Legal and U.S. Regulatory Proceedings On March 2, 2001, the Company became aware of environmental contamination resulting from an unknown heating oil leak at its former manufacturing facility. The Company immediately notified the New Jersey DEP and the local authorities, and hired a contractor to assess the exposure and required clean up. The total estimated costs for the clean-up and remediation is $739,000, of which approximately $63,000 remains accrued as of December 31, 2011.

There is a possibility, however, that the remediation costs may exceed the Company’s estimates. The restricted cash on the Consolidated Balance Sheet of $54,000 as of December 31, 2011 and 2010 represents a restricted escrow account set up on the requirement of the NJ DEP for the soil remediation work.

In response to an observation by the New Jersey DEP of pesticide contamination in a portion of its property located at 105 Lincoln Avenue in Buena, New Jersey, the Company contracted with an environmental and remediation firm to complete soil delineation of the pesticide contamination, its remediation and disposal. The remediation and disposal was completed in 2011 at a cost of approximately $61,000. The Company received a “No Further Action Letter” from the New Jersey Department of Environmental Protection on May 23, 2011.
