 2.3.2 Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent

 2.5 Public Warrants and Representative’s
Warrants. The Representative’s Warrants shall have the same terms and be in the same form as the Public Warrants except with respect to the Warrant Price as set forth below in Section 3.1. 
  
 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 Public Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price
of $6.00 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

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; provided that any such reduction shall be identical in percentage terms among all of the Warrants, except that any amendment to the terms of the Representative’s Warrants shall be subject to any limitations and conditions
that may be imposed by NASD Corporate Financing Rule 2710. 
  
 3.2 Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the later of the consummation by the Company of a merger, capital stock exchange, asset
acquisition, stock purchase or other similar business combination as described more fully in the Company’s Registration Statement (“Business Combination”) or
                    , 2007 and terminating at 5:00 p.m., New York City time on the earlier to occur of
(i)                     , 2010 or (ii) the date fixed for redemption of the Warrants as provided in Section 6 of this Agreement

any such extension shall be identical in duration among all of the Warrants, except that any amendment to the terms of the Representative’s Warrants shall be subject to any limitations and conditions that may be imposed by NASD Corporate
Financing Rule 2710. 
  

 2 








 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 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 (i) 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 Public Warrant or a Representative’s Warrant and shall have no obligation to settle the Warrant exercise unless a registration statement under the Act with respect to the Common Stock is
effective, subject to the Company’s satisfying its obligations under Section 7.4 to use its best efforts. In the event that a registration statement with respect to the Common Stock underlying a Public Warrant or a Representative’s
Warrant is not effective under the Act, the holder of such Public Warrant or Representative’s Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless. In no event will the Company be
required to net cash settle the warrant exercise. Public Warrants and Representative’s Warrants may not be exercised by, or securities issued to, any registered holder in any state in which such exercise would be unlawful. In the event that a
registration statement is not effective for the exercised Public Warrants and Representative’s Warrants, the purchaser of a unit containing such Warrant, will have paid the full purchase price for the unit solely for the shares included in such
unit. 
  
 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. 
  
 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. 
  

 3 








 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. 
  
 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. 
  

 4 








 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. 
  
 6. Redemption. 
  
 6.1 Redemption. Subject to Section 6.4 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of
the Company, at any time after they become exercisable and prior to their expiration, at the office of the Warrant Agent, upon the notice referred to in Section 6.2., at the price of $.01 per Warrant (“Redemption Price”), provided
that the last sales price of the Common Stock has been equal to or greater than $11.50 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. The provisions of this Section 6.1 may not be modified, amended or deleted without the prior written consent of JMP Securities. 
  
 6.2 Date Fixed for, and Notice of, Redemption. In the event the Company shall elect to redeem all of
the Warrants, the Company shall fix a date for the redemption. Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than 30 days prior to the date fixed for redemption to the registered holders of the
Warrants to be redeemed at their last addresses as they shall appear on the Warrant Register. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the registered holder received such
notice. 
  
 6.3 Exercise After Notice of
Redemption. The Warrants may be exercised in accordance with Section 3 of this Warrant Agreement at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2. hereof and prior to the time and date
fixed for redemption. On and after the redemption date, the 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. The provisions of this Section 6.4 may not be modified, amended or deleted without the prior written
consent of JMP Securities. 
  
 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. 
  

 5 








 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. 
  
 7.4 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 Warrant Agreement. The provisions of this Section 7.4 may not be modified, amended or deleted without the prior written consent of JMP Securities. 
  
 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. 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 Warrant Agreement without any further act.

 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

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 Warrant Agreement. 
  
 8.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own negligence, willful misconduct or bad faith. The
Company agrees to indemnify the Warrant Agent and 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 Warrant Agreement
except as a result of the Warrant Agent’s negligence, willful misconduct, or bad faith. 
  
 8.4.3 Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Warrant Agreement or with
respect to the validity or execution of any Warrant (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Warrant Agreement or in any Warrant; nor shall it be
responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment;
nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Warrant Agreement or any Warrant or as to whether any shares of
Common Stock will when issued be valid and fully paid and nonassessable. 
  
 8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Warrant Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things,
shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all moneys received by the Warrant Agent for the purchase of shares of the Company’s Common Stock through the
