 VIRAGEN, INC. 
 CUSIP                      
 WARRANT 
 THIS CERTIFIES THAT, for value received 
 is the registered holder of a Warrant or Warrants expiring
                    , 2011 (the “Warrant”) to purchase one fully paid and non-assessable share of Common Stock, par value $.01 per share
(“Shares”), of Viragen, Inc., a Delaware corporation (the “Company”), for each Warrant evidenced by this Warrant Certificate. The Warrant entitles the holder thereof to purchase from the Company, commencing on the date of
separation of the Warrant from the Unit as described in Section 2.4 of the Warrant Agreement, such number of Shares of the Company at the price of
$                     per share (subject to adjustment), upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or
agency of the Warrant Agent, Mellon Investor Services LLC (such payment to be made in cash or by good certified check or good bank draft made payable to the Company), but only subject to the conditions set forth herein and in the Warrant Agreement
between the Company and Mellon Investor Services LLC. The Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant and shall have no obligation to settle a Warrant exercise unless a registration statement under
the Securities Act of 1933, as amended, (the “Act”) with respect to the Common Stock is effective, subject to the Company satisfying its obligations under Section 7.4 of the Warrant Agreement to use its best efforts. In the event that
a registration statement with respect to the Common Stock underlying a Warrant is not effective under the Act, the holder of such Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless. In no
event will the Company be required to net cash settle the warrant exercise. The Warrant Agreement provides that upon the occurrence of certain events the Warrant Price and the number of Warrant Shares purchasable hereunder, set forth on the face
hereof, may, subject to certain conditions, be adjusted. The term Warrant Price as used in this Warrant Certificate refers to the price per Share at which Shares may be purchased at the time the Warrant is exercised. 
 No fraction of a Share will be issued upon any exercise of a Warrant. If the holder of a Warrant would be entitled to receive a fraction of a Share upon any exercise of
a Warrant, the Company shall, upon such exercise, round up on the basis of the aggregate number of shares purchasable to the nearest whole number the number of the shares of Common Stock to be issued to the Warrant holder. 
 Upon any exercise of the Warrant for less than the total number of full Shares provided for herein, there shall be issued to the registered holder hereof or the
registered holder’s assignee a new Warrant Certificate covering the number of Shares for which the Warrant has not been exercised. 

 Warrant Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder hereof in
person or by attorney duly authorized in writing, may be exchanged in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of
like tenor and evidencing in the aggregate a like number of Warrants. 
 Upon due presentment for registration of transfer of the Warrant Certificate at the
office or agency of the Warrant Agent, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee in exchange for this Warrant Certificate, subject to
the limitations provided in the Warrant Agreement, without charge except for any applicable tax or other governmental charge. 
 The Company and the Warrant
Agent may deem and treat the registered holder as the absolute owner of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the
registered holder, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 
 This Warrant
does not entitle the registered holder to any of the rights of a stockholder of the Company. 
 The Company reserves the right to call the Warrant, in whole
or in part, at any time prior to its exercise, and with the consent of Dawson James Securities, Inc. with a notice of call in writing to the holders of record of the Warrant, giving 30 days’ notice of such call at any time after six months from
the date the Warrant becomes exercisable if the last sale price of the Shares has been at least $                     per share (subject to
adjustment) on any 20 trading days within any 30 trading day period ending on the third business day prior to the date on which notice of such call is given. The call price of the Warrants is to be $0.001 per Warrant. Any Warrant either not
exercised or tendered back to the Company by the end of the date specified in the notice of call shall be canceled on the books of the Company and have no further value except for the
$                     call price.

 Exhibit 4.10 
 WARRANT AGREEMENT 
 Agreement made as of
                    , 2006 between Viragen, Inc., a Delaware corporation, with offices at 865 Southwest 78th Avenue, Suite 100, Plantation, Florida 33324 (“Company”), and Mellon Investor Services LLC, a New Jersey limited liability company, with
offices at One Mellon Center, 500 Grant Street, Suite 2122, Pittsburg, Pennsylvania 15258 (“Warrant Agent”). 
 WHEREAS, the
Company is engaged in a public offering (“Public Offering”) of Units (“Units”) and, in connection therewith, has determined to issue and deliver, on the detachment date described in Section 2.4 below, and from time-to-time
thereafter, up to (i)                      Warrants (“Public Warrants”) to the public investors, and
(ii)                      Warrants to Dawson James Securities, Inc. (“Dawson James” or the “Underwriter”) or its
designees (“Underwriter’s Warrants” and, together with the Public Warrants, the “Warrants”) as part of a Unit Purchase Option, dated as of
                    , 2006 (the “Purchase Option”), each Public Warrant evidencing the right of the holder thereof to purchase one
share of the Company’s common stock, par value $.01 per share (“Common Stock”), for $                    , subject to
adjustment as described herein and each Underwriter’s Warrant evidencing the right of the holder thereof to purchase one share of Common Stock for
$                    , subject to adjustment described herein; and 
 WHEREAS, the Company has filed with the Securities and Exchange Commission a Registration Statement, No. 333-136144 on Form S-1 (“Registration
Statement”), for the registration, under the Securities Act of 1933, as amended (“Act”) of, among other securities, the Units, the Warrants and the Common Stock issuable upon exercise of the Warrants; 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 valid, binding and legal 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 Public Warrant shall be issued in
registered form only, shall be in substantially the form of Exhibit A hereto, and which shall include the subscription form to be printed 

  

 1 

 
on the reverse thereof, with such changes, marks of identification or designation and legends, summaries or endorsements printed thereon as the Company may
deem appropriate but which do not change the rights, duties or obligations of the Warrant Agent hereunder, and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto. The provisions of the Warrant are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairman of the Board or President and Treasurer, Secretary or Assistant Secretary of the Company
(“Authorized Officers”) and 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 force and effect as if he or she had not ceased to be such at the date of issuance and delivery by the Company. The Underwriter’s Warrant shall be in the form of Exhibit B
thereto. 
 2.2 Effect of Countersignature. The Warrants will then be countersigned by the Warrant Agent, unless and
until countersigned by the Warrant Agent pursuant to this Warrant Agreement, a Warrant shall be invalid and of no effect for any purpose and may not be exercised by the holder thereof. Such signature by the Warrant Agent upon any Warrant executed by
the Company shall be conclusive evidence that such Warrant has been duly issued under the terms of this Warrant Agreement. 
 2.3 Registration. 
 2.3.1 Warrant Register. The Warrant Agent is hereby authorized and instructed to
keep or cause to be kept, at the office of the Warrant Agent designated for such purpose, the books (“Warrant Register”) for the registration of original issuance and the registration of transfer 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. Neither the
Company nor the Warrant Agent will be liable or responsible for any registration or transfer of any Warrants that are registered or are to be registered in the name of a fiduciary or the nominee of a fiduciary. 
 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 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 securities comprising the Units will not be separately
transferable prior to                     , 2007, subject to earlier separation in the discretion of Dawson James; provided, however, in no event
will Dawson James allow separate trading until (i) the preparation of an audited balance sheet of the Company reflecting receipt by the Company of the proceeds of the offering of the Units and the filing of such audited balance sheet with the
Securities and Exchange Commission on a Form 8-K or similar form by the Company which includes such balance sheet; (ii) the Company files a Form 8-K and issues a press release announcing when such separate trading will begin; and (iii) the
business day following the earliest to occur of the expiration of the over-allotment option or the exercise of the over-allotment option in full. 
 2.5 Warrants and Underwriter’s Warrants. The Underwriter’s Warrants shall have the same terms and be in the same form as the Public Warrants except with respect to the Warrant Price as set forth below
in Section 3.1. 
  

 2 

 2.6 Initial Issuance of Public Warrants and Underwriter’s Warrants.

 2.6.1 Public Warrants. Prior to the detachment date described above in Section 2.4, there will be no Public
Warrants issued and outstanding. On and after the detachment date, each holder of a Unit shall thereafter be entitled to receive, and the Warrant Agent shall issue, through the facilities of The Depository Trust Company or in certificated form (as
and when Unit certificates are presented to the Transfer Agent for transfer, or exchange for shares of Common Stock and Public Warrants), that number of Public Warrants as were included in the holder’s Units immediately prior to the detachment
date. 
 2.6.2 Underwriter’s Warrants. The Underwriter may exercise Purchase Options from time to time following
the date on which the Purchase Options become exercisable, and, in connection therewith, the Company may instruct the Warrant Agent to issue Warrants to the Underwriter upon such exercise. The Warrant Agent shall issue Underwriter’s Warrants,
in certificated form, up to the maximum number of Underwriter’s Warrants specified in the Preamble to this Agreement, in accordance with the written instructions of the Company. 
 2.6.3 Delivery of Warrants; Effect on Agreement. From and after the date Warrants are issued in accordance with Sections 2.6.1 and
2.6.2, above, (a) the Public Warrants, but not the Underwriter’s Warrants, may be delivered through the facilities of The Depository Trust Company or in certificated form, and (b) such Warrants shall be governed by the terms and
conditions of this Agreement. 
 3. Terms and Exercise of Warrants. 
 3.1 Warrant Price. Each Public 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, subject to the adjustments provided in Section 4 hereof and in the last sentence of this
Section 3.1. The Underwriter’s 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, 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 share at which Common Stock may be purchased at the time a Warrant is exercised.
The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined in Section 3.2 below) with prompt written notice to the Warrant Agent; provided, that any such reduction shall be identical in
percentage terms among all of the Warrants and such lowered Warrant Price must remain in effect for a minimum of ten (10) business days. 
 3.2 Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) which commences on the date of the separation of the Unit as described in Section 2.4, and will
expire unless exercised before 5:00 p.m., New York City time, on the earlier to occur of (i)                     , 2011 or (ii) the
date fixed for redemption of the Warrants as provided in Section 6 of this Agreement (the “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 Agreement shall cease at the close of business on the Expiration Date. The Company in its sole discretion may
extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide prompt written notice of not less than 20 days to the Warrant Agent and the registered holders of the Warrants of such extension;
provided, further, that any such extension shall be identical in duration among all of the Warrants. 
  

 3 

 3.3 Exercise of Warrants. 
 3.3.1 Payment. Subject to the provisions of the Warrant and this Warrant Agreement, including Section 3.3.2, a Warrant, when
countersigned by the Warrant Agent, 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, good certified check or good bank draft payable to the order of the Company (or as otherwise agreed
to by the Company), the Warrant Price for each full share of Common Stock 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 Common Stock, and
the issuance of the Common Stock. 
 3.3.2 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 for 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 in full, a new countersigned Warrant for the number of shares as to which such Warrant shall not have been exercised.
Notwithstanding the foregoing, the Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant and shall have no obligation to settle the Warrant exercise unless (i) a registration statement under the Act with
respect to the Common Stock is effective, subject to the Company satisfying its obligations under Section 7.5 to use its best efforts, or (ii) 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 holders reside. In the event that a
registration statement with respect to the Common Stock underlying a Public Warrant or Underwriter’s Warrant is not effective under the Act, the holder of such Public Warrant or Underwriter’s Warrant shall not be entitled to exercise such
Warrant and such Warrant may have no value and expire worthless. In no event will the Company be required to net cash settle the warrant exercise. Public Warrants and Underwriter’s Warrants may not be exercised by, or securities issued to, any
registered holder in any state in which such exercise would be unlawful. Warrants may not be exercised by, or securities issued to, any registered holder in any state in which such exercise would be unlawful. The Warrant Agent shall have no duty or
liability with regard to the enforcement of the preceding sentence, nor shall it be deemed to knowledge of the laws of any jurisdiction with regard to such exercise, unless and until it has been advised thereof in writing by the Company and
instructed as to what action it should take. 
 3.3.3 Valid Issuance. All shares of Common Stock issued upon the proper
exercise of a Warrant in conformity with this Warrant Agreement shall be validly issued, fully paid and nonassessable. 
 3.3.4 Date of Issuance. Each person 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. 
 3.3.5 Warrant Solicitation and Warrant Solicitation Fee. 
 (a) The Company has
engaged Dawson James, 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 Dawson 

  

 4 

 
James with respect to such solicitation, if requested by Dawson James, and (ii) at Dawson James’ request, provide Dawson James, and direct, through
written instructions, the Company’s transfer and warrant agent to provide Dawson James, lists of the record, and to the extent known, beneficial owners of the Warrants. The Company hereby instructs the Warrant Agent to cooperate with Dawson
James in every reasonable respect in connection with Dawson James’ solicitation activities, including, but not limited to, providing to Dawson James, at the Company’s cost and upon written instruction to the Warrant Agent, a list of record
and beneficial holders of the Warrants and circulating a prospectus disclosing the compensation arrangements referenced in Section 3.3.5(b) below to holders of the Warrants at the time of exercise of the Warrants. In addition to the conditions
set forth in Section 3.3.5(b), Dawson James shall accept payment of the warrant solicitation fee provided in Section 3.3.5(b) only if permitted under the rules and regulations of the NASD and only to the extent that the investor who
exercises his, her or its Warrants specifically designates, in writing, that Dawson James solicited his, her or its exercise. In addition to soliciting, either orally or in writing, the exercise of Warrants by a Warrantholder, such services may also
include disseminating information, either orally or in writing, to Warrantholders about the Company or the market for the Company’s securities, or assisting in the processing of the exercise of Warrants. 
 (b) In each instance in which a Warrant is exercised, the Warrant Agent shall give written notice of such exercise within a reasonable
time period to the Company and Dawson James (“Warrant Agent’s Exercise Notice”). 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 was made both at the time of the Public Offering and at the time of exercise (by delivery of the 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 Dawson James, (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 proceeds to the Company received upon exercise of the Warrant(s) so exercised, shall, on behalf of the Company, pay from the proceeds received upon exercise of the Warrant(s), a fee of 5% of the Warrant
Price to Dawson James, provided that Dawson James delivers to the Warrant Agent within ten (10) business days from the date on which Dawson James 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 and the Company provides written notice as to (i) and (ii) authorizing such payment. Notwithstanding the foregoing, no fee will be paid to Dawson James with respect
to the exercise by the Underwriter or its affiliates of Warrants purchased by it or them upon exercise of the Underwriter’s Warrants and still held by the Underwriter or them for its or their own account. Dawson James 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. 
 (c) The provisions of this Section 3.3.5. may not be modified, amended or deleted without the prior written consent of Dawson James.

 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. 
  

 5 

 4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions
of Section 4.6, 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.

 4.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of
the Warrants is adjusted, as provided in Section 4.1 and 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) 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 (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately
thereafter. 
 4.4 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 Section 4.1 or 4.2 hereof or 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 entity (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 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 Warrant 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
Warrant holder would have received if such Warrant 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 Section 4.1 or 4.2,
then such adjustment shall be made pursuant to Sections 4.1, 4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or
other transfers. 
 4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number or kind
of shares issuable upon exercise of a Warrant, the Company shall promptly 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 a brief statement of the facts requiring the adjustments and the method of calculation upon which the adjustments are based. The notice shall be
conclusive evidence of the correctness of the adjustments and the Warrant Agent may rely on it for all purposes. The Warrant Agent will not be deemed to have any notice of any said adjustment prior to receiving such notice. Notwithstanding anything
to the contrary contained herein, the Warrant Agent shall have no duty or obligation to (i) determine if any adjustments are warranted hereunder or (ii) investigate or confirm whether the information contained in such notice complies with
the terms of this Agreement or any other document, or is accurate and correct. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, then, in any such event, the Company shall give written notice to each Warrant holder, at the
last address set forth for such 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. 
  

 6 

 4.6 No Fractional Shares. Notwithstanding any provision contained in this Warrant
Agreement to the contrary, the Company shall not issue fractional shares upon exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant,
to receive a fractional interest in a share, the Company shall, upon such exercise, round up on the basis of the aggregate number of shares purchasable to the nearest whole number the number of the shares of Common Stock to be issued to the Warrant
holder. 
 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, written notice of which shall be promptly delivered to the Warrant Agent, 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. 
 5.
Transfer and Exchange of Warrants. 
 5.1 Registration of Transfer. The Warrant Agent shall register the
transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate written 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 request. 
 5.2 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 that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and 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. 
 5.3 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. 
 5.4 Service Charges. No service charge
to a registered holder shall be made for any exchange or such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 5.5 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 Section 6.4 hereof, the Warrants may be redeemed, at the option of the Company, in whole or in
part, at any time commencing six months after they become exercisable 

  

 7 

 
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 $.001 per Warrant
(“Redemption Price”), provided that the last sales price of the Common Stock has been at least $                     per share, on
each of twenty (20) trading days within any thirty (30) trading day period ending on the third business day prior to but not including the date on which notice of redemption is given and provided that the Warrants and shares of common
stock underlying the Warrants are covered by a registration statement that is effective under the Act. Because redemption is at the option of the Company and because such redemption is subject to conditions, any or all of the Warrants may expire
unredeemed. The provisions of this Section 6.1 may not be modified, amended or deleted without the prior written consent of Dawson James. In determining whether to grant consent to any redemption, Dawson James will assess the relative strengths
of the securities markets and similar companies, in general, and the trading pattern of, and demand for the Company’s securities in particular. 
 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 Warrant Agent and the registered holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration
books. 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, for cash 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 record holder of the Warrants shall have no further rights except to receive, upon surrender of
the Warrants, the Redemption Price. 
 6.4 Outstanding Warrants Only. The Company understands that the redemption
rights provided for by this Section 6 apply only to outstanding Warrants. To the extent a person holds rights to purchase Warrants, such purchase rights shall not be extinguished by redemption. However, once such purchase rights are exercised,
the Company may redeem the Warrants issued upon such exercise provided that the criteria for redemption is met, including the opportunity of the Warrant holder to exercise prior to redemption pursuant to Section 6.3. The provisions of this
Section 6.4 may not be modified, amended or deleted without the prior written consent of Dawson James. 
 7. Other Provisions
Relating to Rights of Holders of Warrants. 
 7.1 No Rights as Stockholder. Nothing contained in this Agreement or
in the Warrant will be construed as conferring upon the registered holder thereof or his transferees 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. Upon (a) receipt be the Company and the Warrant Agent of (i) evidence
satisfactory to the Company and the Warrant Agent of the loss, theft, mutilation, or destruction of a Warrant and (ii) security or indemnity as may be satisfactory to the Company or the Warrant Agent, and (b) surrender to the Warrant Agent
and cancellation of the Warrant if mutilated, the Company will prepare, execute and deliver a new Warrant of like denomination, tenor, and dated as of such cancellation date to the Warrant Agent and the Warrant Agent will countersign and deliver the
new Warrant to the holder in lieu of 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. 
  

 8 

 7.3 Cancellation and Destruction of Warrants. All Warrants surrendered for the
purpose of exercise, transfer, split up, combination or exchange will, if surrendered to the Company, be delivered to the Warrant Agent for cancellation or in canceled form, or, if surrendered to the Warrant Agent, will be canceled by the Warrant
Agent, and no Warrants will be issued in lieu thereof except as expressly permitted by this Agreement. The Company will deliver to the Warrant Agent for cancellation and retirement, and the Warrant Agent will so cancel and retire, any other Warrant
purchased or acquired by the Company otherwise than upon the exercise thereof. The Warrant Agent will destroy such canceled and retired Warrants and notify the Company of the destruction of such Warrants. 
 7.4 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. 
 7.5 Registration of Common Stock. The Company agrees that prior to the commencement of the Exercise Period, it shall prepare and file with the Securities and Exchange Commission a post-effective amendment to
the Registration Statement, or a new registration statement, for the registration, under the Act, of, and shall use its best efforts to take such action as is necessary to qualify for sale, in those states in which the Warrants were initially
offered by the Company and 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 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 securities and shall not have
penalties for failure to deliver securities, if a registration statement is not effective at the time of exercise by the holder. The provisions of this Section 7.5 may not be modified, amended or deleted without the prior written consent of
Dawson James. 
 8. Concerning the Warrant Agent and Other Matters. 
 8.1.1 Compensation. The Company will pay to the Warrant Agent reasonable compensation for all services rendered by it hereunder
and, from time to time, on demand of the Warrant Agent, its reasonable expenses and reasonable counsel fees and expenses and other disbursements incurred in the preparation, delivery, administration, execution and amendment of this Agreement and the
exercise and performance of its duties hereunder. The Company will indemnify the Warrant Agent for, and hold it harmless against, any loss, liability, suit, action, proceeding, damage, judgment, claim, settlement, cost or expense, incurred without
gross negligence, bad faith or willful misconduct (as each is determined by a final non-appealable order of a court of competent jurisdiction) on the part of the Warrant Agent, for any action taken, suffered or omitted by the Warrant Agent in
connection with the acceptance and administration of this Agreement (collectively, “Losses”), including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, except in each case for
Losses that arise out of or in connection with any gross negligence, bad faith or willful misconduct by the Warrant Agent or its agents or representatives. The Warrant Agent shall not be obligated to expend or risk its own funds or to take any
action which it believes would expose it to expense or liability or to a risk of incurring expense or liability, unless it has been furnished with assurances of repayment or indemnity reasonably satisfactory to it. 
 8.1.2 Liability. The Warrant Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct (as
each is determined by a final non-appealable order of a court of competent jurisdiction). Notwithstanding anything in this Agreement to the contrary, in no event shall the Warrant Agent be liable for special, punitive, incidental, indirect or
consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Warrant Agent has been advised of the likelihood of such loss or damage and regardless of the form of the action. Any liability of 

  

 9 

 
the Warrant Agent under this Agreement shall be limited to the amount of fees paid by the Company to the Warrant Agent. 
 8.1.3 Reliance on Warrants. The Warrant Agent will be protected and will incur no liability for or in respect of any action taken,
suffered or omitted by it in connection with its administration of this Agreement in reliance upon any Warrant or certificate evidencing Common Stock or other securities of the Company, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate, statement, other paper or document reasonably believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged by the proper person or
persons. The provisions of and rights and obligations contained in this Section 8.1.3 shall survive the termination of this Agreement and/or the Warrants and the resignation, replacement or removal of the Warrant Agent. 
 8.2 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. Notwithstanding the
foregoing, neither the Company nor the Warrant Agent will be required to pay any tax or other governmental charge that may be payable in connection with any split up, further transfer, combination, exercise or exchange of Warrants in any name other
than that of the holder thereof. The Warrant Agent shall have no duty or obligation to take any action under any Section of this Agreement which requires the payment by a holder of applicable taxes or governmental charges unless and until the
Warrant Agent is satisfied that all such taxes and/or charges are paid. 
 8.3 Resignation, Consolidation, or Merger of
Warrant Agent. 
 8.3.1 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 thirty (30) 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 holder of the Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the 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 at the Company’s cost. Any successor warrant agent, whether appointed by the Company or by such court, shall be a corporation or other entity organized and existing
under the laws of the State of New York, in good standing and having an office in the Borough of Manhattan, City and State of New York, and subject to supervision or examination by federal or state authority. 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. 
 8.3.2 Notice of Successor Warrant
Agent. In the event a successor Warrant Agent shall be appointed, the Company shall file notice thereof in writing with the predecessor Warrant Agent and 

  

 10 

 
each transfer agent for the Common Stock not later than the effective date of any such appointment. Failure to give any notice provided for in this
Section 8.3.2, however, or any defect therein, will not affect the legality or validity of the resignation or removal of the Warrant Agent or the appointment of the successor warrant agent, as the case may be. 
 8.3.3 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. 
 8.4 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. 
 8.5 Duties and Obligations of Warrant Agent. 
 8.5.1 The Warrant Agent undertakes only the duties and obligations expressly imposed by this Agreement (and no implied duties) upon the
following terms and conditions, by all of which the Company and the holders, by their acceptance of Warrants, will be bound. 
 8.5.2 The Warrant Agent may consult with legal counsel (who may be legal counsel for the Company or an employee of the Warrant Agent), and the advice or opinion of such counsel will be full and complete authorization and protection to the
Warrant Agent as to any action taken, suffered or omitted by it in accordance with such advice or opinion. 
 8.5.3 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 President 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 by it pursuant to the provisions of this Warrant Agreement. 
 8.5.4 The Warrant Agent shall not be liable and shall be fully protected in acting upon any written notice, instruction, direction, request or other communication which the Warrant Agent believes to be genuine, and
shall have no duty to inquire into or investigate the validity, accuracy or content thereof. The Warrant Agent shall not take any instructions or directions except those given in accordance with this Warrant Agreement. 
 8.5.5 The Warrant Agent will not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in
the Warrants or be required to verify same, and all such statements and recitals are and will be deemed to have been made by the Company only. 
 8.5.6 The Warrant Agent shall have no responsibility or liability with respect to the validity of this Warrant Agreement or with respect to the validity or execution of any Warrant (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Warrant Agreement or in any Warrant; nor shall it be responsible to make any adjustments required under the provisions of
Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any
representation or warranty as to the 

  

 11 

 
authorization or reservation of any shares of Common Stock to be issued pursuant to this Warrant Agreement or any Warrant or as to whether any shares of
Common Stock will when issued be validly authorized and issued, fully paid and nonassessable. 
 8.5.7 The Company will
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 by the Warrant Agent of the provisions of this Agreement. 
 8.5.8 The Warrant Agent and any member, stockholder,
director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend
money to the Company or any affiliate thereof or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein will preclude the Warrant Agent from acting in any other capacity for the Company or for any
other legal entity. 
 8.5.9 The Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or
perform any duty hereunder either itself or by or through its attorneys, accountants, agents or other experts, and the Warrant Agent will not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or
for any loss to the Company or the holders of Warrants resulting from any such act, default, neglect or misconduct, absent gross negligence or bad faith (as each is determined by a final non-appealable order of a court of competent jurisdiction) in
the selection and continued employment thereof. 
 8.5.10 The Warrant Agent will not be under any duty or responsibility to
insure compliance with any applicable federal or state securities laws in connection with the issuance, transfer or exchange of Warrants. 
 8.5.11 Without limiting the foregoing, unless otherwise expressly provided in this Agreement, the Warrant Agent shall not be subject to, nor be required to comply with, or determine if any person or entity has
complied with, the Warrant or any other agreement between or among the parties hereto, even though reference thereto may be made in this Warrant Agreement, or to comply with any notice, instruction, direction, request or other communication, paper
or document other than as expressly set forth in this Warrant Agreement. 
 8.5.12 The Warrant Agent shall not incur any
liability for not performing any act, duty, obligation or responsibility by reason of any occurrence beyond the control of the Warrant Agent (including without limitation any act or provision of any present or future law or regulation or
governmental authority, any act of God, war, civil disorder or failure of any means of communication). 
 8.5.13 In the event
the Warrant Agent believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Warrant Agent hereunder, the Warrant Agent may, in its sole
discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to the Company or any holder or other person or entity for refraining from taking such action, unless the Warrant Agent receives written
instructions signed by the Company which eliminates such ambiguity or uncertainty to the satisfaction of Warrant Agent 
 8.5.14 The rights and obligations contained in this Section shall survive the termination of this Warrant Agreement and the resignation, replacement or removal of the Warrant Agent. 
  

 12 

 8.6 Acceptance of Agency. The Warrant Agent hereby accepts the agency established
by this Warrant Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the
Company, all moneys received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of Warrants. 
 9.
Representations and Warranties of the Company. The Company hereby represents and warrants to the Warrant Agent that:

for the purposes of Sections 3.3.5, 6.1, 6.4, 7.5 and 10.2 hereof, Dawson James, any right, remedy, or claim under or by reason of this Warrant Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. Dawson James shall be
deemed to be a third-party beneficiary of this Warrant Agreement with respect to Sections 3.3.5, 6.1, 6.4, 7.5 and 10.2 hereof. All covenants, conditions, stipulations, promises, and agreements contained in this Warrant Agreement shall be for the
