      THE
      PURCHASE OF

    


    490,800
      UNITS

    


    OF

    


    STACCATO
      ACQUISITION CORP.

     

    1.  Purchase
      Option.
      

     

    THIS
      CERTIFIES THAT, in consideration of $100.00 duly paid by or on behalf of
      EarlyBirdCapital, Inc. (“Holder”),
      as
      registered owner of this Purchase Option, to Staccato Acquisition Corp.
      (“Company”),
      Holder is entitled, at any time or from time to time upon the later of the
      consummation of a Business Combination and ___________, 2008 (“Commencement
      Date”),
      and
      at or before 5:00 p.m., New York City local time, _________, 2013 (“Expiration
      Date”),
      but
      not thereafter, to subscribe for, purchase and receive, in whole or in part,
      up
      to four hundred ninety thousand eight hundred (490,800) units (“Units”)
      of the
      Company, each Unit consisting of one share of the Company’s common stock, par
      value $0.0001 per share (“Common
      Stock”),
      and
      one warrant (“Warrant(s)”) expiring
      four years from the date hereof (“Effective
      Date”).
      Each
      Warrant is the same as the warrants included in the Units being registered
      for
      sale to the public by way of the Registration Statement (“Public
      Warrants”).
      If
      the Expiration Date is a day on which banking institutions are authorized by
      law
      to close, then this Purchase Option may be exercised on the next succeeding
      day
      which is not such a day in accordance with the terms herein. During the period
      ending on the Expiration Date, the Company agrees not to take any action that
      would terminate this Purchase Option. This Purchase Option is initially
      exercisable at $10.00 per Unit so purchased; provided,
      however,
      that
      upon the occurrence of any of the events specified in Section 6 hereof, the
      rights granted by this Purchase Option, including the exercise price per Unit
      and the number of Units (and Common Stock and Warrants) to be received upon
      such
      exercise, shall be adjusted as therein specified. The term “Exercise Price”
shall mean the initial exercise price or the adjusted exercise price, depending
      on the context. 

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    2.  Exercise.
      

     

    2.1  Exercise
      Form.
      In
      order to exercise this Purchase Option, the exercise form attached hereto must
      be duly executed and completed and delivered to the Company, together with
      this
      Purchase Option and payment of the Exercise Price for the Units being purchased
      payable in cash or by certified check or official bank check. If the
      subscription rights represented hereby shall not be exercised at or before
      5:00
      p.m., New York City local time, on the Expiration Date this Purchase Option
      shall become and be void without further force or effect, and all rights
      represented hereby shall cease and expire. 

     

    2.2  Legend.
      Each
      certificate for the securities purchased under this Purchase Option shall bear
      a
      legend as follows unless such securities have been registered under the
      Securities Act of 1933, as amended (“Act”):
      

     

    “The
      securities represented by this certificate have not been registered under the
      Securities Act of 1933, as amended (“Act”) or applicable state law. The
      securities may not be offered for sale, sold or otherwise transferred except
      pursuant to an effective registration statement under the Act, or pursuant
      to an
      exemption from registration under the Act and applicable state law.”


     

    2.3  Cashless
      Exercise.
      

     

    2.3.1  Determination
      of Amount.
      In lieu
      of the payment of the Exercise Price multiplied by the number of Units for
      which
      this Purchase Option is exercisable (and in lieu of being entitled to receive
      Common Stock and Warrants) in the manner required by Section 2.1, the Holder
      shall have the right (but not the obligation) to convert any exercisable but
      unexercised portion of this Purchase Option into Units (“Cashless
      Exercise Right”)
      as
      follows: upon exercise of the Cashless Exercise Right, the Company shall deliver
      to the Holder (without payment by the Holder of any of the Exercise Price in
      cash) that number of Units (or that number of shares of Common Stock and
      Warrants comprising that number of Units) equal to the quotient obtained by
      dividing (x) the “Value” (as defined below) of the portion of the Purchase
      Option being converted by (y) the Current Market Value (as defined below).
      The
“Value” of the portion of the Purchase Option being converted shall equal the
      remainder derived from subtracting (a) (i) the Exercise Price multiplied by
      (ii)
      the number of Units underlying the portion of this Purchase Option being
      converted from (b) the Current Market Value of a Unit multiplied by the number
      of Units underlying the portion of the Purchase Option being converted. As
      used
      herein, the term “Current Market Value” per Unit at any date means: (A) in the
      event that neither the Units nor Public Warrants are still trading, the
      remainder derived from subtracting (x) the exercise price of the Warrants
      multiplied by the number of shares of Common Stock issuable upon exercise of
      the
      Warrants underlying one Unit from (y) (i) the Current Market Price of the Common
      Stock multiplied by (ii) the number of shares of Common Stock underlying one
      Unit, which shall include the shares of Common Stock underlying the Warrants
      included in such Unit; (B) in the event that the Units, Common Stock and Public
      Warrants are still trading, (i) if the Units are listed on a national securities
      exchange or quoted on the OTC Bulletin Board (or successor exchange), the last
      sale price of the Units in the principal trading market for the Units as
      reported by the exchange, Nasdaq or the Financial Industry Regulatory Authority
      (“FINRA”),
      as
      the case may be, on the last trading day preceding the date in question; or
      (ii)
      if the Units are not listed on a national securities exchange or quoted on
      the
      OTC Bulletin Board (or successor exchange), but is traded in the residual
      over-the-counter market, the closing bid price for Units on the last trading
      day
      preceding the date in question for which such quotations are reported by the
      Pink Sheets, LLC or similar publisher of such quotations; and (C) in the event
      that the Units are not still trading but the Common Stock and Public Warrants
      underlying the Units are still trading, the Current Market Price of the Common
      Stock plus the product of (x) the Current Market Price of the Public Warrants
      and (y) the number of Shares underlying the Warrants included in one Unit.
      The
“Current Market Price” shall mean (i) if the Common Stock (or Public Warrants,
      as the case may be) is listed on a national securities exchange or quoted on
      the
      OTC Bulletin Board (or successor exchange), the last sale price of the Common
      Stock (or Public Warrants) in the principal trading market for the Common Stock
      as reported by the exchange, Nasdaq or FINRA, as the case may be, on the last
      trading day preceding the date in question; (ii) if the Common Stock (or Public
      Warrants, as the case may be) is not listed on a national securities exchange
      or
      quoted on the OTC Bulletin Board (or successor exchange), but is traded in
      the
      residual over-the-counter market, the closing bid price for the Common Stock
      (or
      Public Warrants) on the last trading day preceding the date in question for
      which such quotations are reported by the Pink Sheets, LLC or similar publisher
      of such quotations; and (iii) if the fair market value of the Common Stock
      cannot be determined pursuant to clause (i) or (ii) above, such price as the
      Board of Directors of the Company shall determine, in good faith. In the event
      the Public Warrants have expired and are no longer exercisable, no “Value” shall
      be attributed to the Warrants underlying this Purchase Option. Additionally,
      in
      the event that this Purchase Option is exercised pursuant to this Section 2.3
      and the Public Warrants are still trading, the “Value” shall be reduced by the
      difference between the Warrant Exercise Price and the exercise price of the
      Public Warrants multiplied by the number of Warrants underlying the Units
      included in the portion of this Purchase Option being converted.

    2.3.2  Mechanics
      of Cashless Exercise.
      The
      Cashless Exercise Right may be exercised by the Holder on any business day
      on or
      after the Commencement Date and not later than the Expiration Date by delivering
      the Purchase Option with the duly executed exercise form attached hereto with
      the cashless exercise section completed to the Company, exercising the Cashless
      Exercise Right and specifying the total number of Units the Holder will purchase
      pursuant to such Cashless Exercise Right. 

     

    2.4  No
      Obligation to Net Cash Settle.
      Notwithstanding anything to the contrary contained in this Purchase Option,
      in
      no event will the Company be required to net cash settle the exercise of the
      Purchase Option or the Warrants underlying the Purchase Option. The holder
      of
      the Purchase Option and the Warrants underlying the Purchase Option will not
      be
      entitled to exercise the Purchase Option or the Warrants underlying such
      Purchase Option unless a registration statement is effective, or an exemption
      from the registration requirements is available at such time and, if the holder
      is not able to exercise the Purchase Option or underlying Warrants, the Purchase
      Option and/or the underlying Warrants, as applicable, will expire worthless.
      

     

    3.  Transfer.
      

     

    3.1  General
      Restrictions.
      The
      registered Holder of this Purchase Option, by its acceptance hereof, agrees
      that
      it will not sell, transfer, assign, pledge or hypothecate this Purchase Option
      for a period of one hundred eighty (180) days following the Effective Date
      to
      anyone other than (i) EBC or an underwriter or selected dealer in connection
      with the public offering (“Offering”),
      or
      (ii) a bona fide officer or partner of EBC or of any such underwriter or
      selected dealer. On and after the first anniversary of the Effective Date,
      transfers to others may be made subject to compliance with or exemptions from
      applicable securities laws. In order to make any permitted assignment, the
      Holder must deliver to the Company the assignment form attached hereto duly
      executed and completed, together with the Purchase Option and payment of all
      transfer taxes, if any, payable in connection therewith. The Company shall
      within five business days transfer this Purchase Option on the books of the
      Company and shall execute and deliver a new Purchase Option or Purchase Options
      of like tenor to the appropriate assignee(s) expressly evidencing the right
      to
      purchase the aggregate number of Units purchasable hereunder or such portion
      of
      such number as shall be contemplated by any such assignment.

    3.2  Restrictions
      Imposed by the Act.
      The
      securities evidenced by this Purchase Option shall not be transferred unless
      and
      until (i) the Company has received the opinion of counsel for the Holder that
      the securities may be transferred pursuant to an exemption from registration
      under the Act and applicable state securities laws, the availability of which
      is
      established to the reasonable satisfaction of the Company (the Company hereby
      agreeing that the opinion of Greenberg Traurig, LLP shall be deemed satisfactory
      evidence of the availability of an exemption), or (ii) a registration statement
      or a post-effective amendment to the Registration Statement relating to such
      securities has been filed by the Company and declared effective by the
      Securities and Exchange Commission (the “Commission”)
      and
      compliance with applicable state securities law has been established.


     

    4.  New
      Purchase Options to be Issued.
      

     

    4.1  Partial
      Exercise or Transfer.
      Subject
      to the restrictions in Section 3 hereof, this Purchase Option may be exercised
      or assigned in whole or in part. In the event of the exercise or assignment
      hereof in part only, upon surrender of this Purchase Option for cancellation,
      together with the duly executed exercise or assignment form and funds sufficient
      to pay any Exercise Price and/or transfer tax, the Company shall cause to be
      delivered to the Holder without charge a new Purchase Option of like tenor
      to
      this Purchase Option in the name of the Holder evidencing the right of the
      Holder to purchase the number of Units purchasable hereunder as to which this
      Purchase Option has not been exercised or assigned. 

     

    4.2  Lost
      Certificate.
      Upon
      receipt by the Company of evidence satisfactory to it of the loss, theft,
      destruction or mutilation of this Purchase Option and of reasonably satisfactory
      indemnification or the posting of a bond, the Company shall execute and deliver
      a new Purchase Option of like tenor and date. Any such new Purchase Option
      executed and delivered as a result of such loss, theft, mutilation or
      destruction shall constitute a substitute contractual obligation on the part
      of
      the Company. 

     

    5.  Registration
      Rights.
      

     

    5.1  Demand
      Registration.
      

     

    5.1.1  Grant
      of Right.
      The
      Company, upon written demand (“Initial
      Demand Notice”)
      of the
      Holder(s) of at least 51% of the Purchase Option and/or the underlying Units
      and/or the underlying securities (“Majority
      Holders”),
      agrees to use its best efforts to register (the “Demand
      Registration”)
      under
      the Act on one occasion, all or any portion of the Purchase Option requested
      by
      the Majority Holders in the Initial Demand Notice and all of the securities
      underlying such Purchase Option, including the Units, the Common Stock, the
      Warrants and the Common Stock underlying the Warrants (collectively, the
“Registrable
      Securities”).
      On
      such occasion, the Company will use its best efforts to file a registration
      statement or a post-effective amendment to the Registration Statement covering
      the Registrable Securities within sixty (60) days after receipt of the Initial
      Demand Notice and use its best efforts to have such registration statement
      or
      post-effective amendment declared effective as soon as possible thereafter.
      The
      demand for registration may be made at any time during a period of five years
      beginning on the Effective Date. The Initial Demand Notice shall specify the
      number of shares of Registrable Securities proposed to be sold and the intended
      method(s) of distribution thereof. The Company will notify all holders of the
      Purchase Option and/or Registrable Securities of the demand within ten (10)
      days
      from the date of the receipt of any such Initial Demand Notice. Each holder
      of
      Registrable Securities who wishes to include all or a portion of such holder’s
      Registrable Securities in the Demand Registration (each such holder including
      shares of Registrable Securities in such registration, a “Demanding
      Holder”)
      shall
      so notify the Company within fifteen (15) days after the receipt by the holder
      of the notice from the Company. Upon any such request, the Demanding Holders
      shall be entitled to have their Registrable Securities included in the Demand
      Registration, subject to Section 5.1.4.

    5.1.2  Effective
      Registration.
      A
      registration will not count as a Demand Registration until the registration
      statement filed with the Commission with respect to such Demand Registration
      has
      been declared effective and the Company has complied with all of its obligations
      under this Agreement with respect thereto; provided,
      however,
      that
      if, after such registration statement has been declared effective, the offering
      of Registrable Securities pursuant to a Demand Registration is interfered with
      by any stop order or injunction of the Commission or any other governmental
      agency or court, the registration statement with respect to such Demand
      Registration will be deemed not to have been declared effective, unless and
      until, (i) such stop order or injunction is removed, rescinded or otherwise
      terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter
      elect to continue the offering. 

     

    5.1.3  Underwritten
      Offering.
      If the
      Majority Holders so elect and such holders so advise the Company as part of
      the
      Initial Demand Notice, the offering of such Registrable Securities pursuant
      to
      such Demand Registration shall be in the form of an underwritten offering.
      In
      such event, the right of any holder to include its Registrable Securities in
      such registration shall be conditioned upon such holder’s participation in such
      underwriting and the inclusion of such holder’s Registrable Securities in the
      underwriting to the extent provided herein. All Demanding Holders proposing
      to
      distribute their securities through such underwriting shall enter into an
      underwriting agreement in customary form with the underwriter or underwriters
      selected for such underwriting by the Majority Holders. 

     

    5.1.4  Reduction
      of Offering.
      If the
      managing underwriter or underwriters for a Demand Registration that is to be
      an
      underwritten offering advises the Company and the Demanding Holders in writing
      that the dollar amount or number of shares of Registrable Securities which
      the
      Demanding Holders desire to sell, taken together with all other shares of Common
      Stock or other securities which the Company desires to sell and the shares
      of
      Common Stock, if any, as to which registration has been requested pursuant
      to
      written contractual piggy-back registration rights held by other stockholders
      of
      the Company who desire to sell, exceeds the maximum dollar amount or maximum
      number of shares that can be sold in such offering without adversely affecting
      the proposed offering price, the timing, the distribution method, or the
      probability of success of such offering (such maximum dollar amount or maximum
      number of shares, as applicable, the “Maximum
      Number of Shares”),
      then
      the Company shall include in such registration: (i) first, the Registrable
      Securities as to which Demand Registration has been requested by the Demanding
      Holders (pro rata in accordance with the number of shares that each such Person
      has requested be included in such registration, regardless of the number of
      shares held by each such Person (such proportion is referred to herein as
“Pro
      Rata”))
      that
      can be sold without exceeding the Maximum Number of Shares; (ii) second, to
      the
      extent that the Maximum Number of Shares has not been reached under the
      foregoing clause (i), the shares of Common Stock or other securities that the
      Company desires to sell that can be sold without exceeding the Maximum Number
      of
      Shares; (iii) third, to the extent that the Maximum Number of Shares has not
      been reached under the foregoing clauses (i) and (ii), the shares of Common
      Stock or other securities registrable pursuant to the terms of the Registration
      Rights Agreement between the Company and the initial investors in the Company,
      dated as of _________, 2008 (the “Registration
      Rights Agreement”
and
      such registrable securities, the “Investor
      Securities”)
      as to
      which “piggy-back” registration has been requested by the holders thereof, Pro
      Rata, that can be sold without exceeding the Maximum Number of Shares; and
      (iv)
      fourth, to the extent that the Maximum Number of Shares have not been reached
      under the foregoing clauses (i), (ii), and (iii), the shares of Common Stock
      or
      other securities for the account of other persons that the Company is obligated
      to register pursuant to written contractual arrangements with such persons
      and
      that can be sold without exceeding the Maximum Number of Shares.

    5.1.5  Withdrawal.
      If a
      majority-in-interest of the Demanding Holders disapprove of the terms of any
      underwriting or are not entitled to include all of their Registrable Securities
      in any offering, such majority-in-interest of the Demanding Holders may elect
      to
      withdraw from such offering by giving written notice to the Company and the
      underwriter or underwriters of their request to withdraw prior to the
      effectiveness of the registration statement filed with the Commission with
      respect to such Demand Registration. If the majority-in-interest of the
      Demanding Holders withdraws from a proposed offering relating to a Demand
      Registration, then the Company does not have to continue its obligations under
      Section 5.1 with respect to such proposed offering. 

     

    5.1.6  Terms.
      The
      Company shall bear all fees and expenses attendant to registering the
      Registrable Securities, including the expenses of any legal counsel selected
      by
      the Holders to represent them in connection with the sale of the Registrable
      Securities, but the Holders shall pay any and all underwriting commissions.
      The
      Company agrees to use its reasonable best efforts to qualify or register the
      Registrable Securities in such states as are reasonably requested by the
      Majority Holder(s); provided,
      however,
      that in
      no event shall the Company be required to register the Registrable Securities
      in
      a state in which such registration would cause (i) the Company to be obligated
      to qualify to do business in such state, or would subject the Company to
      taxation as a foreign corporation doing business in such jurisdiction or (ii)
      the principal stockholders of the Company to be obligated to escrow their shares
      of capital stock of the Company. The Company shall use its best efforts to
      cause
      any registration statement or post-effective amendment filed pursuant to the
      demand rights granted under Section 5.1.1 to remain effective for a period
      of
      nine consecutive months from the effective date of such registration statement
      or post-effective amendment. 

     

    5.2  Piggy-Back
      Registration.
      

     

    5.2.1  Piggy-Back
      Rights.
      If at
      any time during the seven year period commencing on the Effective Date the
      Company proposes to file a registration statement under the Act with respect
      to
      an offering of equity securities, or securities or other obligations exercisable
      or exchangeable for, or convertible into, equity securities, by the Company
      for
      its own account or for stockholders of the Company for their account (or by
      the
      Company and by stockholders of the Company including, without limitation,
      pursuant to Section 5.1), other than a registration statement (i) filed in
      connection with any employee stock option or other benefit plan, (ii) for an
      exchange offer or offering of securities solely to the Company’s existing
      stockholders, (iii) for an offering of debt that is convertible into equity
      securities of the Company or (iv) for a dividend reinvestment plan, then the
      Company shall (x) give written notice of such proposed filing to the holders
      of
      Registrable Securities as soon as practicable but in no event less than ten
      (10)
      days before the anticipated filing date, which notice shall describe the amount
      and type of securities to be included in such offering, the intended method(s)
      of distribution, and the name of the proposed managing underwriter or
      underwriters, if any, of the offering, and (y) offer to the holders of
      Registrable Securities in such notice the opportunity to register the sale
      of
      such number of shares of Registrable Securities as such holders may request
      in
      writing within five (5) days following receipt of such notice (a “Piggy-Back
      Registration”).
      The
      Company shall cause such Registrable Securities to be included in such
      registration and shall use its best efforts to cause the managing underwriter
      or
      underwriters of a proposed underwritten offering to permit the Registrable
      Securities requested to be included in a Piggy-Back Registration on the same
      terms and conditions as any similar securities of the Company and to permit
      the
      sale or other disposition of such Registrable Securities in accordance with
      the
      intended method(s) of distribution thereof. All holders of Registrable
      Securities proposing to distribute their securities through a Piggy-Back
      Registration that involves an underwriter or underwriters shall enter into
      an
      underwriting agreement in customary form with the underwriter or underwriters
      selected for such Piggy-Back Registration.

    5.2.2  Reduction
      of Offering.
      If the
      managing underwriter or underwriters for a Piggy-Back Registration that is
      to be
      an underwritten offering advises the Company and the holders of Registrable
      Securities in writing that the dollar amount or number of shares of Common
      Stock
      which the Company desires to sell, taken together with shares of Common Stock,
      if any, as to which registration has been demanded pursuant to written
      contractual arrangements with persons other than the holders of Registrable
      Securities hereunder, the Registrable Securities as to which registration has
      been requested under this Section 5.2, and the shares of Common Stock, if any,
      as to which registration has been requested pursuant to the written contractual
      piggy-back registration rights of other stockholders of the Company, exceeds
      the
      Maximum Number of Shares, then the Company shall include in any such
      registration:

      that the Maximum Number of Shares has not been reached under the foregoing
      clause (A), the shares of Common Stock or other securities, if any, comprised

      registration rights of such security holders, Pro Rata, that can be sold without
      exceeding the Maximum Number of Shares; and (C) third, to the extent that the
      Maximum Number of shares has not been reached under the foregoing clauses (A)

    (b)  If
      the
      registration is a “demand” registration undertaken at the demand of holders of
      Investor Securities, (A) first, the shares of Common Stock or other securities
      for the account of the demanding persons, Pro Rata, that can be sold without

      register pursuant to written contractual arrangements with such persons, that

    (c)  If

      other than either the holders of Registrable Securities or of Investor
      Securities, (A) first, the shares of Common Stock or other securities for the
      account of the demanding persons that can be sold without exceeding the Maximum
      Number of Shares; (B) second, to the extent that the Maximum Number of Shares

      and (B), collectively the shares of Common Stock or other securities comprised
      of Registrable Securities and Investor Securities, Pro Rata, as to which
      registration has been requested pursuant to the terms hereof and of the

      the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum
      Number of Shares has not been reached under the foregoing clauses (A), (B)
      and
      (C), the shares of Common Stock or other securities for the account of other
      persons that the Company is obligated to register pursuant to written
      contractual arrangements with such persons, that can be sold without exceeding
      the Maximum Number of Shares.

    5.2.3  Withdrawal.
      Any
      holder of Registrable Securities may elect to withdraw such holder’s request for
      inclusion of Registrable Securities in any Piggy-Back Registration by giving
      written notice to the Company of such request to withdraw prior to the
      effectiveness of the registration statement. The Company (whether on its own
      determination or as the result of a withdrawal by persons making a demand
      pursuant to written contractual obligations) may withdraw a registration
      statement at any time prior to the effectiveness of the registration statement.
      Notwithstanding any such withdrawal, the Company shall pay all expenses incurred
      by the holders of Registrable Securities in connection with such Piggy-Back
      Registration as provided in Section 5.2.4. 

     

    5.2.4  Terms.
      The
      Company shall bear all fees and expenses attendant to registering the
      Registrable Securities, including the expenses of any legal counsel selected
      by
      the Holders to represent them in connection with the sale of the Registrable
      Securities but the Holders shall pay any and all underwriting commissions
      related to the Registrable Securities. In the event of such a proposed
      registration, the Company shall furnish the then Holders of outstanding
      Registrable Securities with not less than fifteen days written notice prior
      to
      the proposed date of filing of such registration statement. Such notice to
      the
      Holders shall continue to be given for each applicable registration statement
      filed (during the period in which the Purchase Option is exercisable) by the
      Company until such time as all of the Registrable Securities have been
      registered and sold. The Holders of the Registrable Securities shall exercise
      the “piggy-back” rights provided for herein by giving written notice, within ten
      days of the receipt of the Company’s notice of its intention to file a
      registration statement. The Company shall use its best efforts to cause any
      registration statement filed pursuant to the above “piggyback” rights to remain
      effective for at least nine months from the date that the Holders of the
      Registrable Securities are first given the opportunity to sell all of such
      securities. 

     

    5.3  General
      Terms.
      

     

    5.3.1  Indemnification.
      The
      Company shall indemnify the Holder(s) of the Registrable Securities to be sold
      pursuant to any registration statement hereunder and each person, if any, who
      controls such Holders within the meaning of Section 15 of the Act or Section
      20(a) of the Securities Exchange Act of 1934, as amended (“Exchange
      Act”),
      against all loss, claim, damage, expense or liability (including all reasonable
      attorneys’ fees and other expenses reasonably incurred in investigating,
      preparing or defending against litigation, commenced or threatened, or any
      claim
      whatsoever whether arising out of any action between the underwriter and the
      Company or between the underwriter and any third party or otherwise) to which
      any of them may become subject under the Act, the Exchange Act or otherwise,
      arising from such registration statement but only to the same extent and with
      the same effect as the provisions pursuant to which the Company has agreed
      to
      indemnify the underwriters contained in Section 5 of the Underwriting Agreement
      between the Company, EBC and the other underwriters named therein dated the
      Effective Date. The Holder(s) of the Registrable Securities to be sold pursuant
      to such registration statement, and their successors and assigns, shall
      severally, and not jointly, indemnify the Company, its officers and directors
      and each person, if any, who controls the Company within the meaning of Section
      15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim,
      damage, expense or liability (including all reasonable attorneys’ fees and other
      expenses reasonably incurred in investigating, preparing or defending against
      any claim whatsoever) to which they may become subject under the Act, the
      Exchange Act or otherwise, arising from information furnished by or on behalf
      of
      such Holders, or their successors or assigns, in writing, for specific inclusion
      in such registration statement to the same extent and with the same effect
      as
      the provisions contained in Section 5 of the Underwriting Agreement pursuant
      to
      which the underwriters have agreed to indemnify the Company.

    5.3.2  Exercise
      of Purchase Options.
      Nothing
      contained in this Purchase Option shall be construed as requiring the Holder(s)
      to exercise their Purchase Options or Warrants underlying such Purchase Options
      prior to or after the initial filing of any registration statement or the
      effectiveness thereof. 

     

    5.3.3  Documents
      Delivered to Holders.
      The
      Company shall furnish EBC, as representative of the Holders participating in
      any
      of the foregoing offerings, a signed counterpart, addressed to the participating
      Holders, of (i) an opinion of counsel to the Company, dated the effective date
      of such registration statement (and, if such registration includes an
      underwritten public offering, an opinion dated the date of the closing under
      any
      underwriting agreement related thereto), and (ii) a “cold comfort” letter dated
      the effective date of such registration statement (and, if such registration
      includes an underwritten public offering, a letter dated the date of the closing
      under the underwriting agreement) signed by the independent public accountants
      who have issued a report on the Company’s financial statements included in such
      registration statement, in each case covering substantially the same matters
      with respect to such registration statement (and the prospectus included
      therein) and, in the case of such accountants’ letter, with respect to events
      subsequent to the date of such financial statements, as are customarily covered
      in opinions of issuer’s counsel and in accountants’ letters delivered to
      underwriters in underwritten public offerings of securities. The Company shall
      also deliver promptly to EBC, as representative of the Holders participating
      in
      the offering, the correspondence and memoranda described below and copies of
      all
      correspondence between the Commission and the Company, its counsel or auditors
      and all memoranda relating to discussions with the Commission or its staff
      with
      respect to the registration statement and permit EBC, as representative of
      the
      Holders, to do such investigation, upon reasonable advance notice, with respect
      to information contained in or omitted from the registration statement as it
      deems reasonably necessary to comply with applicable securities laws or rules
      of
FINRA.
      Such
      investigation shall include access to books, records and properties and
      opportunities to discuss the business of the Company with its officers and
      independent auditors, all to such reasonable extent and at such reasonable
      times
      and as often as EBC, as representative of the Holders, shall reasonably request.
      The Company shall not be required to disclose any confidential information
      or
      other records to EBC, as representative of the Holders, or to any other person,
      until and unless such persons shall have entered into reasonable confidentiality
      agreements (in form and substance reasonably satisfactory to the Company),
      with
      the Company with respect thereto. 

     

    5.3.4  Underwriting
      Agreement.
      The
      Company shall enter into an underwriting agreement with the managing
      underwriter(s), if any, selected by any Holders whose Registrable Securities
      are
      being registered pursuant to this Section 5, which managing underwriter shall
      be
      reasonably acceptable to the Company. Such agreement shall be reasonably
      satisfactory in form and substance to the Company, each Holder and such managing
      underwriters, and shall contain such representations, warranties and covenants
      by the Company and such other terms as are customarily contained in agreements
      of that type used by the managing underwriter. The Holders shall be parties
      to
      any underwriting agreement relating to an underwritten sale of their Registrable
      Securities and may, at their option, require that any or all the
      representations, warranties and covenants of the Company to or for the benefit
      of such underwriters shall also be made to and for the benefit of such Holders.
      Such Holders shall not be required to make any representations or warranties
      to
      or agreements with the Company or the underwriters except as they may relate
      to
      such Holders and their intended methods of distribution. Such Holders, however,
      shall agree to such covenants and indemnification and contribution obligations
      for selling stockholders as are customarily contained in agreements of that
      type
      used by the managing underwriter. Further, such Holders shall execute
      appropriate custody agreements and otherwise cooperate fully in the preparation
      of the registration statement and other documents relating to any offering
      in
      which they include securities pursuant to this Section 5. Each Holder shall
      also
      furnish to the Company such information regarding itself, the Registrable
      Securities held by it, and the intended method of disposition of such securities
      as shall be reasonably required to effect the registration of the Registrable
      Securities.

    5.3.5  Rule
      144 Sale.
      Notwithstanding anything contained in this Section 5 to the contrary, the
      Company shall have no obligation pursuant to Sections 5.1 or 5.2 to use its
      best
      efforts to obtain the registration of Registrable Securities held by any Holder
      (i) where such Holder would then be entitled to sell under Rule 144 within
      any
      three-month period (or such other period prescribed under Rule 144 as may be
      provided by amendment thereof) all of the Registrable Securities then held
      by
      such Holder, and (ii) where the number of Registrable Securities held by such
      Holder is within the volume limitations under paragraph (e) of Rule 144
      (calculated as if such Holder were an affiliate within the meaning of Rule
      144).


     

    5.3.6  Supplemental
      Prospectus.
      Each
      Holder agrees, that upon receipt of any notice from the Company of the happening
      of any event as a result of which the prospectus included in the registration
      statement, as then in effect, includes an untrue statement of a material fact
      or
      omits to state a material fact required to be stated therein or necessary to
      make the statements therein not misleading in light of the circumstances then
      existing, such Holder will immediately discontinue disposition of Registrable
      Securities pursuant to the registration statement covering such Registrable
      Securities until such Holder’s receipt of the copies of a supplemental or
      amended prospectus, and, if so desired by the Company, such Holder shall deliver
      to the Company (at the expense of the Company) or destroy (and deliver to the
      Company a certificate of such destruction) all copies, other than permanent
      file
      copies then in such Holder’s possession, of the prospectus covering such
      Registrable Securities current at the time of receipt of such notice.


     

    5.3.7  Rule
      144.
      The
      Company covenants that it shall file any reports required to be filed by it
      under the Act and the Exchange Act and shall take such further action as the
      holders of Registrable Securities may reasonably request, all to the extent
      required from time to time to enable such holders to sell Registrable Securities
      without registration under the Act within the limitations of the exemptions
      provided by Rule 144, as such rule may be amended from time to time, or any
      similar rule or regulation hereafter adopted by the Securities and Exchange
      Commission. 

     

    6.  Adjustments.
      

     

    6.1  Adjustments
      to Exercise Price and Number of Securities.
      The
      Exercise Price and the number of Units underlying the Purchase Option shall
      be
      subject to adjustment from time to time as hereinafter set forth: 

     

    6.1.1  Stock
      Dividends - Split-Ups.
      If
      after the date hereof, and subject to the provisions of Section 6.2 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 thereof, the number of shares
      of Common Stock underlying each of the Units purchasable hereunder shall be
      increased in proportion to such increase in outstanding shares. In such case,
      the number of shares of Common Stock, and the exercise price applicable thereto,
      underlying the Warrants underlying each of the Units purchasable hereunder
      shall
      be adjusted in accordance with the terms of the Warrants. For example, if the
      Company declares a two-for-one stock dividend and at the time of such dividend
      this Purchase Option is for the purchase of one Unit at $10.00 per whole Unit
      (each Warrant underlying the Units is exercisable for $6.00 per share), upon
      effectiveness of the dividend, this Purchase Option will be adjusted to allow
      for the purchase of one Unit at $10.00 per Unit, each Unit entitling the holder
      to receive two shares of Common Stock and two Warrants (each Warrant exercisable
      for $3.00 per share). 

     

    6.1.2  Aggregation
      of Shares.
      If
      after the date hereof, and subject to the provisions of Section 6.2, the number
      of outstanding shares of Common Stock is decreased by a consolidation,
      combination or reclassification of shares of Common Stock or other similar
      event, then, on the effective date thereof, the number of shares of Common
      Stock
      underlying each of the Units purchasable hereunder shall be decreased in
      proportion to such decrease in outstanding shares. In such case, the number
      of
      shares of Common Stock, and the exercise price applicable thereto, underlying
      the Warrants underlying each of the Units purchasable hereunder shall be
      adjusted in accordance with the terms of the Warrants.

    6.1.3  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 6.1.1 or 6.1.2 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 property of the Company
      as an
      entirety or substantially as an entirety in connection with which the Company
      is
      dissolved, the Holder of this Purchase Option shall have the right thereafter
      (until the expiration of the right of exercise of this Purchase Option) to
      receive upon the exercise hereof, for the same aggregate Exercise Price payable
      hereunder immediately prior to such event, 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, by a Holder of the number of shares of
      Common Stock of the Company obtainable upon exercise of this Purchase Option
      and
      the underlying Warrants immediately prior to such event; and if any
      reclassification also results in a change in shares of Common Stock covered
      by
      Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections
      6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall
      similarly apply to successive reclassifications, reorganizations, mergers or
      consolidations, sales or other transfers. 

     

    6.1.4  Changes
      in Form of Purchase Option.
      This
      form of Purchase Option need not be changed because of any change pursuant
      to
      this Section, and Purchase Options issued after such change may state the same
      Exercise Price and the same number of Units as are stated in the Purchase
      Options initially issued pursuant to this Agreement. The acceptance by any
      Holder of the issuance of new Purchase Options reflecting a required or
      permissive change shall not be deemed to waive any rights to an adjustment
      occurring after the Commencement Date or the computation thereof. 

     

    6.2  Substitute
      Purchase Option.
      In case
      of any consolidation of the Company with, or merger of the Company with, or
      merger of the Company into, another corporation (other than a consolidation
      or
      merger which does not result in any reclassification or change of the
      outstanding shares of Common Stock), the corporation formed by such
      consolidation or merger shall execute and deliver to the Holder a supplemental
      Purchase Option providing that the holder of each Purchase Option then
      outstanding or to be outstanding shall have the right thereafter (until the
      stated expiration of such Purchase Option) to receive, upon exercise of such
      Purchase Option, the kind and amount of shares of stock and other securities
      and
      property receivable upon such consolidation or merger, by a holder of the number
      of shares of Common Stock of the Company for which such Purchase Option might
      have been exercised immediately prior to such consolidation, merger, sale or
      transfer. Such supplemental Purchase Option shall provide for adjustments which
      shall be identical to the adjustments provided in Section 6. The above provision
      of this Section shall similarly apply to successive consolidations or mergers.
      

     

    6.3  Elimination
      of Fractional Interests.
      The
      Company shall not be required to issue certificates representing fractions
      of
      shares of Common Stock or Warrants upon the exercise of the Purchase Option,
      nor
      shall it be required to issue scrip or pay cash in lieu of any fractional
      interests, it being the intent of the parties that all fractional interests
      shall be eliminated by rounding any fraction up to the nearest whole number
      of
      Warrants, shares of Common Stock or other securities, properties or rights.

    7.  Reservation
      and Listing.
      The
      Company shall at all times reserve and keep available out of its authorized
      shares of Common Stock, solely for the purpose of issuance upon exercise of
      this
      Purchase Option or the Warrants underlying this Purchase Option, such number
      of
      shares of Common Stock or other securities, properties or rights as shall be
      issuable upon the exercise thereof. The Company covenants and agrees that,
      upon
      exercise of this Purchase Options and payment of the Exercise Price therefor,
      all shares of Common Stock and other securities issuable upon such exercise
      shall be duly and validly issued, fully paid and non-assessable and not subject
      to preemptive rights of any stockholder. The Company further covenants and
      agrees that upon exercise of the Warrants underlying this Purchase Option and
      payment of the respective Warrant exercise price therefor, all shares of Common
      Stock and other securities issuable upon such exercise shall be duly and validly
      issued, fully paid and non-assessable and not subject to preemptive rights
      of
      any stockholder. As long as this Purchase Option shall be outstanding, the
      Company shall use its best efforts to cause all (i) Units issuable upon exercise
      of this Purchase Option, (ii) shares of Common Stock included in the Units
      issuable upon exercise of this Purchase Option, (iii) Warrants included in
      the
      Units issuable upon exercise of this Purchase Option and (iv) shares of Common
      Stock issuable upon exercise of the Warrants included in the Units issuable
      upon
      exercise of this Purchase Option to be listed (subject to official notice of
      issuance) on all securities exchanges (or, if applicable on the OTC Bulletin
      Board or any successor trading market) on which the Units, the Common Stock
      or
      the Public Warrants issued to the public in connection herewith may then be
      listed and/or quoted. 

     

    8.  Certain
      Notice Requirements.
      

     

    8.1  Holder’s
      Right to Receive Notice.
      Nothing
      herein shall be construed as conferring upon the Holders the right to vote
      or
      consent as a stockholder for the election of directors or any other matter,
      or
      as having any rights whatsoever as a stockholder of the Company. If, however,
      at
      any time prior to the expiration of this Purchase Option and its exercise,
      any
      of the events described in Section 8.2 shall occur, then, in one or more of
      said
      events, the Company shall give written notice of such event at least fifteen
      (15) days prior to the date fixed as a record date or the date of closing the
      transfer books for the determination of the stockholders entitled to such
      dividend, distribution, conversion or exchange of securities or subscription
      rights, or entitled to vote on such proposed dissolution, liquidation, winding
      up or sale. Such notice shall specify such record date or the date of the
      closing of the transfer books, as the case may be. Notwithstanding the
      foregoing, the Company shall deliver to each Holder a copy of each notice given
      to the other stockholders of the Company at the same time and in the same manner
      that such notice is given to the stockholders. 

     

    8.2  Events
      Requiring Notice.
      The
      Company shall be required to give the notice described in this Section 8 upon
      one or more of the following events: (i) if the Company shall take a record
      of
      the holders of its shares of Common Stock for the purpose of entitling them
      to
      receive a dividend or distribution payable otherwise than in cash, or a cash
      dividend or distribution payable otherwise than out of retained earnings, as
      indicated by the accounting treatment of such dividend or distribution on the
      books of the Company, or (ii) the Company shall offer to all the holders of
      its
      Common Stock any additional shares of capital stock of the Company or securities
      convertible into or exchangeable for shares of capital stock of the Company,
      or
      any option, right or warrant to subscribe therefor, (iii) a dissolution,
      liquidation or winding up of the Company (other than in connection with a
      consolidation or merger) or a sale of all or substantially all of its property,
      assets and business shall be proposed, (iv) if the Company shall delivery a
      notice to holders of the warrants of a redemption pursuant to Section 6.2 of
      the
      Warrant Agreement or (v) if the Company shall deliver a notice to the Holder
      pursuant to Section 5 of this Purchase Option.

    8.3  Notice
      of Change in Exercise Price.
      The
      Company shall, promptly after an event requiring a change in the Exercise Price
      pursuant to Section 6 hereof, send notice to the Holders of such event and
      change (“Price
      Notice”).
      The
      Price Notice shall describe the event causing the change and the method of
      calculating same and shall be certified as being true and accurate by the
      Company’s President and Chief Financial Officer. 

     

    8.4  Transmittal
      of Notices.
      All
      notices, requests, consents and other communications under this Purchase Option

    9.  Miscellaneous.
      

     

    9.1  Amendments.
      The
      Company and EBC may from time to time supplement or amend this Purchase Option
      without the approval of any of the Holders in order to cure any ambiguity,
      to
      correct or supplement any provision contained herein that may be defective
      or
      inconsistent with any other provisions herein, or to make any other provisions
      in regard to matters or questions arising hereunder that the Company and EBC
      may
      deem necessary or desirable and that the Company and EBC deem shall not
      adversely affect the interest of the Holders. All other modifications or
      amendments shall require the written consent of and be signed by the party
      against whom enforcement of the modification or amendment is sought.


     

    9.2  Headings.
      The
      headings contained herein are for the sole purpose of convenience of reference,
      and shall not in any way limit or affect the meaning or interpretation of any
      of
      the terms or provisions of this Purchase Option.

    9.3  Entire
      Agreement.
      This
      Purchase Option (together with the other agreements and documents being
      delivered pursuant to or in connection with this Purchase Option) constitutes
      the entire agreement of the parties hereto with respect to the subject matter
      hereof, and supersedes all prior agreements and understandings of the parties,
      oral and written, with respect to the subject matter hereof. 

     

    9.4  Binding
      Effect.
      This
      Purchase Option shall inure solely to the benefit of and shall be binding upon,
      the Holder and the Company and their permitted assignees, respective successors,
      legal representative and assigns, and no other person shall have or be construed
      to have any legal or equitable right, remedy or claim under or in respect of
      or
      by virtue of this Purchase Option or any provisions herein contained.


     

    9.5  Governing
      Law; Submission to Jurisdiction.
      This
      Purchase Option shall be governed by and construed and enforced in accordance
      with the laws of the State of New York, without giving effect to conflict of
      laws. The Company hereby agrees that any action, proceeding or claim against
      it
      arising out of, or relating in any way to this Purchase Option shall be brought
      and enforced in the courts of the State of New York or of the United States
      of
      America for the Southern District of New York, and irrevocably submits to such
      jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives
      any objection to such exclusive jurisdiction and that such courts represent
      an
      inconvenient forum. Any process or summons to be served upon the Company may
      be
      served by transmitting a copy thereof by registered or certified mail, return
      receipt requested, postage prepaid, addressed to it at the address set forth
      in
      Section 8 hereof. Such mailing shall be deemed personal service and shall be
      legal and binding upon the Company in any action, proceeding or claim. The
      Company and the Holder agree that the prevailing party(ies) in any such action
      shall be entitled to recover from the other party(ies) all of its reasonable
      attorneys’ fees and expenses relating to such action or proceeding and/or
      incurred in connection with the preparation therefor. 

     

    9.6  Waiver,
      Etc.
      The
      failure of the Company or the Holder to at any time enforce any of the
      provisions of this Purchase Option shall not be deemed or construed to be a
      waiver of any such provision, nor to in any way affect the validity of this
      Purchase Option or any provision hereof or the right of the Company or any
      Holder to thereafter enforce each and every provision of this Purchase Option.
      No waiver of any breach, non-compliance or non-fulfillment of any of the
      provisions of this Purchase Option shall be effective unless set forth in a
      written instrument executed by the party or parties against whom or which
      enforcement of such waiver is sought; and no waiver of any such breach,
      non-compliance or non- fulfillment shall be construed or deemed to be a waiver
      of any other or subsequent breach or non-compliance. 

     

    9.7  Execution
      in Counterparts.
      This
      Purchase Option may be executed in one or more counterparts, and by the
      different parties hereto in separate counterparts, each of which shall be deemed
      to be an original, but all of which taken together shall constitute one and
      the
      same agreement, and shall become effective when one or more counterparts has
      been signed by each of the parties hereto and delivered to each of the other
      parties hereto. 

     

    9.8  Exchange
      Agreement.
      As a
      condition of the Holder’s receipt and acceptance of this Purchase Option, Holder
      agrees that, at any time prior to the complete exercise of this Purchase Option
      by Holder, if the Company and EBC enter into an agreement (“Exchange
      Agreement”)
      pursuant to which they agree that all outstanding Purchase Options will be
      exchanged for securities or cash or a combination of both, then Holder shall
      agree to such exchange and become a party to the Exchange Agreement.
