State of New York, whose post office address is 60 Wall Street, 24th Floor, New York, New York 10005 (hereinafter called the “Trustee”),
as the ________________________ supplemental indenture (hereinafter called the “________________________ Supplemental
Indenture”) to the Mortgage and Deed of Trust, dated as of January 1, 1944 (hereinafter called the “Mortgage”),
made and entered into by FPL, the Trustee and The Florida National Bank of Jacksonville, as Co-Trustee (now resigned), the Trustee
now acting as the sole trustee under the Mortgage, which Mortgage was executed and delivered by FPL to secure the payment of bonds
issued or to be issued under and in accordance with the provisions thereof, reference to which Mortgage is hereby made, this ________________________
Supplemental Indenture being supplemental thereto;

 

Whereas,
by an instrument, dated as of April 15, 2002,
filed with the Banking Department of the State of New York, Bankers Trust Company effected a corporate name change pursuant to
which, effective such date, it is known as Deutsche Bank Trust Company Americas; and

 

Whereas,
FPL has transferred to New Hampshire Transmission,
LLC, a Delaware limited liability company, all of FPL’s property located in the State of New Hampshire that previously was
subject to the lien of the Mortgage, and the Trustee by instrument dated June 29, 2010 (the “Release”) released
such property from the lien of the Mortgage, and released and discharged the supplemental indentures and mortgages recorded in
the State of New Hampshire listed on Exhibit B to the Release; and

 

Whereas,
Section 8 of the Mortgage
provides that the form of each series of bonds (other than the first series) issued thereunder shall be established by Resolution
of the Board of Directors of FPL and that the form of such series, as established by said Board of Directors, shall specify the
descriptive title of the bonds and various other terms thereof, and may also contain such provisions not inconsistent with the
provisions of the Mortgage as the Board of Directors may, in its discretion, cause to be inserted therein expressing or referring
to the terms and conditions upon which such bonds are to be issued and/or secured under the Mortgage; and

 

Whereas,
Section 120 of the Mortgage
provides, among other things, that any power, privilege or right expressly or impliedly reserved to or in any way conferred upon
FPL by any provision of the Mortgage, whether such power, privilege or right is in any way restricted or is unrestricted, may
be in whole or in part waived or surrendered or subjected to any restriction if at the time unrestricted or to additional restriction
if already restricted, and FPL may enter into any further covenants, limitations or restrictions for the benefit of any one or
more series of bonds issued thereunder, or FPL may cure any ambiguity contained therein, or in any supplemental indenture, or
may establish the terms and provisions of any series of bonds other than the first series, by an instrument in writing executed
and acknowledged by FPL in such manner as would be necessary to entitle a conveyance of real estate to be recorded in all of the
states in which any property at the time subject to the Lien of the Mortgage shall be situated; and

FPL now desires to create the series of bonds
described in Article I hereof and to add to its covenants and agreements contained in the Mortgage certain
other covenants and agreements to be observed by it and to alter and amend in certain respects the covenants and provisions contained
in the Mortgage; and

 

Whereas,

ARTICLE
I

_____________________ Series of Bonds

 

Section
1.     1(I) There shall be a series of bonds designated “____% Series due _________,
____”, herein sometimes referred to as the “_____________________ Series”, each of which shall also bear
the descriptive title First Mortgage Bond, and the form thereof, which shall be established by Resolution of the Board of Directors
of FPL, shall contain suitable provisions with respect to the matters hereinafter in this Section specified. Bonds of the _____________________
Series shall mature on __________, ____ and shall be issued as fully registered bonds in denominations of ____________ Dollars
and, at the option of FPL, in integral multiples of ____________ Dollars (the exercise of such option to be evidenced by the execution
and delivery thereof); they shall bear interest at the rate of ____% per annum, payable semi-annually on _______ and _________
of each year (each an “Interest Payment Date”) commencing on _____________; the principal of and interest on
each said bond to be payable at the office or agency of FPL in the Borough of Manhattan, The City of New York, in such coin or
currency of the United States of America as at the time of payment is legal tender for public and private debts. Bonds of the
_____________________ Series shall be dated as in Section 10 of the Mortgage provided. The record date for
payments of interest on any Interest Payment Date shall be the close of business on (1) the Business Day (as defined below) immediately
preceding such Interest Payment Date so long as all of the bonds of the _____________________ Series are held by a securities
depository in book-entry only form or (2) the 15th calendar day immediately preceding such Interest Payment Date if any of the
bonds of the _____________________ Series are not held by a securities depository in book-entry only form. Interest on the bonds
of the _____________________ Series will accrue from and including ____________, ____ to but excluding _______, ____ and, thereafter,
from and including the last Interest Payment Date to which interest has been paid or duly provided for (and if no interest has
been paid on the bonds of the _____________________ Series, from ________________) to but excluding the next succeeding Interest
Payment Date. No interest will accrue on a bond of the _____________________ Series for the day on which such bond matures. The
amount of interest payable for any period will be computed on the basis of a 360-day year consisting of twelve 30-day months.
The amount of interest payable for any period shorter than a full semi-annual period for which interest is computed will be computed
on the basis of the number of days in the period using 30-day calendar months. If any date on which interest, principal or premium,
if any, is payable on the bonds of the _____________________ Series falls on a day that is not a Business Day, then payment of
the interest, principal or premium payable on that date will be made on the next succeeding day which is a Business Day, and without
any interest or other payment in respect of such delay. A “Business Day” is any day that is not a Saturday,
a Sunday, or a day on which banking institutions or trust companies in New York City are generally authorized or required by law
or executive order to remain closed.

payable [on the dates established on the Issue Date [or the Original Interest Accrual Date] with respect to such bonds and shall

payable on such interest payment date, notwithstanding the cancellation of such bond of the __________________ Series, upon any
transfer or exchange thereof subsequent to the Record Date and on or prior to such interest payment date. If the Issue Date [or
the Original Interest Accrual Date] of the bonds of the __________________ Series of a designated interest rate and maturity is
after the Record Date, such bonds shall bear interest from the Issue Date [or the Original Interest Accrual Date] but payment
of interest shall commence on the second interest payment date succeeding the Issue Date [or the Original Interest Accrual Date].
 “Record Date” for bonds of the __________________ Series which bear interest at a fixed rate shall mean ___________________
for interest payable ___________________ and ___________________ for interest payable ___________________, and for bonds of the
___________________ Series which bear interest at a variable rate, the date 15 calendar days prior to any interest payment date,
provided that, interest payable on the maturity date will be payable to the person to whom the principal thereof shall
be payable. “Issue Date” [or “Original Interest Accrual Date”] with respect to bonds of the __________________
Series of a designated interest rate and maturity [unless a Resolution filed with the Trustee on or before such date shall specify
another date from which interest shall accrue, then such other date for bonds of such designated interest rate and maturity.]
shall mean the date of first authentication of bonds of such designated interest rate and maturity.] The principal of and interest
on each said bond is payable at the office or agency of FPL in the Borough of Manhattan, The City of New York, in such coin or
currency of the United States of America as at the time of payment is legal tender for public and private debts. Bonds of the
__________________ Series shall be dated as in Section 10 of the Mortgage provided.

Series due _______________, all bonds of all series issued and to be issued under and equally secured (except insofar as any sinking

including the ________________________ Supplemental Indenture dated as of _________________, called the “Mortgage”),
dated as of January 1, 1944, executed by the Company to Deutsche Bank Trust Company Americas (formerly known as Bankers Trust

in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes
and neither the Company nor the Corporate Trustee shall be affected by any notice to the contrary.

 

In
the manner prescribed in the Mortgage, any bonds of this series, upon surrender thereof for exchange, at the office or agency
of the Company in the Borough of Manhattan, The City of New York, together with a written instrument of transfer wherever required
by the Company duly executed by the registered owner or by his duly authorized attorney, are exchangeable for a like aggregate
principal amount of bonds of the same series and maturity of other authorized denominations.

As
provided in the Mortgage, the Company shall not be required to make transfers or exchanges of bonds of any series for a period
of ten days next preceding any interest payment date for bonds of said series, or next preceding any designation of bonds of said
series to be redeemed, and the Company shall not be required to make transfers or exchanges of any bonds designated in whole or
in part for redemption.

or future subscriber to the capital stock, or any stockholder, officer or director of the Company or of any predecessor or successor
corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any rule of law,
statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers,
stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise
waived and released by the terms of the Mortgage.

initial and future holder of this bond, by its acquisition of an interest in this bond, irrevocably (a) consents to the amendments
set forth in Article II of the One Hundred Twenty-Eighth Supplemental Indenture, dated as of June 15, 2018, without any other

irrevocable instructions to vote and deliver written consents on behalf of such holder in favor of such amendments at any bondholder
meeting, in lieu of any bondholder meeting, in any consent solicitation or otherwise.

bond shall not become obligatory until Deutsche Bank Trust Company Americas, the Corporate Trustee under the Mortgage, or its
successor thereunder, shall have signed the form of authentication certificate endorsed hereon.
