      The Articles of Organization of the Corporation contains certain
provisions, applicable upon the effective date of the reorganization of
Westborough Savings Bank from a Massachusetts mutual savings bank to a
Massachusetts stock savings bank and the concurrent acquisition by the
Corporation of all of the outstanding capital stock of The Westborough Bank,
that restrict persons from directly or indirectly acquiring or holding, or
attempting to acquire or hold, the beneficial ownership of, in excess of 10% of
the outstanding shares of capital stock of the Corporation entitled to vote
generally in the election of directors ("Voting Stock"), exclusive of the shares
beneficially owned by Westborough Bancorp, MHC. The Articles of Organization
contain a provision pursuant to which the holders of shares in excess of 10% of
the Voting Stock of the Corporation are limited to one hundredth (1/100) of one
vote per share with respect to such shares in excess of the 10% limitation. In
addition, the Corporation is authorized to refuse to recognize a transfer or
attempted transfer of any shares of Voting Stock to any person who beneficially
owns, or who the Corporation believes would become by virtue of such transfer
the beneficial owner of, in excess of 10% of the Voting Stock, exclusive of the
shares beneficially owned by Westborough Bancorp, MHC. These restrictions are
not applicable to underwriters in connection with a public offering of the
common stock, certain reorganization transactions described in the Articles of
Organization or to acquisitions of Voting Stock by the Corporation, any
majority-owned subsidiary of the Corporation, or any pension, profit-sharing,
stock bonus or other compensation plan maintained by the Corporation or by a
member of a controlled group of corporations or trades or businesses of which
the Corporation is a member for the benefit of the employees of the Corporation
and for any subsidiary, or any trust or custodial arrangement established in
connection with any such plan.

      The Articles of Organization of the Corporation contains provisions
providing that the affirmative vote of the holders of at least 80% of the Voting
Stock of the Corporation may be required to approve certain business
combinations and other transactions with persons who directly or indirectly
acquire or hold the beneficial ownership of in excess of 10% of the Voting Stock
of the Corporation.

      The Corporation will furnish to any shareholder upon written request and
without charge, a statement of the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof and the qualifications, limitations or restrictions of such
preferences and/or rights. Such request may be made to the Corporation or to its
