WASTE INDUSTRIES INC., a Delaware corporation (the "COMPANY") and ___________,
a [corporation] [national banking association] organized and existing under the
laws of __________ and having a corporate trust office in ________, as warrant

     WHEREAS, the Company has entered into an indenture dated as of [______ (the
"SENIOR INDENTURE"), with __________, as trustee (such trustee, and any
successors to such trustee, herein called the "SENIOR TRUSTEE"), providing for
the issuance from time to time of its unsubordinated debt securities, to be

                                    ARTICLE 1
     ISSUANCE OF WARRANTS AND EXECUTION AND DELIVERY OF WARRANT CERTIFICATES

     1.1 ISSUANCE OF WARRANTS. [If Warrants alone--Upon issuance, each Warrant
Certificate shall evidence one or more Warrants.] [If Other Securities and
Warrants--Warrant Certificates shall be [initially] issued in connection with
the issuance of the Other Securities [but shall be separately transferable on
and after ____________________ (the "DETACHABLE DATE")] [and shall not be
separately transferable] and each Warrant Certificate shall evidence one or more
Warrants.] Each Warrant evidenced thereby shall represent the right, subject to
the provisions contained herein and therein, to purchase one Warrant Debt
Security. [If Other Securities and Warrants--Warrant Certificates shall be
initially issued in units with the Other Securities and each Warrant Certificate
included in such a unit shall evidence ________ Warrants for each [$________
principal amount] [_______ shares] of Other Securities included in such unit.].

     1.2 EXECUTION AND DELIVERY OF WARRANT CERTIFICATES. Each Warrant
Certificate, whenever issued, shall be in registered form substantially in the
form set forth in Exhibit A hereto, shall be dated the date of its
countersignature by the Warrant Agent 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 (execution thereof 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 rule or regulation of any
securities exchange on which the Warrants may be listed, or to conform to usage.
The Warrant Certificates shall be signed on behalf of the Company by any of its
present or future chief executive officers, presidents, senior vice presidents,
vice presidents, chief financial officers, chief legal officers, treasurers,
assistant treasurers, controllers, assistant controllers, secretaries or
assistant secretaries under its corporate seal reproduced thereon. Such
signatures may be manual or facsimile signatures of such authorized officers and
may be imprinted or otherwise reproduced on the Warrant Certificates. The seal
of the Company may be in the form of a facsimile thereof and may be impressed,
affixed, imprinted or otherwise reproduced on the Warrant Certificates.

     No Warrant Certificate shall be valid for any purpose, and no Warrant
evidenced thereby shall be exercisable, until 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 the Warrant Certificate so countersigned has been duly
issued hereunder.

                                        3

<PAGE>

     In case any officer of the Company who shall have signed any of the Warrant
Certificates either manually or by facsimile signature shall cease to be such
officer before the Warrant Certificates so signed shall have been countersigned
and delivered by the Warrant Agent, such Warrant Certificates may be
countersigned and delivered notwithstanding that the person who signed Warrant
Certificates 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, although at the date of the execution of this Agreement
any such person was not such officer.

     The term "holder" or "holder of a Warrant Certificate" 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 Other Securities and Warrants are not immediately detachable--or upon the
registration of the Other Securities prior to the Detachable Date. Prior to the
Detachable Date, the Company will, or will cause the registrar of the Other
Securities to, make available at all times to the Warrant Agent such information
as to holders of the Other Securities as may be necessary to keep the Warrant
Agent's records up to date].

     1.3 ISSUANCE OF WARRANT CERTIFICATES. Warrant Certificates evidencing the
right to purchase Warrant Debt Securities may be executed by the Company and
delivered to the Warrant Agent upon the execution of this Warrant Agreement or
from time to time thereafter. The Warrant Agent shall, upon receipt of Warrant
Certificates duly executed on behalf of the Company, countersign such Warrant
Certificates and shall deliver such Warrant Certificates to or upon the order of
the Company.

                                    ARTICLE 2
                WARRANT PRICE, DURATION AND EXERCISE OF WARRANTS

     2.1 WARRANT PRICE. During the period specified in Section 2.2, each Warrant
shall, subject to the terms of this Warrant Agreement and the applicable Warrant
Certificate, entitle the holder thereof, to purchase the principal amount of
Warrant Debt Securities specified in the applicable Warrant Certificate at an
exercise price of _____% of the principal amount thereof [plus accrued
amortization, if any, of the original issue discount of the Warrant Debt
Securities] [plus accrued interest, if any, from the most recent date from which
interest shall have been paid on the Warrant Debt Securities or, if no interest
shall have been paid on the Warrant Debt Securities, from the date of their
initial issuance.] [The original issue discount ($___________ for each $1,000
principal amount of Warrant Debt Securities) will be amortized at a _____%
annual rate, computed on a[n] [semi-] annual basis [using a 360-day year
consisting of twelve 30-day months].] Such purchase price for the Warrant Debt
Securities is referred to in this Agreement as the "WARRANT PRICE."

                                        4

     2.2 DURATION OF WARRANTS. Each Warrant may be exercised in whole or in part
at any time, as specified herein, on or after [the date thereof] [_____] and at
or before [_____] p.m., [City] time, on _____ or such later date as the Company
may designate by notice to the Warrant Agent and the holders of Warrant
Certificates mailed to their addresses as set forth in the record books of the
Warrant Agent (the "EXPIRATION DATE"). Each Warrant not exercised at or before
[_____] p.m., [City] time, on the Expiration Date shall become void, and all
rights of the holder of the Warrant Certificate evidencing such Warrant under
this Agreement shall cease.

     2.3 EXERCISE OF WARRANTS.

     (a) During the period specified in Section 2.2, the Warrants may be
exercised to purchase a whole number of Warrant Debt Securities in registered
form by providing certain information as set forth on the reverse side of the
Warrant Certificate and by paying in full, in lawful money of the United States
of America, [in cash or by certified check or official bank check in New York
Clearing House funds] [by bank wire transfer in immediately available funds] the
Warrant Price for each Warrant Debt Security with respect to which a Warrant is
being exercised to the Warrant Agent at its corporate trust office, provided
that such exercise is subject to receipt within five business days of such
payment by the Warrant Agent of the Warrant Certificate with the form of
election to purchase Warrant Debt Securities set forth on the reverse side of
the Warrant Certificate properly completed and duly executed. The date on which
payment in full of the Warrant Price is received by the Warrant Agent shall,
subject to receipt of the Warrant Certificate as aforesaid, be deemed to be the
date on which the Warrant is exercised; provided, however, that if, at the date
of receipt of such Warrant Certificates and payment in full of the Warrant
Price, the transfer books for the Warrant Debt Securities purchasable upon the
exercise of such Warrants shall be closed, no such receipt of such Warrant
Certificates and no such payment of such Warrant Price shall be effective to
constitute the person so designated to be named as the holder of record of such
Warrant Debt Securities on such date, but shall be effective to constitute such
person as the holder of record of such Warrant Debt Securities for all purposes
at the opening of business on the next succeeding day on which the transfer
books for the Warrant Debt Securities purchasable upon the exercise of such
Warrants shall be opened, and the certificates for the Warrant Debt Securities
in respect of which such Warrants are then exercised shall be issuable as of the
date on such next succeeding day on which the transfer books shall next be
opened, and until such date the Company shall be under no duty to deliver any
certificate for such Warrant Debt Securities. The Warrant Agent shall deposit
all funds received by it in payment of the Warrant Price in an account of the
Company maintained with it and shall advise the Company by telephone at the end
of each day on which a payment for the exercise of Warrants is received of the
amount so deposited to its account. The Warrant Agent shall promptly confirm
such telephone advice to the Company in writing.

                                        5

<PAGE>

     (b) The Warrant Agent shall, from time to time, as promptly as practicable,
advise the Company of (i) the number of Warrant Debt Securities with respect to
which Warrants were exercised, (ii) the instructions of each holder of the
Warrant Certificates evidencing such Warrants with respect to delivery of the
Warrant Debt Securities to which such holder is entitled upon such exercise,
(iii) delivery of Warrant Certificates evidencing the balance, if any, of the
Warrants for the remaining Warrant Debt Securities after such exercise, and (iv)
such other information as the Company or the [Senior] [Subordinated] Trustee
shall reasonably require.

     (c) As soon as practicable after the exercise of any Warrant, the Company
shall issue, pursuant to the Indenture, in authorized denominations, to or upon
the order of the holder of the Warrant Certificate evidencing such Warrant, the
Warrant Debt 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
fewer than all of the Warrants evidenced by such Warrant Certificate were
exercised, the Company shall execute, and an authorized officer of the Warrant
Agent shall manually countersign and deliver, a new Warrant Certificate
evidencing Warrants for the number of Warrant Debt Securities remaining
unexercised.

     (d) 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 Debt Securities, and in the event that any
such transfer is involved, the Company shall not be required to issue or deliver
any Warrant Debt 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.

                                    ARTICLE 3
     OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT CERTIFICATES

     3.1 NO RIGHTS AS HOLDERS OF WARRANT DEBT SECURITIES CONFERRED BY WARRANTS
OR WARRANT CERTIFICATES. No Warrant Certificate or Warrant evidenced thereby
shall entitle the holder thereof to any of the rights of a holder of Warrant
Debt Securities, including, without limitation, the right to receive the payment
of principal of (or premium, if any) or interest, if any, on the Warrant Debt
Securities or to enforce any of the covenants in the Indenture.

                                        6

<PAGE>

     3.2 LOST, STOLEN, MUTILATED OR DESTROYED WARRANT CERTIFICATES. Upon receipt
by the Warrant Agent of evidence reasonably satisfactory to it and the Company
of the ownership of and the loss, theft, destruction or mutilation of any
Warrant Certificate and/or indemnity reasonably satisfactory to the Warrant
Agent and the Company and, in the case of mutilation, upon surrender of the
mutilated 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 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 evidencing Warrants for a like principal amount of Warrant Debt
Securities. Upon the issuance of any new Warrant Certificate under this Section
3.2, 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 Warrant Agent) in connection
therewith. Every substitute Warrant Certificate executed and delivered pursuant
to this Section 3.2 in lieu of any lost, stolen or destroyed Warrant Certificate
shall represent an additional contractual obligation of the Company, whether or
not the lost, stolen or destroyed Warrant Certificate shall be at any time
enforceable by anyone, and shall be entitled to the benefits of this Agreement
equally and proportionately with any and all other Warrant Certificates duly
executed and delivered hereunder. The provisions of this Section 3.2 are
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement of mutilated, lost, stolen or destroyed
Warrant Certificates.

     3.3 HOLDER OF WARRANT CERTIFICATE MAY ENFORCE RIGHTS. Notwithstanding any
of the provisions of this Agreement, any holder of any Warrant Certificate,
without the consent of the Warrant Agent, the [Senior] [Subordinated] Trustee,
the holder of any Warrant Debt Securities or the holder of any other Warrant
Certificate, may, in such holder's own behalf and for such holder's own benefit,
enforce, and may institute and maintain any suit, action or proceeding against
the Company suitable to enforce, or otherwise in respect of, such holder's right
to exercise the Warrants evidenced by such holder's Warrant Certificate in the
manner provided in such holder's Warrant Certificates and in this Agreement.

     3.4 MERGER, SALE, CONVEYANCE OR LEASE. In case of (a) any share exchange,
merger or similar transaction of the Company with or into another person or
entity (other than a share exchange, merger or similar transaction in which the
Company is the acquiring or surviving corporation) or (b) the sale, exchange,
lease, transfer or other disposition of all or substantially all of the
properties and assets of the Company as an entirety (in any such case, a
"REORGANIZATION EVENT"), then, as a condition of such Reorganization Event,
lawful provisions shall be made, and duly executed documents evidencing the same
from the Company's successor shall be delivered to the holders of the Warrants,
so that such successor shall succeed to and be substituted for the Company, and
assume all the Company's obligations under, this Agreement and the Warrants. The
Company shall thereupon be relieved of any further obligation hereunder or under
the Warrants, and the Company as the predecessor corporation may thereupon or at
any time thereafter be dissolved, wound up or liquidated. Such successor or
assuming entity thereupon may cause to be signed, and may issue either in its
own name or in the name of the Company, any or all of the Warrants issuable
hereunder which heretofore shall not have been signed by the Company, and may
execute and deliver securities in its own name, in fulfillment of its
obligations to deliver Warrant Debt Securities upon exercise of the Warrants.
All the Warrants so issued shall in all respects have the same legal rank and
benefit under this Agreement as the Warrants theretofore or thereafter issued in
accordance with the terms of this Agreement as though all of such Warrants had
been issued at the date of the execution hereof. In any case of any such
Reorganization Event, such changes in phraseology and form (but not in
substance) may be made in the Warrants thereafter to be issued as may be
appropriate.

     The Warrant Agent may receive a written opinion of legal counsel as
conclusive evidence that any such Reorganization Event complies with the
provisions of this Section 3.4.

                                        7

     3.5 NOTICE TO WARRANTHOLDERS. In case the Company shall (a) effect any
Reorganization Event or (b) make any distribution on or in respect of the [title
of Warrant Debt Securities] in connection with the dissolution, liquidation or
winding up of the Company, then the Company shall mail to each holder of
Warrants at such holder's address as it shall appear on the books of the Warrant
Agent, at least ten days prior to the applicable date hereinafter specified, a
notice stating the date on which such Reorganization Event, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of [title of Warrant Debt Securities] of
record shall be entitled to exchange their shares of [title of Warrant Debt
Securities] for securities or other property deliverable upon such
Reorganization Event, dissolution, liquidation or winding up. No failure to mail
such notice nor any defect therein or in the mail in thereof shall affect any
such transaction.

                                    ARTICLE 4
                  EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES

     4.1 EXCHANGE AND TRANSFER OF WARRANT CERTIFICATES. [If Other Securities
with Warrants which are immediately detachable--Upon] [If Other Securities with
Warrants which are not immediately detachable--Prior to the Detachable Date, a
Warrant Certificate may be exchanged or transferred only together with the Other
Security to which the Warrant Certificate was initially attached, and only for
the purpose of effecting or in conjunction with an exchange or transfer of such
Other Security. Prior to any Detachable Date, each transfer of the Other
Security shall operate also to transfer the related Warrant Certificates. After
the Detachable Date, upon] surrender at the corporate trust office of the
Warrant Agent, Warrant Certificates evidencing Warrants may be exchanged for
Warrant Certificates in other denominations evidencing such Warrants or the
transfer thereof may be registered in whole or in part; provided that such other
Warrant Certificates evidence Warrants for the same aggregate principal amount
of Warrant Debt Securities as the Warrant Certificates so surrendered. 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 and exchanges and transfers of outstanding Warrant Certificates,
upon surrender of the Warrant Certificates to the Warrant Agent at its corporate
trust office for exchange or registration of transfer, properly endorsed or
accompanied by appropriate instruments of registration of transfer and written
instructions for transfer, all in form satisfactory to the Company and the
Warrant Agent. No service charge shall be made for any exchange or registration
of transfer 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 exchange or registration of transfer.
Whenever any Warrant Certificates are so surrendered for exchange or
registration of transfer, an authorized officer of the Warrant Agent shall
manually countersign and deliver to the person or persons entitled thereto a
Warrant Certificate or Warrant Certificates duly authorized and executed by the
Company, as so requested. The Warrant Agent shall not be required to effect any
exchange or registration of transfer which will result in the issuance of a
Warrant Certificate evidencing a Warrant for a fraction of a Warrant Debt
Security or a number of Warrants for a whole number of Warrant Debt Securities
and a fraction of a Warrant Debt Security. All Warrant Certificates issued upon
any exchange or registration of transfer of Warrant Certificates shall be the
valid obligations of the Company, evidencing the same obligations and entitled
to the same benefits under this Agreement as the Warrant Certificate surrendered
for such exchange or registration of transfer.

     4.2 TREATMENT OF HOLDERS OF WARRANT CERTIFICATES. [If Other Securities and
Warrants are not immediately detachable--Prior to the Detachable Date, the
Company, the Warrant Agent and all other persons may treat the owner of the
Other Security as the owner of the Warrant Certificates initially attached
thereto for any purpose and as the person entitled to exercise the rights
represented by the Warrants evidenced by such Warrant Certificates, any notice
to the contrary notwithstanding. After the Detachable Date and prior to due
presentment of a Warrant Certificate for registration of transfer, the] [The]
Company, the Warrant Agent and all other persons may treat the registered holder
of a Warrant Certificate as the absolute owner thereof for any purpose and as
the person entitled to exercise the rights represented by the Warrants evidenced
thereby, any notice to the contrary notwithstanding.

     4.3 CANCELLATION OF WARRANT CERTIFICATES. Any Warrant Certificate
surrendered for exchange, registration of transfer or exercise of the Warrants
evidenced thereby shall, if surrendered to the Company, be delivered to the
Warrant Agent and all Warrant Certificates surrendered or so delivered to the
Warrant Agent 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 exchange therefor or 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.

governed by the terms and provisions hereof.

its obligations herein set forth upon the terms and conditions hereof, including
the following to all of which the Company agrees and to all of which the rights
hereunder of the holders from time to time of the Warrant Certificates shall be
subject:

     (a) COMPENSATION AND INDEMNIFICATION. The Company agrees promptly to pay
the Warrant Agent the compensation to be agreed upon with the Company for all
services rendered by the Warrant Agent and to reimburse the Warrant Agent for
reasonable out-of-pocket expenses (including reasonable counsel fees) incurred

connection with the services rendered hereunder by the Warrant Agent. The
Company also agrees to indemnify the Warrant Agent for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, bad faith
or willful misconduct on the part of the Warrant Agent, arising out of or in
connection with its acting as Warrant Agent hereunder, including the reasonable
costs and expenses of defending against any claim of such liability.

     (b) AGENT FOR THE COMPANY. In acting under this Warrant Agreement and in
connection with the Warrant Certificates, the Warrant Agent is acting solely as
agent of the Company and does not assume any obligations or relationship of
agency or trust for or with any of the holders of Warrant Certificates or
beneficial owners of Warrants.

     (c) COUNSEL. The Warrant Agent may consult with counsel satisfactory to it,
which may include counsel for the Company, and the written advice of such
counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in

     (e) CERTAIN TRANSACTIONS. The Warrant Agent, and its officers, directors
and employees, may become the owner of, or acquire any interest in, Warrants,
with the same rights that it or they would have if it were not the Warrant Agent
hereunder, and, to the extent permitted by applicable law, it or they may engage
or be interested in any financial or other transaction with the Company and may
act on, or as depositary, trustee or agent for, any committee or body of holders
of Warrant Securities or other obligations of the Company as freely as if it
were not the Warrant Agent hereunder. Nothing in this Warrant Agreement shall be
deemed to prevent the Warrant Agent from acting as [Senior] [Subordinated]
Trustee under the [Senior] [Subordinated] indenture.

     (f) NO LIABILITY FOR INTEREST. Unless otherwise agreed with the Company,
the Warrant Agent shall have no liability for interest on any monies at any time

accountable or under any duty or responsibility for the use by the Company of
any of the Warrant Certificates authenticated by the Warrant Agent and delivered
by it to the Company pursuant to this Agreement or for the application by the
Company of the proceeds of the Warrant Certificates. The Warrant Agent shall
have no duty or responsibility in case of any default by the Company in the
performance of its covenants or agreements contained herein or in the Warrant
Certificates or in the case of the receipt of any written demand from a holder
of a Warrant Certificate with respect to such default, including, without
limiting the generality of the foregoing, any duty or responsibility to initiate
or attempt to initiate any proceedings at law or otherwise or, except as
provided in Section 6.2 hereof, to make any demand upon the Company.

     (a) The Company agrees, for the benefit of the holders from time to time of
the Warrant Certificates, that there shall at all times be a Warrant Agent
hereunder until all the Warrants have been exercised or are no longer
exercisable.

     (b) The Warrant Agent may at any time resign as agent by giving written
notice to the Company of such intention on its part, specifying the date on
which its desired resignation shall become effective; provided that such date
shall not be less than three months after the date on which such notice is given
unless the Company otherwise agrees. The Warrant Agent hereunder may be removed
at any time by the filing with it of an instrument in writing signed by or on
behalf of the Company and specifying such removal and the intended date when it
shall become effective. Such resignation or removal shall take effect upon the
appointment by the Company, as hereinafter provided, of a successor Warrant
Agent (which shall be a bank or trust company authorized under the laws of the
jurisdiction of its organization to exercise corporate trust powers) and the
acceptance of such appointment by such successor Warrant Agent. The obligation
of the Company under Section 5.2(a) shall continue to the extent set forth
therein notwithstanding the resignation or removal of the Warrant Agent.

removed, or shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or shall commence a voluntary case under the Federal bankruptcy laws,

           FORM OF RECEIPTS, DEPOSIT OF STOCK, EXECUTION AND DELIVERY,
          TRANSFER, SURRENDER AND REDEMPTION AND REPURCHASE OF RECEIPTS

     SECTION 2.1 FORM AND TRANSFER OF RECEIPTS. Receipts shall be engraved or
printed or lithographed unless they are evidenced by a global receipt held by a
depositary for a clearing system and shall be substantially in the form set
forth in Exhibit A annexed to this Deposit Agreement, with appropriate
insertions, modifications and omissions to reflect the terms of any Certificate
of Designation or otherwise, as hereinafter provided. Receipts shall be executed
by the Depositary by the manual signature of a duly authorized officer of the
Depositary; provided, however, that such signature may be a facsimile if a
Registrar (other than the Depositary) shall have countersigned the Receipts by
manual signature of a duly authorized officer of the Registrar. Pending the
preparation of definitive Receipts, the Depositary, upon the written order of
the Company delivered in accordance with Section 2.2, shall execute and deliver
temporary Receipts which shall be printed, lithographed, typewritten, or
otherwise reproduced substantially of the tenor of the definitive Receipts in
lieu of which they are issued and with appropriate insertions, modifications,
omissions, substitutions and other variations as the persons executing such
Receipts may determine are necessary for such temporary Receipts, as evidenced
by their execution of such temporary Receipts. If temporary Receipts are issued,
the Company and the Depositary will cause definitive Receipts to be prepared
without unreasonable delay; provided that if such temporary Receipts are global
Receipts held by a depositary for a clearing system, definitive Receipts need
not be prepared until the Receipts cease to be so held. After the preparation of
definitive Receipts, the temporary Receipts shall be exchangeable for definitive
Receipts upon surrender of the temporary Receipts at the Corporate Office or
such other office as the Depositary may designate, without charge to the holder.
Upon surrender for cancellation of any one or more temporary Receipts, the
Depositary shall execute and deliver in exchange therefore definitive Receipts
representing the same number of Depositary Shares as represented by the
surrendered temporary Receipt or Receipts. Such exchange shall be made at the
Company's expense and without any charge therefore. Until so exchanged, the
temporary Receipts shall in all respects be entitled to the same benefits under
this Deposit Agreement, and with respect to the Stock, as definitive Receipts.

     No Receipt shall be entitled to any benefits under this Deposit Agreement
or be valid or obligatory for any purpose unless it shall have been executed
as provided in the preceding paragraph.

                                        2

<PAGE>

     The Depositary shall record on its books each Receipt executed as provided
above and delivered as hereinafter provided. Receipts bearing the facsimile
signature of anyone who was at any time a duly authorized officer of the
Depositary shall bind the Depositary, notwithstanding that such officer has
ceased to hold such office prior to the delivery of such Receipts.

     Receipts may be issued in denominations of any number of whole Depositary
Shares. All Receipts shall be dated the date of their execution.

     Receipts may be endorsed with or have incorporated in the text thereof such
legends or recitals or changes not inconsistent with the provisions of this
Deposit Agreement as may be required by the Depositary or required to comply
with any applicable law or regulation or with the rules and regulations of any
securities exchange upon which the Stock or the Depositary Shares may be listed
or to conform with any usage with respect thereto, or to indicate any special
limitations or restrictions to which any particular Receipts are subject by
reason of the date of issuance of the Stock or otherwise.

     Title to any Receipt (and to the Depositary Shares evidenced by such
Receipt) that is properly endorsed or accompanied by a properly executed
instrument of transfer shall be transferable by delivery with the same effect as
in the case of investment securities in general; provided, however, that the
Depositary may, notwithstanding any notice to the contrary, treat the record
holder thereof at such time as the absolute owner thereof for the purpose of
determining the person entitled to distributions of dividends or other
distributions or to any notice provided for in this Deposit Agreement and for
all other purposes.

     SECTION 2.2 DEPOSIT OF STOCK; EXECUTION AND DELIVERY OF RECEIPTS IN RESPECT
THEREOF. Subject to the terms and conditions of this Deposit Agreement, the
Company or any holder of Stock may deposit such Stock under this Deposit
Agreement by delivery to the Depositary of a certificate or certificates for the
Stock to be deposited, properly endorsed or accompanied, if required by the
Depositary, by a properly executed instrument of transfer in form satisfactory
to the Depositary, together with (i) all such certifications as may be required
by the Depositary in accordance with the provisions of this Deposit Agreement
and (ii) a written order of the Company or such holder, as the case may be,
directing the Depositary to execute and deliver to or upon the written order of
the person or persons stated in such order a Receipt or Receipts for the number
of Depositary Shares representing such deposited Stock.

     Upon receipt by the Depositary of a certificate or certificates for Stock
to be deposited hereunder, together with the other documents specified above,
the Depositary shall, as soon as transfer and registration can be accomplished,
present such certificate or certificates to the registrar and transfer agent of
the Stock for transfer and registration in the name of the Depositary or its
nominee of the Stock being deposited. Deposited Stock shall be held by the
Depositary in an account to be established by the Depositary at the Corporate
Office.

     Upon receipt by the Depositary of a certificate or certificates for Stock
to be deposited hereunder, together with the other documents specified above,
the Depositary, subject to the terms and conditions of this Deposit Agreement,
shall execute and deliver, to or upon the order of the person or persons named
in the written order delivered to the Depositary referred to in the first
paragraph of this Section 2.2, a Receipt or Receipts for the number of whole
Depositary Shares representing the Stock so deposited and registered in such
name or names as may be requested by such person or persons. The Depositary
shall execute and deliver such Receipt or Receipts at the Corporate Office,
except that, at the request, risk and expense of any person requesting such
delivery and for such person's account or, upon the order of such person, any
other person's account, such delivery may be made at such other place as may be
designated by such person. In each case, delivery will be made only upon payment
to the Depositary of all taxes and other governmental charges and any fees
payable in connection with such deposit and the transfer of the deposited Stock.

     The Company shall deliver to the Depositary from time to time such
quantities of Receipts as the Depositary may request to enable the Depositary to
perform its obligations under this Deposit Agreement.

     SECTION 2.3 REDEMPTION AND REPURCHASE OF STOCK. Whenever the Company shall
redeem shares of Stock in accordance with a Certificate of Designation, it shall
(unless otherwise agreed in writing with the Depositary) give the Depositary in
its capacity as Depositary not less than 3 business days' prior notice of the
proposed date of the mailing of a notice of redemption of Stock and the
simultaneous redemption of the Depositary Shares representing the Stock to be
redeemed and of the number of such shares of Stock held by the Depositary to be
redeemed. Unless the Certificate of Designation for a specific series of Stock
provides for a different notice period with respect to that Stock in the event
of its redemption, the Depositary shall, as directed by the Company in writing,
mail, first class postage prepaid, notice of the redemption of Stock and the
proposed simultaneous redemption of the Depositary Shares representing the Stock
to be redeemed not less than 30 and not more than 60 days prior to the date
fixed for redemption of such Stock and Depositary Shares, to the record holders
of the Receipts evidencing the Depositary Shares to be so redeemed at the
addresses of such holders as the same appear on the records of the Depositary or
any Depositary's Agent or Registrar. Notwithstanding the foregoing, neither
failure to mail or publish any such notice to one or more such holders nor any
defect in any notice shall affect the sufficiency of the proceedings for
redemption. The Company shall provide the Depositary with such notice, and each
such notice shall state the method for determining the amount payable per
Depositary Share, the redemption date, and the number of Depositary Shares to be
redeemed, and such notice shall call upon each holder of Depositary Shares to
surrender, on the redemption date and at the place or places designated by the
Company, the Receipts evidencing Depositary Shares to be redeemed. On the date
of any such redemption the Depositary shall surrender the certificate or
certificates held by the Depositary evidencing the number of shares of Stock to
be redeemed in the manner specified in the notice of redemption of Stock
provided by the Company pursuant to the applicable Certificate of Designation.
The Depositary shall, thereafter, redeem the number of Depositary Shares
representing such redeemed Stock upon the surrender of Receipts evidencing such
Depositary Shares in the manner provided in the notice sent to record holders of
Receipts.

     Notice having been mailed by the Depositary as aforesaid, from and after
the redemption date (unless the Company shall have failed to redeem the shares
of Stock to be redeemed by it upon the surrender of the certificate or
certificates therefore by the Depositary as described in the preceding
paragraph), the Depositary Shares called for redemption shall be deemed no
longer to be outstanding and all rights of the holders of Receipts evidencing
such Depositary Shares (except the right to receive the cash, securities or
other property payable upon redemption upon surrender of such Receipts) shall,
to the extent of such Depositary Shares, cease and terminate. The foregoing
shall be subject further to the terms and conditions of the applicable
Certificate of Designation.

     If fewer than all the Depositary Shares are to be redeemed, the Depositary
Shares to be redeemed will be selected by lot or proportionately, as may be
determined by the Depositary. If fewer than all of the Depositary Shares
evidenced by a Receipt are called for redemption, the Depositary will deliver to
the holder of such Receipt upon its surrender to the Depositary, cash,
securities or other property payable upon redemption in respect of the
Depositary Shares called for redemption and a new Receipt evidencing the
Depositary Shares evidenced by such prior Receipt and not called for redemption.

     The Depositary shall not be required to transfer or exchange for another
Receipt any Receipt evidencing Depositary Shares called or being called for
redemption, in whole or in part except as provided in the immediately preceding
paragraph of this Section 2.3.

     Whenever the Company shall be required to make an offer to repurchase
Depositary Shares representing Stock in accordance with a Certificate of
Designation, it shall (unless otherwise agreed in writing with the Depositary)
give the Depositary in its capacity as Depositary not less than 3 business days'
prior notice of the required date of the mailing of a notice of the repurchase
offer. The Depositary shall, as directed by the Company in writing, mail, first
class postage prepaid, notice of the relevant terms of the repurchase offer, as
provided by the Company, to the record holders of the Receipts at the addresses
of such holders as the same appear on the records of the Depositary or any
Depositary's Agent or Registrar, including: (i) that such notice is being given
pursuant to a repurchase offer, (ii) the number of Depositary Shares and Stock
for which the offer is being made, (iii) the method for determining the amount
payable per Depositary Share, (iv) the last date, which, unless the Certificate
of Designation for a specific series of Stock provides for a different period
with respect to that Stock in the event that the Company is required to make an
offer to repurchase it, shall not be less than 30 nor more than 60 days after
the date of such notice, by which a holder must elect to accept the repurchase
offer, (v) the procedures that such holder must follow to exercise its rights,
and (vi) the procedures for withdrawing an election.

                                        4

<PAGE>

     The Depositary shall, thereafter, receive from each holder electing to have
Depositary Shares repurchased pursuant to the repurchase offer in accordance
with the instructions in the notice, the holder's Receipts, with an appropriate
form duly completed prior to the repurchase date. Holders will be entitled to
withdraw an election by a written notice of withdrawal delivered to the
Depositary prior to the close of business on the repurchase date. The notice of
withdrawal shall state the number of Depositary Shares and the Receipt numbers
to which the notice of withdrawal relates and the number of Depositary Shares
and Receipt numbers, if any, which remain subject to election. In case the
aggregate number of Depositary Shares offered for repurchase by the holders
exceeds the amount of Depositary Shares which the Company has offered to
repurchase pursuant to the repurchase offer, the Depositary Shares to be
repurchased shall be selected by the Depositary by lot or proportionately, as
may be determined by the Depositary. The Depositary shall, at the direction of
the Company, cause payment to be mailed or delivered to each tendering holder as
promptly as reasonably practicable after the repurchase date, in the amount of
the repurchase price for the Depositary Shares tendered, and any unpurchased
Depositary Shares to be returned to the holder thereof. The foregoing is subject
further to the terms and conditions of the applicable Certificate of
Designation.

     SECTION 2.4 REGISTER OF TRANSFER OF RECEIPTS. Subject to the terms and
conditions of this Deposit Agreement, the Depositary shall register on its books
from time to time transfers of Receipts upon any surrender thereof at the
Corporate Office, or such other office as the Depositary may designate for such
purpose, by the record holder in person or by a duly authorized attorney,
properly endorsed or accompanied by a properly executed instrument of transfer,
together with evidence of the payment of any transfer taxes as may be required
by law. Upon such surrender, the Depositary shall execute a new Receipt or
Receipts and deliver the same to or upon the order of the person entitled
thereto evidencing the same aggregate number of Depositary Shares evidenced by
the Receipt or Receipts surrendered.

     SECTION 2.5 COMBINATION AND SPLIT-UPS OF RECEIPTS. Upon surrender of a
Receipt or Receipts at the Corporate Office, or such other office as the
Depositary may designate for the purpose of effecting a split-up or combination
of Receipts, subject to the terms and conditions of this Deposit Agreement, the
Depositary shall execute and deliver a new Receipt or Receipts in the authorized
denominations requested evidencing the same aggregate number of Depositary
Shares evidenced by the Receipt or Receipts surrendered; provided, however, that
the Depositary shall not issue any Receipt evidencing a fractional Depositary
Share.

     SECTION 2.6 SURRENDER OF RECEIPTS AND WITHDRAWAL OF STOCK. Any holder of a
Receipt, including the Company, shall have the right, upon payment of any amount
due to the Depositary with respect to the Receipt, to withdraw any or all of the
Stock (but only in whole shares of Stock) represented by the Depositary Shares
and all money and other property, if any, represented by such Depositary Shares
by surrendering the Receipt or Receipts evidencing such Depositary Shares at the
Corporate Office, or at such other office as the Depositary may designate for
such withdrawals (and cancellation of the surrendered Receipts as provided in
Section 2.9). After such surrender, without unreasonable delay, the Depositary
shall deliver to the holder the whole number of shares of Stock and all such
money and other property, if any, represented by the Depositary Shares evidenced
by the Receipt or Receipts so surrendered for withdrawal. If the Receipt or
Receipts delivered by the holder to the Depositary in connection with such
withdrawal shall evidence a number of Depositary Shares in excess of the number
of whole Depositary Shares representing the whole number of shares of Stock to
be withdrawn, the Depositary shall at the same time, in addition to such whole
number of shares of Stock and such money and other property, if any, to be
withdrawn, deliver to the holder, or (subject to Section 2.4) upon its order, a
new Receipt or Receipts evidencing such excess number of whole Depositary
Shares.

     Delivery of the Stock and such money and other property being withdrawn may
be made by the delivery of such certificates, documents of title and other
instruments as the Depositary may deem appropriate, which, if required by the
Depositary, shall be properly endorsed or accompanied by proper instruments of
transfer.

     The Depositary shall deliver the Stock and the money and other property, if
any, represented by the Depositary Shares evidenced by Receipts surrendered for
withdrawal, without unreasonable delay, at the office at which such Receipts
were surrendered, except that, at the request, risk and expense of the Company
such delivery may be made, without unreasonable delay, at such other place as
may be designated by the Company.

                                        5

<PAGE>

     For purposes of determining the number of Depositary Shares outstanding on
any dividend payment date, the Receipts representing Depositary Shares acquired
by the Company on or prior to such dividend payment date and not theretofore
delivered to the Depositary for withdrawal and cancellation shall be deemed to
be outstanding.

     SECTION 2.7 LIMITATIONS ON EXECUTION AND DELIVERY, TRANSFER, SPLIT-UP,
COMBINATION AND SURRENDER OF RECEIPTS AND WITHDRAWAL OR DEPOSIT OF STOCK. As a
condition precedent to the execution and delivery, registration of transfer,
split-up, combination, or surrender of any Receipt, the delivery of any
distribution thereon or withdrawal or deposit of Stock, or the exercise of any
conversion right referred to in Section 2.10, the Depositary, any of the
Depositary's Agents, the Registrar or the Company may require any or all of the
following: (i) payment to it of a sum sufficient for the payment (or, in the
event that the Depositary or the Company shall have made such payment, the
reimbursement to it) of any tax or other governmental charge or fee with respect
thereto (including any such tax or charge or fee with respect to the Stock being
deposited or the Stock being withdrawn or with respect to property of the
Company being issued upon redemption or conversion); (ii) production of proof
satisfactory to it as to the identity and genuineness of any signature; and
(iii) compliance with such reasonable regulations, if any, as the Depositary or
the Company may establish not inconsistent with the provisions of this Deposit
Agreement.

     The deposit of Stock may be refused, or the registration of transfer,
split-up, combination or surrender of outstanding Receipts and the withdrawal of
deposited Stock or the exercise of any conversion right referred to in Section
2.10 may be suspended (i) during any period when the register of stockholders of
the Company is closed, (ii) if any such action is deemed necessary or advisable
by the Depositary, any of the Depositary's Agents or the Company at any time or
from time to time because of any requirement of law or of any government or
governmental body or commission, or under any provision of this Deposit
Agreement, or (iii) with the approval of the Company, for any other reason.
Without limitation of the foregoing, the Depositary shall not knowingly accept
for deposit under this Deposit Agreement any shares of Stock that are required
to be registered under the Securities Act unless a registration statement under
the Securities Act is in effect as to such shares of Stock.

     SECTION 2.8 LOST RECEIPTS, ETC. In case any Receipt shall be mutilated or
destroyed or lost or stolen, the Depositary shall execute and deliver a Receipt
of like form and tenor in exchange and substitution for such mutilated Receipt
or in lieu of and in substitution for such destroyed, lost or stolen Receipt
unless the Depositary has notice that such Receipt has been acquired by a bona
fide purchaser; provided, however, that the holder thereof provides the
Depositary with (i) evidence satisfactory to the Depositary of such destruction,
loss or theft of such Receipt, of the authenticity thereof and of his ownership
thereof, (ii) reasonable indemnification satisfactory to the Depositary or the
payment of any charges incurred by the Depositary in obtaining insurance in lieu
of such indemnification and (iii) payment of any expense (including fees,
charges and expenses of the Depositary) in connection with such execution and
delivery.

     SECTION 2.9 CANCELLATION AND DESTRUCTION OF SURRENDERED RECEIPTS. All
Receipts surrendered to the Depositary or any Depositary's Agent shall be
cancelled by the Depositary. Except as prohibited by applicable law or
regulation, the Depositary is authorized to destroy such Receipts so canceled.

     SECTION 2.10 CONVERSION. In the event that the Stock, in accordance with
its Certificate of Designation, is convertible into the Company's common stock
or other securities, subject to the terms and conditions of this Deposit
Agreement, a holder of a Receipt or Receipts may surrender such Receipt or
Receipts at the Corporate Office or at such other office or to a Depositary's
Agent that the Depositary may designate for such purpose, together with a notice
of conversion duly completed and executed, thereby directing the Depositary or
such Depositary's Agent to instruct the Company to cause the conversion of the
number of shares of Stock specified in such notice of conversion into shares of
the Company's common stock or other securities at the rate specified in the
applicable Certificate of Designation, and an assignment of such Receipt or
Receipts to the Company or in blank, duly completed and executed, along with any
other documents or instruments and any amounts required by the applicable
Certificate of Designation.

     Upon receipt by the Depositary or a Depositary's Agent of a Receipt or
Receipts, together with a notice of conversion, duly completed and executed,
directing the Depositary or such Depositary's Agent to instruct the Company to
cause the conversion of a specified number of shares of Stock at the rate
specified in the applicable Certificate of Designation, and an assignment of
such Receipt or Receipts to the Company or in blank, duly

                                        6

<PAGE>

completed and executed, along with any other documents or instruments or amounts
referred to in the preceding paragraph, the Depositary or such Depositary's
Agent shall instruct the Company, subject to any adjustment provided for in the
applicable Certificate of Designation, (i) to cause the conversion at the rate
specified in the applicable Certificate of Designation of the number of shares
of Stock represented by the Depositary Shares evidenced by the Receipt or
Receipts so surrendered for conversion as specified in the written notice to the
Depositary or such Depositary's Agent and (ii) to cause the delivery to the
holder of such Receipt or Receipts of (a) a certificate or certificates
evidencing the number of whole shares of the Company's common stock or other
securities into which such Stock has been converted, and (b) the amount of cash
or other property, if any, to which such holder is entitled in lieu of
fractional shares of, or fractional interests in, the Company's common stock or
other securities otherwise deliverable by the Company upon such conversion,
calculated in accordance with the applicable Certificate of Designation. The
Company shall as promptly as practicable after receipt thereof cause the
delivery of the certificate or certificates and cash or other property, if any,
referred to in clauses (a) and (b) above, and such conversion shall be deemed to
have been effected immediately prior to the close of business on the date of
such receipt and shall occur at the rate specified in the Certificate of
Designation in effect at such time and on such date. Upon such conversion, the
Depositary or such Depositary's Agent (i) shall deliver to the holder a Receipt
evidencing the number of Depositary Shares evidenced by the surrendered Receipt
or Receipts in excess of the number of Depositary Shares evidenced by such
Receipt or Receipts that have been so converted, (ii) shall cancel the Receipts
surrendered for conversion and (iii) shall deliver to the Company for
cancellation the number of shares of Stock evidenced by the Receipts so
surrendered and so converted. Upon the delivery of the shares of Stock to be
cancelled due to such conversion by the Depositary or such Depositary's Agent to
the Company, the Company shall deliver to the Depositary or such Depositary's
Agent, as applicable, a certificate or certificates evidencing the number of
shares of Stock, if any, that equals the excess of the number of shares
evidenced by the surrendered certificate over the number of shares evidenced by
that certificate that have been so converted. Depositary Shares converted in
connection with conversion of the Stock represented thereby shall only be
converted in whole, and not in part.

     Upon the conversion of any Stock for which a notice of conversion has been
provided to the Depositary or a Depositary's Agent by the holder of the Receipt
or Receipts representing such Stock, the Depositary Shares evidenced by such
Receipt or Receipts shall be deemed no longer outstanding, all rights of the
holder of the Receipt or Receipts evidencing such Depositary Shares (except the
right to receive (i) the Company's common stock or other securities to which
such holder is entitled upon conversion in accordance with the applicable
Certificate of Designation, (ii) any cash or other property payable in
accordance with the applicable Certificate of Designation with respect to any
fractional shares or other fractional interests in the Company's common stock or
other securities otherwise deliverable by the Company upon conversion, (iii) any
Receipts evidencing Depositary Shares representing Stock which was not so
converted and (iv) any other securities, property or cash to which such holder
is entitled under this Deposit Agreement) shall cease and terminate, and the
Receipt or Receipts evidencing such Depositary Shares shall be cancelled. No
fractional shares or other fractional interests in the Company's common stock or
other securities shall be deliverable by the Company upon conversion of the
Stock represented by the Depositary Shares.

                                   ARTICLE III
           CERTAIN OBLIGATIONS OF HOLDERS OF RECEIPTS AND THE COMPANY

     SECTION 3.1 FILING PROOFS, CERTIFICATES AND OTHER INFORMATION. Any person
presenting Stock for deposit or any holder of a Receipt may be required from
time to time to file such proof of residence or other information, to execute
such certificates and to make such representations and warranties as the
Depositary or the Company may reasonably deem necessary or proper. The
Depositary or the Company may withhold or delay the delivery of any Receipt, the
registration of transfer or redemption of any Receipt, the withdrawal of the
Stock represented by the Depositary Shares evidenced by any Receipt, the
distribution of any dividend or other distribution or the exercise of any
conversion right referred to in Section 2.10, or refuse to accept Receipts that
are delivered for surrender, until such proof or other information is filed,
such certificates are executed or such representations and warranties are made.

     SECTION 3.2 PAYMENT OF TAXES OR OTHER GOVERNMENTAL CHARGES. If any tax or
other governmental charge or fee shall become payable by or on behalf of the
Depositary with respect to (i) any Receipt, (ii) the Depositary Shares evidenced
by such Receipt, (iii) the Stock (or fractional interest therein) or other
property represented by such Depositary Shares, or (iv) any transaction referred
to in Section 4.6, such tax (including transfer,

                                        7

<PAGE>

issuance or acquisition taxes, if any) or governmental charge or fee shall be
payable by the holder of such Receipt, who shall pay the amount thereof to the
Depositary. Until such payment is made, registration or transfer of any Receipt
or any split-up or combination thereof or any withdrawal of the Stock or money
or other property, if any, represented by the Depositary Shares evidenced by
such Receipt or Receipts delivered for surrender or the exercise of any
conversion right referred to in Section 2.10 may be refused, any dividend or
other distribution may be withheld and any part or all of the Stock or other
property represented by the Depositary Shares evidenced by such Receipt may be
sold for the account of the holder thereof (after attempting by reasonable means
to notify such holder prior to such sale). Any dividend or other distribution so
withheld and the proceeds of any such sale may be applied to any payment of such
tax or other governmental charge or fee, the holder of such Receipt remaining
liable for any deficiency.

     SECTION 3.3 WITHHOLDING. The Depositary shall act as the tax withholding
agent for any payments, distributions made with respect to the Depositary Shares
and Receipts, and the Stock. The Depositary shall be responsible with respect to
the Depositary Shares, Receipts and Stock for the timely (i) collection and
deposit of any required withholding or backup withholding tax, and (ii) filing
of any information returns or other documents with federal (and other
applicable) taxing authorities.

     SECTION 3.4 REPRESENTATIONS AND WARRANTIES AS TO STOCK. In the case of the
initial deposit of the Stock, the Company and, in the case of subsequent
deposits thereof, each person so depositing Stock under this Deposit Agreement
shall be deemed thereby to represent and warrant that such Stock and each
certificate therefore are valid and that the person making such deposit is duly
authorized to do so. Such representations and warranties shall survive the
deposit of the Stock and the issuance of Receipts therefor.

                                   ARTICLE IV
                               THE STOCK, NOTICES

     SECTION 4.1 CASH DISTRIBUTIONS. Whenever the Depositary shall receive any
cash dividend or other cash distribution on the Stock (other than cash dividends
or cash distributions paid by the Company in lieu of fractional shares or other
fractional interests in the Company's common stock or other securities otherwise
deliverable by the Company in accordance with the applicable Certificate of
Designation), the Depositary shall, subject to Section 3.2, distribute to record
holders of Receipts on the record date fixed pursuant to Section 4.4 such
amounts of such sum as are, as nearly as practicable, in proportion to the
respective numbers of Depositary Shares evidenced by the Receipts held by such
holders; provided, however, that in case the Company or the Depositary shall be
required by law to withhold and does withhold from any cash dividend or other
cash distribution in respect of the Stock an amount on account of taxes, the
amount made available for distribution or distributed in respect of Depositary
Shares shall be reduced accordingly. The Depositary shall distribute or make
available for distribution, as the case may be, only such amount, however, as
can be distributed without attributing to any holder of Depositary Shares a
fraction of one cent and any balance not so distributable shall be held by the
Depositary (without liability for interest thereon) and shall be added to and be
treated as part of the next sum received by the Depositary for distribution to
record holders of Receipts then outstanding.

     SECTION 4.2 DISTRIBUTIONS OTHER THAN CASH. Whenever the Depositary shall
receive any distribution other than cash, rights, preferences or privileges upon
the Stock, the Depositary shall, subject to Section 3.2, distribute to record
holders of Receipts on the record date fixed pursuant to Section 4.4 such
amounts of the securities or property received by it as are, as nearly as
practicable, in proportion to the respective numbers of Depositary Shares
evidenced by the Receipts held by such holders, in any manner that the
Depositary and the Company may deem equitable and practicable for
accomplishing such distribution. If, in the opinion of the Company after
consultation with the Depositary, such distribution cannot be made
proportionately among such record holders, or if for any other reason (including
any tax withholding or securities law requirement), the Depositary deems, after
consultation with the Company, such distribution not to be feasible, the
Depositary may, with the approval of the Company which approval shall not be
unreasonably withheld, adopt such method as it deems equitable and practicable
for the purpose of effecting such distribution, including the sale (at public or
private sale) of the securities or property thus received, or any part thereof,
at such place or places and upon such terms as it may deem proper. The net
proceeds of any such sale shall, subject to Section 3.2, be distributed or
made available for distribution, as the case may be, by the Depositary to record
holders of Receipts as provided by Section 4.1 in the case of a distribution
received in cash.

                                        8

<PAGE>

     SECTION 4.3 SUBSCRIPTION RIGHTS, PREFERENCES OR PRIVILEGES. If the Company
shall at any time offer or cause to be offered to the persons in whose names
Stock is registered on the books of the Company any rights, preferences or
privileges to subscribe for or to purchase any securities or any rights,
preferences or privileges of any other nature, such rights, preferences or
privileges shall in each such instance be made available by the Depositary to
the record holders of Receipts in such manner as the Company shall instruct
(including by the issue to such record holders of warrants representing such
rights, preferences or privileges); provided, however, that (i) if at the time
of issue or offer of any such rights, preferences or privileges the Company
determines and instructs the Depositary that it is not lawful or feasible to
make such rights, preferences or privileges available to some or all holders of
Receipts (by the issue of warrants or otherwise) or (ii) if and to the extent
instructed by holders of Receipts who do not desire to exercise such rights,
preferences or privileges, the Depositary shall then, in each case, and if
applicable laws or the terms of such rights, preferences or privileges so
permit, sell such rights, preferences or privileges of such holders at public or
private sale, at such place or places and upon such terms as it may deem proper.
The net proceeds of any such sale shall be distributed by the Depositary to the
record holders of Receipts entitled thereto as provided by Section 4.1 in the
case of a distribution received in cash.

     If registration under the Securities Act of the securities to which any
rights, preferences or privileges relate is required in order for holders of
Receipts to be offered or sold such securities, the Company shall promptly file
a registration statement pursuant to the Securities Act with respect to such
rights, preferences or privileges and securities and use its reasonable best
efforts and take all steps reasonably available to it to cause such registration
statement to become effective sufficiently in advance of the expiration of such
rights, preferences or privileges to enable such holders to exercise such
rights, preferences or privileges. In no event shall the Depositary make
available to the holders of Receipts any right, preference or privilege to
subscribe for or to purchase any securities unless and until such registration
statement shall have become effective or unless the offering and sale of such
securities to such holders are exempt from registration under the provisions of
the Securities Act.

     If any other action under the law of any jurisdiction or any governmental
or administrative authorization, consent or permit is required in order for such
rights, preferences or privileges to be made available to holders of Receipts,
the Company agrees with the Depositary that the Company will use its reasonable
best efforts to take such action or obtain such authorization, consent or permit
sufficiently in advance of the expiration of such rights, preferences or
privileges to enable such holders to exercise such rights, preferences or
privileges.

     SECTION 4.4 NOTICE OF DIVIDENDS, FIXING OF RECORD DATE FOR HOLDERS OF
RECEIPTS. Whenever (i) any cash dividend or other cash distribution shall become
payable, or any distribution other than cash shall be made, or any rights,
preferences or privileges shall at any time be offered, with respect to the
Stock, or (ii) the Depositary shall receive notice of any meeting at which
holders of Stock are entitled to vote or of which holders of Stock are entitled
to notice, or (iii) of any mandatory conversion of, or any election on the part
of the Company to call for the redemption or exchange of, any shares of Stock,
in accordance with the provisions of the applicable Certificate of Designation
or otherwise, the Depositary shall in each such instance fix a record date
(which shall be the same date as the record date fixed by the Company with
respect to the Stock) for the determination of the holders of Receipts (x) who
shall be entitled to receive such dividend, distribution, rights, preferences or
privileges or the net proceeds of the sale thereof, or (y) who shall be entitled
to give instructions for the exercise of voting rights at any such meeting or to
receive notice of such meeting or of such conversion, exchange or redemption.

     SECTION 4.5 VOTING RIGHTS. Upon receipt of notice of any meeting at which
the holders of Stock are entitled to vote, the Depositary shall, as soon as
practicable thereafter, mail to the record holders of Receipts a notice, which
shall be provided by the Company and which shall contain (i) such information as
is contained in such notice of meeting, (ii) a statement that the holders of
Receipts at the close of business on a specified record date fixed pursuant to
Section 4.4 will be entitled, subject to any applicable provision of law, the
Certificate of Incorporation or the applicable Certificate of Designation, to
instruct the Depositary as to the exercise of the voting rights pertaining to
the Stock represented by their respective Depositary Shares and (iii) a brief
statement as to the manner in which such instructions may be given. Upon the
written request of a holder of a Receipt on such record date, the Depositary
shall endeavor insofar as practicable to vote or cause to be voted the Stock
represented by the Depositary Shares evidenced by such Receipt in accordance
with the instructions set forth in such request. The

                                        9

<PAGE>

Company hereby agrees to take all reasonable action that may be deemed necessary
by the Depositary in order to enable the Depositary to vote such Stock or cause
such Stock to be voted. In the absence of specific instructions from the holder
of a Receipt, the Depositary will abstain from voting to the extent of the Stock
represented by the Depositary Shares evidenced by such Receipt.

     SECTION 4.6 CHANGES AFFECTING STOCK AND RECLASSIFICATIONS,
RECAPITALIZATIONS, ETC. Upon any split-up, consolidation or any other
reclassification of Stock, or upon any recapitalization, reorganization, merger,
amalgamation or consolidation affecting the Company or to which it is a party or
sale of all or substantially all of the Company's assets, the Depositary shall
treat any shares of Stock or other securities or property (including cash) that
shall be received by the Depositary in exchange for or in conversion of or in
respect of the Stock as new deposited property under this Deposit Agreement, and
Receipts then outstanding shall thenceforth represent the proportionate
interests of holders thereof in the new deposited property so received in
exchange for or in respect of such Stock. In any such case the Depositary may,
in its discretion, with the approval of the Company, execute and deliver
additional Receipts, or may call for the surrender of all outstanding Receipts
to be exchanged for new Receipts specifically describing such new deposited
property.

     SECTION 4.7 REPORTS. The Company or, at the option of the Company, the
Depositary shall forward to the holders of Receipts any reports and
communications received from the Company that are received by the Depositary as
the holder of Stock.

     SECTION 4.8 LISTS OF RECEIPT HOLDERS. Promptly upon request from time to
time by the Company, the Depositary shall furnish to it a list, as of a recent
date, of the names, addresses and holdings of Depositary Shares of all persons
in whose names Receipts are registered on the books of the Depositary, any
Depositary's Agent or the Registrar. At the expense of the Company, the Company
shall have the right to inspect transfer and registration records of the
Depositary, any Depositary's Agent or the Registrar, take copies thereof and
require the Depositary, any Depositary's Agent or the Registrar to supply copies
of such portions of such records as the Company may request.

                                    ARTICLE V
     THE DEPOSITARY, THE DEPOSITARY'S AGENTS, THE REGISTRAR AND THE COMPANY

     SECTION 5.1 MAINTENANCE OF OFFICES, AGENCIES, TRANSFER BOOKS BY THE
DEPOSITARY; THE REGISTRAR. Upon execution of this Deposit Agreement in
accordance with its terms, the Depositary shall maintain (i) at the Corporate
Office facilities for the execution and delivery, registration, registration of
transfer, surrender, split-up, combination, redemption and conversion of
Receipts and deposit and withdrawal of Stock, and (ii) at the offices of the
Depositary's Agents, if any, facilities for the delivery, registration,
registration of transfer, surrender, split-up, combination, redemption and
conversion of Receipts and deposit and withdrawal of Stock, all in accordance
with the provisions of this Deposit Agreement.

     The Depositary, acting as transfer agent and Registrar, shall keep books at
the Corporate Office for the registration and transfer of Receipts, which books
at all reasonable times shall be open for inspection by the record holders of
Receipts; provided that any such holder requesting to exercise such right shall
certify to the Depositary that such inspection shall be for a proper purpose
reasonably related to such person's interest as an owner of Depositary Shares.
The Depositary shall consult with the Company upon receipt of any request for
inspection. The Depositary may close such books, at any time or from time to
time, when deemed expedient by it in connection with the performance of its
duties hereunder.

     If the Receipts or the Depositary Shares evidenced thereby or the Stock
represented by such Depositary Shares shall be listed on one or more securities
exchanges, the Depositary shall, with the approval of the Company, appoint a
Registrar for registry of such Receipts or Depositary Shares in accordance with
the requirements of such exchange or exchanges. Such Registrar (which may be the
Depositary if so permitted by the requirements of such exchange or exchanges)
may be removed and a substitute Registrar appointed by the Depositary upon the
request or with the approval of the Company. In addition, if the Receipts, such
Depositary Shares or such Stock are listed on one or more securities exchanges,
the Depositary will, at the request of the Company, arrange such facilities for
the delivery, registration, registration of transfer, surrender, split-up,
combination, redemption and conversion of such Receipts, such Depositary Shares
or such Stock as may be required by law or applicable security exchange
regulations.

                                       10

<PAGE>

     SECTION 5.2 PREVENTION OR DELAY IN PERFORMANCE BY THE DEPOSITARY, THE
DEPOSITARY'S AGENTS, THE REGISTRAR OR THE COMPANY. Neither the Depositary nor
any Depositary's Agent nor the Registrar nor the Company shall incur any
liability to any holder of any Receipt, if by reason of any provision of any
present or future law or regulation thereunder of the United States of America
or of any other governmental authority or of any provision, present or future,
of the Certificate of Incorporation or the applicable Certificate of Designation
or by reason of any act of god or war or other circumstances beyond the control
of the relevant party, the Depositary, any Depositary's Agent, the Registrar or
the Company shall be  prevented or forbidden from doing or performing any act
or thing that the terms of this Deposit Agreement provide shall be done or
performed; nor shall the Depositary, any Depositary's Agent, the Registrar or
the Company incur any liability to any holder of a Receipt (i) by reason of any
nonperformance or delay, caused as aforesaid, in the performance of any act or
thing that the terms of this Deposit Agreement provide shall or may be done or
performed, or (ii) by reason of any exercise of, or failure to exercise, any
discretion provided for in this Deposit Agreement except, in the case of the
Depositary, any Depositary's Agent or the Registrar, if any such exercise or
failure to exercise discretion is caused by its negligence or willful
misconduct.

     SECTION 5.3 OBLIGATIONS OF THE DEPOSITARY, THE DEPOSITARY'S AGENTS, THE
REGISTRAR AND THE COMPANY. The Company assumes no obligation and shall be
subject to no liability under this Deposit Agreement or the Receipts to holders
or other persons, except to perform its obligations as are specifically set
forth and undertaken by it to perform in this Deposit Agreement without
negligence or bad faith. Each of the Depositary, the Depositary's Agents and the
Registrar assumes no obligation and shall be subject to no liability under this
Deposit Agreement or the Receipts to holders or other persons, except to perform
such obligations as are specifically set forth and undertaken by it to perform
in this Deposit Agreement without negligence or willful misconduct.

     Neither the Depositary nor any Depositary's Agent nor the Registrar nor the
Company shall be liable for any action or any failure to act by it in reliance
upon the advice of or information from legal counsel, accountants, any person
presenting Stock for deposit, any holder of a Receipt or any other person
believed by it in good faith to be competent to give such advice or information.
The Depositary, any Depositary's Agent, the Registrar and the Company may each
rely and shall each be protected in acting upon any written notice, request,
direction or other document believed by it to be genuine and to have been signed
or presented by the proper party or parties.

     The Depositary, the Registrar and any Depositary's Agent may own and deal
in any class of securities of the Company and its affiliates and in Receipts or
Depositary Shares. The Depositary may also act as transfer agent or Registrar of
any of the securities of the Company and its affiliates.

     It is intended that neither the Depositary nor any Depositary's Agent nor
the Registrar shall be deemed to be an "issuer" of the Stock, the Depositary
Shares, or the Receipts or other securities issued upon conversion, exchange or
redemption of the Stock under the federal securities laws or applicable state
securities laws, it being expressly understood and agreed that the Depositary
and any Depositary's Agent and the Registrar are acting only in a ministerial
capacity; provided, however, that the Depositary and any Depositary's Agent
agree to comply with all information reporting and withholding requirements
applicable to each of them under law or this Deposit Agreement in their capacity
as such.

     Neither the Depositary (or its officers, directors, employees or agents)
nor any Depositary's Agent nor the Registrar makes any representation or has any
responsibility as to the validity of the registration statement pursuant to
which the Depositary Shares are registered under the Securities Act, the Stock,
the Depositary Shares or any instruments referred to therein or herein, or as to
the correctness of any statement made therein or herein; provided, however, that
the Depositary is responsible for its representations in this Deposit Agreement.

     The Depositary assumes no responsibility for the correctness of the
description that appears in the Receipts, which can be taken as a statement of
the Company summarizing certain provisions of this Deposit Agreement.
Notwithstanding any other provision herein or in the Receipts, the Depositary
makes no warranties or representations as to the validity, genuineness or
sufficiency of any Stock at any time deposited with the Depositary

                                       11

<PAGE>

hereunder or of the Depositary Shares, as to the validity or sufficiency of this
Deposit Agreement, as to the value of the Depositary Shares or as to any right,
title or interest of the record holders of Receipts in and to the Depositary
Shares except that the Depositary hereby represents and warrants as follows: (i)
the Depositary has been duly organized and is validly existing and in good
standing under the laws of the State of [__________], with full power,
authority and legal right under such law to execute, deliver and carry out the
terms of this Deposit Agreement; (ii) this Deposit Agreement has been duly
authorized, executed and delivered by the Depositary; and (iii) this Deposit
Agreement constitutes, and when executed and delivered, each Receipt will
constitute, a valid and binding obligation of the Depositary, enforceable
against the Depositary in accordance with its terms, except as enforcement
thereof may be limited by bankruptcy, insolvency, reorganization or other
similar laws affecting enforcement of creditors' rights generally and except as
enforcement thereof is subject to general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law). The
Depositary shall not be accountable for the use or application by the Company of
its proceeds from the Depositary Shares or the Receipts.

     SECTION 5.4 RESIGNATION AND REMOVAL OF THE DEPOSITARY, APPOINTMENT OF
SUCCESSOR DEPOSITARY. The Depositary may at any time resign as Depositary
hereunder by written notice to the Company of its election to do so, such
resignation to take effect upon the appointment of a successor Depositary and
its acceptance of such appointment as hereinafter provided.

     The Depositary may at any time be removed by the Company by written notice
to the Depositary of such removal, such removal to take effect upon the
appointment of a successor depositary and its acceptance of such appointment as
hereinafter provided.

     In case at any time the Depositary acting hereunder shall resign or be
removed, the Company shall, within 60 days after the delivery of the notice of
resignation or removal, as the case may be, appoint a successor depositary,
which shall be a bank or trust company, or an affiliate of a bank or trust
company, having its principal office in the United States of America and having
a combined capital and surplus of at least $50,000,000. If a successor
depositary shall not have been appointed in 60 days, the resigning or removed
Depositary may petition a court of competent jurisdiction to appoint a successor
depositary. Every successor depositary shall execute and deliver to its
predecessor and to the Company an instrument in writing accepting its
appointment hereunder, and thereupon such successor depositary, without any
further act or deed, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor and for all purposes shall be the
Depositary under this Deposit Agreement, and such predecessor, upon payment of
all sums due it and on the written request of the Company, shall promptly
execute and deliver an instrument transferring to such successor all rights and
powers of such predecessor hereunder, shall duly assign, transfer and deliver
all rights, title and interest in the Stock and any moneys or property held
hereunder to such successor and shall deliver to such successor a list of the
record holders of all outstanding Receipts. Any successor Depositary shall
promptly mail notice of its appointment to the record holders of Receipts.

     Any corporation into or with which the Depositary may be merged,
consolidated or converted shall be the successor of such Depositary without the
execution or filing of any document or any further act. Such successor
Depositary may execute the Receipts either in the name of the predecessor
Depositary or in the name of the successor Depositary.

     SECTION 5.5 CORPORATE NOTICES AND REPORTS. The Company agrees that it will
deliver to the Depositary, and the Depositary will, promptly after receipt
thereof, transmit to the record holders of Receipts, in each case at the address
recorded in the Depositary's books or the books of any Depositary's Agent or the
Registrar, copies of all notices and reports (including financial statements)
required by law, by the rules of any national securities exchange upon which the
Stock, the Depositary Shares or the Receipts are listed or by the Certificate of
Incorporation or the applicable Certificate of Designation to be furnished by
the Company to holders of Stock. Such transmission will be at the Company's
expense and the Company will provide the Depositary with such number of copies
of such documents as the Depositary may reasonably request. In addition, the
Depositary will transmit to the record holders of Receipts at the Company's
expense such other documents as may be requested by the Company.

     SECTION 5.6 DEPOSIT OF STOCK BY THE COMPANY. The Company agrees with the

     SECTION 5.7 INDEMNIFICATION BY THE COMPANY. The Company shall indemnify the
Depositary for, and hold it harmless against, any loss, liability, claim or
expense ("Loss") arising out of or in connection with its duties under this

                            AMENDMENT AND TERMINATION

     SECTION 6.1 AMENDMENT. The form of the Receipts and any provision of this
Deposit Agreement may at any time and from time to time be amended by agreement
between the Company and the Depositary in any respect that they may deem
necessary or desirable, including to reflect the terms of any Certificate of
Designation; provided, however, that no such amendment that shall materially and
adversely alter the rights of the holders of Receipts shall be effective as to
outstanding Receipts until the expiration of 90 days after notice of such
amendment shall have been given to the record holders of outstanding Receipts.
Each holder of an outstanding Receipt at the time any such amendment becomes
effective shall be deemed, by continuing to hold such Receipt, to consent and
agree to such amendment and to be bound by this Deposit Agreement as amended
thereby. In no event shall any amendment impair the right, subject to the
provisions of this Deposit Agreement, of any holder of any Depositary Shares to
surrender the Receipt evidencing such Depositary Shares with instructions to the
Depositary to deliver to the holder the Stock or to cause the conversion of such
Stock into the Company's common stock or other securities in accordance with the
applicable Certificate of Designation and to deliver all securities, money and
other property, if any, represented thereby, except in order to comply with
mandatory provisions of applicable law.

     SECTION 6.2 TERMINATION. This Deposit Agreement may be terminated by either
the Company or the Depositary, upon notice to the other, only if (i) all of the
outstanding Depositary Shares have been redeemed or converted for any other
securities into which the Stock is convertible, or (ii) there has been a final
distribution of the Stock to the holders of Receipts in connection with the
Company's liquidation, dissolution or winding up. The Depositary will mail
notice of such termination to the record holders of all Receipts then
outstanding at least 30 days prior to the date fixed in such notice for such
termination. If any Receipts shall remain outstanding after the date of
termination of this Deposit Agreement, the Depositary thereafter shall
discontinue the transfer of Receipts, and shall not give any further notices or
perform any further acts under this Deposit Agreement, except that the
Depositary shall continue to deliver the Stock and any money and other property
represented by Receipts, without liability for interest thereon, upon surrender
thereof by the holders thereof, and the Depositary shall be discharged from all
obligations under this Deposit Agreement except to account for such Stock, money
and other property. Upon the termination of this Deposit Agreement, the Company
shall be discharged from all obligations under this Deposit Agreement except for
its obligations to the Depositary, any Depositary's Agent and any Registrar
under Sections 5.7 and 5.8.

                                   ARTICLE VII

when so executed and delivered, shall be deemed

                                       13

the same instrument. Delivery of an executed counterpart of a signature page to
this Deposit Agreement by telecopier shall be effective as delivery of a
manually executed counterpart of this Deposit Agreement. Copies of this Deposit
Agreement shall be filed with the Depositary and the Depositary's Agents and
shall be open to inspection during business hours at the Corporate Office and
the respective offices of the Depositary's Agents, if any, by any holder of a
Receipt.

     SECTION 7.2 EXCLUSIVE BENEFITS OF PARTIES. This Deposit Agreement is for
the exclusive benefit of the parties hereto, and their respective successors
hereunder, and shall not be deemed to give any legal or equitable right, remedy
or claim to any other person whatsoever.

     SECTION 7.3 INVALIDITY OF PROVISIONS. In case any one or more of the
provisions contained in this Deposit Agreement or in the Receipts should be or
become invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein or therein shall
in no way be affected, prejudiced or disturbed thereby.

     SECTION 7.4 NOTICES. Any notices to be given to the Company hereunder or
under the Receipts shall be in writing and shall be deemed to have been duly
given if personally delivered or sent by mail (first class postage prepaid), by
a nationally recognized overnight courier service, or by telecopier confirmed by
letter, addressed to the Company at 185 Berry Street, Suite 6504, San Francisco,
California 94107, Attention: General Counsel, or at any other place to which the
Company may have transferred its principal executive office.

overnight courier service, or by telecopier confirmed by letter, addressed to
the Depositary at the Corporate Office.

     Except as provided in the next paragraph, any notices given to any record
holder of a Receipt hereunder or under the Receipts shall be in writing and
shall be deemed to have been duly given if personally delivered or sent by mail
(first class postage), by a nationally recognized overnight courier service or
by telecopier confirmed by letter, addressed to such record holder at the
address of such record holder as it appears on the books of the Depositary or,
if such holder shall have filed with the Depositary a written request that
notices intended for such holder be mailed to some other address, at the address
designated in such request.

     In addition, whenever the Certificate of Designation requires any notice to
be published, the Depositary will, if requested by the Company, cause such
notice to be published in the manner directed by the Company.

     Delivery of a notice sent by mail, by overnight courier or by telecopier
shall be deemed to be effected at the time when a duly addressed letter
containing the same (or a duly addressed letter confirming an earlier notice in
the case of a telecopier message) is deposited, postage prepaid, in a post
office letter box or with the overnight courier service. The Depositary or the
Company may, however, act upon any telecopier message received by it from the
other or from any holder of a Receipt, notwithstanding that such telecopier
message shall not subsequently be confirmed by letter as aforesaid.

     SECTION 7.5 DEPOSITARY'S AGENTS. The Depositary may, with the approval of
the Company which approval shall not be unreasonably withheld, from time to time
appoint one or more Depositary's Agents to act in any respect for the Depositary
for the purposes of this Deposit Agreement and may vary or terminate the
appointment of such Depositary's Agents.

     SECTION 7.6 HOLDERS OF RECEIPTS ARE PARTIES. Notwithstanding that holders
of Receipts have not executed and delivered this Deposit Agreement or any
counterpart thereof, the holders of Receipts from time to time shall be deemed
to be parties to this Deposit Agreement and shall be bound by all of the terms
and conditions, and be entitled to all of the benefits, hereof and of the
Receipts by acceptance of delivery of Receipts.

     SECTION 7.7 GOVERNING LAW. This Deposit Agreement and the Receipts and all
rights hereunder and thereunder and provisions hereof and thereof shall be
governed by, and construed in accordance with, the law of the State of New York
without giving effect to principles of conflict of laws.

[REVERSE OF DEPOSITARY RECEIPT]

1. THE DEPOSIT AGREEMENT. Receipts, of which this Receipt is one, are made
available upon the terms and conditions set forth in the Deposit Agreement,
dated as of [     ] (the "Deposit Agreement"), among the Company, the Depositary
and all holders from time to time of Receipts. The Deposit Agreement (copies of
which are on file at the Corporate Office and at the office of any agent of the
Depositary) sets forth the rights of holders of Receipts and the rights and
duties of the Depositary. The statements made on the face and the reverse of
this Receipt are summaries of certain provisions of the Deposit Agreement and
are subject to the detailed provisions thereof, to which reference is hereby
made. In the event of any conflict between the provisions of this Receipt and
the provisions of the Deposit Agreement, the provisions of the Deposit Agreement
will govern.

2. DEFINITIONS. Unless otherwise expressly herein provided, all defined terms
used herein shall have the meanings ascribed thereto in the Deposit Agreement.

3. REDEMPTION BY THE COMPANY; REPURCHASE BY THE COMPANY. Whenever the Company
shall redeem shares of Stock in accordance with a Certificate of Designation, it
shall (unless otherwise agreed in writing with the Depositary) give the
Depositary in its capacity as Depositary not less than 3 business days' prior
notice of the proposed date of the mailing of a notice of redemption of Stock
and the simultaneous redemption of the Depositary Shares representing the Stock
to be redeemed and of the number of such shares of Stock held by the Depositary
to be redeemed. Unless the Certificate of Designation for a specific series of
Stock provides for a different notice period with respect to that Stock in the
event of its redemption, the Depositary shall, as directed by the Company in
writing, mail, first class postage prepaid, notice of the redemption not less
than 30 and not more than 60 days prior to the date fixed for redemption of such
Stock and Depositary Shares, to the record holders of the Receipts evidencing
the Depositary Shares to be so redeemed, at the addresses of such holders as the
same appear on the records of the Depositary or any Depositary's Agent or
Registrar. Notwithstanding the foregoing, neither failure to mail or publish any
such notice to one or more such holders nor any defect in any notice shall
affect the sufficiency of the proceedings for redemption. On the date of any
such redemption, the Depositary shall surrender the certificate or certificates
held by the Depositary evidencing the number of shares of Stock to be redeemed
in the manner specified in the notice of redemption. The Depositary shall,
thereafter, redeem the number of Depositary Shares representing such redeemed
Stock upon the surrender of Receipts evidencing such Depositary Shares in the
manner provided in the notice sent to record holders of Receipts. Notice having
been mailed as aforesaid, from and after the redemption date (unless the Company
shall have failed to redeem the shares of Stock to be redeemed by it upon the
surrender of the certificate or certificates therefore by the Depositary as
described above), the Depositary Shares called for redemption shall be deemed
no longer to be outstanding and all rights of the holders of Receipts evidencing
such Depositary Shares (except the right to receive the cash, securities or
other property payable upon redemption upon surrender of such Receipts) shall,
to the extent of such Depositary Shares, cease and terminate. The foregoing
shall be subject further to the terms and conditions of the applicable
Certificate of Designation.

     Whenever the Company shall be required to make an offer to repurchase
Depositary Shares in accordance with a Certificate of Designation, it shall
(unless otherwise agreed in writing with the Depositary) give the Depositary in
its capacity as Depositary not less than 3 business days' prior notice of the
required date of the mailing of a notice of the repurchase offer. The Depositary
shall, as directed by the Company in writing, mail, first class postage prepaid,
notice of the relevant terms of the repurchase offer, as provided by the
Company, to the record holders of the Receipts at the addresses of such holders
as the same appear on the records of the Depositary or any Depositary's Agent or
Registrar. The Depositary shall, thereafter, receive from each holder electing
to have Depositary Shares repurchased pursuant to the repurchase offer in
accordance with the instructions in the notice, the holder's Receipts, with an
appropriate form duly completed prior to the repurchase date. In case the
aggregate number of Depositary Shares offered for repurchase by the holders
exceeds the amount of Depositary Shares which the Company has offered to
repurchase pursuant to the repurchase offer, the Depositary Shares to be
repurchased shall be selected by the Depositary by lot or proportionately, as
may be determined by the Depositary. The foregoing is subject further to the
terms and conditions of the applicable Certificate of Designation.

4. CONVERSION. In the event that the Stock, in accordance with its Certificate
of Designation, is convertible into the Company's common stock or other
securities, subject to the terms and conditions of the Deposit Agreement, a
holder of a Receipt or Receipts may surrender such Receipt or Receipts at the
Corporate Office or at such other office or to a Depositary's Agent that the
Depositary may designate for such purpose, together with a notice of

                                       18

<PAGE>

conversion duly completed and executed, thereby directing the Depositary or such
Depositary's Agent to instruct the Company to cause the conversion of the number
of shares of Stock specified in such notice of conversion into shares of the
Company's common stock or other securities at the rate specified in the
applicable Certificate of Designation, and an assignment of such Receipt or
Receipts to the Company or in blank, duly completed and executed, along with any
other documents or instruments and any amounts required by the applicable
Certificate of Designation.

     Upon receipt by the Depositary or a Depositary's Agent of a Receipt or
Receipts of such notice, assignment and other documents, instruments or amounts,
the Depositary or such Depositary's Agent shall instruct the Company, subject to
any adjustment provided for in the applicable Certificate of Designation, (i) to
cause the conversion at the rate specified in the applicable Certificate of
Designation of the number of shares of Stock evidenced by the Receipt or
Receipts so surrendered for conversion as specified in the written notice to the
Depositary or such Depositary's Agent and (ii) to cause the delivery to the
holder of such Receipt or Receipts of (a) a certificate or certificates
evidencing the number of whole shares of the Company's common stock or other
securities into which such Stock has been converted, and (b) the amount of cash
or other property, if any, to which such holder is entitled in lieu of
fractional shares of, or fractional interests in, the Company's common stock or
other securities otherwise deliverable by the Company upon such conversion,
calculated in accordance with the applicable Certificate of Designation. Upon
such conversion, the Depositary or such Depositary's Agent (i) shall deliver to
the holder a Receipt evidencing the number of Depositary Shares evidenced by the
surrendered Receipt or Receipts in excess of the number of Depositary Shares
evidenced by such Receipt or Receipts that have been so converted, (ii) shall
cancel the Receipts surrendered for conversion and (iii) shall deliver to the
Company for cancellation the number of shares of Stock evidenced by the Receipts
so surrendered and so converted.

     Upon the conversion of any Stock for which a notice of conversion has been
provided to the Depositary or a Depositary's Agent by the holder of the Receipt
or Receipts representing such Stock, the Depositary Shares evidenced by such
Receipt or Receipts shall be deemed no longer outstanding, all rights of the
holder of the Receipt or Receipts evidencing such Depositary Shares (except the
right to receive (i) the Company's common stock or other securities to which
such holder is entitled upon conversion in accordance with the applicable
Certificate of Designation, (ii) any cash or other property payable in
accordance with the applicable Certificate of Designation with respect to any
fractional shares or other fractional interests in the Company's common stock or
other securities otherwise deliverable by the Company upon conversion, (iii) any
Receipts evidencing Depositary Shares representing Stock which was not so
converted and (iv) any other securities, property or cash to which such holder
is entitled under this Deposit Agreement) shall cease and terminate, and the
Receipt or Receipts evidencing such Depositary Shares shall be cancelled.

     No fractional shares or other fractional interests in the Company's common
stock or other securities shall be deliverable by the Company upon conversion of
the Stock represented by the Depositary Shares.

5. WITHDRAWAL OF STOCK. Holders of Receipts shall have the right, upon payment
of any amount due to the Depositary with respect to the Receipts, to withdraw
any or all of the Stock (but only in whole shares of Stock) represented by the
Depositary Shares and all money and other property, if any, represented by such
Depositary Shares by surrendering the Receipt or Receipts evidencing such
Depositary Shares at the Corporate Office, or at such other offices as the
Depositary may designate for such withdrawal (and cancellation of the
surrendered Receipts as provided in the Deposit Agreement).

6. TRANSFERS, SPLIT-UPS, COMBINATIONS. Subject to Paragraphs 7, 8 and 9 below,
this Receipt is transferable on the books of the Depositary upon surrender of
this Receipt to the Depositary at the Corporate Office or at such other offices
as the Depositary may designate for such purchase, properly endorsed or
accompanied by a properly executed instrument of transfer, together with
evidence of the payment of any transfer taxes as may be required by law, and
upon such transfer the Depositary shall execute and deliver a Receipt or
Receipts to or upon the order of the person entitled thereto, all as provided in
and subject to the Deposit Agreement. Subject to the Deposit Agreement, this
Receipt may be split into other Receipts or combined with other Receipts into
one Receipt evidencing the same aggregate number of Depositary Shares evidenced
by the Receipt or Receipts surrendered; provided, however, that the Depositary
shall not issue any Receipt evidencing a fractional Depositary Share.

7. CONDITIONS TO SIGNING AND DELIVERY, TRANSFER, ETC., OF RECEIPTS.

Prior to the execution and delivery, registration of transfer, split-up,
combination, or surrender of this Receipt, the delivery of any distribution
hereon or withdrawal or deposit of the Stock evidenced hereby, or the exercise

<PAGE>

applicable conversion right, the Depositary, any of the Depositary's Agents, the
Registrar or the Company may require any or all of the following:

(i) payment to it of a sum sufficient for the payment (or, in the event that the
Depositary or the Company shall have made such payment, the reimbursement to it)

or with respect to other property of the Company being issued upon redemption or
conversion); (ii) production of proof satisfactory to it as to the identity and
genuineness of any signature; and (iii) compliance with such reasonable

representations and warranties as the Depositary or the Company may reasonably
deem necessary or proper. The Depositary or the Company may withhold or delay
the delivery of this Receipt, the registration of transfer or redemption of this

evidenced by this Receipt upon its surrender or the exercise of any applicable
conversion right may be refused, any dividend or other distribution may be

outstanding Receipt at the time any such amendment becomes effective shall be
deemed, by continuing to hold such Receipt, to consent and agree to such
amendment and to be bound by the Deposit Agreement as amended thereby. In no
event shall any amendment impair the right, subject to the provisions of the

to the holder the Stock or to cause the conversion of such Stock into the
Company's common stock or other securities in accordance with the applicable

holder hereof by accepting or holding the same consents and agrees, that title
to this Receipt (and to the Depositary Shares evidenced hereby), when properly
endorsed or accompanied by a properly executed instrument of transfer, is
transferable by delivery with the same effect as in the case of investment
securities in general; provided, however, that the Depositary may,
notwithstanding any notice to the contrary, treat the record holder hereof at
such time as the absolute owner hereof for the purpose of determining the person
entitled to distribution of dividends or other distributions or to any notice
provided for in the Deposit Agreement and for all other purposes.

13. DIVIDENDS AND DISTRIBUTIONS. Whenever the Depositary shall receive any cash
dividend or other cash distribution on the Stock (other than cash dividends or

deliverable by the Company in accordance with the applicable Certificate of
Designation), the Depositary shall, subject to the provisions of the Deposit
Agreement, distribute to record holders of Receipts on the record date fixed
pursuant to paragraph 15 such amounts of such sums as are, as nearly as
practicable, in proportion to the respective numbers of Depositary Shares
evidenced by the Receipts held by such holders; provided, however, that in case
the Company or the Depositary shall be required by law to withhold and does
withhold from any cash dividend or other cash distribution in respect of the
Stock an amount on account of taxes, the amount made available for distribution
or distributed in respect of Depositary Shares shall be reduced accordingly. The
Depositary shall distribute or make available for distribution, as the case may
be, only such amount, however, as can be distributed without attributing to any
holder of Depositary Shares a fraction of one cent and any balance not so
distributable shall be held by the Depositary (without liability for interest
thereon) and shall be added to and be treated as part of the next sum received
by the Depositary for distribution to record holders of Receipts then
outstanding.

14. SUBSCRIPTION RIGHTS, PREFERENCES OR PRIVILEGES. If the Company shall at any
time offer or cause to be offered to the persons in whose name Stock is
registered on the books of the Company any rights, preferences or privileges to
subscribe for or to purchase any securities or any rights, preferences or
privileges of any other nature, such rights, preferences or privileges shall in
each such instance, subject to the provisions of the Deposit Agreement, be made
available by the Depositary to the record holders of Receipts in such manner as
the Company shall instruct.

15. NOTICE OF DIVIDENDS, FIXING OF RECORD DATE. Whenever (i) any cash dividend
or other cash distribution shall become payable, or any distribution other than
cash shall be made, or any rights, preferences or privileges shall at any time
be offered, with respect to the Stock, or (ii) the Depositary shall receive
notice of any meeting at which holders of Stock are entitled to vote or of which
holders of Stock are entitled to notice, or (iii) of any mandatory conversion
of, or any election on the part of the Company to call for redemption or
exchange of, any shares of Stock, in accordance with the applicable Certificate
of Designation or otherwise, the Depositary shall in each such instance fix a
record date (which shall be the same date as the record date fixed by the
Company with respect to the Stock) for the determination of the holders of
Receipts (x) who shall be entitled to receive such dividend, distribution,
rights, preferences or privileges or the net proceeds of the sale thereof, or
(y) who shall be entitled to give instructions for the exercise of voting rights
at any such meeting or to receive notice of such meeting or of such conversion,
exchange or redemption.

16. VOTING RIGHTS. Upon receipt of notice of any meeting at which the holders of
Stock are entitled to vote, the Depositary shall, as soon as practicable
thereafter, mail to the record holders of Receipts a notice, which shall contain
(i) such information as is contained in such notice of meeting, (ii) a statement
that the holders of Receipts at the close of business on a specified record date
determined as provided in paragraph 15 will be entitled, subject to any
applicable provision of law, the Certificate of Incorporation or the applicable
Certificate of Designation, to instruct the Depositary as to the exercise of the
voting rights pertaining to the Stock represented by their respective Depositary
Shares, and (iii) a brief statement as to the manner in which such instructions
may be given. Upon the written request of a holder of this Receipt on such
record date, the Depositary shall endeavor insofar as practicable to vote or
cause to be voted the Stock represented by the Depositary Shares evidenced by
this Receipt in accordance with the instructions set forth in such request. The
Company hereby agrees to take all reasonable action that may be deemed necessary
by the Depositary in order to enable the Depositary to vote such Stock or
cause such Stock to be voted. In the absence of specific instructions from the
holder of this Receipt, the Depositary will abstain from voting to the extent of
the Stock represented by the Depositary Shares evidenced by this Receipt.

17. REPORTS, INSPECTION OF TRANSFER BOOKS. The Company agrees that it will
deliver to the Depositary, and the Depositary will, promptly after receipt
thereof, transmit to the record holders of Receipts, in each case at the address

Registrar, copies of all notices and reports (including financial statements)
required by law, by the rules of any national securities exchange upon which the
Stock, the Depositary Shares or the Receipts are listed or by the Certificate of
Incorporation or the applicable Certificate of Designation to be furnished by
the Company to holders of Stock. The Depositary, acting as transfer agent and
Registrar, shall keep books at the Corporate Office for the registration and
transfer of Receipts, which books at all reasonable times shall be open for

requesting to exercise such right shall certify to the Depositary that such
inspection shall be for a proper purpose reasonably related to such person's
interest as an owner of Depositary Shares.

performed or (ii) by reason of any exercise of, or failure to exercise, any
discretion provided for in the Deposit Agreement except, in the case of the
Depositary, any Depositary's Agent or the Registrar, if such exercise or failure
to exercise discretion is caused by its negligence or willful misconduct.

19. OBLIGATIONS OF THE DEPOSITARY, THE DEPOSITARY'S AGENT, THE REGISTRAR AND THE
COMPANY. The Company assumes no obligation and shall be subject to no liability
under the Deposit Agreement or this Receipt to the holder hereof or other

presenting Stock for deposit, any holder of this Receipt or any other person
believed by it in good faith to be competent to give such advice or information.
