In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

2.2. Effect of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this Warrant Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

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. [Reserved]

2.5. Private Warrants. The Private Warrants will be issued substantially in the form of Exhibit A hereto and be subject to the terms hereof, except that (i) they will be exercisable on a cashless basis at the holder’s option pursuant to Section 3.3 hereof at any time and (ii) they will not be redeemable at any time

3. Terms and Exercise of Warrants.

3.1. Warrant Price. Each Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Warrant Agreement, to purchase from the Company one half (1/2) of an Ordinary Share at $11.50 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 whole share at which Ordinary Shares may be purchased at the time such Warrant is exercised. The Public Warrants may only be exercised for a whole number of Ordinary Shares by a Registered Holder. No fractional shares will be issued.

3.2. Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the later to occur of (i) the Effective Time and (ii) twelve (12) months following the closing of the Public Offering, and terminating at 5:00 p.m., New York City time, on the earlier to occur of (i) five (5) years following the Effective Time and (ii) the date fixed for redemption of the Warrants as provided in Section 6 of this Warrant Agreement (“Expiration Date”). Except with respect to the right to receive the Redemption Price (as set forth in Section 6 hereunder), each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Warrant Agreement shall cease at the close of business on the Expiration Date. The Company may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide written notice of not less than twenty (20) days to Registered Holders of such extension and that such extension shall be identical in duration among all of the then outstanding Warrants.

3.3. Exercise of Warrants.

3.3.1. Cash Exercise. Subject to the provisions of the Warrant and this Warrant Agreement, a Warrant, when countersigned by the Company, may be exercised by the Registered Holder thereof by surrendering it at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, currently being:

Continental Stock Transfer & Trust Company

1 State Street, 30th Floor

New York, New York 10004

with the subscription form, as set forth in the Warrant, duly executed, and by paying in full, in lawful money of the United States, by certified or bank cashier’s check payable to the order of the Warrant Agent or by wire transfer to the Warrant Agent’s JPMorgan bank account, the Warrant Price for each whole Ordinary Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the

4

exchange of the Warrant for the Ordinary Shares, and the issuance of the Ordinary Shares (such exercise, a “Cash Exercise”). A Cash Exercise in accordance with this Section 3.3.1 is available to the Registered Holder only during such times that there is an effective registration statement registering the Ordinary Shares, with the prospectus contained therein being available for the resale of the Ordinary Shares.

3.3.2. Cashless Exercise. Notwithstanding anything contained herein to the contrary, if there is no effective registration statement registering the Ordinary Shares on any day the Registered Holder desires to exercise the Warrants and more than 90 days have passed since the Effective Date, the Registered Holder may exercise the Warrants in whole or in part in lieu of making a cash payment for whole numbers Ordinary Shares, by providing notice to the Chief Financial Officer of the Company in a subscription form of its election to utilize cashless exercise, in which event the Company shall issue to the Holder the number of Ordinary Shares determined as follows:

X = Y [(A-B)/A]

where:

X = the number of Ordinary Shares to be issued to the Holder.

Y = the number of Ordinary Shares with respect to which this Warrant is being exercised.

A = the fair market value of one share of Ordinary Shares.

B = the Warrant Price.

The Registered Holder may not exercise any Warrants in the absence of a registration statement except pursuant to this Section 3.3.2. For purposes of this Section 3.3.2 and Section 4.1, the fair market value of one Ordinary Share is defined as follows (“Fair Market Value”):

(i) if the Ordinary Shares is listed and traded on the New York Stock Exchange, the NYSE America, the NASDAQ Global Select Market, the NASDAQ Global Market or the NASDAQ Capital Market (each, a “Trading Market”), the fair market value shall be deemed the average of the closing price on such Trading Market for the 10 consecutive trading days ending on the third (3rd) trading day immediately prior to the date the subscription form is submitted to the Company in connection with the exercise of the Warrant; or

(ii) if the Company’s Ordinary Shares is not listed on a Trading Market, but is traded in the over-the-counter market, the fair market value shall be deemed to be the average of the bid price on such Trading Market for the 10 consecutive trading days ending on the third (3rd) trading day immediately prior to the date the subscription form is submitted in connection with the exercise of the Warrant; or

5

(iii) if there is no active public market for the Company’s Ordinary Shares, the fair market value of the Ordinary Shares shall be determined in good faith by the Board.

3.3.3. Fractional Shares. Notwithstanding any provision to the contrary contained in this Warrant Agreement, the Company shall not be required to issue any fraction of an Ordinary Share in connection with the exercise of Warrants, and in any case where the Registered Holder would be entitled under the terms of the Warrants to receive a fraction of a share of Ordinary Shares upon the exercise of such Registered Holder’s Warrants, issue or cause to be issued only the largest whole number of Ordinary Shares issuable on such exercise (and such fraction of an Ordinary Shares will be disregarded); provided, that if more than one Warrant certificate is presented for exercise at the same time by the same Registered Holder, the number of whole shares of Ordinary Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Ordinary Shares issuable on exercise of all such Warrants.

3.3.4. Issuance of Certificates. No later than three (3) business days following the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price pursuant to Section 3.3.1 or cashless exercise pursuant to Section 3.3.2, the Company shall issue, or cause to be issued, to the Registered Holder of such Warrant a certificate or certificates representing (or at the option of the Registered Holder, deliver electronically through the facilities of the Depository Trust Corporation) the number of full Ordinary Shares to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and, if such Warrant shall not have been exercised or surrendered in full, a new countersigned Warrant for the number of Ordinary Shares as to which such Warrant shall not have been exercised or surrendered. Notwithstanding the foregoing, the Company shall not deliver, or cause to be delivered, any securities without applicable restrictive legend pursuant to the exercise of a Warrant unless (a) a registration statement under the Securities Act of 1933, as amended (the “Act”) with respect to the Ordinary Shares issuable upon exercise of such Warrants is effective and a current prospectus relating to the shares of Ordinary Shares issuable upon exercise of the Warrants is available for delivery to the Registered Holder of the Warrant or (b) in the opinion of counsel to the Company, the exercise of the Warrants is exempt from the registration requirements of the Act and such securities are qualified for sale or exempt from qualification under applicable securities laws of the states or other jurisdictions in which the Registered Holder resides. Warrants may not be exercised by, or securities issued to, any Registered Holder in any state in which such exercise or issuance would be unlawful. In addition, in no event will the Company be obligated to pay such Registered Holder any cash consideration upon exercise or otherwise “net cash settle” the Warrant.

6

3.3.5. Valid Issuance. All Ordinary Shares issued upon the proper exercise or surrender of a Warrant in conformity with this Warrant Agreement shall be validly issued, fully paid and non-assessable.

3.3.6. Date of Issuance. Each person or entity in whose name any such certificate for Ordinary Shares 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 share 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 share transfer books are open.

4. Adjustments.

4.1. Share Dividends, Splits. If, after the date hereof, and subject to the provisions of Section 4.5 below, the number of outstanding Ordinary Shares is increased by a share dividend payable in Ordinary Shares, or by a forward or reverse split of Ordinary Shares, or other similar event, then, on the effective date of such share dividend, split or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be increased or decreased in proportion to such increase or decrease in outstanding Ordinary Shares. A rights offering to all holders of the Ordinary Shares entitling holders to purchase Ordinary Shares at a price less than the Fair Market Value shall be deemed a share dividend of a number of shares of Ordinary Shares equal to the product of (i) the number of shares of Ordinary Shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for the shares of Ordinary Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per share of Ordinary Shares paid in such rights offering divided by (y) the Fair Market Value. For purposes of this subsection 4.1, if the rights offering is for securities convertible into or exercisable for Ordinary Shares, in determining the price payable for the Ordinary Shares, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion.

4.2. Aggregation of Shares. If, after the date hereof, and subject to the provisions of Section 4.6, the number of outstanding Ordinary Shares is decreased by a consolidation, combination or reclassification of Ordinary Shares or other similar event, then, on the effective date of such consolidation, combination, reclassification or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding Ordinary Shares.

7

4.3. Extraordinary Dividends. If the Company, at any time while the Warrants (or rights to purchase the Warrants) are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to the holders of the Ordinary Shares on account of such Ordinary Shares (or other shares of the Company’s share capital into which the Warrants are convertible), other than (a) as described in subsection 4.1 above or (b) Ordinary Cash Dividends (as defined below) (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and the fair market value (as determined by the Board in good faith) of any securities or other assets paid on each Ordinary Share in respect of such Extraordinary Dividend. For purposes of this subsection 4.3, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis with the per share amounts of all other cash dividends and cash distributions paid on the Ordinary Shares during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Ordinary Shares issuable on exercise of each Warrant) does not exceed $0.50.

4.4. Adjustments in Exercise Price.

4.4.1. Whenever the number of Ordinary Shares purchasable upon the exercise of the Warrants is adjusted, as provided in Sections 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, (a) the numerator of which shall be the number of Ordinary Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (b) the denominator of which shall be the number of Ordinary Shares so purchasable immediately thereafter.

4.5. Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Ordinary Shares (other than a change covered by Sections 4.1 and 4.2 hereof or one that solely affects the par value of such shares of Ordinary Shares), 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 company and that does not result in any reclassification or reorganization of the outstanding Ordinary Shares), or, in the case of any sale or conveyance to another company or entity of the assets or other property of the Company as an entirety or substantially as an entirety, in connection with which the Company is dissolved, the Registered Holders shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the Ordinary Shares of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation,

8

or upon a dissolution following any such sale or transfer, that the Registered Holder would have received if such Registered Holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any reclassification also results in a change in Ordinary Shares covered by Sections 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.

4.6. Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1 – 4.5 the Company shall give written notice to each Registered Holder, at the last address set forth for such Registered Holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.7. Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Warrant Agreement. However, the Company may, at any time, in its sole discretion, make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

4.8. Notice of Certain Transactions. In the event that the Company shall (a) offer to holders of all its Ordinary Shares rights to subscribe for or to purchase any securities convertible into Ordinary Shares or shares of any class or any other securities, rights or options, (b) issue any rights, options or warrants entitling all the holders of Ordinary Shares to subscribe for Ordinary Shares, or (c) make a tender offer, redemption offer or exchange offer with respect to the Ordinary Shares, the Company shall send to the Registered Holders a notice of such action or offer. Such notice shall be mailed to the Registered Holders at their addresses as they appear in the Warrant Register, which shall specify the record date for the purposes of such dividend, distribution or rights, or the date such issuance or event is to take place and the date of participation therein by the holders of Ordinary Shares, if any such date is to be fixed, and shall briefly indicate the effect of such action on the Ordinary Shares and on the number and kind of any other shares and on other property, if any, and the number of Ordinary Shares and other property, if any, issuable upon exercise of each Warrant and the Warrant Price after giving effect to any adjustment pursuant to this Section 4 which would be required as a result of such action. Such notice shall be given as promptly as practicable after the Company has taken any such action.

9

5. Transfer and Exchange of Warrants.

5.1. [Reserved]

5.2. Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant into the Warrant Register, upon surrender of such Warrant for transfer properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon the Company’s request.

5.3. Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that, in the event a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and shall issue new Warrants in exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.

5.4. Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant.

5.5. Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

5.6. Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Warrant Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

6. Redemption.

6.1. Redemption. Subject to the second sentence of this Section 6.1, all (and not less than all) of the outstanding Public Warrants may be redeemed, in whole and not in part, at the option of the Company, at any time from and after the Warrants 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 $0.01 per Warrant

10

(“Redemption Price”); provided that the last sales price of the Ordinary Shares has been equal to or greater than $18.00 per share (subject to adjustment for splits, dividends, recapitalizations and other similar events), for any twenty (20) trading days within a thirty (30) trading day period ending on the third (3rd) business day prior to the date on which notice of redemption is given and provided further that there is a current registration statement in effect with respect to the Ordinary Shares underlying the Warrants for each day in the aforementioned 30-day trading period and continuing each day thereafter until the Redemption Date (defined below). For avoidance of doubt, if and when the Warrants become redeemable by the Company under this Section, the Company may exercise its redemption right, even if it is unable to register or qualify the Ordinary Shares for sale under all applicable state securities laws.

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 (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the date fixed for redemption to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the Warrant Register. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Registered Holder received such notice.

6.3. Exercise After Notice of Redemption. The Warrants may be exercised in accordance with Section 3 of this Warrant Agreement at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption Date; provided that the Company may require the Registered Holder who desires to exercise the Warrant to elect cashless exercise as set forth under Section 3.3.2, and such Registered Holder must exercise the Warrants on a cashless basis if the Company so requires. On and after the Redemption Date, the Registered Holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

6.4. No Other Rights to Cash Payment. Except for a redemption in accordance with this Section 6, no Registered Holder of any Warrant shall be entitled to any cash payment whatsoever from the Company in connection with the ownership, exercise or surrender of any Warrant under this Warrant Agreement.

7. Other Provisions Relating to Rights of Registered Holders of Warrants.

7.1. No Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder 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 shareholders in respect of the meetings of shareholders or the election of directors of the Company or any other matter.

11

7.2. Lost, Stolen Mutilated or Destroyed Warrants. If any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor and date as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

7.3. Reservation of Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary Shares that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement.

7.4. Registration of Ordinary Shares. The Company agrees that as soon as practicable, but in no event later than thirty (30) business days after the Effective Date, it shall use its best efforts to file with the U.S. Securities and Exchange Commission a registration statement for the registration under the Act of the Ordinary Shares issuable upon exercise of the Warrants, and to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of this Agreement. In addition, the Company agrees to use its best efforts to register the Ordinary Shares issuable upon exercise of the Warrants under state blue sky laws, to the extent an exemption is not available.

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 Ordinary Shares 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 thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the Registered Holder of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the Registered Holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by

12

such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and be authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authorities. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but, if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and, upon request of any successor Warrant Agent, the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties and obligations.

8.2.2. Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the transfer agent for the Ordinary Shares not later than the effective date of any such appointment.

8.2.3. Merger or Consolidation of Warrant Agent. Any company or other entity into which the Warrant Agent may be merged or with which it may be consolidated or any company or other entity resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Warrant Agreement without any further act on the part of the Company or the Warrant Agent.

8.3. Fees and Expenses of Warrant Agent.

8.3.1. Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as Warrant Agent hereunder 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.

13

8.4. Liability of Warrant Agent.
