EXERCISE OF WARRANT.




(a)Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(d)), this Warrant may be exercised by the Holder on any day on or after the Exercisability Date, in whole or in part (but not as to fractional shares), by delivery of a written notice (which may be by facsimile or email), in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant and payment to the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”) in cash or wire transfer of immediately available funds. The Holder shall not be required to surrender this Warrant in order to effect an exercise hereunder; provided, that in the event of an exercise of this Warrant for all Warrant Shares then issuable hereunder, this Warrant is surrendered to the Company’s transfer agent through DTC’s Deposit Withdrawal Agent Commission system (“DWAC System”) by the second (2nd) Trading Day following the date on which the Company’s transfer agent for the Common Stock and Warrants (“Transfer Agent”) has received the Exercise Notice. Within one (1) Trading Day following the date of exercise as aforesaid, the Holder shall deliver the Aggregate Exercise Price for the shares specified in the applicable Exercise Notice by wire transfer or cashier’s check drawn on a United States bank. No ink-original Exercise Notice shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Exercise Notice form be required, except as may be required by the Company’s transfer agent. On or before the first (1st) Trading Day following the date on which the Company or the Transfer Agent has received the Exercise Notice, the Company or the Transfer Agent shall transmit by email or facsimile an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the Transfer Agent. The Company or the Transfer Agent shall deliver any objection to the Exercise Notice on or before the first (1st) Trading Day following the date on which the Company or the Transfer Agent has received the Exercise Notice. In the event of any discrepancy or dispute, the records of the Company and the Transfer Agent shall be controlling and determinative in the absence of manifest error. On or before the earlier of (i) the third (3rd) Trading Day and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined below) following the date on which the Holder has delivered to the Company a duly completed and executed Exercise Notice (the “Share Delivery Date”), and the Aggregate Exercise Price, the Company or its Transfer Agent shall,

 



 

upon the request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with The Depository Trust Company (“DTC”) through its Deposit Withdrawal At Custodian system. Upon delivery of the Exercise Notice and the Aggregate Exercise Price, 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, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the book-entry accounts evidencing such Warrant Shares, as the case may be. The Company agrees to maintain a transfer agent that is a participant in the FAST Program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Principal Market with respect to the Common Stock as in effect on the date of delivery of the Exercise Notice.

 

If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Transfer Agent shall as soon as practicable and in no event later than ten (10) Trading Days after any exercise and at its own expense, issue a new Warrant (in accordance with Section 7(e)) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised, through the DWAC System. The Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant; provided, however, that the Company shall not be required to pay any tax which may be payable based on the income of the Holder or in respect of any transfer involved in the registration of any book-entry accounts for Warrant Shares or Warrants in a name other than that of the Holder or an affiliate thereof. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

 

If the Company shall fail for any reason or for no reason to credit the Holder’s balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant, then the Holder shall be entitled, but not required, to rescind the previously submitted Exercise Notice and the Company or the Transfer Agent shall return all consideration paid by Holder for such shares upon such rescission.

Notwithstanding anything herein to the contrary, the Company shall not be required to make any cash payments to the Holder in lieu of issuance of the Warrant Shares.

(b)Exercise Price. For purposes of this Warrant, “Exercise Price” means $13.20 per share of Common Stock (which takes into account the reverse stock split that the Company effected in January 2020), subject to adjustment as provided herein.


	
 
	
(c)
	
Reserved.




(d)Limitations on Exercises. Subject to the last sentence of this Section 1(d), the Company shall not effect the exercise of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Holder (together with such Holder’s affiliates and any other Persons acting as a group together) would beneficially own in excess of 9.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Proxy Statement, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, where such request indicates that it is being made pursuant to this Warrant, the Company shall within one (1) Trading Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of

 



 

outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. Upon delivery of a written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage as specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Warrants. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act. No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(d) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 1(d) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations set forth in this Section 1(d) shall not apply to exercises of this Warrant that occur prior to and expressly in connection with the Company’s consummation of a Fundamental Transaction.

(e)No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share that the Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price.

 

2.ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted from time to time as follows:

(a)Adjustment upon Subdivision or Combination of Shares of Common Stock. If the Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Issuance Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased. Any adjustment under this Section 2(a) shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)Other Adjustments. In the case of: (i) any recapitalization, reclassification or change of the Common Stock, (ii) any statutory share exchange, or (iii) similar transaction, in each case, other than Fundamental Transaction, and as a result of which the Common Stock is converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Change Event”), then, at and after the effective time of such Change Event, the right to exercise this Warrant into Warrant Shares shall be changed into a right to exercise such Warrant, with a proportional adjustment of the Exercise Price, into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock would have owned or been entitled to receive upon such Change Event.”

(c)Par Value. Notwithstanding anything to the contrary in this Warrant, in no event shall the Exercise Price be reduced below the par value of the Company’s Common Stock.

 

3.RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case:

(a)any Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of shares of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close of business on such record date, to a price determined by multiplying such Exercise Price by a fraction of which (i) the numerator shall be the Weighted Average Price of the shares of Common Stock on the

 



 

Trading Day immediately preceding such record date minus the value of the Distribution (as determined in good faith by the Company’s Board of Directors) applicable to one share of Common Stock, and (ii) the denominator shall be the Weighted Average Price of the shares of Common Stock on the Trading Day immediately preceding such record date; and

 

(b)the number of Warrant Shares shall be increased to a number of shares equal to the number of shares of Common Stock obtainable immediately prior to the close of business on the record date fixed for the determination of holders of shares of Common Stock entitled to receive the Distribution multiplied by the reciprocal of the fraction set forth in the immediately preceding paragraph (a).

 


	
 
	
4.
	
PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.




(a)Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time prior to the Expiration Date, the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to all of the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

 

(b)Fundamental Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless the successor entity or acquiring person, as the case may be (the “Buyer”), either (i) assumes in writing all of the obligations of the Company under this Warrant pursuant to a written instrument issued by the Buyer substantially similar in form and substance to this Warrant, including, without limitation, an adjusted Exercise Price and an adjusted number of Warrant Shares equivalent to the value of the Reference Property (calculated by the Company in good faith assuming full exercisability of this Warrant (e.g., without regard to any limitations on the exercise of this Warrant, including those set forth in Sections 1(d) and 5(b))) or (ii) agrees to deliver in connection with the closing of such Fundamental Transaction in exchange for the cancellation of each Warrant, Reference Property equal in value to the Black Scholes Value of the remaining unexercised portion of such Warrant (calculated by the Company in good faith assuming full exercisability of this Warrant (e.g. without regard to any limitations on the exercise of this Warrant, including those set forth in Sections 1(d) and 5(b))); provided that if the Fundamental Transaction causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property for which each Warrant will be exchanged will be deemed to be the weighted average of the types and amounts of consideration to be received by the holders of Common Stock. If Buyer is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market (a “Public Buyer”), whether clause 4(b)(i) or

(ii) will apply shall be at the option of the Buyer and the Company and if the Buyer is not a Public Buyer, at the option of the Buyer and Majority Holders. In the case of any assumption of this Warrant as set forth above, the Holder agrees to execute any and all agreements, in form and substance reasonably satisfactory to the Majority Holders, providing for such assumption.

 


	
 
	
5.
	
RESERVATION OF WARRANT SHARES.




(a)The Company covenants that it will at all times after the Exercisability Date reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of shares of Common Stock which are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive or any other contingent purchase rights of Persons other than the Holder (taking into account the adjustments and restrictions in Section 2). Such reservation shall comply without regard to the provisions of Section 1(d). The Company covenants that all shares of Common Stock so issuable and deliverable shall be, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, duly authorized, validly issued and fully paid and nonassessable. The Company will take all such actions as may be reasonably necessary to ensure that such shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common Stock may be listed.

 



 

(b)Following the Issuance Date, the Company covenants and agrees that it will use reasonable best efforts to obtain approval by the Company’s stockholders, at the first meeting of stockholders following the Issuance Date, which the Company shall use best efforts to hold as soon as practicable after the Issuance Date, but not later than 75 days from the Issuance Date (which shall be extended to 120 days from the Issuance Date in the event that the Company receives comments to the preliminary proxy statement for such meeting from the Securities and Exchange Commission), of an amendment to the Company’s certificate of incorporation increasing the aggregate number of authorized shares of Common Stock such that the Company shall have sufficient authorized but unissued and otherwise unreserved shares of Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, without regard to the provisions of Section 1(d) (the “Proposal”). The Company covenants and agrees that its Board of Directors shall unanimously recommend that the Proposal be approved by the Company’s stockholders at all meetings in which such Proposal is considered and promptly file the necessary amendments to the Company’s certificate of incorporation after the Proposal is approved. If the Company’s stockholders do not approve such Proposal at the first meeting in which it is voted on by stockholders, the Company covenants and agrees that it will submit the Proposal for approval of the Company’s stockholders at least annually until such approval is obtained.

 

6.WARRANT HOLDER NOT DEEMED A SHAREHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a shareholder 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, prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a shareholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

 


	
 
	
7.
	
REGISTRATION AND REISSUANCE OF WARRANTS.




(a)Registration of Warrant. The Company or its Transfer Agent shall register this Warrant, upon the records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time.
