     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

preceding the redemption date.

     "BUSINESS DAY" shall mean any day other than a Saturday or Sunday that is

     "COMPARABLE TREASURY ISSUE" means the United States Treasury security

with respect to the 2007 Notes, the remaining term of the 2007 Notes to be
redeemed, and, with respect to the 2012 Notes, the remaining term of the 2012
Notes to be redeemed, that would be used, at the time of

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" shall mean The Depository Trust Company or any successor
depositary.

     "INDEPENDENT INVESTMENT BANKER" means any of Salomon Smith Barney Inc.,
Barclays Capital Inc. and J.P. Morgan Securities Inc., or any of their
respective successors, as designated by the Company, or if those 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 August 15 and February 15 of each year.

initially issued by the Company, such date to be set forth on the face of each

Original Indenture.

     "REFERENCE TREASURY DEALER" means:

          (i) Salomon Smith Barney Inc., Barclays Capital Inc. and J.P. Morgan
     Securities 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 (a "PRIMARY TREASURY DEALER"), the
     Company will substitute another Primary Treasury Dealer; and

          (ii) up to two other Primary Treasury Dealers 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)

City time, on the third Business Day preceding such redemption date.

be postponed to the next succeeding Business Day, and no interest will accrue on
such payment for the period from and after such Interest Payment Date to the

                                  ARTICLE FOUR

           APPROVAL OF AMENDMENT TO SECTION 801 OF ORIGINAL INDENTURE

                                  ARTICLE FIVE

                  PAYMENTS IN THE EVENT OF CERTAIN TRANSACTIONS

     In the event that the payment of the principal of and interest on the Notes
has been expressly assumed pursuant to Section 801(1) of the Original Indenture,
as amended by the Third Supplemental Indenture, by a Corporation or Person
organized and existing under the laws of a foreign jurisdiction (a "FOREIGN
SUCCESSOR") and such Foreign Successor is required to withhold any taxes, duties
or other governmental charges with respect to such principal or interest
payments (collectively, a "FOREIGN WITHHOLDING TAX") imposed or levied by such
foreign jurisdiction or a political subdivision thereof, then such Foreign
Successor shall pay such additional amounts ("ADDITIONAL AMOUNTS") included in
the interest or principal otherwise then due and payable as are necessary so
that the net amount received by each Holder of the Notes after the withholding
of any Foreign Withholding Tax (including any Foreign Withholding Tax imposed
with respect to such Additional Amounts) will not be less than the amount of
interest or principal then otherwise due and payable. However, the Foreign
Successor shall not be required to pay any Additional Amounts to the extent that
(i) a Foreign Withholding Tax is imposed or levied because of a present or
former connection between the Holder of the Notes (or the beneficial owner of
such securities) and the foreign jurisdiction, other than a connection arising
solely from the Holder (or beneficial owner) having received a payment of
principal of or interest on the Notes, or (ii) to the extent that the Foreign
Withholding Tax is imposed or levied because the Holder (or beneficial owner)
has not made a declaration of non-residence in, or other lack of connection
with, the foreign jurisdiction or any similar claim for exemption from, or
reduction of, withholding tax, provided that the Foreign Successor or its agent
notifies the Holder of the Notes of the requirement for such a declaration or
claim in a reasonable and timely manner.

     TAMPA ELECTRIC COMPANY, a corporation duly organized and existing under the
laws of the State of Florida (herein called the "COMPANY," which term includes
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to CEDE & CO., or registered assigns, the
principal sum set forth on the face of this Note on the Stated Maturity, upon
the presentation and surrender hereof at the principal corporate trust office of
The Bank of New York, or its successor in trust (the "TRUSTEE") or such other
office as the Trustee has designated in writing, and to pay interest on the
unpaid principal balance hereof at a rate per annum (computed based on a 360-day
year consisting of twelve 30-day months) equal to the Interest Rate set forth on
the face of this Note for the period from the Original Issue Date to, but
excluding, the Stated Maturity.

     Interest will be payable on the Interest Payment Dates to the Person in
whose name this Note is registered at the close of business on the related
Record Date, which is the fifteenth calendar day (whether or not a Business Day)
immediately preceding the related Interest Payment Date. In each case, payments
shall be made in accordance with the provisions hereof, until the principal
hereof is paid or duly made available for payment.

     Interest on this Note will be computed on the basis of a year of 360 days
consisting of twelve 30-day months. Except for the effect of any adjustment in
the Interest Payment Date as provided in the following sentence, the amount of
interest payable for any period shorter than a full six-month period for which
interest is computed, will be computed on the basis of the actual number of days
elapsed in such a 180-day period. If any Interest Payment Date would otherwise
be a day that is not a Business Day, the payment required to be made on such
Interest Payment Date will be postponed to the next succeeding Business Day, and
no interest will accrue on such payment for the period from and after such
Interest Payment Date to the date of such payment on the next succeeding
Business Day, except that, if such Business Day is in the next succeeding
calendar year, 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 date.

     Payment of the principal of (and premium, if any) and any such interest on
this Note shall be made in immediately available funds at the office or agency
of the Company maintained for that purpose in the City of New York in 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.

     Reference is hereby made to the further provisions of this Note 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 Note shall
not be entitled to any benefit under the Indenture or be valid or obligatory for
any purpose.

     This Note is one of a duly authorized series of securities of the Company
(herein called the "NOTES"), issued and to be issued under an Indenture dated as
of July 1, 1998, as supplemented by the Fourth Supplemental Indenture, dated as
of August 15, 2002 (as such has been or shall be amended or supplemented, the
"INDENTURE"), between the Company and The Bank of New York, as trustee (the
"TRUSTEE", which term includes any successor Trustee under the Indenture), to
which Indenture reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Notes and of the terms upon which the Notes
are, and are to be, authenticated and delivered. This Note is one of the
securities of the series designated on the face hereof.

                                   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 obligated by law or executive order to close in the City of New York.

                                       3

<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 the 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" shall mean The Depository Trust Company or any successor
depositary.

     "INDEPENDENT INVESTMENT BANKER" means any of Salomon Smith Barney Inc.,
Barclays Capital Inc. and J.P. Morgan Securities Inc. or any of their respective
successors, as designated by the Company, or if those 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 August 15 and February 15 of each year.

     "REFERENCE TREASURY DEALER" means:

     (i)  Salomon Smith Barney Inc., Barclays Capital Inc. and J.P. Morgan
          Securities 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 (a "PRIMARY
          TREASURY DEALER"), the Company will substitute another Primary
          Treasury Dealer; and

     (ii) up to two other Primary Treasury Dealers 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. Except for the effect of any adjustment in the Interest Payment Date as
provided in the following sentence, the amount of interest payable for any
period shorter than a full six-month period for which interest is computed, will
be computed on the basis of the actual number of days elapsed in such a 180-day
period. If any Interest Payment Date would otherwise be a day that is not a
Business Day, the payment required to be made on such Interest Payment Date will
be postponed to the next succeeding Business Day, and no interest will accrue on
such payment for the period from and after such Interest Payment Date to the
date of such payment on the next succeeding Business Day, except that, if such
Business Day is in the next succeeding calendar year, such payment

                                       4

<PAGE>

shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on such date.

                               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:

     (i)  100% of the principal amount of the 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 ____ basis points (____%),
          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 the 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.

                              TRANSFER OR EXCHANGE

     As provided in the Indenture and subject to certain limitations herein and
therein set forth, the transfer of this Note is registerable in the Security

or agency of the Company in any place where the principal of (and premium, if
any) and interest on this Note are payable, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Notes of this series and of
like tenor, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

     The Notes are issuable only in registered form without coupons and, except
for such Notes issued in book-entry form, only in denominations of $1,000 and
any integral multiple of $1,000. As provided in the Indenture and subject to
certain limitations herein and therein set forth, this Note is exchangeable for

<PAGE>

of like tenor of a different authorized denomination, 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.

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

                                OTHER PROVISIONS

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the

consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected and of the Holders of 66 2/3%
in principal amount of the Securities at the time Outstanding of all series to
be affected. 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. To the extent
permitted by law, any such consent or waiver by the Holder of this Note shall be
conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange
hereof or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Note.

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

     All terms used in this Note which are defined in the Indenture shall have
the meanings assigned to them in the Indenture.

     TAMPA ELECTRIC COMPANY, a corporation duly organized and existing under the
laws of the State of Florida (herein called the "COMPANY," which term includes
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to CEDE & CO., or registered assigns, the
principal sum set forth on the face of this Note on the Stated Maturity, upon
the presentation and surrender hereof at the principal corporate trust office of
The Bank of New York, or its successor in trust (the "TRUSTEE") or such other
office as the Trustee has designated in writing, and to pay interest on the
unpaid principal balance hereof at a rate per annum (computed based on a 360-day
year consisting of twelve 30-day months) equal to the Interest Rate set forth on
the face of this Note for the period from the Original Issue Date to, but
excluding, the Stated Maturity.

     Interest will be payable on the Interest Payment Dates to the Person in
whose name this Note is registered at the close of business on the related
Record Date, which is the fifteenth calendar day (whether or not a Business Day)
immediately preceding the related Interest Payment Date. In each case, payments
shall be made in accordance with the provisions hereof, until the principal
hereof is paid or duly made available for payment.

     Interest on this Note will be computed on the basis of a year of 360 days
consisting of twelve 30-day months. Except for the effect of any adjustment in
the Interest Payment Date as provided in the following sentence, the amount of
interest payable for any period shorter than a full six-month period for which
interest is computed, will be computed on the basis of the actual number of days
elapsed in such a 180-day period. If any Interest Payment Date would otherwise
be a day that is not a Business Day, the payment required to be made on such
Interest Payment Date will be postponed to the next succeeding Business Day, and
no interest will accrue on such payment for the period from and after such
Interest Payment Date to the date of such payment on the next succeeding
Business Day, except that, if such Business Day is in the next succeeding
calendar year, 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 date.

     Payment of the principal of (and premium, if any) and any such interest on
this Note shall be made in immediately available funds at the office or agency
of the Company maintained for that purpose in the City of New York in 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.

     Reference is hereby made to the further provisions of this Note 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 Note shall
not be entitled to any benefit under the Indenture or be valid or obligatory for
any purpose.

     This Note is one of a duly authorized series of securities of the Company
(herein called the "NOTES"), issued and to be issued under an Indenture dated as
of July 1, 1998, as supplemented by the Fourth Supplemental Indenture, dated as
of August 15, 2002 (as such has been or shall be amended or supplemented, the
"INDENTURE"), between the Company and The Bank of New York, as trustee (the
"TRUSTEE", which term includes any successor Trustee under the Indenture), to
which Indenture reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Notes and of the terms upon which the Notes
are, and are to be, authenticated and delivered. This Note is one of the
securities of the series designated on the face hereof.

                                   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 obligated by law or executive order to close in the City of New York.

                                       3

<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 the 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" shall mean The Depository Trust Company or any successor
depositary.

     "INDEPENDENT INVESTMENT BANKER" means any of Salomon Smith Barney Inc.,
Barclays Capital Inc. and J.P. Morgan Securities Inc. or any of their respective
successors, as designated by the Company, or if those 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 August 15 and February 15 of each year.

     "REFERENCE TREASURY DEALER" means:

     (i)  Salomon Smith Barney Inc., Barclays Capital Inc. and J.P. Morgan
          Securities 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 (a "PRIMARY
          TREASURY DEALER"), the Company will substitute another Primary
          Treasury Dealer; and

     (ii) up to two other Primary Treasury Dealers 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. Except for the effect of any adjustment in the Interest Payment Date as
provided in the following sentence, the amount of interest payable for any
period shorter than a full six-month period for which interest is computed, will
be computed on the basis of the actual number of days elapsed in such a 180-day
period. If any Interest Payment Date would otherwise be a day that is not a
Business Day, the payment required to be made on such Interest Payment Date will
be postponed to the next succeeding Business Day, and no interest will accrue on
such payment for the period from and after such Interest Payment Date to the
date of such payment on the next succeeding Business Day, except that, if such
Business Day is in the next succeeding calendar year, such payment

                                       4

<PAGE>

shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on such date.

                               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:

     (i)  100% of the principal amount of the 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 the 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.

                              TRANSFER OR EXCHANGE

     As provided in the Indenture and subject to certain limitations herein and
therein set forth, the transfer of this Note is registerable in the Security

Security Registrar duly executed by, the Holder hereof or his attorney duly

like tenor, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

     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.

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. To the extent
permitted by law, any such consent or waiver by the Holder of this Note shall be
conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange
hereof or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
