RE: Phase One Galactica Discontinuous Strategy Engagement Letter

Dear Brian:

Ascent Partners, Inc will provide consulting services to ARI divided into
two approximately equal tranches of $12,500 each, separated by a GO/NO-GO
Board discussion at the July 24 meeting. Ascent will perform the first
part starting right away; the second if and only if ARI wishes to go to the
next step after discussion at the Board meeting. ARI will pre-pay each
tranche.

Part One of the engagement is primarily focused on the
“inorganic/discontinuous” strategy. Output equals a Board presentation
that outlines how and why ARI would propose to use Corporate Development to
add components to ARI’s solution set within the context of a broader
strategy. Additional deliverables and process are described in the attached
document entitled “Project Galactica—Discontinuous Strategy”.

Should phase two of the project receive approval to proceed, Ascent would
then work closely with the ARI corporate development function to identify
and yield the target companies that would advance the
inorganic/discontinuous strategy.

ARI agrees to cover any pre-approved out-of-pocket costs, if they are
needed, associated with the project such as travel, purchased research,
select PowerPoint production and sophisticated spreadsheet modeling.

If you are in agreement with these terms please sign below. I am looking
forward to an interesting engagement as we endeavor to discover an
actionable and successful discontinuous value proposition(s) for ARI that
grows revenue and contributes to the Company’s value.

Sincerely,

Ted Feierstein, Managing Director

Agreed to and confirmed this
25th day of June, 2003.

         SECTION 1.2. COMPLIANCE CERTIFICATES AND OPINIONS. Upon any application
or request by the Company to the Trustee to take any action under any provision
of this Indenture, the Company shall furnish to the Trustee an Officer's
Certificate stating that all conditions precedent, if any, provided for in this
Indenture relating to the proposed action have been complied with and an Opinion
of Counsel stating that in the opinion of such counsel all such conditions
precedent, if any, have been complied with, except that in the case of any
application or request as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than pursuant to
Sections 2.3 and 9.7) shall include:

                           (1)      a statement that the individual signing such
                                    certificate or opinion has read such
                                    condition or covenant and any definitions in
                                    this Indenture that are used in such
                                    certificate or opinion;

                                       8
<PAGE>

                           (2)      a brief statement as to the nature and scope
                                    of the examination or investigation upon
                                    which the statements or opinions contained
                                    in such certificate or opinion are based;

                           (3)      a statement that, in the opinion of each
                                    such individual, he has made such
                                    examination or investigation as is necessary
                                    to enable him to express an informed opinion
                                    as to whether or not such condition or
                                    covenant has been complied with; and

                           (4)      a statement as to whether, in the opinion of
                                    such individual, such condition or covenant
                                    has been complied with.

         SECTION 1.3. 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 Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
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
Company stating that the information with respect to such factual matters is in
the possession of the Company, unless such counsel knows that the certificate or
opinion or representations as to such matters are erroneous.

         Any certificate or opinion of an officer of the Company or of counsel
may be based, insofar as it relates to accounting matters, upon a certificate or
opinion of or representations by an accountant or firm of accountants in the
employ of the Company, unless such officer or counsel, as the case may be, knows
that the certificate or opinions or representations as to such accounting
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.

         SECTION 1.4. ACTS OF HOLDERS.

                  (a)      Any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes

                                       9
<PAGE>

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 conclusive in
favor of the Trustee and the Company, if made in the manner provided in this
Section.

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

                  (c)      The ownership of Bearer Securities may be proved by
the production of such Bearer Securities or by a certificate executed by any
trust company, bank, banker or other depository, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depository, or
exhibited to it, the Bearer Securities therein described; or such facts may be
proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (i) another such certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is produced,
(ii) such Bearer Security is produced to the Trustee by some other Person, (iii)
such Bearer Security is surrendered in exchange for a Registered Security or
(iv) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

                  (d)      The ownership of Registered Securities shall be
proved by the Register (as defined in Section 3.5 below).

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

                  (f)      If the Company shall solicit from the Holders of any
series any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, fix in advance a record date for the
determination of Holders of such series entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of such series of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities of such series have authorized or agreed or

                                       10
<PAGE>

consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities of such
series shall be computed as of such record date; provided that no such
authorization, agreement or consent by the Holders on such record date shall be
deemed effective unless taken on or prior to the applicable Expiration Date (as
defined below) by Holders of the requisite amount of Outstanding Securities of
such series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of Notes in the manner set forth in Section 1.6.

         With respect to any record date set pursuant to this Section 1.4, the
Company may designate any date 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 Trustee, and to each Holder of Securities of the applicable
series in the manner set forth in Section 1.6 on or prior to the existing
Expiration Date. If an Expiration Date is not designated with respect to any
record date pursuant to this Section, the Company shall be deemed to have
initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

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

                  (h)      The Company and the Trustee may make reasonable rules
for action by or at a meeting of Holders.

         SECTION 1.5. NOTICES, ETC., TO TRUSTEE AND COMPANY. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

                           (1)      the Trustee by any Holder or by the Company
                                    shall be sufficient for every purpose
                                    hereunder if made, given, furnished or filed
                                    in writing to or with the Trustee to the
                                    attention of its Corporate Trust Office, or

                           (2)      the Company by the Trustee or by any Holder
                                    shall be sufficient for every purpose
                                    hereunder (unless otherwise herein expressly
                                    provided) if in writing and mailed,
                                    first-class postage prepaid, to the Company
                                    addressed to it at Superconductor
                                    Technologies Inc.,

                                       11
<PAGE>

                                    460 Ward Drive, Santa Barbara, CA 93111 or
                                    at any other address previously furnished in
                                    writing to the Trustee by the Company.

         SECTION 1.6. NOTICE TO HOLDERS; WAIVER. Where this Indenture provides
for notice to Holders of any event, (i) if any of the Securities affected by
such event are Registered Securities, such notice to the Holders thereof shall
be sufficiently given (unless otherwise herein or in the terms of such
Securities expressly provided) if in writing and mailed, first-class postage
prepaid, to each such Holder affected by such event, at his address as it
appears in the Register, within the time prescribed for the giving of such
notice and, (ii) if any of the Securities affected by such event are Bearer
Securities, notice to the Holders thereof shall be sufficiently given (unless
otherwise herein or in the terms of such Bearer Securities expressly provided)
if published once in an Authorized Newspaper in New York, New York, and in such
other city or cities, if any, as may be specified as contemplated by Section
3.1.

         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 of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. In any case where notice
is given to Holders by publication, neither the failure to publish such notice,
nor any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein. Any
notice mailed to a Holder in the manner herein prescribed shall be conclusively
deemed to have been received by such Holder, whether or not such Holder actually
receives such notice.

         If by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice as provided above,
then such notification as shall be made with the approval of the Trustee (such
approval not to be unreasonably withheld) shall constitute a sufficient
notification for every purpose hereunder. If it is impossible or, in the opinion
of the Trustee, impracticable to give any notice by publication in the manner
herein required, then such publication in lieu thereof as shall be made with the
approval of the Trustee shall constitute a sufficient publication of such
notice.

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

         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 equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         SECTION 1.7. HEADINGS AND TABLE OF CONTENTS. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

                                       12
<PAGE>

         SECTION 1.8. SUCCESSOR AND ASSIGNS. All covenants and agreements in
this Indenture by the Company shall bind its successor and assigns, whether so
expressed or not.

         Any act or proceeding that is required or permitted by any provision of
this Indenture and that is authorized or required to be done or performed by any
board, committee or officer of the Company shall and may be done and performed
with like force and effect by the like board, committee or officer of any
corporation that shall at the time be the successor or assign of the Company.

         SECTION 1.9. SEPARABILITY. In case any provision of this Indenture or
the Securities shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

         SECTION 1.10. BENEFITS OF INDENTURE. Nothing in this Indenture or in
the Securities, expressed or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, any Agent and the Holders, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

         SECTION 1.11. GOVERNING LAW. UNLESS OTHERWISE PROVIDED WITH RESPECT TO
ANY SECURITIES OF ANY SERIES PURSUANT TO SECTION 3.1, THIS INDENTURE, THE
SECURITIES AND ANY COUPONS APPERTAINING THERETO SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING ALL
MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE. This Indenture is subject to
the Trust Indenture Act and if any provision hereof limits, qualifies or
conflicts with a provision included in this Indenture which is required by the
Trust Indenture Act, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified, or to be excluded, as the case may be,
whether or not such provision of this Indenture refers expressly to such
provision of the Trust Indenture Act.

         SECTION 1.12. LEGAL HOLIDAYS. Unless otherwise provided with respect to
any Security or Securities pursuant to Section 3.1, in any case where any
Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity or other payment date of any Security shall not be a
Business Day at any Place of Payment, then, notwithstanding any other provision
of this Indenture or any Security or coupon, payment of principal, premium, if
any or interest or other payments need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on such date; provided that no
interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity or other payment date, as the case may be.

         SECTION 1.13. NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, agent, member, manager, trustee or stockholder, as
such, of the Company or any successor Person shall have any liability for any
obligations of the Company or any successor Person, either directly or through
the Company or any successor Person, under the Securities or this Indenture or
for any claim based on, in respect of or by reason of such

                                       13
<PAGE>

obligations or their creation, whether by virtue of any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise. By accepting a Security, each Holder
agrees to the provisions of this Section 1.13 and waives and releases all such
liability. Such waiver and release shall be part of the consideration for the
issue of the Securities.

                                   ARTICLE II

                                 SECURITY FORMS

         SECTION 2.1. FORMS GENERALLY. The Securities of each series and the
coupons, if any, to be attached thereto shall be in substantially such form as
shall be established by or pursuant to a Board Resolution or in one or more
indentures supplemental hereto, in each case with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by
this Indenture, and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as the Company
may deem appropriate or as may be required to comply with any applicable law,
rule or regulation or with the rules or usage of any securities exchange or
Depository therefor or as may, consistently herewith, be determined by the
officers executing such Securities and coupons, if any, as evidenced by their
execution of the Securities and coupons, if any. If temporary Securities of any
series are issued as permitted by Section 3.4, the form thereof also shall be
established as provided in the preceding sentence. If the forms of Securities
and coupons, if any, of any series are established by, or by action taken
pursuant to, a Board Resolution, a copy of the Board Resolution, and, if such
Board Resolution delegates a particular action to another Person, an appropriate
record of any such action taken pursuant thereto, including a copy of the
approved form of Securities or coupons, if any, shall be certified by the
Corporate Secretary or an Assistant Secretary of the Company and delivered to
the Trustee at or prior to the delivery of the Company Order contemplated by
Section 3.3 for the authentication and delivery of such Securities.

         Unless otherwise specified as contemplated by Section 3.1, Bearer
Securities shall have interest coupons attached.

         The definitive Securities and coupons, if any, shall be typeset,
printed, lithographed or engraved on steel engraved borders or may be produced
in any other manner or medium, all as determined by the officers executing such
Securities and coupons, if any, as evidenced by their execution of such
Securities and coupons, if any.

         SECTION 2.2. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION. Subject
to Section 6.13 (as applicable to any Authenticating Agent), the Trustee's
certificate of authentication shall be in substantially the following form:

         This is one of the [Securities] [of the series designated herein and]
referred to in the within-mentioned Indenture.

                                          __________________________, as Trustee
Dated:                                    By: Authorized Signatory

                                       14
<PAGE>

         SECTION 2.3. SECURITIES IN GLOBAL FORM. If Securities of or within a
series are issuable in whole or in part in global form, any such Security may
provide that it shall represent the aggregate or specified amount of Outstanding
Securities from time to time endorsed thereon and may also provide that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be reduced or increased to reflect exchanges. Any endorsement of a Security
in global form to reflect the amount, or any increase or decrease in the amount,
or changes in the rights of Holders, of Outstanding Securities represented
thereby, shall be made in such manner and by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee
pursuant to Section 3.3 or 3.4. Subject to the provisions of Section 3.3 and, if
applicable, Section 3.4, the Trustee shall deliver and redeliver any security in
permanent global form in the manner and upon instructions given by the Person or
Persons specified therein or in the applicable Company Order. Any instructions
by the Company with respect to endorsement or delivery or redelivery of a
Security in global form shall be in writing but need not comply with Section 1.2
hereof and need not be accompanied by an Opinion of Counsel.

         The provisions of the last paragraph of Section 3.3 shall apply to any
Security in global form if such Security was never issued and sold by the
Company and the Company delivers to the Trustee the Security in global form
together with written instructions (which need not comply with Section 1.2 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last paragraph of Section 3.3.

         Notwithstanding the provisions of Section 2.1 and 3.7, unless otherwise
specified as contemplated by Section 3.1, payment of principal of, premium, if
any, and interest on any Security in permanent global form shall be made to the
Person or Persons specified therein.

         SECTION 2.4. FORM OF LEGEND FOR SECURITIES IN GLOBAL FORM. Unless
otherwise provided with respect to any Securities of any series pursuant to
Section 3.1 or required by the Depository, any Security of such series in global
form authenticated and delivered hereunder shall bear a legend in substantially
the following form:

                  This Security is in global form within the meaning of the
                  Indenture hereinafter referred to and is registered in the
                  name of a Depository or a nominee of a Depository. Unless and
                  until it is exchanged in whole or in part for Securities in
                  certificated form, this Security may not be transferred except
                  as a whole by the Depository to a nominee of the Depository or
                  by a nominee of the Depository to the Depository or another
                  nominee of the Depository or by the Depository or any such
                  nominee to a successor Depository or a nominee of such

established by or pursuant to one or more Board Resolutions as permitted by
Sections 2.1 and 3.1, in authenticating such Securities and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to section 315(a) through

                                    appertaining thereto, when authenticated and

                                    subject to any conditions specified in such
                                    Opinion of Counsel, will constitute legal,

                                    of Counsel, including in the case of any
                                    Securities denominated in a Foreign
                                    Currency, (A) requirements that a claim with
                                    respect to any Securities denominated other
                                    than in Dollars (or a foreign currency or
                                    foreign currency unit judgment in respect of
                                    such claim) be converted into Dollars at a
                                    rate of exchange prevailing on a date
                                    determined pursuant to applicable law or (B)
                                    governmental authority to limit, delay or
                                    prohibit the making of payments in foreign
                                    currency or currency units or payments
                                    outside the United States.

         Such Opinion of Counsel need express no opinion as to the
enforceability of Section 6.8 or as to whether a court in the United States
would render a money judgment in a currency other

                                       22

than that of the United States. Such counsel may rely on opinions of other
counsel (copies of which shall be delivered to the Trustee), and, to the extent
such opinion involves factual matters, such counsel may rely upon certificates
of officers of the Company and certificates of public officials.

         Notwithstanding that such form or terms have been so established, the
Trustee shall have the right to decline to authenticate such Securities if, in
the written opinion of counsel to the Trustee (which counsel may be an employee
of the Trustee), such action may not lawfully be taken or if the Trustee in good
faith by its board of directors or trustees, executive committee or a trust
committee of directors, trustees or vice presidents shall determine that such
action would expose the Trustee to personal liability.

         Notwithstanding the provisions of Section 3.1 and of the two preceding
paragraphs, if all of the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the Company Order and Opinion of Counsel
otherwise required pursuant to the two preceding paragraphs in connection with
the authentication of each Security of such series if such documents, with
appropriate modifications to cover such future issuances, 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 Company of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

         If the Company shall establish pursuant to Section 3.1 that the
Securities of a series are to be issued in whole or in part in global form,
then, unless otherwise provided with respect to such Securities pursuant to
Section 3.1, the Company shall execute and the Trustee shall, in accordance with
this Section and the Company Order with respect to such series, authenticate and
deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered, if a Registered Security,
in the name of the Depository for such Security or Securities in global form or
the nominee of such Depository, (iii) shall be delivered by the Trustee to such
Depository or pursuant to such Depository's instruction and (iv) shall bear the
legend set forth in Section 2.4.

         Unless otherwise established pursuant to Section 3.1, each Depository
designated pursuant to Section 3.1 for a Registered Security in global form
must, at the time of its designation and at all times while it serves as
Depository, be a clearing agency registered under the Securities Exchange Act of
1934 and any other applicable statute or regulation. Neither the Company nor the
Trustee shall have any responsibility to determine if the Depository is so
registered.

                                       23
<PAGE>

         Each Depository shall enter into an agreement with the Company and the
Trustee, as agent, governing the respective duties and rights of such
Depository, the Company and the Trustee, as agent, with regard to Securities
issued in global form.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 3.1.

         No Security or coupon appertaining thereto shall be entitled to any
benefits under this Indenture or be valid or obligatory for any purpose until
authenticated by the manual signature of one of the authorized signatories of
the Trustee or an Authenticating Agent and no coupon shall be valid until the
Security to which it appertains has been so authenticated. Such signature upon
any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered under this Indenture and is
entitled to the benefits of this Indenture. Except as permitted by Section 3.6
or 3.7, the Trustee shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
cancelled.

         Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.9 together with a written statement (which need not comply
with Section 1.2 and need not be accompanied by an Opinion of Counsel) stating
that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall not be entitled to the benefits
of this Indenture.

         SECTION 3.4. TEMPORARY SECURITIES. Pending the preparation of
definitive Securities of any series, the Company may execute and, upon Company
Order, the Trustee shall authenticate and deliver temporary Securities of such
series which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor and form,
with or without coupons, of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities and coupons, if
any. In the case of Securities of any series, all or a portion of such temporary
Securities may be in global form.

         Except in the case of temporary Securities in global form, each of
which shall be exchanged in accordance with the provisions thereof, if temporary
Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company pursuant to Section 9.2 in a Place of Payment for such series,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series (accompanied by any unmatured coupons
appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor; provided, however, that no definitive Bearer Security shall be delivered
in exchange for a temporary

                                       24
<PAGE>

Registered Security; and provided further that no definitive Bearer Security
shall be delivered in exchange for a temporary Bearer Security unless the
Trustee shall have received from the person entitled to receive the definitive
Bearer Security a certificate substantially in the form approved in or pursuant
to the Board Resolutions relating thereto and such delivery shall occur only
outside the United States. Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series except as otherwise specified
as contemplated by Section 3.1.

         SECTION 3.5. REGISTRATION, TRANSFER AND EXCHANGE. The Company shall
cause to be kept at the Corporate Trust Office of the Trustee or in any office
or agency to be maintained by the Company in accordance with Section 9.2 in a
Place of Payment or in such other place or medium as may be specified pursuant
to Section 3.1 a register for each series of Securities (the registers
maintained in such office or in any such office or agency of the Company in a
Place of Payment being herein sometimes referred to collectively as the
"Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Registered
Securities and the registration of transfers of Registered Securities. The
Register shall be in written form or any other form capable of being converted
into written form within a reasonable time. Unless otherwise provided as
contemplated by Section 3.1, the Trustee is hereby appointed "Registrar" for the
purpose of registering Registered Securities and transfers of Registered
Securities, and for the purpose of maintaining the Register in respect thereof,
as herein provided.

         Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency maintained pursuant to Section 9.2 in a
Place of Payment for that series, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Registered Securities of the same series, of any
authorized denominations and of a like aggregate principal amount.

         Unless otherwise provided as contemplated by Section 3.1, Bearer
Securities (except for any temporary global Bearer Securities) or any coupons
appertaining thereto (except for coupons attached to any temporary global Bearer
Security) shall be transferable by delivery.

         Unless otherwise provided as contemplated by Section 3.1, at the option
of the Holder, Registered Securities of any series (except a Registered Security
in global form) may be exchanged for other Registered Securities of the same
series, of any authorized denominations and of a like aggregate principal amount
containing identical terms and provisions, upon surrender of the Registered
Securities to be exchanged at such office or agency. Whenever any Registered
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Registered Securities which the
Holder making the exchange is entitled to receive. Unless otherwise specified as
contemplated by Section 3.1, Bearer Securities may not be issued in exchange for
Registered Securities.

         Unless otherwise specified as contemplated by Section 3.1, at the
option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations and of like tenor
and aggregate

                                       25
<PAGE>

principal amount, upon surrender of the Bearer Securities to be exchanged at any
such office or agency, with all unmatured coupons and all matured coupons in
default thereto appertaining. If the Holder of a Bearer Security is unable to
produce any such unmatured coupon or coupons or matured coupon or coupons in
default, such exchange may be effected if the Bearer Securities are accompanied
by payment in funds acceptable to the Company and the Trustee in an amount equal
to the face amount of such missing coupon or coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to any Paying Agent any such missing coupon in respect of which
such a payment shall have been made, such Holder shall be entitled to receive
the amount of such payment; provided, however, that, except as otherwise
provided in Section 9.2, interest represented by coupons shall be payable only
upon presentation and surrender of those coupons at an office or agency located
outside the United States. Notwithstanding the foregoing, in case any Bearer
Security of any series is surrendered at any such office or agency in exchange
for a Registered Security of the same series after the close of business at such
office or agency on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such office or
agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such coupon
is so surrendered with such Bearer Security, such coupon shall be returned to
the person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such coupon, when due in accordance with the provisions of this
Indenture.

         Unless otherwise specified pursuant to Section 3.1 with respect to a
series of Securities or as otherwise provided below in this Section 3.5, owners
of beneficial interests in Securities of such series represented by a Security
issued in global form will not be entitled to have Securities of such series
registered in their names, will not receive or be entitled to receive physical
delivery of Securities of such series in certificated form and will not be
considered the Holders or owners thereof for any purposes hereunder.
Notwithstanding any other provision of this Section, unless and until it is
exchanged in whole or in part for Securities in certificated form in the
circumstances described below, a Security in global form representing all or a
portion of the Securities of a series may not be transferred or exchanged except
as a whole by the Depository for such series to a nominee of such Depository or
by a nominee of such Depository to such Depository or another nominee of such
Depository or by such Depository or any such nominee to a successor Depository
for such series or a nominee of such successor Depository.

         If at any time the Depository for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depository for the
Securities of such series or if at any time the Depository for the Securities of
such series notifies the Company that it shall no longer be eligible under
Section 3.3, the Company shall appoint a successor Depository with respect to
the Securities of such series. Unless otherwise provided as contemplated by
Section 3.1, if a successor Depository for the Securities of such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such ineligibility, the

                                       26
<PAGE>

Company's election pursuant to Section 3.1(b) (26) shall no longer be effective
with respect to the Securities of such series and the Company shall execute, and
the Trustee, upon receipt of a Company Order for the authentication and delivery
of certificated Securities of such series of like tenor, shall authenticate and
deliver, Securities of such series of like tenor in certificated form, in
authorized denominations and in an aggregate principal amount equal to the
principal amount of the Security or Securities of such series of like tenor in
global form in exchange for such Security or Securities in global form.

         The Company may at any time in its sole discretion determine that
Securities of a series issued in global form shall no longer be represented by
such a Security or Securities in global form. In such event the Company shall
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

         If specified by the Company pursuant to Section 3.1 with respect to a
series of Securities, the Depository for such series may surrender a Security in
global form of such series in exchange in whole or in part for Securities of
such series in certificated form on such terms as are acceptable to the Company
and such Depository. Thereupon, the Company shall execute, and the Trustee shall
authenticate and deliver, without service charge,

                           (i)      to each Person specified by such Depository
                                    a new certificated Security or Securities of
                                    the same series of like tenor, of any
                                    authorized denomination as requested by such
                                    Person in aggregate principal amount equal
                                    to and in exchange for such Person's
                                    beneficial interest in the Security in
                                    global form; and

                           (ii)     to such Depository a new Security in global
                                    form of like tenor in a denomination equal
                                    to the difference, if any, between the
                                    principal amount of the surrendered Security
                                    in global form and the aggregate principal
                                    amount of certificated Securities delivered
                                    to Holders thereof.

                           (iii)    Upon the exchange of a Security in global
                                    form for Securities in certificated form,
                                    such Security in global form shall be
                                    cancelled by the Trustee. Unless expressly
                                    provided with respect to the Securities of
                                    any series that such Security may be
                                    exchanged for Bearer Securities, Securities
                                    in certificated form issued in exchange for
                                    a Security in global form pursuant to this
                                    Section shall be registered in such names
                                    and in such authorized denominations as the
                                    Depository for such Security in global form,
                                    pursuant to instructions from its direct or
                                    indirect participants or otherwise, shall
                                    instruct the Trustee. The

                                       27
<PAGE>

                                    Trustee shall deliver such Securities to the
                                    Persons in whose names such Securities are
                                    so registered.

         Whenever any Securities are surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

         All Securities issued upon any registration of transfer or upon any
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

         Every Registered Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company, the Registrar or
the Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company, the Registrar and the Trustee duly
executed by the Holder thereof or his attorney duly authorized in writing.

         Unless otherwise provided as contemplated by Section 3.1, no service
charge shall be made for any registration of transfer or for any exchange of
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any
registration or transfer or exchange of Securities, other than exchanges
pursuant to Section 3.4 or 10.7 not involving any transfer.

         Unless otherwise provided as contemplated by Section 3.1, none of the
Company, the Registrar or the Trustee shall be required (i) to issue, register
the transfer of, or exchange any Securities for a period beginning at the
opening of 15 Business Days before any selection for redemption of Securities of
like tenor and of the series of which such Security is a part and ending at the
close of business on the earliest date on which the relevant notice of
redemption is deemed to have been given to all Holders of Securities of like
tenor and of such series to be redeemed; (ii) to register the transfer of or
exchange any Registered Security so selected for redemption, in whole or in
part, except the unredeemed portion of any Security being redeemed in part; or
(iii) to exchange any Bearer Security so selected for redemption, except that
such a Bearer Security may be exchanged for a Registered Security of that series
and like tenor; provided that such Registered Security shall be simultaneously
surrendered for redemption.

         SECTION 3.6. REPLACEMENT SECURITIES. If a mutilated Security or a
Security with a mutilated coupon appertaining to it is surrendered to the
Trustee, together with, in proper cases, such security or indemnity as may be
required by the Company or the Trustee to save each of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver a
replacement Registered Security, if such surrendered Security was a Registered
Security, or a replacement Bearer Security with coupons corresponding to the
coupons appertaining to the surrendered Security, if such surrendered Security
was a Bearer Security, of the same series and date of maturity.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security or
Security with a destroyed, lost or

                                       28
<PAGE>

stolen coupon and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and the Trustee
shall authenticate and deliver in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a replacement Registered Security, if such Holder's claim appertains to a
Registered Security, or a replacement Bearer Security with coupons corresponding
to the coupons appertaining to the destroyed, lost or stolen Bearer Security or
the Bearer Security to which such lost, destroyed or stolen coupon appertains,
if such Holder's claim appertains to a Bearer Security, of the same series and
principal amount, containing identical terms and provisions and bearing a number
not contemporaneously outstanding with coupons corresponding to the coupons, if
any, appertaining to the destroyed, lost or stolen Security.

         In case any such mutilated, destroyed, lost or stolen Security or
coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security or coupon, pay such Security
or coupon; provided, however, that payment of principal of and any premium or
interest on Bearer Securities shall, except as otherwise provided in Section
9.2, be payable only at an office or agency located outside the United States
and, unless otherwise specified as contemplated by Section 3.1, any interest on
Bearer Securities shall be payable only upon presentation and surrender of the
coupons appertaining thereto.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee, its agents and
counsel) connected therewith.

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Security and its
coupon, if any, or the destroyed, lost or stolen coupon, 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 and their coupons, if any, duly issued hereunder.

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

         SECTION 3.7. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

                  (a)      Unless otherwise provided as contemplated by Section
3.1, interest, if any, on any Registered 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 at the office or agency maintained for such purpose pursuant
to 9.2; provided, however, that at the option of the Company, interest on any
series of Registered Securities that bear

                                       29
<PAGE>

interest may be paid (i) by check mailed to the address of the Person entitled
thereto as it shall appear on the Register of Holders of Securities of such
series or (ii) by wire transfer to an account maintained by the Person entitled
thereto as specified in the Register of Holders of Securities of such series.

         Unless otherwise provided as contemplated by Section 3.1, (A) (i)
interest, if any, on Bearer Securities shall be paid only against presentation
and surrender of the coupons for such interest installments as are evidenced
thereby as they mature and (ii) principal, original issue discount, if any, and
premium, if any, on Bearer Securities shall be paid only against presentation
and surrender of such Securities; in either case at the office of a Paying Agent
located outside the United States, unless the Company shall have otherwise
instructed the Trustee in writing provided that any such instruction for payment
in the United States does not cause any Bearer Security to be treated as a
"registration-required obligation" under United States laws and regulations; (B)
the interest, if any, on any temporary Bearer Security shall be paid, as to any
installment of interest evidenced by a coupon attached thereto only upon
presentation and surrender of such coupon as provided in clause (A) above and,
as to other installments of interest, only upon presentation of such Security
for notation thereon of the payment of such interest; and (C) if at the time a
payment of principal of premium, if any, or interest, if any, on a Bearer
Security or coupon shall become due, the payment of the full amount so payable
at the office or offices of all the Paying Agents outside the United States is
illegal or effectively precluded because of the imposition of exchange controls
or other similar restrictions on the payment of such amount in Dollars, then the
Company may instruct the Trustee to make such payment at a Paying Agent located
in the United States, provided that provision for such payment in the United
States would not cause such Bearer Security to be treated as a
"registration-required obligation" under United States laws and regulations.

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

                           (1)      The Company may elect to make payment of any
                                    Defaulted Interest to the Persons in whose
                                    names such Registered Securities of such
                                    series (or their respective Predecessor
                                    Securities) are registered at the close of
                                    business on a Special Record Date for the
                                    payment of such Defaulted Interest, which
                                    shall be fixed in the following manner. The
                                    Company shall 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 (1) 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

                                       30
<PAGE>

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

                           (2)      The Company may make payment of any
                                    Defaulted Interest to the Persons in whose
                                    names such Registered Securities of such
                                    series (or their respective Predecessor
                                    Securities) are registered at the close of
                                    business on a specified date in any other
                                    lawful manner not inconsistent with the
                                    requirements of any securities exchange on
                                    which such Registered Securities may be
                                    listed, and upon such notice as may be
                                    required by such exchange, if, after notice
                                    given by the Company to the Trustee of the
                                    proposed payment pursuant to this clause
                                    (2), such manner of payment shall be deemed
                                    practicable by the Trustee.

                  (c)      Subject to the foregoing provisions of this Section
and Section 3.5, 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 3.8. PERSONS DEEMED OWNERS. Prior to due presentment of any
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Registered Security for
the purpose of receiving payment of principal of, premium, if any, and (subject
to Section 3.7) interest and any other payments on such Registered Security and
for all other purposes whatsoever, whether or not such Registered Security shall
be overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security and the bearer of any coupon as the
absolute owner of such Bearer Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Bearer Security or coupon be overdue, and

                                       31
<PAGE>

neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

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

         SECTION 3.9. CANCELLATION. The Company at any time may deliver
Securities and coupons to the Trustee for cancellation. The Registrar and any
Paying Agent shall forward to the Trustee any Securities and coupons surrendered
to them for replacement, for registration of transfer, or for exchange or
payment. The Trustee shall cancel all Securities and coupons surrendered for
replacement, for registration of transfer, or for exchange, payment, redemption
or cancellation and may destroy cancelled Securities and coupons and, if so
destroyed, shall issue a certificate of destruction to the Company. The Company
may not issue new Securities to replace Securities that it has paid or delivered
to the Trustee for cancellation.

         SECTION 3.10. COMPUTATION OF INTEREST. Except as otherwise specified as
contemplated by Section 3.1, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

         SECTION 3.11. CURRENCY AND MANNER OF PAYMENT IN RESPECT OF SECURITIES.

                  (a)      Unless otherwise specified with respect to any
Securities pursuant to Section 3.1, with respect to Registered Securities of any
series and with respect to Bearer Securities of any series payment of the
principal of, premium, if any, interest, if any, and other amounts, if any, on
any Registered or Bearer Security of such series will be made in the currency or
currencies or currency unit or units in which such Registered Security or Bearer
Security, as the case may be, is payable. The provisions of this Section 3.11,
including without limitation any defined terms specified herein, may be modified
or superseded in whole or in part pursuant to Section 3.1 with respect to any
Securities.

                  (b)      If expressly specified pursuant to Section 3.1, with
respect to Registered Securities of any series, Holders shall have the option,
subject to paragraphs (d) and (e) below, to receive payments of principal of,
premium, if any, or interest, if any, on such Registered Securities in any of
the currencies or currency units which may be designated for such election by
delivering to the Trustee (or the applicable Paying Agent) a written election
with signature guarantees and in the applicable form established pursuant to
Section 3.1, not later than the close of business on the Election Date
immediately preceding the applicable payment date. If a Holder

                                       32
<PAGE>

so elects to receive such payments in any such currency or currency unit, such
election will remain in effect for such Holder or any transferee of such Holder
until changed by such Holder or such transferee by written notice to the Trustee
(or any applicable Paying Agent) for such series of Registered Securities (but
any such change must be made not later than the close of business on the
Election Date immediately preceding the next payment date to be effective for
the payment to be made on such payment date, and no such change of election may
be made with respect to payments to be made on any Registered Security of such
series with respect to which an Event of Default has occurred or with respect to
which the Company has deposited funds pursuant to Article IV or with respect to
which a notice of redemption has been given by or on behalf of the Company). Any
Holder of any such Registered Security who shall not have delivered any such
election to the Trustee (or any applicable Paying Agent) not later than the
close of business on the applicable Election Date will be paid the amount due on
the applicable payment date in the relevant currency or currency unit as
provided in Section 3.11(a). The Trustee (or the applicable Paying Agent) shall
notify the Company and the Exchange Rate Agent as soon as practicable after the
Election Date of the aggregate principal amount of Registered Securities for
which Holders have made such written election.

                  (c)      If the election referred to in paragraph (b) above
has been provided for with respect to any Registered Securities of a series
pursuant to Section 3.1, then, unless otherwise specified pursuant to Section
3.1 with respect to any such Registered Securities, not later than the fourth
Business Day after the Election Date for each payment date for such Registered
Securities, the Exchange Rate Agent will deliver to the Company a written notice
specifying, in the currency or currencies or currency unit or units in which
Registered Securities of such series are payable, the respective aggregate
amounts of principal of, premium, if any, and interest, if any, on such
Registered Securities to be paid on such payment date, and specifying the
amounts in such currency or currencies or currency unit or units so payable in
respect of such Registered Securities as to which the Holders of Registered
Securities denominated in any currency or currencies or currency unit or units
shall have elected to be paid in another currency or currency unit as provided
in paragraph (b) above. If the election referred to in paragraph (b) above has
been provided for with respect to any Registered Securities of a series pursuant
to Section 3.1, and if at least one Holder has made such election, then, unless
otherwise specified pursuant to Section 3.1, on the second Business Day
preceding such payment date the Company will deliver to the Trustee (or the
applicable Paying Agent) an Exchange Rate Officers' Certificate in respect of
the Dollar, Foreign Currency or Currencies or other currency unit payments to be
made on such payment date. Unless otherwise specified pursuant to Section 3.1,
the Dollar, Foreign Currency or Currencies or other currency unit amount
receivable by Holders of Registered Securities who have elected payment in a
currency or currency unit as provided in paragraph (b) above shall be determined
by the Company on the basis of the applicable Market Exchange Rate in effect on
the second Business Day (the "Valuation Date") immediately preceding each
payment date, and such determination shall be conclusive and binding for all
purposes, absent manifest error.

                  (d)      If a Conversion Event occurs with respect to a
Foreign Currency or any other currency unit in which any of the Securities are
denominated or payable otherwise than pursuant to an election provided for
pursuant to paragraph (b) above, then, unless otherwise specified pursuant to
Section 3.1, with respect to each date for the payment of principal of, premium,
if any, and interest, if any, on the applicable Securities denominated or
payable in such

                                       33
<PAGE>

Foreign Currency or such other currency unit occurring after the last date on
which such Foreign Currency or such other currency unit was used (the
"Conversion Date"), the Dollar shall be the currency of payment for use on each
such payment date (but such Foreign Currency or such other currency unit that
was previously the currency of payment shall, at the Company's election, resume
being the currency of payment on the first such payment date preceded by 15
Business Days during which the circumstances which gave rise to the Dollar
becoming such currency of payment no longer prevail). Unless otherwise specified
pursuant to Section 3.1, the Dollar amount to be paid by the Company to the
Trustee or any applicable Paying Agent and by the Trustee or any applicable
Paying Agent to the Holders of such Securities with respect to such payment date
shall be, in the case of a Foreign Currency other than a currency unit, the
Dollar Equivalent of the Foreign Currency or, in the case of a Foreign Currency
that is a currency unit, the Dollar Equivalent of the Currency Unit, in each
case as determined by the Exchange Rate Agent in the manner provided in
paragraph (f) or (g) below.

                  (e)      Unless otherwise specified pursuant to Section 3.1,
if the Holder of a Registered Security denominated in any currency or currency
unit shall have elected to be paid in another currency or currency unit or in
other currencies as provided in paragraph (b) above, and (i) a Conversion Event
occurs with respect to any such elected currency or currency unit, such Holder
shall receive payment in the currency or currency unit in which payment would
have been made in the absence of such election and (ii) if a Conversion Event
occurs with respect to the currency or currency unit in which payment would have
been made in the absence of such election, such Holder shall receive payment in
Dollars as provided in paragraph (d) of this Section 3.11 (but, subject to any
contravening valid election pursuant to paragraph (b) above, the elected payment
currency or currency unit, in the case of the circumstances described in clause
(i) above, or the payment currency or currency unit in the absence of such
election, in the case of the circumstances described in clause (ii) above,
shall, at the Company's election, resume being the currency or currency unit of
payment with respect to Holders who have so elected, but only with respect to
payments on payment dates preceded by 15 Business Days during which the
circumstances which gave rise to such currency or currency unit, in the case of
the circumstances described in clause (i) above, or the Dollar, in the case of
the circumstances described in clause (ii) above, becoming the currency or
currency unit, as applicable, of payment, no longer prevail).

                  (f)      The "Dollar Equivalent of the Foreign Currency" shall
be determined by the Exchange Rate Agent and shall be obtained for each
subsequent payment date by the Exchange Rate Agent by converting the specified
Foreign Currency into Dollars at the Market Exchange Rate on the Conversion
Date.

                  (g)      The "Dollar Equivalent of the Currency Unit" shall be
determined by the Exchange Rate Agent and, subject to the provisions of
paragraph (h) below, shall be the sum of each amount obtained by converting the
Specified Amount of each Component Currency (as each such term is defined in
paragraph (h) below) into Dollars at the Market Exchange Rate for such Component
Currency on the Valuation Date with respect to each payment.

                  (h)      For purposes of this Section 3.11, the following
terms shall have the following meanings:

                                       34
<PAGE>

         A "Component Currency" shall mean any currency which, on the Conversion
Date, was a component currency of the relevant currency unit.

         "Conversion Event" shall mean the cessation of use of (i) a Foreign
Currency both by the government of the country which issued such currency and
for the settlement of transactions by a central bank or other public
institutions of or within the international banking community, or (ii) any
currency unit for the purposes for which it was established.

         "Election Date" shall mean the Regular Record Date for the applicable
series of Registered Securities as specified pursuant to Section 3.1 by which
the written election referred to in Section 3.11(b) may be made.

         "Exchange Rate Agent," when used with respect to Securities of or
within any series, shall mean, unless otherwise specified with respect to any
Securities pursuant to Section 3.1, a ____________________ bank designated
pursuant to Section 3.1 or Section 3.12.

         "Exchange Rate Officer's Certificate" shall mean a certificate setting
forth (i) the applicable Market Exchange Rate or the applicable bid quotation
and (ii) the Dollar or Foreign Currency amounts of principal (and premium, if
any) and interest, if any (on an aggregate basis and on the basis of a Security
having the lowest denomination principal amount in the relevant currency or
currency unit), payable with respect to a Security of any series on the basis of
such Market Exchange Rate or the applicable bid quotation, signed by the
President, the Chief Executive Officer, the Chief Financial Officer, any Vice
President, the Treasurer, or any Assistant Treasurer of the Company.

         "Market Exchange Rate" shall mean, unless otherwise specified with
respect to any Securities pursuant to Section 3.1, as of any date of
determination, (i) for any conversion involving a currency unit on the one hand
and Dollars or any Foreign Currency on the other, the exchange rate between the
relevant currency unit and Dollars or such Foreign Currency calculated by the
method specified pursuant to Section 3.1 for the Securities of the relevant
series, (ii) for any conversion of Dollars into any Foreign Currency, the noon
buying rate for such Foreign Currency for cable transfers quoted in New York
City as certified for customs purposes by the Federal Reserve Bank of New York
and (iii) for any conversion of one Foreign Currency into Dollars or another
Foreign Currency, the spot rate at noon local time in the relevant market at
which, in accordance with normal banking procedures, the Dollars or Foreign
Currency into which conversion is being made could be purchased with the Foreign
Currency from which conversion is being made from major banks located in New
York City, London or any other principal market for Dollars or such purchased
Foreign Currency, in each case determined by the Exchange Rate Agent. Unless
otherwise specified with respect to any Securities pursuant to Section 3.1, in
the event of the unavailability of any of the exchange rates provided for in the
foregoing clauses (i), (ii) and (iii), the Exchange Rate Agent shall use, in its
sole discretion and without liability on its part, such quotation of the Federal
Reserve Bank of New York as of the most recent available date, or quotations
from one or more major banks in New York City, London or other principal market
for such currency or currency unit in question (which may include any such bank
acting as Trustee under this Indenture), or such other quotations as the
Exchange Rate Agent shall deem appropriate. Unless otherwise specified by the
Exchange Rate Agent, if there is more than one market for dealing in any
currency or

                                       35
<PAGE>

currency unit by reason of foreign exchange regulations or otherwise, the market
to be used in respect of such currency or currency unit shall be that upon which
a nonresident issuer of securities designated in such currency or currency unit
would purchase such currency or currency unit in order to make payments in
respect of such securities.

         A "Specified Amount" of a Component Currency shall mean the number of
units of such Component Currency or fractions thereof which such Component
Currency represented in the relevant currency unit on the Conversion Date. If
after the Conversion Date the official unit of any Component Currency is altered
by way of combination or subdivision, the Specified Amount of such Component
Currency shall be divided or multiplied in the same proportion. If after the
Conversion Date two or more Component Currencies are consolidated into a single
currency, the respective Specified Amounts of such Component Currencies shall be
replaced by an amount in such single currency equal to the sum of the respective
Specified Amounts of such consolidated Component Currencies expressed in such
single currency, and such amount shall thereafter be a Specified Amount and such
single currency shall thereafter be a Component Currency. If after the
Conversion Date any Component Currency shall be divided into two or more
currencies, the Specified Amount of such Component Currency shall be replaced by
specified amounts of such two or more currencies, the sum of which, at the
Market Exchange Rate of such two or more currencies on the date of such
replacement, shall be equal to the Specified Amount of such former Component
Currency and such amounts shall thereafter be Specified Amounts and such
currencies shall thereafter be Component Currencies. If, after the Conversion
Date of the relevant currency unit, a Conversion Event (other than any event
referred to above in this definition of "Specified Amount") occurs with respect
to any Component Currency of such currency unit and is continuing on the
applicable Valuation Date, the Specified Amount of such Component Currency
shall, for purposes of calculating the Dollar Equivalent of the Currency Unit,
be converted into Dollars at the Market Exchange Rate in effect on the
Conversion Date of such Component Currency.

         All decisions and determinations of the Exchange Rate Agent regarding
the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the
Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as
specified above shall be in its sole discretion and shall, in the absence of
manifest error, be conclusive for all purposes and irrevocably binding upon the
Company, the Trustee (and any applicable Paying Agent) and all Holders of
Securities denominated or payable in the relevant currency, currencies or
currency units. The Exchange Rate Agent shall promptly give written notice to
the Company and the Trustee of any such decision or determination.

         In the event that the Company determines in good faith that a
Conversion Event has occurred with respect to a Foreign Currency, the Company
will promptly give written notice thereof to the Trustee (or any applicable
Paying Agent) and to the Exchange Rate Agent (and the Trustee (or such Paying
Agent) will promptly thereafter give notice in the manner provided in Section
1.6 to the affected Holders) specifying the Conversion Date. In the event the
Company so determines that a Conversion Event has occurred with respect to any
currency unit in which Securities are denominated or payable, the Company will
promptly give written notice thereof to the Trustee (or any applicable Paying
Agent) and to the Exchange Rate Agent (and the Trustee (or such Paying Agent)
will promptly thereafter give notice in the manner provided in Section 1.6 to
the affected Holders) specifying the Conversion Date and the Specified Amount of

                                       36
<PAGE>

each Component Currency on the Conversion Date. In the event the Company
determines in good faith that any subsequent change in any Component Currency as
set forth in the definition of Specified Amount above has occurred, the Company
will similarly give written notice to the Trustee (or any applicable Paying
Agent) and to the Exchange Rate Agent.

         The Trustee of the appropriate series of Securities shall be fully
justified and protected in relying and acting upon information received by it
from the Company and the Exchange Rate Agent and shall not otherwise have any
duty or obligation to determine the accuracy or validity of such information
independent of the Company or the Exchange Rate Agent.

         SECTION 3.12. APPOINTMENT AND RESIGNATION OF EXCHANGE RATE AGENT.

                  (a)      Unless otherwise specified pursuant to Section 3.1,
if and so long as the Securities of any series (i) are denominated in a currency
or currency unit other than Dollars or (ii) may be payable in a currency or
currency unit other than Dollars, or so long as it is required under any other
provision of this Indenture, then the Company will maintain with respect to each
such series of Securities, or as so required, at least one Exchange Rate Agent.
The Company will cause the Exchange Rate Agent to make the necessary foreign
exchange determinations at the time and in the manner specified pursuant to
Section 3.11 for the purpose of determining the applicable rate of exchange and,
if applicable, for the purpose of converting the issued currency or currencies
or currency unit or units into the applicable payment currency or currency unit
for the payment of principal, premium, if any, and interest, if any, pursuant to
Section 3.11.

                  (b)      No resignation of the Exchange Rate Agent and no
appointment of a successor Exchange Rate Agent pursuant to this Section shall
become effective until the acceptance of appointment by the successor Exchange
Rate Agent as evidenced by a written instrument delivered to the Company and the
Trustee of the appropriate series of Securities accepting such appointment
executed by the successor Exchange Rate Agent.

                  (c)      If the Exchange Rate Agent shall resign, be removed
or become incapable of acting, or if a vacancy shall occur in the office of the
Exchange Rate Agent for any cause, with respect to the Securities of one or more
series, the Company shall promptly appoint a successor Exchange Rate Agent or
Exchange Rate Agents with respect to the Securities of that or those series (it
being understood that any such successor Exchange Rate Agent may be appointed
with respect to the Securities of one or more or all of such series and that,
unless otherwise specified pursuant to Section 3.1, at any time there shall only
be one Exchange Rate Agent with respect to the Securities of any particular
series that are originally issued by the Company on the same date and that are
initially denominated and/or payable in the same currency or currencies or
currency unit or units).

         SECTION 3.13. WIRE TRANSFERS. Notwithstanding any other provisions to
the contrary in this Indenture, the Company may make any payment of monies
required to be deposited with the Trustee on account of principal of, or
premium, if any, or interest on, the Securities (whether pursuant to optional or
mandatory redemption payments, interest payment or otherwise) by wire transfer
and immediately available funds to an account designated by the

                                       37

Trustee on or before the date and time such monies are to be paid to the Holders
of the Security in accordance with the terms hereof.

         SECTION 3.14. CUSIP NUMBERS. The Company in issuing Securities may use
"CUSIP" numbers (if then generally in use), and if so, the Trustee may use the
CUSIP numbers in notices of redemption or exchange as a convenience to Holders;
provided, however, that any such notice may state that no representation is made
as to the correctness or accuracy of the CUSIP number printed in the notice or
on the Securities, that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption or exchange shall not
be affected by any defect or omission of such CUSIP numbers. The Company will
promptly notify the Trustee of any change in CUSIP numbers known to an Officer
of the Company.

                                    Indenture as to such series have been
                                    complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligation of the Company to the Trustee and any predecessor Trustee under
Section 6.8 and the obligations of the Company to any Authenticating Agent under
Section 6.13 shall survive until the Securities of the discharged series have
been paid in full, and, if money shall have been deposited with the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 4.2 and the last paragraph of Section 9.3 shall survive in
accordance with the terms of such Sections.

         SECTION 4.2. APPLICATION OF TRUST FUNDS. Subject to the provisions of
the last paragraph of Section 9.3, all money deposited with the Trustee pursuant
to Section 4.1 shall be held in trust and applied by it, in accordance with the
provisions of the Securities, the coupons and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Persons entitled

                                       39

such money has been deposited with or received by the Trustee, but such money
need not be segregated from other funds except to the extent required by law.

         SECTION 4.3. APPLICABILITY OF DEFEASANCE PROVISIONS; COMPANY'S OPTION
TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE. Unless pursuant to Section 3.1
provision is made to exclude with respect to the Securities of a particular
series either or both of (i) defeasance of the Securities of or within such
series under Section 4.4 or (ii) covenant defeasance of the Securities of or
within such series under Section 4.5, then, in addition to the rights of the
Company pursuant to Section 4.1 above, the provisions of such Section or
Sections, as the case may be, together with the provisions of Sections 4.6
through 4.9 inclusive, with such modifications thereto as may be specified
pursuant to Section 3.1 with respect to any Securities of such series, shall be
applicable to such Securities and any coupons appertaining thereto, and the
Company may at its option, at any time, with respect to such Securities and any
coupons appertaining thereto, elect to have Section 4.4 (if applicable) or
Section 4.5 (if applicable) be applied to such Outstanding Securities and any
coupons appertaining thereto upon compliance with the conditions set forth below
in this Article.

         SECTION 4.4. DEFEASANCE AND DISCHARGE. Upon the Company's exercise of
the option specified in Section 4.3 applicable to this Section with respect to
the Securities of or within a series, the Company shall be deemed to have been
discharged from its obligations with respect to such Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 4.6 are
satisfied (hereinafter, a "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities and any coupons appertaining
thereto, which Securities and coupons appertaining thereto shall thereafter be
deemed to be "Outstanding" only for the purposes of Section 4.7 and the other
Sections of this Indenture referred to in clause (ii) of this Section, and to
have satisfied all its other obligations under such Securities and any coupons
appertaining thereto and this Indenture insofar as such Securities and any
coupons appertaining thereto are concerned (and the Trustee, at the expense of
the Company, shall on Company Order execute proper instruments acknowledging the
same), except the following which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of such Securities and any
coupons appertaining thereto to receive, solely from the trust funds described
in Section 4.6(a) and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest, if any, on such
Securities or any coupons appertaining thereto when such payments are due; (ii)
the Company's obligations with respect to such Securities under Sections 3.5,
3.6, 9.2 and 9.3 and with respect to the payment of additional amounts, if any,
payable with respect to such Securities as specified pursuant to Section 3.1(b)
(18); (iii) the rights, powers, trusts, duties, immunities and indemnities of
the Trustee hereunder and (iv) this Article IV. Subject to compliance with this
Article IV, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 4.5 with respect
to such Securities and any coupons appertaining thereto. Following a defeasance,
payment of such Securities may not be accelerated because of an Event of
Default.

         SECTION 4.5. COVENANT DEFEASANCE. Upon the Company's exercise of the
option specified in Section 4.3 applicable to this Section with respect to any
Securities of or within a series, the Company shall be released from its
obligations under Sections 7.1, 9.4 and

                                       40
<PAGE>

9.5, and, if specified pursuant to Section 3.1, its obligations under any
other covenant, with respect to such Securities and any coupons appertaining
thereto on and after the date the conditions set forth in Section 4.6 are
satisfied (hereinafter, "covenant defeasance"), and such Securities and any
coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any direction, waiver, consent or declaration or Act of
Holders (and the consequences of any thereof) in connection with Sections 7.1,
9.4 and 9.5, or such other specified covenant, and the operation of Sections
5.1(3) and 5.1(6), but shall continue to be deemed "Outstanding" for all other
purposes hereunder. For this purpose, such covenant defeasance means that, with
respect to such Securities and any coupons appertaining thereto, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or such other covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such Section or such other covenant or by reason of reference in any such
Section or such other covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 5.1(3) or 5.1(6) or otherwise, as the case may be, but,
except as specified above, the remainder of this Indenture and such Securities
and any coupons appertaining thereto shall be unaffected thereby.

         SECTION 4.6. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The
following shall be the conditions to application of Section 4.4 or Section 4.5
to any Securities of or within a series and any coupons appertaining thereto:

                           Before such a deposit the Company may make
                           arrangements satisfactory to the Trustee for the
                           redemption of Securities at a future date or dates in
                           accordance with Article X which shall be given effect
                           in applying the foregoing.

                  (b)      The deposit pursuant to subsection (a) above shall
                           not result in or constitute a Default or Event of
                           Default under this Indenture or result in a breach or
                           violation of, or constitute a default under, any
                           other material agreement or instrument to which the
                           Company is a party or by which it is bound.

                  (c)      In the case of an election under Section 4.4, no
                           Default or Event of Default under Section 5.1(4) or
                           5.1(5) with respect to such Securities and any
                           coupons appertaining thereto shall have occurred and
                           be continuing during the period commencing on the
                           date of such deposit and ending on the 91st day after
                           such date (it being understood that this condition
                           shall not be deemed satisfied until the expiration of
                           such period).

                  (d)      In the case of an election under Section 4.4, the
                           Company shall have delivered to the Trustee an
                           Officers' Certificate and an Opinion of Counsel to
                           the effect that (i) the Company has received from, or
                           there has been published by, the Internal Revenue
                           Service a ruling, or (ii) since the date of execution
                           of this Indenture, there has been a change in the
                           applicable Federal income tax law, in either case to
                           the effect that, and based thereon such opinion shall
                           confirm that, the Holders of such Securities and any
                           coupons appertaining thereto 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 and in the
                           same manner and at the same times, as would have been
                           the case if such deposit, defeasance and discharge
                           had not occurred.

                  (e)      In the case of an election under Section 4.5, the
                           Company shall have delivered to the Trustee an
                           Opinion of Counsel to the effect that the Holders of
                           such Securities and any coupons appertaining thereto
                           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.

                  (f)      The Company shall have delivered to the Trustee an
                           Officers' Certificate and an Opinion of Counsel, each
                           stating that all conditions precedent to the
                           defeasance under Section 4.4 or the covenant
                           defeasance under Section 4.5 (as the case may be)
                           have been complied with and an Opinion of Counsel to
                           the effect that either (i) as a result of a deposit
                           pursuant to subsection (a) above and the related
                           exercise of the Company's option under Section 4.4 or
                           Section 4.5 (as the case may be), registration is not
                           required under the Investment Company Act of 1940, as
                           amended, by the

                           Company, with respect to the trust funds representing
                           such deposit or by the trustee for such trust funds
                           or (ii) all necessary registrations under said act
                           have been effected.

                  (g)      Such defeasance or covenant defeasance shall be
                           effected in compliance with any additional or
                           substitute terms, conditions or limitations which may
                           be imposed on the Company in connection therewith as
                           contemplated by Section 3.1.

         SECTION 4.7. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST. Subject to the provisions of the last paragraph of Section 9.3, all money
and Government Obligations (or other property as may be provided pursuant to
Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.6 in respect of any Securities of any series and any
coupons appertaining thereto shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities and any coupons
appertaining thereto and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Holders of such Securities and any coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal, premium, if any, and interest, if any, but such money need not be
segregated from other funds except to the extent required by law.

         If specified with respect to any Security pursuant to Section 3.1, if,
after a deposit referred to in Section 4.6(a) has been made, (i) the Holder of a
Security in respect of which such deposit was made is entitled to, and does,
elect pursuant to Section 3.11(b) or the terms of such Security to receive
payment in a currency or currency unit other than that in which the deposit
pursuant to Section 4.6(a) has been made in respect of such Security, or (ii) a
Conversion Event occurs as contemplated in Section 3.11(d) or 3.11(e) or by the
terms of any Security in respect of which the deposit pursuant to Section 4.6(a)
has been made, the indebtedness represented by such Security and any coupons
appertaining thereto shall be deemed to have been, and will be, fully discharged
and satisfied through the payment of the principal of, premium, if any, and
interest, if any, on such Security as the same becomes due out of the proceeds
yielded by converting (from time to time as specified below in the case of any
such election) the amount or other property deposited in respect of such
Security into the currency or currency unit in which such Security becomes
payable as a result of such election or Conversion Event based on the applicable
Market Exchange Rate for such currency or currency unit in effect on the second
Business Day prior to each payment date, except, with respect to a Conversion
Event, for such currency or currency unit in effect (as nearly as feasible) at
the time of the Conversion Event.

         SECTION 4.8. REPAYMENT TO COMPANY. The Trustee (and any Paying Agent)
shall promptly pay to the Company upon Company Request any excess money or
securities held by them at any time.

         SECTION 4.9. INDEMNITY FOR GOVERNMENT OBLIGATIONS. The Company shall
pay, and shall indemnify the Trustee against, any tax, fee or other charge
imposed on or assessed against Government Obligations deposited pursuant to this
Article or the principal and interest received on such Government Obligations,
other than any such tax, fee or other charge

that by law is for the account of the Holders of the Securities subject to
defeasance or covenant defeasance pursuant to this Article.

be voluntary or involuntary or be effected by operation of law or pursuant to
any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body):

                           (1)      the Company defaults in the payment of
                                    interest on any Security of that series or
                                    any coupon appertaining thereto or any
                                    additional amount payable with respect to
                                    any Security of that series as specified
                                    pursuant to Section 3.1(b)(17) when the same
                                    becomes due and payable and such default
                                    continues for a period of 30 days;

                           (2)      the Company defaults in the payment of the

                                    of that series when the same becomes due and
                                    payable at its Maturity or on redemption or
                                    otherwise, or in the payment of a mandatory

                                    terms of the Securities of that series;

                           (3)      the Company defaults in the performance of,
                                    or breaches, any covenant or warranty of the
                                    Company in this Indenture with respect to
                                    any Security of that series (other than a
                                    covenant or warranty a default in whose
                                    performance or whose breach is elsewhere in
                                    this Section specifically dealt with), and
                                    such default or breach continues for a
                                    period of 90 days after there has been
                                    given, by registered or certified mail, to
                                    the Company by the Trustee or to the Company
                                    and the Trustee by the Holders of 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;

                           (4)      the Company, pursuant to or within the
                                    meaning of any Bankruptcy Law, (A) commences
                                    a voluntary case, (B) consents to the entry
                                    of an order for relief against it in an
                                    involuntary case, (C) consents to the
                                    appointment of a Custodian of it or for all
                                    or substantially all of its property, or (D)
                                    makes a general assignment for the benefit
                                    of its creditors;

<PAGE>

                           (5)      a court of competent jurisdiction enters an
                                    order or decree under any Bankruptcy Law
                                    that (A) is for relief against the Company
                                    in an involuntary case, (B) appoints a
                                    Custodian of the Company or for all or
                                    substantially all of its property, or (C)
                                    orders the liquidation of the Company; and
                                    the order or decree remains unstayed and in
                                    effect for 90 days; or

                           (6)      any other Event of Default provided as

                                    Securities of that series. The term
                                    "Bankruptcy Law" means Title 11, U.S. Code,
                                    or any similar federal or state law for the
                                    relief of debtors. The term "Custodian"

                                    liquidator or similar official under any
                                    Bankruptcy Law.

         SECTION 5.2. ACCELERATION; RESCISSION AND ANNULMENT. If an Event of
Default with respect to the Securities of any series at the time Outstanding
occurs and is continuing, the Trustee or the Holders of at least 25% in
aggregate principal amount of all of the Outstanding Securities of that series,
by written notice to the Company (and, if given by the Holders, to the Trustee),
may declare the principal (or, if the Securities of that series are Original
Issue Discount Securities or Indexed Securities, such portion of the principal
amount or other amount as may be specified in the terms of that series) of all
the Securities of that series to be due and payable and upon any such
declaration such principal (or, in the case of Original Issue Discount
Securities or Indexed Securities, such specified amount) shall be immediately
due and payable. At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series, by written notice
to the Trustee, may rescind and annul such declaration and its consequences if
all existing Defaults and Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 5.7. Upon any such rescission, the
parties hereto shall be restored respectively to their several positions and
rights hereunder, and all rights, remedies and powers of the parties hereto
shall continue as though no acceleration had occurred.

         SECTION 5.3. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE. The Company covenants that if

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

                           (2)      default is made in the payment of the
                                    principal of (or premium, if any, on) any
                                    Security of any series at the Maturity
                                    thereof and such default continues for a
                                    period of 10 days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such

                                       45
<PAGE>

Securities or coupons, if any, the whole amount then due and payable on such
Securities for principal, premium, if any, and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal, premium, if any, and on any overdue interest, at the rate or rates
prescribed therefor in such Securities or coupons.

         If the Company fails to pay such principal, premium, if any, and
interest amounts forthwith upon such demand, the Trustee, in its own name and as
trustee of an express trust, may institute a judicial proceeding for the
collection of such principal, premium, if any, and interest amounts so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company.

         In addition, if an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed, in
its own name and as trustee of an express trust, 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 5.4. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders of
Securities allowed in any judicial proceedings relating to the Company, its
creditors or its property.

         SECTION 5.5. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee, in its own name and as
trustee of an express trust, without the possession of any of the Securities or
the production thereof in any proceeding relating thereto.

         SECTION 5.6. DELAY OR OMISSION NOT WAIVER. No delay or omission by the
Trustee or any Holder of any Securities to exercise any right or remedy accruing
upon an Event of Default shall impair any such right or remedy or constitute a
waiver of or acquiescence in any such Event of Default.

         SECTION 5.7. WAIVER OF PAST DEFAULTS. The Holders of a majority in
aggregate principal amount of Outstanding Securities of any series by notice to
the Trustee may waive on behalf of the Holders of all Securities of such series
a past Default or Event of Default with respect to that series and its
consequences except a Default or Event of Default (i) in the payment of the
principal of, premium, if any, or interest on any Security of such series or any
coupon appertaining thereto or (ii) in respect of a covenant or provision hereof
which pursuant to Section 8.2 cannot be amended or modified without the consent
of the Holder of each Outstanding Security of such series adversely affected.
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon. In case of
any such

                                       46
<PAGE>

waiver, the Company, the Trustee and the Holders shall be restored to their
former positions and rights hereunder and under the Securities of such series,
respectively.

         SECTION 5.8. CONTROL BY MAJORITY. The Holders of a majority in
aggregate principal amount of the Outstanding Securities of each series affected
(with each such series voting as a class) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on it with respect to
Securities of that series; provided, however, that (i) the Trustee may refuse to
follow any direction that conflicts with law or this Indenture, (ii) the Trustee
may refuse to follow any direction that is unduly prejudicial to the rights of
the Holders of Securities of such series not consenting, or that would in the
good faith judgment of the Trustee have a substantial likelihood of involving
the Trustee in personal liability and (iii) the Trustee may take any other
action deemed proper by the Trustee which is not inconsistent with such
direction.

         SECTION 5.9. LIMITATION ON SUITS BY HOLDERS. No Holder of any Security
of any series or any coupons appertaining thereto shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

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

                           (2)      the Holders of at least 25% in aggregate
                                    principal amount of the Outstanding
                                    Securities of that series have made a
                                    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 indemnity satisfactory to the
                                    Trustee against any loss, liability or
                                    expense to be, or which may be, incurred by
                                    the Trustee in pursuing the remedy;

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

                           (5)      during such 60 day period, the Holders of a
                                    majority in aggregate principal amount of
                                    the Outstanding Securities of that series
                                    have not given to the Trustee a direction
                                    inconsistent with such written request.

         No one or more 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.

                                       47

         SECTION 5.10. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any
other provision of this Indenture, but subject to Section 9.2, the right of any
Holder of a Security or coupon of any series to receive payment of principal of,
premium, if any, and, subject to Sections 3.5 and 3.7, interest on the Security,
on or after the respective due dates expressed in the Security (or, in case of
redemption, on the redemption dates), and the right of any Holder of a coupon to
receive payment of interest due as provided in such coupon, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder.

         SECTION 5.11. APPLICATION OF MONEY COLLECTED. If the Trustee collects
any money pursuant to this Article, it shall pay out the money 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, premium, if any, or
interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  First: to the Trustee for amounts due under Section 6.8 in
                  connection with such series of Securities in respect of which
                  money or other property is collected;

                  Second: Subject to the terms of any subordination entered into
                  as contemplated by Section 3.1(b) (27) hereof, to Holders of
                  Securities of such series and coupons in respect of which or
                  for the benefit of which such money has been collected for
                  amounts due and unpaid on such Securities for principal of,
                  premium, if any, and interest, ratably, without preference or
                  priority of any kind, according to the amounts due and payable
                  on such Securities for principal, premium, if any, and
                  interest, respectively; and

                  Third: The balance, if any, to the Company.

         The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 5.11. At least 15 days before such record date,
the Trustee shall mail to each Holder and the Company a notice that states the
record date, the payment date and the amount to be paid.

         Unless otherwise specified in a supplemental indenture with respect to
a series of Securities, in any case where Securities are outstanding which are
denominated in more than one currency, or in a composite currency and at least
one other currency, and the Trustee is directed to make ratable payments under
this Section to Holders of Securities, the Trustee shall calculate the amount of
such payments as follows: as of the day the Trustee collects an amount under
this Article, the Trustee shall, (i) as to each Holder of a Security to whom an
amount is due and payable under this Section which is denominated in a foreign
currency or a composite currency, determine that amount of Dollars that would be
obtained for the amount owing such Holder, using the rate of exchange at which
in accordance with normal banking procedures the Trustee could purchase in
Dollars as of such day with such amount owing, (ii) calculate the sum of all
Dollar amounts determined under (i) and add thereto any amounts due and payable
in Dollars; and (iii) using the individual amounts determined in (i) or any
individual amounts due and

                                       48
<PAGE>

payable in Dollars, as the case may be, as a numerator and the sum calculated in
(ii) as a denominator, calculate as to each Holder of a Security to whom an
amount is owed under this Section the fraction of the amount collected under
this Article payable to such Holder. Any expenses incurred by the Trustee in
actually converting amounts owing Holders of Securities denominated in a
currency or composite currency other than that in which any amount is collected
under this Article shall be likewise (in accordance with this paragraph) be
borne ratably by all Holders of Securities to whom amounts are payable under
this Section.

         Unless otherwise specified in the supplemental indenture with respect
to a series of Securities, to the fullest extent allowed under applicable law,
if for the purpose of obtaining judgment against the Company in any court it is
necessary to convert the sum due in respect of the principal of, or any premium
or interest on the Securities of any series (the "Required Currency") into a
currency in which judgment will be rendered (the "Judgment Currency"), the rate
of exchange used shall be the rate at which in accordance with normal banking
procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the New York Business Day preceding that
on which final judgment is given. The Company shall not be liable for any
shortfall in payments to Holders of Securities under this Section caused by a
change in exchange rates between the time the amount of a judgment against it is
calculated as above and the time the Trustee converts the Judgment Currency into
the Required Currency to make payments under this Section to Holders of
Securities, but payment of such judgment shall discharge all amounts owed by the
Company on the claim or claims underlying such judgment.

         SECTION 5.12. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to such Holder, then and in
every such case, subject to any determination in such proceeding, the Company,
the Trustee and the Holders shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

         SECTION 5.13. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise
provided in Section 5.9 or with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
3.6, no right or remedy herein conferred upon or reserved to the Trustee or the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

                                   ARTICLE VI

                                   THE TRUSTEE

         SECTION 6.1. RIGHTS OF TRUSTEE. Subject to the applicable provisions of
the Trust Indenture Act:

                  (a)      The Trustee may conclusively rely and shall be
protected in acting or refraining from acting upon any document believed by it
to be genuine and to have been signed or presented by the proper party or
parties. The Trustee need not investigate any fact or matter stated in the
document, and may conclusively rely, in good faith, as to the truth of the
statements and concerns of the opinions expressed therein.

                  (b)      Any request or direction of the Company mentioned
herein shall be sufficiently evidenced by a Company Request or Company Order
(other than delivery of any Security, together with any coupons appertaining
thereto, to the Trustee for authentication and delivery pursuant to Section 3.3,
which shall be sufficiently evidenced as provided therein) and any resolution of
the Board of Directors may be sufficiently evidenced by a Board Resolution.

                  (c)      Before the Trustee acts or refrains from acting, it
may consult with counsel or require an Officers' Certificate. The Trustee shall
not be liable for any action it takes or omits to take in good faith in reliance
on a Board Resolution, the written advice of counsel acceptable to the Trustee,
a certificate of an Officer or Officers delivered pursuant to Section 1.2, an
Officers' Certificate or an Opinion of Counsel.

                  (d)      The Trustee may act through agents or attorneys and
shall not be responsible for the misconduct or negligence of any agent or
attorney appointed with due care.

                  (e)      The Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be authorized or
within its discretion or rights or powers.

                  (f)      The Trustee shall not be required to expend or risk
its own funds or otherwise incur any financial liability in the performance of
any of its duties hereunder, or in the exercise of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

                  (g)      Except during the continuance of an Event of Default,
the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee.

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

                  (i)      The Trustee shall not be liable with respect to any
action taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders of a majority in aggregate principal amount of the
Outstanding Securities (pursuant to Section 5.8) relating to the

                                       50
<PAGE>

time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture.

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

                  (k)      Any permissive right of the Trustee hereunder shall
not be construed to be a duty.

                  (l)      The Trustee shall not be charged with knowledge of
any Event of Default, other than as described in Section 5.1(1) or (2), unless
and except to the extent actually known by a Responsible Officer of the Trustee
or written notice thereof is received by the Trustee at its Corporate Trust
Office. Notwithstanding anything contained herein to the contrary, in case an
Event of Default with respect to the Securities of any series has occurred and
is continuing, and is known to the Trustee, the Trustee shall exercise, with
respect to Securities of such series, such of the rights and powers vested in it
by this Indenture, and shall use the same degree of care and skill in their
exercise, as a prudent individual would exercise or use under the circumstances
in the conduct of his or her own affairs.

         SECTION 6.2. TRUSTEE MAY HOLD SECURITIES. The Trustee, any Paying
Agent, any Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and coupons and,
subject to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise
deal with the Company, an Affiliate or Subsidiary with the same rights it would
have if it were not Trustee, Paying Agent, Registrar or such other agent.

         SECTION 6.3. MONEY HELD IN TRUST. Subject to the provisions of Section
4.8 and the last paragraph of Section 9.3, all moneys received by the Trustee
shall, until used or applied as herein provided, be held in trust for the
purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for investment of or interest on any money received by it hereunder
except as otherwise agreed with the Company. Except for amounts deposited
pursuant to Article Four, so long as no Event of Default shall have occurred and
be continuing, all interest allowed on any such moneys shall be paid from time
to time to the Company upon a Company Order. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law.

         SECTION 6.4. TRUSTEE'S DISCLAIMER. The recitals contained herein and in
the Securities, except the Trustee's certificate of authentication, shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representation as to
the validity or adequacy of this Indenture or the Securities or any coupon,
except that the Trustee represents and warrants that it is duly authorized to
execute and

                                       51
<PAGE>

deliver this Indenture, authenticate the Securities and perform its obligations
hereunder and thereunder; that the statements made by it in a Statement of
Eligibility and Qualification on Form T-1 supplied or to be supplied to the
Company in connection with the registration of any Securities are and at the
time of delivery will be true and accurate; and that such Statement complies and
at the time of delivery will comply with the requirements of the Trust Indenture
Act and the Securities Act, in each case, applicable to such Statement. The
Trustee shall not be accountable for the Company's use of the proceeds from the
Securities or for monies paid over to the Company pursuant to the Indenture.

         SECTION 6.5. NOTICE OF DEFAULTS. If a Default occurs and is continuing
with respect to the Securities of any series and if it is known to a Responsible
Officer of the Trustee, the Trustee shall, within 90 days after it occurs,
transmit, in the manner and to the extent provided in Section 313(c) of the
Trust Indenture Act, notice of all uncured Defaults known to it; provided,
however, that, except in the case of a Default in payment on the Securities of
any series, the Trustee may withhold the notice if and so long as a Responsible
Officer in good faith determines that withholding such notice is in the
interests of Holders of Securities of that series; provided, further, that in
the case of any default or breach of the character specified in Section 5.1(3)
with respect to the Securities and coupons of such series, no such notice to
Holders shall be given until at least 90 days after the occurrence thereof.

         SECTION 6.6. REPORTS BY TRUSTEE TO HOLDERS. (a) Within 60 days after
each May 15 of each year commencing with the first May 15 after the first
issuance of Securities pursuant to this Indenture, the Trustee shall transmit by
mail to all Holders of Securities as provided in Section 313(c) of the Trust
Indenture Act a brief report dated as of such May 15 if required by and in
compliance with Section 313(a) of the Trust Indenture Act. A copy of each report
shall, at the time of such transmission to Holders, be filed by the Trustee with
each stock exchange, if any, upon which the Securities are listed, with the
Commission and with the Company. The Company will promptly notify the Trustee
when the Securities are listed on any stock exchange and of any delisting
thereof.

                  (b)      The Trustee shall from time to time transmit by mail
to all Holders of Securities as provided in Section 313(c) of the Trust
Indenture Act, such reports as are required to be filed pursuant to Section
313(b) of the Trust Indenture Act.

         SECTION 6.7. SECURITY HOLDER LISTS. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders of Securities of each series. If the
Trustee is not the Registrar, the Company shall furnish to the Trustee
semiannually on or before the last day of June and December in each year, and at
such other times as the Trustee may request in writing, a list, in such form and
as of such date as the Trustee may reasonably require, containing all the
information in the possession or control of the Registrar, the Company or any of
its Paying Agents other than the Trustee as to the names and addresses of
Holders of Securities of each such series. If there are Bearer Securities of any
series Outstanding, even if the Trustee is the Registrar, the Company shall
furnish to the Trustee such a list containing such information with respect to
Holders of such Bearer Securities only.

                                       52
<PAGE>

         SECTION 6.8. COMPENSATION AND INDEMNITY. (a) The Company shall pay to
the Trustee from time to time such reasonable compensation for its services as
the Company and the Trustee may agree in writing from time to time. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable expenses, disbursements and advances incurred by it
in connection with the performance of its duties under this Indenture, except
any such expense, disbursement or advance as may be attributable to its
negligence or bad faith. Such expenses shall include the reasonable compensation
and expenses of the Trustee's agents and counsel.

                  (b)      The Company shall indemnify the Trustee for, and hold
it harmless against, any and all loss, liability, damage, claim or expense
(including attorneys' fees and expenses, and including taxes other than taxes
based upon, measured by or determined by the income of the Trustee), including
without limitation the costs and expenses of defending itself against any
third-party claim (whether asserted by any Holder or any other Person (other
than the Company to the extent of any claim brought by it against the Trustee
that establishes a breach by the Trustee in the observance or performance of its
duties under this Indenture)), incurred by it without negligence, willful
misconduct or bad faith arising out of or in connection with its acceptance or
administration of the trust or trusts hereunder, including the performance of
its duties or the exercise of its powers hereunder (collectively, "Claims"). The
Trustee shall notify the Company promptly of any Claim (other than Claims made
by the Company against the Trustee) for which it may seek indemnity. The Company
may elect to defend the Claim and, in such case, the Trustee shall cooperate in
the defense. The Trustee may have separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel. The Company need not pay for any
settlement made without its consent.

                  (c)      The Company need not reimburse any expense,
disbursement or advance or indemnify against any Claim incurred by the Trustee
through negligence, willful misconduct or bad faith on the part of the Trustee.

                  (d)      To secure the payment obligations of the Company
pursuant to this Section, the Trustee shall have a lien prior to the Securities
of any series on all money or property held or collected by the Trustee, except
that held in trust to pay principal, premium, if any, and interest on particular
Securities.

                  (e)      When the Trustee incurs expenses or renders services
in connection with an Event of Default specified in Section 5.1(4) or Section
5.1(5), 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.

                  (f)      The provisions of this Section shall survive the
termination of this Indenture.

                  (g)      The protections, agreements and indemnities afforded
to the Trustee under this Section shall include any other agency to which it may
be appointed or with respect to which it may serve hereunder, or in respect of
any Securities under any related Board Resolution or

                                       53
<PAGE>

supplemental indenture, including but not limited to registrar, paying agent,
conversion agent or calculation agent.

         SECTION 6.9. SEPARATE TRUSTEE; REPLACEMENT OF TRUSTEE. (a) The Company
may, but need not, appoint a separate Trustee for any one or more series of
Securities. The resignation or removal of the Trustee and the appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in Section 6.10. In the event of an
appointment of a separate Trustee for any one or more series of Securities, the
allocation of responsibilities between the separate Trustees shall be determined
at that time.

                  (b)      The Trustee may resign at any time with respect to
the Securities of any one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.10 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

                  (c)      The Holders of a majority in aggregate principal
amount of the Outstanding Securities of any series may remove the Trustee with
respect to any one or more series by so notifying the Trustee and the Company in
writing and may appoint a successor Trustee for such series with the Company's
consent. If an instrument of acceptance by a successor Trustee required by
Section 6.10 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of removal, the Trustee being removed may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

                  (d)      If at any time:

                           (1)      the Trustee fails to comply with Section
                                    310(b) of the Trust Indenture Act after
                                    written request therefor by the Company or
                                    by any Holder who has been a bona fide
                                    Holder of a Security for at least six
                                    months, or

                           (2)      the Trustee shall cease to be eligible under
                                    Section 6.11 hereof or Section 310(a) of the
                                    Trust Indenture Act and shall fail to resign
                                    after written request therefor by the
                                    Company or by any Holder of a Security who
                                    has been a bona fide Holder of a Security
                                    for at least six months; or

                           (3)      the Trustee becomes incapable of acting, is
                                    adjudged a bankrupt or an insolvent or a
                                    receiver or public officer takes charge of
                                    the Trustee or its property or affairs for
                                    the purpose of rehabilitation, conservation
                                    or liquidation, then, in any such case, (i)
                                    the Company may remove the Trustee with
                                    respect to all Securities, or (ii) subject
                                    to Section 315(e) of the Trust Indenture
                                    Act, any Holder who has been a bona fide
                                    Holder of a Security for at least

                                       54
<PAGE>

                                    six months may, on behalf of himself and all
                                    others similarly situated, petition any
                                    court of competent jurisdiction for the
                                    removal of the Trustee with respect to all
                                    Securities and the appointment of a
                                    successor Trustee or Trustees.

                  (e)      If the Trustee resigns or is removed or becomes
incapable of acting or if a vacancy exists in the office of Trustee for any
reason, with respect to Securities of one or more series, the Company shall
promptly appoint a successor Trustee with respect to the Securities of that or
those series (it being understood that any such successor Trustee may be
appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 6.10. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.10, become the
successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.10, then, subject to Section 315(e) of the Trust Indenture
Act, any Holder who has been a bona fide Holder of a Security of such series for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

         SECTION 6.10. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) In case of
the appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment.
Thereupon, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee, without further act, deed or conveyance,
shall become vested with all the rights, powers and duties of the retiring
Trustee; but, on the request of the Company or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder.

                  (b)      In case of the appointment hereunder of a successor
Trustee with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and such successor Trustee shall execute and
deliver an indenture supplemental hereto wherein such successor Trustee shall
accept such appointment and which (i) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, such
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, (ii) 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 (iii) shall add to or

                                       55
<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, it being understood that nothing herein or in such supplemental
indenture shall constitute such Trustees co-trustees of the same trust and that
each such Trustee shall be trustee of a trust or trusts hereunder separate and
apart from any trust or trusts hereunder administered by any other such Trustee
and upon the execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on
request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

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

                  (d)      The Company shall give, or cause to be given, 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 in the manner provided for notices to
the Holders of Securities in Section 1.6. 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 6.11. ELIGIBILITY; DISQUALIFICATION. There shall at all times
be a Trustee hereunder with respect to each series of Securities (which need not
be the same Trustee for all series). Each Trustee hereunder shall be eligible to
act as trustee under Section 310(a)(1) of the Trust Indenture Act and shall have
a combined capital and surplus of at least $100,000,000. If such corporation
publishes reports of condition at least annually, pursuant to law or the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article. 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.

         SECTION 6.12. 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 or acquiring all or substantially all of the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the

                                       56
<PAGE>

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, or by succession to or acquisition of all or substantially all
of the corporate trust business of, such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

         SECTION 6.13. APPOINTMENT OF AUTHENTICATING AGENT. The Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue exchange,
registration of transfer or partial redemption thereof, 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. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which instrument shall
be promptly furnished to the Company. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and, except as may otherwise be provided pursuant to
Section 3.1, shall at all times be a bank or trust company or corporation
organized and doing business and in good standing under the laws of the United
States of America or of any State or the District of Columbia, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus
of not less than $1,500,000 and subject to supervision or examination by Federal
or State authorities. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or the requirements of the
aforesaid 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. In case 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 or acquiring the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to
be an Authenticating Agent, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or
further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be

                                       57
<PAGE>

acceptable to the Company and shall give notice of such appointment to all
Holders of Securities of the series with respect to which such Authenticating
Agent will serve in the manner set forth in Section 1.6. 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 herein. No
successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section. The Company agrees to pay to each Authenticating
Agent from time to time such reasonable compensation as the Company and such
Authenticating Agent agree in writing from time to time including reimbursement
of its reasonable expenses 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 or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:
This is one of the [Securities] [of the series designated herein and] referred
to in the within-mentioned Indenture.

                          ________________________, as Trustee

                          By __________________________

                  CONSOLIDATION, MERGER OR SALE BY THE COMPANY

         SECTION 7.1. CONSOLIDATION, MERGER OR SALE OF ASSETS. The Company may
not merge or consolidate with or into any other Person, in a transaction in
which it is not the surviving corporation, or sell, convey, transfer or
otherwise dispose of all or substantially all of its assets to any Person,
unless (i) surviving or transferee Person is organized and existing under the
laws of the United States or a State thereof and such Person expressly assumes
by supplemental indenture all the obligations of the Company under the
Securities and any coupons appertaining thereto and under this Indenture, (ii)
immediately thereafter, giving effect to such merger or consolidation, or such
sale, conveyance, transfer or other disposition, no Default or Event of Default
shall have occurred and be continuing and (iii) the Company shall have delivered
to the Trustee an Officers' Certificate and an Opinion of Counsel each stating
that such merger, consolidation, sale, conveyance, transfer or other disposition
complies with this Article and that all conditions precedent herein provided for
relating to such transaction have been complied with. In the event of the
assumption by a successor Person of the obligations of the Company, such
successor Person shall succeed to and be substituted for the Company hereunder
and under the Securities and any coupons appertaining thereto and all such
obligations of the Company shall terminate.

                                    to the Company and the assumption by any
                                    such successor of the covenants and
                                    obligations of the Company herein and in the
                                    Securities (with such changes herein and
                                    therein as may be necessary or advisable to
                                    reflect such Person's legal status, if such
                                    Person is not a corporation); or

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

                                    qualification of this Indenture under the
                                    Trust Indenture Act or otherwise; or

                                    of any series as permitted by Sections 2.1

                                    electronic or other medium, including
                                    without limitation by computer diskette; or

                           (11)     to evidence and provide for the acceptance
                                    of appointment hereunder by a successor or
                                    separate Trustee with respect to the
                                    Securities of one or more series and/or to
                                    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, pursuant to the requirements of
                                    Article VI; or

                           (12)     if allowed without penalty under applicable
                                    laws and regulations, to permit payment in
                                    the United States (including any of the

                                    territories, its possessions and other areas
                                    subject to its jurisdiction of principal,
                                    premium, if any, or interest, if any, on
                                    Bearer Securities or coupons, if any; or

                           (13)     to correct or supplement any provision
                                    herein which may be inconsistent with any
                                    other provision herein or to cure any
                                    ambiguity or omission or to correct any
                                    mistake; or

                           (14)     to make any other provisions with respect to
                                    matters or questions arising under this
                                    Indenture, provided such action shall not
                                    adversely affect the interests of the
                                    Holders of Securities of any series in any
                                    material respect.

         SECTION 8.2. WITH CONSENT OF HOLDERS. Without prior notice to any
Holder but with the written consent of the Holders of a majority of the
aggregate principal amount of the Outstanding Securities of each series
adversely affected by such supplemental indenture (with the Securities of each
series voting as a class), the Company and the Trustee may enter into an
indenture or indentures supplemental hereto to add any provisions to or to
change or eliminate any provisions of this Indenture or of any other indenture
supplemental hereto or to modify the rights of the Holders of Securities of each
such series; provided, however, that without the consent of the Holder of each
Outstanding Security adversely affected thereby, a supplemental indenture under
this Section may not:

                           (1)      change the Stated Maturity of the principal
                                    of, or any installment of principal of or

                                    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 Indexed Security that
                                    would be due and payable upon a declaration
                                    of acceleration of the Maturity thereof
                                    pursuant to Section 5.2, or change any Place
                                    of Payment where, or the coin or currency in
                                    which any Securities or any premium or the
                                    interest thereon is payable, or impair the
                                    right to institute suit for the enforcement
                                    of any such payment on or after the Stated
                                    Maturity thereof (or, in the case of
                                    redemption, on or after the Redemption
                                    Date);

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

                           (3)      except to the extent provided in Section
                                    8.1(11), make any change in Section 5.7 or
                                    this 8.2 except to increase any percentage
                                    or to provide that certain other provisions
                                    of this Indenture cannot be modified or
                                    waived except with the consent of the
                                    Holders of each Outstanding Security
                                    affected thereby, provided, however, that
                                    this clause shall not be deemed to require
                                    the consent of any Holders with respect to
                                    changes in the references to the "Trustee"
                                    and concomitant changes in this Section, in
                                    accordance with the requirements of Sections
                                    6.10(b) and 8.1(11);

                           (4)      release any guarantors from their guarantees
                                    of the Securities, or, except as
                                    contemplated in any supplemental indenture,
                                    make any change in a guarantee of a Security
                                    that would adversely affect the interests of
                                    the Holders; or

                           (5)      modify the ranking or priority of the
                                    Securities.

For the purposes of this Section 8.2, if the Securities of any series are
issuable upon the exercise of warrants, any holder of an unexercised and
unexpired warrant with respect to such series shall not be deemed to be a Holder
of Outstanding Securities of such series in the amount issuable upon the
exercise of such warrants.

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

                                       61
<PAGE>

         It is not necessary under this Section 8.2 for the Holders to consent
to the particular form of any proposed supplemental indenture, but it is
sufficient if they consent to the substance thereof.

         SECTION 8.3. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to
this Indenture or the Securities of one or more series shall be set forth in a
supplemental indenture that complies with the Trust Indenture Act as then in
effect.

         SECTION 8.4. EXECUTION OF SUPPLEMENTAL INDENTURES. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which adversely affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise. The Trustee shall enter into any such
supplemental indenture presented to it by the Company in compliance with this
Article 8 if such supplemental indenture does not adversely affect the Trustee's
own rights, duties or immunities under this Indenture or otherwise. In
formulating its opinion on such matters the Trustee shall be entitled to rely on
such evidence as it deems appropriate, which may be or include, without
limitation, reliance solely on an opinion or advice of its counsel.

         SECTION 8.5. 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 and of any coupon appertaining
thereto shall be bound thereby; provided that if such supplemental indenture
makes any of the changes described in clauses (1) through (4) of the first
proviso to Section 8.2, such supplemental indenture shall bind each Holder of a
Security who has consented to it and every subsequent Holder of such Security or
any part thereof.

         SECTION 8.6. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.
Securities, including any coupons, of any series authenticated and delivered
after the execution of any supplemental indenture pursuant to this Article may,
and shall if required by the Trustee, bear a notation in form approved by the
Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities including any coupons of any series
so modified as to conform, in the opinion of the Trustee and the Company, to any
such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities including any coupons of such series.

                                   ARTICLE IX

                                    COVENANTS

         SECTION 9.1. PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST. The
Company covenants and agrees for the benefit of the Holders of each series of
Securities

                                       62
<PAGE>

that it will duly and punctually pay the principal of, premium, if any, and
interest on the Securities of that series in accordance with the terms of the
Securities of such series, any coupons appertaining thereto and this Indenture.
An installment of principal, premium, if any, or interest shall be considered
paid on the date it is due if the Trustee or Paying Agent holds on that date
money designated for and sufficient to pay the installment.

         SECTION 9.2. MAINTENANCE OF OFFICE OR AGENCY. If Securities of a series
are issued as Registered Securities, the Company will maintain in each Place of
Payment for any series of Securities an office or agency where Securities of
that series may be presented or surrendered for payment, where Securities of
that series may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company will maintain, (i) subject to any
laws or regulations applicable thereto, an office or agency in a Place of
Payment for that series which is located outside the United States, where
Securities of that series and related coupons may be presented and surrendered
for payment; provided, however, that if the Securities of that series are listed
on The International Stock Exchange of the United Kingdom and the Republic of
Ireland Limited, the Luxembourg Stock Exchange or any other stock exchange
located outside the United States and such stock exchange shall so require, the
Company will maintain a Paying Agent for the Securities of that series in
London, Luxembourg or any other required city located outside the United States,
as the case may be, so long as the Securities of that series are listed on such
exchange, and (ii) subject to any laws or regulations applicable thereto, an
office or agency in a Place of Payment for that series which is located outside
the United States where Securities of that series may be surrendered for
exchange and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and any change in the
location, of any such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, except that
Bearer Securities of that series and the related coupons unless otherwise
specified in the Supplemental Indenture for such Series, may be presented and
surrendered for payment and conversion at the offices specified in the Security,
in London, England, and the Company hereby appoints the Trustee as its agent to
receive all such presentations, surrenders, notices and demands (provided,
however, that the foregoing appointment shall not impose or imply any obligation
on the part of the Trustee to maintain any office for any such purposes other
than the Corporate Trust Office.)

         Unless otherwise specified as contemplated by Section 3.1, no payment
of principal, premium or interest on Bearer Securities shall be made at any
office or agency of the Company in the United States, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or coupon for payment, even if the payment would be credited to an
account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium or interest on any such Bearer Security shall be
made at an office of a Paying Agent of the Company in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or interest, as the case may be, at all offices or
agencies

                                       63
<PAGE>

outside the United States maintained for the purpose by the Company in
accordance with this Indenture is illegal or effectively precluded by exchange
controls or other similar restrictions.

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

         Unless otherwise specified as contemplated by Section 3.1, the Trustee
shall initially serve as Paying Agent. The Paying Agent may make reasonable
rules not inconsistent herewith for the performance of its functions.

         SECTION 9.3. MONEY FOR SECURITIES TO BE HELD IN TRUST; UNCLAIMED MONEY.
If the Company shall at any time act as its own Paying Agent with respect to any
series of Securities, it will, on or before each due date of the principal of,
premium, if any, or interest on any of the Securities of that series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal, premium, if any, or interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee in writing of any failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of any failure so to act.
If the Company is not acting as its own Paying Agent, the Company will cause
each Paying Agent for any series of Securities other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will:

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

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

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

                                       64
<PAGE>

                                    in this Section 9.3 to the contrary, the
                                    Company may at any time, for the purpose of
                                    obtaining the satisfaction and discharge of
                                    this Indenture, or with respect to one or
                                    more series of Securities, or for any other
                                    purpose, pay, or by Company Order direct any
                                    Paying Agent to pay, to the Trustee all sums
                                    held in trust by the Company or such Paying
                                    Agent, such sums to be held by the Trustee
                                    upon the same trusts as those upon which
                                    such sums were held by the Company or such
                                    Paying Agent; and, upon such payment by any
                                    Paying Agent to the Trustee, such Paying
                                    Agent shall be released from all further
                                    liability with respect to such money.

         Subject to applicable abandoned property laws, any money deposited with
the Trustee or any Paying Agent, or then held by the Company, in trust for the
payment of any principal, premium or interest or other amounts on any Security
of any series and remaining unclaimed for two years after such principal,
premium, if any, or interest or other amounts has become due and payable shall
be paid to the Company (including interest income on such funds, if any), or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security and coupon, if any, shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

         SECTION 9.4. CORPORATE EXISTENCE. Subject to Article VII, the Company
will at all times do or cause to be done all things necessary to preserve and
keep in full force and effect its corporate existence.

         SECTION 9.5. MAINTENANCE OF PROPERTIES. The Company will cause all
material properties used or useful in the conduct of its business to be

with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as (and to the
extent) in the judgment of the Company may be necessary or appropriate in
connection with its business; provided, however, that nothing in this Section
shall prevent the Company from discontinuing the operation or maintenance of any
of such properties if such discontinuance is, in the judgment of the Company,
desirable in the conduct of its business and not disadvantageous in any material
respect to the Holders.

         SECTION 9.6. REPORTS BY THE COMPANY. The Company covenants, at any time
at which there are Outstanding Securities of any series issued under this
Indenture:

                  (a)      to file with the Trustee, within 30 days after the

rules and regulations prescribe) which the Company may be required to file with
the Commission pursuant to section 13 or section 15(d) of the Securities
Exchange Act of 1934, as amended; or, if the Company is not required to file

regulations prescribed from time to time by the Commission, such of the
supplementary and periodic information, documents and reports which

                                       65

accordance with the rules and regulations prescribed from time to time by the
Commission, such additional information, documents and reports with respect to
compliance by the Company with the conditions and covenants provided for in this
Indenture, as may be required from time to time by such rules and regulations;
and

                  (c)      to transmit to all Holders of Securities within 30
days after the filing thereof with the Trustee, in the manner and to the extent
provided in section 313(c) of the Trust Indenture Act, such summaries of any
information, documents and reports required to be filed by the Company pursuant
to subsections (a) and (b) of this Section 9.6, as may be required by rules and
regulations prescribed from time to time by the Commission.

         SECTION 9.7. ANNUAL REVIEW CERTIFICATE. At any time at which there are
Outstanding Securities of any series issued under this Indenture, the Company
covenants and agrees to deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company, a brief certificate from the principal
executive officer, principal financial officer, or principal accounting officer

after the Company shall have received notice that the same has become delinquent
(1) all material taxes, assessments and governmental charges levied or imposed
upon the Company or any Subsidiary or upon the income, profits or property of
the Company or any Subsidiary, and (2) all lawful claims for labor, materials
and supplies which, if unpaid, might by law become a material lien upon the
property of the Company or any Subsidiary; provided, however, that the Company
shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings; provided, further,
that the Company shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim unless the failure to
pay or discharge such tax, assessment, charge or claim would, individually or in
the aggregate with all such failures, have a material adverse effect on the
Company and its Subsidiaries taken as a whole.

                                   REDEMPTION

         SECTION 10.1. APPLICABILITY OF ARTICLE. Securities (including coupons,
if any) of or within any series which are redeemable in whole or in part before
their Stated Maturity shall be redeemable in accordance with their terms and
(except as otherwise specified

                                       66
<PAGE>

in the applicable Board Resolution or supplemental indenture with respect to
such Series of Securities, as contemplated by Section 3.1 for Securities of any
series) in accordance with this Article.

         SECTION 10.2. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of
the Company to redeem any Securities, including coupons, if any, shall be
evidenced by a Board Resolution. In the case of any redemption at the election
of the Company of less than all the Securities or coupons, if any, of any series
of the same tenor, the Company shall, at least 60 days (45 days in the case of
redemption of all Securities of any series or of any series with the same (i)
Stated Maturity, (ii) period or periods within which, price or prices at which
and terms and conditions upon which such Securities may or shall be redeemed or
purchased, in whole or in part, at the option of the Company or pursuant to any
sinking fund or analogous provision or repayable at the option of the Holder and
(iii) rate or rates at which the Securities bear interest, if any, or formula
pursuant to which such rate or rates accrue (collectively, the "Equivalent
Principal Terms")) prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture or (ii) pursuant to an election of the Company which
is subject to a condition specified in the terms of such Securities, the Company
shall furnish the Trustee with an Officers' Certificate evidencing compliance
with such restriction or condition.

         SECTION 10.3. SELECTION OF SECURITIES TO BE REDEEMED. If less than all
the Securities with Equivalent Principal Terms of any series are to be redeemed
(unless all of the Securities of such series and of a specified tenor are to be
redeemed), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum authorized
denomination for Securities (including coupons, if any) of that series with
Equivalent Principal Terms or any integral multiple thereof) of the principal
amount of Securities (including coupons, if any) of such series with Equivalent
Principal Terms of a denomination larger than the minimum authorized
denomination for Securities of that series. Unless otherwise provided in the
terms of a particular series of Securities, the portions of the principal of
Securities so selected for partial redemption shall be equal to the minimum
authorized denomination of the Securities of such series, or an integral
multiple thereof, and the principal amount which remains outstanding shall not
be less than the minimum authorized denomination for Securities of such series.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed. If the
Securities (including coupons, if any) of a series having different issue dates,
interest rates and maturities (whether or not originally issued in a Periodic
Offering) are to be redeemed, the Company in its discretion may select the
particular Securities or portions thereof to be redeemed and shall notify the
Trustee thereof by such time prior to the relevant redemption date or dates as
the Company and the Trustee may agree.

                                       67
<PAGE>

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

         SECTION 10.4. NOTICE OF REDEMPTION. Unless otherwise specified as
contemplated by Section 3.1, notice of redemption shall be given by first-class
mail, postage prepaid, mailed not less than 30 days nor more than 60 days prior
to the Redemption Date, unless a shorter period is specified in the Securities
to be redeemed, to each Holder of the Securities to be redeemed.

         All notices of redemption shall state:

                           (1)      the Redemption Date;

                           (2)      the Redemption Price and the amount of
                                    accrued interest, if any, to be paid;

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

                           (4)      in case any Security is to be redeemed in
                                    part only, the notice which relates to such
                                    Security shall state that on and after the
                                    Redemption Date, upon surrender of such
                                    Security, the Holder of such Security will
                                    receive, without a charge, a new Security or
                                    Securities of authorized denominations for
                                    the principal amount thereof remaining
                                    unredeemed;

                           (5)      the Place or Places of Payment where such
                                    Securities are to be surrendered for payment
                                    for the Redemption Price;

                           (6)      that Securities of the series called for
                                    redemption and all unmatured coupons, if
                                    any, appertaining thereto must be
                                    surrendered to the Paying Agent to collect
                                    the Redemption Price;

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

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

                           (9)      that, unless otherwise specified in such
                                    notice, Bearer Securities of any series, if
                                    any, surrendered for redemption must be
                                    accompanied by all coupons maturing
                                    subsequent to the

                                       68
<PAGE>

                                    Redemption Date or the amount of any such
                                    missing coupon or coupons will be deducted
                                    from the Redemption Price, unless security
                                    or indemnity satisfactory to the Company,
                                    the Trustee and any Paying Agent is
                                    furnished;

                           (10)     if Bearer Securities of any series are to be
                                    redeemed and any Registered Securities of
                                    such series are not to be redeemed and if
                                    such Bearer Securities may be exchanged for
                                    Registered Securities not subject to
                                    redemption on this Redemption Date pursuant
                                    to Section 3.5 or otherwise, the last date,
                                    as determined by the Company, on which such
                                    exchanges may be made; and

                           (11)     the CUSIP number, if any, of such
                                    Securities. Notice of redemption of
                                    Securities to be redeemed at the election of
                                    the Company shall be given by the Company
                                    or, at the Company's request, by the Trustee
                                    in the name and at the expense of the
                                    Company (provided that the Company prepare
                                    and provide to the Trustee the form of such
                                    notice, or, if acceptable to the Trustee,
                                    provides sufficient information to enable
                                    the Trustee to prepare such notice, in each
                                    case on a timely basis.)

         SECTION 10.5. DEPOSIT OF REDEMPTION PRICE. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 9.3) an amount of money in the currency or
currencies (including currency units or composite currencies) in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay on the
Redemption Date the Redemption Price of, and (unless the Redemption Date shall
be an Interest Payment Date) interest accrued to the Redemption Date on, all
Securities or portions thereof which are to be redeemed on that date.

         Unless any Security by its terms prohibits any sinking fund payment
obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

         SECTION 10.6. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest and the coupons for any such interest
appertaining to any Bearer Security so to be redeemed, except to the extent
provided below, shall be void and such Securities shall cease from and after the
Redemption Date to be entitled to any benefit or security under this Indenture,
and the Holders thereof shall have no right in respect of such Securities except
the right to receive the Redemption Price thereof and unpaid interest to the
Redemption Date. Except as provided in the next succeeding paragraph,

                                       69
<PAGE>

upon surrender of any such Security, including coupons, if any, for redemption
in accordance with said notice, such Security shall be paid by the Company at
the Redemption Price, together with accrued interest, if any, to the Redemption
Date; provided, however, that unless otherwise specified as contemplated by
Section 3.1, installments of interest on Bearer Securities whose Stated Maturity
is on or prior to the Redemption Date and the principal of, and premium, if any,
on such Bearer Securities shall be payable only at an office or agency located
outside the United States and it possessions (except as otherwise provided in
Section 9.2) and, unless otherwise specified as contemplated by Section 3.1,
only upon presentation and surrender of coupons for such interest; and provided,
further, that, unless otherwise specified as contemplated by Section 3.1,
installments of interest on Registered Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of
business on the relevant Record Dates according to their terms and the
provisions of Section 3.7.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Bearer Security may be paid after deducting from the Redemption Price an amount
equal to the face amount of all such missing coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only at
an office or agency located outside of the United States (except as otherwise
provided pursuant to Section 9.2) and, unless otherwise specified as
contemplated by Section 3.1, only upon presentation and surrender of those
coupons.

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

         SECTION 10.7. SECURITIES REDEEMED IN PART. Upon surrender of a Security
that is redeemed only in part at any Place of Payment therefor (with, if the
Company or the Trustee so require, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing), the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of
that Security, without service charge, a new Security or Securities of the same
series, having the same form, terms and Stated Maturity, in any authorized
denomination equal in aggregate principal amount to the unredeemed portion of
the principal amount of the Security surrendered.

                                  SINKING FUNDS

         SECTION 11.1. APPLICABILITY OF ARTICLE. The provisions of this Article
shall be applicable to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 3.1 for
Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 11.2. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

         SECTION 11.2. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.
The Company (i) may deliver Outstanding Securities of a series (other than any
previously called for redemption) together, in the case of Bearer Securities of
such series, with all unmatured coupons appertaining thereto and (ii) may apply
as a credit Securities of a series which have been redeemed either at the
election of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any sinking
fund payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

         SECTION 11.3. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than
60 days prior to each sinking fund payment date for any series of Securities,
the Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing sinking fund payment for that series pursuant to the
terms of that series, the portion thereof, if any, which is to be satisfied by
payment of cash and the portion thereof, if any, which is to be satisfied by
delivering and crediting Securities of that series pursuant to Section 11.2 and
will also deliver to the Trustee any Securities to be so delivered. Not less
than 30 days before each such sinking fund payment date the Trustee shall select
the Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 10.3 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 10.4. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
10.6 and 10.7.
