EXHIBIT 5.1 February 23, 1994 Securities & Exchange Commission 450 Fifth Street, N.W. Washington, D.C. 20549 Dear Sirs: I am a Senior Vice President and the General Counsel of Alliance Capital Management Corporation, General Partner of Alliance Capital Management L.P., a Delaware limited partnership (the "Partnership"), and have acted as counsel in connection with the registration under the Securities Act of 1933, as amended (the "Securities Act"), of up to 750,000 Units representing assignments of beneficial ownership of 750,000 limited partnership interests in the Partnership (the "Retention Bonus Units"), issuable pursuant to the Alliance Capital Management L.P. Shields/Regent Retention Unit Bonus Plan (the "Retention Bonus Plan"), as described in the Registration Statement on Form S-8 filed herewith (the "Registration Statement"). Capitalized terms used herein and not otherwise herein defined are used as defined in the Agreement of Limited Partnership of the Partnership (As Amended and Restated), (the "Partnership Agreement"). As counsel for the Partnership, I, or attorneys under my supervision, have participated in the preparation of the Registration Statement and have examined and relied upon such documents, opinions, precedents, records and other materials as I have deemed necessary or appropriate to provide a basis for the opinions set forth below. In this examination, I have assumed the genuineness of all signatures, the authenticity of all documents submitted to me as original documents and conformity to original documents of all documents submitted to me as certified or photostatic copies. I have further assumed for the purposes of this opinion: (i) compliance with the terms, conditions and restrictions set forth in the Partnership Agreement, the Registration Statement, the Retention Bonus Plan, the terms and conditions of which are set forth in Restricted Limited Partnership Units Acquisition Agreements to be executed by 2 the Partnership and each of five senior executives of Shields Asset Management, Incorported and Regent Investor Services Incorporated in connection with the acquisition of the Retention Bonus Units (collectively, the "Operative Documents") in connection with the issuance of Limited Partnership Interests and corresponding Retention Bonus Units; (ii) that appropriate notation of the names, addresses and capital contributions of the Assignor Limited Partner and persons acquiring Retention Bonus Units under the Retention Bonus Plan ("Unitholders") will be made in the books and records of the Partnership in connection with the issuance of Limited Partnership Interests and corresponding Retention Bonus Units; (iii) that the business of the Partnership has been and will be conducted in accordance with the terms of the Partnership Agreement and the Delaware Revised Uniform Limited Partnership Act, 6 DEL. C. Section 17-101, ET. SEQ. (the "Delaware Act"); and (v) that, prior to the issuance of any Retention Bonus Units by the Partnership, the Partnership shall have received an Assignment Determination, Limited Liability Determination and a Tax Determination with respect to such issuance. Based on the foregoing, I am of the opinion that: 1. The Partnership is a duly formed and validly existing limited partnership in good standing under the laws of the State of Delaware. 2. Retention Bonus Units to be issued to employees of the Partnership, and the corresponding Limited Partnership Interests to be issued to the Assignor Limited Partner, when issued in accordance with the terms, conditions and restrictions set forth in the Operative Documents, will constitute legally issued and fully paid Retention Bonus Units or Limited Partnership Interests, and will not be subject to assessment by the Partnership for additional capital contributions (except as such assessability may be affected by the matters referenced in paragraph 3 below). 3. No provision of the Partnership Agreement provides for or permits any Limited Partner or Unitholder (in such capacity, collectively, a "Holder"), to take action which, under the Delaware Act, would constitute participating in the control of the business of the Partnership so as to make the Holder taking such action liable as a general partner for the debts and obligations of the Partnership and, provided that a Holder in fact does not participate in the control of the business of the Partnership, the liability of such Holder, in his capacity as such, under the Delaware Act and the Partnership Agreement will be limited to an 3 amount not in excess of the sum of (a) any capital contribution to be made by such Holder (or his predecessor in interest) under the Operative Documents in respect of all Limited Partnership Interests or Retention Bonus Units acquired by such Holder, together with any undistributed partnership income, profits or property to which such Holder may be entitled on account of his ownership of Limited Partnership Interests or Retention Bonus Units; (b) the amount of any distribution made to such Holder to the extent the same is required to be returned to or for the account of the Partnership pursuant to Section 17-607 of the Delaware Act or the terms of the Partnership Agreement, potentially with interest; and (c) the amount of any liability of such Holder to the Partnership by reason of any tax payments made by the Partnership on such Holder's behalf as provided in Section 9.5 of the Partnership Agreement. As to matters of Delaware law contained in the foregoing opinion, I have relied on the opinion of Morris, Nichols, Arsht & Tunnell of Wilmington, Delaware, dated February 23, 1994. I consent to the filing of this opinion as an exhibit to the Registration Statement. Very truly yours, /s/ David R. Brewer, Jr. ------------------------ David R. Brewer, Jr.
