Optional Deferral of Interest Payments:
The Issuer may elect at one or more times to defer payment of all (but not less than all) of the interest accrued on the Notes for one or more consecutive interest periods or interest payment dates. The Issuer may not defer payment of such interest beyond the Scheduled Maturity Date, any earlier accelerated maturity date arising from an Event of Default (which, under the Indenture, is limited to certain payment defaults and events of bankruptcy, insolvency or receivership involving the Issuer) or any other earlier redemption of the Notes. See “Description of the Notes—Interest—Optional Deferral of Interest Payments” in the Preliminary Prospectus Supplement. Any such accrued interest, the payment of which is so deferred, so long as such interest remains unpaid, will constitute Arrears of Interest and will be subject to the provisions described under “Description of the Notes—Interest—Arrears of Interest” in the Preliminary Prospectus Supplement.
Mandatory Deferral of Interest Payments and Arrears of Interest:
If, as of any Interest Payment Date, a Mandatory Deferral Event has occurred and is continuing, the Issuer shall be required to defer payment of all (and not less than all) of the interest accrued on the Notes as of such Interest Payment Date. See “Description of the Notes—Interest—Mandatory Deferral of Interest Payments” in the Preliminary Prospectus Supplement. Any such accrued interest, the payment of which is so deferred, so long as such interest remains unpaid, will constitute Arrears of Interest and will be subject to the provisions described under “Description of the Notes—Interest—Arrears of Interest” in the Preliminary Prospectus Supplement.



Redemption Provisions:
Subject to the provisions set forth under “Conditions to Redemption and Repayment” below, the Notes will be redeemable, at the Issuer’s sole option, in whole or in part, at any time that is not during a Par Call Period, at a redemption price, as calculated by the Issuer, equal to the greater of: (a) 100% of the principal amount of the Notes to be redeemed; and (b) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes (not including any portion of such payments of interest accrued as of such Redemption Date) that would be due if the Notes matured on the next Par Call Date, discounted to such Redemption Date on a semi-annual basis (assuming a 360-day year comprising twelve 30-day months) at the Treasury Rate, plus 50 basis points; plus, in each case, accrued and unpaid interest on such Notes to, but excluding, such Redemption Date.
At any time during a Par Call Period, subject to the provisions set forth under “Conditions to Redemption and Repayment” below, the Notes will be redeemable, at the Issuer’s sole discretion, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, such Redemption Date. See “Description of the Notes—Redemption—Optional Redemption” in the Preliminary Prospectus Supplement.
A “Par Call Date” means December 15 of each year preceding a year in which a Reset Date will occur.
A “Par Call Period” means the six month period beginning on, and including, each Par Call Date and concluding on, and including, the next Reset Date.
In addition, subject to the provisions set forth under “Conditions to Redemption and Repayment” below, the Notes will be redeemable, at the Issuer’s sole option, in whole but not in part, at any time, (i) (a) within 90 days of the date on which the Issuer has reasonably determined that a Capital Disqualification Event has occurred or (b) after the occurrence of a Tax Event, in each case, at a redemption price equal to 100% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, on such Notes to, but excluding, such Redemption Date; or (ii) within 90 days after the occurrence of a Rating Agency Event at a redemption price equal to 102% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, on such Notes to, but excluding, such Redemption Date. See “Description of the Notes—Redemption—Optional Redemption upon a Capital Disqualification Event,” “—Optional Redemption upon a Rating Agency Event” and “—Optional Redemption upon a Tax Event” in the Preliminary Prospectus Supplement.



Conditions to Redemption and Repayment:
Notwithstanding anything to the contrary set forth herein, (i) prior to June 15, 2030, the Notes may be redeemed only with BMA Approval (provided that such BMA Approval would be required at such time in order for the Notes to qualify as Tier 2 Capital), and (ii) the Notes may not be redeemed at any time, including on the Scheduled Maturity Date or the Final Maturity Date, as may be applicable, if the Enhanced Capital Requirement would be breached immediately before or after giving effect to the redemption or repayment of such Notes; unless, in the case of each of (i) and (ii), the Issuer or another member of the Insurance Group replaces the capital represented by the Notes to be redeemed or repaid with capital having equal or better capital treatment as the Notes under the Group Rules (collectively, the “BMA Redemption Requirements”). See “Description of the Notes—Conditions to Redemption and Repayment” in the Preliminary Prospectus Supplement.
Variation and Substitution:
If a Capital Disqualification Event, Rating Agency Event or Tax Event occurs, the Issuer may, at its sole option, as an alternative to redemption of the Notes, at any time, without the consent of any Holder of the Notes, vary any term or condition of the Notes or substitute all (but not less than all) of the Notes for other notes, so that the varied Notes or the substituted notes, as the case may be, constitute Qualifying Equivalent Securities. See “Description of the Notes—Variation and Substitution” in the Preliminary Prospectus Supplement.
Further Issuances:The Issuer may, without notice to, and without the consent of, the holders of the Notes, issue an unlimited principal amount of additional notes having identical terms as the Notes offered hereby other than issue date, issue price and the first interest payment date and which will be deemed to be in the same series as the Notes offered hereby.

**It is expected that delivery of the Notes will be made against payment therefor on or about June 13, 2025, which will be the fourth business day following the date of pricing of the Notes (such settlement cycle being herein referred to as “T+3”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to one business day preceding the closing date will be required, by virtue of the fact that the notes initially will settle T+3, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes who wish to trade Notes prior to the first business day before settlement should consult their own advisor.
