     James G. Reynolds and Devasis Ghose do hereby certify that we are the duly
elected Executive Vice President and Chief Financial Officer, and Senior Vice

attached hereto as Exhibit A, a series of Securities of the Company shall be
established pursuant to Section 301 of the Indenture dated as of September 1,
1993 (the "Indenture") between the Company and The Bank of New York, as Trustee,
and that said series shall have the following terms and provisions:

          (i)    the title of such series of Securities shall be 6.45% Senior
     Notes due June 25, 2012 (referred to herein as the "Notes");

          (ii)   the Notes which may be authenticated and delivered under the
     Indenture shall be limited to $250,000,000 aggregate principal amount
     (except as otherwise provided in Sections 304, 306, 906 or 1107 of the
     Indenture); however, from time to time, without giving notice or seeking
     consent of holders of the Notes, the Company may issue additional notes
     having the same ranking, interest rate, and maturity and other terms as the
     Notes;

          (iii)  the Notes shall be issued as Registered Securities only,
     without coupons, and beneficial interests in the Notes may be acquired or
     subsequently transferred, only in denominations of $1,000 or in any amount
     in excess thereof which is an integral multiple or $1,000;

          (iv)   the Notes shall be issued in the form of a permanent global
     certificate dated June 25, 2002;

          (v)    the principal amount of the Notes shall be payable on June 25,
     2012;

          (vi)   interest on the Notes shall accrue at a fixed rate of interest
     as more fully described in the attached form of Notes; the Notes will bear
     interest from June 25, 2002, and such interest will be payable
     semi-annually on June 25 and December 25 of each year (or, if such date is
     not a Business Day, on the next Business Day thereafter), commencing on
     December 25, 2002 (each, an "Interest Payment Date"); the Regular Record
     Dates with respect to the Notes shall be each June 10 and December 10,
     respectively, whether or not a Business Day, preceding the relevant
     Interest Payment Date; interest on the Notes will be calculated on the
     basis of a 360-day year of twelve 30-day months;

          (vii)  principal and interest payable with respect to the Notes shall
     be payable at the Corporate Trust Office of The Bank of New York, located
     at 101 Barclay Street, Floor 21W, New York, New York 10286;



          (viii) the Notes are not subject to redemption, in whole or in part,
     at the option of the Company and the Notes are not subject to any sinking
     fund; and

          (ix)   The notes shall be issued in the form of one Book-Entry
     Security, and the Depository for such Notes shall be The Depository Trust
     Company or its nominee, and the beneficial owners of interests in such
     Book-Entry Security may not exchange any such interests (except as provided
     by Section 305 of the Indenture).

     We further certify, having read the Indenture, including Sections 303 and
501 thereof, and the definitions in the Indenture relating thereto and certain
other corporate documents and records, having made such examination or
investigation as we deemed necessary to enable us to express an informed
opinion, that all conditions precedent to the authentication and delivery of the
Notes have been complied with and, to the best of our knowledge, no event which
is, or after notice or lapse of time would become, an Event of Default with
respect to any of the Securities has occurred and is continuing.

     Capitalized terms used herein that are not otherwise defined shall have the
meanings ascribed thereto in the Indenture.

     IN WITNESS WHEREOF, the undersigned have executed this Officers'
Certificate as of the 25th day of June, 2002.
