(1) The shares of Issuer common stock covered by the initial report had been purchasable by Reporting Person upon exercise of an option granted by issuer to Reporting Person as of April 19, 2000, and described in Item 4 of this report. On October 4, 2000, Issuer and Reporting Person agreed to terminate the option subject to the initial report and this report. See Item 4 below for a discussion of the Option. ITEM 1. SECURITY AND ISSUER. This statement on Schedule 13D/A (the "Schedule 13D/A") relates to the common stock, $.01 par value per share (the "Shares" or the "Issuer Common Stock"), of BSB Bancorp, Inc., a Delaware corporation ("Issuer"). The principal executive office of issuer is located at 58-68 Exchange Street, Binghamton, New York 13901. The purpose of filing this Schedule 13D/A is to report the agreement between Issuer and Reporting Person, dated as of October 4, 2000, to terminate that certain Agreement and Plan of Merger between Issuer and Reporting Person, dated as of April 19, 2000 (the "Plan of Merger"), including the Option (as discussed in Items 3 and 4 below). 3 The information set forth in the Exhibit hereto is hereby expressly incorporated herein by reference and the responses to each item of this Schedule 13D/A are qualified in their entirety by the provisions of such Exhibit. ITEM 2. IDENTITY AND BACKGROUND. (a)-(c) This Schedule 13D/A is filed by NBT Bancorp Inc., a Delaware Corporation ("Reporting Person"). The business address of Reporting Person is 52 South Broad Street, Norwich, New York 13815. The principal business of Reporting Person is a bank holding company. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. The Option (defined in Item 4 below) to acquire shares was granted by Issuer to Reporting Person as an inducement to Reporting Person's entering into the Plan of Merger, providing for the merger of Issuer into Reporting Person with Reporting Person being the surviving corporation (the "Merger"). Pursuant to the Plan of Merger, each outstanding Share would have been converted into the right to receive two shares of common stock, par value $.01 per share, of Reporting Person ("Reporting Person Common Stock"). The Merger was subject to the approval of Issuer's and Reporting Person's stockholders, respectively, regulatory approvals, and the satisfaction or waiver of various other conditions, as more fully described in the Plan of Merger. None of the Purchase Events (defined in Item 4 below) permitting the exercise of the Option had occurred as of the date hereof. ITEM 4. PURPOSE OF THE TRANSACTION. The information set forth in Item 3 is hereby incorporated herein by reference. The purpose of the transaction was for Issuer to merge with and into Reporting Person, with reporting person being the surviving entity. In connection with the Plan of Merger and in consideration thereof, Issuer and Reporting Person entered into that certain Stock Option Agreement (the "Option Agreement"), dated April 19, 2000, whereby Issuer granted to Reporting Person an option (the "Option"). Under the Option, Reporting Person was given the right to purchase, under certain circumstances described therein, up to 19.9% of the total number of outstanding shares of Issuer Common Stock as of the first date that the Option would become exercisable. The Option, being exercisable for approximately 19.9% of the outstanding Shares, would represent approximately 16.6% of the Shares that would be outstanding after giving effect to the exercise of the Option. On October 4, 2000, the Boards of Directors of NBT and BSB agreed to terminate the Plan of Merger and the Option. 4 ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (c) To the best of Reporting Person's knowledge as of the date hereof, (i) neither Reporting Person nor any subsidiary or affiliate of Reporting Person nor any of Reporting Person's executive officers or directors beneficially owns any shares of Issuer Common Stock, and (ii) except for the Option discussed in Items 3 and 4 above, there have been no transactions in the shares of Issuer Common Stock effected during the past 60 days by Reporting Person, nor to the best of Reporting Person's knowledge, by any subsidiary or affiliate of Reporting Person or any of Reporting Person's executive officers or directors.
