Investment Thesis

PBCT’s strong capital position and disciplined emphasis on credit performance provide an important measure of safety in the current environment.

The ability to leverage the capital raised in 2007 positions us well for future expansion.

Why own People’s United? …

Strong balance sheet with significant capital surplus

Exceptional credit quality

Significant and very low cost deposit market share

Committed to maximizing long-term earnings power and shareholder value

5

Investment Thesis

Our focus on long-term earnings optimization translates into:

Things we do:

Continue to focus on self-originated middle market commercial loans while retaining our underwriting discipline

Continue to use our securities & short-term investments portfolio solely as a temporary store of excess capital, while not stretching for temporary spread income

Remain primarily funded with equity and deposits

Strive to keep our expense structure lean

Remain vigilant as we explore acquisition opportunities, to ensure any deal improves long-term earnings and shareholder value

Things we don’t do:

Originate sub-prime or Alt-A loans

Originate option ARMs, negative amortization loans, or teaser-rate loans

Have SIV exposure or CDOs on the balance sheet

Make high-risk structured investments

Leverage the balance sheet using wholesale funding to purchase loans or securities (no carry trade)

While we remain committed to achieving a lower efficiency ratio, this will take time given:

Lower interest income from our excess capital in the current rate environment

The long-term displacement of investment securities with loans, which has eliminated any carry trade

21

Acquisition Strategy

We continue to feel properly priced, opportunistic acquisitions can significantly enhance shareholder value, assuming the following:

Commercially-oriented franchises with a strong core deposit base

Attractive markets of the Northeast United States, including contiguous, in-market and new markets

Ability to leverage PBCT excellent credit standards

Generate an IRR approaching 20%

22

Conclusion

People’s United remains committed to continuing to increase shareholder value

Shareholders are protected by continued strength in underwriting and asset quality

Significant capital reserves will be used primarily to fund future growth

Management is aligned with shareholders

Will continue to maintain focus on driving financial performance
