We are of the opinion that the Company is a corporation duly organized and validly existing under the laws of the State of Mississippi.

Subject to the qualifications hereinafter expressed, we are of the further opinion that the Bonds and the Debt Securities, each when issued and delivered for the respective consideration contemplated by, and otherwise as respectively contemplated in, the Registration Statement, will respectively be legally issued and will be binding obligations of the Company, except as may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization or other similar laws affecting enforcement of mortgagees' and other creditors' rights and by general equitable principles (whether considered in a proceeding in equity or at law).

For purposes of the opinions set forth above, we have assumed (1) that the Bonds and the Debt Securities each will be issued and delivered in compliance with appropriate action with regard to the issuance of the Bonds and the Debt Securities, respectively, by and before the Securities and Exchange Commission under the Public Utility Holding Company Act of 1935, as amended, and (2) that the Bonds and the Debt Securities each will be issued and delivered in compliance with the due authorization, respectively, of the Company's Board of Directors and/or, when authorized, the Executive Committee thereof and/or an authorized officer of the Company.

This opinion is limited to the laws of the States of Mississippi and New York. To the extent that the opinions relate to or are dependent upon matters governed by the laws of the State of New York, we have relied upon the opinion of Thelen Reid & Priest LLP of New York, New York, which is being filed as Exhibit 5(b) to the Registration Statement.

We hereby consent to the filing of this opinion as Exhibit 5(a) to the Registration Statement and to the references to our firm, as counsel, in the Registration Statement and in the prospectus contained therein.
