Subsidiary a bankrupt or insolvent, or approving as properly filed a
     petition seeking reorganization, arrangement, adjustment or composition of
     or in respect of the Company or

     sequestrator or other similar official of the Company or any Restricted
     Subsidiary or of any substantial part of its property, or ordering
     the winding up or liquidation of its affairs, and the continuance of
     any such decree or order for relief or any such other decree or
     order unstayed and in effect for a period of 60 consecutive days; or

          (7) the commencement by the Company or any Restricted Subsidiary of a
     voluntary case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law or of any other
     case or proceeding to be adjudicated a bankrupt or insolvent, or the
     consent by it to the entry of a decree or order for relief in respect of
     the Company or any Restricted Subsidiary in an involuntary case or
     proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or to the commencement of any
     bankruptcy or insolvency case or proceeding against it, or the filing by it
     of a petition or answer or consent seeking reorganization or relief under
     any applicable Federal or State law, or the consent by it to the filing of
     such petition or to the appointment of or taking possession by a custodian,
     receiver, liquidator, assignee, trustee, sequestrator or similar official
     of the Company or any Restricted Subsidiary or of any substantial part of
     its property, or the making by it of an assignment for the benefit of
     creditors, or the admission by it in writing of its inability to pay its
     debts generally as they become due, or the taking of corporate action by
     the Company or any Restricted Subsidiary in furtherance of any such action;
     or

          (8) any other Event of Default provided, pursuant to Section 301, in
     or pursuant to a Board Resolution or indenture supplemental hereto as a
     part of the terms of and as applicable with respect to Securities of that
     series.

     Upon receipt by the Trustee of any notice with respect to a Default
pursuant to this Section 501 with respect to Securities of a series all or part
of which is represented by a Global Security, a record date shall be established
for determining Holders of Outstanding Securities of such series entitled to
join in the delivery of a Notice of Default, which record date shall be at the
close of business on the day the Trustee receives such notice with respect to a
Default. The Holders on such record date, or their duly designated proxies, and
only such Persons, shall be entitled to join in a Notice of Default, whether or
not such Holders remain Holders after such record date; PROVIDED, that unless
Holders of at least 10% in principal amount of the Outstanding Securities of
such series, or their proxies, shall have joined in a Notice of Default prior to
the day which is 90 days after such record date, such notice with respect to a
Default shall automatically and without further action by any Holder be canceled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or a
proxy of a Holder, from giving, after expiration of such 90-day period, a new
notice with respect to a Default identical to a notice with respect to a Default
which has been canceled pursuant to the proviso to the preceding sentence, in
which event a new record date shall be established pursuant to the provisions of
this Section 501.

SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

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

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

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

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

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

               (C) all overdue sinking fund payments with respect to Securities
          of that series and interest thereon at the rate or rates prescribed
          therefor in such Securities,

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

               (E) all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel;

     and

          (2) all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

     Upon receipt by the Trustee of written notice declaring an intention to
accelerate, or rescind and annul an acceleration, with respect to Securities of
a series all or part of which is

<PAGE>

                                      39

represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join
in a notice of acceleration, or rescission and annulment thereof, which
record date shall be at the close of business on the day the Trustee receives
a notice of the intention to accelerate, or rescind and annul an
acceleration. The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in a notice of
acceleration, or rescission and annulment thereof, whether or not such
Holders remain Holders after such record date; PROVIDED, that unless such
declaration of acceleration, or rescission and annulment, as the case may be,
shall have become effective by virtue of the requisite percentage having
joined in a notice of acceleration, or rescission and annulment thereof prior
to the day which is 90 days after such record date, the notice of the
intention to accelerate, or rescind and annul an acceleration, as the case
may be, shall automatically and without further action by any Holder be
canceled and of no further effect. Nothing in this paragraph shall prevent a
Holder, or a proxy of a Holder, from giving, after expiration of such 90-day
period, a new written notice of an intention to accelerate, or rescind and
annul an acceleration, as the case may be, that is identical to a written
notice which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to
the provisions of this Section 502.

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

SECTION 503.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

     The Company covenants that if

          (1) default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 30 days, or

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

          (3) default is made in the deposit of any sinking fund payment, when
     and as due by the terms of a Security of any series,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holder of such Security, the whole amount then due and payable on such Security
for principal (and premium, if any) and interest and for any sinking fund
payment 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 and on any overdue sinking fund payment, at the rate or rates
prescribed therefor in such Security, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

<PAGE>

                                      40

     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 Security 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 Security, wherever
situated.

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

SECTION 504.  TRUSTEE MAY FILE PROOFS OF CLAIM.

     In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized 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.

                                      41

SECTION 506.  APPLICATION OF MONEY COLLECTED.

     Subject to Article Thirteen are the provisions of any supplemented
indenture, any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest or sinking fund payments, upon presentation of the
Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

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

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

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 such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect,

<PAGE>

                                      42

disturb or prejudice the rights of any other of such Holders, or to obtain or
to seek to obtain priority or preference over any other of such Holders or to
enforce any right under this Indenture, except in the manner herein provided
and for the equal and ratable benefit of all of such Holders.

     Upon receipt by the Trustee of written request to the Trustee to institute
proceedings in respect of a continuing Event of Default pursuant to Section
507(2) with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such written request in respect of such Event of Default, which record date
shall be at the close of business on the day the Trustee receives a written
request to institute such proceedings.  The Holders on such record date, or
their duly designated proxies, and only such Persons, shall be entitled to join
in a written request to institute proceedings, whether or not such Holders
remain Holders after such record date; PROVIDED, that unless such written
request shall have become effective by virtue of the requisite percentage having
joined in such written request prior to the day which is 90 days after such
record date, the written request shall automatically and without further action
by any Holder be canceled and of no further effect.  Nothing in this paragraph
shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of
such 90-day period, a new written request to institute proceedings in respect of
such continuing Event of Default, that is identical to a written notice which
has been canceled pursuant to the proviso to the preceding sentence, in which
event a new record date shall be established pursuant to the provisions of this
Section 507.

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)
any interest on such Security on the Stated Maturity or Maturities expressed in
such Security (or, in the case of redemption, on the Redemption Date), to
convert such Securities in accordance with Article Fourteen 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 had been instituted.

<PAGE>

                                      43

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, and

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

     Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such notice, which record date shall be at the close of business on the day the
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
PROVIDED, that unless the Holders of a majority in principal amount of the
Outstanding Securities of such series shall have joined in such notice prior to
the day which is 90 days after such record date, such notice shall automatically
and without further action by any

<PAGE>

                                      44

Holder be canceled and of no further effect. Nothing in this paragraph shall
prevent a Holder, or a proxy of a Holder, from giving, after expiration of
such 90-day period, a new notice identical to a notice which has been
canceled pursuant to the proviso to the preceding sentence, in which event a
new record date shall be established pursuant to the provisions of this
Section 512.

SECTION 513.  WAIVER OF PAST DEFAULTS.

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

          (1) 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 instalment with respect to the Securities of such series, or

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

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

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

SECTION 514.  UNDERTAKING FOR COSTS.

     In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; PROVIDED that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in

<PAGE>

                                      45

any suit instituted by the Company or in any suit for the enforcement of the
right to convert any Security in accordance with Article Fourteen.

SECTION 515.  WAIVER OF STAY OR EXTENSION 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 or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) 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.


                                   ARTICLE SIX

                                   THE TRUSTEE

SECTION 601.  CERTAIN DUTIES AND RESPONSIBILITIES.

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

SECTION 602.  NOTICE OF DEFAULTS.

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

                                      46


SECTION 603.  CERTAIN RIGHTS OF TRUSTEE.

     Subject to the provisions of Section 601:

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

     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (d) the Trustee may consult with counsel and the written advice of
     such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or

          (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 reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

          (f) 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,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney; and

          (g) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or

     it hereunder.

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

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee or any Authenticating Agent assumes no responsibility for their

sufficiency of this Indenture or of the Securities. The Trustee or any

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 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 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);

          (2) except as otherwise expressly provided herein, to reimburse the

     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel), except any such expense,

<PAGE>

                                      48

     claim or liability in connection with the exercise or performance of any of
     its powers or duties hereunder.

     "Trustee" for purposes of this Section 607 shall include each Trustee and
each predecessor trustee, but the negligence or bad faith of any such Person
shall not affect the right of any other such Person under this Section 607.

     The provisions of this Section 607 shall survive this Indenture.

SECTION 608.  CONFLICTING INTERESTS.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

State thereof or the District of Columbia, authorized under such laws to
exercise corporate trust powers, 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 and to the extent permitted by
the Trust Indenture Act, 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. 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.

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

<PAGE>

                                      49

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.

     (d) If at any time:

          (1) the Trustee shall fail to comply with Section 608(a) 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 therefor by the Company or by any such
     Holder, or

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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of 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 the 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. 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,

<PAGE>

                                      50

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

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

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.

     (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 the Securities of all
series for which it is the Trustee hereunder, 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
<PAGE>

                                      51

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
this Article.

SECTION 612.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 613.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

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 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

<PAGE>

                                      52

and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
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 Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

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

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

     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), or modify the provisions of the Indenture
     with respect to the subordination of the Securities in a manner adverse to
     the Holders, or

          (2) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of the Holders of which is required
     for any such supplemental indenture, or the consent of the Holders of which
     is required for any waiver (of compliance with certain provisions of this
     Indenture or certain defaults hereunder and their consequences) provided
     for in this Indenture, or

          (3) modify any of the provisions of this Section, Section 513 or
     Section 1009, 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 and Section 1009 in
     accordance with the requirements of Sections 611(b) and 901(8), or the
     deletion of this proviso, or

          (4) make any change that adversely affects the right to convert any
     Security as provided in Article Fourteen or pursuant to Section 301 (except
     as permitted by Section 901(9)) or decrease the conversion rate or increase
     the conversion price of any such Security.

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has 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.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to consent to any indenture
supplemental hereto. If a record date is fixed, the Holders on such record date,
or their duly designated proxies, and only such Persons, shall be entitled to
consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; PROVIDED, that unless such consent shall have
become effective by virtue of the requisite percentage having been obtained
prior to the date which is

<PAGE>

                                      59

90 days after such record date, any such consent previously given shall
automatically and without further action by any Holder be canceled and of no
further effect.

     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.

     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
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture and that all conditions precedent in
the Indenture have been complied with. 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 authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

                                    COVENANTS

SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities of such series and this Indenture.

SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where Securities of that series may be
surrendered for conversion and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served,
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. With respect to the Securities of
any series, such office or agency and each Place of Payment shall be as
specified as contemplated by Section 301. In the absence of any such provisions
with respect to the Securities of any series, the Place of Payment for such
Securities shall initially be the Corporate Trust Office. The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; PROVIDED, HOWEVER, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

                                      61

SECTION 1003.  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 as provided by the Trust Indenture Act 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 so to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will:

          (1) 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;

          (2) 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

          (3) 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

<PAGE>

                                      62

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 or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause
to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in the
Borough of Manhattan, The City of New York, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less
than 30 days from the date of such publication, any unclaimed balance of such
money then remaining will be repaid to the Company.

SECTION 1004.  CORPORATE EXISTENCE.

     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; PROVIDED, HOWEVER,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

SECTION 1005.  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 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 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.

SECTION 1006.  LIMITATION UPON SALES OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES.

     The Company will not sell, transfer or otherwise dispose of (except to a
Restricted Subsidiary or for directors' qualifying shares), and it will not
permit any Restricted Subsidiary to sell, transfer or otherwise dispose of
(except to the Company or to a Restricted Subsidiary or for directors'
qualifying shares) any shares of capital stock of a Restricted Subsidiary,
unless the entire capital stock of such Restricted Subsidiary at the time owned
by the Company and its Restricted Subsidiaries shall be disposed of at the same
time for a consideration consisting of cash or other property, which, in the
opinion of the Board of Directors, is at least equal to the fair value thereof.

<PAGE>

                                      63

SECTION 1007.  LIMITATION UPON CREATION OF LIENS ON CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES.

     The Company will not, and it will not permit any Restricted Subsidiary at
any time directly or indirectly to, create, assume, incur or permit to exist any
indebtedness secured by a pledge, lien or other encumbrance on the capital stock
of any Restricted Subsidiary without making effective provision whereby the
Securities then outstanding (and, if the Company so elects, any other
indebtedness ranking on a parity with the Securities) shall be equally and
ratably secured with such secured indebtedness so long as such other
indebtedness shall be secured.

     If the Company shall hereafter be required to secure the Securities equally
and ratably with any other indebtedness pursuant to this Section, (i) the
Company will promptly deliver to the Trustee an Officers' Certificate stating
that the foregoing covenant has been complied with, and  an Opinion of Counsel
stating that in the opinion of such counsel the foregoing covenant has been
complied with and that any instruments executed by the Company or any Restricted
Subsidiary in the performance of the foregoing covenant comply with the
requirements of the foregoing covenants and (ii) the Trustee is hereby
authorized to enter into an indenture or agreement supplemental hereto and to
take such action, if any, as it may deem advisable to enable it to enforce the
rights of the holders of the Securities so secured.

SECTION 1008.  STATEMENT BY OFFICERS AS TO DEFAULT.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of Sections 1001 to 1007, inclusive, and if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.

SECTION 1009.  WAIVER OF CERTAIN COVENANTS.

     The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Sections 1002 and 1004 to 1007, inclusive,
with respect to the Securities of any series if before the time for such
compliance the Holders of at least 66-2/3% in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition 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 term, provision or
condition shall remain in full force and effect.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to waive any such term, provision or
condition. If a record date is fixed, the Holders on such record date, or their
duly designated proxies, and only such

<PAGE>

                                      64

Persons, shall be entitled to waive any such term, provision or condition
hereunder, whether or not such Holders remain Holders after such record date;
PROVIDED, that unless the Holders of at least 66-2/3% in principal amount of
the Outstanding Securities of such series shall have waived such term,
provision or condition prior to the date which is 90 days after such record
date, any such waiver previously given shall automatically and without
further action by any Holder be canceled and of no further effect.


                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

SECTION 1101.  APPLICABILITY OF ARTICLE.

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

SECTION 1102.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The election of the Company to redeem any Securities of any series pursuant
to Section 1101 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 60 days prior to the Redemption Date fixed
by the Company (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee of such Redemption Date 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 Officers' Certificate evidencing
compliance with such restriction.

SECTION 1103.  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

     If any Security selected for partial redemption is converted in part before
termination of the conversion right with respect to the portion of the Security
so selected, the converted portion of

<PAGE>

                                      65

such Security shall be deemed (so far as may be) to be the portion selected
for redemption. Securities which have been converted during a selection of
Securities to be redeemed shall be treated by the Trustee as Outstanding for
the purpose of such selection. In any case where more than one Security is
registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Security.

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

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

SECTION 1104.  NOTICE OF REDEMPTION.

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

     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 of such series to be
     redeemed,

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

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

          (6) that the redemption is pursuant to a sinking fund requirement, if
     such is the case, and

<PAGE>

                                      66

          (7) if applicable, the conversion price, the date on which the right
     to convert the Securities to be redeemed will terminate and the place or
     places where such Securities may be surrendered for conversion.

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

SECTION 1105.  DEPOSIT OF REDEMPTION PRICE.

     Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date in which event, interest shall be separately
payable) 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 instalments 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 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 therefor in the
Security.

SECTION 1107.  SECURITIES REDEEMED IN PART.

     Any Security which is to be redeemed only in part shall be surrendered at
the office or agency of the Company maintained pursuant to Section 1002 for such
purpose as a Place of Payment for Securities of that series (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing), and the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and of like tenor

<PAGE>

                                      67

and 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.

     If a Global Security is so surrendered, such new Security so issued shall
be a new Global Security.


                                 ARTICLE TWELVE

                                  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 reduction 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 Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been 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 Securities, 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.

<PAGE>

                                      68

SECTION 1203.  REDEMPTION OF SECURITIES FOR SINKING FUND.

     Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 45 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. The Company shall deposit the
amount of cash, if any, required for such sinking fund payment with the Trustee
in the manner provided in Section 1105. 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.

Section 301 the Company covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article, the indebtedness
represented by the Securities and the payment of the principal of (and premium,
if any) and interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness.

SECTION 1302.  PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

     In the event of (a) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relative to the Company or to its creditors, as such, or

such event the holders of Senior Indebtedness shall be entitled to receive
payment in full of all amounts due or to become due on or in respect of all
Senior Indebtedness, or provision shall be made for such payment in money or
money's worth, before the Holders of the Securities are entitled to receive any
payment on account of principal of (or premium, if any) or interest on the
Securities, and

<PAGE>

                                      69

to that end the holders of Senior Indebtedness shall be entitled to receive,
for application to the payment thereof, any payment or distribution of any
kind or character, whether in cash, property or securities, which may be
payable or deliverable in respect of the Securities in any such case,
proceeding, dissolution, liquidation or other winding up or event.

     In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, before all Senior Indebtedness is paid
in full or payment thereof provided for, and if such fact shall, at or prior to
the time of such payment or distribution, have been made known to the Trustee
or, as the case may be, such Holder, then and in such event such payment or
distribution shall be paid over or delivered forthwith to the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other
Person making payment or distribution of assets of the Company for application
to the payment of all Senior Indebtedness remaining unpaid, to the extent
necessary to pay all Senior Indebtedness in full, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.


     For purposes of this Article only, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment which are subordinated in right of
payment to all Senior Indebtedness which may at the time be outstanding to
substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article. The consolidation of the
Company with, or the merger of the Company into, another Person or the
liquidation or dissolution of the Company following the conveyance or transfer
of its properties and assets substantially as an entirety to another Person upon
the terms and conditions set forth in Article Eight shall not be deemed a
dissolution, winding up, liquidation, reorganization, assignment for the benefit
of creditors or marshalling of assets and liabilities of the Company for the
purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or which acquires by conveyance or transfer such
properties and assets substantially as an entirety, as the case may be, shall,
as a part of such consolidation, merger, conveyance or transfer, comply with the
conditions set forth in Article Eight.

SECTION 1303.  PRIOR PAYMENT TO SENIOR INDEBTEDNESS UPON ACCELERATION OF
SECURITIES.

     In the event that any Securities are declared due and payable before their
Stated Maturity, then and in such event the holders of the Senior Indebtedness
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all amounts due or to become due on or in
respect of all Senior Indebtedness, or provision shall be made for such payment
in money or money's worth before the Holders of the Securities are entitled to
receive any payment by the Company on account of the principal of (or premium,
if any) or interest on the Securities or on account of the purchase or other
acquisition of Securities; PROVIDED, HOWEVER, that nothing in this Section shall
prevent the satisfaction of any sinking fund

<PAGE>

                                      70

payment in accordance with Article Twelve by delivering and crediting pursuant
to Section 1202 Securities which have been acquired (upon redemption or
otherwise) prior to such declaration of acceleration or which have been
converted pursuant to Article Fourteen.

     In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

     The provisions of this Section shall not apply to any payment with respect
to which Section 1302 would be applicable.

SECTION 1304.  NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.

     (a) In the event and during the continuation of any default in the payment
of principal of (or premium, if any) or interest on any Senior Indebtedness
during or beyond any applicable grace period with respect thereto, or in the
event that any default with respect to any Senior Indebtedness shall have
occurred and be continuing permitting the holders of such Senior Indebtedness
(or a trustee on behalf of the holders thereof) to declare such Senior
Indebtedness due and payable prior to the date on which it would otherwise have
become due and payable, unless and until such default shall have been cured or
waived or shall have ceased to exist and, if any such Senior Indebtedness shall
have been accelerated, such acceleration shall have been rescinded or annulled,
or (b) in the event any judicial proceeding shall be pending with respect to any
such default, then no payment shall be made by the Company on account of
principal of (or premium, if any) or interest on the Securities or on account of
the purchase or other acquisition of Securities; PROVIDED, HOWEVER, that nothing
in this Section shall prevent the satisfaction of any sinking fund payment in
accordance with Article Twelve by delivering and crediting pursuant to Section
1202 Securities which have been acquired (upon redemption or otherwise) prior to
such declaration of acceleration or which have been converted pursuant to
Article Fourteen.

     In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

     The provisions of this Section shall not apply to any payment with respect
to which Section 1302 would be applicable.

<PAGE>

                                      71

SECTION 1305.  PAYMENT PERMITTED IF NO DEFAULT.

     Nothing contained in this Article or elsewhere in this Indenture or in any
of the Securities shall prevent (a) the Company, at any time except during the
pendency of any case, proceeding, dissolution, liquidation or other winding up,
assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 1302 or under the conditions
described in Section 1303 or 1304, from making payments at any time of principal
of (and premium, if any) or interest on the Securities, or (b) the application
by the Trustee of any money deposited with it hereunder to the payment of or on
account of the principal of (and premium, if any) or interest on the Securities
or the retention of such payment by the Holders, if, at the time of such
application by the Trustee, it did not have knowledge that such payment would
have been prohibited by the provisions of this Article.

SECTION 1306.  SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.

     Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of (and
premium, if any) and interest on the Securities shall be paid in full. For
purposes of such subrogation, no payments or distributions to the holders of the
Senior Indebtedness of any cash, property or securities to which the Holders of
the Securities or the Trustee would be entitled except for the provisions of
this Article, and no payments over pursuant to the provisions of this Article to
the holders of Senior Indebtedness by Holders of the Securities or the Trustee,
shall, as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.

SECTION 1307.  PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

     The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article of the holders of Senior Indebtedness, is intended to rank
equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of (and premium, if any) and interest on
the Securities as and when the same shall become due and payable in accordance
with their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the

<PAGE>

                                      72

rights, if any, under this Article of the holders of Senior Indebtedness to
receive cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder.

SECTION 1308.  TRUSTEE TO EFFECTUATE SUBORDINATION.

     Each Holder of a Security by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination provided in this Article and appoints the
Trustee his attorney-in-fact for any and all such purposes.

SECTION 1309.  NO WAIVER OF SUBORDINATION PROVISIONS.

     No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Trustee or the Holders of the Securities,
without incurring responsibility to the Holders of the Securities and without
impairing or releasing the subordination provided in this Article or the
obligations hereunder of the Holders of the Securities to the holders of Senior
Indebtedness, do any one or more of the following: (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness
or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise dispose
of any property pledged, mortgaged or otherwise securing Senior Indebtedness;
(iii) release any Person liable in any manner for the collection of Senior
Indebtedness; and (iv) exercise or refrain from exercising any rights against
the Company and any other Person.

SECTION 1310.  NOTICE TO TRUSTEE.

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee therefor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 601, shall be entitled in all

<PAGE>

                                      73

respects to assume that no such facts exist; PROVIDED, HOWEVER, that if the
Trustee shall not have received the notice provided for in this Section at
least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of (and premium, if any) or interest on any
Security), then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such money and to
apply the same to the purpose for which such money was received and shall not
be affected by any notice to the contrary which may be received by it within
two Business Days prior to such date.

     Subject to the provisions of Section 601, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
to be a holder of Senior Indebtedness (or a trustee therefor) to establish that
such notice has been given by a holder of Senior Indebtedness (or a trustee
therefor). In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

SECTION 1311.  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

     Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 601, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article.


SECTION 1312.  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS.

     The Trustee, in its capacity as trustee under this Indenture, shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall
not be liable to any such holders if it shall in good faith mistakenly pay over
or distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Indebtedness shall
be entitled by virtue of this Article or otherwise.

<PAGE>

                                      74

SECTION 1313.  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS; PRESERVATION
OF TRUSTEE'S RIGHTS.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness which may at
any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

     Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.

SECTION 1314.  ARTICLE APPLICABLE TO PAYING AGENTS.

     In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; PROVIDED, HOWEVER, that
Section 1313 shall not apply to the Company or any Affiliate of the Company if
it or such Affiliate acts as Paying Agent.

SECTION 1315.  CERTAIN CONVERSIONS DEEMED PAYMENT.

     For the purposes of this Article only, (1) the issuance and delivery of
junior securities upon conversion of Securities in accordance with Article
Fourteen shall not be deemed to constitute a payment or distribution on account
of the principal of or premium or interest on Securities or on account of the
purchase or other acquisition of Securities, and (2) the payment, issuance or
delivery of cash, property or securities (other than junior securities) upon
conversion of a Security shall be deemed to constitute payment on account of the
principal of such Security. For the purposes of this Section, the term "junior
securities" means (a) shares of any stock of any class of the Company and (b)
securities of the Company which are subordinated in right of payment to all
Senior Indebtedness which may be outstanding at the time of issuance or delivery
of such securities to substantially the same extent as, or to a greater extent
than, the Securities are so subordinated as provided in this Article. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the right,
which is absolute and unconditional, of the Holder of any Security to convert
such Security in accordance with Article Fourteen.

                                ARTICLE FOURTEEN

                            CONVERSION OF SECURITIES

SECTION 1401.  APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to the Securities of any
series which are convertible into shares of Common Stock of the Company, and the
issuance of such shares of Common Stock upon the conversion of such Securities,
except as otherwise specified as contemplated by Section 301 for the Securities
of such series.

SECTION 1402.  EXERCISE OF CONVERSION PRIVILEGE.

     In order to exercise a conversion privilege, the Holder of a Security of a
series with such a privilege shall surrender such Security to the Company at the
office or agency maintained for that purpose pursuant to Section 1002,
accompanied by written notice to the Company that the Holder elects to convert
such Security or a specified portion thereof. Such notice shall also state, if
different from the name or names (with address) in which the Securities are
registered, the name or names in which the certificate or certificates for
shares of Common Stock which shall be issuable on such conversion shall be
issued. Securities surrendered for conversion shall (if so required by the
Company or the Trustee) be duly endorsed by or accompanied by instruments of
transfer in forms satisfactory to the Company and the Trustee duly executed by
the registered Holder or its attorney duly authorized in writing; and Securities
so surrendered for conversion during the period from the close of business on
any Regular Record Date to the opening of business on the next succeeding
Interest Payment Date (excluding Securities or portions thereof called for
redemption during such period) shall also be accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of such Security then being
converted, and such interest shall be payable to such registered Holder
notwithstanding the conversion of such Security, subject to the provisions of
Section 307 relating to the payment of Defaulted Interest by the Company. As
promptly as practicable after the receipt of such notice and of any payment
required pursuant to a Board Resolution and, subject to Section 303, set forth,
or determined in the manner provided, in an Officers' Certificate, or
established in one or more indentures supplemental hereto setting forth the
terms of such series of Security, and the surrender of such Security in
accordance with such reasonable regulations as the Company may prescribe, the
Company shall issue and shall deliver, at the office or agency at which such
Security is surrendered, to such Holder or on its written order, a certificate
or certificates for the number of full shares of Common Stock issuable upon the
conversion of such Security (or specified portion thereof), in accordance with
the provisions of such Board Resolution, Officers' Certificate or supplemental
indenture, and cash as provided therein in respect of any fractional share of
such Common Stock otherwise issuable upon such conversion. Such conversion shall
be deemed to have been effected immediately prior to the close of business on
the date on which such notice and such payment, if required, shall have been
received in proper order for conversion by the Company and such

<PAGE>

                                      76

Security shall have been surrendered as aforesaid (unless such Holder shall
have so surrendered such Security and shall have instructed the Company to
effect the conversion on a particular date following such surrender and such
Holder shall be entitled to convert such Security on such date, in which case
such conversion shall be deemed to be effected immediately prior to the close
of business on such date) and at such time the rights of the Holder of such
Security as such Security Holder shall cease and the person or persons in
whose name or names any certificate or certificates for shares of Common
Stock of the Company shall be issuable upon such conversion shall be deemed
to have become the Holder or Holders of record of the shares represented
thereby. Except as set forth above and subject to the final paragraph of
Section 307, no payment or adjustment shall be made upon any conversion on
account of any interest accrued on the Securities surrendered for conversion
or on account of any dividends on the Common Stock of the Company issued upon
such conversion.

     In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to or on the order of the Holder thereof, at the expense of the Company,
a new Security or Securities of the same series, of authorized denominations, in
aggregate principal amount equal to the unconverted portion of such Security.

SECTION 1403.  NO FRACTIONAL SHARES.

     No fractional share of Common Stock of the Company shall be issued upon
conversions of Securities of any series. If more than one Security shall be
surrendered for conversion at one time by the same Holder, the number of full
shares which shall be issuable upon conversion shall be computed on the basis of
the aggregate principal amount of the Securities (or specified portions thereof
to the extent permitted hereby) so surrendered. If, except for the provisions of
this Section 1403, any Holder of a Security or Securities would be entitled to a
fractional share of Common Stock of the Company upon the conversion of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed, (i) if such Common Stock is listed or admitted to
unlisted trading privileges on a national securities exchange, on the basis of
the last reported sale price regular way on such exchange on the last Trading
Day prior to the date of conversion upon which such a sale shall have been
effected, or (ii) if such Common Stock is not at the time so listed or admitted
to unlisted trading privileges on a national securities exchange, on the basis
of the average of the bid and asked prices of such Common Stock in the over-the-
counter market on the last Trading Day prior to the date of conversion, as
reported by the National Quotation Bureau, Incorporated or similar organization
if the National Quotation Bureau, Incorporated is no longer reporting such
information, or if not so available, the fair market price as determined by the
Board of Directors.

                                      77

SECTION 1404.  ADJUSTMENT OF CONVERSION PRICE.

     The conversion price of Securities of any series that is convertible into
Common Stock of the Company shall be adjusted for any stock dividends, stock
splits, reclassification, combinations or similar transactions in accordance
with the terms of the supplemental indenture or Board Resolution setting forth
the terms of the Securities of such series.

     Whenever the conversion price is adjusted, the Company shall compute the
adjusted conversion price in accordance with terms of the applicable Board
Resolution or supplemental indenture and shall prepare an Officers' Certificate
setting forth the adjusted conversion price and showing in reasonable detail the
facts upon which such adjustment is based, and such certificate shall forthwith
be filed at each office or agency maintained for the purpose of conversion of
Securities pursuant to Section 1002 and, if different, with the Trustee. The
Company shall forthwith cause a notice setting forth the adjusted conversion
price to be mailed, first class postage prepaid, to each Holder of Securities of
such series at its address appearing on the Security Register and to any
conversion agent other than the Trustee.

SECTION 1405.  NOTICE OF CERTAIN CORPORATE ACTIONS.

     In case:

          (a) the Company shall declare a dividend (or any other distribution)
     on its Common Stock payable otherwise than in cash out of its retained
     earnings (other than a dividend for which approval of any shareholders of
     the Company is required); or

          (b) the Company shall authorize the granting to the holders of its
     Common Stock of rights, options or warrants to subscribe for or purchase
     any shares of capital stock of any class or of any other rights (other than
     any such grant for which approval of any shareholders of the Company is
     required); or

          (c) of any reclassification of the Common Stock of the Company (other
     than a subdivision or combination of its outstanding shares of Common
     Stock, or of any consolidation, merger or share exchange to which the
     Company is a party and for which approval of any shareholders of the
     Company is required), or of the sale of all or substantially all of the
     assets of the Company; or

          (d) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company;

then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their last addresses as they shall appear in the
Securities Register, at least 20 days (or 10 days in any case specified in
clause (a) or (b) above) prior to the applicable record date hereinafter
specified, a notice stating (i) the date on which a record is to be taken for
the

<PAGE>

                                      78

purpose of such dividend, distribution, rights, options or warrants, or, if
a record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution, rights, options or
warrants are to be determined, or (ii) the date on which such reclassification,
consolidation, merger, share exchange, sale, dissolution, liquidation or winding
up is expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, dissolution,
liquidation or winding up. If at any time the Trustee shall not be the
conversion agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

SECTION 1406.  RESERVATION OF SHARES OF COMMON STOCK.

     The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock of the Company then issuable upon the conversion of all outstanding
Securities of any series that has conversion rights.

SECTION 1407.  PAYMENT OF CERTAIN TAXES UPON CONVERSION.

     The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of its Common Stock on conversion of Securities
pursuant hereto. The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of its Common Stock in a name other than that of the Holder
of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the person requesting such issue has paid to the
Company the amount of any such tax, or has established, to the satisfaction of
the Company, that such tax has been paid.

SECTION 1408.  NONASSESSABILITY.

     The Company covenants that all shares of its Common Stock which may be
issued upon conversion of Securities will upon issue in accordance with the
terms hereof be duly and validly issued and fully paid and nonassessable.

SECTION 1409.  EFFECT OF CONSOLIDATION OR MERGER ON CONVERSION PRIVILEGE.

     In case of any consolidation of the Company with, or merger of the Company
into or with any other Person, or in case of any sale of all or substantially
all of the assets of the Company, the Company or the Person formed by such
consolidation or the Person into which the Company shall have been merged or the
Person which shall have acquired such assets, as the case may be, shall execute
and deliver to the Trustee a supplemental indenture providing that the Holder of
each Security then outstanding of any series that is convertible into Common
Stock of the

<PAGE>

                                      79

Company shall have the right, which right shall be the exclusive conversion
right thereafter available to said Holder (until the expiration of the
conversion right of such Security), to convert such Security into the kind
and amount of shares of stock or other securities or property (including
cash) receivable upon such consolidation, merger or sale by a holder of the
number of shares of Common Stock of the Company into which such Security
might have been converted immediately prior to such consolidation, merger or
sale, subject to compliance with the other provisions of this Indenture, such
Security and such supplemental indenture. Such supplemental indenture shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in such Security. The above
provisions of this Section shall similarly apply to successive
consolidations, mergers or sales. It is expressly agreed and understood that
anything in this Indenture to the contrary notwithstanding, if, pursuant to
such merger, consolidation or sale, holders of outstanding shares of Common
Stock of the Company do not receive shares of common stock of the surviving
corporation but receive other securities, cash or other property or any
combination thereof, Holders of Securities shall not have the right to
thereafter convert their Securities into common stock of the surviving
corporation or the corporation which shall have acquired such assets, but
rather, shall have the right upon such conversion to receive the other
securities, cash or other property receivable by a holder of the number of
shares of Common Stock of the Company into which the Securities held by such
holder might have been converted immediately prior to such consolidation,
merger or sale, all as more fully provided in the first sentence of this
Section 1409. Anything in this Section 1409 to the contrary notwithstanding,
the provisions of this Section 1409 shall not apply to a merger or
consolidation of another corporation with or into the Company pursuant to
which both of the following conditions are applicable: (i) the Company is the
surviving corporation and (ii) the outstanding shares of Common Stock of the
Company are not changed or converted into any other securities or property
(including cash) or changed in number or character or reclassified pursuant
to the terms of such merger or consolidation.

     As evidence of the kind and amount of shares of stock or other securities
or property (including cash) into which Securities may properly be convertible
after any such consolidation, merger or sale, or as to the appropriate
adjustments of the conversion prices applicable with respect thereto, the
Trustee shall be furnished with and may accept the certificate or opinion of an
independent certified public accountant with respect thereto; and, in the
absence of bad faith on the part of the Trustee, the Trustee may conclusively
rely thereon, and shall not be responsible or accountable to any Holder of
Securities for any provision in conformity therewith or approved by such
independent certified accountant which may be contained in said supplemental
indenture.

to the nature or extent of any such adjustment when made, or

with respect to the method employed, whether herein or in any supplemental
indenture, any resolutions of the Board of Directors or written instrument
executed by one or more officers of the Company provided to be employed in
making the same. Neither the Trustee nor any conversion agent shall be
accountable with respect to the validity or value (or the kind or amount) of
any shares of Common Stock of the Company, or of any Securities and neither
the Trustee nor any conversion agent makes any representation with respect
thereto. Subject to the provisions of Section 601, neither the Trustee nor
any conversion agent shall be responsible for any failure of the Company to
issue, transfer or deliver any shares of its Common Stock or stock
certificates or other securities or property upon the surrender of any
Security for the purpose of conversion or to comply with any of the covenants
of the Company contained in this Article Fourteen or in the applicable
supplemental indenture, resolutions of the Board of Directors or written
instrument executed by one or more duly authorized officers of the Company.

its behalf with the Trustee or any other paying agent for the purpose of paying

Securities (including funds deposited for the sinking fund referred to in
Article Three hereof) and which shall not be required for such purposes because
of the conversion of such Securities as provided in this Article Fourteen shall
after such conversion be repaid to the Company by the Trustee upon the Company's
written request.

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

     In Witness Whereof, the parties hereto have caused this Indenture to be
duly executed, and their respective corporate seals to be hereunto affixed and
attested, all as of the day and year first above written.

     FIRST SUPPLEMENTAL INDENTURE, dated as of May __, 1995, between UNUM
Corporation, a corporation duly organized and existing under the laws of the
State of Delaware (herein called the "Company"), having its principal office at
2211 Congress Street, Portland, Maine 04122, and Mellon Bank, N.A., a national
banking association, as Trustee (herein called the "Trustee") under the
Indenture dated as of May __, 1995 between the Company and the Trustee (the
"Indenture").


                             RECITALS OF THE COMPANY

     The Company has executed and delivered the Indenture to the Trustee to
provide for the issuance from time to time of its unsecured subordinated
debentures, notes or other evidences of indebtedness (the "Securities"), said
Securities to be issued in one or more series as in the Indenture provided.

     Pursuant to the terms of the Indenture, the Company desires to provide for
the establishment of a new series of its Securities to be known as its ___%
Junior Subordinated Deferrable Interest Debentures, Series A, Due 2025 (herein
called the "Series A Debentures"), the form and substance of such Series A
Debentures and the terms, provisions and conditions thereof to be set forth as
provided in the Indenture and this First Supplemental Indenture.

     All things necessary to make this First Supplemental Indenture a valid
agreement of the Company, and to make the Series A Debentures, when executed by
the Company and authenticated and delivered by the Trustee, the valid
obligations of the Company, have been done.

     NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH:

     For and in consideration of the premises and the purchase of the Series A
Debentures by the Holders thereof, and for the purpose of setting forth, as
provided in the Indenture, the form and substance of the Series A Debentures and
the terms, provisions and conditions thereof, it is mutually agreed, for the
equal and proportionate benefit of all Holders of the Series A Debentures, as
follows:


                                   ARTICLE ONE

                         GENERAL TERMS AND CONDITIONS OF
                             THE SERIES A DEBENTURES

     SECTION 101.  There shall be and is hereby authorized a series of
Securities designated the "___% Junior Subordinated Deferrable Interest
Debentures, Series A, Due 2025", limited in aggregate principal amount to
$230,000,000, which amount shall be as set forth in any written order of the
Company for the authentication and delivery of Series A Debentures. The Series A
Debentures shall mature and the principal shall be due and payable together with
all accrued and unpaid interest thereon on May __, 2025, and shall be issued in
the form of registered Series A Debentures without coupons, as set forth in
Article Four hereof.

<PAGE>


     SECTION 102.  Except as provided in Section 106 herein, the Series A
Debentures shall be issued in certificated form. Principal of and interest (and
to the extent legally enforceable, interest on any overdue principal and on any
overdue instalment of interest) on the Series A Debentures issued in
certificated form will be payable, the transfer of such Series A Debentures will
be registrable and such Series A Debentures will be exchangeable for the Series
A Debentures bearing identical terms and provisions at the office or agency of
the Company in the Borough of Manhattan, The City and State of New York;
PROVIDED, HOWEVER, that payment of interest may be made at the option of the
Company by check mailed to the Person entitled thereto at such address as shall
appear in the Security Register.

     SECTION 103.  Each Series A Debenture will bear interest at the rate of
___% per annum from the original date of issuance until the principal thereof
becomes due and payable, and on any overdue principal and (to the extent that
payment of such interest is enforceable under applicable law) on any overdue
instalment of interest at the same rate per annum, payable monthly on the last
calendar day of each month (each, an "Interest Payment Date"), commencing on
May 31, 1995, to the person in whose name such Series A Debenture or any
predecessor Series A Debenture is registered, at the close of business on the
Business Day next preceding such Interest Payment Date. Any such interest not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holders on such Regular Record Date, and may be paid to the Person in whose name
the Series A Debenture (or one or more Predecessor Securities) is registered at
the close of business on a Special Record Date to be fixed by the Trustee for
the payment of such Defaulted Interest, notice whereof shall be given to the
Holders of the Series A Debentures not less than 10 days prior to such Special
Record Date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Series A Debentures may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture.

     The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months. Interest will accrue from the date of
original issuance to, but not including, the relevant payment date. In the event
that any date on which interest is payable on the Series A Debentures is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date. A "Business Day" means each Monday, Tuesday, Wednesday, Thursday
and Friday which is not a day on which banking institutions in New York and any
other Place of Payment are authorized or obligated by law to close.

     SECTION 104.  The provisions of Section 1006 and 1007 of the Indenture
shall not apply with respect to the Series A Debentures.

     SECTION 105.  The Events of Default set forth in Sections 501(5) and the
Events of Default set forth in Sections 501(6) and 501(7) to the extent such
Events of Default relate to any Restricted Subsidiary shall not apply with
respect to the Series A Debentures.

                                       -2-

     SECTION 106.  The Series A Debentures shall be issuable in the form of one
or more Global Securities. The Depositary for the Series A Debentures shall be
The Depository Trust Company.

     SECTION 107.  The Series A Debentures shall be issuable only in registered
form without coupons in denominations of $25 and any integral multiple thereof.

the Company, as a whole or in part, at any time on or after May_____, 2000 and
prior to Maturity, upon not less than 30 nor more than 60 days' notice, at 100%
of the principal amount redeemed, together with accrued interest to the date
fixed for redemption.


                                  ARTICLE THREE

                      EXTENSION OF INTEREST PAYMENT PERIOD

     SECTION 301. The Company shall have the right, at any time during the term
of the Series A Debentures, from time to time to extend the interest payment
period of such Series A Debentures for up to 60 consecutive months (the
"Extension Period"), at the end of which period the Company shall pay all
interest accrued and unpaid thereon (together with interest thereon at the rate
specified for the Series A Debentures; PROVIDED that, during such Extension
Period, the Company shall not declare or pay any dividend on, or redeem,
purchase, acquire or make a liquidation payment with respect to, any of its
capital stock or make any guarantee payments with respect to the foregoing.
Prior to the termination of any such Extension Period, the Company may further
extend such Extension Period. Any Extension Period together, if extended, with
all such previous and further extensions thereof, (i) shall terminate on an
Interest Payment Date and (ii) shall not exceed 60 consecutive months or extend
beyond the Stated Maturity of the Series A Debentures. Upon the termination of
any Extension Period and upon the payment of all accrued and unpaid interest
then due, the Company may select a new Extension Period, subject to the
foregoing requirements. No interest during an Extension Period, except at the
end thereof, shall be due and payable.

     SECTION 302.  (a)  The Company shall give the Holders of the Series A
Debentures and the Trustee written notice of its selection of such Extension
Period not less than 10 Business Days prior to the earlier of (i) the next
succeeding Interest Payment Date or (ii) the date the Company is required to
give notice to Holders of the Series A Debentures (or, if applicable, to the New
York Stock Exchange or other applicable self-regulatory organization) of the
record or payment date of such interest payment, but in any event not less than
two business days prior to such record date.

                                       -3-

     (b)  The month in which any notice is given pursuant to paragraph (a) of
this Section shall constitute one of the 60 months which comprise the maximum
Extension Period.

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.

     The Company shall have the right, at any time during the term of the
Securities, from time to time to extend the interest payment period of such

Company may further extend such Extension Period. Any such Extension Period
together, if extended, with all such previous and further extensions thereof (i)
shall terminate on an Interest Payment Date and (ii) shall not exceed
60 consecutive months or extend beyond the Stated Maturity of the Security. At
the termination of any such Extension Period and upon the payment of all accrued
and unpaid interest and any additional amounts then due, the Company may select
a new Extension Period.

     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.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

                         (FORM OF REVERSE OF DEBENTURE)

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of May __, 1995 (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and Mellon Bank, N.A., as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), as supplemented by the First Supplemental Indenture, dated as of May
__, 1995 between the Company and the Trustee (the "First Supplemental
Indenture"), and reference is hereby made to the Indenture as supplemented by
the First Supplemental Indenture for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee, the holders of the Senior Indebtedness and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof, limited in aggregate principal amount to $230,000,000.

     The Securities of this series are subject to redemption upon not less than
30 days' notice by mail, at any time on or after __________, 2000, as a whole or
in part, at the election of the Company, at a Redemption Price equal to 100% of
the principal amount, together in the case of any such redemption with accrued
interest to the Redemption Date, but interest installments whose Stated Maturity
is on or prior to such Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, of record at the close of
business on the relevant Record Dates referred to on the face hereof, all as
provided in the Indenture.

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

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture and the First Supplemental Indenture, subordinated and subject in
right of payment to the prior payment in full of all Senior Indebtedness, and
this Security is issued subject to the provisions

                                       -6-
<PAGE>

of the Indenture with respect thereto. Each Holder of this Security, by
accepting the same, (a) agrees to and shall be bound by such provisions,
(b) authorizes and directs the Trustee on his behalf to take such action as may
be necessary or appropriate to acknowledge or effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes. Each Holder hereof, by his acceptance hereof, hereby waives all notice
of the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such Holder upon said
provisions.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Security upon compliance with certain conditions set forth
in the Indenture.

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

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of 66 2/3% in principal amount of the Securities at the
time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

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

     The Securities of this series are issuable only in registered form without
coupons in denominations of $25 and any integral multiple thereof. As provided
in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

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

UNUM ANNOUNCES FIRST QUARTER EARNINGS
PORTLAND, Maine... UNUM Corporation (NYSE:UNM) today announced first quarter
1995 net income of $63.4 million or $0.87 per share, compared with $77.1 million

$955.1 million versus $875.1 million for the same quarter in 1994.

     "This quarter's results reflect unfavorable claims experience in our United

group and individual disability businesses in the United States have shown
improvement over fourth quarter 1994 operating earnings," said James F. Orr III,
chairman and chief executive officer of UNUM Corporation.  "We continue to make
progress on several initiatives we have under way to better address today's risk
environment.  This quarter, annualized premium in our group long term disability
line surpassed $1 billion and we are on track with our strategy to develop new
products for the domestic individual disability market."

     UNUM's Disability Insurance segment reported pretax income of $50.8 million
in first quarter 1995 versus $67.6 million in first quarter 1994.  Premiums for
first quarter 1995 were $451.0 million, compared with $397.7 million in the same
quarter of 1994.
