The Securities will be purchased and sold pursuant to a Investor Agreement (“Investor Agreement”) in the form set forth as an exhibit to the Registration Statement to be entered into between the Company and each purchaser of Securities (“Purchasers”) and issued pursuant to the Indenture, dated as of October 10, 2008 (“Initial Indenture”), as supplemented by the First Supplemental Indenture dated July 10, 2009 (“First Supplement”) and the Second Supplemental Indenture dated May 5, 2010 (“Second Supplement”, and together with the Initial Indenture and the First Supplement, the “Indenture”), each of which Initial Indenture, First Supplement and Second Supplement is between the Company and CSC Trust Company of Delaware, as successor to Wells Fargo Bank, National Association, as trustee (“Trustee”).

execution and delivery are prerequisites to the effectiveness thereof. We have also assumed that certificates or instruments representing the Securities will have been properly signed by authorized officers of the Company or their agents, properly authenticated in accordance with the terms of the Indenture and delivered to the intended recipients with the intent that the Company be bound thereby.

In rendering the opinions set forth below, we have assumed that: (i) the Trustee has the power, corporate or other, to enter into and perform its obligations under the Indenture; (ii) the Indenture, as supplemented, is, and at the time of execution, authentication, issuance and delivery of the Securities will be, duly authorized, executed and delivered by the parties thereto in substantially the form filed as an exhibit to the Registration Statement and reviewed by us and will be a valid and binding obligation of the Trustee; (iii) the Trustee shall have been qualified under the Trust Indenture Act of 1939, as amended; and (iv) each Purchaser, respectively, has the legal capacity or power, corporate or other, to enter into and perform such Purchaser’s obligations under the Investor Agreement.

We render this opinion only with respect to, and express no opinion herein concerning the application or effect of the laws of any jurisdiction other than, the existing laws of the United States of America and of the State of California, the existing Delaware General Corporation Law and reported judicial decisions relating thereto and, solely with respect to whether or not the Indenture and the Securities are the valid and binding obligations of the Company, the existing internal laws of the State of New York without regard to principles or laws regarding choice of law or conflict of laws.

With respect to our opinion expressed in paragraph (1) below as to the valid existence and good standing of the Company under the laws of the States of Delaware and California we have relied solely upon the Certificates of Good Standing and representations made to us by the Company.

This opinion is limited to laws, including rules and regulations, as in effect on the date hereof. We are basing this opinion on our understanding that, prior to issuing any Securities, the Company will advise us in writing of the terms thereof and other information material thereto, will afford us an opportunity to review the operative documents pursuant to which such Securities are to be issued (including the Registration Statement, the Prospectus and the applicable Prospectus Supplement, as then in effect) and will file such supplement or amendment to this opinion (if any) as we may reasonably consider necessary or appropriate with respect to such Securities. We also assume the Company will timely file any and all supplements to the Registration Statement and Prospectus as are necessary to comply with applicable laws in effect from time to time. However, we undertake no responsibility to monitor the Company’s future compliance with applicable laws, rules or regulations of the Commission or other governmental body.

This opinion is qualified by, and is subject to, and we render no opinion with respect to, the following limitations and exceptions to the enforceability of the Securities:

(a) the effect of the laws of bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent conveyance, and other similar laws now or hereafter in effect relating to or affecting the rights and remedies of creditors;

(b) the effect of general principles of equity and similar principles, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, public policy and unconscionability, and the possible unavailability of specific performance, injunctive relief, or other equitable remedies, regardless of whether considered in a proceeding in equity or at law;

(c) the effect of laws relating to usury or permissible rates of interest for loans, forbearances or the use of money; and

(d) the effect of provisions relating to indemnification, exculpation or contribution, to the extent such provisions may be held unenforceable as contrary to federal or state securities laws.

This opinion is based upon the customary practice of lawyers who regularly give, and lawyers who regularly advise opinion recipients regarding, opinions of the kind set forth in this opinion letter, including customary practice as described in bar association reports.

Based upon the foregoing, we are of the following opinion:

(1) The Company is a corporation validly existing, in good standing, under the laws of the State of Delaware;

(2) The Indenture has been duly authorized and executed by the Company and has been duly delivered by the Company to the Trustee and is the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms; and

(3) The Securities have been duly authorized and, when duly executed, authenticated and delivered by the Company and authenticated by the Trustee in accordance with the provisions of the Indenture and delivered to, and paid for by, the Purchasers in accordance with the terms of the Investor Agreement, will constitute legal, valid and binding obligations of the Company entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms.

We consent to the use of this opinion as an exhibit to the Registration Statement and further consent to all references to us, if any, in the Registration Statement, the Prospectus constituting a part thereof and any amendments thereto.

This opinion is intended solely for use in connection with issuance and sale of the Securities subject to the Registration Statement and is not to be relied upon for any other purpose. This opinion is rendered as of the date first written above and based solely on our understanding of facts in existence as of such date after the aforementioned examination. We assume no obligation to advise you of any fact, circumstance, event or change in the law or the
