Form of Warrant Agreement



 Exhibit 4.4 
 WARRANT AGREEMENT 
 This Warrant Agreement
(“Warrant Agreement”) is made as of             , 2010, by and between Vringo, Inc., a Delaware corporation, (the “Company”), and American Stock
Transfer & Trust Company (the “Warrant Agent”). 
 WHEREAS, the Company is engaged in a public
offering (the “Public Offering”) of 2,760,000 units (the “Units”) of the Company (including 360,000 additional Units if the underwriters’ over-allotment option is exercised in full), each Unit consisting of one
share of common stock, par value $.01 per share (the “Common Stock”) and two warrants (the “Warrants”), each warrant entitling its holder to purchase one share of Common Stock (the “Warrant
Shares”); 
 WHEREAS, the Company has filed, with the Securities and Exchange Commission (the
“SEC”), a registration statement on Form S-1 (Registration No. 333-164575), as amended (the “Registration Statement”), for the registration, under the Securities Act of 1933, as amended (the
“Act”), of, among other securities, the Warrants and the Warrant Shares; and 
 WHEREAS, the Company desires
the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and 
 WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and
exercised, and the respective rights, limitation of rights and immunities of the Company, the Warrant Agent and the holders of the Warrants; and 
 WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as
provided herein, the legally valid and binding obligations of the Company, and to authorize the execution and delivery of this Warrant Agreement. 
 NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: 
 1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to
perform the same in accordance with the terms and conditions set forth in this Warrant Agreement. 
 2. Warrants.

 2.1 Form of Warrant. Each Warrant shall be: (a) issued in registered form only, (b) in
substantially the form of Exhibit A hereto, the provisions of which are incorporated herein, (c) signed by, or bear the facsimile signature of, the Chairman of the Board or, the Chief Executive Officer or the President, and the Treasurer,
Secretary or Assistant Secretary of the Company, and (d) shall bear a facsimile of the Company’s seal. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which
such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. 
 2.2 Effect of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this Warrant
Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof. 







 2.3 Registration. 
 2.3.1 Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”), for the
registration of the original issuance and transfers of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and
otherwise in accordance with instructions delivered to the Warrant Agent by the Company. 
 2.3.2 Registered
Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (“Registered
Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the Warrant certificate made by anyone other than the Company or the Warrant Agent), for
the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 
 2.4 Detachability of Warrants. The Common Stock and the Warrants comprising the Units will begin
to trade separately on or prior to the date that is the 90th day following the effectiveness of the Registration Statement (the “Detachment Date”), provided that in no event will separate trading of the securities comprising the Units commence until the Company issues a press
release announcing when such separate trading will begin. 
 3. Terms and Exercise of Warrants. 
 3.1 Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof,
subject to the provisions of such Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of
$             per whole share of Common Stock, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term
“Warrant Price” as used in this Warrant Agreement refers to the price per whole share at which Common Stock may be purchased at the time such Warrant is exercised. The Company, in its sole discretion, may lower the Warrant Price at
any time prior to the Expiration Date (as defined below); provided, that any such reduction shall be identical in percentage terms among all of the then outstanding Warrants. 
 3.2 Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”)
commencing on the effective date of the Registration Statement and terminating at 5:00 p.m., New York City time, on the earlier to occur of (i)             , 2015 [5 years
following the effective date], or (ii) the date fixed for redemption of the Warrants as provided in Section 6 of this Warrant Agreement (“Expiration Date”). Except with respect to the right to receive the Redemption Price
(as set forth in Section 6 hereunder), each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Warrant Agreement shall cease at the close of business
on the Expiration Date. The Company may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide notice of not less than 20 days to Registered Holders of such extension and that such
extension shall be identical in duration among all of the then outstanding Warrants. 
 3.3 Exercise of
Warrants. 
 3.3.1 Payment. Subject to the provisions of the Warrant and this Warrant Agreement, a
Warrant, when countersigned by the Company, may be exercised by the Registered Holder thereof by surrendering it at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, in the Borough of Manhattan, City and State of
New York, with the subscription form, as set forth in the Warrant, duly executed, and by paying in full, in lawful money of the United States, in cash or by certified or bank cashier’s check payable to the order of the Company, the Warrant
Price for each whole Warrant Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Warrant Shares, and the issuance of the Warrant Shares.

  

 2 








 3.3.2 Fractional Shares. Notwithstanding any provision to the
contrary contained in this Warrant Agreement, the Company shall not be required to issue any fraction of a Warrant Share in connection with the exercise of Warrants, and in any case where the Registered Holder would be entitled under the terms of
the Warrants to receive a fraction of a Warrant Share upon the exercise of such Registered Holder’s Warrants, issue or cause to be issued only the largest whole number of Warrant Shares issuable on such exercise (and such fraction of a Warrant
Share will be disregarded); provided, that if more than one Warrant certificate is presented for exercise at the same time by the same Registered Holder, the number of whole Warrant Shares which shall be issuable upon the exercise thereof shall be
computed on the basis of the aggregate number of Warrant Shares issuable on exercise of all such Warrants. 
 3.3.3 Issuance of Certificates. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price, the Company shall issue to the Registered Holder of such Warrant a certificate
or certificates representing the number of full shares of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and, if such Warrant shall not have been exercised or surrendered in
full, a new countersigned Warrant for the number of shares as to which such Warrant shall not have been exercised or surrendered. Notwithstanding the foregoing, the Company shall not be obligated to deliver any securities pursuant to the exercise of
a Warrant unless (a) a registration statement under the Act with respect to the Common Stock issuable upon exercise of such Warrants is effective and a current prospectus relating to the shares of Common Stock issuable upon exercise of the
Warrants is available for delivery to the Registered Holder of the Warrant or (b) in the opinion of counsel to the Company, the exercise of the Warrants is exempt from the registration requirements of the Act and such securities are qualified
for sale or exempt from qualification under applicable securities laws of the states or other jurisdictions in which the Registered Holder resides. Warrants may not be exercised by, or securities issued to, any Registered Holder in any state in
which such exercise or issuance would be unlawful. In the event a registration statement under the Act with respect to the Common Stock underlying the Warrants is not effective or a prospectus is not available, or because such exercise would be
unlawful with respect to a Registered Holder in any state, the Registered Holder shall not be entitled to exercise such Warrants and such Warrants may have no value and expire worthless. In no event will the Company be obligated to pay such
Registered Holder any cash consideration upon exercise or otherwise “net cash settle” the Warrant. In the event that a Registration Statement is not effective for the exercised Warrants, the purchaser of a Unit containing such Warrants,
will have paid the full purchase price for the Unit solely for the shares of Common Stock included in such Unit. 
 3.3.4 Valid Issuance. All shares of Common Stock issued upon the proper exercise or surrender of a Warrant in conformity with this Warrant Agreement shall be validly issued, fully paid and nonassessable. 
 3.3.5 Date of Issuance. Each person or entity in whose name any such certificate for shares of Common Stock is issued
shall, for all purposes, be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate, except that,
if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock
transfer books are open. 
 3.4 Warrant Solicitation and Warrant Solicitation Fee. 
 3.4.1 The Company has engaged Maxim Group LLC (“Maxim”), on a non-exclusive basis, as its agent for the
solicitation of the exercise of the Warrants. The Company, at its cost, will: (i) assist Maxim with respect to such solicitation, if requested by Maxim, and (ii) provide Maxim, and direct the Company’s transfer agent and the Warrant
Agent to deliver to Maxim, lists of the record and, to the extent known, beneficial owners of the Company’s Warrants. The Company hereby instructs the Warrant Agent to cooperate with Maxim in every respect in connection with Maxim’s
solicitation activities, including, but not limited to, providing to Maxim, at the Company’s cost, a list of record and beneficial

  

 3 








 
holders of the Warrants and circulating a prospectus or offering circular disclosing the compensation arrangements referenced in Section 3.4.2 below to holders of the Warrants at the time of
exercise of the Warrants. In addition to the conditions set forth in Section 3.4.2, Maxim shall accept payment of the warrant solicitation fee provided in Section 3.4.2 only if permitted under the rules and regulations of FINRA and only to
the extent that a holder who exercises his Warrants specifically designates, in writing, that Maxim solicited the exercise. In addition to soliciting, either orally or in writing, the exercise of Warrants by a Warrant holder, such services may also
include disseminating information, either orally or in writing, to Warrant holders about the Company or the market for the Company’s securities, or assisting in the processing of the exercise of Warrants. 
 3.4.2 In each instance in which a Warrant is exercised, the Warrant Agent shall promptly give written notice
(“Warrant Agent’s Exercise Notice”) of such exercise to the Company and Maxim. If, upon the exercise of any Warrant more than one year from the effective date of the Registration Statement: (i) the market price of the
Company’s Common Stock is greater than the Warrant Price, (ii) disclosure of compensation arrangements between the Company and Maxim with respect to the solicitation of the exercise of the Warrants was made both at the time of the Public
Offering and at the time of exercise (by delivery of a prospectus or as otherwise required by applicable law, rule or regulation), (iii) the holder of the Warrant confirms in writing that the exercise of the Warrant was solicited by Maxim,
(iv) the Warrant was not held in a discretionary account, and (v) the solicitation of the exercise of the Warrant was not in violation of Regulation M (as such rule or any successor rule may be in effect as of such time of exercise)
promulgated under the Securities Exchange Act of 1934, as amended, then the Warrant Agent, simultaneously with the distribution of the common stock underlying the Warrants so exercised in accordance with the instructions from the Company following
receipt of the proceeds to the Company received upon exercise of such Warrant(s), shall, on behalf of the Company, pay a fee of 3% of the Warrant Price to Maxim, provided that Maxim delivers to the Warrant Agent within ten (10) business
days from the date on which Maxim has received the Warrant Agent’s Exercise Notice, a certificate that the conditions set forth in the preceding clauses (iii), (iv) and (v) have been satisfied. Notwithstanding the foregoing, no fee
will be paid to Maxim or its affiliates of Warrants purchased by it or them and still held by it her them for its or their own account. Maxim and the Company may, at any time during business hours, examine the records of the Warrant Agent, including
its ledger of original Warrant certificates returned to the Warrant Agent upon exercise of Warrants. 
 3.4.3 The
provisions of this Section 3.4 may not be modified, amended or deleted without the prior written consent of Maxim. 
 4.
Adjustments. 
 4.1 Stock Dividends, Split-Ups. If, after the date hereof, and subject to the
provisions of Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock, or other similar event, then, on the effective
date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in outstanding shares of Common Stock. 
 4.2 Extraordinary Dividend. If the Company, at any time during the Exercise Period, shall pay a dividend or make a
distribution in cash, securities or other assets to the holders of Common Stock (or other shares of the Company’s capital stock into which the Warrants are exerciseable), other than (a) as described in Sections 4.1, 4.3 or 4.5,
(b) regular quarterly or other periodic dividends, (c) in connection with the conversion rights of the holders of Common Stock upon consummation of a business combination, or (d) in connection with the Company’s liquidation and
the distribution of its assets (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend,
by the amount of cash and/or the fair market value (as determined by the Company’s Board of Directors, in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. 
  

 4 








 4.3 Aggregation of Shares. If, after the date hereof, and subject to
the provisions of Section 4.7, the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date
of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common
Stock. 
 4.4 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable
upon the exercise of the Warrants is adjusted, as provided in Sections 4.1 and 4.3 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price, immediately prior to such adjustment, by a fraction, (a) the
numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (b) the denominator of which shall be the number of shares of Common Stock so purchasable
immediately thereafter. 
 4.5 Replacement of Securities upon Reorganization, etc. In case of any
reclassification or reorganization of the outstanding shares of Common Stock (other than a change covered by Sections 4.1 or 4.3 hereof or one that solely affects the par value of such shares of Common Stock), or, in the case of any merger or
consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of
Common Stock), or, in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety, in connection with which the Company is dissolved, the
Registered Holders shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and
receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a
dissolution following any such sale or transfer, that the Registered Holder would have received if such Registered Holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any reclassification also results in a change
in shares of Common Stock covered by Sections 4.1 or 4.3, then such adjustment shall be made pursuant to Sections 4.1, 4.3, 4.4 and this Section 4.5. The provisions of this Section 4.5 shall similarly apply to successive reclassifications,
reorganizations, mergers or consolidations, sales or other transfers. 
 4.6 Notices of Changes in
Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such
adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon
the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4 the Company shall give written notice to each Registered Holder, at the last address set forth for such Registered Holder in the Warrant Register, of the record date or the
effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event. 
 4.7 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price
and the same number of shares as is stated in the Warrants initially issued pursuant to this Warrant Agreement. However, the Company may, at any time, in its sole discretion, make any change in the form of Warrant that the Company may deem
appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed. 
 4.8 Notice of Certain Transactions. In the event that the Company shall (a) offer to holders of all its
Common Stock rights to subscribe for or to purchase any securities convertible into shares of Common Stock or shares of stock of any class or any other securities, rights or options, (b) issue any rights, options or warrants entitling all the
holders of Common Stock to subscribe for shares of Common

  

 5 








 
Stock, or (c) make a tender offer, redemption offer or exchange offer with respect to the Common Stock, the Company shall send to the Registered Holders a notice of such action or offer.
Such notice shall be mailed to the Registered Holders at their addresses as they appear in the Warrant Register, which shall specify the record date for the purposes of such dividend, distribution or rights, or the date such issuance or event is to
take place and the date of participation therein by the holders of Common Stock, if any such date is to be fixed, and shall briefly indicate the effect of such action on the Common Stock and on the number and kind of any other shares of stock and on
other property, if any, and the number of shares of Common Stock and other property, if any, issuable upon exercise of each Warrant and the Warrant Price after giving effect to any adjustment pursuant to this Section 4 which would be required
as a result of such action. Such notice shall be given as promptly as practicable after the Company has taken any such action. 
 5. Transfer and Exchange of Warrants. 
 5.1 Transfer of Warrants. Prior to the Detachment
Date, the Warrants may be transferred or exchanged only together with the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such Unit. Furthermore, each transfer of a
Unit on the register relating to such Units shall operate also to transfer the Warrants included in such Unit. From and after the Detachment Date, this Section 5.1 will have no further force and effect. 
 5.2 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding
Warrant into the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an
equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon the Company’s request.

 5.3 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together
with a written request for exchange or transfer, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number
of Warrants; provided, however, that, in the event a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and shall issue new Warrants in exchange therefor until the Warrant Agent has received
an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. 
 5.4 Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate for a fraction of a
warrant. 
 5.5 Service Charges. No service charge shall be made for any exchange or registration of
transfer of Warrants. 
 5.6 Warrant Execution and Countersignature. The Warrant Agent is hereby
authorized to countersign and to deliver, in accordance with the terms of this Warrant Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, will
supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose. 
 6. Redemption.

 6.1 Redemption. Subject to the second sentence of this Section 6.1, all (and not less than all) of
the outstanding Warrants may be redeemed, at the option of the Company, at any time after they become exercisable and prior to their expiration, at the office of the Warrant Agent, upon the notice referred to in Section 6.2, at the price of
$.01 per Warrant (“Redemption Price”); provided that the last sales

  

 6 








 
price of the Common Stock has been equal to or greater than $[        ] per share (subject to adjustment for splits, dividends, recapitalizations and other
similar events), on each of twenty (20) trading days within any thirty (30) trading day period ending on the third business day prior to the date on which notice of redemption is given. Notwithstanding the foregoing, a registration
statement under the Act with respect to the shares of Common Stock issuable upon exercise must be effective and a current prospectus must be available for use by the Registered Holders thereof in order for the Company to exercise its redemption
rights pursuant to this Section 6. 
 6.2 Date Fixed for, and Notice of, Redemption. In the event the
Company shall elect to redeem all of the Warrants, the Company shall fix a date for the redemption. Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than 30 days prior to the date fixed for
redemption to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the Warrant Register. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether
or not the Registered Holder received such notice. 
 6.3 Exercise After Notice of Redemption. The
Warrants may be exercised in accordance with Section 3 of this Warrant Agreement at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the time and date fixed for
redemption. On and after the redemption date, the Registered Holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price. 
 6.4 No Other Rights to Cash Payment. Except for a redemption in accordance with this Section 6, no Registered
Holder of any Warrant shall be entitled to any cash payment whatsoever from the Company in connection with the ownership, exercise or surrender of any Warrant under this Warrant Agreement, regardless of whether a registration statement under the Act
with respect to the shares of Common Stock issuable upon exercise is effective and a current prospectus is available for use by the Registered Holders thereof. 
 7. Other Provisions Relating to Rights of Registered Holders of Warrants. 
 7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive
dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter. 
 7.2 Lost, Stolen Mutilated or Destroyed Warrants. If any Warrant is lost, stolen, mutilated or destroyed, the Company
and the Warrant Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor and
date as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time
enforceable by anyone. 
 7.3 Reservation of Common Stock. The Company shall at all times reserve and keep
available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement. 
 7.4 Registration of Common Stock. The Company agrees that prior to the commencement of the Exercise Period, it shall
file with the SEC a post-effective amendment to the Registration Statement, or a new registration statement, for the registration, under the Act, of the Common Stock issuable upon exercise of the Warrants, and it shall take such action as is
necessary to qualify for sale, in those states in which the Warrants were initially offered by the Company, the Common Stock issuable upon exercise of the Warrants. In either case, the Company will use its best efforts to cause the same to become
effective on or prior to the commencement of the Exercise Period and to use its best efforts

  

 7 








 
to maintain the effectiveness of such registration statement until the expiration of the Warrants in accordance with the provisions of this Warrant Agreement; provided, however, that the Company
shall not be obligated to deliver Common Stock and shall not have penalties for failure to deliver Common Stock if a registration statement is not effective or a current prospectus is not on file with the SEC at the time of exercise by the
Registered Holder. In addition, the Company agrees to use its reasonable efforts to register such securities under the blue sky laws of the states of residence of the exercising Registered Holders to the extent an exemption under the Act is not
available for the exercise of the Warrants. In no event will the Registered Holder of a Warrant be entitled to receive a net-cash settlement or shares of Common Stock or other consideration as of result of the Company’s non-compliance with this
Section 7.4. The provisions of this Section 7.4 may not be modified, amended or deleted without the prior written consent of Maxim, the representative of the underwriters (the “Underwriters”). 
 8. Concerning the Warrant Agent and Other Matters. 
 8.1 Payment of Taxes. The Company will, from time to time, promptly pay all taxes and charges that may be imposed upon
the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares. 

8.2 Resignation, Consolidation, or Merger of Warrant Agent. 
 8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may
resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or
otherwise, the Company shall appoint, in writing, a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such resignation or
incapacity by the Warrant Agent or by the Registered Holder of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the Registered Holder of any Warrant may apply to the Supreme Court of the
State of New York for the County of New York for the appointment of a successor Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State
of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and be authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state
authorities. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent
hereunder, without any further act or deed; but, if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant
Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and, upon request of any successor Warrant Agent, the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully
and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties and obligations. 
 8.2.2 Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the transfer agent for
the Common Stock not later than the effective date of any such appointment. 
 8.2.3 Merger or Consolidation
of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor
Warrant Agent under this Warrant Agreement without any further act on the part of the Company or the Warrant Agent.

 8.3 Fees and Expenses of Warrant Agent. 
 8.3.1 Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as Warrant
Agent hereunder as set forth on Exhibit B hereto and will reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder. 
 8.3.2 Further Assurances. The Company agrees to perform, execute, acknowledge and deliver, or cause to be performed,
executed, acknowledged and delivered, all such further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Warrant Agreement. 
 8.4 Liability of Warrant Agent. 
 8.4.1 Reliance on Company Statement. Whenever, in the performance of its duties under this Warrant Agreement, the
Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein
specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant
Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Warrant Agreement. 
 8.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and hold it harmless
against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Warrant Agreement, except as a result of the Warrant Agent’s negligence, willful
misconduct or bad faith. 
 8.4.3 Exclusions. The Warrant Agent shall have no responsibility with respect
