          (ii) Securities for whose payment or redemption money or evidences of
     indebtedness in the necessary amount has been theretofore deposited with
     the Trustee or any Paying Agent (other than the Company) in trust or set
     aside and segregated in trust by the Company (if the Company shall act as
     its own Paying Agent) for the Holders of such Securities; provided,
     however, that, if such Securities are to be redeemed, notice of such
     redemption has been duly given pursuant to this Indenture or provision
     therefor satisfactory to the Trustee has been made; and

          (iii) Securities which have been paid pursuant to Section 306 or in
     exchange for or in lieu of which other Securities have been authenticated
     and delivered pursuant to this Indenture, other than any such Securities in
     respect of which there shall have been presented to the Trustee proof
     satisfactory to it that such Securities are held by a bona fide purchaser
     in whose hands such Securities are valid obligations of the Company;

provided, however, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, Securities owned
by the Company or any other obligor upon the Securities or any Affiliate of the
Company or of such other obligor shall be disregarded and deemed not to be
Outstanding, except that, in determining whether the Trustee shall be protected
in relying upon any such request, demand, authorization, direction, notice,
consent or waiver, only Securities which the Trustee knows to be so owned shall
be so disregarded. Securities so owned which have been pledged in good faith may
be regarded as Outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Securities and that
the pledgee is not the Company or any other obligor upon the Securities or any
Affiliate of the Company or of such other obligor. In case of a dispute as to
such right, any decision by the Trustee shall be full protection to the Trustee.
Upon request of the Trustee, the Company shall furnish to the Trustee promptly
an Officers' Certificate listing and identifying all Securities, if any, known
by the Company to be owned or held by or for the account of any of the
above-described Persons; and, subject to Section 601, the Trustee shall be
entitled to accept such Officers' Certificate as conclusive evidence of the
facts therein set forth and of the fact that all Securities not listed therein
are Outstanding for the purposes of any such determination.

provided for in this Indenture relating to the proposed action have been

     Every certificate or opinion with respect to compliance with a condition or

     has read such covenant or condition and the definitions herein relating

only one document, but one such Person may certify or give an opinion with
respect to some matters and one or more other such Persons as to other matters,
and any such Person may certify or give an opinion as to such matters in one or
several documents.

     Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters is erroneous. Any certificate of counsel or Opinion
of Counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 104. Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by 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 601) conclusive in favor of the Trustee and the Company,
if made in the manner provided in this Section 104.

     (b) The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may be proved in accordance
with such reasonable rules and regulations as may be prescribed by the Trustee
or in any reasonable manner which the Trustee deems sufficient.

     (c) The ownership of Securities shall be proved by the Security Register.

     (d) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to a Board Resolution, fix in advance a record
date for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or


<PAGE>
                                      -10-


other Act, but the Company shall have no obligation to do so. Notwithstanding
Trust Indenture Act Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities shall be computed as of such record date; provided, however, that no
such authorization, agreement or consent by such Holders on such record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than eleven months after the record date.

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

SECTION 105. Notices, Etc., to Trustee and Company.

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

          (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 its Corporate Trust Office, Attention: [ ]; 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, to the attention of the
     general counsel of the Company.

SECTION 106. Notice to Holders; Waiver.

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


<PAGE>
                                      -11-


date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

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

SECTION 107. Conflict with Trust Indenture Act.

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

SECTION 108. Effect of Headings and Table of Contents.

     The article and section headings herein and the table of contents are for
convenience only and shall not affect the construction hereof.

SECTION 109. Successors and Assigns.

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

SECTION 110. 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 111. 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, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

SECTION 112. GOVERNING LAW.

     THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

SECTION 113. Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date or at the Stated
Maturity; provided that no interest shall accrue on any amount payable on or at
such date for the period from and after such Interest Payment Date, Redemption
Date or Stated Maturity, as the case may be, to such next succeeding Business
Day.

                                   ARTICLE II

each case with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture and any indenture

identification and such legends or endorsements placed thereon as may be

Order contemplated by Section 303 for the authentication and delivery of such

SECTION 203. Securities Issuable in the Form of a Global Security.

     (a) If the Company shall establish pursuant to Sections 201 and 301 that
the Securities of a particular series are to be issued in whole or in part in
the form of one or more Global Securities, then the Company shall execute, and
the Trustee shall, in accordance with Section 303 and the Company Order
delivered to the Trustee thereunder, authenticate and deliver, such Global
Security or Securities, which:

          (i) shall represent, and shall be denominated in an amount equal to
     the aggregate principal amount of, the Outstanding Securities of such
     series to be represented by such Global Security or Securities;

          (ii) shall be registered in the name of the Depositary for such Global
     Security or Securities or its nominee;

          INDIVIDUAL SECURITIES REPRESENTED HEREBY, THIS GLOBAL SECURITY MAY NOT
          BE TRANSFERRED EXCEPT AS A WHOLE (I) BY THE DEPOSITARY TO A NOMINEE OF
          THE DEPOSITARY OR (II) BY A NOMINEE OF THE DEPOSITARY OR THE
          DEPOSITARY TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR
          DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
          REPRESENTATIVE OF THE DEPOSITORY

                                      -14-


          TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK) TO THE ISSUER OR
          ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT AND ANY
          CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH
          OTHER NAME AS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE
          DEPOSITORY TRUST COMPANY AND ANY PAYMENT IS MADE TO CEDE & CO., ANY
          TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
          ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO.,
          HAS AN INTEREST HEREIN."

     (b) Notwithstanding any other provision of this Section 203 or of Section
305, unless the terms of a Global Security expressly permit such Global Security
to be exchanged in whole or in part for individual Securities, a Global Security
may be transferred, in whole but not in part and in the manner provided in
Section 305, only to another nominee of the Depositary for such Global Security,
or to a successor Depositary for such Global Security selected or approved by
the Company or to a nominee of such successor Depositary.

     (c) (i) If at any time the Depositary for a Global Security notifies the
Company that it is unwilling or unable to continue as Depositary for such Global
Security or if at any time the Depositary for the Securities for such series
shall no longer be eligible or in good standing under the Exchange Act or other
applicable statute or regulation, the Company shall appoint a successor
Depositary with respect to such Global Security. If a successor Depositary for
such Global Security is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such ineligibility, the Company
will execute a Company Order for the authentication and delivery of Certificated
Securities of such series in exchange for such Global Security, and the Trustee,
upon receipt of such Company Order, will authenticate and deliver Certificated
Securities of such series of like tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of the Global Security
in exchange for such Global Security.

     (ii) If an Event of Default shall have occurred and be continuing or an
event shall have occurred which with the giving of notice or lapse of time or
both, would constitute an Event of Default with respect to the Securities
represented by such Global Security, the Trustee, upon receipt of a Company
Order for the authentication and delivery of Certificated Securities of such
series in exchange for such Global Security, will authenticate and deliver
Certificated Securities of such series of like tenor and terms in definitive
form in an aggregate principal amount equal to the principal amount of the
Global Security in exchange for such Global Security.


<PAGE>
                                      -15-


     (iii) The Company may at any time and in its sole discretion determine that
the Securities of any series issued or issuable in the form of one or more
Global Securities shall no longer be represented by such Global Security or
Securities. In such event the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of Certificated
Securities of such series in exchange in whole or in part for such Global
Security, will authenticate and deliver Certificated Securities of such series
of like tenor and terms in definitive form in an aggregate principal amount
equal to the principal amount of such Global Security or Securities representing
such series to be so exchanged for such Global Security or Securities.

     (iv) If specified by the Company pursuant to Section 301 with respect to
Securities issued or issuable in the form of a Global Security, the Depositary
for such Global Security may surrender such Global Security in exchange in whole
or in part for Certificated Securities of such series of like tenor and terms in
definitive form on such terms as are acceptable to the Company and such
Depositary. Thereupon the Company shall execute, and the Trustee shall
authenticate and deliver, without service charge, (1) to each Person specified
by such Depositary a new Certificated Security or Securities of the same series
of like tenor and terms and of any authorized denomination of $1,000 and any
integral multiple thereof as requested by such Person in aggregate principal
amount equal to and in exchange for such Person's beneficial interest in the
Global Security; and (2) to such Depositary a new Global Security of like tenor
and terms and in a denomination equal to the difference, if any, between the
principal amount of the surrendered Global Security and the aggregate principal
amount of Certificated Securities delivered to Holders thereof.

     (v) In any exchange provided for in any of the preceding four paragraphs,
the Company will execute and the Trustee will authenticate and deliver
Certificated Securities in definitive registered form in authorized
denominations of $1,000 and any integral multiple thereof. Upon the exchange of
a Global Security for Certificated Securities, such Global Security shall be
cancelled by the Trustee. Certificated Securities issued in exchange for a
Global Security pursuant to this Section 203 shall be registered in such names
and in such authorized denominations as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee. The Trustee shall deliver such Certificated
Securities to the Persons in whose names such Certificated Securities are so
registered.

     Securities bearing the manual or facsimile signatures of individuals who

<PAGE>
                                      -19-


     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established in or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
or by one or more indentures supplemental hereto as provided by Section 901, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, if it so requests, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating:

          (1) that such form has been established in conformity with the
     provisions of this Indenture;

          (2) that such terms have been established in conformity with the
     provisions of this Indenture;

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

          (4) that all laws and requirements in respect of the execution and
     delivery by the Company of the Securities have been complied with; and

          (5) such other matters as the Trustee may reasonably request.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

     Each Security shall be dated the date of its authentication unless
otherwise provided by the terms established and contemplated by Section 301.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual or facsimile signature, and such certificate
upon any Security shall be conclusive evidence, and the only


<PAGE>
                                      -20-



evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture.

SECTION 304. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and 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
temporary Securities of any series the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations. Until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

SECTION 305. Registration; Registration of Transfer and Exchange.

     The Company shall cause to be kept at one of its offices or agencies
maintained pursuant to Section 1002 or 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
Section 203 and to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities.
The Trustee initially is hereby appointed "Security Registrar" for the purpose
of registering Securities and transfers of Securities as herein provided. The
Company may act as Security Registrar and may change or appoint a Security
Registrar without prior notice to Holders or to the Trustee.

     Subject to Section 203, upon surrender for registration of transfer of any
Security of any series at the office or agency in a Place of Payment for that
series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.


<PAGE>
                                      -21-



     Subject to Section 203, at the option of the Holder, Securities of any
series may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor,
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.

     Subject to Section 203, all Securities issued upon any registration or
transfer or exchange of Securities shall be 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 203, 304, 906 or 1107 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption (under Section 1103) and
ending at the close of business on the day of such mailing, or (ii) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

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

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


<PAGE>
                                      -22-


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

     Upon the issuance of any new Security under this Section 306, 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 306 in
lieu of any destroyed, lost or stolen Security or in exchange for such mutilated
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 shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series duly issued hereunder.

     The provisions of this Section 306 are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307. Payment of Interest; Interest Rights Preserved.

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

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

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a special record date (a "Special Record Date") for the payment of such
     Defaulted Interest, which shall be fixed in the following manner. The
     Company shall notify the Trustee in writing of the amount of Defaulted
     Interest proposed to be paid on each Security of such series and the date
     of the proposed payment, and at the same time the Company shall deposit
     with the Trustee an amount of money equal to the aggregate amount proposed
     to be paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the date of the
     proposed payment, such money when depos-


<PAGE>
                                      -23-


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

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

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

SECTION 308. Persons Deemed Owners.

     Subject to Section 203, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 307) interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and none of the Company, the Trustee or any agent of the Company or the
Trustee shall be affected by notice to the contrary.

SECTION 309. Cancellation.

     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously


<PAGE>
                                      -24-


authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly cancelled
by the Trustee. No Securities shall be authenticated in lieu of or in exchange
for any Securities cancelled as provided in this section, except as expressly
permitted by this Indenture. The Trustee shall destroy cancelled Securities and
deliver a certificate of such destruction to the Company.

SECTION 310. Computation of Interest.

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

SECTION 311. CUSIP and ISIN Numbers.

     The Company in issuing the Securities may use "CUSIP" and/or "ISIN" numbers
(if then generally in use), and the Trustee shall use CUSIP or ISIN numbers, as
the case may be, in notices of redemption or exchange as a convenience to
Holders and no representation shall be made as to the correctness of such
numbers either as printed on the Securities or as contained in any notice of
redemption, exchange or conversion.

                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

SECTION 401. Satisfaction and Discharge of Indenture.

     This Indenture shall upon Company Request cease to be of further effect
with respect to any series of Securities (except as to (i) any surviving rights
of registration of transfer or exchange of Securities herein expressly provided
for, (ii) rights hereunder of Holders to receive payments of principal of, and
premium, if any, and interest on, Securities, and other rights, duties and
obligations of the Holders as beneficiaries hereof with respect to the amounts,
if any, so deposited with the Trustee, (iii) remaining obligations of the
Company to make mandatory sinking fund payments and (iv) the rights, obligations
and immunities of the Trustee hereunder), and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture with respect to any series of Securities, when:

     (1) either:

          (A) all Securities of such series theretofore authenticated and
     delivered (other than (i) Securities of such series which have been
     mutilated, destroyed, lost or stolen and which have been replaced or paid
     as provided in Section 306 and (ii) Securities of such series for whose
     payment money has


<PAGE>
                                      -25-


     theretofore been deposited in trust or segregated and held in trust by the
     Company and thereafter repaid to the Company or discharged from such trust,
     as provided in Section 1003) have been delivered to the Trustee for
     cancellation; or

          (B) all such Securities not theretofore delivered to the Trustee for
     cancellation:

               (i) have become due and payable,

               (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

               (i) money in U.S. dollars (or if the Securities are denominated
          in a currency other than U.S. dollars, an amount of the applicable
          currency) in an amount sufficient, or

               (ii) (a) U.S. Government Obligations which through the payment of
          interest and principal in respect thereof in accordance with their
          terms will provide not later than one day before the due date of any
          payment referred to in clause (B) of this subparagraph money in an
          amount, or (b) a combination of such money and such U.S. Government
          Obligations, 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 the entire indebtedness on such Securities not
     theretofore delivered to the Trustee for cancellation, for principal (and
     premium, if any) and interest to the date of such deposit (in the case of
     Securities which have become due and payable) or to the Stated Maturity or
     Redemption Date, as the case may be;

     (2) if all series of Securities are being discharged, the Company has paid
or caused to be paid all other sums payable hereunder by the Company; and


<PAGE>
                                      -26-


     (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 607, and, if money or
U.S. Government Obligations shall have been deposited with the Trustee pursuant
to subclause (B) of clause (1) of this Section 401, the obligations of the
Trustee under Section 402 and the next to last paragraph of Section 1003, shall
survive.

SECTION 402. Application of Trust Funds; Indemnification.

     (a) Subject to the provisions of the next to last paragraph of Section
1003, all money and U.S. Government Obligations deposited with the Trustee
pursuant to Section 401, 403 or 404 and all money received by the Trustee in
respect of U.S. Government Obligations deposited with the Trustee pursuant to
Section 401, 403 or 404 shall be held in trust and applied by it, in accordance
with the provisions of the Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of
the principal (and premium, if any) and interest for whose payment such money
has been deposited with or received by the Trustee or to make mandatory sinking
fund payments or analogous payments as contemplated by Section 403 or 404, but
such money need not be segregated from other funds except to the extent required
by law.

     (b) The Company shall pay and shall indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against U.S. Government Obligations
deposited pursuant to Section 401, 403 or 404, or the interest and principal
received in respect of such obligations other than any payable by or on behalf
of Holders.

     (c) The Trustee shall deliver or pay to the Company from time to time upon
Company Request any U.S. Government Obligations or money held by it as provided
in Section 401, 403 or 404 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, is then in excess of the amount thereof which then
would have been required to be deposited for the purpose for which such
obligations or money was deposited or received.

SECTION 403. Legal Defeasance and Discharge of Indenture.

     The Company shall be deemed to have paid and discharged the entire
indebtedness on all the Outstanding Securities on the first date that all of the
conditions set forth in the proviso below are satisfied, and the provisions of
this Indenture, as it relates to such Outstanding Securities, shall no longer be
in effect (and the Trustee, at the expense of the Com-


<PAGE>
                                      -27-


pany, shall at Company Request, execute proper instruments acknowledging the
same), except as to:

     (a) the rights of Holders of Securities to receive, from the trust funds
described in subparagraph (1) hereof, (i) payment of the principal of (and
premium, if any) and each installment of principal of (and premium, if any) or
interest on the Securities on the Stated Maturity of such principal or
installment of principal 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 305, 306, 1002 and 1003; and

     (c) the obligations of the Company to the Trustee under Section 607,

provided, however, that the following conditions shall have been satisfied:

          (1) the Company has, or caused to be, irrevocably deposited (except as
     provided in Section 402) with the Trustee as trust funds in trust,
     specifically pledged as security for, and dedicated solely to, the benefit
     of the Holders of the Securities,

               (i) money in U.S. Dollars (or if the Securities are denominated
          in a currency other than U.S. dollars, an amount of the applicable
          currency) in an amount sufficient, or

               (ii) (a) U.S. Government Obligations which through the payment of
          interest and principal in respect thereof in accordance with their

          payment referred to in Section 401(A) or (B) money in an amount, or
          (b) a combination of such money and such U.S. Government Obligations,
          sufficient, in the opinion of a nationally recognized firm of
          independent certified public accountants expressed in a written
          certification thereof delivered to the Trustee,

     to pay and discharge (A) the principal of (and premium, if any) and each
     installment of principal of (and premium, if any) and interest on the
     Outstanding Securities on the Stated Maturity of such principal or
     installment of principal or interest or on the applicable Redemption Date
     and (B) 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 of the Securities;

                                      -28-


          (2) such deposit shall not cause the Trustee with respect to the
     Securities to have a conflicting interest for purposes of the Trust
     Indenture Act with respect to the Securities;

          (3) such deposit will not result in a breach or violation of, or
     constitute a default under, any applicable laws, this Indenture or any
     other agreement or instrument to which the Company is a party or by which
     it is bound;

          (4) no Event of Default or event which with notice or lapse of time
     would become an Event of Default with respect to the Securities shall have
     occurred and be continuing on the date of such deposit; and

          (5) if the deposit referred to in subparagraph (1) of this Section 403
     is to be made on or prior to one year from the Stated Maturity for payment
     of principal of the Outstanding Securities, the Company has delivered to
     the Trustee an Opinion of Counsel with no material qualifications or a
     favorable ruling of the Internal Revenue Service, in either case to the
     effect that Holders of the Securities will not recognize income, gain or
     loss for federal income tax purposes as a result of such deposit,
     defeasance and discharge and will be subject to federal income tax on the
     same amount and in the same manner and at the same times, as would have
     been the case if such deposit, defeasance and discharge had not occurred.

SECTION 404. Covenant Defeasance of Certain Obligations.

     If this Section 404 is specified to be applicable to Securities of any
series, the Company may omit to comply with any term, provision or condition set
forth in the sections of this Indenture or such Security with respect to the
Securities of that series ("Covenant Defeasance") if:

          (1) the Company has deposited or caused to be irrevocably deposited
     with the Trustee as trust funds in trust, specifically pledged as security
     for, and dedicated solely to, the benefit of the Holders of the Securities
     of that series,

               (i) money in U.S. dollars (or if the Securities are denominated
          in a currency other than U.S. dollars, an amount of the applicable
          currency) in an amount sufficient, or

               (ii) (a) U.S. Government Obligations which through the payment of
          interest and principal in respect thereof in accordance with their
          terms will provide not later than one day before the due date of any
          payment referred to in Section 401(A) or (B) money in an amount, or
          (b) a combination of such money and such U.S. Government Obligation,
          sufficient, in the opinion of a


<PAGE>
                                      -29-


          nationally recognized firm of independent public accountants expressed
          in a written certification thereof delivered to the Trustee,

     to pay and discharge (A) the principal of (and premium, if any) and each
     installment of principal (and premium, if any) and interest on the
     Outstanding Securities of that series on the Stated Maturity of such
     principal or installment of principal or interest and (B) any mandatory
     sinking fund payments or analogous payments applicable to Securities of
     such series on the day on which such payments are due and payable in
     accordance with the terms of the Indenture and of such Securities;

          (2) such deposit shall not cause the Trustee with respect to the
     Securities of that series to have a conflicting interest for purposes of
     the Trust Indenture Act with respect to the Securities of any series;

          (3) such deposit will not result in a breach or violation of, or
     constitute a default under, any applicable laws, this Indenture or any
     other agreement or instrument to which the Company is a party or by which
     it is bound;

          (4) if the deposit referred to in subparagraph (1) of this Section 404
     is to be made on or prior to one year from the Stated Maturity for payment
     of principal of the Outstanding Securities, the Company has delivered to
     the Trustee an Opinion of Counsel with no material qualifications or a
     favorable ruling of the Internal Revenue Service, in either case to the
     effect that Holders of the Securities will not recognize income, gain or
     loss for federal income tax purposes as a result of such deposit and
     defeasance of certain obligations and will be subject to federal income tax
     on the same amount and in the same manner and at the same times, as would
     have been the case if such deposit and defeasance had not occurred; and

          (5) 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 Covenant Defeasance contemplated by
     this Section 404 have been complied with.

     In the event the Company effects Covenant Defeasance with respect to any
Securities and such Securities are declared due and payable because of the
occurrence of any Event of Default, other than an Event of Default with respect
to any covenant as to which there has been Covenant Defeasance, the U.S.
Government Obligations on deposit with the Trustee will be sufficient to pay
amounts due on such Securities at the time of the Stated Maturity but may not be
sufficient to pay amounts due on such Securities at the time of the acceleration
resulting from such Event of Default.

                                    REMEDIES

SECTION 501. Events of Default.

     "Event of Default" (except as otherwise specified or contemplated by
Section 301 for Securities of any series) wherever used herein with respect to
Securities of any series, means any one of the following events:

          (1) default in the payment of any interest upon any Security of that

          (4) default in the performance, or breach, of any material 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 series of Securities other than
     that series) for a period of 60 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 at least 25% in principal amount
     of the Outstanding Securities a written notice specifying such default or
     breach and requiring it to be remedied and stating that such notice is a
     "Notice of Default" hereunder;

          (5) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable bankruptcy, insolvency, reorganization
     or other similar law or (B) a decree or order adjudging the Company a
     bankrupt or insolvent, or approving as properly filed a petition seeking
     reorganization, arrangement, adjustment or composition of or in respect of
     the Company under any applicable law, or appointing a custodian, receiver,
     liquidator, assignee, trustee, sequestrator or other similar official of
     the Company or of any substantial part of its property, or ordering the
     winding up or liquidation of its affairs, and the continuance of any such
     decree or order for relief or any such other decree or order unstayed and
     in effect for a period of 60 consecutive days;

          (6) the commencement by the Company of a voluntary case or proceeding
     under any applicable bankruptcy, insolvency, reorganization or other
     similar law or of


<PAGE>
                                      -31-


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

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

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default under Section 501(5)
or (6)) with respect to Securities of any series at the time Outstanding occurs
and is continuing, then in every such case the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of that series
may declare the principal amount (or, if the Securities of that series are
Original Issue Discount Securities, such portion of the principal amount as may
be specified in the terms of that series) of all of the Securities of that
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), and upon any such declaration such
principal amount (or specified amount) shall become immediately due and payable.

     In the case of an Event of Default resulting under Section 501(5) or (6)
which occurs and is continuing with respect to Securities of any series at the
time Outstanding, then all unpaid principal of and accrued interest on all such
Outstanding Securities of that series shall become immediately due and payable
without any notice or other action on the part of the Trustee or the Holders of
any Securities of such series.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
article provided, the Holders of a majority in 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:


<PAGE>
                                      -32-


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

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

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

               (C) 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 and any predecessor
          Trustee hereunder and all sums due the Trustee and any predecessor
          Trustee under Section 607; and

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

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

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

     The Company covenants that if

          (1) default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 60 days, or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
or rates prescribed therefor in such Securities, and, in addition thereto, such

<PAGE>
                                      -33-


further amount as shall be sufficient to cover the costs and expenses of
collection, including all amounts due the Trustee and any predecessor Trustee
under Section 607.

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

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

SECTION 504. Trustee May File Proofs of Claim.

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

          (i) to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensa-


<PAGE>
                                      -34-


tion, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 607.

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

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

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

SECTION 506. Application of Money Collected.

     Any money collected by the Trustee pursuant to this article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities 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 and each
     predecessor Trustee under Section 607;

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

          THIRD: To the Company.

SECTION 507. Limitation on Suits.

          No Holder of any Security of any series shall have any right to
     institute any proceeding, judicial or otherwise, with respect to this
     Indenture, or for the appointment of a receiver or trustee, or for any
     other remedy hereunder, unless:

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, 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 such
Holders.

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

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 307)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.


<PAGE>
                                      -36-


SECTION 509. Restoration of Rights and Remedies.

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

SECTION 510. Rights and Remedies Cumulative.

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

SECTION 511. Delay or Omission Not Waiver.

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

SECTION 512. Control by Holders.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series (or if more than one series is affected thereby, of all series so
affected, voting as a single class) 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, however, that:

          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture, expose the Trustee to personal liability or be unduly
     prejudicial to Holders not joining therein; and


<PAGE>
                                      -37-


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

     Nothing in this Indenture shall impair the right of the Trustee to take any
other action deemed proper by the Trustee which is not inconsistent with such
direction.

SECTION 513. Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series affected thereby (voting as a single class) waive any
past default hereunder with respect to such series and its consequences, except
that the consent of the Holders of all of the Securities of such series affected
thereby is required to waive a default:

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

          (2) in respect of a covenant or provision hereof which under this
     article 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 514. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 514 shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Securities on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date). This Section 514 shall be in lieu of Section


<PAGE>
                                      -38-


315(e) of the Trust Indenture Act and such Section 315(e) is hereby expressly
excluded from this Indenture, as permitted by the Trust Indenture Act.

SECTION 515. Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE VI

                                   THE TRUSTEE

SECTION 601. Certain Duties and Responsibilities.

     (a) Except during the continuance of an Event of Default with respect to
the Securities of any series:

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture with respect to such
     series, and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

          (2) in the absence of negligence or bad faith on its part, the Trustee
     may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture; but in the case of any such certificates or opinions which
     by any provision hereof are specifically required to be furnished to the
     Trustee, the Trustee shall be under a duty to examine the same to determine
     whether or not they conform to the requirements of this Indenture.

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

                                      -39-


     (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent or bad faith action, its own
negligent or bad faith failure to act, or its own willful misconduct, except
that:

          (1) this Section 601(c) shall not be construed to limit the effect of
     Section 601(a);

          (2) the Trustee shall not be liable for any error or judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;

          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any series, determined as provided in Section 512, relating
     to the time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Indenture with respect to the Securities of such
     series; and

          (4) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

     (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
601.

SECTION 602. Notice of Defaults.

     Within 60 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit by mail to all
Holders of Securities of such series, as their names and addresses appear in the
Security Register, notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, except in
the case of a default in the payment of the principal of (or premium, if any) or
interest on any Security of such series or in the payment of any sinking fund
installment with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders of Securities of such series; and
provided further, however, that in the case of any default of the character
specified in Section 501(4) with respect to Securities of such series, no such
notice to Holders shall be


<PAGE>
                                      -40-


given until at least 30 days after the occurrence thereof. For the purpose of
this Section 602, the term "default" means any event which is, or after notice
or lapse of time or both would become, an Event of Default with respect to
Securities of such series.

SECTION 603. Certain Rights of Trustee.

     Subject to the provisions of Section 601:

          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any Board Resolution, resolution, Officers'
     Certificate, certificate, statement, instrument, Opinion of Counsel,
     opinion, report, notice, request, direction, consent, order, bond,

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

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

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

          (f) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney; and


<PAGE>
                                      -41-


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

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

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

SECTION 605. May Hold Securities.

     The Trustee, any Paying Agent, any Security Registrar or any other agent of
the Company, in its individual or any other capacity, may become the owner or
pledgee of Securities and, subject to Sections 608 and 612, may otherwise deal
with, and collect obligations owed to it by, the Company with the same rights it
would have if it were not Trustee, Paying Agent, Security Registrar or such
other agent.

SECTION 606. Money Held in Trust.

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

SECTION 607. Compensation and Reimbursement.

     The Company agrees:

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

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


<PAGE>
                                      -42-


          (3) to indemnify each of the Trustee and any predecessor Trustee for,
     and to hold it harmless against, any loss, liability or expense, arising
     out of or in connection with the acceptance or administration of the trust
     or trusts hereunder and the performance of its duties hereunder, including
     the costs and expenses of defending itself against any claim or liability
     in connection with the exercise or performance of any of its powers or
     duties hereunder, except to the extent any such loss, liability or expense
     is due to its own negligence, bad faith or willful misconduct.

     To ensure the performance of the obligations of the Company under this
section, the Trustee shall have a senior claim to which the Securities are
hereby made subordinate upon all property and funds held or collected by the
Trustee as such, except property and funds held in trust for the payment of
principal of, premium, if any, or interest on particular Securities.

SECTION 608. Disqualification; Conflicting Interests.

     The Trustee shall comply with the terms of Section 310(b) of the Trust
Indenture Act.

SECTION 609. Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be 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 exercise corporate trust powers having (or, in the case of the
subsidiary of a bank holding company that guarantees the obligations of the
Trustee under this Indenture, such holding company's parent shall have) a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by Federal or State authority. If such corporation or holding
company parent publishes reports of condition at least annually, pursuant to law
or the requirements of said supervising or examining authority, then for the
purposes of this section, the combined capital and surplus of such corporation
or holding company parent shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section 609, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article VI.

SECTION 610. Resignation and Removal; Appointment of Successor.

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

     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of accep-


<PAGE>
                                      -43-


tance by a successor Trustee required by Section 611 shall not have been
delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series. If the acceptance of appointment is substantially
contemporaneous with the resignation, then the notice called for by the first
sentence of this Section 610(b) may be combined with the instrument called for
by Section 611.

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

     (d) If at any time:

          (1) the Trustee shall fail to comply with Section 608 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;

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

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

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

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


<PAGE>
                                      -44-


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

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

SECTION 611. Acceptance of Appointment by Successor.

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

     (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the


<PAGE>
                                      -45-


provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

     (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
Section 611(a) or (b), as the case may be.

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

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

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

SECTION 613. Preferential Collection of Claims Against Company.

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


<PAGE>
                                      -46-


gor). A trustee who has resigned or been removed shall be subject to Section
311(a) of the Trust Indenture Act to the extent provided therein.

                                  ARTICLE VII

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 701. Company to Furnish Trustee Names and Addresses of Holders.

     The Company will furnish or cause to be furnished to the Trustee with
respect to the Securities of each series:

          (a) semi-annually, not more than fifteen days after each Regular
     Record Date, or, in the case of any series of Securities on which
     semi-annual interest is not payable, not more than fifteen days after such
     semi-annual dates as may be specified by the Trustee, a list, in such form
     as the Trustee may reasonably require, of the names and addresses of the
     Holders as of such Regular Record Date or such semi-annual date, as the
     case may be; and

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

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

SECTION 702. Preservation of Information; Communications to Holders.

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

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


<PAGE>
                                      -47-


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

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

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

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

     (d) Subject to Sections 601 and 702(a), (b) and (c), if the Company or any
other Person (other than the Trustee) shall desire to communicate with Holders
of Securities to solicit or obtain from them any proxy, consent, authorization,
waiver, approval of a plan of reorganization, arrangement or readjustment or
other action ("Holder Action"), the Trustee shall have no duty to participate in
such communication or solicitation or the processing of responses in any manner
except (i) to furnish the rules and regulations and to perform the


<PAGE>
                                      -48-


functions referred to in Section 104 and (ii) to receive (A) the instruments
evidencing the Holder Action together with (B) the Officers' Certificate and
Opinion of Counsel referred to below. The Company hereby covenants that any and
all communications and solicitations distributed by it in connection with any
Holder Action will comply in all material respects with applicable law,
including without limitation applicable law concerning adequacy of disclosure.
The Trustee shall have no responsibility for the accuracy or completeness of any
materials circulated to solicit any Holder Action nor for any related
communications nor for the compliance thereof with applicable law. No Holder
Action shall become effective until the Trustee shall have received from the
Company or other person who solicited the Holder Action (1) the instruments
evidencing such Holder Action and (2) (x) (in the case of Holder Action
solicited by the Company or the representative of the Company's estate if the
Company is the debtor in any bankruptcy or other insolvency proceeding) an
Officers' Certificate and (y) (in all cases) an Opinion of Counsel, each
specifying the Holder Action taken and stating that such Holder Action has been
duly and validly taken in compliance with this Indenture in all material
respects. Such Officers' Certificate, if any, shall also certify that (after
giving effect to such Holder Action) no Event of Default or event or condition
which, with notice or lapse of time or both, would become an Event of Default
has occurred and is continuing or has not been waived.

     (e) The Depositary may grant proxies and otherwise authorize its
participants which own the Global Securities to give or take any Act which a
Holder is entitled to take under this Indenture; provided, however, that the
Depositary has delivered a list of such participants to the Trustee.

SECTION 703. Reports by Trustee.

     (a) Within 60 days after [ ] of each year commencing with the first [ ]
following the date of this Indenture, the Trustee shall transmit by mail to all
Holders, as their names and addresses appear in the Security Register, a brief
report dated as of such [ ], to the extent required by Section 313(a) of the
Trust Indenture Act.

     (b) The Trustee shall comply with Sections 313(b) and 313(c) of the Trust
Indenture Act.

     (c) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with the Commission and with the Company. The
Company will notify the Trustee when any Securities are listed on any stock
exchange.

SECTION 704. Reports by Company.

     The Company shall:


<PAGE>
                                      -49-


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

          (2) file with the Trustee and the Commission, in accordance with the
     rules and regulations prescribed from time to time by the Commission, such
     additional information, documents and reports with respect to compliance by
     the Company with the conditions and covenants of this Indenture as may be
     required from time to time by such rules and regulations.

                                  ARTICLE VIII

                                CERTAIN COVENANTS

SECTION 801. Restrictions on Liens on Capital Stock of National Education
Loan Network.

     The Company shall not create or guarantee any indebtedness that is secured
by a lien on the Capital Stock of National Education Loan Network, unless the
Company also secures the Securities on a pro rata or priority basis with such
other secured indebtedness; provided, however, that the Company may grant liens
on such Capital Stock without also securing the Securities if the Board of
Directors determines that any such liens do not materially detract from or
interfere with the fair market value, or with control, of such Capital Stock.

SECTION 802. When Company May Merge or Transfer Assets.

     The Company shall not consolidate or merge with or into any other Person or
convey, transfer, sell or lease all or substantially all of its properties and
assets as an entirety to any Person or permit any Person to consolidate with or
merge into the Company, unless:

          (1) either (a) the Company shall be the surviving Person or (b) the
     Person (if other than the Company) formed by such consolidation or into
     which the Company is merged or the Person which acquires by conveyance,
     transfer, sale or lease of all or substantially all of the properties and
     assets of the Company shall be organized and


<PAGE>
                                      -50-


     existing under the laws of a domestic jurisdiction and shall expressly
     assume, by an indenture supplemental hereto, executed and delivered to the
     Trustee, in form reasonably satisfactory to the Trustee, all of the
     obligations of the Company under the Securities and this Indenture;

          (2) immediately after giving effect to such transaction, no Event of
     Default, and no event that, after notice or lapse of time or both, would
     become an Event of Default, shall have occurred and be continuing; and

          (3) the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel stating that such consolidation,
     merger, conveyance, transfer, sale or lease and, if a supplemental
     indenture is required in connection with such transaction, such
     supplemental indenture comply with this Section 801 and that all conditions
     precedent herein provided for relating to such transaction have been
     satisfied.

     The successor Person formed by such consolidation or into which the Company
is merged or the successor Person to which such conveyance, transfer, sale or
lease is made shall succeed to, and be substituted for, and may exercise every
right and power of, the Company under this Indenture with the same effect as if
such successor had been named as the Company herein; and thereafter, the Company
shall be discharged from all obligations and covenants under this Indenture and
the Securities. Subject to Section 903, the Company, the Trustee and the
successor Person shall enter into a supplemental indenture to evidence the
succession and substitution of such successor Person and such discharge and
release of the Company.

Holders.

     The Company, when authorized by a Board Resolution, and the Trustee, at any
time and from time to time, may amend or supplement this Indenture or the
Securities without the consent of any Holder, so long as such changes, other
than those in clause (2), do not materially and adversely affect the interests
of the Holder:

          (1) to cure any ambiguity, omission, defect or inconsistency;

          (2) to make any modifications or amendments that do not, in the good
     faith opinion of the Company's Board of Directors and the Trustee,
     adversely affect the interests of the Holders in any material respect;

          (3) to provide for the assumption of the Company's obligations under

          (7) to make any change necessary to comply with the Trust Indenture
     Act, or any amendment thereto, or to comply with any requirement of the
     Commission in connection with the qualification of this Indenture under the
     Trust Indenture Act; provided, however, that such modification or amendment
     does not, in the good faith opinion of the Company's Board of Directors and
     the Trustee, adversely affect the interests of the Holders of the
     Securities in any material respect;

          (8) to provide for uncertificated Securities in addition to or in
     place of Certificated Securities or to provide for bearer Securities;

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

          (10) to change or eliminate any of the provisions of this Indenture;

SECTION 902. Amendments or Supplemental Indentures with Consent of Holders.

     With the written consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of such series affected by such
amendment or supplement at the time Outstanding, the Company, when authorized by
a Board Resolution, and the Trustee, at any time and from time to time, may
amend or supplement this Indenture or such series of Securities. However,
without the consent of each Holder affected, an amendment to this Indenture or
the Securities may not:

          (1) change the Stated Maturity of the principal of, or any premium on,
     or any installment of interest with respect to the Securities;

          (2) reduce the principal amount of, or the rate of interest on, the
     Securities;

          (3) change the currency of payment of principal of or interest on the
     Securities;

          (4) impair the right to institute suit for the enforcement of any
     payment on or with respect to the Securities;

          (5) reduce the above-stated percentage of Holders of the Securities of
     any series necessary to modify or amend this Indenture;

          (6) modify the foregoing requirements or reduce the percentage of
     Outstanding Securities necessary to waive any covenant or past default; or

          (7) if the Securities are convertible, adversely affect the right to
     convert the Securities into shares of Common Stock or Preferred Stock in
     accordance with the provisions of this Indenture.

     It shall not be necessary for any Act of the Holders under this Section 902
to approve the particular form of any proposed amendment or supplemental
indenture, but it shall be sufficient if such Act approves the substance
thereof.

     After an amendment or supplemental indenture under this Section 902 becomes
effective, the Company shall mail to each Holder a notice briefly describing the
amendment or supplemental indenture.

     An amendment or supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be


<PAGE>
                                      -53-


deemed not to affect the rights under this Indenture of the Holders of
Securities of any other series.

SECTION 903. Execution of Supplemental Indentures.

     The Trustee shall sign any supplemental indenture authorized pursuant to
this article if the amendment contained therein does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign such supplemental indenture. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section
601) shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture.

SECTION 904. Effect of Supplemental Indentures.

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

SECTION 905. Conformity with Trust Indenture Act.

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

SECTION 906. Reference in Securities to Supplemental Indentures.

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article IX may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to
any matter provided for in such supplemental indenture. If the Company shall so
determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

                                    ARTICLE X

                                    COVENANTS

SECTION 1001. Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture. At the option of the Company,
payment of principal (and premium, if any) and interest on the Securities may be
made either by wire transfer or (subject to collection) by check mailed to the
address of the Person entitled thereto at such address as shall appear in the
Security Register.

SECTION 1002. Maintenance of Office or Agency.

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for 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 hereby initially appoints the Trustee
its office or agency for each of said purposes. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands. The Company may also from time to time designate one or
more other offices or agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in each Place of Payment for Securities of any series for
such purposes. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

SECTION 1003. Money for Securities; Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any)


<PAGE>
                                      -55-


or interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee of
its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, on or prior to each due date of the principal of (and
premium, if any) or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

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

          (1) hold all sums held by it for the payment on the principal of (and
     premium, if any) or interest on Securities of that series in trust for the
     benefit of the Persons entitled thereto until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided;

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

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

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

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or 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


<PAGE>
                                      -56-


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 mailed or published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the City, County and State of New
York, or both, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
mailing or publication, any unclaimed balance of such money then remaining will
be repaid to the Company.

     The Company shall have no obligation to make payment of principal of (or
premium, if any) or interest on any Security in immediately available funds,
except that if the Company shall have received original payment for Securities
in immediately available funds it shall make available immediately available
funds for payment of the principal of such Securities.

SECTION 1004. Corporate Existence.

     Subject to Article VIII, 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 or senior management of the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders.

SECTION 1005. Maintenance of Properties.

     The Company will use its reasonable efforts to cause all material
properties used or useful in the conduct of its business to be maintained and
kept in good condition, repair and working order (subject to wear and tear) and
supplied with all necessary material equipment and will use its reasonable
efforts to cause to be made all necessary material repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section 1005 shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business and not disadvantageous in any material respect to the Holders.


<PAGE>
                                      -57-


SECTION 1006. Statement by Officers as to Default.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, a certificate of
the principal executive officer, principal financial officer or principal
accounting officer of the Company stating whether or not to the best knowledge
of the signer thereof the Company is in default in the performance and
observance of any of the terms, provisions and conditions of this Indenture, 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 1007. Waiver of Certain Covenants.

     In respect of any series of Securities, the Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Section 1006 if before or after the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Securities of such
series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

SECTION 1101. Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article XI. In addition, unless expressly prohibited in an
indenture supplement hereto or in the authorizing resolutions with respect to
any series of Securities, the Company may purchase, acquire or otherwise hold
Securities.

SECTION 1102. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution. In case of any redemption at the election of the Company of
less than all the Securities of any series, the Company shall, at least 30 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed, such notice
to be accompanied by a written statement signed by an authorized officer of the
Company stating that no defaults in the payment of interest or Events of Default

<PAGE>
                                      -58-


with respect to the Securities of that series have occurred (which have not been
waived or cured). 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 to the
Trustee an Officers' Certificate evidencing compliance with such restriction.

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

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

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

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

SECTION 1104. Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not such
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to any such Holder in respect of any Security, shall not affect the
validity of the proceedings for the redemption of any other Security.

     All notices of redemption shall state:

          (1) the Redemption Date;

          (2) the Redemption Price and any accrued interest;


<PAGE>
                                      -59-


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

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

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

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

          (7) the CUSIP number and, if applicable, the ISIN number of the
     Securities being redeemed.

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

SECTION 1105. Deposit of Redemption Price.

     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 1003) an amount of
money, in funds immediately available on the due date, sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Securities which are to be redeemed
on that date.

SECTION 1106. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified together with accrued interest thereon, and
from and after such date (unless the Company shall default in the payment of the
Redemption Price and accrued interest) such Securities shall cease to bear
interest. Upon surrender of any such Security for redemption in accordance with
said notice, such Security shall be paid by the Company at the Redemption Price,
together with accrued interest to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on the Redemption Date shall
be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.


<PAGE>
                                      -60-


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

     The Trustee shall not redeem any Securities of any series pursuant to this
article (unless all Outstanding Securities of such series are to be redeemed) or
mail or give any notice of redemption of Securities during the continuance of an
Event of Default hereunder known to the Trustee with respect to such series,
except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided, however, that it shall have received from the Company
a sum sufficient for such redemption. Except as aforesaid, any moneys
theretofore or thereafter received by the Trustee shall, during the continuance
of such Event of Default, be deemed to have been collected under Article V and
held for the payment of all such Securities of such series. In case such Event
of Default shall have been waived as provided in Section 513 or the default
cured on or before the 60th day preceding the Redemption Date, such moneys shall
thereafter be applied in accordance with the provisions of this article.

SECTION 1107. Securities Redeemed in Part.

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

                                  ARTICLE XII

                                  SINKING FUNDS

SECTION 1201. Applicability of Article.

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

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

to reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.

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

SECTION 1203. Redemption of Securities for Sinking Fund.

     Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company (1) will deliver to the Trustee an Officers'
Certificate (A) stating that no defaults in the payment of interest or Events of
Default with respect to Securities of that series have occurred (which have not
been waived or cured), (B) specifying the amount of the next ensuing sinking
fund payment for that series pursuant to the terms of Securities of that series,
(C) stating whether or not the Company intends to exercise its right, if any, to
make an optional sinking fund payment with respect to such series on the next
ensuing sinking fund payment date and, if so, specifying the amount of such
optional sinking fund payment and (D) specifying the portion of such sinking
fund payment, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 1202 and (2) 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 of such
series to be redeemed upon such sinking fund payment date in the manner
specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1105, 1106 and 1107. Failure of the Company, on or before any such 60th day, to
deliver such Officers' Certificate and Securities specified in this section, if
any, shall not constitute a default but shall constitute, on and as of such
date, the irrevocable election of the Company (a) that the mandatory sinking
fund payment for such series due on the next succeeding sinking fund payment
date shall be paid entirely in cash without the option to deliver or credit
Securities of such se-

                                      -62-


ries in respect thereof and (b) that the Company will make no optional sinking
fund payment with respect to Securities of such series as provided in this
article.

     The Trustee shall not redeem or cause to be redeemed any Security of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
with respect to such series except that, where the mailing of notice of
redemption of any Securities shall theretofore have been made, the Trustee shall
redeem or cause to be redeemed such Securities, provided that it shall have
received from the Company a sum sufficient for such redemption. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any
such default or Event of Default shall occur, and any moneys thereafter paid
into the sinking fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article V and held for the
payment of all such Securities of such series. In case such Event of Default
shall have been waived as provided in Section 513 or the default cured on or
before the 60th day preceding the sinking fund payment date, such moneys shall
thereafter be applied on the next succeeding sinking fund payment date in
accordance with this section to the redemption of such Securities.

     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.
