1. Mechanics of Conversion.

a. To convert the shares of the Series J Preferred Stock into shares of Common Stock on any date following the six month anniversary of the Issuance Date (the “ Conversion Date ”), the Holder shall (A) transmit by facsimile (or otherwise deliver) for receipt on or prior to 11:59 p.m., Eastern Time on such date, a copy of a fully executed notice of conversion (the “ Conversion Notice ”) to the Corporation’s designated transfer agent (the “ Transfer Agent ”) with a copy thereto to the Corporation and (b) surrender to a common carrier for delivery to the Transfer Agent at such time the original certificates representing the shares of the Series J Preferred Stock being converted (or a letter attesting to their loss, theft or destruction with respect to such shares in the case of their loss, theft or destruction) (the “ Series J Certificate ”), duly endorsed for transfer.

b. Upon receipt by the Corporation of a copy of the Conversion Notice, the Corporation shall immediately send, via facsimile, a confirmation of receipt of such Conversion Notice to the Holder and the Transfer Agent, which confirmation shall constitute an instruction to the Transfer Agent to process such Conversion Notice in accordance with the terms herein. Upon receipt by the Transfer Agent of the Series J Certificates to be converted pursuant to the Conversion Notice, the Transfer Agent shall, within three business days following the date of receipt, issue and surrender to a common carrier for overnight delivery to the address as specified in the Conversion Notice, a certificate registered in the name of the Holder or its designee for a number of shares of Common Stock to which the Holder shall be entitled. If the number of the shares of the Series J Preferred Stock represented by the Series J Certificate(s) submitted for conversion is greater than the number of Preferred Stock being converted, then the Transfer Agent shall, as soon as practicable and in no event later than three (3) business days after receipt of the Series J Certificate(s), issue and deliver to the Holder a new Series J Certificate representing the number of the shares of the Series J Preferred Stock not converted. The Holder shall be responsible for any legal opinion required by the Transfer Agent related to the issuance of the Conversion Shares.

c. The Holder shall pay any and all taxes that may be payable with respect to the issuance and delivery of the Common Stock upon the conversion of the shares of the Series J Preferred Stock.

2. Payment and Issuance Upon Conversion. In the event of a conversion of any Series J Preferred Stock, the Corporation shall issue to such Holder a number of Conversion Shares equal to (i) the Series J Liquidation Value multiplied by (ii) the number of shares of Series J Preferred Stock held by such Holder and subject to the Holder Conversion Notice, divided by (iii) the Conversion Price with respect to such Series J Preferred Stock, subject to the Conversion Limitations described in Section I.G.3 .

3. Conversion Limitations. Any conversion will be limited by: (i) Holder may not make more than one conversion every ten Trading Days, and (ii) the amount of Conversion Shares at any conversion may not be more than the Conversion Limit.

4. Stock Splits. If the Corporation at any time and from time to time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Conversion Shares will be proportionately increased. If the Corporation at any time and from time to time on or after the first Issuance Date combines (by combination, reverse stock split, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased and the number of Conversion Shares will be proportionately decreased. Any adjustment under this Section I.G.4 shall become effective at the close of business on the date the subdivision or combination becomes effective.

5. Definitions. For purposes of this Section I , the following terms shall have the following meanings:

a. “Conversion Limit” means the total number of shares of Common Stock traded over the ten Trading Days preceding the Conversion Notice multiplied by 5%.

b. “Conversion Price ” means a price per share of Common Stock equal to 100% of the arithmetic average of the volume weighted average price of the Common Stock for the fifteen Trading Days prior to the six month anniversary of the Issuance Date.

c. “ Conversion Shares ” means shares of Common Stock issuable upon conversion of Series J Preferred Stock.

d. “ Trading Day ” means any day on which the Common Stock is traded on the Trading Market; provided that it shall not include any day on which the Common Stock is (i) scheduled to trade for less than 5 hours, or (ii) suspended from trading.

e. “Trading Market ” means the OTC Bulletin Board, the OTCQB, the OTC Pink Sheets, the NASDAQ Capital Market, the NASDAQ Global Market, the NASDAQ Global Select Market, the NYSE Amex, or the New York Stock Exchange, whichever is at the time the principal trading exchange or market for the Common Stock. All Trading Market data shall be measured as provided by the appropriate function of the Bloomberg Professional service of Bloomberg Financial Markets or its successor performing similar functions.

H. Stock Register. The Corporation will keep at its principal office, or at the offices of the transfer agent, a register of the Series J Preferred Stock, which shall be prima facie indicia of ownership of all outstanding shares of Series J Preferred Stock. Upon the surrender of any certificate representing Series J Preferred Stock at such place, the Corporation, at the request of the record Holder of such certificate, will execute and deliver (at the Corporation’s expense) a new certificate or certificates in exchange therefor representing in the aggregate the number of shares represented by the surrendered certificate. Each such new certificate will be registered in such name and will represent such number of shares as is requested by the Holder of the surrendered certificate and will be substantially identical in form to the surrendered certificate.

II. Miscellaneous.

A. Notices. Any and all notices to the Corporation will be addressed to the Corporation’s Chief Executive Officer at the Corporation’s principal place of business on file with the Secretary of State of the State of Delaware. Any and all notices or other communications or deliveries to be provided by the Corporation to any Holder hereunder will be in writing and delivered personally, by electronic mail or facsimile, sent by a nationally recognized overnight courier service addressed to each Holder at the facsimile telephone number or address of such Holder appearing on the books of the Corporation, or if no such facsimile telephone number or address appears, at the principal place of business of the Holder.

B. Lost or Mutilated Preferred Stock Certificate. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered Holder will be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing shares of Series J Preferred Stock, and in the case of any such loss, theft or destruction upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the Holder is a financial institution or other institutional investor its own agreement will be satisfactory) or in the case of any such mutilation upon surrender of such certificate, the Corporation will, at its expense, execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such class represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate.
