For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company will calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company will select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security will be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Trustee” means the Person named as the “Trustee” in the first paragraph of this Supplemental Indenture until a successor Trustee shall have become such pursuant to the applicable provisions of the Indenture, and thereafter “Trustee” shall mean or include each Person who is then a Trustee hereunder.

Section 2.01. Designation and Amount; Payments. The Notes are hereby created and authorized as a single series of Securities under the Original Indenture. The Notes shall be designated as the “6.250% Senior Notes due 2029”. The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is initially limited to $750,000,000, subject to Section 2.06 and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 2.09, Section 2.10, Section 2.12 and Section 10.05 of the Original Indenture and Section 7.03 of this Supplemental Indenture.

The principal amount of Notes then outstanding shall be payable on the Maturity Date. The Notes will bear interest at a rate of 6.250% per year from May 28, 2024, or from the most recent date on which interest had been paid or provided for, until the principal thereof is paid or made available for payment. Interest is payable on each Interest Payment Date, beginning on November 28, 2024, to the Person in whose name a Note is registered on the Security Register at the close of business on the Regular Record Date immediately preceding the applicable Interest Payment Date. If any Interest Payment Date, the Maturity Date or a Redemption Date falls on a day that is not a Business Day, the required payment shall be made on the next succeeding Business Day and no interest on such payment shall accrue in respect of such delay.

The Notes shall be the direct, unsecured obligations of the Company and will rank equally with each other and with all other existing and future unsecured and unsubordinated Indebtedness of the Company.

Section 2.02. Form of Notes. The Notes shall be substantially in the form set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of the Indenture, expressly agree to such terms and provisions and to be bound thereby.

Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of the Indenture as may be required by the Note Custodian or the Depository, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject.

Each Global Note shall represent such principal amount of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of Outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of Outstanding Notes represented thereby may from time to time be increased or reduced to reflect redemptions, repurchases, transfers or exchanges permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in the amount of Outstanding Notes represented thereby shall be made on the Schedule of Exchanges of Notes to such Global Note by the Trustee or the Note Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with the Indenture.

The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note, shall be effected through the Depository (but not the Trustee or the Note Custodian) in accordance with the Indenture (including the restrictions on transfer set forth herein) and the Applicable Procedures of the Depository therefor.

(b) The Depository shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company, a New York corporation (“DTC”), to act as Depository with respect to each Global Note. Initially, each Global Note shall be issued to the Depository, registered in the name of Cede & Co., as the nominee of the Depository, and deposited with The Bank of New York Mellon Trust Company, N.A. as custodian for DTC.

(c) Section 2.09(d) of the Original Indenture is hereby amended and restated in full, with respect to the Notes, to read as follows:

“Physical Notes shall be issued and delivered by the Company (i) to each Person that DTC identifies as a beneficial owner of the related Securities only if (a) DTC has notified the Company that it is unwilling or unable to continue as depository for the Global Securities of the relevant series and a successor depository is not appointed within 90 calendar days or (b) DTC ceases to be registered as a clearing agency under the Exchange Act and a successor depository is not appointed within 90 calendar days or (ii) if an Event of Default with respect to the Securities of any series has occurred and is continuing, to each beneficial owner who requests that its beneficial interests in the Securities be exchanged for Securities in definitive form.”

(d) Notwithstanding anything to the contrary in the Indenture (including, without limitation, Section 1.01, Section 2.01, Section 2.09 and Section 2.15 of the Original Indenture) or the Notes, following the occurrence and during the continuance of an Event of Default, any beneficial owner of a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depository or any other Person, such beneficial owner’s right to exchange its beneficial interest in such Global Note for a Physical Note in accordance with Section 1.05 of the Original Indenture.

(e) At such time as all interests in a Global Note have been canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with Applicable Procedures. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depository and the Note Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the Schedule of Exchanges of Notes to such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such reduction or increase.

Section 2.04. Cancellation of Surrendered Notes. The Company shall cause all Notes surrendered for payment, repurchase (including pursuant to Section 2.06), redemption, registration of transfer or exchange, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation pursuant to Section 2.13 of the Original Indenture. All such Notes delivered to the Trustee shall be cancelled promptly by the Trustee. No Notes shall be authenticated in exchange for any Notes cancelled hereunder or under the Original Indenture.

Section 2.05. Notice of Defaults. The Company shall deliver to the Trustee, at its Corporate Trust Office, in accordance with Section 13.02 of the Original Indenture, within 30 calendar days after the occurrence thereof, an Officer’s Certificate containing notice of any events that would constitute Defaults or Events of Defaults, the status thereof and what action the Company is taking or proposes to take in respect thereof, which notice shall make express reference to the Company, the Indenture and the Notes.

Section 2.06. Additional Notes; Repurchases. The Company may, without the consent of the Holders of the Notes and notwithstanding Section 2.01, reopen this Supplemental Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 13.05 of the Original Indenture, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased to be surrendered to the Trustee for cancellation, and such Notes shall no longer be considered Outstanding under the Indenture upon the repurchase thereof.

ARTICLE VI

Consolidation, Merger, Sale, Conveyance and Lease

Section 6.01. Applicability of Article 5 of the Original Indenture. Article 5 of the Original Indenture shall not apply to the Notes. The provisions set forth in this Article VI shall, with respect to the Notes, supersede in their entirety Article 5 of the Original Indenture, and all references in the Original Indenture to Article 5 thereof shall, with respect to the Notes, be deemed to be references to this Article VI.

Section 6.02. Company May Consolidate, etc. on Certain Terms. Subject to the provisions of Section 6.03, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its assets to, another Person, unless:

(a) the resulting, surviving or transferee Person (if not the Company) (the “Successor Company”), shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the Notes and the Indenture; and

(b) immediately after giving effect to the transaction, no Default or Event of Default shall have occurred and be continuing.

For purposes of this Section 6.02, the sale, conveyance, transfer or lease of all or substantially all of the assets of one or more Subsidiaries of the Company to another Person that is not a Subsidiary of the Company, which assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the assets of the Company to another Person.

Section 6.03. Successor Company to be Substituted. Upon any such consolidation, merger or sale, conveyance, transfer or lease, the Successor Company (if not the Company) shall succeed to, and may exercise every right and power of, the Company under the Indenture with the same effect as if such successor had been named as the Company herein; and thereafter the Company shall be discharged from its obligations under the Notes and this Indenture, except in the case of any such lease.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Section 6.04. Opinion of Counsel to be Given to Trustee. The Company shall not enter into any consolidation, merger, sale, conveyance, transfer or lease subject to Section 6.02 unless the Trustee shall have received an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article VI.

ARTICLE VII

Optional Redemption

Section 7.01. Applicability of Article 3 of the Original Indenture. Article 3 of the Original Indenture shall not apply to the Notes. Instead, the provisions set forth in this Article VII shall, with respect to the Notes, supersede in its entirety Article 3 of the Original Indenture and all references in the Original Indenture to Article 3 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article VII and the provisions set forth in this Article VII.

Section 7.02. Right to Redeem. The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. The Company has the option to redeem the Notes (an “Optional Redemption”):

(a) prior to the Par Call Date, at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points less (b) interest accrued to the Redemption Date, and

(ii) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date. The Company’s actions and determinations in determining the Redemption Price will be conclusive and binding for all purposes, absent manifest error.

(b) on or after the Par Call Date, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

Section 7.03. Redemption Date; Notice of Optional Redemption; Selection of Notes.

(a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any part of the Notes pursuant to Section 7.02, it shall fix a date for redemption (each, a “Redemption Date”) and it or, at its written request received by the Trustee at least five Business Days (or such shorter period of time as may be acceptable to the Trustee) before notice of redemption is required to be transmitted to Holders in the manner herein provided, the Trustee, in the name of and at the expense of the Company, shall mail or electronically deliver, or cause to be mailed or electronically delivered, a notice of such Optional Redemption (a “Redemption Notice”) not less than 10 nor more than 60 calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the Security Register; provided, however, that, if the Company shall give such notice, it shall also give written notice of the Redemption Date to the Trustee.

(b) The Redemption Notice, if transmitted in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that interest on the Notes, if any, shall cease to accrue on and after the Redemption Date if the Redemption Price is paid on such date;

(iv) the place or places where such Notes are to be surrendered for payment of the Redemption Price;

(v) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes, and that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; and

(vi) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued.

Subject to Section 7.03(e), a Redemption Notice shall be irrevocable.

(d) If fewer than all of the outstanding Notes are to be redeemed and the Notes are in the form of Global Notes, the Depository will select the Notes to be redeemed and the redemption will be done on a pro-rata pass-through distribution basis in accordance with the policies and procedures of the Depository. If fewer than all of the outstanding Notes are to be redeemed and the Notes are in the form of Physical Notes, the Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of $2,000 or integral multiples of $1,000 in excess thereof) on a pro rata basis. No Notes of a principal amount of $2,000 or less will be redeemed in part.

(e) Any redemption of the Notes may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, consummation of any sale of equity interests in the Company, incurrence of Indebtedness, or acquisition, merger or consolidation. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall describe such conditions and state that, in the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be rescinded (by the Company in its sole discretion) in the event that any or all such conditions shall not have been satisfied (or waived by the Company in its sole discretion) by the Redemption Date, or by the Redemption Date so delayed.

Section 7.04. Payment of Notes Called for Redemption.

(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 7.03, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price.

(b) Subject to the satisfaction of the condition or conditions precedent, no later than 11:00 a.m., New York City time, on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.07 of the Original Indenture an amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made promptly after the later of:

(i) the Redemption Date for such Notes; and

(ii) the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by this Section 7.04.

(c) Upon surrender of a Note that is to be redeemed in part only pursuant to Section 7.02, the Company shall execute and upon receipt of an Authentication Order, the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unredeemed portion of the Note surrendered, without payment of any service charge.

ENACT HOLDINGS, INC.

6.250% Senior Notes due 2029

This Note is one of a duly authorized issue of Securities of the Company, designated as its 6.250% Senior Notes due 2029 (the “Notes”), limited to the aggregate principal amount of $750,000,000, all issued or to be issued under and pursuant to the Senior Indenture dated as of May 28, 2024 (the “Original Indenture”), as amended and supplemented by the First Supplemental Indenture dated as of May 28, 2024 (herein called the “Supplemental Indenture”; the Original Indenture, as amended and supplemented by the Supplemental Indenture, and as it may be further amended or supplemented from time to time, the “Indenture”), by and between the Company and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”) to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties, indemnities and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. In the case of an Event of Default specified in Section 6.01(e) or Section 6.01(f) of the Original Indenture, the principal of, and accrued and unpaid interest, if any, on, all outstanding Securities shall automatically become due and payable immediately.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Redemption Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

Subject to the terms and conditions of the Indenture, no reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, the Redemption Price, if applicable, of, and accrued and unpaid interest on this Note at the place, at the respective times, in the amounts and, if applicable, in the lawful money herein prescribed.

The Notes are issuable in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

The Notes shall be redeemable at the Company’s option in accordance with the terms and conditions specified in the Indenture.

Terms used in this Note and defined in the Indenture are used herein as therein defined.
