Forward Looking Information
- --------------------------------------------------------------------------------

This presentation contains forward looking statements with respect to the
financial condition, results of operations and business of M&T Bank Corporation
("M&T") and Keystone Financial, Inc. ("Keystone") and assuming the consummation
of the transaction, a combined M&T and Keystone, including statements relating
to: (i) the cost savings and revenue enhancements and accretion to reported and
cash earnings that will be realized from the merger; and (ii) the restructuring
charges expected to be incurred in connection with the merger. These forward
looking statements involve certain risks and uncertainties. Factors that may
cause actual results to differ materially from those contemplated by such
forward looking statements include, among other things, the following
possibilities: (i) expected cost savings from the merger cannot be fully
realized or realized within the expected time; (ii) revenues following the
merger are lower than expected; (iii) competitive pressure among depository
institutions increase significantly; (iv) the integration of the business of M&T
and Keystone costs more, takes longer or is less successful than expected; (v)
the cost of additional capital is more than expected; (vi) changes in the
interest rate environment reduces interest margins; (vii) general economic
conditions, either nationally or in the states in which the combined company
will be doing business, are less favorable than expected; (viii) legislation or
regulatory requirements or changes adversely affect the business in which the
combined company will be engaged; and (ix) changes may occur in the securities
market. Neither M&T nor Keystone assume any obligation to update forward looking
statements.

A Logical Franchise Extension
- --------------------------------------------------------------------------------

o    Logical geographic extension of M&T's strong New York franchise

     / /  Already #1 in deposit market share in Upstate New York, pro forma M&T
          would also rank #1 in Central Pennsylvania

          -    Combined geographic area of Upstate New York and Central
               Pennsylvania would rank as the 10th largest U.S. state in terms
               of total deposits

     / /  Ability to leverage M&T's proven New York super-community banking
          strategy across Keystone's franchise

     / /  Familiarity with these markets

          -    Existing M&T presence through the ONBANCorp acquisition

          -    Similar demographics

          -    M&T has proven that it can generate top-tier performance and
               growth in these markets

     / /  Increases scale of banking franchise

     / /  Complementary business models

          -    New small business and middle market lending opportunities for
               M&T

          -    Enhances M&T's Trust and Investment Services business, adding
               $3.3 billion in assets under management, including $1.2 billion
               in mutual funds


                                                                        Keystone

- --------------------------------------------------------------------------------
Low Level of Operational Risk
- --------------------------------------------------------------------------------

o    Proven integration experience at M&T under the current management team

o    History of delivering and even exceeding on projections at M&T:

     / /  Exceeded the EPS projection made at announcement in the ONBANCorp
          transaction by 4%

     / /  One of only 6 banks to do so out of 27 total banks who have announced
          deals greater than $850 million in value since 1995

     / /  In the 17 quarters since 1995, M&T has exceeded the consensus First
          Call quarterly estimates by an average of 2% per quarter

o    Only the third largest deal announced by M&T on a relative basis

o    Integration will be facilitated by KSTN's 1999 consolidation of its banks
     under a single charter

o    Minimal business disruption expected given no branch overlap


                                                                        Keystone

- --------------------------------------------------------------------------------
Financially Attractive with Straightforward, Conservative Assumptions
- --------------------------------------------------------------------------------

     o    Had the deal been accounted for as a pooling, it would have been
          accretive in the first full year

     o    As structured, the transaction is accretive to cash EPS in the first
          full year

     o    Favorably priced relative to comparable transactions

     o    Generates an internal rate of return ("IRR") well in excess of M&T's
          cost of equity capital

     o    Financing mix is shareholder focused:

          / /  Blended cost of capital has been minimized

          / /  Cash flow per share is significantly improved compared to a
               pooling deal

     o    No revenue enhancements have been assumed, but opportunities have been
          identified

                                                                        Keystone
