                               TEXAS UTILITIES COMPANY

                                OFFICER'S CERTIFICATE

               Robert S. Shapard, the Treasurer of Texas Utilities Company
          (the "Company"), pursuant to the authority granted in the Board
          Resolutions of the Company dated February 19 and 20, 1998, and
          Sections 201, 301, 1501 and 1502 of the Indenture defined herein,
          does hereby certify to The Bank of New York (the "Trustee"), as
          Trustee under the Indenture of the Company (For Unsecured Debt
          Securities Series D and Series E) dated as of July 1, 1998 (the
          "Indenture") that:

          1.   The securities of the first series to be issued under the
               Indenture shall be designated "6.37% Series D Senior Notes
               due 2003" (the "Series D Notes").  The securities of the
               second series to be issued under the Indenture shall be
               designated "6.50% Series E Senior Notes due 2004" (the
               "Series E Notes" and, together with the Series D Notes,
               hereinafter sometimes referred to as the "Senior Notes"). 
               All capitalized terms used in this certificate which are not
               defined herein shall have the meanings set forth in the
               Indenture;

          2.   The Series D Notes shall be limited in aggregate principal
               amount to $373,750,000 at any time Outstanding, except as
               contemplated in Section 301(b) of the Indenture.  The Series
               E Notes shall be limited in aggregate principal amount to
               $373,750,000 at any time Outstanding, except as contemplated
               in Section 301(b) of the Indenture;

          3.   The Series D Notes shall mature and the principal shall be
               due and payable together with all accrued and unpaid
               interest thereon on August 16, 2003.  The Series E Notes
               shall mature and the principal shall be due and payable
               together with all accrued and unpaid interest thereon on
               August 16, 2004;

          4.   The Series D Notes and the Series E Notes shall be issued in
               the denominations of $25 and integral multiples thereof;
 
          5.   The Series D Notes shall bear interest initially at the rate
               of 6.37% per annum payable quarterly in arrears on February
               16, May 16, August 16 and November 16 of each year (each, an
               "Interest Payment Date") commencing August 16, 1998.  The
               Series E Notes shall bear interest initially at the rate of
               6.50% per annum payable quarterly in arrears on each
               Interest Payment Date commencing August 16, 1998.
 
               The amount of interest payable on the Series D Notes and the
               Series E Notes will be computed on the basis of a 360-day
               year of twelve 30-day months. Interest on the Series D Notes
               and the Series E Notes will accrue from the original date of
               issuance, but if interest has been paid on such Series D
               Notes or Series E Notes, as applicable, then from the most
               recent Interest Payment Date to which interest has been paid
               or duly provided for. In the event that any Interest Payment
               Date is not a Business Day, then payment of interest payable
               on such date will be made on the next succeeding day which
               is a Business Day (and without any interest or other payment
               in respect of such delay), except that, if such Business Day
               is in the next succeeding calendar year, then such payment
               shall be made on the immediately preceding Business Day, in
               each case, with the same force and effect as if made on such
               Interest Payment Date;

               The interest rate on the Series D Notes that remain
               Outstanding on and after August 16, 2001 (the "First
               Purchase Contract Settlement Date") will be reset on the
               third Business Day immediately preceding the First Purchase
               Contract Settlement Date to the rate (the "Series D Reset
               Rate") determined by a Reset Agent, appointed by the Company
               (the "Reset Agent") in the manner described below.  From and
               after the First Purchase Contract Settlement Date, the
               Series D Notes will bear interest at the Series D Reset
               Rate.

               The interest rate on the Series E Notes that remain
               Outstanding on and after August 16, 2002 (the "Second
               Purchase Contract Settlement Date") will be reset on the
               third Business Day immediately preceding the Second Purchase
               Contract Settlement Date to the rate (the "Series E Reset
               Rate") determined by the applicable Reset Agent in the
               manner described below.  From and after the Second Purchase
               Contract Settlement Date, the Series E Notes will bear
               interest at the Series E Reset Rate.

               On the tenth Business Day immediately preceding the
               applicable Purchase Contract Settlement Date, the Reset
               Agent will select the Two-Year Benchmark Treasury, as
               defined below, to be used to determine the applicable Reset
               Rate (which will be the Series D Reset Rate in connection
               with the First Purchase Contract Settlement Date and the
               Series E Reset Rate in connection with the Second Purchase
               Contract Settlement Date).  On the same day, the Reset Agent
               will determine the spread (the "Reset Spread") which, in the
               opinion of such Reset Agent, when added to the rate on the
               Two-Year Benchmark Treasury on the third Business Day prior
               to the applicable Purchase Contract Settlement Date, will
               equal the interest rate the Senior Notes of the applicable
               Series (which will be the Series D Notes in connection with
               the First Purchase Contract Settlement Date and the Series E
               Notes in connection with the Second Purchase Contract
               Settlement Date) should bear in order to have an approximate
               market value on the third Business Day preceding the
               applicable Purchase Contract Settlement Date of 100.5% of
               their aggregate principal amount, plus accrued and unpaid
               interest, if any; provided, that the Company may limit the
               Series D Reset Rate to be no higher than the rate on the
               Two-Year Benchmark Treasury on third Business Day
               immediately preceding the First Purchase Contract Settlement
               Date plus 200 basis points (2.0%) and the Series E Reset
               Rate to be no higher than the rate on the Two-Year Treasury
               on the third Business Day immediately preceding the Second
               Purchase Contract Settlement Date plus 200 basis points
               (2.0%).  In no event shall the Series D Reset Rate or the
               Series E Reset Rate exceed the maximum permitted by
               applicable law.

               On such tenth Business Day immediately preceding the
               applicable Purchase Contract Settlement Date, the Company
               shall announce the applicable Reset Spread and the
               applicable Two-Year Benchmark Treasury (the "Reset
               Announcement Date").  The Company will cause a notice of the
               applicable Reset Spread and applicable Two-Year Benchmark
               Treasury to be published on the Business Day following the
               applicable Reset Announcement Date by publication in a
               newspaper in the English language of general circulation in
               The City of New York and generally published each Business
               Day, which is expected to be The Wall Street Journal.

               The Company will request, not later than 7 nor more than 15
               calendar days prior to each Reset Announcement Date that
               DTC, defined below, notify its participants holding
               beneficial interests in the Senior Notes of such applicable
               Reset Announcement Date and of the procedures that must be
               followed by the holders of such Senior Notes wishing to
               offer their Senior Notes of the appropriate series (which in
               the case of the First Purchase Contract Settlement Date will
               be the Series D Notes, and in the case of the Second
               Purchase Contract Settlement Date will be the Series E
               Notes) in the applicable Remarketing.

               Pursuant to one or more Remarketing Agreements ("Remarketing
               Agreements") to be entered into by the Company and one or
               more nationally recognized investment banking firms chosen
               by the Company, as the remarketing Agent (the "Remarketing
               Agent"), in connection with each Purchase Contract
               Settlement Date, on or prior to the fifth Business Day
               immediately preceding the applicable Purchase Contract
               Settlement Date, but not earlier than the Interest Payment
               Date immediately preceding such Purchase Contract Settlement
               Date, each Holder of Senior Notes of the applicable Series
               (which in the case of the First Purchase Contract Settlement
               Date shall be the Series D Notes and in the case of the
               Second Purchase Contract Settlement Date shall be the Series
               E Notes) may elect to have such Senior Notes of such Series
               remarketed (the applicable "Remarketing") by tendering such
               Senior Notes, along with a notice of such election, to the
               Custodial Agent under, and in accordance with, the Pledge
               Agreement, defined below.  Holders of Senior Notes electing
               to have their Senior Notes remarketed will also have the
               right to withdraw such election on or prior to the fifth
               Business day immediately preceding the applicable Purchase
               Contract Settlement Date by notice to the Custodial Agent in
               accordance with the provisions of the Pledge Agreement.
 
               On the third Business Day immediately preceding the First
               Purchase Contract Settlement Date, the applicable Reset
               Agent shall determine the Series D Reset Rate for the Series
               D Notes by adding the applicable Reset Spread to the rate
               for Two-Year Benchmark Treasury on such date.  On the third
               Business Day immediately preceding the Second Purchase
               Contract Settlement Date, the applicable Reset Agent shall
               determine the Series E Reset Rate for the Series E Notes by
               adding the applicable Reset Spread to the rate for the Two-
               Year Benchmark Treasury on such date.
 
               The Remarketing Agent will use its reasonable efforts to
               remarket, on the third Business Day immediately preceding
               the applicable Purchase Contract Settlement Date, the Senior
               Notes tendered for such Remarketing for settlement on such
               Purchase Contract Settlement Date at a price of
               approximately 100.5% of the aggregate principal amount of
               such tendered Senior Notes, plus accrued and unpaid
               interest, if any.  After deducting as the remarketing fee an
               amount not exceeding 25 basis points (.25%) of the aggregate
               principal amount of the Senior Notes so remarketed from any
               amount of the proceeds of such remarketing in excess of the
               aggregate principal amount of the Senior Notes so
               remarketed, plus such accrued and unpaid interest, the
               Remarketing Agent will remit the entire amount of the
               proceeds of such remarketing to the Collateral Agent (with
               respect to Senior Notes that had been components of Income
               PRIDES) or the Custodial Agent (with respect to other Senior
               Notes) in each case under the Pledge Agreement to be
               distributed to holders as provided in the Pledge Agreement. 
               If the Remarketing Agent cannot remarket the Senior Notes
               tendered for a Remarketing at a price not less than the
               aggregate principal amount of such tendered Senior Notes,
               plus accrued and unpaid interest, if any, or if a condition
               precedent to a Remarketing shall not have been fulfilled,
               then such Remarketing shall be deemed to be a Failed
               Remarketing with respect to such series of Senior Notes.

               The "Two-Year Benchmark Treasury" on a particular
               determination date shall mean direct obligations of the
               United States (which may be obligations traded on a
               when-issued basis only) having a maturity comparable to the
               remaining term to maturity of the applicable series of
               Senior Notes, as agreed upon by the Company and the
               applicable Reset Agent.  The rate for the Two-Year Benchmark
               Treasury will be the bid side rate displayed at 10:00 A.M.,
               New York City time, on the third Business Day immediately
               preceding the applicable Purchase Contract Settlement Date
               in the Telerate system (or if the Telerate system is (a) no
               longer available on the third Business Day immediately
               preceding such Purchase Contract Settlement Date or (b) in
               the opinion of the applicable Reset Agent (after
               consultation with the Company) no longer an appropriate
               system from which to obtain such rate, such other nationally
               recognized quotation system as, in the opinion of the
               applicable Reset Agent (after consultation with the
               Company), is appropriate).  If such rate is not so
               displayed, the rate for the Two-Year Benchmark Treasury
               shall be, as calculated by the applicable Reset Agent, the
               yield to maturity for the Two-Year Benchmark Treasury,
               expressed as a bond equivalent on the basis of a year of 365
               or 366 days, as applicable, and applied on a daily basis,
               and computed by taking the arithmetic mean of the secondary
               market bid rates, as of 10:30 A.M., New York City time, on
               the third Business Day immediately preceding the applicable
               Purchase Contract Settlement Date of three leading United
               States government securities dealers selected by the
               applicable Reset Agent (after consultation with the Company)
               (which may include the applicable Reset Agent or an
               affiliate thereof).
 
          6.   Each installment of interest on a Series D Note and on a
               Series E Note shall be payable to the Person in whose name
               such Series D Note or such Series D Note is registered at
               the close of business on the Regular Record Date for such
               interest installment, which shall be the Business Day next
               preceding the corresponding Interest Payment Date for the
               Senior Notes.  The Security Registrar may, but shall not be
               required to, register the transfer of Senior Notes during
               the ten days immediately preceding an Interest Payment Date. 
               Any installment of interest on the Series D Notes or on the
               Series E Notes not punctually paid or duly provided for
               shall forthwith cease to be payable to the Holders of such
               Series D Notes or of the Series E Notes on such Regular
               Record Date, and may be paid to the Persons in whose name
               such Series D Notes or such Series E Notes, respectively,
               are registered at the close of business on a Special Record
               Date to be fixed by the Trustee for the payment of such

               prior to such Special Record Date, or may be paid at any
               time in any other lawful manner not inconsistent with the

               D Notes and the Series E Notes may be listed, and upon such
               notice as may be required by such exchange, all as more
               fully provided in the Indenture;

               of the persons entitled thereto or by wire transfer to an
               account designated by the person entitled thereto.  Notices

               one or more Officer's Certificates, any such office or
               agency and such agent.  The Trustee will initially be the

          8.   If a Tax Event shall occur and be continuing, the Company
               may, at its option, redeem the Senior Notes in whole (but
               not in part) at any time at a Redemption Price equal to, for
               each Senior Note, the Redemption Amount plus accrued and
               unpaid interest thereon, to the date of redemption (the "Tax
               Event Redemption Date").  If such Tax Event Redemption
               occurs prior to the Second Purchase Contract Settlement
               Date, the Redemption Price payable with respect to the
               Senior Notes pledged to the Collateral Agent under the

               Company, The Chase Manhattan Bank, as Collateral Agent,
               Custodial Agent and Securities Intermediary, and The Bank of
               New York, as Purchase Contract Agent, (the "Pledge
               Agreement") will be paid to the Collateral Agent on the Tax
               Event Redemption Date on or prior to 12:30 p.m., New York
               City time, by check or wire transfer in immediately
               available funds at such place and at such account as may be
               designated by the Collateral Agent in exchange for the

               change in, the laws (or any regulations thereunder) of the
               United States or any political subdivision or taxing
               authority thereof or therein affecting taxation, (b) any
               amendment to or change in an interpretation or application
               of such laws or regulations by any legislative body, court,
               governmental agency or regulatory authority or (c) any
               interpretation or pronouncement by any such legislative
               body, court, governmental agency or regulatory authority

               regulations that differs from the generally accepted
               position on the date the Senior Notes are issued, which
               amendment, change or proposed change is effective or which
               interpretation or pronouncement is announced on or after the
               date of issuance of the Senior Notes, there is more than an
               insubstantial risk that interest payable by the Company on
               the Senior Notes would not be deductible, in whole or in
               part, by the Company for United States federal income tax
               purposes.

               Notice of any redemption will be mailed at least 30 days but
               not more than 60 days before the redemption date to each
               registered Holder of Senior Notes to be prepaid at its
               registered address as more fully provided in the Indenture. 
               Unless the Company defaults in payment of the Redemption
               Price, on and after the redemption date interest shall cease
               to accrue on such Senior Notes.

               of the principal amount thereof, will not recognize income,
               gain or loss for United States federal income tax purposes
               as a result of the satisfaction and discharge of the

               subject to United States federal income tax on the same
               amounts, at the same times and in the same manner as if such

          13.  The Series D Notes and the Series E Notes shall have such
               other terms and provisions as are provided in the forms
               thereof set forth in Exhibit A and Exhibit B hereto,

                         6.37% SERIES D SENIOR NOTE DUE 2003


                    TEXAS UTILITIES COMPANY, a corporation duly organized
          and existing under the laws of the State of Texas (herein
          referred to as the "Company", which term includes any successor
          Person under the Indenture), for value received, hereby promises
          to pay to 

          or registered assigns, the principal sum of ____________________
          Dollars on August 16, 2003, and to pay interest on said principal
          sum quarterly on February 16, May 16, August 16 and November 16
          of each year (each an Interest Payment Date) commencing August
          16, 1998, initially at the rate of 6.37% per annum until August
          16, 2001, and at the Series D Reset Rate thereafter until the
          principal hereof is paid or made available for payment.  Interest
          on the Securities of this series will accrue from July 22, 1998,
          to the first Interest Payment Date, and thereafter will accrue
          from the last Interest Payment Date to which interest has been
          paid or duly provided for. In the event that any Interest Payment
          Date is not a Business Day, then payment of interest payable on
          such date will be made on the next succeeding day which is a
          Business Day (and without any interest or other payment in
          respect of such delay), except that, if such Business Day is in
          the next succeeding calendar year, then such payment shall be
          made on the immediately preceding Business Day, in each case,
          with the same force and effect as if made on the Interest Payment
          Date. The interest so payable, and punctually paid or duly
          provided for, on any Interest Payment Date will, as provided in
          such Indenture, be paid to the Person in whose name this Security
          (or one or more Predecessor Securities) is registered at the
          close of business on the Regular Record Date for such interest,
          which shall be the [__] Business Day next preceding the
          corresponding Interest Payment Date.  Any such interest not so
          punctually paid or duly provided for will forthwith cease to be
          payable to the Holder on such Regular Record Date and may either
          be paid to the Person in whose name this Security (or one or more
          Predecessor Securities) is registered at the close of business on
          a Special Record Date for the payment of such Defaulted Interest
          to be fixed by the Trustee, notice whereof shall be given to
          Holders of Securities of this series not less than 10 days prior
          to such Special Record Date, or be paid at any time in any other
          lawful manner not inconsistent with the requirements of any
          securities exchange on which the Securities of this series may be

                           [FORM OF REVERSE OF SENIOR NOTE]


                    This Security is one of a duly authorized issue of
          securities of the Company (herein called the "Securities"),
          issued and to be issued in one or more series under an Indenture
          (for Unsecured Debt Securities Series D and Series E), dated as
          of July 1, 1998 (herein, together with any amendments thereto,
          called the "Indenture", which term shall have the meaning
          assigned to it in such instrument), between the Company and The
          Bank of New York, as Trustee (herein called the "Trustee", which
          term includes any successor trustee under the Indenture), and
          reference is hereby made to the Indenture, including the Board
          Resolutions and Officer's Certificate filed with the Trustee on
          July 22, 1998 creating the series designated on the face hereof,
          for a statement of the respective rights, limitations of rights,
          duties and immunities thereunder of the Company, the Trustee and
          the Holders of the Securities and of the terms upon which the
          Securities are, and are to be, authenticated and delivered.  This
          Security is one of the series designated on the face hereof,
          limited in aggregate principal amount to $373,750,000.
 
                   If a Tax Event shall occur and be continuing, the
          Company may, at its option, redeem the Securities of this series
          in whole (but not in part) at any time at a Redemption Price
          equal to the Redemption Amount plus accrued and unpaid interest
          thereon to the Tax Event Redemption Date.  

                    The Holder of this Security may, on or prior to the
          fifth Business Day immediately preceding August 16, 2001, tender
          this Security for Remarketing to The Chase Manhattan Bank, as
          Custodial Agent, in accordance with the Pledge Agreement dated as
          of July 1, 1998 among the Company, The Bank of New York and The
          Chase Manhattan Bank, as Collateral Agent, Custodial Agent and
          Securities Intermediary.
 
                    If a Failed Remarketing has occurred with respect to
          Securities of this series, each holder of Securities of this
          series who holds such Securities on the day immediately following
          the First Purchase Contract Settlement Date shall have the right
          to put such holder's Securities of this series to the Company on
          September 1, 2001 (the "Put Option Exercise Date"), upon at least
          three Business Days' prior notice, at a price equal to the
          principal amount of such Securities, plus accrued and unpaid
          interest, if any thereon (the "Repayment Price"). 
 
                    In order for the Securities to be so repurchased, the
          Company must receive, on or prior to 5:00 p.m. New York City Time
          on the third Business Day immediately preceding the Put Option
          Exercise Date, at the then principal executive offices of the
          Company, the Securities of this series to be repurchased with the
          form entitled "Option to Elect Repayment" on the reverse of or
          otherwise accompanying such Securities duly completed.  Any such
          notice received by the Company shall be irrevocable.  All
          questions as to the validity, eligibility (including time of
          receipt) and acceptance of the Securities of this series for
          repayment shall be determined by the Company, whose determination
          shall be final and binding.  The payment of the Repayment Price
          in respect of such Securities of this series shall be made,
          either through the Trustee or the Company acting as Paying Agent,
          no later than 12:00 noon, New York City time, on the Put Option
          Exercise Date.

                    The Indenture contains provisions for defeasance at any
          time of the entire indebtedness of this Security upon compliance
          with certain conditions set forth in the Indenture.

                    If an Event of Default with respect to Securities of
          this series shall occur and be continuing, the principal of the
          Securities of this series may be declared due and payable in the
          manner and with the effect provided in the Indenture.

                    The Indenture permits, with certain exceptions as
          therein provided, the amendment thereof and the modification of
          the rights and obligations of the Company and the rights of the
          Holders of the Securities of each series to be affected under the
          Indenture at any time by the Company and the Trustee with the
          consent of the Holders of a majority in principal amount of the
          Securities at the time Outstanding of all series to be affected. 
          The Indenture contains provisions permitting the Holders of a
          majority in aggregate principal amount of the Securities of all
          series then Outstanding to waive compliance by the Company with
          certain provisions of the Indenture.  The Indenture also contains
          provisions permitting the Holders of specified percentages in
          principal amount of the Securities of each series at the time
          Outstanding, on behalf of the Holders of all Securities of such
          series, to waive compliance by the Company with certain
          provisions of the Indenture and certain past defaults under the
          Indenture and their consequences.  Any such consent or waiver by
          the Holder of this Security shall be conclusive and binding upon
          such Holder and upon all future Holders of this Security and of
          any Security issued upon the registration of transfer hereof or
          in exchange herefor or in lieu hereof, whether or not notation of
          such consent or waiver is made upon this Security.

                    As provided in and subject to the provisions of the
          Indenture, the Holder of this Security shall not have the right
          to institute any proceeding with respect to the Indenture or for
          the appointment of a receiver or trustee or for any other remedy
          thereunder, unless such Holder shall have previously given the
          Trustee written notice of a continuing Event of Default with
          respect to the Securities of this series, the Holders of a
          majority in aggregate principal amount of the Securities of all
          series at the time Outstanding in respect of which an Event of
          Default shall have occurred and be continuing shall have made
          written request to the Trustee to institute proceedings in
          respect of such Event of Default as Trustee and offered the
          Trustee reasonable indemnity, and the Trustee shall not have
          received from the Holders of a majority in aggregate principal
          amount of Securities of all series at the time Outstanding in
          respect of which an Event of Default shall have occurred and be
          continuing a direction inconsistent with such request, and shall
          have failed to institute any such proceeding, for 60 days after
          receipt of such notice, request and offer of indemnity.  The
          foregoing shall not apply to any suit instituted by the Holder of
          this Security for the enforcement of any payment of principal
          hereof or any premium or interest hereon on or after the
          respective due dates expressed herein.

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

                    The Securities of this series are issuable only in
          registered form without coupons in denominations of $25.  As
          provided in the Indenture and subject to certain limitations
          therein set forth, Securities of this series are exchangeable for
          a like aggregate principal amount of Securities of this series
          and of like tenor and of authorized denominations, as requested
          by the Holder surrendering the same.

                    No service charge shall be made for any such
          registration of transfer or exchange, but the Company may require
          payment of a sum sufficient to cover any tax or other
          governmental charge payable in connection therewith.

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

                    All terms used in this Security which are defined in
          the Indenture shall have the meanings assigned to them in the
          Indenture and in the Officer's Certificate establishing the terms
          of the Securities of this Series.

                         6.50% SERIES E SENIOR NOTE DUE 2004


                    TEXAS UTILITIES COMPANY, a corporation duly organized
          and existing under the laws of the State of Texas (herein
          referred to as the "Company", which term includes any successor
          Person under the Indenture), for value received, hereby promises
          to pay to 

          or registered assigns, the principal sum of ____________________
          Dollars on August 16, 2004, and to pay interest on said principal
          sum quarterly on February 16, May 16, August 16 and November 16
          of each year (each an Interest Payment Date) commencing August
          16, 1998, initially at the rate of 6.50% per annum until August
          16, 2002, and at the Series E Reset Rate thereafter until the
          principal hereof is paid or made available for payment.  Interest
          on the Securities of this series will accrue from July 22, 1998,
          to the first Interest Payment Date, and thereafter will accrue
          from the last Interest Payment Date to which interest has been
          paid or duly provided for. In the event that any Interest Payment
          Date is not a Business Day, then payment of interest payable on
          such date will be made on the next succeeding day which is a
          Business Day (and without any interest or other payment in
          respect of such delay), except that, if such Business Day is in
          the next succeeding calendar year, then such payment shall be
          made on the immediately preceding Business Day, in each case,
          with the same force and effect as if made on the Interest Payment
          Date. The interest so payable, and punctually paid or duly
          provided for, on any Interest Payment Date will, as provided in
          such Indenture, be paid to the Person in whose name this Security
          (or one or more Predecessor Securities) is registered at the
          close of business on the Regular Record Date for such interest,
          which shall be the [__] Business Day next preceding the
          corresponding Interest Payment Date.  The Security Registrar may,
          but shall not be required to, register the transfer of this
          Security in whole or in part during the ten days immediately
          preceding an Interest Payment Date.  Any such interest not so
          punctually paid or duly provided for will forthwith cease to be
          payable to the Holder on such Regular Record Date and may either
          be paid to the Person in whose name this Security (or one or more
          Predecessor Securities) is registered at the close of business on
          a Special Record Date for the payment of such Defaulted Interest
          to be fixed by the Trustee, notice whereof shall be given to
          Holders of Securities of this series not less than 10 days prior
          to such Special Record Date, or be paid at any time in any other
          lawful manner not inconsistent with the requirements of any
          securities exchange on which the Securities of this series may be
          listed, and upon such notice as may be required by such exchange,
          all as more fully provided in the Indenture referred to on the
          reverse hereof.

                    Payment of the principal of (and premium, if any) and
          interest on this Security will be made at the office or agency of
          the Company maintained for that purpose in The City of New York,
          the State of New York in such coin or currency of the United
          States of America as at the time of payment is legal tender for
          payment of public and private debts, provided, however, that, at
          the option of the Company, interest on this Security may be paid
          by check mailed to the address of the person entitled thereto, as
          such address shall appear on the Security Register.  

                    Reference is hereby made to the further provisions of 
          this Security set forth on the reverse hereof, which further 
          provisions shall for all purposes have the same effect as if set 
          forth at this place.

                    Unless the certificate of authentication hereon has
          been executed by the Trustee referred to on the reverse hereof by
          manual signature, this Security shall not be entitled to any
          benefit under the Indenture or be valid or obligatory for any
          purpose.

                           [FORM OF REVERSE OF SENIOR NOTE]

                    This Security is one of a duly authorized issue of
          securities of the Company (herein called the "Securities"),
          issued and to be issued in one or more series under an Indenture
          (for Unsecured Debt Securities Series D and Series E), dated as
          of July 1, 1998 (herein, together with any amendments thereto,
          called the "Indenture", which term shall have the meaning
          assigned to it in such instrument), between the Company and The
          Bank of New York, as Trustee (herein called the "Trustee", which
          term includes any successor trustee under the Indenture), and
          reference is hereby made to the Indenture, including the Board
          Resolutions and Officer's Certificate filed with the Trustee on
          July 22, 1998 creating the series designated on the face hereof,
          for a statement of the respective rights, limitations of rights,
          duties and immunities thereunder of the Company, the Trustee and
          the Holders of the Securities and of the terms upon which the
          Securities are, and are to be, authenticated and delivered.  This
          Security is one of the series designated on the face hereof,
          limited in aggregate principal amount to $373,750,000.

                    If a Tax Event shall occur and be continuing, the
          Company may, at its option, redeem the Securities of this series
          in whole (but not in part) at any time at a Redemption Price
          equal to the Redemption Amount plus accrued and unpaid interest
          thereon to the Tax Event Redemption Date.  

                   The Holder of this Security may, on or prior to the
          fifth Business Day immediately preceding August 16, 2002, tender
          this Security for Remarketing to The Chase Manhattan Bank, as
          Custodial Agent, in accordance with the Pledge Agreement dated as
          of July 1, 1998 among the Company, The Bank of New York and The
          Chase Manhattan Bank, as Collateral Agent, Custodial Agent and
          Securities Intermediary.

                    If a Failed Remarketing has occurred with respect to
          Securities of this series, each holder of Securities of this
          series who holds such Securities on the day immediately following
          the First Purchase Contract Settlement Date shall have the right
          to put such holder's Securities of this series to the Company on
          September 1, 2002 (the "Put Option Exercise Date"), upon at least
          three Business Days' prior notice, at a price equal to the
          principal amount of such Securities, plus accrued and unpaid
          interest, if any thereon (the "Repayment Price"). 

                    In order for the Securities to be so repurchased, the
          Company must receive, on or prior to 5:00 p.m. New York City Time
          on the third Business Day immediately preceding the Put Option
          Exercise Date, at the then principal executive offices of the
          Company, the Securities of this series to be repurchased with the
          form entitled "Option to Elect Repayment" on the reverse of or
          otherwise accompanying such Securities duly completed.  Any such
          notice received by the Trustee shall be irrevocable.  All
          questions as to the validity, eligibility (including time of
          receipt) and acceptance of the Securities of this series for
          repayment shall be determined by the Company, whose determination
          shall be final and binding.  The payment of the Repayment Price
          in respect of such Securities of this series shall be made,
          either through the Trustee or the Company acting as Paying Agent,
          no later than 12:00 noon, New York City time, on the Put Option
          Exercise Date.

                    The Indenture contains provisions for defeasance at any
          time of the entire indebtedness of this Security upon compliance
          with certain conditions set forth in the Indenture.

                    If an Event of Default with respect to Securities of
          this series shall occur and be continuing, the principal of the
          Securities of this series may be declared due and payable in the
          manner and with the effect provided in the Indenture.

                    The Indenture permits, with certain exceptions as
          therein provided, the amendment thereof and the modification of
          the rights and obligations of the Company and the rights of the
          Holders of the Securities of each series to be affected under the
          Indenture at any time by the Company and the Trustee with the
          consent of the Holders of a majority in principal amount of the
          Securities at the time Outstanding of all series to be affected. 
          The Indenture contains provisions permitting the Holders of a
          majority in aggregate principal amount of the Securities of all
          series then Outstanding to waive compliance by the Company with
          certain provisions of the Indenture.  The Indenture also contains
          provisions permitting the Holders of specified percentages in
          principal amount of the Securities of each series at the time
          Outstanding, on behalf of the Holders of all Securities of such
          series, to waive compliance by the Company with certain
          provisions of the Indenture and certain past defaults under the
          Indenture and their consequences.  Any such consent or waiver by
          the Holder of this Security shall be conclusive and binding upon
          such Holder and upon all future Holders of this Security and of
          any Security issued upon the registration of transfer hereof or
          in exchange herefor or in lieu hereof, whether or not notation of
          such consent or waiver is made upon this Security.

                    As provided in and subject to the provisions of the
          Indenture, the Holder of this Security shall not have the right
          to institute any proceeding with respect to the Indenture or for
          the appointment of a receiver or trustee or for any other remedy
          thereunder, unless such Holder shall have previously given the
          Trustee written notice of a continuing Event of Default with
          respect to the Securities of this series, the Holders of a
          majority in aggregate principal amount of the Securities of all
          series at the time Outstanding in respect of which an Event of
          Default shall have occurred and be continuing shall have made
          written request to the Trustee to institute proceedings in
          respect of such Event of Default as Trustee and offered the
          Trustee reasonable indemnity, and the Trustee shall not have
          received from the Holders of a majority in aggregate principal
          amount of Securities of all series at the time Outstanding in
          respect of which an Event of Default shall have occurred and be
          continuing a direction inconsistent with such request, and shall
          have failed to institute any such proceeding, for 60 days after
          receipt of such notice, request and offer of indemnity.  The
          foregoing shall not apply to any suit instituted by the Holder of
          this Security for the enforcement of any payment of principal
          hereof or any premium or interest hereon on or after the
          respective due dates expressed herein.

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

                    The Securities of this series are issuable only in
          registered form without coupons in denominations of $25.  As
          provided in the Indenture and subject to certain limitations
          therein set forth, Securities of this series are exchangeable for
          a like aggregate principal amount of Securities of this series
          and of like tenor and of authorized denominations, as requested
          by the Holder surrendering the same.

                    No service charge shall be made for any such
          registration of transfer or exchange, but the Company may require
          payment of a sum sufficient to cover any tax or other
          governmental charge payable in connection therewith.

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

                    All terms used in this Security which are defined in
          the Indenture shall have the meanings assigned to them in the
          Indenture and in the Officer's Certificate establishing the terms
          of the Securities of this Series.

          Agreement, upon any application or request by the Company to the

                    Every certificate or opinion with respect to compliance
          with a condition or covenant provided for in this Agreement shall
          include:
              

             
                    (1)  a statement that each individual signing such
               certificate or opinion has read such covenant or condition
               and the definitions herein relating thereto;

                    (3)  a statement that, in the opinion of each such
               individual, he or she has made such examination or
               investigation as is necessary to enable such individual to
               express an informed opinion as to whether or not such
               covenant or condition has been complied with; and
              

             
                    (4)  a statement as to whether, in the opinion of each
               such individual, such condition or covenant has been
               complied with.
              

             
          SECTION 1.3.   FORM OF DOCUMENTS DELIVERED TO AGENT.
              

             
                    In any case where several matters are required to be
          certified by, or covered by an opinion of, any specified Person,
          it is not necessary that all such matters be certified by, or
          covered by the opinion of, only one such Person, or that they be
          so certified or covered by only one document, but one such Person
          may certify or give an opinion with respect to some matters and
          one or more other such Persons as to other matters, and any such
          Person may certify or give an opinion as to such matters in one
          or several documents.
              

             
                    Any certificate or opinion of an officer of the Company
          may be based, insofar as it relates to legal matters, upon a
          certificate or opinion of, or representations by, counsel, unless
          such officer knows, or in the exercise of reasonable care should
          know, that the certificate or opinion or representations with
          respect to the matters upon which his certificate or opinion is
          based are erroneous. Any such certificate or Opinion of Counsel
          may be based, insofar as it relates to factual matters, upon a
          certificate or opinion of, or representations by, an officer or
          officers of the Company stating that the information with respect
          to such factual matters is in the possession of the Company
          unless such counsel knows, or in the exercise of reasonable care
          should know, that the certificate or opinion or representations
          with respect to such matters are erroneous.
              

             
                    Where any Person is required to make, give or execute
          two or more applications, requests, consents, certificates,
          statements, opinions or other instruments under this Agreement,
          they may, but need not, be consolidated and form one instrument.
              

             
          SECTION 1.4.   ACTS OF HOLDERS; RECORD DATES.
              

             
                    (a)  Any request, demand, authorization, direction,
               notice, consent, waiver or other action provided by this
               Agreement to be given or taken by Holders may be embodied in
               and evidenced by one or more instruments of substantially
               similar tenor signed by such Holders in person or by agent
               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 shall be sufficient for
               any purpose of this Agreement and (subject to Section 7.1)
               conclusive in favor of the Agent and the Company, if made in
               the manner provided in this Section.
              

             
                    (b)  The fact and date of the execution by any Person
               of any such instrument or writing may be proved in any
               manner which the Agent deems sufficient.
              

             
                    (c)  The ownership of Securities shall be proved by the
               Income PRIDES Register or the Growth PRIDES 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
               Securities 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 Securities. If any record
               date is set pursuant to this paragraph, the Holders of the
               Outstanding Income PRIDES and the Outstanding Growth PRIDES,
               as the case may be, on such record date, and no other
               Holders, shall be entitled to take the relevant action with
               respect to the Income PRIDES or the Growth PRIDES 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 Securities 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 canceled
               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 Securities 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 Securities in the manner set forth in Section 1.6.
              

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

             
          SECTION 1.5.   NOTICES.
              

             
                    Any request, demand, authorization, direction, notice,
          consent, waiver or Act of Holders or other document provided or
          permitted by this Agreement to be made upon, given or furnished
          to, or filed with,
              

             
                    (1) the Agent by any Holder or by the Company shall be

               or at any other address previously furnished in writing by
               the Agent to the Holders and the Company; or
              

             
                    (2) the Company by the Agent or by any Holder shall be
               sufficient for every purpose hereunder (unless otherwise
               herein expressly provided) if made, given, furnished or
               filed in writing and personally delivered or mailed,
               first-class postage prepaid, to the Company at Texas
               Utilities Company, Energy Plaza, 1601 Bryan Street, Dallas,

               previously furnished in writing to the Agent by the Company;
               or
              

             
                    (3) the Collateral Agent by the Agent, the Company or
               any Holder shall be sufficient for every purpose hereunder
               (unless otherwise herein expressly provided) if made, given,
               furnished or filed in writing and personally delivered or
               mailed, first-class postage prepaid, addressed to the
               Collateral Agent at The Chase Manhattan Bank at 450 West
               33rd Street, New York, New York 10001,
               Attention:                  , or at any other address
               previously furnished in writing by the Collateral Agent to
               the Agent, the Company and the Holders; or
              

             
                    (4) the Indenture Trustee by the Company shall be
               sufficient for every purpose hereunder (unless otherwise
               herein expressly provided) if made, given, furnished or
               filed in writing and personally delivered or mailed,
               first-class postage prepaid, addressed to the Indenture
               Trustee at The Bank of New York, 101 Barclay Street, New
               York, New York 10286, Attention: Vice President, Corporate
               Trust Administration, other address previously furnished in
               writing by the Indenture Trustee to the Company.
              

             
          SECTION 1.6.   NOTICE TO HOLDERS; WAIVER.
              

             
                    Where this Agreement provides for notice to Holders of
          any event, such notice shall be sufficiently given (unless
          otherwise herein expressly provided) if in writing and mailed,
          first-class postage prepaid, to each Holder affected by such
          event, at its address as it appears in the applicable Register,
          not later than the latest date, and not earlier than the earliest
          date, prescribed for the giving of such notice. In any case where
          notice to Holders is given by mail, neither the failure to mail
          such notice, nor any defect in any notice so mailed to any
          particular Holder shall affect the sufficiency of such notice
          with respect to other Holders. Where this 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.
              

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

             
          SECTION 1.7.   EFFECT OF HEADINGS AND TABLE OF CONTENTS.
              

             
                    The Article and Section headings herein and the Table

                    Each Income PRIDES Certificate shall evidence the
          number of Income PRIDES specified therein, with each such Income
          PRIDES representing the ownership by the Holder thereof of a

          by such Holder pursuant to the Pledge Agreement, and the rights

          to purchase the Common Stock of the Company.
              

             
                    Each Growth PRIDES Certificate shall evidence the
          number of Growth PRIDES specified therein, with each such Growth

          the First Purchase Contract Settlement Date, of a 1/40 undivided
          beneficial interest in both a 3-Year Treasury Security and a 4-
          Year Treasury Security and, on and after the First Purchase
          Contract Settlement Date, of a 1/40 undivided beneficial interest

          and the Company under one Purchase Contract.  The Agent as
          attorney-in-fact for, and on behalf of, the Holder of each Growth

          Treasury Security forming a part of such Growth PRIDES, to the

          SECTION 3.3.   EXECUTION, AUTHENTICATION, DELIVERY AND DATING.
              

             
                    Subject to the provisions of Sections 3.13 and 3.14
          hereof, 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.
              

             
                    The Certificates shall be executed on behalf of the
          Company by its Chairman of the Board, its President, one of its
          Vice Presidents, its Treasurer, one of its Assistant Treasurers,
          its Secretary or one of its Assistant Secretaries. The signature
          of any of these officers on the Certificates may be manual or
          facsimile.
              

             
                    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.
              

             
                    No 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 Purchase
          Contracts evidenced by such Certificate.
              

             
                    Each Certificate shall be dated the date of its
          authentication.
              

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

             
          SECTION 3.4.   TEMPORARY CERTIFICATES.
              

             
                    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 forms set forth in
          Exhibit A and  Exhibit B hereto, 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
          Income PRIDES or Growth PRIDES are listed, or as may,
          consistently herewith, be determined by the officers of the
          Company executing such Certificates, as evidenced by their
          execution of the Certificates.
              

             
                    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 Income PRIDES or Growth PRIDES, 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 Income PRIDES or Growth PRIDES,
          as the case may be, evidenced thereby as definitive Certificates.
              

             
          SECTION 3.5.   REGISTRATION; REGISTRATION OF TRANSFER AND
                         EXCHANGE.
              

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

             
                    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 any
          authorized denominations, like tenor, and evidencing a like
          number of Income PRIDES  or Growth PRIDES, as the case may be.
              

             
                    At the option of the Holder, Certificates may be
          exchanged for other Certificates, of any authorized denominations
          and evidencing a like number of Income PRIDES or Growth PRIDES,
          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.
              

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

             
                    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.
              

             
                    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 3.6
          and 8.5 not involving any transfer.
              

             
                    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 during the period
          commencing on the Business Day immediately preceding a Purchase
          Contract Settlement Date and ending on such Purchase Contract
          Settlement Date or on or after the Termination Date.
              

             
          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 by, or on behalf of, the
          Company. Such Global Certificate shall initially be registered on
          the books and records of the Company 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 the payment of Contract Adjustment Payments, if
               any, and receiving approvals, votes or consents hereunder)
               as the Holder of the Securities 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 and
               receive and transmit payments of Contract Adjustment
               Payments to such 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 Securities 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 Securities,
          the Company may, in its sole discretion, appoint a successor
          Clearing Agency with respect to the Securities.
              

             
          SECTION 3.9.   DEFINITIVE CERTIFICATES.
              

             
                    If (i) a Clearing Agency elects to discontinue its
          services as securities depositary with respect to the Securities
          and a successor Clearing Agency is not appointed within 90 days
          after such discontinuance pursuant to Section 3.8, or (ii) the
          Company elects to terminate the book-entry system through the
          Clearing Agency with respect to the Securities, then upon
          surrender of the Global Certificates representing the Book-Entry
          Interests with respect to the Securities by the Clearing Agency,
          accompanied by registration instructions, the Company shall cause
          definitive Certificates to be delivered to Beneficial Owners in
          accordance with the instructions of the Clearing Agency. The
          Company 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.
              

             
                    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 Income PRIDES or
          Growth PRIDES, as the case may be, and bearing a Certificate
          number not contemporaneously outstanding.
              

             
                    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
          Income PRIDES or Growth PRIDES, as the case may be, and bearing a
          Certificate number not contemporaneously outstanding.
              

             
                    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 during the
          period commencing on the Business Day immediately preceding a
          Purchase Contract Settlement Date and such Purchase Contract
          Settlement Date or on or after the Termination Date.  In
          addition, 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 may (i) if the Second
          Purchase Contract Settlement Date has occurred, deliver the
          shares of Common Stock issuable in respect of the applicable
          portion of the Purchase Contracts forming a part of the
          Securities evidenced by such Certificate, or (ii) if a
          Termination Event shall have occurred, transfer the Debt
          Securities, the appropriate Applicable Ownership Interest in the
          Treasury Portfolio or the Treasury Securities, as the case may
          be, forming a part of the Securities represented by such
          Certificate to such Holder, in each case subject to the
          applicable conditions and in accordance with the applicable
          provisions of Article Five hereof.
              

             
                    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.
              

             
                    Every new Certificate issued pursuant to this Section
          in lieu of any destroyed, lost or stolen Certificate shall
          constitute an original additional contractual obligation of the
          Company and of the Holder in respect of the Security evidenced
          thereby, whether or not the destroyed, lost or stolen Certificate
          (and the Securities 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.
              

             
                    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.
              

             
                    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 on the Income PRIDES Register
          or the Growth PRIDES Register, as applicable, as the owner of the
          Income PRIDES or Growth PRIDES evidenced thereby, for the purpose
          of receiving interest on the Debt Securities or distributions on
          the maturing quarterly interest strips of the Treasury Portfolio,
          as applicable, receiving payments of Contract Adjustment
          Payments, performance of the Purchase Contracts and for all other
          purposes whatsoever, whether or not any interest on the Debt
          Securities or the Contract Adjustment Payments payable in respect
          of the Purchase Contracts constituting a part of the Income
          PRIDES or Growth PRIDES evidenced thereby 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.
              

             
                    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 treating the
          Clearing Agency as the sole Holder of such Global Certificate or
          from giving effect to any written certification, proxy or other
          authorization furnished by any Clearing Agency (or its nominee),
          as 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.
              

             
          SECTION 3.12.  CANCELLATION.
              

             
                    All Certificates surrendered for delivery of shares of
          Common Stock on or after the Second Purchase Contract Settlement
          Date, upon the transfer of Debt Securities, the appropriate
          Applicable Ownership Interest in the Treasury Portfolio or
          Treasury Securities, as the case may be, after the occurrence of
          a Termination Event or pursuant to an Early Settlement, or upon
          the registration of a transfer or exchange of a Security, or a
          Collateral Substitution or the re-establishment of an Income
          PRIDES shall, if surrendered to any Person other than the Agent,
          be delivered to the Agent and, if not already canceled, shall be
          promptly canceled 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 canceled 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 canceled as provided in this Section, except as
          expressly permitted by this Agreement. All canceled Certificates
          held by the Agent shall upon written request be returned to the
          Company.
              

             
                    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 delivered to the Agent canceled or for
          cancellation.
              

             
          SECTION 3.13.  ESTABLISHMENT OR REESTABLISHMENT OF GROWTH PRIDES.
              

             
                    A Holder of an Income PRIDES may, at any time on or
          prior to the fifth Business Day immediately preceding the Second
          Purchase Contract Settlement Date, create a Growth PRIDES and
          separate the Debt Securities or the appropriate Applicable
          Ownership Interest in the Treasury Portfolio, as applicable, from
          the related Purchase Contract in respect of such Income PRIDES by
          substituting 3-Year Treasury Securities and 4-Year Treasury
          Securities for all, but not less than all, of the Series D Note
          and the Series E Note, respectively, or appropriate Applicable
          Ownership Interest in the Treasury Portfolio, as the case may be,
          that form a part of such Income PRIDES in accordance with this
          Section 3.13; provided, however, that such Collateral
          Substitutions may not be made during the period from the fifth
          Business Day immediately preceding the First Purchase Contract
          Settlement Date through the First Purchase Contract Settlement
          Date, except that if a Tax Event Redemption has occurred and the
          Treasury Portfolio has become a component of the Income PRIDES,
          Holders of such Income PRIDES may make such Collateral
          Substitutions at any time on or prior to the second Business Day
          immediately preceding the Second Purchase Contract Settlement
          Date (but not during the period from the second Business Day
          immediately preceding the First Purchase Contract Settlement Date
          through the First Purchase Contract Settlement Date).  Holders
          may make Collateral Substitutions (i) only in integral multiples
          of 40 Income PRIDES if Debt Securities are being substituted by
          Treasury Securities, or (ii) only in integral multiples of
          1,600,000 Income PRIDES if the appropriate Applicable Ownership
          Interests in the Treasury Portfolio are being substituted by
          Treasury Securities.  To create 40 Growth PRIDES (if a Tax Event
          Redemption has not occurred), or 1,600,000 Growth PRIDES (if a
          Tax Event Redemption has occurred), the Income PRIDES Holder
          shall
              

             
                    (a) if a Tax Event Redemption has not occurred, (i)
               prior to the fifth Business Day preceding the First Purchase
               Contract Settlement Date, deposit with the Collateral Agent
               a 3-Year Treasury Security having a principal amount at
               maturity of $1,000 and a 4-Year Treasury Security having a
               principal amount at maturity of $1,000, or (ii) after the
               First Purchase Contract Settlement Date and prior to the
               fifth Business Day preceding the Second Purchase Contract
               Settlement Date, deposit with the Collateral Agent a 4-Year
               Treasury Security having a principal amount at maturity of
               $1,000; or
              

             
                    (b) if a Tax Event Redemption has occurred, (i) prior
               to the second Business Day immediately preceding the First
               Purchase Contract Settlement Date, deposit with the
               Collateral Agent 3-Year Treasury Securities having an
               aggregate principal amount at maturity of $40,000,000 and 4-
               Year Treasury Securities having an aggregate principal
               amount at maturity of $40,000,000, or (ii) after the First
               Purchase Contract Settlement Date and prior to the second
               Business Day immediately preceding the Second Purchase
               Contract Settlement Date, 4-Year Treasury Securities having
               an aggregate principal amount at maturity of $40,000,000;
               and
              

             
                    (c) in either case, (i) deliver cash to the Agent in an
               amount equal to the excess of the Contract Adjustment
               Payments that would have accrued on the Growth PRIDES being
               created by the Holder since the last Payment Date through
               the date of Collateral Substitution, over the Contract
               Adjustment Payments that have accrued over the same time
               period on the Income PRIDES being surrendered in connection
               with such Collateral Substitution, which amount the Agent
               shall promptly remit to the Company, and (ii) transfer the
               40 Income PRIDES, or, in the event a Tax Event Redemption
               has occurred, 1,600,000 Income PRIDES, to the Agent
               accompanied by a notice to the Agent, substantially in the
               form of Exhibit B to the Pledge Agreement, stating that the
               Holder has transferred the relevant types and amounts of
               Treasury Securities to the Collateral Agent and requesting
               that the Agent instruct the Collateral Agent to release the
               applicable Debt Securities or the appropriate Applicable
               Ownership Interest in the Treasury Portfolio, as the case
               may be, underlying such Income PRIDES, whereupon the Agent
               shall promptly give such instruction to the Collateral
               Agent, substantially in the form of Exhibit A to the Pledge
               Agreement. 
              

             
          Upon receipt of the Treasury Securities described in clause (a)
          or (b) above and the instructions described in clause (c) above,
          in accordance with the terms of the Pledge Agreement, the
          Collateral Agent will release from the Pledge, to the Agent, on
          behalf of the Holder, Debt Securities or the appropriate
          Applicable Ownership Interest in the Treasury Portfolio, as the
          case may be, that had been components of such Income PRIDES, free
          and clear of the Company's security interest therein, and upon
          receipt thereof the Agent shall promptly:
              

             
                    (i) cancel the related Income PRIDES surrendered
               and transferred;
              

             
                    (ii) transfer the Debt Securities or the
               appropriate Applicable Ownership Interest in the
               Treasury Portfolio, as the case may be, that had been
               components of such Income PRIDES to the Holder; and
              

             
                    (iii) authenticate, execute on behalf of such
               Holder and deliver a Growth PRIDES Certificate executed
               by the Company in accordance with Section 3.3
               evidencing the same number of Purchase Contracts as
               were evidenced by the canceled Income PRIDES.
              

             
                    Holders who elect to separate the Debt Securities or
          the appropriate Applicable Ownership Interest in the Treasury
          Portfolio, as the case may be, from the related Purchase
          Contracts and to substitute Treasury Securities for such Debt
          Securities or the appropriate Applicable Ownership Interest in
          the Treasury Portfolio, as the case may be, 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.
              

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

             
                    Except as described in this Section 3.13, for so long
          as the Purchase Contract underlying an Income PRIDES remains in
          effect, such Income PRIDES shall not be separable into its
          constituent parts, and the rights and obligations of the Holder
          in respect of the Debt Securities or the appropriate Applicable
          Ownership Interest in the Treasury Portfolio, as the case may be,
          and Purchase Contract comprising such Income PRIDES may be
          acquired, and may be transferred and exchanged, only as an entire
          Income PRIDES.
              

             
          SECTION 3.14.  ESTABLISHMENT OR REESTABLISHMENT OF INCOME PRIDES.
              

             
                    A Holder of a Growth PRIDES may, at any time on or
          prior to the fifth Business Day immediately preceding the Second
          Purchase Contract Settlement Date, create or recreate Income
          PRIDES by (a) depositing with the Collateral Agent Debt
          Securities or the appropriate Applicable Ownership Interest in
          the Treasury Portfolio, as the case may be, having an aggregate
          principal amount equal to the aggregate principal amount at
          maturity of, and in substitution for all, but not less than all,
          of the Treasury Securities comprising part of the Growth PRIDES
          in accordance with this Section 3.14; provided, however, that
          such substitutions may not be made during the period from the
          fifth Business Day immediately preceding the First Purchase
          Contract Settlement Date through the First Purchase Contract
          Settlement Date, except that if a Tax Event Redemption has
          occurred and the Treasury Portfolio has become a component of the
          Income PRIDES, Holders of Growth PRIDES may make such Collateral
          Substitutions at any time on or prior to the second Business Day
          immediately preceding the Second Purchase Contract Settlement
          Date (but not during the period from the second Business Day
          immediately preceding the First Purchase Contract Settlement Date
          through the First Purchase Contract Settlement Date).  Holders of
          Growth PRIDES may make such Collateral Substitutions and
          establish Income PRIDES only (i) in integral multiples of 40
          Growth PRIDES for 40 Income PRIDES if a Tax Event Redemption has
          not occurred, or (ii) in integral multiples of 1,600,000 Growth
          PRIDES for 1,600,000 Income PRIDES if a Tax Event Redemption has
          occurred.  To create 40 Income PRIDES (if a Tax Event Redemption
          has not occurred), or 1,600,000 Income PRIDES (if a Tax Event
          Redemption has occurred), the Growth PRIDES Holder shall
              

             
                    (a) if a Tax Event Redemption has not occurred, (i)
               prior to the fifth Business Day preceding the First Purchase
               Contract Settlement Date, deposit with the Collateral Agent
               $1,000 in aggregate principal amount of Series D Notes and
               $1,000 in aggregate principal amount of Series E Notes, or
               (ii) after the First Purchase Contract Settlement Date,
               deposit with the Collateral Agent $1,000 in aggregate
               principal amount of Series E Notes, or
              

             
                    (b) if a Tax Event Redemption has occurred, deposit
               with the Collateral Agent the Applicable Ownership Interest
               in the Treasury Portfolio for each Income PRIDES being
               created by the Holder, and having an aggregate principal
               amount of $80,000,000, or if, after the First Purchase
               Contract Settlement Date $40,000,000, and
              

             
                    (c) in either case, transfer and surrender the related
               40 Growth PRIDES, or in the event a Tax Event Redemption has
               occurred, 1,600,000 Income PRIDES, to the Agent accompanied
               by a notice to the Agent, substantially in the form of
               Exhibit B to the Pledge Agreement, stating that the Holder
               has transferred the relevant amount of Debt Securities or
               the appropriate Applicable Ownership Interest in the
               Treasury Portfolio, as the case may be, to the Collateral
               Agent and requesting that the Agent instruct the Collateral
               Agent to release the Treasury Securities underlying such
               Growth PRIDES, whereupon the Agent shall promptly give such
               instruction to the Collateral Agent, substantially in the
               form of Exhibit A to the Pledge Agreement.  
              

             
          Upon receipt of the Debt Securities or the appropriate Applicable
          Ownership Interest in the Treasury Portfolio, as the case may be,
          described in clause (a) or (b) above and the instructions
          described in clause (c) above, in accordance with the terms of
          the Pledge Agreement, the Collateral Agent will effect the
          release of the Treasury Securities having a corresponding
          aggregate principal amount from the Pledge to the Agent free and
          clear of the Company's security interest therein, and upon
          receipt thereof the Agent shall promptly:
              

             
                    (i) cancel the related Growth PRIDES surrendered
               and transferred;
              

             
                    (ii) transfer the Treasury Securities that had
               been components of such Growth PRIDES to the Holder;
               and
              

             
                    (iii) authenticate, execute on behalf of such
               Holder and deliver an Income PRIDES Certificate
               executed by the Company in accordance with Section 3.3
               evidencing the same number of Purchase Contracts as
               were evidenced by the canceled Growth PRIDES.
              

             
                    Holders who elect to separate Treasury Securities from
          the related Purchase Contract and to substitute Debt Securities
          or the Applicable Ownership Interest in the Treasury Portfolio,
          as the case may be, for such Treasury Securities 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.
              

             
                    In the event a Holder making a Collateral Substitution
          pursuant to this Section 3.14 fails to effect a book-entry
          transfer of the Growth PRIDES or fails to deliver a Growth PRIDES
          Certificate to the Agent after depositing the appropriate Debt
          Securities or Applicable Ownership Interest in the Treasury
          Portfolio with the Collateral Agent, the Treasury Securities
          constituting a part of such Growth PRIDES Certificate, and any
          interest 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 Growth PRIDES is so transferred or the Growth
          PRIDES is so delivered, or until such Holder provides evidence
          satisfactory to the Company and the Agent that such Growth PRIDES
          has been destroyed, lost or stolen, together with any indemnity
          that may be required by the Agent and the Company.
              

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

             
          SECTION 3.15.  TRANSFER OF COLLATERAL UPON OCCURRENCE OF
                         TERMINATION EVENT.
              

             
                    Upon the occurrence of a Termination Event and the
          transfer to the Agent of the Debt Securities, the appropriate
          Applicable Ownership Interest in the Treasury Portfolio or the
          Treasury Securities, as the case may be, underlying the Income
          PRIDES and the Growth PRIDES pursuant to the terms of the Pledge
          Agreement, the Agent shall request transfer instructions with
          respect to such Debt Securities or the appropriate 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
          Income PRIDES Register or the Growth PRIDES Register, as the case
          may be. Upon book-entry transfer of the Income PRIDES Certificate
          or Growth PRIDES Certificate or delivery of an Income PRIDES or
          Growth PRIDES to the Agent with such transfer instructions, the
          Agent shall transfer the Debt Securities, the Treasury Portfolio
          or Treasury Securities, as the case may be, underlying such
          Income PRIDES or Growth PRIDES, 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 of
          Income PRIDES or Growth PRIDES fails to effect such transfer or
          delivery, the Debt Securities, the appropriate Applicable
          Ownership Interest in the Treasury Portfolio or Treasury
          Securities, as the case may be, underlying such Income PRIDES or
          Growth PRIDES, as the case may be, and any interest thereon,
          shall be held in the name of the Agent or its nominee in trust
          for the benefit of such Holder, until such Income PRIDES or
          Growth PRIDES are transferred or the Income PRIDES Certificate or
          Growth PRIDES Certificate is surrendered or such Holder provides
          satisfactory evidence that such Income PRIDES Certificate or
          Growth PRIDES Certificate has been destroyed, lost or stolen,
          together with any indemnity that may be required by the Agent and
          the Company.  In the case of the Treasury Portfolio the Purchase
          Contract Agent may dispose of the subject securities for cash and
          pay the applicable portion of such cash to the Holders in lieu of
          such Holders Applicable Ownership interest in such Treasury
          Portfolio, where that such Holder would otherwise have been
          entitled to receive less than $1,000 of any such security.
              

             
          SECTION 3.16.  NO CONSENT TO ASSUMPTION.
              

             
                    Each Holder of a Security, 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 Purchase Contract by the Company, its trustee in
          bankruptcy, receiver, liquidator or a person or entity performing
          similar functions, 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.

                    A payment of interest on any Debt Securities or
          distribution with respect to the appropriate Applicable Ownership
          Interest in the Treasury Portfolio, as the case may be, which is
          paid on any Payment Date shall, subject to receipt thereof by the
          Agent from the Collateral Agent as provided by the terms of the
          Pledge Agreement, be paid to the Person in whose name the Income
          PRIDES Certificate (or one or more Predecessor Income PRIDES
          Certificates) of which such Debt Securities or the appropriate
          Applicable Ownership Interest in the Treasury Portfolio, as the
          case may be, are a part is registered at the close of business on
          the Record Date for such Payment Date.
              

             
                    Each Income PRIDES Certificate evidencing Debt
          Securities delivered under this Agreement upon registration of
          transfer of or in exchange for or in lieu of any other Income
          PRIDES Certificate shall carry the rights to payment of interest
          accrued and unpaid, and to accrue interest, which is carried by
          the Debt Securities underlying such other Income PRIDES
          Certificate.
              

             
                    In the case of any Income PRIDES with respect to which
          Cash Settlement of the underlying applicable portion of the
          Purchase Contract is effected on the Business Day immediately
          preceding the applicable Purchase Contract Settlement Date
          pursuant to prior notice, or with respect to which Early
          Settlement of the underlying Purchase Contract is effected on an
          Early Settlement Date, or with respect to which 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, interest on the Debt Securities or distributions with
          respect to the appropriate Applicable Ownership Interest in the
          Treasury Portfolio, as the case may be, underlying such Income
          PRIDES otherwise payable on such Payment Date shall be payable on
          such Payment Date notwithstanding such Cash Settlement or Early
          Settlement or Collateral Substitution, and such interests shall,
          subject to receipt thereof by the Agent, be payable to the Person
          in whose name the Income PRIDES Certificate (or one or more
          Predecessor Income PRIDES Certificate) 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 Income PRIDES with respect to which Cash Settlement
          or Early Settlement of the underlying Purchase Contract is
          effected on the Business Day immediately preceding the applicable

          related Debt Securities or distributions with respect to the
          appropriate Applicable Ownership Interest in the Treasury

          such Income PRIDES; provided, however, that to the extent that
          such Holder continues to hold the separated Debt Securities that
          formerly comprised a part of such Holder's Income PRIDES, such
          Holder shall be entitled to receive the payment of interest on
          such separated Debt Securities.
              

             
                    The applicable Coupon Rate on the Series D Notes to be
          in effect on and after the First Purchase Contract Settlement
          Date will be reset on the third Business Day immediately

          SECTION 4.2.   NOTICE AND VOTING.
              

             
                    Under and subject to the terms of the Pledge Agreement,
          the Agent will be entitled to exercise the voting and any other
          consensual rights pertaining to the Debt Securities pledged with
          the Collateral Agent but only to the extent instructed by the
          Holders as described below. Upon receipt of notice of any meeting
          at which holders of Debt Securities are entitled to vote or upon
          any solicitation of consents, waivers or proxies of holders of
          Debt Securities, the Agent shall, as soon as practicable
          thereafter, mail to the Holders of Income PRIDES 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
          Debt Securities entitled to vote) shall be entitled to instruct
          the Agent as to the exercise of the voting rights pertaining to
          the Debt Securities underlying their Income PRIDES and (c)
          stating the manner in which such instructions may be given. Upon
          the written request of the Holders of Income PRIDES 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 Debt Securities
          as to which any particular voting instructions are received. In
          the absence of specific instructions from the Holder of an Income
          PRIDES, the Agent shall abstain from voting the Debt Security
          underlying such Income PRIDES. The Company hereby agrees, if
          applicable, to solicit Holders of Income PRIDES to timely
          instruct the Agent in order to enable the Agent to vote such Debt
          Securities.
              

             
          SECTION 4.3.   TAX EVENT REDEMPTION.
              

             
                    Upon the occurrence of a Tax Event Redemption prior to
          the Second Purchase Contract Settlement Date, the Redemption
          Price payable on the Tax Event Redemption Date with respect to
          the Applicable Principal Amount of Debt Securities shall be
          delivered to the Collateral Agent in exchange for the Pledged
          Debt Securities.  Pursuant to the terms of the Pledge Agreement,
          the Collateral Agent will apply an amount equal to the Redemption
          Amount of such Redemption Price to purchase on behalf of the
          Holders of Income PRIDES the Treasury Portfolio and promptly
          remit the remaining portion of such Redemption Price to the Agent
          for payment to the Holders of such Income PRIDES. The Treasury
          Portfolio will be substituted for the outstanding Pledged Debt
          Securities, and will be held by the Collateral Agent in
          accordance with the terms of the Pledge Agreement to secure the
          obligation of each Holder of an Income PRIDES to purchase the
          Common Stock of the Company on the applicable Purchase Contract
          Settlement Date under the Purchase Contract constituting a part
          of such Income PRIDES. Following the occurrence of a Tax Event
          Redemption prior to the Second Purchase Contract Settlement Date,
          the Holders of Income PRIDES and the Collateral Agent shall have
          such security interests, rights and obligations with respect to
          the Treasury Portfolio as the Holder of Income PRIDES and the
          Collateral Agent had in respect of the Debt Securities subject to
          the Pledge thereof as provided in Sections 2, 3, 4, 5 and 6 of
          the Pledge Agreement, and any reference herein to the Debt
          Securities shall be deemed to be reference to such Treasury
          Portfolio. The Company may cause to be made in any Income PRIDES
          Certificates thereafter to be issued such change in phraseology
          and form (but not in substance) as may be appropriate to reflect
          the liquidation of the Trust and the substitution of the Treasury
          Portfolio for Debt Securities as collateral.
              

             
          SECTION 4.4.   CONSENT TO TREATMENT FOR TAX PURPOSES.
              

             
                    Each Holder of an Income PRIDES or a Growth PRIDES, by
          its acceptance thereof, covenants and agrees to treat itself as
          the owner, for United States federal, state and local income and
          franchise tax purposes, of (i) the related Debt Securities or the
          appropriate Applicable Ownership Interest in the Treasury
          Portfolio, in the case of the Income PRIDES, or (ii) the Treasury
          Securities, in the case of the Growth PRIDES.  Each Holder of an
          Income PRIDES, by its acceptance thereof, further covenants and
          agrees to treat the Debt Securities as indebtedness of the
          Company for United States federal, state and local income and
          franchise tax purposes.

                                THE PURCHASE CONTRACTS
              

             
          SECTION 5.1.   PURCHASE OF SHARES OF COMMON STOCK.
              

             
                    Each Purchase Contract shall, unless a Termination
          Event or an Early Settlement in accordance with Section 5.9
          hereof has occurred, obligate the Holder of the related Security
          to purchase, and the Company to sell, on each of the First
          Purchase Contract Settlement Date and the Second Purchase
          Contract Settlement Date, for $25 in cash on each such date (the
          "Purchase Price"), a number of newly issued shares of Common
          Stock equal to the applicable Settlement Rate.  The "Settlement
          Rate" as determined with respect to a Purchase Contract
          Settlement Date is equal to (a) if the Applicable Market Value
          (as defined below) is equal to or greater than $ 49.19 (the
          "Threshold Appreciation Price"), .5082  shares of Common Stock
          per Purchase Contract, (b) if the Applicable Market Value is less
          than the Threshold Appreciation Price, but is greater than
          $41.6875, the number of shares of Common Stock equal to $25
          divided by the Applicable Market Value and (c) if the Applicable
          Market Value is less than or equal to $ 41.6875, .5997 shares of
          Common Stock per 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 5.10, no fractional shares of Common Stock
          will be issued upon settlement of Purchase Contracts.
              

             
                    The "Applicable Market Value" with respect to a
          Purchase Contract Settlement Date means the average of the
          Closing Price per share of Common Stock on each of the twenty
          consecutive Trading Days ending on the third Trading Day
          immediately preceding such Purchase Contract Settlement 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, 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
          exchange or association or over-the-counter market at the close
          of business that is the primary market for the trading of the
          Common Stock.
              

             
                    Each Holder of an Income PRIDES or a Growth PRIDES, by
          its acceptance thereof, irrevocably authorizes the Agent to enter
          into and perform the related 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 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 Debt Securities, the Treasury
          Portfolio or the Treasury Securities pursuant to the Pledge
          Agreement.  Each Holder of an Income PRIDES or a Growth PRIDES,
          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 principal of and interest on Debt Securities or
          the Proceeds of the Treasury Securities or Applicable Ownership
          Interest in the Treasury Portfolio on a Purchase Contract
          Settlement Date shall be paid by the Collateral Agent to the
          Company in satisfaction of such Holder's obligations under such
          Purchase Contract and such Holder shall acquire no right, title
          or interest in such payments.
              

             
                    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 Purchase Contract underlying such Certificate and
          the Pledge Agreement; and the transferor shall be released from
          the obligations under this Agreement, the 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.
              

             
                    Subject to Section 5.3 herein, the Company shall pay,
          on each Payment Date, the Contract Adjustment Payments payable in
          respect of each Purchase Contract to the Person in whose name a
          Certificate (or one or more Predecessor Certificates) is
          registered at the close of business on the Record Date next
          preceding such Payment Date. The Contract Adjustment Payments
          will be payable at the office of the Agent in The City of 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 Income
          PRIDES Register or Growth PRIDES Register.
              

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

             
                    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 Income PRIDES) any other Certificate shall
          carry the rights to Contract Adjustment Payments accrued and
          unpaid, and to accrue Contract Adjustment Payments, which were
          carried by the Purchase Contracts underlying such other
          Certificates.
              

             
                    Subject to Section 5.9, in the case of any Security
          with respect to which Early Settlement of the underlying Purchase
          Contract is effected on an Early Settlement Date that is after
          any Record Date and on or prior to the next succeeding Payment
          Date, Contract Adjustment Payments, if any, otherwise payable on
          such Payment Date shall be payable on such Payment Date
          notwithstanding such Early Settlement, and such Contract
          Adjustment Payments shall be paid to the Person in whose name the
          Certificate evidencing such Security (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 Security with
          respect to which Early Settlement of the underlying Purchase
          Contract is effected on an Early Settlement Date, Contract
          Adjustment Payments that would otherwise be payable after the
          Early Settlement Date with respect to such Purchase Contract
          shall not be payable.
              

             
                    The Company's obligations with respect to Contract
          Adjustment Payments, will be subordinated and junior in right of
          payment to the Company's obligations under any Senior
          Indebtedness.
              

             
          SECTION 5.3.   DEFERRAL OF PAYMENT DATES FOR CONTRACT ADJUSTMENT
                         PAYMENTS.
              

             
                    The Company shall have the right to defer the payment
          of any or all of the Contract Adjustment Payments otherwise
          payable on any Payment Date to a date no later than the Purchase
          Contract Settlement Date next succeeding the date such deferral
          commences, but only if the Company shall give the Holders and the
          Agent written notice of its election to defer such 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 Securities, but
          in any event not less than one Business Day prior to such Record
          Date.  In connection with any Contract Adjustment Payments so
          deferred, additional Contract Adjustment Payments thereon will
          accrue at the rate of 9.75% per annum (computed on the basis of
          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 together with the
          accrued additional Contract Adjustment Payments thereon, being
          referred to herein as the "Deferred Contract Adjustment
          Payments"). Deferred Contract Adjustment Payments shall be due on
          the next succeeding Payment Date except to the extent that
          payment is deferred pursuant to this Section. No Contract
          Adjustment Payments may be deferred to a date that is after the
          Purchase Contract Settlement Date next succeeding the date such
          deferral commences. If the Purchase Contracts are terminated upon
          the occurrence of a Termination Event, the Holder's right to
          receive Contract Adjustment Payments and Deferred Contract
          Adjustment Payments will terminate.
              

             
                    In the event that the Company elects to defer the
          payment of Contract Adjustment Payments on the Purchase Contracts
          until the next succeeding Purchase Contract Settlement Date, each
          Holder will receive on such Purchase Contract Settlement Date, in
          lieu of a cash payment, a number of shares of Common Stock (in
          addition to a number of shares of Common Stock equal to the
          Settlement Rate) equal to (x) the aggregate amount of Deferred
          Contract Adjustment Payments payable to such Holder divided by
          (y) the Applicable Market Value.
              

             
                    No fractional shares of Common Stock will be issued by
          the Company with respect to the payment of Deferred Contract
          Adjustment Payments on a Purchase Contract Settlement Date. In
          lieu of fractional shares otherwise issuable with respect to such
          payment of Deferred Contract Adjustment Payments, the Holder will
          be entitled to receive an amount in cash as provided in Section
          5.10.
              

             
                    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 capital stock or make
          guarantee payments with respect to the foregoing (other than (i)
          purchases or acquisitions of capital stock of the Company in
          connection with the satisfaction by the Company of its
          obligations under any employee or agent benefit plans or the
          satisfaction by the Company of its obligations pursuant to any
          contract or security outstanding on the date of such event
          requiring the Company to purchase its capital stock, (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 the Company's capital stock pursuant to
          the conversion or exchange provisions of the Company's capital
          stock or the security being converted or exchanged, (iv)
          dividends or distributions in capital stock of the Company (or
          rights to acquire capital stock) or repurchases or redemptions of
          capital stock solely from the issuance or exchange of capital
          stock or (v) redemptions or repurchases of any rights outstanding
          under a shareholder rights plan).

          
    
   
          SECTION 5.4.   PAYMENT OF PURCHASE PRICE.
              

             
                    (a) (i) Unless a Tax Event Redemption has occurred or a
               Holder settles the underlying Purchase Contract through the
               early delivery of cash to the Purchase Contract Agent in the
               manner described in Section 5.9, each Holder of an Income
               PRIDES must notify the Agent by use of a notice in
               substantially the form of Exhibit C hereto of its intention
               to pay in cash ("Cash Settlement") the Purchase Price for
               the shares of Common Stock to be purchased pursuant to the
               applicable portion of a Purchase Contract on a Purchase
               Contract Settlement Date. Such notice shall be made on or
               prior to 5:00 p.m., New York City time, on the fifth
               Business Day immediately preceding the applicable Purchase
               Contract Settlement 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.
              

             
                         (ii) A Holder of an Income PRIDES 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 Business Day immediately preceding the applicable
               Purchase Contract Settlement Date in lawful money of the
               United States by certified or cashiers' check or wire
               transfer, in each case in immediately available funds
               payable to or upon the order of the Company. Any cash
               received by the Collateral Agent will be invested promptly
               by the Collateral Agent in Permitted Investments and paid to
               the Company on the applicable Purchase Contract Settlement
               Date in settlement of the applicable portion of the Purchase
               Contract in accordance with the terms of this Agreement and
               the Pledge Agreement. Any funds received by the Collateral
               Agent in respect of the investment earnings from the
               investment in such Permitted Investments, will be
               distributed to the Agent when received for payment to the
               Holder.
              

             
                         (iii) If a Holder of an Income PRIDES fails to
               notify the Agent of its intention to make a Cash Settlement
               in accordance with paragraph (a)(i) above, such failure
               shall constitute a default under the related Purchase
               Contract and the Holder shall be deemed to have consented to
               the disposition of the applicable pledged Debt Securities
               (which shall be Series D Notes in connection with the First
               Purchase Contract Settlement Date and Series E Notes in
               connection with the Second Purchase Contract Settlement
               Date) pursuant to the remarketing as described in paragraph
               (b) below. If a Holder of an Income PRIDES does notify the
               Agent as provided in paragraph (a)(i) above of its intention
               to pay the Purchase Price in cash, but fails to make such
               payment as required by paragraph (a)(ii) above, such failure
               shall also constitute a default; however, the Debt
               Securities of such a Holder will not be remarketed but
               instead the Collateral Agent, for the benefit of the
               Company, will exercise its rights as a secured party with
               respect to such Debt Securities, including those rights
               specified in paragraph (c) below.
              

             
                    (b)  In order to dispose of the applicable Debt
               Securities (which shall be Series D Notes in connection with
               the First Purchase Contract Settlement Date and Series E
               Notes in connection with the Second Purchase Contract
               Settlement Date) of Income PRIDES Holders who have not
               notified the Agent of their intention to effect a Cash
               Settlement with respect to a Purchase Contract Settlement
               Date as provided in paragraph (a)(i) above, the Company
               shall engage one or more nationally recognized investment
               banking firms (the "Remarketing Agent") pursuant to a
               Remarketing Agreement to sell such Debt Securities. In order
               to facilitate the remarketing, the Agent shall notify the
               Remarketing Agent, by 10:00 a.m., New York City time, on the
               fourth Business Day immediately preceding such Purchase
               Contract Settlement Date, of the aggregate number of Debt
               Securities to be remarketed. Concurrently, the Collateral
               Agent, pursuant to the terms of the Pledge Agreement, will
               present for remarketing such Debt Securities to the
               Remarketing Agent. Upon receipt of such notice from the
               Agent and such Debt Securities from the Collateral Agent,
               the Remarketing Agent will, on the third Business Day
               immediately preceding such Purchase Contract Settlement
               Date, use its reasonable efforts to remarket such Debt
               Securities on such date at a price of approximately 100.5%
               (but not less than 100%) of the aggregate principal amount
               of such Debt Securities, plus accrued and unpaid interest,
               if any, thereon. After deducting as the remarketing fee
               ("Remarketing Fee") an amount not exceeding 25 basis points
               (.25%) of the aggregate principal amount of the remarketed
               Debt Securities of such series from any amount of such
               proceeds in excess of the aggregate principal amount of such
               remarketed Debt Securities of such series plus accrued and
               unpaid interest, if any, then the Remarketing Agent will
               remit the remaining portion of the proceeds from such
               remarketing to the Collateral Agent. Such portion of the
               proceeds, equal to the aggregate principal amount of such
               Debt Securities, will automatically be applied by the
               Collateral Agent, in accordance with the Pledge Agreement to
               satisfy in full such Income PRIDES holders' obligations to
               pay the Purchase Price for the Common Stock under the
               applicable portions of the related Purchase Contracts on
               such Purchase Contract Settlement Date. Any proceeds in
               excess of those required to pay the Purchase Price and the
               Remarketing Fee will be remitted to the Agent for payment to
               the Holders of the related Income PRIDES. Income PRIDES
               Holders whose Debt Securities are so remarketed will not
               otherwise be responsible for the payment of any Remarketing
               Fee in connection therewith. If such a remarketing does not
               occur because a condition precedent to such remarketing
               shall not have been fulfilled, or if in spite of using its
               reasonable efforts, the Remarketing Agent cannot remarket
               the related Debt Securities of such Holders of Income PRIDES
               at a price not less than 100% of the aggregate principal
               amount of such Debt Securities plus accrued and unpaid
               interest, if any, the remarketing will be deemed to have
               failed (a "Failed Remarketing") and, in accordance with the
               terms of the Pledge Agreement the Collateral Agent for the
               benefit of the Company will exercise its rights as a secured
               party with respect to such Debt Securities, including those
               actions specified in paragraph (c) below; provided, that if
               upon a Failed Remarketing the Collateral Agent exercises
               such rights for the benefit of the Company with respect to
               such Debt Securities, any accrued and unpaid interest on
               such Debt Securities will become payable by the Company to
               the Agent for payment to the Holder of the Income PRIDES to
               which such Debt Securities relates. Such payment will be
               made by the Company on or prior to 11 a.m. New York City
               time on the applicable Purchase Contract Settlement Date in
               lawful money of the United States by certified or cashiers'
               check or wire transfer in immediately available funds
               payable to or upon the order of the Agent. The Company will
               cause a notice of such Failed Remarketing to be published on
               the second Business Day immediately preceding such Purchase
               Contract Settlement Date in an Authorized Newspaper.
              

             
                    (c)  With respect to any Debt Securities beneficially
               owned by Holders who have elected Cash Settlement but failed
               to deliver cash as required in (a)(ii) above, or with
               respect to Debt Securities which are subject to a 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 paragraph
               (h) below, may, among other things, (i) retain such Debt
               Securities in full satisfaction of the Holders  obligations
               under the applicable portions of the Purchase Contracts or
               (ii) sell such Debt Securities in one or more public or
               private sales and apply the proceeds of such sale in full
               satisfaction of the Holders  obligations under the
               applicable portions of the Purchase Contracts.
              

             
                    (d) (i) Unless a Holder of Growth PRIDES or, if a Tax
               Event Redemption has occurred, Income PRIDES settles the
               underlying Purchase Contract through the early delivery of
               cash to the Purchase Contract Agent in the manner described
               in Section 5.9, each Holder of a Growth PRIDES or, if a Tax
               Event Redemption has occurred, Income PRIDES must notify the
               Agent by use of a notice in substantially the form of
               Exhibit C hereto of its intention to pay in cash the
               Purchase Price for the shares of Common Stock to be
               purchased pursuant to the applicable portion of a Purchase
               Contract on or prior to 5:00 p.m., New York City time, on
               the second Business Day immediately preceding the applicable
               Purchase Contract Settlement Date.
              

             
                         (ii) A Holder of a Growth PRIDES or, if a Tax
               Event Redemption has occurred, Income PRIDES who has so
               notified the Agent of its intention to make a Cash
               Settlement in accordance with paragraph (d)(i) above is
               required to pay the Purchase Price to the Collateral Agent
               prior to 11:00 a.m., New York City time, on the Business Day
               immediately preceding the applicable Purchase Contract
               Settlement Date in lawful money of the United States by
               certified or cashiers' check or wire transfer, in each case
               in immediately available funds payable to or upon the order
               of the Company. Any cash received by the Collateral Agent
               will be invested promptly by the Collateral Agent in
               Permitted Investments and paid to the Company on the
               applicable Purchase Contract Settlement Date in settlement
               of the applicable portion of the Purchase Contract in
               accordance with the terms of this Agreement and the Pledge
               Agreement. Any funds received by the Collateral Agent in
               respect of the investment earnings from the investment in
               such Permitted Investments will be distributed to the Agent
               when received for payment to the Holder.
              

             
                         (iii) If a Holder of a Growth PRIDES or, if a Tax
               Event Redemption has occured, an Income PRIDES, fails to
               notify the Agent of its intention to make a Cash Settlement
               in accordance with paragraph (d)(i) above, or if a Holder of
               a Growth PRIDES or an Income PRIDES (if a Tax Event
               Redemption has occurred) does notify the Agent as provided
               in paragraph (d)(i) above of its intention to pay the
               Purchase Price in cash, but fails to make such payment as
               required by paragraph (d)(ii) above, then such failure shall
               constitute a default under the related Purchase Contract and
               upon the maturity of the Pledged Treasury Securities or the
               appropriate Applicable Ownership Interest in the Treasury
               Portfolio, as the case may be, held by the Collateral Agent
               on the Business Day immediately prior to the applicable
               Purchase Contract Settlement Date, the principal amount of
               the Treasury Securities or the appropriate Applicable
               Ownership Interest in the Treasury Portfolio, as the case
               may be, received by the Collateral Agent will be invested
               promptly in overnight Permitted Investments.  On the
               applicable Purchase Contract Settlement Date an amount equal
               to the Purchase Price will be remitted to the Company as
               payment thereof without receiving any instructions from the
               Holder. In the event the sum of the proceeds from the
               related Pledged Treasury Securities or the appropriate
               Applicable Ownership Interest in the Treasury Portfolio, as
               the case may be, and the investment earnings earned from
               such investments is in excess of the aggregate Purchase
               Price of the applicable portions of the Purchase Contracts
               being settled thereby, the Collateral Agent will distribute
               such excess to the Agent for the benefit of the Holder of
               the related Growth PRIDES or Income PRIDES when received.
              

             
                    (e)  Any distribution to Holders of excess funds and
               interest described 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, by check mailed to
               the address of the Person entitled thereto at such address
               as it appears on the Register.
              

             
                    (f)  Unless a Holder settles the underlying Purchase
               Contract through the early delivery of cash to the
               Collateral Agent with respect to a Purchase Contract
               Settlement Date in the manner described herein, the Company
               shall not be obligated to issue any shares of Common Stock
               in respect of the relevant portion of the Purchase Contract
               or deliver any certificate therefor to the Holder unless it
               shall have received payment in full of the Purchase Price
               for the shares of Common Stock to be purchased thereunder in
               the manner herein set forth.
              

             
                    (g)  Upon Cash Settlement with respect to the
               applicable portion of any Purchase Contract, (i) the
               Collateral Agent will, in accordance with the terms of the
               Pledge Agreement, cause the corresponding Pledged Debt
               Securities or appropriate Applicable Ownership Interest in
               the Treasury Portfolio, as the case may be, or the Pledged
               Treasury Securities underlying the relevant Security to be
               released from the Pledge by the Collateral Agent free and
               clear of any security interest of the Company and
               transferred to the Agent for delivery to the Holder thereof
               or its designee as soon as practicable and (ii) subject to
               the receipt thereof from the Collateral Agent, the Agent
               shall, by book-entry transfer, or other appropriate
               procedures, in accordance with instructions provided by the
               Holder thereof, transfer such Debt Securities or the
               appropriate Applicable Ownership Interest in the Treasury
               Portfolio, as the case may be, or such Treasury Securities
               (or, if no such instructions are given to the Agent by the
               Holder, the Agent shall hold such Debt Securities or the
               Treasury Portfolio, as the case may be, or such Treasury
               Securities, and any distribution thereon, in the name of the
               Agent or its nominee in trust for the benefit of such
               Holder).
              

             
                    (h)  The obligations of the Holders to pay the Purchase
               Price on each Purchase Contract Settlement Date are
               non-recourse obligations and are payable solely out of any
               Cash Settlement or the proceeds of any Collateral pledged to
               secure the obligations of the Holders with respect to such
               Purchase Price, and in no event will Holders be liable for
               any deficiency between the proceeds of Collateral
               disposition and the Purchase Price.  A default by a Holder
               in the performance of its obligations under a Purchase
               Contract in connection with the First Purchase Contract
               Settlement Date shall not in itself be a default in the
               performance of its obligations under such Purchase Contract
               in connection with the Second Purchase Contract Settlement
               Date (except in connection with Early Settlement).
              

             
          SECTION 5.5.   ISSUANCE OF SHARES OF COMMON STOCK.
              

             
                    Unless a Termination Event or an Early Settlement shall
          have occurred, on a Purchase Contract Settlement Date, upon its
          receipt of payment in full of the applicable Purchase Price for
          shares of Common Stock purchased by the Holders pursuant to the
          foregoing provisions of this Article and subject to Section
          5.6(b), the Company shall issue and deposit with the Agent, for
          the benefit of the Holders of the Outstanding Securities, one or
          more certificates 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 for shares of Common
          Stock, together with any dividends or distributions for which
          both a record date and payment date for such dividend or
          distribution has occurred after the Purchase Contract Settlement
          Date, being hereinafter referred to as the "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 a Purchase Contract Settlement 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 representing that number of whole
          shares of Common Stock which such Holder is entitled to receive
          pursuant to the provisions of this Article Five (after taking
          into account all Securities then held by such Holder) together
          with cash in lieu of fractional shares as provided in Section
          5.10 and any dividends or distributions with respect to such
          shares constituting part of the Purchase Contract Settlement
          Fund, but without any interest thereon, and the Certificate so
          surrendered shall forthwith be canceled. 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 Purchase Contract are to be registered to a Person other than
          the Person in whose name the Certificate evidencing such 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 the Certificate
          evidencing such Purchase Contract 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.
              

             
                    (1)  In case the Company shall pay or make a
               dividend or other distribution on the Common Stock in
               Common Stock, the Settlement Rate, 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 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 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 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 will not pay any dividend or make any
               distribution on shares of Common Stock held in the
               treasury of the Company.
              

             
                    (2)  In case the Company shall issue rights,
               options or warrants to all holders of its Common Stock
               that are not available on an equivalent basis to
               Holders of the Securities upon settlement of the
               Purchase Contracts underlying such Securities entitling
               such holders of the Common Stock, for a period expiring
               within 45 days after the record date for the
               determination of stockholders entitled to receive such
               rights, options or warrants, 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 plan, including such a plan that provides
               for purchases of Common Stock by non-shareholders), the
               Settlement Rate, 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, 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 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 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)  In case outstanding shares of Common Stock
               shall be subdivided or split into a greater number of
               shares of Common Stock, the Settlement Rate, 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 Common Stock shall each be
               combined into a smaller number of shares of Common
               Stock, the Settlement Rate, 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)  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 or distribution referred to in
               paragraph (1) of this Section), the Settlement Rate,
               shall be adjusted so that the same shall equal the rate
               determined by dividing the Settlement Rate 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 of which the
               numerator 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 filed with the Agent) of the portion
               of the assets or evidences of indebtedness so
               distributed applicable to one share of Common Stock and
               the denominator 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.
              

             
                    (5)  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 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, shall be increased
               so that the same shall equal the rate determined by
               dividing the Settlement Rate 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 (i) 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 (ii) the
               denominator of which shall be equal to the Current
               Market Price per share of the Common Stock on such date
               for determination.
              

             
                    (6)  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 of the
               expiration of such tender or exchange offer, of
               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) on 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, shall be adjusted so that the same shall equal
               the rate determined by dividing the Settlement Rate
               immediately prior to the close of business on the date
               of the Expiration Time by a fraction (i) the numerator
               of which shall be equal to (A) 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) on the Expiration Time less (B) 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 (ii) the denominator of which
               shall be equal to the product of (A) the Current Market
               Price per share of the Common Stock as of the
               Expiration Time and (B) 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)  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 (a) 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 (b) a
               subdivision, split or combination, as the case may be,
               of the number of shares of Common Stock outstanding
               immediately 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)  The "Current Market Price" per share of
               Common Stock on any day means the average of the daily
               Closing Prices for the five consecutive Trading Days
               selected by the Company commencing not more than 30
               Trading Days before, and ending not later than, the
               earlier of the day in question and the day before the
               "ex date" with respect to the issuance or distribution
               requiring such computation. 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
               such exchange or in such market without the right to
               receive such issuance or distribution.
              

             
                    (9)  All adjustments to the Settlement Rate, 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 shall be required
               unless such adjustment would require an increase or
               decrease of at least one percent therein; provided,
               however, 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 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 (a), (b) or
               (c) of the definition of Settlement Rate in Section 5.1
               will apply on the Purchase Contract Settlement Date.
               Such adjustment shall be made by multiplying the
               Applicable Market Value by a fraction of which the
               numerator shall be the Settlement Rate 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 shall be the Settlement Rate
               immediately before such adjustment; provided, however,
               that if such adjustment to the Settlement Rate is
               required to be made pursuant to the occurrence of any
               of the events contemplated by paragraph (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.
              

             
                    (10) The Company may make such increases in the
               Settlement Rate, in addition to those required by this
               Section, as it considers to be advisable in order to
               avoid or diminish the effect of 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 (i) 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), (ii) any sale,
               transfer, lease or conveyance to another Person of the
               property of the Company as an entirety or substantially as
               an entirety, (iii) any statutory exchange of securities of
               the Company with another Person (other than in connection
               with a merger or acquisition) or (iv) 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"), the Settlement
               Rate will be adjusted to provide that each Holder of
               Securities will receive on the applicable Purchase Contract
               Settlement Date with respect to each Purchase Contract
               forming a part thereof, the kind and amount of securities,
               cash and other property receivable upon such Reorganization
               Event (without any interest thereon, and without any right
               to dividends or distribution thereon which have a record
               date that is prior to such Purchase Contract Settlement
               Date) by a Holder of the number of shares of Common Stock
               issuable on account of each Purchase Contract if the
               Purchase Contract Settlement Date had occurred immediately
               prior to such Reorganization Event assuming such Holder of
               Common Stock 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 such Holder failed to
               exercise its 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 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). 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 Holders of each Outstanding
               Security 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 is adjusted as herein
               provided, the Company shall:
              

             
                    (i)  forthwith compute the Settlement Rate in
               accordance with Section 5.6 and prepare and transmit to
               the Agent a Company Certificate setting forth the
               Settlement Rate, the method of calculation thereof in
               reasonable detail, and the facts requiring such
               adjustment and upon which such adjustment is based; and
              

             
                    (ii) within 10 Business Days following the
               occurrence of an event that requires an adjustment to
               the Settlement Rate 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 Securities of the
               occurrence of such event and a statement in reasonable
               detail setting forth the method by which the adjustment
               to the Settlement Rate was determined and setting forth
               the adjusted Settlement Rate.
              

             
                    (b)  The Agent shall not at any time be under any duty
               or responsibility to any Holder of Securities to determine
               whether any facts exist which may require any adjustment of
               the Settlement Rate, 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 the time be
               issued or delivered with respect to any Purchase Contract;
               and the 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 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 Purchase Contracts and all obligations and rights
          of the Company and the Holders thereunder, including, without
          limitation, the rights of the Holders to receive and the
          obligation of the Company to pay any Contract Adjustment Payments
          or 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 Second Purchase Contract Settlement Date, a
          Termination Event shall have occurred. Upon and after the
          occurrence of a Termination Event, the Securities shall
          thereafter represent the right to receive the Debt Securities or
          the appropriate Applicable Ownership Interest in the Treasury
          Portfolio, as the case may be, forming a part of such Securities
          in the case of Income PRIDES, or Treasury Securities in the case
          of Growth PRIDES, 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 thereof 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)  A holder of Income PRIDES may settle the related
               Purchase Contracts in their entirety on or prior to the
               fifth Business Day immediately preceding either Purchase
               Contract Settlement Date in the manner described herein, but
               only in integral multiples of 40 Income PRIDES; provided,
               however, that such settlements may not be made during the
               period from the fifth Business Day immediately preceding the
               First Purchase Contract Settlement Date through the First
               Purchase Contract Settlement Date, and provided, further, if
               a Tax Event Redemption has occurred prior to such Purchase
               Contract Settlement Date and the Treasury Portfolio has
               become a component of the Income PRIDES, holders of Income
               PRIDES may settle early only in integral multiples of
               1,600,000 Income PRIDES at any time on or prior to the
               second Business Day immediately preceding such Purchase
               Contract Settlement Date (but not during the period two
               Business Days immediately preceding the First Purchase
               Contract Settlement Date through the First Purchase Contract
               Settlement Date). A holder of Growth PRIDES may settle the
               related Purchase Contracts in their entirety on or prior to
               the second Business Day immediately preceding each Purchase
               Contract Settlement Date in the manner described herein (in
               either case, an Early Settlement but only in integral
               multiples of 40 Growth PRIDES). Upon Early Settlement, (i)
               the holder's rights to receive Deferred Contract Adjustment
               Payments on the Purchase Contracts being settled will be
               forfeited, (ii) the holder's right to receive additional
               Contract Adjustment Payments in respect of such Purchase
               Contracts will terminate and (iii) no adjustment will be
               made to or for the holder on account of Deferred Contract
               Adjustment Payments, or any amount accrued in respect of
               Contract Adjustment Payments.  In order to exercise the
               right to effect any such early settlement ("Early
               Settlement") with respect to any Purchase Contracts, the
               Holder of the Certificate evidencing Securities 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 the sum of (i)(A)
               $50 times the number of Purchase Contracts being settled if
               settled on or prior to the fifth Business Day immediately
               preceding the First Purchase Contract Settlement Date or (B)
               $25 times the number of Purchase Contracts being settled if
               settled after the First Purchase Contract Settlement Date,
               plus, in either case, (ii) if such delivery is made with
               respect to any 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
               payable on such Payment Date with respect to such Purchase
               Contracts. Except as provided in the immediately preceding
               sentence and subject to the second to last paragraph of
               Section 5.2, no payment or adjustment shall be made upon
               Early Settlement of any Purchase Contract on account of any
               Contract Adjustment Payments accrued on such Purchase
               Contract or on account of any dividends on the Common Stock
               issued upon such Early Settlement. In order for any of the
               foregoing requirements to be considered satisfied or
               effective with respect to a Purchase Contract underlying any
               Security on or by a particular Business Day, such
               requirement must be met at or prior to 5:00 p.m., New York
               City time, on such Business Day; the first Business Day on
               which all of the foregoing requirements have been satisfied
               by 5:00 p.m., New York City time.shall be the "Early
               Settlement Date" with respect to such Security. 
              

             
                    (b)  Upon Early Settlement of Purchase Contracts by a
               Holder of the related Securities, the Company shall issue,
               and the Holder shall be entitled to receive (i) if settled
               prior to the First Purchase Contract Settlement Date, 1.0164
               newly issued shares of Common Stock per Income PRIDES or
               Growth PRIDES (the "First Early Settlement Rate") or (ii) if
               settled after the First Purchase Contract Settlement Date
               and before the Second Purchase Contract Settlement Date,
               .5082 newly issued shares of Common stock per Income PRIDES
               or Growth PRIDES (the "Second Early Settlement Rate"),
               (regardless in either case of the market price of the Common
               Stock on the date of such Early Settlement); provided,
               however, that upon the Early Settlement of the Purchase
               Contracts, the Holder of such related Securities will
               forfeit the right to receive any Deferred Contract
               Adjustment Payments. 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 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 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 5.10.
              

             
                    (c)  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
               Purchase Contracts to be issued and delivered, and (ii) the
               related Debt Securities or the appropriate Applicable
               Ownership Interest in the Treasury Portfolio, in the case of
               Income PRIDES, or the related Treasury Securities, in the
               case of Growth PRIDES, 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.
              

             
                    (d)  Upon Early Settlement of any Purchase Contracts,
               and subject to receipt of shares of Common Stock from the
               Company and the Debt Securities, the appropriate Applicable
               Ownership Interest in the Treasury Portfolio or 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 Securities, (i)
               transfer to the Holder the Debt Securities, Treasury
               Portfolio or Treasury Securities, as the case may be,
               forming a part of such Securities, and (ii) deliver to the
               Holder a certificate or certificates 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 5.10.
              

             
                    (e)  In the event that Early Settlement is effected
               with respect to Purchase Contracts underlying less than all
               the Securities evidenced by a Certificate, upon such Early
               Settlement the Company shall execute and the Agent shall
               authenticate, countersign and deliver to the Holder thereof,
               at the expense of the Company, a Certificate evidencing the
               Securities as to which Early Settlement was not effected.
              

             
          SECTION 5.10.  NO FRACTIONAL SHARES.
              

             
                    No fractional shares or scrip representing fractional
          shares of Common Stock shall be issued or delivered upon
          settlement on a Purchase Contract Settlement Date or upon Early
          Settlement of any Purchase Contracts. If Certificates evidencing
          more than one 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
          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 Purchase
          Contracts on a Purchase Contract Settlement Date or upon Early
          Settlement, the Company, through the Agent, shall make a cash
          payment in respect of such fractional interest in an amount equal
          to the value of such fractional shares 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 5.10 in a timely manner.
              

             
          SECTION 5.11.  CHARGES AND TAXES.
              

             
                    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 Purchase Contracts and in
          payment of any Deferred Contract Adjustment Payments; provided,
          however, 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 a Security 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 Securities 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
          Certificates unless or 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.
              

             
                                      ARTICLE VI

                                       REMEDIES
              

             
          SECTION 6.1.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE CONTRACT
                         ADJUSTMENT PAYMENTS AND TO PURCHASE COMMON STOCK.
              

             
                    The Holder of any Income PRIDES or Growth PRIDES 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, the prepayment of Contract Adjustment Payments
          pursuant to Section 5.9(a) and to the forfeiture of any Deferred
          Contract Adjustment Payments upon Early Settlement pursuant to
          Section 5.9(b) or upon the occurrence of a Termination Event), to
          receive payment of each installment of the Contract Adjustment
          Payments with respect to the Purchase Contract constituting a
          part of such Security on the respective Payment Date for such
          Security and to purchase Common Stock pursuant to such Purchase
          Contract and, in each such case, to institute suit for the
          enforcement of any such payment and right to purchase Common
          Stock, and such rights 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 the last paragraph of Section 3.10, 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
          Income PRIDES or Growth PRIDES, by its acceptance of such Income
          PRIDES or Growth PRIDES 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

          such court may in its discretion assess reasonable costs,
          including reasonable attorneys' fees, against any party litigant
          in such suit, having due regard to the merits and good faith of
          the claims or defenses made by such party litigant; 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,

                    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 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 and covenants that it will not
          hinder, delay or impede the execution of any power herein granted
          to the Agent or the Holders, but will suffer and permit the
          execution of every such power as though no such law had been
          enacted.
              

             
                                     ARTICLE VII

                                      THE AGENT
              

             
          SECTION 7.1.   CERTAIN DUTIES AND RESPONSIBILITIES.
              

             
                    (a)  Prior to a Default and after the curing or waiving
               of all such Defaults that may have occurred,
              

             
                         (1)  the Agent undertakes to perform, with respect
                    to the Securities, such duties and only such duties as
                    are specifically set forth in this Agreement and no
                    implied covenants or obligations shall be read into
                    this Agreement against the Agent; and
              

             
                         (2)  the Agent may, with respect to the
                    Securities, conclusively rely, as to the truth of the
                    statements and the correctness of the opinions
                    expressed therein, in the absence of bad faith on the
                    part of the Agent, upon certificates or opinions
                    furnished to the Agent and conforming to the
                    requirements of this Agreement; but in the case of any
                    certificates or opinions which by any provision hereof
                    are specifically required to be furnished to the Agent,
                    the Agent shall be under a duty to examine the same to
                    determine whether or not they conform to the
                    requirements of this Agreement.
              

             
                    (b)  No provision of this Agreement shall be construed
               to relieve the Agent from liability for its own negligent
               action, its own negligent failure to act, or its own wilful
               misconduct, except that
              

             
                         (1)  this Subsection shall not be construed to
                    limit the effect of Subsection (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
                    negligent in ascertaining the pertinent facts; and
              

             
                         (3)  no provision of this Agreement shall require
                    the Agent to expend or risk its own funds or otherwise
                    incur any financial liability in the performance of any
                    of its duties hereunder, or in the exercise of any of
                    its rights or powers.
              

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

             
                    (d)  The Agent is authorized to execute, deliver and
               perform the Pledge Agreement in its capacity as Agent and to
               grant the Pledge.  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 by the Agent pursuant to, such
               Pledge Agreement..
              

             
                    (e)  In case a Default has occurred (that has not been
               cured or waived), and is actually known by a Responsible
               Officer of the Agent, the Agent shall exercise such of the
               rights and powers vested in it by this Agreement, and use
               the same degree of care and skill in its exercise thereof,
               as a prudent person would exercise or use under the
               circumstances in the conduct of his or her own affairs.
              

             
                    (f)  At the request of the Company, the Agent is
               authorized to execute and deliver one or more Remarketing
               Agreements to, among other things, effectuate Section 5.4
              

             
          SECTION 7.2.   NOTICE OF DEFAULT.
              

             
                    Within 90 days after the occurrence of any Default
          hereunder of which a Responsible Officer of the Agent has actual
          knowledge, the Agent shall transmit by mail to the Company and
          the Holders of Securities, as their names and addresses appear in
          the Register, notice of such Default hereunder, unless such
          Default shall have been cured or waived; provided that, except
                                                   -------------
          for a default in any payment obligation hereunder, the Agent
          shall be protected in withholding such notice if and so long as
          the Responsible Officer of the Agent in good faith determines
          that the withholding of such notice is in the interests of the
          Holders of the Securities.
              

             
          SECTION 7.3.   CERTAIN RIGHTS OF AGENT.
              

             
                    Subject to the provisions of Section 7.1:
              

             
                    (a)  the Agent may rely and shall be protected in
               acting or refraining from acting upon any resolution,
               certificate, statement, instrument, opinion, report, notice,
               request, direction, consent, order, bond, debenture, note,
               other evidence of indebtedness or other paper or document
               believed by it to be genuine and to have been signed or
               presented by the proper party or parties;
              

             
                    (b)  any request or direction of the Company mentioned
               herein shall be sufficiently evidenced by a Company
               Certificate, Issuer Order or Issuer Request, and any
               resolution of the Board of Directors of the Company may be
               sufficiently evidenced by a Board Resolution;
              

             
                    (c)  whenever in the administration of this Agreement
               the Agent shall deem it desirable that a matter be proved or
               established prior to taking, suffering or omitting any
               action hereunder, the Agent (unless other evidence be herein
               specifically prescribed) may, in the absence of bad faith on
               its part, rely upon a Company Certificate;
              

             
                    (d)  the Agent may consult with counsel of its
               selection and the advice of such counsel or any Opinion of
               Counsel shall be full and complete authorization and
               protection in respect of any action taken, suffered or
               omitted by it hereunder in good faith and in reliance
               thereon;
              

             
                    (e)  the Agent shall not be bound to make any
               investigation into the facts or matters stated in any
               resolution, certificate, statement, instrument, opinion,
               report, notice, request, direction, consent, order, bond,
               debenture, note, other evidence of indebtedness or other
               paper or document, but the Agent, in its discretion, may
               make reasonable further inquiry or investigation into such
               facts or matters related to the execution, delivery and
               performance of the Purchase Contracts as it may see fit,
               and, if the Agent shall determine to make such further
               inquiry or investigation, it shall be given a reasonable
               opportunity to examine the books, records and premises of
               the Company, personally or by agent or attorney; and
              

             
                    (f)  the Agent may execute any of the powers hereunder
               or perform any duties hereunder either directly or by or
               through agents or attorneys or an Affiliate and the Agent
               shall not be responsible for any misconduct or negligence on
               the part of any agent or attorney or an Affiliate appointed
               with due care by it hereunder.

                    The recitals contained herein and in the Certificates
          shall be taken as the statements of the Company and the Agent
          assumes no responsibility for their accuracy. The Agent makes no
          representations as to the validity or sufficiency of either this
          Agreement or of the Securities, or of the Pledge Agreement or the
          Pledge. The Agent shall not be accountable for the use or
          application by the Company of the proceeds in respect of the

          SECTION 7.5.   MAY HOLD SECURITIES.
              

             
                    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 Securities 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.
              

             
          SECTION 7.6.   MONEY HELD IN CUSTODY.
              

             
                    Money held by the Agent in custody hereunder need not
          be segregated from the other funds except to the extent required
          by law or provided herein. The Agent shall be under no obligation
          to invest or pay interest on any money received by it hereunder
          except as otherwise agreed in writing with the Company.
              

             
          SECTION 7.7.   COMPENSATION AND REIMBURSEMENT.
              

             
                    The Company agrees:
              

             
                    (a)  to pay to the Agent from time to time such
               compensation for all services rendered by it hereunder as
               the parties shall agree from time to time (which
               compensation shall not be limited by any provisions of law
               in regards to the compensation of a trustee of an express
               trust);
              

             
                    (b)  except as otherwise expressly provided herein, 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
               (including the reasonable compensation and the expenses and
               disbursements of its agents and counsel), except any such
               expense, disbursement or advance as may be attributable to
               its negligence or bad faith; and
              

             
                    (c)  to indemnify the Agent and any predecessor Agent
               for, and to hold it harmless against, any loss, liability or
               expense incurred without negligence or bad faith on its
               part, arising out of or in connection with the acceptance or
               administration or the performance of its duties hereunder,
               including the costs and expenses of defending itself against
               any claim or liability in connection with the exercise or
               performance of any of its powers or duties hereunder.
              

             
                     Agent  for purposes of this Section 7.7 shall include
          any predecessor Agent; provided, however, that the negligence or
          bad faith of any Agent hereunder shall not affect the rights of
          any other Agent hereunder.
              

             
                    When the Agent incurs expenses or renders services in
          an action or proceeding commenced pursuant to Section 4.3 of the
          Pledge Agreement upon the occurrence of a Termination Event, the
          expenses (including the reasonable charges and expenses of its
          counsel) and the compensation for the services are intended to
          constitute expenses of administration under any applicable
          Federal or State bankruptcy, insolvency or other similar law.
              

             
                    The provisions of this Section 7.7 shall survive the
          termination of this Agreement and the Pledge Agreement.
              

             
          SECTION 7.8.   CORPORATE AGENT REQUIRED; ELIGIBILITY.
              

             
                    There shall at all times be an Agent hereunder which
          shall be (i) not be an Affiliate of the Company and (ii) 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 $50,000,000
          and subject to supervision or examination by Federal or State
          authority.  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 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
               Securities delivered to the Agent and the Company.
              

             
                    (d)  if at any time
              

             
                    (1)  the Agent fails to comply with Section 310(b)
               of the TIA, after written request therefor by the
               Company or by any Holder who has been a bona fide
               Holder of a Security for at least six months, 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, (i) the Company by a Board Resolution may remove
               the Agent, or (ii) any Holder who has been a bona fide
               Holder of a Security 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, the Agent or any Holder who has been a bona
               fide Holder of a Security 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.
              

             
                    (g)  If the Agent has or shall acquire any "conflicting
               interest" within the meaning of Section 310(b) of the Trust
               Indenture Act, the Agent and the Company shall in all
               respects comply with the provisions of Section 310(b) of the
               Trust Indenture Act.
              

             
          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, powers, agencies 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
               and trusts of the retiring Agent and shall 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 and agencies 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 Person into which the Agent may be merged or
          converted or with which it may be consolidated, or any Person
          resulting from any merger, conversion or consolidation to which
          the Agent shall be a party, or any Person succeeding to all or
          substantially all the corporate trust business of the Agent,
          shall be the successor of the Agent hereunder, provided such
          Person 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 may 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 Securities.
              

             
          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 a Security 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 Securities 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 for the payment, of
               the reasonable expenses of such mailing.
              

             
          SECTION 7.13.  NO OBLIGATIONS OF AGENT.
              

             
                    Except to the extent otherwise provided in this
          Agreement, the Agent assumes no obligations and shall not be
          subject to any liability under this Agreement, the Pledge
          Agreement or any Purchase Contract in respect of the obligations
          of the Holder of any Security thereunder. The Company agrees, and
          each Holder of a Certificate, by his 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 Purchase Contracts on behalf
          of the Holders, except to the extent expressly provided in
          Article Five hereof.
              

             
          SECTION 7.14.  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 by applicable tax laws,
               regulations or administrative practice with respect to (i)
               any payments made with respect to the Securities or (ii) the
               issuance, delivery, holding, transfer, redemption or
               exercise of rights under the Securities. 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 written direction
               received from the Company with respect to the application of
               such requirements to particular payments or Holders or in
               other particular circumstances, and may for purposes of this
               Agreement rely on any such direction in accordance with the
               provisions of Section 7.1(a)(2) hereof.
              

             
                    (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.
              

              
                                     ARTICLE VIII

                               SUPPLEMENTAL AGREEMENTS
              

             
          SECTION 8.1.   SUPPLEMENTAL AGREEMENTS WITHOUT CONSENT OF
                         HOLDERS.
              

             
                    Without the consent of any Holders, the Company and the
          Agent, at any time and from time to time, may enter into one or
          more agreements supplemental hereto, in form satisfactory to the
          Company and the Agent, for any of the following purposes:
              

             
                    (a)  to evidence the succession of another Person to
               the Company, and the assumption by any such successor of the
               covenants of the Company herein and in the Certificates; or
              

             
                    (b)  to add to the covenants of the Company for the
               benefit of the Holders, or to surrender any right or power
               herein conferred upon the Company; or
              

             
                    (c)  to evidence and provide for the acceptance of
               appointment hereunder by a successor Agent; or
              

             
                    (d)  to make provision with respect to the rights of
               Holders pursuant to the requirements of Section 5.6(b); or
              

             
                    (e)  to cure any ambiguity, to correct or supplement
               any provisions herein which may be inconsistent with any
               other provisions herein, or to make any other provisions
               with respect to such matters or questions arising under this
               Agreement, provided such action shall not adversely affect
               the interests of the Holders.
              

             
          SECTION 8.2.   SUPPLEMENTAL AGREEMENTS WITH CONSENT OF HOLDERS.
              

             
                    With the consent of the Holders of not less than a
          majority of the outstanding Purchase Contracts voting together as
          one class, by Act of said Holders delivered to the Company and
          the Agent, the Company, when authorized by a Board Resolution,
          and the Agent may enter into an agreement or agreements
          supplemental hereto for the purpose of modifying in any manner
          the terms of the Purchase Contracts, or the provisions of this
          Agreement or the rights of the Holders in respect of the
          Securities; provided, however, that, except as contemplated
          herein, no such supplemental agreement shall, without the consent
          of the Holder of each Outstanding Security affected thereby, 
              

             
                    (a)  change any Payment Date;
              

             
                    (b)  change the amount or the type of Collateral
               required to be Pledged to secure a Holder's Obligations
               under the Purchase Contract, impair the right of the Holder
               of any Purchase Contract to receive distributions on the
               related Collateral (except for the rights of Holders of
               Income PRIDES to substitute the Treasury Securities for the
               Pledged Debt Securities or the rights of holders of Growth
               PRIDES to substitute Debt Securities or the Applicable
               Ownership Interest in the Treasury Portfolio for the Pledged
               Treasury Securities) or otherwise adversely affect the
               Holder's rights in or to such Collateral or adversely alter
               the rights in or to such Collateral;
              

             
                    (c)  reduce any Contract Adjustment Payments or any
               Deferred Contract Adjustment Payment, or change any place
               where, or the coin or currency in which, any Contract
               Adjustment Payment is payable;
              

             
                    (d)  impair the right to institute suit for the
               enforcement of any Purchase Contract;
              

             
                    (e)  reduce the number of shares of Common Stock to be
               purchased pursuant to any Purchase Contract, increase the
               price to purchase shares of Common Stock upon settlement of
               any Purchase Contract, change a Purchase Contract Settlement
               Date or the right to Early Settlement or otherwise adversely
               affect the Holder's rights under any Purchase Contract; or
              

             
                    (f)  reduce the percentage of the outstanding Purchase
               Contracts the consent of whose Holders is required for any
               such supplemental agreement;
              

             
          provided, that if any amendment or proposal referred to above
          would adversely affect only the Income PRIDES or the Growth
          PRIDES, then only the Holders of the affected class of Security
          as of the record date for the Holders entitled to vote thereon
          will be entitled to vote on such amendment or proposal, and such
          amendment or proposal shall not be effective except with the
          consent of Holders of not less than a majority of such class;
          provided further, however, that no such agreement, whether with
          or without the consent of the Holders, shall affect Section 3.16
          hereof.
              

             
                    It shall not be necessary for any Act of Holders under
          this Section to approve the particular form of any proposed
          supplemental agreement, but it shall be sufficient if such Act
          shall approve the substance thereof.
              

             
          SECTION 8.3.   EXECUTION OF SUPPLEMENTAL AGREEMENTS.
              

             
                    In executing, or accepting the additional agencies
          created by, any supplemental agreement permitted by this Article
          or the modifications thereby of the agencies created by this
          Agreement, the Agent shall be entitled to receive and (subject to
          Section 7.1) shall be fully protected in relying upon, an Opinion
          of Counsel stating that the execution of such supplemental
          agreement is authorized or permitted by this Agreement. The Agent
          may, but shall not be obligated to, enter into any such
          supplemental agreement which affects the Agent's own rights,
          duties or immunities under this Agreement or otherwise.
              

             
          SECTION 8.4.   EFFECT OF SUPPLEMENTAL AGREEMENTS.
              

             
                    Upon the execution of any supplemental agreement under
          this Article, this Agreement shall be modified in accordance
          therewith, and such supplemental agreement shall form a part of
          this Agreement for all purposes; and every Holder of Certificates
          theretofore or thereafter authenticated, executed on behalf of
          the Holders and delivered hereunder shall be bound thereby.
              

             
          SECTION 8.5.   REFERENCE TO SUPPLEMENTAL AGREEMENTS.
              

             
                    Certificates authenticated, executed on behalf of the
          Holders and delivered after the execution of any supplemental
          agreement pursuant to this Article may, and shall if required by
          the Agent, bear a notation in form approved by the Agent as to
          any matter provided for in such supplemental agreement. If the
          Company shall so determine, new Certificates so modified as to
          conform, in the opinion of the Agent and the Company, to any such
          supplemental agreement may be prepared and executed by the
          Company and authenticated, executed on behalf of the Holders and
          delivered by the Agent in exchange for Outstanding Certificates.
              

              
                                      ARTICLE IX

                      CONSOLIDATION, MERGER, SALE OR CONVEYANCE
              

             
          SECTION 9.1.   COVENANT NOT TO MERGE, CONSOLIDATE, SELL OR CONVEY
                         PROPERTY EXCEPT UNDER CERTAIN CONDITIONS.
              

             
                    The Company covenants that it will not merge or
          consolidate with any other Person or sell, assign, transfer,
          lease or convey all or substantially all of its properties and
          assets to any Person or group of affiliated Persons in one
          transaction or a series of related transactions, unless (i)

          successor (if other than the Company) shall be a corporation
          organized and existing under the laws of the United States of
          America or a State thereof or the District of Columbia and such
          corporation shall expressly assume all the obligations of the

          Agreement and the Pledge Agreement by one or more supplemental
          agreements in form reasonably satisfactory to the Agent and the
          Collateral Agent, executed and delivered to the Agent and the
          Collateral Agent by such corporation, and (ii) the Company or
          such successor corporation, as the case may be, shall not,
          immediately after such merger or consolidation, or such sale,
          assignment, transfer, lease or conveyance, be in default in its

          SECTION 9.2.   RIGHTS AND DUTIES OF SUCCESSOR CORPORATION.
              

             
                    In case of any such consolidation, merger, sale,
          assignment, transfer, lease or conveyance and upon any such
          assumption by a successor corporation in accordance with Section
          9.1, such successor corporation shall succeed to and be
          substituted for the Company with the same effect as if it had
          been named herein as the Company. Such successor corporation
          thereupon may cause to be signed, and may issue either in its own
          name or in the name of Texas Utilities Company any or all of the
          Certificates evidencing Securities issuable hereunder which
          theretofore shall not have been signed by the Company and
          delivered to the Agent; and, upon the order of such successor
          corporation, instead of the Company, and subject to all the
          terms, conditions and limitations in this Agreement prescribed,
          the Agent shall authenticate and execute on behalf of the Holders
          and deliver any Certificates which previously shall have been
          signed and delivered by the officers of the Company to the Agent
          for authentication and execution, and any Certificate evidencing
          Securities which such successor corporation thereafter shall
          cause to be signed and delivered to the Agent for that purpose.
          All the Certificates so issued shall in all respects have the
          same legal rank and benefit under this Agreement as the
          Certificates theretofore or thereafter issued in accordance with
          the terms of this Agreement as though all of such Certificates
          had been issued at the date of the execution hereof.
              

             
                    In case of any such consolidation, merger, sale,
          assignment, transfer, lease or conveyance such change in
          phraseology and form (but not in substance) may be made in the
          Certificates evidencing Securities thereafter to be issued as may
          be appropriate.

          receive an Opinion of Counsel as conclusive evidence that any
          such consolidation, merger, sale, assignment, transfer, lease or
          conveyance, and any such assumption, complies with the provisions
          of this Article and that all conditions precedent to the
          consummation of any such consolidation, merger, sale, assignment,
          transfer, lease or conveyance have been met.

          Holders from time to time of the Securities that it will duly and
          punctually perform its obligations under the Purchase Contracts
          in accordance with the terms of the Purchase Contracts and this

          SECTION 10.2.  MAINTENANCE OF OFFICE OR AGENCY.
              

             
                    The Company will maintain in the Borough of Manhattan,
          The City of New York an office or agency where Certificates may
          be presented or surrendered for acquisition of shares of Common
          Stock upon settlement of the Purchase Contracts on the Purchase
          Contract Settlement Date or Early Settlement and for transfer of
          Collateral upon occurrence of a Termination Event, where
          Certificates may be surrendered for registration of transfer or
          exchange, for a Collateral Substitution or establishment of an
          Income PRIDES and where notices and demands to or upon the
          Company in respect of the Securities and this Agreement may be
          served. The Company will give prompt written notice to the Agent
          of the location, and any change in the location, of such office
          or agency. If at any time the Company shall fail to maintain any
          such required office or agency or shall fail to furnish the Agent
          with the address thereof, such presentations, surrenders, notices
          and demands may be made or served at the Corporate Trust Office,

                    The Company may also from time to time designate one or
          more other offices or agencies where Certificates may be
          presented or surrendered for any or all such purposes and may
          from time to time rescind such designations; provided, however,
          that no such designation or rescission shall in any manner
          relieve the Company of its obligation to maintain an office or
          agency in the Borough of Manhattan, The City of New York for such
          purposes. The Company will give prompt written notice to the
          Agent of any such designation or rescission and of any change in
          the location of any such other office or agency. The Company
          hereby designates as the place of payment for the Securities the
          Corporate Trust Office and appoints the Agent at its Corporate
          Trust Office as paying agent in such city.

          clauses (A)(i) and (B)(i) of the  definition of such term) in the
          Treasury Portfolio, as the  case may be, that have  been released

          on a  Business Day,  then such payment shall  be made no  later

          respective obligations of  the Holders  of the  Income PRIDES  of
          which such Pledged Debt Securities or the Treasury  Portfolio, as
          the  case may be, are a part under the Purchase Contracts forming
          a part  of such  Income PRIDES. Payment  of interest on  any Debt
          Security or distributions on the appropriate Applicable Ownership
          Interest (as  specified  in clauses  (A)(ii) and  (B)(ii) of  the

          may be, forming part  of an Income PRIDES evidenced  hereby which
          are  payable   quarterly  in  arrears  on   February 16,  May 16,
          August 16 and  November 16 each year, commencing  August 16, 1998
          (a  "Payment Date"),  shall,  subject to  receipt thereof  by the
          Agent from  the Collateral Agent, be paid  to the Person in whose
          name  this Income  PRIDES  Certificate (or  a Predecessor  Income
          PRIDES Certificate) is registered at the close of business on the
          Record Date for such Payment Date.
              

               Each Purchase Contract evidenced hereby obligates the Holder
          of this Income PRIDES Certificate to purchase, and the Company to
          sell, (i)  not later than  August 16, 2001  (the "First  Purchase
          Contract Settlement Date"), at a price  equal to $25 in cash (the
          "Purchase  Price"), a  number of  newly issued  shares  of Common
          Stock,  no par value, of  the Company ("Common  Stock"), equal to
          the applicable Settlement Rate  (as defined below) and (ii)   not
          later  than  August 16,  2002  (the   "Second  Purchase  Contract
          Settlement Date" and with  the First Purchase Contract Settlement
          Date, each, a "Purchase Contract Settlement Date"), at a price of
          $25 in  cash, a number  of newly issued  shares of  Common Stock,
          equal  to the applicable Settlement  Rate, unless on  or prior to
          the applicable Purchase Contract Settlement Date there shall have
          occurred a Termination  Event or an Early Settlement with respect
          to the Income  PRIDES of which such Purchase Contract  is a part,
          all as provided in the Purchase Contract Agreement and more fully
          described below. 
              

               The "Settlement  Rate" with  respect to a  Purchase Contract
          Settlement  Date is equal to  (a) if the  Applicable Market Value
          (as  defined  below) determined  with  respect  to such  Purchase
          Contract  Settlement Date is equal to or greater than $49.19 (the
          "Threshold Appreciation Price"), .5082 shares of Common Stock per
          Purchase  Contract, (b) if  such Applicable Market  Value is less
          than  the  Threshold  Appreciation  Price  but  is  greater  than
          $41.6875,  the number  of  shares of  Common  Stock per  Purchase
          Contract equal to $25 divided by such Applicable Market Value and
          (c) if  the Applicable  Market Value  is  less than  or equal  to
          $41.6875, .5997 shares of Common Stock per Purchase  Contract, in
          each case  subject  to adjustment  as  provided in  the  Purchase
          Contract Agreement. No  fractional shares of Common Stock will be
          issued upon settlement of Purchase  Contracts, as provided in the
          Purchase Contract Agreement.
              

               The Company shall pay,  on each Payment Date, in  respect of
          each Purchase Contract evidenced  hereby an amount (the "Contract
          Adjustment  Payments") equal to (A)  for the period  prior to the
          First  Purchase Contract Settlement Date, 2.815% per annum of the
          Stated Amount, and  (B) for the period  from and after  the First
          Purchase  Contract  Settlement  Date,  2.75%  per  annum  of  the
          Remaining  Stated Amount, computed, in each case, 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 Purchase Contract
          Agreement  and  more  fully   described  below.    Such  Contract
          Adjustment  Payments shall be payable to the Person in whose name
          this Income  PRIDES Certificate  (or a Predecessor  Income PRIDES
          Certificate) is registered at the close of business on the Record
          Date for such Payment Date.
              

               Payment of interest on  the Debt Securities or distributions
          on the appropriate Applicable Ownership Interest (as specified in
          clauses  (A)(ii) and (B)(ii) of  the definition of  such term) in
          the  Treasury  Portfolio,  as  the  case  may  be,  and  Contract
          Adjustment Payments will be payable at the office of the Agent in
          The City of New York or,  at the option of the Company,  by check
          mailed  to the  address of  the Person  entitled thereto  as such
          address appears on the Income PRIDES Register.
              

               Unless the context otherwise requires, each provision of this
          security shall be part of the Purchase Comtracts evidenced hereby.
          This Security and each Purchase Contract evidenced hereby is
          governed  by a Purchase Contract  Agreement, dated as  of July 1,
          1998 (as may  be supplemented  from time to  time, the  "Purchase
          Contract Agreement"),  between the Company  and The  Bank of  New
          York,  as  Purchase  Contract  Agent and  trustee  including  its
          successor thereunder,  (herein  called  the  "Agent"),  to  which
          Purchase Contract  Agreement and supplemental  agreements thereto
          reference is  hereby  made for  a description  of the  respective
          rights, limitations of rights, obligations, duties and immunities
          thereunder  of the Agent, the Company, and the Holders and of the
          terms upon which the  Income PRIDES Certificates are, and  are to
          be, executed and delivered.
              

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

               The  "Applicable Market  Value" with  respect to  a Purchase
          Contract Settlement Date  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 such
          Purchase  Contract Settlement  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, 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  at the  close of  business and  (B) has
          traded  at least  once  on the  national  or regional  securities
          exchange  or  association that  is  the  primary market  for  the
          trading of the Common Stock.
              

               In  accordance  with  the  terms of  the  Purchase  Contract
          Agreement, the Holder of the Income PRIDES evidenced hereby shall
          pay,  on each  Purchase Contract  Settlement Date  the applicable
          Purchase Price for the shares of Common Stock purchased  pursuant
          to each  Purchase Contract evidenced  hereby by effecting  a Cash
          Settlement or, an Early Settlement. A Holder of Income PRIDES who
          does  not  make  such payment  in  accordance  with the  Purchase
          Contract  Agreement  or who  does not  notify  the Agent  of such
          Holder's intention, on or prior  to 5:00 p.m. New York  City time
          on  the  fifth  Business  Day immediately  preceding  a  Purchase
          Contract Settlement Date, to make an effective Cash Settlement or
          an  Early Settlement,  shall  have defaulted  in its  obligations
          under the  applicable portion  of the related  Purchase Contract,
          and the Collateral Agent  shall exercise its rights as  a secured
          creditor  for the benefit of the Company thereunder and under the
          Pledge Agreement and shall apply the  Proceeds of the sale of the
          applicable related  Pledged Debt  Securities (which shall  be the
          Series D  Notes in  connection with the  First Purchase  Contract
          Settlement  Date and Series E Notes in connection with the Second
          Purchase Contract  Settlement Date) held by  the Collateral Agent
          to satisfy  the Holder's obligation under  such Purchase Contract
          to purchase Common Stock at the Purchase Price. 
              

               The  Company shall not be  obligated to issue  any shares of
          Common Stock in  respect of any portion of a Purchase Contract on
          a Purchase  Contract Settlement Date or  deliver any certificates
          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 and  the Purchase
          Contract Agreement, the  Agent will be  entitled to exercise  the
          voting and any other consensual rights pertaining to  the Pledged
          Debt Securities. Upon receipt  of notice of any meeting  at which
          holders  of  Debt Securities  are entitled  to  vote or  upon the
          solicitation of consents,  waivers or proxies of  holders of Debt
          Securities, the  Agent shall, as soon  as practicable thereafter,
          mail  to the Income PRIDES  holders a notice  (a) containing such
          information as  is contained in  the notice or  solicitation, (b)
          stating that each Income  PRIDES Holder on the record date set by
          the Agent therefor shall be entitled  to instruct the Agent as to
          the  exercise  of  the  voting  rights  pertaining  to  the  Debt
          Securities constituting a part of such Holder's Income PRIDES and
          (c) stating the manner  in which such instructions may  be given.
          Upon the written  request of  the Income PRIDES  Holders on  such
          record date, the Agent shall  endeavor insofar as practicable  to
          vote  or cause to be  voted, in accordance  with the instructions
          set forth in such requests, the maximum number of Debt Securities
          as to which  any particular voting instructions  are received. In
          the absence of specific instructions from the Holder of an Income
          PRIDES,  the Agent shall abstain from  voting any Debt Securities
          evidenced by such Income PRIDES. 
              

               Upon the occurrence of  a Tax Event Redemption prior  to the
          Second Purchase Contract  Settlement Date,  the Redemption  Price
          payable  on the  Tax Event  Redemption Date  with respect  to the
          Pledged  Debt Securities  shall  be delivered  to the  Collateral
          Agent in exchange for  the Pledged Debt Securities.   Pursuant to
          the terms of the  Pledge Agreement, the Collateral Agent  for the
          benefit  of the  Company  will  apply  an  amount  equal  to  the
          applicable Redemption Amount of such Redemption Price to purchase
          the  Treasury Portfolio  and  will promptly  remit the  remaining
          portion of such Redemption Price to the Agent  for payment to the
          Holders of such Income PRIDES.  Following the occurrence of a Tax
          Event Redemption prior to the Second Purchase Contract Settlement
          Date, the Holders of Income PRIDES and the Collateral Agent shall
          have such security interests  rights and obligations with respect
          to the Treasury Portfolio as the Holder  of Income PRIDES and the
          Collateral  Agent had in respect  of the Debt  Securities, as the
          case  may be, subject  to the Pledge  thereof as provided  in the
          Pledge Agreement and any reference  herein to the Debt Securities
          shall be deemed to be a reference to such Treasury Portfolio.
              

               The Income PRIDES  are issuable only in  registered form and
          only  in denominations of a single Income PRIDES and any integral
          multiple thereof.  The transfer of any  Income PRIDES Certificate
          will  be  registered  and   Income  PRIDES  Certificates  may  be
          exchanged as provided  in the Purchase  Contract Agreement.   The
          Income PRIDES Registrar may require a Holder, among other things,
          to  furnish  appropriate  endorsements  and   transfer  documents
          permitted by the Purchase Contract Agreement.  No service  charge
          shall  be  required  for any  such  registration  of  transfer or
          exchange, but the Company and the  Agent may require payment of a
          sum  sufficient  to cover  any tax  or other  governmental charge
          payable in connection therewith.
              

               A Holder of an Income PRIDES may, at any time on or prior to
          the fifth Business Day  immediately preceding the Second Purchase
          Contract Settlement Date, create or recreate a Growth PRIDES  and
          separate  the  Debt  Securities  or  the  appropriate  Applicable
          Ownership Interest in the Treasury Portfolio, as applicable, from
          the related Purchase Contract in respect of such Income PRIDES by
          substituting  3-Year  Treasury  Securities  and  4-Year  Treasury
          Securities for all, but not  less than all, of the Series  D Note
          and the  Series E  Note, respectively, or  appropriate Applicable
          Ownership Interest in the Treasury Portfolio, as the case may be,
          that form  a part of  such Income  PRIDES in accordance  with the
          Purchase  Contract  Agreement;   provided,  however,  that   such
          Collateral Substitutions may not  be made during the period  from
          the fifth  Business Day immediately preceding  the First Purchase
          Contract  Settlement  Date  through the  First  Purchase Contract
          Settlement Date,  except  that  if  a Tax  Event  Redemption  has
          occurred and the Treasury Portfolio has become a component of the
          Income PRIDES,  Holders  of  such Income  PRIDES  may  make  such
          Collateral  Substitutions at any time  on or prior  to the second
          Business Day immediately  preceding the Second  Purchase Contract
          Settlement  Date (but  not  during  the  period from  the  second
          Business Day  immediately preceding  the First Purchase  Contract
          Settlement  Date through the  First Purchase  Contract Settlement
          Date).  Holders  may make  Collateral Substitutions  (i) only  in
          integral multiples  of 40 Income  PRIDES if  Debt Securities  are
          being  substituted  by  Treasury  Securities,  or  (ii)  only  in
          integral multiples of 1,600,000  Income PRIDES if the appropriate
          Applicable  Ownership  Interests in  the  Treasury  Portfolio are
          being  substituted by Treasury  Securities.  To  create 40 Growth
          PRIDES (if a Tax Event Redemption has not occurred), or 1,600,000
          Growth  PRIDES (if  a  Tax Event  Redemption  has occurred),  the
          Income PRIDES Holder shall
              

                    (a) if  a Tax  Event Redemption has  not occurred,  (i)
               prior to the fifth Business Day preceding the First Purchase
               Contract Settlement Date, deposit with the  Collateral Agent
               a  3-Year Treasury  Security  having a  principal amount  at
               maturity of  $1,000 and a 4-Year Treasury  Security having a
               principal amount  at maturity of  $1,000, or (ii)  after the
               First  Purchase Contract  Settlement Date  and prior  to the
               fifth Business Day  preceding the  Second Purchase  Contract
               Settlement Date, deposit with  the Collateral Agent a 4-Year
               Treasury Security  having a principal amount  at maturity of
               $1,000; or
              

                    (b) if  a Tax Event Redemption has  occurred, (i) prior
               to the  second Business Day immediately  preceding the First
               Purchase   Contract  Settlement   Date,  deposit   with  the
               Collateral   Agent  3-Year  Treasury  Securities  having  an
               aggregate principal amount at maturity of $40,000,000 and 4-
               Year  Treasury  Securities  having  an  aggregate  principal
               amount  at maturity of $40,000,000,  or (ii) after the First
               Purchase Contract  Settlement Date  and prior to  the second
               Business  Day  immediately  preceding  the  Second  Purchase
               Contract  Settlement Date, 4-Year Treasury Securities having
               an aggregate  principal amount at  maturity of  $40,000,000;
               and
              

                    (c) in either case, (i) deliver cash to the Agent in an
               amount  equal  to  the  excess of  the  Contract  Adjustment
               Payments that would have accrued  on the Growth PRIDES being
               created  by the Holder  since the last  Payment Date through
               the  date  of  Collateral Substitution,  over  the  Contract
               Adjustment  Payments that  have accrued  over the  same time
               period on the Income  PRIDES being surrendered in connection
               with such  Collateral Substitution,  which amount the  Agent
               shall  promptly remit to the Company,  and (ii) transfer the
               40  Income PRIDES, or, in  the event a  Tax Event Redemption
               has  occurred,   1,600,000  Income  PRIDES,   to  the  Agent
               accompanied by a  notice to the Agent,  substantially in the
               form  of Exhibit B to the Pledge Agreement, stating that the
               Holder  has transferred  the relevant  types and  amounts of
               Treasury Securities to the  Collateral Agent and  requesting
               that the Agent instruct the  Collateral Agent to release the
               applicable  Debt  Securities or  the  appropriate Applicable
               Ownership Interest  in the  Treasury Portfolio, as  the case
               may be,  underlying such Income PRIDES,  whereupon the Agent
               shall  promptly  give such  instructions  to the  Collateral
               Agent,  substantially in the form of Exhibit A to the Pledge
               Agreement. 
              

              Upon receipt  of the Treasury Securities  described in clause
          (a) or (b)  above and  the instructions described  in clause  (c)
          above,  in accordance with the terms of the Pledge Agreement, the
          Collateral  Agent will release from  the Pledge to  the Agent, on
          behalf  of  the  Holder,   Debt  Securities  or  the  appropriate
          Applicable Ownership  Interest in the Treasury  Portfolio, as the
          case may be, that had been components of such Income PRIDES, free
          and clear of  the Company's security  interest therein, and  upon
          receipt thereof the Agent shall promptly:
              

                    (i) cancel  the related Income  PRIDES surrendered
               and transferred;
              

                    (ii)  transfer   the   Debt  Securities   or   the
               appropriate  Applicable  Ownership   Interest  in   the
               Treasury Portfolio, as the  case may be, that had  been
               components of such Income PRIDES to the Holder; and
              

                    (iii)  authenticate,  execute  on  behalf  of such
               Holder and deliver a Growth PRIDES Certificate executed
               by the Company in accordance with the Purchase Contract
               Agreement  evidencing  the  same  number   of  Purchase
               Contracts  as were  evidenced  by  the canceled  Income
               PRIDES.
              

               Holders who  elect to separate  the Debt  Securities or  the
          appropriate   Applicable  Ownership  Interest   in  the  Treasury
          Portfolio,  as  the  case  may  be,  from  the  related  Purchase
          Contracts  and to  substitute Treasury  Securities for  such Debt
          Securities or  the appropriate Applicable  Ownership Interest  in
          the  Treasury Portfolio, as the case may be, 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 beresponsible for any such feesor expenses.
              

               A  Holder of  Growth PRIDES  may create  or  recreate Income
          PRIDES by  depositing with  the Collateral Agent  Debt Securities
          having an aggregate principal amount, in the case of the Series D
          Notes  and the Series E  Notes, equal to  the aggregate principal
          amount at  maturity, of the 3-Year Treasury Securities and 4-Year
          Treasury Securities, respectively, comprising part of  the Growth
          PRIDES, or by so  depositing the appropriate Applicable Ownership
          Interest  in the Treasury Portfolio, in  exchange for the release
          of such Pledged Treasury Securities, in accordance with the terms
          of the Purchase Contract Agreement and the Pledge Agreement.
              

               The Company  shall have the right, at  any time prior to the
          Second Purchase Contract Settlement Date, to defer the payment of
          any or all of the  Contract Adjustment Payments otherwise payable
          on any Payment Date to a date no later than the Purchase Contract
          Settlement Date next succeeding the date such deferral commences,
          but only  if the Company  shall give  the Holders  and the  Agent
          written notice of  its election to defer such payment (specifying
          the amount to be  deferred) as provided in the  Purchase Contract
          Agreement.   In connection with any  Contract Adjustment Payments
          so  deferred,  additional  Contract  Adjustment  Payments  on the
          amounts  so deferred will  accrue at the rate  of 9.75% per annum
          (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,  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   Purchase  Contract  Agreement.  No   Contract
          Adjustment Payments may  be deferred to a date that  is after the
          Purchase Contract  Settlement Date next succeeding  the date such
          deferral commences.
              

               In the event that the Company elects to defer the payment of
          Contract Adjustment Payments on  the Purchase Contracts until the
          next succeeding Purchase Contract  Settlement Date, the Holder of
          this  Income PRIDES  Certificate  will receive  on such  Purchase
          Contract Settlement Date, in  lieu of a cash payment, a number of
          shares  of  Common Stock  equal to  (x)  the aggregate  amount of
          Deferred Contract  Adjustment Payments  payable to the  Holder of
          this  Income PRIDES  Certificate  divided by  (y) the  Applicable
          Market Value related to such Purchase Contract Settlement 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  capital  stock or  make guarantee
          payments with respect  to the foregoing (other than (i) purchases
          or acquisitions  of capital  stock of  the Company  in connection
          with the satisfaction by the Company of its obligations under any
          employee  or agent  benefit  plans  or  the satisfaction  by  the
          Company of its obligations  pursuant to any contract or  security
          outstanding  on the date of  such event requiring  the Company to
          purchase   its   capital   stock,  (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  the
          Company's capital  stock pursuant  to the conversion  or exchange
          provisions of  the Company's capital stock or  the security being
          converted  or  exchanged,  (iv)  dividends  or  distributions  in
          capital stock of the Company (or rights to acquire capital stock)
          or repurchases or  redemptions of capital  stock solely from  the
          issuance  or exchange  of  capital stock  or  (v) redemptions  or
          repurchases of any rights  outstanding under a shareholder rights
          plan.
              

               The Purchase Contracts and all obligations and rights of the
          Company   and   the   Holders  thereunder,   including,   without
          limitation,  the  rights  of  the  Holders  to  receive  and  the
          obligation of the Company to pay any Contract Adjustment Payments
          or any Deferred Contract Adjustment Payments, and the  rights and
          obligations  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  Second Purchase Contract  Settlement Date, a
          Termination Event  shall have occurred. Upon the  occurrence of a
          Termination  Event, the  Company shall  promptly but in  no event
          later than  two Business Days  thereafter give written  notice to
          the  Agent, the  Collateral Agent  and to  the Holders,  at their
          addresses  as they appear in the Income PRIDES Register. Upon and
          after the occurrence of a Termination Event, the Collateral Agent
          shall release  the Debt Securities or  the appropriate Applicable
          Ownership Interest in the Treasury Portfolio, as the case may be,
          forming a part  of the  Income PRIDES evidenced  hereby from  the
          Pledge in accordance with the provisions of the Pledge Agreement.
              

               Subject to  and upon compliance  with the provisions  of the
          Purchase Contract Agreement, a Holder of Income PRIDES may settle
          the related Purchase Contracts  in their entirety on or  prior to
          the  fifth Business  Day  immediately  preceding either  Purchase
          Contract  Settlement Date, but  only in integral  multiples of 40
          Income PRIDES;  provided, however, that such  settlements may not
          be made during the  fifth Business Day immediately preceding  the
          First  Purchase  Contract  Settlement  Date   through  the  First
          Purchase Contract Settlement Date; and provided, further, that if
          a Tax  Event Redemption has  occurred and the  Treasury Portfolio
          has become a component  of the Income PRIDES, Holders  may settle
          early only in  integral multiples of  1,600,000 Income PRIDES  at
          any  time  on or  prior to  the  second Business  Day immediately
          preceding such Purchase Contract  Settlement Date (but not during
          the  period two  Business  Days immediately  preceding the  First
          Purchase  Contract  Settlement  Date through  the  First Purchase
          Contract  Settlement Date).  In order  to exercise  the right  to
          effect  any  such  early  settlement  ("Early  Settlement")  with
          respect  to  any  Purchase  Contracts evidenced  by  this  Income
          PRIDES,  the  Holder  of  this Income  PRIDES  Certificate  shall
          deliver this  Income  PRIDES  Certificate to  the  Agent  at  the
          Corporate Trust Office duly endorsed  for transfer to the Company
          or in blank with the  form of Election to Settle Early  set forth
          below  duly completed and accompanied  by payment in  the form of
          immediately available funds payable  to the order of the  Company
          in an amount  (the "Early Settlement Amount") equal to the sum of
          (i)(A) $50 times the  number of Purchase Contracts  being settled
          if  settled on  or prior  to the  fifth Business  Day immediately
          preceding  the First Purchase Contract Settlement Date or (B) $25
          times  the number of Purchase  Contracts being settled if settled
          after the First Purchase Contract Settlement Date plus, in either
          case, (ii) if such  delivery is made with respect to any 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 payable on such Payment  Date with respect to
          such  Purchase  Contracts.  Upon  Early  Settlement  of  Purchase
          Contracts by a Holder of the related Securities, the Pledged Debt
          Securities or  the appropriate  Applicable Ownership  Interest in
          the  Treasury  Portfolio  underlying  such  Securities  shall  be
          released  from the Pledge as provided in the Pledge Agreement and
          the  Holder shall  be entitled to  receive a number  of shares of
          Common Stock on account of each Purchase Contract forming part of
          an Income PRIDES as  to which Early Settlement is  effected equal
          to the  applicable Early Settlement Rate;  provided however, that
          upon  the Early  Settlement  of the  Purchase Contracts,  (i) the
          Holder thereof  will forfeit  the right to  receive any  Deferred
          Contract Adjustment Payments, if any, on such Purchase Contracts,
          (ii) the Holder's right to receive additional Contract Adjustment
          Payments in  respect of  such Purchase Contracts  will terminate,
          and  (iii) no  adjustment will be  made to  or for  the Holder on
          account of  Deferred Contract Adjustment Payments,  or any amount
          accrued  in respect  of Contract  Adjustment Payments.  The Early
          Settlement Rate shall initially  be equal to 1.0164  newly issued
          shares of  Common  Stock  per  Income PRIDES  (the  "First  Early
          Settlement Rate") if settled prior to the First Purchase Contract
          Settlement Date, and equal to .5082 (the "Second Early Settlement
          Rate") newly issued shares  of Common Stock per Income  PRIDES if
          settled after the First Purchase  Contract Settlement Date.   The
          First Early Settlement Rate and the Second Early Settlement  Rate
          shall each be adjusted in the same manner and at the same time as
          the  Settlement Rate  is adjusted,  as provided  in the  Purchase
          Contract Agreement.
              

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

               The  Holder  of  this  Income  PRIDES  Certificate,  by  its
          acceptance hereof, authorizes the Agent to enter into and perform
          the related Purchase Contracts forming part  of the Income PRIDES
          evidenced hereby on its behalf as its attorney-in-fact, expressly
          withholds any consent to the assumption (i.e., affirmance) of the
          Purchase Contracts by  the Company  or its trustee  in the  event
          that  the Company  becomes  the  subject  of  a  case  under  the
          Bankruptcy Code, agrees to  be bound by the terms  and provisions
          thereof, covenants  and agrees  to perform its  obligations under
          such  Purchase  Contracts,  consents  to the  provisions  of  the
          Purchase Contract  Agreement, authorizes the Agent  to enter into
          and  perform  the   Pledge  Agreement  on   its  behalf  as   its
          attorney-in-fact,  and  consents  to   the  Pledge  of  the  Debt
          Securities  or the appropriate  Applicable Ownership  Interest in
          the  Treasury  Portfolio, as  the  case may  be,  underlying this
          Income PRIDES  Certificate pursuant to the  Pledge Agreement. The
          Holder further covenants and  agrees, that, to the extent  and in
          the manner provided  in the Purchase  Contract Agreement and  the
          Pledge Agreement, but subject  to the terms thereof, payments  in
          respect  of  the  Pledged  Debt Securities,  or  the  appropriate
          Applicable Ownership Interest in  the Treasury Portfolio, on each
          Purchase Contract Settlement Date shall be paid by the Collateral
          Agent to the Company in satisfaction of such Holder's obligations
          under such  Purchase Contract  and such  Holder shall acquire  no
          right, title or interest in such payments.
              

               The  Holder  of  this  Income  PRIDES  Certificate,  by  its
          acceptance hereof,  covenants and agrees  to treat itself  as the
          owner,  for United  States federal,  state and  local income  and
          franchise tax purposes, of the Debt Securities or the appropriate
          Applicable Ownership Interest  in the Treasury Portfolio  forming
          part of  the Income PRIDES evidenced hereby.   The Holder of this
          Income PRIDES  Certificate,  by its  acceptance  hereof,  further
          covenants and agrees to treat the Debt Securities forming part of
          the Income PRIDES evidenced hereby as indebtedness of the Company
          for United  States federal, state and local  income and franchise
          tax purposes.
              

               Subject  to  certain  exceptions,  the  provisions   of  the
          Purchase  Contract Agreement may  be amended with  the consent of
          the  Holders of  a  majority  of  the  Purchase  Contracts.    In
          addition, certain  amendments to the Purchase  Contract Agreement
          may be made without any consent of the Holders as provided in the
          Purchase Contract Agreement.
              

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

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

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

               A copy of the  Purchase Contract Agreement is available  for
          inspection at  the offices of  the Agent during  regular business
          hours of the Agent.
              

               Unless  the certificate  of authentication  hereon has  been
          executed by  the Agent  by manual  signature, this  Income PRIDES
          Certificate shall not be entitled to any benefit under the Pledge
          Agreement  or  the Purchase  Contract  Agreement or  be  valid or
          obligatory for any purpose.
              

               IN WITNESS  WHEREOF, the Company has  caused this instrument
          to be duly executed.

          then such payment  shall be made  no later than  10:30 a.m.,  New

          Company ("Common Stock") equal  to the applicable Settlement Rate
          (as defined below) and (ii), not later than August 16, 2002  (the
          "Second  Purchase Contract  Settlement Date"  and with  the First
          Purchase  Contract  Settlement Date,  each  a  "Purchase Contract
          Settlement Date")  at a price of  $25 in cash, a  number of newly
          issued shares of Common stock equal  to the applicable Settlement
          Rate,  unless, in  either  case on  or  prior to  the  applicable
          Purchase  Contract Settlement  Date there  shall have  occurred a
          Termination  Event or  an Early  Settlement with  respect  to the
          Growth PRIDES of  which such Purchase Contract is a  part, all as
          provided  in  the  Purchase  Contract Agreement  and  more  fully
          described below. 
              

               The "Settlement  Rate" with  respect to a  Purchase Contract
          Settlement  Date is equal to  (a) if the  Applicable Market Value
          (as  defined  below) determined  with  respect  to such  Purchase
          Contract  Settlement Date is equal to or greater than $49.19 (the
          "Threshold Appreciation Price"), .5082 shares of Common Stock per
          Purchase Contract, (b)  if such Applicable  Market Value is  less
          than  the  Threshold  Appreciation  Price  but  is  greater  than
          $41.6875,  the number  of  shares of  Common  Stock per  Purchase
          Contract equal to $25 divided by such Applicable Market Value and
          (c)  if the  Applicable Market  Value is  less than  or  equal to
          $41.6875,  .5997 shares of Common Stock per Purchase Contract, in
          each  case  subject to  adjustment  as provided  in  the Purchase
          Contract Agreement. No fractional shares  of Common Stock will be
          issued upon settlement of Purchase Contracts, as  provided in the
          Purchase Contract Agreement.
              

               The Company shall  pay on  each Payment Date  in respect  of
          each Purchase Contract evidenced  hereby an amount (the "Contract
          Adjustment  Payments") equal to (A)  for the period  prior to the
          First Purchase Contract  Settlement Date, 3.315% per annum of the
          Stated Amount,  or, and  (B) for  the period  from and  after the
          First  Purchase Contract Date,  3.25% per annum  of the Remaining
          Stated Amount, computed, in each case, 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 Purchase Contract  Agreement and
          more  fully described  below. Such  Contract Adjustment  Payments
          shall be payable to  the Person in whose name this  Growth PRIDES
          Certificate  (or  a  Predecessor  Growth PRIDES  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 The City  of New York or,  at the option  of the
          Company,  by check mailed to  the address of  the Person entitled
          thereto as such address appears on the Growth PRIDES Register.
              

               Unless the context otherwise requires, each provision of this
          security shall be part of the Purchase Contracts evidenced hereby.
          This Security and each Purchase Contract evidenced hereby is
          governed  by a Purchase Contract  Agreement, dated as  of July 1,
          1998 (as may  be supplemented  from time to  time, the  "Purchase
          Contract Agreement")  between the  Company and  The  Bank of  New
          York,  as  Purchase Contract  Agent  and  trustee (including  its
          successors thereunder,  herein called the "Agent"),  to which the
          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  Growth PRIDES Certificates are, and  are to
          be, executed and delivered.
              

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

               The  "Applicable Market  Value" with  respect to  a Purchase
          Contract Settlement Date  means the average of the  Closing Price
          per  share  of Common  Stock on  each  of the  twenty consecutive
          Trading  Days  ending  on   the  third  Trading  Day  immediately
          preceding  such Purchase  Contract Settlement 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, 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 exchange  or association or  over-the-counter
          market that is the primary  market for the trading of the  Common
          Stock.
              

               In  accordance  with  the  terms of  the  Purchase  Contract
          Agreement, the Holder of the Growth PRIDES evidenced hereby shall
          pay, on  each Purchase  Contract Settlement Date,  the applicable
          Purchase Price for the shares of Common  Stock purchased pursuant
          to each Purchase  Contract evidenced hereby  by effecting a  Cash
          Settlement or an Early Settlement.  A Holder of Growth PRIDES who
          does not make such payment in accordance with the Purchase Contract
          Agreement or does not notify the Agent  of such Holder's intention,
          on or prior  to 5:00 p.m. New York City  time  on  the  fifth
          Business  Day immediately  preceding  a  Purchase Contract
          Settlement Date, to make an effective Cash Settlement or an
          Early Settlement,  shall  have defaulted  in its  obligations
          under the  applicable portion  of the related  Purchase Contract,
          and the Collateral Agent  shall exercise its rights as  a secured
          creditor  for the  benefit  of  the  Company under  the  Purchase
          Contract Agreement and the  Pledge Agreement and shall apply  the
          principal  amount at  maturity  of the  related Pledged  Treasury
          Securities (which shall  be the 3-Year  Treasury Security in  the
          case of the First  Purchase Contract Settlement Date, and  the 4-
          Year Treasury  Security  in  the  case  of  the  Second  Purchase
          Contract Settlement  Date) held  by the  Collateral Agent to  the
          Purchase  Price of  the Common  Stock on  such Purchase  Contract
          Settlement Date.
              

               The  Company shall not be  obligated to issue  any shares of
          Common Stock  in respect of any portion of a Purchase Contract on
          a Purchase  Contract Settlement Date or  deliver any certificates
          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 Growth PRIDES are  issuable only in registered form  and
          only  in denominations of a single Growth PRIDES and any integral
          multiple  thereof.  The transfer  of  any Growth  PRIDES  will be
          registered  and Growth PRIDES may be exchanged as provided in the
          Purchase  Contract Agreement.  The  Growth  PRIDES Registrar  may
          require  a Holder,  among  other things,  to furnish  appropriate
          endorsements  and  transfer documents  permitted by  the Purchase
          Contract Agreement. No service charge  shall be required for  any
          such registration of  transfer or exchange,  but the Company  and
          the  Agent may require payment  of a sum  sufficient to cover any
          tax or other governmental charge payable in connection therewith.
              

               A Holder of a Growth PRIDES may, at  any time on or prior to
          the fifth Business Day  immediately preceding the Second Purchase
          Contract Settlement Date, create or  recreate an Income PRIDES by
          (a) depositing with the Collateral  Agent Debt Securities or  the
          appropriate  Applicable  Ownership   Interest  in  the   Treasury
          Portfolio, as  the case  may be,  having  an aggregate  principal
          amount equal  to the aggregate  principal amount at  maturity of,
          and  in substitution  for  all, but  not  less than  all,  of the
          Treasury  Securities  comprising part  of  the  Growth PRIDES  in
          accordance  with  the  Purchase  Contract   Agreement;  provided,
          however,  that  such Collateral  Substitutions  may  not be  made
          during  the  period  from  the  fifth  Business  Day  immediately
          preceding the First Purchase Contract Settlement Date through the
          First  Purchase Contract  Settlement Date, except  that if  a Tax
          Event  Redemption has  occurred  and the  Treasury Portfolio  has
          become a component of the Income PRIDES, Holders of Growth PRIDES
          may make Collateral Substitutions, at any time on or prior to the
          second  Business Day  immediately preceding  the Second  Purchase
          Contract  Settlement Date  (but not  during  the period  from the
          second  Business Day  immediately  preceding  the First  Purchase
          Contract  Settlement  Date through  the  First Purchase  Contract
          Settlement  Date).    Holders  of  Growth  PRIDES may  make  such
          Collateral Substitutions and establish  Income PRIDES only (i) in
          integral multiples  of 40 Growth PRIDES for 40 Income PRIDES if a
          Tax  Event  Redemption has  not  occurred,  or (ii)  in  integral
          multiples of 1,600,000 Growth  PRIDES for 1,600,000 Income PRIDES
          if  a Tax Event  Redemption has  occurred.   To create  40 Income
          PRIDES (if a Tax Event Redemption has not occurred), or 1,600,000
          Income  PRIDES  (if a  Tax  Event Redemption  has  occurred), the
          Growth PRIDES Holder shall
              

                    (a)  if a  Tax Event  Redemption has not  occurred, (i)
               prior to the fifth Business Day preceding the First Purchase
               Contract Settlement  Date, deposit with the Collateral Agent
               $1,000  in aggregate principal amount of  Series D Notes and
               $1,000 in aggregate  principal amount of Series E  Notes, or
               (ii)  after the  First  Purchase Contract  Settlement  Date,
               deposit  with  the  Collateral  Agent  $1,000  in  aggregate
               principal amount of Series E Notes, or
              

                    (b)  if a  Tax Event  Redemption has  occurred, deposit
               with the Collateral Agent  the Applicable Ownership Interest
               in  the  Treasury Portfolio  for  each  Income PRIDES  being
               created  by the  Holder  and having  an aggregate  principal
               amount  of  $80,000,000, or  if,  after  the First  Purchase
               Contract Settlement Date $40,000,000, and
              

                    (c) in either case,  transfer and surrender the related
               40 Growth PRIDES, or in the event a Tax Event Redemption has
               occurred, 1,600,000 Income PRIDES,  to the Agent accompanied
               by  a  notice to  the Agent,  substantially  in the  form of
               Exhibit B to  the Pledge Agreement, stating that  the Holder
               has transferred  the relevant  amount of Debt  Securities or
               the  appropriate   Applicable  Ownership  Interest   in  the
               Treasury  Portfolio, as the  case may be,  to the Collateral
               Agent and requesting that  the Agent instruct the Collateral
               Agent  to release  the Treasury  Securities underlying  such
               Growth PRIDES, whereupon the  Agent shall promptly give such
               instructions to the  Collateral Agent, substantially in  the
               form of Exhibit A to the Pledge Agreement.  
              

               Upon  receipt of  the  Debt  Securities or  the  appropriate
          Applicable Ownership  Interest in the Treasury  Portfolio, as the
          case  may be,  described  in  clause (a)  or  (b) above  and  the
          instructions described  in clause  (c) above, in  accordance with
          the  terms of  the Pledge  Agreement, the  Collateral Agent  will
          effect  the   release  of   the  Treasury  Securities   having  a
          corresponding aggregate  principal amount from the  Pledge to the
          Agent  free and clear of the Company's security interest therein,
          and upon receipt thereof the Agent shall promptly:
              

                    (i) cancel the  related Growth PRIDES  surrendered
               and transferred;
              

                    (ii)  transfer the  Treasury  Securities that  had
               been components  of such  Growth PRIDES to  the Holder;
               and
              

                    (iii)  authenticate, execute  on  behalf  of  such
               Holder  and   deliver  an  Income   PRIDES  Certificate
               executed by the Company in accordance with the Purchase
               Contract   Agreement  evidencing  the  same  number  of
               Purchase  Contracts as were  evidenced by  the canceled
               Growth PRIDES.
              

               Holders who  elect to separate Treasury  Securities from the
          related Purchase  Contract and  to substitute Debt  Securities or
          the Applicable  Ownership Interest in the  Treasury Portfolio, as
          the  case  may   be,  for  such  Treasury   Securities  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.
              

               A Holder  of Income  PRIDES  may create  or recreate  Growth
          PRIDES by  depositing with  the Collateral Agent  3-Year Treasury
          Securities and  4-Year Treasury Securities,  having an  aggregate
          principal  amount at  maturity equal  to the  aggregate principal
          amount   of  the  Series  D   Notes  and  the   Series  E  Notes,
          respectively,  or, the appropriate  Applicable Ownership Interest
          in the Treasury Portfolio equal to the aggregate principal amount
          of the Pledged  Treasury Securities at maturity,  in exchange for
          the  release  of  such  Pledged Debt  Securities  or  appropriate
          Applicable Ownership  Interest in the Treasury  Portfolio, as the
          case  may  be,  in accordance  with  the  terms  of the  Purchase
          Contract Agreement and the Pledge Agreement.
              

               The Company shall  have the right, at any time  prior to the
          Second Purchase Contract Settlement Date, to defer the payment of
          any or all of the  Contract Adjustment Payments otherwise payable
          on any Payment Date to a date no later than the Purchase Contract
          Settlement Date next succeeding the date such deferral commences,
          but only  if the  Company shall  give the  Holders and the  Agent
          written notice of its election  to defer such payment (specifying
          the amount to be  deferred) as provided in the  Purchase Contract
          Agreement.   In connection with any  Contract Adjustment Payments
          so deferred, additional Contract Adjustment Payments will  accrue
          on  the  amounts so  deferred  at  the rate  of  9.75% per  annum
          (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,  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  Purchase   Contract  Agreement.  No  Contract
          Adjustment Payments may be deferred to  a date that is after  the
          Purchase Contract  Settlement Date next succeeding  the date such
          deferrals commence.
              

               In the event that the Company elects to defer the payment of
          Contract Adjustment Payments on  the Purchase Contracts until the
          next succeeding Purchase Contract  Settlement Date, the Holder of
          this  Growth PRIDES  Certificate  will receive  on such  Purchase
          Contract Settlement Date, in lieu of a cash payment, a  number of
          shares  of  Common Stock  equal to  (x)  the aggregate  amount of
          Deferred Contract  Adjustment Payments  payable to the  Holder of
          the  Growth  PRIDES Certificate  divided  by  (y) the  Applicable
          Market Value related to such Purchase Contract Settlement 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  capital  stock or  make guarantee
          payments with respect to the  foregoing (other than (i) purchases
          or  acquisitions of  shares of  capital stock  of the  Company in
          connection  with   the  satisfaction   by  the  Company   of  its
          obligations  under any  employee or  agent  benefit plans  or the
          satisfaction by the  Company of its  obligations pursuant to  any
          contract  or  security outstanding  on  the  date of  such  event
          requiring  the Company to purchase  its capital stock,  (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 the  Company's capital stock  pursuant to
          the conversion  or exchange  provisions of the  Company's capital
          stock  or  the  security   being  converted  or  exchanged,  (iv)
          dividends or  distributions in capital  stock of the  Company (or
          rights to acquire capital stock) or repurchases or redemptions of
          capital  stock solely  from the issuance  or exchange  of capital
          stock or (v) redemptions or repurchases of any rights outstanding
          under a shareholder rights plan.
              

               The Purchase Contracts and all obligations and rights of the
          Company   and  the   Holders   thereunder,   including,   without
          limitation,  the  rights  of  the  Holders  to  receive  and  the
          obligation of the Company to pay Contract  Adjustment Payments or
          any  Deferred Contract  Adjustment Payments,  and the  rights and
          obligations  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  Second Purchase Contract  Settlement Date, a
          Termination Event shall  have occurred. Upon the occurrence  of a
          Termination Event,  the Company  shall promptly  but in no  event
          later than  two business days  thereafter give written  notice to
          the  Agent, the  Collateral Agent  and to  the Holders,  at their
          addresses  as they appear in the Growth PRIDES Register. Upon and
          after the occurrence of a Termination Event, the Collateral Agent
          shall  release the  Treasury  Securities forming  a  part of  the
          Growth PRIDES evidenced hereby from the Pledge in accordance with
          the provisions of the Pledge Agreement.
              

               Subject to  and upon compliance  with the provisions  of the
          Purchase Contract Agreement, a Holder of Growth PRIDES may settle
          the related Purchase Contracts  in their entirety on or  prior to
          the  second Business  Day  immediately  preceding  each  Purchase
          Contract Settlement  Date, but only  in integral multiples  of 40
          Growth PRIDES. In order to exercise the right to  effect any such
          early  settlement ("an  Early  Settlement") with  respect to  any
          Purchase Contracts  evidenced by this Growth  PRIDES Certificate,
          the  Holder of this Growth  PRIDES Certificate shall deliver this
          Growth PRIDES  Certificate to  the Agent  at the  Corporate Trust
          Office duly endorsed for transfer to the Company or in blank with
          the  form  of  Election to  Settle  Early  set  forth below  duly
          completed and accompanied by  payment in the form of  immediately
          available funds payable  to the order of the Company in an amount
          (the  "Early Settlement Amount") equal  to the sum  of (i)(A) $50
          times the number of Purchase Contracts being settled,  if settled
          on  or prior to the second Business Day immediately preceding the
          First Purchase  Contract Settlement  Date, or  (B) $25 times  the
          number of  Purchase Contracts  being settled, if  settled between
          the  First  Purchase  Contract  Settlement Date  and  the  second
          Business Day  immediately preceding the  Second Purchase Contract
          Settlement  Date, plus in either  case, (ii) if  such delivery is
          made with  respect to  any Purchase  Contracts during  the period
          from the  close of business  on any Record  Date for any  Payment
          Date to the opening of business  on such Payment Date, an  amount
          equal to  the Contract  Adjustment Payments payable,  if any,  on
          such  Payment Date with respect  to such Purchase Contracts. Upon
          Early Settlement of Purchase Contracts by a Holder of the related
          Securities,  the  Pledged  Treasury  Securities  underlying  such
          Securities shall be released  from the Pledge as provided  in the
          Pledge Agreement and the  Holder shall be entitled to  receive, a
          number  of shares  of Common  Stock on  account of  each Purchase
          Contract  forming part  of  a Growth  PRIDES  as to  which  Early
          Settlement  is effected  equal to the applicable Early  Settlement
          Rate which shall be 1.0164 newly issued shares of Common Stock per
          Purchase Contract (the "First Early Settlement Rate") if settled
          prior to the First Purchase Contract Settlement Date, or if
          settled after the First Purchase Contract Settlement Date and
          before the Second Purchase Contract Settlement Date, .5082 newly
          issued shares of Common Stock per Purchase Contract (the "Second
          Early Settlement Rate" and with the First Early Settlement Rate,
          each, an "Early Settlement Rate"); provided however, that upon the
          applicable Early Settlement of the Purchase  Contracts, (i) the
          Holder thereof will  forfeit the right to receive any Deferred
          Contract Adjustment Payments on such  Purchase  Contracts, (ii)
          the  Holder's  right to  receive additional  Contract  Adjustment
          Payments  in  respect  of  such Purchase Contracts  will terminate,
          and (iii)  no adjustment will be made  to or  for the  Holder on
          account of Deferred  Contract Adjustment Payments, or any amount
          accrued in respect of Contract Adjustment Payments. Each Early
          Settlement Rate shall be adjusted in the same manner and at the
          same time as the Settlement Rate is adjusted as provided in the
          Purchase Contract Agreement.
              

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

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

               The  Holder  of  this  Growth  PRIDES  Certificate,  by  its
          acceptance hereof, covenants  and agrees to  treat itself as  the
          owner,  for United  States  federal, state  and local  income and
          franchise tax  purposes, of the Treasury  Securities forming part
          of the Growth PRIDES evidenced hereby.
              

               Subject  to  certain  exceptions,   the  provisions  of  the
          Purchase Contract  Agreement may be  amended with the  consent of
          the  Holders of  a  majority  of  the  Purchase  Contracts.    In
          addition, certain amendments  to the Purchase  Contract Agreement
          may be made without any consent on the Holders as provided in the
          Purchase Contract Agreement.
              

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

               The Company and the  Agent and any agent  of the Company  or
          the Agent may  treat the Person in whose name  this Growth PRIDES
          Certificate is registered  on the Growth  PRIDES Register as  the
          owner  of the Growth PRIDES  evidenced hereby for  the purpose of
          receiving  payments  of  interest  on  the  Treasury  Securities,
          receiving  payments  of  Contract  Adjustment  Payments  and  any
          Deferred  Contract   Adjustment  Payments,  performance   of  the

          or  not  any   payments  in  respect   thereof  be  overdue   and
          notwithstanding  any  notice to  the  contrary,  and neither  the
          Company, the Agent nor any such agent shall be affected by notice
          to the contrary.
              

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

               A  copy of the Purchase  Contract Agreement is available for
          inspection at  the offices of  the Agent during  regular business
          hours of the Agent.
              

               Unless the  certificate of  authentication  hereon has  been
          executed by the  Agent by  manual signature,  this Growth  PRIDES
          Certificate shall not be entitled to any benefit under the Pledge
          Agreement or  the  Purchase Contract  Agreement  or be  valid  or
          obligatory for any purpose.

          PRIDES by the Collateral Agent upon the occurrence of a Tax Event
          Redemption as provided in Section 6.2 and (e) all Proceeds of the
          foregoing (all of the foregoing, collectively, the "Collateral"). 
          Prior to or concurrently with the execution and delivery of this
          Agreement, the Purchase Contract Agent, on behalf of the initial
          Holders of the Securities, shall cause the Debt Securities
          comprising a part of the Income PRIDES, and the Treasury
          Securities comprising a part of the Growth PRIDES, to be
          Transferred to the Collateral Agent for the benefit of the
          Company. Such Debt Securities shall be Transferred by physically
          delivering such Debt Securities to the Collateral Agent endorsed
          in blank and crediting such Debt Securities to the Collateral
          Account.  Treasury Securities and the Treasury Portfolio, as
          applicable, shall be Transferred to the Collateral Account
          maintained by the Collateral Agent at the Securities Intermediary
          by book-entry transfer to the Collateral Account in accordance
          with the TRADES Regulations and other applicable law and by the
          notation by the Securities Intermediary on its books that a
          Security Entitlement with respect to such Treasury Securities or
          Treasury Portfolio, has been credited to the Collateral Account. 
          For purposes of perfecting the Pledge under applicable law,
          including, to the extent applicable, the TRADES Regulations or
          the Uniform Commercial Code as adopted and in effect in any
          applicable jurisdiction, the Collateral Agent shall be the agent
          of the Company as provided herein. The pledge provided in this
          Section 2.1 is herein referred to as the "Pledge" and the Debt
          Securities,  Treasury Securities or Treasury Portfolio subject to
          the Pledge, excluding any Debt Securities or Treasury Securities
          or interest in the Treasury Portfolio released from the Pledge as
          provided in Section 4 hereof, are hereinafter referred to as
          "Pledged Debt Securities", the "Pledged Treasury Securities," or
          Pledged Applicable Ownership Interest in Treasury Portfolio
          respectively and collectively, the "Pledged Securities." Subject
          to the Pledge and the provisions of Section 2.2 hereof, the
          Holders from time to time shall have full beneficial ownership of
          the Collateral.  The Collateral Agent shall have the right to
          have the Debt Securities or any other Securities held in physical
          form reregistered in its name or in the name of its agent or the
          Securities Intermediary.
              

             
                    Except as may be required in order to release Debt
          Securities (or if a Tax Event Redemption has occurred, the
          Applicable Ownership Interest in Treasury Portfolio) or Treasury
          Securities in connection with a Holder's election to convert its
          investment from Income PRIDES to Growth PRIDES, or from Growth
          PRIDES to Income PRIDES, as the case may be, or except as
          otherwise required to release Pledged Securities as specified
          herein, neither the Collateral Agent nor the Securities
          Intermediary shall relinquish physical possession of any
          certificate evidencing Debt Securities (or if a Tax Event
          Redemption has occurred, the Applicable Ownership Interest in
          Treasury Portfolio) or Treasury Securities prior to the
          termination of this Agreement. If it becomes necessary for the
          Collateral Agent to relinquish physical possession of a
          certificate in order to release a portion of the Debt Securities
          evidenced thereby from the Pledge, the Collateral Agent shall use
          its best efforts to obtain physical possession of a replacement
          certificate evidencing any Debt Securities remaining subject to
          the Pledge hereunder registered to it or endorsed in blank within
          [five] days of the date it relinquished possession. The
          Collateral Agent shall promptly notify the Company of its failure
          to obtain possession of any such replacement certificate as
          required hereby.
              

             
               SECTION 2.2.  CONTROL AND PERFECTION.
              

             
                    (a)  In connection with the Pledge granted in Section
               2.1, and subject to the other provisions of this Agreement,
               the Holders from time to time acting through the Purchase
               Contract Agent, as their attorney-in-fact, hereby authorize
               and direct the Securities Intermediary (without the
               necessity of obtaining the further consent of the Purchase
               Contract Agent or any of the Holders), and the Securities
               Intermediary agrees, to comply with and follow any
               instructions and entitlement orders (as defined in Section
               8-102(a)(8) of the Code) that the Collateral Agent on behalf
               of the Company may give in writing with respect to the
               Collateral Account, the Collateral credited thereto and any
               security entitlements with respect to any thereof. Such
               instructions and entitlement orders may, without limitation,
               direct the Securities Intermediary to transfer, redeem,
               sell, liquidate, assign, deliver or otherwise dispose of the
               Treasury Securities, the Treasury Portfolio, and any
               Security Entitlements with respect thereto and to pay and
               deliver any income, proceeds or other funds derived
               therefrom to the Company.  The Purchase Contract Agent and
               the Holders from time to time acting through the Purchase
               Contract Agent each hereby further authorize and direct the
               Collateral Agent, as Agent of the Company, to itself issue
               instructions and entitlement orders, and to otherwise take
               action, with respect to the Collateral Account, the
               Collateral credited thereto and any security entitlements
               with respect thereto, pursuant to the terms and provisions
               hereof, all without the necessity of obtaining the further
               consent of the Purchase Contract Agent or any of the
               Holders. The Collateral Agent shall be the Agent of the
               Company and shall act as directed in writing by the Company.
               Without limiting the generality of the foregoing, the
               Collateral Agent shall issue entitlement orders to the
               Securities Intermediary when and as directed by the Company.
              

             
                    (b)  The Securities Intermediary hereby confirms and
               agrees that: (i) all securities or other property underlying
               any financial assets credited to the Collateral Account
               shall be registered in the name of the Securities
               Intermediary, indorsed to the Securities Intermediary or in
               blank or credited to another Collateral Account maintained
               in the name of the Securities Intermediary and in no case
               will any financial asset credited to the Collateral Account
               be registered in the name of the Purchase Contract Agent,
               the Company or any Holder, payable to the order of, or
               specially indorsed to, the Purchase Contract Agent, the
               Collateral Agent, the Company or any Holder except to the
               extent the foregoing have been specially indorsed to the
               Securities Intermediary or in blank; (ii) all property
               delivered to the Securities Intermediary pursuant to this
               Pledge Agreement (including, without limitation, any Debt
               Securities, the Treasury Portfolio or Treasury Securities)
               will be promptly credited to the Collateral Account; (iii)
               the Collateral Account is an account to which financial
               assets are or may be credited, and the Securities
               Intermediary shall, subject to the terms of this Agreement,
               treat the Purchase Contract Agent as entitled to exercise
               the rights of any financial asset credited to the Collateral
               Account; (iv) the Securities Intermediary has not entered
               into, and until the termination of the this Agreement will
               not enter into, any agreement with any other Person relating
               to the Collateral Account and/or any financial assets
               credited thereto pursuant to which it has agreed to comply
               with entitlement orders (as defined in Section 8-102(a)(8)
               of the Code) of such other Person; and (v) the Securities
               Intermediary has not entered into, and until the termination
               of this Agreement will not enter into, any agreement with
               the Company, the Collateral Agent or the Purchase Contract
               Agent purporting to limit or condition the obligation of the
               Securities Intermediary to comply with entitlement orders as
               set forth in this Section 2.2 hereof.
              

             
                    (c)  The Securities Intermediary hereby agrees that
               each item of property (whether investment property,
               financial asset, security, instrument or cash) credited to
               the Collateral Account shall be treated as a "financial
               asset" within the meaning of Section 8-102(a)(9) of the
               Code. 
              

             
                    (d)  In the event of any conflict between this
               Agreement (or any portion thereof) and any other agreement
               now existing or hereafter entered into, the terms of this
               Agreement shall prevail.
              

             
                    (e)  The Purchase Contract Agent hereby irrevocably
               constitutes and appoints the Collateral Agent and the
               Company, with full power of substitution, as the Purchase
               Contract Agent's attorney-in-fact to take on behalf of, and
               in the name, place and stead of the Purchase Contract Agent
               and the Holders, any action necessary or desirable to
               perfect and to keep perfected the security interest in the
               Collateral referred to in Section 2.1.  The grant of such
               power-of-attorney shall not be deemed to require of the
               Collateral Agent any specific duties or obligations not
               otherwise assumed by the Collateral Agent hereunder. 
              

             
          SECTION 3.     DISTRIBUTIONS ON PLEDGED COLLATERAL.
              

             
                    So long as the Purchase Contract Agent is the
          registered owner of the Pledged Debt Securities, it shall receive
          all payments thereon. If the Pledged Debt Securities are
          reregistered, such that the Collateral Agent becomes the
          registered holder, all payments of principal or interest on, any
          Pledged Securities received by the Collateral Agent that are
          properly payable hereunder shall be paid by the Collateral Agent
          by wire transfer in same day funds:
              

             
                    (i)  In the case of (A) payment of interest with
               respect to the Pledged Debt Securities or cash
               distributions on the appropriate Applicable Ownership
               Interest (as specified in clause (A)(ii) or (B)(ii) of
               the definition of such term) in the Treasury Portfolio,
               as the case may be, and (B) any payments of principal
               with respect to any Debt Securities or the appropriate
               Applicable Ownership Interest (as specified in clause
               (A)(i) or (B)(i) of the definition of such term) in the
               Treasury Portfolio as the case may be, that have been
               released from the Pledge pursuant to Section 4.3
               hereof, to the Purchase Contract Agent, for the benefit
               of the relevant Holders of Securities, to the account
               designated by the Purchase Contract Agent for such
               purpose, no later than 2:00 p.m., New York City time,
               on the Business Day such payment is received by the
               Collateral Agent (provided that in the event such
               payment is received by the Collateral Agent on a day
               that is not a Business Day or after 12:30 p.m., New
               York City time, on a Business Day, then such payment
               shall be made no later than 10:30 a.m., New York City
               time, on the next succeeding Business Day);
              

             
                    (ii) In the case of any principal payments with
               respect to any Treasury Securities that have been
               released from the Pledge pursuant to Section 4.3
               hereof, to the Holders of the Growth PRIDES to the
               accounts designated by them in writing for such purpose
               no later than 2:00 p.m., New York City time, on the
               Business Day such payment is received by the Collateral
               Agent (provided that in the event such payment is
               received by the Collateral Agent on a day that is not a
               Business Day or after 12:30 p.m., New York City time,
               on a Business Day, then such payment shall be made no
               later than 10:30 a.m., New York City time, on the next
               succeeding Business Day); and
              

             
                    (iii)     In the case of payments of the principal
               of any Pledged Debt Securities or on the appropriate
               Applicable Ownership Interest (as specified in clause
               (A)(i) or (B)(i) of the definition of such term) in the
               Treasury Portfolio, as the case may be, or the
               principal of any Pledged Treasury Securities, to the
               Company on the applicable Purchase Contract Settlement
               Date in accordance with the procedure set forth in
               Section 4.6(a) or 4.6(b) hereof, in full satisfaction
               of the respective obligations of the Holders under the
               applicable portion of the related Purchase Contracts.
              

             
          All payments received by the Purchase Contract Agent as provided
          herein shall be applied by the Purchase Contract Agent pursuant
          to the provisions of the Purchase Contract Agreement. If,
          notwithstanding the foregoing, the Purchase Contract Agent shall
          receive any payments of principal on account of any Debt Security
          or, if applicable, the appropriate Applicable Ownership Interest
          (as specified in clause (A)(i) or (B)(i) of the definition of
          such term) that, at the time of such payment, is a Pledged Debt
          Security or the appropriate Applicable Ownership Interest in the
          Treasury Portfolio, as the case may be, or a Holder of a Growth
          PRIDES shall receive any payments of principal on account of any
          Treasury Securities that, at the time of such payment, are
          Pledged Treasury Securities, the Purchase Contract Agent or such
          Holder shall hold the same as trustee of an express trust for the
          benefit of the Company (and promptly deliver the same over to the
          Company) for application to the obligations of the Holders under
          the related Purchase Contracts, and the Holders shall acquire no
          right, title or interest in any such payments of principal so
          received.
              

             
          SECTION 4.     SUBSTITUTION, RELEASE, REPLEDGE AND SETTLEMENT OF
                         DEBT SECURITIES.
              

             
               SECTION 4.1.  SUBSTITUTION FOR DEBT SECURITIES AND THE
                             CREATION OF GROWTH PRIDES.
              

             
                    A Holder of an Income PRIDES may, at any time on or
          prior to the fifth Business Day immediately preceding the Second
          Purchase Contract Settlement Date, create a Growth PRIDES by
          substituting 3-Year Treasury Securities and 4-Year Treasury
          Securities for the Series D Notes and the Series E Notes, or for
          the appropriate Applicable Ownership Interest in the Treasury
          Portfolio, as the case may be, that form a part of such Income
          PRIDES (a "Collateral Substitution") in accordance with this
          Section 4.1 and Section 3.13 of the Purchase Contract Agreement;
          provided, however, that such Collateral Substitutions may not be
          made during the period from the fifth Business Day immediately
          preceding the First Purchase Contract Settlement Date through the
          First Purchase Contract Settlement Date, except that if a Tax
          Event Redemption has occurred and the Treasury Portfolio has
          become a component of the Income PRIDES, Holders of such Income
          PRIDES may make collateral substitutions at any time on or prior
          to the second Business Day immediately preceding the Second
          Purchase Contract Settlement Date (but not during the period from
          the second Business Day immediately preceding the First Purchase
          Contract Settlement Date through the First Purchase Contract
          Settlement Date).  Holders may make Collateral Substitutions (i)
          only in integral multiples of 40 Income PRIDES if Debt Securities
          are being substituted by Treasury Securities, or (ii) only in
          integral multiples of 1,600,000 Income PRIDES if the appropriate
          Applicable Ownership Interests in the Treasury Portfolio are
          being substituted by Treasury Securities.  To create 40 Growth
          PRIDES (if a Tax Event Redemption has not occurred), or 1,600,000
          Growth PRIDES (if a Tax Event Redemption has occurred), the
          Income PRIDES Holder shall
              

             
                    (a)  if a Tax Event Redemption has not occurred, (i)
               prior to the fifth Business Day preceding the First Purchase
               Contract Settlement Date, deposit with the Collateral Agent
               a 3-Year Treasury Security having a principal amount at
               maturity of $1,000 and a 4-Year Treasury Security having a
               principal amount at maturity of $1,000, or (ii) after the
               First Purchase Contract Settlement Date and prior to the
               fifth Business Day preceding the Second Purchase Contract
               Settlement Date, deposit with the Collateral Agent a 4-Year
               Treasury Security having a principal amount at maturity of
               $1,000, or
              

             
                    (b)  if a Tax Event Redemption has occurred, (i) prior
               to the second Business Day immediately preceding the First
               Purchase Contract Settlement Date, deposit with the
               Collateral Agent 3-Year Treasury Securities having an
               aggregate principal amount at maturity of $40,000,000 and 4-
               Year Treasury Securities having an aggregate principal
               amount at maturity of $40,000,000, or (ii) after the First
               Purchase Contract Settlement Date and prior to the second
               Business Day immediately preceding the Second Purchase
               Contract Settlement Date, 4-year Treasury Securities having
               an aggregate principal amount at maturity of $40,000,000,
               and
              

             
                    (c)  in either case, (i) deliver to the Purchase
               Contract Agent cash in an amount equal to the excess of the
               Contract Adjustment Payments that would have accrued on the
               Growth PRIDES being created by the Holder since the last
               Payment Date through the date of Collateral, Substitution,
               over the Contract Adjustment Payments that have accrued over
               the same time period on the Income PRIDES being surrendered
               in connection with such Collateral Substitution, which

               accompanied by a notice to the Purchase Contract Agent,
               substantially in the form of Exhibit B hereto, stating that
               the Holder has transferred the relevant types and amounts of
               Treasury Securities to the Collateral Agent and requesting
               that the Purchase Contract Agent instruct the Collateral
               Agent to release the applicable Debt Securities or the
               appropriate Applicable Ownership Interest in the Treasury
               Portfolio, as the case may be, underlying such Income
               PRIDES, whereupon the Purchase Contract Agent shall promptly
               give such instruction to the Collateral Agent, substantially
               in the form of Exhibit A hereto.
              

             
                    Upon receipt of Treasury Securities described in (a) or
          (b) above, as appropriate from a Holder of Income PRIDES and the
          related instruction from the Purchase Contract Agent described in
          (c) above, the Collateral Agent shall release the Pledged Debt
          Securities or the appropriate Applicable Ownership Interest in
          the Treasury Portfolio, as the case may be, and shall promptly
          Transfer such Pledged Debt Securities or the appropriate
          Applicable Ownership Interest in the Treasury Portfolio, as the
          case may be, free and clear of the lien, pledge or security
          interest created hereby, to the Purchase Contract Agent.
              

             
               SECTION 4.2.  SUBSTITUTION FOR TREASURY SECURITIES AND THE
                             CREATION OF INCOME PRIDES.
              

             
                    A Holder of a Growth PRIDES may, at any time on or
          prior to the fifth Business Day immediately preceding the Second
          Purchase Contract Settlement Date, create Income PRIDES by (a)
          depositing with the Collateral Agent Debt Securities or the
          appropriate Applicable Ownership Interest in the Treasury
          Portfolio, as the case may be, having an aggregate principal
          amount equal to the aggregate principal amount of the Treasury
          Securities comprising part of the Growth PRIDES in accordance
          with this Section 4.2 and Section 3.14 of the Purchase Contract
          Agreement; provided, however, that such Collateral Substitutions
          may not be made during the period from the fifth Business Day
          immediately preceding the First Purchase Contract Settlement Date
          through the First Purchase Contract Settlement Date, except that
          if a Tax Event Redemption has occurred and the Treasury Portfolio
          has become a component of the Income PRIDES, Holders of Growth
          PRIDES may make Collateral Substitutions at any time on or prior
          to the second Business Day immediately preceding the Second
          Purchase Contract Settlement Date (but not during the period from
          the second Business Day immediately preceding the First Purchase
          Contract Settlement Date through the First Purchase Contract
          Settlement Date).  Holders of Growth PRIDES may establish Income
          PRIDES only (i) in integral multiples of 40 Growth PRIDES for 40
          Income PRIDES if a Tax Event Redemption has not occurred, or (ii)
          in integral multiples of 1,600,000 Growth PRIDES for 1,600,000
          Income PRIDES if a Tax Event Redemption has occurred.  To create
          40 Income PRIDES (if a Tax Event Redemption has not occurred), or
          1,600,000 Income PRIDES (if a Tax Event Redemption has occurred),
          the Growth PRIDES Holder shall
              

             
                    (a)  if a Tax Event Redemption has not occurred, (i)
               prior to the fifth Business Day preceding the First Purchase
               Contract Settlement Date, deposit with the Collateral Agent
               $1,000 in aggregate principal amount of Series D Notes and
               $1,000 in aggregate principal amount of Series E Notes, or
               (ii) after the First Purchase Contract Settlement Date,
               deposit with the Collateral Agent $1,000 in aggregate
               principal amount of Series E Notes, or
              

             
                    (b)  if a Tax Event Redemption has occurred, deposit
               with the Collateral Agent the Applicable Ownership Interest
               in Treasury Portfolio for each Income PRIDES being created
               by the Holder, and having an aggregate principal amount of
               $80,000,000, or if after the First Purchase Contract
               Settlement Date, $40,000,000, and
              

             
                    (c)  in either case, transfer and surrender the 40
               related Growth PRIDES, or in the event a Tax Event
               Redemption has occurred, the 1,600,000 related Growth PRIDES
               to the Purchase Contract Agent accompanied by a notice to
               the Purchase Contract Agent, substantially in the form of
               Exhibit B hereto, stating that the Holder has transferred
               the relevant amount of Debt Securities or the appropriate
               Applicable Ownership Interest in the Treasury Portfolio, as
               the case may be, to the Collateral Agent and requesting that
               the Purchase Contract Agent instruct the Collateral Agent to
               release the Treasury Securities underlying such Growth
               PRIDES, whereupon the Purchase Contract Agent shall promptly
               give such instruction to the Collateral Agent, substantially
               in the form of Exhibit A hereto. 
              

             
                    Upon receipt of Debt Securities or the appropriate
          Applicable Ownership Interest in the Treasury Portfolio, as the
          case may be, described in (a) or (b) above, as appropriate from a
          Holder of Growth PRIDES and the related instruction described in
          (c) above from the Purchase Contract Agent, the Collateral Agent
          shall release the related Pledged Treasury Securities and shall
          promptly Transfer such Pledged Treasury Securities, free and
          clear of the lien, pledge or security interest created hereby, to
          the Purchase Contract Agent.
              

             
               SECTION 4.3.  TERMINATION EVENT.
              

             
                    Upon receipt by the Collateral Agent of written notice
          from the Company or the Purchase Contract Agent that there has
          occurred a Termination Event, the Collateral Agent shall release
          all Collateral from the Pledge and shall promptly Transfer any
          Pledged Debt Securities (or the Applicable Ownership Interest in
          the Treasury Portfolio if a Tax Event Redemption has occurred)
          and Pledged Treasury Securities to the Purchase Contract Agent
          for the benefit of the Holders of the Income PRIDES and the
          Growth PRIDES, respectively, free and clear of any lien, pledge
          or security interest or other interest created hereby. 
              

             
                    If such Termination Event shall result from the
          Company's becoming a debtor under the Bankruptcy Code, and if the
          Collateral Agent shall for any reason fail promptly to effectuate
          the release and Transfer of all Pledged Debt Securities, the
          Treasury Portfolio or the Pledged Treasury Securities, as the
          case may be, as provided by this Section 4.3, the Purchase
          Contract Agent shall, upon receipt from the Holders of reasonable
          security or indemnity against the costs, expenses and liabilities
          which might be incurred by it in compliance with this paragraph,
          (i) use its reasonable best efforts to obtain an opinion of a
          nationally recognized law firm reasonably acceptable to the
          Collateral Agent to the effect that, as a result of the Company's
          being the debtor in such a bankruptcy case, the Collateral Agent
          will not be prohibited from releasing or Transferring the
          Collateral as provided in this Section 4.3, and shall deliver
          such opinion to the Collateral Agent within ten days after the
          occurrence of such Termination Event, and if (y) the Purchase
          Contract Agent shall be unable to obtain such opinion within ten
          days after the occurrence of such Termination Event or (z) the
          Collateral Agent shall continue, after delivery of such opinion,
          to refuse to effectuate the release and Transfer of all Pledged
          Debt Securities, the Treasury Portfolio or the Pledged Treasury
          Securities, as the case may be, as provided in this Section 4.3,
          then the Purchase Contract Agent shall within fifteen days after
          the occurrence of such Termination Event commence an action or
          proceeding in the court with jurisdiction of the Company's case
          under the Bankruptcy Code seeking an order requiring the
          Collateral Agent to effectuate the release and transfer of all
          Pledged Debt Securities, the Treasury Portfolio or the Pledged
          Treasury Securities, as the case may be, as provided by this
          Section 4.3 or (ii) commence an action or proceeding in the court
          with jurisdiction of the Company's case under the Bankruptcy Code
          like that described in subsection (i)(z) hereof within ten days
          after the occurrence of such Termination Event.
              

             
               SECTION 4.4.  CASH SETTLEMENT.
              

             
                    (a)  Upon receipt by the Collateral Agent of (i) a
               notice from the Purchase Contract Agent promptly after the
               receipt by the Purchase Contract Agent of such notice that a
               Holder of an Income PRIDES or Growth PRIDES has elected, in
               accordance with the procedures specified in Section
               5.4(a)(i) or (d)(i) of the Purchase Contract Agreement,
               respectively, to settle its Purchase Contract with Cash and
               (ii) payment by such Holder of the amount required to settle
               the applicable portion of such Purchase Contract on or prior
               to 11:00 a.m., New York City time, on the Business Day
               immediately preceding a Purchase Contract Settlement Date in
               lawful money of the United States by certified or cashiers'
               check or wire transfer in immediately available funds
               payable to or upon the order of the Company, then the
               Collateral Agent shall promptly invest any Cash received
               from a Holder in connection with a Cash Settlement in
               Permitted Investments. Upon receipt of the proceeds upon the
               maturity of the Permitted Investments on such Purchase
               Contract Settlement Date, the Collateral Agent shall pay the
               portion of such proceeds and deliver any certified or
               cashiers' checks received, in an aggregate amount equal to
               the Purchase Price, to the Company on such Purchase Contract
               Settlement Date, and shall distribute any funds in respect
               of the interest earned from the Permitted Investments to the
               Purchase Contract Agent for payment to the relevant Holder.
              

             
                    (b)  If in connection with a Purchase Contract
               Settlement Date a Holder of an Income PRIDES (unless a Tax
               Event Redemption has occurred) fails to notify the Purchase
               Contract Agent of its intention to make a Cash Settlement in
               accordance with Section 5.4(a)(i) of the Purchase Contract
               Agreement, such failure shall constitute a default under the
               related Purchase Contract and hereunder, the Holder shall be
               deemed to have consented to the disposition of the Pledged
               Debt Securities pursuant to the remarketing as described in
               Section 5.4(b) of the Purchase Contract Agreement and
               Section 4.4 hereof, which is incorporated herein by
               reference, and the Collateral Agent, for the benefit of the
               Company, will exercise its rights as a secured party with
               respect to applicable Pledged Debt Securities (which shall
               be the Series D Notes in connection with the First Purchase
               Contract Settlement Date and the Series E Notes in
               connection with the Second Purchase Contract Settlement
               Date) at the direction of the Company to cause the
               remarketing of such Pledged Debt Securities.  If a Holder of
               an Income PRIDES (unless of Tax Event Redemption has
               occurred) does notify the Purchase Contract Agent as
               provided in Section 5.4(a)(i) of the Purchase Contract
               Agreement of its intention to make a Cash Settlement, but
               fails to make such payment as required by Section 5.4(a)(ii)
               of the Purchase Contract Agreement, such failure shall
               constitute a default under the related Purchase Contract and
               hereunder, and the applicable Pledged Debt Securities of
               such a Holder will not be remarketed but instead the
               Collateral Agent, for the benefit of the Company, will
               exercise its rights as a secured party with respect to such
               Debt Securities at the direction of the Company to retain or
               dispose of the Collateral in accordance with applicable law.
               In addition, in the event of a Failed Remarketing as
               described in Section 5.4(b) of the Purchase Contract
               Agreement, such Failed Remarketing shall constitute a
               default hereunder by such Holder, and the Collateral Agent,
               for the benefit of the Company, will also exercise its
               rights as a secured party with respect to such Debt
               Securities at the direction of the Company to retain or
               dispose of the Collateral in accordance with applicable law.
              

             
                    (c)  If in connection with a Purchase Contract
               Settlement Date a Holder of a Growth PRIDES or, if a Tax
               Event Redemption has occurred, an Income PRIDES, fails to
               notify the Purchase Contract Agent of such Holder's
               intention to make a Cash Settlement in accordance with
               Section 5.4(d)(i) of the Purchase Contract Agreement, or if
               a Holder of a Growth PRIDES or, if a Tax Event Redemption
               has occurred, an Income PRIDES, notifies the Purchase
               Contract Agent as provided in paragraph 5.4(d)(i) of the
               Purchase Contract Agreement of its intention to make a Cash
               Settlement, but fails to make such payment as required by
               paragraph 5.4(d)(ii) of the Purchase Contract Agreement,
               such failure shall constitute a default under the related
               Purchase Contract and hereunder by such Holder and upon the
               maturity of the related Pledged Treasury Securities or the
               Treasury Portfolio, if any, held by the Collateral Agent on
               the Business Day immediately preceding the Purchase Contract
               Settlement Date, the principal amount of such Pledged
               Treasury Securities or the portion of the Treasury Portfolio
               corresponding to such Purchase Contract received by the
               Collateral Agent shall, upon written direction of the
               Company, be invested promptly in Permitted Investments.  On
               the applicable Purchase Contract Settlement Date, an amount
               equal to the Purchase Price will be remitted to the Company
               as payment thereof. In the event the sum of the proceeds
               from the appropriate related Pledged Treasury Securities or
               Applicable Ownership Interest in the Treasury Portfolio
               (which shall be, in connection with the First Purchase
               Contract Settlement Date, the 3-Year Treasury Securities or
               the portion of the Applicable Ownership Interest in Treasury
               Portfolio (as specified in clause (A) of the definition
               thereof), and in the case of the Second Purchase Contract
               Settlement Date, the 4-Year Treasury Securities or the
               Applicable Ownership Interest in Treasury Portfolio
               (specified in clause (B) of such definition), as the case
               may be, and the investment earnings earned from such
               investments is in excess of the aggregate Purchase Price of
               the Purchase Contracts being settled thereby, the Collateral
               Agent will distribute such excess to the Purchase Contract
               Agent for the benefit of the Holder of the related Growth
               PRIDES or Income PRIDES when received. 
              

             
               (d)  A default by a Holder in the performance of its
               obligations under a Purchase Contract in connection with the
               First Purchase Contract Settlement shall not in itself
               constitute a default in the performance of its obligations
               under such Purchase Contract on the Second Purchase Contract
               Settlement Date (except in connection with Early
               Settlement).  
              

             
                    Series D Notes, 3-Year Treasury Securities and the
               Applicable Ownership Interest in the Treasury Portfolio in
               U.S. Treasury Securities maturing on or prior to August 15,
               2001 are pledged to secure Holder's obligations under the
               Purchase Contracts on the First Purchase Contract Settlement
               Date.  Series E Notes, 4-Year Treasury Securities and the
               Applicable Ownership Interest in the Treasury Portfolio in
               U.S. Treasury Securities maturing on or prior to August 15,
               2002 are pledged to secure such Holders obligations under
               the Purchase Contracts on the Second Purchase Contract
               Settlement Date.  
              

             
                    On the First Purchase Contract Settlement Date, the
               Collateral Agent shall exercise remedies with respect to
               (and have remarketed or otherwise sell in accordance with
               this Agreement) only the Series D Notes, 3-Year Treasury
               Securities (or the corresponding Applicable Ownership
               Interest in the Treasury Portfolio) and associated payments
               and Proceeds; on the Second Purchase Contract Settlement
               Date the Collateral Agent may exercise remedies with respect
               to all then remaining collateral.
              

             
               SECTION 4.5.  EARLY SETTLEMENT.
              

             
                    Upon written notice to the Collateral Agent by the
          Purchase Contract Agent that a Holder of a Security has elected
          to effect Early Settlement of its entire obligation under the
          Purchase Contract forming a part of such Security in accordance
          with the terms of the Purchase Contracts and the Purchase
          Contract Agreement, and that the Purchase Contract Agent has
          received from such Holder, and paid to the Company as confirmed
          in writing by the Company, the related Early Settlement Amount
          pursuant to the terms of the Purchase Contract and the Purchase
          Contract Agreement and that all conditions to such Early
          Settlement have been satisfied, then the Collateral Agent shall
          release from the Pledge, (a) the Pledged Debt Securities or the
          appropriate Applicable Ownership Interest in the Treasury
          Portfolio in the case of a Holder of Income PRIDES or (b) the
          Pledged Treasury Securities in the case of a Holder of Growth
          PRIDES, that had been components of such Security and shall
          Transfer such Pledged Debt Securities or Applicable Ownership
          Interest in the Treasury Portfolio or Pledged Treasury
          Securities, as the case may be, free and clear of the Pledge
          created hereby, to the Purchase Contract Agent for the benefit of
          such Holder.
              

             
               SECTION 4.6.  APPLICATION OF PROCEEDS; SETTLEMENT.
              

             
                    (a)  In connection with a Purchase Contract Settlement
               Date, in the event a Holder of Income PRIDES (if a Tax Event
               Redemption has not occurred) has not elected to make an
               effective Cash Settlement by notifying the Purchase Contract
               Agent in the manner provided for in paragraph 5.4(a)(i) in
               the Purchase Contract Agreement or has not made an Early
               Settlement of the Purchase Contract(s) underlying its Income
               PRIDES, such Holder shall be deemed to have elected to pay
               for the shares of Common Stock to be issued under such
               Purchase Contract(s) from the Proceeds of the related
               Pledged Debt Securities. The Collateral Agent shall, by
               10:00 a.m., New York City time, on the fourth Business Day
               immediately preceding such Purchase Contract Settlement
               Date, without any instruction from such Holder of Income
               PRIDES, present the applicable related Pledged Debt
               Securities (i.e., Series D Notes in the case of the First
               Purchase Contract Settlement Date and Series E Notes in case
               of the Second Purchase Contract Settlement Date) to the
               Remarketing Agent for remarketing. Upon receiving such
               Pledged Debt Securities, the Remarketing Agent, pursuant to
               the terms of the Remarketing Agreement, will use its
               reasonable efforts to remarket such Pledged Debt Securities
               on such date at a price not less than approximately 100.5%
               of the aggregate Value of such Pledged Debt Securities, plus
               accrued and unpaid interest, if any, thereon. After
               deducting as the Remarketing Fee an amount not exceeding 25
               basis points (.25%) of the aggregate Value of the related
               Pledged Debt Securities from any amount of such Proceeds in
               excess of the aggregate Value of the Debt Securities of such
               series, plus such accrued and unpaid interest on the
               remarketed Pledged Debt Securities, the Remarketing Agent
               will remit the entire amount of the Proceeds of such
               remarketing to the Collateral Agent. On the applicable
               Purchase Contract Settlement Date, the Collateral Agent
               shall apply that portion of the Proceeds from such
               remarketing equal to the aggregate Value, plus such accrued
               and unpaid interest of such Pledged Debt Securities, to
               satisfy in full the obligations of such Holders of Income
               PRIDES to pay the Purchase Price on such Purchase Contract
               Settlement Date to purchase the Common Stock under the
               related Purchase Contracts. The remaining portion of such
               Proceeds, if any, shall be distributed by the Collateral
               Agent to the Purchase Contract Agent for payment to the
               Holders. If the Remarketing Agent advises the Collateral
               Agent in writing that it cannot remarket the related Pledged
               Debt Securities of such Holders of Income PRIDES at a price
               not less than 100% of the aggregate Value of such Pledged
               Debt Securities plus any accrued and unpaid interest, or if
               the remarketing does not occur because a condition precedent
               to it has not been fulfilled, thus resulting in a Failed
               Remarketing, the Collateral Agent, for the benefit of the
               Company will, at the written direction of the Company,
               retain or dispose of such Pledged Debt Securities in
               accordance with applicable law and satisfy in full, from any
               such disposition or retention, such Holder's obligation to
               pay the Purchase Price for the Common Stock. 
              

             
                    (b)  In the event a Holder of Growth PRIDES or, if a
               Tax Event Redemption has occurred, Income PRIDES, has not
               made an Early Settlement of the Purchase Contract(s)
               underlying its Growth PRIDES or Income PRIDES, as the case
               may be, such Holder shall be deemed to have elected to pay
               for the shares of Common Stock to be issued under the
               applicable portions of such Purchase Contract(s) from the
               Proceeds of the related Pledged Treasury Securities or the
               Treasury Portfolio, as the case may be. On the Business Day
               immediately prior to a Purchase Contract Settlement Date,
               the Collateral Agent shall, at the written direction of the
               Purchase Contract Agent, invest the Cash proceeds of the
               maturing Pledged Treasury Securities or the Treasury
               Portfolio, as the case may be, in overnight Permitted
               Investments. Without receiving any instruction from any such
               Holder of Growth PRIDES or Income PRIDES, the Collateral
               Agent shall apply the Proceeds of the related Pledged
               Treasury Securities or Treasury Portfolio to the related
               settlement of such Purchase Contracts on the applicable
               Purchase Contract Settlement Date.  In the event the sum of
               the Proceeds from the related Pledged Treasury Securities or
               related Applicable Ownership Interest in the Treasury
               Portfolio and the investment earnings from the investment in
               overnight Permitted Investments is in excess of the
               aggregate Purchase Price of the applicable portions of the
               Purchase Contracts being settled thereby on a Purchase
               Contract Settlement Date, the Collateral Agent shall
               distribute such excess, when received, to the Purchase
               Contract Agent for the benefit of the Holders.
              

             
                    (c)  Pursuant to the Remarketing Agreement, on or prior
               to the fifth Business Day immediately preceding a Purchase
               Contract Settlement Date, but no earlier than the Payment
               Date immediately preceding such Purchase Contract Settlement
               Date, holders of Separate Debt Securities may elect to have
               their Separate Debt Securities of the appropriate series (in
               the case of the First Purchase Contract Settlement Date, the
               Series D Notes, and in the case of the Second Purchase
               Contract Settlement Date, the Series E Notes), remarketed by
               delivering such Separate Debt Securities, together with a
               notice of such election, substantially in the form of
               Exhibit C hereto, to the Custodial Agent. The Custodial
               Agent will hold such Separate Debt Securities in an account
               separate from the Collateral Account. A holder of Separate
               Debt Securities electing to have its Separate Debt
               Securities remarketed will also have the right to withdraw
               such election by written notice to the Custodial Agent,
               substantially in the form of Exhibit D hereto, on or prior
               to the fifth Business Day immediately preceding the
               applicable Purchase Contract Settlement Date, upon which
               notice the Custodial Agent will return such Separate Debt
               Securities to such holder. On the fourth Business Day
               immediately preceding the applicable Purchase Contract
               Settlement Date, the Custodial Agent will deliver to the
               Remarketing Agent for remarketing all Separate Debt
               Securities of the applicable series delivered to the
               Custodial Agent pursuant to this Section 4.6(c) and not
               withdrawn pursuant to the terms hereof prior to such date.
               The portion of the proceeds from such remarketing equal to
               the aggregate Value of such Separate Debt Securities will
               automatically be remitted by the Remarketing Agent to the
               Custodial Agent for the benefit of the holders of such
               Separate Debt Securities. In addition, after deducting as
               the Remarketing Fee an amount not exceeding 25 basis points
               (.25%) of the Value of the remarketed Separate Debt
               Securities, from any amount of such proceeds in excess of
               the aggregate Value of the remarketed Separate Debt
               Securities plus any accrued and unpaid interest thereon, the
               Remarketing Agent will remit to the Custodial Agent the
               remaining portion of the proceeds, if any, for the benefit
               of such holders. If, despite using its reasonable efforts,
               the Remarketing Agent advises the Custodial Agent in writing
               that it cannot remarket the related Separate Debt Securities
               of the applicable series of such holders at a price not less
               than 100% of the aggregate Value of such Separate Debt
               Securities plus accrued and unpaid interest or, if a
               condition to the remarketing shall not have been fulfilled,
               thus in either case resulting in a Failed Remarketing, the
               Remarketing Agent will promptly return such Separate Debt
               Securities to the Custodial Agent for redelivery to such
               holders.
              

             
          SECTION 5.     VOTING RIGHTS -- DEBT SECURITIES.
              

             
                    The Purchase Contract Agent may exercise, or refrain
          from exercising, any and all voting and other consensual rights
          pertaining to the Pledged Debt Securities or any part thereof for
          any purpose not inconsistent with the terms of this Agreement and
          in accordance with the terms of the Purchase Contract Agreement;
          provided, that the Purchase Contract Agent shall not exercise or,
          as the case may be, shall not refrain from exercising such right
          if, in the judgment of the Company, such action would impair or
          otherwise have a material adverse effect on the value of all or
          any of the Pledged Debt Securities; and provided, further, that
          the Purchase Contract Agent shall give the Company and the
          Collateral Agent at least five days' prior written notice of the
          manner in which it intends to exercise, or its reasons for
          refraining from exercising, any such right. Upon receipt of any
          notices and other communications in respect of any Pledged Debt
          Securities, including notice of any meeting at which holders of
          Debt Securities are entitled to vote or solicitation of consents,
          waivers or proxies of holders of Debt Securities, the Collateral
          Agent shall use reasonable efforts to send promptly to the
          Purchase Contract Agent such notice or communication, and as soon
          as reasonably practicable after receipt of a written request
          therefor from the Purchase Contract Agent, execute and deliver to
          the Purchase Contract Agent such proxies and other instruments in
          respect of such Pledged Debt Securities (in form and substance
          satisfactory to the Collateral Agent) as are prepared by the
          Purchase Contract Agent with respect to the Pledged Debt
          Securities.
              

             
          SECTION 6.     RIGHTS AND REMEDIES; TAX EVENT REDEMPTION.
              

             
               SECTION 6.1.  RIGHTS AND REMEDIES OF THE COLLATERAL AGENT.
              

             
                    (a)  In addition to the rights and remedies specified
               in Section 4.4 hereof or otherwise available at law or in
               equity, after an event of default hereunder, the Collateral
               Agent shall have all of the rights and remedies with respect
               to the Collateral of a secured party under the Uniform
               Commercial Code (or any successor thereto) as in effect in
               the State of New York from time to time (the "Code")
               (whether or not the Code is in effect in the jurisdiction
               where the rights and remedies are asserted) and the TRADES
               Regulations and such additional rights and remedies to which
               a secured party is entitled under the laws in effect in any
               jurisdiction where any rights and remedies hereunder may be
               asserted.  Wherever reference is made in this Agreement to
               any section of the Code, such reference shall be deemed to
               include a reference to any provision of the Code which is a
               successor to, or amendment of, such section.  Without
               limiting the generality of the foregoing, such remedies may
               include, to the extent permitted by applicable law, (i)
               retention of the Pledged Debt Securities or other Collateral
               in full satisfaction of the Holders' obligations under the
               Purchase Contracts or (ii) sale of the Pledged Debt
               Securities or other Collateral in one or more public or
               private sales and application of the proceeds in full
               satisfaction of the Holders' obligations under the Purchase
               Contracts.
              

             
                    (b)  Without limiting any rights or powers otherwise
               granted by this Agreement to the Collateral Agent, in the
               event the Collateral Agent is unable to make payments to the
               Company on account of the appropriate Applicable Ownership
               Interest (as specified in clause (A)(i) or B(i) of the
               definition of such term) of the Treasury Portfolio or on
               account of principal payments of any Pledged Treasury
               Securities as provided in Section 3 hereof in satisfaction
               of the obligations of the Holder of the Securities of which
               such Pledged Treasury Securities, or the appropriate
               Applicable Ownership Interest (as specified in clause (A)(i)
               or B(i) of the definition of such term) of the Treasury
               Portfolio, as applicable, is a part under the related
               Purchase Contracts, the inability to make such payments
               shall constitute an event of default hereunder and the
               Collateral Agent shall have and may exercise, with reference
               to such Pledged Treasury Securities, or such appropriate
               Applicable Ownership Interest (as specified in clause (A)(i)
               or B(i) of the definition of such term) of the Treasury
               Portfolio, as applicable, and such obligations of such
               Holder, any and all of the rights and remedies available to
               a secured party under the Code and the TRADES Regulations
               after default by a debtor, and as otherwise granted herein
               or under any other law.
              

             
                    (c)  Without limiting any rights or powers otherwise
               granted by this Agreement to the Collateral Agent, the
               Collateral Agent is hereby irrevocably authorized to receive
               and collect all payments of (i) principal of, or interest
               on, the Pledged Debt Securities, (ii) the principal amount
               of the Pledged Treasury Securities, or (iii) the appropriate
               Applicable Ownership Interest in the Treasury Portfolio,
               subject, in each case, to the provisions of Section 3, and
               as otherwise granted herein.
              

             
                    (d)  The Purchase Contract Agent individually and as
               attorney-in-fact for each Holder of Securities, in the event
               such Holder becomes the Holder of Growth PRIDES, agree that,
               from time to time, upon the written request of the
               Collateral Agent, the Purchase Contract Agent or such Holder
               shall execute and deliver such further documents and do such
               other acts and things as the Collateral Agent may reasonably
               request in order to maintain the Pledge, and the perfection
               and priority thereof, and to confirm the rights of the
               Collateral Agent hereunder. The Purchase Contract Agent
               shall have no liability to any Holder for executing any
               documents or taking any such acts requested by the
               Collateral Agent hereunder, except for liability for its own
               negligent act, its own negligent failure to act or its own
               willful misconduct.
              

             
               SECTION 6.2.  TAX EVENT REDEMPTION.
              

             
                    Upon the occurrence of a Tax Event Redemption prior to
          the Second Purchase Contract Settlement Date, the Collateral
          Agent will, upon the written instruction of the Purchase Contract
          Agent, deliver the Applicable Principal Amount of Pledged Debt
          Securities to the Trustee in exchange for the Redemption Price
          therefor payable on the Tax Event Redemption Date on or prior to
          12:30 p.m., New York City time, such Redemption Price to be paid
          by check or wire transfer in immediately available funds at such
          place and at such account as may be designated by the Collateral
          Agent.  In the event the Collateral Agent receives such
          Redemption Price, the Collateral Agent will, at the written
          direction of the Company, apply an amount equal to the Redemption
          Amount of such Redemption Price to purchase from the Quotation
          Agent, the Treasury Portfolio and promptly remit the remaining
          portion of such Redemption Price to the Purchase Contract Agent
          for payment to the Holders of Income PRIDES.  The Collateral
          Agent shall Transfer the Treasury Portfolio to the Collateral
          Account in the manner specified herein for Pledged Debt
          Securities to secure the obligation of all Holders of  Income
          PRIDES to purchase Common Stock of the Company under the Purchase
          Contracts constituting a part of such Income PRIDES, in
          substitution for the Pledged Debt Securities.  Thereafter the
          Collateral Agent shall have such security interests, rights and
          obligations with respect to the Treasury Portfolio as it had in
          respect of the Pledged Debt Securities, as provided in Sections
          2, 3, 4, 5 and 6, and any reference herein to the Pledged Debt
          Securities shall be deemed to be a reference to such Treasury
          Portfolio.
              

             
               SECTION 6.3.  SUBSTITUTIONS.
              

             
                    Whenever a Holder has the right to substitute Treasury
          Securities, Debt Securities or the appropriate Applicable
          Ownership Interest in the Treasury Portfolio, as the case may be,
          for Collateral held by the Collateral Agent, such substitution
          shall not constitute a novation of the security interest created
          hereby.
              

             
          SECTION 7.     REPRESENTATIONS AND WARRANTIES; COVENANTS.
              

             
               SECTION 7.1.  REPRESENTATIONS AND WARRANTIES.
              

             
                    The Holders from time to time, acting through the
          Purchase Contract Agent as their attorney-in-fact (it being
          understood that the Purchase Contract Agent shall not be liable
          for any representation or warranty made by or on behalf of a
          Holder), hereby represent and warrant to the Collateral Agent,
          which representations and warranties shall be deemed repeated on
          each day a Holder Transfers Collateral that: 
              

             
                    (a)  such Holder has the power to grant a security
               interest in and lien on the Collateral; 
              

             
                    (b)  such Holder is the sole beneficial owner of the
               Collateral and, in the case of Collateral delivered in
               physical form, is the sole holder of such Collateral and is
               the sole beneficial owner of, or has the right to Transfer,
               the Collateral it Transfers to the Collateral Agent, free
               and clear of any security interest, lien, encumbrance, call,
               liability to pay money or other restriction other than the
               security interest and lien granted under Section 2 hereof;
              

             
                    (c)  upon the Transfer of the Collateral to the
               Collateral Account or physical delivery of the Debt
               Securities to the Collateral Agent, the Collateral Agent,
               for the benefit of the Company, will have a valid and
               perfected first priority security interest therein (assuming
               that any central clearing operation or any Intermediary or
               other entity not within the control of the Holder involved
               in the Transfer of the Collateral, including the Collateral
               Agent, gives the notices and takes the action required of it
               hereunder and under applicable law for perfection of that
               interest and assuming the establishment and exercise of
               control pursuant to Section 2.2 hereof); and
              

             
                    (d)  the execution and performance by the Holder of its
               obligations under this Agreement will not result in the
               creation of any security interest, lien or other encumbrance
               on the Collateral other than the security interest and lien
               granted under Section 2 hereof or violate any provision of
               any existing law or regulation applicable to it or of any
               mortgage, charge, pledge, indenture, contract or undertaking
               to which it is a party or which is binding on it or any of
               its assets.
              

             
               SECTION 7.2.  COVENANTS.
              

             
                    The Holders from time to time, acting through the
          Purchase Contract Agent as their attorney-in-fact (it being
          understood that the Purchase Contract Agent shall not be liable
          for any covenant made by or on behalf of a Holder), hereby
          covenant to the Collateral Agent that for so long as the
          Collateral remains subject to the Pledge: 
              

             
                    (a)  neither the Purchase Contract Agent nor such
               Holders will create or purport to create or allow to subsist
               any mortgage, charge, lien, pledge or any other security
               interest whatsoever over the Collateral or any part of it
               other than pursuant to this Agreement; and
              

             
                    (b)  neither the Purchase Contract Agent nor such
               Holders will sell or otherwise dispose (or attempt to
               dispose) of the Collateral or any part of it except for the
               beneficial interest therein, subject to the pledge
               hereunder, transferred in connection with the Transfer of
               the Securities.
              

             
          SECTION 8.     THE COLLATERAL AGENT.
              

             
                    It is hereby agreed as follows:
              

             
               SECTION 8.1.  APPOINTMENT, POWERS AND IMMUNITIES.
              

             
                    The Collateral Agent shall act as Agent for the Company
          hereunder with such powers as are specifically vested in the
          Collateral Agent by the terms of this Agreement, together with
          such other powers as are reasonably incidental thereto. Each of
          the Collateral Agent, the Custodial Agent and the Securities
          Intermediary: (a) shall have no duties or responsibilities except
          those expressly set forth in this Agreement and no implied
          covenants or obligations shall be inferred from this Agreement
          against any of them, nor shall any of them be bound by the
          provisions of any agreement by any party hereto beyond the
          specific terms hereof; (b) shall not be responsible for any
          recitals contained in this Agreement, or in any certificate or
          other document referred to or provided for in, or received by it
          under, this Agreement, the Securities or the Purchase Contract
          Agreement, or for the value, validity, effectiveness,
          genuineness, enforceability or sufficiency of this Agreement
          (other than as against the Collateral Agent), the Securities or
          the Purchase Contract Agreement or any other document referred to
          or provided for herein or therein or for any failure by the
          Company or any other Person (except the Collateral Agent, the
          Custodial Agent or the Securities Intermediary, as the case may
          be) to perform any of its obligations hereunder or thereunder or
          for the perfection, priority or, except as expressly required
          hereby, maintenance of any security interest created hereunder;
          (c) shall not be required to initiate or conduct any litigation
          or collection proceedings hereunder (except in the case of the
          Collateral Agent, pursuant to directions furnished under Section
          8.2 hereof, subject to Section 8.6 hereof); (d) shall not be
          responsible for any action taken or omitted to be taken by it
          hereunder or under any other document or instrument referred to
          or provided for herein or in connection herewith or therewith,
          except for its own negligence or willful misconduct; and (e)
          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 Securities or other property deposited hereunder.
          Subject to the foregoing, during the term of this Agreement, the
          Collateral Agent shall take all reasonable action in connection
          with the safekeeping and preservation of the Collateral
          hereunder.
              

             
                    No provision of this Agreement shall require the
          Collateral Agent, the Custodial Agent or the Securities
          Intermediary to expend or risk its own funds or otherwise incur
          any financial liability in the performance of any of its duties
          hereunder. In no event shall the Collateral Agent, the Custodial
          Agent or the Securities Intermediary be liable for any amount in
          excess of the Value of the Collateral. Notwithstanding the
          foregoing, the Collateral Agent, the Custodial Agent and
          Securities Intermediary, each in its individual capacity, hereby
          waive any right of setoff, bankers lien, liens or perfection
          rights as securities intermediary or any counterclaim with
          respect to any of the Collateral.
              

             
               SECTION 8.2.  INSTRUCTIONS OF THE COMPANY.
              

             
                    The Company shall have the right, by one or more
          instruments in writing executed and delivered to the Collateral
          Agent, the Custodial Agent or the Securities Intermediary, as the
          case may be, to direct the time, method and place of conducting
          any proceeding for the realization of any right or remedy
          available to the Collateral Agent, or of exercising any power
          conferred on the Collateral Agent, the Custodial Agent or the
          Securities Intermediary, as the case may be, or to direct the
          taking or refraining from taking of any action authorized by this
          Agreement; provided, however, that (i) such direction shall not
          conflict with the provisions of any law or of this Agreement and
          (ii) the Collateral Agent, the Custodial Agent and the Securities
          Intermediary shall be adequately indemnified as provided herein.
          Nothing in this Section 8.2 shall impair the right of the
          Collateral Agent in its discretion to take any action or omit to
          take any action which it deems proper and which is not
          inconsistent with such direction.
              

             
               SECTION 8.3.  RELIANCE BY COLLATERAL AGENT.
              

             
                    Each of the Securities Intermediary, the Custodial
          Agent and the Collateral Agent shall be entitled conclusively to
          rely upon any certification, order, judgment, opinion, notice or
          other communication (including, without limitation, any thereof
          by telephone, telecopy, telex or facsimile) 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), and upon
          advice and statements of legal counsel and other experts selected
          by the Collateral Agent, the Custodial Agent or the Securities
          Intermediary, as the case may be. As to any matters not expressly
          provided for by this Agreement, the Collateral Agent, the
          Custodial Agent and the Securities Intermediary shall in all
          cases be fully protected in acting, or in refraining from acting,
          hereunder in accordance with instructions given by the Company in
          accordance with this Agreement.
              

             
               SECTION 8.4.  RIGHTS IN OTHER CAPACITIES.
              

             
                    The Collateral Agent, the Custodial Agent and the
          Securities Intermediary and their affiliates may (without having
          to account therefor to the Company) accept deposits from, lend
          money to, make their investments in and generally engage in any
          kind of banking, trust or other business with the Purchase
          Contract Agent and any Holder of Securities (and any of their
          respective subsidiaries or affiliates) as if it were not acting
          as the Collateral Agent, the Custodial Agent or the Securities
          Intermediary, as the case may be, and the Collateral Agent, the
          Custodial Agent and the Securities Intermediary and their
          affiliates may accept fees and other consideration from the
          Purchase Contract Agent and any Holder of Securities without
          having to account for the same to the Company; provided that each
          of the Securities Intermediary, the Custodial Agent and the
          Collateral Agent covenants and agrees with the Company that it
          shall not accept, receive or permit there to be created in favor
          of itself and shall take no affirmative action to permit there to
          be created in favor of any other Person, any security interest,
          lien or other encumbrance of any kind in or upon the Collateral.
              

             
               SECTION 8.5.  NON-RELIANCE ON COLLATERAL AGENT.
              

             
                    None of the Securities Intermediary, the Custodial
          Agent or the Collateral Agent shall be required to keep itself
          informed as to the performance or observance by the Purchase
          Contract Agent or any Holder of Securities of this Agreement, the
          Purchase Contract Agreement, the Securities or any other document
          referred to or provided for herein or therein or to inspect the
          properties or books of the Purchase Contract Agent or any Holder
          of Securities. The Collateral Agent, the Custodial Agent and the
          Securities Intermediary shall not have any duty or responsibility
          to provide the Company with any credit or other information
          concerning the affairs, financial condition or business of the
          Purchase Contract Agent or any Holder of Securities (or any of
          their respective affiliates) that may come into the possession of
          the Collateral Agent, the Custodial Agent or the Securities
          Intermediary or any of their respective affiliates. 
              

             
               SECTION 8.6.  COMPENSATION AND INDEMNITY.
              

             
                    The Company agrees: (i) to pay each of the Collateral
          Agent and the Custodial Agent from time to time such compensation
          as shall be agreed in writing between the Company and the
          Collateral Agent or the Custodial Agent, as the case may be, for
          all services rendered by each of them hereunder and (ii) to
          indemnify the Collateral Agent, the Custodial Agent and the
          Securities Intermediary for, and to hold each of them harmless
          from and against, any loss, liability or reasonable out-of-pocket
          expense incurred without negligence, willful misconduct or bad
          faith on its part, arising out of or in connection with the
          acceptance or administration of its powers and duties under this
          Agreement, including the reasonable out-of-pocket costs and
          expenses (including reasonable fees and  expenses of counsel) of
          defending itself against any claim or liability in connection
          with the exercise or performance of such powers and duties.  The
          Collateral Agent, the Custodial Agent and the Securities
          Intermediary shall each promptly notify the Company of any third
          party claim which may give rise to 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.
              

             
               SECTION 8.7.  FAILURE TO ACT.
              

             
                    In the event of any ambiguity in the provisions of this
          Agreement or any dispute between or conflicting claims by or
          among the parties hereto or any other Person with respect to any
          funds or property deposited hereunder, the Collateral Agent and
          the Custodial Agent shall be entitled, after prompt notice to the
          Company and the Purchase Contract Agent, at its sole option, to
          refuse to comply with any and all claims, demands or instructions
          with respect to such property or funds so long as such dispute or
          conflict shall continue, and neither the Collateral Agent nor the
          Custodial Agent shall 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 Collateral Agent
          and the Custodial 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, satisfactory to the Collateral Agent or
          the Custodial Agent, as the case may be, or (ii) the Collateral
          Agent or the Custodial Agent, as the case may be, shall have
          received security or an indemnity satisfactory to the Collateral
          Agent or the Custodial Agent, as the case may be, sufficient to
          save the Collateral Agent or the Custodial Agent, as the case may
          be, harmless from and against any and all loss, liability or
          reasonable out-of-pocket expense which the Collateral Agent or
          the Custodial Agent, as the case may be, may without negligence,
          willful misconduct, or bad faith on its part incur by reason of
          its acting. The Collateral Agent or the Custodial Agent may in
          addition elect to commence an interpleader action or seek other
          judicial relief or orders as the Collateral Agent or the
          Custodial Agent, as the case may be, may deem necessary.
          Notwithstanding anything contained herein to the contrary,
          neither the Collateral Agent nor the Custodial Agent shall be
          required to take any action that is in its opinion contrary to
          law or to the terms of this Agreement, or which would in its
          opinion subject it or any of its officers, employees or directors
          to liability.
              

             
               SECTION 8.8.  RESIGNATION OF COLLATERAL AGENT.
              

             
                    Subject to the appointment and acceptance of a
          successor Collateral Agent or Custodial Agent as provided below,
          (a) the Collateral Agent and the Custodial Agent may resign at
          any time by giving notice thereof to the Company and the Purchase
          Contract Agent as attorney-in-fact for the Holders of Securities,
          (b) the Collateral Agent and the Custodial Agent may be removed
          at any time by the Company and (c) if the Collateral Agent or the
          Custodial Agent fails to perform any of its material obligations
          hereunder in any material respect for a period of not less than
          20 days after receiving written notice of such failure by the
          Purchase Contract Agent and such failure shall be continuing, the
          Collateral Agent or the Custodial Agent may be removed by the
          Purchase Contract Agent. The Purchase Contract Agent shall
          promptly notify the Company of any removal of the Collateral
          Agent pursuant to clause (c) of the immediately preceding
          sentence. Upon any such resignation or removal, the Company shall
          have the right to appoint a successor Collateral Agent or
          Custodial Agent, as the case may be. If no successor Collateral
          Agent or Custodial Agent, as the case may be, shall have been so
          appointed and shall have accepted such appointment within 30 days
          after the retiring Collateral Agent's or Custodial Agent's giving
          of notice of resignation or such removal, then the retiring
          Collateral Agent or Custodial Agent, as the case may be, may
          petition any court of competent jurisdiction for the appointment
          of a successor Collateral Agent or Custodial Agent, as the case
          may be. Each of the Collateral Agent and the Custodial Agent
          shall be a bank which has an office in New York, New York with a
          combined capital and surplus of at least $75,000,000. Upon the
          acceptance of any appointment as Collateral Agent or Custodial
          Agent, as the case may be, hereunder by a successor Collateral
          Agent or Custodial Agent, as the case may be, such successor
          shall thereupon succeed to and become vested with all the rights,
          powers, privileges and duties of the retiring Collateral Agent or
          Custodial Agent, as the case may be, and the retiring Collateral
          Agent or Custodial Agent, as the case may be, shall take all
          appropriate action to transfer any money and property held by it
          hereunder (including the Collateral) to such successor. The
          retiring Collateral Agent or Custodial Agent shall, upon such
          succession, be discharged from its duties and obligations as
          Collateral Agent or Custodial Agent hereunder. After any retiring
          Collateral Agent's or Custodial Agent's resignation hereunder as
          Collateral Agent or Custodial Agent, the provisions of this
          Section 8 shall continue in effect for its benefit in respect of
          any actions taken or omitted to be taken by it while it was
          acting as the Collateral Agent or Custodial Agent. Any
          resignation or removal of the Collateral Agent hereunder shall be
          deemed for all purposes of this Agreement as the simultaneous
          resignation or removal of the Custodial Agent and the Securities
          Intermediary.
              

             
               SECTION 8.9.  RIGHT TO APPOINT AGENT OR ADVISOR.
              

             
                    The Collateral Agent shall have the right to appoint
          agents or advisors in connection with any of its duties
          hereunder, and the Collateral Agent shall not be liable for any
          action taken or omitted by, or in reliance upon the advice of,
          such agents or advisors selected in good faith. The appointment
          of agents pursuant to this Section 8.9 shall be subject to prior
          consent of the Company, which consent shall not be unreasonably
          withheld.
              

             
               SECTION 8.10.  SURVIVAL.
              

             
                    The provisions of this Section 8 shall survive
          termination of this Agreement and the resignation or removal of
          the Collateral Agent or the Custodial Agent.
              

             
               SECTION 8.11.  EXCULPATION.
              

             
                    Anything in this Agreement to the contrary
          notwithstanding, in no event shall any of the Collateral Agent,
          the Custodial Agent or the Securities Intermediary or their

                    (1)  to evidence the succession of another Person to
               the Company, and the assumption by any such successor of the

                    (2)  to add to the covenants of the Company for the
               benefit of the Holders, or to surrender any right or power
               herein conferred upon the Company so long as such covenants
               or such surrender do not adversely affect the validity,
               perfection or priority of the security interests granted or
               created hereunder; or

               under this Agreement, provided such action shall not
               adversely affect the interests of the Holders.
              

             
               SECTION 9.2.  AMENDMENT WITH CONSENT OF HOLDERS.
              

             
                    With the consent of the Holders of not less than a
          majority of the Purchase Contracts at the time outstanding, by
          Act of said Holders delivered to the Company, the Purchase
          Contract Agent or the Collateral Agent, as the case may be, the
          Company, the Purchase Contract Agent, the Collateral Agent, the
          Custodial Agent and the Securities Intermediary may amend this
          Agreement for the purpose of modifying in any manner the
          provisions of this Agreement or the rights of the Holders in
          respect of the Securities; provided, however, that no such
          supplemental agreement shall, without the consent of the Holder
          of each Outstanding Security adversely affected thereby,
              

             
                    (1)  change the amount or type of Collateral underlying
               a Security (subject to the  rights of Holders to make
               Collateral Substitutions as contemplated by Sections 4.1 and
               4.2),  impair the right of the Holder of any Security to
               receive distributions on the underlying Collateral or
               otherwise adversely affect the Holder's rights in or to such
               Collateral; or
              

             
                    (2)  otherwise effect any action that would require the
               consent of the Holder of each Outstanding Security affected
               thereby pursuant to the Purchase Contract Agreement if such
               action were effected by an agreement supplemental thereto;
               or
              

             
                    (3)  reduce the percentage of Purchase Contracts the
               consent of whose Holders is required for any such amendment.
              

             
          It shall not be necessary for any Act of Holders under this
          Section to approve the particular form of any proposed amendment,
          but it shall be sufficient if such Act shall approve the
          substance thereof.
              

             
               SECTION 9.3.  EXECUTION OF AMENDMENTS.

          Collateral Agent, and Section 7.1 of the Purchase Contract
          Agreement, with respect to the Purchase Contract Agent) shall be
          fully protected in relying upon, an Opinion of Counsel stating
          that the execution of such amendment is authorized or permitted
          by this Agreement and that all conditions precedent, if any, to
          the execution and delivery of such amendment have been satisfied.
              

             
               SECTION 9.4.  EFFECT OF AMENDMENTS.

          9, this Agreement shall be modified in accordance therewith, and
          such amendment shall form a part of this Agreement for all
          purposes; and every Holder of Certificates theretofore or
          thereafter authenticated, executed on behalf of the Holders and

          in form approved by the Purchase Contract Agent and the
          Collateral Agent as to any matter provided for in such amendment.
          If the Company shall so determine, new Security Certificates so
          modified as to conform, in the opinion of the Collateral Agent,
          the Purchase Contract Agent and the Company, to any such
          amendment may be prepared and executed by the Company and
          authenticated, executed on behalf of the Holders and delivered by
          the Purchase Contract Agent in accordance with the Purchase

          Certificates.

                    No failure on the part of the Collateral Agent or any
          of its agents to exercise, and no course of dealing with respect
          to, and no delay in exercising, any right, power or remedy
          hereunder shall operate as a waiver thereof; nor shall any single
          or partial exercise by the Collateral Agent or any of its agents
          of any right, power or remedy hereunder preclude any other or
          further exercise thereof or the exercise of any other right,
          power or remedy. The remedies herein are cumulative and are not
          exclusive of any remedies provided by law.
              

             
               SECTION 10.2.  GOVERNING LAW.
              

             
                    THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN

          time to time of the Securities, acting through the Purchase
          Contract Agent as their attorney-in-fact, irrevocably waive, to
          the fullest extent permitted by applicable law, any objection
          which they may now or hereafter have to the laying of the venue
          of any such proceeding brought in such a court and any claim that
          any such proceeding brought in such a court has been brought in
          an inconvenient forum.
              

             
               SECTION 10.3.  NOTICES.

                    If any provision hereof is invalid and unenforceable in
          any jurisdiction, then, to the fullest extent permitted by law,
          (i) the other provisions hereof shall remain in full force and
          effect in such jurisdiction and shall be liberally construed in
          order to carry out the intentions of the parties hereto as nearly
          as may be possible and (ii) the invalidity or unenforceability of
          any provision hereof in any jurisdiction shall not affect the
          validity or enforceability of such provision in any other
          jurisdiction.

          enforcement of this Section 10.7; and (c) all transfer, stamp,
          documentary or other similar taxes, assessments or charges levied
          by any governmental or revenue authority in respect of this
          Agreement or any other document referred to herein and all costs,
          expenses, taxes, assessments and other charges incurred in
          connection with any filing, registration, recording or perfection
