April 7, 1998 Uno Restaurant Corporation 100 Charles Park Road West Roxbury, MA 02132 RE: Uno Restaurant Corporation Registration Statement on Form S-8 ---------------------------------- Dear Ladies and Gentlemen: We have acted as legal counsel to Uno Restaurant Corporation, a Delaware corporation (the "Company"), in connection with the preparation and filing of a Registration Statement on Form S-8 (the "Registration Statement") with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Act"), relating to 1,075,000 shares of the Company's Common Stock, $.01 par value (the "Shares"). The Shares are to be issued upon exercise of options granted pursuant to the: (1) Uno Restaurant Corporation 1997 Key Officer Stock Option Plan; and (2) Uno Restaurant Corporation 1997 Non-Qualified Stock Option Plan for Non-Employee Directors (together, the "Plans"). In connection with this Opinion Letter, we have examined the Registration Statement and the other documents listed on SCHEDULE A attached hereto (collectively, the "Documents"). We have not made any independent review or investigation of orders, judgments, rules or other regulations or decrees by which the Company or any of its property may be bound, nor have we made any independent investigation as to the existence of actions, suits, investigations or proceedings, if any, pending or threatened against the Company. With your concurrence, the opinion hereafter expressed is based solely upon (i) our review of the Documents, (ii) discussions with certain officers of the Company with respect to the Documents, (iii) discussions with those of our attorneys who have given substantive legal representation to the Company in connection with the Registration Statement, and (iv) such review of published sources of law as we have deemed necessary. This firm, in rendering legal opinions, customarily makes certain assumptions which are described in SCHEDULE B hereto. In the course of our representation of the Company in connection with the Registration Statement, nothing has come to our attention which causes us to believe reliance upon any of those assumptions is inappropriate, and, with your concurrence, the opinion hereafter expressed is based upon those assumptions. For purposes of those assumptions, the Enumerated Party referred to in SCHEDULE B is the Company. Our opinion hereafter expressed is limited to the laws of the Commonwealth of Massachusetts, Federal law and the General Corporation Law of the State of Delaware. We express no legal opinion upon any matter other than as explicitly addressed in numbered paragraph 1 below, and our express opinion therein contained shall not be interpreted to be implied opinions upon any other matter. Based upon and subject to the foregoing, we are of the opinion that: 1. The Shares have been duly authorized, and when issued in accordance with the terms of the Plans, will be validly issued, fully paid and nonassessable. II-9 2 We hereby consent to the filing of this opinion as an Exhibit to the Registration Statement and to the reference to this firm wherever it appears in the Registration Statement.
