                                ESCROW AGREEMENT

      THIS ESCROW AGREEMENT (this "Agreement") is made and entered into as of
July __, 2003, by and among Mercer Insurance Group, Inc., a Pennsylvania
corporation (the "Company"), Mercer Mutual Insurance Company, a Pennsylvania
corporation ("MMIC"), Sandler O'Neill & Partners, L.P. ("Sandler") and
Wilmington Trust Company ("Wilmington Trust" or the "Escrow Agent").

                                    RECITALS

      A. WHEREAS, the Company, which is the proposed holding company for MMIC,
proposes to sell up to 6,361,111 shares of its common stock (the "Shares"). Of
the Shares, 6,261,111 are being offered, with the assistance of Sandler,
pursuant to a subscription offering, a community offering and possibly a
syndicated community offering (collectively, the "Offerings"), and 100,000 are
being offered to a third party pursuant to a contractual obligation of MMIC (the
"Third Party Offering"). The Offerings are being conducted in connection with
the conversion of MMIC from mutual to stock form and the simultaneous
acquisition of the capital stock of MMIC by the Company pursuant to a Plan of
Conversion (the "Plan") adopted by the Board of Directors of each of MMIC and
the Company on December 13, 2002, as amended and restated on March 19, 2003,
April 15, 2003 and June 18, 2003 (the "Conversion"). The Third Party Offering is
not being conducted in connection with, but will be completed immediately after,
the Conversion. The parties acknowledge that Sandler is not acting as a
financial advisor with respect to, or rendering any assistance to the Company in
connection with, the Third Party Offering.

      B. WHEREAS, the Company intends to offer the Shares pursuant to a
Registration Statement on Form S-1 filed with the Securities and Exchange
Commission on May 1, 2003 (the "Registration Statement").

      C. WHEREAS, the Company desires to establish an escrow account in which
funds received from persons subscribing for or purchasing Shares in the
Offerings and the Third Party Offering including, without limitation, members of
MMIC, the Company's Employee Stock Ownership Plan, and directors, officers and
employees of MMIC or its affiliates, will be deposited pending completion of the
Offerings and the Third Party Offering. Wilmington Trust agrees to serve as the
Escrow Agent to hold funds from, or on behalf of, subscribers or purchasers in
accordance with the terms and conditions of this Agreement. The Company and
Sandler agree to assist the Escrow Agent in administering the Escrow Account
(defined below) and distributing funds held in the Escrow Account.

      D. WHEREAS, the Offerings will be completed if, among other things, the
Company receives subscriptions or purchase orders in the Offerings for at least
4,165,000 Shares, and the Third Party Offering will be completed immediately
after the completion of the Offerings.

      E. WHEREAS, all monies held in the Escrow Account are referred to as the
"Escrow Amount."

      NOW, THEREFORE, in consideration of the foregoing, and for other good and
valuable, consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto, intending legally to be bound, agree as
follows:

                                       1
<PAGE>
I. DESIGNATION AS ESCROW AGENT.

      Subject to the terms and conditions hereof, the Company hereby appoints
Wilmington Trust as Escrow Agent and Wilmington Trust hereby accepts such
appointment.

II. ESTABLISHMENT OF ESCROW ACCOUNT.

      On or prior to the date of the commencement of the Offerings, the parties
shall establish a non-interest bearing escrow account with the Escrow Agent,
which escrow account shall be entitled "Mercer Insurance Group, Inc. Stock
Purchase Account" (the "Escrow Account"). The Company will instruct subscribers
or purchasers to make checks or money orders for subscriptions or purchases
payable to "Wilmington Trust Company, as escrow agent for Mercer Insurance
Group, Inc." Escrow Agent agrees to hold all funds received by it in escrow for
the subscriber or purchaser desiring to purchase Shares in the Offerings or the
Third Party Offering. It is understood that all checks or money orders received
by the Escrow Agent are subject to clearance time, and the funds represented
thereby cannot be drawn upon or invested until such time as the same constitute
good and collected funds. It is also understood that should any checks be
returned to the Escrow Agent as uncollectible, the Escrow Agent is authorized
and instructed to charge expenses incurred by the Escrow Agent on such
uncollected checks to the Company, and the Company and MMIC hereby jointly and
severally agree to pay to the Escrow Agent all such expenses. The Escrow Agent
shall redeposit such checks(s) for collection only upon the verbal or written
instruction of the Company; however, in no instance shall the checks(s) be
presented for collection more than two (2) times. Should the check(s) be
uncollectible after the second presentation, the Escrow Agent shall promptly
notify the Company and hold said check(s) until the subscriber or purchaser has
replaced the same with a cashier's check or money order or such other form of
draft that the Company and the Escrow Agent approve, at which time the Escrow
Agent shall as soon as reasonably practicable return said uncollectible check(s)
to the subscriber or purchaser. In the event the subscriber or purchaser does
not promptly replace said check(s) with a cashier's check or money order or such
other form of draft acceptable to the Escrow Agent and the Company, the Escrow
Agent, at the instruction of the Company, shall return the check(s) to such
subscriber or purchaser. Except pursuant to the Company's instructions, any
checks or money orders received that are made payable to a party other than
"Wilmington Trust Company, as escrow agent for Mercer Insurance Group, Inc."
shall be returned by the Escrow Agent to the subscriber or purchaser submitting
such checks or money orders. In such cases, the Escrow Agent shall promptly
notify the Company of such return.

III. ADMINISTRATION OF FUNDS HELD IN ESCROW.

      Sandler shall receive all stock order forms and checks or money orders
from subscribers or purchasers in the Offerings and shall keep such appropriate
books and records as are required to perform its functions described herein.
Sandler will deliver promptly such checks or money orders to the Escrow Agent
via Federal Express each business day (a "business day" being any day on which
commercial banks are open for general business in Wilmington, Delaware) during
the Offerings for deposit into the Escrow Account together with a copy of the
subscriber's or purchaser's stock order form which sets forth, among other
things, the subscriber's or purchaser's name, address, social security number,
telephone number, number of Shares purchased and the amount paid therefor. The
Company shall receive all stock order forms and checks or money orders from the
subscriber or purchaser in the Third Party Offering and shall keep such
appropriate books and records as are required to perform its functions described
herein. The Company will deliver promptly to the Escrow Agent via Federal
Express such checks or money orders that it receives on any business day (as
defined above) during the Third Party Offering for deposit into the Escrow
Account together with a copy of the subscriber's or purchaser's stock order form
which sets forth, among other things, the subscriber's or purchaser's name,
address, social security number, telephone number, number of Shares purchased
and the amount paid therefor. The Escrow Agent is hereby authorized and
instructed to forward each check or money order it receives from Sandler (with
respect to the Offerings) or the Company (with respect to the Third Party
Offering) for collection, deposit the check or money order in the Escrow Account
and after allowing

                                       2
<PAGE>
for collection of the proceeds of each check or money order in accordance with
Federal Reserve Board regulations, invest the Escrow Amount in accordance with
the terms hereof. Sandler will maintain all subscriber records for the Offerings
until the completion or termination of the Offerings. The Company will maintain
all subscriber records for the Third Party Offering until the completion or
termination of the Third Party Offering.

      The Escrow Agent shall receive all payments for Shares and shall hold all
such payments, together with all investments thereof and all interest
accumulated thereon and proceeds therefrom, in escrow in the Escrow Account, in
all cases upon the terms and conditions set forth in this Agreement and shall
not disburse funds from the Escrow Account except as provided by the terms of
this Agreement. The Escrow Agent is hereby instructed to and shall invest the
Escrow Amount pursuant to and in accordance with written instructions from the
Company that are reasonably acceptable to the Escrow Agent, and in the absence
of such instructions, the Escrow Agent is hereby instructed to and shall, and
hereby agrees to, invest the Escrow Amount only in a Wilmington Trust Premium
Money Market Advantage Account. In its instructions to the Escrow Agent, the
Company may only specify investments permissible under Rule 15c2-4 of the
Securities and Exchange Act of 1934, as amended, and the interpretations thereof
set forth in the NASD Notice to Members 84-7, as reissued or amended. In making
its investments, the Escrow Agent may conclusively rely on any investment
instructions received from the Company, shall have no duty to independently
determine, confirm or verify whether the investments specified in the Company's
instructions comply with the condition set forth in the preceding sentence, and
shall have no liability for making such investments provided it does so in
accordance with the Company's instructions. Subject to the terms of this
Agreement, any income, earnings, proceeds or other gain received on any amounts
invested hereunder shall be deposited into the Escrow Account, will be added to
and increase the Escrow Amount and may be subsequently reinvested in accordance
with the terms hereof, and any losses on any amounts invested hereunder shall
decrease the Escrow Amount.

IV. REJECTION OF PURCHASE ORDERS.

      The Registration Statement provides that the purchase of Shares in the
community and any syndicated community offering is subject to the Company's
approval. The Company agrees to notify the Escrow Agent of which purchase orders
are being rejected by delivering to the Escrow Agent written instructions
pertaining thereto. If a purchase order is rejected, any funds held in the
Escrow Account in connection with such purchase order shall, upon receipt of the
written confirmation from the Company and/or Sandler set forth in, and otherwise
in accordance with, Section VII, be promptly returned to the purchaser, without
any interest thereon, and without deduction, penalties or expense to the
purchaser. Unless a certificate rejecting a purchase order is delivered to the
Escrow Agent pursuant to this Section IV, all purchase orders received in the
community or syndicated community offerings shall be deemed to have been
accepted by the Company.

V. RELEASE OF ESCROW AMOUNT.

      If on the date of closing of the Offerings (as more fully described in the
Registration Statement) the Escrow Agent has received from the Company or
Sandler a certificate stating that the Company has received subscriptions or
purchase orders in the Offerings for at least 4,165,000 Shares and that the
Offerings have closed, then the Escrow Agent is hereby authorized and instructed
to:

                                       3
<PAGE>
      (a) first, upon receipt of the written confirmation from Sandler or the
Company set forth in, and otherwise in accordance with, Section VII, distribute
to purchasers in the community and syndicated community offerings, out of the
Escrow Amount deposited, amounts with respect to purchase orders which the
Company has rejected in accordance with Section IV, without interest thereon;

      (b) second, after making the distributions required in paragraph (a)
above, distribute to itself amounts from the Escrow Amount equal to the amounts
owing to it pursuant to Section XI (if any);

      (c) third, after making the distributions required in paragraphs (a) and
(b) above, pay to Sandler or any selected dealer out of the Escrow Amount an
amount equal to Sandler's or such selected dealer's fees described in the
Registration Statement (upon receipt of instructions from the Company as to such
persons and amounts to be paid); and

      (d) fourth, after making the distributions required in paragraphs (a), (b)
and

      (c) above, pay to the Company the Escrow Amount held by the Escrow Agent
in the Escrow Account.

VI. CANCELLATION OF OFFERINGS.

      If the Company and Sandler give the Escrow Agent written notice that the
Offerings have been canceled, the Escrow Agent shall, upon receipt of the
written confirmation from Sandler and/or the Company set forth in, and otherwise
in accordance with, Section VII, promptly refund to each subscriber or purchaser
in the Offerings and the Third Party Offering, the amount received from the
subscriber or purchaser, without any interest thereon and without deduction,
penalty or expense to the subscriber or purchaser, and Escrow Agent shall notify
the Company and Sandler, in writing, of its distribution of such funds. Any
amounts then remaining in the Escrow Account shall, upon instruction from the
Company to do so, be distributed to or as instructed by the Company. The amounts
returned to each subscriber or purchaser shall be free and clear of any and all
claims of the Escrow Agent, the Company or Sandler, or any creditors of any of
them. In such event, notwithstanding any other provision of this Agreement to
the contrary, the Company and MMIC shall jointly and severally be responsible
for and pay any amounts owing to the Escrow Agent pursuant to Section XI.

VII. DELIVERY OF PAYMENTS OR REFUNDS.

      Upon receiving written confirmation from the Company and/or Sandler of the
amount due to any subscriber or purchaser, the Escrow Agent shall prepare the
necessary checks or money orders. All payments or refunds to be made by the
Escrow Agent to a subscriber or purchaser pursuant to Sections IV, V or VI shall
be forwarded, by first-class mail, to the last known address of the subscriber
or purchaser, as communicated in writing to the Escrow Agent by the Company,
Sandler, or the subscriber or purchaser. All payments to be made by the Escrow
Agent to the Company pursuant to Section V or Section VI shall be forwarded to
the Company at 10 North Highway 31, P.O. Box 278, Pennington, New Jersey 08534,
Attention: Andrew R. Speaker, or issued to such account as the Company shall
direct, in writing.

VIII. THE COMPANY NOT ENTITLED TO ESCROW AMOUNT IN ESCROW UNTIL RELEASED.

      Until a portion of the Escrow Amount is distributed to it pursuant to
Section V or Section VI, the Company acknowledges that (i) it is not entitled to
any portion of the Escrow Amount and (ii) no amounts deposited in the Escrow
Account shall become the property of the Company or be subject to the
liabilities of the Company.

IX. INTEREST.

      Interest, as used in Sections IV, V, VI, VII, and IX of this Agreement,
shall mean investment income, if any, earned on the Escrow Amount, as invested
in accordance with the terms hereof. Interest accrued on the Escrow Amount shall
be reinvested in accordance with the terms hereof and held as part of the Escrow
Amount until distributed pursuant to Section V or Section VI hereof.

X. ESCROW AMOUNT MAY NOT SECURE LOAN.

      Until released in accordance herewith, the Escrow Amount shall at no time
be used directly or indirectly as security for a loan or any other obligation of
the Company and, except as otherwise expressly provided in Section XI hereof,
shall be subject to no right, charge, security interest, lien, setoff or claim
of any kind in favor of the Escrow Agent or any person claiming through the
Escrow Agent.

XI. AUTHORITY OF ESCROW AGENT AND LIMITATION OF LIABILITY.

      (a) In acting hereunder, Escrow Agent shall have only such duties as are
specified herein and no implied duties shall be read into this Agreement, and
Escrow Agent shall not be liable for any act done, or omitted to be done, by it
in the absence of its gross negligence or willful misconduct.

      (b) Escrow Agent may act in reliance upon any writing, instrument, notice
or instruction or signature which it, in good faith, believes to be genuine, and
may assume the validity and accuracy of any statement or assertion contained in
such a writing, instrument, notice or instruction and may assume that any person
purporting to give any writing, instrument, notice, advice or instruction in
connection with the provisions hereof has been duly authorized so to do.

      (c) Escrow Agent shall not be required to use its own funds in the
performance of any of its obligations or duties or the exercise of any of its
rights or powers, and shall not be required to take any action which, in Escrow
Agent's sole and absolute judgment, could involve it in expense or liability
unless furnished with security and indemnity which it deems, in its sole and
absolute discretion, to be satisfactory.

      (d) The Company and MMIC jointly and severally agree to pay to Escrow
Agent compensation for its services hereunder in accordance with the schedule of
fees set forth on Exhibit A attached hereto. In the event Escrow Agent renders
any extraordinary services in connection with the Escrow Account, Escrow Agent
shall be entitled to additional compensation therefore provided both the Company
and Sandler have requested the services and Escrow Agent has informed the
Company, in writing, of

                                       5
<PAGE>
the additional charge. Each of the Escrow Agent and the other Indemnitees, as
provided in (e) below, shall have a first lien against the Company's rights in
and to the funds in the Escrow Account to secure the respective obligations of
the Company to it hereunder. The terms of this paragraph shall survive
termination of this Agreement.

      (e) The Company and MMIC hereby agree to jointly and severally indemnify
Escrow Agent and its officers, agents, employees and directors (collectively,
the "Indemnitees") and hold the Indemnitees harmless from any and against all
liabilities, losses, actions, suits or proceedings at law or in equity, and any
other expenses, fees or charges of any character or nature, including, without
limitation, attorney's fees and expenses, which the Indemnitees may incur or
with which any Indemnitee may be threatened by reason of Escrow Agent acting as
escrow agent under this Agreement or arising out of the existence of the Escrow
Account, except to the extent the same shall be caused by any Indemnitee's gross
negligence or willful misconduct. The Indemnitees shall have a first lien
against the Company's rights in and to the funds in the Escrow Account to secure
the obligations of the Company hereunder. The terms of this paragraph shall
survive termination of this Agreement.

      (f) Whenever Escrow Agent is unable to decide between alternative courses
of action permitted or required by the terms of this Agreement, is unsure as to
the application, intent, interpretation or meaning of any provision of this
Agreement, or otherwise determines instruction to be necessary or desirable,
Escrow Agent shall promptly give notice (in such form as shall be reasonable
under the circumstances) to the Company requesting instruction as to the course
of action to be adopted, and, to the extent Escrow Agent acts in good faith in
accordance with any such instruction received, Escrow Agent shall not be liable
on account of such action to any person. In the event Escrow Agent receives
conflicting instructions under this Agreement, Escrow Agent shall be fully
protected in refraining from acting until such conflict is resolved to the
reasonable satisfaction of Escrow Agent.

      (g) Escrow Agent shall be entitled to consult with legal counsel in the
event that a question or dispute arises with regard to the construction of any
of the provisions hereof, and shall incur no liability and shall be fully
protected in acting in accordance with the advice or opinion of such counsel,
unless such advice or opinion constitutes gross negligence or willful misconduct
on the part of such counsel. In addition, Escrow Agent may perform its duties
hereunder either directly or by or through agents, accountants or attorneys and
shall not be responsible for any misconduct or negligence on the part of any
agent, accountant or attorney appointed with due care by it except for willful
misconduct and gross negligence; nor shall Escrow Agent be liable for any error
of judgment made in good faith by any of its officers or employees unless such
error constitutes gross negligence or willful misconduct.

      (h) The Escrow Agent represents and warrants to the Company that the
Escrow Agent is a "bank," as such term is defined in Section 3(a)(6) of the
Securities and Exchange Act of 1934, as amended.

      (i) Escrow Agent may resign as Escrow Agent by giving notice in writing of
such resignation to the Company, which notice shall specify a date upon which

                                       6
<PAGE>
such resignation shall take effect. The Company shall, within sixty (60)
business days after receiving the foregoing notice from Escrow Agent, designate
a substitute escrow agent (the "Substitute Escrow Agent"), which Substitute
Escrow Agent shall, upon its designation and notice of such designation to
Escrow Agent, succeed to all of the rights, duties and obligations of Escrow
Agent hereunder. The Escrow Agent's resignation shall not be effective until the
Substitute Escrow Agent has been designated. In the event the Company shall not
have delivered to Escrow Agent a written designation of Substitute Escrow Agent
within the aforementioned sixty (60) day period, together with the consent to
such designation by the Substitute Escrow Agent, the Escrow Agent may apply to a
court of competent jurisdiction to appoint a Substitute Escrow Agent, and the
costs of obtaining such appointment shall be reimbursable from the Company and
from the Escrow Amount. Upon the Escrow Agent's effective resignation, the
Escrow Agent shall be discharged from any and all further duties and obligations
under this Agreement.

XII. NOTICES.

      Except as otherwise provided herein, any notice, instruction, instrument
or other document to be delivered hereunder shall be in writing and shall be

or at such other address specified in writing by the addressee, or upon actual
receipt via facsimile or telecopier transmission at the number set forth on the
signature page hereof or at such other number specified in writing by the
addressee.

XIII. AMENDMENT.

altered except by an instrument in writing signed by the parties hereto.

XIV. TERMINATION.

      This Agreement will terminate upon the disbursement of all funds in the
Escrow Account, as provided above, by the Escrow Agent.

XV. GOVERNING LAW.

      This Agreement shall be governed by and construed in accordance with
Delaware law in all respects (without regard to principles of conflict of laws).
Each of the Company, MMIC and the Escrow Agent hereby consent to (i) the
non-exclusive jurisdiction of the courts of the State of Delaware and (ii)
service of process by mail in accordance with Section XII.

XVI. COUNTERPARTS.

      This Agreement may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, and such counterparts
together shall constitute and be one and the same instrument.

or covered by an opinion of, any specified Person, it is not necessary that all

or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations

            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 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 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
<PAGE>
                                       14

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

            (c) The principal amount and serial numbers of Registered Securities
held by any Person, and the date of holding the same, shall be proved by the
Security Register.

            (d) The principal amount and serial numbers of Bearer Securities
held by any Person, and the date of holding the same, 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 principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner that the Trustee deems
sufficient.

            (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, by or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or 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,
<PAGE>
                                       15

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 eleven months 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 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 documents 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 Division, or

            (2) the Company by the Trustee or by any Holder shall be sufficient
      for every purpose hereunder (unless otherwise herein expressly provided)
      if in writing and mailed, first-class postage prepaid, to the Company,
      Attention: Vice President, Secretary and General Counsel 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.

            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, to each such Holder affected by such
event, at his address as it appears in the Security Register, not later than the
latest date, and not earlier than the earliest 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. 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.
<PAGE>
                                       16

            In case, by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impractical to mail
notice of any event to Holders of Registered Securities when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be sufficient giving of such notice 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 to Holders of Bearer Securities if published in 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 at least twice, the first
such publication to be not earlier than the earliest date, and not later than
the latest date, prescribed for the giving of such notice. Any such notice shall
be deemed to have been given on the date of the first such publication.

            In case, 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 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.
<PAGE>
                                       17

            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
Authenticating Agent, any Paying Agent, any Securities Registrar and their
successors hereunder and the Holders of Securities or coupons, 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. 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,
sinking fund payment date or 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 of 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 or Redemption
Date or sinking fund payment date, or at the Stated Maturity or Maturity;
provided that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity, as the case may be.

                                       18

            SECTION 113. Currency Indemnity Any amount received or recovered in
respect of Securities issued under this Indenture in a currency (the "Judgment
Currency") other than the currency other than the currency by which such series
of Securities is denominated (the "Required Currency") (whether as a result of,
or of the enforcement of, a judgment or order of a court of any jurisdiction, in
the winding up or dissolution of the Company, any Subsidiary of the Company or
otherwise) by a Holder in respect of any sum expressed to be due to such Holder
from the Company shall constitute a discharge of the Company's obligations only
to the extent of the Required Currency amount which the recipient is able to
purchase with the amount so received or recovered in such other currency on the
date of that receipt or recovery (or, if it is not possible to purchase the
Required Currency on that date, on the first date on which it is possible to do
so). If the Required Currency amount to be recovered is less than the Required
Currency amount expressed to be due to the recipient under any Securities, the
Company agrees to indemnify the recipient against the cost of making such
purchase, the cost of such purchases in each case being determined by reference
to the spot rate of exchange in New York, New York at which any such person on
the date of such receipt or recovery is able to purchase the Required Currency
with the Judgment Currency. The foregoing indemnities, to the extent permitted
by law: (a) constitute a separate and independent obligation from the other
obligations of the Company; (b) shall give rise to a separate and independent
cause of action; (c) shall apply irrespective of any waiver granted by any
Holder; and (d) shall continue in full force and effect despite any other
judgment, order, claim or proof for a liquidated amount in respect of any sum
due under any Securities or other judgment or order. The term "spot rate of
exchange" shall include any premiums and costs of exchange payable in connection
with the purchase of, or conversion into, the Required Currency.

            SECTION 114. Conflict with Trust Indenture Act.

            If and to the extent that any provision hereof limits, qualifies or
conflicts with the duties imposed by any of Sections 310 to 318, inclusive, of
the Trust Indenture Act, through operation of Section 318(c) thereof, such
imposed duties shall control.

            SECTION 115. Incorporators, Shareholders, Officers and Directors of
the Company Exempt from Individual Liability.

            No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any incorporator, as such, or against
any past, present or future shareholder, officer or director, as such, of the
Company or of any successor, either directly or through the Company or any
successor, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the Holders and as part of the consideration for
the issue of the Securities.

other marks of identification and such legends or endorsements placed thereon as
may be required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities
or coupons, as evidenced by their execution of the Securities or coupons. If the
forms of Securities or coupons of any series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 303 for the authentication and delivery of such
Securities or coupons. Any portion of the text of any Security may be set forth
on the reverse thereof, with an appropriate reference thereto on the face of the
Security.

            Unless otherwise specified as contemplated by Section 301,
Securities in bearer form shall have interest coupons attached.

            The Trustee's certificate of authentication on all Securities shall
be in substantially the form set forth in this Article.

of one or more temporary global Securities, in fully registered form without
interest coupons, with such applicable legends as are provided for in Section

custodian for the Depositary, duly executed by the Company and authenticated by
the Trustee as hereinafter provided, for credit to the respective accounts at
the Depositary of the depositories for Euroclear and for Clearstream, for credit
to the respective accounts of owners of beneficial interests in such Securities
or to such other accounts as they may direct. Until such time as the Restricted
Period in respect of securities of a series shall have terminated, such
temporary global Securities shall be referred to herein as "Temporary Regulation
S Global Securities". On or after the termination of the Restricted Period,
interests in any Temporary Regulation S Global Security of a series shall be
exchangeable for corresponding interests in an unrestricted Regulation S Global
Security of the same series (each a "Regulation S Global Security") in fully
registered form without interest coupons, with such applicable legends as are
provided for in Section 204 and in accordance with the immediately following
paragraph.

            (ii) Interests in a Temporary Regulation S Global Security of a
      series may be exchanged for interests in a Regulation S Global Security of
      the same series representing the same underlying indebtedness only on or

                              credited to a specified Agent Member's account a
                              beneficial interest in the Regulation S Global
                              Security in an Amount Payable at Maturity equal to

                              Agent Member's account is held, to be credited

                  (D) receipt by the Trustee of notification from the Depositary
            of the transactions described in (C) above,

the Trustee, as Security Registrar, shall instruct the Depositary to reduce the
Amount Payable at Maturity of the Temporary Regulation S Global Security and to
increase the Amount Payable at Maturity of the Regulation S Global Security, by
the Amount Payable at Maturity of the beneficial interest in such Temporary
Regulation S Global Security to be so transferred, and to credit or cause to be
credited to the account of the Person specified in such instructions a
beneficial interest in the Regulation S Global Security having an Amount Payable
at Maturity equal to the amount by which the Amount Payable at Maturity of the
Temporary Regulation S Global Security was reduced upon such transfer. The

the Depositary, in connection with a corresponding decrease or increase in the

      interest upon transfer shall be made through a Restricted Global Security
      in accordance with the certification requirements discussed below in

deposited with the Trustee, as custodian for the Depositary, duly executed by
the Company and authenticated by the Trustee as hereinafter provided for credit
to the respective accounts of owners of beneficial interests in such Securities
or to such other accounts as they may direct. The aggregate principal amount of
a Restricted Global Security of a series may be increased or decreased from time
to time by adjustments made on the records of the Trustee, as custodian for the
Depositary, in connection with a corresponding decrease or increase in the
aggregate principal amount, as hereinafter provided.

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

form shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

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 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 Securities.

            Unless otherwise specified as contemplated by Section 301 for 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. Not all Securities of any one series need be issued at the same time,
and, unless otherwise provided, a series may be reopened for issuances of
additional Securities of such series.

            If any of the terms of the series are established by action taken
pursuant to one or more Board Resolutions, such Board Resolutions shall be
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

            SECTION 302. Denominations.

            The Securities of each series shall be issuable in such
denominations as shall be specified as contemplated by Section 301. With respect
to Securities of any series denominated in Dollars, in the absence of any such
provisions, 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 the 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 two persons, including one of the Chief
Executive Officer, Chief Operating Officer or Chief Financial Officer of the
Company and any President or Vice President of the Company. The signature of any
of these officers on the Securities or coupons may be the 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
<PAGE>
                                       29

accordance with such Company Order shall authenticate and deliver such
Securities; 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, 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 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 not all the Securities of any series are 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 terms of particular
Securities of such series such as interest rate, stated maturity, 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, 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;

            (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 the 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;

            (d) that all laws and requirements in respect of the execution and
      delivery by the Company of such Securities, any coupons and of the
      supplemental indenture, if any,
<PAGE>
                                       30

      have been complied with and that authentication and delivery of such
      Securities and any coupons and the execution and delivery of the
      supplemental indenture, if any, by the Trustee will not violate the terms
      of the Indenture;

            (e) that the Company has the corporate power to issue such
      Securities and any coupons, and has duly taken all necessary corporate
      action with respect to such issuance; and

            (f) that the issuance of such Securities and any coupons will not
      contravene the articles of incorporation or by-laws of the Company or
      result in any violation of any of the terms or provisions of any law or
      regulation or of any indenture, mortgage or other agreement known to such
      Counsel by which the Company is bound.

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

            The Trustee shall not be required to authenticate and deliver any
such Securities if the issue of such Securities pursuant to this Indenture will
affect the Trustee's own rights, duties or immunities under the Securities and
this Indenture or otherwise in a manner which is not reasonably acceptable to
the Trustee.

            Each 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 a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
officer, 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.

            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
<PAGE>
                                       31

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 conclusively the officers
executing such Securities may determine, as conclusively evidenced by their
execution of such Securities. 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 the provisions of the following
paragraphs), if temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series (accompanied by any unmatured coupons
appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations; 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.

            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, England 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, 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
<PAGE>
                                       32

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-3 to this
Indenture (or in such other form as may be established pursuant to Section 301);
and provided further that 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 in the event that
such Person does not take 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-3 to this Indenture (or in such other form as may be
established pursuant to Section 301), for credit without further interest
thereon on or after such Interest Payment Date to the respective accounts of the
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 in Exhibit A-1 to this Indenture (or in such other form 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 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
<PAGE>
                                       33

unless and until such interest in such temporary Global Security shall have been
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 immediately prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company in accordance with Section
1003.

            SECTION 305. Registration, Registration of Transfer and Exchange.

            The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register for each series of Securities (the registers maintained
in the Corporate Trust Office of the Trustee and in any other office or agency
of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of 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. At all reasonable times, the
Security Register shall be open to inspection by the Trustee. The Trustee is
hereby initially appointed as security registrar (the "Security Registrar") for
the purpose of registering Registered Securities and transfers of Registered
Securities as herein provided. The Company shall have the right to remove and
replace from time to time the Security Registrar for any services of Securities;
provided that, no such removal or replacement shall be effective until a
successor Security Registrar with respect to such series of Registered
Securities shall have been appointed by the Company and shall have accepted such
appointment by the Company. In the event that the Trustee shall not be or shall
cease to be the Security Registrar with respect to a series of Securities, it
shall have the right to examine the Security Register for such series at all
reasonable times. There shall be only one Security Register for such series of
Securities.

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

            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 and of a like aggregate principal amount, upon surrender
of the Registered Securities to be exchanged at such office or agency. Whenever
any Registered Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Registered
Securities which the Holder making the exchange is entitled to receive. Unless
otherwise specified 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) expressly permitted in or pursuant to 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 denomination and of a like aggregate principal amount
and tenor, upon
<PAGE>
                                       34

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 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
<PAGE>
                                       35

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 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.

            If at any time the Depositary for Securities of a series notifies
the Company that it is unwilling, unable or no longer qualifies to continue as
Depositary for Securities of such series or if at any time the Depositary for
Securities for such series shall no longer be registered or in good standing
under the Exchange Act, if required to be so registered, or other applicable
statute or regulation, the Company shall appoint a successor depositary with
respect to the Company within 90 days after the Company receives such notice or
becomes aware of such condition, as the case may be, the Company's election
pursuant to Section 301 shall no longer be effective with respect to the
Securities for such series and the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of definitive
Securities of such series, will authenticate and deliver Securities of such
series in definitive registered form, in authorized denominations, and in an
aggregate principal amount equal to the principal form, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security or Securities representing such series in exchange
for such Global Security or Securities.

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

            Upon the exchange of a Global Security for Securities in definitive
registered form, such Global Security shall be cancelled by the Trustee.
Securities issued in exchange for a Global Security pursuant to this Section
shall be registered in such names and in such authorized
<PAGE>
                                       36

denominations as the depositary for such Global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee in writing. The Trustee shall deliver such Securities to
the persons in whose names such Securities are so registered.

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

            Every 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 Securities of any series during a period beginning at
the opening of business 15 days before the day of the selection for redemption
of Securities of that series under Section 1103 or 1203 and ending at the close
of business on (A) if Securities of the series are issuable only as Registered
Securities, the day of the mailing of the relevant notice of redemption and (B)
if Securities of the series are issuable as Bearer Securities, the day of the
first publication of the relevant notice of redemption or, if Securities of the
series 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 the unredeemed portion of any Security being redeemed
in part, or (iii) to exchange any Bearer Security so selected for redemption
except that such a Bearer Security may be exchanged for a Registered Security of
that series and like tenor; provided that such Registered Security shall be
immediately 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.

            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, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding, with coupons corresponding to the coupons, if
any, appertaining to the surrendered Security, or, in case any such mutilated
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 the surrendered Security,
pay such Security or coupon.

<PAGE>

                                       37

         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 protected purchaser (as defined in Article 8 of the UCC), the
Company shall execute and upon Company Order the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security or in exchange
for the Security for 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 of like tenor and principal amount 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.

         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 with its coupons, if any, issued
pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security or in exchange for a Security to which a mutilated, destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the mutilated, destroyed, lost or
stolen Security and its coupons, if any, or the mutilated, 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, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally 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.
<PAGE>
                                       38

         (a)      Unless otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest, if any, on any Registered
Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such 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 the principal of (and premium, if any) and 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) wire transfer to an account of
the person entitled to receive such payment if such person is a Holder of
$10,000,000 or more in aggregate principal amount of the Securities of such
series (with wire transfer instruction provided to the Trustee not less than 15
days prior to payment of interest by wire transfer); provided further, that
principal paid in relation to any Security redeemed at the option of the Company
pursuant to Article Eleven, or paid at Maturity, shall be paid to the holder of
such Security only upon presentation and surrender of such Security to such
office or agency referred to in this Section 307(a).

         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 Bearer Security, by transfer to an account located outside the
United States maintained by the payee.

         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.

         Any interest on any Registered Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date
shall forthwith cease to be payable to the Holder on the relevant Regular Record
Date by virtue of having been such Holder, and such defaulted interest and, if
applicable, interest on such defaulted interest (to the extent lawful) at the
rate specified in the Securities of such series (such defaulted interest and, if
applicable, interest thereon herein collectively called "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, 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
<PAGE>
                                       39

    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 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 given in the manner provided in
    Section 106, not less than 10 days prior to such Special Record Date. Notice
    of the proposed payment of such Defaulted Interest and the Special Record
    Date therefor having been so given, such Defaulted Interest shall be paid to
    the Persons in whose name 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).

         (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 50 but not more
than 60 days prior to an Optional Reset Date for such Note. 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 the Stated
Maturity Date 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 an interest rate (or
a spread or spread multiplier used to calculate such interest rate, if
applicable) that is higher than the interest rate (or the spread or spread
multiplier, if applicable) provided for in the Reset Notice, for the Subsequent
Interest Period by causing the Trustee to transmit, in the
<PAGE>
                                       40

manner provided for in Section 106, notice of such higher interest rate (or such
higher spread or spread multiplier, 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
higher spread or spread multiplier, if applicable).

         The Holder of any such Security will 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 Stated 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 50
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 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, 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 provided for in the Extension Notice and establish a
higher interest rate for the Extension Period by causing the Trustee to
transmit, in the manner provided for in Section 106, notice of such higher
interest
<PAGE>
                                       41

rate 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 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 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 Registered 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 Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Company, the Trustee or
any agent of the Company or the Trustee shall be affected by notice to the
contrary.

         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
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 coupons be overdue, and none of the Company, the
Trustee or any agent of the Company or the Trustee shall be affected by notice
to the contrary.

         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.
<PAGE>
                                       42

         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 current or future sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee.
All Securities and coupons so delivered to the Trustee 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. All cancelled
Securities held by the Trustee shall be disposed of by the Trustee in accordance
with its customary procedures and certification of their disposal delivered to
the Company unless by Company Order the Company shall direct that cancelled
Securities be returned to it.

         SECTION 311. Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 with
respect to any Securities, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months. For
the purposes of disclosure under the Interest Act (Canada), the yearly rate of
interest to which interest calculated under a Security for any period in any
calendar year (the "calculation period") is equivalent, is the rate payable
under a Security in respect of the calculation period multiplied by a fraction
the numerator of which is the actual number of days in such calendar year and
the denominator of which is the actual number of days in the calculation period.

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

         (a)      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 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
<PAGE>
                                       43

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 (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 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 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, in 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 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 of such series 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 Officers' Certificate in respect of the Dollar or Foreign
Currency payments to be made on such payment date. Unless otherwise specified
pursuant to Section 301, the Dollar or Foreign Currency 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 third 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 and by
the 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
<PAGE>
                                       44

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) above.

         (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.

         (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 value 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
<PAGE>
                                       45

    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 date for any series of Registered
    Securities as specified pursuant to clause (13) of Section 301 by which the
    written election referred to in paragraph (b) above may be made.

         All decisions and determinations of the Exchange Rate Agent regarding
the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the
Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as
specified above shall be in its sole discretion and shall, in the absence of
manifest error, be conclusive for all purposes and irrevocably binding upon the
Company, the Trustee and 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 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 and to the Exchange
Rate Agent (and the Trustee will promptly thereafter give notice in the manner
provided for 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 and to the Exchange Rate Agent (and the Trustee will
promptly thereafter give notice in the manner provided for 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 and the Exchange Rate Agent.

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

         SECTION 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 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 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
<PAGE>
                                       46

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 Currency into the applicable payment Currency for the payment of
principal (and premium, if any) and interest, if any, pursuant to Section 312.

         (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.

         (c)      The Company shall have the right to remove and replace from
time to time the Exchange Rate Agent for any series of Securities. 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 shall promptly notify the Trustee of any
change in "CUSIP" numbers.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

         SECTION 401. Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Request cease to be of further effect
with respect to any series of Securities specified in such Company Request

Securities of such series expressly provided for herein or pursuant hereto) and
the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture as to such series

         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 with the
         Trustee or any Paying Agent or segregated and held in trust by the
         Company and thereafter repaid to the Company, 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

                           (i)      have become due and payable, or

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

                           (iii)    if redeemable at the option of the 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 not theretofore
         delivered to the Trustee for cancellation, for 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
obligations of the Company to the Trustee under Section 606, the obligations of
the Trustee to any Authenticating Agent under Section 611 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee
<PAGE>
                                       48

under Section 402 and the last paragraph of Section 1003 shall survive such
satisfaction and discharge.

         SECTION 402. Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, 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 the Trustee; but such money need not be segregated from other
funds except to the extent required by law.

                                  ARTICLE FIVE

                                    REMEDIES

    breach for a period of 90 days after there has been given, by registered or
    certified mail, to the Company by the Trustee or to the Company and the
    Trustee by the Holders of at least 25% in principal amount of all
    Outstanding Securities of any series affected thereby a written notice

    in the premises adjudging the Company a bankrupt or insolvent, or approving

    federal, provincial, state or foreign bankruptcy, insolvency or analogous
    laws, or the issuance of a sequestration order or the appointment of a
    receiver, liquidator, assignee, trustee, sequestrator (or other similar
    official) of the Company or in receipt of any substantial part of the
    property of the Company, and any such decree, order or appointment continues
    unstayed and in effect for a period of 90 consecutive days; or

         (6)      the institution by the Company of proceedings to be
    adjudicated a bankrupt or insolvent, or the consent by it to the institution

    assignment for the benefit of creditors, or the admission by it in writing
    of its inability to pay its debts generally as they become due or the taking
    by it of corporate action in furtherance of any of the aforesaid purposes;
    or

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

         SECTION 502. Acceleration of Maturity; Rescission and Annulment.

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

         At any time after a declaration of acceleration with respect to
Securities of any series (or of all series, as the case may be) 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 (or of
all series, as the case may be), by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if
<PAGE>
                                       50

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

                  (A)      all overdue interest, if any, on all Outstanding
         Securities of that series (or of all series, as the case may be) and
         any related coupons,

                  (B)      all unpaid principal of (and premium, if any) any
         Outstanding Securities of that series (or of all series, as the case
         may be) which has become due otherwise than by such declaration of
         acceleration, and interest on such unpaid principal at the rate or
         rates prescribed therefor in such Securities,

                  (C)      to the extent that payment of such interest is
         lawful, interest on overdue interest, if any, at the rate or rates
         prescribed therefor in such Securities, and

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

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

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

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

         The Company covenants that if

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

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

then the Company will, upon demand of the Trustee, pay to the Trustee for the
benefit of the Holders of such Securities and coupons, the whole amount then due
and payable on such Securities and coupons for principal (and premium, if any)
and interest, if any, and interest on any overdue principal (and premium, if
any) and on any overdue interest, at the rate or rates prescribed therefor in
such Securities, and, in addition thereto, such 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.
<PAGE>
                                       51

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

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

         SECTION 504. Trustee May File Proofs of Claim.

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

         (i)      to file a proof of claim for the whole amount of principal
    (and premium, if any), or such portion of the principal amount of any series
    of Original Issue Discount Securities or Indexed Securities as may be
    specified in the terms of such series, 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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the 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 any plan of
reorganization, arrangement,
<PAGE>
                                       52

adjustment or composition affecting the Securities or the rights of any Holder
thereof or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

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

         All rights of action and claims under this Indenture or the Securities
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 under Section 606;

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

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

         SECTION 507. Limitation on Suits.

         No Holder of any Security of any series or any related coupons 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 satisfactory to it against the costs, expenses and liabilities to
    be incurred in compliance with such request;
<PAGE>
                                       53

         (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 Holders.

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

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment, as provided herein (including, if applicable, Article Fourteen)
and in such Security, of the principal of (and premium, if any) and (subject to
Section 307) interest, if any, on, such Security or payment of such coupon on
the respective Stated Maturities 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 has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders of
Securities and coupons shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.

         SECTION 510. Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities 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.
<PAGE>
                                       54

         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, as
the case may be.

         SECTION 512. Control by Holders.

         With respect to the Securities of any series, the Holders of not less
than a majority in principal amount of the Outstanding Securities of such 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, relating to or arising under Section 501,
provided that:

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

         (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. Waiver of Past Defaults.

         Subject to Section 502, 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 waive any past default
described in Section 501, and its consequences, except a default

         (1) in respect of the payment of the principal of (or premium, if any)
    or interest, if any, on any Security or any related coupon, 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, any 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 514. Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or
<PAGE>
                                       55

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

                                   ARTICLE SIX

                                   THE TRUSTEE

         SECTION 601. Notice of Defaults.

         Within 90 days after the occurrence of any Default hereunder with
respect to the Securities of any series, the Trustee shall transmit 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 fund installment with respect to
Securities of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the interest of the
Holders of Securities of such series and any related coupons; and provided
further that in the case of any Default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof.

         SECTION 602. Certain Rights of Trustee.

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

    instrument, opinion, report, notice, request, direction, consent, order,
    bond, debenture, note, other evidence of indebtedness or other paper or
    document believed by it to be genuine and to have been signed or presented
    by the proper party or parties;

         (2) any request or direction of the Company mentioned herein shall be
    sufficiently evidenced by a Company Request or Company Order and any
    resolution of the Board of Directors may be sufficiently evidenced by a
    Board Resolution;

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

         (4) the Trustee may consult with counsel and the advice of such counsel
    or any Opinion of Counsel shall be full and complete authorization and
    protection in respect
<PAGE>
                                       56

    of any action taken, suffered or omitted by it hereunder in good faith and
    in reliance thereon;

         (5) 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 reasonable security or indemnity satisfactory to it against the
    costs, expenses and liabilities which might be incurred by it in compliance
    with such request or direction;

         (6) the Trustee shall not be bound to make any investigation into the
    facts or matters stated in any resolution, certificate, statement,
    instrument, opinion, report, notice, request, direction, consent, order,
    bond, debenture, note, other evidence of indebtedness or other paper or
    document, but the Trustee, in its discretion, may make such further inquiry
    or investigation into such facts or matters as it may see fit, and, if the
    Trustee shall determine to make such further inquiry or investigation, it
    shall be entitled to examine the books, records and premises of the Company,
    personally or by agent or attorney at the expense of the Company and shall
    incur no liability of any kind by reason of such inquiry or investigation;

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

         (8) the Trustee shall not be 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.

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

         The 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.

         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 case of its
capacities hereunder, and each agent, custodian and other Person employed to act
hereunder.

         SECTION 603. Trustee Not Responsible for Recitals or Issuance of
Securities.

<PAGE>
                                       57

            The recitals contained herein and in the Securities, except for the
Trustee's certificates 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 Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company or of the Trustee, 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,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

            SECTION 605. Money Held in Trust.

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

            SECTION 606. Compensation and Reimbursement.

            The Company agrees:

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

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

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

            The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and
<PAGE>
                                       58

hold harmless the Trustee shall constitute additional indebtedness hereunder and
shall survive the satisfaction and discharge of this Indenture. As security for
the performance of such obligations of the Company, 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 in connection
with an Event of Default specified in Section 501(5) or (6), the expenses
(including reasonable charges and expense of its counsel) of and the
compensation for such services are intended to constitute expenses of
administration under any applicable U.S. or Canadian federal, state or
provincial bankruptcy, insolvency or other similar law.

            The provisions of this Section shall survive the termination of this
Indenture and the resignation or removal of the Trustee.

            SECTION 607. Corporate Trustee Required; Eligibility.

            (a)   There shall be at all times 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 to the requirements
of Federal, State, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

            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. If the instrument of acceptance by a successor Trustee required by
Section 609 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition at
the expense of the Company any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

            (c)   The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and to the Company. If the instrument of acceptance by a successor
Trustee required by Section 609 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition at the expense of the Company any court of competent
<PAGE>
                                       59

jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

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

            (e)   If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series). 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 and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Security of such series for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

            (f)   The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to the Holders of Securities of such series in
<PAGE>
                                       60

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

            (b)   In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the 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. Whenever there is a successor Trustee with
respect to one or more (but less than all) series of securities issued pursuant
to this Indenture, the terms "Indenture" and "Securities" shall have the
meanings specified in the provisos to the respective definitions of those terms
in Section 101 which contemplate such situation.

            (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
<PAGE>
                                       61

Trustee all 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 the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities. In case
any of the Securities shall not have been authenticated by such predecessor
Trustee, any successor Trustee may authenticate such Securities either in the
name of any predecessor hereunder or in the name of the successor Trustee. In
all such cases such certificates shall have the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or to authenticate Securities in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

            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 and the Trustee shall give
written notice of such appointment to all Holders of Securities of the series
with respect to which such Authenticating Agent will serve, in the manner
provided for in Section 106. 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, and a copy of such instrument shall be promptly furnished to the
Company. Wherever reference is made in this Indenture to the authentication and
delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States, any state thereof or the District of Columbia, authorized under such
laws to act as Authenticating Agent, having a combined capital and surplus of
not less than $50,000,000 and subject to supervision or examination by federal
or state authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the
<PAGE>
                                       62

purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, it
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 any further
act on the part of the Trustee or the Authenticating Agent.

            An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give written notice of
such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for 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. 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 for its services under this Section.

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

            Dated: ____________________

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

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

            SECTION 701. Disclosure of Names and Addresses of Holders.

            Every Holder of Securities or coupons, by receiving and holding the
same, agrees with the Company and the Trustee that none of the Company or the
Trustee or any agent of either of them shall be held accountable by reason of
the disclosure of any such information as to the names and addresses of the
Holders in accordance with TIA Section 312, regardless of the source from which
such information was derived, and that the Trustee shall not be held accountable
by reason of mailing any material pursuant to a request made under TIA Section
312(b).

            SECTION 702. Reports by Trustee.

            (a) Within 60 days after May 15 of each year commencing with the
      first May 15 after the first issuance of Securities pursuant to this
      Indenture, the Trustee shall transmit to the Holders of Securities, in the
      manner and to the extent provided in Section 313(c) of the Trust Indenture
      Act, a brief report dated as of such May 15 if required by Section 313(a)
      of the Trust Indenture Act.

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

            (c) A copy of such report shall, at the time of such transmission to
      the Holders, be filed by the Trustee with the Company (Attention: Vice
      President and General Counsel), with each securities exchange upon which
      any of the Securities are listed (if so listed) and also with the
      Commission. The Company agrees to notify the Trustee when the Securities
      become listed on any stock exchange.

            SECTION 703. Reports by Company.

            The Company shall:

            (1)   file with the Trustee, within 15 days after the Company is
      required to file the same with the Commission, copies of the annual
      reports and of the information, documents and other reports (or copies of
      such portions of any of the foregoing as the Commission may from time to
      time by rules and regulations prescribe) which the Company may be required
      to file with the Commission pursuant to Section 13 or Section 15(d) of the
      Securities Exchange Act of 1934; or, if the Company is not required to
      file information, documents or reports pursuant to either of such
      Sections, then it shall file with the Trustee and the Commission, in
      accordance with rules and regulations prescribed from time to time by the
      Commission, such of the supplementary and periodic information, documents
      and reports which may be required pursuant to Section 13 of the Securities
      Exchange Act of 1934 in respect of a security listed and registered on a

<PAGE>
                                       67

            (1)   change the Stated Maturity of the principal of (or premium, if
      any) or any installment of interest on any Security of such series, or
      reduce the principal amount thereof (or premium, if any) or the rate of
      interest, if any, thereon (except as contemplated by Section 801(1) and
      permitted by Section 901(1)), or reduce the amount of the principal of an
      Original Issue Discount Security of such series 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 any Holder of any Security of such series, or change any Place
      of Payment where, or the Currency in which, any Security of such series or

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

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

                                       68

Opinion of Counsel stating that the execution of such supplemental indenture is

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

            SECTION 1002. Maintenance of Office or Agency.

            If the Securities of a series are issuable only as Registered
Securities, the Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, 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 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 payment;
provided, however, that, if the Securities of that series are listed on any
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 any required city located outside the United States 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 and 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 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 any series and the
related coupons may be presented and surrendered for payment at the offices
specified in the Security, in London, and the Company hereby appoints the same
as its agents to receive such respective 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
<PAGE>
                                       70

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 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 also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
any such designation; 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 as contemplated by 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,
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 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 (or premium, if any) or 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, prior to or on 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.
<PAGE>
                                       71

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

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

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

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

            The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which 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 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, or any coupon appertaining thereto, and
remaining unclaimed for two years (or such shorter period as may be specified in
the applicable abandoned property statutes) after such principal, premium or
interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security or coupon shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in an Authorized Newspaper, 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. 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. For purposes of this Section 1004, such
<PAGE>
                                       72

compliance shall be determined without regard to any period of grace or
requirement of notice under this Indenture. Upon becoming aware of any Event of
Default, the Company will promptly notify the Trustee.

            SECTION 1005. Payment of Taxes and Other Claims.

            The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all material lawful claims for labor, materials and supplies which, if unpaid,
might by law become a Lien upon any Property of the Company or any Subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings.

            SECTION 1006. Corporate Existence.

            Subject to Article Eight, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate
existence and the rights (charter and statutory) and franchises of the Company
and any Subsidiary; 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 desirable in the conduct of the business of
the Company and its Subsidiaries as a whole.

            SECTION 1007. Waiver of Certain Covenants. The Company may, with
respect to any series of Securities, omit in any particular instance to comply
with any term, provision or condition as specified pursuant to Section 301(15)
for Securities of such series, in any covenants of the Company added to Article
Ten pursuant to Section 301(14) or Section 301(15) in connection with Securities
of such series, if before the time for such compliance the Holders of at least a
majority in principal amount of all Outstanding Securities of any series, by Act
of such Holders, waive such compliance in such instance 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 to Holders of Securities of such series in respect of any such term,
provision or condition shall remain in full force and effect.

            SECTION 1008. Calculation of Original Issue Discount.

            If any Securities are Original Issue Discount Securities, then the
Company shall file with the Trustee promptly at the end of each calendar year
(i) a written notice specifying the amount of original issue discount (including
daily rates and accrual periods) accrued on Outstanding Securities as of the end
of such year and (ii) such other specified information relating to such original
issue discount as may then be relevant under the Internal Revenue Code of 1986,
as amended from time to time.

                                 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 the terms of such Securities 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, 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 of such Redemption Date and of
the principal amount of Securities of such series to be redeemed and shall
deliver to the Trustee such documentation and records as shall enable the
Trustee to select the Securities to be redeemed pursuant to Section 1103. 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 are to be redeemed,
the particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal of Securities of such series; provided,
however, that no such partial redemption shall reduce the portion of the
principal amount of a Security not redeemed to less than the minimum authorized
denomination for Securities of such series established pursuant to Section 301.

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

            For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any 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.

            SECTION 1104. Notice of Redemption.

            Except as otherwise specified as contemplated by Section 301, notice
of redemption shall be given in the manner provided for in Section 106 not less
than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed. Failure
<PAGE>
                                       74

to give notice in the manner provided in Section 106 to the Holder of any
Securities 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 Securities or portion thereof.

            All notices of redemption shall state:

            (1)   the Redemption Date,

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

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

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

            (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 such Redemption Date pursuant to Section 305 or
      otherwise, the last date, as determined by the Company, on which such
      exchanges may be made.
<PAGE>
                                       75

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

            SECTION 1105. Deposit of Redemption Price.

            Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money in 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 Redemption Price of, and accrued interest, if any, on, all
the Securities which are to be redeemed on that date.

            SECTION 1106. Securities Payable on Redemption Date.

            Notice of redemption having been given as aforesaid, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified 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 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
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 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
<PAGE>
                                       76

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 principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth
in such Security.

            SECTION 1107. Securities Redeemed in Part.

            Any 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 such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series, 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.

                                 ARTICLE TWELVE

                                 SINKING FUNDS

            SECTION 1201. Applicability of Article.

            Retirements of Securities of any series pursuant to any sinking fund
shall be made in accordance with the terms of such Securities and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

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

            Subject to Section 1203, in lieu of making all or any part of any
mandatory sinking fund payment with respect to any Securities of a series in
cash, the Company may at its option (1) deliver to the Trustee Outstanding
Securities of a series (other than any previously called for redemption)
theretofore purchased or otherwise acquired by the Company together in the case
of any Bearer Securities of such series with all unmatured coupons appertaining
thereto, and/or (2) receive credit for the principal amount of Securities of
such series which have been previously delivered to the Trustee by the Company
or for Securities of such series which have
<PAGE>
                                       77

been redeemed either at the election of the Company pursuant to the terms of
such Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Securities, in each case in satisfaction
of all or any part of any mandatory sinking fund payment with respect to the
Securities of the same series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided, however, that
such Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such 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
any series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash 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 or crediting Securities of that series
pursuant to Section 1202 (which Securities will, if not previously delivered,
accompany such certificate) and whether the Company intends to exercise its
right to make a permitted optional sinking fund payment with respect to such
series. Such certificate shall be irrevocable and upon its delivery the Company
shall be obligated to make the cash payment or payments therein referred to, if
any, on or before the next succeeding sinking fund payment date. In the case of
the failure of the Company to deliver such certificate, the sinking fund payment
due on the next succeeding sinking fund payment date for that series shall be
paid entirely in cash and shall be sufficient to redeem the principal amount of
such Securities subject to a mandatory sinking fund payment without the option
to deliver or credit Securities as provided in Section 1202 and without the
right to make any optional sinking fund payment, if any, with respect to such
series.

            Not more than 60 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.

            Prior to any sinking fund payment date, the Company shall pay to the
Trustee or a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) in cash a sum equal to
any interest that will accrue to the date fixed for redemption of Securities or
portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section 1203.

            Notwithstanding the foregoing, with respect to a sinking fund for
any series of Securities, if at any time the amount of cash to be paid into such
sinking fund on the next succeeding sinking fund payment date, together with any
unused balance of any preceding
<PAGE>
                                       78

sinking fund payment or payments for such series, does not exceed in the
aggregate $100,000, the Trustee, unless requested by the Company, shall not give
the next succeeding notice of the redemption of Securities of such series
through the operation of the sinking fund. Any such unused balance of moneys
deposited in such sinking fund shall be added to the sinking fund payment for
such series to be made in cash on the next succeeding sinking fund payment date
or, at the request of the Company, shall be applied at any time or from time to
time to the purchase of Securities of such series, by public or private
purchase, in the open market or otherwise, at a purchase price for such
Securities (excluding accrued interest and brokerage commissions, for which the
Trustee or any Paying Agent will be reimbursed by the Company) not in excess of
the principal amount thereof.

                                ARTICLE THIRTEEN

                         REPAYMENT AT 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 as contemplated by Section
301 for Securities of any series) 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 a price equal to the principal amount 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 principal (or, if so provided by the terms of the Securities of any series,
a percentage of the principal) of and (except if the Repayment Date shall be an
Interest Payment Date) accrued interest, if any, 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 or which the Company shall from time to time notify the
Holders of such Securities) not earlier
<PAGE>
                                       79

than 45 days nor later than 30 days prior to the Repayment Date. If less than
the entire principal amount of such Security is to be repaid in accordance with
the terms of such Security, the principal amount 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 the principal amount of such Security surrendered that
is not to be repaid, must be specified. The principal amount of 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 principal amount 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, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment 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 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 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
<PAGE>
                                       80

otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

            If the principal amount of any Security surrendered for repayment
shall not be so repaid upon surrender thereof, such principal amount (together
with interest, if any, thereon accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in 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. Company's Option to Effect Defeasance or Covenant
Defeasance.

            Except as otherwise specified as contemplated by Section 301 for
Securities of any series, the provisions of this Article Fourteen shall apply to
each series of Securities, and the Company may, at its option, effect defeasance
of the Securities of or within a series under Section 1402, or covenant
defeasance of or within a series under Section 1403 in accordance with the terms
of such Securities and in accordance with 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 related coupons on the date the conditions set
forth in Section 1404 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 related coupons, 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 (A) and (B) below, and to have satisfied all its other
obligations under such Securities and any related coupons and this Indenture
insofar as such Securities and any related coupons 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 related coupons 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
<PAGE>
                                       81

Securities and any related coupons when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 304, 305, 306, 1002
and 1003, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article Fourteen. Subject to compliance with this Article
Fourteen, the Company may exercise its option under this Section 1402
notwithstanding the prior exercise of its option under Section 1403 with respect
to such Securities and any related coupons.

            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 803 and Sections 1005 through
1006 and, if specified pursuant to Section 301, its obligations under any other
covenant, with respect to such Outstanding Securities and any related coupons on
and after the date the conditions set forth in Section 1404 are satisfied
(hereinafter, "covenant defeasance"), and such Securities and any related
coupons shall thereafter be deemed not to be "Outstanding" for the purposes of
any direction, waiver, consent or declaration or Act of Holders (and the
consequences of any thereof) in connection with such covenants, 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 related coupons, 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 covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of reference in any
such 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 Section 501(7) or otherwise, as the case may be, but, except
as specified above, the remainder of this Indenture and such Securities and any
related coupons shall be unaffected thereby.

            SECTION 1404. Conditions to Defeasance or Covenant Defeasance.

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

            (1)   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 related coupons, (A) an amount (in such Currency in which such
      Securities and any related coupons are then specified as payable at Stated
      Maturity), or (B) Government Obligations applicable to such Securities
      (determined on the basis of the Currency in which such Securities 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,
      under such Securities and any related coupons, money in an amount, or (C)
      a combination thereof, sufficient, in the opinion of a nationally
      recognized firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay and discharge, and
      which shall be
<PAGE>
                                       82

      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 related coupons on the Stated Maturity (or
      Redemption Date, if applicable) of such principal (and premium, if any) or
      installment of interest, if any, and (ii) any mandatory sinking fund
      payments or analogous payments applicable to such Outstanding Securities
      and any related coupons 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 related coupons; provided that the Trustee shall have
      been irrevocably instructed to apply such money or the proceeds of such
      Government Obligations to said payments with respect to such Securities
      and any related coupons. Before such a deposit, the Company may give to
      the Trustee, in accordance with Section 1102 hereof, a notice of its
      election to redeem all or any portion of such Outstanding Securities at a
      future date in accordance with the terms of the Securities of such series
      and Article Eleven hereof, which notice shall be irrevocable. Such
      irrevocable redemption notice, if given, shall be given effect in applying
      the foregoing.

            (2)   No Default or Event of Default with respect to such Securities
      or any related coupons shall have occurred and be continuing on the date
      of such deposit or, insofar as paragraphs (5) and (6) of Section 501 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).

            (3)   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.

            (4)   In the case of an election under Section 1402, the Company
      shall have delivered to the Trustee an Opinion of Counsel in the United
      States stating that (x) the Company has received from, or there has been
      published by, the Internal Revenue Service a ruling, or (y) since the date
      of execution of this Indenture, there has been a change in the applicable
      U.S. 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 related coupons 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.

            (5)   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 related coupons
      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.

            (6)   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 in connection
      therewith pursuant to Section 301.
<PAGE>
                                       83

            (7)   The Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for relating to either the defeasance under Section
      1402 or the covenant defeasance under Section 1403 (as the case may be)
      have been complied with.

            (8)   Either the Company has delivered to the Trustee an Opinion of
      Counsel in Canada or a ruling from Canada Customs and Revenue Agency to
      the effect that the Holders of such Outstanding Securities will not
      recognize income, gain or loss for Canadian federal, provincial or
      territorial income tax or other tax purpose as a result of such defeasance
      or covenant defeasance and will be subject to Canadian federal or
      provincial income tax and other tax on the same amounts, in the same
      manner and at the same times as would have been the case had such
      defeasance not occurred (and for the purposes of such opinion, such
      Canadian counsel shall assume that Holders of the Securities include
      Holders who are not resident in Canada).

            (9)   The Company is not an "insolvent person" within the meaning of
      the Bankruptcy and Insolvency Act (Canada) on the date of such deposit or
      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).

            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 such Outstanding Securities
and any related coupons shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any related 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 Holders of such Securities and any related coupons 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.

            Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(1) 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(1) 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(1) has been made, the indebtedness represented by such Security and any
related coupons 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 they become 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
<PAGE>
                                       84

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 third
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 related
coupons.

            Anything in this Article Fourteen 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 an
equivalent defeasance or covenant defeasance, as applicable, in accordance with
this Article.

            SECTION 1406. Reinstatement.

            If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 1405 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and such
Securities and any related coupons shall be revived and reinstated as though no
deposit had occurred pursuant to Section 1402 or 1403, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1405; provided, however, that if the Company makes any
payment of principal of (or premium, if any) or interest, if any, on any such
Security or any related coupon following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities
and any related coupons to receive such payment from the money held by the
Trustee or Paying Agent.

                                ARTICLE FIFTEEN

                       MEETINGS OF HOLDERS OF SECURITIES

            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
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

<PAGE>
                                       85

            (a)   The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 1501, to be held
at such time and at such place in The City of New York or in London as the
Trustee shall determine. Notice of every meeting of Holders of Securities of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided for in Section 106, not less than 21 nor more than 180 days
prior to the date fixed for the meeting.

            (b)   In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1501, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount above specified, as the case may be, may determine the time and the
place in The City of New York or in London for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in paragraph (a)
of this Section.

            SECTION 1503. Persons Entitled to Vote at Meetings.

            To be entitled to vote at any meeting of Holders of Securities of
any series, a Person shall be (1) a Holder of one or more Outstanding Securities
of such series, or (2) a Person appointed by an instrument in writing as proxy

            SECTION 1504. Quorum; Action.

            The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that, if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of not less than a
specified percentage in principal amount of the Outstanding Securities of a
series, the Persons entitled to vote such specified percentage in principal
amount of the Outstanding Securities of such series shall constitute a quorum.
In the absence of a quorum within 30 minutes of the time appointed for any such
meeting, the meeting shall, if convened at the request of Holders of Securities
of such series, be dissolved. In any other case the meeting may be adjourned for
a period of not less than 10 days as determined by the chairman of the meeting
prior to the adjournment of such meeting. In the absence of a quorum at any such
adjourned meeting, such adjourned meeting may be further adjourned for a period
of not less than 10 days as determined by the chairman of the meeting prior to
the adjournment of such adjourned meeting. Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1502(a), except that

any
<PAGE>
                                       86

adjourned meeting shall state expressly the percentage, as provided above, of
the principal amount of the Outstanding Securities of such series which shall
constitute a quorum.

            Subject to the foregoing, at the reconvening of any meeting
adjourned for lack of a quorum the Persons entitled to vote 25% in principal
amount of the Outstanding Securities at the time shall constitute a quorum for
the taking of any action set forth in the notice of the original meeting.

            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
not less than a majority in principal amount of the Outstanding Securities of
such series; provided, however, that, except as limited by the proviso to
Section 902, any resolution with respect to any request, demand, 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 not less than such specified percentage in
principal amount of the Outstanding Securities of such 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:

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

            (ii)  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 Trustee
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
<PAGE>
                                       87

matters concerning the conduct of the meeting as its 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.

            (b)   The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, 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
Outstanding Securities of such series held or represented by him (determined as
specified in the definition of "Outstanding" in Section 101); 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 facts 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 latter to have attached thereto the
<PAGE>
                                       88

ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

            This Indenture may be executed in any number of counterparts, each
of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Indenture.
<PAGE>
                                       89

            IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed as of the day and year first above written.
