EXHIBIT 4.3

                                 AQUA DYNE, INC.
                             STOCK OPTION AGREEMENT

         AQUA DYNE, INC. (the "Company"), desiring to afford an opportunity to
the Grantee named below to purchase certain shares of the Company's Common
Stock, hereby grants to the Grantee, and the Grantee hereby accepts, an option
to purchase the number of such shares specified below, during a term ending at
midnight (prevailing local time at the Company's principal offices) on the
Expiration Date of this Option specified below, at the Option Exercise Price Per
Share specified below, subject to and upon the following terms and conditions:

         1. IDENTIFYING PROVISIONS. As used in this Option, the following terms
shall have the following respective meanings:

          (a)      Grantee:
          (b)      Date of Grant:
          (c)      Number of Shares of Common Stock Optioned:
          (d)      Option Exercise Price Per Share
          (e)      Expiration Date:

         2. NATURE OF THE OPTION. This Option is intended to be a non-statutory
stock option and is not intended to be an incentive stock option within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), or to otherwise qualify for any special tax benefits to the Grantee.

         3. RESTRICTIONS ON TRANSFERABILITY OF OPTION. This Option may not be
transferred by the Grantee other than by will or the laws of descent and
distribution and may be exercised during the Grantee's lifetime only by the
Grantee or the Grantee's guardian or legal representative. However, it may
during the Grantee's lifetime also be transferred to and may thereafter be
exercised by members of the Grantee's immediate family, or a partnership whose
members include only the Grantee and/or members of the Grantee's immediate
family, or a trust for the benefit of only the Grantee and/or members of the
Grantee's immediate family. As used herein, the Grantee's immediate family
includes only the Grantee's spouse, parents or other ancestors, and children and
other direct descendants of the Grantee or of the Grantee's spouse (including
such ancestors and descendants by adoption).

         4. ADJUSTMENTS AND CORPORATE REORGANIZATIONS. If the outstanding shares
of stock of the class then subject to this Option are increased or decreased, or
are changed into or exchanged for a different number or kind of shares or
securities or other forms of property (including cash) or rights, as a result of
one or more reorganizations, recapitalization, spin-offs, stock splits, reverse
stock splits, stock dividends or the like, appropriate adjustments shall be made
in the number and/or kind of shares or securities or other forms of property
(including cash) or rights for which this Option may thereafter be exercised,
all without any change in the aggregate exercise price applicable to the
unexercised portions of this Option, but with a corresponding adjustment in the
exercise price per share or other unit. No fractional share of stock shall be
issued under this Option or in connection with any such adjustment. Such
adjustments shall be

                                        1

<PAGE>

made by or under authority of the Company's board of directors whose
determinations as to what adjustments shall be made, and the extent thereof,
shall be final, binding and conclusive. In the event the Company is a party to
an agreement by which all outstanding shares of the Company's stock of the class
then subject to this Option are exchanged for shares of stock of another
corporation, the Company shall provide in such agreement that the Grantee shall
receive the options and/or other rights provided for by this Stock Option
Agreement.

         Upon the dissolution or liquidation of the Company, this Option shall
terminate, unless provision be made in writing in connection with such
transaction for the assumption of this Option, or the substitution for this
Option of an option covering the stock of a successor corporation, or a parent
or a subsidiary thereof, with appropriate adjustments in accordance with the
provisions hereinabove in this Section entitled "Adjustments and Corporate
Reorganizations" as to the number and kind of shares optioned and their exercise
prices, in which event this Option shall continue in the manner and under the
terms so provided.

         If this Option shall terminate pursuant to the next preceding
paragraph, the Grantee or other person then entitled to exercise this Option
shall have the right, at such time prior to the consummation of the transaction
causing such termination as the Company shall designate, to exercise the
unexercised portions of this Option, including the portions thereof which would,
but for this Section entitled "Adjustments and Corporate Reorganizations," not
yet be exercisable.

         5. EXERCISE, PAYMENT FOR AND DELIVERY OF STOCK. This Option may be
exercised by the Grantee or other person then entitled to exercise it by giving
four business days' written notice of exercise to the Company specifying the
number of shares to be purchased and the total purchase price, accompanied by a
check to the order of the Company in payment of such total purchase price and
the presentation and surrender of this Option Agreement. If the Company is
required to withhold on account of any federal, state or local tax imposed as a
result of such exercise, the notice of exercise shall also be accompanied by
check to the order of the Company in payment of the amount thus required to be
withheld.

         6. NON-CASH EXERCISE. Grantee may at its option elect to pay the
purchase price either with cash as described above or by receiving that number
of shares of common stock (as determined below) that is equal to the value (as
determined below) of this Option, in which event the Company shall issue to the
Grantee the number of shares of common stock determined by using the following
formula:
                                    X = Y (A-B)
                                        -------
                                         A
where X = the number of shares of common stock (or Option Shares) to be issued
to Grantee; Y = the number of Option Shares subject to this Option; A = the Fair
Market Value of one (1) Option Share; B = the Exercise Price per Option Share.

                  For purposes of the above provision, "Fair Market Value" means
the average of the daily closing prices for fifteen (15) consecutive trading
days commencing immediately before the date of such computation. The closing
price for each day shall be the last reported sales price regular way or in case
no such reported sale takes place on such day, the average of the closing bid
and asked prices regular way for such day, in either case on the principal
national securities

                                        2

<PAGE>

exchange on which the shares are listed or admitted to trading, of if they are
not listed or admitted to trading on any national securities exchange, but are
traded in the over-the-counter market, the closing sale price of the Common
Stock or, in case no sale is publicly reported, the average of the
representative closing bid and asked quotations for the Common Stock on the
National Association of Securities Dealers Automated Quotation ("NASDAQ") system
or any comparable system, or if the Common Stock is not listed on the NASDAQ
system or any comparable system, the closing price of the Common Stock or, in
case no sale is publicly reported, the average of the closing bid and asked
prices as furnished by two members of the National Association of Securities
Dealers selected from time to time by the Company for that purpose, or if there
are no closing bid and asked prices available, "Fair Market Value" shall be
determined by the Board of Directors appointing a valuation or investment
banking firm of national standing, acceptable to Grantee, who at the Company's
expense shall give their opinion as to what constitutes "Fair Market Value," in
each case as adjusted upon the application of Section 4 hereof.

         7. RIGHTS IN STOCK BEFORE ISSUANCE AND DELIVER. No person shall be
entitled to the privileges of stock ownership with respect to any shares
issuable upon exercise of this Option, unless and until such shares have been
issued to such person as fully paid shares.

         8. REQUIREMENTS OF LAW. By accepting this Option, the Grantee
represents and agrees for himself or herself and his or her transferees by will
or the laws of descent and distribution that, unless a registration statement
under the Securities Act of 1933 (the "Act") is in effect as to shares purchased
upon any exercise of this Option, (a) any and all shares so purchased shall be
acquired for his or her personal account and not with a view to or for sale in
connection with any distribution, and (b) each notice of the exercise of any
portion of this Option shall be accompanied by a representation and warranty in
writing, signed by the person entitled to exercise the same, that the shares are
being so acquired in good faith for his or her personal account, not with a view
to or for sale in connection with any distribution, and that such person will
not sell or otherwise transfer the shares without delivering to the Company such
documentation requested by the Company, in its sole and absolute discretion
including, but not limited to an opinion of counsel acceptable to the Company,
that shall reasonably satisfy the Company that such transaction will comply with
the registration and requirements of the Act and the registration or
qualification requirements of applicable state securities laws. Grantee agrees
that any certificate for shares of stock issued upon Exercise of this Option may
bear a legend indicating the restriction on transfer set forth herein.

                  No certificate or certificates for shares of stock purchased
upon exercise of this Option shall be issued and delivered unless and until, in
the opinion of legal counsel for the Company, such securities may be issued and
delivered without causing the Company to be in violation of or incur any
liability under any federal, state or other securities law or any other
requirement of law or of any regulatory body having jurisdiction over the
Company.

         9. LOCK-UP AGREEMENT. In the event that the Company contemplates a
secondary or follow-on public offering of its shares and the underwriter
requests that shareholders or option holders including the holder of this Option
or shares issued or issuable in connection with this Option to sign a lock-up
agreement containing restrictions on the sale of such shares, the Grantee agrees
to execute such lock-up agreement on the same terms as other shareholders. The

                                        3

<PAGE>

Grantee agrees and consents to the entry of stock transfer instructions with the
Company's transfer agent and registrar and a legend placed on certificates for
the shares issued by the Company pursuant to this Option which prohibit the
transfer of the securities held by the Grantee except in compliance with the
terms of this Section 9. For purposes of this Section 9 the term "Grantee"
includes entities to whom Grantee has transferred this Option or the shares
issuable pursuant to the Exercise of this Option.

         10. NOTICES. Any notice to be given to the Company shall be addressed
to the Company in care of its Secretary at its principal office, and any notice
to be given to the Grantee shall be addressed to the Grantee at the address set
forth beneath the Grantee's signature hereto or at such other address as the
Grantee may hereafter designate in writing to the Company. Any such notice shall
be deemed duly given when enclosed in a properly sealed envelope or wrapper
addressed as aforesaid, registered or certified, and deposited, postage and
registry or certification fees prepaid, in a post office or branch post office
regularly maintained by the United States Postal Service.

         11. RULES OF CONSTRUCTION. This Agreement has been executed and
delivered by the Company in California and shall be construed and enforced in
accordance with the laws of this State, other than any choice of law rules
calling for the application of laws of another jurisdiction

         IN WITNESS WHEREOF, the Company has granted this Option on the date of
grant specified above.

     Holders may be embodied in and evidenced by one or more instruments of
     substantially similar tenor signed by such Holders in person or by an agent
     of such Holders duly appointed in writing; and, except as herein otherwise
     expressly provided, such action shall become effective when such instrument
     or instruments are delivered to the Agent and, where it is hereby expressly
     required, to the Company. Such instrument or instruments (and the action
     embodied therein and evidenced thereby) are herein sometimes referred to as
     the "Act" of the Holders signing such instrument or instruments. Proof of
     execution of any such instrument or of a writing appointing any such agent

                                       14

<PAGE>

     (subject to Section 7.1) conclusive in favor of the Agent and the Company,
     if made in the manner provided in this Section.

     sufficient.

     the Equity Units Register or the Stripped Units Register, as the case may
     be.

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

          (e) The Company may set any day as a record date for the purpose of
     determining the Holders of Outstanding Units entitled to give, make or take
     any request, demand, authorization, direction, notice, consent, waiver or
     other action provided or permitted by this Agreement to be given, made or
     taken by Holders of Equity Units and Stripped Units. If any record date is
     set pursuant to this paragraph, the Holders of the Outstanding Units on
     such record date, and no other Holders, shall be entitled to take the
     relevant action with respect to the Equity Units or the Stripped Units, as
     the case may be, whether or not such Holders remain Holders after such
     record date; provided that no such action shall be effective hereunder
     unless taken on or prior to the applicable Expiration Date by Holders of
     the requisite number of Outstanding Units on such record date. Nothing in
     this paragraph shall be construed to prevent the Company from setting a new
     record date for any action for which a record date has previously been set
     pursuant to this paragraph (whereupon the record date previously set shall
     automatically and with no action by any Person be cancelled and of no
     effect), and nothing in this paragraph shall be construed to render
     ineffective any action taken by Holders of the requisite number of
     Outstanding Units on the date such action is taken. Promptly after any
     record date is set pursuant to this paragraph, the Company, at its own
     expense, shall cause notice of such record date, the proposed action by
     Holders and the applicable Expiration Date to be given to the Agent in
     writing and to each Holder of Equity Units and Stripped Units in the manner
     set forth in Section 1.6.

          (f) With respect to any record date set pursuant to this Section, the
     Company may designate any date as the "Expiration Date" and from time to
     time may change the Expiration Date to any earlier or later day; provided
     that no such change shall be effective unless notice of the proposed new
     Expiration Date is given to the Agent in writing, and to each Holder of
     Equity Units and Stripped Units in the manner set forth in Section 1.6, on
     or prior to the existing Expiration Date. If an Expiration Date is not
     designated with respect to any record date set pursuant to this Section,
     the Company shall be deemed to have initially designated the 180th day
     after such record date as the Expiration Date with respect thereto, subject
     to its right to change the Expiration Date as provided in this paragraph.

                                       15

<PAGE>

          Notwithstanding the foregoing, no Expiration Date shall be later than
          the 180th day after the applicable record date.

<PAGE>

          earliest date, prescribed for the giving of such notice. In any case
          where notice to Holders is given by mail, neither the failure to mail
          such notice nor any defect in any notice so mailed to any particular
          Holder shall affect the sufficiency of such notice with respect to
          other Holders. Where this Agreement provides for notice in any manner,
          such notice may be waived in writing by the Person entitled to receive
          such notice, either before or after the event, and such waiver shall
          be the equivalent of such notice. Waivers of notice by Holders shall
          be filed with the Agent, but such filing shall not be a condition
          precedent to the validity of any action taken in reliance upon such
          waiver.

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

               (a) In any case where any Payment Date shall not be a Business
          Day, then (notwithstanding any other provision of this Agreement or
          the Equity Units Certificates) payments on the Notes shall not be made
          on such date, but such payments shall be made on the next succeeding
          Business Day with the same force and effect as if made on such Payment
          Date, provided that no interest shall accrue or be payable by the
          Company for the period from and after any such Payment Date, except
          that if such next succeeding Business Day is in the next succeeding
          calendar year, such payment shall be made on the Business Day
          immediately preceding the Payment Date with the same force and effect
          as if made on such Payment Date.

               (b) If any date on which Contract Adjustment Payments are to be
          made on the Forward Purchase Contracts is not a Business Day, then
          payment of the Contract Adjustment Payments payable on that date will
          be made on the next succeeding day which is a Business Day, and no
          interest or additional payment will be paid in respect of the delay.
          However, if that Business Day is in the next succeeding calendar year,
          the payment will be made on the Business Day immediately preceding the

          not be performed on such date, but the Forward Purchase Contracts
          shall be performed on the immediately following Business Day with the
          same force and effect as if performed on the Stock Purchase Date.

                                THE EQUITY UNITS

          Section 3.1     Title and Terms; Denominations.

               (a) The aggregate number of Equity Units and Stripped Units, if
          any, evidenced by Certificates authenticated, executed on behalf of
          the Holders and delivered hereunder is limited to 6,000,000 (6,900,000
          if the Underwriters' (as defined in the Underwriting Agreement)
          over-allotment option pursuant to the Underwriting Agreement is
          exercised in full), except for Certificates authenticated, executed
          and delivered upon registration of transfer of, in exchange for, or in
          lieu of other Certificates pursuant to Section 3.4, 3.5, 3.10, 3.13,
          3.14, 5.9, 5.10 or 8.5.

               (b) The Certificates shall be issuable only in registered form
          and only in denominations of a single Equity Unit and any integral
          multiple thereof.

          Section 3.2     Rights and Obligations Evidenced by the Certificates.

               (a) Each Equity Units Certificate shall evidence the number of
          Equity Units specified therein, with each such Equity Units
          Certificate representing the ownership by the Holder thereof of a
          beneficial interest in a Note or the appropriate Treasury
          Consideration or Applicable Ownership Interest in the Treasury
          Portfolio, as the case may be, subject to the Pledge of such Note or
          such Treasury Consideration or Applicable Ownership Interest in the
          Treasury Portfolio, as the case may be, by such Holder pursuant to the
          Pledge Agreement, and the rights and obligations of the Holder thereof
          and the Company under one Forward Purchase Contract. The Agent as
          attorney-in-fact for, and on behalf of, the Holder of each Equity Unit
          shall pledge, pursuant to the Pledge Agreement, the Note or the
          appropriate Treasury Consideration or Applicable Ownership Interest in
          the Treasury Portfolio, as the case may be, forming a part of such
          Equity Units, to the Collateral Agent and grant to the Collateral
          Agent a security interest in the right, title, and interest of such
          Holder in such Note or such Treasury Consideration or Applicable
          Ownership Interest in the Treasury Portfolio, as the case may be, for
          the benefit of the Company, to secure the obligation of the Holder
          under each Forward Purchase Contract to purchase the Common Stock of
          the Company. Prior to the purchase of shares of Common Stock under
          each Forward Purchase Contract, such Forward Purchase Contracts shall
          not entitle the Holders of Equity Units Certificates to any of the
          rights of a holder of shares of Common Stock, including, without
          limitation, the right to vote or receive any dividends or other
          payments or to consent or to receive notice as stockholders in respect
          of the meetings of stockholders or for the election of directors of
          the Company or for any other matter, or any other rights whatsoever as
          stockholders of the Company.

               (b) Each Stripped Units Certificate shall evidence the number of
          Stripped Units specified therein, with each such Stripped Units
          Certificate representing the ownership by the Holder thereof of a 1/20
          undivided beneficial interest in a Treasury Security, subject to the
          Pledge of such interest in such Treasury Security by such Holder
          pursuant to the Pledge Agreement, and the rights and obligations of
          the Holder thereof and the Company under one Forward Purchase
          Contract. The Agent as attorney-in-fact for, and on behalf of, the

                                       20

<PAGE>

          Holder of each Stripped Unit shall pledge, pursuant to the Pledge
          Agreement, the Treasury Security, forming a part of such Stripped
          Unit, to the Collateral Agent and grant to the Collateral Agent a
          security interest in the right, title and interest of such Holder in
          such Treasury Security for the benefit of the Company, to secure the
          obligation of the Holder under each Forward Purchase Contract to
          purchase shares of Common Stock pursuant to this Agreement and the
          related Forward Purchase Contract. Prior to the purchase of shares of
          Common Stock under each Forward Purchase Contract, such Forward
          Purchase Contracts shall not entitle the Holders of Stripped Units
          Certificates to any of the rights of a holder of shares of Common
          Stock, including, without limitation, the right to vote or receive any
          dividends or other payments or to consent or to receive notice as
          stockholders in respect of the meetings of stockholders or for the
          election of directors of the Company or for any other matter, or any
          other rights whatsoever as stockholders of the Company.

          Section 3.3     Execution, Authentication, Delivery and Dating.

               (a) Subject to the provisions of Sections 3.13 and 3.14, upon the
          execution and delivery of this Agreement, and at any time and from
          time to time thereafter, the Company may deliver Certificates executed
          by the Company to the Agent for authentication, execution on behalf of
          the Holders and delivery, together with its Issuer Order for
          authentication of such Certificates, and the Agent in accordance with
          such Issuer Order shall authenticate, execute on behalf of the Holders
          and deliver such Certificates.

               (b) The Certificates shall be executed on behalf of the Company
          by the Chief Executive Officer, the Chief Financial Officer, the
          President, any Vice-President, the Treasurer, any Assistant Treasurer,
          the Secretary or any Assistant Secretary (or other officer performing
          similar functions) of the Company and delivered to the Agent. The
          signature of any of these officers on the Certificates may be manual
          or by facsimile.

               (c) Certificates bearing the manual or facsimile signatures of
          individuals who were at any time the proper officers of the Company
          shall bind the Company, notwithstanding that such individuals or any
          of them have ceased to hold such offices prior to the authentication
          and delivery of such Certificates or did not hold such offices at the
          date of such Certificates.

               (d) No Forward Purchase Contract evidenced by a Certificate shall
          be valid until such Certificate has been executed on behalf of the
          Holder by the manual signature of an authorized signatory of the
          Agent, as such Holder's attorney-in-fact. Such signature by an
          authorized signatory of the Agent shall be conclusive evidence that
          the Holder of such Certificate has entered into the Forward Purchase
          Contracts evidenced by such Certificate.

               (e) Each Certificate shall be dated the date of its
          authentication.

               (f) No Certificate shall be entitled to any benefit under this
          Agreement or be valid or obligatory for any purpose unless there
          appears on such Certificate a certificate of authentication
          substantially in the form provided for herein executed by an
          authorized signatory of the Agent by manual signature, and such
          certificate upon any Certificate shall

                                       21

<PAGE>

          be conclusive evidence, and the only evidence, that such Certificate
          has been duly authenticated and delivered hereunder.

          Section 3.4     Temporary Certificates.

               (a) Pending the preparation of definitive Certificates, the
          Company shall execute and deliver to the Agent, and the Agent shall
          authenticate, execute on behalf of the Holders, and deliver, in lieu
          of such definitive Certificates, temporary Certificates which are in
          substantially the form set forth in Exhibit A or Exhibit B hereto, as
          the case may be, with such letters, numbers or other marks of
          identification or designation and such legends or endorsements
          printed, lithographed or engraved thereon as may be required by the
          rules of any securities exchange on which the Equity Units or Stripped
          Units, as the case may be, are listed, or as may, consistent herewith,
          be determined by the officers of the Company executing such
          Certificates, as evidenced by their execution of the Certificates.

               (b) If temporary Certificates are issued, the Company will cause
          definitive Certificates to be prepared without unreasonable delay.
          After the preparation of definitive Certificates, the temporary
          Certificates shall be exchangeable for definitive Certificates upon
          surrender of the temporary Certificates at the Corporate Trust Office,
          at the expense of the Company and without charge to the Holder. Upon
          surrender for cancellation of any one or more temporary Certificates,
          the Company shall execute and deliver to the Agent, and the Agent
          shall authenticate, execute on behalf of the Holder, and deliver in
          exchange therefor, one or more definitive Certificates of like tenor
          and denominations and evidencing a like number of Equity Units or
          Stripped Units, as the case may be, as the temporary Certificate or
          Certificates so surrendered. Until so exchanged, the temporary
          Certificates shall in all respects evidence the same benefits and the
          same obligations with respect to the Equity Units or Stripped Units,
          as the case may be, evidenced thereby as definitive Certificates.

          Section 3.5     Registration; Registration of Transfer and Exchange.

               (a) The Agent shall keep at the Corporate Trust Office a register
          (the "Equity Units Register") in which, subject to such reasonable
          regulations as it may prescribe, the Agent shall provide for the
          registration of Equity Units Certificates and of transfers of Equity
          Units Certificates (the Agent, in such capacity, the "Equity Units
          Registrar") and a register (the "Equity Units Register") in which,
          subject to such reasonable regulations as it may prescribe, the Agent
          shall provide for the registration of the Equity Units Certificates
          and transfers of Equity Units Certificates (the Agent, in such
          capacity, the "Equity Units Registrar").

               (b) Upon surrender for registration of transfer of any
          Certificate at the Corporate Trust Office, the Company shall execute
          and deliver to the Agent, and the Agent shall authenticate, execute on
          behalf of the designated transferee or transferees, and deliver, in
          the name of the designated transferee or transferees, one or more new
          Certificates of like tenor and denominations, and evidencing a like
          number of Equity Units or Stripped Units, as the case may be.

                                       22

<PAGE>

               (c) At the option of the Holder, Certificates may be exchanged
          for other Certificates, of like tenor and denominations and evidencing
          a like number of Equity Units or Stripped Units, as the case may be,
          upon surrender of the Certificates to be exchanged at the Corporate
          Trust Office. Whenever any Certificates are so surrendered for
          exchange, the Company shall execute and deliver to the Agent, and the
          Agent shall authenticate, execute on behalf of the Holder, and deliver
          the Certificates which the Holder making the exchange is entitled to
          receive.

               (d) All Certificates issued upon any registration of transfer or
          exchange of a Certificate shall evidence the ownership of the same
          number of Equity Units or Stripped Units, as the case may be, and be
          entitled to the same benefits and subject to the same obligations,
          under this Agreement as the Equity Units or Stripped Units, as the
          case may be, evidenced by the Certificate surrendered upon such
          registration of transfer or exchange.

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

               (f) No service charge shall be made for any registration of
          transfer or exchange of a Certificate, but the Company and the Agent
          may require payment from the Holder of a sum sufficient to cover any
          tax or other governmental charge that may be imposed in connection
          with any registration of transfer or exchange of Certificates, other
          than any exchanges pursuant to Sections 3.4, 3.6, 3.9 and 8.5 not
          involving any transfer.

               (g) Notwithstanding the foregoing, the Company shall not be
          obligated to execute and deliver to the Agent, and the Agent shall not
          be obligated to authenticate, execute on behalf of the Holder and
          deliver any Certificate presented or surrendered for registration of
          transfer or for exchange on or after the Business Day immediately
          preceding the earlier of the Stock Purchase Date or the Termination
          Date. In lieu of delivery of a new Certificate, upon satisfaction of
          the applicable conditions specified above in this Section and receipt
          of appropriate registration or transfer instructions from such Holder,
          the Agent shall,

                    (i)   if the Stock Purchase Date has occurred, deliver the
               shares of Common Stock issuable in respect of the Forward
               Purchase Contracts forming a part of the Equity Units or Stripped
               Units, as the case may be, evidenced by such Certificate,

                    (ii)  in the case of Equity Units, if a Termination Event
               shall have occurred prior to the Stock Purchase Date, transfer
               the Notes or the appropriate Treasury Consideration or Applicable
               Ownership Interest in the Treasury Portfolio, as applicable,
               relating to such Equity Units, or

                    (iii) in the case of Stripped Units, if a Termination Event
               shall have occurred prior to the Stock Purchase Date, transfer
               the Treasury Securities relating to such Stripped Units,

                                       23

<PAGE>

in each case subject to the applicable conditions and in accordance with the
applicable provisions of Article V.

          Section 3.6    Book-Entry Interests.

          The Certificates, on original issuance will be issued in the form of
one or more fully registered Global Certificates, to be delivered to the
Depositary or its custodian by, or on behalf of, the Company. Such Global
Certificate shall initially be registered in the applicable Register in the name
of Cede & Co., the nominee of the Depositary, and no Beneficial Owner will
receive a definitive Certificate representing such Beneficial Owner's interest
in such Global Certificate, except as provided in Section 3.9. The Agent shall
enter into an agreement with the Depositary if so requested by the Company.
Unless and until definitive, fully registered Certificates have been issued to
Beneficial Owners pursuant to Section 3.9:

               (a) the provisions of this Section 3.6 shall be in full force and
          effect;

               (b) the Company shall be entitled to deal with the Clearing
          Agency for all purposes of this Agreement (including receiving
          approvals, votes or consents hereunder) as the Holder of the Equity
          Units and Stripped Units and the sole holder of the Global
          Certificate(s) and shall have no obligation to the Beneficial Owners;

               (c) to the extent that the provisions of this Section 3.6
          conflict with any other provisions of this Agreement, the provisions
          of this Section 3.6 shall control; and

               (d) the rights of the Beneficial Owners shall be exercised only
          through the Clearing Agency and shall be limited to those established
          by law and agreements between such Beneficial Owners and the Clearing
          Agency and/or the Clearing Agency Participants. The Clearing Agency
          will make book-entry transfers among Clearing Agency Participants.

          Section 3.7    Notices To Holders.

          Whenever a notice or other communication to the Holders is required to
be given under this Agreement, the Company or the Company's agent shall give
such notices and communications to the Holders and, with respect to any Equity
Units or Stripped Units registered in the name of a Clearing Agency or the
nominee of a Clearing Agency, the Company or the Company's agent shall, except
as set forth herein, have no obligations to the Beneficial Owners.

          Section 3.8    Appointment of Successor Clearing Agency.

          If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Equity Units and Stripped Units or
ceases to be eligible as a "clearing agency" under the Exchange Act, the Company
may, in its sole discretion, appoint a successor Clearing Agency with respect to
the Equity Units and Stripped Units.

          Section 3.9    Definitive Certificates.

          If

                                       24

<PAGE>

                    (i)   a Clearing Agency elects to discontinue its services
               as securities depositary with respect to the Equity Units and
               Stripped Units or ceases to be eligible as a "clearing agency"
               under the Exchange Act and a successor Clearing Agency is not
               appointed within 90 days after such discontinuance pursuant to
               Section 3.8,

                    (ii)  the Company elects to terminate the book-entry system
               through the Clearing Agency with respect to the Equity Units and
               Stripped Units, or

                    (iii) there shall have occurred and be continuing a default
               by the Company in respect of its obligations under one or more
               Forward Purchase Contracts, this Agreement, the Indenture, the
               Notes, the Equity Units, the Pledge Agreement or any other
               principal agreements or instruments executed in connection with
               the offering of Equity Units

then upon surrender of the Global Certificates representing the Book-Entry
Interests with respect to the Equity Units and Stripped Units by the Clearing
Agency, accompanied by registration instructions, the Company shall cause
definitive Certificates to be delivered to Clearing Agency Participants in
accordance with the instructions of the Clearing Agency. The Company and the
Agent shall not be liable for any delay in delivery of such instructions and may
conclusively rely on and shall be protected in relying on such instructions.

          Section 3.10   Mutilated, Destroyed, Lost and Stolen Certificates.

               (a) If any mutilated Certificate is surrendered to the Agent, the
          Company shall execute and deliver to the Agent, and the Agent shall
          authenticate, execute on behalf of the Holder, and deliver in exchange
          therefor, a new Certificate at the cost of the Holder, evidencing the
          same number of Equity Units or Stripped Units, as the case may be, and
          bearing a Certificate number not contemporaneously outstanding.

               (b) If there shall be delivered to the Company and the Agent (i)
          evidence to their satisfaction of the destruction, loss or theft of
          any Certificate, and (ii) such security or indemnity at the cost of
          the Holder as may be required by them to hold each of them and any
          agent of any of them harmless, then, in the absence of notice to the
          Company or the Agent that such Certificate has been acquired by a bona
          fide purchaser, the Company shall execute and deliver to the Agent,
          and the Agent shall authenticate, execute on behalf of the Holder, and
          deliver to the Holder, in lieu of any such destroyed, lost or stolen
          Certificate, a new Certificate, evidencing the same number of Equity
          Units or Stripped Units, as the case may be, and bearing a Certificate
          number not contemporaneously outstanding.

               (c) Notwithstanding the foregoing, the Company shall not be
          obligated to execute and deliver to the Agent, and the Agent shall not
          be obligated to authenticate, execute on behalf of the Holder, and
          deliver to the Holder, a Certificate on or after the Business Day
          immediately preceding the earlier of the Stock Purchase Date or the
          Termination Date. In lieu of delivery of a new Certificate, upon
          satisfaction of the applicable conditions specified above in this
          Section and receipt of appropriate registration or transfer
          instructions from such Holder, the Agent shall (i) if the Stock
          Purchase Date has occurred,

                                       25

<PAGE>

          deliver the shares of Common Stock issuable in respect of the Forward
          Purchase Contracts forming a part of the Equity Units or Stripped
          Units evidenced by such Certificate, or (ii) if a Termination Event
          shall have occurred prior to the Stock Purchase Date, transfer the
          Notes, the appropriate Treasury Consideration or Applicable Ownership
          Interest in the Treasury Portfolio, or the Treasury Securities, as the
          case may be, evidenced thereby, in each case subject to the applicable
          conditions and in accordance with the applicable provisions of Article
          V.

               (d) Upon the issuance of any new Certificate under this Section,
          the Company and the Agent may require the payment by the Holder 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 Agent) connected therewith.

               (e) Every new Certificate issued pursuant to this Section in lieu
          of any destroyed, lost or stolen Certificate shall constitute an
          original contractual obligation of the Company and of the Holder in
          respect of the Equity Units or Stripped Units, as the case may be,
          evidenced thereby, whether or not the destroyed, lost or stolen
          Certificate (and the Equity Units and Stripped Units evidenced
          thereby) shall be at any time enforceable by anyone, and shall be
          entitled to all the benefits and be subject to all the obligations of
          this Agreement equally and proportionately with any and all other
          Certificates delivered hereunder.

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

          Section 3.11 Persons Deemed Owners.

               (a) Prior to due presentment of a Certificate for registration of
          transfer, the Company and the Agent, and any agent of the Company or
          the Agent, may treat the Person in whose name such Certificate is
          registered as the owner of the Equity Units or Stripped Units, as the
          case may be, evidenced thereby, for the purpose of receiving interest
          payments on the Notes, receiving payment of Contract Adjustment
          Payments, performance of the Forward Purchase Contracts and for all
          other purposes whatsoever (subject to Section 4.1(a) and 5.2(a)),
          whether or not any such payments shall be overdue and notwithstanding
          any notice to the contrary, and neither the Company nor the Agent, nor
          any agent of the Company or the Agent, shall be affected by notice to
          the contrary.

               (b) Notwithstanding the foregoing, with respect to any Global
          Certificate, nothing herein shall prevent the Company, the Agent or
          any agent of the Company or the Agent from giving effect to any
          written certification, proxy or other authorization furnished by any
          Clearing Agency (or its nominee), as a Holder, with respect to such
          Global Certificate or impair, as between such Clearing Agency and
          owners of beneficial interests in such Global Certificate, the
          operation of customary practices governing the exercise of rights of
          such Clearing Agency (or its nominee) as Holder of such Global
          Certificate. None of the Company, the Agent, or any agent of the
          Company or the Agent will have any responsibility or liability for any
          aspect of the records relating to or payments made on

                                       26

<PAGE>

          account of beneficial ownership interests in a Global Certificate or
          maintaining, supervising or reviewing any records relating to such
          beneficial ownership interests.

          Section 3.12   Cancellation.

               (a) All Certificates surrendered (i) for delivery of shares of
          Common Stock on or after any Settlement Date; (ii) upon the transfer
          of Notes, the appropriate Treasury Consideration or Applicable
          Ownership Interest in the Treasury Portfolio, or Treasury Securities,
          as the case may be, after the occurrence of a Termination Event; or
          (iii) upon the registration of a transfer or exchange of Equity Units
          or Stripped Units, as the case may be, shall, if surrendered to any
          Person other than the Agent, be delivered to the Agent and, if not
          already cancelled, shall be promptly cancelled by it. The Company may
          at any time deliver to the Agent for cancellation any Certificates
          previously authenticated, executed and delivered hereunder which the
          Company may have acquired in any manner whatsoever, and all
          Certificates so delivered shall, upon Issuer Order, be promptly
          cancelled by the Agent. No Certificates shall be authenticated,
          executed on behalf of the Holder and delivered in lieu of or in
          exchange for any Certificates cancelled as provided in this Section,
          except as expressly permitted by this Agreement. All cancelled
          Certificates held by the Agent shall be disposed of by the Agent in
          accordance with its customary procedures.

               (b) If the Company or any Affiliate of the Company shall acquire
          any Certificate, such acquisition shall not operate as a cancellation
          of such Certificate unless and until such Certificate is cancelled or
          delivered to the Agent for cancellation.

          Section 3.13   Establishment of Stripped Units.

               (a) Unless a successful remarketing or a Tax Event Redemption has
          occurred, a Holder may separate the Pledged Notes from the related
          Forward Purchase Contracts in respect of the Equity Units held by such
          Holder by substituting for such Pledged Notes Treasury Securities that
          will pay, on the Stock Purchase Date, an amount equal to the aggregate
          principal amount of such Notes (a "Collateral Substitution"), at any
          time from and after the date of this Agreement and on or prior to the
          tenth Business Day immediately preceding the Stock Purchase Date, by
          (i) depositing with the Collateral Agent Treasury Securities having an
          aggregate principal amount equal to the aggregate Stated Amount of
          such Equity Units, and (ii) transferring the related Equity Units to
          the Agent accompanied by a notice to the Agent, substantially in the
          form of Exhibit D hereto, stating that the Holder has transferred the
          relevant amount of Treasury Securities to the Collateral Agent and
          requesting that the Agent instruct the Collateral Agent to release the
          Pledged Notes underlying such Equity Units, whereupon the Agent shall
          promptly give such instruction to the Collateral Agent, substantially
          in the form of Exhibit C hereto. Notwithstanding the foregoing, a
          Holder may not separate the Pledged Notes from the related Forward
          Purchase Contracts in respect of the Equity Units held by such Holder
          during the periods beginning on the fourth Business Day prior to any
          Remarketing Period and ending on the third Business Day after the end
          of such Remarketing Period. Upon receipt of the Treasury Securities
          described in clause (i) above and the instruction described in clause
          (ii) above, in accordance with the terms of the Pledge Agreement, the
          Collateral Agent will release to the

                                       27

<PAGE>

     Agent, on behalf of the Holder, such Pledged Notes from the Pledge, free
     and clear of the Company's security interest therein, and upon receipt
     thereof the Agent shall promptly:

               (i)   cancel the related Equity Units;

               (ii)  transfer the Pledged Notes to the Holder; and

               (iii) authenticate, execute on behalf of such Holder and deliver
          to such Holder a Stripped Units Certificate executed by the Company in
          accordance with Section 3.3 evidencing the same number of Forward
          Purchase Contracts as were evidenced by the cancelled Equity Units.

          (b) Holders who elect to separate the Pledged Notes from the related
     Forward Purchase Contract and to substitute Treasury Securities for such
     Pledged Notes shall be responsible for any fees or expenses payable to the
     Collateral Agent for its services as Collateral Agent in respect of the
     substitution, and the Company shall not be responsible for any such fees or
     expenses.

          (c) Holders may make Collateral Substitutions if Treasury Securities
     are being substituted for Pledged Notes, only in integral multiples of 20
     Equity Units.

          (d) In the event a Holder making a Collateral Substitution pursuant to
     this Section 3.13 fails to effect a book-entry transfer of the Equity Units
     or fails to deliver an Equity Units Certificate to the Agent after
     depositing Treasury Securities with the Collateral Agent, the Pledged Notes
     constituting a part of such Equity Units, and any distributions on such
     Pledged Notes shall be held in the name of the Agent or its nominee in
     trust for the benefit of such Holder, until such Equity Units are so
     transferred or the Equity Units Certificate is so delivered, as the case
     may be, or, with respect to an Equity Units Certificate, such Holder
     provides evidence satisfactory to the Company and the Agent that such
     Equity Units Certificate has been destroyed, lost or stolen, together with
     any indemnity that may be required by the Agent and the Company.

          (e) Except as described in this Section 3.13, for so long as the
     Forward Purchase Contract underlying an Equity Unit remains in effect, such
     Equity Unit shall not be separable into its constituent parts, and the
     rights and obligations of the Holder of such Equity Unit in respect of the
     Note or the appropriate Treasury Consideration or Applicable Ownership
     Interest in the Treasury Portfolio, as the case may be, and the Forward
     Purchase Contract comprising such Equity Unit may be acquired, and may be
     transferred and exchanged, only as an Equity Unit.

     Section 3.14     Reestablishment of Equity Units.

          (a) Unless a successful remarketing or a Tax Event Redemption has
     occurred, a Holder of Stripped Units may reestablish Equity Units at any
     time from and after the date of this Agreement and on or prior to the tenth
     Business Day immediately preceding the Stock Purchase Date, by (i)
     depositing with the Collateral Agent the Notes then comprising such number
     of Equity Units as is equal to such Stripped Units and (ii) transferring
     such Stripped Units to the Agent accompanied by a notice to the Agent,
     substantially in the form

                                       28

<PAGE>

     of Exhibit D hereto, stating that the Holder has transferred the relevant
     amount of Notes to the Collateral Agent and requesting that the Agent
     instruct the Collateral Agent to release the Pledged Treasury Securities
     underlying such Stripped Units, whereupon the Agent shall promptly give
     such instruction to the Collateral Agent, substantially in the form of
     Exhibit C hereto. Notwithstanding the foregoing, a Holder may not
     reestablish Equity Units during the periods beginning on the fourth
     Business Day prior to any Remarketing Period and ending on the third
     Business Day after the end of such Remarketing Period. Upon receipt of the
     Notes described in clause (i) above and the instruction described in clause
     (ii) above, in accordance with the terms of the Pledge Agreement, the
     Collateral Agent will release to the Agent, on behalf of the Holder, such
     Pledged Treasury Securities from the Pledge, free and clear of the
     Company's security interest therein, and upon receipt thereof the Agent
     shall promptly:

               (i)   cancel the related Stripped Units;

               (ii)  transfer the Pledged Treasury Securities to the Holder; and

               (iii) authenticate, execute on behalf of such Holder and deliver
          an Equity Units Certificate executed by the Company in accordance with
          Section 3.3 evidencing the same number of Forward Purchase Contracts
          as were evidenced by the cancelled Stripped Units.

          (b) Holders of Stripped Units may reestablish Equity Units only in
     integral multiples of 20 Stripped Units for 20 Equity Units.

          (c) Except as provided in this Section 3.14, for so long as the
     Forward Purchase Contract underlying a Stripped Unit remains in effect,
     such Stripped Unit shall not be separable into its constituent parts, and
     the rights and obligations of the Holder of such Stripped Unit in respect
     of the Treasury Security and Forward Purchase Contract comprising such
     Stripped Unit may be acquired, and may be transferred and exchanged, only
     as a Stripped Unit.

          (d) Holders of Stripped Units who reestablish Equity Units shall be
     responsible for any fees or expenses payable to the Collateral Agent for
     its services as Collateral Agent in respect of the substitution, and the
     Company shall not be responsible for any such fees or expenses.

          (e) In the event a Holder who reestablishes Equity Units pursuant to
     this Section 3.14 fails to effect a book-entry transfer of the Stripped
     Units or fails to deliver a Stripped Units Certificate to the Agent after
     depositing Pledged Notes with the Collateral Agent, the Treasury Securities
     constituting a part of such Stripped Units, and any distributions on such
     Treasury Securities shall be held in the name of the Agent or its nominee
     in trust for the benefit of such Holder, until such Stripped Units are so
     transferred or the Stripped Units Certificate is so delivered, as the case
     may be, or, with respect to a Stripped Units Certificate, such Holder
     provides evidence satisfactory to the Company and the Agent that such
     Stripped Units Certificate has been destroyed, lost or stolen, together
     with any indemnity that may be required by the Agent and the Company.

     Section 3.15   Transfer of Collateral Upon Occurrence of Termination Event.

     Upon the occurrence of a Termination Event and the transfer to the Agent by
the Collateral Agent of the Notes, the appropriate Treasury Consideration or
Applicable Ownership Interest in the Treasury Portfolio, or the Treasury
Securities, as the case may be, underlying the Equity Units or the Stripped
Units, as the case may be, pursuant to the terms of the Pledge Agreement, the
Agent shall request transfer instructions with respect to such Notes or the
appropriate Treasury Consideration or Applicable Ownership Interest in the
Treasury Portfolio, or Treasury Securities, as the case may be, from each Holder
by written request mailed to such Holder at its address as it appears in the
Equity Units Register or the Stripped Units Register, as the case may be. Upon
book-entry transfer of the Equity Units or Stripped Units or delivery of an
Equity Units Certificate or Stripped Units Certificate to the Agent with such
transfer instructions, the Agent shall transfer the Notes, the appropriate
Treasury Consideration or Applicable Ownership Interest in the Treasury
Portfolio, or Treasury Securities, as the case may be, underlying such Equity
Units or Stripped Units, as the case may be, to such Holder by book-entry
transfer, or other appropriate procedures, in accordance with such instructions.
In the event a Holder would be entitled to receive less than $1,000 principal
amount at maturity of any Treasury security, the Agent shall dispose of such
Treasury security for cash and deliver such cash to the Holder. In the event a
Holder of Equity Units or Stripped Units fails to effect such transfer or
delivery, the Notes, the appropriate Treasury Consideration or Applicable
Ownership Interest in the Treasury Portfolio or Treasury Securities, as the case
may be, underlying such Equity Units or Stripped Units, as the case may be, and
any distributions thereon, shall be held in the name of the Agent or its nominee
in trust for the benefit of such Holder, until (i) such Equity Units or Stripped
Units are transferred or the Equity Units Certificate or Stripped Units
Certificate is surrendered or such Holder provides satisfactory evidence that
such Equity Units Certificate or Stripped Units Certificate has been destroyed,
lost or stolen, together with any indemnity that may be required by the Agent
and the Company; and (ii) the expiration of the time period specified in the
abandoned property laws of the relevant State.

     Section 3.16   No Consent to Assumption.

     Each Holder of Equity Units or Stripped Units, as the case may be, by
acceptance thereof, shall be deemed expressly to have withheld any consent to
the assumption under Section 365 of the Bankruptcy Code or otherwise, of the
Forward Purchase Contract by the Company, any receiver, liquidator or person or
entity performing similar functions or its trustee in the event that the Company
becomes the debtor under the Bankruptcy Code or subject to other similar state
or federal law providing for reorganization or liquidation.

     Section 4.1    Payment of Interest; Rights to Interest Payments Preserved;
                    Notice.

          (a) A payment on any Note, Treasury Consideration or Applicable
     Ownership Interest in the Treasury Portfolio, as the case may be, which is
     paid on any Payment Date other than a Payment Date with respect to the
     Stated Amount due on Treasury Consideration or Applicable Ownership
     Interest in the Treasury Portfolio shall, subject to receipt thereof by the
     Agent from the Collateral Agent (if the Collateral Agent is the

                                       30

<PAGE>

     registered owner thereof) as provided by the terms of the Pledge Agreement,
     be paid to the Person in whose name the Equity Units Certificate (or one or
     more Predecessor Equity Units Certificates) of which such Note or the
     appropriate Treasury Consideration or Applicable Ownership Interest in the
     Treasury Portfolio, as the case may be, is a part is registered at the
     close of business on the Record Date for such Payment Date.

          (b) Each Equity Units Certificate evidencing Notes delivered under
     this Agreement upon registration of transfer of or in exchange for or in
     lieu of any other Equity Units Certificate shall carry the rights to
     interest accrued and unpaid which were carried by the Notes and Treasury
     Consideration or Applicable Ownership Interest in the Treasury Portfolio,
     as the case may be, underlying such other Equity Units Certificate.

          (c) In the case of any Equity Units with respect to which Early
     Settlement of the underlying Forward Purchase Contract is effected on an
     Early Settlement Date, Merger Early Settlement of the underlying Forward
     Purchase Contract is effected on a Merger Early Settlement Date, Cash
     Settlement is effected on the seventh Business Day immediately preceding
     the Stock Purchase Date, or a Collateral Substitution is effected, in each
     case on a date that is after any Record Date and on or prior to the next
     succeeding Payment Date, payments on the Note or the appropriate Treasury
     Consideration or Applicable Ownership Interest in the Treasury Portfolio,
     as the case may be, underlying such Equity Units otherwise payable on such
     Payment Date shall be payable on such Payment Date notwithstanding such
     Early Settlement, Merger Early Settlement, Cash Settlement or Collateral
     Substitution, as the case may be, and such payments shall, subject to
     receipt thereof by the Agent, be payable to the Person in whose name the
     Equity Units Certificate (or one or more Predecessor Equity Units
     Certificates) was registered at the close of business on the Record Date.
     Except as otherwise expressly provided in the immediately preceding
     sentence, in the case of any Equity Units with respect to which Early
     Settlement, Merger Early Settlement or Cash Settlement of the underlying
     Forward Purchase Contract is effected, or with respect to which a
     Collateral Substitution has been effected, payments on the related Notes or
     payments on the appropriate Treasury Consideration or Applicable Ownership
     Interest in the Treasury Portfolio, as the case may be, that would
     otherwise be payable after the applicable Settlement Date or after such
     Collateral Substitution, as the case may be, shall not be payable hereunder
     to the Holder of such Equity Units; provided, that to the extent that such
     Holder continues to hold the Separate Notes that formerly comprised a part
     of such Holder's Equity Units, such Holder shall be entitled to receive the
     payments on such Separate Notes.

     Section 4.2    Notice and Voting.

     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
Notes but only to the extent instructed by the Holders as described below. Upon
receipt of notice of any meeting at which holders of Notes are entitled to vote
or upon any solicitation of consents, waivers or proxies of holders of Notes,
the Agent shall, as soon as practicable thereafter, mail to the Holders of
Equity Units a notice (a) containing such information as is contained in the
notice or solicitation, (b) stating that each 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 Notes entitled to vote) shall be
entitled to

                                       31

<PAGE>

instruct the Agent as to the exercise of the voting rights pertaining to the
Pledged Notes underlying their Equity Units and (c) stating the manner in which
such instructions may be given. Upon the written request of the Holders of
Equity Units 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 number of Pledged Notes as to which any
particular voting instructions are received. In the absence of specific
instructions from the Holder of an Equity Unit, the Agent shall abstain from
voting the Pledged Note underlying such Equity Units. The Company hereby agrees,
if applicable, to solicit Holders of Equity Units to timely instruct the Agent
in order to enable the Agent to vote such Pledged Notes.

     Section 4.3     Tax Event Redemption.

     Upon the occurrence of a Tax Event Redemption prior to the earlier of a
successful remarketing of the Notes or the Stock Purchase Date, the Company may
elect to instruct in writing the Collateral Agent to apply, and upon such
written instruction, the Collateral Agent shall apply, out of the aggregate
Redemption Price for the Notes that are components of Equity Units, an amount
equal to the aggregate Redemption Amount for the Notes that are components of
Equity Units to purchase on behalf of the Holders of Equity Units the Treasury
Portfolio and promptly remit the remaining portion of such aggregate Redemption
Price to the Agent for payment to the Holders of such Equity Units. The Treasury
Portfolio will be substituted for the Pledged Notes, and will be pledged to the
Collateral Agent in accordance with the terms of the Pledge Agreement to secure
the obligation of each Holder of an Equity Units to purchase the Common Stock
under the Forward Purchase Contract constituting a part of such Equity Units.
Following the occurrence of a Tax Event Redemption prior to the earlier of a
successful remarketing of the Notes or the Stock Purchase Date, the Holders of
Equity Units and the Collateral Agent shall have such security interests, rights
and obligations with respect to the Treasury Portfolio as the Holder of Equity
Units and the Collateral Agent had in respect of the Notes, as the case may be,
subject to the Pledge thereof as provided in Articles II, III, IV, V and VI of
the Pledge Agreement, and any reference herein or in the Certificates to the
Note shall be deemed to be a reference to such Treasury Portfolio and any
reference herein or in the Certificates to interest on the Notes shall be deemed
to be a reference to corresponding distributions on the Treasury Portfolio. The
Company may cause to be made in any Equity Units Certificates thereafter to be
issued such change in phraseology and form (but not in substance) as may be
appropriate to reflect the substitution of the Treasury Portfolio for Notes as
collateral.

     The Company shall cause notice of any Tax Event Redemption to be mailed, at
least 30 calendar days but not more than 60 calendar days before such Tax Event
Redemption Date, to each Holder of Equity Units including Notes to be redeemed
at its registered address.

     Upon the occurrence of a Tax Event Redemption after the earlier of a
successful remarketing of the Notes or the Stock Purchase Date, the Redemption
Price will be payable in cash to the holders of the Notes.

<PAGE>

          (a) Each Forward Purchase Contract shall, unless an Early Settlement
     has occurred in accordance with Section 5.9, or a Merger Early Settlement
     has occurred in accordance with Section 5.10, obligate the Holder of the
     related Equity Units or Stripped Units, as the case may be, to purchase,
     and the Company to sell, on the Stock Purchase Date at a price equal to $50
     (the "Purchase Price"), a number of newly issued shares of Common Stock
     equal to the Settlement Rate unless, on or prior to the Stock Purchase
     Date, there shall have occurred a Termination Event with respect to the
     Units of which such Forward Purchase Contract is a part. The "Settlement
     Rate" is equal to,

               (i)   if the Applicable Market Value (as defined below) is
     greater than or equal to $49.08 (the "Threshold Appreciation Price"),
     1.0187 shares of Common Stock per Forward Purchase Contract,

               (ii)  if the Applicable Market Value is less than the Threshold
     Appreciation Price, but is greater than $40.90, the number of shares of
     Common Stock per Forward Purchase Contract equal to $50 divided by the
     Applicable Market Value, and

               (iii) if the Applicable Market Value is equal to or less than
     $40.90, 1.2225 shares of Common Stock per Forward Purchase Contract,

in each case subject to adjustment as provided in Section 5.6 and in each case
rounded upward or downward to the nearest 1/10,000th of a share.

     As provided in Section 5.12, no fractional shares of Common Stock will be
issued upon settlement of Forward Purchase Contracts.

     Promptly after the calculation of the Settlement Rate and the Applicable
Market Value, the Company shall give the Agent notice thereof. All calculations
and determinations of the Settlement Rate and the Applicable Market Value shall
be made by the Company or its agents based on their good faith calculations, and
the Agent shall have no responsibility with respect thereto.

          (b) The "Applicable Market Value" means the average of the Closing
     Price per share of Common Stock on each of the 20 consecutive Trading Days
     ending on the third Trading Day immediately preceding the Stock Purchase
     Date. The "Closing Price" of the Common Stock on any date of determination
     means the closing sale price (or, if no closing price is reported, the last
     reported sale price) of the Common Stock on the New York Stock Exchange
     (the "NYSE") on such date or, if the Common Stock is not listed for trading
     on the NYSE on any such date, as reported in the composite transactions for
     the principal United States securities exchange on which the Common Stock
     is so listed, or if the Common Stock is not so listed on a United States
     national or regional securities exchange, as reported by The NASDAQ Stock
     Market, or, 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, if such bid
     price is not available, the market value of the Common Stock on such date
     as determined by a nationally recognized independent investment banking
     firm retained for this purpose by the Company. A "Trading Day" means a day
     on which the Common Stock (A) is not

                                       33

<PAGE>

     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.

          (c) Each Holder of Equity Units or Stripped Units, as the case may be,
     by its acceptance thereof, irrevocably authorizes the Agent to enter into
     and perform the related Forward Purchase Contract on its behalf as its
     attorney-in-fact (including the execution of Certificates on behalf of such
     Holder), agrees to be bound by the terms and provisions thereof, covenants
     and agrees to perform its obligations under such Forward Purchase
     Contracts, and consents to the provisions hereof, irrevocably authorizes
     the Agent as its attorney-in-fact to enter into and perform the Pledge
     Agreement on its behalf as its attorney-in-fact, and consents to and agrees
     to be bound by the Pledge of the Notes, the appropriate Treasury
     Consideration or Applicable Ownership Interest in the Treasury Portfolio,
     or the Treasury Securities pursuant to the Pledge Agreement; provided that
     upon a Termination Event, the rights of the Holder of such Equity Units or
     Stripped Units, as the case may be, under the Forward Purchase Contract may
     be enforced without regard to any other rights or obligations. Each Holder
     of Equity Units or Stripped Units, as the case may be, by its acceptance
     thereof, further covenants and agrees that, to the extent and in the manner
     provided in Section 5.4 and the Pledge Agreement, but subject to the terms
     thereof, payments in respect of the Notes, the appropriate Treasury
     Consideration or Applicable Ownership Interest in the Treasury Portfolio,
     or the Treasury Securities, to be paid upon settlement of such Holder's
     obligations to purchase Common Stock under the Forward Purchase Contract,
     shall be paid on the Stock Purchase Date by the Collateral Agent to the
     Company in satisfaction of such Holder's obligations under such Forward
     Purchase Contract and such Holder shall acquire no right, title or interest
     in such payment.

          (d) Upon registration of transfer of a Certificate, the transferee
     shall be bound (without the necessity of any other action on the part of
     such transferee) under the terms of this Agreement, the Forward Purchase
     Contracts underlying such Certificate and the Pledge Agreement, and the
     transferor shall be released from the obligations under this Agreement, the
     Forward Purchase Contracts underlying the Certificates so transferred and
     the Pledge Agreement. The Company covenants and agrees, and each Holder of
     a Certificate, by its acceptance thereof, likewise covenants and agrees, to
     be bound by the provisions of this paragraph.

     Section 5.2    Contract Adjustment Payments.

          (a) Contract Adjustment Payments shall accrue on each Forward Purchase
     Contract constituting a part of an Equity Unit or Stripped Unit at 3.50%
     per year of the Stated Amount of such Equity Unit or Stripped Unit, from
     June 11, 2002 through and including the Stock Purchase Date, provided that
     no Contract Adjustment Payment shall accrue after an Early Settlement or
     Merger Early Settlement. Subject to Section 5.3 herein, the Company shall
     pay, on each Payment Date, the Contract Adjustment Payments, if any,
     payable in respect of each Forward Purchase Contract to the Person in whose
     name a Certificate (or one or more Predecessor Certificates) is registered
     at the close of business on the Record Date immediately preceding such
     Payment Date in such coin or currency of

                                       34

<PAGE>

     the United States as at the time of payment shall be legal tender for
     payments. The Contract Adjustment Payments, if any, will be payable at the
     office in New York, New York, maintained for that purpose or, at the option
     of the Company, by check mailed to the address of the Person entitled
     thereto at such Person's address as it appears on the Register or by wire
     transfer to the account designated to the Agent by a prior written notice
     by such Person delivered at least five Business Days prior to the
     applicable Payment Date.

          (b) Upon the occurrence of a Termination Event, the Company's
     obligation to pay Contract Adjustment Payments (including any accrued
     Deferred Contract Adjustment Payments), if any, shall cease.

          (c) Each Certificate delivered under this Agreement upon registration
     of transfer of or in exchange for or in lieu of (including as a result of a
     Collateral Substitution or the re-establishment of an Equity Unit) any
     other Certificate shall carry the rights to Contract Adjustment Payments,
     if any, accrued and unpaid, and to accrue Contract Adjustment Payments, if
     any, which were carried by the Forward Purchase Contracts underlying such
     other Certificates.

          (d) Subject to Sections 5.9 and 5.10, in the case of any Equity Units
     or Stripped Units, as the case may be, with respect to which Early
     Settlement or Merger Early Settlement of the underlying Forward Purchase
     Contract is effected on an Early Settlement Date or a Merger Early
     Settlement Date, respectively, or in respect of which Cash Settlement of
     the underlying Forward Purchase Contract is effected on the seventh
     Business Day immediately preceding the Stock Purchase Date, or with respect
     to which a Collateral Substitution or an establishment or re-establishment
     of an Equity Units pursuant to Section 3.14 is effected, in each case on a
     date that is after any Record Date and on or prior to the next succeeding
     Payment Date, Contract Adjustment Payments on the Forward Purchase Contract
     underlying such Equity Units or Stripped Units, as the case may be,
     otherwise payable on such Payment Date shall be payable on such Payment
     Date notwithstanding such Cash Settlement, Early Settlement, Merger Early
     Settlement, Collateral Substitution or establishment or re-establishment of
     Equity Units, and such Contract Adjustment Payments shall be paid to the
     Person in whose name the Certificate evidencing such Equity Units or
     Stripped Units (or one or more Predecessor Certificates) is registered at
     the close of business on such Record Date. Except as otherwise expressly
     provided in the immediately preceding sentence, in the case of any Equity
     Units or Stripped Units with respect to which Cash Settlement, Early
     Settlement, Merger Early Settlement of the underlying Forward Purchase
     Contract is effected on the seventh Business Day immediately preceding the
     Stock Purchase Date, an Early Settlement Date or Merger Early Settlement
     Date, as the case may be, or with respect to which a Collateral
     Substitution or an establishment or re-establishment of an Equity Unit has
     been effected, Contract Adjustment Payments, if any, that would otherwise
     be payable after the Early Settlement Date, or Merger Early Settlement
     Date, Collateral Substitution or such establishment or re-establishment
     with respect to such Forward Purchase Contract shall not be payable.

     Section 5.3    Deferral of Contract Adjustment Payments.

                                       35

<PAGE>

          (a) The Company shall have the right, at any time prior to the Stock
     Purchase Date, to defer the payment of any or all of the Contract
     Adjustment Payments otherwise payable on any Payment Date, but only if the
     Company shall give the Holders and the Agent written notice of its election
     to defer each such deferred Contract Adjustment Payment (specifying the
     amount to be deferred) at least ten Business Days prior to the earlier of
     (i) the next succeeding Payment Date or (ii) the date the Company is
     required to give notice of the Record Date or Payment Date with respect to
     payment of such Contract Adjustment Payments to the NYSE or other
     applicable self-regulatory organization or to Holders of the Equity Units
     and Stripped Units, but in any event not less than one Business Day prior
     to such Record Date. Any Contract Adjustment Payments so deferred shall, to
     the extent permitted by law, bear additional Contract Adjustment Payments
     thereon at the rate of 5.75% per year (computed on the basis of a 360-day
     year of twelve 30-day months), compounding on each succeeding Payment Date,
     until paid in full (such deferred installments of Contract Adjustment
     Payments, if any, together with the additional Contract Adjustment Payments
     accrued thereon, being referred to herein as the "Deferred Contract
     Adjustment Payments"). Deferred Contract Adjustment Payments, if any, shall
     be due on the next succeeding Payment Date except to the extent that
     payment is deferred pursuant to this Section 5.3. No Contract Adjustment
     Payments may be deferred to a date that is after the Stock Purchase Date
     and no such deferral period may end other than on a Payment Date. If the
     Forward Purchase Contracts are terminated upon the occurrence of a
     Termination Event, the Holder's right to receive Contract Adjustment
     Payments, if any, and Deferred Contract Adjustment Payments, will
     terminate. If Deferred Contract Adjustment Payments are deferred until the
     Stock Purchase Date, all payments in respect thereof shall be made in cash
     on the Stock Purchase Date.

          (b) In the event that the Company elects to defer the payment of
     Contract Adjustment Payments on the Forward Purchase Contracts until a
     Payment Date prior to the Stock Purchase Date, then all Deferred Contract
     Adjustment Payments, if any, shall be payable to the registered Holders as
     of the close of business on the Record Date immediately preceding such
     Payment Date.

          (c) In the event the Company exercises its option to defer the payment
     of Contract Adjustment Payments then, until the Deferred Contract
     Adjustment Payments have been paid, the Company shall not declare or pay
     dividends on, make distributions with respect to, or redeem, purchase or
     acquire, or make a liquidation payment with respect to, any of the
     Company's Common Stock other than:

               (i)  purchases, redemptions or acquisitions of shares of Common
          Stock in connection with any employment contract, benefit plan or
          other similar arrangement with or for the benefit of employees,
          officers or directors or a stock purchase or dividend reinvestment
          plan, or the satisfaction by the Company of its obligations pursuant
          to any contract or security outstanding on the date the Company
          exercises its right to defer the Contract Adjustment Payments;

               (ii) as a result of a reclassification of the Company's Capital
          Stock or the exchange or conversion of one class or series of the
          Company's Capital Stock for another class or series of the Company's
          Capital Stock;

                                       36

<PAGE>

               (iii) the purchase of fractional interests of the Common Stock
          pursuant to the conversion or exchange provisions of such Common Stock
          or the security being converted or exchanged;

               (iv)  dividends or distributions in any series of the Company's
          Common Stock (or rights to acquire Common Stock) or repurchases,
          acquisitions or redemptions of Common Stock in connection with the
          issuance or exchange of the Common Stock (or securities convertible
          into or exchangeable for shares of the Company's Common Stock); or

               (v)   redemptions, exchanges or repurchases of any rights
          outstanding under a shareholder rights plan or the declaration or
          payment thereunder of a dividend or distribution of or with respect to
          rights in the future.

     Section 5.4    Payment of Purchase Price; Remarketing.

          (a) Unless a Tax Event Redemption, successful remarketing, Termination
     Event, Merger Early Settlement or Early Settlement has occurred, each
     Holder of an Equity Unit may pay in cash ("Cash Settlement") the Purchase
     Price for the shares of Common Stock to be purchased pursuant to a Forward
     Purchase Contract if such Holder notifies the Agent by use of a notice in
     substantially the form of Exhibit E hereto of its intention to make a Cash
     Settlement. Such notice shall be made on or prior to 5:00 p.m., New York
     City time, on the tenth Business Day immediately preceding the Stock
     Purchase Date. The Agent shall promptly notify the Collateral Agent of the
     receipt of such a notice from a Holder intending to make a Cash Settlement.

               (i)   A Holder of an Equity Unit who has so notified the Agent of
          its intention to make a Cash Settlement is required to pay the
          Purchase Price to the Collateral Agent prior to 11:00 a.m., New York
          City time, on the seventh Business Day immediately preceding the Stock
          Purchase Date in lawful money of the United States by certified or
          cashiers' check or wire transfer, in each case payable to or upon the
          order of the Company. Any cash received by the Collateral Agent will
          be paid to the Company on the Stock Purchase Date in settlement of the
          Forward Purchase Contract in accordance with the terms of this
          Agreement and the Pledge Agreement.

               (ii)  If a Holder of an Equity Unit fails to notify the Agent of
          its intention to make a Cash Settlement in accordance with this
          paragraph (a), the Holder shall be deemed to have consented to the
          disposition of the Pledged Notes pursuant to the remarketing as
          described in paragraph 5.4(b) below. If a Holder of an Equity Unit
          does notify the Agent as provided in this paragraph (a) of its
          intention to pay the Purchase Price in cash, but fails to make such
          payment as required by paragraph (a)(i) above, the Holder shall be
          deemed to have consented to the disposition of the Pledged Notes
          pursuant to the remarketing as described in paragraph 5.4 (b) below.

          (b) The Company has engaged the Remarketing Agent to sell the Notes of
     (A) Holders of Equity Units, other than Holders that have elected not to
     participate in the

                                       37

<PAGE>

     remarketing pursuant to the procedures set forth in subsection (g) below,
     and (B) holders of Separate Notes that have elected to participate in the
     remarketing pursuant to the procedures set forth in Section 4.5(d) of the
     Pledge Agreement. On the seventh Business Day prior to the Remarketing
     Date, the Agent shall give Holders of Equity Units and holders of Separate
     Notes notice of the remarketing (the form of which notice to be provided by
     the Company) in a daily newspaper in the English language of general
     circulation in The City of New York, which is expected to be The Wall
     Street Journal, including the specific U.S. Treasury security or securities
     (including the CUSIP number and/or the principal terms of such Treasury
     security or securities) described in subsection (g) below, that must be
     delivered by Holders of Equity Units that elect not to participate in the
     remarketing pursuant to subsection (g) below, no later than 10:00 a.m., New
     York City time, on the fourth Business Day preceding the Remarketing Date
     or the first day of any Subsequent Remarketing Period, as applicable. The
     Agent shall notify, by 10:00 a.m., New York City time, on the third
     Business Day preceding the Remarketing Date or the first day of any
     subsequent Remarketing Period, as applicable, the Remarketing Agent and the
     Collateral Agent of the aggregate number of Notes of Equity Units Holders
     to be remarketed. On the third Business Day immediately preceding the
     Remarketing Date or the first day of any subsequent Remarketing Period, as
     applicable, no later than by 10:00 a.m. New York City time, pursuant to the
     terms of the Pledge Agreement, the Custodial Agent will notify the
     Remarketing Agent of the aggregate number of Separate Notes to be
     remarketed. On the third Business Day immediately preceding the Remarketing
     Date or the first day of any subsequent Remarketing Period, as applicable,
     the Collateral Agent and the Custodial Agent, pursuant to the terms of the
     Pledge Agreement, will deliver for remarketing to the Remarketing Agent all
     Notes to be remarketed.

          (c) Upon receipt of such notice from the Agent and the Custodial Agent
     and such Notes from the Collateral Agent and the Custodial Agent, the
     Remarketing Agent will, on the Remarketing Date, use its commercially
     reasonable best efforts to (i) establish a rate of interest that, in the
     opinion of the Remarketing Agent, will, when applied to the outstanding
     Notes, enable the then current aggregate market value of the Notes to have
     a value equal to approximately, but not less than, 100.25% of the
     Remarketing Value as of the Remarketing Date or as of any Subsequent
     Remarketing Date, as the case may be (the "Reset Rate") and (ii) sell such
     Notes on such date at a price equal to approximately, but not less than,
     100.25% of the Remarketing Value.

          (d) If the remarketing occurs prior to the fourth Business Day
     preceding the Stock Purchase Date, the Remarketing Agent will use the
     proceeds from a successful remarketing to purchase the appropriate U.S.
     Treasury securities (the "Agent-purchased Treasury Consideration") with the
     CUSIP numbers, if any, selected by the Remarketing Agent, described in
     clauses (1) and (2) of the definition of Remarketing Value related to the
     Notes of Holders of Equity Units or that were remarketed. On or prior to
     the third Business Day following the Remarketing Date or any Subsequent
     Remarketing Date the Remarketing Agent shall deliver such Agent-purchased
     Treasury Consideration to the Agent, which shall thereupon deliver such
     Agent-purchased Treasury Consideration to the Collateral Agent. The
     Collateral Agent, for the benefit of the Company, will thereupon apply such
     Agent-purchased Treasury Consideration, in accordance with the Pledge
     Agreement, to secure such Holders' obligations under the Forward Purchase
     Contracts. If the remarketing

                                       38

<PAGE>

     occurs on or after the fourth Business Day preceding the Stock Purchase
     Date, the proceeds of the remarketing will not be used to purchase the
     Agent-purchased Treasury Consideration, but such proceeds will be paid to
     the Agent in direct settlement of the obligations of the Holders under the
     related Forward Purchase Contracts to purchase Common Stock of the Company.
     The Remarketing Agent will deduct as a remarketing fee an amount not
     exceeding 25 basis points (0.25%) of the total proceeds from the
     remarketing (the "Remarketing Fee"). The Remarketing Agent will remit (1)
     the remaining portion of the proceeds from the remarketing attributable to
     the Separate Notes to the Custodial Agent for the benefit of the holders of
     Separate Notes that were remarketed and (2) the remaining portion of the
     proceeds, less those proceeds used to purchase the Agent-purchased Treasury
     Consideration or to pay the Company in direct settlement of the Holders'
     obligations under the Forward Purchase Contracts, to the Agent for payment
     to the Holders of the Equity Units that were remarketed, all determined on
     a pro rata basis, in each case, on or prior to the third Business Day
     following such Remarketing Date or Subsequent Remarketing Date. Holders
     whose Notes are so remarketed will not otherwise be responsible for the
     payment of any Remarketing Fee in connection therewith.

          (e) (i) If, in spite of using its commercially reasonable best
     efforts, the Remarketing Agent cannot establish the Reset Rate and remarket
     the Notes included in the remarketing at a price equal to approximately,
     but not less than, 100.25% of the Remarketing Value, the Remarketing Agent
     will again attempt to establish the Reset Rate and remarket the Notes
     included in the remarketing at a price equal to approximately, but not less
     than, 100.25% of the Remarketing Value on each of the two immediately
     following Business Days. If the Remarketing Agent cannot remarket the Notes
     included in the remarketing at a price equal to approximately, but not less
     than, 100.25% of the Remarketing Value on either of those days, it will
     attempt to establish the Reset Rate and remarket the Notes included in the
     remarketing at a price equal to approximately, but not less than, 100.25%
     of the Remarketing Value on each of the three Business Days immediately
     preceding June 16, 2005. If the Remarketing Agent cannot remarket the Notes
     included in the remarketing at a price equal to approximately, but not less
     than, 100.25% of the Remarketing Value on any of those days, it will
     attempt to establish the Reset Rate and remarket the Notes included in the
     remarketing at a price equal to approximately, but not less than, 100.25%
     of the Remarketing Value on each of the three Business Days immediately
     preceding July 16, 2005. If the Remarketing Agent cannot establish the
     Reset Rate and remarket the Notes included in the remarketing at a price
     equal to approximately, but not less than, 100.25% of the Remarketing Value
     either on any of the two Business Days immediately following the
     Remarketing Date or on any of the three Business Days immediately preceding
     June 16, 2005 or on any of the three Business Days immediately preceding
     July 16, 2005, the remarketing in each period will be deemed to have failed
     (each, a "Failed Remarketing"). If the Remarketing Agent cannot establish
     the Reset Rate and remarket the Notes included in the remarketing at a
     price equal to approximately, but not less than, 100.25% of the Remarketing
     Value on any of the three Business Days immediately preceding July 16,
     2005, the Remarketing Agent will further attempt to establish the Reset
     Rate and remarket the Notes included in the remarketing at a price equal to
     approximately, but not less than, 100.25% of the Remarketing Value on each
     of the three Business Days immediately preceding August 12, 2005. If, in
     spite of using its commercially reasonable best efforts, the Remarketing
     Agent fails to remarket the Notes

                                       39

<PAGE>

     underlying the Equity Units at a price equal to approximately, but not less
     than, 100.25% of the Remarketing Value in accordance with the terms of the
     Pledge Agreement by 4:00 p.m., New York City time, on the third Business
     Day immediately preceding the Stock Purchase Date, a "Last Failed
     Remarketing" will be deemed to have occurred.

               (ii) Within three Business Days following the end of the Last
     Failed Remarketing, the Remarketing Agent shall return any Notes delivered
     to it to the Collateral Agent and the Custodial Agent, as applicable,
     together with written notice from the Remarketing Agent of such Last Failed
     Remarketing. The Collateral Agent, for the benefit of the Company, may
     exercise its rights as a secured party with respect to such Notes,
     including those actions specified in Section 5.4(f) below, and the Holders
     of Equity Units, by their acceptance of the Equity Units shall be deemed to
     have agreed to such exercise by the Collateral Agent in such case;
     provided, that if upon the Last Failed Remarketing, the Collateral Agent
     delivers any Notes to the Company in full satisfaction of the Holder's
     obligation under the related Forward Purchase Contracts, any accumulated
     and unpaid interest on such Notes will become payable by the Company to the
     Agent for payment to the Holder of the Equity Units to which such Notes
     relate. Such payment will be made by the Company on or prior to 11:00 a.m.,
     New York City time, on the Stock Purchase Date in lawful money of the
     United States by certified or cashier's check or wire transfer in
     immediately available funds payable to or upon the order of the Agent. The
     Company will publish notice by means of Bloomberg and Reuters newswires of
     any Remarketing Period during which no successful remarketing occurred,
     such notice to be published not later than the fourth Business Day
     following the end of such Remarketing Period. The Company will also cause a
     notice of the Last Failed Remarketing to be published on the fourth
     Business Day following the date of the Last Failed Remarketing in a daily
     newspaper in the English language of general circulation in The City of New
     York, which is expected to be The Wall Street Journal.

          (f) With respect to any Notes which constitute part of Equity Units
     which are subject to the Last Failed Remarketing, the Collateral Agent for
     the benefit of the Company reserves all of its rights as a secured party
     with respect thereto and, subject to applicable law and Section 5.4 (j)
     below, may, among other things, permit the Company to cause the Notes to be
     sold or to retain and cancel such Notes, in either case, in full
     satisfaction of the Holders' obligations under the Forward Purchase
     Contracts and the Holders of the Equity Units, by their acceptance of the
     Equity Units shall be deemed to have agreed to such action by the
     Collateral Agent.

          (g) A Holder of Equity Units may elect not to participate in the
     remarketing and retain the Notes underlying such Equity Units by notifying
     the Agent of such election and delivering the specific U.S. Treasury
     security or securities (including the CUSIP number and/or the principal
     terms of such security or securities) identified by the Agent that
     constitute the U.S. Treasury securities described in clauses (1) and (2) of
     the definition of Remarketing Value relating to the retained Notes (as if
     only such Notes were being remarketed) (the "Opt-out Treasury
     Consideration") to the Agent not later than 10:00 a.m. on the fourth
     Business Day prior to the Remarketing Date (or, in the case of a Failed
     Remarketing, not later than 10:00 a.m. on the fourth Business Day
     immediately prior to the subsequent Remarketing Period). Upon receipt
     thereof by the Agent, the Agent shall

                                       40

<PAGE>

     deliver such Opt-out Treasury Consideration to the Collateral Agent, which
     will, for the benefit of the Company, thereupon apply such Opt-out Treasury
     Consideration to secure such Holder's obligations under the Forward
     Purchase Contracts. On the first Business Day immediately preceding the
     Remarketing Date (or, in the case of a Failed Remarketing, the subsequent
     Remarketing Period), the Collateral Agent, pursuant to the terms of the
     Pledge Agreement, will deliver the Pledged Notes of such Holder to the
     Agent. Within three Business Days following any Remarketing Period, (A) if
     the remarketing was successful, the Agent shall distribute such Notes to
     the new holders thereof, and (B) if there was a Failed Remarketing, the
     Agent will deliver such Notes to the Collateral Agent, which will, for the
     benefit of the Company, thereupon apply such Notes to secure such Holders'
     obligations under the Forward Purchase Contracts and return the Opt-out
     Treasury Consideration delivered by such Holders to such Holders. A Holder
     that does not so deliver the Opt-out Treasury Consideration pursuant to
     this clause (g) shall be deemed to have elected to participate in the
     remarketing.

          (h) Upon the maturity of the Pledged Treasury Securities underlying
     the Stripped Units and the Pledged Treasury Consideration or Pledged
     Applicable Ownership Interest in the Treasury Portfolio, as the case may
     be, underlying the Equity Units, on the Stock Purchase Date, the Collateral
     Agent shall remit to the Company an amount equal to the aggregate Purchase
     Price applicable to such Units, as payment for the Common Stock issuable
     upon settlement thereof without receiving any instructions from the Holders
     of such Units. In the event the payments in respect of the Pledged Treasury
     Securities, Pledged Treasury Consideration or Pledged Applicable Ownership
     Interest in the Treasury Portfolio underlying a Unit are in excess of the
     Purchase Price under the Forward Purchase Contract being settled thereby,
     the Collateral Agent will distribute such excess to the Agent for the
     benefit of the Holder of such Units when received.

          (i) Any distribution to Holders of excess funds and interest described
     in Section 5.4(c) and (d) above shall be payable at the Office of the Agent
     in The City of New York maintained for that purpose or, at the option of
     the Holder or the holder of Separate Notes, as applicable, by check mailed
     to the address of the Person entitled thereto at such address as it appears
     on the relevant Register or by wire transfer to an account specified by the
     Holder or the holder of Separate Notes, as applicable.

          (j) The obligations of each Holder to pay the Purchase Price are
     non-recourse obligations and except to the extent paid by Cash Settlement,
     Early Settlement or Merger Early Settlement, are payable solely out of the
     proceeds of any Collateral pledged to secure the obligations of the Holder,
     and in no event will any Holder be liable for any deficiency between such
     proceeds and the Purchase Price.

          (k) Notwithstanding anything to the contrary herein, the Company shall
     not be obligated to issue any Common Stock in respect of a Forward Purchase
     Contract or deliver any certificates therefor to the Holder of the related
     Equity Units or Stripped Units, as the case may be, unless the Company
     shall have received payment in full for the shares of Common Stock to be
     purchased thereunder by such Holder in the manner herein set forth.

                                       41

          (l) In the event of a successful remarketing, the interest rate on all
     of the outstanding Notes (whether or not included in the remarketing) shall
     be adjusted to the Reset Rate.

     Section 5.5    Issuance of Shares of Common Stock.

     Unless a Termination Event shall have occurred on or prior to the Stock
Purchase Date or an Early Settlement or a Merger Early Settlement shall have
occurred with respect to all of the outstanding Units, on the Stock Purchase
Date, upon its receipt of payment for the shares of Common Stock purchased by
the Holders pursuant to the provisions of this Article and subject to Section
5.4, the Company shall issue and deposit with the Agent, for the benefit of the
Holders of the Outstanding Units, one or more certificates or book-entry
interests representing the newly issued shares of Common Stock registered in the
name of the Agent (or its nominee) as custodian for the Holders (such
certificates or book-entry interests for shares of Common Stock, together with
any dividends or distributions for which a record date and payment date for such
dividend or distribution has occurred after the Stock Purchase Date, being
hereinafter referred to as the "Forward Purchase Contract Settlement Fund") to
which the Holders are entitled hereunder. Subject to the foregoing, upon
surrender of a Certificate to the Agent on or after the Stock Purchase Date,
together with settlement instructions thereon duly completed and executed, the
Holder of such Certificate shall be entitled to receive in exchange therefor a
certificate or book-entry interest representing that number of whole shares of
Common Stock which such Holder is entitled to receive pursuant to the provisions
of this Article V (after taking into account all Equity Units and Stripped Units
then held by such Holder) together with cash in lieu of fractional shares as
provided in Section 5.12 and any dividends or distributions with respect to such
shares constituting part of the Forward Purchase Contract Settlement Fund, but
without any interest thereon, and the Certificate so surrendered shall forthwith
be cancelled. Such shares shall be registered in the name of the Holder or the
Holder's designee as specified in the settlement instructions provided by the
Holder to the Agent. If any shares of Common Stock issued in respect of a
Forward Purchase Contract are to be registered to a Person other than the Person
in whose name the Certificate evidencing such Forward Purchase Contract is
registered, no such registration shall be made unless the Person requesting such
registration has paid any transfer and other taxes required by reason of such
registration in a name other than that of the registered Holder of such
Certificate or has established to the satisfaction of the Company that such tax
either has been paid or is not payable.

     Section 5.6    Adjustment of Settlement Rate.

          (a) Adjustments for Dividends, Distributions, Stock Splits, Etc.

                         (l) Stock Dividends. In case the Company shall pay or
                    make a dividend or other distribution on the Common Stock in
                    Common Stock, the Settlement Rate or Early Settlement Rate,
                    as applicable, as in effect at the opening of business on
                    the day following the date fixed for the determination of
                    stockholders entitled to receive such dividend or other
                    distribution shall be increased by dividing such Settlement
                    Rate or Early Settlement Rate by a fraction of which the
                    numerator shall be the number of shares of Common Stock
                    outstanding at the close of business on the date

                                       42

<PAGE>

                    fixed for such determination and the denominator shall be
                    the sum of such number of shares and the total number of
                    shares constituting such dividend or other distribution,
                    such increase to become effective immediately after the
                    opening of business on the day following the date fixed for
                    such determination. For the purposes of this paragraph (1),
                    the number of shares of Common Stock at the time outstanding
                    shall not include shares held in the treasury of the Company
                    but shall include any shares issuable in respect of any
                    scrip certificates issued in lieu of fractions of shares of
                    Common Stock. The Company will not pay any dividend or make
                    any distribution on shares of Common Stock held in the
                    treasury of the Company.

                         (2) Stock Purchase Rights. In case the Company shall
                    issue rights, options or warrants to all holders of its
                    Common Stock (not being available on an equivalent basis to
                    Holders of the Equity Units and Stripped Units upon
                    settlement of the Forward Purchase Contracts underlying such
                    Equity Units and Stripped Units) entitling them to subscribe
                    for or purchase shares of Common Stock at a price per share
                    less than the Current Market Price per share of the Common
                    Stock on the date fixed for the determination of
                    stockholders entitled to receive such rights, options or
                    warrants (other than pursuant to a dividend reinvestment,
                    share purchase or similar plan), the Settlement Rate or
                    Early Settlement Rate, as applicable, in effect at the
                    opening of business on the day following the date fixed for
                    such determination shall be increased by dividing such
                    Settlement Rate or Early Settlement Rate, as applicable, by
                    a fraction, the numerator of which shall be the number of
                    shares of Common Stock outstanding at the close of business
                    on the date fixed for such determination plus the number of
                    shares of Common Stock which the aggregate of the offering
                    price of the total number of shares of Common Stock so
                    offered for subscription or purchase would purchase at such
                    Current Market Price and the denominator of which shall be
                    the number of shares of Common Stock outstanding at the
                    close of business on the date fixed for such determination
                    plus the number of shares of Common Stock so offered for
                    subscription or purchase, such increase to become effective
                    immediately after the opening of business on the day
                    following the date fixed for such determination. For the
                    purposes of this paragraph (2), the number of shares of
                    Common Stock at any time outstanding shall not include
                    shares held in the treasury of the Company but shall include
                    any shares issuable in respect of any scrip certificates
                    issued in lieu of fractions of shares of Common Stock. The
                    Company shall not issue any such rights, options or warrants
                    in respect of shares of Common Stock held in the treasury of
                    the Company.

                         (3) Stock Splits; Reverse Splits. In case outstanding
                    shares of Common Stock shall be subdivided or split into a
                    greater number of shares of Common Stock, the Settlement
                    Rate or Early Settlement Rate, as applicable, in effect at
                    the opening of business on the day following the day upon
                    which such subdivision or split becomes effective shall be
                    proportionately increased, and, conversely, in case
                    outstanding shares of

                                       43

<PAGE>

                    Common Stock shall be combined into a smaller number of
                    shares of Common Stock, the Settlement Rate or Early
                    Settlement Rate, as applicable, in effect at the opening of
                    business on the day following the day upon which such
                    combination becomes effective shall be proportionately
                    reduced, such increase or reduction, as the case may be, to
                    become effective immediately after the opening of business
                    on the day following the day upon which such subdivision,
                    split or combination becomes effective.

                         (4) Debt or Asset Distributions. (i) In case the
                    Company shall, by dividend or otherwise, distribute to all
                    holders of its Common Stock evidences of its indebtedness or
                    assets (including securities, but excluding any rights or
                    warrants referred to in paragraph (2) of this Section, any
                    dividend or distribution paid exclusively in cash and any
                    dividend, shares of capital stock of any class or series, or
                    similar equity interests, of or relating to a subsidiary or
                    other business unit in the case of a Spin-Off referred to in
                    the next paragraph, or distribution referred to in paragraph
                    (1) of this Section), the Settlement Rate or Early
                    Settlement Rate, as applicable, shall be adjusted so that
                    the same shall equal the rate determined by dividing the
                    Settlement Rate or Early Settlement Rate, as applicable, in
                    effect immediately prior to the close of business on the
                    date fixed for the determination of stockholders entitled to
                    receive such distribution by a fraction, the numerator of
                    which shall be the Current Market Price per share of the
                    Common Stock on the date fixed for such determination less
                    the then fair market value (as determined by the Board of
                    Directors, whose determination shall be conclusive and
                    described in a Board Resolution) of the portion of the
                    assets or evidences of indebtedness so distributed
                    applicable to one share of Common Stock and the denominator
                    of which shall be such Current Market Price per share of the
                    Common Stock, such adjustment to become effective
                    immediately prior to the opening of business on the day
                    following the date fixed for the determination of
                    stockholders entitled to receive such distribution. In any
                    case in which this paragraph (4) is applicable, paragraph
                    (2) of this Section shall not be applicable.

                    (ii)  In the case of a Spin-Off, the Settlement Rate or
     Early Settlement Rate, as applicable, in effect immediately before the
     close of business on the record date fixed for determination of
     stockholders entitled to receive that distribution will be increased by
     multiplying the Settlement Rate or Early Settlement Rate, as applicable, by
     a fraction, the numerator of which is the Current Market Price per share of
     the Common Stock plus the Fair Market Value of the portion of those shares
     of Capital Stock or similar equity interests so distributed applicable to
     one share of Common Stock and the denominator of which is the Current
     Market Price per share of the Common Stock. Any adjustment to the
     Settlement Rate or Early Settlement Rate under this paragraph 4(ii) will
     occur at the earlier of (1) the tenth Trading Day from, and including, the
     effective date of the Spin-Off and (2) the date of the securities being
     offered in the Initial Public Offering of the Spin-Off, if that Initial
     Public Offering is effected simultaneously with the Spin-Off.

                         (5)  Cash Distributions. In case the Company shall, (i)
                    by dividend or otherwise, distribute to all holders of its
                    Common Stock cash (excluding any cash that is distributed in
                    a Reorganization Event to which Section 5.6(b) applies or as
                    part of a distribution referred to in paragraph (4) of this
                    Section) in an aggregate amount that, combined together with
                    (ii) the aggregate amount of any other distributions to all
                    holders of its Common Stock made exclusively in cash within
                    the 12 months preceding the date of payment of such
                    distribution and in respect of which no adjustment pursuant
                    to this paragraph (5) or paragraph (6) of this Section has
                    been made and (iii) the aggregate of any cash plus the fair
                    market value as of the date of the expiration of the tender
                    or exchange offer referred to below (as determined by the
                    Board of Directors, whose determination shall be conclusive
                    and described in a Board Resolution) of consideration
                    payable in respect of any tender or exchange offer by the
                    Company or any of its subsidiaries for all or any portion of
                    the Common Stock concluded within the 12 months preceding
                    the date of payment of the distribution described in clause
                    (i) above and in respect of which no adjustment pursuant to
                    this paragraph (5) or paragraph (6) of this Section has been
                    made, exceeds 15% of the product of the Current Market Price
                    per share of the Common Stock on the date for the
                    determination of holders of shares of Common Stock entitled
                    to receive such distribution times the number of shares of
                    Common Stock outstanding on such date, then, and in each
                    such case, immediately after the close of business on such
                    date for determination, the Settlement Rate or Early
                    Settlement Rate, as applicable, shall be increased so that
                    the same shall equal the rate determined by dividing the
                    Settlement Rate or Early Settlement Rate, as applicable, in
                    effect immediately prior to the close of business on the
                    date fixed for determination of the stockholders entitled to
                    receive such distribution by a fraction (A) the numerator of
                    which shall be equal to the Current Market Price per share
                    of the Common Stock on the date fixed for such determination
                    less an amount equal to the quotient of (x) the combined
                    amount distributed or payable in the transactions described
                    in clauses (i), (ii) and (iii) above and (y) the number of
                    shares of Common Stock outstanding on such date for
                    determination and (B) the denominator of which shall be
                    equal to the Current Market Price per share of the Common
                    Stock on such date for determination.

                         (6)  Tender Offers. In case (i) a tender or exchange
                    offer made by the Company or any subsidiary of the Company
                    for all or any portion of the Common Stock shall expire and
                    such tender or exchange offer (as amended upon the
                    expiration thereof) shall require the payment to
                    stockholders (based on the acceptance (up to any maximum
                    specified in the terms of the tender or exchange offer) of
                    Purchased Shares) of an aggregate consideration having a
                    fair market value (as determined by the Board of Directors,
                    whose determination shall be conclusive and described in a
                    Board Resolution) that combined together with (ii) the
                    aggregate of the cash plus the fair market value (as
                    determined by the Board of Directors, whose determination
                    shall be conclusive and described in a Board Resolution), as

                    consideration payable in respect of any other tender or
                    exchange offer, by the Company or any subsidiary of the
                    Company for all or any portion of the Common Stock expiring
                    within the 12 months preceding the expiration of such tender
                    or exchange offer and in respect of which no adjustment
                    pursuant to paragraph (5) of this Section or this paragraph
                    (6) has been made and (iii) the aggregate amount of any
                    distributions to all holders of the Company's Common Stock
                    made exclusively in cash within the 12 months preceding the
                    expiration of such tender or exchange offer and in respect
                    of which no adjustment pursuant to paragraph (5) of this
                    Section or this paragraph (6) has been made, exceeds 15% of
                    the product of the Current Market Price per share of the
                    Common Stock as of the last time (the "Expiration Time")
                    tenders could have been made pursuant to such tender or
                    exchange offer (as it may be amended) times the number of
                    shares of Common Stock outstanding (including any tendered
                    shares) at the Expiration Time, then, and in each such case,
                    immediately prior to the opening of business on the day
                    after the date of the Expiration Time, the Settlement Rate
                    or Early Settlement Rate, as applicable, shall be adjusted
                    so that the same shall equal the rate determined by dividing
                    the Settlement Rate or Early Settlement Rate, as applicable,
                    immediately prior to the close of business on the date of
                    the Expiration Time by a fraction (A) the numerator of which
                    shall be equal to (x) the product of (I) the Current Market
                    Price per share of the Common Stock on the date of the
                    Expiration Time and (II) the number of shares of Common
                    Stock outstanding (including any tendered shares) at the
                    Expiration Time less (y) the amount of cash plus the fair
                    market value (determined as aforesaid) of the aggregate
                    consideration payable to stockholders based on the
                    transactions described in clauses (i), (ii) and (iii) above
                    (assuming in the case of clause (i) the acceptance, up to
                    any maximum specified in the terms of the tender or exchange
                    offer, of Purchased Shares), and (B) the denominator of
                    which shall be equal to the product of (x) the Current
                    Market Price per share of the Common Stock as of the
                    Expiration Time and (y) the number of shares of Common Stock
                    outstanding (including any tendered shares) as of the
                    Expiration Time less the number of all shares validly
                    tendered and not withdrawn as of the Expiration Time (the
                    shares deemed so accepted, up to any such maximum, being
                    referred to as the "Purchased Shares").

                         (7)  Reclassification. The reclassification of Common
                    Stock into securities including securities other than Common
                    Stock (other than any reclassification upon a Reorganization
                    Event to which Section 5.6(b) applies) shall be deemed to
                    involve (i) a distribution of such securities other than
                    Common Stock to all holders of Common Stock (and the
                    effective date of such reclassification shall be deemed to
                    be "the date fixed for the determination of stockholders
                    entitled to receive such distribution" and the "date fixed
                    for such determination" within the meaning of paragraph (4)
                    of this Section), and (ii) a subdivision, split or
                    combination, as the case may be, of the number of shares of
                    Common Stock outstanding immediately

                                       46

<PAGE>

                    prior to such reclassification into the number of shares of
                    Common Stock outstanding immediately thereafter (and the
                    effective date of such reclassification shall be deemed to
                    be "the day upon which such subdivision or split becomes
                    effective" or "the day upon which such combination becomes
                    effective," as the case may be, and "the day upon which such
                    subdivision, split or combination becomes effective" within
                    the meaning of paragraph (3) of this Section).

                         (8)  "Current Market Price". The "Current Market Price"
                    of the Common Stock means (a) on any day the average of the
                    Sales Prices for the 5 consecutive Trading Days preceding
                    the earlier of the day preceding the day in question and the
                    day before the "ex date" with respect to the issuance or
                    distribution requiring computation, (b) in the case of any
                    Spin-Off that is effected simultaneously with an Initial
                    Public Offering of the securities being distributed in the
                    Spin-Off, the Sale Price of the Common Stock on the Trading
                    Day on which the Initial Public Offering price of the
                    securities being distributed in the Spin-Off is determined,
                    and (c) in the case of any other Spin-Off, the average of
                    the Sale Prices of the Common Stock over the first 10
                    Trading Days after the effective date of such Spin-Off. For
                    purposes of this paragraph, the term "ex date," when used
                    with respect to any issuance or distribution, shall mean the
                    first date on which the Common Stock trades regular way on
                    the relevant exchange or in the relevant market without the
                    right to receive such issuance or distribution.

                         (9)  Calculation of Adjustments. All adjustments to the
                    Settlement Rate or Early Settlement Rate, as applicable,
                    shall be calculated to the nearest 1/10,000th of a share of
                    Common Stock (or if there is not a nearest 1/10,000th of a
                    share to the next lower 1/10,000th of a share). No
                    adjustment in the Settlement Rate or Early Settlement Rate,
                    as applicable, shall be required unless such adjustment
                    would require an increase or decrease of at least one
                    percent therein; provided, that any adjustments which by
                    reason of this subparagraph are not required to be made
                    shall be carried forward and taken into account in any
                    subsequent adjustment. If an adjustment is made to the
                    Settlement Rate or Early Settlement Rate, as applicable,
                    pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or
                    (10) of this Section 5.6(a), an adjustment shall also be
                    made to the Applicable Market Value solely to determine
                    which of clauses (i), (ii) or (iii) of the definition of
                    Settlement Rate or Early Settlement Rate, as applicable, in
                    Section 5.1(a) will apply on the Stock Purchase Date. Such
                    adjustment shall be made by multiplying the Applicable
                    Market Value by a fraction, the numerator of which shall be
                    the Settlement Rate or Early Settlement Rate, as applicable,
                    immediately after such adjustment pursuant to paragraph (1),
                    (2), (3), (4), (5), (6), (7) or (10) of this Section 5.6(a)
                    and the denominator of which shall be the Settlement Rate or
                    Early Settlement Rate, as applicable, immediately before
                    such adjustment; provided, that if such adjustment to the
                    Settlement Rate or Early Settlement Rate, as applicable, is
                    required to be made pursuant to the occurrence of any of the
                    events contemplated by paragraph

                                       47

<PAGE>

                    (1), (2), (3), (4), (5), (7) or (10) of this Section 5.6(a)
                    during the period taken into consideration for determining
                    the Applicable Market Value, appropriate and customary
                    adjustments shall be made to the Settlement Rate or Early
                    Settlement Rate, as applicable.

                         (10) Increase of Settlement Rate. The Company may make
                    such increases in the Settlement Rate or Early Settlement
                    Rate, as applicable, in addition to those required by this
                    Section, as it considers to be advisable in order to avoid
                    or diminish any income tax to any holders of shares of
                    Common Stock resulting from any dividend or distribution of
                    stock or issuance of rights or warrants to purchase or
                    subscribe for stock or from any event treated as such for
                    income tax purposes or for any other reasons.

          (b) Adjustment for Consolidation, Merger or Other Reorganization
          Event.

                    In the event of

                         (1) any consolidation or merger of the Company with or
                    into another Person (other than a merger or consolidation in
                    which the Company is the continuing corporation and in which
                    the Common Stock outstanding immediately prior to the merger
                    or consolidation is not exchanged for cash, securities or
                    other property of the Company or another corporation),

                         (2) any sale, transfer, lease or conveyance to another
                    Person of the property of the Company as an entirety or
                    substantially as an entirety,

                         (3) any statutory exchange of securities of the Company
                    with another Person (other than in connection with a merger
                    or acquisition), or

                         (4) any liquidation, dissolution or winding up of the
                    Company other than as a result of or after the occurrence of
                    a Termination Event (any such event, a "Reorganization
                    Event"),

each share of Common Stock covered by each Forward Purchase Contract forming a
part of an Equity Unit or Stripped Unit, as the case may be, immediately prior
to such Reorganization Event shall, after such Reorganization Event, be
converted for purposes of the Forward Purchase Contract into the kind and amount
of securities, cash and other property receivable in such Reorganization Event
(without any interest thereon, and without any right to dividends or
distributions thereon which have a record date that is prior to the Stock
Purchase Date) per share of Common Stock by a holder of Common Stock that (i) is
not a Person with which the Company consolidated or into which the Company
merged or which merged into the Company or to which such sale or transfer was
made, as the case may be (any such Person, a "Constituent Person"), or an
Affiliate of a Constituent Person to the extent such Reorganization Event
provides for different treatment of Common Stock held by Affiliates of the
Company and non-Affiliates, and (ii) failed to exercise his rights of election,
if any, as to the kind or amount of securities, cash and other property
receivable upon such Reorganization Event (provided that if the kind or amount
of securities, cash and other property receivable upon such Reorganization Event
is not the same for each share of Common Stock held immediately prior to such
Reorganization Event by other than a

                                       48

<PAGE>

Constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("Non-electing Share"), then for the
purpose of this Section the kind and amount of securities, cash and other
property receivable upon such Reorganization Event by each Non-electing Share
shall be deemed to be the kind and amount so receivable per share by a plurality
of the Non-electing Shares). On the Stock Purchase Date, the Settlement Rate
then in effect will be applied to the value on the Stock Purchase Date of such
securities, cash or other property. In the event of such a Reorganization Event,
the Person formed by such consolidation, merger or exchange or the Person which
acquires the assets of the Company or, in the event of a liquidation or
dissolution of the Company, the Company or a liquidating trust created in
connection therewith, shall execute and deliver to the Agent an agreement
supplemental hereto providing that the Holder of each Outstanding Unit shall
have the rights provided by this Section 5.6. Such supplemental agreement shall
provide for adjustments which, for events subsequent to the effective date of
such supplemental agreement, shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Section. The above provisions of this
Section shall similarly apply to successive Reorganization Events.

     Section 5.7    Notice of Adjustments and Certain Other Events.

          (a) Whenever the Settlement Rate or Early Settlement Rate, as
     applicable, is adjusted as herein provided, the Company shall:

               (i)  forthwith compute the Settlement Rate or Early Settlement
          Rate, as applicable, and the Applicable Market Value in accordance
          with Section 5.6 and prepare and transmit to the Agent an Officer's
          Certificate setting forth the Settlement Rate and the Applicable
          Market Value, the method of calculation thereof in reasonable detail,
          and the facts requiring such adjustment and upon which such adjustment
          is based; and

               (ii) as soon as practicable following the occurrence of an event
          that requires an adjustment to the Settlement Rate or Early Settlement
          Rate, as applicable, pursuant to Section 5.6 (or if the Company is not
          aware of such occurrence, as soon as practicable after becoming so
          aware), provide a written notice to the Holders of the Equity Units
          and Stripped Units of the occurrence of such event and a statement in
          reasonable detail setting forth the method by which the adjustment to
          the Settlement Rate or Early Settlement Rate, as applicable, and the
          Applicable Market Value was determined and setting forth the adjusted
          Settlement Rate or Early Settlement Rate, as applicable, and the
          Applicable Market Value.

          (b) The Agent shall not at any time be under any duty or
     responsibility to any Holder of Equity Units and Stripped Units to
     determine whether any facts exist which may require any adjustment of the
     Settlement Rate or Early Settlement Rate, as applicable, and the Applicable
     Market Value, or with respect to the nature or extent or calculation of any
     such adjustment when made, or with respect to the method employed in making
     the same. The Agent shall not be accountable with respect to the validity
     or value (or the kind or amount) of any shares of Common Stock, or of any
     securities or property, which may at any time be issued or delivered with
     respect to any Forward Purchase Contract; and the

                                       49

<PAGE>

     Agent makes no representation with respect thereto. The Agent shall not be
     responsible for any failure of the Company to issue, transfer or deliver
     any shares of Common Stock pursuant to a Forward Purchase Contract or to
     comply with any of the duties, responsibilities or covenants of the Company
     contained in this Article.

     Section 5.8    Termination Event; Notice.

     The Forward Purchase Contracts and all obligations and rights of the
Company and the Holders thereunder, including the rights and obligations of
Holders to purchase Common Stock, 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 Stock Purchase Date, a Termination Event shall
have occurred. Upon and after the occurrence of a Termination Event, the Equity
Units shall thereafter represent the right to receive the Notes or the
appropriate Treasury Consideration or Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, forming a part of such Equity Units, and
the Stripped Units shall thereafter represent the right to receive the Treasury
Securities forming a part of such Stripped Units, in each case in accordance
with the provisions of Section 4.3 of the Pledge Agreement. 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 to the Holders, at their addresses as they appear in the applicable
Register.

     Section 5.9    Early Settlement.

          (a) Subject to and upon compliance with the provisions of this Section
     5.9, Forward Purchase Contracts underlying Equity Units or Stripped Units
     may, at the option of the Holder thereof, be settled early ("Early
     Settlement") at any time not later than 10:00 a.m. on the seventh Business
     Day immediately preceding the Stock Purchase Date. In order to exercise the
     right to effect Early Settlement with respect to any Forward Purchase
     Contracts, the Holder of the Certificate evidencing the related Equity
     Units or Stripped Units, as the case may be, shall deliver such 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 on the
     reverse thereof duly completed and accompanied by payment payable to the
     Company in immediately available funds in an amount (the "Early Settlement
     Amount") equal to (A) the product of (i) the Stated Amount of such Equity
     Units or Stripped Units, as the case may be, multiplied by (ii) the number
     of Forward Purchase Contracts with respect to which the Holder has elected
     to effect Early Settlement, plus (B) if such delivery is made with respect
     to any Forward Purchase Contracts during the period from the close of
     business on any Record Date next preceding any Payment Date to the opening
     of business on such Payment Date, an amount equal to the Contract
     Adjustment Payments, if any, payable on such Payment Date with respect to
     such Forward Purchase Contracts; provided that no payment shall be required
     pursuant to clause (B) of this sentence if the Company shall have elected
     to defer the Contract Adjustment Payments that would otherwise be payable
     on such Payment Date and further provided that, at that time, if so
     required by the United States federal securities laws, a registration
     statement is in effect and a prospectus is available covering the shares of
     the Common Stock of the Company to be delivered in respect of the Forward
     Purchase Contracts being settled. Except as provided in the immediately
     preceding sentence and subject to Section 5.2(d), no

                                       50

<PAGE>

     payment or adjustment shall be made upon Early Settlement of any Forward
     Purchase Contract on any Contract Adjustment Payments accrued on such
     Forward Purchase Contract or on account of any dividends on the Common
     Stock issued upon such Early Settlement. If the foregoing requirements are
     first satisfied with respect to Forward Purchase Contracts underlying any
     Equity Units or Stripped Units, as the case may be, at or prior to 5:00
     p.m., New York City time, on a Business Day, such day shall be the "Early
     Settlement Date" with respect to such Equity Units or Stripped Units, as
     the case may be, and if such requirements are first satisfied after 5:00
     p.m., New York City time, on a Business Day or on a day that is not a
     Business Day, the "Early Settlement Date" with respect to such Equity Units
     or Stripped Units, as the case may be, shall be the next succeeding
     Business Day.

          (b) Holders of Equity Units may settle only in units of 20 and
     integral multiples of 20. If a successful remarketing or a Tax Event
     Redemption has occurred, Holders of Stripped Units may effect Early
     Settlement pursuant to this Section 5.9 only in integral multiples of
     32,000.

          (c) Upon Early Settlement of any Forward Purchase Contract by the
     Holder of the related Equity Units or Stripped Units, as the case may be,
     the Company shall issue, and the Holder shall be entitled to receive,
     1.0187 shares of Common Stock for each Equity Unit or Stripped Unit on
     account of such Forward Purchase Contract (the "Early Settlement Rate").
     The Early Settlement Rate shall be adjusted in the same manner and at the
     same time as the Settlement Rate is adjusted. As promptly as practicable
     after Early Settlement of Forward Purchase Contracts in accordance with the
     provisions of this Section 5.9, the Company shall issue and shall deliver
     to the Agent at the Corporate Trust Office a certificate or certificates or
     book entry interest for the full number of shares of Common Stock issuable
     upon such Early Settlement together with payment in lieu of any fraction of
     a share, as provided in Section 5.12.

          (d) No later than the third Business Day after the applicable Early
     Settlement Date the Company shall cause (i) the shares of Common Stock
     issuable upon Early Settlement of Forward Purchase Contracts to be issued
     and delivered, and (ii) the related Pledged Notes or Pledged Treasury
     Consideration or Pledged Applicable Ownership Interest in the Treasury
     Portfolio, in the case of Equity Units, or the related Pledged Treasury
     Securities, in the case of Stripped Units, to be released from the Pledge
     by the Collateral Agent and transferred, in each case, to the Agent for
     delivery to the Holder thereof or the Holder's designee.

          (e) Upon Early Settlement of any Forward Purchase Contracts, and
     subject to receipt of shares of Common Stock from the Company and the
     Pledged Notes, Pledged Treasury Consideration, Pledged Applicable Ownership
     Interest in the Treasury Portfolio, or Pledged Treasury Securities, as the
     case may be, from the Collateral Agent, as applicable, the Agent shall, in

     Certificate evidencing the related Equity Units or Stripped Units, as the
     case may be, (i) transfer to the Holder the Pledged Notes, Pledged Treasury

     may be, and (ii) deliver to the Holder a certificate or certificates or
     book-entry interest for the full number of shares of Common Stock issuable

          (f) In the event that Early Settlement is effected with respect to
     Forward Purchase Contracts underlying less than all the Equity Units or

     Early Settlement the Company shall execute and the Agent shall
     authenticate, execute on behalf of the Holder thereof and deliver to the
     Holder thereof, at the expense of the Company, a Certificate evidencing the
     Equity Units or Stripped Units, as the case may be, as to which Early
     Settlement was not effected.

     Section 5.10   Early Settlement Upon Merger.

          (a) In the event of a merger or consolidation of the Company of the
     type described in clause (1) of Section 5.6(b) in which the Common Stock
     outstanding immediately prior to such merger or consolidation is exchanged
     for consideration consisting of at least 30% cash or cash equivalents (any
     such event a "Cash Merger"), then the Company (or the successor to the
     Company hereunder) shall be required to offer the Holder of each Equity
     Unit or Stripped Unit, as the case may be, the right to settle the Forward
     Purchase Contract underlying such Equity Units or Stripped Units, as the
     case may be, prior to the Stock Purchase Date ("Merger Early Settlement")
     as provided herein. On or before the fifth Business Day after the
     consummation of a Cash Merger, the Company or, at the request and expense
     of the Company, the Agent, shall give all Holders notice of the occurrence
     of the Cash Merger and of the right of Merger Early Settlement arising as a
     result thereof. The Company shall also deliver a copy of such notice to the
     Agent and the Collateral Agent.

          Each such notice shall contain:

               (i)    the date, which shall be not less than 20 nor more than 30
          calendar days after the date of such notice, on which the Merger Early
          Settlement will be effected (the "Merger Early Settlement Date");

               (ii)   the date, which shall be on or one Business Day prior to
          the Merger Early Settlement Date, by which the Merger Early Settlement
          right must be exercised;

               (iii)  the Settlement Rate in effect as a result of such Cash
          Merger and the kind and amount of securities, cash and other property
          receivable by the Holder upon settlement of each Forward Purchase
          Contract pursuant to Section 5.6(b);

               (iv)   a statement to the effect that all or a portion of the
          Purchase Price payable by the Holder to settle the Forward Purchase
          Contract will be offset against the amount of cash so receivable upon
          exercise of Merger Early Settlement, as applicable; and

               (v)    the instructions a Holder must follow to exercise the
          Merger Early Settlement right.

                  (b) To exercise a Merger Early Settlement right, a Holder
         shall deliver to the Agent at the Corporate Trust Office on or before
         5:00 p.m., New York City time on the date specified in the notice the
         Certificate(s) evidencing the Equity Units or Stripped Units, as the
         case may be, with respect to which the Merger Early Settlement right is
         being exercised duly endorsed for transfer to the Company or in blank
         with the form of Election to Settle Early on the reverse thereof duly
         completed and accompanied by payment payable to the Company in
         immediately available funds in an amount equal to the Early Settlement
         Amount less the amount of cash that otherwise would be deliverable by
         the Company or its successor upon settlement of the Forward Purchase
         Contract in lieu of Common Stock pursuant to Section 5.4(b) and as
         described in the notice to Holders (the "Merger Early Settlement
         Amount").

                  (c) On the Merger Early Settlement Date, the Company shall
         deliver or cause to be delivered (i) the net cash, securities and other
         property to be received by such exercising Holder, equal to the
         Settlement Rate as adjusted pursuant to Section 5.6, in respect of the
         number of Forward Purchase Contracts for which such Merger Early
         Settlement right was exercised, and (ii) the related Pledged Notes,
         Pledged Treasury Consideration or Pledged Applicable Ownership Interest
         in the Treasury Portfolio, in the case of Equity Units, or Pledged
         Treasury Securities, in the case of Stripped Units, to be released from
         the Pledge by the Collateral Agent and transferred, in each case, to
         the Agent for delivery to the Holder thereof or its designee. In the
         event a Merger Early Settlement right shall be exercised by a Holder in
         accordance with the terms hereof, all references herein to the Stock
         Purchase Date shall be deemed to refer to such Merger Early Settlement
         Date.

                  (d) Upon Merger Early Settlement of any Forward Purchase
         Contracts, and subject to receipt of such net cash, securities or other
         property from the Company and the Pledged Notes, Pledged Treasury
         Consideration, Pledged Applicable Ownership Interest in the Treasury
         Portfolio or Pledged Treasury Securities, as the case may be, from the
         Collateral Agent, as applicable, the Agent shall, in accordance with
         the instructions provided by the Holder thereof on the applicable form
         of Election to Settle Early on the reverse of the Certificate
         evidencing the related Equity Units or Stripped Units, as the case may
         be, (i) transfer to the Holder the Pledged Notes, Pledged Treasury
         Consideration, Pledged Applicable Ownership Interest in the Treasury
         Portfolio, or Pledged Treasury Securities, as the case may be, forming
         a part of such Equity Units or Stripped Units, as the case may be, and
         (ii) deliver to the Holder such net cash, securities or other property
         issuable upon such Merger Early Settlement together with payment in
         lieu of any fraction of a share, as provided in Section 5.12.

                  (e) In the event that Merger Early Settlement is effected with
         respect to Forward Purchase Contracts underlying less than all the
         Equity Units or Stripped Units, as the case may be, evidenced by a
         Certificate, upon such Merger Early Settlement the Company (or the
         successor to the Company hereunder) shall execute and the Agent shall
         authenticate, execute on behalf of the Holder thereof and deliver to
         the Holder thereof, at the expense of the Company, a Certificate
         evidencing the Equity Units or Stripped Units, as the case may be, as
         to which Merger Early Settlement was not effected.

         Section 5.11    Charges and Taxes.

                                       53

<PAGE>

         The Company will pay all stock transfer and similar taxes attributable
to the initial issuance and delivery of the shares of Common Stock pursuant to
the Forward Purchase Contracts; provided, that the Company shall not be required
to pay any such tax or taxes which may be payable in respect of any exchange of
or substitution for a Certificate evidencing Equity Units or Stripped Units or
any issuance of a share of Common Stock in a name other than that of the
registered Holder of a Certificate surrendered in respect of the Equity Units
and Stripped Units evidenced thereby, other than in the name of the Agent, as
custodian for such Holder, and the Company shall not be required to issue or
deliver such share certificates or book-entry interest in Common Stock or
Certificates unless and until the Person or Persons requesting the transfer or
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

         Section 5.12    No Fractional Shares.

         No fractional shares or scrip representing fractional shares of Common
Stock shall be issued or delivered upon settlement on the Stock Purchase Date or
upon Early Settlement or Merger Early Settlement of any Forward Purchase
Contracts. If Certificates evidencing more than one Forward Purchase Contract
shall be surrendered for settlement at one time by the same Holder, the number
of full shares of Common Stock which shall be delivered upon settlement shall be
computed on the basis of the aggregate number of Forward Purchase Contracts
evidenced by the Certificates so surrendered. Instead of any fractional share of
Common Stock which would otherwise be deliverable upon settlement of any Forward
Purchase Contracts on the applicable Settlement Date or upon Early Settlement or
Merger Early Settlement, the Company, through the Agent, shall make a cash
payment in respect of such fractional share in an amount equal to the value of
such fractional share times the Applicable Market Value. The Company shall
provide the Agent from time to time with sufficient funds to permit the Agent to
make all cash payments required by this Section 5.12 in a timely manner.

         Section 5.13    Tax Treatment.

         The Company covenants and agrees and each Holder, by purchasing the
Equity Units agrees, (i) to treat a Holder's acquisition of the Equity Units as
the acquisition of the Note and Forward Purchase Contract constituting the
Equity Units, (ii) to treat a Holder's acquisition of the Stripped Units as the
acquisition of the Treasury Security and Forward Purchase Contract constituting
the Stripped Unit, (iii) to treat each Holder as the owner of the related Notes,
Treasury Consideration, Applicable Ownership Interest in the Treasury Portfolio
or Treasury Securities, as the case may be and (iv) to allocate the purchase
price of the Equity Unit between the Note and Forward Purchase Contract as $50
and $0, respectively.

                                   ARTICLE VI.
                                    REMEDIES

         Section 6.1     Unconditional Right of Holders to Purchase Common
         Stock.

                  (a) The Holder of any Equity Units or Stripped Units, as the
         case may be shall have the right, which is absolute and unconditional,
         subject to the right of the Company to defer payment thereof pursuant
         to Section 5.3, and to the forfeiture of any Deferred Contract

                                       54

<PAGE>

         Adjustment Payments upon Cash Settlement pursuant to Section 5.2(d),
         upon Early Settlement pursuant to Section 5.9(a), upon Merger Early
         Settlement pursuant to Section 5.10 or upon the occurrence of a
         Termination Event, to receive payment of each installment of the
         Contract Adjustment Payments, if any, with respect to the Purchase
         Contract constituting a part of such Equity Units or Stripped Units, as
         the case may be, on the respective Payment Date for such Equity Units
         or Stripped Units, as the case may be, and

                  (b) Subject to Section 5.6, the Holder of any Units shall have
         the right, which is absolute and unconditional, to purchase Common
         Stock pursuant to the Forward Purchase Contract constituting a part of
         such Units and to institute suit for the enforcement of any such right
         to purchase Common Stock, and such right shall not be impaired without
         the consent of such Holder.

         Section 6.2    Restoration of Rights and Remedies.

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

         Section 6.3    Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Certificates in Section 3.10(f), no
right or remedy herein conferred upon or reserved to the Holders is intended to
be exclusive of any other right or remedy, and every right and remedy shall, to
the extent permitted by law, be cumulative and in addition to every other right
and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         Section 6.4    Delay or Omission Not Waiver.

         No delay or omission of any Holder to exercise any right or remedy upon
a default shall impair any such right or remedy or constitute a waiver of any
such right. Every right and remedy given by this Article or by law to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by such Holders.

         Section 6.5    Undertaking For Costs.

         All parties to this Agreement agree, and each Holder of Equity Units or
Stripped Units, as the case may be, by its acceptance of such Equity Units or
Stripped Units, as the case may be, shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Agreement, or in any suit against the Agent for any
action taken, suffered or omitted by it as Agent, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable

                                       55

<PAGE>

costs, including reasonable attorneys' fees and expenses, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; provided that the provisions of
this Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Agent, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% of the Outstanding Units, or to
any suit instituted by any Holder for the enforcement of distributions on any
Notes or any Forward Purchase Contract on or after the respective Payment Date
therefor in respect of any Equity Units or Stripped Units, as the case may be,
held by such Holder, or for enforcement of the right to purchase shares of
Common Stock under the Forward Purchase Contract constituting part of any Equity
Units or Stripped Units, as the case may be, held by such Holder.

         Section 6.6    Waiver of Stay or Extension Laws.

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

                                  ARTICLE VII.
                                    THE AGENT

         Section 7.1    Certain Duties, Rights and Immunities.

                  (a) The Agent shall act as agent and attorney-in-fact for the
         Holders of the Equity Units and Stripped Units hereunder with such
         powers as are specifically vested in the Agent by the terms of this
         Agreement, the Pledge Agreement, the Remarketing Agreement, the Notes,
         the Equity Units and Stripped Units, and any documents evidencing them
         or related thereto (the "Transaction Documents"), together with such
         other powers as are reasonably incidental thereto. The Agent:

                         of any agreement by any party hereto beyond the
                         specific terms hereof;

                                (2) shall be entitled to conclusively rely upon

                         any thereof by telephone or facsimile) reasonably
                         believed by it to be genuine and correct and to have
                         been signed or sent by or on behalf of the proper
                         Person or Persons (without being required to determine
                         the correctness of any fact stated therein), (y) the
                         truth of the statements and the correctness of the
                         opinions expressed therein and (z) advice and
                         statements of legal counsel and other experts selected

                  Agent;

                           (3) shall in all cases be fully protected in acting,
                  or in refraining from acting, hereunder or under any
                  Transaction Documents in accordance with instructions given by
                  the Company or the Holders in accordance herewith or with the
                  Transaction Documents;

                           (4) shall not be responsible for any recitals
                  contained in any Transaction Document, or in any certificate
                  or other document referred to or provided for in, or received
                  by it under, any Transaction Document or the Equity Units or
                  Stripped Units, or for the value, validity, effectiveness,
                  genuineness, enforceability or sufficiency of any Transaction
                  Document (other than as against the Agent) or the Equity Units
                  or Stripped Units or any other document referred to or
                  provided for herein or therein or for any failure by the
                  Company, any Holder or any other Person (except the Agent) to
                  perform any of its obligations hereunder or thereunder or for
                  the perfection, priority or, except as expressly required
                  hereby, existence, validity, perfection or maintenance of any
                  security interest created under the Pledge Agreement, or for
                  the use or application by the Company of the proceeds in
                  respect of the Forward Purchase Contracts;

                           (5) shall not be required to initiate or conduct any
                  litigation or collection proceedings hereunder;

                           (6) shall not be responsible for any action taken or
                  omitted to be taken by it hereunder or under the Transaction
                  Documents or any other document or instrument referred to or
                  provided for herein or therein or in connection herewith or
                  therewith, except for its own negligence, bad faith or willful
                  misconduct; and

                           (7) shall not be required to advise any party as to
                  selling or retaining, or taking or refraining from taking any
                  action with respect to, the Equity Units or Stripped Units or
                  other rights under any Transaction Document.

         (b) No provision of any Transaction Document shall be construed to
relieve the Agent from liability for its own negligent action, its own negligent
failure to act, its own bad faith, or its own willful misconduct, except that:

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

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

                  (3) in no event shall the Agent be required to expend or risk
         its own funds or otherwise incur any financial liability in the
         performance of any of

                                       57

<PAGE>

         its duties hereunder.

                  (c) In no event shall the Agent or its officers, employees or
         agents be liable for any special, indirect, individual, punitive or
         consequential loss or damages, lost profits or loss of business,
         arising in connection with any Transaction Document, whether or not the
         likelihood of such loss or damage was known to the Agent, and
         regardless of the form of action.

                  (d) Whether or not therein expressly so provided, every
         provision of every Transaction Document relating to the conduct or
         affecting the liability of or affording protection to the Agent shall
         be subject to the provisions of this Section.

                  (e) The Agent is authorized to execute and deliver the Pledge
         Agreement and the Remarketing Agreement and any supplement thereto in
         its capacity as Agent. The Agent shall be entitled to all of the
         rights, privileges, immunities and indemnities contained in this
         Agreement with respect to any duties of the Agent under, or actions
         taken, omitted to be taken or suffered by the Agent pursuant to the
         Pledge Agreement.

                  (f) The Agent shall have no liability whatsoever for the
         action or inaction of any Clearing Agency or any book-entry system
         thereof. In no event shall any Clearing Agency or any book-entry system
         thereof be deemed an agent or subcustodian of the Agent.

                  (g) The Agent shall not be responsible or liable for any
         failure or delay in the performance of its obligations under any
         Transaction Document arising out of or caused, directly or indirectly,
         by circumstances beyond its reasonable control, including, without
         limitation, acts of God; acts of terrorism; earthquakes; fires; floods;
         wars; civil or military disturbances; sabotage; epidemics; riots;
         interruptions, loss or malfunctions of utilities, computer (hardware or
         software) or communications service; accidents; labor disputes; acts of
         civil or military authority; governmental actions; or inability to
         obtain labor, material, equipment or transportation.

its obligations hereunder or under one or more Forward Purchase Contracts of
which a Responsible Officer of the Agent has actual knowledge, the Agent shall
transmit by mail to the Company and the Holders of Equity Units and Stripped
Units, as their names and addresses appear in the Register, notice of such

         Section 7.5    May Hold Equity Units and Stripped Units and Other
Dealings.

         Any Registrar or any other agent of the Company, or the Agent and its
Affiliates, in their individual or any other capacity, may become the owner or
pledgee of Equity Units or Stripped Units, as the case may be, and may otherwise
deal with the Company, the Collateral Agent or any other Person with the same
rights it would have if it were not Registrar or such other agent, or the Agent.
The Agent and its Affiliates may (without having to account therefor to the
Company or any Holder of Equity Units or Stripped Units or holder of Separate
Notes) accept deposits from, lend money to, make other investments in and
generally engage in any kind of banking, trust or other business with the
Company, any Holder of Equity Units or Stripped Units and any holder of Separate
Notes (and any of their respective subsidiaries or Affiliates) as if it were not
acting as the Agent and the Agent and its Affiliates may accept fees and other

         The Company agrees:

                  (a) to pay to the Agent from time to time compensation for all
         services rendered by it hereunder or under the Transaction Documents as
         shall be agreed in writing between the Company and the Agent;

                  (b) to reimburse the Agent upon its request for all reasonable
         expenses, disbursements and advances incurred or made by the Agent in
         accordance with any provision of this Agreement or the other
         Transaction Documents (including the reasonable compensation and the
         reasonable expenses and disbursements of its agents and counsel),
         except any such expense, disbursement or advance as may be attributable
         to its negligence, willful misconduct or bad faith; and

                  (c) to indemnify the Agent for, and to hold it harmless
         against, any loss, liability or reasonable out-of-pocket expense
         incurred without gross negligence, willful misconduct or bad faith on
         its part, arising out of or in connection with the acceptance or
         administration of its duties under the other Transaction Documents,
         including the costs and expenses (including reasonable fees and
         expenses of counsel) of defending itself against any claim, whether
         asserted by the Company, a Holder or any other Person, or liability in
         connection

         with the exercise or performance of any of its powers or duties under
         the Transaction Documents. The Agent shall promptly notify the Company
         of any third party claim which may give rise to the indemnity hereunder
         and give the Company the opportunity to participate in the defense of
         such claim with counsel reasonably satisfactory to the indemnified
         party, and no such claim shall be settled without the written consent
         of the Company, which consent shall not be unreasonably withheld,
         provided that any failure to give any such notice shall not affect the
         obligation of the Company under this Section. The provisions of this
         Section 7.7 shall survive the termination of any and all Transaction
         Documents, the satisfaction or discharge of the Equity Units or
         Stripped Units and/ or the Separate Notes or the resignation or removal
         of the Agent.

         Section 7.8    Corporate Agent Required; Eligibility.

         There shall at all times be an Agent hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having (or being a member of a bank
holding company having) a combined capital and surplus of at least $500,000,000,
subject to supervision or examination by federal or state authority and having
(or being a member of a bank holding company having) a Corporate Trust Office in
the Borough of Manhattan, the City of New York, if there be such a corporation,
qualified and eligible under this Article and willing to act on reasonable
terms. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Agent shall cease to be eligible in accordance with the provisions
of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

         Section 7.9    Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Agent and no appointment
         of a successor Agent pursuant to this Article shall become effective
         until the acceptance of appointment by the successor Agent in
         accordance with the applicable requirements of Section 7.10.

                  (b) The Agent may resign at any time by giving written notice
         thereof to the Company 60 days prior to the effective date of such
         resignation. If the instrument of acceptance by a successor Agent
         required by Section 7.10 shall not have been delivered to the Agent
         within 30 days after the giving of such notice of resignation, the
         resigning Agent may petition, at the expense of the Company, any court
         of competent jurisdiction for the appointment of a successor Agent.

                  (c) The Agent may be removed at any time by Act of the Holders
         of a majority in number of the Outstanding Units upon delivery of a
         written notice to the Agent and the Company. If the instrument of
         acceptance by a successor Agent required by Section 7.10 shall not have
         been delivered to the Agent within 30 days after the giving of such
         notice of removal, the Agent to be removed may petition, at the expense
         of the Company, any court of competent jurisdiction for the appointment
         of a successor Agent.

                  (d) If at any time:

                                    (1) the Agent has a "conflicting interest"
                           (as defined in Section 310(b) of the TIA) and fails
                           to eliminate the conflicting interest or resign
                           pursuant to Section 310(b) of the TIA upon written
                           request therefor by the Company or by any Holder who
                           has been a bona fide Holder of a Unit for at least
                           six months, as if this Agreement were an indenture
                           qualified under the TIA, as if the Equity Units or
                           Stripped Units were in default and as if such default
                           had not been cured or waived within the applicable
                           period under Section 310(b) of the TIA; or

                                    (2) the Agent shall cease to be eligible
                           under Section 7.8 and shall fail to resign after
                           written request therefor by the Company or by any
                           such Holder; or

                                    (3) the Agent shall become incapable of
                           acting or shall be adjudged a bankrupt or insolvent
                           or a receiver of the Agent or of its property shall
                           be appointed or any public officer shall take charge
                           or control of the Agent or of its property or affairs
                           for the purpose of rehabilitation, conservation or
                           liquidation;

then, in any such case, (x) the Company by a Board Resolution may remove the
Agent, or (y) any Holder who has been a bona fide Holder of Equity Units or
Stripped Equity Units for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Agent and the appointment of a successor Agent.

                  (e) If the Agent shall resign, be removed or become incapable
         of acting, or if a vacancy shall occur in the office of Agent for any
         cause, the Company, by a Board Resolution, shall promptly appoint a
         successor Agent and shall comply with the applicable requirements of
         Section 7.10. If no successor Agent shall have been so appointed by the
         Company and accepted appointment in the manner required by Section
         7.10, any Holder who has been a bona fide Holder of Equity Units or
         Stripped Equity Units for at least six months may, on behalf of himself
         and all others similarly situated, petition any court of competent
         jurisdiction for the appointment of a successor Agent.

                  (f) The Company shall give, or shall cause such successor
         Agent to give, notice of each resignation and each removal of the Agent
         and each appointment of a successor Agent by mailing written notice of
         such event by first-class mail, postage prepaid, to all Holders as
         their names and addresses appear in the applicable Register. Each
         notice shall include the name of the successor Agent and the address of
         its Corporate Trust Office.

         Section 7.10    Acceptance of Appointment By Successor.

                  (a) In case of the appointment hereunder of a successor Agent,
         every such successor Agent so appointed shall execute, acknowledge and
         deliver to the Company and to the retiring Agent an instrument
         accepting such appointment, and thereupon the resignation or removal of
         the retiring Agent shall become effective and such successor Agent,
         without any further act, deed or conveyance, shall become vested with
         all the rights,

                                       62

<PAGE>

         powers, agencies, trusts and duties of the retiring Agent; but, on the
         request of the Company or the successor Agent, such retiring Agent
         shall, upon payment of its charges, execute and deliver an instrument
         transferring to such successor Agent all the rights, powers, agencies,
         trusts and duties of the retiring Agent and duly assign, transfer and
         deliver to such successor Agent all property and money held by such
         retiring Agent hereunder.

                  (b) Upon request of any such successor Agent, the Company
         shall execute any and all instruments for more fully and certainly
         vesting in and confirming to such successor Agent all such rights,
         powers, agencies, trusts and duties referred to in paragraph (a) of
         this Section.

                  (c) No successor Agent shall accept its appointment unless at
         the time of such acceptance such successor Agent shall be qualified and
         eligible under this Article.

         Section 7.11   Merger, Conversion, Consolidation or Succession to
Business.

         Any corporation into which the Agent may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Agent shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Agent, shall be the successor of the Agent hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Certificates shall have been
authenticated and executed on behalf of the Holders, but not delivered, by the
Agent then in office, any successor by merger, conversion or consolidation to
such Agent shall adopt such authentication and execution and deliver the
Certificates so authenticated and executed with the same effect as if such
successor Agent had itself authenticated and executed such Equity Units and
Stripped Units.

         Section 7.12   Preservation of Information; Communications to Holders.

                  (a) The Agent shall preserve, in as current a form as is
         reasonably practicable, the names and addresses of Holders received by
         the Agent in its capacity as Registrar.

                  (b) If three or more Holders (herein referred to as
         "Applicants") apply in writing to the Agent, and furnish to the Agent
         reasonable proof that each such applicant has owned Equity Units or
         Stripped Units, as the case may be, for a period of at least six months
         preceding the date of such application, and such application states
         that the Applicants desire to communicate with other Holders with
         respect to their rights under this Agreement or under the Equity Units
         or Stripped Units, as the case may be, and is accompanied by a copy of
         the form of proxy or other communication which such Applicants propose
         to transmit, then the Agent shall mail to all the Holders copies of the
         form of proxy or other communication which is specified in such
         request, with reasonable promptness after a tender to the Agent of the
         materials to be mailed and of payment, or provision, in the absence of
         bad faith, satisfactory to the Agent for the payment, of the reasonable
         expenses of such mailing.

         Section 7.13   Failure to Act.

                                       63

<PAGE>

         In the event of any ambiguity in the provisions of any Transaction
Document or any dispute between or conflicting claims by or among the parties
hereto or any other Person, the Agent shall be entitled, after prompt notice to
the Company and the Holders of Equity Units and Stripped Units, at its sole
option, to refuse to comply with any and all such claims, demands or
instructions so long as such dispute or conflict shall continue, and the Agent
shall not be or become liable in any way to any of the parties hereto for its
failure or refusal to comply with such conflicting claims, demands or
instructions. The Agent shall be entitled to refuse to act until either (i) such
conflicting or adverse claims or demands shall have been finally determined by a
court of competent jurisdiction or settled by agreement between the conflicting
parties as evidenced in a writing, reasonably satisfactory to the Agent, or (ii)
the Agent shall have received security or an indemnity reasonably satisfactory
to the Agent sufficient to save the Agent harmless from and against any and all
loss, liability or reasonable out-of-pocket expense which the Agent may incur by
reason of its acting without bad faith, willful misconduct or gross negligence.
The Agent may in addition elect to commence an interpleader action or seek other
judicial relief or orders as the Agent may deem necessary. Notwithstanding
anything contained herein to the contrary, the Agent shall not be required to
take any action that is in its opinion contrary to law or to the terms of any
Transaction Document, or which would in its opinion subject it or any of its
officers, employees or directors to liability.

         Section 7.14      No Obligations of Agent.

         Except to the extent otherwise provided in this Agreement, the Agent
assumes no obligation and shall not be subject to any liability under this
Agreement, the Pledge Agreement or any Forward Purchase Contract in respect of
the obligations of the Holder of any Equity Units or Stripped Units thereunder.
The Company agrees, and each Holder of a Certificate, by such Holder's
acceptance thereof, shall be deemed to have agreed, that the Agent's execution
of the Certificates on behalf of the Holders shall be solely as agent and
attorney-in-fact for the Holders, and that the Agent shall have no obligation to
perform such Forward Purchase Contracts on behalf of the Holders, except to the
extent expressly provided in Article V. Anything contained in this Agreement to
the contrary notwithstanding, in no event shall the Agent or its officers,
employees or agents be liable for indirect, special, punitive, or consequential
loss or damage of any kind whatsoever, including, but not limited to, lost
profits, whether or not the likelihood of such loss or damage was known to the
Agent and regardless of the form of action.

         Section 7.15      Tax Compliance.

                  (a) The Agent, on its own behalf and on behalf of the Company,
         will comply with all applicable certification, information reporting
         and withholding (including "backup" withholding) requirements imposed
         on it as a paying agent by applicable tax laws, regulations or
         administrative practice with respect to any payments made with respect
         to the Equity Units and Stripped Units. Such compliance shall include,
         without limitation, the preparation and timely filing of required
         returns and the timely payment of all amounts required to be withheld
         to the appropriate taxing authority or its designated agent.

                  (b)The Agent shall comply with any reasonable written
         direction timely received from the Company with respect to the
         application of such requirements to particular

                                       64

<PAGE>

         payments to Holders or in other particular circumstances, and may for
         purposes of this Agreement rely on any such direction in accordance
         with Section 7.1(a)(2).

                  (c) The Agent shall maintain all appropriate records
         documenting compliance with such requirements, and shall make such
         records available, on written request, to the Company or its authorized
         representative within a reasonable period of time after receipt of such
         request.

computed on the basis of a 360-day year of twelve 30-day months, subject to
deferral at the option of the Company as provided in the Forward Purchase
Contract Agreement and more fully described on the reverse hereof (provided that
if any date on which a Contract Adjustment Payment is to be made on the Forward
Purchase Contracts is not a Business Day, then payment of such Contract
Adjustment Payment payable on such date will be made on the next succeeding day
which is a Business Day, and no interest or payment will be paid in respect of
such delay, except that if such next succeeding Business Day is in the next
succeeding calendar year, then such payment will be made on the immediately
preceding Business Day). Such Contract Adjustment Payments shall be payable to
the Person in whose name this Equity Units Certificate (or a Predecessor Equity
Units Certificate) is registered at the close of business on the Record Date for
such Payment Date.

     Contract Adjustment Payments will be payable at the Office of the Agent in

address of the Person entitled thereto as such address appears on the Equity
Units Register or by wire transfer to the account designated to the Agent by a

Agent by manual signature, this Equity Units Certificate shall not be entitled
to any benefit under the Pledge Agreement or the Forward Purchase Contract
Agreement or be valid or obligatory for any purpose.

                  (Form of Reverse of Equity Units Certificate)

     Each Forward Purchase Contract evidenced hereby is governed by a Forward
Purchase Contract Agreement, dated as of June 11, 2002 (as may be supplemented
from time to time, the "Forward Purchase Contract Agreement"), between the
Company and The Bank of New York, as Forward Purchase Contract Agent (including
its successors thereunder, herein called the "Agent"), to which Forward 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 Equity Units Certificates are, and are to be,
executed and delivered.

     Each Forward Purchase Contract evidenced hereby obligates the Holder of
this Equity Units Certificate to purchase, and the Company to sell, on the Stock
Purchase Date at a price equal to $50 (the "Purchase Price"), a number of shares
of Common Stock of the Company equal to the Settlement Rate, unless, on or prior
to the Stock Purchase Date, there shall have occurred a Termination Event or an
Early Settlement, Merger Early Settlement or Cash Settlement with respect to the
Units of which such Forward Purchase Contract is a part. The "Settlement Rate"
is equal to (a) if the Applicable Market Value (as defined below) is greater
than or equal to $49.08 (the "Threshold Appreciation Price"), 1.0187 shares of
Common Stock per Forward Purchase Contract, (b) if the Applicable Market Value
is less than the Threshold Appreciation Price but is greater than $40.90, the
number of shares of Common Stock per Forward Purchase Contract equal to the
Stated Amount of the related Equity Units divided by the Applicable Market Value
and (c) if the Applicable Market Value is less than or equal to $40.90, 1.2225
shares of Common Stock per Forward Purchase Contract, in each case subject to
adjustment as provided in the Forward Purchase Contract Agreement. No fractional
shares of Common Stock will be issued upon settlement of Forward Purchase
Contracts, as provided in the Forward Purchase Contract Agreement.

     The "Applicable Market Value" means the average of the Closing Price per
share of Common Stock on each of the 20 consecutive Trading Days ending on the
third Trading Day immediately preceding the Stock Purchase Date.

     The "Closing Price" of the Common Stock on any date of determination means
the closing sale price (or, if no closing price is reported, the last reported
sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on
such date or, if the Common Stock is not listed for trading on the NYSE on any
such date, as reported in the composite transactions for the principal United
States securities exchange on which the Common Stock is so listed, or if the
Common Stock is not so listed on a United States national or regional securities
exchange, as reported by The NASDAQ Stock Market, or, 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, if such bid price is not available, the market value of the
Common Stock on such date as determined by a nationally recognized independent
investment banking firm 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

                                      A-7

<PAGE>

exchange or association or over-the-counter market that is the primary market
for the trading of the Common Stock.

     Each Forward Purchase Contract evidenced hereby may be settled prior to the
Stock Purchase Date through Early Settlement or Merger Early Settlement, and may
be settled on the Stock Purchase Date through Cash Settlement, all in accordance
with the terms of the Forward Purchase Contract Agreement.

     In accordance with the terms of the Forward Purchase Contract Agreement,
the Holder of this Equity Units Certificate shall pay the Purchase Price for the
shares of Common Stock purchased pursuant to each Forward Purchase Contract
evidenced hereby (i) by effecting a Cash Settlement, Early Settlement or Merger
Early Settlement, (ii) by application of payments received in respect of the
Pledged Treasury Consideration acquired from the proceeds of a remarketing of
the related Pledged Notes underlying the Equity Units represented by this Equity
Units Certificate, (iii) if the Holder has elected not to participate in the
remarketing, by application of payments received in respect of the Pledged
Treasury Consideration deposited by such Holder in respect of such Forward
Purchase Contract, or (iv) if a Tax Event Redemption has occurred prior to the
successful remarketing of the Notes, by application of payments received in
respect of the Pledged Applicable Ownership Interest in the Treasury Portfolio
purchased by the Collateral Agent on behalf of the Holder of this Equity Units
Certificate. If, as provided in the Forward Purchase Contract Agreement, upon
the occurrence of the Last Failed Remarketing, the Collateral Agent, for the
benefit of the Company, exercises its rights as a secured creditor with respect
to the Pledged Notes related to this Equity Units Certificate, any accrued and
unpaid interest on such Pledged Notes will become payable by the Company to the
Holder of this Equity Units Certificate in the manner provided for in the
Forward Purchase Contract Agreement.

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

     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
Notes, but only to the extent instructed by the Holders as described below. Upon
receipt of notice of any meeting at which holders of Notes are entitled to vote
or upon the solicitation of consents, waivers or proxies of holders of Notes,
the Agent shall, as soon as practicable thereafter, mail to the Holders of
Equity Units a notice (a) containing such information as is contained in the
notice or solicitation, (b) stating that each such 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 Notes entitled to vote) shall be
entitled to instruct the Agent as to the exercise of the voting rights
pertaining to the Pledged Notes constituting a part of such Holder's Equity
Units and (c) stating the manner in which such instructions may be given. Upon
the written request of the Holders of Equity Units 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 number
of Pledged Notes as to which any particular voting instructions are received. In
the absence of specific instructions from the Holder of an Equity Unit, the
Agent shall abstain from voting the Pledged Note evidenced by such Equity Units.

                                      A-8

<PAGE>

     The Equity Units Certificates are issuable only in registered form and only
in denominations of a single Equity Unit and any integral multiple thereof. The
transfer of any Equity Units Certificate will be registered and Equity Units
Certificates may be exchanged as provided in the Forward Purchase Contract
Agreement. The Equity Units Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the
Forward 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. The Holder of an Equity Units may
substitute for the Pledged Notes securing its obligations under the related
Forward Purchase Contract Treasury Securities in accordance with the terms of
the Forward Purchase Contract Agreement and the Pledge Agreement. From and after
such Collateral Substitution, the Units for which such Pledged Treasury
Securities secure the Holder's obligation under the Forward Purchase Contract
shall be referred to as a "Stripped Unit." A Holder that elects to substitute a
Treasury Security for Pledged Notes thereby creating Stripped Units, shall be
responsible for any fees or expenses payable in connection therewith. Except as
provided in the Forward Purchase Contract Agreement, for so long as the Forward
Purchase Contract underlying an Equity Unit remains in effect, such Equity Unit
shall not be separable into its constituent parts, and the rights and
obligations of the Holder of such Equity Unit in respect of the Pledged Note and
Forward Purchase Contract constituting such Equity Unit may be transferred and
exchanged only as an Equity Unit.

     A Holder of Stripped Units may reestablish Equity Units by delivering to
the Collateral Agent Notes in exchange for the release of the Pledged Treasury
Securities in accordance with the terms of the Forward Purchase Contract
Agreement and the Pledge Agreement.

     Subject to the next succeeding paragraph, the Company shall pay on each
Payment Date, the Contract Adjustment Payments, if any, payable in respect of
each Forward Purchase Contract to the Person in whose name the Equity Units
Certificate evidencing such Forward Purchase Contract is registered at the close
of business on the Record Date for such Payment Date. Contract Adjustment
Payments, if any, 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 Equity Units
Register or by wire transfer to the account designated by such Person in writing
at least five Business Days prior to the applicable Payment Date.

     The Company shall have the right, at any time prior to the Stock Purchase
Date, to defer the payment of any or all of the Contract Adjustment Payments
otherwise payable on any Payment Date, but only if the Company shall give the
Holders and the Agent written notice of its election to defer Contract
Adjustment Payments as provided in the Forward Purchase Contract Agreement. Any
Contract Adjustment Payments so deferred shall, to the extent permitted by law,
bear additional Contract Adjustment Payments thereon at the rate of 5.75% per
year (computed on the basis of a 360-day year of twelve 30-day months),
compounding on each succeeding Payment Date, until paid in full (such deferred
installments of Contract Adjustment Payments, if any, together with the
additional Contract Adjustment Payments, if any, accrued thereon, are referred
to herein as the "Deferred Contract Adjustment Payments"). Deferred Contract
Adjustment Payments, if any, shall be due on the next succeeding Payment Date
except to the extent that payment is deferred pursuant to the Forward Purchase
Contract Agreement. No Contract Adjustment Payments may be deferred to a date
that is after the Stock Purchase Date and no such

                                      A-9

<PAGE>

deferral period may end other than on a Payment Date.

     In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Forward Purchase Contracts until a Payment Date prior
to the Stock Purchase Date, then all Deferred Contract Adjustment Payments, if
any, shall be payable to the registered Holders as of the close of business on
the Record Date immediately preceding such Payment Date.

     In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, then, until the Deferred Contract Adjustment
Payments have been paid, the Company shall not declare or pay dividends on, make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its Common Stock other than (i)
purchases, redemptions or acquisitions of shares of Common Stock in connection
with any employment contract, benefit plan or other similar arrangement with or
for the benefit of employees, officers or directors or a stock purchase or
dividend reinvestment plan, or the satisfaction by the Company of its
obligations pursuant to any contract or security outstanding on the date the
Company exercises its rights to defer the Contract Adjustment Payments; (ii) as
a result of a reclassification of the Company's Capital Stock or the exchange or
conversion of one class or series of for another class or series of the
Company's Capital Stock; (iii) the purchase of fractional interests in shares of
any series of the Company's Common Stock pursuant to the conversion or exchange
provisions of such Common Stock or the security being converted or exchanged;
(iv) dividends or distributions in any series of the Company's Common Stock (or
rights to acquire Common Stock) or repurchases, acquisitions or redemptions of
Common Stock in connection with the issuance or exchange of any series of Common
Stock (or securities convertible into or exchangeable for shares of the
Company's Common Stock); or (v) redemptions, exchanges or repurchases of any
rights outstanding under a shareholder rights plan or the declaration or payment
thereunder of a dividend or distribution of or with respect to rights in the
future.

     The Forward Purchase Contracts and all obligations and rights of the
Company and the Holders thereunder, including, without limitation, the rights
and obligations of the Holders to receive and the obligation of the Company to
pay Contract Adjustment Payments, if any, or any Deferred Contract Adjustment
Payments, and the rights of the Holders to purchase Common Stock, 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 Stock
Purchase 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 to the Holders, at their addresses as they appear in the Equity Units
Register. Upon and after the occurrence of a Termination Event, the Collateral
Agent shall release the Pledged Notes, Pledged Treasury Consideration or Pledged
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
from the Pledge in accordance with the provisions of the Pledge Agreement.

     Upon registration of transfer of this Equity Units 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
Forward Purchase Contract Agreement), by the terms of the Forward Purchase
Contract Agreement and the Forward Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Forward Purchase
Contracts evidenced

                                      A-10

<PAGE>

Holder, by its acceptance hereof, likewise covenants and agrees, to be bound by
the provisions of this paragraph.

     The Holder of this Equity Units Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Forward Purchase
Contracts forming part of the Equity Units evidenced hereby on its behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Forward 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 of the Forward Purchase
Contracts, covenants and agrees to perform such Holder's obligations under such
Forward Purchase Contracts, consents to the provisions of the Forward Purchase
Contract Agreement, irrevocably authorizes the Agent to enter into and perform
the Pledge Agreement on such Holder's behalf as attorney-in-fact, and consents
to and agrees to be bound by the Pledge of the Notes or the appropriate Treasury
Consideration or Applicable Ownership Interest in the Treasury Portfolio, as the
case may be, underlying this Equity Units Certificate pursuant to the Pledge
Agreement, provided, that upon a Termination Event, the rights of the Holder of
such Units under the Forward Purchase Contract may be enforced without regard to
any other rights or obligations. The Holder further covenants and agrees, that,
to the extent and in the manner provided in the Forward Purchase Contract
Agreement and the Pledge Agreement, but subject to the terms thereof, payments
in respect of the Pledged Notes, Pledged Treasury Consideration or Pledged
Applicable Ownership Interest in the Treasury Portfolio, as the case may be, to
be paid upon settlement of such Holder's obligations to purchase Common Stock
under the Forward Purchase Contract, shall be paid on the Stock Purchase Date by
the Collateral Agent to the Company in satisfaction of such Holder's obligations
under such Forward Purchase Contract and such Holder shall acquire no right,
title or interest in such payments.

     The Company and each Holder of an Equity Unit, and each Beneficial Owner
thereof, by its acceptance thereof or of its interest therein, further agrees to
treat (i) the purchase of Equity Units as the purchase of a unit consisting of
the Forward Purchase Contract and the Note and to allocate the purchase price of
the Equity Unit between the Note and the Forward Purchase Contract as $50 and
$0, respectively, and (ii) the holder as the owner of the applicable interest in
the Collateral Account, including the related Notes, Treasury Consideration or
Applicable Ownership Interest in the Treasury Portfolio, as the case may be.

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

     The Forward Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York, without regard
to its principles of conflicts of laws.

     The Company, the Agent and any agent of the Company or the Agent may treat
the Person in whose name this Equity Units Certificate is registered as the
owner of the Equity Units evidenced hereby for the purpose of receiving
quarterly payments on the Notes, the Treasury Consideration or the Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, receiving
payments of Contract Adjustment Payments, if any, and any Deferred Contract
Adjustment Payments, performance of the Forward Purchase Contracts and for all
other purposes

whatsoever (subject to the Record Date provisions hereof), 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 Forward 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 Forward Purchase Contract Agreement is available for
inspection by any Holder at the Corporate Trust Office.

prior to the Stock Purchase Date there shall have occurred a Termination Event
or an Early Settlement, Merger Early Settlement or Cash Settlement with respect

(the "Contract Adjustment Payments") equal to 3.50% per year of the Stated
Amount, computed on the basis of a 360-day year of twelve 30-day months, subject
to deferral at the option of the Company as provided in the Forward Purchase
Contract Agreement and more fully described on the reverse hereof (provided that
if any date on which Contract Adjustment Payments are to be made on the Forward
Purchase Contracts is not a Business Day, then payment of the Contract
Adjustment Payments payable on that date will be made on the next succeeding day
which is a Business Day, and no interest or payment will be paid in respect of
the delay, except that if such next succeeding Business Day is in the next
succeeding calendar year, such payment will be made on the immediately preceding
Business Day). Such Contract Adjustment Payments shall be payable to the Person
in whose name this Stripped Units Certificate (or a Predecessor Stripped Units
Certificate) is registered at the close of business on the Record Date for such
Payment Date.

     Contract Adjustment Payments, if any, 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

such Person in writing at least five Business Days prior to the applicable
Payment Date.

                     (Reverse of Stripped Units Certificate)

     Each Forward Purchase Contract evidenced hereby is governed by a Forward
Purchase Contract Agreement, dated as of June 11, 2002 (as may be supplemented
from time to time, the "Forward Purchase Contract Agreement"), between the
Company and The Bank of New York, as Forward Purchase Contract Agent (including
its successors thereunder, herein called the "Agent"), to which Forward 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 Stripped Units Certificates are, and are to be,
executed and delivered.

     Each Forward Purchase Contract evidenced hereby obligates the Holder of
this Stripped Units Certificate to purchase, and the Company to sell, on the
Stock Purchase Date at a price equal to $50 (the "Purchase Price"), a number of
shares of Common Stock of the Company equal to the Settlement Rate, unless, on
or prior to the Stock Purchase Date, there shall have occurred a Termination
Event or an Early Settlement or Merger Early Settlement with respect to the
Stripped Units of which such Forward Purchase Contract is a part. The
"Settlement Rate" is equal to (a) if the Applicable Market Value (as defined
below) is greater than or equal to $49.08 (the "Threshold Appreciation Price"),
1.0187 shares of Common Stock per Forward Purchase Contract, (b) if the
Applicable Market Value is less than the Threshold Appreciation Price but is
greater than $40.90, the number of shares of Common Stock per Forward Purchase
Contract equal to the Stated Amount of the related Stripped Units divided by the
Applicable Market Value and (c) if the Applicable Market Value is less than or
equal $40.90, 1.2225 shares of Common Stock per Forward Purchase Contract, in
each case subject to adjustment as provided in the Forward Purchase Contract
Agreement. No fractional shares of Common Stock will be issued upon settlement
of Forward Purchase Contracts, as provided in the Forward Purchase Contract
Agreement.

     The "Applicable Market Value" means the average of the Closing Price per
share of Common Stock on each of the 20 consecutive Trading Days ending on the
third Trading Day immediately preceding the Stock Purchase Date.

     The "Closing Price" of the Common Stock on any date of determination means
the closing sale price (or, if no closing price is reported, the last reported
sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on
such date or, if the Common Stock is not listed for trading on the NYSE on any
such date, as reported in the composite transactions for the principal United
States securities exchange on which the Common Stock is so listed, or if the
Common Stock is not so listed on a United States national or regional securities
exchange, as reported by The NASDAQ Stock Market, or, 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, if such bid price is not available, the market value of the
Common Stock on such date as determined by a nationally recognized independent
investment banking firm 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

                                       B-5

<PAGE>

exchange or association or over-the-counter market that is the primary market
for the trading of the Common Stock.

     Each Forward Purchase Contract evidenced hereby may be settled prior to the
Stock Purchase Date through Early Settlement or Merger Early Settlement, and may
be settled on the Stock Purchase Date through Cash Settlement, all in accordance
with the terms of the Forward Purchase Contract Agreement.

     In accordance with the terms of the Forward Purchase Contract Agreement,
the Holder of this Stripped Units Certificate shall pay the Purchase Price for
the shares of Common Stock purchased pursuant to each Forward Purchase Contract
evidenced hereby (i) by effecting an Early Settlement, Merger Early Settlement
or Cash Settlement or (ii) by application of payments received in respect of the
Pledged Treasury Securities underlying the Stripped Units represented by this
Stripped Units Certificate.

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

     The Stripped Units Certificates are issuable only in registered form and
only in denominations of a single Stripped Units and any integral multiple
thereof. The transfer of any Stripped Units Certificate will be registered and
Stripped Units Certificates may be exchanged as provided in the Forward Purchase
Contract Agreement. The Stripped Units Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Forward 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. The Holder of a Stripped
Unit may substitute for the Pledged Treasury Securities securing its obligations
under the related Forward Purchase Contract Notes in accordance with the terms
of the Forward Purchase Contract Agreement and the Pledge Agreement. From and
after such substitution, the Units for which such Pledged Notes secure the
Holder's obligation under the Forward Purchase Contract shall be referred to as
an "Equity Unit." A Holder that elects to substitute Notes for Pledged Treasury
Securities, thereby reestablishing Equity Units, shall be responsible for any
fees or expenses payable in connection therewith. Except as provided in the
Forward Purchase Contract Agreement, for so long as the Forward Purchase
Contract underlying a Stripped Unit remains in effect, such Stripped Units shall
not be separable into its constituent parts, and the rights and obligations of
the Holder of such Stripped Units in respect of the Pledged Treasury Security
and the Forward Purchase Contract constituting such Stripped Units may be
transferred and exchanged only as a Stripped Unit.

     Subject to the next succeeding paragraph, the Company shall pay on each
Payment Date, the Contract Adjustment Payments, if any, payable in respect of
each Forward Purchase Contract to the Person in whose name the Stripped Units
Certificate evidencing such Forward Purchase Contract is registered at the close
of business on the Record Date for such Payment Date. Contract Adjustment
Payments, if any, 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

                                       B-6

<PAGE>

such address as it appears on the Stripped Units Register or by wire transfer to
the account designated by such Person in writing at least five Business Days
prior to the applicable Payment Date.

     The Company shall have the right, at any time prior to the Stock Purchase
Date, to defer the payment of any or all of the Contract Adjustment Payments
otherwise payable on any Payment Date, but only if the Company shall give the
Holders and the Agent written notice of its election to defer Contract
Adjustment Payments as provided in the Forward Purchase Contract Agreement. Any
Contract Adjustment Payments so deferred shall, to the extent permitted by law,
bear additional Contract Adjustment Payments thereon at the rate of 5.75% per
year (computed on the basis of a 360-day year of twelve 30-day months),
compounding on each succeeding Payment Date, until paid in full (such deferred
installments of Contract Adjustment Payments, if any, together with the
additional Contract Adjustment Payments, if any, accrued thereon, are referred
to herein as the "Deferred Contract Adjustment Payments"). Deferred Contract
Adjustment Payments, if any, shall be due on the next succeeding Payment Date
except to the extent that payment is deferred pursuant to the Forward Purchase
Contract Agreement. No Contract Adjustment Payments may be deferred to a date
that is after the Stock Purchase Date and no such deferral period may end other
than on a Payment Date.

     In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Forward Purchase Contracts until a Payment Date prior
to the Stock Purchase Date, then all Deferred Contract Adjustment Payments, if
any, shall be payable to the registered Holders as of the close of business on
the Record Date immediately preceding such Payment Date.

     In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, then, until the Deferred Contract Adjustment
Payments have been paid, the Company shall not declare or pay dividends on, make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its Common Stock other than (i)
purchases, redemptions or acquisitions of shares of Common Stock in connection
with any employment contract, benefit plan or other similar arrangement with or
for the benefit of employees, officers or directors or a stock purchase or
dividend reinvestment plan, or the satisfaction by the Company of its
obligations pursuant to any contract or security outstanding on the date the
Company exercises its rights to defer the Contract Adjustment Payments; (ii) as
a result of a reclassification of the Company's Capital Stock or the exchange or
conversion of one class or series of the Company's Capital Stock for another
class or series of the Company's Capital Stock; (iii) the purchase of fractional
interests in shares of any series of the Company's Common Stock pursuant to the
conversion or exchange provisions of such Common Stock or the security being
converted or exchanged; (iv) dividends or distributions in any series of the
Company's Common Stock (or rights to acquire Common Stock) or repurchases,
acquisitions or redemptions of Common Stock in connection with the issuance or
exchange of any series of Common Stock (or securities convertible into or
exchangeable for shares of the Company's Common Stock; or (v) redemptions,
exchanges or repurchases of any rights outstanding under a shareholder rights
plan or the declaration or payment thereunder of a dividend or distribution of
or with respect to rights in the future.

     The Forward Purchase Contracts and all obligations and rights of the
Company and the Holders thereunder, including, without limitation, the rights
and obligations of Holders to receive

                                       B-7

<PAGE>

and the obligation of the Company to pay Contract Adjustment Payments, if any,
or any Deferred Contract Adjustment Payments, and the rights and obligations of
Holders to purchase Common Stock, 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 Stock Purchase 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 to the Holders, at their addresses
as they appear in the Stripped Units Register. Upon and after the occurrence of
a Termination Event, the Collateral Agent shall release the Pledged Treasury
Securities from the Pledge in accordance with the provisions of the Pledge
Agreement.

     Upon registration of transfer of this Stripped Units 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
Forward Purchase Contract Agreement), by the terms of the Forward Purchase
Contract Agreement and the Forward Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Forward Purchase
Contracts evidenced by this Stripped Units 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.

     The Holder of this Stripped Units Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Forward Purchase
Contracts forming part of the Stripped Units evidenced hereby on its behalf as
its attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Forward 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 of the Forward Purchase
Contracts, covenants and agrees to perform such Holder's obligations under such
Forward Purchase Contracts, consents to the provisions of the Forward Purchase
Contract Agreement, irrevocably authorizes the Agent to enter into and perform
the Pledge Agreement on such Holder's behalf as attorney-in-fact, and consents
to and agrees to be bound by the Pledge of the Treasury Securities underlying
this Stripped Units Certificate pursuant to the Pledge Agreement, provided, that
upon a Termination Event, the rights of the Holder of such Units under the
Forward Purchase Contract may be enforced without regard to any other rights or
obligations. The Holder further covenants and agrees, that, to the extent and in
the manner provided in the Forward Purchase Contract Agreement and the Pledge
Agreement, but subject to the terms thereof, payments in respect of the Pledged
Treasury Securities, to be paid upon settlement of such Holder's obligations to
purchase Common Stock under the Forward Purchase Contract, shall be paid on the
Stock Purchase Date by the Collateral Agent to the Company in satisfaction of
such Holder's obligations under such Forward Purchase Contract and such Holder
shall acquire no right, title or interest in such payments.

     The Company and each Holder of any Stripped Units, and each Beneficial
Owner thereof, by its acceptance thereof or of its interest therein, further
agrees to treat (i) the formation of Stripped Units as the purchase of a unit
consisting of the Purchase Contract and the Treasury Securities and (ii) the
holder as the owner of the applicable interest in the Collateral Account,
including the Treasury Securities.

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

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

     The Forward 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 Forward Purchase Contract Agreement is available for
inspection by any Holder at the Corporate Trust Office.
