Ladies and Gentlemen:

 

The parties hereto
hereby enter into this side letter agreement (this “Agreement”), by and between Thunder Bridge Acquisition II
Ltd. (the “Company”) and Monroe Capital LLC (the “Subscriber”). For good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the Subscriber and the Company hereby agree as follows:

 

1. The
Company hereby grants the Subscriber a right of first refusal (“ROFR”) with respect to fifty-one percent of
any issuances of senior debt, second lien debt, last out senior and junior lien debt or holdco unsecured debt, including each tranche
thereof (collectively, “Debt”), directly or indirectly, by the Company or any of its subsidiaries (including
by way of assumption), in connection with the Company’s initial business combination (the “Business Combination”
as described in the registration statement relating to the Company’s initial public offering (the “IPO”))
and the right to be lead agent and arranger with respect to such Debt. The Company shall notify the Subscriber of the principal
terms of any proposed issuance of Debt in connection with the Business Combination and provide the Subscriber with a draft merger
agreement or analogous acquisition agreement containing all material terms of the Business Combination (the “Acquisition
Agreement”). Such notice shall contain an offer to allow the Subscriber or, at the Subscriber’s option, one or
more of its affiliates, to make at least fifty-one percent of such loan or purchase at least fifty-one percent of such Debt securities
and to act as lead agent and arranger. The Company shall provide reasonable access to due diligence information to facilitate the
Subscriber’s decision as to whether or not to exercise the ROFR, subject to entering into a customary confidentiality agreement.
If the Subscriber chooses to accept, the Subscriber shall have ten days from the date of such notice to provide a commitment letter
accepting such right of first refusal; provided, however, that if there has been a material change to the economic
terms of the Acquisition Agreement that would reasonably be expected to affect a lender’s underwriting decision, then the
ten day period shall be extended such that there shall be at least three additional business days from the date that the Subscriber
is notified of such material change. In the event the Subscriber does not elect to make a loan or purchase such Debt securities
within such ten days (as the same may be extended), the Company or such subsidiary shall be free to make such loan or sell such
Debt securities on the terms contained in such notice.

 

2. Notwithstanding
anything to the contrary in this Agreement, the Company shall not, and shall cause its affiliates not to, publicly identify the
Subscriber or any of its affiliates by name or identifiable description, or include the name or identifiable description of the
Subscriber or any of its affiliates in any press release, filing with the U.S. Securities and Exchange Commission or any regulatory
agency or trading market, or any other public disclosure without the prior written consent of the Subscriber, both as to the name
of the Subscriber and as to any disclosure relating to the Subscriber.

 

     

     

    

 

3. THIS
AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE PRINCIPLES
OF CONFLICTS OF LAWS THAT WOULD OTHERWISE REQUIRE THE APPLICATION OF THE LAW OF ANY OTHER STATE. 

 

4. This
Agreement may be executed in one or more counterparts (including by facsimile or electronic mail or in .pdf) and by different parties
in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed
and delivered shall be construed together and shall constitute one and the same agreement.

 

5. This
Agreement may not be modified, waived or terminated except by an instrument in writing, signed by the party against whom enforcement
of such modification, waiver or termination is sought.

 

6. This
Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties,
both written and oral, among the parties, with respect to the subject matter hereof. This Agreement shall not confer any rights
or remedies upon any person other than the parties hereto, and their respective successor and assigns.

 

7. This
Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors,
legal representatives and permitted assigns, and the agreements and acknowledgments contained herein shall be deemed to be made
by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns.

 

8. If
any provision of this Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

 

9. The
Subscriber hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any distribution
of or from the trust account (the “Trust Account”) to be established by the Company in which substantially all
of the proceeds of the IPO (including the deferred underwriters discounts and commissions) and of the sale of the private placement
warrants by the Company are to be deposited, as described in greater detail in the registration statement related to the IPO, and
hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason
whatsoever. This Section 9 shall not apply to any Claims the Subscriber may have with respect to its ownership of the Company’s
public securities or the right to receive the return of escrowed funds deposited into the Trust Account prior to the IPO.

 

If the foregoing is
in accordance with your understanding, please sign and return to us one counterpart hereof, and upon the acceptance hereof by the
Subscriber and the Company, this Agreement and such acceptance hereof shall constitute a binding agreement between the parties
hereto.

That in consideration

these presents, the receipt whereof is hereby acknowledged, the Company hereby covenants and agrees with the Trustee and its successors
in the trust under the Indenture as follows:

 

PART
One. 

 

SECTION 1.       
Bonds of the 2.45% Series

 

Section 1.1.        The
Company hereby creates a new series of bonds to be issued under and secured by the Indenture and known as its First and Refunding
Mortgage Bonds, 2.45% Series due 2029 (herein called “bonds of the 2.45% Series”) and the Company hereby establishes,
determines and fixes the terms and provisions of the bonds of the 2.45% Series as hereinafter in this Section 1 set forth.

 

Each bond of the 2.45%
Series shall be dated the date of its authentication (except that if any such bond shall be authenticated on any interest payment
date, it shall be dated the following day) and interest shall be payable on the principal represented thereby commencing February
15, 2020, from February 15 or August 15, as the case may be, next preceding the date thereof to which interest has been paid, unless
such date of authentication is prior to February 15, 2020, in which case interest shall be payable from August 14, 2019; provided,
however, that interest shall be payable on each bond of the 2.45% Series authenticated after the record date (as defined
in the next succeeding paragraph of this Section 1.1) with respect to any interest payment date and prior to such interest payment
date, only from such interest payment date.

 

Interest on any bond
of the 2.45% Series shall be paid to the person who, according to the bond register of the Company, is the registered holder of
such bond of the 2.45% Series at the close of business on the applicable record date, and such interest payments shall be made
by check mailed to such registered holder at his last address shown on such bond register or, at the option of the Company, by
wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to
the Trustee at least sixteen (16) days prior to the date of payment by the Person entitled thereto (provided, that if the
bonds of the 2.45% Series are represented by Global Securities held by the Depositary, payment may be made pursuant to the procedures
of the Depositary); provided, however, that, if the Company shall default in the payment of the interest due on any
interest payment date on any bond of the 2.45% Series, such defaulted interest shall be paid to the registered holder of such bond
(or any bond or bonds of the 2.45% Series issued upon transfer, exchange or substitution thereof) on the date of subsequent payment
of such defaulted interest or, at the election of the Company, to the person in whose name such bond (or any bond or bonds of the
2.45% Series issued upon transfer, exchange or substitution thereof) is registered on a subsequent record date established by notice
given by mail by or on behalf of the Company to the holders of all bonds of the 2.45% Series not less than ten (10) days preceding
such subsequent record date. The term “record date” as used in this Section 1.1 shall mean, with respect to any semi-annual
interest payment date, (i) the close of business on the business day immediately preceding such interest payment date so long as
the bonds of the 2.45% Series remain in book-entry only form or (ii) the fifteenth calendar day immediately preceding such interest
payment date if any of the bonds of the 2.45% Series do not remain in book-entry only form, in each case, whether or not a business
day, or, in the case of a payment of defaulted interest, the close of business on any subsequent record date established as provided
above.

 

    	 	4	 

     

    

 

Section 1.2.         All
bonds of the 2.45% Series shall mature as to principal on August 15, 2029 and shall bear interest at a rate of 2.45% per annum,
payable semi-annually on the 15th day of February and August in each year, commencing on the 15th day of February, 2020. Interest
on the bonds of the 2.45% Series will be computed on the basis of a 360-day year consisting of twelve 30-day months.

 

Section 1.3.         The
bonds of the 2.45% Series shall be fully registered bonds, without coupons, in denominations of two thousand dollars ($2,000)
and integral multiples of one thousand dollars ($1,000) in excess thereof, all such bonds to be numbered, and shall be transferable
and exchangeable as provided in the form of bond set forth as Exhibit A to this supplemental indenture. The provisions of §1.19
and any other provision in the Indenture in respect of coupon bonds or reservation of coupon bond numbers shall be inapplicable
to the bonds of the 2.45% Series.

 

Section 1.4.         At
any time before May 15, 2029 (the “2029 Par Call Date”), the bonds of the 2.45% Series may be redeemed at the option
of the Company, in whole or in part and from time to time, at a redemption price equal to the greater of (1) 100% of the principal
amount of the bonds of the 2.45% Series to be redeemed and (2) the sum of the present values of the remaining scheduled payments
of principal and interest on the bonds of the 2.45% Series being redeemed that would be due if the bonds of the 2.45% Series matured
on the 2029 Par Call Date (exclusive of interest accrued to the redemption date) discounted to the redemption date on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, plus, in either
case, accrued and unpaid interest on the principal amount of the bonds of the 2.45% Series being redeemed to, but excluding, the
date of such redemption. The Company shall notify the Trustee of the redemption price with respect to any redemption pursuant
to this paragraph promptly after the calculation thereof. The Trustee shall not be responsible for calculating said redemption
price.

 

At any time on or after
the 2029 Par Call Date, the bonds of the 2.45% Series may be redeemed at the option of the Company, in whole or in part and from
time to time, at a redemption price equal to 100% of the principal amount of the bonds of the 2.45% Series to be redeemed plus
accrued and unpaid interest on the principal amount being redeemed to, but excluding, the date of such redemption.

 

The bonds of the 2.45%

SECTION 2.       
Bonds of the 3.20% Series

 

Section 2.1.        The
Company hereby creates a new series of bonds to be issued under and secured by the Indenture and known as its First and Refunding
Mortgage Bonds, 3.20% Series due 2049 (herein called “bonds of the 3.20% Series”) and the Company hereby establishes,
determines and fixes the terms and provisions of the bonds of the 3.20% Series as hereinafter in this Section 2 set forth.

 

Each bond of the 3.20%
Series shall be dated the date of its authentication (except that if any such bond shall be authenticated on any interest payment
date, it shall be dated the following day) and interest shall be payable on the principal represented thereby commencing February
15, 2020, from February 15 or August 15, as the case may be, next preceding the date thereof to which interest has been paid, unless
such date of authentication is prior to February 15, 2020, in which case interest shall be payable from August 14, 2019; provided,
however, that interest shall be payable on each bond of the 3.20% Series authenticated after the record date (as defined
in the next succeeding paragraph of this Section 2.1) with respect to any interest payment date and prior to such interest payment
date, only from such interest payment date.

 

    	 	6	 

     

    

 

Interest on any bond
of the 3.20% Series shall be paid to the person who, according to the bond register of the Company, is the registered holder of
such bond of the 3.20% Series at the close of business on the applicable record date, and such interest payments shall be made
by check mailed to such registered holder at his last address shown on such bond register or, at the option of the Company, by
wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to
the Trustee at least sixteen (16) days prior to the date of payment by the Person entitled thereto (provided, that if the
bonds of the 3.20% Series are represented by Global Securities held by the Depositary, payment may be made pursuant to the procedures
of the Depositary); provided, however, that, if the Company shall default in the payment of the interest due on any
interest payment date on any bond of the 3.20% Series, such defaulted interest shall be paid to the registered holder of such bond
(or any bond or bonds of the 3.20% Series issued upon transfer, exchange or substitution thereof) on the date of subsequent payment
of such defaulted interest or, at the election of the Company, to the person in whose name such bond (or any bond or bonds of the
3.20% Series issued upon transfer, exchange or substitution thereof) is registered on a subsequent record date established by notice
given by mail by or on behalf of the Company to the holders of all bonds of the 3.20% Series not less than ten (10) days preceding
such subsequent record date. The term “record date” as used in this Section 2.1 shall mean, with respect to any semi-annual
interest payment date, (i) the close of business on the business day immediately preceding such interest payment date so long as
the bonds of the 3.20% Series remain in book-entry only form or (ii) the fifteenth calendar day immediately preceding such interest
payment date if any of the bonds of the 3.20% Series do not remain in book-entry only form, in each case, whether or not a business
day, or, in the case of a payment of defaulted interest, the close of business on any subsequent record date established as provided
above.

 

Section 2.2.        All
bonds of the 3.20% Series shall mature as to principal on August 15, 2049 and shall bear interest at a rate of 3.20% per annum,
payable semi-annually on the 15th day of February and August in each year, commencing on the 15th day of February, 2020. Interest
on the bonds of the 3.20% Series will be computed on the basis of a 360-day year consisting of twelve 30-day months.

 

Section 2.3.        The
bonds of the 3.20% Series shall be fully registered bonds, without coupons, in denominations of two thousand dollars ($2,000)
and integral multiples of one thousand dollars ($1,000) in excess thereof, all such bonds to be numbered, and shall be transferable
and exchangeable as provided in the form of bond set forth as Exhibit B to this supplemental indenture. The provisions of §1.19
and any other provision in the Indenture in respect of coupon bonds or reservation of coupon bond numbers shall be inapplicable
to the bonds of the 3.20% Series.

 

Section 2.4.        At
any time before February 15, 2049 (the “2049 Par Call Date”), the bonds of the 3.20% Series may be redeemed at the
option of the Company, in whole or in part and from time to time, at a redemption price equal to the greater of (1) 100% of the
principal amount of the bonds of the 3.20% Series to be redeemed and (2) the sum of the present values of the remaining scheduled
payments of principal and interest on the bonds of the 3.20% Series being redeemed that would be due if the bonds of the 3.20%
Series matured on the 2049 Par Call Date (exclusive of interest accrued to the redemption date) discounted to the redemption date
on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points,
plus, in either case, accrued and unpaid interest on the principal amount of the bonds of the 3.20% Series being redeemed to,
but excluding, the date of such redemption. The Company shall notify the Trustee of the redemption price with respect to any redemption
pursuant to this paragraph promptly after the calculation thereof. The Trustee shall not be responsible for calculating said redemption
price.

 

At any time on or after
the 2049 Par Call Date, the bonds of the 3.20% Series may be redeemed at the option of the Company, in whole or in part and from
time to time, at a redemption price equal to 100% of the principal amount of the bonds of the 3.20% Series to be redeemed plus
accrued and unpaid interest on the principal amount being redeemed to, but excluding, the date of such redemption.

 

The bonds of the 3.20%
Series are also subject to redemption through the operation of the Replacement Fund provided in Part Two of this supplemental indenture
or through the application of moneys paid to the Trustee pursuant to the provisions of §5.05 of the Indenture, at any time
or from time to time prior to maturity, upon prior notice as hereinafter provided, at the redemption prices specified in the fifth
paragraph of the reverse side of the form of bond set forth as Exhibit B to this supplemental indenture, together with interest
accrued thereon to the date fixed for redemption thereof.

 

    	 	7	 

     

    

 

In the event that any

register of the Company. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the holder receives such notice; and failure duly to give such notice by mail, or any defect in such notice,
to the holder of any bond designated for redemption as a whole or in part shall not affect the validity of the proceedings for
the redemption of any other bond. No publication of notice of such redemption shall be required.

2029, of an authorized issue of bonds of the Company, without limit as to aggregate principal amount, designated generally as First
and Refunding Mortgage Bonds, all issued and to be issued under and equally and ratably secured by a First and Refunding Mortgage
dated as of December 1, 1927, duly executed by Duke Power Company, a New Jersey corporation (hereinafter called the “New
Jersey Company”), to Guaranty Trust Company of New York, as Trustee (The Bank of New York Mellon Trust Company, N.A., as
successor trustee), as supplemented and modified by indentures supplemental thereto, including a supplemental indenture dated as
of August 14, 2019 providing for said series (said First and Refunding Mortgage as so supplemented and modified being hereinafter
referred to as the “Indenture”), to which Indenture reference is made for a description of the property mortgaged,
the nature and extent of the security, the rights of the holders of the bonds in respect thereof, the terms and conditions upon
which the bonds are secured and the restrictions subject to which additional bonds secured thereby may be issued. To the extent
permitted by, and as provided in, the Indenture, modifications or alterations of the Indenture, or of any indenture supplemental
thereto, and of the rights and obligations of the Company and of the holders of the bonds, may be made with the consent of the
Company by the affirmative vote, or with the written consent, of the holders of not less than 66 2/3% in principal amount of the
bonds then outstanding, and by the affirmative vote, or with the written consent, of the holders of not less than 66 2/3% in principal
amount of the bonds of any series then outstanding and affected by such modification or alteration, in case one or more but less

Indenture; provided that any supplemental indenture may be modified in accordance with the provisions contained therein
for its modification; and provided, further, that no such modification or alteration shall be made which will affect the terms
of payment of the principal of, or interest or premium on, this bond, or the right of any bondholder to institute suit for the
enforcement of any such payment on or after the respective due dates expressed in this bond, or reduce the percentage required
for the taking of any such action. Any such affirmative vote of, or written consent given by, any holder of this bond is binding
upon all subsequent holders hereof as provided in the Indenture.

 

In case an event of
default as defined in the Indenture shall occur, the principal of all the bonds outstanding thereunder may become or be declared
due and payable at the time, in the manner and with the effect provided in the Indenture.

 

At any time before

whole or in part and from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of
the bonds of this series to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal
and interest on such bonds being redeemed that would be due if the bonds of this series matured on the Par Call Date (exclusive
of interest accrued to the redemption date), discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate plus 15 basis points, plus, in either case, accrued and unpaid interest on the principal
amount of the bonds of this series being redeemed to, but excluding, the date of such redemption.

 

At
any time on or after the Par Call Date, the bonds of this series may be redeemed at the option of the Company, in whole or in part
and from time to time, at a redemption price equal to 100% of the principal amount of the bonds of this series to be redeemed
plus accrued and unpaid interest on the principal amount being redeemed to, but excluding, the date of such redemption.

 

“Business
day” means any day other than a day on which banks in New York City are required or authorized to be closed.

“Comparable Treasury Issue”
means the United States Treasury security selected by the Quotation Agent as having an actual or interpolated maturity comparable
to the remaining term of the bonds of this series to be redeemed (assuming, for this purpose, that the bonds of this series matured
on the Par Call Date), that would be utilized at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such bonds.

 

“Comparable Treasury Price”
means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Quotation Agent obtains
fewer than four of such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations as determined
by the Company.

 

“Quotation Agent”
means one of the Reference Treasury Dealers appointed by the Company.

 

“Reference
Treasury Dealer” means each of Barclays Capital Inc., BNP Paribas Securities Corp., a Primary Treasury Dealer (as
defined below) selected by PNC Capital Markets LLC and a Primary Treasury Dealer selected by SunTrust Robinson Humphrey, Inc.,
plus one other financial institution appointed by the Company at the time of any redemption, or their respective affiliates or
successors, each of which is a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”);
provided, however, that if any of the foregoing or their affiliates or successors shall cease to be a Primary Treasury Dealer,
the Company shall substitute therefor another Primary Treasury Dealer.

 

“Reference Treasury Dealer
Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the
Quotation Agent, 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 the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third
business day preceding such redemption date.

 

“Treasury Rate” means,
with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity
(on a day count basis) of the Comparable Treasury Issue, assuming 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
bonds of this series are also subject to redemption for the Replacement Fund for bonds of this series provided for in the supplemental
indenture dated as of August 14, 2019, providing for this series, or upon application of moneys arising from a taking of any
of the mortgaged property by eminent domain or similar action, at any time or from time to time prior to maturity, at 100%
of their principal amount, in each case together with accrued and unpaid interest to, but excluding, the date fixed for redemption.

 

Redemption is in every
case to be effected at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon at least ten,
but not more than sixty, days’ prior notice, given by mail as more fully provided in the Indenture.

 

If this bond or any
portion hereof ($2,000 and integral multiples of $1,000 in excess thereof) is called for redemption and payment is duly provided,
this bond or such portion thereof shall cease to bear interest from and after the date fixed for such redemption.

  

    	 	A-5	 

     

    

 

This bond is transferable,
as provided in the Indenture, by the registered owner hereof in person or by duly authorized attorney, at the office or agency
of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon a
new bond of the same series and of like aggregate principal amount will be issued to the transferee in exchange herefor as provided
in the Indenture; or the registered owner of this bond, at his option, may surrender the same for cancellation at said office or
agency of the Company and receive in exchange herefor the same aggregate principal amount of bonds of the same series of authorized
denominations; all subject to the terms of the Indenture but without payment of any charges other than a sum sufficient to reimburse
the Company for any stamp taxes or other governmental charges incident thereto.

  

This bond is a company
obligation only and no recourse whatsoever, either directly or through the Company or any trustee, receiver, assignee or any other
person, shall be had for the payment of the principal of or premium, if any, or interest on this bond, or for the enforcement of
any claim based hereon, or otherwise in respect hereof or of the Indenture, against any promoter, subscriber to the capital stock,
incorporator, or any past, present or future stockholder, member, officer or director of the Company as such, or of any successor
or predecessor corporation or entity, whether by virtue of any constitutional provision, statute or rule of law, or by the
enforcement of any assessment, penalty, subscription or otherwise, any and all such liability of promoters, subscribers, incorporators,
stockholders, members, officers and directors being waived and released by each successive holder hereof by the acceptance of this
bond, and as a part of the consideration for the issue hereof, and being likewise waived and released by the terms of the Indenture.

and Refunding Mortgage Bonds, all issued and to be issued under and equally and ratably secured by a First and Refunding Mortgage
dated as of December 1, 1927, duly executed by Duke Power Company, a New Jersey corporation (hereinafter called the “New
Jersey Company”), to Guaranty Trust Company of New York, as Trustee (The Bank of New York Mellon Trust Company, N.A., as
successor trustee), as supplemented and modified by indentures supplemental thereto, including a supplemental indenture dated as
of August 14, 2019 providing for said series (said First and Refunding Mortgage as so supplemented and modified being hereinafter
referred to as the “Indenture”), to which Indenture reference is made for a description of the property mortgaged,
the nature and extent of the security, the rights of the holders of the bonds in respect thereof, the terms and conditions upon
which the bonds are secured and the restrictions subject to which additional bonds secured thereby may be issued. To the extent
permitted by, and as provided in, the Indenture, modifications or alterations of the Indenture, or of any indenture supplemental
thereto, and of the rights and obligations of the Company and of the holders of the bonds, may be made with the consent of the
Company by the affirmative vote, or with the written consent, of the holders of not less than 66 2/3% in principal amount of the
bonds then outstanding, and by the affirmative vote, or with the written consent, of the holders of not less than 66 2/3% in principal
amount of the bonds of any series then outstanding and affected by such modification or alteration, in case one or more but less
than all of the series of bonds then outstanding under the Indenture are so affected, evidenced, in each case, as provided in the
Indenture; provided that any supplemental indenture may be modified in accordance with the provisions contained therein
for its modification; and provided, further, that no such modification or alteration shall be made which will affect the terms
of payment of the principal of, or interest or premium on, this bond, or the right of any bondholder to institute suit for the
enforcement of any such payment on or after the respective due dates expressed in this bond, or reduce the percentage required
for the taking of any such action. Any such affirmative vote of, or written consent given by, any holder of this bond is binding
upon all subsequent holders hereof as provided in the Indenture.

 

In case an event of
default as defined in the Indenture shall occur, the principal of all the bonds outstanding thereunder may become or be declared
due and payable at the time, in the manner and with the effect provided in the Indenture.

of the bonds of this series to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal
and interest on such bonds being redeemed that would be due if the bonds of this series matured on the Par Call Date (exclusive
of interest accrued to the redemption date), discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting

means the United States Treasury security selected by the Quotation Agent as having an actual or interpolated maturity comparable
to the remaining term of the bonds of this series to be redeemed (assuming, for this purpose, that the bonds of this series matured

pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such bonds.

  

“Comparable Treasury Price”
means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Quotation Agent obtains

provided, however, that if any of the foregoing or their affiliates or successors shall cease to be a Primary Treasury Dealer,
the Company shall substitute therefor another Primary Treasury Dealer.

business day preceding such redemption date.

 

“Treasury Rate” means,

The
bonds of this series are also subject to redemption for the Replacement Fund for bonds of this series provided for in the supplemental
indenture dated as of August 14, 2019, providing for this series, or upon application of moneys arising from a taking of any
of the mortgaged property by eminent domain or similar action, at any time or from time to time prior to maturity, at 100%
of their principal amount, in each case together with accrued and unpaid interest to, but excluding, the date fixed for redemption.

 

Redemption is in every
case to be effected at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon at least ten,

denominations; all subject to the terms of the Indenture but without payment of any charges other than a sum sufficient to reimburse
the Company for any stamp taxes or other governmental charges incident thereto.
