Such statements are subject to certain risks and uncertainties, including without limitation those discussed in the Company's 1996 Annual Report to Shareholders and Quarterly Reports on Form 10-Q for the quarters ended March 31, 1997, June 30, 1997 and September 30, 1997.

THE COMPANY UST Corp., a bank holding company registered with the Board of Governors of the Federal Reserve System (the "Federal Reserve Board"), was organized as a Massachusetts business corporation in 1967. The Company is also subject to examination by, and is required to file reports with, the Commissioner of Banks of the Commonwealth of Massachusetts (the "Massachusetts Commissioner"). As of December 31, 1996, the Company's banking subsidiaries were USTrust and United States Trust Company ("USTC"), each headquartered in Boston. USTrust and USTC are sometimes hereinafter collectively referred to as the "Subsidiary Banks." Subsequently, on January 3, 1997, the Company acquired Walden Bancorp, Inc. of Acton, Massachusetts ("Walden"), and its subsidiary banks, The Co-operative Bank of Concord ("Concord"), headquartered in Concord, and The Braintree Savings Bank ("Braintree") headquartered in Braintree. During the second quarter of 1997, Concord and Braintree, former subsidiaries of Walden, were merged with and into USTrust, the principal banking subsidiary of UST Corp. The Company's acquisition of Walden is discussed in further detail in the Company's Annual Report on Form 10-K under the caption "Recent Developments - Acquisition of Walden Bancorp, Inc." and the merger of Braintree, Concord and USTrust is described in the Company's Form 10-Q for the quarter ended June 30, 1997. Each of the Company's Subsidiary Banks are chartered under Massachusetts law. All of the capital stock of the Subsidiary Banks is owned directly or indirectly by the Company. In addition, the Company owns directly or indirectly through its banking subsidiaries, all of the outstanding stock of five active nonbanking subsidiaries, all Massachusetts corporations: UST Leasing Corporation, UST Capital Corp., UST Securities Corp., USTrust Securities Corp. and UST Auto Lease Corp., as well as five subsidiaries which hold foreclosed real estate. As a result of the Walden acquisition, the Company also acquired Concord's two nonbanking subsidiaries, Walden Financial Corp. and Walden Securities Corp., as well as one subsidiary which holds foreclosed real estate, and Braintree's nonbanking subsidiary, Braintree Securities Corp., as well as two subsidiaries which hold foreclosed real estate. On October 15, 1997, the Company acquired Firestone Financial Corp. ("Firestone") of Newton, Massachusetts, a small business equipment finance company. The Company's acquisition of Firestone is discussed in further detail below under the caption "Recent Developments - Firestone." The Company engages in one line of business, that of providing financial services through its banking and nonbanking subsidiaries. A broad range of financial services is provided principally to individuals and small-and medium-sized companies in New England including those located in low-and moderate-income neighborhoods within the Company's defined Community Reinvestment Act assessment area. In addition, an important component of the Company's financial services is the provision of trust and money management services to professionals, corporate executives, nonprofit organizations, labor unions, foundations, mutual funds and owners of closely-held businesses most of whom are located in the New England region. The executive office of UST Corp. is located at 40 Court Street, Boston, Massachusetts 02108 (Telephone (617) 726-7000). The Subsidiary Banks The Subsidiary Banks are engaged in a general banking business and accept deposits which are insured by the Federal Deposit Insurance Corporation ("FDIC"). USTC, which has full banking powers and accepts deposits which are insured by the FDIC, focuses its activity on trust and money management, venture capital and other fee-generating businesses. USTrust and USTC are commercial banks. The Subsidiary Banks are both located in Massachusetts. For the quarter ended September 30, 1997, the Company reported net income of $10.8m, or $0.37 per share, compared with net income of $16.0 million, or $0.57 per share, for the same period of 1996. The third quarter results in 1996 reflect a $14.6 million pre-tax earnings credit that was recorded through the provision for possible loan losses and a one-time charge of $3.0 million to reflect the Company's liability for an assessment on certain deposits insured by the Savings Association Insurance Fund. For the nine months ended September 30, 1997, net income was $19.4 million, or $0.67 per share, compared with $35.2 million, or $1.24 per share, for the first three quarters of 1996. Results for the 1997 period include a non-recurring charge of $3.1 million for certain non-deductible merger-related expenses (in respect of the Walden and Firestone acquisitons) and a pre-tax charge of $11.8 million for restructuring expenses associated with the acquisition of Walden, accounted for as a pooling of interest and completed in January, 1997. Results for the 1996 period include the aforementioned $14.6 million pre-tax earnings credit, a similar $5.2 million credit recorded in the second quarter and the $3.0 million one-time deposit insurance assessment. Recent Developments - Firestone On August 12, 1997, the Company announced the execution of a definitive agreement to acquire Firestone, an $85 million small business equipment finance company headquartered in Newton, Massachusetts. The transaction, which was consummated on October 15, 1997, was accounted for as a pooling of interests and was structured as a tax-free exchange of 0.63 shares of UST common stock for each of the 2.0 million outstanding closely held shares of Firestone common stock, up to a maximum value of $30 million. At the Company's closing price of $21.75 on August 8, 1997, the transaction was valued at approximately $27.4 million. Based on the Company's common stock average market value of $25.43 during the determination period set forth in the definitive agreement, the Company exchanged a total of 1,180,000 shares of common stock, representing an exchange ratio of 0.59 shares of UST for each share of Firestone. The Company's common stock exchanged for Firestone common stock was not registered prior to the effectiveness of the transaction and cannot be offered or resold absent registration or an applicable exemption from registration requirements. The Company has recorded a one-time, pre-tax charge of approximately $1 million for acquisition-related costs in connection with the transaction. Recent Developments - Somerset On December 9, 1997, the Company executed an Affiliation Agreement and Plan of Reorganization (the "Somerset Agreement") with Somerset Savings Bank ("Somerset"), pursuant to which Somerset will be merged with and into the Company's wholly-owned principal bank subsidiary, USTrust. Somerset is a Massachusetts savings bank which serves the consumer and small business banking needs of its customers through its five branch offices located in the Massachusetts communities of Somerville and Burlington. The Somerset transaction, which is structured to qualify as a pooling-of-interests for accounting purposes, is subject to the approval of the shareholders of Somerset as well as to the receipt of federal and state regulatory banking approvals. Subject to the foregoing conditions, the Somerset transaction is expected to close during the first half of 1998. The Somerset transaction is structured as a tax-free exchange of 0.19 shares of the Company's common stock for each share of Somerset's common stock. At the Company's closing stock price of $29.625 on December 9, 1997, the Somerset transaction would be valued at approximately $93.7 million, and Somerset shareholders would receive a value of $5.63 in Company common stock for each share of Somerset common stock. The purchase price represents a multiple of 2.43 times stated book value of Somerset at September 30, 1997. The Company expects to record a one-time pre-tax charge of approximately $7.5 million of acquisition related costs in connection with the Somerset transaction. Immediately after execution of the Somerset Agreement on December 10, 1997, the Company entered into a Stock Option Agreement with Somerset, pursuant to which Somerset has granted to the Company the option to purchase, under certain circumstances, 2,777,000 shares of Somerset common stock at an exercise price of $4.875 per share and has also granted the Company certain additional consideration related to the option. Recent Developments - Affiliated On December 15, 1997, the Company executed an Affiliation Agreement and Plan of Reorganization (the "Affiliated Agreement") with Affiliated Community Bancorp, Inc. ("Affiliated"), pursuant to which the Company will acquire Affiliated. Affiliated is a $1.1 billion bank holding company for three community banks, Lexington Savings Bank, The Federal Savings Bank and Middlesex Bank and Trust Company (together, the "Affiliated Banks") which serve consumer and small business banking needs through twelve branch offices located in eastern Middlesex County. The Affiliated transaction, which is structured to qualify as a pooling-of-interests for accounting purposes, is subject to the approval of the shareholders of the Company and Affiliated as well as to the receipt of federal and state regulatory banking approvals. The Affiliated transaction is expected to close during the first half of 1998. While the Company will first acquire Affiliated thereby making the Affiliated Banks subsidiaries of the Company, the Company anticipates merging the banks into its principal banking subsidiary, USTrust, in 1998. The Affiliated transaction is structured as a tax-free exchange of 1.41 shares of the Company's common stock for each share of Affiliated common stock. At the Company's closing stock price of $28.3125 on December 12, 1997, the Affiliated transaction would be valued at approximately $259 million, and Affiliated shareholders would receive a value of $39.92 in Company common stock for each share of Affiliated common stock. The purchase price represents a multiple of 2.3 times stated book value of Affiliated at September 30, 1997. The Company expects to record a one-time pre-tax charge of approximately $12 million of acquisition related costs in connection with the Affiliated transaction. If the Company's average stock price during a period prior to closing is less than $24.06 per share and the Company's stock price has declined by more than 15% relative to a certain bank stock index, Affiliated can terminate the agreement subject to the right of the Company to issue additional shares to ensure a per share value of $33.92 in stock of the Company. Immediately after execution of the Affiliated Agreement on December 15, 1997, the Company entered into a Stock Option Agreement with Affiliated pursuant to which Affiliated has granted to the Company the option to purchase, under certain circumstances, up to 1,300,078 shares of its outstanding stock for $32.937 per share. SELLING STOCKHOLDERS On October 15, 1997, the Stockholders of Firestone (the "Selling Stockholders") collectively acquired shares of the Common Stock from the Company in a transaction exempt from the registration requirement of the Securities Act, in connection with an Agreement and Plan of Reorganization dated as of August 12, 1997 (the "Acquisition Agreement") and related Agreement and Plan of Merger, dated as of October 15, 1997, pursuant to which a wholly-owned subsidiary of the Company merged into Firestone (with Firestone as the surviving entity), in exchange for shares of the Common Stock. The term Selling Stockholders includes the holders listed below and the beneficial owners of the Shares and their transferees, pledgees, donees and other successors. Pursuant to the Acquisition Agreement, the Company agreed to file with the Commission the Registration Statement, of which this Prospectus is a part, with respect to the resale of the Shares. The Company has committed to keep the Registration Statement effective until the earlier of (i) the first anniversary of the closing date under the Acquisition Agreement, or (ii) such time as all the shares of Common Stock covered by such Registration Statement have been sold. The Company has agreed to indemnify the Selling Stockholders and its officers, directors and controlling persons against certain liabilities, including certain liabilities under the Securities Act. As of October 14, 1997, except as noted below, none of the Selling Stockholders held of record any shares of the Company's outstanding Common Stock. Except as noted below, no Selling Stockholder has, within the past three years, had any position, office or other material relationship with the Company or its affiliates. As of December 19, 1997, there were 29,719,593 shares of the Common Stock issued and outstanding. The following table sets forth certain information regarding the beneficial ownership of the Common Stock as of December 17, 1997 and as adjusted to reflect the sale of all of the Common Stock offered hereby by the Selling Stockholders.

PLAN OF DISTRIBUTION The sale or distribution of the Shares may be effected directly to purchasers by the Selling Stockholders as a principal or through one or more underwriters, brokers, dealers or agents from time to time in one or more transactions (which may involve crosses or block transactions) (i) on any exchange or in the over-the-counter market, (ii) in transactions otherwise than in the over-the-counter market or (iii) through the writing of options (whether such options are listed on an options exchange or otherwise) on, or settlement of short sales of, the Shares. Any of such transactions may be effected at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale or at negotiated or fixed prices, in each case as determined by the Selling Stockholders or by agreement between the Selling Stockholders and underwriters, brokers, dealers or agents, or purchasers. The Selling Stockholders may effect such transactions by selling the Shares directly to purchasers or by selling shares to or through underwriters, brokers or dealers and such underwriters, brokers or dealers may receive compensation in the form of discounts, concessions or commissions from the Selling Stockholders or the purchasers of the Shares for whom such underwriters, brokers or dealers may act as agent, or to whom they sell as principal, or both (which compensation to a particular underwriter, broker or dealer might be in excess of customary commissions or be changed from time to time). The Selling Stockholders and any underwriters, brokers, dealers or agents who participate in a sale of the Shares may be deemed "underwriters" within the meaning of Section 2(11) of the Securities Act and the commissions paid or discounts allowed to any of such underwriters, brokers, dealers or agents in addition to any profits received on resale of the Shares if any of such underwriters, brokers, dealers or agents should purchase any Shares as a principal may be deemed to be underwriting discounts or commissions under the Securities Act. Certain of any such underwriters, dealers, brokers or agents may have other business relationships with the Company and/or its affiliates in the ordinary course. Under the securities laws of certain states, the Shares may be sold in such states only through registered or licensed brokers or dealers. The Company will pay all of the expenses incident to the registration, offering and sale of the Shares to the public hereunder other than commissions, fees and discounts of underwriters, brokers, dealers and agents. The Company has agreed to indemnify the Selling Stockholders and controlling persons (within the meaning of the Securities Act) against certain liabilities, including liabilities under the Securities Act. If all or a portion of the Shares are offered through an underwritten offering, the terms of such underwritten offering, including the initial public offering price, the names of the underwriters and the compensation, if any, of such underwriters, will be set forth in an accompanying Prospectus Supplement. Until the distribution of the Shares is completed, rules of the Commission may limit the ability of any underwriters and any other person participating in the distribution of the Shares to bid for and purchase the Common Stock. As an exception to these rules, underwriters are permitted to engage in certain transactions that stabilize the price of the Common Stock. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Common Stock. If any underwriters create a short position in the Shares in connection with the offering, selling more Shares than are set forth on the cover page of this Prospectus, the underwriters may reduce that short position by purchasing shares of Common Stock in the open market. Purchases of the Common Stock for the purpose of stabilization or to reduce a short position could cause the price of the Common Stock to be higher than it might be in the absence of such purchases. In addition, rules of the Commission may limit the timing of purchases and sales of shares of Common Stock by the Selling Stockholders and any other such person. All of the foregoing may limit the marketability of the Shares and the ability of any underwriter, broker, dealer or agent to engage in market making activities. USE OF PROCEEDS The Company will not receive any of the proceeds from the sale of any of the Shares by the Selling Stockholders. CERTAIN LEGAL MATTERS The validity of the offered Common Stock will be passed upon for the Company by Eric R. Fischer, Executive Vice President, General Counsel and Clerk of the Company. As of December 22, 1997, Mr. Fischer had a direct or indirect interest in 36,798 shares of Common Stock and had options to purchase an additional 50,800 shares, all of which options were immediately exercisable.

Indemnification of Directors and Officers. Section 67 of Chapter 156B of the Massachusetts General Laws authorizes a corporation to indemnify any director, officer, employee or other agent of the corporation to whatever extent specified in or authorized by (a) the articles of organization, (b) a by-law adopted by the stockholders or (c) a vote adopted by the holders of a majority of the shares of stock entitled to vote on the election of directors. The Registrant's Articles of Organization provide that the Registrant shall, to the fullest extent legally permissible, indemnify each person who is or was a director, officer, employee or other agent of the Registrant and each person who is or was serving at the request of the Registrant as such of another corporation or of any partnership, joint venture, trust, employee benefit plan or other enterprise or organization, against all liabilities, costs and expenses, including but not limited to amounts paid in satisfaction of judgments, in settlement or as fines and penalties, and counsel fees and disbursements, reasonably incurred by him or her in connection with the defense or disposition of or otherwise in connection with or resulting from any action, suit or other proceeding, whether civil, criminal, administrative or investigative, before any court or administrative or legislative or investigative body, in which he or she may be or may have been involved as a party or otherwise or with which he or she may be or may have been threatened, while in office or thereafter, by reason of his or her being or having been such a director, officer, employee, agent or trustee, or by reason of any action taken or not taken in any such capacity. Under Massachusetts law and the Articles, no indemnification may be provided for any person with respect to any matter as to which he or she shall have been adjudicated in any proceeding not to have acted in good faith in the reasonable belief that his or her action was in the best interest of the Registrant or other entity served or, to the extent that such matter relates to service with respect to an employee benefit plan, in the best interest of the participants or beneficiaries of such employee benefit plan. If, in an action, suit or proceeding brought by or in the name of the Registrant, a director of the Registrant is held not liable for monetary damages, whether because that director is relieved of personal liability under the provisions of the Articles of Organization, or otherwise, that director shall be deemed to have met the standard of conduct set forth above and to be entitled to indemnification for expenses reasonably incurred in the defense of such action, suit or proceeding. As to any matter disposed of by settlement pursuant to a consent decree or otherwise, no indemnification either for the amount of such settlement or for any other expenses shall be provided unless such settlement shall be approved as in the best interests of the Registrant, after notice that it involves such indemnification, (a) by vote of a majority of the disinterested directors then in office (even though the disinterested directors be less than a quorum), (b) by any disinterested person or persons to whom the question may be referred by vote of a majority of such disinterested directors, or (c) by vote of the holders of a majority of the outstanding stock at the time entitled to vote for directors, voting as a single class, exclusive of any stock owned by any interested person, or (d) by any disinterested person or persons to whom the question may be referred by vote of the holders or a majority of such stock. No such approval shall prevent the recovery from any such officer, director, employee, agent or trustee of any amounts paid to him or her or on his or her behalf as indemnification in accordance with the preceding sentence if such person is subsequently adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that his or her action was in the best interests of the Registrant. The right of indemnification provided in the Registrant's Articles of Organization shall not be exclusive of or affect any other rights to which any director, officer, employee, agent or trustee may be entitled or which may lawfully be granted to him or her. Indemnification of a "director", "officer", "employee", "agent", and "trustee" includes their respective executors, administrators and other legal representatives. An "interested" person is one against whom the action, suit or other proceeding in question or another action, suit or other proceeding on the same or similar grounds is then or had been pending or threatened, and a "disinterested" person is a person against whom no such action, suit or other proceeding is then or had been pending or threatened.

Fischer, Esq. 23.1 Consent of Eric R. Fischer (included in Exhibit 5). 23.2 Consent of Arthur Andersen LLP. 24 Power of Attorney (included on signature page). Item 17. Undertakings. (A) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (B) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (C) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (D) The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report, to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

("Firestone") and each of the stockholders of Firestone. In rendering this opinion as General Counsel of the Corporation, I and an attorney in my office acting under my direction have participated with the Corporation and its officers in the preparation, review and filing of the Registration Statement and the related prospectus (the "Prospectus"), have examined other corporate documents and records, have made such examination of law, and have discussed with the officers and directors of the Corporation and its subsidiaries such questions of fact as we have deemed necessary or appropriate. We have also relied upon certificates and statements of such officers and directors as to factual matters and have assumed the genuineness of all signatures not known to us as well as the authenticity of all documents submitted to us as copies.
