(i) delivery of a written notice, in the form attached as Exhibit A (the “Exercise Notice”), of Holder’s election to exercise this Warrant, specifying the number of Warrant Shares to be purchased;

3

(ii) payment to the Company of an amount equal to the Exercise Price multiplied by the number of Warrant Shares being purchased (1) in cash or wire transfer of immediately available funds; (2) by means of a cashless exercise pursuant to Section 2(c); (3) by surrender of all or a portion (as appropriate) of such Holder’s Series D Preferred Shares pursuant to Section 2(d); or (4) following the redemption of the Holder’s Series D Preferred Shares, by applying the Exercise Price Accrual credited to the account of such Holder pursuant to Section 2(e) (the foregoing methods set forth in (1) through (4) of this Section 2(a)(ii) referred to herein as the “Payment,” and any Payment may include any combination of such methods); and

(iii) the surrender at the principal office of the Company or to a nationally recognized courier for overnight delivery to the Company, as soon as practicable following such date, of this Warrant, (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction in such form and substance as reasonably satisfactory to the Company).

The Company shall, not later than the fifth Business Day (the “Delivery Date”) following receipt of an Exercise Notice, the Payment and this Warrant or such indemnification (collectively, the “Exercise Documents”), arrange for its transfer agent, on or before the Delivery Date, to issue and surrender to a nationally recognized courier for overnight delivery to the address specified in the Exercise Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled. Upon delivery of the Exercise Notice and the Payment (the “Exercise Date”), the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised on the Delivery Date, irrespective of the date of delivery of the certificates evidencing the Warrant Shares.

(b) Unless the rights represented by this Warrant have expired or been fully exercised, the Company shall, as soon as practicable and in no event later than five Business Days after receipt of the Exercise Documents and at its own expense, issue a new Warrant identical in all respects to this Warrant, except it shall represent rights to purchase the number of Warrant Shares purchasable immediately prior to exercise, less the number purchased.

(c) In lieu of or in addition to exercising this Warrant by means of paying via cash or wire transfer or pursuant to Section 2(d) or Section 2(e), the Holder may elect to make the Payment by means of receiving shares equal to the value of this Warrant (or portion thereof being exercised) by delivery and surrender of this Warrant together with the Exercise Notice in accordance with the terms hereof, duly completed to indicate a net issuance exercise and executed by the Holder, in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

X = Y(A-B)/A

where X  =  the number of shares issued to the Holder;

4

(d) In lieu of or in addition to exercising this Warrant by means of paying via cash or wire transfer or pursuant to Section 2(c), the Holder may elect to make the Payment by surrender of Series D Preferred Shares. In such case, the Holder shall surrender the number of Series D Preferred Shares, properly endorsed to the Company, having an aggregate Liquidation Value (as defined in the Series D Certificate) equal to the Payment as calculated pursuant to Section 2(a) (less any amounts paid via cash or wire transfer or pursuant to Section 2(c)). Unless all of the shares represented by the certificate for the Series D Shares have been surrendered, the Company shall, as soon as practicable and in no event later than five Business Days after receipt of the Exercise Documents and at its own expense, issue a new certificate representing the remaining Series D Shares owned by the Holder.

(e) If this Warrant is exercised following the redemption of the Holder’s Series D Preferred Shares, then in lieu of or in addition to exercising this Warrant by means of paying via cash or wire transfer or pursuant to Section 2(c), the Holder may elect to make the Payment by applying that amount of the Exercise Price Accrual credited to the account of such Holder equal to the Payment as calculated pursuant to Section 2(a) (less any amounts paid via cash or wire transfer or pursuant to Section 2(c)). Any amount of the Exercise Price Accrual applied upon such exercise shall be deemed to have been surrendered by such Holder to the Company.

(f) No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock issued shall be rounded up or down to the nearest whole number.

Section 3. Covenants as to Common Stock. The Company hereby covenants and agrees as follows:

(a) This Warrant is, and any Warrants issued in substitution for or in replacement of this Warrant upon issuance will be, duly authorized, executed and delivered.

(b) All Warrant Shares upon issuance will be validly issued, fully paid and nonassessable and free from all liens and charges with respect to the issue thereof.

(c) As long as this Warrant may be exercised, the Company will have authorized and reserved at least the number of shares of Common Stock needed to provide for the exercise of the rights then represented by this Warrant and any other Derivative Security then outstanding.

Section 4. Warrant Holder Not Deemed a Stockholder. Except as specifically provided in Section 2(a), nothing contained in this Warrant shall be construed to (a) grant the Holder any rights to vote or receive dividends or be deemed the holder of shares of the Company for any purpose, (b) confer upon the Holder any of the rights of a stockholder of the Company or

5

any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, or (c) impose any liabilities on the Holder to purchase any securities or as a stockholder of the Company, whether asserted by the Company or creditors of the Company, prior to the issuance of the Warrant Shares.

Section 5. Representations of Holder. The Holder, by the acceptance hereof, represents that it is acquiring this Warrant and the Warrant Shares for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution of this Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities Act. Upon exercise of this Warrant, the Holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Warrant Shares are being acquired solely for the Holder’s own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale. If Holder cannot make such representations because they would be factually incorrect, it shall be a condition to Holder’s exercise of this Warrant that the Company receive such other representations as the Company considers reasonably necessary to assure the Company that the issuance of its securities upon exercise of this Warrant shall not violate any federal or state securities laws. The Company shall not be penalized or disadvantaged by a Holder’s inability to exercise this Warrant due to its inability to make the required representations in connection with the exercise of this Warrant.

Section 6. Ownership and Transfer.

(a) The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof), a register for this Warrant, in which the Company shall record the name and address of the Person in whose name this Warrant has been issued, as well as the name and address of each transferee who has acquired this Warrant in accordance with applicable law and the terms of this Warrant. The Company may treat the Person in whose name this Warrant is registered on the register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant.

(b) This Warrant may only be offered, sold, transferred or assigned in compliance with the Securities Act and applicable state securities laws. From the Issuance Date until the redemption of the Holder’s Series D Preferred Shares, this Warrant may only be offered, sold, transferred or assigned in conjunction with the sale, transfer or assignment of whole Units only; provided, that any such sale, transfer of assignment must consist of at least 25,000 Units. Any time after the redemption of the Holder’s Series D Preferred Shares, this Warrant may only be offered, sold, transferred or assigned in conjunction with the sale, transfer or assignment of the Exercise Price Accrual associated therewith. Any attempted transfer of this Warrant in violation of this Section 6(b) shall be null and void ab initio.

(c) Subject to the terms of this Section 6, upon surrender of this Warrant to the Company at its principal office or at the office of its transfer agent, if any, with the Assignment Form annexed hereto as Exhibit B duly executed and funds sufficient to pay any

6

transfer tax, the Company shall, without charge, execute and deliver a new Warrant in the name of the assignee evidencing the portion of the Warrant certificate so transferred and a new Warrant certificate evidencing the remaining portion of the Warrant certificate not so transferred, if any, shall be issued to the transferring Holder. The delivery of the new Warrant certificate by the Company to the transferee thereof shall be deemed to constitute acceptance by such transferee of all of the rights and obligations of a holder of a Warrant certificate. Subject to the terms of this Section 6, this Warrant may be divided or combined with other warrants which carry the same rights upon presentation hereof at the principal office of the Company together with a written notice specifying the names and denominations in which new Warrants are to be issued and signed by the Warrant Holder hereof.

Section 7. Adjustment of Exercise Price and Number of Shares. The Exercise Price and the number of Warrant Shares shall be adjusted from time to time as follows:

(a) Stock Splits. If the Company subdivides (by any stock split, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to the subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company combines (by combination, reverse stock split or otherwise) its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to the combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased. Any adjustment under this Section 7(a) shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b) Stock Dividends. If the Company declares a dividend or any other distribution upon the Common Stock (other than the Rights Offering) that is payable in shares of Common Stock or Derivative Securities, the number of Warrant Shares will be proportionately increased and the Exercise Price in effect immediately prior to the declaration of the dividend or distribution will be reduced to the quotient obtained by dividing (i) the number of shares of Common Stock outstanding immediately prior to the declaration multiplied by the then effective Exercise Price by (ii) the total number of shares of Common Stock outstanding immediately after the declaration (assuming the exercise or conversion of any such Derivative Securities for cash (not on a “cashless” basis)).

(c) Adjustment for Property Dividends. If the Company declares a dividend or any other distribution upon the Common Stock that is payable in any of its assets (including cash) or debt securities or any rights, options or warrants to purchase debt securities, assets or other securities of the Company (other than (i) Common Stock pursuant to which another provision of this Section 7 applies or (ii) any dividend or distribution upon a merger or consolidation or sale to which Section 8 applies) (a “Property Dividend”), then and in each such event the Exercise Price for this Warrant in effect immediately prior to the close of business on the date for the determination of the holders of Common Stock entitled to receive such dividend or distribution shall be decreased by the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive and evidenced by a Board Resolution filed with the Company) of such Property Dividend so distributed for each share of Common Stock.

7

Any adjustment under this Section 7(c) shall, become effective immediately prior to the opening of business on the day after the date for the determination of the holders of Common Stock entitled to receive Property Dividend. If the Board of Directors determines the fair market value of any Property Dividend for purposes of this Section 7(c) by reference to the actual or when issued trading market for any securities comprising such Property Dividend, it must in doing so consider the prices in such market over the same period used in computing the Fair Market Value (pursuant to Section 7(e)) per share of Common Stock.

For purposes of clarity, if a declared Property Dividend would have reduced the Exercise Price to an amount below $0, the Exercise Price will be reduced to $0 and any remaining fair market value of the Property Dividend that would have resulted in a reduction of the Exercise Price below $0 shall be reflected in an increase of the number of shares issuable upon exercise of this Warrant pursuant to Section 7(d) hereto.

(d) Adjustment for Property Dividend In Special Circumstances. In the event that the Exercise Price is or has been reduced to $0 or a price that rounds to $0 due to adjustments to the Exercise Price pursuant to Section 7(c) and the Company declares a dividend or any other distribution upon the Common Stock that is a Property Dividend, this Section 7(d) shall apply and the number of shares of Common Stock issuable upon exercise of the Warrant shall be adjusted in accordance with the formula:

N’ = N x     M    

                M - F

The adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of stockholders entitled to receive such distribution.

This Section 7(d) does not apply to regular quarterly cash dividends. If any adjustment is made pursuant to this Section 7(d) as a result of the issuance of rights, options or warrants and at the end of the period during which any such rights, options or warrants are exercisable, not all such rights, options or warrants shall have been exercised, this Warrant shall be immediately readjusted as if “F” in the above formula was the fair market value on the ex date

8

for such distribution of the indebtedness or assets actually distributed upon exercise of such rights, options or warrants divided by the number of shares of Common Stock outstanding on the ex-dividend date for such distribution. Notwithstanding anything to the contrary contained in this Section 7(d), if “M-F” in the above formula is less than $1.00, the Company may elect to, and if “M-F” or is a negative number, the Company shall, in lieu of the adjustment otherwise required by this Section 7(d), distribute to the holder of this Warrant, upon exercise thereof, the evidences of indebtedness, assets, rights, options or warrants (or the proceeds thereof) which would have been distributed to such holder had this Warrant been exercised (for cash) immediately prior to the record date for such distribution.

“Closing Price” on any date of determination means (i) the closing sale price for the regular trading session (without considering after hours or other trading outside regular trading session hours) of the Common Stock (regular way) as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is listed, (ii) if the Common Stock is not so reported, the last quoted bid price for the Common Stock in the over-the-counter market as reported by the OTC Bulletin Board, the National Quotation Bureau or similar organization, or (iii) if the Common Stock is not so quoted, the average of the mid-point of the last bid and ask prices for the Common Stock from at least three nationally recognized investment banking firms that the Company selects for this purpose.

“ex date” means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Quoted Price was obtained without the right to receive such issuance or distribution.

“Trading Day” means each Monday, Tuesday, Wednesday, Thursday and Friday, other than any day on which securities are not traded on the applicable securities exchange or in the applicable securities market.

(e) Issuance of Common Stock Below Current Fair Market Value. If the Company shall issue or sell shares of Common Stock, or Derivative Securities containing the right to subscribe for or purchase shares of Common Stock to someone other than the Holder, at a price per share (determined, in the case of such Derivative Securities, by dividing (A) the total amount receivable by the Company in consideration of the issuance and sale of such Derivative Securities, plus the total consideration, if any, payable to the Company upon exercise, conversion or exchange thereof, by (B) the total number of shares of Common Stock covered by such Derivative Securities) that is lower than the then current Fair Market Value per share of Common Stock in effect immediately prior to such sale or issuance, then (1) the number of Warrant Shares thereafter issuable upon the exercise of this Warrant shall be increased by adding the number of Warrant Shares theretofore issuable upon exercise of this Warrant to the product of (x) the Cheap Stock Issued (defined below), multiplied by (y) the Ownership Ratio (defined below); and (2) the Exercise Price shall be reduced by multiplying the then current Exercise Price by a fraction of which, the numerator shall be the number of Warrant Shares issuable immediately prior to such sale or issuance and the denominator of which shall be the number of Warrant Shares issuable after adjustment pursuant to clause (1), above. Such adjustment shall be made successively whenever any such sale or issuance is made.

9

“Cheap Stock Issued” shall be the number of additional shares of Common Stock issued or offered by the Company for subscription or purchase as described above minus the number of shares of Common Stock that the aggregate offering price of the total number of shares of Common Stock so offered would purchase at the then current Fair Market Value per share of Common Stock.

“Ownership Ratio” shall be a fraction, the numerator of which shall be the number of Warrant Shares prior to such time issuable upon exercise of this Warrant, and the denominator of which shall be the number of shares of Common Stock then outstanding on the date of issuance or sale of such shares of Common Stock or such Derivative Securities. For purposes of such adjustments, the shares of Common Stock which the holder of any such Derivative Securities shall be entitled to subscribe for or purchase (assuming the exercise or conversion of any such Derivative Securities for cash (not on a “cashless” basis)) shall be deemed to be issued and outstanding as of the date of the sale and issuance of the rights, warrants or convertible or exchangeable securities.

“Fair Market Value” shall be equal to a discount of 10% to the average VWAP of the Common Stock for the thirty days preceding the issuance of such shares of Common Stock, or Derivative Securities.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted for trading as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time); (b) if the OTC Bulletin Board is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board; (c) if the Common Stock is not then quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the “Pink Sheets” published by Pink Sheets, LLC (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported; or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holder and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“Trading Market” means the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the American Stock Exchange, The Nasdaq Capital Market, The Nasdaq Global Market, The Nasdaq Global Select Market, the New York Stock Exchange or the OTC Bulletin Board.

(f) Other Adjustments.

(i) Notwithstanding anything to the contrary contained in this Section 7, if, at any time while this Warrant is outstanding, the Company shall issue or sell shares of Common Stock, or Derivative Securities to someone other than the Holder, at a price per share (determined, in the case of such Derivative Securities, by dividing (A) the total amount

10

receivable by the Company in consideration of the issuance and sale of such Derivative Securities, plus the total consideration, if any, payable to the Company upon exercise, conversion or exchange thereof, by (B) the total number of shares of Common Stock covered by such Derivative Securities) that is lower than the Exercise Price, the Company shall adjust the Exercise Price and number of shares into which this Warrant is convertible so that this Warrant shall be exercisable for the same percentage of the outstanding Common Stock (on an “as converted” basis) following the issuance or sale of such other shares of Common Stock or Derivative Securities for the same aggregate consideration prior to such adjustment; provided, that such adjustments shall only be made for the benefit of the Holder of this Warrant.

(ii) Notwithstanding anything to the contrary contained in this Section 7, if, at any time while this Warrant is outstanding, the number of shares underlying any Derivative Security, and/or the exercise or conversion price of such Derivative Security adjusts or would have adjusted for any reason (including as a result of the issuance of this Warrant) and the terms, manner or method of such adjustment are more favorable than the adjustment provisions contained in this Section 7, the Company shall adjust the Exercise Price and/or number of shares into which this Warrant is convertible in order to give the Holder the benefit of the more favorable terms, manner and/or method; provided, that no adjustment shall be made pursuant to this Section 7(f)(ii): (A) if an adjustment is otherwise required pursuant to another provision contained in this Section 7; (B) if the additional adjustment that may be required by this Section 7(f)(ii) would not require a decrease or increase of at least 1% in the Exercise Price then in effect or the number of Warrant Shares for which this Warrant is then exercisable; or (C) solely as a result of an adjustment pursuant to Section 7(f) of those certain warrants to purchase Common Stock each dated December 31, 2008 and issued to purchasers of shares of Series C Preferred Stock of the Company in connection with the purchase of such shares of Series C Preferred Stock. For the avoidance of doubt, the Exercise Price and number of Warrant Shares issuable shall be adjusted so that this Warrant shall be exercisable for the same percentage of the outstanding Common Stock (on a fully diluted basis) following the adjustment of such other Derivative Security pursuant to the foregoing sentence for the same aggregate consideration prior to such adjustment; provided, that following such adjustment, if the exercise price of such other Derivate Security is less than the Exercise Price, the Exercise Price shall be reduced to the same exercise price as the Derivative Security; provided further, that such adjustments shall only be made for the benefit of the Holder of this Warrant.

(g) Section 7(e) and Section 7(f)(i) shall not apply to: (i) securities issued to employees, officers, directors, consultants or other service providers of the Company pursuant to a plan or agreement approved by the board of directors, including the Lighting Science Group Corporation Amended and Restated Equity-Based Compensation Plan, (ii) securities issued to settle the Company’s directors’ fees, (iii) securities issued pursuant to the exercise or conversion of currently issued Derivative Securities, restricted stock, or other derivative instruments of the Company, (iv) securities issued as a dividend on preferred stock of the Company, and (v) securities issued pursuant to an acquisition of shares or assets of a target company at a value not less than the fair market value as determined by an independent investment banking firm.

(a) Upon the consummation of any (i) sale of all or substantially all of the Company’s assets to an acquiring Person or (ii) other Change of Control following which the Company is not a surviving entity, the Company will secure from the Person purchasing the assets or the successor resulting from the Change of Control (in each case, the “Acquiring Entity”) a written agreement to deliver to Holder in exchange for this Warrant, a security of the Acquiring Entity evidenced by a written instrument substantially similar in form and substance to this Warrant and reasonably satisfactory to the Holder. Prior to the consummation of any other Change of Control, the Company shall make appropriate provision to insure that Holder will thereafter have the right to acquire and receive in lieu of the shares of Common Stock immediately theretofore acquirable and receivable upon the exercise of this Warrant, such shares of stock, securities or assets that would have been issued or payable in the Change of Control with respect to or in exchange for the number of Warrant Shares that would have been acquirable as of the date of the Change of Control.

Section 9. Lost, Stolen, Mutilated or Destroyed Warrant.
