(c) In addition, the Company may, upon giving not less than 30 days nor more than 60 days’ notice to (i) the Trustee and (ii) Holders of the Notes, as the case may be (which notice shall be irrevocable), redeem the Notes at any time from or after April 8, 2030, in whole or in part, at a redemption amount equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

Section 2.05 Repurchase Upon Triggering Event. The following additional covenant shall apply with respect to the Notes so long as any of the Notes remain outstanding:

(a) If a Triggering Event occurs, unless the Company has exercised its right to redeem all of the Notes pursuant to Section 2.02 hereof or Section 4.07 of the Base Indenture, the Company shall make an offer to repurchase all or, at the Holder’s option, any part (equal to US$200,000 or multiples of US$1,000 in excess thereof) of each Holder’s Notes pursuant to the offer described below (the “Triggering Event Offer”), at a purchase price in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of purchase (the “Triggering Event Payment”) (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). Within 30 days following a Triggering Event, unless the Company has exercised its right to redeem all of the Notes pursuant to Section 2.02 hereof or Section 4.07 of the Base Indenture, the Company will deliver a notice of such Triggering Event Offer to each Holder or otherwise give notice in accordance with the applicable procedures of DTC, with a copy to the Trustee, stating:

(i) that a Triggering Event Offer is being made pursuant to this Section 2.05, including a description of the transaction or transactions that constitute the Triggering Event, and that all Notes properly tendered pursuant to such Triggering Event Offer will be accepted for purchase by the Company at a purchase price in cash equal to 101% of the aggregate principal amount of such Notes plus accrued and unpaid interest, if any, on such Notes to, but not including, the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date);

(ii) that the purchase date shall be no earlier than 30 days and no later than 60 days from the date such notice is delivered) (the “Triggering Event Payment Date”);

(iii) that Notes must be tendered in amounts of US$200,000 or multiples of US$1,000 in excess thereof, and any Note not properly tendered will remain outstanding and continue to accrue interest;

(iv) that, unless the Company defaults in the payment of the Triggering Event Payment, any Note accepted for payment pursuant to the Triggering Event Offer will cease to accrue interest on and after the Triggering Event Payment Date;

(v) that Holders electing to have any Notes purchased pursuant to a Triggering Event Offer will be required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Triggering Event Payment Date;

(vi) that Holders shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes; provided that the Paying Agent receives at the address specified in the notice, not later than the close of business on the 30th day following the date of the Triggering Event notice, a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

(vii) that if a Holder is tendering less than all of its Notes, such Holder will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to US$200,000 or an integral multiple of US$1,000 in excess thereof); and

(viii) the other instructions, as determined by the Company consistent with this Section 2.05, that a Holder must follow.

The notice, if sent in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. If (A) the notice is sent in a manner herein provided and (B) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect.

(b) On the Triggering Event Payment Date, the Company will, to the extent lawful:

(i) accept for payment all Notes or portions of Notes (of US$200,000 or multiples of US$1,000 in excess thereof) properly tendered pursuant to the Triggering Event Offer;

(ii) deposit with the Paying Agent, one Business Day prior to the Triggering Event Payment Date, an amount equal to the Triggering Event Payment in respect of all Notes or portions of Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee for cancellation the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company in accordance with the terms of this Section 2.05.

(c) The Paying Agent shall promptly deliver, to each Holder who properly tendered Notes, the purchase price for such Notes properly tendered, and the Trustee shall promptly authenticate and deliver (or cause to be transferred by book-entry) to each such Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of US$200,000 or a multiple of US$1,000 in excess thereof.

(d) If the Triggering Event Payment Date is on or after the relevant Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest to the Triggering Event Payment Date shall be paid on such Interest Payment Date to the Person in whose name a Note is registered at the close of business on such Record Date.

(e) The Company will not be required to make a Triggering Event Offer upon a Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or defaults its offer, the Company will be required to make a Triggering Event Offer treating the date of such termination or default as though it were the date of the Triggering Event.

(f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, to the extent applicable, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Triggering Event. To the extent that the provision of any such securities laws or regulations conflicts with the Triggering Event Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Triggering Event Offer provisions of the Notes by virtue of any such conflict.

Section 2.06 Covenant Defeasance. Upon the Company’s exercise under Section 12.03(a) of the Base Indenture of the option applicable to Section 12.03(c) thereof, the Company shall, subject to the satisfaction of the conditions set forth in Section 12.03(d) thereof, be released from its obligations under the covenants contained in Section 6.04 and Section 6.06 thereof and from its obligations under the covenants contained in Section 2.04 and Section 2.05 of this Second Supplemental Indenture, on and after the date the conditions set forth in Section 12.03(d) thereof are satisfied.

“to conform the text of this Indenture or any series of the Securities to any provision of the section entitled “Description of Debt Securities” in the Prospectus or of the section entitled “Description of the Notes” in the Prospectus Supplement to the extent that such provision in the Prospectus or the Prospectus Supplement, as the case may be, was intended to be a verbatim recitation of a provision of this Indenture or such series of the Securities as evidenced by an Officers’ Certificate;”
