Item 2. Identity and Background

Item 2 of Schedule 13D is supplemented and superseded, as the case may be, as follows:

(e) As disclosed in the Issuer’s Current Report on Form 8-K filed with the SEC on September 3, 2014, the Issuer is, together with several of its affiliates and equity holders and certain other persons, including PCA, a defendant in securities litigation (the “Geveran Case”) brought by Geveran Investments Limited (“Geveran”), and on August 28, 2014, an Order Granting Plaintiff’s Motion for Partial Summary Judgment Under its First Cause of Action for Violation of the Florida Securities and Investment Protection Act (the “August 28 Order”) was granted by the Circuit Court of the Ninth Judicial Circuit in and for Orange County, Florida (the “Circuit Court”). The August 28 Order was entered on November 30, 2015, awarding Geveran, jointly and severally against each of the defendants, $25,000,000 as recessionary damages, prejudgment interest in the amount of $6,752,280, reasonable attorneys’ fees in the amount of $4,456,787.40 and taxable costs in the amount of $469,061.93, for a total recovery of approximately $36,678,129.33.

The Issuer stated in its Form 8-K filed with the SEC on September 3, 2014, that it believes that the Circuit Court’s partial summary judgment ruling in favor of Geveran was erroneous and that it intends to appeal it to the Florida Fifth District Court of Appeals. The Circuit Court has issued a temporary stay of the execution of the judgment to allow the defendants sufficient time to perfect an appeal seeking review of the August 28 Order. On December 7, 2015, the Issuer posted an appeal bond in support of its appeal of the August 28 Order.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of Schedule 13D is supplemented as follows:

The disclosure in Item 4 below is incorporated by reference herein.

Item 4. Purpose of Transaction

Item 4 of Schedule 13D is supplemented and superseded, as the case may be, as follows:

Series K Securities Issuance

On December 7, 2015, as contemplated by the previously disclosed Preferred Stock Subscription and Support Agreement (the “Subscription Agreement”) among Lighting Science Group Corporation (the “Issuer”), LSGC Holdings III and PPIV, and to facilitate support for the Appeal Bond (as defined below), the Issuer issued to PPIV 20,106.03 units of the Issuer’s securities (the “Series K Securities”), with each unit consisting of (a) one share of the Issuer’s Series K Preferred Stock (the “Series K Preferred Stock”) and (b) a warrant to purchase 735 shares of common stock of the Issuer in consideration of PPIV providing assistance to the Issuer with securing an appeal bond in the amount of up to $20,106,028.29 (the “Appeal Bond”) on the terms set forth in a General Indemnity Agreement and related side letter entered into by and among the Issuer, PPIV and the issuer of the Appeal Bond (the “Appeal Bond Agreements”). In total, the Issuer issued 20,106.03 shares of Series K Preferred Stock and a warrant to purchase 14,777,932 shares of the Issuer’s common stock (the “Appeal Bond Warrant”) to PPIV.

The Series K Preferred Stock has the designations, preferences, voting rights and other special rights set forth in the Certificate of Designation of Series K Preferred Stock (the “Series K COD”), which was filed as Exhibit 4.2 to the Issuer’s Form 8-K filed with the SEC on September 17, 2015. The Series K Preferred Stock is senior to the Issuer’s Series H Convertible Preferred Stock (the “Series H Preferred Stock”), the Issuer’s Series I Convertible Preferred Stock (the “Series I Preferred Stock”), the Series J Convertible Preferred Stock (the “Series J Preferred Stock”) and the Issuer’s common stock with respect to the payment of dividends and distribution of assets upon liquidation, dissolution or winding up of the Issuer. Depending on whether the Appeal Bond has been drawn or fully released, the Series K COD requires the Issuer to redeem the outstanding shares of Series K Preferred Stock in the event of a liquidation, dissolution or winding up of the Issuer or an earlier change of control or “junior security redemption,” which includes events triggering a redemption of the outstanding shares of Series H Preferred Stock, Series I Preferred Stock or Series J Preferred Stock.

As disclosed in Item 2(e) and in the Issuer’s Current Report on Form 8-K filed with the SEC on September 3, 2014, the Issuer is, together with several of its affiliates and equity holders and certain other persons, including PCA, a defendant in the Geveran Case. On November 30, 2015, the August 28 Order was entered. The Issuer posted the Appeal Bond in support of its appeal of the August 28 Order upon entry thereof and, pursuant to the Subscription Agreement, PPIV assisted the Issuer in securing the Appeal Bond.

Pursuant to the Subscription Agreement, the Issuer also agreed to commence a rights offering of the Series K Securities pursuant to which it will offer all holders of common stock and securities convertible into common stock (other than derivative securities issued pursuant to the Issuer’s equity-based compensation plan and employee stock purchase plan) the right to purchase a pro rata share of a like number of Series K Securities as the number issued to PPIV (the “Rights Offering”). The Series K Securities offered pursuant to the Rights Offering will be issued in exchange for a commitment from any exercising holder to fund an amount equal to the product obtained by multiplying (i) the number of Series K Securities to be acquired by such holder by (ii) $1,000, with such commitment to be payable when, as and if the Appeal Bond is drawn upon. If an exercising holder fails to fund its obligations in accordance with the terms of the Series K COD, PPIV will remain obligated to fund the applicable amount of the Appeal Bond. The Issuer agreed to use its reasonable best efforts to file and have declared effective a registration statement relating to the Rights Offering as soon as reasonably practicable after the entry of the August 28 Order.

Pursuant to the Series K COD, in the event of a claim on the Appeal Bond resulting in a payment by PPIV to the issuer of the Appeal Bond, such as a loss on appeal and collection of the bond amount from PPIV pursuant to the Appeal Bond Agreements, the outstanding shares of Series K Preferred Stock will be retained by the holders who have satisfied their obligations to fund their portion of the Appeal Bond in accordance with the terms of the Series K COD (the “Funding Series K Holders”). The Series K COD provides that, following the release or satisfaction in full of the commitments under the Appeal Bond, the Issuer will cancel for no additional consideration all of the shares of Series K Preferred Stock issued to PPIV and the Funding Series K Holders except a number of shares equal to the product of (x) the number of shares of Series K Preferred Stock held by such holder and (y) a fraction, the numerator of which is the aggregate amount of payments made by such holder with respect to funding the Appeal Bond and the denominator of which is the aggregate liquidation value (calculated by multiplying the number of shares held by such holder by $1,000) of such shares of Series K Preferred Stock, rounded down to the nearest whole share. In the event that the Issuer wins the appeal of the August 28 Order, upon the expiration or termination of the Appeal Bond, all shares of Series K Preferred Stock will be cancelled for no consideration.

The Appeal Bond Warrant will be exercisable beginning on the date that the Appeal Bond has been fully drawn or all commitments thereunder have been released and ending on the earlier of: (i) December 31, 2025, (ii) the date on which the Issuer consummates a Qualified Public Offering (as defined in the Appeal Bond Warrant), or (iii) the date of any Change of Control (as defined in the Appeal Bond Warrant). The Appeal Bond Warrant will be exercisable at an exercise price of $0.12 per share, subject to adjustments as provided in the Appeal Bond Warrant. PPIV and any Funding Series K Holders will retain the Appeal Bond Warrant(s) issued to such holders as consideration for their agreement to support the Appeal Bond regardless of whether such holders are required to make payments with respect to funding the Appeal Bond.

The Appeal Bond Warrant does not purport to be complete and is qualified in its entirety by reference to the full text of the Appeal Bond Warrant, which is filed as Exhibit 99.1, and is incorporated herein by reference.

The Reporting Persons continuously assess the Issuer’s business, financial condition, results of operations and prospects, general economic conditions, other developments and additional investment opportunities. Depending on such assessments, the Reporting Persons and/or their affiliates may acquire additional securities of the Issuer, including but not limited to common stock, existing preferred securities or new securities of the Issuer or may determine to purchase, sell or otherwise dispose of all or some of the Issuer’s securities in the open market, as applicable, in privately negotiated transactions, in transactions directly with the Issuer or otherwise. Such actions will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices, the financial condition, results of operations and prospects of the Issuer, alternative investment opportunities, general economic, financial market and industry conditions and other factors that the Reporting Persons and/or their affiliates may deem material to its investment decision. Also, the Reporting Persons and/or their affiliates have had and will continue to have discussions with management regarding the operations of the Issuer and matters of mutual interest, which could include the items in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Except as set forth herein and/or in previous amendments to this Schedule 13D, as the case may be, the Reporting Persons do not have present plans or proposals at this time that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

Item 5 of this Schedule 13D is hereby amended and restated in its entirety as follows:

(a) (b) Items 7 through 11 and 13 of each of the cover pages of this amended Schedule 13D are incorporated herein by reference. Such information is based on 211,756,727 shares of common stock outstanding as of November 10, 2015, according to the Issuer’s Form 10-Q filed with the SEC on November 13, 2015.

(c) The information in Item 4 is incorporated herein by reference.

In addition, on November 19, 2015, certain shares of restricted common stock of the Issuer previously granted by the Issuer’s Board of Directors (the “Board”) directly to Pegasus Capital Advisors IV, L.P. (“Pegasus Advisors IV”)

as director fees in respect of the service of Craig Cogut and Richard H. Davis, Jr. on the Issuer’s Board were cancelled in exchange for options to purchase the Issuer’s common stock that were granted directly to Pegasus Advisors IV. In exchange for options to purchase 451,238 shares of common stock of the Issuer, 200,000 shares of restricted common stock of the Issuer granted in respect of Mr. Cogut’s Board service were cancelled, and in exchange for options to purchase 541,485 shares of common stock of the Issuer, 240,000 shares of restricted common stock of the Issuer granted in respect of Mr. Davis’ Board service were cancelled. The options to purchase common stock of the Issuer will be exercisable on January 1, 2016 at an exercise price of $0.13 per share, and expire on November 19, 2025.

Because Mr. Cogut and Mr. Davis, each employees and/or partners, as the case may be, of Pegasus Advisors IV, serve on the Issuer’s Board as representatives of Pegasus Advisors IV and its affiliates, each of Mr. Cogut and Mr. Davis do not have a right to any of the Issuer’s securities issued as director fees and Pegasus Advisors IV is entitled to receive all director fees payable by the Issuer in respect of Mr. Cogut’s and Mr. Davis’ Board positions. All securities issued as director fees for Mr. Cogut’s and Mr. Davis’ Board service were accordingly issued directly to Pegasus Advisors IV. Pegasus Capital Advisors IV GP, L.L.C. (“Pegasus Advisors IV GP”) is the general partner of Pegasus Advisors IV and Mr. Cogut is the sole owner and managing member of Pegasus Advisors IV GP.

Except as set forth herein and/or in our previously filed amendments to Schedule 13D, as the case may be, there have been no other transactions in the class of securities reported on that were effected within the past 60 days.

(d) The disclosure regarding the relationship between the Reporting Persons in Item 2(f) of Amendment No. 39 to this Schedule 13D is incorporated by reference herein.

(e) N/A

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Section 2. Exercise of Warrant.

(a) This Warrant may be exercised, to the extent permitted by applicable laws and regulations, for Warrant Shares, in whole or in part, by the Holder registered on the books of the Company at any time during the Warrant Exercise Period. Any exercise of this Warrant shall be effected by:

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

(ii) payment to the Company of an amount equal to the Exercise Price multiplied by the number of Warrant Shares being purchased, (A) in cash or by wire transfer of immediately available funds or (B) by means of a cashless exercise pursuant to Section 2(d) (the foregoing methods of payment set forth in (A) and (B), including any combination of such methods, referred to herein as the “Payment”); and

(iii) the surrender at the principal office of the Company or to a nationally recognized courier for overnight delivery to the Company, simultaneously with or as soon as practicable following the delivery of the Exercise Notice and the Payment, of this

4

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 is reasonably satisfactory to the Company).

(b) The Company shall, not later than the fifth (5^th) Business Day (the “Delivery Date”) following receipt of an Exercise Notice, the Payment and this Warrant or the above-referenced indemnification in lieu of delivery of this Warrant (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 permitted designee, for the number of shares of Common Stock to which the Holder is entitled. On the date of 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 such Warrant Shares.

(c) 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 the right to purchase the number of Warrant Shares purchasable immediately prior to exercise, less the number purchased.

(d) In lieu of or in addition to exercising this Warrant and making the Payment in cash or by wire transfer pursuant to Section 2(a)(ii)(A), the Holder may elect to make the Payment by means of receiving shares of Common Stock equal to the value of this Warrant (or portion thereof being exercised) by delivery and surrender of the 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	equals the number of shares of Common Stock to be issued as Warrant Shares to the Holder;
Y	means, as of any date, the number of Warrant Shares purchasable (or portion thereof) under this Warrant that are being exercised at the applicable date of determination;
A	means, the Fair Market Value per share of Common Stock on the Trading Day immediately preceding the Exercise Date; and
B	the Exercise Price in effect as of the Trading Day immediately preceding the Exercise Date.

5

(e) No fractional shares of Common Stock or scrip representing fractional shares of Common Stock shall be issued upon any exercise of this Warrant. In lieu of any fractional share of Common Stock to which the Holder would otherwise be entitled, the Company shall issue a number of shares of Common Stock to the Holder rounded up to the nearest whole number of shares of Common Stock. No cash shall be payable to any Holder upon exercise of this Warrant

(f) In the event of any Change of Control of the Company, the Company shall send or cause to be sent to the Holder notice of such Change of Control at least five (5) days prior to the applicable record date or the applicable expected effective date of such Change of Control. Notwithstanding the definition of Warrant Exercise Period, to the extent that the Appeal Bond has not been fully drawn or the remaining commitments thereunder fully released, in the event of a Change of Control, prior to the consummation thereof, the Company shall make provisions for the surviving or resulting entity to assume all of the obligations of the Company under this Warrant, with all references to the Company herein becoming references to the surviving or resulting entity.

Section 3. Representations, Warranties, Covenants and Agreements. The Company hereby represents, warrants, covenants and agrees, as applicable, 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 shares of Common Stock issuable upon exercise of this Warrant will be duly authorized and when issued upon such exercise will be validly issued, fully paid and nonassessable and free from all taxes, liens (which term does not include any restrictions imposed by applicable securities laws) and charges with respect to the issue thereof.

(c) During the Warrant Exercise Period, the Company will have authorized and reserved at least the number of shares of Common Stock needed to provide for the exercise in full of the rights then represented by this Warrant.

(d) This Warrant and any Warrants in substitution for or in replacement of this Warrant and the Warrant Shares hereunder and thereunder are not and will not be subject to assessment and have not been and will not be issued in violation of any preemptive rights.

Section 4. Warrant Holder Not Deemed a Stockholder. Except as specifically provided in Section 2(b), 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 Common Stock of the Company for any purpose, (b) confer upon the Holder any of the rights of a stockholder of the Company or 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.

6

Section 5. Representations of Holder. The Holder, by the acceptance hereof, represents that it is acquiring this Warrant and, upon exercise, 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 the Holder cannot make such representations because they would be factually incorrect, it shall be a condition to the 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 the 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) Subject to this Section 6, this Warrant may only be transferred or assigned by the Holder to a transferee in a Permitted Transfer. 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 transfer tax, the Company shall, without charge, execute and deliver a new Warrant in the name of the transferee 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 Holder hereof.

(b) All transfers of this Warrant, or any shares of Common Stock issued upon exercise of this Warrant, must also be made in accordance with the Securities Act, and applicable state securities laws. Any attempted transfer of this Warrant, or any shares of Common Stock issued upon exercise of this Warrant, in violation of this Section 6 shall be null and void ab initio.

(c) 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.

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; provided; however, that in no event shall the Exercise Price be reduced below the par value per share of the shares of Common Stock issuable upon exercise of the Warrant. 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 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; provided; however, that in no event shall the Exercise Price be reduced below the par value per share of the shares of Common Stock issuable upon exercise of the Warrant.

Section 8. Covenant to Exchange. Upon the delivery of written notice to the Holder by the Company, Holder shall exchange this Warrant for a certificate (a “Warrant Certificate”) evidencing its right to purchase the Warrant Shares. The Warrant Certificate shall be subject to the terms of an agreement (the “Warrant Agreement”) administered by the Company or American Stock Transfer & Trust Company, LLC, as warrant agent, which Warrant Agreement shall contain terms equivalent in all material respects to the terms set forth in this Warrant.

Section 9. Registration Rights Agreement. The Company hereby acknowledges and affirms that the Holder shall have all rights set forth in that certain Amended and Restated Registration Rights Agreement, dated as of January 23, 2009, by and between the Company and Pegasus Partners IV, L.P., as amended by that certain Amendment No. 1 to Amended and Restated Registration Rights Agreement, dated as of May 25, 2012, by and between the Company and Pegasus Partners IV, L.P.

Section 10. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly, on receipt of an indemnification undertaking reasonably satisfactory to the Company (or, in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

8

Section 11. Notice. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Warrant must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by fax or email transmittal (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one Business Day after deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same.

Section 12. Amendment and Waiver. This Warrant may not be modified or amended except pursuant to an instrument in writing signed by the Company and the Holder. No provision hereunder may be waived other than in a written instrument executed by the waiving party.

Section 13. Termination. Notwithstanding the Warrant Exercise Period or anything herein to the contrary, this Warrant shall terminate upon default by such Holder of any payment obligation pursuant to such Holder’s Appeal Bond Obligation; provided, that if such default is cured within a period of ten Business Days from the continuation of such default, no termination shall occur.

Section 14. Governing Law. This Warrant shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

Section 15. Restrictive Legends. At all times this Warrant, and until such time as a registration statement has been declared effective by the U.S. Securities and Exchange Commission or the Warrant Shares may be sold pursuant to Rule 144 under the Securities Act without any restriction as to the number of securities that can then be immediately sold, certificates for any Warrant Shares will, in addition to any legend required under applicable securities law, bear a restrictive legend substantially in the form set forth on the first page of this Warrant.

Section 16. Lock-Up Provision. If the Holder is not otherwise subject to a registration rights or other agreement that restricts the transfer of equity securities held by such Holder in connection with an underwritten offering by the Company of its equity securities for sale to the public (or otherwise obligates to the Holder to enter into an agreement that has the same effect), the Holder agrees that in the event the Company proposes to offer for sale to the public any of its equity securities and such Holder is requested by the Company and any underwriter engaged by the Company in connection with such offering to sign an agreement restricting the sale or other transfer of Warrant Shares, then it will promptly sign such agreement and will not transfer, whether in privately negotiated transactions or to the public in open market transactions or otherwise, any Warrant Shares or other securities of the Company held by him or her during such period as is determined by the Company and the underwriters, not to exceed 180 days following the closing of the offering (such period, the “Lock-Up Period”). Such agreement shall be in writing and in form and substance reasonably satisfactory to the Company and such underwriter and pursuant to customary and prevailing terms and conditions. Notwithstanding whether the Holder has signed such an agreement, the Company may impose stop-transfer instructions with respect to the Warrant Shares or other securities of the Company subject to the foregoing restrictions until the end of the Lock-Up Period.
