                                    ARTICLE I

or more global certificates (each, a "Global Warrant Certificate").] [If
Securities and Warrants are to be offered together and in definitive form - Each
Warrant Certificate included in such a unit shall evidence [__________] Warrants
for each [$_____ principal amount of] [__________] Offered Securities included

- Each Warrant Certificate shall evidence [__________] Warrants.]

<PAGE>

Certificate shall be printed, lithographed, typewritten, mimeographed or
engraved on steel engraved borders or otherwise reproduced in any other manner
as may be approved by the officers executing the same (such execution to be
conclusive evidence of such approval) and may have such letters, numbers or
other marks of identification or designation and such legends or endorsements
printed, lithographed or engraved thereon as the officers of the Company
executing the same may approve (such execution to be conclusive evidence of such
approval) and as are not inconsistent with the provisions of this Agreement, or
as may be required to comply with any law or with any rule or regulation made
pursuant thereto, or with any regulation of any stock exchange on which the
Warrants [If Securities and Warrants are to be offered together - , the Offered
Securities] or the Warrant Securities may be listed, or to conform to usage.
Each Warrant Certificate shall be signed on behalf of the Company by its
Chairman of the Board, President or any Executive or Senior Vice President. The
signature of any such officer on any Warrant Certificate may be manual or
facsimile. Each Warrant Certificate, when so signed on behalf of the Company,
shall be delivered to the Warrant Agent together with an order for the
countersignature and delivery of such Warrants.

         (c)      The Warrant Agent shall, upon receipt of any Warrant

Certificate and deliver such Warrant Certificate to or upon the order of the
Company. Each Warrant Certificate shall be dated the date of its
countersignature.

         (d)      No Warrant Certificate shall be entitled to any benefit under
this Agreement or be valid or obligatory for any purpose, and no Warrant
evidenced thereby may be exercised, unless such Warrant Certificate has been
countersigned by the manual signature of the Warrant Agent. Such signature by
the Warrant Agent upon any Warrant Certificate executed by the Company shall be
conclusive evidence that such Warrant Certificate has been duly issued under the
terms of this Agreement.

         (e)      If any officer of the Company who has signed any Warrant
Certificate either manually or by facsimile signature shall cease to be such
officer before such Warrant Certificate shall have been countersigned and
delivered by the Warrant Agent, such Warrant Certificate nevertheless may be
countersigned and delivered as though the person who signed such Warrant
Certificate had not ceased to be such officer of the Company; and any Warrant
Certificate may be signed on behalf of the Company by such persons as, at the
actual date of the execution of such Warrant Certificate, shall be the proper
officers of the Company as specified in this Section 1.02, regardless of whether
at the date of the execution of this Agreement any such person was such officer.

         (f)      The Holders shall [If Warrants are to be issued in Book-Entry
form - , except as stated below with respect to Warrants evidenced by a Global
Warrant Certificate,] be entitled to receive Warrants in physical, certificated

Certificate may be exchanged for a new Global Warrant Certificate, or one or
more new Global Warrant Certificates may be issued, to reflect the issuance by
the Company of additional

                                       3

<PAGE>

Warrants. To effect such an exchange, the Company shall deliver to the Warrant
Agent one or more new Global Warrant Certificates duly executed on behalf of the
Company as provided in Section 1.02. The Warrant Agent shall authenticate each
new Global Warrant Certificate as provided in Section 1.02 and shall deliver
each new Global Warrant Certificate to the Depository. The Warrant Agent shall
cancel each Global Warrant Certificate delivered to it by the Depository in
exchange therefor, if any.]

         SECTION 1.03.  Transfer of Warrants.

         (a)      [If Warrants are to be issued in Book-Entry form - [All] [A
portion] of the Warrants shall initially be represented by one or more Global
Warrant Certificates deposited with [the Depository Trust Company] (the
"Depository") and registered in the name of [Cede & Co.], a nominee of the
Depository. The Depository, or such other entity as is agreed to by the
Depository, may hold each Global Warrant Certificate as custodian for
Depository. Except as provided for in Section 1.03(b) hereof, no person
acquiring Warrants traded on any securities exchange with book-entry settlement
through the Depository shall receive or be entitled to receive physical delivery
of definitive Warrant Certificates evidencing such Warrants. Ownership of
beneficial interests in the Warrants shall be shown on, and the transfer of such
ownership shall be effected through, records maintained by (i) the Depository or
its nominee for each Global Warrant Certificate, or (ii) institutions that have
accounts with the Depository (such institution, with respect to a Warrant in its
account, a "Participant").]

         (b)      [If Warrants are to be issued in Book-Entry form - If the
Depository subsequently ceases to make its book-entry settlement system
available for the Warrants, the Company may instruct the Warrant Agent regarding
making other arrangements for book-entry settlement. In the event that the
receipts are not eligible for, or it is no longer necessary to have the Warrants
available in, book-entry form, the Warrant Agent shall provide written
instructions to the Depository to deliver to the Warrant Agent for cancellation
each Global Warrant Certificate, and the Company shall instruct the Warrant
Agent to deliver to the Depository definitive Warrant Certificates in physical
form evidencing such Warrants. Such definitive Warrant Certificates shall be in
the form annexed hereto as Exhibit A with appropriate insertions, modifications
and omissions, as provided above.]

         (c)      [If Securities and Warrants are to be offered together - [If
Warrants are not immediately detachable - Prior to the Detachment Date,]
Warrants may be transferred or exchanged only together with the Offered Security
to which such Warrant is attached, and only for the purpose of effecting, or in
conjunction with, a transfer or exchange of such Offered Security. Furthermore,
[If Warrants are not immediately detachable - on or prior to the Detachment
Date,] each transfer of an Offered Security on the register relating to such
Offered Securities shall operate also to transfer the Warrants to which such
Offered Security was initially attached. [If Warrants are not immediately
detachable - From and after the Detachment Date, the above provisions shall be
of no further force and effect.]

                                       4

<PAGE>

         (d)      A Warrant Certificate may be transferred at the option of the
Holder thereof upon surrender of such Warrant Certificate at the corporate trust
office of the Warrant Agent, properly endorsed or accompanied by appropriate
instruments of transfer and written instructions for transfer, all in form
satisfactory to the Company and the Warrant Agent [If Warrants are to be issued
in Book-Entry form - ; provided, however, that except as otherwise provided
herein or in any Global Warrant Certificate, each Global Warrant Certificate may
be transferred only in whole and only to the Depository, to another nominee of
the Depository, to a successor depository, or to a nominee of a successor
depository]. Upon any such registration of transfer, the Company shall execute,
and the Warrant Agent shall countersign and deliver, as provided in Section
1.02, in the name of the designated transferee a new Warrant Certificate or
Warrant Certificates of any authorized denomination evidencing in the aggregate
a like number of unexercised Warrants.

         (e)      [If Warrants are not immediately detachable - After the
Detachment Date,] Upon surrender at the corporate office of the Warrant Agent,
properly endorsed or accompanied by appropriate instruments of transfer and
written instructions for such exchange, all in form satisfactory to the Company
and the Warrant Agent, one or more Warrant Certificates may be exchanged for one
or more Warrant Certificates in any other authorized denominations; provided
that such new Warrant Certificate(s) evidence the same aggregate number of
Warrants as the Warrant Certificate(s) so surrendered. Upon any such surrender
for exchange, the Company shall execute, and the Warrant Agent shall countersign
and deliver, as provided in Section 1.02, in the name of the Holder of such
Warrant Certificates, the new Warrant Certificates.

         (f)      The Warrant Agent shall keep, at its corporate trust office,
books in which, subject to such reasonable regulations as it may prescribe, it
shall register Warrant Certificates in accordance with Section 1.02 and
transfers, exchanges, exercises and cancellations of outstanding Warrant
Certificates. Whenever any Warrant Certificates are surrendered for transfer or
exchange in accordance with this Section 1.03, an authorized officer of the
Warrant Agent shall manually countersign and deliver the Warrant Certificates
which the Holder making the transfer or exchange is entitled to receive.

         (g)      No service charge shall be made for any transfer or exchange
of Warrant Certificates, but the Company may require payment of a sum sufficient
to cover any stamp or other tax or other governmental charge that may be imposed
in connection with any such transfer or exchange.

         SECTION 1.04. Lost, Stolen, Mutilated or Destroyed Warrant
Certificates. Upon receipt by the Company and the Warrant Agent of evidence
satisfactory to them of the ownership of and the loss, theft, destruction or
mutilation of any Warrant Certificate and of indemnity satisfactory to them and,
in the case of mutilation, upon surrender of such Warrant Certificate to the
Warrant Agent for cancellation, then, in the absence of notice to the Company or
the Warrant Agent that such Warrant Certificate has been acquired by a bona fide
purchaser, the Company shall execute, and an authorized officer of the

                                       5

<PAGE>

Warrant Agent shall manually countersign and deliver, in exchange for or in lieu
of the lost, stolen, destroyed or mutilated Warrant Certificate, a new Warrant
Certificate of the same tenor and for a like number of Warrants. No service
charge shall be made for any replacement of Warrant Certificates, but the
Company may require the payment of a sum sufficient to cover any stamp or other
tax or other governmental charge that may be imposed in connection with any such
exchange. To the extent permitted under applicable law, the provisions of this
Section 1.04 are exclusive with respect to the replacement of mutilated, lost,
stolen or destroyed Warrant Certificates and shall preclude any and all other
rights or remedies.

         SECTION 1.05. Cancellation of Warrant Certificates. Any Warrant
Certificate surrendered to the Warrant Agent for transfer, exchange or exercise
of the Warrants evidenced thereby shall be promptly canceled by the Warrant
Agent and shall not be reissued and, except as expressly permitted by this
Agreement, no Warrant Certificate shall be issued hereunder in lieu thereof. The
Warrant Agent shall deliver to the Company from time to time or otherwise
dispose of canceled Warrant Certificates in a manner satisfactory to the
Company. Any Warrant Certificate surrendered to the Company for transfer,
exchange or exercise of the Warrants evidenced thereby shall be promptly
delivered to the Warrant Agent and such transfer, exchange or exercise shall not
be effective until such Warrant Certificate has been received by the Warrant
Agent.

         SECTION 1.06. Treatment of Holders [If Warrants are to be Issued in
Book-Entry Form - and Beneficial Owners] of Warrant Certificates. (a) The term
"Holder", as used herein, shall mean any person in whose name at the time any
Warrant Certificate shall be registered upon the books to be maintained by the
Warrant Agent for that purpose [If Securities and Warrants that are not
immediately detachable are offered - or, prior to the Detachment Date, the
person in whose name the Offered Security to which such Warrant Certificate was
initially attached is registered upon the register relating to such Offered
Securities. At all times prior to the Detachment Date, the Company will, or will
cause the registrar of the Offered Securities to, make available to the Warrant
Agent such information as to holders of the Offered Securities as may be
necessary to keep the Warrant Agent's records current]. [If Warrants are to be
issued in Book-Entry form - The Holder of each Global Warrant Certificate shall
initially be [Cede & Co.], a nominee of the Depository.]

         (a)      [If Warrants are to be issued in Book-Entry Form - The term
"Beneficial Owner" as used herein shall mean any person in whose name ownership
of beneficial interests in Warrants evidenced by a Global Warrant Certificate is
recorded in the records maintained by the Depository or its nominee, or by a
Participant [If Securities and Warrants that are not immediately detachable are
offered - , or, prior to the Detachment Date, the person in whose name the
Offered Security to which such Warrant Certificate was initially attached is
registered upon the register relating to such Offered Securities].]

         (b)      Every Holder [If Warrants are to be issued in Book-Entry form
- and every Beneficial Owner] consents and agrees with the Company, the Warrant
Agent and with every subsequent Holder [If Warrants are to be issued in
Book-Entry form - and

                                       6

<PAGE>

Beneficial Owner] that until the Warrant Certificate is transferred on the books
of the Warrant Agent, the Company and the Warrant Agent may treat the registered
Holder of such Warrant Certificate as the absolute owner of the Warrants
evidenced thereby for any purpose and as the person entitled to exercise the
rights attaching to the Warrants evidenced thereby, any notice to the contrary
notwithstanding.

                                   ARTICLE II

         SECTION 2.01. Exercise Price. The exercise price of each Warrant shall
be $________ (the "Exercise Price") [modify as appropriate to reflect terms of
offered Warrants].

         SECTION 2.02. Duration of Warrants. [Subject to the limitations set
forth herein,] Each Warrant may be exercised in whole but not in part [Unless
Warrants may be exercised on only one date: on any Business Day (as defined
below) occurring during the period (the "Exercise Period") commencing on [its
date of issuance] [________ __, ___] and ending at 5:00 P.M., New York time,] on
__________ , ____ (the "Expiration Date"). Each Warrant remaining unexercised
after 5:00 P.M., New York time, on the Expiration Date shall become void, and
all rights of the Holder under this Agreement shall cease.

         As used herein, the term "Business Day" means any day which is not a
Saturday or Sunday and is not a legal holiday or a day on which banking
institutions generally are authorized or obligated by law or regulation to close
in New York.

         SECTION 2.03.  Exercise of Warrants.

         (a)      A Holder may exercise a Warrant by delivering, not later than
5:00 P.M., New York time, on [Unless Warrants may be exercised on only one date:
any Business Day during the Exercise Period (the "Exercise Date")] [If Warrants
may be exercised on only one date - the Expiration Date] to the Warrant Agent at
its corporate trust department (i) the Warrant Certificate evidencing the
Warrants to be exercised, [If Warrants are to be issued in Book-Entry form -
and, in the case of a Global Warrant Certificate, the Warrants to be exercised
(the "Book-Entry Warrants") free on the records of the Depository to an account
of the Warrant Agent at the Depository designated for such purpose in writing by
the Warrant Agent to the Depository from time to time,] (ii) an election to
purchase the Warrant Securities ("Election to Purchase"), properly completed and
executed by the Holder on the reverse of the Warrant Certificate [If Warrants

Certificate, properly executed by the Participant and substantially in the form
included on the reverse of each Warrant Certificate,] and (iii) the Exercise
Price for each Warrant to be exercised in lawful money of the United States of

<PAGE>

received by the Warrant Agent after 5:00 P.M., New York time, on [Unless
Warrants may be exercised on only one date: the specified Exercise Date, the
Warrants will be deemed to be received and exercised on the Business Day next
succeeding the Exercise Date. It the date specified as the Exercise Date is not
a Business Day, the Warrants will be deemed to be received and exercised on the
next succeeding day which is a Business Day. If the Warrants are received or
deemed to be received after] the Expiration Date, the exercise thereof will be
null and void and any funds delivered to the Warrant Agent will be returned to
the Holder [If Warrants are to be issued in Book-Entry form - or Participant, as
the case may be,] as soon as practicable. In no event will interest accrue on
funds deposited with the Warrant Agent in respect of an exercise or attempted
exercise of Warrants. The validity of any exercise of Warrants will be
determined by the Warrant Agent in its sole discretion and such determination
will be final and binding upon the Holder and the Company. Neither the Company
nor the Warrant Agent shall have any obligation to inform a Holder of the
invalidity of any exercise of Warrants. The Warrant Agent shall deposit all
funds received by it in payment of the Exercise Price in the account of the
Company maintained with the Warrant Agent for such purpose and shall advise the
Company by telephone at the end of each day on which funds for the exercise of
the Warrants are received of the amount so deposited to its account. The Warrant
Agent shall promptly confirm such telephonic advice to the Company in writing.
(b) The Warrant Agent shall, by 11:00 A.M. on the Business Day following the
[Unless Warrants may be exercised on only one date: Exercise Date of any
Warrant] [If Warrants may be exercised on only one date - Expiration Date],

transfer agent and registrar in respect of] the Warrant Securities issuable upon
such exercise as to the number of Warrants exercised in accordance with the
terms and conditions of this Agreement, the instructions of each Holder [If
Warrants are to be issued in Book-entry Form - or Participant, as the case may
be,] with respect to delivery of the Warrant Securities issuable upon such
exercise, and the delivery of definitive Warrant Certificates [If Warrants are
to be issued in Book-Entry form - or one or more Global Warrant Certificates, as
appropriate,] evidencing the balance, if any, of the Warrants remaining after
such exercise, and such other information as the Company or such [Trustee]
[transfer agent and registrar] shall reasonably require.

         (c)      The Company shall, by 5:00 P.M., New York time, on the third
Business Day next succeeding the [Unless Warrants may be exercised on only one
date: Exercise Date of any Warrant] [If Warrants may be exercised on only one
date - Expiration Date], execute, issue and deliver to the Warrant Agent,
[pursuant to the Indenture applicable to the Warrant Securities, the Warrant
Securities, duly authenticated by the Trustee of such Indenture and in
authorized denominations] [the Warrant Securities] to which such Holder is
entitled, in fully registered form, registered in such name or names as may be
directed by such Holder [If Warrants are to be issued in Book-Entry form - or
the Participant, as the case may be]. Upon receipt of such Warrant Securities,
the Warrant Agent shall, by 5:00 P.M., New York time, on the fifth Business Day
next succeeding [Unless Warrants may be exercised on only one date: such
Exercise Date] [If Warrants may be exercised on only one date - the Expiration
Date], transmit such Warrant Securities, to or upon the order of the Holder [If
Warrants are to be issued in Book-Entry

form - or Participant, as the case may be,] together with, or preceded by the
prospectus referred to in Section 5.06 hereof. The Company agrees that it will
provide such information and documents to the Warrant Agent as may be necessary
for the Warrant Agent to fulfill its obligations hereunder.

         (d)      The accrual of [interest] [dividends], if any, on the Warrant
Securities issued upon the valid exercise of any Warrant will be governed by the
terms of the applicable [Indenture] [articles of amendment] and such Warrant
Securities. From and after the issuance of such Warrant Securities, the former
Holder of the Warrants exercised will be entitled to the benefits of the
[Indenture] [articles of amendment] under which such Warrant Securities are
issued and such former Holder's right to receive payments of [principal of (and
premium, if any) and interest, if any, on] [dividends and any other amounts
payable in respect of] the Warrant Securities shall be governed by, and shall be
subject to, the terms and provisions of such [Indenture] [articles of amendment]
and the Warrant Securities.

         Warrants may be exercised only in whole numbers of Warrants. [Unless
Warrants may be exercised on only one date: If fewer than all of the Warrants
evidenced by a Warrant Certificate are exercised, a new Warrant Certificate for
the number of Warrants remaining unexercised shall be executed by the Company
and countersigned by the Warrant Agent as provided in Section 1.02 hereof, and
delivered to the Holder at the address specified on the books of the Warrant
Agent or as otherwise specified by such Holder.]

         (e)      The Company shall not be required to pay any stamp or other
tax or other governmental charge required to be paid in connection with any
transfer involved in the issue of the Warrant Securities; and in the event that
any such transfer is involved, the Company shall not be required to issue or
deliver any Warrant Securities until such tax or other charge shall have been
paid or it has been established to the Company's satisfaction that no such tax
or other charge is due.

         [If Warrants for Common Stock are offered - SECTION 2.04. Adjustment
Under Certain Circumstances. The Exercise Price and the number of Warrant
Securities purchasable upon the exercise of each Warrant shall be subject to
adjustment upon (i) the issuance of a stock dividend to the holders of the
outstanding shares of Warrant Securities or a combination, subdivision or
reclassification of the Warrant Securities; (ii) the issuance of rights,
warrants or options to all holders of the Warrant Securities entitling the
holders thereof to purchase Warrant Securities for an aggregate consideration
per share less than the current market price per share of the Warrant
Securities; or (iii) any distribution by the Company to the holders of the
Warrant Securities of evidences of indebtedness of the Company or of assets
(excluding cash dividends or distributions payable out of consolidated earnings
and earned surplus and dividends or distributions referred to in (i) above);
provided that no such adjustment in the number of Warrant Securities purchasable
upon exercise of the Warrants will be required until cumulative adjustments
require an adjustment of at least 1% of such number. No fractional shares will
be issued upon exercise of Warrants, but the Company will pay the cash value of
any

Certificates, as may be appropriate.
