  Think we’ve put together a regional powerhouse in the northeast
 
  Combined entity will have $30 billion in assets , $20 billion in deposits and will become the 25th largest bank in the entire country
 
  Have a great distribution network of over 340 branches across the most populated states in New England
 
  NewAlliance ‘s footprint is contiguous to our New York state footprint — in fact, drive time from our regional center in Albany to Hartford is about an hour shorter that our Buffalo to Pittsburgh commute
 
  Cleary this is a case where the whole is greater than the sum of its parts as two very vibrant, growing franchises coming together in a partnership that will help springboard the growth of the combined entity past what we could have done individually

Strong Strategic Fit Committed to shareholder value Customer-centric and relationship focused Local decision-making Flexible model to meet the growing needs of customers Strong brand alignment Deep community relationships 12

Furthermore, we believe the combination of the companies will create a dynamic and dominant regional bank in the Northeast that is differentiated from competitors. The combined entity offers shareholders the potential for industry-leading returns. Our commonality includes:

  Based on this pricing and assumptions?
    Nicely accretive in 2010, improving to mid-teens in 2011 — first full year of operation
 
    Very strong internal rate of return
 
    Only modestly dilutive to TBV with rapid earn-back
 
    Strong pro-forma capital ratios — inclusive of the PNC facility
    Maintain TCE/TA in upper end of our range
 
    TRBC in excess of well-capitalized levels — close to 11%
    Excludes benefit of hold co liquidity of $100mm
 
    Excludes effect of loan marks
    Which if added back to regulatory capital for both NCC / HNC
 
    Move this ratio in a material way — above 12%
 
    Why would we do that?
 
    Marks reduce risk of loans — either you count mark as capital or lower the risk weighting on loans
 
    Either way — risk based capital improves

25 The Company believes that these measures are useful to management and investors because they permit a more effective evaluation and comparison of the Company's results and performance in relation to its ongoing operations. First NiagaraBeginning in Q2 2010, the impact of income taxes on these nonrecurring items was calculated using the effective tax rate for the quarter.2010 - Q2: After-tax noninterest expense: Harleysville acquisition related expenses of $ 18.8 million, $5.6 million charitable contribution related to the acquired markets and severance and related costs of $0.5 million. Q1: After-tax noninterest expense: Harleysville acquisition related expenses of $3.7 million. 2009 - Q2: After-tax noninterest expense: FDIC's special assessment charge of $3.3 million based on each insured depository institution's assets less Tier 1 Capital. Also includes expenses related to the National City branch acquisition of $1.4 million.2009 - Q2: Also includes accelerated discount accretion of $7.7 million resulting from the redemption of preferred stock purchased by the U.S. Treasury Department under the Troubled Asset Relief Program and $1.7 million of accrued dividends and preferred stock discount accretion through the redemption date. Reported(GAAP) net income was $20.0 million for the second quarter of 2010, $28.9 million for first quarter of 2010 and $20.8 million for the second quarter of 2009. Reported(GAAP) return on average assets(ROAA) for the second quarter of 2010 was 0.41%.NewAlliance2010 - Q2: After-tax noninterest revenue: Gain on limited partnership of $1.7 million. Q1: Tax-exempt life insurance proceeds of $2.6 million.2009 - Q2: After-tax noninterest expense: FDIC's special assessment charge of $2.6 million based on each insured depository institution's assets less Tier 1 Capital. Reported(GAAP) net income was $16.3 million for the second quarter of 2010, $16.4 million for first quarter of 2010 and $10.1 million for the second quarter of 2009. Reported(GAAP) ROAA for the second quarter of 2010 was 0.76%. Notes to Slide 9: Non-GAAP/operating results excludes certain non-recurring items


 

26 • Under the terms of the merger agreement, the aggregate consideration payable to NewAlliance stockholders in the merger as of the signing date is allocated 14% in cash and 86% in First Niagara common stock. The cash consideration pool is equal to $210,070,888 (subject to certain adjustments), and the stock consideration pool is 99,403,291 shares of First Niagara common stock (subject to certain adjustments). • Each NewAlliance stockholder can elect to receive, for each NewAlliance share owned by such stockholder, either 1.10 shares of First Niagara stock or $14.28 in cash, subject to adjustment, election and allocation procedures spelled out in the merger agreement. NewAlliance stockholders may make a mixed election of stock and cash for their shares, subject to the adjustment, election and allocation procedures. • The per share cash price of $14.28 and the exchange ratio for the stock portion of the consideration are fixed. As a result, the per share value of the stock consideration will fluctuate prior to closing due to fluctuations in the price of First Niagara stock. The current per share value of the stock consideration, based upon First Niagara's closing stock price on August 18, 2010, is $14.06 per share. At closing, the per share cash value and the per share stock value are likely to be different. • The cash consideration pool of $210,070,888 (subject to certain adjustments), if allocated equally to all shares of NewAlliance common stock, equals approximately $2.00 per share of NewAlliance common stock, based on the current number of NewAlliance common shares outstanding. The current per share value of the stock consideration, if allocated equally to all shares of NewAlliance common stock, based upon First Niagara's closing stock price on August 18, 2010, is $12.09 per share. Accordingly, the per share merger consideration, on a blended basis and based upon First Niagara's closing stock price on August 18, 2010, equals $14.09 ($2.00 plus $12.09). • First Niagara common stock may be issued to NewAlliance stockholders who make cash elections if the cash pool is oversubscribed, and cash may be issued to NewAlliance stockholders who make stock elections if the stock pool is oversubscribed. It is likely that all NewAlliance stockholders will receive a mix of cash and stock consideration in the merger. The allocation of the mix of consideration payable to NewAlliance stockholders in the merger will not be known until First Niagara tallies the results of the cash/stock elections made by NewAlliance stockholders, which will not occur until near or after the closing of the merger.• Assuming satisfaction of all necessary conditions to closing, election forms will be mailed to NewAlliance stockholders no more than 40 and no less than 20 business days prior to the anticipated closing of the merger (unless otherwise agreed by the parties). The election form will be accompanied by instructions for its completion, and a deadline for submission of election forms will be specified in the instructions. NewAlliance stockholders are urged to carefully read and follow the instructions for completion of the election form and to submit the form in advance of the election form deadline. NewAlliance stockholders who do not submit an election form by the deadline, or who improperly complete an election form, will not be entitled to elect the form of consideration applicable to their shares, and will receive cash, stock or a mix of cash and stock, subject to the adjustment, election and allocation procedures.
