HARLEYSVILLE NATIONAL CORPORATION REPORTS

THIRD QUARTER EARNINGS OF $6.6 MILLION

HARLEYSVILLE, PA (October 15, 2008) - Harleysville National Corporation (NASDAQ: HNBC) today reported net income of $6.6 million, or $.21 per diluted share, for the third quarter of 2008, compared to $7.2 million or $.25 per diluted share for the third quarter of 2007.  For the nine months ended September 30, 2008, net income was $21.3 million or $.67 per diluted share compared to $20.4 million or $.70 per diluted share during the comparable period in 2007.  Net income for the third quarter and year to date 2008 included pre-tax merger costs of $974,000, or $.02 per diluted share related to the acquisition of Willow Financial Bancorp, Inc. expected to close during the fourth quarter.  These charges include system conversion, integration consulting and severance expenses associated with the acquisition.  Harleysville expects to incur additional merger-related expenses in the fourth quarter of 2008.

Paul D. Geraghty, President and CEO, said, “Despite the difficult economic environment and the turmoil in the financial markets, Harleysville's third quarter performance was stable.  Earnings, excluding merger costs, were level on a sequential basis. Year over year loan and deposit growth was largely driven by a combination of organic loan growth of $111.7 million and deposit growth of $87.2 million along with the impact of the East Penn Financial acquisition, which closed in November 2007.”

 Mr. Geraghty continued, “While many banks and financial institutions are struggling to survive today, Harleysville is open for business for reasonable transactions with creditworthy relationships in our market territory.  We remain well-capitalized with good liquidity.  We continue to place significant effort on credit management and have increased resources to contend with the economy.”

Mr. Geraghty continued, “The acquisition of Willow Financial Bank continues to move forward, and earlier this month we received needed approvals from the Office of the Comptroller of the Currency.  The Office of Thrift Supervision has also not objected to the transaction, and we expect to receive approvals from the Federal Reserve Board and the Pennsylvania Department of Banking by the end of October.  Once those approvals are in place we will move quickly to close the transaction, and expect to accomplish this by early December 2008.”

Mr. Geraghty concluded, “We continue to move toward our strategic goals, however, there is no single initiative that will drive us there overnight.  With our continued focus on our three-fold strategy to drive improvement through expansion, empowerment, and effectiveness, we have derived multiple benefits.  The acquisition of Willow Financial is a key milestone in that regard.  With many of our larger competitors in Southeastern Pennsylvania experiencing dramatic changes, we believe that the market opportunity for a strong locally-headquartered community bank with the scale, market presence, and sophisticated product set of the combined Harleysville National/Willow Financial Bank will be significant.”

The following is an overview of the key financial highlights for the quarter:

·   Total assets were $3.9 billion at September 30, 2008, an increase of 16.8% from $3.4 billion at September 30, 2007.

·   Loans were $2.5 billion, an increase of 21.1% from $2.1 billion at September 30, 2007.  Deposits were $3.02 billion, up 18.6% from $2.54 billion last year.

·   Net interest income on a tax equivalent basis in the third quarter of 2008 increased $4.8 million or  21.6% from the same period in 2007 mainly as a result of a decrease in customer deposit costs and the East Penn acquisition as well as organic loan growth.  Third quarter net interest margin was 3.02%, increasing 14 basis points year over year and decreasing 4 basis points sequentially.

·   Nonperforming assets were $38.8 million at September 30, 2008.  Nonperforming assets as a percentage of total assets were 0.98% at September 30, 2008, compared to 1.01% at June 30, 2008 and 0.46% at September 30, 2007.  Net charge-offs were $2.1 million, compared to $1.5 million in the third quarter of 2007.  The allowance for credit losses increased to $31.7 million at quarter end, compared to $31.2 million at June 30, 2008, and $22.6 million at September 30, 2007.  Provision for loan losses increased to $2.6 million from $2.5 million during the third quarter of 2007.

 ● Noninterest income was $10.4 million during the quarter, an increase of 7.0% from $9.8 million in last year’s second quarter, driven by growth in service  charges on deposits of $964,000 partially offset by a decrease in wealth management income of $746,000.

        ● Noninterest expense was $25.2 million, an increase of 33.4% from $18.9 million in the third quarter of 2007, driven by the acquisition of East Penn, charges related to the upcoming merger with Willow Financial Bancorp as well as branch expansion. Occupancy expenses increased due to the addition of the East Penn branches as well as rent expense on the bank properties in the sale-leaseback transaction completed in the fourth quarter of 2007. Other expenses increased mostly due to additional professional and consulting fees, FDIC insurance assessments and the identifiable intangible asset amortization related to the East Penn acquisition.
