premium, if any, and interest, if any, on the 2037 Debentures shall be paid in
immediately available funds to the Depositary (as defined below) or a nominee of
the Depositary.  If at any time the 2037 Debentures are no longer represented by

accordance with its normal procedures.  Payments of interest with respect to
Certificated 2037 Debentures other than at Maturity may, at the option of the
Company, be made by check mailed to the address of the Person entitled thereto
as it appears on the Security Register on the relevant Regular Record Date or by
wire transfer in same day funds to such account as may have been appropriately
designated to the Paying Agent by such Person in writing not later than such
relevant Regular Record Date.  Each payment of principal, premium, if any, and
interest, if any, shall be made 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. Transfer of the 2037 Debentures shall be registrable on the
Securities Register upon the surrender of the 2037 Debentures for registration
of transfer at the office or agency maintained by the Company in the Borough of
Manhattan, The City of New York (which shall initially be the office of First

Redemption Date, at the option of the Company at any time, as a whole or in
part, at a Redemption Price equal to the greater of (i) 100% of their principal
amount, plus accrued interest to the Redemption Date, (ii) the sum of the
present values of the remaining scheduled payments of principal and interest
thereon discounted to the Redemption Date on a semiannual basis (assuming a 360-
day year consisting of twelve 30-day months) at the Treasury Yield plus ten (10)
basis points, calculated as if the principal amount were payable in full on
March 1, 2009, or (iii) the sum of the present values of the remaining scheduled
payments of principal and interest thereon discounted to the Redemption Date on
a semiannual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Yield plus ten (10) basis points.

          "Treasury Yield" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

                                      -12-

 
          "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the 2037 Debentures (determined as if the 2037 Debentures
mature on March 1, 2009 for the purposes of clause (ii) of the first paragraph
of this Section 7) that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of corporate
debt securities of comparable maturity to the remaining term of the 2037
Debentures (determined as if the 2037 Debentures mature on March 1, 2009 for the
purposes of clause (ii) of the first paragraph of this Section 7).  For purposes
of clause (iii) of the first paragraph of this Section 7, prior to 2008 the
Comparable Treasury Issue shall be deemed to be the most recently issued 30-year
United States Treasury security.  "Independent Investment Banker" means Morgan
Stanley & Co. Incorporated or, if such firm is unwilling or unable to select the
Comparable Treasury Issue, another independent investment banking institution of
national standing appointed by the Trustee.

Business Day preceding such Redemption Date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such Business Day, (A) the average
of the Reference Treasury Dealer Quotations for such Redemption Date, after
excluding the highest and lowest such Reference Treasury Dealer Quotations, or
(B) if the Trustee obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Quotations.  "Reference Treasury Dealer
Quotations" means, with respect to each Reference Treasury Dealer and any
Redemption Date, the average as determined by the Trustee of the bid and asked

Date.

          "Reference Treasury Dealer" means (i) each of Morgan Stanley & Co.
Incorporated and  Goldman, Sachs & Co. and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), the
Company shall substitute therefor another Primary Treasury Dealer; and (ii) any
other Primary Treasury Dealer selected by the Trustee after consultation with
the Company.

     In the event that the Company elects to redeem the 2037 Debentures at a
Redemption Price determined as provided in clause (ii) of the first paragraph of
this Section 7, the Trustee shall, instead of specifying the Redemption Price in
such redemption notice, specify the manner in which the Redemption Price shall
be calculated under this Section 7 and provide a numerical example of such
calculation in the manner set forth above using the date of the notice of
redemption instead of the Redemption Date.

     8.   The 2037 Debentures are not subject to any sinking fund or analogous
provisions.

     The 2037 Debentures will be redeemable on March 1, 2009, at the option of
the Holders thereof, at 100% of their principal amount, together with interest
payable to the Repayment Date. Less than the entire principal amount of any 2037
Debenture may be redeemed, provided the principal amount which is to be redeemed
is equal to $1,000 or an integral of $1,000.

     So long as the 2037 Debentures shall be issued in the form of a Global 2037
Debenture, the Depositary or its nominee, as registered holder of the 2037
Debentures, will be entitled to tender the 2037 Debentures on March 1, 2009 for
repayment.  During the period from and including January 1, 2009 to and
including February 1, 2009, the Depositary will receive instructions from its
participants (acting on behalf of owners of beneficial interests in the 2037
Debentures) to tender the 2037 Debentures for repayment under the Depositary's
procedures.  Such tenders for repayment will be made by the Depositary, provided
that the Depositary receives instructions from tendering participants by Noon on
February 1, 2009.  The Depositary will notify the Paying Agent designated
pursuant to the Indenture by the close of business on February 1, 2009 as to the
aggregate principal amount of the 2037 Debentures, if any, for which the
Depositary shall have received instructions to tender for repayments.

     If at any time the 2037 Debentures are no longer represented by the Global
2037 Debenture and are issued in the form of Certificated 2037 Debentures,
tenders for repayment of any 2037 Debenture on March 1, 2009 shall be made in

shall be irrevocable.  All questions as to the validity, eligibility (including
time of receipt) and the acceptance of any 2037 Debenture for repayment will be
