                  (b) Interest on the Senior Notes through the Initial Reset

                  (c) The rate of interest payable from time to time through the

Period (the "Rate of Interest") will be determined on the basis of the following
provisions:

                  (i) on the first day of such Interest Accrual Period (the
         "Interest Determination Date"), the Agent Bank will determine the
         Screen Rate at or about 11:00 a.m. (London time) on the Interest
         Determination Date. If such Screen Rate is unavailable, the Agent Bank
         will request the principal London office of each of the Reference Banks
         to provide the Agent Bank with its offered quotation to leading banks
         for Sterling deposits in the London interbank market for such Interest
         Accrual Period at or about 11:00 a.m. (London time) on the Interest
         Determination Date. The Rate of Interest for such Interest Accrual
         Period shall be such Screen Rate plus 0.805% per annum (the "Margin")
         or, if such Screen Rate is unavailable, the arithmetic average (rounded
         upwards if necessary to the nearest 1/16th of 1%) of the offered
         quotations provided by the Reference Banks (excluding the highest and
         lowest (or, in either case, if more than one, then only one of them) of
         such quotations) plus the Margin;

                  (ii) if on the Interest Determination Date such Screen Rate is
         unavailable and only four of the Reference Banks provide offered
         quotations, the Rate of Interest for such Interest Accrual Period shall
         be determined in accordance with the provisions of paragraph (i) above
         on the basis of the offered quotations of those Reference Banks
         providing the offered quotations (excluding the highest and lowest of
         such quotations as provided in paragraph (i) above);

                  (iii) if on the Interest Determination Date such Screen Rate
         is unavailable and only two or three of the Reference Banks provide
         offered quotations, the Rate of Interest for such Interest Accrual
         Period shall be determined in. accordance with the provisions of
         paragraph (i) above on the basis of the offered quotations of those
         Reference Banks providing the offered quotations (but without excluding
         the highest and lowest of such quotations as provided in paragraph (i)
         above); and

                  (iv) if on the Interest Determination Date such Screen Rate is
         unavailable and only one or none of the Reference Banks provides an
         offered quotation, then the Rate of Interest for such Interest Accrual
         Period shall be (a) the Rate of Interest in effect for that Interest
         Accrual Period to which paragraph (i), (ii) or (iii) above shall have
         applied which last preceded such Interest Accrual Period or (b) if
         determinable and if higher, the Reserve Interest Rate (as defined
         below). The "Reserve Interest Rate" shall be the rate per annum which
         the Agent Bank determines to be either (A) the arithmetic average
         (rounded upward if necessary to the nearest 1/16th of 1%) of the
         Sterling lending rates for loans in an amount approximately equal to
         the principal amount of the Senior Notes which London banks selected by
         the Agent Bank are quoting, at or about 11:00 a.m. (London time) on the
         Interest Determination Date, for such Interest Accrual Period, to the
         Reference Banks or those of them (being at least two in number) to
         which the quotations are, in the opinion of the Agent Bank, being so
         made plus the Margin or (B) if the Agent Bank cannot determine the
         arithmetic average, the lowest Sterling lending rate which four London
         banks selected by the Agent Bank are quoting, on the Interest
         Determination Date, for such Interest Accrual Period, to leading
         European banks plus the Margin.

                                      -6-




                  (d) The Agent Bank shall, as soon as practicable after 11:00
a.m. (London time) on each Interest Determination Date, but in no event later
than the third Business Day thereafter, determine the Sterling amount payable in
respect of interest on the principal amount of the Senior Notes (the "Interest
Amount") for the relevant Interest Accrual Period. The Interest Amount for any
Interest Accrual Period shall be determined by (i) applying the Rate of Interest
for such Interest Accrual Period to the principal amount of the Senior Notes and
(ii) multiplying that amount by the actual number of days in such Interest
Accrual Period divided by 365 (or if such Interest Accrual Period ends after
February 28 in a leap year, 366) expressed as a decimal and rounded upward if
necessary to the nearest 1/16th of 1%.

                  (e) All determinations, certificates, calculations, quotations
and decisions given, expressed, made or obtained for the purposes of the pro-
visions of this Section 202, whether by the Reference Banks (or any of them) or
the Agent Bank, will (in the absence of willful default, bad faith or manifest
error) be binding on the Company, the Guarantor, the Reference Banks, the Agent
Bank, the Paying Agent and all holders of Senior Notes, and (in the absence as
referred to above) no liability to the Company, the Guarantor or the holders of
Senior Notes shall attach to the Reference Banks or the Agent Bank in
connection with the exercise or non-exercise by them of their powers, duties and
discretions under this Section 202.

                  SECTION 203.      Conversion Event.

                  (a) Upon the occurrence of a Conversion Event, then
automatically (i) the aggregate principal amount of the Senior Notes shall
convert to $250,000,000 effective from the date of the immediately preceding
Interest Payment Date prior to the occurrence of such Conversion Event, (ii) the
interest rate on the Senior Notes shall convert to 8.25% per annum effective
from the date of the immediately preceding Interest Payment Date prior to the
occurrence of such Conversion Event and (iii) such interest rate shall be
calculated on the basis of a 360-day year of twelve 30-day months.

                  (b) Notwithstanding anything in Section 502 of the Original
Indenture to the contrary, the aggregate principal amount of the Outstanding
Senior Notes that shall become immediately due and payable upon a Conversion
Event shall be as set forth in clause (i) of Section 203(a) hereof.

                  (c) Upon a Conversion Event, the Trustee shall provide notice
by first class mail within 15 calendar days after the occurrence of such
Conversion Event (or if the declaration of acceleration relating to such
Conversion Event shall have been given by holders of the Senior Notes, after the
date on which the Trustee shall receive notice of such acceleration) of the
information set forth in this Section 203 to any securities exchange on which
the Senior Notes may then be listed and to the holder of the Senior Notes.

                  SECTION 204.      Interest after Initial Reset Date.

                  (a) Interest Rate to Maturity.

                  (i) In accordance with the procedures established in the
Remarketing Agreement and subject to Section 212, the interest rate in effect
with respect to the Senior Notes immediately prior to the Initial Reset Date
shall be reset on the Initial Reset Date to equal the Interest Rate to Maturity,


                                      -7-


which shall be effective from and including the Initial Reset Date to but
excluding the final maturity of the Senior Notes, unless the Company shall
exercise the Floating Rate Option in accordance with paragraph (b) of this
Section 204. If the Company shall have so exercised the Floating Rate Option,
then the Floating Period Interest Rate shall be reset in accordance with the
Remarketing Agreement on the Reset Date corresponding to the Floating Rate
Period Termination Date to equal the Interest Rate to Maturity, which shall be
effective from and including such Reset Date to but excluding the final maturity
of the Senior Notes.

                  (ii) During the period from and including the Fixed Rate Reset
Date to but excluding the final maturity of the Senior Notes, interest on the
Senior Notes shall accrue on the principal amount of the Senior Notes at the
Interest Rate to Maturity and shall be payable semi-annually on each Interest
Payment Date, commencing with the first such Interest Payment Date following the
Fixed Rate Reset Date; provided, however, that, if any such 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 any such delay). Interest on the Senior
Notes from the Fixed Rate Reset Date shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.

                  (b) Floating Rate Period.

                  (i) In accordance with procedures established in the
Remarketing Agreement and subject to Section 212, if the Company exercises the
Floating Rate Option no later than the seventh Business Day prior to the
Floating Rate Spread Determination Date by providing notice to the Trustee and
Remarketing Agent, then the Senior Notes shall bear interest at the Floating
Period Interest Rate for each Floating Rate Reset Period in the Floating Rate
Period.

                  (ii) During each Floating Rate Reset Period in the Floating
Rate Period, interest on the Senior Notes shall accrue on the Floating Rate
Purchase Price at the Floating Period Interest Rate for such Floating Rate Reset
Period and shall be payable quarterly on each Interest Payment Date, commencing
with the first such Interest Payment Date following the Initial Reset Date. The
Interest Amount for such Floating Rate Reset Period shall be determined by (A)
applying the Floating Period Interest Rate for such Floating Rate Reset Period
to the Floating Rate Purchase Price and (B) multiplying that amount by the
actual number of days in such Floating Rate Reset Period divided by 365 (or, if
such Floating Rate Reset Period ends after February 28 in a leap year, 366)
expressed as a decimal and rounded upward if necessary to the nearest 1/16th of
1%.

                  (c) Notice.

                  Subject to Section 212, the Remarketing Agent shall notify the

Reset Date, if the Company elects the Floating Rate Option, of the Floating
Period Interest Rate for the Floating Rate Reset Period beginning on such Reset

            decreases and increases in the aggregate principal amount of
            Securities evidenced by this certificate and (ii) the other
            provisions of this Security providing for the conversion to a US
            Dollar-denominated Security.

                                      A-2



                 The per annum interest rate on the Securities for each
Interest Accrual Period through the Initial Reset Date will be reset
semi-annually based on procedures set forth below and established in the
Indenture; provided, however, that upon the occurrence of a Conversion Event,
this Security will convert to a US Dollar-denominated Security as provided in
the Indenture.

                  The rate of interest payable from time to time through the
Initial Reset Date in respect of this Security, for any Interest Accrual Period
(the "Rate of Interest") will be determined on the basis of the following
provisions:

                  (i) on the first day of such Interest Accrual Period (the
         "Interest Determination Date"), the Agent Bank will determine the
         Screen Rate for six-month Sterling deposits at or about 11:00 a.m.
         (London time) on the Interest Determination Date. If such Screen Rate
         is unavailable, the Agent Bank will request the principal London office
         of each of the Reference Banks to provide the Agent Bank with its
         offered quotation to leading banks for Sterling deposits in the London
         interbank market for such Interest Accrual Period at or about 11:00
         a.m. (London time) on the Interest Determination Date. The Rate of
         Interest for such Interest Accrual Period shall be such Screen Rate
         plus 0.805% per annum (the "Margin") or, if such Screen Rate is
         unavailable, the arithmetic average (rounded upwards if necessary to
         the nearest 1/16th of 1%) of the offered quotations provided by the
         Reference Banks (excluding the highest and lowest (or, in either case,
         if more than one, then only one of them) of such quotations) plus the
         Margin;

                  (ii) if on the Interest Determination Date such Screen Rate is
         unavailable and only four of the Reference Banks provide offered
         quotations, the Rate of Interest for such Interest Accrual Period shall
         be determined in accordance with the provisions of paragraph (i) above
         on the basis of the offered quotations of those Reference Banks
         providing the offered quotations (excluding the highest and lowest of
         such quotations as provided in paragraph (i) above);

                  (iii) if on the Interest Determination Date such Screen Rate
         is unavailable and only two or three of the Reference Banks provide
         offered quotations, the Rate of Interest for such Interest Accrual
         Period shall be determined in accordance with the provisions of
         paragraph (i) above on the basis of the offered quotations of those
         Reference Banks providing the offered quotations (but without excluding
         the highest and lowest of such quotations as provided in paragraph (i)
         above); and

                  (iv) if on the Interest Determination Date such Screen Rate is
         unavailable and only one or none of the Reference Banks provides an
         offered quotation, then the Rate of Interest for such Interest Accrual
         Period shall be (a) the Rate of Interest in effect for that Interest
         Accrual Period to which paragraph (i), (ii) or (iii) above shall have
         applied which last preceded such Interest Accrual Period or (b) if
         determinable and if higher, the Reserve Interest Rate (as defined
         below). The "Reserve Interest Rate" shall be the rate per annum which
         the Agent Bank determines to be either (A) the arithmetic average
         (rounded upward if necessary to the nearest 1/16th of 1%) of the
         Sterling lending rates for loans in an amount approximately equal to
         the principal amount of the Securities which London banks selected by
         the Agent Bank are quoting, at or about 11:00 a.m. (London time) on the
         Interest Determination Date, for such Interest Accrual Period, to the

                                      A-3



         Reference Banks or those of them (being at least two in number) to
         which the quotations] are, in the opinion of the Agent Bank, being so
         made plus the Margin or (B) if the Agent Bank cannot determine the
         arithmetic average, the lowest Sterling lending rate which four London
         banks selected by the Agent Bank are quoting, on the Interest
         Determination Date, for such Interest Accrual Period, to leading
         European banks plus the Margin.

                  The Interest Amount shall be determined by (i) applying the
Rate of Interest for such Interest Accrual Period to the principal amount of the
Securities and (ii) multiplying that amount by the actual number of days in such
Interest Accrual Period divided by 365 (or if such Interest Accrual Period ends
after February 28 in a leap year, 366) expressed as a decimal and rounded upward
if necessary to the nearest 1/16th of 1%.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, relating to the interest reset and
remarketing mechanics of this Security after the Initial Reset Date.

                  All payments in respect of this Security and all payments made
pursuant to the Guarantee of this Security shall be made in immediately
available funds at or through the office or agency of the Company maintained for
that purpose in the Borough of Manhattan, The City of New York, and for so long
as this Security shall be listed on the Luxembourg Stock Exchange, in
Luxembourg, in such coin or currency of the United Kingdom or the United States
of America, as the case may be, as at the time of payment is legal tender for
the payment of public and private debt. The Trustee shall make
Sterling-denominated payments on the Senior Notes through a London-based account
of the Trustee.

                  All payments of principal of, and premium, if any, and
interest in respect of this Security and all payments made pursuant to the
Guarantee of this Security shall be made free and clear of, and without
withholding or deduction for or on account of any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed, levied,
collected, withheld or assessed by or within a Taxing Jurisdiction or by or
within any political subdivision thereof or any authority therein or thereof
having power to tax ("Gross-Up Taxes"), unless such withholding or deduction is
required by law. In the event of any such withholding or deduction, the Company
or the Guarantor, as the case may be, shall pay to the Holder such additional
amounts in respect of such withholding or reduction as are necessary so that the
Holder receives the amount that would have been due in the absence of such
withholding or deduction ("Additional Amounts"), except that no such Additional
Amounts shall be payable:

                  (a) to, or to a Person on behalf of, a Holder who is Liable
         for such Gross-Up Taxes in respect of this Security or the Guarantee of
         this Security by reason of such Holder or beneficial owner having some
         connection with the relevant Taxing Jurisdiction (including being a
         citizen or resident or national of, or carrying on a business or
         maintaining a permanent establishment in, or being physically present
         in, such Taxing Jurisdiction) other than the mere holding of this
         Security or the receipt of principal of, and premium, if any, and
         interest in respect thereon or in respect of the Guarantee of this
         Security;

                                      A-4



                  (b) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) for payment more than 30
         days after the Relevant Date except to the extent that the Holder would
         have been entitled to such Additional Amounts on presenting this
         Security for payment on the last day of such period of 30 days;

                  (c) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) in a Taxing Jurisdiction
         or, so long as the Senior Notes are listed on the Luxembourg Stock
         Exchange, in Luxembourg;

                  (d) to, or to a Person on behalf of, a Holder who would not be
         liable or subject to the withholding or deduction by making a
         declaration of nonresidence or similar claim for exemption to the
         relevant Taxing Jurisdiction; or

                  (e) to, or to a Person on behalf of, a Holder of a Registered
         Security that is not a Global Security issued pursuant to the request
         of any beneficial owner of an interest in the Security (an "Optional
         Definitive Security Request") following and during the continuance of
         an Event of Default if such Holder (or any predecessor Holder) was an
         owner requesting that such Registered Securities be so issued.

                  Such Additional Amounts will also not be payable where, had
the beneficial owner of the Security (or any interest therein) been the Holder
of the Security, such owner would not have been entitled to payment of
Additional Amounts by reason of any one or more of clauses (a) through (e)
above. If the Company or the Guarantor, as applicable, shall determine that
Additional Amounts will not be payable because of the immediately preceding
sentence, the Company or the Guarantor, as applicable, will inform such Holder
promptly after making such determination setting forth the reason(s) therefor.

                  "Relevant Date" means, in respect of any payment, whichever is
the later of (i) the date on which such payment first becomes due and (ii) if
the full amount payable has not been received in The City of New York by the
Book-Entry Depositary or the Trustee on or prior to such due date, the date on
which, the full amount having been so received, notice to that effect shall have
been given to the bearer hereof in accordance with the Indenture.

                  References to principal of, and premium or interest in respect
of, this Security or any payments pursuant to the Guarantee of this Security
shall be deemed to include any Additional Amounts which may be payable as set
forth in the Indenture or in this Security.

                  The Company shall furnish to the Trustee the official receipts
(or a certified copy of the official receipts) evidencing payment of the
Gross-Up Taxes. Copies of such receipts shall be made available to the Holder of
this Security upon request.

                  All notices regarding the Securities of this Series shall be
published in a leading English language daily newspaper of general circulation
in London. Furthermore, so long as the Securities of this series are listed on
the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange so
require, notices to Holders of Securities of this series will also be published
in a leading newspaper having general circulation in Luxembourg (which is
expected to be the Luxemburger Wort).

                                      A-5



                  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.


                                      A-6



                  IN WITNESS WHEREOF, the Company has caused this instrument to
be duly executed by an authorized signatory of the Company.

                          [Form of Reverse of Security]

                        YORKSHIRE POWER FINANCE 2 LIMITED
                    Reset Senior Notes Due February 15, 2020

                  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, dated as of February 1, 2000 (herein called
the "Original Indenture"), among the Company, Yorkshire Power Group Limited, as
guarantor (the "Guarantor"), and The Bank of New York, as trustee, principal
paying agent, registrar and transfer agent (herein called the "Trustee", which
term includes any successor trustee under the Indenture), as supplemented by the
First Supplemental Indenture, dated as of February 16, 2000 (the "First
Supplemental Indenture"; together with the Original Indenture and any other
supplements thereto, the "Indenture"), among the Company, the Guarantor and the
Trustee 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 Guarantor, 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 (pound)155,000,000; provided, however,
that upon a Conversion Event, such aggregate principal amount shall be limited
to $250,000,000.

                  Certain provisions with respect to the interest rate reset
procedures for the Securities after the Initial Reset Date set forth below are
contained in a Remarketing Agreement (the "Remarketing Agreement") between the
Company, the Guarantor and Warburg Dillon Read LLC, as Remarketing Agent (the
"Remarketing Agent").

                  In accordance with the procedures established in the
Remarketing Agreement and subject to Section 212 of the First Supplemental
Indenture, the interest rate in effect with respect to the Securities
immediately prior to the Initial Reset Date shall be reset on the Initial Reset
Date to equal the Interest Rate to Maturity which shall be effective from and
including the Initial Reset Date to but excluding the final maturity of the
Securities, unless the Company shall exercise the Floating Rate Option in
accordance with the provisions herein. If the Company shall have so exercised
the Floating Rate Option, then the Floating Period Interest Rate shall be reset
in accordance with the Remarketing Agreement on the Reset Date corresponding to
the Floating Rate Period Termination Date to equal the Interest Rate to
Maturity, which shall be effective from and including such Reset Date to but
excluding the final maturity of the Securities.

                  During the period from and including the Fixed Rate Reset Date
to but excluding the final maturity of the Securities, interest on the
Securities shall accrue on principal amount of the Securities at the Interest
Rate to Maturity and shall be payable semi-annually on each Interest Payment
Date, commencing with the first such Interest Payment Date following the Fixed
Rate Reset Date; provided, however, that, if any such 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 any such delay). Interest on the Securities from the
Fixed Rate Reset Date shall be computed on the basis of a 360-day year
consisting of twelve 30-day months.

                                      A-8



                  In accordance with procedures established in the Remarketing
Agreement and subject to Section 212 of the First Supplemental Indenture, if the
Company exercises the Floating Rate Option no later than the seventh Business
Day prior to the Floating Rate Spread Determination Date by providing notice to
the Trustee and Remarketing Agent, then the Securities shall bear interest at
the Floating Period Interest Rate for each Floating Rate Reset Period in the
Floating Rate Period.

                  During each Floating Rate Reset Period in the Floating Rate
Period, interest on the Securities shall accrue on the Floating Rate Purchase
Price at the Floating Period Interest Rate for such Floating Rate Reset Period
and shall be payable quarterly on each Interest Payment Date, commencing with
the first such Interest Payment Date following the Initial Reset Date. The
Interest Amount for such Floating Rate Reset Period shall be determined by (A)
applying the Floating Period Interest Rate for such Floating Rate Reset Period
to the Floating Rate Purchase Price and (B) multiplying that amount by the
actual number of days in such Floating Rate Reset Period divided by 365 (or, if
such Floating Rate Reset Period ends after February 28 in a leap year, 366)
expressed as a decimal and rounded upward if necessary to the nearest 1/16th of
1%.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Securities shall be automatically tendered, or deemed tendered,
by the Holders thereof to the Remarketing Agent for purchase on the Floating
Rate Period Termination Date. On the Reset Date corresponding to the Floating
Rate Period Termination Date, the interest rate on the Securities shall be reset
to equal the Interest Rate to Maturity in accordance with, and the Securities
shall be remarketed pursuant to, the Remarketing Agreement.

                  The purchase price for the Securities tendered pursuant to the
paragraph above shall equal 100% of the Floating Rate Purchase Price plus
accrued and unpaid interest, if any, thereon to but excluding the Floating Rate
Period Termination Date. If for any reason the Remarketing Agent does not
purchase all of the Securities on the Floating Rate Period Termination Date, the
Company shall redeem the Securities on the Floating Rate Period Termination Date
at a redemption price equal to 100% of the Floating Rate Purchase Price plus
accrued and unpaid interest, if any, thereon to but excluding the Floating Rate
Period Termination Date. If the Remarketing Agent elects to purchase the
Securities, such obligation of the Remarketing Agent is subject to the
conditions set forth in the Remarketing Agreement.

                  In the event that the Callholder (i) has not given notice on
or before January 10, 2005 of its intention to exercise the call option under
the Call Option Agreement or (ii) fails to pay on or before the Business Day
next preceding the Early Redemption Date the call price required under the Call
Option Agreement, the Company shall redeem on February 15, 2005 (such date,
unless it is not a Business Day, in which case the next succeeding day that is a
Business day, the "Early Redemption Date"), in whole but not in part, the
Securities at a redemption price equal to 100% of the aggregate principal amount
of the Securities plus accrued and unpaid interest thereon to but excluding the
Early Redemption Date, upon written notice by 5:00 p.m. London time on the
Business Day next preceding Early Redemption Date from the Book-Entry
Depository, as holder of the Securities.

                                      A-9



                  Any such written notice given by the Book-Entry Depository, as
holder of the Securities, shall be irrevocable; provided, however, that if prior
to the Early Redemption Date an Event of Default shall have occurred and be
continuing, such holder, at its option, may elect by written notice to the
Company, to withdraw such instruction and instead to declare the Securities to
be due and payable pursuant to Section 502 of the Original Indenture.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Company shall be required to redeem the Securities, in whole
but not in part, on any Reset Date following the Initial Reset Date at a
redemption price equal to the Floating Rate Purchase Price plus accrued and
unpaid interest, if any, thereon to but excluding such Reset Date in the event
that (i) the Remarketing Agent for any reason does not notify the Company of the
Floating Period Interest Rate for the Floating Rate Reset Period beginning on
such Reset Date by 4:00 p.m. (London time) on such Reset Date or of the Interest
Rate to Maturity by 4:00 p.m., (London time) on the Fixed Rate Determination
Date, as applicable, (ii) prior to any such Reset Date, the Remarketing Agent
resigns and no successor has been appointed on or before such Reset Date or
Determination date, as applicable, (iii) the Remarketing Agent elects to
terminate the Remarketing Agreement in accordance with its terms, (iv) the
Remarketing Agent for any reason does not elect (by notice to the Company and
the Trustee not later than the Fixed Rate Determination Date) to purchase the
Securities for remarketing on the Floating Rate Period Termination Date, (v) the
Remarketing Agent for any reason does not deliver the purchase price of the
Securities to or through DTC on or before the Floating Rate Period Termination
Date as provided in the Remarketing Agreement or (vi) the Company for any reason
fails to redeem the Securities following the Company's election to effect such
redemption as set forth in paragraph (c) of this Section 212.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Company shall notify the Callholder, the Remarketing Agent and
the Trustee, not later than the Business Day immediately preceding the Floating
Rate Period Termination Date, if the Company irrevocably elects to exercise its
right to redeem the Senior Notes, in whole but not in part, from the Remarketing
Agent on the Floating Rate Period Termination Date. If the Company elects to
redeem the Securities, the Company shall redeem the Securities in whole at a
redemption price equal to the Floating Rate Purchase Price plus accrued and
unpaid interest, if any, thereon to but excluding the Floating Rate Period
Termination Date.

                  The tender and settlement procedures set forth above,
including provisions for payment by purchasers of the Securities to any
remarketing agent or for payment of the Securities, may be modified to the
extent required by DTC or to the extent required to facilitate the tender and
remarketing of the Securities at the time of the remarketing. In addition, the
Remarketing Agent may, without the consent of holders of the Securities, modify
the tender and settlement procedures specified above in order to facilitate the
tender and settlement process.

                  Unless the Company defaults in payment of the redemption
price, from and after a redemption date, the Securities of this series or
portions thereof called for redemption will cease to bear interest, and the
Holders thereof will have no right in respect of such Securities of this series
except the right to receive the redemption price thereof.

                                      A-10



                  The Indenture contains provisions for defeasance of (a) the
entire indebtedness of the Securities and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

                  If an Event of Default with respect to the Securities shall
occur and be continuing, the principal of the Securities may be declared due and
payable in the manner and with the effect provided in the Indenture. At any time
after such declaration of acceleration with respect to the Securities has been
made, but before a judgment or decree for payment of money has been obtained by
the Trustee as provided in the Indenture, if all Events of Default with respect
to the Securities have been cured or waived (other than the non-payment of
principal of the Securities which has become due solely by reason of such
declaration of acceleration) then such declaration of acceleration and its
consequences shall be automatically annulled and rescinded.

                  This Security is subject to redemption in whole but not in
part upon not less than 30 nor more than 60 days' notice given as provided in
the Indenture, at a price equal to the outstanding principal amount thereof,
together with Additional Amounts, if any, and accrued interest, if any, to the
Redemption Date if, (a) the Company or the Guarantor satisfies the Trustee prior
to the giving of such notice that it has or will become obligated to pay
Additional Amounts as a result of either (i) any change in, or amendment to, the
laws or regulations of a Taxing Jurisdiction, or any change in the application
or interpretation of such laws or regulations, which change or amendment becomes
effective on or after February 16, 2000 (or, in the case of any jurisdiction
other than a Taxing Jurisdiction, any such change or amendment that becomes
effective on or after the date on which the Company or the Guarantor, as the
case may be, is merged into, or conveyed or transferred or leased its properties
and assets substantially as an entirety to, any Person that is organized under
the laws of, or is managed or controlled or has a place of business in, such
jurisdiction) or (ii) the issuance of Definitive Registered Securities pursuant
to any of clauses (a), (b) or (d) of the third following paragraph and (b) such
obligation cannot be avoided by the Company or the Guarantor taking reasonable
measures available to it, subject, as provided in the Indenture, to the delivery
by the Company or the Guarantor of an Officers' Certificate stating that such
obligation to pay Additional Amounts cannot be avoided by the Company or the
Guarantor taking reasonable measures available to it.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the Indenture or any
supplemental indenture or the rights and obligations of the Company and the
rights of the Holders of the Securities of all 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 aggregate principal amount of the Securities at the
time Outstanding of all series to be affected (voting as a class). 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.

                                      A-11



                  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
premium, if any, and interest in respect of this Security at the times, place
and rate, and in the coin or currency, herein prescribed.

                  This Security shall be exchangeable, in whole or, in the case
of clause (d) below, in part as provided in the Indenture, for Definitive
Registered Securities registered in the names of Persons other than the
Book-Entry Depositary with respect to such series or its nominee only as
provided in this paragraph. This Security shall be so exchangeable if (a) DTC
notifies the Company and the Book-Entry Depositary that it is unwilling or
unable to continue to hold the Book-Entry Interests or at any time ceases to be
a "clearing agency" registered as such under the Exchange Act and in either
case, a successor is not appointed by the Company within 120 days, (b) the
Book-Entry Depositary for the Securities of this series notifies the Company
that it is unwilling or unable to continue as Book-Entry Depositary with respect
to this Security and no successor is appointed within 120 days, (c) the Company
executes and delivers to the Trustee an Officers' Certificate providing that
this Security shall be so exchangeable, (d) the Company receives an Optional
Definitive Securities Request or (e) while this Security is subject to the
transfer restrictions set forth in the Restricted Securities Legend hereon, on
or after the Initial Reset Date the Book-Entry Interests cease to be eligible
for DTC services because this Security is neither (i) rated in one of the top
four categories by a nationally recognized statistical rating organization nor
(ii) included within a self-regulatory organization system approved by the
Commission for the reporting of quotations and trade information of securities
eligible for trade pursuant to Rule 144A, such as the PORTAL system. Securities
so issued in exchange for this Security shall be of the same series, having the
same interest rate, if any, and maturity and having the same terms as this
Security, in authorized denominations and in the aggregate having the same
principal amount as this security and registered in such names as the Book-Entry
Depositary for this Security shall direct.

                  The bearer of this Security shall be treated as the owner of
it for all purposes, subject to the terms of the Indenture. 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 of a different authorized denomination, as
requested by the Holder surrendering the same.

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

                  When a successor assumes all the obligations of its
predecessor under the Securities of this series and the Indenture in accordance
with the terms of the Indenture, the predecessor will be released from those
obligations.

                  The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Securities of this series and
may otherwise deal with the Company, the Guarantor or their respective
Affiliates as if it were not the Trustee.

                                      A-12



                  No stockholder, director, officer, employee, incorporator or
Affiliate of the Company or the Guarantor shall have any liability for any
obligation of the Company or the Guarantor under the Securities of this series
or the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of the Securities of this series by
accepting Securities of this series waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the
Securities of this series.

                  YORKSHIRE POWER FINANCE 2 LIMITED, a limited liability company
incorporated under the laws of the Cayman Islands (herein called the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to [name of registered
owner], or its registered assigns, the principal sum of ONE HUNDRED FIFTY FIVE
MILLION POUNDS STERLING on February 15, 2020, and to pay interest thereon at the
rate or rates per annum described herein from February 16, 2000, or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semi-annually on February 15 and August 15 in each year,
commencing August 15, 2000, to the Initial Reset Date and thereafter subject to
the terms and conditions set forth herein, at the interest rate or rates
determined by the Remarketing Agent in accordance with the procedures set forth
on the reverse hereof, until the principal hereof is paid or made available for
payment. 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 fifteenth day (whether or not a Business Day)
immediately preceding such Interest Payment Date. Any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered on such Regular Record Date and may 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 said Indenture.
- -----------------------------------

      *Reference is made to (i) Schedule A attached hereto with respect to
      decreases and increases in the aggregate principal amount of Securities
      evidenced by this certificate and (ii) the other provisions of this
      Security providing for the conversion to a US Dollar denominated Security.


                                      B-1


                  The per annum interest rate on the Securities for each
Interest Accrual Period through the Initial Reset Date will be reset
semi-annually based on procedures set forth below and established in the
Indenture; provided, however, that upon the occurrence of a Conversion Event,
this Security will convert to a US Dollar denominated Security as provided in
the Indenture.

                  The rate of interest payable from time to time through the
Initial Reset Date in respect of this Security for any Interest Accrual Period
(the "Rate of Interest") will be determined on the basis of the following
provisions:

                  (i) on the first day of such Interest Accrual Period (the
         "Interest Determination Date"), the Agent Bank will determine the
         Screen Rate for six-month Sterling deposits at or about 11:00 a.m.
         (London time) on the Interest Determination Date. If such Screen Rate
         is unavailable, the Agent Bank will request the principal London office
         of each of the Reference Banks to provide the Agent Bank with its
         offered quotation to leading banks for Sterling deposits in the London
         interbank market for such Interest Accrual Period at or about 11:00
         a.m. (London time) on the Interest Determination Date. The Rate of
         Interest for such Interest Accrual Period shall be such Screen Rate
         plus 0.805% per annum (the "Margin") or, if such Screen Rate is
         unavailable, the arithmetic average (rounded upwards if necessary to
         the nearest 1/16th of 1%) of the offered quotations provided by the
         Reference Banks (excluding the highest and lowest (or, in either case,
         if more than one, then only one of them) of such quotations) plus the
         Margin;

                  (ii) if on the Interest Determination Date such Screen Rate is
         unavailable and only four of the Reference Banks provide offered
         quotations, the Rate of Interest for such Interest Accrual Period shall
         be determined in accordance with the provisions of paragraph (i) above
         on the basis of the offered quotations of those Reference Banks
         providing the offered quotations (excluding the highest and lowest of
         such quotations as provided in paragraph (i) above);

                  (iii) if on the Interest Determination Date such Screen Rate
         is unavailable and only two or three of the Reference Banks provide
         offered quotations, the Rate of Interest for such Interest Accrual
         Period shall be determined in accordance with the provisions of
         paragraph (i) above on the basis of the offered quotations of those
         Reference Banks providing the offered quotations (but without excluding
         the highest and lowest of such quotations as provided in paragraph (i)
         above); and

                  (iv) if on the Interest Determination Date such Screen Rate is
         unavailable and only one or none of the Reference Banks provides an
         offered quotation, then the Rate of Interest for such Interest Accrual
         Period shall be (a) the Rate of Interest in effect for that Interest
         Accrual Period to which paragraph (i), (ii) or (iii) above shall have
         applied which last preceded such Interest Accrual Period or (b) if
         determinable and if higher, the Reserve Interest Rate. The "Reserve
         Interest Rate" (as defined below) shall be the rate per annum which the
         Agent Bank determines to be either (A) the arithmetic average (rounded
         upward if necessary to the nearest 1/16th of 1%) of the Sterling
         lending rates for loans in an amount approximately equal to the
         principal amount of the Securities which London banks selected by the

                                      B-2



         Agent Bank are quoting, at or about 11:00 a.m. (London time) on the
         Interest Determination Date, for such Interest Accrual Period, to the
         Reference Banks or those of them (being at least two in number) to
         which the quotations are, in the opinion of the Agent Bank, being so
         made plus the Margin or (B) if the Agent Bank cannot determine the
         arithmetic average, the lowest Sterling lending rate which four London
         banks selected by the Agent Bank are quoting, on the Interest
         Determination Date, for such Interest Accrual Period, to leading
         European banks plus the Margin.

                  The Interest Amount shall be determined by (I) applying the
Rate of Interest for such Interest Accrual Period to the principal amount of the
Securities and (ii) multiplying that amount by the actual number of days in such
Interest Accrual Period divided by 365 (or if such Interest Accrual Period ends
after February 28 in a leap year, 366) expressed as a decimal and rounded upward
if necessary to the nearest 1/16th of 1%.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof relating to the interest reset and
remarketing mechanics of this Security after the Initial Reset Date.

                  All payments in respect of this Security and all payments made
pursuant to the Guarantee of this Security shall be made in immediately
available funds at or through the office or agency of the Company maintained for
that purpose in the Borough of Manhattan, The City of New York, and for so long
as this Security shall be listed on the Luxembourg Stock Exchange, in
Luxembourg, in such coin or currency of the United Kingdom or the United States
of America, as the case may be, as at the time of payment is legal tender for
the payment of public and private debt. The Trustee shall make
Sterling-denominated payments on the Senior Notes through a London-based account
of the Trustee.

                  All payments of principal of, and premium, if any, and
interest in respect of this Security and all payments made pursuant to the
Guarantee of this Security shall be made free and clear of, and without
withholding or deduction for or on account of any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed, levied,
collected, withheld or assessed by or within a Taxing Jurisdiction or by or
within any political subdivision thereof or any authority therein or thereof
having power to tax ("Gross-Up Taxes"), unless such withholding or deduction is
required by law. In the event of any such withholding or deduction, the Company
or the Guarantor, as the case may be, shall pay to the Holder such additional
amounts in respect of such withholding or reduction as are necessary so that the
Holder receives the amount that would have been due in the absence of such
withholding or deduction ("Additional Amounts"), except that no such Additional
Amounts shall be payable:

                  (a) to, or to a Person on behalf of, a Holder who is liable
         for such Gross-Up Taxes in respect of this Security or the Guarantee of
         this Security by reason of such Holder or beneficial owner having some
         connection with the relevant Taxing Jurisdiction (including being a
         citizen or resident or national of, or carrying on a business or
         maintaining a permanent establishment in, or being physically present
         in, such Taxing Jurisdiction) other than the mere holding of this
         Security or the receipt of principal of, and premium, if any, and
         interest in respect thereon or in respect of the Guarantee of this
         Security;

                                      B-3



                  (b) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) for payment more than 30
         days after the Relevant Date except to the extent that the Holder would
         have been entitled to such Additional Amounts on presenting this
         Security for payment on the last day of such period of 30 days;

                  (c) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) in a Taxing Jurisdiction
         or, so long as the Senior Notes are listed on the Luxembourg Stock
         Exchange, in Luxembourg;

                  (d) to, or to a Person on behalf of, a Holder who would not be
         liable or subject to the withholding or deduction by making a
         declaration of nonresidence or similar claim for exemption to the
         relevant Taxing Jurisdiction; or

                  (e) to, or to a Person on behalf of, a Holder of a Registered
         Security that is not a Global Security issued pursuant to the request
         of any beneficial owner of an interest in the Security (an "Optional
         Definitive Security Request") following and during the continuance of
         an Event of Default if such Holder (or any predecessor Holder) was an
         owner requesting that such Registered Securities be so issued.

                  Such Additional Amounts will also not be payable where, had
the beneficial owner of the Security (or any interest therein) been the Holder
of the Security, such owner would not have been entitled to payment of
Additional Amounts by reason of any one or more of clauses (a) through (e)
above. If the Company or the Guarantor, as applicable, shall determine that
Additional Amounts will not be payable because of the immediately preceding
sentence, the Company or the Guarantor, as applicable, will inform such Holder
promptly after making such determination setting forth the reason(s) therefor.

                  "Relevant Date" means, in respect of any payment, whichever is
the later of (i) the date on which such payment first becomes due and (ii) if
the full amount payable has not been received in The City of New York by the
Book-Entry Depositary or the Trustee on or prior to such due date, the date on
which, the full amount having been so received, notice to that effect shall have
been given to the bearer hereof in accordance with the Indenture.

                  References to principal of, and premium or interest in respect
of, this Security or any payments pursuant to the Guarantee of this Security
shall be deemed to include any Additional Amounts which may be payable as set
forth in the Indenture or in this Security.

                  The Company shall furnish to the Trustee the official receipts
(or a certified copy of the official receipts) evidencing payment of the
Gross-Up Taxes. Copies of such receipts shall be made available to the Holder of
this Security upon request.

                  All notices regarding the Securities of this Series shall be
published in a leading English language daily newspaper of general circulation
in London. Furthermore, so long as the Securities of this series are listed on
the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange so
require, notices to Holders of Securities of this series will also be published
in a leading newspaper having general circulation in Luxembourg (which is
expected to be the Luxemburger Wort).

                                      B-4



                  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 Security]

                        YORKSHIRE POWER FINANCE 2 LIMITED
                    Reset Senior Notes Due February 15, 2020

                  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, dated as of February 1, 2000 (herein called
the "Original Indenture"), among the Company, Yorkshire Power Group Limited, as
guarantor (the "Guarantor"), and The Bank of New York, as trustee, principal
paying agent, registrar and transfer agent (herein called the "Trustee", which
term includes any successor trustee under the Indenture), as supplemented by the
First Supplemental Indenture, dated as of February 16, 2000 (the "First
Supplemental Indenture"; together with the Original Indenture and any other
supplements thereto, the "Indenture"), among the Company, the Guarantor and the
Trustee 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 Guarantor, 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 (pound)155,000,000; provided, however,
that upon a Conversion Event, such aggregate principal amount shall be limited
to $250,000,000.

                  Certain provisions with respect to the interest rate reset
procedures for the Securities after the Initial Reset Date set forth below are
contained in a Remarketing Agreement (the "Remarketing Agreement") between the
Company, the Guarantor and UBS AG, London Branch or any affiliate thereof, as
Remarketing Agent (the "Remarketing Agent").

                  In accordance with the procedures established in the
Remarketing Agreement and subject to Section 212 of the First Supplemental
Indenture, the interest rate in effect with respect to the Securities
immediately prior to the Initial Reset Date shall be reset on the Initial Reset
Date to equal the Interest Rate to Maturity which shall be effective from and
including the Initial Reset Date to but excluding the final maturity of the
Securities, unless the Company shall exercise the Floating Rate Option in
accordance with the provisions herein. If the Company shall have so exercised
the Floating Rate Option, then the Floating Period Interest Rate shall be reset
in accordance with the Remarketing Agreement on the Reset Date corresponding to
the Floating Rate Period Termination Date to equal the Interest Rate to
Maturity, which shall be effective from and including such Reset Date to but
excluding the final maturity of the Securities.

                  During the period from and including the Fixed Rate Reset Date
to but excluding the final maturity of the Securities, interest on the
Securities shall accrue on principal amount of the Securities at the Interest
Rate to Maturity and shall be payable semi-annually on each Interest Payment
Date, commencing with the first such interest Payment Date following the Fixed
Rate Reset Date; provided, however, that, if any such 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 any such delay). Interest on the Securities from the
Fixed Rate Reset Date shall be computed on the basis of a 360-day year
consisting of twelve 30-day months.

                                      B-7



                  In accordance with procedures established in the Remarketing
Agreement and subject to Section 212 of the First Supplemental Indenture, if the
Company exercises the Floating Rate Option no later than the seventh Business
Day prior to the Floating Rate Spread determination Date by providing notice to
the Trustee and Remarketing Agent, then the Securities shall bear interest at
the Floating Period Interest Rate for each Floating Rate Reset Period in the
Floating Rate Period.

                  During each Floating Rate Reset Period in the Floating Rate
Period, interest on the Securities shall accrue on the Floating Rate Purchase
Price at the Floating Period Interest Rate for such Floating Rate Reset Period
and shall be payable quarterly on each Interest Payment Date, commencing with
the first such Interest Payment Date following the Initial Reset Date. The
Interest Amount for such Floating Rate Reset Period shall be determined by (A)
applying the Floating Period Interest Rate for such Floating Rate Reset Period
to the Floating Rate Purchase Price and (B) multiplying that amount by the
actual number of days in such Floating Rate Reset Period divided by 365 (or, if
such Floating Rate Reset Period ends after February 28 in a leap year, 366)
expressed as a decimal and rounded upward if necessary to the nearest 1/16th of
1%.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Securities shall be automatically tendered, or deemed tendered,
by the Holders thereof to the Remarketing Agent for purchase on the Floating
Rate Period Termination Date. On the Reset Date corresponding to the Floating
Rate Period Termination Date, the interest rate on the Securities shall be reset
to equal the Interest Rate to Maturity in accordance with, and the Securities
shall be remarketed pursuant to, the Remarketing Agreement.

                  The purchase price for the Securities tendered pursuant to the
paragraph above shall equal 100% of the Floating Rate Purchase Price plus

after such declaration of acceleration with respect to the Securities has been
made, but before a judgment or decree for payment of money has been obtained by

and assets substantially as an entirety to, any Person that is organized under

unable to continue as Book-Entry Depositary with respect to a Global security of
this series and no successor Book-Entry Depositary having been appointed by the

Securities of this series having occurred and being continuing and a Holder, in
such circumstance, having requested in writing that a Global Bearer Security of

reasonable measures available to it, subject, as provided in the indenture, to
the delivery by the Company or the Guarantor of an Officers' Certificate stating
that such obligation to pay Additional Amounts cannot be avoided by the Company
or the Guarantor taking reasonable measures available to it.

Holders of a majority in aggregate principal amount of the Securities at the
time Outstanding of all series to be affected (voting as a class). The Indenture

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

Holder of this Security shall be conclusive and binding upon such Holder and

Company, which is absolute and unconditional, to pay the principal of, and
premium, if any, and interest in respect of this Security at the times, place
and rate, and in the coin or currency, herein prescribed.

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
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 Security for registration of
transfer, 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 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.

                  When a successor assumes all the obligations of its
predecessor under the Securities of this series and the Indenture in accordance
with the terms of the Indenture, the predecessor will be released from those
obligations.

                  The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Securities of this series and
may otherwise deal with the Company, the Guarantor or their respective
Affiliates as if it were not the Trustee.

                  No stockholder, director, officer, employee, incorporator or
Affiliate of the Company or the Guarantor shall have any liability for any
obligation of the Company or the Guarantor under the Securities of this series
or the Indenture or for any claim based on, in respect of or by reason of, such
obligations of their creation. Each Holder of the Securities of this series by
accepting Securities of this series waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the
Securities of this series.
