or representations by, counsel, unless such officer knows, or in the exercise of

waiver or other action provided or permitted by this Indenture to be given, made
or taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 6.01) conclusive in favor of
the Trustee and the Company, if made in the same manner provided in this
Section.

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

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

               The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite aggregate principal amount of Outstanding Securities
of such series on such record date. Nothing in this paragraph shall be construed
to prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite aggregate
principal amount of Outstanding Securities of the relevant series on the date
such action is taken. Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be
given to the Trustee in writing and to each Holder of Securities of the relevant
series in the manner set forth in Sections 1.06 and 1.07.

               The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving and making of (a) any Notice of Default, (b) any declaration of
acceleration referred to in Section 5.02, (c) any request to institute
proceedings referred to in Section 5.07(2) or (d) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite aggregate principal amount of
Outstanding Securities of such series on such record date. Nothing in this
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite aggregate principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date
is set pursuant to this paragraph, the Trustee, at the Company's expense, shall
cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the 


                                       10
   17
Company in writing and to each Holder of Securities of the relevant series in
the manner set forth in Sections 1.06 and 1.07.

               With respect to any record date set pursuant to this Section,
the party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities of the relevant series in the manner
set forth in Section 1.07, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant
to this Section, the party hereto which set such record date shall be deemed to
have initially designated the 180th day after such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

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

SECTION 1.06.  NOTICES TO TRUSTEE AND COMPANY.

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

                             (1) the Trustee by any Holder or by the Company
               shall be sufficient for every purpose hereunder if made, given,
               furnished, or filed in writing to or with the Trustee at Four
               Albany Street, New York, New York 10006, Attention: Corporate
               Trust Department; or

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

               The Company or the Trustee by notice to the other may designate
additional or different addresses for subsequent notices or communications.

SECTION 1.07.  NOTICE TO HOLDERS; WAIVER.

               Any notice or communication given to a Holder of Securities shall
be mailed to such Securityholder at the Securityholder's address as it appears
on the registration books of the Security Registrar and shall be sufficiently
given if so mailed within the time prescribed for the giving of such notice.

               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 



                                       11
   18
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. If a notice or communication is mailed in the manner provided above, it
is duly given, whether or not received by the addressee.

               If the Company mails a notice or communication to the Holders of
Securities of a particular series, it shall mail a copy to the Trustee and each
Security Registrar, co-registrar or Paying Agent, as the case may be, with
respect to such series.

               In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give notice to Holders of
Securities by mail, then such notification as shall be made with the acceptance
of the Trustee shall constitute a sufficient notification for every purpose
hereunder. In any case where notice to Holders of Securities is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder of a Security shall affect the sufficiency of such
notice with respect to other Holders of Securities.

SECTION 1.08.  CONFLICT WITH TRUST INDENTURE ACT.

               If any provision of this Indenture limits, qualifies or conflicts
with a provision of the TIA which is required under the TIA to be a part of and
govern this Indenture, the required provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which 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.

SECTION 1.09.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 1.10.  SUCCESSORS AND ASSIGNS.

               All agreements of the Company in this Indenture and the
Securities shall bind its successors and assigns, whether so expressed or not.
All agreements of the Trustee in this Indenture shall bind its successors and
assigns, whether so expressed or not.

SECTION 1.11.  SEPARABILITY CLAUSE.

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

SECTION 1.12.  BENEFITS OF INDENTURE.

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

SECTION 1.13.  GOVERNING LAW.

               This indenture and the securities shall be governed by and
construed in accordance with the laws of the state of New York, as applied to
contracts made and performed within the state of New York, without regard to
principles of conflicts of law.

SECTION 1.14.  LEGAL HOLIDAYS.

               A "Legal Holiday" is any day other than a Business Day. If any
specified date (including an Interest Payment Date, Redemption Date or Stated
Maturity of any Security, or a date for giving notice) is a Legal Holiday at any
Place of Payment or place for giving notice, then (notwithstanding any other
provision of this Indenture or of the Securities other than a provision in the
Securities of any series which specifically states that such provision shall
apply in lieu of this Section) payment of interest or principal need not be
made at such Place of Payment, or such other action need not be taken, on such
date, but the action shall be taken on the next succeeding day that is not a
Legal Holiday at such Place of Payment with the same force and effect as if made
on the Interest Payment Date or Redemption Date, or at the Stated Maturity or
such other date and to the extent applicable no Original Issue Discount or
interest, if any, shall accrue for the intervening period.

SECTION 2.01.  FORMS GENERALLY.

               The Securities of each series shall be in substantially such form
(including global form) as set forth in this Article or in such other form as
shall be established by delivery to the Trustee of an Officers' Certificate or
in one or more indentures supplemental hereto, in each case with such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have such letters, numbers or other marks of identification and such
legends or endorsements placed thereon as may be required to comply with the
rules of any securities exchange or as may, consistently herewith, be determined
by the Officers executing such Securities as evidenced by their execution of the
Securities. The Officers' Certificate so establishing the form of Security, if
any, of any series shall be delivered to the Trustee at or prior to the delivery
of the Company Order contemplated by Section 3.03 for the authentication and
delivery of such Securities.

               The permanent Securities shall be printed, lithographed or
engraved or produced by any combination of these methods or may be produced in
any other manner, all as determined by the Officers executing such Securities as
evidenced by their execution of such Securities.

which is overdue shall bear interest at the rate of _________% per annum (to the
extent that the payment of such interest shall be legally enforceable), from the

provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be the
_________________ or ________________ (whether or not a Business Day), as the
case may be, next preceding such Interest Payment Date. Any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Regular Record Date and may either be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities of this series not less than 10 days prior to such Special Record

of such interest shall be legally enforceable), from the dates such amounts are
due until they are paid or made available for payment. Interest on any overdue
principal or premium shall be payable on demand. [Any such interest on overdue
principal or premium which is not paid on demand shall bear interest at the rate
of ________% per annum (to the extent that the payment of such interest on
interest shall be legally enforceable), from the date of such demand until the
amount so demanded is paid or made available for payment. Interest on any
overdue interest shall be payable on demand.]]

Payment of the principal of (and premium, if any) and [if applicable, insert --
any such] interest on this Security will be made at the office or agency of the
Company maintained for that purpose in __________________, in such coin or

interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register].

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

Unless the certificate of authentication hereon has been executed by the Trustee
referred to on the reverse hereof by manual signature, this Security shall not

               [If applicable, insert -- The sinking fund for this series
provides for the redemption on ___________ in each year beginning with the year
____________ and ending with the year ________ of [if applicable, insert -- not
less than $ ________ ("mandatory sinking fund") and not more than] $_________

become due].]

               [If the Security is subject to redemption of any kind, insert --
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.]

defeasance at any time of [the entire indebtedness of this Security] [or]
[certain restrictive covenants and Events of Default with respect to this

               [If the Security is convertible into Common Stock of the Company,
insert -- 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 covert the principal
amount of this Security (or any portion hereof which is $1,000 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 fully 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 



                                       17
   24
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 property receivable upon the consolidation, merger or
sale by a holder of the number of shares of Common Stock into which this
Security might have been converted immediately prior to such consolidation,
merger or sale (assuming such holder of Common Stock failed to exercise any
rights of 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 were 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 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 convertible into other securities of the
Company, specify the conversion features.)

               [If the Security is not an Original Issue Discount Security,
insert -- 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.]

               [If the Security is an Original Issue Discount Security, insert
- -- If an Event of Default with respect to Securities of this series shall occur
and be continuing, an amount of principal of the Securities of this series may
be declared due and payable in the manner and with the effect provided in the
Indenture. Such amount shall be equal to -- insert formula for determining the
amount. Upon payment (a) of the amount of principal so declared due and payable
and (b) of interest on any overdue principal, premium and interest (in each case
to the extent that the payment of such interest shall be legally enforceable),
all of the Company's obligations in respect of the payment of the principal of
and 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 more than 50% in aggregate
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 aggregate 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.

               [If the Security is an Original Issue Discount Security, -- In
determining whether the Holders of the requisite aggregate principal amount of
the Outstanding Securities have given any request, demand, authorization,
direction, notice, consent or waiver under the Indenture or whether a quorum is
present at a meeting of Holders of Securities, the principal amount of any
Original Issue Discount Security that shall be deemed to be Outstanding shall be
the amount of the principal thereof that would be due and payable as of the date
of such determination upon the acceleration of the Maturity thereof.]

               As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in aggregate
principal amount of the Securities of this series at the time Outstanding shall
have made written request to the Trustee to institute proceedings in respect of
such Event of Default as Trustee and offered the Trustee reasonable indemnity,
and the Trustee shall not have received from the Holders of a majority in
aggregate principal amount of Securities of this series at the time Outstanding
a direction inconsistent with such request, and shall have failed to institute
any such proceeding, for 90 days after receipt of such notice, request and offer
of indemnity. The foregoing shall not apply to any suit instituted by the Holder
of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

               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 any
premium and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed.

therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the

premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or its
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

shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series. With respect to Securities of

designated in an Officers' Certificate, in accordance with other procedures
specified in a Company Order as contemplated by the third paragraph of Section

or supplemental indenture, the Securities of each series shall be issuable only
in registered form without coupons and only in such denominations as shall be
specified as contemplated by Section 3.01. In the absence of any such specified
denomination with respect to the Securities of any series, the Securities of
such series shall be issuable in denominations of $1,000 and any integral
multiple thereof.

SECTION 3.03.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

               The Securities shall be executed on behalf of the Company by its
Chairman of the Board, one of its Vice Chairmen, its President or one of its
Vice Presidents, or the Treasurer or any Assistant Treasurer, 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 such Company Order shall authenticate and deliver
such Securities; provided, however, that, with respect to Securities of a series
subject to a Periodic Offering, (1) such Company Order may be delivered by the
Company to the Trustee prior to the delivery to the Trustee of such Securities
for authentication and delivery, (2) the Trustee shall authenticate and deliver
Securities of such series for original issue from time to time, in an aggregate
principal amount not exceeding the aggregate principal amount established for
such series, pursuant to a Company Order or pursuant to such procedures
acceptable to the Trustee as may be specified from time to time by a Company
Order, (3) the rate or rates of interest, if any, the Stated Maturity or
Maturities, the original issue date or dates, the redemption provisions, if any,
and any other terms of Securities of such series shall be determined by a
Company Order or pursuant to such procedures and (4) if provided for in such
procedures, such Company Order may authorize authentication and delivery
pursuant to oral or electronic instructions from the Company, or the Company's
duly authorized agent 



                                       25
   32
or agents designated in an Officers' Certificate, which oral instructions shall
be promptly confirmed in writing.

               If the forms or terms of the Securities of the series have been
established in or pursuant to one or more Officers' Certificates as permitted by
Sections 2.01 and 3.01, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be
fully protected in relying upon, an Opinion of Counsel stating:

                     (1) that the form and terms of such Securities have been
      duly authorized by the Company and established in conformity with the
      provisions of this Indenture; and

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

provided, however, that, with respect to Securities of a series subject to a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of
Securities of such series and that the Opinion of Counsel above may state:

                     (x) that the forms of such Securities have been, and the
      terms of such Securities (when established in accordance with such
      procedures as may be specified from time to time in a Company Order all as
      contemplated by and in accordance with a Board Resolution or an Officers'
      Certificate pursuant to Section 3.01, as the case may be) will have been,
      duly authorized by the Company and established in conformity with the
      provisions of this Indenture; and

                     (y) that such Securities when (i) executed by the Company,
      (ii) completed, authenticated and delivered by the Trustee in accordance
      with this Indenture, and (iii) issued and delivered by the Company and
      paid for in the manner and subject to any conditions specified in such
      Opinion of Counsel, will constitute valid and legally binding obligations
      of the Company enforceable in accordance with their terms, subject to
      customary exceptions.

               With respect to Securities of a series subject to a Periodic
Offering, the Trustee may conclusively rely, as to the authorization by the
Company of any of such Securities, the form and terms thereof and the legality,
validity, binding effect and enforceability thereof, upon the Opinion of Counsel
and other documents delivered pursuant to Sections 2.01 and 3.01 and this
Section , as applicable, at or prior to the time of the first authentication of
Securities of such series unless and until it has received written notification
that such opinion or other documents have been superseded or revoked. In
connection with the authentication and delivery of Securities of a series
subject to a Periodic Offering, the Trustee shall be entitled to assume that the
Company's instructions to authenticate and deliver such Securities do not
violate any rules, 



                                       26
   33
regulations or orders of any governmental agency or commission having
jurisdiction over the Company.

               Notwithstanding the provisions of Section 3.01 and of the
preceding paragraph, if all Securities of a series are subject to a Periodic
Offering, it shall not be necessary to deliver the Officers' Certificate
otherwise required pursuant to Section 3.01 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 authentication, upon original issuance of the first
Security of such series to be issued.

               Each Security shall be dated the date of its authentication.

               The Trustee may appoint an Authenticating Agent acceptable to the
Company to authenticate Securities. Unless otherwise provided in the
appointment, an Authenticating Agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent.

               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
duly executed by the Trustee by manual signature of an authorized signatory, and
such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. The Trustee's certificate of authentication shall be in substantially
the form set forth in Section 2.05.

               Notwithstanding the foregoing, if any Security shall have been
duly 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 3.09 together with a written statement
(which need not comply with Section 1.03 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 3.04.  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.

               If temporary Securities of any series are issued, the Company
will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for
that series, without charge to the Holder. Upon surrender for cancellation of
any one or more 



                                       27
   34
temporary Securities of any series, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

SECTION 3.05.  REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

               The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register maintained in such office and in any
other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Securities and of 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 at
the office or agency of the Company designated pursuant to Section 10.02 for
such purpose in a Place of Payment, 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 any authorized denomination or
denominations 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 the same series of any authorized denomination
or denominations, 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 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 3.04, 9.06 or 11.07 not involving any
transfer.

               The Company may but shall not be required (a) to issue, register
the transfer of or exchange Securities of any series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.03 and ending
at the close of business on the day of such mailing, or (b) 



                                       28
   35
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.

               The provisions of Clauses (1), (2), (3) and (4) below shall apply
only to Global Securities:
                             (1) Each Global Security authenticated under this
               Indenture shall be registered in the name of the Depositary
               designated for such Global Security or a nominee thereof and
               delivered to such Depositary or a nominee thereof or custodian
               therefor, and each such Global Security shall constitute a single
               Security for all purposes of this Indenture.

                             (2) Notwithstanding any other provision in this
               Indenture, no Global Security may be exchanged in whole or in
               part for Securities registered, and no transfer of a Global
               Security in whole or in part may be registered, in the name of
               any Person other than the Depositary for such Global Security or
               a nominee thereof unless (a) such Depositary (i) has notified the
               Company that it is unwilling or unable to continue as Depositary
               for such Global Security or (ii) has ceased to be a clearing
               agency registered under the Exchange Act, (b) the Company
               executes and delivers to the Trustee a Company Order that such
               Global Security shall be so exchangeable, (c) there shall have
               occurred and be continuing an Event of Default with respect to
               such Global Security or (d) there shall exist such circumstances,
               if any, in addition to or in lieu of the foregoing as have been
               specified for this purpose as contemplated by Section 3.01.

                             (3) Subject to Clause (2) above, any exchange of a
               Global Security for other Securities may be made in whole or in
               part, and all Securities issued in exchange for a Global Security
               or any portion thereof shall be registered in such names as the
               Depositary for such Global Security shall direct.

                             (4) Every Security authenticated and delivered upon
               registration of transfer of, or in exchange for or in lieu of, a
               Global Security or any portion thereof, whether pursuant to this
               Section , Section 3.04, 3.06, 9.06, or 11.07 or otherwise, shall
               be authenticated and delivered in the form of, and shall be, a
               Global Security, unless such Security is registered in the name
               of a Person other than the Depositary for such Global Security or
               a nominee thereof.

SECTION 3.06.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

               If (a) any mutilated Security is surrendered to the Trustee, or
(b) the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company and the Trustee such security or indemnity as may be required by them to
save each 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 written request the Trustee shall
authenticate and deliver, in exchange for any such mutilated Security or in lieu
of any such destroyed, lost or stolen Security, a new Security of the same
series and of like tenor and principal amount, bearing a number not
contemporaneously Outstanding.



                                       29
   36
               In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

               Upon the issuance of any new Securities 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 mutilated, destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the
mutilated, destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and any such new Security shall be entitled to all benefits of this
Indenture equally and proportionately with any and all other Securities of that
issue.

               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 3.07.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

               Unless otherwise provided as contemplated by Section 3.01 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 and the date of the proposed payment, and at
      the same time the Company shall deposit with the Trustee an amount of
      money equal to the aggregate amount proposed to be paid in respect of such
      Defaulted Interest or shall make arrangements satisfactory to the Trustee
      for such deposit prior to the date of the proposed payment, such money
      when deposited to be held in trust for the benefit of the Persons entitled
      to such Defaulted Interest as in this Clause provided. Thereupon the
      Trustee shall fix a Special Record Date for the payment of such Defaulted
      Interest which shall be not more than 15 days and not less than 10 days
      prior to the date of the proposed payment and not less than 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 



                                       30
   37
      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 at his or her 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 (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 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 14.02, in the case of any
Security (or any part thereof) 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 Stated Maturity or by declaration of acceleration prior to
such Interest Payment Dated), 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 any 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 or in Section 14.02, in the case of any Security (or any part thereof)
which is converted, interest whose Stated Maturity is after the date of
conversion of such Security or such part thereof shall not be payable.

SECTION 3.08.  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 (except
as otherwise specified as contemplated by Section 3.01 and subject to Section
3.05 and Section 3.07) 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.

               No holder of any beneficial interest in any Global Security held
on its behalf by a Depositary (or its nominee) shall have any rights under this
Indenture with respect to such Global Security or any Security represented
thereby, and such Depositary may be treated by the Company, the Trustee, and any
agent of the Company or the Trustee as the owner of such Global Security or any
Security represented thereby for all purposes whatsoever. 



                                       31
   38
Notwithstanding the foregoing, with respect to any Global Security, nothing
herein shall prevent the Company, the Trustee, or any agent of the Company or
the Trustee, from giving effect to any written certification, proxy or other
authorization furnished by a Depositary or impair, as between a Depositary and
such holders of beneficial interest, the operation of customary practices
governing the exercise of the rights of the Depositary (or its nominees) as
Holder of any Security.

SECTION 3.09.  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 all Registered Securities so delivered shall be promptly canceled 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 (including Securities received by the Company
in exchange or payment for other Securities of the Company) 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 to the Trustee shall be
promptly canceled by the Trustee. The Company may not reissue, or issue new
Securities to replace, Securities it has paid for or delivered to the Trustee
for cancellation. No Securities shall be authenticated in lieu of or in exchange
for any Securities canceled as provided in this Section , except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall
be destroyed by the Trustee and evidence of their destruction delivered to the
Company unless the Company directs by Company Order that the Trustee deliver
canceled Securities to the Company.

SECTION 3.10.  COMPUTATION OF INTEREST.

               Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of any series shall be
computed on the basis of a 360-day year of twelve 30-day months.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

SECTION 4.01.  SATISFACTION AND DISCHARGE OF INDENTURE.

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

               (1)    either

                      (a) all Securities theretofore authenticated and delivered
        (other than (i) Securities which have been destroyed, lost or stolen and
        which have been replaced or paid as provided in Section 3.06 and (ii)
        Securities for whose payment money has theretofore been deposited in
        trust or segregated and held in trust by the Company and thereafter
        repaid to the Company or discharged from such trust, as provided in
        Section 10.03) have been delivered to the Trustee for cancellation; or




                                       32
   39
                      (b) all such Securities not theretofore delivered to the
         Trustee for cancellation

                             (i)    have become due and payable, or

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

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

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

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

               (3) the Company has delivered to the Trustee an 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 have been complied with.

               Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 6.07, the
obligations of the Trustee to any Authenticating Agent under Section 6.14 and,
if money shall have been deposited with the Trustee pursuant to subclause (b) of
Clause (1) of this Section , the obligations of the Trustee under Section 4.02
and the last paragraph of Section 10.03 shall survive.

SECTION 4.02.  APPLICATION OF TRUST MONEY.

               Subject to the provisions of the last paragraph of Section 10.03,
all money deposited with the Trustee pursuant to Section 4.01 shall be held in
trust and applied by it, in accordance with the provisions of the Securities and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                  ARTICLE FIVE

                                    REMEDIES

SECTION 5.01.  EVENTS OF DEFAULT.

               "Event of Default," wherever used herein with respect to
Securities of any series, means any one of the following events (whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or 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):



                                       33
   40
                     (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;

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

                     (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 other than that
      series), and continuance of such Default or breach for a period of 90 days
      after there has been given, by registered or certified mail, to the
      Company by the Trustee or to the Company and the Trustee by the Holders of

SECTION 5.02.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

               If an Event of Default with respect to Securities of any series
at the time Outstanding (other than an Event of Default specified in Section
5.01(5) or (6)) occurs 



                                       34
   41
and is continuing, the Trustee by notice to the Company, or the Holders of at
least 25% in aggregate principal amount of the Outstanding Securities of that
series by notice to the Company and the Trustee, may declare the principal
amount of (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) all the Securities of that series to be
immediately due and payable. Upon such a declaration, such principal (or portion
thereof) shall be due and payable immediately. If an Event of Default specified
in Section 5.01(5) or (6) occurs and is continuing, the principal amount (or
portion thereof) of all the Securities of that series shall become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Securityholders.

               At any time after such a declaration of acceleration with respect
to Outstanding 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 aggregate
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 any
                      interest thereon at the rate or rates prescribed therefor
                      in such Securities,

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

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

                             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 5.13.

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

SECTION 5.03.  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,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal and any premium and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses, disbursements and
advances of the Trustee, its agents and counsel.

               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 right, 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 5.04.  TRUSTEE MAY FILE PROOFS OF CLAIM.

               In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Securities, or the property of the Company or of such other obligor or their
creditors, the Trustee 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 6.07.

               No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 5.05.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

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

SECTION 5.06.  APPLICATION OF MONEY COLLECTED.

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

               First: To the payment of all amounts due the Trustee under
Section 6.07; and

               Second:To the payment of the amounts than due and unpaid for

such Securities for principal, and any premium and interest, respectively.

SECTION 5.07.  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 aggregate
               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 



                                       37
   44
               majority in aggregate principal amount of the Outstanding
               Securities of that series;

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

SECTION 5.08.  RIGHTS OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND INTEREST.

               Notwithstanding any other provision of this Indenture, the right,
which is absolute and unconditional, of any Holder of any Security to receive
payment of the principal of and (subject to Section 3.07) interest on such
Security on the Stated Maturity or Maturities expressed in such Security (or, in
the case of redemption, on the Redemption Date) held by such Holder, on or after
the respective due dates expressed in the Securities or any Redemption Date, or
to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected adversely without the
consent of each such Holder.

SECTION 5.09.  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

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

payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 3.06, no right or remedy herein conferred upon or reserved to the
Trustee or 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 5.11.  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 5.12.  CONTROL BY HOLDERS.

               The Holders of a majority in aggregate 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.

SECTION 5.13.  WAIVER OF PAST DEFAULTS.

               The Holders of not less than a majority in aggregate principal
amount of the Outstanding Securities of all series that would be affected by
such a default (voting as one class) may, on behalf of the Holders of all the
Securities of such series, waive any past Default hereunder with respect to such
series and its consequences, except a Default:

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

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

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

SECTION 5.14.  UNDERTAKING FOR COSTS.

               In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant (other than the Trustee) in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 5.14 does not apply to a suit by the Trustee, a
suit by a Holder pursuant to Section 5.07 or a suit by Holders of more than l0%
in aggregate principal amount of the Outstanding Securities of any series, or to
any suit instituted by any Holder of any Security for the enforcement of the
payment of the principal of or interest on any Security on or after the Stated
Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

of this Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties

relating to the conduct or affecting the liability of or affording protection to
the Trustee shall be subject to the provisions of this Section .

responsible officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of Securities of such series;

               The Company agrees:

               (1) to pay to the Trustee from time to time reasonable

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.

applicable requirements of Section 6.11.

               The Trustee may resign at any time with respect to the Securities

not have been delivered to the Trustee 



                                       42
   49
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee with respect to the Securities of such series.

               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 aggregate
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and to the Company.

               If at any time:

                             (1) the Trustee shall fail to comply with Section
               6.08 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 6.09 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, (a) the Company by a Company Order may remove the
Trustee with respect to all Securities, or (b) subject to Section 5.14, 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.

               If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Company
Order, 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 6.11. 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 aggregate 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 6.11, 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 6.11, 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.

SECTION 6.11.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

               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

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

               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 the first or second preceding paragraph, as the case may be.

time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

               Any corporation into which the Trustee may be merger 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 6.13.  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 6.14.  APPOINTMENT OF AUTHENTICATING AGENT.

               At any time when any of the Securities remain Outstanding, the
Trustee, with the concurrence of the Company, 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 original issue, and upon exchange, registration of transfer
or partial redemption thereof or pursuant to Section 3.06, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the 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, State or District of Columbia 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 anytime 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 .

   52
               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 give notice of such
appointment in the manner provided in Section 1.07 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. 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 6.07.

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

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

                                    COVENANTS

SECTION 10.01.  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 any
premium and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture. In the absence of contrary
provisions with respect to the Securities of any series, interest on the
Securities of any series may, at the option of the Company, be paid by check
mailed to the address of the Person entitled thereto as it appears on the
Security Register. An installment of principal of or interest on the Securities
shall be considered paid on the date it is due if the Trustee or a Paying Agent
(other than the Company or an Affiliate of the Company) holds on that date funds
designated for and sufficient to pay such installment.



                                       51
   58
SECTION 10.02.  MAINTENANCE OF OFFICE OR AGENCY.

               As long as any of the Securities of a series remain Outstanding,
the Company will maintain in each Place of Payment for such series an office or
agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency in respect of any
series of Securities or shall fail to furnish the Trustee with the address
thereof, such presentations and surrenders of Securities of that series may be
made and notices and demands may be made or served at the address of the Trustee
set forth in Section 1.06, and the Company hereby appoints the Trustee as its
agent to receive all such 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 accordance with the requirements set forth above 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.

SECTION 10.03.  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 or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

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

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




                                       52
   59
               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 or any premium
or interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company 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 each Place of
Payment, 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 10.04.  COMPLIANCE CERTIFICATE.

               The Company shall 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, one of the signatures of which shall be that of the
Company's principal executive, financial or accounting officer, 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 this Indenture (without regard to any period of grace or requirement of
notice provided hereunder) 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 10.05.  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 10.06.  PAYMENT OF TAXES AND OTHER CLAIMS.

               The Company will or will cause a Restricted Subsidiary to pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Restricted Subsidiary or upon the income,
profits or property of the Company or any Restricted Subsidiary, and (b) all
lawful claims for labor, materials and supplies which, if 



                                       53
   60
unpaid, might by law become a lien upon the property of the Company or any
Restricted 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 or if the Company shall determine that the
failure to pay would not have a material adverse effect on the Company and its
subsidiaries taken as a whole.

SECTION 10.07.  LIMITATIONS ON LIENS.

               The Company shall not, and shall not permit any Restricted
Subsidiary to, incur, issue, assume or guarantee debt secured by any Lien upon
any Principal Property, without making, or causing such Restricted Subsidiary to
make, effective provision whereby the Securities then Outstanding and having the
benefit of this Section shall be secured by the Lien equally and ratably with
such debt for so long as such debt shall be so secured, except that the
foregoing shall not prevent the Company or any Restricted Subsidiary from
creating, assuming or suffering to exist any Lien existing at the date of this
Indenture or Liens of the following character:

                             (1) any Lien existing on any Principal Property
               owned or leased by a corporation at the time it becomes a
               Restricted Subsidiary;

                             (2) any Lien existing on Principal Property at the
               time of the acquisition thereof by the Company or a Restricted
               Subsidiary;

                             (3) any Lien to secure any debt incurred prior to,

               Principal Property for the purpose of financing all or any part
               of the purchase price thereof and any Lien to the extent that it
               secures debt which is in excess of such purchase price and for
               the payment of which recourse may be had only against such
               Principal Property;

                             (4) any Lien to secure any debt incurred prior to,
               at the time of, or within 12 months after the completion of the
               construction and commencement of commercial operation,
               alteration, repair or improvement of Principal Property for the
               purpose of financing all or any part of the cost thereof and any
               Lien to the extent that it secures debt which is in excess of
               such cost and for the payment of which recourse may be had only
               against such Principal Property;

                             (5) any Lien in favor of the Company or any
               Affiliate;

               America or any State thereof or any other country, or any agency,
               instrumentality or political subdivision or any of the foregoing,
               to secure partial, progress, advance or other payments or
               performance pursuant to the provisions of any contract or
               statute, or to secure any indebtedness incurred for the purpose
               of financing all or any part of the purchase price or the cost of
               constructing or improving the property subject to such Lien;

                             (7) Liens imposed by law, such as mechanics',
               workmen's, repairmen's, materialmen's, carriers', warehousemen's,
               vendors' or other similar Liens arising in the ordinary course of
               business, or 



                                       54
   61
               governmental (federal, state or municipal) Liens arising out of
               contracts for the sale of products or services by the Company or
               any Restricted Subsidiary, or deposits or pledges to obtain the
               release of any of the foregoing;

               of cash or obligations of the United States of America to secure
               surety, appeal or customs bonds to which the Company or any
               Restricted Subsidiary is a party, or deposits in litigation or
               other proceedings such as, but not limited to, interpleader

               in the ordinary course of the business of the Company or such
               Restricted Subsidiary and which do not, in the opinion of the
               Company, materially detract from the value of such properties;

                             (12) Liens securing obligations issued by a State,

               acquisition or construction of property, and on which the
               interest is not, in the opinion of tax counsel or in accordance
               with a ruling issued by the Internal Revenue Service, includible
               in gross income of the holder by reason of Section 103(a) of the
               Internal Revenue Code (or any successor to such provision) as in
               effect at the time of the issuance of such obligations;



                                       55
   62
                             (13) Liens on or with respect to coal, gas,
               hydrocarbon or mineral properties not fully developed securing

               successive extensions, renewals or replacements), in whole or in
               part, of any Lien referred to in clauses (1) through (15) above,
               so long as the principal amount of the debt secured thereby does
               not exceed the principal amount of debt so secured at the time of
               the extension, renewal or replacement (except that, where an
               additional principal amount of debt is incurred to provide funds
               for the completion of a specific project, the additional
               principal amount, and any related financing costs, may be secured
               by the Lien as well) and the Lien is limited to the same property
               subject to the Lien so extended, renewed or replaced (plus
               improvements on the property).

               Notwithstanding the foregoing provisions of this Section 10.07,
the Company and any one or more Restricted Subsidiaries may issue, assume or
guarantee debt secured by a Lien which would otherwise be subject to the
foregoing restrictions if at the time it does so (the "Incurrence Time") the
aggregate amount of such debt plus all other debt of the Company and its
Restricted Subsidiaries secured by a Lien which would otherwise be subject to
the foregoing restrictions (not including debt permitted to be secured under the
foregoing restrictions), plus the aggregate Attributable Debt (determined as of
the Incurrence Time) of Sale and Leaseback Transactions (other than Sale and
Leaseback Transactions permitted by Section 10.08) entered into after the date
hereof and in existence at the Incurrence Time (less the aggregate amount of
proceeds of such Sale and Leaseback Transactions which shall have been applied
in accordance with Section 10.08) does not exceed 15% of Consolidated Net
Tangible Assets.

SECTION 10.08.  RESTRICTIONS ON SALE AND LEASEBACK TRANSACTIONS.

               The Company will not itself, and it will not permit any
Restricted Subsidiary to, enter into any arrangement with any bank, insurance
company or other lender or investor (not including the Company or any Affiliate)
or to which any such lender or investor is a party, providing for the leasing by
the Company or a Restricted Subsidiary for a period, including renewals, in
excess of three years of any Principal Property which has been or is to be sold
or transferred by the Company or any Restricted Subsidiary to such lender or
investor or to any Person to whom funds have been or are to be advanced by such
lender or investor on the security of such Principal Property (herein referred
to as a "Sale and Leaseback Transaction") unless either:

                             (1) the Company or such Restricted Subsidiary
               would, at the time of entering into such arrangement, be
               entitled, without equally and ratably securing the Securities of
               each series then Outstanding, to 



                                       56
   63
               incur, issue, assume or guarantee debt secured by a Lien on such
               property, pursuant to paragraphs (1) to (16), inclusive, of
               Section 10.07; or

                             (2) the Company, within 180 days after the sale or
               transfer shall have been made by the Company or by a Restricted
               Subsidiary, applies an amount equal to the greater of (a) the net
               proceeds of the sale of the Principal Property sold and leased
               back pursuant to such arrangement or (b) the fair market value of
               the Principal Property so sold and leased back at the time of
               entering into such arrangement (as determined by: the Chairman or
               a Vice Chairman of the Board of the Company, its President or a
               Vice President, and by its Treasurer, an Assistant Treasurer, its
               Secretary or an Assistant Secretary) to the retirement of Funded
               Debt of the Company; provided, that the amount to be applied to
               the retirement of Funded Debt of the Company shall be reduced by
               (i) the principal amount of any Securities delivered within 120
               days after such sale to the Trustee for retirement and
               cancellation, and (ii) the principal amount of Funded Debt, other
               than Securities, voluntarily retired by the Company within 120
               days after such sale.

               Notwithstanding the foregoing, the Company and its Restricted
Subsidiaries, or any of them, may enter into a Sale and Leaseback Transaction
which would otherwise be prohibited by this Section 10.08, provided, that at the
time of such transaction, after giving effect thereto, the sum of (i) the
aggregate amount of the Attributable Debt in respect of all Sale and Leaseback
Transactions existing at such time which could not have been entered into except
for the provisions of this paragraph plus (ii) the aggregate amount of
Outstanding debt secured by liens in reliance on the last paragraph of Section
10.07 does not at such time exceed 15% of the Consolidated Net Tangible Assets
of the Company.

               A Sale and Leaseback Transaction shall not be deemed to result in
the creation of a Lien.

SECTION 10.09.  WAIVER OF COVENANTS.

               The Company may omit in any particular instance to comply with
any covenant, term or condition with respect to the Securities of any series if
before or after the time for such compliance the Holders of at least a majority
in aggregate principal amount of the Outstanding Securities of all series that
would be affected by such a waiver (voting as one class) shall, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or 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 covenant or condition shall
remain in full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

SECTION 11.01.  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 3.01 for such Securities) in
accordance with this Article.



                                       57
   64
SECTION 11.02.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

               The election of the Company to redeem any Securities shall be
evidenced by a Company Order. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 45
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

SECTION 11.03.  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

               If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), 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 a portion of the principal amount of any Security of such series,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), 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 and specified tenor not
previously called for redemption in accordance with the preceding sentence.

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

               The provisions of the two preceding paragraphs shall not apply
with respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

               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 11.04.  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 the Holder's address
appearing in the Security Register.




                                       58
   65
               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
consisting of more than a single Security are to be redeemed, the identification
(and, in the case of partial redemption of any such Securities, the principal
amounts) of the particular Securities to be redeemed and, if less than all the
Outstanding Securities of any series consisting of a single Security are to be
redeemed, the principal amount of the particular Security 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 each such Security is to be
surrendered for payment of the Redemption Price, and

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

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

SECTION 11.05.  DEPOSIT OF REDEMPTION PRICE.

               On or 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 10.03) an
amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

SECTION 11.06.  SECURITIES PAYABLE ON REDEMPTION DATE.

               Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest to the Redemption Date; provided, however, that, unless
otherwise specified as contemplated by Section 3.01, installments of interest
whose Stated Maturity is on or prior to the Redemption Date will 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 3.07.

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



                                       59
   66
SECTION 11.07.  SECURITIES REDEEMED IN PART.

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

                                 ARTICLE TWELVE

                                  SINKING FUNDS

SECTION 12.01.  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 3.01 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 12.02. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of the Securities of such series.

SECTION 12.02.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

               The Company (a) may deliver Outstanding Securities of a series
with the same issue date, interest rate and Stated Maturity (other than any
previously called for redemption), and (b) may apply as a credit Securities of a
series with the same issue date, interest rate and Stated Maturity 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 mandatory sinking fund payment with respect to the
Securities of such series with the same issue date, interest rate and Stated
Maturity; provided that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 12.03.  REDEMPTION OF SECURITIES FOR SINKING FUND.

               Not less than 35 days (or such shorter period as shall be
acceptable to the Trustee) prior to each sinking fund payment date for any
series of Securities, the Company 



                                       60
   67
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 12.02 and will also
deliver to the Trustee any Securities to be so delivered. Not less than 30 days
before each such sinking fund payment date the Trustee shall select the
Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 11.03 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 11.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
11.06 and 11.07.

                                ARTICLE THIRTEEN

SECTION 13.01. COMPANY'S RIGHT WITH RESPECT TO DEFEASANCE OR COVENANT
DEFEASANCE.

               The Company will have the right, at any time, to have Section
13.02 or Section 13.03 applied to any Securities or any series of Securities, as
the case may be (other than Securities of a series designated pursuant to
Section 3.01 as not being defeasible pursuant to Section 13.02 or 13.03), upon
compliance with the conditions set forth below in this Article. Any such request
shall be evidenced by a Company Order or in another manner specified as
contemplated by Section 3.01 for such Securities.

SECTION 13.02.  DEFEASANCE AND DISCHARGE.

               Upon the Company's exercise of its right to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 13.04 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by such
Securities and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (a) the rights of Holders of such Securities to
receive, solely from the trust fund described in Section 13.04 and as more fully
set forth in such Section , (i) payments in respect of the principal of and any
premium and interest on the Outstanding Securities on the Stated Maturity of
such principal or installment of principal of and any premium or interest and
(ii) the benefit of any mandatory sinking fund payments applicable to the
Securities on the day on which such payments are due and payable in accordance
with the terms of this Indenture and the Securities, (b) the Company's
obligations with respect to such Securities under Sections 3.04, 3.05, 3.06,
10.02 and 10.03, (c) the rights, powers, trusts, duties and immunities of the
Trustee hereunder, and (d) this Article. Subject to compliance with this
Article, the Company may exercise its option to have this Section applied to any
Securities notwithstanding the prior exercise of its option to have Section
13.03 applied to such securities.



                                       61
   68
SECTION 13.03.  COVENANT DEFEASANCE.

               Upon the Company's exercise of its right to have this Section
applied to any Securities or any series of Securities, as the case may be, (a)
the Company shall be released from its obligations under Section 8.01(3),
Sections 10.06 through 10.08, inclusive, and any covenants provided pursuant to
Section 3.01(21), 9.01(2) or 9.01(7) for the benefit of the Holders of such
Securities and (b) the occurrence of any event specified in Sections 5.01(4)
(with respect to any of Section 8.01(3), Sections 10.06 through 10.08,
inclusive, and any such covenants provided pursuant to Section 3.01(21), 9.01(2)
or 9.01(7)), 5.01(5) and 5.01(6) shall be deemed not to be or result in an Event
of Default, in each case with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 13.04 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Section 5.01(4)), whether directly or indirectly by
reason of any reference elsewhere herein to any such Section or by reason of any
reference in any such Section to any other provision herein or in any other
document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

SECTION 13.04.  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

               The following shall be the conditions to the application of
Section 13.02 or Section 13.03 to any Securities or any series of Securities, as
the case may be:

               (1) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfied the requirements
contemplated by Section 6.09 and agrees to comply with the provisions of this
Article applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefits of the Holders of such Securities, (a) money in an amount, or
(b) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(c) a combination thereof, in each case 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 and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of
this Indenture and such Securities. As used herein, "U.S. Government Obligation"
means (x) any security which is (i) a direct obligation of the United States of
America for the payment of which the full faith and credit of the United States
of America is pledged or (ii) an obligation of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America, which, in either case (i) or (ii),
is not callable or redeemable at the option of the issuer thereof, and (y) any
depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation
which is specified in Clause (x) above and held by such bank for the account of
the holder of such depositary receipt, or with respect to any specific payment
of principal of or interest on any U.S. Government Obligation which is so
specified and held, provided that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of
such depositary receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal or interest
evidenced by such depositary receipt.



                                       62
   69
               (2) In the event of an election to have Section 13.02 apply to
any Securities or any series of Securities, as the case may be, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (a) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling or (b) since the date of this instrument, there has been a
change in the applicable Federal income tax law, in either case (a) or (b) to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Securities will not recognize gain or loss for Federal income tax
purposes as a result of the deposit, Defeasance and discharge to be effected
with respect to such Securities and will be subject to Federal income tax on the
same amount in the same manner and at the same times as would be the case if
such deposit, Defeasance and discharge were not to occur.

               (3) In the event of an election to have Section 13.03 apply to
any Securities or any series of Securities, as the case may be, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Securities will not recognize gain or loss for Federal income
tax purposes as a result of the deposit and Covenant Defeasance to be effected
with respect to such Securities and will be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if
such deposit and Covenant Defeasance were not to occur.

               (4) Such provision would not cause any Outstanding Securities if
then listed on any securities exchange, to be delisted as a result of such
deposit.

               (5) No event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or,
with regard to any such event specified in Sections 5.01(5) and (6), at any time
on or prior to the 90th day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 90th day).

               (6) Such Defeasance or Covenant Defeasance shall not cause the
Trustee to have a conflicting interest within the meaning of the Trust Indenture
Act (assuming all Securities are in default within the meaning of such Act).

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

               (8) Such Defeasance or Covenant Defeasance shall not result in
the trust arising from such deposit constituting an investment company within
the meaning of the Investment Company Act unless such trust shall be registered
under such Act or exempt from registration thereunder.

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

SECTION 13.05.  DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
        TRUST; MISCELLANEOUS PROVISIONS.

               Subject to the provisions of the last paragraph of Section 10.03,
all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee or other qualifying trustee (solely for purposes of
this Section and Section 13.06, the Trustee and 



                                       63
   70
any such other trustee are referred to collectively as the "Trustee") pursuant
to Section 13.04 in respect of any Securities shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held
in trust need not be segregated from other funds except to the extent required
by law.

               The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 13.04 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of Outstanding Securities.

               Anything in this Article to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 13.04 with respect to any Securities which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect the
Defeasance or Covenant Defeasance, as the case may be, with respect to such
Securities.

SECTION 13.06.  REINSTATEMENT.

               If the Trustee or the Paying Agent is unable to apply any money
in accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 13.02 or 13.03 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 13.05 with respect to such
Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Company shall be
subrogated to the rights (if any) of the Holders of such Securities to receive
such payment from the money so held in trust.

                                ARTICLE FOURTEEN

                            CONVERSION OF SECURITIES

SECTION 14.01.  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
3.01 for the Securities of such series.

SECTION 14.02.  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 



                                       64
   71
maintained for that purpose pursuant to Section 10.02, accompanied by a duly
executed conversion notice to the Company substantially in the form set forth in
Section 2.06 stating that the Holder elects to convert such Security or a
specified portion thereof. Such notice shall also state, if different from the
name and address of such Holder, the name or names (with address) 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 (in whole or
in part) 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 any 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 3.07 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 3.03, 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 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
3.07, no payment or adjustment shall be made upon any conversion on account of
any interest accrued on the Securities (or any part thereof) 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.




                                       65
   72
SECTION 14.03.  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 14.03, 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 portion 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
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. For purposes of this Section , "trading
day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday other than
any day on which the Common Stock is not traded on the New York Stock Exchange,
or if the Common Stock is not traded on the new York Stock Exchange, on the
principal exchange or market on which the Common Stock is traded or quoted.

SECTION 14.04.  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, reclassifications, 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 10.02 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 14.05.  NOTICE OF CERTAIN CORPORATE ACTIONS.

               In case:

               (1) 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

               (2) 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

               (3) 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

               (4) 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
Security Register, at least 20 days (or 10 days in any case specified in Clause
(1) or (2) 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 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 14.06.  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 14.07.  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.



                                       67
   74
SECTION 14.08.  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 full paid and nonassessable.

SECTION 14.09.  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 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 14.09. Anything in this Section
14.09 to the contrary notwithstanding, the provisions of this Section 14.09
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.

SECTION 14.10.  DUTIES OF TRUSTEE REGARDING CONVERSION.

               Neither the Trustee nor any conversion agent shall at any time be
under any duty or responsibility to any Holder of Securities of any series that
is convertible into Common Stock of the Company to determine whether any facts
exist which may require any adjustment of the conversion price, or with respect
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 or property, which may at any time be issued or
delivered upon the conversion of any Securities and neither the Trustee nor any
conversion agent makes any representation with respect thereto. Subject to the
provisions of Section 6.01, 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.

SECTION 14.11.  REPAYMENT OF CERTAIN FUNDS UPON CONVERSION.

               Any funds which at any time shall have been deposited by the
Company or on its behalf with the Trustee or any other payment agent for the
purpose of paying the principal of, and premium, if any, and interest, if any,
on any of the Securities (including funds deposited for the sinking fund
referred to in Article Twelve 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 executed and
delivered this Indenture as of the day and year first above written.
