agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
is or are delivered to the Trustee, and, where it is hereby expressly required,
to the Company. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Holders signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 6.1) conclusive in favor of

such execution is by a Person acting in other than his individual capacity, 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 deems sufficient and in
accordance with such reasonable rules as the Trustee may determine.

               (d) The ownership of Debentures shall be proved by the Securities
Register.

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

               (f) The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to take any action
under this Indenture by vote or consent. If a record date is fixed, those
Persons who

                                      18
<PAGE>

were Holders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled 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.

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

          Section 1.5    Notices, Etc. to Trustee and Company.  Any request,
                         ------------------------------------

other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with

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

               (b) the Company by the Trustee or by any Holder shall be
sufficient for every purpose (except as otherwise provided in Section 5.1
hereof) hereunder if in writing and mailed, first class, postage prepaid, to the
Company addressed 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 the Trustee by the Company.

          Section 1.6    Notice to Holders; Waiver.  Where this Indenture
                         -------------------------
provides for notice to Holders of any event, such notice shall be sufficiently
given (unless otherwise herein expressly provided) if in writing and mailed,
first class postage prepaid, to each Holder affected by such event, at the
address of such Holder as it appears in the Securities Register on the date such
notice is mailed, which shall be not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice.  In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders.  Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice.  Waivers of

                                      19
<PAGE>

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

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

          Section 1.7    Conflict with Trust Indenture Act.  If any provision of
                         ---------------------------------
this Indenture limits, qualifies or conflicts with a provision of the Trust
Indenture Act that is required under such act to be a part of and govern this
Indenture, the latter provision shall control.  If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the former provision shall be deemed to apply.

          Section 1.8    Effect of Headings and Table of Contents.  The Article

validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

or other payment in respect of any such delay) with the same force and effect as

                         ----------------------------
a duly authorized issue of Debentures of the Company (herein called the
"Debentures") limited to the aggregate principal amount of $______________,
issued under an Indenture, dated as of _____ __, 20__ (herein called the
"Indenture"), between the Company and Chase Manhattan Trust Company, National
Association, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Trustee,
the Company and the Holders of the Debentures, and of the terms upon which the
Debentures are, and are to be, authenticated and delivered. All terms used in
this Debenture that are defined in the Indenture shall have the meanings
assigned to them in the Indenture.

          The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  For periods less than a full
month, interest shall be computed on the actual number of elapsed days based on
a 360-day year.  In the event that any date on which interest is payable on this
Debenture is not a Business Day, then a payment of the interest on such date
will be made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay) with the same force and
effect as if made on the date the payment was originally payable.  A "Business
Day" shall mean any day other than a Saturday or a Sunday or a day on which
banking institutions in the

City of New York are authorized or required by law or executive order to remain
closed or a day on which the Corporate Trust Office of the Trustee[, or the
principal office of the Property Trustee under the Trust Agreement] is closed
for business. The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Debenture (or one or more Predecessor
Debentures, as defined in the Indenture) is registered at the close of business
on the Regular Record Date, for such interest installment which shall be the
date which is the fifteenth day (whether or not a Business Day) next preceding
such Interest Payment Date. Any such interest installment not so punctually paid
or duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Debenture (or one or more Predecessor Debentures) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Debentures
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Debentures may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

          The Company shall have the right at any time during the term of this
Debenture, from time to time, to extend the interest payment period of such
Debenture for up to [20 consecutive quarters] with respect to each deferral
period (each such deferral period an "Extension Period"), during which periods
the Company shall have the right not to make payments of interest on any
Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest, if any,
thereon to the extent permitted by applicable law); provided that during any
such Extension Period, the Company shall not (a) declare or pay any dividend on,
make distributions with respect to, or redeem, purchase or make a liquidation
payment with respect to, any of its Common Stock (other than (i) purchases or
acquisitions of shares of Common Stock in connection with the satisfaction by
the Company of its obligations under any employee benefit plan, (ii) as a result
of a reclassification of the Company's Common Stock or the exchange or
conversion of one class or series of the Company's Common Stock for another
class or series of the Company's Common Stock, (iii) the purchase of fractional

exchange provisions of such Common Stock of the Company or the security being
converted or exchanged or (iv) purchases or acquisitions of shares of Common
Stock to be used in connection with acquisitions of Common Stock by

guarantee payments with respect to the foregoing and (b) the Company shall not
make any payment of principal or premium, if any, on or repurchase any debt
securities (including guarantees) other than at stated maturity issued by the
Company which rank pari passu with or junior to the Debentures. Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that no Extension Period shall exceed [20
consecutive quarters] or extend beyond the Stated Maturity of the Debenture.
Upon the termination of any such Extension Period and upon the payment of all
accrued and unpaid interest and any Additional Interest then due, the Company
may elect to begin a new Extension Period, subject to the above requirements. No
interest shall be due and payable during an Extension Period except at the end
thereof. The Company shall give the Trustee, [the Property Trustee and the
Administrative Trustees (as defined in the Trust Agreement)] notice of its
selection of an Extension Period at least one Business Day prior to [the earlier

Securities (or if no Preferred Securities are outstanding, for] the date
interest on the Debentures) would have been payable except for the election to
begin such Extension Period and (ii) the date [the Property Trustee (or if no
Preferred Securities are outstanding,] the Debenture Trustee) is required to
give notice to the NYSE or other applicable self-regulatory organizations [or to
holders of [such Preferred Securities (or, if no Preferred Securities are
outstanding, to the holders of] such Debentures) of the record date.

Debenture will be made [if a Global Security is issued - to The Depository
Trust Company or its nominee] [if securities in definitive form are issued - at
the office or agency of the Paying Agent maintained for that purpose in the
United States], in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts
provided, however, that at the option of the Company payment of interest may be
made (i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Securities Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Securities
Register.

          The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and subject in right of payments to the
prior payment in full of all Senior Debt (as defined in the Indenture), and this
Debenture is issued subject to the provisions of the Indenture with respect
thereto.  Each Holder of this Debenture, by accepting the same, (a) agrees to
and shall be bound by such provisions, (b) authorizes and directs the Trustee on
his behalf to take such actions as

                                      25
<PAGE>

may be necessary or appropriate to effectuate the subordination so provided and
(c) appoints the Trustee his attorney-in-fact for any and all such purposes.
Each Holder hereof, by his acceptance hereof, waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Debt, whether now outstanding or hereafter incurred,
and waives reliance by each such holder upon said provisions.

          At any time on or after _________, 20__, the Company may, at its
option, subject to the terms and conditions of Article 11 of the Indenture,

          In the event of redemption of this Debenture in part only, a new
Debenture or Debentures for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

          [If a Special Event shall occur and be continuing, this Debenture
shall be exchangeable for Preferred Securities in accordance with Section 11.9
of the Indenture or, in certain circumstances, redeemable by the Company in
accordance with Section 11.8 of the Indenture.]

         [Subject to the terms and conditions set forth in Article 13 of the
Indenture, this Debenture is convertible, at the option of the Holder hereof,
into shares of Common Stock.]

          If an Event of Default shall occur and be continuing, the principal of
the Debentures may be declared due and payable in the manner, with the effect
and subject to the conditions provided in the Indenture.

          The Indenture contains provisions for satisfaction, discharge and
defeasance of the entire indebtedness of this Debenture upon compliance by the

Holders of a majority in principal amount of the Debentures.  The Indenture also
contains provisions permitting Holders of specified percentages in principal
amount

                                      26
<PAGE>

of the Debentures at the time Outstanding, on behalf of the Holders of all
Debentures, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver shall be conclusive and binding upon the Holder of
this Debenture and upon all future Holders of this Debenture and of any
Debenture issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Debenture.

          As provided in and subject to the provisions of the Indenture, if an
Event of Default occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures may declare the principal amount of all the Debentures to
be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders); [provided that, if upon an Event of Default,
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures fail to declare the principal of all the Debentures to be
immediately due and payable, the holders of at least 25% in aggregate
liquidation amount of the Preferred Securities then out standing shall have such
right by a notice in writing to the Company and the Trustee,] and upon any such
declaration such principal amount (or specified amount) of and the accrued
interest (including any Additional Interest) on all the Debentures shall become
immediately due and payable, provided that the payment of principal and interest
(including any Additional Interest) on such Debentures shall remain subordinated
to the extent provided in Article 12 of the Indenture.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Debenture is registrable in the
Securities Register, upon surrender of this Debenture for registration of
transfer at the Company Office duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Securities
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Debentures, of authorized denominations
and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.  No service charge shall be made for any such
registration of transfer or exchange, but the Company may require

                                      27
<PAGE>

payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

          Prior to due presentment of this Debenture for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debenture is registered as the owner
hereof for all purposes, whether or not this Debenture be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

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

          The Company and, by its acceptance of this Debenture or a beneficial
interest therein, the Holder of, and any Person that acquires a beneficial
interest in, this Debenture agree that for United States Federal, state and
local tax purposes it is intended that this Debenture constitute indebtedness.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF
LAW PRINCIPLES THEREOF.

form without coupons and shall be issuable in denominations of [$1,000] and any
integral multiple thereof.

          Section 3.3  Execution, Authentication, Delivery and Dating.  The
                       ----------------------------------------------
Debentures shall be executed on behalf of the Company by a duly authorized
officer on behalf of the Company, whose signature shall be certified by the
Company's Secretary or one of its Assistant Secretaries.  The signature of any
of these officers on the Debentures may be manual or facsimile.

          Debentures bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Debentures or did not
hold such offices at the date of such Debentures.  Upon the execution and
delivery of this Indenture, or from time to time thereafter, Debentures may be
executed by the Company and delivered to the Trustee for authentication, and the
Trustee shall thereupon authenticate and make available for delivery said
Debentures upon Company Order without any further action by the Company.
Debentures may be

                                      32
<PAGE>

authenticated on original issuance from time to time and delivered pursuant to
such procedures acceptable to the Trustee ("Procedures") as may be specified
from time to time by Company Order. Procedures may authorize authentication and
delivery pursuant to oral instructions of the Company or a duly authorized
agent, which instructions shall be promptly confirmed in writing.

          Each Debenture shall be dated the date of its authentication.

          No Debenture shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose, unless there appears on such Debenture a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
officers, and such certificate upon any Debenture shall be conclusive evidence,
and the only evidence, that such Debenture has been duly authenticated and
delivered hereunder.

          Section 3.4  Temporary Debentures.  Pending the preparation of
                       --------------------
definitive Debentures, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Debentures which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Debentures in lieu
of which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Debentures may
determine, as evidenced by their execution of such Debentures.

          If temporary Debentures are issued, the Company will cause
definitive Debentures to be prepared without unreasonable delay. After the
preparation of definitive Debentures, the temporary Debentures shall be
exchangeable for definitive Debentures upon surrender of the temporary
Debentures at the office or agency of the Company designated for the purpose
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Debentures, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like aggregate principal amount
of definitive Debentures of authorized denominations. Until so exchanged, the
temporary Debentures shall in all respects be entitled to the same benefits
under this Indenture as definitive Debentures.

          Section 3.5  Registration, Transfer and Exchange.  The Company shall
                       -----------------------------------
cause to be kept at the Corporate Trust Office of the Trustee a register in
which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Debentures and of transfers of Debentures.
Such register is

                                      33
<PAGE>

herein sometimes referred to as the "Securities Register." The Trustee is hereby
appointed "Securities Registrar" for the purpose of registering Debentures and
transfers of Debentures as herein provided.

          Upon surrender for registration of transfer of any Debenture at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Debentures of any
authorized denominations, of a like aggregate principal amount.

          At the option of the Holder, Debentures may be exchanged for other
Debentures of any authorized denominations, of a like aggregate principal
amount, upon surrender of the Debentures to be exchanged at such office or
agency.  Whenever any Debentures are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Debentures
which the Holder making the exchange is entitled to receive.

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

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

          No service charge shall be made to a Holder for any transfer or
exchange of Debentures, 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 transfer or exchange of Debentures.

          Notwithstanding any of the foregoing, any Global Security shall be
exchangeable pursuant to this Section 3.5 for Debentures registered in the names
of Persons other than the Depositary for such Debenture or its nominee only if
(a) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for any Global Security and the Company shall not have
appointed a successor depositary within 90 days after such notice, or if at any
time such Depositary ceases

                                      34
<PAGE>

to be a clearing agency registered under the Securities Exchange Act of 1934, as
amended, (b) the Company executes and delivers to the Trustee a Company Order
that any Global Security shall be so exchangeable or (c) there shall have
occurred and be continuing an Event of Default. Any Global Security shall be
exchangeable for Debentures registered in such names as such Depositary shall
direct.

          Notwithstanding any other provisions in this Indenture, a Global
Security may not be transferred except as a whole by the Depositary with respect
to a Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.

          Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, register the transfer of or exchange
any Debenture during a period beginning at the opening of business 15 days
before the day of selection for redemption of Debentures pursuant to Article 11
and ending at the close of business on the day of mailing of notice of
redemption or (b) to register the transfer of or exchange any Debenture so
selected for redemption in whole or in part, except, in the case of any
Debenture to be redeemed in part, any portion thereof not to be redeemed.

          Section 3.6  Mutilated, Destroyed, Lost and Stolen Debentures.  If any
                       ------------------------------------------------
mutilated Debenture is surrendered to the Trustee together with such security or
indemnity as may be required by the Company or the Trustee to save each of them
harmless, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Debenture and bearing a number not
contemporaneously outstanding.

          If there shall be delivered to the Company and to the Trustee (a)
evidence to their satisfaction of the destruction, loss or theft of any
Debenture, and (b) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of actual notice to the Company or
the Trustee that such Debenture has been acquired by a bona fide purchaser, the
Company shall execute and upon a Company Order the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Debenture, a new
Debenture bearing a number not contemporaneously outstanding.

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

                                      35
<PAGE>

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

          Every new Debenture issued pursuant to this Section in lieu of any
destroyed, lost or stolen Debenture shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Debenture shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Debentures 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 Debentures.

          Section 3.7  Payment of Interest; Interest Rights Preserved.  Interest
                       ----------------------------------------------
on any Debenture which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date, shall be paid to the Person in whose name that
Debenture (or one or more Predecessor Debentures) is registered at the close of
business on the Regular Record Date, except that interest payable on the Stated
Maturity of the Debentures shall be paid to the Person to whom principal is
paid.

          Any interest on the Debentures which is payable, but is not timely
paid or duly provided for, on an Interest Payment Date (herein called "Defaulted
Interest"), shall forthwith cease to be payable to the registered Holder on the
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 (a) or (b) below:

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

the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be mailed, first class, postage prepaid,
to each Holder of the Debentures at the address of such Holder as it appears in
the Securities 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 Debentures (or their respective
Predecessor Debentures) are registered on such Special Record Date and shall no
longer be payable pursuant to the following clause (b).

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

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

than the Trustee, be delivered to the Trustee, and any such Debentures and
Debentures surrendered directly to the Trustee for any such purpose shall be
promptly canceled by it. The Company may at any time deliver or cause to be
delivered to the Trustee for cancellation any Debentures previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Debentures so delivered shall be promptly canceled by
the Trustee. No Debentures shall be authenticated in lieu of or in exchange for
any Debentures canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Debentures shall be destroyed by the
Trustee and upon request, the Trustee shall deliver to the Company a certificate

                        -----------------------------------
have the right, at any time during the term of the Debentures, from time to time
to extend the interest payment period for the Debentures for up to [20
consecutive quarters] with respect to each deferral period (each, an "Extension
Period") during which periods the Company shall have the right to not make
payments of interest on any Interest Payment Date, and at the end of such
Extension Period the Company shall pay all interest then accrued and unpaid
thereon (together with Additional Interest thereon, if any, at the rate
specified for the Debentures to the extent permitted by applicable law),
provided, however, that during any such Extension Period, the Company shall not
(a) declare or pay any dividend on, make distributions with respect to, or
redeem, purchase or make a liquidation payment with respect to, any of its
Common Stock (other than (i) purchases or acquisitions of shares of Common Stock
in connection with the satisfaction by the Company of its obligations under any
employee benefit plan, (ii) as a result of a reclassification of the Company's
Common Stock or the exchange or conversion of one class or series of the
Company's Common Stock for another class or series of the Company's Common
Stock, (iii) the purchase of fractional interests in shares of the Company's
Common Stock pursuant to the conversion or exchange provisions of such Common
Stock of the Company or the security being converted or exchanged or (iv)
purchases or acquisitions of shares of Common Stock to be used in connection

dividend reinvestment plan) or make any guarantee payments with respect to the
foregoing and (b) the Company shall not make any payment of principal or
premium, if any, on or repurchase any debt securities (including guarantees)

or junior to the Debentures. Prior to the termination of any such Extension
Period, the Company may further extend the interest payment period, provided
that no Extension Period shall exceed [20 consecutive quarters] or extend beyond
the Stated Maturity of the Debentures. Upon the termination of any such
Extension Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due, the Company may elect to begin a new Extension
Period, subject to the above requirements. No interest shall be due and payable
during an Extension Period except at the end thereof. The Company shall give the
Trustee[, the Property Trustee and the Administrative Trustees (as defined in
the Trust Agreement)] notice of its selection of an Extension Period at least
one Business Day prior to the earlier of (i) the record date for the date [the
distributions on the Preferred Securities (or if no Preferred Securities are
outstanding, for the date] interest on the Debentures[)] would have been payable
except for the election to begin such Extension Period and (ii) the date the
[Property Trustee (or if no Preferred Securities are outstanding, the Debenture]
Trustee[)] is required to give notice to the NYSE or other applicable self-
regulatory organizations or[ to holders of such Preferred Securities (or, if no
Preferred Securities are outstanding,] to the holders of such Debentures[)] of
the record date. Such notice shall specify the period selected.

          The Company, or the Trustee at the request of the Company, shall
promptly give notice of the Company's selection of such Extension Period to the
Holders of the outstanding Debentures.

          Section 3.12  Right of Set-off.  Notwithstanding anything to the

contrary in the Indenture, the Company shall have the right to set-off any
payment it is otherwise required to make thereunder in respect of the Debentures
to the extent the Company has theretofore made, or is concurrently on the date
of such payment making, a payment relating to the Debentures under the
Guarantee.

          Section 3.13  Agreed Tax Treatment.  Each Debenture issued hereunder
                        --------------------
shall provide that the Company and, by its acceptance of a Debenture or a
beneficial interest therein, the Holder of, and any Person that acquires a
beneficial interest in, such Debenture agree that for United States Federal,
state and local tax purposes it is intended that such Debenture constitute
indebtedness.

          Section 3.14  CUSIP Numbers.  The Company in issuing the Debentures
                        -------------
may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee
shall use such "CUSIP" number in notices of redemption as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such number either as printed on the Debentures or as
contained in

                                      39

any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Debentures, and any such redemption shall
not be affected by any defect in or omission of such numbers.

                        ---------------
distribution of Debentures to holders of the Preferred Securities in connection
with the involuntary or voluntary dissolution, winding up or liquidation of the
Trust,

                        (i)  the Debentures in certificated form may be
     presented to the Trustee by the Property Trustee in exchange for one or
     more global certificates in an aggregate principal amount equal to the
     aggregate principal amount of all outstanding Debentures (each a "Global
     Security"), to be registered in the name of the Depositary, or its nominee,
     and delivered by the Trustee to the Depositary, or its custodian, for
     crediting to the accounts of its participants pursuant to the procedures of
     the Depositary. The Company upon any such presentation shall execute a
     Global Security in such aggregate principal amount and deliver the same to
     the Trustee for authentication and delivery in accordance with this
     Indenture; and

                        (ii) if any Preferred Securities are held in non book-
     entry certificated form, the Debentures in certificated form may be
     presented to the Trustee by the Property Trustee and any Preferred Security
     certificate which represents Preferred Securities other than Preferred
     Securities held by the Depositary or its nominee ("Non Book-Entry Preferred
     Securities") will be deemed to represent beneficial interests in Debentures
     presented to the Trustee by the Property Trustee having an aggregate
     principal amount equal to the aggregate liquidation amount of the Non Book-
     Entry Preferred Securities until such Preferred Security certificates are
     presented to the Securities Registrar for registration of transfer or
     reissuance at which time such Non-Book Entry Preferred Security
     certificates will be canceled and a Debenture, registered in the name of
     the holder of the Preferred Security certificate or the transferee of the
     holder of such Preferred Security certificate, as the case may be, with an
     aggregate principal amount equal to the aggregate liquidation amount of the
     Preferred Security certificate canceled, will be executed by the Company
     and delivered to the Trustee for authentication and delivery in accordance
     with this Indenture. On issue of such Debentures, Debentures with an
     equivalent aggregate principal amount that were presented by the Property
     Trustee to the Trustee will be deemed to have been canceled.]

               (b) A Global Security may be transferred, in whole but not in
part, only to another nominee of the Depositary, or to a nominee of such
successor Depositary.

               (c) If (i) the Depositary notifies the Company that it is
unwilling or unable to continue as a depositary for such Global Security and no
successor depositary shall have been appointed within 90 days by the Company,
(ii) the Depositary, at any time, ceases to be a clearing agency registered
under the Exchange Act at which time the Depositary is required to be so
registered to act as such depositary and no successor depositary shall have been
appointed within 90 days by the Company, (iii) the Company, in its sole
discretion, determines that such Global Security shall be so exchangeable or
(iv) there shall have occurred an Event of Default with respect to such
Debentures, as the case may be, the Company will execute, and, subject to
Article 3 of this Indenture, the Trustee, upon written notice from the Company
and receipt of a Company Order, will authenticate and deliver the Debentures in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Security in exchange for such Global Security. In addition, upon an Event of
Default or if the Company may at any time determine that the Debenture shall no
longer be represented by a Global Security, in such event the Company will
execute, and subject to Section 3.5 of this Indenture, the Trustee, upon receipt
of an Officers' Certificate evidencing such determination by the Company and a
Company Order, will authenticate and make available for delivery the Debentures
in definitive registered form without coupons, in authorized denominations, and
in an aggregate principal amount equal to the principal amount of the Global
Security in exchange for such Global Security. Upon the exchange of the Global
Security for such Debentures in definitive registered form without coupons, in
authorized denominations, the Global Security shall be canceled by the Trustee.
Such Debentures in definitive registered form issued in exchange for the Global
Security shall be registered in such names and in such authorized denominations
as the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Debentures to the Depositary for delivery to the Persons in whose names
such Debentures are so registered.

as amended, and (ii) the Holders will not recognize income, gain or loss for
Federal income tax purposes as a result of such covenant defeasance and will be

same times as would have been the case if such covenant defeasance had not
occurred; and

               (e)  the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such covenant defeasance have been

with respect to moneys deposited with it for any payment shall at the expense of
the Company, mail by first class mail to Holders of Debentures at their
addresses as they shall appear on the Securities Register for the Debentures,
notice that such moneys remain and that, after a date specified therein, which
shall not be less than 30 days from the date of such mailing any unclaimed

          Section 5.2  Acceleration of Maturity; Rescission and Annulment.  If
                       --------------------------------------------------
an Event of Default occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures of any series may declare the principal amount of all the
Debentures of such series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders); [provided that,
if upon an Event of Default, the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Debentures fail to declare the principal of
all the Debentures to be immediately due and payable, the holders of at least
25% in aggregate liquidation amount of the Preferred Securities then outstanding
shall have such right by a notice in writing to the Company and the Trustee,]
and upon any such declaration such principal amount (or specified amount) of and
the accrued interest (including any Additional Interest) on all the Debentures
shall become immediately due and payable, provided that the payment of principal
and interest (including any Additional Interest) on the Debentures shall remain
subordinated to the extent provided in Article 12.

                                      47
<PAGE>

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

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

                    (A) all overdue installments of interest (including any
          Additional Interest) on the Debentures;

                    (B) the principal of (and premium, if any, on) the
          Debentures which have become due otherwise than by such declaration of
          acceleration and interest thereon at the rate borne by the Debentures;

                    (C) to the extent that payment of such interest is lawful,
          interest (including any Additional Interest) upon overdue installments
          of interest at the rate borne by the Debentures;

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

               (ii) all Events of Default with respect to Debentures, other
     than the non-payment of the principal of the Debentures which has become
     due solely by such acceleration, have been cured or waived as provided in
     Section 5.13. [If the Holders of a majority in principal amount of the
     Outstanding Debentures fail to rescind and annul such declaration and its
     consequences, the holders of a majority in liquidation amount of the
     Preferred Securities then outstanding shall have such right.]

                       -------------------------------------------------------
Trustee.
-------

          The Company covenants that if:

                                      48
<PAGE>

               (a) default is made in the payment of any installment of interest
(including any Additional Interest) on the Debentures when such interest becomes
due and payable and such default continues for a period of 30 days, or

               (b) default is made in the payment of the principal of (and
premium, if any, on) the Debentures whether at the Stated Maturity thereof or
upon redemption, by declaration or otherwise, the Company will, upon demand of
the Trustee, pay to it, for the benefit of the Holders of the Debentures, the
whole amount then due and payable on the Debentures for principal (and premium,
if any) and interest (including any Additional Interest), including, to the
extent that payment of such interest shall be lawful, interest on any overdue
principal (and premium, if any) and on any overdue installments of interest
(including any Additional Interest) at the rate borne by the Debentures, and, in
addition thereto, all amounts owing the Trustee under Section 6.7.

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

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

          Section 5.4  Trustee May File Proofs of Claim.  In case of the

pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Debentures:

               (a) the Trustee (irrespective of whether the principal of the
Debentures shall then be due and payable as therein expressed or by declaration
or

                                      49
<PAGE>

otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal (and premium, if any) or
interest (including any Additional 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 (and premium, if any) and interest (including any Additional
     Interest) owing and unpaid in respect to the Debentures and to file such
     other papers or documents as may be necessary or advisable and to take any
     and all actions as are authorized under the Trust Indenture Act in order to
     have the claims of the Holders and any predecessor to the Trustee under
     Section 6.7 allowed in any such judicial proceedings; and

                    (ii)  in particular, the Trustee shall be authorized to
     collect and receive any moneys or other property payable or deliverable on
     any such claims and to distribute the same in accordance with Section 5.6;
     and

               (b)  any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7;

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

Debentures.  All rights of action and claims under this Indenture or the
----------
Debentures may be prosecuted and enforced by the Trustee without the possession
of any of the Debentures or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgement
shall, after provision for the payment of

                                      50
<PAGE>

all the amounts owing the Trustee and any predecessor Trustee under Section 6.7,
its agents and counsel, be for the ratable benefit of the Holders of the
Debentures in respect of which such judgement has been recovered.

                       ------------------------------
collected or to be applied by the Trustee with respect to the Debentures
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money or
property on account of principal (or premium, if any) or interest (including any
Additional Interest), upon presentation of the Debentures and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

          FIRST:  To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7;

          SECOND:  To the payment of the amounts then due and unpaid upon the
Debentures for principal (and premium, if any) and interest (including any
Additional Interest), 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 the Debentures for principal (and
premium, if any) and interest (including any Additional Interest), respectively;

          THIRD:  The balance, if any, to the Person or Persons entitled
thereto; and

          FOURTH:  To the Company.

          Section 5.7  Limitation on Suits.  No Holder of the Debentures[,
                       -------------------
including a holder of Preferred Securities acting to enforce the rights of the
Property Trustee as a Holder of the Debentures pursuant to Section 6.8 of the
Trust Agreement,] shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture or for the appointment of a receiver,
assignee, trustee, liquidator, sequestrator (or other similar official) or for
any other remedy hereunder, unless:

               (a) such Holder has previously given written notice to the
Trustee of a continuing Event of Default;

                                      51
<PAGE>

               (b) [if the Trust is not the sole Holder of the Outstanding
Debentures,] the Holders of not less than 25% in principal amount of the
Outstanding Debentures shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

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

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

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

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

          Section 5.8  Unconditional Right of Holders to Receive Principal,
                       ----------------------------------------------------
Premium and Interest.  Notwithstanding any other provision in this Indenture,
--------------------
the Holder of any Debenture shall have the right which is absolute and
unconditional to receive payment of the principal of (and premium, if any) and
(subject to Section 3.7) interest (including any Additional Interest) on such
Debenture on the Maturity [or to convert such Debenture in accordance with
Article 13] and to institute suit for the enforcement of any such payment and
right to convert, and such right shall not be impaired without the consent of
such Holder. [For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Indenture and
the Trust Agreement, upon an Event of Default specified in Sections 5.1(a) or
5.1(b), any holder of Preferred Securities shall have the right to institute a
proceeding directly against the Company, for enforcement of payment to such
holder of the principal amount of or interest on Debentures having a principal
amount equal to the liquidation amount of the Preferred Securities of such
holder (a "Direct Action"). Notwithstanding any payment made to such holder of
Preferred Securities by the Company in connection with a Direct Action, the
Company shall

                                      52
<PAGE>

remain obligated to pay the principal of or interest on the Debentures held by
the Trust or the Property Trustee. In connection with any such Direct Action,
the rights of the Company will be subrogated to the rights of any holder of the
Preferred Securities to the extent of any payment made by the Company to such
holder of Preferred Securities as a result of such Direct Action. Except as set
forth in this Section, the holders of Preferred Securities shall have no right
to execute any right or remedy available to the Holders of or in respect of, the
Debentures.]

          Section 5.9  Restoration of Rights and Remedies.  If the Trustee or
                       ----------------------------------
any Holder has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case the Company, the Trustee and the Holder shall, subject to
any determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

          Section 5.10 Rights and Remedies Cumulative.  Except as otherwise
                       ------------------------------
provided in the last paragraph of Section 3.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and 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 5.11 Delay or Omission Not Waiver.  No delay or omission of
                       ----------------------------
the Trustee or of any Holder of the Debentures to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy, or
constitute a waiver of any such Event of Default or an acquiescence therein.

          Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

          Section 5.12 Control by Holders.  The Holders of a majority in
                       ------------------
principal amount of the Outstanding Debentures of any series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the

                                      53
<PAGE>

Trustee or exercising any trust or power conferred on the Trustee, with respect
to the Debentures of such series, provided that:

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

               (b) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction, and

               (c) subject to the provisions of Section 6.1, the Trustee shall
have the right to decline to follow such direction if the Trustee in good faith
shall, by a Responsible Officer or Officers of the Trustee, determine that the
proceeding so directed would be unjustly prejudicial to the Holders not joining
in any such direction or would involve the Trustee in personal liability.

          Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, with respect to the Debentures and, if all or part of the Debentures
is represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Debentures entitled to join in such notice,
which record date shall be at the close of business on the day the Trustee
receives such notice.  The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such Holders remain Holders after such record date, provided,
                                                                   --------
that, unless the Holders of a majority in principal amount of the Outstanding
Debentures shall have joined in such notice prior to the day which is 90 days
after such record date, such notice shall automatically and without further
action by any Holder be canceled and of no further effect.  Nothing in this
paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after
expiration of such 90-day period, a new notice identical to a notice which has
been canceled pursuant to the proviso to the preceding sentence, in which event
a new record date shall be established pursuant to the provisions of this
Section 5.12.

          Section 5.13 Waiver of Past Defaults.  Subject to Section 9.2 hereof,
                       -----------------------
the Holders of not less than a majority in principal amount of the Outstanding
Debentures of any series may on behalf of the Holders of all the Debentures
of such series waive any past default hereunder with respect to Debentures and
its consequences, except a default:

               (a) in the payment of the principal of (or premium, if any) or
interest (including any Additional Interest) on the Debentures (unless such
default

                                      54
<PAGE>

has been cured and a sum sufficient to pay all matured installments of interest
and principal due otherwise than by acceleration has been deposited with the
Trustee), or

               (b) in respect of a covenant or provision hereof which under
Article 9 cannot be modified or amended without the consent of the Holder of
each Outstanding Debenture[; provided, however, that if the Debentures are held
                             --------  -------
by the Trust or a trustee of the Trust, such waiver shall not be effective until
the holders of a majority in liquidation amount of Preferred Securities shall
have consented to such waiver; provided, further, that if the consent of the
                               --------  -------
Holder of each outstanding Debenture is required, such waiver shall not be
effective until each holder of the Trust Securities shall have consented to such
waiver].

          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.  [If the Holders of a
majority in aggregate principal amount of the Outstanding Debentures fail to
waive such Event of Default, the holders of a majority in aggregate liquidation
amount of Preferred Securities shall have such right.]  No such rescission shall
affect any subsequent default or impair any right consequent thereon.

          Section 5.14 Undertaking for Costs.  All parties to this Indenture
                       ---------------------
agree, and each Holder of any Debenture by his acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, 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, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Debentures, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium, if any) or interest
(including any Additional Interest) on the Debentures on or after the Maturity
of the Debentures or to convert a Debenture in accordance with Article 13.

          Section 5.15 Waiver of Usury, Stay, or Extension Laws.  The Company
                       ----------------------------------------
covenants (to the extent that it may lawfully do so) that it will not at any
time

                                      55
<PAGE>

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

                                  THE TRUSTEE

          Section 6.1  Certain Duties and Responsibilities.  (a)  Except during
                       -----------------------------------
the continuance of an Event of Default,

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

                       (ii)  in the absence of bad faith on its part, the
     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 the 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 the
     Trustee, the Trustee shall be under a duty to examine the same to determine
     whether or not they conform to the requirements of this Indenture.

                 (b)   In case an Event of Default has occurred and is
continuing, the Trustee 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 person would exercise or use under the circumstances in
the conduct of his own affairs.

<PAGE>

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

                       (i)   this Subsection shall not be construed to limit the

The recitals contained herein and in the Debentures, except the Trustee's

and the Trustee assumes no responsibility for their correctness.  The Trustee

Securities Registrar or any other agent of the Company, in its individual or any

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

                                      59
<PAGE>

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

               (b)   to reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel); and

               (c)   to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense (including the reasonable compensation

administration of this trust or the performance of its duties hereunder,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder. This indemnification shall survive the resignation or removal

          To secure the Company's payment obligations in this Section, the
Company and the Holders agree that the Trustee shall have a lien prior to the

assets held in trust to pay principal and premium, if any, or interest on
particular Debentures pursuant to the discharge and defeasance provisions

satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(e) or (f) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Reform Act of 1978 or a successor statute.

to constitute conflicting interests.

Holder of a Debenture for at least six months may, on behalf of himself and all
other similarly situated Holders, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee.

               (e)  If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of Trustee for any cause
with respect to the Debentures, the Company, by a Board Resolution, shall
promptly

                                      62

appoint a successor Trustee. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Debentures shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Debentures delivered to the Company and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon
its acceptance of such appointment, become the successor Trustee and supersede
the successor Trustee appointed by the Company. If no successor Trustee shall

the manner hereinafter provided, any Holder who has been a bona fide Holder of a
Debenture for at least six months may, subject to Section 5.14, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee.

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

--------
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee and any agency
appointments of the Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.
In case any Debentures shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Debentures so authenticated, and in case any Debentures shall not have been
authenticated, any successor to the Trustee may authenticate such Debentures
either in the name of any predecessor Trustee or in the name of such successor
Trustee, and in all cases the certificate of authentication shall have the full
force which it is provided anywhere in the Debentures or in this Indenture that
the certificate of the Trustee shall have.

          Section 6.13 Preferential Collection of Claims Against Company.  If
                       -------------------------------------------------

                       -----------------------------------
appoint an Authenticating Agent or Agents with respect to the Debentures which
shall be authorized to act on behalf of the Trustee to authenticate the
Debentures issued upon exchange, registration of transfer or partial redemption
thereof, and Debentures so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.  Wherever reference is made in this
Indenture to the authentication and delivery of Debentures by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent.  Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and

                                      64
<PAGE>

doing business under the laws of the United States of America, or of any State,
Territory or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenti cating Agent shall
resign immediately in the manner and with the effect specified in this Section.

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

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of the
Debentures.  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 provision of this Section.

          The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

authenticate and shall deliver any Debentures which previously shall have been
signed and delivered by the officers of the Company to the Trustee for
authentication pursuant to such provisions and any Debentures which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee on its behalf for the purpose pursuant to such provisions. All the
Debentures so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Debentures theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Debentures had
been issued at the date of the execution hereof.

          In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form may be made in the Debentures thereafter to
be issued as may be appropriate.

accepting the additional trusts created by any supplemental indenture permitted

          Section 9.4  Effect of Supplemental Indentures.  Upon the execution of
                       ---------------------------------
any supplemental indenture under this Article, this Indenture shall be modified
in accordance therewith, and such supplemental indenture shall form a part of

or thereafter authenticated and delivered hereunder shall be bound thereby.

          Section 10.1   Payment of Principal, Premium and Interest.  The
                        -------------------------------------------
Company covenants and agrees for the benefit of the Holders of the Debentures
that it will duly and punctually pay the principal of (and premium, if any) and
interest (including Additional Interest) on the Debentures in accordance with
the terms of the Debentures and this Indenture.

              Section 10.2 Maintenance of Office or Agency.  The Company will
              --------------------------------------------
maintain in the United States an office or agency where Debentures may be
presented or surrendered for payment and an office or agency where Debentures
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Company in respect of the Debentures and this
Indenture may be served. The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Company shall fail to maintain
such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

                                      74

          The Company may also from time to time designate one or more other
offices or agencies where the Debentures may be presented or surrendered for any
or all of such purposes, and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
United States for such purposes.  The Company will give prompt written notice to
the Trustee of any such designation and any change in the location of any such
office or agency.

          Section 10.3 Money for Debenture Payments to Be Held in Trust.  If the
                       ------------------------------------------------
Company shall at any time act as its own Paying Agent with respect to the
Debentures, it will, on or before each due date of the principal of (and
premium, if any) or interest on any of the Debentures, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its failure so to act.

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

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

          (a)  hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Debentures 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;

          (b)  give the Trustee notice of any default by the Company (or any
other obligor upon the Debentures) in the making of any payment of principal
(and premium, if any) or interest;

                                      75
<PAGE>

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

          (d)  comply with the provisions of the Trust Indenture Act applicable
to it as a Paying Agent.

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

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Debenture and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall (unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be paid on Company Request, after all
payments owing the Trustee have been paid, to the Company, or (if then held by
the Company) shall (unless otherwise required by mandatory provision of
applicable escheat or abandoned or unclaimed property law) be discharged from
such trust; and the Holder of such Debenture shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease.

          Section 10.4 Payment of Taxes and Other Claims.  The Company will pay
                       ---------------------------------
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or upon the income, profits or property of the Company,
and (b) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company; provided, however,
                                                             --------  -------
that the Company shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

ending after the date hereof an Officers' Certificate (signed by at least one of
the officers referred to in Section 314(a)(4) of the Trust Indenture Act)
covering the preceding calendar year, stating whether or not to the best
knowledge of the signers thereof the Company is in default in the performance,
observance or fulfillment of or compliance with any of the terms, provisions,
covenants and conditions of this Indenture, and if the Company shall be in
default, specifying all such defaults and the nature and status thereof of which
they may have knowledge.  For the purpose of this Section 10.5, compliance shall
be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

          Section 10.6 Waiver of Certain Covenants.  The Company may omit in any
                       ---------------------------
particular instance to comply with any covenant or condition set forth in this
Article 10, if before or after the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Debentures, 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 in
respect of any such covenant or condition shall remain in full force and effect.

may be necessary in order that the amount of distributions (including any
Additional Amounts (as defined in the Trust Agreement)) then due and payable by
the Trust on the Preferred Securities and Common Securities that at any time
remain outstanding in accord with the terms thereof shall not be reduced as a
result of any Additional Taxes (the "Additional Sums").  Whenever in this
Indenture or the Debentures there is a reference in any context to the payment
of principal of or interest on the Debentures, such mention shall be deemed to
include mention of the payments of the Additional Sums provided for in this
paragraph to the extent that, in such context, Additional Sums are, were or
would be payable in respect thereof pursuant to the provisions of this paragraph
and express mention of the payment of Additional Sums (if applicable) in any
provisions hereof shall not be construed as excluding Additional Sums in those
provisions hereof where such express mention is not made; provided, however,
that the extension of an interest payment period pursuant to Section 3.11 or
the Debentures shall not extend the payment of any Additional Sums that may be
due and payable during such interest payment period.]

liquidation of the Trust or (b) in connection with certain mergers,
consolidations or amalgamations permitted by the Trust Agreement and (iv) to use

amount of Debentures to be redeemed.

          Section 11.2 Selection of Debentures to Be Redeemed.  If less than all
                       --------------------------------------
the Debentures are to be redeemed, the particular Debentures to be redeemed
shall be selected not more than 45 days prior to the Redemption Date by the
Trustee from the Outstanding Debentures not previously called for redemption, by
lot or by such other method as the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of a portion of the principal
amount of the Debentures Outstanding, provided that the unredeemed portion of
                                      --------
the principal amount of the Debentures be in an authorized denomination (which
shall not be less than the minimum authorized denomination) for the Debentures.

          The Trustee shall promptly notify the Company in writing of the
Debentures selected for partial redemption and 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 Debentures shall relate,
in the case of any Debenture redeemed or to be redeemed only in part, to the
portion of the principal amount of such Debenture which has been or is to be
redeemed. If the Company shall so direct, Debentures registered in the name of
the Company, any Affiliate or

          With respect to Debentures to be redeemed, each notice of redemption
shall state:

               (a)  the Redemption Date;

               (b)  the redemption price at which the Debentures are to be
redeemed (the "Redemption Price");

               (c)  if less than all Outstanding Debentures are to be redeemed,
the identification (and, in the case of partial redemption, the respective
principal amounts) of the particular Debentures to be redeemed (including, if
relevant, the CUSIP or ISIN number);

               (d)  that on the Redemption Date the Redemption Price will become
due and payable upon each such Debenture or portion thereof, and that upon
deposit with the Paying Agent interest thereon, if any, shall cease to accrue on
and after the Redemption Date;

               (e)  the place or places where the Debentures are to be
surrendered for payment of the redemption price at which the Debentures are to
be redeemed; and

               (f)  that a Holder of Debentures who desires to convert
Debentures called for redemption must satisfy the requirements for conversion
contained in the Debentures, the then existing conversion price or rate, and the
date and time when the option to convert shall expire.

          Notice of redemption of Debentures to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.
The notice if mailed in the manner herein provided shall be conclusively
presumed to

                                      80

have been duly given, whether or not the Holder receives such notice. In any
case, a failure to give such notice by mail or any defect in the notice to the
Holder of any Debenture designated for redemption as a whole or in part shall
not affect the validity of the proceedings for the redemption of any other
Debenture.

          Section 11.4 Deposit of Redemption Price.  Prior to 10:00 a.m., New
                       ---------------------------
York City time, on the Redemption Date specified in the notice of redemption
given as provided in Section 11.3, the Company will deposit with the Trustee or
with one or more Paying Agents (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Article 4) an amount of money
sufficient to redeem on the Redemption Date all the Debentures so called for
redemption at the applicable Redemption Price.

          If any Debenture called for redemption has been converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held in
trust for the redemption of such Debenture shall (subject to any right of the
Holder of such Debenture or any Predecessor Debenture to receive interest as
provided in the last paragraph of Section 3.7) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.

redemption has been given as provided in Section 11.3, the Debentures so to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified, including any accrued interest (and any Additional
Interest) thereon, and from and after such date (unless the Company shall
default in the payment of the Redemption Price or any accrued interest on
(including any Additional Interest)) such Debentures shall cease to bear
interest.  Upon surrender of any such Debenture for redemption in accordance
with said notice, such Debenture shall be paid by the Company at the Redemption
Price, including any accrued interest (and any Additional Interest) to the
Redemption Date, provided, however, that installments of interest on Debentures
                 --------  -------
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Debentures, or one of more Predecessor Debentures,
registered as such at the close of business on the relevant Regular Record Dates
or Special Record Dates, as the case may be, according to their terms and the
provisions of Section 3.7.

          If any Debenture called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid,

                                      81
<PAGE>

bear interest from the Redemption Date at the rate prescribed therefor in the
Debenture.

exchange any Debentures so selected for redemption, in whole or in part, except
for the unredeemed portion of any Debentures being redeemed in part.

          Any Debenture which is to be redeemed only in part shall be surren-
dered at the place of payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and make available for delivery to the Holder of
such Debenture without service charge, a new Debenture or Debentures, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Debenture so surrendered. Each Debenture shall be subject to partial
redemption only in the amount of [$1,000] or integral multiples thereof.

          The Debentures are not entitled to the benefit of any sinking or like
fund.

                          SUBORDINATION OF DEBENTURES

          Section 12.1   Debentures Subordinate to Senior Debt.  The Company
                         -------------------------------------
covenants and agrees, and each Holder of a Debenture, by its acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter
set forth in this Article, the payment of the principal of (and premium, if any)
and interest (including any Additional Interest) on each and all of the
Debentures are hereby expressly made subordinate and subject in right of payment
to the prior payment in full in cash of all amounts then due and payable in
respect of all Senior Debt (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt and that no payment on account of
principal of, premium, if any, or interest on the Debentures and no acquisition
of, or payment on account of any sinking fund for, the Debentures may be made
unless full payment of all amounts then due for principal, premium, if any, and
interest then due on all Senior Debt (by maturity, lapse of time, acceleration
or otherwise) has been made or duly provided for in cash or in a manner
satisfactory to the holders of such Senior Debt.

          Section 12.2   Payment Over of Proceeds Upon Dissolution, Etc.  Upon
                         -----------------------------------------------
any distribution of the Company's assets in connection with any dissolution,
winding up, liquidation or reorganization of the Company, whether voluntary or
involuntary, in bankruptcy, insolvency or receivership proceedings (each such
event, if any, herein sometimes referred to as a "Proceeding"), or upon an
assignment for the benefit of creditors or otherwise: (i) all Senior Debt
(including without limitation all interest accruing on or after the filing of
any petition in bankruptcy relating to the Company at the relevant contractual
rate, whether or not such claim for post-petition interest is allowed in such
proceeding) must be paid in full in cash before the Holders of the Debentures
are entitled to any payments or distributions of any kind or character
(including any payment or distribution which may be payable or deliverable by
reason of the payment of any other Debt of the Company (including the
Debentures) subordinated to the payment of the Debentures), and (ii) any payment
or distribution of the Company's assets of any kind or character, whether in
cash, securities or other property, which would otherwise (but for these
subordination provisions) be payable or deliverable in respect of the Debentures
shall be paid or delivered directly to the holders of such Senior Debt (or their
representative or trustee) in accordance with the priorities then existing among
such holders until all

                                      85
<PAGE>

Senior Debt shall have been paid in full in cash before any payment or
distribution is made to the Holders of the Debentures.

          In the event that notwithstanding the subordination provisions set
forth herein, any payment or distribution of assets of any kind or character is
made on the Debentures at a time when the respective payment is not permitted to
be made as a result of the subordination provisions described above and before
all Senior Debt is paid in full in cash, the Trustee or the Holders of the
Debentures receiving such payment will be required to pay over such payment or
distribution to the holders of such Senior Debt.

          For the purposes of this Article only, the words "any payment or
distribution of any kind or character" shall not be deemed to include shares of
stock of the Company as reorganized or readjusted, or securities of the Company
or any other Person provided for by a plan of reorganization or
readjustment which securities are subordinated in right of payment to all then
outstanding Senior Debt to substantially the same extent as the Debentures are
so subordinated as provided in this Article.  The consolidation of the Company
with, or the merger of the Company into, another Person or the liquidation or
dissolution of the Company following the sale of all or substantially all of its
properties and assets as an entirety to another Person upon the terms and
conditions set forth in Article 8 shall not be deemed a Proceeding for the
purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or the Person which acquires by sale such properties
and assets as an entirety, as the case may be, shall, as a part of such
consolidation, merger, or sale comply with the conditions set forth in Article
Eight.

          Section 12.3   No Payment When Senior Debt in Default.  (a)  In the
                         --------------------------------------
event and during the continuation of any default in the payment of principal of
(or premium, if any) or interest on, or other amounts owing with respect to, any
Senior Debt, or in the event that any event of default with respect to any
Senior Debt shall have occurred and be continuing and shall have resulted in
such Senior Debt becoming or being able to be declared due and payable prior to
the date it would otherwise have become due and payable, unless and until such
event of default shall have been waived or shall have ceased to exist and such
acceleration shall have been rescinded or annulled, or (b) in the event any
judicial proceeding shall be pending with respect to any such default in payment
or such event or default, then, no payment or distribution of any kind or
character, whether in cash, properties or Debentures shall be made by the
Company on account of principal of (or premium, if any) or interest (including
any Additional Interest), if any, on the Debentures or on

                                      86
<PAGE>

account of the purchase or other acquisition of Debentures by the Company or any
Subsidiary other than payments made from funds on deposit pursuant to Section
4.1 or from funds on deposit for the redemption of Debentures for which notice
of redemption has been given and the Redemption Date has passed.

          The Company shall give prompt written notice to the Trustee of any
default of the type described in the preceding paragraph in respect of Senior
Debt; provided that no failure to give such a notice shall have any effect
whatsoever on the subordination provisions described herein.

          In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of the Debentures prohibited by
the foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known as set forth in Section 12.9, to
the Trustee or, as the case may be, such Holder, then and in such event such
payment shall be paid over and delivered forthwith to the Company.

          The provisions of this Section shall not apply to any payment with
respect to which Section 12.2 would be applicable.

          Section 12.4   Payment Permitted If No Default.  Nothing contained in
                         -------------------------------
this Article or elsewhere in this Indenture or in any of the Debentures shall
prevent (a) the Company, at any time except during the pendency of any
Proceeding referred to in Section 12.2 or under the conditions described in
Sections 12.3, from making payments at any time of principal of (and premium, if
any) or interest on the Debentures, or (b) except with respect to the payment
over provisions of this Article 12, the application by the Trustee of any money
deposited with it hereunder to the payment of or on account of the principal of
(and premium, if any) or interest (including any Additional Interest) on the
Debentures or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, the Trustee did not have actual knowledge that
such payment would have been prohibited by the provisions of this Article.

          Section 12.5   Subrogation to Rights of Holders of Senior Debt.
                         -----------------------------------------------
Subject to the payment in full in cash of all Senior Debt, or the provision for
such payment in cash or cash equivalents or otherwise in a manner satisfactory
to the holders of Senior Debt, the Holders of the Debentures shall be subrogated
to the extent of the payments or distributions made to the holders of such
Senior Debt pursuant to the provisions of this Article (equally and ratably with
the holders of all

                                      87
<PAGE>

indebtedness of the Company which by its express terms is subordinated to Senior
Debt of the Company to substantially the same extent as the Debentures are
Subordinated to the Senior Debt and is entitled to like rights of subrogation
by reason of any payments or distributions made to holders of such Senior Debt)
to the rights of the holders of such Senior Debt to receive payments and
distributions of cash, property and securities applicable to the Senior Debt
until the principal of (and premium, if any) and interest on the Debentures
shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Debt of any cash, property or
securities to which the Holders of the Debentures or the Trustee would be
entitled except for the provisions of this Article, and no payments pursuant to
the provisions of this Article to the holders of Senior Debt by Holders of the
Debentures or the Trustee, shall, as among the Company, its creditors other than
holders of Senior Debt, and the Holders of the Debentures, be deemed to be a
payment or distribution by the Company to or on account of the Senior Debt.

          Section 12.6   Provisions Solely to Define Relative Rights.  The
                         -------------------------------------------
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders of the Debentures on the one hand
and the holders of Senior Debt on the other hand.  Nothing contained in this
Article or elsewhere in this Indenture or in the Debentures is intended to or
shall (a) impair, as between the Company and the Holders of the Debentures, the
obligations of the Company, which are absolute and unconditional, to pay to the
Holders of the Debentures the principal of (and premium, if any) and interest
(including any Additional Interest) on the Debentures as and when the same shall
become due and payable in accordance with their terms, or (b) affect the
relative rights against the Company of the Holders of the Debentures and
creditors of the Company other than their rights in relation to the holders of
Senior Debt, or (c) prevent the Trustee or the Holder of any Debenture from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture including, without limitation, filing and voting claims in any
Proceeding, subject to the rights, if any, under this Article of the holders of
Senior Debt to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

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

provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in

written notice to the Trustee of any fact known to the Company which would
prohibit the making of any payment to or by the Trustee in respect of the
Debentures. Notwithstanding the provisions of this Article or any other
provision of this Indenture, the Trustee shall not be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee in respect of the Debentures, unless and until the Trustee
shall have received written notice thereof from the Company or a person
representing itself as a holder of Senior Debt or from any trustee, agent or
representative therefor (whether or not the facts contained in such notice are
true).

Company and be then acting hereunder, the term "Trustee" as used in this Article
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intent and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee.

          Section 12.14  Certain Conversions or Exchanges Deemed Payment. For
                         -----------------------------------------------
the purpose of this Article only, (a) the issuance and delivery of junior
securities upon conversion or exchange of Debentures shall not be deemed to
constitute a payment or distribution on account of the principal of (or premium,
if any) or interest (including any Additional Interest) on the Debentures or on
account of the purchase or other acquisition of Debentures, and (b) the payment,
issuance or delivery of cash (including any payments for fractional shares),
property or securities (other than junior securities) upon conversion or
exchange of a Debenture shall be deemed to constitute payment on account of the
principal of such Debenture.  For the purpose of this Section, the term "junior
securities" means (i) shares of any stock of any class of the Company and (ii)
securities of the Company which are subordinated in right of payment to all
Senior Debt which may be outstanding at the time of issuance or delivery of such
securities to substantially the same extent as, or to a greater extent than, the
Debentures are so subordinated as provided in this Article.

          Section 12.15  Trust Moneys Not Subordinated.  Notwithstanding
                         -----------------------------
anything contained herein to the contrary (provided that at the time deposited,
                                           --------
such deposit did not violate any then outstanding Senior Debt), payments from
money or the proceeds of Government Obligations held in trust under Article 4 by
the Trustee

                                      90
<PAGE>

for the payment of principal of and interest on the Debentures shall not be
subordinated to the prior payment of any Senior Debt or subject to the
restrictions set forth in this Article 12, and none of the Holders shall be
obligated to pay over any such amount to the Company or any holder of Senior
Debt of the Company or any other creditor of the Company.

                                  ARTICLE XII

                            [CONVERSION OF DEBENTURES

          Section 13.1   Conversion Rights.  Subject to and upon compliance with
                         -----------------
the provisions of this Article, the Debentures are convertible, at the option of
the Holder, at any time prior to redemption or Maturity, into fully paid and
nonassessable shares of Common Stock of the Company at an initial conversion
rate of ______ shares of Common Stock for each $[1,000] in aggregate principal
amount of Debentures (equal to a conversion price of $______ per share of Common
Stock), subject to adjustment as described in this Article 13 (as adjusted the
"Conversion Price"). A Holder of Debentures may convert any portion of the
principal amount of the Debentures into that number of fully paid and
nonassessable shares of Common Stock (calculated as to each conversion to the
nearest 1/100th of a share) obtained by dividing the principal amount of the
Debentures to be converted by the Conversion Price. In case a Debenture or
portion thereof is called for redemption, such conversion right in respect of
the Debenture or portion so called shall expire at the close of business on the
Business Day immediately preceding the corresponding Redemption Date, unless the
Company defaults in making the payment due upon redemption.

          Section 13.2   Conversion Procedures.  (a)  In order to convert all or
                         ---------------------
a portion of the Debentures, the Holder thereof shall deliver to the [Property
Trustee, as] conversion agent or to such other agent appointed for such purposes
(the "Conversion Agent") an irrevocable Notice of Conversion setting forth the
principal amount of Debentures to be converted, together with the name or names,
if other than the Holder, in which the shares of Common Stock should be issued
upon conversion and, if such Debentures are definitive Debentures, surrender to
the Conversion Agent the Debentures to be converted, duly endorsed or assigned
to the Company or in blank. [In addition, a holder of Preferred Securities may
exercise its right under the Trust Agreement to convert such Preferred
Securities into Common Stock by delivering to the Conversion Agent an
irrevocable Notice of Conversion setting forth the information called for by the
preceding sentence and directing the Conversion

                                      91
<PAGE>

Agent (i) to exchange such Preferred Security for a portion of the Debentures
held by the Trust (at an exchange rate of $50 principal amount of Debentures for
each Preferred Security) and (ii) to immediately convert such Debentures, on
behalf of such holder, into Common Stock of the Company pursuant to this Article
13 and, if such Preferred Securities are in definitive form, surrendering such
Preferred Securities, duly endorsed or assigned to the Company or in blank. So
long as any Preferred Securities are outstanding, the Trust shall not convert
any Debentures except pursuant to a Notice of Conversion delivered to the
Conversion Agent by a holder of Preferred Securities.]

          If a Notice of Conversion is delivered on or after the Regular Record
Date and prior to the subsequent Interest Payment Date, the Holder of record on
the Regular Record Date will be entitled to receive the interest paid on the
subsequent Interest Payment Date on the portion of Debentures to be converted
notwithstanding the conversion thereof prior to such Interest Payment Date.
Except as otherwise provided in the immediately preceding sentence, in the case
of any Debenture which is converted, interest whose Stated Maturity is on or
after the date of conversion of such Debenture shall not be payable, and the
Company shall not make nor be required to make any other payment, adjustment or
allowance with respect to accrued but unpaid interest on the Debentures being
converted, which shall be deemed to be paid in full.  Each conversion shall be
deemed to have been effected immediately prior to the close of business on the
day on which the Notice of Conversion was received (the "Conversion Date") by
the Conversion Agent from the Holder or from a holder of the Preferred
Securities effecting a conversion thereof pursuant to its conversion rights
under the Trust Agreement, as the case may be.  The Person or Persons entitled
to receive the Common Stock issuable upon such conversion shall be treated for
all purposes as the record holder or holders of such Common Stock as of the
Conversion Date and such Person or Persons will cease to be a record Holder or
record Holders of the Debentures on that date.  As promptly as practicable on or
after the Conversion Date, the Company shall issue and deliver at the office of
the Conversion Agent, unless otherwise directed by the Holder or Holders in the
Notice of Conversion, a certificate or certificates for the number of full
shares of Common Stock issuable upon such conversion, together with the cash
payment, if any, in lieu of any fraction of any share to the Person or Persons
entitled to receive the same. The Conversion Agent shall deliver such
certificate or certificates to such Person or Persons.

          (b) The Company's delivery upon conversion of the fixed number of
shares of Common Stock into which the Debentures are convertible

                                      92
<PAGE>

(together with the cash payment, if any, in lieu of fractional shares) shall be
deemed to satisfy the Company's obligation to pay the principal amount at
Maturity of the portion of Debentures so converted and any unpaid interest
(including Additional Interest) accrued on such Debentures at the time of such
conversion.

          (c) No fractional shares of Common Stock will be issued as a result of
conversion, but in lieu thereof, the Company shall pay to the Conversion Agent a
cash adjustment in an amount equal to the same fraction of the Current Market
Price with respect to such fractional interest on the date on which the
Debentures or Preferred Securities, as the case may be, were duly surrendered to
the Conversion Agent for conversion, and the Conversion Agent in turn will make
such payment, if any, to the Holder of the Debentures or the holder of the
Preferred Securities so converted.

          (d) In the event of the conversion of any Debenture in part only, a
new Debenture or Debentures for the unconverted portion thereof will be issued
in the name of the Holder thereof upon the cancellation of the Debenture
converted in part in accordance with Section 3.5.

          (e) In effecting the conversion transactions described in this
Section, the Conversion Agent is acting [as agent of the holders of Preferred
Secuities (in the exchange of Preferred Securities for Debentures) and] as agent
of the Holders of Debentures (in the conversion of Debentures into Common
Stock)[, as the case may be,] directing it to effect such conversion
transactions. The Conversion Agent is hereby authorized [(i) to exchange
Debentures held by the Trust from time to time for Preferred Securities in
connection with the conversion of such Preferred Securities in accordance with
this Article 13 and (ii) [to convert all or a portion of the Debentures into
Common Stock and thereupon to deliver such shares of Common Stock in accordance
with the provisions of this Article 13 [and to deliver to the Trust a new
Debenture or Debentures for any resulting unconverted principal amount.]

          (f) The Company shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for issuance upon the
conversion of the Debentures, such number of shares of Common Stock as shall
from time to time be issuable upon the conversion of all the Debentures then
outstanding.  Notwithstanding the foregoing, the Company shall be entitled to
deliver upon conversion of Debentures shares of Common Stock reacquired and held
in the treasury of the Company (in lieu of the issuance of authorized and
unissued shares of Common Stock) so long as any such treasury shares are free
and clear of all liens,

                                      93
<PAGE>

charges, security interests or encumbrances. Whenever the Company issues shares
of Common Stock upon conversion of Debentures and the Company has in effect at
such time a share purchase rights agreement under which holders of Common Stock
are issued rights ("Rights") entitling the holders under certain circumstances
to purchase an additional share or shares of stock, the Company will issue,
together with each such share of Common Stock, such number of Rights (which
number may be a fraction) as shall at that time be issuable with a share of
Common Stock pursuant to such share purchase rights agreement. Any shares of
Common Stock issued upon conversion of the Debentures shall be duly authorized,
validly issued and fully paid and nonassessable. The Conversion Agent shall
deliver the shares of Common Stock received upon conversion of the Debentures to
the converting Holder free and clear of all liens, charges, security interests
and encumbrances, except for United States withholding taxes. The Company shall
use its best efforts to obtain and keep in force such governmental or regulatory
permits or other authorizations as may be required by law, and shall comply with
all applicable requirements as to registration or qualification of the Common
Stock (and all requirements to list the Common Stock issuable upon conversion of
Debentures that are at the time applicable), in order to enable the Company to
lawfully issue Common Stock upon conversion of the Debentures and to lawfully
deliver the Common Stock to each Holder upon conversion of the Debentures.

          (g) The Company will pay any and all taxes that may be payable in
respect of the issue or delivery of shares of Common Stock on conversion of
Debentures.  The Company shall not, however, be required to pay any tax which
may be payable in respect of any transfer involved in the issue and delivery of
shares of Common Stock in a name other than that in which the Debentures so
converted were registered, and no such issue or delivery shall be made unless
and until the Person requesting such issue has paid to the Conversion Agent the
amount of any such tax, or has established to the satisfaction of the Conversion
Agent that such tax has been paid.

          (h) Nothing in this Article 13 shall limit the requirement of the
Company to withhold taxes pursuant to the terms of the Debentures or as set
forth in this Agreement or otherwise require the Trustee or the Company to pay
any amounts on account of such withholdings.

          Section 13.3   Conversion Price Adjustments.  The conversion price
                         ----------------------------
shall be subject to adjustment (without duplication) from time to time as
follows:

                                      94
<PAGE>

          (a) In case the Company shall, while any of the Debentures are
outstanding, (i) pay a dividend or make a distribution with respect to its
Common Stock in shares of Common Stock, (ii) subdivide its outstanding shares of
Common Stock, (iii) combine its outstanding shares of Common Stock into a
smaller number of shares or (iv) issue by reclassification of its shares of
Common Stock any shares of capital stock of the Company, the conversion
privilege and the Conversion Price in effect immediately prior to such action
shall be adjusted so that the Holder of any Debentures thereafter surrendered
for conversion shall be entitled to receive the number of shares of capital
stock of the Company which he would have owned immediately following such action
had such Debentures been converted immediately prior thereto.  An adjustment
made pursuant to this subsection (a) shall become effective immediately after
the record date in the case of a dividend or other distribution and shall
become effective immediately after the effective date in case of a subdivision,
combination or reclassification (or immediately after the record date if a
record date shall have been established for such event).  If, as a result of an
adjustment made pursuant to this subsection (a), the Holder of any Debenture
thereafter surrendered for conversion shall become entitled to receive shares of
two or more classes or series of capital stock of the Company, the Board of
Directors (whose determination shall be conclusive and shall be described in a
Board Resolution filed with the Trustee) shall determine the allocation of the
adjusted Conversion Price between or among shares of such classes or series of
capital stock.  In the event that such dividend, distribution, subdivision,
combination or issuance is not so paid or made, the Conversion Price shall again
be adjusted to be the Conversion Price which would then be in effect if such
record date had not been fixed.

          (b) In case the Company shall, while any of the Debentures are
Outstanding, issue rights or warrants to all holders of its Common Stock
entitling them (for a period expiring within 45 days after the record date
mentioned below) to subscribe for or purchase shares of Common Stock at a price
per share less than the Current Market Price per share of Common Stock on the
record date mentioned below, the Conversion Price for the Debentures shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the date of issuance of such
rights or warrants by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding on the date of issuance of such rights or
warrants plus the number of shares which the aggregate offering price of the
total number of shares so offered for subscription or purchase would purchase at
such Current Market Price, and the denominator of which shall be the number of
shares of Common Stock outstanding on the date of issuance of such rights or
warrants plus the number of additional shares of Common

                                      95
<PAGE>

Stock offered for subscription or purchase. Such adjustment shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such rights or warrants. For the purposes of
this subsection, the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company. The Company shall
not issue any rights or warrants in respect of shares of Common Stock held in
the treasury of the Company. In case any rights or warrants referred to in this
subsection in respect of which an adjustment shall have been made shall expire
unexercised within 45 days after the same shall have been distributed or issued
by the Company, the Conversion Price shall be readjusted at the time of such
expiration to the Conversion Price that would have been in effect if no
adjustment had been made on account of the distribution or issuance of such
expired rights or warrants.

          (c) Subject to the last sentence of this subparagraph, in case the
Company shall, by dividend or otherwise, distribute to all holders of its Common
Stock evidences of its indebtedness, shares of any class or series of capital
stock, cash or assets (including securities, but excluding any rights or
warrants referred to in subparagraph (b), any dividend or distribution paid
exclusively in cash and any dividend or distribution referred to in subparagraph
(a) of this Section 13.3), the Conversion Price shall be reduced so that the
same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the effectiveness of the Conversion Price reduction
contemplated by this subparagraph (c) by a fraction, the numerator of which
shall be the Current Market Price per share of the Common Stock on the date
fixed for the payment of such distribution (the "Reference Date") less the
fair market value (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of
Directors), on the Reference Date, of the portion of the evidences of
indebtedness, shares of capital stock, cash and assets so distributed applicable
to one share of Common Stock, and the denominator of which shall be such Current
Market Price per share of the Common Stock, such reduction to become effective
immediately prior to the opening of business on the day following the
Reference Date.  In the event that such dividend or distribution is not so paid
or made, the Conversion Price shall again be adjusted to be the Conversion Price
which would then be in effect if such dividend or distribution had not occurred.
For purposes of this subparagraph (c), any dividend or distribution that
includes shares of Common Stock or rights or warrants to subscribe for or
purchase shares of Common Stock shall be deemed instead to be (i) a dividend or
distribution of the evidences of indebtedness, shares of capital stock, cash or
assets other than such shares of Common Stock or such rights or warrants (making
any Conversion Price reduction required by this

                                      96
<PAGE>

subparagraph (c)) immediately followed by (ii) a dividend or distribution of
such shares of Common Stock or such rights or warrants (making any further
conversion price reduction required by subparagraph (a) or (b)), except (A) the
Reference Date of such dividend or distribution as defined in this subparagraph
shall be substituted as (x) "the record date in the case of a dividend or other
distribution," and (y) "the record date for the determination of stockholders
entitled to receive such rights or warrants" and (z) "the date fixed for such
determination" within the meaning of subparagraphs (a) and (b) and (B) any
shares of Common Stock included in such dividend or distribution shall not be
deemed outstanding for purposes of computing any adjustment of the conversion
price in subparagraph (a).

          (d) In case the Company shall pay or make a dividend or other
distribution on its Common Stock exclusively in cash (excluding all cash
dividends, if the annualized amount thereof per share of Common Stock does not
exceed 12.5% of the Current Market Price per share of the Common Stock on the
trading day immediately preceding the date of declaration of such dividend), the
Conversion Price shall be reduced so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (d) by a fraction, the numerator of which shall be the Current
Market Price per share of the Common Stock on the date fixed for the payment of
such distribution less the amount of cash so distributed (excluding that portion
of such distribution that does not exceed 12.5% of the Current Market Price per
share, determined as provided above) applicable to one share of Common Stock and
the denominator of which shall be such Current Market Price per share of the
Common Stock, such reduction to become effective immediately prior to the
opening of business on the day following the date fixed for the payment of such
distribution; provided, however, that in the event the portion of the cash so
              --------  -------
distributed applicable to one share of Common Stock is equal to or greater than
the Current Market Price per share of the Common Stock on the record date
mentioned above (excluding that portion of such distribution that does not
exceed 12.5% of the Current Market Price per share, determined as provided
above), in lieu of the foregoing adjustment, adequate provision shall be made so
that each Holder of shares of Debentures shall have the right to receive upon
conversion the amount of cash such Holder would have received had such Holder
converted each share of the Debentures immediately prior to the record date for
the distribution of the cash (less that portion of such distribution that does
not exceed 12.5% of the Current Market Price per share, determined as provided
above).  In the event that such dividend or distribution is not so paid or made,
the Conversion Price

                                      97
<PAGE>

shall again be adjusted to be the conversion price which would then be in effect
if such record date had not been fixed.

          (e) In case a tender or exchange offer (other than an odd-lot offer)
made by the Company or any Subsidiary of the Company for all or any portion of
the Common Stock shall expire and such tender or exchange offer shall involve
the payment by the Company or such Subsidiary of consideration per share of
Common Stock having a fair market value (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and described in a
resolution of the Board of Directors) at the last time (the "Expiration Time")
tenders or exchanges may be made pursuant to such tender or exchange offer (as
it shall have been amended) that exceeds 110% of the Current Market Price per
share of the Common Stock on the trading day next succeeding the Expiration
Time, the Conversion Price shall be reduced so that the same shall equal the
price determined by multiplying the Conversion Price in effect immediately prior
to the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (e) by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding (including any tendered or exchanged shares)
at the Expiration Time (including the Purchased Shares) (as defined below)
multiplied by the Current Market Price per share of the Common Stock on the
Trading Day next succeeding the Expiration Time and the denominator of which
shall be the sum of (x) the fair market value (deter  mined as aforesaid) of the
aggregate consideration payable to stockholders based on the acceptance (up to
any maximum specified in the terms of the tender or exchange offer) of all
shares validly tendered or exchanged and not withdrawn as of the Expiration Time
(the shares deemed so accepted, up to any such maximum, being referred to as the
"Purchased Shares") (excluding that portion of such consideration that does not
exceed 110% of the Current Market Price per share) and (y) the product of the
number of shares of Common Stock outstanding (less any Purchased Shares) at the
Expiration Time and the Current Market Price per share of the Common Stock on
the trading day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time.  In the event that such tender or exchange offer is not so
made, the Conversion Price shall again be adjusted to be the Conversion Price
which would then be in effect if such record date had not been fixed.

          (f) If the distribution date for the Rights of the Company provided in
a share purchase rights agreement occurs prior to the Conversion Date, and a
Holder of the Debentures who converts such Debentures after such distribution
date is not entitled to receive

                                      98
<PAGE>

the Rights that would otherwise be attached (but for the date of conversion) to
the shares of Common Stock received upon such conversion, then an adjustment
shall be made to the Conversion Price pursuant to clause (ii) of Section 13.4(a)
as if the Rights were being distributed to the common stockholders of the
Company immediately prior to such conversion. If such an adjustment is made and
the Rights are later redeemed, invalidated or terminated, then a corresponding
reversing adjustment shall be made to the Conversion Price, on an equitable
basis, to take account of such event.

          (g) The Company shall have the right to reduce from time to time the
Conversion Price by any amount selected by the Company for any period of at
least 30 days, provided, that the Company shall give at least 15 days' notice of
               --------
such reduction to the Trustee [and the Property Trustee]. The Company may, at
its option, make such reductions in the Conversion Price, in addition to those
set forth above in Section 13.4(a), as the Board of Directors deems advisable to
avoid or diminish any income tax to holders of Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes. No adjustment of the Conversion Price
will be made upon the issuance of any shares of Common Stock (or securities
convertible into or exercisable or exchangeable for Common Stock) except as
specifically described above including pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on securities of
the Company and the investment of additional optional amounts in shares of
Common Stock under any such plan, or the issuance of any shares of Common Stock
or options or rights to purchase such shares pursuant to any present or future
employee benefit plan or program of the Company or pursuant to any option,
warrant, right, or exercisable, exchangeable or convertible security which does
not constitute an issuance to all holders of Common Stock of rights or warrants
entitling holders of such rights or warrants to subscribe for or purchase Common
Stock at less than the Current Market Price. No adjustment in the Conversion
Price will be required unless such adjustment would require an increase or
decrease of at least 1% of the Conversion Price, but any adjustment that would
otherwise be required to be made shall be carried forward and taken into account
in a subsequent adjustment.

          (h) If any action would require adjustment of the Conversion Price
pursuant to more than one of the provisions described above, only one adjustment
shall be made and such adjustment shall be the amount of adjustment that has the
highest absolute value to the Holder of the Debentures.

          Section 13.4   Fundamental Change.  (a)  In the event that the Company
                         ------------------
is a party to any transaction (including, without limitation, a merger other
than a merger that does not result in a reclassification, conversion, exchange
or cancellation of Common Stock), consolidation, sale of all or substantially
all of the assets of the Company, recapitalization or reclassification of Common
Stock (other than a reclassification or recapitalization to which Section
13.3(a) is applicable) or any compulsory share exchange (each of the foregoing
being referred to as a "Transaction"), in each case, as a result of which
shares of Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (and subject to funds being legally
available for such purpose under applicable law at the time of such conversion),
securities, cash or other property, each Debenture shall thereafter be
convertible into the kind and, in the case of a Transaction which does not
involve a Fundamental Change, amount of securities, cash and other property
receivable upon the consummation of such Transaction by a holder of that number
of shares of Common Stock into which a Debenture was convertible immediately
prior to such Transaction, or (ii) in the case of a Transaction involving a
Common Stock Fundamental Change, common stock, each Debenture shall thereafter
be convertible (in the manner described herein) into common stock of the kind
received by holders of Common Stock (but in each case after giving effect to any
adjustment discussed in paragraphs (b) and (c) relating to a Fundamental Change
if such Transaction constitutes a Fundamental Change). The holders of
Debentures or Preferred Securities will have no voting rights with respect to
any Transaction described in this section.

               (b)  If any Fundamental Change occurs, then the Conversion Price
in effect will be adjusted immediately after such Fundamental Change as
described in paragraph (c) below. In addition, in the event of a Common Stock
Fundamental Change, each Debenture shall be convertible solely into common stock
of the kind received by holders of Common Stock as a result of such Common Stock
Fundamental Change.

               (c)  The Conversion Price in the case of any Transaction
involving a Fundamental Change will be adjusted immediately after such
Fundamental Change:

                    (1)  in the case of a Non-Stock Fundamental Change, the
          Conversion Price of the Debentures will thereupon become the lower of
          (A) the Conversion Price in effect immediately prior to such Non-Stock
          Fundamental Change, but after giving effect

                                      100
<PAGE>

          to any other prior adjustments, and (B) the result obtained by multi
          plying the greater of the Applicable Price or the then applicable
          Reference Market Price by a fraction, the numerator of which will be
          $50 and the denominator of which will be (x) the amount of the
          redemption price for each $50 aggregate principal amount of Debentures
          if the redemption date were the date of such Non-Stock Fundamental
          Change (or, for the period commencing on the first date of original
          issuance of the Debentures and through __________, 20__, and the
          twelve-month periods commencing __________, 20__ and __________, 20__,
          the product of _____%, _____% and ______%, respectively, multiplied by
          $50) plus (y) any then-accrued and unpaid interest on the Debentures;
          and

                    (2)  in the case of a Common Stock Fundamental Change, the
          Conversion Price of the Debentures in effect immediately prior to such
          Common Stock Fundamental Change, but after giving effect to any other
          prior adjustments, will thereupon be adjusted by multiplying such
          Conversion Price by a fraction, the numerator of which will be the
          Purchaser Stock Price and the denominator will be the Applicable
          Price; provided, however, that in the event of a Common Stock
          Fundamental Change in which (A) 100% of the value of the consideration
          received by a holder of Common Stock is common stock of the successor,
          acquiror, or other third party (and cash, if any, is paid only with
          respect to any fractional interests in such common stock resulting
          from such Common Stock Fundamental Change) and (B) all of the Common
          Stock will have been exchanged for, converted into, or acquired for
          common stock (and cash with respect to fractional interests) of the
          successor, acquiror, or other third party, the Conversion Price of the
          Debentures in effect immediately prior to such Common Stock
          Fundamental Change will thereupon be adjusted by multiplying such
          Conversion Price by a fraction, the numerator of which will be one and
          the denominator of which will be the number of shares of common stock
          of the successor, acquiror, or other third party received by a holder
          of one share of Common Stock as a result of such Common Stock
          Fundamental Change.

shares pursuant to any employee benefit plan or program of the Company or
pursuant to any option, warrant, right or exercisable, exchangeable or

<PAGE>

Debentures, upon the conversion thereof subsequent to the close of business on
the date fixed for the determination of stockholders entitled to receive such
distribution and prior to the effectiveness of the Conversion Price adjustment
in respect of such distribution, shall also be entitled to receive for each
share of Common Stock into which the Debentures are converted, the portion of
the shares of Common Stock, rights, warrants, evidences of indebtedness, shares
of capital stock, cash and assets so distributed applicable to one share of
Common Stock; provided, however, that, at the election of the Company (whose
              --------  -------
election shall be evidenced by a resolution of the Board of Directors) with
respect to all Holders so converting, the Company may, in lieu of distributing
to such Holder any portion of such distribution not consisting of cash or
securities of the Company, pay such Holder an amount in cash equal to the fair
market value thereof (as determined in good faith by the Board of Directors,
whose determination shall be conclusive and described in a resolution of the
Board of Directors). If any conversion of Debentures described in the
immediately preceding sentence occurs prior to the payment date for a
distribution to holders of Common Stock which the Holder of Debentures so
converted is entitled to receive in accordance with the immediately preceding
sentence, the Company may elect (such election to be evidenced by a resolution
of the Board of Directors) to distribute to such Holder a due bill for the
shares of Common Stock, rights, warrants, evidences of indebtedness, shares of
capital stock, cash or assets to which such Holder is so entitled, provided,
                                                                   --------
that such due bill (i) meets any applicable requirements of the principal
national securities exchange or other market on which the Common Stock is then
traded and (ii) requires payment or delivery of such shares of Common Stock,
rights, warrants, evidences of indebtedness, shares of capital stock, cash or
assets no later than the date of payment or delivery thereof to holders of
shares of Common Stock receiving such distribution.

employed, or herein or in any supplemental indenture provided to be employed, in
making the same.  Neither the Trustee nor any Conversion Agent shall be

                              EMPLOYMENT AGREEMENT

     THIS AGREEMENT is made as of December 4, 2000 by and between PSC Inc., a
New York corporation ("PSC" or the "Company") and EDWARD BOREY ("Executive").

                                    RECITALS

     WHEREAS, the Company desires to employ the Executive as its Chief Executive
Officer to devote full time to the business of PSC, and the Executive agrees to
be so employed.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
contained in this Agreement, the parties agree as follows:

     1.  Employment.  PSC hereby employs the Executive as President and Chief
         ----------
Executive Officer effective December 4, 2000 ("Employment Commencement Date").
Executive hereby accepts such employment and agrees to remain in the employ of
PSC for the Term to perform any and all reasonable and lawful duties prescribed
by PSC's Board of Directors and to abide by the terms and conditions of this
Agreement. During the Term, in good faith, Executive shall exert all reasonable
efforts to promote the interests of the Company and shall devote substantially
all of his entire working time, attention and energies to the business of the
Company. Effective as of the Employment Commencement Date, Executive will also
be elected a member of the Company's Board of Directors and will be appointed to
the Board of Director's Executive Committee. Executive shall be permitted to
serve on the board of directors of other companies so long as such service does
not adversely affect his performance under this Agreement and so long as such
other businesses are not competitive with Company.
<PAGE>

     2.  Term of Employment.  The term of employment under this Agreement shall
         ------------------
commence as of the Employment Commencement Date and shall terminate on December
31, 2003 (the "Initial Term"); provided, however that the term of this Agreement
shall be automatically extended for additional one year terms (each an
"Additional Term") upon the end of the Initial Term, or any successor Additional
Term unless either the Executive or the Company shall have given written notice
to the other at least four (4) months prior thereto that the term of this
Agreement shall not be so extended.

     3.  Compensation.
         ------------
         A.   Base Salary.  For all services to be rendered to the Company by
Executive in any capacity, including, without limitation, services as an
officer, director or member of any committee of the Board of Directors and the
performance of any duties assigned to him by the Board of Directors, PSC shall
pay to Executive a salary at the annual rate of not less than $360,000 ("Base
Salary"). The Base Salary of the Executive shall be reviewed annually by the
Board of Directors and may be increased from time to time in the sole discretion
of the Board of Directors. The Base Salary shall be payable in accordance with
the customary payroll practices of PSC, subject to such deductions and
withholdings as may be required by law or agreed to by Executive.

         B.  Performance Bonus ("Bonus")

               (i) For calendar year 2001, Executive will be paid a bonus of not
          less than 100% of his Base Salary.  If, and to the extent, PSC exceeds
          the Target established for 2001 under the Company's Management
          Incentive Plan ("MIP"), Executive shall be entitled to a bonus of up
          to an

                                       2
<PAGE>

          additional 50% of Base Salary, as may be determined by the Board of
          Directors.

               (ii) Pursuant to the MIP or any successor plan, for any calendar
          year after 2001 during the Initial Term or the Additional Term, if
          any, if and to the extent PSC achieves its pre-established performance
          goals for such calendar year, Executive shall be entitled to a
          performance bonus for such year in an amount equal to the percentage
          of his then existing Base Salary for such year set forth opposite the
          performance goal percentage below:

          % of Performance Goal Achieved      % of Base Salary
          ------------------------------      ----------------
           80% of Target                      30%
           100% of Target                     100%
           120% of Target                     150%

          To the extent the MIP conflicts with this Agreement with respect to
the foregoing, the terms of this Agreement shall prevail.

          C.  Insolvency.  In the event the Company is adjudicated insolvent,
              ----------
Executive shall be entitled to additional compensation to offset the decrease in
the likelihood that there will be any value to the Executive's equity potential
and Bonus potential; accordingly, Executive shall be entitled to a twofold
increase in Base Salary and payment of 2% of the total gross sales of the
Company assets in lieu of the Bonus payments.  If the insolvency is concluded
with a reorganization of the Company and operations resume, then the Executive's
compensation will revert to the provisions of subsections A and B.  These
additional payments are subject to applicable law,

                                       3
<PAGE>

including but not limited to appropriate review by the U.S. Bankruptcy Trustee
and the U.S. Bankruptcy Court.

     Also, in the event the Company is adjudicated insolvent, Executive shall be
entitled, at his discretion, to terminate his employment relationship with
Company upon sixty (60) days' written notice.  If such termination option is
exercised within one year from the Employment Commencement Date, Executive shall
be entitled to a severance payment equal to Executive's Base Salary for one year
and his bonus for one year at 100% of Target.  If such termination option is
exercised after one year from the Employment Commencement Date, Executive shall
be entitled to a severance payment equal to the greater of (a) Executive's Base
Salary and bonuses for the unexpired portion of the Term or (b) Executive's Base
Salary for one year and his bonus for one year at 100% of Target.  Such amount
will be payable in bi-weekly installments.  In addition, for the period during
which Executive is receiving severance payments pursuant to this section 3(C),
the Company will provide Executive with Executive's then current health, dental,
life and accidental death and dismemberment insurance benefits.

     4.  Benefits.  In addition to his Base Salary, Executive shall also be
         --------
entitled throughout the Term and the Additional Term, if any, to all benefits of
full time employees or officers as to which he meets the eligibility
requirements universally applicable to all employees and such other benefits as
may be accorded to other senior executives by written notification from the
Company given from time to time.  The benefits to which Executive is entitled
include those set forth on Exhibit A.  Executive shall also be entitled to four
weeks paid vacation in each calendar year.

                                       4
<PAGE>

     5.  Stock Option.  Pursuant to the Company's 1994 Stock Option Plan (the
         ------------
"Plan"), PSC hereby grants the Executive a stock option for 500,000 Common
Shares of  PSC at an exercise price equal to the Fair Market Value (as defined
in the Plan) of PSC's shares at the close of business on the Employment
Commencement Date, upon the terms and conditions set forth in the Stock Option
Agreement attached hereto as Exhibit B  If Executive is then an officer of the
Company, on each of January 2, 2002 and January 2, 2003, PSC will grant
Executive a stock option for no less than 75,000 shares pursuant to a stock
option agreement similar in form to the option agreements granted to other
officers of the Company.

     6.  Relocation Expenses.  The Company's headquarters will be in
         -------------------
Portland, Oregon.  Its main facilities will be in Eugene, Oregon.  Executive
will relocate to Portland, Oregon.  The Company will reimburse Executive for
reasonable relocation expenses in the manner and to the extent it shall be
agreed upon by the Company and Executive, after consultation with an outside
compensation consultant.  Such consultation shall take place no later than
December 20, 2000.  Company's reimbursement to Executive will compensate him for
any loss suffered as a result of the sale of his residence and for any
differential in the mortgage interest rate on a principal sum not in excess of
his current mortgage between the mortgage on his current home and the mortgage
on the home to be purchased in the Portland, Oregon area.  Company's
reimbursement will be fully grossed up to reimburse Executive for any federal or
state tax liability incurred as a result of the relocation reimbursement.

     7.  Confidential Information.  Executive acknowledges and agrees that
         ------------------------
Executive will be exposed to Confidential Information, knowledge or data as
described

                                       5
<PAGE>

below and Executive further acknowledges and agrees that such Confidential
Information, knowledge or data is proprietary to and a valuable trade secret of
the Company and that any disclosure or unauthorized use thereof will cause
irreparable harm and loss to the Company. Executive understands that the Company
has invested large sums in developing these materials and it would be difficult
for Executive to develop these same materials from any independent sources
without expenditure of large sums of money and effort. Executive also
acknowledges that any use of the Company's materials other than in the scope of
Executive's employment with the Company would constitute an unlawful use and
taking of the materials from the Company for which the Company would have
remedies against Executive.

          Executive agrees that during the period of Executive's employment by
the Company or by any parent or subsidiary of the Company and at all times
thereafter, Executive will not, directly or indirectly, disclose or authorize
anyone else to disclose or use or make known for Executive's or another's
benefit any Confidential Information, knowledge, or data of the Company whether
or not patentable or copyrightable, in any way acquired by Executive during
Executive's employment by the Company or by any parent or subsidiary of the
Company.  Confidential Information, knowledge or data of the Company shall, for
purposes of this Agreement, include, but not be limited to, matters not readily
available to the public which are:

          A.  of a technical nature, such as, but not limited to, methods, know-
how, formulae, compositions, drawings, blueprints, compounds, processes,
discoveries, machines, manufacturing procedures, techniques, computer databases,
source codes,

                                       6
<PAGE>

computer codes, designs, programs, prototypes, inventions, computer programs,
and similar items;

          B.  of a business nature such as, but not limited to, information
about sales or lists of customers (including mailing lists), vendors,
competitors, prices, costs, purchasing, profits, markets, sales and marketing
methods, documents, records, contract forms, computer disks containing data or
other materials and information relating to the products, services and business
of the Company, product strengths and weaknesses, business processes, business
and marketing plans and activities, financial information, and personnel
information;

          C.  pertaining to future developments such as, but not limited to,
research and development, or future marketing or merchandising plans or ideas.

          All records (whether in hard copy or digital form), books and computer
discs relating in any manner whatsoever to the Company shall be the exclusive
property of the Company regardless of who actually prepared the original record
or book.  Executive shall not copy or cause to have copied any such records and
books except in the ordinary course of business.  Immediately upon termination
of Executive's employment, Executive will deliver to the Company all copies of
data, information and knowledge, including, without limitation, all documents,
correspondence, specifications, blueprints, notebooks, reports, sketches,
formulae, computer programs, sales and other manuals, price lists, customer
lists, samples, and all other materials and copies thereof relating to the
business of the Company obtained by Executive during the period of Executive's
employment by the Company or by any parent or subsidiary of the Company which
are in Executive's possession or under Executive's control.

                                       7
<PAGE>

          The foregoing shall be in addition to any obligation Executive may
have under applicable law in respect of trade secrets and other legally
protected information.

     8.  Covenant Not to Compete
         -----------------------

          During the period of employment and during the Non-Compete Period (as
hereinafter defined) the Executive will not, directly or indirectly (a) own,
manage, operate, control or participate in the ownership, management, operation
or control of, or be connected as an officer, employee, partner, director,
consultant, independent contractor, principal, agent, stockholder or otherwise
with, or have any financial interest in, or aid or assist any other person in
the conduct of, any entity or business in any way competitive with the Business
of the Company (as hereinafter defined) on the date of termination of the
Executive's employment of any group, division or affiliate of the Company, in
any geographic area where such business is being conducted or, where the Company
is taking active steps to conduct the proposed business,  within one year of the
date of cessation of the Executive's employment, or (b) persuade or attempt to

the Company (including any party to whom the Company has made a sales proposal
within 18 months prior to the termination of employment of Executive) of the
type offered by the Company. However, nothing herein shall prevent Executive
from owning not more than five percent (5%) of the outstanding publicly traded
shares of common stock of a corporation, as to which corporation Executive has
no relationship other than as a shareholder. For purposes of this Agreement,
"Non-Compete Period" shall mean one of the following, whichever is applicable:
(a) a period of one year following Termination for Cause, (b) a period of one
year following the voluntary termination of employment by Executive, (c) a
period of one year following the termination of Executive's employment by the
Company pursuant to Section 10A(i) of this Agreement, or (d) a period of three
years following termination of employment as a result of a Change in Control.
Such period may be waived by the Board of Directors, at its discretion upon
written request of Executive.

          For purposes of this Agreement, "Business of the Company" is the
development, manufacturing and marketing of technologies, products, and services
for the automatic identification and keyless data entry industry, and includes,
but is not limited to, products, services, application, systems and technologies
relating to bar coded data, magnetic stripe encoded data, radio frequency
communications of bar coded or related data, optical character recognition,
machine vision as applied to the recognition of bar coded data and electronic
interchange of bar coded or related data.  The Business of the Company shall
also include any business in which the Company is actually engaged or as to
which it is doing research and development during

                                       9
<PAGE>

Executive's employment with the Company and, where the Company is taking active
steps to implement such research and development so as to result in commercial
enterprise within twelve (12) months from the date of Executive's termination of
employment. Notwithstanding the foregoing, Executive may be employed by a
division or subsidiary of a company that may be deemed to be a competitor of the
Company so long as such division or subsidiary is not engaged in the Business of
the Company and so long as the services of Executive are rendered exclusively to
such division or subsidiary. A technology, product, application, system or
service shall be considered as part of the Business of the Company if from the
Company's perspective it (i) is materially relevant to the Company's business,
or (ii) contributes not insignificant revenues to the overall results of the
Company, or (iii) commands a materially relevant position in the marketplace. An
entity will be considered competitive with the Company if from the Company's
perspective (i) one of such entity's strategic focuses competes with the
Company's technologies, products, applications, systems or services, or (ii)
such entity's competitive products contributes not insignificant revenues to
such entity.

          In the event of Executive's termination for any reason, the Company
and Executive will agree upon an exclusive list of entities to which the
Covenant not to Compete shall apply .

          Executive specifically agrees that because of Executive's special
expertise and the special and unique services that Executive will be furnishing
the Company, and because of the Confidential Information that will be disclosed
to Executive during Executive's employment, the above stated geographic areas
and time period, in and during which Executive will not compete with the
Company, are reasonable in scope

                                       10
<PAGE>

and duration and are necessary to afford the Company just and adequate
protection against the irreparable damage which would result to the Company from
any activities prohibited by this Section.

          In connection with the foregoing provisions of this Section 8, the
Executive represents that Executive's experience, capabilities and circumstances
are such that such provisions will not unreasonably prevent Executive from
earning a livelihood and that the limitations set forth herein are reasonable
and properly required for the adequate protection of the Company and its
affiliates.

          If Executive in any way breaches the obligations specified in this
Section 8, the Company shall have the right, in addition to any other remedies
available to it, to terminate the further payment of any amounts due, any
compensation, any severance payments, or any benefits.

          If the geographic or time restriction contained in this Section 8
shall be determined by an arbitrator or court of law or equity to be
unreasonable, the arbitrator or court may amend this Section 8 to provide a
reasonable geographic or time restriction which shall then be binding upon the
Company and the Executive.

     9.  Injunctive Relief.  Executive agrees that in the event of a breach or
         -----------------
threatened breach by the Employee of any of the provisions of Sections 7 or 8
hereof, the Company shall be entitled to an injunction restraining the Executive
from such breach or threatened breach without posting any bond or other
security.  Nothing herein, however, shall be construed as prohibiting the
Company from pursuing, in conjunction with an injunction or otherwise, any other
remedies available to the

                                       11
<PAGE>

Company for such breach or threatened breach, including the recovery of damages
from the Executive.

     10.  Severance Payment.
          -----------------

          A.  Termination of Employment by Company - In General.

               (i) In the event of the termination of employment of Executive by
          the Company prior to the expiration of the Term or an Additional Term,
          as the case may be, for any reason other than Termination for Cause
          (as hereinafter defined), death, disability, or a Change in Control
          (as hereinafter defined), or in the event of the termination of
          employment by Executive for Good Reason (as hereinafter defined), the
          Company will continue to pay the Executive following such termination
          an amount equal to the greater of (a) Executive's Base Salary and
          bonuses at 100% of Target for the unexpired portion of the Term or (b)
          Executive's Base Salary for one year and his bonus for one year at
          100% of Target.  Such amount shall be payable in bi-weekly
          installments either during the unexpired portion of the Term or for a
          period of one year, whichever period is applicable.  In addition, the
          Company will provide Executive with Executive's then current health,
          dental, life and accidental death and dismemberment insurance benefits
          for the unexpired term of the Agreement, or a period of one year
          following such termination, whichever is greater.  In the event of
          Executive's death while receiving severance payments hereunder, all
          remaining severance installment payments otherwise payable to
          Executive hereunder will be paid in the same

                                       12
<PAGE>

          amounts and in the same manner to Executive's heirs and legal
          representatives. All payments made to Executive hereunder will be
          subject to all applicable employment and withholding taxes.

               (ii) If Executive is receiving severance payments pursuant to
          Section 10A(i)above, then if at any time during the period Executive
          is receiving such severance payments, Executive receives or has the
          right to receive compensation (whether in cash, stock or otherwise)
          ("Third Party Compensation") from any source, either directly or
          indirectly, for services rendered in any capacity, whether as an
          employee, consultant, independent contractor, partner, officer, or
          otherwise, all such Third Party Compensation whether paid currently or
          deferred in any manner, shall be offset against the severance payments
          due from the Company in the following manner:  (a) no offset shall be
          made until after Executive receives severance payments equal to his
          Base Salary for one year and his bonus for one year at 100% of Target,
          (b) if, after the payments have been made pursuant to (a) above, the
          Third Party Compensation is greater than the amount that would be paid
          to Executive for the balance of the unexpired portion of the Term,
          than all of such Third Party Compensation shall be offset against the
          severance payments due from the Company, or (c) if, after the payments
          have been made pursuant to (a) above,  the Third Party Compensation is
          less than the amount that would be paid to Executive for the balance
          of the unexpired portion of the term, then all of such Third Party
          Compensation shall be offset against the

                                       13
<PAGE>

          severance payments due from the Company and the Company shall pay to
          Executive the difference between the two such amounts. Executive
          agrees to provide the Company with periodic reports of any and all
          such Third Party Compensation. Notwithstanding the foregoing, Third
          Party Compensation shall not include fees received by the Executive as
          a result of his service on the board of directors of other companies.

          B.  Termination of Employment - Change in Control.  In the event of
the termination of employment of Executive within the two year period following
a Change in Control (as hereinafter defined) of the Company, and such
termination is (i) by the Company or its successor for any reason other than
Termination for Cause (as hereinafter defined), death or disability, or (ii) by
the Executive for "Good Reason" (as hereinafter defined), the Company or its
successor will pay the Executive over a period of three years following such
termination an amount equal to the product of the sum of (x) Executive's Base
Salary at the annual rate then in effect in addition to  (y) the highest annual
bonus paid to Executive under the Company's current Management Incentive Plan or
any successor plan in the three full fiscal years preceding termination
multiplied by 2.9.  Such amount shall be payable in bi-weekly installments.  In
addition, Executive will be immediately vested in any retirement, incentive,
restricted stock, or option plans or agreements then in effect and the Company
will continue to provide Executive with Executive's then current health, dental,
life and accidental death and dismemberment insurance benefits for a period of
three years.  All payments made to Executive hereunder will be subject to all
applicable employment and withholding taxes.

                                       14
<PAGE>

          C.  Limitations.  Notwithstanding anything in this Section to the
              -----------
contrary, the maximum amount of cash and other benefits payable (whether on a
current or deferred basis and whether or not includible in income for income tax
purposes) under this Section (the "Severance Benefits") shall be limited to the
extent necessary to avoid causing any portion of such Severance Benefits, or any
other payment in the nature of compensation to the Executive, to be treated as a
"parachute payment" within the meaning of Section 280G(b)(2) of the Internal
Revenue Code of 1986, as amended.  Any adjustment required to satisfy the
limitation described in the preceding sentence shall be accomplished first by
reducing any cash payments that would otherwise be made to the Executive and
then, if further reductions are necessary, by adjusting other benefits as
determined by the Company.

          D.  Certain Definitions.
              -------------------

          Change in Control.  A "Change in Control" shall be deemed to have
occurred (i) on the date that any person or group deemed a person under Sections
3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, other than the
Company, in a transaction or series of transactions, has become the beneficial
owner, directly or indirectly (with beneficial ownership as determined as
provided in Rule 13d-3, or any successor rule under such Act), of 20% or more of
the outstanding voting securities of the Company; or (ii) on the date on which
one third or more of the members of the Board of Directors shall consist of
persons other than Current Directors (for these purposes, a "Current Director"

Current Director who has been approved by a majority of the Current Directors
then on the Board, and any other person who has been approved by a majority of
the Current Directors then

                                       15

on the Board); or (iii) on the date of approval of (x) the merger or
consolidation of the Company with another corporation where the shareholders of
the Company, immediately prior to the merger or consolidation, would not
beneficially own, immediately after the merger or consolidation, shares
entitling such shareholders to 50% or more of all votes (without consideration
of the rights of any class of stock to elect directors by a separate class vote)
to which all shareholders of the corporation would be entitled in the election
of directors or where the members of the Board of Directors of the Company,
immediately prior to the merger or consolidation, would not immediately after
the merger or consolidation, constitute a majority of the Board of Directors of
the corporation issuing cash or securities in the merger or consolidation or (y)
on the date of approval of the sale or other disposition of all or substantially
all the assets of the Company.

          Termination for Cause.  The Company shall have the right to terminate
the services of Executive without further liability or obligations to Executive
in the event that there is Cause.  For purposes of this Agreement, "Cause" is

of, or plea of nolo contendere to, a felony, (iii) Executive's gross misconduct,
(iv) Executive's continuing violations of his employment duties after Executive

Executive has not substantially performed his duties and provides Executive
thirty (30) business days to cure any such violation(s), or (v) Executive's
violation or

                                       16
<PAGE>

this Agreement. Termination for Cause under Section (v) above shall not occur
until Executive has been provided written notice of such violation or breach and
until Executive has been provided thirty (30) business days to cure any such
violation or breach.

          Good Reason.  Good Reason shall mean the occurrence or existence of
any of the following with respect to Executive:  (i) Executive's annual rate of
salary is reduced from the annual rate then currently in effect or Executive's
other employee benefits are in the aggregate materially reduced from those then
currently in effect, or (ii) Executive's place of employment is moved more than
50 miles from Eugene, Oregon or Portland, Oregon, except that Executive's place
of employment may be moved from Portland, Oregon to Eugene, Oregon, or to any
place in between such locations,  or (iii) Executive's title is changed or he is
assigned duties that are materially inconsistent with the duties then currently
performed by Executive.  In the event of the relocation from Portland, Oregon to
Eugene, Oregon pursuant to (ii) above, the Company shall reimburse Executive
either for reasonable commuting expenses or for reasonable relocation expenses,
as defined in Section 6 above, at the election of Executive.

          Before Executive may terminate his employment for Good Reason,
Executive must notify the Company in writing of his intention to terminate and
the Company shall have 15 days after receiving such written notice to remedy the
situation, if possible.

          E.  Release.  Notwithstanding the foregoing, PSC may condition the

the election to exercise the Option and the number of shares with respect to
which the Option is being exercised.  The written notice shall be signed by the
person exercising the Option, shall be delivered to the Company at its principal
executive office, and shall be accompanied by payment equal to the full purchase
price for the shares which are exercised.  The purchase price of each share
purchased upon exercise of the Option shall be paid in full (a) in cash at the
time of exercise, (b) with common shares of the Company owned by the Optionee,
(c) by delivering to the Company

                                       2

(i) irrevocable instructions to deliver the stock certificates representing the
shares for which the Option is being exercised, directly to a broker, and (ii)
instructions to the broker to sell such shares and promptly deliver to the
Company the portion of the proceeds equal to the total purchase price, or (d) in
any combination thereof.  For purposes of making payment in common shares of the
Company, such shares shall be valued at their fair market value (as defined in
the Plan) on the date of exercise of the Option and shall have been held by the
Optionee for a period of at least six (6) months.  Such notice shall be given on
the form attached hereto and designated as Exhibit A.  In the event the Option
shall be exercised pursuant to Section 7(b) hereof by any person or persons
other than the Optionee, such notice shall be accompanied by appropriate proof
of the right of such person or persons to exercise the Option.

          6.  Non-Transferability of Option Rights.  This Option shall not be
              ------------------------------------
transferable by the Optionee except by will or by the laws of descent and
distribution.  During the life of the Optionee, the Option shall be exercisable
only by Optionee.  More particularly (but without limiting the generality of the
foregoing), the Option may not be assigned, transferred (except as provided
above), pledged, or hypothecated in any way, shall not be assignable by
operation of law, and shall not be subject to execution, attachment or similar
process.  Any attempted assignment, transfer, pledge, hypothecation, or other
disposition of the Option contrary to the provisions hereof, and the levy of any
execution, attachment, or similar process upon the Option, shall be null and
void and without effect.

          7.  Termination of Employment or Death
              ----------------------------------

              (a) If the employment of Optionee shall terminate for Cause (as
defined in the Employment Agreement), this Option shall cease to be exercisable
on the date of such termination.

                                       3
<PAGE>

              (b) Notwithstanding Section 4 of this Agreement, if Optionee's
employment shall terminate for any reason other than Cause, including, but not
limited to, death, Disability, Change in Control (as defined in the Employment
Agreement), or Good Reason (as defined in the Employment Agreement), or in the
event of any tender offer or exchange offer (other than an offer by the Company)
for the Company's common shares, or a dissolution or liquidation of the Company,
or a merger or consolidation or similar transaction in which the Company is not
the surviving company, or a sale, exchange or other disposition of all or
substantially all of the Company assets, Optionee shall automatically become
fully vested in this Option and this Option shall become fully exercisable and
may be exercised until the expiration date specified in Section 4(c).  In the
case of death, exercise may be made by the Optionee's Designated Beneficiary (as
defined in the Plan).

          8.  General Restriction.  This Option shall be subject to the
              -------------------
requirement that if at any time the Board of Directors in its discretion shall
determine that the listing, registration or qualification of the shares subject
to such Option on any securities exchange or under any state or federal law, or
the consent or approval of any government regulatory body, is necessary or
desirable as a condition of, or in connection with, the granting of such Option
or the issuance or purchase of shares thereunder, such Option may not be
exercised in whole or in part unless such listing, registration, qualification,
consent or approval shall have been effected or obtained free of any conditions
not reasonably acceptable to the Board of Directors.

          9.  Option Adjustments.  In the event of a stock dividend, stock split
              ------------------
or other change in corporate structure or capitalization affecting the common
shares or any other transaction (including, without limitation, an extraordinary
cash dividend) which, in the determination of the Compensation Committee (the
"Committee") of the Board of Directors, affects the common

                                       4
<PAGE>

shares such that an adjustment is required in order to preserve the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall equitably adjust any or all of (i) the number and kind of shares
subject to this Option, and (ii) the purchase price with respect to the
foregoing, provided that the number of shares subject to this Option shall
always be a whole number.

          10.  Amendment to this Option Agreement.  The Committee may modify or
               ----------------------------------
amend this Option if it determines, in its sole discretion, that amendment is
necessary or advisable in the light of any addition to or change in the Internal
Revenue Code or in the regulations issued thereunder, or any federal or state
securities laws or other law or regulation, which change occurs after the Date
of Grant of this Option and by its terms applies to this Option.  No amendment
of this Option, however, may, without the consent of the Optionee, make any
changes which would adversely effect the rights of such Optionee.

          11.  Disqualifying Disposition.  In the event that Optionee shall sell
               -------------------------
or transfer any common shares acquired upon the exercise of the ISO portion of
this Option prior to the later of (a) two (2) years from the Date of Grant or
(b) one (1) year from the date of exercise of the Option, Optionee agrees to so
advise the Company immediately and to promptly pay to the Company the amount of
any Federal, State or local taxes that may be required.

          12.  Right of Employment.  Nothing contained herein shall confer upon
               -------------------
the Optionee any right to be continued in the employment of the Company or
interfere in any way with the right of the Company to terminate Optionee's
employment at any time for any cause.

          13.  Definitions.  Any terms or provisions used herein which are
               -----------
defined in Sections 421, 422 or 425 of the Internal Revenue Code of 1986, as
amended, or the regulations thereunder

                                       5
<PAGE>

or corresponding provisions of subsequent laws and regulations in effect at the
time this Option is granted shall have the meanings as therein defined.

          14.  Notices.  Notices hereunder shall be in writing and if to the
               -------
Company shall be delivered personally to the Secretary of the Company or mailed
to its principal office, 959 Terry Street, Eugene, Oregon 97402, addressed to
the attention of the Secretary, and, if to the Optionee, shall be delivered
personally or mailed to the Optionee at Optionee's address as the same appears
on the records of the Company.

          15.  Interpretations of this Agreement.  All decisions and
               ---------------------------------
interpretations made by the Committee with regard to any question arising
hereunder or under the Plan shall be binding and conclusive on the Company and
the Optionee.  The Option granted hereunder, and the common shares which may be
issued upon exercise thereof, are subject to the provisions of the Plan.  In the
event there is any inconsistency between the provisions of this Agreement and
those of the Plan, the provisions of the Plan shall govern.

          16.  Successors and Assigns.  This Agreement shall bind and inure to
               ----------------------
the benefit of the parties hereto and the successors and assigns of the Company
and, to the extent provided in Section 7, to the personal representatives,
legatees and heirs of the Optionee.

                    IN WITNESS WHEREOF, the Company has caused this Option
Agreement to be executed on the day and year first above written.
