Item 1.01  Entry into a Material Definitive Agreement.

      On May 15, 2007, Assabet Valley Bancorp ("Assabet") waived compliance by
Westborough Bancorp, MHC ("Westborough MHC") with the Voting Agreement dated as
of November 13, 2006 among Westborough MHC, Westborough Financial Services,
Inc. (the "Company") and Assabet.

      The Voting Agreement had been entered into in connection with the
execution of an Agreement and Plan of Merger dated as of November 13, 2006
among Assabet, its subsidiaries Hudson Savings Bank and HudWest Financial
Services, Inc., Westborough MHC and the Company and its subsidiary, The
Westborough Bank (the "Merger Agreement"). The Voting Agreement had required,
among other things, that Westborough MHC vote its shares of the Company in
favor of the Merger Agreement. The waiver enables Westborough MHC to vote its
shares of the Company as determined by Westborough MHC's Board of Trustees.

      As a condition to granting the waiver, Assabet required that the Merger
Agreement be amended. The Merger Agreement was amended on May 15, 2007 in order
to clarify the circumstances under which the breakup fee contained therein
would be payable to Assabet and to extend, from June 30, 2007 to August 15,
2007, the date after which the Merger Agreement could be terminated if the
merger contemplated thereby had not been consummated.

      A copy of Amendment No. 1 to the Merger Agreement is attached hereto as
Exhibit 99.1.

Item 9.01  Financial Statements and Exhibits.
