Series C 8% Cumulative Convertible Preferred Stock, $.00001 par value.

III. So long as any of the 400 shares of Series B Convertible Preferred Stock designated in the Series B certificate of designations (the “Series B Preferred Stock”) are outstanding, the Series B Preferred Stock shall rank senior to any and all other preferred stock or equity securities of the Corporation, including, without limitation, the Series C Preferred Stock. Notwithstanding anything herein to the contrary, without the prior written consent of the Requisite Holders (as such term is defined in the certificate of designations for the Series B Preferred Stock (the “Series B Designations”)) of the Series B Preferred Stock, or except as expressly permitted in the Series B Designations, no payments shall be made to the holders of the Series C Preferred Stock in respect of such Series C Preferred Stock so long as any shares of Series B Preferred Stock are outstanding.

The number of shares of Series C Preferred Stock shall be 272. Each share of Series C Preferred Stock shall have a stated value equal to $12,000 (as adjusted for any stock dividends, combinations or splits with respect to such shares) (the "Stated Value"), and $.00001 par value. The Corporation may issue fractions of a share of Series C Preferred Stock.
 
2. Dividends.

(a) After all outstanding dividends on the Series B Preferred Stock (with respect to the current fiscal year and all prior fiscal years) shall have been paid to the holders of the Series B Preferred Stock, the holders of outstanding shares of Series C Preferred Stock shall be entitled to receive dividends in cash out of any funds of the Corporation before any dividend or other distribution will be paid or declared and set apart for payment on any shares of any Common Stock, or other class of stock presently authorized or to be authorized other than the Series B Preferred Stock (the Common Stock, and such other stock (other than the Series B Preferred Stock) being hereinafter collectively the "Junior Stock") at the rate of 8% per annum on the Stated Value, until October 1, 2008 and thereafter at the rate of 20% per annum on the Stated Value, payable commencing with the period ending June 30, 2007 and quarterly thereafter.

1


(b) The dividends on the Series C Preferred Stock at the rates provided above shall be cumulative whether or not declared so that, if at any time full cumulative dividends at the rate aforesaid on all shares of the Series C Preferred Stock then outstanding from the date from and after which dividends thereon are cumulative to the end of the quarterly dividend period next preceding such time shall not have been paid or declared and set apart for payment, or if the full dividend on all such outstanding Series C Preferred Stock for the then current dividend period shall not have been paid or declared and set apart for payment, the amount of the deficiency shall be paid or declared and set apart for payment before any sum shall be set apart for or applied by the Corporation or a subsidiary of the Corporation to the purchase, redemption or other acquisition of the Series C Preferred Stock or any shares of any other class of stock ranking on a parity with the Series C Preferred Stock ("Parity Stock") and before any dividend or other distribution shall be paid or declared and set apart for payment on any Junior Stock and before any sum shall be set aside for or applied to the purchase, redemption or other acquisition of Junior Stock.

(c) Dividends on all shares of the Series C Preferred Stock shall begin to accrue and be cumulative from and after the date of issuance thereof. A dividend period shall be deemed to commence on the day following a dividend payment date herein specified and to end on the next succeeding dividend payment date herein specified.

3. Liquidation and Mandatory Redemption Rights.

(a) Upon the dissolution, liquidation or winding-up of the Corporation, whether voluntary or involuntary, and after payment of all amounts that holders of Series B Preferred Stock shall be entitled to receive upon such dissolution, liquidation or winding-up of the Corporation, the Holders of the Series C Preferred Stock shall be entitled to receive before any payment or distribution shall be made on the Junior Stock, out of the assets of the Corporation available for distribution to stockholders, the Stated Value per share of Series C Preferred Stock and all accrued and unpaid dividends to and including the date of payment thereof. Unless otherwise provided in Section 4(b) of the Series B Designations, upon the payment in full of all amounts due to the Holders of the Series B Preferred Stock and the Holders of the Series C Preferred Stock, the Holders of the Common Stock of the Corporation and any other class of Junior Stock shall be entitled to receive all remaining assets of the Corporation legally available for distribution. If the assets of the Corporation available for distribution to the Holders of the Series C Preferred Stock shall be insufficient to permit payment in full of the amounts payable as aforesaid to the Holders of Series C Preferred Stock upon such liquidation, dissolution or winding-up, whether voluntary or involuntary, the holders of Series C Preferred Stock shall share ratably in any distribution of such remaining assets in proportion to the total Series C Liquidation Amount that each of such holders would have received had there been sufficient assets and all such remaining assets of the Corporation shall be distributed to the exclusion of the Holders of shares of Junior Stock.
 
2


(b) The merger or consolidation of the Corporation with or into any other corporation or corporations or the sale or transfer by the Corporation of all or substantially all of its assets shall be deemed to be a liquidation, dissolution or winding-up of the Corporation for the purposes of this paragraph 3.

4. Conversion into Common Stock. Holders of shares of Series C Preferred Stock shall have the following conversion rights and obligations:

(a) Subject to the further provisions of this paragraph 4 each Holder of shares of Series C Preferred Stock shall have the right at any time commencing after the issuance to the Holder of Series C Preferred Stock, to convert any such shares or fractions thereof, accrued and unpaid dividends on such shares, and any other sum owed by the Corporation arising from the Series C Preferred Stock or pursuant to a subscription agreement dated September 30, 2005 or October 3, 2005 entered into by the Corporation and the Holder or Holder’s predecessor in connection with the issuance of Series A 8% Cumulative Convertible Preferred Stock, $.00001 par value per share (“Subscription Agreement”) (collectively “Obligation Amount”) into fully paid and non-assessable shares of Common Stock of the Corporation (as defined in paragraph 4(i) below) determined in accordance with the Conversion Price provided in paragraph 4(b) below (the "Conversion Price"). All issued or accrued but unpaid dividends may be converted at the election of the Holder simultaneously with the conversion of principal amount of Stated Value of Series C Preferred Stock being converted even in circumstances where the Holder would not be entitled to such dividends in cash by operation of Section 2(a) hereof.

(b) The number of shares of Common Stock issuable upon conversion of the Obligation Amount shall equal (i) the sum of (A) the Stated Value per share being converted, (B) at the Holder's election, accrued and unpaid dividends on such share, and (C) at the Holder’s election, provided that the Conversion Price is not less than the conversion price of the Series B Preferred Stock, any other sum owed by the Corporation to the Holder arising from any source including but not limited to the Series C Preferred Stock or Subscription Agreement divided by (ii) the Conversion Price. The Conversion Price as of the date of this Certificate of Designations shall be $1.00, subject to further adjustment as described herein below.

(c) Holder will give notice of its decision to exercise its right to convert the Series C Preferred Stock or part thereof by telecopying an executed and completed Notice of Conversion (a form of which is annexed as Exhibit A to the Certificate of Designation) to the Corporation via confirmed telecopier transmission or otherwise pursuant to Section 13(a) of the Subscription Agreement. The Holder will not be required to surrender the Series C Preferred Stock certificate until the Series C Preferred Stock has been fully converted. Each date on which a Notice of Conversion is telecopied to the Corporation in accordance with the provisions hereof shall be deemed a Conversion Date. The Corporation will itself or cause the Corporation’s transfer agent to transmit the Corporation's Common Stock certificates representing the Common Stock issuable upon conversion of the Series C Preferred Stock to the Holder via express courier for receipt by such Holder within three (3) business days after receipt by the Corporation of the Notice of Conversion (the "Delivery Date"). In the event the Common Stock is electronically transferable, then delivery of the Common Stock must be made by electronic transfer provided request for such electronic transfer has been made by the Holder. A Series C Preferred Stock certificate representing the balance of the Series C Preferred Stock not so converted will be provided by the Corporation to the Holder if requested by Holder, provided the Holder has delivered the original Series C Preferred Stock certificate to the Corporation. To the extent that a Holder elects not to surrender Series C Preferred Stock for reissuance upon partial payment or conversion, the Holder hereby indemnifies the Corporation against any and all loss or damage attributable to a third-party claim in an amount in excess of the actual amount of the Stated Value of the Series C Preferred Stock then owned by the Holder.
 
3


In the case of the exercise of the conversion rights set forth in paragraph 4(a) the conversion privilege shall be deemed to have been exercised and the shares of Common Stock issuable upon such conversion shall be deemed to have been issued upon the date of receipt by the Corporation of the Notice of Conversion. The person or entity entitled to receive Common Stock issuable upon such conversion shall, on the date such conversion privilege is deemed to have been exercised and thereafter, be treated for all purposes as the recordholder of such Common Stock and shall on the same date cease to be treated for any purpose as the record Holder of such shares of Series C Preferred Stock so converted.

Upon the conversion of any shares of Series C Preferred Stock no adjustment or payment shall be made with respect to such converted shares on account of any dividend on the Common Stock, except that the Holder of such converted shares shall be entitled to be paid any dividends declared on shares of Common Stock after conversion thereof.

The Corporation, in connection with any conversion of Series C Preferred Stock, and payment of dividends on Series C Preferred Stock may issue a fraction of a share of its Series C Preferred Stock, or may pay such amount in cash at the stated value of the fractional portion.

The Corporation and Holder may not convert that amount of the Obligation Amount on a Conversion Date in amounts that would result in the Holder having a beneficial ownership of Common Stock which would be in excess of the sum of (i) the number of shares of Common Stock beneficially owned by the Holder and its affiliates on such Conversion Date, and (ii) the number of shares of Common Stock issuable upon the conversion of the Obligation Amount with respect to which the determination of this proviso is being made on such Conversion Date, which would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock of the Corporation. For the purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. Subject to the foregoing, the Holder shall not be limited to successive exercises which would result in the aggregate issuance of more than 4.99%. The Holder may revoke the conversion limitation described in this Paragraph, in whole or in part, upon 61 days prior notice to the Corporation. The Holder may allocate which of the equity of the Corporation deemed beneficially owned by the Holder shall be included in the 4.99% amount described above and which shall be allocated to the excess above 4.99%.
 
4


(d) The Conversion Price determined pursuant to Paragraph 4(b) shall be subject to adjustment from time to time as follows:

(i) In case the Corporation shall at any time (A) declare any dividend or distribution on its Common Stock or other securities of the Corporation other than the Series C Preferred Stock or Series B Preferred Stock, (B) split or subdivide the outstanding Common Stock, (C) combine the outstanding Common Stock into a smaller number of shares, or (D) issue by reclassification of its Common Stock any shares or other securities of the Corporation, then in each such event the Conversion Price shall be adjusted proportionately so that the Holders of Series C Preferred Stock shall be entitled to receive the kind and number of shares or other securities of the Corporation which such Holders would have owned or have been entitled to receive after the happening of any of the events described above had such shares of Series C Preferred Stock been converted immediately prior to the happening of such event (or any record date with respect thereto). Such adjustment shall be made whenever any of the events listed above shall occur. An adjustment made to the Conversion Price pursuant to this paragraph 4(d)(i) shall become effective immediately after the effective date of the event.

(ii) Other than in connection with an Exempted Issuance, if at any time when the Series C Preferred Stock is outstanding, the Company shall offer, issue or agree to issue any Common Stock or securities convertible into or exercisable for shares of Common Stock (or modify any of the foregoing which may be outstanding) to any person or any entity at a price per share or conversion or exercise price per share which will be less than the Conversion Price in respect of the shares issuable upon conversion of the Series C Preferred Stock (the “Preferred Shares”), without the consent of each Holder of Series C Preferred Stock, then the Company shall issue, for each such occasion, additional shares of Common Stock to each Holder of Series C Preferred Stock so that the average per share purchase price of the shares of Common Stock issued to the Holder of Series C Preferred Stock (of only the Preferred Shares still owned by the Holder of the Series C Preferred Stock which Preferred Shares may not be publicly sold by the Holder of Series C Preferred Stock at the time of the dilutive event) is equal to such other lower price per share and the Conversion Price shall automatically be adjusted to such other lower price.

An “Exempted Issuance” shall mean (i) full or partial consideration in connection with a strategic merger, acquisition, consolidation or purchase of substantially all of the securities or assets of corporation or other entity which holders of such securities or debt are not at any time granted registration rights, (ii) the Corporation's issuance of securities in connection with strategic license agreements and other partnering arrangements so long as such issuances are not for the purpose of raising capital which holders of such securities or debt are not at any time granted registration rights, (iii) the Corporation's issuance of Common Stock or the issuances or grants of options to employees, consultants, officers and directors to purchase Common Stock pursuant to stock option plans and employee stock purchase plans duly adopted by a majority of the non-employee members of the Board of Directors of the Corporation or a majority of the members of a committee of non-employee directors established for such purpose hereto, (iv) the Corporation’s issuance of the Series B Preferred Stock, shares of Common Stock upon conversion of the Series B Preferred Stock, or any other securities in exchange therefor, (v) as a result of the exercise of warrants issued to the Holders of Series C Preferred Stock on September 30, 2005 or October 3, 2005 or conversion of Series C Preferred Stock, (vi) the payment of dividends on the Series C Preferred Stock and liquidated damages, and (vii) as has been described in the reports or other written information filed with the Securities and Exchange Commission not later September 27, 2005.
 
5


(e) (i) In case of any merger of the Corporation with or into any other corporation (other than a merger in which the Corporation is the surviving or continuing corporation and which does not result in any reclassification, conversion, or change of the outstanding shares of Common Stock) then unless the right to convert shares of Series C Preferred Stock shall have terminated as part of such merger, lawful provision shall be made so that Holders of Series C Preferred Stock shall thereafter have the right to convert each share of Series C Preferred Stock into the kind and amount of shares of stock and/or other securities or property receivable upon such merger by a Holder of the number of shares of Common Stock into which such shares of Series C Preferred Stock might have been converted immediately prior to such consolidation or merger. Such provision shall also provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in sub-paragraph (d) of this paragraph 4. The foregoing provisions of this paragraph 4(e) shall similarly apply to successive mergers.

(ii) In case of any sale or conveyance to another person or entity of the property of the Corporation as an entirety, or substantially as an entirety, in connection with which shares or other securities or cash or other property shall be issuable, distributable, payable, or deliverable for outstanding shares of Common Stock, then, unless the right to convert such shares shall have terminated, lawful provision shall be made so that the Holders of Series C Preferred Stock shall thereafter have the right to convert each share of the Series C Preferred Stock into the kind and amount of shares of stock or other securities or property that shall be issuable, distributable, payable, or deliverable upon such sale or conveyance with respect to each share of Common Stock immediately prior to such conveyance.

(f) Whenever the number of shares to be issued upon conversion of the Series C Preferred Stock is required to be adjusted as provided in this paragraph 4, the Corporation shall forthwith compute the adjusted number of shares to be so issued and prepare a certificate setting forth such adjusted conversion amount and the facts upon which such adjustment is based, and such certificate shall forthwith be filed with the Transfer Agent for the Series C Preferred Stock and the Common Stock; and the Corporation shall mail to each Holder of record of Series C Preferred Stock notice of such adjusted conversion price.
 
6


(g) In case at any time the Corporation shall propose:

(i) to pay any dividend or distribution payable in shares upon its Common Stock or make any distribution (other than cash dividends) to the Holders of its Common Stock; or

(ii) to offer for subscription to the Holders of its Common Stock any additional shares of any class or any other rights; or

(iii) any capital reorganization or reclassification of its shares or the merger of the Corporation with another corporation (other than a merger in which the Corporation is the surviving or continuing corporation and which does not result in any reclassification, conversion, or change of the outstanding shares of Common Stock); or

(iv) the voluntary dissolution, liquidation or winding-up of the Corporation;

then, and in any one or more of said cases, the Corporation shall cause at least fifteen (15) days prior notice of the date on which (A) the books of the Corporation shall close or a record be taken for such stock dividend, distribution, or subscription rights, or (B) such capital reorganization, reclassification, merger, dissolution, liquidation or winding-up shall take place, as the case may be, to be mailed to the Transfer Agent for the Series C Preferred Stock and for the Common Stock and to the Holders of record of the Series C Preferred Stock.

(h) So long as any shares of Series C Preferred Stock or any Obligation Amount shall remain outstanding and the Holders thereof shall have the right to convert the same in accordance with provisions of this paragraph 4 the Corporation shall at the time of issuance of Series C Preferred Stock reserve from the authorized and unissued shares of its Common Stock 100% of the number of shares of Common Stock that would be necessary to allow the conversion of the entire Obligation Amount.

(i) The term “Common Stock” as used in this Certificate of Designation shall mean the $.00001 par value Common Stock of the Corporation as such stock is constituted at the date of issuance thereof or as it may from time to time be changed, or shares of stock of any class or other securities and/or property into which the shares of Series C Preferred Stock shall at any time become convertible pursuant to the provisions of this paragraph 4.

(j) The Corporation shall pay the amount of any and all issue taxes (but not income taxes) which may be imposed in respect of any issue or delivery of stock upon the conversion of any shares of Series C Preferred Stock, but all transfer taxes and income taxes that may be payable in respect of any change of ownership of Series C Preferred Stock or any rights represented thereby or of stock receivable upon conversion thereof shall be paid by the person or persons surrendering such stock for conversion.

(k) In addition to any other rights available to the Holder, if the Corporation fails to deliver to the Holder such certificate or certificates pursuant to Section 4(c) by the Delivery Date and if within seven (7) business days after the Delivery Date the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Common Stock which the Holder anticipated receiving upon such conversion (a "Buy-In"), then the Corporation shall pay in cash to the Holder (in addition to any remedies available to or elected by the Holder) within five (5) business days after written notice from the Holder, the amount by which (A) the Holder's total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (B) the aggregate Stated Value of the shares of Series C Preferred Stock for which such conversion was not timely honored, together with interest thereon at a rate of 15% per annum, accruing until such amount and any accrued interest thereon is paid in full (which amount shall be paid as liquidated damages and not as a penalty). For example, if the Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of $10,000 of Stated Value of Series C Preferred Stock, the Corporation shall be required to pay the Holder $1,000, plus interest. The Holder shall provide the Corporation written notice indicating the amounts payable to the Holder in respect of the Buy-In.
 
7


(m) The Corporation understands that a delay in the delivery of Common Stock upon conversion of Preferred Stock in the form required pursuant to this Certificate and the Subscription Agreement after the Delivery Date could result in economic loss to the Holder. As compensation to the Holder for such loss, the Corporation agrees to pay (as liquidated damages and not as a penalty) to the Holder for such late issuance of Common Stock upon Conversion of the Series C Preferred Stock in the amount of $100 per business day after the Delivery Date for each $10,000 of Obligation Amount being converted of the corresponding Common stock which is not timely delivered. The Corporation shall pay any payments incurred under this section in immediately available funds upon demand. Furthermore, in addition to any other remedies which may be available to the Holder, in the event that the Corporation fails for any reason to effect delivery of the Common Stock by the Delivery Date, the Holder will be entitled to revoke all or part of the relevant Notice of Conversion or rescind all by delivery of a notice to such effect to the Corporation whereupon the Corporation and the Holder shall each be restored to their respective positions immediately prior to the delivery of such notice, except that the liquidated damages described above shall be payable through the date notice of revocation is given to the Corporation.

(n) In the event a Holder shall elect to convert any part of the Obligation Amount, the Corporation may not refuse conversion based on any claim that Holder or any one associated or affiliated with Holder has been engaged in any violation of law, or for any other reason, unless, an injunction from a court, on notice, restraining and or enjoining conversion of all or part of such Obligation Amount shall have been sought and obtained by the Corporation and the Corporation has posted a surety bond for the benefit of such Holder in the amount of 120% of the amount of the Obligation Amount which are sought to be subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent Holder obtains judgment.

(o)  Commencing after the Actual Effective Date (as defined in the Subscription Agreement), provided an Event of Default has not occurred, and provided further that no Series B Preferred Stock is outstanding, whether or not such Event of Default has been cured, the Corporation will have the option of prepaying the Obligation Amount ("Optional Redemption"), in whole or in part, by paying to the Holder a sum of money equal to one hundred twenty percent (120%) of the Obligation Amount to be redeemed (the "Redemption Amount"). The Corporation’s election to exercise its right to prepay must be by notice in writing (“Notice of Redemption”) and made proportionately to all Holders of Series C Preferred Stock. The Notice of Redemption shall specify the date for such Optional Redemption (the "Redemption Payment Date"), which date shall be not less than thirty (30) business days after service of the Notice of Redemption (the "Redemption Period"). A Notice of Redemption shall not be effective with respect to any portion of the Obligation Amount for which the Holder has a pending election to convert pursuant to Section 4 hereof, or for conversions initiated or made by the Holder during the Redemption Period. On the Redemption Payment Date, the Redemption Amount less any portion of the Redemption Amount against which the Holder has exercised its rights pursuant to Section 4, shall be paid in good funds to the Holder. In the event the Corporation fails to pay the Redemption Amount on the Redemption Payment Date as set forth herein, then (i) such Notice of Redemption will be null and void, (ii) the Corporation will have no further right to deliver a Notice of Redemption, and (iii) the Corporation’s failure may be deemed by the Holder to be a non-curable Event of Default.
 
8

6. Restrictions and Limitations.
