ARTICLE 4

The Corporation shall be authorized to issue 31,428,570 shares of all classes, consisting of (i) 20,369,550 shares of Common Stock, $0.001 par value (the “Common Stock”), and (ii) 11,059,020 shares of Preferred Stock, $0.001 par value (the “Preferred Stock”). Effective upon filing of this Restated Certificate of Incorporation, each ten and one-half (10.5) outstanding shares of Common Stock shall be combined into one (1) share of Common Stock, each ten and one-half (10.5) outstanding shares of Series A Preferred Stock shall be combined into one (1) share of Series A Preferred Stock and each ten and one-half (10.5) outstanding shares of Series C Preferred Stock shall be combined into one (1) share of Series C Preferred Stock, in each case with the rights, preferences, privileges and restrictions set forth herein. Such combination shall be effected on a stockholder-by-stockholder basis, and the holder of any fractional shares resulting from such combination shall, in lieu thereof, be entitled to receive a cash payment in an amount equal to the fraction to which the stockholder would otherwise be entitled multiplied by the fair value of a share as determined in good faith by the Board of Directors.

The following is a statement of the designation and the powers, privileges and rights and the qualifications, limitations or restrictions thereof in respect of each class of capital stock of the Corporation.

4.1 Common Stock.

Each share of Common Stock shall be identical in all respects and for all purposes and entitled to one vote in all proceedings in which action may or is required to be taken by stockholders of the Corporation; participate equally in all dividends payable with respect to the Common Stock, as, if and when declared by the Board of Directors of the Corporation subject to any dividend preference in favor of Series C Preferred Shares (as defined below) and Series A Preferred Shares (as defined below); and share ratably in all distributions of assets of the Corporation in the event of any voluntary or involuntary liquidation, or winding up of the affairs of the Corporation, subject to any liquidation rights and preferences in favor of Series C Preferred Shares and Series A Preferred Shares.

In connection with any stock split, reverse split, combination, consolidation, reclassification or similar event, the Corporation shall not issue any fractional shares of the Common Stock. In lieu of such fractional shares of Common Stock which would otherwise be issuable, the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount equal to the product of (i) the Fair Market Value (as defined below) of one share of Common Stock and (ii) such fractional interest, and, upon payment of such cash adjustment, the holders of fractional interests shall not be entitled to any rights as stockholders of the Corporation in respect of such fractional interests.

4.2 Preferred Stock.

The Preferred Stock shall consist of a series designated as “Series A Convertible Preferred Stock”, a series designated as “Series B Preferred Stock” and a series designated as “Series C Convertible Preferred Stock”. The shares of Series A Convertible Preferred Stock are referred to herein as the “Series A Preferred Shares”, the share of Series B Preferred Stock is referred to herein as the “Series B Preferred Share” and the shares of Series C Convertible Preferred Stock are referred to herein as the “Series C Preferred Shares”.

The Series A Convertible Preferred Stock shall consist of 8,201,877 Series A Preferred Shares. The Series B Preferred Stock shall consist of one Series B Preferred Share. The Series C Convertible Preferred Stock shall consist of 2,857,142 Series C Preferred Shares.

4.3 Series A Convertible Preferred Stock

4.3.1 Dividends.

The holders of outstanding Series A Preferred Shares shall be entitled to receive dividends, if, when and as declared by the Board of Directors of the Corporation (the “Board”), out of any assets at the time legally available therefore, in an amount per share equal to $0.33317 per annum (representing 8% of the Series A Purchase Price (as defined below)) (subject to equitable adjustments as a result of any stock dividend, stock split, combination, reverse split, reclassification or similar events with respect to the Series A Preferred Shares after the effective date of this Second Amended and Restated Certificate of Incorporation (the “Restated Certificate”)) after any dividend or other distribution is declared or paid on Series C Preferred Shares but before any dividend or other distribution is declared or

paid on shares of Common Stock or any other class of capital stock of the Corporation ranking junior to the Series A Preferred Shares. Dividends may be payable annually or otherwise as the Board may from time to time determine. The right to such dividends on Series A Preferred Shares shall not be cumulative and no right shall accrue to the holders of Series A Preferred Shares by reason of the fact the dividends on said shares are not declared in any prior year, nor shall any undeclared or unpaid dividend bear or accrue interest. Declared but unpaid dividends on any Series A Preferred Share shall, upon conversion of such shares, be paid to the extent assets of the Corporation are legally available therefor either in cash or in shares of Common Stock, as determined by the Board. The price of one (1) share of Common Stock shall be determined in good faith by the Board at the date of payment of such dividends. Any amount for which assets of the Corporation are not legally available shall be paid promptly as assets become legally available therefor.

4.3.2 Liquidation.

4.3.2.1 Upon any Liquidation (as defined below), after payment or provision for payment of the debts and other liabilities of the Corporation and the Series C Preference Amount (as defined below in Section 4.5.2.1), the holders of Series A Preferred Shares shall be entitled to receive, out of the remaining assets of the Corporation available for distribution to its stockholders, with respect to each Series A Preferred Share an amount (the “Series A Preference Amount”) equal to the sum of (i) $4.165035 per share (the “Series A Purchase Price”) (subject to equitable adjustment as a result of any stock dividend, stock split, combination, reverse split, reclassification or similar event with respect to the Series A Preferred Shares after the effective date of this Restated Certificate), and (ii) all declared but unpaid dividends payable with respect to each such share under Section 4.3.1 above, before any distribution shall be made to the holders of shares of the Common Stock, or any other class of capital stock of the Corporation ranking junior to the Series A Preferred Shares upon a Liquidation. Upon any Liquidation and after the payment of the Series C Preference Amount, if the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay to the holders of Series A Preferred Shares the full aggregate Series A Preference Amounts to which they are entitled, the holders of Series A Preferred Shares shall share pro rata in any distribution of assets in accordance with the Series A Preference Amounts they would otherwise have been entitled to receive.

4.3.2.2 Upon any Liquidation, after payment or provision for payment in full of the Series C Preference Amounts and the Series A Preference Amounts, the holders of shares of Common Stock, the holders of the Series A Preferred Shares and the holders of the Series C Preferred Shares shall be entitled to share in the distribution of the remaining

assets of the Corporation pro rata based on the number of shares of Common Stock held by each such holder, treating for this purpose all securities held by such holder as if such securities had been converted to shares of Common Stock pursuant to the terms of this Restated Certificate immediately prior to such Liquidation. For purposes of clarity, the participation rights of the stockholders described in this Section 4.3.2.2 do not grant to the stockholders any additional participation rights to those participation rights described in Section 4.5.2.2.

4.3.2.3 “Liquidation” means (i) any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, other than any dissolution, liquidation or winding up in connection with any reincorporation of the Corporation in another jurisdiction, (ii) any transaction or series of related transactions, including, without limitation, any merger or consolidation of the Corporation with or into another corporation or person or entity (other than with or into a wholly-owned subsidiary), or the sale of capital stock of the Corporation by the Corporation or the holders thereof, in any case under circumstances in which the holders of the outstanding capital stock of the Corporation immediately prior to such transaction or series of related transactions shall own less than a majority in voting power of the outstanding capital stock of the Corporation or the surviving or resulting corporation or other entity, as the case may be, immediately following such transaction or (iii) the sale or transfer of all or substantially all of the assets of the Corporation or the exclusive license of all or substantially all of the material intellectual property of the Corporation (sub-sections (ii) and (iii) above being hereinafter collectively referred to as a “Corporate Transaction”).

4.3.2.4 If any assets of the Corporation distributed to stockholders in connection with any Liquidation are other than cash, then the value of such assets shall be the Fair Market Value (as defined below) thereof, except that any publicly-traded securities to be distributed to stockholders in a Liquidation shall be valued as follows:

(1) If the securities are then traded on a national securities exchange or the Nasdaq Stock Market (or a similar national quotation system), then the value of such securities shall be deemed to be the average of the closing prices of the securities on such exchange or system over the ten (10) trading day period ending five (5) trading days prior to the distribution;

(2) If the securities are actively traded over-the-counter, then the value of such securities shall be deemed to be the average of the closing bid prices of the securities over the ten (10) trading day period ending five (5) trading days prior to the distribution;

(3) If the securities are not so traded, then the value of such securities shall be the Fair Market Value thereof.

4.3.2.5 In the event of a merger or other acquisition of the Corporation by another entity, the distribution date shall be deemed to be the date such transaction closes.

4.3.2.6 “Trading day” shall mean any day which the exchange or system on which the securities to be distributed are traded is open and “closing prices” or “closing bid prices” shall be deemed to be: (i) for securities traded primarily on the New York Stock Exchange, the American Stock Exchange or Nasdaq, the last reported trade price or sale price, as the case may be, at 4:00 p.m., New York time, on that day and (ii) for securities listed or traded on other exchanges, markets and systems, the market price as of the end of the regular hours trading period that is generally accepted as such for such exchange, market or system. If, after the date hereof, the benchmark times generally accepted in the securities industry for determining the market price of a stock as of the close of a given trading day shall change from those set forth above, the fair market value shall be determined as of such other generally accepted benchmark times.

4.3.2.7 “Fair Market Value” shall mean the fair market value as determined by the Board in good faith and approved by the holders of two-thirds of the then outstanding Series A Preferred Shares and Series C Preferred Shares voting together as one class. If not approved as provided above, the Fair Market Value shall be determined by a third party appointed by the Corporation and approved by the holders of two-thirds of the then outstanding Series A Preferred Shares and Series C Preferred Shares, voting together as one class, who shall be an expert appraiser working for a nationally recognized appraisal firm having experience in the Corporation’s industry. The decision of such third party shall be binding and the costs of such third party shall be borne by the Corporation.

4.3.2.8. “Pre-Split Series A Purchase Price” shall mean $0.39667 per share.

4.3.3 Redemption.

The Series A Preferred Shares shall not be redeemable.

4.3.4 Voting Rights.

In addition to the rights provided by law and the rights provided in Article 5 and Article 6, except as provided herein, the holders of the Series A Preferred Shares shall be entitled to vote on all matters as to which holders of shares of Common Stock shall be entitled to vote, in the same manner and with the same effect as such holders of shares of Common Stock, voting together with the holders of shares of Common Stock and the holder of the Series B Preferred Share and the

holders of Series C Preferred Shares as one class. Each Series A Preferred Share shall entitle the holder thereof to such number of votes as shall equal the number of whole shares of Common Stock into which such Series A Preferred Share is then convertible pursuant to Section 4.3.5.

4.3.5 Optional Conversion.

4.3.5.1 Upon the terms set forth in this Section 4.3.5, each holder of Series A Preferred Shares shall have the right, at such holder’s option, at any time and from time to time, to convert any of such shares into the number of fully paid and non-assessable shares of Common Stock equal to the quotient obtained by dividing (i) the product of the Series A Purchase Price and the number of Series A Preferred Shares being converted, by (ii) the Series A Conversion Price (as defined below), as last adjusted and then in effect, by surrender of the certificates representing the Series A Preferred Shares to be converted. The initial conversion price per share at which shares of Common Stock shall be issuable upon conversion of Series A Preferred Shares shall be $4.165035 (the “Series A Conversion Price”). The Series A Conversion Price shall be subject to adjustment from time to time in accordance with Section 4.3.5.4 below.

4.3.5.2 Any holder of Series A Preferred Shares may exercise the conversion right pursuant to Section 4.3.5.1 above, by delivering to the Corporation the certificate or certificates for the shares to be converted, duly endorsed or assigned in blank to the Corporation (if required by it), accompanied by written notice stating that the holder elects to convert such shares and stating the name or names (with address) in which the certificate or certificates for the shares of Common Stock are to be issued. Conversion shall be deemed to have been effected at the close of business on the date when such delivery is made (the “Series A Conversion Date”). As promptly as practicable thereafter, the Corporation shall issue and deliver to the place designated by such holder, a certificate or certificates for the number of full shares of Common Stock to which such holder is entitled, and a cash amount in respect of any fractional interest in a share of Common Stock as provided in Section 4.3.5.3 below. The person in whose name the certificate or certificates for shares of Common Stock are to be issued shall be deemed to have become a stockholder of record on the applicable Series A Conversion Date unless the transfer books of the Corporation are closed on that date, in which event such person shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open, but the Series A Conversion Price shall be that in effect on the Series A Conversion Date. Upon conversion of only a portion of the number of shares covered by a certificate representing Series A Preferred Shares surrendered for conversion, the Corporation shall issue and deliver to

the holder of the certificate so surrendered for conversion, at the expense of the Corporation, a new certificate covering the number of such Series A Preferred Shares representing the unconverted portion of the certificate so surrendered.

4.3.5.3 Upon conversion, the Corporation shall not issue fractional shares of its Common Stock. The number of full shares of Common Stock issuable upon conversion of any Series A Preferred Shares shall be computed on the basis of the aggregate number of Series A Preferred Shares to be converted. If fractional shares of Common Stock are issuable, the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount equal to the product of (i) the price of one share of Common Stock as determined in good faith by the Board and (ii) such fractional interest, and, upon payment of such cash adjustment, the holders of fractional interests shall not be entitled to any rights as stockholders of the Corporation in respect of such fractional interests.

4.3.5.4 The Series A Conversion Price shall be subject to adjustment from time to time as follows:

(1) If the Corporation shall, at any time or from time to time after the date of original issuance of the first Series A Preferred Share (the “Series A Original Issuance Date”), issue any shares of Common Stock or other Equity Securities (as defined below) other than Series A Excluded Stock (as defined below) allowing for the acquisition of shares of Common Stock without consideration or for a consideration per share less than the Series A Conversion Price for such Series A Preferred Shares in effect immediately prior to the issuance of such shares of Common Stock or Equity Securities (which in the case of Equity Securities other than shares of Common Stock shall include the consideration received by the Corporation upon issuance thereof and any consideration received by the Corporation in any intermediate exchange or exercise thereof for Equity Securities other than shares of Common Stock), then the Series A Conversion Price in effect immediately prior to each such issuance shall forthwith be lowered to a price equal to the quotient obtained by dividing:

(A) an amount equal to the sum of (x) the total number of shares of Common Stock outstanding (including any shares of Common Stock deemed to have been issued pursuant to Section 4.3.5.4(2)(C) below immediately prior to such issuance, multiplied by the Series A Conversion Price in effect immediately prior to such issuance, and (y) the aggregate consideration received by the Corporation upon such issuance; by

(B) the total number of shares of Common Stock outstanding (including any shares of Common Stock deemed to have been issued pursuant to Section 4.3.5.4(2)(C) immediately after the issuance of such shares of Common Stock.

(2) For the purposes of any adjustment of the Series A Conversion Price pursuant to Section 4.3.5.4(1) above, the following provisions shall be applicable:

(A) In the case of the issuance of shares of Common Stock for cash in a private placement, the consideration shall be deemed to be the amount of cash paid therefor without deducting therefrom any discounts, commissions or placement fees payable by the Corporation to any underwriter or placement agent in connection with the issuance and sale thereof.

(B) In the case of the issuance of shares of Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the Fair Market Value thereof.

(C) In the case of the issuance of options or warrants to purchase or rights to subscribe for shares of Common Stock, securities by their terms convertible into or exchangeable for shares of Common Stock, or options or warrants to purchase or rights to subscribe for such convertible or exchangeable securities:

1. the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options or warrants to purchase or rights to subscribe for shares of Common Stock shall be deemed to have been issued at the time such options or warrants or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections 4.3.5.4(2)(A) and 4.3.5.4(2)(B) above), if any, received by the Corporation upon the issuance of such options, warrants or rights plus the minimum purchase price provided in such options, warrants or rights for the shares of Common Stock covered thereby;

2. the aggregate maximum number of shares of Common Stock deliverable upon conversion or exercise of or in exchange for any such convertible,

exercisable or exchangeable securities or upon the exercise of options or warrants to purchase or rights to subscribe for such convertible, exercisable or exchangeable securities and subsequent conversion, exercise or exchange thereof shall be deemed to have been issued at the time such securities, options, warrants or rights were issued and for a consideration equal to the consideration received by the Corporation for any such securities and related options, warrants or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options, warrants or rights (the consideration in each case to be determined in the manner provided in Sections 4.3.5.4(2)(A) and 4.3.5.4(2)(B) above);

3. on any change in the number of shares or exercise price of shares of Common Stock deliverable upon exercise of any such options, warrants or rights or conversion or exercise of or exchange for such securities, other than a change resulting from the anti-dilution provisions thereof, the Series A Conversion Price shall forthwith be readjusted to such Series A Conversion Price as would have obtained had the adjustment made upon the issuance of such options, warrants, rights or securities not converted, exercised or exchanged prior to such change or options, warrants or rights related to such securities not converted, exercised or exchanged prior to such change been made upon the basis of such change; and

4. on the expiration of any such options, warrants or rights, the termination of any such rights to convert, exercise or exchange or the expiration of any options, warrants or rights related to such convertible, exercisable or exchangeable securities, the Series A Conversion Price shall forthwith be readjusted to such Series A Conversion Price as would have obtained had the adjustment made upon the issuance of such options, warrants, rights, securities or options, warrants or rights related to such securities been made upon the basis of the issuance of only the number of shares of Common

Stock actually issued upon the exercise of such options, warrants or rights, upon the conversion or exchange of such securities, or upon the exercise of the options, warrants or rights related to such securities and subsequent conversion, exercise or exchange thereof.

In the case of any action which would require the fixing of a record date, such notice shall be given at least 20 days prior to the date so fixed, and in case of all other action, such notice shall be given at least 30 days prior to the taking of such proposed action.

The holders of outstanding Series C Preferred Shares shall be entitled to receive dividends, if, when and as declared by the Board, out of any assets at the time legally available therefor, in an amount per share equal to $0.42 per annum (representing 8% of the Series C Purchase Price (as defined below)) (subject to equitable adjustments as a result of any stock dividend, stock split, combination, reverse split, reclassification or similar events with respect to the Series C Preferred Shares after the effective date of this Restated Certificate before any dividend or other distribution is declared or paid on Series A Preferred Shares, on shares of Common Stock, on any other class of capital stock of the Corporation ranking junior to the Series C Preferred Shares. Dividends may be payable annually or otherwise as the Board may from time to time determine. The right to such dividends on Series C Preferred Shares shall not be cumulative and no right shall accrue to the holders of Series C Preferred Shares by reason of the fact the dividends on said shares are not declared in any prior year, nor shall any undeclared or unpaid dividend bear or accrue interest. Declared but unpaid dividends on any Series C Preferred Share shall, upon conversion of such shares, be paid to the extent assets of the Corporation are legally available therefor either in cash or in shares of Common Stock, as determined by the Board. The price of one (1) share of Common Stock shall be determined in good faith by the Board at the date of payment of such dividends. Any amount for which assets of the Corporation are not legally available shall be paid promptly as assets become legally available therefor.

4.5.2 Liquidation.

4.5.2.1 Upon any Liquidation (as defined in Section 4.3.2.3), after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of Series C Preferred Shares shall be entitled to receive, out of the remaining assets of the Corporation available for distribution to its stockholders, with respect to each Series C Preferred Share an amount (the “Series C Preference Amount”) equal to the sum of (i) $5.25 per share (the “Series C Purchase Price”) (subject to equitable adjustment as a result of any stock dividend, stock split, combination, reverse split, reclassification or similar event with respect to the Series C Preferred Shares after the effective date of this Restated Certificate), and (ii) all declared but unpaid dividends payable with respect to each such share under Section 4.5.1 above, before any distribution shall be made to the holders of Series A Preferred Shares, the holders of shares of the Common Stock, or the holders of any other class of capital stock of the Corporation ranking junior to the Series C Preferred Shares upon a Liquidation. If upon such Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay to the

holders of Series C Preferred Shares the full aggregate Series C Preference Amounts to which they are entitled, the holders of Series C Preferred Shares shall share pro rata in any distribution of assets in accordance with the Series C Preference Amounts they would otherwise have been entitled to receive.

4.5.2.2 Upon any Liquidation, after payment or provision for payment in full of the Series C Preference Amounts and the Series A Preference Amounts, the holders of the Series C Preferred Shares, the holders of the Series A Preferred Shares and the holders of shares of Common Stock shall be entitled to share in the distribution of the remaining assets of the Corporation pro rata based on the number of shares held by each such holder, treating for this purpose all securities held by such holder as if such securities had been converted to shares of Common Stock pursuant to the terms of this Restated Certificate immediately prior to such Liquidation. For purposes of clarity, the participation rights of the stockholders described in this Section 4.5.2.2 do not grant to the stockholders any additional participation rights to those participation rights described in Section 4.3.2.2.

4.5.2.4 In the event of a merger or other acquisition of the Corporation by another entity, the distribution date shall be deemed to be the date such transaction closes.

4.5.2.5. “Pre-Split Series C Purchase Price” Shall mean $0.50 per share.

4.5.4 Voting Rights.

In addition to the rights provided by law and the rights provided in Article 5 and Article 6, except as provided herein, the holders of the Series C Preferred Shares shall be entitled to vote on all matters as to which holders of shares of Common Stock shall be entitled to vote, in the same manner and with the same effect as such holders of shares of Common Stock, voting together with the holders of shares of Common Stock, the holders of Series A Preferred Shares and the holder of the Series B Preferred Share as one class. Each Series C Preferred Share shall entitle the holder thereof to such number of votes as shall equal the number of whole shares of Common Stock into which such Series C Preferred Share is then convertible pursuant to Section 4.5.5.

4.5.5 Optional Conversion.

4.5.5.1 Upon the terms set forth in this Section 4.5.5, each holder of Series C Preferred Shares shall have the right, at such holder’s option, at any time and from time to time, to convert any of such shares into the number of fully paid and non-assessable shares of Common Stock equal to the quotient obtained by dividing (i) the product of the Series C Purchase Price and the number of Series C Preferred Shares being converted, by (ii) the Series C Conversion Price (as defined below), as last adjusted and then in effect, by surrender of the certificates representing the Series C Preferred Shares to be converted. The initial conversion price per share at which shares of Common Stock shall be issuable upon conversion of Series C Preferred Shares shall be $5.25 (the “Series C Conversion Price”).

4.5.5.2 Any holder of Series C Preferred Shares may exercise the conversion right pursuant to Section 4.5.5.1 above, by delivering to the Corporation the certificate or certificates for the shares to be converted, duly endorsed or assigned in blank to the Corporation (if required by it), accompanied by written notice stating that the holder elects to convert such shares and stating the name or names (with address) in which the certificate or certificates for the shares of Common Stock are to be issued. Conversion shall be deemed to have been effected at the close of business on the date when such delivery is made (the “Series C Conversion Date”). As promptly as practicable thereafter, the Corporation shall issue and deliver to the place designated by such holder, a certificate or certificates for the number of full shares of Common Stock to which such holder is entitled, a cash amount in respect of any fractional interest in a share of Common Stock as provided in Section 4.5.5.3 below and the payment of any declared but unpaid dividends. The person in whose name the certificate or certificates for shares of Common Stock are to be issued shall be deemed to have become a stockholder of record on the applicable Series C Conversion Date unless the transfer books of the

Corporation are closed on that date, in which event such person shall be deemed to have become a stockholder of record on the next succeeding date on which the transfer books are open, but the Series C Conversion Price shall be that in effect on the Series C Conversion Date. Upon conversion of only a portion of the number of shares covered by a certificate representing Series C Preferred Shares surrendered for conversion, the Corporation shall issue and deliver to the holder of the certificate so surrendered for conversion, at the expense of the Corporation, a new certificate covering the number of such Series C Preferred Shares representing the unconverted portion of the certificate so surrendered.

4.5.5.3 Upon conversion, the Corporation shall not issue fractional shares of its Common Stock. The number of full shares of Common Stock issuable upon conversion of any Series C Preferred Shares shall be computed on the basis of the aggregate number of Series C Preferred Shares to be converted. If fractional shares of Common Stock are issuable, the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount equal to the product of (i) the price of one share of Common Stock as determined in good faith by the Board and (ii) such fractional interest, and, upon payment of such cash adjustment, the holders of fractional interests shall not be entitled to any rights as stockholders of the Corporation in respect of such fractional interests.

4.5.5.4 The Series C Conversion Price shall be subject to adjustment from time to time as follows:

(1) If the Corporation shall, at any time or from time to time after the date of original issuance of the first Series C Preferred Share (the “Series C Original Issuance Date”), issue any shares of Common Stock or other Equity Securities (as defined in Section 4.3.5.4(3)), other than Series C Excluded Stock (as defined below), allowing for the acquisition of shares of Common Stock without consideration or for a consideration per share less than the Series C Conversion Price for such Series C Preferred Shares in effect immediately prior to the issuance of such shares of Common Stock or Equity Securities (which in the case of Equity Securities other than shares of Common Stock shall include the consideration received by the Corporation upon issuance thereof and any consideration received by the Corporation in any intermediate exchange or exercise thereof for Equity Securities other than shares of Common Stock) then the Series C Conversion Price in effect immediately prior to such issuance shall forthwith be lowered to a price equal to the quotient obtained by dividing:

(A) an amount equal to the sum of (x) the total number of shares of Common Stock outstanding (including any shares of Common Stock deemed to have been issued pursuant to Section 4.5.5.4(2)(C) below) immediately prior to such issuance, multiplied by the Series C Conversion Price in effect immediately prior to such issuance, and (y) the aggregate consideration received by the Corporation upon such issuance; by

(B) the total number of shares of Common Stock outstanding (including any shares of Common Stock deemed to have been issued pursuant to Section 4.5.5.4(2)(C) below) immediately after the issuance of such shares of Common Stock.

(2) For the purposes of any adjustment of the Series C Conversion Price pursuant to Section 4.5.5.4(1) above, the following provisions shall be applicable:

4.5.5.4(1)(A) and 4.5.5.4(1)(B) above), if any, received by the Corporation upon the issuance of such options, warrants or rights plus the minimum purchase price provided in such options, warrants or rights for the shares of Common Stock covered thereby;

2. the aggregate maximum number of shares of Common Stock deliverable upon conversion or exercise of or in exchange for any such convertible, exercisable or exchangeable securities or upon the exercise of options or warrants to purchase or rights to subscribe for such convertible, exercisable or exchangeable securities and subsequent conversion, exercise or exchange thereof shall be deemed to have been issued at the time such securities, options, warrants or rights were issued and for a consideration equal to the consideration received by the Corporation for any such securities and related options, warrants or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options, warrants or rights (the consideration in each case to be determined in the manner provided in Sections 4.5.5.4(1)(A) and 4.5.5.4(1)(B) above);

3. on any change in the number of shares or exercise price of shares of Common Stock deliverable upon exercise of any such options, warrants or rights or conversion or exercise of or exchange for such securities, other than a change resulting from the anti-dilution provisions thereof, the Series C Conversion Price shall forthwith be readjusted to such Series C Conversion Price as would have obtained had the adjustment made upon the issuance of such options, warrants, rights or securities not converted, exercised or exchanged prior to such change or options, warrants or rights related to such securities not converted, exercised or exchanged prior to such change been made upon the basis of such change; and

4. on the expiration of any such options, warrants or rights, the termination of any such rights to convert,

exercise or exchange or the expiration of any options, warrants or rights related to such convertible, exercisable or exchangeable securities, the Series C Conversion Price shall forthwith be readjusted to such Series C Conversion Price as would have obtained had the adjustment made upon the issuance of such options, warrants, rights, securities or options, warrants or rights related to such securities been made upon the basis of the issuance of only the number of shares of Common Stock actually issued upon the exercise of such options, warrants or rights, upon the conversion or exchange of such securities, or upon the exercise of the options, warrants or rights related to such securities and subsequent conversion, exercise or exchange thereof.
