(7) an event occurs and is continuing as a result of which the offering document for the offer and sale of Qualifying Securities would, in the Issuer’s reasonable judgment, contain an untrue statement of a material fact or omit to state a material fact required to be stated in that offering document or necessary to make the statements in that offering document not misleading and either (a) the disclosure of that event at such time, in the Issuer’s reasonable judgment, is not otherwise required by law and would have an adverse effect on the Issuer’s business in any material respect, (b) the disclosure relates to a previously undisclosed proposed or pending material business transaction, the disclosure of which would impede, delay or otherwise negatively affect the Issuer’s ability to consummate that transaction or (c) the event relates to a previously undisclosed material (re)insurance loss and the disclosure of that event

at such time, in the Issuer’s reasonable judgment, is impeded by the current nature of such event and the extent of losses remain under consideration by the Issuer’s management pending further information from brokers, cedants or insureds; provided that no single suspension period described in this clause (7) shall exceed 90 consecutive days and multiple suspension periods described in this clause (7) shall not exceed an aggregate of 90 days in any 180-day period; or

(8) the Issuer reasonably believes that the offering document for the offer and the sale of Qualifying Securities would not be in compliance with a rule or regulation of the Commission or any other securities regulatory authority or exchange to which the Issuer is subject (for reasons other than those described in the immediately preceding clause (7)) and the Issuer is unable to comply with such rule or regulation or such compliance is unduly burdensome; provided that no single suspension period described in this clause (8) shall exceed 90 consecutive days and multiple suspension periods described in this clause (8) shall not exceed an aggregate of 90 days in any 180-day period.

“Qualifying Securities” means any securities (other than the Issuer’s common shares, rights to purchase the Issuer’s common shares and securities convertible into or exchangeable for the Issuer’s common shares, such as preference shares that are convertible into the Issuer’s common shares) having equal or better capital treatment as the capital represented by the Notes under the Group Rules.

“Reference Treasury Dealer” means (a) each of Barclays Capital Inc., HSBC Securities (USA) Inc. and Xxxxx Fargo Securities, LLC or their affiliates that are primary U.S. government securities dealers and their respective successors, unless any of them ceases to be a primary U.S. government securities dealer in New York City (a “Primary Treasury Dealer”), in which case the Issuer shall substitute another Primary Treasury Dealer and (b) two other Primary Treasury Dealers that the Issuer selects.

the Indenture and such requirement cannot be avoided by the use of reasonable measures (consistent with practices and interpretations generally followed or in effect at the time such measures could be taken) then available.

“Tier 3 Capital” means “Tier 3 Ancillary Capital” as set out in the Group Supervision Rules (or, if the Group Supervision Rules are amended so as to no longer refer to Tier 3 Ancillary Capital in this respect, the nearest corresponding concept (if any) under the Group Supervision Rules, as amended).

ARTICLE II

General Terms and Conditions of the Notes

SECTION 2.1. Designation and Principal Amount. There is hereby authorized and established a series of Securities under the Indenture, designated as the “3.100% Senior Notes due 2031,” which is not limited in aggregate principal amount. The aggregate principal amount of the Notes to be issued as of the date hereof shall be $500,000,000.

SECTION 2.2. Further Issues. So long as no Event of Default shall have occurred and be continuing with respect to the Notes at the time of such issuance, the Issuer may from time to time, without the consent of the Holders of the Notes, issue additional Notes. Any such additional Notes will have the same interest rate, maturity date and other terms as the Notes, but may have a different issue date, issue price, initial interest accrual date and initial Interest Payment Date. Any such additional Notes, together with any other Notes previously issued pursuant to this Supplemental Indenture, will constitute a single series of Securities under the Indenture; provided that if any such additional Notes would not be fungible with the outstanding Notes for U.S. federal income tax purposes, the Issuer shall cause such additional Notes to be issued with a separate CUSIP number.

SECTION 2.3. Interest. The Notes will bear interest (computed on the basis of a 360-day year consisting of twelve 30-day months) from August 24, 2021 at the rate of 3.100% per annum, payable semi-annually in arrears; the dates on which such interest shall be payable are March 1 and September 1 (each an “Interest Payment Date”), commencing on March 1, 2022; interest payable on each Interest Payment Date will include interest accrued from August 24, 2021, or from the most recent Interest Payment Date to which interest has been paid or duly provided for; and the record date for the determination of Holders to whom interest is payable on any Interest Payment Date is the close of business on the February 15 or August 15, as the case

may be, immediately preceding the relevant Interest Payment Date, whether or not that day is a Business Day.

SECTION 2.4. Offices for Payments, Etc. Payment of the principal of (and premium, if any) and interest on the Notes will be made at the Corporate Trust Office of the Trustee, or an office or agency maintained by the Issuer for such purpose, in the Borough of Manhattan, The City of New York, in Dollars; provided, however, that at the option of the Issuer payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Securities Register; and provided further, however, that all payments in respect of Notes in the form of global Securities shall be made by wire transfer in same-day funds in accordance with the applicable procedures of the Depositary. In any case where the date of maturity or date of payment of interest on, premium, if any, or principal of any Note or the date fixed for redemption of the Notes is not a Business Day, then the relevant payment need not be made on such date but may be made on the next Business Day with the same force and effect as if made on such date and no interest shall accrue in respect of such amount for the intervening period. The Notes may be presented for registration of transfer and for exchange, and notices to or upon the Issuer in respect of such Notes may be served, at the Corporate Trust Office of the Trustee, or an office or agency maintained by the Issuer for such purpose, in the Borough of Manhattan, The City of New York.

SECTION 2.5. Redemption.

(a) The Issuer may, at its option, subject to the BMA Redemption Requirements, redeem the Notes, at any time or from time to time, either in whole or in part. At any time prior to March 1, 2031 (the date that is six months prior to the Scheduled Maturity Date of the Notes) (the “Par Call Date”), the redemption price to be paid by the Issuer shall equal the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) as determined by the Independent Investment Banker, the sum of the present values of the remaining principal amount and scheduled payments of interest on the Notes to be redeemed (excluding interest accrued to the redemption date and assuming that the Notes mature on the Par Call Date) discounted to the redemption date on a semi-annual basis at the Treasury Rate plus 30 basis points. The redemption price will be calculated assuming a 360-day year consisting of twelve 30-day months. On or after the Par Call Date, the redemption price to be paid by the Issuer shall equal 100% of the principal amount of the Notes to be redeemed.

(b) In addition to the redemption price, the Issuer will pay accrued and unpaid interest, if any, on the Notes to, but excluding, the redemption date.

(c) The Issuer will provide notice of any redemption at least 15 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed, in accordance with the provisions of Section 11.4 and Section 12.2 of the Indenture. Each such notice shall specify the date fixed for redemption, the places of redemption and the redemption price at which such Notes are to be redeemed (or the manner of calculating such redemption price if not then determinable), and shall state that payment of the redemption price of such Notes or portion thereof to be redeemed will be made on surrender of such Notes at such places of redemption.

(d) Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions of the Notes called for redemption.

(e) If fewer than all of the Notes are to be redeemed at any time, the particular Notes to be redeemed shall be selected, from the outstanding Notes not previously called for

redemption, in accordance with the applicable rules and procedures of the Depositary, in the case of Notes in the form of global Securities, or, otherwise, by the Trustee by lot.

(f) If any Note is to be redeemed in part only, the notice of redemption that relates to that Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note will be issued (or transferred through a book-entry system) in the name of the Holder thereof upon cancellation of the original Note. No Notes of $2,000 or less will be redeemed in part.

SECTION 2.6. Mandatory Redemption. The Issuer is not required to make any mandatory redemption or sinking fund payments with respect to the Notes.

SECTION 2.7. Denominations. The Notes will be issued in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

SECTION 2.8. Global Securities. The Notes will be issued as Registered Securities in the form of one or more permanent global Securities.

SECTION 2.9. Additional Amounts. The provisions of Section 3.11 of the Indenture will apply to the Notes.

SECTION 2.10. Redemption for Tax Purposes. Solely for purposes of the Notes, Section 3.12 of the Indenture is replaced in its entirety with the following: “The Issuer may, at its option, subject to the BMA Redemption Requirements, redeem the Notes, at any time, in whole but not in part, following the occurrence of a Tax Event at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the Notes to, but excluding, the redemption date. If the Issuer elects to redeem the Notes under this provision, the Issuer will give written notice of such election at least 15 days but no more than 60 days before the redemption date to the Trustee and the Holders of the Notes. Interest on the Notes will cease to accrue as of the redemption date unless the Issuer defaults in the payment of the redemption price set forth in this Section 3.12.”

SECTION 2.11. Limitation on Liens on Stock of Significant Subsidiaries. Solely for purposes of the Notes, Section 3.13 of the Indenture is replaced in its entirety with the following: “The Issuer shall not, nor shall it permit any Subsidiary to, create, incur, assume or guarantee or otherwise permit to exist any Indebtedness secured by any Lien, on any shares of Capital Stock of any Significant Subsidiary.”

SECTION 2.12. Supplemental Indentures.

(a) Section 8.1(i) of the Indenture shall not apply to the Notes.

(b) Solely for purposes of the Notes, Section 8.1(iv) of the Indenture is replaced in its entirety with the following: “(iv) to cure any ambiguity or to correct or supplement any provision contained herein or in the Supplemental Indenture which may be defective or inconsistent with any other provision contained herein, in the Supplemental Indenture, or in the prospectus or the prospectus supplement with respect to the Notes or to make any other provisions as the Issuer may deem necessary or desirable with respect to matters or questions arising under this Indenture, provided that no such action shall materially adversely affect the interests of the Holders of the Notes”.

(c) Notwithstanding anything to the contrary in Section 8.2(a) of the Indenture, no supplemental indenture may, without the consent of each Holder of an affected Note and the

BMA, change the stated maturity of, the principal of, or any premium or installment of interest on, or any Additional Amounts with respect to, any of the Notes.

SECTION 2.13. Ranking. The Notes will represent the Issuer’s unsecured obligations and will rank equally with all of the Issuer’s other existing and future unsecured unsubordinated indebtedness. The Notes will rank senior in right of payment to the Issuer’s guarantee of the Junior Subordinated Notes and any future subordinated indebtedness the Issuer incurs. The Notes will be contractually subordinated in right of payment to all obligations of the Issuer’s subsidiaries (other than the Issuer’s finance subsidiary Enstar Finance LLC) including all existing and future policyholder obligations of the Issuer’s subsidiaries.

SECTION 2.14. Appointment of Agents. The Trustee will initially be the paying agent, registrar and custodian for the Notes.

SECTION 2.15. Satisfaction and Discharge; Defeasance. The provisions of Article 10 of the Indenture will apply to the Notes.

SECTION 2.16. Depositary. The Depository Trust Company, a New York corporation, will initially act as Depositary with respect to the Notes.

SECTION 2.17. Conditions to Redemption and Repayment.

(a) In the event that the Notes are not redeemed or repaid as a result of a failure to satisfy the BMA Redemption Requirements, interest on the Notes will continue to accrue and be paid on each Interest Payment Date until the first date on which final payment on the Notes may be made as described in Section 4.1, at which time the Notes will become due and payable, and will be finally repaid at the principal amount of the Notes, together with any accrued and unpaid interest in the manner and subject to the BMA Redemption Requirements.

(b) Notwithstanding any provision of the Notes, this Supplemental Indenture or the Indenture, in the event of non-payment on a scheduled redemption date or the Scheduled Maturity Date resulting from a failure to satisfy the BMA Redemption Requirements, the Notes to be redeemed or repaid will not become due and payable on such date, and such non-payment will constitute neither an Event of Default nor a default of any kind with respect to the Notes, and will not give Holders of the Notes or the trustee any right to accelerate repayment of the Notes or any other remedies pursuant to Article 5 of the Indenture or otherwise.

(c) An Officer’s Certificate relating to the Notes in connection with repayment or any redemption under this Article II certifying that (i) the BMA Redemption Requirements have not been met or would not be met if the Notes were repaid or the applicable redemption payment were made, (ii) the BMA Redemption Requirements have been met and would continue to be met if the Notes were to be repaid or the applicable redemption payment were made or (iii) no such BMA Redemption Requirements apply shall, in the absence of manifest error, be treated and accepted by the Trustee, the Holders and all other interested parties as correct and sufficient evidence thereof and shall be final and binding on such parties. The Trustee shall be entitled to rely conclusively on such Officer’s Certificate without liability to any Person and shall have no duty to ascertain the existence of any such manifest error.

SECTION 2.18. Electronic Authentication. The Notes may be authenticated by the Trustee by the manual, facsimile or electronic signature of one of its authorized signatories.

ARTICLE III

Form of Notes

SECTION 3.1. Form of Notes. The Notes and the Trustee’s certificate of authentication to be endorsed thereon are to be substantially in the form set forth in Exhibit A hereto.

ARTICLE IV

Repayment and Redemption

SECTION 4.1. Repayment at Final Maturity Date.

(a) Unless the Notes are redeemed prior to maturity, the Notes will mature, and the principal amount of the Notes will become payable on the Final Maturity Date, at a price equal to the principal amount thereof, together with accrued and unpaid interest on the Notes to, but excluding, the Final Maturity Date.

For the avoidance of doubt, interest shall continue to accrue and be payable for so long as the principal amount of the Notes remains outstanding. In the event the Scheduled Maturity Date and the Final Maturity Date are not the same, failure to repay the Notes on the Scheduled Maturity Date will constitute neither an Event of Default nor a default of any kind and will not give Holders of the Notes or the Trustee any right to accelerate repayment of the Notes or any other remedies.

(b) If

(1) as of the Solvency Test Date or any date thereafter and including on the Scheduled Maturity Date or the Final Maturity Date, as may be applicable, the Issuer (i) does not have sufficient capital to satisfy the Enhanced Capital Requirement (the “First ECR Condition”) or (ii) would not have sufficient capital to satisfy the Enhanced Capital Requirement after giving effect to the repayment of the Notes (the “Second ECR Condition” and, together with the First ECR Condition, each an “ECR Condition”), the Issuer will be required to promptly begin using Commercially Reasonable Efforts, subject to the existence of a Market Disruption Event, to raise proceeds from the issuance of Qualifying Securities in an amount at least equal to the principal amount of the Notes due to be repaid (the “Replacement Capital Obligation”);

(2) on or after the Solvency Test Date and prior to the Scheduled Maturity Date, the Issuer is unable to satisfy any ECR Condition, the Issuer shall, within ten Business Days of the principal executive officer or the principal financial officer of the Issuer becoming aware of the Issuer’s inability to so satisfy such ECR Condition, notify the Trustee in writing of such inability (and direct the Trustee to transmit such notice to the Holders of the Notes); provided, however, that the Issuer shall provide any such notice no later than the Business Day immediately preceding the Scheduled Maturity Date; and

(3) the Scheduled Maturity Date and Final Maturity Date are not the same, after a Final Maturity Date has been established,

then

(i) the Issuer shall promptly notify the Trustee in writing of such Final Maturity Date (and direct the Trustee to transmit such notice to the Holders of the Notes); and

(ii) if the Issuer will then be unable to satisfy any ECR Condition as of such Final Maturity Date, the Issuer shall, promptly after the principal executive officer or the principal financial officer of the Issuer becomes aware of the Issuer’s inability to so satisfy such ECR Condition, notify the Trustee in writing of such inability (and direct the Trustee to transmit such notice to the Holders of the Notes); provided, however, that the Issuer shall provide any such notice no later than the Business Day immediately preceding such Final Maturity Date.

If a successful issuance of Qualifying Securities satisfying the Replacement Capital Obligation occurs after the Solvency Test Date, but prior to the Scheduled Maturity Date or the Final Maturity Date, as may be applicable (an “RCO Satisfying Issuance”), then (a) such RCO Satisfying Issuance will constitute an issuance of replacement capital in satisfaction of the BMA Redemption Requirements for redemptions or repayments occurring prior to or on the Scheduled Maturity Date or the Final Maturity Date, as may be applicable, and (b) the Issuer shall promptly notify the Trustee of such RCO Satisfying Issuance in writing (and direct the Trustee to transmit such notice to the Holders of the Notes). Subject to the prior sentence, the Replacement Capital Obligation will continue to apply until the earliest of (a) an RCO Satisfying Issuance, (b) the BMA Redemption Requirements being satisfied by means other than an RCO Satisfying Issuance; provided that, if the BMA Redemption Requirements cease to be satisfied prior to the Final Maturity Date, the Replacement Capital Obligation will be reinstated or (c) the occurrence of an Event of Default. Accordingly, the Replacement Capital Obligation will cease to apply if the Issuer is able to restore its compliance with the Enhanced Capital Requirement, after giving effect to repayment of the Notes, by a means other than the issuance of Qualifying Securities or with an issuance of Qualifying Securities that is less than the principal amount of the Notes, subject to the reinstatement of the Replacement Capital Obligation as described in the preceding sentence.

The Issuer’s failure to use Commercially Reasonable Efforts to raise sufficient proceeds from the issuance of Qualifying Securities to satisfy the Replacement Capital Obligation, subject to the existence of a Market Disruption Event, shall constitute a breach of a covenant hereunder (a “Replacement Capital Obligation Default”), but it shall not in any case constitute a default or an Event of Default hereunder or give rise to a right of acceleration of payment of the Notes or any other remedy under the terms of the Indenture or the Notes. The sole remedy for a breach of such covenant is for the Trustee (at the direction of the required Holders) or the Holders of at least 25% in aggregate principal amount of the Notes, subject to Section 5.6 of the Indenture, to bring suit for specific performance of the Issuer’s obligations with respect to such covenant to use such Commercially Reasonable Efforts with respect to the Replacement Capital Obligation.

For the avoidance of doubt, the Replacement Capital Obligation will not apply at any time while the Enhanced Capital Requirement is satisfied, and if the Issuer would continue to satisfy the Enhanced Capital Requirement after giving effect to a redemption or repayment of the Notes on the Scheduled Maturity Date or the Final Maturity Date, as may be applicable.

(c) If the Issuer is subject to a Replacement Capital Obligation, the Issuer may provide written certification to the Trustee (and direct the Trustee to transmit such notice to the Holders of the Notes) within ten Business Days of the later of (a) the occurrence of a Market

Disruption Event or (b) the beginning of the period of the Replacement Capital Obligation (if such Market Disruption Event occurred prior to the Replacement Capital Obligation period beginning and is continuing) certifying that a Market Disruption Event has occurred and is continuing. If such notice is provided, the Issuer will be excused from the Issuer’s obligation to use Commercially Reasonable Efforts to issue Qualifying Securities pursuant to the Replacement Capital Obligation for an initial suspension period of 90 consecutive days following such certification. The Issuer may extend a suspension period by providing written certification to the Trustee (and direct the Trustee to transmit such notice to the Holders of the Notes) on or prior to the expiration of such suspension period, certifying that the applicable Market Disruption Event is continuing, in which case, the Issuer’s obligation to use Commercially Reasonable Efforts to issue Qualifying Securities pursuant to the Replacement Capital Obligation will be excused for an additional 60 consecutive days following such further certification. Following the expiration of the applicable suspension period, the Issuer’s obligation to use Commercially Reasonable Efforts to issue Qualifying Securities pursuant to the Replacement Capital Obligation shall be reinstated. The Issuer’s ability to initiate or extend a suspension period in connection with a Market Disruption Event will also be subject to the limits on suspension periods provided for in the definition of Market Disruption Event (if applicable). Notwithstanding the foregoing time limitations as to suspension in connection with a particular Market Disruption Event, the suspension of the Issuer’s obligations pursuant to the foregoing shall not prohibit the further suspension of obligations in connection with, and the Issuer shall be entitled to provide separate notices with respect to, any separate and distinct Market Disruption Event(s). In addition, for the avoidance of doubt, the Issuer shall not be prohibited during any suspension of the requirements to use Commercially Reasonable Efforts during a Market Disruption Event from issuing any Qualifying Securities.

For the avoidance of doubt, subject to Section 6.1 of the Indenture, the Trustee shall have no responsibility to make any determinations or calculations under the Indenture or this Supplemental indenture; nor shall it be charged with monitoring or knowledge of (a) the Replacement Capital Obligation or any terms thereof, which collectively shall be the Issuer’s responsibility, (b) the occurrence or continuation of any Replacement Capital Obligation Default, which shall be made by the Holders of the Notes, (c) whether Commercially Reasonable Efforts have been made, (d) whether the conditions to redemption and repayment have been satisfied, (e) whether the BMA Redemption requirements have been satisfied, (f) whether a Market Disruption Event has occurred, (g) whether the Final Maturity Date has occurred or (h) whether an ECR Condition has been met.

The Issuer shall be obligated to pay Additional Amounts in respect of the Securities of this series in accordance with Section 3.11 of the Base Indenture.

The Securities of this series will represent the Issuer’s unsecured obligations and will rank equally with all of the Issuer’s other existing and future unsecured unsubordinated indebtedness. The Securities of this series will rank senior in right of payment to the Issuer’s guarantee of the Junior Subordinated Notes and any future subordinated indebtedness the Issuer incurs. The Securities of this series will be contractually subordinated in right of payment to all obligations of the Issuer’s subsidiaries (other than the Issuer’s finance subsidiary Enstar Finance LLC) including all existing and future policyholder obligations of the Issuer’s subsidiaries.

The Indenture contains provisions for discharge and defeasance at any time of the entire indebtedness of this Security or certain covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

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.
