DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED. On November 15, 1994, the Board of Directors of the Registrant declared a dividend distribution of one Right for each outstanding share of Registrant's common stock to stockholders of record at the close of business on November 15, 1994. See the Registrant's Form 8-A, dated November 29, 1994, Registrant's Form 8-A/A, Amendment No. 1, dated December 21, 1999, and Registrant's Form 8-A/A, Amendment No. 2, dated February 24, 2000, for a complete description of the Rights Agreement (the "Rights Agreement") between the Registrant and American Stock Transfer Trust Company, as Rights Agent (the "Rights Agent") , as amended as of December 16, 1999. Since adoption of the Rights Agreement, new certificates for the Registrant's common stock issued after November 15, 1994, contained a notation incorporating the Rights Agreement by reference. On April 19, 2000, the Registrant and BSB Bancorp, Inc. ("BSB") executed an Agreement and Plan of Merger (the "Merger Agreement") providing for, among other things, the merger of BSB with and into Registrant. In connection with the execution of the Merger Agreement, the Registrant executed an amendment (the "Amendment") to the Rights Agreement in order to amend the definition of "Acquiring Person" set forth in the Rights Agreement to provide that neither BSB nor any affiliated or associated party (collectively with BSB, the "BSB Parties") will be deemed to be an Acquiring Person by virtue of the fact that BSB is the Beneficial Owner (as defined in the Rights Agreement) solely of shares of Registrant common stock (i) of which any BSB Party is or becomes the Beneficial Owner by reason of the approval, execution or delivery of the Merger Agreement or the Stock Option Agreement, dated as of April 19, 2000, between the Registrant, as issuer, and BSB, as grantee (the "Stock Option Agreement"), or by reason of the consummation of any transaction contemplated in the Merger Agreement, the Stock Option Agreement or both, (ii) of which any BSB Party is the Beneficial Owner on April 19, 2000, (iii) acquired in satisfaction of debts contracted prior to April 19, 2000, in good faith in the ordinary course of such BSB Party's banking business, (iv) held by any BSB Party in a bona fide fiduciary or depository capacity or (v) owned in the ordinary course of business by either (A) an investment company registered under the Investment Company Act of 1940, as amended, or (B) an investment account, in either case for which any BSB Party acts as investment advisor. The Rights may have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire the Registrant without conditioning the offer on a substantial number of Rights being acquired. However, the Rights should not interfere with any merger or other business combination approved by the Board of Directors. A copy of the Rights Agreement between the Registrant and the Rights Agent specifying the terms of the Rights is incorporated herein by reference. The foregoing description of the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement, as amended. ITEM 2.
