In addition to certain other restrictions contained herein, so long as any shares of Series C Stock are outstanding, the Company shall not (i) declare, pay or set apart for payment any dividend on, or make any distribution in respect of, the Junior Securities or any warrants, rights, calls or options exercisable for or -4- convertible into any of the Junior Securities, either directly or indirectly, whether in cash, obligations or shares of the Company or other property (other than distributions or dividends of a particular class or series of Junior Securities, or warrants, rights or options exercisable for such Junior Securities, to holders of such Junior Securities), or (ii) make any payment on account of, or set apart for payment money for a sinking or other similar fund for, the purchase, redemption, retirement or other acquisition for value of any of, or redeem, purchase, retire or otherwise acquire for value any of, the Junior Securities (other than as a result of a reclassification of Junior Securities into other Junior Securities or the exchange or conversion of one class or series of Junior Securities for or into another class or series of Junior Securities) or any warrants, rights, calls or options exercisable for or convertible into any of the Junior Securities, or (iii) permit any corporation or other entity directly or indirectly controlled by the Company to purchase, redeem, retire or otherwise acquire for value any of the Junior Securities or any warrants, rights, calls or options exercisable for or convertible into any of the Junior Securities, unless, and in each such case, prior to or concurrently with such declaration, payment, setting apart for payment, purchase, redemption, retirement or other acquisition for value or distribution in respect of Junior Securities, all accumulated and unpaid dividends (including accumulated dividends, if any, not paid by reason of the terms and conditions of Section 4.e hereof), if any, on shares of Series C Stock shall have been paid through the most recent Dividend Payment Date or, if such declaration, payment, setting apart for payment, purchase, redemption, retirement, other acquisition for value or distribution occurs on a Dividend Payment Date, through such Dividend Payment Date; PROVIDED, HOWEVER, that the restrictions provided in this subparagraph d. shall not apply to the repurchase of shares of Common Stock held by any employee or consultant of the Company or any of its subsidiaries (or their permitted transferees) in connection with the termination of such employee's or consultant's services to the Company or any of its subsidiaries. E. RESTRICTIONS ON PAYMENT OF DIVIDENDS. Notwithstanding anything contained herein to the contrary, no cash dividends on shares of Series C Stock shall be declared -5- by the Board or paid or set apart for payment by the Company: (i) unless, prior to or concurrently with such declaration, payment or setting apart, all accrued and unpaid dividends, if any, on shares of Senior Securities shall have been paid or declared and set apart for payment through the dividend payment period with respect to such Senior Securities which immediately precedes or coincides with the date of declaration, payment or setting apart for payment by the Company of such cash dividends; or (ii) at such time as such declaration, payment or setting apart is prohibited by the DGCL; or (iii) at such time as the terms and provisions of any contract or other agreement of the Company or any of its subsidiaries entered into or assumed providing financing or working capital to the Company or any of its subsidiaries (whether entered into prior to, at or after the issuance of the Series C Stock), specifically prohibits such declaration, payment or setting apart for payment or provides that such declaration, payment or setting apart for payment would constitute a breach thereof or a default thereunder. 5. LIQUIDATION PREFERENCE. A. GENERAL. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, the holders of Series C Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets or surplus funds of the Company in respect of any Junior Securities, but after all required distributions of assets and surplus funds in respect of any Senior Securities, an amount equal to the Face Amount per share plus accumulated and unpaid dividends to the date fixed for liquidation, dissolution or winding up. Upon any liquidation, dissolution or winding up of the Company, after payment shall have been made in full on the Series C Stock as provided in the preceding sentence, but not prior thereto, the holders of Junior Securities shall, subject to the respective terms and provisions applying thereto, if any, be entitled to receive any and all assets and surplus funds remaining to be paid or distributed, and the Series C Stock shall not be entitled to share therein. B. DISTRIBUTIONS PRO RATA. If upon any liquidation, dissolution or winding up of the Company the amounts payable on or with respect to the Series C Stock are -6- not paid in full, the holders of shares of Series C Stock together with all classes or series of stock ranking on a parity with the Series C Stock as to distribution of assets and surplus funds shall share ratably in any distribution of assets according to the respective amounts which would be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to the Series C Stock and any other class or series of stock that so ranks on a parity with the Series C Stock were paid in full. C. MERGER OR CONSOLIDATION. Neither the merger nor consolidation of the Company with another corporation nor the sale or lease of all or substantially all of the assets of the Company shall be deemed to be a liquidation, dissolution or winding up of the Company. D. NOTICE REQUIRED. Written notice of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, stating the payment date and the place where the distributable amount shall be payable, shall be given by mail, postage prepaid, not less than thirty (30) days prior to the payment date stated therein, to the holders of record of the Series C Stock at their respective addresses as the same shall then appear on the books of the Company. 6. CONVERSION. A. EXERCISE OF CONVERSION RIGHT. Each holder of Series C Stock shall have the right, at his or her option, at any time and from time to time after issuance of the Series C Stock, to convert, subject to the terms and provisions of this Section 6, all or any portion of its Series C Stock then outstanding into fully paid and non-assessable shares of Common Stock at a conversion rate of twenty (20) shares of Common Stock for each one (1) share of Series C Stock (the "CONVERSION RATE"). At the time of any such conversion, any accumulated and unpaid dividends on the Series C Stock to be so converted shall likewise be converted, at the Conversion Rate, into fully paid and non- assessable shares of Common Stock. Any such conversion shall be deemed to have been made at the close of business on the date that the certificate or certificates for shares of Series C Stock shall have been surrendered for conversion and written notice shall have been -7- received as provided in Section 6.b (the "CONVERSION DATE"), so that the person or persons entitled to receive the shares of Common Stock upon conversion of such shares of Series C Stock shall be treated for all purposes as having become the record holder or holders of such shares of Common Stock at such time. B. NOTICE TO COMPANY. In order to convert all or any portion of its outstanding Series C Stock into shares of Common Stock, the holder of such Series C Stock shall deliver the shares to be converted to the Company at its principal office, together with written notice that it elects to convert those shares of Series C Stock into shares of Common Stock in accordance with the provisions of this Section 6. Such notice shall specify the number of shares of Series C Stock to be converted and the name or names in which the holder wishes the certificates for shares of Common Stock to be registered, together with the address or addresses of the person or persons so named, and, if so required by the Company, be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, duly executed by the registered holder of the shares of Series C Stock to be converted or by his or her attorney duly authorized in writing. C. DELIVERY OF CERTIFICATE. As promptly as practicable after the surrender as hereinabove provided of shares of Series C Stock for conversion into shares of Common Stock, the Company shall deliver or cause to be delivered to the holder, or the holder's designees, certificates representing the number of fully paid and non-assessable shares of Common Stock into which the shares of Series C Stock (and any accumulated and unpaid dividends thereon) are entitled to be converted, together with a cash adjustment in respect of any fraction of a share of Common Stock to which the holder would otherwise be entitled, and, if less than the entire number of shares of Series C Stock represented by the certificate or certificates surrendered is to be converted, a new certificate for the number of shares of Series C Stock not so converted. So long as any shares of Series C Stock remain outstanding, the Company shall not close its Common Stock transfer books. The issuance of certificates for shares of Common Stock upon the conversion of shares of Series C Stock shall be made without charge to the holder for any tax in -8- respect of the issuance of such certificates (other than any transfer tax if the shares of Common Stock are to be registered in a name different from that of the registered holder of Series C Stock). D. FRACTIONAL SHARES. No fractional shares of Common Stock or scrip representing fractional shares of Common Stock shall be issued upon any conversion of any shares of Series C Stock, but, in lieu thereof, there shall be paid an amount in cash equal to the same fraction of the Market Price of a whole share of Common Stock as of the Conversion Date. E. ADJUSTMENT TO CONVERSION RATE. The Conversion Rate and other terms of conversion shall be subject to adjustment from time to time as follows: (1) If, at any time or times after issuance of shares of Series C Stock, the Company shall (x) declare and pay to the holders of Common Stock a dividend or other distribution payable in shares of Common Stock or (y) subdivide the outstanding shares of Common Stock into a greater number of shares of Common Stock or combine the outstanding shares of Common Stock into a lesser number of shares or issue by reclassification of its shares of Common Stock any shares of the Company or other property, then in each such case the Conversion Rate and other terms of conversion in effect immediately prior thereto shall be adjusted so that the holders of Series C Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock or other securities or property which such holder would have owned or been entitled to receive after the declaration and payment of the dividend or other distribution described in clause (x) or after the happening of the event described in clause (y), if such shares of Series C Stock had been converted immediately prior to the record date for the determination of stockholders entitled to receive the dividend or other distribution described in clause (x) or the happening of the event described in clause (y) on the day upon which such event becomes effective. (2) If, at any time or times after the issuance of shares of Series C Stock, the Company shall effect a reorganization, shall merge with or into or consolidate into another corporation, or shall sell, transfer or otherwise -9- dispose of all or substantially all of its property, assets or business and, pursuant to the terms of such reorganization, merger, consolidation or disposition of assets, shares of stock or other securities, property or assets of the Company (or the successor, transferee or affiliate of the Company) or cash are to be received by or distributed to the holders of Common Stock, then the holder of shares of Series C Stock shall have the right thereafter to receive, upon conversion of each share of Series C Stock, the number of shares of stock or other securities, property or assets of the Company (or the successor, transferee or affiliate of the Company), or cash receivable upon or as a result of such reorganization, merger, consolidation or disposition of assets by a holder of the number of shares of Common Stock into which a share of Series C Stock was convertible immediately prior to such event. The provisions of this subparagraph (2) shall similarly apply to successive reorganizations, mergers, consolidations or dispositions of assets. (3) Anything herein to the contrary notwithstanding, no adjustments pursuant to this Section 6.e shall be made by reason of or in connection with the issuance of shares of Common Stock upon (x) conversion of any shares of Series C Stock, (y) conversion of any convertible securities of the Company outstanding as of the date on which this Certificate is filed with the Secretary of State of the State of Delaware or (z) exercise of any warrant, option or other right entitling the holder thereof to subscribe for or purchase shares of Common Stock.

The Company shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of shares of Series C Stock, the full number of whole shares of Common Stock then deliverable upon the conversion of all shares of Series C Stock then outstanding. The Company shall take at all times such corporate action as shall be necessary in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the conversion of shares of Series C Stock in accordance with the provisions of this Section 6. -10- G. RETIREMENT OF SHARES. Any shares of Series C Stock converted pursuant to the provisions of this Section 6 shall be retired and given the status of authorized and unissued Preferred Stock, undesignated as to series, subject to reissuance by the Company as shares of Preferred Stock of one or more series, as may be determined from time to time by the Board. 7.

The date of redemption shall be the date fixed therefor in the notice of redemption. B. PRO RATA REDEMPTION. If less than all outstanding Series C Stock is to be redeemed, the redemption may be made either pro rata or by lot or in some other -11- equitable manner as may be prescribed by resolution of the Board. C. NOTICE OF REDEMPTION. Any notice of redemption mailed to a holder of Series C Stock at his or her address as the same shall appear on the books of the Company shall be conclusively presumed to have been given whether or not the holder receives the notice. Each such notice shall state: the date of redemption; the number of shares of Series C Stock to be redeemed, and, if less than all shares of Series C Stock held by such holder are to be redeemed, the number of such shares to be redeemed from him or her and the fact that a new certificate or certificates representing any unredeemed shares shall be issued without cost to such holder; the redemption price applicable to the shares to be redeemed; the place or places where such shares are to be surrendered; and that shares to be redeemed may be converted at any time prior to the close of business on the business day immediately preceding the redemption date pursuant to Section 6 hereof, giving the then applicable Conversion Rate.
