(herein called the "NOTES"), issued and to be issued under an Indenture dated as
of August 17, 1998, as supplemented by the Seventh Supplemental Indenture, dated

"INDENTURE"), between the Company and The Bank of New York, as trustee (the

                                   DEFINITIONS

     The following terms, as used herein, have the following meanings unless the
context or use clearly indicates another or different meaning or intent:

     "ADJUSTED TREASURY RATE" means, with respect to any redemption date:

     (i)  the yield, under the heading which represents the average for the
          immediately preceding week, appearing in the most recently published
          statistical release designated "H.15(519)" or any successor
          publication which is published weekly by the Board of Governors of the
          Federal Reserve System and which establishes yields on actively traded
          United States Treasury securities adjusted to constant maturity under
          the caption "Treasury Constant Maturities," for the maturity
          corresponding to the Comparable Treasury Issue (if no maturity is
          within three months before or after the Remaining Life, as defined
          below, yields for the two published maturities most closely
          corresponding to the Comparable Treasury Issue will be determined and
          the Adjusted Treasury Rate will be interpolated or extrapolated from
          such yields on a straight line basis, rounding to the nearest month);
          or

     (ii) if such release (or any successor release) is not published during the
          week preceding the calculation date or does not contain such yields,
          the rate per annum equal to the semi-annual equivalent yield to
          maturity of the Comparable Treasury Issue, calculated using 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.

The Adjusted Treasury Rate will be calculated on the third Business Day
preceding the redemption date.

     "BUSINESS DAY" shall mean any day other than a Saturday or Sunday that is
neither a legal holiday nor a day on which banking institutions are authorized
or required by law or regulations to close in the City of New York.

                                       4
<PAGE>

     "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 Notes to be redeemed that would be used, 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 such Notes (the "REMAINING LIFE").

     "COMPARABLE TREASURY PRICE" means (1) the average of five Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest Reference Treasury Dealer Quotations, or (2) if an Independent
Investment Banker obtains fewer than five such Reference Treasury Dealer
Quotations, the average of all such quotations.

depositary.

     "INDEPENDENT INVESTMENT BANKER" means any of Banc of America Securities
LLC, BNY Capital Markets, Inc., Credit Suisse First Boston Corporation or
Salomon Smith Barney Inc. or any of their respective successors, as designated
by the Company, or if all of the firms are unwilling or unable to serve as such,
an independent investment and banking institution of national standing appointed
by the Company.

     "INTEREST PAYMENT DATE" shall mean the date on which interest on this Note
is paid, which date(s) are set forth on the face of this Note.

     "REFERENCE TREASURY DEALER" means:

     (i)  Banc of America Securities LLC, BNY Capital Markets, Inc., Credit
          Suisse First Boston Corporation, Salomon Smith Barney Inc. and each of
          their respective successors; provided that, if any such Reference
          Treasury Dealer ceases to be a primary U.S. Government securities
          dealer in New York City ("Primary Treasury Dealer"), the Company will
          substitute another Primary Treasury Dealer; and

     (ii) one other Primary Treasury Dealer selected by the Company.

     "REFERENCE TREASURY DEALER QUOTATIONS" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
an Independent Investment Banker, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to an Independent Investment Banker at 5:00 p.m., New York
City time, on the third Business Day preceding such redemption date.

                                  INTEREST RATE

     This Note will bear interest at the rate per annum (computed based on a
360-day year consisting of twelve 30-day months) identified on the face of this
Note.

                               OPTIONAL REDEMPTION

     The Notes are subject to redemption, in whole or in part, at any time, and
at the option of the Company, at a redemption price equal to the greater of:

                                       5
<PAGE>

     (i)  100% of the principal amount of Notes then outstanding to be redeemed,
          or

     (ii) the sum of the present values of the remaining scheduled payments of
          principal and interest on the Notes then outstanding to be redeemed
          (not including any portion of such payments of interest accrued as of
          the redemption date) discounted to the redemption date on a semiannual
          basis (computed based on a 360-day year consisting of twelve 30-day
          months) at the Adjusted Treasury Rate, plus 25 basis points (0.25%),
          as calculated by an Independent Investment Banker,

plus, in both of the above cases, accrued and unpaid interest thereon to the
redemption date.

     The Company will mail a notice of redemption at least 30 days but no more
than 60 days before the redemption date to each holder of Notes to be redeemed.
If the Company elects to partially redeem the Notes, the Trustee will select in
a fair and appropriate manner the Notes to be redeemed.

     Unless the Company defaults in payment of the redemption price, on and
after the redemption date, interest will cease to accrue on the Notes or
portions thereof called for redemption.

     The Notes are not entitled to the benefit of any sinking fund or analogous
provision.

(herein called the "NOTES"), issued and to be issued under an Indenture dated as
of August 17, 1998, as supplemented by the Seventh Supplemental Indenture, dated

"INDENTURE"), between the Company and The Bank of New York, as trustee (the

                                   DEFINITIONS

     The following terms, as used herein, have the following meanings unless the
context or use clearly indicates another or different meaning or intent:

     "ADJUSTED TREASURY RATE" means, with respect to any redemption date:

     (i)  the yield, under the heading which represents the average for the
          immediately preceding week, appearing in the most recently published
          statistical release designated "H.15(519)" or any successor
          publication which is published weekly by the Board of Governors of the
          Federal Reserve System and which establishes yields on actively traded
          United States Treasury securities adjusted to constant maturity under
          the caption "Treasury Constant Maturities," for the maturity
          corresponding to the Comparable Treasury Issue (if no maturity is
          within three months before or after the Remaining Life, as defined
          below, yields for the two published maturities most closely
          corresponding to the Comparable Treasury Issue will be determined and
          the Adjusted Treasury Rate will be interpolated or extrapolated from
          such yields on a straight line basis, rounding to the nearest month);
          or

     (ii) if such release (or any successor release) is not published during the
          week preceding the calculation date or does not contain such yields,
          the rate per annum equal to the semi-annual equivalent yield to
          maturity of the Comparable Treasury Issue, calculated using 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.

The Adjusted Treasury Rate will be calculated on the third Business Day
preceding the redemption date.

     "BUSINESS DAY" shall mean any day other than a Saturday or Sunday that is
neither a legal holiday nor a day on which banking institutions are authorized
or required by law or regulations to close in the City of New York.

     "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 Notes to be redeemed that would be used, 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 such Notes (the "REMAINING LIFE").

     "COMPARABLE TREASURY PRICE" means (1) the average of five Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest Reference Treasury Dealer Quotations, or (2) if an Independent
Investment Banker obtains fewer than five such Reference Treasury Dealer
Quotations, the average of all such quotations.

depositary.

is paid, which date(s) are set forth on the face of this Note.

     (i)  Banc of America Securities LLC, BNY Capital Markets, Inc., Credit
          Suisse First Boston Corporation, Salomon Smith Barney Inc. and each of
          their respective successors; provided that, if any such Reference
          Treasury Dealer ceases to be a primary U.S. Government securities
          dealer in New York City ("Primary Treasury Dealer"), the Company will
          substitute another Primary Treasury Dealer; and

     (ii) one other Primary Treasury Dealer selected by the Company.

     "REFERENCE TREASURY DEALER QUOTATIONS" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
an Independent Investment Banker, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to an Independent Investment Banker at 5:00 p.m., New York
City time, on the third Business Day preceding such redemption date.

                                  INTEREST RATE

     This Note will bear interest at the rate per annum (computed based on a
360-day year consisting of twelve 30-day months) identified on the face of this
Note.

                               OPTIONAL REDEMPTION

     The Notes are subject to redemption, in whole or in part, at any time, and
at the option of the Company, at a redemption price equal to the greater of:

          principal and interest on the Notes then outstanding to be redeemed
          (not including any portion of such payments of interest accrued as of
          the redemption date) discounted to the redemption date on a semiannual
          basis (computed based on a 360-day year consisting of twelve 30-day
          months) at the Adjusted Treasury Rate, plus 25 basis points (0.25%),
          as calculated by an Independent Investment Banker,

plus, in both of the above cases, accrued and unpaid interest thereon to the
redemption date.

     The Company will mail a notice of redemption at least 30 days but no more
than 60 days before the redemption date to each holder of Notes to be redeemed.
If the Company elects to partially redeem the Notes, the Trustee will select in
a fair and appropriate manner the Notes to be redeemed.

     Unless the Company defaults in payment of the redemption price, on and
after the redemption date, interest will cease to accrue on the Notes or
portions thereof called for redemption.

     The Notes are not entitled to the benefit of any sinking fund or analogous
provision.
