In connection with this opinion, we have exam- ined originals or copies, certified or otherwise identi- fied to our satisfaction, of (i) the Registration State- ment; (ii) the Certificate of Trust of the Trust filed with the Secretary of State of the State of Delaware on May 14, 1997; (iii) the form of the Declaration; (iv) the form of the Capital Securities and a specimen certificate thereof; and (v) the form of the Purchase Agreement (the "Purchase Agreement") proposed to be entered into among the Company, the Trust and the representatives for the Underwriters named therein (collectively, the "Underwrit- ers") relating to, among other things, the sale of the Capital Securities. We have also examined originals or copies, certified or otherwise identified to our satis- faction, of such other documents, certificates and re- cords as we have deemed necessary or appropriate as a basis for the opinions set forth herein. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photo- static copies and the authenticity of the originals of such copies. In making our examination of documents executed or to be executed by parties other than the Trust, we have assumed that such parties had or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. In addition, we have assumed that the Declaration and the Capital Securities when executed will be in substantially the forms reviewed by us. As to any facts material to the opinions expressed herein which we did not independently establish or verify, we have relied upon oral or written statements and representations of BankBoston Capital Trust III BankBoston Corporation May 29, 1997 Page 3 officers, trustees and other representatives of the Company, the Trust and others. Members of our firm are admitted to the bar in the State of Delaware, and we do not express any opinion as to laws of any other jurisdiction. Based upon and subject to the foregoing and the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that when (i) the Registration Statement becomes effective; (ii) the Decla- ration and the Purchase Agreement have been duly executed and delivered by the parties thereto; (iii) the Declara- tion has been qualified under the Trust Indenture Act of 1939, as amended; and (iv) the terms of the Capital Securities have been duly established in accordance with the Declaration and the Capital Securities have been duly executed and authenticated in accordance with the Decla- ration and delivered to and paid for by the Underwriters as contemplated by the Purchase Agreement, the Capital Securities will have been duly authorized for issuance by the Trust and will be validly issued, fully paid and nonassessable, representing undivided beneficial inter- ests in the assets of the Trust; and the holders of the Capital Securities will be entitled to the same limita- tion of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware. We bring to your attention, however, that the holders of the Capital Securities may be obligated, pursuant to the Declaration, to (i) provide indemnity and/or security in connection with, and pay taxes or governmental charges arising from, transfers of Capital Securities and the issuance of replacement Capital Securities and (ii) provide security and indemnity in connection with re- quests of or directions to the Property Trustee to exer- cise its rights and powers under the Declaration.
