Details of the Tender Offer

The Tender Offer will expire at 5:00 p.m., New York City time, on November 21, 2025, unless extended or earlier terminated by the Company in its sole discretion (such time and date, as the same may be extended, the "Expiration Time"). In order for Holders to be eligible to receive the Total Consideration (as defined below) for their Notes, such Holders must validly tender (and not validly withdraw) such Notes at or prior to 5:00 p.m., New York City time, on November 5, 2025, unless extended by the Company in its sole discretion (such time and date, as the same may be extended, the "Early Tender Time"). Holders that tender Notes after the Early Tender Time but at or prior to the Expiration Time will only be eligible to receive the Tender Offer Consideration (as defined below), which does not include the Early Tender Payment (as defined below).

The consideration for each U.S.$1,000 principal amount of Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time and accepted for purchase pursuant to the Tender Offer (the "Total Consideration") will be U.S.$1,000. The Total Consideration includes an early tender payment (the "Early Tender Payment") equal to U.S.$50 per U.S.$1,000 principal amount of Notes, which is payable in respect of Notes validly tendered (and not validly withdrawn) and accepted for purchase pursuant to the Tender Offer. Holders who tender (and do not validly withdraw) their Notes after the Early Tender Time but at or prior to the Expiration Time will be eligible to receive U.S.$950 per U.S.$1,000 principal amount of Notes, which is (i) the Total Consideration minus (ii) the Early Tender Payment (the "Tender Offer Consideration").

In addition, Holders whose Notes are accepted for purchase will also receive accrued and unpaid interest on such Notes from the last interest payment date up to, but not including, the applicable Settlement Date (as defined below) for the Notes accepted for purchase (the "Accrued Interest"). The Company will only accept for purchase Notes up to the Maximum Amount.

The Company's obligation to accept for purchase, and to pay for, any Notes validly tendered and not validly withdrawn pursuant to the Tender Offer is conditioned upon the satisfaction or, when applicable, waiver of certain customary conditions, as further described in the Offer to Purchase.

On any day that is at least three business days following the Early Tender Time and before the Expiration Time, the Company will have the right, but not the obligation, to accept for purchase any Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time (the "Early Settlement Date"), subject to the Maximum Amount and proration. The Early Settlement Date with respect to the Tender Offer will be determined at the Company's option, subject to all conditions to the Tender Offer having been either satisfied or waived by the Company.

Regardless of whether the Company exercises its option to have an Early Settlement Date with respect to the Tender Offer, the Company will purchase any remaining Notes that have been validly tendered (and not validly withdrawn) at or prior to the Expiration Time and that the Company chooses to accept for purchase, subject to all conditions to the Tender Offer having been either satisfied or waived by the Company, within two business days following the Expiration Time or as promptly as practicable thereafter (the "Final Settlement Date"; the Final Settlement Date and the Early Settlement Date, each being referred to as a "Settlement Date"), subject to the Maximum Amount and proration.

If the purchase of all Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time would cause the Company to accept for purchase an aggregate principal amount of Notes in excess of the Maximum Amount, then the Tender Offer will be oversubscribed at the Early Tender Time and, assuming satisfaction or waiver of the conditions to the Tender Offer, the Company will purchase Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time and accepted for purchase on a prorated basis according to the principal amount of such Notes, such that the Company purchases an aggregate principal amount of Notes that does not exceed the Maximum Amount. Accordingly, if the Maximum Amount is reached in respect of tenders of Notes made at or prior to the Early Tender Time, no Notes tendered after the Early Tender Time will be accepted for purchase.

If all Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time would not cause the Company to accept for purchase an aggregate principal amount of Notes equal to or in excess of the Maximum Amount, assuming satisfaction or waiver of the conditions of the Tender Offer, the Company will purchase on the Final Settlement Date Notes validly tendered (and not validly withdrawn) after the Early Tender Time but at or prior to the Expiration Time and accepted for purchase, subject to the Maximum Amount and proration. If the purchase of such Notes would cause the Company to accept for purchase an aggregate principal amount of Notes in excess of the Maximum Amount, then the Tender Offer will be oversubscribed at the Expiration Time and, assuming satisfaction or waiver of the conditions to the Tender Offer, the Company will purchase on the Final Settlement Date Notes validly tendered (and not validly withdrawn) after the Early Tender Time but at or prior to the Expiration Time and accepted for purchase on a prorated basis according to the principal amount of such Notes, such that the Company purchases the maximum aggregate principal amount of Notes that does not exceed the Maximum Amount; provided that Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time will have priority in acceptance over Notes validly tendered after the Early Tender Time.

Tendered Notes may be withdrawn in accordance with the terms of the Tender Offer prior to 5:00 p.m., New York City time, on November 5, 2025, unless extended by the Company in its sole discretion (such time and date, as the same may be extended, the "Withdrawal Deadline"), but not thereafter. The Early Tender Time or Expiration Time may be extended independently of the Withdrawal Deadline.

In addition, to the extent legally permitted to do so, the Company reserves the right, in its sole discretion, at any time to (i) waive any condition to the Tender Offer, (ii) amend any of the terms of the Tender Offer, (iii) terminate the Tender Offer, (iv) increase or decrease the Maximum Amount, (v) extend the Withdrawal Deadline, (vi) extend or amend the Early Tender Time or the Expiration Time, or (vii) modify the Tender Offer Consideration or the Early Tender Payment, in each case (other than clause (v)) without extending the Withdrawal Deadline or otherwise reinstating withdrawal rights of Holders, subject to applicable law.

Tendering Holders who wish to tender their Notes for cash and also subscribe for the New Notes should quote a unique identifier code ("Unique Identifier Code"), which can be obtained by contacting the Dealer Managers (identified below), in their ATOP instruction (as defined in the Offer to Purchase). A Unique Identifier Code is not required for a Holder to tender its Notes, but if a tendering Holder wishes to subscribe for the New Notes, such holder should obtain and quote a Unique Identifier Code in its ATOP instruction. The Company will review tender instructions received on or prior to the Expiration Time and may give priority to those investors tendering with Unique Identifier Codes in connection with the allocation of New Notes. However, no assurances can be given that any Holder that tenders Notes will be given an allocation of New Notes at the levels it may subscribe for, or at all.
