  12.  LIQUIDITY
 
  At
  December 31, 2011, the Company had cash and cash equivalents
  of $1.6 million and a working capital deficit of
  $3.1 million, or $2.1 million excluding deferred
  revenue.  Despite this working capital deficit, the
  Company believes that its existing internal liquidity, supported
  by cash on hand and cash flows from operations should be adequate
  to fund normal business operations and address its financial
  commitments for at least the next 12 months, assuming no
  significant unforeseen expense or further revenue
  decline.  If the Companys foregoing beliefs or
  assumptions prove to be incorrect, however, the Companys
  business, results of operations and financial condition could be
  materially adversely affected.
