 The Company has filed with the Securities and Exchange Commission a Registration Statement, No. 333-122303 on Form S-1 (“Registration
Statement”) for the registration, under the Securities Act of 1933, as amended (“Act”) of, among other securities, the Warrants and the Common Stock issuable upon exercise of the Warrants; and 
 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,

 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 
 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 Agreement. 







 NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein, and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, 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 Agreement. 
 2. Warrants. 
 2.1. Form of Warrant. Each Warrant shall be issued in registered form only, shall be in substantially the respective forms of Exhibits A and B 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.

 2.2. Effect of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this 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 (“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 until 90 days after the date hereof unless Brenner informs the Company of its decision to allow earlier separate trading, but in no event will Brenner allow separate trading of the
securities comprising the Units until the Company files a Current Report on Form 8-K which includes an audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Public Offering including the proceeds received by the
Company from the exercise of the Underwriter’s over-allotment option, if the over-allotment option is exercised prior to the filing of the Form 8-K.

 2.5 Warrant Attributes. The Insiders’ Warrants, the Public Warrants and the
Representative’s Warrants shall have the same terms except with respect to the Warrant Price and Exercise Period as set forth below in Sections 3.1 and 3.2. 
 3. Terms and Exercise of Warrants 
 3.1. Warrant Price. Each Insiders’ Warrant and Public Warrant shall, when
countersigned by the Warrant Agent, entitle the registered holder thereof, subject to the provisions of such Insiders’ Warrant and Public Warrant, as applicable, and of this Warrant Agreement, to purchase from the Company the number of shares
of Common Stock stated therein, at the price of $5.00 per whole share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. Each Representative’s Warrant shall, when countersigned by
the Warrant Agent, entitle the registered holder thereof, subject to the provisions of such Representative’s Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price
of $5.50 per whole share, subject to the adjustments provided in Section 4 hereof. 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. 
 3.2. Duration of
Warrants. 
 (a) A Class W or Class Z Warrant may be exercised only during the period (“Exercise Period”) commencing on the
later of (i) the consummation by the Company of a merger, capital stock exchange, asset acquisition or other similar business combination (“Business Combination”) (as described more fully in the Company’s Registration Statement)
or (ii) April 11, 2006. Each Insiders’ Warrant and Public Warrant shall terminate at 5:00 p.m., New York City time, on the earlier to occur of (i) April 10, 2010 if a Class W Warrant or April 10, 2012 if a Class Z

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. 
 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 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 
  

 3 








 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 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 unless a registration statement under the Act with respect to the Common Stock is effective. 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 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 Brenner, 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 Brenner with respect to such solicitation, if requested by Brenner, and (ii) provide Brenner, and direct the Company’s transfer agent and the Warrant Agent to deliver
to Brenner, 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 Brenner in every respect in connection with Brenner’s solicitation
activities, including, but not limited to, providing to Brenner, at the Company’s cost, a list of record and beneficial holders of the Warrants and circulating a prospectus or offering circular 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), Brenner shall accept payment of the warrant solicitation fee provided in
Section 3.3.5(b) only if it has provided bona fide services to the Company in connection with the exercise of the Warrants and only to the extent that an investor who exercises his Warrants 
  

 4 








 specifically designates, in writing, that Brenner solicited his 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. 
 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 Brenner (“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 between the Company and Brenner 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 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
Brenner, (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 5% of the Warrant Price to Brenner, provided that Brenner delivers to the Warrant Agent within ten
(10) business days from the date on which Brenner 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 Brenner with respect to the exercise by the Underwriters or their affiliates or the Company’s officers or directors of Warrants purchased by it or them upon exercise of the Representative’s Warrants and
still held by any of the Underwriters or them for its or their own account. Brenner 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 Brenner. 
 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

  

 5 








 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. 
 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 the 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 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 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 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. 
  

 7 








 6. Redemption. 
 6.1. Redemption. Subject to Section 6.4 hereof, not less than all of the outstanding Class W Warrants and/or Class Z 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 $.05 per Warrant (“Redemption Price”), provided that the last sales price of the Common Stock
has been at least $7.50 per share in the case of the Class W Warrants and $8.75 per share in the case of the Class Z Warrants, as applicable, 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. The provisions of this Section 6.1 may not be modified, amended or deleted without the prior written consent of Brenner. 
 6.2. Date Fixed for, and Notice of, Redemption. In the event the Company shall elect to redeem all of the Class W and/or Class Z Warrants, as
applicable, 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
Class W or Class Z Warrants, as applicable, 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 Class W or Class Z Warrants, as
applicable, may be exercised in accordance with Section 3 of this 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 record holders of such Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price. 
 6.4 Exclusion of Certain Warrants. 
 (a) 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. The provisions of this Section 6.4(a) may not be modified, amended or deleted without the prior written consent of Brenner. 
 (b) The Insider Warrants may not be redeemed by the Company so long as such Insider Warrants are held by the Insiders. However, once an Insider transfers
his Insider Warrants, such Insider Warrants shall then be redeemable by the Company pursuant to Section 6 hereof. 
  

 8 








 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 Agreement. 
 7.4. Registration of Common Stock. The Company agrees that prior to the commencement of the Exercise Period, it shall 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 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 and to maintain the effectiveness of such
registration statement until the expiration of the Warrants in accordance with the provisions of this Agreement. The provisions of this Section 7.4 may not be modified, amended or deleted without the prior written consent of Brenner.

 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 
  

 9 








 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 which the Warrant Agent shall be a party shall be the successor Warrant Agent under this 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 Agreement. 
  

 10 








 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 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 in good
faith by it pursuant to the provisions of this 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 save 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 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 to the validity of this 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 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 authorization or
reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock will when issued be valid and fully paid and nonassessable. 
 8.5. Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this 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 the Company’s Common Stock through the exercise of Warrants.
