Cirucci, President and Chief Executive Officer of the Company, stated that the "Company's strong capital position and profitability continue to afford the Board with the ability to enhance shareholder value through the payment of cash dividends. In addition, we are also pleased to announce that Alliance Bank is currently the largest community bank located in Delaware County, Pennsylvania as well as the sixth largest depository institution in Delaware County as reported by the FDIC in their recently released deposit share statistics as of June 30, 2007." The Company's total assets increased $12.0 million or 2.9% to $422.3 million at September 30, 2007 as compared to $410.3 million at December 31, 2006.

The Company is the recently formed "mid-tier" holding company for Alliance Bank and is 55% owned by Alliance Mutual Holding Company and 45% owned by public shareholders. A principal reason for the formation of the Company was to facilitate the ability to repurchase shares without adverse tax consequences. The Company has continued its effort to request that the Office of Thrift Supervision ("OTS"), the Company's primary federal regulator, authorize the repurchase of up to 159,300 shares of common stock (4.9% of the shares held by the public) in the open market. While the OTS has a general policy prohibiting the repurchase of shares within one year of formation of a new mutual holding company and subsidiary stock offering, the Company has asked that the one year restriction not be applied to its recent formation since Alliance Bank has operated in the mutual holding company structure for more than one year. No assurance can be given that the OTS will permit or authorize share repurchases by the Company within one year of its formation. Alliance Bancorp, Inc. of Pennsylvania is the holding company for Alliance Bank, a Pennsylvania chartered, FDIC-insured savings bank headquartered in Broomall, Pennsylvania. Alliance Bank operates nine full-service branch offices located in Delaware and Chester Counties, Pennsylvania. This news release contains forward-looking statements.
