NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

      BASIS OF PRO FORMA PRESENTATION

      The unaudited pro forma condensed combined financial information related
      to the merger is presented as of and for the year ended December 31, 2004.
      The pro forma adjustments included herein reflect the $46.6 million
      purchase price paid for the 1.4 million shares of Chart Bank common stock
      outstanding at April 4, 2005. The total merger consideration consisted of
      approximately $21.5 million in cash and 2.5 million shares of Benjamin
      Franklin Bancorp common stock. The pro forma adjustments also include the
      conversion of Benjamin Franklin Bancorp, a Massachusetts-chartered mutual
      holding company, to a Massachusetts-chartered business corporation and
      stock holding company and simultaneous stock offering of 5,577,419 shares
      of common stock at $10.00 per share to eligible account holders. An
      additional 400,000 shares were issued and contributed to the Benjamin
      Franklin Bank Charitable Foundation as part of the conversion.

      The merger has been accounted for using the purchase method of accounting;
      and accordingly, Benjamin Franklin's cost to acquire Chart Bank has been
      allocated to the assets and liabilities at their respective fair values as
      of the date the merger was completed.

      The unaudited pro forma condensed combined financial information includes
      estimated adjustments to record the assets and liabilities of Chart Bank
      at their respective fair values and represents management's estimates
      based on available information. The pro forma adjustments included herein
      may be revised as additional information becomes available and as
      additional analyses are performed. The final allocation of the purchase
      price will be determined after completion of a final analysis to determine
      the fair values of Chart Bank's tangible and identifiable intangible
      assets and liabilities as of the completion date. Accordingly, the final
      purchase accounting adjustments and integration charges may be materially
      different from the pro forma adjustments presented in this document.
      Increases or decreases in the fair value of the assets and liabilities of
      Chart Bank as compared to the information shown in this document may
      change the amount of the purchase price allocated to goodwill and other
      assets and liabilities and may impact the statement of income due to
      adjustments in yield and/or amortization of the adjusted assets or
      liabilities.

      The unaudited pro forma condensed combined financial information presented
      in this document does not necessarily indicate the results of operations
      or the combined financial position that would have resulted had the merger
      been completed at the beginning of the applicable period presented, nor is
      it indicative of the results of operations in future periods or the future
      financial position of the combined company.

      PRO FORMA ADJUSTMENTS

      The unaudited pro forma condensed combined financial information for the
      merger includes the pro forma balance sheet as of December 31, 2004
      assuming the merger was completed on December 31, 2004. The pro forma
      statement of income for the year ended December 31, 2004 was prepared
      assuming the merger was completed on January 1, 2004. The pro forma
      adjustments included in the unaudited pro forma condensed combined
      financial information are as follows:

      (1)   Shows the effect of the mutual-to-stock conversion of Benjamin
            Franklin Bancorp, with gross proceeds of $55.8 million, offering
            expenses of $2.1 million, a contribution to the Benjamin Franklin
            Bank Charitable Foundation of $4.0 million of common stock, the
            establishment of an employee stock ownership plan that is in the
            process of acquiring, in the open market, 478,194 shares
            representing 8% of the shares issued in the conversion (including
            shares contributed to the Benjamin Franklin Bank Charitable
            Foundation), and the stock-based incentive plan that is expected to
            acquire 4.0% of the number of shares issued in the offering
            including the shares issued to the Benjamin Franklin Bank Charitable
            Foundation (239,097 shares). It is assumed that Benjamin Franklin
            Bancorp will purchase shares in the open market, for grant as
            restricted stock under the stock-based incentive plan, after
            receiving stockholder approval to adopt the plan. Future open market
            purchases by the employee stock ownership plan and stock-based
            incentive plan are assumed at $10.30 per share, the closing bid
            price of the stock on June 14, 2005. As of June 14, 2005, the
            employee stock ownership plan has purchased 300,000 shares at an
            average cost of $10.15 per share. The reduction in retained earnings
            reflects the one-time expense of funding the Benjamin Franklin Bank
            Charitable Foundation net of a deferred tax asset.

      (12)  Reflects the difference between market values and net book values of
            securities held to maturity acquired in the acquisition.

      (13)  Yield adjustment to reflect the difference between portfolio yields
            and market rates as of April 4, 2005 for loans acquired in the
            acquisition. Yield adjustments were calculated using present value
            analysis as follows: (a) the acquired loan portfolio was segregated
            into pools of similar loans; (b) cash flow projections were prepared
            for each loan pool based interest rates, balances, remaining terms
            to maturity, and estimated prepayment speeds for each pool; (c) cash
            flows were discounted to present value using risk adjusted discount
            rates for comparable loans; and (d) the resulting difference between
            the present value of future cash flows for each pool and the
            corresponding principal balance was the yield adjustment. Yield
            adjustments on acquired loans are amortized into interest income
            using the interest method over the estimated lives of the acquired
            loans.

            between the current portfolio balance for borrowings and the present
            value of projected cash flows related to the borrowings discounted
            using current market rates. Current market rates were based on rates
            offered by the Federal Home Loan Bank of Boston as of April 4, 2005.
            The yield adjustment for borrowings will be amortized into expense
            using the interest method over the lives of the acquired borrowings

            178,194 shares to be purchased will be acquired at a cost of $10.30,
            the closing bid price of the stock on June 14, 2005. The loan taken
            down by the employee stock ownership plan will be amortized over 30
            years on a straight-line basis. The employee stock ownership plan
            expense shown reflects the estimated amortization expense on a
            pretax basis for the period shown. Benjamin Franklin Bancorp also
            intends to adopt a stock-based incentive plan that will award shares
            of restricted stock in the amount of 4.0% of the number of shares
            issued in the offering, including the shares issued to the Benjamin
            Franklin Bank Charitable Foundation (a total of 239,097 shares). The
            shares expected to be granted under the stock-based incentive plan
            as restricted stock are assumed to be purchased in the open market
            after receiving stockholder approval for the plan. Open market
            purchases for the stock-based incentive plan are assumed at $10.30
            per share, the closing bid price of the stock on June 14, 2005. Also
            under the stock-based incentive plan, Benjamin Franklin Bancorp
            intends to grant options to purchase 10.0% of the number of shares
            issued in the offering, including shares issued to the Benjamin
            Franklin Bank Charitable Foundation. Adjustments to record estimated
            stock-based incentive plan expenses, including expenses of the
            restricted stock awards and option grants, and interest income to be
            earned on net proceeds of the offering, will be recorded as
            incurred. Since these estimates are non-recurring, they are not
            reflected in the calculations of pro forma income. Further, no
            expenses are included for the shares issued to the Benjamin Franklin
            Bank Charitable Foundation or other merger-related charges, all of
            which are one-time expenses. Employee stock ownership plan shares
            are assumed to be released at $10.30 per share, the closing bid
            price of the stock as of June 14, 2005. Taxes are calculated on an
            assumed marginal rate of 36.0%.

      (25)  The expense of the employee stock ownership plan represents the
            number of shares to be released to participants (15,940 shares per
            year) times the average price of the stock for the year (assumed to
            be $10.30 per share).

      (26)  Chart Bank operating results for the year ended December 31, 2004
            include $637,000 of merger-related expenses.

            to the acquisition of Chart Bank for a price of $30.75 per share in
            cash and newly issued common stock.

      (28)  Adjustment to interest income is the accretion of the discounts on
            the Chart Bank loans and investment securities resulting from
            purchase accounting. Accretion of the loan discount in the first
            year is estimated to amount to $513,000. Accretion of the discount
            on investment securities is estimated at $377,000 in the first year
            following the acquisition. Adjustments to record estimated interest
            income to be foregone as a result of funding the cash portion of the
            merger consideration paid to stockholders of Chart Bank and the
            expense of the acquisition will be recorded as incurred. Since these
            estimates are non-recurring, they are not reflected in the pro forma
            income statement
