          Re:      Registration Statement on Form S-4
Ladies and Gentlemen:
          I and other members of my staff have acted as counsel to Bank of America Corporation, a Delaware corporation (the “Company”), in connection with the registration statement on Form S-4, as amended (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Act”), for the registration of shares of the Company’s common stock, par value $0.01 per share (the “Securities”), that may be issued in connection with the merger of MBNA Corporation, a Maryland corporation (“MBNA”), with and into the Company (the “Merger”), as described in the Registration Statement.
          In rendering this opinion, I have examined such corporate records and other documents, and I have reviewed such matters of law, as I have deemed necessary or appropriate. Based on the foregoing, I am of the opinion that all necessary corporate action on the part of the Company has been taken to authorize the issuance of the Securities in connection with the Merger, and when the Registration Statement has been declared effective by order of the Commission and the Securities have been issued in accordance with the terms and conditions set forth in the Agreement and Plan of Merger, dated as of June 30, 2005, between the Company and MBNA, the Securities will be validly issued, fully paid and nonassessable.
          The foregoing opinion is limited to the federal law of the United States of America and the General Corporation Law of the State of Delaware.
