 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”; together with
                    , the “Underwriters”) or its designees (“Underwriters’ 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 Underwriters’ 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-                     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, the provisions of which 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 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 effect as if he or she had not ceased to be such at the date of issuance. Each
Underwriter’ Warrant shall be in the form of Exhibit B thereto. 
 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. Such signature by the Warrant Agent upon any Warrant executed by the Company
shall be conclusive evidence that such Warrant certificate has been duly issued under the terms of this Warrant Agreement. 
 2.3 Registration. 
 2.3.1 Warrant Register. The Warrant Agent shall maintain 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. 
 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 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 Underwriters’ Warrants. The Underwriters’ 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.

 2.6 Initial Issuance of Public Warrants and Underwriters’ 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 Underwriters’ Warrants. The Underwriters 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 Underwriters upon such exercise. The Warrant Agent shall issue Underwriters’ Warrants, in
certificated form, up to the maximum number of Underwriters’ 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 Underwriters’ Warrants, may 

  

 2 








 
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. Each Underwriters’ 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); provided, that any such reduction shall be identical in percentage terms among all of the Warrants. 
 3.2 Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) which commences on
                    , 2007, 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 written notice to registered holders of the Warrants of such extension of not less than 20 days; provided, further, that any such extension shall be identical in duration among all of the Warrants. 
 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 7.4 to use its best efforts, or (ii) in the opinion of counsel to the Company, the exercise of the Warrants is exempt 

  

 3 








 
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 Underwriters’ Warrant is not effective under the Act, the holder of
such Public Warrant or Underwriters’ 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 Underwriters’ 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. 
 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 James with respect to such solicitation, if requested by Dawson James, and (ii) at
Dawson James’ request, provide Dawson James, and direct 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 respect in connection with Dawson James’ solicitation activities, including, but not limited to, providing to Dawson James, at the Company’s cost, 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 promptly give written notice of such exercise 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 

  

 4 








 
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. Notwithstanding the foregoing, no fee will be paid to Dawson James with respect to the exercise by the Underwriters or their affiliates of Warrants purchased by it or them upon exercise of the Underwriters’
Warrants and still held by the Underwriters 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. 
 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
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 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. 
  

 5 








 4.5 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, 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. 
 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 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, 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 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 shall be made for any exchange or registration of transfer of Warrants. 
 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 








 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 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 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 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. 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 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 








 7.4 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 6.4 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 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 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 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 authorized under such laws to exercise corporate trust powers 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. 
 8.2.2 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 

  

 8 








 
which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Warrant Agreement without any further act. 
 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 such Warrant Agent
hereunder 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
