              PRO FORMA COMBINED CONSOLIDATED FINANCIAL INFORMATION

         The following unaudited pro forma combined condensed consolidated
balance sheet combines the consolidated historical balance sheets of Peoples
Heritage Financial Group, Inc. ("Peoples Heritage") and Banknorth Group, Inc.
("Banknorth"), assuming the merger of Banknorth with and into Peoples Heritage
was consummated as of December 31, 1999 on a pooling of interests accounting
basis, and the following unaudited pro forma combined condensed consolidated
statements of operations present the combined consolidated statements of
operations of Peoples Heritage and Banknorth assuming the merger was consummated
as of the beginning of the indicated periods. Certain insignificant
reclassifications have been reflected in the pro forma information to conform
statement presentations.

         The effect of an expected reorganization and restructuring charge in
connection with the merger has been reflected in the pro forma combined
condensed consolidated balance sheet; however, because the reorganization and
restructuring charge is nonrecurring, it has not been reflected in the pro forma
combined condensed consolidated statements of operations. The pro forma
financial data does not reflect cost savings, revenue enhancements and other
operating synergies which are expected to be realized after the merger is
completed.

         The pro forma information presented is not necessarily indicative of
the results of operations or the combined financial position that would have
resulted had the merger been consummated at December 31, 1999 or at the
beginning of the periods indicated, nor is it necessarily indicative of the
results of operations in future periods or the future financial position of the
combined entities.

         The pro forma information should be read in conjunction with the
historical consolidated financial statements of Peoples Heritage and Banknorth,
including the related notes.

        Notes to Pro Forma Combined Condensed Consolidated Balanced Sheet

         (1) Reflects an estimated $31 million, net of taxes, of reorganization
and restructuring charges related to the merger. Additionally, in the first
quarter of 2000, Peoples Heritage recorded $1 million, net of taxes, of special
charges related to branch closings and Banknorth recorded $2 million, net of
taxes, of special charges related to write-downs of a facility held for sale and
auto lease residuals. In the second quarter of 2000, Peoples Heritage also
expects to record approximately $10 million, net of taxes, in securities losses
to restructure the combined investment portfolio. These items are not included
in the above pro forma financial statements.

         (2) Reflects the par value of the Peoples Heritage common stock to be
issued in exchange for Banknorth common stock in connection with the merger,
with related adjustments to paid-in capital. The Peoples Heritage common stock
to be issued in connection with the merger was calculated by multiplying the
number of outstanding shares of Banknorth common stock as of December 31, 1999
by the 1.825 exchange ratio and adding the number of shares of Peoples Heritage
common stock issuable or potentially issuable prior to the effective time of the
merger, based on the 1.825 exchange ratio, with respect to the Banknorth common
stock equivalents which were outstanding on such date.

   Note to Pro Forma Combined Condensed Consolidated Statements of Operations

          (1) Peoples Heritage expects to achieve cost savings, revenue
enhancements and other operating synergies following consummation of the merger.
The cost savings, revenue enhancements and other operating synergies are
expected to be achieved in various amounts at various times during the periods
subsequent to consummation of the merger and not ratably over or at the
beginning or end of such periods. No adjustment has been reflected in the pro
forma combined statements of operations for the anticipated cost savings,
revenue enhancements and other operating synergies.

          For the reasons noted above, it should not be assumed that the
dilution in Peoples Heritage earnings per share reflected in the pro forma
combined condensed consolidated statements of operations will represent actual
dilution with respect to the merger.
