ITEM 2.01. COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS.

      On April 1, 2009, Penseco Financial Services Corporation, a Pennsylvania
corporation ("Penseco"), completed its acquisition of Old Forge Bank, a
Pennsylvania commercial bank ("Old Forge") in accordance with the Agreement and
Plan of Merger ("merger agreement") by and among Penseco, its direct
wholly-owned subsidiary, Penn Security Bank and Trust Company, a Pennsylvania
commercial bank and trust company ("Penn Security"), and Old Forge, pursuant to
which Old Forge, in a two-step transaction, merged with and into Penn Security,
with Penn Security continuing as the resulting institution (the "merger").

      As a result of the merger, Old Forge shareholders will receive an
aggregate of approximately $17.4 million in cash and 1,128,079 shares of Penseco
common stock. The value of the final merger consideration to be received by Old
Forge shareholders is approximately $102.28 per share of Old Forge common stock
based on the terms of the merger agreement, or approximately $56.9 million in
the aggregate based on the $35.00 per share last sale price of Penseco common
stock on March 31, 2009.

agreement and is qualified in its entirety by reference to the text of the
