<F1>
In September 1995, the Company changed its balance sheet classification of
customer service contracts, which resulted in a restatement of previously
reported assets and liabilities.  There was no impact on the statement of 
operations for the fiscal year 1994 or on retained earnings.
<F2>
The Company also holds a long-term receivable debt security of $4,988 which
is reported as a non current asset.
