     Section 103.  Form of Documents Delivered to Trustee.
                   --------------------------------------

     In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by 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 Corporation or the
Guarantor 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 the matters upon which such
officer's certificate or opinion is based are erroneous. Any such certificate 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 Corporation or the Guarantor stating that the information with respect to
such factual matters is in the possession of the Corporation or the Guarantor,
as the case requires, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

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

     Whenever, subsequent to the receipt by the Trustee of any Board Resolution,
Officers' Certificate, Opinion of Counsel or other document or instrument, a
clerical, typographical or other inadvertent or unintentional error or omission
shall be discovered therein, a new document or instrument may be substituted
therefor in corrected form with the same force and effect as if originally filed
in the corrected form and, irrespective of the date or dates of the actual
execution and/or delivery thereof, such substitute document or instrument shall
be deemed to have been executed and/or delivered as of the date or dates
required with respect to the document or instrument for which it is substituted.
Anything in this Indenture to the contrary notwithstanding, if any action has
been taken by or at the request of the Corporation or the Guarantor in reliance
on an error or omission in the original document which has been corrected as
aforesaid, the action so taken shall not be invalidated or otherwise rendered
ineffective but shall be and remain in full force and effect, except to the
extent that such action was a result of willful misconduct or bad faith. Without
limiting the generality of the foregoing, any Securities or Guarantees issued
under the authority of such defective document or instrument shall nevertheless
be the valid obligations of the Corporation or the Guarantor, as the case may
be, entitled to the benefits of this Indenture equally and ratably with all
other Outstanding Securities or Guarantees, as the case may be, except as
aforesaid.

     Section 104.  Acts of Holders; Record Dates.
                   -----------------------------

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such

                                      -8-
<PAGE>

Holders in person or by agent duly appointed in writing; and, except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Corporation and the Guarantor. 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, the Corporation
and the Guarantor, if made in the manner provided in this Section.

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

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

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

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

                                      -9-
<PAGE>

cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of Securities of the relevant series in the manner set forth in Section
106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction or to revoke
the same, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date. Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Corporation's or Guarantor's expense, shall cause notice of such record date,
the proposed action by Holders and the applicable Expiration Date to be sent to
the Corporation and the Guarantor in writing and to each Holder of Securities of
the relevant series in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and

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 (if any), and not earlier than the earliest date (if any),
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 by
such Holders or the Corporation with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

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

Security issued upon the registration of transfer hereof or in exchange therefor

Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee, such Holder or Holders shall have offered the Trustee
reasonable indemnity, and the Trustee, for 60 days after its receipt of such
notice, shall not have received from the Holders of a majority in principal
amount of Securities of this series at the time Outstanding a direction
inconsistent with such request, and the Trustee shall have failed to institute
any such proceeding, for 60 days after receipt of such notice, request and offer
of indemnity. The foregoing shall not apply to any suit instituted by the Holder
of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

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

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

         The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

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

         Prior to due presentment of this Security for registration of transfer,
the Corporation, the Trustee and any agent of the Corporation or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes, whether or not this Security be

overdue, and neither the Corporation, the Trustee nor any such agent shall be
affected by notice to the contrary.

the laws of the State of New York, without regard to conflict of law principles
thereof.

such Security and of the Indenture. In case of the failure of the Corporation
punctually to make any such payment of principal, premium, if any, or interest,

with respect thereto, by the Holder of such Security or the Trustee or any other
circumstance which may otherwise constitute a legal or equitable discharge or
defense of a surety or guarantor; provided, however, that notwithstanding the
foregoing, no such waiver, modification or indulgence shall, without the consent
of the undersigned, increase the principal amount of such Security, or increase
the interest rate thereon, or change any redemption provisions thereof
(including any change to increase any premium payable upon redemption thereof),
or change the Stated Maturity thereof, or change the amount of principal of such
Security that would be due and payable upon a declaration of acceleration
thereof pursuant to Article V of the Indenture. The undersigned hereby waives
the benefits of diligence, presentment, demand for payment or performance, any
requirement that the Trustee or any of the Holders exhaust any right or take any
action against the Corporation or any other Person, filing of claims with a
court in the event of insolvency or bankruptcy of the Corporation, any right to
require a proceeding first against the Corporation, protest or notice with
respect to such Security or the indebtedness evidenced thereby and all demands
whatsoever, and covenants that this Guarantee will not be discharged Security

principal of and premium, if any, interest and sinking fund payment, if any, on
such Security.

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

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

     The obligations of the undersigned to the Holder of such Security and to
the Trustee pursuant to this Guarantee and the Indenture are expressly set forth
in Article XIV of the Indenture and reference is hereby made to the Indenture
for the precise terms of this Guarantee and all of the other provisions of the
Indenture to which this Guarantee relates.

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

          IN WITNESS WHEREOF, the undersigned has caused this Guarantee to be
duly executed.

         date for any purpose thereunder or hereunder, including the principal

         Securities and, in such case, the respective Depositary or Depositaries
         for such Global Securities, the form of any legend or legends which
         shall be borne by any such Global Security in addition to or in lieu of
         that set forth in Section 204 and any circumstances in addition to or
         in lieu of those set forth in Clause (2) of the last paragraph of
         Section 305 in which any such Global Security may be exchanged in whole
         or in part for Securities registered, and any transfer of such Global

                                      -21-
<PAGE>

         Security in whole or in part may be registered, in the name or names of
         Persons other than the Depositary for such Global Security or a nominee
         thereof;

               (18) any addition, modification or deletion of any Events of
         Default or covenants provided with respect to any Securities of the
         series and any change in the right of the Trustee or the requisite
         Holders of such Securities to declare the principal amount thereof due

               (19) any addition to or change in the covenants set forth in
         Article X which applies to Securities of the series; and

               (20) any terms of the Guarantees with respect to the Securities
         of such series in addition to those set forth in Section 1401, or any
         exceptions to or changes in those set forth in Section 1401; and

               (21) any other terms of the series.

         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set
forth, or determined in the manner provided, in the Officers' Certificate
referred to above or in any such indenture supplemental hereto.

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

         With respect to Securities of a series offered in a Periodic Offering,
the Board Resolution (or action taken pursuant thereto), Officers' Certificate
or supplemental indenture referred to above may provide general terms or
parameters for Securities of such series and provide either that the specific
terms of particular Securities of such series shall be specified in a Company
Order or that such terms shall be determined by the Corporation in accordance
with other procedures specified in a Company Order as contemplated by the third
paragraph of Section 303.

         Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, a series of Securities may from
time to time be "re-opened" and the aggregate principal amount of any such
series of Securities may be increased and additional Securities of such series
may be issued up to the maximum aggregate principal amount authorized with
respect to such series as increased.

         Section 302.  Denominations.
                       -------------

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

         Section 303.   Execution, Authentication, Delivery and Dating.
                        ----------------------------------------------

         The Securities shall be executed on behalf of the Corporation by its
Chairman of the Board, its Vice Chairman of the Board, its Chief Executive
Officer, its President or one of its Vice Presidents (which may be by facsimile)
attested by its Secretary or one of its Assistant Secretaries. The signature of
any of these officers on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Corporation shall bind the
Corporation, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

         Unless otherwise provided as contemplated by Section 301, with respect
to any series of Securities, the Guarantees to be endorsed on any series of
Securities shall be executed and delivered in accordance with the provisions of
Section 1402.

         At any time and from time to time after the execution and delivery of
this Indenture, the Corporation may deliver Securities of any series executed by
the Corporation with the Guarantees executed by the Guarantor, to the Trustee
for authentication, together with a Company Order and a Guarantor Order for the
authentication and delivery of such Securities and for the delivery of the
Guarantees endorsed thereon, and the Trustee in accordance with the Company
Order and the Guarantor Order shall authenticate such Securities and deliver
such Securities and Guarantees endorsed thereon, provided, however, that in the
case of Securities offered in a Periodic Offering, the Trustee shall
authenticate such Securities and deliver such Securities and Guarantees endorsed
thereon from time to time in accordance with such other procedures (including,
without limitation, the receipt by the Trustee of electronic instructions from
the Corporation or its duly authorized agents, promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Company Order
and a Guarantor Order delivered to the Trustee prior to the time of the first
authentication of Securities of such series. If the form or terms of the
Securities of the series or the Guarantees endorsed thereon have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities and the Guarantees
endorsed thereon and accepting the additional responsibilities under this
Indenture in relation to such Securities and the Guarantees endorsed thereon,
the Trustee shall be furnished, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel stating,

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

               (2)  if the terms of such Securities or Guarantees have been, or
         in the case of Securities of a series offered in a Periodic Offering,
         will be, established by or pursuant to Board Resolution as permitted by
         Section 301, that such terms have been, or in the case of Securities of
         a series offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject, in the case
         of Securities of a series offered in a Periodic Offering, to any
         conditions specified in such Opinion of Counsel; and

                                      -23-
<PAGE>

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

         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.

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

         With respect to Securities of a series offered in a Periodic Offering,
the Trustee may rely, as to the authorization by the Corporation and the
Guarantor of any of such Securities and Guarantees endorsed thereon, the forms
and terms thereof and the legality, validity, binding effect and enforceability
thereof, upon the Opinion of Counsel and the other documents delivered pursuant
to Sections 201 and 301 and this Section, as applicable, in connection with the
first authentication of Securities of such series.

         Each Security shall be dated the date of its authentication.

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

         Section 304.   Temporary Securities.
                        --------------------

         Pending the preparation of definitive Securities of any series, the
Corporation may execute, and upon Company Order and Guarantor Order the Trustee
shall authenticate and

                                      -24-
<PAGE>

deliver, temporary Securities (with temporary Guarantees endorsed thereon) which
are printed, lithographed, typewritten, mimeographed or otherwise produced, in
any authorized denomination, substantially of the tenor of the definitive
Securities and Guarantees in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities or Guarantees, as the case may be, may
determine, as evidenced by their execution of such Securities or Guarantees, as
the case may be.

          If temporary Securities or Guarantees of any series are issued, the
Corporation will cause definitive Securities and Guarantees of that series to be
prepared without unreasonable delay. After the preparation of definitive
Securities and Guarantees of such series, the temporary Securities and
Guarantees of such series shall be exchangeable for definitive Securities of
such series, with the definitive Guarantees of the Guarantor endorsed thereon,
upon surrender of the temporary Securities of such series at the office or
agency of the Corporation 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 Corporation shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive Securities
of the same series, of any authorized denominations and of like tenor and
aggregate principal amount, with the definitive Guarantees executed by the
Guarantor endorsed thereon. Until so exchanged, the temporary Securities of any
series and the Guarantees endorsed thereon shall in all respects be entitled to
the same benefits under this Indenture as definitive Securities of such series
and tenor and definitive Guarantees.

          Section 305.   Registration, Registration of Transfer and Exchange.
                         ---------------------------------------------------

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

          Upon surrender for registration of transfer of any Security of a
series at the office or agency of the Corporation in a Place of Payment for that
series, the Corporation 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 like
tenor and aggregate principal amount, with the Guarantees executed by the
Guarantor endorsed thereon.

          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
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Corporation shall execute, and the Trustee shall
authenticate and deliver, the Securities, with the Guarantees of the Guarantor
endorsed thereon, which the Holder making the exchange is entitled to receive.

                                      -25-
<PAGE>

          All Securities and Guarantees issued upon any registration of transfer
or exchange of Securities and the Guarantees endorsed thereon shall be the valid
obligations of the Corporation and the Guarantor, respectively, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the
Securities and Guarantees 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 Corporation, the Guarantor or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form satisfactory to the Corporation, the Guarantor and the Security
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing.

          No service charge shall be assessed against the Holder for any
registration of transfer or exchange of Securities, but the Corporation may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Securities, other than exchanges pursuant to Section 304, 906 or
1106 not involving any transfer.

          If the Securities of any series (or of any series and specified tenor)
are to be redeemed, the Corporation shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption and ending at the close of business on
the day of such mailing, or (B) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

         The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

               (1)  Each Global Security authenticated under this Indenture
         shall be registered in the name of the Depositary designated for such
         Global Security or a nominee thereof and delivered to such Depositary
         or a nominee thereof or custodian therefor, and each such Global
         Security shall constitute a single Security for all purposes of this
         Indenture.

               (2)  Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (A) such
         Depositary has notified the Corporation that it is unwilling or unable
         to continue as Depositary for such Global Security and a successor
         Depositary has not been appointed by the Corporation within 90 days of
         receipt by the Corporation of such notification, (B) if at any time the
         Depositary ceases to be a clearing agency registered under the Exchange
         Act at a time when the Depositary is required to be so registered to
         act as such Depositary and no successor Depositary shall have been
         appointed by the Corporation within 90 days after it became aware of
         such cessation, (C) the Corporation, in its sole discretion, executes
         and delivers to the Trustee a Company Order to the effect that such

                                      -26-
<PAGE>

         Global Security, together with all other Global Securities of the same
         series, shall be exchangeable as described below, (D) an Event of
         Default has occurred and is continuing with respect to the Securities
         of such series, or (E) there shall exist such circumstances, if any, in
         addition to or in lieu of the foregoing as have been specified for this
         purpose as contemplated by Section 301. If any of the events described
         in clauses (A) through (E) of the preceding sentence occur, the
         beneficial owners of interests in the relevant Global Securities will
         be entitled to exchange those interests for definitive Securities and,
         without unnecessary delay but in any event not later than the earliest
         date on which those interests may be so exchanged, the Corporation will
         deliver to the Trustee definitive Securities in such form and
         denominations as are required by or pursuant to this Indenture, and of
         the same series, containing identical terms and in an aggregate
         principal amount equal to the principal amount of such Global
         Securities, such Securities to be duly executed by the Corporation. On
         or after the earliest date on which such beneficial interests may be so
         exchanged, such Global Securities shall be surrendered from time to
         time by the Depositary as shall be specified in the Company Order with
         respect thereto (which the Corporation agrees to deliver), and in
         accordance with any instructions given to the Trustee and the
         Depositary (which instructions shall be in writing but need not be
         contained in or accompanied by an Officers' Certificate or be
         accompanied by an Opinion of Counsel), as shall be specified in the
         Company Order with respect thereto to the Trustee, as the Corporation's
         agent for such purpose, to be exchanged, in whole or in part, for
         definitive Securities as described above without charge. The Trustee
         shall authenticate and make available for delivery, in exchange for
         each portion of such surrendered Global Security, a like aggregate
         principal amount of definitive Securities of the same series of
         authorized denominations and of like tenor as the portion of such
         Global Security to be exchanged. Promptly following any such exchange
         in part, such Global Security shall be returned by the Trustee to such
         Depositary or its custodian. If a definitive Security is issued in
         exchange for any portion of a Global Security after the close of
         business at the place where such exchange occurs on or after (i) any
         Regular Record Date for such Security and before the opening of
         business at that Place of Payment on the next Interest Payment Date, or
         (ii) any Special Record Date for such Security and before the opening
         of business at such Place of Payment on the related proposed date for
         the payment of Defaulted Interest, as the case may be, interest shall
         not be payable on such Interest Payment Date or proposed date for
         payment, as the case may be, in respect of such definitive Security,
         but shall be payable on such Interest Date or proposed date for
         payment, as the case may be, only to the Person to whom interest in
         respect of such portion of such Global Security shall be payable in
         accordance with the provisions of this Indenture.

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

               (4)   Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a Global
         Security or any portion thereof, whether pursuant to this Section,
         Section 304, 306, 906 or 1106 or otherwise, shall be authenticated and
         delivered in the form of, and shall be, a Global Security, unless such

                                      -27-
<PAGE>

         Security is registered in the name of a Person other than the
         Depositary for such Global Security or a nominee thereof.

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

         If any mutilated Security is surrendered to the Trustee, the
Corporation shall execute and the Trustee shall authenticate and deliver in
exchange therefor a new Security of the same series and of like tenor and
principal amount, having a Guarantee executed by the Guarantor endorsed thereon
and bearing a number not contemporaneously outstanding.

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

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

         Upon the issuance of any new Security under this Section, the
Corporation 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
reasonable expenses (including the fees and expenses of the Trustee) connected
therewith.

         Every new Security of any series and any Guarantee endorsed thereon
issued pursuant to this Section in lieu of any destroyed, lost or stolen
Security and any Guarantee endorsed thereon shall constitute an original
additional contractual obligation of the Corporation and the Guarantor,
respectively, whether or not the destroyed, lost or stolen Security or Guarantee
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 and the Guarantees endorsed on
such Securities.

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

         Section 307.  Payment of Interest; Interest Rights Preserved.
                       ----------------------------------------------

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, such payment to be made at the office or agency maintained
for such purpose pursuant to Section 1002; provided, however, that, at the
option of the Corporation, interest on

                                      -28-
<PAGE>

any series of Securities that bear interest may be paid (i) by check mailed to
the address of the Persons entitled thereto as such addresses shall appear on
the Security Register or (ii) by wire transfer at such place and to such account
at a banking institution in the United States as may be designated in writing to
the Trustee at least 15 days prior to the date for payment by the Persons
entitled thereto. Any such instructions given pursuant to clause (ii) shall
remain in effect until revoked by written notice to the Trustee at least 15 days
prior to any payment date by the Person entitled to such payment.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, 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
Corporation, at its election in each case, as provided in Clause (1) or (2)
below:

               (1)  The Corporation or the Guarantor may elect to make payment
         of any Defaulted Interest to the Persons in whose names the Securities
         of such series (or their respective Predecessor Securities) are
         registered at the close of business on a Special Record Date for the
         payment of such Defaulted Interest, which shall be fixed in the
         following manner. The Corporation or the Guarantor 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 Corporation or the Guarantor, as the
         case may be, shall deposit with the Trustee an amount of money equal to
         the aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as in this Clause provided. Thereupon the
         Trustee shall fix a Special Record Date for the payment of such
         Defaulted Interest which shall be not more than 15 days and not less
         than 10 days prior to the date of the proposed payment and not less
         than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Corporation and
         the Guarantor of such Special Record Date and, in the name and at the
         expense of the Corporation or the Guarantor, shall cause notice of the
         proposed payment of such Defaulted Interest and the Special Record Date
         therefor to be given to each Holder of Securities of such series in the
         manner set forth in Section 106, 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 Corporation or the Guarantor 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, if any, on which such Securities may be listed, and upon such
         notice as may be required by such exchange, if, after notice given by
         the Corporation or the Guarantor to the Trustee of the proposed payment
         pursuant to this Clause, such manner of payment shall be deemed
         practicable by the Trustee.

                                      -29-
<PAGE>

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

          Section 308.  Persons Deemed Owners.
                        ---------------------

          Prior to due presentment of a Security for registration of transfer,
the Corporation, the Guarantor, the Trustee and any agent of the Corporation,
the Guarantor or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of and any premium and (subject to Section 307) any interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and none of the Corporation, the Guarantor, the Trustee or any agent of
the Corporation, the Guarantor 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 canceled by it. The Corporation or the Guarantor may at
any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Corporation or the Guarantor may
have acquired in any manner whatsoever, and may deliver to the Trustee (or to
any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Corporation has not issued and
sold, and all Securities so delivered shall be promptly canceled by the Trustee.
No Securities shall be authenticated in lieu of or in exchange for any
Securities canceled as provided in this Section, except as expressly permitted
by this Indenture. All canceled Securities held by the Trustee shall be disposed
of as directed by a Company Order or Guarantor Order; provided, however, that
the Trustee shall not be required to destroy such canceled Securities.

          Section 310.  Computation of Interest.
                        -----------------------

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

          Section 311.  CUSIP Numbers.
                        -------------

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

     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 specified in such Company Request
(except as to those surviving rights and obligations specified below), and the
Trustee, at the expense of the Corporation, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture as to such series,
when

          (1)  either

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

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

                    (i)   have become due and payable, or

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

                    (iii) are to be called for redemption within one year under
           arrangements satisfactory to the Trustee for the giving of notice of
           redemption by the Trustee in the name, and at the expense, of the
           Corporation, and the Corporation, in the case of (B) above, has
           deposited or caused to be deposited with the Trustee as trust funds
           in trust for the purpose money in an amount sufficient to pay and
           discharge, and which shall be applied by the Trustee to pay and
           discharge, the entire indebtedness on such Securities not theretofore
           delivered to the Trustee for cancellation, for principal and any
           premium and interest to the date of such deposit (in the case of
           Securities which have become due and payable) or to the Stated
           Maturity or Redemption Date, as the case may be;

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

           (3) the Corporation has delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for

     series have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Corporation and the
Guarantor to the Trustee under Section 607, the obligations of the Corporation
to any Authenticating Agent under Section 614 and, if money shall have been
deposited with the Trustee pursuant to subclause (B) of Clause (1) of this
Section, the obligations of the Corporation and the Trustee with respect to the
Securities of such series under Sections 304, 305, 306, 402, 1002, 1003 and 1306
shall survive such satisfaction and discharge.

     Section 402.  Application of Trust Money.
                   --------------------------

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

     Section 501.  Events of Default.
                   -----------------

     "Event of Default," wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless it is specifically deleted or modified in the Board Resolution or
Officers' Certificate delivered to the Trustee prior to the issuance of such
series of Securities or supplemental indenture under which such series of
Securities is issued or has been deleted or modified in an indenture
supplemental hereto:

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

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

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

                                      -32-
<PAGE>

          (4)  default in the performance, or breach, of any covenant or
     warranty of the Corporation or the Guarantor 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 a series of
     Securities other than that series) or the Securities of that series, and
     continuance of such default or breach for a period of 60 days after there
     has been given, by registered or certified mail, to the Corporation and the
     Guarantor by the Trustee or to the Corporation, the Guarantor and the
     Trustee by the Holders of at least 25% in principal amount of the
     Outstanding Securities of that series a written notice specifying such
     default or breach and requiring it to be remedied and stating that such
     notice is a "Notice of Default" hereunder; or

          (5)  the cessation of effectiveness of the Guarantee endorsed on any
     Security of such series or the finding by any judicial proceeding that the
     Guarantee endorsed on any Security of such series is unenforceable or
     invalid or the denial or disaffirmation by the Guarantor of its obligations
     under the Guarantee endorsed on any Security of such series; or

          (6)  default occurs under any bond, note, debenture or other
     instrument evidencing any indebtedness for money borrowed by the
     Corporation or the Guarantor (including a default with respect to any other
     series of Securities issued under this Indenture), or under any mortgage,
     indenture or other instrument under which there may be issued or by which
     there may be secured or evidenced any indebtedness for money borrowed by
     the Corporation or the Guarantor (or the payment of which is guaranteed by
     the Corporation or the Guarantor), whether such indebtedness or guarantee
     exists on the date this Indenture or is issued or entered into following
     the date of this Indenture, if:

               (a)    either:

                      (i)    such default results from the failure to pay any
               such indebtedness when due; or

                      (ii)   as a result of such default the maturity of such
               indebtedness has been accelerated prior to its expressed
               maturity; and

               (b)    the principal amount of such indebtedness, together with
          the principal amount of any other such indebtedness in default for
          failure to pay any such indebtedness when due or the maturity of which
          has been so accelerated, aggregates at least $25 million; or

          (7)  the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Corporation or the Guarantor
     in an involuntary case or proceeding under any applicable federal or state

     Section 502.  Acceleration of Maturity; Rescission and Annulment.
                   --------------------------------------------------

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

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Event of Default giving rise to such declaration of
acceleration shall, without further act, be deemed to have been waived, and such
declaration and its consequences shall, without further act, be deemed to have
been rescinded and annulled, if

                                      -34-
<PAGE>

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

               (A)  all overdue interest on all Securities of that series which
          has become due otherwise than by such declaration of acceleration,

               (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, to the extent permitted by law, any interest
          thereon at the rate or rates prescribed therefor in such Securities
          or, if no such rate or rates are so provided, at the rate or
          respective rates, as the case may be, of interest borne by such
          Securities,

               (C)  to the extent that payment of such interest is lawful,
          interest upon overdue interest which has become due otherwise than by
          such declaration of acceleration at the rate or rates prescribed
          therefor in such Securities or, if no such rate or rates are so
          provided, at the rate or respective rates, as the case may be, of
          interest borne by such Securities, and

               (D)  all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel and any other amounts due the 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 or accrued and unpaid
     interest on 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 Corporation and the Guarantor jointly and severally covenant that if

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

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

          (3)  default is made in the deposit of any mandatory sinking fund
     payment applicable to any Security when due,

the Corporation or the Guarantor 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

                                      -35-
<PAGE>

principal and any premium and interest and, to the extent that payment of such
interest shall be legally enforceable, interest on any overdue principal and
premium and on any overdue interest, at the rate or rates prescribed therefor in
such Securities or, if no such rate or rates are so provided, at the rate or
respective rates, as the case may be, of interest borne by such Securities, and,
in addition thereto, such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 607.

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

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

     Section 504.  Trustee May File Proofs of Claim.
                   --------------------------------

     In case of any judicial proceeding relative to the Corporation or the
Guarantor (or any other obligor upon the Securities or the Guarantees), their
respective property or their respective creditors, the Trustee (irrespective of
whether the principal of such Securities shall then be due and payable as
therein expressed or by declaration of acceleration or otherwise and
irrespective of whether the Trustee shall have made any demand on the
Corporation for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization adjustment, composition or other similar
judicial proceeding relative to the Corporation or the Guarantor, the Trustee
(irrespective of whether the principal of such Securities shall then be due and
payable as therein expressed or by declaration of acceleration or otherwise and
irrespective of whether the Trustee shall have made any demand on the
Corporation or the Guarantor for the payment of overdue principal, premium, if
any, or interest) shall be authorized 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 of such series 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 of such Securities allowed in such judicial proceeding, to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute

                                      -36-
<PAGE>

the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 607.

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

                   -----------------------------------------------------------

or the Guarantees endorsed thereon may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or the Guarantees 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 any premium
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

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

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

          Third:  To the payment of the balance, if any, to the Corporation or
     any other Person or Persons legally entitled thereto.

                   -------------------

     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,

     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 of such
Holders.

Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated 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.

                   ----------------------------------

     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 Corporation, the Guarantor, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder
and thereafter all rights and remedies of the Trustee and the Holders shall
continue as though no such proceeding had been instituted.

Section 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

     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, to the
extent permitted by law, impair any such right or remedy or constitute a waiver
of any such Event of Default or an acquiescence therein.

     Every right and remedy given by this Article or by law to the Trustee or to
the Holders may, to the extent permitted by law, 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.

of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series; provided that

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

          (2)    subject to Section 601, the Trustee may take any other action
     deemed proper by the Trustee which is not inconsistent with such direction,

Outstanding Securities of any series with respect to which any default under
this Indenture shall have occurred and be continuing may, on behalf of the
Holders of all Securities of such series, waive such past default under this
Indenture with respect to such Securities and its consequences, except a default

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

                                      -39-
<PAGE>

          (2)    in respect of a covenant or provision hereof which under
     Article IX 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 be deemed not
to have occurred, and any Event of Default arising therefrom shall be deemed to
have been cured and not to have occurred, for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other default or impair any
right consequent thereon.

                   ---------------------

     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 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 and
disbursements, 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
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of 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, if any, on any
Security on or after the respective Stated Maturities expressed in such Security
(or, in the case of redemption, on or after the Redemption Date).

                   --------------------------------

     Each of the Corporation and the Guarantor 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 or any usury law or any other law wherever enacted, now or at any
time hereafter in force, which would prohibit or forgive the Corporation or the
Guarantor from paying all or any portion of the principal of or premium, if any,
or interest on any Securities as contemplated herein or therein or which may
affect the covenants or the performance of this Indenture; and each of the
Corporation and the Guarantor (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.

     Section 601.  Certain Duties and Responsibilities.
                   -----------------------------------

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any

                                      -40-
<PAGE>

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. The permissive right of the Trustee to do things enumerated in this
Indenture shall not be construed as a duty to do such things and in no event
shall the Trustee be liable for the consequences of any act or omission except
to the extent of the Trustee's negligence, negligent failure to act or willful
misconduct. 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.

                    ------------------

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

     Section 603.   Certain Rights of Trustee.
                    -------------------------

     Subject to the provisions of Section 601:

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

          (2)  any request or direction of the Corporation or the Guarantor
     mentioned herein shall be sufficiently evidenced by a Company Request or
     Company Order, or Guarantor Request or a Guarantor Order, as applicable, or
     as otherwise expressly provided herein, and any resolution of the Board of
     Directors shall be sufficiently evidenced by a Board Resolution;

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

          (4)  the Trustee may consult with counsel of its selection 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;

          (5)  prior to the occurrence of an Event of Default, the Trustee shall
     undertake to perform only such duties as are specifically set forth in this
     Indenture; and in case an

                                      -41-
<PAGE>

     Event of Default has occurred and is continuing with respect to the
     Securities of any series, the Trustee shall be under no obligation to
     exercise any of the rights or powers vested in it by this Indenture with
     respect to the Securities of such series, whether at the request or
     direction of any of the Holders thereof or pursuant to any other provision
     in 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;

          (6)  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, at reasonable times previously notified to the
     Corporation or the Guarantor, to examine the relevant books, records and
     premises of the Corporation or the Guarantor, personally or by agent or
     attorney;

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

          (8)  the Trustee shall not be deemed to have notice of any Default or
     Event of Default unless a Responsible Officer of the Trustee has actual
     knowledge thereof or unless written notice of any event which is in fact
     such a default is received by the Trustee at the Corporate Trust Office of
     the Trustee, and such notice references the Securities and this Indenture.

     The recitals contained herein and in the Securities and the Guarantees
endorsed thereon, except the Trustee's certificates of authentication, shall be

     Section 606.   Money Held in Trust.
                    -------------------

     Money held by the Trustee in trust hereunder need not be segregated from

liability for interest on any money received by it hereunder except as otherwise
agreed in writing by the Trustee with the Corporation or the Guarantor.

     Section 607.   Compensation, Reimbursement and Indemnity.
                    -----------------------------------------

     The Corporation and the Guarantor jointly and severally agree

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

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

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

     The Trustee shall have a first priority lien prior to the Securities upon
all property and funds held by it hereunder for any amount owing it or any
predecessor Trustee pursuant to this Section 607, except with respect to funds
held in trust for the benefit of the Holders of Securities.

     Without limiting any rights available to the Trustee under applicable law,
when the Trustee incurs expenses or renders services in connection with an Event
of Default specified in Section 501(7) or Section 501(8), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

     The provisions of this Section shall survive the termination of this
Indenture.

     Section 608.   Conflicting Interests.
                    ---------------------

     If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

                                      -43-
<PAGE>

To the extent permitted by such Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this Indenture with
respect to Securities of more than one series.

     Section 609.   Corporate Trustee Required; Eligibility.
                    ---------------------------------------

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

     Section 610.   Resignation and Removal; Appointment of Successor.
                    -------------------------------------------------

     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.

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

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

     If at any time:

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

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

          (3)  the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or

                                      -44-
<PAGE>

     any public officer shall take charge or control of the Trustee or of its
     property or affairs for the purpose of rehabilitation, conservation or
     liquidation,

then, in any such case, (A) the Corporation and the Guarantor by Board
Resolutions may remove the Trustee with respect to all Securities, or (B)
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.

     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 Corporation and the Guarantor, by
Board Resolutions, 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 Corporation and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements of
Section 611, become the successor Trustee with respect to the Securities of such
series and to that extent supersede the successor Trustee appointed by the
Corporation and the Guarantor. If no successor Trustee with respect to the
Securities of any series shall have been so appointed by the Corporation and the
Guarantor 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.

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

     Section 611.   Acceptance of Appointment by Successor.
                    --------------------------------------

     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 Corporation, the Guarantor and to the retiring
Trustee an instrument accepting such appointment, and thereupon the resignation
or removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee; but, on the
request of the Corporation, the Guarantor or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor

                                      -45-
<PAGE>

Trustee all property and money held by such retiring Trustee hereunder (subject
to the lien provided for in Section 607).

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

     Upon request of any such successor Trustee, the Corporation and the
Guarantor shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts referred to in the first or second preceding paragraph, as the case may
be.

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

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

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that
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

                                      -46-

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 Corporation.
                    -----------------------------------------------------

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

     Section 614.   Appointment of Authenticating Agent.
                    -----------------------------------

     The Trustee may appoint an Authenticating Agent or Agents acceptable to the
Corporation with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Corporation and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by federal or state
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

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

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee, the Corporation and the Guarantor. The Trustee may at
any time terminate the agency of an Authenticating Agent by giving written
notice thereof to such Authenticating Agent, the Corporation and the Guarantor.
Upon receiving such a notice of resignation or upon such a termination, or in
case at any time such Authenticating Agent shall cease to be eligible in

                                      -47-
<PAGE>

accordance with the provisions of this Section, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Corporation and
the Guarantor and shall give notice of such appointment in the manner provided
in Section 106 to all Holders of Securities of the series with respect to which
such Authenticating Agent will serve. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

     The Corporation and the Guarantor, jointly and severally, agree to pay to
each Authenticating Agent from time to time reasonable compensation for its
services under this Section.

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

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

Corporation may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be

shall not be less than three Business Days after the date any officer of the
Corporation actually receives such application, unless any such officer shall

         both, would become an Event of Default, has or shall have occurred and
         be continuing; and

               (iii) the Corporation or the Guarantor, as the case may be,
         shall deliver to the Trustee an Officers' Certificate and an Opinion of
         Counsel, each stating that such consolidation, merger, sale, transfer,
         lease or other conveyance and, if a supplemental indenture is required
         in connection with such transaction, such supplemental indenture comply
         with this Article and that all conditions precedent herein provided for
         relating to such transaction have been complied with.

         Upon any consolidation of the Corporation or the Guarantor with, or
merger of the Corporation or the Guarantor into, any other Person or any sale,

     Section 901. Supplemental Indentures Without Consent of Holders.
                  --------------------------------------------------

     Without the consent of any Holders, the Corporation and the Guarantor, when
authorized by Board Resolutions, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form
reasonably satisfactory to the Trustee, for any of the following purposes:

          (1)  to evidence the succession of another Person to the Corporation
     or the Guarantor, as the case may be, and the assumption by any such
     successor of the covenants of the Corporation or the Guarantor, as the case
     may be, herein and in the Securities or the Guarantees endorsed thereon, as
     the case may be; or

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

          (3)  to add any additional Events of Default for the benefit of the
     Holders of all or any series of Securities (and if such additional Events
     of Default are to be for the benefit of less than all series of Securities,
     stating that such additional Events of Default are expressly being included
     solely for the benefit of such series); or

          (4)  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

     and with or without interest coupons, or to facilitate the issuance of
     Securities in uncertificated form; or

          (5)  to change or eliminate any of the provisions of this Indenture in
     respect of one or more series of Securities, provided that any such change
     or elimination (A) shall neither (i) apply to any Security or Guarantee
     entitled to the benefit of such provision nor (ii) modify the rights of the
     Holder of any such Security or Guarantee with respect to such provision, or
     (B) shall become effective only when there is no such security outstanding
     or to add any new provision to this Indenture, provided that any such
     addition does not apply to any Security of any series or any Guarantee
     endorsed thereon created prior to the execution of such supplemental
     indenture; or

          (6)  to secure the Securities or the Guarantees; or

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

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

                                      -52-
<PAGE>

     change any of the provisions of this Indenture as shall be necessary to
     provide for or facilitate the administration of the trusts hereunder by
     more than one Trustee, pursuant to the requirements of Section 611; or

          (9)  to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture; provided that such action pursuant
     to this Clause (9) shall not adversely affect the interests of the Holders
     of Securities of any series in any material respect.

     Section 902. Supplemental Indentures With Consent of Holders.
                  -----------------------------------------------

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Corporation, the
Guarantor and the Trustee, the Corporation and the Guarantor, when authorized by
Board Resolutions, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture, or modifying in any manner the rights of the Holders of
Securities of such series under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby,

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

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

          (3)  modify or affect in any manner the terms and conditions of the
     obligations of the Guarantor in respect of the due and punctual payment of
     the principal of, or premium, if any, or interest on any Security, or

          (4)  modify any of the provisions of this Section, Section 513 or
     Section 1006, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived

     thereby; provided, however, that this clause (4) shall not be deemed to
     require the consent of any Holder with respect to changes in the references
     to "the Trustee" and concomitant changes in this Section and Section 1006,
     or the deletion of this proviso, in accordance with the requirements of
     Sections 611 and 901(8).

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

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

                  ------------------------------------

     In executing, or accepting the additional trusts created by, any

the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 315(a) through 315(d) of the Trust Indenture Act) shall
be fully protected in relying upon, an Opinion of Counsel and an Officers'
Certificate, each stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

     Section 904. Effect of Supplemental Indentures.
                  ---------------------------------

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

     Section 905. Conformity with Trust Indenture Act.
                  -----------------------------------

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

     Section 1001. Payment of Principal, Premium and Interest.
                   ------------------------------------------

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

     Section 1002. Maintenance of Office or Agency.
                   -------------------------------

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

     The Corporation or the Guarantor may also from time to time designate one
or more other offices or agencies where the Securities of one or more series may
be presented or surrendered for 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 Corporation or the Guarantor of its
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Corporation and the Guarantor
will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.

     Unless otherwise provided in or pursuant to Section 301 of this Indenture,
the Corporation and the Guarantor hereby designate as a Place of Payment for
each series of Securities the Borough of Manhattan, The City of New York, and
initially appoint the office of U.S. Bank Trust National Association in the
Borough of Manhattan, The City of New York, as its office or agency in that
Place of Payment for such purpose.

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

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

                                      -55-
<PAGE>

         Whenever the Corporation 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
or any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Corporation will promptly notify the Trustee of its action or
failure so to act.

         The Corporation 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) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2)
during the continuance of any default by the Corporation (or any other obligor
upon the Securities of that series) in the making of any payment in respect of
the Securities of that series, upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

         The Corporation 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 hereunder by the Corporation 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
Corporation 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.

         Subject to any applicable escheatment laws, any money deposited with
the Trustee or any Paying Agent, or then held by the Corporation, in trust for
the payment of the principal of or any premium or interest on any Security of
any series and remaining unclaimed for two years after such principal, premium
or interest has become due and payable shall be paid to the Corporation on
Company Request, or (if then held by the Corporation) shall be discharged from
such trust; and the Holder of such Security shall thereafter, as an unsecured
general creditor, look only to the Corporation and the Guarantor, jointly and
severally, for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Corporation 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 Corporation cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of
general circulation in the Borough of Manhattan, The City of New York, New York,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Corporation.

         Section 1004. Corporate Existence.
                       -------------------

         Subject to Article VIII, each of the Corporation and the Guarantor will
do or cause to be done all things necessary to preserve and keep in full force
and effect their corporate existence, rights (charter and statutory) and
franchises.

                       -----------------------------------

         Each of the Corporation and the Guarantor will deliver to the Trustee,
on or before October 15 of each calendar year or on or before such other day in
each calendar year as the Corporation, the Guarantor and the Trustee may from
time to time agree upon, an Officers' Certificate, stating whether or not to the
best knowledge of the signers thereof the Corporation or the Guarantor, as the
case may be, is in default in the performance and observance of any of the
terms, provisions and conditions of this Indenture (without regard to any period
of grace or requirement of notice provided hereunder) and, if the Corporation or
the Guarantor shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge.

         Section 1006. Waiver of Certain Covenants.
                       ---------------------------

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Corporation may, with respect to the Securities
of any series, omit in any particular instance to comply with any term,
provision or condition set forth in any covenant provided pursuant to Section
301(19) or 901(2) for the benefit of the Holders of such series if before the
time for such compliance the Holders of not less than 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, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Corporation 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 such Securities) in
accordance with this Article.

         Section 1102. Election to Redeem; Notice to Trustee.
                       -------------------------------------

         The election of the Corporation to redeem any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. In case of any redemption at the election of
the Corporation, the Corporation shall, at least 45 days prior to the Redemption
Date fixed by the Corporation (unless a shorter notice shall be satisfactory to
the Trustee in its sole and absolute discretion), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities (A) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, or (B) pursuant to an election of the Corporation
which is subject to a condition specified in the terms of such Securities or
elsewhere in this Indenture, the Corporation and the Guarantor shall each
furnish the Trustee with an

                                      -57-
<PAGE>

Officers' Certificate evidencing compliance with any such restriction or
condition applicable to it.

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

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by lot and which may provide
for the selection for redemption of a portion of the principal amount of any
Security of such series; provided that the unredeemed portion of the principal
amount of any Security shall be in an authorized denomination (which shall not
be less than the minimum authorized denomination) for such Security. If less
than all the Securities of such series and of a specified tenor are to be
redeemed (unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

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

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

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

         Section 1104. Notice of Redemption.
                       --------------------

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

         All notices of redemption shall state:

            (1)  the Redemption Date;

            (2)  the Redemption Price;

            (3)  if less than all the Outstanding Securities of any series and
         of a specified tenor consisting of more than a single Security are to
         be redeemed, the identification

                                      -58-
<PAGE>

         (and, in the case of partial redemption of any such Securities, the
         principal amounts) of the particular Securities to be redeemed and, if
         less than all the Outstanding Securities of any series and of a
         specified tenor consisting of a single Security are to be redeemed, the
         principal amount of the particular Security to be redeemed;

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

            (5)  the place or places where each such Security is to be
         surrendered for payment of the Redemption Price and accrued interest,
         if any, unless it shall have been specified as contemplated by Section
         301 with respect to such Securities that such surrender shall not be
         required;

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

            (7)  the CUSIP number of such Securities, if any, or any other
         numbers used by the Depositary to identify such securities; and

            (8)  such other matters as the Corporation shall deem desirable or
         appropriate.

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

         On or prior to any Redemption Date, the Corporation shall deposit, with
respect to the Securities of any series called for redemption pursuant to this
Section 1104, with the Trustee or with a Paying Agent an amount of money in the
applicable currency sufficient to pay the Redemption Price of, and any accrued
interest on, all such Securities or portion thereof which are to be redeemed on
that date.

         Section 1105. Securities Payable on Redemption Date.
                       -------------------------------------

         Notice of redemption having been given as aforesaid, the Securities or
portions thereof so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Corporation shall default in the payment of the Redemption Price and
accrued interest, if any) such Securities or portions thereof, if
interest-bearing, shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security or portion
thereof shall be paid by the Corporation at the Redemption Price, together with
accrued interest, if any, to the Redemption Date; provided, however, that no
such surrender shall be a condition to such payment if so specified as
contemplated by Section 301 with respect to such Security, and provided further
that, unless otherwise specified as contemplated by Section 301, installments of
interest whose Stated Maturity is on or prior to the Redemption Date will be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Regular
Record Dates according to their terms and the provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security or, if no rate is prescribed therefor in the Security, at the rate
of interest, if any, borne by such Security.

         Section 1106. 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 Corporation, the Guarantor or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Corporation, the Guarantor and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing), and
the Corporation shall execute, and the Trustee shall authenticate and deliver to
the Holder of such Security without service charge, a new Security or Securities
of the same series and of like tenor (and with a Guarantee executed by the
Guarantor endorsed thereon), of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered with the
Guarantee of the Guarantor endorsed thereon.

                                 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 any series except as otherwise specified as
contemplated by Section 301 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities 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 such Securities is herein referred to as an "optional sinking fund
payment." If provided for by the terms of any Securities, 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 as
provided for by the terms of such Securities.

         Section 1202. Satisfaction of Sinking Fund Payments with Securities.
                       -----------------------------------------------------

         The Corporation (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Corporation 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 any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as

                                      -60-
<PAGE>

specified in the Securities so to be redeemed, for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

     Section 1203. Redemption of Securities for Sinking Fund.
                   -----------------------------------------

     Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days prior to each such sinking
fund payment date, the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Corporation 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 and 1106.

                                 ARTICLE XIII.

                      DEFEASANCE AND COVENANT DEFEASANCE

     Section 1301. Applicability of Article.
                   ------------------------

     Unless, pursuant to Section 301, provision is made that either or both of
(A) defeasance of any Securities or any series of Securities under Section 1302
and (B) covenant defeasance of any Securities or any series of Securities under
Section 1303 shall not apply to such Securities of a series, then the provisions
of either or both of Sections 1302 and Section 1303, as the case may be,
together with Sections 1304 and 1305, shall be applicable to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article. Unless otherwise specified pursuant to Section 301, defeasance
under Section 1302 and covenant defeasance under Section 1303 may be effected
only with respect to all, and not less than all, the Securities of any series.
To the extent that the Corporation is permitted, pursuant to Section 301, to
defer interest payments, change the time for interest payments, or change the
Stated Maturity of the Securities of any series or any installment of principal
thereof, any such right shall terminate upon defeasance or covenant defeasance
of the Securities of that series as described below or upon satisfaction and
discharge with respect to the Securities of that series pursuant to Section 401.

     Section 1302. Defeasance and Discharge.
                   ------------------------

     On and after the date the conditions set forth in Section 1304 are
satisfied, the Corporation and the Guarantor may cause themselves to be
discharged from their obligations with respect to any Securities or any series
of Securities and the Guarantees endorsed thereon (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Corporation and
the Guarantor shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities and to have satisfied all their
other obligations under such Securities and the Guarantees endorsed thereon and
this Indenture insofar as such Securities

                                      -61-
<PAGE>

and the Guarantees endorsed thereon are concerned (and the Trustee, at the
expense of the Corporation and the Guarantor, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal of
and any premium and interest on such Securities when payments are due, (2) the
Corporation's, the Guarantor's and Trustee's obligations with respect to such
Securities and the Guarantees endorsed thereon under Sections 304, 305, 306,
1002, 1003 and 1306 and with respect to the Trustee under Section 607, (3) the
rights, powers, trusts, duties and immunities of the Trustee hereunder, and (4)
this Article. Subject to compliance with this Article, Defeasance with respect
to any Securities or any series of Securities and the Guarantees endorsed
thereon by the Corporation and the Guarantor is permitted under this Section
1302 notwithstanding the prior exercise by the Corporation of its rights under
Section 1303 with respect to such Securities. Following a Defeasance, payment of
such Securities may not be accelerated because of an Event of Default.

     Section 1303. Covenant Defeasance.
                   -------------------

     On and after the date the conditions set forth in Section 1304 are
satisfied, the Corporation and the Guarantor may cause themselves to be released
from their obligations under any covenants provided pursuant to Section 301(19)
or 901(2) with respect to any Securities and the Guarantees endorsed thereon or
any series of Securities for the benefit of the Holders of such Securities and
the occurrence of any event specified in Sections 501(4) (with respect to any
such covenants provided pursuant to Section 301(19), 901(2) or 501(9)) shall be
deemed not to be or result in an Event of Default with respect to such
Securities as provided in this Section (hereinafter called "Covenant
Defeasance"). For this purpose, such Covenant Defeasance means that, with
respect to such Securities and the Guarantees endorsed thereon, the Corporation
and the Guarantor may omit to comply with and shall have no liability in respect
of any term, condition or limitation set forth in any covenants added for the
benefit of the Securities of such series pursuant to any such specified Section
(to the extent so specified in the case of Section 501(4)), whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby. Following a Covenant Defeasance, payment of the
Securities may not be accelerated by reference to the covenant described in the
description of Covenant Defeasance above.

     Section 1304. Conditions to Defeasance or Covenant Defeasance.
                   -----------------------------------------------

     The following shall be the conditions to the application of Section 1302 or
Section 1303 to any Securities or any series of Securities, as the case may be,
and the Guarantees endorsed thereon:

          (1)  The Corporation or the Guarantor shall irrevocably have deposited
     or caused to be deposited with the Trustee as trust funds in trust for the
     purpose of making the following payments, specifically pledged as security
     for, and dedicated solely to, the benefit of the Holders of such
     Securities, (A) money in U.S. dollars in an amount, or

                                      -62-
<PAGE>

     (B) Government Obligations which through the scheduled payment of principal
     and interest in respect thereof in accordance with their terms will
     provide, not later than one day before the due date of any payment due in
     respect of such Securities, money in an amount, or (C) a combination
     thereof, in each case sufficient, without consideration of any
     reinvestments of such principal and interest, in the opinion of a
     nationally recognized firm of independent public accountants expressed in a
     written certification thereof delivered to the Trustee, to pay and
     discharge, and which shall be applied by the Trustee to pay and discharge,
     the principal of and any premium and interest on such Securities on the
     respective Stated Maturities or on any Redemption Date established pursuant
     to Clause (3) below, in accordance with the terms of this Indenture and
     such Securities, and any mandatory sinking fund payments or analogous
     payments applicable to such Securities when such payments are due and
     payable in accordance with the terms of this Indenture and of such
     Securities. As used herein, "Government Obligation" means (x) any security
     which is (i) a direct obligation of the United States of America or the
     government which issued the foreign currency in which such Securities are
     payable, for the payment of which its full faith and credit is pledged or
     (ii) an obligation of a Person controlled or supervised by and acting as an
     agency or instrumentality of the United States of America or such
     government which issued the foreign currency in which such Securities are
     payable, the timely payment of which is unconditionally guaranteed as a
     full faith and credit obligation by the United States of America or such
     other government, which, in either case (i) or (ii), is not callable or
     redeemable at the option of the issuer thereof, and (y) any depositary
     receipt issued by a bank (as defined in Section 3(a)(2) of the Securities
     Act) as custodian with respect to any Government Obligation which is
     specified in clause (x) above and held by such bank for the account of the
     holder of such depositary receipt, or with respect to any specific payment
     of principal of or interest on any Government Obligation which is so
     specified and held, provided that (except as required by law) such
     custodian is not authorized to make any deduction from the amount payable
     to the holder of such depositary receipt from any amount received by the
     custodian in respect of the Government Obligation or the specific payment
     of principal or interest evidenced by such depositary receipt.

          (2) No event which is, or after notice or lapse of time or both would
     become, an Event of Default with respect to such Securities or any
     Guarantee endorsed thereon shall have occurred and be continuing at the
     time of such deposit or, with regard to any such event specified in
     Sections 501(7) and (8), at any time on or prior to the 90th day after the
     date of such deposit (it being understood that this condition shall not be
     deemed satisfied until after such 90th day).

          (3) If the monies or Government Obligations or combination thereof
     deposited pursuant to Clause (1) above are sufficient to pay the principal
     of and premium, if any, and interest, if any, on such Securities provided
     such Securities are to be redeemed prior to Stated Maturity (other than
     from mandatory sinking fund payments or analogous payments), notice of such
     redemption shall have been duly given pursuant to this Indenture or
     irrevocable instructions to redeem such Securities on such Redemption Date
     and to provide notice of such redemption to Holders satisfactory to the
     Trustee shall have been made.

                                      -63-
<PAGE>

          (4) In the case of Defeasance pursuant to Section 1302, the
     Corporation shall have delivered to the Trustee an opinion of independent
     counsel stating that (x) the Corporation has received from, or there has
     been published by, the Internal Revenue Service a ruling, or (y) since the
     date of this Indenture there has been a change in applicable federal income
     tax law, in either case to the effect that, and based thereon such opinion
     of independent counsel shall confirm that, the Holders of such Outstanding
     Securities will not recognize income, gain or loss for federal income tax
     purposes as a result of such Defeasance and will be subject to federal
     income tax on the same amounts, in the same manner and at the same times as
     would have been the case if such Defeasance had not occurred; or, in the
     case of Covenant Defeasance pursuant to Section 1303, the Corporation shall
     have delivered to the Trustee an opinion of independent counsel to the
     effect that the Holders of such Outstanding Securities will not recognize
     income, gain or loss for federal income tax purposes as a result of such
     Covenant Defeasance and will be subject to federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if such Covenant Defeasance had not occurred.

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

     Section 1305.  Deposited Money and Government Obligations to Be Held in
                    --------------------------------------------------------
                    Trust; Miscellaneous Provisions.
                    -------------------------------

     Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 1304 in respect of any Securities shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (other than the Corporation acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon in respect of principal and any premium and interest,
but money so held in trust need not be segregated from other funds except to the
extent required by law.

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

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

     Section 1306. Reinstatement.
                   -------------

     If the Trustee or any Paying Agent is unable to apply any moneys or
Government Obligations deposited pursuant to Section 401 or 1304 to pay any
principal of or premium, if any, or interest, if any, on the Securities of any
series by reason of any legal proceeding or any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Corporation's or Guarantor's obligations under this
Indenture and the Securities of such series or the Guarantees endorsed thereon
shall be revived and reinstated as though no such deposit had occurred, until
such time as the Trustee or Paying Agent is permitted to apply all such moneys
and Government Obligations to pay the principal of and premium, if any, and
interest, if any, on the Securities of such series as contemplated by Section
402 or 1305, as the case may be, provided, however, that if either the
Corporation or the Guarantor makes any payment of the principal of or premium,
if any, or interest, if any, on the Securities of such series following the
reinstatement of its obligations as aforesaid, the Corporation, or the
Guarantor, as the case may be, shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the funds held by the Trustee or
Paying Agent, but shall not be entitled to enforce or to receive any payments
arising out of, or based upon, such right of subrogation until the principal of,
and premium, if any, and interest, if any, on all Securities of that series
shall have been paid in full.

                                 ARTICLE XIV.

                                   GUARANTEE

     Section 1401. Guarantee.
                   ---------

     The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated and delivered by the Trustee, and to the Trustee on
behalf of such Holder, the due and punctual payment of the principal of, and
premium, if any, and interest, if any, on such Security and of any sinking fund
payments thereon, in each case when and as the same shall become due and
payable, whether at the Stated Maturity, by declaration of acceleration, call
for redemption, or otherwise, in accordance with the terms of such Security and
of this Indenture. In case of the failure of the Corporation punctually to make
any such payment of principal, premium, if any, or interest if any, or any such
sinking fund payment, whether at the Stated Maturity, by declaration of
acceleration, call for redemption or otherwise, the Guarantor hereby agrees to
cause such payment to be made punctually when and as the same shall become due
and payable, whether at the Stated Maturity or by declaration of acceleration,
call for redemption or otherwise, and as if such payment were made by the
Corporation. The Guarantor hereby agrees that its obligations hereunder shall be
absolute and unconditional irrespective of, and shall be unaffected by, any
invalidity, irregularity or unenforceability of such Security or this Indenture,
or any failure to enforce any provisions of such Security or this Indenture, or
any waiver, modification or indulgence granted to the Corporation with respect
thereto, by the Holder of such Security or the Trustee or any other circumstance
which may otherwise constitute a legal or equitable discharge or defense of a

                                      -65-
<PAGE>

surety or guarantor; provided, however, that notwithstanding the foregoing, no
such waiver, modification or indulgence shall, without the consent of the
Guarantor, increase the principal amount of such Security, or increase the
interest rate thereon, or change any redemption provisions thereof (including
any change to increase any premium payable upon redemption thereof), or change
the Stated Maturity thereof, or change the amount and principal of such Security
that would be due and payable upon a declaration of acceleration or the maturity
thereof pursuant to Article V of this Indenture.

     The Guarantor hereby waives the benefits of diligence, presentment, demand
for payment or performance, any requirement that the Trustee or any of the
Holders exhaust any right or take any action against the Corporation or any
other Person, filing of claims with a court in the event of insolvency or
bankruptcy of the Corporation, any right to require a proceeding first against
the Corporation, protest or notice with respect to any Security or the
indebtedness evidenced thereby and all demands whatsoever, and covenants that
this Guarantee will not be discharged in respect of any Security except by
complete performance of the obligations contained in this Indenture, such
Security and in this Guarantee. This Guarantee shall constitute a guaranty of
payment and not of collection. The Guarantor hereby agrees that, in the event of
a default in payment of principal, or premium, if any, or interest, if any, on
any Security, whether at its Stated Maturity, by declaration of acceleration,
call for redemption, or otherwise, legal proceedings may be instituted by the
Trustee on behalf of, or by, the Holder of such Security, subject to the terms
and conditions set forth in this Indenture, directly against the Guarantor to
enforce this Guarantee without first proceeding against the Corporation.

     The obligations of the Guarantor hereunder with respect to any Security
shall be continuing and irrevocable until the date upon which the entire
principal of, premium, if any, and interest on such Security has been, or has
been deemed pursuant to the provisions of Article IV of this Indenture to have
been, paid in full or otherwise discharged, but subject to reinstatement of such
obligations on the terms and conditions set forth in Section 1306.

     The Guarantor shall be subrogated to all rights of the Holders of the
Securities upon which its Guarantee is endorsed against the Corporation in
respect of any amounts paid by the Guarantor on account of such Securities
pursuant to the provisions of its Guarantee or this Indenture; provided,
however, that the Guarantor shall not be entitled to enforce or to receive any
payments arising out of, or based upon, such right of subrogation until the
principal of, and premium, if any, and interest, if any, on all Securities
issued hereunder shall have been paid in full.

     This Guarantee shall remain in full force and effect and continue
notwithstanding any petition filed by or against the Corporation for liquidation
or reorganization, the Corporation becoming insolvent or making an assignment
for the benefit of creditors or a receiver or trustee being appointed for all or
any significant part of the Corporation's assets, and shall, to the fullest
extent permitted by law, continue to be effective or reinstated, as the case may
be, if at any time payment of any Security, is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by any
Holder of such Security, whether as a "voidable preference," "fraudulent
transfer," or otherwise, all as though such payment or performance had not been
made. In the event that any payment, or any part thereof, is rescinded, reduced,
restored or returned on a Security, such Security shall, to the fullest extent
permitted by law, be reinstated and deemed paid only by such amount paid and not
so rescinded, reduced, restored or returned.

     Section 1402. Execution and Delivery of Guarantees.
                   ------------------------------------

     The Guarantee to be endorsed on the Securities of each series shall include
or incorporate by reference the terms of the Guarantee set forth in Section 1401
and any other terms that may be set forth as established pursuant to Section
301. The Guarantor hereby agrees to execute its Guarantee, in a form set forth
in Section 204 or established pursuant to Section 201, to be endorsed on each
Security authenticated and delivered by the Trustee.

     The Guarantee shall be executed on behalf of the Guarantor by its Chairman
of the Board, its Vice Chairman of the Board, its President or its Vice
President, under its corporate seal reproduced thereon attested by its Secretary
or one of its Assistant Secretaries or by its Treasurer or one of its Assistance
Treasurers. The signature of any such officer on the Guarantee may be manual or
facsimile.

     A Guarantee bearing the manual or facsimile signature of an individual who
was at any time a proper officer of the Guarantor shall bind the Guarantor,
notwithstanding that any such individual has ceased to hold such offices prior
to the authentication and delivery of such Guarantee or did not hold such office
at the date of such Guarantee.

     The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee endorsed
thereon on behalf of the Guarantor. The Guarantor hereby agrees that its
Guarantee set forth in Section 1401 shall remain in full force and effect
notwithstanding any failure to endorse a Guarantee on any Security. The
Guarantor by its execution of this Indenture hereby authorizes the Corporation,
in the name and on behalf of the Guarantor, to confirm the applicable Guarantee
to the Holder of each Security authenticated and delivered hereunder by the
Corporation's execution and delivery of each such Security, with such Guarantee
endorsed thereon, authenticated and delivered by the Trustee.

Indenture or in any supplemental indenture, or in any Security, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Corporation or the Guarantor or of any successor corporation to
either of them, either directly or through the Corporation or the Guarantor or
any successor corporation to either of them, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that all such liability is
hereby expressly

waived and released as a condition of, and as a consideration for, the execution

Price, and (2) to exercise a portion of an Option by delivering that number of
Shares already owned by an Optionee having a Fair Market Value which shall equal

administration of this Plan.

the administration and interpretation of the Plan and the granting of Plan
Awards shall be final, conclusive, and binding on all interested parties.  The

         --------------
condition to the granting of any Plan Award, that a Participant hold the Plan
Awards for a period of six months following the date of such acquisition.  This
condition shall be satisfied with respect to an Option if at least six months
elapse from the date of acquisition of the Option to the date of disposition of
the Option (other than upon exercise or conversion) or its underlying equity
security.

exceed the number of Shares that remain available for issuance under this Plan.
The Company, during the term of this Plan, shall at all times reserve and keep
available sufficient Shares to satisfy the requirements of this Plan.

this Plan.  In the event that Shares issued under this Plan revert to the
Company prior to the Vest Date under a grant of Restricted Stock, such Shares
shall again be available for issuance under this Plan.

                        -------------------------------

    (a)  Term of Option.  The term of each Option shall be ten (10) years from
         --------------
the Date of Grant or such shorter term as may be determined by the Committee;
provided, however, in the case of an ISO granted to a Ten-Percent Shareholder,
the term of such ISO shall be five (5) years from the Date of Grant or such
shorter time as may be determined by the Committee.

    (b)  Exercise Price and Method of Payment.
         ------------------------------------

         (i)     Exercise Price.  The Exercise Price shall be such price as is
                 --------------
determined by the Committee in its sole discretion and set forth in the Stock
Option Agreement; provided, however, in the case of an ISO granted to any
Optionee and a Nonstatutory Option to an Optionee who is also a Covered
Employee, the Exercise Price shall not be less than 100% of the Fair Market
Value of the Shares subject to such Option on the Date of Grant (or 110% in the

                 -----------------
Option shall be made in cash, by certified check, or if authorized by the

by any other method of payment as may be permitted under applicable law and this
Plan and authorized by the Committee under Section 3(c) of this Plan.

                 ---------------------------------------------
granted hereunder shall be exercisable at such times under such conditions as
shall be determined by the Committee including, without limitation performance
criteria with respect to the Company and/or the Optionee and in accordance with
the terms of this Plan. To the extent that Options granted hereunder are ISOs,
the Committee shall designate such Options as ISOs in the written instrument
evidencing such Option. If the written instrument does not designate the Options
as ISOs, then the Option shall be a Nonstatutory Option.

    An Option may not be exercised for a fraction of a Share.

    An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the Stock
Option Agreement by the Optionee entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company.  Full payment may, as authorized by the Committee,
consist of any form of consideration and method of payment allowable under
Section 6(b)(ii) of this  Plan.  Upon the receipt of notice of exercise and full
----------------
payment for the Shares, the Shares shall be deemed to have been issued and the
Optionee shall be entitled to receive such Shares and shall be a shareholder
with respect to such Shares, and the Shares shall be considered fully paid and
nonassessable.  No adjustment will be made for a dividend or other right for
which the record date is prior to the date on which the stock certificate is
issued, except as provided in Section 9 of this Plan.
                              ---------

    Each exercise of an Option shall reduce, by an equal number, the total
number of Shares that may thereafter be purchased under such Option.

         (ii)    Termination of Status as an Employee or Consultant.  Except as
                 --------------------------------------------------
provided in Subsections 6(c)(iii) and 6(c)(iv) below, an Optionee holding an
            ----------------------    --------
Option who ceases to be an Employee,  a  Consultant or a director of the Company
may, but only until the earlier of the date (x) the Option held by the Optionee
expires, or (y) thirty (30) days after the date such Optionee ceases to be an
Employee, a Consultant or a director, exercise the Option to the extent that the
Optionee was entitled to exercise it on such date; provided, however, that in
the event the Optionee is an Employee and is terminated without cause (as
determined in the sole discretion of the Committee) then the thirty (30) day
period described in this sentence shall be automatically extended to ninety (90)
days (and in the case of a Nonstatutory Option, such period shall be
automatically extended to six (6) months), unless the Committee further extends
such period in its sole discretion.  To the extent that the Optionee was not
entitled to exercise an Option on such date, or if the Optionee does not
exercise it within the time specified herein, such Option shall terminate.  The
Committee shall have the authority to determine the date an Optionee ceases to
be an Employee, a Consultant or a director.

         (iii)   Permanent and Total Disability.  Notwithstanding the provisions
                 ------------------------------
of Section 6(c)(ii) above, in the event an Optionee is unable to continue to
   ----------------
perform Services for the Company or any of its Subsidiaries as a result of such
Optionee's Permanent and Total Disability (and, for ISOs, at the time such
Permanent and Total Disability begins, the Optionee was an Employee and had been
an Employee since the Date of Grant), such Optionee may exercise an Option in
whole or in part notwithstanding that such Option may not be fully exercisable,
but

                                       8
<PAGE>

only until the earlier of the date (x) the Option held by the Optionee expires,
or (y) twelve (12) months from the date of termination of Services due to such
Permanent and Total Disability. To the extent the Optionee is not entitled to
exercise an Option on such date or if the Optionee does not exercise it within
the time specified herein, such Option shall terminate.

         (iv)  Death of an Optionee.  Upon the death of an Optionee, any Option
               --------------------
held by an Optionee shall terminate and be of no further effect; provided,
however, notwithstanding the provisions of Section 6(c)(ii) above, in the event
                                           ----------------
an Optionee's death occurs during the term of an Option held by such Optionee
and, at the time of death, the Optionee was an Employee, Consultant or, director
(and, for ISOs, the Optionee had been an Employee since the Date of Grant), the
Option may be exercised in whole or in part notwithstanding that such Option may
not have been fully exercisable on the date of the Optionee's death, but only
until the earlier of the date (x) the Option held by the Optionee expires, or
(y) twelve (12) months from the date of the Optionee's death, by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance.  To the extent the Option is not entitled to be exercised on
such date or if the Option is not exercised within the time specified herein,
such Option shall terminate.

    (d)  Non-Transferability of Options.  Except as may be permitted by the
         ------------------------------
Committee in its sole discretion, any Option granted under this Plan may not be
sold, pledged, assigned, hypothecated, transferred or disposed of in any manner
other than by will or by the laws of descent and distribution or pursuant to a
qualified domestic relations order as defined by the Code or Title I of the
Employee Retirement Income Security Act, or the rules thereunder, and is not
assignable by operation of law or subject to execution, attachment or similar
process.  During the Optionee's lifetime, any Option granted under this Plan can
only be exercised by such Optionee.  Any attempted sale, pledge, assignment,
hypothecation or other transfer of the Option contrary to the provisions hereof
and the levy of any execution, attachment or similar process upon the Option
shall be null and void and without force or effect.  No transfer of the Option
by will or by the laws of descent and distribution shall be effective to bind
the Company unless the Company shall have been furnished written notice thereof
and an authenticated copy of the will and/or such other evidence as the
Committee may deem necessary to establish the validity of the transfer and the
acceptance by the transferee or transferees of the terms and conditions of the
Option.  The terms of any Option transferred by will or by the laws of descent
and distribution shall be binding upon the executors, administrators, heirs and
successors of Optionee.

    (e)  Time of Granting Options.  Any Option granted hereunder shall be deemed
         ------------------------
to be granted on the Date of Grant.  Written notice of the Committee's
determination to grant an Option to a Participant, evidenced by a Stock Option
Agreement, dated as of the Date of Grant, shall be given to such Participant
within a reasonable time after the Date of Grant.

    (f)  Modification, Extension and Renewal of Options. Within the limitations
         ----------------------------------------------
of this Plan, the Committee may modify, extend or renew outstanding Options or
may accept the cancellation of outstanding Options (to the extent not previously
exercised) for the granting of new Options in substitution therefor.  The
foregoing notwithstanding, no modification of an Option shall, without the
consent of the Optionee, alter or impair the Optionee's rights or obligations
under such Option; provided that the Committee may, in its sole discretion, and

                                       9
<PAGE>

without the consent of the Optionee or any other person, reduce the exercise
price of all or any part of any Option or accelerate the vesting of all or part
of any Option.

    (g) Restrictions on Transfer of Shares.  Any Shares issued upon exercise of
        ----------------------------------
an Option shall be subject to such rights of repurchase and other transfer
restrictions as the Committee may determine in its sole discretion.  Such
restrictions shall be set forth in the applicable Stock Option Agreement.

    (h) Special Limitation on ISOs.  To the extent that the aggregate Fair
        --------------------------
Market Value (determined on the Date of Grant) of the Shares with respect to
which ISOs are exercisable for the first time by an individual during any
calendar year under this Plan, and under all other plans maintained by the
Company, exceeds $100,000, such Options shall be treated as Nonstatutory
Options.

    (i) Leaves of Absence.  Leaves of absence approved by the Committee which
        -----------------
conform to the policies of the Company shall not be considered termination of
employment until the employer-employee relationship, as defined under the Code
or the regulations promulgated thereunder, ends or, if earlier, the leave of
absence period expires and the individual fails to return to active employment
with the Company.

    (j) Limitation on Grants of Plan Awards to Covered Employees.  The total
        --------------------------------------------------------
number of Shares for which Options may be granted and which may be awarded as
Restricted Stock to any Covered Employee during any calendar year period shall
not exceed twenty-five percent (25%) of the Plan Maximum in the aggregate.

    (k) Disqualifying Dispositions.  The Stock Option Agreement evidencing any
        --------------------------
ISO granted under this Plan shall provide that if the Optionee makes a
disposition, within the meaning of Section 425(c) of the Code and the
regulations promulgated thereunder, of any share or shares issued to him
pursuant to the exercise of the ISO within the two-year period commencing on the
day after the Date of Grant of such Option or within a one-year period
commencing on the day after the date of transfer of the share or shares to him
pursuant to the exercise of such Option, he shall, within ten days of such
disposition, notify the Company thereof and immediately deliver to the Company
any amount of federal income tax withholding required by law.

    (l) Withholding Taxes.  The Committee shall require an Optionee to pay to
        -----------------
the Company at the time of exercise of an Option the amount that the Company
deems necessary to satisfy its obligation to withhold federal, state or local
income or other taxes incurred by reason of the exercise.  Upon the exercise of
an Option requiring tax withholding, an Optionee may either pay such taxes in
cash or make a written election to have Shares withheld by the Company from the
shares otherwise to be received by the Optionee.  The acceptance of any such
election by an Optionee shall be at the sole discretion of the Committee.  In
addition, the Committee may require the Company to withhold Shares from the
Shares otherwise to be received by an Optionee upon exercise of an option.  The
number of Shares withheld pursuant to this paragraph shall have an aggregate
Fair Market Value on the date of exercise sufficient to satisfy the applicable
withholding taxes.

                                       10
<PAGE>

     (m) Return of Proceeds.
         ------------------

               (i)  The Committee, in its discretion, may include as a term of
any Optionee's stock option agreement a provision that, if within one year after
ceasing to be an Employee or Consultant (whether voluntarily or involuntarily),
an Optionee shall, directly or indirectly, engage in an activity that competes
with the business of the Company or a Subsidiary as conducted at the time the
Optionee ceased to be an Employee or Consultant (as determined by the Board of
Directors in its sole discretion and good faith) and such Optionee had exercised
Options within six months before or after the date the Optionee ceased to be an
Employee or Consultant, the Optionee shall be required to remit to the Company
in good funds within 5 business days of receipt of written demand therefore an
amount equal to the excess of (A) the Fair Market Value per share of Stock on
the date of exercise of such Option(s) multiplied by the number of shares with
respect to which the Options were exercised over (B) the aggregate option
exercise price for such number of shares of Stock (the "Proceeds").

               (ii) The Committee, in its discretion, may include as a term of
any Optionee's stock option agreement a provision requiring the remittance by an
Optionee to the Company in good funds within 5 business days of receipt of
written demand therefore of Proceeds by an Optionee that has exercised Options
within six months before or after the date the Optionee ceased to be an Employee
or Consultant (whether voluntarily or involuntarily). The Committee shall have
the authority in its discretion to include such other conditions and/or terms in
an Optionee's stock option agreement that it deems appropriate or desirable in
furtherance of the foregoing provisions.

     (n) Grants of Options to Non-Employee Directors.  Subject to the terms and
         -------------------------------------------
conditions of this Section 6(n), each Non-Employee Director of the Company
shall, subject to the terms of the Plan, be granted on his or her appointment to
the Board of Directors or on the approval of this Plan by the stockholders of
the Company, whichever occurs later, a grant of Options to purchase 100,000
Shares.  Unless otherwise provided in the applicable Stock Option Agreement,
each Option granted pursuant to this Section 6(n) shall become exercisable as to
one-twelfth of the Shares subject to Options at the end of each full calendar
quarter following the date of grant of the Options, beginning with the end of
the first full calendar quarter following the date of grant of the Option, and
would have an exercise price per share equal to the Fair Market Value of the
Stock on the date of grant; provided, however, that such Non-Employee Director
must be serving as a Non-Employee Director of the Company on the last day of
such quarter for such option to vest.

                                   SECTION 7
                               RESTRICTED STOCK
                               ----------------

     (a) Authority to Grant Restricted Stock.  The Committee shall have the
         -----------------------------------
authority to grant to Participants Shares that are subject to certain terms,
conditions and restrictions (the "Restricted Stock").  The Restricted Stock may
be granted by the Committee either separately or in combination with Options.
The terms, conditions and restrictions of the Restricted Stock shall be
determined from time to time by the Committee without limitation, except as
otherwise

                                       11
<PAGE>

provided in this Plan; provided, however, that each grant of Restricted Stock
shall require the Participant to remain an Employee of (or otherwise provide
Services to) the Company or any of its Subsidiaries for at least six (6) months
from the Date of Grant. The granting, vesting and issuing of the Restricted
Stock shall also be subject to the following provisions:

         (i)   Nature of Grant.  Restricted Stock shall be granted to
               ---------------
Participants for Services rendered and at no additional cost to Participant;
provided, however, that the value of the Services performed must, in the opinion
of the Committee, equal or exceed the par value of the Restricted Stock to be
granted to the Participant.

         (ii)  Restricted Stock Account.  The Company shall establish a
               ------------------------
restricted stock account (the "Restricted Stock Account") for each Participant
to whom Restricted Stock is granted, and such Restricted Stock shall be credited
to such account.  No certificates will be issued to the Participant with respect
to the Restricted Stock until the Vest Date as provided herein.  Every credit of
Restricted Stock under this Plan to a Restricted Stock Account shall be
considered "contingent" and unfunded until the Vest Date.  Such contingent
credits shall be considered bookkeeping entries only, notwithstanding the
"crediting" of "dividends" as provided herein.  Such accounts shall be subject
to the general claims of the Company's creditors.  The Participant's rights to
the Restricted Stock Account shall be no greater than that of a general creditor
of the Company.  Nothing contained herein shall be construed as creating a trust
or fiduciary relationship between the Participants and the Company, the Board of
Directors or the Committee.

         (iii) Restrictions.  The terms, conditions and restrictions of the
               ------------
Restricted Stock shall be determined by the Committee on the Date of Grant.  The
Restricted Stock may not be sold, assigned, transferred, redeemed, pledged or
otherwise encumbered during the period in which the terms, conditions and
restrictions apply (the "Restriction Period").  More than one grant of
Restricted Stock may be outstanding at any one time, and the Restriction Periods
may be of different lengths.  Receipt of the Restricted Stock is conditioned
upon satisfactory compliance with the terms, conditions and restrictions of this
Plan and those imposed by the Committee, which may include the achievement of
any Performance Goals established by the Committee.

         (iv)  Restricted Stock Criteria.  At the time of each grant of
               -------------------------
Restricted Stock, the Committee in its sole discretion may establish certain
criteria to determine the times at which restrictions placed on Restricted Stock
shall lapse (i.e., the termination of the Restriction Period), which criteria
may include without limitation performance measures and targets (which may
include any Performance Goals established by the Committee) and/or holding
period requirements (the "Restricted Stock Criteria").  The Committee may
establish a corresponding relationship between the Restricted Stock Criteria and
(x) the number of Shares of Restricted Stock that may be earned, and (y) the
extent to which the terms, conditions and restrictions on the Restricted Stock
shall lapse.  Restricted Stock Criteria may vary among grants of Restricted
Stock; provided, however, that once the Restricted Stock Criteria are
established for a grant of Restricted Stock, the Restricted Stock Criteria shall
not be modified with respect to such grant.

         (v)   Vesting.  On the date the Restriction Period terminates, the
               -------
Restricted Stock shall vest in the Participant (the "Vest Date"), who may then
require the Company to issue

                                       12
<PAGE>

certificates evidencing the Restricted Stock credited to the Restricted Stock
Account of such Participant.

         (vi)    Dividends.  The Committee may provide from time to time that
                 ---------
amounts equivalent to dividends shall be payable with respect to the Restricted
Stock held in the Restricted Stock Account of a Participant.  Such amounts shall
be credited to the Restricted Stock Account and shall be payable to the
Participant on the Vest Date.

         (vii)   Termination of Services.  If a Participant (x) with the consent
                 -----------------------
of the Committee, ceases to be an Employee of, or otherwise ceases to provide
Services to, the Company or any of its Subsidiaries, or (y) dies or suffers from
Permanent and Total Disability, the vesting or forfeiture (including without
limitation the terms, conditions and restrictions) of any grant under this
Section 7 shall be determined by the Committee in its sole discretion, subject
---------
to any limitations or terms of this Plan.  If the Participant ceases to be an
Employee of, or otherwise ceases to provide Services to, the Company or any of
its Subsidiaries for any other reason, all grants of Restricted Stock under this
Plan shall be forfeited (subject to the terms of this Plan).

         (viii)  Certificates.  The Committee may legend the certificates
                 ------------
representing the Restricted Stock to give appropriate notice of the applicable
terms, conditions and restrictions thereof, as well as any applicable
restrictions under applicable Federal or state securities laws, and may deposit
such certificates with the Secretary of the Company pending vesting of the
Restricted Stock.

    (b)  Deferral of Payments.
         --------------------

         The Committee may establish procedures by which a Participant may elect
to defer the transfer of Restricted Stock to the Participant.  The Committee
shall determine the terms and conditions of such deferral in its sole
discretion.

                                   SECTION 8
                              ISSUANCE OF SHARES
                              ------------------

    As a condition to the transfer of any Shares issued under this Plan, the
Company may require an opinion of counsel, satisfactory to the Company, to the
effect that such transfer will not be in violation of the Securities Act of
1933, as amended (the "Securities Act"), or any other applicable securities
laws, rules or regulations, or that such transfer has been registered under
federal and all applicable state securities laws.  The Company may refrain from
delivering or transferring Shares issued under this Plan until:  (1) the
Committee has determined that the Participant has tendered to the Company any
and all applicable federal, state or local tax owed by the Participant as the
result of the receipt of a Plan Award, the exercise of an Option or the
disposition of any Shares issued under this Plan, in the event that the Company
reasonably determines that it might have a legal liability to satisfy such tax,
(2) the Company has determined that all applicable listing requirements of any
stock exchange or quotation system on which the Shares are listed have been
satisfied, and (3) the Company has determined that any other applicable
provision of state or federal law, including without limitation applicable state

                                       13
<PAGE>

securities laws, has been satisfied.  The Company shall not be liable to any
person or entity for damages due to any delay in the delivery or issuance of any
stock certificate evidencing any Shares for any reason whatsoever.

                                   SECTION 9
             CAPITALIZATION ADJUSTMENTS; MERGER; CHANGE IN CONTROL
             -----------------------------------------------------

    (a) Adjustments Upon Changes in Capitalization.  Subject to any required
        ------------------------------------------
action by the stockholders of the Company, the number of Shares covered by each
outstanding Option, the aggregate number of Shares that have been authorized for
issuance under this Plan and the number of Shares of Restricted Stock credited
to any Restricted Stock Account of a Participant (as well as the Exercise Price
covered by any outstanding Option), shall be proportionately adjusted for any
increase or decrease in the number of issued Shares resulting from a stock
split, payment of a stock dividend with respect to the Stock or any other
increase or decrease in the number of issued Shares effected without receipt of
consideration by the Company.  Such adjustment shall be made by the Committee in
its sole discretion, which adjustment shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class shall affect, and no adjustment by reason thereof shall be
made with respect to, the number or price of Shares subject to an Option.

    (b) Dissolution, Liquidation, Sale of Assets or Merger.  In the event of the
        --------------------------------------------------
dissolution or liquidation of the Company, other than pursuant to a
Reorganization (hereinafter defined), any Option granted under the Plan shall
terminate as of a date to be fixed by the Committee, provided that not less than
30 days written notice of the date so fixed shall be given to each Optionee and
each such Optionee shall have the right during such period to exercise his
Options as to all or any part of the Shares covered thereby including Shares as
to which such Options would not otherwise be exercisable by reason of an
insufficient lapse of time.

    In the event of a Reorganization, then, as a condition of such
Reorganization, lawful and fair provision shall be made whereby the Option
holders shall thereafter have the right to purchase and receive, upon the basis
and upon the terms and conditions specified in the Plan and the stock option
agreements and in lieu of the shares of Stock of the Company immediately
theretofore purchasable and receivable upon the exercise of the rights
represented thereby, such shares of stock, securities, or assets as may be
issued or payable with respect to or in exchange for the number of outstanding
shares of such Stock equal to the number of shares of such stock immediately
theretofore purchasable and receivable upon the exercise of the rights
represented by such Options, had such Reorganization not taken place, and in
such event appropriate provision shall be made with respect to the rights and
interests of the Option holders to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the exercise price
and of the number of shares purchasable upon the exercise of such Options) shall
thereafter be applicable, as nearly as may be in relation to any share of stock,
securities, or assets thereafter deliverable upon the exercise hereof.

    The term "Reorganization" as used in this Subsection 9(b) shall mean any
                                              ---------------
merger, consolidation, sale of all or substantially all of the assets of the
Company, sale, pursuant to an agreement with the Company, of securities of the
Company pursuant to which the Company is or

                                       14
<PAGE>

becomes a wholly-owned subsidiary of another company after the effective date of
the Reorganization, or other similar event.

     (c) Limitation on Rights of Optionee.  Except as expressly provided in this
         --------------------------------
Section 9, no Optionee shall have any rights by reason of any payment of any
stock dividend, stock split or reverse stock split or any other increase or
decrease in the number of shares of stock of any class, or by reason of any
reorganization, consolidation, dissolution, liquidation, merger, exchange,
split-up or reverse split-up, or spin-off of assets or stock of another
corporation.  Any issuance by the Company of Shares, Options or securities
convertible into Shares or Options shall not affect, and no adjustment by reason
thereof shall be made with respect to, the number or Exercise Price of the
Shares for which an Option is exercisable.  Notwithstanding the foregoing, if
the Company shall enter into a transaction affecting the Company's capital stock
or distributions to the holders of its capital stock for which a revision in the
terms of each Option is not required pursuant to this Section 9, the Committee
shall revise the terms of each Option in a manner the Committee deems fair and
reasonable in its sole discretion given the transaction involved.  If necessary
or appropriate in connection with such transaction, the Committee may declare
that any Option shall terminate as of a date fixed by the Committee and give
each Optionee the right to exercise his or her Option in whole or in part,
including exercise as to shares of Stock to which the Option would not otherwise
be exercisable.

     (d) Change in Control.  Subject to Section 9(b), in the event there occurs
         -----------------
a Change of Control, (i) the Optionees shall have the right to exercise from and
after the date of the Change in Control the Option held by such Optionee in
whole or in part notwithstanding that such Option may not be fully exercisable,
and (ii) any and all restrictions on any Restricted Stock credited to a
Restricted Stock Account shall lapse and such stock shall immediately vest in
the Participants notwithstanding that the Restricted Stock held in such account
was unvested.

     (e) Stock Dividend; Distribution of Assets.  In the event of a stock
         --------------------------------------
dividend or other distribution of assets by the Company to the holders of the
Stock which is not covered by any provision of this Section 9, the Option
holders shall be entitled thereafter to receive upon exercise of the Option the
kind and amount of such distribution, whether cash, shares of stock or other
securities or assets, which the Option holder would have been entitled to
receive after the occurrence of such event had this Option been exercised
immediately prior to such event.

     (f) No Restriction on Rights of Company.  The grant of an Option shall not
         -----------------------------------
affect or restrict in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations, or changes of its capital or
business structure, or to merge or consolidate, or to dissolve, liquidate, sell,
or transfer all or any part of its business or assets.

                                  SECTION 10
                             NO EMPLOYMENT RIGHTS
                             --------------------

     No provision of this Plan, under any Stock Option Agreement or under any
grant of Restricted Stock shall be construed to give any Participant any right
to remain an Employee of, or provide Services to, the Company or any of its
Subsidiaries or to affect the right of the Company to terminate any
Participant's service at any time, with or without cause.

        -------------------------
discretion may terminate this Plan at any time.  The Board of Directors may

advisable; provided, that any change in the aggregate number of Shares that may
           --------
be issued under this Plan, other than in connection with an adjustment under
Section 9 of this Plan, shall require approval of the holders of a majority of
---------
the outstanding Shares entitled to vote.

    (c) Effect of Termination.  In the event this Plan is terminated, no Shares
        ---------------------
shall be issued under this Plan, except upon exercise of an Option granted prior

credited to a Restricted Stock Account.  The termination of this Plan, or any
amendment thereof, shall not affect any Shares previously issued to a
Participant, any Option previously granted under this Plan or any Restricted
Stock previously credited to a Restricted Stock Account.

unless otherwise provided by the Plan, shall have no rights as a stockholder
with respect thereto unless and until shares of Stock are issued to him.

    (b) Indemnification.  No member of the Board of Directors or the Committee,

Plan (including without limitation determinations of the persons to receive
awards, the form, amount and timing of such awards, the terms and provisions of
such awards and the agreements evidencing same, and the establishment of values

Section 422 of the Code with respect to awards subject to or governed by Section
162(m) or Section 422 of the Code, then such terms or provisions shall be deemed
inoperative to the extent they so conflict with the requirements of Section
162(m) or Section 422 of the Code.  With respect to an Incentive Stock Option,
if this Plan does not contain any provisions required to be included herein

    (h) No Strict Construction.  No rule of strict construction shall be applied

any successor to the Company, whether by way of merger, consolidation, purchase,
or otherwise.

    (j) Plan Provisions Control.  The terms of the Plan govern all awards
