Item 8.01. Other Events.

Orrstown Bank (the “Bank”), the wholly-owned banking subsidiary of Orrstown Financial Services, Inc. (the “Company”), is listed as a creditor holding an unsecured nonpriority claim on the Schedules filed by Yorktown Funding, Inc. (“Yorktown”) in its case for relief under Chapter 11 of the United States Bankruptcy Code filed in the United States Bankruptcy Court for the Middle District of Pennsylvania on February 9, 2010. The case is docketed at 1:10-bk-01042-MDF. At the time of the Yorktown Bankruptcy filing, the balance outstanding on the Yorktown Line of Credit was $8,598,216, which balance remains unpaid. Additional details were disclosed in the Company’s Current Report on Form 8-K, dated March 19, 2010, filed with the Commission on March 22, 2010.

The Bank has filed a proof of claim in the amount of its pre-petition claim and has taken an active role in the bankruptcy case. The Bank participated in the negotiation of all of the salient terms of Yorktown’s Plan of Reorganization. Yorktown has arranged for exit financing with the Bank, as lead bank, and several other financial institutions. The Yorktown Plan of Reorganization was filed on May 11, 2011. The Plan provides for payment in full of all existing claims, including the Bank’s claim, which will be paid in cash on the Effective Date of the Plan. The Effective Date is scheduled to be fifteen (15) days after entry of the Bankruptcy Court Order confirming the Plan. The Bank is cautiously optimistic that the Confirmation Date could occur before August 15, 2011.

As noted above, the Bank is participating in the exit financing for Yorktown. The exit financing will be secured by first-lien mortgages on residential manufactured, modular and site-built homes already owned by Yorktown, as well as a first-lien mortgage on additional real estate collateral provided by the guarantor. The total credit exposure to the Bank under the newly underwritten exit financing is $8,998,000. In addition to the exit financing, the Bank, as lead bank, and several other financial institutions will provide a credit facility to a newly formed entity, with related principles, to continue operations similar to that of Yorktown. Advances under the new facility are expected to be approximately $16,000,000 of which the Bank’s share is expected to be $7,800,000. These advances will be secured by a UCC-1 filing, recorded assignments of first-lien mortgages on the residential manufactured, modular and site-built homes, and the original promissory notes for loans originated by the newly formed entity with proceeds of the new credit facility.
