Upon any liquidation, dissolution or winding up of the Corporation (each, a “ Liquidation Event ”), whether voluntary or involuntary, each holder of outstanding shares of Series F Preferred Stock shall be entitled to receive and to be paid out of the assets of the Corporation available for distribution to its stockholders (participating pari passu with the holders of Common Stock), the amount which such holder would have been entitled to receive if such Series F Preferred Stock were converted into Common Stock under Section 6 on the date of such liquidation event (the “ Liquidation Preference ”) assuming for purposes of this Section 5 that all outstanding shares of Series F Preferred Stock are convertible on such date. From and after the distribution of such amount, such holder's shares of Series F Preferred Stock shall no longer be deemed to be outstanding, and all rights of such holder relating to such shares shall cease and terminate.

6.                   Conversion .

(a)                Right to Convert . Subject to the terms and conditions of this Section 6, each holder of outstanding shares of Series F Preferred Stock shall have the right to convert, at any time after the first anniversary of the Original Issuance Date, some or all of the outstanding shares of Series F Preferred Stock then held by such holder into that number of fully-paid and non-assessable shares of Common Stock determined by dividing (i) 1.95 multiplied by the number of such shares of Series F Preferred Stock to be converted by (ii) the Conversion Price (as defined below) as of the time of such conversion. Such right of conversion shall be exercised by a holder of outstanding shares of Series F Preferred Stock by delivery of a written notice to the Corporation stating that the holder elects to convert a stated number of shares of Series F Preferred Stock into Common Stock and by surrender of a certificate or certificates for the shares so to be converted (the “ Conversion Certificates ”) to the Corporation at its principal office (or such other office or agency of the Corporation as the Corporation may designate by notice in writing to the holders of outstanding shares of the Series F Preferred Stock) at any time during its usual business hours on the date set forth in such notice.

For purposes of this Section 6(a), the '' Conversion Price ” shall be, as of any specified date with respect to any share of Common Stock, the greater of (A) $1.95 or (B), (i) if the Common Stock is traded on a national securities exchange, the average closing sales price of the Common Stock reported on the exchange for the 10 trading days immediately preceding the Conversion Date (as defined below); or (ii) if the Common Stock is not listed on any national securities exchange but is quoted on an inter-dealer quotation system, the average of the bid and ask prices for the ten trading days immediately preceding the Conversion Date.

(b)                Issuance of Certificate; Time Conversion Effected . Promptly after the receipt of the written notice referred to in Section 6(a) and the surrender of the Conversion Certificates as provided in Section 6(a), the Corporation shall issue and deliver to a holder exercising conversion rights under Section 6(a), at such holder's address as it shall appear on the records of the Corporation, (i) a certificate or certificates representing that number of fully-paid non-assessable shares of Common Stock issuable upon the conversion of such shares of Series F Preferred Stock pursuant to Section 6(a) and (ii) to the extent that such holder exercises his, her or its right to convert some but not all of the outstanding shares of Series F Preferred Stock then held by such holder pursuant to Section 6(a), a certificate or certificates for that number of shares of Series F Preferred Stock represented by the Conversion Certificates for which such holder is not exercising his, her or its conversion rights under Section 6(a) (if any). Such conversion shall be deemed to have been effected as of the date on which the written notice delivered pursuant to Section 6(a) is actually received by the Corporation and the Conversion Certificates shall have been duly surrendered (the " Conversion Date" ). All dividends accrued but unpaid with respect to any shares of Series F Preferred Stock converted under Section 6(a) shall he paid in cash within seven (7) days following the date on which such shares are converted (unless there are no legally available funds with which to make such cash payment, in which event such cash payment shall he made as soon as possible).

(c)                Effect of Subdivision or Combination of Common Stock on Conversions . In case the Corporation shall at any time from and after the Original Issuance Date subdivide by stock split, stock dividend, or otherwise its outstanding shares of Common Stock into a greater number of shares, the number of shares of Common Stock into which the Series F Preferred Stock is convertible shall be proportionately increased; in case the Corporation shall at any time combine (by reverse stock split or otherwise) its outstanding shares of Common Stock into a lesser number of shares, the number of shares of Common Stock into which the Series F Preferred Stock is convertible shall be proportionately decreased.

(d)                Reorganization or Reclassification . If any capital reorganization or reclassification of the capital stock of the Corporation shall be effected in such a way that holders of Common Stock shall be entitled to receive stock, securities, or assets with respect to or in exchange for Common Stock, then, as a condition of such reorganization or reclassification, lawful and adequate provisions shall be made whereby each holder of shares of Series F Preferred Stock shall upon conversion of the Series F Preferred Stock as described in this Certificate of Designation have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of the shares of Common Stock immediately therefor receivable upon the conversion of such share or shares of Series F Preferred Stock, such shares of stock, securities, or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of Common Stock equal to the number of shares of such Common Stock immediately receivable upon such conversion had such reorganization or reclassification not taken place. In any such case, appropriate provisions shall he made with respect to the rights and interests of such holder to the end that the provisions hereof shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities, or assets thereafter deliverable upon the exercise of such conversion rights.

(e)                Mandatory Conversion; Cancellation . Any shares of Series F Preferred Stock outstanding on the fifth anniversary of the Original Issuance Date (the “ Mandatory Conversion Date ”) shall he automatically converted into that number of fully-paid non-assessable shares of Common Stock which the holder thereof would have been entitled to receive had such shares of Series F Preferred Stock been converted into Common Stock pursuant to Section 6(a) on the Mandatory Conversion Date. All certificates evidencing the shares of Series F Preferred Stock held by a holder shall, on the Mandatory Conversion Date or such earlier date on which such certificates are so surrendered for conversion, be deemed to have been retired and canceled and the shares of Series F Preferred Stock represented thereby converted into shares of Common Stock as described above for all purposes. Upon the mandatory conversion of shares of Series F Preferred Stock pursuant to this Section 6(e), all accrued but unpaid dividends thereon shall be paid in cash within seven (7) days following the date on which such shares are converted (unless there are no legally available funds with which to make such cash payment, in which event such cash payment shall be made as soon as possible). The Corporation shall, promptly following the Mandatory Conversion Date, or such earlier date as the certificates representing all of the shares of Series F Preferred Stock held by a holder shall have been duly surrendered by such holder pursuant to this Section 6(e), issue and deliver to such holder, at such holder's address as it shall appear on the records of the Corporation, a certificate or certificates representing that number of fully-paid non-assessable shares of Common Stock issuable upon conversion of such shares pursuant to this Section 6(e).
