Income Taxes
 
No provision for Federal and state income taxes was required for the three months ended March 31, 2012 and 2011 due to the Company's operating losses and increased deferred tax asset valuation allowance.  At March 31, 2012 and December 31, 2011, the Company has unused net operating loss carry-forwards of approximately $57,150,000 and $55,394,000 which expire at various dates between 2021 and 2031.  Some of this amount may be subject to annual limitations under certain provisions of the Internal Revenue Code related to "changes in ownership."
 
As of March 31, 2012 and December 31, 2011, the deferred tax assets related to the aforementioned carry-forwards have been fully offset by valuation allowances, since significant utilization of such amounts is not presently expected in the foreseeable future.
