Subsequent Events	NOTE P — SUBSEQUENT EVENTS During November 2011, we entered into a securities purchase agreement (the "Purchase Agreement") with one institutional investor pursuant to which we issued and sold a senior convertible note in the original principal amount of $10.0 million (the "Initial Note") and a warrant (the "Warrant") to purchase up to 1,302,083 shares of our common stock. Subject to the satisfaction of conditions set forth in the Purchase Agreement, we have the right to require the investor to purchase an additional senior convertible note in the original principal amount of up to $5.0 million (the "Additional Note," and, together with the Initial Note, the "Notes") on the six-month anniversary of the initial closing date. The indebtedness evidenced by the Notes bears interest at 8.0% percent per year, payable quarterly, and matures on the 30-month anniversary of the initial closing date. The Notes will amortize in equal monthly installments commencing on the eight-month anniversary of the initial closing date. The Notes may be converted into our common stock, at the option of the holder, at any time following issuance, with respect to the Initial Note, or at any time following six months after the date of issuance, with respect to the Additional Note. The initial conversion price of the Initial Note is $3.74, subject to adjustment as provided in the Initial Note. On the six-month anniversary of the initial closing date, the conversion price applicable to the Initial Note will be adjusted to the lesser of (a) the then current conversion price and (b) the greater of (i) $1.44 and (ii) 110.0% of the market price of our common stock on the six-month anniversary of the initial closing date (as applicable, the "Conversion Price"). The Conversion Price is also subject to adjustment for stock splits, stock dividends, recapitalizations, and similar transactions. We have agreed to pay each amortization payment in shares of our common stock, if certain conditions are met; provided, that we may, at our option, elect to pay such amortization payments in cash. The conversion rate applicable to any amortization payment in shares of our common stock will be the lower of (a) the Conversion Price and (b) a price equal to 85.0% of the volume-weighted average price of our shares of common stock for a ten-day period immediately prior to the applicable amortization date. Under the terms of the Warrant, the holder is entitled to exercise the Warrant to purchase up to 1,302,083 shares of our common stock at an initial exercise price of $4.32 per share, during the five-year period beginning on the six-month anniversary of the initial closing date; provided, that 434,027 shares of our common stock issuable upon exercise of the Warrant may not be exercised unless the investor has purchased the Additional Note. On the six-month anniversary of the initial closing date, the exercise price applicable to the Warrant will be adjusted to the lesser of (a) the then current exercise price and (b) 125.0% of the market price of our common stock on the six-month anniversary of the initial closing date (as applicable, the "Exercise Price"). The Exercise Price is also subject to adjustment for stock splits, stock dividends, recapitalizations, and similar transactions. We are generally prohibited from issuing shares of common stock upon exercise of the Warrant if such exercise would cause us to breach our obligations under the rules or regulations of the stock market on which the common stock is traded. In connection with the financing, we entered into a registration rights agreement pursuant to which we agreed to file a registration statement with the Securities and Exchange Commission (with the "SEC") relating to the offer and sale by the investor of the shares of common stock issuable upon conversion of the Notes and the exercise of the Warrant. Pursuant to the agreement, we are required to file the registration statement within six months of the initial closing date and to use its best efforts for the registration statement to be declared effective 90 days thereafter (or 120 days thereafter if the registration statement is subject to review by the SEC).

NOTE P — SUBSEQUENT EVENTS

During November 2011, we entered into a securities purchase agreement (the "Purchase Agreement") with one institutional investor pursuant to which we issued and sold a senior convertible note in the original principal amount of $10.0 million (the "Initial Note") and a warrant (the "Warrant") to purchase up to 1,302,083 shares of our common stock.
