Acquisitions</i></b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>NewAlliance Bancshares, Inc.</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">On April 15, 2011, the Company acquired all of the outstanding common shares of NewAlliance Bancshares, Inc. (“NewAlliance”), the parent company of NewAlliance Bank, in a transaction totaling $1.5 billion, and thereby acquired NewAlliance Bank’s 88 branch locations across eight counties from Greenwich, Connecticut to Springfield, Massachusetts. The merger with NewAlliance enabled us to expand into the New England market, improve our core deposit base, and add additional scale in our banking operations. Under the terms of the merger agreement, as amended, each outstanding share of NewAlliance stock was converted into the right to receive either 1.10 shares of common stock of the Company, or $14.28 in cash, or a combination thereof. As a result, NewAlliance stockholders received 94 million shares of First Niagara Financial Group, Inc. common stock, valued at $1.3 billion based on the $14.00 closing price of the Company’s stock on April 15, 2011, and cash consideration of $199 million. Also under the terms of the merger agreement, NewAlliance employees became 100% vested in any NewAlliance stock options they held and these options converted into options to purchase Company common stock. These options had a fair value of $16 million on the date of acquisition. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">Direct costs related to the NewAlliance acquisition were expensed as incurred. During the three months ended March 31, 2011, we incurred $6.0 million in merger and acquisition integration expenses related to the NewAlliance transaction, including $0.7 million in salaries and benefits, $0.4 million in technology and communications, $0.3 million in occupancy and equipment, $1.0 million in marketing and advertising, $2.4 million in professional services, and $1.2 million in other noninterest expenses. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">We are still evaluating the estimated fair values of the assets acquired and liabilities assumed. Accordingly, the amount of any goodwill to be recognized in connection with this transaction is also yet to be determined. The results of NewAlliance’s operations will be included in our Consolidated Statement of Income after April 15, 2011, the date of acquisition. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Harleysville National Corporation</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">On April 9, 2010, the Company acquired all of the outstanding common shares of Harleysville National Corporation (“Harleysville”), the parent company of Harleysville National Bank and Trust Company, and thereby acquired Harleysville National Bank and Trust Company’s 83 branch locations across nine Eastern Pennsylvania counties including $1.1 billion in cash, loans with a fair value of $2.6 billion, and core deposit intangible of $42 million, as well as deposits with a fair value of $4.0 billion, and borrowings with a fair value of $960 million. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">Under the terms of the merger agreement, Harleysville stockholders received 0.474 shares of First Niagara Financial Group, Inc. common stock in exchange for each share of Harleysville common stock, resulting in our issuance of 20.3 million common shares of Company common stock with an acquisition date fair value of $299 million. Also under the terms of the merger agreement, Harleysville employees became 100% vested in any Harleysville stock options they held. These options had a fair value of $1 million on the date of acquisition. The merger with Harleysville enabled us to expand into the Eastern Pennsylvania market, improve our core deposit base, and add additional scale in our banking operations. The results of Harleysville’s operations are included in our Consolidated Statements of Income from the date of acquisition. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="left" style="font-size: 10pt; margin-top: 10pt"><b>Other</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt">As part of our plan to enhance our risk management operations, workforce, and products and services to benefit customers in our newly added New England market, on April 15, 2011, we acquired Pierson & Smith, an insurance brokerage, consulting and third party administration firm in Norwalk, Connecticut. In an effort to expand our risk management and employee benefits consulting services to our Pennsylvania markets, we acquired several insurance agencies in 2010. In August 2010, we acquired RTI Insurance Services, Inc. and Three Rivers Financial Services, Inc., in November 2010, we acquired Summit Insurance Group Inc. and Summit Benefits, LLC, and in December 2010, we acquired Banyan Consulting, LLC.
