the Purchase Contract comprising a portion of such Corporate PIES.

Intermediary (provided that in the event such payment is received by the

New York City time, on a Business Day, then such payment shall be made no later

(ii) in the case of Proceeds from the Remarketing with respect to any of the
Pledged Preferred Stock or security entitlements thereto, to the Company on the

Stock is a part under the Purchase Contracts forming a part of such Corporate
PIES. Dividends on any Preferred Stock forming part of a Corporate PIES

Certificate (or a Predecessor Corporate PIES Certificate) is registered at the
close of business on the Record Date for such Payment Date.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate PIES Certificate to purchase, and the Company to sell, on August 16,
2002 (the "Purchase Contract Settlement Date"), at a price equal to $50 in cash
(the "Stated Amount"), a number of Common Shares, par value $0.01 ("Common
Stock"), of the Company, equal to the Settlement Rate, unless on or prior to the
Purchase Contract Settlement Date there shall have occurred a Termination Event
or an Early Settlement with respect to the Corporate PIES of which such Purchase
Contract is a part, all as provided in the Purchase Contract Agreement and more
fully described on the reverse hereof. The purchase price (the "Purchase Price")
for the shares of Common Stock purchased pursuant to each Purchase Contract
evidenced hereby, if not paid earlier, shall be paid on the Purchase Contract
Settlement Date by separate cash or by application of payment received, pursuant
to the Remarketing, in respect of the liquidation preference with respect to any
Pledged Preferred Stock pledged to secure the obligations under such Purchase
Contract of the Holder of the Corporate PIES of which such Purchase Contract is
a part.

     The Company shall pay, on each Payment Date, in respect of each Purchase
Contract forming part of a Corporate PIES evidenced hereby an amount (the
"Contract Adjustment Payments") equal to (a) if a Reset Transaction has not
occurred, 0.75% per annum of the Stated Amount or (b) following the occurrence
of a Reset Transaction, the Adjusted Contract Adjustment Payment Rate related to
such Reset Transaction until any such succeeding Reset Transaction shall occur

twelve 30-day months and (ii) for any period shorter than a full quarterly
period, a 30-day


                                                                          3

per 30-day period).  Such Contract  Adjustment  Payments  shall be payable  to
the  Person in whose  name this  Corporate  PIES  Certificate  (or a Predecessor
Corporate PIES  Certificate) is registered at the close of business on the
Record Date for such Payment Date.

     Dividends on the Preferred Stock and Contract Adjustment Payments will be
payable at the office of the Agent in The City of New York or, at the option of
the Company, by check mailed to the address of the Person entitled thereto as
such address appears on the Corporate PIES Register.

hereof, which further provisions shall for all purposes have the same effect as
if set forth at this place.

Agent by manual signature, this Corporate PIES Certificate shall not be entitled

                 (FORM OF REVERSE OF CORPORATE PIES CERTIFICATE)


     Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of August 10, 1999 (as may be supplemented from time to
time, the "Purchase Contract Agreement"), between the Company and The First
National Bank of Chicago, as Purchase Contract Agent (including its successors
hereunder, the "Agent"), to which Purchase Contract Agreement and supplemental
agreements thereto reference is hereby made for a description of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Agent, the Company, and the Holders and of the terms upon which the
Corporate PIES Certificates are, and are to be, executed and delivered.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate PIES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price"), a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part or an Early Settlement shall have
occurred. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $44.9250 (the "Threshold
Appreciation Price"), 1.11297 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price but
is greater than $37.4375 the number of shares of Common Stock per Purchase
Contract equal to the Stated Amount divided by the Applicable Market Value and
(c) if the Applicable Market Amount is less than or equal to $37.4375, 1.33556
shares of Common Stock per Purchase Contract, in each case subject to adjustment
as provided in the Purchase Contract Agreement. No fractional shares of Common
Stock will be issued upon settlement of Purchase Contracts, as provided in the
Purchase Contract Agreement.

     Each Purchase Contract evidenced hereby, which is settled either through
Early Settlement or Cash Settlement, shall obligate the Holder of the related
Corporate PIES to purchase at the Purchase Price, and the Company to sell, a
number of newly issued shares of Common Stock equal to the Early Settlement Rate
or the Settlement Rate, as applicable.

     The "Applicable Market Value" means the average of the Closing Price per
share of Common Stock on each of the 20 Trading Days ending on the third Trading
Day immediately preceding the Purchase Contract Settlement Date. The "Closing
Price" of the Common Stock on any date of determination means (i) the closing
sale price (or, if no closing price is reported, the last reported sale price)
of the Common Stock on the Nasdaq National Market on such date, (ii) if the
Common Stock is not listed for trading on the Nasdaq National Market on any such
date, the closing sale price as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, (iii) if the Common Stock is not so reported, the last quoted bid price
for the Common Stock in the over-the-counter market as reported by the National
Quotation Bureau or similar organization or (iv) if such bid price is not
available, the average of the mid-point of the last bid and ask prices of the
Common Stock on such date from at least three nationally recognized independent
investment banking firms


                                                                          6



retained for this purpose by the Company. A "Trading Day" means a day on
which the Common Stock (A) is not suspended from trading on any national or
regional securities exchange or association or over-the-counter market at the
close of business and (B) has traded at least once on the national or regional
securities exchange or association or over-the-counter market that is the
primary market for the trading of the Common Stock.

     In accordance with the terms of the Purchase Contract Agreement, the Holder
of this Corporate PIES Certificate may pay the Purchase Price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby by
effecting a Cash Settlement or an Early Settlement or a remarketing of the
related Pledged Preferred Stock. A Holder of Corporate PIES who does not effect,
on or prior to 11:00 a.m. New York City time on the fifth Business Day
immediately preceding the Purchase Contract Settlement Date, an effective Cash
Settlement or an Early Settlement, shall pay the Purchase Price for the shares
of Common Stock to be issued under the related Purchase Contract from the
proceeds of the sale of the related Pledged Preferred Stock held by the
Collateral Agent. Such sale will be made by the Remarketing Agent pursuant to
the terms of the Remarketing Agreement on the third Business Day prior to the
Purchase Contract Settlement Date. If, as provided in the Purchase Contract
Agreement, upon the occurrence of a Failed Remarketing the Collateral Agent, for
the benefit of the Company, exercises its rights as a secured creditor with
respect to the Pledged Preferred Stock related to this Corporate PIES
certificate, any accrued and unpaid dividends on such Pledged Preferred Stock
will become payable by the Company to the holder of this Corporate PIES
Certificate in the manner provided for in the Purchase Contract Agreement.

     The Company shall not be obligated to issue any shares of Common Stock in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the shares of Common Stock to be purchased thereunder in the manner herein set
forth.

     Each Purchase Contract evidenced hereby and all obligations and rights of
the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Agent and to the Holders, at their addresses as they
appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Preferred
Stock forming a part of each Corporate PIES from the Pledge. A Corporate PIES
shall thereafter represent the right to receive the Preferred Stock forming a
part of such Corporate PIES in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement.

     Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Preferred Stock. Upon receipt of notice of any meeting at which holders of
Preferred Stock are entitled to vote or upon the solicitation of consents,
waivers or proxies of holders of Preferred Stock, the Agent shall, as soon as
practicable thereafter, mail to the Corporate PIES Holders a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Corporate PIES Holder on the record date set by the Agent
therefor (which, to the extent possible, shall be the same date as the record
date for determining the holders of Preferred Stock entitled to vote) shall


                                                                          7


be entitled to instruct the Agent as to the exercise of the voting rights
pertaining to the Preferred Stock constituting a part of such Holder's Corporate
PIES and (c) stating the manner in which such instructions may be given. Upon
the written request of the Corporate PIES Holders on such record date, the Agent
shall endeavor insofar as practicable to vote or cause to be voted, in
accordance with the instructions set forth in such requests, the maximum
aggregate liquidation preference of Preferred Stock as to which any particular
voting instructions are received. In the absence of specific instructions from
the Holder of a Corporate PIES, the Agent shall abstain from voting the
Preferred Stock evidenced by such Corporate PIES.

     The Corporate PIES Certificates are issuable only in registered form and
only in denominations of a single Corporate PIES and any integral multiple
thereof. The transfer of any Corporate PIES Certificate will be registered and
Corporate PIES Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Corporate PIES Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. A holder who elects to
substitute a Treasury Security for Preferred Stock thereby creating Treasury
PIES, shall be responsible for any fees or expenses payable in connection
therewith. Except as provided in the Purchase Contract Agreement, for so long as
the Purchase Contract underlying a Corporate PIES remains in effect, such
Corporate PIES shall not be separable into its constituent parts, and the rights
and obligations of the Holder of such Corporate PIES in respect of the Preferred
Stock and Purchase Contract constituting such Corporate PIES may be transferred
and exchanged only as a Corporate PIES. The holder of a Corporate PIES may
substitute for the Pledged Preferred Stock securing its obligation under the
related Purchase Contract Treasury Securities in an aggregate principal amount
equal to the aggregate liquidation preference of the Pledged Preferred Stock in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement. From and after such Collateral Substitution, the Security for which
such Pledged Treasury Securities secures the holder's obligation under the
Purchase Contract shall be referred to as a "Treasury PIES." A Holder may make
such Collateral Substitution only in integral multiples of 20 Corporate PIES for
20 Treasury PIES. Such Collateral Substitution may cause the equivalent
aggregate amount of this Certificate to be increased or decreased; provided,
however, this Corporate PIES Certificate shall not represent more than 2,000,000
Corporate PIES. All such adjustments to the equivalent amount of this Corporate
PIES Certificate shall be duly recorded by placing an appropriate notation on
the Schedule attached hereto.

     A Holder of Treasury PIES may recreate Corporate PIES by delivering to the
Securities Intermediary Preferred Stock with an aggregate liquidation preference
equal to the aggregate principal amount of the Pledged Treasury Securities in
exchange for the release of such Pledged Treasury Securities in accordance with
the terms of the Purchase Contract Agreement and the Pledge Agreement.

     The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name the Corporate PIES Certificate evidencing such Purchase Contract is
registered at the close of business on the Record


                                                                          8



Date for such Payment Date. Contract Adjustment Payments will be payable at the
office of the Agent in The City of New York or, at the option of the Company, by
check mailed to the address of the Person entitled thereto at such address as it
appears on the Corporate PIES Register.

     The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder, including, without limitation, the rights of the Holders
to receive and the obligation of the Company to pay any Contract Adjustment
Payments, shall immediately and automatically terminate, without the necessity
of any notice or action by any Holder, the Agent or the Company, if, on or prior
to the Purchase Contract Settlement Date, a Termination Event shall have
occurred. Upon the occurrence of a Termination Event, the Company shall promptly
but in no event later than two Business Days thereafter give written notice to
the Agent, the Collateral Agent and the Holders, at their addresses as they
appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Preferred Stock from
the Pledge in accordance with the provisions of the Pledge Agreement.

     Subject to and upon compliance with the provisions of the Purchase Contract
Agreement, at the option of the Holder thereof, Purchase Contracts underlying
Securities may be settled early (an "Early Settlement") as provided in the
Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Corporate
PIES Certificate, the Holder of this Corporate PIES Certificate shall deliver
this Corporate PIES Certificate to the Agent at the Corporate Trust Office duly
endorsed for transfer to the Company or in blank with the form of Election to
Settle Early set forth below duly completed and accompanied by payment in the
form of immediately available funds payable to the order of the Company in an
amount (the "Early Settlement Amount") equal to (i) the product of (A) the
Stated Amount times (B) the number of Purchase Contracts with respect to which
the Holder has elected to effect Early Settlement, plus (ii) if such delivery is
made with respect to any Purchase Contracts during the period from the close of
business on any Record Date for any Payment Date to the opening of business on
such Payment Date, an amount equal to the Contract Adjustment Payments payable
on such Payment Date with respect to such Purchase Contracts. Upon Early
Settlement of Purchase Contracts by a Holder of the related Securities, the
Pledged Preferred Stock underlying such Securities shall be released from the
Pledge as provided in the Pledge Agreement and the Holder shall be entitled to
receive a number of shares of Common Stock on account of each Purchase Contract
forming part of a Corporate PIES as to which Early Settlement is effected equal
to the Early Settlement Rate. The Early Settlement Rate shall initially be equal
to 1.11297 shares of Common Stock and shall be adjusted in the same manner and
at the same time as the Settlement Rate is adjusted as provided in the Purchase
Contract Agreement.

     Upon registration of transfer of this Corporate PIES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Corporate
PIES Certificate. The Company covenants and agrees, and the Holder, by its
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.


                                                                         9



     The Holder of this Corporate PIES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Corporate PIES evidenced hereby on its behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
his obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Purchase Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Shares underlying this
Corporate PIES Certificate pursuant to the Pledge Agreement. The Holder further
covenants and agrees that, to the extent and in the manner provided in the
Purchase Contract Agreement and the Pledge Agreement, but subject to the terms
thereof, Proceeds from the Remarketing with respect to any of the Pledged
Preferred Stock or security entitlements thereto in respect of the aggregate
liquidation preference of the Pledged Preferred Stock on the Purchase Contract
Settlement Date shall be paid by the Collateral Agent to the Company in
satisfaction of such Holder's obligations under such Purchase Contract and such
Holder shall acquire no right, title or interest in such payments.

     Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

     The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.

     The Company, the Agent and its Affiliates and any agent of the Company or
the Agent may treat the Person in whose name this Corporate PIES Certificate is
registered as the owner of the Corporate PIES evidenced hereby for the purpose
of receiving payments of dividends payable quarterly on the Preferred Stock
receiving payments of Contract Adjustment Payments, performance of the Purchase
Contracts and for all other purposes whatsoever, whether or not any payments in
respect thereof be overdue and notwithstanding any notice to the contrary, and
neither the Company, the Agent nor any such agent shall be affected by notice to
the contrary.

        The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of shares of Common Stock.

        A copy of the Purchase Contract Agreement is available for inspection at
the offices of the Agent.



                                                                         10
