The Applicable Securities are hereby amended to delete or modify all provisions inconsistent with the amendments to the Indenture effected by this Third Supplemental Indenture, and each global Security shall be deemed supplemented, modified and amended in such manner as necessary to make the terms of such global Security consistent with the terms of the Indenture, as amended by this Third Supplemental Indenture.  To the extent of any conflict between the terms of each such global Security and the terms of the Indenture, as amended by this Third Supplemental Indenture, the terms of the Indenture, as amended by this Third Supplemental Indenture, shall govern and be controlling.

The Trustee accepts the amendments of the Indenture effected by this Third Supplemental Indenture and agrees to execute the trust created by the Indenture as hereby amended, but only upon the terms and conditions set forth in the Indenture, including the terms and provisions defining and limiting its liabilities and responsibilities in the performance of the trust created by the Indenture as hereby amended.  Without limiting the generality of the foregoing, the Trustee shall not be responsible in any manner whatsoever for or with respect to any of the recitals or statements contained herein, all of which recitals or statements are made solely by the Company, and the Trustee makes no representation with respect to any such matters.  Additionally, the Trustee makes no representation or warranty as to the validity or sufficiency of this Third Supplemental Indenture.  For the avoidance of doubt, the Trustee, by executing this Third Supplemental Indenture in accordance with the terms of the Indenture, does not agree to undertake additional actions nor does it consent to any transaction beyond what is expressly set forth in this Third Supplemental Indenture, and the Trustee reserves all rights and remedies under the Indenture, as amended by this Third Supplemental Indenture.

Capitalized terms used herein and not otherwise defined herein are used with the respective meanings ascribed to such terms in the Indenture.  The words “herein,” “hereof” and “hereby” and other words of similar import used in this Third Supplemental Indenture refer to this Third Supplemental Indenture as a whole and not to any particular section hereof.

All of the covenants, stipulations, promises and agreements made in this Third Supplemental Indenture by each of the parties hereto shall bind its successors and assigns whether so expressed or not.

The article and section headings herein are for convenience only and shall not affect the construction hereof.

This Third Supplemental Indenture shall be deemed to be a contract made under the law of the State of New York, and for all purposes shall be governed by and construed in accordance with the law of the State of New York (without regard to the conflicts of laws principles thereof).

This Third Supplemental Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.  This Third Supplemental Indenture shall become effective and constitute a binding agreement between the parties hereto when counterparts hereof shall have been executed and delivered by each of the parties hereto.

In case any provision in this Third Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

To the extent of any inconsistency between the terms of the Indenture and this Third Supplemental Indenture, the terms of this Third Supplemental Indenture will control.  If any provision hereof limits, qualifies or conflicts with another provision hereof or of the Indenture which is required to be included in the Indenture by any of the provisions of the Trust Indenture Act, such required provisions shall control.

This Third Supplemental Indenture, together with the Indenture, constitutes the entire agreement of the parties hereto with respect to the amendments to the Indenture set forth herein.

Notwithstanding anything in the Indenture to the contrary, the words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Third Supplemental Indenture or any document to be signed in connection herewith, including by the Trustee, shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

IN WITNESS WHEREOF, the parties hereto have executed this Third Supplemental Indenture as of the date first above written.
