We have reviewed the Agreement and Plan of Merger, dated May 22, 1997, between HNB and Winter Park, and the related Supplemental Agreement, dated May 22, 1997, among Huntington, HNB, and Winter Park (collectively, the "Merger Documents"), Huntington's Articles of Restatement of Charter, Huntington's Bylaws, the corporate action taken to date in connection with the Registration Statement and the issuance and sale of the Stock, and such other documents and authorities as we deem relevant for the purpose of this opinion. Based upon the foregoing, we are of the opinion that: (a) upon the proper approval of the Merger Documents by the shareholders of Winter Park; (b) upon the approval of the Merger by the Office of the Comptroller of the Currency and the expiration of all applicable waiting periods; (c) upon compliance with the Securities Act of 1933, as amended, and with the securities or "blue sky" laws of the states in which the Stock is to be offered for sale; and (d) upon the "Effective Time," as defined in the Merger Documents; the Stock, when issued and delivered as provided in the Merger Documents in accordance with the resolutions adopted by the Board of Directors of Huntington, will be legally issued, fully paid, and nonassessable. We consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name under the caption "Legal Opinions" in the Prospectus included in the Registration Statement.
