HUDSON, Mass. & WESTBOROUGH, Mass. -- Assabet Valley Bancorp, Hudson Savings Bank, Westborough Bancorp, MHC ("Westborough MHC"), Westborough Financial Services, Inc.

According to Mark O'Connell, President of Hudson Savings Bank, "This is a win-win-win. It's a win for both banks--we share a commitment to community banking and will be much stronger as a larger more diverse institution. It's a win for the communities we serve because we will be even better equipped to offer competitive products and more services. And it's a win for the employees of both banks who will have greater opportunities that a larger company can offer."

Joe MacDonough, President of Westborough Bank and Westborough Financial, echoed O'Connell's sentiments. "This is a terrific opportunity to create a larger, stronger bank that will build on the traditions of Westborough Bank and Hudson Savings Bank. Additionally, I am pleased to say that there will be no layoffs or branch closings. This merger will ensure that there will continue to be a locally-owned, locally controlled bank in our communities."

Hudson Savings Bank is a Massachusetts-chartered savings bank which is wholly-owned by Assabet Valley Bancorp, a Massachusetts-chartered mutual holding company. Westborough Bank is a Massachusetts-chartered stock savings bank which is wholly-owned by Westborough Financial, a Massachusetts-chartered mid-tier holding company and majority-owned subsidiary of Westborough MHC, a Massachusetts-chartered mutual holding company.

Pursuant to the Agreement, the mutual holding company structure of Westborough MHC will be eliminated and Westborough Bank will ultimately merge with Hudson Savings Bank. The combined bank will be renamed prior to the completion of the transactions. The stockholders of Westborough Financial, other than Westborough MHC, will receive $35.00 in cash in exchange for each share of common stock.

Pursuant to the Agreement, all of the trustees and corporators of Westborough MHC will be elected or appointed to Assabet Valley Bancorp's Board of Trustees and Board of Corporators and Mr. MacDonough will serve as President and Chief Executive Officer of Assabet Valley Bancorp. The Board of Directors of the combined bank will be comprised of nine current Westborough Financial directors and fifteen current Hudson Savings Bank directors. Mr. O'Connell will serve as President and CEO of the new combined Bank and Mr. MacDonough will serve as an Executive Vice President.

The transactions are subject to several conditions, including the receipt of regulatory approvals and the approval of the stockholders Westborough Financial and the corporators of Westborough MHC and Assabet Valley Bancorp. It is anticipated that the transactions will be completed in spring of 2007 at which time Hudson Savings Bank and Westborough Bank will begin combining systems, data and personnel.
