9.    POST-RETIREMENT BENEFITS

Effective January 1, 1992, we adopted the Outside Directors’ Retirement Plan which provides that each non-employee director, upon resignation from the Board of Directors after reaching the age of 65, will receive a lump sum cash payment equal to $5,000 for each full year of service as a director of the Company (and its predecessors and successors) up to $50,000. The plan was terminated in 2011.  At December 31, 2012 and 2011, we have accrued $150,000 in other current liabilities in the Consolidated Balance Sheets for future payments that were earned under the plan before it was terminated.
