AMENDMENTS, SUPPLEMENTS AND WAIVERS
Section 12.01. Without Consent of Holders.
The Company, when authorized by a resolution of the Board of Directors, and the Trustee may amend or supplement the Indenture or the Securities without notice to or consent of any Holder:
(a) to comply with Section 5.11 and 8.01;
(b) to cure any ambiguity, or correct any defect or inconsistency; provided that any amendment or supplement to cure any ambiguity or correct any defect or inconsistency in the Indenture or the Securities that is made solely to conform the provisions of the Indenture and the Securities to the descriptions thereof contained in the offering memorandum relating to the Securities dated April 9, 2008, shall be deemed not to adversely affect the rights of any Holder;
(c) to make any other change that does not adversely affect the rights of any Holder;
(d) to comply with the provisions of the TIA;
(e) to add to the covenants of the Company for the equal and ratable benefit of the Holders or to surrender any right, power or option conferred upon the Company;
(f) to appoint a successor Trustee; or
(g) to provide for the issuance of Additional Securities as permitted by Section 2.16, which will have terms substantially identical to the other outstanding Securities except as specified in Section 2.16, and which will be treated, together with any other outstanding Securities, as a single issue of securities.
Section 12.02. With Consent of Holders.
The Company and the Trustee may amend or supplement the Securities or this Indenture with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. The Holders of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any provision of the Securities or this Indenture without notice to any Holder. However, notwithstanding the foregoing but subject to Section 12.04, without the written consent of each Holder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 9.04, may not:
(a) change the stated maturity of the principal of, or the date any installment of interest (including any Additional Interest) is due on, any Security;
(b) reduce the principal amount of or interest (including any Additional Interest) on, any Security;
(c) reduce the amount of principal payable upon acceleration of the maturity of any Security;
(d) change the place or currency of payment of principal of or interest (including any Additional Interest) on, any Security;
(e) impair the right to institute suit for the enforcement of any payment on, or with respect to, any Security;
(f) modify the provisions with respect to the purchase right of Holders pursuant to Article 3 upon a Fundamental Change in a manner adverse to the Holders of Securities;
(g) modify the provisions of this Indenture with respect to conversion of the Securities in a manner adverse to the Holders of Securities;
(h) modify the subordination provisions in Section 6 of this Indenture in a manner adverse to the Holders of Securities;
(i) reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a modification or amendment; and
(j) modify any of the provisions of this Section or Section 9.04, except to increase any such percentage or to provide that certain provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Security affected thereby.
It shall not be necessary for the consent of the Holders under this Section 12.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.
After an amendment, supplement or waiver under this Section 12.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.
Section 12.03. Compliance with Trust Indenture Act.
Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as applicable to indentures qualified thereunder at the date of such amendment or supplement.
Section 12.04. Revocation and Effect of Consents.
Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holders Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective.
After an amendment, supplement or waiver becomes effective, it shall bind every applicable Holder, unless it makes a change described in any of clauses (a) through (j) of Section 12.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holders Security.
Section 12.05. Notation on or Exchange of Securities.
If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.
Section 12.06. Trustee to Sign Amendments, etc.
The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 12 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be provided with, and, subject to Section 10.01, shall be fully protected in relying upon, an Officers Certificate (accompanied by a resolution of the Board of Directors of the Company) and an Opinion of Counsel in accordance with Section 13.04 hereof, each stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplement indenture until the Board of Directors approves it.
Section 12.07. Effect of Supplemental Indentures.
Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.
