| Optional Interest Deferral: |
The terms of each series of Notes will provide that so long as no event of default (as defined in the Preliminary Prospectus) with respect to the Notes of such series has occurred and is continuing, we may, at our option, defer interest payments on such series of Notes, from time to time, for one or more deferral periods of up to 20 consecutive semi-annual Interest Payment Periods (as defined in the Preliminary Prospectus) applicable to such series of Notes each (each such deferral period, commencing on the interest payment date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the final maturity date of the Notes of such series or end on a day other than the day immediately preceding an interest payment date applicable to such series of Notes. In other words, with respect to each series of Notes, we may declare at our discretion up to a ten-year interest payment moratorium and may choose to do that on one or more occasions. No interest will be due or payable on the Notes of such series during an Optional Deferral Period, unless we elect, at our option, to redeem any Notes of such series on any redemption date during such Optional Deferral Period, in which case all accrued and unpaid interest on the Notes of such series to be redeemed to, but excluding, such redemption date will be due and payable on such redemption date, or unless the principal of and interest on the Notes of such series shall have been declared due and payable as the result of an event of default with respect to the Notes of such series, in which case, all accrued and unpaid interest, including, to the extent permitted by applicable law, any interest on the deferred interest (“compound interest”), on the Notes of such series shall become due and payable. We may elect, at our option, to extend the length of any Optional Deferral Period that is shorter than 20 consecutive semi-annual Interest Payment Periods (so long as the entire Optional Deferral Period does not exceed 20 consecutive semi-annual Interest Payment Periods or extend beyond the final maturity date of the Notes of such series) and to shorten the length of any Optional Deferral Period. With respect to each series of Notes, we cannot begin a new Optional Deferral Period until we have paid all accrued and unpaid interest on the Notes of such series from any previous Optional Deferral Periods. During any Optional Deferral Period applicable to a series of Notes, interest on the applicable series of Notes will continue to accrue at the then-applicable interest rate on the Notes of such series (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes of such series). In addition, during any Optional Deferral Period, interest on the deferred interest will accrue at the then-applicable interest rate on the Notes with respect to the Notes of either series (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes of such series), compounded semi-annually, to the extent permitted by applicable law. |
| Certain Restrictions During an Optional Deferral Period: | During any Optional Deferral Period, with respect to the Notes of either series, we (and our subsidiaries, as applicable) may not do any of the following (subject to certain exceptions): (i) declare or pay dividends or distributions on any of our capital stock, (ii) redeem, purchase, acquire or make a liquidation payment with respect to any of our capital stock, (iii) pay any principal, interest or premium on, or repay, repurchase or redeem, any of our indebtedness that ranks equally with or junior to the Notes of such series in right of payment, or (iv) make any payments with respect to any guarantees by us of any indebtedness if such guarantees rank equally with or junior to the Notes of such series in right of payment. |
| Optional Redemption: |
The terms of each series of Notes will provide that at our option, we may redeem some or all of the Notes of such series before their maturity, as follows:
· in whole or from time to time in part, (i) on any day in the period commencing on the date falling 90 days prior to the First Reset Date (as defined in the Preliminary Prospectus) applicable to the Notes of such series and ending on (and including) such First Reset Date and (ii) after such First Reset Date, on any applicable interest payment date, in each case at a redemption price in cash equal to 100% of the principal amount of the Notes of such series to be redeemed, plus, subject to the terms described in the first paragraph under “Description of the notes—Redemption—Redemption Procedures; Cancellation of Redemption” in the Preliminary Prospectus, accrued and unpaid interest on the Notes of such series to be redeemed to, but excluding, such redemption date;
· in whole, but not in part, at any time within 120 days after the occurrence of a Tax Event (as defined in “Description of the notes—Redemption—Redemption Following a Tax Event” in the Preliminary Prospectus) at a redemption price in cash equal to 100% of the principal amount of the Notes of such series to be redeemed, plus, subject to the terms described in the first paragraph under “Description of the notes—Redemption—Redemption Procedures; Cancellation of Redemption” in the Preliminary Prospectus, accrued and unpaid interest on the Notes of such series to be redeemed to, but excluding, such redemption date; and
· in whole, but not in part, at any time during the continuance of and, in any event, within 120 days after the occurrence of, a Rating Agency Event (as defined in the Preliminary Prospectus) at a redemption price in cash equal to 102% of the principal amount of the Notes of such series to be redeemed, plus, subject to certain terms accrued and unpaid interest on the Notes of such series to be redeemed to, but excluding, such redemption date. |

Delivery of the notes is expected to be made against payment therefor on or about September 14, 2026, which is the third business day following the date of pricing of the notes (such settlement being referred to as “T+3”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, 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 the notes on any date prior to the first business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.
