          NOTE
          5 – Share-Based
          Payments
         
          In
          March 2008, the Company’s shareholders approved the
          2008 Stock Incentive Plan which will be utilized to
          provide equity opportunities and performance–based
          incentives to attract, retain and motivate those persons
          who make (or are expected to make) important
          contributions to the Company.  A total of
          2,000,000 shares are available for issuance under this
          plan. As of June 30, 2012, 761,932 shares had been
          granted under the plan, of which 150,000 shares were in
          the form of stock options and the remainder were in the
          form of restricted stock or other share
          grants. 
          Stock
          Options
         
          Under
          the Company’s previous share based long-term
          incentive compensation plan, the 1997 Stock Option Plan,
          the Company granted non-qualified stock options to
          employees.  There are no shares available for
          grant under this plan which expired on December 31,
          2006.  Options issued under this plan expire 10
          years after the date of grant and generally vested 1/36
          per month, with full vesting after three years. Under the
          Company’s 2008 Stock Incentive Plan, options issued
          expire 10 years after the date of grant and vest 1/36 per
          month, with full vesting after three years. The Company
          did not grant any options during the three or nine months
          ended June 30, 2012 or 2011.
         
        Compensation
        expense is recognized only for share-based payments
        expected to vest. The Company estimates forfeitures at the
        date of grant based on historical experience and future
        expectations. Stock compensation expense related to options
        for the three and nine months ended June 30, 2012, was
        approximately $15,000 and $60,000, respectively, and
        $23,000 and $68,000 for the three and nine months ended
        June 30, 2011, respectively.
       
        During
        the nine months ended June 30, 2012, 193,750 stock options
        were exercised using the cashless exercise option available
        under the plan which entitled the holder to 116,915 shares
        of common stock.  The intrinsic value of the
        options exercised was $510,000.  There was no
        realized tax benefit from options exercised for the nine
        months ended June 30, 2012, based on the “with and
        without” approach.  No stock options were
        exercised during the three and nine months ended June 30,
        2011.
       
        The
        following table summarizes the stock options outstanding
        and exercisable at June 30, 2012:
       
 
          The
          aggregate intrinsic value in the table above is before
          income taxes, based on the closing price of the
          Company’s common stock of $5.87 per share as of the
          last business day of the period ended June 30,
          2012.  As of June 30, 2012, the Company had no
          unrecognized compensation expense relating to outstanding
          stock options as all outstanding stock options were fully
          vested.  The deferred tax asset and realized
          benefit from stock options exercised and other
          share-based payments for the periods ended June 30, 2012
          and 2011, was not recognized, based on the
          Company’s election of the “with and
          without” approach.
         
        Restricted
        Stock
       
        The
        Company issues restricted stock to employees, directors and
        consultants. Such issuances may have vesting periods that
        range from one to three years or the issuances may be
        contingent on continued employment for periods that range
        from one to three years.  In addition, the
        Company has issued stock awards to certain employees that
        contain vesting provisions or provide for future issuance
        contingent on continued employment.
       
        The
        Company granted a total of 54,750 shares of restricted
        stock or shares issuable pursuant to promises to issue
        shares of common stock during the nine months ended June
        30, 2012. The fair value of the awards granted was
        approximately $227,000. All such shares of restricted stock
        vest and all such shares must be issued pursuant to
        promises to issue common stock in  September 2012
        through September 2014, provided the grantee has not
        voluntarily terminated service or been terminated for cause
        prior to the vesting or issuance date. There were 2,500
        restricted stock forfeitures during the three and nine
        months ended June 30, 2012.
       
        The
        Company granted a total of 288,750 shares of restricted
        stock or shares issuable pursuant to promise to issue
        shares of common stock during the nine months ended June
        30, 2011.  The fair value of the awards granted
        was approximately $1,657,000.  All such shares of
        restricted stock vest and all such shares must be issued
        pursuant to promise to issue stock between September 2011
        and December 2013, provided the grantee has not voluntarily
        terminated service or been terminated for cause prior to
        the vesting or issuance date. 2,500 shares of restricted
        stock were forfeited during the nine months ended June 30,
        2011.
       
        The
        Company recognized share-based compensation expense for
        restricted stock or promises to issue shares of common
        stock of approximately $189,000 and $596,000 for the three
        and nine months ended June 30, 2012, respectively, $178,000
        of which was included in accrued expenses at June 30, 2012,
        since the related shares have not been issued. Share-based
        compensation expense for restricted stock or promises to
        issue shares of common stock for the three and nine months
        ended June 30, 2011 was approximately $200,000 and
        $503,000, respectively, of which $155,000 was included in
        accrued expenses at June 30, 2011.  This expense
        is included in operating expenses for those respective
        periods. As of June 30, 2012, there was approximately
        $720,000, representing approximately 131,000 unvested
        shares, of unrecognized compensation cost related to
        non-vested restricted stock compensation arrangements
        granted under the incentive plans.  This
        unrecognized cost will be recognized over the weighted
        average period of the next 1.24 years.
       
        Common
        Stock Purchase Warrants
       
        At
        June 30, 2012, 80,000 warrants issued in connection with
        investor relations were outstanding and
        exercisable.  The warrants have an exercise price
        of $1.30 per share, remaining life of 4.04 years and
        aggregate intrinsic value of approximately
        $366,000.  The aggregate intrinsic value is
        before taxes, based on the closing price of the
        Company’s common stock of $5.87 per share on the last
        business day of the period ended June 30, 2012.
       
        No
        warrants were issued in the nine months ended June 30, 2012
        or 2011.
       
        There
        were no warrant exercises in the nine months ended June 30,
        2012 or 2011.  There is no unrecognized
        compensation cost related to warrants as of June 30,
        2012.
