      Note
      4 – Retirement Plan
     
      The Company
      sponsors a defined contribution retirement savings plan with
      a cash or deferred arrangement (the “Plan”), as
      provided by Section 401(k) of the Internal Revenue Code
      (“Code”).  The Plan covers
      substantially all employees, who may elect to contribute a
      portion of their compensation to the Plan, subject to maximum
      amounts and percentages as prescribed in the
      Code.  Each calendar year, the Company’s
      Board of Directors (the “Board”) determines the
      portion, if any, of employee contributions that will be
      matched by the Company.  For calendar years 2011
      and 2010, the employer matching contributions represented an
      amount equal to 100% of the first 2% of employee
      contributions and 50% of the next 1% of employee
      contributions to the Plan.  If an employee
      separates from the Company prior to the full vesting of the
      funds in their account that represent the matching employer
      portion of their account, then the unvested portion of the
      matching employer portion of their account is forfeited when
      they take a distribution of their account.  The
      Company utilizes such forfeitures as an offset to the
      aggregate matching contributions.  The Company's
      matching contribution to the Plan, net of the utilization of
      forfeitures, was $153,000 and $141,000 for fiscal years 2012
      and 2011, respectively.
