OF

LIGHTING SCIENCE GROUP CORPORATION

To Be Designated

6% Convertible Preferred Stock

Pursuant to Section 151(g) of the

General Corporation Law of the State of Delaware

The undersigned DOES HEREBY CERTIFY that the following resolution was duly adopted by the Board of Directors of Lighting Science Group Corporation, a Delaware corporation (the “Corporation”), at a meeting duly convened and held, at which a quorum was present and acting throughout:

“RESOLVED, that pursuant to the authority conferred on the Board of Directors of the Corporation (the “Board of Directors”) by the Corporation’s Certificate of Incorporation, the issuance of a series of preferred stock, par value $0.001 per share, of the Corporation which shall consist of 2,656,250 shares of convertible preferred stock be, and the same hereby is, authorized; and the Chairman and Chief Executive Officer of the Corporation be, and he hereby is, authorized and directed to execute and file with the Secretary of State of the State of Delaware a Certificate of Designation of Preferred Stock of the Corporation fixing the designations, powers, preferences and rights of the shares of such series, and the qualifications, limitations or restrictions thereof (in addition to the designations, powers, preferences and rights, and the qualifications, limitations or restrictions thereof, set forth in the Certificate of Incorporation which may be applicable to the Corporation’s preferred stock), as follows:

1.Number of Shares; Designation. A total of 2,656,250 shares of preferred stock, par value $0.001 per share, of the Corporation are hereby designated as 6% Convertible Preferred Stock (the “Series”). Shares of the Series (“Preferred Shares”) will be issued pursuant to the terms of a Securities Purchase Agreement, dated as of May 10, 2005, by and among the Corporation and the Purchasers named therein (the “Purchase Agreement”). Capitalized terms used herein and not otherwise defined have the respective meanings set forth in the Purchase Agreement.

2.Rank. The Series shall, with respect to payment of dividends, redemption payments and rights upon liquidation, dissolution or winding-up of the affairs of the Corporation, rank:

(i) Senior and prior to theCommon Stock, par value $0.001 per share, of the Corporation (the “Common Stock”), and any additional series of preferred stock which may in the future be issued by the Corporation and are designated in the amendment to the Certificate of Incorporation or the certificate of designation establishing such additional preferred stock as ranking junior to the Preferred Shares. Any shares of the Corporation’s capital stock which are junior to the Preferred Shares with respect to the payment of dividends are hereinafter referred to as “Junior Dividend Shares” and any shares which are junior to the Preferred Shares with respect to redemption, payment and rights upon liquidation, dissolution or winding-up of the affairs of the Corporation are hereinafter referred to as “Junior Liquidation Shares”.

(ii) Pari passu with any additional series of preferred stock which may in the future be issued by the Corporation and are designated in the amendment to the Certificate of Incorporation or the certificate of designation establishing such additional preferred stock as ranking equal to the Preferred Shares or which do not state they are Junior Dividend Shares or Senior Dividend Shares (as defined below). Any shares of the Corporation’s capital stock which are equal to the Preferred Shares with respect to the payment of dividends are hereinafter referred to as “Parity Dividend Shares” and any shares which are equal to the Preferred Shares with respect to redemption, payment and rights upon liquidation, dissolution or winding-up of the affairs of the Corporation are hereinafter referred to as “Parity Liquidation Shares”.

(iii) Junior to any additional series of preferred stock which may in the future be issued by the Corporation and are designated in the amendment to the Certificate of Incorporation or the certificate of designation establishing such additional preferred stock as ranking senior to the Preferred Shares. Any shares of the Corporation’s capital stock which are senior to the Preferred Shares with respect to the payment of dividends are hereinafter referred to as “Senior Dividend Shares” and any shares which are senior to the Preferred Shares with respect to redemption, payment and rights upon liquidation, dissolution or winding-up of the affairs of the Corporation are hereinafter referred to as “Senior Liquidation Shares”.

The Corporation may not issue additional shares of preferred stock which are not (a) Junior Stock (as defined in paragraph 3(c) below) or (b) both Parity Liquidation Shares and Parity Dividend Shares without the consent of the holders of a majority of the Preferred Shares.

3.Dividends.

(a) The dividend rate on Preferred Shares shall be $0.192 per share per annum. Dividends on Preferred Shares shall be fully cumulative, accruing, without interest, from the date of original issuance of the Series through the date of redemption or conversion thereof, and, to the extent so declared by the Board of Directors, shall be payable in arrears on August 10, November 10, February 10 and May 10 of each year, commencing August 10, 2005, except that if such date is not a Business Day then to the extent so declared by the Board of Directors the dividend shall be payable on the first immediately succeeding Business Day (as used herein, the term “Business Day” shall mean any day except a Saturday, Sunday or day on which banking institutions are legally authorized to close in Dallas, Texas) (each such date being hereinafter referred to as a “Dividend Payment Date”). Dividends on the Preferred Shares shall be paid in cash; provided, however, if all of the Stock Payment Conditions are met on the applicable Dividend Payment Date and on each of the ten consecutive Trading Days immediately preceding such date (the applicable “Stock Payment Period”), the Corporation may pay such dividends, at the Corporation’s option, (i) in fully paid and nonassessable shares of Common Stock (such dividends paid in such form being herein called “PIK Dividends”) or (ii) in cash. PIK Dividends shall be paid by delivering to each record holder of Preferred Shares a number of shares of Common Stock (“PIK Dividend Shares”) determined by dividing (x) the total aggregate dollar amount of dividends accrued and unpaid with respect to Preferred Shares owned by such record holder on the record date for the applicable Dividend Payment Date (rounded to the nearest whole cent) by (y) the applicable PIK Dividend Price. In order to deliver PIK Dividend Shares in lieu of cash on a Dividend Payment Date, the Corporation must deliver, on or before the fifteenth (15^th) calendar day immediately prior to such date, written notice to each Holder of Preferred Shares stating that the Corporation wishes to do so (a “PIK Stock Dividend Notice”); in the event that the Corporation does not deliver a PIK Stock Dividend Notice on or before such fifteenth (15^th) day, the Corporation will be deemed to have elected to pay the related dividend in cash. Each Holder shall promptly thereafter deliver to the Corporation instructions designating whether such Holder wishes to receive delivery of its PIK Dividend Shares in physical certificates (and, if so, at what address) or through the Depository Trust Company (“DTC”), as long as no legend is required by the terms of the Purchase Agreement to be imprinted on such Shares (and, if so, the account number to be credited). If the Corporation wishes to deliver PIK Dividend Shares in lieu of cash with respect to accrued dividends, it must do so with respect to all (but not less than all) of such dividends. A PIK Stock Dividend Notice, once delivered by the Corporation, shall be irrevocable unless the Corporation ceases to satisfy all of the Stock Payment Conditions at any time after delivering such PIK Stock Dividend Notice, in which case such notice shall be deemed revoked and the dividend to which such notice relates shall be payable in cash on the Dividend Payment Date. The Corporation shall not issue fractional shares of Common Stock to which Holders may become entitled pursuant to this subparagraph, but in lieu thereof, the Corporation shall round the number of shares to be issued up to the next whole number. Each dividend shall be paid to the Holders of record of Preferred Shares as they appear on the stock register of the Corporation on the record date, not less than 10 nor more than 60 days preceding the applicable Dividend Payment Date, as shall be fixed by the Board of Directors. Dividends payable on each Dividend Payment Date shall be computed on the basis of a 360-day year of twelve 30-day months and rounded to the nearest cent. Dividends on account of arrearages for any past Dividend Payment Date may be declared and paid at any time, without reference to any scheduled Dividend Payment Date, to holders of record on such date, not exceeding 45 days preceding the payment date thereof, as may be fixed by the Board of Directors of the Corporation. Dividends shall accrue regardless of whether the Corporation has earnings, whether there are funds legally available therefor and/or whether declared. No interest shall be payable with respect to any dividend payment that may be in arrears. Holders of Preferred Shares called for redemption between the close of business on a dividend payment record date and the close of business on the corresponding Dividend Payment Date shall, in lieu of receiving such dividend on the Dividend Payment Date fixed therefor, receive such dividend payment on the date fixed for redemption together with all other accrued and unpaid dividends to the date fixed for redemption. The Holders shall not be entitled to any dividends other than the dividends provided for in this paragraph 3.

(b)No dividends, except as described in the next succeeding sentence, shall be declared or paid or set apart for payment on any Parity Dividend Shares for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and set aside for payment for all accrued dividends with respect to the Series through the most recent Dividend Payment Date ending on or prior to the date of payment. Unless dividends accrued and payable but unpaid on Preferred Shares and any Parity Dividend Shares at the time outstanding have been paid in full, all dividends declared by the Corporation upon Preferred Shares or Parity Dividend Shares shall be declared pro rata with respect to all such shares, so that the amounts of any dividends declared on Preferred Shares and the Parity Dividend Shares shall in all cases bear to each other the same ratio that, at the time of the declaration, all accrued but unpaid dividends on Preferred Shares and the other Parity Dividend Shares, respectively, bear to each other.

(c)If at any time the Corporation has failed to (x) pay or set apart for payment all accrued dividends on any Preferred Shares through the then most recent Dividend Payment Date and (y) set apart for payment an amount in cash equal to the scheduled dividend payments for each of the next two Dividend Payment Dates, the Corporation shall not, and shall not permit any corporation or other entity directly or indirectly controlled by the Corporation to:

(i) declare or pay or set aside for payment any dividend or other distribution on or with respect to any Junior Dividend Shares, whether in cash, securities, obligations or otherwise (other than dividends or distributions paid in shares of capital stock of the Corporation ranking junior to Preferred Shares both as to the payment of dividends and as to rights in liquidation, dissolution or winding-up of the affairs of the Corporation (“Junior Stock”), or options, warrants or rights to subscribe for or purchase shares of Junior Stock); or

(ii) redeem, purchase or otherwise acquire, or pay into, set apart money or make available for a sinking or other analogous fund for the redemption, purchase or other acquisition of, any Preferred Shares (unless all of the Preferred Shares are concurrently redeemed), Parity Dividend Shares, Parity Liquidation Shares or shares of Junior Stock for any consideration (except by conversion into or exchange for Junior Stock); provided, however, that this restriction shall not apply to the repurchase of shares of Common Stock from employees, officers, directors, consultants or other persons performing services for the Corporation or any subsidiary pursuant to agreements under which the Corporation has the option to repurchase such shares at cost or at cost plus interest at a rate not to exceed nine percent (9%) per annum, or, if lower than cost, at fair market value, upon the occurrence of certain events, such as the termination of employment; and provided further, that the total amount applied to the repurchase of shares of Common Stock shall not exceed $100,000 during any twelve month period, unless, in each such case, all dividends accrued on Preferred Shares through the most recent Dividend Payment Date and on any Parity Dividend Shares have been or contemporaneously are declared and paid in full.

(d)Any reference to “distribution” contained in this paragraph 3 shall not be deemed to include any distribution made in connection with any liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary.

4.Liquidation.

(a) The liquidation value per Preferred Share, in case of the voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Corporation, shall be an amount equal to $3.20, subject to adjustment in the event of a stock split, stock dividend or similar event applicable to the Series (the “Purchase Price”), plus an amount equal to the cash value of dividends accrued and unpaid thereon, whether or not declared, to the payment date (the “Liquidation Value”).

(b)In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Corporation (a “Liquidation Event”), the Holders (i) shall not be entitled to receive the Liquidation Value of the shares held by them until the liquidation value of all Senior Liquidation Shares shall have been paid in full, and (ii) shall be entitled to receive the Liquidation Value of such shares held by them in preference to and in priority over any distributions upon the Junior Liquidation Shares. Upon payment in full of the Liquidation Value to which the Holders are entitled, the Holders will not be entitled to any further participation in any distribution of assets by the Corporation. If the assets of the Corporation are not sufficient to pay in full the Liquidation Value payable to the Holders and the liquidation value payable to the holders of any Parity Liquidation Shares, the holders of all such shares shall share ratably in such distribution of assets in accordance with the amounts that would be payable on the distribution if the amounts to which the Holders and the holders of Parity Liquidation Shares are entitled were paid in full.

(c)For purposes of this paragraph 4, a Change of Control shall be treated as a Liquidation Event and shall entitle each Holder to receive, upon the consummation of such Change of Control, and at such Holder’s option, cash in an amount equal to the Liquidation Value of such Holder’s Preferred Shares.

(d)The Corporation shall, no later than the date on which a Liquidation Event occurs or is publicly announced, deliver in accordance with the notice provisions of the Purchase Agreement written notice of any Liquidation Event, stating the payment date or dates when and the place or places where the amounts distributable in such circumstances shall be payable, not less than 30 days prior to any payment date stated therein, to each Holder.

(e)Whenever the distribution provided for in this paragraph 4 shall be payable in securities or property other than cash, the value of such distribution shall be the fair market value of such securities or other property as determined in good faith by the Independent Directors.

5.Series Redemption. The Corporation shall redeem, from any source of funds legally available therefor, all outstanding Preferred Shares on May 10, 2010 (the “Series Redemption Date”). The Corporation shall effect such redemption on the Series Redemption Date by paying in cash in exchange for the Preferred Shares to be redeemed a sum equal to the Purchase Price of the Series plus all declared or accumulated but unpaid dividends on such shares.

6.Conversion.

(a)Right to Convert; Forced Conversion. Each Holder shall have the right to convert, at any time and from time to time after the Closing Date, all or any part of the Preferred Shares held by such Holder into such number of fully paid and non-assessable Conversion Shares as is determined in accordance with the terms hereof (a “Conversion”). In addition, if all of the Forced Conversion Conditions are met, the Corporation shall have the right, upon written notice delivered to each Holder (the “Forced Conversion Notice”), to cause all of the Holders to convert all (but not less than all) of their Preferred Shares into Conversion Shares. Upon a forced Conversion under this paragraph 6(a), the other provisions of this paragraph 6 shall apply as if such forced Conversion were a voluntary Conversion by all of the Holders.

(b)Conversion Notice. In order to convert Preferred Shares, a Holder shall send to the Corporation by facsimile transmission, at any time prior to 3:00 p.m., central time, on the Business Day on which such Holder wishes to effect such Conversion (the “Conversion Date”), a notice of conversion in substantially the form attached as Annex I hereto (a “Conversion Notice”), stating the number of Preferred Shares to be converted, the amount of dividends accrued (but remaining unpaid) thereon, and a calculation of the number of shares of Common Stock issuable upon such Conversion in accordance with the formula set forth in paragraph 6(c) below setting forth the basis for each component thereof, including the details relating to any adjustments made to the Conversion Price. The Holder shall promptly thereafter send the Conversion Notice and the certificate or certificates being converted to the Corporation. The Corporation shall issue a new certificate for Preferred Shares to the Holder in the event that less than all of the Preferred Shares represented by a certificate are converted; provided, however, that the failure of the Corporation to deliver such new certificate shall not affect the right of the Holder to submit a further Conversion Notice with respect to such Preferred Shares and, in any such case, the Holder shall be deemed to have submitted the original of such new certificate at the time that it submits such further Conversion Notice. Except as otherwise provided herein, upon delivery of a Conversion Notice by a Holder in accordance with the terms hereof, such Holder shall, as of the applicable Conversion Date, be deemed for all purposes to be the record owner of the Common Stock to which such Conversion Notice relates. In the case of a dispute between the Corporation and a Holder as to the calculation of the Conversion Price or the number of Conversion Shares issuable upon a Conversion (including, without limitation, the calculation of any adjustment to the Conversion Price following any adjustment thereof), the Corporation shall issue to such Holder the number of Conversion Shares that are not disputed within the time periods specified in paragraph 6(d) below and shall submit the disputed calculations to a certified public accounting firm of national reputation (other than the Corporation’s regularly retained accountants) within two (2) Business Days following the Corporation’s receipt of such Holder’s Conversion Notice. The Corporation shall cause such accountant to calculate the Conversion Price as provided herein and to notify the Corporation and such Holder of the results in writing no later than three (3) Business Days following the day on which such accountant received the disputed calculations (the “Dispute Procedure”). Such accountant’s calculation shall be deemed conclusive absent manifest error. The fees of any such accountant shall be borne by the party whose calculations were most at variance with those of such accountant.

(c)Number of Conversion Shares. The number of Conversion Shares to be delivered by the Corporation to a Holder pursuant to a Conversion shall be determined by dividing (i) the aggregate Liquidation Value of such Holder’s Preferred Shares to be converted by (ii) the Conversion Price in effect on the applicable Conversion Date.

(d)Delivery of Conversion Shares. The Corporation shall, no later than the close of business on the third (3^rd) Business Day following the later of the date on which the Corporation receives a Conversion Notice from a Holder by facsimile transmission pursuant to paragraph 6(b), above, and the date on which the Corporation receives the related Preferred Shares certificate (such third Business Day, the “Delivery Date”), issue and deliver or cause to be delivered to such Holder the number of Conversion Shares determined pursuant to paragraph 6(c) above (without any restrictive legend if permitted by the terms of the Purchase Agreement); provided, however, that any Conversion Shares that are the subject of a Dispute Procedure shall be delivered no later than the close of business on the third (3^rd) Business Day following the determination made pursuant thereto.

(e)Delivery Procedures. As long as the Corporation’s designated transfer agent (the “Transfer Agent”) participates in the DTC’s Fast Automated Securities Transfer program (“FAST”) and no restrictive legend is required pursuant to the terms of this Certificate of Designation or the Purchase Agreement, the Corporation shall effect delivery of Conversion Shares to the Holder by crediting the account of the Holder or its nominee at DTC (as specified in the applicable Conversion Notice) with the number of Conversion Shares required to be delivered, no later than the close of business on the applicable Delivery Date. In the event that the Transfer Agent is not a participant in FAST or if the Holder so specifies in its Conversion Notice or otherwise in writing on or before the Conversion Date, the Corporation shall effect delivery of Conversion Shares by delivering to the Holder or its nominee physical certificates representing such Conversion Shares, no later than the close of business on such Delivery Date. Conversion Shares delivered to the Holder shall not contain any restrictive legend unless such legend is required pursuant to the terms of the Purchase Agreement. If any Conversion would create a fractional Conversion Share, such fractional Conversion Share shall be disregarded and the number of Conversion Shares issuable upon such Conversion, in the aggregate, shall be the next closest number of Conversion Shares. 

(f)Failure to Deliver Conversion Shares.

(i) In the event that, for any reason, a Holder has not received certificates representing the number of Conversion Shares specified in the applicable Conversion Notice, without any restrictive legend (except to the extent a restrictive legend is required by the terms of the Purchase Agreement) on or before the Delivery Date therefor (a “Conversion Default”), and such failure to deliver certificates continues for two (2) Business Days following the delivery of written notice thereof from such Holder (such second Business Day following such written notice being referred to herein as the “Conversion Default Date”), the Corporation shall pay to such Holder payments (“Conversion Default Payments”) in the amount of (A) “N” multiplied by (B) the aggregate Liquidation Value of the Preferred Shares which are the subject of such Conversion Default multiplied by (C) one percent (1%), where “N” equals the number of days elapsed between the Conversion Default Date and the date on which all of the certificates representing such Conversion Shares (without any restrictive legend to the extent permitted by the terms of the Purchase Agreement) are issued and delivered to such Holder. Amounts payable hereunder shall be paid to the Holder in immediately available funds on or before the fifth (5^th) Business Day of the calendar month immediately following the calendar month in which such amounts have accrued.

(ii) In the event of a Conversion Default, a Holder may, upon written notice to the Corporation, regain on the date of such notice the rights of such Holder under the Preferred Shares that are the subject of such Conversion Default. In such event, such Holder shall retain all of such Holder’s rights and remedies with respect to the Corporation’s failure to deliver such Conversion Shares (including without limitation the right to receive the cash payments specified in paragraph 6(f)(i) above through the date of such written notice).

(iii) The Holders’ rights and remedies hereunder are cumulative, and no right or remedy is exclusive of any other. In addition to any other remedies provided herein, each Holder shall have the right to pursue actual damages for the Corporation’s failure to issue and deliver Conversion Shares timely after the applicable Delivery Date, including, without limitation, damages relating to any purchase of shares of Common Stock by or on behalf of such Holder in order to make delivery on a sale effected in anticipation of receiving Conversion Shares, such damages to be in an amount equal to (A) the aggregate amount paid by such Holder for the shares of Common Stock so purchased minus (B) the aggregate amount received by such Holder upon the sale of such Conversion Shares, and such Holder shall have the right to pursue all other remedies available to it at law or in equity (including, without limitation, a decree of specific performance and/or injunctive relief).

(g)Adjustments. The Conversion Price shall be subject to adjustment from time to time as follows:

(i) In the event that the Corporation shall (A) pay a dividend or make a distribution, in shares of Common Stock, on any class of Capital Stock of the Corporation or any subsidiary which is not directly or indirectly wholly owned by the Corporation, (B) split or subdivide its outstanding Common Stock into a greater number of shares, or (C) combine its outstanding Common Stock into a smaller number of shares, then in each such case the Conversion Price in effect immediately prior thereto shall be adjusted so that the holder of each share of the Series thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock that such holder would have owned or have been entitled to receive after the occurrence of any of the events described above had such share of the Series been converted immediately prior to the occurrence of such event. An adjustment made pursuant to this paragraph 6(g)(i) shall become effective immediately after the close of business on the record date in the case of a dividend or distribution (except as provided in paragraph 6(l) below) and shall become effective immediately after the close of business on the effective date in the case of such subdivision, split or combination, as the case may be. Any shares of Common Stock issuable in payment of a dividend shall be deemed to have been issued immediately prior to the close of business on the record date for such dividend for purposes of calculating the number of outstanding shares of Common Stock under clauses (ii) and (iii) below.

(ii) In the event that the Corporation shall issue or distribute New Securities, in any such case at a price per share less than $0.30 or that would entitle the holders of the New Securities to subscribe for or purchase shares of Common Stock at less than $0.30 per share (provided that the issuance of Common Stock upon the exercise of New Securities that are rights, warrants, options or convertible or exchangeable securities (“New Derivative Securities”) will not cause an adjustment in the Conversion Price if no such adjustment would have been required at the time such New Derivative Security was issued), then the Conversion Price in effect immediately prior thereto shall be adjusted so that the Conversion Price shall equal the price at which the Corporation issues or distributes such New Securities (or the price at which the holders of the New Securities are entitled to subscribe for or purchase shares of Common Stock). Each such adjustment shall be made successively whenever any such New Securities are issued. In determining whether any New Derivative Securities entitle the holders to subscribe for or purchase shares of Common Stock at less than $0.30 per share, there shall be taken into account any consideration received by the Corporation for such New Derivative Securities, the value of such consideration, if other than cash, to be determined in good faith by the Independent Directors, whose determination shall be conclusive and described in a certificate filed with the records of corporate proceedings of the Corporation. Notwithstanding the foregoing, in no event shall an adjustment be made under this clause (ii) if such adjustment would result in raising the then-effective Conversion Price.

(iii) No adjustment in the Conversion Price shall be required unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price then in effect; provided, however, that any adjustments that by reason of this paragraph 6(g)(iii) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this paragraph 6(g) shall be made to the nearest cent or nearest 1/100th of a share.

(iv) Notwithstanding anything to the contrary set forth in this paragraph 6(g), no adjustment shall be made to the Conversion Price upon any issuance that is not included within the definition of “New Securities” under Section 3.7 of the Purchase Agreement.

(v) The Corporation from time to time may reduce the Conversion Price by any amount for any period of time in the discretion of the Board of Directors.

(vi)   In the event that, at any time as a result of an adjustment made pursuant to paragraph 6(g)(i) through 6(g)(iii) above, the holder of any share of the Series thereafter surrendered for conversion shall become entitled to receive any shares of the Corporation other than shares of the Common Stock, thereafter the number of such other shares so receivable upon conversion of any share of the Series shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Stock contained in paragraphs 6(g)(i) through 6(g)(v) above, and the other provisions of this paragraph 6(g)(vi) with respect to the Common Stock shall apply on like terms to any such other shares.

(h)In case of any reclassification of the Common Stock (other than in a transaction to which paragraph 6(g)(i) applies), any consolidation of the Corporation with, or merger of the Corporation into, any other entity, any merger of another entity into the Corporation (other than a merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the Corporation), any sale or transfer of all or substantially all of the assets of the Corporation or any compulsory share exchange, pursuant to which share exchange the Common Stock is converted into other securities, cash or other property, then lawful provision shall be made as part of the terms of such transaction whereby the holder of each share of the Series then outstanding shall have the right thereafter, during the period such share shall be convertible, to convert such share only into the kind and amount of securities, cash and other property receivable upon the reclassification, consolidation, merger, sale, transfer or share exchange by a holder of the number of shares of Common Stock of the Corporation into which a share of the Series might have been converted immediately prior to the reclassification, consolidation, merger, sale, transfer or share exchange assuming that such holder of Common Stock failed to exercise rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon consummation of such transaction, subject to adjustment as provided in paragraph 6(g) above following the date of consummation of such transaction. As a condition to any such transaction, the Corporation or the person formed by the consolidation or resulting from the merger or which acquires such assets or which acquires the Corporation’s shares, as the case may be, shall make provisions in its certificate or articles of incorporation or other constituent document to establish such right. The certificate or articles of incorporation or other constituent document shall provide for adjustments which, for events subsequent to the effective date of the certificate or articles of incorporation or other constituent document, shall be as nearly equivalent as may be practicable to the adjustments provided for in this paragraph 6. The provisions of this paragraph 6(h) shall similarly apply to successive reclassifications, consolidations, mergers, sales, transfers or share exchanges.

(i)If:

(i)  the Corporation shall take any action which would require an adjustment in the Conversion Price pursuant to Section 6(g); or

(ii) the Corporation shall authorize the granting to the holders of its Common Stock generally of rights, warrants or options to subscribe for or purchase any shares of any class or any other rights, warrants or options; or

(iii) there shall be any reclassification or change of the Common Stock (other than a subdivision or combination of its outstanding Common Stock or a change in par value) or any consolidation, merger or statutory share exchange to which the Corporation is a party and for which approval of any stockholders of the Corporation is required, or the sale or transfer of all or substantially all of the assets of the Corporation; or

(iv) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Corporation;

then, the Corporation shall cause to be filed with the transfer agent for the Series and shall cause to be delivered to each Holder in accordance with the notice provisions of the Purchase Agreement, as promptly as possible, but at least 20 days prior to the applicable date hereinafter specified, a notice stating (A) the date on which a record is to be taken for the purpose of such dividend, distribution or granting of rights, warrants or options or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights, warrants or options are to be determined, or (B) the date on which such reclassification, change, consolidation, merger, statutory share exchange, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, change, consolidation, merger, statutory share exchange, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in this paragraph 6(i).

(j)Whenever the Conversion Price is adjusted as herein provided, the Corporation shall promptly file with the transfer agent for the Series a certificate of an officer of the Corporation setting forth the Conversion Price after the adjustment and setting forth a brief statement of the facts requiring such adjustment and a computation thereof. The Corporation shall promptly cause a notice of the adjusted Conversion Price to be delivered to each Holder.

(k)In any case in which paragraph 6(g) provides that an adjustment shall become effective immediately after a record date for an event and the date fixed for such adjustment pursuant to paragraph 6(g) occurs after such record date but before the occurrence of such event, the Corporation may defer until the actual occurrence of such event issuing to the holder of any Preferred Shares converted after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment.

(l)In case the Corporation shall take any action affecting the Common Stock, other than actions described in this paragraph 6, which in the opinion of the Board of Directors would materially adversely affect the conversion right of the Holders, the Conversion Price may be adjusted, to the extent permitted by law, in such manner, if any, and at such time, as the Board of Directors may determine to be equitable in the circumstances; provided, however, that in no event shall (i) the Board of Directors be required to take any such action and (ii) any such action result in an increase in the Conversion Price.

(m)The Corporation shall list the shares of Common Stock required to be delivered upon conversion of Preferred Shares, prior to delivery, upon each national securities exchange or any similar system of automated dissemination of securities prices, if any, upon which the Common Stock is listed at the time of delivery.

7.Status of Shares. All Preferred Shares that are at any time redeemed or converted pursuant to paragraph 5 or 6 above, and all Preferred Shares that are otherwise reacquired by the Corporation and subsequently canceled by the Board of Directors, shall be retired and shall not be subject to reissuance.

8.Voting Rights. Each holder of shares of the Series shall be entitled to the number of votes equal to the number of shares of Common Stock into which such shares of the Series could be converted and shall have voting rights and powers equal to the voting rights and powers of the Common Stock (except as otherwise expressly provided herein or as required by law), voting together with the Common Stock as a single class and shall be entitled to notice of any stockholders’ meeting in accordance with the Bylaws of the Corporation. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the above formula (after aggregating all shares into which shares of the Series held by each holder could be converted) shall be rounded to the nearest whole number (with one-half being rounded upward).

9.Restrictions and Limitations. So long as any Preferred Shares remain outstanding, the Corporation, shall not, without the vote or written consent by the holders of at least a majority of the outstanding Preferred Shares, voting together as a single class:

(i) Redeem, purchase or otherwise acquire for value (or pay into or set aside for a sinking or other analogous fund for such purpose) any share or shares of its Capital Stock, except for (a) a transaction in which all outstanding shares of preferred stock are concurrently redeemed, purchased or otherwise acquired, (b) conversion into or exchange for Junior Stock, or (c) redemption in accordance with paragraph 5 hereof; provided, however, that this restriction shall not apply to the repurchase of shares of Common Stock from employees, officers, directors, consultants or other persons performing services for the Corporation or any subsidiary pursuant to agreements under which the Corporation has the option to repurchase such shares at cost or at cost plus interest at a rate not to exceed nine percent (9%) per annum, or, if lower than cost, at fair market value, upon the occurrence of certain events, such as the termination of employment; and provided further, that the total amount applied to the repurchase of shares of Common Stock shall not exceed $100,000 during any twelve month period;

(ii)alter, modify or amend the terms of the Series in any way;

(iii) create any new series or class of capital stock having a preference over the Series as to payment of dividends, redemption or distribution of assets upon a Liquidation Event or any other liquidation, dissolution or winding up of the Corporation;

(iv)increase the authorized number of shares of the Series;

(v) re-issue any Preferred Shares which have been converted or redeemed in accordance with the terms hereof;
