Summary A merger of complementary franchises and skill sets Long term partnership, exciting growth and expansion potential Significant synergy & efficiency opportunities Increased stakeholder value - staff, customers and shareholders

Gary Kennedy Group Director, Finance & Enterprise Technology, Allied Irish Banks, p.l.c.

Background AIB has a long and successful track record in U.S. regional banking Highly valuable franchise, excellent market positions Slowing revenues in recent years Changed approach, adopting a Community Banking model in retail markets Continuing commitment to full service commercial banking

Commitment to U.S. regional banking Exit not a credible consideration, founded on key fundamentals: conviction in our ability to generate long term shareholder value in U.S.; U.S. regional banking - high performers generate high growth; franchise potential under exploited; AIB retail and commercial banking skills under utilised.

Long term partnership - key criteria Detailed examination of alliance / partnership opportunities to increase value for shareholders Common values, ethos and culture AIB skill sets fully utilised Proven and consistent performance record Management depth, community and commercial banking skills Convincing capacity to integrate and accelerate Allfirst's changed business model Combined market scale and power, sustainable growth proposition.

M&T - The ideal choice Quality of management team demonstrated over long period Fully satisfies other key criteria Close alignment of AIB / M&T management interest, underpinned by combined shareholding Positioning for earnings growth in line with other AIB franchises Improved transparency and increasing value of AIB's investment: enlarged franchise a potential member of S&P 500 index.

Expected AIB earnings impact Expected to be modestly accretive in 2003 based on: Income from associated undertakings in 2003 assumes marginal organic growth in "Allfirst", market consensus growth of 7% in "M&T" net income Share of $100 million cost savings ($60 million in 2003) Approx. $450m to be utilised for share buyback

Investing for sustainable growth Convincing shareholder proposition Merger of two complementary franchises with increased scale and synergy opportunities Strong track record of M&T in relatively low growth locations Significant increase in management depth and capability Shared community and commercial banking ethos

Transaction Financials Based on "Street" estimates for M&T and marginal growth in the Allfirst businesses, the transaction is expected to be accretive to M&T's cash earnings per share beginning in 2003 Accretion is principally driven by expense savings estimated at 17.4% of Allfirst's annualized 2002 non-interest expense base. Cost savings are expected to begin shortly following closing and be fully implemented by 2004. Total expense savings are estimated to be $60 million in 2003 and just over $100 million in 2004. Revenue enhancements identified but not assumed. M&T fully expects to continue to manage it's capital to balance prudent capital levels while remaining dedicated to superior shareholder returns. The cash component of merger consideration is assumed to be financed through a mix of subordinated and senior debt.
