MISCELLANEOUS

Section 4.01.      General References . Unless otherwise specified or unless the context otherwise requires, (i) all references in this Supplemental Indenture to Articles and Sections refer to the corresponding Articles and Sections of this Supplemental Indenture and (ii) the terms “herein,” “hereof,” “hereunder” and any other word of similar import refers to this Supplemental Indenture.

Section 4.02.      Effectiveness of Supplemental Indenture . Upon the effectiveness of this Supplemental Indenture, the Indenture shall be and be deemed to be modified and amended in accordance herewith and the respective rights, limitations of rights, obligations, duties and immunities under the Indenture of the Trustee, the Issuers and the Holders affected thereby shall hereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of this Supplemental Indenture shall be and be deemed to be part of the terms and conditions of the Indenture for any and all purposes.

Section 4.03.      Indenture Remains in Full Force and Effect . Except as amended and supplemented hereby, all provisions in the Indenture shall remain in full force and effect and are in all respects ratified and confirmed. Notwithstanding anything to the contrary herein, as to the Holders of the Outstanding Notes, the provisions of this Supplemental Indenture are intended to either (x) provide additional rights or benefits to such Holders or (y) not adversely affect the legal rights of such Holders, and this Supplemental Indenture shall be construed and enforced to give effect to the foregoing.

Section 4.04.      Supplemental Indenture Controls . If there is any conflict or inconsistency between the Indenture and this Supplemental Indenture, the provisions of this Supplemental Indenture shall control.

Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.  Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

Section 4.08.      Severability . If any provision of this Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby, and no Holder of the Outstanding Notes shall have any claim therefor against any party hereto.

Section 4.09.      Governing Law . THE LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE.

Section 4.10.      Counterparts . The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.
