complied with, except that in the case of any such application or request

                                       10
<PAGE>   20
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
Section 1005) shall include:

                  (1) a statement that each individual signing such certificate
         or opinion has read such condition or covenant and the definitions
         herein relating thereto;

                  (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 each such
         individual, such condition or covenant has been complied with.

                  Section 103 Form of Documents Delivered to Trustee.

                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion as 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 an Opinion of Counsel, or a
certificate or representations by counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the opinion, certificate or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such Opinion of Counsel or certificate or
representations 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 as to such factual matters is in the
possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
as to such matters are erroneous.

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

                  SECTION 104 Acts of Holders.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed (which may be electronically signed) by such
Holders in person or by agents duly appointed in writing. If Securities of a
series are issuable as Bearer Securities, any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and conclusive
in favor of the Trustee and the Company and any agent of the Trustee or the
Company, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities shall be proved in the manner provided in
Section 1506.

                  (b) The fact and date of the execution of any such instrument
or writing, or the authority of the Person executing the same, may be proved in
any manner which the Trustee deems reasonably sufficient.

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

                  (d) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depositary, by any trust company, bank, banker or other depositary, 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
depositary, 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 (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner that the Trustee deems
sufficient.

<PAGE>   22
                  (e) If the Company shall solicit from the Holders of
Registered Securities any request, demand, authorization, direction, notice,
consent, waiver or other Act, the Company may, at its option, in or pursuant to
a Board Resolution, fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.

                  Notwithstanding TIA Section 316(c), such record date shall be
the record date specified in or pursuant to such Board Resolution, which shall
be a date not earlier than the date 30 days prior to the first solicitation of
Holders generally in connection therewith and not later than the date such
solicitation is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities 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 it shall become effective pursuant
to the provisions of this Indenture not later than 180 days after the record
date.

                  (f) 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, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

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

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with, (1) the
Trustee by any Holder or by the Company shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing to or with the Trustee
at its Corporate Trust Office, Attention: Corporate Trust Administration, or at
any other address previously furnished in writing by the Trustee to the Holders
or the Company 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, given, furnished or filed with or to the
Company addressed to it at the address of its principal office specified in the
first paragraph of this Indenture or at any other address previously furnished
in writing to the Trustee by the Company.

                  SECTION 106 Notice to Holders; Waiver.

                                       13
<PAGE>   23
                  Where this Indenture provides for notice of any event to
Holders of Registered Securities by the Company or the Trustee, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, or by email, to each such
Holder affected by such event, at his physical address or email address as such
address appears in the Security Register, not later than the latest date, and
not earlier than the earliest date, prescribed for the giving of such notice. In
any case where notice to Holders of Registered Securities 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. 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 or irregularities in regular
mail service or by reason of any other cause it shall be impracticable to give
such notice by mail, then such notification to Holders of Registered Securities
as shall be made with the approval of the Trustee shall constitute a sufficient
notification to such Holders for every purpose hereunder.

                  Except as otherwise expressly provided herein or otherwise
specified with respect to any Securities pursuant to Section 301, where this
Indenture provides for notice to Holders of Bearer Securities of any event, such
notice shall be sufficiently given if published in (1) an Authorized Newspaper
in The City of New York and in such other city or cities as may be specified in
such Securities on a Business Day, or (2) an electronic medium easily accessible
by the Holders as may be specified to such Holders, such publication to be not
later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice. Any such notice shall be deemed to have been
given on the date of such publication or, if published more than once, on the
date of the first such publication.

                  If by reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause it
shall be impracticable to publish any notice to Holders of Bearer Securities as
provided above, then such notification to Holders of Bearer Securities as shall
be given with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder. Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, 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 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 the
equivalent of such notice. Waivers of notice by Holders shall be filed

                                       14
<PAGE>   24
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 107 Effect of Headings and Table of Contents.

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

                  SECTION 108 Successors and Assigns.

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

                  SECTION 109 Separability Clause.

                  In case any provision in this Indenture or in any Security or
coupon 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 110 Benefits of Indenture.

                  Nothing in this Indenture or in the Securities or coupons,
express or implied, shall give to any Person, other than the parties hereto, any
Security Registrar, any Paying Agent, any Authenticating Agent and their
successors hereunder and the Holders any benefit or any legal or equitable
right, remedy or claim under this Indenture.

                  SECTION 111 Governing Law.

                  This Indenture and the Securities and coupons shall be
governed by and construed in accordance with the law of the State of New York
without regard to principles of conflicts of laws. This Indenture is subject to
the provisions of the Trust Indenture Act that are required to be part of this
Indenture and shall, to the extent applicable, be governed by such provisions.

                  SECTION 112 Legal Holidays.

                  In any case where any Interest Payment Date, Redemption Date,
Repayment Date, sinking fund payment date, Stated Maturity or Maturity 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
other than a provision in the Securities of any series which specifically states
that such provision shall apply in lieu of this Section), payment of principal
(or premium, if any) or interest, if any, need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date, Redemption Date, Repayment Date or sinking fund payment date, or
at the Stated Maturity or Maturity; provided that no interest shall accrue on
the amount so payable for the period from and after such Interest Payment Date,
Redemption Date,

                                       15
<PAGE>   25
Repayment Date, sinking fund payment date, Stated Maturity or Maturity, as the
case may be.

                  SECTION 113 Conflict of Any Provision of Indenture with Trust
Indenture Act.

                  If and to the extent that any provision of this Indenture
limits, qualifies or conflicts with the duties imposed by TIA Sections 310 to
318, inclusive, or conflicts with any provision (an "incorporated provision")
required by or deemed to be included in this Indenture by operation of such TIA
Sections or any section of the TIA, such imposed duties or incorporated
provisions 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 excluded, as the case may be.

                  SECTION 114 No Recourse against Others.

                  A director, officer, employee or stockholder, as such, of the
Company shall not have any liability for any obligations of the Company under
the Securities or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder by accepting any of
the Securities waives and releases all such liability.

                  SECTION 115 Waiver of Trial by Jury.

                  The Company, Trustee, and Holders hereby irrevocably and
unconditionally waive the right to trial by jury in connection with any claim
arising out of or relating to the Securities and under this Indenture.

                                  ARTICLE TWO

                                SECURITIES FORMS

                  SECTION 201 Forms of Securities.

                  The Registered Securities, if any, of each series and the
Bearer Securities, if any, of each series and related coupons shall be in
substantially the forms as shall be established in one or more indentures
supplemental hereto or approved from time to time by or pursuant to a Board
Resolution in accordance with Section 301, shall have such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture or any indenture supplemental hereto, and may have
such letters, numbers or other marks of identification or designation and such
legends or endorsements placed thereon as the Company may deem appropriate and
as are not inconsistent with the provisions of this Indenture, or as may be
required to comply with any law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the
Securities may be listed, or to conform to usage.

                                       16
<PAGE>   26
                  Unless otherwise specified as contemplated by Section 301,
Bearer Securities shall have interest coupons attached. The definitive
Securities and coupons shall be printed, lithographed or engraved or produced by
any combination of these methods on a steel engraved border or steel engraved
borders or may be produced in any other manner, all as determined by the
officers executing such Securities or coupons, as evidenced by their execution
of such Securities or coupons.

                  SECTION 202 Form of Trustee's Certificate of Authentication.

                  Subject to Section 611, the Trustee's certificate of
authentication shall be in substantially the following form:

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

                  THE BANK OF NEW YORK,
                         as Trustee

                  By:  ___________________________
                         Authorized Signatory

                  SECTION 203 Securities Issuable in Global Form.

                  If Securities of or within a series are issuable in global
form, as specified as contemplated by Section 301, then, notwithstanding clause
(8) of Section 301 and the provisions of Section 302, any such Security shall
represent such of the Outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of Outstanding Securities of such series from time to time endorsed thereon and
that the aggregate amount of Outstanding Securities of such series represented
thereby may from time to time be increased or decreased to reflect exchanges.
Any endorsement of a Security in global form to reflect the amount, or any
increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made by the Trustee in such manner and upon instructions given
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered to the Trustee pursuant to Section 303 or 304. Subject to the
provisions of Section 303 and, if applicable, Section 304, 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. If a Company Order pursuant to Section 303 or 304 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement, delivery or redelivery of a Security in global form
shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

                  The provisions of the last sentence of Section 303 shall apply
to any Security represented by a 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 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the

                                       17
<PAGE>   27
principal amount of Securities represented thereby, together with the written
statement contemplated by the last sentence of Section 303.

                  Notwithstanding the provisions of Section 307, unless
otherwise specified as contemplated by Section 301, payment of principal of (and
premium, if any) and interest, if any, on any Security in permanent global form
shall be made to the Person or Persons specified therein.

                  Notwithstanding the provisions of Section 309 and except as
provided in the preceding paragraph, the Company, the Trustee and any agent of
the Company and the Trustee shall treat as the Holder of such principal amount
of Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a permanent
global Security in bearer form, Euroclear or Clearstream.

                  SECTION 204 Form of Legend for Book-Entry Securities.

                  Any Global Security authenticated and delivered hereunder
shall bear a legend (which would be in addition to any other legends required in
the case of a restricted Security) in substantially the following form:

                  THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE
         INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A
         DEPOSITORY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN
         WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS
         SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY
         PERSON OTHER THAN SUCH DEPOSITORY OR ITS NOMINEE EXCEPT IN THE LIMITED
         CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

                  UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
         REPRESENTATIVE OF THE DEPOSITARY TRUST COMPANY TO THE ISSUER OR ITS
         AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT AND SUCH
         CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE IS REGISTERED IN
         THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS REQUESTED BY AN AUTHORIZED
         REPRESENTATIVE OF THE DEPOSITORY, ANY TRANSFER, PLEDGE OR OTHER USE
         HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL, SINCE
         THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

                                 ARTICLE THREE

<PAGE>   28
                  The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is unlimited. The Securities
shall be subordinated in right of payment to Senior Indebtedness as provided in
Article Sixteen. The Securities shall rank equally and pari passu and may be
issued in one or more series. There shall be established in one or more Board
Resolutions or pursuant to authority granted by one or more Board Resolutions
and, subject to Section 303, set forth, or determined in the manner provided, in
an Officers' Certificate, or established in one or more indentures supplemental
hereto, prior to the issuance of Securities of any series, any or all of the
following, as applicable (each of which (except for the matters set forth in
clauses (1), (2) and (15) below), if so provided, may be determined from time to
time by the Company with respect to unissued Securities of the series when
issued from time to time):

                  (1)      the title of the Securities of the series (which
         shall distinguish the Securities of such series from all other series
         of Securities);

                  (2)      any limit upon the aggregate principal amount of the
         Securities of the series that may be authenticated and delivered under
         this Indenture (except for Securities authenticated and delivered upon
         registration of transfer of, or in exchange for, or in lieu of, other
         Securities of the series pursuant to Section 304, 305, 306, 906, 1107
         or 1305) and whether any series may be reopened for additional
         Securities of that series; in the event that such series of Securities
         may be reopened from time to time for issuances of additional
         Securities of such series, the terms thereof shall indicate whether any
         such additional Securities shall have the same terms as the prior
         Securities of such series or whether the Company may establish
         additional or different terms with respect to such additional
         Securities;

                  (3)      the date or dates, or the method by which such date
         or dates will be determined or extended, on which the principal (and
         premium, if any,) of the Securities of the series shall be payable;

                  (4)      the rate or rates at which the Securities of the
         series shall bear interest, if any, or the method by which such rate or
         rates shall be determined, the date or dates from which such interest
         shall accrue or the method by which such date or dates shall be
         determined, the Interest Payment Dates on which such interest will be
         payable and the Regular Record Date, if any, for the interest payable
         on any Registered Security on any Interest Payment Date, or the method
         by which such date shall be determined, and the basis upon which such
         interest shall be calculated if other than that of a 360-day year of
         twelve 30-day months;

                  (5)      the place or places, if any, other than or in
         addition to the Borough of Manhattan, The City of New York, where the
         principal of (and premium, if any) and interest, if any, on Securities

         period or periods within which or the date or dates on which, the price

         premium, if any) or interest, if any, on the Securities of the series
         may be determined with reference to an index, formula or other method

         Currencies in which such Securities are to be paid, in each case in
         accordance with, in addition to or in lieu of any of the provisions of
         Section 312;

                  (14)     provisions, if any, granting special rights to the
         Holders of Securities of the series upon the occurrence of such events
         as may be specified;

                  (15) any deletions from, modifications of or additions to the
         Events of Default or covenants or other provisions (including any
         deletions from, modifications of or additions to any of the provisions
         of Section 1007) of the Company with respect to Securities of the
         series, whether or not such Events of Default or covenants or other
         provisions are consistent with the Events of Default or covenants or
         other provisions set forth herein;

         are to be issuable initially in temporary global form and whether any
         Securities of the series are to be issuable in permanent global form

         interests in any such permanent global Security may exchange such
         interests for Securities of such series in certificated form and of
         like tenor of any authorized form and denomination and the
         circumstances under which any such exchanges may occur, if other than
         in the manner provided in Section 305, and, if Registered Securities of

         depository for such series;

                  (17)     the date as of which any Bearer Securities of the

                  (18)     the Person to whom any interest on any Registered

         whose name such Security (or one or more Predecessor Securities) is

         Section 304;

                  (19)     the applicability, if any, of Sections 1402 and 1403
         to the Securities of the series (and, in the case of Section 1403, if
         applicable, any

                                       21

         additional covenants subject to covenant defeasance) and any provisions
         in modification of, in addition to or in lieu of any of the provisions
         of Article Fourteen;

                  (20)     if the Securities of such series are to be issuable
         in definitive form (whether upon original issue or upon exchange of a
         temporary Security of such series) only upon receipt of certain
         certificates or other documents or satisfaction of other conditions,
         then the form and/or terms of such certificates, documents or

                  (21)     whether, under what circumstances and the Currency in
         which, the Company will pay Additional Amounts as contemplated by
         Section 1005 on the Securities of the series to any Holder who is not a
         United States person (including any modification to the definition of
         such term) in respect of any tax, assessment or governmental charge
         and, if so, whether the Company will have the option to redeem such
         Securities rather than pay such Additional Amounts (and the terms of
         any such option);

                  (22)     the designation of the initial Exchange Rate Agent,
         if any;

                  (23)     if the Securities of the series are to be convertible
         into or exchangeable for any securities of any Person (including the
         Company), the terms and conditions upon which such Securities of the
         series will be so convertible or exchangeable (including, without
         limitation, the initial conversion price or rate, the conversion
         period, the conversion agent, if any, adjustments of the applicable
         conversion price or rate and any requirements with respect to the
         reservation of shares or Securities for purposes of conversion);

                  (24)     whether payment of any amounts due hereunder will be
         guaranteed by one or more guarantors, including subsidiaries of the
         Company; and

                  (25)     any other terms of the series (which terms shall not
         be inconsistent with the requirements of the Trust Indenture Act).

                  All Securities of any one series and the coupons appertaining
to any Bearer Securities of such series shall be substantially identical except,
in the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to such Board Resolution (subject to
Section 303) and set forth in such Officers' Certificate or in any such
indenture supplemental hereto. All Securities of any one series need not be
issued at the same time and, unless otherwise provided, a series may be
reopened, without the consent of the Holders, for issuances of additional
Securities of such series or to establish additional terms of such series of
Securities (which additional terms shall only be applicable to unissued or
additional Securities of such series).

                  If any of the terms of the Securities of any series are
established by action taken pursuant to one or more Board Resolutions, a copy of
an appropriate record of such action(s) shall be certified by the Secretary or
an Assistant Secretary of the Company and

                                       22
<PAGE>   32
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the Securities of such series.

                  SECTION 302 Denominations.

                  The Securities of each series shall be issuable in such
denominations as shall be specified as contemplated by Section 301. In the
absence of any such provision with respect to Securities of any series, the
principal, premium and interest and Additional Amounts with respect to the
Securities shall be payable in Dollars. With respect to Securities of any series
denominated in Dollars, in the absence of any such provisions with respect to
the Securities of any series, the Registered Securities of such series, other
than Registered Securities issued in global form (which may be of any
denomination) shall be issuable in denominations of $1,000 and any integral
multiple thereof, and the Bearer Securities of such series, other than Bearer
Securities issued in global form (which may be of any denomination), shall be
issuable in a denomination of $5,000.

                  SECTION 303 Execution, Authentication, Delivery and Dating.

                  The Securities and any coupons appertaining thereto shall be
executed on behalf of the Company by its Chairman, its President or one of its
Vice Presidents, under its corporate seal reproduced thereon or a facsimile or
copy thereof and attested by its Secretary or one of its Assistant Secretaries.
The signature of any of these officers on the Securities and coupons may be
manual or facsimile signatures of the present or any future such authorized
officer and may be imprinted or otherwise reproduced on the Securities.

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

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities of any series,
together with any coupon appertaining thereto, executed by the Company, to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities either to the Company or
according to the directions contained in the Company Order; provided, however,
that, in connection with its original issuance, no Bearer Security shall be
mailed or otherwise delivered to any location in the United States; and provided
further that, unless otherwise specified with respect to any series of
Securities pursuant to Section 301, a Bearer Security may be delivered in
connection with its original issuance only if the Person entitled to receive
such Bearer Security shall have furnished a certificate in the form set forth in
Exhibit A-1 to this Indenture or such other certificate as may be specified with
respect to any series of Securities pursuant to Section 301, dated no earlier
than 15 days prior to the earlier of the date on which such Bearer Security is
delivered and the date on which any temporary Security first becomes

                                       23
<PAGE>   33
exchangeable for such Bearer Security in accordance with the terms of such
temporary Security and this Indenture. If any Security shall be represented by a
permanent global Bearer Security, then, for purposes of this Section and Section
304, the notation of a beneficial owner's interest therein upon original
issuance of such Security or upon exchange of a portion of a temporary global
Security shall be deemed to be delivery in connection with its original issuance
of such beneficial owner's interest in such permanent global Security. Except as
permitted by Section 306, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have
been detached and cancelled. If all the Securities of any series are not to be
issued at one time and if the Board Resolution or supplemental indenture
establishing such series shall so permit, such Company Order may set forth
procedures acceptable to the Trustee for the issuance of such Securities and
determining the terms of particular Securities of such series, such as interest
rate, maturity date, date of issuance and date from which interest shall accrue.

                  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 TIA Sections 315(a)
through 315(d)) shall be fully protected in relying upon,

                  (i)      an Opinion of Counsel stating, (a) that the form or
         forms of such Securities and any coupons have been established in
         conformity with the provisions of this Indenture; (b) that the terms of
         such Securities and any coupons have been established in conformity
         with the provisions of this Indenture; and (c) that such Securities,
         together with any coupons appertaining thereto, when completed by
         appropriate insertions and executed and delivered by the Company to the
         Trustee for authentication in accordance with this Indenture,
         authenticated and delivered by the Trustee in accordance with this
         Indenture and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute legal,
         valid and binding obligations of the Company, enforceable in accordance
         with their terms, subject to applicable bankruptcy, insolvency,
         reorganization and other similar laws of general applicability relating
         to or affecting the enforcement of creditors' rights, to general
         equitable principles and to such other qualifications as such counsel
         shall conclude do not materially affect the rights of Holders of such
         Securities and any coupons;

                  (ii)     an Officers' Certificate stating, to the best of the
         knowledge of the signers of such certificate, that no Event of Default
         with respect to any of the Securities shall have occurred and be
         continuing;

                  (iii)    an executed supplemental indenture (if any).

                  Notwithstanding the provisions of Section 301 and of this
Section 303, if all the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver an Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order, Opinion of Counsel or
Officers' Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each Security of such series, but

                                       24
<PAGE>   34
such order, opinion and certificates, with appropriate modifications to cover
such future issuances, shall be delivered at or before the time of issuance of
the first Security of such series. If such form or terms have been so
established, the Trustee shall not be required to authenticate such Securities
if the issue of such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties, obligations or immunities under the Securities and
this Indenture or otherwise in a manner which is not reasonably acceptable to
the Trustee. Notwithstanding the generality of the foregoing, the Trustee will
not be required to authenticate Securities denominated in a Foreign Currency if
the Trustee reasonably believes that it would be unable to perform its duties
with respect to such Securities. 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 301.

                  No Security or coupon shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose unless there appears on
such Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee or an Authenticating Agent by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.

                  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 310 together with a written statement (which need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel) stating
that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

                  SECTION 304 Temporary Securities.

                  (a)      Pending the preparation of definitive Securities of
any series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form, or, if authorized, in bearer form with one or
more coupons or without coupons, 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. In the case of Securities of any series, such temporary Securities
may be in global form.

                  Except in the case of temporary Securities in global form
(which shall be exchanged in accordance with Section 304(b) or as otherwise
provided in or pursuant to a Board Resolution), if temporary Securities of any
series are issued, the Company will cause definitive Securities of that series
to be prepared without unreasonable delay. After the preparation of definitive
Securities of such series, the temporary Securities of such

                                       25
<PAGE>   35
series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (accompanied by any non-matured 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; provided, however, that no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and provided
further that a definitive Bearer Security shall be delivered in exchange for a
temporary Bearer Security only in compliance with the conditions set forth in
Section 303. 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.

                  (b)      Unless otherwise provided in or pursuant to a Board
Resolution, this Section 304(b) shall govern the exchange of temporary
Securities issued in global form. If temporary Securities of any series are
issued in global form, any such temporary global Security shall, unless
otherwise provided therein, be delivered to the London office of a depositary or
common depositary (the "Common Depositary"), for the benefit of Euroclear and
Clearstream, for credit to the respective accounts of the beneficial owners of
such Securities (or to such other accounts as they may direct).

                  Without unnecessary delay but in any event not later than the
date specified in, or determined pursuant to the terms of, any such temporary
global Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company. On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary global Security and upon receipt of the Company
Order described in Section 303, an equal aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such temporary global Security to be exchanged. The
definitive Securities to be delivered in exchange for any such temporary global
Security shall be in bearer form, registered form, permanent global bearer form
or permanent global registered form, or any combination thereof, as specified as
contemplated by Section 301, and, if any combination thereof is so specified, as
requested by the beneficial owner thereof; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation by
the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by Euroclear
as to the portion of such temporary global Security held for its account then to
be exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by Clearstream as to the portion of such temporary global Security held
for its account then to be exchanged, each in the form set forth in Exhibit A-2
to this Indenture or in such other form as may be established pursuant to
Section 301; and provided further that

                                       26
<PAGE>   36
definitive Bearer Securities shall be delivered in exchange for a portion of a
temporary global Security only in compliance with the requirements of Section
303.

                  Unless otherwise specified in such temporary global Security,
the interest of a beneficial owner of Securities of a series in a temporary
global Security shall be exchanged for definitive Securities of the same series
and of like tenor following the Exchange Date when the account holder instructs
Euroclear or Clearstream, as the case may be, to request such exchange on his
behalf and delivers to Euroclear or Clearstream, as the case may be, a
certificate in the form set forth in Exhibit A-1 to this Indenture (or in such
other form as may be established pursuant to Section 301), dated no earlier than
15 days prior to the Exchange Date, copies of which certificate shall be
available from the offices of Euroclear and Clearstream, the Trustee, any
Authenticating Agent appointed for such series of Securities and each Paying
Agent. Unless otherwise specified in such temporary global Security, any such
exchange shall be made free of charge to the beneficial owners of such temporary
global Security, except that a Person receiving definitive Securities must bear
the cost of insurance, postage, transportation and the like unless such Person
takes delivery of such definitive Securities in person at the offices of
Euroclear or Clearstream. Definitive Securities in bearer form to be delivered
in exchange for any portion of a temporary global Security shall be delivered
only outside the United States.

                  Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and
Clearstream on such Interest Payment Date upon delivery by Euroclear and
Clearstream to the Trustee of a certificate or certificates in the form set
forth in Exhibit A-2 to this Indenture (or in such other forms as may be
established pursuant to Section 301), for credit without further interest on or
after such Interest Payment Date to the respective accounts of Persons who are
the beneficial owners of such temporary global Security on such Interest Payment
Date and who have each delivered to Euroclear or Clearstream, as the case may
be, a certificate dated no earlier than 15 days prior to the Interest Payment
Date occurring prior to such Exchange Date in the form set forth as Exhibit A-1
to this Indenture (or in such other forms as may be established pursuant to
Section 301). Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section 304(b) and of the
third paragraph of Section 303 of this Indenture and the interests of the
Persons who are the beneficial owners of the temporary global Security with
respect to which such certification was made will be exchanged for definitive
Securities of the same series and of like tenor on the Exchange Date or the date
of certification if such date occurs after the Exchange Date, without further
act or deed by such beneficial owners. Except as otherwise provided in this
paragraph, no payments of principal (or premium, if any) or interest, if any,
owing with respect to a beneficial interest in a temporary global Security will
be made unless and until such interest in such temporary global Security shall
have been

                                       27
<PAGE>   37
exchanged for an interest in a definitive Security. Any interest so received by
Euroclear and Clearstream and not paid as herein provided shall be returned to
the Trustee prior to the expiration of two years after such Interest Payment
Date in order to be repaid to the Company.

                  SECTION 305 Registration, Registration of Transfer and
Exchange.

                  The Company shall cause to be kept at the Corporate Trust
Office of the Trustee or in any office or agency of the Company in a Place of
Payment 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 "Security Register") in
which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Registered Securities and of transfers of
Registered Securities. The Security Register shall be in written form or any
other form capable of being converted into written form within a reasonable
time. The Trustee, at its Corporate Trust Office, is hereby initially appointed
"Security Registrar" for the purpose of registering Registered Securities and
transfers of Registered Securities on such Security Register as herein provided.
In the event that the Trustee shall cease to be Security Registrar, it shall
have the right to examine the Security Register at all reasonable times.

                  Upon surrender for registration of transfer of any Registered
Security of any series at any office or agency of the Company in a Place of
Payment for that series, the Company shall execute, and the Trustee shall
authenticate and deliver, subject to the terms and conditions of this Article 3,
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, bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

                  At the option of the Holder, Registered Securities of any
series may be exchanged for other Registered Securities of the same series, of
any authorized denomination or denominations and of a like aggregate principal
amount, containing identical terms and provisions, upon surrender of the
Registered Securities to be exchanged at any 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 with respect to any series of Securities as contemplated by
Section 301, Bearer Securities may not be issued in exchange for Registered
Securities. If (but only if) permitted by the applicable Board Resolution and
(subject to Section 303) set forth in the applicable Officers' Certificate, or
in any indenture supplemental hereto, delivered as contemplated by Section 301,
at the option of the Holder, Bearer Securities of any series may be exchanged
for Registered Securities of the same series of any authorized denominations and
of a like aggregate principal amount and tenor, 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, any such permitted

                                       28
<PAGE>   38
exchange may be effected if the Bearer Securities are accompanied by payment in
funds acceptable to the Company 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 is 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 1002,
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 a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor 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 proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, 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.

                  Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.
Notwithstanding the foregoing, except as otherwise specified as contemplated by
Section 301, any permanent global Security shall be exchangeable only as
provided in this paragraph. If any beneficial owner of an interest in a
permanent global Security is entitled to exchange such interest for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified as contemplated by Section 301 and provided that
any applicable notice provided in the permanent global Security shall have been
given, then without unnecessary delay but in any event not later than the
earliest date on which such interest may be so exchanged, the Company shall
deliver to the Trustee definitive Securities in aggregate principal amount equal
to the principal amount of such beneficial owner's interest in such permanent
global Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such permanent global Security shall be
surrendered by the Common Depositary or such other depositary as shall be
specified in the Company Order with respect thereto to the Trustee, as the
Company's agent for such purpose, to be exchanged, in whole or from time to time
in part, for definitive Securities without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such permanent global
Security, an equal aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of such
permanent global Security to be exchanged which, unless the Securities of the
series are not issuable both as Bearer Securities and as Registered Securities,
as specified as contemplated by Section 301, shall

                                       29
<PAGE>   39
be in the form of Bearer Securities or Registered Securities, or any combination
thereof, as shall be specified by the beneficial owner thereof; provided,
however, that no such exchanges may occur during a period beginning at the
opening of business 15 days before any selection of Securities to be redeemed
and ending on the relevant Redemption Date if the Security for which exchange is
requested may be among those selected for redemption; and provided further that
no Bearer Security delivered in exchange for a portion of a permanent global
Security shall be mailed or otherwise delivered to any location in the United
States. If a Registered Security is issued in exchange for any portion of a
permanent global Security after the close of business at the office or agency
where such exchange occurs 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 proposed date for payment of Defaulted Interest,
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 such Registered Security, but will be payable on such Interest
Payment Date or proposed date for payment, as the case may be, only to the
Person to whom interest in respect of such portion of such permanent global
Security is payable in accordance with the provisions of this Indenture.

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

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

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any
transfer.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange any Security if such Security may be among those
selected for redemption during a period beginning at the opening of business 15
days before selection of the Securities to be redeemed under Section 1103 and
ending at the close of business on (A) if such Securities are issuable only as
Registered Securities, the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the first publication of the relevant notice of redemption or, if such
Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed,

                                       30
<PAGE>   40
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, or (iv) to issue, register the transfer of or
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

                  Each Holder of a Security agrees to indemnify the Company and
the Trustee against any liability that may result from the transfer, exchange or
assignment of such Holder's Security in violation of any provision of this
Indenture and/or applicable United States Federal or state securities law.

                  The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any
interest in any Security (including any transfers between or among Depository
Participants or beneficial owners of interests in any Global Security) other
than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly
required by, the terms of this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

                  SECTION 306 Mutilated, Destroyed, Lost and Stolen Securities.

                  If any mutilated Security or a Security with a mutilated
coupon appertaining to it is surrendered to the Trustee or the Company, together
with, in proper cases, such security or indemnity as may be required by the
Company or the Trustee to save each of them or any agent of either of them
harmless, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new 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 surrendered Security.

                  If there shall be delivered to the Company and to the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any
Security or 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 upon its
request and according to its directions 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 new 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 such destroyed, lost or stolen Security
or to the Security to which such destroyed, lost or stolen coupon appertains.

                                       31
<PAGE>   41
                  Notwithstanding the provisions of the previous two paragraphs,
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, with coupons corresponding to the coupons, if
any, appertaining to such mutilated, destroyed, lost or stolen Security or to
the Security to which such mutilated, destroyed, lost or stolen coupon
appertains, pay such Security or coupon; provided, however, that payment of
principal of (and premium, if any) and interest, if any, on Bearer Securities
shall, except as otherwise provided in Section 1002, be payable only at an
office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 301, 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) connected therewith.

                  Every new Security of any series, together 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 coupons, 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 307 Payment of Interest; Interest Rights Preserved;
Optional Interest Reset.

                  (a)      Except as otherwise specified with respect to a
series of Securities in accordance with the provisions of Section 301, interest,
if any, on any Registered Security that 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 of the Company maintained for such purpose pursuant to Section
1002; provided, however, that each installment of interest, if any, on any
Registered Security may at the Company's option be paid by (i) mailing a check
for such interest, payable to or upon the written order of the Person entitled
thereto pursuant to Section 309, to the address of such Person as it appears on
the Security Register or (ii) transfer to an account maintained by the payee
inside the United States.

                  Unless otherwise provided as contemplated by Section 301 with
respect to the Securities of any series, payment of interest, if any, may be
made, in the case of a

                                       32
<PAGE>   42
Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

                  Unless otherwise provided as contemplated by Section 301,
every permanent global Security will provide that interest, if any, payable on
any Interest Payment Date will be paid to each of Euroclear and Clearstream with
respect to that portion of such permanent global Security held for its account
by the Common Depositary, for the purpose of permitting each of Euroclear and
Clearstream to credit the interest, if any, received by it in respect of such
permanent global Security to the accounts of the beneficial owners thereof.

                  In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business
(at an office or agency in a Place of Payment for such series) on any Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date 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.

                  Except as otherwise specified with respect to a series of
Securities in accordance with the provisions of Section 301, any interest on any
Registered Security of any series that 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 registered Holder thereof
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

                  (1)      The Company may elect to make payment of any
         Defaulted Interest to the Persons in whose names the 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 notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Registered
         Security of such series and the date of the proposed payment (which
         shall not be less than 20 days after such notice is received by the
         Trustee), and at the same time the Company shall deposit with the
         Trustee an amount of money in the Currency in which the Securities of
         such series are payable (except as otherwise specified pursuant to
         Section 301 for the Securities of such series and except, if
         applicable, as provided in Sections 312(b), 312(d) and 312(e)) 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 on or prior to the date of the proposed payment, such
         money when deposited to be held in trust for the benefit of the Persons
         entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than

                                       33
<PAGE>   43
         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 Registered Securities of such series at his address
         as it appears in the Security Register not less than 10 days prior to
         such Special Record Date.

                  Notice of the proposed payment of such Defaulted Interest and
         the Special Record Date therefor having been mailed as aforesaid, such
         Defaulted Interest shall be paid to the Persons in whose names the
         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). In case a Bearer Security of any series is surrendered at
         the office or agency in a Place of Payment for such series in exchange
         for a Registered Security of such series after the close of business at
         such office or agency on any Special Record Date and before the opening
         of business at such office or agency on the related proposed date for
         payment of Defaulted Interest, such Bearer Security shall be
         surrendered without the coupon relating to such proposed date of
         payment and Defaulted Interest will not be payable on such proposed
         date of payment 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.

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

                  (b)      The provisions of this Section 307(b) may be made
applicable to any series of Securities pursuant to Section 301 (with such
modifications, additions or substitutions as may be specified pursuant to such
Section 301). The interest rate (or the spread or spread multiplier used to
calculate such interest rate, if applicable) on any Security of such series may
be reset by the Company on the date or dates specified on the face of such
Security (each an "Optional Reset Date"). The Company may exercise such option
with respect to such Security by notifying the Trustee of such exercise at least
45 but not more than 60 days prior to an Optional Reset Date for such Security.
Not later than 40 days prior to each Optional Reset Date, the Trustee shall
transmit, in the manner provided for in Section 106, to the Holder of any such
Security a notice (the "Reset Notice") indicating whether the Company has
elected to reset the interest rate (or the spread or spread multiplier used to
calculate such interest rate, if applicable), and if so (i) such new interest
rate (or such new spread or spread multiplier, if applicable) and (ii) the
provisions, if any, for redemption during the period from such Optional Reset
Date to the next Optional Reset Date or if there is no such next Optional Reset
Date, to

                                       34
<PAGE>   44
the Stated Maturity of such Security (each such period a "Subsequent Interest
Period"), including the date or dates on which or the period or periods during
which and the price or prices at which such redemption may occur during the
Subsequent Interest Period.

                  Notwithstanding the foregoing, not later than 20 days prior to
the Optional Reset Date, the Company may, at its option, revoke the interest
rate (or the spread or spread multiplier used to calculate such interest rate,
if applicable) provided for in the Reset Notice and establish a higher interest
rate (or a spread or spread multiplier providing for a higher interest rate, if
applicable), for the Subsequent Interest Period by causing the Trustee to
transmit, in the manner provided for in Section 106, notice of such higher
interest rate (or such spread or spread multiplier providing for a higher
interest rate, if applicable) to the Holder of such Security. Such notice shall
be irrevocable. All Securities with respect to which the interest rate (or the
spread or spread multiplier used to calculate such interest rate, if applicable)
is reset on an Optional Reset Date, and with respect to which the Holders of
such Securities have not tendered such Securities for repayment (or have validly
revoked any such tender) pursuant to the next succeeding paragraph, will bear
such higher interest rate (or such spread or spread multiplier providing for a
higher interest rate, if applicable).

                  The Holder of any such Security may have the option to elect
repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest
accrued to such Optional Reset Date. In order to obtain repayment on an Optional
Reset Date, the Holder must follow the procedures set forth in Article Thirteen
for repayment at the option of Holders except that the period for delivery or
notification to the Trustee shall be at least 25 but not more than 35 days prior
to such Optional Reset Date and except that, if the Holder has tendered any
Security for repayment pursuant to the Reset Notice, the Holder may, by written
notice to the Trustee, revoke such tender or repayment until the close of
business on the tenth day before such Optional Reset Date.

                  Subject to the foregoing provisions of this Section and
Section 305, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

                  SECTION 308 Optional Extension of Maturity.

                  The provisions of this Section 308 may be made applicable to
any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 301).
The Stated Maturity of any Security of such series may be extended at the option
of the Company for the period or periods specified on the face of such Security
(each an "Extension Period") up to but not beyond the date (the "Final
Maturity") set forth on the face of such Security. The Company may exercise such
option with respect to any Security by notifying the Trustee of such exercise at
least 45 but not more than 60 days prior to the Stated Maturity of such Security
in effect prior to the exercise of such option (the "Original Stated Maturity").
If the Company exercises such option, the Trustee shall transmit, in the manner
provided

                                       35
<PAGE>   45
for in Section 106, to the Holder of such Security not later than 40 days prior
to the Original Stated Maturity a notice (the "Extension Notice") indicating (i)
the election of the Company to extend the Stated Maturity, (ii) the new Stated
Maturity, (iii) the interest rate (or spread, spread multiplier or other formula
used to calculate such interest rate, if applicable), if any, applicable to the
Extension Period and (iv) the provisions, if any, for redemption during such
Extension Period. Upon the Trustee's transmittal of the Extension Notice, the
Stated Maturity of such Security shall be extended automatically and, except as
modified by the Extension Notice and as described in the next paragraph, such
Security will have the same terms as prior to the transmittal of such Extension
Notice.

                  Notwithstanding the foregoing, not later than 20 days before
the Original Stated Maturity of such Security, the Company may, at its option,
revoke the interest rate (or spread, spread multiplier or other formula used to
calculate such interest rate, if applicable) provided for in the Extension
Notice and establish a higher interest rate (or spread, spread multiplier or
other formula used to calculate such higher interest rate, if applicable) for
the Extension Period by causing the Trustee to transmit, in the manner provided
for in Section 106, notice of such higher interest rate (or spread, spread
multiplier or other formula used to calculate such interest rate, if applicable)
to the Holder of such Security. Such notice shall be irrevocable. All Securities
with respect to which the Stated Maturity is extended will bear such higher
interest rate.

                  If the Company extends the Stated Maturity of any Security,
the Holder will have the option to elect repayment of such Security by the
Company on the Original Stated Maturity at a price equal to the principal amount
thereof, plus interest accrued to such date. In order to obtain repayment on the
Original Stated Maturity once the Company has extended the Stated Maturity
thereof, the Holder must follow the procedures set forth in Article Thirteen for
repayment at the option of Holders, except that the period for delivery or
notification to the Trustee shall be at least 25 but not more than 35 days prior
to the Original Stated Maturity and except that, if the Holder has tendered any
Security for repayment pursuant to an Extension Notice, the Holder may by
written notice to the Trustee revoke such tender for repayment until the close
of business on the tenth day before the Original Stated Maturity.

                  SECTION 309 Persons Deemed Owners.

                  Prior to due presentment of a 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 Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307)
interest, if any, on such Registered Security and for all other purposes
whatsoever, whether or not such Registered Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

                  Title to any Bearer Security and any coupons appertaining
thereto shall pass by delivery. The Company, the Trustee and any agent of the
Company or the

                                       36
<PAGE>   46
Trustee may treat the bearer of any Bearer Security and the
bearer of any coupon as the absolute owner of such Security or coupon for the
purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not such Security or coupon 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.

                  None of the Company, the Trustee, any Paying Agent or the
Security Registrar will 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 global
Security, nothing herein shall prevent the Company, the Trustee, or any agent of
the Company or the Trustee, from giving effect to any written certification,
proxy or other authorization furnished by any depositary, as a Holder, with
respect to such global Security or impair, as between such depositary and owners
of beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such global Security.

                  SECTION 310 Cancellation.

                  All Securities and coupons surrendered for payment,
redemption, repayment at the option of the Holder, registration of transfer or
exchange or for credit against any sinking fund payment shall, if surrendered to
any Person other than the Trustee, be delivered to the Trustee, and any such
Securities and coupons and Securities and coupons surrendered directly to the
Trustee for any such purpose shall be promptly cancelled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. If the
Company shall so acquire any of the Securities, however, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are surrendered to the Trustee for
cancellation. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. Cancelled Securities and coupons held by the
Trustee shall be destroyed by the Trustee and the Trustee shall deliver a
certificate of such destruction to the Company, unless by a Company Order the
Company directs their return to it.

                  SECTION 311 Computation of Interest.

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

                  SECTION 312 Currency and Manner of Payments in Respect of
Securities.

                  (a)      Unless otherwise specified with respect to any
Securities pursuant to Section 301, with respect to Registered Securities of any
series not permitting the election provided for in paragraph (b) below or the
Holders of which have not made the election provided for in paragraph (b) below,
and with respect to Bearer Securities of any series, except as provided in
paragraph (d) below, payment of the principal of (and premium, if any) and
interest, if any, on any Registered or Bearer Security of such series will be
made in the Currency in which such Registered Security or Bearer Security, as
the case may be, is payable. The provisions of this Section 312 may be modified
or superseded with respect to any Securities pursuant to Section 301.

                  (b)      It may be provided pursuant to Section 301 with
respect to Registered Securities of any series that Holders shall have the
option, subject to paragraphs (d) and (e) below, to receive payments of
principal of (or premium, if any) or interest, if any, on such Registered
Securities in any of the Currencies which may be designated for such election by
delivering to the Trustee for such series of Registered Securities a written
election with signature guarantees and in the applicable form established
pursuant to Section 301, not later than the close of business on the Election
Date immediately preceding the applicable payment date. If a Holder so elects to
receive such payments in any such Currency, 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 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
Four or Fourteen or with respect to which a notice of redemption has been given
by the Company or a notice of option to elect repayment has been sent by such
Holder or such transferee). Any Holder of any such Registered Security who shall
not have delivered any such election to the Trustee of such series of Registered
Securities 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 as provided in Section 312(a). The Trustee for each such series of
Registered Securities shall notify 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)      Unless otherwise specified pursuant to Section 301,
if the election referred to in paragraph (b) above has been provided for
pursuant to Section 301, then, unless otherwise specified pursuant to Section
301, not later than the fourth Business Day after the Election Date for each
payment date for Registered Securities of any series, the Exchange Rate Agent
will deliver to the Company a written notice specifying the Currency in which
Registered Securities of such series are payable, the respective aggregate
amounts of principal of (and premium, if any) and interest, if any, on the

                                       38
<PAGE>   48
Registered Securities to be paid on such payment date, specifying the amounts in
such Currency so payable in respect of the Registered Securities as to which the
Holders of Registered Securities denominated in any Currency shall have elected
to be paid in another Currency as provided in paragraph (b) above. If the
election referred to in paragraph (b) above has been provided for pursuant to
Section 301 and if at least one Holder has made such election, then, unless
otherwise specified pursuant to Section 301, on the second Business Day
preceding such payment date the Company will deliver to the Trustee for such
series of Registered Securities an Exchange Rate Officer's Certificate in
respect of the Dollar or Foreign Currency or Currencies payments to be made on
such payment date. Unless otherwise specified pursuant to Section 301, the
Dollar or Foreign Currency or Currencies amount receivable by Holders of
Registered Securities who have elected payment in a Currency 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 in which any of the Securities are denominated or payable other
than pursuant to an election provided for pursuant to paragraph (b) above, then
with respect to each date for the payment of principal of (and premium, if any)
and interest, if any, on the applicable Securities denominated or payable in
such Foreign Currency occurring after the last date on which such Foreign
Currency was used (the "Conversion Date"), the Dollar shall be the currency of
payment for use on each such payment date. Unless otherwise specified pursuant
to Section 301, the Dollar amount to be paid by the Company to the Trustee of
each such series of Securities and by such Trustee or any 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 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 301,
if the Holder of a Registered Security denominated in any Currency shall have
elected to be paid in another Currency as provided in paragraph (b) above, and a
Conversion Event occurs with respect to such elected Currency, such Holder shall
receive payment in the Currency in which payment would have been made in the
absence of such election; and if a Conversion Event occurs with respect to the
Currency 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 312.

                  (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 converting the specified Foreign Currency into
Dollars at the Market Exchange Rate on the Conversion Date.

                                       39
<PAGE>   49
                  (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 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 312, the following terms
shall have the following meanings:

                  A "Component Currency" shall mean any currency which, on the
         Conversion Date, was a component currency of the relevant currency
         unit, including, but not limited to, the euro.

                  A "Specified Amount" of a Component Currency shall mean the
         number of units of such Component Currency or fractions thereof which
         were represented in the relevant currency unit, including, but not
         limited to, the euro, 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 amounts of such two or more currencies, having an
         aggregate Dollar Equivalent value at the Market Exchange Rate on the
         date of such replacement equal to the Dollar Equivalent of the
         Specified Amount of such former Component Currency at the Market
         Exchange Rate immediately before such division, 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, including, but not limited to, the euro, 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.

                  "Election Date" shall mean the Regular Record Date for the
         applicable series of Registered Securities or at least 16 days prior to
         Maturity, as the case may be, or such other prior date for any series
         of Registered Securities as specified pursuant to clause 13 of Section
         301 by which the written election referred to in Section 312(b) may be
         made.

<PAGE>   50
                  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 for the appropriate series of Securities
and all Holders of such Securities denominated or payable in the relevant
Currency. The Exchange Rate Agent shall promptly give written notice to the
Company and the Trustee for the appropriate series of Securities 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 immediately give written notice thereof to the Trustee of the appropriate
series of Securities and to the Exchange Rate Agent (and such Trustee will
promptly thereafter give notice in the manner provided in Section 106 to the
affected Holders) specifying the Conversion Date. In the event the Company so
determines that a Conversion Event has occurred with respect to the euro or any
other currency unit in which Securities are denominated or payable, the Company
will immediately give written notice thereof to the Trustee of the appropriate
series of Securities and to the Exchange Rate Agent (and such Trustee will
promptly thereafter give notice in the manner provided in Section 106 to the
affected Holders) specifying the Conversion Date and the Specified Amount of
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 of the appropriate series of
Securities and to the Exchange Rate Agent.

                  The Trustee of the appropriate series of Securities shall be
fully justified and protected in conclusively 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 313 Appointment and Resignation of Successor Exchange
Rate Agent.

                  (a)      Unless otherwise specified pursuant to Section 301,
if and so long as the Securities of any series (i) are denominated in a Foreign
Currency or (ii) may be payable in a Foreign Currency, 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 301 for the purpose of determining the applicable
rate of exchange and, if applicable, for the purpose of converting the issued
Foreign Currency into the applicable payment Currency for the payment of
principal (and premium, if any) and interest, if any, pursuant to Section 312.

                                       41
<PAGE>   51
                  (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, by or pursuant to a Board Resolution, 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 301, 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).

                  SECTION 314 CUSIP Numbers.

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

                           SATISFACTION AND DISCHARGE

                  SECTION 401 Satisfaction and Discharge of Indenture.

                  Unless otherwise specified pursuant to Section 301, this
Indenture shall upon Company Request cease to be of further effect with respect
to any series of Securities specified in such Company Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series expressly provided for herein or pursuant hereto and any right to receive
Additional Amounts, as provided in Section 1005), and the Trustee, upon receipt
of a Company Order, and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series when

                  (1)      either

                           (A)      all Securities of such series theretofore
                  authenticated and delivered and all coupons, if any,
                  appertaining thereto (other than

                  exchange for Registered Securities and maturing after such
                  exchange, whose surrender is not required or has been waived
                  as provided in Section 305, (ii) Securities and coupons of
                  such series which have been destroyed, lost or stolen and
                  which have been replaced or paid as provided in Section 306,
                  (iii) coupons appertaining to Securities called for redemption
                  and maturing after the relevant Redemption Date, whose
                  surrender has been waived as provided in Section 1106, and
                  (iv) Securities and coupons of such series for whose payment
                  money has theretofore been deposited in trust or segregated
                  and held in trust by the Company and thereafter repaid to the
                  Company or discharged from such trust, as provided in Section
                  1003) have been delivered to the Trustee for cancellation; or

                           (B)      all Securities of such series and, in the
                  case of (i) or (ii) below, any coupons appertaining thereto
                  not theretofore delivered to the Trustee for cancellation

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

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

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

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

                  (3)      the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture as to such series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the

Section 1301 and with respect to any rights of Holders to convert or exchange
such Securities into other Securities, shall survive. These obligations shall
continue to be governed and construed in accordance with Section 111.

                  SECTION 402 Application of Trust Funds.

                  Subject to the provisions of the last paragraph of Section
1003, all money deposited with the Trustee pursuant to Section 401 shall be held
in trust and applied by it, in accordance with the provisions of the Securities,
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 thereto, of the principal (and
premium, if any) and interest, if any, for whose payment 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.

                                    REMEDIES

                  SECTION 501 Events of Default.

                  "Event of Default", wherever used herein with respect to any
particular series of Securities, means any one of the following events as such
events may be otherwise amended in accordance with Section 301 (whatever the
reason for such Event of Default and whether or not it shall be occasioned by
the provisions of Article Sixteen or be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

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

                  (2)      default in the payment of the principal of (or
         premium, if any, on) any Security of that series when it becomes due

         when and as due by the terms of any Security of that series; or

                  (4)      default in the performance, or breach, of any
         covenant or agreement of the Company in this Indenture with respect to

         whose breach is elsewhere in this Section specifically dealt with), and
         continuance of such default or breach for a period of 60 days after
         there has been given, by registered or certified mail, to the 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; or

                  (5)      the Company pursuant to or within the meaning of any
         Bankruptcy Law:

                           (A)      commences a voluntary case or proceedings,

                           (B)      consents to the entry of an order for relief

                  of it or for all or substantially all of its property,

                           (D)      makes a general assignment for the benefit
                  of its creditors, or

                           (E)      issues a public announcement admitting its
                  inability to pay its debts generally as they become due;

         or

                  (6)      a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (A)      is for relief against the Company in an

                           (B)      appoints a Custodian of the Company or for

                  SECTION 502 Acceleration of Maturity; Rescission and
Annulment.

                                       45
<PAGE>   55
                  If an Event of Default (other than an Event of Default
specified in section 501(5) or 501(6) with respect to the Company) with respect
to Securities of any series at the time Outstanding occurs and is continuing,
then and in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of that series may declare the
principal (or, if any Securities are Original Issue Discount Securities or
Indexed Securities, such portion of the principal as may be specified in the
terms thereof) and accrued interest of all the Securities of that series to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the Holders), and upon any such declaration such principal
or specified portion thereof and interest shall become immediately due and
payable. If an Event of Default specified in Section 501(5) or 501(6) with
respect to the Company occurs, the amounts described above with respect to the
Outstanding Securities of all series shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holder. Upon payment of such principal and interest, all of the Company's
obligations under the Securities of such Series and this Indenture, other than
obligations under Section 606, shall terminate.

                  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 provided in this Article, the Holders of a majority in principal
amount of the Outstanding Securities of that series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:

                  (1)      the Company has paid or deposited with the Trustee a
         sum sufficient in cash to pay all principal, interest and Additional
         Amounts which have become due other than by such declaration of
         acceleration, interest or any such overdue amounts, and amounts owing
         the Trustee;

                  (2)      all Events of Default with respect to Securities of
         that series, other than the nonpayment of the principal of (or premium,
         if any) or interest on Securities of that series which have become due
         solely by such declaration of acceleration, have been cured or waived
         as provided in Section 513; and

                  (3)      such rescission would not conflict with any judgment
         or decree of a court of competent jurisdiction.

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

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

                  The Company covenants that if:

                  (1)      default is made in the payment of any installment of
         interest or Additional Amounts on any Security of any series and any
         related coupon when

                                       46
<PAGE>   56
         such interest or Additional Amounts 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 its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium, if any) and interest, if any, with interest upon any overdue principal
(and premium, if any) and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest, if any, at the
rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

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

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

                  SECTION 504 Trustee May File Proofs of Claim.

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

                  (a)      to file and prove a claim for the whole amount of
         principal (or in the case of Original Issue Discount Securities or
         Indexed Securities, such portion of the principal as may be provided
         for in the terms thereof) (and premium, if any)

                                       47
<PAGE>   57
         and interest, if any, owing and unpaid in respect of the Securities and
         to file such other papers or documents as may be necessary or advisable
         in order to have the claims of the Trustee (including any claim for the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel) and of the Holders allowed in such
         judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series and coupons to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

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

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

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

                  SECTION 506 Application of Money Collected.

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

                  FIRST: To the payment of all amounts due the Trustee and any
         predecessor Trustee under Section 606;

                                       48
<PAGE>   58
                  SECOND: Subject to Article 16, to the payment of the amounts
         then due and unpaid upon the Securities and coupons for principal (and
         premium, if any) and interest, if any, in respect of which or for the
         benefit of which such money has been collected, ratably, without
         preference or priority of any kind, according to the aggregate amounts
         due and payable on such Securities and coupons for principal (and
         premium, if any) and interest, if any, respectively; and

                  THIRD: To the payment of the remainder, if any, to the
         Company.

                  SECTION 507 Limitation on Suits.

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

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

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

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

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

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

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

                  SECTION 508 Unconditional Right of Holders to Receive
Principal, Premium and Interest and Additional Amounts, if Any.

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security or coupon shall have the right which is absolute and
unconditional to receive payment of the principal of (and premium, if any) and
(subject to Sections 305 and 307) interest, if any, and Additional Amounts, if
any, on such Security or payment of such

                                       49
<PAGE>   59
coupon on the respective due dates expressed in such Security or coupon (or, in
the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

                  SECTION 509 Restoration of Rights and Remedies.

                  If the Trustee or any Holder of a Security or coupon 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 the Company, the Trustee and the Holders of Securities and coupons
shall, subject to any determination in such proceeding, be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

                  SECTION 510 Rights and Remedies Cumulative.

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

                  SECTION 511 Delay or Omission Not Waiver.

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

                  SECTION 512 Control by Holders of Securities.

                  The Holders of a majority in principal amount of the
Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee with respect
to the Securities of such series, provided that

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

                                       50
<PAGE>   60
                  (2)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such direction, and

                  (3)      the Trustee need not take any action which might
         involve it in personal liability or be unjustly prejudicial to the
         Holders of Securities of such series not consenting.

                  SECTION 513 Undertaking for Costs.

                  All parties to this Indenture agree that in any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as a Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorney's fees and expenses,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant, provided that this
Section 513 shall not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 508 hereof, or a suit by Holders of more than 10% in
principal amount of the then Outstanding Securities.

                  SECTION 514 Waiver of Past Defaults.

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

                  (1)      in the payment of the principal of (or premium, if
         any) or interest, if any, or Additional Amounts on any Security of such
         series or any related coupons, or

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

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

                  SECTION 515 Waiver of Usury, Stay or Extension Laws.

                  The Company covenants (to the extent that it may lawfully do
so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law
or any usury or other law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it

                                       51
<PAGE>   61
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                                  ARTICLE SIX

                                   THE TRUSTEE

                  SECTION 601 Notice of Defaults.

                  Within five days after the earlier of receipt from the Company
of notice of the occurrence of a Default or Event of Default hereunder or the
date such occurrence hereunder actually becomes known to a Responsible Officer
of the Trustee, the Trustee shall transmit to all Holders of Securities of such
series, in the manner and to the extent provided in TIA Section 313(c), notice
of such Default hereunder known to the Trustee, unless such Default shall have
been cured or waived; provided, however, that, except in the case of a Default
in the payment of the principal of (or premium, if any) or interest, if any, on
any Security of such series, or in the payment of any sinking or purchase fund
installment with respect to the Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interests of the Holders of the Securities and coupons of such
series; and provided further that in the case of any Default or breach of the
character specified in Section 501(4) with respect to the Securities and coupons
of such series, no such notice to Holders shall be given until at least 60 days
after the occurrence thereof unless otherwise specified in accordance with
Section 301.

                  SECTION 602 Certain Rights of Trustee.

                  Subject to the provisions of TIA Section 315(a) through
315(d):

                  (1)      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.

                  (2)      The Trustee may conclusively rely and shall be
         protected in acting or refraining from acting upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, coupon or other paper
         or document believed by it to be genuine and to have been signed or
         presented by the proper party or parties.

                  (3)      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.

                  (4)      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

                                       52
<PAGE>   62
         Holders of a majority in principal amount of the Outstanding Securities
         of any series, determined as provided in Sections 101 and 104.

                  (5)      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 303 which shall be sufficiently evidenced as
         provided therein) and any resolution of the Board of Directors may be
         sufficiently evidenced by a Board Resolution.

                  (6)      Whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon a Board Resolution,
         an Opinion of Counsel or an Officers' Certificate.

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

                  (8)      The Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Indenture at the
         request or direction of any of the Holders of Securities of any series
         or any related coupons pursuant to this Indenture, unless such Holders
         shall have offered to the Trustee security or indemnity reasonably
         satisfactory to the Trustee against the costs, expenses and liabilities
         which might be incurred by it in compliance with such request or
         direction.

                  (9)      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, coupon 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 but in the
         case of any certificate or opinion specifically required by the
         Indenture to be delivered to the Trustee, the Trustee shall have a duty
         to examine the same to determine whether they conform to the Indenture
         requirements.

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

                                       53
<PAGE>   63
                  (11)     The Trustee shall not be liable for any action taken,
         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture other than any liabilities arising out of the
         negligence of the Trustee.

                  (12)     The rights, privileges, protections, immunities and
         benefits given to the Trustee, including, without limitation, its right
         to be indemnified, are extended to, and shall be enforceable by, the
         Trustee in each of its capacities hereunder, and to each agent,
         custodian and other Person employed to act hereunder.

                  (13)     The Trustee may request that the Company deliver an
         Officers' Certificate setting forth the names of individuals and/or
         titles of officers authorized at such time to take specified actions
         pursuant to this Indenture, which Officers' Certificate may be signed
         by any person authorized to sign an Officers' Certificate, including
         any person specified as so authorized in any such certificate
         previously delivered and not superseded.

                  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 any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

                  SECTION 603 Not Responsible for Recitals or Issuance of
Securities.

                  The recitals contained herein and in the Securities, except
the Trustee's certificate of authentication, and in any coupons shall be taken
as the statements of the Company, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate, subject to the qualifications set forth therein. Neither the Trustee
nor any Authenticating Agent shall be accountable for the use or application by
the Company of Securities or the proceeds thereof.

                  SECTION 604 May Hold Securities.

                  The Trustee, any Paying Agent, Security Registrar,
Authenticating Agent 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 TIA Sections 310(b) and 311, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, Paying Agent, Security
Registrar, Authenticating Agent or such other agent.

                  SECTION 605 Money Held in Trust.

                                       54
<PAGE>   64
                  Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed with the Company.

                  SECTION 606 Compensation and Reimbursement.

                  The Company agrees:

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

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

                  (3)      to indemnify each of the Trustee and any predecessor
         Trustee for, and to hold it harmless against, any loss, damage, claims,
         liability or expense incurred without negligence or bad faith on its
         own part, arising out of or in connection with the acceptance or
         administration of the trust or trusts hereunder, including the costs
         and expenses of defending itself against any claim (whether asserted by
         the Company or any Holder or any other Person) or liability in
         connection with the exercise or performance of any of its powers or
         duties hereunder.

                  As security for the performance of the obligations of the
Company under this Section, the Trustee shall have a claim prior to the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of (or premium, if any)
or interest, if any, on particular Securities or any coupons.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 501(5) or (6) occurs, the expenses and
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

                  SECTION 607 Corporate Trustee Required; Eligibility.

                  There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. 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

                                       55
<PAGE>   65
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

                  SECTION 608 Resignation and Removal; Appointment of Successor.

                  (a)      No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 609.

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

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

                  (d)      If at any time:

                  (1)      the Trustee shall fail to comply with the provisions
         of TIA Section 310(b) 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

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

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

                  (e)      If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
a notice of resignation or the delivery of an Act of removal, the Trustee
resigning or being removed

                                       56
<PAGE>   66
or any Holder who has been a bona fide Holder of Securities for at least six
months, may petition any court of competent jurisdiction for the appointment of
a successor Trustee.

                  (f)      If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause with respect to the Securities of one or more series, the Company, by
or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or
Trustees with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
be only one Trustee with respect to the Securities of any particular series).
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, 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 of Securities and accepted appointment in the manner hereinafter
provided, any Holder of a Security 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 Securities of such series.

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

                  SECTION 609 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, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on 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, subject nevertheless to its
claim, if any, provided for in Section 606.

                                       57
<PAGE>   67

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

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

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

                  SECTION 610 Merger, Conversion, Consolidation or Succession to
Business.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all 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 parties hereto. In case any Securities or coupons

                                       58
<PAGE>   68

shall have been authenticated, but not delivered, by the Trustee then in office,
any successor by merger, conversion or consolidation to such authenticating
Trustee may adopt such authentication and deliver the Securities or coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities or coupons. In case any Securities or coupons
shall not have been authenticated by such predecessor Trustee, any such
successor Trustee may authenticate and deliver such Securities or coupons, in
either its own name or that of its predecessor Trustee, with the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee.

                  SECTION 611 Appointment of Authenticating Agent.

                  At any time when any of the Securities remain Outstanding, the
Trustee may appoint an Authenticating Agent or Agents with respect to one or
more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon exchange,
registration of transfer or partial redemption thereof, 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
reasonably acceptable to the Company and, except as may otherwise be provided
pursuant to Section 301, 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 $50,000,000 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 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.

                                       59
<PAGE>   69

                  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 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 106. 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 reasonable compensation 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 therein
referred to in the within-mentioned Indenture.

                                    THE BANK OF NEW YORK
                                         as Trustee

                                    By

                                        ________________________
                                        Authorized Signatory

                  SECTION 612 Conflicting Interests.

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

                  The indenture dated as of December 16, 1996, for the Company's
10 3/4% Senior Subordinated Notes due 2006 between the Company and The Bank of
New York shall be deemed to be specifically described herein for the purposes of
clause (i) of the first proviso contained in Section 310(b) of the Trust
Indenture Act.

                  SECTION 613 Appointment of Co-Trustee.

                  (a) For the purpose of meeting any legal requirements of any
jurisdiction in which the Company may at the time be located in connection with
the enforcement of any right or the taking of any action on behalf of the
Holders of any Securities issued hereunder, the Trustee shall have the power and
may execute and deliver all instruments necessary to appoint one or more Persons
to act as a co-trustee or co-trustees, or separate trustee or separate trustees,
such powers, duties, obligations, rights and trusts as the Trustee may consider
necessary or desirable. Each co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a trustee under Section 607. The
Trustee shall promptly notify the Holders and the Company of the appointment of
a co-trustee or separate trustee under this section.

                  (b) Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                  (i) all rights, powers, duties and obligations conferred or
         imposed upon the Trustee shall be conferred or imposed upon and
         exercised or performed by the Trustee and such separate trustee or
         co-trustee jointly (it being understood that such separate trustee or
         co-trustee is not authorized to act separately without the Trustee
         joining in such act), except to the extent that under any law of any
         jurisdiction in which any particular act or acts are to be performed
         the Trustee shall be incompetent or unqualified to perform such act or
         acts, in which event such rights, powers, duties and obligations shall
         be exercised and performed singly by such separate trustee or
         co-trustee, but solely at the direction of the Trustee;

                  (ii) no trustee hereunder shall be personally liable by reason
         of any act or omission of any other trustee hereunder;

         and authority, to the extent not prohibited by law, to do any lawful

                  CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER

                  SECTION 801 Company May Consolidate, Etc., Only on Certain
Terms.

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

                  (1) either the Company shall be the continuing corporation, or
         the corporation (if other than the Company) formed by such
         consolidation or into which the Company is merged or the Person which
         acquires by conveyance or transfer the properties and assets of the
         Company substantially as an entirety shall expressly assume, by an
         indenture supplemental hereto, executed and delivered to the Trustee,
         in form satisfactory to the Trustee, the due and punctual payment of
         the principal of (and premium, if any) and interest, if any, on all the
         Securities and the performance of every covenant of this Indenture on
         the part of the Company to be performed or observed;

                  (2) immediately after giving effect to such transaction, no
         Default or Event of Default shall have occurred and be continuing; and

                  (3) the Company and the successor Person have delivered to the
         Trustee an Officers' Certificate and an Opinion of Counsel each stating
         that such consolidation, merger, conveyance or transfer and such
         supplemental indenture

                                       64
<PAGE>   74

         comply with this Article and that all conditions precedent herein
         provided for relating to such transaction have been complied with.

                  SECTION 802 Successor Person Substituted.

                  Upon any consolidation or merger, or any conveyance or
transfer of the properties and assets of the Company substantially as an
entirety in accordance with Section 801, the successor corporation formed by
such consolidation or into which the Company is merged or the successor Person
to which such conveyance or transfer is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor had been named as the
Company herein; and in the event of any such conveyance or transfer (except by a
lease), the Company shall be discharged from all obligations and covenants under
this Indenture and the Securities and coupons and may be dissolved and
liquidated.

                  Such successor entity thereupon may cause to be signed, and
may issue either in its own name or in the name of the Company, any or all of
the Securities issuable hereunder which theretofore shall not have been signed
by the Company and delivered to the Trustee; and, upon the order of such
successor entity, instead of the Company, and subject to all the terms,
conditions and limitations prescribed in this Indenture, the Trustee shall
authenticate and shall deliver any Securities which previously shall have been
signed and delivered by the officers of the Company to the Trustee for
authentication, and any Securities which such successor entity thereafter shall
cause to be signed and delivered to the Trustee for that purpose. All the
Securities of any series so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Securities of such series
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

                  In case of any such merger in which the Company is not the
surviving corporation or any such consolidation, sale, lease, assignment,
transfer or conveyance, such changes in phraseology and form (but not in
substance) may be made in the Securities thereafter to be issued as may be
appropriate.

                  SECTION 803 Officers' Certificate and Opinion of Counsel.

                  Any consolidation, merger, sale, conveyance, assignment,
transfer or lease permitted under Section 801 is also subject to the condition
that the Trustee shall have received an Officers' Certificate and an Opinion of
Counsel to the effect that any such consolidation, merger, sale, conveyance,
transfer, assignment or lease, and the assumption by any successor Person and
any such supplemental indenture, comply with the provisions of this Article and
that all conditions precedent herein provided for relating to such transaction
have been complied with.

                             SUPPLEMENTAL INDENTURES

                  SECTION 901 Supplemental Indentures Without Consent of
Holders.

                  Without the consent of any Holders of Securities or coupons,
the Company, when authorized by or pursuant to a Board Resolution, and the
Trustee, at any time and from time to time, may enter into one or more
indentures supplemental hereto, in form satisfactory to the Trustee, for any of
the following purposes:

                  (1) to evidence the succession of another Person to the
         Company and the assumption by any such successor of the covenants of
         the Company herein and in the Securities contained; 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 surrender any right or power herein
         conferred upon the Company; or

                  (3) to add any additional Events of Default for the benefit of
         the Holders of all or any series of Securities (and if such Events of
         Default are to be for the benefit of less than all series of
         Securities, stating that such Events of Default are expressly being
         included solely for the benefit of such series); provided, however,
         that in respect of any such additional Events of Default such
         supplemental indenture may provide for a particular period of grace
         after default (which period may be shorter or longer than that allowed
         in the case of other defaults) or may provide for an immediate
         enforcement upon such default or may limit the remedies available to
         the Trustee upon such default or may limit the right of the Holders of
         a majority in aggregate principal amount of that or those series of
         Securities to which such additional Events of Default apply to waive
         such default; or

                  (4) to add to or change any of the provisions of this
         Indenture to provide that Bearer Securities may be registrable as to
         principal, to change or eliminate any restrictions on the payment of
         principal of or any premium or interest on Bearer Securities, to permit
         Bearer Securities to be issued in exchange for Registered Securities,
         to permit Bearer Securities to be issued in exchange for Bearer
         Securities of other authorized denominations or to permit or facilitate
         the issuance of Securities in uncertificated form; provided that any
         such action shall not adversely affect the interests of the Holders of
         Securities of any series or any related coupons in any material
         respect; or

                  (5) to change or eliminate any of the provisions of this
         Indenture; provided that any such change or elimination shall become
         effective only when

                                       66
<PAGE>   76

         there is no Security Outstanding of any series created prior to the
         execution of such supplemental indenture which is entitled to the
         benefit of such provision; or

                  (6) to secure the Securities pursuant to the requirements of
         such indenture supplement, if applicable; or

                  (7) to establish the form or terms of Securities of any series
         and any related coupons as permitted by Sections 201 and 301, including
         the provisions and procedures relating to Securities convertible into
         or exchangeable for any securities of any Person (including the
         Company); or

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

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

                  (10) to supplement any of the provisions of this Indenture to
         such extent as shall be necessary to permit or facilitate the
         defeasance and discharge of any series of Securities pursuant to
         Sections 401, 1402 and 1403; provided that any such action shall not
         adversely affect the interests of the Holders of Securities of such
         series and any related coupons or any other series of Securities in any
         material respect; or

         series of the Securities; or

                  (12) to comply with the requirements of the Commission in

         the Trust Indenture Act.

                  SECTION 902 Supplemental Indentures with Consent of Holders.

                  With the consent of the Holders of not less than a majority in
principal amount of all Outstanding Securities affected by such supplemental
indenture, with each series voting separately, by Act of said Holders delivered
to the Company and the Trustee, the Company, when authorized by or pursuant to a
Board Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of
modifying in any manner the rights of the Holders of Securities and any related
coupons under this Indenture; provided, however, that no such

                                       67
<PAGE>   77

supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                  (1) change the Stated Maturity of the principal of (or
         premium, if any, on) or any installment of principal of or interest on,
         any Security, subject to the provisions of Section 308; or reduce the
         principal amount thereof or the rate of interest (or change the manner
         of calculation of interest) thereon, or any Additional Amounts with
         respect thereto, or any premium payable upon the redemption thereof, or
         change any obligation of the Company to pay Additional Amounts pursuant
         to Section 1005 (except as contemplated by Section 801(1) and permitted
         by Section 901(1)), or reduce the portion 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 502 or the amount thereof provable in bankruptcy
         pursuant to Section 504, or adversely affect any right of repayment at
         the option of the Holder of any Security, or change any Place of
         Payment where, or the Currency in which, any Security or any premium or
         interest or Additional Amount 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 or repayment
         at the option of the Holder, on or after the Redemption Date or the
         Repayment Date, as the case may be), or adversely affect any right to
         convert or exchange any Security as may be provided pursuant to Section
         301 herein, or

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver with respect to such series (of
         compliance with certain provisions of this Indenture or certain
         defaults hereunder and their consequences) provided for in this
         Indenture, or reduce the requirements of Section 1504 for quorum or
         voting, or

                  (3) modify any of the provisions of this Section, Section 513
         or Section 1006, except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or
         waived without the consent of the Holder of each Outstanding Security
         affected thereby, or

                  (4) modify any of the provisions of this Indenture relating to
         the subordination of the Securities or the definitions related thereto
         as they affect subordination in a manner adverse to the Holders.

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

                  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

                                       68
<PAGE>   78

of Securities of such series with respect to such covenant or other provision,
shall be deemed not to affect the rights under this Indenture of the Holders of
Securities of any other series.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders at the
close of Business on such record date, or their duly designated proxies, and
only such Persons, shall be entitled to consent to such supplemental indenture,
whether or not such Holders remain Holders after such record date; provided that
unless such consent shall have become effective by virtue of the requisite
percentage having been obtained prior to the date which is 90 days after such
record date, any such consent previously given shall automatically and without
further action by any Holder be cancelled and of no further effect.

                  SECTION 903 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 (subject to the provisions
of Article Six hereof), 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 affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

                  SECTION 904 Effect of Supplemental Indentures.

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

                  SECTION 905 Conformity With Trust Indenture Act.

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

                  SECTION 906 Reference in Securities to Supplemental
Indentures.

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

                  SECTION 907 Effect on Senior Indebtedness.

                  No supplemental indenture shall adversely affect the rights of
any holder of Senior Indebtedness under Article Sixteen without the consent of
such holder.

                                  ARTICLE TEN

                                    COVENANTS

                  SECTION 1001 Payment of Principal, Premium, if any, and
Interest.

                  The Company covenants and agrees for the benefit of the
Holders of each series of Securities that it will duly and punctually pay the
principal of (and premium, if any) and interest and Additional Amounts, if any,
on the Securities of that series in accordance with the terms of such series of
Securities, any coupons appertaining thereto and this Indenture. Any interest
due on Bearer Securities on or before Maturity, other than Additional Amounts,
if any, payable as provided in Section 1004 in respect of principal of (or
premium, if any, on) such a Security, shall be payable only upon presentation
and surrender of the several coupons for such interest installments as are
evidenced thereby as they severally mature. Unless otherwise specified with
respect to Securities of any series pursuant to Section 301, at the option of
the Company, all payments of principal may be paid by check to the registered
Holder of the Registered Security or other person entitled thereto against
surrender of such Security or wire transfer to an account in the United States
maintained by the Payee.

                  SECTION 1002 Maintenance of Office or Agency.

                  If Securities of a series are issuable only as Registered
Securities, the Company shall maintain in each Place of Payment for any series
of Securities an office or agency where Securities of that series may be
presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange, where Securities of that
series that are convertible or exchangeable may be surrendered for conversion or
exchange, as applicable, 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 (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment, where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange, where Securities of that series that are convertible
or exchangeable may be surrendered for conversion or exchange, as applicable,
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served and where Bearer Securities of that
series and related coupons may be presented or surrendered for payment in the
circumstances described in the following paragraph (and not otherwise), (B)
subject to any laws or regulations applicable thereto, in a Place of Payment for
that series which is located outside the United States, an office or agency
where Securities of that series and related coupons may be presented and
surrendered for

                                       70
<PAGE>   80

payment; provided, however, that if the Securities of that series are listed on
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 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 (C)
subject to any laws or regulations applicable thereto, in a Place of Payment for
that series located outside the United States an office or agency where any
Registered Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for exchange, where
Securities of that series that are convertible or exchangeable may be
surrendered for conversion or exchange, as applicable, 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 each 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 may be presented and surrendered for payment at
the offices specified in the Security, in London, England, and the Company
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands, and the Company hereby appoints the Trustee its
agent to receive all such presentations, surrenders, notices and demands.

                  Unless otherwise specified with respect to any Securities
pursuant to Section 301, 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 or by check mailed to any address in the United States or by transfer to
an account maintained with a bank located in the United States; provided,
however, that, if the Securities of a series are payable in Dollars, payment of
principal of (and premium, if any) and interest, if any, on any Bearer Security
shall be made at the office of the Company's Paying Agent 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 outside the United States maintained for such purpose by the
Company in accordance with this Indenture, is illegal or effectively precluded
by exchange controls or other similar restrictions.

                  The Company may from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all of such purposes, and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in accordance with the requirements set forth above for
Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency. Unless otherwise specified with
respect to any Securities pursuant to Section 301 with respect to a series of
Securities, the Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Company in the Borough of Manhattan,

                                       71
<PAGE>   81

The City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

                  Unless otherwise specified with respect to any Securities
pursuant to Section 301, if and so long as the Securities of any series (i) are
denominated in a currency other than Dollars or (ii) may be payable in a
currency other than Dollars, or so long as it is required under any other
provision of the Indenture, then the Company will maintain with respect to each
such series of Securities, or as so required, at least one Exchange Rate Agent.

                  SECTION 1003 Money for Securities Payments to be Held in
Trust.

                  If the Company shall at any time act as its own Paying Agent
with respect to any series of any Securities and any related coupons, it will,
on or before each due date of the principal of (or premium, if any) or interest,
if any, on any of the Securities of that series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the principal
of (and premium, if any) and interest, if any, on Securities of such series so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided, and will promptly notify the Trustee of its action or
failure so to act.

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

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

                  Except as otherwise provided in the Securities of any series,
any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of (or premium, if any) or
interest, if any, on any Security of any series and remaining unclaimed for two
years after such principal, premium or interest has become due and payable shall
be paid to the Company upon Company Request or (if then held by the Company)
shall be discharged from such trust; and the

                                       72
<PAGE>   82

Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment of such principal, premium or interest on any
Security, without interest thereon, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper in each Place of Payment for such series, or mailed to each Holder of
Registered Securities of such series, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

                  SECTION 1004 Corporate Existence.

                  Subject to Article Eight, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence and material rights and franchises (charter and statutory);
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Company shall determine that the preservation thereof
is no longer necessary or desirable in the conduct of the business of the
Company; and provided further, however, that the foregoing shall not prohibit a
sale, transfer or conveyance of a Subsidiary or any of its assets in compliance
with the terms of the Indenture.

                  SECTION 1005 Additional Amounts.

                  If any Securities of a series provide for the payment of
Additional Amounts, the Company will pay to the Holder of a Security of such
series or any coupon appertaining thereto Additional Amounts as may be specified
as contemplated by Section 301. Whenever in this Indenture there is mentioned,
in any context, the payment of the principal of (or premium, if any) or
interest, if any, on any Security of any series or payment of any related coupon
or the net proceeds received on the sale or exchange of any Security of any
series, such mention shall be deemed to include mention of the payment of
Additional Amounts provided by the terms of such series established pursuant to
Section 301 to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms and express mention
of the payment of Additional Amounts (if applicable) in any provisions hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

                  Except as otherwise specified as contemplated by Section 301,
if the Securities of a series provide for the payment of Additional Amounts, at
least 10 days prior to the first Interest Payment Date with respect to that
series of Securities (or if the Securities of that series will not bear interest
prior to Maturity, the first day on which a payment of principal and any premium
is made), and at least 10 days prior to each date of payment of principal,
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate, the Company will furnish the
Trustee and the Company's principal Paying Agent or Paying Agents, if other than

                                       73
<PAGE>   83

the Trustee, with an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal, premium or
interest on the Securities of that series shall be made to Holders of Securities
of that series or any related coupons who are not United States persons without
withholding for or on account of any tax, assessment or other governmental
charge described in the Securities of the series. If any such withholding shall
be required, then such Officers' Certificate shall specify by country the
amount, if any, required to be withheld on such payments to such Holders of
Securities of that series or related coupons and the Company will pay to the
Trustee or such Paying Agent the Additional Amounts required by the terms of
such Securities. In the event that the Trustee or any Paying Agent, as the case
may be, shall not so receive the above-mentioned certificate, then the Trustee
or such Paying Agent shall be entitled (i) to assume that no such withholding or
deduction is required with respect to any payment of principal or interest with
respect to any Securities of a series or related coupons until it shall have
received a certificate advising otherwise and (ii) to make all payments of
principal and interest with respect to the Securities of a series or related
coupons without withholding or deductions until otherwise advised. The Company
covenants to indemnify the Trustee and any Paying Agent for, and to hold them
harmless against, any loss, liability or expense reasonably incurred without
negligence or bad faith on their part arising out of or in connection with
actions taken or omitted by any of them in reliance on any Officers' Certificate
furnished pursuant to this Section or in reliance on the Company's not
furnishing such an Officers' Certificate.

                  SECTION 1006 Statement as to Compliance.

                  The Company will deliver to the Trustee, within 120 days after
the end of each fiscal year, a brief certificate from the principal executive
officer, principal financial officer or principal accounting officer as to his
or her knowledge of the Company's compliance with all conditions and covenants
under this Indenture and, if the Company is in default, specifying all such
defaults and the nature and status thereof of which he or she may have
knowledge. For purposes of this Section 1006, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

                  SECTION 1007 Waiver of Certain Covenants.

                  As specified pursuant to Section 301(15) for Securities of any
series, the Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 1006 and, as specified pursuant to
Section 301(15) for Securities of any series, in any covenants of the Company
added to Article Ten pursuant to Section 301(14) or Section 301(15) in
connection with the Securities of a series, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities, by Act of such Holders, waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

                  SECTION 1101 Applicability of Article.

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

                  SECTION 1102 Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution. In case of any redemption at the
election of the Company of less than all of the Securities of any series, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee in writing of such Redemption Date and of the principal amount of
Securities of such series to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

                  SECTION 1103 Selection by Trustee of Securities to be
Redeemed.

                  If less than all the Securities of any series issued on the
same day with the same terms 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 issued on such date
with the same terms not previously called for redemption, by such method as the
Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

                  The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

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

                                       75
<PAGE>   85

                  SECTION 1104 Notice of Redemption.

                  Notice of redemption shall be given in the manner provided in
Section 106, not less than 30 days nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified by the terms of such series
established pursuant to Section 301, to each Holder of Securities to be
redeemed, but failure to give such notice in the manner herein provided to the
Holder of any Security designated for redemption as a whole or in part, or any
defect in the notice to any such Holder, shall not affect the validity of the
proceedings for the redemption of any other such Security or portion thereof.

                  Any notice that is mailed to the Holders of Registered
Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the Holder receives the notice.

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price and accrued interest, if any, to the
         Redemption Date payable as provided in Section 1106,

                  (3) if less than all Outstanding Securities of any series are
         to be redeemed, the identification (and, in the case of partial
         redemption, the principal amount) 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 will
         receive, without a charge, a new Security or Securities of authorized
         denominations for the principal amount thereof remaining unredeemed,

                  (5) that on the Redemption Date, the Redemption Price and
         accrued interest, if any, to the Redemption Date payable as provided in
         Section 1106 will become due and payable upon each such Security, or
         the portion thereof, to be redeemed and, if applicable, that interest
         thereon shall cease to accrue on and after said date,

                  (6) the Place or Places of Payment where such Securities,
         together in the case of Bearer Securities with all coupons appertaining
         thereto, if any, maturing after the Redemption Date, are to be
         surrendered for payment of the Redemption Price and accrued interest,
         if any,

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

                  (8) 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 date fixed for
         redemption or the amount of

                                       76
<PAGE>   86

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

                  (9) 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 305
         or otherwise, the last date, as determined by the Company, on which
         such exchanges may be made, and

                  (10) the CUSIP number of such Security, if any.

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

                  SECTION 1105 Deposit of Redemption Price.

                  On or prior to any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, which it may not do in the case of a sinking fund payment under
Article Twelve, segregate and hold in trust as provided in Section 1003) an
amount of money in the Currency in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series and except, if applicable, as provided in Sections
312(b), 312(d) and 312(e)) sufficient to pay on the Redemption Date the
Redemption Price of, and (unless otherwise specified pursuant to Section 301)
accrued interest on, all the Securities or portions thereof which are to be
redeemed on that date.

                  SECTION 1106 Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the
Securities of any series so to be redeemed shall, on the Redemption Date, become
due and payable at the Redemption Price therein specified in the Currency in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if
applicable, as provided in Sections 312(b), 312(d) and 312(e)) (together with
accrued interest, if any, to the Redemption Date), and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued interest, if any) such Securities shall if the same were
interest-bearing cease to bear interest and the coupons for such interest
appertaining to any Bearer Securities so to be redeemed, except to the extent
provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, 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 installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in

                                       77
<PAGE>   87

Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of coupons for such interest; and provided
further that installments of interest on Registered Securities whose Stated
Maturity is prior to (or, if specified pursuant to Section 301, on) the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
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 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 the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
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 Redemption Price shall, until paid,
bear interest from the Redemption Date at the rate of interest set forth in such
Security or, in the case of an Original Issue Discount Security, at the Yield to
Maturity of such Security.

                  SECTION 1107 Securities Redeemed in Part.

                  Any Registered Security which is to be redeemed only in part
(pursuant to the provisions of this Article or of Article Twelve) shall be
surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing) and the Company shall execute and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge a new Security or Securities of the same series, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered. However, if less than all the Securities of any
series with differing issue dates, interest rates and stated maturities are to
be redeemed, the Company in its sole discretion shall select the particular
Securities to be redeemed and shall notify the Trustee in writing thereof at
least 45 days prior to the relevant redemption date.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

                  SECTION 1201 Applicability of Article.

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

            The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of such Securities of any series is herein referred to as an "optional
sinking fund payment". If provided for by the terms of any Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to
reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

                  SECTION 1202 Satisfaction of Sinking Fund Payments with
Securities.

                  Except as otherwise specifically contemplated by Section 301
for Securities of such series, the Company may, in satisfaction of all or any
part of any mandatory sinking fund payment with respect to the Securities of a
series, (1) deliver Outstanding Securities of such series (other than any
previously called for redemption) together in the case of any Bearer Securities
of such series with all unmatured coupons appertaining thereto and (2) apply as
a credit Securities of such 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, as provided for by the terms of such Securities; provided that
such Securities so delivered or applied as a credit have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the applicable Redemption Price specified in such Securities for
redemption through operation of the sinking fund and the amount of such
mandatory sinking fund payment shall be reduced accordingly.

                  SECTION 1203 Redemption of Securities for Sinking Fund.

                  Not less than 60 days prior to each sinking fund payment date
for Securities of any series, the Company will deliver to the Trustee an
Officers' Certificate specifying the amount of the next ensuing mandatory
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 in the
Currency in which the Securities of such series are payable (except as otherwise
specified pursuant to Section 301 for the Securities of such series and except,
if applicable, as provided in Sections 312(b), 312(d) and 312(e)) and the
portion thereof, if any, which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 1202, and the optional amount, if
any, to be added in cash

                                       79
<PAGE>   89

to the next ensuing mandatory sinking fund payment, and will also deliver to the
Trustee any Securities to be so delivered and credited. If such Officers'
Certificate shall specify an optional amount to be added in cash to the next
ensuing mandatory sinking fund payment, the Company shall thereupon be obligated
to pay the amount therein specified. 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 1103 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 1104. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

                  SECTION 1301 Applicability of Article.

                  Repayment of Securities of any series before their Stated
Maturity at the option of Holders thereof shall be made in accordance with the
terms of such Securities and (except as otherwise specified by the terms of such
series established pursuant to Section 301) in accordance with this Article.

                  SECTION 1302 Repayment of Securities.

                  Securities of any series subject to repayment in whole or in
part at the option of the Holders thereof will, unless otherwise provided in the
terms of such Securities, be repaid at the Repayment Price thereof, together
with interest, if any, thereon accrued to the Repayment Date specified in or
pursuant to the terms of such Securities. The Company covenants that on or
before the Repayment Date it will deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money in the Currency in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if
applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay
the Repayment Price of, and (unless otherwise specified pursuant to Section 301)
accrued interest on, all the Securities or portions thereof, as the case may be,
to be repaid on such date.

                  SECTION 1303 Exercise of Option.

                  Securities of any series subject to repayment at the option of
the Holders thereof will contain an "Option to Elect Repayment" form on the
reverse of such Securities. To be repaid at the option of the Holder, any
Security so providing for such repayment, with the "Option to Elect Repayment"
form on the reverse of such Security duly completed by the Holder (or by the
Holder's attorney duly authorized in writing), must be received by the Company
at the Place of Payment therefor specified in the terms of such Security (or at
such other place or places of which the Company shall from time

                                       80
<PAGE>   90

to time notify the Holders of such Securities) not earlier than 45 days nor
later than 30 days prior to the Repayment Date. If less than the entire
Repayment Price of such Security is to be repaid in accordance with the terms of
such Security, the portion of the Repayment Price of such Security to be repaid,
in increments of the minimum denomination for Securities of such series, and the
denomination or denominations of the Security or Securities to be issued to the
Holder for the portion of such Security surrendered that is not to be repaid,
must be specified. Any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part. Except as otherwise may be provided by the terms of any
Security providing for repayment at the option of the Holder thereof, exercise
of the repayment option by the Holder shall be irrevocable unless waived by the
Company.

                  SECTION 1304 When Securities Presented For Repayment Become
Due and Payable.

                  If Securities of any series providing for repayment at the
option of the Holders thereof shall have been surrendered as provided in this
Article and as provided by or pursuant to the terms of such Securities, such
Securities or the portions thereof, as the case may be, to be repaid shall
become due and payable and shall be paid by the Company on the Repayment Date
therein specified, and on and after such Repayment Date (unless the Company
shall default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the Repayment Price of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that installments of interest on
Registered Securities whose Stated Maturity is prior to (or, if specified
pursuant to Section 301, on) the Repayment Date shall be payable (but without
interest thereon, unless the Company shall default in the payment thereof) to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

                  If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 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

                                       81
<PAGE>   91

save each of them and any Paying Agent harmless. If thereafter the Holder of
such Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made as provided
in the preceding sentence, 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 the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of those
coupons.

                  If any Security surrendered for repayment shall not be so
repaid upon surrender thereof, the Repayment Price shall, until paid, bear
interest from the Repayment Date at the rate of interest set forth in such
Security or, in the case of an Original Issue Discount Security, at the Yield to
Maturity of such Security.

                  SECTION 1305 Securities Repaid in Part.

                  Upon surrender of any Registered Security which is to be
repaid in part only, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge
and at the expense of the Company, a new Registered Security or Securities of
the same series, of any authorized denomination specified by the Holder, in an
aggregate principal amount equal to and in exchange for the portion of the
principal of such Security so surrendered which is not to be repaid.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

                  SECTION 1401 Applicability of Article; Company's Option to
Effect Defeasance or Covenant Defeasance.

                  If pursuant to Section 301 provision is made for either or
both of (a) defeasance of the Securities of or within a series under Section
1402 or (b) covenant defeasance of the Securities of or within a series under
Section 1403, then the provisions of such Section or Sections, as the case may
be, together with the other provisions of this Article (with such modifications
thereto as may be specified pursuant to Section 301 with respect to any
Securities), shall be applicable to such Securities and any coupons appertaining
thereto, and the Company may at its option by Board Resolution, at any time,
with respect to such Securities and any coupons appertaining thereto, elect to
have Section 1402 (if applicable) or Section 1403 (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 1402 Defeasance and Discharge.

                  Upon the Company's exercise of the above option applicable to
this Section with respect to any Securities of or within a series, the Company
shall be deemed to have been discharged from its obligations with respect to
such Outstanding Securities and any coupons appertaining thereto on the date the
conditions set forth in Section 1404

                                       82
<PAGE>   92

are satisfied (hereinafter, "defeasance"). For this purpose, such defeasance
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) 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
execute proper instruments acknowledging the same), except for the following
which shall survive until otherwise terminated or discharged hereunder: (A) the
rights of Holders of such Outstanding Securities and any coupons appertaining
thereto to receive, solely from the trust fund described in Section 1404 and as
more fully set forth in such Section, payments in respect of the principal of
(and premium, if any) and interest, if any, on such Securities and any coupons
appertaining thereto when such payments are due, (B) the Company's obligations
with respect to such Securities under Sections 305, 306, 1002 and 1003 and with
respect to the payment of Additional Amounts, if any, on such Securities as
contemplated by Section 1004 with respect to the rights, if any, of the holders
of such Securities to require the Company to repay such Securities as
contemplated by Article 13 and with respect to the rights, if any, of holders to
convert or exchange such Securities into other Securities, (C) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and (D) this
Article. Subject to compliance with this Article Fourteen, the Company may
exercise its option under this Section notwithstanding the prior exercise of its
option under Section 1403 with respect to such Securities and any coupons
appertaining thereto. Money and securities held in trust pursuant to this
Section 1402 shall not be subject to Article Sixteen.

                  SECTION 1403 Covenant Defeasance.

                  Upon the Company's exercise of the above option applicable to
this Section with respect to any Securities of or within a series, the Company
shall be released from its obligations under Section 1005 if specified pursuant
to Section 301, from its obligations under any covenant with respect to such
Outstanding Securities and any coupons appertaining thereto on and after the
date the conditions set forth in Section 1404 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 [restrictive covenants that may
be added], or such other covenant, but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to such Outstanding 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 501(4) or 501(7) or
otherwise except as specified in accordance with Section 301, as the case may
be, but, except as specified

                                       83
<PAGE>   93

above, the remainder of this Indenture and such Securities and any coupons
appertaining thereto shall be unaffected thereby.

                  SECTION 1404 Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of
Section 1402 or Section 1403 to any Outstanding Securities of or within a series
and any coupons appertaining thereto:

                  (a) The Company shall irrevocably have deposited or caused to
be deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount (in such Currency in which such Securities and any
coupons appertaining thereto are then specified as payable at Stated Maturity),
or (2) Government Obligations applicable to such Securities and coupons
appertaining thereto (determined on the basis of the Currency in which such
Securities and coupons appertaining thereto are then specified as payable at
Stated Maturity) which through the scheduled payment of principal and interest
in respect thereof in accordance with their terms will provide, not later than
one day before the due date of any payment of principal of (and premium, if any)
and interest, if any, on such Securities and any coupons appertaining thereto,
money in an amount, or (3) a combination thereof in an amount, sufficient, in
the opinion of a nationally recognized firm of independent public accountants or
nationally recognized independent investment banking firm expressed in a written
certification thereof delivered to the Trustee, to pay and discharge, and which
shall be applied by the Trustee (or other qualifying trustee) to pay and
discharge, (i) the principal of (and premium, if any) and interest, if any, on
such Outstanding Securities and any coupons appertaining thereto on the Stated
Maturity of such principal or installment of principal or interest and (ii) any
mandatory sinking fund payments or analogous payments applicable to such
Outstanding Securities and any coupons appertaining thereto on the day on which
such payments are due and payable in accordance with the terms of this Indenture
and of such Securities and any coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
a breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound.

                  (c) No Default or Event of Default with respect to such
Securities and any coupons appertaining thereto shall have occurred and be
continuing on the date of such deposit or, insofar as Sections 501(5) and 501(6)
are concerned, at any time during the period ending on the 91st day after the
date of such deposit (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 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has

                                       84
<PAGE>   94

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
Outstanding 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, in the
same manner and at the same times as would have been the case if such defeasance
had not occurred.

                  (e) In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding 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 1402 or the covenant
defeasance under Section 1403 (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 1402 or Section 1403 (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) Notwithstanding any other provisions of this Section, 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 pursuant to Section 301.

                  SECTION 1405 Deposited Money and Government Obligations to Be
Held in Trust; Other Miscellaneous Provisions.

                  Subject to the provisions of the last paragraph of Section
1003, all money and Government Obligations (or other property as may be provided
pursuant to Section 301) (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
1405, the "Trustee") pursuant to Section 1404 in respect of any Outstanding
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 (and premium, if any) and interest,
if any, but such money need not be segregated from other funds except to the
extent required by law.

                                       85
<PAGE>   95

                  Unless otherwise specified with respect to any Security
pursuant to Section 301, if, after a deposit referred to in Section 1404(a) has
been made, (a) the Holder of a Security in respect of which such deposit was
made is entitled to, and does, elect pursuant to Section 312(b) or the terms of
such Security to receive payment in a Currency other than that in which the
deposit pursuant to Section 1404(a) has been made in respect of such Security,
or (b) a Conversion Event occurs as contemplated in Section 312(d) or 312(e) or
by the terms of any Security in respect of which the deposit pursuant to Section
1404(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 (and 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 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 in effect on the second Business Day prior to
each payment date, except, with respect to a Conversion Event, for such Currency
in effect (as nearly as feasible) at the time of the Conversion Event.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the Government
Obligations deposited pursuant to Section 1404 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of such Outstanding Securities and any
coupons appertaining thereto.

                  Anything in this Article to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in Section 1404 which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect a
defeasance or covenant defeasance, as applicable, in accordance with this
Article.

                  SECTION 1501 Purposes For Which Meetings May Be Called.

                  If Securities of a series are issuable as Bearer Securities, a
meeting of Holders of Securities of such series may be called at any time and
from time to time pursuant to this Article to make, give or take any request,
demand, authorization, direction, notice, consent, waiver or other action

                  The Company may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 1501, to be held

constitute a quorum.

                  Except as limited by the proviso to Section 902, any
resolution presented to a meeting or adjourned meeting duly reconvened at which
a quorum is present as aforesaid may be adopted by the affirmative vote of the
Holders of a majority in principal amount of the Outstanding Securities of that
series; provided, however, that, except as limited by the proviso to Section
902, any resolution with respect to any request, demand,

                                       87
<PAGE>   97

authorization, direction, notice, consent, waiver or other action which this
Indenture expressly provides may be made, given or taken by the Holders of a
specified percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Securities of that series.

                  Any resolution passed or decision taken at any meeting of
Holders of Securities of any series duly held in accordance with this Section
shall be binding on all the Holders of Securities of such series and the related
coupons, whether or not present or represented at the meeting.

                  Notwithstanding the foregoing provisions of this Section 1504,
if any action is to be taken at a meeting of Holders of Securities of any series
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

                  (a) there shall be no minimum quorum requirement for such
         meeting; and

                  (b) the principal amount of the Outstanding Securities of such
         series that vote in favor of such request, demand, authorization,
         direction, notice, consent, waiver or other action shall be taken into
         account in determining whether such request, demand, authorization,
         direction, notice, consent, waiver or other action has been made, given
         or taken under this Indenture.

                  SECTION 1505 Determination of Voting Rights; Conduct and
Adjournment of Meetings.

                  (a) Notwithstanding any provisions of this Indenture, the
Company may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of a series in regard to proof of the holding
of Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the Person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 104 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 104 or
other proof.

                                       88
<PAGE>   98

                  (b) The Company shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
Holders of Securities as provided in Section 1502(b), in which case the Holders
of Securities of the series calling the meeting shall in like manner appoint a
temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Persons entitled to vote a majority in
principal amount of the Outstanding Securities of such series represented at the
meeting.

                  (c) At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

                  (d) Any meeting of Holders of Securities of any series duly
called pursuant to Section 1502 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of
the Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

                  SECTION 1506 Counting Votes and Recording Action of Meetings.

                  The vote upon any resolution submitted to any meeting of
Holders of Securities of any series shall be by written ballots on which shall
be subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
Series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the fact, setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the former to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                           SUBORDINATION OF SECURITIES

                  SECTION 1601 Agreement to Subordinate.

                  Except as otherwise specified pursuant to Section 301, the
Company, for itself, its successors and assigns, covenants and agrees, and each
Holder of Securities by his acceptance thereof, likewise covenants and agrees,
that the payment of the principal of (and premium, if any) and interest, if any,
on each and all of the Securities is hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, in right of payment to the prior
payment in full of all Senior Indebtedness.

                  SECTION 1602 Distribution on Dissolution, Liquidation and
Reorganization; Subrogation of Securities.

                  Except as otherwise specified pursuant to Section 301, upon
any distribution of assets of the Company upon any dissolution, winding up,
liquidation or reorganization of the Company, whether in bankruptcy, insolvency,
reorganization or receivership proceedings or upon an assignment for the benefit
of creditors or any other marshalling of the assets and liabilities of the
Company or otherwise (subject to the power of a court of competent jurisdiction
to make other equitable provision reflecting the rights conferred in this
Indenture upon the Senior Indebtedness and the holders thereof with respect to
the Securities and the holders thereof by a lawful plan of reorganization under
applicable bankruptcy law):

                  (a) the holders of all Senior Indebtedness shall be entitled
         to receive payment in full of the principal thereof (and premium, if
         any) and interest due thereon before the Holders of the Securities are
         entitled to receive any payment upon the principal (or premium, if any)
         or interest, if any, on indebtedness evidenced by the Securities;

                  (b) any payment or distribution of assets of the Company of
         any kind or character, whether in cash, property or securities, to
         which the Holders of the Securities or the Trustee would be entitled
         except for the provisions of this Article Sixteen shall be paid by the
         liquidating trustee or agent or other person making such payment or
         distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, directly to the holders of Senior
         Indebtedness or their representative or representatives or to the
         trustee or trustees under any indenture under which any instruments
         evidencing any of such Senior Indebtedness may have been issued,
         ratably according to the aggregate amounts remaining unpaid on account
         of the principal of (and premium, if any) and interest on the Senior
         Indebtedness held or represented by each, to the extent necessary to
         make payment in full of all Senior Indebtedness remaining unpaid, after
         giving effect to any concurrent payment or distribution to the holders
         of such Senior Indebtedness; and

                                       90
<PAGE>   100
                  (c) in the event that, notwithstanding the foregoing, any
         payment or distribution of assets of the Company of any kind or
         character, whether in cash, property or securities, shall be received
         by the Trustee or the Holders of the Securities before all Senior
         Indebtedness is paid in full, such payment or distribution shall be
         paid over, upon written notice to the Trustee, to the holder of such
         Senior Indebtedness or their representative or representatives or to
         the trustee or trustees under any indenture under which any instrument
         evidencing any of such Senior Indebtedness may have been issued,
         ratably as aforesaid, for application to payment of all Senior
         Indebtedness remaining unpaid until all such Senior Indebtedness shall
         have been paid in full, after giving effect to any concurrent payment
         or distribution to the holders of such Senior Indebtedness.

                  Subject to the payment in full of all Senior Indebtedness, the
Holders of the Securities shall be subrogated to the rights of the holders of
Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to Senior Indebtedness until the principal
of (and premium, if any) and interest, if any, on the Securities shall be paid
in full and no such payments or distributions to the Holders of the Securities
of cash, property or securities otherwise distributable to the holders of Senior
Indebtedness shall, as between the Company, its creditors other than the holders
of Senior Indebtedness, and the Holders of the Securities be deemed to be a
payment by the Company to or on account of the Securities. It is understood that
the provisions of this Article Sixteen are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities, on the
one hand, and the holders of the Senior Indebtedness, on the other hand. Nothing
contained in this Article Sixteen or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as between the Company, its creditors
other than the holders of Senior Indebtedness, and the Holders of the
Securities, the obligation of the Company, which is unconditional and absolute,
to pay to the Holders of the Securities the principal of (and premium, if any)
and interest, if any, on the Securities as and when the same shall become due
and payable in accordance with their terms, or to affect the relative rights of
the Holders of the Securities and creditors of the Company other than the
holders of Senior Indebtedness, nor shall anything herein or in the Securities
prevent the Trustee or the Holder of any Security from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, under this Article Sixteen of the holders of Senior
Indebtedness in respect of cash, property or securities of the Company received
upon the exercise of any such remedy. Upon any payment or distribution of assets
of the Company referred to in this Article Sixteen, the Trustee, subject to the
provisions of Section 601, shall be entitled to rely upon a certificate of the
liquidating trustee or agent or other person making any distribution to the
Trustee for the purpose of ascertaining the Persons entitled to participate in
such distribution, the holders of Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
Sixteen.

                  The Trustee, however, shall not be deemed to owe any fiduciary
duty to the holders of Senior Indebtedness. The Trustee shall not be liable to
any such holder if it shall pay over or distribute to or on behalf of Holders of
Securities or the Company

                                       91
<PAGE>   101
moneys or assets to which any holder of Senior Indebtedness shall be entitled by
virtue of this Article Sixteen.

                  If the Trustee or any Holder of Securities does not file a
proper claim or proof of debt in the form required in any proceeding referred to
above prior to 30 days before the expiration of the time to file such claim in
such proceeding, then the holder of any Senior Indebtedness is hereby
authorized, and has the right, to file an appropriate claim or claims for or on
behalf of such Holder of Securities.

                  SECTION 1603 No Payment on Securities in Certain
Circumstances.

                  Except as otherwise specified pursuant to Section 301,

                  (a) Upon the maturity of any Senior Indebtedness by lapse of
         time, acceleration (unless waived, rescinded or annulled) or otherwise,
         or upon any payment default (with or without the giving of notice or
         lapse of time or both, in accordance with the terms of the instrument
         governing such Senior Indebtedness, and without any waiver or
         forgiveness) with respect to any Senior Indebtedness, all amounts
         payable thereon shall first be paid in full, or such Senior
         Indebtedness, before any payment is made, directly or indirectly by set
         off or otherwise, on account of principal of, or interest on, the
         Securities of such series or to acquire any of the Securities of such
         series or on account of the redemption provisions of the Securities of
         such series.

                  (b) Upon a default with respect to any Senior Indebtedness
         (other than under circumstances when the terms of paragraph (a) of this
         Section are applicable), as such default is defined therein or in the
         instrument under which it is outstanding, permitting the holders to
         accelerate the maturity thereof, upon written notice thereof given to
         the Company and the Trustee by or on behalf of holders of such Senior
         Indebtedness ("Default Notice"), then, unless and until such default
         shall have been cured or waived by the holders of such Senior
         Indebtedness or shall have ceased to exist, no direct or indirect
         payment shall be made by the Company with respect to the principal of,
         or interest on, the Securities of such series and the coupons, if any,
         appertaining thereto or to acquire any of such Securities or on account
         of the redemption provisions of the Securities of such series and the
         coupons, if any, appertaining thereto; provided, however, that this
         paragraph (b) shall not prevent the making of any payment (which is not
         otherwise prohibited by paragraph (a)) for more than 179 days after the
         Default Notice shall have been given unless the Senior Indebtedness in
         respect of which such event of default exists has been declared due and
         payable in its entirety, in which case no such payment may be made
         until such acceleration has been rescinded or annulled or such Senior
         Indebtedness has been paid in full.

                  (c) If, notwithstanding the foregoing provisions of this
         Section, any payment on account of principal of, or interest on, the
         Securities of such series or of any coupon appertaining thereto shall
         be received by the Trustee, by and Holder or by any Paying Agent (or,
         if the Company is acting as its own Paying

                                       92
<PAGE>   102
         Agent, money for any such payment is segregated and held in trust),
         then, unless and until such payment is no longer prohibited by this
         Section, such payment (subject to the provisions of Section 1604) shall
         be held in trust for the benefit of the holders of Senior Indebtedness
         and, upon notice to the Trustee or such Paying Agent from the
         representative of the holders of the Senior Indebtedness and pursuant
         to the directions of such representative, shall be paid over or
         delivered to the holders of Senior Indebtedness or their
         representative(s), ratably according to the aggregate amount remaining
         unpaid on account of the principal of and interest on the Senior
         Indebtedness held or represented by each, for application to the
         payment or prepayment of all Senior Indebtedness remaining unpaid to
         the extent necessary to pay all Senior Indebtedness in full in
         accordance with its terms, after giving effect to any concurrent
         payment or distribution or provision therefor to or for the holders of
         Senior Indebtedness. Promptly after becoming aware thereof, the Company
         shall give written notice to the Trustee of any event prohibiting
         payments on account of principal of, or interest on, the Securities of
         any series and any coupons appertaining thereto and, in such event,
         shall provide to the Trustee, in the form of an Officers' Certificate,
         the names and addresses of the holders of such Senior Indebtedness and
         their representative(s), if any, the amount of the Senior Indebtedness
         held by each such holder, any information necessary to calculate the
         daily or other increase in Senior Indebtedness held by such holders and
         any other information which the Trustee may reasonably request to
         comply with this Article. Subject to the provisions of Section 1602
         hereof, in the event that the Trustee or the Paying Agent reasonably
         determines that additional evidence is required with respect to any
         person as a holder of Senior Indebtedness to participate in any payment
         or distribution pursuant to this Article, the Trustee or the Paying
         Agent, as the case may be, may request that such person furnish
         evidence to its reasonable as to the extent such person is entitled to
         participate in such payment or distribution and as to other facts
         pertinent to the rights of such persons under this Article and if such
         evidence is not furnished, the Trustee or the Paying Agent, as the case
         may be, may defer any payment to such person pending judicial
         determination as to the right of such person to receive such payment.

                  SECTION 1604 Payments on Securities Permitted.

                  Nothing contained in this Indenture or in any of the
Securities shall (a) affect the obligation of the Company to make, or prevent
the Company from making, at any time except as provided in Sections 1602 and
1603, payments of principal of (or premium, if any) or interest, if any, on the
Securities or (b) prevent the application by the Trustee of any moneys deposited
with it hereunder to the payment of or on account of the principal of (or
premium, if any) or interest, if any, on the Securities, unless the Trustee
shall have received at its Corporate Trust Office written notice of any event
prohibiting the making of such payment more than two Business Days prior to the
date fixed for such payment.

<PAGE>   103
                  SECTION 1605 Authorization of Holders to Trustee to Effect
Subordination.

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

                  SECTION 1606 Notices to Trustee.

                  Notwithstanding the provisions of this Article or any other
provisions of this Indenture, neither the Trustee nor any Paying Agent (other
than the Company) shall be charged with knowledge of the existence of any Senior
Indebtedness or of any event which would prohibit the making of any payment of
moneys to or by the Trustee or such Paying Agent, unless and until the Trustee
or such Paying Agent shall have received (in the case of the Trustee, at its
Corporate Trust Office) written notice thereof from the Company or from the
holder of any Senior Indebtedness or from the trustee for any such holder,
together with proof satisfactory to the Trustee of such holding of Senior
Indebtedness or of the authority of such trustee; provided, however, that if at
least two Business Days prior to the date upon which by the terms hereof any
such moneys may become payable for any purpose (including, without limitation,
the payment of either the principal (or premium, if any) or interest, if any, on
any Security) the Trustee shall not have received with respect to such moneys
the notice provided for in this Section 1606, then, anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to
receive such moneys and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary, which may be
received by it within two Business Days prior to such date. The Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such a notice has been given by a
holder of Senior Indebtedness or a trustee on behalf of any such holder. In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article Sixteen, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article Sixteen and, if such evidence is not furnished,
the Trustee may defer any payment to such Person pending judicial determination
as to the right of such Person to receive such payment.

                  SECTION 1607 Trustee as Holder of Senior Indebtedness.

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article Sixteen in respect of any Senior
Indebtedness at any time held by it to the same extent as any other holder of
Senior Indebtedness and nothing in Section 613 or elsewhere in this Indenture
shall be construed to deprive the Trustee of any of its rights as such holder.

                                       94
<PAGE>   104
                  Nothing in this Article Sixteen shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 606.

                  SECTION 1608 Modifications of Terms of Senior Indebtedness.

                  Any renewal or extension of the time of payment of any Senior
Indebtedness or the exercise by the holders of Senior Indebtedness of any of
their rights under any instrument creating or evidencing Senior Indebtedness,
including, without limitation, the waiver of default thereunder, may be made or
done all without notice to or assent from the Holders of the Securities or the
Trustee. No compromise, alteration, amendment, modification, extension, renewal
or other change of, or waiver, consent or other action in respect of, any
liability or obligation under or in respect of, or of any of the terms,
covenants or conditions of any indenture or other instrument under which any
Senior Indebtedness is outstanding or of such Senior Indebtedness, whether or
not such release is in accordance with the provisions of any applicable
document, shall in any way alter or affect any of the provisions of this Article
Sixteen or of the Securities relating to the subordination thereof.

                  SECTION 1609 Reliance on Judicial Order or Certificate of
Liquidating Agent.

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

                              EMPLOYMENT AGREEMENT

                THIS EMPLOYMENT AGREEMENT (the "Agreement") is made as of May 4,
2000, between WARNER CHILCOTT, INC (the "Company"), and Roger M. Boissonneault
("Executive").

                                    RECITALS

                WHEREAS, Executive is currently employed by Warner Chilcott
Public Limited Company, a public limited company ("Warner");

                WHEREAS, Warner and Galen Holdings plc ("Galen") have entered
into an agreement pursuant to which Galen will exchange all of the outstanding
securities of the Company for ordinary shares in Galen pursuant to a scheme of
arrangement pursuant to Section 201 of the Irish Companies Act (the
"Acquisition");

                WHEREAS, the Company is a subsidiary of Warner;

                WHEREAS, upon consummation of the Acquisition, the Company
desires to employ Executive and Executive desires to be employed by the Company
upon the terms and conditions herein set forth; and

                WHEREAS Executive and Warner are parties to an Employment
Agreement, dated August 1, 1999 (the "Prior Agreement"), which is hereby
superceded and replaced by this Agreement provided that this Agreement shall
only have legal force upon a consummation of the Acquisition and in the event
the Acquisition is not consummated the Prior Agreement shall remain in full
force and effect.

                NOW THEREFORE in consideration of the promises and mutual
covenants herein contained and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

1.       EMPLOYMENT.

        (a)     Executive shall be employed as the Chief Executive Officer of
Galen and agrees to render full time services under this Agreement and to
perform such other duties commensurate with such office.

        (b)     Executive shall perform substantially all of his duties under
this Agreement at the Company's Rockaway, New Jersey office provided, however,
that the Executive may be required to perform incidental services outside the
United States from time to time. Executive may from time to time be required to
perform duties on behalf of any company within the group of companies of which
Galen is a member ("Group Companies"), which duties shall be performed by
Executive without additional compensation or remuneration.

        (c)     Executive hereby accepts such employment and agrees to render
the services described above to the best of his abilities in a diligent,
trustworthy, businesslike and efficient

<PAGE>   2

manner. It shall not be a violation of this Agreement for Executive to serve on
corporate, civic or charitable boards or committees so long as such activities
do not significantly interfere with Executive's commitment to work in accordance
with this Agreement notwithstanding the foregoing, Executive shall not waive or
forfeit his right to have his existing options and warrants become vested due to
the Acquisition (pursuant to Sections 4(h)(i)(i) and (k) of the Prior
Agreement).

        (d)     During the Employment Period (as defined in Section 2 below),
Executive shall be included in any slate of nominees proposed by Galen for
election or reelection, as the case may be, to Galen's Board of Directors.
Executive shall serve as a director of Galen for no additional compensation from
the Company, Warner or Galen. Upon termination of Executive's employment under
this Agreement for any reason, or the expiration of this Agreement, Executive
shall immediately submit his resignation from the Board of Directors of Galen.
During his employment hereunder, Executive shall report to the Board of
Directors of Galen.

        (e)     Upon this Agreement becoming effective, Executive hereby
specifically waives and forfeits all rights and benefits he may have under the
Prior Agreement including all severance and other termination rights which may
accrue solely due to the Acquisition notwithstanding the foregoing, Executive
shall not waive or forfeit his right to have his existing options and warrants
become vested due to the Acquisition (pursuant to Sections 4(h)(i)(j) and (k) of
the Prior Agreement).. In addition, in consideration for the grant of Galen
options as described in Section 3(d), and the retention bonus described in
Section 3(e), Executive hereby waives all right, title and interest that he may
have and effectively consents to the termination of and cancellation of Warner's
obligations to grant to him options to purchase 100,000 shares of common stock
of Warner on May 16, 2000 (the "Pending Options") and the right to a special
incentive bonus to be paid in the event that there is an event that precipitates
an increase in the per share price of Warner between February 28, 2000 ($15.50)
and May 16, 2000. In consideration for such waiver and Executive's covenants and
obligations hereunder, Executive shall be paid a signing bonus (the "Signing
Bonus") as more particularly set out in Appendix A hereto which shall become
payable upon this Employment Agreement becoming effective.

2.      TERM OF EMPLOYMENT. Executive's employment by the Company shall commence
on the date of the consummation of the Acquisition and shall continue unless
terminated as hereinafter provided (the "Employment Period"). Executive may
terminate his employment during the Employment Period with twelve months written
notice to the Company. If the Company gives Executive notice of termination
without cause, Executive shall be entitled to the severance payments provided in
Section 4(d) hereof.

3.      BASE SALARY AND BENEFITS.

        (a)     During the Employment Period, Executive's base salary shall be
$285,000 per annum (the "Base Salary"). The Base Salary shall be subject to
adjustment from time to time in accordance with the compensation policies and
practices of the Company; however, in no case shall Executive's salary be
reduced below $285,000 per annum. The Base Salary shall be

<PAGE>   3

payable in regular installments in accordance with the Company's general payroll
practices and shall be subject to customary withholding.

        (b)     The Company shall reimburse Executive for all reasonable
expenses incurred by him in the course of performing his duties under this
Agreement which are consistent with the Company's policies in effect from time
to time with respect to travel, entertainment and other business expenses. The
parties agree that such expenses shall include, by way of example and not
limitation, cellular telephone service and home fax machine and telephone line.

        (c)     Except for any bonus which is subject to the provisions of
Section 3(e) and (f) hereof, Executive shall be entitled to participate, on a
basis comparable to other key executives of the Company, in any benefit plan,
incentive compensation plan, or program of the Company for which key executives
are or shall become eligible, including, without limitation, pension, 401(k),
life and disability insurance and stock schemes, subject to the approval of the
Remuneration Committee of the Board of Directors of the Company and the terms
and conditions of such plans and schemes.

        (d)     Notwithstanding the limitations contained in Section 3(c)
hereof, in consideration for Executive's agreement to forfeit his rights with
respect to the Pending Options, Executive shall be granted options to purchase
shares of Gershwin in the amount and subject to the terms and conditions set
forth on Appendix A hereto.

        (e)     Notwithstanding the limitations of Section 3(f), on the first
anniversary of the Acquisition (the "Payment Date"), the Executive shall be
eligible to receive a retention bonus in the amount more particularly set out in
Appendix A to this Agreement (the "Retention Bonus"), subject to the following
conditions: (i) the Executive must be employed by the Company on the Payment
Date or Executive's employment is terminated prior to the Payment Date without
cause or for Good Reason (as defined in Sections 4(c) and 4(e) respectively),
(ii) the Chairman determines that Executive has accomplished his assigned task
to successfully integrate Warner into Galen, and (iii) in the event that any
amount paid to the Executive pursuant to this Section 3(e) would not be
deductible for tax purposes to the Company or appropriate Group Company under
U.S. law, the Executive hereby agrees that payment of such amount (or such
portion of such amount which would render the total amount non-tax deductible)
shall be deferred until the earliest time as payment of the whole amount would
be treated as deductible for U.S. tax purposes. Executive shall forfeit the
Retention Bonus if he terminates his employment with the Company other than for
Good Reason prior to the Payment Date.

        (f)     In addition to the Base Salary, Executive shall be eligible to
receive an annual cash bonus in a target amount equal to 50% of his then current
Base Salary. Such bonus shall be provided on such terms and in such amounts, if
any as the Board of Directors of Galen may deem appropriate in its sole
discretion.

        (g)     Executive shall be entitled to vacation time with compensation
of 20 days per annum. Executive shall also be entitled to all paid holidays
given by the Company to its key officers.

4.      TERMINATION.

        (a)     If the Executive shall die during the Employment Period, this
Agreement shall terminate effective as of the date of Executive's death, except
that Executive's surviving spouse or, if none, his estate, shall be entitled to
receive the benefits set forth in Section 4(d) below.

        (b)     At the sole discretion of the Board of Directors of the Company,
Executive's employment may be terminated if the Executive is disabled (as
defined below) and shall have been absent from his duties with the Company on a
full time basis for one hundred and eighty (180) consecutive days, and, within
thirty (30) days after written notice by the Company to do so, the Executive
shall not have returned to the performance of his duties hereunder on a full
time basis. In the event of such termination, the Company shall make to
Executive the payments specified in Section 4(d). As used herein, the term
"disabled" shall (i) mean that Executive is unable, as a result of a medically
determinable physical or mental impairment, to perform the duties and services
of his position, or (ii) have the meaning specified in any disability insurance
policy maintained by the Company, whichever is more favorable to the Executive.

        (c)     The Company may, by notice to Executive, terminate Executive's
employment hereunder for cause. As used herein, "cause" shall mean (i) the
conviction of Executive of a felony (other than violation of a motor vehicle or
moving violation law) or conviction of a misdemeanor if such misdemeanor
involves moral turpitude; or (ii) Executive's voluntary engagement in conduct
constituting larceny, embezzlement, conversion or any other act involving the
misappropriation of any Group Company funds in the course of his employment; or
(iii) the willful refusal (following written notice) to carry out specific
directions of the Board of Directors of Galen, which directions shall be
consistent with the provisions hereof; or (iv) Executive's committing any act of
gross negligence or intentional misconduct in the performance or non-performance
of his duties as an employee of the Company; or (v) any material breach by the
Executive of any material provision of this Agreement (other than for reasons
related only to the business performance of the Company or business results
achieved by Executive). For purposes of this Section 4(c), no act or failure to
act on Executive's part shall be considered to be reason for termination for
cause if done, or omitted to be done, by Executive in good faith and with the
reasonable belief that the action or omission was in the best interests of the
Company. Upon the termination of Executive's employment for cause, the Company
shall pay to Executive (x) his Base Salary accrued through the effective date of
termination, payable at the time such payment is otherwise due and payable
hereunder, and (y) all other amounts and benefits to which Executive is
entitled, including, without limitation, vacation pay and expense reimbursement
amounts accrued to the effective date of termination and amounts and benefits
owing under the terms of any benefit plan of the Company in which Executive
participates and Executive shall not be entitled to any severance payments.

        (d)     The Executive and the Company agree that the Company in its
absolute discretion, may terminate the Executive's employment hereunder without
cause provided, however that in such event Executive shall be entitled to
receive (so long as he executes and delivers the Company's standard form of
release) an amount equal to Executive's then current Base Salary for a period of
twelve months plus all other amounts and benefits to which Executive

<PAGE>   5

is entitled, including without limitation, expense reimbursement amounts accrued
to the effective date of termination and amounts and benefits owing under the
terms of any benefit plan of the Company in which Executive participates (the
"Severance Payment"). The foregoing amounts shall be payable either in equal
monthly installments, payable on or before the last day of each month during the
Severance Period, or in a lump sum payment within ten (10) days after
Executive's last day of active employment. Notwithstanding the foregoing, if
such termination is following a Change in Control, Executive shall be entitled
to receive an amount equal to his then current Base Salary for a period of
eighteen months payable in a lump sum. In addition, Executive shall be entitled
to continue participation in the Company's health and other welfare benefit
plans, at the Company's expense, for the applicable Severance Period. For the
purposes of this Agreement, the "Severance Period" shall mean either 12 months
or 18 months for which the Company is obliged to make payments to the Executive
under this section 4(d) regardless of whether such payments are made in a lump
sum.

        (e)     For purposes of this Agreement, a "Change in Control" shall be
deemed to have occurred if any person (or persons "acting in concert" as defined
in the UK's City Code on Takeovers and Mergers) obtains "control" (as that term
is defined in s.840 of the UK Income and Corporation Taxes Act 1988) of the
Company or Galen and that control is unconditional in all respects; but
excluding any reconstruction or amalgamation of the Company or Galen.

        (f)     Executives employment may be terminated by the Executive,

                (i) for Good Reason. For purposes of this Agreement, "Good
Reason" shall mean: (A) other than as contemplated by Section 1(e) the
assignment to Executive of duties materially inconsistent with Executive's
position (including status, offices, titles, and reporting requirements),
authority, duties or responsibilities as contemplated by Section 1 (a) hereof,
or any other action by the Company or Galen which results in a diminution in
such position, authority, duties or responsibilities, excluding for this purpose
an isolated, insubstantial and inadvertent action not taken in bad faith and
which is remedied by the Company or Galen promptly after receipt of notice
thereof given by Executive; (B) any failure by the Company to comply with any of
the provisions of Section 3 hereof, other than an isolated, insubstantial and
inadvertent failure not occurring in bad faith and which is remedied by the
Company promptly after receipt of notice thereof given by Executive; (C) the
Company's requiring Executive to be based at any office or location other than
as provided in Section 1(b); (D) any purported termination by the Company of
Executive's employment otherwise than as expressly permitted by this Agreement;
or (E) any failure by the Company to obtain an express assumption of this
Agreement by a successor as required pursuant to Section 15 hereof. Upon any
termination pursuant to this subsection (f), Executive shall be entitled to the
payment specified in section 4(d) hereof and to the other rights described
therein (subject to his compliance therewith).

                (ii) by resignation or retirement. If Executive resigns or
retires, this Agreement shall terminate as of the effective date of Executive's
retirement or resignation and thereupon Executive shall be entitled solely to
the payments and benefits set forth in Sections 4(c) and (l).

<PAGE>   6

        (g)     If (i) Executive's employment is terminated pursuant to
sub-sections (a), (b), (d) or (f)(i) of this Section 4; or (ii) a "Change in
Control" of the Company (as defined in Section 4(e) occurs, all stock options,
restricted stock, warrants, deferred compensation and similar benefits which
have not yet become vested on the date of a Change in Control, will become
vested upon such event, and Executive shall be permitted to exercise all such
rights in the eighteen month period immediately following Executive's date of
termination (or such longer date as determined in good faith by the Company in
the event securities laws prevent exercise of such rights in such period)
following any Change of Control, whether or not Executive remains employed with
the Company or terminates his employment in accordance with this subsection (g).
In addition, if a Change in Control occurs, Executive may, after such Change in
Control, terminate his employment with the Company for any reason after the
expiry of sixty (60) days immediately following the effective date of such
Change in Control, in which event Executive shall be entitled to the payments
specified in Section 4(d) above and to the other rights described elsewhere in
this Agreement.

        (h)     Anything in this Agreement to the contrary notwithstanding, in
the event it shall be determined that any payment or distribution by the Company
to or for the benefit of Executive (whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise, but
determined without regard to any additional payments required under this
subsection (h)) (a "Payment") would be subject to the excise tax imposed by
Section 4999 of the Code, or any interest or penalties are incurred by Executive
with respect to such excise tax (such excise tax, together with any such
interest and penalties are hereinafter collectively referred to as the "Excise
Tax"), the Company shall pay to Executive at the time specified in subparagraph
(k) below an additional amount (a "Gross-Up Payment") such that the net amount
of the Gross-Up Payment retained by Executive, after deduction of all federal,
state and local income tax (and any interest and penalties imposed with respect
thereto), employment tax and Excise Tax on the Gross-Up Payment, shall be equal
to the amount of the Excise Tax imposed on such Payment.

        (i)     For purposes of the foregoing subparagraph (h), the proper
amounts, if any, of the Excise Tax and the Gross-Up Payment shall be determined
in the first instance by the Company. Such determination by the Company shall be
communicated in writing by the Company to Executive at least fourteen (14) days
prior to the occurrence of a Change of Control. Within ten (10) days of being
provided with written notice of any such determination, Executive may provide
written notice to the Chairperson of the Compensation Committee of the Board of
Directors of the Company of any disagreement, in which event the amounts, if
any, of the Excise Tax and the Gross-Up Payment shall be determined by an
independent accounting firm mutually selected by the Company and Executive. The
determination of the Company (or in the event of disagreement, the accounting
firm selected) shall be final and nonreviewable.

        (j)     For purposes of determining whether any of the Payments will be
subject to the Excise Tax and the amount of such Excise Tax under subparagraph
(h), the following principles will be applicable:

                (A)     Any payments or benefits received or to be received by
                        Executive in connection with a termination of employment
                        shall be treated as

<PAGE>   7

                        "parachute payments" within the meaning of Section
                        28OG(b)(2) of the Code, and all "excess parachute
                        payments" within the meaning of Section 280G(b)(1) of
                        the Code shall be treated as subject to the Excise Tax
                        unless the accounting firm selected above determines
                        based on reasonable, good faith interpretations
                        concerning the application of Sections 280G and 4999 of
                        the Code, with substantial authority (within the meaning
                        of Section 6662 of the Code), such other payments or
                        benefits (in whole or in part) do not constitute
                        parachute payments, or such excess parachute payments
                        (in whole or in part) represents reasonable compensation
                        for services actually rendered within the meaning of
                        Section 280G(b)(4) of the Code in excess of the base
                        amount within the meaning of Section 280G(b)(3) of the
                        Code; and

                (B)     The value of any non-cash benefits or any deferred
                        payment or benefit shall be determined in accordance
                        with Section 28OG(d)(3) and (4) of the Code. For
                        purposes of determining the amount of the Gross-Up
                        Payment, Executive shall be deemed to pay federal income
                        taxes at the highest marginal rate of tax in the
                        calendar year in which the Gross-Up Payment is to be
                        made and state and local income taxes at the highest
                        marginal rate of tax in the state and locality of
                        Executive's residence on the date of termination, net of
                        the maximum reduction in federal income taxes which
                        could be obtained from deduction of such state and local
                        taxes.

        (k)     The Payments provided for in subparagraph (h) shall be made in a
cash, lump-sum payment, net of any required tax withholdings, upon the later of
(i) the fifth business day following the effective date of termination, or (ii)
the calculation of the amount of the Gross-Up Payment under subparagraph (i).
Any Payment required hereunder that is not made in a timely manner shall bear
interest at a rate equal to the prime rate quoted on the date the payment is
first overdue by Citibank N.A., New York, New York plus two percent until paid.

        (l)     Amounts which are vested benefits or which Executive is
otherwise entitled to receive under any plan, policy, practice or program of or
in any contract or agreement with the Company or any of its affiliated companies
at or subsequent to the date of termination of Executive's employment for any
reason shall be payable in accordance with such plan, policy, practice or
program or contract or agreement except as explicitly modified by this
Agreement.

5.      CONFIDENTIAL INFORMATION.

        (a)     Executive acknowledges and agrees that the information,
observations and data obtained by him concerning Galen or any Group Company
while employed under this Agreement ("Confidential Information") are the
property of Galen and/or the relevant Group Company (as appropriate). Therefore,
Executive agrees to keep secret and retain in the strictest confidence all
Confidential Information, including without limitation, trade "know-how"
secrets, customer lists, pricing policies, operational methods, technical
processes, formulae, inventions and research projects and other business affairs
of the Company, Warner and Galen, learned by

him prior to or after the date of this Agreement, and not to disclose them to
anyone outside the Company, Warner or Galen, either during or after his
employment with the Company, except (i) in the course of performing his duties
hereunder; (ii) with Galen's express written consent; (iii) to the extent that
the Confidential Information becomes generally known to and available for use by
the public other than as a result of Executive's acts or omissions; or (iv)
where required to be disclosed by court order, subpoena or other government
process. If Executive shall be required to make disclosure pursuant to the
provisions of clause (iv) of the preceding sentence, Executive promptly, but in
no event more than 48 hours after learning of such subpoena, court order or
other governmental process, shall notify the Company, by personal delivery or
fax (pursuant to Section 10 hereof), and, at the Company's expense, shall take
all reasonably necessary steps requested by the Company to defend against the
enforcement of such subpoena, court order or other governmental process and
permit the Company to intervene and participate with counsel of its own choice
in any related proceeding.

        (b)     Executive shall deliver to the Company at the termination of his
employment, or at any other time the Company may request, all memoranda, notes,
plans, records, reports, computer tapes, printouts and software and other
documents and data (and copies thereof) relating to the Confidential
Information, Work Product (as defined below) or the business of the Company or
any subsidiary which he may then possess or have under his control.

6.      INVENTIONS AND PATENTS. Executive acknowledges that all inventions,
innovations, improvements, developments, methods, designs, analyses, drawings,
reports and all similar or related information (whether or not patentable) which
relate to the Company's or any of its subsidiaries' actual or anticipated
business, research and development or existing or future products or services
and which are conceived, developed or made by Executive while employed by the
Company or Warner and its subsidiaries ("Work Product") belong to the Company,
Warner or such subsidiary. Executive shall promptly disclose such Work Product
to the Board of Directors of Galen and perform all actions reasonably requested
by the Board of Directors of Galen (whether during or after his employment) to
establish and confirm such ownership (including, without limitation,
assignments, consents, powers of attorney and other instruments).

7.      INDEMNIFICATION. The Company will indemnify Executive and his legal
representatives, to the fullest extent permitted by the laws of the State of
Delaware and the existing by-laws of the Company or any other applicable laws or
the provisions of any other corporate document of the Company, and Executive
shall be entitled to the protection of any insurance policies the Company may
elect to obtain generally for the benefit of its directors and officers, against
all costs, charges and expenses whatsoever incurred or sustained by him or his
legal representatives in connection with any action, suit or proceeding to which
he or his legal representatives may be made a party by reason of him being or
having been a director or officer of the Company or of any of its subsidiaries
or affiliates or actions taken purportedly on behalf of the Company or of any of
its subsidiaries or affiliates. The Company shall advance to Executive the
amount of his expenses incurred in connection with any proceeding relating to
such service or function to the fullest extent legally permissible under
Delaware law. The indemnification and expense reimbursement obligations of the
Company in this Section 7 will continue as to Executive after he ceases to be an
officer of the Company and shall inure to the benefit of his heirs, executors

<PAGE>   9

and administrators. The Company shall not, without Executive's written consent,
cause or permit any amendment of the Company's governing documents which would
affect Executive's rights to indemnification and expense reimbursement
thereunder.

8.      NON-COMPETE. NON-SOLICITATION.

behalf of any person, firm, company or entity and whether on his own account or

other capacity whatsoever, Executive shall not:

        with or endeavor to entice away from the Company or any of the Relevant
        Group Companies any person, firm, company or entity who was a customer
        or potential customer of the Company or any of the Relevant Group
        Companies ;

                (iii)   for the greater of the Severance Period or six months
        following termination in the Relevant Territory be concerned with the
        supply of services/products to any person, firm, company or entity which
        was a customer or potential customer of the Company or any of the
        Relevant Group Companies where such services/products are in competition
        with those services/products supplied by the Company or any of the
        Relevant Group Companies;

                (iv)    for the greater of the Severance Period or six months

        any of the Relevant Group Companies (whether or not such person would
        commit any breach of their contact of employment or engagement by reason
        of leaving the service of such company); and

                (v)     represent himself as being in any way connected with or
        interested in the business of the Company or any of the Relevant Group
        Companies other than in his capacity as a shareholder of any such

        (c)     Nothing contained in Section 8(a) shall prohibit the Executive
