Exhibit 99.4

                                 GIFT INSTRUMENT

                               CHARITABLE GIFT TO
                       HAMPDEN BANK CHARITABLE FOUNDATION

     Hampden Bancorp, Inc., 19 Harrison Avenue, Springfield, Massachusetts (the
"Company"), desires to make a gift of shares of its common stock (the "Common
Stock") to the Hampden Bank Charitable Foundation (the "Foundation"), a
nonprofit corporation organized under the laws of the State of Delaware. The
purposes of the gift are to support the charitable activities of the Foundation,
to establish a bond between the Company and the communities within which Hampden
Bank maintains a banking office, and to enable the communities to share in the
potential growth and success of the Company and it affiliates over the long
term. To that end, Hampden Bancorp, Inc. now gives, transfers, and delivers to
the Foundation ______shares of its Common Stock, subject to the following
conditions:

     1.   The Foundation shall use the donation solely for charitable purposes,
including community development, in the communities in which Hampden Bank
maintains a banking office, in accordance with the provisions of the
Foundation's Certificate of Incorporation; and

     2.   Consistent with the Company's intent to form a long-term bond between
the Company and the community, the amount of Common Stock that may be sold by
the Foundation in any one year shall not exceed 5% of the market value of the
assets held by the Foundation, except that this restriction shall not prohibit
the board of directors of the Foundation from selling a greater amount of Common
Stock in any one year if the board of directors of the Foundation determines
that the failure to sell a greater amount of the Common Stock held by the
Foundation would: (a) result in a long-term reduction of the value of the
Foundation's assets relative to their then current value that would jeopardize
the Foundation's capacity to carry out its charitable purposes; or (b) otherwise
jeopardize the Foundation's tax-exempt status.

     3.   The Common Stock contributed to the Foundation by the Company shall,
for so long as such shares of Common Stock are held by the Foundation, be
considered by the Company to be voted in the same ratio as all other shares of
Common Stock of the Company which are voted on each and every proposal
considered by stockholders of the Company; provided, however that this voting
restriction shall have no force and effect in the event that such restriction is
waived by the Massachusetts Division of Banks.
