                              (a Colorado Company)

                   Warrant for the Purchase of [NUMBER] Shares
                                 of Common Stock
                            par value $.001 per share

Void after the earlier of (i) 5:00 p.m. Pittsburgh, Pennsylvania Time, on May
31, 2006 or (ii) that date which is sixty days after a call of this Warrant is
made in accordance with the provisions of Section 9 of this Warrant.

FOR VALUE RECEIVED, Demegen, Inc. (the "Company"), a Colorado Corporation,
hereby certifies that ___________________, or assigns ("Holder"), is entitled,
subject to the provisions of this Warrant, to purchase from the Company at any
time, or from time to time during the period commencing on the date hereof and
expiring on the "expiration date" as defined in Section 1 of this Warrant, up to
(_______) fully paid and non-assessable shares of Common Stock, at the rate of
one share of Common Stock for each Warrant so exercised, as may be adjusted in
accordance with the provisions of Section of this Warrant, at a price of $0.75
per share ("exercise price").

The term "Common Stock" means the common stock, par value $.001 per share, of
the Company as constituted on May 31, 2001 ("Base Date"), together with any
other equity securities that may be issued by the Company in respect thereof or
in substitution therefor. The number of shares of Common Stock to be received
upon the exercise of this Warrant may be adjusted from time to time as
hereinafter set forth.. The shares of Common Stock deliverable or delivered upon
such exercise, as adjusted from time to time, are hereinafter referred to as
"Warrant Stock."

Upon receipt by the Company of evidence reasonably satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant certificate, and (in the
case of loss, theft or destruction) of satisfactory indemnification, and upon
surrender and cancellation of this Warrant certificate, if mutilated, the
Company shall execute and deliver a new Warrant certificate of like tenor and
date.

Section 1. Exercise of Warrant. Subject to the call provision set forth in
Section 9, this Warrant may be exercised, subject to the requirements set forth
below, in whole, or in part, at any time during the period commencing on the
date hereof and expiring at earlier of (i) 5:00 p.m. Pittsburgh, Pennsylvania
Time, on May 31, 2006 or (ii) that date which is thirty days after a call of
this Warrant is made by the Company in accordance with the provisions of Section
9 of this Warrant (such earlier date the "Expiration Date"), or, if such
Expiration Date is a day on which banking institutions in Pittsburgh,
Pennsylvania are authorized by law to close, then on the next succeeding day
that shall not be such a bank holiday, by presentation and surrender of this
Warrant certificate to the Company at its principal office, or at the office of
its stock transfer agent, if any, with the Warrant Exercise Form attached hereto
duly executed and accompanied by payment (either in cash or by certified or
official bank check, payable to the order of the Company) of the aggregate
exercise price (the "Exercise Price") for the number of shares specified in

                                       15
<PAGE>   2

such form and instruments of transfer, if appropriate, duly executed by the
Holder. If this Warrant should be exercised in part only, the Company shall,
upon surrender of this Warrant certificate for cancellation, execute and deliver
a new Warrant certificate evidencing the rights of the Holder thereof to
purchase the balance of the shares purchasable hereunder. Upon receipt by the
Company of this Warrant certificate, together with the Exercise Price, at its
office, or by the stock transfer agent of the Company at its office, if any, in
proper form for exercise as described above (and if other than the original
Holder accompanied by proof, satisfactory to counsel for the Company, of the
right of such person or persons to exercise the Warrant), the Holder shall be
deemed to be the holder of record of the shares of Common Stock issuable upon
such exercise, even if the stock transfer books of the Company shall then be
closed or certificates representing such shares of Common Stock shall not have
been delivered to the Holder. The Holder shall pay any and all documentary stamp
or similar issue or transfer taxes payable in respect of the issue or delivery
of shares of Common Stock on exercise of this Warrant. The Company shall
promptly thereafter issue certificate(s) evidencing the Common Stock so
purchased.

Section 2. Reservation of Shares. The Company shall at all times reserve for
issuance and delivery upon exercise of this Warrant all shares of Common Stock
or other shares of capital stock of the Company (and other securities) from time
to time receivable upon exercise of this Warrant. All such shares (and other
securities) shall be duly authorized and, when issued upon exercise and paid for
in accordance with this Warrant, shall be validly issued, fully paid and
non-assessable.

Section 3. No Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant. As to any
fraction of a share which Holder would otherwise be entitled to acquire upon
such exercise of all or a portion of this Warrant, the Company shall pay the
Holder a cash amount equal to the fair market value of such fractional share of
Common Stock in lieu thereof. For purposes of this Warrant, the fair market
value of a share of Common Stock for purposes hereof shall equal the closing
sale price (or if not available the average of the closing bid and asked prices)
on the business day prior to exercise of this Warrant, or, if the Common Stock
is then not publicly traded, then the price determined in good faith by the
Board of Directors of the Company.

Section 4. Transfer.

         4.1 Securities Laws Restrictions on Transfer. Neither this Warrant nor
the Warrant Stock have been registered under the Securities Act of 1933
("Securities Act") or any state securities laws. The Company will not transfer
either this Warrant or the Warrant Stock unless: (i) there is an effective
registration covering such Warrant or such Warrant Stock, as the case may be,
under the Securities Act and applicable states securities laws; (ii) it receives
a letter from an attorney, reasonably acceptable to the Company's board of
directors or its agents, stating that in the opinion of such attorney the
proposed transfer is exempt from registration under the Securities Act and under
all applicable state securities laws; or (iii) the transfer is made pursuant to
Rule 144 under the Securities Act.

         4.2 Conditions of Transfer. Prior to any such proposed transfer, and as
a condition thereto, if such transfer is not made pursuant to an effective
registration statement under the Securities Act the Holder will, if requested by
the Corporation, deliver to the Corporation: (I) an investment covenant signed
by the proposed transferee; (ii) an agreement by such transferee that the
restrictive investment legend set forth above be placed on the certificate or
certificates representing the securities acquired by such transferee; (iii) an
agreement by such transferee that the Corporation may place a "stop transfer
order" with its transfer agent or registrar; and (iv) an agreement by the
transferee to indemnify the Corporation to the same extent as set forth in the
next succeeding Subsection

     (c)  Indemnity. The Holder acknowledges that the Holder understands the
          meanings and legal consequences of this Subsection, and the holder
          hereby agrees to indemnify and hold harmless the Corporation, its
          representatives and each officer and director thereof from and against
          any and all loss, damage or liability (including all attorneys' fees
          and costs incurred in enforcing this indemnity provision) due to or
          arising out of: (I) the inaccuracy of any representation or the breach
          of any warranty of the Holder contained in, or any other breach of,
          this Warrant; (ii) any transfer of any of this Warrant or the Warrant
          Stock in violation of the Securities Act, the Securities Exchange Act
          of 1934, as amended ("Exchange Act"), or the rules and regulations
          promulgated under either of such Acts; (iii) any transfer of this
          Warrant or any of the Warrant Stock in a manner inconsistent with this
          Warrant; or (iv) any untrue statement or omission to state any
          material fact in connection with the investment representations or
          with respect to the facts and representations supplied by the Holder
          to counsel to the Corporation upon which its opinion as to a proposed
          transfer shall have been based.

     (d)  Holdback Period and Transfer. Except as specifically restricted
          hereby, this Warrant and the Warrant Stock issued may be transferred
          by the Holder in whole or in part at any time or from time to time.
          Upon surrender of this Warrant certificate to the Corporation or at
          the office of its stock transfer agent, if any, accompanied by a
          request for transfer of this Warrant to a transferee, and accompanied
          by funds sufficient to pay any documentary stamp or similar issue or
          transfer tax, and upon compliance with the provisions of this Section
          4, the Corporation shall, without charge, execute and deliver a new
          Warrant certificate in the name of such transferee, and this Warrant
          certificate shall promptly be cancelled. Any assignment, transfer,
          pledge, hypothecation or other disposition of this Warrant attempted
          contrary to the provisions of this Warrant, or any levy of execution,
          attachment or other process attempted upon this Warrant, shall be null
          and void and without effect.

Section 5. Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
unless and until this Warrant is exercised. The rights of the Holder are limited
to those expressed in this Warrant and are not enforceable against the Company
except to the extent set forth herein.

Section 6. Anti-Dilution Provisions.

         6.1 Stock Splits, Dividends, Etc.

         6.1.1 If the Company shall at any time subdivide its outstanding shares
of Common Stock (or other securities at the time receivable upon the exercise of
the Warrant) by recapitalization, reclassification or split-up thereof, or if
the Company shall declare a stock dividend or otherwise distribute shares of
Common Stock to its stockholders without receipt of consideration therefor, the
number of shares of Common Stock subject to this Warrant immediately prior to
such subdivision shall be proportionately increased and if the Company shall at
any time combine the outstanding shares of Common Stock by recapitalization,
reclassification or reverse split thereof, the number of shares of Common Stock
subject to this Warrant immediately prior to such combination shall be
proportionately decreased. Any such adjustment and adjustment to the Exercise
Price pursuant to this Section shall be effective at the close of business on
the effective date of such subdivision or combination or if any adjustment is
the result of a stock dividend or distribution then the effective date for such
adjustment based thereon shall be the record date therefor.

         6.1.2 Whenever the number of shares of Common Stock purchasable upon
the exercise of this Warrant is adjusted, as provided in this Section, the
Exercise Price shall be adjusted to the nearest cent by multiplying such
Exercise Price immediately prior to such adjustment by a fraction (i) the
numerator of which shall be the number of shares of Common Stock purchasable
upon the exercise immediately prior to such adjustment, and (ii) the denominator
of which shall be the number of shares of Common Stock so purchasable
immediately thereafter.

         6.2 Adjustment for Reorganization, Consolidation, Merger, Etc. In case
of any reorganization of the Company (or any other Company, the securities of
which are at the time receivable on the exercise of this Warrant) or
reclassification of the Common Stock after the Base Date other than as set forth
in Section 6.1 of this Warrant or in case after such date the Company (or any
such other Company) shall consolidate with or merge into another Company or
convey all or substantially all of its assets to another Company, then, and in
each such case, the Holder of this Warrant upon the exercise as provided in
Section 1 at any time after the consummation of such reorganization,
consolidation, merger, conveyance or reclassification shall be entitled to
receive, in lieu of the securities and property receivable upon the exercise of
this Warrant prior to consummation of such transaction, the securities or
property to which such Holder would have been entitled upon the consummation of
such transaction, had such Holder exercised this Warrant immediately prior
thereto; in each such case, the terms of this Warrant shall be applicable to the
securities or property received upon the exercise of this Warrant after such
consummation.

         6.3 Certificate as to Adjustment. In each case of an adjustment in the
number of shares of Common Stock receivable on the exercise of this Warrant, the
Corporation at its expense shall promptly compute such adjustment in accordance
with the terms of the Warrant and prepare a certificate executed by an officer
of the Corporation setting forth such adjustment and showing the facts upon
which such adjustment is based. The Corporation shall forthwith mail a copy of
each such certificate to each Holder.

         6.4.1 the Company shall take a record of the holders of its Common
Stock (or other securities at the time receivable upon the exercise of the
Warrant) for the purpose of entitling them to receive any dividend (excluding
regularly payable cash dividends declared from time to time by the Company's
Board of Directors) or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities, or to receive any other right , or

         6.4.2 of any plan of reorganization, reclassification, merger,
conveyance of assets, voluntary or involuntary dissolution, liquidation or
winding-up of the Company; or

then, and in each such case, the Company shall mail or cause to be mailed to
each Holder a notice specifying, as the case may be: (i) the date on which a
record is to be taken for the purpose of such dividend, distribution or right,
and stating the amount and character of such dividend, distribution or right; or
(ii) the date on which such reorganization, reclassification, consolidation,
merger, conveyance, dissolution, liquidation or winding-up is to take place, and
the time, if any, to be fixed, as to which the holders of record of Common Stock
(or such other securities at the time receivable upon the exercise of this
Warrant) shall be entitled to exchange their shares of Common Stock (or such
other securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up. Such notice shall be mailed at least
twenty (20) days prior to the date therein specified, and this Warrant may be
exercised prior to said date during the term of the Warrant.

Section 7. Legend and Stop Transfer Orders. Unless the shares of Warrant Stock
have been registered under the Securities Act, upon exercise of this or any
portion of this Warrant and the issuance of any of the shares of Warrant Stock,
the Company shall instruct its transfer agent, if any, to enter stop transfer
orders with respect to such shares, and all certificates representing shares of
Warrant Stock shall bear on the face thereof substantially the following legend:

         "This certificate has not been registered under the Securities Act of
         1933 or applicable state securities laws. The Company will not transfer
         this certificate unless there is an effective registration covering the
         shares represented by this certificate under the Securities Act of 1933
         and all applicable state securities laws or an exemption from
         registration under the Securities Act of 1933 and under all applicable
         state securities laws is then available.

Section 8. Officers' Certificate. Whenever the number or kind of securities
purchasable upon the exercise of this Warrant or the Exercise Price shall be
adjusted as required by the provisions hereof, the Corporation shall forthwith
file with its Secretary or Assistant Secretary at its principal office and with
its stock transfer agent, if any, an officer's certificate showing the adjusted
number of kind of securities purchasable upon the exercise of this Warrant and
the adjusted Exercise Price determined as herein provided and setting forth in
reasonable detail such facts as shall be necessary to show the reason for and
the manner of computing such adjustments. Each such officers certificate shall
be made available at all reasonable times for inspection by the Holder and the
Corporation shall , forthwith after each such adjustment, mail by certified mail
a copy of such certificate to the Holder.

Section 9.        Call Provisions.

         9.1 Call of Warrants. At any time the Company may deliver to the Holder
a Call Notice (as defined in Section 9.3) provided that the closing price of

Section 104.  Acts of Holders.

       (a)  Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent 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 Thirteen, or a combination of such instruments and any such record.
Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments or record or both are delivered to
the Trustee for the appropriate series of Securities 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
(subject to Section 601) conclusive in favor of the Trustee for the appropriate
series of Securities and the Company and any agent of such Trustee or the
Company, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities shall be proved in the manner provided in
Section 1306.

       The Company may at its discretion set a record date for purposes of
determining the identity of Holders of Registered Securities entitled to vote or
consent to any action by vote or consent authorized or permitted under this
Indenture, but the Company shall have no obligation to do so.  If not set by the
Company prior to the first solicitation of Holders of Registered Securities of a
particular series made by any Person in respect of any such action, or, in the
case of any such vote, prior to such vote, the record date for any such action
or vote shall be 30 days prior to the first solicitation of such vote or
consent.  Upon the fixing of such a record date, those persons who were Holders
of Registered Securities at such record date (or their duly designated proxies),
and only those persons, shall be entitled with respect to such Registered
Securities to take such action by vote or consent or to revoke any vote or
consent previously given, whether or not such persons continue to be Holders
after such record date.

       (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 the certificate of any 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 an officer of a corporation or association or a member of a
partnership, or an official of a public or governmental body, on behalf of such
corporation, association, partnership or public or governmental body or by a
fiduciary, such certificate or affidavit shall also constitute sufficient proof
of his authority.

       (c)  The fact and date of the execution by any Person 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 for the appropriate series
of Securities deems reasonably sufficient.

       (d)  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.

       (e)  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

                                      -11-
<PAGE>

such certificate shall be deemed by the Trustee for such Securities 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 such Trustee to be satisfactory. The Trustee for such Securities 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, (2) such Bearer Security is
produced to such Trustee by some other Person, (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 which the Company and the Trustee for such Securities
deem sufficient.

       (f)  Any request, demand, authorization, direction, notice, consent,
waiver or other action by 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 for such
Securities, the Security Registrar, any Paying Agent or the Company in reliance
thereon, whether or not notation of such action is made upon such Security.

Section 105.  Notices, Etc., to Trustee and the 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 for a series of Securities 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 such Trustee at its Corporate
     Trust Office, Attention: Corporate Trustee Administration Department, or if
     sent by facsimile transmission, to a facsimile number provided by the
     Trustee, with a copy mailed, first class postage prepaid to the Trustee
     addressed to it as provided above, or

              (2)  the Company by such Trustee or by any Holder shall be
     sufficient for every purpose hereunder (except as provided in paragraphs
     (3), (4) and (5) of Section 501) if furnished in writing and mailed, first
     class postage prepaid, addressed in the case of the Company to it at the
     address of its principal office specified in the first paragraph of this
     instrument or at any other address previously furnished in writing to such
     Trustee by the Company, or if sent by facsimile transmission, to a
     facsimile number provided to the Trustee by the Company, with a copy
     mailed, first class postage prepaid, to the Company addressed to it as
     provided above.

Section 106.  Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, (1) such
notice shall be sufficiently given (unless otherwise herein expressly provided)
to Holders of Registered Securities if in writing and mailed, first class
postage prepaid, to each Holder affected by such event, at his address as it
appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice; and
(2) such notice shall be sufficiently given (unless otherwise herein expressly
provided) to Holders of Bearer Securities who have filed their names and
addresses with the Trustee for such purpose within the previous two years if in
writing and mailed, first class postage prepaid, to each such Holder at his
address as so filed not later than the latest date and not earlier than the
earliest date prescribed for the giving of such notice, or to all other Holders
of Bearer Securities if published in an Authorized Newspaper on a Business Day
at least twice, the first such publication to be not earlier than the earliest
date, and the second such publication to be not later than the latest date,

                                      -12-
<PAGE>

prescribed herein for the giving of such notice.  Any such notice by publication
shall be deemed to have been given on the date of the first such publication.

     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 of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice mailed in the manner prescribed by this
Indenture shall be conclusively deemed to have been given whether or not
received by any particular Holder. In case by reason of the suspension of
regular mail service or by reason of any other cause it shall be impracticable
to give such notice to Holders of Registered Securities by mail, then such
notification as shall be made with the reasonable approval of the Trustee for
such Securities shall constitute a sufficient notification for every purpose
hereunder.

     In case by reason of the suspension 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 made with the
reasonable approval of the Trustee for such Securities 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 any notice to Holders of Registered Securities given as provided
herein.

     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 for such
Securities, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

Section 107.  Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with the duties
imposed by any of Sections 310 through 317, inclusive, of the Trust Indenture
Act through the operation of Section 318(c) thereof, such imposed duties shall
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the provision
shall be deemed to apply to the Indenture as so modified or excluded, as the
case may be

     Unless otherwise stated with respect to Securities of any series, in any
case where any Interest Payment Date, Redemption Date or Stated Maturity of a
Security of any particular series shall not be a Business Day at any Place of
Payment with respect to Securities of that series, then (notwithstanding any
other provision of this Indenture or of the Securities or coupons) payment of
principal of (and premium, if any) and interest, if any, with respect to such
Security need not be made at such Place of Payment on such date, but may be made

<PAGE>

Officer's Certificate relating thereto or provided in or pursuant to any
supplemental indenture hereto. The terms of such Securities, as set forth above,
may be determined by the Company from time to time if so provided in or
established pursuant to the authority granted in Board Resolutions. All
Securities of any one series need not be issued at the same time, and unless
otherwise provided, a series may be reopened for issuance of additional
Securities of such series.

     Prior to the delivery of a Security of any series in any such form to the
Trustee for the Securities of such series for authentication, the Company shall
deliver to such Trustee the following:

              (1)  The Board Resolutions of the Company by or pursuant to which
     such form of Security have been approved and, if applicable, the
     supplemental indenture by or pursuant to which such form of Security has
     been approved;

              (2)  An Officers' Certificate of the Company dated the date such
     Certificate is delivered to such Trustee satisfying the requirements of
     Sections 102 and 103, and stating that all conditions precedent provided
     for in this Indenture relating to the authentication and delivery of
     Securities in such forms have been complied with; and

              (3)  An Opinion of Counsel satisfying the requirements of Sections
     102 and 103 substantially to the effect that Securities in such forms,
     together with any coupons appertaining thereto, when (a) completed by
     appropriate insertions and executed and delivered by the Company to such
     Trustee for authentication in accordance with this Indenture, (b)
     authenticated and delivered by such Trustee in accordance with this
     Indenture, and (c) issued by the Company in the manner and subject to the
     conditions specified in such Opinion of Counsel, will constitute the legal,
     valid and binding obligations of the Company, subject to the effects of
     applicable bankruptcy, reorganization, fraudulent conveyance, moratorium,
     insolvency and other similar laws generally affecting creditors' rights, to
     general equitable principles, to an implied covenant of good faith and fair
     dealing and to such other qualifications as such counsel shall conclude do
     not materially affect the rights of Holders of such Securities.

Section 302.  Denominations and Currencies.

     Unless otherwise provided with respect to any series of Securities as
contemplated by Section 301, any Registered Securities of a 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 any Bearer Securities of a series other than Bearer Securities issued in
global for (which may be of any denomination) shall be issuable in the
denomination of $5,000, or the equivalent amounts thereof in the case of
Registered Securities and Bearer Securities denominated in a Foreign Currency or
currency unit.

Section 303.  Execution, Authentication, Delivery and Dating.

     The Securities and any related coupons shall be executed on behalf of the
Company by its Chairman of the Board, a Vice Chairman of the Board, or its
President, Chief Executive Officer or one of its Vice Presidents. The Securities
shall be so executed under the corporate seal of the Company reproduced thereon
and attested to by its Secretary or any one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or facsimile.

     Securities and 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

                                      -20-
<PAGE>

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.

     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
coupons appertaining thereto, executed by the Company to the Trustee for the
Securities of such series for authentication, together with a Company Order for
the authentication and delivery of such Securities, and such Trustee, in
accordance with the Company Order, shall authenticate and deliver such
Securities; provided, however, that, during the "restricted period" (as defined
in Section 1.163-5(c)(2)(i)(D)(7) of the United States Treasury Regulations), no
Bearer Security shall be mailed or otherwise delivered to any location in the
United States; and provided, further, that a Bearer Security may be delivered
outside the United States in connection with its original issuance only if the
Person entitled to receive such Bearer Security shall have furnished to the
Trustee for the Securities of such series a certificate substantially in the
form set forth in Exhibit A to this Indenture. If any Security shall be
represented by a permanent Global 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 the original
issuance of such beneficial owner's interest in such permanent Global Security.
Except as permitted by Section 306 or 307, the Trustee for the Securities of a
series shall not authenticate and deliver any Bearer Security unless all
appurtenant coupons for interest then matured other than matured coupons in
default have been detached and cancelled. If all the Securities of any one
series are not to be issued at one time and if a Board Resolution relating to
such Securities shall so permit, such Company Order may set forth procedures
acceptable to the Trustee for the issuance of such Securities, including,
without limitation, procedures with respect to interest rate, Stated Maturity,
date of issuance and date from which interest, if any, shall accrue.

     Notwithstanding any contrary provision herein, if all Securities of a
series are not to be originally issued at one time, it shall not be necessary to
deliver the Board Resolution, Officers' Certificate and Opinion of Counsel
otherwise required pursuant to Sections 102 and 301 at or prior to the time of
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

     Each Registered Security shall be dated the date of its authentication,
and, unless otherwise specified as contemplated by Section 301, each Bearer
Security shall be dated as of the date of original issuance of the first
Security of such series to be issued.

     No Security or coupon appertaining thereto 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 manually executed by the Trustee for such Security or
on its behalf pursuant to Section 614, and such certificate upon any Security
shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder.

     In case any Securities shall have been authenticated, but not delivered, by
the Trustee or the Authenticating Agent for such series then in office, any
successor by merger, conversion or consolidation to such Trustee, or any
successor Authenticating Agent, as the case may be, may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee or successor Authenticating Agent had itself
authenticated such Securities.

     Each Depositary designated pursuant to Section 301 for a Global Security in
registered form must, at the time of its designation and at all times while it
serves as Depositary, be a clearing agency registered under the Exchange Act and
any other applicable statute or regulation.

                                      -21-
<PAGE>

     The Trustee shall have the right to decline to authenticate and deliver any
Securities under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken or if the Trustee in good
faith shall determine that such action would expose the Trustee to personal
liability to existing Holders.

Section 304.  Temporary Securities and Exchange of Securities.

     Pending the preparation of definitive Securities of any particular series,
the Company may execute, and upon Company Order the Trustee for the Securities
of such series shall authenticate and deliver, in the manner specified in
Section 303, temporary Securities which are printed, lithographed, typewritten,
photocopied or otherwise produced, in any denomination, with like terms and
conditions as the definitive Securities of like series in lieu of which they are
issued in registered form or, if authorized, in bearer form with one or more
coupons or without coupons, and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.  Any such
temporary Securities may be in global form, representing such of the Outstanding
Securities of such series as shall be specified therein.

     Except in the case of temporary Securities in global form (which shall be
exchanged only in accordance with the provisions of the following paragraphs or
as otherwise provided in or pursuant to a Board Resolution or a Supplemental
Indenture), if temporary Securities of any particular series are issued, the
Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of such definitive Securities, the
temporary Securities of such series shall be exchangeable for such definitive
Securities of a like Stated Maturity and with like terms and provisions upon
surrender of the temporary Securities of such series, together with all
unmatured coupons and matured coupons in default, if any, 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 particular series, the Company shall execute and (in
accordance with a Company Order delivered at or prior to the authentication of
the first definitive Security of such series) the Trustee for the Securities of
such series or the Global Exchange Agent shall authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of authorized
denominations of the same series and of a like Stated Maturity and with like
terms and provisions; provided, however, unless otherwise specified pursuant to
Section 301, 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 exchanged 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 with like terms and conditions, except as to
payment of interest, if any, authenticated and delivered hereunder.

     Any temporary Global Security and any permanent Global Security shall,
unless otherwise provided therein, be delivered to a Depositary designated
pursuant to Section 301.

     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 Securities represented by any temporary
Global Security of a series of Securities issuable in bearer form may be
exchanged for definitive Securities (subject to the second succeeding paragraph)
or Securities to be represented thereafter by one or more permanent Global
Securities, without interest coupons. On or after the Exchange Date such
temporary Global Security shall be surrendered by the Depositary to the Trustee
for such Security, as the Company's agent for such purpose, or the agent
appointed by the Company pursuant to Section 301 to effect the exchange of the
temporary Global Security for definitive Securities (the "Global Exchange
Agent"), and following such surrender, such Trustee or the Global Exchange Agent
(as authorized by the Trustee as an Authenticating Agent pursuant to Section
614) shall (1) endorse

                                      -22-
<PAGE>

the temporary Global Security to reflect the reduction of its principal amount
by an equal aggregate principal amount of such Security, (2) endorse the
applicable permanent Global Security, if any, to reflect the initial amount, or
an increase in the amount of Securities represented thereby, (3) manually
authenticate such definitive Securities or such permanent Global Security, as
the case may be, (4) subject to Section 303, deliver such definitive Securities
to the Holder thereof or, as the case may be, deliver such permanent Global
Security to the Depositary to be held outside the United States for the accounts
of Euroclear and Clearstream Banking, for credit to the respective accounts at
Euroclear and Clearstream Banking, designated by or on behalf of the beneficial
owners of such Securities (or to such other accounts as they may direct) and (5)
redeliver such temporary Global Security to the Depositary, unless such
temporary Global Security shall have been cancelled in accordance with Section
309 hereof; provided, however, that, unless otherwise specified in such
temporary Global Security, upon such presentation by the Depositary, such
temporary Global Security shall be 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 for
definitive Securities or one or more permanent Global Securities, as the case
may be, and a certificate dated the Exchange Date or a subsequent date and
signed by Clearstream Banking, as to the portion of such temporary Global
Security held for its account then to be exchanged for definitive Securities or
one or more permanent Global Securities, as the case may be, each substantially
in the form set forth in Exhibit B to this Indenture. Each certificate
substantially in the form of Exhibit B hereto of Euroclear or Clearstream
Banking, as the case may be, shall be based on certificates of the account
holders listed in the records of Euroclear or Clearstream Banking, as the case
may be, as being entitled to all or any portion of the applicable temporary
Global Security. An account holder of Euroclear or Clearstream Banking, as the
case may be, desiring to effect the exchange of interest in a temporary Global
Security for an interest in definitive Securities or one or more permanent
Global Securities shall instruct Euroclear or Clearstream Banking, as the case
may be, to request such exchange on its behalf and shall deliver to Euroclear or
Clearstream Banking, as the case may be, a certificate substantially in the form
of Exhibit A hereto and dated no earlier than 15 days prior to the Exchange
Date. Until so exchanged, temporary Global Securities shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities and
permanent Global Securities of the same series authenticated and delivered
hereunder, except as provided in the fourth succeeding paragraph.

     The delivery to the Trustee for the Securities of the appropriate series or
the Global Exchange Agent by Euroclear or Clearstream Banking of any certificate
substantially in the form of Exhibit B hereto may be relied upon by the Company
and such Trustee or the Global Exchange Agent as conclusive evidence that a
corresponding certificate or certificates has or have been delivered to
Euroclear or to Clearstream Banking, as the case may be, pursuant to the terms
of this Indenture.

     On or prior to the Exchange Date, the Company shall deliver to the Trustee
for the Securities of the appropriate series or the Global Exchange Agent
definitive Securities or one or more permanent Global Securities in aggregate
principal amount equal to the principal amount of such temporary Global
Security, executed by the Company in the case of the Securities. At any time, on
or after the Exchange Date, upon 30 days' notice to the Trustee for the
Securities of the appropriate series or the Global Exchange Agent by Euroclear
or Clearstream Banking, as the case may be, acting at the request of or on
behalf of the beneficial owner, a Security represented by a temporary Global
Security or a permanent Global Security, as the case may be, may be exchanged,
in whole or from time to time in part, for definitive Securities without charge
and such Trustee or the Global Exchange Agent shall authenticate and deliver, in
exchange for each portion of such temporary Global Security or such permanent
Global Security, an equal aggregate principal amount of definitive Securities of
the same series of authorized denominations and with like terms and provisions
as the portion of such temporary Global Security or such permanent Global
Security to be exchanged, which, unless the Securities of the series are not
issuable both as Bearer Securities and as Registered Securities, as contemplated
by Section 301, shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified

                                      -23-
<PAGE>

by the beneficial owner thereof; provided, however, that definitive Bearer
Securities shall be delivered in exchange for a portion of the temporary Global
Security or the permanent Global Security only in compliance with the
requirements of the second preceding paragraph. On or prior to the thirtieth day
following receipt by the Trustee for the Securities of the appropriate series or
the Global Exchange Agent of such notice with respect to a Security, or, if such
day is not a Business Day, the next succeeding Business Day, the temporary
Global Security or the permanent Global Security, as the case may be, shall be
surrendered by the Depositary to such Trustee, as the Company's agent for such
purpose, or the Global Exchange Agent to be exchanged in whole, or from time to
time in part, for definitive Securities without charge following such surrender,
upon the request of Euroclear or Clearstream Banking, as the case may be, and
such Trustee or the Global Exchange Agent shall (1) endorse the applicable
temporary Global Security or the permanent Global Security to reflect the
reduction of its principal amount by the aggregate principal amount of such
Security, (2) in accordance with procedures acceptable to the Trustee cause the
terms of such Security and coupons, if any, to be entered on a definitive
Security, (3) manually authenticate such definitive Security and (4) if a Bearer
Security is to be delivered, deliver such definitive Security outside the United
States to Euroclear or Clearstream Banking, as the case may be, for or on behalf
of the beneficial owner thereof, in exchange for a portion of such permanent
Global Security.

     Unless otherwise specified in such temporary Global Security or permanent
Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security or permanent Global
Security, except that a Person receiving definitive Securities must bear the
cost of any taxes, 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 Banking.  Definitive Securities in
bearer form to be delivered in exchange for any portion of a temporary Global
Security or a permanent Global Security shall be delivered only outside the
United States.

     Until exchanged in full as hereinabove provided, any temporary Global
Security or permanent Global Security shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities of the same series
and with like terms and conditions, except as to payment of interest, if any,
authenticated and delivered hereunder.  Unless otherwise specified as
contemplated by Section 301, interest payable on such temporary Global Security
on an Interest Payment Date for Securities of such series shall be payable to
Euroclear and Clearstream Banking on such Interest Payment Date upon delivery by
Euroclear and Clearstream Banking to the Trustee for the Securities of the
appropriate series or the Global Exchange Agent in the case of payment of
interest on a temporary Global Security with respect to an Interest Payment Date
occurring prior to the applicable Exchange Date of a certificate or certificates
substantially in the form set forth in Exhibit C to this Indenture, for credit
without further interest on or after such Interest Payment Date to the
respective accounts of the Persons who are the beneficial owners of such Global
Security on such Interest Payment Date and who have, in the case of payment of
interest on a temporary Global Security with respect to an Interest Payment Date
occurring prior to the applicable Exchange Date, each delivered to Euroclear or
Clearstream Banking, as the case may be, a certificate substantially in the form
set forth in Exhibit D to this Indenture.

     Any definitive Bearer Security authenticated and delivered by the Trustee
for the Securities of the appropriate series or the Global Exchange Agent in
exchange for a portion of a temporary Global Security or a permanent Global
Security shall not bear a coupon for any interest which shall theretofore have
been duly paid by such Trustee to Euroclear or Clearstream Banking or by the
Company to such Trustee in accordance with the provisions of this Section 304.

     With respect to Exhibits A, B, C and D to this Indenture, the Company may,
in its discretion and if required or desirable under applicable law, substitute
one or more other forms of such exhibits for such exhibits, eliminate the
requirement that any or all certificates be provided, or change the time that
any certificate may be required, provided that such substitute form or forms or
notice of elimination or change

                                      -24-
<PAGE>

of such certification requirement have theretofore been delivered to the Trustee
with a Company Request and such form or forms, elimination or change is
reasonably acceptable to the Trustee.

Section 305.  Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee for the Securities of each series a register (the register maintained in
such office being herein sometimes 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 Trustee for the Securities of each series is hereby
initially appointed "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities of such series as
herein provided.

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

     Except as set forth below, at the option of the Holder, Registered
Securities of any particular series may be exchanged for other Registered
Securities of any authorized denominations, and of a like Stated Maturity and of
a like series and aggregate principal amount and with like terms and conditions
upon surrender of the Registered Securities to be exchanged at such office or
agency.  Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee for such Securities shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.  Except as otherwise specified pursuant to Section 301, Registered
Securities may not be exchanged for Bearer Securities.

     Notwithstanding any other provision of this Section or Section 304, unless
and until it is exchanged in whole or in part for Registered Securities in
definitive form, a Global Security representing all or a portion of the
Registered Securities of a series may not be transferred except as a whole by
the Depositary for such series to a nominee of such Depositary or by a nominee
of such Depositary to such Depositary or another nominee of such Depositary or
by such Depositary or any such nominee to a successor Depositary for such series
or a nominee of such successor Depositary.

     If (but not only if) permitted by the applicable Board Resolution and
(subject to Section 308) set forth in the applicable Officer's Certificate, at
the option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and with like terms and provisions upon
surrender of the Bearer Securities to be exchanged at any office or agency of
the Company in a Place of Payment for that series, with all unmatured coupons
and all matured coupons in default thereto appertaining.  If the Holder of a
Bearer Security is unable to produce any such unmatured coupon or coupons or
matured coupon or coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
(or to the Trustee for the Security in case of matured coupons in default) 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
such 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,

                                      -25-
<PAGE>

interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency of the Company in a Place of
Payment for that series 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 exchange for a Registered Security of the same series and
with like terms and conditions after the close of business at such office or
agency on or after (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 (or, if
such coupon is so surrendered with such Bearer Security, such coupon shall be
returned to the person so surrendering the Bearer Security), and interest or
Defaulted Interest, as the case may be, will not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but will be
payable only to the Holder of such coupon when due in accordance with the
provisions of this Indenture.

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

     If at any time the Depositary for Securities of a series in registered form
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of such series shall no longer be eligible under Section 303, the
Company shall appoint a successor Depositary with respect to the Securities for
such series.  If (i) a successor Depositary for the Securities of such series is
not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility, (ii) the Company delivers to the
Trustee for Securities of such series in registered form a Company Order stating
that the Securities of such series shall be exchangeable, or (iii) an Event of
Default under Section 501 hereof has occurred and is continuing with respect to
the Securities of such series, 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 form 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
Registered 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 Registered
Securities of such series, will authenticate and deliver, Registered Securities
of such series in definitive form 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.

     If specified by the Company pursuant to Section 301 with respect to a
series of Securities in registered form, the Depositary for such series of
Securities may surrender a Global Security for such series of Securities in
exchange in whole or in part for Securities of such series of like tenor and
terms and in definitive form on such terms as are acceptable to the Company and
such Depositary.  Thereupon the Company shall execute, and the Trustee shall
authenticate and deliver, without service charge, (i) to each Person specified
by such Depositary a new Security or Securities of the same series, of like
tenor and terms and of any authorized denomination as requested by such Person
in aggregate principal amount equal to and in exchange for such Person's
beneficial interest in the Global Security; and (ii) to such Depositary a new
Global Security of like tenor and terms and in a denomination equal to the
difference, if

                                      -26-
<PAGE>

any, between the principal amount of the surrendered Global Security and the
aggregate principal amount of Securities delivered to Holders thereof.

     Upon the exchange of a Global Security for Securities in definitive form
representing the aggregate principal amount of such Global Security, such Global
Security shall be cancelled by the Trustee.  Registered Securities issued in
exchange for a Global Security pursuant to this Section shall be registered in
such names and in such authorized denominations as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee in writing.  The Trustee
shall deliver such Registered Security 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 Security presented or surrendered for registration of transfer or
exchange shall (if so required by the Company or the Trustee for such Security)
be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar for such series 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 or 1107 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1104 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 as a 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,
however, that such Registered Security shall be simultaneously surrendered for
redemption.

     Furthermore, notwithstanding any other provision of this Section 305, the
Company will not be required to exchange any Securities if, as a result of the
exchange, the Company would suffer adverse consequences under any United States
law or regulation.

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

     If (i) any mutilated Security or a Security with a mutilated coupon
appertaining thereto is surrendered to the Trustee for such Security or the
Company and the Trustee for a Security receive evidence to their satisfaction of
the destruction, loss or theft of any Security or coupon and (ii) there is
delivered to the Company and such Trustee 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 such Trustee that such Security
or coupon has been acquired by a bona fide purchaser, the Company shall execute
and upon its request such Trustee shall authenticate and deliver, in lieu of any
such

                                      -27-
<PAGE>

destroyed, lost or stolen Security or in exchange for such mutilated Security,
or in exchange for the Security to which a mutilated, destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not mutilated, destroyed, lost
or stolen) a new Security of the same series and in a like principal amount and
of a like Stated Maturity and with like terms and conditions, and bearing a
number not contemporaneously outstanding 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.

     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, pay such Security or coupon (without
surrender thereof except in the case of a mutilated Security or coupon) if the
applicant for such payment shall furnish to the Company and the Trustee for such
Security such security or indemnity as may be required by them to save each of
them harmless, and in case of destruction, loss or theft, evidence satisfactory
to the Company and such Trustee and any agent of any of them of the destruction,
loss or theft of such Security and the ownership thereof; provided, however,
that the 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
all fees and expenses of the Trustee for such Security) connected therewith.

     Every new Security of any series, with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security or in exchange
for any mutilated 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 destroyed,
lost or stolen Security and its coupons, if any, or the destroyed, lost or
stolen coupon shall be at any time enforceable by anyone, and each such new
Security shall be at any time enforceable by anyone, and each such new Security
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of the same series and their
coupons, if any, duly issued hereunder.

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

Section 307.  Payment of Interest; Interest Rights Preserved.

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

     Unless otherwise provided with respect to the Securities of any series,
payment of interest may be made at the Corporate Trust Office or, at the option
of the Company (i) in the case of Registered Securities, may be made by check
mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register, or (ii) in the case of Bearer Securities, upon
presentation and surrender of the appropriate coupon appertaining thereto or by
transfer to an account maintained by the payee with a bank located outside the
United States.  Notwithstanding the foregoing, a Holder of

                                      -28-
<PAGE>

$1,000,000 or more in aggregate principal amount of Securities of any series in
definitive form, whether having identical or different terms and provisions,
having the same Interest Payment Dates will, at the option of the Company, be
entitled to receive interest payments, other than at Maturity, by wire transfer
of immediately available funds if appropriate wire transfer instructions have
been received in writing by the Trustee for the Securities of such series at
least 15 days prior to the applicable Interest Payment Date. Any wire
instructions received by the Trustee for the Securities of such series shall
remain in effect until revoked by the Holder.

     Unless otherwise provided or 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 Banking with
respect to that portion of such permanent Global Security held for its account
by the Depositary.  Each of Euroclear and Clearstream Banking will in such
circumstances credit the interest 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 particular series which is
payable, but is not punctually paid or duly provided for, on any Interest
Payment Date (herein called "Defaulted Interest") shall forthwith cease to be
payable to the registered Holder on the relevant Regular Record Date by virtue
of having been such Holder; and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in clause (1) or (2) below:

            (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Registered Securities of that 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 for the Registered Securities of such series in writing
     of the amount of Defaulted Interest proposed to be paid on each Registered
     Security of that series and the date of the proposed payment, and at the
     same time the Company shall deposit with such Trustee an amount of money in
     the currency or currency unit 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 as provided in Sections 311(b) and
     311(d)), equal to the aggregate amount proposed to be paid in respect of
     such Defaulted Interest or shall make arrangements satisfactory to such
     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 such Trustee shall fix a Special Record Date for the payment of
     such Defaulted Interest which shall not be 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 such Trustee of the notice of the proposed
     payment. Such Trustee shall promptly notify the Company of such Special
     Record Date and, in the name and at the expense of the Company, shall cause
     notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor to be mailed, first-class postage prepaid, to each
     Holder of Registered Securities of that series at his address as it appears
     in the Security Register not less than 10 days prior to such Special Record
     Date. Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been mailed as aforesaid, such
     Defaulted Interest shall be paid to the Persons in whose names the
     Registered Securities of that series (or their respective Predecessor
     Securities) are registered 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
     Registered Securities of any particular series in any other lawful manner
     not inconsistent with the requirements of any securities exchange on which
     the Registered Securities may be listed, and upon such notice as may be
     required by such exchange, if, after notice is given by the Company to the
     Trustee for the

                                      -29-
<PAGE>

     Securities of such series of the proposed manner of payment pursuant to
     this clause, such manner of payment shall be deemed practicable by such
     Trustee.

     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.  Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee for such Security and any agent of the
Company or such Trustee may treat the Person in whose name any such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 307) interest, if
any, on such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and none of the Company, such Trustee or any agent of the
Company or such 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 for such Security and any agent of
the Company or such Trustee may treat the bearer of any Bearer Security and the
bearer of any coupon as the absolute owner of such Bearer Security or coupon for
the purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not such Security or coupon be overdue, and none
of the Company, such Trustee or any agent of the Company or such 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 Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

Section 309.  Cancellation.

     All Securities and coupons surrendered for payment, redemption,
registration of transfer or exchange, or delivered in satisfaction of any
sinking fund payment, shall, if surrendered to any Person other than the Trustee
for such Securities, be delivered to such Trustee and, in the case of Registered
Securities and matured coupons, shall be promptly cancelled by it.  All Bearer
Securities and unmatured coupons so delivered to the Trustee for such Securities
shall be cancelled by such Trustee.  The Company may at any time deliver to the
Trustee for Securities of a series for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly cancelled
by such Trustee.  Notwithstanding any other provision of this Indenture to the
contrary, in the case of a series, all the Securities of which are not to be
originally issued at one time, a Security of such series shall not be deemed to
have been Outstanding at any time hereunder if and to the extent that,
subsequent to the authentication and delivery thereof, such Security is
delivered to the Trustee for such Security for cancellation by the Company or
any agent thereof upon the failure of the original purchaser thereof to make
payment therefor against delivery thereof, and any Security so delivered to such
Trustee shall be promptly cancelled by it.  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 and coupons held by the Trustee for such Securities shall be disposed
of by such Trustee in accordance with its standard procedures and a certificate
of disposition evidencing such disposition of Securities and coupons shall be
provided to the Company by such Trustee.  In the case of any temporary Global
Security, which shall be disposed of if the entire aggregate principal amount of
the Securities represented thereby has been exchanged, the certificate of
disposition shall state that all certificates required pursuant to Section 304
hereof,

                                      -30-
<PAGE>

substantially in the form of Exhibit B hereto (or in the form of any substitute
exhibit as provided in the last paragraph of Section 304), to be given by
Euroclear or Clearstream Banking, have been duly presented to the Trustee for
such Securities by Euroclear or Clearstream Banking, as the case may be.
Permanent Global Securities shall not be disposed of until exchanged in full for
definitive Securities or until payment thereon is made in full.

Section 310.  Computation of Interest.

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

Section 311.  Currency and Manner of Payments in Respect of Securities.

     Unless otherwise specified in accordance with Section 301 with respect to
any series of Securities, the following provisions shall apply:

     (a)  Except as provided in paragraphs (b) and (d) below, the principal of
(and premium, if any) and interest on Securities of any series denominated in a
Foreign Currency or currency unit will be payable by the Company in Dollars
based on the equivalent of that Foreign Currency or currency unit converted into
Dollars in the manner described in paragraph (c) below.

     (b)  It may be provided pursuant to Section 301 with respect to Registered
Securities of any series denominated in a Foreign Currency or currency unit that
Holders shall have the option, subject to paragraph (d) below, to receive
payments of principal of (and premium, if any) and interest on such Registered
Securities in such Foreign Currency or currency unit by delivering to the
Trustee (or to any duly appointed Paying Agent) for the Registered Securities of
that series a written election, to be in form and substance satisfactory to such
Trustee (or to any such Paying Agent), not later than the close of business on
the Election Date immediately preceding the applicable payment date. If a Holder
so elects to receive such payments in such Foreign Currency or currency unit,
such election will remain in effect for such Holder until changed by such Holder
by written notice to the Trustee (or to any such Paying Agent) for the
Registered Securities of that series; provided, however, that 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 provided, further, that no such change or
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,
the Company has exercised any defeasance, satisfaction or discharge options
pursuant to Article Four or notice of redemption has been given by the Company
pursuant to Article Eleven. If any Holder makes any such election, such election
will not be effective as to any transferee of such Holder and such transferee
shall be paid in Dollars unless such transferee makes an election as specified
above; provided, however, that such election, if in effect while funds are on
deposit with respect to the Registered Securities of such series as described in
Section 404 or Section 405, will be effective on any transferee of such Holder
unless otherwise specified pursuant to Section 301 for such Registered
Securities. Any Holder of any such Registered Security who shall not have
delivered any such election to the Trustee (or to any duly appointed Paying
Agent) for the Registered Securities of such series not later than the close of
business on the applicable Election Date will be paid the amount due on the
applicable payment date in Dollars.

     (c)  With respect to any Registered Securities of any series denominated in
a Foreign Currency or currency unit and payable in Dollars, the amount of
Dollars so payable will be determined by the Currency Determination Agent based
on the highest indicative quotation in The City of New York selected by the
Currency Determination Agent at approximately 11:00 A.M., New York City time, on
the

                                      -31-
<PAGE>

second Business Day preceding the applicable payment date. Such selection shall
be made from among the quotations appearing on the bank composite or multi-
contributor pages of the Reuters Monitor Foreign Exchange Service or, if not
available, the Telerate Monitor Foreign Exchange Service, for three (or two if
three are not available) major banks in New York City. The first three (or two)
such banks selected by the Currency Determination Agent which are offering
quotes on the Reuters Foreign Exchange Service shall be used. If such quotations
are unavailable from either such foreign exchange service, such selection shall
be made from the quotations received by the Currency Determination Agent from no
more than three nor less than two recognized foreign exchange dealers in The
City of New York selected by the Currency Determination Agent and approved by
the Company (one of which may be the Currency Determination Agent) for the
purchase by the quoting dealer, for settlement on such payment date, of the
aggregate amount of the Foreign Currency or currency unit payable on such
payment date in respect of all Registered Securities denominated in such Foreign
Currency or currency unit and for which the applicable dealer commits to execute
a contract. If fewer than two such bid quotations are available at 11:00 a.m.,
New York City time, on the second Business Day preceding the applicable payment
date, such payment will be based on the Market Exchange Rate as of the second
Business Day preceding the applicable payment date. If the Market Exchange Rate
for such date is not then available, payments shall be made in the Foreign
Currency or currency unit. All currency exchange costs associated with any
payment in Dollars on any such Registered Securities will be borne by the Holder
thereof by deductions from such payment.

     (d)  If a Conversion Event occurs with respect to a Foreign Currency or
currency unit in which Registered Securities of any series are payable, then
with respect to each date for the payment of principal of (and premium, if any)
and interest on the Registered Securities of that series occurring after the
last date on which such Foreign Currency or currency unit was used, the Company
may make such payment in Dollars. The Dollar amount to be paid by the Company to
the Trustee for the Registered Securities of such series and by such Trustee or
any Paying Agent for the Registered Securities of such series to the Holders of
such Registered Securities with respect to such payment date shall be determined
by the Currency Determination Agent on the basis of the Market Exchange Rate as
of the second Business Day preceding the applicable payment date or, if such
Market Exchange Rate is not then available, on the basis of the most recently
available Market Exchange Rate, or as otherwise established pursuant to Section
301 with respect to such Notes. Any payment in respect of such Registered
Security made under such circumstances in Dollars will not constitute an Event
of Default hereunder.

     (e)  For purposes of this Indenture the following terms shall have the
following meanings:

          A "Component Currency" shall mean any currency which is a component
     currency of any currency unit.

          "Election Date" shall mean, for the Registered Securities of any
     series, the date specified pursuant to Section 301(14).

     (f)  Notwithstanding any other provisions of this Section 311, the
following shall apply: (i) if the official unit of any Component Currency is
altered by way of combination or subdivision, the number of units of that
currency as a component shall be divided or multiplied in the same proportion,
(ii) if two or more Component Currencies are consolidated into a single
currency, the amounts of those currencies as components shall be replaced by an
amount in such single currency equal to the sum of the amounts of the
consolidated Component Currencies expressed in such a single currency, (iii) if
any Component Currency is divided into two or more currencies, the amount of
that original Component Currency as a component shall be replaced by the amounts
of such two or more currencies having an aggregate value on the date of division
equal to the amount of the former Component Currency immediately before such
division and (iv) in the event of an official redenomination of any currency
(including, without limitation,

                                      -32-
<PAGE>

a currency unit), the obligations of the Company to make payments in or with
reference to such currency on the Registered Securities of any series shall, in
all cases, be deemed immediately following such redenomination to be obligations
to make payments in or with reference to that amount of redenominated currency
representing the amount of such currency immediately before such redenomination.

     (g)  All determinations referred to in this Section 311 made by the
Currency Determination Agent shall be in its sole discretion and shall, in the
absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Holders of the applicable Securities. The Currency
Determination Agent shall promptly give written notice to the Trustee for the
Securities of such series of any such decision or determination. The Currency
Determination Agent shall promptly give written notice to the Trustee of any
such decision or determination. The Currency Determination Agent shall have no
liability for any determinations referred to in this Section 311 made by it.

     (h)  The Trustee for the Securities of a particular series shall be fully
justified and protected in relying and acting upon information received by it
from the Company and the Currency Determination Agent with respect to any of the
matters addressed in or contemplated by this Section 311 and shall not otherwise
have any duty or obligation to determine such information independently.

Section 312.  Appointment and Resignation of Currency Determination Agent.

     (a)  If and so long as the Securities of any series (i) are denominated in
a currency unit or a currency other than Dollars or (ii) may be payable in a
currency unit or a currency other than Dollars, or so long as it is required
under any other provision of this Indenture, then the Company shall maintain
with respect to each such series of Securities, or as so required, a Currency
Determination Agent. The Company shall cause the Currency Determination 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 for the purpose of converting the issued currency or
currency unit into the applicable payment currency or currency unit for the
payment of principal (and premium, if any) and interest, if any, pursuant to
Section 311.

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

     (c)  If the Currency Determination Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Currency
Determination Agent for any cause, with respect to the Securities of one or more
series, the Company, by a Board Resolution, shall promptly appoint a successor
Currency Determination Agent or Currency Determination Agents with respect to
the Securities of that or those series (it being understood that any such
successor Currency Determination Agent may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
only be one Currency Determination Agent with respect to the Securities of any
particular series).

                           Satisfaction and Discharge
                           --------------------------

Section 401.  Option to Effect Legal Defeasance or Covenant Defeasance.

     The Company may, at the option of its Board of Directors evidenced by a
Board Resolution set forth in an Officers' Certificate, at any time, with
respect to the Securities of any series, elect to have either Section 402 or 403
be applied to all of the Outstanding Securities of that series upon compliance
with the conditions set forth below in this Article Four.

Section 402.  Legal Defeasance and Discharge.

     Upon the Company's exercise under Section 401 of the option applicable to
this Section 402, the Company shall be deemed to have been discharged from its
obligations with respect to all Outstanding Securities of the particular series
and any coupons appertaining thereto on the date the conditions set forth below
are satisfied (hereinafter, "Legal Defeasance").  For this purpose, such Legal
Defeasance means that the Company shall be deemed to have paid and discharged
all the obligations relating to the Outstanding Securities of that series and
the Securities of that series, including any coupons appertaining thereto, shall
thereafter be deemed to be "outstanding" only for the purposes of Section 406,
Section 408 and the other Sections of this Indenture referred to below in this
Section 402, and to have satisfied all of its other obligations under such
Securities and any coupons appertaining thereto and this Indenture and cured all
then existing Events of Default (and the Trustee, on demand of and 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 Outstanding Securities of
the particular series and coupons, if any, of such series to receive payments in
respect of the principal of (and premium, if any) and interest, if any, on such
Securities when such payments are due or on the Redemption Date solely out of
the trust created pursuant to this Indenture; (b) the Company's obligations with
respect to such Securities concerning issuing temporary Securities of that
series, or, where relevant, registration of such Securities, mutilated,
destroyed, lost or stolen Securities of that series and the maintenance of an
office or agency for payment and money for Security payments held in trust; (c)
the rights, powers, trusts, duties and immunities of the Trustee for the
Securities of that series, and the Company's obligations in connection
therewith; and (d) this Article Four and the obligations set forth in Section
406 hereof.

     Subject to compliance with this Article Four, the Company may exercise its
option under Section 402 notwithstanding the prior exercise of its option under
Section 403 with respect to the Securities of a particular series and any
coupons appertaining thereto.

Section 403.  Covenant Defeasance.

     Upon the Company's exercise under Section 401 of the option applicable to
this Section 403, the Company shall be released from any obligations under the
covenants contained in Sections 704, 801 and 1007 hereof with respect to the
Outstanding Securities of the particular series, along with any additional
covenants contained in such Security or any Supplemental Indenture in connection
therewith, on and after the date the conditions set forth below are satisfied
(hereinafter, "Covenant Defeasance"), and the Securities of that series and any
coupons appertaining thereto shall thereafter be deemed not "Outstanding" for
the purposes of any direction, waiver, consent or declaration or act of Holders
(and the consequences of any thereof) in connection with such covenants, but
shall continue to be deemed "Outstanding" for all other purposes hereunder (it
being understood that such Securities shall not be deemed outstanding for
accounting purposes).  For this purpose, such Covenant Defeasance means that,

                                      -34-
<PAGE>

with respect to the Outstanding Securities of that series and any coupons
appertaining thereto, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any 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 Event of Default under subsection
501(3) but, except as specified above, the remainder of this Indenture and the
Securities of that series shall be unaffected thereby.

Section 404.  Conditions to Legal or Covenant Defeasance.

     The following shall be the conditions to the application of either Section
402 or Section 403 to the Outstanding Securities of a particular series:

               (a)  the Company must irrevocably deposit, or cause to be
     irrevocably deposited, with the Trustee for the Securities of that series,
     in trust, for the benefit of the Holders of the Securities of that series,
     cash in the currency or currency unit in which the Securities of that
     series are payable (except as otherwise specified pursuant to Section 301
     for the Securities of that series and except as provided in Sections 311(b)
     and 311(d), in which case the deposit to be made with respect to Securities
     for which an election has occurred pursuant to Section 311(b), or a
     Conversion Event has occurred as provided in Section 311(d), shall be made
     in the currency or currency unit in which the Securities of that series are
     payable as a result of such election or Conversion Event), Government
     Obligations or a combination thereof in such amounts as will be sufficient,
     in the opinion of an internationally recognized firm of independent public
     accountants, to pay the principal of (and premium, if any) and interest, if
     any, due on the outstanding Securities of that series and any related
     coupons at the Stated Maturity, or on the applicable Redemption Date, as
     the case may be, with respect to the outstanding Securities of that series
     and any related coupons;

               (b)  in the case of Legal Defeasance, the Company shall have
     delivered to the Trustee for the Securities of that series an Opinion of
     Counsel in the United States reasonably acceptable to such Trustee
     confirming that, subject to customary assumptions and exclusions, (1) the
     Company has received from, or there has been published by, the U.S.
     Internal Revenue Service a ruling or (2) since the Issue Date, 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 of Counsel in the United
     States shall confirm that, subject to customary assumptions and exclusions,
     the Holders of the Outstanding Securities of that series will not recognize
     income, gain or loss for U.S. federal income tax purposes as a result of
     such Legal Defeasance and will be subject to U.S. federal income tax on the
     same amounts, in the same manner and at the same times as would have been
     the case if such Legal Defeasance had not occurred;

               (c)  in the case of Covenant Defeasance, the Company shall have
     delivered to the Trustee for the Securities of that series an Opinion of
     Counsel in the United States reasonably acceptable to such Trustee
     confirming that, subject to customary assumptions and exclusions, the
     Holders of the Outstanding Securities of that series will not recognize
     income, gain or loss for U.S. federal income tax purposes as a result of
     such Covenant Defeasance and will be subject to such 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;

               (d)  no Event of Default or event which with the giving of notice
     or the lapse of time, or both, would become an Event of Default with
     respect to the Securities of that series shall have

                                      -35-
<PAGE>

     occurred and be continuing on the date of such deposit and no Event of
     Default under Section 501(5) or Section 501(6) shall have occurred and be
     continuing on the 123rd day after such date;

               (e)  such Legal Defeasance or Covenant Defeasance shall not
     result in a breach or violation of, or constitute a default under any
     material agreement or instrument to which the Company is a party or by
     which the Company is bound;

               (f)  the Company shall have delivered to the Trustee for the
     Securities of that series an Officers' Certificate and an Opinion of
     Counsel in the United States (which opinion of counsel may be subject to
     customary assumptions and exclusions) each stating that all conditions
     precedent provided for or relating to the Legal Defeasance or the Covenant
     Defeasance, as the case may be, have been complied with.

Section 405.  Satisfaction and Discharge of Indenture.

     This Indenture will be discharged and will cease to be of further effect as
to all Securities of any particular series issued hereunder when either (i) all
Securities of that series theretofore authenticated and delivered and all
coupons, if any, appertaining thereto (except (A) coupons appertaining to Bearer
Securities surrendered for exchange for Registered Securities and maturing after
such exchange, whose surrender is not required or has been waived as provided in
Section 305, (B) lost, stolen or destroyed Securities or coupons of such series
which have been replaced or paid as provided in Section 306, (C) coupons
appertaining to Securities called for redemption and maturing after the relevant

(D) Securities and coupons of such series for whose payment money has
theretofore been deposited in trust and thereafter repaid to the Company or
discharged from such trust, as provided in the last paragraph of Section 1003)
have been delivered to the Trustee for the Securities of that series for
cancellation or (ii) (A) all Securities of that series and any coupons
appertaining thereto not theretofore delivered to Trustee for cancellation are
due and payable by their terms within one year or have become due and payable by
reason of the making of a notice of redemption and the Company has irrevocably
deposited or caused to be deposited with such Trustee as trust funds in trust an
amount of cash in any combination of currency or currency unit 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 as provided in Sections
311(b) and 311(d), in which case the deposit to be made with respect to
Securities for which an election has occurred pursuant to Section 311(b) or a
Conversion Event has occurred as provided in Section 311(d), shall be made in
the currency or currency unit in which such Securities are payable as a result
of such election or Conversion Event) sufficient to pay and discharge the entire
indebtedness on such Securities and coupons not theretofore delivered to the
Trustee for the Securities of that series for cancellation for principal (and
premium, if any) and accrued and unpaid interest, if any, to the Stated Maturity
or Redemption Date, as the case may be; (B) no Event of Default or event which
with the giving of notice or the lapse of time, or both, would become an Event
of Default shall have occurred and be continuing on the date of such deposit and
no Event of Default under Section 501(5) or Section 501(6) shall have occurred
and be continuing on the 123rd day after such date; (C) the Company has paid, or
caused to be paid, all sums payable by it under this Indenture; and (D) the

Date, as the case may be. In addition, the Company must deliver an Officers'
Certificate and an Opinion of Counsel to the Trustee for the Securities of that
series stating that all conditions precedent to satisfaction and discharge have
been satisfied.

Section 406.  Survival of Certain Obligations.

     Notwithstanding the satisfaction and discharge of this Indenture and of the
Securities of a particular series referred to in Sections 401, 402, 404, or 405,
the respective obligations of the Company and the Trustee for the Securities of
a particular series under Sections 303, 304, 305, 309, 407, 408, 409, 410, and
508, Article Six, and Sections 701, 702, 1002, 1003, 1004 and 1006, shall
survive with respect to Securities of that series until the Securities of that
series are no longer outstanding, and thereafter the obligations of the Company
and the Trustee for the Securities of a particular series with respect to that
series under Sections 407, 408, 409, and 410 shall survive. Nothing contained in
this Article Four shall abrogate any of the obligations or duties of the Trustee
of any series of Securities under this Indenture.

     Notwithstanding the satisfaction of the conditions set forth in Sections
404 or 405 with respect to all the Securities of any series not payable in
Dollars, upon the happening of any Conversion Event the Company shall be
obligated to make the payments in Dollars required by Section 311(d) to the
extent that the Trustee is unable to convert any Foreign Currency or currency
unit or currency unit in its possession pursuant to Sections 404 or 405 into the
Dollar equivalent of such Foreign Currency or currency unit, as the case may be.
If, after the deposits referred to in Sections 404 or 405 have been made, (x)
the Holder of a Security is entitled to, and does, elect pursuant to Section
311(b) to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Sections 404 or 405 was made, or (y) a Conversion
Event occurs as contemplated in Section 311(d), then the indebtedness
represented by such Security shall be fully discharged to the extent that the
deposit made with respect to such Security shall be converted into the currency
or currency unit in which such Security is payable.  The Trustee shall return to
the Company any non-converted funds or securities in its possession after such
payments have been made.

Section 407.  Acknowledgment of Discharge by Trustee.

     Subject to Section 410, after (i) the conditions of Section 404 or 405 have
been satisfied with respect to the Securities of a particular series, (ii) the
Company has paid or caused to be paid all other sums payable hereunder by the
Company and (iii) the Company has delivered to the Trustee for the Securities of
that series an Officers' Certificate and an Opinion of Counsel, each stating
that all conditions precedent referred to in clause (i) above relating to the
satisfaction and discharge of this Indenture have been complied with, the
Trustee for the Securities of that series upon written request shall acknowledge
in writing the discharge of all of the Company's obligations under this
Indenture except for those surviving obligations specified in this Article Four.

Section 408.  Application of Trust Moneys.

     All money and Government Obligations deposited with the Trustee for the
Securities of a particular series pursuant to Section 404 or 405 in respect of
the Securities of that series shall be held in trust and applied by it, in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent as the Trustee may
determine, to the Holders of the Securities and all related coupons of all sums
due and to become due thereon for 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.

     The Company shall pay and indemnify the Trustee for the Securities of a
particular series against any tax, fee or other charge imposed on or assessed
against the Government Obligations deposited pursuant to Section 404 or 405 with
respect to the Securities of that series or the principal and interest

                                      -37-
<PAGE>

received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of outstanding Securities of that
series.

Section 409.  Repayment to the Company; Unclaimed Money.

     The Trustee and any Paying Agent for a series of Securities shall promptly
pay or return to the Company upon Company Order any cash or Government
Obligations held by them at any time that are not required for the payment of
the principal of (and premium, if any) and interest, if any, on the Securities
and all related coupons for Securities of that series for which cash or
Government Obligations have been deposited pursuant to Section 404 or 405.

     Any money deposited with the Trustee or any Paying Agent for the Securities
of any series, or then held by the Company, in trust for the payment of the
principal of (and premium, if any) and interest, if any, on any Security of any
particular series and all related coupons appertaining thereto and remaining
unclaimed for two years after such principal (and premium, if any) and interest,
if any, has become due and payable shall, unless otherwise required by mandatory
provisions of applicable escheat, or abandoned or unclaimed property law, be
paid to the Company on Company Request or (if then held by the Company) shall be
discharged from such trusts; and the Holder of such Security and all related
coupons shall, thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of such 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 such Trustee or
such Paying Agent, before being required to make any such repayment may give
written notice to the Holder of such Security in the manner set forth in Section
106, 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, unless otherwise required
by mandatory provisions of applicable escheat, or abandoned or unclaimed
property law, be repaid to the Company, as the case may be.

Section 410.  Reinstatement.

     If the Trustee or Paying Agent for a series of Securities is unable to
apply any cash or Government Obligations, as applicable, in accordance with
Section 402, 403, 404 or 405 by reason of any legal proceeding or by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under this Indenture and the Securities of that series shall be revived and
reinstated as though no deposit had occurred pursuant to Section 402, 403, 404
or 405 until such time as the Trustee or Paying Agent for that series is
permitted to apply all such cash or Government Obligations in accordance with
Section 402, 403, 404 or 405; provided, however, that if the Company has made
any payment of principal (and premium, if any) and interest, if any, on any
Securities and any related coupons because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities and such coupons to receive such payment from the cash or
Government Obligations, as applicable, held by such Trustee or Paying Agent.

     specifically dealt with) and continuance of such default or breach for a
     period of 60 days after there has been given, by registered or certified

     the Company and such Trustee by the Holders of at least 25% in principal
     amount of the Outstanding Securities of that series a written notice

     maturity of Securities of another series or any other indebtedness for
     borrowed money of the Company or any of its Subsidiaries, in an aggregate

     or instruments under which such indebtedness is issued or secured, if such
     indebtedness has not been discharged in full or such acceleration is not

     registered or certified mail, to the Company by the Trustee for the
     Securities of such series or to the Company and such Trustee by the Holders
     of at least 25% in principal amount of the Outstanding Securities of that
     series a written notice specifying such default or breach and requiring it
     to be remedied and stating that such notice is a "Notice of Default"

             (5)  the Company or any of its Principal Subsidiaries shall
     commence any case or proceeding seeking to have an order for relief entered
     on its behalf as debtor or to adjudicate it as bankrupt or insolvent or
     seeking reorganization, liquidation, dissolution, winding-up, arrangement,
     composition or readjustment of its debts or any other relief under any
     bankruptcy, insolvency, reorganization, liquidation, dissolution,

     or the Company or any of its Principal Subsidiaries shall apply for a
     receiver, custodian or trustee (other than any trustee appointed as a
     mortgagee or secured party in connection with the issuance of indebtedness

     of its property; or the Company or any of its Principal Subsidiaries shall
     make a general assignment for the benefit of creditors; or the Company or
     any of its Principal Subsidiaries shall take any corporate action in
     furtherance of any of the foregoing; or

             (6)  an involuntary case or other proceeding shall be commenced

     or its debts under any bankruptcy, insolvency or other similar law now or
     hereafter in effect seeking the appointment of a trustee, receiver,
     liquidator, custodian or similar official of the Company or any of its
     Principal Subsidiaries or any substantial part of either's property; and
     such case or other proceeding (A) results in the entry of an order for

     Board Resolution with respect to Securities of that series. Section 502.
     Acceleration of Maturity; Rescission and Annulment.

Section 502. Acceleration of Maturity; Recission and Annulment.

     If an Event of Default with respect to any particular series of Securities
and any related coupons occurs and is continuing (other than an Event of Default
described in Section 501(5) or 501(6) with respect to the Company), then and in
every such case either the Trustee for the Securities of such series or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the entire principal amount (or, in the case of (i)
OID Securities, such lesser amount as may be provided for in the terms of that
series or (ii) Indexed Securities, the amount determined in accordance with the
specified terms of those Securities) of all the Securities of that series, to be
due and payable immediately, by a notice in writing to the Company (and to such
Trustee if given by Holders), and upon any such declaration of acceleration such
principal or such lesser amount, as the case may be, together with accrued
interest and all other amounts owing hereunder, shall become immediately due and
payable, without presentment, demand, protest or notice of any kind, all of
which are hereby expressly waived.

     If any Event of Default specified in Section 501(5) or 501(6) occurs with
respect to the Company, all of the unpaid principal amount (or, if the
Securities of any series then outstanding are (i) OID Securities, such lesser
amount as may be provided for in the terms of that series or (ii) Indexed
Securities, the amount determined in accordance with the specified terms of
those Securities) and accrued interest on all Securities of each series then
outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act by the Trustee or any Holder.

     At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee for the Securities of any series as hereinafter provided in this
Article, the Holders of a majority in principal amount of the Outstanding
Securities of that series, by written notice to the Company and such Trustee,
may rescind and annul such declaration and its consequences if:

             (1)  the Company has paid or deposited with such Trustee a sum
     sufficient to pay in the currency or currency unit 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 as provided in
     Sections 311(b) and 311(d)).

             (A)  all overdue interest on all Securities of that series and any
     related coupons;

                                      -40-
<PAGE>

             (B)  the principal of (and premium, if any, on) any Securities of
     that series which have become due otherwise than by such declaration of
     acceleration and interest thereon from the date such principal became due
     at a rate per annum equal to the rate borne by the Securities of such
     series (or, in the case of (i) OID Securities, the Securities' Yield to
     Maturity or (ii) Indexed Securities, the rate determined in accordance with
     the specified terms of those Securities), to the extent that the payment of
     such interest shall be legally enforceable;

             (C)  to the extent that payment of such interest is lawful,
     interest upon overdue interest at a rate per annum equal to the rate borne
     by the Securities of such series (or, in the case of (i) OID Securities,
     the Securities' Yield to Maturity or (ii) Indexed Securities, the rate
     determined in accordance with the specified terms of those Securities); and

             (D)  all sums paid or advanced by such Trustee hereunder and the
     reasonable compensation, expenses, disbursements and advances of such
     Trustee, its agents and counsel and all other amounts due to such Trustee
     under Section 607;

and

             (2)  all Events of Default with respect to the Securities of such
     series, other than the nonpayment of the principal of Securities of that
     series which has become due solely by such acceleration, have been cured or
     waived as provided in Section 513. No such rescission shall affect any
     subsequent default or impair any right consequent thereon.

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

     The Company covenants that if:

             (1)  default is made in the payment of any interest upon any
     Security of any series and any related coupons when such interest becomes
     due and payable and such default continues for a period of 30 days; or

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

the Company will, upon demand of the Trustee for the Securities of such series,
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, with interest upon the
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installments of interest
at a rate per annum equal to the rate borne by such Securities (or, in the case
of (i) OID Securities, the Securities' Yield to Maturity or (ii) Indexed
Securities, the rate determined in accordance with the specified terms of those
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 such Trustee,
its agents and counsel and all other amounts due to such Trustee under Section
607.

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

                                      -41-
<PAGE>

series and collect the moneys adjudged or decreed to be payable in the manner
provided by law out of the property of the Company or any other obligor upon the
Securities of such series, wherever situated.

     If an Event of Default with respect to Securities of any particular series
occurs and is continuing, the Trustee for the Securities of such series may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of that series by such appropriate judicial proceedings as
such 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 relating to the Company or any other obligor upon the
Securities of any series or the property of the Company or of such other obligor
or their creditors, the Trustee for the Securities of such series (irrespective
of whether the principal (or, if the Securities of such series are (i) OID
Securities or (ii) Indexed Securities, such amount as may be due and payable
with respect to such Securities pursuant to a declaration in accordance with
Section 502) of any Security of such series shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether
such Trustee shall have made any demand on the Company for the payment of
overdue principal or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise

             (i)  to file and prove a claim for the whole amount of principal
     (or, if the Securities of such series are (i) OID Securities or (ii)
     Indexed Securities, such amount as may be due and payable with respect to
     such Securities pursuant to a declaration in accordance with Section 502)
     (and premium, if any) and interest, if any, owing and unpaid in respect of
     the Securities of such series and any related coupons and to file such
     other papers or documents as may be necessary or advisable in order to have
     the claims of such Trustee (including any claim for the reasonable
     compensation, expenses, disbursements and advances of such Trustee, its
     agents and counsel and all other amounts due to such Trustee under Section
     607) and of the Holders of the Securities of such series and any related
     coupons 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 receiver, assignee, trustee, liquidator, sequestrator (or other similar
official) in any such judicial proceeding is hereby authorized by each Holder of
Securities and coupons to make such payments to such Trustee, and in the event
that such Trustee shall consent to the making of such payments directly to the
Holders of Securities and coupons, to pay to such Trustee any amount due to it
for the reasonable compensation, expenses, disbursements and advances of such
Trustee, its agents and counsel, and any other amounts due such Trustee under
Section 607.

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

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

     All rights of action and claims under this Indenture or the Securities or
coupons of any series may be prosecuted and enforced by the Trustee for the
Securities of any series without the possession of any of the Securities or
coupons of such series or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by such 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 such Trustee, its agents and counsel and all other
amounts due to such Trustee under Section 607, be for the ratable benefit of the
Holders of the Securities and coupons of such series in respect of which such
judgment has been recovered.

Section 506.  Application of Money Collected.

     Any money collected by the Trustee for the Securities of any series
pursuant to this Article with respect to the Securities or coupons of such
series shall be applied in the following order, at the date or dates fixed by
such 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 of such series, 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 such Trustee under Section
     607;

          Second: To the payment of the amounts then due and unpaid upon the
     Securities and coupons of such series for principal of (and premium, if
     any) and interest, if any, on such Securities in respect of which or for
     the benefit of which such money has been collected, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on such Securities 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 particular 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)  an Event of Default with respect to that series shall have
     occurred and be continuing and such Holder shall have previously given
     written notice to the Trustee for the Securities of such series of such
     default and the continuance thereof;

             (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 for the Securities of such series 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 such Trustee indemnity
     reasonably satisfactory to the Trustee against the costs, expenses and
     liabilities to be incurred in compliance with such request;

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

                                      -43-
<PAGE>

             (5)  no direction inconsistent with such written request has been
     given to such 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 Holders of Securities of
that series shall have any right in any manner whatsoever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb or prejudice the
rights of any other Holders of Securities of that series, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal and ratable benefit of all the Holders of Securities of that series.

Section 508.  Unconditional Right of Holders to Receive Principal (and Premium,
              if any) and Interest, if any.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security or coupon shall have the right which is absolute and unconditional to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest, if any, on such Security 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 right shall not be impaired without the consent of such
Holder.

Section 509.  Restoration of Rights and Remedies.

     If the Trustee for the Securities of any series or any Holder of a Security
or coupon has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to such Trustee or to such Holder, then
and in every such case the Company, such Trustee and the Holders of Securities
or coupons shall, subject to any determination in such proceeding, be restored
severally and respectively to their former positions hereunder, and thereafter
all rights and remedies of such Trustee and such 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 for the Securities of any series or to the Holders of Securities or
coupons is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 511.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee for the Securities of any series or of
any Holder of any Security of such series to exercise any right or remedy
accruing upon any Event of Default with respect to the Securities of such series
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 such Trustee for the Securities or coupons of any series or
to the Holders may be exercised from time to time, and as often as may be deemed
expedient, by such Trustee or by the Holders, as the case may be.

Section 512.  Control by Holders.

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

             (1)  such direction shall not be in conflict with any rule of law
     or with this Indenture and could not involve the Trustee in personal
     liability; and

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

Section 513.  Waiver of Past Defaults.

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

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

             (2)  a default with respect to 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 that series affected.

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

Section 514.  Undertaking for Costs.

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

Section 515.  Waiver of Stay or Extension Laws.

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

                                      -45-
<PAGE>

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 for any series
of Securities, but will suffer and permit the execution of every such power as
though no such law had been enacted.

Section 516.  Judgment Currency.

     If, for the purpose of obtaining a judgment in any court with respect to
any obligation of the Company hereunder or under any Security or any related
coupon, it shall become necessary to convert into any other currency or currency
unit any amount in the currency or currency unit due hereunder or under such
Security or coupon, then such conversion shall be made by the Currency
Determination Agent at the Market Exchange Rate as in effect on the date of
entry of the judgment (the "Judgment Date").  If pursuant to any such judgment,
conversion shall be made on a date (the "Substitute Date") other than the
Judgment Date and there shall occur a change between the Market Exchange Rate as
in effect on the Judgment Date and the Market Exchange Rate as in effect on the
Substitute Date, the Company agrees to pay such additional amounts, if any, as
may be necessary to ensure that the amount paid is equal to the amount in such
other currency or currency unit which, when converted at the Market Exchange
Rate as in effect on the Judgment Date, is the amount due hereunder or under
such Security or coupon.  Any amount due from the Company under this Section 516
shall be due as a separate debt and is not to be affected by or merged into any
judgment being obtained for any other sums due hereunder or in respect of any
Security or coupon.  In no event, however, shall the Company be required to pay
more in the currency or currency unit due hereunder or under such Security or
coupon at the Market Exchange Rate as in effect on the Judgment Date than the
amount of currency or currency unit stated to be due hereunder or under such
Security or coupon so that in any event the Company's obligations hereunder or
under such Security or coupon will be effectively maintained as obligations in
such currency or currency unit, and the Company shall be entitled to withhold
(or be reimbursed for, as the case may be) any excess of the amount actually
realized upon any such conversion on the Substitute Date over the amount due and

                                  The Trustee
                                  -----------

Section 601.  Certain Duties and Responsibilities.

        (a)  Except during the continuance of an Event of Default with respect
to the Securities of any series for which the Trustee is serving as such,

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

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

                                      -46-
<PAGE>

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

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

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

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

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

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

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

Section 602.  Notice of Defaults.

     Within 90 days after the occurrence of any default hereunder with respect
to Securities of any particular series, the Trustee for the Securities of such
series shall give to Holders of Securities of that series, in the manner set
forth in Section 106, notice of such default known to such 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 that series, or in the deposit of any
sinking fund payment with respect to Securities of that series, such 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 such Trustee in good faith determines that the
withholding of such notice is in the interest of the Holders of Securities of
that series and related coupons.  For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of that series.

     (h)  the Trustee shall not be liable for any action taken, suffered, or
     omitted to be taken by it in good faith and reasonably believed by it to be
     authorized or within the discretion or rights or powers conferred upon it
     by this Indenture;

     (i)  the Trustee shall not be deemed to have notice of any default or Event

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

Authenticating Agent, Paying Agent, Security Registrar or such other agent.

           (1)  to pay to the Trustee for any series of Securities as the
     Company and the Trustee shall agree in writing from time to time such
     compensation in Dollars for all services rendered by it hereunder as shall

     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 for any series of Securities in Dollars upon its request for all
     reasonable expenses, disbursements and advances incurred or made by such
     Trustee in accordance with any provision of this Indenture (including the

     and counsel), except any such expense, disbursement or advance as may be

     hold them harmless against, any loss, damage, claims, liability or expense
     incurred without negligence or bad faith on their part, arising out of or
     in connection with the acceptance or administration of this trust,

                                      -49-
<PAGE>

     whether asserted by the Company or any Holder or any other Person, or
     liability in connection with the exercise or performance of any of their
     powers or duties hereunder.

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

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

Section 608.  Disqualification; Conflicting Interests.

     The Trustee for the Securities shall be subject to the provisions of
Section 310(b) of the Trust Indenture Act during the period of time required
thereby.  Nothing herein shall prevent the Trustee from filing with the
Commission the application referred to in the penultimate paragraph of Section
310(b) of the Trust Indenture Act.  In determining whether the Trustee has a
conflicting interest as defined in Section 310(b) of the Trust Indenture Act
with respect to the Securities of any series, there shall be excluded Securities
of any particular series of Securities other than that series.

Section 609.  Corporate Trustee Required; Different Trustees for Different

     business under the laws of the United States of America, any state thereof,
     or the District of Columbia, authorized under such laws to exercise
     corporate trust powers, and subject to supervision or examination by
     Federal or State authority, or

                     (ii) a corporation or other Person organized and doing
     business under the laws of a foreign government that is permitted to act as
     Trustee pursuant to a rule, regulation, or other order of the Commission,
     authorized under such laws to exercise corporate trust powers, and subject
     to supervision or examination by authority of such foreign government or a
     political subdivision thereof substantially equivalent to supervision or
     examination applicable to United States institutional trustee, having 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
     requirements of the aforesaid 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. Neither the
     Company nor any Person directly or indirectly controlling, controlled by,
     or under the common control of the Company shall serve as Trustee for the
     Securities. 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 hereunder specified in this Article.

Section 610.  Resignation and Removal; Appointment of Successor.

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

        (b)  The Trustee for the Securities of any series may resign at any time
with respect to the Securities of such series by giving written notice thereof
to the Company. If the instrument of acceptance by a successor Trustee required
by Section 611 shall not have been delivered to the Trustee for the Securities
of such series within 60 days after the giving of such notice of resignation,
the resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

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

        (d)  If at any time:

                   (1)  the Trustee for the Securities of any series shall fail
     to comply with Section 310(b) of the Trust Indenture Act pursuant to
     Section 608 hereof after written request therefor by the Company or by any
     Holder who has been a bona fide Holder of a Security of such series for at
     least six months, unless the Trustee's duty to resign is stayed in
     accordance with the provisions of Section 310(b) of the Trust Indenture
     Act, or

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

                   (3)  such Trustee shall become incapable of acting or shall
     be adjudged a bankrupt or insolvent or a receiver of such Trustee or of its
     property shall be appointed or any public officer shall take charge or
     control of such 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
     such Trustee and appoint a successor Trustee or (ii) subject to Section
     514, 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
     removal of such Trustee and the appointment of a successor Trustee.

        (e)  If the Trustee for the Securities of any series shall resign, be
removed or become incapable of acting, or if a vacancy shall occur in the office
of Trustee for the Securities of any series for any cause, the Company, by a
Board Resolution, shall promptly appoint a successor Trustee with respect to the
Securities of such series and shall comply with the applicable requirements of
Section 611. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of such series shall have not been appointed by the
Company pursuant to this Section 610, then a successor Trustee may 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. If
no successor Trustee for the Securities of such series shall have been so
appointed by the Company or the Holders and shall have accepted appointment in
the manner required by Section 611, and if such Trustee to be replaced is still
incapable of acting, 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,

                                      -51-
<PAGE>

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 in the
manner and to the extent provided in Section 106. Each notice shall include the
name of the successor Trustee with respect to the Securities of that series and
the address of its Corporate Trust Office.

Section 611.  Acceptance of Appointment by Successor.

        (a)  Every such successor Trustee appointed hereunder with respect to
the Securities of any series 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 each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any other
such Trustee; and upon the execution and delivery of such supplemental indenture
the resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on
request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

        (c)  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in Subsections (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 for the Securities of any series
shall be qualified and eligible under this Article.

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

     Any corporation into which the Trustee for the Securities of any series 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 Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of such Trustee, shall be the successor of such
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 or the
Authenticating Agent for such series then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee or Authenticating
Agent, as the case may be, may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee or
successor Authenticating Agent had itself authenticated such Securities.

Section 613.  Preferential Collection of Claims Against Company.

     The Trustee is subject to Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship listed in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent indicated.

Section 614.  Authenticating Agents.

     At any time when any of the Securities of any series remain Outstanding,
the Trustee for the Securities of such series may, subject to its sole
discretion, appoint one or more Authenticating Agents with respect to the
Securities of such series, which may include the Company or any Affiliate of the
Company, with power to act on the Trustee's behalf and subject to its discretion
in the authentication and delivery of Securities of such series in connection
with transfers and exchanges under Sections 304, 305 and 1107 as fully to all
intents and purposes as though such Authenticating Agent had been expressly
authorized by those Sections of this Indenture to authenticate and deliver
Securities of such series. For all purposes of this Indenture, the
authentication and delivery of Securities of such series by an Authenticating
Agent for such Securities pursuant to this Section shall be deemed to be
authentication and delivery of such Securities "by the Trustee" for the
Securities of such series. Any such Authenticating Agent shall at all times be a
corporation organized and doing business under the laws of the United States or
of any State, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually pursuant to law or the
requirements of such 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 an Authenticating Agent for any
series of Securities shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the parties hereto or the Authenticating Agent or such successor
corporation.

                                      -53-
<PAGE>

     Any Authenticating Agent for any series of Securities may resign at any
time by giving written notice of resignation to the Trustee for such series and
to the Company. The Trustee for any series of Securities may at any time
terminate the agency of any Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company in the manner set
forth in Section 105. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent for any series of
Securities shall cease to be eligible under this Section, the Trustee for such
series may appoint a successor Authenticating Agent, shall give written notice
of such appointment to the Company and shall give written notice of such
appointment to all Holders of Securities of such series in the manner set forth
in Section 106. Any successor Authenticating Agent, upon acceptance of its
appointment hereunder, shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

     If an appointment with respect to one or more series of Securities is made
pursuant to this Section, the Securities of such series may have endorsed

     With respect to each particular series of Securities, the Company will
furnish or cause to be furnished to the Trustee for the Securities of such
series,

     (a)  semi-annually, not more than 15 days after each Regular Record Date
relating to Securities of each series at the time Outstanding (or, if there is
no Regular Record Date relating to that series, on June 30 and December 31), a
list, in such form as such Trustee may reasonably require, containing all the

form and content, and

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

excluding from any such list names and addresses received by such Trustee in its

Section 702.  Preservation of Information; Communications to Holders.

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

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

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

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

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

       (c)  Every Holder of Securities of each series or coupons, by receiving
and holding the same, agrees with the Company and the Trustee for the Securities
of such series that neither the Company nor such Trustee, nor any agent of
either of them shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Holders of the Securities of
such series in accordance with Section 702(b), regardless of the source from
which such information was derived, and

                                      -55-
<PAGE>

that the Trustee shall not be held accountable by reason of mailing any material
pursuant to a request made under Section 702(b).

Section 703.  Reports by Trustee.

       (a)  Within 60 days after March 15 of each year, the Trustee for the
Securities of each series shall mail to each Holder of the Securities of such
series entitled to receive reports pursuant to Section 704(3), a brief report
dated as of such date that complies with Section 313(a) of the Trust Indenture
Act. The Trustee for the Securities of each series shall also comply with
Sections 313(b), 313(c) and 313(d) of the Trust Indenture Act.

       (b)  At the time that the Trustee for the Securities of each series mails
such a report to the Holders of Securities of such series, each such Trustee
shall file a copy of that report with the Commission and with each stock
exchange on which the Securities of that series are listed. The Company shall
provide notice to the appropriate Trustee when the Securities of any series are
listed on any stock exchange.

Section 704.  Reports by Company.

     The Company will:

           (1)  file with the Trustee for the Securities of such series, 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 said Sections, then it will file with such 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 national securities exchange as may be
     prescribed from time to time in such rules and regulations;

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

           (3)  transmit by mail to all Holders of Securities of each series, as
     provided in Section 703(a), within 30 days after the filing thereof with
     the Trustee for the Securities of such series, such summaries of any
     information, documents and reports required to be filed by the Company
     pursuant to paragraphs (1) and (2) of this Section as may be required by
     rules and regulations prescribed from time to time by the Commission.

     Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee, subject
to Section 601 hereof, is entitled to rely exclusively on Officers'
Certificates).

     the assumption by any such successor of the covenants of the Company herein
     and in the Securities; or

           (2)  to add to the covenants of the Company, for the benefit of the
     Holders of all or any particular series of Securities and any related
     coupons (and, if such covenants are to be for the benefit of fewer than all

     additional Events of Default, such supplemental indenture may provide for a
     particular period of grace after default (which period may be shorter or
     longer than that allowed in the case of other defaults) or may limit the
     remedies available to the Trustee upon such default or may limit the right
     of Holders of a majority in aggregate principal amount of that or those
     series of Securities to which such additional Events of Default apply to
     waive such default; or

     Securities of any series in addition to or in place of any certificated
     Securities and to make all appropriate changes for such purposes; provided,
     however, that any such action shall not adversely affect the interests of
     the Holders of Securities of any series or any related coupons in any
     material respect; or

           (7)  to change or eliminate any of the provisions of this Indenture,
     provided, however, that any such change or elimination shall become
     effective only when there is no Security Outstanding of any series created
     prior to the execution of such supplemental indenture which is entitled to
     the benefit of such provision; or

           (8)  to evidence and provide for the acceptance of appointment
     hereunder of a Trustee other than The Bank of New York as Trustee for a
     series of Securities and to add to or change any of the provisions of this
     Indenture as shall be necessary to provide for or facilitate the

                                      -58-

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

           (10) to add to the conditions, limitations and restrictions on the
     authorized amount, form, terms or purposes of issue, authentication and
     delivery of Securities, as herein set forth, other conditions, limitations
     and restrictions thereafter to be observed; or

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

           (12) to add to or change or eliminate any provisions of this

     reduce the amount payable in accordance with

                                      -59-

     Redemption Date); or reduce or alter the method of computation of any
     amount payable upon redemption, repayment or purchase of any Securities by
     the Issuer (or the time when such redemption, repayment or purchase may be
     made); or

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

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

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

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

Section 1001.  Payment of Principal (and Premium, if any) and Interest, if any.

     The Company agrees, for the benefit of each particular series of
Securities, that it will duly and punctually pay in the currency or currency
unit 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
as provided in Sections 311(b) and 311(d)) the principal of (and premium, if
any) and interest, if any, on that series of Securities in accordance with the
terms of the Securities of such series, any coupons appertaining thereto and
this Indenture.  Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, any interest due on Bearer Securities on or
before Maturity shall be payable only upon presentation and surrender of the
several coupons for such interest installments as are evidenced thereby as they
severally mature.  The interest, if any, due in respect of any temporary or
permanent Global Security, together with any additional amounts payable in
respect thereof, as provided in the terms and conditions of such Security, shall
be payable, subject to the conditions set forth in Section 1009, only upon
presentation of such Security to the Trustee thereof for notation thereon of the
payment of such interest.

Section 1002.  Maintenance of Office or Agency.

     If Securities of a series are issuable only as Registered Securities the
Company will maintain in each Place of Payment for that series an office or
agency where Securities of that series may be presented or surrendered for
payment, an office or agency where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company with respect to 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) an office or agency (which may be the
same office or agency) in a Place of Payment for that series in the United
States 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 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

                                      -61-
<PAGE>

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 the Stock Exchange or any other stock exchange
located outside the United States and such stock exchange shall so require, the
Company will maintain a Paying Agent for the Securities of that series in
Luxembourg or any other required city located outside the United States, as the
case may be, so long as the Securities of that series are listed on such
exchange, and (C) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series located outside the United States an office or
agency where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange 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 for the Securities of that series of
the location, and any change in the location, of any such office or agency. If
at any time the Company shall fail to maintain any such required office or
agency in respect of any series of Securities or shall fail to furnish the
Trustee for the Securities of that series with the address thereof, such
presentations (to the extent permitted by law), and surrenders of Securities of
that series may be made and notices and demands may be made or served at the
Corporate Trust Office of such Trustee, except that Bearer Securities of that
series and the related coupons may be presented and surrendered for payment at
the offices specified in the Security, and the Company hereby appoints the same
as its agent to receive such presentations, surrenders, notices and demands.

     Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal (and premium, if any) or interest, if any,
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.
Payments will not be made in respect of Bearer Securities or coupons
appertaining thereto pursuant to presentation to the Company, or its designated
Paying Agents within the United States.  Notwithstanding the foregoing, payment
of principal of (and premium, if any) and interest, if any, on any Bearer
Security denominated and payable in Dollars will be made at the office of the
Company's Paying Agent in the United States, if, and 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 that purpose
by the Company in accordance with this Indenture is illegal or effectively
precluded by exchange controls or other similar restrictions and the Company has
delivered to the Trustee an Opinion of Counsel to that effect.

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

                                      -62-
<PAGE>

then the Company will maintain with respect to each such series of Securities,
or as so required, a Currency Determination 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 particular series of Securities and any related coupons, it will, on or
before each due date of the principal of (and 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 or currency
unit 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
as provided in Sections 311(b) and 311(d)) sufficient to pay the principal (and
premium, if any) and interest, if any, 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 for the Securities of such series of its action or
failure so to act.

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

     The Company will cause each Paying Agent for any particular series of
Securities other than the Trustee for the Securities of such series to execute
and deliver to such Trustee an instrument in which such Paying Agent shall agree
with such 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) or interest, if any, on Securities of that series in
     trust for the benefit of the Persons entitled thereto until such sums shall
     be paid to such Persons or otherwise disposed of as herein provided;

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

           (3)  at any time during the continuation of any such default, upon
     the written request of such Trustee, forthwith pay to such 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 for the Securities of any
series all sums held in trust by the Company or such Paying Agent, such sums to
be held by such Trustee upon the same trusts as those upon which such sums were
held by the Company or such Paying Agent; and, upon such payment by any Paying
Agent to such Trustee, such Paying Agent shall be released from all further
liability with respect to such money.

Section 1005.  Statements as to Compliance.

     The Company will deliver to the Trustee for each series of Securities,
within 120 days after the end of each fiscal year, a written statement signed by
the principal executive officer, principal financial officer or principal
accounting officer of the Company stating that:

           (1)  a review of the activities of the Company during such year and
     of performance under this Indenture has been made under his supervision;
     and

           (2)  to the best of his knowledge, based on such review, the Company
     is in compliance with all conditions and covenants under this Indenture.

     For purposes of this Section, such compliance shall be determined without
regard to any period of grace or requirement of notice provided under this
Indenture.

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, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any right or franchise if the
Board of Directors of the Company shall determine that the preservation thereof
is no longer necessary or desirable in the conduct of the business of the
Company.

Section 1007.  Limitation on Liens

     The Company shall not, and shall not permit any of its Principal
Subsidiaries to, issue, assume, Incur or guarantee any Indebtedness secured by a
mortgage, pledge, lien or other encumbrance, directly or indirectly, on any of
the Common Stock of a Principal Subsidiary owned by the Company or any of its
Principal Subsidiaries, unless the Company's obligations under the Securities
and, if the Company so elects, any other indebtedness of the Company ranking on
a parity with, or prior to, the Securities, shall be secured equally and ratably
with, or prior to, such secured Indebtedness so long as it is outstanding and is
so secured.

Section 1008.  Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any covenant
or condition set forth in Sections 1004 to 1007, inclusive, if before or after
the time for such compliance the Holders of more than 50% in principal amount of
the Outstanding Securities of each series of Securities affected by the omission
shall, in each case by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such covenant or condition, but no
such waiver shall extend to or affect such covenant 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 for the Securities of
each series with respect to any such covenant or condition shall remain in full
force and effect.

Section 1009.  Payment of Additional Amounts.

     If specified pursuant to Section 301, the provisions of this Section 1009
shall be applicable to Securities of any series.

     The Company will, subject to the exceptions and limitations set forth
below, pay to the Holder of any Security or coupon who is a United States Alien
such additional amounts as may be necessary so that every net payment on such
Security or coupon, after deduction or withholding by the Company or any of its
Paying Agents for or on account of any present or future tax, assessment or
other governmental charge imposed upon or as a result of such payment by the
United States (or any political subdivision or taxing authority thereof or
therein), will not be less than the amount provided in such Security or in such
coupon to be then due and payable.  However, the Company will not be required to
make any payment of additional amounts for or on account of:

     (a)  any tax, assessment or other governmental charge that would not have
been so imposed but for (i) the existence of any present or former connection
between such Holder or the beneficial owner of such Security or coupon (or
between a fiduciary, settler or beneficiary of, or a person holding a power
over, such Holder or such beneficial owner, if such Holder or such beneficial
owner is an estate or trust, or a member or shareholder of such Holder or such
beneficial owner, if such Holder or such beneficial owner is a partnership or
corporation) and the United States, including, without limitation, such Holder
or such beneficial owner (or such fiduciary, settler, beneficiary, person
holding a power, member or shareholder) being or having been a citizen, resident
or treated as a resident thereof or being or having been engaged in trade or
business or present therein or having or having had a permanent establishment
therein, or (ii) such Holder's or such beneficial owner's present or former
status as a personal holding company, foreign personal holding company,
controlled foreign corporation or passive foreign investment company with
respect to the United States or as a corporation that accumulates earnings to
avoid United States federal income tax;

     (b)  any tax, assessment or other governmental charge which would not have
been so imposed but for the presentation by the Holder of such Security or
coupon for payment on a date more than 10 days after the date on which such
payment became due and payable or the date on which payment thereof is duly
provided for, whichever occurs later;

     (c)  any estate, inheritance, gift, sales, transfer, personal property tax
or any similar tax, assessment or other governmental charge;

     (d)  any tax, assessment or other governmental charge required to be
withheld by any Paying Agent from any payment in respect of any Security or
coupon, if such payment can be made without such withholding by at least one
other Paying Agent;

     (e)  any tax, assessment or other governmental charge which is payable
otherwise than by withholding from payments in respect of such Security or
coupon;

     (f)  any tax, assessment or other governmental charge imposed on a Holder
or beneficial owner of a Security or coupon that (i) actually or constructively
owns 10 percent or more of the total combined voting power of all classes of
stock of the Company entitled to vote within the meaning of Section 871(h)(3) of
the Code or that is a controlled foreign corporation related to the Company
through stock ownership or (ii) is a bank described in Section 881(c)(3)(A) of
the Code;

     (g)  any tax, assessment or other governmental charge imposed as a result
of the failure to comply with applicable certification, information,
documentation or other reporting requirements concerning the nationality,
residence, identity or connection with the United States of the Holder or
beneficial owner of a Security or coupon, if such compliance is required by
statute or by regulation of the United States, as a precondition to relief or
exemption from such tax, assessment or other governmental charge;

                                      -65-
<PAGE>

     (h)  any tax, assessment or other governmental charge imposed with respect
to payments on any Registered Security by reason of the failure of the Holder or
beneficial owner to fulfill the statement requirement of Sections 871(h) or
881(c) of the Code; or

     (i)  any combination of items (a), (b), (c), (d), (e), (f), (g) and (h);

nor will additional amounts be paid with respect to any payment on any such
Security or coupon to a Holder who is a fiduciary or partnership or other than
the sole beneficial owner of such payment to the extent such payment would be
required by the laws of the United States (or any political subdivision thereof)
to be included in the income for federal income tax purposes of a beneficiary or
settler with respect to such fiduciary or a member of such partnership or a
beneficial owner who would not have been entitled to payment of the additional
amounts had beneficiary, settler, member or beneficial owner been the Holder of
such Security or coupon.

     The term "United States Alien" means any corporation, partnership,
individual or fiduciary that is, as to the United States, a foreign corporation,
a nonresident alien individual, a nonresident fiduciary of a foreign estate or
trust, or a foreign partnership one or more of the members of which is, as to
the United States, a foreign corporation, a nonresident alien individual or a
nonresident fiduciary of a foreign estate or trust.

     Whenever in this Indenture there is mentioned, in any context, the payment
of the principal of (and premium, if any) and interest, if any, on any Security
or payment with respect to any coupon of any series, such mention shall be
deemed to include mention of the payment of additional amounts provided for in
the terms of such Securities and this Section to the extent that, in such
context, additional amounts are, were or would be payable in respect thereof
pursuant to the provisions of this Section and express mention of the payment of
additional amounts (if applicable) in any provisions hereof shall not be
construed as excluding additional amounts in those provisions hereof where such
express mention is not made.

     If the Securities of a series provide for the payment of additional amounts
as contemplated by Section 301(20), at least 10 days prior to the first Interest
Payment Date with respect to that series of Securities (or if the Securities of
that series will not bear interest prior to maturity, the first day on which a
payment of principal and any premium is made), and at least 10 days prior to
each date of payment of principal (and premium, if any) and interest, if any, if
there has been any change with respect to the matters set forth in the below
mentioned Officers' Certificate, the Company will furnish the Trustee for that
series of Securities and the Company's principal Paying Agent or Paying Agents,
if other than such Trustee, with an Officers' Certificate instructing such
Trustee and such Paying Agent or Paying Agents whether such payment of principal
of (and premium, if any) and interest, if any, on the Securities of that series
shall be made to Holders of Securities of that series or any related coupons who
are United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge referred to above or described in the
Securities of that series.  If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities or coupons and the
Company will pay to the Trustee for such series of Securities or such Paying
Agent such additional amounts as may be required pursuant to the terms
applicable to such series.  The Company covenants to indemnify the Trustee for
such series of Securities and any Paying Agent for, and to hold them harmless
against, any loss, liability or expense reasonably incurred without gross
negligence or bad faith on their part arising out of or in connection with
actions taken or omitted by any of them in reliance on any Officers' Certificate
furnished pursuant to this Section 1009.

Section 1010.  Calculation of Original Issue Discount

     If applicable 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 specific
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.

Section 1011.  Statement by Officers as to Default

     The Company shall deliver to the Trustee, as soon as possible and in any
event within five days after the Company becomes aware of the occurrence of any
Event of Default or an event which, with notice or the lapse of time or both,
would constitute an Event of Default, an Officers' Certificate setting forth the
details of such Event of Default or event and the action which the Company
proposes to take with respect thereto.

                           Redemption of Securities
                           ------------------------

Section 1101.  Applicability of This Article.

     Redemption of Securities of any series (whether by operation of a sinking
fund or otherwise) as permitted or required by any form of Security issued
pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; provided, however, that if any provision of any such
form of Security shall conflict with any provision of this Article, the
provision of such form of Security shall govern.

Section 1102.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities of any series shall be
evidenced by or pursuant to a Board Resolution.  In case of any redemption at
the election of the Company of less than all of the Securities of any particular
series, the Company shall, at least 60 days prior to the Redemption Date fixed
by the Company (unless a shorter notice shall be satisfactory to the Trustee for
the Securities of such series) notify such Trustee by Company Request of such
Redemption Date and of the principal amount of Securities of that series to be
redeemed and shall deliver to such Trustee such documentation and records as
shall enable such Trustee to select the Securities to be redeemed pursuant to
Section 1103.  In the case of any redemption of Securities of any series 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 for Securities of such series 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 are to be redeemed, the Company may select
the series to be redeemed, and if less than all the Securities of any series are
to be redeemed, the particular Securities of that series to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee for
the Securities of such series, from the Outstanding Securities of that series
not previously called for redemption, by such method as such Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for

                                      -67-
<PAGE>

Securities of that series, or any integral multiple thereof) of the principal
amount of Securities of that series of a denomination larger than the minimum
authorized denomination for Securities of that series pursuant to Section 302 in
the currency or currency unit in which the Securities of such series are
denominated.

     The Trustee for the Securities of any series to be redeemed shall promptly
notify the Company in writing of the Securities of such series 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 Securities which has been or is to be redeemed.

Section 1104.  Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 106
not later than the thirtieth (30th) day and not earlier than the sixtieth (60th)
day prior to the Redemption Date, to each Holder of Securities to be redeemed.

     All notices of redemption shall state:

             (1)  the Redemption Date,

             (2)  the Redemption Price,

             (3)  if less than all Outstanding Securities of a particular series
     are to be redeemed, the identification (and, in the case of partial
     redemption, the respective principal amounts) of the particular Securities
     to be redeemed, including the Identifying Number of such Securities,

             (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 will become
     due and payable upon each such Security or portion thereof, and that
     interest thereon, if any (or in the case of OID Securities, original issue
     discount), shall cease to accrue on and after said date,

             (6)  the place or places 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,

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

             (8)  that, unless otherwise specified in such notice, Bearer
     Securities of any series, if any, surrendered for redemption must be
     accompanied by all coupons maturing subsequent to the date fixed for
     redemption or the amount of any such missing coupon or coupons will be
     deducted from the Redemption Price or security or indemnity satisfactory to
     the Company, the Trustee for such series and any Paying Agent is furnished,
     and

                                      -68-
<PAGE>

             (9)  if Bearer Securities of any series are to be redeemed and any
     Registered Securities of such series are not to be redeemed, and if such
     Bearer Securities may be exchanged for Registered Securities not subject to
     redemption on this Redemption Date pursuant to Section 305 or otherwise,
     the last date, as determined by the Company, on which such exchanges may be
     made.

     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 for such Securities in the name and at the expense of the Company.

Section 1105.  Deposit of Redemption Price.

     Prior to the opening of business on any Redemption Date, the Company shall
deposit with the Trustee for the Securities to be redeemed or with a Paying
Agent for such Securities (or, if the Company is acting as its own Paying Agent
for such Securities, segregate and hold in trust as provided in Section 1003) an
amount of money in the currency or currency unit 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 as provided in Sections 311(b) and
311(d)) sufficient to pay the principal amount of (and premium, if any,
thereon), and (except if the Redemption Date shall be an Interest Payment Date)
any accrued interest on, all the Securities which are to be redeemed on that
date.

Section 1106.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified in the currency or currency unit in which the
Securities of such series are payable (except as otherwise provided pursuant to
Section 301 for the Securities of such series and except as provided in Sections
311(b) and 311(d)) and from and after such date (unless the Company shall
default in the payment of the Redemption Price) such Securities shall 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 such Security for redemption in accordance with said
notice together with all coupons, if any, appertaining thereto maturing after
the Redemption Date, such Security or specified portions thereof shall be paid
by the Company at the Redemption Price; 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 unless
otherwise specified as contemplated by Section 301, 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 coupons appertaining thereto 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 if there is furnished to the
Company, the Trustee for such Security and any Paying Agent such security or
indemnity as they may require to save the Company, such Trustee and any Paying
Agent harmless.  If thereafter the Holder of such Security shall surrender to
such Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that interest
represented by coupons shall be payable

                                      -69-
<PAGE>

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 thereof (and premium, if any, thereon)
shall, until paid, bear interest from the Redemption Date at a rate per annum
equal to the rate borne by the Security (or, in the case of (i) OID Securities,
the Security's Yield to Maturity or (ii) Indexed Securities, the rate determined
in accordance with the specified terms of those Securities).

Section 1107.  Securities Redeemed in Part.

     Any Registered Security which is to be redeemed only in part shall be
surrendered at the Place of Payment (with, if the Company or the Trustee for
such Security so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company, and the Security Registrar for
such Security duly executed by, the Holder thereof or his attorney duly
authorized in writing), and the Company shall execute and such Trustee shall
authenticate and deliver to the Holder of such Security without service charge,
a new Registered Security or Securities, of any authorized denomination as
requested by such Holder, of the same series and having the same terms and
provisions and in an aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Registered Security so surrendered.

Section 1108.   Tax Redemption; Special Tax Redemption.

        (a)  If specified pursuant to Section 301, Securities of any series may
be redeemed at the option of the Company in whole, but not in part, on not more
than 60 days' and not less than 30 days' notice, on any Redemption Date at the
Redemption Price specified pursuant to Section 301, if the Company determines
that (A) as a result of any change in or amendment to the laws (or any
regulations or rulings promulgated thereunder) of the United States or of any
political subdivision or taxing authority thereof or therein affecting taxation,
or any change in official position regarding application or interpretation of
such laws, regulations or rulings (including a holding by a court of competent
jurisdiction in the United States), which change or amendment is announced or
becomes effective on or after a date specified in Section 301 with respect to
any Security of such series, the Company has or will become obligated to pay
additional amounts pursuant to Section 1009 with respect to any Security of such
series or (B) on or after a date specified in Section 301 with respect to any
Security of such series, any action has been taken by any taxing authority of,
or any decision has been rendered by a court of competent jurisdiction in, the
United States or any political subdivision or taxing authority thereof or
therein, including any of those actions specified in (A) above, whether or not
such action was taken or decision was rendered with respect to the Company, or
any change, amendment, application or interpretation shall be officially
proposed, which, in any such case, in the Opinion of Counsel to the Company will
result in a material probability that the Company will become obligated to pay
additional amounts pursuant to Section 1009 with respect to any Security of such
series, and (C) in any such case specified in (A) or (B) above the Company, in
its business judgment, determines that such obligation cannot be avoided by the
use of reasonable measures available to the Company.

        (b)  Unless otherwise specified pursuant to Section 301, if the Company
shall determine that any payment made outside the United States by the Company
or any of their Paying Agents of principal or interest due in respect of any
Bearer Security (an "Affected Security") of such series or any coupon
appertaining thereto would, under any present or future laws or regulations of
the United States, be subject to any certification, information or other
reporting requirement of any kind, the effect of which requirement is the
disclosure to the Company, any Paying Agent or any governmental authority of the

                                      -70-
<PAGE>

nationality, residence or identity (as distinguished from, for example, status
as a United States Alien) of a beneficial owner of such Affected Security of
such series or coupon that is a United States Alien (other than such a
requirement that (i) would not be applicable to a payment made by the Company,
or any one of their Paying Agents (A) directly to the beneficial owner or (B) to
a custodian, nominee or other agent of the beneficial owner, (ii) can be
satisfied by such custodian, nominee or other agent certifying to the effect
that such beneficial owner is a United States Alien; provided that, in each case
referred to in clauses (i)(B) or (ii), payment by such custodian, nominee or
other agent to such beneficial owner is not otherwise subject to any such
requirement (other than a requirement which is imposed on a custodian, nominee
or other agent described in item (iv) of this sentence), (iii) would not be
applicable to a payment made by at least one other Paying Agent of the Company
or (iv) is applicable to a payment to a custodian, nominee or other agent of the
beneficial owner of such Security who is a United States person (as hereinafter
defined), a controlled foreign corporation for United States tax purposes, a
foreign person 50 percent or more of the gross income of which for the three-
year period ending with the close of its taxable year preceding the year of
payment is effectively connected with a United States trade or business, or is
otherwise related to the United States), the Company shall elect by notice to
the Trustee for such series of Securities either (x) to redeem the Affected
Securities of such series, as a whole, at a redemption price equal to the
principal amount thereof, together with interest accrued to the date fixed for
redemption, or (y) if the conditions of the next succeeding paragraph are
satisfied, to pay the additional amounts specified in such paragraph. The
Company shall make such determination and election as soon as practicable and
give prompt notice thereof (the "Determination Notice") in the manner described
in Section 106 stating the effective date of such certification, information or
reporting requirement, whether the Company has elected to redeem the Affected
Securities of such series or to pay the additional amounts specified in the next
succeeding paragraph, and (if applicable) the last date by which the redemption
of the Affected Securities of such series must take place, as provided in the
next succeeding sentence. If the Company elects to redeem the Affected
Securities of such series, such redemption shall take place on such date, not
later than one year after the giving of the Determination Notice, as the Company
shall specify by notice to such Trustee given not less than 45 nor more than 75
days before the Redemption Date. Notice of such redemption of the Affected
Securities of such series shall be given to the Holders thereof not less than 30
days nor more than 60 days prior to the Redemption Date. Notwithstanding the
foregoing, the Company shall not so redeem the Affected Securities of such
series if the Company shall subsequently determine by notice to the Trustee, not
less than 30 days prior to the Redemption Date, that subsequent payments on the
Affected Securities of such series would not be subject to any such
certification, information or other reporting requirement, in which case the
Company shall give prompt notice of such subsequent determination in the manner
specified in Section 106 and any earlier redemption notice shall be revoked and
be of no further effect. The right of the Holders of Affected Securities called
for redemption to exchange such Affected Securities for Registered Securities
(which Registered Securities will remain Outstanding following such redemption)
will terminate on the fifteenth day prior to the Redemption Date, and no further
exchanges of Affected Securities for Registered Securities shall be permitted
unless the Company shall have made the subsequent determination and given the
notice referred to in the preceding sentence. As used hereinabove, "United
States person" means any citizen or resident of the United States, any
corporation, partnership or other entity created or organized in or under the
laws of the United States and any estate or trust the income of which is subject
to United States federal income taxation regardless of its source.

     If and so long as the certification, information or other reporting
requirement referred to in the preceding paragraph would be fully satisfied by
payment of a withholding tax, backup withholding tax or similar charge, the
Company may elect by notice to the Trustee to pay such additional amounts as may
be necessary so that every net payment made outside the United States following
the effective date of such requirement by the Company or any of their Paying
Agents of principal (or premium, if any) or interest, if any, due in respect of
any Affected Security of such series or any coupon appertaining thereto to a
Holder who certifies that the beneficial owner is a United States Alien (but
without any requirement that the

                                      -71-
<PAGE>

nationality, residence or identity of such beneficial owner be disclosed to the
Company, any Paying Agent or any governmental authority), after deduction or
withholding for or on account of such withholding tax, backup withholding tax or
similar charge (other than a withholding tax, backup withholding tax or similar
charge that (i) is the result of a certification, information or other reporting
requirement described in the third parenthetical clause of the first sentence of
the preceding paragraph or (ii) is imposed as a result of presentation of any
such Affected Security or such coupon for payment more than 10 days after the
date on which such payment becomes due and payable or on which payment thereof
was duly provided for, whichever occurs later), will not be less than the amount
provided in such Affected Security or such coupon to be then due and payable. In
the event the Company elects to pay such additional amounts, (the Company's
election to exercise such right to be evidenced by prompt notice to the Trustee
for the Securities of the appropriate series), the Company will have the right,
at its sole option, at any time, to redeem the Affected Securities of such
series as a whole, but not in part, at the Redemption Price, subject to the
provisions of the last four sentences of the immediately preceding paragraph. If
the Company has made the determination described in the preceding paragraph with
respect to certification, information or other reporting requirements applicable
only to interest and subsequently makes a determination in the manner and of the
nature referred to in such preceding paragraph with respect to such requirements
applicable to principal, the Company will redeem the Affected Securities of such
series in the manner and on the terms described in the preceding paragraph
unless the Company elects to have the provisions of this paragraph apply rather
than the provisions of the immediately preceding paragraph. If in such
circumstances the Affected Securities of such series are to be redeemed, the
Company shall have no obligation to pay additional amounts pursuant to this
paragraph with respect to principal (or premium, if any) or interest accrued and
unpaid after the date of the notice of such determination indicating such
redemption, but will be obligated to pay such additional amounts with respect to
interest accrued and unpaid to the date of such determination. If the Company
elects to pay additional amounts pursuant to this paragraph and the condition
specified in the first sentence of this paragraph should no longer be satisfied,
then the Company shall promptly redeem the Affected Securities of such series in
whole, but not in part, at the Redemption Price subject to the provisions of the
last four sentences of the immediately preceding paragraph. If the Company
elects to, or is required to, redeem the Affected Securities of such series
pursuant to this paragraph, it shall publish in the manner and to the extent
provided in Section 106 prompt notice thereof. If the Affected Securities of
such series are to be redeemed pursuant to this paragraph, the redemption shall
take place on such date, not later than one year after publication of the notice
of redemption, as the Company shall specify by notice to the Trustee for such
series of Securities at least 60 days prior to the Redemption Date. Any
redemption payments made by the Company pursuant to this paragraph shall be
subject to the continuing obligation of the Company to pay additional amounts
pursuant to this paragraph.

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

Section 1201.  Applicability of This Article.

     Redemption of Securities through operation of a sinking fund as permitted
or required by any form of Security issued pursuant to this Indenture shall be
made in accordance with such form of Security and this Article; provided,
however, that if any provision of any such form of Security shall conflict with
any provision of this Article, the provision of such form of Security shall
govern.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any particular 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 particular series is herein referred

                                      -72-
<PAGE>

to as an "optional sinking fund payment". If provided for by the terms of
Securities of any particular series, the cash amount of any sinking fund payment
may be subject to reduction as provided in Section 1202. Each sinking fund
payment shall be applied to the redemption of Securities of any particular
series as provided for by the terms of Securities of that series.

Section 1202.  Satisfaction of Sinking Fund Payments With Securities.

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

Section 1203.  Redemption of Securities for Sinking Fund.

     Not less than 60 days prior to each sinking fund payment date for any
particular series of Securities, the Company will deliver to the Trustee for the
Securities of such series an Officers' Certificate specifying the amount of the
next ensuing mandatory sinking fund payment for that series pursuant to the
terms of that series, the portion thereof, if any, which is to be satisfied by
payment of cash in the currency or currency unit in which the Securities of that
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of that series and except as provided in Sections 311(b) and
311(d)) and the portion thereof, if any, which is to be satisfied by delivering
and crediting Securities of that series pursuant to Section 1202 and shall state
the basis for such credit and that such Securities have not previously been so
credited and will also deliver to such Trustee any Securities to be so
delivered.  Such 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.

                       Meetings of Holders of Securities
                       ---------------------------------

Section 1301.  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.

Section 1302.  Call, Notice and Place of Meetings.

        (a)  The Trustee for any series of Securities that includes Bearer
Securities, may at any time call a meeting of the Holders of Securities of such
series for any purpose specified in Section 1301, to be held at

                                      -73-
<PAGE>

such time and at such place in the Borough of Manhattan, The City of New York,
or in London, as such Trustee shall determine. Notice of every meeting of
Holders of Securities of such 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 in Section 106, not less than 20
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 such series shall have requested the Trustee for any such series to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1301, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and such Trustee shall not have made the
first publication of the notice of such meeting within 30 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 Borough of Manhattan, 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 subsection (a) of this Section.

Section 1303.  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 for
a Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders.  The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons
entitled to vote at such meeting and their counsel, any representatives of the
Trustee for such series and its counsel and any representatives of the Company
and its counsel.

Section 1304.  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.  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.  Subject to Section 1305(d), notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1302(a), except that
such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened.  Notice of the reconvening of
an adjourned meeting shall state expressly that Persons entitled to vote a
majority in principal amount of the Outstanding Securities of such series shall
constitute a quorum.

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

                                      -74-
<PAGE>

affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Securities of that series.

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

Section 1305.  Determination of Voting Rights; Conduct and Adjournment of
Meetings.

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

        (b)  The Trustee for any series of Securities that includes Bearer
Securities 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 1302(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 Securities of
such series held or represented by him as determined in accordance with Section
115; 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 1302 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 1306.  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 triplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each

                                      -75-
<PAGE>

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 1302 and, if applicable, Section 1304. 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 for such series of Securities to be preserved by such Trustee, the
latter to have attached thereto the ballots voted at the meeting. Any record so
signed and verified shall be conclusive evidence of the matters therein stated.

                                  *    *    *

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