which
are approximately 40% higher than Ben Franklin`s pro forma
tangible
book multiple.
13. In addition, please advise why the book value multiple isn`t

14. It appears that Stock-Based Benefit Plans will dilute
shareholder
ownership interest.  Please revise accordingly.

Pro Forma Balance Sheets - page 36

cash
and cash equivalents rather than securities available for sale at
fair value.  Please revise.
17. Please revise the footnotes here and on your pro forma

business
unit acquired.  On page F-14, you state that you do not track the
separate value of Foxboro National Bank (to which all of your
goodwill relates).
* Tell us in detail how you followed the guidance in paragraph 30

operating, investing and financing activities.  Since there has

reasons for the changes, as well as their reasonably likely impact

prospective information regarding short and long term sources of
capital and the need for capital.  Specifically, discuss how the

In

addition compensation from Benjamin Franklin Bancorp by
participating
in their "intention to fund our stock-based incentive plan with

the amounts purchased represent purchases of loans or purchases of
loan participations.  Refer to paragraph 21 of SFAS 104.
33. Please revise to provide a separate line item in operating

characteristics of the underlying financial assets used to

state
what these interest rates and terms are.

Summary of Significant Accounting Policies- Derivative Financial
Instruments - page F-14
36. Please expand your accounting policy for derivative financial

the conclusion for each that no other-than-temporary loss should
be
recognized in the statement of income.

Note 6- Servicing - page F-25
40. Supplementally tell us how the fair values of your mortgage
servicing assets were determined for each period presented.  We
would
expect the fair values to be lower than the carrying values in a

disclosures required by paragraph 17e (4) of SFAS 140.

Business of Chart Bank - Lending Activities- page 120
46. You state that you typically sell fixed-rate residential
mortgage
loans originated; however, your table on page 121 does not
quantify
sales of these loans.  Please revise your disclosures for
consistency. Also, revise your accounting policy for loans to
state
how these loans are accounted for.  Specifically state whether or
not
you retain the right to service these loans.  To the extent that

proceeding
initiated by the Commission or any person under the federal
securities laws of the United States.
